U.S. BOND MARKET OVERVIEW

The U.S. bond market posted a modestly positive gain for the 12 months ended October 31, 2017 (“reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned 0.90%.

Improving economic growth and rising interest rates contributed to the U.S. bond market performance. The U.S. economy expanded by 2.3% for the 12 months ended September 2017 (the most recent data available), its fastest year-over-year growth rate in two years. The job market mirrored this progress, with the unemployment rate declining to its lowest level in more than 16 years. The healthier economy and job market contributed to consumer confidence reaching its highest level since January 2004, while retail sales increased by 4.6% for the reporting period.

On the manufacturing side, industrial output increased by 0.90% for the reporting period, reflecting a recovery in 2017 after industrial production contracted for much of 2016. At the same time, inflation was modest, with the consumer price index rising by 2.2% for the 12 months ended September 2017, well below the long-term historical average of 3.3%.

In that environment, the U.S. Federal Reserve Bank (“Fed”) worked to normalize monetary policy by beginning to reverse some of the measures taken in response to the 2008 financial crisis. The Fed increased interest rates by a quarter percentage point three times during the reporting period, from 0.5% to 1.25%, which contributed to higher short-term bond yields. The Fed also started reducing the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017.

Another catalyst for rising bond yields was the outcome of the U.S. presidential election in November 2016. The new administration was expected to enact pro-growth fiscal policies, including lower taxes and significant infrastructure spending, which was expected to lead to a higher federal budget deficit. Expectations of an increase in the supply of U.S. Treasury bonds, based on the government’s need to fill the larger budget gap, led to an increase in U.S. bond yields during the reporting period.

Overall, short-term U.S. Treasury bond yields rose more than long-term bond yields. For example, the yield of the two-year U.S. Treasury note increased from 0.86% to 1.6% over the course of the reporting period, while the yield of the 30-year U.S. Treasury bond rose less than half that amount, increasing from 2.58% to 2.88%. The yield difference, or spread, between short-term and longer-term U.S. Treasury securities reached levels not seen since before the 2008 financial crisis, when the Fed was raising short-term interest rates aggressively.

Interest rate trends had important implications for returns across the U.S. bond market. U.S. Treasury bonds declined for the reporting period and were the weakest performers among the broad market segments.

In contrast, economically sensitive corporate bonds performed well, benefiting from improving economic growth, healthy corporate profits, strong investor demand for their comparatively higher yields, and expectations of the new administration’s corporate-friendly policies. As a result, the yield spread between U.S. Treasury securities and corporate bonds — both investment-grade and high-yield — declined for the reporting period.

Mortgage-backed securities, which have higher yields than U.S. Treasury securities but greater sensitivity to interest rate changes than corporate bonds, finished between these two sectors, managing modest gains for the reporting period.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® SHORT MATURITY BOND ETF

The iShares Short Maturity Bond ETF (the “Fund”) seeks to maximize current income 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 and maintain a weighted average maturity that is less than three years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 1.57%, net of fees.

The Fed raised interest rates three times during the reporting period. The moves by the Fed and investors’ outlook for additional interest rate increases drove short-term yields higher, generally limiting returns of short-term bonds.

Despite the rise in interest rates, the Fund performed well relative to the Bloomberg Barclays Short-Term Government/Corporate Index for the reporting period. The decision to overweight corporate bonds was an important driver of performance relative to the broader short-term bond market, as corporate bonds outperformed Treasuries for the reporting period. Corporate debt benefitted from the strengthening economic environment, solid corporate earnings growth, and a diminishing risk of default. Within corporate bonds, the Fund’s largest holdings were in the financials sector, which could benefit from tax reform and deregulation. Bank bonds were particular areas of strength, reflecting the fact that stronger economic growth and higher interest rates directly benefit their business.

The Fund’s performance was also helped by a relative overweight towards securitized products. In particular, the Fund was overweight in asset-backed securities and commercial mortgage-backed securities, both of which performed well for the reporting period. Demand from investors seeking higher yields helped support securitized bond prices.

To minimize the negative impact of the Fed’s interest rate increases, the Fund maintained similar or slightly short interest rate sensitivity (that is, less price sensitivity to interest rate changes) relative to the broader short-term bond market for most of the reporting period. By the end of the reporting period, the Fund shifted to a slightly longer interest rate sensitivity relative to the broader market in anticipation of continued low bond market volatility.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® SHORT MATURITY MUNICIPAL BOND ETF

The iShares Short Maturity Municipal Bond ETF (the “Fund”) seeks to maximize tax-free current income 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. Under normal circumstances, the effective duration of the Fund’s portfolio is expected to be 1.2 years or less, as calculated by the management team, and is not expected to exceed 1.5 years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 0.93%, net of fees.

The Fed raised interest rates three times during the reporting period. The moves by the Fed and investors’ outlook for additional interest rate increases drove short-term yields higher, limiting returns of short-term bonds.

Within the municipal bond market, the effect of these interest rate increases was offset to some degree by intense demand from foreign investors seeking yield, as global interest rates remained low. Even as demand increased, supply was constrained by reduced municipal bond issuance, particularly among shorter maturities. Due to strong demand and limited supply, municipal yields declined relative to those available on fully taxable securities.

The Fund performed generally in line with the Bloomberg Barclays Municipal Bond: 1 Year (1-2) Index for the reporting period. The leading detractor from the Fund’s performance relative to the broader market was an underweight position in bonds maturing in one to two years, as these securities performed well during the reporting period. The Fund was also underweight in highly-rated, pre-refunded securities, which detracted from the Fund’s performance relative to the broader market.

On the upside, the Fund benefited from overweight positions in the tax-backed local, school district, health, education, and corporate sectors. Un-rated bonds, which had underlying equivalent ratings of AA and A and made up nearly 30% of Fund assets on average for the reporting period, were the leading contributors to relative performance. Bonds rated BBB were another source of strength relative to the broader market.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® ULTRA SHORT-TERM BOND ETF

The iShares Ultra Short-Term Bond ETF (the “Fund”) seeks to provide current income consistent with preservation of capital 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 and maintain a dollar-weighted average maturity that is less than 180 days. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 1.47%, net of fees.

The Fed raised interest rates three times during the reporting period. The moves by the Fed and investors’ outlook for additional interest rate increases drove short-term yields higher, generally limiting returns of short-term bonds.

In that environment, the Fund performed well relative to the Bank of America Merrill Lynch 6-Month U.S. Treasury Bill Index for the reporting period. The decision to overweight corporate bonds was an important driver of the Fund’s performance relative to the broader market, as corporate bonds outperformed Treasuries for the reporting period. Corporate debt benefited from the strengthening economic environment, solid corporate earnings growth, and a diminishing risk of default. Within the corporate sector, bank debt contributed the most to the Fund’s return, followed by debt issued by auto manufacturers.

An increased position in floating-rate securities (“floaters”) also contributed to the Fund’s return for the reporting period, as floating-rate debt saw its yield rise along with interest rates. The allocation to floaters increased to approximately 53% by the end of the reporting period, and was a significant driver of relative performance.

This allocation to floaters also had the effect of limiting the Fund’s interest rate sensitivity, or stock price sensitivity to interest rate changes, which is desirable when interest rates rise. The Fund further managed its exposure to rising interest rates by adding securities with three- to six-month maturities and variable-rate securities with somewhat longer maturities. As interest rates rise, yields on floaters adjust higher, while those very short-term securities mature and the proceeds can be reinvested at the new, higher rate.

MANAGEMENT’S DISCUSSIONSOF FUND PERFORMANCE 11

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in a Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Financial Statements

iSHARES^® U.S. ETF TRUST

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

iShares ETF	Diversification Classification
Short Maturity Bond	Non-diversified
Short Maturity Municipal Bond	Diversified
Ultra Short-Term Bond	Diversified

Pursuant to the Trust’s organizational documents, the Funds’ officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

Each Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Funds. The investments of each Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

NOTESTO FINANCIAL STATEMENTS 45

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

• Forward currency contracts are valued based on that day’s prevailing forward exchange rate for the underlying currencies. Interpolated forward exchange rates are used for contracts with interim settlement dates for which quotations are not available.

• Repurchase agreements are valued at amortized cost, which approximates market value.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for each Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing

transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, and payment-in-kind interest income, are recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements. In a repurchase agreement, a Fund purchases a security from a counterparty who agrees to repurchase the same security at a mutually agreed upon date and price. On a daily basis, the counterparty is required to maintain collateral subject to the agreement and in value no less than the agreed repurchase amount. The agreements are conditioned upon the collateral being deposited under the Federal Reserve book entry system or held in a segregated account by the Fund’s custodian or designated sub-custodians under tri-party repurchase agreements. In the event the counterparty defaults and the fair value of the collateral declines, the Fund could experience losses, delays and costs in liquidating the collateral.

Repurchase agreements are entered into by the Funds under Master Repurchase Agreements (each, an “MRA”). The MRA permits the Funds, under certain circumstances including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables with collateral held by and/or posted to the counterparty. As a result, one single net payment is created. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Based on the terms of the MRA, the Fund receives securities as collateral with a market value in excess of the repurchase price at maturity. Upon a bankruptcy or insolvency of the MRA counterparty, the Fund would recognize a liability with respect to such excess collateral. The liability reflects the Fund’s obligation under bankruptcy law to return the excess to the counterparty.

The following table summarizes the Fund’s open repurchase agreements as of October 31, 2017 which are subject to offset under an MRA:

iShares ETF	Market Value of Repurchase Agreements		Non-cash Collateral Received a		Net Amount
Short Maturity Bond	$	30,000,000	$	30,000,000	$	—
Ultra Short-Term Bond		5,750,000		5,750,000		—

^a  Collateral received in excess of the market value of repurchase agreements is not presented in this table. The total collateral received by each Fund is disclosed in each Fund’s schedule of investments.

FOREIGN CURRENCY TRANSLATION

The accounting records of the Funds are maintained in U.S. dollars. Foreign currencies, as well as investment securities and other assets and liabilities denominated in foreign currencies, are translated into U.S. dollars using exchange rates deemed appropriate by the investment adviser. Purchases and sales of securities, income receipts and expense payments are translated into U.S. dollars on the respective dates of such transactions.

NOTESTO FINANCIAL STATEMENTS 47

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

Each Fund does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of securities. Such fluctuations are reflected by the Funds as a component of realized and unrealized gains and losses from investments for financial reporting purposes. Each Fund reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.

FOREIGN TAXES

The Funds may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Funds invest. These foreign taxes, if any, are paid by the Funds and are reflected in their statements of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of October 31, 2017, if any, are disclosed in the Funds’ statements of assets and liabilities.

DISTRIBUTIONS TO SHAREHOLDERS

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

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedules of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for each Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the statements of assets and liabilities. Income earned by the Funds from securities lending is disclosed in the statements of operations.

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

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

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2017:

iShares ETF and Counterparty	Market Value of Securities on Loan		Cash Collateral Received  a		Net Amount
Short Maturity Bond

RECENT ACCOUNTING STANDARD

In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on Purchase Callable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchased callable debt securities that have explicit, non-contingent call features and are callable at fixed prices will be amortized to the earliest call date. The guidance will be applied on a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management is currently evaluating the impact of this guidance to the Funds.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

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

iShares ETF	Investment Advisory Fee
Short Maturity Bond		0.25	%
Short Maturity Municipal Bond		0.25
Ultra Short-Term Bond		0.08

Prior to December 16, 2016, for its investment advisory services to the iShares Ultra Short-Term Bond ETF, BFA was entitled to an annual investment advisory fee of 0.18% based on the average daily net assets of the Fund.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, each Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, each Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the total of securities lending agent services and collateral investment fees paid were as follows:

iShares ETF	Fees Paid to BTC
Short Maturity Bond	$	37,965

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

Cross trading is the buying or selling of portfolio securities between funds to which BFA (or an affiliate) serves as investment adviser. At its regularly scheduled quarterly meetings, the Board reviews such transactions as of the most recent calendar quarter for compliance with the requirements and restrictions set forth by Rule 17a-7.

For the year ended October 31, 2017, the purchase and sales transactions executed by the iShares Short Maturity Bond ETF pursuant to Rule 17a-7 under the 1940 Act were $5,158,009 and $ —, respectively.

