Bank of America Corp settled a shareholder lawsuit that it misled investors about the acquisition of Merrill Lynch by agreeing to a payment of $2.43 billion. The five plaintiffs included the State Teachers Retirement System of Ohio and the Teacher Retirement System of Texas. The plaintiffs accused Bank of America under Ken Lewis of making false and misleading statements about losses relating to the acquisition and planned to seek $20 billion if the case went to trial on Oct. 22. The series of never ending lawsuits and settlements are hobbling the bank's effort to recover. Company figures show Bank of America setting aside $42 billion for litigation costs, payments and reserves.
