At a board meeting last week, Benmosche told fellow AIG directors that he was 'done' but agreed to think it over after other board members reacted with shock.
Benmosche would receive an annual salary of $3 million in cash and $4 million in AIG common stock as per the previous agreement on August 17.
Attributing to people close to the situation, the Financial Times said the failed sale of AIA has strained relationships at the top levels of the US insurer and tensions are growing between Benmosche and Golub.
In an interview to the 'Wall Street Journal', Benmosche said that AIG, in its current form, is too large. "I feel strongly that AIG is too big today -- it is extremely complex to manage and we need to make sure it's more transparent, that it's smaller, and that we can make it on our own."
In an interview to the Financial Times, AIG Chief Executive Officer Robert Benmosche said it would take at least two years for AIG to sell businesses and earn enough profits to repay the government and persuade it to sell its 80 per cent stake.
