Small audit firms with membership in an accounting association or network perform higher-quality audits than small firms that do not belong to such organizations, according to a new study by accounting researchers at the University of Arkansas.

The study also revealed that the quality of audits by small firms participating in an association or network was comparable to the quality of audits done by the largest public accounting firms, the so-called “Big 4.”

“Our findings should be of particular interest to audit committees tasked with auditor selection, because they suggest that, on average, membership in an accounting association, network or alliance provides small audit firms with additional resources that enable them to overcome barriers to performing high-quality, public company audits,” said Kenneth Bills, coauthor of the study and assistant professor of accounting in the Sam M. Walton College of Business.

The study, to be published in The Accounting Review, is the first to investigate the benefits of membership in an accounting association for small audit firms. It follows a report by the Advisory Committee on the Auditing Profession, provided to the U.S. Department of Treasury, which stated that small audit firms faced difficulties performing large public-company audits because they sometimes lacked “global resources and technical and industry expertise to deal with an increasingly complex business and financial reporting environment.” The researchers tested the report’s recommendation that association membership could benefit small audit firms.

Bills and co-authors Linda Myers, Distinguished Professor of Accounting, and Lauren Cunningham, an assistant professor of accounting at the University of Tennessee and former doctoral student in the Walton College, collected membership data from association websites for all associations in two publications, the Annual Directory of CPA Firm Associations and Networks and the Top 30 Accounting Networks and Associations, for 2010 through 2013. They focused on firms other than the “Big 4” – Deloitte and Touch, Ernst and Young, KPMG, and PwC, the four largest public accounting firms.

The researchers examined three measures of audit quality – restatements, discretionary accruals and inspections deficiencies – as defined by the Public Company Accounting Oversight Board. The board sets standards for audits of public companies and inspects audits of public companies performed by public accounting firms.

Restatements occur when there is something incorrect in a company’s financial statements, and the company is forced to reissue, or restate, its financial statements with the error corrected. Discretionary accruals are non-cash adjustments to a company’s balance sheet that management has discretion in determining and therefore could manipulate to make the financial statements appear better than they are. Inspection deficiencies are shortcomings found by the Public Company Accounting Oversight Board in its inspections of public-company audits performed by public accounting firms.

Small audit firms that were members of an association or network charged higher fees than nonmember firms, the study found. However, these firms did not charge as much as the four largest public accounting firms.

“The results we found are interesting because they indicate that association members provide audits of similar quality to the Big 4, but at a lower price,” Bills said. “A major caveat of the study, however, is that the results may not generalize to very large public companies for whom smaller audit firms lack adequate workforce to take on and complete their audits.”
