Fees and Expenses

Expense Narrative [Text Block]

rr_ExpenseNarrativeTextBlock

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, Inc. (the “Company”) 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, distribution fees or expenses, (v) litigation expenses, and (vi) any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after fee waiver is equal to the Acquired Fund Fees and Expenses attributable to the Fund's investment in the iShares MSCI Emerging Markets ETF (“EEM” or the “Underlying Fund”), after taking into account any fee waivers by EEM through December 31, 2025. The contractual waiver may be terminated prior to December 31, 2025 only upon written agreement of the Company and BFA.

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

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to track the investment results of the MSCI Emerging Markets 100% Hedged to USD Index (the “Underlying Index”), which has been developed by MSCI Inc. (the “Index Provider” or “MSCI”) as an equity

benchmark for global emerging markets stock performance with the currency risk inherent in the securities included in the Underlying Index hedged to the U.S. dollar on a monthly basis. As of August 31, 2021, the Underlying Index consisted of securities from the following 27 emerging market countries: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Kuwait, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, Saudi Arabia, South Africa, South Korea, Taiwan, Thailand, Turkey and the United Arab Emirates. The Underlying Index includes large- and mid-capitalization companies and may change over time. As of August 31, 2021, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary, financials and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

Currently, the Fund achieves its investment objective by investing a substantial portion of its assets in the Underlying Fund.

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 and the Underlying 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 capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund and the Underlying Fund may or may not hold all of the securities and other components of the applicable underlying index.

The Fund generally will invest at least 80% of its assets in the component securities (including indirect investments through the Underlying Fund) and other instruments of its Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to

20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Components of the Underlying Index may include equity securities and foreign currency forward contracts (both deliverable and non-deliverable) designed to hedge against non-U.S. currency fluctuations against the U.S. dollar. The notional exposure of foreign currency forward contracts (both deliverable and non-deliverable) generally will be a short position that hedges currency risk of the equity portfolio. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating investments not included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Underlying Index sells forward the total value of the non-U.S. dollar denominated securities included in the Underlying Index at a one-month forward rate to effectively create a “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 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 are rising relative to the U.S. dollar.

In order to track the “hedging” component of the Underlying Index, the Fund intends to enter 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 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 Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

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

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

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

Risk [Heading]

Summary of Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Underlying Fund), 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 or the Underlying 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 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.

Commodity Risk. The Fund and the Underlying Fund may invest 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, regulatory developments, other catastrophic events, or other factors that the Fund cannot control could have an adverse impact on those companies.

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 or the Underlying 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, sector, market segment or asset class.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and

interest rates, competition, consumers' disposable income, consumer preferences, social trends and marketing campaigns.

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 contracts and NDFs) designed to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio (directly or indirectly through its investment in the Underlying Fund). 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 or the Underlying 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. In addition, each currency's hedge is reset on a monthly basis and will not be adjusted during the month based on movement in the value of the component securities or currencies. As a result, the Underlying Index may be “over-hedged” or “under-hedged” between month-end rebalances. 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 and the Underlying Fund's NAVs are determined in U.S. dollars, the Fund's NAV could decline if the currency of one or more of the non-U.S. markets in which the Fund or the Underlying 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 of currencies could affect the economy or particular business operations of companies in a geographic region, including securities in which the Fund or the Underlying Fund invests, causing an adverse impact on the Fund’s or the Underlying 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 than more developed securities markets to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Fund, the Fund's or the Underlying Fund's adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of securities in which the Fund

or the Underlying 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, hedging counterparties to the Fund or issuers of securities in which the Fund or the Underlying 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 or the Underlying Fund. The Fund’s or the Underlying Fund's use of these instruments, like investments in other derivatives, may reduce the Fund’s or the Underlying 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 or the Underlying 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 or the Underlying Fund to sell or otherwise close a derivatives position could expose the Fund or the Underlying Fund to losses and could make derivatives more difficult for the Fund or the Underlying Fund to value accurately. The Fund or the Underlying 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 or the Underlying 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.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The Underlying Index is composed of common stocks, which generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, and decreased liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or the Underlying 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 or the Underlying Fund's investments in, or which are exposed to, the affected region.

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 may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Infectious Illness Risk. An outbreak of an infectious respiratory illness, COVID-19, caused by a novel coronavirus has resulted in travel restrictions, disruption

of healthcare systems, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic impacts. Certain markets have experienced temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. These events will have an impact on the Fund and its investments and could 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. Other infectious illness outbreaks in the future may result in similar impacts.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Companies in the software industry may be adversely affected by, among other things, the decline or

fluctuation of subscription renewal rates for their products and services and actual or perceived vulnerabilities in their products or services.

Investment in Underlying Fund Risk. The Fund invests a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance is likely to be directly related to the performance of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other instruments in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Fund, including as a result of the currency hedging activity conducted by the Fund.

As the Fund’s allocation to the Underlying Fund changes from time to time, or to the extent that the total annual fund operating expenses of the Underlying Fund change, the weighted average operating expenses borne by the Fund may increase or decrease.

