Important Risks: Investing involves risk, including the possible loss of principal. Security prices fluctuate in value depending on general market and economic conditions and the prospects of individual companies. • The securities of large market capitalization companies may underperform other segments of the market. • Mid-cap securities can have greater risks and volatility than large-cap securities. • Growth investing style may go in and out of favor, which may cause the Fund to underperform other equity funds that use different investment styles. • To the extent the Fund focuses on one or more sectors, including the information technology, consumer discretionary and communication services sectors, the Fund may be subject to increased volatility and risk of loss if adverse developments occur. • Because the Fund may hold a limited number of securities, the Fund is subject to a greater risk of loss if any of those securities decline in price. • The Fund may have high portfolio turnover, which could increase its transaction costs and an investor's tax liability. • Foreign investments may be more volatile and less liquid than U.S. investments and are subject to the risk of currency fluctuations and adverse political, economic and regulatory developments.
