Implications of the mandatory transition from national GAAP to IFRS — Empirical evidence from Germany

This paper analyses the differences between German GAAP and IFRS by quantifying the effects of the first-time adoption of IFRS of German companies in their reporting practices. Due to the IAS Regulation EC No.1606/2002, all publicly traded European companies (including those in Germany) are required to prepare their consolidated financial statements in accordance with IFRS for accounting periods beginning on or after January 1, 2005. This paper measures the effect of the transition from German GAAP to IFRS by using indices of comparability that were developed by Gray (1980). Therefore, the impact on equity and net income is quantified by examining the reconciliations of 103 German companies which had to adopt IFRS for their consolidated financial statements in 2005. On average a significant increase in stockholders' equity and in net income could be observed. The increase in stockholders' equity is primarily due to the adoption of IAS 11, IAS 16, IAS 37, IAS 38 and IFRS 3. Concerning net income, the increase especially results from the adoption of IFRS 3.
