MARCH 31, 2021

Dear Shareholder,

The 12-month reporting period as of March 31, 2021 reflected a remarkable period of disruption andadaptation, as the global economy dealt with the implications of the coronavirus (or “COVID-19”)pandemic. As the period began, the response to the virus’s spread was well underway, and countriesaround the world instituted economically disruptive countermeasures. Stay-at-home orders and closuresof non-essential businesses became widespread, many workers were laid off, and unemployment claimsspiked, causing a global recession and a sharp fall in equity prices.

As April 2020 began, stocks were near their lowest point since the beginning of the pandemic. However,a steady recovery began, as businesses started re-opening and governments learned to adapt to life withthe virus. Equity prices continued to rise throughout the summer, fed by strong fiscal and monetarysupport and improving economic indicators. Many equity indices neared or surpassed all-time highs latein the reporting period following the implementation of mass vaccination campaigns and passage of anadditional $1.9 trillion of fiscal stimulus. In the United States, both large- and small-capitalization stocksposted a significant advance. International equities also gained, as both developed countries andemerging markets rebounded substantially.

The 10-year U.S. Treasury yield (which is inversely related to bond prices) was near all-time lows as theperiod began, reflecting a reduced investor appetite for risk. However, inflation concerns from a rapidlyexpanding economy raised yields late in the reporting period, leading to a negative overall return for mostU.S. Treasuries. In the corporate bond market, support from the U.S. Federal Reserve (the “Fed”)assuaged credit concerns and led to positive returns for corporate bonds, particularly high-yield corpo-rates, which gained substantially.

The Fed remained committed to accommodative monetary policy by maintaining near zero interest ratesand by announcing that inflation could exceed its 2% target for a sustained period without triggering a rateincrease. To stabilize credit markets, the Fed also continued purchasing significant quantities of bonds, asdid other influential central banks around the world, including the European Central Bank and the Bank ofJapan.

Looking ahead, while coronavirus-related disruptions have clearly hindered worldwide economic growth,we believe that the global expansion will continue to accelerate as vaccination efforts ramp up andpent-up consumer demand leads to higher spending. In early 2021, President Biden signed one of thelargest economic rescue packages in U.S. history, which should provide a solid tailwind for economicgrowth. In our view, inflation is likely to increase somewhat as the expansion continues, but moderateinflation is less likely to be followed by interest rate hikes that could threaten the economic expansion dueto the change in Fed policy.

Overall, we favor a positive stance toward risk, with an overweight in equities. We see U.S. and Asianequities outside of Japan benefiting from structural growth trends in technology, while emerging marketsshould be particularly helped by a vaccine-led economic expansion. While we are neutral overall oncredit, rising inflation should provide tailwinds for inflation-protected bonds, and global high-yield andAsian bonds also present attractive opportunities. We believe that international diversification and a focuson sustainability can help provide portfolio resilience, and the disruption created by the coronavirusappears to be accelerating the shift toward sustainable investments.

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

Domestic Market Overview

U.S. stocks advanced for the 12 months ended March 31, 2021 (“reporting period”), when the Russell 3000� Index, a broad measure of U.S. equity market performance,returned 62.53%. The reporting period began near the height of uncertainty surrounding the coronavirus pandemic, which drove equity prices to a multi-year low. However,stocks began to recover as the federal government took measures to adapt to the economic and public health impact of the novel coronavirus. Optimism about the growthoutlook for the economy led to further advances, and stocks moved past pre-pandemic prices to reach all-time highs near the end of the reporting period.

The pandemic’s initial economic consequences were swift and far-reaching. Restrictions imposed to slow the virus’ spread resulted in extensive job losses, and theunemployment rate rose quickly, reaching 14.8% in April 2020. Consumer spending, an important engine of economic growth, decreased sharply as people spent more timeat home. These disruptions led to a substantial economic contraction. The U.S. economy declined by an annualized 31.4% in the second quarter of 2020, the largest declineon record.

However, unprecedented fiscal stimulus began to reverse the downward economic momentum. Individuals began to receive direct payments in April 2020 as part of the U.S.$2.2 trillion CARES Act, and payments to support businesses that kept employees on payroll helped to stabilize the economy. Unemployment began to decline, decreasingeach month between April 2020 and November 2020, while still remaining elevated compared to pre-pandemic levels. Equity prices rose in response to the improvingeconomic outlook.

The U.S. Federal Reserve (“Fed”) also responded to the pandemic, maintaining short-term interest rates near zero to encourage lending and stimulate economic activity.The Fed further acted to stabilize bond markets by continuing an unlimited, open-ended, bond buying program for U.S. Treasuries and mortgage-backed securities. TheFed later widened its program to include directly purchasing corporate bonds for the first time, including high-yield bonds. In August 2020, the Fed revised its long-standinginflation policy, allowing inflation to exceed the 2% target to stimulate the economy.

