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.

Each quarter as filed, linked to its filing.

Money is in $ million as the company files it, or in $ billion by the switch above the tables; per share figures and the share count are as they are. 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. Cash flow lines filed year to date are the difference between two filings. Shares outstanding are at the period end where the balance sheet tags them, otherwise the count on the filing's cover page. A derived fourth-quarter EPS is left blank when a split in the year makes the arithmetic meaningless.
