NEW YORK (TheStreet) -- The financial crisis stoked investor fears that bankruptcy was imminent for a number of companies, no matter how big or small. Luckily for investors, there is a way to examine certain financial metrics to see which companies are least likely to declare bankruptcy.The Altman Z-score, a formula developed by New York University professor Edward Altman in 1968, measures several aspects of a company's financial health to forecast the probability of that company entering bankruptcy within two years. The formula was found to be approximately 80% to 90% accurate in predicting bankruptcy on samples of distressed firms one year prior to the event by examining working capital, retained earnings and other financial inputs, according to Altman's study.
