Supplement dated April 1, 2020 (the “Supplement”)to the Summary Prospectus and Prospectus

for each series of iShares Trust and iShares, Inc.(each, a “Fund”)

The information in this Supplement updates information in, andshould be read in conjunction with, the Summary Prospectus,Prospectus and SAI for each Fund.

Effective immediately, each Fund’s Summary Prospectus andProspectus are amended as follows:

The following is added to the section of each Fund’s SummaryProspectus and Prospectus entitled “Summary of Principal Risks”:

Infectious Illness Risk. An outbreak of an infectious respiratory illness,COVID-19, caused by a novel coronavirus has resulted in travelrestrictions, disruption of healthcare systems, prolonged quarantines,cancellations, supply chain disruptions, lower consumer demand,layoffs, defaults and other significant economic impacts. Certainmarkets have experienced temporary closures, reduced liquidity andincreased trading costs. These events will have an impact on the Fundand its investments and could impact the Fund’s ability to purchase orsell securities or cause elevated tracking error and increased premiumsor discounts to the Fund’s net asset value. Other infectious illnessoutbreaks in the future may result in similar impacts.

The section of each Fund’s Summary Prospectus and Prospectusentitled “Summary of Principal Risks” is revised such that thefollowing is appended to the end of the paragraph entitled “MarketRisk”:

Local, regional or global events such as war, acts of terrorism, thespread of infectious illness or other public health issue, recessions, orother events could have a significant impact on the Fund and itsinvestments.

The section of each Fund’s Summary Prospectus and Prospectusentitled “Summary of Principal Risks” is revised such that the

following is appended to the end of the paragraph entitled “Index-Related Risk”:

Unusual market conditions may cause the Index Provider to postpone ascheduled rebalance, which could cause the Underlying Index to varyfrom its normal or expected composition.

The following is added to the section of each Fund’s Prospectusentitled “A Further Discussion of Principal Risks”:

Infectious Illness Risk. An outbreak of an infectious respiratory illness,COVID-19, caused by a novel coronavirus was first detected in China inDecember 2019 and has spread globally. This outbreak has resulted intravel restrictions, closed international borders, enhanced healthscreenings at ports of entry and elsewhere, disruption of and delays inhealthcare service preparation and delivery, prolonged quarantines,cancellations, supply chain disruptions, disruptions in markets, lowerconsumer demand, layoffs, defaults and other significant economicimpacts, as well as general concern and uncertainty. Disruptions inmarkets can adversely impact the Fund and its investments, includingimpairing hedging activity to the extent a Fund engages in such activity,as expected correlations between related markets or instruments mayno longer apply. In addition, to the extent the Fund invests in short-terminstruments that have negative yields, the Fund’s value may be impairedas a result. Further, certain local markets have been or may be subjectto closures, and there can be no assurance that trading will continue inany local markets in which the Fund may invest, when any resumptionof trading will occur or, once such markets resume trading, whetherthey will face further closures. Any suspension of trading in markets inwhich the Fund invests will have an impact on the Fund and itsinvestments and will impact the Fund’s ability to purchase or sellsecurities in such markets. Any market or economic disruption can beexpected to result in elevated tracking error and increased premiums ordiscounts to the Fund’s net asset value. The outbreak could also impairthe information technology and other operational systems upon whichthe Fund’s service providers, including BFA, rely, and could otherwisedisrupt the ability of employees of the Fund’s service providers toperform critical tasks relating to the Fund. The impact of this outbreakhas adversely affected the economies of many nations and the entireglobal economy and may impact individual issuers and capital marketsin ways that cannot be foreseen. In the past, governmental and quasi-governmental authorities and regulators throughout the world have attimes responded to major economic disruptions with a variety of fiscaland monetary policy changes, including direct capital infusions into

companies and other issuers, new monetary policy tools, and lowerinterest rates. An unexpected or sudden reversal of these policies, or theineffectiveness of such policies, is likely to increase market volatility,which could adversely affect the Fund’s investments. Other infectiousillness outbreaks that may arise in the future could have similar or otherunforeseen effects. Public health crises caused by the outbreak mayexacerbate other pre-existing political, social and economic risks incertain countries or globally. The duration of the outbreak and itseffects cannot be determined with certainty.

