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.     

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 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.     

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.     

Audit firm, corporate governance, and audit quality: Evidence from Bahrain

The aim of this research is to document the perceptions of credit and financial analysts with regard to the relationship between the effectiveness of audit committee, size of the auditing firm and audit quality in the context of Bahrain, which is characterized by a developed financial sector, low-liquidity stock market, low turnover in board of directors of listed firms, an inactive merger and acquisitions market and almost non-extent litigation. A survey of 300 credit and financial analysts shows that analysts considered auditors' opinion useful. Both credit and financial analysts see the credibility of financial statements to be a function of the size of the auditing firm. Both groups assume that the characteristics of Big-Four firms allow them to produce better-quality reports than non-Big firms. Non-audit services were found to affect auditor's independence and hence impair audit quality. Both the groups of analysts believe that effective audit committee enhances the quality of audit reports. Financial analysts perceive financial statements to be more credible than do credit analysts.     

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.     

Consequences of fraud and overcoming negative market reaction

We examine the market reaction to a sample of firms following the announcement of the firms' involvement in fraud, referred to as the trigger event. We find that these firms experience negative and significant returns following the announcement of fraud, in contrast to a control sample. More importantly, we examine tactics, such as changes in executives, auditing firm, and company name, that these firms may use to regain the market's confidence. We find that the market reacts negatively right after the change in executives, but the negative trend is reversed in the long-term for firms that make an executive change quickly after the trigger event. Similarly, firms that quickly change their auditing firm fare better. We also find that there is significantly more information asymmetry during the trigger event and at the litigation date, as well as during changes in CEO, CFO, and auditor. We find a prompt change in CFO is positively and significantly related to, and therefore predicts, better long-term stock performance.     

Audit firm merger and the strategic response by large audit firms

We examine the impact of a change in the audit industry structure in China as a result of two recent mergers involving large non-Big 4 audit firms. The ‘New Big’ audit firms, Ruihua and BDO Lixin, became the third and fourth largest audit firms in China following audit firm mergers, outranking both EY and KPMG in terms of total audit revenues in 2013. We find a significant audit fee and audit quality increase for the New Big audit firms relative to the Big 4 audit firms following the mergers. While this finding could be interpreted as an increase in quality as a result of audit firm consolidation, we find that this net effect is due to a decrease in audit fees and audit quality for the Big 4 following the mergers, rather than an increase in audit fees and audit quality by the New Big audit firms. We discuss the implications of our findings for various regulators.     

Stock market reactions to US Consumer Product Safety Commission enforcement actions

This study examines stock market reaction to violations of product safety regulations and firm product responsibilities in the post-enforcement period. Our event study results show that market reaction was negative to failures by firms to report product defects in a timely way. Our results also show that the stock market reaction varies depending on the type of violations, and whether there are single or multiple violations. Firms spend more on research and development and advertising in the post-enforcement period, in addition to investing in their compliance programmes which have a significant positive impact on product responsibility stewardship. Our empirical results show that the stock market reacts negatively to recall volume and refund remediation strategy. The stock market reaction is negative to social media communication about product recalls initiated by manufacturers. However, this negative effect appears to be counteracted by the positive corporate social responsibility (CSR) reputation effect of the manufacturers. Our findings imply that US manufacturing firms dealing with product recalls must be sensitive to how consumers and investors interpret the communication.     

The Emergence of Second‐Tier Auditors in the US: Evidence from Investor Perceptions of Financial Reporting Credibility

We examine changes in the association between auditor type (Big 4, Second‐Tier, and Other non‐Big 4) and perceived financial reporting credibility in the wake of events (e.g., Andersen's failure, the implementation of SOX, creation of the PCAOB, etc.) which led to significant growth in Second‐Tier client portfolios and increased scrutiny of Second‐Tier audit practices. Our results reveal that financial reporting credibility of Second‐Tier clients was lower than that of Big 4 clients and was indistinguishable from that of Other non‐Big 4 clients pre‐Andersen. However, post‐Andersen, we find that financial reporting credibility of Second‐Tier clients is higher than that of Other non‐Big 4 clients and is indistinguishable from that of Big 4 clients. We expect that our results will be of interest to regulators, both in the United States and in the European Union, who have expressed concerns about the current state of competition in the audit market, management and boards of directors that are contemplating switching to a Second‐Tier audit firm, and academics investigating quality differences among audit firm types.     

The effect of audit firm size on audit prices: A study of the Australian Market

The effect of audit firm size on prizes is a complex function of competition in the market for audit services, product differentiation, and scale economics to large firms. In this study, a competitive market is supported in Australia with product differentiation to Bif Eight accounting firms. Specially, Big Eight accounting firms have significantly higher audit prices than non-Big Eight firms. This results holds for ‘large’ and ‘small’ auditees. A test is also made of price cutting in the Australian market. Price cutting is defined as lower initial audit fees than continuing engagement fees for a comparable audit. Test results do not evidence price-cutting behavior by accounting firms. There is in fact weak evidence that initial audit fees are higher than continuing engagement fee levels. Higher initial fees suggest that accounting firms may recover at least some of the audit start-up costs immediately.     

