including taking short or negative positions), implement a tax or cash management strategy, gain exposure to a particular security or segment of the market, modify the effective duration of the Fund's portfolio investments and/or enhance total return. Hedging and Related Strategies The Fund may (but is not required to) use various investment strategies to seek exposure to foreign currencies, or attempt to hedge exposure to reduce the risk of loss and preserve capital, due to fluctuations in currency exchange rates relative to the U.S. dollar. See “The Fund’s Investment Objective and Strategies—Portfolio Contents and Other Information— Foreign Currencies and Related Transactions.” The Fund may also purchase credit default swaps for the purpose of hedging the Fund’s credit exposure to certain issuers and, thereby, seek to decrease its exposure to credit risk, and it may invest in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio and, thereby, seek to decrease the Fund’s exposure to interest rate risk. See “Portfolio Contents—Credit Default Swaps,” “Portfolio Contents—Structured Notes and Related Instruments” and “Portfolio Contents—Certain Interest Rate Transactions” in this prospectus. Other derivatives strategies and instruments that the Fund may use include without limitation: financial futures contracts; short sales; other types of swap agreements or options thereon; options on financial futures; and options based on either an index or individual debt securities whose prices, PIMCO believes, correlate with the prices of the Fund’s investments. Income earned by the Fund from its hedging and related transactions may be subject to one or more special U.S. federal income tax rules that can affect the amount, timing and/or character of distributions to Common Shareholders. For instance, income earned by the Fund from its foreign currency hedging activities, if any, may give rise to ordinary income that, to the extent not offset by losses from such activities, may be distributed to Common Shareholders and taxable at ordinary income rates. Therefore, any foreign currency hedging activities by the Fund can increase the amount of distributions taxable to Common Shareholders as ordinary income. See “Tax Matters.” There is no assurance that these hedging strategies will be available at any time or that PIMCO will determine to use them for the Fund or, if used, that the strategies will be successful. PIMCO may determine not to engage in hedging strategies or to do so only in unusual circumstances or market conditions. In addition, the Fund may be subject to certain restrictions on
