A former advisor to NAMA has contradicted the agency, by claiming he did have access to sensitive information about its loans.
Brian Rowntree says members of the Northern Ireland Advisory Committee did possess information that was commercially useful.
Another former member of the committee, Frank Cushnahan, was connected to a fixers' fee for the sale of some loans, but NAMA said he did not have access to useful information.
Mr Rowntree has told the Public Accounts Committee that's not the case.
"If I was - hypothetically - if I was conducting due diligence on behalf of an intended purchaser, I'd be smiling if I had a document like that because it would give me a clear indication as to the potential of the land bank, not just for my loans but other loans."