Fiscal and monetary stimulus, along with partial reopenings in many states, helped the economy rebound sharply in the second half of 2020. Economic growth picked upin the third quarter of 2020, with an annualized gain of 33.4%, as some previously shut-down parts of the economy resumed functioning. Growth moderated in the fourthquarter of 2020, rising by an annualized 4.3%.

In addition to the growing economy, stocks were boosted by the November 2020 news that several vaccines under development showed high effectiveness rates. Stocksalso benefited from the results of the election in November 2020, which led to a change of administrations but made wide-reaching reforms less likely due to slim majoritiesin the U.S. Congress. Additional stimulus packages signed in December 2020 and March 2021 propelled further strong gains in equities, and many U.S. stock indexestouched all-time highs near the end of the reporting period.

Rising household wealth amid higher asset prices and the return to economic growth led analysts to expect that high savings and pent-up consumer demand will driveincreased spending as the pandemic wanes. However, this also raised investors’ inflation expectations near the end of the reporting period. Additionally, the unequal natureof the recovery highlighted the difficulty many individuals still face, as total unemployment remained well below pre-pandemic levels, and 30% of Americans reported lowerincomes as of February 2021.

Portfolio Management Commentary

Large-capitalization U.S. stocks advanced strongly for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout of COVID-19vaccination programs drove a robust rebound in economic activity. The information technology sector was the leading contributor to the Index’s return as the coronaviruspandemic disrupted normal business practices and limited face-to-face contact, prompting many businesses to improve and expand their technology systems. Combinedwith a rebound in both consumer and business information technology spending, the accelerated adoption of technology products and services led to solid earnings growthfor the sector. With 42% of the U.S. labor force working from home due to pandemic restrictions, demand for cloud computing and business-oriented infrastructure andsecurity software grew rapidly, driving a solid advance in the software and services industry. The technology hardware and equipment industry also contributed to the Index’sreturn, as the transition to remote work and school drove purchases of personal computers and peripherals.

The consumer discretionary sector also contributed to the Index’s return, rebounding strongly as fiscal stimulus payments and unemployment insurance supplementssupported increased consumer spending. Retailers, which were particularly pressured by pandemic-related restrictions, recovered to post strong gains amid a massCOVID-19 vaccination program and an improving economy. Internet and direct marketing retailers were boosted by an increase in online shopping amid pandemic-relatedrestrictions.

The communication services sector was another source of strength for the Index’s return, led by the media and entertainment industry. Increased online advertising led torevenue gains in the interactive media and services industry. Consumers spending more time at home made greater use of home entertainment products, such ason-demand films and television, streaming services, and video games.

Portfolio Management Commentary

Growth-oriented large-capitalization U.S. stocks advanced strongly for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout ofCOVID-19 vaccination programs drove a robust rebound in economic activity. The information technology sector was the leading contributor to the Index’s return as thecoronavirus pandemic disrupted normal business practices and limited face-to-face contact, prompting many businesses to improve and expand their technology systems.Combined with a rebound in both consumer and business information technology spending, the accelerated adoption of technology products and services led to solidearnings growth for the sector. With 42% of the U.S. labor force working from home due to pandemic restrictions, demand for cloud computing and business-orientedinfrastructure and security software grew rapidly, driving a solid advance in the software and services industry. The technology hardware and equipment industry alsoperformed well, as the transition to remote work and school drove purchases of personal computers and peripherals. The semiconductors and semiconductor equipmentindustry contributed as strong demand led to a semiconductor shortage, boosting revenues for chip makers.

The consumer discretionary sector contributed meaningfully to the Index’s return, rebounding strongly as fiscal stimulus payments and unemployment insurancesupplements supported increased consumer spending. Retailers, which were particularly pressured by pandemic-related restrictions, recovered to post strong gains amidCOVID-19 vaccination programs and an improving economy. Internet and direct marketing retailers benefited from an increase in online shopping amid pandemic-relatedrestrictions.

Portfolio Management Commentary

Value-oriented large-capitalization U.S. stocks advanced strongly for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout ofCOVID-19 vaccination programs drove a robust rebound in economic activity. The financials sector, which is closely tied to the strength of the broader economy, contributedthe most to the Index’s performance. Within the sector, banks were the leading contributors. In the wake of the coronavirus pandemic, bank stocks faced headwinds amidconcerns that widespread business failures would lead to significant loan losses. However, bank stocks rallied when the Fed backed credit markets and effective COVID-19vaccines were developed and distributed, raising investors’ hopes for an economic rebound. Investment banking and brokerage companies also contributed, as highertrading revenues amid a surge in equity trading volume boosted investment banks’ profit margins.

The ongoing economic recovery also helped the economically sensitive industrials sector, which was a solid contributor to the Index’s return. The capital goods industry wasthe primary source of strength amid a rebound in industrial production, although manufacturing output remained below pre-pandemic levels. Strong consumer demand formanufactured goods, including automobiles, helped support U.S. manufacturers.

