Fund Description: iShares Edge MSCI Min Vol USA ETF, formerly iShares MSCI USA Minimum Volatility ETF, formerly iShares MSCI USA Minimum Volatility Index Fund, is an exchange-traded index fund or Index ETF which is a separate investment portfolio of iShares Trust, an open-end investment management company. INVESTMENT OBJECTIVE: The iShares Edge MSCI Min Vol USA ETF seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI USA Minimum Volatility Index. INDEX DESCRIPTION: The MSCI USA Minimum Volatility Index measures the performance of equity securities in the top 85% by market capitalization of equity securities listed on stock exchanges in the United States that have lower absolute volatility. The Index begins with the MSCI USA Index, which is a capitalization-weighted index, and then follows a rules-based methodology to determine weights for securities in the Index that seeks to minimize total risk of the MSCI USA Index. As of September 1, 2011, the Index had 126 constituents. Component companies include consumer staples, health care and information technology companies. FUND STRATEGY: A passive or indexing approach is used to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to beat the Index and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform its 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 keeping portfolio turnover low in comparison to actively managed investment companies. The Fund generally invests at least 90% of its assets in securities of the Index and in depositary receipts representing securities of the Index. The Fund may invest the remainder of its assets in securities not included in the Index, but is believed will help the Fund track the Index, and in futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds. Representative sampling is an indexing strategy that is used which involves investing in a representative sample of securities that collectively has an investment profile similar to the 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 the Index. A Fund may or may not hold all of the securities in the Index. FUND MANAGEMENT: BlackRock Fund Advisors (BFA) serves as the Investment Adviser to the Fund.
