Source: SEC EDGAR XBRL company facts — figures as reported in each period's original filing (structured data begins ~2008). EPS and other per-share figures are as reported and are not adjusted for later stock splits; a ⚑ marks a period where the reported share count changed by a large factor. Dollar figures in millions unless per-share. Line items a company never reports are omitted. Where a filer switched XBRL concepts, the successor concept is used and definitions can differ slightly (e.g. cash may include restricted cash; banks' revenue is net of interest expense; cost of revenue may exclude D&A; net income may be the amount available to common stockholders; debt issued/repaid may be net of issuance costs or include finance-lease obligations — each only where the original concept stopped being reported).
