BOND ACTIVE ETF

Investment Objective

The iShares Short Duration Bond Active ETF (the “Fund”) seeks total return in excess of the reference benchmark.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through February 28, 2030. The contractual waiver may be terminated prior to February 28, 2030 only upon written agreement of the Trust and BFA.

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

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year	3 Years	5 Years	10 Years
$26	$80	$141	$318

S-1

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 164% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in a portfolio of U.S. dollar-denominated investment-grade fixed-income securities. The Fund's reference benchmark is the Bloomberg U.S. 1-3 Year Government/Credit Bond Index, which measures the performance of U.S. dollar-denominated, government, government-related and corporate securities with remaining maturity between one and three years. The Fund primarily invests in investment-grade fixed-income securities that are rated BBB- or higher by S&P Global Ratings and/or Fitch Ratings, Inc. (“Fitch”), or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody's”), or, if unrated, determined by the Fund's management team to be of equivalent quality. The Fund primarily invests in fixed- and floating-rate securities of varying maturities, such as corporate and government bonds, agency securities, instruments of non-U.S. issuers, privately issued securities, asset-backed securities (“ABS”) and mortgage-backed securities (“MBS”), structured securities, municipal bonds, repurchase agreements, money market instruments and investment companies. The Fund invests in securities issued by financial institutions such as banks, broker-dealers and insurance companies. The Fund may enter into to-be-announced transactions (“TBA transactions”) on a regular basis with respect to the percentage of the portfolio (if any) that consists of mortgage-backed pass-through securities. BFA or its affiliates may advise the money market funds and investment companies in which the Fund may invest.

Under normal circumstances, the effective duration of the Fund’s portfolio is expected to be three years or less, as calculated by the Fund’s management team. Effective duration is a measure of the Fund’s price sensitivity to changes in yields or interest rates; however, investors should be aware that effective duration is not an exact measurement and may not reliably predict a particular security’s price sensitivity to changes in yield or interest rates.

The Fund may buy or sell options or futures on a security or an index of securities, or enter into credit default swaps and interest rate or foreign currency transactions, including swaps (collectively, commonly known as derivatives). The Fund may use derivatives to hedge its investments or to seek to enhance returns.

The Fund is an actively managed exchange-traded fund (“ETF”) that does not seek to replicate the performance of a specified index. The Fund may have a higher degree of portfolio turnover than funds that seek to replicate the performance of an index.

The Fund is not a money market fund and does not seek to maintain a stable net asset value of $1.00 per share. Please see

the Fund’s Statement of Additional Information (“SAI”) for further information.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Risk of Investing in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. Certain changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may have an adverse effect on U.S. issuers.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, pandemics or other public health issues, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

S-2

Management Risk. The Fund is subject to management risk, which is the risk that the investment process, techniques, models and/or risk analyses applied by BFA will not produce the desired results. The securities or other assets selected by BFA may result in returns that are inconsistent with the Fund’s investment objective, and the Fund may underperform the market or any relevant benchmark. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing the Fund and may adversely affect the ability of the Fund to achieve its investment objective.

Asset-Backed and Mortgage-Backed Securities Risk. ABS and MBS (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. ABS and MBS are subject to credit, interest rate, call, extension, valuation and liquidity risk. These securities, in most cases, are not backed by the full faith and credit of the U.S. government and are subject to the risk of default on the underlying asset or mortgage, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain ABS and MBS.

Asset Class Risk. The securities and other assets in the Fund’s portfolio may underperform in comparison to financial markets generally, a particular financial market, an index, or other asset classes.

Authorized Participant Concentration Risk. An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase and redemption of creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

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

Cash Transactions Risk. The Fund may effect part or all of its creations and redemptions for cash, rather than in-kind securities. As a result, the Fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, its adviser, distributor, other service providers, counterparties, or issuers of assets in which the Fund invests may cause disruptions that negatively impact the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. The Fund cannot control the cybersecurity plans and systems of its service providers, counterparties, and other third parties whose activities affect the Fund. In addition, cyber incidents may adversely impact the issuers of securities in which the Fund invests, which may cause such investments to lose value.

Derivatives Risk. The Fund’s use of derivatives (e.g., futures, forwards, swaps, options) may be riskier than other types of investments and may not have the intended effect on the Fund’s performance. Derivatives can be sensitive to changes in economic and market conditions, and they may increase the Fund’s volatility. The Fund also may experience reduced returns as a result of transaction costs and losses on derivatives positions. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivatives may create investment leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives are subject to the risk of mispricing or improper valuation, particularly if there is not a liquid secondary market for the instrument. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

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

Financial Companies Risk. Financial services companies are subject to extensive governmental regulation and intervention, which may adversely affect their profitability, the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and their size, among other things. Financial services companies also may be significantly affected by, among other things, interest rates, economic conditions, volatility in financial markets, credit rating downgrades, adverse public perception, exposure concentration and counterparty risk.

Floating Rate Securities Risk. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. Although floating rate securities

S-3

are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.

Futures Contract Risk. Futures contracts may involve risks different from, and possibly greater than, the risks associated with investing directly in the underlying assets. Swaps or other derivatives on futures contracts also may be adversely impacted by these risks. The primary risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and that of the underlying asset; (ii) resale restrictions or the lack of a liquid secondary market and the resulting inability to close a futures contract when desired; (iii) losses from unanticipated market movements, which are potentially unlimited; (iv) BFA’s inability to predict correctly the direction of the prices of futures contracts and other financial and economic factors; (v) a counterparty’s default in the performance of its obligations; (vi) the obligation to make daily cash payments to maintain the required margin for the futures contract; and (vi) the possibility that a failure to close a position may result in delivery of an illiquid commodity to the Fund.

As futures contracts approach expiration, they may be “rolled” (i.e., replaced by similar contracts with a later expiration to maintain exposure to the underlying asset), which involves additional risks. In certain market conditions, the sale price of a near-term month contract can be lower than the purchase price of a longer-term contract, resulting in a cost to “roll” the futures contract.

High Portfolio Turnover Risk. High portfolio turnover is considered by the Fund to mean turnover of greater than 100% annually. Portfolio turnover (i.e., the sale of securities or other assets and reinvestment in other securities or assets) generally involves transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other costs. In addition, the sale of securities by the Fund may result in the realization of taxable capital gains, including short-term capital gains. Higher portfolio turnover may cause the Fund to incur additional transaction costs, which have the effect of reducing the Fund’s investment return, and may result in different tax consequences for shareholders compared to a fund with lower portfolio turnover.

Illiquid Investments Risk. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce its returns because the Fund may be unable to transact at advantageous times or prices. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, it will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for Fund shares may be impacted by the liquidity in the market for the underlying securities or other assets held by the Fund, which could lead to Fund shares trading at a premium or discount to the Fund’s NAV.

Income Risk. The Fund’s income may decline when interest rates fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable

interest rates. The Fund’s income may decline because the Fund invests in lower yielding bonds, and as the bonds in its portfolio mature, are near maturity or are called, the Fund needs to purchase additional bonds.

Issuer Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders of the Fund, including an Authorized Participant, a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Municipal Securities Risk. 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 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 inability to collect revenues from such projects or assets. Certain municipal securities are issued by entities with limited taxing authority such as school districts, or are dependent on revenue from a particular sector or industry, such as the utilities sector, infrastructure sector, or transportation industry.

S-4

Not a Money Market Fund. The Fund is not a money market fund and is not subject to the strict rules that govern the quality, maturity, liquidity and other features of securities that money market funds may purchase. Under normal circumstances, the Fund’s investments may be more susceptible than a money market fund is to credit risk, interest rate risk, valuation risk and other risks relevant to the Fund’s investments. The Fund does not seek to maintain a stable net asset value of $1.00 per share.

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

Privately Issued Securities Risk. Privately issued securities are securities that have not been registered under the Securities Act of 1933, as amended (the “1933 Act”). Such securities typically are subject to legal restrictions on resale and generally are not traded in established public markets. As a result, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities, may be subject to wide fluctuations in value and may have higher transaction costs. There can be no assurance that a trading market will exist at any time for any particular privately issued security. Difficulty in selling such securities at a desirable time or price may result in a loss to the Fund.

Repurchase Agreement Risk. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund) acquires a security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by the Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price. If the seller defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security and the market value of the security declines, the Fund may lose money.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Changes in the U.S. government's financial condition or credit rating may cause the value of U.S. Treasury obligations to decline. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

Effective November 1, 2023, the Fund changed its name, investment objective and investment strategies. Performance for the periods prior to November 1, 2023 shown below is based on the investment objective and investment strategies utilized by the Fund under the name “BlackRock Short Maturity Bond ETF.” From November 1, 2023 through October 9, 2024, the Fund operated under the name “BlackRock Short Duration Bond ETF.” The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and an additional index that Fund management believes more closely reflects the investment strategy of the Fund. Fund returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

1The Fund has added this broad-based index in response to new regulatory requirements.

2The Bloomberg U.S. 1-3 Year Government/Credit Bond Index is an unmanaged index that measures the performance of government and corporate securities with one to three years remaining to maturity.

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sales of Fund shares. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Akiva Dickstein, Scott MacLellan, Amanda Liu, Sam Summers and James Mauro (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Dickstein, Mr. MacLellan, Ms. Liu, Mr. Summers and Mr. Mauro have been Portfolio Managers of the Fund since 2020, 2020, 2023, 2023 and 2021, respectively.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA, in which case, your distributions generally will be taxed when withdrawn.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in municipal securities such that the interest on each bond is exempt from U.S. federal income taxes and the federal alternative minimum tax (“AMT”). Under normal circumstances, the Fund primarily invests in U.S. dollar-denominated, investment-grade short-term fixed- and floating-rate municipal securities with remaining maturities of five years or less, such as municipal bonds, municipal notes and variable rate demand obligations, as well as money market instruments and registered investment companies. Investment-grade securities are rated BBB- or higher by S&P Global Ratings and/or Fitch Ratings, Inc. (“Fitch”), or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody's”), or, if unrated, determined by the Fund's management team to be of equivalent quality. Municipal bonds include debt obligations issued by or on behalf of a governmental entity or other qualifying issuer that pay interest that is, in the opinion of bond counsel to the issuer at the time of issuance, generally excludable from gross income for U.S. federal income tax purposes. The Fund may invest up to 20% of its net assets in municipal securities that pay interest that is subject to the federal AMT. Issuers may be states, territories and possessions of the U.S., including the District of Columbia, and their political subdivisions, agencies and instrumentalities. BFA or its affiliates may advise the money market funds and investment companies in which the Fund may invest.

Under normal circumstances, the effective duration of the Fund’s portfolio is expected to be 1.5 years or less, as calculated by the Fund’s management team. Effective duration is a measure of the Fund’s price sensitivity to changes in yields or interest rates; however, investors should be aware that effective duration is not an exact measurement and may not reliably predict a particular security’s price sensitivity to changes in yield or interest rates.

Under normal circumstances, the Fund will also seek to maintain a weighted average maturity that is less than three years. Weighted average maturity is a U.S. dollar-weighted average of the remaining term to maturity of the underlying securities in the Fund’s portfolio. The calculation of the Fund's weighted average maturity is based on the constituent securities' final maturity date or, for amortizing securities such as asset-backed and mortgage-backed securities, their weighted average life (i.e., the average length of time that each dollar of unpaid principal on the security remains outstanding).

The Fund is not a money market fund and does not seek to maintain a stable net asset value of $1.00 per share. Please see the Fund’s Statement of Additional Information (“SAI”) for further information.

Summary of Principal Risks

S-9

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that

affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

Income Risk. The Fund’s income may decline when interest rates fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable interest rates. The Fund’s income may decline because the Fund invests in lower yielding bonds, and as the bonds in its portfolio mature, are near maturity or are called, the Fund needs to purchase additional bonds.

S-10

Not a Money Market Fund. The Fund is not a money market fund and is not subject to the strict rules that govern the quality,

maturity, liquidity and other features of securities that money market funds may purchase. Under normal circumstances, the Fund’s investments may be more susceptible than a money market fund is to credit risk, interest rate risk, valuation risk and other risks relevant to the Fund’s investments. The Fund does not seek to maintain a stable net asset value of $1.00 per share.

Tax Risk. There is no guarantee that the Fund's income will be exempt from U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.”

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in a portfolio of U.S. dollar-denominated investment-grade fixed- and floating-rate debt securities that are rated BBB- or higher by S&P Global Ratings and/or Fitch Ratings, Inc. (“Fitch”), or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”), or, if unrated, determined by the Fund's management team to be of equivalent quality. Under normal circumstances, the Fund will invest primarily in fixed- and floating-rate securities maturing in three years or less. Short-term investments (generally, securities with original maturities of one year or less) held by the Fund carry a rating in one of the highest two rating categories of at least one nationally recognized statistical ratings organization (“NRSRO”) (e.g., A-2, P-2 or F2 or better by S&P Global Ratings, Moody’s or Fitch, respectively), or if such investments are unrated, are determined to be of comparable quality by the Fund's management team, at the time of investment.

The Fund may invest in corporate and U.S. and non-U.S. government bonds, agency securities, instruments of non-U.S. issuers, privately issued securities, asset-backed securities (“ABS”) and mortgage-backed securities (“MBS”), structured securities, municipal bonds, repurchase agreements, money market instruments and investment companies (including investment companies advised by BFA or its affiliates). The Fund invests a significant portion of its assets in securities issued by financial institutions, such as banks, broker-dealers and insurance companies.

Under normal circumstances, the dollar-weighted average life of the Fund’s portfolio is expected to be one year or less, as calculated by the Fund's management team. The Fund will also seek to maintain a dollar-weighted average maturity that is less than 180 days. “Dollar-weighted average life,” or “WAL,” is the weighted average of the times when principal is to be repaid. “Dollar-weighted average maturity,” or “WAM,” is calculated by taking the average length of time to maturity (fixed-rate) or the next interest rate reset (floating-rate) for each underlying instrument held by the Fund, weighted according to the relative holdings per instrument.

The Fund is not a money market fund and does not seek to maintain a stable net asset value of $1.00 per share. Please see the Fund's Statement of Additional Information (“SAI”) for further information.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

Summary of Principal Risks

S-15

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar or if there are delays or limits on the repatriation of foreign currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning. In addition, the Fund may incur costs in connection with conversions between U.S. dollars and foreign currencies.

continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. The Fund cannot control the cybersecurity plans and systems of its service providers, counterparties, and other third parties whose activities affect the Fund. In addition, cyber incidents may adversely impact the issuers of securities in which the Fund invests, which may cause such investments to lose value.

S-16

National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These

deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Fund's ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund.

S-17

the seller defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security and the market value of the security declines, the Fund may lose money.

Risk of Investing in Developed Countries. The Fund’s investment in developed country issuers will subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Additional Information About Investment Strategies – iShares Short Duration Bond Active ETF

The Fund’s investment objective is a non-fundamental policy and may be changed without shareholder approval. “Total return” used in the investment objective is a way of measuring fund performance. Total return is based on a calculation that takes into account income dividends, capital gain distributions and the increase or decrease in share price. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in a portfolio of U.S. dollar-denominated investment-grade fixed-income securities that are rated BBB- or higher by S&P Global Ratings and/or Fitch, or Baa3 or higher by Moody’s, or, if unrated, determined by the management team to be of equivalent quality. The Fund’s reference benchmark is the Bloomberg U.S. 1-3 Year Government/Credit Bond Index, which measures the performance of U.S. dollar-denominated, government, government-related and corporate securities with remaining maturity between one and three years. The Fund’s 80% investment policy may be changed by the Fund’s Board of Trustees (the “Board”) upon 60 days’ notice to shareholders.

The Fund primarily invests in fixed- and floating-rate securities of varying maturities, such as corporate and government bonds, agency securities, instruments of non-U.S. issuers, privately issued securities, ABS and MBS, structured securities, municipal bonds, money market instruments, repurchase agreements and investment companies. The Fund invests in securities issued by financial institutions such as banks, broker-dealers and insurance companies. BFA or its affiliates may advise the money market funds and investment companies in which the Fund may invest.

The Fund’s investment in instruments of non-U.S. issuers may be invested in emerging markets issuers. The Fund will invest in ABS and MBS. ABS are fixed-income securities that are backed by a pool of assets, usually loans such as installment sale contracts or credit card receivables. MBS are ABS based on a particular type of asset, a mortgage. There are a wide variety of MBS involving commercial or residential, fixed-rate or adjustable-rate mortgages and mortgages issued by banks or government agencies. Most transactions in fixed-rate mortgage pass-through securities occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement, known as TBA transactions. The Fund may enter into such contracts on a regular basis. The Fund, pending settlement of such contracts, will invest the relevant assets in high-quality, liquid short-term instruments, including shares of money market funds affiliated with BFA. Collateralized mortgage obligations (“CMOs”) are fixed-income securities that are backed by cash flows from pools of mortgages. CMOs may have multiple classes with different payment rights and protections.

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

Investment Process. The management team evaluates sectors of the fixed-income market and individual securities within these sectors to invest the Fund’s assets on an ongoing basis. The investment approach represents a collaboration between the “Portfolio Teams,” who are responsible for setting the top-down asset allocation framework for portfolio construction and security selection, and the “Sector Specialists,” who are responsible for bottom-up idea generation, including research and analysis.

The investment process is centered around formal investment strategy meetings. Following discussions with their teams, the senior members of the Sector Specialists present their teams’ views during a meeting attended by fixed-income investment professionals within BlackRock. Next, the senior members of the Portfolio and Investment Teams, along with representatives from BlackRock’s Risk & Quantitative Analysis Group, hold a meeting to discuss asset allocation, portfolio risk, and investment themes. This meeting is designed to share ideas across Portfolio Teams as each determines the appropriate interest rate risk, convexity, term structure, credit quality, liquidity bias and sector allocations for individual strategies.

The Sector Specialists then implement the Portfolio Teams’ relative value outlook with respect to security selection, timing and execution, in accordance with the Fund’s investment objective and guidelines. Sector Specialists are also responsible for trading, which BlackRock believes best leverages its market knowledge and experience. While the investment themes are discussed formally on a weekly basis, the process is dynamic, with ongoing discussion and modifications as needed.

In certain situations or market conditions, the Fund may temporarily depart from its normal investment process, provided that such departure is, in the opinion of the management team, consistent with the Fund’s investment objective and in the best interests of the Fund. For example, the Fund may hold a higher than normal proportion of its assets in cash in response to adverse market, economic or political conditions.

The management team uses an internal model for calculating duration, which may result in a different value of duration than if duration was calculated by a third party.

The Fund’s investment objective is a non-fundamental policy and may be changed without shareholder approval. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in municipal securities such that the interest on each bond is exempt from U.S. federal income taxes and the federal AMT. The Fund’s 80% investment policy may be changed by the Fund’s Board of Trustees (the “Board”) upon 60 days’ notice to shareholders.

Under normal circumstances, the Fund primarily invests in U.S. dollar-denominated, investment-grade short-term fixed- and floating-rate municipal securities with remaining maturities of five years or less such as municipal bonds, municipal notes and variable rate demand obligations, as well as money market instruments and registered investment companies. Investment-grade securities are rated BBB- or higher by S&P Global Ratings and/or Fitch, or Baa3 or higher by Moody’s, or, if unrated, determined by the management team to be of equivalent quality. Municipal bonds include debt obligations issued by or on behalf of a governmental entity or other qualifying issuer that pay interest that is, in the opinion of bond counsel to the issuer at the time of issuance, generally excludable from gross income for U.S. federal income tax purposes. The Fund may invest up to 20% of its net assets in municipal securities that pay interest that is subject to the federal AMT. Issuers may be states, territories and possessions of the U.S., including the District of Columbia, and their political subdivisions, agencies and instrumentalities. BFA or its affiliates may advise the money market funds and investment companies in which the Fund may invest.

Under normal circumstances, the Fund will also seek to maintain a weighted average maturity that is less than three years. Weighted average maturity is a U.S. dollar-weighted average of the remaining term to maturity of the underlying securities in the Fund’s portfolio. The calculation of the Fund’s weighted average maturity is based on the constituent securities’ final maturity date or, for amortizing securities such as asset-backed and mortgage-backed securities, their weighted average life (i.e., the average length of time that each dollar of unpaid principal on the security remains outstanding).

The Fund may, to a limited extent, engage in derivatives transactions that include interest rate futures.

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

Investment Process. The management team evaluates portfolio construction, municipal security selection, and trade execution on an ongoing basis. The investment approach represents a collaboration between the Liquidity Portfolio Team and Municipal Credit Research Team. The Municipal Credit Research Team provides credit oversight and research and independently rates each security in the investment universe with a BlackRock equivalent rating. The Liquidity Portfolio Team uses these credit ratings in conjunction with the following factors to manage the portfolio:

■

Credit Quality of Issuers — based on bond ratings and other factors, including economic and financial conditions.

■

Yield Analysis — takes into account factors such as the different yields available on different types of obligations and the shape of the

yield curve (longer-term obligations typically have higher yields).

■

Maturity Analysis — the weighted average maturity of the portfolio will be maintained within a desirable range as determined from time

to time. Factors considered include portfolio activity, maturity of the supply of available bonds and the shape of the yield curve.

Maturity of a debt security refers to the date upon which debt securities are due to be repaid, that is, the date when the issuer generally

must pay back the face amount of the security. The securities to be selected will have remaining maturities of up to five years,

calculated off the put dates.

The management team uses an internal model for calculating effective duration, which may result in a different value of effective duration than if it were calculated by a third party.

Under normal circumstances, the Fund invests in fixed- and floating-rate securities maturing in three years or less. Short-term investments (generally, securities with original maturities of one year or less) held by the Fund carry a rating in one of the highest two rating categories of at least one NRSRO (e.g., A-2, P-2 or F2 or better by S&P Global Ratings, Moody’s or Fitch, respectively), or if such investments are unrated, are determined to be of comparable quality by BFA, at the time of investment. The Fund’s 80% investment policy may be changed by the Fund’s Board of Trustees (the “Board”) upon 60 days’ notice to shareholders.

The Fund may, to a limited extent, engage in derivatives transactions that include futures contracts, options and swaps.

Investment Process. The cash portfolio management team participates in formal investment strategy meetings where investment professionals present their views on the various market sectors, asset allocation, portfolio risk, and other investment themes. The macro, firm-level view is a consideration in setting the investment strategy.

Decisions regarding interest rate risk, credit quality, liquidity profile and sector allocation are made by the Investment Strategy and Risk Committees. These committees build on the broader macro themes and apply them specifically to the short-term markets. The meetings are supplemented by shorter daily market updates where portfolio managers report on their specific sectors to determine relative value within the short term markets. This is a fluid process with intraday dialogue to make adjustments to portfolios when appropriate.

The collective result of these meetings is the investment strategy that liquidity portfolio managers subsequently implement. Using this method, the group is able to manage portfolios on a team basis but still leverage the individual expertise of each of its members throughout the firm.

In certain situations or market conditions, the Fund may temporarily depart from its normal investment process, provided that such departure is, in the opinion of BFA, consistent with the Fund’s investment objective and in the best interests of the Fund. For example, the Fund may hold a higher than normal proportion of its assets in cash in response to adverse market, economic or political conditions.

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

Additional Information About the Funds' Risks

Each Fund is subject to various risks, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund discloses its portfolio holdings daily at www.iShares.com. You could lose all or part of your investment in a Fund, which could underperform other investments. The table below identifies the principal and other (non-principal) risks that apply to each Fund. A Fund that invests in an underlying fund (“Underlying Fund”) also may be indirectly exposed to these risks through such investment. A description of each risk is provided after the table.

Asset-Backed and Mortgage-Backed Securities Risk. ABS and MBS (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. Although ABS generally experience less prepayment risk than residential mortgage-backed securities, MBS and ABS, like traditional fixed-income securities, are subject to credit, interest rate, call, extension, valuation and liquidity risk. Because of call and extension risk, ABS and MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain ABS and MBS.

ABS and MBS may not be backed by the full faith and credit of the U.S. government and are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.

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

In response to the financial crisis that began in 2008, the Federal Reserve System (the “Fed”) attempted to keep mortgage rates low by acting as a buyer of mortgage-backed assets. This support has ended. As a result, mortgage rates may rise and values of MBS and ABS may fall.

Asset Class Risk. The securities and other assets in a Fund’s portfolio may underperform in comparison to indexes that track, or assets that represent, other countries or geographic units, industries, markets, market segments, or asset classes. Various types of securities, other assets and indexes may experience cycles of outperformance and underperformance in comparison to financial markets generally. This divergence may be due to a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause a Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for a Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for a Fund that invests in securities issued by non-U.S. issuers or instruments with lower trading volume. Such assets often entail greater settlement and operational complexity and higher capital costs for Authorized Participants, which may limit the number of Authorized Participants that engage with the Fund.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, depend on exports from the energy, agricultural and mining sectors and, as a result, are susceptible to fluctuations in the commodity markets. These economies also increasingly

depend on their growing service industries. The Australasian economies depend on the economies of their key trading partners, which include China, Japan, South Korea, the U.S. and certain European countries. Reduced spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may have an adverse impact on some or all of the Australasian economies. Economic events in key trading countries can have a significant effect on the Australasian economies.

Other risks to Australasian countries include natural disasters that may occur in the region (e.g., droughts, earthquakes, fires, tsunamis) and national or regional security concerns (e.g., terrorism, war, strained international relations). Any such event may adversely affect the Australasian economies, financial markets or issuers of securities, causing an adverse impact on the value of a Fund’s investments.

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

Cash Management Risk. To the extent the Fund holds cash, the Fund may earn reduced income (if any) on the cash and is subject to the credit risk of the depository institution holding the cash and any fees imposed on large cash balances. If a significant amount of the Fund’s assets is invested in cash and cash equivalents, the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

Cash equivalent investments may include money market instruments. The value of money market instruments may be affected by changes in interest rates or in the credit ratings of the investments, among other things. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than U.S. government money market funds and retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

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

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

Commercial Mortgage-Backed Securities Risk. The CMBS in which the Fund invests may be issued by entities, such as banks, mortgage lenders or other institutions. These entities are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

CMBS depend on cash flows generated by underlying commercial real-estate loans, receivables or other assets, and can be significantly affected by changes in interest rates, the availability of information concerning the underlying assets and their structure, and the creditworthiness of the originators of the underlying assets.

Due to the nature of the loans they represent, CMBS are subject to a greater degree of prepayment and extension risk than many other forms of fixed-income securities. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain CMBS. Certain CMBS are issued in several classes with different levels of yield and credit protection. The Fund’s investments in CMBS with several classes may be in the lower classes that have greater risks than the higher classes, including greater interest rate, credit, prepayment and extension risks.

In addition, the value of CMBS may be adversely affected by regulatory or tax changes. CMBS issued by non-government entities may offer higher yields than those issued by government entities, but also may be subject to greater volatility than government issues. In the recent past, the market for CMBS has experienced volatility and reduced liquidity.

Concentration Risk. A Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes. A Fund with investment concentration may be more adversely affected by the underperformance of those assets, may experience greater price volatility and may be more susceptible to adverse economic, market, political or regulatory impacts on those assets compared to a fund that does not concentrate its investments.

Credit Risk. Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor its obligations.

The Fund’s portfolio may include below investment-grade bonds, which generally are subject to greater levels of credit risk than higher rated securities. There is the chance that the Fund’s holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing the Fund’s income level and share price. Debt instruments are subject to varying degrees of credit risk, depending on the issuer’s or counterparty’s financial condition and on the terms of the obligation, which may be reflected in their credit ratings.

Currency Risk. Because each Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which a Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of foreign currency, even if the foreign currency value of the Fund’s holdings in that market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, a Fund’s NAV may change quickly and without warning. In addition, a Fund may incur costs in connection with conversions between U.S. dollars and foreign currencies.

Cybersecurity Risk. A Fund and entities that interact with the Fund are susceptible to operational, information security and related cybersecurity risks, both directly and through their service providers. These entities include, but are not limited to, the Fund’s adviser, distributor, other service providers (e.g., index and benchmark providers, accountants, custodians, transfer agents and administrators), counterparties, market makers, Authorized Participants, listing exchanges, other financial market operators, and governmental authorities. Cybersecurity risks are also present for issuers of securities or other assets in which a Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s investment in such issuers to lose value. Cyber incidents can result from deliberate attacks or unintentional events. They include, but are not limited to, gaining unauthorized access to systems, misappropriating assets or sensitive information, corrupting or destroying data, and causing operational disruption. Geopolitical tensions may increase the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing.

Cybersecurity incidents may cause disruptions and impact business operations and may result in any of the following: financial losses, interference with a Fund’s ability to calculate its NAV, disclosure of confidential information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of a Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and other legal and compliance expenses. In addition, cyber incidents may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to a Fund’s functioning inaccessible, inaccurate or incomplete. A Fund may incur substantial costs in order to resolve or prevent cyber incidents.

Each Fund has established business continuity plans in the event of, and risk management systems to prevent, cyber incidents. However, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that prevention and remediation efforts will not be successful or that cyber incidents will go undetected. Furthermore, a Fund cannot control the cybersecurity plans and systems of its service providers, counterparties, and other third parties whose activities affect the Fund. A Fund and its shareholders could be negatively impacted as a result.

Derivatives Risk. A Fund’s use of derivatives (e.g., futures, forwards, swaps, options) may be riskier than other types of investments and may not have the intended effect on a Fund’s performance. Derivatives can be sensitive to changes in economic and market conditions, and they may increase a Fund’s volatility. A Fund also may experience reduced returns as a result of transaction costs and losses on derivatives positions. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivatives may create investment leverage, which could result in losses that significantly exceed a Fund’s original investment. Due to their complexity, derivatives are subject to the risk of mispricing or improper valuation. The possible lack of a liquid secondary market for derivatives and the resulting inability of a Fund to sell or otherwise close a derivatives position could expose a Fund to losses and could make derivatives more difficult for a Fund to value accurately.

Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, a Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Regulatory requirements may delay or restrict a Fund’s exercise of remedies if a derivative counterparty were to default, which could adversely impact the Fund.

The use of derivatives exposes a Fund to operational risks, such as documentation and settlement issues, systems failures, inadequate controls and human error. Derivatives also involve legal risks, including insufficient documentation, insufficient capacity or authority of a counterparty, and the legality and enforceability of a contract. Derivatives expose a Fund to derivative liquidity risks relating to potential liquidity demands for a Fund to make margin, collateral, or settlement payments.

exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of eurozone countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have affected and may in the future adversely affect the exchange rate of the euro and may significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The U.K. left the EU (“Brexit”) on January 31, 2020. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.

The national politics of countries in Europe have been unpredictable and subject to influence by disruptive political groups and ideologies, including, for example, secessionist movements. The governments of European countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe or war in the region could also impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's investments.

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

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

Financial Companies Risk. Financial services companies are subject to extensive governmental regulation and intervention, which may change frequently and may adversely affect their profitability, the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and their size, among other things. Financial services companies also may be significantly affected by, among other things, interest rates, economic conditions, credit rating downgrades, adverse public perception and exposure concentration. Increased risk-taking by financial companies may result in greater overall risk in the global financial sector. Certain events may cause an unusually high degree of volatility in financial markets and pose the risk of large losses for financial services companies.

Financial companies frequently operate with substantial financial leverage and are exposed directly to the credit risk of their borrowers and counterparties, which also may be leveraged to an unknown degree. Financial companies may have significant exposure to the same borrowers and counterparties; as a result, a borrower’s or counterparty’s inability to meet its obligations to one company may affect other financial companies with exposure to the same borrower or counterparty. This interconnectedness of risk may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financial sector generally.

Floating Rate Securities Risk. Compared to the broader U.S. Treasury note market, the issuance of floating rate obligations by the U.S. Treasury is relatively new. A deep and liquid market has not yet developed for these instruments, and the market remains relatively untested. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from floating rate securities held by the Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than fixed securities of the same maturity. The interest rate for a floating rate security resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates, such as the London Interbank Offered Rate (LIBOR) or the Secured Overnight Financing Rate (SOFR), may not accurately track market interest rates.

Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.

A Fund that rolls futures contracts is subject to additional risk. If the market for the futures contracts is in “contango,” meaning that the price of futures contracts in nearer months is lower than the price of contracts in distant months, the sale of a near-term month contract will be at a lower price than the cost of the longer-term contract, resulting in a cost to roll the contract. A Fund may also lose money in rolling a futures contract if the two contracts are trading at different prices as compared to fair value – for example, if the futures contract held by the Fund is trading at a discount to fair value and the new contract being rolled into is trading at a premium to fair value. A Fund may not roll futures contracts on a predefined schedule; instead, BFA may determine to roll to another futures contract in an attempt to generate maximum yield. There can be no guarantee that such a strategy will produce the desired results.

In addition, U.S. regulations limit the types of foreign-listed futures contracts that U.S. investors are allowed to invest in. As a result, a Fund may not be able to gain the exposure it seeks through certain non-U.S. futures contracts.

Geographic and Security Risks. Issuers in a Fund’s portfolio may be located in, or otherwise connected to, parts of the world affected by natural disasters, such as severe heat, earthquakes, tornadoes, volcanic eruptions, wildfires, droughts, floods, hurricanes and tsunamis. In addition, issuers may be impacted by security concerns with respect to a country or region, such as war and other types of conflict, terrorism, strained international relations and territorial disputes. Any of these events may adversely affect the issuers, markets and economies to which a Fund is exposed, which may adversely affect the value of the Fund.

High Portfolio Turnover Risk. The sale and purchase of securities and other assets in a Fund’s portfolio generally involve transaction costs to the Fund (e.g., brokerage commissions, dealer mark-ups). Higher portfolio turnover may cause the Fund to incur additional transaction costs, which have the effect of reducing the Fund’s investment return. In addition, greater frequency in the sale of securities or other assets may result in the realization or distribution to Fund shareholders of greater capital gains (including short-term gains) compared to a fund with less turnover. These effects of high portfolio turnover may adversely affect a Fund’s performance and could result in undesirable tax consequences for shareholders. Certain investment strategies (e.g., active management, investing in dollar rolls or to-be-announced mortgage trades) and volatile market conditions may be more likely to involve higher portfolio turnover.

Illiquid Investments Risk. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. An investment may be illiquid due to, among other things, fewer participants or less capacity to make a market in the investment, the lack of an active market for the investment, capital controls, delays or limits on repatriation of local currency, and the insolvency of local governments. To the extent that a Fund invests in securities or other assets with substantial market and/or credit risk, the Fund will tend to have increased exposure to the risks associated with illiquid investments. Illiquid investments may be harder to value, especially in changing markets.

Liquid investments may become illiquid after purchase by a Fund, particularly during periods of market turmoil. There can be no assurance that a security or other asset that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by a Fund, and any security or other asset held by a Fund may be deemed an illiquid investment pursuant to the Fund’s liquidity risk management program.

Holdings of illiquid investments may reduce a Fund’s returns because the Fund may be unable to transact at advantageous times or prices. If a Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be magnified in a rising interest rate environment or other circumstances where redemptions of Fund shares may be greater than normal. If other market participants attempt to liquidate holdings at the same time as a Fund, this will lead to an increased supply of the Fund’s underlying investments in the market and contribute to greater illiquid investments risk and downward pricing pressure. In addition, if a Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, the Fund will need to sell liquid securities to meet redemption requests, and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for a Fund’s shares may be impacted by the liquidity in the market for the underlying securities or other assets held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund's NAV.

Income Risk. The Fund’s income may decline if interest rates fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable interest rates. The Fund’s income may decline because the Fund invests in lower yielding bonds, and as bonds in its portfolio mature, are near maturity or are called, the Fund needs to purchase additional bonds.

rates may have unpredictable effects on fixed-income markets and may result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. When interest rates rise, the value of fixed-income securities or other instruments sensitive to interest rates typically decreases. Duration is a measure of how sensitive a bond is to interest rate changes. Fixed-income securities with longer durations tend to be more sensitive to interest rate changes, and their prices usually are more volatile than those of shorter-duration securities. For example, if a bond has a duration of five years and interest rates rise, the price of the bond will likely decline by a greater percentage than for a bond with a one-year duration. To the extent a Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Fund’s investments to decline significantly, which would adversely affect the Fund’s performance.

In addition, changes in prevailing interest rates, particularly sudden and significant changes, may lead to fluctuations in the value of floating-rate debt securities, because the rates for those securities typically reset only periodically. Additionally, during periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders. Under certain market conditions when interest rates are set at low levels and the market prices of portfolio securities have increased, a Fund may have a very low or even negative yield, which would cause the Fund to lose money under certain conditions.

Decreases in market-making capacity for fixed-income dealers may lead to lower trading volume, heightened volatility, wider bid-ask spreads and less transparent pricing in certain fixed-income markets.

Issuer Risk. The performance of a Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

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

To the extent these large shareholders transact in Fund shares on the secondary market, such transactions may account for a large percentage of the trading volume for Fund shares and may, therefore, have a material upward or downward effect on the market price of the shares. In addition, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, diluting its investment returns.

Management Risk. A Fund that is actively managed or that has an outcome strategy is subject to the risk that BFA’s investment process, techniques, models and/or and risk analyses in making investment decisions for the Fund will not produce the desired results. The securities or other assets selected by BFA may result in returns that are inconsistent with the Fund’s investment objective, and the Fund may underperform the market or any relevant benchmark. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing such a Fund and may also adversely affect the ability of the Fund to achieve its investment objective.

Market Risk. A Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a financial instrument or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the particular instrument or asset, or factors that affect one or more issuers, counterparties, exchanges, countries or other geographic units, markets, industries, or asset classes. Local, regional or global events such as war, acts of terrorism, pandemics or other public health issues, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on a Fund and its investments and could result in increased premiums or discounts to a Fund’s NAV. Changes in market and economic conditions generally do not have the same impact on all types of instruments and assets.

Market Trading Risk. A Fund faces numerous market trading risks, any of which may lead to its shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to the NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

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

Secondary Listing Risks. A Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. Fund shares also may be available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts. There can be no assurance that a Fund’s shares will continue to trade on any such stock exchange or in any market or that a Fund’s shares will continue to meet the requirements for exchange listing or market trading. A Fund’s shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information that is available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of a Fund may trade in the secondary market at times when the Fund does not accept orders to create or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts to NAV than might be experienced at times when the Fund accepts creation and redemption orders. Securities held by a Fund may be traded in markets that close at a different time than an exchange on which Fund shares are traded. Liquidity in those securities may be reduced after the applicable closing time. As a result, during the time when the exchange is open but after the applicable market closing, fixing or settlement time, there may be wider bid/ask spreads on the exchange and a greater premium or discount to NAV.

In stressed market conditions, the market for a Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, and an investor may be unable to sell their Fund shares.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In times of extraordinary market volatility, Fund shares may be subject to trading halts pursuant to “circuit breaker” rules of a stock exchange or market. If there is a trading halt or unanticipated closure of an exchange or market, an investor may be unable to purchase or sell Fund shares. In addition, if trading in certain securities or financial instruments is restricted, this may disrupt a Fund’s creation/redemption process, affect the price at which Fund shares trade in the secondary market, and result in a Fund being unable to trade certain securities or financial instruments. In such circumstances, a Fund may be unable to rebalance its portfolio or accurately price its portfolio holdings and may incur substantial trading losses.

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

Fund Shares May Trade at Prices Other Than NAV. Shares of a Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. A Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s portfolio holdings. The trading price of a Fund’s shares fluctuates throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund’s portfolio holdings or NAV. As a result, the trading prices of a Fund’s shares may deviate significantly from NAV during times of market volatility, significant redemption requests, or other unusual market conditions

However, because Fund shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to a Fund’s NAV are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that a Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of a Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem a Fund’s shares if there is a lack of an active market for such shares or the Fund’s underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

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

Municipal Securities Risk. Municipal securities include both general obligation bonds (bonds secured by the full faith and credit of the issuer) and limited obligation bonds (or “Revenue Bonds”). All 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. Additionally, certain municipal securities may be issued by entities with limited taxing authority, which could limit or prevent tax increases necessary to make continued payments of principal and interest.

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 municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. There is also the risk that corruption may negatively affect municipal issuers, including corruption related to a particular project from which payments on a security are derived, resulting in delays and cost overruns.

There may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities. As a result, municipal securities may be more difficult for the Fund to value accurately than the securities of public companies. Municipal securities may also be harder to buy and sell compared to taxable bonds and non-municipal securities, especially on short notice. Because the Fund invests a significant portion of its portfolio in municipal securities, the Fund’s portfolio is subject to greater exposure to illiquidity risk than a fund that invests in comparable taxable bonds or non-municipal securities.

The Fund and BFA will rely on the opinion of issuers’ bond counsel on the tax-exempt status of interest on municipal bonds. Neither the Fund nor BFA will independently review the bases for those tax opinions, which may ultimately be determined to be incorrect, potentially resulting in the Fund and its shareholders being subject to substantial tax liabilities. In addition, changes in the financial condition of an individual municipal issuer can affect the overall municipal market.

Revenue Bonds are backed by current or anticipated revenues from a specific project or specific assets and can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues from the project or the assets. Additionally, the market values of Revenue Bonds may decline in times of higher inflation to the extent that revenues are fixed income streams. In other instances, the prices that an issuer is able to charge users of its assets may be linked to inflation, whether by government regulation, contractual arrangement or other factors. Rising interest rates could result in higher costs of capital for certain issuers, which could negatively impact their ability to meet payment obligations. In this case, changes in the rate of inflation may affect the issuer’s revenues. Because many municipal securities are issued to finance projects, such as those related to education, health care, housing, transportation, utilities, and water and sewer, conditions in one or more of these sectors can affect the overall municipal market. Adverse conditions and developments affecting a particular project can result in lower revenues to an issuer of the municipal securities and, by extension, adversely affect payments of principal and interest on, or the market value of, such securities.

Additionally, certain municipal securities are issued by entities dependent on revenue from a particular sector and thus are subject to the specific risks associated with that sector.

Risk of Investing in Infrastructure-Related Municipal Securities. Entities that issue municipal securities related to infrastructure (“infrastructure issuers”) may be subject to a variety of factors that could adversely affect their capacity to make principal and interest payments, such as high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, and other factors. Such issuers may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. Infrastructure issuers can be significantly affected by government spending policies.

