本研究探討公司財務報表穩健性之高低對於管理階層認列資產減損動機之影響,由於減損迴轉利益會受前期認列減損損失之影響,因此,一併探討財務報表穩健性高低對於前期減損損失與減損迴轉利益之間關係的影響。另外,過去文獻指出穩健原則會受到公司治理的影響,當公司治理機制愈好,則公司穩健性愈高(García Lara, García Osma and Penalva 2009),因此加入公司治理機制分別檢測公司治理好壞對於財務報表穩健程度與認列資產減損動機,以及財務報表穩健程度對於前期減損損失與認列減損迴轉利益之間關係的影響。 實證結果發現,財務報表穩健性愈高,對於抑制基於洗大澡動機及盈餘平穩化動機,而認列減損損失並沒有顯著之影響,其原因可能為財務報表穩健性會受到公司治理機制之影響。此外,財務報表穩健性愈高可以降低管理者藉由前期認列較多之減損損失而後期多列迴轉利益之操弄。再者,當公司治理較佳,財務報表穩健性愈高對於抑制基於洗大澡動機及盈餘平穩化動機而認列資產減損損失並沒有顯著影響,然而本研究亦發現一個有趣之結果,在公司治理較差之公司,當財務報表穩健性愈高,則會促使管理者有盈餘平穩化的動機,但若財務報表穩健性愈高,反而可以降低管理者藉由前期認列較多之減損損失而後期迴轉較多的減損利益。
This paper explores firms accounting conservatism of financial statements how to influence the managers’ s motivation of recognizing asset impairments. Because of gains on reversal of impairment losses will be affected by previously recognizing impairment losses, it also explores accounting conservatism of financial statements effect on the relationship between previously recognized impairment losses and gains on reversal of impairment loss. Further, García Lara, García Osma and Penalva(2009)find that the stronger corporate governance result in increased conditional conservatism. Therefore, it individually examines corporate governance mechanism impact on the association between accounting conservatism of financial statements and managers’ s motivation of recognizing asset impairments. Empirical results show that the higher level of accounting conservatism of financial statements is not significance effect on inhibiting firms recognized impairment loss based on income smoothing incentive or take a big bath incentive. It is the reason why corporate governance influence accounting conservatism of financial statements. Besides, the higher level of accounting conservatism of financial statements can reduce mangers recognized more gains on reversal of impairment losses by recognizing more impairment losses previously. Furthermore, the stronger the corporate governance mechanism is, the higher level of accounting conservatism of financial statements don’t mitigate manager’s motivation of income smoothing or motivation of take a big bath . However, the weaker the corporate governance is, the higher level of accounting conservatism of financial statements facilitate manger’s income smoothing incentive, but it can reduce mangers recognized more gains on reversal of impairment losses by recognizing more impairment losses previously.
