How the Altman Z-score works
Z = 1.2 × working capital ÷ total assets + 1.4 × retained earnings ÷ total assets + 3.3 × EBIT ÷ total assets + 0.6 × market value of equity ÷ total liabilities + 1.0 × revenue ÷ total assets (Altman, 1968). The market value of equity is the close on the last trading day of the fiscal year times weighted basic shares.
Z″ = 6.56 × working capital ÷ total assets + 3.26 × retained earnings ÷ total assets + 6.72 × EBIT ÷ total assets + 1.05 × book equity ÷ total liabilities (Altman, Hartzell and Peck, 1995), the variant for non-manufacturing and asset-light companies.
| Zone | Z | Z″ |
|---|---|---|
| Safe zone | above 2.99 | above 2.60 |
| Grey zone | 1.81–2.99 | 1.10–2.60 |
| Distress zone | below 1.81 | below 1.10 |
