iShares MSCI South Korea ETF (EWY) Exchange: NYSE ARCA

The Fund seeks to track the investment results of the MSCI Korea 25/50 Index (the “Underlying Index”), which primarily consists of stocks traded on the Stock Market Division of the Korea Exchange. The Underlying Index is a free float-adjusted market capitalization-weighted index with a capping methodology applied to issuer weights so that no single issuer exceeds 25% of the Underlying Index weight, and all issuers with a weight above 5% do not cumulatively exceed 50% of the Underlying Index weight. The Underlying Index will include large- and mid-capitalization companies and may change over time. As of August 31, 2019, a significant portion of the Underlying Index is represented by securities of companies in the information technology industry or sector. The components of the Underlying Index are likely to change over time.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 that collectively has an investment profile similar to that of 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 may or may not hold all of the securities in the Underlying Index.The Fund will at all times invest at least 80% of its assets in the securities of its Underlying Index and in depositary receipts representing securities in its Underlying Index. The Fund may invest the remainder of its assets in other securities, including securities not in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index, and in other investments, including futures contracts, options on futures contracts, other types of options and swaps related to its Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.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 Inc. (the “Index Provider” or “MSCI”), 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) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.
