Fed Speak, Losses are assets

"Could the Fed go broke? The answer to this question was 'Yes,' but is now 'No,'" said Raymond Stone, managing director at Stone & McCarthy in Princeton, New Jersey. "An accounting methodology change at the central bank will allow the Fed to incur losses, even substantial losses, without eroding its capital." The change essentially allows the Fed to denote losses by the various regional reserve banks that make up the Fed system as a liability to the Treasury rather than a hit to its capital. It would then simply direct future profits from Fed operations toward that liability http://www.reuters.com/article/2011/01/21/us-usa-fed-accounting-idUSTRE70K6OK20110121
