Royal Bank of Scotland is to sell a portfolio of Northern Ireland-based loans to Cerberus Capital Management for £205m.
The sale is being handled by the group's 'bad bank', RBS Capital Resolutions, and is expected to result in a £5m loss once completed.
RBS said the portfolio related to assets worth £1.4bn, and it had generated a loss of around £16m last year.
It said the sale represented the "final material transaction" for RBS Capital Resolutions in Northern Ireland, and was expected to be completed next month.