The healthcare sector contributed to the Index’s performance, as optimism surrounding the economic recovery and the development of new products offset a decline inhealthcare spending, particularly during the early part of the pandemic. Although pandemic-related restrictions led to reduced doctor visits and delayed elective procedures,analysts assessed that deferred demand would lead to increased revenues as the economy rebounded.

The communication services sector was another source of strength for the Index’s return, led by the media and entertainment industry. Consumers spending more time athome made greater use of home entertainment products, such as on-demand films and television, streaming services, and video games.

Portfolio Management Commentary

Value-oriented large- and mid-capitalization U.S. stocks advanced strongly for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rolloutof COVID-19 vaccination programs drove a robust rebound in economic activity. The financials sector, which is closely tied to the strength of the broader economy,contributed the most to the Index’s performance. Within the sector, banks were the leading contributors. In the wake of the coronavirus pandemic, bank stocks facedheadwinds amid concerns that widespread business failures would lead to significant loan losses. However, bank stocks rallied when the Fed backed credit markets andeffective COVID-19 vaccines were developed and distributed, raising investors’ hopes for an economic rebound. Late in the reporting period, higher long-term bond yieldsalso pointed to a strengthening economy, further supporting bank stocks. Investment banking and brokerage companies also contributed, as higher trading revenues amida surge in equity trading volume boosted investment banks’ profit margins.

The ongoing economic recovery also helped the economically sensitive industrials sector, which was a solid contributor to the Index’s return. The capital goods industry wasthe primary source of strength amid a rebound in industrial production, although manufacturing output remained below pre-pandemic levels. Optimism about continuedeconomic growth led to the highest levels of business confidence in more than 35 years. Strong consumer demand for manufactured goods, including automobiles, helpedsupport U.S. manufacturers.

The consumer discretionary sector also contributed to the Index’s return, rebounding strongly after a decline early in the pandemic. Retailers posted strong gains amid amass COVID-19 vaccination program and an improving economy. Consumers increased savings and reduced credit card debt amid the pandemic, which led to a surge inspending on nonessential items, benefiting the specialty retail industry.

Portfolio Management Commentary

Small-capitalization U.S. stocks advanced sharply for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout of COVID-19 vaccinationprograms drove a robust rebound in economic activity. The consumer discretionary sector was the leading contributor to the Index’s return, as fiscal stimulus payments andunemployment insurance supplements helped consumer spending partially recover from a sharp decline in the second quarter of 2020. Retailers, which were particularlypressured by pandemic-related restrictions, recovered to post strong gains amid vaccination programs and an improving economy. Consumers increased savings andreduced credit card debt amid the pandemic, which led to a surge in spending on nonessential items, benefiting the specialty retail industry.

The economically sensitive industrials sector was a solid contributor to the Index’s return. The capital goods industry benefited from a rebound in industrial production,although manufacturing output remained below pre-pandemic levels. Optimism about economic growth led to the highest levels of business confidence in more than 35years. Strong consumer demand for manufactured goods, including automobiles, helped support U.S. manufacturers.

The healthcare sector was a significant contributor to the Index’s performance, supported by optimism surrounding the economic recovery and the development of newproducts. Pandemic-related restrictions led patients to make fewer doctor visits and delay elective procedures. However, analysts assessed that deferred demand for healthservices would lead to increased revenues as the economy continued to rebound. Additionally, U.S. election results suggest sector disruption from legislative changes isunlikely.

The financials sector also contributed to the Index’s performance. Bank stocks rallied when the Fed backed credit markets and effective COVID-19 vaccines weredeveloped and distributed, raising expectations for an economic rebound. Late in the reporting period, higher long-term bond yields also pointed to a strengtheningeconomy, further supporting bank stocks.

Portfolio Management Commentary

Growth-oriented, small-capitalization U.S. stocks advanced sharply for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout ofCOVID-19 vaccination programs drove a robust rebound in economic activity. The healthcare sector was the leading contributor to the Index’s performance, as optimismsurrounding the economic recovery and the development of new products offset a decline in healthcare spending. Pandemic-related restrictions led patients to make fewerdoctor visits and delay elective procedures. However, analysts assessed that deferred demand for health services would lead to increased revenues as the economycontinued to rebound. The biotechnology industry led contributions, gaining amid increased adoption of advanced prenatal screening and oncology tests as well aspromising developments in cell therapeutic treatments. The healthcare equipment and services industry also advanced, helped by new antigen-based COVID-19 tests anda rebound in demand for equipment to treat sleep apnea.

The information technology sector was another source of strength for the Index’s return. Combined with a rebound in both consumer and business information technologyspending, the accelerated adoption of technology products and services led to solid earnings growth for the sector. With 42% of the U.S. labor force working from home,demand for cloud computing and business-oriented infrastructure and security software grew rapidly, supporting a solid advance in the software and services industry.

