Area I: Ethics, Professional Responsibilities and General Principles
This area covers the rules that decide whether a CPA may take and keep an engagement: independence under the AICPA Code, SEC and PCAOB rules, GAO and Department of Labor requirements, professional skepticism, engagement terms, documentation, communications with governance, and the firm's quality management. Many questions depend on the entity type, so read whether the stem says issuer, nonissuer, government, or employee benefit plan before answering.
Independence under the AICPA Code
The AICPA Code sorts independence problems into threats: adverse interest, advocacy, familiarity, management participation, self-interest, self-review, and undue influence. A member identifies threats, evaluates their significance, and applies safeguards, but some relationships are impairments that no safeguard can fix. The most tested are direct financial interests, unpaid fees, loans, and nonattest services where management does not take responsibility. Fee arrangements and the handling of confidential client information fall under separate rules in the Code.
SEC, PCAOB, GAO and DOL requirements
Auditors of issuers follow SEC Rule 2-01 and PCAOB rules, which are stricter than the AICPA Code in several places. The SEC lists non-audit services that impair independence, requires partner rotation, and imposes a cooling-off period before audit team members join the client in financial reporting roles. Government auditors follow the Yellow Book, and plan auditors must meet the Department of Labor's independence bulletin. Know which rule set applies to which client.
Skepticism, engagement types and terms
Professional skepticism is an attitude, and professional judgment is the application of training and experience to decisions; standards also name specific biases that undermine both. The level of assurance separates the engagements: audits and examinations give reasonable assurance, reviews give limited assurance, and compilations and preparation engagements give none. Before accepting an audit, the auditor confirms the preconditions, agrees on terms in writing, and makes inquiries of any predecessor auditor.
Documentation, communications and quality management
Audit documentation must let an experienced auditor with no previous connection to the engagement understand the work, the findings, and the significant judgments. Deadlines for assembling and retaining documentation differ between nonissuer and issuer audits. Communications with those charged with governance cover the planned scope and timing of the audit, significant findings, and internal control deficiencies. Quality management standards place responsibility on the firm and on the engagement partner.
