Unit
- Primary objective: An audit expresses an opinion on whether financial statements are free from material misstatement, whether due to fraud or error, following applicable financial reporting framework.
- Scope definition: Audit scope covers examining accounting records, internal controls, and evidence supporting account balances, disclosures, and transactions over a fiscal period.
- Stakeholder relevance: Investors, creditors, regulators, and the public rely on audited statements for informed decisions, making audit independence and objectivity paramount.
- Materiality concept: Misstatements are considered material if they could influence economic decisions of users, guiding the extent of audit procedures.
- Reasonable assurance: Auditors provide high but not absolute assurance, as inherent limitations exist such as judgment, sampling, and management override.
- Audit vs. review: A review provides limited assurance through inquiry and analytical procedures, while an audit provides reasonable assurance with testing.
- Regulatory context: Public company audits in the US must follow PCAOB standards; private audits follow AICPA or IAASB standards depending on jurisdiction.
- Non-assurance services: Compilations and agreed-upon procedures engagements do not provide assurance and serve specific user needs.
- International framework: The International Standards on Auditing (ISA) issued by IAASB are adopted in over 100 countries, promoting global consistency.
- Risk assessment: Auditors identify and assess risks of material misstatement at the financial statement and assertion levels, then design responses that address those risks through targeted procedures and tests.
- Audit evidence: Sufficient appropriate evidence is obtained through inspection, observation, confirmation, recalculation, reperformance, and analytical procedures to support the opinion and reduce audit risk to an acceptably low level.
- Professional skepticism: Auditors maintain a questioning mind and critically assess audit evidence, being alert to conditions that may indicate possible misstatement due to fraud or error throughout the engagement.
- Internal control evaluation: Understanding and testing the design and implementation of internal controls helps auditors determine the nature, timing, and extent of substantive procedures needed for each material account.
- Engagement acceptance: Before accepting a new client or continuing an existing relationship, auditors evaluate integrity of management, independence requirements, competence, and ability to perform the engagement in compliance with ethical standards.
Regulatory Requirement
Regulation: SEC, PCAOB, AICPA, IAASB
Public company audits in the U.S. are subject to oversight by the Public Company Accounting Oversight Board (PCAOB), which establishes auditing standards and conducts inspections. Private company audits follow AICPA Statements on Auditing Standards (SAS). Internationally, the IAASB issues ISAs which many jurisdictions adopt or use as a benchmark. Compliance with these frameworks ensures audit quality and consistency.
