Form 10-K
Also called: 10-K, annual report, 10K filing
The 10-K is the comprehensive annual report US public companies file with the SEC — audited statements, business description, risk factors, MD&A and legal proceedings. Unlike the glossy annual report sent to shareholders, it's a legal document with liability attached to every statement. The risk factors section and the notes are where the substance is, and both are freely available on EDGAR.
