The Markets in Review

Dear Shareholder,

Significant economic headwinds emerged during the 12-month reporting period ended October 31, 2022, disrupting the economic recovery and strong financial markets of 2021. The U.S. economy shrank in the first half of 2022 before returning to moderate growth in the third quarter, marking a shift to a more challenging post-reopening economic environment. Changes in consumer spending patterns and a tight labor market led to elevated inflation, which reached a 40-year high. Moreover, while the foremost effect of Russia's invasion of Ukraine has been a severe humanitarian crisis, the ongoing war continued to present challenges for both investors and policymakers.

Equity prices fell as interest rates rose, particularly weighing on relatively high-valuation growth stocks as inflation decreased the value of future cash flows and investors shifted focus to balance sheet resilience. Both large- and small-capitalization U.S. stocks fell, although declines for small-capitalization U.S. stocks were slightly steeper. Emerging market stocks and international equities from developed markets also declined significantly, pressured by rising interest rates and a strengthening U.S. dollar.

The 10-year U.S. Treasury yield rose notably during the reporting period, driving its price down, as investors reacted to higher inflation and attempted to anticipate its impact on future interest rate changes. The corporate bond market also faced inflationary headwinds, and increasing uncertainty led to higher corporate bond spreads (the difference in yield between U.S. Treasuries and similarly-dated corporate bonds).

The U.S. Federal Reserve (the "Fed"), acknowledging that inflation has been more persistent than expected, raised interest rates five times while indicating that additional rate hikes were likely. Furthermore, the Fed wound down its bond-buying programs and is accelerating the reduction of its balance sheet. As investors attempted to assess the Fed's future trajectory, the Fed's statements late in the reporting period led markets to believe that additional tightening is likely in the near term.

The pandemic's restructuring of the economy brought an ongoing mismatch between supply and demand, contributing to the current inflationary regime. While growth has slowed in 2022, we believe that taming inflation requires a more dramatic economic decline to bring demand back to a lower level that is more in line with the economy's capacity. The Fed has been raising interest rates at the fastest pace in decades, and seems set to overtighten in its effort to get inflation back to target. With this in mind, we believe the possibility of a U.S. recession in the near-term is high, and the outlook for Europe and the U.K. is also troubling. Investors should expect a period of higher volatility as markets adjust to the new economic reality and policymakers attempt to adapt to rapidly changing conditions.

In this environment, while we favor an overweight to equities in the long-term, the market's concerns over excessive rate hikes from central banks moderate our outlook. Rising input costs and a deteriorating economic backdrop in China and Europe are likely to challenge corporate earnings, so we are underweight equities overall in the near term. However, we see better opportunities in credit, where higher spreads provide income opportunities and partially compensate for inflation risk. We believe that investment-grade corporates, local-currency emerging market debt, and inflation-protected bonds (particularly in Europe) offer strong opportunities for a six- to twelve-month horizon.

Overall, our view is that investors need to think globally, position themselves to be prepared for a decarbonizing economy, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visit **blackrock.com** for further insight about investing in today's markets.

Sincerely,

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. Refer to **blackrock.com** to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Distributions paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

BlackRock Fund Advisors (the "Manager"), each Fund's investment adviser, and BlackRock Advisors, LLC (the "Administrator"), each Fund's administrator, have contractually and/or voluntarily agreed to waive and/or reimburse a portion of each Fund's expenses. Without such waiver(s) and/or reimbursement(s), each Fund's performance would have been lower. With respect to each Fund's voluntary waiver(s), if any, the Manager and the Administrator are under no obligation to waive and/or reimburse or to continue waiving and/or reimbursing its fees and such voluntary waiver(s) may be reduced or discontinued at any time. With respect to each Fund's contractual waiver(s), if any, the Manager and the Administrator are under no obligation to continue waiving and/or reimbursing its fees after the applicable termination date of such agreement. See the Notes to Financial Statements for additional information on waivers and/or reimbursements.

Disclosure of Expenses

Shareholders of each Fund may incur the following charges: (a) transactional expenses; and (b) operating expenses, including investment advisory fees, administration fees, service and distribution fees, including 12b-1 fees, acquired fund fees and expenses, and other fund expenses. The expense examples shown (which are based on a hypothetical investment of $1,000 invested at the beginning of the period and held through the end of the period) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The expense examples provide information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their Fund under the heading entitled "Expenses Paid During the Period."

