会计师事务所合并与审计收费

以中国2005年以来发生的14起会计师事务所合并案为例,通过大样本的经验研究方法探讨了会计师事务所的合并对审计收费的影响。研究发现,总体来看,会计师事务所合并后审计收费有显著提高;但分组研究发现,只在小客户市场上,会计师事务所合并后审计收费有了显著的提高。进一步的研究发现,在大客户市场上,之所以事务所合并对审计收费的影响无显著的影响,是因为会计师事务所在合并后尽管议价能力有了较大的提升,但同时规模效率也得到了充分的发挥。     

Public Disclosure of Audit Fees and Bargaining Power between the Client and Auditor: Evidence from China

Before the public disclosure of audit fees was mandated, it was unlikely for an audit client to have accurate information about how much other companies were charged by their auditors. Public fee disclosure decreases the cost of auditees' access to audit fee information for the auditor's portfolio of clients and is thus likely to increase the relative bargaining power of auditees over auditors when they negotiate audit fees. Using both proprietary and public audit fee data before and after public fee disclosure was mandated in China, we provide evidence consistent with the preceding conjecture. We find that public fee disclosure reinforces the magnitude of audit fee decreases for overcharged clients and weakens auditors' ability to raise audit fees for undercharged clients. These findings suggest the existence of unintended consequences of public fee disclosure regulation, the original rationale of which was a concern about audit pricing practices that could undermine auditor independence.     

Note on audit fee premiums to client size and industry specialization

This research note examines the impact of client size on the estimation of audit fee premiums in the Australian market for audit services. Previous research suggests that higher audit fees are expected for both larger clients and for industry specialization. We find that in the Australian market for audit services, the fee premium attributed to industry specialist audit firms is concentrated in the audit fees paid by the largest clients in each industry. One reason for higher fees paid by larger clients is the demand for additional audit services. We find higher fees for companies cross‐listed on US exchanges. We also find that fee premiums to auditors that are city‐industry leaders are strongly related to client size.     

Market competitiveness and Big 5 pricing: Evidence from China's binary market

Big 5 auditors enjoy a worldwide audit fee premium that is believed to be attributable primarily to their reputation for providing high-quality services to clients. This study finds that the fee premium is also attributable to a lack of competition in the market. Taking advantage of the binary structure of the audit market in China, we compare the pricing practices of the Big 5 in the competitive statutory market and the less competitive supplementary market. Although the Big 5 have a reputation for high-quality audits in both markets, the degree of competition in the two markets is very different. Using audit fee data from the period 2000 to 2003, we find that the Big 5 earn a significant fee premium in the less competitive supplementary market, but not in the competitive statutory market. Although our results do not completely rule out reputation as an explanation, they are consistent with the notion that the audit fee premium that is earned by the Big 5 is more likely to be attributable to their dominant market position than to their reputation in the emerging Chinese markets, in which the usual audit-quality benefits for investors and managers are either absent or minimal.     

“Surprise” material weakness disclosures: Effects on audit fees and audit report lags

Prior research shows that many of the companies that disclose material weaknesses in internal control (MWs) do not disclose such weaknesses in earlier quarterly 10-Q filings for the same year—i.e., the year-end MW disclosures are “surprise” disclosures. I first show, using data from 2009 to 2019, that such surprise MWs continue to be the majority of MW disclosures as late as 2019. I find that accelerated filer companies with surprise MWs pay lower fees compared to companies with no-surprise MWs; however, this finding does not hold for non-accelerated filers. I also find that there are no significant differences in the audit report lag of surprise and no-surprise MW disclosers. Thus, the lower audit fee paid by surprise MW disclosure companies may offer a possible explanation for the widespread prevalence of surprise MW disclosures. The results also highlight the importance of the external auditor in public disclosures of MWs. The findings have public policy relevance given the ongoing efforts to expand the set of companies that would be exempt from the auditor attestation of internal controls.     

Financial reporting consequences of natural disasters: Evidence from the impact of resource constraints at audit offices on non-affected clients

Disaster-affected clients demand significant additional effort from their audit office, and hence strain the audit office’s resources available to other non-disaster-affected clients. We consider audit offices with disaster-affected clients to be strained offices and find that, compared with clients audited by non-strained audit offices, non-disaster-affected clients audited by strained audit offices are more likely to have their financial statements restated. This result suggests the financial reporting quality of companies not directly exposed to disasters could also be negatively affected by the disasters, due to their auditors’ strained-resource issue. We further find such a negative effect is more pronounced when the degree of resource constraints is greater and when the audit office lacks client experience or industry expertise. We offer novel evidence of financial reporting consequences of natural disasters, focusing on the externality of disasters on companies not directly affected by disasters. The findings have important implications for regulators in making disaster-related policies, for auditors in managing their client portfolios, and for companies in making auditor choice decisions.     

