The Board of Trustees of the fund has approved the proposed reorganization of the fund into MFS Municipal Income Fund. The proposed transaction is subject to approval by the shareholders of the fund at a shareholders’ meeting expected to be held in October 2011. No assurance can be given that the reorganization will occur.

Under the terms of the proposed Plan of Reorganization, the fund’s assets and liabilities would be transferred to MFS Municipal Income Fund in return for shares of MFS Municipal Income Fund with equal total net asset value as of the valuation date. These MFS Municipal Income Fund shares would be distributed pro rata to shareholders of the fund in exchange for their fund shares. Current fund shareholders would thus become shareholders of MFS Municipal Income Fund and receive shares of MFS Municipal Income Fund with a total net asset value equal to that of their shares of the fund at the time of the reorganization. The proposed transaction is expected to be a tax-free event for federal income tax purposes.

The investment objective of the fund is to seek total return with an emphasis on income exempt from federal income tax and personal income tax, if any, of Florida, but also considering capital appreciation.