The section of each Fund’s Prospectus entitled “A Further Discussionof Principal Risks” is revised such that the last paragraph of thesection of each Fund’s Prospectus entitled “Index-Related Risk” isdeleted in its entirety and replaced with the following:

Unusual market conditions may cause the Index Provider to postpone ascheduled rebalance, which could cause the Underlying Index to vary fromits normal or expected composition. The postponement of a scheduledrebalance in a time of market volatility could mean that constituents thatwould otherwise be removed at rebalance due to changes in marketcapitalizations, issuer credit ratings, or other reasons may remain, causingthe performance and constituents of the Underlying Index to vary fromthose expected under normal conditions. Apart from scheduled rebalances,the Index Provider or its agents may carry out additional ad hoc rebalancesto the Underlying Index due to unusual market conditions or in order, forexample, to correct an error in the selection of index constituents. Whenthe Underlying Index is rebalanced and the Fund in turn rebalances itsportfolio to attempt to increase the correlation between the Fund’sportfolio and the Underlying Index, any transaction costs and marketexposure arising from such portfolio rebalancing will be borne directly bythe Fund and its shareholders. Therefore, errors and additional ad hocrebalances carried out by the Index Provider or its agents to the UnderlyingIndex may increase the costs to and the tracking error risk of the Fund.

The section of each Fund’s Prospectus entitled “A Further Discussionof Principal Risks” is revised such that the following is appended tothe end of the paragraph entitled “Market Risk”:

Local, regional or global events such as war, acts of terrorism, the spread ofinfectious illness or other public health issue, recessions, or other eventscould have a significant impact on the Fund and its investments.iShares® is a registered trademark of BlackRock Fund Advisors and its affiliates.

iSHARES® CURRENCY HEDGED MSCISOUTH KOREA ETF

Ticker: HEWY Stock Exchange: NYSE Arca

Investment ObjectiveThe iShares Currency Hedged MSCI South Korea ETF (the “Fund”) seeks to track theinvestment results of an index composed of large- and mid-capitalization South Koreanequities while mitigating exposure to fluctuations between the value of the SouthKorean won and the U.S. dollar.

Fees and ExpensesThe following table describes the fees and expenses that you will incur if you ownshares 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 the managementfees, interest expenses, taxes, expenses incurred with respect to the acquisition anddisposition of portfolio securities and the execution of portfolio transactions, includingbrokerage commissions, distribution fees or expenses, litigation expenses and anyextraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.”Acquired Fund Fees and Expenses reflect the Fund’s pro rata share of the fees andexpenses incurred by investing in other investment companies. The impact of AcquiredFund Fees and Expenses is included in the total returns of the Fund. Acquired FundFees and Expenses are not included in the calculation of the ratio of expenses toaverage net assets shown in the Financial Highlights section of the Fund’s prospectus(the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreedto waive a portion of its management fees so that the Fund’s total annual fundoperating expenses after this fee waiver is equal to the Acquired Fund Fees andExpenses attributable to the Fund’s investment in the iShares MSCI South Korea ETF(“EWY” or the “Underlying Fund”), after taking into account any fee waivers by EWY,plus 0.03% through December 31, 2020. The contractual waiver may be terminatedprior to December 31, 2020 only upon written agreement of the Trust and BFA. BFAhas contractually agreed to waive its management fees by an additional amount equalto 0.03% through December 31, 2020. The contractual waiver may be terminated priorto December 31, 2020 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions and other chargeswhen buying or selling shares of the Fund, which are not reflected in the Example thatfollows:

Example. This Example is intended to help you compare the cost of owning shares ofthe Fund with the cost of investing in other funds. The Example assumes that youinvest $10,000 in the Fund for the time periods indicated and then sell all of yourshares at the end of those periods. The Example also assumes that your investmenthas 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, yourcosts would be:

1 Year 3 Years 5 Years 10 Years

$60 $354 $670 $1567

Portfolio Turnover. The Fund and theUnderlying Fund in which the Fundprincipally invests, the iShares MSCISouth Korea ETF, may pay transactioncosts, such as commissions, when theybuy and sell securities (or “turn over”their portfolios). A higher portfolioturnover rate for the Fund or theUnderlying Fund may indicate highertransaction costs and may cause theFund or the Underlying Fund to incurincreased expenses. These costs, whichare not reflected in the Annual FundOperating Expenses or in theExample (except costs to the UnderlyingFund included as part of Acquired FundFees and Expenses), affect the Fund’sperformance. During the most recentfiscal year, the Fund’s portfolio turnoverrate was 17% of the average value of itsportfolio. To the extent the UnderlyingFund incurs costs from high portfolioturnover, such costs may have anegative effect on the performance ofthe Fund.

