Pronouncement Types in AUD: ASUs, SASs, SSAEs, and Related Guidance

AUD candidates do not need to memorize every pronouncement number, but they do need to know what kind of authority a label represents. An ASU changes accounting guidance. A SAS changes nonissuer audit requirements. An SSAE changes attestation requirements. A SSARS changes preparation, compilation, or review requirements. PCAOB standards apply in public-company and other PCAOB-covered contexts.

The exam often gives a pronouncement label as a clue. The correct response depends on whether the update affects management’s financial reporting, the auditor’s procedures, the level of assurance, or the report.

	    F --> K["SSARS / AR-C"]
	    G --> L["PCAOB AS, AT, ethics, independence, or quality standards"]

This workflow prevents a common AUD error: applying audit-standard logic to an accounting update, or treating an attestation engagement as if it were a financial statement audit.

Main Pronouncement Types

Accounting Standards Updates

Accounting Standards Updates are FASB pronouncements that amend the Accounting Standards Codification. They are accounting guidance, not audit guidance. The auditor cares about an ASU because management must apply the updated reporting framework, and the auditor must obtain evidence about that application.

For example, a revenue or lease ASU may affect:

• which transactions are recognized
• when revenue or expense is recorded
• how assets and liabilities are measured
• which disclosures are required
• which estimates and judgments need audit attention

In an AUD question, an ASU usually points to assertions and audit evidence. If management applies a new lease standard, the auditor might search for omitted lease arrangements, recalculate lease liabilities, evaluate discount rates, and test disclosures. The ASU does not itself tell the auditor how to sample; it changes what the auditor must test.

Statements on Auditing Standards

Statements on Auditing Standards are issued by the AICPA Auditing Standards Board for audits of nonissuers. Current audit requirements are codified in AU-C sections. A SAS may introduce new requirements, amend existing sections, or clarify how nonissuer audits should be performed or reported.

SAS-based AUD questions usually ask about:

• professional responsibilities and skepticism
• audit planning and risk assessment
• sufficient appropriate audit evidence
• documentation
• communication with management or those charged with governance
• auditor reporting for nonissuer audits

Do not confuse a SAS with an ASU. A SAS changes the auditor’s responsibilities under GAAS. An ASU changes the accounting framework management applies.

Statements on Standards for Attestation Engagements

Statements on Standards for Attestation Engagements govern attestation services. Attestation engagements involve a practitioner reporting on subject matter or an assertion against suitable criteria. They are broader than audits of historical financial statements.

AUD candidates should associate SSAEs and AT-C sections with:

• examinations that provide reasonable assurance
• reviews that provide limited assurance
• agreed-upon procedures that report procedures and findings without an assurance conclusion
• SOC engagements and service-organization control reports
• compliance, pro forma, prospective financial information, or other subject matter

The trap is assuming every CPA report is an audit report. If the question says “examination,” “review,” “agreed-upon procedures,” or “SOC,” classify the engagement before choosing the answer.

SSARS and Unaudited Financial Statement Services

SSARS guidance matters in AUD because preparation, compilation, and review engagements are tested alongside audits and attest engagements. These engagements are not financial statement audits.

If the facts describe a review, do not choose procedures that assume audit-level evidence unless the question is asking about converting or expanding the engagement.

PCAOB Pronouncements and Rules

PCAOB standards apply to issuer audits and certain other covered engagements, including broker-dealer work. PCAOB materials include auditing standards, attestation standards, ethics and independence rules, quality control standards, and related releases or staff guidance.

For AUD, PCAOB references commonly signal:

• public-company audit context
• audit committee communication requirements
• engagement quality review
• issuer reporting format
• critical audit matters when applicable
• integrated audit responsibilities under AS 2201
• inspection and enforcement consequences for registered firms

PCAOB references should not be imported into a nonissuer audit unless the question gives a reason.

How Pronouncements Interact

One business event may trigger multiple standards families. Suppose a nonissuer adopts a new FASB accounting update for leases. Management applies the ASU in the financial statements. The auditor applies AU-C requirements to plan the audit, assess risk, obtain evidence, and report. If the same entity obtains a SOC report from a payroll processor, the user auditor evaluates whether the attestation report is relevant audit evidence.

The important distinction is role:

Common Pitfalls

• Treating an ASU as if it directly prescribed audit procedures.
• Applying PCAOB issuer-audit requirements to a nonissuer without a stated reason.
• Treating a compilation or preparation engagement as if it provides assurance.
• Assuming all SOC reports are relevant to financial statement assertions.
• Treating implementation guidance as stronger than the authoritative standard.
• Answering from the pronouncement acronym alone instead of the entity type, engagement type, and reporting objective.

Key Takeaways

• Classify the pronouncement before applying it.
• ASUs affect accounting; SASs affect nonissuer audits; SSAEs affect attestation engagements.
• SSARS guidance matters when the service is preparation, compilation, or review rather than audit.
• PCAOB standards matter when the engagement is an issuer audit or another PCAOB-covered engagement.
• In AUD questions, the right answer usually follows from matching the pronouncement type to the engagement type.