Leverage Risk. Infrastructure issuers can be highly indebted, which increases investment risk and other risks normally associated with debt financing, which could adversely affect such an issuer’s operations and the market value of related municipal securities in periods of rising interest rates.

Operations Risk. The failure of an infrastructure issuer to carry adequate insurance or to operate its assets appropriately could lead to significant losses. Infrastructure may be adversely affected by environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Regulatory Risk. Infrastructure projects may be subject to significant regulation by various governmental authorities and also may be affected by regulation of rates charged to customers, service interruption due to environmental, operational or other events, the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards.

Strategic Asset Risk. Infrastructure issuers may control significant strategic assets (e.g., major pipelines or highways), which are assets that have a national or regional profile, and may have monopolistic characteristics. Given their national or regional profile or irreplaceable nature, strategic assets could generate additional risk not common in other industry sectors and they may be targeted for terrorist acts or adverse political actions.

User Risk. Infrastructure issuers can be dependent upon a narrow user base. If these users do not patronize infrastructure projects as expected, significant revenues could be lost and may not be replaceable, in which case infrastructure issuers may fail to pay their obligations.

Risk of Investing in Municipal Securities Issued By School Districts. School districts rely, in part, on funding appropriations from, among others, the federal government and state governments. As a result, municipal securities issued by school districts may be adversely affected by political and economic changes at the state or federal levels, such as decreased tax or other revenues, spending reductions or changes in appropriations. Municipal securities that are issued to finance a particular school district project often depend on revenues from ad valorem taxes (i.e., property taxes) to make principal and interest payments. Investors in these securities, similar to investors in municipal securities generally, face heightened risk of loss upon insolvency of the school district issuers because there is often no ready source of funding to pay principal and interest other than the local tax base, which a bankruptcy court or administrator does not control.

Risk of Investing in Transportation Infrastructure-Related Municipal Securities. The transportation infrastructure industry may be adversely affected by economic changes, increases in fuel and other operating costs, labor relations, insurance costs, and, in many jurisdictions, the effects of regulatory changes or other government decisions. Municipal securities that are issued to finance a particular transportation project (e.g., toll roads) often depend on revenues from that project to make principal and interest payments.

Risk of Investing in Utility-Related Municipal Securities. Certain municipal securities are issued by public bodies, including state and municipal utility authorities, to, among other things, finance the operation or expansion of utility entities. Various future economic and other conditions may adversely affect utility entities, including inflation, increases in financing requirements, increases in raw material costs and other operating costs, changes in demand for services and the effects of environmental and other governmental regulations. Certain utilities are subject to specific risks. For example, gas utilities are subject to risks of supply conditions and increased competition from other providers of utility services. In addition, gas utilities are affected by gas prices, which may be magnified to the extent that a gas utility enters into long-term contracts for the purchase or sale of gas at a fixed price, since such prices may change significantly and to the disadvantage of the gas utility.

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

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. To the extent that a Fund makes investments in a limited number of countries, events in those countries will have a more significant impact on the Fund. The risks of investing in non-U.S. securities include the following, any of which may have an adverse impact on a Fund:

■

Less liquid markets, which may make valuing securities more difficult;

■

Greater market volatility;

■

Government intervention in issuers' operations or structure;

■

Government expropriation or nationalization of assets;

■

Exchange rate fluctuations and exchange controls;

■

Limitations on foreign ownership of securities;

■

Imposition of withholding or other taxes;

■

Restrictions on the repatriation of capital;

■

Higher transaction and custody costs;

■

Foreign market trading hours, different clearing and settlement procedures, and holiday schedules, which may limit a Fund's ability to

engage in portfolio transactions;

■

Less regulation of the securities and other financial markets;

■

Less availability of public information about issuers;

■

Weaker accounting, audit, disclosure and financial reporting requirements and the risk of being delisted from U.S. exchanges;

■

Difficulties in enforcing contractual obligations; and

■

Legal principals relating to corporate governance, directors’ fiduciary duties and liabilities, and shareholder rights that are less robust

than those that apply in the U.S.

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

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

Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments including the implementation of tariffs by the U.S. and the renegotiation of NAFTA in the form of the United States-Mexico-Canada Agreement (“USMCA”), which replaced NAFTA on July 1, 2020, could negatively affect North America’s economic outlook and, as a result, the value of securities held by a Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by a Fund.

Not a Money Market Fund. Each Fund is not a money market fund and is not subject to the strict rules that govern the quality, maturity, liquidity and other features of securities that money market funds may purchase. Under normal circumstances, a Fund’s investments may be more susceptible than a money market fund is to credit risk, interest rate risk, valuation risk and other risks relevant to the Fund’s investments. The Funds not seek to maintain a stable net asset value of $1.00 per share.

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

Ownership Limitations Risk. If certain aggregate and/or fund-level ownership thresholds are reached through transactions undertaken by BFA, its affiliates or a Fund, or as a result of third-party transactions or actions by an issuer or regulator, the ability of BFA and its affiliates on behalf of clients (including a Fund) to purchase or dispose of investments, exercise rights or undertake business transactions may be restricted by law, regulation or rules or otherwise impaired. The capacity of a Fund to invest in certain securities or other assets may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of a Fund’s portfolio holdings.

For example, ownership limits may apply to securities whose issuers operate in certain regulated industries or in certain international markets. Such limits also may apply where the investing entity (such as a Fund) is subject to corporate or regulatory ownership restrictions or invests in certain futures or other derivative transactions. In certain circumstances, aggregate and/or fund-level amounts invested or voted by BFA and its affiliates for client funds and accounts managed by BFA (including a Fund) may not exceed the relevant limits without the grant of a license or other regulatory or corporate approval, order, consent, relief or non-disapproval. However, there is no guarantee that permission will be granted or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. In other cases, exceeding such thresholds may cause BFA and its affiliates, a Fund or other client accounts to suffer disadvantages or business restrictions.

Ownership limitations are highly complex. It is possible that, despite BFA’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit or violate the corporate or regulatory approval, order, consent, relief or non-disapproval that was obtained.

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

Privately Issued Securities Risk. Privately issued securities are securities that have not been registered under the 1933 Act, including securities that are normally purchased pursuant to Rule 144A or Regulation S under the 1933 Act. Such securities typically are subject to legal restrictions on resale and generally are not traded in established public markets. As a result, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities, may be subject to wide fluctuations in value and may have higher transaction costs. There can be no assurance that a trading market will exist at any time for any particular privately issued security, especially under adverse market or economic conditions or if there are adverse events related to the issuer. Because there may be relatively few potential purchasers for privately issued securities, a Fund may find it more difficult to sell such securities when it may be advisable to do so, or a Fund may be able to sell such securities only at prices that are lower than if such securities were more widely held and traded. Difficulty in selling such securities at a desirable time or price may result in a loss to a Fund.

At times, it may be more difficult to determine the fair value of privately issued securities for purposes of computing a Fund’s NAV due to the absence of an active trading market. There can be no assurance that a privately issued security that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by a Fund, and its value may decline as a result, which may adversely affect the Fund.

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

significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities, or other instruments using LIBOR may disagree on transition rates or the application of transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. The Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

Risk of Investing in Developed Countries. Investment in developed country issuers will subject the Funds to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in the U.S. Investing in U.S. issuers involves legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. A decrease in imports or exports, changes in trade regulations, inflation, an economic recession, financial system stress, or political turmoil, among other risks, may have an adverse effect on the U.S. economy and the securities listed on U.S. exchanges. The U.S. is also subject to the risk of natural disasters, such as droughts, earthquakes, fires and floods. U.S. security risks include acts of terrorism, internal unrest and a deterioration in relations between the U.S. and certain countries. Any of these may adversely affect the U.S. economy, financial markets or issuers.

Governmental agencies project that the U.S. will maintain elevated public debt levels for the foreseeable future. Although elevated debt levels do not necessarily indicate or cause economic problems, the costs of servicing such debt may constrain future economic growth. Circumstances could arise that could prevent the timely payment of interest or principal on U.S. government debt, such as reaching the legislative “debt ceiling.” Such non-payment would result in substantial negative consequences for the U.S. economy and the global financial system.

Risk of Swap Agreements.Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. All swaps require posting of collateral, which may restrict the ability of the Fund to invest the assets in different ways and which involve costs to the Fund. Swaps provide customized contractual terms, which may not, in all cases, provide the hedging or other intended benefits.

Securities Lending Risk. A Fund may engage in securities lending. Securities lending involves the risk that a Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for a Fund.

Tax Risk. There is no guarantee that the Fund’s income will be exempt from U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.” BFA relies on the bond issuer’s prospectus disclosure of the opinion from its counsel as to the tax-exempt status of the investment. Neither BFA nor the Fund guarantees that this opinion is correct, and there is no assurance that the U.S. Internal Revenue Service (“IRS”) will agree with the bond issuer’s counsel’s tax opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with U.S. federal tax requirements to preserve the tax-free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued, and the security could decline significantly in value. BFA will generally seek to obtain bonds that pay interest that is exempt from U.S. federal income taxes, the federal AMT and the federal Medicare contribution tax. The interest on any money market instruments or other cash equivalents held by the Fund may be subject to the federal AMT or the federal Medicare contribution tax.

Events occurring after the date of issuance of a municipal bond or after the Fund’s acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for U.S. federal income tax, federal AMT or federal Medicare contribution tax purposes retroactively to its date of issuance. Such a determination may cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. U.S. federal or state changes in income, federal AMT or federal Medicare contribution tax rates or in the tax treatment of municipal bonds may make municipal bonds less attractive as investments and cause them to lose value. If the IRS determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable, even retroactively, and the securities could decline significantly in value.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances (e.g., reaching the legislative "debt ceiling") could arise that could prevent the timely payment of interest or principal. An actual or threatened failure of the U.S. government to pay its obligations would result in losses to a Fund holding such securities as well as substantial negative consequences for the U.S. economy and the global financial system.

Changes in the U.S. government's financial condition or credit rating may cause the value of U.S. Treasury obligations to decline. Because U.S. government debt obligations are often used as a benchmark for other borrowing arrangements, a downgrade to the credit rating of the U.S. could result in higher interest rates for a range of borrowers, cause disruptions in the international bond markets and have a substantial adverse effect on the U.S. and global economies.

A high national debt level may increase market pressures to meet government funding needs, which may drive debt costs higher and lead the government to issue additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that the U.S. government will not be able to make principal or interest payments when they are due. If market participants determine that U.S. sovereign debt levels are unsustainable, the value of the U.S. dollar could decline, thus increasing inflationary pressures and constraining the U.S. government's ability to implement effective countercyclical fiscal policy in economic downturns.

Valuation Risk. The price that a Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by a Fund also may differ from the value used by the Underlying Index (if applicable). Because non-U.S. exchanges or markets may be open on days or during time periods when a Fund does not price its shares, the value of the securities or other assets in a Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares.

In addition, for purposes of calculating a Fund’s NAV, the value of assets denominated in non-U.S. currencies (if any) is translated into U.S. dollars at the prevailing market rates. For a Fund that tracks an Underlying Index, this may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index. Authorized Participants that create or redeem Fund shares on days when a Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Portfolio Holdings Information

A description of the policies and procedures with respect to the disclosure of the Funds’ portfolio securities and other assets (as applicable) is available in the applicable Statement of Additional Information (“SAI”). Each Fund discloses its portfolio holdings daily at www.iShares.com. Fact sheets providing information about each Fund’s top holdings are posted on www.iShares.com when available and may be requested by calling 1-800-iShares (1-800-474-2737).

Management of the Funds

Investment Adviser

As investment adviser, BFA has overall responsibility for the general management and administration of the Funds. BFA provides an investment program for the Funds and manages the investment of the Funds’ assets. In seeking to achieve the Funds’ respective investment objectives, BFA uses teams of portfolio managers, investment strategists and other investment specialists and may draw upon the trading, research and expertise of its affiliates. This team approach brings together many disciplines and leverages BFA’s extensive resources.

BFA is an indirect wholly owned subsidiary of BlackRock, Inc. (“BlackRock”) and is located at 400 Howard Street, San Francisco, CA 94105. As of December 31, 2024, BFA and its affiliates provided investment advisory services for assets of approximately $11.6 trillion.

Sub-Adviser

With respect to the iShares Ultra Short-Term Bond Active ETF, BFA has entered into a sub-advisory agreement with BIL, an affiliate of BFA and an SEC-registered investment adviser and a commodity trading advisor located at Exchange Place One, 1 Semple Street, Edinburgh EH3 8BL, Scotland. BIL is primarily responsible for the execution of securities transactions outside the U.S. and Canada and may, from time to time, participate in the management of certain Fund assets, subject to the supervision and oversight of the Trust's Board of Trustees (the “Board”) and BFA. If BIL provides services relating to both portfolio management and trading, it receives from BFA an amount equal to 20% of BFA’s management fee (net of any applicable expenses). If BIL provides services related solely to trading, it receives from BFA an amount equal to 110% of the actual pre-tax costs incurred by BIL.

From time to time, an employee of BlackRock may express views regarding a particular security or other instrument, asset class, company, industry, or market sector. Such views are the views of only that individual as of the time expressed. They do not necessarily represent the views of BlackRock or any other person within the BlackRock organization. Such views may change at any time based upon market or other conditions, and BlackRock has no responsibility to update such views. You should not rely on any such views as investment advice or as an indication of trading intent on behalf of a Fund.

Fees and Expenses

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Funds), BFA is responsible for substantially all expenses of each Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, and litigation expenses and any extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust). Operating expenses paid by BFA under the Investment Advisory Agreement exclude Acquired Fund Fees and Expenses, if any.

A discussion regarding the basis for the approval by the Board of the Investment Advisory Agreement with BFA and, as applicable, the Sub-Advisory Agreement between BFA and BIL is available in the Funds' Form N-CSR filed with the SEC for the period ended October 31 and in the applicable financial statements and additional information documents posted at www.iShares.com.

For its investment advisory services to each Fund, for the fiscal year ended October 31, 2024, BFA was paid a management fee from each Fund, as a percentage of the Fund’s average daily net assets, net of any applicable waivers, at the annual rate set forth in the table below. If BFA has contractually agreed to waive a portion of its management fees for a Fund, the contractual waiver may be terminated prior to its expiration date only upon written agreement of the Trust and BFA. In addition, BFA may from time to time voluntarily waive and/or reimburse fees or expenses to reduce a Fund’s total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Fund	Management Fee
iShares Short Duration Bond Active ETF	0.25%1
iShares Short Maturity Municipal Bond Active ETF	0.25%
iShares Ultra Short-Term Bond Active ETF	0.08%

BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through February 28, 2030. The contractual waiver may be terminated prior to February 28, 2030 only upon written agreement of the Trust and BFA.

Portfolio Managers

The Portfolio Managers for each Fund are responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of their respective portfolio management teams to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of their respective teams who have more limited responsibilities.

Conflicts of Interest

The investment activities of BFA and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in managing their own accounts and other accounts, may present conflicts of interest that could disadvantage a Fund and its shareholders.

BFA and its Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and in the ordinary course of business may engage in activities in which their interests or the interests of other clients may conflict with those of a Fund. BFA and its Affiliates act, or may act, as an investor, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, trader, lender, index provider, agent and/or principal. BFA and its Affiliates may have other direct and indirect interests in securities, currencies, commodities, derivatives and other assets in which a Fund may directly or indirectly invest.

BFA and its Affiliates may engage in proprietary trading and advise accounts and other funds that have investment objectives similar to those of a Fund and/or that engage in and compete for transactions in the same or similar types of securities, currencies and other assets as are held by a Fund. This may include transactions in securities issued by other open-end and closed-end investment companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA and its Affiliates are carried out without reference to positions held directly or indirectly by a Fund. These activities may result in BFA or an Affiliate having positions in assets that are senior or junior to, or that have interests different from or adverse to, the assets held by a Fund.

A Fund may invest in securities issued by, or engage in other transactions with, entities with which an Affiliate has significant debt or equity investments or other interests. A Fund may also invest in issuances (such as debt offerings or structured notes) for which an Affiliate is compensated for providing advisory, cash management or other services. A Fund also may invest in securities of, or engage in other transactions with, entities for which an Affiliate provides or may provide research coverage or other analysis.

An Affiliate may have business relationships with, and receive compensation from, distributors, consultants or others who recommend a Fund or who engage in transactions with or for a Fund.

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

In addition, a Fund may enter into transactions in which BFA or an Affiliate or their directors, officers, employees or clients have an adverse interest. A Fund may be adversely impacted by the effects of transactions undertaken by BFA or an Affiliate or their directors, officers, employees or clients.

From time to time, BlackRock or its advisory clients (including other funds and accounts) may, subject to compliance with applicable law, purchase and hold shares of a Fund. The price, availability, liquidity, and (in some cases) expense ratio of a Fund may be impacted by purchases and sales of the Fund by BlackRock or its advisory clients.

A Fund’s activities may be limited because of regulatory restrictions applicable to BFA or an Affiliate or their policies designed to comply with such restrictions.

Under a securities lending program approved by the Board, the Funds have retained BTC, an Affiliate of BFA, to serve as their securities lending agent to the extent that they participate in the securities lending program. For these services, the securities lending agent will receive a fee from the participating Fund based on the returns earned on the Fund’s lending activities, including investment of the cash received as collateral for the loaned securities. In addition, one or more Affiliates may be among the entities to which a Fund may lend its portfolio securities under the securities lending program.

Under an ETF Services Agreement, certain Funds have retained BlackRock Investments, LLC (the “Distributor” or “BRIL”), an Affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units (“ETF Services”). BRIL will retain a portion of the standard transaction fee received from Authorized Participants on each creation or redemption order from the Authorized Participant for the ETF Services provided. BlackRock collaborated with, and received payment from, Citibank, N.A. (“Citibank”) on the design and development of the ETF Services platform. Citibank may have, or from time to time may develop, additional relationships with BlackRock or funds managed by BFA and its Affiliates.

BlackRock and its Affiliates may benefit from a Fund using a BlackRock index by creating increasing acceptance in the marketplace for such indexes. BlackRock and its Affiliates are not obligated to license an index to a Fund, and no Fund is under an obligation to use a BlackRock index. The terms of a Fund’s index licensing agreement with BlackRock or its Affiliates may not be as favorable as the terms offered to other licensees.

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

Shareholder Information

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

Buying and Selling Shares

Transactions in shares of the Funds occur in the primary market and the secondary market. Primary market transactions, known as “creations” and “redemptions,” occur only between the Funds and Authorized Participants (i.e., financial institutions that are authorized to participate in such transactions), as described in the Creations and Redemptions section below.

Fund shares are listed on U.S. national securities exchanges, where they can be bought and sold throughout the trading day at market prices, like shares of other publicly traded companies. A Fund’s shares may also be available in other secondary markets, such as on non-U.S. exchanges and through funds or structured investment vehicles similar to depositary receipts. The Funds do not impose any minimum investment for Fund shares purchased on an exchange or otherwise in the secondary market.

Buying or selling Fund shares on an exchange or other secondary market generally involves two types of costs that are common in securities transactions. First, when buying or selling Fund shares through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount; it may be a significant proportional cost if you are seeking to buy or sell small amounts of shares. Second, you may incur the cost of the “spread,” which is any difference between the bid price and the ask price for the shares. The spread varies over time based on a Fund’s trading volume and market liquidity. Generally, the spread is smaller if a Fund has high trading volume and market liquidity, and larger if a Fund has lower trading volume and market liquidity. The latter is often the case for newly launched or smaller funds. A Fund’s spread may also be impacted by the liquidity (or lack thereof) of the underlying securities or other assets held by the Fund, particularly for newly launched or smaller funds, or by instances of significant volatility of the underlying assets.

The U.S. national securities exchanges that list Fund shares are open for trading Monday through Friday and are closed on weekends and the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Investments in Investment Companies

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

Notwithstanding the foregoing, registered investment companies are permitted to invest in a Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in Rule 12d1-4 under the 1940 Act. To make such an investment in an Acquired Fund, a registered investment company must, among other things, enter into an agreement with the Trust. If an Acquired Fund invests significantly in other registered investment companies in reliance on Rule 12d1-4, an Acquiring Fund will not be permitted to rely on Rule 12d1-4 and invest in the Fund beyond the Section 12(d)(1) limits. Any investment company interested in purchasing shares of a Fund beyond the limits set forth in Section 12(d)(1) should contact BFA.

Foreign investment companies are permitted to invest in a Fund only up to the limits set forth in Section 12(d)(1), subject to any applicable SEC no-action relief.

Book Entry

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

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

Share Prices

The trading prices of a Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by various factors, such as the supply of and demand for ETF shares and the securities or other assets held by a Fund as well as other market and economic conditions.

Determination of Net Asset Value

The NAV of a Fund normally is determined once daily Monday through Friday, on each day that the New York Stock Exchange (“NYSE”) is open for trading. The NAV generally is determined as of the close of the NYSE’s regular trading hours, normally 4:00 p.m. Eastern time, based on prices at the time of closing.

Any Fund assets or liabilities that are denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers.

The NAV of a Fund is calculated by dividing the value of the Fund’s net assets (i.e., the value of its total assets, including the value of any underlying fund shares in which the Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent. The value of a Fund’s assets and liabilities is determined pursuant to BFA’s valuation policies and procedures. BFA has been designated by the Board as the valuation designee for each Fund pursuant to Rule 2a-5 under the Investment Company Act.

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

Fixed-income securities are valued using last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Funds’ approved independent third-party pricing services, each in accordance with BFA’s valuation policies and procedures. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. 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 often trade at lower prices than institutional round lots. An amortized cost method of valuation may be used with respect to debt obligations with 60 days or less remaining to maturity unless BFA determines in good faith that such method does not represent fair value.

Generally, trading in certain instruments (e.g., non-U.S. securities, money market instruments, etc.) is substantially completed each day at various times prior to the close of the NYSE’s regular trading hours. The values of such instruments used in computing a Fund’s NAV are determined as of such times.

For certain foreign assets, a third-party vendor supplies evaluated, systematic fair value pricing based upon the movement of a proprietary multi-factor model after the relevant foreign markets have closed. This systematic fair value pricing methodology is designed to correlate the prices of foreign assets in one or more non-U.S. markets following the close of the local markets to the prices that might have prevailed as of a Fund’s pricing time.

Customized exchange-traded equity options may be valued using a mathematical model that may incorporate a number of market data factors.

When market quotations are not readily available or are believed by BFA to be unreliable, BFA will fair value a Fund’s investments in accordance with its policies and procedures. Fair value represents a good faith approximation of the value of an asset or liability. It is the amount that the Fund might reasonably expect to receive from the current sale of an asset or the cost to extinguish a liability in an arm’s-length transaction.

BFA may conclude that a market quotation is not readily available or is unreliable if:

■

An asset or liability does not have a price source due to its lack of trading or other reasons;

■

A market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value;

■

An asset or liability is thinly traded;

■

There is a significant event subsequent to the most recent market quotation; or

■

The trading market on which an instrument is listed is suspended or closed and no appropriate alternative trading market is available.

A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing a Fund’s assets or liabilities, that the event is likely to cause a material change to the last exchange closing price or closing market price of one or more of the Fund’s assets or liabilities.

Valuing a Fund’s investments using fair value pricing may result in prices that differ from current market valuations and that may not be the prices at which those investments could have been sold during the period for which the particular fair values were used. For an index Fund, the use of both fair value prices and current market valuations in a particular NAV calculation 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. This could, in turn, result in a difference between the Fund’s performance and the performance of its underlying index.

Dividends and Distributions

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

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

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

Note on Tax Information. The following sections summarize some of the consequences under current U.S. federal tax law of an investment in a Fund. This information is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of Fund shares. Distributions that are attributable to interest from U.S. federal government obligations may be exempt from certain state and local tax. Consult your personal tax advisor about the potential tax consequences of an investment in Fund shares under all applicable tax laws.

Taxes

As with any investment, you should consider how your investment in shares of a Fund will be taxed, including possible tax consequences when a Fund makes distributions or when you sell Fund shares. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of a Fund. There is no guarantee that shares of a Fund will receive certain regulatory or accounting treatment.

Taxes on Fund Distributions

Shareholders in a Fund will receive information after the end of each calendar year setting forth the amount of dividends and long-term capital gains distributed to them by the Fund during the prior year, if any. Likewise, the amount of tax-exempt income, if any, that a Fund distributes will be reported. Such income must be reported on the shareholder’s U.S. federal income tax return.

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

Capital Gains. Distributions from a Fund’s net investment income (other than qualified dividend income or from net tax-exempt income, if any), including distributions of income from securities lending and distributions out of a Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by a Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Long-term capital gains and qualified dividend income are generally eligible for taxation at preferential rates for non-corporate shareholders. However, different preferential rates may apply depending on the type of capital gains, such as Fund distributions of certain amounts received from real estate investment trusts (“REITs”), if any.

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

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

Dividends received by a Fund from a RIC, if any, generally are qualified dividend income only to the extent that such dividend distributions are made out of qualified dividend income received by such RIC. Additionally, it is expected that dividends received by a Fund from a REIT, if any, and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. However, for tax years beginning after December 31, 2017 and before January 1, 2026, a Fund may report dividends eligible for a 20% “qualified business income” deduction for non-corporate U.S. shareholders to the extent that the Fund’s income is derived from ordinary REIT dividends, reduced by allocable Fund expenses.

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

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

Substitute dividends received by a Fund with respect to dividends paid on securities lent out, if any, will not be qualified dividend income.

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

Alternative Minimum Tax. The AMT is a separate U.S. federal tax system that operates in parallel to the regular federal income tax system but eliminates many deductions and exclusions. The AMT has different tax rates and treats as taxable certain types of income that are nontaxable for regular income tax purposes, such as the interest on certain “private activity” municipal bonds. If a taxpayer’s overall AMT liability is higher than regular income tax liability, then the taxpayer owes the regular income tax liability plus the difference between the AMT liability and the regular income tax liability.

Tax Exempt Dividends

For each Fund listed below, dividends paid by the Fund that are properly reported as tax-exempt interest dividends will not be subject to regular U.S. federal income tax. Each Fund intends to invest its assets in a manner such that dividend distributions to its shareholders generally will be exempt from U.S. federal income taxation, including the federal AMT, except for the iShares Short Maturity Municipal Bond Active ETF. Dividends paid by a Fund will be exempt from U.S. federal income tax (though not necessarily exempt from state and local taxation) to the extent of the Fund’s tax-exempt interest income as long as 50% or more of the value of the Fund’s assets at the end of each quarter is invested in state, municipal and other bonds whose interest is excluded from gross income for U.S. federal income tax purposes and as long as the Fund properly reports such dividends as tax-exempt interest dividends.

Exempt interest dividends from interest earned on the municipal securities of a state or its political subdivisions may be exempt from income tax in that state. However, income from the municipal securities of one state generally will not qualify for tax-free treatment in other states.

iShares Short Maturity Municipal Bond Active ETF

Original Issue Discount and Inflation-Related Adjustments

Accruals of “original issue discount” on bonds that a Fund acquires at a discount and adjustments for inflation to the principal amount of an inflation-protected U.S. Treasury bond held by a Fund may be included for tax purposes in the Fund’s gross income, even though no cash attributable to such gross income has at that point been received by the Fund. In such event, the Fund may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Fund may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Fund and additional capital gains distributions to Fund shareholders. In addition, any deflation-related adjustments during the taxable year to an inflation-indexed bond held by a Fund may cause amounts distributed in the taxable year as income to be characterized as a return of capital.

Market Discount Bonds

Any market discount recognized on a bond, including a tax-exempt interest bond, is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or adjusted issue price if issued with original issue discount. To the extent that a Fund does not include the market discount in income as it accrues, gains on the Fund’s disposition of such an obligation will be treated as ordinary income rather than capital gains to the extent of the accrued market discount.

Derivatives and Other Complex Instruments

A Fund may invest in derivatives and other complex instruments, and such investments may be subject to special and complicated rules. These rules could affect whether gains and losses recognized by a Fund are treated as ordinary income or capital gains, accelerate the recognition of income to a Fund or defer a Fund’s ability to recognize losses. In addition, these rules may affect the amount, timing or character of income distributed to you by a Fund. You should consult your personal tax advisor regarding the application of these rules.

Non-U.S. Income Taxes

Dividends, interest and capital gains (if any) earned by a Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If, at the close of a year, more than 50% of a Fund’s total assets consist of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes, including withholding taxes, paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income or, subject to certain limitations, a credit in calculating your U.S. federal income tax. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If a Fund does not pass through non-U.S. taxes, the Fund will be entitled to claim a deduction for certain foreign taxes that it incurs.

Under certain circumstances, if a Fund receives a refund of foreign taxes paid with respect to a prior year, the value of Fund shares could be affected or any foreign tax credits or deductions passed through to shareholders with respect to the Fund’s foreign taxes for the current year could be reduced.

If, at the close of the year, more than 50% of a Fund’s total assets consist of stocks or securities issued by non-U.S. issuers, including depositary receipts (no matter where traded) of non-U.S. companies, or, at the close of each quarter, more than 50% of a Fund’s total assets consist of shares of an Underlying Fund, the Fund may “pass-through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or, if its assets meet these requirements, the Underlying Fund.

For purposes of foreign tax credits for U.S. shareholders of a Fund, foreign capital gains taxes may not produce associated foreign source income, limiting the availability of such credits for U.S. persons.

Non-U.S. Shareholders

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

Separately, a 30% withholding tax may be imposed on Fund distributions (if any) paid to certain foreign entities, unless such entities comply, or are deemed compliant, with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts.

Backup Withholding

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

Securities Lending

If your shares of a Fund are loaned out pursuant to a securities lending arrangement, you may lose the ability to treat Fund dividends that are paid while the shares are held by the borrower as qualified dividend income, and you may lose the ability to use non-U.S. tax credits passed through by the Fund.

Fund of Funds

If a Fund invests in an Underlying Fund, short-term capital gains earned by the Underlying Fund, if any, will be ordinary income when distributed to the Fund and will not be offset by the Fund’s capital losses. To the extent such Fund is expected to invest in an Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Capital loss carryforwards of the Underlying Fund, if any, will not offset net capital gains of the Fund.

Taxes on the Sale of Exchange-Listed Fund Shares

Any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term capital gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares that have been held for one year or less is generally treated as a short-term capital gain or loss. However, any capital loss on a sale of Fund shares held for six months or less is treated as a long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from

sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

Creations and Redemptions

Prior to being traded in the secondary market, Fund shares are “created” at NAV by Authorized Participants (i.e., market makers, large investors and other financial institutions) in block-size Creation Units or multiples thereof. Fund shares are created or redeemed only in Creation Units, and only Authorized Participants may create or redeem Creation Units with the Funds.

Each Authorized Participant is a member or participant of a clearing agency registered with the SEC and has entered into a written agreement with the Funds’ Distributor, an affiliate of BFA. The agreement allows the Authorized Participant to place orders for the purchase and redemption of Creation Units. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Funds. Creation transactions are subject to acceptance by the Distributor and the relevant Fund.

Generally, there are three transaction methods for creating and redeeming Fund shares: in-kind securities (“in-kind”), partial cash and all cash.

In-Kind. In a creation transaction, an Authorized Participant deposits into a Fund a “creation basket,” which is a portfolio of securities or other assets designated by the Fund, as well as a cash amount. The Authorized Participant receives a specified number of Creation Units in return. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a “redemption basket,” which is a portfolio of securities or other assets designated by the Fund, as well as a cash amount.

Partial Cash. In a creation transaction, an Authorized Participant deposits into a Fund a creation basket and a cash amount, including cash that replaces a security or other asset in the creation basket, in exchange for Creation Units. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a redemption basket and a cash amount, including cash that replaces a security or other asset in the redemption basket.

All Cash. In a creation transaction, an Authorized Participant deposits into a Fund an amount of cash specified by the Fund in exchange for Creation Units. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a specified amount of cash.

The creation and redemption baskets for a Fund may differ in composition, and certain iShares ETFs accept “custom baskets.” More information about custom baskets is provided in the Funds’ SAI.

Each Fund generally engages in creation and redemption transactions according to the method indicated in the table below. In certain circumstances, however, a Fund may use another transaction method (e.g., an in-kind Fund may transact partially or fully in cash).

Fund	In-Kind	Partial	All Cash
iShares Short Duration Bond Active ETF			✓
iShares Short Maturity Municipal Bond Active ETF			✓
iShares Ultra Short-Term Bond Active ETF			✓

The prices at which creations and redemptions occur are based on the next calculation of a Fund’s NAV after a creation or redemption order is tendered in an acceptable form under the Authorized Participant agreement. In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, creation and redemption orders may not be executed according to a Fund’s instructions or may not be executed at all.

Additional information about the creation and redemption of Creation Units (including the cut-off times for the receipt of creation and redemption orders) is included in the Funds’ SAI.

The Funds do not impose restrictions on the frequency of purchases and redemptions of Fund shares directly with a Fund. The Board determined not to adopt policies and procedures designed to prevent or monitor for frequent purchases and redemptions of Fund shares because each Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, with a deadline for placing cash-related transactions no later than the close of the primary markets for the Fund’s portfolio securities. However, the Funds have taken certain measures (e.g., imposing transaction fees on purchases and redemptions of Creation Units and reserving the right to reject purchases of Creation Units under certain circumstances) to minimize the potential consequences of frequent cash purchases and redemptions by Authorized Participants, such as increased tracking error, disruption of portfolio management, dilution to the Funds, and/or increased transaction costs. Further, the vast majority of trading in Fund shares occurs on the secondary market, which does not involve the Funds directly, and such trading is unlikely to cause many of the harmful effects of frequent cash purchases or redemptions of Fund shares.

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

Because Fund shares may be created and issued on an ongoing basis, at any point during the life of a Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

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

Householding

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

Distribution

The Distributor or its agent distributes Creation Units for the Funds on an agency basis. The Distributor does not maintain a secondary market in shares of the Funds. The Distributor has no role in determining the policies of the Funds or the securities or other assets (as applicable) that are purchased or sold by the Funds. The Distributor’s principal address is 50 Hudson Yards, New York, NY 10001.

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

Financial Highlights

The financial highlights table for each Fund is intended to help you understand the Fund’s financial performance for the past five fiscal years or, if shorter, the period since the Fund’s inception. Certain information reflects financial results for a single Fund share. The total return information represents the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report, along with each Fund’s financial statements, is included in each Fund’s Form N-CSR (available upon request).

iSHARES® BLOOMBERG ROLL SELECT COMMODITY STRATEGY ETF

Ticker: CMDYStock Exchange: NYSE Arca

Investment Objective

The iShares Bloomberg Roll Select Commodity Strategy ETF (the “Fund”) seeks to track the investment results of an index composed of a broad range of commodity exposures with enhanced roll selection, on a total return basis.

Fees and Expenses

The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through February 28, 2026. The contractual waiver may be terminated prior to February 28, 2026 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it, directly or indirectly through a subsidiary, buys and sells securities or other assets (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the Bloomberg Roll Select Commodity Total Return Index (the “Underlying Index”), which measures the performance of 24 futures contracts across 22 physical agricultural, energy, precious metals and industrial metals commodities. The Underlying Index, which is rebalanced annually, provides broad-based exposure to commodities as an asset class by using liquidity factors and sector caps to avoid over-concentration in any single commodity or commodity sector.

The Fund, through its Subsidiary (as defined below), invests in financial instruments providing exposure to commodities and not in the physical commodities themselves. In seeking to achieve its investment objective, the Fund primarily invests in exchange-traded futures contracts (“Index Futures”) on the Underlying Index and is expected to roll out of existing positions in Index Futures and establish new positions in Index Futures on an ongoing basis. Index Futures subsequently acquired by the Fund may have terms that differ from those of the Index Futures it currently holds, and the purchase and sale of these Index Futures may incur transaction fees. Although the Fund may hold the same futures contracts under the same futures rolling schedule as those included in the Underlying Index, the Fund is not obligated to invest in any futures contracts included in the Underlying Index.

The Fund may also invest in exchange-traded commodity futures contracts similar to those found in the Underlying Index, swaps and options on futures that correlate to the investment returns of commodities without investing directly in physical commodities, and over-the-counter commodity-linked instruments such as commodity-linked notes, swaps and forward contracts (collectively with Index Futures, “Commodity Investments”). Investing in Commodity Investments may have a leveraging effect on the Fund.

The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in Commodity Investments through a cash management strategy consisting of investments in cash and cash equivalents, short-term government obligations and short-term investment grade fixed-income securities (collectively, “Fixed-Income Investments”). The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s investments in derivatives on a day-to-day basis.

futures contract is less than the price of the expiring contract, then the market for the commodity is said to be in “backwardation.” In these markets, roll returns are positive, which is referred to as “positive carry.” The term “contango” is used to describe a market in which the price for a new futures contract is more than the price of the expiring contract. In these markets, roll returns are negative, which is referred to as “negative carry.” The Underlying Index seeks to employ a positive carry strategy that emphasizes commodities and futures contract months with the greatest degree of backwardation and lowest degree of contango, resulting in net gains through positive roll returns.

As of October 31, 2024, the Underlying Index had 24 components.

The Fund gains exposure to Commodity Investments by investing through a wholly owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and, unless otherwise noted in this Prospectus, is not subject to the investor protections of the 1940 Act. The Subsidiary invests solely in Commodity Investments and cash and cash equivalents.

In compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity Investments held in the Subsidiary are intended to provide the Fund with exposure to broad commodities consistent with current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity Investments.

The remainder of the Fund’s assets are invested directly by the Fund, primarily in Fixed-Income Investments, including repurchase agreements, money market instruments, U.S. government and agency securities, Treasury inflation-protected securities, sovereign debt obligations on non-U.S. countries and investment-grade corporate bonds.

BFA uses an indexing approach to try to achieve the Fund’s investment objective. The Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor selection of securities and/or other instruments. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively has an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not

S-2

hold all of the securities and/or other instruments in the Underlying Index.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject registered investment companies and their advisers to regulation by the CFTC if a registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if a registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of such instruments above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”). The Subsidiary is also deemed a commodity pool. BFA is considered a commodity pool operator (“CPO”) with respect to the Fund and the Subsidiary and is subject to regulation by the CFTC and the National Futures Association (“NFA”).

The Underlying Index is sponsored by Bloomberg Index Services Limited (the “Index Provider” or “Bloomberg”), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Subsidiary) any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

margin with respect to its holdings in derivatives. Each of these factors and events could have a significant negative impact on the Fund.

Carry Strategy Risk. The futures market for a commodity in which the price for a new futures contract is less than the price of an expiring contract, known as a market trading in a state of “backwardation,” may not continue to trade with the same degree of backwardation or with the resulting returns. To the extent that a commodity futures market is not trading in a state of backwardation (or is trading in such a state, but to a lesser degree), the Fund’s cost to maintain exposure to the commodity may increase, the positive carry strategy may prove unsuccessful, and the investment performance of the Fund may suffer.

S-3

conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to financial markets generally, a particular financial market, another index, or other asset classes.

Cash Management Risk. If a significant amount of the Fund’s assets is invested in cash and cash equivalents, the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

Commodity Market Disruption Risk. The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation, intervention and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices that may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be executed beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. The CFTC and the U.S. commodities exchanges are also authorized to take other actions in the event of a market emergency, including, for example, the imposition of higher margin requirements and the suspension of trading. Any of those actions, if taken, could adversely affect the returns of the Fund.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Commodity Risk. The Fund has substantial exposure to commodities. The Fund invests in instruments that are susceptible to fluctuations in certain commodity markets and to price changes due to trade relations, including the imposition of tariffs by the U.S. and other countries. Any negative changes in commodity markets that may be due to changes in supply and demand for commodities, market events, war, regulatory developments, political instability, other catastrophic events, or other factors that the Fund cannot control could have an adverse impact on the Commodity Investments in which the Fund invests.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, its adviser, distributor, Index Provider, other service providers, counterparties, or issuers of assets in which the Fund invests may cause disruptions that negatively impact the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. The Fund cannot control the cybersecurity plans and systems of its service providers, counterparties, and other third parties whose activities affect the Fund. In addition, cyber incidents may adversely impact the issuers of securities in which the Fund invests, which may cause such investments to lose value.

and market conditions, and they may increase the Fund’s volatility. The Fund also may experience reduced returns as a result of transaction costs and losses on derivatives positions. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivatives may create investment leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives are subject to the risk of mispricing or improper valuation, particularly if there is not a liquid secondary market for the instrument. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

Energy Sector Risk. The performance of energy-related commodities is generally cyclical and highly dependent on energy prices. The market value of energy-related commodities may decline for many reasons, including, among others, changes in energy prices, energy supply and demand, global political changes, terrorism, natural disasters and other catastrophes; government regulations, taxation policies and energy conservation efforts. The energy sector has recently experienced increased volatility. In particular, significant market volatility in the crude oil markets as well as the oil futures markets, which resulted in the market price of the front month WTI crude oil futures contract falling below zero for a period of time.

Income Risk. The Fund’s income may decline when yields fall. This decline can occur because the Fund may subsequently invest in lower-yielding Fixed-Income Investments, as Fixed-Income Investments in its portfolio mature, are near maturity or are called, or the Fund otherwise needs to purchase additional bonds.

certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the Underlying Index and may hold securities or other assets not included in the Underlying Index, it is subject to the risk that the investment strategy of BFA may not produce the intended results. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.

each commodity. Increased competition and changes in consumer tastes and spending can also influence the demand for agricultural and livestock products, affecting the price of such commodities and the performance of the Fund.

Risk of Investing in Gold. The Fund has exposure to gold through its investments in total return swaps on the Underlying Index. Thus, the Fund’s portfolio may be adversely affected by changes or trends in the price of gold. The price of gold and of gold-related instruments historically has been volatile, which may adversely affect the value of total return swaps on the Underlying Index. Governments, central banks, or other larger holders can influence the production and sale of gold, which may adversely affect the performance of the Fund.

Risk of Investing in Precious Metals. Prices of precious metals and of precious metal-related financial instruments historically have been very volatile. The high volatility of precious metal prices may adversely affect the prices of financial instruments that derive their value from the price of underlying precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals.