Principal InvestmentStrategiesThe Fund seeks to track the investmentresults of the MSCI Korea 25/50 100%Hedged to USD Index (the “UnderlyingIndex”), which primarily consists ofstocks traded on the Stock MarketDivision of the Korea Exchange with thecurrency risk inherent in the securitiesincluded in the Underlying Index hedgedto the U.S. dollar on a monthly basis.The Underlying Index is a free float-adjusted market capitalization-weightedindex with a capping methodologyapplied to issuer weights so that nosingle issuer exceeds 25% of theUnderlying Index weight, and all issuerswith a weight above 5% do notcumulatively exceed 50% of theUnderlying Index weight. The UnderlyingIndex will include large- and mid-capitalization companies and maychange over time. As of August 31,2019, a significant portion of theUnderlying Index is represented bysecurities of companies in the

S-2

information technology industry orsector. The components of theUnderlying Index are likely to changeover time.

Currently, the Fund achieves itsinvestment objective by investing asubstantial portion of its assets in theUnderlying Fund.

BFA uses a “passive” or indexingapproach to try to achieve the Fund’sinvestment objective. Unlike manyinvestment companies, the Fund doesnot try to “beat” the index it tracks anddoes not seek temporary defensivepositions when markets decline orappear overvalued.

Indexing may eliminate the chance thatthe Fund will substantially outperformthe Underlying Index but also mayreduce some of the risks of activemanagement, such as poor securityselection. Indexing seeks to achievelower costs and better after-taxperformance by aiming to keep portfolioturnover low in comparison to activelymanaged investment companies.

BFA uses a representative samplingindexing strategy to manage the Fundand the Underlying Fund.“Representative sampling” is anindexing strategy that involves investingin a representative sample of securitiesor other instruments comprising anapplicable underlying index. Thesecurities selected are expected tohave, in the aggregate, investmentcharacteristics (based on factors suchas market capitalization and industryweightings), fundamentalcharacteristics (such as returnvariability and yield) and liquiditymeasures similar to those of anapplicable underlying index. The Fundand the Underlying Fund may or maynot hold all of the securities and other

components of the applicableunderlying index.

The Fund generally will invest at least90% of its assets in the componentsecurities (including indirectinvestments through the UnderlyingFund) and other instruments of theUnderlying Index and in investmentsthat have economic characteristics thatare substantially identical to thecomponent securities of the UnderlyingIndex (i.e., depositary receiptsrepresenting securities of theUnderlying Index) and may invest up to10% of its assets in certain futures,options and swap contracts, cash andcash equivalents, including shares ofmoney market funds advised by BFA orits affiliates, as well as in securities notincluded in the Underlying Index, butwhich BFA believes will help the Fundtrack the Underlying Index. Componentsof the Underlying Index include equitysecurities and foreign currency forwardcontracts (both deliverable and non-deliverable) designed to hedge non-U.S.currency fluctuations against the U.S.dollar. The notional exposure to foreigncurrency forward contracts (bothdeliverable and non-deliverable)generally will be a short position thathedges the currency risk of the equityportfolio. The Fund seeks to track theinvestment results of the UnderlyingIndex before fees and expenses of theFund.

The Underlying Index sells forward thetotal value of the non-U.S. dollardenominated securities included in theUnderlying Index at a one-monthforward rate to effectively create a“hedge” against fluctuations in therelative value of the South Korean wonin relation to the U.S. dollar. The hedgeis reset on a monthly basis. TheUnderlying Index is designed to have

S-3

higher returns than an equivalentunhedged investment when the SouthKorean won is weakening relative to theU.S. dollar. Conversely, the UnderlyingIndex is designed to have lower returnsthan an equivalent unhedgedinvestment when the South Korean wonis rising relative to the U.S. dollar.

In order to track the “hedging”component of the Underlying Index, theFund intends to enter into foreigncurrency forward contracts designed tooffset the Fund’s exposure to the SouthKorean won. A foreign currency forwardcontract is a contract between twoparties to buy or sell a specified amountof a specific currency in the future at anagreed-upon exchange rate. The Fund’sexposure to foreign currency forwardcontracts is based on the aggregateexposure of the Fund to the SouthKorean won. While this approach isdesigned to minimize the impact ofcurrency fluctuations on Fund returns, itdoes not necessarily eliminate theFund’s exposure to the South Koreanwon. The return of the foreign currencyforward contracts may not perfectlyoffset the actual fluctuations in valuebetween the South Korean won and theU.S. dollar.