The consumer discretionary sector was also a notable contributor, rebounding strongly as fiscal stimulus payments and unemployment insurance supplements supportedincreased consumer spending. The consumer services industry, which includes casinos and gaming stocks, gained as bookings at resorts and casino operators rose amidcapacity increases. Online gaming, particularly sports betting, also increased, further bolstering the industry.

Portfolio Management Commentary

Value-oriented small-capitalization U.S. stocks advanced sharply for the reporting period, as unprecedented monetary and fiscal stimulus coupled with the rollout ofCOVID-19 vaccination programs drove a robust rebound in economic activity. The financials sector, which is closely tied to the strength of the broader economy, contributedthe most to the Index’s performance. Within the sector, banks were the leading contributors. In the wake of the coronavirus pandemic, bank stocks faced headwinds amidconcerns that widespread business failures would lead to significant loan losses. However, bank stocks rallied when the Fed backed credit markets and effective COVID-19vaccines were developed and distributed, raising investors’ hopes for an economic rebound. Late in the reporting period, higher long-term bond yields also pointed to astrengthening economy, further supporting bank stocks.

The consumer discretionary sector also contributed significantly to the Index’s return, rebounding strongly after a decline early in the pandemic. Retailers, which wereparticularly pressured by the onset of the pandemic and related restrictions, posted strong gains amid a mass COVID-19 vaccination program and an improving economy.Consumers increased savings and reduced credit card debt amid the pandemic, which led to a surge in spending on nonessential items, benefiting the specialty retailindustry. Similarly, hotels, restaurants, and leisure stocks contributed, as hotel and cruise bookings increased amid optimism about vaccinations.

The ongoing economic recovery also helped the economically sensitive industrials sector, which was a solid contributor to the Index’s return. The capital goods industry wasthe primary source of strength amid a rebound in industrial production, although manufacturing output remained below pre-pandemic levels. Optimism about continuedeconomic growth led to the highest levels of business confidence in more than 35 years. Strong consumer demand for manufactured goods, including automobiles, helpedsupport U.S. manufacturers.

Past performance is not an indication of future results. Financial markets have experienced extreme volatility and trading in many instruments has been disrupted. Thesecircumstances may continue for an extended period of time and may continue to affect adversely the value and liquidity of the fund's investments. As a result, currentperformance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at iShares.com. Performanceresults 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 oron 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 orless than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees.Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. Beginning August 10,2020, the price used to calculate market return ("Market Price") is the closing price. Prior to August 10, 2020, Market Price was determined by using the midpoint betweenthe highest bid and the lowest ask on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Marketand 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 doesnot incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may bepayable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

Shareholder Expenses

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

Actual Expenses – The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary feewaivers, 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 valuedivided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period.”

Hypothetical Example for Comparison Purposes – The table also provides information about hypothetical account values and hypothetical expenses based on yourFund’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 yourFund 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 commissionsand other fees paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing costs only and will not help you determinethe relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

2. SIGNIFICANT ACCOUNTING POLICIES

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

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed.Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, arerecorded on the ex-dividend date. Non-cash dividends, if any, are recorded on the ex-dividend date at fair value. Dividends from foreign securities where the ex-dividenddate may have passed are subsequently recorded when the Funds are informed of the ex-dividend date. Under the applicable foreign tax laws, a withholding tax at variousrates may be imposed on capital gains, dividends and interest. Upon notification from issuers or as estimated by management, a portion of the dividend income receivedfrom a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization andaccretion of premiums and discounts on debt securities, is recognized daily on an accrual basis.

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 certainforeign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in whicheach Fund invests. These foreign taxes, if any, are paid by each Fund and are reflected in its statement of operations as follows: foreign taxes withheld at source arepresented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividendsare 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 theirrespective net realized gain (loss) categories. Foreign taxes payable or deferred as of March 31, 2021, if any, are disclosed in the statement of assets and liabilities.

The Funds file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. The Funds may record a reclaim receivable based oncollectability, which includes factors such as the jurisdiction’s applicable laws, payment history and market convention. The statement of operations includes tax reclaimsrecorded as well as professional and other fees, if any, associated with recovery of foreign withholding taxes.

Segregation and Collateralization: In cases where a Fund enters into certain investments (e.g., futures contracts ) that would be treated as “senior securities” for 1940Act purposes, a Fund may segregate or designate on its books and record cash or liquid assets having a market value at least equal to the amount of its future obligationsunder such investments. Doing so allows the investment to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterpartyagreement, the Funds may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments orobligations.

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

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

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

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

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

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:• Equity investments traded on a recognized securities exchange are valued at that day’s 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.• Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s published NAV.• Futures contracts are valued based on that day’s last reported settlement or trade price on the exchange where the contract is traded.

