The Markets in Review

Dear Shareholder,

The 12-month reporting period as of October 31, 2021 was a remarkable period of adaptation and recovery, as the global economy dealt with the implications of the coronavirus (or “COVID-19”) pandemic. The United States began the reporting period as the initial reopening-led economic rebound was beginning to slow. Nonetheless, the economy continued to grow at a solid pace for the reporting period, eventually regaining the output lost from the pandemic. However, a rapid rebound in consumer spending pushed up against supply constraints and led to elevated inflation.

Equity prices rose with the broader economy, as the implementation of mass vaccination campaigns and passage of two additional fiscal stimulus packages further boosted stocks, and many equity indices neared or surpassed all-time highs late in the reporting period. In the United States, returns of small-capitalization stocks, which benefited the most from the resumption of in-person activities, outpaced large-capitalization stocks. International equities also gained, as both developed and emerging markets continued to recover from the effects of the pandemic.

The 10-year U.S. Treasury yield (which is inversely related to bond prices) had fallen sharply prior to the beginning of the reporting period, which meant bonds were priced for extreme risk avoidance and economic disruption. Despite expectations of doom and gloom, the economy expanded rapidly, stoking inflation concerns in early 2021, which led to higher yields and a negative overall return for most U.S. Treasuries. In the corporate bond market, support from the U.S. Federal Reserve (the “Fed”) assuaged credit concerns and led to solid returns for high-yield corporate bonds, outpacing investment-grade corporate bonds.

The Fed remained committed to accommodative monetary policy by maintaining near-zero interest rates and by reiterating that inflation could exceed its 2% target for a sustained period without triggering a rate increase. In response to rising inflation late in the period, the Fed changed its market guidance, raising the possibility of higher rates in 2022 and reducing bond purchasing beginning in late 2021.

Looking ahead, we believe that the global expansion will continue to broaden as Europe and other developed market economies gain momentum, although the Delta variant of the coronavirus remains a threat, particularly in emerging markets. While we expect inflation to remain elevated in the medium-term as the expansion continues, we believe the recent uptick owes more to temporary supply disruptions than a lasting change in fundamentals. The change in Fed policy also means that moderate inflation is less likely to be followed by interest rate hikes that could threaten the economic expansion.

Overall, we favor a moderately positive stance toward risk, with an overweight in equities. Sectors that are better poised to manage the transition to a lower-carbon world, such as technology and health care, are particularly attractive in the long-term. U.S. small-capitalization stocks and European equities are likely to benefit from the continuing vaccine-led restart, while Chinese equities stand to gain from a more accommodative monetary and fiscal environment as the Chinese economy slows. We are underweight long-term credit, but inflation-protected U.S. Treasuries, Asian fixed income, and emerging market local-currency bonds offer potential opportunities. We believe that international diversification and a focus on sustainability can help provide portfolio resilience, and the disruption created by the coronavirus appears to be accelerating the shift toward sustainable investments.

In this environment, our view is that investors need to think globally, extend their scope across a broad array of asset classes, and be nimble as market conditions change.

U.S. Treasury Bond Market Overview

Short- and intermediate-term U.S. Treasuries declined for the 12 months ended October 31, 2021 (“reporting period”). The ICE Bank of America 1 – 10 year U.S. Treasury Index, which tracks short- and intermediate-maturity U.S. Treasuries, returned -1.48%.

The U.S. economy continued to recover from the effects of the coronavirus pandemic, growing at a brisk pace during the reporting period. Driven by strong consumer spending and significant fiscal and monetary stimulus, U.S. growth outpaced most other developed economies. An ongoing COVID-19 vaccination program helped accelerate the easing of pandemic-related restrictions, and consumers returned to activities that were previously curtailed, such as travel, restaurant dining, and in-person shopping. Spending on goods also remained elevated, leading imports to rise to an all-time high.

However, this robust consumer demand combined with continued pandemic-related disruptions to the global supply chain led to significantly higher inflation. Similarly, in the labor market, the reopening economy and pent-up demand meant that hiring accelerated, and the unemployment rate fell substantially. Nonetheless, total employment remained notably below pre-pandemic levels and job openings reached a record high despite rising wages. Elevated demand drove an increase in industrial production, although rising commodities prices and supply delays constrained growth, particularly late in the reporting period. The emergence of the highly contagious Delta variant, which was responsible for a significant rise in cases beginning late in summer 2021, also weighed on the economy.