The Fund may also use non-deliverableforward (“NDF”) contracts to execute itshedging transactions. An NDF is acontract where there is no physicalsettlement of two currencies atmaturity. Rather, based on themovement of the currencies and thecontractually agreed-upon exchangerate, a net cash settlement will be madeby one party to the other in U.S. dollars.

The Fund may lend securitiesrepresenting up to one-third of thevalue of the Fund’s total assets(including the value of any collateralreceived).

The Underlying Index is sponsored byMSCI Inc. (the “Index Provider” or“MSCI”), which is independent of theFund and BFA. The Index Providerdetermines the composition and relativeweightings of the securities andcurrency forwards in the UnderlyingIndex and publishes informationregarding the market value of theUnderlying Index.

Industry Concentration Policy. TheFund will concentrate its investments(i.e., hold 25% or more of its totalassets) in a particular industry or groupof industries to approximately the sameextent that the Underlying Index isconcentrated. For purposes of thislimitation, securities of the U.S.government (including its agencies andinstrumentalities) and repurchaseagreements collateralized by U.S.government securities are notconsidered to be issued by members ofany industry.

Summary of Principal RisksAs with any investment, you could loseall or part of your investment in theFund, and the Fund’s performance couldtrail that of other investments. The Fundis subject to certain risks, including theprincipal risks noted below (eitherdirectly or through its investments inthe Underlying Fund), any of which mayadversely affect the Fund’s net assetvalue per share (“NAV”), trading price,yield, total return and ability to meet itsinvestment objective. The order of thebelow risk factors does not indicate thesignificance of any particular risk factor.

Asset Class Risk. Securities and otherassets in the Underlying Index or in theFund’s or the Underlying Fund’sportfolio may underperform incomparison to the general financial

S-4

markets, a particular financial market orother asset classes.

Assets Under Management (AUM)Risk. From time to time, an AuthorizedParticipant (as defined in the Creationsand Redemptions section of thisProspectus), a third-party investor, theFund’s adviser or an affiliate of theFund’s adviser, or a fund may invest inthe Fund and hold its investment for aspecific period of time to allow the Fundto achieve size or scale. There can beno assurance that any such entity wouldnot redeem its investment or that thesize of the Fund would be maintained atsuch levels, which could negativelyimpact the Fund.

Authorized Participant ConcentrationRisk. Only an Authorized Participantmay engage in creation or redemptiontransactions directly with the Fund, andnone of those Authorized Participants isobligated to engage in creation and/orredemption transactions. The Fund hasa limited number of institutions thatmay act as Authorized Participants onan agency basis (i.e., on behalf of othermarket participants). To the extent thatAuthorized Participants exit thebusiness or are unable to proceed withcreation or redemption orders withrespect to the Fund and no otherAuthorized Participant is able to stepforward to create or redeem CreationUnits (as defined in the Purchase andSale of Fund Shares section of theProspectus), Fund shares may be morelikely to trade at a premium or discountto NAV and possibly face trading haltsor delisting. Authorized Participantconcentration risk may be heightenedfor exchange-traded funds (“ETFs”),such as the Fund, that invest insecurities issued by non-U.S. issuers orother securities or instruments thathave lower trading volumes.

Concentration Risk. The Fund may besusceptible to an increased risk of loss,including losses due to adverse eventsthat affect the Fund’s investments morethan the market as a whole, to theextent that the Fund’s or the UnderlyingFund’s investments are concentrated inthe securities and/or other assets of aparticular issuer or issuers, country,group of countries, region, market,industry, group of industries, sector orasset class.

Currency Hedging Risk. In seeking totrack the “hedging” component of theUnderlying Index, the Fund invests incurrency forward contracts (which mayinclude both physically-settled forwardcontracts and NDFs) designed to hedgethe currency exposure of non-U.S.dollar denominated securities held in itsportfolio (directly or indirectly throughits investment in the Underlying Fund).While hedging can reduce or eliminatelosses, it can also reduce or eliminategains. Hedges are sometimes subject toimperfect matching between thederivative and its reference asset, andthere can be no assurance that theFund’s hedging transactions will beeffective.

Exchange rates may be volatile and maychange quickly and unpredictably inresponse to both global economicdevelopments and economic conditionsin a geographic region in which theFund or the Underlying Fund invests. Inaddition, in order to minimizetransaction costs, or for other reasons,the Fund’s exposure to the SouthKorean won may not be fully hedged atall times. Because currency forwardsare over-the-counter instruments, theFund is subject to counterparty risk aswell as market or liquidity risk withrespect to the hedging transactions theFund enters into.

