v) as part of its overall portfolio management strategies involving the use of derivative instruments. A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline or will underperform relative to other securities held in the Fund’s portfolio. When the Fund makes a short sale, it will often borrow the security sold short and deliver it to the broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon conclusion of the sale. In connection with short sales of securities, the Fund may pay a fee to borrow securities or maintain an arrangement with a broker to borrow securities and is often obligated to pay over any accrued interest and dividends on such borrowed securities. 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 capital 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 the securities being hedged. The Fund may invest pursuant to a risk arbitrage strategy to take advantage of a perceived relationship between the value of two securities. Frequently, a risk arbitrage strategy involves the short sale of a security. The Fund may engage in short sales “against the box.” A short sale is “against the box” to the extent that the Fund contemporaneously owns, or has the right to obtain at no added cost, securities identical to those sold short. The Fund will engage in short selling to the extent permitted by the federal securities laws and rules and interpretations thereunder. To the extent the Fund engages in short selling in foreign (non-U.S.) jurisdictions, the Fund will do so to the extent permitted by the laws and regulations of such jurisdiction.

The Fund may also engage in so-called “naked” short sales (i.e., short sales that are not “against the box”), in which case the Fund’s losses could theoretically be unlimited, in cases where the Fund is unable for whatever reason to close out its short position. The Fund has the flexibility to engage in short selling to the extent permitted by the 1940 Act and rules and interpretations thereunder. Such transactions also can be subject to the risks discussed under “Derivative Instruments,” in addition to the risks discussed in this section. Illiquid Investments As
