Determinants and consequences of voluntary switches to Chinese auditors in Hong Kong

Hong Kong market regulators have permitted 12 large Chinese accounting firms to audit the financial statements of Chinese firms that cross list in Hong Kong (i.e., H-share firms) since 2010. This paper examines the characteristics of H-share firms that voluntarily replaced their Hong Kong (HK) auditors with Chinese auditors, and the market reaction to auditor switches following this policy. We find that 38 out of 147 H-share firms voluntarily switched to Chinese auditors during 2011–2013. Switching firms are larger in size and are less likely to use Big4; they also have less need for external financing, a longer cross listing history, and a lower percentage of foreign revenue. We also find that investors negatively react to the auditor switches from HK non-Big4 to China non-Big4, but do not react to the auditor switches from HK Big4 to China Big4. This suggests that investors perceived lower audit quality for China non-Big4.     

Audit committee quality,auditor independence,and internal control weaknesses

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.     

The determinants of auditor switching from the perspective of corporate governance in China

This paper reports the association between firms' internal corporate governance mechanisms and their auditor switch decisions in the Chinese context. We identify two types of auditor switch, namely switching to a larger auditor and switching to a smaller auditor. Three variables are used to proxy for firms' internal corporate governance mechanism, including the ownership concentration (shareholding by the largest owner), the effectiveness of supervisory board (SB), and the duality of chairman of board of directors (CBoD) and CEO. We regressed the internal corporate governance variables over firms' audit switching types during a specific period of 2001-2004 when a bear market continued in China. The empirical results demonstrate that firms with larger controlling owners or in which CBoD and CEO are held by the same person are more likely to switch to a smaller auditor rather than to a larger one. However, the effect of the SB variable does not have a significant impact on auditor switching decisions. In general, the study findings suggest that firms with weak internal corporate governance mechanism tend to switch to smaller or more pliable auditors in order to sustain the opaqueness gains derived from weak corporate governance. On the other hand, with the improvement of corporate government, firms should be more likely to choose large (high-quality) auditors in making auditor switching decisions.     

The impact of corporate governance on auditor choice: Evidence from China

As the largest and fastest growing emerging market, China is becoming more and more important to investors throughout the world. The purpose of this paper is to investigate the determinants of firms’ auditor choice in China in respect of their corporate governance mechanism. Normally firms have to take a trade-off in their auditor choice decisions, i.e., to hire high-quality auditors to signal effective audit monitoring and good corporate governance to lower their capital raising costs, or to select low-quality auditors with less effective audit monitoring in order to reap private benefits derived from weak corporate governance and less-transparent disclosure (the opaqueness gains). We develop a logit regression model to test the impact of firms’ internal corporate governance mechanism on auditor choice decisions made by IPO firms getting listed during a bear market period of 2001–2004 in China. Three variables are used to proxy for firms’ internal corporate governance mechanism, i.e., the ownership concentration, the size of the supervisory board (SB), and the duality of CEO and chairman of board of directors (BoDs). We classify all auditors in China into large auditors (Top 10) and others (non-Top 10), assuming the large auditors can provide higher quality audit services. The empirical results show that firms with larger controlling shareholders, with smaller size of SB, or in which CEO and BoDs chairman are the same person, are less likely to hire a Top 10 (high-quality) auditor. This suggests that when benefits from lowering capital raising costs are trivial, firms with weaker internal corporate governance mechanism are inclined to choose a low-quality auditor so as to capture and sustain their opaqueness gains. On the other hand, with improvement of corporate governance, firms should be more likely to appoint high-quality auditors.     