The U.S. Federal Reserve Bank (“Fed”) continued to keep short-term interest rates at near-zero levels and maintained a significant bond-buying program for U.S. Treasuries and mortgage-backed securities, although it discontinued its corporate bond purchasing program. The Fed indicated that it would begin slowing its bond buying activities late in 2021 and signaled that an interest rate increase could be possible in 2022. However, the improving employment environment and a sharp rise in inflation led investors to anticipate a more accelerated tightening of monetary policy. Trading activity showed that investors view multiple interest rate increases as probable in 2022.

U.S. Treasuries declined as inflation increased and investors shifted toward equities and lower-rated bonds. Rising domestic inflation expectations pressured U.S. Treasuries, which typically lose value in an inflationary environment. U.S. Treasury yields (which move inversely to prices) began the reporting period near historic lows, but generally rose as inflation increased and the economy continued to strengthen. Yields of U.S. Treasuries with intermediate-term maturities, which are more sensitive to inflation, generally increased more than short-term U.S. Treasuries. The three-month U.S. Treasury yield declined modestly from 0.09% to 0.05%, while the two-year U.S. Treasury yield rose from 0.14% to 0.48%. Intermediate-term U.S. Treasury yields rose at a faster rate, with the 10-year U.S. Treasury yield increasing from 0.88% to 1.55%.

The more rapid growth of longer-dated U.S. Treasury yields meant that the yield curve (a graphical representation of U.S. Treasury yields at different maturities) steepened, particularly in the first half of the reporting period, driven by fiscal stimulus and investors’ expectations that the U.S. economy will continue to expand. However, concerns about slowing growth and the potential impact of the Delta variant flattened the yield curve late in the reporting period, partially reversing its earlier trend. As investors began to anticipate earlier interest rate increases from the Fed, shorter-term U.S. Treasury yields rose.

U.S. Treasury issuance declined slightly from record issuance in 2020 but was still greatly elevated by historical standards. The substantial issuance accompanied heavy deficit spending, in part to finance multiple additional rounds of fiscal stimulus.

About Fund Performance

Past performance is not an indication of future results. Financial markets have experienced extreme volatility and trading in many instruments has been disrupted. These circumstances may continue for an extended period of time and may continue to affect adversely the value and liquidity of each Fund’s investments. As a result, current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at iShares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. Beginning August 10, 2020, the price used to calculate market return (“Market Price”) is the closing price. Prior to August 10, 2020, Market Price was determined by using the midpoint between the highest bid and the lowest ask on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of a fund may not trade in the secondary market until after the fund’s inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike a fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

Shareholder Expenses

As a shareholder of your Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested at the beginning of the period (or from the commencement of operations if less than 6 months) and held through the end of the period, is intended to help you understand your ongoing costs (in dollars and cents) of investing in your Fund and to compare these costs with the ongoing costs of investing in other funds.

Actual Expenses – The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period.”

Hypothetical Example for Comparison Purposes – The table also provides information about hypothetical account values and hypothetical expenses based on your Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions and other fees paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

The Fund commenced operation on July 13, 2021.

2. SIGNIFICANT ACCOUNTING POLICIES

The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recorded on the ex-dividend date. Non-cash dividends, if any, are recorded on the ex-dividend date at fair value.

In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Funds. Because such gains or losses are not taxable to the Funds and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Funds’ tax year. These reclassifications have no effect on net assets or net asset value (“NAV”) per share.

Distributions: Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Funds. The character and timing of distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

Indemnifications: In the normal course of business, each Fund enters into contracts that contain a variety of representations that provide general indemnification. The Funds’ maximum exposure under these arrangements is unknown because it involves future potential claims against the Funds, which cannot be predicted with any certainty.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

Investment Valuation Policies: Each Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. Each Fund determines the fair values of its financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of the Trust (the “Board”). If a security’s market price is not readily available or does not otherwise accurately represent the fair value of the security, the security will be valued in accordance with a policy approved by the Board as reflecting fair value. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:

•

Fixed-income investments for which market quotations are readily available are generally valued using the last available bid price or current market quotations provided by independent dealers or third-party pricing services. Pricing services generally value fixed income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent


N O T E S T O F I N A N C I A L S T A T E M E N T S		61

Notes to Financial Statements (continued)

representative bids and offers), market data, credit quality information, perceived market movements, news, and other relevant information. Certain fixed-income securities, including asset-backed and mortgage related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Manager determines such method does not represent fair value.

