Share-repurchase activity from the company's own XBRL filings — cash spent buying back common stock per fiscal year and per recent quarter, share counts where the company tagged them, and the buyback program's authorization. Amounts come exclusively from tagged SEC data, so periods a company never tagged show no figure.