Risk of Swap Agreements. A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. The Fund is required by financial regulators to post initial margin in connection with trading over-the-counter swaps. These requirements may raise the costs for the Fund’s investment in swaps.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to the investor protections of the 1940 Act. Changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in the Prospectus and the Statement of Additional Information (“SAI”), and could adversely affect the Fund.

Tax Risk. The Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these

investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a regulated investment company (“RIC”) for U.S. federal income tax purposes. Based on final regulations issued by the U.S. Internal Revenue Service (“IRS”) on which taxpayers may rely for taxable years beginning after September 28, 2016, the Fund expects its income with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues new regulations or other guidance, or Congress enacts legislation, limiting the circumstances in which the Fund’s income with respect to the Subsidiary will be considered “qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

Prior to March 1, 2021, the Fund did not seek to track the investment results of an index. The performance information below prior to March 1, 2021 is based on the performance of the Fund when BFA used an investment strategy substantially similar to the methodology of the Underlying Index. The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and the Underlying Index. Fund returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

iSHARES® COMMODITY CURVE CARRY STRATEGY ETF

Ticker: CCRVStock Exchange: NYSE Arca

Investment Objective

The iShares Commodity Curve Carry Strategy ETF (the “Fund”) seeks to track the investment results of an index composed of commodities with the top ten highest ranking roll yields, on a total return basis, selected from a broad commodity universe.

Fees and Expenses

The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through March 1, 2026. The contractual waiver may be terminated prior to March 1, 2026 only upon written agreement of the Trust and BFA.

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

Principal Investment Strategies

The Fund seeks to track the investment results of the ICE BofA Commodity Enhanced Carry Total Return Index (the “Underlying Index”), which measures the performance of the 10 commodity futures contracts representing the underlying commodities with the largest global production value, where more weight in the Underlying Index is given to those contracts having the highest degree of backwardation or lowest degree of contango (i.e., those with the highest “positive carry,” as explained below) among a universe of 22 futures contracts on physical agricultural, energy, precious metals, and industrial metals commodities listed on U.S. and non-U.S. futures exchanges, as determined by ICE Data Services, LLC (“IDI” or the “Index Provider”). The Underlying Index is rebalanced on a monthly basis and could contain more than 10 contracts during the rebalancing period.

The Fund, through its Subsidiary (as defined below), invests in financial instruments that provide exposure to commodities, and not in the physical commodities themselves. The Fund seeks to achieve its investment objective primarily by investing in total return swaps on the Underlying Index. The Fund reserves the right to invest in a broad range of financial instruments and expects to obtain a substantial amount of its exposure to the investment results of the Underlying Index by entering into total return swaps that provide returns similar to the commodity futures contracts included in the Underlying Index.

The Fund may invest in swaps on commodity futures contracts that are not included in the Underlying Index but that provide exposure to commodities from the same sectors as those found in the Underlying Index, as well as in futures, options and forwards that provide exposure to commodities from such sectors (collectively with total return swaps on the Underlying Index, the “Commodity Investments”). The Fund invests in Commodity Investments solely through its Subsidiary. Investing in Commodity Investments may have a leveraging effect on the Fund.

The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in Commodity Investments through a cash management strategy consisting primarily of investments in cash and cash equivalents, short-term government obligations, and short-term fixed-income securities (collectively, “Fixed-Income Investments”). The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s investments in derivatives on a day-to-day basis.

In order to maintain exposure to a futures contract on a particular commodity, an investor must sell the position in the expiring contract and buy a new position in a contract with a later delivery

month, which is referred to as “rolling.” If the price for the new futures contract is less than the price of the expiring contract, then the market for the commodity is said to be in “backwardation.” In these markets, investors experience positive roll returns, which is referred to as “positive carry.” The term “contango” is used to describe a market in which the price for a new futures contract is more than the price of the expiring contract. In these markets, investors experience negative roll returns, which is referred to as “negative carry.” The Underlying Index seeks to employ a positive carry strategy that emphasizes commodities and futures contract months with the greatest degree of backwardation and lowest degree of contango, resulting in net gains through positive roll returns.

The Fund is expected to establish new total return swap contracts on the Underlying Index on an ongoing basis and replace expiring contracts. Total return swaps subsequently acquired by the Fund may have terms that differ from the swaps the Fund previously held. The Fund generally expects to pay a fixed payment rate and swap-related fees to each counterparty and receive the total return of the Underlying Index, including, in the event of negative performance by the Underlying Index, a negative return (i.e., a payment from the Fund to the swap counterparty). As of October 31, 2024, the Underlying Index had 12 components.

The remainder of the Fund’s assets are invested directly by the Fund, primarily in Fixed-Income Investments, including repurchase agreements, money market instruments, U.S. government and agency securities, sovereign debt obligations on non-U.S. countries (excluding emerging market countries), commercial paper, non-convertible corporate debt securities, and obligations of U.S. and non-U.S. banks and similar institutions.

S-10

The Underlying Index is sponsored by the Index Provider, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Subsidiary) any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

Commodity-Linked Derivatives Risk. The commodities markets are volatile, and movements in the market price of one or more of the underlying commodities could cause the Fund to incur large losses. It is possible that the Fund could lose all or substantially all of its investment. Prices of commodity-linked investments have a historically low correlation with the returns of the stock and bond markets and are subject to change based on a variety of factors that may not be anticipated by the Fund’s adviser. The value of a commodity-linked derivative instrument (including swaps based on such instruments) typically is based upon the price movements of the underlying commodity or an economic variable linked to such price movements. The current market prices, or “spot prices,” and the price at a specified future date

implied by the value of certain commodity-linked derivatives (including swaps based on such instruments), or the “futures prices,” for commodities will vary depending upon expectations regarding market conditions. The value of commodity-linked investments tied to both spot and futures prices of commodities may fluctuate quickly and dramatically as a result of changes affecting a particular commodity and may not correlate to price movements in other asset classes, such as stocks, bonds and cash. Commodity-linked derivatives are subject to the risk that the counterparty to the transaction, the exchange or trading facility on which they trade or the applicable clearing house may default or otherwise fail to perform. The Fund’s use of commodity-linked derivatives may also have a leveraging effect on the Fund’s portfolio because of the leverage inherent in the use of derivatives. Leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have had. The Fund is required to post margin with respect to its holdings in derivatives. Each of these factors and events could have a significant negative impact on the Fund.

S-11

obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. The Fund is required by financial regulators to post initial margin in connection with trading over-the-counter swaps. These requirements may raise the costs for the Fund’s investment in swaps.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined below in Authorized Participant Concentration Risk), a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, or another fund may invest in the Fund and hold its investment for a specific period of time to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Cash Transactions Risk. The Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. As a result, the Fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

S-12

supply and demand for commodities, market events, war, regulatory developments, political instability, other catastrophic events, or other factors that the Fund cannot control could have an adverse impact on the Commodity Investments in which the Fund invests.

Counterparty Risk. Certain commodity-linked derivative instruments, uncleared swaps agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of a counterparty default, the Fund could experience lengthy delays in recovering some or all of its assets or obtain no recovery at all and, if the counterparty is subject to specified types of resolution proceedings, the Fund may be subject to stays that limit its ability to close out positions and limit risk. The Fund’s investments in the futures markets also introduce the risk that its futures commission merchant (“FCM”) could default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM’s obligation to return margin posted in connection with the Fund’s futures contracts.

Derivatives may create investment leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives are subject to the risk of mispricing or improper valuation, particularly if there is not a liquid secondary market for the instrument. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

Income Risk. The Fund’s income may decline when yields fall. This decline can occur because the Fund may subsequently invest in lower-yielding Fixed-Income Investments as Fixed-Income Investments in its portfolio mature, are near maturity or are called, or the Fund otherwise needs to purchase additional bonds.

S-13

the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties and thus may be more susceptible to the risks associated with these particular issuers or counterparties. As a result, the Fund's performance may depend to a greater extent on the performance of a small number of issuers or counterparties, which may lead to more volatility in the Fund’s NAV.

Risk of Investing in Agriculture and Livestock. Investments in the agricultural and livestock sectors may be volatile and change unpredictably as a result of many factors, such as legislative or regulatory developments relating to food safety, the imposition of tariffs or other trade restraints, and the supply and demand of each commodity. Increased competition and changes in consumer

tastes and spending can also influence the demand for agricultural and livestock products, affecting the price of such commodities and the performance of the Fund.

Risk of Investing in Industrial Metals. The industrial metals sector may be adversely affected by changes in international economic and political conditions, increased competition and changes in industrial and commercial demand for industrial metals. As a result, the price of industrial metals has been subject to substantial price fluctuations over short periods of time.

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if it does not meet certain requirements set by the listing exchange. Any resulting liquidation of the Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

S-14

with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues new regulations or other guidance, or Congress enacts legislation, limiting the circumstances in which the Fund’s income with respect to the Subsidiary will be considered “qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances.

certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® GSCI COMMODITY DYNAMIC ROLL STRATEGY ETF

Ticker: COMTStock Exchange: Nasdaq

Investment Objective

The iShares GSCI Commodity Dynamic Roll Strategy ETF (the “Fund”) seeks to track the investment results of an index composed of a broad range of commodity exposures with enhanced roll selection, on a total return basis.

Fees and Expenses

The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other registered investment companies advised by BFA, or its affiliates, through February 28, 2029. The contractual waiver may be terminated prior to February 28, 2029 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it, directly or through a subsidiary, buys and sells securities or other assets (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P GSCI Dynamic Roll (USD) Total Return Index (the “Underlying Index”), which measures the performance of futures contracts such as aluminum, Brent crude oil, cocoa, coffee, copper, corn, cotton, gas oil, feeder cattle, gold, heating oil, lean hogs, lead, live cattle, natural gas, nickel, silver, soybeans, sugar, unleaded gasoline, wheat, West Texas Intermediate crude oil and zinc. The Underlying Index is rebalanced on an annual basis.

The Fund, through its Subsidiary (as defined below), invests in financial instruments providing exposure to commodities and not in the physical commodities themselves. In seeking to achieve its investment objective, the Fund invests in a combination of exchange-traded commodity futures contracts, exchange-traded options on commodity-related futures contracts and exchange-cleared commodity-related swaps (together, “Commodity-Linked Investments”), thereby obtaining exposure to the commodities markets. Commodity-Linked Investments may also include exchange-cleared swaps on commodities and exchange-traded options on futures that provide exposure to the investment returns of the commodities markets. Investing in Commodity-Linked Investments may have a leveraging effect on the Fund.

The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in Commodity-Linked Investments through a cash management strategy consisting primarily of investments in short-term, investment-grade fixed-income securities that include U.S. government and agency securities, treasury inflation-protected securities, sovereign debt obligations of non-U.S. countries, and repurchase agreements, money market instruments and cash and other cash equivalents (collectively, “Fixed-Income Investments”). The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s Commodity-Linked Investments exposure on a day-to-day basis.

As of October 31, 2024, the Underlying Index had 24 components.

The Fund gains exposure to Commodity-Linked Investments by investing through a wholly owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and, unless otherwise noted in this Prospectus, is not subject to the investor protections of the 1940 Act. The Subsidiary invests solely in Commodity-Linked Investments and cash and cash equivalents.

In compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity-Linked Investments held in the Subsidiary are intended to provide the Fund with exposure to commodity markets within the limits of current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity-Linked Investments.

The remainder of the Fund’s assets are invested directly by the Fund, primarily in Fixed-Income Investments. The Fund or the Subsidiary may from time to time invest in other exchange-traded funds (“ETFs”), exchange-traded notes or commodity-linked notes.

The Underlying Index is sponsored by S&P Dow Jones Indices LLC (the “Index Provider”), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

S-19

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in (i) equity securities issued by commodity-related companies, derivatives with exposure to commodity-related companies or investments in securities and derivatives linked to the underlying price movement of commodities, including but not limited to commodity-linked derivatives such as commodity-linked notes, commodity futures, forward contracts and swaps and other similar derivative instruments and investment vehicles that invest in commodities, or commodity-linked derivatives, and (ii) the industry or group of industries that constitutes the energy sector. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Subsidiary) any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument typically is based upon the price movements of the underlying commodity or an economic variable linked to such price movements. The prices of commodity-linked investments may fluctuate quickly and dramatically as a result of changes affecting a particular commodity and may not correlate to price movements in other asset classes, such as stocks, bonds and cash. Commodity-linked derivatives are subject to the risk that the counterparty to the transaction, the exchange or trading facility on which they trade or the applicable clearing house may default or otherwise fail to perform. The Fund’s use of commodity-linked derivatives may also have a leveraging effect on the Fund’s portfolio because of the leverage inherent in the use of derivatives. Leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have had. The Fund is required to post margin with respect to its holdings in derivatives. Each of these factors and events could have a significant negative impact on the Fund.

contracts and other financial and economic factors; (v) a counterparty’s default in the performance of its obligations; (vi) the obligation to make daily cash payments to maintain the required margin for the futures contract; and (vi) the possibility that a failure to close a position may result in delivery of an illiquid commodity to the Fund.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in

S-20

comparison to financial markets generally, a particular financial market, another index, or other asset classes.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Commodity Risk. The Fund invests in instruments that are susceptible to fluctuations in certain commodity markets and to price changes due to trade relations, including the imposition of tariffs by the U.S. and other importing countries. Any negative changes in commodity markets that may be due to changes in supply and demand for commodities, market events, war, regulatory developments, political instability, other catastrophic events, or other factors that the Fund cannot control could have an adverse impact on Commodity-Linked Investments in which the Fund invests.

Counterparty Risk. Certain commodity-linked derivative instruments, uncleared swaps and other forms of financial instruments that involve counterparties subject the Fund to the

risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of a counterparty default, the Fund could experience lengthy delays in recovering some or all of its assets or obtain no recovery at all and, if the counterparty is subject to specified types of resolution proceedings, the Fund may be subject to stays that limit its ability to close out positions and limit risk. The Fund’s investments in the futures markets also introduce the risk that its futures commission merchant (“FCM”) could default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM’s obligation to return margin posted in connection with the Fund’s futures contracts.

S-21

not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

brokerage costs and/or have a material effect on the market price of Fund shares.

Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the Underlying Index and may hold securities or other assets not included in the Underlying Index, it is subject to the risk that the investment strategy of BFA and the Sub-Adviser may not produce the intended results. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.

S-22

controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Reliance on Trading Partners Risk. The Fund invests in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to North American Economic Risk.

for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. The Fund is required by financial regulators to post initial margin in connection with trading over-the-counter swaps. These requirements may raise the costs for the Fund’s investment in swaps.

Tax Risk. The Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a regulated investment company (“RIC”) for U.S. federal income tax purposes. Based on final regulations issued by the U.S. Internal Revenue Service (“IRS”) on which taxpayers may rely for taxable years beginning after September 28, 2016, the Fund expects its income with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues new regulations or other guidance, or Congress enacts legislation, limiting the circumstances in which the Fund’s income with respect to the Subsidiary will be considered “qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances.

S-23

purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® TRANSITION-ENABLING METALS ETF

Ticker: TMETStock Exchange: Nasdaq

Investment Objective

The iShares Transition-Enabling Metals ETF (the “Fund”) seeks to track the investment results of an index that provides exposure to metals that are essential to a wide range of clean energy technologies supporting the transition to a low-carbon economy.

Fees and Expenses

The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

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

Principal Investment Strategies

The Fund seeks to track the investment results of the ICE Clean Energy Transition Metals Index (the “Underlying Index”), which measures the performance of a basket of exchange-traded metals futures contracts representing the underlying metals that are extensively used in a wide range of clean energy technologies, as determined by ICE Data Indices, LLC (“IDI” or the “Index Provider”). Examples of such clean energy technologies include solar panels, wind turbines, fuel cells, and electric vehicle batteries. The Index Provider’s Commodity Index Advisory Committee uses government, agency, and private company data and reports relating to the current and expected future usage of metals within the clean energy transition, as well as consideration of the availability of commodity futures, listing exchange and liquidity level, to determine eligibility. The eligible commodity futures are reviewed at least annually and currently include futures contracts for copper, aluminum, silver, nickel, zinc, platinum, and cobalt.

In seeking to achieve its investment objective, the Fund, through its Subsidiary (as defined below), invests in financial instruments that provide the same or similar exposure to commodities as the components of the Underlying Index, and not in the physical commodities themselves. For example, the Fund may invest in “similar” metals futures contracts to those in the Underlying Index where exposure to the same underlying metal is available on a similar contract trading on a different exchange. To obtain its exposure to the commodities markets, the Fund may invest in a combination of exchange-traded commodity futures contracts and exchange-traded options on commodity-related futures contracts (together, “Commodity- Linked Investments”). Investing in Commodity-Linked Investments may have a leveraging effect on the Fund.

The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in Commodity-Linked Investments through a cash management strategy consisting primarily of investments in cash and cash equivalents, short-term, investment-grade fixed-income securities that include U.S. government and agency securities, Treasury Inflation-Protected Securities, sovereign debt obligations of non-U.S. countries, repurchase agreements and money market instruments (collectively, “Fixed-Income Investments”). The Fund uses Fixed-Income Investments as investments and to provide liquidity, serve as margin and/or collateralize the Subsidiary’s Commodity-Linked Investments exposure on a day-to-day basis.

The Underlying Index is rebalanced on a quarterly basis, at the same time as any rolling of futures contracts. The rebalancing weight for each contract is determined based on liquidity and production, with each of these factors contributing 50%.

The Index Provider calculates a contract’s liquidity by (i) aggregating the product of its daily settlement prices and volumes for the 12-month period ending two months prior to the roll period (“the Measurement Period”), and (ii) dividing the amount from (i) by the sum of the same calculation for all contracts held in the Underlying Index.

The production weight is based on each commodity's Global Production Value ("GPV"), which is intended to measure the relative importance in the global economy of each contract in the Underlying Index. A commodity's GPV is calculated by multiplying the commodity's global production quantity (based on the latest year in which all the contract production numbers are available) by the number of units in which those quantities are quoted, and then multiplying that figure by the Average Reference Price ("ARP") of the applicable contract over the Measurement Period. The ARP is the average of the official settlement or similar prices posted by the relevant exchange or its clearing house for a contract on each trading day during the Measurement Period. In addition, the ARP is taken from the same contracts used for the calculation of the liquidity weight (i.e., the contracts in clause (i) above).

Contract weights are subject to a minimum weight of 0.50% of the Underlying Index and a maximum weight of the lesser of (a) 30% of the Underlying Index or (b) 10 times the contract’s liquidity weight. Any excess weight from the implementation of these constraints is redistributed among the remaining contracts on a pro rata basis.

As of October 31, 2024, the Underlying Index had 7 components.

The Fund gains exposure to Commodity-Linked Investments by investing through a wholly owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and, unless otherwise noted in this Prospectus, is not subject to the investor protections of the 1940 Act. The Subsidiary will invest solely in Commodity-Linked Investments and cash and cash equivalents.

In compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity-Linked Investments held in the Subsidiary are intended to provide the Fund with exposure to commodity markets within the limits of current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity-Linked Investments.

The remainder of the Fund’s assets will be invested directly by the Fund, primarily in Fixed-Income Investments. The Fund may from time to time invest in other exchange-traded funds (“ETFs”), exchange-traded notes, swaps or commodity-linked notes.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the

S-28

risks of active management, such as poor selection of securities and/or other instruments. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

Because the Fund uses a strategy of investing in the same or similar metals futures contracts as the Underlying Index, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the components of its underlying index in approximately the same proportions as in the underlying index.

The Fund will invest at least 80% of its assets, plus the amounts of any borrowings for investment purposes, in the same or similar metals futures contracts as the Underlying Index. Cash and cash equivalent investments associated with a futures contract will be treated as part of that position for purposes of calculating the percentage of investments included in the same or similar metals futures contracts as the Underlying Index.

The Underlying Index is sponsored by IDI, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Index Funds

A share of a Fund represents an ownership interest in an underlying portfolio of securities and other instruments (as applicable) that is intended to track the Fund’s Underlying Index. An index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while each Fund is an actual investment portfolio. The performance of a Fund and that of its Underlying Index may vary for a number of reasons, including transaction costs, asset or currency valuations, corporate actions, timing variances and differences between the composition of a Fund’s portfolio and that of the Underlying Index resulting from the Fund’s use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to its Underlying Index.

From time to time, the provider of the Underlying Index (“Index Provider”) may make changes to the index methodology or other adjustments to a Fund’s Underlying Index. Unless otherwise determined by BFA, any such change will be reflected in the calculation of the Underlying Index’s performance on a going-forward basis after the effective date of such change. Therefore, the performance of the Underlying Index that is shown for periods prior to the effective date of any such change generally will not be recalculated or restated to reflect the change.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of the applicable underlying index. Because the Funds use representative sampling, they can be expected to have a larger tracking error than if they used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

Additional Information About the Funds' Risks

Each Fund is subject to various risks, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund discloses its portfolio holdings daily at www.iShares.com. You could lose all or part of your investment in a Fund, which could underperform other investments. The table below identifies the principal and other (non-principal) risks that apply to each Fund. A Fund that invests in an underlying fund (“Underlying Fund”) or a Subsidiary also may be indirectly exposed to these risks through such investment. A description of each risk is provided after the table.

Asset Class Risk. The securities and other assets in a Fund’s portfolio or, if applicable, its Underlying Index may underperform in comparison to indexes that track, or assets that represent, other countries or geographic units, industries, markets, market segments, or asset classes. Various types of securities, other assets and indexes may experience cycles of outperformance and underperformance in comparison to financial markets generally. This divergence may be due to a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause a Fund to underperform other investment vehicles that invest in different asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant, a third-party investor, a Fund’s adviser, an affiliate of a Fund’s adviser, or another fund may invest in a Fund and hold its investment for a specific period of time to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

guaranteed by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than U.S. government money market funds and retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

Cash Transactions Risk. Unlike most other ETFs, the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV.

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument (including swaps based on such instruments) typically is based upon the price movements of the underlying commodity or an economic variable linked to such price movements. Therefore, the value of commodity-linked derivative instruments may be affected by changes in overall economic conditions, interest rates, or factors affecting a particular commodity or industry, such as production, disease, climate conditions, supply or demand, politics, geopolitics, changes in international balance of payments and trade, currency devaluations and revaluations, market liquidity, and economic, political and regulatory developments. The current market prices, or “spot prices,” and the price at a specified future date implied by the value of certain commodity-linked derivatives (including swaps based on such instruments), or the “futures prices,” for commodities will vary depending upon expectations regarding market conditions. The value of commodity-linked investments tied to both spot and futures prices of commodities may fluctuate quickly and dramatically as a result of changes affecting a particular commodity and may or may not correlate to price movements in other asset classes, such as stocks, bonds and cash. Investments in commodity-linked derivatives may be subject to greater volatility than non-derivative based investments because of the leverage inherent in the use of derivatives. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop. Commodity-linked derivatives also may be subject to credit and interest rate risks that in general affect the values of fixed-income securities. Therefore, at maturity, the Fund may receive more or less principal than it originally invested. The Fund might receive interest payments that are more or less than the stated coupon interest payments. Commodity derivatives are subject to the risk that the counterparty to the transaction, the exchange or trading facility on which they trade or the applicable clearing house may default or otherwise fail to perform. In addition, each exchange or trading facility on which derivatives are traded has the right to suspend or limit trading in all futures or other instruments that it lists. The Fund’s use of commodity-linked derivatives can result in large amounts of financial leverage. Although the Fund will not borrow money in order to increase the amount of its trading, the low margin deposits normally required in futures trading permit a high degree of leverage on the investment itself. Accordingly, a relatively small price movement in a futures contract may result in immediate and substantial losses to the Fund. Like other leveraged investments, any trade may result in losses in excess of the amount invested. Each of these factors and events could have a significant negative impact on the Fund.

The constituents of the Underlying Index may experience such disruptions in trading. The Fund may be negatively impacted by the cessation of trading in futures contracts included in the Fund’s Underlying Index or by a futures exchange imposing a limit price. If there is a market disruption event on a day when the Fund enters into or terminates a swap transaction tied to the Underlying Index, there could be an adverse impact on the Fund’s portfolio and the performance of the Fund. Market disruption events may delay payments on swaps tied to the futures market. In order to meet redemption requests, the Fund may be forced to terminate swaps tied to the futures market at disadvantageous times or prices if a market disruption event persists beyond two consecutive business days.

In the event of a market disruption event, the execution price the Fund will pay or receive upon the settlement of a swap transaction tied to the Underlying Index may differ from the Fund’s initial valuation of the swap, which is based on the official closing price of the Underlying Index, which uses the limit price of the affected contract. Authorized Participants who purchase or redeem shares on a day when one or more constituents of the Underlying Index is experiencing a market disruption event could bear additional costs associated with increased market

risk because the execution price of the swap may differ from the value assigned to the swap on the day the Authorized Participant submits their creation or redemption order. Such market disruption events may have an adverse effect on the value of the Fund shares.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

The CFTC and the U.S. commodities exchanges impose limits referred to as “speculative position limits” on the maximum net long or net short speculative positions that any person may hold or control in any particular futures contracts (or options thereon) traded on U.S. commodities exchanges. CFTC rules impose position limits on certain futures contracts (and options thereon) and physical commodity swaps that are “economically equivalent” to such contracts. As a result of these position limits, the size or duration of positions available to the Fund may be severely limited.

Commodity Risk. Companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, war, catastrophic events, changes in interest rates and monetary and other governmental policies, action and inaction, including price changes due to trade relations. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Counterparty Risk. Certain commodity-linked derivative instruments, uncleared swaps and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of a counterparty default, the Fund could experience lengthy delays in recovering some or all of its assets or obtain no recovery at all and, if the counterparty is subject to specified types of resolution proceedings, the Fund may be subject to stays that limit its ability to close out positions and limit risk. The Fund may deposit funds required to margin open positions in the derivative instruments subject to the CEA with a clearing broker registered as an FCM, which is an entity that solicits or accepts orders to buy or sell commodity futures, options, swaps or forward contracts and accepts money or other assets from customers to support such orders. The FCM could default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM’s obligation to return margin posted in connection with the Fund’s futures contracts. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund shares may decrease. In addition, the Fund may engage in such investment transactions with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk.

Energy Sector Risk. The performance of energy-related commodities is generally cyclical and highly dependent on energy prices. Energy prices may fluctuate significantly due to, among other things, national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) and non-OPEC energy exporters, such as the Russian Federation, policies and relationships, and the economies of key energy-consuming countries. The market value of energy-related commodities may decline for many reasons, including, among other things: changes in the levels and volatility of global energy prices, energy supply and demand, and capital expenditures on exploration and production of energy sources; exchange rates, interest rates, economic conditions, and tax treatment; terrorism, natural disasters and other catastrophes; and energy conservation efforts, increased competition and technological advances. The energy sector may also be subject to substantial government regulation and contractual fixed pricing. In 2020, in the context of the COVID-19 outbreak and disputes among oil-producing countries regarding potential limits on the production of crude oil, the energy sector has experienced increased volatility. In particular, significant market volatility occurred in the crude oil markets as well as the oil futures markets, which resulted in the market price of the front month WTI crude oil futures contract falling below zero for a period of time.

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

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

Futures Commission Merchant Risk. The CEA requires an FCM to segregate funds deposited in a customer's commodity futures account. If the FCM fails to properly segregate customer funds, the Fund may be subject to a risk of loss of its funds on deposit in the event of the FCM's bankruptcy or insolvency. In addition, under certain circumstances, such as the inability of another customer of the FCM or its own inability to satisfy substantial deficiencies in such other customer's account, the Fund may be subject to a risk of loss of its funds on deposit even if such funds are properly segregated. In the case of any such bankruptcy or customer loss, the Fund might recover only a pro rata share of all property available for distribution to all of the FCM's customers. If no property is available for distribution to the FCM's customers, the Fund would not recover any of its assets on deposit with the FCM.

Income Risk. The Fund’s income may decline when yields fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable interest rates. The Fund’s income may decline because the Fund invests in lower yielding Fixed-Income Investments, as Fixed-Income Investments in its portfolio mature, are near maturity or are called, or when the Fund needs to purchase additional bonds.

Index-Related Risk. A Fund that tracks an Underlying Index seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of its Underlying Index as published by the Index Provider. There is no assurance that the Index Provider or its agents will construct or calculate the Underlying Index accurately. While the Index Provider describes what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability regarding the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA also does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors.

The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither a Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of an Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, particularly for indexes that are less commonly used as benchmarks. In addition, there may be heightened risks associated with the adequacy and reliability of information about emerging markets constituents, as such markets may have less information available or less regulatory oversight. Errors related to an Underlying Index may negatively or positively impact a Fund and its shareholders. For example, if the Underlying Index contains incorrect constituents, the Fund will have exposure to such constituents and will be underexposed to the Underlying Index’s other constituents. Shareholders should understand that any gains from an Index Provider’s errors will be kept by the Fund and its shareholders and any losses or costs from such errors will be borne by the Fund and its shareholders.

Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact an Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance to an Underlying Index. This could cause the Underlying Index to vary from its normal or expected composition. If a scheduled rebalance is postponed, index constituents that would otherwise be removed at the rebalance (due to, for example, changes in market capitalization or issuer credit ratings) may remain, causing the performance and constituents of the Underlying Index to vary from those expected under normal conditions. In addition, to the extent circumstances evolve between periodic index reviews and reconstitutions, an Underlying Index may include constituents that do not align with its objective or selection criteria, and the Fund tracking the Underlying Index may be similarly affected.

In addition to scheduled rebalances, an Index Provider or its agents may carry out ad hoc index rebalances due to reaching certain weighting constraints, unusual market conditions, corporate events, or corrections of errors. The relevant Fund will in turn rebalance its portfolio to attempt to increase the correlation between the portfolio and the Underlying Index. The Fund and its shareholders will directly bear any transaction costs and market exposure from such portfolio rebalancing. Therefore, index-related errors and ad hoc rebalances may increase a Fund’s costs and tracking error.

Interest Rate Risk. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. Changes in interest rates may have unpredictable effects on fixed-income markets and may result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. When interest rates rise, the value of fixed-income securities or other instruments sensitive to interest rates typically decreases. Duration is a measure of how sensitive a bond is to interest rate changes. Fixed-income securities with longer durations tend to be more sensitive to interest rate changes, and their prices usually are more volatile than those of shorter-duration securities. For example, if a bond has a duration of five years and interest rates rise, the price of the bond will likely decline by a greater percentage than for a bond with a one-year duration. To the extent a Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Fund’s investments to decline significantly, which would adversely affect the Fund’s performance.

when interest rates are set at low levels and the market prices of portfolio securities have increased, a Fund may have a very low or even negative yield, which would cause the Fund to lose money under certain conditions.

Management Risk. An index Fund invests in securities or other assets included in, or representative of, its Underlying Index, regardless of their investment merits. Such a Fund may be affected by a general decline in market segments related to its Underlying Index, and BFA generally does not attempt to invest the Fund’s assets in defensive positions under any market conditions, including declining markets. Market disruptions and regulatory restrictions could have an adverse effect on a Fund’s ability to adjust its exposure to the required levels in order to track its Underlying Index. Because BFA uses a representative sampling indexing strategy, a Fund will not fully replicate its Underlying Index and may hold securities or other assets not included in the Underlying Index. As a result, a Fund is subject to the risk that BFA’s investment strategy, whose implementation is subject to a number of constraints, may not produce the intended results. There is no guarantee that a Fund’s investment results will have a high degree of correlation to those of its Underlying Index or that a Fund will achieve its investment objective.

Non-Diversification Risk. A Fund that is classified as “non-diversified” may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties, compared with funds that are classified as “diversified.” A non-diversified Fund thus may be more susceptible to the risks associated with these particular issuers or counterparties. The gains and losses on such holdings may have a greater impact on a non-diversified Fund’s performance than they would on the performance of a diversified Fund, and a non-diversified Fund’s NAV may be more volatile.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. To the extent that a Fund makes investments in a limited number of countries, events in those countries will have a more significant impact on the Fund. The risks of investing in non-U.S. securities include the following, any of which may have an adverse impact on a Fund:

■

Less liquid markets, which may make valuing securities more difficult;

■

Greater market volatility;

■

Government intervention in issuers' operations or structure;

■

Government expropriation or nationalization of assets;

■

Exchange rate fluctuations and exchange controls;

■

Limitations on foreign ownership of securities;

■

Imposition of withholding or other taxes;

■

Restrictions on the repatriation of capital;

■

Higher transaction and custody costs;

■

Foreign market trading hours, different clearing and settlement procedures, and holiday schedules, which may limit a Fund's ability to

engage in portfolio transactions;

■

Less regulation of the securities and other financial markets;

■

Less availability of public information about issuers;

■

Weaker accounting, audit, disclosure and financial reporting requirements and the risk of being delisted from U.S. exchanges;

■

Difficulties in enforcing contractual obligations; and

■

Legal principals relating to corporate governance, directors’ fiduciary duties and liabilities, and shareholder rights that are less robust

than those that apply in the U.S.

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

Reliance on Trading Partners Risk. The economies of some countries or regions depend on trading with certain key trading partners. A reduction in spending on the products and services of these countries or regions, the institution of tariffs or other trade barriers by a key trading partner or a slowdown in the economy of a key trading partner may cause an adverse impact on the economies of such countries or regions and may negatively impact the performance of a Fund with exposure to those countries or regions.

Risk of Investing in Agriculture and Livestock. The agricultural and livestock sectors are subject to government subsidy policies and environmental, health and safety laws and regulations. Specific governmental policies, such as taxes, tariffs, duties, subsidies and import and export restrictions on agricultural commodities, commodity products and livestock, can influence the profitability of investing in agriculture and livestock. Import restrictions and tariffs that have recently been imposed by foreign countries on U.S. agricultural and livestock products are expected to negatively impact the profitability of investing in these products. These industries may also be adversely affected by changes in commercial and consumer demand for their products. A growing competitive landscape and increased availability of such commodities can influence: (i) the planting and raising of certain crops/livestock versus other uses of resources; (ii) the location and size of crop and livestock production; (iii) whether unprocessed or processed commodity products are traded; and (iv) the volume and types of imports and exports. Economic recession or labor difficulties may also lead to a decrease in demand for the products and services involved in agriculture. As a result, the price of agricultural or livestock commodities could decline, which would affect the performance of the Fund.

The agricultural and livestock sectors also are particularly sensitive to changing weather conditions, such as floods or droughts, natural disasters and other factors, such as disease outbreaks and pollution.

Risk of Investing in Developed Countries. Investment in developed country issuers will subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in Gold. The Fund has exposure to gold through its investments in total return swaps on the Underlying Index. Thus, the Fund’s portfolio may be adversely affected by changes or trends in the price of gold. The price of gold and of gold-related instruments historically has been volatile. Governments, central banks, or other large holders can influence the production and sale of gold, which may adversely affect the supply and price of gold, and thus, the performance of the Fund. Unpredictable economic, financial, social, and political factors may also affect the price of gold.

Investments related to gold are considered to be speculative. The price of gold may fluctuate sharply over short periods of time due to, among other things: (i) changes in inflation or expectations regarding inflation in various countries; (ii) the availability of supply; (iii) changes in demand; (iv) investment speculation and political uncertainty; and (v) monetary and other economic policies of various governments.

Risk of Investing in Industrial Metals. The price of industrial metals may be adversely affected by unpredictable international economic and political policies, such as currency devaluations or revaluations, economic and social conditions within an individual country, trade imbalances, or trade or currency restrictions between countries. As a result, the price of industrial metals historically has been subject to substantial price fluctuations over short periods of time.

This sector also could be adversely affected by changes in exchange rates and inflation, imposition of import controls, increased competition, and changes in industrial and commercial demand for industrial metals as the principal supplies of metal industries may be concentrated in a small number of countries and regions.

Risk of Investing in Precious Metals. Prices of precious metals and of precious metal-related financial instruments historically have been very volatile. The high volatility of precious metal prices may adversely affect the prices of financial instruments that derive their value from the price of underlying precious metals. The production and sale of precious metals by governments, central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metal-related financial instruments include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.

Some precious metals mining operation companies may hedge, to varying degrees, their exposure to declines in precious metals prices by selling forward future production. This may affect prices of precious metals-related financial instruments, which in turn may limit the Fund’s ability to benefit from future increases in the price of precious metals, thereby lowering returns to the Fund.

Additionally, increased environmental or labor costs may depress the value of mining and metal investments.

Risk of Swap Agreements.Swaps can involve greater risks than direct investment in securities or physical commodities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into on a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. The Fund is required by financial regulators to post initial margin in connection with trading over-the-counter swaps. These requirements may raise the costs for the Fund’s investment in swaps. Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. Swaps entered into by the Fund through its Subsidiary are not expected to be centrally cleared and thus will expose the Fund to counter-party default risk and illiquidity risk, as liquidity depends on the willingness of counterparties to enter into, and the ability of counterparties to hedge the risks of, such contracts. All swaps require posting of collateral, which may restrict the ability of the Fund to invest the assets in different ways and which involve costs to the Fund. Swaps provide customized contractual terms, which may not, in all cases, provide the hedging or other intended benefits.

Small Fund Risk. When a Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, a Fund may face the risk of being delisted if it does not meet certain requirements set by the listing exchange. If a Fund were required to delist from the listing exchange, the Fund’s value may rapidly decline and its performance may be negatively impacted. Any resulting liquidation of the Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Subsidiary Risk. In compliance with Subchapter M of the Internal Revenue Code, a Fund may invest up to 25% of its total assets, as determined at the end of the Fund's fiscal quarters, in a Subsidiary. By investing in a Subsidiary, a Fund is indirectly exposed to the risks associated with the Subsidiary's investments. For each Fund, the Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in the Prospectus, is not subject to the investor protections of the 1940 Act. The Trust's Board of Trustees has oversight responsibility for the investment activities of each Fund, including its investment in a Subsidiary, and the Fund's role as sole shareholder of the Subsidiary. Each Subsidiary follows the same compliance policies and procedures as the Funds. Each Subsidiary's financial statements are consolidated with the applicable Fund's financial statements.

Tax Risk. Each Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a RIC for U.S. federal income tax purposes. Based on final regulations issued by the IRS on which taxpayers may rely for taxable years beginning after September 28, 2016, each Fund expects its income with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues new regulations or other guidance, or Congress enacts legislation, limiting the circumstances in which each Fund’s income with respect to the Subsidiary will be considered

“qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances. Moreover, changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of each Fund and/or Subsidiary to operate as described in the Prospectus and in the SAI, and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

Tracking Error Risk. A Fund that tracks an index is subject to the risk of “tracking error,” which is the divergence of a Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in a Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by a Fund that the Underlying Index does not incur; a Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for a Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index, such as during a rebalancing or reconstitution; and impacts to a Fund of complying with certain regulatory requirements or limits. A Fund that tracks an index composed of a large number of securities or other assets may experience greater tracking error than a Fund that tracks a more narrow index. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions.

Transition-Enabling Metals Risk. The performance of transition-enabling metals (i.e., metals used to facilitate the energy transition from fossil fuels to environmentally cleaner energy sources and technologies) is highly dependent on energy prices and renewable and alternative energy companies. Transition-enabling metals may themselves not be considered environmentally “clean” by other investors, investment advisers or index providers. Investments in transition-enabling metals may be speculative and subject to greater price volatility than investments in other types of assets. The prices of transition-enabling metals may fluctuate significantly due to, among other things, national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) and non-OPEC energy exporters, such as the Russian Federation, policies and relationships, and the economies of key energy-consuming countries. The market value of transition-enabling metals may be significantly affected for many reasons, including, among other things: obsolescence of existing technology; trade treaties; the success of exploration projects; changes in the levels and volatility of global energy prices, supply and demand of alternative energy fuels, and capital expenditures on exploration and production of energy sources; worldwide metal prices and extraction and production costs; exchange rates, interest rates, economic conditions, government regulations and subsidies, supply chains and tax treatment; events in the regions which the Fund has exposure (e.g., expropriation, nationalization, confiscation of assets and property of mining companies, the imposition of restrictions on foreign investments or repatriation of capital, military coups, social or political unrest, terrorism, war, natural disasters and other catastrophes); and energy conservation efforts, increased competition and technological advances. Such risks may be heightened to the extent the Fund’s Commodity-Linked Investments provide exposure to emerging markets. Renewable and alternative energy companies have recently benefited from government policies such as the “Clean Vehicle Credit” under the Inflation Reduction Act, but there is no assurance that such policies will continue, which could have a negative impact on the Fund’s investments. In addition, the industry is relatively nascent and under-researched in comparison to more established and mature sectors, and should therefore be regarded as having greater investment risk.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances (e.g., reaching the legislative “debt ceiling”) could arise that could prevent the timely payment of interest or principal. An actual or threatened failure of the U.S. government to pay its obligations would result in losses to a Fund holding such securities as well as substantial negative consequences for the U.S. economy and the global financial system.

Changes in the U.S. government’s financial condition or credit rating may cause the value of U.S. Treasury obligations to decline. Because U.S. government debt obligations are often used as a benchmark for other borrowing arrangements, a downgrade to the credit rating of the U.S. could result in higher interest rates for a range of borrowers, cause disruptions in the international bond markets and have a substantial adverse effect on the U.S. and global economies.

A high national debt level may increase market pressures to meet government funding needs, which may drive debt costs higher and lead the government to issue additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that the U.S. government will not be able to make principal or interest payments when they are due. If market participants determine that U.S. sovereign debt levels are unsustainable, the value of the U.S. dollar could decline, thus increasing inflationary pressures and constraining the U.S. government’s ability to implement effective countercyclical fiscal policy in economic downturns.

Dividends and Distributions

Taxes

Taxes on Fund Distributions

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

and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. However, for tax years beginning after December 31, 2017 and before January 1, 2026, a Fund may report dividends eligible for a 20% “qualified business income” deduction for non-corporate U.S. shareholders to the extent that the Fund’s income is derived from ordinary REIT dividends, reduced by allocable Fund expenses.