The expense examples also provide information about hypothetical account values and hypothetical expenses based on a Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical examples with the 5% hypothetical examples that appear in shareholder reports of other funds.

The expenses shown in the expense examples are intended to highlight shareholders' ongoing costs only and do not reflect transactional expenses, such as sales charges, if any. Therefore, the hypothetical examples are useful in comparing ongoing expenses only and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Derivative Financial Instruments

The Funds may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. Pursuant to Rule 18f-4 of the 1940 Act, among other things, the Funds must either use derivative financial instruments with embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk. The Funds' successful use of a derivative financial instrument depends on the investment adviser's ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation a Fund can realize on an investment and/or may result in lower distributions paid to shareholders. The Funds' investments in these instruments, if any, are discussed in detail in the Notes to Financial Statements.

***1.***  ***ORGANIZATION*** 

BlackRock Funds<sup>SM</sup> (the "Trust") is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The Trust is organized as a Massachusetts business trust. The following, each of which is a series of the Trust, are referred to herein collectively as the "Funds" or individually as a "Fund":

---

The Funds, together with certain other registered investment companies advised by BlackRock Fund Advisors ("BFA" or the "Manager") or its affiliates, are included in a complex of funds referred to as the BlackRock Multi-Asset Complex. Shares of each Fund may be purchased and held only by or on behalf of mutual funds advised by BFA or its affiliates.

Investment operations for each Fund commenced on May 20, 2022.

***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 (the "trade dates"). 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 dates. Non-cash dividends, if any, are recorded on the ex-dividend dates at fair value. Upon notification from issuers, a portion of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on an accrual basis.

**Collateralization:** If required by an exchange or counterparty agreement, the Funds may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments.

**Distributions:** Distributions from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates and made at least annually. 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, a Fund enters into contracts that contain a variety of representations that provide general indemnification. A Fund's maximum exposure under these arrangements is unknown because it involves future potential claims against a Fund, which cannot be predicted with any certainty.

**Other:** Expenses directly related to a Fund are charged to that Fund. Other operating expenses shared by several funds, including other funds managed by the Manager, are prorated among those funds on the basis of relative net assets or other appropriate methods.

***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 is open for business 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. The Board of Trustees of the Trust (the "Board") has approved the designation of each Fund's Manager as the valuation designee for each Fund. Each Fund determines the fair values of its financial instruments using various independent dealers or pricing services under the Manager's policies. 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 the Manager's policies and procedures as reflecting fair value. The Manager has formed a committee (the "Valuation Committee") to develop pricing policies and procedures and to oversee the pricing function for all financial instruments, with assistance from other BlackRock pricing committees.

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

&nbsp;&nbsp;&nbsp;&nbsp;• 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 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. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Investments in open-end U.S. mutual funds (including money market funds) are valued at that day's published net
asset value ("NAV").

&nbsp;&nbsp;&nbsp;&nbsp;• Futures contracts are valued based on that day's last reported settlement or trade price on the exchange where the
contract is traded.

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 Valuation Committee in accordance with the Manager's policies and procedures as reflecting fair value ("Fair Valued Investments"). The fair valuation approaches that may be used by the 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 Valuation Committee 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 Valuation Committee deems relevant and consistent with the principles of fair value measurement.

**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:

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

&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 – Unobservable inputs based on the best information available in the circumstances, to the extent observable
inputs are not available (including the 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 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*** 

**Asset-Backed and Mortgage-Backed Securities:** Asset-backed securities are generally issued as pass-through certificates or as debt instruments. Asset-backed securities issued as pass-through certificates represent undivided fractional ownership interests in an underlying pool of assets. Asset-backed securities issued as debt instruments, which are also known as collateralized obligations, are typically issued as the debt of a special purpose entity organized solely for the purpose of owning such assets and issuing such debt. Asset-backed securities are often backed by a pool of assets representing the obligations of a number of different parties. The yield characteristics of certain asset-backed securities may differ from traditional debt securities. One such major difference is that all or a principal part of the obligations may be prepaid at any time because the underlying assets (i.e., loans) may be prepaid at any time. As a result, a decrease in interest rates in the market may result in increases in the level of prepayments as borrowers, particularly mortgagors, refinance and repay their loans. An increased prepayment rate with respect to an asset-backed security will have the effect of shortening the maturity of the security. In addition, a fund may subsequently have to reinvest the proceeds at lower interest rates. If a fund has purchased such an asset-backed security at a premium, a faster than anticipated prepayment rate could result in a loss of principal to the extent of the premium paid.

