iSHARES^®CORE INTERNATIONAL AGGREGATE BOND ETF

Ticker: IAGG

Stock Exchange: Cboe BZX

Investment Objective

The iShares Core International Aggregate Bond ETF (the “Fund”) seeks to track the investment results of an index composed of global non-U.S. dollar-denominated investment-grade bonds that mitigates exposure to fluctuations between the value of the component currencies and the U.S. dollar.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses.

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

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)¹
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses²	Total Annual Fund Operating Expenses
0.07%	None	0.00%	0.07%

¹	The expense information in the table has been restated to reflect current fees.

²The amount rounded to 0.00%.

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

1 Year		3 Years		5 Years		10 Years
$7		$23		$40		$90

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 11% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the Bloomberg Global Aggregate ex USD 10% Issuer Capped (Hedged) Index (the “Underlying Index”), which measures the performance of the global investment-grade (as determined by Bloomberg Index Services Limited (the “Index Provider” or “Bloomberg”)) bond market. As of October 31, 2022, there were 12,395 issues in the Underlying Index. The Underlying Index includes investment-grade fixed-rate sovereign and government-related debt, corporate and securitized bonds from both developed and emerging market issuers. Securities included in the Underlying Index are issued in currencies other than the U.S. dollar, must have maturities of at least one year and are required to meet minimum outstanding issue size criteria. The Underlying Index is market capitalization-weighted with a cap on each issuer of 10%. Debt that is publicly issued in the global and regional markets is included in the Underlying Index. Certain types of securities, such as USD-denominated bonds, contingent

capital securities, inflation-linked bonds, floating-rate issues, fixed-rate perpetuals, retail bonds, structured notes, pass-through certificates, private placements (other than those offered pursuant to Rule 144A or Regulation S promulgated under the Securities Act of 1933, as amended (the “1933 Act”)) and securities where reliable pricing is unavailable are excluded from the Underlying Index. The securities in the Underlying Index are updated on the last business day of each month, and the currency risk of the securities in the Underlying Index are hedged to the U.S. dollar on a monthly basis. As of October 31, 2022, a significant portion of the Underlying Index is represented by non-U.S. government-related bonds. The components of the Underlying Index are likely to change over time.

The Underlying Index was comprised of securities issued by governments in 61 countries or regions as well as securities issued or guaranteed by supranational entities as of October 31, 2022.

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

Table of Contents

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

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

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

The Fund will invest at least 80% of its assets in the component securities of the Underlying Index, and the Fund will invest at least 90% of its assets in fixed income securities of the types included in the Underlying Index that BFA

believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the Fund track the Underlying Index as well as in fixed income securities other than the types included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. Components of the Underlying Index include fixed-income securities and foreign currency forward contracts (both deliverable and non-deliverable) designed to hedge non-U.S. currency fluctuations against the U.S. dollar. The notional exposure to foreign currency forward contracts (both deliverable and non-deliverable) generally will be a short position that hedges the currency risk of the fixed-income portfolio. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Underlying Index sells forward the total value of the underlying non-U.S. dollar currencies at a one-month forward rate to hedge against fluctuations in the relative value of the non-U.S. dollar component currencies in relation to the U.S. dollar. The hedge is reset on a monthly basis. The Underlying Index is designed to have higher returns than an equivalent unhedged investment when the non-U.S. dollar component currencies are weakening relative to the U.S. dollar and appreciation in some of the non-U.S. dollar component currencies does not exceed the aggregate depreciation

S-3

Table of Contents

of the others. Conversely, the Underlying Index is designed to have lower returns than an equivalent unhedged investment when the non-U.S. dollar component currencies, on a net basis, are rising relative to the U.S. dollar.

In order to track the “hedging” component of the Underlying Index, the Fund enters into foreign currency forward contracts designed to offset the Fund’s exposure to the non-U.S. dollar component currencies. A foreign currency forward contract is a contract between two parties to buy or sell a specified amount of a specific currency in the future at an agreed-upon exchange rate. The Fund's exposure to foreign currency forward contracts is based on the aggregate exposure of the Fund to the non-U.S. dollar component currencies. While this approach is designed to minimize the impact of currency fluctuations on Fund returns, it does not necessarily eliminate the Fund’s exposure to the non-U.S. dollar component currencies. The return of the foreign currency forward contracts may not perfectly offset the actual fluctuations in value between the non-U.S. dollar component currencies and the U.S. dollar.

The Fund may also use non-deliverable forward (“NDF”) contracts to execute its hedging transactions. An NDF contract is a contract where there is no physical settlement of two currencies at maturity. Rather, based on the movement of the currencies and the contractually agreed upon exchange rate, a net cash settlement will be made by one party to the other in U.S. dollars.

The Underlying Index is sponsored by Bloomberg, which is independent of the Fund and BFA. The Index Provider determines the composition and relative

weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

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

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. The order of the below risk factors does not indicate the significance of any particular risk factor.

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus

S-4

Table of Contents

(the “Prospectus”)) may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

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

Commodity Regulatory Risk. The Fund is deemed a commodity pool and BFA is considered a commodity pool operator (“CPO”) with respect to the Fund under the CEA. BFA is therefore subject to regulation by the SEC and the CFTC. BFA is also subject to regulation by the National Futures Association (“NFA”). The regulatory requirements governing the use of commodity futures,

options on commodity futures, certain swaps or certain other investments could change at any time.

Commodity Risk. The Fund invests in companies that are susceptible to fluctuations in certain commodity markets and to price changes due to trade relations. Any negative changes in commodity markets that may be due to changes in supply and demand for commodities, market events, war, regulatory developments, other catastrophic events, or other factors that the Fund cannot control could have an adverse impact on those companies.

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

Currency Hedging Risk. In seeking to track the “hedging” component of the Underlying Index, the Fund invests in currency forward contracts (which may include both physically-settled forward

S-5

Table of Contents

contracts and NDFs) designed to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and its reference asset, and there can be no assurance that the Fund’s hedging transactions will be effective.

Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions in a geographic region in which the Fund invests. In addition, in order to minimize transaction costs, or for other reasons, the Fund’s exposure to the non-U.S. dollar component currencies may not be fully hedged at all times. At certain times, the Fund may use an optimized hedging strategy and will hedge a smaller number of non-U.S. dollar component currencies to reduce hedging costs. Because currency forwards are over-the-counter instruments, the Fund is subject to counterparty risk as well as market or liquidity risk with respect to the hedging transactions the Fund enters into.

The effectiveness of the Fund’s currency hedging strategy will in general be affected by the volatility of both the Underlying Index and the volatility of the U.S. dollar relative to the currencies to be hedged, measured on an aggregate basis. Increased volatility in either or both of the Underlying Index and the U.S. dollar relative to the currencies to be hedged will generally reduce the effectiveness of the Fund’s currency hedging strategy. In addition, volatility in one or more of the currencies may offset stability in another currency and reduce the overall effectiveness of the

hedges. The effectiveness of the Fund’s currency hedging strategy may also in general be affected by interest rates. Significant differences between U.S. dollar interest rates and some or all of the applicable foreign currency interest rates may impact the effectiveness of the Fund’s currency hedging strategy.

