MFS Municipal Income Trust (NYSE: MFM), MFS Investment Grade Municipal Trust (NYSE: CXH), MFS California Municipal Fund (NYSE MKT: CCA), MFS High Income Municipal Trust (NYSE: CXE), and MFS High Yield Municipal Trust (NYSE: CMU) today announced that the Board of Trustees of each fund has approved a refinancing plan that is expected to result in the outstanding leverage remaining unchanged for each fund. As part of the refinancing plan, each fund plans to redeem all of its currently outstanding Variable Rate Municipal Term Preferred Shares, Series 2016/9 (the “Series 2016/9 VMTPS”) which have a September 2016 maturity date. In addition, each of MFM, CXH, CXE and CMU plan to redeem all of its currently outstanding auction rate municipal preferred shares (“ARPS”). The redemption of each fund’s respective Series 2016/9 VMTPS and ARPS will be subject to the receipt of financing in the form of new preferred leverage. The Series 2016/9 VMTPS and ARPS will be redeemed at their respective liquidation preferences per share plus additional amounts representing any dividend amounts owed. Taking into account the relatively small amount of ARPS of each fund that remain outstanding following tender offers conducted in 2012, the availability of replacement leverage and other factors, the respective Board of each fund approved the redemption of the remaining ARPS at full liquidation preference as being in the best interests of the fund and its shareholders.

Details regarding the specific terms and timing of the above-described redemptions will be communicated as appropriate at a later date through filings with the Securities and Exchange Commission and public press releases.