For mortgage pass-through securities (the "Mortgage Assets") there are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities that they issue. For example, mortgage-related securities guaranteed by Ginnie Mae are guaranteed as to the timely payment of principal and interest by Ginnie Mae and such guarantee is backed by the full faith and credit of the United States. However, mortgage-related securities issued by Freddie Mac and Fannie Mae, including Freddie Mac and Fannie Mae guaranteed mortgage pass-through certificates, which are solely the obligations of Freddie Mac and Fannie Mae, are not backed by or entitled to the full faith and credit of the United States, but are supported by the right of the issuer to borrow from the U.S. Treasury.

Non-agency mortgage-backed securities are securities issued by non-governmental issuers and have no direct or indirect government guarantees of payment and are subject to various risks. Non-agency mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower's ability to repay its loans.

**Capital Securities and Trust Preferred Securities:** Capital securities, including trust preferred securities, are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics. In the case of trust preferred securities, an affiliated business trust of a corporation issues these securities, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured with either a fixed or adjustable coupon that can have either a perpetual or stated maturity date. For trust preferred securities, the issuing bank or corporation pays interest to the trust, which is then distributed

to holders of these securities as a dividend. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. These securities generally are rated below that of the issuing company's senior debt securities and are freely callable at the issuer's option.

**TBA Commitments:** TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms. When entering into TBA commitments, a fund may take possession of or deliver the underlying mortgage-backed securities but can extend the settlement or roll the transaction. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases, respectively, prior to settlement date, if there are expenses or delays in connection with the TBA transactions, or if the counterparty fails to complete the transaction.

In order to better define contractual rights and to secure rights that will help a fund mitigate its counterparty risk, TBA commitments may be entered into by a fund under Master Securities Forward Transaction Agreements (each, an "MSFTA"). An MSFTA typically contains, among other things, collateral posting terms and netting provisions in the event of default and/or termination event. The collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of the collateral currently pledged by a fund and the counterparty. Cash collateral that has been pledged to cover the obligations of a fund and cash collateral received from the counterparty, if any, is reported separately in the Statements of Assets and Liabilities as cash pledged as collateral for TBA commitments or cash received as collateral for TBA commitments, respectively. Non-cash collateral pledged by a fund, if any, is noted in the Schedules of Investments. Typically, a fund is permitted to sell, re-pledge or use the collateral it receives; however, the counterparty is not permitted to do so. To the extent amounts due to a fund are not fully collateralized, contractually or otherwise, a fund bears the risk of loss from counterparty non-performance.

**Securities Lending:** Certain Funds may lend their securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Funds collateral consisting of cash, an irrevocable letter of credit issued by a 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 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 market 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 returned by the Fund, on the next business day. During the term of the loan, the Funds are entitled to all distributions made on or in respect of the loaned securities, but do 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 by the securities lending agent, BlackRock Institutional Trust Company, N.A. ("BTC"), if any, is disclosed in the Schedules 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 disclosed in the Funds' Schedules of Investments. The market value of any securities on loan and the value of any related collateral are shown separately in the Statements of Assets and Liabilities as a component of investments at value – unaffiliated and collateral on securities loaned, respectively.

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 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 Funds' securities on loan by counterparty which are subject to offset under an MSLA:

<sup>(a)</sup> Collateral received, if any, 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 Statements 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, the Funds benefit 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 on 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 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 the Funds.

***5.***  ***DERIVATIVE FINANCIAL INSTRUMENTS*** 

The Funds engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Funds and/or to manage their exposure to certain risks such as credit risk, equity risk, interest rate risk, foreign currency exchange rate risk, commodity price risk or other risks (e.g., inflation risk). Derivative financial instruments categorized by risk exposure are included in the Schedules of Investments. These contracts may be transacted on an exchange or over-the-counter ("OTC").

**Futures Contracts:** Futures contracts are purchased or sold to gain exposure to, or manage exposure to, changes in interest rates (interest rate risk) and changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).

Futures contracts are exchange-traded agreements between the Funds and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and on a specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date. Upon entering into a futures contract, the Funds are required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract's size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract. Amounts pledged, which are considered restricted, are included in cash pledged for futures contracts in the Statements of Assets and Liabilities.