•

Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s published NAV.

If events (e.g., market volatility, company announcement or a natural disaster) occur that are expected to materially affect the value of such investment, or in the event that application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with a policy approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Fund might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant and consistent with the principles of fair value measurement. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Fair value pricing could result in a difference between the prices used to calculate a fund’s NAV and the prices used by the fund’s underlying index, which in turn could result in a difference between the fund’s performance and the performance of the fund’s underlying index.

Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

•

Level 1 – Unadjusted price quotations in active markets/exchanges for identical assets or liabilities that each Fund has the ability to access;

•

Level 2 – Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs); and

•

Level 3 – Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, (including the Global Valuation Committee’s assumptions used in determining the fair value of financial instruments).

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Investments classified within Level 3 have significant unobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by privately held companies or funds that may not have a secondary market and/or may have a limited number of investors. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

4. SECURITIES AND OTHER INVESTMENTS

Zero-Coupon Bonds: Zero-coupon bonds are normally issued at a significant discount from face value and do not provide for periodic interest payments. These bonds may experience greater volatility in market value than other debt obligations of similar maturity which provide for regular interest payments.

Securities Lending: Each Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by an approved bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current market value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund or excess collateral is returned by the Fund, on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested in money market funds managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates is disclosed in the Schedule of Investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan, if any, are also disclosed in each Fund’s Schedule of Investments. The market value of any securities on loan and the value of any related cash collateral are disclosed in the Statements of Assets and Liabilities.

Securities lending transactions are entered into by the Funds under Master Securities Lending Agreements (each, an “MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Funds, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell or re-pledge the loaned securities, and the Funds can reinvest cash collateral


62		2 0 2 1 I S H A R E S A N N U A L R E P O R T T O S H A R E H O L D E R S

Notes to Financial Statements (continued)

received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral to the other party are extinguished, and the parties can resell or re-pledge the loaned securities or the collateral received in connection with the loaned securities in order to satisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.

As of period end, the following table is a summary of the securities on loan by counterparty which are subject to offset under an MSLA:



iShares ETF and Counterparty		Market Value of Securities on Loan		Cash Collateral Received	^(a)		Non-Cash Collateral Received		Net Amount

iBonds Dec 2022 Term Treasury
J.P. Morgan Securities LLC	$	5,709,525	$	5,709,525		$	—	$	—

iBonds Dec 2030 Term Treasury
Barclays Capital, Inc	$	600,648	$	600,648		$	—	$	—

^(a)

Collateral received in excess of the market value of securities on loan is not presented in this table. The total cash collateral received by each Fund is disclosed in the Fund’s statement of assets and liabilities.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, each Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of the securities loaned to the extent the collateral received does not cover the value of the securities loaned in the event of borrower default. Each Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by each Fund.

5. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Advisory Fees: Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of each Fund’s assets. BFA is a California corporation indirectly owned by BlackRock. Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, except (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

For its investment advisory services to each Fund, BFA is entitled to an annual investment advisory fee of 0.07%, accrued daily and paid monthly by the Funds, based on the average daily net assets of each Fund.

Expense Waivers: A fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). The total of the investment advisory fee and acquired fund fees and expenses, if any, is a fund’s total annual operating expenses. Total expenses as shown in the Statement of Operations does not include acquired fund fees and expenses.

BFA has contractually agreed to waive a portion of its investment advisory fee for each Fund through the termination date of such Fund, in an amount equal to acquired fund fees and expenses, if any, attributable to each Fund’s investments in other funds advised by BFA or its affiliates.

These amounts are included in investment advisory fees waived in the Statements of Operations. For the year ended October 31, 2021, the amounts waived in investment advisory fees pursuant to this arrangement were as follows:



iShares ETF	Amounts waived
iBonds Dec 2021 Term Treasury	$	7,655
iBonds Dec 2022 Term Treasury		690
iBonds Dec 2023 Term Treasury		616
iBonds Dec 2024 Term Treasury		136

iBonds Dec 2028 Term Treasury		138
iBonds Dec 2029 Term Treasury		225
iBonds Dec 2030 Term Treasury		6
iBonds Dec 2031 Term Treasury		2

Distributor: BlackRock Investments, LLC, an affiliate of BFA, is the distributor for each Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Funds.

