Fannie Mae, Freddie MacBoth Fannie Mae and Freddie Mac, the largest providers of mortgage financing, said today that their portfolios have continued to shrink. Fannie Mae's portfolio shrank at a 5.7 percent annualized rate to 717.4 billion, its lowest level for the year and nearing a record low set in November 2005, when the GSE's portfolio fell to $715.5 billion. Reported delinquencies remained steady at .62 percent of portfolio holdings. Purchases of $13.9 billion weren't enough to offset $6.3 billion in sales and $11.2 billion in portfolio run-off, as the mortgage giant continues to grapple with the effects of an ongoing accounting scandal. GSE regulators earlier in the week announced formal charges filed against former executives of the company, in addition to already a $6.3 billion restatement of income from 2001 to mid-2004. Competitor Freddie Mac didn't fare much better, announcing that its mortgage portfolio fell to $704.3 billion during November. Purchases of $18 billion were nearly offset by a liquidation rate of 26.5 percent, a 150 basis-point increase from October, the company said in a statement. Delinquencies at Freddie Mac held steady in November, representing .52 percent of mortgage holdings.