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statements of operations.

It is possible that, from time to time, BlackRock and/or funds managed by BFA or an affiliate (collectively, “Affiliates”) may purchase and hold shares of a Fund. Affiliates reserve the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an authorized participant at any time some or all of the shares of a Fund acquired for their own accounts. A large sale or redemption of shares of a Fund by Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund. As of October 31, 2017, the number of affiliated accounts that individually represent more than 10% ownership of a Fund’s total shares outstanding and the aggregate percentage of net assets represented by such holdings were as follows:

iShares ETF	Number of Affiliated Accounts		Aggregate Affiliated Ownership Percentage
Ultra Short-Term Bond		1		23	%

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Funds for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BTC and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017 were as follows:

	U.S. Government Obligations				Other Securities
iShares ETF	Purchases		Sales		Purchases		Sales
Short Maturity Bond	$	18,368,962	$	28,892,679	$	2,202,192,432	$	1,090,362,703
Short Maturity Municipal Bond		—		—		77,844,038		56,767,280
Ultra Short-Term Bond		1,161,019		1,883,451		63,398,345		1,903,405

There were no in-kind transactions (see Note 4) for the year ended October 31, 2017.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of each Fund are not redeemable. Transactions in capital shares for each Fund are disclosed in detail in the statements of changes in net assets.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units

NOTESTO FINANCIAL STATEMENTS 51

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” in the statements of changes in net assets.

5. FORWARD CURRENCY CONTRACTS

The iShares Short Maturity Bond ETF uses forward currency contracts to hedge the currency exposure of non-U.S. dollar-denominated securities held in its portfolio. A forward currency contract is an obligation to purchase or sell a currency against another currency at a specified future date at an agreed upon price and quantity. Forward currency contracts are traded over-the-counter (“OTC”) and not on an organized exchange.

The contract is marked-to-market daily and the change in market value is recorded as unrealized appreciation or depreciation. When the contract is closed, a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed is recorded. Non-deliverable forward currency contracts (“NDFs”) are settled with the counterparty in cash without the delivery of foreign currency. Losses may arise if there are unfavorable movements in the value of a foreign currency relative to the U.S. dollar or if the counterparties do not meet the terms of the agreement. A fund’s use of forward currency contracts also involves the risks of imperfect correlation between the value of its currency positions and its other investments or the fund failing to close out its position due to an illiquid market.

As of October 31, 2017, the iShares Short Maturity Bond ETF held no open forward currency contracts.

The following table shows the realized and unrealized gains (losses) on forward currency contracts held by the iShares Short Maturity Bond ETF during the year ended October 31, 2017 and the related locations in the statements of operations, presented by risk exposure category:

	Net Realized Gain (Loss)		Net Change in Unrealized Appreciation/Depreciation
Forward currency contracts	$	8,261,812	$	(3,569,633	)

For the year ended October 31, 2017, the average quarter-end amounts purchased and sold in U.S. dollars for the iShares Short Maturity Bond ETF were $5,624,923 and $67,508,879, respectively.

The Fund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund. In order to better define its contractual rights and to secure rights that will help the Fund to mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. master agreement (“ISDA Master Agreement”) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs OTC derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency.

The collateral requirements under an ISDA Master Agreement are typically calculated by netting the mark-to-market amount for each transaction under such agreement, and comparing that amount to the value of any collateral currently pledged by the

52 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

parties. Except for NDFs, the forward currency contracts held by the Fund generally do not require collateral. Cash collateral pledged to the counterparty, if any, is presented as “Cash pledged to broker for forward currency contracts” on the statement of assets and liabilities. Cash received as collateral from the counterparty may be reinvested in money market funds, including those managed by the Fund’s investment adviser, or its affiliates. Such collateral, if any, is presented in the statement of assets and liabilities as “Investments in securities – affiliated” and “Payable due to broker for collateral on forwards.” To the extent amounts due to the Fund from the counterparty are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty non-performance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

For financial reporting purposes, the Fund does not offset financial assets and financial liabilities that are subject to netting arrangements in the statements of assets and liabilities.

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit

NOTESTO FINANCIAL STATEMENTS 53

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer’s ability to make payments of principal and/or interest or otherwise affect the value of such securities. Municipal securities can be significantly affected by political or economic changes as well as uncertainties in the municipal market related to, government regulation, taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues from the project or the assets.

7. INCOME TAX INFORMATION

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of each Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to distributions received from a regulated investment company, the treatment of straddles and foreign currency transactions, were reclassified to the following accounts:

iShares ETF	Paid-in Capital		Undistributed Net Investment Income/Distributions in Excess of Net Investment Income			Undistributed Net Realized Gain/Accumulated Net Realized Loss
Short Maturity Bond	$	1	$	(216,525	)	$	216,524
Ultra Short-Term Bond		—		2			(2	)

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

iShares ETF	2017		2016
Short Maturity Bond
Ordinary income	$	34,147,741	$	21,492,109
Short Maturity Municipal Bond
Tax-exempt income	$	359,506	$	245,046

iSHARES^® U.S. ETF TRUST

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

iShares ETF	Undistributed Ordinary Income		Undistributed Tax-Exempt Income		Capital Loss Carryforwards			Net Unrealized Gains  (Losses) a			Total
Short Maturity Bond	$	2,799,301	$	—	$	—		$	3,856,167		$	6,655,468

Ultra Short-Term Bond		138,705		—		(20,828	)		103,278			221,155

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

As of October 31, 2017, the Funds had non-expiring capital loss carryforwards available to offset future realized capital gains as follows:

iShares ETF	Non- Expiring
Short Maturity Municipal Bond	$	38,713
Ultra Short-Term Bond		20,828

For the year ended October 31, 2017, the iShares Short Maturity Bond ETF utilized $818,332 of its capital loss carryforwards.

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

Contract

iSHARES^® U.S. ETF TRUST

I. iShares Short Maturity Bond ETF and iShares Short Maturity Municipal Bond ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Funds. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Funds, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Funds, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Funds — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of each Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising such Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the applicable Peer Groups. The Board further noted that due to the limitations in providing comparable funds in the various Peer Groups, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Funds in all instances.

The Board also noted that the investment advisory fee rates and overall expenses (net of waivers and reimbursements) for the Funds were lower than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in their respective Peer Group, excluding iShares funds.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as any particular Fund, Broadridge also provided, and the Board reviewed, a comparison of such Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

Board Review and Approval of Investment Advisory

Contract (Continued)

iSHARES^® U.S. ETF TRUST

The Board noted that each Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for each Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on each Fund’s short- and longer-term performance in comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that each Fund generally performed in line with expectations relative to each Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Funds. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Funds, as well as the resources available to them in managing the Funds. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that each Fund had met its investment objective consistently since its respective inception date.

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

Costs of Services Provided to Funds and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Funds to BlackRock, on a Fund-by-Fund basis and in the aggregate, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Funds’ operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Funds. The Board also discussed BFA’s profit margin as reflected in the Funds’ profitability analyses and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Funds and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Funds’ assets, noting that the issue of economies of scale had been focused on by the

Contract (Continued)

iSHARES^® U.S. ETF TRUST

15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Funds did not provide for any breakpoints in the Funds’ investment advisory fee rates as the assets of the Funds increase. However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Funds may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Contract at least annually, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do manage Other Accounts with similar investment strategies or investment mandates as the Funds. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Funds, including in terms of the different and generally more extensive services provided to the Funds, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Funds, as publicly traded ETFs, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Funds’ advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rates under the Advisory Contract for the Funds were generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Funds by BFA, such as payment of revenue to BTC, the Funds’ securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Funds in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for

portfolio transactions for the Funds. The Board further noted that any portfolio transactions on behalf of the Funds placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Funds’ shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Conclusion — Based on the considerations described above, the Board determined that each Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Contract for the coming year.

II. iShares Ultra Short-Term Bond ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

Board Review and Approval of Investment Advisory

Contract (Continued)

iSHARES^® U.S. ETF TRUST

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

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in comparison with its selected competitors and benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s strategy, selected competitors and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

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

Costs of Services Provided to Fund and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Fund to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology

and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on by the 15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders.

However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

U.S. BOND MARKET OVERVIEW

The U.S. bond market posted a modestly positive gain for the 12 months ended October 31, 2017 (“reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned 0.90%.

Improving economic growth and rising interest rates contributed to the U.S. bond market performance. The U.S. economy expanded by 2.3% for the 12 months ended September 2017 (the most recent data available), its fastest year-over-year growth rate in two years. The job market mirrored this progress, with the unemployment rate declining to its lowest level in more than 16 years. The healthier economy and job market contributed to consumer confidence reaching its highest level since January 2004, while retail sales increased by 4.6% for the reporting period.

On the manufacturing side, industrial output increased by 0.90% for the reporting period, reflecting a recovery in 2017 after industrial production contracted for much of 2016. At the same time, inflation was modest, with the consumer price index rising by 2.2% for the 12 months ended September 2017, well below the long-term historical average of 3.3%.

In that environment, the U.S. Federal Reserve Bank (“Fed”) worked to normalize monetary policy by beginning to reverse some of the measures taken in response to the 2008 financial crisis. The Fed increased interest rates by a quarter percentage point three times during the reporting period, from 0.5% to 1.25%, which contributed to higher short-term bond yields. The Fed also started reducing the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017.

Another catalyst for rising bond yields was the outcome of the U.S. presidential election in November 2016. The new administration was expected to enact pro-growth fiscal policies, including lower taxes and significant infrastructure spending, which was expected to lead to a higher federal budget deficit. Expectations of an increase in the supply of U.S. Treasury bonds, based on the government’s need to fill the larger budget gap, led to an increase in U.S. bond yields during the reporting period.

Overall, short-term U.S. Treasury bond yields rose more than long-term bond yields. For example, the yield of the two-year U.S. Treasury note increased from 0.86% to 1.6% over the course of the reporting period, while the yield of the 30-year U.S. Treasury bond rose less than half that amount, increasing from 2.58% to 2.88%. The yield difference, or spread, between short-term and longer-term U.S. Treasury securities reached levels not seen since before the 2008 financial crisis, when the Fed was raising short-term interest rates aggressively.

Interest rate trends had important implications for returns across the U.S. bond market. U.S. Treasury bonds declined for the reporting period and were the weakest performers among the broad market segments.

In contrast, economically sensitive corporate bonds performed well, benefiting from improving economic growth, healthy corporate profits, strong investor demand for their comparatively higher yields, and expectations of the new administration’s corporate-friendly policies. As a result, the yield spread between U.S. Treasury securities and corporate bonds — both investment-grade and high-yield — declined for the reporting period.

Mortgage-backed securities, which have higher yields than U.S. Treasury securities but greater sensitivity to interest rate changes than corporate bonds, finished between these two sectors, managing modest gains for the reporting period.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® INTEREST RATE HEDGED HIGH YIELD BOND ETF

The iShares Interest Rate Hedged High Yield Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares iBoxx $ High Yield Corporate Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 10.26%, net of fees.

Despite an environment of rising interest rates and increasing yields, high-yield corporate bonds performed well during the reporting period, as investors continued to seek yield. The market for high-yield corporate bonds benefited from steady economic growth, strong earnings, and lower default risk. Decreasing default risk has driven the high-yield spread (the difference in yield between high-yield bonds and relatively safe Treasury bonds) to the lowest level since 2014.

From a sector perspective, the majority of the Fund’s return came from the industrial sector, which comprised approximately 88% of the Fund on average for the reporting period. Within the industrial sector, the largest contributor to the Fund’s return was debt from communications companies, in particular the cable and satellite and wireless industries. Bonds issued by energy companies also performed well, as oil prices stabilized in the $45–55 price range, which was sufficient for oil companies to remain solvent. Debt issued by companies in the consumer non cyclicals, most notably the healthcare industry, and consumer cyclicals industries also made significant contributions to the Fund’s return.

In terms of credit, higher-rated credit (B and Ba-rated) provided the majority of the contribution to the Fund’s performance for the reporting period, but lower-rated credit (Caa-rated) also provided a significant contribution, despite representing only 13% of the Fund on average.

Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling rates usually tend to increase bond prices. An interest rate hedged fund attempts to mitigate these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

Rising interest rates during the reporting period meant that hedging activity contributed to the Fund’s return. The Fund’s interest rate hedge seeks near-zero interest rate sensitivity and was successful within its targeted range. As a result, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund’s return fluctuated based on direct exposure to the yield premium of high-yield corporate bonds, independent of rising interest rates during the reporting period.

iSHARES^® INTEREST RATE HEDGED CORPORATE BOND ETF

The iShares Interest Rate Hedged Corporate Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares iBoxx $ Investment Grade Corporate Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 7.11%, net of fees.

The market for corporate bonds benefited from economic growth, strong earnings, and lower default risk during the reporting period. Anticipated U.S. corporate tax cuts improved investor confidence in the future ability of corporations to pay their debts, strengthening demand for corporate bonds. The combination of stronger growth, policy proposals, and continued investor demand for yield created favorable conditions for the corporate bond market.

From a sector perspective, the majority of the Fund’s return came from the industrial sector, which comprised approximately 64% of the Fund on average for the reporting period. Within the industrial sector, the largest contributor to the Fund’s return was debt from energy companies, which performed well as oil prices stabilized in the $45-55 price range, which was sufficient for most oil companies to remain solvent. Bonds issued by pharmaceutical and technology companies also made significant contributions to the Fund’s performance, as did debt issued by the communications industry.

The financials sector also contributed to the Fund’s return for the reporting period. Among bonds issued by companies in the financials sector, debt issued by the banks industry was the most significant contributor. Increasing capital levels and reduced risk have made bank bonds more attractive for investors, sending the spread for U.S. banking bonds (the amount of yield investors require above Treasuries) to the lowest level since the financial crisis.

Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling rates usually tend to increase bond prices. An interest rate hedged fund attempts to mitigate these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

MANAGEMENT’S DISCUSSIONSOF FUND PERFORMANCE 9

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in a Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Financial Statements

iSHARES^® U.S. ETF TRUST

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

iShares ETF	Diversification Classification
Interest Rate Hedged High Yield Bond	Diversified
Interest Rate Hedged Coporate Bond	Diversified

Currently each Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an exchange-traded fund of iShares Trust (an “underlying fund”), an affiliate of the Funds. The financial statements and schedules of investments for the underlying funds can be found elsewhere in this report and should be read in conjunction with the Funds’ financial statements.

Pursuant to the Trust’s organizational documents, the Funds’ officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

Each Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Funds. The investments of each Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Exchange-traded funds and closed-end funds traded on a recognized securities exchange are valued at that day’s last reported trade price or the official closing price, as applicable, on the exchange where the fund is primarily traded. Funds traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

• Swap agreements are valued utilizing quotes received daily by independent pricing services or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for each Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions from the underlying funds, if any, are recognized on the ex-dividend date. Interest income is accrued daily.

DISTRIBUTIONS TO SHAREHOLDERS

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

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedules of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for each Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the statements of assets and liabilities. Income earned by the Funds from securities lending is disclosed in the statements of operations.

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

Securities lending transactions are entered into by the Funds under Master Securities Lending Agreements (“MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, a Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than that of the market value of the securities loaned, leaving the lender with a net amount

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and a Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2017:

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the iShares Interest Rate Hedged High Yield Bond ETF, BFA is entitled to an annual investment advisory fee of 0.65%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). The total of the investment advisory fee and acquired fund fees and expenses is the Fund’s total annual operating expenses. BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG”), after taking into account any fee waivers by HYG, plus 0.05%.

For its investment advisory services to the iShares Interest Rate Hedged Corporate Bond ETF, BFA is entitled to an annual investment advisory fee of 0.30%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur acquired fund fees and expenses. BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD”), after taking into account any fee waivers by LQD, plus 0.10%.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, each Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, each Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the total of securities lending agent services and collateral investment fees paid were as follows:

iShares ETF	Fees Paid to BTC
Interest Rate Hedged High Yield Bond	$	211,845
Interest Rate Hedged Corporate Bond		9,859

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

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statements of operations.

It is possible that, from time to time, BlackRock and/or funds managed by BFA or an affiliate (collectively, “Affiliates”) may purchase and hold shares of a Fund. Affiliates reserve the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an authorized participant at any time some or all of the shares of a Fund acquired for their own accounts. A large sale or redemption of shares of a Fund by Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund. As of October 31, 2017, the number of affiliated accounts that individually represent more than 10% ownership of a Fund’s total shares outstanding and the aggregate percentage of net assets represented by such holdings were as follows:

iShares ETF	Number of Affiliated Accounts		Aggregate Affiliated Ownership Percentage

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017 were as follows:

iShares ETF	Purchases		Sales

iShares ETF	In-kind Purchases		In-kind Sales
Interest Rate Hedged High Yield Bond	$	225,864,638	$	129,114,761
Interest Rate Hedged Corporate Bond		39,945,396		—

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of each Fund are not redeemable. Transactions in capital shares for each Fund are disclosed in detail in the statements of changes in net assets.

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

5. INTEREST RATE SWAPS

Interest rate swaps are used by each Fund to mitigate the potential impact of interest rates on the performance of the bonds held by the Fund or its underlying fund. Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. Interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Swap agreements are privately negotiated in the over-the-counter market. Each Fund enters into centrally cleared interest rate swaps.

NOTESTO FINANCIAL STATEMENTS 25

Notes to Financial Statements (Continued)

iSHARES^® U.S. ETF TRUST

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Funds’ counterparty on the swap. Each Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, each Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the schedules of investments and cash deposited is recorded on the statements of assets and liabilities as cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the statements of assets and liabilities. Payments received from (paid to) the CCP, including at termination, are recorded as realized gain (loss) in the statements of operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the statements of assets and liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring

NOTESTO FINANCIAL STATEMENTS 27

iSHARES^® U.S. ETF TRUST

the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

7. INCOME TAX INFORMATION

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of each Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to the accounting for swap agreements, distributions paid in excess of taxable income and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

iShares ETF	Paid-in Capital			Undistributed Net Investment Income/Distributions in Excess of  Net Investment Income			Undistributed Net Realized Gain/Accumulated Net Realized  Loss
Interest Rate Hedged High Yield Bond	$	2,524,910		$	(907,545	)	$	(1,617,365	)
Interest Rate Hedged Corporate Bond		(26,410	)		(320,977	)		347,387

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

iShares ETF	2017		2016
Interest Rate Hedged High Yield Bond
Ordinary income	$	8,196,203	$	1,756,097
Interest Rate Hedged Corporate Bond
Ordinary income	$	1,459,798	$	731,888

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

iShares ETF	Capital Loss Carryforwards			Net Unrealized Gains  (Losses) a		Total
Interest Rate Hedged High Yield Bond	$	(1,500,936	)	$	932,252	$	(568,684	)
Interest Rate Hedged Corporate Bond		(2,498,799	)		3,820,229		1,321,430

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Interest Rate Hedged High Yield Bond ETF and iShares Interest Rate Hedged Corporate Bond ETF (constituting funds of the iShares U.S. ETF Trust, hereafter referred to as the “Funds”) as of October 31, 2017, and the results of each of their operations, the changes in each of their net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Board Review and Approval of Investment Advisory Contract

iSHARES^® U.S. ETF TRUST

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Funds. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Funds, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Funds, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Funds — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of each Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising such Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the applicable Peer Groups. The Board further noted that due to the limitations in providing comparable funds in the various Peer Groups, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Funds in all instances.

The Board also noted that the investment advisory fee rates and overall expenses (net of waivers and reimbursements) for the Funds were higher than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in their respective Peer Group, excluding iShares funds. The Board further noted that each Fund’s pricing reflects the use of interest rate hedging strategies, as compared to several of the funds in the Peer Group, which are not interest rate hedged. The Board noted that the Peer Group for the iShares Interest Rate Hedged Corporate Bond ETF contained only three comparison funds identified by Broadridge, excluding iShares funds.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as any particular Fund, Broadridge also provided, and the Board reviewed, a comparison of such Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

The Board noted that each Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for each Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on each Fund’s short- and longer-term performance in comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that each Fund generally performed in line with expectations relative to each Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Funds. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Funds, as well as the resources available to them in managing the Funds. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that each Fund had met its investment objective consistently since its respective inception date.

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

Costs of Services Provided to Funds and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Funds to BlackRock, on a Fund-by-Fund basis and in the aggregate, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Funds’ operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Funds. The Board also discussed BFA’s profit margin as reflected in the Funds’ profitability analyses and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Funds and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Funds’ assets, noting that the issue of economies of scale had been focused on by the 15(c)

BOARD REVIEWAND APPROVALOF INVESTMENT ADVISORY CONTRACT 33

Board Review and Approval of Investment Advisory Contract (Continued)

iSHARES^® U.S. ETF TRUST

Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Funds did not provide for any breakpoints in the Funds’ investment advisory fee rates as the assets of the Funds increase. However, the Board noted that to the extent that a Fund invests in an underlying iShares fund that has breakpoints, the shareholders of that Fund would benefit from breakpoints in such underlying iShares fund’s respective investment advisory fee rate as the assets of such underlying iShares fund, on an aggregated basis with the assets of certain other iShares funds, increase. The Board further noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Funds may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Contract at least annually, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with similar investment strategies or investment mandates as the Funds. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Funds, including in terms of the different and generally more extensive services provided to the Funds, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Funds, as publicly traded ETFs, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Funds’ advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rates under the Advisory Contract for the Funds were generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Funds by BFA, such as payment of revenue to BTC, the Funds’ securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Funds in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an

Board Review and Approval of Investment Advisory Contract (Continued)

iSHARES^® U.S. ETF TRUST

agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Funds. The Board further noted that any portfolio transactions on behalf of the Funds placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Funds’ shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Conclusion — Based on the considerations described above, the Board determined that each Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Contract for the coming year.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

Notes to Financial Statements

iSHARES^® TRUST

iShares Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated December 16, 1999.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

iShares ETF	Diversification Classification
iBoxx $ High Yield Corporate Bond	Diversified
iBoxx $ Investment Grade Corporate Bond	Diversified

The investment objective of each Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of its underlying index. The investment adviser uses a “passive” or index approach to try to achieve each Fund’s investment objective.

Pursuant to the Trust’s organizational documents, the Funds’ officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

Each Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Funds. The investments of each Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration factors that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such factors are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

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

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for each Fund’s investments is included in its schedule of investments.

NOTESTO FINANCIAL STATEMENTS 189

Notes to Financial Statements (Continued)

iSHARES^® TRUST

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

DISTRIBUTIONS TO SHAREHOLDERS

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

LOANS OF PORTFOLIO SECURITIES

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

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Funds may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates. As of February 28, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedules of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for each Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of February 28, 2017 and the total value of the related cash collateral are disclosed in the statements of assets and liabilities. Income earned by the Funds from securities lending is disclosed in the statements of operations.

iSHARES^® TRUST

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Funds benefit from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. Each Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

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

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of February 28, 2017:

RECENT ACCOUNTING STANDARD

In March 2017, the Financial Accounting Standards Board issued an update to amend the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for premiums to the earliest call date, but do not require an accounting change for securities held at a discount. The amendments are effective for financial statements for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Management is evaluating the impact, if any, of this guidance on the Funds’ financial statements and disclosures.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the iShares iBoxx $ High Yield Corporate Bond ETF, BFA is entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Investment Advisory Fee			Aggregate Average Daily Net Assets

	0.4287	a	Over $47 billionb

^a  Investment advisory fee level reflects a 5% reduction (rounded to the fourth decimal place) from the investment advisory fee at the prior aggregate average daily net asset level.

^b  Breakpoint level was amended effective July 1, 2016.

For its investment advisory services to the iShares iBoxx $ Investment Grade Corporate Bond ETF, BFA is entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Investment Advisory Fee			Aggregate Average Daily Net Assets

	0.1222	a	Over $281 billion

^a  Investment advisory fee level reflects a 5% reduction (rounded to the fourth decimal place) from the investment advisory fee at the prior aggregate average daily net asset level.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, each Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, each Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of each Fund are not redeemable. Transactions in capital shares for each Fund are disclosed in detail in the statements of changes in net assets.

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

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind contributions are reflected as “Due from custodian” and securities related to in-kind redemptions are reflected as “Securities related to in-kind transactions” in the statements of assets and liabilities.

