New York state's top legal officer issued subpoenas on Wednesday to seven executives who received tens of millions of dollars in 2008 pay from Merrill Lynch & Co before it was taken over by Bank of America Corp , a person familiar with the investigation said.

Last month, Cuomo's lawyers took testimony under oath from former Merrill head John Thain and Bank of America CEO Kenneth Lewis, part of a probe into whether the firm broke securities laws on public disclosure of executive compensation.
