Ambac Sues Bank of America Over Countrywide Bonds

``Ambac Assurance Corp. sued Bank of America Corp. over $16.7 billion of mortgage-backed securities, saying the bank’s Countrywide Financial Corp. unit fraudulently induced Ambac to insure bonds backed by improperly made loans. Ambac found that 97 percent of 6,533 loans it reviewed across 12 securitizations sponsored by Countrywide didn’t conform to the lender’s underwriting guidelines... “Bank of America probably didn’t settle because they didn’t want to swallow the amount of money that it’s going to take to satisfy Ambac,” said Alan White, a law professor at Valparaiso University who specializes in housing industry issues. “Nobody wants to be left holding the bag.”''
