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.     

Adoption and content of key audit matters and stock price crash risk

We examine whether the mandate for auditors to report key audit matters (KAMs) affects firm-specific stock price crash risk in China. Auditors in China are required to issue an expanded audit report that contains KAMs for AH-share firms, effective on January 1, 2017 (applicable to the financial year 2016), and for A-share firms, effective on January 1, 2018 (applicable to the financial year 2017). Applying a staggered difference-in-differences (D-i-D) design on a sample of 18,751 observations for financial years 2012–2019, we find that auditor reporting of KAMs is not significantly associated with stock price crash risk. The mechanism tests show that the disclosure of KAMs does not reduce information opaqueness and managerial opportunistic behaviors. Furthermore, our findings are not sensitive, but are robust to firms' corporate governance, product market competition, ownership structure, and auditor size. Overall, our study informs regulators, investors, auditors, and other stakeholders interested in the economic consequences of mandating KAM disclosures.     

State ownership, the institutional environment, and auditor choice: Evidence from China

This paper finds that compared with non-state-owned firms, Chinese state-owned enterprises controlled by province, city, and county governments (local SOEs) are more likely to hire small auditors within the same region (small local auditors). In regions with less developed institutions, SOEs controlled by central government (central SOEs) also have such a tendency. However, the tendency of local and central SOEs to hire small local auditors is attenuated as the institutions develop. This auditor choice pattern is likely to be explained by SOEs’ lack of demand for large or non-local auditors, small local auditors’ superior local knowledge, and SOEs’ collusion incentives.     

Mandatory audit firm rotation: Fresh look versus poor knowledge

Our aim in this paper is to investigate the effects of mandatory audit firm rotation (MAR) on companies’ investment decision and auditor choice in a capital market setting. We compare a MAR regime with a non-MAR regime in a setting in which auditors’ independence and companies’ opinion shopping are real concerns. To capture auditor independence and opinion shopping, we model auditor biases (a conservative bias or an aggressive bias) and client firms’ incentives to engage auditors with desired biases. We find that when firms engage in opinion shopping, MAR improves investment efficiency for some firms but impairs investment efficiency for other firms. More generally, we contribute to the literature by demonstrating the real effects of auditing on corporate resource allocation decisions.     

Institutional Ownership and the Selection of Industry Specialist Auditors

This study provides evidence linking corporate governance mechanisms to the choice of auditor, namely industry specialists. Given that institutional investors are likely to prefer higher quality financial reports to lower quality reports, we theorize that institutional investors will influence managers of companies in which they invest to improve reporting quality by using higher quality, industry specialist auditors. Our findings indicate that firms having relatively greater levels of institutional ownership tend to employ industry specialist audit firms. The results of this study contribute to an understanding of an important facet of corporate governance, the selection of a high quality audit firm.     

Agency conflicts and auditing in private firms

We are interested in understanding how agency conflicts in private firms arise through ownership structures and family relationships. Specifically, we analyze auditors’ increase of effort and firms’ choice of auditors in situations with higher level of agency conflicts. For a large sample of private firms, we use unique and confidential data (obtained through special permission by the government) to measure direct and ultimate ownership for each shareholder as well as extended family relationships (based on marriage and blood lines, going back four generations and extending out to fourth cousin) among all shareholders, board members, and CEOs. We first find that audit fees, our proxy for audit effort, vary as hypothesized with firm-level characteristics related to ownership structures and family relationships. Second, we find evidence that firms in higher agency cost settings respond by having their financial statements audited by a higher-quality auditor (i.e., a Big 4 firm). However, for CEO family-related settings (i.e., where the CEO is related to the major shareholder or as the number of board members related to the CEO increases), we find no evidence of a greater demand for a Big 4 auditor.     

Effects of audit committee chair characteristics on auditor choice,audit fee and audit quality

We investigate whether the characteristics of audit committee (AC) chairs are associated with decisions about auditor choice, audit fees and audit quality. Using hand-collected Australian data, firms with AC chairs who have longer tenure and multiple AC memberships across several boards are found to be more likely to choose Big 4 and/or industry specialist auditors, pay higher audit fees and have lower discretionary accruals. Those AC chairs with higher business qualifications are more likely to hire a Big 4 auditor, pay higher audit fees and have lower discretionary accruals, while AC chairs with professional qualifications are more likely to hire a Big 4 and/or industry specialist auditor. In contrast, firms with AC chairs who are executive directors are less likely to hire a Big 4 auditor and have higher discretionary accruals. Our findings contribute to the literature by documenting that various characteristics of AC chairs are important for enhancement of auditor selection and audit quality.     

