For certain assets acquired, the proceeds from the disposal of the underlying collateral in a debtor connection exceeded the carrying value of those loans and receivables. This surplus is recognised in the income statement as realised profits on loans. Of the total amount of €531m recognised, €306m (2012: €108m) was generated from debtors who have fully repaid all NAMA debt and any further cash received is recognised as profit. A further €225m (2012: €64m) of surplus income is recognised on specific loan assets within a debtor connection where the cash generated and received by NAMA has exceeded the loan carrying value; and the estimated discounted cash flows for the total debtor connection are greater than the total loan carrying values. Further information on the recognition of surplus income is included in Note 3, critical accounting estimates and judgements.

During the year, the Group disposed of certain loans and receivables to third parties. Profit or loss on disposal is measured as the difference between proceeds of sale received and the carrying value of those loans and receivables.
