BAMCO, Inc. (“BAMCO” or the “Adviser”) has agreed that for so long as it serves as the Adviser to the Fund, it will reimburse certain expenses of the Fund, limiting net annual operating expenses (expenses such as portfolio transaction costs, interest, dividend and extraordinary expenses are not subject to the operating expense limitation) to 1.00% of average daily net assets of Retail Shares and 0.75% of average daily net assets of Institutional Shares and R6 Shares.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
