摘要 根據金融監督管理委員會要求,我國上市、櫃公司須於2012年財務報表附註揭露我國一般公認會計原則(ROC GAAP)與國際財務報導準則(IFRSs)雙軌並行編製財務報表所產生之差異調整數。因此本研究以台灣上市、櫃公司為研究對象,樣本期間為2012年第一季至第四季,首先探討IFRSs差異調整數價值攸關性,其次進一步探討IFRSs差異調整數是否影響盈餘及權益之相對價值攸關性,最後將企業區分為虧損及獲利,探討上述價值攸關性是否有不同之變化。 實證結果顯示,IFRSs盈餘差異調整數具價值攸關性,且IFRSs盈餘差異調整數可提高權益價值攸關性,但對盈餘價值攸關性並無顯著影響。最後,將企業區分虧損及獲利後,結果顯示,當企業為獲利的情況時,IFRSs盈餘差異調整數價值攸關性大於權益差異調整數價值攸關性,且IFRSs盈餘差異調整數對盈餘價值攸關性之影響大於權益價值攸關性;反之,當企業為虧損的情況時,IFRSs盈餘差異調整數對權益價值攸關性之影響大於盈餘價值攸關性。
Abstract Taiwan listed companies are required to disclose reconciliations from ROC GAAP to IFRSs for their financial reporting in 2012. This provides an opportunity to examine the impact of the IFRSs book-value reconciliations and earnings reconciliations on relative value-relevance of both earnings and book values. Using sample from Taiwan listed companies, empirical results show that the IFRSs earnings reconciliation disclosures in 2012 are relevant to stock price. This research also finds that the larger IFRSs earnings reconciliation, the more value-relevance increase of book value, in contrast, the more value-relevance less of earnings. Furthermore, this study finds that, in profitable firms, the value relevance of IFRSs earnings reconciliation significantly higher than IFRSs book value reconciliation, and the larger IFRSs earnings reconciliation, the more value-relevance increase of earnings. In contrast, the disclosure of earnings reconciliations in loss firms has a greater impact on the value-relevance increase of book value than on the value-relevance of earnings.
