Publicly traded companies initially disclose their risk factors to the SEC through their S-1 filings as part of the IPO process. Additionally, companies must provide a complete list of risk factors in their Annual Reports (Form 10-K) or (Form 20-F) for “foreign private issuers”. Quarterly Reports also include a section on risk factors (Form 10-Q) where companies are only required to update any changes since the previous report. According to the SEC, risk factors should be reported concisely, logically and in “plain English” so investors can understand them.