5. PRINCIPAL RISKS

In the normal course of business, each Fund’s investment activities expose it to various types of risk associated with the financial instruments and markets in which it invests. The significant types of financial risks each Fund is exposed to include market risk and credit risk. Each Fund’s prospectus provides details of these and other types of risk.

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Mortgage-backed securities and securities with longer durations tend to be more sensitive to interest rate

NOTESTO FINANCIAL STATEMENTS 195

Notes to Financial Statements (Continued)

iSHARES^® TRUST

changes, usually making them more volatile than other types of bonds or securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

High yield securities that are rated below investment-grade (including those bonds rated lower than “BBB-” by Standard & Poor’s Ratings Services and Fitch or “Baa3” by Moody’s) or are unrated, may be more volatile than higher-rated securities of similar maturity. High yield securities may also be subject to greater levels of credit or default risk than higher-rated securities and high yield securities may be less liquid and more difficult to sell at an advantageous time or price or to value than higher-rated securities. In particular, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal.

6. INCOME TAX INFORMATION

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of each Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of February 28, 2017, attributable to the expiration of capital loss carryforwards and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

iShares ETF	Paid-in Capital		Undistributed Net Investment Income/Distributions in Excess of Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized Loss

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

As of February 28, 2017, the Funds had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates as follows:

^a Must be utilized prior to losses subject to expiration.

Management has analyzed tax laws and regulations and their application to the Funds as of February 28, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

Management’s Discussion of Fund Performance

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

U.S. BOND MARKET OVERVIEW

The U.S. bond market posted a modestly positive gain for the 12 months ended October 31, 2017 (“reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned 0.90%.

Improving economic growth and rising interest rates contributed to the U.S. bond market performance. The U.S. economy expanded by 2.3% for the 12 months ended September 2017 (the most recent data available), its fastest year-over-year growth rate in two years. The job market mirrored this progress, with the unemployment rate declining to its lowest level in more than 16 years. The healthier economy and job market contributed to consumer confidence reaching its highest level since January 2004, while retail sales increased by 4.6% for the reporting period.

On the manufacturing side, industrial output increased by 0.90% for the reporting period, reflecting a recovery in 2017 after industrial production contracted for much of 2016. At the same time, inflation was modest, with the consumer price index rising by 2.2% for the 12 months ended September 2017, well below the long-term historical average of 3.3%.

In that environment, the U.S. Federal Reserve Bank (“Fed”) worked to normalize monetary policy by beginning to reverse some of the measures taken in response to the 2008 financial crisis. The Fed increased interest rates by a quarter percentage point three times during the reporting period, from 0.5% to 1.25%, which contributed to higher short-term bond yields. The Fed also started reducing the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017.

Another catalyst for rising bond yields was the outcome of the U.S. presidential election in November 2016. The new administration was expected to enact pro-growth fiscal policies, including lower taxes and significant infrastructure spending, which was expected to lead to a higher federal budget deficit. Expectations of an increase in the supply of U.S. Treasury bonds, based on the government’s need to fill the larger budget gap, led to an increase in U.S. bond yields during the reporting period.

Overall, short-term U.S. Treasury bond yields rose more than long-term bond yields. For example, the yield of the two-year U.S. Treasury note increased from 0.86% to 1.6% over the course of the reporting period, while the yield of the 30-year U.S. Treasury bond rose less than half that amount, increasing from 2.58% to 2.88%. The yield difference, or spread, between short-term and longer-term U.S. Treasury securities reached levels not seen since before the 2008 financial crisis, when the Fed was raising short-term interest rates aggressively.

Interest rate trends had important implications for returns across the U.S. bond market. U.S. Treasury bonds declined for the reporting period and were the weakest performers among the broad market segments.

In contrast, economically sensitive corporate bonds performed well, benefiting from improving economic growth, healthy corporate profits, strong investor demand for their comparatively higher yields, and expectations of the new administration’s corporate-friendly policies. As a result, the yield spread between U.S. Treasury securities and corporate bonds — both investment-grade and high-yield — declined for the reporting period.

Mortgage-backed securities, which have higher yields than U.S. Treasury securities but greater sensitivity to interest rate changes than corporate bonds, finished between these two sectors, managing modest gains for the reporting period.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

The iShares Interest Rate Hedged 10+ Year Credit Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of investment-grade U.S. corporate bonds and U.S. dollar-denominated bonds, including those of non-U.S. corporations and governments, with remaining maturities greater than ten years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares 10+ Year Credit Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 11.36%, net of fees.

Investor demand for long-term, investment-grade bonds grew during the reporting period, contributing to the Fund’s return. The market for long-term debt benefited from better-capitalized pension funds seeking stable investments. While yields on long-term U.S. Treasuries increased, strong investor demand for yield reduced credit spreads (the additional yield on corporate bonds over similar-duration U.S. Treasuries), which helped support prices of long-term corporate bonds.

The Fund’s investments include both corporate and non-corporate bonds. Among corporate bonds, debt issued by industrial companies was the principal contributor to the Fund’s return for the reporting period. Among industrial companies, energy company bonds contributed the most, as oil prices stabilized in the $45-55 price range, which was sufficient for most oil companies to remain solvent. Bonds issued by firms in the consumer non-cyclicals, technology, and communications industries were also notable contributors to the Fund’s performance.

Financial company bonds also contributed significantly to the Fund’s return for the reporting period, with debt issued by the banks industry the primary contributor. Rising capital levels and reduced risk have made bank bonds more attractive for investors, sending the spread for U.S. banking bonds to the lowest level since the financial crisis.

Bonds issued by non-corporate entities, which represented approximately 15% of the Fund on average for the reporting period, also contributed to the Fund’s return for the reporting period. These issuers include supranationals, foreign governments, foreign agencies, and municipal agencies issuing taxable bonds.

Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling rates usually serve to increase bond prices. An interest rate hedged fund attempts to mitigate these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

Rising interest rates during the reporting period meant that hedging activity positively contributed to the Fund’s return. The Fund’s interest rate hedge seeks near-zero interest rate sensitivity and was successful within its targeted range. As a result, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund’s return fluctuated based on direct exposure to the yield premium of long-term, investment-grade bonds, independent of rising interest rates during the reporting period.

MANAGEMENT’S DISCUSSIONOF FUND PERFORMANCE 7

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Financial Statements

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
Interest Rate Hedged 10+ Year Credit Bond	Diversified

Currently the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an exchange-traded fund of iShares Trust (an “underlying fund”), an affiliate of the Fund. The financial statements and schedules of investments for the underlying fund can be found elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Exchange-traded funds and closed-end funds traded on a recognized securities exchange are valued at that day’s last reported trade price or the official closing price, as applicable, on the exchange where the fund is primarily traded. Funds traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

NOTESTO FINANCIAL STATEMENTS 15

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

• Swap agreements are valued utilizing quotes received daily by independent pricing services or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions from the underlying funds, if any, are recognized on the ex-dividend date. Interest income is accrued daily.

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

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

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

NOTESTO FINANCIAL STATEMENTS 17

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

borrower can resell or re-pledge the loaned securities, and a Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.35%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). The total of the investment advisory fee and acquired fund fees and expenses is the Fund’s total annual operating expenses. BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares 10+ Year Credit Bond ETF (“CLY”), after taking into account any fee waivers by CLY, plus 0.10%.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to 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, 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $364.

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

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends — affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BTC and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017, were $1,613,906 and $704,266, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2017, were $5,881,855 and $  —, respectively.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

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

5. INTEREST RATE SWAPS

Interest rate swaps are used by the Fund to mitigate the potential impact of interest rates on the performance of the bonds held by the Fund or its underlying fund. Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. Interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Swap agreements are privately negotiated in the over-the-counter market. The Fund enters into centrally cleared interest rate swaps.

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Fund’s counterparty on the swap. The Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the schedule of investments and cash deposited is recorded on the statement of assets and liabilities as cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the statement of assets and liabilities. Payments received from (paid to) the CCP, including at termination, are recorded as realized gain (loss) in the statement of operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the statement of assets and liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

20 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

7. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to the accounting for swap agreements, were reclassified to the following accounts:

Paid-in Capital	Undistributed Net Investment Income/Distributions in Excess of  Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized  Loss
$      —	$	(77,429)	$	77,429

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows.

	2017		2016
Ordinary income	$	352,551	$	200,730
Return of capital		7,976		6,500
	$	360,527	$	207,230

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

Capital Loss Carryforwards	Net Unrealized Gains  (Losses) a		Total
$ (758,135)	$	1,556,859	$	798,724

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

NOTESTO FINANCIAL STATEMENTS 21

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

As of October 31, 2017, the Fund had non-expiring capital loss carryforwards in the amount of $758,135 available to offset future realized capital gains.

For the year ended October 31, 2017, the Fund utilized $79,349 of its capital loss carryforwards.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ the claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the iShares Interest Rate Hedged 10+ Year Credit Bond ETF (constituting a fund of the iShares U.S. ETF Trust, hereafter referred to as the “Fund”) as of October 31, 2017, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the two years then ended and for the period July 22, 2015 (commencement of operations) through October 31, 2015, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Contract

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were higher than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board further noted that the Peer Group for the Fund contained only three comparison funds identified by Broadridge, excluding iShares funds.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board

Contract (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

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

Costs of Services Provided to Fund and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Fund to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on by the 15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through

Contract (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Contract at least annually, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded ETF, as compared to the Other Accounts that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to

Board Review and Approval of Investment Advisory

Contract (Continued)

iSHARES^® INTEREST RATE HEDGED 10+ YEAR CREDIT BOND ETF

Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Conclusion — Based on the considerations described above, the Board determined that the Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Contract for the coming year.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

iSHARES^® 10+ YEAR CREDIT BOND ETF

iShares Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated December 16, 1999.

These financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
10+ Year Credit Bond	Diversified

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of its underlying index. The investment adviser uses a “passive” or index approach to try to achieve the Fund’s investment objective.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

NOTESTO FINANCIAL STATEMENTS 105

Notes to Financial Statements (Continued)

iSHARES^® 10+ YEAR CREDIT BOND ETF

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration factors that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such factors are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

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

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

LOANS OF PORTFOLIO SECURITIES

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

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Fund may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of February 28, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of February 28, 2017 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. The Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

Securities lending transactions are entered into by the Fund under Master Securities Lending Agreements (“MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral

NOTESTO FINANCIAL STATEMENTS 107

Notes to Financial Statements (Continued)

iSHARES^® 10+ YEAR CREDIT BOND ETF

and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than that of the market value of the securities loaned, leaving the lender with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and the Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of February 28, 2017:

RECENT ACCOUNTING STANDARD

In March 2017, the Financial Accounting Standards Board issued an update to amend the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for premiums to the earliest call date, but do not require an accounting change for securities held at a discount. The amendments are effective for financial statements for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Management is evaluating the impact, if any, of this guidance on the Fund’s financial statements and disclosures.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

108 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Financial Statements (Continued)

iSHARES^® 10+ YEAR CREDIT BOND ETF

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.20% based on the average daily net assets of the Fund.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to 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, 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended February 28, 2017, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $77,907.

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

Cross trading is the buying or selling of portfolio securities between funds to which BFA (or an affiliate) serves as investment adviser. At its regularly scheduled quarterly meetings, the Board reviews such transactions as of the most recent calendar quarter for compliance with the requirements and restrictions set forth by Rule 17a-7.

For the year ended February 28, 2017, the purchases and sales transactions executed by the Fund pursuant to Rule 17a-7 under the 1940 Act were $2,717,770 and $1,755,962, respectively.

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BTC and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended February 28, 2017 were as follows:

U.S. Government Obligations				Other Securities
Purchases		Sales		Purchases		Sales
$	960,236	$	975,545	$	162,747,254	$	93,078,147

In-kind transactions (see Note 4) for the year ended February 28, 2017 were as follows:

In-kind Purchases		In-kind Sales
	$235,654,536	$	296,715,559

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

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

5. PRINCIPAL RISKS

In the normal course of business, the Fund’s investment activities expose it to various types of risk associated with the financial instruments and markets in which it invests. The significant types of financial risks the Fund is exposed to include market risk and credit risk. The Fund’s prospectus provides details of these and other types of risk.

