How these figures are calculated
Quarterly columns are single-quarter amounts. When a 10-Q reports only a year-to-date total, as cash flow statements do, the quarter is that total minus the previous quarter's year-to-date total. The fourth quarter is the annual report's full year minus the first nine months. A column marked YTD is a year-to-date total, shown when the earlier report needed for the single quarter is missing. USD in millions, except per-share amounts and margins. Weighted average shares are in millions. Interest expense and finance costs are positive costs. A negative amount on a gain (loss) or income (expense) line is a loss or an expense. EBITDA is operating income plus depreciation and amortization. Interest coverage is operating income divided by interest expense. More on our methodology.
