ISHARES EDGE MSCI MULTIFACTOR UTILITIES ETF (UTLF) Exchange: BATS

DELISTED - The Fund seeks to track the investment results of the MSCI USA Utilities Diversified Multiple-Factor Capped Index (the “Underlying Index”), which has been developed by MSCI Inc. (the “Index Provider” or “MSCI”). The Underlying Index is designed to select equity securities from the MSCI USA Utilities Index (the “Parent Index”) that have high exposure to four investment style factors: value, quality, momentum and low size, while maintaining a level of risk similar to that of the Parent Index. The Underlying Index is also constrained in its construction to limit turnover and has a capping methodology applied to issuer weights so that no single issuer of a component exceeds 25% of the Underlying Index.MSCI, in selecting equity securities from the Parent Index, assigns a composite score for a security through a proprietary model based on four equally-weighted investment style factors: the value score is derived from a company’s valuation ratios (e.g., forward share price to earnings, share price to book value and enterprise value to operating cash flow); the quality score is calculated from a company’s underlying metrics (e.g., return-on-equity, debt-to-equity and earnings variability); the momentum score is calculated through a global equity model, which aims to measure a security’s sustained relative performance against the global market over a two-year period and against other securities based in the same country over the previous six and 12 months (with a one month lag); and the low size score is derived from a global equity model that seeks to measure the market capitalization of a company as compared to other companies based in the same country.As of August 31, 2017, the Underlying Index consisted of approximately 26 U.S. companies. The Underlying Index may include large- and mid-capitalization companies. As of August 31, 2017, a significant portion of the Underlying Index is represented by securities of utilities companies. 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 keeping 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 is 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 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.
