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 ratios and per-share amounts. Cash and investments adds short-term and long-term marketable securities to cash. Debt due within a year is the borrowings that are not already in long-term debt. Total debt is those borrowings plus lease liabilities. Net cash is cash and investments minus total debt. Return on equity and return on assets divide the trailing twelve months of net income by the balance on that date. Debt to EBITDA uses the trailing twelve months of EBITDA. The first column is the latest balance sheet when it is newer than the latest fiscal year. More on our methodology.
