Measuring the Impact of International Financial Reporting Standards on Market Performance of Publicly Traded Companies

Abstract

The decision whether to require publicly traded companies to adopt International Financial Reporting Standards (IFRS) remains in flux. In 2008, the US Securities and Exchange Commission proposed a roadmap leading to complete acceptance of IFRS in the US. With the potential replacement of US GAAP with IFRS in the near future, understanding the impact of IFRS on corporate financial reporting is more important than ever. This study examines two factors which are critical considerations in the decision to accept or not accept IFRS in the US: How different is financial statement information derived under IFRS from information derived under US generally accepted accounting principles (GAAP); and how much incremental information value, if any, is provided by IFRS over US GAAP. The present study extends prior research by examining concurrently both differences and their impact on market performance. Findings of this study support the view that differences on financial statement results between IFRS and US GAAP are not significant, thus, supporting proponents of adoption of IFRS in the US, after which all US publicly traded companies would use IFRS and not US GAAP.