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

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

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

• Level 1 – Unadjusted price quotations in active markets/exchanges for identical assets or liabilities that each Fund has the ability to access;• Level 2 – Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or

similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yieldcurves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs); and

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

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

4. SECURITIES AND OTHER INVESTMENTS

Warrants: Warrants entitle a fund to purchase a specified number of shares of common stock and are non-income producing. The purchase price and number of sharesare subject to adjustment under certain conditions until the expiration date of the warrants, if any. If the price of the underlying stock does not rise above the strike price beforethe warrant expires, the warrant generally expires without any value and a fund will lose any amount it paid for the warrant. Thus, investments in warrants may involve morerisk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move withthe price of the underlying stock.

Short Positions: From time to time, in order to track the performance of its benchmark index, a fund may sell non-index securities that will be received through corporateactions occurring on the opening of market trading on the following business day. A fund may also experience temporary short positions due to the timing of portfoliosecurities trades and in-kind redemption transactions. Such short positions are valued consistent with how securities are valued as described under Investment Valuation

and Fair Value Measurements. The obligation to deliver the securities is recorded as a liability in the statement of assets and liabilities and is equal to the current fair valueof the securities to be delivered. Any market fluctuations between the value of the obligation to sell these securities and the current fair value are reflected as unrealizedappreciation (depreciation) in the statement of operations. Upon receipt of the securities related to the corporate actions or purchase of the securities related to the shortposition, a realized gain (loss) is recorded. Dividends or interest on securities sold short, if any, are reflected as an expense in the statement of operations. Details of theshort positions, if any, are included in the schedule of investments.

Securities Lending: Each Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges andmaintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by an approved bank, or securities issued or guaranteed by the U.S. government.The initial collateral received by each Fund is required to have a value of at least 102% of the current market value of the loaned securities for securities traded on U.S.exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securitieson loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fundor excess collateral is returned by the Fund, on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loanedsecurities 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 requiredto return borrowed securities within the standard time period for settlement of securities transactions.

As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested in money market funds managed byBlackRock Fund Advisors (“BFA”), the Funds' investment adviser, or its affiliates is disclosed in the schedules of investments. Any non-cash collateral received cannot besold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan, if any, are also disclosed in each Fund's schedule of investments.The market value of any securities on loan and the value of any related cash collateral are disclosed in the statements of assets and liabilities.

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

As of period end, the following table is a summary of the securities on loan by counterparty which are subject to offset under an MSLA as of March 31, 2021:

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

(b) Additional collateral is delivered to the Fund on the next business day in accordance with the MSLA. The net amount would be subject to the borrower default indemnity in the eventof default by a counterparty.

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 mitigatethese risks, each Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of thesecurities loaned to the extent the collateral received does not cover the value of the securities loaned in the event of borrower default. Each Fund could incur a loss if thevalue of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateralfalls below the value of the original cash collateral received. Such losses are borne entirely by each Fund.

5. DERIVATIVE FINANCIAL INSTRUMENTS

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

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

Securities deposited as initial margin are designated in the schedule of investments and cash deposited, if any, are shown as cash pledged for futures contracts in thestatement of assets and liabilities. Pursuant to the contract, the Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in marketvalue of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation margin receivable (orpayable) on futures contracts in the statement of assets and liabilities. When the contract is closed, a realized gain or loss is recorded in the statement of operations equalto the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. The use of futures contractsinvolves the risk of an imperfect correlation in the movements in the price of futures contracts and interest rates, foreign currency exchange rates or underlying assets.

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

Securities Lending: The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company,N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operationalcosts directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan (the“collateral investment fees”). The cash collateral is invested in a money market fund, BlackRock Cash Funds: Institutional or BlackRock Cash Funds: Treasury, managedby BFA, or its affiliates. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment feeseach Fund bears to an annual rate of 0.04%. The SL Agency Shares of such money market fund will not be subject to a sales load, distribution fee or service fee. The moneymarket fund in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value redeemed or temporarily restrictredemptions for up to 10 business days during a 90 day period, in the event that the money market fund’s weekly liquid assets fall below certain thresholds.

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

Pursuant to the current securities lending agreement, each Fund retains 77% of securities lending income (which excludes collateral investment fees) and the amountretained 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 ActiShares exchange-traded funds (the “iShares ETF Complex”) in that calendar year exceeds a specified threshold, each Fund, pursuant to the securities lending agreement,will retain for the remainder of that calendar year 81% of securities lending income (which excludes collateral investment fees), and the amount retained can never be lessthan 70% of the total of securities lending income plus the collateral investment fees.

Prior to January 1, 2021, each Fund retained 75% of securities lending income (which excludes collateral investment fees) and the amount retained was not 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 lendingincome plus the collateral investment fees generated across the iShares ETF Complex in a calendar year exceeded a specified threshold, each Fund, pursuant to thesecurities lending agreement, retained for the remainder of that calendar year 80% of securities lending income (which excludes collateral investment fees), and the amountretained could never be less than 70% of the total of securities lending income plus the collateral investment fees.

