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 — paired with the company's at-the-market (ATM) equity offering programs, the dilution side of the same picture. Repurchase amounts come exclusively from tagged SEC data; program figures with no tagged equivalent (untagged authorizations and all ATM figures) are read from the filing's own text and shown only after verification.
