About the metric
What total debt means
Total debt measures a company’s reported interest-bearing borrowing obligations at a reporting-period end. It can include short-term borrowings, current maturities, long-term debt, and finance lease obligations when they are included in the company’s debt facts.
Calculation and source
SEC-reported and combined total debt
TickerStat uses a reported aggregate debt value when available. Otherwise, it combines non-overlapping current and noncurrent debt facts from SEC filings. Total liabilities are not treated as debt, and missing debt is not assumed to be zero. Fiscal periods can differ from calendar years, so exact period-end dates are included.
