How these figures are calculated
Annual columns are full-year amounts from the annual report (Form 10-K, 20-F, or 40-F). If a company restates a year, the latest filed number is shown. 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.
