Comprehensive Study Guide on Professional Auditing Standards, GAAS, and Regulatory Oversight
Historical Development and Sources of Auditing Standards
Early History and Auditing Regulation (Pre-1939):
- Auditing regulation was kept to a minimal standard prior to .
- The McKesson & Robbins case () served as a landmark catalyst for regulatory reform when auditors from PriceWaterhouse accepted management's false assertions regarding inventory and accounts receivable (A/R) without performing independent verification.
AICPA Auditing Standards Board (ASB):
- Formed to establish formal guidance following financial reporting failures.
- Issued Statements on Auditing Procedure from to
- Issued Statements on Auditing Standards (SAS) from to the present.
The Public Company Accounting Oversight Board (PCAOB):
- Established following major waves of financial reporting scandals in the early
- Issues Auditing Standards (AS) applicable specifically to public entities (issuers) from to the present.
Regulatory Standard-Setting Division Between Entity Types:
- Audits of Public Entities (Issuers that issue stocks to the general public):
- PCAOB Auditing Standards (AS) govern all current public entity audits.
- AICPA Statements on Auditing Standards (SAS) issued prior to April apply only if they have not been amended or superseded by PCAOB standards (referred to as Interim Standards).
- Audits of Nonpublic Entities (Non-issuers that do not issue stocks to the general public):
- All current Statements on Auditing Standards (SAS) issued by the Auditing Standards Board (ASB) of the AICPA govern nonpublic entity audits.
- PCAOB Auditing Standards are not applicable to nonpublic entities.
Hierarchy and Structure of Generally Accepted Auditing Standards (GAAS)
Components of GAAS and Their Authoritative Hierarchy:
- Fundamental Principles (Most Authoritative): Guide the overall conduct of audit engagements.
- PCAOB Auditing Standards and ASB Statements on Auditing Standards: Provide specific requirements supporting the fundamental principles.
- Interpretive Publications (Least Authoritative): Provide procedural guidance on the application of GAAS.
Objectives of GAAS Audits:
- Identify necessary qualifications and characteristics of auditors and guide audit execution.
- Obtain reasonable assurance about whether financial statements are free of material misstatement, whether caused by fraud or error.
- Report on financial statements and communicate auditor findings in accordance with established standards.
Alignment of Fundamental Principles with 10 Basic Auditing Standards:
- Responsibilities Principle (Replaces General Standards):
- Basic Standard 1: Training and proficiency.
- Basic Standard 2: Independence in mental attitude.
- Basic Standard 3: Due professional care.
- Core Responsibilities: Auditors must maintain competence and capabilities, satisfy ethical requirements (independence and due care), and exercise professional skepticism and professional judgment.
- Performance Principle (Replaces Standards of Field Work):
- Basic Standard 1: Planning and supervision.
- Basic Standard 2: Understanding of entity and environment to assess risk of material misstatement.
- Basic Standard 3: Obtain sufficient appropriate evidence.
- Core Performance Activities: Plan work and supervise assistants, determine and apply materiality levels, identify and assess risks of material misstatement, and obtain sufficient appropriate audit evidence to achieve reasonable assurance.
- Reporting Principle (Replaces Standards of Reporting):
- Basic Standard 1: Financial statements presented in accordance with GAAP.
- Basic Standard 2: Consistent application of GAAP (explicit report required only if inconsistent).
- Basic Standard 3: Adequacy of disclosures (explicit report required only if inadequate).
- Basic Standard 4: Express or disclaim an opinion.
- Core Reporting Activities: Express an opinion (or state that an opinion cannot be expressed) based on the financial statements' conformity with the applicable financial reporting framework.
Fundamental Principle of Responsibilities
Competence and Capabilities:
- Requires formal education, expertise, and practical auditing experience.
Ethical Requirements:
- Independence:
- Independence in Fact: The auditor's actual state of mind and unbiased mental attitude.
- Independence in Appearance: The perception of independence by informed third parties.
