美國次級房貸風暴自2007年7月爆發以來，除重創金融市場外，亦導致相關會計準則之修訂。本研究以我國金融業為對象，探討：（1）以公平價值認列之金融商品及相關金融資產負債之損益，其財務報導是否具有價值攸關性；（2）金融資產減損損失對投資人之影響是否重大；（3）可能產生減損損失之金融資產其財務報導是否具有價值攸關性；以及（4）財務會計準則第34號公報第二次修訂對投資人之影響為何。 / 本研究之主要發現如下：（1）以公平價值認列之金融商品具有價值攸關性，亦即其對投資人具有參考價值；（2）金融資產減損損失及無活絡市場之債券投資具有價值攸關性，金融資產減損損失增加時，會降低公司之價值，而影響投資人決策；以及（3）第34號公報第二次修訂之內容，對股價具有負向之解釋能力，亦即投資人並不認為金融商品重分類規定之放寬，有助於降低金融風暴對於金融業可能帶來的衝擊。 / Since the U.S. subprime mortgage crisis broke out in July, 2007, it not only inflicted heavy losses to global financial markets, but also caused changes in accounting standards. Using the financial industry in Taiwan as research sample, this study examines: (1) whether financial instruments measured at fair value and their reported gains and losses in the financial statements have value-relevance; (2) the influence of impairment losses of financial assets; (3) whether the financial instruments related to impairment losses of financial assets are value-relevant; and (3) the influence to investors before and after the Statements of Financial Account Standard (SFAS) No. 34 second revised. / This study’s major findings are as follows. The financial instruments measured at fair value are value-relevant and can provide incremental information to investors. Impairment losses on financial assets and non-active market investments also have value-relevance. If a company has more impairment losses on its financial assets, it may negatively affect the firm’s value and change investors’ decisions. As for the second revision of SFAS No. 34, it did not reverse investors’ expectations of the negative effect of the aforementioned financial crisis on the financial industry in Taiwan.

本研究之研究主題有兩大部份。第一部份探討公司特質與其使用衍生性金融商品之關聯性。第二部份探討公司特質與其使用衍生性金融商品程度之關聯性，並檢驗我國財務會計準則第34號及第36號公報實施後，對企業操作衍生性金融商品之影響。 第一部份之實證結果顯示，公司規模愈大、長期負債比率愈高、股利發放率愈高、流動比率愈低、研發費用率愈高以及外銷比率愈高之公司，愈傾向使用衍生性金融商品。上述公司特質為企業使用衍生性金融商品之決定因素。 第二部份之實證結果顯示，公司規模愈大、長期負債比率愈高、股利發放率愈高以及外銷比率愈高的公司，其衍生性金融商品使用程度愈大。此外，第34號及第36號公報實施後，樣本公司使用衍生性金融商品之程度低於公報實施前，故推論此兩號公報之實施，的確影響公司對於衍生性金融商品之操作，使其態度趨於保守。 / This study focuses on the following issues. First, this study examines the relationship between corporate characteristics and its use of derivatives. Second, I further investigate the relationship between corporate characteristics and its degree of use of derivatives. In addition, the impact of SFAS No.34 and No.36 on corporate use of derivatives is also examined. The main conclusions are as follows. On the first issue, the empirical results show that for the firms with greater size, greater long-term liability ratio, greater dividend payout ratio, lower current ratio, greater R&D ratio and greater export ratio, they are more likely to use derivatives. These characteristics are important determinants for corporate use of derivatives. In the second issue, the empirical results indicate that for the firms with greater size, greater long-term liability ratio, greater dividend payout ratio and greater export ratio, their degrees of using derivatives are greater. In addition, the degree of corporate use of derivatives decreases after SFAS No. 34 and No. 36 became applicable. The corporate use of derivatives became more conservative after the application of these two pronouncements.

本研究之目的在探討，上期對本期所做之盈餘預測與本期實際盈餘間誤差所產生之未預期盈餘，對於管理階層在本期預測下期盈餘以及財務分析師針對該預測所作之預測修正，即對於該兩者的攸關性是否會隨著34號公報之實施而提高，也就是說，在34號公報實施之後，未預期盈餘對於管理當局盈餘預測以及分析師預測修正之影響，是否會更加顯著相關。 實證結果顯示，不論34號公報適用前後，管理當局盈餘預測與未預期盈餘之間皆具有攸關性，但在34號公報適用之後，兩者之間的顯著性並未增強；而另一方面，在34號公報適用前後，財務分析師盈餘預測修正與未預期盈餘之間皆具有攸關性，且在34號公報適用之後，兩者之間的顯著性有增強。 / This thesis examines whether the issuance of SFAS No.34 can heighten the association between the unexpected earnings for current period and the management earnings forecast for the next period. This research also examines if the issuance of SFAS No.34 will heighten the relationship between the unexpected earnings for current period and the analysts’ revision of the management earnings forecast for the next period. The unexpected earnings mean the difference between the earnings forecast for current period and the actual earnings in current period This thesis finds that there is a negative association between management earnings forecast and the error of the expected earnings whether SFAS No.34 has been issued or not, but the issuance of SFAS No.34 doesn’t heighten the association between the management earnings forecast and the error of the expected earnings. Besides, the result of the research shows that there is a positive relationship between the analyst’s revision of the management earnings forecast and the error of the expected earnings. Furthermore, the relationship is heightened by the issuance of SFAS No.34.
