On May 28, the FHFA, acting on behalf of Fannie Mae and Freddie Mac, dismissed its lawsuit against Citigroup Inc. and certain of its affiliates and employees after reaching a settlement with defendants.  The lawsuit related to over $3.5 billion in RMBS that Fannie Mae and Freddie Mac allegedly purchased from Citigroup.  The suit was one of 18 cases filed by the FHFA against a number of investment banks between July and September 2011.  In this case, as in the others, the FHFA asserted a number of state and federal securities claims alleging that Citigroup made material misrepresentations and omissions in the offering documents for the RMBS at issue.  This is the second of the 18 cases, along with the case against General Electric, in which the FHFA has reached a settlement.  Stipulation.
