Rules of engagement – How CPA ethics rules affect your experts

Description

Abstract: Rule 101 of the American Institute of Certified Public Accountants (AICPA) Code of Professional Conduct requires CPAs to be “independent in the performance of professional services.” AICPA Interpretation 101-3, Performance of Nonattest Services, describes several nonattest services that, if performed for an attest client, impair a CPA’s independence. A recent controversial revision to Interpretation 101-3 added expert witness services to the list of activities that impair a CPA’s independence. This article notes the importance of expert witness independence and the impact on litigation.
