Investments carry risks, including possible loss of principal. Additional risks may be associated with investments outside the United States, especially in emerging markets, including currency fluctuations, illiquidity, volatility, and political and economic risks. Investments in small- and mid-capitalization companies may increase the risk of greater price fluctuations. A short position will lose value as the security's price increases. Theoretically, the loss on a short sale can be unlimited. Investments in derivatives are subject to the risks associated with the securities or other assets underlying the pool of securities, including illiquidity and difficulty in valuation. Non-diversified funds can be more volatile than diversified funds. Investments in the Fund are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

Diversification does not assure or guarantee better performance and cannot eliminate the risk of investment losses.

Funds invested in a limited number of holdings may expose an investor to greater volatility.

Class I shares may not be available to all investors. Minimum investments for the I share class may be higher than those for other classes.

There is no guarantee that the Fund will meet its investment objectives.
