這十幾年來台灣地區高科技電子業之所以能夠蓬勃發展，除了研究發展、資本密集等因素外，人力資本可謂居功甚偉，因此，探討台灣上市公司財務報表中，有關人才培訓支出投資抵減的內容揭露，是否與企業價值之間具有攸關性，以及企業當期發生之積極人才培訓支出(以其投資抵減金額衡量）是否可以有效提高企業之財務績效表現及降低企業員工之離職率，本研究利用2002-2005年台灣上市公司之財務資料、遞延所得稅與所得稅抵減揭露資訊以及設算之員工離職率，採用Pearson相關分析及OLS複迴歸分析進行探討。 研究結果顯示，人才培訓支出投資抵減（不論是企業當期發生金額或是期末餘額）與企業價值間不具有攸關性。而在以毛利率衡量企業財務績效時，企業當期發生之人才培訓投資抵減，會對企業當期之財務績效有顯著的正面影響，亦對企業次期之財務績效有顯著的正面影響，顯示企業對於員工的教育訓練可以增加企業當期與次期之毛利率；但在以修正後資產報酬率、修正後權益報酬率及營業利益率分別衡量企業財務績效時，則對企業當期與次期之財務績效，皆未有顯著之正面影響。此外，企業當期發生之人才培訓支出投資抵減，與企業當期與次期之員工離職率顯著負相關，顯示企業當年對員工的教育訓練，可以提高員工對於企業的歸屬感及工作滿意度，而降低當年與後續年度企業員工之離職率。 關鍵詞：人才培訓支出投資抵減、遞延所得稅、價值攸關性、教育訓練、企業財務績效、離職率。

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.

退休金的會計處理原本即具複雜性，加上最近退休金制度的變革，形成退休金會計獨特且豐富的情境背景，提供了許多的研究機會。本論文包含三個與退休金會計相關之議題；其中第一個議題是「勞工退休金新制之股價效應」；第二個議題是「退休金精算假設選用之誘因」；第三個議題是「退休金精算假設選用之價值攸關性」。三個議題均以效率市場假說為基礎，針對勞工退休金新制之實施與退休金精算假設之選用，分別深入探討其與股價之關聯性。 首先，本論文第一個議題探討勞退新制之股價效應。事件日股票報酬與公司特質的關聯分析，雖然部分的實證結果不顯著，然而部分的證據顯示，勞退新制公布實施時，公司股票報酬與退休金提撥不足程度、員工平均服務年資、退休金提撥率、退休金成率等公司特質具有關聯性，隱含資本市場在某種程度上，似乎可以依據勞退新制對公司不同之衝擊程度，反映於公司股票報酬。 其次，本論文第二個議題探討退休金精算假設選用之誘因。實證的結果顯示，我國上市上櫃公司精算假設選用的橫斷面差異，可能源於債務契約、提撥不足之成本以及損益平穩化等誘因。最後，本論文第三個議題探討退休金精算假設選用之價值攸關性。實證結果顯示，退休金精算假設選用具價值攸關性，投資人對公司選用精算假設保守程度有所評價，對於裁量性 (隱藏的) 預計給付義務亦有所反映，似乎適當地根據精算假設選用對於預計給付義務之影響幅度來調整對公司之評價，隱含資本市場並未功能性固著於報導的退休金義務。 / There are three essays in this dissertation. The first essay examines the impact on equity prices of the Promulgation of Labor Pension Act. Evidence reported in the paper shows that negative abnormal returns are most pronounced for firms with large underfunded level of pension plan, firms with little average years of employment, firms with low contribution ratio, and firms with low pension cost ratio. The second essay explains the cross-sectional variation in firms’ selected actuarial assumptions (rate of increase in compensation and discount rate) used to measure the projected benefit obligation (PBO). Evidence shows that firms with relatively larger debt ratio, larger underfunded level of pension plan, and larger decline in earnings tend to select more aggressive (obligation-reducing) estimation parameters. The last essay studies the association between actuarial assumptions and firm value. The results indicate that firm value is lower, conditional on the reported PBO, for firms that use higher discount rates and lower rate of increase in compensation. This is consistent with investors seeing through managers’ opportunistic choices of obligation reducing assumptions. The evidence suggests that the stock market does not fixate on reported PBO numbers, but properly appreciates the value relevance of the discretionary component of the PBO.

依據財務會計理論，附註揭露為整體財務報表的一部份，其目的在提供投資人進行企業評價時所需之攸關資訊。兩稅合一制度實施後，不僅使稅賦型態轉變，會計原則中也新增附註揭露股東可扣抵稅額之規定，因此提供了驗證資本市場與財務報表揭露的機會，本研究即針對股東可扣抵稅揭露是否具有價值攸關性進行測試。 本研究以87年為樣本年度，分析資料完整的317家上市公司，透過Ohlson模型來檢測股東可扣抵稅額之價值攸關性，並處理Ohlson模型中兩個重要的information dynamics，以異常盈餘（xa ）及其他資訊（v）做為模型中的自變數，將財務分析師之財務預測（analysts’forecasts）做為Ohlson模型中其他資訊（other information）之代理變數，以捕捉Ohlson模型中其他資訊對股價的影響。最後，考慮產業及公司規模兩項因素，觀察紡織業與電子業對股東可扣抵稅額揭露之反應以及公司規模對於價值攸關性研究的影響。 實驗結果顯示，無論以現金基礎或應計基礎衡量股東可扣抵稅額，其揭露均具價值攸關性，投資人的確使用財務報表附註揭露中有關股東可扣抵稅額之資訊於企業評價上。其次，異常盈餘與其他資訊皆能捕捉股價之變動。最後，在紡織業與電子業中雖未觀察到股東可扣抵稅額之揭露具有攸關性，但公司規模的因素則無論在全體樣本或各別產業中皆具影響力。 / According to modern accouning theory, footnote disclosures are an intergrated part of the overall financial statements. The purpose of footnote disclosures is to provide value-relevant information in assisting investors’ valuation process. After Taiwan’s 1998 Tax Reform, which intergrates the individual and corporate taxes, the current GAAP requires a footnote disclosure of imputation credits (IC). This provides a good chance to test how Taiwan’s stock market reacts to such disclosuer. The main purpose of this study is to examine the value relevance of IC disclosure to investors’ equity valuation. This study uses Ohlson’s (1995) model to analyze 317 firms listed on Taiwan’s Stock Exchang (TSE) during 1998. To estimate the abcdrmal earings and other information (captured by analysts’ forcasts), this study adopts Dechow, Hutton, and Sloan’s(1999) methodology. We also investigate the effects of industry and firm size on the value relevance of IC disclosure. The empirical results reveal three findings. First, there is a positive association between IC and stock price in TSE. Therefore, the IC disclosure is value relevant to investors’ equity valuation. Second, abcdmal earnings and other information can both explain stock price behavior. Finally, when we focus our sample on the textile and high-tech industries, no significant association between IC disclosure and stock price can be found. When we further consider firm size, however, the value relevance of IC disclosure becomes significant. In other word, the value relevance of IC disclosure may be affected by firm size.