S-5

The effectiveness of the Fund’s currencyhedging strategy will in general beaffected by the volatility of both theUnderlying Index and the volatility of theU.S. dollar relative to the South Koreanwon, measured on an aggregate basis.Increased volatility in either or both ofthe Underlying Index and the U.S. dollarrelative to the South Korean won willgenerally reduce the effectiveness ofthe Fund’s currency hedging strategy.The effectiveness of the Fund’s currencyhedging strategy may also in general beaffected by interest rates. Significantdifferences between U.S. dollar interestrates and foreign currency interestrates applicable to the South Koreanwon may impact the effectiveness ofthe Fund’s currency hedging strategy.

Currency Risk. Because the Fund’s andthe Underlying Fund’s NAVs aredetermined in U.S. dollars, the Fund’sNAV could decline if the South Koreanwon depreciates against the U.S. dollarand/or the Fund’s attempt to hedgecurrency exposure to the South Koreanwon is unsuccessful. Generally, anincrease in the value of the U.S. dollaragainst the South Korean won willreduce the value of a securitydenominated in the South Korean won.In addition, fluctuations in the exchangerates of currencies could affect theeconomy or particular businessoperations of companies in ageographic region, including securitiesin which the Fund or the UnderlyingFund invests, causing an adverseimpact on the Fund’s or the UnderlyingFund’s investments in the affectedregion and the U.S. As a result,investors have the potential for lossesregardless of the length of time theyintend to hold Fund shares. Currencyexchange rates can be very volatile andcan change quickly and unpredictably.

As a result, the Fund’s NAV may changequickly and without warning.

Custody Risk. Less developedsecurities markets are more likely thanmore developed securities markets toexperience problems with the clearingand settling of trades, as well as theholding of securities by local banks,agents and depositories.

Cybersecurity Risk. Failures orbreaches of the electronic systems ofthe Fund or the Underlying Fund, theFund’s or the Underlying Fund’s adviser,distributor, the Index Provider and otherservice providers, market makers,Authorized Participants, hedgingcounterparties to the Fund or theissuers of securities in which the Fundor the Underlying Fund invests have theability to cause disruptions, negativelyimpact the Fund’s business operationsand/or potentially result in financiallosses to the Fund and its shareholders.While the Fund has established businesscontinuity plans and risk managementsystems seeking to address systembreaches or failures, there are inherentlimitations in such plans and systems.Furthermore, the Fund cannot controlthe cybersecurity plans and systems ofthe Fund’s Index Provider and otherservice providers, market makers,Authorized Participants, hedgingcounterparties to the Fund or issuers ofsecurities in which the Fund or theUnderlying Fund invests.

Derivatives Risk. The Fund will usecurrency forwards and NDFs to hedgethe currency exposure resulting frominvestments in the foreign currency-denominated securities held by theFund or the Underlying Fund. TheFund’s or the Underlying Fund’s use ofthese instruments, like investments inother derivatives, may reduce the

S-6

Fund’s or the Underlying Fund’s returns,increase volatility and/or result inlosses due to credit risk or ineffectivehedging strategies. Volatility is definedas the characteristic of a security, acurrency, an index or a market, tofluctuate significantly in price within adefined time period. Currency forwards,like other derivatives, are also subjectto counterparty risk, which is the riskthat the other party in the transactionwill not fulfill its contractual obligation.

A risk of the Fund’s or the UnderlyingFund’s use of derivatives is that thefluctuations in their values may notcorrelate perfectly with the value of theSouth Korean won as compared to thatof the U.S. dollar. The possible lack of aliquid secondary market for derivativesand the resulting inability of the Fund orthe Underlying Fund to sell or otherwiseclose a derivatives position couldexpose the Fund or the Underlying Fundto losses and could make derivativesmore difficult for the Fund or theUnderlying Fund to value accurately.The Fund or the Underlying Fund couldalso suffer losses related to itsderivatives positions as a result ofunanticipated market movements,which losses are potentially unlimited.BFA’s use of derivatives is not intendedto predict the direction of securitiesprices, currency exchange rates,interest rates and other economicfactors, which could cause the Fund’sderivatives positions to lose value.Derivatives may give rise to a form ofleverage and may expose the Fund orthe Underlying Fund to greater risk andincrease its costs. Regulatoryrequirements may make derivativesmore costly, may limit the availability ofderivatives, and may delay or restrictthe exercise of remedies by the Fundupon a counterparty default under

derivatives held by the Fund (whichcould result in losses), remedies ortermination rights by the Fund, and mayotherwise adversely affect the value andperformance of derivatives.