Securities deposited as initial margin are designated in the Schedules of Investments and cash deposited, if any, are shown as cash pledged for futures contracts in the Statements of Assets and Liabilities. Pursuant to the contract, the Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in market value of the contract ("variation margin"). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation margin receivable (or payable) on futures contracts in the Statements of Assets and Liabilities. When the contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. The use of futures contracts involves the risk of an imperfect correlation in the movements in the price of futures contracts and interest rates, foreign currency exchange rates or underlying assets.

***6.***  ***INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES*** 

**Investment Advisory:** The Trust, on behalf of each Fund, entered into an Investment Advisory Agreement with the Manager, the Funds' investment adviser and an indirect, wholly-owned subsidiary of BlackRock, to provide investment advisory services. The Manager is responsible for the management of each Fund's portfolio and provides the personnel, facilities, equipment and certain other services necessary to the operations of each Fund.

For such services, each Fund pays the Manager a monthly fee at an annual rate equal to the following percentages of the average daily value of each Fund's net assets:

---

| | |
|:---|:---|
| *Fund Name* | *Investment* <br> *Advisory Fees*  |
|  U.S. Intermediate Credit Bond | 0.06% |

|  U.S. Long Credit Bond | 0.06 |
|  U.S. Long Government Bond | 0.05 |
|  U.S. Securitized Bond | 0.06 |

---

The Manager contractually agreed to waive each Fund's investment advisory fees through June 30, 2023. The contractual agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of each Fund. These amounts waived and/or reimbursed are included in fees waived and/or reimbursed by the Administrator/Manager in the Statements of Operations. For the period ended October 31, 2022, the amounts were as follows:

**Administration:** The Trust, on behalf of each Fund, entered into an Administration Agreement with the BlackRock Advisors, LLC (the "Administrator"), an indirect, wholly-owned subsidiary of BlackRock, to provide administrative services. For these services, the Manager receives an administration fee computed daily and payable monthly, based on a percentage of the average daily net assets of each Fund. The administration fee, which is shown as administration in the Statements of Operations, is paid at the annual rates below.

The Administrator contractually agreed to waive each Fund's administration fees through June 30, 2023. The contractual agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of each Fund. These amounts waived and/or reimbursed are included in fees waived and/or reimbursed by the Administrator/Manager in the Statements of Operations.

**Expense Waivers and Reimbursements:** The fees and expenses of the Trust's trustees who are not "interested persons" of each Fund, as defined in the 1940 Act ("Independent Trustees"), counsel to the Independent Trustees and the Funds' independent registered public accounting firm are paid directly by each Fund. The Administrator and the Manager have contractually agreed to reimburse each Fund or provide an offsetting credit to each Fund in an amount equal to these independent expenses as applicable, through June 30, 2023. The contractual agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of each Fund. The amounts waived are included in fees waived and/or reimbursed by the Administrator/Manager in the Statements of Operations. For the period ended October 31, 2022, the amounts were as follows:

**Securities Lending:** The U.S. Securities and Exchange Commission ("SEC") has issued an exemptive order which permits BTC, an affiliate of the Manager, 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, including any custodial costs. The Funds are 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 the Manager 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 the Funds bear 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 a 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 this 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 earned across the BlackRock Multi-Asset Complex in a calendar year exceeds a specified threshold, each Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year securities lending income in an amount equal to 85% of securities lending income (which excludes collateral investment fees), and this 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 the Statements of Operations. For the period ended October 31, 2022, each Fund paid BTC the following amounts for securities lending agent services:

---

| | |
|:---|:---|
| *Fund Name* | *Amounts* |
|  U.S. Intermediate Credit Bond | $18175 |
|  U.S. Intermediate Government Bond | 159766 |

|  U.S. Long Government Bond | 66617 |
|  U.S. Securitized Bond |  |

**Interfund Lending:** In accordance with an exemptive order (the "Order") from the SEC, each Fund may participate in a joint lending and borrowing facility for temporary purposes (the "Interfund Lending Program"), subject to compliance with the terms and conditions of the Order, and to the extent permitted by each Fund's investment policies and restrictions. Each Fund is currently permitted to borrow and lend under the Interfund Lending Program.

