Fund Description: FlexShares STOXX Global Broad Infrastructure Index Fund is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the FlexShares Trust, an open-end investment management company. INVESTMENT OBJECTIVE: The FlexShares STOXX Global Broad Infrastructure Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the STOXX Global Broad Infrastructure Index. INDEX DESCRIPTION: The STOXX Global Broad Infrastructure Index reflects the performance of a selection of equity securities of infrastructure-related companies that are domiciled or traded in developed and emerging markets around the world (including the U.S.). The companies included in the Index derive at least 50% of their revenues from the ownership, development, construction, financing or operation of infrastructure assets, as determined by STOXX (the Index Provider) pursuant to its index methodology. Infrastructure assets are defined by the Index Provider as the physical structures and networks upon which the operation, growth and development of a community depends, and include: (a) communication (cable and satellite, data centers, wireless, wireless towers and wireline); (b) energy (energy utilities and midstream energy); (c) government outsourcing/social (correctional facilities, hospitals and postal services); (d) transportation (air transportation, passenger transportation, rail transportation, road transportation and water transportation; and (e) utilities (waste management and water utilities). Constituents of the Index may include common and preferred stocks, publicly-traded units of master limited partnerships (MLPs), and real estate investment trusts (REITs). 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 it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Representative sampling is a strategy used to manage the Fund by investing in a representative sample of securities that collectively has an investment profile close to the Index. 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. The Fund may or may not hold all of the securities that are included in the Index. Funds that employ a representative sampling strategy may incur tracking error risk to a greater extent than a fund that seeks to replicate an index. The Fund generally will invest under normal circumstances at least 80% of its total assets in the securities of the Index and in American Depositary Receipts and Global Depositary Receipts based on the securities in its Index. The Fund may also invest up to 20% of its assets in cash and cash equivalents, including shares of money market funds, futures contracts, options on futures contracts, foreign currency contracts, options and total return swaps, as well as securities not included in the Index. FUND MANAGEMENT: Northern Trust Investments, Inc. (NTI), an indirect subsidiary of Northern Trust Corporation, serves as the Investment Adviser of the Fund.
