This fund may not be suitable for all investors. • Investing in sector funds is more volatile than investing in broadly diversified funds, as there is a greater risk due to the concentration of the funds’ holdings in issuers of the same or similar offerings. • The fund may invest in American Depositary Receipts (“ADRs”) therefore subjecting the value of the fund’s portfolio to fluctuations in foreign exchange rates. • The fund is subject to active trading risks that may increase volatility and impact the fund’s ability to achieve its investment objective. • This fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of fund shares than would occur in a more diversified fund.
