Among the payoffs revealed by a National Audit Office is that of the BBC's former deputy director general Mark Byford who reportedly received £949,000 when he left the corporation in 2011.
BBC HR director Lucy Adams admitted to the committee that the size of the payoff was "uncomfortable," but said it had been agreed at the time because Mr Byford agreed to leave before the stipulated 12 month notice period.
It was "customer practice at that time," she added.
Former BBC director-general Mark Thompson has hit back in the row over bumper pay-offs to senior staff.
Four BBC bosses admitted that the corporation had 'lost the plot' after a damning report revealed the scale of payoffs to former staff.