- Scenarios of Independence Failure:
- Auditor possesses independence in fact but lacks independence in appearance.
- Auditor possesses independence in appearance but lacks independence in fact.
- Potential Compromises to Independence:
- Financial relationships with audit clients.
- Managerial relationships with audit clients.
- The auditor-client revolving door issue (employment transitions between firms and clients).
- Due Professional Care:
- The level of diligence, skill, and care expected of a prudent auditor.
- Benchmark standard defined by the level of performance of a reasonable auditor acting in similar circumstances.
Professional Skepticism and Professional Judgment:
- Professional Skepticism:
- Defined as maintaining a questioning mind and a critical assessment of audit evidence.
- Presumption rule: The auditor assumes management is neither inherently dishonest nor perfectly honest.
- Operational requirement: All management assertions must be corroborated using objective evaluation of evidence.
- Professional Judgment:
- The application of relevant training, knowledge, and experience in making informed decisions throughout the audit.
- Necessary because audit decisions are rarely cut-and-dry.
- Overall quality of auditor professional judgment depends directly upon auditor competency and independence.
Fundamental Principle of Performance
Goal of Performance Principle:
- Provide reasonable assurance that financial statements are free of material misstatements.
Inability to Provide Absolute Assurance:
- Nature of Financial Reporting: Financial statements inherently rely on subjective estimates, management assumptions, and complex facts.
- Nature of Audits: Auditors rely on selective audit evidence and sampling methods rather than evaluating of transactions.
- Statutory Time and Cost Constraints:
- Audits must be completed within strict regulatory deadlines following fiscal year-end:
- Large Accelerated Filers:
- Accelerated Filers:
- All Other Public Entities:
- Audits are conducted within realistic financial cost considerations.
Major Activities of the Performance Principle:
- Planning and Supervision: Developing a comprehensive written audit plan and properly overseeing engagement team assistants.
- Materiality Determination: Establishing quantitative and qualitative thresholds that influence user decisions; considered continuously throughout the audit process.
- Risk Assessment: Gaining a detailed understanding of the entity and its environment (including internal controls) to evaluate risks of material misstatement and determine the nature, timing, and extent of substantive testing.
- Evidence Collection: Gathering appropriate and sufficient audit evidence.
Characteristics of Audit Evidence:
- Appropriateness (Quality of Evidence):
- Relevance: Evaluates whether specific evidence directly addresses the financial statement assertion being tested.
- Reliability: Measures trustworthiness based on evidence origin (ranked from highest to lowest quality):
- Auditor's direct personal knowledge (Highest reliability)
- External documentary evidence obtained from third parties outside the client
- Internal documentary evidence generated internally by the client (Lowest reliability)
- Sufficiency (Quantity of Evidence):
- Measures the volume of audit evidence collected (number of transactions or components evaluated).
- Dependent on internal control effectiveness:
- Effective Internal Controls Lower Control Risk Evaluates less audit evidence.
- Ineffective Internal Controls Higher Control Risk Evaluates more audit evidence.
- Detection Risk Relationship:
- Detection risk is the risk that audit procedures fail to detect an existing material misstatement.
- Detection risk decreases as the auditor collects higher quality (appropriate) and greater quantity (sufficient) audit evidence.
Fundamental Principle of Reporting
Reporting Directives:
- Formally express an opinion (or state that an opinion cannot be expressed) on the entity's financial statements.
- Evaluate financial statements against an established financial reporting framework.
- A financial reporting framework is the set of criteria used to measure, recognize, present, and disclose material items.
- Examples include U.S. Generally Accepted Accounting Principles (GAAP), International Financial Reporting Standards (IFRS), or special purpose frameworks (e.g., cash basis or tax basis accounting).
Major Sections of a Standard Public Company Auditor's Report:
- Title: Must explicitly state "Report of Independent Registered Public Accounting Firm".
- Addressee: Addressed to the Stockholders and Board of Directors of the client firm.