Substitute dividends received by a Fund with respect to dividends paid on securities lent out, if any, will not be qualified dividend income.

iSHARES® INFLATION HEDGED CORPORATE BOND ETF

Ticker: LQDIStock Exchange: Cboe BZX

Investment Objective

The iShares Inflation Hedged Corporate Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the inflation risk of a portfolio composed of U.S. dollar-denominated, investment grade corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD” or the “Underlying Fund”), after taking into account any fee waivers by LQD, plus 0.05% through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

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

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)1

0.20%	None	0.00%	0.13%	0.33%	(0.15)%	0.18%

S-1

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Inflation Hedged Corporate Bond Index (the “Underlying Index”), which is designed to minimize the inflation risk of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds, represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 inflation swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components, as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund invests in U.S. dollar-denominated, investment-grade corporate bonds primarily through its investment in the Underlying Fund. The Fund seeks to track the inflation hedging component of the Underlying Index primarily through the use of positions in inflation swaps (i.e., contracts in which the Fund makes fixed-rate payments based on a notional reference amount while receiving floating-rate payments on the same notional reference amount determined from an inflation index). The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s inflation exposure at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the inflation swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new inflation swap contracts to the Underlying Index and remove the previous month’s inflation swap contracts.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in component securities and instruments in the Fund’s Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

investments in inflation hedging instruments are not intended to mitigate credit risk or other factors influencing the price of investment-grade corporate bonds, which may have a greater impact than inflation rates. Moreover, to the extent that inflation exposure has been priced into the investment-grade corporate bonds owned by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject a registered investment company and its adviser to regulation by the CFTC if the registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if the registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of such instruments above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”). BFA is considered a commodity pool operator (“CPO”) with respect to the Fund and is subject to regulation by the CFTC and the National Futures Association (“NFA”).

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively have an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund or the Underlying Fund may or may not hold all of the securities and/or other instruments in the applicable Underlying Index.

The Fund may lend securities from its portfolio representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index is sponsored by the Index Provider, an affiliated person of the Fund and of BFA, the Fund’s investment adviser. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a

S-2

particular industry or group of industries to approximately the same extent that an underlying fund is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Inflation-Linked Instruments Risk. There can be no assurance that the Consumer Price Index (“CPI”), which typically is referenced by inflation swaps, or any other inflation index will accurately measure the rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. CPI swaps may cause the Fund’s NAV and returns to be more volatile and expose the Fund to counterparty risk. The Fund could lose money on both the inflation hedging instruments and the investment-grade corporate bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

Hedging Risk. The Fund’s use of inflation hedging instruments is intended solely to mitigate the impact of inflation on the performance of bonds in its portfolio. The hedging strategy is not intended to mitigate credit risk, interest rate risk, or other factors, which may have a greater impact than inflation on the bonds’ returns. There is no guarantee that hedging will completely eliminate the impact of inflation on the Fund’s bond portfolio. In addition, if interest rates exceed the inflation rate, the Fund’s investments will generally underperform a portfolio composed solely of the bonds. In certain low inflation environments, the hedging strategy could result in disproportionately larger losses in the hedging positions as compared to gains in the bond positions attributable to interest rate changes. The Fund seeks to hedge only the impact of inflation and, as a result, if floating interest rates exceed inflation-linked rates, the Fund will not be hedged. There is no guarantee that the Fund will have positive returns, even in times of sharply rising inflation, during which the Fund’s hedging might be expected to mitigate the effects of inflation. The Fund incurs expenses when entering into hedging positions. Moreover, to the extent that inflation risk has been priced into

bonds held by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Investment in Underlying Fund Risk. The Fund invests in the Underlying Fund, so the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other assets that the Fund holds. The shares of the Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in the Fund will indirectly bear the expenses charged by the Underlying Fund, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Fund.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-3

transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

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

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

liquid assets they must maintain and their size, among other things. Financial services companies also may be significantly affected by, among other things, interest rates, economic conditions, volatility in financial markets, credit rating downgrades, adverse public perception, exposure concentration and counterparty risk.

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

Inflation Risk. The Fund seeks to mitigate many of the adverse impacts of inflation on investment-grade corporate bonds held by the Fund or the Underlying Fund and their issuers primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

S-4

Interest Rate Swap Risk. Interest rate swaps are subject to risks applicable to swaps generally, including the risk that a counterparty fails to meet its obligations and the risk that the Fund is not able to liquidate such swap in a timely manner or at all, which could result in losses to the Fund. Because the Fund invests in swaps that are subject to central clearing, these swaps are subject to the risk that a central clearinghouse will go into bankruptcy or become non-operational, and sometimes involve increased transaction costs. Counterparties to OTC swaps are not subject to these risks. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund. Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation.

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy. The Underlying Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies, consistent with its objective to track the performance of the Underlying Index.

S-5

may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Fund does not select investments based on investor protection considerations.

Risk of Investing in the China Bond Market. The Fund invests directly in the domestic bond market in the People’s Republic of China (“China” or the “PRC”) (the “China Interbank Bond Market”) through the Bond Connect trading channel. All bonds traded through Bond Connect are registered in the name of the PRC’s Central Moneymarkets Unit (“CMU”), which holds such bonds as a nominee owner. The precise nature and rights of the Fund as the beneficial owner of bonds traded in the China Interbank Bond Market through CMU as nominee are relatively new and untested areas of PRC law, and the exact nature of the Fund’s remedies and methods of enforcement of its rights and interests under PRC law are uncertain.

Market volatility and potential lack of liquidity due to low trading volume of certain bonds in the China Interbank Bond Market may result in the prices of certain bonds fluctuating significantly. Also, the systems used to trade through Bond Connect may not function as expected. Trading through Bond Connect is also subject to regulatory risks, including laws and regulations that are subject to change. There can be no assurance that Bond Connect or its features or systems will not be materially altered, suspended, discontinued or abolished. The Fund may be subject to additional taxation if certain tax exemptions under PRC tax regulations are withdrawn or amended. Any taxes arising from or to the Fund may be directly borne by, or indirectly passed on to, the Fund, which may substantially impact its NAV. Investing through Bond Connect subjects the Fund to currency risk, to the extent that currency rates used for Bond Connect are different than the rates used in the China Interbank Bond Market.

investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”). Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes.

S-6

methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-

valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

Prior to December 1, 2021, the Fund did not seek to track the investment results of an index. The performance information below prior to December 1, 2021 is based on the performance of the Fund when BFA used an investment strategy substantially similar to the methodology of the Underlying Index. The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and the Underlying Index. Fund returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information, including the Fund’s current NAV, may be obtained by visiting www.iShares.com or by calling 1-800-iShares (1-800-474-2737) (toll free).

iSHARES® INFLATION HEDGED HIGH YIELD BOND ETF

Ticker: HYGIStock Exchange: NYSE Arca

Investment Objective

The iShares Inflation Hedged High Yield Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the inflation risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG” or the “Underlying Fund”), after taking into account any fee waivers by HYG, plus 0.05% through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Inflation Hedged High Yield Bond Index (the “Underlying Index”). The Underlying Index is designed to minimize the inflation risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds, which is represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 inflation swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components (including shares of the Underlying Fund), as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund uses its investment in the Underlying Fund primarily to gain exposure to U.S. dollar-denominated, high yield corporate bonds (commonly referred to as “junk bonds”). The Fund seeks to track the inflation hedging component of the Underlying Index primarily through the use of positions in inflation swaps (i.e., derivative contracts used to transfer inflation exposure by exchanging a fixed cash flow for a floating cash flow). The Fund makes fixed-rate payments based on a notional reference amount while receiving floating-rate payments on the same notional reference amount determined from an inflation index. The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s inflation exposure at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

The Fund may also invest in other instruments designed to transfer inflation exposure from one party to another, including

but not limited to U.S. Treasury Inflation Protected Securities (“TIPS”), total return swaps, futures and options (collectively with inflation swaps, “inflation hedging instruments”). The Fund’s investments in inflation hedging instruments are not intended to mitigate credit risk or other factors influencing the price of U.S. dollar-denominated, high yield corporate bonds, which may have a greater impact than inflation rates. Moreover, to the extent that inflation exposure has been priced into the U.S. dollar-denominated, high yield corporate bonds owned by the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

The Fund may lend securities from its portfolio representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

Summary of Principal Risks

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

Inflation-Linked Instruments Risk. There can be no assurance that the Consumer Price Index (“CPI”), which typically is referenced by inflation swaps, or any other inflation index will accurately measure the rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. CPI swaps may cause the Fund’s NAV and returns to be more volatile and expose the Fund to counterparty risk. The Fund could lose money on both the inflation hedging instruments and the high yield corporate bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

hedging might be expected to mitigate the effects of inflation. The Fund incurs expenses when entering into hedging positions. Moreover, to the extent that inflation risk has been priced into bonds held by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-11

of the Fund would be maintained at such levels, which could negatively impact the Fund.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Industrial Companies Risk. Industrial companies face a number of risks, including supply chain and distribution disruptions, business interruptions, product obsolescence, third-party vendor risks, cyber attacks, trade disputes, product recalls, liability claims, scarcity of materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and currencies. The performance of such companies may also be affected by technological developments, labor relations, legislative and regulatory changes, government spending policies, and changes in domestic and international economies.

Inflation Risk. The Fund seeks to mitigate many of the adverse impacts of inflation primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the

S-12

Underlying Index and may hold securities or other assets not included in the Underlying Index, it is subject to the risk that the investment strategy of BFA may not produce the intended results. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Risk of Investing in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and

economic risks that are specific to the U.S. Certain changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may have an adverse effect on U.S. issuers.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of

the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking

error than ETFs that do not track such indexes. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® INFLATION HEDGED U.S. AGGREGATE BOND ETF

Ticker: AGIHStock Exchange: NYSE Arca

Investment Objective

The iShares Inflation Hedged U.S. Aggregate Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the inflation risk of a portfolio composed of U.S. dollar-denominated, investment-grade bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares Core U.S. Aggregate Bond ETF (“AGG” or the “Underlying Fund”), after taking into account any fee waivers by AGG, plus 0.10% through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

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

S-17

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 2% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Inflation Hedged U.S. Aggregate Bond Index (the “Underlying Index”). The Underlying Index is designed to minimize the inflation risk of a portfolio composed of U.S. dollar-denominated, investment-grade bonds, which is represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 inflation swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components (including shares of the Underlying Fund), as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund uses its investment in the Underlying Fund primarily to gain exposure to U.S. dollar-denominated, investment-grade bonds. To be included in the Underlying Fund, securities must have $300 million or more of outstanding face value and must have at least one year remaining to maturity, with the exception of amortizing securities such as mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”), which have lower thresholds as defined by the Underlying Fund's index provider. The Fund seeks to track the inflation hedging component of the Underlying Index primarily through the use of positions in inflation swaps (i.e., derivative contracts used to transfer inflation exposure by exchanging a fixed cash flow for a floating cash flow). The Fund makes fixed-rate payments based on a notional reference amount while receiving floating-rate payments on the same notional reference amount determined from an inflation index. The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s inflation exposure at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may also invest in other instruments designed to transfer inflation exposure from one party to another, including but not limited to U.S. Treasury Inflation Protected Securities (“TIPS”), total return swaps, futures and options (collectively with inflation swaps, “inflation hedging instruments”). The Fund’s investments in inflation hedging instruments are not intended to mitigate credit risk or other factors influencing the price of U.S. dollar-denominated, investment-grade bonds, which may have a greater impact than inflation rates. Moreover, to the extent that inflation exposure has been priced into the U.S. dollar-denominated, investment-grade bonds owned by the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

The Fund may lend securities from its portfolio representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

S-18

The Underlying Index is sponsored by the Index Provider, which is an affiliated person of the Fund and of BFA, the Fund’s investment adviser. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Inflation-Linked Instruments Risk. There can be no assurance that the Consumer Price Index (“CPI”), which typically is referenced by inflation swaps, or any other inflation index will accurately measure the rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. CPI swaps may cause the Fund’s NAV and returns to be more volatile and expose the Fund to counterparty risk. The Fund could lose money on both the inflation hedging instruments and the investment-grade bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

only the impact of inflation and, as a result, if floating interest rates exceed inflation-linked rates, the Fund will not be hedged. There is no guarantee that the Fund will have positive returns, even in times of sharply rising inflation, during which the Fund’s hedging might be expected to mitigate the effects of inflation. The Fund incurs expenses when entering into hedging positions. Moreover, to the extent that inflation risk has been priced into bonds held by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-19

Fund and hold its investment for a specific period of time to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

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

Inflation Risk. The Fund seeks to mitigate many of the adverse impacts of inflation on investment-grade bonds held by the Fund or the Underlying Fund and their issuers primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

S-20

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Fund does not select investments based on investor protection considerations.

S-21

subject to change. There can be no assurance that Bond Connect or its features or systems will not be materially altered, suspended, discontinued or abolished. The Fund may be subject to additional taxation if certain tax exemptions under PRC tax regulations are withdrawn or amended. Any taxes arising from or to the Fund may be directly borne by, or indirectly passed on to, the Fund, which may substantially impact its NAV. Investing through Bond Connect subjects the Fund to currency risk, to the extent that currency rates used for Bond Connect are different than the rates used in the China Interbank Bond Market.

Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs.

U.S. Agency Mortgage-Backed Securities Risk. The Underlying Fund invests in MBS issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, some of which may not be backed by the full faith and credit of the U.S. government. MBS represent interests in “pools” of mortgages and are subject to interest rate, prepayment, and extension risk. MBS react differently to changes in interest rates than other bonds, and the prices of MBS may reflect adverse economic and market conditions. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS. MBS are also subject to the risk of default on the underlying mortgage loans, particularly during periods of economic downturn. Default or bankruptcy of a counterparty to a to-be-announced (“TBA”) transaction would expose the Fund to possible losses.

S-22

of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal.

the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® INTEREST RATE HEDGED CORPORATE BOND ETF

Ticker: LQDHStock Exchange: NYSE Arca

Investment Objective

The iShares Interest Rate Hedged Corporate Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, investment grade corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD” or the “Underlying Fund”), after taking into account any fee waivers by LQD, plus 0.10% through February 28, 2027. The contractual waiver may be terminated prior to February 28, 2027 only upon written agreement of the Trust and BFA.

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 9% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Interest Rate Hedged Corporate Bond Index (the “Underlying Index”), which is designed to minimize the interest rate risk exposure of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds, represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 interest rate swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components (including the Underlying Fund), as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund invests in U.S. dollar-denominated, investment-grade bonds primarily through its investment in the Underlying Fund and/or through direct investment in bonds included in the underlying index of the Underlying Fund. To be included in the Underlying Fund, bonds must have: (i) at least three years to maturity; and (ii) at least three years and 6 months to maturity for new index insertions. The Fund seeks to track the interest rate hedging component of the Underlying Index primarily through the use of positions in interest rate swaps (i.e., contracts in which the Fund makes fixed-rate payments while receiving floating-rate payments based on a reference rate). The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s duration exposure (i.e., sensitivity to changes in interest rates) at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in component securities and instruments in the Fund’s Underlying Index and/or bonds included in the underlying index of the Underlying Fund. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may also invest in other interest rate futures contracts, including but not limited to, U.S. Treasuries, Eurodollar and Federal Funds futures. The Fund’s interest rate swap and futures positions are not intended to mitigate credit risk or other factors influencing the price of investment-grade corporate bonds, which may have a greater impact than interest rates.

The CFTC has adopted certain requirements that subject registered investment companies and their advisers to regulation by the CFTC if a registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if a registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s use or potential use of such instruments above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”). BFA is considered a commodity pool operator (“CPO”) with respect to the Fund and is subject to regulation by the CFTC and the National Futures Association (“NFA”).

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively have an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund and the Underlying Fund may or may not hold all of the securities and/or other instruments in the applicable Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

(including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Hedging Risk. The Fund’s use of interest rate hedging instruments is intended solely to mitigate the impact of interest rates on the performance of bonds in its portfolio. The hedging strategy is not intended to mitigate credit risk, inflation risk, or other factors, which may have a greater impact than interest rates on the bonds’ returns. There is no guarantee that hedging will completely eliminate the impact of interest rates on the Fund’s bond portfolio. In addition, if interest rates fall, long-only bond investments may perform better than the Fund’s investments. In certain falling interest rate environments, the hedging strategy could result in disproportionately larger losses in the hedging positions as compared to gains in the bond positions attributable to interest rate changes. There is no guarantee that the Fund will have positive returns, even in times of sharply rising interest rates, during which the Fund’s hedging might be expected to mitigate the effects of such rises. The Fund incurs expenses when entering into hedging positions.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-28

shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

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

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

conditions, volatility in financial markets, credit rating downgrades, adverse public perception, exposure concentration and counterparty risk.

S-29

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation.

may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”). Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® INTEREST RATE HEDGED HIGH YIELD BOND ETF

Ticker: HYGHStock Exchange: NYSE Arca

Investment Objective

The iShares Interest Rate Hedged High Yield Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG” or the “Underlying Fund”), after taking into account any fee waivers by HYG, plus 0.05% through February 28, 2027. The contractual waiver may be terminated prior to February 28, 2027 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 1% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Interest Rate Hedged High Yield Bond Index (the “Underlying Index”), which is designed to minimize the interest rate risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds (which are considered below investment-grade), represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 interest rate swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components, as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund invests in U.S. dollar-denominated, high yield corporate bonds primarily through its investment in the Underlying Fund. To be included in the Underlying Fund, bonds must have: (i) an original maturity date of less than 15 years; (ii) at least one year to maturity; and (iii) at least one year and 6 months to maturity for new index insertions. The Fund seeks to track the interest rate hedging component of the Underlying Index primarily through the use of positions in interest rate swaps (i.e., contracts in which the Fund makes fixed-rate payments while receiving floating-rate payments based on a reference rate). The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s duration exposure (i.e., sensitivity to changes in interest rates) at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

The Fund may also invest in other interest rate futures contracts, including but not limited to, U.S. Treasuries, Eurodollar and

Federal Funds futures. The Fund’s interest rate swap and futures positions are not intended to mitigate credit risk or other factors influencing the price of high yield corporate bonds, which may have a greater impact than interest rates.

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively have an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund and the Underlying Fund may or may not hold all of the securities and/or other instruments in the applicable Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that an underlying fund is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase

S-35

agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

Investment in Underlying Fund Risk. The Fund invests in the Underlying Fund, so the Fund’s investment performance and risks

are likely to be directly related to those of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other assets that the Fund holds. The shares of the Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in the Fund will indirectly bear the expenses charged by the Underlying Fund, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Fund.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-36

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

S-37

own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Privately Issued Securities Risk. Privately issued securities are securities that have not been registered under the Securities Act of 1933, as amended (the “1933 Act”). Such securities typically

are subject to legal restrictions on resale and generally are not traded in established public markets. As a result, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities, may be subject to wide fluctuations in value and may have higher transaction costs. There can be no assurance that a trading market will exist at any time for any particular privately issued security. Difficulty in selling such securities at a desirable time or price may result in a loss to the Fund.

S-38

Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking

error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® INTEREST RATE HEDGED LONG-TERM CORPORATE BOND ETF

Ticker: IGBHStock Exchange: NYSE Arca

Investment Objective

The iShares Interest Rate Hedged Long-Term Corporate Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated investment-grade corporate bonds with remaining maturities greater than ten years.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares 10+ Year Investment Grade Corporate Bond ETF (“IGLB” or the “Underlying Fund”), after taking into account any fee waivers by IGLB, plus 0.10% through February 28, 2027. The contractual waiver may be terminated prior to February 28, 2027 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 13% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Interest Rate Hedged Long-Term Corporate Bond Index (the “Underlying Index”), which is designed to minimize the interest rate exposure of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds with remaining maturities greater than ten years, represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 interest rate swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components (including the Underlying Fund), as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund invests in U.S. dollar-denominated, investment-grade corporate bonds primarily through its investment in the Underlying Fund and/or through direct investment in bonds included in the underlying index of the Underlying Fund. The bonds in which the Underlying Fund invests generally have at least ten years until maturity at the time of investment. Under normal circumstances, the Fund and the Underlying Fund seek to maintain a weighted average maturity that is greater than ten years. Weighted average maturity is a U.S. dollar-weighted average of the remaining term to maturity of the securities in the Underlying Fund’s portfolio.

The Fund seeks to track the interest rate hedging component of the Underlying Index primarily through the use of positions in interest rate swaps (i.e., contracts in which the Fund makes fixed-rate payments while receiving floating-rate payments based on a reference rate). The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s duration exposure (i.e., sensitivity to changes in interest rates) at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

Underlying Fund. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively have an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund and the Underlying Fund may or may not hold all of the securities and/or other instruments in the applicable Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

positions as compared to gains in the bond positions attributable to interest rate changes. There is no guarantee that the Fund will have positive returns, even in times of sharply rising interest rates, during which the Fund’s hedging might be expected to mitigate the effects of such rises. The Fund incurs expenses when entering into hedging positions.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Healthcare Companies Risk. The profitability of healthcare companies may be adversely affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, the protection and expiration of patents, limited product lines, supply chain issues, labor shortages and product liability claims, among other factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may

S-45

decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the

security’s maturity, which may cause the Fund or the Underlying Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.

meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Fund does not select investments based on investor protection considerations.

Risk of Investing in Saudi Arabia. Investing in Saudi Arabian issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to Saudi Arabia. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of the Fund’s investments. Such heightened risks may include, among others, the expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. Instability in the Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.

The ability of foreign investors to invest in the securities of Saudi Arabian companies could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership of such securities. There are a number of ways to conduct transactions in equity securities in the

Saudi Arabian market. The Fund generally expects to transact in a manner so that it is not limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund, which may have an adverse impact on the prices, quantity or timing of Fund transactions.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry

S-47

competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options,

futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes.

Utility Companies Risk. The utilities sector is generally subject to significant government regulation and oversight, including restrictions on rates as well as environmental and other regulations. Utility companies also may face risks related to, among other things, natural disasters, cyber or other attacks, capital project funding, energy price volatility and increased competition.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

iSHARES® INTEREST RATE HEDGED U.S. AGGREGATE BOND ETF

Ticker: AGRHStock Exchange: NYSE Arca

Investment Objective

The iShares Interest Rate Hedged U.S. Aggregate Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, investment-grade bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares Core U.S. Aggregate Bond ETF (“AGG” or the “Underlying Fund”), after taking into account any fee waivers by AGG, plus 0.10% through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

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

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 2% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Interest Rate Hedged U.S. Aggregate Bond Index (the “Underlying Index”), which is designed to minimize the interest rate risk exposure of a portfolio composed of U.S. dollar-denominated, investment-grade bonds, represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 interest rate swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components, as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund invests in U.S. dollar-denominated, investment-grade bonds primarily through its investment in the Underlying Fund. To be included in the Underlying Fund, securities must have $300 million or more of outstanding face value and must have at least one year remaining to maturity, with the exception of amortizing securities such as mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”), which have lower thresholds as defined by the Underlying Fund's index provider. The Fund seeks to track the interest rate hedging component of the Underlying Index primarily through the use of positions in interest rate swaps (i.e., contracts in which the Fund makes fixed-rate payments while receiving floating-rate payments based on a reference rate). The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s duration exposure (i.e., sensitivity to changes in interest rates) at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

The Fund may also invest in other interest rate futures contracts, including but not limited to, U.S. Treasuries, Eurodollar and Federal Funds futures. The Fund’s interest rate swap and futures positions are not intended to mitigate credit risk or other factors influencing the price of U.S. dollar-denominated, investment-grade bonds, which may have a greater impact than interest rates.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

Summary of Principal Risks

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Interest Rate Swap Risk. Interest rate swaps are subject to risks applicable to swaps generally, including the risk that a counterparty fails to meet its obligations and the risk that the Fund is not able to liquidate such swap in a timely manner or at all, which could result in losses to the Fund. Because the Fund invests in swaps that are subject to central clearing, these swaps are subject to the risk that a central clearinghouse will go into bankruptcy or become non-operational, and sometimes involve increased transaction costs. Counterparties to over-the-counter (“OTC”) swaps are not subject to these risks. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund. Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-53

creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

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

Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be

sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

S-54

or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy. The Underlying Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies, consistent with its objective to track the performance of the Underlying Index.

less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking error than ETFs that do not track such indexes. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Changes in the U.S. government’s financial condition or credit rating may cause the value of U.S. Treasury obligations to decline. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal.

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

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Consumer Goods and Services Companies Risk. Many consumer goods and services companies (“consumer companies”) rely heavily on disposable household income and consumer spending and may be impacted by social trends, marketing campaigns, demographic shifts and other factors affecting consumer preferences and demand. In addition, damage to a brand or a reputation crisis can have a substantial adverse impact on consumer companies.

Certain consumer companies, such as those providing discretionary goods or services, may depend more on business cycles, overall economic conditions and consumer confidence. Many consumer goods and services are subject to government regulation and the related compliance costs, and consumer companies also face the risk of product liability claims. Consumer companies also may be adversely affected by volatility in commodity prices, supply chain disruptions and labor shortages.

A Fund’s portfolio may include below investment-grade bonds, which generally are subject to greater levels of credit risk than higher rated securities. There is the chance that a Fund’s holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing the Fund’s income level and share price. Debt instruments are subject to varying degrees of credit risk, depending on the issuer’s or counterparty’s financial condition and on the terms of the obligation, which may be reflected in their credit ratings.

Custody Risk. Custody risk refers to the risks in the process of clearing and settling trades, as well as the holding of securities and other assets by local banks, agents and depositories. These risks are heightened in jurisdictions with less developed markets or less robust settlement and custody infrastructure and processes, and they may result in losses or delays in payments, delivery or recovery of money or other assets. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle. Governments or trade groups may compel local agents to hold securities and other assets in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities markets are, the higher the degree of custody risk.

ownership of Fund shares, and other data integral to a Fund’s functioning inaccessible, inaccurate or incomplete. A Fund may incur substantial costs in order to resolve or prevent cyber incidents.

Energy Companies Risk. The energy sector tends to be closely tied to the economic cycle and can be significantly affected by supply-demand dynamics and volatility in commodity prices. Energy companies also may be adversely affected by exchange rate fluctuations, war or other conflicts, sanctions, import/export controls, depletion of resources, technological advances and labor relations. This sector generally is subject to substantial government regulation, and companies may incur significant costs in complying with environmental and other laws. Policies that promote energy conservation, clean energy or the transition to low carbon alternatives also may affect the performance of energy companies.

Energy companies may depend on a relatively small number of customers, including governmental entities and utilities. The exploration and production of energy sources and the development of energy infrastructure often require significant capital expenditures, and companies may face high interest costs and difficulty in raising capital. Energy companies also may face challenges from operating in countries with a history of adverse policies or events, such as expropriation, confiscation of assets, corruption, political instability and social unrest. The operations of energy companies may be disrupted by events that target or damage energy infrastructure, including cyber or other attacks, accidents and natural disasters. Energy companies are at risk of liability for environmental harm and other types of damages.

The energy sector may experience significant market volatility. For example, Russia’s large-scale invasion of Ukraine in 2022 led to disruptions and increased volatility in the energy and commodity futures markets due to actual and potential disruptions in the supply and demand for certain commodities, including oil and natural gas. The U.S. and other actors have imposed various sanctions and restrictions on business dealings with Russia, which include restrictions on imports of oil, natural gas and coal. It is impossible to predict the effect of current or future sanctions and restrictions, the extent and duration of the conflict, and associated disruptions in the energy sector. The effect of these events or any related developments could be significant and may have a severe adverse effect on a Fund’s performance.

consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The U.K. left the EU (“Brexit”) on January 31, 2020. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.

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

terrorism, strained international relations and territorial disputes. Any of these events may adversely affect the issuers, markets and economies to which a Fund is exposed, which may adversely affect the value of the Fund.

Healthcare Companies Risk. The profitability of healthcare companies may be adversely affected by the following factors, among others: extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, a limited number of products, labor shortages, supply chain issues and industry innovation. Many new products in the healthcare sector entail significant research and development and require regulatory approval, all of which may be long and costly, and such efforts ultimately may be unsuccessful. Many healthcare companies depend heavily on obtaining and defending patents, which can be costly, and may be adversely affected by the expiration of patents. Healthcare companies also are subject to extensive litigation based on product liability and similar claims.

Hedging Risk. When a derivative is used as a hedge against a position that a Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, there can be imperfect matching between the hedging instrument and the hedged investment. Hedging entails additional transaction costs and may result in certain adverse tax consequences. There can be no assurance that a Fund’s hedging strategy will be effective.

Inflation Hedges. There is no guarantee that hedging will completely eliminate the impact of inflation on a Fund’s bond portfolio. An inflation hedging strategy is not intended to mitigate credit risk, interest rate risk, or other factors, which may have a greater impact than inflation on the bonds’ returns. If interest rates fall, but inflation does not, the Fund’s investments will generally underperform a portfolio composed solely of the bonds. Furthermore, a Fund with a hedging strategy may be more volatile than a long-only investment in bonds. There is no guarantee that a Fund will have positive returns, even in times of sharply rising inflation, during which the Fund’s hedging might be expected to mitigate the effects of inflation. Moreover, to the extent that inflation risk has been priced into bonds held by a Fund or Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Interest Rate Hedges. There is no guarantee that hedging will completely eliminate the impact of interest rates on a Fund’s bond portfolio. An interest rate hedging strategy is not intended to mitigate credit risk, inflation risk, or other factors, which may have a greater impact than interest rates on the bonds’ returns. If interest rates fall, long-only bond investments may perform better than the Fund’s investments. Furthermore, a Fund with a hedging strategy may be more volatile than a long-only investment in bonds. There is no guarantee that a Fund will have positive returns, even in times of sharply rising interest rates, during which the Fund’s hedging might be expected to mitigate the effects of such rises.

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

The major risks of high yield securities investments include:

■

High yield securities may be issued by less creditworthy issuers. Issuers of high yield securities may have a larger amount of outstanding debt relative to their assets than issuers of investment-grade bonds. In the event of an issuer’s bankruptcy, claims of other creditors may have priority over the claims of high yield securities holders, leaving few or no assets available to repay high yield securities holders.

■

Prices of high yield securities are subject to extreme price fluctuations. Adverse changes in an issuer’s industry and general economic conditions may have a greater impact on the prices of high yield securities than on other higher rated fixed-income securities. The credit rating of a high yield security does not necessarily address its market value risk. Ratings and market value may change from time to time, positively or negatively, to reflect new developments regarding the issuer.

■

Issuers of high yield securities may be unable to meet their interest or principal payment obligations because of an economic downturn, specific issuer developments, or the unavailability of additional financing.

■

High yield securities frequently have redemption features that permit an issuer to repurchase the security from a Fund before it matures. If the issuer redeems high yield securities held by a Fund, the Fund may have to invest the proceeds in bonds with lower yields and may lose income.

■

High yield securities may be less liquid than higher rated fixed-income securities, even under normal economic conditions. There are fewer dealers in the high yield securities market, and there may be significant differences in the prices quoted for high yield securities by the dealers. Because high yield securities may be less liquid than higher rated fixed-income securities, judgment may play a greater role in valuing certain of a Fund’s securities than is the case with securities trading in a more liquid market.

■

A Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer.

Income Risk. A Fund’s income may decline if interest rates fall. This decline in income can occur because a Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, as bonds in the Underlying Index are substituted, or if the Fund otherwise needs to purchase additional bonds. If a Fund hedges against certain risks (e.g., interest rate risk or inflation risk) but the hedging strategy is not effective, the Fund’s income may fall due to a decline in value of both the securities and the hedging instruments held by the Fund.

Industrial Companies Risk. Industrial companies face a number of risks, including supply chain and distribution disruptions, business interruptions, third-party vendor risks, cyber attacks, trade disputes, product recalls, liability and environmental damage claims, scarcity of materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and currencies. The products of industrial companies may face obsolescence due to technological developments and new product introduction. Furthermore, changes in trade restrictions and tariffs as well as broader geopolitical developments could adversely affect industrial companies. These companies also may be significantly affected by domestic and international economic conditions, legislative and regulatory changes, and labor relations. Industrial companies may depend on public or private sector financing, which may become difficult to obtain due to government spending constraints or reduced availability of capital. Such companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others.

Inflation-Linked Instruments Risk. The returns of CPI swaps and other inflation-linked instruments that may be used by the Fund to hedge inflation risk reflect a specified index of inflation measured by the CPI. There can be no assurance that the CPI or other inflation index used will accurately measure either the actual rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. As a result, the Fund’s inflation-hedging strategy may not perform as expected. CPI swaps may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions. CPI swaps create leverage because they rely on future payments, which may cause the Fund’s NAV and returns to be more volatile than they would be if the Fund had not used swaps. CPI swaps also expose the Fund to counterparty risk, which is the risk that the swap counterparty will not fulfill its contractual obligations. The Fund’s hedging strategy is not customized to particular bonds or investment instruments. As a result, there may be a mismatch between the CPI swaps (and other inflation-linked instruments) and the bonds held by the Underlying Fund that are being hedged. If this were the case, the Fund could lose money on both the inflation hedging instruments and the bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

Inflation Risk. An inflation hedged Fund seeks to mitigate many of the adverse impacts of inflation on bonds held by the Fund or the Underlying Fund and their issuers primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

By entering into a CPI swap, the Fund effectively turns the inflation component of the bonds held by the Fund or the Underlying Fund from fixed rates into floating rates. The Fund will lose money on the CPI swap and underperform if inflation is lower than the expected rate being hedged. The Fund will benefit from a CPI swap if actual inflation (as measured by the CPI) during the time period in which the Fund holds the swap is the same or greater than the level of inflation expected for that period. However, if actual inflation (as measured by the CPI) is less than the rate of inflation expected for that period, the Fund generally will lose money on the CPI swap and underperform the Underlying Fund as a result of having entered into the CPI swap.

Interest Rate Swap Risk. Interest rate swaps consist of an exchange between counterparties of their rights to receive interest payments based on a reference interest rate and typically involve the payment by one counterparty of a fixed rate in respect of a defined notional amount in exchange for receipt of a floating rate on the same notional amount, each having the same payment dates and payable in the same currency. Interest rate swaps are subject to risks applicable to swaps generally, including the risk that a counterparty fails to meet its obligations and the risk that the Fund is not able to liquidate such swap in a timely manner or at all, which could result in losses to the Fund. If a Fund invests in swaps that are subject to central clearing, these swaps are subject to the risk that a central clearinghouse will go into bankruptcy or become non-operational, and sometimes involve increased transaction costs. Counterparties to OTC swaps are not subject to these risks. A Fund’s use of interest rate swaps requires it to post collateral, which may restrict the Fund’s ability to otherwise invest such collateral and involves additional costs to the Fund. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund. Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.

Investment in Underlying Fund Risk. For a Fund that invests in an Underlying Fund, the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Fund. A Fund’s NAV will change with changes in the value of an Underlying Fund and other assets that the Fund holds. The shares of an Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in a Fund that invests in an Underlying Fund will indirectly bear the expenses charged by the Underlying Fund, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Fund (except to the extent that certain fees are waived by BFA). An investor in such a Fund may receive taxable gains from portfolio transactions by an Underlying Fund, as well as taxable gains from transactions in the shares of an Underlying Fund that are held by the Fund.

closing time. As a result, during the time when the exchange is open but after the applicable market closing, fixing or settlement time, there may be wider bid/ask spreads on the exchange and a greater premium or discount to NAV.

Media Sub-Industry Risk. Companies in the media sub-industry may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Media companies are subject to risks that include cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, competition in the industry and the potential for increased state and federal regulation. Advertising spending is an important source of revenue for media companies. During economic downturns advertising spending typically decreases and as a result, media companies tend to generate less revenue.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. To the extent that a Fund makes investments in a limited number of countries, events in those countries will have a more significant impact on the Fund. The risks of investing in non-U.S. securities include the following, any of which may have an adverse impact on a Fund:

■

Less liquid markets, which may make valuing securities more difficult;

■

Greater market volatility;

■

Government intervention in issuers' operations or structure;

■

Government expropriation or nationalization of assets;

■

Exchange rate fluctuations and exchange controls;

■

Limitations on foreign ownership of securities;

■

Imposition of withholding or other taxes;

■

Restrictions on the repatriation of capital;

■

Higher transaction and custody costs;

■

Foreign market trading hours, different clearing and settlement procedures, and holiday schedules, which may limit a Fund's ability to engage in portfolio transactions;

■

Less regulation of the securities and other financial markets;

■

Less availability of public information about issuers;

■

Weaker accounting, audit, disclosure and financial reporting requirements and the risk of being delisted from U.S. exchanges;

■

Difficulties in enforcing contractual obligations; and

■

Legal principals relating to corporate governance, directors’ fiduciary duties and liabilities, and shareholder rights that are less robust than those that apply in the U.S.

voted by BFA and its affiliates for client funds and accounts managed by BFA (including a Fund) may not exceed the relevant limits without the grant of a license or other regulatory or corporate approval, order, consent, relief or non-disapproval. However, there is no guarantee that permission will be granted or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. In other cases, exceeding such thresholds may cause BFA and its affiliates, a Fund or other client accounts to suffer disadvantages or business restrictions.

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

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

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

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject a Fund to risks specific to China. The Chinese economy is subject to a considerable degree of economic, political and social instability.

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

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. However, government control over certain sectors or enterprises and significant regulation of investment and industry is still pervasive, including restrictions on investment in companies or industries deemed to be sensitive to particular national interests, trading of securities of Chinese issuers, foreign ownership of Chinese corporations and/or the repatriation of assets by foreign investors. Limitations or restrictions on foreign ownership of securities may have adverse effects on the liquidity and performance of a Fund and, for a Fund that tracks an Underlying Index, could lead to higher tracking error. Chinese government intervention in the market may have a negative impact on market sentiment, which may in turn affect the performance of the Chinese economy and a Fund’s investments. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, lack of publicly available

information, and political and social instability. Chinese companies, such as those in the financial services or technology sectors, and potentially other sectors are also subject to the risk that Chinese authorities can intervene in their operations and structure, which may negatively affect the value of a Fund’s investments.

Economic Risk. The Chinese economy may be adversely affected by, among other things, a deterioration in global demand for Chinese exports or a contraction in spending on domestic goods by Chinese consumers. In addition, China may experience substantial rates of inflation, significant indebtedness or economic recessions, which would have a negative effect on its economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered the performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates.

A reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs, sanctions or other trade barriers (including as a result of heightened trade tensions between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy and companies in which a Fund invests. Certain Chinese companies (which may change from time to time) are directly or indirectly subject to economic or trade restrictions imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. For example, certain foreign technology companies are subject to U.S. export controls as those companies are believed to pose a risk to U.S. interests. The U.S. also bans imports of goods produced in certain regions of China or by certain Chinese companies due to concerns about forced labor. Such restrictions may have unanticipated and adverse effects on the Chinese economy and companies. Any action that targets Chinese financial markets or securities exchanges could interfere with orderly trading, delay settlement or cause market disruptions. For a Fund that tracks an Underlying Index, the index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments. So long as these restrictions do not include restrictions on investments, such Fund is generally expected to invest in such companies, consistent with its objective to track the performance of the Underlying Index.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking, and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Security Risk. China has strained international relations with Taiwan, Japan, India, Russia and other neighbors due to territorial disputes, historical animosities, defense concerns and other security concerns. China has a complex territorial dispute regarding the sovereignty of Taiwan and has pledged to take control of Taiwan, including by force if necessary. The Chinese military has conducted military drills around Taiwan in connection with China’s claim to Taiwan. Taiwan-based companies and individuals are significant investors in China. These tensions between Taiwan and China may adversely affect the Chinese economy. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which a Fund invests. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy. Such risks, among others, may adversely affect the value of a Fund’s investments.

Chinese Equity Markets. There are several types of Chinese securities: H-shares, A-shares, B-shares, Red-Chips and P-Chips. The issuance of B-shares and H-shares by Chinese companies and the ability to obtain a “back-door listing” through Red-Chips or P-Chips is still regarded by the Chinese authorities as an experiment in economic reform. “Back-door listing” is a means by which a mainland Chinese company issues Red-Chips or P-Chips to obtain quick access to international listing and international capital. These share mechanisms are subject to the political and economic policies in China. In addition, some Chinese companies are listed on U.S. exchanges, such as through American Depositary Receipts (“ADRs”) or variable interest entities (“VIEs”), which are subject to the investment risks associated with the underlying Chinese issuer or operating company. Instead of directly owning the equity securities of a Chinese company, a VIE enters into service contracts and other contracts with the Chinese company, which provide the VIE with exposure to the company. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company’s performance and the enforceability of the VIE’s contractual arrangements with the Chinese company.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (“SAR”) of the People’s Republic of China (“PRC”) under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Since 1997, there have been tensions between the Chinese government and many people in Hong Kong who perceive China as tightening control over Hong Kong’s semi-autonomous liberal political, economic, legal and social framework. Recent protests and unrest have increased tensions even further. Due to the interconnected nature of the Hong Kong and Chinese economies, this instability in Hong Kong may cause uncertainty in the Hong Kong and Chinese markets. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because a Fund’s NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in a Fund’s NAV.

Limited Information and Legal Remedies. Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about Chinese securities in which a Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies.

Risk of Investing in the China Bond Market. A Fund’s investment in the China Interbank Bond Market occurs through the Bond Connect trading channel, which allows eligible foreign investors to trade electronically between the mainland China and Hong Kong markets. Bonds traded through Bond Connect are settled and custodied through a link between CMU, as an offshore custody agent, and China Central Depository & Clearing (“CCDC”) and Shanghai Clearing House (“SCH”), as onshore custodians and clearing institutions in the PRC. All bonds traded by eligible foreign investors through Bond Connect are registered in the name of CMU, which holds such bonds as a nominee owner. A Fund is thus exposed to custody risks with respect to CMU. In addition, the relevant filings, registration with the People’s Bank of China, and account opening must be carried out by third parties, including CMU, CCDC, and SCH. A Fund is thus subject to the risks of default, errors and omissions by such third parties and may have limited remedies or no legal recourse at all to cure any defaults, errors and omissions.

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

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

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

There is no assurance that Bond Connect trading platforms and operational systems will function as expected or will continue to be adapted to changes and developments in the market. If a relevant system does not function as expected, trading through Bond Connect may be disrupted, and a Fund’s ability to pursue its investment strategy may therefore be adversely affected. In addition, trading through Bond Connect involves the risk of delays inherent in order placing and settlement systems.