Currency Risk. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if one or more of the currencies of the non-U.S. markets in which the Fund invests depreciates against the U.S. dollar and the depreciation of one currency is not offset by appreciation in another currency and/or the Fund's attempt to hedge currency exposure to the depreciating currency or currencies is unsuccessful. Generally, an increase in the value of the U.S. dollar against the non-U.S. dollar component currencies will reduce the value of a security denominated in such currencies, as applicable. In addition, fluctuations in the exchange rates between currencies could affect the economy or particular business operations of companies in a geographic region, including securities in which the Fund invests, causing an adverse impact on the Fund’s investments in the affected region and the U.S. As a result, investors have the potential for losses regardless of the length of time they intend to hold Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.

Custody Risk. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories.

S-6

Table of Contents

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, the Fund's adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Derivatives Risk. The Fund will use currency forwards and NDFs to hedge the currency exposure resulting from investments in the foreign currency-denominated securities held by the Fund. The Fund’s use of these instruments, like investments in other derivatives, may reduce the Fund’s returns, increase volatility and/or result in losses due to credit risk or ineffective hedging strategies. Volatility is defined as the characteristic of a security, a currency, an index or a market, to fluctuate significantly in price within a defined time period. Currency forwards, like other derivatives, are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.

A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the currency or currencies being hedged as compared to that of the U.S.

dollar. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. BFA’s use of derivatives is not intended to predict the direction of securities prices, currency exchange rates, interest rates and other economic factors, which could cause the Fund’s derivatives positions to lose value. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Regulatory requirements may make derivatives more costly, may limit the availability of derivatives, and may delay or restrict the exercise of remedies by the Fund upon a counterparty default under derivatives held by the Fund (which could result in losses), remedies or termination rights by the Fund, and may otherwise adversely affect the value and performance of derivatives. In addition, the Fund's use of derivatives may expose the Fund to risks related to potential operational issues, such as documentation and settlement issues, systems failures, inadequate controls and human error. Derivatives may also involve legal risks, including insufficient documentation, insufficient capacity or authority of a counterparty, and legality and enforceability of a contract.

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

S-7

Table of Contents

Fund’s income and potentially in the value of the Fund’s investments.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's investments in, or which are exposed to, the affected region.

Illiquid Investments Risk. The Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, the Fund will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund’s NAV.

Income Risk. The Fund's income may decline if interest rates fall. This decline

in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider, and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience

S-8

Table of Contents

temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in

the net asset value of the Fund to the extent that it invests in floating rate debt securities. The historically low interest rate environment in recent years heightens the risks associated with rising interest rates.

Management Risk. As the Fund will not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

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

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, losses due to ineffective currency hedges, periods of high volatility and disruptions

S-9

Table of Contents

in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with other funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities issued by or representing a small number of issuers or in derivatives with a limited number of counterparties. As a result, the Fund's performance may depend on the performance of a small number of issuers and counterparties.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

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

address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have privatized, or have begun the process of privatizing, certain entities and industries. Privatized entities may lose money or be re-nationalized.

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

Risk of Investing in China. Investments in bonds of Chinese issuers (including variable interest entities associated with an underlying Chinese operating company) subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency,

S-10

Table of Contents

volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.

Chinese issuers are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation.

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies

of China's key trading partners may have an adverse impact on the Chinese economy.

Chinese issuers are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as issuers in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese issuers, and investors may have limited legal remedies. The Fund is not actively managed and does not select investments based on investor protection considerations.

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

Market volatility and potential lack of liquidity due to low trading volume of certain bonds in the China Interbank Bond Market may result in prices of certain bonds to fluctuate significantly, and the systems used to trade in the

S-11

Table of Contents

market may not function as expected. Trading through Bond Connect is also subject to regulatory risks, including rules and regulations that are subject to change, and there can be no assurance that Bond Connect or certain features or systems thereof will not be materially altered, suspended, discontinued or abolished. The Fund may also be subject to additional taxation if certain tax exemptions under prevailing PRC tax regulations are withdrawn or amended. Any taxes arising from or to the Fund may be directly borne by, or indirectly passed on to, the Fund, which may result in a substantial impact to its NAV. Investing through Bond Connect subjects the Fund to currency risk, to the extent that currency rates used for Bond Connect are different than the rates used in the China Interbank Bond Market.

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

burdens and the price or availability of certain commodities.

Risk of Investing in Emerging Markets. Investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, social instability, political turmoil or rapid changes in economic conditions than more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Fund invests may be less reliable or complete. Emerging markets often have less reliable securities valuations and greater risk associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. The Fund is not actively managed and does not select investments based on investor protection considerations.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments in the U.S. and many other countries have imposed

S-12

Table of Contents

economic sanctions on certain Russian individuals and Russian corporate and banking entities. A number of jurisdictions may also institute broader sanctions on Russia. Recently, Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay

dividends, the Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.

Sovereign and Quasi-Sovereign Obligations Risk. The Fund invests in securities issued by or guaranteed by non-U.S. sovereign governments and by entities affiliated with or backed by non-U.S. sovereign governments, which may be unable or unwilling to repay principal or interest when due. In times of economic uncertainty, the prices of these securities may be more volatile than those of corporate debt obligations or of other government debt obligations.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”).

contracts. If the Fund were to perform such matching for income tax purposes, this matching would potentially result in the Fund’s deferral for U.S. federal income tax purposes of the realized gains or losses attributable to foreign currency forward contracts until such gains or losses offset the currency-related losses on the matched non-U.S. dollar denominated securities. If the IRS were to disagree with such deferral treatment or the matching methodology used, the Fund's income could become undistributed and incur tax liabilities. The Fund may reevaluate, adjust, begin, or discontinue the matching of such contracts in the future.

be heightened during times of increased market volatility or other unusual market conditions in the affected securities and/or foreign exchange markets. In addition, tracking error may result because the Fund incurs fees and expenses, while the Underlying Index does not, and because the Fund accepts creations and redemptions during time periods between which it is able to adjust its currency hedges, whereas the Underlying Index does not adjust its hedging during these periods. BFA EXPECTS THAT THE FUND WILL EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

securities or other instruments that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other instruments in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1 and 5 years and since inception compare with the Underlying Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Year by Year Returns (Years Ended December 31)

The best calendar quarter return during the periods shown above was 3.33% in the 1st quarter of 2016; the worst was -4.33% in the 2nd quarter of 2022.

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

Management

Investment Adviser and Sub-Advisers. The Fund's investment adviser is BlackRock Fund Advisors. The Fund’s sub-advisers are BlackRock International Limited (“BIL”) and BlackRock (Singapore) Limited (“BRS” and, together with BIL, the “Sub-Advisers”).

Portfolio Managers. John Hutson and James Mauro (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Hutson and Mr. Mauro have been Portfolio Managers of the Fund since 2022 and 2021, respectively.

Purchase and Sale of Fund Shares

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

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund and BIL and BRS are the Sub-Advisers to the Fund. Shares of the Fund are listed for trading on Cboe BZX Exchange, Inc. (“Cboe BZX”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents an ownership interest in an underlying portfolio of securities and other instruments intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by Authorized Participants and only in aggregations of a specified number of shares (“Creation Units”). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a currency hedged securities index that is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from the Fund's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index. From time to time, the Index Provider may make changes to the methodology or other adjustments to the Underlying Index. Unless otherwise determined by BFA, any such change or adjustment will be reflected in the calculation of the Underlying Index performance on a going-forward basis after the effective date of such change or adjustment. Therefore, the Underlying Index performance shown for periods prior to the effective date of any such change or adjustment will generally not be recalculated or restated to reflect such change or adjustment.

Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the

underlying index.

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

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments. The order of the below risk factors does not indicate the significance of any particular risk factor. The Fund discloses its portfolio holdings daily at www.iShares.com.

Asian Economic Risk. Many Asian economies have experienced rapid growth and industrialization in recent years, but there is no assurance that this growth rate will be maintained. Other Asian economies, however, have experienced high inflation, high unemployment, currency devaluations and restrictions, and over-extension of credit. Geopolitical hostility, political instability, and economic or environmental events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund invests. In particular, China is a key trading partner of many Asian countries and any changes in trading relationships between China and other Asian countries may affect the region as a whole. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Certain Asian countries have developed increasingly strained relationships with the U.S. or with China, and if these relations were to worsen, they could adversely affect Asian issuers that rely on the U.S. or China for trade. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund's investments.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, market segments, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental

Table of Contents

controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

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

Commodity Regulatory Risk. The Fund is deemed a “commodity pool” and BFA is considered a CPO with respect to the Fund under the CEA. BFA is therefore subject to regulation by the SEC and the CFTC. BFA is also subject to regulation by the NFA. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

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

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

Table of Contents

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, project types, group of project types, sector, market segment or asset class. The Fund may be more adversely affected by the underperformance of those securities and/or other assets, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities and/or other assets than a fund that does not concentrate its investments.

Credit Risk. Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments when due or otherwise honor its obligations. There are varying degrees of credit risk, depending on an issuer’s or counterparty’s financial condition and on the terms of an obligation, which may be reflected in the issuer’s or counterparty’s credit rating. There is the chance that the Fund’s portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing the Fund’s income level or share price. The Fund’s hedging strategy does not seek to mitigate credit risk.

Currency Hedging Risk. When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and its reference asset, and there can be no assurance that the Fund’s hedging transactions will be effective. In seeking to track the “hedging” component of the Underlying Index, the Fund invests in currency forward contracts, (which may include both physically-settled forward contracts and NDFs) designed to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio. NDFs may be less liquid than deliverable currency forward contracts and require the Fund to post variation margin to the counterparty, which can increase costs for the Fund. A lack of liquidity in NDFs of the hedged currency could result in the Fund being unable to structure its hedging transactions as intended. In addition, BFA may seek to limit the size of the Fund in order to attempt to reduce the likelihood of a situation where the Fund is unable to obtain sufficient liquidity in an underlying currency hedge to implement its investment objective.

Currency forward contracts, including NDFs, do not eliminate movements in the value of non-U.S. currencies and securities but rather allow the Fund to establish a fixed rate of exchange for a future point in time. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions in a geographic region in which the Fund invests. In addition, in order to minimize transaction costs, or for other reasons, the Fund’s exposure to the non-U.S. dollar component currencies may not be fully hedged at all times or the hedge may not be effective due to counterparty failures or otherwise. At certain times, the Fund may use an optimized hedging strategy and will hedge a smaller number of

Table of Contents

non-U.S. dollar component currencies to reduce hedging costs. Governments from time to time may intervene in the currency markets to influence prices and may adopt policies designed to influence foreign exchange rates with respect to their currency. Because the Fund’s currency hedge is reset on a monthly basis, currency risk can develop or increase intra-month. Furthermore, while the Fund is designed to hedge against currency fluctuations, it is possible that a degree of currency exposure may remain even at the time a hedging transaction is implemented. As a result, the Fund may not be able to structure its hedging transactions as anticipated or its hedging transactions may not successfully reduce the currency risk included in the Fund’s portfolio in a way that tracks the Underlying Index. Because currency forwards are over-the-counter instruments, the Fund is subject to counterparty risk as well as market or liquidity risk with respect to the hedging transactions the Fund enters into. Currency hedging activity exposes the Fund to credit risk due to counterparty exposure. This risk will be higher to the extent that the Fund trades with a single counterparty or small number of counterparties. In addition, the Fund’s currency hedging activities may involve frequent trading of currency instruments, which may increase transaction costs and cause the Fund’s return to deviate from the Underlying Index.

There is no assurance that the Fund’s strategy will be effective in hedging fluctuations in the value of these currencies against the U.S. dollar. The effectiveness of the Fund’s currency hedging strategy will in general be affected by the volatility of both the Underlying Index and the volatility of the U.S. dollar relative to the currencies to be hedged, measured on an aggregate basis. Increased volatility will generally reduce the effectiveness of the Fund’s currency hedging strategy. In addition, volatility in one or more of the currencies may offset stability in another currency and reduce the overall effectiveness of the hedges. The effectiveness of the Fund’s currency hedging strategy may also be affected by interest rates, which may differ among the affected countries. Significant differences between U.S. dollar interest rates and some or all of the applicable foreign currency interest rates may impact the effectiveness of the Fund’s currency hedging strategy. In addition, the currency hedging carried out by the Fund may result in lower returns than those generated through direct investments in the securities composing the Underlying Index when the local currency appreciates against the U.S. dollar.

Investors, such as the Fund, seeking to trade in foreign currencies may have limited access to certain currency markets due to a variety of factors, including government regulations, adverse tax treatment, exchange controls, currency convertibility issues and lack of market liquidity. These limitations and restrictions may impact the availability, liquidity and pricing of the financial instruments that are necessary for the Fund to hedge exposure to the currency markets. If the Fund’s ability to enter into contracts to purchase or sell the currency of a non-U.S. market in which the Fund invests is impaired, the Fund may not be able to achieve its investment objective. In addition, investments in currency forwards expose the Fund to the risks described under “Derivatives Risk.”

Currency Risk. Because the Fund's NAV is determined on the basis of the U.S. dollar, investors may lose money if one or more of the currencies of the non-U.S. markets in

Table of Contents

which the Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency and the depreciation of one currency is not offset by appreciation in another currency and/or the Fund’s attempt to hedge currency exposure to the depreciating currency or currencies is unsuccessful. Similarly, because the Fund seeks to hedge currency risk in accordance with the Underlying Index, investors may not share in appreciation in the securities comprising the Underlying Index to the extent that such appreciation is due to increases in the value of the underlying currencies. In addition, fluctuations in the exchange rates of currencies could affect the economy or particular business operations of companies in a geographic region in which the Fund invests, causing an adverse impact on the Fund’s investments in the affected region and the U.S. that is separate from the value of the underlying currency or currencies and, therefore, unmitigated by the hedging strategy used by the Fund. If this is the case, investors may experience better performance with a fund that is unhedged from a currency perspective than one that is hedged from a currency perspective, as is the case with the Fund. As a result, investors in the Fund have the potential for losses regardless of the length of time they intend to hold Fund shares and regardless of the effectiveness of the Fund’s currency hedging transactions. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades, as well as the holding of securities and other assets (such as currencies) by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s financial markets are, the higher the degree of custody risk.

Cybersecurity Risk. The Fund, Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through their service providers. Similar types of cybersecurity risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s investment in such issuers to lose value. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Recently, geopolitical tensions may have increased the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing.