Do Control Effectiveness Disclosures Require SOX 404(b) Internal Control Audits? A Natural Experiment with Small U.S. Public Companies

We use incremental and joint implementation of multiple SOX‐based control effectiveness disclosure and audit mandates to assess relative performance of alternatives for small U.S. public companies. Using data from several low‐ and high‐effort management disclosure and audit regimes implemented from 2003 to 2008, we find substantial and statistically significant increases in material weakness disclosure rates for small firms undergoing initial SOX 404(b) internal control audits, but find quantitatively and statistically similar increases for initial management reports of small firms exempt from such audits. As to audit cost, fees more than double for initial 404(b) audits in 2004 and remain high, while 404(b)‐exempt firms’ fees grow about 10% annually. Our results support the view that, for small firms, management internal control reports and traditional financial audits may be a cost effective disclosure alternative to full application of SOX 404(b). Also, our results suggest that, even without management reports on internal control, analysis of the cause of known accounting mistakes may yield substantial material weakness disclosures.     

The 15-day debate and the value of early release of information: Evidence from 10-K filings

We analyze the impact of enforcing a 60-day 10-K deadline on large accelerator filers (LAFs) relative to enforcing a 75-day deadline on accelerator filers (AFs) from 2006 to 2015. Using a regression discontinuity design, we find that LAFs are more likely to issue restatements after the 2006 SEC filing acceleration (“regulation”) has been introduced. The regulation causes LAFs to have lower information asymmetry, which is consistent with our finding that LAFs’ Internet search traffic for filings is lower. Overall, the market does not react stronger toward LAFs’ 10-K filings even though their 10-K filings are more timely. An unintended consequence of the regulation is an increase in filings by other firms during LAFs’ 10-K filing dates, which reduces investors overall attention toward these filings.     

Local Gambling Attitudes and Audit Quality: Evidence from Audit Adjustments

This study examines the influence of local gambling attitudes on audit quality. As a preference for gambling correlates to a greater tendency to take risks, we hypothesize that auditors make a greater magnitude of audit adjustments for clients headquartered in gambling-prone areas to reduce heightened audit risk. Consistent with our hypothesis, the empirical results show a positive relation between local gambling attitudes and the magnitude of audit adjustments. Further analyses show that this association is more pronounced when the regulatory cost is higher, and when the board chair or CEO comes from a gambling-prone area. We also find evidence that gambling culture results in greater magnitudes of both upward and downward audit adjustments, audit firms appoint more experienced audit partners to gambling-prone clients, and there is a fee premium for gambling-prone clients.     

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement.     

Does size matter? The influence of large clients on office-level auditor reporting decisions

Large clients create an economic dependence that may cause auditors to compromise their independence and report favorably to retain valuable clients. Economic dependence is measured as a client's size relative to the size of the office that contracts for the audit and issues the audit report. We find no evidence economic dependence causes Big Five auditors to report more favorably for larger clients in their offices. However, larger clients also pose greater litigation risk, and we do find that Big 5 auditors report more conservatively for larger clients, suggesting that reputation protection dominates auditor behavior.     

Further evidence on mandatory partner rotation and audit pricing: a supply‐side perspective

This study examines effects of mandatory partner rotation (MPR) on audit fees of Australian‐listed companies. Using a fee changes approach, evidence of fee increases in year of the MPR driven by smaller offices of non‐Big 4 auditors is found, consistent with supply‐side resource constraint arguments. Broadly consistent findings are observed using a fee levels approach. Appointment of inexperienced partners to MPR engagements has no discernible effect on fees. Additional analysis of audit reporting lag indicates fee increases reflect additional audit effort as opposed to a pricing strategy. Overall, the evidence supports recent moves by policy‐makers to soften MPR requirements.     

Do supply shocks in the audit partner labor market affect auditor choice? Evidence from a quasi-natural experiment

We examine whether supply shocks in the audit partner labor market induce clients to switch audit partners. We argue that audit partners in their early careers (i.e., junior partners) charge low audit fees to attract clients, which induces client firms to switch from senior partners to junior partners when there are more junior partners available. Utilizing the Big4 localization policy, we find that Big4 clients are more likely to replace senior auditors with junior auditors to cut costs after the policy. Furthermore, the results are mainly driven by clients who are charged high fees. Our empirical evidence enriches the understanding of auditor choice determinants and informs the ongoing debates surrounding new regulations for Big4 firms in China.     

