The 17-year record

17 fiscal years

Every figure from documents filed with the SEC · USD

EPS, diluted, dividend per share and shares outstanding are shown without shading, and a vertical line marks the year the share count changed — the series crosses a large, unexplained change in share count, so the years on either side are not on a comparable scale.
