Goldman Sachs Group Inc. will pay $26.6 million to settle a lawsuit brought by investors in a $698 million mortgage-backed securities offering, according to papers filed in Manhattan federal court. The Public Employees' Retirement System of Mississippi today asked U.S. District Judge Harold Baer to approve the settlement. The pension fund told Baer earlier this month that both sides had accepted a settlement proposed by a mediator. The amount of the settlement was disclosed in today's filing.
