iSHARES^® MORNINGSTAR MULTI-ASSET INCOME ETF

Investment Objective

The iShares Morningstar Multi-Asset Income ETF (the “Fund”) seeks to track the investment results of an index composed of underlying equity, fixed income and other income funds that collectively seek to deliver high current income while providing an opportunity for capital appreciation.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fee in order to limit the Fund’s total annual fund operating expenses after the fee waiver to 0.60% through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA.

You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Principal Investment Strategies

The Fund is a fund-of-funds and seeks to achieve its investment objective by investing primarily in the securities of the Underlying Funds that themselves seek investment results corresponding to their own underlying indexes. The Fund invests in a combination of Underlying Funds and may also invest in other exchange-traded funds (“ETFs”) (including other iShares funds), U.S. government securities, short-term paper, futures contracts, options on futures contracts, options, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”).

The Morningstar^® Multi-Asset High Income Index^SM (the “Underlying Index”) is broadly diversified and seeks to deliver high current income while maintaining long-term capital appreciation.  The goal of the Underlying Index is to represent an allocation strategy to distinct asset classes of 20% equities, 60% fixed-income and 20% in an “alternative income sources” asset class, which consists of Underlying Funds that the index provider, Morningstar, Inc. (“Morningstar” or the “Index Provider”), considers to exhibit both equity and fixed-income-like characteristics. Each asset class has its own risk profile. The Underlying Index is rebalanced and reconstituted quarterly. The Underlying Index is comprised of Underlying Funds within these asset classes that have demonstrated relatively high income on a consistent basis and meet liquidity characteristics as determined by Morningstar's proprietary index methodology.

The 20% equity allocation consists of Underlying Funds that invest primarily in U.S. and non-U.S. equities. The 60% fixed-income allocation consists of Underlying Funds that invest primarily in U.S. and non-U.S. fixed-income securities. The 20% alternative income source allocation generally consists of Underlying Funds that invest primarily in real estate investment trusts (“REITs”) and preferred stocks. When the combined allocation percentages equal less than 100%, the Fund may invest the remainder of its assets in BlackRock Cash Funds. Investments in Underlying Funds that have significant non-U.S. currency exposure will not exceed 25% of the weight of the Underlying Index.

As of July 31, 2022, the Underlying Index included the following Underlying Funds within the equity asset class: iShares Emerging Markets Dividend ETF and iShares International Select Dividend 

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1 and 5 years and since inception compare with the Underlying Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. If BFA had not waived certain Fund fees during certain periods, the Fund's returns would have been lower.

Year by Year Returns¹ (Years Ended December 31)

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on Cboe BZX Exchange, Inc. (“Cboe BZX”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents an ownership interest in an underlying portfolio of securities and other instruments intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by Authorized Participants and only in aggregations of a specified number of shares (“Creation Units”). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

An index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from the Fund's or each Underlying Fund's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index. From time to time, the Index Provider may make changes to the methodology or other adjustments to the Underlying Index. Unless otherwise determined by BFA, any such change or adjustment will be reflected in the calculation of the Underlying Index performance on a going-forward basis after the effective date of such change or adjustment. Therefore, the Underlying Index performance shown for periods prior to the effective date of any such change or adjustment will generally not be recalculated or restated to reflect such change or adjustment.

“Tracking error” is the divergence of the Fund's performance from that of the Underlying Index. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. The Fund may be exposed to these risks directly or indirectly through the Fund's investments in the Underlying Funds. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments. The order of the below risk factors does not indicate the significance of any particular risk factor. The Fund discloses its portfolio holdings daily at www.iShares.com.

Affiliated Fund Risk. In managing the Fund, BFA has the ability to select Underlying Funds and substitute other ETFs which it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.

Allocation Risk. The Fund’s ability to achieve its investment objective depends upon the Index Provider’s ability to develop a model that accurately assesses the Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider’s evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions. The Fund’s Underlying Index may overweight certain asset classes relative to market capitalization-weighted benchmarks. The Fund will underperform such benchmarks when asset classes that are overweighted in the Fund’s Underlying Index underperform other asset classes.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s or an Underlying Fund's portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of

1

industries, markets, market segments, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Calculation Methodology Risk. The Underlying Index  relies on various sources of information to assess the criteria of issuers included in the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Underlying Index's calculation methodology or sources of information will provide an accurate assessment of included issuers.

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

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's or an Underlying Fund's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class. The Fund may be more adversely affected by the underperformance of those securities and/or other assets, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities and/or other assets than a fund that does not concentrate its investments.

Credit Risk. Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments when due or otherwise honor its obligations. There are varying degrees of credit risk, depending on an issuer’s or counterparty’s financial condition and on the terms of an obligation, which may be reflected in the issuer’s or counterparty’s credit rating. There is the chance that the Fund’s or an Underlying Fund's portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing such Fund’s or an Underlying Fund's income level or share price, which may adversely affect the value of the Fund.

Currency Risk. Because the Fund's and the Underlying Funds' NAVs are determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency, even if such currency value of the Fund's holdings in that market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades, as well as the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may 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. In general, the less developed a country’s securities markets are, the higher the degree of custody risk.

Cybersecurity Risk. The Fund, the Underlying Funds, Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through their service providers.  Similar types of cybersecurity risks are also present for issuers of securities in which the Fund or the Underlying Funds invest, which could result in material adverse consequences for such issuers and may cause the Fund’s or an Underlying Fund's investment in such issuers to lose value. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Recently, geopolitical tensions may have increased the scale and sophistication of deliberate attacks, particularly those

2

from nation-states or from entities with nation-state backing.

Cybersecurity failures by, or breaches of, the systems of the Fund's or an Underlying Fund's adviser, distributor and other service providers (including, but not limited to, index and benchmark providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund or the Underlying Funds invest have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s or an Underlying Fund's ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund, each Underlying Fund or their service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyberattacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund or an Underlying Fund inaccessible, inaccurate or incomplete. Substantial costs may be incurred by the Fund or an Underlying Fund in order to resolve or prevent cyber incidents in the future. While the Fund and the Underlying Funds have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that prevention and remediation efforts will not be successful or that cyberattacks will go undetected. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Dividend-Paying Stock Risk. Investing in dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the broader market. Companies that issue dividend-paying stocks are not required to pay or continue paying dividends on such stocks. It is possible that issuers of the stocks held by the Fund or an Underlying Fund will not declare dividends in the future or will reduce or eliminate the payment of dividends (including reducing or eliminating anticipated accelerations or increases in the payment of dividends) in the future.

Equity Securities Risk. Certain Underlying Funds invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index is composed of common stocks, which generally subject their holders to more risks than preferred stocks and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Companies in the financials sector of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund or an Underlying Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Increased risk taking by banks may also result in greater overall risk in the U.S. and global financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted.

Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. 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. 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 may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financials sector generally. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyberattacks, and may experience technology malfunctions and disruptions. Cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact an Underlying Fund.

Geographic Risk. Some of the companies in which the Fund or an Underlying Fund invests are located in parts of the world that have historically been prone to natural disasters such as earthquakes, tornadoes, volcanic eruptions, droughts, floods, hurricanes or tsunamis and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of the Fund.

High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” which may include those bonds rated below “BBB-” by S&P Global Ratings and Fitch, or below “Baa3” by Moody’s), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.

3

The major risks of high yield securities investments include:

■	High yield securities may be issued by less creditworthy issuers. Issuers of high yield securities may have a larger amount of outstanding debt relative to their assets than issuers of investment-grade bonds. In the event of an issuer’s bankruptcy, claims of other creditors may have priority over the claims of high yield securities holders, leaving few or no assets available to repay high yield securities holders.
■	Prices of high yield securities are subject to extreme price fluctuations. Adverse changes in an issuer’s industry and general economic conditions may have a greater impact on the prices of high yield securities than on other higher rated fixed-income securities. The credit rating of a high yield security does not necessarily address its market value risk. Ratings and market value may change from time to time, positively or negatively, to reflect new developments regarding the issuer.
■	Issuers of high yield securities may be unable to meet their interest or principal payment obligations because of an economic downturn, specific issuer developments, or the unavailability of additional financing.
■	High yield securities frequently have redemption features that permit an issuer to repurchase the security from the Fund or an Underlying Fund before it matures. If the issuer redeems high yield securities held by the Fund or an Underlying Fund, the Fund or an Underlying Fund may have to invest the proceeds in bonds with lower yields and may lose income.
■	High yield securities may be less liquid than higher rated fixed-income securities, even under normal economic conditions. There are fewer dealers in the high yield securities market, and there may be significant differences in the prices quoted for high yield securities by the dealers. Because high yield securities may be less liquid than higher rated fixed-income securities, judgment may play a greater role in valuing certain of  an Underlying Fund's securities than is the case with securities trading in a more liquid market.
■	An Underlying Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer.

Income Risk. The Fund’s income may decline if interest rates fall.  This decline in income can occur because the Fund or an Underlying Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called; or the Fund or an Underlying Fund otherwise needs to purchase additional bonds. 

Index-Related Risk. The Fund seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider or any agents that may act on its behalf will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. In addition, there may be heightened risks associated with the adequacy and reliability of the information the Index Provider uses given the Fund's exposure to emerging markets, as certain emerging markets may have less information available or less regulatory oversight. Such errors may negatively or positively impact the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Shareholders should understand that any gains from Index Provider errors will be kept by the Fund and its shareholders and any losses or costs resulting from Index Provider errors will be borne by the Fund and its shareholders.

Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider, and could cause the Index Provider to postpone a scheduled rebalance to the Underlying Index. This could cause the Underlying Index to vary from its normal or expected composition. The postponement of a scheduled rebalance could mean that constituents of the Underlying Index that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Underlying Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Index due to reaching certain weighting constraints, unusual market conditions or corporate events or, for example, to correct an error in the selection of index constituents. When the Underlying Index is rebalanced and the Fund in turn rebalances its portfolio to attempt to increase the correlation between the Fund’s portfolio and the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Similar risks exist for the Underlying Funds in tracking their benchmarks, which may result in the Fund's performance deviating from the return of the Underlying Index.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may adversely affect the economies of many nations and the global economy and may impact individual issuers and capital markets in ways that cannot be foreseen.

4

An infectious illness outbreak may result in travel restrictions, closed international borders, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, temporary and permanent closures of businesses, layoffs, defaults and other significant economic, social and political impacts, as well as general concern and uncertainty.

An infectious illness outbreak may result in extreme volatility, severe losses, credit deterioration of issuers, and disruptions in markets, which could adversely impact the Fund and its investments, including impairing any hedging activity.

Certain local markets may be subject to closures. Any suspension of trading in markets in which the Fund or an Underlying Fund invests will have an impact on the Fund or an Underlying Fund and its investments and will impact the Fund’s ability to purchase or sell securities in such markets. Market or economic disruptions could result in elevated tracking error and increased premiums or discounts to the Fund's NAV. Additionally, an outbreak could impair the operations of the Fund’s service providers, including BFA, which could adversely impact the Fund.

Governmental and quasi-governmental authorities and regulators throughout the world may respond to an outbreak and any resulting economic disruptions with a variety of fiscal and monetary policy changes, including direct capital infusions into companies and other issuers, new monetary policy tools, and changes in interest rates. A reversal of these policies, or the ineffectiveness of such policies, is likely to increase market volatility, which could adversely affect the Fund’s or an Underlying Fund's investments.

An outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally, which could adversely affect the Fund and its investments and could result in increased premiums or discounts to the Fund's NAV.

Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Interest Rate Risk. If interest rates rise, the value of fixed-income securities or other instruments held by the Fund or an Underlying Fund would likely decrease. A measure investors commonly use to determine this price sensitivity is called duration. Fixed-income securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. For example, if a bond has a duration of five years and interest rates rise, the price of the bond will likely decline by a greater percentage than if the bond had a one year duration. To the extent the Fund or an Underlying Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Fund's or an Underlying Fund's investments to decline significantly, which would adversely affect the value of the Fund. An increase in interest rates may lead to heightened volatility in the fixed-income markets and adversely affect certain fixed-income investments, including those held by the Fund or an Underlying Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Underlying Fund to the extent that it invests in floating rate debt securities. In addition, decreases in fixed income dealer market-making capacity may lead to lower trading volume, heightened volatility, wider bid-ask spreads and less transparent pricing in certain fixed-income markets.

The historically low interest rate environment in recent years was created in part by the world’s major central banks keeping their overnight policy interest rates at, near or below zero percent and implementing monetary policy facilities, such as asset purchase programs, to anchor longer-term interest rates below historical levels. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Certain countries have recently experienced negative interest rates on certain fixed-income instruments. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are set at low levels and the market prices of portfolio securities have increased, the Fund or an Underlying Fund may have a very low or even negative yield. A low or negative yield would cause the Fund or an Underlying Fund to lose money in certain conditions and over certain time periods. Central banks may increase their short-term policy rates or begin phasing out, or “tapering,” accommodative monetary policy facilities in the future. The timing, coordination, magnitude and effect of such policy changes on various markets are uncertain, and such changes in monetary policy may adversely affect the value of the Fund’s investments.

Investment in Underlying Funds Risk. The Fund expects to invest substantially all of its assets in the Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund may also invest in other funds, including money market funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Funds. For example, in addition to the expenses of the Fund, the Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Funds, although some of such fees will be offset by the fee waiver by BFA.

One Underlying Fund may buy the same securities that another Underlying Fund sells. Also, an investor in the Fund may receive taxable gains from portfolio transactions by the Underlying Funds, as well as taxable gains from transactions in shares of the Underlying Funds held by the Fund. Certain of the funds may also hold common portfolio securities.

5

As the Underlying Funds, or the Fund's allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of the Underlying Funds change, the weighted average operating expenses borne by the Fund may increase or decrease.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or the Underlying Funds have exposure. The Fund may be adversely affected if an issuer of underlying securities held by the Fund is unable or unwilling to repay principal or interest when due. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations. 

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. Because BFA uses a representative sampling indexing strategy, the Fund will not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund and the Underlying Funds could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers,  exchange or exchanges, country, group of countries, region, market, industry, group of industries, sector or asset class. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund, the Underlying Funds and their investments and could result in increased premiums or discounts to the Fund’s or Underlying Fund's NAV. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, may exacerbate social unrest, violence and labor unrest in some of the countries in which the Fund may invest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some countries in which the Fund may invest may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions, which would have a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation Risk. Investments in certain countries in which the Fund may invest may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund may invest may adversely impact securities held by the Fund.

Market Trading Risk.

Absence of Active Market. Although shares of the Fund and the Underlying Funds are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants.

Risk of Secondary Listings. The Fund's and each Underlying Fund's shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund's or each Underlying Fund's primary listing is maintained, and may otherwise be made available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts. There can be no assurance

6

that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund's or each Underlying Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund or the Underlying Funds may trade in the secondary market at times when the Fund or the Underlying Funds do not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund or the Underlying Funds accept purchase and redemption orders. If the Fund purchases shares of an Underlying Fund at a time when the market price of Underlying Fund shares is at a premium to their NAV or sells Underlying Fund shares when their market price is at a discount to their NAV, the Fund may incur losses.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Shares of the Fund or an Underlying Fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short. In addition, trading activity in derivative products based on the Fund or an Underlying Fund may lead to increased trading volume and volatility in the secondary market for the shares of the Fund or an Underlying Fund.

Shares of the Fund and the Underlying Funds May Trade at Prices Other Than NAV. Shares of the Fund and an Underlying Fund each trade on stock exchanges at prices at, above or below the Fund’s and the Underlying Fund's most recent respective NAV. The NAV of the Fund and each Underlying Fund are calculated at the end of each business day and fluctuate with changes in the market value of the Fund’s or an Underlying Fund's holdings. The trading price of each of the Fund's and Underlying Funds' shares fluctuates continuously throughout trading hours based on both market supply of and demand for their shares and the underlying value of their portfolio holdings or NAV. As a result, the trading prices of the Fund’s and each Underlying Fund's shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S OR THE UNDERLYING FUNDS' SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund or the Underlying Funds, as applicable, are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s or an Underlying Fund's shares normally will trade on stock exchanges at prices close to the Fund’s or an Underlying Fund's next calculated NAV, exchange prices are not expected to correlate exactly with their respective NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund or an Underlying Fund that differ significantly from their respective NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s or the Underlying Fund's shares trading at a premium or discount to NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission and other charges. In addition, you may incur the cost of the “spread”; that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time for shares of the Fund based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and therefore the share price of an Underlying Fund that invests mostly in mid-capitalization companies may increase or decrease by a greater percentage than those of funds that invest solely in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than large-capitalization stocks to adverse business or economic developments and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund or an Underlying Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

7

Model Risk. Neither the Fund nor BFA can offer any assurance that the allocation model used to calculate the Underlying Index will achieve its intended results or maximize returns or minimize risks, nor can the Fund or BFA offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers have different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, uncertainties of transnational litigation, and potential restrictions on the flow of international capital, including the possible seizure or nationalization of the securities issued by non-U.S. issuers held by the Fund or an Underlying Fund. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. Unfavorable political, economic or governmental developments in non-U.S. countries could affect the payment of a security’s principal and interest. Securities issued by non-U.S. issuers may also be less liquid than, and more difficult to value than, securities of U.S. issuers. In addition, the value of these securities may fluctuate due to changes in the exchange rate of the issuer’s local currency against the U.S. dollar.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks of investing in the markets where such issuers are located, including heightened risks of inflation, nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Underlying Funds that invests in foreign securities may be subject to increased risk of loss caused by any of the factors listed below:

■	Government intervention in issuers' operations or structure;
■	A lack of market liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of an Underlying Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements and the risk of being delisted from U.S. exchanges; and
■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Underlying Funds may invest may differ from or may not be as extensive or protective as those that apply in the U.S.

Withholding Tax Reclaims Risk. The Fund or the Underlying Fund may file claims to recover withholding tax on dividend and interest income (if any) received from issuers in certain countries where such withholding tax reclaim is possible. Whether or when the Fund or the Underlying Fund will receive a withholding tax refund in the future is within the control of the tax authorities in such countries. Where the Fund or the Underlying Fund expects to recover withholding tax based on a continuous assessment of probability of recovery, the NAV of the Fund or the Underlying Fund generally includes accruals for such tax refunds. The Fund and the Underlying Fund continue to evaluate tax developments for potential impact to the probability of recovery. If the likelihood of receiving refunds materially decreases, for example due to a change in tax regulation or approach, accruals in the Fund’s or the Underlying Fund's NAV for such refunds may need to be written down partially or in full, which will adversely affect that Fund’s or the Underlying Fund's NAV. Investors in the Fund or the Underlying Fund at the time an accrual is written down will bear the impact of any resulting reduction in NAV regardless of whether they were investors during the accrual period.  Conversely, if a Fund or the Underlying Fund receives a tax refund that has not been previously accrued, investors in the Fund or the Underlying Fund at the time the claim is successful will benefit from any resulting increase in the Fund’s NAV. Investors who sold their shares prior to such time will not benefit from such NAV or the Underlying Fund's increase.

Operational Risk. The Fund and the Underlying Funds are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund's or an Underlying Fund's service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Funds and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund and the Underlying Funds are not actively managed and may be affected by a general decline in market segments related to the Underlying Indexes. The Fund and the Underlying Funds invest in securities included in, or representative of, the

8

applicable underlying index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Privately Issued Securities Risk. The Fund or the Underlying Funds may invest in privately issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S under the 1933 Act. Privately issued securities typically may be resold only to qualified institutional buyers, or in a privately negotiated transaction, or to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund and an Underlying Fund may find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held and traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s NAV due to the absence of an active trading market. There can be no assurance that a privately issued security that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund and an Underlying Fund, and its value may decline as a result.

Privatization Risk. Some countries in which the Underlying Funds have exposure have privatized, or have 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.

Reinvestment Risk. A Fund or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and as a result, may be adversely affected when interest rates fall because they may have to invest in lower yielding bonds as bonds mature. This may cause the Fund's or an Underlying Fund's income to decline, which may adversely affect the value of the Fund. This risk is typically greater with respect to short-term bond funds and lower for long-term bond funds.

Reliance on Trading Partners Risk. The economies of many countries or regions in which certain of the Underlying Funds invest are highly dependent on trading with certain key trading partners. Reduction in spending on products and services by these key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of key trading partners may adversely affect the performance of any company in which such Underlying Funds invest and may have a material adverse effect on the Underlying Funds' performance.

Risk of Investing in Emerging Markets. Investments in emerging market issuers are subject to a greater risk of loss than investments in issuers located or operating in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Fund invests may be less reliable or complete. Moreover, emerging markets often have less reliable securities valuations and greater risks associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. The Fund is not actively managed and does not select investments based on investor protection considerations.

In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to changes in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. (and other developed countries). In addition, significant delays may occur in certain markets in registering the transfer of securities. Settlement or registration problems may make it more difficult for the Fund or an Underlying Fund to value its portfolio securities and could cause the Fund to miss attractive investment opportunities. 

Investing in emerging market countries involves a higher 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 in certain emerging market countries.

Investing in emerging market countries involves a great 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 in certain emerging market countries.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Risk of Investing in Emerging Markets” and “Non-U.S. Securities Risk,” that are not typically associated with investing in U.S. securities, including:

■	The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
■	Risks in connection with the maintenance of the Fund's or an Underlying Fund’s portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund or an Underlying Fund;
■	The risk that the Fund's or an Underlying Fund’s ownership rights in portfolio securities could be lost through fraud or negligence because ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system;
■	The risk that the Fund or an Underlying Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the Russian government; and
■	The risk that various responses by other nation-states to alleged Russian cyber activity will impact Russia’s economy and Russian issuers of securities in which the Fund invests.

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 and Russian issuers of securities in which the Fund  or the Underlying Funds invest. 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 globally. 

Russia Sanctions. Governments in the U.S. and many other countries (collectively, the “Sanctioning Bodies”) have imposed economic sanctions on certain Russian individuals, including politicians, and Russian corporate and banking entities, including banning Russia from global payments systems that facilitate cross-border payments. The Sanctioning Bodies, or others, could also institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of the Fund or Underlying Fund to buy, sell, receive or deliver those securities and/or assets.

The sanctions against certain Russian issuers include prohibitions on transacting in or dealing in issuances of debt or equity of such issuers. Compliance with each of these sanctions has and may continue to impair the ability of the Fund or an Underlying Fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. If it becomes impracticable or unlawful for the Fund or an Underlying Fund to hold securities subject to, or otherwise affected by, sanctions (collectively, “affected securities”), or if deemed appropriate by BFA, the Fund or an Underlying Fund may prohibit in-kind deposits of the affected securities in connection with creation transactions and instead require a cash deposit, which may also increase an Underlying Fund's transaction costs. An Underlying Fund may also be legally required to freeze assets in a blocked account.