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions,

110 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Financial Statements (Continued)

iSHARES^® 10+ YEAR CREDIT BOND ETF

economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Investing in the securities of non-U.S. issuers involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: generally less liquid and less efficient securities markets; generally greater price volatility; exchange rate fluctuations and exchange controls; imposition of restrictions on the expatriation of funds or other assets of the Fund; less publicly available information about issuers; the imposition of withholding or other taxes; higher transaction and custody costs; settlement delays and risk of loss attendant in settlement procedures; difficulties in enforcing contractual obligations; less regulation of securities markets; different accounting, disclosure and reporting requirements; more substantial governmental involvement in the economy; higher inflation rates; greater social, economic and political uncertainties; the risk of nationalization or expropriation of assets; and the risk of war. These risks are heightened for investments in issuers from countries with less developed markets.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Mortgage-backed securities and securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than other types of bonds or securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

6. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of February 28, 2017, attributable to realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

Paid-in Capital	Undistributed Net Investment Income/Distributions in Excess of Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized Loss
$7,844,421	$	902	$	(7,845,323)

The tax character of distributions paid during the years ended February 28, 2017 and February 29, 2016 was as follows:

	2017		2016
Ordinary income	$	38,936,880	$	34,627,351

As of February 28, 2017, the tax components of accumulated net earnings (losses) were as follows:

Undistributed Ordinary Income		Capital Loss Carryforwards		Net Unrealized Gains  (Losses) a		Total
	$2,903,195	$	(11,629,604)	$	(12,514,752)	$	(21,241,161)

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

As of February 28, 2017, the Fund had non-expiring capital loss carryforwards in the amount of $11,629,604 available to offset future realized capital gains.

Management has analyzed tax laws and regulations and their application to the Fund as of February 28, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

7. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

Shareholders of the iShares 10+ Year Credit Bond ETF

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the iShares 10+ Year Credit Bond ETF (constituting a fund of the iShares Trust, hereafter referred to as the “Fund”) as of February 28, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of February 28, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Management’s Discussion of Fund Performance

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

GLOBAL BOND MARKET OVERVIEW

Global investment-grade bonds posted modestly positive returns for the 12 months ended October 31, 2017 (“reporting period”), reflecting improving economic growth and rising interest rates in virtually all major bond markets. The Bloomberg Barclays Global Aggregate Index, a broad measure of global bond market performance, returned 1.18% in U.S. dollar terms for the reporting period.

Regionally, European bond markets posted the strongest returns among developed markets for the reporting period. European corporate bonds performed particularly well, benefiting from better economic conditions and stronger corporate earnings throughout Europe. The Eurozone economy expanded for the 12 months ended September 2017, its fastest growth rate in more than six years, and the jobless rate in September 2017 was the lowest since February 2009. The European Central Bank (“ECB”) elected to keep interest rates at historically low levels throughout the reporting period, though the ECB announced late in the reporting period that it plans to taper its quantitative easing program beginning in 2018. Currency fluctuations also contributed meaningfully to European bond performance in U.S. dollar terms as the euro appreciated by approximately 6% against the U.S. dollar during the reporting period.

In the U.S. bond market, economically sensitive corporate bonds performed well during the reporting period, benefiting from improving growth, healthy corporate profits, and strong investor demand for their comparatively higher yields. In contrast, U.S. Treasury securities declined and were the weakest performers among the broad market segments. The poor performance of U.S. Treasury bonds reflected concerns about the expected effect of the new presidential administration’s proposed tax cuts and fiscal stimulus policies. In addition, the U.S. Federal Reserve Bank (“Fed”) increased short-term interest rates by a quarter percentage point three times during the reporting period, from 0.5% to 1.25%, which contributed to higher short-term U.S. Treasury yields. The Fed also started reducing the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017. These actions were made possible by improvement in the U.S. economy, led by strength in the job market, where the unemployment rate reached its lowest level in more than 16 years.

Bond markets in the Asia-Pacific region rose modestly in U.S. dollar terms for the reporting period, reflecting modest economic growth, low inflation, and accommodative monetary policies in many countries. In fundamental terms, however, conditions were generally supportive of Japanese bond performance, as Japanese economic growth was 1.4% for the year ended in June, while consumer prices rose just 0.7% for the 12 months ended in September 2017. In that environment, the Bank of Japan maintained its economic stimulus measures, targeting negative short-term interest rates and zero percent yields on longer-term bonds. However, Japanese bond market performance was hindered by a decline in the Japanese yen, which depreciated by approximately 8% against the U.S. dollar.

The performance of inflation-linked securities during the reporting period was also noteworthy. U.S. Treasury inflation-indexed bonds declined as interest rates rose and inflation was generally modest — the U.S. consumer price index rose 2.2% for the 12 months ended September 2017, well below the long-term historical average. In contrast, European government inflation-linked bonds were among the strongest performers in global bond markets for the reporting period. This reflected a surge in U.K. inflation, where consumer prices rose at their fastest rate in more than five years.

The iShares Interest Rate Hedged Emerging Markets Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, emerging market bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares J.P. Morgan USD Emerging Markets Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 9.57%, net of fees.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

Latin American bonds made the most significant contribution to the Fund’s return for the reporting period, led by Argentina, Mexico, and Brazil. Argentina’s president, Mauricio Macri, made strides in his dual pledge to reduce inflation and stimulate economic growth during the reporting period. Having emerged from default in the previous reporting period, Argentina issued a 100-year bond yielding 7.9%, which was met with strong demand in an environment of low global bond yields. In Mexico, the U.S. presidential election and Donald Trump’s proposed trade policies initially drove Mexican bond yields up and the Mexican peso down, but slow progress and softer trade rhetoric alleviated concerns, helping Mexican bonds rebound for the reporting period. Brazilian bonds benefited from a declining inflation rate and the anticipation of future reductions in interest rates by the central bank, despite concerns surrounding political crises.

European bonds also contributed meaningfully to the Fund’s performance for the reporting period, led by Ukraine. The country’s first sovereign bond issue since restructuring its debt in 2015 attracted strong investor demand, benefiting from continued investor appetite for yield. Russian Federation bonds also contributed to the Fund’s return.

Bonds from the Middle East and Asia were noteworthy contributors to the Fund’s performance for the reporting period as well, driven by Kazakhstan and Indonesia. Africa’s contribution to the Fund’s return was led by Zambia.

Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling rates usually tend to increase bond prices. An interest rate hedged fund attempts to mitigate these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

Rising interest rates during the reporting period meant that hedging activity contributed positively to the Fund’s return. The Fund’s interest rate hedge seeks near-zero interest rate sensitivity and was successful within its targeted range. As a result, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund’s return fluctuated based on direct exposure to the yield premium of emerging market bonds, independent of rising interest rates during the reporting period.

MANAGEMENT’S DISCUSSIONOF FUND PERFORMANCE 7

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Financial Statements

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
Interest Rate Hedged Emerging Markets Bond	Non-diversified

Currently the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an exchange-traded fund of iShares Trust (an “underlying fund”), an affiliate of the Fund. The financial statements and schedules of investments for the underlying fund can be found elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Exchange-traded funds and closed-end funds traded on a recognized securities exchange are valued at that day’s last reported trade price or the official closing price, as applicable, on the exchange where the fund is primarily traded. Funds traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

• Swap agreements are valued utilizing quotes received daily by independent pricing services or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions from the underlying funds, if any, are recognized on the ex-dividend date. Interest income is accrued daily.

Notes to Financial Statements (Continued)

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

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

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

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.75%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). The total of the investment advisory fee and acquired fund fees and expenses is the Fund’s total annual operating expenses. BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares J.P. Morgan USD Emerging Markets Bond ETF (“EMB”), after taking into account any fee waivers by EMB, plus 0.10%.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to 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, 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $813.

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

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BTC and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017, were $257,173 and $49,960, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2017, were $2,381,820 and $2,464,471, respectively.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

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

5. INTEREST RATE SWAPS

Interest rate swaps are used by the Fund to mitigate the potential impact of interest rates on the performance of the bonds held by the Fund or its underlying fund. Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. Interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Swap agreements are privately negotiated in the over-the-counter market. The Fund enters into centrally cleared interest rate swaps.

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Fund’s counterparty on the swap. The Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the schedule of investments and cash deposited is recorded on the statement of assets and liabilities as cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the statement of assets and liabilities. Payments received from (paid to) the CCP, including at termination, are recorded as realized gain (loss) in the statement of operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the statement of assets and liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

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

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

7. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to the accounting for swap agreements, distributions paid in excess of taxable income, and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

Paid-in Capital	Undistributed Net Investment Income/ Distributions in Excess of Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized  Loss
$    105,541	$	(13,614)	$	(91,927)

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

	2017		2016
Ordinary income	$	114,001	$	88,749
Return of capital		—		2,962
	$	114,001	$	91,711

NOTESTO FINANCIAL STATEMENTS 21

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

Capital Loss Carryforwards		Net Unrealized Gains  (Losses) a		Total
$	(29,066)	$	110,304	$	81,238

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

As of October 31, 2017, the Fund had non-expiring capital loss carryforwards in the amount of $29,066 available to offset future realized capital gains.

For the year ended October 31, 2017, the Fund utilized $112,226 of its capital loss carryforwards.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the iShares Interest Rate Hedged Emerging Markets Bond ETF (constituting a fund of the iShares U.S. ETF Trust, hereafter referred to as the “Fund”) as of October 31, 2017, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the two years then ended and for the period July 22, 2015 (commencement of operations) through October 31, 2015, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Board Review and Approval of Investment Advisory

Contract

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

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

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in

comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

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

Costs of Services Provided to Fund and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Fund to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on by the 15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in

iSHARES^® INTEREST RATE HEDGED EMERGING MARKETS BOND ETF

the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Contract at least annually, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded ETF, as compared to the Other Accounts that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be

disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Conclusion — Based on the considerations described above, the Board determined that the Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Contract for the coming year.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

FINANCIAL HIGHLIGHTS 49

Notes to Financial Statements

iSHARES^® J.P. MORGAN USD EMERGING MARKETS BOND ETF

iShares Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated December 16, 1999.

These financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
J.P. Morgan USD Emerging Markets Bond		Non-diversified

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of its underlying index. The investment adviser uses a “passive” or index approach to try to achieve the Fund’s investment objective.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

Notes to Financial Statements (Continued)

iSHARES^® J.P. MORGAN USD EMERGING MARKETS BOND ETF

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

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

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, and payment-in-kind interest income, are recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

RECENT ACCOUNTING STANDARD

In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on Purchase Callable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchased callable debt securities that have explicit, non-contingent call features and are callable at fixed prices will be amortized to the earliest call date. The guidance will be applied on a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management is currently evaluating the impact of this guidance to the Fund.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee, accrued daily and paid monthly by the Fund, based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Investment Advisory Fee			Aggregate Average Daily Net Assets
	0.4000	%	First $19 billion
	0.3800	a	Over $19 billion, up to and including $33  billion
	0.3610	a	Over $33 billion, up to and including $47  billion
	0.3430	a	Over $47 billion

^a  Investment advisory fee level reflects a 5% reduction (rounded to the fourth decimal place) from the investment advisory fee at the prior aggregate average daily net asset level.

Notes to Financial Statements (Continued)

iSHARES^® J.P. MORGAN USD EMERGING MARKETS BOND ETF

Prior to August 4, 2017, for its investment advisory services to the Fund, BFA was entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Investment Advisory Fee			Aggregate Average Daily Net Assets
	0.6000	%	First $19 billion
	0.5700	a	Over $19 billion, up to and including $33  billion
	0.5415	a	Over $33 billion, up to and including $47  billion
	0.5145	a	Over $47 billion

^a  Investment advisory fee level reflects a 5% reduction (rounded to the fourth decimal place) from the investment advisory fee at the prior aggregate average daily net asset level.

The total of the investment advisory fee and any other fund expenses are the Fund’s total annual operating expenses. BFA contractually agreed to waive a portion of its investment advisory fee for the Fund through February 28, 2023 in order to limit total annual operating expenses to 0.40% of average daily net assets. The contractual waiver was terminated effective August 4, 2017, pursuant to a written agreement between the Trust and BFA, and in conjunction with the annual advisory fee reduction from 0.60% to 0.40%.

