What Are Roll Forward Procedures in an Audit?

Roll forward procedures are an efficiency tool used in financial audits. They allow an auditor to perform testing on account balances at an interim date, such as September 30th, and then extend the conclusions to the company’s fiscal year-end, like December 31st. This process involves examining transactions that occur only within the intervening “roll forward” period. This approach allows auditors to spread their work throughout the year, avoiding a bottleneck of procedures at the reporting date and creating a more manageable timeline. These practices are governed by professional auditing standards.

Prerequisites for Performing Roll Forward Procedures

An auditor cannot use roll forward procedures without first assessing risk and the reliability of the company’s internal systems. Professional auditing standards, set by the Public Company Accounting Oversight Board (PCAOB) for public companies and the American Institute of Certified Public Accountants (AICPA) for non-public entities, govern this process. A primary condition is the auditor’s evaluation of the company’s control environment. The auditor must have tested the internal controls for the specific account and concluded they were operating effectively before the interim testing date.

This assessment confirms that transactions are being recorded accurately and the system can be relied upon. The auditor must also expect that these controls will continue to function effectively through the end of the fiscal year. Any significant changes to systems, processes, or personnel in the roll forward period could make these procedures inappropriate, as the risk of material misstatement would be too high.

Another prerequisite is the outcome of prior audit work. The auditor must have performed detailed substantive testing on the account balance at the interim date and found no evidence of significant errors or misstatements. If the interim work had uncovered numerous adjustments or a high degree of estimation uncertainty, it would signal that the account is high-risk. In such cases, the auditor would need to perform full substantive testing directly at the year-end.

Executing Roll Forward Procedures

Once the prerequisites are met, the auditor executes procedures focused on transactions between the interim test date and the fiscal year-end. The first step is to obtain a detailed listing of all transactions that affected the account during this roll forward period, which is sourced from the company’s general ledger. This helps the auditor understand the activity since their last detailed review.

The primary audit technique is substantive analytical procedures, which involves analyzing transaction activity for reasonableness and predictability. An auditor might compare the monthly activity in the roll forward period to the prior year or the company’s budget. They would investigate any large or unusual fluctuations to determine their business purpose and ensure they are accounted for correctly.

Auditors often supplement analytical procedures with limited tests of details, which does not involve re-auditing all transactions. Instead, they select a small sample of specific items for closer inspection, focusing on transactions that are individually significant or appear unusual. For instance, a single large, non-recurring transaction would likely be selected for examination of its supporting documentation.

A procedure involves direct inquiry of management. The auditor will hold discussions with knowledgeable personnel, such as the controller or chief financial officer, regarding the roll forward period. Questions focus on whether there were any changes in business operations, accounting policies, or the control environment that could affect the account balance. Management’s responses help corroborate the auditor’s other findings and provide context for the transactions observed.

Application to Key Account Balances

For fixed assets, the process is often straightforward. The auditor obtains a schedule that starts with the tested interim balance, then details all additions and disposals during the roll forward period to arrive at the year-end balance. The work focuses on vouching major additions to purchase invoices and ensuring that disposals were properly recorded.

When applied to accounts receivable, the focus is on the flow of transactions during the roll forward period. Auditors analyze a summary of activity that includes total credit sales, cash collections, and any customer accounts written off. They compare sales and collection trends to prior periods and expectations, and any significant, unexplained spike in sales would be investigated further.

For inventory, roll forward procedures are common when an auditor observes a physical inventory count at an interim date. To extend this work to year-end, the auditor reviews transactions between the count date and the balance sheet date. This involves examining records for significant inventory purchases and analyzing the cost of goods sold recorded during the period.

Documentation and Finalization

Proper documentation is a fundamental aspect of completing roll forward procedures. Professional auditing standards mandate specific documentation requirements, and the auditor’s workpapers must create a clear record that links the interim testing to the final year-end conclusion. This documentation serves as the primary evidence of the work performed and provides a trail for review.

The audit file must include a summary that outlines the specific roll forward procedures performed. This includes detailing the analytical procedures, the results of those tests, and any transactions selected for detailed testing. It will also describe the inquiries made of management along with their responses.

The documentation must culminate in a clear conclusion. The auditor must explicitly state whether the evidence from the roll forward procedures is sufficient to support the year-end account balance. This conclusion affirms that, when combined with effective internal controls and interim testing results, the risk of a material misstatement in the account is acceptably low.
