Meaning and calculation
Start with the annual filing when a headline leaves you wanting the full picture. A 10-K combines business and risk disclosures with audited financial statements; not every sentence in the filing is audited.

A hypothetical worked example
Hypothetical: A reader pulls an annual Form 10-K to examine Item 8 audited financial statements alongside Item 1A risk disclosures.
What can make this comparison misleading?
Read the auditor opinion and its scope. An audit provides reasonable assurance, not a guarantee of perfect accuracy, and filing with the SEC does not establish investment quality.
What to record beside the number
- The filing URL, document section and issuer identity.
- The reporting period, currency, units and whether the figure is reported or calculated.
- The exact formula and any missing inputs or differences in definitions.