8. INCOME TAX INFORMATION

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

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

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications haveno effect on net assets or NAV per share. As of March 31, 2021, the following permanent differences attributable to distributions paid in excess of taxable income andrealized gains (losses) from in-kind redemptions were reclassified to the following accounts:

(a) Amounts available to offset future realized capital gains.(b) The difference between book-basis and tax-basis unrealized gains (losses) was attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of

unrealized gains (losses) on certain futures contracts, the realization for tax purposes of unrealized gains on investments in passive foreign investment companies, the timing andrecognition of partnership income and the characterization of corporate actions.

A fund may own shares in certain foreign investment entities, referred to, under U.S. tax law, as “passive foreign investment companies.” Such fund may elect tomark-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.

9. 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 variousrisks, 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 mayalso 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 socialinstability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. Local, regional or global eventssuch as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Funds andtheir investments. Each 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 each Fund’s investment objective following the securities included in its underlying index during upturns as wellas 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 compositionof the portfolio is monitored by BFA.

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

Market Risk: An outbreak of respiratory disease caused by a novel coronavirus has developed into a global pandemic and has resulted in closing borders, quarantines,disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other global health crises that may arisein the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time.

This pandemic may result in substantial market volatility and may adversely impact the prices and liquidity of a fund's investments. The duration of this pandemic and itseffects cannot be determined with certainty.

Valuation Risk: The market values of equities, such as common stocks and preferred securities or equity related investments, such as futures and options, may declinedue to general market conditions which are not specifically related to a particular company. They may also decline due to factors which affect a particular industry orindustries. A fund may invest in illiquid investments. An illiquid investment is any investment that a fund reasonably expects cannot be sold or disposed of in current marketconditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. A fund may experience difficulty in sellingilliquid investments in a timely manner at the price that it believes the investments are worth. Prices may fluctuate widely over short or extended periods in response tocompany, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. This volatility may cause a fund’s NAV to experiencesignificant increases or decreases over short periods of time. If there is a general decline in the securities and other markets, the NAV of a fund may lose value, regardlessof the individual results of the securities and other instruments in which a fund invests.

The price each Fund could receive upon the sale of any particular portfolio investment may differ from each Fund’s valuation of the investment, particularly for securitiesthat trade in thin or volatile markets or that are valued using a fair valuation technique or a price provided by an independent pricing service. Changes to significantunobservable inputs and assumptions (i.e., publicly traded company multiples, growth rate, time to exit) due to the lack of observable inputs.

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

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

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

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

Certain Funds invest a significant portion of their assets in securities within a single or limited number of market sectors. When a Fund concentrates its investments in thismanner, it assumes the risk that economic, regulatory, political and social conditions affecting such sectors may have a significant impact on the fund and could affect theincome from, or the value or liquidity of, the fund’s portfolio. Investment percentages in specific sectors are presented in the schedule of investments.

LIBOR Transition Risk: The United Kingdom’s Financial Conduct Authority announced a phase out of the London Interbank Offered Rate (“LIBOR”). Although many LIBORrates will be phased out by the end of 2021, a selection of widely used USD LIBOR rates will continue to be published through June 2023 in order to assist with the transition.The Funds may be exposed to financial instruments tied to LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The transitionprocess away from LIBOR might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whoseterms currently include LIBOR. The ultimate effect of the LIBOR transition process on the Funds is uncertain.

10. CAPITAL SHARE TRANSACTIONS

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 specifiedamount 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 Unitsmay 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 othertransaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may alsopay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, andbrokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in shares sold in the table above.

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind transactionsare reflected as a receivable or a payable in the statement of assets and liabilities.

11. LEGAL PROCEEDINGS

Certain iShares funds (the “Impacted Funds”), along with thousands of other former shareholders of Tribune Company (“Tribune”), were named as defendants in one ormore lawsuits (the “Litigation”) arising out of Tribune's 2007 leveraged buyout transaction ("LBO"). The Litigation seeks to “claw back” from former Tribune shareholders,including the Impacted Funds, proceeds received in connection with the LBO. The iShares Russell 1000 ETF and iShares Russell 1000 Value ETF received proceeds of$750,618 and $4,187,372, respectively, in the LBO. The claims that were originally brought against the Impacted Funds were dismissed but are currently subject to anappeal which remains pending. The outcome of this appeal could result in new claims being brought against the Impacted Funds and/or previously dismissed claims beingrevived and subject to continuing litigation. The Impacted Funds intend to vigorously defend the Litigation.

In compliance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the “Liquidity Rule”), iShares Trust (the “Trust”) has adopted and implemented aliquidity risk management program (the “Program”) for iShares Russell Top 200 ETF, iShares Russell Top 200 Growth ETF, iShares Russell Top 200 Value ETF, iSharesRussell 1000 ETF, iShares Russell 1000 Growth ETF, iShares Russell 1000 Value ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF and iShares Russell2000 Value ETF (the “Funds” or “ETFs”), each a series of the Trust, which is reasonably designed to assess and manage each Fund’s liquidity risk.

