The results suggest that fees paid to auditors, even for non-audit services, can potentially threaten auditor independence, particularly among banks that are not subject to the same level of regulatory scrutiny as large banks.

In first-year audits, lower audit process quality and higher total audit hours are possible additional costs that should be considered in the ongoing debate on mandatory audit firm rotation. Moreover, study results are consistent with the notion that—even prior to the effective date of the Sarbanes-Oxley Act (SOX)—market and related regulatory forces disciplined auditors of public entities to achieve a high level of audit quality when tenure was long or fees from auditor-provided non-audit services were large. In order to serve the public interest, these considerations should be included in assessments of the economic costs and benefits of restrictions on audit firm tenure and non-audit services.
Furthermore, the results suggest that, in the private-client market, audit process quality declines in the long tenure range and when non-audit fees become large, which may be of interest to standard setters in the private sector (e.g., the Auditing Standards Board and US State Boards of Accountancy).

The lower quality and higher effort associated with first-year audits represent additional costs that should be considered in the ongoing debate on mandatory audit firm rotation. The differential findings for private and public clients suggest that market and related regulatory forces discipline auditors of SEC clients to maintain a high level of audit quality even when tenure is long or NAS fees are high. The findings are important for regulatory policies related to audit firm tenure and auditor-provided NAS. The finding that quality declines in private-client audits as NAS fees increase or tenure becomes long should be of interest to standard setters in the private sector.

The results of this study show that in general market-based incentives, such as loss of reputation, constitute more important factors with regard to auditor independence than an economic dependence caused by higher non-audit fees. However, those safeguards may not be adequate in all situations given the relatively low litigation risk in Germany. The relatively high importance of consulting services performed in audit engagements by the Big 4 group seems to give Big 4 auditors an incentive to continue the auditor-client relationship, and is therefore to be regarded as an additional economic dependence between auditor and client. The explicit representation of liquidity risks through management appears to influence auditor reporting behavior in relation to going concern risks. This information—even if it is not presented in a separate reporting instrument, such as the Lagebericht—could also determine auditor reporting behavior outside Germany.

The authors contribute by providing some of the first evidence of service bundling in the economics of auditing literature. In doing so, they broaden the notion that strategic pricing occurs around audit switches. This study contributes to prior mixed findings of the existence of industry specialist premiums in the small-client segment, suggesting an additional reason why these mixed findings might occur. Where opportunities to package services are attractive, auditors may strategically price and discount audits with bundling premiums in mind. Where potential for such bundling opportunities is less attractive, it is possible the auditor may instead seek to generate premiums in the audit service.

The results of this study have implications to both New Zealand and the United States. Regulators in New Zealand should assess these results as possible indications that the profession’s self-regulated status may need to be revised in light of the existence of lower financial reporting quality for clients that have weak audit committee oversight and are economically important clients to the auditor. Additionally, these results provide evidence to contribute to the ongoing debate in the United States regarding the merits and the intended and unintended consequences of independent auditor oversight through regulatory bodies such as the PCAOB.

This study serves the purpose of examining the PCAOB’s role as overseer of public company auditing, while separating from previous studies by targeting the PCAOB’s restrictions on auditors’ tax services, which have not been examined in the past. This study also examines whether APTS pose a threat to audit quality but again differentiates itself from previous literature by focusing on only the tax services that the PCAOB chose to ban and by utilizing the difference-in-differences design to address the limitation of the cross-sectional approach utilized by other studies in the past. After reviewing these findings, it is possible that the PCAOB restrictions did not fully accomplish their objective.

This study presents new evidence that suggests the presence of AFAPs and UFAPs on the audit committee has the potential to reduce threats to auditor independence by pre-approving the purchase of less NAS form the auditor. The findings of this study are consistent with the view that AFAPs serving as independent audit committee members appear not to make economic decisions in favor of their former audit firm, and, thus, may be exercising objective and independent oversight to enhance auditor independence. This evidence is also in line with the goal of SOX to reduce actual or perceived threats to auditor independence. From a regulatory perspective, the findings suggests that concerns about audit firm alumni on client’s audit committees may not be warranted in the post-SOX environment and the three-year cooling period rule may be unnecessary. However, further research in other contexts is needed.

This paper added to the discussion on what types of services audit firms should and should not provide to their audit clients. The evidence in this paper supports the view that investors do not view tax services provided to audit clients in the same light as audit-related services. The findings of this study are relevant to managers and boards of directors who purchase non-audit services (audit-related, tax or other) from the external auditor. This study is also useful to practicing auditors to address audit committee concerns on non-audit services.

The authors contribute to the literature in three ways. First, the results provide support for the agency-based demand for publicly available audit quality signals in a powerful test setting. They find SOX supply-side approach of banning certain NAS may have hurt some registrants if those banned NAS services previously served to increase overall audit quality. Second, the evidence provided herein suggests that registrants learned from the market’s negative price protection reaction and, in accordance with agency theory, recalibrated their subsequent year NAS purchases. Finally, the results provide archival, empirical support for the audit committee incentive arguments of Gaynor et al.