Securities Lending: The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan (the “collateral investment fees”). The cash collateral is invested in a money market fund, BlackRock Cash Funds: Institutional or BlackRock Cash Funds: Treasury, managed by BFA, or its affiliates. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees


N O T E S T O F I N A N C I A L S T A T E M E N T S		63

Notes to Financial Statements (continued)

each Fund bears to an annual rate of 0.04%. The SL Agency Shares of such money market fund will not be subject to a sales load, distribution fee or service fee. The money market fund in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value redeemed or temporarily restrict redemptions for up to 10 business days during a 90 day period, in the event that the money market fund’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. Each Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to the current securities lending agreement, each Fund retains 82% of securities lending income (which excludes collateral investment fees), and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in that calendar year exceeds a specified threshold, each Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income (which excludes collateral investment fees) and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

The share of securities lending income earned by each Fund is shown as securities lending income – affiliated – net in its Statements of Operations. For the year ended October 31, 2021, the Funds paid BTC the following amounts for securities lending agent services:



iShares ETF	Fees Paid to BTC

iBonds Dec 2029 Term Treasury		386
iBonds Dec 2030 Term Treasury		165
iBonds Dec 2031 Term Treasury		1

Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is shown as dividends – affiliated in the Statements of Operations.

A fund, in order to improve its portfolio liquidity and its ability to track its underlying index, may invest in shares of other iShares funds that invest in securities in the fund’s underlying index.

6. PURCHASES AND SALES

For the year ended October 31, 2021, purchases and sales of investments, excluding short-term investments and in-kind transactions, were as follows:

7. INCOME TAX INFORMATION

Each Fund is treated as an entity separate from the Company’s other funds for federal income tax purposes. It is each Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no U.S. federal income tax provision is required.

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2021, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. As of October 31, 2021, permanent differences attributable to realized gains (losses) from in-kind redemptions were reclassified to the following accounts:



iShares ETF	Paid-in Capital			Accumulated Earnings (Loss)
iBonds Dec 2025 Term Treasury	$	48,633		$	(48,633	)
iBonds Dec 2026 Term Treasury		66,379			(66,379	)

8. PRINCIPAL RISKS

In the normal course of business, each Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject the Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. 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 Funds and their investments. Each Fund’s prospectus provides details of the risks to which the Fund is subject.

Notes to Financial Statements (continued)

BFA uses a “passive” or index approach to try to achieve each Fund’s investment objective following the securities included in its underlying index during upturns as well as downturns. BFA does not take steps to reduce market exposure or to lessen the effects of a declining market. Divergence from the underlying index and the composition of the portfolio is monitored by BFA.

The Funds may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00, which may be subject to redemption gates or liquidity fees under certain circumstances.

Market Risk: Each Fund may be exposed to prepayment risk, which is the risk that borrowers may exercise their option to prepay principal earlier than scheduled during periods of declining interest rates, which would force each Fund to reinvest in lower yielding securities. Each Fund may also be exposed to reinvestment risk, which is the risk that income from each Fund’s portfolio will decline if each Fund invests the proceeds from matured, traded or called fixed-income securities at market interest rates that are below each Fund portfolio’s current earnings rate.

An outbreak of respiratory disease caused by a novel coronavirus has developed into a global pandemic and has resulted in closing borders, quarantines, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other global health crises that may arise in the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. This pandemic may result in substantial market volatility and may adversely impact the prices and liquidity of a fund’s investments. The duration of this pandemic and its effects cannot be determined with certainty.

Counterparty Credit Risk: The Funds may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on its commitments related to unsettled or open transactions, including making timely interest and/or principal payments or otherwise honoring its obligations. The Funds manage counterparty credit risk by entering into transactions only with counterparties that the Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Funds.

Concentration Risk: A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within each Fund’s portfolio are disclosed in its Schedule of Investments.

