Each year's change is the diluted weighted average share count against the year before, with stock splits taken out; the headline change compares the two ends of the span on one basis. Buybacks and stock pay are added up over the same years. Buybacks that only offset stock pay leave the count flat: both are shown, no verdict. How

Each bar is one fiscal year; its colours add up to what the cash flow statement says the company spent on each line, and the line across it is that year's operating cash flow. Spending above the line was paid from new debt, shares sold or cash on hand. A bar part links to the 10-K it comes from. A line the company did not report is left out, not estimated, so the shares are of operating cash only and can add up to more or less than 100%. Debt repaid is the gross amount, so refinanced debt is counted each time it is repaid. A reading aid, not a grade: Tickdelta does not say whether a split was good. Banks and insurers are left out.

Shares and average price are the numbers in the 10-Q table, row by row; "shares × price" is our multiplication of the two. A row with a price of "-" is an accelerated repurchase paid up front, where the 10-Q does not give a price yet. A 10-Q that counts shares in millions gives a rounded number, shown as "about". Shares withheld for employees' taxes are not in this table. A month that no 10-Q table gives, or that this page could not read with confidence, is not shown.
