The Funds investments in derivatives will be 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. The Fund may invest in fixed, variable and floating rate instruments, including participations and assignments, of any duration or maturity. The Fund may invest without limit in credit-related instruments rated below investment grade or deemed equivalent by Fund management, which are commonly referred to as junk bonds. The Fund may invest in foreign securities (including emerging markets) without limit. The Fund may invest in non-U.S. dollar denominated investments, including investments denominated in European and Asian currencies and in other non-U.S. and emerging market currencies. The Funds investments in non-U.S. dollar based assets may be made on a currency hedged or unhedged basis. The Fund may invest up to 20% of its total assets in equity instruments, including common stock, depositary receipts, rights, warrants and other instruments whose price is linked to the value of common stock. The Fund may hold long or short positions in equity instruments, and may invest in equity instruments of issuers of any market capitalization. The Fund may also gain both long and short exposure to credit-related instruments by entering into a series of purchase and sale contracts or by investing in, among other instruments, swaps, including total return, credit default, index and interest rate swaps; options; forward contracts; futures contracts and options on futures contracts that provide long or short exposure to other credit obligations; credit-linked notes that provide long or short exposure to other credit obligations; repurchase agreements; reverse repurchase agreements; dollar rolls; exchange-traded funds and closed-end registered investment companies, which may be managed by BlackRock or one of its affiliates; and other similar transactions. The Fund may engage in short sales for hedging purposes or to enhance total return. The Fund also may make short sales against the box without limitation. In this type of short sale, at the time of the sale, the Fund owns or has the immediate and unconditional right to acquire the identical security at no additional cost. As part of its normal operations, the Fund may hold high quality money market securities and invest in money market funds, including affiliated money market funds, pending investments or when it expects to need cash to pay redeeming shareholders. The Fund also may invest in these securities in order to achieve its investment goal. Money market securities are short term securities consisting primarily of short term U.S. Government securities, U.S. Government agency securities, securities issued by U.S. Government sponsored enterprises and U.S. Government instrumentalities, bank obligations, commercial paper, including asset backed commercial paper, corporate notes and repurchase agreements. Fund management employs a credit relative value framework that looks at the credit spectrum as a whole (e.g., by using credit spread relationships as a proxy for determining relative value) as well as within and across capital structures, or at opportunity sets across the credit spectrum in the case of narrower spreads. The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies. The Fund may borrow from banks for investment purposes. Show less
