Z-Score

What is the Z-Score?§

The Z-Score, also known as the Altman Z-Score, is a financial model formulated by Edward I. Altman in 1968 to predict the likelihood of a business failure. It uses multiple discriminant analysis to evaluate the financial health of a company by applying β coefficients to a series of ratios derived from an organization’s financial statements. In other words, the Z-Score quantifies the financial viability and distress probabilities of a firm. A UK-based variant was created by Richard J. Taffler in 1983.

Key Components of Z-Score§

The Altman Z-Score is calculated using the following formula for a publicly traded manufacturing company:

$$Z = 1.2T_1 + 1.4T_2 + 3.3T_3 + 0.6T_4 + T_5$$

Where:

• $T_1$: Working Capital / Total Assets
• $T_2$: Retained Earnings / Total Assets
• $T_3$: Earnings Before Interest and Taxes (EBIT) / Total Assets
• $T_4$: Market Value of Equity / Total Liabilities
• $T_5$: Sales / Total Assets

Z-Score Interpretation§

• Above 2.99: The company is considered “safe” from financial distress.
• Between 1.8 and 2.99: The company is in a “grey zone” or borderline of financial distress.
• Below 1.8: The company is likely to be heading toward bankruptcy.

Examples§

1. Company XYZ: XYZ Inc., a manufacturing company, reports the following ratios based on its latest financial statements:

   • Working Capital / Total Assets: 0.2
   • Retained Earnings / Total Assets: 0.3
   • EBIT / Total Assets: 0.12
   • Market Value of Equity / Total Liabilities: 0.6
   • Sales / Total Assets: 2.5

   Using the Z-Score formula: $$Z = 1.2(0.2) + 1.4(0.3) + 3.3(0.12) + 0.6(0.6) + 1(2.5) = 3.024$$ XYZ Inc. is considered “safe” from financial distress.

2. Company ABC: ABC Ltd., has the following ratios:

   • Working Capital / Total Assets: 0.05
   • Retained Earnings / Total Assets: 0.1
   • EBIT / Total Assets: 0.04
   • Market Value of Equity / Total Liabilities: 0.15
   • Sales / Total Assets: 1.0

   Using the Z-Score formula: $$Z = 1.2(0.05) + 1.4(0.1) + 3.3(0.04) + 0.6(0.15) + 1(1.0) = 1.382$$ ABC Ltd. is likely heading toward financial distress.

Frequently Asked Questions (FAQs)§

What are the limitations of the Z-Score?§

• Industry Specificity: The original Z-Score was tailored for manufacturing firms. Its reliability may decrease when applied to other industries.
• Period Sensitivity: Financial ratios change over time, which may affect the accuracy of the Z-Score.
• Complexity: Understanding and applying the formula correctly requires comprehensive knowledge of financial statements.

Can the Z-Score predict future financial performance?§

While the Z-Score is a useful tool for assessing financial distress, it is not a definitive predictor of future performance. It should be used in conjunction with other financial analysis tools and models.

What is the Taffler Z-Score?§

The Taffler Z-Score, introduced by Richard J. Taffler in 1983, is a UK-specific model designed to predict corporate failure. It adapts the principles of Altman’s model for the UK market.