Sanctions have resulted in Russia taking counter measures or retaliatory actions, which has impaired the value and liquidity of Russian securities.  These retaliatory measures include the immediate freeze of Russian assets held by the Fund's or an Underlying Fund. Due to the freeze of any Underlying Fund assets, including depositary receipts, the Fund's or an Underlying Fund may need to liquidate non-restricted assets in order to satisfy any Fund redemption orders. The liquidation of Underlying Fund assets during this time may also result in the Fund's or an Underlying Fund receiving substantially lower prices for its securities. Russia may implement additional retaliatory measures, which may further impair the value and liquidity of Russian securities and the ability of the Fund or an Underlying Fund to receive dividend payments. Recently, Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibits Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund may be unable to receive them.

These sanctions, the decision by Russia to suspend trading on the Moscow Exchange (MOEX) and prohibit non-resident investors from executing security sales, and other events have led to changes in certain of the Underlying Indexes of the Underlying Funds. The Underlying Fund’s Index Providers have removed Russian securities where present in an Underlying Index of an Underlying Fund. To the extent that the

10

Fund or an Underlying Fund rebalances its portfolio and trades in non-Russian securities to seek to track the investment results of its Underlying Index, this may result in transaction costs and increased tracking error. The Underlying Funds are currently restricted from trading in Russian securities, including those in their portfolios, while an Underlying Fund's Underlying Index has removed Russian securities. For Underlying Funds with Russian securities, this disparity will also lead to increased tracking error. The inability of the Underlying Fund to trade in Russian securities may adversely affect the Underlying Fund’s ability to meet its investment objective. It is unknown when, or if, sanctions may be lifted or the Underlying Fund’s ability to trade in Russian securities will resume.

Also, if an affected security is included in an Underlying Fund's Underlying Index, the Underlying Fund may, where practicable, seek to eliminate its holdings of the affected security by employing or augmenting its representative sampling strategy to seek to track the investment results of its Underlying Index. The use of (or increased use of) a representative sampling strategy may increase the Underlying Fund’s tracking error risk. If the affected securities constitute a significant percentage of an Underlying Fund's Underlying Index, the Underlying Fund may not be able to effectively implement a representative sampling strategy, which may result in significant tracking error between the Underlying Fund’s performance and the performance of its Underlying Index.

Risk of Investing in the U.S. A decrease in imports or exports, changes in trade regulations, inflation and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. Proposed and adopted policy and legislative changes in the U.S. are changing many aspects of financial, commercial, public health, environmental, and other regulation and may have a significant effect on U.S. markets generally, as well as on the value of certain securities. Governmental agencies project that the U.S. will continue to maintain elevated public debt levels for the foreseeable future. Although elevated debt levels do not necessarily indicate or cause economic problems, elevated public debt service costs may constrain future economic growth.

The U.S. has developed increasingly strained relations with a number of foreign countries. If relations with certain countries deteriorate, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord, as well as significant challenges in managing and containing the outbreak of COVID-19. If these trends were to continue, it may have an adverse impact on the U.S. economy and the issuers in which the Fund or an Underlying Fund invests.

Savings Associations Risk. Federally- and state-chartered savings associations, such as savings and loans and other “thrift” institutions, provide banking services, including mortgage lending, and operate under the supervisory authority of the Office of the Comptroller of the Currency. These associations are subject to extensive regulation affecting the scope of their activities, the prices they can charge, and the amount of capital they must maintain. This regulation can have the effect of limiting the profitability of these associations, and their profitability may change frequently. Savings associations may be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations and adverse conditions in other related markets. The historically low interest rate environment has created certain risks to savings associations as they continue to re-evaluate their business models and risk appetites to generate returns.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or an Underlying Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund or an Underlying Fund. BlackRock Institutional Trust Company, N.A. (“BTC”), the Fund's securities lending agent, will take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

Small-Capitalization Companies Risk. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the share price of an Underlying Fund that invests mostly in small-capitalization companies may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Underlying Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Sovereign and Quasi-Sovereign Obligations Risk. An investment in sovereign debt obligations involves special risks not present in corporate debt obligations. Sovereign debt includes securities issued by or guaranteed by a foreign sovereign government. The issuer of the sovereign debt that controls the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund or the Underlying Funds may have limited recourse in the event of a default. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of a sovereign debt obligation to decline. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of U.S. Treasury debt obligations and may affect the Fund's or Underlying Fund's NAV. In the past, certain emerging market countries 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. Several countries in which

11

the Fund or an Underlying Fund invests have defaulted on their sovereign debt obligations in the past or encountered downgrades of their sovereign debt obligations, and those countries (or other countries) may default or risk further downgrades in the future.

Tax Risk. Because the Fund is expected to invest in the Underlying Funds, 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.

Tracking Error Risk. The 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 the Fund's Underlying Index or an Underlying Fund's underlying index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund's or an Underlying Fund's valuation of a security at the time of calculation of the Fund's or Underlying Fund's NAV, respectively), transaction costs incurred by the Fund or its Underlying Funds, the Fund’s or its Underlying Funds' holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to the 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 the Fund or an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. 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.

U.S. Agency Debt Risk. Unsecured bonds or debentures issued by the U.S. government or one of its agencies or sponsored entities help finance U.S. governmental policies and public missions, but may be backed only by the general creditworthiness and reputation of the U.S. government agency or government sponsored entity and not the full faith and credit of the U.S. government. For example, debt issued by Fannie Mae and Freddie Mac and the Federal Home Loan Banks, provides financing, credit, and/or liquidity to the housing and mortgage markets, and is not backed by the full faith and credit of the U.S. government. In addition, debt issued by the Tennessee Valley Authority, which provides electricity generation and flood control in parts of the Southeast region of the U.S., and the Federal Farm Credit Banks, which provide credit and related services to the agricultural sector, is not backed by the full faith and credit of the U.S. government. Ginnie Mae securities and certain foreign government debt issuances guaranteed by the U.S. government, including certain issuances by Iraq and Israel, are backed by the full faith and credit of the U.S. government.

Bonds or debentures that do not carry the backing of the full faith and credit of the U.S. government are subject to more credit risk than securities that are supported by the full faith and credit of the U.S. government. If a U.S. government agency or sponsored entity that is the issuer of securities in which an Underlying Fund invests is unable to meet its obligations or ceases to exist and no plan is made for repayment of securities, the performance of an Underlying Fund will be adversely affected. There can be no assurance that the U.S. government would provide financial support to any of these U.S. governmental agencies or sponsored entities if it is not obligated to do so. In 2008, Fannie Mae and Freddie Mac were placed under the conservatorship of the U.S. government, which provided financial support to the U.S. government-sponsored entities. However, there can be no assurance that such past U.S. government support will result in support in the future. Any actual or potential disruption to a U.S. government agency or sponsored entity, or the financial condition or credit of the U.S. government, could cause the value of U.S. agency debt to decline.

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 the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). While securities guaranteed by Ginnie Mae are backed by the full faith and credit of the U.S. government, securities issued by Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or sponsored entities where it is not obligated to do so. Bonds or debentures that do not carry the backing of the full faith and credit of the U.S. government are subject to more credit risk than securities that are supported by the full faith and credit of the U.S. government. To the extent that the U.S. government has provided support to a U.S. agency or sponsored entity in the past, there can be no assurance that the U.S. government will provide support in the future if it is not obligated to do so. If a U.S. government agency or sponsored entity that is the issuer of securities in which an Underlying Fund invests is unable to meet its obligations or ceases to exist and no plan is made for repayment of securities, the performance of an Underlying Fund will be adversely affected.

mortgage-backed securities (“MBS”) represent interests in “pools” of mortgages and, due to the nature of these loans they represent, are subject to prepayment and extension risk. Prepayment risk is the risk that, during periods of falling interest rates, an issuer of mortgages and other fixed-income securities may be able to repay principal prior to the security’s maturity. This may cause an Underlying Fund to have to reinvest in securities with a lower yield or higher risk of default, resulting in a decline in an Underlying Fund's income or return potential.

12

MBS are also subject to extension risk, which is the risk that when interest rates rise, certain MBS will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in income and potentially in the value of the investment.

Because of prepayment and extension risks, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS. These securities are also subject to the risk of default on the underlying mortgage loans, particularly during periods of economic downturn.

Certain Underlying Funds seek to obtain exposure to the fixed-rate portion of U.S. agency mortgage pass-through securities primarily through to-be-announced (“TBA”) securities, or TBA transactions. TBAs refer to a commonly used mechanism for the forward settlement of U.S. agency MBS, and not to a separate type of MBS. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund, through its investments in such an Underlying Fund, to possible losses because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction.

Certain 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. Such 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 Underlying Fund’s own fees and expenses.

U.S. Government Issuers Risk. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government. Bonds or debentures that do not carry the backing of the full faith and credit of the U.S. government are subject to more credit risk than securities that are supported by the full faith and credit of the U.S. government. To the extent that the U.S. government has provided support to a U.S. agency or sponsored entity in the past, there can be no assurance that the U.S. government will provide support in the future if it is not obligated to do so. If a U.S. government agency or sponsored entity that is the issuer of securities in which the Fund invests is unable to meet its obligations or ceases to exist and no plan is made for repayment of securities, the performance of the Fund will be adversely affected. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government or U.S. government agencies and authorities may cause the value of the Fund's investments to decline. On August 5, 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 the Fund’s U.S. Treasury obligations to decline.

Valuation Risk. The price the Fund or an Underlying Fund could receive upon the sale of a security or other asset may differ from the Fund's or an Underlying Fund's valuation of the security or other asset and from the value used by its underlying index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because non-U.S. exchanges may be open on days when the Fund or an Underlying Fund does not price its shares, the value of the securities or other assets in the Fund or an Underlying Fund's portfolio may change on days or during time periods when the Fund will not be able to purchase or sell the Fund or an Underlying Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is translated into U.S. dollars at the prevailing market rates. This translation may result in a difference between the prices used to calculate the Fund's NAV and the prices used by its underlying index, which, in turn, could result in a difference between the Fund's performance and the performance of its underlying index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies. The order of the below risk factors does not indicate the significance of any particular risk factor.

Asian Economic Risk. Many Asian economies have experienced rapid growth and industrialization in recent years, but there is no assurance that this growth rate will be maintained. Other Asian economies, however, have experienced high inflation, high unemployment, currency devaluations and restrictions, and over-extension of credit. Geopolitical hostility, political instability, and economic or environmental events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund or an Underlying Fund invests. In particular, 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. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. 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

13

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 developed increasingly strained relationships with the U.S. or with China, and if these relations were to worsen, they could adversely affect Asian issuers that rely on the U.S. or China for trade. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of an Underlying Fund's investments.

Basic Materials Industry Risk. Issuers in the basic materials industry may be adversely affected by commodity price volatility, exchange rate fluctuations, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials industry are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Cash Transactions Risk. Unlike most other ETFs, an Underlying Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Underlying Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Underlying Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Underlying Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Underlying Fund’s shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Underlying Fund’s NAV. Furthermore, an Underlying Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

Central and South American Economic Risk. Certain Central and South American countries have experienced high interest rates, economic volatility, high levels of inflation, currency devaluations, government defaults and high unemployment rates. Additionally, commodities such as oil and gas, minerals and metals represent a significant percentage of the region’s exports, and the economies of countries in the region are particularly sensitive to fluctuations in commodity prices as a result. The impact of any of the foregoing events in one country could have a significant effect on the entire region.

Close-Out Risk for Qualified Financial Contracts. Regulations adopted by global prudential regulators require counterparties that are part of U.S. or foreign global systemically important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and also prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. These requirements may increase credit risk and other risks to the Fund.

