Figures in AIB's annual report show the bailed-out bank paid its top management €3.6m last year, down from just over €5m the previous year.
The figure is the combined bill for executive and non-executive directors.
The bank’s finances were badly hit in 2009 following the implosion of the property market.
AIB's former Chief Executive Eugene Sheehy earned €892,000 in 2009, down from €1.15m in 2008, according to the report. He retired from the position on 30 November.
Colm Doherty, who was appointed as the bank's Managing Director towards the end of last year, saw his salary grow from €822,000 to €833,000 between 2008 and 2009.
Mr Doherty took over in early November, so December and part of November reflect his salary at the capped rate of €500,000.
AIB's former Chairman Dermot Gleeson, who retired at the end of June, took home €203,000 for his services, a decrease from €475,000 the previous year.
Sean O'Driscoll, a non-executive director of the bank who is due to retire this year, waived his fee for 2009.
Mr O'Driscoll, who is the Chief Executive of Glen Dimplex, is continuing to do the work free this year.
Loans and credit cards
For the first time, the annual report also contains details on the amount of money the bank's directors have out on loans, credit cards and overdrafts.
It shows that Mr Gleeson reduced his loan from the bank from €2.3m to €1.77m.
His overdraft or credit card outstanding at the end of 2009 was €12,000 compared to €42,000 at the end of 2008.
By the end of last year, Mr Doherty had an overdraft of €1,000, down from €3,000 at the end of 2008.
