BTC iShares MSCI USA Value Factor ETF (VLUE) Exchange: BATS

The Fund seeks to track the investment results of the MSCI USA Enhanced Value Index (the “Underlying Index”), which is based on a traditional market capitalization-weighted parent index, the MSCI USA Index (the “Parent Index”). The Parent Index includes U.S. large- and mid- capitalization stocks, as defined by MSCI Inc. (the “Index Provider” or “MSCI”). The Underlying Index is designed to measure the performance of securities in the Parent Index that exhibit higher value characteristics relative to their peers within the corresponding Global Industry Classification Standard (GICS®) sector. To construct the Underlying Index, the Index Provider calculates a “value score” for each security in the Parent Index using three variables: price-to-book value, price-to-forward earnings and enterprise value-to-cash flow from operations. MSCI uses an algorithm to determine the number of components in the Underlying Index based on the number of constituents in the Parent Index. The number of components is evaluated semi-annually. MSCI assigns weights by multiplying a component's value score by its market capitalization. Weights in the Underlying Index are next normalized so that sectors in the Underlying Index represent the same weight as in the Parent Index. As of July 31, 2019, there were 150 securities in the Underlying Index. As of July 31, 2019, a significant portion of the Underlying Index is represented by securities of companies in the 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 generally will invest at least 90% of its assets in the component 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 and Parent Index are sponsored by 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 Parent Index and publishes information regarding the market value of the Underlying Index and Parent 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.