A lending BlackRock fund may lend in aggregate up to 15% of its net assets but may not lend more than 5% of its net assets to any one borrowing fund through the Interfund Lending Program. A borrowing BlackRock fund may not borrow through the Interfund Lending Program or from any other source more than 33 1/3% of its total assets (or any lower threshold provided for by the fund's investment restrictions). If a borrowing BlackRock fund's total outstanding borrowings exceed 10% of its total assets, each of its outstanding interfund loans will be subject to collateralization of at least 102% of the outstanding principal value of the loan. All interfund loans are for temporary or emergency purposes and the interest rate to be charged will be the average of the highest current overnight repurchase agreement rate available to a lending fund and the bank loan rate, as calculated according to a formula established by the Board.

During the period ended October 31, 2022, the Funds did not participate in the Interfund Lending Program.

**Trustees and Officers:** Certain trustees and/or officers of the Trust are directors and/or officers of BlackRock or its affiliates. The Funds reimburse the Manager for a portion of the compensation paid to the Trust's Chief Compliance Officer, which is included in Trustees and Officer in the Statements of Operations.

**Other Transactions:** The Funds may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment adviser, common officers, or common trustees. For the period ended October 31, 2022, the purchase and sale transactions and any net realized gains (losses) with affiliated funds in compliance with Rule 17a-7 under the 1940 Act were as follows:

***8. INCOME TAX INFORMATION***

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.

Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Fund's U.S. federal tax returns generally remains open for a period of three years after they are filed. The statutes of limitations on each Fund's state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2022, 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 NAVs per share. As of period end, permanent differences attributable to book tax difference in the basis of assets were reclassified to the following accounts:

---

|:---|:---|:---|

***9.***  ***BANK BORROWINGS*** 

The Trust, on behalf of each Fund, along with certain other funds managed by the Manager and its affiliates ("Participating Funds"), are party to a 364-day, $2.50 billion credit agreement with a group of lenders. Under this agreement, the Funds may borrow to fund shareholder redemptions. Excluding commitments designated for certain individual funds, the Participating Funds, including the Funds, can borrow up to an aggregate commitment amount of $1.75 billion at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.10% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) Overnight Bank Funding Rate ("OBFR") (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum, (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed or (c) the sum of (x) Daily Simple Secured Overnight Financing Rate ("SOFR") (but, in any event, not less than 0.00%) on the date the loan is made plus 0.10% and (y) 0.80% per annum. The agreement expires in April 2023 unless extended or renewed. These fees were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the period ended October 31, 2022, the Funds did not borrow under the credit agreement.

***10.***  ***PRINCIPAL RISKS*** 

In the normal course of business, the Funds invest in securities or other instruments and may enter into certain transactions, and such activities subject each 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 and 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 each Fund is subject.

The Manager 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. The Manager 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 the Manager.

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.

Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer's ability to make payments of principal and/or interest or otherwise affect the value of such securities. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the

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 105

------

Notes to Financial Statements (continued)

municipal market related to, taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues for the project or from the assets. Municipal securities may be less liquid than taxable bonds, and there may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities. 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. Although vaccines have been developed and approved for use by various governments, 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.

A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.

With exchange-traded futures, there is less counterparty credit risk to the Funds since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, a Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency). Additionally, credit risk exists in exchange-traded futures with respect to initial and variation margin that is held in a clearing broker's customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker's customers, potentially resulting in losses to 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.

Certain 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 decrease as interest rates rise and increase as interest rates fall. The Funds may be subject to a greater risk of rising interest rates due to the recent period of historically low interest rates. The Federal Reserve has recently begun to raise the federal funds rate as part of its efforts to address inflation. There is a risk that interest rates will continue to rise, which will likely drive down the prices of bonds and other fixed-income securities, and could negatively impact Certain Funds performance.

**Significant Shareholder Redemption Risk:** Certain shareholders may own or manage a substantial amount of fund shares and/or hold their fund investments for a limited period of time. Large redemptions of fund shares by these shareholders may force a fund to sell portfolio securities, which may negatively impact the fund's NAV, increase the fund's brokerage costs, and/or accelerate the realization of taxable income/gains and cause the fund to make additional taxable distributions to shareholders.

**LIBOR Transition Risk:** The United Kingdom's Financial Conduct Authority announced a phase out of the London Interbank Offered Rate ("LIBOR"). Although many LIBOR rates ceased to be published or no longer are representative of the underlying market they seek to measure after December 31, 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.

