The impact of changes in the business environment and normative basis of financial reporting on the presented power of measure of financial performance of the company

Until today despite the many changes that have occurred, particularly in the last two decades, in the business environment and operations of companies, more than a century old ratio analysis proved to be a simple and quick way of identifying the quality of their financial position and successfulness. The beginning of the application of „mixed” basis of financial reporting brought change in the content of results and in the equity due to the application of the fair value. The circumstances in which the result includes unrealized gains whose realization can be expected in a relatively short time, turned a realized gain out of the concept of historical cost into the result that the company would achieve if, until the sale of financial assets that are measured at fair value per result, there would not be any changes in their fair value. As such expectations are unrealistic it is useful to determine the share of unrealized gains/losses in the result. There is also a similar but stronger need when it comes to the equity, which includes unrealized gains whose realization will occur in a longer period, so there is higher probability that changes in the fair value of assets and liabilities which are measured at fair value per other total result will happen. Because of this measures of financial performance, which are determined on the basis of the stated parameters, can have different values and interpretations. The need to adapt the performance measures to the needs of investors and creditors imposed the requirements for establishing new ones and using non-financial performance measures together with the selected measures of financial performance
