Financial crisis and its consequences are visible in the capital adequacy of many commercial banks, which indicates that the approach banks took to assess credit risk was not sufficiently sophisticated. This article discusses practical methods of insolvency risk modeling for enterprises. In this paper, the authors analysed the accuracy of ten models developed by foreign authors to assess insolvency risk, which were validated on the database of Latvian companies. Authors have shown that models developed on historical data for foreign companies are less accurate than the model developed on the basis of financial indicators of Latvian companies. The authors developed a three-factor model that estimates probability of default of Latvian enterprises based on historical data for 1,272 enterprises using binary logistic regression analysis.
