SEC
/ say the letters: S-E-C /
Picture a marketplace where you can buy a tiny slice of a company. You would only feel safe handing over your money if you trusted that the company had told the truth about itself. The SEC is the US government referee that exists to keep that marketplace honest — it polices public companies so that investors get accurate, timely information and are protected from fraud.
SEC stands for the Securities and Exchange Commission, a US federal agency created in 1934 after the 1929 stock-market crash. Any company that sells shares to the public in the US must file financial reports with the SEC — for example an annual report on Form 10-K and quarterly reports on Form 10-Q — prepared under US GAAP and usually audited by an independent firm. The SEC has the legal authority to require these disclosures, to investigate, and to bring enforcement actions. Importantly, the SEC has the power to set US accounting standards itself but has largely delegated that job to the FASB, while keeping ultimate oversight.
The SEC matters because it is the bridge between the accounting rulebook and real legal consequences: GAAP becomes mandatory for public companies largely because the SEC requires it. It also oversees the body that regulates auditors (the PCAOB), created after the Enron and WorldCom scandals. Two honest limits: the SEC governs public companies and securities markets in the US — private companies and other countries fall outside its reach — and it cannot guarantee no fraud ever happens; it can only set rules, inspect, and punish after the fact.
A US public company quietly inflated its sales for two years. Investors did not catch it, but the SEC opened an investigation, forced the company to restate its filed financial statements, and fined it. The SEC could act because every public company must file GAAP statements with the agency — that filing is what gave regulators something to check.
The SEC turns the accounting rulebook into something with real legal force for public companies.
The SEC sets the requirement to follow GAAP but mostly delegates writing the rules to the FASB. And it is a US-only regulator: it does not govern private companies or markets in other countries, each of which has its own watchdog.