Consumer Services Industry Risk. The success of firms in the consumer services industry and certain retailers (including food and beverage, general retailers, media, and travel and leisure companies) is tied closely to the performance of the domestic and international economies, interest rates, exchange rates and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Companies in the consumer services industry are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Changes in consumer demographics and preferences in the countries in which the issuers of securities held by the Fund or an Underlying Fund are located and in the countries to which they export their products may affect the success of consumer products.

Eastern European Economic Risk. An investment in issuers located or operating in Eastern Europe may subject the Fund or Underlying Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. Economies of certain Eastern European countries rely heavily on the export of commodities, including oil, gas, and certain metals. As a result, such economies may be impacted by international commodity prices and are particularly vulnerable to global demand for these products. Geopolitical events including armed conflict or war, acts of terrorism, and other instability in certain Eastern European countries may cause uncertainty in their financial markets and adversely affect the performance of the issuers to which the Fund or an Underlying Fund have exposure. The securities markets in some Eastern European countries are substantially smaller and less developed, with less government supervision and regulation of stock exchanges, and may be less liquid and more volatile than securities markets in the U.S. or Western European countries. In addition, investing in securities of issuers located or operating in Eastern Europe may involve:

■	The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in certain Eastern European countries;
■	Risks in connection with the maintenance of the Fund's or Underlying Fund's portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund or Underlying Fund;

14

■	The risk that the Fund's or Underlying Fund's ownership rights in portfolio securities could be lost through fraud or negligence as a result of the fact that ownership in shares of certain Eastern European companies is recorded by the companies themselves and by registrars, rather than a central registration system;
■	The risk that the Fund or Underlying Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because certain Eastern European banking institutions and registrars are not guaranteed by their respective governments; and
■	Risks in connection with Eastern European countries' dependence on the economic health of Western European countries and the EU as a whole.

Other risks related to investing in securities of issuers located or operating in Eastern Europe include: the potential absence of legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s or Underlying Fund's assets invested in issuers located or operating in Eastern Europe as a result of expropriation; and certain national policies which may restrict the Fund’s or Underlying Fund's investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests. In addition, Eastern European securities markets are particularly sensitive to social, political, economic, and currency events that involve Russia and may suffer heavy losses as a result of their trading and investment links to the Russian economy and currency or its neighbors.

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 in the region are impossible to predict, but could be significant. Any such disruptions caused by Russian military action or other actions (e.g., cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, sanctions, tariffs or cyberattacks on Russian entities or individuals could have a severe adverse effect on the region, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors. How long such military action and related events will last cannot be predicted. These and any related events could have significant impact on Fund performance and the value of an investment in the Fund.

European Economic Risk. The Economic and Monetary Union (the “eurozone”) of the EU requires compliance by member states that are members of the eurozone with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the eurozone. Additionally, European countries outside of the eurozone may present economic risks that are independent of the indirect effects that eurozone policies have on them. In particular, the United Kingdom's (the “U.K.”) economy may be affected by global economic, industrial and financial shifts. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of eurozone countries), 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. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have affected and may in the future adversely affect the exchange rate of the euro and may significantly affect European countries.

Responses to 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, may limit future growth and economic recovery or may 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 U.K. left the EU (“Brexit”) on January 31, 2020. The U.K. and EU reached an agreement on the terms of their future trading relationship effective January 1, 2021, which principally relates to the trading of goods rather than services, including financial services. Further discussions are to be held between the U.K. and the EU in relation to matters not covered by the trade agreement, such as financial services. The Fund faces risks associated with the potential uncertainty and consequences that may follow Brexit, including with respect to volatility in exchange rates and interest rates. 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. Brexit has also led to legal uncertainty and could lead to politically divergent national laws and regulations as a new relationship between the U.K. and EU is defined and the U.K. determines which EU laws to replace or replicate. Any of these effects could adversely affect any of the companies to which the Fund has exposure and any other assets in which the Fund invests. The political, economic and legal consequences of Brexit are not yet fully known. In the short term, financial markets may experience heightened volatility, particularly those in the U.K. and Europe, but possibly worldwide. The U.K. and Europe may be less stable than they have been in recent years, and investments in the U.K. and the EU may be difficult to value or subject to greater or more frequent volatility. In the longer term, there is likely to be a period of significant political, regulatory and commercial uncertainty as the U.K. continues to negotiate the terms of its future trading relationships.

Secessionist movements, such as the Catalan movement in Spain and the independence movement in Scotland, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. In addition, the national politics of countries in the EU have been unpredictable and subject to influence by disruptive political groups and ideologies. The governments of EU countries may

15

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 could also 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 the 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, in the region are impossible to predict, but could be significant. Any such 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, tariffs or cyberattacks on Russian entities or individuals, including politicians could have a severe adverse effect on the region, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors. How long such military action and related events will last cannot be predicted. These and any related events could have significant impact on Fund performance and the value of an investment in the Fund.

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 the Fund’s or an Underlying Fund's income and potentially in the value of the Fund’s or an Underlying Fund's investments.

Fixed-to-Floating Rate Securities Risk. Fixed-to-floating rate securities have an initial term with a fixed dividend or coupon rate and following this initial term bear a floating rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from floating rate securities held by an Underlying Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than similar fixed rate securities. The interest rate for a floating rate security resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Fixed-to-floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when an Underlying Fund needs to liquidate such securities. Benchmark interest rates, such as LIBOR or the Secured Overnight Financing Rate (“SOFR”), may not accurately track market interest rates. There is no guarantee or assurance that: (i) an Underlying Fund will be able to invest in a desired amount of fixed-to-floating rate securities, (ii) an Underlying Fund will be able to buy such securities at a desirable price, or (iii) floating rate securities in which it invests or seeks to invest will be actively traded. Any or all of the foregoing, should they occur, could negatively impact the Fund.

Hybrid Securities Risk. Hybrid securities are securities which contain characteristics of both a debt security and an equity security. Therefore, hybrid securities are subject to the risks of equity securities and risks of debt securities. The terms of hybrid instruments may vary substantially. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. Hybrid securities may also be more limited in their rights to participate in management decisions of an issuer (such as voting for the board of directors). Certain hybrid securities may be more thinly traded and less liquid than either publicly issued equity securities or debt securities, especially hybrid securities that are “customized” to meet the needs of particular investors, potentially making it difficult for the Fund to sell such securities at a favorable price or at all. Any of these features could cause a loss in market value of hybrid securities held by an Underlying Fund or otherwise adversely affect the Fund.

Illiquid Investments Risk. The 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 the 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. Liquid investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil. There can be no assurance that a security or instrument that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an illiquid investment pursuant to the Fund’s liquidity risk management program. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. An investment may be illiquid due to, among other things, the reduced number and capacity of traditional market participants to make a market in securities or instruments, the lack of an active market for such securities or instruments, capital controls, delays or limits on repatriation of local currency, or insolvency of local governments. To the extent that the Fund invests in securities or instruments with substantial market and/or credit risk, the Fund will tend to have increased exposure to the risks associated with illiquid investments. Illiquid investments may be harder to value, especially in changing markets. Although the Fund primarily seeks to redeem shares of the Fund on an in-kind basis, if the Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be magnified in a

16

rising interest rate environment or other circumstances where redemptions from the Fund may be greater than normal. Other market participants may be attempting to liquidate holdings at the same time as the Fund, causing increased supply of the Fund’s underlying investments in the market and contributing to illiquid investments risk and downward pricing pressure. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, the Fund will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund's NAV.

Investment Strategy Risk. The types of securities that qualify for inclusion in the Underlying Index can be expected to change over time. Particular risks may be elevated during periods in which the index methodology dictates higher levels of investment in particular types of investments. While the index methodology attempts to screen companies for inclusion in the Underlying Index based on financial health and a history of growing or paying above average dividends, there is no guarantee that the securities in the Underlying Index or in the Fund's portfolio will increase in value or that they won’t decline in value. In addition, if the index methodology used by the Index Provider fails to accurately predict which stocks will perform well, the Fund’s performance will suffer.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares or may invest in the Fund and hold their investment for a limited period of time. These shareholders may also pledge or loan Fund shares (to secure financing or otherwise), which may result in the shares becoming concentrated in another party. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment or that the size of the Fund would be maintained. Redemptions of a large number of Fund shares by these shareholders may adversely affect the Fund’s liquidity and net assets. To the extent the Fund permits redemptions in cash, these redemptions may force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund’s NAV, have a material effect on the market price of the Shares and increase the Fund’s brokerage costs and/or accelerate the realization of taxable income and/or gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. The Fund also may be required to sell its more liquid Fund investments to meet a large redemption, in which case the Fund’s remaining assets may be less liquid, more volatile, and more difficult to price. To the extent these large shareholders transact in shares on the secondary market, such transactions may account for a large percentage of the trading volume for the shares of the Fund and may, therefore, have a material upward or downward effect on the market price of the Fund shares. In addition, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, diluting its investment returns.

Middle Eastern Economic Risk. Many Middle Eastern countries have little or no democratic tradition, and the political and legal systems in such countries may adversely impact the companies in which the Fund or Underlying Fund invests and, as a result, the value of the Fund or Underlying Fund. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Many economies in the Middle East are highly reliant on income from the sale of oil and natural gas or trade with countries involved in the sale of oil and natural gas, and their economies are therefore vulnerable to changes in the market for oil and natural gas and foreign currency values. As global demand for oil and natural gas fluctuates, many Middle Eastern economies may be significantly impacted. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern economies may be subject to acts of terrorism, political strife, religious, ethnic or socioeconomic unrest and sudden outbreaks of hostilities with neighboring countries.

Certain Middle Eastern countries have strained relations with other Middle Eastern countries due to territorial disputes, historical animosities, international alliances, religious tensions or defense concerns, which may adversely affect the economies of these countries. Certain Middle Eastern countries experience significant unemployment, as well as widespread underemployment.

Many Middle Eastern countries periodically have experienced political, economic and social unrest as protestors have called for widespread reform. Some of these protests have resulted in a governmental regime change, internal conflict or civil war. If further regime changes were to occur, internal conflict were to intensify, or a civil war were to continue in any of these countries, such instability could adversely affect the economies of Middle Eastern countries in which the Fund or Underlying Fund invests and could decrease the value of the Fund’s or Underlying Fund's investments.

Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund's assets are invested in money market instruments, it will 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 FDIC or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than government money market funds or retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

17

Mortgage Finance Companies Risk. Mortgage finance companies provide mortgages, mortgage insurance, and related services to commercial and individual borrowers. Mortgage finance companies are subject to many of the same risks as mortgage REITs, including the credit risk of their borrowers, the risk that the value of a mortgaged property may be less than the amount owed on the property, and interest rate risk.

Mortgage REITs Risk. Mortgage REITs lend money to developers and owners of properties and invest primarily in mortgages and similar real estate interests. Mortgage REITs receive interest payments from the owners of the mortgaged properties. Accordingly, mortgage REITs are subject to the credit risk of the borrowers to whom they extend funds, which is the risk that the borrower will not be able to make timely interest and principal payments on the loan to the mortgage REIT. Mortgage REITs also are subject to the risk that the value of mortgaged properties may be less than the amounts owed on the properties. If a mortgage REIT is required to foreclose on a borrower, the amount recovered in connection with the foreclosure may be less than the amount owed to the mortgage REIT.

