MMI Investments, L.P., which owns approximately 9.1 percent of the company's shares, is one of the company's largest shareholders. "The Board is committed to enhancing value for our shareholders, and is pleased to welcome Clay and Charles as directors," said Ric Duques, Unisys Chairman. "The Board and management will benefit from their experience and guidance as we continue to drive to enhance shareholder value." Clay Lifflander said "We are firm believers that there is significant, unrealized value in Unisys. We are excited to work with the other members of the Board and look forward to combining our efforts to improve Unisys performance." As previously announced, the company is working with its investment bankers to help the Board explore certain portfolio rationalization and other actions to enhance shareholder value. Unisys has recently retained Goldman Sachs to assist in this exploration. There can be no assurance that any such transaction will be pursued or consummated.
