Audit partner rotation and negative information hoarding: evidence from China

We analyse the impact of mandatory audit partner rotation (MAPR) on negative information hoarding about audit clients using a sample of Chinese firms. Our findings suggest that the outgoing audit partners hoard negative information in pre-MAPR, as revealed by a decrease in crash risk, while the incoming audit partners disclose negative information in post-MAPR. Additional analysis suggests that the results are more pronounced among reviewing partners than engaging partners. We also find that when the outgoing audit partner has strong professional abilities or weak personal network with the client or incoming partner, there is less negative information hoarding around MAPR.     

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.     

Audit market concentration,audit fees,and audit quality: A cross-country analysis of complex audit clients

Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market is segmented and that concentration in the Big 4 segment of the market leads to higher audit pricing. Accordingly, our analyses use international data and focus on concentration within the Big 4 group of firms across countries. We find that audit fees are increasing in our concentration measure for clients where the barriers to entry by competing auditors are higher, as proxied by client size, international operations, and IFRS use. Finally, we find evidence that audit quality is decreasing in Big 4 market concentration for these types of engagements. This indicates a wealth transfer from shareholders to audit firms when auditor concentration is high because these complex clients are charged more, but receive audits that are of lower quality.     

The Effect of Previous Working Relationship between Rotating Partners on Mandatory Audit Partner Rotation

This study adds to the literature on mandatory rotation of audit partners in Chinese companies by examining the effect of the pre-rotation relationships between incoming and outgoing partners. We consider the rotating partners to have prior working relationship if they were cosigners of audit reports before the rotation. We find two different outcomes of having prior working relationship: (a) increasing the likelihood that outgoing partners rotate back after the cooling off period, and (b) lower audit quality improvement after rotation. These findings bring into question the extent to which rotating partners with prior working relationships are truly independent.     

The effects of audit firm rotation on perceived auditor independence and audit quality

Our study explores loan officers’ perceptions of auditors’ independence and audit quality under three experimental audit firm rotation scenarios. We use a case experiment with a between-subjects design to determine whether rotation of the audit firm impacts financial statement users’ perceptions of auditor’s independence and quality. Findings based on 212 useable responses indicate that loan officers do perceive an increase in independence when the company follows an audit firm rotation policy. However, the length of auditor tenure within rotation fails to significantly change loan officers’ perceptions of independence. Findings also indicate that neither the presence of a rotation policy nor the length of the auditor tenure within rotation significantly influences the loan officers’ perceptions of audit quality.     

Auditor specialization, perceived audit quality, and audit fees in the local government audit market

Prior governmental research implies a positive relation between auditor specialization and audit quality, but the effect of specialization on audit fees is mixed. However, no single governmental study investigates the effect of auditor specialization on both audit quality and audit fees. Also, prior studies focus on either large- or small audit firms and often employ indirect proxies for audit quality. We study the effects of auditor specialization on perceived audit quality and audit fees. Our data represent both Big 5 and smaller audit firms and include three market-based measures of specialization. We survey 241 Florida local government finance directors and find that specialization is positively associated with perceived audit quality but not with audit fees. We also find that Big 5 auditors, often used as a proxy for higher audit quality in prior research, are not uniformly associated with increased perceived audit quality but consistently charge higher audit fees. Our results confirm a relation between measures of audit firm specialization and audit quality and raise questions regarding audit firm size and audit quality in the municipal sector. Our findings suggest that engaging specialized auditors may be good policy for many local governments.     

The impact of PCAOB international registration on audit quality and audit fees: Evidence from China

Despite the importance of registration with the PCAOB, there is surprisingly little academic research on the registration process and its impact on audit outcomes (Abernathy et al., 2013). The PCAOB allows registration of audit firms from non-US countries. However, China and a few other countries do not allow the PCAOB to conduct inspections of audit firms. We take advantage of this setting to investigate whether PCAOB-registered audit firms improve audit quality in the absence of inspections and whether they charge an audit fee premium. Our findings indicate that audit quality increases following PCAOB registration and that clients pay higher audit fees for audits by PCAOB-registered firms.     

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.     

The impact of audit committee expertise on audit quality: Evidence from UK audit fees

Governance regulators currently place great emphasis on ensuring the presence of financial expertise on audit committees (Sarbanes-Oxley, 2002; UK Corporate Governance Code 2010–2016). Underlying this is a belief that greater expertise enhances the effectiveness of audit committees and, by extension, the quality of the external audit. This study investigates the impact of audit committee expertise on one measure of audit quality - audit fees paid by FTSE350 companies. Our analysis finds that audit committees possessing greater levels of financial expertise are associated with higher audit fees. When we segregate financial expertise between accounting and non-accounting, we find that the positive impact identified is driven by non-accounting expertise. Furthermore, when we separate FTSE100 and FTSE250 firms we find the impact of financial expertise is confined to FTSE250 firms. Our findings are important as they highlight the usefulness of segregating financial expertise between specialists and non-specialists, something which regulators in the UK and in the USA currently do not do. Our findings also highlight the potential value of audit committee expertise in smaller as opposed to larger listed firms, suggesting that the value of expertise to audit quality depends on the specific financial reporting challenges firms face.     

