General Description of the Trust and its Funds

The Trust currently consists of more than 330 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the SEC under the 1940 Act. The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates to the following Funds:

•

iShares ESG Aware Aggressive Allocation ETF

•

iShares ESG Aware Conservative Allocation ETF

•

iShares ESG Aware Growth Allocation ETF

•

iShares ESG Aware Moderate Allocation ETF

Each Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (each, an “Underlying Index” and collectively, the Underlying Indexes). Each Fund is managed by BFA, an indirect wholly-owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the respective Underlying Index identified in the applicable Prospectus for that Fund.

Each Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a designated portfolio of securities, assets or other positions (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities” or “Creation Basket”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Funds are listed for trading on Cboe BZX Exchange, Inc. (the “Listing Exchange” or “Cboe BZX”), a national securities exchange. Shares of each Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units by Authorized Participants (as defined in the Creation and Redemption of Creation Units-Role of the Authorized Participant section of this SAI) and, generally, in exchange for portfolio securities and a Cash Amount (as defined in the Redemption of Creation Units section of this SAI). Creation Units typically are a specified number of shares, generally 25,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash and reserves the right to permit or require the substitution of Deposit Securities in lieu of cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement that the Authorized Participant (as defined in the Portfolio Holding Information section of this SAI) maintain with the Trust collateral as set forth in the handbook for Authorized Participants. The Trust may use such collateral at any time to purchase Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees and other costs associated with creations or redemptions that include a cash portion may be higher than the transaction fees and other costs associated with in-kind creations or redemptions. In all cases, conditions with respect to creations and redemptions of shares and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in each Fund is contained in the Shareholder Information section of each Fund's Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the applicable Prospectus.

Shares of each Fund are listed for trading, and trade throughout the day, on the Listing Exchange and in other secondary markets. Shares of the Funds may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if, among other things: (i) a Fund is no longer eligible to operate in reliance on Rule 6c-11 under the Investment Company Act; (ii) any of the other listing requirements are not continuously maintained; or (iii) any event shall occur or condition shall exist that, in the opinion of the

Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares of a Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

The Trust reserves the right to adjust the share price of the Funds in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Funds or an investor's equity interest in the Funds.

Investment Strategies and Risks of the Funds

Each Fund seeks to achieve its investment objective by investing a substantial portion of its assets in the Underlying Funds, which are iShares ESG Aware MSCI USA ETF, iShares ESG Aware MSCI USA Small-Cap ETF, iShares ESG Aware MSCI EAFE ETF, iShares ESG Aware MSCI EM ETF and iShares ESG Aware U.S. Aggregate Bond ETF. Each Fund’s assets are allocated among the Underlying Funds in accordance with the Fund’s investment objective and policies, and the remaining assets are generally allocated to money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”). Each Fund operates as an index fund and is not actively managed. Adverse performance of a security in a Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Fund’s Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Funds do not seek leveraged returns, certain instruments used by the Funds may have a leveraging effect as described below.

Each Fund will invest at least 80% of its assets, exclusive of collateral held from securities lending, in the component securities of its Underlying Index and may invest up to 20% of its assets in certain index futures, options, options on index futures, swap contracts or other derivatives, as related to its Underlying Index and its component securities, cash and cash equivalents, other investment companies, as well as in securities and other instruments not included in the Underlying Index, but which BFA believes will help each Fund track its Underlying Index. Each Fund seeks to track the investment results of its Underlying Index before fees and expenses of the Fund.

Set forth below is more detailed information regarding types of instruments in which the Underlying Funds, and in some cases, the Funds, may invest, strategies BFA may employ in pursuit of a Fund's or an Underlying Fund's investment objective, and related risks.

Asset-Backed and Commercial Mortgage-Backed Securities. Certain of the Underlying Funds may invest in asset-backed securities (“ABS”) and commercial mortgage-backed securities (“CMBS”). ABS are securities backed by installment contracts, credit-card receivables or other assets. CMBS are securities backed by commercial real estate properties. Both ABS and CMBS represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of ABS and CMBS varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, the stated maturity of an ABS or CMBS may be shortened, and the security’s total return may be difficult to predict precisely. Also see Mortgage Pass-Through Securities and Mortgage Securities below.

Beginning in the second half of 2007 through 2009, the market for ABS and mortgage-backed securities (“MBS”) experienced substantially, often dramatically, lower valuations and reduced liquidity. These instruments continue to be subject to liquidity constraints, price volatility, credit downgrades and increases in default rates and, therefore, may be more difficult to value and more difficult to dispose of than previously.

Bonds. Certain of the Underlying Funds may invest in bonds. A bond is an interest-bearing security issued by a U.S. or non-U.S. company or governmental unit. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. Bonds generally are used by issuers to borrow money from investors.

An issuer may have the right to redeem or “call” a bond before maturity, in which case a fund may have to reinvest the proceeds at lower market rates. Similarly, a fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed-rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. When an investor purchases a fixed-rate bond at a price that is greater than its face value, the investor is purchasing the bond at a premium. Conversely, when an investor purchases a fixed-rate bond at a price that is less than its face value, the investor is purchasing the bond at a discount. Fixed-rate bonds that are purchased at a discount pay less current income than securities with comparable yields that are purchased at face value, with the result that prices for such fixed-rate securities can be more volatile than prices for such securities that are purchased at face value. Other types of bonds bear interest at an interest rate that is adjusted periodically. Interest rates on “floating rate” or “variable rate” bonds may be higher or lower than current market rates for fixed-rate bonds of comparable quality with similar final maturities. Because of their adjustable interest rates, the value of “floating rate” or “variable rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed-rate bonds, but their value may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. An Underlying Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on an issuer’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (backed by specified collateral).

Borrowing. Each Fund may borrow for temporary or emergency purposes, including to meet payments due from redemptions or to facilitate the settlement of securities or other transactions.

The purchase of securities while borrowings are outstanding may have the effect of leveraging a Fund. The incurrence of leverage increases a Fund’s exposure to risk, and borrowed funds are subject to interest costs that will reduce net income. Purchasing securities while borrowings are outstanding creates special risks, such as the potential for greater volatility in the NAV of Fund shares and in the yield on a Fund’s portfolio. In addition, the interest expenses from borrowings may exceed the income generated by a Fund’s portfolio and, therefore, the amount available (if any) for distribution to shareholders as dividends may be reduced. BFA may determine to maintain outstanding borrowings if it expects that the benefits to a Fund’s shareholders will outweigh the current reduced return.

Certain types of borrowings by a Fund must be made from a bank or may result in a Fund being subject to covenants in credit agreements relating to asset coverage, portfolio composition requirements and other matters. It is not anticipated that observance of such covenants would impede BFA’s management of a Fund’s portfolio in accordance with a Fund’s investment objectives and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require a Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Corporate Bonds. Certain of the Underlying Funds may invest in investment grade and/or high yield corporate bonds. The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in the market rate of interest, the credit rating of the issuer, the issuer’s performance and perceptions of the issuer in the marketplace. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Currency Transactions. A currency forward contract is an over-the-counter (“OTC”) obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days greater than two days from the date on which the contract is agreed upon by the parties, at a price set at the time of the contract. A non-deliverable currency forward is an OTC currency forward settled in a specified currency, on a specified date, based on the difference between the agreed-upon exchange rate and the market exchange rate. A currency futures contract is a contract that trades on an organized futures

exchange involving an obligation to deliver or acquire a specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. The Underlying Funds that may engage in currency transactions do not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Underlying Funds' assets that are denominated in a non-U.S. currency. A Fund may enter into non-U.S. currency forward and non-U.S. currency futures transactions to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected may be highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of an Underlying Fund's return with the performance of its underlying index and may lower the Underlying Fund’s return. Each Underlying Fund could experience losses if the value of its currency forwards, options or futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market or otherwise. In addition, each Underlying Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

Diversification Status. Each Fund is classified as a diversified fund under the 1940 Act. This means that each Fund may not purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and (ii) securities of other investment companies) if, with respect to 75% of its total assets, (a) more than 5% of the Fund’s total assets would be invested in securities of that issuer or (b) the Fund would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, each Fund may invest more than 5% of its assets in one issuer. Under the 1940 Act, each Fund cannot change its classification from diversified to non-diversified without shareholder approval.

Each Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.

Equity Securities. Equity securities generally have greater price volatility than fixed-income securities. The market price of equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally; particular industries, sectors or geographic regions represented in those markets; or individual issuers. The types of developments that may affect an issuer of an equity security include management performance, financial leverage and reduced demand for the issuer's goods or services. Common and preferred stock represent equity or ownership interests in an issuer. Preferred stock, however, pays dividends at a specified rate and has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

Futures, Options on Futures and Securities Options. Futures contracts, options on futures and securities options may be used by a Fund and certain of the Underlying Funds to simulate investment in their respective underlying index, to facilitate trading or to reduce transaction costs. Each Fund or an Underlying Fund may enter into futures contracts and options on futures that are traded on a U.S. or non-U.S. futures exchange. Each Fund or an Underlying Fund will not use futures, options on futures or securities options for speculative purposes. Each Fund and each Underlying Fund intend to use futures and options on futures in accordance with Rule 4.5 of the Commodity Futures Trading Commission (the “CFTC”) promulgated under the Commodity Exchange Act (“CEA”). BFA, with respect to certain Underlying Funds, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that BFA, with respect to such Funds or an Underlying Fund, is not subject to registration or regulation as a commodity pool operator under the CEA. See the Regulation Regarding Derivatives section of this SAI for more information.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. Each Fund or an Underlying Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. Upon entering into a futures contract, a Fund or an Underlying Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is similar to a performance bond or good faith deposit on the contract and is returned to the Fund or an Underlying Fund upon termination of the futures contract if all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” will be made to and from the broker daily as the price of the instrument or index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, each Fund or an Underlying Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s or an Underlying Fund's existing position in the contract. An option on a futures contract, as contrasted with a direct investment in such a contract, gives the purchaser the right, but no obligation, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract.

The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of each Fund or an Underlying Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the “strike price,” less the premium received from writing the put. The Funds or an Underlying Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of their portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Securities options may be used by a Fund to obtain access to securities in its Underlying Index or to dispose of securities in its Underlying Index at favorable prices, to invest cash in a securities index that offers similar exposure to that provided by its Underlying Index or otherwise to achieve the Fund’s objective of tracking its Underlying Index. A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at an exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. Each Fund or an Underlying Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. Each Fund or an Underlying Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Each Fund or an Underlying Fund may purchase or sell securities options on a U.S. or non-U.S. securities exchange or in the OTC market through a transaction with a dealer. Options on a securities index are typically settled on a net basis based on the appreciation or depreciation of the index level over the strike price. Options on single name securities may be cash- or physically-settled, depending upon the market in which they are traded. Options may be structured so as to be exercisable only on certain dates or on a daily basis. Options may also be structured to have conditions to exercise (i.e., “Knock-in Events”) or conditions that trigger termination (i.e., “Knock-out Events”).

Investments in Underlying Funds. Each Underlying Fund is a type of investment company referred to as an exchange-traded fund (“ETF”). Each Underlying Fund is designed to track a particular index and is advised by BFA. Shares of the Underlying Funds are listed for trading on national securities exchanges and trade throughout the day on those exchanges and other secondary markets. There can be no assurance that the requirements of the national securities exchanges necessary to maintain the listing of shares of the Underlying Funds will continue to be met. A national securities exchange may, but is not required to, remove the shares of the Underlying Funds from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of an Underlying Fund, there are fewer than 50 record and/or beneficial holders of the shares for 30 or more consecutive trading days, (ii) the value of an Underlying Fund's underlying index is no longer calculated or available, or (iii) any other event shall occur or condition exist that, in the opinion of the

national securities exchange, makes further dealings on the national securities exchange inadvisable. A national securities exchange will remove the shares of an Underlying Fund from listing and trading upon termination of such Underlying Fund. Shares of each Underlying Fund trade on exchanges at prices at, above or below their most recent NAV. The per share NAV of each Underlying Fund is calculated at the end of each business day and fluctuates with changes in the market value of such Underlying Fund's holdings since the most recent calculation. The trading prices of an Underlying Fund's shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of an Underlying Fund's shares may deviate significantly from NAV during periods of market volatility. Any of these factors may lead to an Underlying Fund's shares trading at a premium or discount to NAV. Exchange prices are not expected to correlate exactly with an Underlying Fund's NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to an Underlying Fund's creations and redemptions or the existence of extreme market volatility may result in trading prices of Underlying Fund shares that differ significantly from NAV. If the Funds purchase shares of the Underlying Funds at a time when the market price of an Underlying Fund's shares are at a premium to the NAV or sells at a time when the market price of an Underlying Fund is at a discount to the NAV, then the Funds may sustain losses.

As in the case of other publicly-traded securities, brokers' commissions on buying or selling shares of the Underlying Funds will be based on negotiated commission rates at customary levels. An investment in an ETF generally presents the same primary risks as an investment in an open-end investment company that is not exchange-traded and that has the same investment objectives, strategies, and policies. However, ETFs are subject to the following risks that do not apply to an open-end investment company that is not exchange-traded: (i) the market price of the ETF's shares may trade at a discount to their net asset value; (ii) an active trading market for an ETF's shares may not develop or be maintained; or (iii) trading of an ETF's shares may be halted if the listing exchange's officials deem such action appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large swings in stock prices) halts stock trading generally.

Lending Portfolio Securities. Each Fund may lend portfolio securities to certain borrowers that BFA determines to be creditworthy, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of a Fund if, as a result, the aggregate value of all securities loans of the particular Fund exceeds one-third of the value of such Fund’s total assets (including the value of the collateral received). A Fund may terminate a loan at any time and obtain the return of the securities loaned. Each Fund receives, by way of substitute payment, the value of any interest or cash or non-cash distributions paid on the loaned securities that it would have otherwise received if the securities were not on loan.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Funds are compensated by any positive difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral received by the Fund for such loans, and uninvested cash, may be reinvested in certain short-term instruments either directly on behalf of each Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk.

Each Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund to act as securities lending agent. To the extent that a Fund engages in securities lending, BlackRock Institutional Trust Company, N.A. (“BTC”) acts as securities lending agent for the Fund, subject to the overall supervision of BFA. BTC administers the lending program in accordance with guidelines approved by the Trust's Board of Trustees (the “Board,” the trustees of which are the “Trustees”). JPMorgan Chase Bank, N.A. (“JPMorgan”) serves as custodian for the Funds in connection with certain securities lending activities.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees a Fund has agreed to pay a borrower), foreign exchange risk (i.e., the risk of a shortfall at default when a cash collateral investment is denominated in a currency other than the currency of the assets being loaned due to movements in foreign exchange rates), and credit, legal, counterparty and market risks (including the risk that market events, including but not limited to corporate actions, could lead the Fund to lend securities that are trading at a premium due to increased demand, or to recall loaned securities or to lend less or not at all, which could lead to reduced securities lending revenue). If a Fund were to lend out securities that are subject to a corporate action and commit to the borrower a particular election as determined by the Funds’ investment adviser, the benefit the Fund would receive in respect of committing to such

election may or may not be less than the benefit the Fund would have received from making a different election in such corporate action. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund’s ability to participate in a corporate action event may be impacted, or the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This latter event could trigger adverse tax consequences for a Fund. A Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments received by a Fund representing dividends paid on securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with a Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income. There could also be changes in the status of issuers under applicable laws and regulations, including tax regulations, that may impact the regulatory or tax treatment of loaned securities and could, for example, result in a delay in the payment of dividend equivalent payments owed to a Fund (as permitted by applicable law).

Regulations adopted by global prudential regulators require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many securities lending agreements, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such agreements, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Fund’s ability to terminate existing securities lending agreements or to realize amounts to be received under such agreements.

Liquidity Risk Management. Rule 22e-4 under the Investment Company Act (the “Liquidity Rule”) requires open-end funds, including ETFs such as the Funds, to establish a liquidity risk management program (the “Liquidity Program”) and enhance disclosures regarding fund liquidity. As required by the Liquidity Rule, the Funds have implemented a Liquidity Program, and the Board, including a majority of the Independent Trustees of the Trust, has appointed BFA as the administrator of the Liquidity Program. Under the Liquidity Program, BFA assesses, manages, and periodically reviews each Fund’s liquidity risk and classifies each investment held by a Fund as a “highly liquid investment,” “moderately liquid investment,” “less liquid investment” or “illiquid investment.” The Liquidity Rule defines “liquidity risk” as the risk that a Fund could not meet requests to redeem shares issued by a Fund without significant dilution of the remaining investors’ interest in a Fund. The liquidity of a Fund's portfolio investments is determined based on relevant market, trading and investment-specific considerations under the Liquidity Program. There are exclusions from certain portions of the liquidity risk management program requirements for “in-kind” ETFs, as defined in the Liquidity Rule. To the extent that an investment is deemed to be an illiquid investment or a less liquid investment, a Fund can expect to be exposed to greater liquidity risk.

Non-Diversification Risk. Certain of the Underlying Funds may be classified as “non-diversified.” This means that the Underlying Funds may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Underlying Funds may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities and Emerging Markets Securities. Certain of the Underlying Funds may invest in the securities of non-U.S. issuers, which involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or potentially confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, potential restrictions of the flow of international capital, generally less liquid and less efficient securities markets, generally greater price volatility, less publicly available information about issuers, higher transaction and custody costs, delays and risks attendant in settlement procedures, difficulties in enforcing contractual obligations, less developed judicial systems to settle disputes, lesser liquidity and significantly smaller market capitalization of most non-U.S. securities markets, substantial government interference with the economy and transaction costs of foreign currency conversions. The Underlying Funds may have difficulty valuing such securities due to these or other considerations. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy with respect to growth of gross domestic product (“GDP”), rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. In addition, changes in foreign exchange rates also will affect the value of securities denominated or quoted in currencies other than the U.S. dollar. Certain

foreign markets have specific geographical risks such as a heightened likelihood of earthquakes, tsunamis, or volcanoes. Certain foreign markets also experience acts of terrorism, territorial disputes or other defense concerns. These situations may have a significant impact on the economies of, and investments in, these geographic areas.

To the extent an Underlying Fund invests in publicly traded common stocks of non-U.S. issuers, certain investments in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “depositary receipts”). Depositary receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. Depositary receipts may not necessarily be denominated in the same currency as their underlying securities. ADRs typically are issued by a U.S. bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental depositary receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities. GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designed for use in European securities markets. GDRs are tradable both in the U.S. and in Europe and are designed for use throughout the world. The Funds or an Underlying Fund may invest in depositary receipts through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute interest holder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities. The issuers of unsponsored depositary receipts are not obligated to disclose material information in the U.S. and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts.

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose each Underlying Fund to additional risks associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and liquidity risk. Unsponsored programs, which are not sanctioned by the issuer of the underlying common stock, generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in sponsored depositary receipts.

Obligations of Foreign Governments, Supranational Entities and Banks. The Funds and certain of the Underlying Funds may invest in U.S. dollar-denominated short-term obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions, agencies or instrumentalities that are determined by BFA to be of comparable quality to the other obligations in which such Underlying Funds may invest. Certain foreign governments, specifically foreign governments in emerging markets, historically have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest, and declared moratoria on the payment of principal and interest on their sovereign debts. Certain of the Underlying Funds may also invest in debt obligations of supranational entities. Supranational entities include international organizations designated or supported by governmental entities to promote economic reconstruction or development and international banking institutions and related government agencies. Examples include the International Bank for Reconstruction and Development (the World Bank), the Asian Development Bank and the InterAmerican Development Bank. The percentage of the Underlying Funds’ assets invested in obligations of foreign governments and supranational entities will vary depending on the relative yields of such securities, the economic and financial markets of the countries in which the investments are made and the interest rate climate of such countries. Certain of the Underlying Funds may invest a portion of their total assets in high-quality, short-term (one year or less) debt obligations of foreign branches of U.S. banks or U.S. branches of foreign banks that are denominated in and pay interest in U.S. dollars.

Emerging Markets. Some non-U.S. markets in which certain of the Underlying Funds invest are considered to be emerging markets. Investment in these emerging markets subjects an Underlying Fund to a greater risk of loss than investments in developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in developed markets.

Ratings. An investment-grade rating generally means the security or issuer is rated investment-grade by one or more of Moody’s, S&P Global Ratings, Fitch, Dominion Bond Rating Service Limited (“Dominion”), or another credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC, or is unrated but considered to be of equivalent quality by BFA. Generally, bonds rated Baa3 or above by Moody’s, BBBL or above by Dominion or BBB- or above by S&P Global Ratings and Fitch are considered “investment-grade” securities, bonds rated Baa are considered medium grade obligations subject to moderate credit risk and may possess certain speculative characteristics, while bonds rated BBB are regarded as having adequate capacity to meet financial commitments.

Subsequent to purchase by the applicable Underlying Fund, a rated security may cease to be rated or its rating may be reduced below an investment-grade rating. Bonds rated below Baa3 by Moody’s or below BBB- by S&P Global Ratings or Fitch are generally considered below investment-grade quality and are obligations of issuers that are generally considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such lower-rated securities are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Please see Appendix B of this SAI for a description of each rating category of Moody's, S&P Global Ratings, Fitch and Dominion and BFA's treatment of investments that are not rated by any of the rating agencies.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”) or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

BFA has claimed an exclusion from the definition of the term “commodity pool operator” under the CEA pursuant to Rule 4.5 under the CEA with respect to each of the Funds. BFA is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA with respect to the Funds.

The iShares ESG Aware Aggressive Allocation ETF, iShares ESG Aware Conservative Allocation ETF, iShares ESG Aware Growth Allocation ETF and iShares ESG Aware Moderate Allocation ETF (the “No-Action Letter Funds”) may also have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (the term “underlying fund” for purposes of the no-action letter referenced below may include, but is not limited to, certain securitized vehicles, mortgage or international real estate investment trusts, business development companies and investment companies that may invest in CFTC Derivatives or in any of the foregoing), and therefore may be viewed by the CFTC as commodity pools. BFA may not have transparency into the holdings of these underlying funds because they are not advised by BFA. To address this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the adviser of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to CFTC Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the adviser of the No-Action Letter Funds, has filed a claim with the CFTC for the Funds to rely on this no-action relief. Accordingly, BFA is not currently subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Funds.

Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverable forwards, are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) in the U.S. and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Swaps, non-deliverable forwards and certain other derivatives traded in the OTC market are subject to variation margin and initial margin requirements. Implementation of the margining and other provisions of the Dodd-Frank Act regarding clearing, mandatory trading, reporting and documentation of swaps and other derivatives have impacted and may continue to impact the costs to a Fund of trading these instruments and, as a result, may affect returns to investors in a Fund.

Rule 18f-4 under the Investment Company Act permits a Fund to enter into Derivatives Transactions (as defined below) and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the Investment Company Act. Section 18 of the Investment Company Act, among other things, prohibits open-end funds, including the Funds, from issuing or selling any “senior security,” other than borrowing from a bank (subject to a requirement to maintain 300% “asset coverage”).

Under Rule 18f-4, “Derivatives Transactions” include the following: (1) any swap, security-based swap (including a contract for differences), futures contract, forward contract, option (excluding purchased options), any combination of the foregoing, or any similar instrument, under which a Fund is or may be required to make any payment or delivery of cash or other assets during the life of the instrument or at maturity or early termination, whether as margin or settlement payment or otherwise; (2) any short sale borrowing; (3) reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, and borrowed bonds), if a Fund elects to treat these transactions as Derivatives Transactions under Rule 18f-4; and (4) when-issued or forward-settling securities (e.g., firm and standby commitments, including to-be-announced (“TBA”) commitments, and dollar rolls) and non-standard settlement cycle securities, unless the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”).

Unless a Fund is relying on the Limited Derivatives User Exception (as defined below), the Fund must comply with Rule 18f-4 with respect to its Derivatives Transactions. Rule 18f-4, among other things, requires a Fund to adopt and implement a comprehensive written derivatives risk management program (“DRMP”) and comply with a relative or absolute limit on Fund leverage risk calculated based on value-at-risk (“VaR”). The DRMP is administered by a “derivatives risk manager,” who is appointed by the Board, including a majority of Independent Directors/Trustees, and periodically reviews the DRMP and reports to the Board.

Rule 18f-4 provides an exception from the DRMP, VaR limit and certain other requirements if a Fund's “derivatives exposure” (as defined in Rule 18f-4) is limited to 10% of its net assets (as calculated in accordance with Rule 18f-4) and the Fund adopts and implements written policies and procedures reasonably designed to manage its derivatives risks (the “Limited Derivatives User Exception”).

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., an Underlying Fund) acquires a security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed-upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by an Underlying Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Underlying Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are determined to (A) have exceptionally strong capacity to meet their financial obligations and (B) are sufficiently liquid such that they can be sold at approximately their carrying value in the ordinary course of business within seven days.

Repurchase agreements pose certain risks for an Underlying Fund that utilizes them. Such risks are not unique to the Underlying Funds, but are inherent in repurchase agreements. The Underlying Funds seek to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with a longer maturity may be subject to greater price fluctuations than higher quality collateral and collateral with a shorter maturity. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, an Underlying Fund would likely retain the status of an unsecured creditor of the counterparty (i.e., the position an Underlying Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, an Underlying Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that each Fund or an Underlying Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund or an Underlying Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if each Fund or an Underlying Fund has an opportunity to earn a rate of interest on the cash derived from

these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and each Fund or an Underlying Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund or an Underlying Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of each Fund or Underlying Fund’s assets. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained through reverse repurchase agreements may be invested in additional securities.

