Freddie Mac's report, for example, shows that the percentage of mortgages in its portfolio with subprime characteristics rose rapidly after 2004. Tables 1 and 2 show that for each category of mortgages with subprime characteristics, most of the portfolio of loans with those characteristics was acquired from 2005 to 2007. For example, 83.8 percent of Fannie's and 90 percent of Freddie's interest-only loans as of June 2008 were acquired from 2005 to 2007, and 57.5 percent of Fannie's and 61 percent of Freddie's loans with FICO scores of less than 620 as of June 2008 were acquired from 2005 to 2007. It seems unlikely that competing for market share or complying with HUD regulations–which contained no enforcement mechanism other than disclosure and delay in approving requests for mission expansions–could be the reason for such an obviously destructive course.
