Definition
The Altman Zscore (ZScore) is a formula for determining the probability that a private company is heading for financial failure. The formula is made up of liquidity, solvency, profitability, leverage, and activity ratios. Each ratio is given a weighting, culminating in the calculation of the ZScore.