Rule 18f-4 under the Investment Company Act permits each Fund or an Underlying Fund to enter into reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, borrowed bonds) notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that each Fund or an Underlying Fund either (i) complies with the 300% asset coverage ratio with respect to such transactions and any other borrowings in the aggregate, or (ii) treats such transactions as Derivatives Transactions under Rule 18f-4. (See “Regulation Regarding Derivatives” above.)

Securities of Investment Companies. Each Underlying Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law, regulation, exemptive order or SEC staff guidance. Under the 1940 Act, a fund’s investment in investment companies is limited to, subject to certain exceptions, (i) 3% of the total outstanding voting stock of any one investment company, (ii) 5% of the fund’s total assets with respect to any one investment company, and (iii) 10% of the fund’s total assets with respect to investment companies in the aggregate. Other investment companies in which an Underlying Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by an Underlying Fund. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect a fund's pro rata share of the fees and expenses incurred by investing in other investment companies.

An Underlying Fund may purchase ETF shares for the same reason it would purchase (and as an alternative to purchasing) futures contracts – to obtain relatively low-cost exposure to the stock market while maintaining flexibility to meet the liquidity needs of the Underlying Fund. ETF shares enjoy several advantages over futures contracts. Depending on the market, the holding period, and other factors, ETF shares can be less costly than futures contracts. In addition, ETF shares can be purchased for smaller sums and offer exposure to market sectors and styles for which there is no suitable or liquid futures contract. An Underlying Fund may also purchase ETF shares for other purposes, including improving its ability to track its underlying index. An Underlying Fund may invest in shares of ETFs that are advised by BFA.

Short-Term Instruments and Temporary Investments. Each Fund and the Underlying Funds may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit, bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody's, “F-1” by Fitch, or “A-1” by S&P Global Ratings, or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions. See Risks of the Underlying Funds below.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on a pre-determined underlying investment or notional amount. In return, the other party agrees to make periodic payments to the first party based on the return (or a differential in rate of return) earned or realized on the underlying investment or notional amount. Swap agreements will usually be performed on a net basis, with each Underlying Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of an Underlying Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis.

Certain of the Funds or Underlying Funds may enter into currency swaps, interest rate swaps and index swaps. The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

U.S. Government Obligations. The Funds or an Underlying Fund may invest in various types of U.S. government obligations. U.S. government obligations are a type of bond and include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities. Payment of principal and interest on U.S. government obligations (i) may be backed by the full faith and credit of the U.S. or (ii) may be backed solely by the issuing or guaranteeing agency or instrumentality itself (as with Fannie Mae, Freddie Mac and FHLB notes). In the latter case, each Fund or an Underlying Fund must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. As a general matter, the value of debt instruments, including U.S. government obligations, declines when market interest rates increase and rises when market interest rates decrease. Certain types of U.S. government obligations are subject to fluctuations in yield or value due to their structure or contract terms.

Future Developments. The board of each Fund or Underlying Fund may, in the future, authorize each Underlying Fund to invest in securities contracts and investments, other than those listed in this SAI and in the applicable Prospectuses, provided they are consistent with each Fund's or Underlying Fund's investment objective and do not violate any of its investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in a Fund is contained in the applicable Prospectus. Because each Fund expects to obtain its exposure to the securities in the Underlying Index substantially through its investment in the Underlying Funds, shareholders should be aware that the risks of investment in particular types of securities, economic sectors and geographic locations discussed below may be borne by the Fund through its investment in the Underlying Funds. Through its investment in the Underlying Funds, each Fund will also bear the risks described below associated with the Underlying Funds' use of portfolio management techniques, such as borrowing arrangements and use of derivatives, in addition to the risks associated with those activities if the Funds engage in them directly.

An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities, including its investment in the Underlying Funds, may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market. The order of the below risk factors does not indicate the significance of any particular risk factor.

Borrowing Risk. Borrowing may exaggerate changes in the NAV of Fund shares and in the return on a Fund’s portfolio. Borrowing will cause a Fund to incur interest expense and other fees. The costs of borrowing may reduce a Fund’s return. Borrowing may cause a Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Funds or an Underlying Fund may “call” or repay the security before its stated maturity, and a Fund or an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in income, or in securities with greater risks or with other less favorable features.

Commodities Investment Risk. Exposure to commodities markets may subject a Fund or an Underlying Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in a Fund’s or Underlying Fund's holdings.

The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity investment prices are outside of a Fund's or Underlying Fund's control and may not be anticipated by BFA. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions, including droughts and floods; livestock disease; changing supply and demand relationships and levels of domestic production and imported commodities; changes in storage costs; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; and changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted.

The prices of commodities can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Certain commodities or natural resources may be produced in a limited number of countries and may be controlled by a small number of producers or groups of producers. As a result, political, economic, regulatory and supply-related events in such countries could have a disproportionate impact on the prices of such commodities.

A decrease in the production of a physical commodity or a decrease in the volume of such commodity available for transportation, mining, processing, storage or distribution may adversely impact the financial performance of a commodity or commodity-related company that devotes a portion of its business to that commodity. Production declines and volume decreases could be caused by various factors, including catastrophic events affecting production, depletion of resources, labor difficulties, environmental proceedings, increased regulations, equipment failures and unexpected maintenance problems, import supply disruption, governmental expropriation, political upheaval or conflicts or increased competition from alternative energy sources or commodity prices. Agricultural commodities may be adversely affected by weather or other natural phenomena, such as drought, floods and pests.

A sustained decline in demand for such commodities could also adversely affect the financial performance of commodity-related companies. Factors that could lead to a decline in demand include economic recession or other adverse economic conditions, higher taxes on commodities or increased governmental regulations, increases in fuel economy, consumer shifts to the use of alternative commodities or fuel sources, changes in commodity prices, or weather.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices which may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and to the holding of securities, cash and other assets by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets, and thus may be subject to limited or no government oversight. Communications between the U.S. and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because of the use of brokers and counterparties that are often less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence or undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on a Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. Each Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.

Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in a Fund’s or Underlying Fund's income and potentially in the value of a Fund’s or Underlying Fund's investments.

Illiquid Investments Risk. Each Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. The liquidity of an investment will be determined based on relevant market, trading and investment specific considerations as set out in the Liquidity Program as required by the Liquidity Rule. Illiquid investments may trade at a discount to comparable, more liquid investments and a Fund may not be able to dispose of illiquid investments in a timely fashion or at their expected prices. If illiquid investments exceed 15% of a Fund’s net assets, the Liquidity Rule and the Liquidity Program will require that certain remedial actions be taken.

Money Market Instruments Risk. A Fund or an Underlying Fund may hold money market instruments. The value of money market instruments may be affected by changes in interest rates or in the credit ratings of the investments, among other things. If a significant amount of a Fund's assets is invested in money market instruments, it may be more difficult for the Fund to achieve its investment objective. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than U.S. government money market funds and retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

Operational Risk. BFA and a Fund's other service providers may experience disruptions or operating errors such as processing errors or human errors, inadequate or failed internal or external processes, or systems or technology failures, that could negatively impact the Funds. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from a Fund’s in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. BFA, through its monitoring and oversight of service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for BFA or the other Fund service providers to identify all of the operational risks that may affect a Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause a Fund or an Underlying Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s or Underlying Fund's income or return potential. Also, if a security subject to prepayment had been purchased at a premium, the value of the premium would be lost in the event of prepayment.

Quasi-Sovereign Obligations Risk. An investment in quasi-sovereign debt obligations involves special risks generally not present in corporate debt obligations. Quasi-sovereign debt includes investments in securities issued or guaranteed by an entity affiliated with or backed by a sovereign government. Generally, quasi-sovereign debt obligations are issued by companies in which a government owns a majority of the issuer’s voting shares. They are often considered strategically important to the sovereign entity but do not legally carry sovereign status for purposes of debt repayment. While certain quasi-sovereign debt issuers have received sovereign government support in the past, such past support is not a guarantee that it will continue in the future. In fact, in the past certain quasi-sovereign debt issuers have pushed their creditors toward debt restructuring, rather than meeting their payment obligations. Quasi-sovereign debt obligations are typically less liquid and less standardized than sovereign debt obligations.

Reference Rate Replacement Risk. A Fund or an Underlying Fund may be exposed to financial instruments that recently transitioned from, or continue to be tied to, the London Interbank Offered Rate (“LIBOR”) to determine payment obligations, financing terms, hedging strategies or investment value. The United Kingdom’s Financial Conduct Authority (“FCA”), which regulates LIBOR, has ceased publishing all LIBOR settings. In April 2023, however, the FCA announced that some USD LIBOR settings will continue to be published under a synthetic methodology until September 30, 2024 for certain legacy contracts. The Secured Overnight Financing Rate (“SOFR”), which is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement market, has been used increasingly on a voluntary basis in new instruments and transactions. Under U.S. regulations that implement a statutory fallback mechanism to replace LIBOR, benchmark rates based on SOFR have replaced LIBOR in different categories of financial contracts.

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities, or other instruments using LIBOR may disagree on transition rates or the application of transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. A Fund or an Underlying Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

Risk of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500 or the prime lending rate). The Funds and certain Underlying Funds may invest in stock index futures contracts, securities options and other derivatives. Compared to securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund's or an Underlying Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage.

When a derivative is used as a hedge against a position that a Fund holds or is committed to purchase, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains, and in some cases, hedging can cause losses that are not offset by gains, and the Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that a Fund’s hedging transactions, which entail additional transaction costs, will be effective.

Risks of Equity Securities. An investment in a Fund should be made with an understanding that the value of an Underlying Fund's portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of preferred or common stocks in general and other factors that affect the market. An investment in a Fund should also be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of an Underlying Fund). Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction and global or regional political, economic or banking crises. Holders of common stocks incur more risk than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from the issuer inferior to the rights of creditors or holders of debt obligations or preferred stocks. Further, unlike debt securities which typically have a stated principal amount payable at maturity (whose value, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity.

Risk of Futures and Options on Futures Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While each Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Futures contracts, by definition, project price levels in the future and not current levels of valuation; therefore, market circumstances may result in a discrepancy between the price of the future and the movement in a Fund's Underlying Index. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if a Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to deliver the instruments underlying the futures contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Funds do not plan to use futures and options contracts in this way. The risk of

a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Funds, however, intend to utilize futures and options contracts in a manner designed to limit their risk exposure to levels comparable to a direct investment in the types of stocks in which they invest.

Utilization of futures and options on futures by a Fund involves the risk of imperfect or even negative correlation to the Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss of margin deposits in the event of bankruptcy of a broker with whom a Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting each Fund to substantial losses. In the event of adverse price movements, each Fund would be required to make daily cash payments of variation margin.

Risk of Investing in Non-U.S. Debt Securities. Non-U.S. debt securities are traded on foreign exchanges and OTC in the respective countries covered by a Fund or an Underlying Fund. The risks of investing in non-U.S. debt securities typically include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in bond prices. Investing in a fund whose portfolio contains securities of non-U.S. issuers involves certain risks and considerations not typically associated with investing in the securities of U.S. issuers. These risks include securities markets that may lack sufficient liquidity or may be less efficient; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of a Fund or an Underlying Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization of most non-U.S. securities markets; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and different bankruptcy and insolvency regimes which may stay or prevent recovery in the event of an issuer’s default.

Risk of Investing in Non-U.S. Equity Securities. An investment in non-U.S. equity securities involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments in those foreign countries, changes in interest rates and perceived trends in stock prices.

Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Because certain Underlying Funds invest in non-U.S. equity securities, investing in any of the Funds also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Underlying Funds; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy and businesses; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risk of Swap Agreements. The risk of loss with respect to swaps is generally limited to the net amount of payments that a Fund or an Underlying Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, a Fund or an Underlying Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws, which could affect such Fund’s or Underlying Fund's rights as a creditor (e.g., a Fund or an Underlying Fund may not receive the net amount of payments that it is contractually entitled to receive).

A Fund or an Underlying Fund is required to post and collect variation margin and initial margin (comprised of specified liquid securities subject to haircuts) in connection with trading of OTC swaps. These requirements may raise the costs for a Fund’s or an Underlying Fund's investment in swaps.

Tracking Error Risk. A Fund or each of its Underlying Funds may be subject to tracking error, which is the divergence of a fund’s performance from that of its underlying index. Tracking error may occur because of differences between the securities and other instruments held in a fund’s portfolio and those included in a Fund’s Underling Index or an Underlying Fund's underlying index, pricing differences, transaction costs incurred by a Fund or its Underlying Funds, a Fund’s or its Underlying Funds' holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest received by a Fund or distributions paid to a Fund’s or an Underlying Fund's shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or an Underlying Fund’s underlying index or the costs to a Fund or an Underlying Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because a fund incurs fees and expenses, while such a fund's underlying index does not.

When an issuer is introduced by an index provider into an index tracked by a Fund or its Underlying Funds, BFA may conduct an analysis on such issuer’s securities to identify and screen for outlier high risk behavior (such as rapid or unusual price growth that does not appear to be supported by publicly available information on the business and assets of the issuer, unusual or significant short interest or lending activity, negative sentiment, suspended trading or incorrect free-float calculations, which could be indicators of possible irregularities, miscalculations or even fraud). If it identifies such behavior, BFA may, where appropriate, alert the index provider as to the alleged issue. The index provider has sole discretion for the determination as to whether to continue to include the issuer’s securities in the rebalancing of its index. If the securities continue to be included in the index, BFA may underweight or exclude such securities from a Fund’s or an Underlying Fund's portfolio and, if it does so, such a fund will be subject to increased tracking error due to the divergence in the securities included in its portfolio from its underlying index. BFA’s underweighting or excluding such securities may result in a decline in a Fund’s net asset value. The application of the abovementioned analysis and screening to a Fund or an Underlying Fund and its Underlying Index is in the sole discretion of BFA and its affiliates (without any guarantees). The analysis and screening may not exclude any or all high risk securities from an Underlying Index or a Fund’s or an Underlying Fund's portfolio, and the inclusion of such securities will result in an adverse impact to a Fund’s net asset value if one or more such securities declines in value.

U.S. Agency Mortgage-Backed Securities Risk. Securities backed by pools of mortgages issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, including Government National Mortgage Association (“Ginnie Mae”), Federal National Mortgage Association (“Fannie Mae”), and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The market for mortgage-backed securities (“MBS”) has been adversely affected by the value of those MBS held and/or issued by these agencies and sponsored entities. If a U.S. government agency or sponsored entity issues securities in which the Funds invest and such issuer is unable to meet its obligations or ceases to exist, and no plan is made for the repayment of securities, the performance of the Funds will be adversely impacted.

Ginnie Mae. Established in 1968, Ginnie Mae is a wholly owned U.S. government corporation within the U.S. Department of Housing and Urban Development. Ginnie Mae is authorized to guarantee, with the backing of the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by the institutions approved by Ginnie Mae (such as savings and loan institutions, commercial banks and mortgage banks), and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the U.S. Department of Veterans Affairs. Ginnie Mae securities also are supported by the authority of Ginnie Mae to borrow funds from the U.S. Treasury Department to make payments under its guarantee. Any actual or potential disruption to Ginnie Mae, or the financial condition or credit of the U.S. government, could cause the value of Ginnie Mae securities to decline. In 2011, S&P Global Ratings downgraded U.S. Treasury securities from AAA rating to AA+ rating. A further downgrade of the ratings of U.S. government debt obligations, which are often used

as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade below AA+ rating by S&P Global Ratings may cause the value of Ginnie Mae securities to decline.

Fannie Mae and Freddie Mac. Fannie Mae was established as a federal agency in 1938 and in 1968 was chartered by Congress as a private shareholder-owned company. Securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae. The securities are not backed by or entitled to the full faith and credit of the U.S. government, but are supported by the right of Fannie Mae to borrow from the U.S. Treasury Department.

Freddie Mac is a stockholder-owned corporation chartered by Congress in 1970. Securities issued by Freddie Mac entitle the holder to timely payment of interests, which is guaranteed by Freddie Mac. Freddie Mac also guarantees either ultimate collection or timely payment of all principal payments. While Freddie Mac generally does not guarantee timely payment of principal, Freddie Mac may remit the amount due on account of its guarantee of ultimate payment of principal at any time after default on an underlying mortgage, but in no event later than one year after it becomes payable. The securities are not backed by or entitled to the full faith and credit of the U.S. government or by any Federal Home Loan Banks, but are supported by the right of Freddie Mac to borrow from the U.S. Treasury Department.

In 2008, the Federal Housing Finance Agency placed each of Fannie Mae and Freddie Mac into government conservatorship in an effort to provide stability in the financial markets and put the government-sponsored entities in sound and solvent condition. In addition, the U.S. Treasury Department agreed to provide Fannie Mae and Freddie Mac up to $100 billion of capital each on an as needed basis to ensure that they continue to provide liquidity to the housing and mortgage markets.

Mortgage-Backed Securities. MBS issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, such as Ginnie Mae, Fannie Mae, or Freddie Mac, represent interests in pools of mortgages in which payments of both principal and interest on the securities are generally made monthly, in effect “passing through” the payments made by borrowers on the mortgage loans that underlie the securities (net of any fees paid to the issuer or guarantor of the securities). MBS differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates, while a MBS payments provide a combination of interest and principal throughout the a bond’s term. As further described below, MBS may be structured as pass-through securities or collateralized mortgage obligations (“CMOs”).

MBS are subject to the general risks associated with investing in real estate securities; that is, they may lose value if the value of the underlying real estate to which a pool of mortgages relates declines. In addition, investments in MBS involve certain specific risks. These risks include the failure of a party to meet its commitments under the related operative documents, adverse interest rate changes and the effects of prepayments on mortgage cash flows. The value of MBS, like that of traditional fixed-income securities, typically increases when interest rates fall and decreases when interest rates rise. However, MBS differ from traditional fixed-income securities because of their potential for prepayment without penalty. The price paid by a Fund for its MBS, the yield a Fund expects to receive from such securities and the weighted average life of the securities are based on a number of factors, including the anticipated rate of prepayment of the underlying mortgages. In a period of declining interest rates, borrowers may prepay the underlying mortgages more quickly than anticipated, thereby reducing the yield to maturity and the average life of the MBS. Moreover, when a Fund reinvests the proceeds of a prepayment in these circumstances, it will likely receive a rate of interest that is lower than the rate on the security that was prepaid.

To the extent that a Fund purchases MBS at a premium, mortgage foreclosures and principal prepayments may result in a loss to the extent of the premium paid. If a Fund buys such securities at a discount, both scheduled payments of principal and unscheduled prepayments will increase current and total returns and will accelerate the recognition of income, which, when distributed to shareholders, will be taxable as ordinary income. In a period of rising interest rates, prepayments of the underlying mortgages may occur at a slower than expected rate, creating maturity extension risk. This particular risk may effectively change a security that was considered short- or intermediate-term at the time of purchase into a long-term security. Since the value of long-term securities generally fluctuates more widely in response to changes in interest rates than that of shorter-term securities, maturity extension risk could increase the inherent volatility of a Fund. Under certain interest rate and prepayment scenarios, a Fund may fail to recoup fully its investment in MBS notwithstanding any direct or indirect U.S. governmental or agency guarantee.

Mortgage Pass-Through Securities. Some MBS, such as U.S. agency mortgage pass-through securities, represent a right to receive principal and interest payments collected on a pool of mortgages, which are passed through to security holders. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of mortgage pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of MBS is difficult to predict and can impact the subsequent cash flows, value and yield of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction.

To-Be-Announced Securities. A Fund may seek to gain exposure to U.S. agency mortgage pass-through securities by investing in TBA securities. “TBAs” refer to a commonly used mechanism for the forward settlement of U.S. agency MBS, and not to a separate type of MBS. Most transactions in fixed-rate MBS occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement, and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as the issuing agency, settlement date, par amount, and price. The actual mortgage pools delivered generally are determined two days prior to settlement date. The Funds may regularly enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a TBA roll, such Funds generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will enter into a new TBA agreement for future delivery of pools of MBS. In addition, the Funds may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of MBS stipulated in the TBA agreement.

Certain of the Funds and Underlying Funds intend to invest cash pending settlement of TBA transactions in money market instruments, repurchase agreements, or other high quality, liquid short-term instruments, including money market funds advised by BFA. Certain of the Funds and Underlying Funds will pay their pro rata share of fees and expenses of any money market fund that it may invest in, in addition to the Funds and Underlying Fund’s own fees and expenses.

Collateralized Mortgage Obligations. U.S. agency MBS may also be structured in the form of CMOs. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (“tranches”) with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches may represent a right to receive interest only, principal only, or an amount that remains after floating-rate tranches are paid (an “inverse floater”). These securities are frequently referred to as “mortgage derivatives” and may be extremely sensitive to changes in interest rates. Interest rates on inverse floaters, for example, vary inversely with a short-term floating rate (which may be reset periodically). Interest rates on inverse floaters will decrease when short-term rates increase and will increase when short-term rates decrease. These securities have the effect of providing a degree of investment leverage. In response to changes in market interest rates or other market conditions, the value of an inverse floater may increase or decrease at a multiple of the increase or decrease in the value of the underlying securities. If a Fund invests in CMO tranches issued by U.S. government agencies or sponsored entities and interest rates move in a manner not anticipated by BFA, it is possible that such a Fund could lose all or substantially all of its investment. Certain CMOs in which the Funds may invest may also provide a degree of investment leverage, which could cause such a Fund to lose all or substantially all of its investment.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of a Fund's U.S. Treasury obligations to decline. U.S. Treasury securities are rated AA+ by S&P Global Ratings. A downgrade of the rating of U.S. Treasury securities may cause the value of a Fund's U.S. Treasury obligations to decline. Because U.S. government debt obligations are often used as a benchmark for other borrowing arrangements, a downgrade could also result in higher interest rates for a range of borrowers, cause disruptions in the international bond markets and have a substantial adverse effect on the U.S. and global economy.

A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and lead the government to issue additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that the U.S. government will not be able to make principal or interest payments when they are due. If market

participants determine that U.S. sovereign debt levels have become unsustainable, the value of the U.S. dollar could decline, thus increasing inflationary pressures, particularly with respect to services outsourced to non-U.S. providers and imported goods and constrain or prevent the U.S. government from implementing effective countercyclical fiscal policy in economic downturns. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period that shareholders own shares of a Fund. Notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the U.S., circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative “debt ceiling.” Such non-payment would result in losses to a Fund and substantial negative consequences for the U.S. economy and the global financial system.

Risk of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in other regions. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, piracy of intellectual property, data and other security breaches (especially of data stored electronically), political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest. Certain Asian economies have experienced rapid rates of economic growth and industrialization in recent years, and there is no assurance that these rates of economic growth and industrialization will be maintained.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Certain Asian countries have also developed increasingly strained relationships with the U.S., and if these relations were to worsen, they could adversely affect Asian issuers that rely on the U.S. for trade. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. China is a key trading partner of many Asian countries and any changes in trading relationships between China and other Asian countries may affect the region as a whole. Adverse economic conditions or developments in neighboring countries may increase investors' perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risk of Investing in Australasia. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service and tourism industries. Australia and New Zealand are located in a part of the world that has historically been prone to natural disasters, such as drought and flooding. Any such event in the future could have a significant adverse impact on the economies of Australia and New Zealand and affect the value of securities held by the relevant Underlying Funds. The economies of Australia and New Zealand are dependent on trading with certain key trading partners, including Asia and the U.S. The

economies of Australia and New Zealand are heavily dependent on the mining sector. Passage of new regulations limiting foreign ownership of companies in the mining sector or imposition of new taxes on profits of mining companies may dissuade foreign investment, and as a result, have a negative impact on companies to which the Underlying Funds have exposure.

Risk of Investing in China. Investments in securities of companies domiciled in China involve a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, an authoritarian government, popular unrest associated with demands for improved political, economic and social conditions, the impact of regional conflict on the economy and hostile relations with neighboring countries.

Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. The Chinese economy is vulnerable to the long-running disagreements and religious and nationalist disputes with Tibet and the Xinjiang region. Since 1997, there have been tensions between the Chinese government and many people in Hong Kong who perceive China as tightening control over Hong Kong’s semi-autonomous liberal political, economic, legal, and social framework. Recent protests and unrest have increased tensions even further. Due to the interconnected nature of the Hong Kong and Chinese economies, this instability in Hong Kong may cause uncertainty in the Hong Kong and Chinese markets. China has a complex territorial dispute regarding the sovereignty of Taiwan and has made threats of invasion. Taiwan-based companies and individuals are significant investors in China. Military conflict between China and Taiwan may adversely affect securities of Chinese issuers. In addition, China has strained international relations with Japan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which an Underlying Fund invests. China could be affected by military events on the Korean peninsula or internal instability within North Korea. These situations may cause uncertainty in the Chinese market and may adversely affect the performance of the Chinese economy.

