RELEVANCY OF ACCOUNTING INFORMATION UNDER IFRS AT BORSA ISTANBUL (BIST) FOR MANUFACTURING FIRMS

This study aims to measure the impact of IFRS adoption on the relevancy of accounting information at the manufacturing firms listed in Borsa Istanbul. To achieve the objectives of the study, a regression model is applied on a dataset divided into two periods; the first covers the pre adoption period from 1996 to 2004, and the second covers the post adoption period from 2005 to 2013. The applied regression model aims to measure the explanatory power of book values and earnings to explain stock prices. The result of the cross-sectional analysis shows that the relevancy of accounting information increases after the adoption of IFRS. However, when quarterly data is used, the result shows that the relevancy declines after the adoption of IFRS
