This study has two objectives. The fi rst is to investigate the impact of International Financial Reporting Standards (IFRS) adoption on the relevance of earnings for equity valuation. In this regard, the 2005 full convergence to IFRS in Hong Kong provides a natural experimental setting. The opportunity is that the 2005 fi lings of Hong Kong public fi rms require disclosure of information based on the new IFRS as well as on the former local Generally Accepted Accounting Principles (GAAP) [Non-IFRS]. The second objective is to examine whether, and if so how, auditors respond to the different risk exposure arising from the IFRS numbers through their pricing decisions. Our results on the IFRS convergence in Hong Kong suggest an improvement in the value relevance of earnings following convergence. Further, audit fees are more responsive to the new IFRS numbers than to the Non-IFRS numbers, consistent with the interpretation that auditors price their audit work in response to the different risk exposure under the new IFRS numbers.