The Role of Tacit Knowledge in Auditor Expertise and Human Capital Development

Two critical aspects of the model of auditor expertise development in Tan and Libby [1997] are that audit firms do not value tacit knowledge in inexperienced auditors but do value it in experienced auditors. We update the former and extend the latter. Our paper predicts and finds that audit firms now do value tacit knowledge in inexperienced auditors, especially when their supervisors have higher tacit knowledge. Our proxies of value include higher promotability assessments, annual evaluations, and cash bonuses. Our paper also extends Tan and Libby [1997] by positing that enhanced development of expertise and audit firm human capital are two reasons audit firms value tacit knowledge in experienced auditors. As predicted, higher tacit knowledge in experienced auditors is positively associated with higher tacit knowledge acquisition by their inexperienced subordinates and with stronger firm commitment of inexperienced subordinates having higher tacit knowledge.     

Does auditor designation by the regulatory authority improve audit quality? Evidence from Korea

In Korea, the regulatory authority designates external auditors for firms that are deemed to have strong incentives and/or great potential for opportunistic earnings management, and mandates these firms to replace their incumbent auditors with new designated auditors and to retain them for a certain period, typically one to three years. We call this regulatory regime ‘auditor designation’. This paper investigates whether the auditor designation rule in Korea is effective in deterring managers from making income-increasing earnings management. Consistent with our hypothesis, we find that the level of discretionary accruals is significantly lower for firms with designated auditors than firms with a free selection of auditors. We also find that firms with mandatory auditor changes (i.e., auditor designation) report significantly lower discretionary accruals compared to firms with voluntary auditor changes. The above findings are robust to a battery of robustness checks. Overall, our results are consistent with the notion that the auditor designation enhances audit quality and thus the credibility of financial reporting.     

The effect of auditor IT expertise on internal controls

Material weaknesses in internal controls related to information technology (IT) represent unique threats to organizations. Utilizing the external auditor as an example of an externally observable governance mechanism, we investigate if firms with revealed IT internal control deficiencies employ a strategy of disassociation with their current auditor. Our tests show that prior evidence of disassociation strategies hold in both IT and non-IT contexts. Of particular focus to our study, we document a positive association between firms that report IT material weaknesses and subsequent auditor dismissals or switching. We next investigate the potential internal control benefits of switching to auditors with greater expertise in environments that emphasize the importance of IT. We argue that greater audit firm IT expertise promotes improved internal controls for their clients, especially those controls that are dependent on IT. We find that clients that switch to auditors with greater IT expertise, relative to their former auditor, have a greater likelihood of material weakness remediation within one year of reporting control weaknesses. Complementing these findings, we find that audit IT expertise is negatively associated with both non-IT and IT material weaknesses in an ex ante reporting setting. Prior literature takes a longstanding interest in both the incentive for developing auditor expertise and the effects of that expertise. We contribute to this literature stream by providing additional evidence related to a specific type of expertise.     

An Empirical Investigation of the Interface Between Internal and External Auditors

Professional standards place specific responsibilities on auditors for the discovery of material mis-statements in reports of corporate financial performance. Certain factors have been shown to increase the likelihood of fraudulent financial reporting. One warning sign is the potentially pervasive effect of a weak internal control environment consistent with a weak internal audit group. This study investigates the impact of internal audit department quality differences on auditors ‘willingness to place reliance on the work performed by internal auditors. The study also gives consideration to auditors’ recent experiences with material errors and irregularities and examines the influence of two previously untested individual auditor differences on audit judgment decisions: (1) conflict management style and (2) perception of internal/external auditor communication barriers. The results indicate that auditors attend to internal audit department quality differences and that individual auditor differences exhibit significant influence over auditor judgments. Implications for audit practice are considered and directions for future research are suggested.     

Does Ethical Culture in Audit Firms Support Auditor Objectivity?

The suggested cause of constrained auditor objectivity has been centred on auditors' financial incentives and long audit tenure. Recent research has challenged those assumptions and questioned the effectiveness of auditor rotation to counteract short-tenure threats to auditor objectivity. Audit firms and regulators need to adopt methods for enhancing auditor objectivity that are effective in various auditor–client relationships. This study examines whether audit firm ethical culture is positively related to auditor objectivity. Based on the responses of 281 practising auditors, the findings indicate that auditors are more likely to make objective judgments in ethical cultures characterized by the rewarding of ethical behaviour and punishment of unethical behaviour, prevalence of ethical norms, visible ethical leadership, and low emphasis on obedience to authority. In conclusion, evidence indicates that auditors in audit firms with a strong ethical culture are more likely to maintain auditor objectivity than are auditors in less supportive cultures. This suggests that audit firms should promote a strong ethical culture to reduce the risk of constrained auditor judgment.     

