We recommend that the Office of the Chief Financial Officer maintain and update a listing of all the Office of Personnel Management?s travel charge cardholders on a regular basis, including but not limited to travel cardholders? separation date and travel card cancelation date. In addition, the Business Services and Operations group should reconcile the Office of Personnel Management?s travel charge cardholder listings with Citibank?s records and Office of Personnel Management Human Resources? separation reports. The Business Services and Operations group should follow up with Citibank and the Office of Personnel Management?s Human Resources on any discrepancies.
