Auditor choice and accruals patterns of cross-listed firms

We examine the association between auditor choice and the accruals patterns of Chinese listed firms that cross-list in Hong Kong. Our evidence suggests that the clients of Big 4 auditors report lower unsigned discretionary accruals relative to the clients of non-Big 4 auditors. Further, we find that cross-listed firms with non-Big 4 auditors are more likely to understate their earnings and experience larger reversals of accruals in the future than cross-listed firms with Big 4 auditors. These findings suggest that Big 4 auditors play a meaningful role in improving earnings quality for cross-listed firms, which helps to explain why cross-listed firms have higher earnings quality than their domestic counterparts, as documented in the previous literature.     

Auditor Market Share,Product Differentiation and Audit Fees

This study examines the effects of auditor market share and product differentiation on audit fees. Previous studies have attributed the price premium charged by the Big Eight (the Big Six in the present study) to Big Eight product differentiation. However, such a price premium could be partly due to monopoly pricing. In the present study, the Hong Kong audit market provides a unique setting in which a non-Big Six local auditor has a market share comparable to those of the third and fourth largest Big Six firms. This makes it feasible to control for the effects of market share via matching. Also, the wide disparity among the Big Six firms ‘market shares in Hong Kong makes it feasible to test for the effects of market power on audit fees. The results show that, consistent with prior studies, the Big Six audit firms charge higher audit fees than non-Big Six firms in the small auditee, but not the big auditee, market. This suggests that similar economic forces to those other audit markets are also at work in Hong Kong. Despite the Big Six firms’ widely different market shares, there was no price differentiation among them. Yet there was a Big Six price premium over the large local firm with a similar market share to those of two of the Big Six. Together, these results suggest that the Big Six price premium is a result of product differentiation rather than monopoly pricing.     

Audit Reporting of Big 4 Versus Non-Big 4 Auditors: The Case of Ex-Andersen Clients

This paper examines audit reporting of Big 4 auditors versus non-Big 4 auditors for ex-Andersen clients and other clients. It suggests that ex-Andersen clients are more risky than other clients and are able to exert more influence than other clients on non-Big 4 auditors because they are larger in size than other non-Big 4 auditees. In addition, Big 4 auditors are more risk-averse and able to withstand clients' pressure than non-Big 4 auditors. The results show that Big 4 auditors are more likely than non-Big 4 auditors to issue going-concern opinions to ex-Andersen clients or restrict the level of discretionary accruals of those clients compared with other clients. Further, ex-Andersen clients of Big 4 auditors would have had a lower likelihood of receiving going-concern opinions or higher levels of discretionary accruals had reporting practices for other clients been applied. Ex-Andersen clients of non-Big 4 auditors would have had a higher likelihood of going-concern opinions or lower levels of discretionary accruals. Hence, the suggestion to reduce the Big 4 concentration in the audit market by allowing non-Big 4 firms a larger market share should be viewed prudently. Overall, these results are consistent with the suggestion that litigation risk and client pressure are important factors in audit reporting.     

Big Six auditors and audit quality: The Korean evidence

This study investigates the association between discretionary accruals and Big Six and non-Big Six auditors, and the direction of auditor change. We hypothesize that there is no significant difference in discretionary accruals between Big Six and non-Big Six clients when there is low incentive for auditors to provide high-quality audits, as in Korea.Upon examination of the discretionary accruals of firms listed on the Korean Stock Exchange from 1994 to 1998, we find there is no significant difference between the discretionary accruals of firms with Big Six and non-Big Six auditors. This holds true for firms that switch from non-Big Six to Big Six auditors and vice versa. These resources imply that there may be no difference in audit quality between Big Six and non-Big Six auditors in Korea. This is consistent with other studies in Korea, while inconsistent with the findings of previous studies on audit quality in other countries.     

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.     

The endogenous relationship between audit-report type and business termination: evidence on private firms in a non-litigious environment

This study provides evidence on the relationship between audit-report type and subsequent business termination for private companies in a non-litigious environment. The results show that an endogenous relationship exists between bankruptcy and audit-report type, and between voluntary liquidation and audit-report type. A non-clean opinion is typically issued when firms face financial difficulties, which in turn become more severe after the receipt of a non-clean audit opinion. We find evidence that, even without a litigation deterrent in Belgium, financial performance has a similar impact on audit-report type as in litigious environments. We find that the self-fulfilling prophecy hypothesis holds for bankruptcy but not for voluntary liquidation. Our study also provides some evidence on audit reporting differences between Big 6 and non-Big 6 auditors in the Belgian audit market. When financial difficulties are obvious, as is the case when a company is about to go bankrupt, both Big 6 and non- Big 6 auditors are as competent and/or independent to assess and report going-concern problems. However, when financial difficulties are less apparent, as is the case for firms that voluntarily decide to liquidate, our results indicate that Big 6 auditors are more likely to issue a non-clean audit opinion than non-Big 6 auditors.     

