The bank's executive directors, however, have said the terms and conditions of the package had not been "commented on, reviewed or approved" by the bank's ethics committee, its chairman or the bank's board.
 
People familiar with the findings said Wolfowitz will be given a chance to respond before the report is forwarded to the bank's board.
 
But Robert Bennett, his lawyer, said they have asked until next Monday to respond, saying the 48-hour response time was "unreasonable and unfair".