Subjectivity in fair-value estimates,audit quality,and informativeness of other comprehensive income

This study empirically examines whether difference in audit quality is reflected in the pricing of other comprehensive income (OCI). Specifically, we first investigate whether OCI measures of Big 4 clients are more value-relevant than those of non-Big 4 clients. Considering different degrees of subjective management judgment involved in the OCI reporting process, we then explore whether the differential valuation effect of OCI between Big 4 and non-Big 4 clients is more pronounced for more subjective OCI components (e.g., minimum pension liability and foreign currency-translation adjustment) than a less subjective component (e.g., marketable securities adjustment). We predict that the aggregate OCI of a Big 4 client is more value-relevant than that of a non-Big 4 client. We also hypothesize that the differential valuation effect between Big 4 and non-Big 4 clients can be attributed to the amount of subjective assumption and judgment required in estimating OCI. Consistent with our predictions, we find that aggregate OCI audited by a Big 4 auditor has incremental information content over earnings, compared to OCI audited by a non-Big 4 auditor. More interestingly, our results also show that the differential valuation effect between Big 4 and non-Big 4 clients is stronger for OCI components of a more subjective nature. Our results are robust even after controlling for self-selection bias, the potential effect of the financial crisis, and other related effects.     

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.     

Empirical Evidence on the Implicit Determinants of Compensation in Big 4 Audit Partnerships

This study investigates the implicit financial incentives of individual Big 4 audit partners by examining the association between a partner's compensation and characteristics of the audit firm, audit partner, and individual partner clientele for Big 4 firms in Sweden. Using tax and financial data for individual audit partners and clients, our empirical findings indicate that there is significant variation in the implicit determinants that are associated with compensation across the Big 4. We find that audit partners’ compensation is positively associated with the size of their clientele or the number of publicly traded clients, both of which represent revenue‐generating opportunities. Similarly, compensation and developing an industry specialization are positively related. In three firms, gaining clients is clearly related to an increase in compensation, while losing a client is associated with a reduction in partner income in only one firm. We find that audit partner income is more sensitive to performance‐related incentives, such as attracting new clients, as partners progress in their career. Finally, we find evidence that audit failures, proxied by reporting errors related to issuing a going concern opinion, are associated with lower compensation. These results should be of interest to the auditing profession, audit firms, and regulators when they consider the effects of implicit incentives of partner compensation on audit quality.     

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.     

Economic impact of political barriers to cross-border acquisitions: An empirical study of CNOOC's unsuccessful takeover of Unocal

In 2005, the US Congress challenged the acquisition by CNOOC (a Chinese state-owned enterprise) of Unocal (a US firm). This challenge creates a political barrier for foreign companies to acquire US oil companies. This paper examines the stock price reaction of US oil companies to this political opposition. Using an event study methodology, we find that this political barrier resulted in a substantial decline in the market value of US oil companies. For a period of 44 days, during which six anti-CNOOC-takeover political events occurred, the cumulative decline in the market value of a portfolio of 13 US oil refining firms was $47.5 billion and that of a portfolio of 66 US oil and gas exploration firms was $11.4 billion. This study is the first to analyze and quantify the stock price reaction of US non-merging firms to political barriers to cross-border acquisitions. It also has a policy implication regarding the recent enactment of the Foreign Investment and National Security Act of 2007.

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).     

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.     

A meta-analysis of factors affecting acceptance of information technology in auditing

Technology advancements provide opportunities for auditors to use new tools in the audit process. This study presents a synthesis of technology-related auditing research to identify factors affecting the use of technology in auditing. We analyze 88 studies in identifying 21 factors relevant to technology acceptance in auditing based on country of origin (developed or developing), user type (external or internal), type of technology (traditional or advanced), firm size (Big 4 or non-Big 4), and publication time (before and after 2013). Our results show that the most important factors in accepting technology from an individual perspective are facilitator conditions, perceived usefulness, and understanding of ease of use. Technology acceptance factors relevant to an organizational perspective are cost-benefit technology, competitive pressure, company readiness, and matching technology-task. Results suggest that perceived usefulness and subjective norm are more important in developed countries and Big 4 audit firms, while auditors in developing countries and non-Big 4 audit firms are more influenced by perceived ease of use, facilitating conditions, and organizational factors. Adopting traditional technologies is also more influenced by understanding the ease of use, subjective norms, and top management support than advanced technologies. This study contributes to the literature by assessing technology acceptance factors in auditing and thus provides policy, practice, and research implications.
