Former American International Group Inc CEO Maurice ‘Hank’ Greenberg will return to the witness stand on Wednesday to continue to defend the actions of a retirement bonus fund that AIG is trying to reclaim in federal court. In testimony Tuesday, Greenberg said the fund was “not just for AIG employees.” Under examination by AIG lawyer Theodore Wells, Greenberg said the fund had many other purposes. One was to allow Starr to control AIG, Greenberg said. “They had confidence in me,” Greenberg said.
