The lawsuit accused Citigroup and its Citigroup Alternative Investments affiliate of misleading investors in a Dec. 14, 2007 letter about the status of the fund’s leveraged, 558 million euro ($756 million at the time) original investment in a syndicated loan arranged for ProSiebenSat1 SE (PSMGn.DE), a large German broadcaster. Investors said Citigroup falsely told them in the letter that the quality of the fund’s portfolio was “fundamentally sound,” but was forced six weeks later to suspend redemptions. Citigroup denied wrongdoing in agreeing to settle.