- Opinion on Financial Statements Section: Explicitly states the audited financial statement titles, dates, periods covered, and the formal opinion regarding fair presentation in conformity with GAAP.
- Basis for Opinion Section:
- Outlines management responsibility for financial statements and auditor responsibility for expressing an opinion.
- Identifies registration with the PCAOB and independence compliance under U.S. federal securities laws, SEC rules, and PCAOB regulations.
- States that audits were conducted in accordance with PCAOB standards and provided a reasonable basis for the opinion.
- Critical Audit Matters (CAMs) Section:
- Reports matters arising from the current audit communicated (or required to be communicated) to the audit committee that:
- Relate to accounts or disclosures material to the financial statements.
- Involved especially challenging, subjective, or complex auditor judgments.
- Note: Communication of CAMs does not alter the overall financial statement opinion or provide separate opinions on the individual CAMs.
- Engagement Sign-off Details: Signature of audit firm, city/state of audit office, report issuance date, and explicit disclosure of auditor tenure year.
Typology of Audit Opinions:
- Unmodified (used for nonpublic entities) / Unqualified (used for public entities): Financial statements present fairly in conformity with GAAP.
- Qualified: Financial statements present fairly in conformity with GAAP except for limited, specific items.
- Adverse: Financial statements do not present fairly in conformity with GAAP.
- Disclaimer: Auditors explicitly state that they do not express an opinion on the financial statements.
System of Quality Control and Firm Monitoring
Rationale for Quality Control:
- Auditing is an intangible service whose quality is unobservable to financial report users prior to suffering financial losses.
- Firms must establish systematic internal mechanisms to guarantee professional execution.
Purpose of Quality Control Systems:
- Provide the accounting firm with reasonable assurance that firm personnel comply with professional standards and legal/regulatory requirements while issuing appropriate reports.
Six Key Elements of Quality Control Systems:
- Leadership responsibilities for quality within the firm ("tone at the top").
- Relevant ethical requirements.
- Acceptance and continuance of client relationships and specific engagements.
- Human resources.
- Engagement performance.
- Monitoring.
PCAOB Monitoring & Inspection Mandates:
- Annual Inspection: Mandated for public accounting firms auditing more than public entities.
- Triennial Inspection: Mandated every for accounting firms auditing or fewer public entities.
- PCAOB Inspection Report Structure:
- Part I: Publicly reports identified audit performance deficiencies where the firm failed to obtain sufficient appropriate evidence to support its opinion.
- Part II: Addresses internal quality control deficiencies of the inspected firm; published publicly ONLY IF the firm fails to remediate Part I quality control issues within .
Empirical Deficiencies, Scandals, and Enforcement Cases
Madoff Ponzi Scheme Case:
- Approximately one year prior to being arrested for embezzling from investors, money manager Bernard Madoff stated: "In today's regulatory environment, it's virtually impossible to violate rules."

- Affected more than SEC regulatory filings between January and June .
- A prior regulatory review revealed a deficiency rate across firm files.
- Regulatory Sanctions & Penalties:
- Lifetime practice ban before the SEC for both the audit firm and Benjamin Borgers.

KPMG PCAOB Inspection Leak Scandal (–):
- Incident Overview: Scott Marcello (KPMG U.S. Vice Chair of Audit), four other partners, and one employee were terminated/departed due to illegal receipt of confidential PCAOB inspection target data.
- Mechanism: A former PCAOB employee hired by KPMG passed advance confidential inspection notices to KPMG personnel. KPMG internal staff alerted firm management, who subsequently reported the leak to the PCAOB.
- Enforcement Actions (January ):
- Five KPMG partners were charged with conspiracy and wire fraud.
- A sixth KPMG employee pled guilty to conspiracy and received a permanent ban from public financial statement auditing.
- Three of the six involved individuals were former PCAOB employees.
- Regulatory Response: PCAOB initiated formal internal reviews of its IT infrastructure, security controls, and ethical protocols.
