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.