Cybersecurity failures by, or breaches of, the systems of the Fund's adviser, distributor and other service providers (including, but not limited to, index and benchmark providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of

Table of Contents

securities in which the Fund invests have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyberattacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible, inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that prevention and remediation efforts will not be successful or that cyberattacks will go undetected. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Derivatives Risk. The Fund uses deliverable currency forwards and NDFs to hedge the currency exposure resulting from investments in foreign currency-denominated securities held by the Fund. The Fund’s use of these instruments, like investments in other derivatives, may reduce the Fund’s returns, increase volatility and/or result in losses due to credit risk or ineffective hedging strategies. Volatility is defined as the characteristic of a security, a currency, an index or a market, to fluctuate significantly in price within a defined period. Currency forwards, like other derivatives, are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the currency or currencies being hedged. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. BFA’s use of derivatives is not intended to predict the direction of securities prices, currency exchange rates, interest rates and other economic factors, which could cause the Fund’s derivatives positions to lose value. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Regulatory requirements affecting the use of derivatives may make derivatives more costly, and may delay or restrict the exercise of remedies by the Fund upon a counterparty default under derivatives held by the Fund (which could result in losses). In addition, the Fund's use of derivatives may expose the Fund to risks related to potential operational issues, such as documentation and settlement issues, systems failures, inadequate controls and human error. Derivatives may also involve legal risks, including insufficient documentation, insufficient capacity or authority of a counterparty, and legality and enforceability of a contract.

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

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The U.K. left the EU (“Brexit”) on January 31, 2020. The U.K. and EU reached an agreement on the terms of their future trading relationship effective January 1, 2021, which principally relates to the trading of goods rather than services, including financial services. Further discussions are to be held between the U.K. and the EU in relation to matters not covered by the trade agreement, such as financial services. The Fund faces risks associated with the potential uncertainty and consequences that may follow Brexit, including with respect to volatility in exchange rates and interest rates. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets. Brexit has also led to legal uncertainty and could lead to politically divergent national laws and regulations as a new relationship between the U.K. and EU is defined and the U.K. determines which EU laws to replace or replicate. Any of these effects could adversely affect any of the companies to which the Fund has exposure and any other assets in which the Fund invests. The political, economic and legal consequences of Brexit are not yet fully known. In the short term, financial markets may experience heightened volatility, particularly those in the U.K. and Europe, but possibly worldwide. The U.K. and Europe may be less stable than they have been in recent years, and investments in the U.K. and the EU may be difficult to value or subject to greater or more frequent volatility. In the longer term, there is likely to be

Table of Contents

a period of significant political, regulatory and commercial uncertainty as the U.K. continues to negotiate the terms of its future trading relationships.

Secessionist movements, such as the Catalan movement in Spain and the independence movement in Scotland, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. In addition, the national politics of countries in the EU have been unpredictable and subject to influence by disruptive political groups and ideologies. The governments of EU countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe or war in the region could also impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

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

Geographic Risk. Some of the companies in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, tornadoes, volcanic eruptions, droughts, floods, hurricanes or tsunamis, and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of the Fund.

Table of Contents

as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an illiquid investment pursuant to the Fund’s liquidity risk management program. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. An investment may be illiquid due to, among other things, the reduced number and capacity of traditional market participants to make a market in securities or instruments, the lack of an active market for such securities or instruments, capital controls, delays or limits on repatriation of local currency, or insolvency of local governments. To the extent that the Fund invests in securities or instruments with substantial market and/or credit risk, the Fund will tend to have increased exposure to the risks associated with illiquid investments. Illiquid investments may be harder to value, especially in changing markets. Although the Fund primarily seeks to redeem shares of the Fund on an in-kind basis, if the Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be magnified in a rising interest rate environment or other circumstances where redemptions from the Fund may be greater than normal. Other market participants may be attempting to liquidate holdings at the same time as the Fund, causing increased supply of the Fund’s underlying investments in the market and contributing to illiquid investments risk and downward pricing pressure. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, the Fund will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund's NAV.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds, as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund otherwise needs to purchase additional bonds. The Index Provider’s substitution of bonds in the Underlying Index may occur, for example, when the time to maturity for the bond no longer matches the Underlying Index’s stated maturity guidelines.

Index-Related Risk. The Fund seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider or any agents that may act on its behalf will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or

Table of Contents

any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. In addition, there may be heightened risks associated with the adequacy and reliability of the information the Index Provider uses given the Fund's exposure to emerging markets, as certain emerging markets may have less information available or less regulatory oversight. Such errors may negatively or positively impact the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Shareholders should understand that any gains from Index Provider errors will be kept by the Fund and its shareholders and any losses or costs resulting from Index Provider errors will be borne by the Fund and its shareholders.

Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider, and could cause the Index Provider to postpone a scheduled rebalance to the Underlying Index. This could cause the Underlying Index to vary from its normal or expected composition. The postponement of a scheduled rebalance could mean that constituents of the Underlying Index that would otherwise be removed at rebalance due to changes in market value, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Underlying Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Index due to reaching certain weighting constraints, unusual market conditions or corporate events or, for example, to correct an error in the selection of index constituents. When the Underlying Index is rebalanced and the Fund in turn rebalances its portfolio to attempt to increase the correlation between the Fund’s portfolio and the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may adversely affect the economies of many nations and the global economy and may impact individual issuers and capital markets in ways that cannot be foreseen.

An infectious illness outbreak may result in travel restrictions, closed international borders, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, temporary and permanent closures of businesses, layoffs, defaults and other significant economic, social and political impacts, as well as general concern and uncertainty.

An infectious illness outbreak may result in extreme volatility, severe losses, credit deterioration of issuers, and disruptions in markets, which could adversely impact the Fund and its investments, including impairing any hedging activity.

Table of Contents

Certain local markets may be subject to closures. Any suspension of trading in markets in which the Fund invests will have an impact on the Fund and its investments and will impact the Fund’s ability to purchase or sell securities in such markets. Market or economic disruptions could result in elevated tracking error and increased premiums or discounts to the Fund's NAV. Additionally, an outbreak could impair the operations of the Fund’s service providers, including BFA, which could adversely impact the Fund.

Governmental and quasi-governmental authorities and regulators throughout the world may respond to an outbreak and any resulting economic disruptions with a variety of fiscal and monetary policy changes, including direct capital infusions into companies and other issuers, new monetary policy tools, and changes in interest rates. A reversal of these policies, or the ineffectiveness of such policies, is likely to increase market volatility, which could adversely affect the Fund’s investments.

An outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally, which could adversely affect the Fund and its investments and could result in increased premiums or discounts to the Fund's NAV.

Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Interest Rate Risk. If interest rates rise, the value of fixed-income securities or other instruments held by the Fund would likely decrease. A measure investors commonly use to determine this price sensitivity is called duration. Fixed-income 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. For example, if a bond has a duration of five years and interest rates rise, the price of the bond will likely decline by a greater percentage than if the bond had a one year duration. To the extent the Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Fund's investments to decline significantly, which would adversely affect the value of the Fund. An increase in interest rates may lead to heightened volatility in the fixed-income markets and adversely affect certain fixed-income investments, including those held by the Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. In addition, decreases in fixed income dealer market-making capacity may lead to lower trading volume, heightened volatility, wider bid-ask spreads and less transparent pricing in certain fixed-income markets.