Regulatory risk and auditors’ reporting conservatism: Evidence from Chinese comment letters

We study how auditors respond to regulatory risk that arises when their clients receive comment letters from Chinese stock exchanges. Our results show that auditors are more likely to issue modified or conservative—but not excessively conservative—audit opinions to the recipients of comment letters. This reporting conservatism is especially pronounced when the regulatory risk perceived by auditors rises, such as when comment letters contain more questions, when more comment letters are issued, when the auditors must give opinions on specific issues, or when comment letters involve more auditor issues. Comment letters have been issued in China since 2013, but did not have to be disclosed until 2015. We find no significant difference in the impact of comment letters on auditor conservatism between pre- and post-disclosure periods. Further, the size of auditor firms has no significant effect on the impact of comment letters in post-disclosure periods. We interpret our results as supporting the regulation risk hypothesis.     

Internal control reporting differences among public and governmental auditors: The case of city and county Circular A-133 audits

We investigate potential differences in audit reporting outcomes between Circular A-133 audits performed by governmental auditors vs. those performed by certified public accounting (CPA) firms. Specifically, we investigate the association between auditor type and the likelihood of auditor-disclosed internal control concerns. We employ a cross-sectional sample of 13,386 single audit reports of US cities and counties during 2004–2006. In contrast to prior literature, the results indicate that in the post-Sarbanes–Oxley environment, CPA firms appear more likely to issue audit reports that identify internal control concerns than are governmental auditors in the context of Circular A-133 audits. The differences are more pronounced for larger CPA firms.     

The effect of external audits of internal control over financial reporting on financial reporting for clients of Big 4, Second-tier,and small audit firms

The external audit of internal control over financial reporting (ICFR) is a very expensive and contentious aspect of the Sarbanes–Oxley Act (SOX). Larger public firms were first required to file a management report on and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the audit requirement. Whereas most related prior research investigates the combined effect of management and auditor reports on financial reporting, this study examines the distinct effect of auditor reports on reporting quality. For companies audited by small auditors, we find evidence that financial reporting quality improves with an auditor report on ICFR. We find no evidence that auditor ICFR reports improve reporting quality for clients of Big 4 or Second-tier audit firms. Our study adds to the debate on the applicability of SOX Section 404 to smaller firms.     

The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

New Auditors’ Decisions for Released Firms from the Mandatory Auditor Designation Rule: Evidence From South Korea

This study examines the effect of the mandatory designation rule on audit fees charged and audit hours rendered by auditors for firms released from the mandatory auditor designation rule in the Korean audit market. Under the mandatory auditor designation rule, which took effect in 1991, problematic firms are assigned new auditors by the Financial Supervisory Service. Previous studies suggest that this regulation positively affects the quality of audits by promoting auditor independence. Thus, this study hypothesises that firms that have been subjected to mandatory auditor designation improve the quality of their financial reporting, and that auditors hired after the mandatory designation period account for reduced audit risks when determining audit fees and audit hours. This study shows that audit fees and audit hours of firms released from the mandatory auditor designation rule are lower than those of other initial audit engagements. Taken together, this study's findings reinforce the notion that auditors’ perceptions of changes in audit risk yield corresponding changes in the audit fees they charge and audit hours they render.     

