Auditee Incentives for Auditor Independence: The Case of Nonaudit Services

SYNOPSIS AND INTRODUCTION: The purpose of this research is to test the effects of agency incentives and knowledge spillovers in joint engagements for audit and nonaudit services. External parties and regulators have associated joint nonaudit purchases with beliefs about impaired auditor independence. Since reductions in perceived independence correspondingly reduce audit credibility, agency theory suggests that auditees have an incentive to limit nonaudit purchases because of the agency costs imposed when an audit's monitoring value is diminished. The frequency of nonaudit services is expected to reflect knowledge spillovers from joint engagements and the level of economic bonding between the auditor and the auditee. Hence, two categories of services are examined, recurring and nonrecurring. Agency incentives are expected to significantly influence the auditee's decision to purchase recurring nonaudit services since the auditor's revenue from a recurring service can be perceived as an annuity. However, for a nonrecurring service, future knowledge spillovers and incremental economic bonding are expected to be minimal. Because the auditor's revenue from the nonrecurring service is not an additional annuity, any perceived impairment to independence and credibility caused by incremental economic bonding should be limited. Data from Fortune 500 companies, disclosed under Accounting Series Release (ASR) No. 250, are used in multiple regressions to test whether auditees vary nonaudit purchases in accordance with the potential agency
