BTC iShares Global Infrastructure ETF (IGF) Exchange: NASDAQ

The Fund seeks to track the investment results of the S&P Global Infrastructure IndexTM (the “Underlying Index”), which is designed to track performance of the stocks of large infrastructure companies in developed or emerging markets that must be domiciled in developed markets, or whose stocks are listed on developed market exchanges around the world. The Underlying Index includes companies involved in utilities, energy and transportation infrastructure, such as the management or ownership of oil and gas storage and transportation; airport services; highways and rail tracks; marine ports and services; and electric, gas and water utilities. As of March 31, 2020, the Underlying Index was comprised of securities of companies in the following countries: Australia, Brazil, Canada, Chilé, China, France, Germany, Italy, Luxembourg, Mexico, the Netherlands, New Zealand, Singapore, Spain, Switzerland, the United Kingdom (the “U.K.”) and the U.S. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2020, a significant portion of the Underlying Index is represented by securities of companies in the energy, industrials, infrastructure and utilities industries or sectors. 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 generally invests at least 90% of its assets in the component securities of the 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 10% 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 a product of S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), 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.
