Bank of America has agreed to pay a $7.65 million civil penalty to settle charges resulting from the Charlotte bank's multibillion-dollar miscalculation of its capital ratios, a regulator said Monday. The penalty announced by the Securities and Exchange Commission comes after the bank disclosed in April that it had incorrectly accounted for a type of debt it inherited in its 2009 Merrill Lynch acquisition. Bank of America reported the error to the SEC when the bank discovered it in April.
