How each year is computed
Close at fiscal year end / diluted earnings per share
P/E, free cash flow yield and EV to EBIT set each filed year against the close on or within a week before that fiscal year's end. The price archive here is about five years deep, so older years of those three read n/a. Per-share figures and share counts are put on today's share count after a confirmed split, the basis the price archive is kept on.