The effect of audit market structure on audit quality and audit pricing in the private-client market

This study examines whether audit market structure affects audit quality and audit pricing. We analyze two conceptually distinct dimensions of market structure: audit market concentration and client mobility. Focusing on the private-client segment of the Belgian audit market, we compare the pricing and quality effects of market structure between the segment of small and medium-sized (SME) clients and the segment of large clients to test how audit complexity moderates such effects. We find that market concentration impairs price and quality competition in the SME-client segment. Market concentration is unrelated to audit quality in the large-client segment, where we argue that concentration is endogenous to audit complexity. Furthermore, we find that client mobility stimulates price competition in both segments but improves audit quality only in the large-client segment. We interpret our findings as evidence that (a) audit market concentration impairs competition especially when audits have low complexity and that (b) the large-client market segment, characterized by higher audit complexity and higher market concentration, can also be price and quality competitive if clients are sufficiently mobile, and change auditors relatively frequently.     

Gender equity in public accounting: Evidence from single audit partner and director engagement leaders

While women are hired in equal numbers to men in public accounting, they are not proportionately promoted to partner, reflecting “vertical gender segregation.” This study examines vertical segregation in director positions which are an alternative terminal destination to the partnership. Using a U.S. non-profit setting, our results demonstrate that directors signing single audit reports are more likely to be female after controlling for client and signer characteristics, a clear pattern of gender-based vertical segregation among engagement leaders. This finding provides insights into practices which divert women to lower prestige director positions. In a supplemental test, we also find a fee premium for female partners but a fee discount for female directors, which may lead to gender-bias in compensation. These findings are particularly timely considering the disproportionate effect of the COVID-19 pandemic on women.     

How audit effort affects audit quality: An audit process and audit output perspective

Using a unique dataset of audit days in China from 2006 to 2011, this paper examines the relationship between audit effort and audit quality from the perspective of audit process and audit output. The results show that audit effort significantly increases the probability of audit adjustments, which inhibits positive earnings management and improves the quality of audited financial statements. We also find that audit effort does not have a significant effect on the issuance of modified audit opinions overall, but that a modified audit opinion is more likely to be issued in the absence of an audit adjustment. Furthermore, we find that the impact of audit effort on audit quality is attenuated when clients are more complex and when audit firms are larger. Collectively, our evidence suggests that audit effort plays an important role in improving audit quality by influencing audit process and audit output. Our study extends the literature on the impact of audit effort on audit quality in emerging markets, and the conclusions have important implications for the improvement of China’s audit market efficiency.     

The impact of the input level of information system audit on the audit quality: Korean evidence

In response to the increasingly sophisticated corporate information system environment in producing accounting data, audit firms are undertaking information system (IS) audit in addition to conventional auditing. This study focuses on examining the impact of input level of IS audit on audit quality. We collected data on IS audit hours, a unique reporting requirement for Korean listed-firms as disclosed in the External Audit Implementation Details beginning in 2014. Simultaneously, we used the amount of discretionary accruals and measure of conservatism, C_Score as the proxies of the audit quality. By empirically examining a sample set that includes 2,370 corporate-year observations from the Korea Composite Stock Price Index (2014–2018), we found that IS audit hours and IS audit personnel had a statistically significant negative correlation when estimating with amount of discretionary accruals using the model of Kothari et al. (2005) and positive correlation with C_Score. Even when the group was divided into Big 4 and non-BIG 4, these results were apparent in firm samples that were audited by Big 4 audit firms, whereas those audited by non-Big 4 firms did not show these results. Taken together, the following conclusion can be derived. Audit quality has improved through conducting IS audit in response to new types of audit risks that have emerged because of the use of information technology in corporations. Significantly, this study analyzes empirically the effect that the effort of IS auditing has on improving audit quality by using a unique reporting requirement for Korean-listed firms. The study confirms that an appropriate level of IS audit input can improve audit quality. In addition, it is meaningful that IS audit practice is following the risk-based approach of the Clarified International Standards on Auditing (ISA).     

