Altman Z-Score Explained
The Altman Z-Score is a financial model designed to estimate the probability of corporate financial distress using accounting-based ratios.
What the Z-Score measures
The model combines profitability, leverage, liquidity, solvency, and efficiency indicators into one score. It was originally developed for manufacturing companies, but variations are often used as a broad distress-risk signal.
General interpretation
- Higher score: generally indicates lower financial distress risk.
- Lower score: may indicate elevated financial pressure.
- Middle zone: requires deeper review because the signal is less clear.
Why it matters
The Z-Score can help identify companies where balance-sheet risk may be rising. It is particularly useful when paired with debt levels, interest coverage, cash flow, and profitability trends.
Limitations
The Altman Z-Score is not a complete credit model and should not be treated as a prediction guarantee. It can be less reliable for financial firms, early-stage growth companies, and businesses with unusual accounting structures.