The historically low interest rate environment in recent years was created in part by the world’s major central banks keeping their overnight policy interest rates at, near or below zero percent and implementing monetary policy facilities, such as asset purchase programs, to anchor longer-term interest rates below historical levels. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Certain countries have recently experienced negative interest rates on certain fixed-income instruments. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result

Table of Contents

in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are set at low levels and the market prices of portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. Central banks may increase their short-term policy rates or begin phasing out, or “tapering,” accommodative monetary policy facilities in the future. The timing, coordination, magnitude and effect of such policy changes on various markets are uncertain, and such changes in monetary policy may adversely affect the value of the Fund’s investments.

Issuer Risk. The performance of the Fund depends on the performance of individual securities and other instruments to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the Fund is unable or unwilling to repay principal or interest when due. Any issuer of these securities or counterparty on other instruments may perform poorly, causing the value of its securities or instruments to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Management Risk. Because BFA uses a representative sampling indexing strategy, the Fund will not fully replicate the Underlying Index and may hold securities and other instruments not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Market risk arises mainly from uncertainty about future values of financial instruments and may be influenced by price, currency and interest rate movements. It represents the potential loss the Fund may suffer through holding financial instruments in the face of market movements or uncertainty. The value of a security, asset, or other instrument may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV. During a general market downturn, multiple asset classes may be negatively affected. Fixed-income securities with short-term maturities are generally less sensitive to such changes than are fixed-income securities with longer-term maturities. Changes in

Table of Contents

market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk.

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

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

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

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

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

Table of Contents

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

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

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with other funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities issued by or representing a small number of issuers or in derivatives with a limited number of counterparties. As a result, the Fund may be more susceptible to the risks associated with these particular issuers or counterparties or to a single economic, political or regulatory occurrence affecting these issuers or counterparties.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers have different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, uncertainties of transnational litigation, and potential restrictions on the flow of international capital, including the possible seizure or nationalization of the securities

Table of Contents

issued by non-U.S. issuers held by the Fund. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. Unfavorable political, economic or governmental developments in non-U.S. countries could affect the payment of a security’s principal and interest. Securities issued by non-U.S. issuers may also be less liquid than, and more difficult to value than, securities of U.S. issuers. In addition, the value of these securities may fluctuate due to changes in the exchange rate of the issuer’s local currency against the U.S. dollar.

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

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

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

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have privatized, or have begun the process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur.

Reliance on Trading Partners Risk. Economies in developed countries generally are heavily dependent upon commodity prices and international trade and, accordingly, have been and may continue to be affected adversely by the economies of their trading partners, trade barriers, exchange controls, and managed adjustments in relative currency values, and may suffer from extreme and volatile debt burdens or inflation rates. These countries may be subject to other protectionist measures imposed or negotiated by the countries with which they trade, including the imposition of tariffs by the U.S. or other importing countries.

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

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance that these reforms will continue or that they will be effective. Despite recent reform and privatizations, government control over certain sectors or enterprises and significant regulation of investment and industry is still pervasive, including restrictions on investment in companies or industries deemed to be sensitive to particular national interests, trading of securities of Chinese issuers, foreign ownership of Chinese corporations and/or the repatriation of assets by foreign investors. Limitations or restrictions on foreign ownership of securities may have adverse effects on the liquidity and performance of the Fund and could lead to higher tracking error. Chinese government intervention in the market may have a negative impact on market sentiment, which may in turn affect the performance of the Chinese economy and the Fund’s investments. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, lack of publicly available information, and political and social instability. Chinese issuers, such as those in the financial services or technology sectors, and potentially other sectors are also subject to the risk that Chinese authorities can intervene in their operations and structure, which may negatively affect the value of the Fund's investments.

Economic Risk. The Chinese economy has grown rapidly in the recent past, and there is no assurance that this growth rate will be maintained. In fact, the Chinese economy

Table of Contents

may experience a significant slowdown as a result of, among other things, a deterioration in global demand for Chinese exports, as well as a contraction in spending on domestic goods by Chinese consumers. In addition, China may experience substantial rates of inflation or economic recessions, which would have a negative effect on its economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered the performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates. Reduction in spending on Chinese products and services, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy and the Chinese issuers of securities in which the Fund invests. For example, the U.S. has added certain foreign technology companies to the U.S. Department of Commerce’s Bureau of Industry and Security’s “Entity List,” which is a list of companies believed to pose a national security risk to the U.S. Actions like these may have unanticipated and disruptive effects on the Chinese economy. Any such response that targets Chinese financial markets or securities exchanges could interfere with orderly trading, delay settlement or cause market disruptions.

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

Security Risk. China has strained international relations with Taiwan, Japan, India, Russia and other neighbors due to territorial disputes, historical animosities, defense concerns and other security concerns. Heightened tensions or an outbreak of hostilities between China and Taiwan may adversely impact China’s economy as well as the global economy and the value of the Fund’s investments. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy. Such risks, among others, may adversely affect the value of the Fund’s investments.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region of the PRC under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Since 1997, there have been tensions between the Chinese government and many people in

Table of Contents

Hong Kong who perceive China as tightening control over Hong Kong’s semi-autonomous liberal political, economic, legal and social framework. Recent protests and unrest have increased tensions even further. Due to the interconnected nature of the Hong Kong and Chinese economies, this instability in Hong Kong may cause uncertainty in the Hong Kong and Chinese markets. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because the Fund's NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund's NAV.

Limited Information and Legal Remedies. Chinese issuers are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as issuers in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese issuers, and investors may have limited legal remedies. The Fund is not actively managed and does not select investments based on investor protection considerations.

Risk of Investing in the China Bond Market. The Fund invests directly in the China Interbank Bond Market through the northbound trading of Bond Connect. Bond Connect allows investors to trade between the mainland China and Hong Kong markets electronically, which eliminates the need for investor status and quotas that were required under previous access models. Under the prevailing regulations in the PRC, eligible foreign investors such as the Fund are allowed to invest in the bonds circulated in the China Interbank Bond Market through Bond Connect. The settlement and custody of bonds traded in the China Interbank Bond Market under Bond Connect will be effected through the settlement and custody link between CMU, as an offshore custody agent, and CCDC and SCH, as onshore custodians and clearing institutions in the PRC. All bonds traded by eligible foreign investors through Bond Connect will be registered in the name of CMU, which will hold such bonds as a nominee owner. Therefore, the Fund will be exposed to custody risks with respect to CMU. In addition, as the relevant filings, registration with the People’s Bank of China, and account opening have to be carried out by third parties, including CMU, CCDC, and SCH, the Fund is subject to the risks of default or errors and omissions on the part of such third parties and may have limited remedies or no legal recourse at all to cure such defaults, errors and omissions.

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

Table of Contents

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

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

Trading through Bond Connect is performed through newly developed trading platforms and operational systems. There is no assurance that such systems will function as expected or will continue to be adapted to changes and developments in the market. In the event that a relevant system does not function as expected, trading through Bond Connect may be disrupted. The Fund's ability to trade through Bond Connect (and hence to pursue its investment strategy) may therefore be adversely affected. In addition, where the Fund invests in the China Interbank Bond Market through Bond Connect, it may be subject to risks of delays inherent in the order placing and/or settlement systems.