Mortgage REITs are subject to significant interest rate risk. During periods when interest rates are declining, mortgages are often refinanced or prepaid. Refinancing or prepayment of mortgages may reduce the yield of mortgage REITs. When interest rates decline, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to decline. In addition, rising interest rates generally increase the costs of obtaining financing, which could cause the value of a mortgage REIT’s investments to decline. A mortgage REIT’s investment in adjustable rate obligations may react differently to interest rate changes than an investment in fixed rate obligations. As interest rates on adjustable rate mortgage loans are reset periodically, yields on a mortgage REIT’s investment in such loans will gradually align themselves to reflect changes in market interest rates, causing the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

Mortgage REITs typically use leverage (and in many cases, may be highly leveraged), which increases investment risk and could adversely affect a mortgage REIT’s operations and market value in periods of rising interest rates, increased interest rate volatility, downturns in the economy, reductions in the availability of financing or deterioration in the conditions of the mortgage REIT’s mortgage-related assets.

National Closed Market Trading Risk. To the extent that the underlying securities and/or other assets held by the Fund or an Underlying Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or an Underlying Fund's shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or an Underlying Fund's quote from the closed foreign market). The impact of a closed foreign market on the Fund or an Underlying Fund is likely to be greater where a large portion of the Fund’s or an Underlying Fund's underlying securities and/or other assets trade on that closed foreign market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or an Underlying Fund's NAV that may be greater than those experienced by other ETFs.

Non-U.S. Agency Debt Risk.  The Fund and certain Underlying Funds may invest in uncollateralized bonds issued by agencies, subdivisions or instrumentalities of foreign governments. Bonds issued by these foreign government agencies, subdivisions or instrumentalities are generally backed only by the creditworthiness and reputation of the entities issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to actually provide that support. If a non-U.S. agency is unable to meet its obligations, the performance of the Fund or Underlying Fund will be adversely impacted. A non-U.S. agency’s operations and financial condition are influenced by the foreign government’s economic and other policies. Changes to the financial condition or credit rating of a foreign government may cause the value of debt issued by that particular foreign government’s agencies, subdivisions or instrumentalities to decline. During periods of economic uncertainty, the trading of non-U.S. agency bonds may be less liquid while market prices may be more volatile than prices of U.S. agency bonds. Additional risks associated with non-U.S. agency investing include differences in accounting, auditing and financial reporting standards, adverse changes in investment or exchange control regulations, political instability, which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital.

North American Economic Risk. A decrease in imports or exports, changes in trade regulations or an economic recession in any North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which the Fund or an Underlying Fund invests.

The U.S. is Canada's and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments including the implementation of tariffs by the U.S. and the renegotiation of NAFTA in the form of the United States-Mexico-Canada Agreement (“USMCA”), which replaced NAFTA on July 1, 2020, could negatively affect North America’s economic outlook and, as a result, the value of securities held by the Fund or an Underlying Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by the Fund or an Underlying Fund.

Preferred Stock Risk. Unlike interest payments on a debt security, dividend payments on preferred stock typically must be declared by the issuer's board of directors. An issuer's board of directors is generally not under any obligation to pay dividends (even if such dividends have accrued), and may suspend payment of dividends on preferred stock at any time. In the event an issuer of preferred stock experiences economic difficulties, the issuer's preferred stock may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare dividends and the fact that the preferred stock may be subordinated to other securities of the same issuer. Certain additional risks associated with preferred stock could adversely affect investments in an Underlying Fund.

Interest Rate Risk. Because many preferred stocks pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds. That is, as interest rates rise, the value of the preferred stocks held by an Underlying Fund is likely to decline. To the extent that an Underlying Fund invests a substantial portion of its assets in fixed rate preferred stocks, rising interest rates may cause the value of the Fund's investments to decline significantly.

Issuer Risk. Because many preferred stocks allow holders to convert the preferred stock into common stock of the issuer, market price of a preferred stock can be sensitive to changes in the value of the issuer's common stock. To the extent that an Underlying Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund's investments to decline.

Dividend Risk. There is a chance that the ability to pay dividends by the issuer of a preferred stock held by an Underlying Fund may deteriorate or the issuer may default (i.e., fail to make scheduled dividend payments on the preferred stock or scheduled interest payments on other obligations of the issuer not held by an Underlying Fund), which would negatively affect the value of any such holding.

Call Risk. Preferred stocks are subject to market volatility, and the prices of preferred stocks will fluctuate based on market demand. Preferred stocks often have call features that allow the issuer to redeem the security at its discretion. If a preferred stock is redeemed by the issuer, it will be removed from and Underlying Fund's underlying index. The redemption of preferred stocks having a higher than average yield may cause a decrease in the yield of an Underlying Fund and the Fund. Because an Underlying Fund's underlying index is rebalanced annually, the removal of a large number of preferred stocks during the year due to maturity, redemption, conversion or other corporate action may cause an Underlying Fund's underlying index to be periodically concentrated in a smaller number of issuers or in issuers of a particular sector or industry.

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

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 the 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 an 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.

Real Estate Investment Risk. Companies that invest in real estate (“Real Estate Companies”), such as REITs, real estate holding and operating companies, and real estate management or development companies, expose 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. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Underlying Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity and could decrease the market prices for REITs and for properties held by such REITs. The U.S. residential and commercial real estate markets may, in the future, experience and have, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Exposure to such real estate may adversely affect an Underlying Fund's performance. In addition, to the extent a Real Estate Company has its own expenses, the Underlying Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region, industry 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.

Equity REITs Risk. Certain REITs may make direct investments in real estate. These REITs are often referred to as “Equity REITs.” Equity REITs invest primarily in real properties and may earn rental income from leasing those properties. Equity REITs may also realize gains or losses from the sale of properties. Equity REITs will be affected by conditions in the real estate rental market and by changes in the value of the properties they own. A decline in rental income may occur because of extended vacancies, limitations on rents, the failure to collect rents,

19

increased competition from other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs and for the properties held by such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.

Illiquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities may be volatile. There may be less trading in Real Estate Company shares, which means that purchase and sale 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 its investments in 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 affect 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 the risks normally associated with debt financing and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Financial covenants related to a Real Estate Company’s leveraging may affect the ability of the Real Estate Company to operate effectively. In addition, investments may be subject to defaults by borrowers and tenants. Leveraging may also increase repayment risk.

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.

Operational 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 self-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 ventures 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; property damage due to events such as earthquakes, hurricanes, tornadoes, rodent, insect or disease infestations and terrorist acts; eminent domain seizures; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts, changing tastes and values, increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments and changes in tax law.

Regulatory Risk. Real estate income and values may be adversely affected by applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes, mandated closures or other commercial restrictions, reduced funding for schools, parks, garbage collection and other public services or environmental regulations also may have a major impact on real estate income and values.

Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to obtain financing either on favorable terms or at all. If the properties in which Real Estate Companies invest 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 the Real Estate Companies to make payments of interest and principal on their loans will be adversely affected.

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 distributes substantially all of its net income to its shareholders may result in the 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.

Residential and Residential-Related REIT Sub-Industry Risk. The Fund invests in REITs that have exposure to residential real estate and certain types of commercial real estate that complements residential real estate, including properties operated by healthcare providers and

20

self-storage companies. In addition to the risks related to REITs generally, investments in these REITs are subject to additional subsector-specific risks. Residential real estate may be affected by unique supply and demand factors that do not apply to other REIT sub-sectors. In addition, certain investors may already have exposure to residential real estate through ownership of a primary residence or direct ownership of rental property. The value of healthcare-focused REITs may be affected by changes in federal or state regulation of healthcare providers and reimbursement rates to healthcare providers under Medicare, Medicaid and other public or private health insurance plans. Unlike less specialized commercial real estate, when tenants vacate healthcare-related properties, the ability of property management to find replacement tenants may be impaired by the properties’ specialized healthcare uses. Investments in self-storage REITs are subject to changes in demand levels for self-storage. In addition, self-storage operators may be liable for unplanned environmental and hazardous waste compliance costs associated with operating self-storage locations.

Retail REIT Sub-Industry Risk. The Fund invests in Equity REITs that own and operate properties available for lease to retail companies. In addition to the risks related to REITs generally, investments in these retail REITs are especially sensitive to local and national economic cycles. During times of down cycles, retail REITs are subject to decreases in demand for retail rental properties, defaults by tenants, store closings, and declines in rental market rates resulting from unanticipated economic, legal, or technological developments. Retail REITs are also negatively impacted by retail company bankruptcies and restructuring as a result of, among other things, changes in consumer confidence and spending, intense competition, changes in demographics, and changes in consumer tastes and preferences.

Risk of Investing in Brazil. Investment in Brazilian issuers involves risks that are specific to Brazil, including legal, regulatory, political, currency and economic risks. Specifically, Brazilian issuers are subject to possible regulatory and economic interventions by the Brazilian government, including the imposition of wage and price controls and the limitation of imports. The economy of Brazil has historically been negatively affected by corruption scandals involving private companies and government officials, which have led to sanctions against firms. In addition, the market for Brazilian securities is directly influenced by the flow of international capital and economic and market conditions of certain countries, especially other emerging market countries in Central and South America. The Brazilian economy has historically been exposed to high rates of inflation and a high level of debt, each of which may reduce and/or prevent economic growth. A rising unemployment rate could also have the same effect.

Risk of Investing in China. Investments in Chinese issuers subject certain Underlying Funds to risks specific to China. The Chinese economy is subject to a considerable degree of economic, political and social instability.

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk in China than in many other countries of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China's growing income inequality, rapidly aging population and significant environmental issues also are factors that may affect the Chinese economy.

Government Control and Regulations. 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. There can be no assurance that these reforms will continue or that they will be effective. Despite recent reform and privatizations, government control over certain sectors or enterprises and significant regulation of investment and industry is still pervasive, including restrictions on investment in companies or industries deemed to be sensitive to particular national interests, trading of securities of Chinese issuers, foreign ownership of Chinese corporations and/or the repatriation of assets by foreign investors. Limitations or restrictions on foreign ownership of securities may have adverse effects on the liquidity and performance of the Underlying Fund and could lead to higher tracking error. Chinese government intervention in the market may have a negative impact on market sentiment, which may in turn affect the performance of the Chinese economy and the Fund’s investments. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, lack of publicly available information, and political and social instability. Chinese companies, such as those in the financial services or technology sectors, and potentially other sectors are also subject to the risk that Chinese authorities can intervene in their operations and structure, which may negatively affect the value of the Fund's investments.

Economic Risk. The Chinese economy has grown rapidly in the recent past, and there is no assurance that this growth rate will be maintained. In fact, the Chinese economy may experience a significant slowdown as a result of, among other things, a deterioration in global demand for Chinese exports, as well as a contraction in spending on domestic goods by Chinese consumers. In addition, China may experience substantial rates of inflation or economic recessions, which would have a negative effect on its economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered the performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates. Reduction in spending on Chinese products and services, institution of additional tariffs 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 Chinese issuers of securities in which the Fund invests. For example, the U.S. has added certain foreign technology companies to the U.S. Department of

21

Commerce’s Bureau of Industry and Security’s “Entity List,” which is a list of companies believed to pose a national security risk to the U.S. Actions like these may have unanticipated and disruptive effects on the Chinese economy. Any such response that targets Chinese financial markets or securities exchanges could interfere with orderly trading, delay settlement or cause market disruptions.

Expropriation Risk. The Chinese government maintains 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.

Security Risk.  China has strained international relations with Taiwan, Japan, India, Russia and other neighbors due to territorial disputes, historical animosities, defense concerns and other security concerns. Heightened tensions or an outbreak of hostilities between China and Taiwan may adversely impact China's economy as well as the global economy and the value of the Funds' or the Underlying Funds' investments. 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 the Fund invests. Relations between China's Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy. Such risks, among others, may adversely affect the value of the Fund’s investments.

