Dividends per share over the trailing 365 days by ex-date · buyback figures as last reported in SEC filings ("spent" derived as authorized − remaining; when several programs run concurrently, authorized is their combined total per the newest filing) · components shown separately — trailing-year buyback spend isn't tracked, so no combined shareholder yield is derived.