Disclosure of Investment Advisory Agreement

The Board of Trustees (the "Board," the members of which are referred to as "Board Members") of BlackRock Funds (the "Trust") met on February 8-9, 2022 (the "Organizational Meeting") to consider the approval of the proposed investment advisory agreement (the "Agreement") between the Trust, on behalf of iShares U.S. Intermediate Credit Bond Index Fund ("Intermediate Credit Bond Index Fund"), iShares U.S. Intermediate Government Bond Index Fund ("Intermediate Government Bond Index Fund"), iShares U.S. Long Credit Bond Index Fund ("Long Credit Bond Index Fund"), iShares U.S. Long Government Bond Index Fund ("Long Government Bond Index Fund") and iShares U.S. Securitized Bond Index Fund ("Securitized Bond Index Fund" and, together with Intermediate Credit Bond Index Fund, Intermediate Government Bond Index Fund, Long Credit Bond Index Fund and Long Government Bond Index Fund, the "Funds"), and BlackRock Fund Advisors (the "Manager"), each Fund's investment advisor. The Agreement was the same agreement that had been previously approved by the Board with respect to certain series of the Trust.

**The Approval Process** 

Consistent with the requirements of the Investment Company Act of 1940 (the "1940 Act"), the Board is required to consider the initial approval of the Agreement. The Board Members who are not "interested persons" of the Trust as defined in the 1940 Act, are considered independent Board members (the "Independent Board Members"). In connection with this deliberative process, the Board assessed, among other things, the nature, extent and quality of the services to be provided to the Funds by BlackRock, BlackRock's personnel and affiliates, including (as applicable): investment management services; accounting oversight; administrative and shareholder services; oversight of each Fund's service providers; risk management and oversight; and legal, regulatory and compliance services.

At the Organizational Meeting, the Board received and reviewed materials relating to its consideration of the proposed Agreement. The Board considered all factors it believed relevant with respect to the Funds, including, among other things: (a) the nature, extent and quality of the services to be provided by BlackRock; (b) the investment performance of the Fund as compared with a peer group of funds and to other metrics, as applicable; (c) the advisory fee and the estimated cost of the services and estimated profits to be realized by BlackRock and its affiliates from their relationship with the Fund; (d) the existence and sharing of potential economies of scale; (e) any fall-out benefits to BlackRock and its affiliates as a result of BlackRock's relationship with the Fund; (f) possible alternatives to the proposed Agreement; (g) the policies and practices of BlackRock with respect to portfolio transactions for the Fund; (h) BlackRock's portfolio compliance systems and capabilities; and (i) other factors deemed relevant by the Board Members.

In considering approval of the Agreement, the Board met with the relevant investment advisory personnel from BlackRock and considered all information it deemed reasonably necessary to evaluate the terms of the Agreement. The Board received materials in advance of the Organizational Meeting relating to its consideration of the Agreement, including (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. ("Broadridge") regarding each Fund's fees and estimated expense ratio as compared with a peer group of funds as determined by Broadridge ("Expense Peers"); (b) information regarding BlackRock's economic outlook for each Fund and its general investment outlook for the markets; (c) information regarding fees paid to service providers that are affiliates of BlackRock; and (d) information outlining the legal duties of the Board under the 1940 Act with respect to the consideration and approval of the Agreement. The Board also noted information received at prior Board meetings concerning compliance records and regulatory matters relating to BlackRock.

The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management and BlackRock's services related to the valuation and pricing of the portfolio holdings of the Funds. The Board noted the willingness of BlackRock's personnel to engage in open, candid discussions with the Board. The Board Members did not identify any particular information or any single factor as determinative, and each Board Member may have attributed different weights to the various items and factors considered.

***A. Nature, Extent and Quality of the Services to be Provided by BlackRock***

The Board, including the Independent Board Members, reviewed the nature, extent and quality of services to be provided by BlackRock, including the investment advisory services to be provided to the Funds. The Board received information concerning the investment philosophy and investment process to be used by BlackRock in managing the Funds, as well as a description of the capabilities, personnel and services of BlackRock. The Board considered the scope of the services provided by BlackRock to the Funds under the Agreement relative to services typically provided by third parties to other funds. The Board noted that the standard of care applicable under the Agreement was comparable to that found generally in investment company advisory agreements. The Board concluded that the scope of BlackRock's services to be provided to the Funds was consistent with each Fund's operational requirements, including, in addition to seeking to meet each Fund's investment objective(s), compliance with investment restrictions, tax and reporting requirements and related shareholder services.