Bond Connect trades are settled in Chinese currency, the renminbi (“RMB”). This means that the Fund will be exposed to currency risk, and it cannot be guaranteed that investors will have timely access to a reliable supply of RMB. The RMB consists of an onshore RMB (“CNY”) and an offshore RMB (“CNH”). The CNY is the official currency of the PRC and is the currency of denomination for all financial transactions between individuals, the state and corporations in the PRC. Hong Kong is the first jurisdiction to allow for the accumulation of RMB deposits in the form of CNH outside the PRC. Since 2010, the CNH market is traded officially and regulated jointly by the Hong Kong Monetary Authority and the PBOC. While CNY and CNH are the same currency, they are traded in different and separate markets. Therefore, CNY and CNH can be subject to different liquidity constraints and market forces, meaning their valuations can vary. The RMB-denominated bonds included in the Underlying Index use CNY as the base currency. As a result, to the extent that the Fund holds RMB-denominated instruments

Table of Contents

in CNH, it could be subject to tracking error and potential foreign exchange transaction costs associated with converting from CNH to CNY (and vice versa).

Under prevailing tax regulations, a 10% withholding tax is imposed on PRC-sourced dividends and interest from non-government bonds paid to the Fund unless the rate is reduced under an applicable tax treaty. Value Added Tax (“VAT”) is levied on certain income derived by the Fund, including interest income from non-government bonds and trading gains, unless specifically exempted by the PRC tax authorities. VAT exemptions currently apply to debt securities traded in the China Interbank Bond Market. On November 22, 2018, the PRC’s Ministry of Finance and State Administration of Taxation jointly issued Circular 108 providing foreign institutional investors with a temporary exemption from withholding income tax and VAT with respect to interest income derived from non-government bonds in the domestic bond market for the period from November 7, 2018 to November 6, 2021. On November 26, 2021, the PRC's Ministry of Finance and State Administration of Taxation jointly issued Circular 34 to extend the tax exemption period provided in Circular 108 to December 31, 2025. Circular 108 is silent on the PRC tax treatment with respect to non-government bond interest derived prior to November 7, 2018. There is a risk the PRC tax authorities may withdraw the temporary tax exemptions in the future and seek to collect withholding income tax and VAT on interest income from non-government bonds to the Fund without prior notice. If the tax exemptions are withdrawn, any taxes arising from or to the Fund may be directly borne by or indirectly passed on to the Fund, which may result in a substantial impact to its NAV. As with any NAV adjustment, investors may be advantaged or disadvantaged depending on when the investors purchased or sold shares of the Fund. Any changes in PRC tax law, future clarifications thereof, and/or subsequent retroactive enforcement by the PRC tax authorities may result in a loss which could be material to the Fund. BFA will keep the provisioning policy for tax liability under review and may, in its discretion from time to time, make a provision for potential tax liabilities if in its opinion such provision is warranted or as further publicly clarified by the PRC.

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

Table of Contents

certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

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

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

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

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

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

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

Table of Contents

portfolio securities and could have an adverse effect on the Fund in seeking to achieve its investment objective.

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

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Risk of Investing in Emerging Markets” and “Non-U.S. Issuers Risk,” that are not typically associated with investing in U.S. securities, including:

■	The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
■	Risks in connection with the maintenance of the Fund’s portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
■	The risk that the Fund’s ownership rights in portfolio securities could be lost through fraud or negligence because ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system;
■	The risk that the Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the Russian government; and
■	The risk that various responses by other nation-states to alleged Russian cyber activity will impact Russia’s economy and Russian issuers of securities in which the Fund invests.

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

Table of Contents

Russia Sanctions. Governments in the U.S. and many other countries (collectively, the “Sanctioning Bodies”) have imposed economic sanctions on certain Russian individuals, including politicians, and Russian corporate and banking entities, including banning Russia from global payments systems that facilitate cross-border payments. The Sanctioning Bodies, or others, could also institute broader sanctions on Russia. 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. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of the Fund to buy, sell, receive or deliver those securities and/or assets.

The sanctions against certain Russian issuers include prohibitions on transacting in or dealing in issuances of debt or equity of such issuers. Compliance with each of these sanctions has and may continue to impair the ability of the Fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. If it becomes impracticable or unlawful for the Fund to hold securities subject to, or otherwise affected by, sanctions (collectively, “affected securities”), or if deemed appropriate by BFA, the Fund may prohibit in-kind deposits of the affected securities in connection with creation transactions and instead require a cash deposit, which may also increase the Fund's transaction costs. The Fund may also be legally required to freeze assets in a blocked account.

Sanctions have resulted in Russia taking counter measures or retaliatory actions, which has impaired the value and liquidity of Russian securities. These retaliatory measures include the immediate freeze of Russian assets held by the Fund. Due to the freeze of these assets, including depositary receipts, the Fund may need to liquidate non-restricted assets in order to satisfy any Fund redemption orders. The liquidation of Fund assets during this time may also result in the Fund receiving substantially lower prices for its securities. Russia may implement additional retaliatory measures, which may further impair the value and liquidity of Russian securities and the ability of the Fund to receive dividend payments. Recently, Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibits Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund may be unable to receive them.

These sanctions, the decision by Russia to suspend trading on the Moscow Exchange (MOEX) and prohibit non-resident investors from executing security sales, and other events have led to changes in the Fund's Underlying Index. The Fund’s Index Provider has removed Russian securities from the Underlying Index. To the extent that the Fund rebalances its portfolio and trades in non-Russian securities to seek to track the investment results of the Underlying Index, this may result in transaction costs and increased tracking error. The Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian securities. This disparity will also lead to increased tracking error. The inability of the Fund to trade in Russian securities may adversely affect the Fund’s ability to

Table of Contents

meet its investment objective. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.

Also, if an affected security is included in the Fund's Underlying Index, the Fund may, where practicable, seek to eliminate its holdings of the affected security by employing or augmenting its representative sampling strategy to seek to track the investment results of its Underlying Index. The use of (or increased use of) a representative sampling strategy may increase the Fund’s tracking error risk. If the affected securities constitute a significant percentage of the Underlying Index, the Fund may not be able to effectively implement a representative sampling strategy, which may result in significant tracking error between the Fund’s performance and the performance of its Underlying Index.

Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fund) to invest in the securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. In addition, the Saudi Arabian government places investment limitations on the ownership of Saudi Arabian issuers by foreign investors, including a limitation on the Fund’s ownership of any single issuer listed on the Saudi Arabian Stock Exchange, which may prevent the Fund from investing in accordance with its strategy and contribute to tracking error against the Underlying Index. Saudi Arabia is highly reliant on income from the sale of petroleum and trade with other countries involved in the sale of petroleum, and its economy is therefore vulnerable to changes in foreign currency values and the market for petroleum. As global demand for petroleum fluctuates, Saudi Arabia may be significantly impacted. Like most Middle Eastern governments, the government of Saudi Arabia exercises substantial influence over many aspects of the private sector. Although liberalization in the wider economy is underway, in many areas it has lagged significantly: restrictions on foreign ownership persist, and the government has an ownership stake in many key industries. The situation is exacerbated by the fact that Saudi Arabia is governed by an absolute monarchy. Saudi Arabia has historically experienced strained relations with economic partners worldwide, including other countries in the Middle East due to geopolitical events. Governmental actions in the future could have a significant effect on economic conditions in Saudi Arabia, which could affect private sector companies and the Fund, as well as the value of securities in the Fund’s portfolio. Any economic sanctions on Saudi Arabian individuals or Saudi Arabian corporate entities, or even the threat of sanctions, may result in the decline of the value and liquidity of Saudi Arabian securities, a weakening of the Saudi riyal or other adverse consequences to the Saudi Arabian economy. In addition, Saudi Arabia’s economy relies heavily on cheap, foreign labor, and changes in the availability of this labor supply could have an adverse effect on the economy.

