Review Engagement

A review engagement is an assurance service in which an accountant applies analytical procedures and makes inquiries of management to gather evidence about whether financial statements are materially misstated. It provides less assurance than a full audit engagement but more than a compilation engagement—a middle ground between no testing and comprehensive audit work.

The middle ground between compilation and audit

Three main tiers of accountant service exist for private companies and non-profits. A compilation engagement means the accountant presents financial information in standard format but gathers no evidence and offers no assurance. The accountant is a typist, not a tester. A full audit means the accountant examines transactions, tests internal controls, and issues an opinion on whether statements are fairly presented. A review sits between: the accountant does not conduct the systematic testing of a full audit, but does perform meaningful procedures designed to surface material errors.

Private companies often choose a review because they do not need an audit (perhaps no lender or major creditor demands one) but want something more credible than a compilation. A bank might require a review before extending a line of credit. A non-profit’s board might want assurance that year-end statements are reasonable before presenting them to donors.

How review procedures work

In a review, the accountant relies heavily on analytical procedures—comparing the current year’s numbers to prior years, to industry benchmarks, to budgets that management has prepared, and to statistical expectations. If revenue dropped 15% without explanation, or if a specific expense account spiked unexpectedly, those patterns trigger inquiry.

The accountant also makes inquiries of management. Has anything changed in the business or operations? Have there been unusual transactions? Are there any known errors or irregularities? Are all year-end accruals and cutoffs complete? The accountant is not performing the forensic investigation of a full audit, but is asking informed questions based on knowledge of the business and the analytical findings.

Unlike a full audit, a review does not involve detailed transaction testing, evaluation of internal controls, confirmation of balances with third parties, or physical inspection of assets. The accountant does not perform the deep procedures that an auditor would. Instead, the review is a layer of informed scrutiny—enough to identify obvious problems, but not enough to detect a well-concealed fraud or subtle accounting error.

The limited assurance conclusion

Because the procedures are more limited, the accountant’s conclusion is also more modest. An auditor issues an opinion, stating that the statements are fairly presented or describing specific problems. A reviewer issues a “limited assurance conclusion,” which typically reads: “Based on our review, we are not aware of any material modifications that should be made to these financial statements in order for them to be in accordance with generally accepted accounting principles.”

This language is intentionally careful. The reviewer is not saying the statements are correct, only that nothing obvious suggested otherwise. An auditor, by contrast, is stating affirmatively that the statements present fairly. The reviewer’s conclusion offers less certainty but still provides some comfort to the user—considerably more than a compilation would.

If the reviewer encounters evidence of material misstatement or if management refuses to make a necessary disclosure, the reviewer can issue a qualified conclusion or, in the most severe case, a report stating that the accountant is unable to complete the review. These outcomes are rare; if they occur, they signal a serious problem.

Common reasons to choose a review

A company might choose a review over an audit for cost and efficiency. Audits require extensive testing and documentation; reviews do not. For a small or mid-sized private company, a review might cost one-third to one-half the price of an audit, and it can often be completed more quickly.

Lenders and investors sometimes accept reviews instead of audits from established private companies with stable ownership and operations. A review offers enough comfort that the financial statements are reasonable without the full expense of an audit.

Non-profits often use reviews. Donors and boards want assurance that funds are being accounted for properly, but a non-profit may not have the resources for a full audit. A review provides meaningful assurance at reasonable cost.

The role of management cooperation

A review is heavily dependent on management’s honesty and cooperation. Because the accountant is not testing transactions deeply, the accountant relies on management’s representations that there are no errors, omissions, or irregular transactions. If management is evasive or refuses to answer inquiries, the accountant cannot complete the review and must report this limitation.

For this reason, a review is most effective when the client has honest, capable financial leadership. A client attempting to conceal fraud can defeat a review more easily than a full audit—the reviewer is not digging as deeply. Conversely, a competent, transparent management can provide the information the reviewer needs to form a reasonable limited assurance conclusion.

Review versus audit engagement versus agreed-upon procedures

The three services exist on a spectrum. An audit is comprehensive; the auditor tests the full system of internal controls and applies procedures to gain reasonable assurance about every material area. A review applies analytical and inquiry procedures to a smaller scale; the accountant gains limited assurance but does not test controls systematically. Agreed-upon procedures are the narrowest—the client specifies what to test, the accountant tests only that, and issues no assurance conclusion at all.

A client might use multiple services. A company might have a review of its year-end statements but commission agreed-upon procedures to test compliance with a specific loan covenant. Or a larger firm might have an audit of the consolidated entity but reviews of smaller subsidiaries.

Standards and regulation

Reviews for non-public entities are governed by the Statements on Standards for Accounting and Review Services (SSARS), issued by the American Institute of Certified Public Accountants. These standards define what procedures are required, how the accountant should handle inquiries, how to report findings, and what to do if the accountant encounters evidence of misstatement or fraud.

For public companies, the rules are different—the Securities and Exchange Commission does not permit reviews instead of audits. Public company financial statements require full audits by independent auditors.