The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. However, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. Chinese companies, such as those in the financial services or technology sectors, and potentially other sectors in the future, are subject to the risk that Chinese authorities can intervene in their operations and structure. The Chinese government continues to maintain a major role in economic policymaking, and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

A Fund may invest in securities issued by variable interest entities (“VIEs”), which are subject to the investment risks associated with the underlying Chinese operating company. A VIE enters into service contracts and other contracts with the Chinese operating company, which provide the VIE with exposure to the company. Although the VIE has no equity ownership of the Chinese operating company, the contractual arrangements permit the VIE to consolidate the Chinese operating company into its financial statements. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company’s performance and the enforceability of the VIE’s contractual arrangements with the Chinese company.

In addition, there is less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the U.S. Accordingly, issuers of securities in China, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer regulation, accounting standards or auditor oversight, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Securities markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation.

There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies. The Funds are not actively managed and do not select investments based on investor protection considerations.

The Funds and the Underlying Funds may invest in H-shares (securities of companies incorporated in the People's Republic of China (“PRC”) that are denominated in Hong Kong dollars and listed on the Stock Exchange of Hong Kong Limited) and B-shares (securities of companies incorporated in the PRC and listed for foreign investment on stock exchanges in the PRC). The Funds and the Underlying Funds may also invest in certain Hong Kong listed securities known as Red-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by entities owned by the national government or local governments in the PRC and derive substantial revenues or allocate substantial assets in the PRC) and P-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by individuals in the PRC and derive substantial revenues or allocate substantial assets in the PRC). Securities listed on the Shanghai or Shenzhen stock exchanges are divided into two classes: A-Shares, which are mostly limited to domestic investors and denominated in renminbi, and B-shares, which are allocated for both international and domestic investors and denominated in U.S. dollars on the Shanghai exchange and Hong Kong dollars on the Shenzhen exchange. The B-shares market is generally smaller, less liquid and has a smaller issuer base than the A-Shares market, which may lead to significant price volatility. B-shares, H-shares, P-Chips or Red-Chips of issuers that also issue A-Shares may trade at significant discounts to their A-Shares counterparts. The issuance of B-shares and H-shares by Chinese companies and the ability to obtain a “back-door listing” through Red-Chips or P-Chips is still regarded by the Chinese authorities as an experiment in economic reform. “Back-door listing” is a means by which a mainland Chinese company issues Red-Chips or P-Chips to obtain quick access to international listing and international capital. All of these share mechanisms are relatively untested and subject to political and economic policy in China. Chinese securities have recently experienced substantial volatility, which is expected to continue in the future. Chinese exchanges on which local China A shares are listed impose daily price limits on trading of stocks and mutual funds. The Shanghai Stock Exchange, for example, imposes a daily price up/down limit based on a fixed percentage of the price of common stocks, subject to adjustment with regulatory approval. Local exchange rules may also allow issuers to suspend their shares' trading for a variety of reasons. These and other factors may make it difficult to acquire, dispose of, or value shares of Chinese issuers, which could lead to adverse effects to the Funds.

While the Chinese economy has experienced past periods of rapid growth, there is no assurance that such growth rates will recur. China may experience substantial rates of inflation, significant indebtedness or economic recessions, causing a negative effect on the economy and securities market. China’s economy is heavily dependent on export growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs, sanctions or other trade barriers (including as a result of heightened trade tensions between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy and the companies in which a Fund invests. Certain Chinese companies (which may change from time to time) are directly or indirectly subject to economic or trade restrictions imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. For example, certain foreign technology companies are subject to U.S. export controls as those companies are believed to pose a risk to U.S. interests. The U.S. also bans imports of goods produced in certain regions of China or by certain Chinese companies due to concerns about forced labor. Such restrictions may have unanticipated and adverse effects on the Chinese economy and companies. Any action that targets Chinese financial markets or securities exchanges could interfere with orderly trading, delay settlement or cause market disruptions. The Underlying Index of a Fund may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies, consistent with its objective to track the performance of its Underlying Index.

The tax laws and regulations in the People’s Republic of China (“PRC”) are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to region. The application and enforcement of PRC tax rules could have a significant adverse effect on a Fund or an Underlying Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents. In addition, the accounting, auditing and financial reporting standards and practices applicable to Chinese companies may be less rigorous, and may result in significant differences between financial statements prepared in accordance with the PRC accounting standards and practice and those prepared in accordance with international accounting standards.

Risk of Investing in Developed Countries. Many countries with developed markets have recently experienced significant economic pressures. These countries generally tend to rely on the services sectors (e.g., the financial services sector) as the primary source of economic growth and may be susceptible to the risks of individual service sectors. For example, companies

in the financial services sector are subject to governmental regulation and, recently, government intervention, which may adversely affect the scope of their activities, the prices they can charge and amount of capital they must maintain. Dislocations in the financial sector and perceived or actual governmental influence over certain financial companies may lead to credit rating downgrades and, as a result, impact, among other things, revenue growth for such companies. If financial companies experience a prolonged decline in revenue growth, certain developed countries that rely heavily on financial companies as an economic driver may experience a correlative slowdown. Concerns have emerged with respect to the economic health of certain developed countries. These concerns primarily stem from heavy indebtedness of many developed countries and their perceived inability to continue to service high debt loads without simultaneously implementing stringent austerity measures. Such concerns have led to tremendous downward pressure on the economies of these countries. As a result, it is possible that interest rates on debt of certain developed countries may rise to levels that make it difficult for such countries to service such debt. Spending on health care and retirement pensions in most developed countries has risen dramatically. Medical innovation, extended life expectancy and higher public expectations are likely to continue the increase in health care and pension costs. Any increase in health care and pension costs will likely have a negative impact on the economic growth of many developed countries. Certain developed countries rely on imports of certain key items, such as crude oil, natural gas, and other commodities. As a result, an increase in demand for, or price fluctuations of, certain commodities may negatively affect developed country economies. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries. In addition, heavy regulation of, among others, labor and product markets may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Such risks, among others, may adversely affect the value of a Fund’s or an Underlying Fund's investments.

Risk of Investing in Emerging Markets. Investments in emerging market countries may be subject to greater risks than investments in developed countries. These risks include: (i) less social, political, and economic stability; (ii) greater illiquidity and price volatility due to smaller or limited local capital markets for such securities, or low or non-existent trading volumes; (iii) companies, custodians, clearinghouses, foreign exchanges and broker-dealers may be subject to less scrutiny and regulation by local authorities; (iv) local governments may decide to seize or confiscate securities held by foreign investors and/or local governments may decide to suspend or limit an issuer's ability to make dividend or interest payments; (v) local governments may limit or entirely restrict repatriation of invested capital, profits, and dividends; (vi) capital gains may be subject to local taxation, including on a retroactive basis; (vii) issuers facing restrictions on standard payments imposed by local governments may attempt to make dividend or interest payments to foreign investors in the local currency; (viii) there may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and investors may experience difficulty in enforcing legal claims related to the securities and/or local judges may favor the interests of the issuer over those of foreign parties; (ix) bankruptcy judgments may only be permitted to be paid in the local currency; (x) limited public information regarding the issuer may result in greater difficulty in determining market valuations of the securities; and (xi) lack of financial reporting on a regular basis, substandard disclosure and differences in accounting standards may make it difficult to ascertain the financial health of an issuer. The Funds are not actively managed and do not select investments based on investor protection considerations.

Emerging market securities markets are typically marked by a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of ownership of such securities by a limited number of investors. In addition, brokerage and other costs associated with transactions in emerging market securities can be higher, sometimes significantly, than similar costs incurred in securities markets in developed countries. Although some emerging markets have become more established and tend to issue securities of higher credit quality, the markets for securities in other emerging market countries are in the earliest stages of their development, and these countries issue securities across the credit spectrum. Even the markets for relatively widely traded securities in emerging market countries may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging market country securities may also affect an Underlying Fund's ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Many emerging market countries suffer from uncertainty and corruption in their legal frameworks. Legislation may be difficult to interpret and laws may be too new to provide any precedential value. Laws regarding foreign investment and

private property may be weak or non-existent. Sudden changes in governments may result in policies which are less favorable to investors such as policies designed to expropriate or nationalize “sovereign” assets. Certain emerging market countries in the past have expropriated large amounts of private property, in many cases with little or no compensation, and there can be no assurance that such expropriation will not occur in the future.

Investment in the securities markets of certain emerging market countries is restricted or controlled to varying degrees. These restrictions may limit an Underlying Fund's investment in certain emerging market countries and may increase the expenses of the Underlying Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons or limit investment by foreign persons to only a specified percentage of an issuer's outstanding securities or a specific class of securities which may have less advantageous terms (including price) than securities of the company available for purchase by nationals.

Many emerging market countries lack the social, political, and economic stability characteristic of the U.S. Political instability among emerging market countries can be common and may be caused by an uneven distribution of wealth, social unrest, labor strikes, civil wars, and religious oppression. Economic instability in emerging market countries may take the form of: (i) high interest rates; (ii) high levels of inflation, including hyperinflation; (iii) high levels of unemployment or underemployment; (iv) changes in government economic and tax policies, including confiscatory taxation; and (v) imposition of trade barriers.

An Underlying Fund's income and, in some cases, capital gains from foreign securities will be subject to applicable taxation in certain of the emerging market countries in which it invests, and treaties between the U.S. and such countries may not be available in some cases to reduce the otherwise applicable tax rates.

Emerging markets also have different clearance and settlement procedures, and in certain of these emerging markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions.

In the past, certain governments in emerging market countries have become overly reliant on the international capital markets and other forms of foreign credit to finance large public spending programs, which in the past have caused huge budget deficits. Often, interest payments have become too overwhelming for a government to meet, representing a large percentage of total GDP. These foreign obligations have become the subject of political debate and served as fuel for political parties of the opposition, which pressure the government not to make payments to foreign creditors, but instead to use these funds for, among other things, social programs. Either due to an inability to pay or submission to political pressure, foreign governments have been forced to seek a restructuring of their loan and/or bond obligations, have declared a temporary suspension of interest payments or have defaulted. These events have adversely affected the values of securities issued by foreign governments and corporations domiciled in those countries and have negatively affected not only their cost of borrowing, but their ability to borrow in the future as well.

Risk of Investing in Europe. Investing in European countries may expose an Underlying Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. An Underlying Fund makes investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and their trading partners. Although certain European countries are not in the eurozone, many of these countries are obliged to meet the criteria for joining the eurozone.

Consequently, these countries must comply with many of the restrictions noted above. The European financial markets have experienced volatility and adverse trends due to concerns about economic downturns, government debt levels and the possible default of government debt in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. In order to prevent further economic deterioration, certain

countries, without prior warning, can institute “capital controls.” Countries may use these controls to restrict volatile movements of capital entering and exiting their country. Such controls may negatively affect an Underlying Fund’s investments. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed above. In addition, the credit ratings of certain European countries were downgraded in the past. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member states. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching and could adversely impact the value of an Underlying Fund’s investments in the region.

The United Kingdom (the “U.K.”) left the EU (“Brexit”) on January 31, 2020. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.

Certain European countries have also developed increasingly strained relationships with the U.S., and if these relations were to worsen, they could adversely affect European issuers that rely on the U.S. for trade. The national politics of countries in Europe have been unpredictable and subject to influence by disruptive political groups and ideologies, including for example, secessionist movements. The governments of European countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe or war in the region also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's or Underlying Fund's investments.

Russian Invasion of Ukraine. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, may impact Russia's economy, Russian issuers of securities in which a Fund invests, or the economies of Europe as a whole. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors across Europe and globally.

Risk of Investing in Japan. Japan may be subject to political, economic, labor and other risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the Japanese economy. Japan has, in the past, intervened in the currency markets to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors.

Economic Risk. The growth of Japan’s economy has recently lagged that of its Asian neighbors and other major developed economies. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. Japan is also heavily dependent on oil imports, and higher commodity prices could therefore have a negative impact on the Japanese economy.

Geographic Risk. Natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect a Fund.

Labor Risk. Japan has an aging workforce and has experienced a significant population decline in recent years. Japan’s labor market appears to be undergoing fundamental structural changes, as a labor market traditionally accustomed to lifetime employment adjusts to meet the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.

Large Government and Corporate Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect an Underlying Fund’s investments. In addition, China has become an important trading partner with Japan. Japan’s political relationship with China, however, has been strained. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Funds) to invest in the securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. In addition, the Capital Market Authority (“CMA”) places investment limitations on the ownership of the securities of Saudi Arabian issuers by foreign investors, including a limitation on an Underlying Fund’s ownership of the securities of any single issuer listed on the Saudi Arabian Stock Exchange, which may prevent an Underlying Fund from investing in accordance with its strategy and contribute to tracking error against the Underlying Index. These restrictions may be changed or new restrictions, such as licensing requirements, special approvals or additional foreign taxes, may be instituted at any time. A Fund may not be able to obtain or maintain any such licenses or approvals and may not be able to buy and sell securities at full value. Major disruptions or regulatory changes could occur in the Saudi Arabian market, any of which could negatively impact an Underlying Fund. These risks may be exacerbated, compared to more developed markets, given the limited history of foreign investment in the Saudi Arabian market. Investments in Saudi Arabia may also be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on additional foreign investments and repatriation of capital. Such heightened risks may include, among others, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. Saudi Arabia has privatized, or has begun the process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur. Saudi Arabia is highly reliant on income from the sale of petroleum and trade with other countries involved in the sale of petroleum, and its economy is therefore vulnerable to changes in foreign currency values and the market for petroleum, as well as acts targeting petroleum production or processing facilities in Saudi Arabia. As global demand for petroleum fluctuates, Saudi Arabia may be significantly impacted. In the recent past, the Saudi Arabian government has explored privatization and diversification of the economy in the wake of a diminished petroleum market.

Like most Middle Eastern governments, the government of Saudi Arabia exercises substantial influence over many aspects of the private sector. Although liberalization in the wider economy is underway, in many areas it has lagged significantly: restrictions on foreign ownership persist, and the government has an ownership stake in many key industries. The situation is exacerbated by the fact that Saudi Arabia is governed by an absolute monarchy. Saudi Arabia has historically experienced strained relations with economic partners worldwide, including other countries in the Middle East, due to geopolitical events. Incidents involving a Middle Eastern country’s or the region’s security, including terrorism, may cause uncertainty in their markets and may adversely affect its economy and an Underlying Fund’s investments.

Governmental actions in the future could have a significant effect on economic conditions in Saudi Arabia, which could affect private sector companies and an Underlying Fund, as well as the value of securities in an Underlying Fund’s portfolio. Any economic sanctions on Saudi Arabian individuals or Saudi Arabian corporate entities, or even the threat of sanctions, may result in the decline of the value and liquidity of Saudi Arabian securities, a weakening of the Saudi riyal or other adverse consequences to the Saudi Arabian economy. Any sanctions could also result in the immediate freeze of Saudi Arabian

securities and/or funds investing in prohibited assets, impairing the ability of an Underlying Fund to buy, sell, receive or deliver those securities and/or assets. In addition, Saudi Arabia’s economy relies heavily on cheap, foreign labor, and changes in the availability of this labor supply could have an adverse effect on the economy.

The securities markets in Saudi Arabia may not be as developed as those in other countries. As a result, securities markets in Saudi Arabia are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations, uncertainty regarding the existence of trading markets, governmental control and heavy regulation of labor and industry. Shares of certain Saudi Arabian companies tend to trade less frequently than those of companies on exchanges in more developed markets. Such infrequent trading may adversely affect the pricing of these securities and an Underlying Fund’s ability to sell these securities in the future.

Although the political situation in Saudi Arabia is largely stable, Saudi Arabia has historically experienced political instability, and there remains the possibility that the stability will not hold in the future or that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia. Instability may be caused by military developments, government interventions in the marketplace, terrorism, extremist attitudes, attempted social or political reforms, religious differences, or other factors. Additionally, anti-Western views held by certain groups in the Middle East may influence government policies regarding foreign investment. Further developments in U.S. relations with Saudi Arabia and other Middle-Eastern countries may affect these attitudes and policies. The U.S. is a significant trading partner of, or foreign investor in, Saudi Arabia. As a result, economic conditions of Saudi Arabia may be particularly affected by changes in the U.S. economy. A decrease in U.S. imports or exports, new trade and financial regulations or tariffs, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economic conditions of Saudi Arabia and, as a result, securities to which an Underlying Fund has exposure. Political instability in North Africa and the larger Middle East region has caused significant disruptions to many industries. Continued political and social unrest in these areas may negatively affect the value of securities in an Underlying Fund’s portfolio.

Certain issuers located in Saudi Arabia may operate in, or have dealings with, countries subject to sanctions and/or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. As a result, an issuer may sustain damage to its reputation if it is identified as an issuer which operates in, or has dealings with, such countries. An Underlying Fund, as an investor in such issuers, will be indirectly subject to those risks.

Risk of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The success of these companies can depend heavily on disposable household income and consumer spending. During periods of an expanding economy, the consumer discretionary sector may outperform the consumer staples sector, but may underperform when economic conditions worsen. Moreover, the consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer preferences, demographics, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risk of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumer staples sector may also be affected by changes in global economic, environmental and political events, economic conditions, the depletion of resources, and government regulation. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Companies in the consumer staples sector also may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions. Companies in the consumer staples sector may be subject to severe competition, which may also have an adverse impact on their profitability.

Risk of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation efforts, technological change, development of alternative energy sources, and other factors that they cannot control. These companies may also lack resources and have limited business lines. Energy companies may have relatively high levels of debt and may be more likely to restructure their businesses if there are downturns in certain energy markets or in the global economy. If an energy company in an Underlying Fund's portfolio becomes distressed, an Underlying Fund could lose all or a substantial portion of its investment.

The energy sector is cyclical and is highly dependent on commodity prices; prices and supplies of energy may fluctuate significantly over short and long periods of time due to, among other things, national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. Commodity prices have recently been subject to increased volatility and declines, which may negatively affect companies in which an Underlying Fund invests. For example, in the context of the COVID-19 outbreak and disputes among oil-producing countries regarding potential limits on the production of crude oil, the energy sector has experienced increased volatility. In particular, significant market volatility occurred and is continuing in the crude oil markets as well as the oil futures markets, which resulted in the market price of the front month futures contract falling below zero for a period of time.

Companies in the energy sector may be adversely affected by terrorism, natural disasters or other catastrophes. While the Fund seeks to invest in companies with positive or favorable environmental and social characteristics, companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. Significant oil and gas deposits are located in emerging markets countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. Additionally, the Middle East, where many companies in the energy sector may operate, has historically and recently experienced widespread social unrest.

Companies in the energy sector may also be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, government regulation and intervention, negative perception, efforts at energy conservation and world events in the regions in which the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Because a significant portion of revenues of companies in this sector is derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this sector. The energy sector is highly regulated. Entities operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by governmental agencies. Such regulation can change rapidly or over time in both scope and intensity. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may materially adversely affect the financial performance of companies in the energy sector.

Risk of Investing in the Financials Sector. Companies in the financials sector include small, regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, consumer finance firms, financial conglomerates and foreign banking and financial companies.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which an Underlying Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market-specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include

taxes and controls on interest rates, credit availability, minimum capital requirements, bans on short sales, limits on prices and restrictions on currency transfers. In addition, companies in the financials sector may be the targets of hacking and potential theft of proprietary or customer information or disruptions in service, which could have a material adverse effect on their businesses.

The profitability of banks, savings and loan associations and other financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change; for instance, when interest rates go up, the value of securities issued by many types of companies in the financials sector generally goes down. In other words, financial companies may be adversely affected in certain market cycles, including, without limitation, during periods of rising interest rates, which may restrict the availability and increase the cost of capital, and during periods of declining economic conditions, which may cause, among other things, credit losses due to financial difficulties of borrowers.

In addition, general economic conditions are important to the operations of these companies, and financial difficulties of borrowers may have an adverse effect on the profitability of financial companies. Companies in the financials sector are exposed directly to the credit risk of their borrowers and counterparties, who may be leveraged to an unknown degree, including through swaps and other derivatives products, and who at times may be unable to meet their obligations to the financial services companies. Financial services companies may have significant exposure to the same borrowers and counterparties, with the result that a borrower’s or counterparty’s inability to meet its obligations to one company may affect other companies with exposure to the same borrower or counterparty. This interconnectedness of risk, including cross-default risk, may result in significant negative impacts to the financial condition and reputation of companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financials sector generally. Financial companies can be highly dependent upon access to capital markets, and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business. Deterioration of credit markets can have an adverse impact on a broad range of financial markets, causing certain financial companies to incur large losses. In these conditions, companies in the financials sector may experience significant declines in the valuation of their assets, take actions to raise capital and even cease operations. Some financial companies may also be required to accept or borrow significant amounts of capital from government sources and may face future government-imposed restrictions on their businesses or increased government intervention. In addition, there is no guarantee that governments will provide any such relief in the future. These actions may cause the securities of many companies in the financials sector to decline in value.

Risk of Investing in the Healthcare Sector. Companies in the healthcare sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, a limited number of products, industry innovation, changes in technologies and other market developments. Many healthcare companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products.

Patents have a limited duration, and, upon expiration, other companies may market substantially similar “generic” products that are typically sold at a lower price than the patented product, which can cause the original developer of the product to lose market share and/or reduce the price charged for the product, resulting in lower profits for the original developer. As a result, the expiration of patents may adversely affect the profitability of these companies.

In addition, because the products and services of many companies in the healthcare sector affect the health and well-being of many individuals, these companies are especially susceptible to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, which can result in increased development costs, delayed cost recovery and loss of competitive advantage to the extent that rival companies have developed competing products or procedures, adversely affecting the company’s revenues and profitability. In other words, delays in the regulatory approval process may diminish the opportunity for a company to profit from a new product or to bring a new product to market, which could have a material adverse effect on a company’s business. Healthcare companies may also be strongly affected by scientific biotechnology or technological developments, and their products may quickly become obsolete. Also, many healthcare companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. Changes in governmental policies or laws may span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of healthcare services, tax incentives and penalties related to healthcare insurance premiums, and promotion of prepaid healthcare plans. In addition, a number of

legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Additionally, the expansion of facilities by healthcare-related providers may be subject to “determinations of need” by certain government authorities. This process not only generally increases the time and costs involved in these expansions, but also makes expansion plans uncertain, limiting the revenue and profitability growth potential of healthcare-related facilities operators and negatively affecting the prices of their securities. Moreover, in recent years, both local and national governmental budgets have come under pressure to reduce spending and control healthcare costs, which could both adversely affect regulatory processes and public funding available for healthcare products, services and facilities.

Risk of Investing in the Industrials Sector. The value of securities issued by companies in the industrials sector may be adversely affected by supply of and demand for both their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, trade disputes, world events and economic conditions may affect the performance of companies in the industrials sector. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. For example, commodity price declines and unit volume reductions resulting from an over-supply of materials used in the industrials sector can adversely affect the sector. Furthermore, while the Underlying Funds seek to invest in companies with positive or favorable environmental, social, and governance (“ESG”) characteristics, companies in the industrials sector may be subject to liability for environmental damage, product liability claims, depletion of resources, and mandated expenditures for safety and pollution control.

Risk of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Finally, while all companies may be susceptible to network security breaches, certain companies in the information technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. These risks are heightened for information technology companies in foreign markets.

Risk of Investing in the Materials Sector. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, social and political unrest, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, and mandated expenditures for safety and pollution control, among other factors. Such risks may adversely affect the issuers to which the Funds and the Underlying Funds have exposure. While the Underlying Funds seek to invest in companies with positive or favorable environmental, social, and governance (“ESG”) characteristics, companies in the materials sector are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns. These risks are heightened for companies in the materials sector located in foreign markets.

Risk of Investing in the Real Estate Industry. Companies in the real estate industry include companies that invest in real estate, such as real estate investment trusts (“REITs”), real estate holding and operating companies or real estate development companies (collectively, “Real Estate Companies”). Investing in Real Estate Companies exposes investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are

organized and operated. The real estate industry is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Investing in Real Estate Companies involves various risks. Some risks that are specific to Real Estate Companies are discussed in greater detail below.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region or property type. Economic downturns affecting a particular region, industry or property type may lead to a high volume of defaults within a short period.

Distressed Investment Risk. Real Estate Companies may invest in distressed, defaulted or out-of-favor bank loans. Identification and implementation by a Real Estate Company of loan modification and restructure programs involves a high degree of uncertainty. Even successful implementation may still require adverse compromises and may not prevent bankruptcy. Real Estate Companies may also invest in other debt instruments that may become non-performing, including the securities of companies with higher credit and market risk due to financial or operational difficulties. Higher risk securities may be less liquid and more volatile than the securities of companies not in distress.

Illiquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of small-capitalization companies, may be more volatile than, and perform differently from, shares of large-capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid, and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations. Declining interest rates could result in increased prepayment on loans and require redeployment of capital in less desirable investments.

Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Real Estate Companies are also exposed to the risks normally associated with debt financing. Financial covenants related to a Real Estate Company’s leverage may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.