Chinese Equity Markets.  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. These share mechanisms are  subject to the political and economic policies in China. The Fund may also invest in Chinese companies structured as variable interest entities (“VIEs”), which are subject to the investment risks of an associated China-based operating company. Instead of directly owning the equity securities of a Chinese company, a VIE enters into service contracts and other contracts with the Chinese company, which provide the VIE with exposure to the company. 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.

Hong Kong Political Risk.  Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the PRC under the principle of “one country, two systems.”  Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Since 1997, there have been tensions between the Chinese government and many people in Hong Kong  who perceive China as tightening of 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. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or, is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy.  Because the Fund's NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund's NAV.

Limited Information and Legal Remedies. Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. 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 Fund is not actively managed and does not select investments based on investor protection considerations.

Risk of Investing in the China Bond Market. The Fund invests directly in the China Interbank Bond Market through the northbound trading of Bond Connect. Bond Connect allows investors to trade between the mainland China and Hong Kong markets electronically, which eliminates the need for investor status and quotas that were required under previous access models. Under the prevailing regulations in the PRC, eligible foreign investors such as the Fund are allowed to invest in the bonds circulated in the China Interbank Bond Market through Bond Connect. The settlement and custody of bonds traded in the China Interbank Bond Market under Bond Connect will be effected through the settlement and custody link between CMU, as an offshore custody agent, and CCDC and SCH, as onshore custodians and clearing institutions in the PRC. All bonds traded by eligible foreign investors through Bond Connect will be registered in the name of CMU, which will hold such bonds as a nominee owner. Therefore, the Fund will be exposed to custody risks with respect to CMU. In addition, as the relevant filings, registration with the People’s Bank of China, and account opening have to be carried out by third parties, including CMU, CCDC, and SCH, the Fund is subject to the risks of default or errors and omissions on the part of such third parties and may have limited remedies or no legal recourse at all to cure such defaults, errors and omissions.

22

The precise nature and rights of the Fund as the beneficial owner of the bonds traded in the China Interbank Bond Market through CMU as nominee are relatively new and untested areas of PRC law. The definition of, and distinction between, legal ownership and beneficial ownership under PRC law differs from that in the U.S. and other developed market jurisdictions, there have been few cases involving a nominee account structure in the PRC courts and, as a result, the rights of beneficial owners are uncertain. The exact nature of the Fund's remedies and methods of the rights and interests of the Fund under PRC law are also uncertain.

Market volatility and potential lack of liquidity due to low trading volume of certain bonds in the China Interbank Bond Market may result in prices of certain bonds traded on such market to fluctuate significantly. The Fund investing in the China Interbank Bond Market is therefore subject to liquidity and volatility risks. The bid-ask spreads of the prices of such securities may be large, and the Fund may therefore incur significant costs and may suffer losses when selling such investments. The bonds traded in the China Interbank Bond Market may be difficult or impossible to sell on a timely basis or at all, which may impact the Fund's ability to acquire or dispose of such securities at their expected prices.

Investing in the China Interbank Bond Market through Bond Connect is also subject to regulatory risks. The relevant rules and regulations are subject to change, which may have potential retrospective effect, and there can be no assurance that Bond Connect or certain features or systems thereof will not be materially altered, suspended, discontinued or abolished. Furthermore, the securities regulation regimes and legal systems of the PRC and Hong Kong differ significantly and issues may arise based on these differences. In the event that the relevant authorities suspend account opening or trading on the China Interbank Bond Market, the Fund's ability to invest in the China Interbank Bond Market will be adversely affected, limited, or curtailed altogether. In such event, the Fund's ability to achieve its investment objective will be negatively affected and, after exhausting other trading alternatives, the Fund may suffer substantial losses as a result. Further, if Bond Connect is not operating, a Fund may not be able to acquire or dispose of bonds through Bond Connect in a timely manner, which could adversely affect the Fund's performance.

Trading through Bond Connect is performed through newly developed trading platforms and operational systems. There is no assurance that such systems will function as expected or will continue to be adapted to changes and developments in the market. In the event that a relevant system does not function as expected, trading through Bond Connect may be disrupted. The Fund's ability to trade through Bond Connect (and hence to pursue its investment strategy) may therefore be adversely affected. In addition, where the Fund invests in the China Interbank Bond Market through Bond Connect, it may be subject to risks of delays inherent in the order placing and/or settlement systems.

Bond Connect trades are settled in Chinese currency, the renminbi (“RMB”). This means that the Fund will be exposed to currency risk, and it cannot be guaranteed that investors will have timely access to a reliable supply of RMB. The RMB consists of an onshore RMB (“CNY”) and an offshore RMB (“CNH”). The CNY is the official currency of the PRC and is the currency of denomination for all financial transactions between individuals, the state and corporations in the PRC. Hong Kong is the first jurisdiction to allow for the accumulation of RMB deposits in the form of CNH outside the PRC. Since 2010, the CNH market is traded officially and regulated jointly by the Hong Kong Monetary Authority and the PBOC. While CNY and CNH are the same currency, they are traded in different and separate markets. Therefore, CNY and CNH can be subject to different liquidity constraints and market forces, meaning their valuations can vary. The RMB-denominated bonds included in the Underlying Index use CNY as the base currency. As a result, to the extent that the Fund holds RMB-denominated instruments in CNH, it could be subject to tracking error and potential foreign exchange transaction costs associated with converting from CNH to CNY (and vice versa).

Under prevailing tax regulations, a 10% withholding tax is imposed on PRC-sourced dividends and interest from non-government bonds paid to the Fund unless the rate is reduced under an applicable tax treaty. Value Added Tax (“VAT”) is levied on certain income derived by the Fund, including interest income from non-government bonds and trading gains, unless specifically exempted by the PRC tax authorities. VAT exemptions currently apply to debt securities traded in the China Interbank Bond Market. On November 22, 2018, the PRC’s Ministry of Finance and State Administration of Taxation jointly issued Circular 108 providing foreign institutional investors with a temporary exemption from withholding income tax and VAT with respect to interest income derived from non-government bonds in the domestic bond market for the period from November 7, 2018 to November 6, 2021. On November 26, 2021, the PRC's Ministry of Finance and State Administration of Taxation jointly issued Circular 34 to extend the tax exemption period provided in Circular 108 to December 31, 2025. Circular 108 is silent on the PRC tax treatment with respect to non-government bond interest derived prior to November 7, 2018. There is a risk the PRC tax authorities may withdraw the temporary tax exemptions in the future and seek to collect withholding income tax and VAT on interest income from non-government bonds to the Fund without prior notice. If the tax exemptions are withdrawn, any taxes arising from or to the Fund may be directly borne by or indirectly passed on to the Fund, which may result in a substantial impact to its NAV. As with any NAV adjustment, investors may be advantaged or disadvantaged depending on when the investors purchased or sold shares of the Fund. Any changes in PRC tax law, future clarifications thereof, and/or subsequent retroactive enforcement by the PRC tax authorities may result in a loss which could be material to the Fund. BFA will keep the provisioning policy for tax liability under review and may, in its discretion from time to time, make a provision for potential tax liabilities if in its opinion such provision is warranted or as further publicly clarified by the PRC.

Risk of Investing in Developed Countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other

23

sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund or an Underlying Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund or an Underlying Fund has exposure. Heavy regulation of certain markets, including 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. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in the U.K. Investment in U.K. issuers may subject the Fund or an Underlying Fund to regulatory, political, currency, security, and economic risks specific to the U.K. The U.K.’s economy relies heavily on the export of financial services to the U.S. and other European countries. A prolonged slowdown in the financial services sector may have a negative impact on the U.K.’s economy. In the past, the U.K. has been a target of terrorism. Acts of terrorism in the U.K. or against U.K. interests may cause uncertainty in the U.K.’s financial markets and adversely affect the performance of the issuers to which the Fund or an Underlying Fund has exposure. Secessionist movements, such as the Catalan movement in Spain and the independence movement in Scotland, may have an adverse effect on the U.K. economy.

On January 31, 2020, the U.K. officially left the EU (“Brexit”), subject to a transitional period that ended December 31, 2020. The U.K. and EU have reached an agreement on the terms of their future trading relationship effective January 1, 2021, which principally relates to the trading of goods rather than services, including financial services. Further discussions are to be held between the U.K. and the EU in relation to matters not covered by the trade agreement, such as financial services. The Fund faces risks associated with the potential uncertainty and consequences that may follow Brexit, including with respect to volatility in exchange rates and interest rates. 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. Brexit has also led to legal uncertainty and could lead to politically divergent national laws and regulations as a new relationship between the U.K. and EU is defined and the U.K. determines which EU laws to replace or replicate. Any of these effects of Brexit could adversely affect any of the companies to which the Fund has exposure and any other assets that the Fund invests in. The political, economic and legal consequences of Brexit are not yet known. In the short term, financial markets may experience heightened volatility, particularly those in the U.K. and Europe, but possibly worldwide. The U.K. and Europe may be less stable than they have been in recent years, and investments in the U.K. and the EU may be difficult to value or subject to greater or more frequent volatility. In the longer term, there is likely to be a period of significant political, regulatory and commercial uncertainty as the U.K. continues to negotiate the terms of its future trading relationship with the EU.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunications companies in which the Fund or the Underlying Funds invests. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The domestic telecommunications market is characterized by increasing competition and regulation by various state and federal regulatory authorities. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Telecommunications providers are generally required to obtain franchises or licenses in order to provide services in a given location. Licensing and franchise rights in the telecommunications sector are limited, which may provide an advantage to certain participants. Limited availability of such rights, high barriers to market entry and regulatory oversight, among other factors, have led to consolidation of companies within the sector, which could lead to further regulation or other negative effects in the future.

Threshold/Underinvestment Risk. If certain aggregate and/or fund-level ownership thresholds are reached through transactions undertaken by BFA, its affiliates or an Underlying Fund, or as a result of third-party transactions or actions by an issuer or regulator, the ability of BFA and its affiliates on behalf of clients (including an Underlying Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired.  The capacity of an Underlying Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of an Underlying Fund’s portfolio holdings compared to the performance of such a fund's underlying index. This may increase the risk of an Underlying Fund being underinvested to the Underlying Index and increase the risk of tracking error.

For example, in certain circumstances where an Underlying Fund invests in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, is subject to corporate or regulatory ownership restrictions, or invests in certain futures or other derivative transactions, there may be limits on the aggregate and/or fund-level  amount invested or voted by BFA and its affiliates for their proprietary accounts and for client accounts (including an Underlying Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BFA and its affiliates, an Underlying Fund or other client accounts to suffer disadvantages or business restrictions.

U.S. Economic Risk. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, certain country or countries in which an Underlying Fund invests. As a result, economic conditions of such countries 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 such countries and, as a result, securities to which an Underlying Fund has exposure.

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 the Fund's or an Underlying Fund's U.S. Treasury obligations to decline. On August 5, 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 the Fund’s U.S. Treasury obligations to decline.

Utilities Sector Risk. Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition, and governmental limitations on rates charged to consumers. 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. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

A Further Discussion of Principal Investment Strategies

Overview

The Fund allocates and reallocates its assets among the Underlying Funds consistent with the allocation and reallocation of securities in the Underlying Index as determined by Morningstar. In addition to investing in the Underlying Funds, the Fund may borrow, lend its portfolio securities to brokers, dealers and financial institutions, and may invest the collateral in certain short-term instruments, either directly or through one or more money market funds, as described in greater detail in the Fund's SAI.