Barriers to entry to the big firm audit market: Evidence from market reaction to switches to second Tier audit firms in the post-sox period

The US Government Accountability Office (GAO) studied concentration in the audit market and found that the Big 4 firms continue to dominate the market for clients with revenue of more than $500 million while non-Big 4 firms have gained market share among clients with revenue of $500 million or less (GAO, 2008). The US Treasury Advisory Committee on the Auditing Profession has expressed concern about barriers to entry that might prevent a non-Big 4 firm from increasing its market share among large publicly-traded clients (Advisory Committee, 2008). One of these barriers may be the potential cost to shareholders if the stock market reacts negatively to the appointment of a non-Big 4 auditor (GAO, 2003). We examine whether the stock market reacts negatively when clients switch from a Big 4 to a non-Big 4, because a negative reaction might make such switching less likely to occur. We find that the market does not react more negatively when clients move from a Big 4 to a Second Tier auditing firm than when clients move from a Big 4 to another Big 4 firm. Our results suggest that a negative market reaction may not represent a significant barrier to entry among Second Tier auditing firms.     

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.     

Does corporate social responsibility affect auditor-client contracting? Evidence from auditor selection and audit fees

We find that firms with higher CSR performance are more likely to choose Big N auditors and less likely to switch to non-Big N auditors, consistent with socially responsible firms demanding higher audit quality. Furthermore, we provide robust evidence that firms with higher CSR performance pay lower audit fees using both levels and changes models, suggesting that higher CSR performance reduces auditor engagement risk. Our analysis based on the difference-in-differences approach indicates that it is higher CSR performance that leads to lower audit fees, not vice versa. Overall, the results highlight the important role of CSR performance in auditor-client contracting.     

How individual auditor characteristics impact the likelihood of audit failure: Evidence from China

Audit failure imposes a severe loss on investors and damages market participants' confidence in financial reporting quality. This study investigates the impacts of individual auditor characteristics on the likelihood of audit failure. Chinese regulators mandate listed firms to disclose the engagement auditors' identity. Furthermore, the information regarding individual auditor characteristics in China is also publicly available. Utilizing this unique setting, we examine the relationship between individual auditor characteristics and the likelihood of audit failure in China during the period from 2000 to 2009. We document that individual auditors with more auditing experience are less likely associated with audit failure. We also find a weaker negative relationship between auditor education level and audit failure. Our study has important implications for both auditors and regulators by shedding lights on the determinants of audit failure and by providing guidance to the human resource management in audit firms.     

Independent and joint effects of audit partner tenure and non-audit fees on audit quality

We examine the individual and joint effects of auditors’ non-audit services (NAS)/abnormal NAS fees and length of audit partner tenure on audit quality. Our results raise questions about the ‘one size fits all’ approach imposed by the current audit partner rotation requirement in Australia as a result of (1) a learning differentiation that we observe between Big 4 and non-Big 4 auditors and (2) higher discretionary accruals associated with non-Big 4 auditors. We find abnormal NAS fees to have a positive association with both absolute and positive (income-increasing) values of discretionary accruals for firms with short audit partner tenure. NAS/abnormal NAS fees are also negatively associated with the issuance of going concern opinions to financially distressed firms when partner tenure is short. In terms of policy implications, regulators are able to gauge the efficacy of the CLERP 9 reforms which currently impose a five year mandatory audit partner rotation requirement.     

Auditor changes following big eight mergers with non-big eight audit firms

This paper examines the reaction of clients of “non-Big Eight” audit firms to mergers of their auditors with “Big Eight” firms. We postulate that a non-Big Eight audit firm's clients will retain a Big Eight acquirer following a merger if they benefit from the Big Eight firm's specialized services and/or reputation. Clients that do not have these economic incentives to retain the Big Eight firm are more likely to change to another non-Big Eight audit firm following the merger. Empirical tests of the characteristics of clients that remain with a Big Eight acquirer or change to another smaller auditor following an audit merger generally support our hypotheses.     

Client importance and audit partner independence

We use data from Taiwan where audit partners are required to sign audit reports to examine whether audit partners compromise their independence for economically important clients. Uniquely, we include both listed and unlisted clients in audit partners’ client portfolios and separately study these clients for Big N and non-Big N auditors. We employ multiple proxies for auditor independence, including various abnormal accruals measures, the propensity of audit partners to issue modified audit opinions, and the probability that clients meet or just beat earnings targets. We fail to find evidence that Big N audit partners compromise their independence for economically important clients; however, we find such evidence for non-Big N auditors. Our results are robust to a battery of sensitivity analyses. While our inferences are limited to the Taiwanese capital market, our study may be of interest to market participants and regulators in other well developed capital markets.     

Is the market valuation of banks’ loan loss provision conditional on auditor reputation?

We examine how auditor reputation conditions the market valuation of banks’ loan loss provision (LLP). The inherent uncertainty associated with and discretion permitted in estimating the LLP contributes to information asymmetry. The auditor’s certification and monitoring roles influence firm value by mitigating this information asymmetry. We examine two aspects of auditor reputation, auditor type (Big 5 vs. non-Big 5) and auditor expertise, in the banking industry. We find a significant, positive association between the discretionary component of LLP and stock return for banks audited by the Big 5 auditors. Further analysis indicates that auditor expertise within banking and not auditor type drives this significant, positive association. Overall, our results are consistent with auditor expertise in the banking industry mitigating information asymmetry between bank managers and investors and enhancing the information conveyed by discretionary loan loss provision.     

