Meaning
Evaluation of past financial activities and records allows an organization to identify errors or fraud that were missed during real-time monitoring. Unlike a concurrent review, a retrospective audit looks at a completed fiscal period and compares the recorded transactions against bank statements and physical inventory. This process provides a thorough view of the company’s financial health and compliance with accounting standards.
The audit stops at the boundary of the selected review period.
Review Timing
Accountants pull a sample of invoices and matching payments to ensure that every expense was authorized and correctly categorized. During a retrospective audit, the team looks for patterns of unusual activity that might indicate systemic failures in the internal controls. This backward-looking approach often uncovers discrepancies that were hidden by the speed of daily operations.
Discovery Potential
Findings from such a review can lead to the restatement of past financial results or the implementation of new oversight policies. If a retrospective audit reveals a material loss that was previously unknown, the company may be required to notify investors or regulators. The cost of the audit is often weighed against the risk of undetected errors causing a larger crisis in the future.
Audit Range
This method cannot prevent a loss that has already occurred.