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

Cross trading is the buying or selling of portfolio securities between funds to which BFA (or an affiliate) serves as investment adviser. At its regularly scheduled quarterly meetings, the Board reviews such transactions as of the most recent calendar quarter for compliance with the requirements and restrictions set forth by Rule 17a-7.

For the year ended October 31, 2017, the purchase and sales transactions executed by the Fund pursuant to Rule 17a-7 under the 1940 Act were $ 99,543,347 and $ 84,656,531, respectively.

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BlackRock Institutional Trust Company, N.A. and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017, were $3,028,524,860 and $2,686,796,990, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2017, were $9,401,000,260 and $7,460,398,396, respectively.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

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

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind contributions are reflected as “Due from custodian” and securities related to in-kind redemptions are reflected as “Securities related to in-kind transactions” in the statement of assets and liabilities.

5. PRINCIPAL RISKS

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

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Investing in the securities of non-U.S. issuers involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: differences in accounting, auditing and financial reporting standards; more substantial governmental involvement in the economy; higher inflation rates, greater social, economic and political uncertainties; possible nationalization or expropriation of assets; less availability of public information about issuers; imposition of withholding or other taxes; higher transaction and custody costs and delays in settlement procedures; and lower level of regulation of the securities markets and issuers. Non-U.S. securities may be less liquid, more difficult to value, and have greater price volatility due to exchange rate fluctuations. These and other risks are heightened for investments in issuers from countries with less developed capital markets.

The United States and the European Union, along with the regulatory bodies of a number of countries including Japan, Australia, Norway, Switzerland and Canada, have imposed economic sanctions, which consist of asset freezes and sectorial sanctions, on certain Russian individuals and Russian corporate entities. Broader sanctions on Russia could also be instituted. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. Current or future sanctions may result in Russia taking counter measures or retaliatory actions, which may further impair the value and liquidity of Russian securities. These retaliatory measures may include the immediate freeze of Russian assets held by a fund.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

High yield securities that are rated below investment-grade (commonly referred to as “junk bonds”) or are unrated may be deemed speculative, involve greater levels of risk than higher-rated securities of similar maturity and are more likely to default. High yield securities may be issued by less creditworthy issuers, and issuers of high yield securities may be unable to meet their interest or principal payment obligations. High yield securities are subject to extreme price fluctuations, may be less liquid than higher rated fixed-income securities, even under normal economic conditions, and frequently have redemption features.

6. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

Paid-in Capital		Undistributed Net Investment Income/Distributions in Excess of Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized  Loss
$	80,798,328	$	2,818	$	(80,801,146)

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

	2017		2016
Ordinary income	$	472,368,085	$	321,652,097

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

Undistributed Ordinary Income		Capital Loss Carryforwards			Net Unrealized Gains (Losses) a		Total
$	37,564,496	$	(141,515,293	)	$	11,102,238	$	(92,848,559	)

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales.

As of October 31, 2017, the Fund had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates as follows:

Non- Expiring a		Expiring 2018		Total
	$141,419,263	$	96,030	$	141,515,293

^a  Must be utilized prior to losses subject to expiration.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

7. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

Management’s Discussion of Fund Performance

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

U.S. BOND MARKET OVERVIEW

The U.S. bond market posted a modestly positive gain for the 12 months ended October 31, 2017 (“reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned 0.90%.

Improving economic growth and rising interest rates contributed to the U.S. bond market performance. The U.S. economy expanded by 2.3% for the 12 months ended September 2017 (the most recent data available), its fastest year-over-year growth rate in two years. The job market mirrored this progress, with the unemployment rate declining to its lowest level in more than 16 years. The healthier economy and job market contributed to consumer confidence reaching its highest level since January 2004, while retail sales increased by 4.6% for the reporting period.

On the manufacturing side, industrial output increased by 0.90% for the reporting period, reflecting a recovery in 2017 after industrial production contracted for much of 2016. At the same time, inflation was modest, with the consumer price index rising by 2.2% for the 12 months ended September 2017, well below the long-term historical average of 3.3%.

In that environment, the U.S. Federal Reserve Bank (“Fed”) worked to normalize monetary policy by beginning to reverse some of the measures taken in response to the 2008 financial crisis. The Fed increased interest rates by a quarter percentage point three times during the reporting period, from 0.5% to 1.25%, which contributed to higher short-term bond yields. The Fed also started reducing the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017.

Another catalyst for rising bond yields was the outcome of the U.S. presidential election in November 2016. The new administration was expected to enact pro-growth fiscal policies, including lower taxes and significant infrastructure spending, which was expected to lead to a higher federal budget deficit. Expectations of an increase in the supply of U.S. Treasury bonds, based on the government’s need to fill the larger budget gap, led to an increase in U.S. bond yields during the reporting period.

Overall, short-term U.S. Treasury bond yields rose more than long-term bond yields. For example, the yield of the two-year U.S. Treasury note increased from 0.86% to 1.6% over the course of the reporting period, while the yield of the 30-year U.S. Treasury bond rose less than half that amount, increasing from 2.58% to 2.88%. The yield difference, or spread, between short-term and longer-term U.S. Treasury securities reached levels not seen since before the 2008 financial crisis, when the Fed was raising short-term interest rates aggressively.

Interest rate trends had important implications for returns across the U.S. bond market. U.S. Treasury bonds declined for the reporting period and were the weakest performers among the broad market segments.

In contrast, economically sensitive corporate bonds performed well, benefiting from improving economic growth, healthy corporate profits, strong investor demand for their comparatively higher yields, and expectations of the new administration’s corporate-friendly policies. As a result, the yield spread between U.S. Treasury securities and corporate bonds — both investment-grade and high-yield — declined for the reporting period.

Mortgage-backed securities, which have higher yields than U.S. Treasury securities but greater sensitivity to interest rate changes than corporate bonds, finished between these two sectors, managing modest gains for the reporting period.

The iShares Edge U.S. Fixed Income Balanced Risk ETF (the “Fund”) seeks total return and preservation of capital by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar denominated investment-grade and high-yield fixed-income securities that in the aggregate has approximately equal exposure to credit spread risk and interest rate risk. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 2.79%, net of fees.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

During the reporting period, the Fund outperformed the broader bond market. One contributing factor was less exposure to interest rate fluctuations than the broader market. This contributed to the Fund’s performance as interest rates rose 0.60%–0.80% across most maturity sectors. Bond prices generally decline as interest rates increase.

The Fund’s greater exposure to investment-grade corporate bonds during the reporting period, relative to the broader bond market, contributed to the Fund’s return as corporate bonds posted solid gains. Within the investment-grade corporate sector, security selection also contributed to the Fund’s return. However, a higher allocation to short-term investment-grade bonds detracted from the Fund’s performance as short-term bond yields increased more than intermediate- and long-term bond yields.

Exposure to high-yield corporate bonds, which were the best performers in the U.S. bond market, also contributed to the Fund’s performance during the reporting period. In addition, security selection within the high-yield corporate sector benefited the Fund’s return. Within the government agency mortgage-backed securities (“MBS”) sector, however, security selection detracted from the Fund’s return.

The strong performance of investment-grade and high-yield corporate bonds led to increased risk levels in these sectors, while risk levels moderated among agency MBS. Because the managers allocate risk equally among each credit sector, the Fund’s allocation to intermediate-term investment-grade corporate bonds declined, and the allocation to agency MBS increased during the reporting period. Allocations to short-term investment-grade corporate debt and high-yield corporate bonds were both relatively unchanged for the reporting period.

Subsequent Event: The Fund is expected to be converted from an actively managed exchange-traded fund (“ETF”) to a passively managed or index ETF through a reorganization to be completed during the first quarter of 2018. The Fund currently has an investment objective of seeking total return and preservation of capital. It seeks to achieve this objective by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar-denominated investment-grade and high-yield fixed-income securities. Following its reorganization into an index ETF, the Fund will generally invest at least 90% if its assets in the component securities of the Bloomberg Barclays U.S. Fixed Income Balanced Risk Index, an index primarily composed of U.S. dollar-denominated investment-grade and high yield fixed-income securities. The change in investment objective is not expected to have a significant effect on the Fund’s investments or the risks related to such investments. For more information on the reorganization, please see Note 9 in the notes to financial statements.

MANAGEMENT’S DISCUSSIONOF FUND PERFORMANCE 7

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Financial Statements

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
Edge U.S. Fixed Income Balanced Risk	Non-diversified

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

NOTESTO FINANCIAL STATEMENTS 31

Notes to Financial Statements (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

• Futures contract notional values are determined based on that day’s last reported settlement price on the exchange where the contract is traded.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, and payment-in-kind interest income, are recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

WHEN-ISSUED/TBA TRANSACTIONS

The Fund may purchase mortgage pass-through securities on a when-issued or to-be-announced (“TBA”) basis, with payment and delivery scheduled for a future date. The Fund may enter into a TBA agreement, sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities (a “TBA roll”). A TBA roll is treated by the Fund as a purchase transaction and a sale transaction in which the Fund realizes a gain or loss. The Fund’s use of TBA rolls may cause the Fund to experience higher portfolio turnover and higher transaction costs. The Fund could be exposed to possible risk if there are adverse market actions, expenses or delays in connection with the TBA transactions, or if the counterparty fails to complete the transaction.

To mitigate counterparty risk, the Fund has entered into a two-way collateral agreement for TBA transactions with certain counterparties. Under such agreement, the “in-the-money” party of a TBA transaction may at any time require the other party to pledge collateral assets (in the form of cash or securities) to offset any loss the in-the-money party would incur upon cancellation of the TBA transaction. A party is in-the-money if they are the buyer and the market value of the TBA transaction increases or if they are the seller and the market value of the TBA transaction decreases. Cash received as collateral from the counterparty may be reinvested in money market funds, including those managed by the Fund’s investment adviser, or its affiliates. Such collateral, if any, is presented in the statement of assets and liabilities as “Investments in securities – affiliated” and “Payable due to broker for TBA collateral.” Securities pledged as collateral by the Fund, if any, are noted in the schedule of investments.

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors

NOTESTO FINANCIAL STATEMENTS 33

Notes to Financial Statements (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

(“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

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

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

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2017:

RECENT ACCOUNTING STANDARD

In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on Purchase Callable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchased callable debt securities that have explicit, non-contingent call features and are callable at fixed prices will be amortized to the earliest call date. The guidance will be applied on a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management is currently evaluating the impact of this guidance to the Fund.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.25%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to waive a portion of its investment advisory fees for the Fund through February 29, 2024 in an amount equal to the acquired fund fees and expenses, if any, attributable to the Fund’s investments in other registered investment companies advised by BFA or its affiliates.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to 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, 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $9,653.

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

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017 were as follows:

U.S. Government Obligations				Other Securities
Purchases		Sales		Purchases		Sales
$	960,796,811	$	931,652,487	$	64,277,765	$	16,484,773

There were no in-kind transactions (see Note 4) for the year ended October 31, 2017.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

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

5. FUTURES CONTRACTS

The Fund uses futures contracts to balance its exposure to interest rate risk against its exposure to credit spread risk. Futures contracts are standardized, exchange-traded agreements to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, a fund is required to pledge to the executing broker which holds segregated from its own assets, an amount of cash, U.S. government securities or other high-quality debt and equity securities equal to the minimum initial margin requirements of the exchange on which the contract is traded.

Pursuant to the contract, the fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in notional value of the contract. Such receipts or payments are known as margin variation and are recorded by the fund as unrealized appreciation or depreciation. When the contract is closed, the fund records a realized gain or loss equal to the difference between the notional value of the contract at the time it was opened and the notional value at the time it was closed.

Notes to Financial Statements (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

Losses may arise if the notional value of a futures contract decreases due to an unfavorable change in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk of an imperfect correlation in the movements in the price of futures contracts and the assets underlying such contracts.

