Capital Returned to Shareholders
Cash spent on share repurchases and dividends per fiscal year, as reported on the cash-flow statement. Across FY2019–FY2021: $69.43K in buybacks.
Debt Profile
Annual debt figures are established from 10-K filings and updated by subsequent 10-Q and 8-K disclosures. Instrument balances are not summed into a company total unless the filing itself reports that total.
Revenue Breakdown
Annual revenue as the company disaggregates it in its own XBRL filings. Years a component wasn't reported show a dash.
Share mode is each component's slice of the reported components that year — issuers rarely tag every revenue dollar, so slices need not sum to total revenue.