Loan Foreclosure Risk. Real Estate Companies may foreclose on loans that the Real Estate Company originated and/or acquired. Foreclosure may generate negative publicity for the underlying property that affects its market value. In addition to the length and expense of such proceedings, the validity of the terms of the applicable loan may not be recognized in foreclosure proceedings. Claims and defenses asserted by borrowers or other lenders may interfere with the enforcement of rights by a Real Estate Company. Parallel proceedings, such as bankruptcy, may also delay resolution and limit the amount of recovery on a foreclosed loan by a Real Estate Company even where the property underlying the loan is liquidated.

Management Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and voluntary liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint venture investments in certain of its properties, and, consequently, its ability to control decisions relating to such properties may be limited.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changes in consumer preferences and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes, mandated closures or other

commercial restrictions or environmental regulations, also may have a major impact on real estate income and values. In addition, quarterly compliance with regulations limiting the proportion of asset types held by a U.S. REIT may force certain Real Estate Companies to liquidate or restructure otherwise attractive investments. Some countries may not recognize REITs or comparable structures as a viable form of real estate funds.

Underlying Investment Risk. Real Estate Companies make investments in a variety of debt and equity instruments with varying risk profiles. For instance, Real Estate Companies may invest in debt instruments secured by commercial property that have higher risks of delinquency and foreclosure than loans on single family homes due to a variety of factors associated with commercial property, including the tie between income available to service debt and productive use of the property. Real Estate Companies may also invest in debt instruments and preferred equity that are junior in an issuer’s capital structure and that involve privately negotiated structures. Subordinated debt investments, such as B-Notes and mezzanine loans, involve a greater credit risk of default due to the need to service more senior debt of the issuer. Similarly, preferred equity investments involve a greater risk of loss than conventional debt financing due to their non-collateralized nature and subordinated ranking. Investments in CMBS may also be junior in priority in the event of bankruptcy or similar proceedings. Investments in senior loans may be effectively subordinated if the senior loan is pledged as collateral. The ability of a holder of junior claims to proceed against a defaulting issuer is circumscribed by the terms of the particular contractual arrangement, which vary considerably from transaction to transaction.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries. Because REITs often do not provide complete tax information until after the calendar year-end, an Underlying Fund may at times need to request permission to extend the deadline for issuing your tax reporting statement or supplement the information otherwise provided to you.

Risk of Investing in the Utilities Sector. The utilities sector may be adversely affected by changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects.

There are substantial differences among the regulatory practices and policies of various jurisdictions, and any regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in an Underlying Funds' portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climate conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.

The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Rate changes may occur only after a prolonged approval period or may not occur at all, which could adversely affect utility companies when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. As a result, some companies may be forced to defend their core business and may be less profitable. Deregulation may also permit a utility company to expand outside of its traditional lines of business and engage in riskier ventures.

Proxy Voting Policy

For the Funds, the Board has delegated the voting of proxies for each Fund’s securities to BFA pursuant to the Funds' Proxy Voting Policy, and BFA has adopted policies and procedures (collectively, the “iShares ETFs Proxy Voting Policies”) governing proxy voting by accounts managed by BFA, including the Funds.

Under the iShares ETFs Proxy Voting Policies, BFA will vote proxies related to Fund securities in the best interests of a Fund and its shareholders. From time to time, a vote may present a conflict between the interests of a Fund’s shareholders, on the one hand, and those of BFA, or any affiliated person of a Fund or BFA, on the other. BFA maintains policies and procedures that are designed to prevent undue influence on BFA’s proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BFA, BFA’s affiliates, a Fund or a Fund’s affiliates. Most conflicts are managed through a structural separation of BFA’s Corporate Governance Group from BFA’s employees with sales and client responsibilities. In addition, BFA maintains procedures to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BFA’s relationship with the issuer of the proxy or the dissident shareholder. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law.

Copies of the iShares ETFs Proxy Voting Policies are attached as Appendix A.

Information with respect to how proxies relating to the Funds' portfolio securities were voted during the 12-month period ended June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Funds' website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

On each Business Day (as defined in the Creation and Redemption of Creation Units section of this SAI), prior to the opening of regular trading on the Fund’s primary listing exchange, a Fund discloses on its website (www.iShares.com) certain information relating to the portfolio holdings that will form the basis of a Fund’s next net asset value per share calculation.

In addition, certain information may also be made available to certain parties:

•

Communications of Data Files: A Fund may make available through the facilities of the National Securities Clearing Corporation (“NSCC”) or through posting on the www.iShares.com, prior to the opening of trading on each business day, a list of a Fund’s holdings (generally pro-rata) that Authorized Participants could deliver to a Fund to settle purchases of a Fund (i.e. Deposit Securities) or that Authorized Participants would receive from a Fund to settle redemptions of a Fund (i.e. Fund Securities). These files are known as the Portfolio Composition File and the Fund Data File (collectively, “Files”). The Files are applicable for the next trading day and are provided to the NSCC and/or posted on www.iShares.com after the close of markets in the U.S.

•

Communications with Authorized Participants and Liquidity Providers: Certain employees of BFA are responsible for interacting with Authorized Participants and liquidity providers with respect to discussing custom basket proposals as described in the Custom Baskets section of this SAI. As part of these discussions, these employees may discuss with an Authorized Participant or liquidity provider the securities a Fund is willing to accept for a creation, and securities that a Fund will provide on a redemption.

BFA employees may also discuss portfolio holdings-related information with broker/dealers, in connection with settling a Fund’s transactions, as may be necessary to conduct business in the ordinary course in a manner consistent with the disclosure in the Fund's current registration statement.

•

Communications with Listing Exchanges: From time to time, employees of BFA may discuss portfolio holdings information with the applicable primary listing exchange for a Fund as needed to meet the exchange listing standards.

•

Communications with Other Portfolio Managers: Certain information may be provided to employees of BFA who manage funds that invest a significant percentage of their assets in shares of an underlying fund as necessary to manage the fund’s investment objective and strategy.

•

Communication of Other Information: Certain explanatory information regarding the Files is released to Authorized Participants and liquidity providers on a daily basis, but is only done so after the Files are posted to www.iShares.com.

•

Third-Party Service Providers: Certain portfolio holdings information may be disclosed to Fund Trustees and their counsel, outside counsel for the Funds, auditors and to certain third-party service providers (i.e., fund administrator, custodian, proxy voting service) for which a non-disclosure, confidentiality agreement or other obligation is in place with such service providers, as may be necessary to conduct business in the ordinary course in a manner consistent with applicable policies, agreements with the Funds, the terms of the current registration statements and federal securities laws and regulations thereunder.

•

Liquidity Metrics: “Liquidity Metrics,” which seek to ascertain a Fund’s liquidity profile under BlackRock’s global liquidity risk methodology, include but are not limited to: (a) disclosure regarding the number of days needed to liquidate a portfolio or the portfolio’s underlying investments; and (b) the percentage of a Fund’s NAV invested in a particular liquidity tier under BlackRock’s global liquidity risk methodology. The dissemination of position-level liquidity metrics data and any non-public regulatory data pursuant to the Liquidity Rule (including SEC liquidity tiering) is not permitted unless pre-approved. Disclosure of portfolio-level liquidity metrics prior to 60 calendar days after calendar quarter-end requires a non-disclosure or confidentiality agreement and approval of the Trust’s Chief Compliance Officer. Portfolio-level liquidity metrics disclosure subsequent to 60 calendar days after calendar quarter-end requires the approval of portfolio management and must be disclosed to all parties requesting the information if disclosed to any party.

The Trust’s Chief Compliance Officer or his delegate may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures, subject to restrictions on selective disclosure imposed by applicable law. The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

The BlackRock ESG Aware Allocation Index Series

Index Construction

Each Underlying Index is composed of a portfolio of equity and fixed income Underlying Funds that invest primarily in companies or issuers that exhibit positive environmental, social and governance (“ESG”) characteristics as identified by the index provider of each Underlying Fund in distinct asset classes, such as large-, mid-, or small-capitalization U.S. or non-U.S. equity, and the broad U.S. dollar-denominated investment-grade bond market. At the semi-annual rebalancing in April and October, the weights of the Underlying ETFs representing equity or fixed income asset classes are determined according to the following steps:

The weights allocated to equity and fixed income are pre-determined for each index as indicated in the table below.

Allocation to Equity and Fixed Income
Index	Equity	Fixed Income
BlackRock ESG Aware Aggressive Allocation Index	80%	20%
BlackRock ESG Aware Conservative Allocation Index	30%	70%
BlackRock ESG Aware Growth Allocation Index	60%	40%

Allocation to Equity and Fixed Income
BlackRock ESG Aware Moderate Allocation Index	40%	60%

The relative weights of Underlying Funds representing equity are determined using the free float-adjusted market capitalization of the parent index of each Underlying Fund’s respective index.

The weight to the fixed income asset class is represented entirely by the iShares ESG Aware U.S. Aggregate Bond ETF.

Eligible Securities. Each Underlying Index is comprised exclusively of iShares ETFs that invest primarily in companies or issuers that exhibit positive ESG characteristics as identified by the index provider of each Underlying Fund. To be eligible for inclusion in an index, an ETF must track a benchmark that exhibits positive ESG characteristics, is broadly representative of a major asset class and be registered as an investment company under the 1940 Act. As of July 31, 2023, the universe of eligible asset classes and the instruments used to represent each ETF are:

Asset Class	iShares ETF
U.S. Large- and Mid-Cap	iShares ESG Aware MSCI USA ETF
U.S. Small-Cap	iShares ESG Aware MSCI Small-Cap ETF
Developed Markets	iShares ESG Aware MSCI EAFE ETF
Emerging Markets	iShares ESG Aware MSCI EM ETF
Developed Markets	iShares ESG Aware U.S. Aggregate Bond ETF

Index Changes. Index constituents are not expected to change between rebalancing periods. The activities of the Index Provider are overseen by the Index Services Governance Committee(“ISGCo”). ISGCo provides oversight for activities pertaining to the calculation and dissemination of BlackRock proprietary Indices and ensure adherence to any policies, procedures and business practices relating to the activities of the Index Provider. If for example, an Underlying Fund is delisted by its principal exchange, this would constitute an index methodology change and the Index Provider's policy governing methodology changes would apply.

Rebalancing. Each index is rebalanced semi-annually after the market close on the last business day of April and October. Market capitalization data used to determine the weights of each Underlying Fund representing equity asset classes at the rebalance is from 5 business days prior to the last business day of April and October.

Investment Policies

The Board has adopted as fundamental policies the following numbered investment policies, which cannot be changed without the approval of the holders of a majority of the applicable Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities of each Fund is defined in the Investment Company Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of each Fund are present or represented by proxy, or (ii) more than 50% of the outstanding voting securities of each Fund. Each Fund has also adopted certain non-fundamental investment policies, including its investment objective. Non-fundamental investment policies may be changed by the Board without shareholder approval. Therefore, each Fund may change its investment objective and its Underlying Index without shareholder approval.

Fundamental Investment Policies

Each Fund may not:

Concentrate its investments in a particular industry, as that term is used in the Investment Company Act, except that the Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of a particular industry or group of industries.

Borrow money, except as permitted under the Investment Company Act.

Issue senior securities to the extent such issuance would violate the Investment Company Act.

Purchase or hold real estate, except the Fund may purchase and hold securities or other instruments that are secured by, or linked to, real estate or interests therein, securities of REITs, mortgage-related securities and securities of issuers engaged in the real estate business, and the Fund may purchase and hold real estate as a result of the ownership of securities or other instruments.

Underwrite securities issued by others, except to the extent that the sale of portfolio securities by the Fund may be deemed to be an underwriting or as otherwise permitted by applicable law.

Purchase or sell commodities or commodity contracts, except as permitted by the Investment Company Act.

Make loans to the extent prohibited by the Investment Company Act.

Notations Regarding each Fund's Fundamental Investment Policies

The following notations are not considered to be part of each Fund’s fundamental investment policies and are subject to change without shareholder approval.

With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to each Fund's industry classifications, each Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to each Fund as to how to classify issuers within or among industries.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits each Fund to borrow money in amounts of up to one-third of the Fund's total assets from banks for any purpose, and to borrow up to 5% of the Fund's total assets from banks or other lenders for temporary purposes. (The Fund's total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires each Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage

means the ratio that the value of each Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with Rule 18f-4 under the Investment Company Act, when each Fund engages in reverse repurchase agreements and similar financing transactions, the Fund may either (i) maintain asset coverage of at least 300% with respect to such transactions and any other borrowings in the aggregate, or (ii) treat such transactions as “derivatives transactions” and comply with Rule 18f-4 with respect to such transactions. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit a fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits a fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of a fund’s underwriting commitments, when added to the value of a fund’s investments in issuers where a fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause a fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent a fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether a fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit each Fund from making loans (including lending its securities); however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Non-Fundamental Investment Policies

If any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction, except that certain percentage limitations will be observed continuously in accordance with applicable law.

Each Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in the component securities (including indirect investments through the underlying fund) and other instruments of its Underlying Index or in depositary receipts representing component securities in its Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, a Fund's future investments will be made in a manner that will bring the Fund into compliance with this policy.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Funds on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand

for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all of the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board has responsibility for the overall management and operations of the Funds, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. Each officer shall hold office until his or her successor is elected and qualifies or until his or her death, resignation or removal. Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust are referred to as independent trustees (“Independent Trustees”).

The registered investment companies advised by BFA or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of open-end equity, multi-asset, index and money market funds and ETFs (the “BlackRock Multi-Asset Complex”), one complex of closed-end funds and open-end non-index fixed-income funds (including ETFs) (the “BlackRock Fixed-Income Complex”) and one complex of ETFs (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). Each Fund is included in the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Trustee of iShares U.S. ETF Trust and, as a result, oversees all of the funds within the Exchange-Traded Fund Complex, which consists of 404 funds as of December 1, 2023. With the exception of Robert S. Kapito, Dominik Rohé and Aaron Wasserman, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Rohé and Mr. Wasserman is c/o BlackRock, Inc., 50 Hudson Yards, New York, NY 10001. The Board has designated John E. Kerrigan as its Independent Board Chair.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds' investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Funds rests with the Board. The Board has engaged BFA to manage the Funds on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Funds in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of nine members, seven of whom are Independent Trustees. The Board currently conducts regular in person meetings four times a year. In addition, the Board frequently holds special in person or telephonic meetings

or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Board Chair. The Board Chair’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Board Chair may also perform such other functions as may be delegated by the Board from time to time. The Board has established seven standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending Committee, a Risk Committee, an Equity Plus Committee and a Fixed Income Plus Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time the Board may establish ad hoc committees or informal working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Chair of each standing Committee is an Independent Trustee. The role of the Chair of each Committee is to preside at all meetings of the Committee and to act as a liaison with service providers, officers, attorneys and other Trustees between meetings. Each standing Committee meets regularly to conduct the oversight functions delegated to the Committee by the Board and reports its finding to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Funds is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. Each Fund is subject to a number of risks, including investment, compliance, operational, reputational, counterparty and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to identify and eliminate all of the risks applicable to the Funds. The Trustees have an oversight role in this area, satisfying themselves that risk management processes and controls are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of each Fund and is addressed as part of various Board and committee activities. In some cases, risk management issues are specifically addressed in presentations and discussions. For example, BFA has an independent dedicated Risk and Quantitative Analysis Group (“RQA”) that assists BFA in managing fiduciary and corporate risks, including investment, operational, counterparty credit and enterprise risk. Representatives of RQA meet with the Board to discuss their analysis and methodologies, as well as specific risk topics such as operational and counterparty risks relating to the Funds. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by each Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust's compliance program, including assessments by independent third parties, and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer (and his or her delegates) assesses key compliance risks affecting each Fund, and addresses them in periodic reports to the Board. In addition, the Audit Committee meets with both the Funds' independent registered public accounting firm and BFA’s internal audit group to review risk controls in place that support each Fund as well as test results. Board oversight of risk is also performed as needed between meetings through communications between BFA and the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities. From time to time, the Board may modify the manner in which it conducts risk oversight. The Board’s oversight role does not make it a guarantor of the Funds' investment performance or other activities.

Committees of the Board of Trustees. The members of the Audit Committee are Richard L. Fagnani (Chair), Cecilia H. Herbert and Madhav V. Rajan, each of whom is an Independent Trustee. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust's accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust's financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust's accounting and financial reporting, internal controls, compliance controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met four times during the fiscal year ended July 31, 2023.

The members of the Nominating and Governance Committee are Cecilia H. Herbert (Chair), Madhav V. Rajan and Drew E. Lawton, each of whom is an Independent Trustee. The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board and recommends appointments to the Advisory Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Board Chair; (v) periodic review of the Board's retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Board Chair and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nominations recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity). The Nominating and Governance Committee met three times during the fiscal year ended July 31, 2023.

Each Independent Trustee serves on the 15(c) Committee. The Chair of the 15(c) Committee is Drew E. Lawton. The principal responsibilities of the 15(c) Committee are to support, oversee and organize on behalf of the Board the process for the annual review and renewal of the Trust's advisory and sub-advisory agreements.

The members of the Securities Lending Committee are John E. Martinez (Chair), Jane D. Carlin and Drew E. Lawton, each of whom is an Independent Trustee.

These responsibilities include: (i) requesting that certain information be provided to the Committee for its review and consideration prior to such information being provided to the Board; (ii) considering and discussing with BlackRock, Inc. such other matters and information as may be necessary and appropriate for the Board to oversee the Trust's securities lending activities and make required findings and approvals; and (iii) providing a recommendation to the Board regarding the annual approval of the Trust's Securities Lending Guidelines and the required findings with respect to, and annual approval of, the Trust's agreement with the securities lending agent. The Securities Lending Committee met five times during the fiscal year ended July 31, 2023.

As of December 31, 2022, none of the Independent Trustees or their immediate family members owned beneficially or of record any securities of BFA (the Funds' investment adviser), the Distributor or any person controlling, controlled by or under common control with BFA or the Distributor.

Conflicts of Interest. Certain activities of BFA, BlackRock, Inc. and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as “BlackRock”) and their respective directors, officers and employees, with respect to the Funds and/or other accounts managed by BlackRock, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world's largest asset management firms. BlackRock, its subsidiaries and their respective directors, officers and employees, including the business units or entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and have interests other than that of managing the Funds. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage a Fund and its shareholders. These businesses and interests include potential multiple advisory, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by a Fund.

BlackRock has proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Funds. BlackRock is also a major participant in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, BlackRock is or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Funds.

When BlackRock seeks to purchase or sell the same assets for managed accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for a Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of a Fund, particularly, but not limited to, with respect to small-capitalization, emerging market or less liquid strategies. This may occur with respect to BlackRock-advised accounts when investment decisions regarding a Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for a Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) BlackRock or its other accounts or funds, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) BlackRock or its other accounts or funds. In addition, to the extent permitted by applicable law, certain Funds may invest their assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and sales, and increased remuneration and profitability for BlackRock, and/or its personnel, including portfolio managers.

In certain circumstances, BlackRock, on behalf of the Funds, may seek to buy from or sell securities to another fund or account advised by BlackRock. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients (“cross trades”), including the Funds, if BlackRock believes such transactions are appropriate based on each party's investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock’s decision to engage in these transactions for the Funds. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions. On any occasion when a Fund participates in a cross trade, BlackRock will comply with procedures adopted under applicable rules and SEC guidance.

BlackRock and its clients may pursue or enforce rights with respect to an issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of a Fund's investments may be negatively impacted by the activities of BlackRock or its clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of a Fund’s investment activities may differ significantly from the results achieved by BlackRock for its proprietary accounts or other accounts (including investment companies or collective investment vehicles) which it manages or advises. It is possible that one or more accounts managed or advised by BlackRock and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by a Fund. Moreover, it is possible that a Fund will sustain losses during periods in which one or more proprietary or other accounts managed or advised by BlackRock achieve significant profits. The opposite result is also possible.

From time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or other accounts managed or advised by BlackRock, and/or the internal policies of BlackRock designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock is performing services or when position limits have been reached. For example, the investment activities of BlackRock for its proprietary accounts and accounts under its management may limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by BlackRock. BlackRock will not be under any obligation, however, to effect transactions on behalf of a Fund in accordance with such analysis and models. In addition, BlackRock will not have any obligation to make available any information regarding its proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of a Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock, or the activities or strategies used for accounts managed by BlackRock or other client accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

The Funds may be included in investment models developed by BlackRock for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Funds, the investment management fee amounts paid by the Funds to BlackRock may also increase. The price, availability and liquidity of a Fund may be impacted by purchases and sales of the Fund by model-driven investment portfolios, as well as by BlackRock itself and by its advisory clients.

In addition, certain principals and certain employees of a Fund’s investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their clients may be a consideration of which investors in a Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of a Fund in which clients of BlackRock or, to the extent permitted by the SEC and applicable law, BlackRock serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by a Fund may enhance the profitability of BlackRock.

BlackRock may also create, write or issue derivatives for clients based on the underlying securities, currencies or instruments in which a Fund may invest or on the performance of the Fund. An entity in which BlackRock has a significant minority interest will create, write or issue options which may be based on the performance of certain Funds. BlackRock has the right to receive a portion of the gross revenue earned by such entity. Options writing by such entity on a Fund could potentially lead to increased purchase activity with respect to the Fund and increased assets under management for BlackRock.

BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for underlying fixed-income indexes used by certain iShares funds, related to derivative fixed-income products that are based on such iShares funds. BlackRock may receive certain payments for licensing intellectual property belonging to BlackRock and for facilitating the provision of data in connection with such derivative products, which may include payments based on the trading volumes of, or revenues generated by, the derivative products. However, BlackRock will not receive any such payments on those derivative products utilized by the Funds or other BlackRock funds or accounts. Other funds and accounts managed by BlackRock may from time to time transact in such derivative products, which could contribute to the viability or success of such derivative products by making them more appealing to funds and accounts managed by third parties, and in turn lead to increased payments to BlackRock. Trading activity in such derivative products could also potentially lead to increased purchase activity with respect to these iShares funds and increased assets under management for BlackRock.

A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock and may also enter into transactions with other clients of BlackRock where such other clients have interests adverse to those of the Fund.

At times, these activities may cause business units or entities within BlackRock to give advice to clients that may cause these clients to take actions adverse to the interests of a Fund. To the extent such transactions are permitted, a Fund will deal with BlackRock on an arm’s-length basis.

To the extent authorized by applicable law, BlackRock may act as broker, dealer, agent, lender or adviser or in other commercial capacities for a Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by BlackRock will be in its view commercially reasonable, although BlackRock, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock and such sales personnel, which may have an adverse effect on the Funds. Index based funds may use an index provider that is affiliated with another service provider of a Fund or BlackRock that acts as a broker, dealer, agent, lender or in other commercial capacities for a Fund or BlackRock.

Subject to applicable law, BlackRock (and its personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Funds or their shareholders will be required, and no fees or other compensation payable by the Funds or their shareholders will be reduced by reason of receipt by BlackRock of any such fees or other amounts.

When BlackRock acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, BlackRock may take commercial steps in its own interests, which may have an adverse effect on the Funds. A Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. BlackRock will not have any obligation to allow its credit to be used in connection with a Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock in evaluating the Fund's creditworthiness.

BTC, an affiliate of BFA pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Funds. BlackRock will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interests in managing a securities lending program, including but not limited to: (i) BlackRock as securities lending agent may have an incentive to, among other things, increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BlackRock and its affiliates; and (ii) BlackRock as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro rata allocation.

As part of its securities lending program, BlackRock indemnifies the Funds and certain other clients and/or funds against a shortfall in collateral in the event of borrower default. On a regular basis, BlackRock calculates the potential dollar exposure of collateral shortfall resulting from a borrower default (“shortfall risk”) in the securities lending program. BlackRock establishes program-wide borrower limits (“credit limits”) to actively manage borrower-specific credit exposure. BlackRock oversees the risk model that calculates projected collateral shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower credit characteristics. When necessary, BlackRock may adjust securities lending program attributes by restricting eligible collateral or reducing borrower credit limits. As a result, the management of program-wide exposure as well as BlackRock-specific indemnification exposure may affect the amount of securities lending activity BlackRock may conduct at any given point in time by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock uses a predetermined systematic process in order to approximate pro rata allocation over time. In order to allocate a loan to a portfolio: (i) BlackRock as a whole must have sufficient lending capacity pursuant to the various program limits (i.e., indemnification exposure limit and borrower credit limits); (ii) the lending portfolio must hold the asset at the time a loan opportunity arrives; and (iii) the lending portfolio must also have enough inventory, either on its own or when aggregated with other portfolios into one single market delivery, to satisfy the loan request. In doing so, BlackRock seeks to provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

BlackRock may decline to make a securities loan on behalf of a Fund, discontinue lending on behalf of a Fund or terminate a securities loan on behalf of a Fund for any reason, including but not limited to regulatory requirements and/or market rules, liquidity considerations, or credit considerations, which may impact Funds by reducing or eliminating the volume of lending opportunities for certain types of loans, loans in particular markets, loans of particular securities or types of securities, or for loans overall.

