![]() ![]() For the nonbankrupt firms, however, he chose corporations that had reported deficits during earlier years. A low score implies membership in one group, a high score implies membership in the other group, and a middling score causes uncertainty as to which group the subject belongs.įinally, to test the model, Altman calculated the Z Scores for new groups of bankrupt and nonbankrupt firms. ![]() The advantage to MDA is that many characteristics can be combined into a single score. This approach shows which characteristics in which proportions can best be used for determining to which of several categories a subject belongs: bankrupt versus nonbankrupt, rich versus poor, young versus old, and so on. To make his selection Altman used the statistical technique of multiple discriminant analysis. (For the bankrupt firms, he used the financial statements issued one year prior to bankruptcy.) His goal was to choose a small number of those ratios that could best distinguish between a bankrupt firm and a healthy one. The asset size of all corporations ranged from $1 million to $26 million…approximately $5 million to $130 million in 2005 dollars.Īltman calculated 22 common financial ratios for all 66 corporations. In 1966 Altman selected a sample of 66 corporations, 33 of which had filed for bankruptcy in the past 20 years, and 33 of which were randomly selected from those that had not. This article describes all three versions, which are easy to use in Excel. Later, Altman developed a modified version for private manufacturing firms and a second version for use by all businesses. This number, called the Z Score, is a general measure of corporate financial health. This model uses five financial ratios that combine in a specific way to produce a single number. Altman, then a financial economist at New York University’s Graduate School of Business, developed a model for predicting the likelihood that a firm would go bankrupt. But how can you predict which businesses are likely to go bankrupt and which are not?Ībout 40 years ago, Edward I. If you knew that a bankruptcy might occur in the next year or two, you could better protect yourself. Will your largest customer file next week? Will a critical vendor? A key investment? Your own employer? That number is 38% greater than the same period one year ago. Nearly 9,000 US companies filed for bankruptcy in the first quarter of 2008. “GM, Ford `On the Verge of Bankruptcy,’ Altman Says”, Bloomberg, July 22, 2008 The model shows that these companies are ‘on the verge of bankruptcy,’ he said.” “‘Both are in very serious shape and the markets reflect that,’ Altman, the creator of the Z-score mathematical formula that measures bankruptcy risk, said in an interview with Bloomberg Television. automakers, have about a 46 percent chance of default within five years, according to Edward Altman, a finance professor at New York University’s Stern School of Business. ![]()
