* The fourth quarter is the full year less the first three quarters, because the company files the year and not the quarter on its own. 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.

Income statement lines from each year's 10-K, the year linked to its filing; TTM is the sum of the last four quarters. 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. † The year as the company last restated it in a later filing; rest on a figure for the one first filed. EPS is as filed.

Buybacks and dividends are the cash paid in the year, from the cash flow statement; the dividend per share is as declared. Diluted shares are the weighted average for the year; a falling count is the buybacks net of issuance. TTM sums the last four quarters; the share counts are the latest quarter's.

Compounded growth is the latest fiscal year over the year that many years earlier, annualised; the TTM column is the last four quarters over the four before. Return on equity is net income over shareholders' equity at each year end, averaged over the window (the TTM column is the latest year alone); equity is the parent's shareholders' equity as tagged in the 10-K. Arithmetic on filed numbers, nothing forecast.