The Board, including the Independent Board Members, also considered the quality of the administrative and other non-investment advisory services to be provided by BlackRock and its affiliates to the Funds. The Board evaluated the procedures of BlackRock designed to fulfill its fiduciary duty to the Funds with respect to possible conflicts of interest, including BlackRock's code of ethics (regulating the personal trading of BlackRock's officers and employees), the procedures by which BlackRock allocates trades among its various investment advisory clients, the integrity of the systems in place to ensure compliance with the foregoing and the record of BlackRock in these matters. The Board also noted information received at prior Board meetings concerning standards of BlackRock with respect to the execution of portfolio transactions.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and each Fund's portfolio management team; research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also considered BlackRock's overall risk management program, including the continued efforts of BlackRock and its affiliates to address cybersecurity risks and the role of BlackRock's Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRock's compensation structure with respect to each Fund's portfolio management team and BlackRock's ability to attract and retain high-quality talent and create performance incentives. The Board also considered the business reputation of BlackRock and its financial resources and concluded that BlackRock would be able to meet any reasonably foreseeable obligation under the Agreement.

In addition to investment advisory services, the Board considered the nature and quality of the administrative and other non-investment advisory services to be provided to each Fund. The Board considered that BlackRock and its affiliates will provide the Funds with certain administrative, shareholder and other services (in addition to any such services provided to the Fund by third parties) and officers and other personnel as are necessary for the operations of the Fund. In particular, BlackRock and its affiliates will

Disclosure of Investment Advisory Agreement (continued)

provide the Funds with administrative services, including, among others: (i) responsibility for disclosure documents, such as the prospectus, the summary prospectus (as applicable), the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) responsibility for periodic filings with regulators; (iv) overseeing and coordinating the activities of third-party service providers, including, among others, each Fund's custodian, fund accountant, transfer agent, and auditor; (v) organizing Board meetings and preparing the materials for such Board meetings; (vi) providing legal and compliance support; (vii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain open-end funds; and (viii) performing or managing administrative functions necessary for the operation of the Funds, such as tax reporting, expense management, fulfilling regulatory filing requirements, overseeing each Fund's distribution partners, and shareholder call center and other services. The Board reviewed the structure and duties of BlackRock's fund administration, shareholder services, and legal and compliance departments and considered BlackRock's policies and procedures for assuring compliance with applicable laws and regulations.

***B. The Investment Performance of the Funds and BlackRock***

The Board, including the Independent Board Members, previously received and considered information about BlackRock's investment performance for other funds. The Board, however, did not consider the performance history of the Funds because each Fund was newly organized and had not yet commenced operations as of the date of the Organizational Meeting.

***C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services to be Provided and Estimated Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Funds***

In connection with the initial approval of the Agreement, the Board, including the Independent Board Members, reviewed each Fund's contractual management fee rate compared with those of its Expense Peers. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared each Fund's estimated total expense ratio, as well as its estimated actual management fee rate, to those of its Expense Peers. The total expense ratio represents a fund's total net operating expenses, including any 12b-1 or non-12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual management fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. Additionally, the Board noted information received at prior Board meetings concerning the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutual funds (including mutual funds sponsored by third parties).

The Board noted that each of Intermediate Credit Bond Index Fund's, Long Credit Bond Index Fund's and Securitized Bond Index Fund's contractual management fee rate ranked in the first quartile, and that the estimated actual management fee rate and estimated total expense ratio each ranked in the first quartile relative to the pertinent Fund's Expense Peers.

The Board also noted that each of Intermediate Government Bond Index Fund's and Long Government Bond Index Fund's contractual management fee rate ranked second out of four funds, and that the estimated actual management fee rate and estimated total expense ratio each ranked first out of four funds relative to the pertinent Fund's Expense Peers.

The Board noted that for each of the Funds the Manager has agreed to contractually waive the advisory fee and the administration fee payable by each Fund and will reimburse or provide offsetting credits to each Fund for independent expenses.

Following consideration of this information, the Board, including the independent Board Members, concluded that the fees to be paid pursuant to the Agreement were fair and reasonable in light of the services provided.

As the Funds had not commenced operations as of the date of the Organizational Meeting, BlackRock was not able to provide the Board with specific information concerning the expected profits to be realized by BlackRock and its affiliates from their relationships with the Funds. BlackRock, however, will provide the Board with such information at future meetings.