The Board of Trustees (the “Board”) of the Trust, on behalf of the Funds, met on December 2, 2020 (the “Meeting”) to review the Program. The Board previously appointedBlackRock Fund Advisors (“BlackRock”), the investment adviser to the Funds, as the program administrator for each Fund’s Program. BlackRock also previously delegatedoversight of the Program to the 40 Act Liquidity Risk Management Committee (the “Committee”). At the Meeting, the Committee, on behalf of BlackRock, provided the Boardwith a report that addressed the operation of the Program and assessed its adequacy and effectiveness of implementation, including the management of each Fund’s HighlyLiquid Investment Minimum (“HLIM”) where applicable, and any material changes to the Program (the “Report”). The Report covered the period from October 1, 2019through September 30, 2020 (the “Program Reporting Period”).

The Report described the Program’s liquidity classification methodology for categorizing a Fund’s investments (including derivative transactions) into one of four liquiditybuckets. It also referenced the methodology used by BlackRock to establish a Fund’s HLIM and noted that the Committee reviews and ratifies the HLIM assigned to eachFund no less frequently than annually. The Report also discussed notable events affecting liquidity over the Program Reporting Period, including extended market holidaysand closures in certain countries and the impact of the coronavirus outbreak on the Funds and the overall market.

The Report noted that the Program complied with the key factors for consideration under the Liquidity Rule for assessing, managing and periodically reviewing a Fund’sliquidity risk, as follows:

a) The Fund’s investment strategy and liquidity of portfolio investments during both normal and reasonably foreseeable stressed conditions. During theProgram Reporting Period, the Committee reviewed whether each Fund’s strategy is appropriate for an open-end fund structure, with a focus on Funds with moresignificant and consistent holdings of less liquid and illiquid assets. The Committee factored a Fund’s concentration in an issuer into the liquidity classificationmethodology by taking issuer position sizes into account. Derivative exposure was also considered in the calculation of a Fund’s liquidity bucketing. Finally, a factorfor consideration under the Liquidity Rule is a Fund’s use of borrowings for investment purposes. However, the Funds do not borrow for investment purposes.

b) Short-term and long-term cash flow projections during both normal and reasonably foreseeable stressed conditions. During the Program Reporting Period,the Committee reviewed historical redemption activity and used this information as a component to establish each ETF’s reasonably anticipated trading size (“RATS”).The Committee may also take into consideration a Fund’s shareholder ownership concentration (which, depending on product type and distribution channel, may ormay not be available), a Fund’s distribution channels, and the degree of certainty associated with a Fund’s short-term and long-term cash flow projections.

c) Holdings of cash and cash equivalents, as well as borrowing arrangements. The Committee considered that ETFs generally do not hold more than de minimisamounts of cash. While the ETFs generally do not engage in borrowing, certain of the ETFs have the flexibility to draw on a line of credit to meet redemption requestsor facilitate settlements.

d) The relationship between an ETF’s portfolio liquidity and the way in which, and the prices and spreads at which, ETF shares trade, including the efficiencyof the arbitrage function and the level of active participation by market participants, including authorized participants. The Committee monitored theprevailing bid/ask spread and the ETF price premium (or discount) to NAV for all ETFs and reviewed any persistent deviations from long-term averages.

e) The effect of the composition of baskets on the overall liquidity of an ETF’s portfolio. In reviewing the linkage between the composition of custom basketsaccepted by an ETF and any significant change in the liquidity profile of such ETF, the Committee reviewed changes in the proportion of each ETF’s portfolio comprisedof less liquid and illiquid holdings to determine if applicable thresholds were met requiring enhanced review.

As part of BlackRock’s continuous review of the effectiveness of the Program, the Committee made the following enhancements to the Program: (1) certain single countryemerging market ETFs were added to a $300 million credit agreement with State Street Bank and Trust Company; and (2) certain updates were made to the RATS and HLIMcalculation methodology. The Report provided to the Board stated that the Committee concluded that based on the operation of the functions, as described in the Report,the Program is operating as intended and is effective in implementing the requirements of the Liquidity Rule.

Regulation Regarding Derivatives

On October 28, 2020, the Securities and Exchange Commission (the “SEC”) adopted new regulations governing the use of derivatives by registered investment companies(“Rule 18f-4”). The Funds will be required to implement and comply with Rule 18f-4 by August 19, 2022. Once implemented, Rule 18f-4 will impose limits on the amount ofderivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as seniorsecurities and require funds whose use of derivatives is more than a limited specified exposure amount to establish and maintain a comprehensive derivatives riskmanagement program and appoint a derivatives risk manager.

Section 19(a) Notices

The amounts and sources of distributions reported are estimates and are being provided pursuant to regulatory requirements and are not being provided for tax reportingpurposes. The actual amounts and sources for tax reporting purposes will depend upon each Fund's investment experience during the year and may be subject to changesbased on tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income taxpurposes.

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

(b) Rounds to less than 1%.

