Abstract
Using a large sample of U.S. bank loan data from 1996 to 2008, we investigate the relation between two auditor characteristics, namely, auditor size and tenure, and loan interest rates. Our results show the following: First, we find that the loan interest rate is significantly lower for borrowers with prestigious Big 4 auditors than for borrowers with non-Big 4 auditors. Second, we find that auditor tenure is negatively associated with the loan interest rate, suggesting that a long client–auditor relationship lowers the loan borrowing cost. Third, we find that the negative association between auditor size and loan rate is more pronounced for transaction-based term loans than for relationship-based revolving loans. Fourth, our sub-period tests show that our results are driven by the post-Sarbanes–Oxley Act period. Our study provides direct evidence that auditor size and tenure are incremental credit risk-reducing factors in the bank loan market.

Notes
Bank loans have consistently accounted for more than 50% of total debt financing in the United States (Graham et al. 2008) since 1980. The volume of syndicated loans reached $1.69 trillion in 2007 according to the DealScan database.
To our knowledge, three studies examine the role of audits per se in loan pricing. Johnson et al. (1983) provide experimental evidence suggesting that auditor association is not a significant factor affecting bank loan rates. Blackwell et al. (1998) investigate the economic value of various levels of audit assurance (i.e., audits, reviews, compilations) using a small sample private firms. Kim et al. (2011a) examine the effect of voluntary, non-statutory audits on interest expenses (relative to short- and long-term debts) using a sample of privately held Korean firms. Both Blackwell et al. (1998) and Kim et al. (2011a) report evidence that audits per se lead to a lower loan rate or a lower interest rate. However, none of the above studies investigate the relation between auditor size or tenure and bank loan rate.
Lenders in the loan market include banks and other private lenders, such as investment banks, insurance companies, and other institutional investors. This paper uses the terms banks and lenders interchangeably, since commercial banks are the major suppliers of private debt.
However, focusing on bonds issued by private firms via private placements, Fortin and Pittman (2007) fail to determine that choosing a higher-quality Big 4 auditor significantly affects credit rating and yield spread.
For instance, a deal can comprise a line of credit facility and a term loan with longer maturity.
Generally, accelerated filers are public companies that have been a public company for at least 12 calendar months, have filed at least one annual report, are not “small business issuers,” and have public float (the aggregate market value of the voting and non-voting common equity held by non-affiliates of the company) of $75 million or more. Non-accelerated filers must begin including the management’s assessment of internal control effectiveness in annual reports for fiscal years ending on or after December 15, 2007, and the auditor’s attestation in annual reports for fiscal years ending on or after December 15, 2008.
In an additional test, we measure an auditor’s industry specialization based on its share of clients’ total assets in each two-digit SIC industry. Though not reported, the results are similar to those reported in Table 7.
In our sample, all industry specialist auditors are Big 4 auditors.