An international study of internal audit function quality

We investigate organisational and environmental factors that influence firms’ incentives to develop high-quality internal audit functions (IAFs) by using a unique international sample formed by matching proprietary data from a global internal auditor survey with public data obtained from Worldscope. Concerning organisational factors, we find that a positive relationship exists between IAF quality and firm complexity and confirm that complex firms have a higher demand for monitoring and advising and, therefore, a greater need for formal controls. In addition, IAF quality is positively related to board monitoring and audit committee diligence but negatively associated with CEO power, which suggests that IAF quality is influenced by other key players in corporate governance. Regarding environmental factors, we document that IAF quality is positively associated with industry competition, which implies that a firm’s incentive for a high-quality IAF is enhanced when confronted with greater environmental uncertainty. Furthermore, IAF quality has a significantly positive relationship with our self-constructed index of IAF requirements included in national corporate governance codes, which indicates that strong home-country corporate governance codes play a role in fostering IAF development.     

供应商-客户关系与审计师选择

采用2002-2009年中国制造业上市公司数据,本文检验了供应商集中度和客户集中度对公司审计师聘用决策的影响。研究结果显示,对于非国有公司来说,供应商集中度或客户集中度越高,公司聘用大所进行审计的概率越低。对于国有公司来说,随着供应商集中度或客户集中度的上升,公司聘用大所进行审计的概率先逐渐下降,但随后又逐渐上升,呈现出U型关系;但是,这种U型关系只在国有股比例较高的公司中存在。本文的研究结果表明,公司会通过聘用高质量的审计师向供应商或客户发送信号,换言之,审计信号理论对于投资者之外的利益相关者也是适用的。     

Auditor Selection: What Influences Decisions by Listed Companies?

Major business failures, including Enron and World Com in the United States and Harris Scarfe and HIH in Australia, and related alleged audit failures, have put the choice of auditor on the agenda. The choice of the "right" auditor has economic consequences for an auditee and implications for corporate governance. This paper discusses factors important to explaining auditor choice, including institutional factors (pertaining to the auditee and auditor) and newer emerging criteria as well as networking between directors and auditors. The paper discusses the relevant research and the policy implications for good corporate governance of auditor choice in publicly listed companies.     

Audit committee financial expertise,corporate governance,and the voluntary switch from auditor-provided to non-auditor-provided tax services

A prime objective of the SOX is to safeguard auditor independence. We investigate the relation between audit committee quality, corporate governance, and audit committees' decision to switch from permissible auditor-provided tax services. We find that firms with more independent boards, audit committees with greater accounting financial expertise, higher stock ownership by directors and institutions, that separate the CEO and Chairman of the board positions, and with higher tax to audit fee ratios are more likely to switch to a non-auditor provider. Further, we document that firms are more likely to switch prior to issuing equity. We find no evidence that broad financial expertise on audit committees is related to the switch decision, suggesting that the SEC's initial narrow definition of expertise is more consistent with the objective of the SOX. Overall, our results suggest that accounting financial expertise and strong corporate governance contribute to enhanced audit committee monitoring of auditor independence.     

The Value of Management Letters to Unlisted Companies

This paper reports the results of research on the value of management letters to unlisted companies. The aims of the research were: (1) to identify the issues raised in management letters; (2) to assess the value of management letters to unlisted companies; and (3) to assess the value of management letters to auditors. Within these aims we investigated whether the size of the audit firm (Big 5, Top 20, or other) or the length of audit tenure had any effect on the contents of management letters or their value to unlisted companies. We conclude that the issues most frequently raised in management letters related to internal control and accounting systems but that other issues, such as taxation and general business advice, are often included. There was little difference in the contents of management letters issued by Big 5 audit firms and other firms. Unlisted companies generally considered that the advice given in management letters was valuable. Again, there was little difference between clients of Big 5 audit firms and other firms. Similarly, the length of audit tenure had no statistically significant effect. Finally, auditors considered that the most important benefit of the management letter to themselves was its potential for enhancing clients’ perceptions of the auditor. The potential for reducing costs was relatively unimportant. These results were similar both for Top 20 and non-Top 20 audit firms.     

制度环境、审计供求与审计治理——基于我国证券市场中审计师变更问题的实证分析

本文基于我国证券市场中审计师变更问题这一动态视角考察了制度环境对外部审计治理的影响。通过研究,我们发现:首先,在制度环境发展相对落后的地区,上市公司频繁更换审计师的现象更严重;其次,在制度环境发展相对较好的地区,上市公司更可能发生审计师升级变更,表明其对高质量审计服务的需求;第三,在制度环境发展较差的地区,由于诉讼风险和诉讼成本较低,继任审计师为了获得审计客户更容易发生变通审计意见的行为,说明审计师难以发挥其外部治理的功能进而弥补制度环境的缺陷。本文的研究发现说明制度环境同时影响审计需求和审计供给两方面的行为表现,并支持了制度环境与外部审计治理是相互促进的关系。     

The impact of the Social Security Fund on auditor litigation risk

In this study, we examine the effect of the Social Security Fund on auditor litigation risk. Using audit fees as a proxy for auditor perceptions of litigation risk, we find that the Social Security Fund significantly reduces auditor litigation risk. Furthermore, we show that the Social Security Fund influences auditor litigation risk through reducing both the audit risk and the business risk of public companies. In addition, the impact of the Social Security Fund for reducing auditor litigation risk is more obvious in the group of firms with low levels of internal governance, which indicates that the Social Security Fund plays an important governance role as a high-quality institutional investor. In summary, we verify that the Social Security Fund, when acting as an institutional investor, plays an important role in corporate governance, and that it helps to reduce auditor litigation risk. Our results provide empirical support for expanding the governance role of the Social Security Fund as an institutional investor in China’s A-share market.     

