Red Flags & Footnotes
Where companies hide the most important information
The most critical information in any 10-K is often buried in the footnotes. The financial statements give you the headline numbers; the footnotes explain how those numbers were derived, what assumptions support them, and what the company is required to disclose but would rather not emphasize. Accounting policy changes, off-balance-sheet liabilities, segment-level economics, contingent legal risks, related-party transactions, derivative exposures — all live in footnotes.
Most retail investors never read them. The professionals who do find the material that doesn't show up in any spreadsheet. A typical large-cap 10-K has 25-50 footnotes, organized by topic.
The most important ones for fundamental analysis: Significant Accounting Policies (Note 1, usually) describes how the company recognizes revenue, depreciates PP&E, values inventory, amortizes intangibles. Segment Information breaks results by reportable business unit. Debt Maturities shows when bonds and term loans come due.
Related-Party Transactions discloses material insider arrangements.
