A number of religious groups have been defending their contribution to the cost of the child abuse redress scheme.

It follows reports that just 13 percent has been received, of the promised 50-50 compensation split with the State.

The Christian Brothers say they're on course to fulfilling their voluntary pledge with €24 million euro paid already and another ten million on the way.

The Sisters of Mercy says it has honoured all of its commitments - and the Oblates of Mary Immaculate, who managed St Conleth's Reformatory in Daingean on behalf of the state until 1971, says it paid it's voluntary contribution in full in 2013.

Initial estimates placed the cost of the redress scheme at €250 million, but the final bill is over €1.5 billion