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

Table of Contents

decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. Although the political situation in Saudi Arabia is largely stable, Saudi Arabia has historically experienced political instability, and there remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia. Political instability in the larger Middle East region has caused significant disruptions to many industries. Continued political and social unrest in these areas may negatively affect the value of securities in the Fund’s portfolio.

Sovereign and Quasi-Sovereign Obligations Risk. An investment in sovereign or quasi-sovereign debt obligations involves special risks not present in corporate debt obligations. Sovereign debt includes securities issued by or guaranteed by a foreign sovereign government, and quasi-sovereign debt includes securities issued by or guaranteed by an entity affiliated with or backed by a sovereign government. The issuer of the sovereign debt that controls the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of a sovereign debt obligation to decline. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of corporate debt obligations and may affect the Fund's NAV. Quasi-sovereign debt obligations are typically less liquid and less standardized than sovereign debt obligations. These risks may be more pronounced with respect to non-U.S. sovereign debt than with respect to U.S. government debt. Several countries in which the Fund invests have defaulted on their sovereign debt obligations in the past or encountered downgrades of their sovereign debt obligations, and those countries (or other countries) may default or risk further downgrades in the future.

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

As part of the Fund's currency hedging strategy, the Fund may match foreign currency forward contracts with the non-U.S. dollar denominated securities whose currency risk is intended to be hedged wholly or partially by such contracts. If the Fund were to perform such matching for income tax purposes, this matching would potentially result in the Fund’s deferral for U.S. federal income tax purposes of the realized gains or losses attributable to foreign currency forward contracts until such gains or losses offset the currency-related losses on the matched non-U.S. dollar denominated securities. If the IRS were to disagree with such deferral treatment or the matching methodology used, the Fund's income could become undistributed and incur tax

Table of Contents

liabilities. The Fund may reevaluate, adjust, begin, or discontinue the matching of such contracts in the future.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), transaction and hedging costs incurred and forward rates achieved by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or other distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, changes to the Underlying Index and the cost to the Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions in the affected securities and/or foreign exchange markets. In addition, tracking error may result because the Fund incurs fees and expenses, while the Underlying Index does not, and because the Fund accepts creations and redemptions during time periods between which it is able to adjust its currency hedges, whereas the Underlying Index does not adjust its hedging during these periods. BFA EXPECTS THAT THE FUND WILL EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Valuation Risk. The price the Fund could receive upon the sale of a security or unwind of a financial instrument or other asset may differ from the Fund's valuation of the security, instrument or other asset and from the value used by the Underlying Index, particularly for securities or other instruments that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because non-U.S. exchanges may be open on days or during time periods when the Fund does not price its shares, the value of the securities or other instruments in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is translated into U.S. dollars at the prevailing market rates. This translation may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies. The order of the below risk factors does not indicate the significance of any particular risk factor.

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

Government Debt Risk. Investment in debt instruments issued or guaranteed by foreign sovereign governments can involve a high degree of risk. The governmental entity that controls the repayment of debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt. A governmental entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy towards the International Monetary Fund and the political constraints to which a governmental entity may be subject. Governmental entities also may be dependent on expected disbursements from other foreign governments, multilateral agencies and others abroad to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on the implementation of economic reforms and/or economic performance and the timely service of such debtor’s obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties’ commitments to lend funds to the governmental entity, which may further impair such debtor’s ability or willingness to timely service its debts. Consequently, governmental entities may default on their debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. In the past, certain governments’ countries have refused to honor their payment obligations on issued debt.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares or may invest in the Fund and

Table of Contents

hold their investment for a limited period of time. These shareholders may also pledge or loan Fund shares (to secure financing or otherwise), which may result in the shares becoming concentrated in another party. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment or that the size of the Fund would be maintained. Redemptions of a large number of Fund shares by these shareholders may adversely affect the Fund’s liquidity and net assets. To the extent the Fund permits redemptions in cash, these redemptions may force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund’s NAV, have a material effect on the market price of the Shares and increase the Fund’s brokerage costs and/or accelerate the realization of taxable income and/or gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. The Fund also may be required to sell its more liquid Fund investments to meet a large redemption, in which case the Fund’s remaining assets may be less liquid, more volatile, and more difficult to price. To the extent these large shareholders transact in shares on the secondary market, such transactions may account for a large percentage of the trading volume for the shares of the Fund and may, therefore, have a material upward or downward effect on the market price of the Fund shares. In addition, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, diluting its investment returns.

Non-U.S. Agency Debt Risk. The Fund invests in uncollateralized bonds issued by agencies, subdivisions or instrumentalities of foreign governments. Bonds issued by these foreign government agencies, subdivisions or instrumentalities are generally backed only by the creditworthiness and reputation of the entities issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to actually provide that support. If a non-U.S. agency is unable to meet its obligations, the performance of the Fund will be adversely impacted. A non-U.S. agency’s operations and financial condition are influenced by the foreign government’s economic and other policies. Changes to the financial condition or credit rating of a foreign government may cause the value of debt issued by that particular foreign government’s agencies, subdivisions or instrumentalities to decline. During periods of economic uncertainty, the trading of non-U.S. agency bonds may be less liquid while market prices may be more volatile than prices of U.S. agency bonds. Additional risks associated with non-U.S. agency investing include differences in accounting, auditing and financial reporting standards, adverse changes in investment or exchange control regulations, political instability, which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S under the 1933 Act. Privately issued securities typically may be resold only to qualified institutional buyers, or in a privately negotiated transaction, or to a limited number of

Table of Contents

purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund may find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held and traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s NAV due to the absence of an active trading market. There can be no assurance that a privately issued security that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund, and its value may decline as a result.

Threshold/Underinvestment Risk. If certain aggregate and/or fund-level ownership thresholds are reached through transactions undertaken by BFA, its affiliates or the Fund, or as a result of third-party transactions or actions by an issuer or regulator, the ability of BFA and its affiliates on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

For example, in certain circumstances where the Fund invests in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, is subject to corporate or regulatory ownership restrictions, or invests in certain futures or other derivative transactions, there may be limits on the aggregate and/or fund-level amount invested or voted by BFA and its affiliates for their proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BFA and its affiliates, the Fund or other client accounts to suffer disadvantages or business restrictions.

