Unisys Corporation announced it has entered into an agreement with Massachusetts Mutual Life Insurance Company (MassMutual) to purchase a group annuity contract for approximately $280 million through which it will transfer projected benefit obligations valued slightly less than this amount related to certain retirees under the company's U.S. pension plans to MassMutual. As part of the transfer, the insurance company will assume responsibility for pension benefits for approximately 11,600 retirees and beneficiaries with monthly benefits lower than certain thresholds. There will be no changes to the gross amount, timing, or form of the monthly pension payments.
