Eaton Vance Tax-Managed Buy-Write Income Fund’s primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation. The Fund invests in a diversified portfolio of common stocks and writes call options on one or more U.S. indices on a substantial portion of the value of its common stock portfolio to seek to generate current earnings from the option premium. The Fund's portfolio managers use the adviser's and sub-adviser's internal research and proprietary modeling techniques in making investment decisions. The Fund evaluates returns on an after tax basis and seeks to minimize and defer federal income taxes incurred by shareholders in connection with their investment in the Fund.
