€700,000 was taken from the fundraising arm of the Central Remedial Clinic to pay the retirement lump sum of its former CEO.
The Dáil's Public Accounts Committee has heard that the payoff to Paul Kiely was over twice the amount previously disclosed.
Mr Kiely was given a retirement payoff of over €473,000 - far above the €200,000 he told the committee about last month.
In addition, the clinic paid €268,000 to pension company Mercers - so that Mr Kiely's pension would be calculated as if he had continued in the job until November of 2016.
Paul Kiely's successor as chief executive, Brian Conlan (pictured), said he wasn't aware of the arrangements for Mr Kiely's pension.
However he later conceded that, as a director at the time, he would have been asked to sign off on the massive payments.