Equity Securities Risk. Equitysecurities are subject to changes invalue, and their values may be morevolatile than those of other assetclasses. The Underlying Index iscomprised of common stocks, whichgenerally subject their holders to morerisks than preferred stocks and debtsecurities because commonstockholders’ claims are subordinatedto those of holders of preferred stocksand debt securities upon the bankruptcyof the issuer.

Geographic Risk. A natural disastercould occur in South Korea, which couldadversely affect the economy or thebusiness operations of companies inSouth Korea, causing an adverse impacton the Fund’s or the Underlying Fund’sinvestments in South Korea.

Index-Related Risk. There is noguarantee that the Fund’s investmentresults will have a high degree ofcorrelation to those of the UnderlyingIndex or that the Fund will achieve itsinvestment objective. Marketdisruptions and regulatory restrictionscould have an adverse effect on theFund’s ability to adjust its exposure tothe required levels in order to track theUnderlying Index. Errors in index data,index computations or the constructionof the Underlying Index in accordancewith its methodology may occur fromtime to time and may not be identifiedand corrected by the Index Provider fora period of time or at all, which mayhave an adverse impact on the Fundand its shareholders.

S-7

Information Technology Sector Risk.Information technology companies faceintense competition and potentiallyrapid product obsolescence. They arealso heavily dependent on intellectualproperty rights and may be adverselyaffected by the loss or impairment ofthose rights. Companies in theinformation technology sector arefacing increased government andregulatory scrutiny and may be subjectto adverse government or regulatoryaction. Companies in the softwareindustry may be adversely affected by,among other things, the decline orfluctuation of subscription renewal ratesfor their products and services andactual or perceived vulnerabilities intheir products or services.

Investment in Underlying Fund Risk.The Fund invests a substantial portionof its assets in the Underlying Fund, sothe Fund’s investment performance islikely to be directly related to theperformance of the Underlying Fund.The Fund’s NAV will change withchanges in the value of the UnderlyingFund and other instruments in which theFund invests based on their marketvaluations. An investment in the Fundwill entail more costs and expensesthan a direct investment in theUnderlying Fund, including as a result ofthe currency hedging activity conductedby the Fund.

As the Fund’s allocation to theUnderlying Fund changes from time totime, or to the extent that the totalannual fund operating expenses of theUnderlying Fund changes, the weightedaverage operating expenses borne bythe Fund may increase or decrease.

Issuer Risk. The performance of theFund depends on the performance ofindividual securities and other

instruments to which the Fund and theUnderlying Fund have exposure.Changes in the financial condition orcredit rating of an issuer of thosesecurities or counterparty on otherinstruments may cause the value of thesecurities or instruments to decline.

Large-Capitalization Companies Risk.Large-capitalization companies may beless able than smaller capitalizationcompanies to adapt to changing marketconditions. Large-capitalizationcompanies may be more mature andsubject to more limited growth potentialcompared with smaller capitalizationcompanies. During different marketcycles, the performance of large-capitalization companies has trailed theoverall performance of the broadersecurities markets.

Management Risk. As the Fund will notfully replicate the Underlying Index, it issubject to the risk that BFA’sinvestment strategy may not producethe intended results.

Market Risk. The Fund and theUnderlying Fund could lose money overshort periods due to short-term marketmovements and over longer periodsduring more prolonged marketdownturns. Local, regional or globalevents such as war, acts of terrorism,the spread of infectious illness or otherpublic health issue, recessions, or otherevents could have a significant impacton the Fund and its investments.

Market Trading Risk. The Fund and theUnderlying Fund face numerous markettrading risks, including the potentiallack of an active market for their shares,losses from trading in secondarymarkets, losses due to ineffectivecurrency hedges, periods of highvolatility and disruptions in thecreation/redemption process. ANY OF

S-8

THESE FACTORS, AMONG OTHERS,MAY LEAD TO THE FUND’S AND THEUNDERLYING FUND’S SHARESTRADING AT A PREMIUM ORDISCOUNT TO NAV.

National Closed Market Trading Risk.To the extent that the underlyingsecurities and/or other assets held bythe Fund or the Underlying Fund tradeon foreign exchanges or in foreignmarkets that may be closed when thesecurities exchange on which theFund’s or the Underlying Fund’s sharestrade is open, there are likely to bedeviations between the current price ofsuch an underlying security and the lastquoted price for the underlying security(i.e., the Fund’s or the Underlying Fund’squote from the closed foreign market).These deviations could result inpremiums or discounts to the Fund’s orthe Underlying Fund’s NAV that may begreater than those experienced by otherETFs.

