How different GAAPS affect performance of valuation models: Evidence from Asia-based companies

Use of accounting information to assess a firm's value is a very important subject for financial analysts, investors, lenders, policy-makers, and other market participants. Given the current worldwide movement toward adoption of IFRS, understanding how it compares to other GAAPs and affects valuation models is an important matter. This study compares the relative performance of three valuation models based on a sample of all relevant American Depositary Shares (ADRs) from selected Asian countries and a matched sample of US counterparts, using accounting variables reported under International Financial Reporting Standards (IFRS), US generally accepted accounting principles (GAAP), and non-IFRS/US GAAP. Results indicate that there are substantial differences between the three models' explanatory power and that the dominant (most explanatory) valuation model will vary depending on which GAAP (IFRS, US GAAP, and non-IFRS/US GAAP) is used.
