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. The first column is the trailing twelve months through the latest quarter. More on our methodology.
