BTC iShares Intermediate Government/Credit Bond ETF (GVI) Exchange: BATS

The Fund seeks to track the investment results of the Bloomberg Barclays U.S. Intermediate Government/Credit Bond Index (the “Underlying Index”), which measures the performance of U.S. dollar-denominated U.S. Treasury bonds, government-related bonds (i.e., U.S. and non-U.S. agencies, sovereign, supranational and local authority debt) and investment-grade (as determined by Bloomberg Index Services Limited (the “Index Provider” or “Bloomberg”)) U.S. corporate bonds that have a remaining maturity of greater than one year and less than ten years. As of February 29, 2020, there were 4,952 issues in the Underlying Index. As of February 29, 2020, a significant portion of the Underlying Index is represented by treasury securities. The components of the Underlying Index are likely to change over time.The Underlying Index consists of U.S. government, government-related and investment-grade U.S. credit securities that have a greater than one year and less than ten years remaining to maturity and have $300 million or more of outstanding face value. In addition, the securities in the Underlying Index must be denominated in U.S. dollars and must be fixed-rate and non-convertible. Excluded from the Underlying Index are certain special issues such as targeted investor notes, state and local government series bonds and coupon issues that have been stripped from bonds. Also excluded from the Underlying Index are structured notes with embedded swaps or other special features, private placements, floating-rate securities and bonds that have been issued in one country's currency but are traded outside of that country in a different monetary and regulatory system (Eurobonds). The Underlying Index is market capitalization-weighted and the securities in the Underlying Index are updated on the last business day of each month.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 value and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder 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. 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 Bloomberg, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
