Abstract: Basu (1997) 提出盈餘穩健性會反應在對好消息及壞消息的認列程度不同,即「資訊認列的不對稱」,並據此理論設計一套公式,以檢驗公司盈餘穩健性的程度。此後,許多學術研究即利用Basu的公式及衡量方法,作為比較當公司在具有某種特質、或處於特定期間、國家時,是否較其他公司有較高(低)程度盈餘穩健性的衡量基準,並依此法則對其研究的特質與盈餘穩健性的關聯性做出結論。
然而,Lin and Liu (2011) 主張在比較不同公司間盈餘穩健性高低時,應將造成資訊認列的不對稱的組成因子(即盈餘對好消息及壞消息的反應)均納入考量;另外他們發現,盈餘反應與消息的關聯性,隨著消息程度的增加而呈現非線性的情形;此外他們也發現,盈餘反應消息亦存在著遞延認列的情形,亦即當期盈餘不會馬上反應消息的全部本質,而會遞延至消息發生後數期才逐漸反應完畢。
本論文在與風險因子之公司特質變數中選擇會計師訴訟風險、公司訴訟風險、公司年齡、及高科技產業為測試標的,而在法規管制因子上選擇沙賓法案(比較施行前後)為測試標的,分別以Lin and Liu (2011) 提出的新衡量方法,重新檢視過去文獻使用Basu (1997)提出衡量條件式盈餘穩健性程度的模型及衡量方法,對條件式盈餘穩健性及公司特質間關聯性所下的結論。實證結果顯示,具有本論文探討特質的公司,其盈餘穩健程度會隨著對消息的種類、程度不同而有不同的結果;以多期盈餘反應模型重新檢驗,亦會得到與過去文獻不同的結論。因此,過去文獻依據Basu衡量方法作出穩健程度與公司特質間關聯性的結論,有應以非線性模型及多期模型重新探討的必要性。
This paper re-examines the effects of firm characteristics on the extent of conservatism under nonlinear and multi-period earnings responses model. Previous studies use Basu’s (1997) measure of conservatism to examine whether firms with a certain characteristic would exhibit higher extents of conservatism than others, yet Lin and Liu (2011) suggest that the attributes of nonlinear and lagged earnings responses should also be considered. I choose several firm characteristics to re-examine the conclusions in prior studies in this paper. For the risk factors, I choose auditor’s litigation risk, firm’s litigation risk, firm age, and membership in high-tech industries; for the regulation factors, I examine whether the passage of SOX would result in firms’ higher exhibition of conservatism. My empirical results indicate that firms would exhibit different extents of conservatism when considering the different absolute magnitudes of news or lagged earnings responses, and suggest that the conclusion in prior literature may need to be reconsidered.
