Form 10-K

What Is a Form 10-K?

A Form 10-K is an annual report that most U.S. public companies must file with the Securities and Exchange Commission (SEC). It gives investors a detailed, standardized look at a company's operations, finances, and risks over its most recent fiscal year. The requirement comes from the Securities Exchange Act of 1934, and the SEC makes filings publicly available through its EDGAR database.

Because the SEC prescribes what a 10-K must cover, it is more detailed and consistent than the annual report to shareholders that many companies send to their investors.

What a 10-K Contains

A typical 10-K is organized into numbered parts and items. Common sections include:

• A description of the company's business, products, markets, and competitors
• Risk factors that could affect the business
• Legal proceedings and descriptions of key properties
• Management's discussion and analysis (MD&A), in which management explains results and trends in its own words
• Audited financial statements, including the balance sheet, income statement, cash flow statement, and accompanying notes

The financial statements are audited by an independent accounting firm. The narrative sections are not audited in the same way, so readers should weigh them with that in mind.

Why It Matters to Investors

The 10-K is one of the most complete public sources of information about a company. Investors often read the risk factors and MD&A to understand how management views the business and what could go wrong. The financial statements can also be used to calculate measures such as financial ratios, which help in comparing companies.

Limitations

A 10-K is backward-looking. It reports past results and includes management's own assessments, which may be overly optimistic. It is also published months after the fiscal year ends, so the information can be dated by the time it is read. For this reason, investors often review it alongside more recent filings, such as the quarterly reports companies file on Form 10-Q.
