Impact of International Financial Reporting Standards （IFRS） Adoption on Key Financial Ratios＂ The Case of the Czech Republic

This contribution analyzes the impact of new International Financial Reporting Standards （IFRS） reporting rules on financial ratios prepared in the Czech companies. Using a sample of 16 Czech firms, we attempt to measure the scope and size of the differences in the selected set of financial ratios as calculated with data reported according to the traditional Czech accounting standards （CAS） and under the IFRS provisions. Our study discovers that there are important differences resulting from the two reporting formats. Our research comes to a conclusion that translation of Czech statements to IFRS may cause changes in the values of financial indicators without relationship to the real change in the firms＇ value, performance, and stability. Even though the findings were not statistically significant, the indicative results of our measurements disclosed an important fact that the transition to IFRS could cause deterioration of key indicators and thereby could impact on the overall rating of companies. One needs to be cautious with generalization due to the small sample size.
