Altman Z-score

The Altman Z-score is an essential financial tool for evaluating a company’s bankruptcy risk, a key indicator of financial health developed by Professor Edward Altman in the 1960s. This predictive model assists investors, analysts, and business owners in gauging a company’s financial stability using a simple formula that includes working capital, retained earnings, and total assets. With its easy-to-apply nature, the Altman Z-score is widely used to assess public and private company risks and identify early warning signals for financial distress.

What is the Altman Z-Score?

The Altman Z-score is a financial formula designed to predict a company’s likelihood of bankruptcy within two years. It combines several ratios related to a company’s profitability, liquidity, and solvency into a single score. Higher scores generally indicate greater financial stability, while lower scores reveal elevated risk. The Altman Z-score formula is especially valuable for evaluating publicly traded companies in manufacturing but has adapted variations for private and non-manufacturing businesses.

Formula and Calculation of the Altman Z-Score

The Altman Z-score formula is as follows:

Z = 1.2 (X1) + 1.4 (X2) + 3.3 (X3) + 0.6 (X4) + 1.0 (X5)

Each variable represents a key financial ratio:

1. X1 = Working Capital / Total Assets: Reflects liquidity and a company’s ability to cover short-term obligations.
2. X2 = Retained Earnings / Total Assets: Indicates the accumulated profits and a measure of stability.
3. X3 = Earnings Before Interest and Tax (EBIT) / Total Assets: Measures operating efficiency and asset utilization.
4. X4 = Market Value of Equity / Book Value of Total Liabilities: Assesses solvency and the market’s valuation of the firm’s debt.
5. X5 = Sales / Total Assets: Gauges asset efficiency and turnover.

The result, Z, indicates financial health:

• Z > 2.99: Safe Zone – Low risk of bankruptcy
• 1.81 < Z < 2.99: Grey Zone – Moderate risk
• Z < 1.81: Distress Zone – High risk of bankruptcy

Step-by-Step Example of Altman Z-Score Calculation

Let’s consider a hypothetical company, XYZ Corp, with the following data:

• Working Capital: $200,000
• Total Assets: $1,000,000
• Retained Earnings: $150,000
• EBIT: $120,000
• Market Value of Equity: $400,000
• Book Value of Total Liabilities: $300,000
• Sales: $600,000

Applying the formula:

1. X1 = 200,000 / 1,000,000 = 0.2
2. X2 = 150,000 / 1,000,000 = 0.15
3. X3 = 120,000 / 1,000,000 = 0.12
4. X4 = 400,000 / 300,000 = 1.33
5. X5 = 600,000 / 1,000,000 = 0.6

Thus, Z = 1.2(0.2) + 1.4(0.15) + 3.3(0.12) + 0.6(1.33) + 1.0(0.6) = 2.92

In this case, XYZ Corp falls into the Grey Zone, indicating a moderate risk of bankruptcy.