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

Under prevailing tax regulations, a 10% withholding tax is imposed on PRC-sourced dividends and interest from non-government bonds paid to a Fund unless the rate is reduced under an applicable tax treaty. Value added tax (“VAT”) is levied on certain income derived by a Fund, including interest income from non-government bonds and trading gains, unless specifically exempted by the PRC tax authorities. VAT exemptions currently apply to debt securities traded in the China Interbank Bond Market. On November 22, 2018, the PRC’s Ministry of Finance and State Administration of Taxation jointly issued Circular 108 providing foreign institutional investors with a temporary exemption from withholding income tax and VAT with respect to interest income derived from non-government bonds in the domestic bond market for the period from November 7, 2018 to November 6, 2021. On November 26, 2021, the PRC's Ministry of Finance and State Administration of Taxation jointly issued Circular 34 to extend the tax exemption period provided in Circular 108 to December 31, 2025. Circular 108 is silent on the PRC tax treatment with respect to non-government bond interest derived prior to November 7, 2018. There is a risk the PRC tax authorities may withdraw the temporary tax exemptions and seek to collect withholding income tax and VAT on interest income from non-government bonds to a Fund without prior notice. If the tax exemptions are withdrawn, any taxes arising from or to a Fund may be directly borne by, or indirectly passed on to, the Fund, which may substantially impact its NAV. As with any NAV adjustment, investors may be advantaged or disadvantaged depending on when the investors purchased or sold shares of the Fund. Any changes in PRC tax law, future

clarifications thereof, and/or subsequent retroactive enforcement by the PRC tax authorities may result in a loss that could be material to a Fund. BFA will keep the provisioning policy for tax liability under review and may, in its discretion from time to time, make a provision for potential tax liabilities if in its opinion such provision is warranted or as further publicly clarified by the PRC.

Risk of Investing in Developed Countries. Investment in developed country issuers will subject a Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which a Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which a Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in Emerging Markets. Investments in emerging market issuers are subject to a greater risk of loss than investments in issuers located or operating in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, social, political or economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets.

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

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

Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Fund invests may be less reliable or complete. Moreover, emerging markets often have less reliable securities valuations and greater risks associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. A Fund does not select investments based on investor protection considerations.

In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Chronic structural public sector deficits in some countries in which a Fund may invest may adversely impact securities held by the Fund.

Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to changes in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. (and other developed countries). In addition, significant delays may occur in certain markets in registering the transfer of securities. Settlement or registration problems may make it more difficult for a Fund to value its portfolio securities and could have an adverse effect on the Fund in seeking to achieve its investment objective.

Investing in emerging market countries involves a higher risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested in certain emerging market countries. As a result, investments in certain countries in which a Fund may invest may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Risk of Investing in Saudi Arabia. Investing in Saudi Arabian issuers involves legal, regulatory, political, currency, security, and economic risks that are specific to Saudi Arabia. Saudi Arabia is highly reliant on income from the sale of petroleum and trade with other countries involved in the sale of petroleum, and its economy is therefore vulnerable to changes in foreign currency values and the petroleum market. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. In addition, Saudi Arabia’s economy relies heavily on cheap, foreign labor, and changes in the availability of this labor supply could have an adverse effect on the economy.

Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of a Fund’s investments. Such heightened risks may include, among others, the expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, crime and instability

as a result of religious, ethnic and/or socioeconomic unrest. The government of Saudi Arabia exercises substantial influence over many aspects of the private sector, and its actions could significantly impact the value of Saudi Arabian securities. Although some economic reforms (e.g., privatization) are underway, restrictions on foreign ownership persist, and the government has an ownership stake in many key industries. Saudi Arabia has experienced strained relations with economic partners worldwide, including other countries in the Middle East, due to geopolitical events. Economic sanctions (or the threat of them) on Saudi Arabian individuals or Saudi Arabian corporate entities may have an adverse impact on the Saudi Arabian economy and securities.

The ability of foreign investors to invest in the securities of Saudi Arabian issuers could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership of such securities. In addition, the Saudi Arabian government places investment limitations on the ownership of Saudi Arabian issuers by foreign investors. Such limits may prevent a Fund from investing in accordance with its strategy and result in tracking error for a Fund that tracks an index.

Saudi Arabia Broker Risk. There are a number of ways to conduct transactions in equity securities in the Saudi Arabian market. A Fund generally expects to transact in a manner so that it is not limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to a Fund, which may have an adverse impact on the prices, quantity or timing of Fund transactions. A limited number of brokers may impact a Fund’s ability to achieve best execution on transactions. In addition, a Fund may be more susceptible to credit loss or trading disruptions in the event of a default or business disruption among the available brokers. If a Fund’s use of a broker is disrupted, there could be an adverse impact on the Fund’s operations and, if applicable, its ability to track the Underlying Index, and the Fund’s shares could trade at a premium or discount to NAV. A Fund may also incur losses due to the acts or omissions of its brokers in the execution or settlement of transactions or in the transfer of funds or securities.

Tax Risk. The federal income tax treatment of a Fund’s investment in a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income that a Fund realizes from its investments. As a result, a larger portion of a Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by a Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the IRS.

For a Fund that invests in an Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and will not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may

result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Technology Companies Risk. Technology companies and companies that rely heavily on technological advances may have limited product lines, markets, financial resources and personnel. These companies may face rapid product obsolescence as well as unexpected risks and costs related to new product introduction and technological developments, such as artificial intelligence and machine learning. Technology companies may be adversely affected by disruptions to supply chains and distribution networks as well as issues at third-party partners. They are heavily dependent on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect their profitability. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action. These companies also may be adversely affected by, among other things, actual or perceived security vulnerabilities or other defects in their products and services, which may result in lawsuits, government enforcement actions and other remediation costs.

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

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

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

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

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

Certain Underlying Funds seek to obtain exposure to the fixed-rate portion of U.S. agency mortgage pass-through securities primarily through TBA securities, or TBA transactions. TBAs refer to a commonly used mechanism for the forward settlement of U.S. agency MBS, and

not to a separate type of MBS. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to possible losses because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction.

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

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances (e.g., reaching the legislative “debt ceiling”) could arise that could prevent the timely payment of interest or principal. An actual or threatened failure of the U.S. government to pay its obligations would result in losses to a Fund holding such securities as well as substantial negative consequences for the U.S. economy and the global financial system.

A high national debt level may increase market pressures to meet government funding needs, which may drive debt costs higher and lead the government to issue additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that the U.S. government will not be able to make principal or interest payments when they are due. If market participants determine that U.S. sovereign debt levels are unsustainable, the value of the U.S. dollar could decline, thus increasing inflationary pressures and constraining the U.S. government’s ability to implement effective countercyclical fiscal policy in economic downturns.

Utility Companies Risk. Utility infrastructure often requires significant capital expenditures, and utility companies may face high interest costs and difficulty in raising capital. Technological innovations may render existing equipment or products obsolete, and companies may experience difficulty in obtaining regulatory approval of new technologies. Utility operations may be disrupted by events that target or damage utility infrastructure, including natural disasters and cyber or other attacks. Utilities companies may be adversely affected by volatility in the price of certain energy resources.

Utility companies face risks from government regulation and oversight as well as from deregulation (if applicable). Regulators may monitor and control companies’ revenues and costs. There is no assurance that regulators will grant rate increases or that rate levels will be adequate to permit the payment of stock dividends or bond coupon payments. In addition, there may be regulatory restrictions on the ability of utility companies to enter new lines of business and geographic areas. Utility companies incur costs in complying with environmental and other regulations and may face significant challenges in obtaining regulatory approval for certain projects, such as nuclear power plants. Utility companies are at risk of liability for environmental harm and other types of damages. Energy conservation, climate change and other sustainability policies also may impact utility companies. Deregulation may subject companies to greater competition, may adversely affect their profitability and may lead them to engage in riskier ventures.

Householding

Distribution

technology platforms and reporting systems, data provision services, or their making shares of the Funds available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Funds. Rather, such payments are made by BFA or its affiliates from their own resources, which come directly or indirectly in part from fees paid by the Funds. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments or other financial incentives the intermediary is eligible to receive. Therefore, such payments or other financial incentives that are offered or made to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Funds over another investment. More information regarding these payments is contained in the applicable SAI. Please contact your salesperson or other investment professional for more information regarding any such payments that their firm may receive from BFA or its affiliates.

Fund	Ticker	Listing Exchange
iShares Bloomberg Roll Select Commodity Strategy ETF (the “Fund”)	CMDY	NYSE Arca

Capitalized terms used herein that are not defined have the same meaning as in the Prospectus, unless otherwise noted. The Financial Statements and Notes contained in the Annual Report and Semi-Annual Report of the Trust for the Fund are incorporated by reference into and are deemed to be part of this SAI.

References to the Investment Company Act of 1940, as amended (the “Investment Company Act” or the “1940 Act”), or other applicable law, will include any rules promulgated thereunder and any guidance, interpretations or modifications by the Securities and Exchange Commission (the “SEC”), SEC staff or other authority with appropriate jurisdiction, including court interpretations, and exemptive, no action or other relief or permission from the SEC, SEC staff or other authority.

iShares® and BlackRock® are registered trademarks of BlackRock Fund Advisors and its affiliates.

General Description of the Trust and the Fund

The Trust currently consists of 16 investment series or portfolios. The Trust was organized as a Delaware statutory trust on June 21, 2011 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the SEC under the 1940 Act. The offering of the Trust's shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates solely to the Fund.

The Fund is managed by BlackRock Fund Advisors (“BFA”), an indirect wholly-owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the specific benchmark index identified in the Fund's Prospectus (the “Underlying Index”).

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a designated portfolio of securities, assets or other positions (including any portion of such securities for which cash may be substituted) (the “Deposit Securities” or “Creation Basket”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca” or the “Listing Exchange”), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Amount (as defined in the Creation and Redemption of Creation Units-Role of the Authorized Participant section of this SAI). Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

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

Exchange Listing and Trading

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

Shares of the Fund are listed for trading, and trade throughout the day, on the Listing Exchange and in other secondary markets. Shares of the Fund may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 record and/or beneficial owners of shares of the Fund; (ii) the Fund is no longer eligible to operate in reliance on Rule 6c-11 under the Investment Company Act; (iii) any of the other listing requirements are not continuously maintained; or (iv) any event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of the Fund from listing and trading upon termination of the Fund.

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

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

Investment Strategies and Risks

The Fund seeks to track the investment results of the Underlying Index, which measures the performance of 24 futures contracts across 19 physical agricultural, energy, precious metals and industrial metals commodities. The Fund operates as an index fund and is not actively managed. Adverse performance of an instrument in the Fund's portfolio will ordinarily not result in the elimination of the instrument from the Fund's portfolio.

In seeking to achieve its investment objective, the Fund will primarily invest in exchange-traded futures contracts (“Index Futures”) on the Underlying Index, and is expected to roll out of existing positions in Index Futures and establish new positions in Index Futures on an ongoing basis. If the price for the new futures contract is less than the price of the expiring contract, then the market for the commodity is said to be in “backwardation.” In these markets, roll returns are positive, which is referred to as “positive carry.” The term “contango” is used to describe a market in which the price for a new futures contract is more than the price of the expiring contract. In these markets, roll returns are negative, which is referred to as “negative carry.” The Underlying Index seeks to employ a positive carry strategy that emphasizes commodities and futures contract months with the greatest degree of backwardation and lowest degree of contango, resulting in net gains through positive roll returns. Index Futures subsequently acquired by the Fund may have terms that differ from those of the Index Futures it currently holds and the purchase and sale of these Index Futures may incur transaction fees. The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in futures contracts through a cash management strategy consisting of investments in cash and cash equivalents, short-term government obligations and short-term investment grade fixed-income securities (collectively, “Fixed-Income Investments”).

The Fund engages in representative sampling, which is investing in a sample of securities and/or other instruments selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities and/or other instruments selected have aggregate investment characteristics (based on market capitalization value and industry weightings), fundamental characteristics (such as yield, credit rating, maturity and duration) and liquidity measures similar to those of the Fund's Underlying Index. A fund that uses representative sampling generally does not hold all of the securities and/or other instruments that are in its underlying index.

The Fund will invest in financial instruments providing exposure to commodities and not in the physical commodities themselves. The Fund may also invest in exchange-traded commodity futures contracts similar to those found in the Underlying Index, as well as swaps and options on futures that correlate to the investment returns of commodities without investing directly in physical commodities and over-the-counter (“OTC”) commodity-linked instruments like commodity-linked notes, swaps and forward contracts (together, the “Commodity Investments”). Investing in derivative contracts may have a leveraging effect on the Fund. Although the Fund may hold the same futures contracts under the same futures rolling schedule as those included in the Underlying Index, the Fund is not obligated to invest in any futures contracts included in, and does not seek to replicate the performance of, the Underlying Index.

The Fund seeks to gain exposure to Index Futures and other Commodity Investments by investing through a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Subsidiary invests solely in Commodity Investments and cash and cash equivalents. In compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity Investments held in the Subsidiary are intended to provide the Fund with exposure to broad commodities consistent with current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity Investments.

The remainder of the Fund’s assets will be invested directly by the Fund, primarily in Fixed-Income Investments, including repurchase agreements, money market instruments, U.S. government and agency securities, Treasury inflation-protected securities, sovereign debt obligations on non-U.S. countries and investment-grade corporate bonds. The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s investments in derivatives.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject registered investment companies and their advisers to regulation by the CFTC if a registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if a registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of CFTC-regulated futures, options and swaps above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”). Although the Fund does not seek leveraged returns, certain instruments used by the Fund may have a leveraging effect as described below.

Investments in the Subsidiary are expected to provide the Fund with exposure to investment returns of commodities within the limitations of Subchapter M of the Internal Revenue Code, as discussed below. The Subsidiary is a company organized under the laws of the Cayman Islands, whose registered office is located at the offices of Maples Corporate Services Limited, P.O. Box 309, Ugland House, Grand Cayman KYI-1104, Cayman Islands. The Subsidiary’s affairs are overseen by a board of directors, which is comprised of Shannon Ghia, Secretary of the Trust, and Rachel Aguirre, Assistant Secretary of the Trust. The Fund is the sole shareholder of the Subsidiary, and shares of the Subsidiary will not be sold or offered to other investors.

The Fund will gain exposure to the investment returns of commodities indirectly by investing in the Subsidiary. To the extent that BlackRock believes that such instruments provide suitable exposure to commodities, the Fund’s investment in the Subsidiary will likely increase. BlackRock manages the assets of the Subsidiary, but receives no additional compensation for doing so.

BlackRock also provides certain administrative services for the Subsidiary, but receives no additional compensation for doing so. The Subsidiary has entered into a contract for the provision of custody, transfer agency, and accounting agent services with the same or with affiliates of the same service providers that provide those services to the Fund.

Generally, the Fund and the Subsidiary test for compliance with investment policies and restrictions, including asset segregation requirements, on a consolidated basis for 1940 Act purposes, calculated in accordance with SEC staff guidance, where applicable. For compliance with federal income tax requirements, the Fund and the Subsidiary expect to comply with the asset segregation requirements on a stand-alone basis, with instruments requiring physical settlement being classified on a market value rather than on a notional basis. The Subsidiary is also expected to comply with the other applicable 1940 Act requirements, including those related to custody and affiliated transactions.

The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in the Fund’s Prospectus or this SAI, is not subject to the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are managed by BFA. The Trust’s Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. As noted above, the Subsidiary will be subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. Changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in the Fund's Prospectus and this SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

The Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a regulated investment company (“RIC”) for U.S. federal income tax purposes. Based on final regulations issued by the U.S. Internal Revenue Service (“IRS”) on which taxpayers may rely for taxable years beginning after September 28, 2016, the Fund expects its income with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues regulations or other guidance , or Congress enacts legislation, limiting the circumstances in which the Fund’s income with respect to the Subsidiary will be considered “qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances.

Moreover, changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or Subsidiary to operate as described in the Fund’s Prospectus and this SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

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

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

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

Derivatives. The Fund will use instruments referred to as derivatives. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), a currency or an index (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). Derivatives allow the Fund to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. The Fund may use derivatives for hedging purposes. The Fund may also use derivatives for speculative purposes to seek to enhance returns or as a vehicle to obtain investment exposure to a security, commodity, currency, or index. The use of a derivative is speculative if the Fund is primarily seeking to achieve gains, rather than to offset the risk of other positions. When the Fund invests in a derivative for speculative purposes, the Fund will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. Unless otherwise permitted, the Fund may not use any derivatives to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly.

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

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

Futures and Options. The Fund may invest in options and futures. The Fund may also purchase call options or write put options. A call option gives a holder the right to purchase a specific security or asset at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security or asset at an exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised.

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

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

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

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), foreign exchange risk (i.e., the risk of a shortfall at default when a cash collateral investment is denominated in a currency other than the currency of the assets being loaned due to movements in foreign exchange rates), and credit, legal, counterparty and market risks (including the risk that market events, including but not limited to corporate actions, could lead the Fund to lend securities that are trading at a premium due to increased demand, or to recall loaned securities or to lend less or not at all, which could lead to reduced securities lending revenue). If the Fund were to lend out securities that are subject to a corporate action and commit to the borrower a particular election as determined by the Fund's investment adviser, the benefit the Fund would receive in respect of committing to such election may or may not be less than the benefit the Fund would have received from making a different election in such corporate action. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s securities as agreed, the Fund’s ability to participate in a corporate action event may be impacted, or the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This latter event could trigger adverse tax consequences for the Fund. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments received by the Fund representing dividends paid on securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income. There could also be changes in the status of issuers under applicable laws and regulations, including tax regulations, that may impact the regulatory or tax treatment of loaned securities and could, for example, result in a delay in the payment of dividend equivalent payments owed to the Fund (as permitted by applicable law).

Regulations adopted by global prudential regulators require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many securities lending agreements, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such agreements, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Fund’s ability to terminate existing securities lending agreements or to realize amounts to be received under such agreements. Prudential regulation may also favor lenders that can provide additional protections, such as liens that are exercisable in connection with a lender default, to borrowers. The Fund may provide additional protections to borrowers, where permitted pursuant to the Fund’s investment policies and if BFA believes doing so is in the best interest of the Fund.

investment,” “less liquid investment” or “illiquid investment.” The Liquidity Rule defines “liquidity risk” as the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of the remaining investors’ interest in the Fund. The liquidity of the Fund's portfolio investments is determined based on relevant market, trading and investment-specific considerations under the Liquidity Program. There are exclusions from certain portions of the liquidity risk management program requirements for “in-kind” ETFs, as defined in the Liquidity Rule. To the extent that an investment is deemed to be an illiquid investment or a less liquid investment, the Fund can expect to be exposed to greater liquidity risk.

Options on Futures Contracts. The Fund may invest in options on futures contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per share, also known as the “strike price,” less the premium received from writing the put.

Privately Issued Securities. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the 1933 Act (“Restricted Securities”). Restricted Securities are not publicly-traded and are subject to a variety of restrictions, which limit a purchaser's ability to acquire or resell such securities. Accordingly, the liquidity of the market for specific Restricted Securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”) or (ii) markets itself as providing investment exposure to such instruments. Due to the Fund's potential use of CFTC Derivatives above the prescribed levels, the Fund and the Subsidiary will each be considered a “commodity pool” under the CEA. Accordingly, BFA, the Fund’s investment adviser, has registered as a commodity pool operator and is subject to CFTC regulation with respect to the Fund. BFA is also subject to regulation by the National Futures Association.

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

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

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

Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”).

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

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

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

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

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

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and the Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of the Fund’s assets. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by the Fund through reverse repurchase agreements may be invested in additional securities.

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

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

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

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

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

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus.

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

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

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

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

things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions, including droughts and floods; livestock disease; changing supply and demand relationships and levels of domestic production and imported commodities; changes in storage costs; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; and changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted. However, it is likely that current declines in trade relations between the U.S. and other countries and tariffs imposed by the U.S. on foreign products and by foreign countries on U.S. commodities will impact commodity prices.

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

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

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

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

Commodity Forward Risk. A commodity forward is a customized, non-standardized agreement that obligates one party to buy, and the other party to sell, a specific quantity of an underlying commodity for an agreed-upon price at a future date, usually for physical delivery. Commodity forwards that are settled by a cash payment at maturity are referred to as “non-deliverable forwards.” Because commodity forwards do not trade on a centralized exchange, they are subject to a higher degree of default risk and, depending upon the underlying commodity, may be less liquid than futures contracts on the same referenced commodity. In addition, use of commodity forwards creates risk for the Fund because the contracts require the Fund to take or make delivery of a physical commodity, which involves additional cost as well as delivery risk. Unless the Fund were to close out a contract prior to maturity, any failure of the Fund to comply with the contract delivery obligations at maturity would cause the Fund to default, which could have adverse collateral consequences for investors.

and dramatically and may or may not correlate to price movements in other asset classes, such as stocks, bonds and cash. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop. Commodity derivatives are subject to the risk that the counterparty to the transaction may default or otherwise fail to perform. The Fund’s use of commodity-linked derivatives can result in large amounts of financial leverage. Although the Fund will not borrow money in order to increase the amount of its trading, the low margin deposits normally required in futures trading permit a high degree of leverage on the investment itself. Accordingly, a relatively small price movement in a futures contract may result in immediate and substantial losses to the Fund. Like other leveraged investments, any trade may result in losses in excess of the amount invested. These factors and events could have a significant negative impact on the Fund.

Currency Risk. Because the Fund's NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases. Generally, when the U.S. dollar rises in value against a foreign currency, a security denominated in that currency loses value because the currency is worth fewer U.S. dollars. Conversely, when the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency gains value because the currency is worth more U.S. dollars. This risk, generally known as “currency risk,” means that a strong U.S. dollar will reduce returns for U.S. investors, while a weak U.S. dollar will increase those returns.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the Fund’s performance and may lower the Fund’s return. The Fund could experience losses if the value of its currency positions are poorly correlated with its other investments or if it cannot close out its positions because of an illiquid market. In addition, the Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

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

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may adversely affect the economies of many nations and the global economy and may impact individual issuers and capital markets in ways that cannot be foreseen. An infectious illness outbreak may result in travel restrictions, closed international borders, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, temporary and permanent business closures, lower consumer demand, layoffs, ratings downgrades, credit defaults and other significant economic, social and political impacts, as well as general concern and uncertainty. An outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. These impacts, which could adversely affect a Fund and its investments, could be present for an extended period of time.

In addition, markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect a Fund and its investments and may impact a Fund’s ability to purchase or sell securities or other assets. Market or economic disruptions could cause elevated tracking error and increased premiums or discounts to a Fund's NAV. Additionally, a Fund could be adversely impacted if an outbreak impairs the operations of its service providers, including BFA. Governmental and quasi-governmental may respond to an outbreak and any resulting disruptions with a variety of fiscal and monetary policy changes, such as changes in interest rates. A reversal of these policies, or the ineffectiveness of such policies, is likely to increase market volatility, which could adversely affect a Fund’s investments.

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

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

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

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

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

fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage.

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

Risk of Futures and Options on Futures Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While the Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to deliver the instruments underlying the futures contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered bond index futures contracts) is potentially unlimited. The Fund does not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit.

Utilization of futures and options on futures by the Fund involves the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

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

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

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

Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. Swaps entered into by the Fund through its Subsidiary are not expected to be centrally cleared and thus will expose the Fund to counter-party default risk and illiquidity risk, as liquidity depends on the willingness of counterparties to enter into, and the ability of counterparties to hedge the risks of, such contracts.

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

A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and lead the government to issue additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that the U.S. government will not be able to make principal or interest payments when they are due. If market participants determine that U.S. sovereign debt levels have become unsustainable, the value of the U.S. dollar could decline, thus increasing inflationary pressures, particularly with respect to services outsourced to non-U.S. providers and imported goods and constrain or prevent the U.S. government from implementing effective countercyclical fiscal policy in economic downturns. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period that shareholders own shares of the Fund. Notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the U.S., circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative “debt ceiling.” Such non-payment would result in losses to the Fund and substantial negative consequences for the U.S. economy and the global financial system.

Valuation Risk. In certain circumstances, the Fund’s securities may be valued using techniques other than market quotations. The value established for a security may be different from what would be produced through the use of another methodology or if the value had been priced using market quotations. Securities that are valued using methods other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a security for the value established for it at any time, and it is possible that the Fund could incur a loss if a security is sold for less than its established value.

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

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

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

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

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

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

Risk of Investing in the Energy Sector. The energy sector is strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation efforts, technological change, development of alternative energy sources, and other factors that they cannot control. These companies may also lack resources and have limited business lines.The energy sector is cyclical and is highly dependent on commodity prices; prices and supplies of energy may fluctuate significantly over short and long periods of time due to, among other things, national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. Commodity prices have recently been subject to increased volatility and declines, which may negatively affect energy-related commodities in which the Fund invests. For example, in the context of the COVID-19 outbreak and disputes among oil-producing countries regarding potential limits on the production of crude oil, the energy sector has experienced increased volatility. In particular, significant market volatility occurred in the crude oil markets as well as the oil futures markets, which resulted in the market price of the front month futures contract falling below zero for a period of time.

The value of securities in the energy sector and energy-related commodities may be adversely affected by terrorism, natural disasters or other catastrophes. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. Significant oil and gas deposits are located in emerging markets countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. Additionally, the Middle East, where much of the energy sector operates, has historically and recently experienced widespread social unrest. The energy sector is highly regulated. Entities operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by governmental agencies. Such regulation can change rapidly or over time in both scope and intensity. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may materially adversely affect the financial performance of companies in the energy sector and energy-related commodities.

Risk of Investing in Gold. The Fund’s portfolio may be adversely affected by changes or trends in the price of gold. Exposure to the gold market may subject the Fund to greater volatility than investments in traditional securities. The price of gold and of gold-related instruments historically has been volatile. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings.

Factors that may cause a change in the price of gold, include, among other things:

•

The strength of the U.S. dollar. Because the price of gold is generally inversely related to the value of the U.S. dollar, a stronger U.S. dollar tends to keep the price of gold lower and more controlled, while a weaker U.S. dollar is likely to drive the price of gold higher. During times of economic uncertainty and when the dollar is weak, investments in gold tend to increase.

•

Large sales, including those by governments, central banks and related institutions, which own a significant portion of the aggregate world holdings in gold. If one or more of these institutions decide to sell in amounts large enough to cause a decline in world gold prices, the performance of the Fund may be adversely affected.

•

Changes in the supply and demand of goods or services of large users of gold. For example, as demand for consumer goods such as jewelry and electronics increases, the price of gold can rise.

•

A significant increase in gold hedging activity by gold producers. Should there be an increase in the level of hedge activity of gold producing companies, it could cause a decline in world gold prices, negatively affecting the performance of the Fund.

•

A significant change in the attitude of speculators and investors towards gold. Should the speculative community take a negative view towards gold, it could cause a decline in world gold prices, negatively affecting the performance of the Fund.

The frequency and magnitude of such changes cannot be predicted.

Certain factors may trigger a temporary increase in the price of gold. If that is the case, the Fund may be investing in securities at prices affected by the temporarily high prices of gold and may incur losses when the causes for the temporary increase disappear.

The commodity markets generally are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions.

Proxy Voting Policies

The Board has delegated the voting of proxies for each Fund’s securities to BFA pursuant to (i) the Open-End Active and Fixed Income Index Fund Proxy Voting Policy (the “Active Fund Proxy Voting Policy”), with respect to certain Funds, and (ii) the Index Equity Fund Proxy Voting Policy, with respect to certain other Funds, as applicable. Please refer to the table below, which discloses the policy applicable to each Fund in this SAI. Information that does not apply to a Fund does not form a part of that Fund’s SAI and should not be relied on by investors in that Fund. Only information that is clearly identified as applicable to a Fund is considered to form a part of that Fund’s SAI.

With respect to Funds covered by the Active Fund Proxy Voting Policy, BFA has adopted the BlackRock Active Investment Stewardship - Global Engagement and Voting Guidelines (the “BAIS Guidelines”). Certain of such Funds, as listed within the Active Fund Proxy Voting Policy and as disclosed in the table below, follow supplemental guidelines within the BAIS Guidelines that are applicable to certain climate and decarbonization issues (the “BAIS Climate and Decarbonization Stewardship Guidelines”).

With respect to Funds covered by the Index Equity Fund Proxy Voting Policy, BFA has adopted the BlackRock Investment Stewardship (“BIS”) Global Benchmark Policy, comprised of the Global Principles for Benchmark Policies, regional voting guidelines, and engagement priorities, which are each available upon request. In addition, certain of such Funds, as listed within the Index Equity Fund Proxy Voting Policy and as disclosed in the table below, follow supplemental guidelines that are applicable to certain climate and decarbonization issues (the “BIS Climate and Decarbonization Stewardship Guidelines”).

iShares Bloomberg Roll Select Commodity Strategy ETF*	X

Policy is effective on January 1, 2025.

If a Fund invests in an underlying fund managed by BlackRock, the Fund will use its proxy voting policy when voting on proxies for the underlying fund while the underlying fund will use its proxy voting policy when voting proxies on investments the underlying fund holds. Therefore, the Fund may use the Active Fund Proxy Voting Policy while an underlying fund may use the Index Equity Fund Proxy Voting Policy, and the opposite is also true.

Copies of the Active Fund Proxy Voting Policy, Index Equity Fund Proxy Voting Policy, the BAIS Guidelines, the Global Principles for Benchmark Policies and the BIS Climate and Decarbonization Stewardship Guidelines are included in Appendix A of this SAI.

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

Portfolio Holdings Information

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

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

•

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

Data File (collectively, “Files”). The Files are applicable for the next trading day and are provided to the NSCC and/or posted on www.iShares.com after the close of markets in the U.S.

•

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

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

•

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

•

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

•

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

•

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

•

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

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

Construction and Maintenance of the Underlying Index

A description of the Fund's Underlying Index is provided below.

With respect to certain underlying indexes of the iShares funds, BFA or its affiliates have held discussions with the applicable index provider regarding their business interest in licensing an index to track a particular market segment and conveyed investment concepts and strategies that could be considered for the index. The index provider designed and constituted such indices using concepts conveyed by BFA or its affiliates. For certain of these indices, the relevant fund may be the first or sole user of the underlying index. In its sole discretion, the index provider determines the composition of the securities and other instruments in such underlying index, the rebalance protocols of the underlying index, the weightings of the securities and other instruments in the underlying index, and any updates to the methodology. From time to time, BFA or its affiliates may

also provide input relating to possible methodology changes of such underlying index pursuant to the index provider’s consultation process or pursuant to other communications with the index provider.

The Bloomberg Roll Select Commodity Total Return Index

Number of Components: approximately 24

The Bloomberg Roll Select Commodity Total Return Index is a variation of the Bloomberg Commodity Index and seeks to mitigate the effects of contango market structure on index performance. The Index consists of 24 futures contracts across 22 physical agricultural, energy, precious metals and industrial metals commodities. The Index is rebalanced annually in January providing a broad-based exposure to commodities as an asset class by using liquidity and world production factors, along with the following diversification rules:

•

No single commodity (e.g., natural gas, silver) may constitute more than 15% of the Index;

•

No single commodity, together with its derivatives (e.g., WTI crude oil and Brent crude oil, together with ULS diesel, Unleaded gas, and Low Sulphur Gas Oil ), may constitute more than 25% of the Index;

•

No related group of commodities (e.g., energy, precious metals, livestock or grains) may constitute more than 33% of the Index;

•

No single commodity (e.g., natural gas, silver) may constitute less than 2% of the Index as liquidity allows.

The Index maintains a long position for each commodity futures contract. On a monthly basis, the Index rolls into a futures contract showing the most backwardation, or least amount of contango, selecting from those eligible contracts with 9 months or fewer until expiration. The Index rolls over 5 business days at 20%, from the 6th to 10th Bloomberg Commodity Index Business Day.

Investment Policies

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

Fundamental Investment Policies

The Fund may not:

Concentrate its investments in a particular industry, as that term is used in the Investment Company Act.

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

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

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

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

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

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

Notations Regarding the Fund's Fundamental Investment Policies

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

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

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund's total assets from banks for any purpose, and to borrow up to 5% of the Fund's total assets from banks or other lenders for temporary purposes. (The Fund's total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with Rule 18f-4 under the Investment Company Act, when the Fund engages in reverse repurchase agreements and similar financing transactions, the Fund may either (i) maintain asset coverage of at least 300% with respect to such transactions and any other borrowings in the aggregate, or (ii) treat such transactions as “derivatives transactions” and comply with Rule 18f-4 with respect to such transactions. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

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

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

Non-Fundamental Investment Policies of the Fund

Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:

Purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) of the Investment Company Act, at any time the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1). The foregoing restriction does not restrict the Fund from acquiring the shares of registered open-end investment companies to the extent otherwise permissible under other provisions of the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.

Notations Regarding the Fund’s Fundamental and Non-Fundamental Investment Policies

Unless otherwise indicated, all limitations under the Fund’s fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment.

Continuous Offering

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

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all of the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

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

A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Fund and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Fund rests with the Board. The Board has engaged BFA to manage the Fund on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Fund in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of eleven members, nine of whom are Independent Trustees. The Board currently conducts regular in person meetings four times a year. In addition, the Board frequently holds special in person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

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

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

Board oversight of risk is also performed as needed between meetings through communications between BFA and the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities. From time to time, the Board may modify the manner in which it conducts risk oversight. The Board’s oversight role does not make it a guarantor of the Fund's investment performance or other activities.

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

The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board and recommends appointments to the Advisory Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Board Chair; (v) periodic review of the Board's retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Board Chair and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nominations recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity). The Nominating and Governance Committee met six times during the fiscal year ended October 31, 2024.

Each Independent Trustee serves on the 15(c) Committee. The Chair of the 15(c) Committee is Richard L. Fagnani. The principal responsibilities of the 15(c) Committee are to support, oversee and organize on behalf of the Board the process for the annual review and renewal of the Trust's advisory and sub-advisory agreements. These responsibilities include: (i) meeting with BlackRock, Inc. in advance of the Board meeting at which the Trust's advisory and sub-advisory agreements are to be considered to discuss generally the process for providing requested information to the Board and the format in which information will be provided; and (ii) considering and discussing with BlackRock, Inc. such other matters and information as may be necessary and appropriate for the Board to evaluate the investment advisory and sub-advisory agreements of the Trust. The 15(c) Committee met two times during the fiscal year ended October 31, 2024.

The members of the Securities Lending Committee are Jane D. Carlin (Chair), James C. Lam, Drew E. Lawton and John E. Martinez, each of whom is an Independent Trustee. The principal responsibilities of the Securities Lending Committee are to support, oversee and organize on behalf of the Board the process for oversight of the Trust's securities lending activities. These responsibilities include: (i) requesting that certain information be provided to the Committee for its review and consideration prior to such information being provided to the Board; (ii) considering and discussing with BlackRock, Inc. such other matters and information as may be necessary and appropriate for the Board to oversee the Trust's securities lending activities and make required findings and approvals; and (iii) providing a recommendation to the Board regarding the annual approval of the Trust's Securities Lending Guidelines and the required findings with respect to, and annual approval of, the Trust's agreement with the securities lending agent. The Securities Lending Committee met six times during the fiscal year ended October 31, 2024.

The members of the Equity Plus Committee are John E. Martinez (Chair), Jane D. Carlin, Richard L. Fagnani, and Cecilia H. Herbert, each of whom is an Independent Trustee. The principal responsibilities of the Equity Plus Committee are to support, oversee and organize on behalf of the Board the process for oversight of Trust performance and related matters for equity

funds. These responsibilities include: (i) reviewing quarterly reports regarding Trust performance, secondary market trading and changes in net assets to identify any matters that should be brought to the attention of the Board; and (ii) considering any performance or investment related matters as may be delegated to the Committee by the Board from time to time and providing a report or recommendation to the Board as appropriate. The Equity Plus Committee met four times during the fiscal year ended October 31, 2024.

The members of the Fixed Income Plus Committee are Drew E. Lawton (Chair), Laura F. Fergerson, James C. Lam and Madhav V. Rajan, each of whom is an Independent Trustee. The principal responsibilities of the Fixed Income Plus Committee are to support, oversee and organize on behalf of the Board the process for oversight of Trust performance and related matters for fixed-income or multi-asset funds. These responsibilities include: (i) reviewing quarterly reports regarding Trust performance, secondary market trading and changes in net assets to identify any matters that should be brought to the attention of the Board; and (ii) considering any performance or investment related matters as may be delegated to the Committee by the Board from time to time and providing a report or recommendation to the Board as appropriate. The Fixed Income Plus Committee met four times during the fiscal year ended October 31, 2024.

The members of the Risk Committee are James C. Lam (Chair), Jane D. Carlin (Co-Chair), Cecila H. Herbert, Drew E. Lawton and Madhav V. Rajan, each of whom is an Independent Trustee.

The Risk Committee commenced on January 1, 2016. The Risk Committee met seven times during the fiscal year ended October 31, 2024.

As the Chair of the Board, John E. Kerrigan may serve as an ex-officio member of each Committee.

Appointed to serve as an Interested Trustee effective March 5, 2024.

Appointed to serve as an Independent Trustee effective April 8, 2024.

As of December 31, 2024, none of the Independent Trustees or their immediate family members owned beneficially or of record any securities of BFA (the Fund's investment adviser), the Distributor or any person controlling, controlled by or under common control with BFA or the Distributor.

Remuneration of Trustees and Advisory Board Members. Effective January 1, 2025, each current Independent Trustee is paid an annual retainer of $475,000 for his or her services as a Board member to the BlackRock-advised Funds in the iShares Complex, together with out-of-pocket expenses in accordance with the Board’s policy on travel and other business expenses relating to attendance at meetings. The annual retainer for services as an Advisory Board Member is the same as the annual retainer for services as a Board member. The Independent Chair of the Board is paid an additional annual retainer of $125,000. The Chair of each of the Audit Committee, Risk Committee, Equity Plus Committee, Fixed Income Plus Committee, Securities Lending Committee, Nominating and Governance Committee and 15(c) Committee is paid an additional annual retainer of $50,000. The Co-Chair of each of the Audit Committee and Risk Committee is paid an additional retainer of $25,000. Each Independent Trustee that served as a director of subsidiaries of the iShares Complex is paid an additional annual retainer of $10,000.

The table below sets forth the compensation paid to each Independent Trustee for services to the Fund and the aggregate compensation paid to them for services to the iShares Complex. Because BFA has agreed in the Investment Advisory Agreements to cover all operating expenses of the Fund, subject to certain exclusions as provided for therein, BFA pays the compensation from its management fees. Compensation from the iShares Complex is not paid to Interested Trustees.

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

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

BlackRock has proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. BlackRock is also a major participant in the global currency, equities, swap and fixed income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, BlackRock is or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests.

Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. In addition, the portfolio holdings of certain BlackRock-advised investment vehicles managed in an identical or substantially similar manner as certain Funds are made publicly available on a more timely basis than the applicable Fund. In some cases, such portfolio holdings are made publicly available on a daily basis. While not expected, it is possible that a recipient of portfolio holdings information for such an investment vehicle could cause harm to a Fund that is managed in an identical or substantially similar manner, including by trading ahead of or against such Fund based on the information received.

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

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) BlackRock or its other accounts or funds, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) BlackRock or its other accounts or funds.

BlackRock, on behalf of other client accounts, on the one hand, and a Fund, on the other hand, may invest in or extend credit to different parts of the capital structure of a single issuer. BlackRock may pursue rights, provide advice or engage in other activities, or refrain from pursuing rights, providing advice or engaging in other activities, on behalf of other clients with respect to an issuer in which a Fund has invested, and such actions (or refraining from action) may have a material adverse effect on the Fund. In situations in which clients of BlackRock (including the Funds) hold positions in multiple parts of the capital structure of an issuer, BlackRock may not pursue certain actions or remedies that may be available to a Fund, as a result of legal and regulatory requirements or otherwise. BlackRock addresses these and other potential conflicts of interest based on the facts and circumstances of particular situations. For example, BlackRock may determine to rely on information barriers between different business units or portfolio management teams. BlackRock may also determine to rely on the actions of similarly situated holders of loans or securities rather than, or in connection with, taking such actions itself on behalf of the Funds.

In addition, to the extent permitted by applicable law, certain Funds may invest their assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and redemptions or sales, and increased remuneration and profitability for BlackRock and/or its personnel, including portfolio managers.

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

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

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

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

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

access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock, or the activities or strategies used for accounts managed by BlackRock or other client accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

The Funds may be included in investment models developed by BlackRock for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Funds, the investment management fee amounts paid by the Funds to BlackRock may also increase. The net asset value and liquidity of a Fund may be impacted by purchases and sales of the Fund by model-driven investment portfolios, as well as by BlackRock itself and by its advisory clients. In addition, certain principals and certain employees of a Fund’s investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their clients may be a consideration of which investors in a Fund should be aware.

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

BlackRock may also create, write or issue derivatives for clients, the underlying securities, currencies or instruments of which may be those in which a Fund invests or which may be based on the performance of the Fund. Additionally, an affiliate of BlackRock will create, write or issue options, which may be based on the performance of certain Funds. BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for underlying fixed-income indexes used by certain iShares ETFs, related to derivative fixed-income products that are based on such iShares ETFs. Trading activity in these derivative products could also potentially lead to greater liquidity for such products, increased purchase activity with respect to these iShares ETFs and increased assets under management for BlackRock. A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock and may also enter into transactions with other clients of BlackRock where such other clients have interests adverse to those of the Fund. At times, these activities may cause business units or entities within BlackRock to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent such transactions are permitted, a Fund will deal with BlackRock on an arms-length basis.

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

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

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

BTC, an affiliate of BlackRock, pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Funds. BlackRock will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interests in managing a securities lending program,

including but not limited to: (i) BlackRock as securities lending agent may have an incentive to, among other things, increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BlackRock and its affiliates; and (ii) BlackRock as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro rata allocation.

