The subject of the paper is solving the problems arising from the use of highly synthesized financial statements. The paper presents a model by which highly synthesized financial data can be used for the needs of reorganization in bankruptcy management. Financial and accounting data are frequently synthesized, i.e. organized in such a way that they largely hide the details of the business. The act of synthesis is needed in order a general picture of a company's business to be created. Financial statements such as balance sheets and income statements represent typical examples. In the paper, there are used several research methods to formulate the models for the efficient use of highly synthesized financial statements. The basic method used in the research was the case study method, then the modelling method, and, as an auxiliary method, there was used the documentation analysis method. The case study analyzed the main indicators being important for the bankruptcy. We analyzed six companies which were in the process of reorganization in bankruptcy, and the analysis identified common characteristics served as the starting points for the next method. The next method used was the modelling method. This method was a logical continuation of the previous method by which a new model was formulated. As a tool in modelling, there were used the block diagrams, which graphically showed all important elements and relations. The auxiliary method used was the documentation analysis method. It is a historical method and an integral part of the previous two methods. The aim of the paper is to increase the efficiency of the use of highly synthesized financial statements in bankruptcy management.