***D. Economies of Scale***

The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of the Funds increase, including the existence of fee waivers and/or expense caps, as applicable, noting that any contractual fee waivers and expense caps had been approved by the Board.

***E. Other Factors Deemed Relevant by the Board Members***

The Board, including the Independent Board Members, also took into account other ancillary or "fall-out" benefits that BlackRock or its affiliates may derive from BlackRock's respective relationships with the Funds, both tangible and intangible, such as BlackRock's ability to leverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock's profile in the investment advisory community, and the engagement of BlackRock's affiliates as service providers to the Funds, including for administrative, distribution, securities lending and cash management services. The Board also considered BlackRock's overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Board also noted that, subject to applicable law, BlackRock may use and benefit from third-party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.

In connection with its consideration of the Agreement, the Board also received information regarding BlackRock's brokerage and soft dollar practices. The Board received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

The Board noted the competitive nature of the open-end fund marketplace, and that shareholders are able to redeem their Fund shares if they believe that the Fund's fees and expenses are too high or if they are dissatisfied with the performance of the Fund.

**Conclusion** 

The Board Members present at the Organizational Meeting, including the Independent Board Members, unanimously approved the Agreement between the Manager and the Trust, with respect to each Fund, for a two-year term beginning on the effective date of the Agreement. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, the Board, including the Independent Board Members, was satisfied that the terms of the Agreement were fair and reasonable and in the best interest of each Fund and its shareholders. In arriving at its decision to approve the Agreement, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination.

Additional Information

**General Information** 

Quarterly performance, semi-annual and annual reports, current net asset value and other information regarding the Funds may be found on BlackRock's website, which can be accessed at **blackrock.com**. Any reference to BlackRock's website in this report is intended to allow investors public access to information regarding the Funds and does not, and is not intended to, incorporate BlackRock's website in this report.

**Householding** 

The Funds will mail only one copy of shareholder documents, including prospectuses, annual and semi-annual reports, Rule 30e-3 notices and proxy statements, to shareholders with multiple accounts at the same address.

The following table presents fees billed by PwC that were required to be approved by the registrant's audit committee (the "Committee") for services that relate directly to the operations or financial reporting of the Fund and that are rendered on behalf of BlackRock Advisors, LLC (the "Investment Adviser" or "BlackRock") and entities controlling, controlled by, or under common control with BlackRock (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) that provide ongoing services to the Fund ("Affiliated Service Providers"):

<sup>1</sup> The nature of the services includes assurance and related services reasonably related to the performance of the audit or review of financial statements not included in Audit Fees, including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters, out-of-pocket expenses and internal control reviews not required by regulators.

<sup>2</sup> The nature of the services includes tax compliance and/or tax preparation, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews, taxable income and tax distribution calculations.

<sup>3</sup> Aggregate fees borne by BlackRock in connection with the review of compliance procedures and attestation thereto performed by PwC with respect to all of the registered closed-end funds and some of the registered open-end funds advised by BlackRock.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The Committee has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the Investment Adviser and Affiliated Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are (a) consistent with the SEC's auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimis exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Not Applicable

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (g) The aggregate non-audit fees, defined as the sum of the fees shown under "Audit-Related Fees," "Tax Fees" and "All Other Fees," paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Affiliated Service Providers were:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;**<u>Entity Name</u>** | **<u>Current Fiscal Year<br>End</u>** | **<u>Previous Fiscal Year<br>End</u>** |
| &nbsp;&nbsp;&nbsp;iShares U.S. Intermediate Credit bond Index Fund | $12000 | N/A |
| &nbsp;&nbsp;&nbsp;iShares U.S. Intermediate Government Bond Index Fund | $12000 | N/A |
| &nbsp;&nbsp;&nbsp;iShares U.S. Long Credit Bond Index Fund | $12000 | N/A |
| &nbsp;&nbsp;&nbsp;iShares U.S. Long Government Bond Index Fund | $12000 | N/A |
| &nbsp;&nbsp;&nbsp;iShares U.S. Securitized Bond Index Fund | $12000 | N/A |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and the Affiliated Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) – Not Applicable

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Not Applicable due to no such divestments during the semi-annual period covered since the previous Form N-CSR filing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) There were no changes in the registrant's internal control over financial reporting (as defined in Rule 30a-3(d) under the 1940 Act) that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