Audit committee diligence around initial audit engagement

Studies focusing on governance mechanisms argue that auditor monitoring is one of several governance mechanisms that exist in the firm, and these mechanisms supplement each other. Extending this argument, I examine whether firms support auditor monitoring with audit committee monitoring when auditor oversight is deemed to be weak. Prior auditing literature argues that audit quality is affected by auditors' lack of familiarity with their clients' activities. Since lack of auditor–client familiarity exists in the first year of auditor–client tenure, I examine whether firms increase their audit committee monitoring during the year of auditor change. For a sample of firms that changed auditors between 2006 and 2012, the findings show that audit committees meet more frequently in the first year of audit engagement. Further tests show that firms' past reporting behavior play a significant role in the demand for more audit committee meetings and the increase in the audit committee meetings in the initial year of auditor engagement positively affects reporting quality.     

The association between employee stock option disclosures and corporate governance: Evidence from an enhanced disclosure regime

This study examines the role of corporate governance in employee stock option (ESO) disclosures following the revision of AASB 1028 Employee Benefits in 2001. We find that, while firms do not fully comply with AASB 1028 ESO disclosures, they voluntarily provide other ESO disclosures. In relation to corporate governance measures that have a role in the financial reporting process, we find two corporate governance measures dominate our results—the quality of auditor and duality of the role of CEO and Chair of the Board of Directors. We show that, in general, external auditor quality has positive incremental association with both mandatory and voluntary ESO disclosures while the dual role of CEO and chairperson of the board is associated with lower levels of mandatory disclosure.     

Audit value and charitable organizations

I examine whether donors favor charities that use high quality auditors and whether the propensity to donate varies directly with audit quality. I find that audit quality affects donor decisions in the market for contributions. From a signaling perspective, charities benefit simply from engaging a higher quality auditor. From an information perspective, donors are more sensitive to changes in reported accounting information verified by a high quality auditor. I also find that, after conditioning on the charity’s reputation, donors are still willing to give more to charities aligned with a quality auditor, but the effect of audit quality choice dissipates with the size of the charity. Thus, a charity’s reputation and the choice of auditor are substitute mechanisms for signaling the credibility of financial information to donors.     

Culture and auditor choice: A test of the secrecy hypothesis

The purpose of this study is to investigate whether firms’ auditor choice relates to national culture. We construct a novel measure of secretiveness based on Hofstede [Hofstede, G., 1980. Culture’s Consequences: International Differences in Work Related Values. Sage Publications, Beverly Hills, CA] cultural factors. Using a very large sample of firms from 37 countries and controlling for a number of firm- and country-level factors, we find that firms in “more secretive” countries are less likely to hire a Big 4 auditor. We also document that the relation between secrecy dimension of national culture and auditor choice is mitigated by the firms’ degree of internationalization. These results establish a link between national culture and financial reporting quality through the firm’s choice of auditor.     

Race to the top or bottom? Corporate governance,freedom of reincorporation and competition in law

Summary This paper investigates the governance structure choices of firms when there is competition between legal systems. We study the impact of the allocation of control over choice of governance and reincorporation on firms’ technologies and technological specialization of countries in the context of a model of the firm in which there are agency conflicts between shareholders and managers. We show that the allocation of control over firms’ reincorporation decisions determines the corporate governance choice ex ante and the outcome of the competition between legal regimes ex post. When managers have control over reincorporation then competitive deregulation and “runs to the bottom” ensue. When shareholders have partial or full control then there is diversity in governance structures. Runs to the bottom are not necessarily socially undesirable but they have a feedback effect on firms’ choices of technologies that may make the party in control worse off ex ante. We show that it is impossible for any country to achieve social welfare maximization of its existing and new enterprises. With competition between legal regimes, start-up and mature companies incorporate in different jurisdictions even when reincorporation is correctly anticipated.     

Performance and governance in microfinance institutions

We examine the relationship between firm performance and corporate governance in microfinance institutions (MFI) using a self-constructed global dataset on MFIs collected from third-party rating agencies. Using random effects panel data estimations, we study the effects of board and CEO characteristics, firm ownership type, customer-firm relationship, and competition and regulation on an MFI’s financial performance and outreach to poor clients. We find that financial performance improves with local rather than international directors, an internal board auditor, and a female CEO. The number of credit clients increase with CEO/chairman duality. Outreach is lower in the case of lending to individuals than in the case of group lending. We find no difference between non-profit organisations and shareholder firms in financial performance and outreach, and we find that bank regulation has no effect. The results underline the need for an industry specific approach to MFI governance.