The Funds invest a significant portion of their assets in fixed-income securities and/or use derivatives tied to the fixed-income markets. Changes in market interest rates or economic conditions may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Funds may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

LIBORTransition Risk: The United Kingdom’s Financial Conduct Authority announced a phase out of the London Interbank Offered Rate (“LIBOR”). Although many LIBOR rates will be phased out by the end of 2021, a selection of widely used USD

LIBOR rates will continue to be published through June 2023 in order to assist with the transition. The Funds may be exposed to financial instruments tied to LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The transition process away from LIBOR might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. The ultimate effect of the LIBOR transition process on the Funds is uncertain.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in shares sold in the table above.

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind transactions are reflected as a receivable or a payable in the Statements of Assets and Liabilities.

10. SUBSEQUENT EVENTS

Management’s evaluation of the impact of all subsequent events on the Funds’ financial statements was completed through the date the financial statements were available to be issued and the following items were noted:

Planned Fund Liquidation: In accordance with its prospectus and its investment objective, the iShares iBonds Dec 2021 Term Treasury ETF ceased trading after the close of business on November 30, 2021, when all of the bonds included in the Fund’s underlying index matured. Proceeds of the liquidation are currently scheduled to be sent to shareholders on December 3, 2021.

Board Review and Approval of Investment Advisory Contract


iShares iBonds Dec 2021 Term Treasury ETF, iShares iBonds Dec 2022 Term Treasury ETF, iShares iBonds Dec 2023 Term Treasury ETF, iShares iBonds Dec 2024 Term Treasury ETF, iShares iBonds Dec 2025 Term Treasury ETF, iShares iBonds Dec 2026 Term Treasury ETF, iShares iBonds Dec 2027 Term Treasury ETF, iShares iBonds Dec 2028 Term Treasury ETF, iShares iBonds Dec 2029 Term Treasury ETF, iShares iBonds Dec 2030 Term Treasury ETF (each the “Fund”)

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Board Members who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Board Members), is required annually to consider and approve the Investment Advisory Agreement between the Trust and BFA (the “Advisory Agreement”) whereby the Board and its committees (composed solely of Independent Board Members) assess BlackRock’s services to the Fund, including investment management; fund accounting; administrative and shareholder services; oversight of the Fund’s service providers; risk management and oversight; legal and compliance services; and ability to meet applicable legal and regulatory requirements. The Independent Board Members requested, and BFA provided, such information as the Independent Board Members, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Agreement. At meetings on May 7, 2021 and May 14, 2021, a committee composed of all of the Independent Board Members (the “15(c) Committee”), with independent counsel, met with management and reviewed and discussed information provided in response to initial requests of the 15(c) Committee and/or its independent counsel, and requested certain additional information, which management agreed to provide. At a meeting held on June 15-16, 2021, the Board, including the Independent Board Members, reviewed the additional information provided by management in response to these requests.

After extensive discussions and deliberations, the Board, including all of the Independent Board Members, approved the continuance of the Advisory Agreement for the Fund, based on a review of qualitative and quantitative information provided by BFA and their cumulative experience as Board Members. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Independent Board Members were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the continuance of the Advisory Agreement for the Fund, the Board, including the Independent Board Members, considered various factors, including: (i) the expenses and performance of the Fund; (ii) the nature, extent and quality of the services provided by BFA; (iii) the costs of services provided to the Fund and profits realized by BFA and its affiliates; (iv) potential economies of scale and the sharing of related benefits; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, none of which was controlling, and conclusions that formed the basis for the Board, including the Independent Board Members, to approve the continuance of the Advisory Agreement are discussed below.

Expenses and Performance of the Fund: The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, fees and expenses of another fund in which the Fund invests (if applicable), and waivers/reimbursements (if applicable) of the Fund in comparison with the same information for other ETFs (including, where applicable, funds sponsored by an “at cost” service provider), objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board noted that, due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances. The Board also noted that overall fund expenses (net of waivers and reimbursements) for the Fund were lower than the median of the overall fund expenses (net of waivers and reimbursements ) of the funds in its Peer Group, excluding iShares funds.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-year, three-year, five-year, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2020, to that of relevant comparison fund(s) for the same periods. The Board noted that the Fund seeks to track its specified underlying index and that, during the year, the Board received periodic reports on the Fund’s short- and longer-term performance in comparison with its underlying index. Such periodic comparative performance information, including additional detailed information as requested by the Board, was also considered. The Board noted that the Fund generally performed in line with its underlying index over the relevant periods.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Agreement for the coming year.

