MFS Investment Management (“MFS”) announced that, at a meeting held today, the Board of Trustees of MFS InterMarket Income Trust I (the “fund”) (NYSE: CMK), a closed-end management investment company, approved a plan of liquidation and termination for the fund. The plan is currently expected to take effect on or about September 9, 2015.

In determining to liquidate the fund, the fund's investment manager, MFS Investment Management, and the Board considered a variety of factors. These included the submission to the fund of proposals for the 2015 annual meeting of shareholders of the fund made by certain shareholders holding large blocks of the fund's shares and the potential costs and other consequences to the Fund and its shareholders of contesting those proposals or of implementing them if approved by shareholders; the relatively small size of the fund; and the fund's trading discount. MFS and the Board also considered alternatives, including merging the fund into another investment company or open-ending the fund or conducting a tender offer, and on balance determined that a liquidation would be in the best interests of the fund and its shareholders.

Subsequent to the effective date of the plan, the fund will begin the orderly liquidation of its assets, determine and pay, or set aside in cash or cash equivalents, an amount at least equal to all known or reasonably ascertainable liabilities and obligations of the fund, including liabilities associated with the fund’s financial leverage, and make one or more liquidating distributions to the fund’s common shareholders. The fund may also begin to liquidate certain holdings prior to the effective date of the plan. The fund has fixed the close of business on September 9, 2015 as the record date for determining the common shareholders of the fund entitled to receive liquidating distributions. As of that time, the share transfer books of the fund will be closed, and the trading of the fund’s shares on the New York Stock Exchange is expected to be suspended. The MFS Closed-End Funds Dividend Reinvestment and Cash Purchase Plan for the fund will be terminated and shares held in the plan will be liquidated and proceeds will be remitted directly to shareholders participating in the plan. The recurring monthly distribution scheduled for September will be suspended and the August monthly distribution will be the final monthly distribution. The fund’s liquidating distributions will be paid in cash. It is currently anticipated that the liquidation will be completed on or about September 25, 2015.
