Methodology

Every figure on this page traces back to SEC EDGAR XBRL company-facts filings (FFIV CIK 0001048695), tagged with the us-gaap and dei taxonomies. The only exception is the live market cap tile, which uses the current share price × shares outstanding from a market quote. Historical share prices come from our total-returns daily history (split-adjusted); historical market caps are calibrated against today's share count to correct for SEC retroactive split restatements.

For the exact XBRL concepts and formulas, see the methodology reference for net worth, debt, cash, market cap, enterprise value, net debt, shares outstanding, and the historical-market-cap calibration.
