Ethics, Professional Responsibilities, and Auditor Independence

This chapter covers the ethical and professional constraints that control audit work before any procedure begins. Many AUD questions hinge on whether the auditor may act, how skepticism should be applied, and what professional failures create independence or liability problems.

In This Chapter

• Applying the AICPA Code of Professional Conduct in Audit Work introduces the ethical framework behind CPA responsibilities.
• Comparing Auditor Independence Requirements Across AICPA, PCAOB, SEC, GAO, and DOL compares the major independence regimes.
• Using Professional Skepticism and Judgment Throughout the Audit explains the mindset expected in evidence evaluation and decision-making.
• Understanding Auditor Legal Liability and Malpractice Exposure covers exposure when standards are not met.
• Working Through Audit Ethics Dilemmas and Practice Cases applies the rules in scenario form.

How to Use This Chapter

• Read this chapter early because ethics and independence affect every later engagement decision.
• Focus on the facts that impair independence or require a stronger skeptical response.
• Revisit it whenever an AUD question turns on professional behavior rather than evidence mechanics.