The following table shows the value of futures contracts held by the Fund as of October 31, 2017 and the related locations in the statement of assets and liabilities, presented by risk exposure category:

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Investing in the securities of non-U.S. issuers involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: differences in accounting, auditing and financial reporting standards; more substantial governmental involvement in the economy; higher inflation rates, greater social, economic and political uncertainties; possible nationalization or expropriation of assets; less availability of public information about issuers; imposition of withholding or other taxes; higher transaction and custody costs and delays in settlement procedures; and lower level of regulation of the securities markets and issuers. Non-U.S. securities may be less liquid, more difficult to value, and have greater price volatility due to exchange rate fluctuations. These and other risks are heightened for investments in issuers from countries with less developed capital markets.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

High yield securities that are rated below investment-grade (commonly referred to as “junk bonds”) or are unrated may be deemed speculative, involve greater levels of risk than higher-rated securities of similar maturity and are more likely to default. High yield securities may be issued by less creditworthy issuers, and issuers of high yield securities may be unable to meet their interest or principal payment obligations. High yield securities are subject to extreme price fluctuations, may be less liquid than higher rated fixed-income securities, even under normal economic conditions, and frequently have redemption features.

7. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017 were reclassified to the following accounts:

Undistributed Net Investment Income/Distributions in Excess of Net Investment Income	Undistributed Net Realized Gain/Accumulated Net Realized Loss
$                                7	$	(7)

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

	2017		2016
Ordinary income	$	2,967,987	$	1,954,073
Return of capital		28,701		64,951
	$	2,996,688	$	2,019,024

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

Net Unrealized Gains (Losses) a		Total
$	1,032,910	$	1,032,910

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains (losses) on certain futures contracts.

For the year ended October 31, 2017, the Fund utilized $260,711 of its capital loss carryforwards.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF,

The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements, except as noted below.

On September 15, 2017, the Board approved a proposal to convert the Fund, a series of the Trust, from operating as an actively managed exchange-traded fund (“ETF”) to a passively managed or index ETF through a reorganization pursuant to which the Fund’s assets would be acquired, and its liabilities would be assumed, by a newly created series (the “New Fund”) of iShares Trust. The transaction is expected to be tax-free for U.S. federal income tax purposes. If the reorganization is completed, shareholders of the Fund would receive shares of the New Fund with equivalent value, both measured immediately prior to the time of the reorganization. Consummation of the reorganization will be subject to a number of conditions. Shareholders of the Fund are not required to vote with respect to the reorganization and no shareholder vote is being sought on this matter. BlackRock will bear all of the expenses of the reorganization. The reorganization is currently expected to be completed during the first quarter of 2018.

Shareholders of the iShares Edge U.S. Fixed Income Balanced Risk ETF

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the iShares Edge U.S. Fixed Income Balanced Risk ETF (constituting a fund of the iShares U.S. ETF Trust, hereafter referred to as the “Fund”) as of October 31, 2017, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the two years then ended and for the period February 24, 2015 (commencement of operations) through October 31, 2015, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Board Review and Approval of Investment Advisory

Contract

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

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

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in

BOARD REVIEWAND APPROVALOF INVESTMENT ADVISORY CONTRACT 43

Board Review and Approval of Investment Advisory

Contract (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

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

Costs of Services Provided to Fund and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Fund to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on by the 15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional

Contract (Continued)

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Contract at least annually, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do manage Other Accounts with similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded ETF, as compared to the Other Accounts that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be

iSHARES^® EDGE U.S. FIXED INCOME BALANCED RISK ETF

disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Conclusion — Based on the considerations described above, the Board determined that the Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Contract for the coming year.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

GLOBAL EQUITY MARKET OVERVIEW

Global equity markets posted strong returns for the 12 months ended October 31, 2017 (“reporting period”). The MSCI ACWI, a broad global equity index that includes both developed and emerging markets, returned 23.2% in U.S. dollar terms for the reporting period.

The key factor behind the robust performance of global stocks during the reporting period was improving global economic growth, which was driven largely by the continuation of accommodative monetary policies from many of the world’s central banks. Stronger economic activity in Europe emerged during the reporting period as the European Central Bank (“ECB”) maintained policies such as quantitative easing and negative interest rates. Economic growth rates in China and Japan, the largest economies in Asia, also increased during the reporting period, reflecting efforts by the People’s Bank of China (“PBOC”) and the Bank of Japan to stimulate economic activity.

By the end of the reporting period, stronger economic growth led several central banks to reduce some of their economic stimulus measures. For example, the ECB announced plans to taper its quantitative easing program beginning in 2018, while the PBOC increased short-term interest rates during the first half of 2017.

On a regional basis, European equity markets posted the strongest returns among developed markets, advancing by approximately 27% in U.S. dollar terms for the reporting period. European stocks benefited from improving economic conditions and stronger corporate earnings. In addition, election outcomes in France and the Netherlands eased investor concerns about nationalist presidential candidates and their opposition to the European Union. Currency fluctuations also contributed meaningfully to European equity performance in U.S. dollar terms as the euro appreciated by approximately 6% against the U.S. dollar during the reporting period. The best-performing European stock markets included Austria, Italy, and France, while Belgium and Switzerland posted modest returns.

Equity markets in the Asia-Pacific region gained about 18% in U.S. dollar terms for the reporting period, led by Singapore and Hong Kong. Japanese stocks also posted strong returns, benefiting from improving consumer spending and employment trends that contributed to the ongoing recovery in the Japanese economy. However, equity market returns in Japan were hindered by a decline in the Japanese yen, which depreciated by approximately 8% against the U.S. dollar for the reporting period.

The U.S. stock market returned approximately 23% for the reporting period. U.S. stocks advanced initially in anticipation of pro-business fiscal policies from the new presidential administration. Although the administration struggled to implement its fiscal agenda, stocks continued to move higher as global economic growth led to a notable improvement in corporate earnings growth, particularly for multinational companies with significant operations outside of the U.S. U.S. stocks advanced despite three short-term interest rate increases by the U.S. Federal Reserve Bank (“Fed”) during the reporting period, which increased its short-term interest rate target to its highest levels since October 2008. The Fed also began to reduce the amount of U.S. Treasury bonds and mortgage-backed securities on its balance sheet in October 2017.

Emerging markets stocks outperformed those in developed markets, returning more than 26% in U.S. dollar terms for the reporting period. Emerging markets in Asia posted the best returns, led by China and South Korea. Equity markets in the Middle East trailed for the reporting period amid continued geopolitical conflict in the region.

Management’s Discussion of Fund Performance (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

The iShares Commodities Select Strategy ETF (the “Fund”) seeks total return by providing investors with broad commodity exposure. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2017, the total return for the Fund was 12.08%, net of fees.

Approximately 70% of the Fund’s exposure was in commodities futures, which were solid contributors to the Fund’s return for the reporting period. Some of the Fund’s largest exposures in the futures portion of the portfolio during the reporting period included West Texas Intermediate crude oil, Brent crude oil, heating oil, gas oil, and unleaded gasoline. These futures positions benefited from an overall increase in energy prices, despite some volatility. Oil prices initially declined during the first half of 2017 as inventories increased and supply reflected increased output by Libya, Nigeria, and U.S. shale oil producers. But these conditions reversed beginning in July 2017, when OPEC announced additional production cuts, U.S. oil inventories declined, hurricanes in the U.S. disrupted refinery activity, and political uncertainty in Venezuela all led to increased prices. Limited output from U.S. oil refiners and record demand during the summer driving season led to gasoline prices in the U.S. reaching a two-year high in August 2017. Demand for energy more broadly was supported by improving global economic growth during the reporting period. Agricultural commodities generally weakened during the reporting period due to excess supply, as wheat inventories reached near-record highs and international production surged.

Approximately 30% of the Fund’s exposure was in commodities stocks, which were strong contributors to the Fund’s return for the reporting period. The stocks of companies in the agricultural and farm machinery and fertilizers and agricultural chemicals industries were meaningful contributors to the Fund’s return despite weakening prices for agricultural commodities. Demand for both farming and industrial equipment and fertilizer reflected improved global growth, particularly in South America. Stocks in the metals and mining industry also contributed to the Fund’s return for the reporting period, largely reflecting positive pricing for industrial commodities such as aluminum and copper. Metals prices increased due to strong demand from China, which simultaneously constrained supply by closing factories to address environmental concerns.

MANAGEMENT’S DISCUSSIONOF FUND PERFORMANCE 7

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

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

Shareholder Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2017 and held through October 31, 2017, is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

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

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

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

Notes to Consolidated Financial Statements

iSHARES^® COMMODITIES SELECT STRATEGY ETF

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These consolidated financial statements relate only to the following fund (the “Fund”):

iShares ETF	Diversification Classification
Commodities Select Strategy	Diversifieda

^a  The Fund’s classification changed from non-diversified to diversified during the reporting period.

The Fund carries out its investment strategies associated with investment in commodity futures contracts and other derivatives (“commodity-linked investments”) by investing up to 25% of its total assets in iShares Commodities Strategy Cayman Ltd., a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The investment adviser of the Fund also serves as the investment adviser to the Subsidiary. Investments in the Subsidiary enable the Fund to hold the commodity-linked investments and satisfy regulated investment company tax requirements. The accompanying consolidated schedule of investments and consolidated financial statements for the Fund include the positions and accounts, respectively, of its Subsidiary. Intercompany accounts and transactions, if any, have been eliminated.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

1. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

SECURITY VALUATION

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

• Equity investments traded on a recognized securities exchange are valued at that day’s last reported trade price or the official closing price, as applicable, on the exchange where the stock is primarily traded. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.

NOTESTO CONSOLIDATED FINANCIAL STATEMENTS 19

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

• Fixed income investments are valued using the last available bid price or current market quotations provided by dealers or prices (including evaluated prices) supplied by approved independent third-party pricing services. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, 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 a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

• Open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

• Futures contract notional values are determined based on that day’s last reported settlement price on the exchange where the contract is traded.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued based upon other available factors deemed relevant by the Global Valuation Committee, in accordance with policies approved by the Board. These factors include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such factors are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for a financial instrument within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The categorization of a value determined for a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and is not necessarily an indication of the risk associated with investing in the instrument. The three levels of the fair value hierarchy are as follows:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 — Unobservable inputs for the asset or liability based on the best information available in the circumstances, to the extent observable inputs are not available, including the Global Valuation Committee’s assumptions used in determining the fair value of investments.

20 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its consolidated schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source. Any taxes withheld that are reclaimable from foreign tax authorities as of October 31, 2017 are reflected in tax reclaims receivable. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be re-designated as a reduction of cost of the related investment and/or realized gain. Non-cash dividends, if any, are recognized on the ex-dividend date and recorded as non-cash dividend income at fair value. Distributions received by the Fund may include a return of capital that is estimated by management. Such amounts are recorded as a reduction of the cost of investments or reclassified to capital gains. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on the accrual basis.

FOREIGN CURRENCY TRANSLATION

The accounting records of the Fund are maintained in U.S. dollars. Foreign currencies, as well as investment securities and other assets and liabilities denominated in foreign currencies, are translated into U.S. dollars using exchange rates deemed appropriate by the investment adviser. Purchases and sales of securities, income receipts and expense payments are translated into U.S. dollars on the respective dates of such transactions.

The Fund does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of securities. Such fluctuations are reflected by the Fund as a component of realized and unrealized gains and losses from investments for financial reporting purposes. The Fund reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.

FOREIGN TAXES

The Fund may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Fund invests. These foreign taxes, if any, are paid by the Fund and are reflected in its consolidated statement of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of October 31, 2017, if any, are disclosed in the Fund’s consolidated statement of assets and liabilities.

NOTESTO CONSOLIDATED FINANCIAL STATEMENTS 21

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

DISTRIBUTIONS TO SHAREHOLDERS

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

LOANS OF PORTFOLIO SECURITIES

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

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2017, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the consolidated schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund are also disclosed in its consolidated schedule of investments. The total value of any securities on loan as of October 31, 2017 and the total value of the related cash collateral are disclosed in the consolidated statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the consolidated statement of operations.

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

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

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

The Subsidiary has entered into a separate contract with BFA under which BFA provides investment advisory services to the Subsidiary but does not receive separate compensation from the Subsidiary for providing it with such services. The Subsidiary has also entered into separate arrangements that provide for the provision of other services to the Subsidiary (including administrative, custody, transfer agency and other services), and BFA pays the costs and expenses related to the provision of those services.