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

BlackRock may decline to make a securities loan on behalf of a Fund, discontinue lending on behalf of a Fund or terminate a securities loan on behalf of a Fund for any reason, including but not limited to regulatory requirements and/or market rules, liquidity considerations, or credit considerations, which may impact Funds by reducing or eliminating the volume of lending opportunities for certain types of loans, loans in particular markets, loans of particular securities or types of securities, or for loans overall. In addition, some borrowers may prefer certain BlackRock lenders that provide additional protections against lender default that are favored by their prudential regulation.

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

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

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

BlackRock does not currently enter into arrangements to use the Fund’s assets for, or participate in, soft dollars, although BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

Subject to applicable law, BlackRock may select brokers that furnish BlackRock, the Funds, other BlackRock client accounts or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by

law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products.

Research or other services obtained in this manner may be used in servicing any or all of the Funds and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock, unless prohibited by applicable law, may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock, unless prohibited by applicable law, may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

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

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

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

It is also possible that, from time to time, BlackRock and /or its advisory clients (including other funds and separately managed accounts) may, subject to compliance with applicable law, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio.

BlackRock reserves the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of the Fund acquired for its own accounts or the account of a BlackRock advisory client. A large sale or redemption of shares of the Fund by BlackRock itself or a BlackRock advisory client could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund.

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

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

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

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

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

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

BlackRock and its directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and

investment strategies or constraints, positions may be taken by directors, officers and employees of BlackRock that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, the Fund, BRIL and BlackRock each have adopted a Code of Ethics in compliance with Section 17(j) of the Investment Company Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov.

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

BlackRock has adopted and implemented policies and procedures that are designed to address potential conflicts that arise in connection with the advisory services BlackRock provides to Funds and other clients. Certain BlackRock advisory personnel may take views, and make decisions or recommendations, that are different than or opposite those of other BlackRock advisory personnel. Certain portfolio management teams within BlackRock may make decisions or take (or refrain from taking) actions with respect to clients they advise in a manner different than or adverse to the decisions made or the actions taken (or not taken) by the Funds’ portfolio management teams. The various portfolio management teams may not share information with each other, including as a result of certain information barriers and other policies, and will not have any obligation or other duty to do so.

BlackRock has established certain information barriers and other policies to address the sharing of information between different businesses within BlackRock, including, effective on or about January 21, 2025, with respect to personnel responsible with managing portfolios and voting proxies with respect to certain index equity portfolios versus those responsible for managing portfolios and voting proxies with respect to all other portfolios. As a result of information barriers, certain units of BlackRock generally will not have access, or will have limited access, to certain information and personnel, including senior personnel, in other units of BlackRock, and generally will not manage the Funds with the benefit of information possessed by such other units. Therefore, BlackRock may not be able to review potential investments for the Funds with the benefit of information held by certain areas of BlackRock.

BlackRock may determine to move certain personnel, businesses, or business units from one side of an information barrier to the other side of the information barrier. In connection therewith, BlackRock personnel, businesses, and business units that were moved will no longer have access to the information and personnel from the side of the information barrier from which they were moved. Information obtained in connection with such changes to information barriers may limit or restrict the ability of BlackRock to engage in or otherwise effect transactions on behalf of the Funds (including purchasing or selling securities that BlackRock may otherwise have purchased or sold for a client in the absence of a change to an information barrier). Information barriers may not have their intended impact due to, for example, changes in applicable law or inadvertent crossings of the barriers, and actions by personnel on one side of a barrier may impact the potential actions of personnel on the other side of a barrier.

Although the information barriers are intended to allow for independent portfolio management decision making and proxy voting among certain BlackRock businesses, the investment activities of BlackRock for BlackRock clients, as well as BlackRock’s proprietary accounts, may nonetheless limit the investment strategies and rights of other clients (including the Funds). As BlackRock’s assets under management increases, BlackRock clients may face greater negative impacts due to ownership restrictions and limitations imposed by laws, regulations, rules, regulators, or issuers. For example, in certain circumstances where a BlackRock client invests in securities issued by companies that operate in certain industries (e.g., banking, insurance, and utilities) or in certain emerging or international markets, or are subject to regulatory or corporate ownership restrictions (e.g., with mechanisms such as poison pills in place to prevent takeovers), or where a BlackRock client invests in certain futures and derivatives, there may be limits on the aggregate amount invested by BlackRock for its clients and BlackRock’s proprietary accounts that may not be exceeded without the grant of a license or other regulatory or corporate approval, order, consent, relief, waiver or non-disapproval or, if exceeded, may cause BlackRock or its clients to be subject to enforcement actions, disgorgement of share ownership or profits, regulatory restrictions, complex compliance reporting, increased compliance costs or suffer disadvantages or business restrictions. In light of certain restrictions, BlackRock may also seek to make indirect investments (e.g., using derivatives) on behalf of its clients to receive exposure to certain securities in excess of the applicable ownership restrictions and limitations when legally permitted that will expose such clients to additional costs and additional risks, including any risks associated with investing in derivatives. There may be limited availability of derivatives that provide indirect exposure to an impacted security. In addition, BlackRock clients can be subject to more than one ownership limitation depending on each client’s holdings, and each ownership limitation can impact multiple securities held by the client. Certain clients or shareholders may have their own overlapping obligations to monitor their compliance with ownership limitations across their investments.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or a BlackRock client or as a result of corporate actions by the issuer, the ability of BlackRock on behalf of clients to purchase or dispose of investments, or exercise rights (including voting) or undertake business transactions, may be restricted by law, regulation, rule, or organizational documents or otherwise impaired. For example, to meet the requirements of an ownership limitation or restriction, a client may be unable to purchase or directly hold a security the client would otherwise purchase or hold. The limitation or restriction may be based on the holdings of other BlackRock clients instead of the specific client being restricted. For index funds, this means a fund may not be able to track its index as closely as it would if it was not subject to an ownership limitation or restriction because the fund cannot acquire the amount of the impacted security included in its index. BlackRock on behalf of its clients may limit purchases, sell existing investments, utilize indirect investments, utilize information barriers, or otherwise restrict, forgo, or limit the exercise of rights (including transferring, outsourcing, or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds. These types of restrictions could negatively impact a client’s performance or ability to meet its investment objective.

When BlackRock or a BlackRock client is subject to an ownership limitation, BlackRock may in its discretion seek permission from the applicable issuers or regulators to exceed the limitation. However, there is no guarantee that permission will be granted, or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. The issuer and/or regulator may also require that BlackRock on behalf of itself and its clients take or refrain from taking certain actions in connection with the approval, order, consent, relief or non-disapproval, which BlackRock may accept if it believes the benefits outweigh the costs and may limit BlackRock from taking actions that it otherwise would take. In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients, taking into consideration benchmark weight and investment strategy. BlackRock may adopt certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may limit additional purchases in such securities or, with respect to ETFs, remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund. If client holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to reduce these positions to meet the applicable limitations and BlackRock or such client may be subject to regulatory actions. In these cases, the investments will be sold in a manner that BlackRock deems fair and equitable over time.

Ownership limitations are highly complex. It is possible that, despite BlackRock’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit or violate the corporate or regulatory approval, order, consent, relief or non-disapproval that was obtained.

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

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

Under an ETF Services Agreement, the Fund has, when applicable, retained BlackRock Investments, LLC (the “Distributor” or “BRIL”), an Affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units of the Fund (“ETF Services”). BRIL will retain a portion of the standard transaction fee received from Authorized Participants on each creation or redemption order from the Authorized Participant for the ETF Services provided. BlackRock collaborated with, and received payment from, Citibank, N.A. (“Citibank”) on the design and development of the ETF Services platform. Citibank may have, or from time to time may develop, additional relationships with BlackRock or funds managed by BFA and its affiliates.

In order to defray transaction expenses and protect against possible shareholder dilution, the Fund may collect certain fees from Authorized Participants in connection with cash substitutions for creation and redemption transactions. While BlackRock uses good faith estimates of the expected costs to the Fund in determining the rates for fees collected by the Fund related to creation and redemption activity, BlackRock may have incentives to improve Fund performance through the collection of these fees. As these charges are based on estimates, where the charges exceed actual transaction-related costs and/or expenses incurred by the Fund, Fund performance could improve as a result. BlackRock has established processes to oversee the determination of these estimates in an effort to mitigate this conflict.

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

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

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

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

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

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

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

Investment Advisory, Administrative and Distribution Services

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

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

BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear, the management fees, interest expense, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities, commodities or other financial instruments and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses (as determined by a majority of the Independent Trustees). For the avoidance of doubt, extraordinary expenses do not include expenses related to the organization of any subsidiary for the Fund or the ongoing corporate expenses of maintaining such subsidiary.

For its investment advisory services to the Fund in the table below, BFA is entitled to an annual investment advisory fee equal to the rate indicated below of the average daily value of the Fund’s net assets. The fees are accrued daily and typically paid monthly by the Fund.

Fund	Annual Rate
iShares Bloomberg Roll Select Commodity Strategy ETF	0.28 %

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

For the fiscal years noted below, the following table sets forth the management fees owed before any waivers and/or reimbursements and any fees or expenses waived and/or reimbursed. BFA also serves as investment adviser to the Subsidiary. No fee will be paid to BFA for the advisory services that it provides to the Subsidiary.

Fund	Management Fees Paid for the Fiscal Year Ended Oct. 31, 2024	Waivers and Reimbursements of Fees and Expenses for the Fiscal Year Ended Oct. 31, 2024	Management Fees Paid for the Fiscal Year Ended Oct. 31, 2023	Waivers and Reimbursements of Fees and Expenses for the Fiscal Year Ended Oct. 31, 2023	Management Fees Paid for the Fiscal Year Ended Oct. 31, 2022	Waivers and Reimbursements of Fees and Expenses for the Fiscal Year Ended Oct. 31, 2022
iShares Bloomberg Roll Select Commodity Strategy ETF1	$716,909	$14,090	$905,336	$24,786	$865,498	$21,919

BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other funds advised by BFA, or its affiliates, through February 28, 2026. The contractual waiver may be terminated prior to February 28, 2026 only upon written agreement of the Trust and BFA.

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

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

Portfolio Managers. As of October 31, 2024, the individuals named as Portfolio Managers in the Fund's Prospectus were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as follows:

Matthew DeCicco (as of December 31, 2024)
Types of Accounts	Number	Total Assets
Registered Investment Companies	0	N/A
Other Pooled Investment Vehicles	0	N/A
Other Accounts	0	N/A

Richard Mejzak
Types of Accounts	Number	Total Assets
Registered Investment Companies	9	$123,821,000,000
Other Pooled Investment Vehicles	20	6,535,000,000
Other Accounts	68	26,272,000,000

Orlando Montalvo
Types of Accounts	Number	Total Assets
Registered Investment Companies	13	$9,004,000,000
Other Pooled Investment Vehicles	17	1,214,000,000
Other Accounts	8	2,000,000

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

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

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of October 31, 2024:

Portfolio Manager Compensation Overview

The discussion below describes the Portfolio Managers' compensation as of October 31, 2024.

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

Each portfolio manager receives base compensation based on their position with the firm, as well as retirement and other benefits offered to all BlackRock employees. Additionally, each portfolio manager receives discretionary incentive compensation, determined based on several components, including: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the performance of portfolios managed by the portfolio manager and the

team relative to the portfolios’ investment objectives (which in the case of index ETFs would be how closely the ETF tracks its underlying index), and the individual’s performance and contribution to the overall performance of these portfolios and BlackRock. Discretionary incentive compensation is paid in cash up to a certain threshold with the remaining portion represented by deferred BlackRock, Inc. stock awards. In some cases, additional deferred BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance.

As of October 31, 2024, the Portfolio Managers did not beneficially own shares of the Fund.

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

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

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

Administrator, Custodian and Transfer Agent.

State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Fund under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is One Congress Street, Suite 1, Boston, MA 02114-2016. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and the Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for the Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA. BFA pays the compensation because it has agreed to pay these operating expenses under the Investment Advisory Agreement as described therein.

JPMorgan serves as custodian for the Fund in connection with certain securities lending activities under a Custody Services Agreement. JPMorgan’s principal address is 383 Madison Avenue, 11th Floor, New York, NY 10179. Pursuant to the Custody Services Agreement with BTC and the Trust, JPMorgan provides custody and related services required to facilitate securities lending by the Fund. JPMorgan maintains custody as may be necessary to facilitate Fund securities lending activity in coordination with other funds, maintains custodial records and provides other services. As compensation for these services, JPMorgan receives certain fees and expenses paid by BTC from its compensation for its services as securities lending agent.

Distributor. The Distributor's principal address is 50 Hudson Yards, New York, NY 10001. Shares are continuously offered for sale by the Fund through the Distributor or its agent only in Creation Units, as described in the Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are generally not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its

agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

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

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

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

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

If the Fund were to engage in securities lending, it would retain a portion of the securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending, including custodial costs of JPMorgan. To the extent that the Fund engages in securities lending, the Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

To the extent that the Fund invests cash collateral in a non-government money market fund, the Fund may be subject to a discretionary liquidity fee of up to 2% on all redemptions. Discretionary liquidity fees may be imposed or terminated at any time at the discretion of the board of directors of the money market fund, or its delegate, if it is determined that such fee would be, or would not be, respectively, in the best interest of the money market fund. Additionally, the Fund will be subject to a mandatory liquidity fee if the money market fund’s total net redemptions on a single day exceed 5% of the money market fund’s net assets, unless the liquidity costs are de minimis (i.e., less than one basis point (0.01%)). The money market fund will determine the size of the mandatory liquidity fee by making a good faith estimate of certain costs the money market fund would incur if it were to sell a pro rata amount of each security in the portfolio to satisfy the amount of net redemptions on that day. There is no limit to the size of a mandatory liquidity fee. If the money market fund cannot estimate the costs of selling a pro rata amount of each portfolio security in good faith and supported by data, it is required to apply a default liquidity fee of 1% on the value of shares redeemed on that day. The imposition of any such discretionary or mandatory liquidity fee would reduce the Fund’s returns on securities lending.

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

Pursuant to the current Securities Lending Agency Agreement:

(i) domestic equity funds retain 81% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees;

(ii) international equity funds retain 82% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees;

(iii) fixed-income funds retain 82% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees; and

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

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the iShares Complex (as defined in the “Management—Trustees and Officers section of this SAI) in a calendar year exceeds a specified threshold, pursuant to the current Securities Lending Agency Agreement:

(i) each applicable domestic equity fund will receive 84% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of the securities lending income plus collateral investment fees;

(ii) each applicable international equity fund will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees;

(iii) each applicable fixed-income fund will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees; and

(iv) each applicable fund-of-funds will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

No services have been provided by BTC as the Fund’s securities lending agent, and the Fund had no income and fees/compensation related to securities lending activities for the fiscal year ended October 31, 2024.

Payments by BFA and its Affiliates. BFA and/or its affiliates (“BFA Entities”) pay certain broker-dealers, registered investment advisers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Fund and other funds or products sponsored and/or advised by BFA Entities (collectively for purposes of this section, the “Products”). BFA Entities make these payments from their own assets and not from the assets of the Fund. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Fund or other Products (including, if applicable, any underlying Products held by the Fund), these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other Products. BFA Entities make payments for Intermediaries’ participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Fund and other Products, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Fund or other Products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Fund or other Products available to their clients, in some cases at a waived or reduced commission rate or ticket charge, develop new products that feature iShares, create educational content about the Fund or other Products that is featured on an Intermediary’s platform, or otherwise promote the Fund or other Products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the business of the BFA Entities or facilitate investment in the Fund or other Products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients, what services to provide for various products or what marketing content to make available to its clients based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients. These financial incentives may cause the Intermediary to recommend the Fund or other Products or otherwise

promote the Fund or other Products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

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

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

In addition, BFA Entities have entered into other contractual arrangements with Intermediaries and certain other third parties that the BFA Entities believe may benefit the business of the BFA Entities or facilitate investment in the Fund or certain Products. Such agreements can include payments by BFA Entities to such Intermediaries and third parties for data collection and provision, technology support, platform enhancement, or educational content, co-marketing and cross-promotional efforts. In certain cases, such payments to Intermediaries are subject to certain minimum payment levels or tiered payments. With respect to certain funds and Products, payments by the BFA Entities may take the form of, among other things, “due diligence” payments for an Intermediary’s review of such funds and Products; payment for providing employee training and information relating to such funds and Products; fees for access (in some cases on a preferential basis) to an Intermediary’s registered representatives, salespersons or other personnel, fees for maintaining an Intermediary’s investor platform, “shelf space” payments for making such funds and Products available on the Intermediary’s platform or fees for providing assistance in promoting the sale of such funds and Products. In such cases, the payments to Intermediaries may be tiered or based on a percentage of the value of the funds and Products held by customers of the applicable Intermediary and may also be subject to minimum payment levels. Payments made pursuant to such arrangements may vary in any year and may be different for different Intermediaries and third parties and may reflect different services provided. As of the date of this SAI, the Intermediaries and other third parties (or their respective affiliates) receiving one or more types of the contractual payments described above include (in addition to FBS and NFS): &Partners, Advisor Credit Exchange, AE Wealth Management, LLC, American Enterprise Investment Services, Inc., Avantax Investment Services, Inc., BNY Mellon Capital Markets, LLC, BNY Mellon Performance & Risk Analytics, LLC, Cetera Financial Group, Inc., Charles Schwab & Co., Inc., Clearstream Fund Centre AG, Commonwealth Equity Services, LLC, Dorsey Wright and Associates, LLC, Dynasty Financial Partners LLC, E*Trade Securities LLC, Envestnet Asset Management, Inc., LPL Financial LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, MML Investors Services, LLC, Morgan Stanley Smith Barney LLC, Northwestern Mutual Investment Services, LLC, Orion Portfolio Solutions, LLC, Pershing LLC, Raymond James Financial Services, Inc., Riskalyze, Inc., Sanctuary Wealth Group, LLC, TD Ameritrade, Inc., UBS Financial Services Inc., Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC. Any additions, modifications, or deletions to Intermediaries and other third parties listed above that have occurred since the date of this SAI are not included in the list.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed in the immediately preceding paragraph. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more Products, including the Fund, in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any

payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Fund or other Products.

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

Determination of Net Asset Value

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

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

Fixed-Income Investments. Fixed-income securities for which market quotations are readily available are generally valued using such securities’ current market value. The Fund values fixed-income portfolio securities using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. 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), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and/or other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the 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 amortized cost method of valuation may be used with respect to debt obligations with 60 days or less remaining to maturity unless such method does not represent fair value. Certain fixed-income investments, 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 issuer, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche.

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

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

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

The price the Fund could receive upon the sale of any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for assets that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by the Fund, and the Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The Fund’s ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

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

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

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

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

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

When determining the price for a Fair Value Asset, BFA will seek to determine the price that the Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction on the date on which the asset or liability is being valued, and does not seek to determine the price the Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. Fair value determinations will be based upon all

available factors that BFA deems relevant at the time of the determination, and may be based on analytical values determined by BFA using proprietary or third-party valuation models.

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

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

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

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

Brokerage Transactions

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

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

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

services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

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

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

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

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

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

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

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

Initial public offerings (“IPOs”) of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to

allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in the Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

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

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

The table below sets forth the brokerage commissions paid by the Fund for the fiscal years noted. Any differences in brokerage commissions paid by the Fund from year to year are principally due to increases or decreases in the Fund’s assets over those periods or changes to the allocation of equities and derivatives in the Fund’s portfolio:

Fund Inception Date	Brokerage Commissions Paid During Fiscal Year Ended October 31, 2024	Brokerage Commissions Paid During Fiscal Year Ended October 31, 2023	Brokerage Commissions Paid During Fiscal Year Ended October 31, 2022
04/03/18	$205,868	$285,241	$247,729

The Fund did not pay any brokerage commissions to BRIL, an affiliate of BFA, or to any other broker-dealer that is part of the BlackRock group of companies, during the fiscal year ended October 31, 2024.

allocated among the Fund and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BlackRock may deal, trade and invest for its own account in the types of securities in which the Fund may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

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

Additional Information Concerning the Trust

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

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

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

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

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

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

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

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

take other similar actions with, to or into another fund. The Trust or a fund may be terminated by a majority vote of the Board, or the affirmative vote of a majority of the shareholders of the Trust or such fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or a fund, the Trust or a fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

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

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

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

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

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

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any

time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

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

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

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

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

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on the Fund's NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the Listing Exchange closes earlier than normal, the Fund may require orders to be placed earlier in the day. The following table sets forth the number of shares of the Fund that constitute a Creation Unit for the Fund and the approximate value of such Creation Unit as of November 30, 2024:

Shares Per Creation Unit	Approximate Value Per Creation Unit (U.S.$)
50,000	$2,457,398.80

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

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

Fund Deposit. The consideration for purchase of Creation Units of the Fund generally consists of the in-kind deposit of Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which will be applicable (subject to possible amendment or correction) to

creation requests received in proper form. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

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

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

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

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

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

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

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

should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

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

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

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

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

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

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

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

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the sub-custodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant sub-custodian or sub-custodians, the Distributor or its agent and BFA shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit.

Creation Units of the Fund are generally issued on a “T+1 basis” (i.e., one Business Day after trade date). However, the Fund reserves the right to settle Creation Unit transactions on a different basis, if necessary or appropriate under the circumstances and compliant with applicable law. These circumstances may include, among others, accommodating non-U.S. market holiday schedules and accounting for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security).

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

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

Costs Associated with Creation Transactions.

A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same, regardless of the number of Creation Units purchased by the Authorized Participant on the applicable Business Day.

In order to defray transaction expenses for the Fund and protect against possible shareholder dilution, if a creation transaction consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs based on historical data or other inputs, at BlackRock’s discretion, and may include part or all of the spread between the expected bid and offer side of the market and anticipated market impact). However, the Fund is not obligated to trade identical securities to the securities identified by BlackRock in estimating these transaction and other costs and

expenses. In certain cases, BlackRock or an affiliate may determine in its discretion to deviate from the regular charge, subject to the maximum amounts shown below.

Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth the Fund's standard creation transaction fees and maximum additional charge (as described above):

Standard Creation Transaction Fee	Maximum Additional Charge*
$225	7.0 %

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

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

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

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

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

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security in certain circumstances, including: (i) when the delivery of a Fund Security to the Authorized Participant (or to an investor on whose behalf the Authorized Participant is acting) would be restricted under applicable securities or other local laws or due to a trading restriction; (ii) when the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws; (iii) when the delivery of a Fund Security to the Authorized Participant would result in unfavorable tax treatment; (iv) when a Fund Security cannot be settled or otherwise delivered in time to facilitate an in-kind redemption; or (v) in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund generally redeems Creation Units for Fund Securities, but the Fund reserves the right to utilize a cash option for redemption of Creation Units. The Redemption Basket may also be modified to minimize the Cash Component by redistributing the cash to the Fund Securities portion of the Redemption Basket through systematically rounding. The rounding methodology allows position

sizes of securities in the Fund Securities to be “rounded up,” while limiting the maximum allowed percentage change in weight and share quantity of any given security in the Redemption Basket. Redemption Baskets may also be modified to position a fund towards a forward index rebalance to reflect revisions that account for index additions, deletions, and re-weights.

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

Costs Associated with Redemption Transactions.

A redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the Fund. The standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day.

In order to defray transaction expenses for the Fund and protect against possible shareholder dilution, if a redemption transaction consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs based on historical data or other inputs, at BlackRock’s discretion, and may include part or all of the spread between the expected bid and offer side of the market and anticipated market impact). However, the Fund is not obligated to trade identical securities to the securities identified by BlackRock in estimating these transaction and other costs and expenses. In certain cases, BlackRock or an affiliate may determine in its discretion to deviate from the regular charge, subject to the maximum amounts shown below.

Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth the Fund's standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption Transaction Fee	Maximum Additional Charge*
$225	2.0 %

As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

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

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Distributor or its agent in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor's broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit

proper submission of the request by an Authorized Participant and transfer of the shares to the Fund's transfer agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

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

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

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

Deliveries of redemption proceeds by the Fund are generally made within one Business Day (i.e., “T+1”). However, the Fund reserves the right to settle deliveries of redemption proceeds on a different basis, if necessary or appropriate under the circumstances and compliant with applicable law. These circumstances may include, among others, accommodating non-U.S. market holiday schedules and accounting for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security).

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

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

Custom Baskets. Creation and Redemption baskets may differ and the Fund will accept “custom baskets.” A custom basket may include any of the following: (i) a basket that is composed of a non-representative selection of the Fund's portfolio holdings; (ii) a representative basket that is different from the initial basket used in transactions on the same business day; or (iii) a basket that contains bespoke cash substitutions for a single Authorized Participant. The Fund has adopted policies and procedures that govern the construction and acceptance of baskets, including heightened requirements for certain types of custom baskets. Such policies and procedures provide the parameters for the construction and acceptance of custom baskets that are in the best interests of the Fund and its shareholders, establish processes for revisions to, or deviations from, such parameters, and specify the titles and roles of the employees of BFA who are required to review each custom basket for

compliance with those parameters. In addition, when constructing custom baskets for redemptions, the tax efficiency of the Fund may be taken into account. The policies and procedures distinguish among different types of custom baskets that may be used for the Fund and impose different requirements for different types of custom baskets in order to seek to mitigate against potential risks of conflicts and/or overreaching by an Authorized Participant. BlackRock has established a governance process to oversee basket compliance for the Fund, as set forth in the Fund's policies and procedures.

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

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

Taxes

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

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

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

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

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

such income or gains are not distributed. If the Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If the Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

The Subsidiary will not be subject to U.S. federal income tax. The Subsidiary will, however, be considered a controlled foreign corporation, and the Fund will be required to include as income annually amounts earned by the Subsidiary during that year. The Fund will be subject to the distribution requirements described above on such Subsidiary income, whether or not the Subsidiary makes a distribution to the Fund during the taxable year. Based on final regulations issued by the IRS on which taxpayers may rely for taxable years beginning after September 28, 2016, the Fund expects its income with respect to the Subsidiary to be qualifying income. In the future, if the IRS issues regulations or other guidance, or Congress enacts legislation, limiting the circumstances in which the Fund’s income with respect to the Subsidiary will be considered “qualifying income,” the Fund might be required to make changes to its operations, which could reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders could also experience adverse tax consequences in such circumstances.

In addition, the Fund’s income from the Subsidiary will be treated as ordinary income. If the Fund were able to invest directly in commodity-linked derivatives, its gains and losses would generally be treated as 60% long-term and 40% short-term gain or loss, to the extent such derivatives are subject to the rules for Section 1256 futures contracts. See “Taxation of Certain Derivatives” below.

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

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

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

As of October 31, 2024, the tax year-end of the Fund, the Fund had non-expiring capital loss carryforwards in the amount of $8,542 available to offset future realized capital gains.

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

The Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if the Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over

the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that the Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of the Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts.

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

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

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

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

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

Sales of Shares. Upon the sale or exchange of shares of the Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by the Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option or contract to acquire substantially identical shares, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares

acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of the Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

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

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

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

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

As a result of entering into swap contracts, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing

transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, the Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from a U.S. real estate investment trust (“REIT”)) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

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

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

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

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

Reporting. If a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

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

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

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

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

Similar consequences would generally apply to a foreign shareholder's gain on the sale of Fund shares unless the Fund is domestically controlled (meaning that more than 50% of the value of the Fund's shares is held by U.S. shareholders) or the foreign shareholder owns no more than 5% of the Fund's shares at any time during the five-year period ending on the date of sale. Finally, a domestically controlled Fund may be required to recognize a portion of its gain on the in-kind distribution of

certain U.S. real property interests. Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in the Fund.

A foreign shareholder also may be subject to certain “wash sale” rules to prevent the avoidance of the tax filing and payment obligations discussed above through the sale and repurchase of Fund shares.

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

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items paid to: (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to: (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information concerning their account holders, or (ii) in the event an intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

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

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

Open-End Active and Fixed Income Index Fund Proxy Voting Policy

Procedures Governing Delegation of Proxy Voting to Fund Advisers

Effective Date: January 1, 2025

________________________________________

Applies to the following types of Funds registered under the 1940 Act:

☐ Index Equity Mutual Funds and Exchange-Traded Funds

☒ Open-End Active and Fixed Income Index Mutual Funds and Exchange-Traded Funds

☐ Money Market Funds

☐ Closed-End Funds

☐ Other

________________________________________

Objective and Scope

Set forth below is the Open-End Active and Fixed Income Index Fund Proxy Voting Policy.

Policy / Document Requirements and Statements

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

BlackRock has adopted the BlackRock Active Investment Stewardship Global Engagement and Voting Guidelines (as from time to time amended, the “Guidelines”) governing proxy voting by active and fixed income index Funds managed by BlackRock. The Guidelines include “climate and decarbonization” guidelines which apply to the Funds listed in Appendix A, if any.

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

Conflicts Management

BlackRock Active Investment Stewardship (“BAIS”) maintains policies and procedures that seek to prevent undue influence on BlackRock’s proxy voting activity and to mitigate material conflicts of interest in the exercise of proxy voting responsibilities. Potential material conflicts, and the resultant potential for undue influence, might be due to a relationship between the investee company (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock’s affiliates or employees, or a Fund or a Fund’s affiliates. BlackRock has taken certain steps to mitigate potential conflicts, which are outlined in detail in the Guidelines. In mitigating conflicts, BAIS will adhere to the Guidelines.

In certain instances, BAIS will engage an independent third-party voting service provider to make proxy voting recommendations as a further safeguard to avoid potential conflicts of interest, to satisfy regulatory compliance requirements, or as may be otherwise required by applicable law.

A-2

With respect to the relationship between securities lending and proxy voting, shares on loan cannot be voted and BlackRock may determine to recall them for voting, as guided by BlackRock’s fiduciary responsibility to act in clients’ financial interests. The Guidelines set forth BlackRock’s approach to recalling securities on loan in connection with proxy voting.

Reports to the Board

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

Overview

This document provides high level guidance on how BlackRock Active Investment Stewardship (BAIS) views corporate governance matters that are commonly put to a shareholder vote, or on which investors engage with issuers. BAIS works in partnership with BlackRock’s investment teams, excluding index equity, providing expertise on investment stewardship, engaging with companies on behalf of those teams when appropriate, and assisting in recommending, operationalizing and reporting on voting decisions. The guidance informs BAIS’ voting recommendations to BlackRock’s active portfolio managers. It applies to active equity holdings in BlackRock’s fundamental equity, systematic equity and multi-asset solutions strategies. It also may apply to holdings in BlackRock’s index and active fixed income strategies, to the extent those strategies hold voting securities or conduct issuer engagements. The guidelines are not prescriptive as active portfolio managers have discretion as to how they integrate these guidelines within their investment processes in light of their clients’ or funds’ investment objectives. There are separate, independently developed principles and voting policies that are applied to BlackRock’s index equity investments by a distinct and independent function, BlackRock Investment Stewardship.

Introduction to BlackRock

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

About BlackRock Active Investment Stewardship

BlackRock Active Investment Stewardship (BAIS) is a specialist team within the Portfolio Management Group and manages BlackRock’s stewardship engagement and voting on behalf of clients invested in active strategies globally. BAIS is also responsible for engagement with issuers in index fixed income strategies, where appropriate. Our activities are informed by these Global Engagement and Voting Guidelines (“the Guidelines”) and insights from active investment analysts and portfolio managers, with whom we work closely in engaging companies and voting at shareholder meetings.

Engagement with public companies is the foundation of our approach to stewardship within fundamental active investing. Through direct dialogue with company leadership, we seek to understand their businesses and how they manage risks and opportunities to deliver durable, risk adjusted financial returns. Generally, portfolio managers and stewardship specialists engage jointly on substantive matters. Our discussions focus on topics relevant to a company’s success over time including governance and leadership, corporate strategy, capital structure and financial performance, operations and sustainability-related risks, as well as macro-economic, geopolitical and sector dynamics. We aim to be constructive investors and are generally supportive of management teams that have a track record of financial value creation. We aim to build and maintain strong relationships with company leadership based on open dialogue and mutual respect.

Different active equity strategies may implement these voting guidelines differently, as a result of the latitude the portfolio manager has to make independent voting decisions aligned with their portfolio objectives and investment strategy. For example, BAIS will generally vote the holdings in Systematic Active Equity portfolios in accordance with these guidelines. We provide voting recommendations to fundamental equity portfolio managers, who may determine to vote differently based on their portfolio investment objectives and strategy.

These guidelines discuss corporate governance topics on which we may engage with management teams and board directors(1) and matters that routinely come to a shareholder vote. We recognize that accepted corporate governance norms can differ across markets, and believe these guidelines represent globally applicable elements of governance that support a company’s ability to manage material risks and opportunities and deliver financial returns to investors. Generally, we believe companies should observe accepted corporate governance norms within their local markets or, particularly in markets without well-established norms, aspire to widely recognized international best practices. As one of many minority shareholders, BlackRock cannot – and does not try to – direct a company’s strategy or its implementation. We look to companies to provide disclosures that explain how their approach to corporate governance best aligns with the financial interests of their investors.

Our approach to stewardship within active equities

As shareholders of public companies, BlackRock’s clients have certain fundamental rights, including the right to vote on proposals put forth by a company’s management or its shareholders. The voting rights attached to these clients’ holdings are an important mechanism for investors to express support for, or concern about, a company’s performance. As a fiduciary, BlackRock is legally required to make proxy voting determinations, on behalf of clients who have delegated voting authority to us, in a manner that is consistent with their investment objectives.

In general, we tend to support the recommendations of the board of directors and management. As indicated below, we may vote against management recommendations when we have concerns about how companies are serving the financial interests of our clients as their shareholders. We take a globally consistent approach to voting but consider the different corporate governance regulations and norms in various markets. Votes are determined on a case-by-case basis, in the context of a company’s situation and the investment mandate we have from clients. Please see page 16 for more information about how we fulfil and oversee BlackRock’s non-index equity investment stewardship responsibilities.

Our approach to stewardship within fixed income

Although fixed income investors do not have the right to vote at shareholder meetings, issuer engagement is a component of fixed income investment strategies at BlackRock, particularly those with sustainability objectives in addition to financial objectives. Most corporate governance-related fixed income engagements are undertaken in conjunction with the active investment stewardship team, and often active equity investors. In addition to the topics listed below, engagement with fixed

(1)

References to the board, board directors or non-executive directors should be understood to include supervisory boards and their members, where relevant.

A-5

income investment teams can help inform an issuer’s approach to structuring specialist issuances, such as green bonds, and the standard terms and information in bond documentation.

Boards of Directors

Roles and responsibilities

There is widespread consensus that the foundation of good corporate governance is an effective board of directors that is able to advise and supervise management in an independent and objective manner(2).

We look to the board of directors (hereafter ‘the board’) to have an oversight role in the establishment and realization of a company’s strategy, purpose and culture. These constructs are interdependent and, when aligned, can better position a company to be resilient in the face of a changing business environment, help reduce the risks of corporate or employee misconduct, and attract and retain the caliber of workers necessary to deliver financial performance over time.

In promoting the success of the company, the board ensures the necessary resources, policies and procedures are in place to help management meet its strategic objectives within an agreed risk tolerance.

One of the most important responsibilities of the board is to appoint, and remove as necessary, the chief executive officer (CEO). In addition, the board plays a meaningful role in monitoring the performance of the CEO and other key executives, determining executive compensation, ensuring a rigorous audit, overseeing strategy execution and risk management and engaging with shareholders, and other stakeholders, as necessary.

Composition and effectiveness

Appointment process

A formal and transparent process for identifying and appointing director candidates is critical to ensuring the board is composed of directors with the appropriate mix of skills and experience. The board or a sub-committee should determine the general criteria given the company’s circumstances (e.g., sector, maturity, geographic footprint) and any additional criteria for a specific role being filled (e.g., financial expertise, industry track record). To inform the process, we encourage companies to review the skills and experience of incumbent directors to identify any gaps and whether a director candidate’s characteristics would be additive. We welcome disclosures that explain how the board considered different skills, backgrounds and experience to ensure the directors collectively can be effective in fulfilling their responsibilities. We assess a company’s board composition against that of its peer group and local market requirements.

Shareholders periodically vote to elect, remove and nominate directors to serve on the board. We may vote against the election of the most senior independent director, or the chair of the relevant committee, where a company has not demonstrated it has an appointment process that results in a high functioning board with the appropriate complement of skills, backgrounds and experience amongst the directors to support strong financial performance over time. We may vote against newly nominated directors who do not seem to have the appropriate skills or experience to contribute to the board’s effectiveness.

Independence

Director independence from management, significant shareholders or other stakeholders (e.g., government or employees) is of paramount importance to the protection of the interests of minority shareholders such as BlackRock’s clients. At least half of the directors should be independent and free from conflicts of interest or undue influence(3). This ensures sufficient independent directors to have appropriately independent board committees. Companies domiciled in markets with a higher threshold for board independence should meet those requirements.

(2)

See the Corporate Governance Codes of Germany, Japan, and the UK, as well as the corporate governance principles of the US Business Roundtable as examples.

(3)

Common impediments to independence may include but are not limited to: current or recent employment at the company or a subsidiary; being, or representing, a shareholder with a substantial shareholding in the company; interlocking directorships; lengthy tenure, and having any other interest, business, or other relationship which could, or could reasonably be perceived to, materially interfere with a director’s ability to act in the best interests of the company and shareholders.

A-6

We may vote against the election of non-independent directors if the board does not have a sufficient balance of independence. We may also vote against the election of the chair of the committee responsible for board composition if this is a perennial issue.

Independent board leadership

Practices across markets differ, as do board structures, but we observe two main approaches to independent board leadership. One is a non-executive, independent chair of the board who is responsible for leading the board in the effective exercise of its duties. The other is a lead or senior independent director, who is responsible for coordinating with the other non-executive directors and working closely with the executive chair on the board agenda and other board procedures. In this case, the executive chair and the lead independent director work together to ensure the board is effectively fulfilling its responsibilities. In our view, the independent leader of the board, and/or the chair of a relevant committee, should be available to investors to discuss board governance matters such as CEO succession, executive pay, and board performance. We look to boards to explain their independent board leadership model and how it serves the interests of shareholders.

We may vote against the election of the chair of the committee responsible for board composition if there is not an identified independent leader of the board with clear responsibilities for board performance. We may vote against the most senior independent director if the board has a policy of not engaging with shareholders.

Tenure and succession

Boards should establish the length of time a director would normally be expected to serve, in line with market norms where those exist. In such markets, we find it helpful when companies disclose their approach to director tenure particularly around the contributions of directors who have served for longer periods than provided for in local practices. In our experience, long-serving directors could become less independent given their relationship with management and involvement in past board decisions.

Succession planning for board roles helps achieve the appropriate cadence of turnover that balances renewal through the regular introduction of directors with fresh perspectives and expertise with continuity through the retention of directors with long-term knowledge of the board and company.

In markets where there is not specific director tenure guidance, we may vote against the election of the chair of the committee responsible for board composition if there is not a clearly disclosed approach to director tenure and board renewal. We may vote against the election of directors who have served for longer duration than typical in markets with specific guidance, where the case for their continued service is not evident.

Capacity

To be effective and engaged, directors must commit appropriate time and energy to the role. A board should assess the ability of its members to maintain an appropriate focus on board matters and the company taking into consideration competing responsibilities. We recognize that board leadership roles vary across markets in responsibilities and required time commitment but note that they are generally more intensive than a standard directorship. We will take local norms and practices into consideration when making our voting determinations across markets.

We may vote against the election of directors who do not seem to have sufficient capacity to effectively fulfil their duties to the board and company.

Director elections

In support of director accountability to shareholders, directors should stand for election on a regular basis, ideally annually. A classified board structure may be justified by a company when it needs consistency and stability during a time of transition, or on the basis of its business model, e.g., a non-operating company such as closed-end funds.

Shareholders should have the opportunity to evaluate nominated directors individually rather than in bundled slates. We look to companies to provide sufficient information on each director standing for election so that shareholders can assess their capabilities and suitability. We will not support the election of directors whose names and biographical details have not been disclosed sufficiently in advance of the shareholder meeting.

A-7

Each director’s appointment should be dependent on receiving a simple majority of the votes cast at the shareholder meeting. Where a company’s practices differ, we look to the board to provide a detailed explanation as to how its approach best serves investors’ interests.

We may vote for shareholder or management proposals seeking to establish annual election of directors and/or a simple majority vote standard for director elections. We may vote against all the directors standing for election as part of a single slate if we have concerns about the profile or performance of an individual director.

Committees

Many boards establish committees to focus on specific responsibilities of the board such as audit and risk, governance and human capital, and executive compensation, amongst other matters. We do not prescribe to companies what committees they should establish but we seek to understand the board’s rationale for the committee structure it determines is appropriate. We note that, in some markets, regulation requires such committees. The responsibilities of each committee should be clear, and the board should ensure that all critical matters are assigned either to the full board or to one of the committees. The board should disclose to shareholders the structure, membership, proportion of independent directors, and responsibilities of each committee. The responsibilities we typically see assigned to the three most common committees include:

•

Audit and risk – oversight responsibilities for the integrity of financial reporting, risk management and compliance with legal and regulatory requirements; may also play an oversight role in relation to the internal audit function and whistleblowing mechanisms.

•

Nominating, governance and human capital – ensures appropriate corporate governance principles and practices including the periodic review of board performance; responsible for succession planning for CEO and key board roles, as well as the director appointment process; may also have oversight responsibilities for human capital management strategies including corporate culture and purpose.

•

Executive compensation – determines the compensation policies and programs for the CEO and other executive officers, approves annual awards and payments under the policies; may also have oversight responsibilities for firm-wide compensation policies.

We may vote against the election of the chair of the committee or other directors serving as committee members to convey our concerns and provide feedback on how a committee has undertaken its responsibilities. We may vote against the election of the most senior non-executive director if there is not a clearly disclosed approach to board committees.

Board and director evaluation

We consider it best practice for companies to conduct an annual review of the performance of the board, the committees, the chair and individual directors. Periodically, this review could be undertaken by an independent third party able to bring objective perspectives to the board on governance and performance. We encourage companies to disclose their approach to and objectives of evaluations, including any changes made to the board’s approach as a result.