Foreign ownership and auditor choice

We take advantage of the unique institutional background of the B-share stock market in China to explore the impact of foreign investors on auditor choice. Our results show that the percentage of B-share firms audited by Big 4 auditors has decreased with both economic and statistical significance since the segmented B-share market was opened to domestic investors in 2001. We find that the negative effect of opening the B-share market on demand for high audit quality is more pronounced for firms with greater decreases in foreign ownership and for firms with strong incentives to be opaque, such as those in a weak institutional environment, firms with more “other receivables,” firms with more related-party transactions, and firms with political connections. Additional analysis shows that our results are not driven by the concurrent decline in capital-raising activities in the B-share market.     

Acquirers’ abnormal returns and the non-Big 4 auditor clientele effect

I analyze the effect of auditor choice on acquirers’ values around merger announcements and the factors affecting the interaction between auditor size and the market reaction to merger announcements. I find that acquirers audited by non-Big 4 accounting firms outperform those audited by Big 4 firms. This effect is more pronounced when the targets are privately held and when the likelihood of the auditors playing a prominent advisory role increases. While the largest auditing firms are usually assumed to offer superior services, the study suggests that smaller firms have a comparative advantage in assisting their clients in merger transactions.     

Audit pricing and auditor industry specialization in an emerging market: Evidence from China

In this paper we examine the determinants of audit fees by focusing on auditor industry specialization and second tier auditors in the Chinese market. We find evidence of Big 4 premiums for brand name as well as industry specialization in both the statutory and supplementary market. Big 4 industry specialists earn additional premiums in the statutory market as compared to non-industry specialists. We also find that market expansion did not provide the second tier auditors any price advantage. These auditors increased their market share mainly in the mid- and small-sized clienteles. Moreover, industry experience developed by the second tier firms may have helped them gain economy of scale and reduce service fees. This may be their strategy to win future clients that seek low-priced audits.     

Auditor Choice in Politically Connected Firms

We extend recent research on the links between political connections and financial reporting by examining the role of auditor choice. Our evidence that public firms with political connections are more likely to appoint a Big 4 auditor supports the intuition that insiders in these firms are eager to improve accounting transparency to convince outside investors that they refrain from exploiting their connections to divert corporate resources. In evidence consistent with another prediction, we find that this link is stronger for connected firms with ownership structures conducive to insiders seizing private benefits at the expense of minority investors. We also find that the relation between political connections and auditor choice is stronger for firms operating in countries with relatively poor institutional infrastructure, implying that tough external monitoring by Big 4 auditors becomes more valuable for preventing diversion in these situations. Finally, we report that connected firms with Big 4 auditors exhibit less earnings management and enjoy greater transparency, higher valuations, and cheaper equity financing.     

Determinants and implications of long audit reporting lags: evidence from China

Audit reporting lag is the single most important determinant influencing the timeliness of the release of financial statements. In this study, we first explore the determinants of audit reporting lags in China where the audit market for listed firms is dominated by non-Big 4 auditors. We then examine the implications of long audit reporting lags in subsequent years. We find that selected measures of audit risk and complexity, and auditor expertise are all associated with the length of audit reporting lags in China. Firms with long audit reporting lags are more likely to have the receipt of non-standard opinions in subsequent periods. There is also evidence that firms with extremely long audit reporting lags tend to have more restatements in the subsequent year. As prior research has not specifically investigated the consequences of long audit reporting lags in subsequent years, this study makes an important contribution to the literature in this area.     

Is there a relation between audit fee cuts during the global financial crisis and banks’ financial reporting quality?

As a result of the global financial crisis (GFC), several audit clients were able to negotiate lower audit fees for the years 2008 and 2009. However, the PCAOB has expressed concern that lower audit fees might lead to lower audit effort and lower audit quality and financial reporting quality. This study examines the relation between audit fee cuts and banks’ financial reporting quality. Specifically, we focus on earnings management via loan loss provisions (LLP), the relation between current period LLP and future loan charge-offs, i.e., LLP validity, and the timely recognition of loan losses. For banks audited by Big 4 auditors, we find that income-increasing abnormal LLP are decreasing in audit fee cuts and LLP validity is increasing in audit fee cuts. For banks audited by non-Big 4 auditors, LLP validity is higher for banks that received a fee cut of more than 25% relative to other banks audited by non-Big 4 auditors. We do not observe an association between timely loan loss recognition and cuts in audit fees except for banks audited by non-Big 4 auditors and exempt from internal control audits where a fee cut of more than 25% is associated with less timely loan loss recognition. Overall, the findings suggest that Big 4 auditors constrained earnings management via LLP in banks that received cuts in audit fees. Our findings have important implications for regulators, investors, and others.