BFA has entered into a sub-advisory agreement with BlackRock International Limited (the “Sub-Adviser”), an affiliate of BFA, under which BFA pays the Sub-Adviser for services it provides to the Fund and the Subsidiary.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.48%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. In addition, the Fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to waive a portion of its investment advisory fees for the Fund through February 29, 2024 in an amount equal to the acquired fund fees and expenses, if any, attributable to the Fund’s investments in other registered investment companies advised by BFA or its affiliates.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. The Fund is responsible for fees in

NOTESTO CONSOLIDATED FINANCIAL STATEMENTS 23

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2017, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $7,323.

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

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the consolidated statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BTC and/or BFA.

3. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2017, were $27,993,606 and $34,933,395, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2017, were $44,472,451 and $70,242,420, respectively.

4. CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the consolidated statements of changes in net assets.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for

24 2017 iSHARES ANNUAL REPORTTO SHAREHOLDERS

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” in the consolidated statements of changes in net assets.

5. FUTURES CONTRACTS

The Fund invests in commodity futures contracts to gain exposure to the applicable commodities markets. Futures contracts are standardized, exchange-traded agreements to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, a fund is required to pledge to the executing broker which holds segregated from its own assets, an amount of cash, U.S. government securities or other high-quality debt and equity securities equal to the minimum initial margin requirements of the exchange on which the contract is traded.

Pursuant to the contract, the fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in notional value of the contract. Such receipts or payments are known as margin variation and are recorded by the fund as unrealized appreciation or depreciation. When the contract is closed, the fund records a realized gain or loss equal to the difference between the notional value of the contract at the time it was opened and the notional value at the time it was closed. Losses may arise if the notional value of a futures contract decreases due to an unfavorable change in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk of an imperfect correlation in the movements in the price of futures contracts and the assets underlying such contracts.

6. PRINCIPAL RISKS

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

MARKET RISK

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

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

Investing in the securities of non-U.S. issuers involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: differences in accounting, auditing and financial reporting standards; more substantial governmental involvement in the economy; higher inflation rates, greater social, economic and political uncertainties; possible nationalization or expropriation of assets; less availability of public information about issuers; imposition of withholding or other taxes; higher transaction and custody costs and delays in settlement procedures; and lower level of regulation of the securities markets and issuers. Non-U.S. securities may be less liquid, more difficult to value, and have greater price volatility due to exchange rate fluctuations. These and other risks are heightened for investments in issuers from countries with less developed capital markets.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

The Fund invests in instruments and companies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets that may be due to changes in supply and demand for the commodities, market events, regulatory developments or other factors that the Fund cannot control could have an adverse impact on those companies.

iSHARES^® COMMODITIES SELECT STRATEGY ETF

CREDIT RISK

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

7. INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

Net income and realized gains from investments held by the Subsidiary are treated as ordinary income for tax purposes and any net income or net gains will pass through to the Fund as such. Accordingly, the net investment income (loss) and realized gains (losses) reported in the Fund’s financial statements for such investments held by the Subsidiary may differ significantly from distributions. In addition, if a net loss is realized by the Subsidiary in any taxable year, the loss will not be available to offset the Fund’s ordinary income and/or capital gains for that year.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2017, attributable to the characterization of corporate actions, passive foreign investment companies, the character of income (losses) from the Subsidiary and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

Paid-in Capital	Undistributed Net Investment Income/Distributions in Excess of Net Investment Income		Undistributed Net Realized Gain/Accumulated Net Realized Loss
$(3,382,574)	$	12,599,052	$	(9,216,478)

The tax character of distributions paid during the years ended October 31, 2017 and October 31, 2016 was as follows:

	2017		2016
Ordinary income	$	1,863,172	$	1,347,562

NOTESTO CONSOLIDATED FINANCIAL STATEMENTS 27

Notes to Consolidated Financial Statements (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

As of October 31, 2017, the tax components of accumulated net earnings (losses) were as follows:

Undistributed Ordinary Income		Capital Loss Carryforwards		Net Unrealized Gains  (Losses) a		Total
$	11,824,645	$	(20,611,420)	$	11,048,885	$	2,262,110

^a  The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales, the characterization of corporate actions and the realization for tax purposes of unrealized gains on investments in passive foreign investment companies.

As of October 31, 2017, the Fund had non-expiring capital loss carryforwards in the amount of $20,611,420 available to offset future realized capital gains.

The Fund may own shares in certain foreign investment entities, referred to, under U.S. tax law, as “passive foreign investment companies.” The Fund may elect to mark-to-market annually the shares of each passive foreign investment company and would be required to distribute to shareholders any such marked-to-market gains.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2017, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s consolidated financial statements.

8. LEGAL PROCEEDINGS

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”). The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the Court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the Court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the Court’s decision.

9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the date the consolidated financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the consolidated financial statements.

Shareholders of the iShares Commodities Select Strategy ETF

In our opinion, the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, and the related consolidated statements of operations and of changes in net assets and the consolidated financial highlights present fairly, in all material respects, the financial position of the iShares Commodities Select Strategy ETF and its subsidiary (constituting a fund of the iShares U.S. ETF Trust, hereafter referred to as the “Fund”) as of October 31, 2017, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended and the financial highlights for each of the three years then ended and for the period October 15, 2014 (commencement of operations) through October 31, 2014, in conformity with accounting principles generally accepted in the United States of America. These consolidated financial statements and consolidated financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, transfer agent and brokers, or by other appropriate auditing procedures where replies were not received, provide a reasonable basis for our opinion.

Board Review and Approval of Investment Advisory

Contract

iSHARES^® COMMODITIES SELECT STRATEGY ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”), and the Sub-Advisory Agreement between BFA and BlackRock International Limited (“BIL”) (the “Sub-Advisory Agreement”), on behalf of the Fund. The Advisory Contract and the Sub-Advisory Agreement are referred to hereafter as the “Advisory Agreements”. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Agreements. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on May 5, 2017 and May 12, 2017. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 18, 2017, management presented information to the Board relating to the continuance of the Advisory Agreements, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 19-21, 2017, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Agreements for the Fund, based on a review of qualitative and quantitative information provided by BFA. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential further enhancements to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Agreements for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (“ETFs”) (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of the proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were lower than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board also noted that BFA pays BIL for its sub-advisory services, and that there are no additional fees imposed on the Fund in respect of the services provided under the Sub-Advisory Agreement.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the quarter ended December 31, 2016, to that of relevant comparison funds for the same periods.

BOARD REVIEWAND APPROVALOF INVESTMENT ADVISORY CONTRACT 31

Board Review and Approval of Investment Advisory

Contract (Continued)

iSHARES^® COMMODITIES SELECT STRATEGY ETF

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in comparison with its benchmark index. Such periodic comparative performance information, including any additional detailed information requested by the Boards, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s strategy and benchmark index.

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

Nature, Extent and Quality of Services Provided by BFA and BIL or their Affiliates — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, technology, product design, compliance and risk management, and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA (and any services provided by BIL on BFA’s behalf or at BFA’s direction) under the Advisory Agreements for the coming year as compared to the scope of services provided by BFA and BIL during prior years. In reviewing the scope of these services, the Board considered the investment philosophy and experience of BFA and BIL, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered the compliance program of BFA and BIL and their compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 19-21, 2017 meeting and throughout the previous year, and matters related to BFA’s and BIL’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

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

Costs of Services Provided to Fund and Profits Realized by BFA and Affiliates — The Board reviewed information about the profitability of the Fund to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, including supplemental information that was responsive to requests of the 15(c) Committee. The Board noted that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BFA affiliate, from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

iSHARES^® COMMODITIES SELECT STRATEGY ETF

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on by the 15(c) Committee during its meetings and addressed by management, including through supplemental information. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints and waivers or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale be identified in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider the Advisory Agreements at least annually, determined to approve the continuance of the Advisory Agreements for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded ETF, as compared to the Other Accounts that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged BFA’s expressed business purpose for launching a suite of iShares “Core” ETFs that generally are subject to lower investment advisory fees than iShares non-Core ETFs that may provide a similar investment exposure. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement

that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Agreements for the coming year.

Conclusion — Based on the considerations described above, the Board determined that the Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded to approve the continuance of the Advisory Agreements for the coming year.

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

Item 2. Code of Ethics.

The registrant has adopted a code of ethics, as of the end of the period covered by this report, applicable to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. During the period covered by this report, the code of ethics was amended to clarify an inconsistency in to whom persons covered by the code should report suspected violations of the code.

The registrant undertakes to provide a copy of the code of ethics to any person upon request, without charge, by calling 1-800-474-2737.

Item 3. Audit Committee Financial Expert.

The registrant’s Board of Trustees has determined that the registrant has more than one audit committee financial expert, as that term is defined under Item 3(b) and 3(c), serving on its audit committee. The audit committee financial experts serving on the registrant’s audit committee are Charles A. Hurty, Richard L. Fagnani (began

serving on the audit committee effective as of June 20, 2017 and was designated as an audit committee financial expert serving on the audit committee effective as of September 15, 2017), John E. Kerrigan, and Madhav V. Rajan, all of whom are independent, as that term is defined under Item 3(a)(2).

Item 4. Principal Accountant Fees and Services.

The principal accountant fees disclosed in items 4(a), 4(b), 4(c), 4(d) and 4(g) are for the nine series of the registrant for which the fiscal year-end is October 31, 2017 (the “Funds”), and whose annual financial statements are reported in Item 1.

(a) Audit Fees – The aggregate fees billed for each of the last two fiscal years for professional services rendered by the principal accountant for the audit of the Funds’ annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for those fiscal years were $121,700 for the fiscal year ended October 31, 2016 and $119,550 for the fiscal year ended October 31, 2017.

(b) Audit-Related Fees – There were no fees billed for the fiscal years ended October 31, 2016 and October 31, 2017 for assurance and related services by the principal accountant that were reasonably related to the performance of the audit of the Fund’s financial statements and are not reported under (a) of this Item.

(c) Tax Fees – The aggregate fees billed in each of the last two fiscal years for professional services rendered by the principal accountant for tax compliance, tax advice and tax planning for the Funds were $34,029 for the fiscal year ended October 31, 2016 and $34,029 for the fiscal year ended October 31, 2017. These services related to the review of the Funds’ tax returns and excise tax calculations.

(d) All Other Fees – There were no other fees billed in each of the fiscal years ended October 31, 2016 and October 31, 2017 for products and services provided by the principal accountant, other than the services reported in (a) through (c) of this Item.

(e) (1) The registrant’s audit committee charter, as amended, provides that the audit committee is responsible for the approval, prior to appointment, of the engagement of the principal accountant to annually audit and provide their opinion on the registrant’s financial statements. The audit committee must also approve, prior to appointment, the engagement of the principal accountant to provide non-audit services to the registrant or to any entity controlling, controlled by or under common control with the registrant’s investment adviser (“Adviser Affiliate”) that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant.

(2) There were no services described in (b) through (d) above that were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) None of the hours expended on the principal accountant’s engagement to audit the Funds’ financial statements for the fiscal year ended October 31, 2017 were attributable to work performed by persons other than the principal accountant��s full-time, permanent employees.

(g) The aggregate non-audit fees billed by the registrant’s principal accountant for services rendered to the Funds, and rendered to the registrant’s investment adviser, and any Adviser Affiliate that provides ongoing services to the registrant for the last two fiscal years were $34,029 for the fiscal year ended October 31, 2016 and $34,029 for the fiscal year ended October 31, 2017. The aggregate non-audit fees for the fiscal year ended October 31, 2016 included in this report are different from those included in the previously filed report covering the 12-month period ended October 31, 2016 as this report excludes non-audit fees for services that were rendered to the registrant’s investment adviser or any Adviser Affiliate that provides ongoing services to the registrant but that were not related to the registrant.

(h) The registrant’s audit committee has considered whether the provision of non-audit services rendered to the registrant’s investment adviser and any Adviser Affiliate that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, if any, is compatible with maintaining the principal accountant’s independence, and has determined that the provision of these services, if any, does not compromise the principal accountant’s independence.

(a) The registrant is a listed issuer as defined in Rule 10A-3 under the Exchange Act of 1934 and has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act of 1934.