Portfolio Holdings Information

A description of the Trust's policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund's Statement of Additional Information (“SAI”). The Fund discloses its portfolio holdings daily at www.iShares.com. Fund fact sheets provide information regarding the Fund's top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Fund. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management

Table of Contents

affiliates with respect to certain portfolio securities. In seeking to achieve the Fund's investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

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

For the fiscal year ended October 31, 2022, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund based on a percentage of the Fund's average daily net assets, at the annual rate of 0.07%. From November 1, 2021 through March 30, 2022, the management fee was 0.08%; effective March 31, 2022, the management fee is 0.07%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

BFA has entered into separate sub-advisory agreements (each, a “Sub-Advisory Agreement”) with BIL and BRS, each an affiliate of BFA, under which BFA pays each of the Sub-Advisers for services it provides either: (i) a fee equal to a percentage of the management fee paid to BFA under the Investment Advisory Agreement or (ii) an amount based on the cost of the services provided. The Sub-Advisers, subject to the supervision and oversight of the Trust's Board of Trustees (the “Board”) and BFA, are primarily responsible for the execution of securities transactions and management of specified assets outside the U.S. and Canada (for BIL) and in the People's Republic of China (for BRS) in the Fund’s portfolio. If a Sub-Adviser provides services relating to both portfolio management and trading, it is entitled to receive from BFA an amount equal to 20% of BFA’s management fee, and if a Sub-Adviser provides services related solely to trading, then it is entitled to receive from BFA an amount equal to 110% of the actual pre-tax costs incurred by the Sub-Adviser.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is an indirect wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”). As of December 31, 2022, BFA and its affiliates provided investment advisory services for assets in excess of $8.6 trillion. BIL is a registered investment adviser, organized in 1999, located in the U.K. at Exchange Place One, 1 Semple Street, Edinburgh EH3 8BL, Scotland 011 44 131 472 7200. BRS is a registered investment adviser, organized in 2000, located in Singapore at 20 Anson Road #18-01, 079912, Singapore. BFA and its affiliates trade and invest for their own accounts in the actual securities and types of securities in which the Fund may also invest, which may affect the price of such securities. BFA is considered a “commodity pool operator” with respect to the Fund under the CEA and is therefore subject to regulation by the SEC and the CFTC with respect to the Fund.

A discussion regarding the basis for the approval by the Board of the Investment Advisory Agreement with BFA, the Sub-Advisory Agreement between BFA and BIL and

Table of Contents

the Sub-Advisory Agreement between BFA and BRS is available in the Fund's Annual Report for the period ended October 31.

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

John Hutson has been employed by BlackRock as a Managing Director since 2011. Mr. Hutson was employed by State Street Global Advisors as a portfolio manager from 2001 to 2011. Mr. Hutson has been a Portfolio Manager of the Fund since 2022.

James Mauro has been employed by BFA or its affiliates as a portfolio manager since 2011. Prior to that, Mr. Mauro was a Vice President at State Street Global Advisors. Mr. Mauro has been a Portfolio Manager of the Fund since 2021.

The Fund's SAI provides additional information about the Portfolio Managers' compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers' ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund. JPMorgan Chase Bank, N.A. serves as custodian for the Fund in connection with certain securities lending activities.

Conflicts of Interest. The investment activities of BFA and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Fund. BFA and its Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more Affiliates act, or may act, as an investor, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, trader, lender, index provider, agent and/or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. The Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has significant debt or equity investments or other interests. The Fund may also invest in issuances (such as structured notes) by entities for which an Affiliate provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and

Table of Contents

purchase or distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. BFA or one or more Affiliates may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund. This may include transactions in securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”)). The trading activities of BFA and these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate having positions in certain securities that are senior or junior to, or have interests different from or adverse to, the securities that are owned by the Fund.

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

In addition, the Fund may, from time to time, enter into transactions in which BFA or an Affiliate or its or their directors, officers, employees or clients have an adverse interest. Furthermore, transactions undertaken by clients advised or managed by BFA or its Affiliates may adversely impact the Fund. Transactions by one or more clients or by BFA or its Affiliates or their directors, officers or employees may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to BFA or one or more Affiliates and/or their internal policies designed to comply with such restrictions.

It is also possible that, from time to time, BlackRock and/or its advisory clients (including other funds and separately managed accounts) may, subject to compliance with applicable law, purchase and hold shares of the Fund. The price, availability, liquidity, and (in some cases) expense ratio of the Fund may be impacted by purchases and sales of the Fund by BlackRock and/or its advisory clients.

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

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange or otherwise in the secondary market. The Fund's shares trade under the ticker symbol “IAGG.”

Buying or selling Fund shares on an exchange or other secondary market involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the Fund’s trading volume and market liquidity, and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The Fund's spread may also be impacted by the liquidity or illiquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

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

The national securities exchange on which the Fund's shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is Cboe BZX.

Section 12(d)(1) of the 1940 Act generally restricts investments by investment companies, including foreign and unregistered investment companies, in the securities of other investment companies. For example, a registered investment company (the “Acquired Fund”), such as the Fund, may not knowingly sell or otherwise dispose of any security issued by the Acquired Fund to any investment company (the “Acquiring Fund”) or any company or companies controlled by the Acquiring Fund if, immediately after such sale or disposition: (i) more than 3% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and any company or companies controlled by the Acquiring Fund, or (ii) more than 10% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and other investment companies and companies controlled by them. However, registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) in reliance on Rule 12d1-4 under the 1940 Act, the registered investment company must, among other things, enter into an agreement with the Trust. Foreign investment companies are permitted to invest in the Fund only up to the limits set forth in Section 12(d)(1), subject to any applicable SEC no-action relief.

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

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

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and underlying securities held by the Fund, economic conditions and other factors.

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

Table of Contents

any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund is determined pursuant to BFA’s valuation policies and procedures. BFA has been designated by the Board as the valuation designee for the Fund pursuant to Rule 2a-5 under the Investment Company Act.

The Fund values fixed-income portfolio securities using last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund's approved independent third-party pricing services, each in accordance with BFA's valuation policies and procedures. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Fund may hold or transact in such securities in smaller odd lot sizes. Odd lots often trade at lower prices than institutional round lots. An amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BFA determines in good faith that such method does not represent fair value.

Generally, trading in non-U.S. securities and money market instruments is substantially completed each day at various times prior to the close of regular trading hours of the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, BFA will fair value the Fund’s investments in accordance with its policies and procedures. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of trading or other reasons, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the last exchange closing price or closing market price of one or more assets held by, or liabilities of, the Fund.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value

Table of Contents

prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

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

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

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

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

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income, including distributions out of the Fund's net short-term capital gains, if any, are taxable to you as ordinary income. The Fund's distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains, regardless of how long you have held the shares. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. Distributions from the Fund are subject to a 3.8% U.S. federal Medicare contribution tax on “net investment income,” for individuals with incomes exceeding $200,000 ($250,000 if married and filing jointly) and of estates and trusts. In general, your distributions are

Table of Contents

subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year. Certain states and localities may exempt from tax distributions attributable to interest from U.S. federal government obligations.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund.

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

Dividends, interest and capital gains earned by the Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

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

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

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items paid to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including

Table of Contents

the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

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

Taxes When Shares Are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax advisor about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor” or “BRIL”), an affiliate of BFA. An Authorized Participant is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities, assets or other positions (a “creation basket”), and an amount of cash (including any cash representing the value of substituted securities, assets or other positions), if any, which together approximate the holdings of the Fund in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities,

Table of Contents

assets or other positions (a “redemption basket”) held by the Fund and an amount of cash (including any portion of such securities for which cash may be substituted). The Fund may, in certain circumstances, offer Creation Units partially or solely for cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund. Creation and redemption baskets may differ and the Fund will accept “custom baskets.” More information regarding custom baskets is contained in the Fund's SAI.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

Only an Authorized Participant may create or redeem Creation Units with the Fund. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Fund.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

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

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund's SAI.

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

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

Distribution

The Distributor or its agent distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 1 University Square Drive, Princeton, NJ 08540.

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