Choose the ratio and keep its units visible
Start with reported cash and cash equivalents. Marketable securities are not automatically cash equivalents; include them only in a separately labeled expanded-liquidity measure after considering saleability and restrictions. State whether debt includes leases and whether current maturities are already in total debt.
| Measure | Formula | What to state |
|---|---|---|
| Cash / total debt | Cash and equivalents / defined total debt | Same balance-sheet date; unrestricted or reported cash |
| Cash / short-term debt | Cash and equivalents / debt due within the selected horizon | Current debt is not all current liabilities |
| Operating cash flow / debt | CFO for a stated period / debt | Annual or TTM CFO; ending versus average debt |
| Debt / operating cash flow | Debt / positive annual CFO | Static multiple; spending and future cash flows are not modeled |
