William Beaver’s work, published in andwas the first to apply a statistical method, t-tests to predict bankruptcy for a pair-matched sample of firms. In the s and on, Mervyn and others had collected matched samples and assessed that various zltman ratios appeared to be valuable in predicting discruminant.

From about onwards, the Z-scores gained wide acceptance by auditors, management accountants, courts, and database systems used for loan evaluation Eidleman.

The formula may be used to predict the probability that a firm will go into bankruptcy within two years. Fisher, Ronald Aylmer The Z-score qnalysis multiple corporate income and balance sheet values to measure the financial health of a company. This znd because of the opacity of financial companies’ balance sheets and their frequent use of off-balance sheet items.


The Z-score is a linear combination of four or five common business ratios, weighted by coefficients. The estimation was originally amd on data from publicly held manufacturers, but has since been re-estimated based on other datasets for private manufacturing, non-manufacturing and service companies. Retrieved from ” https: Neither the Altman models nor other balance sheet-based models are recommended for use with financial companies.

Altman Z-score – Wikipedia

From Wikipedia, the free encyclopedia. Altman applied the statistical method of discriminant analysis to a dataset of publicly held manufacturers. Altman’s work built upon research by accounting researcher William Beaver and others.

Altman’s Z-score is a customized version of the discriminant analysis technique of R. For the concept of standard score in statistics, often called the z-score, see Standard score.

Altman’s primary improvement was to apply a statistical method, discriminant analysis, which could take into account multiple variables simultaneously. Later variations by Altman were designed to be applicable to privately held companies the Altman Z’-Score and non-manufacturing companies the Altman Z”-Score.

The coefficients analyzis estimated by identifying a set of firms which had declared bankruptcy and then collecting a matched sample of firms which had survived, with matching by industry and approximate size assets. The Z-score formula for predicting bankruptcy was published in by Edward I. Prepared for “Credit Rating: Views Read Edit View history.

There are market-based formulas used to predict the default of financial firms such as the Merton Modelbut these have limited predictive value because they rely on market data fluctuations of share and options prices to imply fluctuations in asset values to predict a market event default, i. The original Discriminxnt formula was as follows: Z-scores are used to predict corporate defaults and an easy-to-calculate control measure for the financial distress status of companies in academic studies.

The original data sample consisted of 66 firms, half of which had filed for bankruptcy under Chapter 7.

Beaver applied this method to evaluate the importance of each of several accounting ratios based on univariate analysis, using each accounting ratio one at a time.
