The Fund uses investment techniques that are different from the risks ordinarily associated with equity investments. Such techniques and strategies include merger arbitrage risks, high portfolio turnover risks, options risks, borrowing risks, short sale risks, and foreign investment risks, which may increase volatility and may increase costs and lower performance.
