Direct OSU to strengthen the administrative and management controls and processes over obtaining and maintaining sufficient supporting documentation. Processes could include: a. implementing controls to ensure that OSU can only reimburse invoices from consultants with active consulting agreements ;b. performing reviews of sabbatical expenses charged to sponsored awards; c. performing reviews of transactions posted in the final month of each award to ensure that PIs do not bill expenses in anticipation of the award’s expiration; and, d. ensuring that all reimbursed travel expenses are supported by original receipts.