Purchases and sales of securities and other assets for a Fund may be bunched or aggregated with orders for other BlackRock client accounts, including with accounts that pay different transaction costs solely due to the fact that they have different research payment arrangements. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

Subject to applicable law, BlackRock may select brokers that furnish BlackRock, the Funds, other BlackRock client accounts or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing any or all of the Funds and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock does not currently enter into arrangements to use the Funds' assets for, or participate in, soft dollars, although BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock. BlackRock, unless prohibited by applicable law, may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock, unless prohibited by applicable law, may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock has an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock owns a minority interest in, and is a member of, Members Exchange (“MEMX”), a newly created U.S. stock exchange. Transactions for a Fund may be executed on MEMX if third party brokers select MEMX as the appropriate venue for execution of orders placed by BlackRock traders on behalf of such Funds. In addition, transactions in Fund shares may be executed on MEMX if third party brokers select MEMX as the appropriate venue for the execution of such orders.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock and/or its advisory clients (including other funds and separately managed accounts) may, subject to compliance with applicable law, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance liquidity, investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund's expense ratio. BlackRock reserves the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of a Fund acquired for its own accounts or the account of a BlackRock advisory client. A large sale or redemption of shares of a Fund by BlackRock itself or a BlackRock advisory client could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund.

It is possible that a Fund may invest in securities of, or engage in transactions with, companies in which BlackRock has significant debt or equity investments or other interests. A Fund may also invest in issuances (such as structured notes) by entities for which BlackRock provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any unit of BlackRock in the course of these activities. In addition, from time to time, the activities of BlackRock may limit a Fund's flexibility in purchases and sales of securities. As indicated below, BlackRock may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock have an investment.

BlackRock, its personnel and other financial service providers may have interests in promoting sales of the Funds. With respect to BlackRock and its personnel, the remuneration and profitability relating to services to and sales of the Funds or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Funds or their shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock and such personnel resulting from transactions on behalf of or management of the Funds may be greater than the remuneration and profitability resulting from other funds or products.

Third parties, including service providers to BlackRock or a Fund, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to a Fund.

BlackRock may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for such clients' accounts may differ from the valuations for the same securities or investments assigned by a Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section in this SAI, when market quotations are not readily available or are believed by BFA to be unreliable, each Fund’s investments are valued at fair value by BFA. BFA has been designated as each Fund’s valuation designee pursuant to Rule 2a-5 under the Investment Company Act and acts through BFA’s Rule 2a-5 Committee (the “2a-5 Committee”), with assistance from other BFA pricing committees and in accordance with BFA’s policies and procedures (the “Valuation Procedures”). When determining a “fair value price,” the 2a-5 Committee seeks to determine the price that a Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction. The price generally may not be determined based on what a Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BFA deems relevant at the time of the determination, and may be based on analytical values determined by BFA using proprietary or third-party valuation models, fair value represents only a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s NAV. As a result, a Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued by the 2a-5 Committee at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BFA with respect to services for which it receives an asset-based fee.

To the extent permitted by applicable law, a Fund may invest all or some of its short-term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, a Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in a Fund bearing some additional expenses.

BlackRock and its directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers and employees that are the same, different from or made at different times than positions taken for a Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, each Fund, BFA and BlackRock have each adopted a code of ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding a Fund's portfolio transactions. Each code of ethics is available by contacting BlackRock at the telephone number on the back cover of each Fund’s Prospectus or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at [email protected].

BlackRock will not purchase securities or other property from, or sell securities or other property to, a Fund, except that a Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with another Fund or accounts that are affiliated with a Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for a Fund to purchase and another client of BlackRock to sell, or a Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit its advice in certain securities or instruments issued by or related to companies for which BlackRock is performing advisory or other services or has proprietary positions. For example, when BlackRock is engaged to provide advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of a Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock serve as directors of companies the securities of which a Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Funds may purchase securities or instruments that are issued by such companies, are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

The investment activities of BlackRock for its proprietary accounts and for client accounts may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, or are subject to corporate or regulatory ownership restrictions, or invest in certain futures or other derivative transactions, there may be limits on the aggregate amount invested by BlackRock for their proprietary accounts and for client accounts (including the Funds) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or a Fund or as a result of third-party transactions, the ability of BlackRock, on behalf of clients (including the Funds), to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of its clients (including the Funds), may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Funds), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage such Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock’s intended strategy with respect to such security or asset.

BlackRock may not serve as an Authorized Participant in the creation and redemption of iShares ETFs.

Under an ETF Services Agreement, certain Funds have retained BRIL, an Affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation

Units of the Funds (“ETF Services”). BRIL will retain a portion of the standard transaction fee received from Authorized Participants on each creation or redemption order from the Authorized Participant for the ETF Services provided. BlackRock collaborated with, and received payment from, Citibank, N.A. (“Citibank”) on the design and development of the ETF Services platform. Citibank may have, or from time to time may develop, additional relationships with BlackRock or funds managed by BFA and its affiliates.

BlackRock may maintain securities indices. To the extent permitted by applicable laws, the Funds may seek to license and use such indices as part of their investment strategy. Index based funds that seek to track the performance of securities indices also may use the name of the index or index provider in the fund name. Index providers, including BlackRock (to the extent permitted by applicable law), may be paid licensing fees for use of their index or index name. In instances where BlackRock charges a unitary management fee, BlackRock may have a financial incentive to use a BlackRock index that is less costly to BlackRock than a third party index. BlackRock may benefit from the Funds using BlackRock indices by creating increasing acceptance in the marketplace for such indices. BlackRock is not obligated to license its indices to a Fund and the Funds are under no obligation to use BlackRock indices. Any Fund that enters into a license for a BlackRock index cannot be assured that the terms of any index licensing agreement with BlackRock will be as favorable as those terms offered to other licensees.

BlackRock may enter into contractual arrangements with third-party service providers to a Fund (e.g., custodians, administrators and index providers) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. BlackRock may also enter into contractual arrangements with such service providers pursuant to which BlackRock incurs additional costs if the service provider’s services are terminated with respect to a Fund. To the extent that BlackRock is responsible for paying service providers out of its fees that it receives from the Funds, the benefits of lower fees, including any fee discounts or concessions, or any additional savings, may accrue, in whole or in part, to BlackRock, which could result in conflicts of interest relating to the use or termination of service providers to a Fund. In addition, conflicts of interest may arise with respect to contractual arrangements with third-party service providers to a Fund, or the selection of such providers, particularly in circumstances where BlackRock is negotiating on behalf of both funds that have a unitary management fee and those that do not or different service providers have different fee structures.

Conflicts of interest may arise as a result of simultaneous investment management of multiple client accounts by the BlackRock’s investment professionals. For example, differences in the advisory fee structure may create the appearance of actual or potential conflicts of interest because such differences could create pecuniary incentives for BlackRock to favor one client account over another.

BlackRock owns or has an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Funds, that engage the service provider (typically the custodian). A Fund’s service provider remunerates BlackRock for the use of the systems. A Fund service provider’s payments to BlackRock for the use of these systems may enhance the profitability of BlackRock.

BlackRock’s receipt of fees from a service provider in connection with the use of systems provided by BlackRock may create an incentive for BlackRock to recommend that a Fund enter into or renew an arrangement with the service provider.

In recognition of a BlackRock client’s overall relationship with BlackRock, BlackRock may offer special pricing arrangements for certain services provided by BlackRock. Any such special pricing arrangements will not apply to the client’s investment in a Fund.

Present and future activities of BlackRock (including BFA), its directors, officers and employees, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to each Fund pursuant to an investment advisory agreement between the Trust, on behalf of each Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the investment advisory agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of each Fund, manages and administers the Trust and the investment of each Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of each Fund.

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Funds will bear, the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, and litigation expenses and any extraordinary expenses (as determined by a majority of the Independent Trustees).

For its investment advisory services to each Fund, BFA received a management fee at the annual rates (as a percentage of such Fund's average net assets) set forth below for the fiscal years noted. BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc., provided that the waiver be no greater than the Fund's management fee, through November 30, 2025. The contractual waiver may be terminated prior to November 30, 2025 only upon written agreement of the Trust and BFA.

BFA may from time to time voluntarily waive and/or reimburse fees or expenses to reduce the Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

The following table sets forth the management fee (net of any applicable waivers) at the annual rate (as a percentage of each Fund’s average daily net assets) BFA received from each Fund for the fiscal year ended July 31, 2023 and the management fees (net of any applicable waivers) each Fund paid BFA for the fiscal years noted:

Fund	Management Fees Paid Net of Waivers for Fiscal Year Ended July 31, 2023	Management Fees Paid Net of Waivers for Fiscal Year Ended July 31, 2022	Management Fees Paid Net of Waivers for Fiscal Year Ended July 31, 2021
iShares ESG Aware Aggressive Allocation ETF	4,475	4,393	$1,919
iShares ESG Aware Conservative Allocation ETF	4,407	18,267	2,605
iShares ESG Aware Growth Allocation ETF	5,630	3,478	1,785
iShares ESG Aware Moderate Allocation ETF	2,690	3,106	2,317

For the fiscal years shown below, BFA waived the following management fees with respect to the Funds:

Fund	Fees Waived for Fiscal Year Ended July 31, 2023	Fees Waived for Fiscal Year Ended July 31, 2022	Fees Waived for Fiscal Year Ended July 31, 2021
iShares ESG Aware Aggressive Allocation ETF	$33,436	$32,936	$16.772
iShares ESG Aware Conservative Allocation ETF	9,259	38,318	5,847
iShares ESG Aware Growth Allocation ETF	22,614	13,761	7,942
iShares ESG Aware Moderate Allocation ETF	6,877	7,820	6,420

The investment advisory agreement with respect to each Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the applicable Fund, provided that in either event such continuance also is approved by a majority of the Board members who are not interested persons (as defined in the 1940 Act) of the applicable Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The investment advisory agreement with respect to each Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the applicable Fund’s outstanding voting securities (as defined in the 1940 Act). The investment advisory agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Underlying Funds. BFA serves as investment adviser to each of the Underlying Funds. Each Fund, as a shareholder of the Underlying Funds, bears a pro rata share of the Underlying Funds’ advisory fees, which are based on aggregate net assets, as listed in the chart below. Please note that the list of Underlying Funds below is as of July 31, 2023, but BFA may add, eliminate or replace Underlying Funds at any time.

Underlying Fund	Advisory Fee
iShares ESG Aware MSCI EAFE ETF	0.20 %
iShares ESG Aware MSCI EM ETF	0.25 %
iShares ESG Aware MSCI USA ETF	0.15 %
iShares ESG Aware MSCI USA Small-Cap ETF	0.17 %
iShares ESG Aware U.S. Aggregate Bond ETF	0.10 %

Portfolio Managers. As of July 31, 2023, the individuals named as Portfolio Managers in the Funds' Prospectuses were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as follows:

Jennifer Hsui

Types of Accounts	Number	Total Assets
Other Accounts	165	666,598,000,000

Pursuant to BFA’s policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds, seeking such investment opportunity. As a consequence, from time to time each Fund may receive a smaller allocation of an investment opportunity than they would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio’s or account’s gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or any of its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and each of its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intend to do so, shareholders of the Funds should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including performance-based fee arrangements, there is the potential for a conflict of interest, which may result in the Portfolio Managers favoring those portfolios or accounts with performance-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2023:

Portfolio Manager Compensation Overview

The discussion below describes the Portfolio Managers' compensation as of July 31, 2023.

BlackRock, Inc.'s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock, Inc.

Each portfolio manager receives base compensation based on their position with the firm, as well as retirement and other benefits offered to all BlackRock employees. Additionally, each portfolio manager receives discretionary incentive compensation, determined based on several components, including: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the performance of portfolios managed by the portfolio manager and the team relative to the portfolios’ investment objectives (which in the case of index ETFs would be how closely the ETF tracks its Underlying Index), and the individual’s performance and contribution to the overall performance of these portfolios and BlackRock. Discretionary incentive compensation is paid in cash up to a certain threshold with the remaining portion represented by deferred BlackRock, Inc. stock awards. In some cases, additional deferred BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance.

As of July 31, 2023, the Portfolio Managers did not beneficially own shares of the Funds.

Codes of Ethics. The Trust, BFA and the Distributor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act. The codes of ethics permit personnel subject to the codes of ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Funds. Each code of ethics is available by contacting BlackRock at the telephone number on the back cover of each Fund’s Prospectus or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at [email protected].

Anti-Money Laundering Requirements. The Funds are subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, a Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Funds reserve the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. Each Fund also reserves the right to redeem any amounts in a Fund from persons whose identity it is unable to verify on a timely basis. It is the Funds' policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. JPMorgan Chase Bank, N.A. (“JPMorgan”) serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement (the “Master Services Agreement”). JPMorgan’s principal address is 383 Madison Avenue, 11th Floor, New York, NY 10179. Pursuant to the Master Services Agreement with the Trust, JPMorgan provides necessary administrative, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In addition, JPMorgan makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Master Services Agreement with the Trust, JPMorgan maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. JPMorgan is required, upon the order of the Trust, to deliver securities held by JPMorgan and to make payments for securities purchased by the Trust for each Fund. JPMorgan is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Master Services Agreement with the Trust, JPMorgan acts as a transfer agent for each Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, JPMorgan receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of the Fund paid by BFA to JPMorgan for the period:

Distributor. The Distributor's principal address is 50 Hudson Yards, New York, NY 10001. Shares are continuously offered for sale by the Funds through the Distributor or its agent only in Creation Units, as described in the applicable Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are generally not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the applicable Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

The Distribution Agreement for each Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days' prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the relevant Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as described below), DTC participants and/or investor services organizations.

BFA or its affiliates may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

Securities Lending. To the extent that a Fund engages in securities lending, each Fund conducts its securities lending pursuant to SEC exemptive relief, and BTC acts as securities lending agent for the Funds, subject to the overall supervision of BFA, pursuant to a written agreement (the “Securities Lending Agency Agreement”).

Each Fund and Underlying Fund retains a portion of the securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income

earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund and Underlying Fund are responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees a Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

Under the securities lending program, the Funds are categorized into one of several specific asset classes. The determination of a Fund’s asset class category (fixed-income, domestic equity, international equity or fund-of-funds), each of which may be subject to a different fee arrangement, is based on a methodology agreed to by the Trust and BTC.

Pursuant to the current Securities Lending Agency Agreement:

(i) fund-of-funds, such as the Funds, retain 82% of securities lending income (which excludes collateral investment fees), and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined in the Management—Trustees and Officers section of this SAI) in a calendar year exceeds a specified threshold, each applicable fund-of-funds, pursuant to the current Securities Lending Agency Agreement, will receive for the remainder of that calendar year securities lending income as follows:

(i) 85% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

The services provided to the Funds by BTC in the most recent fiscal year ended July 31, 2023 primarily included the following:

(1) selecting borrowers from an approved list of borrowers and executing a securities lending agreement as agent on behalf of the Funds with each such borrower;

(2) negotiating the terms of securities loans, including the amount of fees;

(3) directing the delivery of loaned securities;

(4) monitoring the daily value of the loaned securities and directing the payment of additional collateral or the return of excess collateral, as necessary;

(5) investing cash collateral received in connection with any loaned securities;

(6) monitoring distributions on loaned securities (for example, interest and dividend activity);

(7) in the event of default by a borrower with respect to any securities loan, using the collateral or the proceeds of the liquidation of collateral to purchase replacement securities of the same issue, type, class and series as that of the loaned securities; and

(8) terminating securities loans and arranging for the return of loaned securities to the Funds at loan termination.

The following tables show the dollar amounts of income and fees/compensation related to the securities lending activities of each Fund during its most recent fiscal year ended July 31, 2023.

Payments by BFA and its Affiliates. BFA and/or its affiliates (“BFA Entities”) may pay certain broker-dealers, registered investment advisers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Funds, other iShares funds or exchange-traded products in general. BFA Entities make these payments from their own assets and not from the assets of the Funds. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Funds, other iShares funds (including, if applicable, any underlying iShares funds held by a Fund) or exchange-traded products, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Funds, other iShares funds or exchange-traded products. BFA Entities make payments for Intermediaries’ participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Funds and other iShares funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Funds, other iShares funds or exchange-traded products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Funds, other iShares funds or exchange-traded products available to their clients, in some cases at a waived or reduced commission rate or ticket charge, develop new products that feature iShares, create educational content about the Fund, other iShares

funds or exchange-traded products that is featured on an Intermediary’s platform, or otherwise promote the Funds, other iShares funds and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the iShares business or facilitate investment in the Funds, other iShares funds or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients, what services to provide for various products, or what marketing content to make available to its clients based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients. These financial incentives may cause the Intermediary to recommend the Funds, other iShares funds or exchange-traded products, or otherwise promote the Fund, other iShares funds or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

In addition to the payments described above, BFA Entities have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.BlackRock.com website at no additional cost to Intermediaries. BlackRock may configure these tools and calculators and localize the content for Intermediaries as part of its customary digital marketing support and promotion of the Funds, other iShares funds, exchange-traded products and BlackRock mutual funds.

As of March 1, 2013, BFA Entities have contractual arrangements to make payments (in addition to payments for Education Costs or Publishing Costs) to one Intermediary, Fidelity Brokerage Services LLC (“FBS”). Effective June 4, 2016, this relationship was expanded to include National Financial Services, LLC (“NFS”), an affiliate of FBS. Pursuant to this special, long-term and significant arrangement (the “Marketing Program”), FBS, NFS and certain of their affiliates (collectively “Fidelity”) have agreed, among other things, to actively promote iShares funds to customers, investment professionals and other intermediaries and in advertising campaigns as the preferred exchange-traded product, to offer certain iShares funds in certain Fidelity platforms and investment programs, in some cases at a waived or reduced commission rate or ticket charge, and to provide marketing data to BFA Entities. BFA Entities have agreed to facilitate the Marketing Program by, among other things, making certain payments to FBS and NFS for marketing and implementing certain brokerage and investment programs. Upon termination of the arrangement, the BFA Entities will make additional payments to FBS and/or NFS based upon a number of criteria, including the overall success of the Marketing Program and the level of services provided by FBS and NFS during the wind-down period.

In addition, BFA Entities may enter into other contractual arrangements with Intermediaries and certain other third parties that the BFA Entities believe may benefit the iShares business or facilitate investment in iShares funds. Such agreements may include payments by BFA Entities to such Intermediaries and third parties for data collection and provision, technology support, platform enhancement, or educational content, co-marketing and cross-promotional efforts. Payments made pursuant to such arrangements may vary in any year and may be different for different Intermediaries and third parties. In certain cases, the payments to Intermediaries are subject to certain minimum payment levels or tiered payments. As of the date of this SAI, the Intermediaries and other third parties receiving one or more types of the contractual payments described above include (in addition to FBS and NFS): Advisor Credit Exchange, Avantax Investment Services, Inc., BNY Mellon Capital Markets, LLC, BNY Mellon Performance & Risk Analytics, LLC, Charles Schwab & Co., Inc., Clearstream Fund Centre AG, Commonwealth Equity Services, LLC, Dorsey Wright and Associates, LLC, E*Trade Securities LLC, Envestnet Asset Management, Inc., eToro USA Securities Inc., LPL Financial LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley Smith Barney LLC, Northwestern Mutual Investment Services, LLC, Orion Portfolio Solutions, LLC, Pershing LLC, Public Holdings, Inc., Raymond James Financial Services, Inc., Riskalyze, Inc., Sanctuary Wealth Group, LLC, Stash Investments LLC, TD Ameritrade, Inc., UBS Financial Services Inc., Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC. Any additions, modifications, or deletions to Intermediaries and other third parties listed above that have occurred since the date of this SAI are not included in the list.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed in the immediately preceding paragraph. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a

year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Funds, other iShares funds or other exchange-traded products.

The Funds may participate in certain market maker incentive programs of a national securities exchange in which an affiliate of the Funds would pay a fee to the exchange used for the purpose of incentivizing one or more market makers in the securities of a Fund to enhance the liquidity and quality of the secondary market of securities of a Fund. The fee would then be credited by the exchange to one or more market makers that meet or exceed liquidity and market quality standards with respect to the securities of a Fund. Each market maker incentive program is subject to approval from the SEC. Any such fee payments made to an exchange will be made by an affiliate of a Fund solely for the benefit of a Fund and will not be paid from any Fund assets. Other funds managed by BFA may also participate in such programs.

Determination of Net Asset Value

Valuation of Shares. The NAV for each Fund is generally calculated as of the close of regular trading hours on the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern Time) on each business day the NYSE is open. Valuation of assets held by a Fund is as follows:

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each an “Exchange”) are valued using information obtained via independent pricing services, generally at the closing price or, if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which the assets or liabilities are valued. However, under certain circumstances, other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by a Fund on a day on which a Fund values such security, the prior day’s price will be used, unless BFA determines that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a Fair Value Asset (as defined below).

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options (except those that are customized) for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by a Fund on a day on which a Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no bid or ask price is available on a day on which a Fund values such option, the prior day’s price will be used, unless BFA determines that such prior day’s price no longer reflects the fair value of the option, in which case such option will be treated as a Fair Value Asset (as defined below). Customized exchange-traded equity options, as well as OTC derivatives, may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price or settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

Underlying Funds. Shares of underlying open-end funds (including money market funds) are valued at NAV. Shares of underlying exchange-traded closed-end funds or other ETFs will be valued at their most recent closing price.

General Valuation Information. Prices obtained from independent third-party pricing services, broker-dealers or market makers to value a Fund’s securities and other assets and liabilities are based on information available at the time a Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which a Fund valued such security, the revised pricing service quotation generally will be applied prospectively. Such determination will be made considering pertinent facts and circumstances surrounding the revision.

The price a Fund could receive upon the sale of any particular portfolio investment may differ from a Fund’s valuation of the investment, particularly for assets that trade in thin or volatile markets or that are valued using a fair valuation methodology

or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by a Fund, and a Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. A Fund’s ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

All cash, receivables and current payables are carried on a Fund’s books at their fair value.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by BFA, each Fund’s valuation designee, as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by a Fund (including restricted securities) are valued at fair value as determined in good faith by BFA pursuant to the Valuation Procedures. Any assets and liabilities which are denominated in a foreign currency are translated into U.S. dollars at the prevailing market rates.

Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate a Fund’s NAV and the prices used in the Underlying Index, which, in turn, could result in a difference between a Fund’s performance and the performance of the Underlying Index.

Fair Value. When market quotations are not readily available or are believed by BFA to be unreliable, a Fund’s investments are valued at fair value (“Fair Value Assets”). Fair Value Assets are valued by BFA in accordance with the Valuation Procedures. Pursuant to Rule 2a-5 under the Investment Company Act, the Board of Trustees has designated BFA as the valuation designee for the respective Funds for which it serves as investment adviser. BFA may reasonably conclude that a market quotation is not readily available or is unreliable if, among other things, a security or other asset or liability does not have a price source due to its complete lack of trading, if BFA believes a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), or where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a “significant event” is deemed to occur if BFA determines, in its reasonable business judgment, that an event has occurred after the close of trading for an asset or liability but prior to or at the time of pricing a Fund’s assets or liabilities, is likely to cause a material change to the last exchange closing price or closing market price of one or more assets held by, or liabilities of, a Fund. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that BFA is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset.

BFA’s Rule 2a-5 Committee is responsible for reviewing and approving methodologies by investment type and significant inputs used in the fair valuation of Fund assets or liabilities. In addition, a Fund’s accounting agent assists BFA by periodically endeavoring to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers and regularly evaluating the values assigned to the securities and other assets and liabilities of a Fund. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof.

When determining the price for a Fair Value Asset, BFA will seek to determine the price that a Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction on the date on which the asset or liability is being valued, and does not seek to determine the price a Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. Fair value determinations will be based upon all available factors that BFA deems relevant at the time of the determination, and may be based on analytical values determined by BFA using proprietary or third-party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an investment, one or more fair value methodologies may be used (depending on certain factors, including the asset type). For example, the investment may be initially priced based on the original cost of the investment or, alternatively, using proprietary or third-party models that may rely upon one or more unobservable inputs. Prices of actual, executed or historical transactions in the relevant investment (or comparable instruments) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar instruments, may also be used as a basis for establishing the fair value of an investment.

The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s NAV. As a result, a Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

Each Fund’s annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements.

Generally, ASC 820 and other accounting rules applicable to funds and various assets in which they invest are evolving. Such changes may adversely affect a Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities, to the extent such rules become more stringent, would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value. This may in turn increase the costs associated with selling assets or affect their liquidity due to a Fund’s inability to obtain a third-party determination of fair market value.

Brokerage Transactions

Subject to policies established by the Board, BFA is primarily responsible for the execution of a Fund’s portfolio transactions and the allocation of brokerage. BFA does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Funds, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While BFA generally seeks reasonable trade execution costs, a Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BFA may select a broker based partly upon brokerage or research services provided to BFA and its clients, including a Fund. In return for such services, BFA may cause a Fund to pay a higher commission than other brokers would charge if BFA determines in good faith that the commission is reasonable in relation to the services provided.

In selecting brokers or dealers to execute portfolio transactions, BFA seeks to obtain the best price and most favorable execution for a Fund and may take into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BFA’s knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker’s or dealer’s capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BFA’s knowledge of any actual or apparent operational problems of a broker or dealer. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, thinly traded securities, or other circumstances.