Certain Underlying Funds may invest in non-U.S. securities, emerging markets securities and debt instruments, which are subject to additional risks, as described in this Prospectus and in the Fund's SAI. The investment model for the Underlying Index is intended to represent a fixed allocation strategy designed to deliver high current income.

The Underlying Funds

The Fund seeks to track the investment results of an index composed of underlying equity, fixed-income and other income funds that collectively seek to deliver high current income while providing an opportunity for capital appreciation. Each Underlying Fund generally holds assets that form a sub-set of the securities comprising the Underlying Index. The Fund's allocation of assets to the Underlying Funds will generally closely reflect the allocation weights represented in the Underlying Index.

The following table lists each Fund's investments and asset allocation as of July 31, 2022. BFA allocates the Fund’s assets among the Underlying Funds in accordance with the Fund’s investment objective and policies. Any remaining assets are allocated to the BlackRock Cash Funds. BFA is not required to invest the Fund’s assets in all of the Underlying Funds or in any particular percentage in any given Underlying Fund.

BlackRock Cash Funds: Institutional Fund	18.46%

Note: The allocation percentages may not add up to, or may appear to exceed, 100% due to rounding.

In managing each of the Underlying Funds, BFA uses a representative sampling index strategy. Representative sampling is an indexing strategy that involves investing in a representative sample of securities that collectively have an investment profile similar to a specified benchmark index. Securities selected for the Underlying Funds are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the applicable underlying index. The Underlying Funds may or may not hold all of the securities that are included in their respective underlying indexes and may hold certain securities that are not included in their respective underlying indexes. Additional information regarding the Underlying Funds and their principal investment strategies is provided below.

iShares International Select Dividend ETF

27

The iShares International Select Dividend ETF seeks to track the investment results of the Dow Jones EPAC Select Dividend Index (the “Underlying Index”), which measures the performance of 100 high dividend-paying companies in the EPAC (Europe, Pacific, Asia and Canada) region, which covers developed markets excluding the U.S. Dividend yield is calculated using a stock’s indicated annual dividend (not including any special dividends) divided by its price. S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”) begins with the S&P EPAC BMI and the S&P Canada BMI indices, excluding real estate investment trusts (“REITs”). The Index Provider selects new constituents based on the following criteria: (i) the company must have paid dividends in each of the previous three years; (ii) the company’s current year trailing twelve months dividend per share ratio must be greater than or equal to its three-year average dividend per share ratio; (iii) the company’s five-year average dividend coverage ratio must be greater than or equal to two-thirds of the five-year average dividend coverage ratio of the corresponding S&P BMI^® country index, or greater than 118%, whichever is greater; (iv) the company’s securities must have a three-month average daily dollar trading value of at least $3 million; (v) the company's securities must have a non-negative trailing 12-month earnings per share (EPS); and (vi) the company's securities must have a float-adjusted market capitalization of at least $1 billion. The Index Provider next ranks the stocks based on dividend yield and selects 100 constituents by first including all existing constituents ranked in the top 200 and next by selecting non-constituent stocks in rank order. The Underlying Index is weighted based on dividend yield. However, the Index Provider applies a capping methodology that limits the dividend yield values used to calculate constituent weights to 20%, the weights of individual securities to the lower of 10% or five times the constituent’s float-adjusted market capitalization weight, and the aggregate weight of constituents within each Global Industry Classification Standard sector and each country of domicile to 30%. The Underlying Index is reviewed annually; however, component changes may take place on a monthly basis.

As of April 30, 2022, the Underlying Index was composed of securities of companies in the following countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, South Korea, Spain, Sweden, Switzerland and the United Kingdom (the “U.K.”). The Fund invests in non-U.S. securities, which may in some cases not produce qualifying dividend income. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. As of April 30, 2022, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

iShares J.P. Morgan EM Local Currency Bond ETF

The iShares J.P. Morgan EM Local Currency Bond ETF seeks to track the investment results of the J.P. Morgan GBI-EM Global Diversified 15% Cap 4.5% Floor Index (the “Underlying Index”), which tracks the performance of local currency-denominated sovereign bond markets of emerging market countries. All bonds included in the Underlying Index are selected according to a set of rule-based inclusion criteria regarding issue size, bond type, maturity, and liquidity. The securities included in the Underlying Index are rebalanced on the last weekday of the month. Eligible countries included in the Underlying Index are determined by JPMorgan Chase & Co. or its affiliates (the “Index Provider” or “J.P. Morgan”) based on the Index Provider’s definition of emerging market countries.

Eligible issuer countries must have (1) gross national income (“GNI”) below the Index Income Ceiling (“IIC”) for three consecutive years or (2) an Index Purchasing Power Parity Ratio (the “IPR”) below the EM IPR threshold, each as defined by the Index Provider, for three consecutive years. An existing country may be considered for removal from the Underlying Index if its GNI per capita is above the IIC for three consecutive years and its long-term sovereign credit rating from Standard & Poor’s Global Ratings (“S&P Global”), Moody’s Investors Service, Inc. (“Moody’s”), and Fitch Ratings, Inc. (“Fitch”) is A-/A3/A- or above for three consecutive years. For purposes of compiling the Underlying Index, individual country weights are capped at maximum 15% and floored at minimum 4.5%. Eligible individual securities must have a minimum face amount outstanding of U.S. $1 billion equivalent for onshore local currency bonds and U.S. $500 million for global bonds (offshore currency linked bonds). All component securities must have at least 2.5 years to maturity from the inclusion date and  a remaining maturity of 6 months or greater at the time of rebalancing to remain eligible for the Underlying Index.

Floating-rate issues, capitalization/amortizing bonds, and bonds with callable, puttable or convertible features are not eligible for inclusion in the Underlying Index.

As of October 31, 2021, the Underlying Index included securities issued by Brazil, Chile, China, Colombia, Czech Republic, Dominican

28

Republic, Egypt, Hungary, Indonesia, Malaysia, Mexico, Peru, the Philippines, Poland, Romania, Russia, Serbia, South Africa, Thailand, Turkey and Uruguay. Russian securities were removed from the Underlying Index effective March 31, 2022.

iShares J.P. Morgan USD Emerging Markets Bond ETF

The iShares J.P. Morgan USD Emerging Markets Bond ETF seeks to track the investment results of the J.P. Morgan EMBI^® Global Core Index (the “Underlying Index”), which is a broad, diverse U.S. dollar-denominated emerging markets debt benchmark that tracks the total return of actively traded external debt instruments in emerging market countries. The methodology is designed to distribute the weight of each country within the Underlying Index by limiting the weights of countries with higher debt outstanding and reallocating this excess to countries with lower debt outstanding.

The Underlying Index was composed of 58 countries as of October 31, 2021. As of October 31, 2021, the Underlying Index’s five highest weighted countries were Indonesia, Mexico, Qatar, Saudi Arabia and the United Arab Emirates.

The Underlying Index may change its composition and weighting monthly upon rebalancing. The Underlying Index includes both fixed-rate and floating-rate instruments issued by sovereign and quasi-sovereign entities from index-eligible countries. Quasi-sovereign entities are defined as entities that are 100% guaranteed or 100% owned by the national government and reside in the index eligible country. To be considered for inclusion in the Underlying Index, instruments must (i) be denominated in U.S. dollars, (ii) have a current face amount outstanding of $1 billion or more, (iii) have at least 2.5 years until maturity to be eligible for inclusion and, at each subsequent rebalance, have at least one year until maturity to remain in the index, (iv) be able to settle internationally through Euroclear or another institution domiciled outside the issuing country and (v) have bid and offer prices that are available on a daily and timely basis sourced from a third party valuation vendor. As of October 31, 2021, the Underlying Index consisted of both investment-grade and non-investment-grade bonds (commonly referred to as “junk bonds”), each as defined by JPMorgan Chase & Co. (the “Index Provider” or “J.P. Morgan”). Convertible bonds are not eligible for inclusion in the Underlying Index. The Underlying Index is market-value weighted and is rebalanced monthly on the last business day of the month.

Eligible issuer countries must have (1) gross national income (“GNI”) below the Index Income Ceiling (“IIC”) for three consecutive years or (2) an Index Purchasing Power Parity Ratio (the “IPR”) below the emerging market IPR threshold, each as defined by the Index Provider, for three consecutive years.

iShares MBS ETF

The iShares MBS ETF seeks to track the investment results of the Bloomberg U.S. MBS Index (the “Underlying Index”), which measures the performance of investment-grade (as determined by Bloomberg Index Services Limited (the “Index Provider” or “Bloomberg”)) mortgage-backed pass-through securities (“MBS”) issued or guaranteed by U.S. government agencies or sponsored entities. The Underlying Index includes fixed-rate MBS issued by the Government National Mortgage Association (“GNMA” or “Ginnie Mae”), Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”) that have 30-, 20-, or 15-year maturities. All securities in the Underlying Index must have a remaining weighted average maturity of at least one year. In addition, the securities in the Underlying Index must be denominated in U.S. dollars and must be non-convertible. The Underlying Index is market capitalization-weighted and the securities in the Underlying Index are updated on the last business day of each month.

As of February 28, 2022, approximately 100% of the bonds represented in the Underlying Index were U.S. agency MBS. Most transactions in MBS occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement (to-be-announced (“TBA”) transactions). The Fund may enter into such contracts for fixed-rate pass-through securities on a regular basis. The Fund, pending settlement of such contracts, will invest its assets in liquid, short-term instruments, including shares of money market funds advised by BFA or its affiliates. The Fund will assume its pro rata share of the fees and expenses of any money market fund that it may invest in, in addition to the Fund's own fees and expenses. The Fund may also acquire interests in mortgage pools through means other than such standardized contracts for future delivery.

iShares Mortgage Real Estate ETF

The iShares Mortgage Real Estate ETF seeks to track the investment results of the FTSE Nareit All Mortgage Capped Index (the “Underlying Index”), which measures the performance of the residential and commercial mortgage real estate, mortgage finance and savings associations sectors of the U.S. equity market, as defined by FTSE International Limited (the “Index Provider” or “FTSE”).  The Underlying Index generally measures the performance of the residential and commercial mortgage real estate sector and generally invests all of its assets in REITs. If the number of constituents in the Underlying Index falls below 20, FTSE will consider companies from the mortgage finance and savings associations sectors for inclusion in the Underlying Index, and each company in the mortgage finance and savings associations sectors will be capped at 3% of the Underlying Index, and these sectors in the aggregate will not exceed 30% of the Underlying Index. As of March 31, 2022, approximately 100% of the market capitalization of the Underlying Index is represented by REITs. As of March 31, 2022, the Underlying Index includes 33 component securities. The components of the Underlying Index are likely to change over time.

iShares Preferred and Income Securities ETF

The iShares Preferred and Income Securities ETF seeks to track the investment results of the ICE Exchange-Listed Preferred & Hybrid Securities Index (the “Underlying Index”), which measures the performance of a select group of exchange-listed, U.S. dollar-denominated preferred securities, hybrid securities and convertible preferred securities listed on the NYSE or the Nasdaq Capital Market. The Underlying Index includes issuances of preferred stocks with amounts outstanding over $100 million, convertible preferred stock with at least $50 million face amount outstanding, and hybrid securities with at least $250 million face amount outstanding, that meet minimum maturity and other requirements, as applicable, as determined by ICE Data Indices (the “Index Provider” or “ICE Data”).

