Fitch: “… did not foresee the magnitude of the decline…or the dramatic shift in borrower behavior…” Moody’s: “We did not . . . anticipate the magnitude and speed of the deterioration in mortgage quality or the suddenness of the transition to restrictive lending.” S&P: “it is now clear that a number of assumptions used in preparing ratings on mortgage-backed securities issued between 2005 and mid-2007 did not work.” Source: US Government Oversight and Reform Committee, Oct 2008 24