Section 28(e) of the 1934 Act (“Section 28(e)”) permits a U.S. investment adviser, under certain circumstances, to cause an account to pay a broker or dealer a commission for effecting a transaction in securities that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

From time to time, a Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide BFA with research services. FINRA has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research “credits” in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

The Funds anticipate that brokerage transactions involving foreign equity securities generally will be conducted primarily on the principal stock exchanges of the applicable country. Foreign equity securities may be held by the Funds in the form of depositary receipts, or other securities convertible into foreign equity securities. Depositary receipts may be listed on stock

exchanges, or traded in OTC markets in the U.S. or Europe, as the case may be. ADRs, like other securities traded in the U.S., will be subject to negotiated commission rates.

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Funds will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

Under the 1940 Act, persons affiliated with a Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Funds will not deal with affiliated persons and affiliated persons of such affiliated persons in connection with such transactions. The Funds will not purchase securities during the existence of any underwriting or selling group relating to such securities of which BFA, BRIL or any affiliated person (as defined in the 1940 Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3 under the 1940 Act.

Purchases of money market instruments by the Funds are made from dealers, underwriters and issuers. The Funds do not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a “net” basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

BFA may, from time to time, effect trades on behalf of and for the account of the Funds with brokers or dealers that are affiliated with BFA, in conformity with Rule 17e-1 under the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter’s concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

Investment decisions for the Funds and for other investment accounts managed by BFA and the other Affiliates are made independently of each other in light of differing conditions. A variety of factors will be considered in making investment allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings; (ii) tax considerations of an account; (iii) risk or investment concentration parameters for an account; (iv) supply or demand for a security at a given price level; (v) size of available investment; (vi) cash availability and liquidity requirements for accounts; (vii) regulatory restrictions; (viii) minimum investment size of an account; (ix) relative size of account; and (x) such other factors as may be approved by BlackRock’s general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another; (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock; (iii) to develop or enhance a relationship with a client or prospective client; (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock; or (v) to manage or equalize investment performance among different client accounts. BFA and the other Affiliates may deal, trade and invest for their own respective accounts in the types of securities in which the Funds may invest.

Initial public offerings (“IPOs”) of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally,

shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in a Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Funds or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

In certain instances, BFA may find it efficient for purposes of seeking to obtain best execution, to aggregate or “bunch” certain contemporaneous purchases or sale orders of its advisory accounts and advisory accounts of affiliates. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price (except in the case of certain international markets where average pricing is not permitted). While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Funds are concerned, in other cases it could be beneficial to the Funds. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

None of the Funds paid any brokerage commissions to BRIL, an affiliate of BFA, or to any other broker-dealer that is part of the BlackRock group of companies, during the fiscal year ended July 31, 2023.

The Funds' purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BlackRock manages or advises. If purchases or sales of portfolio securities of the Funds and one or more other accounts managed or advised by BlackRock are considered at or about the same time, transactions in such securities are allocated among the Funds and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Funds are concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Funds. BlackRock may deal, trade and invest for its own account in the types of securities in which the Funds may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Funds with brokers

or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Funds will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of the Fund for the fiscal years noted:

Fund	Fiscal Year Ended July 31, 2023	Fiscal Year Ended July 31, 2022
iShares ESG Aware Aggressive Allocation ETF	4%	2%
iShares ESG Aware Conservative Allocation ETF	4%	3%
iShares ESG Aware Growth Allocation ETF	5%	4%

Additional Information Concerning the Trust

Shares. The Trust issues shares of beneficial interests in the funds with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (i) required by the 1940 Act, or (ii) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in such fund’s shares, a holder of shares may be a “control person” of the fund, as defined in Rule 0-1 under the 1940 Act. A fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

In accordance with the Trust's current Agreement and Declaration of Trust (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by the Declaration of Trust or applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or

take other similar actions with, to or into another fund. The Trust or a fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is

required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or a fund, the Trust or a fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in shares of the Fund.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of each Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Distribution of Shares. In connection with each Fund's launch, each Fund was seeded through the sale of one or more Creation Units by each Fund to one or more initial investors. Initial investors participating in the seeding may be Authorized Participants, a lead market maker or other third party investor or an affiliate of each Fund or each Fund’s adviser. Each such initial investor may sell some or all of the shares underlying the Creation Unit(s) held by them pursuant to the registration statement for each Fund (each, a “Selling Shareholder”), which shares have been registered to permit the resale from time to time after purchase. Each Fund will not receive any of the proceeds from the resale by the Selling Shareholders of these shares.

Selling Shareholders may sell shares owned by them directly or through broker-dealers, in accordance with applicable law, on any national securities exchange on which the shares may be listed or quoted at the time of sale, through trading systems, in the OTC market or in transactions other than on these exchanges or systems at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected through brokerage transactions, privately negotiated trades, block sales, entry into options or other derivatives transactions or through any other means authorized by applicable law. Selling Shareholders may redeem the shares held in Creation Unit size by them through an Authorized Participant.

Any Selling Shareholder and any broker-dealer or agents participating in the distribution of shares may be deemed to be “underwriters” within the meaning of Section 2(a)(11) of the 1933 Act, in connection with such sales.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on each Fund's NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the Listing Exchange closes earlier than normal, a Fund may require orders to be placed earlier in the day. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the approximate value of such Creation Unit (estimated using the NAV per share as of February 16, 2024) as of February 22, 2024:

Fund	Shares Per Creation Unit	Approximate Value Per Creation Unit (U.S.$)
iShares ESG Aware Aggressive Allocation ETF	25,000	$1,636,000
iShares ESG Aware Conservative Allocation ETF	25,000	1,237,000
iShares ESG Aware Growth Allocation ETF	25,000	1,469,000
iShares ESG Aware Moderate Allocation ETF	25,000	1,315,000

In its discretion, the Trust reserves the right to increase or decrease the number of a Fund’s shares that constitute a Creation Unit. The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of any Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to each Fund is any day the Fund is open for business, including any day when it satisfies redemption requests as required by Section 22(e) of the 1940 Act. Each Fund is open for business any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, each Listing Exchange observes the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of each Fund generally consists of Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with a Fund's portfolio securities, is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The “Cash Component” is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the NAV per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing a Creation Unit.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of a Fund's portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the relevant Underlying Index.

The Fund Deposit may also be modified to minimize the Cash Component by redistributing the cash to the Deposit Securities portion of the Fund Deposit through “systematic rounding.” The rounding methodology “rounds up” position sizes of securities in the Deposit Securities (which in turn reduces the cash portion). However, the methodology limits the maximum allowed percentage change in weight and share quantity of any given security in the Fund Deposit.

Fund Deposits may also be modified to position a fund towards a forward index rebalance to reflect revisions that account for index additions, deletions, and re-weights.

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security in certain circumstances, including: (i) when instruments are not available in sufficient quantity for delivery; (ii) when instruments are not eligible for transfer through DTC or the clearing process (as discussed below); (iii) when instruments that the Authorized Participant (or an investor on whose behalf the Authorized Participant is acting) are not able to be traded due to a trading restriction; (iv) when delivery of the Deposit Security by the Authorized Participant (or by an investor on whose behalf the Authorized Participant is acting) would be restricted under applicable securities or other local laws; (v) in connection with distribution payments to be made by a Fund; or (vi) in certain other situations.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Procedures for Creation of Creation Units. To be eligible to place orders with the Distributor and to create a Creation Unit of the Funds, an entity must be: (i) a “Participating Party,” i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the “Clearing Process”), a clearing agency that is registered with the SEC, or (ii) a DTC Participant, and must have executed an agreement with the Distributor, with respect to creations and redemptions of Creation Units (“Authorized Participant Agreement”) (discussed below). A member or participant of a clearing agency registered with the SEC which has a written agreement with the Funds or one of their service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units is referred to as an “Authorized Participant.” All shares of the Funds, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant. Creation Units may be purchased only by or through a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Funds or one of their service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the

NAV of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor or its agent an irrevocable order to purchase shares of a Fund, in proper form, generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. The Distributor or its agent will notify BFA and the custodian of such order. The custodian will then provide such information to any appropriate sub-custodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor or its agent by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Funds, immediately available or same day funds estimated by the Funds to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Those placing orders should ascertain the applicable deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time of the Funds. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Funds to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant non-U.S. market are closed may not be accepted. Each Fund's deadline specified above for the submission of purchase orders is referred to as that Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with a Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

Once a Fund has accepted an order, upon the next determination of the NAV of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such NAV. The Distributor or its agent will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

Each Fund reserves the right to reject or revoke a creation order transmitted to it by the Distributor or its agent provided that a rejection or revocation of a creation order does not violate Rule 6c-11 under the Investment Company Act. For example, a Fund may reject or revoke a creation order transmitted to it by the Distributor or its agent if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities is not legally required or would, in the opinion of counsel, be unlawful or have an adverse effect on the Fund or its shareholders (e.g., jeopardize the Fund's tax status); or (v) circumstances outside the control of the Fund, the Distributor or its agent and BFA make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Funds, JPMorgan, the sub-custodian and the Distributor or its agent are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the applicable Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the sub-custodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant sub-custodian or sub-custodians, the Distributor or its agent and BFA shall be notified of such delivery and the applicable Fund will issue and cause the delivery of the Creation Unit. Creation Units are generally issued on a “T+2 basis” (i.e., two Business Days after trade date). Each Fund reserves the right to settle Creation Unit transactions on a basis other than T+2, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law.

To the extent contemplated by an Authorized Participant Agreement with the Distributor, each Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Fund Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant's delivery and maintenance of collateral as set forth in the handbook for Authorized Participants. The Trust may use such collateral at any time to buy Deposit Securities for the Funds. Such collateral must be delivered no later than the time specified by a Fund or its custodian on the contractual settlement date. Information concerning the Funds' current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Authorized Participant Agreement will permit the Funds to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such securities and the collateral including, without limitation, liability for related brokerage, borrowings and other charges.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Funds reserve the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by each Fund and the Fund's determination shall be final and binding.

Costs Associated with Creation Transactions.

A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. Under an ETF Services Agreement, the Funds have retained BRIL, an affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units of the Funds (“ETF Services”). BRIL will receive from an Authorized Participant a standard transaction fee on each creation order, which consists of (1) a fee for providing the ETF Services (the “ETF Servicing Fee”) and (2) transfer, processing and other transaction costs charged by a Fund custodian in connection with the issuance of Creation Units for such creation order (“Custody Transaction Costs”). BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the applicable Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being purchased, which amount will vary among different Funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a Fund’s Creation Basket, among other variables. The actual Custody Transaction Costs vary per order based on the number of trades, underlying markets and settlement locations associated with the issuance of a Creation Unit. The following table sets forth, for each Fund, either the actual creation transaction fee that was charged on October 31, 2023 or an estimate of the creation transaction fee that would have been charged if the Fund had issued a Creation Unit on that date. The actual fee that was or would have been charged to an Authorized Participant in connection with a creation order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.

If a purchase consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth each Fund's actual or estimated creation transaction fee, as applicable, as of October 31, 2023 and maximum additional charge (as described above):

Fund	Standard Creation Transaction Fee	Maximum Additional Charge for Creations*
iShares ESG Aware Aggressive Allocation ETF	$156.25 **	3.0 %
iShares ESG Aware Conservative Allocation ETF	156.25 **	3.0 %
iShares ESG Aware Growth Allocation ETF	156.25 **	3.0 %
iShares ESG Aware Moderate Allocation ETF	156.25 **	3.0 %

Redemption of Creation Units. Shares of a Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor or its agent and only on a Business Day. The Funds will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

Each Fund generally redeems Creation Units for Fund Securities (as defined below). Please see the Cash Redemption Method section below and the following discussion summarizing the in-kind method for further information on redeeming Creation Units of the Funds.

Each Fund publishes the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable to redemption requests received in proper form (as defined below) on that day (“Fund Securities” or “Redemption Basket”), and an amount of cash (the “Cash Amount,” as described below) in order to effect redemptions of Creation Units of a Fund. Such Fund Securities and Cash Amount will remain in effect until such time as the next announced composition of the Fund Securities and Cash Amount is made available. The Fund Securities and Cash Amount are subject to possible amendment or correction. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

Unless cash redemptions are available or specified for a Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus the Cash Amount, which is an amount equal to the difference between the NAV of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below).

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security in certain circumstances, including: (i) when the delivery of a Fund Security to the Authorized Participant (or to an investor on whose behalf the Authorized Participant is acting) would be restricted under applicable securities or other local laws or due to a trading restriction; (ii) when the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws; (iii) when the delivery of a Fund Security to the Authorized Participant would result in unfavorable tax treatment; (iv) when a Fund Security cannot be settled or otherwise delivered in time to facilitate an in-kind redemption; or (v) in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. Each Fund generally redeems Creation Units for Fund Securities, but each Fund reserves the right to utilize a cash option for redemption of Creation Units. Each Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV. The Redemption Basket may also be modified to minimize the Cash Component by redistributing the cash to the Fund Securities portion of the Redemption Basket through systematically rounding. The rounding methodology allows position sizes of securities in the Fund Securities to be “rounded up,” while limiting the maximum allowed percentage change in weight and share quantity of any given security in the Redemption Basket. Redemption Baskets may also be modified to position a fund towards a forward index
rebalance to reflect revisions that account for index additions, deletions, and re-weights.

Cash Redemption Method. Although the Trust does not generally permit partial or full cash redemptions of Creation Units of its funds, when partial or full cash redemptions of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer.

Costs Associated with Redemption Transactions.

A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the relevant Fund. As described above, under an ETF Services Agreement, the Funds have retained BRIL, an affiliate of BFA, to perform certain ETF Services. BRIL will receive from an Authorized Participant a standard transaction fee on each redemption order, which consists of (1) the ETF Servicing Fee and (2) Custody Transaction Costs. BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the applicable Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being redeemed, which amount will vary among different Funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a Fund’s Redemption Basket, among other variables. The actual Custody Transaction Costs vary per order based on the number of trades, underlying markets, and settlement locations associated with the redemption of a Creation Unit. The following table sets forth, for each Fund, either the actual redemption transaction fee that was charged on October 31, 2023 or an estimate of the redemption transaction fee that would have been charged if the Fund had redeemed a Creation Unit on that date. The actual fee that was or would have been charged to an Authorized Participant in connection with a redemption order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.

If a redemption consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth each Fund's actual or estimated redemption transaction fee, as applicable, as of October 31, 2023 and maximum additional charge (as described above):

Fund	Standard Redemption Transaction Fee	Maximum Additional Charge for Redemptions*
iShares ESG Aware Aggressive Allocation ETF	$156.25 **	2.0 %
iShares ESG Aware Conservative Allocation ETF	156.25 **	2.0 %
iShares ESG Aware Growth Allocation ETF	156.25 **	2.0 %
iShares ESG Aware Moderate Allocation ETF	156.25 **	2.0 %

As a percentage of the net asset value per Creation Unit.

Placement of Redemption Orders. Redemption requests for Creation Units of the Funds must be submitted to the Distributor or its agent by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. On days when the Listing Exchange closes earlier than normal, a Fund may require orders to redeem Creation Units to be placed earlier that day. Investors, other than Authorized Participants, are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Funds to the Distributor or its agent in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor's broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Funds' transfer agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if: (i) an Authorized Participant has transferred or caused to be transferred to the Funds' transfer agent the Creation Unit redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day on which the redemption request is submitted; (ii) a request in form satisfactory to the applicable Fund is received by the Distributor or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above; and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed.

Upon receiving a redemption request, the Distributor or its agent shall notify the applicable Fund and the Fund's transfer agent of such redemption request. The tender of an investor's shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Authorized Participant, whether on its own account or acting on behalf of a Beneficial Owner, must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the portfolio securities are customarily traded, to which account such portfolio securities will be delivered.

Deliveries of redemption proceeds by each Fund are generally made within two Business Days (i.e., “T+2”). Each Fund reserves the right to settle redemption transactions on a basis other than T+2, if necessary or appropriate under the circumstances and compliant with applicable law. If a Fund includes a foreign investment in its basket, and if a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming Authorized Participants prevents timely delivery of the foreign investment in response to a redemption request, the Fund may delay delivery of the foreign investment more than seven days if the Fund delivers the foreign investment as soon as practicable, but in no event later than 15 days.

To the extent contemplated by an Authorized Participant’s agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to a Fund, at or prior to the time specified by a Fund or its custodian on the Business Day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral as set forth in the Handbook for Authorized Participants. Such collateral must be delivered no later than the time specified by a Fund or its custodian on the Business Day after the date of submission of such redemption request and shall be held by JPMorgan and marked-to-market daily. The fees of JPMorgan and any sub-custodians in respect of the delivery, maintenance and redelivery of the collateral shall be payable by the Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire shares of the Funds at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Funds of purchasing such shares, plus the value of the Cash Amount, and the value of the collateral together with liability for related brokerage and other charges.

The right of redemption may be suspended or the date of payment postponed with respect to any Fund: (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund's portfolio securities or determination of its NAV is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Custom Baskets. Creation and Redemption baskets may differ and each Fund may accept “custom baskets.” A custom basket may include any of the following: (i) a basket that is composed of a non-representative selection of a Fund's portfolio holdings; (ii) a representative basket that is different from the initial basket used in transactions on the same business day; or (iii) a basket that contains bespoke cash substitutions for a single Authorized Participant. Each Fund has adopted policies and procedures that govern the construction and acceptance of baskets, including heightened requirements for certain types of custom baskets. Such policies and procedures provide the parameters for the construction and acceptance of custom baskets that are in the best interests of a Fund and its shareholders, establish processes for revisions to, or deviations from, such parameters, and specify the titles and roles of the employees of BFA who are required to review each custom basket for compliance with those parameters. In addition, when constructing custom baskets for redemptions, the tax efficiency of a Fund may be taken into account. The policies and procedures distinguish among different types of custom baskets that may be used for each Fund and impose different requirements for different types of custom baskets in order to seek to mitigate against potential risks of conflicts and/or overreaching by an Authorized Participant. BlackRock has established a governance process to oversee basket compliance for the Funds, as set forth in each Fund's policies and procedures.

Taxation on Creations and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the IRS may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal income tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of a Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to a Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific U.S. federal, state, local and non-U.S. tax consequences of investing in a Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect. References to the Funds will also generally apply to the Underlying Funds as well.

Regulated Investment Company Qualifications. Each Fund intends to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, each Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of each Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive at least 90% of their income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of each Fund's taxable year, (a) at least 50% of the market value of each Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of each Fund's total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

A Fund may be able to cure a failure to derive at least 90% of its income from the sources specified above or a failure to diversify its holdings in the manner described above by paying a tax and/or by disposing of certain assets. If, in any taxable year, a Fund fails one of these tests and does not timely cure the failure, that Fund will be taxed in the same manner as an ordinary corporation and distributions to its shareholders will not be deductible by that Fund in computing its taxable income.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. A Fund's investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, a Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, a Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. A Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If a Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, a Fund may decide to retain a portion of its income or gains if the Fund determines that doing so is in the interest of its shareholders. Each Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If a Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. A Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus at least 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by a Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. Each Fund intends

to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax. Long-term capital distributions from the Underlying Funds paid in December or, in certain cases, January in satisfaction of this rule will be subject to potential distribution by the Funds in the following calendar year.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

In the event that a Fund were to experience an ownership change as defined under the Internal Revenue Code, the loss carryforwards and other favorable tax attributes of a Fund, if any, may be subject to limitation.

The following Funds had net capital loss carryforwards as set forth in the table below as of July 31, 2023, the tax year-end for the Funds listed:

Fund	Non-Expiring Capital Loss Carryforward
iShares ESG Aware Aggressive Allocation ETF	$120,188
iShares ESG Aware Conservative Allocation ETF	87,819
iShares ESG Aware Growth Allocation ETF	84,368
iShares ESG Aware Moderate Allocation ETF	58,991

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

Each Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if a Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that a Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of a Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below. Because the Fund is expected to invest in an Underlying Fund, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of a Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Distributions in excess of a Fund’s minimum distribution requirements, but not in excess of a Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount.

A 3.8% U.S. federal Medicare contribution tax is imposed on net investment income, including, but not limited to, interest, dividends, and net gain from investments, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of (i) the excess of post-October foreign currency and passive foreign investment company (“PFIC”) losses over post-October foreign currency and PFIC gains and (ii) the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of a Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by a Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option or contract to acquire substantially identical shares, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the

same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Backup Withholding. In certain cases, a Fund will be required to withhold at a 24% rate and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to backup withholding by the IRS; (iii) has failed to certify to a Fund that such shareholder is not subject to backup withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder's U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of each Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of a given Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, that Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If a Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to a Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

Taxation of Certain Derivatives. An Underlying Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require an Underlying Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause an Underlying Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Underlying Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of an Underlying Fund as a RIC.

An Underlying Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by an Underlying Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in an Underlying Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by an Underlying Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by an Underlying Fund.

As a result of entering into swap contracts, an Underlying Fund may make or receive periodic net payments. An Underlying Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if an Underlying Fund has been a party to the swap for more than one year). With respect to certain types of swaps, an Underlying Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by a Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent a Fund receives qualified dividend income on the securities it holds and a Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Under current IRS guidance, the U.S. has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the U.K. and Venezuela. Substitute payments received by a Fund for securities lent out by a Fund will not be qualified dividend income.

A dividend from a Fund will not be treated as qualified dividend income to the extent that: (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or a Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) a Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by a Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. However, for tax years beginning after December 31, 2017 and before January 1, 2026, a non-corporate taxpayer who is a direct REIT shareholder may claim a 20% “qualified business income” deduction for ordinary REIT dividends, and a RIC may report dividends as eligible for this deduction to the extent the RIC’s income is derived from ordinary REIT dividends (reduced by allocable RIC expenses). A shareholder may treat the dividends as such provided the RIC and the shareholder satisfy applicable holding period requirements. Distributions by a Fund of its net short-term capital gains will be taxable as ordinary income.

Corporate Dividends Received Deduction. Dividends paid by a Fund that are attributable to dividends received by the Fund from the Underlying Funds and that are attributable to dividends paid by U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at the Fund level, the Underlying Fund level and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Funds serve to block unrelated business taxable income (“UBTI”) from being realized by their tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize UBTI by virtue of its investment in a Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by an Underlying Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may: (i) constitute taxable income, as UBTI for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund or Underlying Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has UBTI for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

A Fund tries to avoid investing in REITs that are expected to generate excess inclusion income, but a Fund may not always be successful in doing so. Because information about a REIT’s investments may be inadequate or inaccurate, or because a REIT may change its investment program, a Fund may not be successful in avoiding the consequences described above. Avoidance of investments in REITs that generate excess inclusion income may require a Fund to forego otherwise attractive investment opportunities.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time an Underlying Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time an Underlying Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S. currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless an Underlying Fund was to elect otherwise.

If your Fund shares are loaned pursuant to securities lending arrangements, you may lose the ability to use any non-U.S. tax credits passed through by a Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Regarding a short sale with respect to shares of a Fund, substitute payments made to the lender of such shares may not be deductible under certain circumstances. Consult your financial intermediary or tax advisor. The Underlying Funds, if invested in non-U.S. positions, may be subject to non-U.S. income taxes and non-U.S. financial transactions taxes. Each Underlying Fund that is permitted to do so may elect to “pass through” to its investors, including the Funds, the amount of non-U.S. income taxes paid by the Underlying Fund. If more than 50% of the total assets of an Underlying Fund at the close of a year consist of non-U.S. stocks or securities (generally for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”) (and 50% of the total assets of the Fund at the close of the year consists of non-U.S. securities, or, at the close of each quarter, shares of Underlying Funds), the Funds may be eligible to elect to “pass through” such amounts to their stockholders and may do so, depending upon circumstances.

Passive Foreign Investment Companies. If an Underlying Fund purchases shares in PFICs, it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If an Underlying Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, an Underlying Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to an Underlying Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, an Underlying Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain.

Alternatively, an Underlying Fund may make a mark-to-market election that would result in an Underlying Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, an Underlying Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by an Underlying Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, an Underlying Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. An Underlying Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

An Underlying Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement,

but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by a Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by a Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN or IRS Form W-8BEN-E certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the U.S. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable form may be subject to backup withholding at the appropriate rate.

Properly-reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the Fund’s “qualified net interest income” (generally, the Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder or partner, reduced by expenses that are allocable to such income) or (ii) are paid in respect of the Fund’s “qualified short-term capital gains” (generally, the excess of the Fund’s net short-term capital gain over the Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, IRS Form W-8BEN-E or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

Special rules may apply to a foreign shareholder receiving a Fund distribution if at least 50% of the Fund's assets consist of interests in U.S. real property interests, including certain REITs and U.S. real property holding corporations (as defined in the Internal Revenue Code and Treasury regulations). Fund distributions that are attributable to gain from the disposition of a U.S. real property interest will be taxable as ordinary dividends and subject to withholding at a 30% or lower treaty rate if the foreign shareholder held no more than 5% of the Fund's shares at any time during the one-year period ending on the date of the distribution. If the foreign shareholder held at least 5% of the Fund's shares, the distribution would be treated as income effectively connected with a trade or business within the U.S. and the foreign shareholder would be subject to withholding tax at a rate of 21% and would generally be required to file a U.S. federal income tax return.

