Detective control Control description Examples
Regular supervisory review of account activity, reports, and reconciliations Management compares information about current performance to budgets, forecasts, prior periods, or other benchmarks to measure the extent to which goals and objectives are being achieved and to identify unexpected results or unusual conditions that require follow-up.
  • Compare budget to actual expenses and investigate significant differences.
  • Routinely spot-check transactions, records, and reconciliations to ensure expectations are met as to timeliness, completeness, and segregation of duties.
  • Follow up on unexpected results or unusual transactions. Ask for explanations of unexpected results and ask for reasons for unusual transactions.
  • Document your reviews of reports and reconciliations by initiating and dating the reports.
Physical Inventories Departments with significant inventories should maintain inventory controls over the items. Inventory items received and issued should be recorded, so that a current “book” balance is always known Periodically, a person who is independent of the inventory purchasing and inventory custody functions should physically count the inventory items. The counts should be compared to the “book” balances. Missing items should be investigated, resolved, and analyzed for possible control deficiencies.
Control self-assessment Departments should examine and improve existing internal controls and/or implement new internal controls to mitigate risks associated with a process or function. Departments are encouraged to utilize the internal controls checklists that can be located in the forms section of the Division of Finance website. The objective of the internal controls checklists is to provide campus community with a tool for evaluating their internal control structure and general compliance by business process.