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 association between audit committees,compensation incentives,and corporate audit fees

This study uses audit fee data from the 2001–2003 reporting periods to examine the relationship between measures of audit committee effectiveness and compensation incentives with corporate audit fees. Our results suggest that audit committee size, committee member expertise, and committee member independence are positively associated to audit fee levels, consistent with the notion that audit committees serve as a complement to external auditors in monitoring management. In contrast, CEO long-term pay and insider ownership are inversely related to audit fee levels, substituting for external audit effort in motivating management. Notwithstanding results on the full sample of firm-years, we uncover significant differences in the determinants of audit fees between the years examined. An important implication of these results is that explaining the intra-firm variation in audit fees over time is clearly necessary in order to understand the antecedents and consequences of audit fees.

Employee quality and audit fee: evidence from China

This study investigates the association between employee quality and audit fee. Using data for firm-level employee quality (as proxied by employee education) from Chinese listed firms from 2011 to 2018, we find that firms operated by high-quality employees enjoy lower audit charges. The association between employee quality and audit fee is more pronounced in firms with a culture of high integrity. Our 2SLS estimation helps us establish a causal link between employee quality and audit fee. The final validity tests suggest that high-quality employees contribute to lower audit fee by reducing audit risk and audit effort.     

Is the audit services market competitive following Arthur Andersen's collapse?

This study investigates whether audit markets remain competitive in the wake of Arthur Andersen's demise and merger with Ernst & Young to create the Big Four. We conduct the study estimating audit fee models using Australian audit market data from both 2000 and 2003 to determine whether there is any evidence of cartel pricing either before, or subsequent to, the merger. In both years, we find evidence of a Big N price premium when estimating an audit fee model across all clients, and when we estimate the model separately across large and small client market segments. This evidence is consistent with product differentiation by Big N auditors and competitive markets.     

会计师事务所的属性重要性与审计收费——基于中国会计师事务所综合评价前百家信息的证据

审计收费是对事务所的审计师团队努力的回报,而审计师团队有多种不同重要程度的属性,因此有必要把会计事务所作为一个拥有多个属性重要性的系统,具体考察其对于审计收费的影响。本文根据中国注册会计师协会年度会计师事务所综合评价前百家信息,具体考察了会计事务所的属性重要性对审计收费的影响。研究表明,事务所中的CPA的教育结构、CPA的经验(年龄)结构和事务所综合规模对审计收费具有显著正向影响。事务所其他属性与审计收费未发现存在显著相关性。     

Determinants of auditor changes for non-accelerated filers

Significant accounting scandals and the imminent collapse of Arthur Andersen in 2001 precipitated a period of heightened regulatory response, most notably the enactment of the Sarbanes–Oxley Act of 2002. In the years that followed, the Securities and Exchange Commission created a separate class of non-accelerated filers (companies with public float of up to $75 million) and provided these companies with significant regulatory relief from certain financial reporting disclosure and auditing requirements, including the extension of scaled disclosure to these companies in 2007. Over the period of 2001 through 2007, as non-accelerated clients anticipated and responded to their different and evolving regulatory regime, audit firms were adjusting to the increased concentration in their market, a new monitoring structure, and significant changes to the scope of their work. We examine whether auditor–client misalignment is a significant determinant of auditor change during this period, particularly for non-accelerated filers, as large auditors sought to rebalance their client portfolios. We find evidence that auditor–client misalignment increases the likelihood of auditor change (resignation and dismissal) for non-accelerated, but not accelerated, filers. We also find that auditor–client misalignment increases the likelihood of downward changes to third-tier auditors for non-accelerated, but not accelerated, filers.     

Does International Accounting Network Membership Affect Audit Fees and Audit Quality? Evidence From China

Regulators suggest that small audit firms join international accounting networks to reduce their resource constraints in serving large clients and providing high-quality service. Bills, Cunningham, and Myers (2016) investigate the issue in the United States and find that both audit fees and quality are higher for members of international accounting networks (i.e., member audit firms). We investigate the effects of network membership on audit fees and quality in China, a relatively weaker institutional environment than the United States. Using data of Chinese listed companies audited by non-Big N audit firms from 2001 to 2010, we find that member audit firms charge 3.9% higher fees than nonmember audit firms, much lower than the 30% fee premiums charged by U.S. member audit firms. We do not find consistent evidence that audit quality is higher for member audit firms. Overall, our results demonstrate that China's weak institutional environment may overwhelm the quality control brought by international accounting networks and that it may weaken or even offset the benefits of audit firms' participation in these networks, resulting in smaller or even no effects of membership on audit fees and quality.
