Three months to the day after he became American International Group’s CEO, Robert H. Benmosche may step down from that post amid frustrations about the insurer’s government oversight, according to a report.

The Wall Street Journal reports that at a board meeting last week, Benmosche told a shocked AIG board of directors he was “done,” but would think over his decision to abandon the troubled insurer, after being named its CEO Aug. 10.

The report said Benmosche is having difficulty dealing with constraints imposed by AIG’s government overseers, including a recent compensation review by Kenneth Feinberg, the Obama administration’s “pay czar.” Feinberg oversees the company and the government’s 80% ownership stake amid an $180 billion bailout last year.

Benmosche, other AIG board members and Feinberg met last month regarding compliance with pay policies to retain talent at the insurer, but that meeting did not go well, according to a person familiar with the meeting, cited by the newspaper. That person told the paper that Benmosche feels he is in “an impossible situation” in meeting the government’s demands for the company.

Benmosche did not respond to a request for comment by the Wall Street Journal.

The former chairman, president and CEO of MetLife, Benmosche, 65, replaced Edward M. Liddy as the company’s CEO. Benmosche’s salary of $10.5 million was approved soon thereafter by Feinberg as the largest compensation package approved under the Treasury Department’s oversight on executive pay, according to the Journal.
