BBC Trust chairman Lord Patten and BBC acting director general Tim Davie are facing questions from MPs over the corporation's response to the Jimmy Savile case.
Lord Patten said the two BBC inquiries - one into the culture and practices at the BBC and another into the shelved Newsnight programme - will clearly be expensive.
Facing the culture, media and sport committee, Lord Patten added that the Pollard report into Newsnight will be published next month and will appear in full unless there are legal redactions.
Davie said the legal costs on the Pollard investigation had so far ran to around £200,000.
