Standard & Poor's Ratings Services could face a much higher legal bill than the $5 billion sought by the federal government as more and more states join the battle against the credit-ratings firm, the Wall Street Journal reported today. A raft of lawsuits this week from attorneys general from several states, including California and Iowa, is compounding S&P's legal woes over its role during the financial crisis of 2008-2009. The Justice Department on Tuesday sued S&P for allegedly causing some banks and credit unions to lose $5 billion after relying on the company's ratings of mortgage-linked securities. Thirteen states and the District of Columbia have followed in the Justice Department's footsteps, filing separate lawsuits against S&P on Tuesday. The California attorney general alone is suing S&P for about $4 billion to recover funds for two of the country's largest public pension funds, according to its lawsuit.
