SOX Details
What It Is
Sarbanes-Oxley Act of 2002 (SOX) is a U.S. federal regulation enacted post-Enron scandals. It mandates internal controls over financial reporting (ICFR) for public companies, using a risk-based approach via frameworks like COSO.

Key Components
- 11 Titles covering PCAOB creation (Title I), auditor independence (Title II), certifications (Sections 302/906), ICFR assessments (Section 404), governance (Section 301), and penalties (Sections 802/806).
- Core on **key controlsentity-level, ITGC, financial close, access controls.
- Built on COSO principles; compliance via annual management reports and auditor attestations for accelerated filers.
Why Organizations Use It
Legal mandate for U.S. public firms; reduces fraud risk, builds investor trust, lowers capital costs. Strategic benefits: operational efficiency, M&A readiness, governance maturity. Exemptions for smaller/EGC filers retain management duties.
Implementation Overview
Top-down risk scoping, documentation, testing, remediation cycles. Applies to public issuers; phased (scoping, design, testing); requires PCAOB audits for Section 404(b). (178 words)