Non-U.S. Securities Risk. Investmentsin the securities of non-U.S. issuers aresubject to the risks associated withinvesting in those non-U.S. markets,such as heightened risks of inflation ornationalization. The Fund or theUnderlying Fund may lose money due topolitical, economic and geographicevents affecting issuers of SouthKorean securities or South Koreanmarkets. In addition, non-U.S. securitiesmarkets may trade a small number ofsecurities and may be unable torespond effectively to changes intrading volume, potentially makingprompt liquidation of holdings difficultor impossible at times. The Fund andthe Underlying Fund are specificallyexposed to Asian Economic Risk.

Operational Risk. The Fund and theUnderlying Fund are exposed to

operational risks arising from a numberof factors, including, but not limited to,human error, processing andcommunication errors, errors of theFund’s or the Underlying Fund’s serviceproviders, counterparties or other third-parties, failed or inadequate processesand technology or systems failures. TheFund, the Underlying Fund and BFA seekto reduce these operational risksthrough controls and procedures.However, these measures do notaddress every possible risk and may beinadequate to address significantoperational risks.

Passive Investment Risk. The Fund andthe Underlying Fund are not activelymanaged, and BFA generally does notattempt to take defensive positionsunder any market conditions, includingdeclining markets.

Privatization Risk. The country in whichthe Fund or the Underlying Fund investshas privatized, or has begun the processof privatizing, certain entities andindustries. Privatized entities may losemoney or be re-nationalized.

Reliance on Trading Partners Risk.The Fund and the Underlying Fundinvest in a country whose economy isheavily dependent upon trading with keypartners. Any reduction in this tradingmay have an adverse impact on theFund’s investments. Through itsholdings of securities of certain issuers,the Fund and the Underlying Fund arespecifically exposed to AsianEconomic Risk and U.S. EconomicRisk.

Risk of Investing in EmergingMarkets. The Fund’s or the UnderlyingFund’s investments in emerging marketissuers may be subject to a greater riskof loss than investments in issuerslocated or operating in more developed

S-9

markets. Emerging markets may bemore likely to experience inflation,political turmoil and rapid changes ineconomic conditions than moredeveloped markets. Emerging marketsoften have less uniformity in accountingand reporting requirements, lessreliable securities valuations andgreater risk associated with custody ofsecurities than developed markets.

Risk of Investing in South Korea.Investments in South Korean issuersmay subject the Fund and theUnderlying Fund to legal, regulatory,political, currency, security, andeconomic risks that are specific toSouth Korea. In addition, economic andpolitical developments of South Korea’sneighbors, including escalated tensionsinvolving North Korea and any outbreakof hostilities involving North Korea, oreven the threat of an outbreak ofhostilities, may have a severe adverseeffect on the South Korean economy.

Securities Lending Risk. The Fund andthe Underlying Fund may engage insecurities lending. Securities lendinginvolves the risk that the Fund or theUnderlying Fund may lose moneybecause the borrower of the loanedsecurities fails to return the securities ina timely manner or at all. The Fund orthe Underlying Fund could also losemoney in the event of a decline in thevalue of collateral provided for loanedsecurities or a decline in the value ofany investments made with cashcollateral. These events could alsotrigger adverse tax consequences forthe Fund.

Security Risk. The geographic area inwhich the Fund and the Underlying Fundinvest has experienced securityconcerns, such as terrorism andstrained international relations.

Incidents involving a country’s orregion’s security may cause uncertaintyin its markets and may adversely affectits economy and the Fund’s or theUnderlying Fund’s investments.

Small Fund Risk. When the Fund’s sizeis small, the Fund may experience lowtrading volume and wide bid/askspreads. In addition, the Fund may facethe risk of being delisted if the Funddoes not meet certain conditions of thelisting exchange. Any resultingliquidation of the Fund could cause theFund to incur elevated transaction costsfor the Fund and negative taxconsequences for its shareholders.

