Outline of Final Research Achievements

The following is a summary of the research findings. First, the study found that the voluntary adoption of IFRS had a significant positive impact on the net income of Japanese voluntary adopters; accounting standards for goodwill, intangible assets, and retirement benefits had a significant impact on net assets and net income; IFRS voluntary adopters had a higher ratio of goodwill to total assets than Japanese standards adopters. Second, using Japanese firms that voluntarily adopted IFRS as a sample, the study found that the adjustment amounts from J-GAAP to IFRS due to four accounting standards (goodwill, revenue recognition, income taxes, and impairment) had positive incremental value relevance. Third, we found that fair value accounting-oriented pension accounting may not be adequate to achieve the objective of reporting to shareholders.

Academic Significance and Societal Importance of the Research Achievements

まず、日本基準とIFRSとのコンバージェンスが進展してきたにもかかわらず、両会計基準に準拠して報告された会計数値の間には顕著な差異が存在していること、その差異は主に両会計基準それぞれの基礎になる考え方の違いに起因していることを明らかにした。次に、両会計基準の個々の会計基準の差異が価値関連性に与える影響を解明することによって、IFRS適用に関する研究蓄積を増やした。最後に、公正価値会計一辺倒の退職給付会計の限界に関する研究成果は、歴史的原価会計と公正価値会計の調和を図る二元観のほうが，後者だけを重視する一元観よりも株主向けの報告目的を果たす可能性があると示唆している。
