我國財務會計準則公報第三十五號「資產減損之會計處理」規定，若有證據顯示相關資產可能發生減損，公司應進行減損測試，並據以認列資產減損損失。若已認列之資產減損已不存在或可能減少時，則可將該損失迴轉，但商譽之減損一經認列，即不得迴轉。本研究之目的在於探討商譽減損會計處理之改變，對於企業併購會計方法之選擇及財務報表會計資訊價值攸關性所造成的影響。 本研究之主要發現如下：（1）第三十五號公報發佈後，被併購公司的潛在商譽愈大，主併公司愈傾向採用權益結合法，以避免認列商譽；（2）企業依照該公報編製財務報表時，資產減損可能淪為其盈餘管理之工具，而導致盈餘對股價之解釋能力降低；以及（3）由於商譽減損損失不能迴轉，投資者認為企業較不會透過該類損失之認列，以進行盈餘管理。 / SFAS No. 35: Accounting for Impairment of Assets, requires that an enterprise should evaluate whether or not there are indications that an asset may be impaired on the balance sheet date. If such an indication exists, an impairment test should be performed to determine and recognize the loss. When there is evidence that an impairment loss recognized in prior years may no longer exist or has been reduced, it may be reversed; however, reversal of impairment loss on goodwill is prohibited. The purpose of this study is to investigate how the change on accounting for goodwill impairment affects the accounting for business consolidations and the value relevance of financial statements. Our major empirical results are as follows. (1) For the business consolidation occurred after the issuance of SFAS No. 35, the larger the potential goodwill of the acquired firm, the more likely the acquiring firm would adopt the Pooling method to avoid recognizing goodwill. (2) With the adoption of SFAS No. 35, since firms may utilize the Statement as an earnings management device, the value relevance of a firm’s earnings is decreased. (3) From the investors’ viewpoint, an impairment loss on goodwill is less likely to have earnings management effect because such a loss cannot be reversed.

為了使公司帳面價值符合穩健原則，我國財務會計準則委員會於民國九十三年七月一日公布財務會計準則公報第三十五號 -- 「資產減損之會計處理」。此公報規定當資產之帳面價值高於可回收金額，對於超過的部分即須認列減損損失。本文之目的即在於藉由探討資產減損認列之決定因素，係經濟因素或報導誘因，以瞭解第三十五號公報之實施是否真能達到當初制定之目的，而使公司財報更為透明，更能反映公司的經營績效與價值，而非淪為管理階層盈餘管理之工具。此外，本文亦探討公司資產減損之認列與其股價之關係，以瞭解投資人對資產減損資訊之反應，以及第三十五號公報對市場之影響。 本研究之主要發現如下：（1）國內上市公司認列資產減損之決定因素主要係經濟因素，但亦有藉以平穩其盈餘之現象；以及（2）整體而言，資產減損對股價不具有顯著之影響力，顯示市場對於資產減損並無顯著之反應。但市場對於未提前適用之公司所認列之資產減損，則有顯著之負向反應。 / In July 2004, Financial Accounting Standards Board in Taiwan issued SFAS No. 35: Accounting for Impairment of Assets, to enhance the conservatism in corporate financial statements. SFAS No. 35 requires that when an asset’s book value is lower than its recoverable amount, a company should recognize the difference as an impairment loss. The purpose of this study is to investigate the determinants (economic factors and reporting incentives) of reported impairment losses to evaluate whether SFAS No. 35 achieves its purpose. In addition, this study examines the relationship between reported impairment losses and stock prices to determine the impact of SFAS No. 35 on the capital market investors. Our empirical results show that economic factors are the main determinants of reported impairment losses of the listed firms in Taiwan. There is also a high association between reported impairment losses and corporate “income smoothing” behavior. Overall, reported impairment losses do not have significant impact on stock prices. However, after excluding the early adopting firms, the capital market reacts negatively to reported impairment losses.