Audit office size,audit quality and audit pricing: evidence from small- and medium-sized enterprises

Using Swedish data, we investigate how audit quality and audit pricing vary with audit firm and office size. In contrast to prior studies, we use disciplinary sanctions issued against auditors not meeting the quality requirement as the measure of audit quality. We find no significant differences in the likelihood of sanctions between Big 4 audit firms and the fifth and sixth largest audit firms in Sweden (Grant Thornton and BDO). We refer to these collectively as ‘Top 6’. However, we find that the probabilities of warnings or exclusions from the profession are much higher for non-Top 6 auditors in Sweden than for Top 6 auditors. Furthermore, we find a strong negative association between the likelihood of sanctions and audit office size for non-Top 6 auditors. This association is insignificant for Top 6 audit firms. Audit fees follow a similar pattern and indicate that larger audit firms and offices put in more effort or have greater expertise. These results suggest that audit quality is differentiated in the private segment market. However, contrary to prior studies, our results suggest that the important dimensions are Top 6 versus non-Top 6 and the office size of non-Top 6 audit firms.     

Place attachment,audit pricing and audit quality

Place attachment is an affective bond whereby people interact with and describe themselves as belonging to specific places. This study investigates the presence of place attachment in the auditing process. Using a large sample of listed clients in China, the findings reveal that auditors are likely to charge higher fees if their colleges are located in the same cities or provinces as their clients, supporting the familiarity bias hypothesis. This effect is more concentrated among smaller auditors, non-state-owned clients, and clients who switch auditors between years. In addition, a negative relationship is found between audit quality and geographical connections between auditors and clients. Overall, the results indicate the existence of place attachment in the auditing process.     

Effect of international working experience of individual auditors on audit quality: Evidence from China

This paper investigates the effects of auditors with international working experience on audit quality in emerging markets. Such auditors are associated with better audit quality, a pattern that is further supported by an examination based on a propensity score matching sample that controls for endogeneity. Chief financial officers with international experience are more conservative in the client company of their auditors who have international working experience. Further, reviewer partners with international working experience provide better audit quality in terms of low accruals, less below‐the‐line items, and less audit reporting aggressiveness, while engagement partners with international working experience require high audit fees. Moreover, financial reports signed by auditors with international working experience significantly increase analyst forecast accuracy and decrease analyst forecast dispersion. Our results are robust to different specifications and alternative measures. Overall, this paper highlights the importance of human capital and provides direct evidence on how auditors with international working experience use their knowledge and audit skills in emerging markets.     

Relation between external audit fees, audit committee characteristics and internal audit

This study examines whether the existence of an audit committee, audit committee characteristics and the use of internal audit are associated with higher external audit fees. Higher audit fees imply increased audit testing and higher audit quality. We find that the existence of an audit committee, more frequent committee meetings and increased use of internal audit are related to higher audit fees. The expertise of audit committee members is associated with higher audit fees when meeting frequency and independence are low. These findings are consistent with an increased demand for higher quality auditing by audit committees, and by firms that make greater use of internal audit.     

Risk-preparedness mechanism and audit quality: Evidence from mandatory increase of professional indemnity insurance and professional risk fund

We examine the risk-preparing benefits of Chinese audit firms’ professional indemnity insurance (PII) and professional risk fund (PRF) by using the Notice on Adjusting the Application Requirement of Audit Firms for Securities Qualifications as an exogenous shock. This policy requires audit firms to raise the sum of the cumulative compensation limit of their PII and PRF from 6 million to 80 million yuan. It is found, first, that the capital market regards this policy revision as a signal to strengthen investor protection and responds positively; client firms with high audit risks have a stronger response. Second, auditors’ governance of financial information has strengthened, resulting in the significant improvement of their clients’ financial reporting quality, with a stronger effect on firms with higher earnings management risk. There is no evidence that audit firms pass the costs on to their clients. Finally, the mismatch between auditors and new client firms is alleviated. We show that in an emerging market with weak investor protection, establishing a sound risk-preparedness mechanism for audit firms and strengthening the capacity for civil compensation ex post greatly improve the adaptive degree between international auditing standards and the legal environment of China, thereby enhancing the overall service quality of the audit market.     

Positive spillover effect and audit quality: a study of cancelling China’s dual audit system

The mandatory dual‐audit and dual‐reporting system (DADRS) for mainland Chinese firms cross‐listed in Hong Kong (AH firms) was abolished in 2010. This study quantifies a positive spillover effect from Hong Kong‐based auditors in the DADRS and examines whether and to what extent this affects the audit quality of AH firms. We find that AH firms exposed to a stronger positive spillover effect have higher audit quality, and the loss of this effect drives the declining audit quality of AH firms after they cancelled the DADRS. This study is among the first empirical works on this research topic.     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.
