AICPA Code of Professional Conduct

Free CPA AUD (Auditing & Attestation) lesson in Ethics, Professional Responsibilities and General Principles. 33 min read, ~4,903 words.

Most common trap: "small direct interest, immaterial, not impaired." That answer is wrong; direct interests have no materiality exception.
