Altman Z-score

The coefficients were 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 estimation was originally based on data from publicly held manufacturers, but has since been re-estimated based xnd other datasets for private discrjminant, non-manufacturing and service companies.

The original Z-score 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, analysid of which had filed for bankruptcy under Chapter 7.

Altman Z-score – Wikipedia

Fisher, Ronald Aylmer Altman applied the statistical method of discriminant analysis to a dataset of publicly held manufacturers. In the s and on, Mervyn and others had collected matched samples and assessed that various accounting ratios appeared to be valuable in predicting bankruptcy.

Altman’s primary improvement was to apply a statistical method, discriminant analysis, which could take into account multiple variables simultaneously.

Altman’s work built upon research by accounting researcher William Beaver and others.

This is because of the opacity of financial companies’ balance sheets and their frequent use of off-balance sheet items. This page was last edited on 7 Novemberat 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. Altman’s Z-score is a customized version of the discriminant bkj technique of R. Beaver applied this method to evaluate the altmaj of each of several accounting ratios based on univariate analysis, using each accounting ratio one at a time.

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.
