SEC (Securities and Exchange Commission)

The SEC is the federal regulator that requires public companies to file audited financial statements, sets auditor independence rules for issuers, and oversees the PCAOB.

CORAA TeamUpdated November 5, 2026

Definition

The US Securities and Exchange Commission (SEC) administers the federal securities laws. Public companies register securities and file periodic reports such as Form 10-K, which includes audited financial statements prepared under US GAAP. Regulation S-X sets presentation and auditor independence requirements. The SEC oversees the PCAOB, approves its budget and standards, and can discipline auditors who appear before it.

Why it matters in an audit or review

SEC rules add to audit work for issuers: auditor independence under Rule 2-01 of Regulation S-X, audit committee pre-approval of services, partner rotation, and filing deadlines tied to company size. Private companies are outside these rules unless they plan to file with the SEC, such as in an IPO, where past statements may need re-audit under PCAOB standards.

Example

Illustrative: a company plans to go public. Its prior auditor's reports followed AICPA standards, so the company engages a PCAOB-registered firm to re-audit the periods included in the registration statement.

Common mistakes

Assuming SEC independence rules match the AICPA rules.

FAQ

Does the SEC set accounting standards?

It has authority to, but it relies on FASB and recognizes FASB standards for issuers.
