审计师变更、前任审计师任期和会计信息可比性
|
摘要
提高会计信息可比性是制定会计准则的主要目标之一。采用2005—2014年我国沪深A股上市公司为研究样本,考察审计师变更对会计信息可比性的影响,以及前任审计师任期在其中所扮演的角色。经验证据表明:整体而言,发生审计师变更的公司其会计信息可比性要弱于未变更审计师的公司;考虑审计师与客户之间的密切程度后发现,前任审计师任期越长,审计师变更与会计信息可比性的负向关系越为明显;进一步地,不同变更方向对可比性的影响存在差异,升级变更对会计信息可比性的削弱程度不明显;同时,公司在审计师变更后呈现出"可比性回转效应",即随着继任审计师任期的增加,可比性有逐渐恢复的迹象且其与未变更审计师的公司的差异亦逐渐缩小。
Based on the samples of listed companies during 2005-2014 on Chinese A- share market,we examine the effects of auditor switching on accounting information companies and the role of predecessor auditors' tenure among them.The evidence shows that as a whole,accounting information comparability of companies who have switched their auditors is lower than that of those who haven't.After taking the closeness of auditors and clients into consideration,we find that the longer the predecessor auditors tenure is,the more significant the negative relationship between auditor switching and accounting information comparability is.In addition,there are differences in the impact of different switching direction on information comparability-- the degree of lower accounting information comparability is not obvious in auditor upgrade.Meanwhile,companies present "regression effect on compatibility" after auditor switching,namely,the accounting information comparability has recovered after auditor switching,and the difference between the companies with auditor switched and others has narrowed

①Francis等(2014)基于美国资本市场的数据发现国际四大会计事务所会计信息可比性强于非四大事务所。
①这里需要说明的是Barth(2013)认为一致性并不代表可比性,但是一致性有助于实现可比性,所以一致性应该是可比性的一个重要影响因素。
②之所以考虑前任审计师任期是因为Barth(2013)认为一致性并不代表可比性,但是一致性有助于实现可比性,而审计师任期越长,这种一致性越持久。另外,从会计信息可比性的计算过程来看,某一个时点的会计信息可比性需要考虑前16个季度的数据,那么继任审计师审计的时点的公司可比性也很可能会受到前任审计师审计行为的影响。
①Francis等(2014)认为审计师形成审计风格需要一定量的时间。
②需要说明的是模型(2)是在审计师变更样本中进行回归。
①在我们的研究样本中没有找到四大所变更到非四大所的变更样本。