Issuer Risk. The performance of the Fund depends on the performance of individual securities and other instruments to which the Fund and the Underlying Fund have exposure. Changes in the financial condition or credit rating of an issuer of those securities or counterparty on other instruments may cause the value of the securities or instruments to decline.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

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 and the Underlying 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 and the Underlying Fund face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, losses due to ineffective currency hedges, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S AND THE UNDERLYING FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

National Closed Market Trading Risk. To the extent that the underlying securities and/or other assets held by the Fund or the Underlying Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or the Underlying Fund's shares trade is

open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or the Underlying Fund's quote from the closed foreign market). The impact of a closed foreign market on the Fund or the Underlying Fund is likely to be greater where a large portion of the Fund’s or the Underlying Fund's underlying securities and/or other assets trade on that closed foreign market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or the Underlying Fund's NAV that may be greater than those experienced by other ETFs.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund or the Underlying Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets 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. The Fund and the Underlying Fund are specifically exposed to Asian Economic Risk.

Operational Risk. The Fund and the Underlying Fund are 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 or the Underlying Fund's service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying 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 and the Underlying Fund are 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 or the Underlying 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 and the Underlying Fund invest 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 and the Underlying Fund are specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time

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

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, 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.

Many Chinese companies listed on U.S. exchanges use variable interest entities or “VIEs” in their structure as a result of foreign ownership restrictions. In a VIE structure, a Chinese operating company establishes a shell company in another jurisdiction to issue stock to public shareholders. When a VIE structure is used by a Chinese company to list its stock in the U.S., instead of owning the equity securities of the Chinese company, the U.S.-listed shell company directly or indirectly enters into contracts with the Chinese operating company under Chinese law. These contracts provide the U.S.-listed shell company with only economic exposure to the Chinese company. Intervention by the Chinese government with respect to VIE structures or the non-enforcement of VIE-related contractual rights could significantly affect the operating company’s business in China, the enforceability of the U.S.-listed shell company’s contractual arrangements with the Chinese company and the value of the U.S.-listed stock. Any change in the operations of entities in a VIE structure, the status of VIE contractual arrangements or the legal or regulatory environment in China could result in significant losses to the Fund.

Chinese companies, including Chinese companies that are listed on U.S.

exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and 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 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, political turmoil and 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. A number of jurisdictions, including the U.S., Canada and the European Union (the “EU”), have imposed economic sanctions on certain Russian individuals and Russian corporate entities. Additionally, Russia is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Russian government or Russian companies, may impact Russia’s economy and Russian issuers of securities in which the Fund invests.

Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fund or an Underlying 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. The economy of Saudi Arabia is dominated by petroleum exports. A

sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries 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 decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. There remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.

Saudi Arabia Broker Risk. There are a number of different ways of conducting transactions in equity securities in the Saudi Arabian market. The Fund (or an Underlying Fund) generally expects to conduct its transactions in a manner in which the Fund would not be limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund (or an Underlying Fund), which may have an adverse impact on the prices, quantity or timing of Fund (or an Underlying Fund) transactions.

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

Security Risk. Some countries and regions in which the Fund and the

Underlying Fund invest have experienced security concerns, such as 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 or the Underlying Fund's investments.

Structural Risk. The countries in which the Fund or the Underlying Fund invests may be subject to considerable degrees of economic, political and social instability.

Tax Risk. Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund's investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund

were to invest directly in the securities and other instruments composing the Underlying Index. 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”).

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 (including shares of the Underlying Fund) 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, interest, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, 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. Tracking error may occur due to differences between the methodologies used in calculating the index value and determining the Fund's NAV. To the extent that the Fund seeks its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the component securities of the Underlying Index. The potential for increased tracking error may result from investments in the Underlying Fund due to, among other things, differences in the composition of the investment portfolio of the Underlying Fund as compared to the index tracked by the Underlying Fund and differences in the timing of the Fund’s valuation of: (i) the

Underlying Fund and the currency forward contracts (each valued as of the close of the New York Stock Exchange (“NYSE”), typically 4:00 p.m., Eastern Time), (ii) the valuation of the securities in the Underlying Index (generally valued as of each security’s local market close) and (iii) the currency forward contracts included in the Underlying Index (generally valued at 4:00 p.m., London time). INDEX ETFs THAT TRACK INDICES WITH SIGNIFICANT WEIGHT IN EMERGING MARKETS ISSUERS MAY EXPERIENCE HIGHER TRACKING ERROR THAN OTHER INDEX ETFs THAT DO NOT TRACK SUCH INDICES.

Valuation Risk. The price the Fund and the Underlying Fund could receive upon the sale of a security or unwind of a financial instrument or other asset may differ from the Fund's or the Underlying 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. In addition, the value of the securities or other instruments in the Fund's or the Underlying Fund's portfolio may change on days or during time periods when

shareholders will not be able to purchase or sell the Fund's or the Underlying Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund or the Underlying 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 Fund or the Underlying Fund not fair-valued securities or used a different valuation methodology. The Fund’s or the Underlying Fund's ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

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”).

Performance Table Explanation after Tax Higher

rr_PerformanceTableExplanationAfterTaxHigher

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.
