Fannie Mae and Freddie Mac junior shareholders face an uphill battle in their lawsuits challenging the Treasury’s August 2012 “net worth sweep” that effectively allows Uncle Sam to confiscate all of the companies’ profits, warns a legal expert. Investors are challenging the amended agreements regarding the seniority of Fannie and Freddie preferred stock owned by the federal government over investors’ GSE preferred stocks. More than a dozen lawsuits filed against the government – led by hedge funds Perry Capital and Fairholme Capital Management – are pending in federal district court in Washington, DC, and in the Court of Federal Claims.