Similar consequences would generally apply to a foreign shareholder's gain on the sale of Fund shares unless the Fund is domestically controlled (meaning that more than 50% of the value of the Fund's shares is held by U.S. shareholders) or the foreign shareholder owns no more than 5% of the Fund's shares at any time during the five-year period ending on the date of sale. Finally, a domestically controlled Fund may be required to recognize a portion of its gain on the in-kind distribution of certain U.S. real property interests. Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in the Fund.

The rules laid out in the previous two paragraphs, other than the withholding rules, will apply notwithstanding a Fund’s or an Underlying Fund's participation in a wash sale transaction or its payment of a substitute dividend.

Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in a Fund.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items paid to: (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS

information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to: (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information concerning their account holders, or (ii) in the event an intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

Open-End Fund Proxy Voting Policy

Procedures Governing Delegation of Proxy Voting to Fund Advisers

Effective Date: August 1, 2021

Last Review Date: August 25, 2023

Open-End Mutual Funds (including money market funds)

Exchange-Traded Funds

Objective and Scope

Set forth below is the Open-End Fund Proxy Voting Policy.

Policy/Document Requirements and Statements

The Boards of Trustees/Directors (“Directors”) of open-end funds (the “Funds”) advised by BlackRock Fund Advisors or BlackRock Advisors, LLC (“BlackRock”), have the responsibility for the oversight of voting proxies relating to portfolio securities of the Funds, and have determined that it is in the best interests of the Funds and their shareholders to delegate the responsibility to vote proxies to BlackRock, subject to the principles outlined in this Policy, as part of BlackRock’s authority to manage, acquire and dispose of account assets, all as contemplated by the Funds’ respective investment management agreements.

BlackRock has adopted guidelines and procedures (together and as from time to time amended, the “BlackRock proxy voting guidelines”) governing proxy voting by accounts managed by BlackRock.

BlackRock will cast votes on behalf of each of the Funds on specific proxy issues in respect of securities held by each such Fund (or may refrain from voting) in accordance with the BlackRock proxy voting guidelines.

BlackRock will report on an annual basis to the Directors on (1) a summary of the proxy voting process as applicable to the Funds in the preceding year together with a representation that all votes were in accordance with the BlackRock proxy voting guidelines, and (2) any changes to the BlackRock proxy voting guidelines that have not previously been reported.

Introduction to BlackRock

BlackRock’s purpose is to help more and more people experience financial well-being. We manage assets on behalf of institutional and individual clients, across a full spectrum of investment strategies, asset classes, and regions. Our client base includes pension plans, endowments, foundations, charities, official institutions, insurers, and other financial institutions, as well as individuals around the world.

Philosophy on investment stewardship

As part of our fiduciary duty to our clients, we consider it one of our responsibilities to promote sound corporate governance as an informed, engaged shareholder on their behalf. At BlackRock, this is the responsibility of the BlackRock Investment Stewardship (BIS) team.

In our experience, sound governance is critical to the success of a company, the protection of investors’ interests, and long-term financial value creation. We take a constructive, long-term approach with companies and seek to understand how they are managing the drivers of risk and financial value creation in their business models. We have observed that well-managed companies will effectively evaluate and address risks and opportunities relevant to their businesses, which supports durable, long-term financial value creation. As one of many minority shareholders, BlackRock cannot – and does not try to – direct a company’s strategy or its implementation.

Shareholder rights

We believe that there are certain fundamental rights attached to shareholding. Shareholders should have the right to:

•

Elect, remove, and nominate directors, approve the appointment of the auditor, and amend the corporate charter or by-laws.

•

Vote on key board decisions that are material to the protection of their investment, including but not limited to, changes to the purpose of the business, dilution levels and pre-emptive rights, and the distribution of income and capital structure.

•

Access sufficient and timely information on material governance, strategic, and business matters to make informed decisions.

In our view, shareholder voting rights should be proportionate to economic ownership—the principle of “one share, one vote” helps to achieve this balance.

Consistent with these shareholder rights, BlackRock monitors and provides feedback to companies in our role as stewards of our clients’ assets. Investment stewardship is how we use our voice as an investor to promote sound corporate governance and business practices that support the ability of companies to deliver long-term financial performance for our clients. We do this through engagement with companies, proxy voting on behalf of those clients who have given us authority, and participating in market-level dialogue to improve corporate governance standards.

Engagement is an important mechanism for providing feedback on company practices and disclosures, particularly where our observations indicate that they could be enhanced to support a company’s ability to deliver financial performance. Similarly, it provides us with an opportunity to hear directly from company boards and management on how they believe their actions are aligned with the long-term economic interests of shareholders. Engagement with companies may also inform our proxy voting decisions.

As a fiduciary, we vote in the long-term economic interests of our clients. Generally, we support the recommendations of the board of directors and management. However, there may be instances where we vote against the election of directors or other management proposals, or support shareholder proposals. For instance, we may vote against management recommendations where we are concerned that the board may not be acting in the long-term economic interests of shareholders, or disclosures do not provide sufficient information to assess how material, strategic risks and opportunities are being managed. Our regional proxy voting guidelines are informed by our market-specific approach and standards of corporate governance best practices.

Key Themes

While accepted standards and norms of corporate governance can differ between markets, in our experience, there are certain globally-applicable fundamental elements of governance that contribute to a company’s ability to create long-term financial value for shareholders. These global themes are set out in this overarching set of principles (the “Principles”), which are anchored in transparency and accountability. At a minimum, it is our view that companies should observe the accepted

A-4

corporate governance standards in their domestic market and we ask that, if they do not, they explain how their approach better supports durable, long-term financial value creation.

These Principles cover seven key subjects:

•

Boards and directors

•

Auditors and audit-related issues

•

Capital structure, mergers, asset sales, and other special transactions

•

Executive compensation

•

Material sustainability-related risks and opportunities

•

Other corporate governance matters and shareholder protections

•

Shareholder proposals

Our regional and market-specific voting guidelines explain how these Principles inform our voting decisions in relation to common ballot items for shareholder meetings in those markets. Alongside the Principles and regional voting guidelines, BIS publishes our engagement priorities which reflect the five themes on which we most frequently engage companies, where they are relevant, as these can be a source of material business risk or opportunity. Collectively, these BIS policies set out the core elements of corporate governance that guide our investment stewardship efforts globally and within each market, including when engaging with companies and voting at shareholder meetings. The BIS policies are applied on a case-by-case basis, taking into consideration the context within which a company is operating.

Boards and directors

We believe that an effective and well-functioning board that has appropriate governance structures to facilitate oversight of a company's management and strategic initiatives is critical to the long-term financial success of a company and the protection of shareholders’ economic interests. In our view, a strong board can be a competitive advantage to a company, providing valuable oversight of and perspectives to management on the most important decisions in support of long-term financial performance. As part of their responsibilities, board members have a fiduciary duty to shareholders to oversee the strategic direction, operations, and risk management of a company. For this reason, BIS sees engagement with and the election of directors as one of our most important responsibilities. Disclosure of material risks that may affect a company’s long-term strategy and financial value creation, including material sustainability-related factors when relevant, is essential for shareholders to appropriately understand and assess how effectively management is identifying, managing, and mitigating such risks.

The board should establish and maintain a framework of robust and effective governance mechanisms to support its oversight of the company’s strategy and operations consistent with the long-term economic interests of investors. There should be clear descriptions of the role of the board and the committees of the board and how directors engage with and oversee management. We look to the board to articulate the effectiveness of these mechanisms in overseeing the management of business risks and opportunities and the fulfillment of the company’s purpose and strategy.

Where a company has not adequately disclosed and demonstrated that its board has fulfilled these corporate governance and risk oversight responsibilities, we will consider voting against the election of directors who, on our assessment, have particular responsibility for the issues. We assess director performance on a case-by-case basis and in light of each company’s circumstances, taking into consideration their governance, business practices that support durable, long-term financial value creation, and performance. Set out below are ways in which boards and directors can demonstrate a commitment to acting in the long-term economic interests of all shareholders.

Regular accountability through director elections

It is our view that directors should stand for election on a regular basis, ideally annually. In our experience, annual director elections allow shareholders to reaffirm their support for board members and/or hold them accountable for their decisions in a timely manner. When board members are not elected annually, in our experience, it is good practice for boards to have a rotation policy to ensure that, through a board cycle, all directors have had their appointment re-confirmed, with a proportion of directors being put forward for election at each annual general meeting.

Effective board composition

Regular director elections also give boards the opportunity to adjust their composition in an orderly way to reflect developments in the company’s strategy and the market environment. In our view, it is beneficial for new directors to be

A-5

brought onto the board periodically to refresh the group’s thinking, while supporting both continuity and appropriate succession planning. We consider the average overall tenure of the board, and seek a balance between the knowledge and experience of longer-serving directors and the fresh perspectives of directors who joined more recently. We encourage companies to regularly review the effectiveness of their board (including its size), and assess directors nominated for election in the context of the composition of the board as a whole. In our view, the company’s assessment should consider a number of factors, including each director’s independence and time commitments, as well as the diversity and relevance of director experiences and skillsets, and how these factors may contribute to the financial performance of the company.

Similarly, there should be a sufficient number of independent directors, free from conflicts of interest or undue influence from connected parties, to ensure objectivity in the decision-making of the board and its ability to oversee management. Common impediments to independence may include but are not limited to:

•

Current or recent employment at the company or a subsidiary

•

Being, or representing, a shareholder with a substantial shareholding in the company

•

Interlocking directorships

•

Having any other interest, business, or other relationship which could, or could reasonably be perceived to, materially interfere with a director’s ability to act in the best interests of the company and shareholders.

In our experience, boards are most effective at overseeing and advising management when there is a senior, independent board leader. This director may chair the board, or, where the chair is also the CEO (or is otherwise not independent), be designated as a lead independent director. The role of this director is to enhance the effectiveness of the independent members of the board through shaping the agenda, ensuring adequate information is provided to the board, and encouraging independent director participation in board deliberations. The lead independent director or another appropriate director should be available to meet with shareholders in those situations where an independent director is best placed to explain and contextualize a company’s approach.

There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors, or require additional focus. It is our view that objective oversight of such matters is best achieved when the board forms committees comprised entirely of independent directors. In many markets, these committees of the board specialize in audit, director nominations, and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one involving a related party, or to investigate a significant adverse event.

When nominating directors to the board, we look to companies to provide sufficient information on the individual candidates so that shareholders can assess the capabilities and suitability of each individual nominee and their fit within overall board composition. These disclosures should give an understanding of how the collective experience and expertise of the board, as well as the particular skill-sets of individual directors, aligns with the company’s long-term strategy and business model. Highly qualified, engaged directors with professional characteristics relevant to a company’s business and strategy enhance the ability of the board to add value and be the voice of shareholders in board discussions.

It is in this context that we are interested in diversity in the board room. We see it as a means to promoting diversity of thought and avoiding “group think” when the board advises and oversees management. This position is based on our view that diversity of perspective and thought – in the board room, in the management team, and throughout the company – leads to better long-term economic outcomes for companies. Academic research has revealed correlations between specific dimensions of diversity and effects on decision-making processes and outcomes.1 In our experience, greater diversity in the board room can contribute to more robust discussions and more innovative and resilient decisions. Over time, greater diversity in the board room can also promote greater diversity and resilience in the leadership team, and the workforce more broadly. That diversity can enable companies to develop businesses that better address the needs of the customers and communities they serve.

We ask boards to disclose how diversity is considered in board composition, including professional characteristics, such as a director’s industry experience, specialist areas of expertise and geographic location; as well as demographic characteristics such as gender, race/ethnicity, and age.

We look to understand a board’s diversity in the context of a company’s domicile, market capitalization, business model, and strategy. Increasingly, we see the most effective boards nominating directors from diverse backgrounds which helps ensure boards can more effectively understand the company's customers, employees, and communities. We note that in many markets, policymakers have set board gender diversity goals which we may discuss with companies, particularly if there is a

For a discussion on the different impacts of diversity see: McKinsey, “Diversity Wins: How Inclusion Matters,” May 2022; Harvard Business Review, “Diverse Teams Feel Less Comfortable – and That’s Why They Perform Better,” September 2016; “Do Diverse Directors Influence DEI Outcomes,” September 2022.

risk their board composition may be misaligned. Self-identified board demographic diversity can usefully be disclosed in aggregate, consistent with local law. We encourage boards to aspire to meaningful diversity of membership, while recognizing that building a strong, diverse board can take time.

Sufficient capacity

As the role and expectations of a director are increasingly demanding, directors must be able to commit an appropriate amount of time to board and committee matters. It is important that directors have the capacity to meet all of their responsibilities - including when there are unforeseen events – and therefore, they should not take on an excessive number of roles that would impair their ability to fulfill their duties.

Auditors and audit-related issues

BlackRock recognizes the critical importance of financial statements, which should provide a true and fair picture of a company’s financial condition. Accordingly, the assumptions made by management and reviewed by the auditor in preparing the financial statements should be reasonable and justified.

The accuracy of financial statements, inclusive of financial and non-financial information as required or permitted under market-specific accounting rules, is of paramount importance to BlackRock. Investors increasingly recognize that a broader range of risks and opportunities have the potential to materially impact financial performance. Over time, we anticipate investors and other users of company reporting will increasingly seek to understand and scrutinize the assumptions underlying financial statements, particularly those that pertain to the impact of the transition to a low-carbon economy on a company’s business model and asset mix. We recognize that this is an area of evolving practice and note that international standards setters, such as the International Financial Reporting Standards (IFRS) Board and the International Auditing and Assurance Standards Board (IAASB), continue to develop their guidance to companies.2

In this context, audit committees, or equivalent, play a vital role in a company’s financial reporting system by providing independent oversight of the accounts, material financial and, where appropriate to the jurisdiction, non-financial information and internal control frameworks. Moreover, in the absence of a dedicated risk committee, these committees can provide oversight of Enterprise Risk Management systems.3 In our view, effective audit committee oversight strengthens the quality and reliability of a company’s financial statements and provides an important level of reassurance to shareholders.

We hold members of the audit committee or equivalent responsible for overseeing the management of the audit function. Audit committees or equivalent should have clearly articulated charters that set out their responsibilities and have a rotation plan in place that allows for a periodic refreshment of the committee membership to introduce fresh perspectives to audit oversight. We recognize that audit committees will rely on management, internal audit, and the independent auditor in fulfilling their responsibilities but look to committee members to demonstrate they have relevant expertise to monitor and oversee the audit process and related activities.

We take particular note of unexplained changes in reporting methodology, cases involving significant financial restatements, or ad hoc notifications of material financial weakness. In this respect, audit committees should provide timely disclosure on the remediation of Key and Critical Audit Matters identified either by the external auditor or internal audit function.

The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, it is important that auditors are, and are seen to be, independent. Where an audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should have in place a procedure for assessing annually the independence of the auditor and the quality of the external audit process.

Comprehensive disclosure provides investors with a sense of the company’s long-term operational risk management practices and, more broadly, the quality of the board’s oversight. The audit or risk committee, should periodically review the company’s risk assessment and risk management policies and the significant risks and exposures identified by management, the internal auditors or the independent auditors and management’s steps to address them. In the absence of detailed disclosures, we may reasonably conclude that companies are not adequately managing risk.

Capital structure, mergers, asset sales, and other special transactions

The capital structure of a company is critical to shareholders as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emptive rights are a key protection for shareholders against the dilution of their interests.

Effective voting rights are basic rights of share ownership and a core principle of effective governance. Shareholders, as the residual claimants, have the strongest interest in protecting the financial value of the company, and voting rights should match economic exposure, i.e. one share, one vote.

In principle, we disagree with the creation of a share class with equivalent economic exposure and preferential, differentiated voting rights. In our view, this structure violates the fundamental corporate governance principle of proportionality and results in a concentration of power in the hands of a few shareholders, thus disenfranchising other shareholders and amplifying any potential conflicts of interest. However, we recognize that in certain markets, at least for a period of time, companies may have a valid argument for listing dual classes of shares with differentiated voting rights. In our view, such companies should review these share class structures on a regular basis or as company circumstances change. Additionally, they should seek shareholder approval of their capital structure on a periodic basis via a management proposal at the company’s shareholder meeting. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.

In assessing mergers, asset sales, or other special transactions, BlackRock’s primary consideration is the long-term economic interests of our clients as shareholders. Boards proposing a transaction should clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it can enhance long-term shareholder value. We find long-term investors like our clients typically benefit when proposed transactions have the unanimous support of the board and have been negotiated at arm’s length. We may seek reassurance from the board that the financial interests of executives and/or board members in a given transaction have not adversely affected their ability to place shareholders’ interests before their own. Where the transaction involves related parties, the recommendation to support should come from the independent directors, a best practice in most markets, and ideally, the terms should have been assessed through an independent appraisal process. In addition, it is good practice that it be approved by a separate vote of the non-conflicted parties.

As a matter of sound governance practice, shareholders should have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders’ ability to sell their shares are contrary to basic property rights. Such mechanisms can serve to protect and entrench interests other than those of the shareholders. In our view, shareholders are broadly capable of making decisions in their own best interests. We encourage any so-called “shareholder rights plans” proposed by a board to be subject to shareholder approval upon introduction and periodically thereafter.

Executive compensation

In most markets, one of the most important roles for a company’s board of directors is to put in place a compensation structure that incentivizes and rewards executives appropriately. There should be a clear link between variable pay and operational and financial performance. Performance metrics should be stretching and aligned with a company’s strategy and business model. BIS does not have a position on the use of sustainability-related criteria in compensation structures, but in our view, where companies choose to include these components, they should be adequately disclosed, material to the company’s strategy, and as rigorous as other financial or operational targets. Long-term incentive plans should encompass timeframes that 1) are distinct from annual executive compensation structures and metrics, and 2) encourage the delivery of strong financial results over a period of years. Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their employment. Finally, pension contributions and other deferred compensation arrangements should be reasonable, in light of market practices.

We are not supportive of one-off or special bonuses unrelated to company or individual performance. Where discretion has been used by the compensation committee or its equivalent, we expect disclosure relating to how and why the discretion was used, and how the adjusted outcome is aligned with the interests of shareholders. We acknowledge that the use of peer group evaluation by compensation committees can help ensure competitive pay; however, we are concerned when the rationale for increases in total compensation at a company is solely based on peer benchmarking, rather than a rigorous measure of outperformance. We encourage companies to clearly explain how compensation outcomes have rewarded performance.

A-8

We encourage boards to consider building clawback provisions into incentive plans such that companies could clawback compensation or require executives to forgo awards when compensation was based on faulty financial statements or deceptive business practices. We also favor recoupment from or the foregoing of the grant of any awards by any senior executive whose behavior caused material financial harm to shareholders, material reputational risk to the company, or resulted in a criminal investigation, even if such actions did not ultimately result in a material restatement of past results.

Non-executive directors should be compensated in a manner that is commensurate with the time and effort expended in fulfilling their professional responsibilities. Additionally, these compensation arrangements should not risk compromising directors’ independence or aligning their interests too closely with those of the management, whom they are charged with overseeing.

We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. BIS may signal concerns through not supporting management’s proposals to approve compensation, where they are on the agenda. We may also vote against members of the compensation committee or equivalent board members for poor compensation practices or structures.

Material sustainability-related risks and opportunities

It is our view that well-managed companies will effectively evaluate and manage material sustainability-related risks and opportunities relevant to their businesses. As with all risks and opportunities in a company's business model, appropriate oversight of material sustainability considerations is a core component of having an effective governance framework, which supports durable, long-term financial value creation.

Robust disclosure is essential for investors to effectively evaluate companies’ strategy and business practices related to material sustainability-related risks and opportunities. Long-term investors like our clients can benefit when companies demonstrate that they have a resilient business model through disclosures that cover governance, strategy, risk management, and metrics and targets, including industry-specific metrics. The International Sustainability Standards Board (ISSB) standards, IFRS S1 and S2,4 provide companies with a useful guide to preparing this disclosure. The standards build on the Task Force on Climate-related Financial Disclosures (TCFD) framework and the standards and metrics developed by the Sustainability Accounting Standards Board (SASB), which have converged under the ISSB. We recognize that companies may phase in reporting aligned with the ISSB standards over several years. We also recognize that some companies may report using different standards, which may be required by regulation, or one of a number of voluntary standards. In such cases, we ask that companies highlight the metrics that are industry- or company-specific.

We note that climate and other sustainability-related disclosures often require companies to collect and aggregate data from various internal and external sources. We recognize that the practical realities of data collection and reporting may not line up with financial reporting cycles and companies may require additional time after their fiscal year-end to accurately collect, analyze, and report this data to investors.

That said, to give investors time to assess the data, we encourage companies to produce climate and other sustainability-related disclosures sufficiently in advance of their annual meeting, to the best of their abilities.

Companies may also choose to adopt or refer to guidance on sustainable and responsible business conduct issued by supranational organizations such as the United Nations or the Organization for Economic Cooperation and Development. Further, industry initiatives on managing specific operational risks may provide useful guidance to companies on best practices and disclosures. We find it helpful to our understanding of investment risk when companies disclose any relevant global climate and other sustainability-related standards adopted, the industry initiatives in which they participate, any peer group benchmarking undertaken, and any assurance processes to help investors understand their approach to sustainable and responsible business practices. We will express any concerns through our voting where a company’s actions or disclosures do not seem adequate in light of the materiality of the business risks.

Climate and nature-related risk

While companies in various sectors and geographies may be affected differently by climate-related risks and opportunities, the low-carbon transition is an investment factor that can be material for many companies and economies around the globe.

4 The objective of IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information is to require an entity to disclose information about its sustainability-related risks and opportunities that is useful to primary users of general-purpose financial reports in making decisions relating to providing resources to the entity. The objective of IFRS S2 Climate-related Disclosures is to require an entity to disclose information about its climate-related risks and opportunities that is useful to primary users of general-purpose financial reports in making decisions relating to providing resources to the entity.

A-9

We seek to understand, from company disclosures and engagement, the strategies companies have in place to manage material risks to, and opportunities for, their long-term business model associated with a range of climate-related scenarios, including a scenario in which global warming is limited to well below 2°C, considering global ambitions to achieve a limit of 1.5°C. As one of many shareholders, and typically a minority one, BlackRock does not tell companies what to do. It is the role of the board and management to set and implement a company's long-term strategy to deliver long-term financial returns.

Our research shows that the low-carbon transition is a structural shift in the global economy that will be shaped by changes in government policies, technology, and consumer preferences, which may be material for many companies. 5 Yet the path to a low-carbon economy is deeply uncertain and uneven, with different parts of the economy moving at different speeds. BIS recognizes that it can be challenging for companies to predict the impact of climate-related risk and opportunity on their businesses and operating environments. Many companies are assessing how to navigate the low-carbon transition while delivering long-term value to investors. In this context, we encourage companies to publicly disclose, consistent with their business model and sector, how they intend to deliver long-term financial performance through the transition to a low-carbon economy. Where available, we appreciate companies publishing their transition plan.6

Consistent with the ISSB standards, we are better able to assess preparedness for the low-carbon transition when companies disclose short-, medium- and long-term targets, ideally science-based where these are available for their sector, for scope 1 and 2 greenhouse gas emissions (GHG) reductions and to demonstrate how their targets are consistent with the long-term financial interests of their investors.

While we recognize that regulators in some markets are moving to mandate certain disclosures, at this stage, we view scope 3 emissions differently from scopes 1 and 2, given methodological complexity, regulatory uncertainty, concerns about double-counting, and lack of direct control by companies. We welcome disclosures and commitments companies choose to make regarding scope 3 emissions and recognize these are provided on a good-faith basis as methodology develops. Our publicly available commentary provides more information on our approach to climate-related risks and opportunities.

In addition to climate-related risks and opportunities, the management of nature-related factors is increasingly a component of some companies’ ability to generate durable, long-term financial returns for shareholders, particularly where a company’s strategy is heavily reliant on the availability of natural capital, or whose supply chains are exposed to locations with nature-related risks. We look for such companies to disclose how they manage any reliance and impact on, as well as use of, natural capital, including appropriate risk oversight and relevant metrics and targets, to understand how these factors are integrated into strategy. We will evaluate these disclosures to inform our view of how a company is managing material nature-related risks and opportunities, as well as in our assessment of relevant shareholder proposals. Our publicly available commentary provides more information on our approach to natural capital. 7

Key stakeholder interests

In order to advance long-term shareholders’ interests, companies should consider the interests of the various parties on whom they depend for their success over time. It is for each company to determine their key stakeholders based on what is material to their business and long-term financial performance. For many companies, key stakeholders include employees, business partners (such as suppliers and distributors), clients and consumers, regulators, and the communities in which they operate.

As a long-term shareholder on behalf of our clients, we find it helpful when companies disclose how they have identified their key stakeholders and considered their interests in business decision-making. In addition to understanding broader stakeholder relationships, BIS finds it helpful when companies consider the needs of their workforce today, and the skills required for their future business strategy. We are also interested to understand the role of the board, which is well positioned to ensure that the approach taken is informed by and aligns with the company’s strategy and purpose.

