A stipulation of the European Commission's decision of 26 February 2010 on the "Establishment of a National Asset Management Agency (NAMA): Asset relief scheme for banks in Ireland", (Ref: State aid N725/2009 - Ireland), was a requirement that the Irish authorities "report on a yearly basis on the use of such post acquisition powers to both the Commission and the Irish competition authorities (paragraph (74)vii.7)". The Commission's decision is publically available via the following link: http://ec.europa.eu/competition/state_aid/cases/234489/234489_1086237_117_2.pdf.
I can confirm that yearly reports on NAMA's use of post-acquisition powers have been submitted to the European Commission and Irish competition authorities for the years 2010 - 2016 inclusive, a total of seven such reports.