In general, preferred stock is a class of equity security that pays a specified dividend that must be paid before any dividends can be paid to common stockholders and takes precedence over common stock in the event of a company’s liquidation. In general, a “hybrid” security refers to a security which combines both debt and equity characteristics. In general, hybrid securities included in the Underlying Index, like traditional preferred stock, have preference over the common stock within an issuer’s capital structure, and are issued and traded in a similar manner to traditional preferred stock. Like debt securities and preferred stock (but unlike common stock), issuers of hybrid securities included in the Underlying Index may make fixed, periodic payments to the holders of such securities. Like preferred stock, issuers of hybrid securities included in the Underlying Index have the ability to defer dividend payments and to extend such securities’ maturity dates.

Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights. Preferred stocks have economic characteristics similar to fixed-income securities. Preferred stocks and hybrid securities generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate.

Additionally, preferred stocks and hybrid securities often have a liquidation value that generally equals the original purchase price of such security at the date of issuance. The Underlying Index may include many different categories of preferred stock and hybrid securities, such as floating and fixed rate preferreds, fixed-to-floating rate securities, callable preferreds, convertible preferreds, cumulative and non-cumulative preferreds, certain capital securities, trust preferreds or various other preferred stock and hybrid securities. The total allocation to an individual issuer across the entire Underlying Index is limited to 4.75%. The Underlying Index uses a market capitalization weighted methodology subject to certain constraints and is rebalanced monthly.

The Underlying Index may include large-, mid- or small-capitalization companies and includes preferred stocks and hybrid securities of non-U.S. issuers. As of March 31, 2022, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

iShares U.S. Real Estate ETF

30

The iShares U.S. Real Estate ETF seeks to track the investment results of the Dow Jones U.S. Real Estate Capped Index (the “Underlying Index”), which measures the performance of the real estate sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index uses a capping methodology to limit the weight of the securities of any single issuer (as determined by SPDJI) to a maximum of 10% of the Underlying Index. Additionally, the Underlying Index constrains at each quarterly review: (i) the weight of any single issuer to a maximum of 10%, and (ii) the aggregate weight of all issuers that individually exceed 4.50% of the index weight to a maximum of 22.50%. Between scheduled quarterly index reviews, the Underlying Index is rebalanced at the end of any day on which all issuers that individually constitute more than 5% of the weight of the Underlying Index constitute more than 25% of the weight of the Underlying Index in the aggregate. In implementing this capping methodology, SPDJI may consider two or more companies as belonging to the same issuer where there is reasonable evidence of common control.

As of March 31, 2022, a significant portion of the Underlying Index is represented by securities of companies in the real estate investment trust (“REIT”) industry or sector. The components of the Underlying Index are likely to change over time.

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Fund. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund's investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except 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 Trustees who are not “interested persons” of the Trust).

For the fiscal year ended July 31, 2022, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.25%. BFA has contractually agreed to waive a portion of its management fee in order to limit the Fund’s total annual fund operating expenses after the fee waiver to 0.60% through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA. In addition, BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit 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.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is an indirect wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”). As of September 30, 2022, BFA and its affiliates provided investment advisory services for assets in excess of $8.0 trillion. BFA and its affiliates trade and invest for their own accounts in the actual securities and types of securities in which the Fund may also invest, which may affect the price of such securities.

A discussion regarding the basis for the approval by the Trust's Board of Trustees (the “Board”) of the Investment Advisory Agreement with BFA is available in the Fund's Annual Report for the period ended July 31.

Portfolio Managers. Jennifer Hsui, Greg Savage, Paul Whitehead and Amy Whitelaw are primarily responsible for the day-to-day management of the Fund. The Portfolio Managers are responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of their respective portfolio management teams to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of their respective portfolio management teams who have more limited responsibilities.

31

Jennifer Hsui has been employed by BFA or its affiliates as a senior portfolio manager since 2007. Prior to that, Ms. Hsui was a portfolio manager from 2006 to 2007 for Barclays Global Fund Advisors (“BGFA”). Ms. Hsui has been a Portfolio Manager of the Fund since 2022.

Greg Savage has been employed by BFA or its affiliates as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA. Mr. Savage has been a Portfolio Manager of the Fund since 2022.

Paul Whitehead has been with BlackRock since 1996, including his years with Barclays Global Investors (“BGI”), which merged with BlackRock in 2009. Mr. Whitehead has been employed by BlackRock as a Managing Director since 2010 and a Director from 2009 to 2010. Mr. Whitehead was employed by BGI as Principal from 2002 to 2009. Mr. Whitehead has been a Portfolio Manager of the Fund since 2022.

Amy Whitelaw has been with BlackRock since 1999, including her years with BGI, which merged with BlackRock in 2009. Ms. Whitelaw has been employed by BFA or its affiliates as a portfolio manager since 2009 and has been a Portfolio Manager of the Fund since 2022.

The Fund's SAI provides additional information about the Portfolio Managers' compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers' ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. Citibank, N.A. (“Citibank”) is the administrator, custodian and transfer agent for the Fund. JPMorgan Chase Bank, N.A. serves as custodian for the Fund in connection with certain securities lending activities.

Conflicts of Interest. The investment activities of BFA and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Fund. BFA and its Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more Affiliates act, or may act, as an investor, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, trader, lender, index provider, agent and/or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. The Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has significant debt or equity investments or other interests. The Fund may also invest in issuances (such as structured notes) by entities for which an Affiliate provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase or distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. BFA or one or more Affiliates may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund. This may include transactions in securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”)). The trading activities of BFA and these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate having positions in certain securities that are senior or junior to, or have interests different from or adverse to, the securities that are owned by the Fund.

Neither BlackRock nor any Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate may compete with the Fund for appropriate investment opportunities. The results of the Fund's investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by BlackRock or an Affiliate, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

In addition, the Fund may, from time to time, enter into transactions in which BFA or an Affiliate or its or their directors, officers, employees or clients have an adverse interest. Furthermore, transactions undertaken by clients advised or managed by BFA or its Affiliates may adversely impact the Fund. Transactions by one or more clients or by BFA or its Affiliates or their directors, officers or employees may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to BFA or one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Under a securities lending program approved by the Board, the Fund has retained BTC, an Affiliate of BFA, to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the securities lending agent will receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for

32

the loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

Under an ETF Services Agreement, the Fund has retained BlackRock Investments, LLC (the “Distributor” or “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 Fund (“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, 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.

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 the Fund. The price, availability, liquidity, and (in some cases) expense ratio of the Fund may be impacted by purchases and sales of the Fund by BlackRock and/or its advisory clients.

The activities of BFA and its Affiliates and their respective directors, officers or employees may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange or otherwise in the secondary market. The Fund's shares trade under the ticker symbol “IYLD.”

Buying or selling Fund shares on an exchange or other secondary market involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the Fund’s trading volume and market liquidity, and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The Fund's spread may also be impacted by the liquidity or illiquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund's shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays (or the days on which they are 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. The Fund’s primary listing exchange is Cboe BZX.

Section 12(d)(1) of the 1940 Act generally restricts investments by investment companies, including foreign and unregistered investment companies, in the securities of other investment companies.  For example, a registered investment company (the “Acquired Fund”), such as the Fund, may not knowingly sell or otherwise dispose of any security issued by the Acquired Fund to any investment company (the “Acquiring Fund”) or any company or companies controlled by the Acquiring Fund if, immediately after such sale or disposition: (i) more than 3% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and any company or companies controlled by the Acquiring Fund, or (ii) more than 10% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and other

33

investment companies and companies controlled by them. Although SEC rules may permit registered investment companies and unit investment trusts (“Investing Funds”) that enter into an investment agreement with the Trust to invest in iShares funds beyond the limits set forth in Section 12(d)(1) of the 1940 Act subject to certain terms and conditions, the Fund does not permit such investments. Accordingly, Investing Funds must adhere to the limits set forth in Section 12(d)(1) of the 1940 Act when investing in the Fund. In addition, foreign investment companies are permitted to invest in the Fund only up to the limits set forth in Section 12(d)(1), subject to any applicable SEC no-action relief.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of, and holds legal title to, all outstanding shares of the Fund.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors.

Determination of Net Asset Value. The NAV for each Fund normally is determined once daily Monday through Friday, generally as of the close of regular trading hours of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets, which includes the values of the Underlying Fund shares in which the Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund is determined pursuant to BFA’s valuation policies and procedures. BFA has been designated by the Board as the valuation designee for the Fund pursuant to Rule 2a-5 under the Investment Company Act.

Equity securities and other equity instruments for which market quotations are readily available are valued at market value, which is generally determined using the last reported official closing price or, if a reported closing price is not available, the last traded price on the exchange or market on which the security or instrument is primarily traded at the time of valuation. Shares of underlying open-end funds (including money market funds) are valued at net asset value. Shares of underlying exchange-traded closed-end funds or other ETFs are valued at their most recent closing price.

Generally, trading in non-U.S. securities and money market instruments is substantially completed each day at various times prior to the close of regular trading hours of the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, BFA will fair value the Fund’s investments in accordance with its policies and procedures. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of trading or other reasons, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event 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, the Fund.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least once a year by the Fund. The Fund generally distributes its net capital gains, if any, to shareholders annually. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, 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, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the U.S., which includes an exchange of information program, or if the stock with respect to which the dividend was paid is readily tradable on an established U.S. securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC. Additionally, it is expected that dividends received by the 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, the Fund may report dividends eligible for a 20% “qualified business income” deduction for non-corporate U.S. shareholders to the extent the Fund’s income is derived from ordinary REIT dividends, reduced by allocable Fund expenses.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

Fund distributions, to the extent attributable to dividends from U.S. corporations, will be eligible for the dividends received deduction for Fund shareholders that are corporations, subject to certain hedging and holding requirements.

35

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

Short term capital gains earned by an Underlying Fund will be ordinary income when distributed to the Fund and will not be offset by the Fund's capital losses. Because the Fund is expected to invest in the Underlying Funds, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as “wash sales”. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Dividends, interest and capital gains earned by an Underlying Fund with respect to securities issued by non-U.S. issuers may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If more than 50% of the total assets of an Underlying Fund at the close of a year consists 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 a Fund at the close of the year consists of foreign securities, or, at the close of each quarter, shares of Underlying Funds), a Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or an Underlying Fund.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are neither a resident nor a citizen of the U.S. or if you are a non-U.S. corporation (other than a pass-through entity to the extent owned by U.S. persons), the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the 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 U.S. Internal Revenue Service (“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 that an applicable 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.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income. In addition, you may lose the ability to use foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

If you are a resident or a citizen of the U.S., by law, backup withholding at a 24% rate will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares Are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

36

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax advisor about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's Distributor, an affiliate of BFA. An Authorized Participant is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities, assets or other positions (a “creation basket”), and an amount of cash (including any cash representing the value of substituted securities, assets or other positions), if any, which together approximate the holdings of the Fund in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities, assets or other positions (a “redemption basket”) held by the Fund and an amount of cash (including any portion of such securities for which cash may be substituted). The Fund may, in certain circumstances, offer Creation Units partially or solely for cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund. Creation and redemption baskets may differ and the Fund may accept “custom baskets.” More information regarding custom baskets is contained in the Fund's SAI.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

Only an Authorized Participant may create or redeem Creation Units with the Fund. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Fund.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the 1933 Act. Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund's SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. 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 subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor or its agent distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 1 University Square Drive, Princeton, NJ 08540.

BFA or its affiliates make payments to broker-dealers, registered investment advisers, banks or other intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, data provision services, or their making shares of the Fund and certain other iShares funds available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments or other financial incentives it is eligible to receive. Therefore, such payments or other financial incentives offered or made to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund's and each Underlying Fund's SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years.

The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with each Fund's financial statements, in each Fund's Annual Report (available upon request).