Nature, Extent and Quality of Services Provided: Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, portfolio management, product design and quality, compliance and risk management, global public policy and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Agreement for the coming year as compared with the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to support the iShares funds and their shareholders and have made significant investments into the iShares business. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made relevant officers and other employees of BFA (and its affiliates) available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies, which were provided at the May 7, 2021 meeting and throughout the year.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided to the Fund under the Advisory Agreement supported the Board’s approval of the continuance of the Advisory Agreement for the coming year.

Board Review and Approval of Investment Advisory Contract (continued)

Costs of Services Provided to the Fund and Profits Realized by BFA and its Affiliates: The Board reviewed information about the estimated profitability to BlackRock in managing the Fund, based on the fees payable to BFA and its affiliates (including fees under the Advisory Agreement), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s methodology for calculating estimated profitability of the iShares funds, noting that the 15(c) Committee and the Board had focused on the methodology and profitability presentation. The Board recognized that profitability may be affected by numerous factors, including, among other things, fee waivers by BFA, the types of funds managed, expense allocations and business mix. The Board thus recognized that calculating and comparing profitability at individual fund levels is challenging. The Board discussed with management the sources of direct and ancillary revenue, including the revenues to BTC, a BlackRock affiliate, from securities lending by the Fund. The Board also discussed BFA’s estimated profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below).

Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Agreement and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors and other information considered.

Economies of Scale: The Board reviewed information and considered the extent to which economies of scale might be realized as the assets of the Fund increase, noting that the issue of potential economies of scale had been focused on by the 15(c) Committee and the Board during their meetings and addressed by management. The 15(c) Committee and the Board received information regarding BlackRock’s historical estimated profitability, including BFA’s and its affiliates’ estimated costs in providing services. The estimated cost information distinguished, among other things, between fixed and variable costs, and showed how the level and nature of fixed and variable costs may impact the existence or size of scale benefits, with the Board recognizing that potential economies of scale are difficult to measure. The 15(c) Committee and the Board reviewed information provided by BFA regarding the sharing of scale benefits with the iShares funds through various means, including, as applicable, through relatively low fee rates established at inception, breakpoints, waivers, or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board noted that the Advisory Agreement for the Fund did not provide for breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that it would continue to assess the appropriateness of adding breakpoints in the future.

The Board concluded that this review of potential economies of scale and the sharing of related benefits, as well as the other factors considered at the meeting, supported the Board’s approval of the continuance of the Advisory Agreement for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates: The Board considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (collectively, the “Other Accounts”). The Board acknowledged BFA’s representation that the iShares funds are fundamentally different investment vehicles from the Other Accounts.

The Board received detailed information regarding how the Other Accounts generally differ from the Fund, including in terms of the types of services and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded investment vehicle, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board noted that BFA and its affiliates do not manage Other Accounts with substantially the same investment objective and strategy as the Fund and that track the same index as the Fund. The Board also acknowledged management’s assertion that, for certain iShares funds, and for client segmentation purposes, BlackRock has launched an iShares fund that may provide a similar investment exposure at a lower investment advisory fee rate.

The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund’s expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Agreement for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates: The Board reviewed other benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, both direct and indirect, including, but not limited to, payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s estimated profitability methodology), payment of advisory fees or other fees to BFA (or its affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services or other services, and BlackRock’s profile in the investment community. The Board also noted the revenue received by BFA and/or its affiliates pursuant to (i) an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds and (ii) other technology-related initiatives aimed to better support the iShares funds. The Board further noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Agreement for the coming year.

Conclusion: Based on a review of the factors described above, as well as such other factors as deemed appropriate by the Board, the Board, including all of the Independent Board Members, determined that the Fund’s investment advisory fee rate under the Advisory Agreement does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Agreement for the coming year.

