Boston Partners Long/Short Equity Fund Investor Class Fonds

The investment seeks long-term capital appreciation while reducing exposure to general equity market risk and a total return greater than that of the S&P 500® Index over a full market cycle. The fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The Advisor intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities. Under normal circumstances, the Adviser expects that the fund's long positions will not exceed approximately 125% of the fund's net assets.
