Audit Partner Characteristics, Audit Quality and Audit Pricing in the U.S. Ally Zimmerman, Northern Illinois University, azimmerman5@niu.edu Al Nagy, John Carroll University, alnagy@jcu.edu 2016 Deloitte/KU Audit Symposium, May 20 8/16/2016 1

Introduction  RQ: Do audit fees and audit quality vary among U.S. audit partners with partner experience and gender?  Studies from other countries have found audit partner effects, but evidence is mixed  U.S. audit market different from other countries  Litigious environment, regulatory scrutiny/inspections  No Disclosure of audit partner identity to investors  No U.S. evidence yet - Partner identity disclosure will be required in the U.S. starting in 2017 on PCAOB Form AP  Contribution  Understanding the impact of individual auditors on audit outcomes over and above their audit firms/offices  What can data from the period 2004-2014 prior to disclosure of audit partner identity tell us about the impact of audit partner characteristics on audit pricing, quality?  Evidence pre- and post-disclosure can be compared in the future to isolate the impact of audit partner identity disclosure itself 8/16/2016 2

Prior Research Outside of U.S. In Australia, Taylor (2011) finds that premium partners audit fewer clients than the • discount partners, but on the contrary have shorter partner tenures. In Sweden, partner industry specialization is positively associated with audit fees • (Zerni 2012). Ittonen and Peni (2012) find that firms with female audit engagement partners have • significantly higher audit fees. Gul et al. (2013) identify significance of audit partner effects on audit outcomes in • China. In Australia, Goodwin and Wu (2014) find that audit fee premiums are associated with • partner-level industry expertise. Ye, Cheng, and Gao (2014) document that individual auditors with more auditing • experience are less likely to be associated with audit failure. Hardies et al. (2015) also find a female audit fee premium among Belgian public • companies. Cahan and Sun (2015) find that experience is positively associated with audit fees in • China. Wang et al. (2015) find that, in some models of restatements, engagement and review • partner experience is positively related to restatements (audit failures). 8/16/2016 3

Does Partner Experience Matter in U.S.? • Audit partner identity matters to management and audit committees in the auditor selection process • Partners/their resumes are heavily vetted in the auditor selection process. • Technical expertise as well as political capital within an audit firm arguably takes years to develop. • Technical/industry expertise is associated with higher audit quality • If partner political capital and expertise are valuable to clients, they would be willing to pay more for it through higher audit fees. H1a/b: Audit partner experience is positively associated with audit fees and audit quality. 8/16/2016 4

Does Partner Gender Matter? • Females executives tend to be more diligent, more conservative, less overconfident and less tolerant of risk than males (e.g., Palvia et al. 2015; Huang and Kisgen 2013; Peni and Vahamaa 2010; Eagly and Carli 2003) -> Higher audit quality • Female tolerance for less risk may affect the pricing decisions by increasing auditor effort. • If females tolerate less risk, they may also charge a premium for taking on this risk. H2a/b: Female audit partners have higher audit fees and higher audit quality than male audit partners. 8/16/2016 5

Data and Sample We identified through Audit Analytics SEC Comment Letter Database a • total of 6,562 SEC comment letter correspondences from 2004 to Oct 2014 that copied 1,750 unique Big 4 audit partners Correspondences could copy more than one audit partner; if more than • one partner copied, assumed the first person copied was the lead partner We assumed that the copied audit partner was an engagement partner on • the audit of the firm in the year of the letter (alternatively the prior year based on CompuStat year) Partner background information hand-collected from LinkedIn • Excluded financial firms, foreign-based, those missing model variable • information and who partner information could not be located Final sample for analysis – 769 firm-year observations encompassing 479 • unique firms and 471 unique partners – Some firms and partners but not all have multiple appearances 8/16/2016 6

GENDR = 1 if partner is female, 0 if male. ASSETS = log of total assets. ROA = ratio of net income to total assets. LEV = ratio of long-term debt to total assets. LOSS = 1 if company had a net loss in last 3 years, else 0. NSUBS = log of the number of consolidated subsidiaries. REC = ratio of receivables to total assets. INV = ratio of inventory to total assets. GC = 1 if going concern modification in the audit report, else 0. FORSA = ratio of foreign sales to total sales. DECYE = 1 if December fiscal year-end, else 0. S404 = 1 if integrated SOX 404(b) and external audit is conducted, else 0. SPEC = 1 if auditor is national specialist per SIC code (2-digit), else 0. TEN = 1 if auditor tenure is less than 3yrs 8/16/2016 8

Results Summary • Strong Results for Audit Pricing – More experienced audit partners associated with higher audit fees – Female audit fee premium • Mixed Results for Audit Quality – More experienced partners are more independent -> more likely to issue a going concern modified opinion for distressed companies – No difference in audit quality/ independence with respect to partner gender 8/16/2016 14