Companies should articulate how they address material adverse impacts that could arise from their business practices and affect critical relationships with their stakeholders. We encourage companies to implement, to the extent appropriate,

5 BlackRock Investment Institute, “Tracking the low-carbon transition”, July 2023.

6 We have observed that more companies are developing such plans, and public policy makers in a number of markets are signaling their intentions to require them. We view transition plans (TPs) as a method for a company to both internally assess and externally communicate long-term strategy, ambition, objectives, and actions to create financial value through the global transition towards a low-carbon economy. While many initiatives across jurisdictions outline a framework for TPs, there is no consensus on the key elements these plans should contain. We view useful disclosure as that which communicates a company’s approach to managing financially material, business relevant risks and opportunities – including climate-related risks – to deliver long-term financial performance, thus enabling investors to make more informed decisions.

Given the growing awareness of the materiality of these issues for certain businesses, enhanced reporting on a company's natural capital dependencies and impacts would aid investors’ understanding. In our view, the final recommendations of the Taskforce on Nature-related Financial Disclosures may prove useful to some companies. We recognize that some companies may report using different standards, which may be required by regulation, or one of a number of other private sector standards.

A-10

monitoring processes (often referred to as due diligence) to identify and mitigate potential adverse impacts and grievance mechanisms to remediate any actual adverse material impacts. In our view, maintaining trust within these relationships can contribute to a company’s long-term success.

Other corporate governance matters and shareholder protections

In our view, shareholders have a right to material and timely information on the financial performance and viability of the companies in which they invest. In addition, companies should publish information on the governance structures in place and the rights of shareholders to influence these structures. The reporting and disclosure provided by companies help shareholders assess the effectiveness of the board’s oversight of management and whether investors’ economic interests have been protected. We believe shareholders should have the right to vote on key corporate governance matters, including changes to governance mechanisms, to submit proposals to the shareholders’ meeting, and to call special meetings of shareholders.

Corporate form

In our view, it is the responsibility of the board to determine the corporate form that is most appropriate given the company's purpose and business model. 8 Companies proposing to change their corporate form to a public benefit corporation or similar entity should put it to a shareholder vote if not already required to do so under applicable law. Supporting documentation from companies or shareholder proponents proposing to alter the corporate form should clearly articulate how the interests of shareholders and different stakeholders would be impacted as well as the accountability and voting mechanisms that would be available to shareholders. As a fiduciary on behalf of clients, we generally support management proposals if our analysis indicates that shareholders’ economic interests are adequately protected. Relevant shareholder proposals are evaluated on a case-by-case basis.

Shareholder proposals

In most markets in which BlackRock invests on behalf of clients, shareholders have the right to submit proposals to be voted on by shareholders at a company’s annual or extraordinary meeting, as long as eligibility and procedural requirements are met. The matters that we see put forward by shareholders address a wide range of topics, including governance reforms, capital management, and improvements in the management or disclosure of sustainability-related risks.

BlackRock is subject to legal and regulatory requirements in the U.S. that place restrictions and limitations on how BlackRock can interact with the companies in which we invest on behalf of our clients, including our ability to submit shareholder proposals. We can vote, on behalf of clients who authorize us to do so, on proposals put forth by others.

When assessing shareholder proposals, we evaluate each proposal on its merit, with a singular focus on its implications for long-term financial value creation by that company. We believe it is helpful for companies to disclose the names of the proponent or organization that has submitted or advised on the proposal. We consider the business and economic relevance of the issue raised, as well as its materiality and the urgency with which our experience indicates it should be addressed. We would not support proposals that we believe would result in over-reaching into the basic business decisions of the company. We take into consideration the legal effect of the proposal, as shareholder proposals may be advisory or legally binding depending on the jurisdiction, while others may make requests that would be deemed illegal in a given jurisdiction.

Where a proposal is focused on a material business risk that we agree needs to be addressed and the intended outcome is consistent with long-term financial value creation, we will look to the board and management to demonstrate that the company has met the intent of the request made in the shareholder proposal. Where our analysis and/or engagement indicate an opportunity for improvement in the company’s approach to the issue, we may support shareholder proposals that are reasonable and not unduly prescriptive or constraining on management.

We recognize that some shareholder proposals bundle topics and/or specific requests and include supporting statements that explain the reasoning or objectives of the proponent. In voting on behalf of clients, we do not submit or edit proposals or the supporting statements – we must vote yes or no on the proposal as phrased by the proponent. Therefore, when we vote in support of a proposal, we are not necessarily endorsing every element of the proposal or the reasoning, objectives, or supporting statement of the proponent. We may support a proposal for different reasons from those put forth by the proponent, when we believe that, overall, it can advance our clients' long-term financial interests. We would normally explain to the company our rationale for supporting such proposals.

8 Corporate form refers to the legal structure by which a business is organized.

A-11

Alternatively, or in addition, we may vote against the election of one or more directors if, in our assessment, the board has not responded sufficiently or with an appropriate sense of urgency. We may also support a proposal if management is on track, but we believe that voting in favor might accelerate efforts to address a material risk.

BlackRock’s oversight of its investment stewardship activities

Oversight

BlackRock maintains three regional advisory committees (Stewardship Advisory Committees) for a) the Americas; b) Europe, the Middle East and Africa; and c) Asia-Pacific, generally consisting of senior BlackRock investment professionals and/or senior employees with practical boardroom experience. The regional Stewardship Advisory Committees review and advise on amendments to BIS regional proxy voting guidelines (the Guidelines) covering markets within each respective region. The advisory committees do not determine voting decisions, which are the responsibility of BIS.

In addition to the regional Stewardship Advisory Committees, the Investment Stewardship Global Oversight Committee (Global Oversight Committee) is a risk-focused committee, comprised of senior representatives from various BlackRock investment teams, a senior legal representative, the Global Head of Investment Stewardship (Global Head), and other senior executives with relevant experience and team oversight. The Global Committee does not determine voting decisions, which are the responsibility of BIS.

The Global Head has primary oversight of the activities of BIS, including voting in accordance with the Guidelines, which require the application of professional judgment and consideration of each company’s unique circumstances. The Global Committee reviews and approves amendments to these Principles. The Global Committee also reviews and approves amendments to the regional Guidelines, as proposed by the regional Stewardship Advisory Committees.

In addition, the Global Committee receives and reviews periodic reports regarding the votes cast by BIS, as well as updates on material process issues, procedural changes, and other risk oversight considerations. The Global Committee reviews these reports in an oversight capacity as informed by the Guidelines.

BIS carries out engagement with companies, executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the relevant Guidelines. BIS also conducts research on corporate governance issues and participates in industry discussions to contribute to and keep abreast of important developments in the corporate governance field. BIS may utilize third parties for certain of the foregoing activities and performs oversight of those third parties. BIS may raise complicated or particularly controversial matters for internal discussion with the relevant investment teams and governance specialists for discussion and guidance prior to making a voting decision.

Vote execution

BlackRock votes on proxy issues when our clients authorize us to do so. When BlackRock has been authorized to vote on behalf of our clients, we carefully consider proxies submitted to funds and other fiduciary account(s) (Fund or Funds) for which we have voting authority. BlackRock votes (or refrains from voting) proxies for each Fund for which we have voting authority based on our evaluation of the alignment of the voting items with the long-term economic interests of our clients, in the exercise of our independent business judgment, and without regard to the relationship of the issuer of the proxy (or any shareholder proponent or dissident shareholder) to the Fund, the Fund’s affiliates (if any), BlackRock or BlackRock’s affiliates, or BlackRock employees (see “Conflicts management policies and procedures,” below).

When exercising voting rights, BIS will normally vote on specific proxy issues in accordance with the Guidelines for the relevant market, as well as the Global Principles. The Guidelines are reviewed annually and are amended consistent with changes in the local market practice, as developments in corporate governance occur, or as otherwise deemed advisable by the applicable Stewardship Advisory Committees. BIS analysts may, in the exercise of their professional judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is required or that an exception to the Guidelines would be in the long-term economic interests of BlackRock’s clients.

In the uncommon circumstance of there being a vote with respect to fixed income securities or the securities of privately held issuers, the decision generally will be made by a Fund's portfolio managers and/or BIS based on an assessment of the particular transactions or other matters at issue.

In certain markets, proxy voting involves logistical issues which can affect BIS’ ability to vote such proxies, as well as the desirability of voting such proxies. These issues include, but are not limited to: i) untimely notice of shareholder meetings; ii) restrictions on a foreigner’s ability to exercise votes; iii) requirements to vote proxies in person; iv) “share-blocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); v) potential difficulties in translating the proxy; vi) regulatory

A-12

constraints; and vii) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as share-blocking or overly burdensome administrative requirements.

As a consequence, BlackRock votes proxies in these situations on a “best-efforts” basis. In addition, BIS may determine that it is generally in the interests of BlackRock’s clients not to vote proxies (or not to vote our full allocation) if the costs (including but not limited to opportunity costs associated with share-blocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the proposal.

Active portfolio managers have full discretion to vote the shares in the Funds they manage based on their analysis of the economic impact of a particular ballot item on their investors. Portfolio managers may, from time to time, reach differing views on how to maximize economic value with respect to a particular investment. Therefore, portfolio managers may, and sometimes do, vote shares in the Funds under their management differently from BIS or from one another. However, because BlackRock’s clients are mostly long-term investors with long-term economic goals, ballots are generally cast in a uniform manner.

Voting Choice

BlackRock offers a Voting Choice program, which provides eligible clients with more opportunities to participate in the proxy voting process where legally and operationally viable. BlackRock Voting Choice aims to make proxy voting easier and more accessible for eligible clients.

Voting Choice is currently available for eligible clients invested in certain institutional pooled funds in the U.S., UK, Ireland, and Canada that utilize equity index investment strategies, as well as eligible clients in certain institutional pooled funds in the U.S., UK, and Canada that use systematic active equity (SAE) strategies. Currently, this includes over 650 pooled investment funds, including equity index funds and SAE investment funds. In addition, institutional clients in separately managed accounts (SMAs) continue to be eligible for BlackRock Voting Choice regardless of their investment strategies. 9

As a result, the shares attributed to BlackRock in company share registers may be voted differently depending on whether our clients have authorized BIS to vote on their behalf, have authorized BIS to vote in accordance with a third-party policy, or have elected to vote shares in accordance with their own policy. Agreements with our clients to allow them greater control over their voting, including which policies they have selected, will be treated confidentially consistent with our treatment of similar client agreements.

Conflicts management policies and procedures

BIS maintains policies and procedures that seek to prevent undue influence on BlackRock’s proxy voting activity. Such influence might stem from any relationship between the investee company (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock’s affiliates, a Fund or a Fund’s affiliates, or BlackRock employees. The following are examples of sources of perceived or potential conflicts of interest:

•

BlackRock clients who may be issuers of securities or proponents of shareholder resolutions

•

BlackRock business partners or third parties who may be issuers of securities or proponents of shareholder resolutions

•

BlackRock employees who may sit on the boards of public companies held in Funds managed by BlackRock

•

Significant BlackRock, Inc. investors who may be issuers of securities held in Funds managed by BlackRock

•

Securities of BlackRock, Inc. or BlackRock investment funds held in Funds managed by BlackRock

•

BlackRock, Inc. board members who serve as senior executives or directors of public companies held in Funds managed by BlackRock

BlackRock has taken certain steps to mitigate perceived or potential conflicts including, but not limited to, the following:

•

Adopted the Guidelines which are designed to advance our clients’ long-term economic interests in the companies in which BlackRock invests on their behalf

•

Established a reporting structure that separates BIS from employees with sales, vendor management, or business partnership roles. In addition, BlackRock seeks to ensure that all engagements with corporate issuers, dissident shareholders or shareholder proponents are managed consistently and without regard to BlackRock’s relationship with such parties. Clients or business partners are not given special treatment or differentiated access to BIS. BIS

Within the normal course of business, BIS may engage directly with BlackRock clients, business partners and/or third parties, and/or with employees with sales, vendor management, or business partnership roles, in discussions regarding our approach to stewardship, general corporate governance matters, client reporting needs, and/or to otherwise ensure that proxy-related client service levels are met

In such circumstances, the independent third-party voting service provider provides BlackRock with recommendations, in accordance with the Guidelines, as to how to vote such proxies. BlackRock uses an independent third-party voting service provider to make proxy voting recommendations for shares of BlackRock, Inc. and companies affiliated with BlackRock, Inc. BlackRock may also use an independent third-party voting service provider to make proxy voting recommendations for:

public companies when legal or regulatory requirements compel BlackRock to use an independent third-party voting service provider

In selecting an independent third-party voting service provider, we assess several characteristics, including but not limited to: independence, an ability to analyze proxy issues and make recommendations in the economic interest of our clients in accordance with the Guidelines, reputation for reliability and integrity, and operational capacity to accurately deliver the assigned recommendations in a timely manner. We may engage more than one independent third-party voting service provider, in part to mitigate potential or perceived conflicts of interest at a single voting service provider. The Global Committee appoints and reviews the performance of the independent third-party voting service providers, generally on an annual basis.

Securities lending

When so authorized, BlackRock acts as a securities lending agent on behalf of Funds. Securities lending is a well-regulated practice that contributes to capital market efficiency. It also enables funds to generate additional returns while allowing fund providers to keep fund expenses lower.

With regard to the relationship between securities lending and proxy voting, BlackRock cannot vote shares on loan and may determine to recall them for voting, as guided by our fiduciary responsibility to act in our clients’ financial interests. While this has occurred in a limited number of cases, the decision to recall securities on loan as part of BlackRock’s securities lending program in order to vote is based on an evaluation of various factors that include, but are not limited to, assessing potential securities lending revenue alongside the potential long-term financial value to clients of voting those securities (based on the information available at the time of recall consideration). 10 BIS works with colleagues in the Securities Lending and Risk and Quantitative Analysis teams to evaluate the costs and benefits to clients of recalling shares on loan.

In almost all instances, BlackRock anticipates that the potential long-term financial value to the Fund of voting shares would be less than the potential revenue the loan may provide the Fund. However, in certain instances, BlackRock may determine, in our independent business judgment as a fiduciary, that the value of voting outweighs the securities lending revenue loss to clients and would therefore recall shares to be voted in those instances.

Periodically, BlackRock reviews our process for determining whether to recall securities on loan in order to vote and may modify it as necessary.

Recalling securities on loan can be impacted by the timing of record dates. In the U.S., for example, the record date of a shareholder meeting typically falls before the proxy statements are released. Accordingly, it is not practicable to evaluate a proxy statement, determine that a vote has a material impact on a fund and recall any shares on loan in advance of the record date for the annual meeting. As a result, managers must weigh independent business judgement as a fiduciary, the benefit to a fund’s shareholders of recalling loaned shares in advance of an estimated record date without knowing whether there will be a vote on matters which have a material impact on the fund (thereby forgoing potential securities lending revenue for the fund’s shareholders) or leaving shares on loan to potentially earn revenue for the fund (thereby forgoing the opportunity to vote).

Voting guidelines

The voting guidelines published for each region/country in which we vote are intended to summarize BlackRock’s general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. The Guidelines are not intended to be exhaustive. BIS applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review. As such, the Guidelines do not indicate how BIS will vote in every instance. Rather, they reflect our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots. As previously discussed, the Guidelines should be read in conjunction with the Principles and engagement priorities. Collectively, these “BIS policies” set out the core elements of corporate governance that guide our investment stewardship efforts globally and within each market, including when engaging with companies and voting at shareholder meetings. The BIS policies are applied on a case-by-case basis, taking into consideration the context within which a company is operating.

Reporting and vote transparency

We are committed to transparency in the stewardship work we do on behalf of clients. We inform clients about our engagement and voting policies and activities through direct communication and through disclosure on our website. Each year we publish an annual report that provides a global overview of our investment stewardship engagement and voting activities and a voting spotlight that summarizes our voting over a proxy year.11 Additionally, we make public our regional proxy voting guidelines for the benefit of clients and the companies in which we invest on their behalf. We also publish commentaries to share our perspective on market developments and emerging key themes.

At a more granular level, on a quarterly basis, we publish our vote record for each company that held a shareholder meeting during the period, showing how BIS voted on each proposal and providing our rationale for any votes against management proposals or on shareholder proposals. For shareholder meetings where a vote might be high profile or of significant interest to clients, we may publish a vote bulletin after the meeting, disclosing and explaining our vote on key proposals. We also publish a quarterly list of all companies with which we engaged and the key topics addressed in the engagement meeting.

In this way, we help inform our clients about the work we do on their behalf in promoting the governance and business practices that support durable, long-term financial value creation.

The proxy year runs from July 1 to June 30.

Appendix B – Description of Fixed-Income Ratings

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a NRSRO by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

NRSROs may rate specific investments (e.g., bonds), issuers (e.g., corporations, governments and financial institutions) and/or programs (e.g., commercial paper programs). However, certain types of investments may not be rated by NRSROs, such as certain government/sovereign obligations, US agency securities, commercial paper, time deposits at financial institutions, and derivative instruments such as credit default swaps. For these types of investments, as well as US Treasury securities (some of which are not rated), where a NRSRO has not rated the specific investment but has rated the investment’s issuer, program, financial institution or underlying reference asset, BFA may consider the investment to have the same NRSRO rating as its issuer, program, financial institution or underlying reference asset, as applicable. In the case of municipal securities, where one NRSRO provides multiple ratings for the same security (e.g., “underlying,” “insured” and/or “enhanced” ratings), BFA may consider the security to have the highest of the multiple ratings.

New issue securities (regardless of type) may not be rated by a NRSRO at the time of their initial offering. Preliminary prospectuses or term sheets for new issue securities may include an expected rating for the security (as determined by the underwriter and/or issuer) or a NRSRO rating for the issuer of the security. If applicable, when deciding whether to purchase a new issue security that has not yet been rated by a NRSRO, BFA may attribute an expected rating to the security based on: (i) the expected rating of the security set forth in the preliminary prospectus or term sheet for the security; (ii) the NRSRO’s rating for the issuer of the security set forth in the preliminary prospectus or term sheet for the security; or (iii) with respect to asset-backed securities, the rating of a prior issuance having a similar structure or the same sponsor.

Where the investment objective of a Fund is to track the performance of an index that includes credit ratings eligibility criteria as part of its index methodology, a Fund may purchase any security within the index, such security having been determined by the index provider as meeting its credit ratings eligibility criteria. The credit ratings practices of an index provider may differ from BlackRock’s practices, as described above. Further, a Fund may invest, directly or indirectly, in securities that are not rated by a rating agency or securities with a credit rating that differs from the credit rating specified in its index methodology in various circumstances, including where a security is downgraded but not yet removed from an index, following the removal of a security from an index prior to its sale by the Fund or as a result of a corporate action or restructuring affecting an issuer of a security held by a Fund.

Fixed-income securities which are unrated may expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on the investment adviser’s judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer’s ability to make interest and principal payments or on the likelihood of default.

Securities deemed to be high yield are rated below Baa3 by Moody’s and below BBB- by S&P Global Ratings and Fitch.

The descriptions below relate to general long-term and short-term obligations of an issuer.

Moody’s Ratings

Long-Term Obligations

Aaa: Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

Aa: Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A: Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.

Baa: Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

B-1

Ba: Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high credit risk.

Caa: Obligations rated Caa are judged to be speculative, of poor standing and are subject to very high credit risk.

Ca: Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody's appends numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Absence of Rating: Where no rating has been assigned or where a rating has been withdrawn, it may be for reasons unrelated to the creditworthiness of the issue.

Should no rating be assigned, the reason may be one of the following:

1. An application was not received or accepted.

2. The issue or issuer belongs to a group of securities or entities that are not rated as a matter of policy.

3. There is a lack of essential data pertaining to the issue or issuer.

4. The issue was privately placed, in which case the rating is not published in Moody’s publications.

Withdrawal may occur if new and material circumstances arise, the effects of which preclude satisfactory analysis; if there is no longer available reasonable up-to-date data to permit a judgment to be formed; if a bond is called for redemption; or for other reasons.

Short-Term Obligations

Moody’s short-term debt ratings are opinions of the ability of issuers to honor short-term financial obligations, generally with an original maturity not exceeding thirteen months.

Moody's employs the following designations to indicate the relative repayment ability of rated issuers:

P-1: Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

NP: Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

US Municipal Short-Term Debt Obligations

There are three rating categories for short-term municipal obligations that are considered investment-grade and are designated as Municipal Investment Grade (MIG). In addition, those short-term obligations that are of speculative quality are designated SG, or speculative grade. MIG ratings expire at the maturity of the obligation.

MIG 1: This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2: This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3: This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

B-2

SG: This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

S&P Global Ratings

Long-Term Obligations

AAA: An obligation rated AAA has the highest rating assigned by S&P Global Ratings. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA: An obligation rated AA differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment is very strong.

A: An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB; B; CCC; CC; and C: Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment. The CC rating is used when a default has not yet occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

C: An obligation rated C is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.

D: An obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to D if it is subject to a distressed exchange offer.

NR: NR indicates no rating has been requested, or that there is insufficient information on which to base a rating, or that S&P Global Ratings does not rate a particular obligation as a matter of policy.

Note: The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

Short-Term Obligations

B-3

A-1: A short-term obligation rated A-1 is rated in the highest category by S&P Global Ratings. The obligor's capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

B: A short-term obligation rated B is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties which could lead to the obligor's inadequate capacity to meet its financial commitments.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to D if it is subject to a distressed exchange offer.

Municipal Short-Term Obligations

An S&P U.S. municipal note rating reflects S&P Global Ratings opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating.

SP-1: Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2: Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3: Speculative capacity to pay principal and interest.

Fitch Ratings

Long-Term Obligations

AAA: Highest credit quality. AAA ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very high credit quality. AA ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality. A ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB: Good credit quality. BBB ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.

B-4

BB: Speculative. BB ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.

B: Highly speculative. B ratings indicate that material credit risk is present.

CCC: Substantial credit risk. CCC ratings indicate that substantial credit risk is present.

CC: Very high levels of credit risk. CC ratings indicate very high levels of credit risk.

C: Exceptionally high levels of credit risk. C indicates exceptionally high levels of credit risk.

Defaulted obligations typically are not assigned RD or D ratings, but are instead rated in the B to C rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Note: The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA obligation rating category, or to corporate finance obligation ratings in the categories below CCC.

The subscript 'emr' is appended to a rating to denote embedded market risk which is beyond the scope of the rating. The designation is intended to make clear that the rating solely addresses the counterparty risk of the issuing bank. It is not meant to indicate any limitation in the analysis of the counterparty risk, which in all other respects follows published Fitch criteria for analyzing the issuing financial institution. Fitch does not rate these instruments where the principal is to any degree subject to market risk.

Short-Term Obligations (Corporate and Public Finance)

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity or security stream and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short-term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

F1: Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2: Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.

F3: Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B: Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

C: High short-term default risk. Default is a real possibility.

RD: Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Dominion Bond Rating Service Limited

Long-Term Obligations

AAA: Highest credit quality. The capacity for the payment of financial obligations is exceptionally high and unlikely to be adversely affected by future events.

AA: Superior credit quality. The capacity for the payment of financial obligations is considered high. Credit quality differs from AAA only to a small degree. Unlikely to be significantly vulnerable to future events.

B-5

A: Good credit quality. The capacity for the payment of financial obligations is substantial, but of lesser credit quality than AA. May be vulnerable to future events, but qualifying negative factors are considered manageable.

BBB: Adequate credit quality. The capacity for the payment of financial obligations is considered acceptable. May be vulnerable to future events.

BB: Speculative, non investment-grade credit quality. The capacity for the payment of financial obligations is uncertain. Vulnerable to future events.

B: Highly speculative credit quality. There is a high level of uncertainty as to the capacity to meet financial obligations.

CCC / CC / C: Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.

D: When the issuer has filed under any applicable bankruptcy, insolvency or winding up statute or there is a failure to satisfy an obligation after the exhaustion of grace periods, a downgrade to D may occur.

Note: All rating categories other than AAA and D also contain subcategories “(high)” and “(low)”. The absence of either a “(high)” or “(low)” designation indicates the rating is in the middle of the category.

Commercial Paper and Short-Term Debt

R-1 (high): Highest credit quality. The capacity for the payment of short-term financial obligations as they fall due is exceptionally high. Unlikely to be adversely affected by future events.

R-1 (middle): Superior credit quality. The capacity for the payment of short-term financial obligations as they fall due is very high. Differs from R-1 (high) by a relatively modest degree. Unlikely to be significantly vulnerable to future events.

R-1 (low): Good credit quality. The capacity for the payment of short-term financial obligations as they fall due is substantial. Overall strength is not as favorable as higher rating categories. May be vulnerable to future events, but qualifying negative factors are considered manageable.
R-2 (high): Upper end of adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events.

R-2 (middle): Adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events or may be exposed to other factors that could reduce credit quality.

R-2 (low): Lower end of adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events. A number of challenges are present that could affect the issuer's ability to meet such obligations.

R-3: Lowest end of adequate credit quality. There is a capacity for the payment of short-term financial obligations as they fall due. May be vulnerable to future events and the certainty of meeting such obligations could be impacted by a variety of developments.

R-4: Speculative credit quality. The capacity for the payment of short-term financial obligations as they fall due is uncertain.

R-5: Highly speculative credit quality. There is a high level of uncertainty as to the capacity to meet short-term financial obligations as they fall due.
