How to audit accruals

This article provides guidance on how to audit accruals with examples. If you are a student preparing for an audit exam or a public practice professional looking to refresh your knowledge, this article will help you develop a thorough understanding of how plan and test accruals.

Accounting frameworks such as US GAAP, IFRS and other generally accepted accounting frameworks require use of accrual basis of accounting. Further, most financial statements report accruals which are often material amounts. Therefore, accruals are one of the frequently audited balances in most audits of the financial statements. For some context, here are the accruals reported by some of the major companies in their recent annual financial statements:

Audit Risks of Accruals and related assertions

There are specific and multiple audit risks associated with accruals. Each of these risks impact one or more financial statement assertions. Understanding these risks will give you necessary knowledge to identify which of these risks are present in your scenario and what audit procedure must be performed to obtain required level of audit evidence.

Assertion impacted: If you guessed Completeness, then you are absolutely right! It is clear from above that accrual recorded may not completely include the balances/transaction which it should, inadvertently or deliberately!

Assertion impacted: Accuracy and Valuation, since complex calculation or estimate may lead to calculation errors or value determined for the amounts being accrued.

Assertion impacted: Cut-off as the title suggests, since accrual have not been recorded in the correct accounting period.

Assertion impacted: Overstatement can impact multiple assertions. In the examples above, it can achieved through incorrect “Cut-off” (booking next year’s accrual in current year) or “Valuation” (recording higher than the expect value) for amounts being accrued.
An important thing to remember here is that not of all these risks are present in every organization and their severity (from low to high) may also depend on nature of organization and maturity of its processes and controls, among various other factors.

Planning procedure to identify relevant risks and assertions

Your next steps in how to audit accrual is to identify which of the risks we discussed above are most likely present in your specific audit or exam scenario. This also include identifying specific financial statement assertions effected by these risks. These can simply be called “Relevant Risk and Assertions”.

Below examples illustrates how to perform and gather information from planning procedure to identify relevant risks and assertions.

Example – Identifying relevant risk and assertions:

  1. Identify risks associated with Orange Inc.’s accruals
  2. Identify the relevant assertions
