What it means
An audit is an independent inspection of a set of financial statements by someone outside the business, and the ASB decides what that inspection has to include. Its pronouncements set out how much evidence an auditor must gather, how to judge the risk that the accounts are wrong, and what the final audit report must say.
The board matters to owners and managers because it shapes both the cost and the intrusiveness of the audit they pay for. When the ASB tightens a requirement, such as how auditors test management's estimates or assess the risk of fraud, fees and the volume of questions sent to the finance team tend to rise.
Its authority stops at private entities. Audits of companies whose shares trade on a public market in the United States are governed instead by the Public Company Accounting Oversight Board (PCAOB), a separate regulator set up by law.
Knowing which rulebook applies tells you how heavy the audit is likely to be. You meet the ASB's work most directly in the wording of your audit report and in the document request list your auditor sends.
A sentence such as "we conducted our audit in accordance with generally accepted auditing standards" is a direct reference to the body of rules the ASB maintains. The ASB has spent years aligning its standards with the international ones issued by the International Auditing and Assurance Standards Board (IAASB), so the two sets now read very similarly.
Differences remain in places, which is why a group with subsidiaries in several countries can still end up with two slightly different audit approaches. The board also issues standards for work that is lighter than a full audit, including reviews and agreed-upon procedures engagements.
That matters when a lender will accept something cheaper than an audit, because the cheaper option still has to follow a defined standard rather than being an informal opinion.
In practice
Real-world examples.
Example
A family-owned engineering firm in Ohio has to produce audited accounts because its bank facility demands them. Its accountant plans the work under the Statements on Auditing Standards the ASB has issued, which is why the audit team writes to the bank directly to confirm the loan balance rather than taking the finance manager's word for it. The owner experiences the standards mainly as an extra fortnight of document requests.
Example
A charity running after-school sports clubs receives a large government grant and must be audited as a condition of the funding. Because ASB standards require the auditor to consider the risk of deliberate misstatement, the team tests how cash donations are recorded and who signs off refunds. The trustees then use the resulting management letter to tighten their cash handling rules.
Example
A software company preparing itself for sale is asked by a prospective buyer whether its last three audits followed recognised standards. The finance director points to the reference to generally accepted auditing standards in each audit report, which tells the buyer the work followed ASB rules rather than a scope invented by a friendly firm. That single line removes a week of due diligence argument.
Case study
Seen in the real world.
Northbridge Cabinetry is an illustrative example, a fictional joinery business with revenue of $18,000,000 and three factories. Its bank asked for audited accounts for the first time after the company drew down a $4,000,000 facility, and the directors assumed an audit would mean a quick review of the year-end balances.
Under the ASB standards their auditor had to assess risk before testing anything, and the riskiest number turned out to be work in progress, where staff estimated how complete each half-built kitchen was. The audit team recounted a sample of jobs, recalculated the estimates and found that work in progress had been overstated by $260,000.
The correction reduced reported profit, which was uncomfortable, but it also handed the directors a genuine finding: their estimating process was optimistic by roughly 4% on every job. In this illustrative case the audit standards did the owners a favour, because the same optimism had been quietly inflating the margins they thought they were winning work at.
Watch out
Common mistakes.
- Assuming the ASB sets the accounting rules as well as the audit rules. Accounting rules for private American companies come from the Financial Accounting Standards Board; the ASB only governs how the audit of those numbers is carried out.
- Treating an audit done under ASB standards as a guarantee that no fraud exists. The standards require the auditor to consider fraud risk and design tests around it, not to examine every transaction.
- Believing the same rulebook covers listed companies. Public company audits in the United States follow PCAOB standards, and the two sets differ on documentation, reporting and inspection.
Questions
People also ask.
Who has to comply with ASB standards?
Any accountant performing an audit, review or similar engagement for a private entity under American professional rules, which in practice means the firm you hire rather than your own finance team.
Does following ASB standards make an audit more expensive?
Usually yes, because the required risk assessment, documentation and testing all take chargeable hours, though a well-prepared finance team with clean records can cut those hours considerably.
Can we ask for an audit under international standards instead?
A group with overseas owners sometimes does, and because the two frameworks are closely aligned the extra work is normally modest rather than a second full audit.
