About the metric
What working capital means
Working capital is the difference between current assets and current liabilities. It provides a snapshot of short-term operating liquidity, although negative working capital can be normal for some business models and the measure is often not meaningful for banks.
Calculation and source
How working capital is calculated
TickerStat calculates working capital as reported current assets minus reported current liabilities at the same balance-sheet date. Missing current classifications are not assumed to be zero. Fiscal periods can differ from calendar years, so exact period-end dates are included.
