Altman’s Z-Score is a financial metric used to predict the likelihood of a company entering bankruptcy within two years. Developed by Edward I. Altman in 1968, this score incorporates multiple financial ratios derived from a company’s financial statements. It is particularly used in corporate finance to assess the risk of financial distress.
Historical Context
Edward I. Altman, a Professor of Finance at New York University, developed the Z-Score model as a tool to predict corporate bankruptcy. It was created during a period where there was an increasing need for statistical models to predict business failures accurately.
Types/Categories
Altman’s Z-Score is used in various forms depending on the type of firm being analyzed:
- Original Z-Score: Applied to manufacturing firms.
- Z-Score for Private Firms: Modified version for private companies.
- Z’’-Score for Non-Manufacturing and Emerging Markets: Further adaptation for non-manufacturing and emerging market firms.
Key Events
- 1968: Introduction of Altman’s Z-Score.
- 1995: Introduction of Z’’-Score for non-manufacturing and emerging markets.
Detailed Explanation
Altman’s Z-Score is calculated using the following formula for public manufacturing companies:
Where:
- \( X_1 \) = Working Capital / Total Assets
- \( X_2 \) = Retained Earnings / Total Assets
- \( X_3 \) = Earnings Before Interest and Taxes (EBIT) / Total Assets
- \( X_4 \) = Market Value of Equity / Book Value of Total Liabilities
- \( X_5 \) = Sales / Total Assets
Interpretation:
- Z > 2.99: Safe Zone (low risk of bankruptcy)
- 1.81 < Z < 2.99: Grey Zone (some risk)
- Z < 1.81: Distress Zone (high risk of bankruptcy)