Board Review and Approval of Investment Advisory Contract (continued)

iShares iBonds Dec 2031 Term Treasury ETF

(the “Fund”)

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Board Members”), is required to consider and approve the proposed Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Board Members, with advice from independent counsel, deemed reasonably necessary to evaluate the terms of the proposed Advisory Contract. At a meeting held on March 30-31, 2021, the Board, including the Independent Board Members, approved the selection of BFA as investment adviser and approved the proposed Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board also considered information previously provided by BFA, BlackRock Institutional Trust Company, N.A. (“BTC”), and BlackRock, Inc. (“BlackRock”), as applicable, at prior Board meetings. The Independent Board Members were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Board Members, considered various factors, including: (i) the expenses of the Fund; (ii) the nature, extent and quality of the services to be provided by BFA; (iii) the costs of services to be provided to the Fund and the availability of information related to profits to be realized by BFA and its affiliates; (iv) potential economies of scale and the sharing of related benefits; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, no one of which was controlling, and conclusions that formed the basis for the Board, including the Independent Board Members, to approve the Advisory Contract are discussed below.

Expenses of the Fund: The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components of the Fund in comparison with the same information for other ETFs, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

The Board also noted that the overall fund expenses (net of any waivers and reimbursements) for the Fund were lower than the median of the overall fund expenses (net of any waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level of the Fund supported the Board’s approval of the Advisory Contract.

Nature, Extent and Quality of Services: The Board reviewed the scope of services to be provided by BFA under the Advisory Contract. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time and have made significant investments into the iShares business to support the iShares funds and their shareholders. The Board considered representations by BFA, BTC, and BlackRock that the scope and quality of services to be provided to the Fund would be similar to the scope and quality of services provided to other iShares funds. The Board also considered BFA’s compliance program and its compliance record with respect to other iShares funds. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and relevant, and has provided information and made appropriate officers and other employees of BFA (and its affiliates) available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons who will be responsible for the day-to-day management of the Fund, as well as the resources that will be available to them in managing the Fund. The Board also considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies, which were provided throughout the year with respect to other iShares funds.

Based on review of this information, the Board concluded that the nature, extent and quality of services to be provided to the Fund under the Advisory Contract supported the Board’s approval of the Advisory Contract.

Costs of Services to be Provided to the Fund and Profits to be Realized by BFA and Affiliates: The Board did not consider the profitability of the Fund to BFA based on the fees payable under the Advisory Contract or revenue to be received by BFA or its affiliates in connection with services to be provided to the Fund since the proposed relationship had not yet commenced. The Board noted that it expects to receive profitability information from BFA periodically following the Fund’s launch and will thus be in a position to evaluate whether any new or additional breakpoints or other adjustments in Fund fees would be appropriate.

Economies of Scale: The Board considered information that it had previously received regarding economies of scale, efficiencies and scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that it would continue to assess the appropriateness of adding breakpoints in the future.

This consideration of potential economies of scale and the sharing of related benefits, as well as the other factors considered at the meeting, supported the Board’s approval of the Advisory Contract.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates: The Board considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (collectively, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with substantially the same investment objective and strategy as the Fund and that track the same index as the Fund.

Board Review and Approval of Investment Advisory Contract (continued)

noted that BFA previously provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the iShares funds, including in terms of the different and generally more extensive services provided to the iShares funds, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded investment vehicle, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund’s expenses borne by BFA under this arrangement.

Other Benefits to BFA and/or its Affiliates: Except as noted below, the Board did not consider the “fallout” benefits or ancillary revenue to be received by BFA and/or its affiliates in connection with the services to be provided to the Fund by BFA since the proposed relationship had not yet commenced. However, the Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board considered the potential payment of advisory fees and/or administration fees to BFA (or its affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the potential revenue to be received by BFA and/or its affiliates pursuant to an agreement that would permit a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board also considered the potential for revenue to BTC, the Fund’s securities lending agent, and its affiliates in the event of any loaning of portfolio securities of the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates (including associated commissions), will be reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the Advisory Contract.

Conclusion: Based on a review of the factors described above, as well as such other factors as deemed appropriate by the Board, the Board, including all of the Independent Board Members, determined that the Fund investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services to be rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the Advisory Contract.

^(a)

The Fund estimates that it has distributed more than its net investment income and net realized capital gains; therefore, a portion of the distribution may be a return of capital. A return of capital may occur, for example, when some or all of the shareholder’s investment in the Fund is returned to the shareholder. A return of capital does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income”. When distributions exceed total return performance, the difference will incrementally reduce the Fund’s net asset value per share.

^(b)

Rounds to less than 1%.