Information uncertainty and auditor reputation

This paper explores the relationship between information uncertainty and auditor reputation revealed by the failure of Arthur Andersen (AA). AA’s reputation deteriorated considerably when it announced on January 10, 2002, that it had shredded documents related to its audit of Enron. AA’s demise was sealed on March 14, 2002, with its indictment for obstruction of justice. We find that on these dates the clients of AA and other Big Five auditors that are characterized by higher information uncertainty experience relatively larger share price declines compared to clients with lower information uncertainty. The findings suggest that the market relies more heavily on auditor reputation for higher information uncertainty firms, which implies that the value of an audit is greater when a firm is harder to value. Our results highlight the importance of information uncertainty in financial markets: where there is a shock to auditor reputation, firms with greater information uncertainty suffer the largest losses.     

Audit fee lowballing: Determinants,recovery, and future audit quality

Prior research on the link between lowballing (LB) of audit fees and audit quality is inconclusive. Using more recent data and an innovative design, we define LB engagements as those where the audit fee discount is at least 30 percent. We consider three research questions to understand the possible link between LB and audit quality. First, we investigate whether the two variables that are often associated with auditor independence in the literature—non-audit fees and client importance—are related to LB. Second, we test whether lowballing auditors recoup initial audit fee discounts in the future period. Lastly, we investigate the relation between recovery of audit fees and future audit quality. We find that non-audit fees in the first year of engagement are negatively related to the propensity to LB. LB is significantly positively related to client importance for client firms switching from a non-Big N to another non-Big N auditor while the relation is insignificant for client firms switching from a Big N to another Big N auditor. The results of non-audit fees and client importance indicate that economic dependence does not motivate audit firms to lowball. Further, lowballing auditors tend to recoup their initial fee discounts in subsequent periods via increases in audit fees. Using multiple measures of audit quality, we do not find a significant relation between recovery of audit fees and future audit quality. Overall, contrary to regulators’ concerns, our results suggest that LB does not impair audit quality.     

Experimental evidence of how prior experience as an auditor influences managers’ strategic reporting decisions

We design an experiment to examine the influence of audit experience on subsequent reporting decisions when auditors become managers of audited firms. In contrast to the independence issues that can arise when auditors and their clients are related by prior affiliation, we focus this study on the more common case in which auditors assume subsequent employment with other firms’ clients. In a bi-matrix experimental game that captures key features of the strategic tension between auditors and reporters, we find that reporters who have prior experience as an auditor, particularly the experience of having been a diligent auditor, are more sensitive to large penalties for aggressive reporting than are reporters whose experience is exclusively as a reporter. Our results suggest implications for regulators in predicting the effects of reporting penalties and for firms in considering the effects of CPA experience when hiring for reporting positions.

The Effects of Business Risk on Audit Pricing

This paper examines the pricing of business risk by homogeneous auditors in a two period model. Incumbent auditors learn the client's business risk type during the course of the engagement. They subsequently compete in prices with prospective auditors. In such an environment, we show that equilibrium audit fees do not fully reflect the cost of business risk. Moreover, there exists differential auditor turnover between high and low risk firms; cross-subsidization of the audit fees of high risk firms by low risk firms; and low-balling by auditors.     

The Effect of IPO Risks on Auditors’ Decisions: Auditor Designation Case

This study examines the effect of audit risks in the Korean initial public offering (IPO) market on the designated auditors’ decisions. The Korean External Audit Act requires firms to switch from incumbent to new auditors designated by the Securities and Futures Commission after the firm announces a future IPO. This study shows the effects of audit risks by examining if the quality of reported earnings and audit fees significantly differs between IPO‐eligible and IPO‐ineligible firms. Empirical tests first show that discretionary accruals are significantly lower for IPO‐ineligible firms than for IPO‐eligible firms in both the IPO designation period and the following review period. We interpret this result to mean that designated auditors evaluate the IPO‐ineligible (and eventually failed) firms’ listing possibility as low. Second, audit fees are higher for IPO‐ineligible firms in the auditor designation period. This reflects the fact that designated auditors are exposed to future audit risks associated with firms’ post‐IPO financial market troubles if IPO‐ineligible firms attempt to go public. Our study contributes to IPO‐related research by showing the effects of auditors’ risk evaluation on discretionary accruals and audit fees. This study also contributes to accounting policymaking regarding auditor independence.
