Investments in derivatives are counted toward the Funds 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. For purposes of the Funds 80% policy, securities are considered to be those of U.S. issuers where: (i) the company is domiciled in the U.S., (ii) the company is listed on a U.S. stock exchange, (iii) the companys principal operations are conducted in the U.S. or the company does a substantial amount of business in the U.S. or (iv) the issuer of securities is included in the Funds primary U.S. benchmark. Equity securities include common stocks, preferred stocks, warrants and depositary receipts whose price is linked to the value of common stock. The Fund may also purchase convertible securities. The Fund may invest in shares of companies through initial public offerings (IPOs). The Fund may purchase and sell futures contracts, enter into various interest rate transactions such as swaps, caps, floors or collars, currency transactions such as currency forward contracts, currency futures contracts, currency swaps or options on currency or currency futures and swap contracts (including, but not limited to, credit default swaps) and may purchase and sell exchange-listed and over-the-counter (OTC) put and call options on securities and swap contracts, financial indices and futures contracts and use other derivative instruments or management techniques (collectively, Strategic Transactions). The Fund may engage in Strategic Transactions for duration management and other risk management purposes, including to attempt to protect against possible changes in the market value of the Funds portfolio resulting from trends in the securities markets and changes in interest rates or to protect the Funds unrealized gains in the value of its portfolio securities, to facilitate the sale of portfolio securities for investment purposes, to establish a position in the securities markets as a temporary substitute for purchasing particular securities or to enhance income or gain. In selecting investments for the Fund, BFA uses a systematic framework for analyzing companies and seeking proactive risk-management by focusing on theme identification, theme and company evaluation, and portfolio construction. Using this framework, BFA seeks exposure to multiple themes, including emerging and structural trends. Show less