Access to independent advice

To support the directors in effectively fulfilling their duties to the company and shareholders, they should have access to independent advice. When circumstances warrant, boards should be able to retain independent third parties to advise on critical matters. These might include new industry developments such as emergent and disruptive technology, operating events with material consequences for the company’s reputation and/or performance, or significant transactions. Board committees may similarly retain third parties to advise them on specialist matters such as audit, compensation and succession planning.

Executive compensation

Boards should establish compensation arrangements that enable the company to recruit, retain and reward the caliber of executive management necessary to lead and operate the company to deliver superior financial returns over time. We focus on alignment between variable pay and a company’s financial performance.

Generally, executive compensation arrangements have four components: base salary, annual bonus that rewards performance against short-term metrics, share-based incentives that reward performance against long-term metrics, and

A-8

pensions and benefits. In our observation, base salary, pensions and benefits are largely set relative to market norms and benchmarks. The annual bonus and share-based incentive, or variable pay plans, tend to be tailored to the company, its sector and long-term strategy, as well as the individuals the board is seeking to recruit and motivate.

Recognizing the unique circumstances of each company, we determine whether to support a company’s approach to executive compensation on a case-by-case basis. We rely on companies providing sufficient quantitative and qualitative information in their disclosures to enable shareholders to understand the compensation arrangements and assess the alignment with investors’ interests. Features we look for in compensation arrangements include:

•

Fixed pay components, including base salary, benefits and prerequisites that are appropriate in the context of the company’s size, sector and market.

•

Variable pay subject to performance metrics that are closely linked to the company’s short- and long-term strategic objectives.

•

Long-term incentives that motivate sustained performance across a multi-year period.

•

A balance between fixed and variable pay, short- and long-term incentives, and specific instruments (cash and equity awards) that promotes pay program durability and seldom necessitates one-off, discretionary payments.

•

Outcomes that are consistent with the returns to investors over the relevant time period.

•

Board discretion, if allowed within the variable pay arrangements, to be used sparingly, responsibly and transparently.

•

A requirement, that participants in long-term share-based incentive plans build a meaningful shareholding in the company within a defined time period, as determined by the board.

•

Change of control provisions that appropriately balance the interests of executives and shareholders.

•

Clawback or malus provisions that allow the company to recoup or hold back variable compensation from individuals whose awards were based on fraudulent activities, misstated financial reports, or executive misconduct.

•

Severance arrangements that protect the company’s interests but do not cost more than is contractual.

We may vote against proposals to introduce new share-based incentives, approve existing policies or plans, or approve the compensation report where we do not see alignment between executive compensation arrangements and our clients’ financial interests. When there is not an alternative, or where there have been multi-year issues with compensation misaligned with performance, we may vote against the election of the chair of the responsible committee, or the most senior independent director.

Non-executive director compensation

Companies generally pay non-executive directors an annual retainer or fee in cash, shares or a combination of the two. Some companies also pay additional fees for service on board committees or in board leadership roles. We do not support non-executive directors participating in performance-based incentive plans as doing so may create a conflict of interest and undermine their independence from management, whom they oversee.

Capital structure

Boards are responsible for ensuring senior executive leadership has established a capital strategy that achieves appropriate capital allocation and management in support of long-term financial resilience.

Where company practices diverge from those set out below, we look for companies to disclose why they view these practices to be aligned with shareholders’ interests. We may vote against management proposals seeking capital-related authorities or the election of the most senior independent director if we have concerns about a company’s approach. We may also support a shareholder proposal seeking conversion of shares with differentiated voting rights to a one-share, one-vote standard.

Share issuance

We assess requests for share issuance for particular transactions on a case-by-case basis. We will generally support authorities to issue shares when subject to pre-emptive rights, and up to 20% absent pre-emptive rights. Companies should seek regular approval of these authorities to allow shareholders to take into consideration how prior authorities were used, as well as the current circumstances of the company and the market environment.

A-9

Share buybacks

We assess share buyback proposals in the context of the company’s disclosed capital management strategy and management’s determination of the appropriate balance between investment that supports the long-term growth of the company and returning cash to investors. We also take into consideration the effect of a buyback program on the company’s balance sheet and executive compensation arrangements and the price at which shares are repurchased relative to market price. Companies should seek regular approval of these authorities to allow shareholders to take into consideration how prior authorities were used, as well as the current circumstances of the company and the market environment.

We would normally expect companies to cancel repurchased shares. If a company plans to retain them as treasury shares, management should provide a detailed rationale in the context of the disclosed capital management strategy.

Dividends

We generally defer to management and the board on dividend policy but may engage to seek further clarification where a proposed dividend appears out of line with the company’s financial position.

Differentiated voting rights

We prefer companies to adopt a one-share, one-vote structure for share classes with the same economic exposure. Certain companies, particularly those new to public markets, could make the case to adopt a differentiated voting rights structure, or dual class stock. In those situations, we encourage companies to evaluate and seek approval for their capital structure on a periodic basis.

Transactions and special situations

We monitor developments in transactions and special situations closely and undertake our own detailed analyses of proposals.

Mergers and acquisitions

We evaluate proposed mergers or acquisitions by assessing the financial outcome for our clients as minority shareholders. Management should provide an assessment of the proposed transaction’s strategic and financial rationale, along with its execution and operational risks. We review each transaction independently based on these factors and the degree to which the transaction enhances shareholder value. The board should consider establishing an ad hoc transaction committee to undertake an independent assessment of a significant merger or acquisition, in advance of making its recommendation to shareholders.

We will vote against transactions that, in our assessment, do not advance our clients’ financial interests.

Anti-takeover defenses

In principle, we do not support companies using anti-takeover defenses, also known as poison pills or shareholder rights plans, as they can entrench management and boards which have not delivered long-term shareholder value. By exception, a poison pill may be supported if its purpose is to delay a takeover that is considered sub-optimal and enable management to seek an improved offer. Similarly, management could make the case to use a poison pill to block a shareholder activism campaign that may be counter to the interests of other investors. Defense mechanisms introduced in these circumstances should be limited in term and threshold, and also be closely monitored by the independent members of the board. We look for a shareholder vote for any mechanisms expected to be in place for more than 12 months.

Shareholder activism

When companies are the focus of an activism campaign, we may engage with the activist to understand their analysis and objectives, once they have gone public. We will also engage with company management and possibly board members, especially those the activist may be seeking to replace. In our assessment, we evaluate various factors, including the concerns raised by the activist and the case for change; the quality of both the activist’s and management’s plans; and the qualifications of each party’s candidates. We evaluate each contested situation by assessing the potential financial outcome for our clients as minority shareholders.

A-10

We may support board candidates nominated by a shareholder activist if the activist has demonstrated that their case for change enhances shareholder value, or if the incumbent board members do not demonstrate the relevant skills and expertise or have a poor track record of protecting shareholders’ interests.

Significant shareholders and related party transactions

Boards of companies with affiliated shareholders or directors should be able to demonstrate that the interests of all shareholders are given equitable consideration.

Transactions with related parties, such as significant shareholders or companies connected with the public company, should be disclosed in detail and conducted on terms similar to what would objectively have been agreed with a non-related party. Such transactions should be reviewed and approved by the independent members of the board, and if voted on, only disinterested shareholders should vote.

Corporate reporting, risk management and audit

Investors depend on corporate reporting, both regulatory and voluntary, to understand a company’s strategy, its implementation and financial performance, as well as to assess the quality of management and operations and potential for the company to create shareholder value over time. The board should oversee corporate reporting and the policies and procedures underpinning the internal audit function and external audit.

A company’s financial reporting should provide decision-useful information for investors and other stakeholders on its financial performance and position. It should provide an accurate and balanced assessment of the risks and opportunities the company faces in realizing its long-term strategy. Accordingly, the assumptions made by management and reviewed by the auditor in preparing the financial statements should be reasonable and justified. Financial statements should be prepared in accordance with globally developed reporting standards and any divergence from generally accepted accounting principles should be explained in detail and justified. Accounting restatements should be explained in detail and any remedial actions, and the implications of these, disclosed.

In this context, audit committees play a vital role in a company’s financial reporting system by providing independent oversight of the accounts, material financial and, where appropriate to the jurisdiction, nonfinancial information, internal control frameworks and Enterprise Risk Management systems. In our view, effective audit committee oversight strengthens the quality and reliability of a company’s financial statements and provides an important level of reassurance to shareholders. Audit committees should have a procedure in place for assessing the independence of the auditor and the quality of the external audit process annually.

Similarly, material sustainability-related factors that are integral to how a company manages risks or generates revenue should be disclosed. In our view, the standards developed by the International Sustainability Standards Board, can be helpful to companies in preparing such reports(4).

Companies should establish robust risk management and internal control processes appropriate to the company’s business, risk tolerance, and regulatory environment. A credible whistleblowing system for employees, and potentially other stakeholders, can be a useful mechanism for ensuring that senior management and the board are aware of potential misconduct or breaches in risk management and internal control processes.

A comprehensive audit conducted by an independent audit firm contributes to investor confidence in the quality of corporate reporting. It is helpful when the audit report gives some insight into the scope and focus of the audit, as well as any critical audit matters identified and how these were resolved. A comprehensive and effective audit is time and resource intensive, and the audit fee should be commensurate. Fees paid to the audit firm for non-audit consulting should not exceed the audit fee to a degree that may prompt concerns about the independence of the audit. The audit committee should explain its position on auditor tenure and how it confirmed that the auditor remained independent.

(4)

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

A-11

We may vote against the election of the responsible directors if corporate reporting is insufficient or there are material misstatements in financial reports. In markets where relevant, we may vote against a proposal to approve the financial statements or the discharge of the board when we are concerned about the quality of the reporting or the audit. We may vote against proposals to appoint the auditor, ratify the audit report, or approve the audit fee if we are concerned about the auditor’s independence, the quality of the audit, or there are material misstatements in financial reports and the board has not established reasonable remediation plans.

Shareholder rights and protections

General shareholder meetings

Companies normally have an annual general meeting of shareholders at which routine and non-routine items of business are discussed and voted on by shareholders in attendance or submitting proxy votes. Companies should disclose materials relevant to the shareholder meeting sufficiently in advance so that shareholders can take them into consideration in their voting decisions. Many companies offer shareholders the option of participating in the meeting virtually which, whilst welcome, should not limit the rights of shareholders to participate as they would during an in-person meeting.

We may vote against directors when materials related to the business of the shareholder meeting are not provided in a timely manner or do not provide sufficient information for us to take an informed voting decision. We may vote against directors if the format of the shareholder meeting does not accommodate reasonable shareholder participation.

Bylaw amendments

We review bylaw amendments proposed by management on a case-by-case basis and will generally support those that are aligned with the interests of minority shareholders. Any material changes to the bylaws should be explained in detail and put to a shareholder vote.

We may vote against bylaw amendments that reduce shareholder rights and protections. We may vote against directors if material changes are made to the bylaws without shareholder approval.

If not provided for in the relevant corporate law, company bylaws should allow shareholders, individually or as a group, with a meaningful shareholding the right to call a special meeting of shareholders. The shareholding required to exercise this right should balance its utility with the cost to the company of holding special meetings.

If not provided for in the relevant corporate law, company bylaws should allow shareholders, individually or as a group, with a meaningful shareholding the right to nominate directors to the company’s board. The threshold for this right should be set so that shareholders can exercise it without being unduly disruptive to the board’s own nomination process.

Whilst we would not use either of these rights ourselves, we see them as important accountability mechanisms. We may vote for a shareholder proposal seeking the addition of either of these provisions to a company’s bylaws.

Change of domicile

We generally defer to management on proposals to change a company’s domicile as long as the rationale for doing so is consistent with the company’s long-term strategy and business model and the related costs are immaterial.

We may vote against directors or a proposal to change a company’s domicile where it does not seem aligned with our clients’ financial interests.

Changes to a company’s purpose or the nature of its business

Plans to materially change the nature of a company’s business or its purpose should be disclosed and explained in the context of long-term strategy and business dynamics. Such changes may significantly alter an investor’s views on the suitability of a company for their investment strategy or portfolio.

Where relevant, we may vote against proposals to change a company’s purpose or the nature of its business if the board has not provided a credible argument for change.

A-12

Shareholder proposals

Shareholders in many markets, who meet certain eligibility criteria, have the right to submit proposals to the general shareholder meeting asking a company to take a particular course of action subject to the proposal being supported by a majority of votes cast at the meeting. The topics raised address a range of governance, social and environmental matters that may be relevant to a company’s business. Shareholder proposals are considered by many investors to be an escalation tool when a company is unresponsive to their engagement.

We vote on these proposals on a case-by-case basis. We assess the relevance of the topic raised to a company’s business and its current approach, whether the actions sought are consistent with shareholders’ interests, and what impact the proposal being acted upon might have on financial performance.

Our general approach where we have concerns about a company’s governance, disclosures or performance is to engage to understand the apparent difference in perspective. If we continue to believe the company is not acting in shareholders’ financial interests, we may vote against the election of directors. We may support a relevant shareholder proposal if doing so reinforces the points made in our engagement or is aligned with our clients’ financial interests. We generally do not support shareholder proposals that are legally binding on the company, seek to alter a company’s strategy or direct its operations, or are unrelated to how a company manages risk or generates financial returns.

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

Corporate political activities

We seek to understand how companies ensure that their direct and indirect engagement in the policy making process is consistent with their public statements on policy matters important to the company’s long-term strategy. The board should be aware of the approach taken to corporate political activities as there can be reputational risks arising from inconsistencies. Companies should, as a minimum, meet all regulatory disclosure requirements on political activities, and ideally, provide accessible and clear disclosures to shareholders on policy positions, public policy engagement activities and political donations. To mitigate the risk of inconsistencies, companies can usefully assess the alignment between their policy priorities and the policy positions of the trade associations of which they are active members and any engagements undertaken by trade associations on behalf of members.

Generally, this is an engagement matter, although we may support a relevant shareholder proposal, or vote against directors, where a company’s disclosures are insufficient, or it becomes public that there is a material contradiction in a company’s public policy positions and its policy engagement.

Sustainability, or environmental and social, considerations

We seek to understand how companies manage the risks and opportunities inherent in their business operations. In our experience, sustainability-related factors(5) that are relevant to a company’s business or material to its financial performance, are generally operational considerations embedded into day-to-day management systems. Certain sustainability issues may also inform long-term strategic planning, for example, investing in product innovation in anticipation of changing consumer demand or adapting supply chains in response to changing regulatory requirements.

We recognize that the specific sustainability-related factors that may be financially material or business relevant will vary by company business model, sector, key markets, and time horizon, amongst other considerations. From company disclosures and our engagement, we aim to understand how management is identifying, assessing and integrating material

(5)

By material sustainability-related risks and opportunities, we mean the drivers of risk and financial value creation in a company’s business model that have an environmental or social dependency or impact. Examples of environmental issues include, but are not limited to, water use, land use, waste management, and climate risk. Examples of social issues include, but are not limited to, human capital management, impacts on the communities in which a company operates, customer loyalty, and relationships with regulators. It is our view that well-managed companies will effectively evaluate and manage material sustainability-related risks and opportunities relevant to their businesses. Governance is the core means by which boards can oversee the creation of durable financial value over time. Appropriate risk oversight of business-relevant and material sustainability-related considerations is a component of a sound governance framework.

A-13

sustainability-related risks and opportunities into their business decision-making and practices. Doing so helps us undertake a more holistic assessment of a company’s potential financial performance and the likely risk-adjusted returns of an investment.

We may vote against directors or support a relevant shareholder proposal if we have concerns about how a company is managing or disclosing its approach to material sustainability-related risks that may impact financial returns.

Key stakeholders

In our view, companies should understand and take into consideration the interests of the various parties on whom they depend for their success over time. It is for each company to determine their key stakeholders based on what is material to their business and long-term financial performance. For many companies, key stakeholders include employees, business partners (such as suppliers and distributors), clients and consumers, regulators, and the communities in which they operate. Companies that appropriately balance the interests of investors and other stakeholders are, in our experience, more likely to be financially resilient over time.

Climate and decarbonization investment objectives

Certain active BlackRock funds have climate and decarbonization objectives in addition to financial objectives. Consistent with the objectives of those investment strategies, our stewardship activity in relation to the holdings in those funds differs in some respects from BAIS’ benchmark guidelines, which are described above. Specifically, for those funds’ holdings, we look to investee companies to demonstrate that they are aligned with a decarbonization pathway that means their business model would be viable in a low-carbon economy, i.e., one in which global temperature rise is limited to 1.5⁰C above pre-industrial levels. This approach is only taken following BlackRock receiving the explicit approval from the applicable fund board.

The decarbonization stewardship guidelines focus on companies which produce goods and services that contribute to real world decarbonization or have a carbon intensive business model and face outsized impacts from the low carbon transition, based on reported and estimated scopes 1, 2, and 3 greenhouse gas emissions. These companies should provide disclosures that set out their governance, strategy, risk management processes and metrics and targets relevant to decarbonization. These disclosures should include an explanation of the decarbonization scenarios a company is using in its near- and long-term planning, as well as its scope 1, scope 2 and material scope 3 greenhouse gas (GHG) emissions and reduction targets for scope 1 and 2 emissions. As with the BAIS benchmark policies, we consider the climate-risk reporting standard issued by the International Sustainability Standards Board, IFRS S2, a useful reference for such reporting.

Under these climate- and decarbonization-specific guidelines, BAIS may recommend a vote against directors or support for a relevant shareholder proposal if a company does not appear to be adequately addressing or disclosing material climate-related risks. We may recommend supporting shareholder proposals seeking information relevant to a company’s stated low-carbon transition strategy and targets that the company does not currently provide and that would be helpful to investment decision-making. As under the BAIS benchmark approach, the active portfolio managers are ultimately responsible for voting consistent with their investment mandate and fund objectives.

Appendix 1: How we fulfil and oversee our active investment stewardship responsibilities

Oversight

The Global Head of BAIS has primary oversight of and responsibility for the team’s activities, including voting in accordance with the BlackRock Active Investment Stewardship Global Engagement and Voting Guidelines (“the Guidelines”), which require the application of professional judgment and consideration of each company’s unique circumstances, as well as input from active investors. BAIS is independent from BlackRock Investment Stewardship in our engagement and voting activities, reporting lines, and oversight.

The Active Investment Stewardship Oversight Committee, comprised of senior representatives of the active investment, legal and risk teams, reviews and advises on amendments to BAIS’ Global Engagement and Voting Guidelines. The Committee also considers developments in corporate governance, related public policy, and market norms and how these might influence BAIS’ policies and practices. The Committee does not determine voting decisions, which are the responsibility of BAIS and the relevant active equity investors.

A-14

In addition, there is a standing advisory group of senior active investors who counsel BAIS on complex or high-profile votes before a recommendation is finalized and escalated to the portfolio managers with holdings in the company under consideration. This group also formally reviews any revisions to the Engagement and Voting Guidelines proposed by BAIS as part of its annual review.

BAIS carries out engagement with companies in collaboration with active investment colleagues, executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the Guidelines. BAIS also conducts research on corporate governance issues and participates in industry discussions to contribute to and keep abreast of important developments in the corporate governance field. BAIS may use third parties for certain of the foregoing activities and performs oversight of those third parties (see “Use and oversight of third-party vote services providers” below).

Voting guidelines and vote execution

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

When exercising voting rights, BAIS will normally vote on specific proxy issues in accordance with the Guidelines, although portfolio managers have the right to vote differently on their holdings if they determine doing so is more aligned with the investment objective and financial interests of clients invested in the funds they manage.

The Guidelines are not intended to be exhaustive. BAIS applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review. As such, the Guidelines do not indicate how BAIS will vote in every instance. Rather, they reflect our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots. The Guidelines are reviewed annually and updated as necessary to reflect changes in market practices, developments in corporate governance and feedback from companies and clients. In this way, BAIS aims to maintain policies that explain our approach to governance practices most aligned with clients’ long-term financial interests.

In certain markets, proxy voting involves logistical issues which can affect BAIS’ ability to vote such proxies, as well as the desirability of voting such proxies. These issues include, but are not limited to: i) untimely notice of shareholder meetings; ii) restrictions on a foreigner’s ability to exercise votes; iii) requirements to vote proxies in person; iv) “share-blocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); v) potential difficulties in translating the proxy; vi) regulatory constraints; and vii) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as share-blocking or overly burdensome administrative requirements.

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

Voting Choice

BlackRock offers Voting Choice, a program that provides eligible clients with more opportunities to participate in the proxy voting process where legally and operationally viable.

Voting Choice is currently available for eligible clients invested in certain institutional pooled funds in the U.S., UK, and Canada that use systematic active equity (SAE) and multi-asset strategies. In addition, institutional clients in separately managed accounts (SMAs) are eligible for BlackRock Voting Choice regardless of their investment strategies(6).

(6)

With Voting Choice, SMAs have the ability to select from a set of voting policies from third-party proxy advisers the policy that best aligns with their views and preferences. BlackRock can then use its proxy voting infrastructure to cast votes based on the client’s selected voting policy.

A-15

As a result, the shares attributed to BlackRock in company share registers may be voted differently depending on whether our clients have authorized BAIS to vote on their behalf, have authorized BlackRock to vote in accordance with a third-party policy, or have elected to vote shares in accordance with their own policy. Our clients have greater control over proxy voting because of Voting Choice. BlackRock does not disclose client information, including a client’s selection of proxy policy, without client consent.

Use and oversight of third-party vote services providers

Third-party vote services providers – or proxy research firms - provide research and recommendations on proxy votes, as well as voting infrastructure. As mentioned previously, BlackRock contracts primarily with the vote services provider ISS and leverages its online platform to supply research and support voting, record keeping, and reporting processes. We also use Glass Lewis’ research and analysis as an input into our voting process. It is important to note that, although proxy research firms provide important data and analysis, BAIS does not rely solely on their information or follow their voting recommendations. A company’s disclosures, our past engagements and voting, investment colleagues’ insights and our voting guidelines are important inputs into our voting decisions on behalf of clients.

Given the large universe of actively held companies, BAIS employs the proxy services provider to streamline the voting process by making voting recommendations based on BAIS’ voting guidelines when the items on a shareholder meeting agenda are routine. Agenda items that are not routine are referred back to BAIS to assess, escalate as necessary to the relevant portfolio managers and vote. BAIS reviews and can override the recommendations of the vote services provider at any time prior to the vote deadline. Both BAIS and the vote services provider actively monitor securities filings, research reports, company announcements, and direct communications from companies to ensure awareness of supplemental disclosures and proxy materials that may require a modification of votes.

BAIS closely monitors the third-party vote services providers we contract with to ensure that they are meeting our service level expectations and have effective policies and procedures in place to manage potential conflicts of interest. Our oversight of service providers includes regular meetings with client service teams, systematic monitoring of vendor operations, as well as annual due diligence meetings in accordance with BlackRock’s firmwide policies.

Conflicts management policies and procedures

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

•

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

•

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

•

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

•

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

•

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

•

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

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

•

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

•

Established a reporting structure that separates BAIS from employees with sales, vendor management, or business partnership roles. In addition, BlackRock seeks to ensure that all engagements with corporate issuers, dissident shareholders or shareholder proponents are managed consistently and without regard to BlackRock’s relationship with such parties. Clients or business partners are not given special treatment or differentiated access. BAIS prioritizes engagements based on factors including, but not limited to, our need for additional information to make a voting decision or our view on the likelihood that an engagement could lead to positive outcome(s) over time for the economic value of the company. Within the normal course of business, BAIS may engage directly with

A-16

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

•

Determined to engage, in certain instances, an independent third-party voting service provider to make proxy voting recommendations as a further safeguard to avoid potential conflicts of interest, to satisfy regulatory compliance requirements, or as may be otherwise required by applicable law. In such circumstances, the independent third-party voting service provider provides BlackRock with recommendations, in accordance with the Guidelines, as to how to vote such proxies. BlackRock uses an independent third-party voting service provider to make proxy voting recommendations for shares of BlackRock, Inc. and companies affiliated with BlackRock, Inc. BlackRock may also use an independent third-party voting service provider to make proxy voting recommendations for:

•

public companies that include BlackRock employees on their boards of directors

•

public companies of which a BlackRock, Inc. board member serves as a senior executive or a member of the board of directors

•

public companies that are the subject of certain transactions involving BlackRock Funds

•

public companies that are joint venture partners with BlackRock, and

•

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

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

Securities lending

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

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

In almost all instances, BlackRock anticipates that the potential long-term financial value to clients of voting shares would not warrant recalling securities on loan. However, in certain instances, BlackRock may determine, in our independent business judgment as a fiduciary, that the value of voting outweighs the securities lending revenue loss to clients and would therefore recall shares to be voted in those instances.

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

Reporting and vote transparency

BAIS is committed to transparency in the stewardship work we do on behalf of clients. We inform clients about our engagement and voting policies and activities through direct communication and disclosure on our website.

Introduction to BlackRock Investment Stewardship

BlackRock’s clients depend on us to help them meet their varied investment goals. We consider it one of our responsibilities to be an informed, engaged shareholder on their behalf, given the business decisions that companies make have a direct impact on our clients’ long-term investment outcomes and financial well-being. BlackRock Investment Stewardship (BIS) is a dedicated function within BlackRock, which is responsible for engaging with public companies on behalf of index strategies. Investment Stewardship is one of the ways we fulfill our fiduciary responsibilities as an asset manager to our clients. Our sole objective when conducting our stewardship program is to advance our clients’ long-term financial interests.(7)

BIS takes a long-term approach in our stewardship efforts, reflecting the investment horizons of the majority of our clients. BIS does this through:

Engaging with companies in a two-way dialogue to build our understanding of a company’s practices and inform our voting decisions.

(7)

BIS’ Benchmark Policies, and the vote decisions made consistent with these policies, take a financial materiality-based approach and are focused solely on advancing clients' financial interests. BIS’ Benchmark Policies– comprised of the BIS Global Principles, regional voting guidelines, and engagement priorities – apply to clients’ assets invested through index strategies and provide guidance on our position on common corporate governance matters. We take a globally consistent approach, while recognizing the unique markets and sectors in which companies operate. BlackRock offers a wide range of investment products and funds to support our clients’ unique and varied investment objectives. Other materials on the BIS website might also provide useful context.

Philosophy on investment stewardship

Sound governance is critical to the success of a company, the protection of investors’ interests, and long-term financial value creation. Research indicates that high-performing companies will effectively evaluate and address risks and opportunities relevant to their businesses, which supports durable, long-term financial value creation.(8)

Setting, executing, and overseeing strategy are the responsibility of management and the board. As one of many minority shareholders, BlackRock cannot – and does not try to – direct a company’s strategy or its implementation. Our role, on behalf of BlackRock’s clients as long-term investors, is to better understand how corporate leadership is managing material risks and capitalizing on opportunities to help protect and enhance the company’s ability to deliver long-term financial returns. We aim to take a globally consistent approach, while recognizing the unique markets and sectors in which companies operate.

Shareholder rights

Corporate law, regulations and listing rules in most markets establish certain fundamental rights attached to shareholding. Shareholders should have the right to:

•

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

•

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

•

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

To protect the interest of minority shareholders like BlackRock’s clients, BIS holds the view that shareholder voting rights should be proportionate to economic ownership—the principle of “one share, one vote” helps to achieve this balance.

Stewardship in practice

The assets BlackRock manages belong to our clients, which include public and private pension plans, insurers, official institutions, endowments, universities, charities, family offices, wealth managers, and ultimately, the individual investors that they serve. Through stewardship, we assess how companies are creating long-term financial value to serve our clients, many of whom are saving for long-term goals, such as retirement.

As shareholders of public companies, our clients have the right to vote on matters proposed by a company’s management or its shareholders. Voting is an important mechanism for investors to express support for, or concern about, a company’s performance and most of our clients authorize BlackRock to exercise this right on their behalf. For those clients, and as a fiduciary, BlackRock is legally required to make proxy voting determinations in a manner that is consistent with their investment objectives. BIS does this by casting votes in favor of proposals that, in our assessment, will promote stronger governance and better operating practices and, in turn, potentially enhance long-term shareholder value. Our vote decisions are informed by our in-depth analysis of company disclosures, engagement with boards and management teams, third-party research, and comparisons against a company’s industry peers.

BIS takes a constructive, long-term approach to our engagement with companies, reflecting the investment horizons of the majority of our clients. An engagement is a meeting between BIS and a company’s board and management that helps improve our understanding of the company’s business model and material risks and opportunities, to inform our voting

A-22

decisions on behalf of clients who authorize us to vote on their behalf. In these two-way conversations, we listen to and learn directly from company directors and executives and ask questions relevant to their business. Either a company or BIS can request an engagement. Many of the engagements are initiated by companies to discuss their long-term strategy, risk and opportunity set, and management’s plan to deliver financial returns through business cycles. The ongoing, multiyear nature of our engagements allows us to build strong relationships with company leadership and mutual understanding on key matters of corporate governance and the drivers of long-term financial performance.

Generally, we support the vote recommendations of the board of directors and management. In case of concerns, we typically raise these through dialogue with board members and management teams first. When we determine it is in our clients’ financial interests to convey concern to companies through voting, we do so in two forms: we might not support the election of directors or other management proposals, or we might not support management’s voting recommendation on a shareholder proposal.

Key themes

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

At a minimum, it is our view that companies should observe the accepted corporate governance standards in their domestic market,(9) and we ask that, if they do not, they explain how their approach better supports durable, long-term financial value creation.

These Principles cover seven key subjects:

•

Boards and directors

•

Auditors and audit-related issues

•

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

•

Executive compensation

•

Material sustainability-related risks and opportunities

•

Other corporate governance matters and shareholder protections

•

Shareholder proposals

Our regional and market-specific voting guidelines explain how these Principles inform our voting decisions in relation to common ballot items for shareholder meetings in those markets. Alongside the Principles and regional voting guidelines, BIS publishes our engagement priorities which reflect the five themes on which we most frequently engage companies, where they are relevant, as these can be a source of material business risk or opportunity. Collectively, these BIS policies set out the core elements of corporate governance that guide our investment stewardship program globally and within each market. The BIS policies are not prescriptive, applied on a pragmatic, case-by-case basis, taking into consideration a number of factors, including the sector, market, and business environment within which a company is operating.

Boards and directors

Companies whose boards are comprised of appropriately qualified, engaged directors with professional characteristics relevant to a company’s business enhance the ability of the board to add value and be the voice of shareholders in board discussions. A strong board gives a company a competitive advantage, providing valuable oversight and contributing to the most important management decisions that support long-term financial performance. As part of their responsibilities, board members have a fiduciary duty to shareholders to oversee the strategic direction, operations, and risk management of a company. This is why our investment stewardship efforts have always started with the performance of the board of directors, and why we see engagement with, and the election of, directors as one of our most important responsibilities. We engage, as necessary, with members of the board’s nominating and/or governance committee to assess whether governance practices

(9)

Our regional voting guidelines, which we publish on the BIS website, reflect these different market standards and norms. Depending on the market, generally accepted practice is informed by corporate law, market regulation, best practices, and industry initiatives, amongst other factors.

A-23

and board composition are appropriate given a company’s business model and we take into consideration a number of factors, including the sector, market, and business environment within which a company is operating.

We view it as good practice when the board establishes and maintains a framework of robust and effective governance mechanisms to support its oversight of the company’s strategy and operations consistent with the long-term economic interests of investors. There should be clear descriptions of the role of the board and the committees of the board and how directors engage with and oversee management. Disclosure of material risks that may affect a company’s long-term strategy and financial value creation, including material sustainability-related factors when relevant, is helpful for investors to appropriately understand and assess how effectively management is identifying, managing, and mitigating such risks.

We seek to understand management's long-term strategy and the milestones against which investors should assess its implementation. If any strategic targets are significantly missed or materially restated, we find it helpful when company disclosures provide a detailed explanation of the changes and an indication of the board's role in reviewing the revised targets. We look to the board to articulate the effectiveness of these mechanisms in overseeing the management of business risks and opportunities and the fulfillment of the company’s strategy.

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

Regular accountability through director elections

To ensure accountability for their actions on behalf of shareholders, directors should stand for election on a regular basis, ideally annually.(10) Annual director elections allow shareholders to reaffirm their support for board members and/or hold them accountable for their decisions in a timely manner. When board members are not elected annually, in our experience, it is good practice for boards to have a rotation policy to ensure that, through a board cycle, all directors have had their appointment re-confirmed, with a proportion of directors being put forward for election at each annual general meeting.

Effective board composition

Regular director elections also give boards the opportunity to adjust their composition in an orderly way to reflect developments in the company’s strategy and the market environment. In our view, it is beneficial for new directors to be brought onto the board periodically to refresh the group’s thinking, while supporting both continuity and appropriate succession planning. We consider the average overall tenure of the board and seek a balance between the knowledge and experience of longer-serving directors and the fresh perspectives of directors who joined more recently.

We encourage companies to regularly review the effectiveness of their board (including its size), and assess directors nominated for election in the context of the composition of the board as a whole. In our view, the company’s assessment should consider a number of factors, including each director’s independence and time commitments, as well as the breadth and relevance of director experiences and skillsets, and how these collectively contribute to the board's effectiveness in advising and overseeing management in delivering long-term financial returns.

Director independence — from management, significant shareholders, or other related parties – is a central tenet of sound corporate governance across markets.(11) We encourage boards to have a sufficient number of independent directors, free from conflicts of interest or undue influence, to ensure objectivity in the decision-making of the board and its ability to oversee management. We generally consider it good practice for independent directors to make a majority of the board, or in the case of controlled companies, at least one-third.

Common impediments to independence may include but are not limited to:

•

Current or recent employment at the company or a subsidiary

(10)

In most markets directors stand for re-election on an annual or triennial basis, as determined by corporate law, market regulation or voluntary best practice.

A-24

•

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

•

Interlocking directorships

•

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

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

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

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

It is in this context that we are interested in a variety of experiences, perspectives, and skillsets in the board room. We see it as a means of promoting diversity of thought to avoid “group think” in the board’s exercise of its responsibilities to advise and oversee management.

In assessing board composition, we take a case-by-case approach based on a company’s board size, business model, strategy, location and market capitalization. We look for companies to explain how their approach to board composition supports the company’s governance practices.

We note that in many markets, policymakers have set board gender diversity goals which we may discuss with companies, particularly if there is a risk their board composition may be misaligned. We ask boards to disclose, consistent with local laws, how diversity, including professional and personal characteristics, is considered in board composition, given the company’s long-term strategy and business model.(12)

Sufficient capacity

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

Auditors and audit-related issues

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

The accuracy of financial statements, inclusive of financial and non-financial information as required or permitted under market-specific accounting rules, is of paramount importance to BlackRock. Investors increasingly recognize that a broader

(12)

Personal characteristics may include, but are not limited to, gender; race/ethnicity; disability; veteran status; LGBTQ+; and national, Indigenous, religious, or cultural identity.

A-25

range of risks and opportunities have the potential to materially impact financial performance. Over time, we anticipate investors and other users of company reporting will increasingly seek to understand and scrutinize the assumptions underlying financial statements, particularly those that pertain to the impact of the transition to a low-carbon economy on a company’s business model and asset mix. We recognize that this is an area of evolving practice and note that international standards setters, such as the International Financial Reporting Standards (IFRS) Board and the International Auditing and Assurance Standards Board (IAASB), continue to develop their guidance to companies.(13)

In this context, audit committees, or equivalent, play a vital role in a company’s financial reporting system by providing independent oversight of the accounts, material financial and, where appropriate to the jurisdiction, non-financial information and internal control frameworks. Moreover, in the absence of a dedicated risk committee, these committees can provide oversight of Enterprise Risk Management systems.(14) In our view, effective audit committee oversight strengthens the quality and reliability of a company’s financial statements and provides an important level of reassurance to shareholders.

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

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

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

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

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

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

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

In principle, we disagree with the creation of a share class with equivalent economic exposure and preferential, differentiated voting rights. In our view, this structure violates the fundamental corporate governance principle of proportionality and results in a concentration of power in the hands of a few shareholders, thus disenfranchising other shareholders and amplifying any potential conflicts of interest. However, we recognize that in certain markets, at least for a period of time, companies may have a valid argument for listing dual classes of shares with differentiated voting rights. In our view, such companies should review these share class structures on a regular basis or as company circumstances change. Additionally,

Enterprise risk management is a process, effected by the entity’s board of directors, management, and other personnel, applied in strategy setting and across the enterprise, designed to identify potential events that may affect the entity, and manage risk to be within the risk appetite, to provide reasonable assurance regarding the achievement of objectives. Please see the Committee of Sponsoring Organizations of the Treadway Commission (COSO), “Enterprise Risk Management”, 2023.

they should seek shareholder approval of their capital structure on a periodic basis via a management proposal at the company’s shareholder meeting. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.

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

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

Executive compensation

In most markets, one of the most important roles for a company’s board of directors is to put in place a compensation structure that incentivizes and rewards executives appropriately. Executive compensation is an important tool used by companies to support long-term financial value creation. In our experience, well-structured compensation policies reward the successful delivery of strategic, operational, and/or financial goals, encourage an appropriate risk appetite, and align the interests of shareholders and executives through equity ownership.

We look for there to be a clear link between variable pay and operational and financial performance. Performance metrics should be stretching and aligned with a company’s strategy and business model. BIS does not have a position on whether companies should use sustainability-related criteria in compensation structures, but, where they are included, we look to companies to be as rigorous as they would be in setting other financial or operational targets. Long-term incentive plans should encompass timeframes that 1) are distinct from annual executive compensation structures and metrics, and 2) encourage the delivery of strong financial results over a period of years.

When designing, reviewing, and approving executive compensation policies, board compensation committees – or board members responsible for setting executive compensation – should carefully consider the company’s specific circumstances, such as its risk profile, the environment in which it operates, and the individuals the board is trying to attract, retain and incentivize. We look to the compensation committees to guard against contractual arrangements that would entitle executives to material compensation for early termination of their employment. Finally, pension contributions and other deferred compensation arrangements should be reasonable in light of market practices or the company’s business and executive compensation strategies.

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

We encourage boards to consider building clawback provisions into incentive plans such that companies could clawback compensation or require executives to forgo awards when compensation was based on faulty financial statements or deceptive business practices. We also favor recoupment from or the foregoing of the grant of any awards by any senior

A-27

executive whose behavior caused material financial harm to shareholders, material reputational risk to the company, or resulted in a criminal investigation, even if such actions did not ultimately result in a material restatement of past results.

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

BIS may convey concerns through not supporting management’s proposals to approve compensation, where they are on the agenda. We may also vote against members of the compensation committee or equivalent board members for poor compensation practices or structures.

Material sustainability-related risks and opportunities

It is our view that well-managed companies will effectively evaluate and manage material sustainability-related risks and opportunities relevant to their businesses.(15) As with all risks and opportunities in a company's business model, appropriate oversight of material sustainability considerations is a core component of having an effective governance framework that supports durable, long-term financial value creation.

Robust disclosure allows investors to effectively evaluate companies’ strategy and business practices related to material sustainability-related risks and opportunities. We find it helpful when companies’ disclosures demonstrate that they have a resilient business model that integrates material sustainability-related risks and opportunities into their strategy, risk management, and metrics and targets, including industry-specific metrics. The International Sustainability Standards Board (ISSB) standards, IFRS S1 and S2(16) may prove helpful to companies in preparing this disclosure. The standards build on the Task Force on Climate-related Financial Disclosures (TCFD) framework and the standards and metrics developed by the Sustainability Accounting Standards Board (SASB), which have both converged under the ISSB. We recognize that companies may phase in reporting aligned with the ISSB standards over several years. We also recognize that some companies may report using different standards, which may be required by regulation, or one of a number of voluntary standards. In such cases, we ask that companies highlight the metrics that are industry- or company-specific.

We note that climate and other sustainability-related disclosures often require companies to collect and aggregate data from various internal and external sources. We recognize that the practical realities of data collection and reporting may not line up with financial reporting cycles and companies may require additional time after their fiscal year-end to accurately collect, analyze, and report this data to investors. That said, while we do not prescribe timelines regarding when companies make these disclosures, we encourage them to produce climate and other sustainability-related disclosures sufficiently in advance of their annual meeting, to the best of their abilities to provide investors with time to assess the data and make informed decisions.

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

Climate and nature-related risk

In our view, the transition to a low-carbon economy is one of several mega forces reshaping markets.(17) Our research shows that the low-carbon transition is a structural shift in the global economy that will be shaped by changes in government policies, technology, and consumer and investor preferences, which may be material for many companies.(18) Yet the path to a low-carbon economy is uncertain and uneven, with different parts of the economy moving at different speeds. BIS recognizes that it can be challenging for companies to predict the impact of climate-related risk and opportunity on their businesses and operating environments. Many companies are assessing how to navigate the low-carbon transition while delivering long-term financial value to investors. At companies where these climate-related risks are material, we find it helpful when they publicly disclose, consistent with their business model and sector, how they intend to deliver long-term financial performance through the transition to a low-carbon economy, including where available, their transition plan.(19)

In our experience, disclosure consistent with the ISSB standards or the TCFD framework can help investors assess company-specific climate-related risks and opportunities, and inform investment decisions.(20) Such disclosures also provide investors with insights into how companies are managing the risks associated with climate change by managing their own carbon emissions or emissions intensities to the extent financially practicable. Recognizing the value of these disclosures, in some jurisdictions, like the U.K, large companies must disclose such climate-related financial information on a mandatory basis, while in other jurisdictions these disclosures are viewed as best practice in the market.

Consistent with the ISSB standards and the TCFD framework, we seek to understand, from company disclosures and engagement, the strategies companies have in place to manage material risks to, and opportunities for, their long-term business model associated with a range of climate-related scenarios. This includes a scenario in which global warming is limited to well below 2°C, considering ambitions to achieve a limit of 1.5°C, the temperature goal recently reaffirmed by G20 members as part of the 2024 Leader’s Declaration.(21)

These frameworks also contemplate disclosures on how companies are setting short-, medium- and long-term targets, ideally science-based where these are available for their sector, for scope 1 and 2 greenhouse gas emissions (GHG) reductions and to demonstrate how their targets are consistent with the long-term financial interests of their investors.