Tax Risk. Because the Fund invests inthe Underlying Fund, the Fund’s realizedlosses on sales of shares of theUnderlying Fund may be indefinitely orpermanently deferred as “wash sales.”Distributions of short-term capital gainsby the Underlying Fund will berecognized as ordinary income by theFund and would not be offset by theFund’s capital loss carryforwards, if any.Capital loss carryforwards of theUnderlying Fund, if any, would not offsetnet capital gains of the Fund. Each ofthese effects is caused by the Fund’sinvestment in the Underlying Fund andmay result in distributions to Fundshareholders being of higher magnitudeand less likely to qualify for lowercapital gain tax rates than if the Fundwere to invest directly in the securitiesand other instruments comprising theUnderlying Index. The Fund invests inderivatives. The federal income taxtreatment of a derivative may not be asfavorable as a direct investment in anunderlying asset. Derivatives mayproduce taxable income and taxablerealized gain. Derivatives may adverselyaffect the timing, character and amountof income the Fund realizes from its

S-10

investments. As a result, a largerportion of the Fund’s distributions maybe treated as ordinary income ratherthan as capital gains. In addition,certain derivatives are subject to mark-to-market or straddle provisions of theInternal Revenue Code of 1986, asamended (the “Internal Revenue Code”).If such provisions are applicable, therecould be an increase (or decrease) inthe amount of taxable dividends paid bythe Fund. Income from swaps isgenerally taxable. In addition, the taxtreatment of certain derivatives, such asswaps, is unsettled and may be subjectto future legislation, regulation oradministrative pronouncements issuedby the U.S. Internal Revenue Service(“IRS”).

Tracking Error Risk. The Fund may besubject to tracking error, which is thedivergence of the Fund’s performancefrom that of the Underlying Index.Tracking error may occur because ofdifferences between thesecurities (including shares of theUnderlying Fund) and other instrumentsheld in the Fund’s portfolio and thoseincluded in the Underlying Index, pricingdifferences (including, as applicable,differences between a security’s priceat the local market close and the Fund’svaluation of a security at the time ofcalculation of the Fund’s NAV),transaction and hedging costs incurredand forward rates achieved by the Fund,the Fund’s holding of uninvested cash,differences in timing of the accrual of orthe valuation of dividends or otherdistributions, interest, the requirementsto maintain pass-through tax treatment,portfolio transactions carried out tominimize the distribution of capitalgains to shareholders, changes to theUnderlying Index and the cost to theFund of complying with various new or

existing regulatory requirements. Theserisks may be heightened during times ofincreased market volatility or otherunusual market conditions in theaffected securities and/or foreignexchange markets. In addition, trackingerror may result because the Fundincurs fees and expenses, while theUnderlying Index does not, and becausethe Fund accepts creations andredemptions during time periodsbetween which it is able to adjust itscurrency hedges, whereas theUnderlying Index does not adjust itshedging during these periods. To theextent that the Fund seeks itsinvestment objective throughinvestments in the Underlying Fund, theFund may experience increasedtracking error as compared to investingdirectly in the component securities ofthe Underlying Index. The potential forincreased tracking error may result frominvestments in the Underlying Fund dueto, among other things, differences inthe composition of the investmentportfolio of the Underlying Fund ascompared to the index tracked by theUnderlying Fund and differences in thetiming of the Fund’s valuation of: (i) theUnderlying Fund and the currencyforward contracts (each valued as of theclose of the New York Stock Exchange(“NYSE”), typically 4:00 p.m., EasternTime), (ii) the valuation of the securitiesin the Underlying Index (generallyvalued as of each security’s localmarket close) and (iii) the currencyforward contracts included in theUnderlying Index (generally valued at4:00 p.m., London time). INDEX ETFsTHAT TRACK INDICES WITHSIGNIFICANT WEIGHT IN EMERGINGMARKETS ISSUERS MAY EXPERIENCEHIGHER TRACKING ERROR THANOTHER INDEX ETFs THAT DO NOTTRACK SUCH INDICES.

S-11

Valuation Risk. The price the Fund andthe Underlying Fund could receive uponthe sale of a security or unwind of afinancial instrument or other asset maydiffer from the Fund’s or the UnderlyingFund’s valuation of the security,instrument or other asset and from thevalue used by the Underlying Index,particularly for securities or otherinstruments that trade in low volume orvolatile markets or that are valued usinga fair value methodology as a result oftrade suspensions or for other reasons.In addition, the value of the securities orother instruments in the Fund’s or theUnderlying Fund’s portfolio may changeon days or during time periods whenshareholders will not be able to

purchase or sell the Fund’s or theUnderlying Fund’s shares. AuthorizedParticipants who purchase or redeemFund shares on days when the Fund orthe Underlying Fund is holding fair-valued securities may receive fewer ormore shares, or lower or higherredemption proceeds, than they wouldhave received had the Fund or theUnderlying Fund not fair-valuedsecurities or used a different valuationmethodology. The Fund’s or theUnderlying Fund’s ability to valueinvestments may be impacted bytechnological issues or errors by pricingservices or other third-party serviceproviders.
