Free cash flow is operating cash flow less capital expenditure; the effective tax rate is income tax over pre-tax income; margins are the line over revenue. Gross profit is revenue less cost of revenue, and operating income is revenue less the company's own total costs, where the statement does not print those lines. Those four are arithmetic on the filed numbers; everything else is as filed. Money is in $ million as the company files it, or in $ billion by the switch above the tables; per share figures and share counts are as they are.Cash flow and capital returned