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

In addition to climate-related risks and opportunities, the management of nature-related factors is increasingly a component of some companies’ ability to generate durable, long-term financial returns for shareholders, particularly where a company’s

We have observed that more companies are developing such plans, and public policymakers in a number of markets are signaling their intentions to require them or already have requirements in place, such as Australia, Brazil, and the European Union. We view transition plans as a method for a company to both internally assess and externally communicate its long-term strategy, ambition, objectives, and actions to create financial value through the global transition towards a low-carbon economy. Transition plans are building momentum internationally, with increased focus from policy makers and supervisors, including in the EU, UK, G7, G20, and from the financial industry. While many initiatives across jurisdictions outline a framework for transition plans, there is no consensus on the key elements these plans should contain. We view useful disclosure as one that communicates a company’s approach to managing financially material business relevant risks and opportunities – including climate-related risks – to deliver long-term financial performance, which allows investors to make more informed decisions. While transition plans can be helpful disclosure, BIS does not make the preparation and production of transition plans a voting issue. BIS may engage companies that have chosen to publish a transition plan to understand their planned actions and resource implications.

We recognize that companies may phase in reporting aligned with the ISSB standards over several years, depending on local requirements. We also recognize and respect that some companies may report using different local standards, which may be required by regulation, or one of a number of voluntary standards. In such cases, we ask that companies disclose their rationale for reporting in line with the specific disclosure framework chosen and highlight the metrics that are industry- or company-specific.

strategy is heavily reliant on the availability of natural capital, or whose supply chains are exposed to locations with nature-related risks. We look for such companies to disclose how they manage any reliance and impact on, as well as use of, natural capital, including appropriate risk oversight and relevant metrics and targets, to understand how these factors are integrated into strategy. We will evaluate these disclosures to inform our view of how a company is managing material nature-related risks and opportunities. We rely on company disclosures when determining how to vote on shareholder proposals addressing natural capital issues. Our publicly available commentary provides more information on our approach to natural capital.(22)

Companies’ impact on their workforce, supply chains, and communities

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

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

Companies should articulate how they address material adverse impacts that could arise from their business practices and affect critical relationships with their stakeholders. We encourage companies to implement, to the extent appropriate, monitoring processes (often referred to as due diligence) to identify and mitigate potential adverse impacts and grievance mechanisms to remediate any actual adverse material impacts. In our view, maintaining trust within these relationships can contribute to a company’s long-term success.

Other corporate governance matters and shareholder protections

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

Corporate form

In our view, it is the responsibility of the board to determine the corporate form that is most appropriate given the company's purpose and business model.(23) Companies proposing to change their corporate form to a public benefit corporation or similar entity should put it to a shareholder vote if not already required to do so under applicable law. We appreciate when supporting documentation from companies or shareholder proponents proposing to alter the corporate form clearly explains how the interests of shareholders and different stakeholders would be impacted as well as the accountability and voting mechanisms that would be available to shareholders. We generally support management proposals if our analysis indicates that shareholders’ economic interests are adequately protected. Relevant shareholder proposals are evaluated on a case-by-case basis.

(22)

Given the growing awareness of the materiality of these issues for certain businesses, enhanced reporting on a company's natural capital dependencies and impacts would aid investors’ understanding. In our view, the final recommendations of the Taskforce on Nature-related Financial Disclosures (TNFD) may prove useful to some companies. We recognize that some companies may report using different standards, which may be required by regulation, or one of a number of other private sector standards. TNFD-aligned reporting is not a voting issue.

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

Shareholder proposals

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

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

When assessing shareholder proposals, we evaluate each proposal on its merit, considering the company’s individual circumstances and maintaining a singular focus on the proposal’s implications for long-term financial value creation. BIS’ evaluation considers whether a shareholder proposal addresses a material risk that, if left unmanaged, may impact a company’s long-term performance. We look for consistency between the specific request formally made in the proposal, the supporting documentation, and the proponents’ other communications on the issues. We also assess the company’s practices and disclosures and the costs and benefits to the company of meeting the request made in the proposal. We take into consideration a company’s governance practices and disclosures against those of their peers.

In our experience, it is helpful when companies disclose the names of the proponent or organization that has submitted or advised on the proposal.

We would not support proposals that we believe would result in over-reaching into the basic business decisions of the company, are unduly prescriptive or constraining on management. We take into consideration the legal effect of the proposal, as shareholder proposals may be advisory or legally binding depending on the jurisdiction, while others may make requests that would be deemed illegal in a given jurisdiction.

BIS is likely to support shareholder proposals that request disclosures that help us, as long-term investors on behalf of our clients, better understand the material risks and opportunities companies face and how they are managing them, especially where this information is additive given the company’s existing disclosures. We may also support shareholder proposals that are focused on a material business risk that we agree needs to be addressed and the intended outcome is consistent with long-term financial value creation.

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

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

BlackRock’s oversight of its investment stewardship activities

Oversight

BlackRock maintains advisory committees (Stewardship Advisory Committees), generally consisting of senior BlackRock index investment professionals and/or senior employees with practical boardroom experience. The Stewardship Advisory Committees review and advise on amendments to BIS regional proxy voting guidelines (the Guidelines). The advisory committees do not determine voting decisions, which are the responsibility of BIS.

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

A-31

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

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

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

Voting guidelines and vote execution

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

When exercising voting rights, BIS will normally vote on specific proxy issues in accordance with the Guidelines for the relevant market, as well as the Principles. The voting guidelines published for each region/country in which we vote are intended to summarize BlackRock’s general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. The Guidelines are not intended to be exhaustive. BIS applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review. As such, the Guidelines do not indicate how BIS will vote in every instance. Rather, they reflect our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots. The Guidelines are reviewed annually and updated as necessary to reflect changes in market practices, developments in corporate governance and feedback from companies and clients. In this way, BIS aims to maintain policies that explain our approach to governance practices most aligned with clients’ long-term financial interests. BIS analysts may exercise their professional judgment in determining how to vote if they conclude that the Guidelines do not cover the specific matter raised by a ballot item or that an exception to the Guidelines would be in the long-term economic interests of BlackRock’s clients.

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

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

Voting Choice

BlackRock offers Voting Choice a program that provides eligible clients with more opportunities to participate in the proxy voting process where legally and operationally viable.

A-32

Voting Choice is currently available for eligible clients invested in certain institutional pooled funds in the U.S., UK, Ireland, and Canada that utilize certain equity index investment strategies, as well as eligible clients in certain institutional pooled funds in the U.S., UK, and Canada that use systematic active equity (SAE) strategies. In addition, institutional clients in separately managed accounts (SMAs) continue to be eligible for BlackRock Voting Choice regardless of their investment strategies.(24) BlackRock also launched a U.S. Program to offer proxy voting to eligible shareholder accounts in a U.S. Fund.(25)

As a result, the shares attributed to BlackRock in company share registers may be voted differently depending on whether our clients have authorized BIS to vote on their behalf, have authorized BIS to vote in accordance with a third-party policy, or have elected to vote shares in accordance with their own policy. Our clients have greater control over proxy voting because of Voting Choice. BlackRock does not disclose client information, including a client’s selection of proxy policy, without client consent.

Conflicts management policies and procedures

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

•

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

•

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

•

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

•

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

•

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

•

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

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

•

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

•

Established a reporting structure that separates BIS from employees with sales, vendor management, or business partnership roles. In addition, BlackRock seeks to ensure that all engagements with corporate issuers, dissident shareholders or shareholder proponents are managed consistently and without regard to BlackRock’s relationship with such parties. Clients or business partners are not given special treatment or differentiated access to BIS. BIS prioritizes engagements based on factors including, but not limited to, our need for additional information to make a voting decision or our view on the likelihood that an engagement could lead to positive outcome(s) over time for the economic value of the company. Within the normal course of business, BIS may engage directly with BlackRock clients, business partners and/or third parties, and/or with employees with sales, vendor management, or business partnership roles, in discussions regarding our approach to stewardship, general corporate governance matters, client reporting needs, and/or to otherwise ensure that proxy-related client service levels are met

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

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

Securities lending

With regard to the relationship between securities lending and proxy voting, BlackRock cannot vote shares on loan and may determine to recall them for voting, as guided by our fiduciary duty as an asset manager to our clients in helping them achieve their investment goals. While this has occurred in a limited number of cases, the decision to recall securities on loan as part of BlackRock’s securities lending program in order to vote is based on an evaluation of various factors that include, but are not limited to, assessing potential securities lending revenue alongside the potential long-term financial value to clients of voting those securities (based on the information available at the time of recall consideration).(26) BIS works with colleagues in the Securities Lending and Risk and Quantitative Analysis teams to evaluate the costs and benefits to clients of recalling shares on loan.

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

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

Reporting and vote transparency

We are committed to transparency in the stewardship work we do on behalf of clients. We inform clients about our engagement and voting policies and activities through direct communication and through disclosure on our website. Additionally, we make public our regional proxy voting guidelines for the benefit of clients and the companies in which we invest on their behalf. We also publish commentaries to share our perspective on market developments and emerging key themes.

At a more granular level, on a quarterly basis, we publish our vote record for each company that held a shareholder meeting during the period, showing how BIS voted on each proposal and providing our rationale for any votes against management proposals and on shareholder proposals. For shareholder meetings where a vote might be high profile or of significant

(26)

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

A-34

interest to clients, we may publish a vote bulletin after the meeting, disclosing and explaining our vote on key proposals. We also publish a quarterly list of all companies with which we engaged and the key topics addressed in the engagement meeting.

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

BlackRock Investment Stewardship

Climate and Decarbonization Stewardship Guidelines

Published July 2024

BlackRock climate and decarbonization stewardship guidelines

Introduction to BlackRock Investment Stewardship

BlackRock’s clients depend on us to help them meet their varied investment goals. We consider it one of our responsibilities to be an informed, engaged shareholder on their behalf, given the business decisions that companies make have a direct impact on our clients’ long-term investment outcomes and financial well-being. BlackRock Investment Stewardship (BIS) is a dedicated function within BlackRock, which serves as a link between BlackRock’s clients and the companies we invest in on their behalf. BIS takes a long-term approach in our stewardship efforts, reflecting the investment horizons of the majority of our clients. BIS does this through:

Engaging with companies in a two-way dialogue to build our understanding of a company’s practices and inform our voting decisions.

Voting at shareholder meetings on management and shareholder proposals on behalf of clients who have delegated voting authority to BlackRock.

Contributing to industry dialogue on stewardship to share our perspectives on matters that may impact our clients’ investments.

Reporting on our activities to inform clients about our stewardship efforts on their behalf through a range of publications and direct reporting.

Stewardship for clients with investment objectives relating to the low-carbon transition

BlackRock offers a wide range of investment products and funds to support our clients’ unique and varied investment objectives, and in February 2024, BlackRock announced it would be launching a new decarbonization stewardship option for those clients who explicitly direct BlackRock to invest their assets with decarbonization investment objectives. An increasing number of clients are seeking to minimize the financial risk, and maximize the financial opportunities, associated with the transition to a low-carbon economy, and thus are interested in sustainable and transition investing, with some including decarbonization as an investment objective in their mandates with BlackRock. In Europe for example, all of our largest, strategic relationship clients have net zero commitments for their organizations, and globally a growing number have made similar commitments, which those clients believe, will shape financial opportunities in the transition to a low-carbon economy. A survey of 200 institutional investors globally, representing nearly $9tn in assets under management, indicated that 98% of them have set some kind of transition investment objective for their portfolios.

These guidelines set out BIS’ approach to voting at companies’ shareholder meetings on behalf of funds with explicit decarbonization or climate-related investment objectives, and, when appropriate, engagement with corporate leadership to support our voting on clients’ behalf. In addition, clients in separately managed accounts may instruct BlackRock to apply these guidelines to their holdings. Both in the case of funds and separately managed accounts, these guidelines are only implemented upon explicit selection and approval by the applicable fund board or client.

These guidelines should be read in conjunction with BIS’ benchmark policies and are focused on matters related to climate risks and the transition to a low-carbon economy at companies that are held by funds and clients who have selected these guidelines. These guidelines differ from the benchmark policies in that they consider, in addition to financial considerations and consistent with the investment objective of each fund or account that has selected these guidelines, the alignment of companies’ business model and strategies with the financial opportunities presented by the transition to a low-carbon economy and the more ambitious goal of the Paris Agreement, namely to limit average temperature rise to 1.5°C above pre-industrial levels.

These guidelines will apply to companies which produce goods and services that contribute to real world decarbonization or have a carbon intensive business model and face outsized impacts from the low-carbon transition, based on reported and estimated scopes 1, 2, and 3 greenhouse gas emissions. We estimate these companies represent the vast majority of the

A-36

value chain emissions of the companies held by funds and clients that have selected these guidelines. For all other companies held by these funds and clients, BIS’ benchmark voting guidelines apply.

On other matters not related to climate risks and the transition to a low-carbon economy, BIS will apply our benchmark policies.

For clients who have not directed BlackRock to prioritize climate risks and decarbonization as an investment objective, BIS will continue to undertake our stewardship responsibilities in line with our benchmark policies, with a sole focus on advancing those clients’ long-term economic interests. This will include consideration of climate-related risks and opportunities in a company’s business model, where material to the company’s ability to deliver long-term financial returns.

Please see appendix 2, which sets out the key differences between the BIS benchmark and decarbonization policies on items related to climate risk and the transition to a low-carbon economy.

Understanding the investment implications of the transition to a low-carbon economy

Research from the BlackRock Investment Institute (BII) highlights that changing government policy, technology, and consumer and investor preferences are driving the transition to a low-carbon economy, but these forces are moving at uneven speeds across sectors and regions. For example—some technologies like renewable power are already being deployed at scale in some regions, while in other sectors and regions less cost-effective low-carbon alternatives exist. We have heard from certain clients that they see the low-carbon transition as a series of shifts over decades that will reshape production and consumption, spur significant capital investment and create risks, opportunities and a wider range of financial and competitive outcomes for companies.

For clients interested in investing in the transition to a low-carbon economy and understanding its corresponding risks and opportunities, we have developed the BlackRock Investment Institute Transition Scenario (BIITS), powered by Aladdin® technology. BIITS is a research-based, analytical forecast of how the low-carbon transition is most likely to play out based on what we know and expect today. It can help inform a top-down assessment of a company’s business risk arising from the transition. BII based its key assumptions on rigorous research, and the input of BlackRock’s portfolio managers and other experts.

For client assets with explicit investment objectives related to the transition to a low-carbon economy, BIS will draw on the insights generated by BIITS and Aladdin® Climate, as well as our own analysis and engagement, in applying these guidelines. In doing so, we will take into consideration the fact that the necessary data to assess individual companies currently has limitations, but is improving as a result of disclosure requirements in an increasing number of jurisdictions.

Decarbonization stewardship guidelines design principles

The framework of these guidelines is designed to:

•

Prioritize sectors and companies that are critical to the transition to a low-carbon economy: This includes companies which produce goods and services that contribute to real world decarbonization or have a carbon intensive business model and face outsized impacts from the low-carbon transition.

•

Apply a sectoral approach to our analysis that acknowledges the unevenness of the low-carbon transition across sectors and markets: We take into consideration the varying speeds at which sectors and markets can decarbonize based on technological feasibility, consumer demand, government policy, regulatory frameworks and other factors. Further, we recognize that these factors are uncertain and dynamic, which will require that we evolve our approach as necessary.

•

Take a long-term, pragmatic approach that favors a transition that minimizes disruption to companies and their key stakeholders: Our approach recognizes the challenges that many companies face in adapting their business models. It is premised on the views of interested clients that a transition where companies adapt and continue to deliver financial returns throughout, is a better long-term investment outcome for them, and less disruptive to a company’s other key stakeholders, than a transition that is uneven. Further, we consider the differences between the actions and outcomes over which company management has influence, and those it does not.

•

Focus on useful, contextualized disclosures that help inform investors views, while recognizing data limitations: The policy will seek disclosures that outline key milestones and dependencies underpinning the company’s low-carbon transition strategy; explain the trade-offs required to adapt the business model; and include relevant data and narrative.

A-37

•

Be consistent with our position as a minority investor on behalf of our clients: The boards and executive leadership of companies determine a company’s strategy and its implementation. We make decisions on how to engage companies and vote proxies independently, based on our professional judgment of the priorities and outcomes most aligned with clients’ investment objectives.

Voting guidelines

Consistent with the investment objective of each fund or client that has selected these guidelines, BIS will look to companies to demonstrate the following:

Corporate Disclosures

In the context of these guidelines, we look for companies to provide sufficient corporate disclosure to allow us to determine the extent to which decarbonization and the low-carbon transition are strategic priorities. As a general point, we would expect companies that have disclosed their aim to participate in the transition to a low-carbon economy to make disclosures that help explain the strategy and governance systems they have determined most appropriate, which may include:

(1)

a low-carbon transition strategy to demonstrate their alignment with the ambition to limit global average temperature rise to 1.5°C above pre-industrial levels. This would normally mean that they have a long-term strategy to achieve net-zero greenhouse gas (GHG) emissions by 2050, with appropriate near- and medium-term milestones to assess their progress.

(2)

low-carbon transition-related reporting consistent with the standards developed by the International Sustainability Standards Board (ISSB). IFRS S1 addresses the general requirements of sustainability reporting and IFRS S2 sets out the disclosures that would provide investors with decision-useful information about a company’s most significant climate- and low-carbon transition-related risks and opportunities. As audit and assurance standards are developed, it would be helpful to investors’ confidence in such disclosures for companies to seek independent, third-party assurance.

(3)

scope 1 and scope 2, and material scope 3 GHG emissions. In addition, we look to companies to disclose their reduction targets for scope 1 and 2 emissions, science-based where possible. We welcome disclosure of targets or indicative goals, where companies have set them, for scope 3 emissions reductions, recognizing that these would be provided on a ‘best efforts’ basis given the methodological challenges these currently present for reporters. Scope 3 information, including how a company is working with its value chain to accelerate reductions in GHG intensity, provides useful insight to investors focused on investing in the low-carbon transition and understanding the impact of their investments on their decarbonization goals. However, we recognize that companies have varying ability to influence the emissions across the different parts of their value chain and it is helpful when disclosures explain the implications for the achievement of their decarbonization targets.

Transition plans

Some companies have published a transition plan that explains how the company intends to implement its low-carbon transition strategy by, as defined by the ISSB, “lay[ing] out the entity’s targets, actions or resources for its transition towards a lower-carbon economy, including actions such as reducing its greenhouse gas emissions” (see appendix 1).

We note the work being undertaken in a number of jurisdictions on establishing a common approach in a market to corporate transition plans. Given this work continues, for the near-term, BIS will not make preparation and production of transition plans a voting issue. BIS may engage companies that have chosen to publish a transition plan to understand their planned actions and resource implications in accordance with anticipated requirements.

Boards and directors

An effective and well-functioning board that has appropriate governance structures to facilitate oversight of a company's management and strategic initiatives is critical to the company’s ability to deliver on its low-carbon transition strategy.

In assessing the role and effectiveness of the board in this regard, we seek to understand whether:

•

The board has clear oversight responsibilities for climate and low-carbon transition-related risks and opportunities in the company’s business model. We consider the whole board to have responsibility for oversight of the company’s long-term strategy, including those aspects related to the transition to a low-carbon economy.

A-38

•

Management has established a robust low-carbon transition framework and long-term strategy, with clear accountability for delivery by senior executives.

•

The capital management strategy explains how the company allocates investments to (traditional and next generation) business lines and innovation, and returns cash to shareholders, consistent with the low-carbon transition strategy.

•

The climate and low-carbon transition risks most likely to significantly impact the business are integrated into the company’s enterprise risk management processes and reporting.

•

The company has set scope 1 & 2 GHG emissions reduction targets, science-based and independently verified where possible, against a baseline, that are consistent with the ambition to limit average temperature rise to no more than 1.5°C above pre-industrial levels.

•

There is a clear link between the company’s scope 1 & 2 GHG emissions reduction targets over time and its long-term low-carbon transition strategy.

•

The company is monitoring its material scope 3 emissions and disclosing these where it is confident in the data. Given forthcoming regulatory requirements in certain jurisdictions, some companies are voluntarily disclosing scope 3 emissions reductions targets and plans, setting out how they are working on decarbonization with the different constituents in their value chain.

•

The board oversees, and management has a formalized approach to, the company’s lobbying activities, including trade association memberships. Policy engagement should be consistent with a company’s stated strategic policy objectives, including those related to the low-carbon transition.

Voting against directors over concerns about climate risk

In implementing these guidelines, BIS will generally support non-executive directors standing for election where, in BIS’ assessment based on company disclosures and engagement, a company is executing on its commitment to align with the transition to a low-carbon economy, as defined above. Where BIS determines this is not the case, we may vote against the election of one or more directors who have responsibility for the issue. The directors most likely to be in focus are the chair of the board sub-committee with low-carbon transition, climate or sustainability risk oversight responsibilities, other members of the relevant committee, the lead independent director or the non-executive chair of the board. In certain markets, we may withhold support for the discharge of the supervisory board or equivalent.

Where we have not supported director elections over climate concerns in a prior year, and the company has not subsequently made progress towards aligning with the transition to a low-carbon economy, we may escalate by voting against the re-election of additional responsible directors to signal our heightened concerns.

Management proposals to approve a climate strategy or progress report

In certain markets, company management may submit proposals asking shareholders to approve their climate action plans or progress reports, sometimes known as “Say on Climate.” BIS will generally support management’s climate strategy proposal if, in our assessment based on these guidelines, the strategy is aligned with the low-carbon transition. Similarly, we will generally support management’s proposal on a progress report if the company has clearly explained its progress against, and any deviations from or changes to, its stated transition plan and targets.

Shareholder proposals on climate and low-carbon transition matters

Shareholder proposals on a company’s approach to the low-carbon transition or climate risk will be considered on their merit. Our assessment will take into consideration the implications for, and the relevance to, the company’s stated low-carbon transition strategy and targets. We may support shareholder proposals that, for example, ask a company to:

•

Publish a business plan, and related disclosures, consistent with the ambition to limit average temperature rise to no more than 1.5°C above pre-industrial levels

•

Align their scope 1 and 2 GHG emissions reduction targets to, and/or discuss how their targets align with, a long-term goal of the company achieving net zero GHG emissions by 2050

•

Disclose the categories of scope 3 GHG emissions most material to a company’s business model

•

Improve disclosures on how a company’s climate-related lobbying (including trade association memberships and other indirect lobbying) is aligned with its strategic policy positions.

A-39

We would not support shareholder proposals that seek to constrain board or management decision-making or direct specific business or strategic decisions. This includes proposals that seek to change a company’s articles of association or charter to require commitments or actions related to climate risk or the low-carbon transition.

Related matters

There are other business items not covered above that may be put to a shareholder vote that could address matters relevant to the transition to a low-carbon economy. Under these guidelines, BIS is most likely to engage, where appropriate, if we seek to enhance our understanding of a company’s approach. Generally, our voting on these matters would be covered by BIS’ benchmark guidelines.

Executive compensation

We look to company boards to put in place a compensation structure that incentivizes and rewards executives appropriately. Some companies, in light of their long-term strategy, may decide to include relevant GHG emissions reduction targets or low-carbon transition-related metrics in their incentive plans. In such cases, BIS would engage to understand the alignment between those metrics and the company’s stated climate strategy.

Auditors and audit-related issues

For companies with material climate or transition risks or opportunities in their business models, BIS is interested to understand whether the company considers and, if relevant, quantifies, and accounts for material climate-related risks in its financial statements, including if the company explains such risks within the context of its audit report. We note that work is being undertaken to develop audit and assurance standards in relation to climate and transition reporting, which may impact the future reporting requirements of companies. We note that assurance of corporate disclosures related to climate risk and the transition to a low-carbon economy is still nascent.

Mergers, acquisitions, asset sales, and other special situations

Special situations will be considered on their financial merits, but BIS may engage on climate-related factors under these guidelines where a transaction may significantly alter a company’s climate strategy or a shareholder activist has proposed governance, strategic or operational changes that may impact its climate strategy. BIS does not promote changes in corporate control, nor does it invoke formal governance mechanisms that rise to the level of shareholder activism.

Other business relevant sustainability-related risks and opportunities

Climate risk and the transition to a low-carbon economy are interconnected with a number of other sustainability-related risks and opportunities that may be relevant to a company’s business model and long-term performance. These include a company’s impacts or dependencies on natural capital and key stakeholders. In the context of these guidelines, we may engage companies to better understand how they are managing the impact on people (e.g., employees, suppliers, customers and communities) of any strategic or operational changes they are making in relation to their transition to a low-carbon economy. Similarly, we may engage companies that face risks and opportunities related to land use and deforestation, access to fresh water, or the ability to secure scarce resources critical to the transition to a low-carbon economy.

Appendix 1

Terminology

We understand the key concepts referred to within these guidelines as follows:

Climate risk: Includes physical risk, the increased risk to companies’ assets and activities caused by the direct impact of changing weather patterns and natural catastrophes, and transition risk, the impact of the transition to a low-carbon economy on a company’s long-term profitability.

Transition to a low-carbon economy (“low-carbon transition”): The global economic shift toward lower emissions across many sectors and business models. The economic transformation is being driven by changes in government policy, technology, and consumer and investor preferences, as well as the physical effects of climate change (e.g., extreme weather), and can potentially have a material impact on clients’ investments and portfolios.

A-40

Decarbonization: the process of reducing or eliminating emissions of carbon dioxide (CO2) from human activity and removing carbon currently in the atmosphere. This can be carried out by countries, companies and even individual consumers. Sometimes the concept is understood to include the reduction and elimination of other GHG, e.g., methane.

Climate-related risks and opportunities: The investment opportunities and risks associated with the transition to a low-carbon economy, including transition risks and opportunities and physical risks and opportunities in adapting to physical climate change.

Climate-related transition plan: “An aspect of an entity’s overall strategy that lays out the entity’s targets, actions or resources for its transition towards a lower-carbon economy, including actions such as reducing its greenhouse gas emissions.”

Science-based GHG emissions reduction targets: Targets that “…are in line with what the latest climate science deems necessary to meet the goals of the Paris Agreement – limiting global warming to 1.5°C above pre-industrial levels. Science-based targets give companies a clearly defined path to reduce greenhouse gas emissions in line with limiting global warming to 1.5°C. They define how much and how quickly a business must reduce its emissions to be in line with the Paris Agreement goals.”

Fund	Ticker	Listing Exchange
iShares Commodity Curve Carry Strategy ETF (the “Fund”)	CCRV	NYSE Arca

iShares® and BlackRock® are registered trademarks of BlackRock Fund Advisors and its affiliates.

General Description of the Trust and the Fund

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a specified amount of cash. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca” or “Listing Exchange”), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for a specified amount of cash. Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

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

Exchange Listing and Trading

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

Investment Strategies and Risks

The Fund seeks to achieve its investment objective primarily by investing in total return swaps that provide exposure to commodities futures contracts referenced by the Underlying Index. The Fund operates as an index fund and is not actively managed. Adverse performance of an instrument in the Fund's portfolio will ordinarily not result in the elimination of the instrument from the Fund's portfolio.

The Fund through its Subsidiary (as defined below) will invest in financial instruments that provide exposure to commodities, and not in the physical commodities themselves. Although the Fund reserves the right to invest in a broad range of financial instruments, the Fund expects to obtain a substantial amount of its exposure to the carry strategy by entering into total return swaps that provide returns similar to the commodity futures contracts referenced in the Underlying Index.

As of October 31, 2024, the Underlying Index universe is currently composed of 12 futures contracts on physical agricultural, energy, precious metals, and industrial metals commodities listed on U.S. and non-U.S. futures exchanges. The Underlying Index is rebalanced on a monthly basis to include the 10 commodity futures contracts representing the underlying commodities with the largest global production value, where more weight in the Underlying Index is given to those contracts having the highest degree of backwardation or lowest degree of contango (i.e., those with the highest “positive carry,” as explained below) among the Underlying Index universe.

In order to maintain exposure to a futures contract on a particular commodity, an investor must sell the position in the expiring contract and buy a new position in a contract with a later delivery month, which is referred to as “rolling.” If the price for the new futures contract is less than the price of the expiring contract, then the market for the commodity is said to be in “backwardation.” In these markets, investors experience positive roll returns, which is referred to as “positive carry.” The term “contango” is used to describe a market in which the price for a new futures contract is more than the price of the expiring contract. In these markets, investors experience negative roll returns, which is referred to as “negative carry.” The Underlying Index seeks to employ a positive carry strategy that emphasizes commodities and futures contract months with the greatest degree of backwardation and lowest degree of contango, resulting in net gains through positive roll returns.

The Fund is expected to establish new total return swap contracts on an ongoing basis and replace expiring contracts. The Underlying Index is rebalanced on a monthly basis and could contain more than 10 contracts during the rebalancing period. Total return swaps subsequently acquired by the Fund may have terms that differ from the swaps the Fund previously held. The Fund generally expects to pay a fixed payment rate and swap-related fees to each counterparty and receive the total return of the Underlying Index, including, in the event of negative performance by the Underlying Index, a negative return (i.e., a payment from the Fund to the swap counterparty).

The Fund also seeks to generate interest income and capital appreciation on the cash balances arising from its investment in Commodity Investments (as defined below) through a cash management strategy consisting primarily of investments in cash and cash equivalents, short-term government obligations, and short-term fixed-income securities (collectively, “Fixed-Income Investments”). The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s investments in derivatives on a day-to-day basis.

The Fund may also invest in swaps on commodity futures contracts that are not included in the Underlying Index but provide exposure to commodities from the same sectors as those found in the Underlying Index, as well as in futures, options and forwards that provide exposure to commodities from such sectors (collectively with total return swaps on the Underlying Index, the “Commodity Investments”). The Fund will invest in Commodity Investments solely through its Subsidiary. INVESTING IN DERIVATIVE CONTRACTS MAY HAVE A LEVERAGING EFFECT ON THE FUND BECAUSE OF THE LEVERAGE INHERENT IN THE USE OF DERIVATIVES.

The Fund seeks to gain exposure to Commodity Investments by investing through a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Subsidiary invests solely in Commodity Investments and cash and cash equivalents.

The remainder of the Fund’s assets will be invested directly by the Fund, primarily in Fixed-Income Investments, including repurchase agreements, money market instruments, U.S. government and agency securities, sovereign debt obligations on non-U.S. countries (excluding emerging market countries), commercial paper, non-convertible corporate debt securities, and obligations of U.S. and non-U.S. banks and similar institutions.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject the adviser of a registered investment company to regulation by the CFTC if such registered investment company invests more than a prescribed level of its net asset value in commodity interests, including futures, options and swaps, or if the registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of commodity interests above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”).

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

taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

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

Derivatives. The Fund will use instruments referred to as derivatives. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), a currency or an index (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). Derivatives allow the Fund to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. The Fund may use derivatives for hedging purposes. The Fund may also use derivatives for speculative purposes to seek to enhance returns or as a vehicle to obtain investment exposure to a commodity or index. The use of a derivative is speculative if the Fund is primarily seeking to achieve gains, rather than to offset the risk of other positions. When the Fund invests in a derivative for speculative purposes, the Fund will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. Unless otherwise permitted, the Fund may not use any derivatives to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly.

Diversification Status. The Fund is classified as “non-diversified.” A non-diversified fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may constitute a significant percentage of the investment portfolio of such a fund. This may adversely affect the fund’s performance or subject the fund’s shares to greater price volatility than that experienced by more diversified investment companies.

rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Fund’s ability to terminate existing securities lending agreements or to realize amounts to be received under such agreements. Prudential regulation may also favor lenders that can provide additional protections, such as liens that are exercisable in connection with a lender default, to borrowers. The Fund may provide additional protections to borrowers, where permitted pursuant to the Fund’s investment policies and if BFA believes doing so is in the best interest of the Fund.

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

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”) or (ii) markets itself as providing investment exposure to such instruments. Due to the Fund's potential use of CFTC Derivatives above the prescribed levels, the Fund and the subsidiary will each be considered a “commodity pool” under the CEA. Accordingly, BFA, the Fund’s investment adviser, has registered as a commodity pool operator and is subject to CFTC regulation with respect to the Fund. BFA is also subject to regulation by the National Futures Association.

securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and the Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of the Fund’s assets. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by the Fund through reverse repurchase agreements may be invested in additional securities.

Sovereign and Quasi-Sovereign Obligations. The Fund may invest in sovereign and quasi-sovereign obligations. An investment in sovereign debt obligations involves special risks not present in corporate debt obligations. Sovereign debt includes securities issued or guaranteed by a foreign sovereign government. Quasi-sovereign debt includes securities issued or guaranteed by an entity affiliated with or backed by a sovereign government. Quasi-sovereign debt obligations are typically less liquid and less standardized than sovereign debt obligations. The issuer of the sovereign debt that controls the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. Similar to other issuers, changes to the financial condition or credit rating of a non-U.S. government may cause the value of a sovereign debt to decline. During periods of economic uncertainty, the market prices of sovereign debt obligations may be more volatile than prices of U.S. debt obligations, which may affect the Fund's NAV. Several sovereign issuers have experienced volatility and adverse trends due to concerns about rising government debt levels, including Greece, Ireland, Italy, Portugal and Spain.

A sovereign debtor's willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its non-U.S. currency reserves, the availability of sufficient foreign exchange, the relative size of the debt service burden, the sovereign debtor's policy toward principal international lenders and local political constraints. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies and other entities to reduce principal and interest arrears on their debt. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the sovereign debtor, which may further impair such debtor's ability or willingness to service its debts. Quasi-sovereign debt obligations are typically less liquid and less standardized than government debt.

The Fund may enter into commodity and index swap agreements. The use of such swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus.

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

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument typically is based upon the price movements of a commodity or an economic variable linked to such price movements. Therefore, the value of commodity-linked derivative instruments may be affected by changes in overall economic conditions, in interest rates, or factors affecting a particular commodity or industry, such as production, disease, climate conditions, supply or demand, politics, geopolitics, changes in international balance of payments and trade, currency devaluations and revaluations, market liquidity, and economic and regulatory developments. The prices of commodity-related investments may fluctuate quickly and dramatically and may or may not correlate to price movements in other asset classes, such as stocks, bonds and cash. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop. Commodity derivatives are subject to the risk that the counterparty to the transaction may default or otherwise fail to perform. The Fund’s use of commodity-linked derivatives can result in large amounts of financial leverage. Although the Fund will not borrow money in order to increase the amount of its trading, the low margin deposits normally required in futures trading permit a high degree of leverage on the investment itself. Accordingly, a relatively small price movement in a futures contract may result in immediate and substantial losses to the Fund. Like other leveraged investments, any trade may result in losses in excess of the amount invested. These factors and events could have a significant negative impact on the Fund.

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

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

relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit.

crude oil, natural gas, and other commodities. As a result, an increase in demand for, or price fluctuations of, certain commodities may negatively affect developed country economies. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries. In addition, heavy regulation of, among others, labor and product markets may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Such risks, among others, may adversely affect the value of the Fund’s investments.

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

activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, may impact Russia's economy, Russian issuers of securities in which the Fund invests, or the economies of Europe as a whole. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors across Europe and globally.

Factors that may cause a change in the price of gold, include, among other things:

•

Changes in the supply and demand of goods or services of large users of gold. For example, as demand for consumer goods such as jewelry and electronics increases, the price of gold can rise.

•

The frequency and magnitude of such changes cannot be predicted.

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

Construction and Maintenance of the Underlying Index

A description of the Fund's Underlying Index is provided below.

The ICE BofA Commodity Enhanced Carry Total Return Index

Number of Components: approximately 12

Index Description. The ICE BofA Commodity Enhanced Carry Total Return Index measures the performance of a long-only basket of liquid commodity futures contracts representing the underlying commodities with the largest global production value, where the weights of selected contracts are tilted towards those having a high positive carry.

Index Methodology. The Index’s constituent contracts and weights are determined based on a methodology established by the ICE BofA Commodity Index eXtra (MLCX). This methodology is designed to provide the foundation for liquid, consistent, representative and cost-efficient benchmarks for measuring commodity market performance. The futures contracts included in the Index are intended to be sufficiently liquid to accommodate the level of trading needed to support trading in the Index. The selection mechanism is therefore based primarily on liquidity. To determine liquidity, the notional value of traded contracts is derived from the total trading volume during the most recent twelve month period from July 1 through June 30, and the value of that trading volume. Eligible contracts are ranked on the basis of their liquidity. A preliminary set of contracts are selected for the index in ranked order, subject to the minimum and maximum requirements set for each market sector. The weight of each index contract is determined on the basis of its associated global production value, which is a measure that is designed to provide a non-biased reflection of the relative economic importance of each commodity contract in the global economy. Each market sector is adequately represented in the Index in relation to its share of the global market, adjusted to avoid excessive exposure to any one market sector. The evaluation of liquidity and global production value are evaluated annually, with selected contracts for the upcoming calendar year implemented at the December month end rebalancing.

Component Selection Criteria. The Index is based on the ICE BofA Commodity eXtra Index (“MLCX03”) and generally uses the same selection, weighting and calculation methodologies that apply to the MLCX family of indices, but with certain modifications. In particular, the modifications include a monthly rebalancing frequency, a different method for calculating “percentage target weights and a five-day contract roll schedule. In addition, contract production weights are recalculated monthly. On a monthly basis, the Index evaluates the current qualifying contracts selected for inclusion in MLCX03 and ranks

those contracts based on their degree of positive carry. The Index contract weights are then adjusted to increase the allocation to the top 10 high-carry commodities and reduce the allocation to the remaining low-carry commodities.

Investment Policies

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

Fundamental Investment Policies

The Fund may not:

Concentrate its investments in a particular industry, as that term is used in the Investment Company Act.

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

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

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

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

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

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

Notations Regarding the Fund's Fundamental Investment Policies

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

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

Non-Fundamental Investment Policies of the Fund

Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:

Portfolio Manager Compensation Overview

The discussion below describes the Portfolio Managers' compensation as of October 31, 2024.

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

As of October 31, 2024, the Portfolio Managers did not beneficially own shares of the Fund.

Administrator, Custodian and Transfer Agent.

not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

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

Pursuant to the current Securities Lending Agency Agreement:

payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients. These financial incentives may cause the Intermediary to recommend the Fund or other Products or otherwise promote the Fund or other Products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Fund or other Products.

Determination of Net Asset Value

derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

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

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

Brokerage Transactions

broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in the Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

There were no brokerage commissions paid on behalf of the Fund for the fiscal years ended October 31, 2024, October 31, 2023 and October 31, 2022.

The following table sets forth the names of the Fund's “regular broker dealers,” as defined under Rule 10b-1 of the 1940 Act, which derive more than 15% of their gross revenues from securities-related activities and in which the Fund invests, together with the market value of each investment as of the Fund’s fiscal year ended October 31, 2024:

Issuer	Market Value of Investment
Citigroup, Inc.	$500,129
Bank of America Corp.	309,431

Issuer	Market Value of Investment
Bank of Montreal	250,140

The Fund's purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BlackRock manages or advises. If purchases or sales of portfolio securities of the Fund and one or more other accounts managed or advised by BlackRock are considered at or about the same time, transactions in such securities are allocated among the Fund and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BlackRock may deal, trade and invest for its own account in the types of securities in which the Fund may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Creation and Redemption of Creation Units

Shares Per Creation Unit	Approximate Value Per Creation Unit (U.S.$)
50,000	$1,037,145.30

Fund Deposit. The consideration for purchase of Creation Units of the Fund is generally cash. However, in some cases the consideration consists of a designated portfolio of securities, assets or other positions (including any portion of such securities for which cash may be substituted) (“Deposit Securities” or “Creation Basket”) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which will be applicable (subject to possible amendment or correction) to creation requests received in proper form. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

The Fund’s current policy is to accept cash in substitution for the Deposit Securities it might otherwise accept as in-kind consideration for the purchase of Creation Units. The Fund may, at times, elect to receive Deposit Securities (i.e., the in-kind deposit of a designated portfolio of securities and other instruments) and a Cash Component as consideration for the purchase of Creation Units. If the Fund elects to accept Deposit Securities, a purchaser's delivery of the Deposit Securities together with the Cash Component will constitute the “Fund Deposit,” which will represent the consideration for a Creation Unit of the Fund. Please see the Cash Purchase Method section below and the following discussion summarizing the Deposit Security method for further information on purchasing Creation Units of the Fund.

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

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

allows such member or participant to place orders for the purchase and redemption of Creation Units is referred to as an “Authorized Participant.” All shares of the Fund, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant. Creation Units may be purchased only by or through a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the NAV of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

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

Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Authorized Participants who create shares on a day when one or more constituents of the Underlying Index is experiencing a market disruption event could bear additional costs associated with increased market risk. In the case of a creation received on a day when a market disruption event is ongoing, Authorized Participants will need to post additional collateral to receive shares; this collateral will be used to cover adverse price moves on the affected futures, with the residual, if any, returned upon resolution of the market disruption event.

Costs Associated with Creation Transactions.

The following table sets forth the Fund's standard creation transaction fees and maximum additional charge (as described above):

Standard Creation Transaction Fee	Maximum Additional Charge*
$225	7.0 %

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

The Fund generally redeems Creation Units solely for cash. However, the Fund reserves the right to distribute securities and other instruments in-kind as payment for Creation Units being redeemed. Please see the Cash Redemption Method section below and the following discussion summarizing the in-kind method for further information on redeeming Creation Units of the Fund.

on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

If redemptions are not paid in cash, the redemption proceeds for a Creation Unit generally consist of Fund Securities and other instruments, plus the Cash Amount, which is an amount equal to the difference between the NAV of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities and other instruments, less a redemption transaction fee (as described below).

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

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

Costs Associated with Redemption Transactions.

The following table sets forth the Fund's standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption Transaction Fee	Maximum Additional Charge*
$225	2.0 %

As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

Authorized Participants who redeem shares on a day when one or more constituents of the Underlying Index is experiencing a market disruption event could bear additional costs associated with increased market risk. In the case of a redemption received on a day when a market disruption event is ongoing, Authorized Participants will receive monetary proceeds, subject to applicable law, once the execution price has been finalized, either because the market disruption event has resolved or because the counterparty has closed out the position (whichever is earlier).

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

Taxes

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

As of October 31, 2024, the tax year-end of the Fund, the Fund had non-expiring capital loss carryforwards in the amount of $1,832 available to offset future realized capital gains.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

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

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

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