More good news.

Unlike bank accounts, money market funds aren't insured by the federal government. They almost never fail. Unbeknownst to most investors, some of the largest money market funds today are putting part of their cash into one of the riskiest debt investments in the world: collateralized debt obligations backed by subprime mortgage loans. CDOs are packages of bonds and loans, and almost half of all CDOs sold in the U.S. in 2006 contained subprime debt, according to a March report by Moody's Investors Service.
