 registered investment companies in the securities of other registered investment companies may, among other things, limit investment flexibility and could affect the Fund’s ability to utilize the Central Funds. This could adversely impact the Fund’s investment strategies and operations. The “Investment Objective and Policies - Regulatory Risk” section in the Statement of Additional Information discusses these changes in further detail. Short Sales A short sale is a transaction in which the Fund sells a security or other instrument that it does not own in anticipation that the market price will decline. The Fund may use short sales for investment purposes or for hedging and risk management purposes. The Fund may also take short positions with respect to the performance of securities, indexes, interest rates, currencies and other assets or markets through the use of derivative or forward instruments. When the Fund engages in a short sale of a security, it must borrow the security sold short and deliver it to the counterparty. The Fund may have to pay a fee to borrow particular securities and would often be obligated to pay over any payments received on such borrowed securities. The Fund’s obligation to replace the borrowed security will be secured by collateral deposited with the Fund’s custodian in the name of the lender. The Fund may not receive any payments (including interest) on its collateral. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund may engage in so-called “naked” short sales when it does not own or have the immediate right to acquire the security sold short at no additional cost, in which case the Fund’s losses theoretically could be unlimited. If the price of the security sold short increases between the time of the short sale and the time that the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. The successful use of short selling may be adversely affected by imperfect correlation between movements in the price of the security sold short and securities being hedged if the short sale is being used for hedging purposes. See “Principal Risks of the Fund—Derivatives” and “Principal Risks of the Fund—Short Sales Risk.” See also “Principal Risks of the Fund—Leverage Risk.” The Fund may engage in short selling to the extent permitted by the 1940 Act and other federal securities laws.
