The NAMA FOI unit stated: "Receivers appointed to NAMA-secured properties are selected from NAMA's insolvency service provider panel which was established following a competitive public procurement process.
The unit stated: "Arising from this process, competitive fixed-fee rates were achieved relative to prevailing market norms. In general, fees are not paid to receivers directly by NAMA but are instead paid out of the proceeds of assets under receivership or the management of these assets, pending realisation.
The unit states that "fees for any particular insolvency are set by reference to the fees quoted by the insolvency practitioner as part of the public procurement process".
The unit went on to add: "All appointments are subject to on-going monitoring and evaluation and, in many cases, additional fee reductions are negotiated to ensure that fees are appropriate for the amount of work remaining on any given appointment."
"Typically fees reduce as the assignment progresses and the number of assets reduces by way of disposals or otherwise. However, this depends on the complexity of the insolvency and the issues that may emerge during its course."
Over the course of NAMA's operation, Grant Thornton has been paid just over €20 million between its Irish and UK units for its receiver work.
One of the 'Big Four' accountancy firms, KPMG has received €14.8 million in fees, while Duff & Phelps as received €12 million, RSM Ireland- €12.6 million, Deloitte - €11.2 million, Mazars - €9.8 million and Pwc - €9.1 million.
