Economic crisis has greatly affected the Croatian economy in things such as fall in investment, low growth in private consumption, the decline in real wages, high public debt, high illiquidity and insolvency of businesses. If the crisis is poorly managed and if management fails to take measures to restructure and improve the business, the company threatens bankruptcy. The aim of the research was based on 10 selected joint stock companies listed on the stock exchange to examine relations crisis and business performance that are measured in the Z-score and BEX index summarized. Also, the aim was also to predict, calculate and determine the (lack of) success of the company, by using the model to estimate the company's business excellence based on financial indicators, on the basis of data from the financial statements that are readily available to all external users. In this research named "The crisis and business performance of the company measured by Z-score and BEX index", the theme of a business crisis and aggregate indicators of early warning (not) the success of their business ,has been proccesed. Two hypotheses were set: "Z-score is a good predictor of failure of business enterprises" and "BEX index predicts performance of the business success of the company in the near future". Both theses have been accepted as accurate.
