Concentration in a particular industry or sector will subject the Funds to loss due to adverse occurrences that may affect that industry or sector. The Funds may use derivatives which may involve risks different from, or greater than, those associated with more traditional investments. A Fund's emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Also, a company may reduce or eliminate its dividend after the Fund's purchase of such a company's securities. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including political, diplomatic, economic, foreign market and trading risks. In addition, a Fund's investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund's returns. See the prospectus for specific risks regarding the Funds.

The securities of small capitalization companies are often more volatile and less liquid than the stocks of larger companies and may be more affected than other types of securities during market downturns. Compared to larger companies, small capitalization companies may have a shorter history of operations, and may have limited product lines, markets or financial resources.

Companies involved with the Internet, technology and e-commerce are exposed to risks associated with rapid advances in technology, obsolescence of current products and services, the finite life of patents and the constant threat of global competition and substitutes.

Past performance does not guarantee future results. Shares are bought and sold at market price (not NAV), are not individually redeemable, and owners of Shares may acquire those Shares from the Funds and tender those shares for redemption to the Funds in Creation Unit aggregations only, consisting of 50,000 Shares. Brokerage commissions will reduce returns. The market price of Shares can be at, below, or above NAV. Market Price returns are based upon the midpoint of the bid/ask spread at 4:00 PM Eastern time (when NAV is normally determined), and do not represent the returns you would receive if you traded Shares at other times.
