* Worked out from the filings rather than stated in them: Q4 is the full year less the first nine months.
Per-share figures are as filed. The filings show no stock split in these periods.
EPS growth is left out where the share count moved enough to suggest a split the filings do not show. Growth rates need a positive starting figure. CAGR is compound annual growth between fiscal years. The CSV holds every period on file, in full figures, from the same SEC filings.