Premium/Discount Information

Information on the Fund's net asset value, market price, premiums and discounts, and bid-ask spreads can be found at iShares.com.

Regulation under the Alternative Investment Fund Managers Directive

The Alternative Investment Fund Managers Directive (the “Directive”) imposes detailed and prescriptive obligations on fund managers established in the European Union(the “EU”). These do not currently apply to managers established outside of the EU, such as BFA (the “Company”). Rather, non-EU managers are only required to complywith certain disclosure, reporting and transparency obligations of the Directive if such managers market a fund to EU investors.

The Company has registered the iShares Russell 1000 Value ETF and iShares Russell 2000 ETF (each a “Fund”, collectively the "Funds") to be marketed to EU investorsin the United Kingdom, the Netherlands, Finland, Sweden, and Luxembourg.

Report on Remuneration

The Company is required under the Directive to make quantitative disclosures of remuneration. These disclosures are made in line with BlackRock’s interpretation ofcurrently available regulatory guidance on quantitative remuneration disclosures. As market or regulatory practice develops BlackRock may consider it appropriate to makechanges to the way in which quantitative remuneration disclosures are calculated. Where such changes are made, this may result in disclosures in relation to a fund notbeing comparable to the disclosures made in the prior year, or in relation to other BlackRock fund disclosures in that same year.

Disclosures are provided in relation to (a) the staff of the Company; (b) staff who are senior management; and (c) staff who have the ability to materially affect the risk profileof the Funds.

All individuals included in the aggregated figures disclosed are rewarded in line with BlackRock’s remuneration policy for their responsibilities across the relevant BlackRockbusiness area. As all individuals have a number of areas of responsibilities, only the portion of remuneration for those individuals’ services attributable to the Funds isincluded in the aggregate figures disclosed.

BlackRock has a clear and well defined pay-for-performance philosophy, and compensation programmes which support that philosophy.

BlackRock operates a total compensation model for remuneration which includes a base salary, which is contractual, and a discretionary bonus scheme. Although allemployees are eligible to receive a discretionary bonus, there is no contractual obligation to make a discretionary bonus award to any employees. For senior management,a significant percentage of variable remuneration is deferred over time. All employees are subject to a claw-back policy.

Remuneration decisions for employees are made once annually in January following the end of the performance year, based on BlackRock’s full-year financial results andother non-financial goals and objectives. Alongside financial performance, individual total compensation is also based on strategic and operating results and otherconsiderations such as management and leadership capabilities. No set formulas are established and no fixed benchmarks are used in determining annual incentiveawards.

Annual incentive awards are paid from a bonus pool which is reviewed throughout the year by BlackRock's independent compensation committee, taking into account bothactual and projected financial information together with information provided by the Enterprise Risk and Regulatory Compliance departments in relation to any activities,incidents or events that warrant consideration in making compensation decisions. Individuals are not involved in setting their own remuneration.

Each of the control functions (Enterprise Risk, Legal & Compliance, and Internal Audit) each have their own organisational structures which are independent of the businessunits. Functional bonus pools for those control functions are determined with reference to the performance of each individual function and the remuneration of the seniormembers of control functions is directly overseen by BlackRock's independent remuneration committee.

Members of staff and senior management of the Company typically provide both AIFMD and non-AIFMD related services in respect of multiple funds, clients and functionsof the Company and across the broader BlackRock group. Therefore, the figures disclosed are a sum of each individual’s portion of remuneration attributable to the Fundsaccording to an objective apportionment methodology which acknowledges the multiple-service nature of the Company. Accordingly the figures are not representative ofany individual’s actual remuneration or their remuneration structure.

The amount of the total remuneration awarded by the Company to its staff which has been attributed to the iShares Russell 1000 Value ETF in respect of the Company’sfinancial year ending 31 December 2020 is USD 3.41 million. This figure is comprised of fixed remuneration of USD 1.59 million and variable remuneration of USD1.82 million. There were a total of 490 beneficiaries of the remuneration described above.

The amount of the aggregate remuneration awarded by the Company, which has been attributed to the iShares Russell 1000 Value ETF in respect of the Company’sfinancial year ending 31 December 2020, to its senior management was USD 555.76 thousand, and to members of its staff whose actions have a material impact on therisk profile of the Fund was USD 44.86 thousand.

The amount of the total remuneration awarded by the Company to its staff which has been attributed to the iShares Russell 2000 ETF in respect of the Company’s financialyear ending 31 December 2020 is USD 4.55 million. This figure is comprised of fixed remuneration of USD 2.12 million and variable remuneration of USD 2.43 million. Therewere a total of 490 beneficiaries of the remuneration described above.

The amount of the aggregate remuneration awarded by the Company, which has been attributed to the iShares Russell 2000 ETF in respect of the Company’s financial yearending 31 December 2020, to its senior management was USD 741.54 thousand, and to members of its staff whose actions have a material impact on the risk profile of theFund was USD 59.86 thousand.
