Research Question
What are the effects of audit firm changes and audit partner rotation on the reporting of internal control deficiencies?
![Page 4: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/4.jpg)
Motivation
Implications for understanding the costs and benefits of audit firm and audit partner changes– Financial reporting misstatements and low accrual quality
are associated with internal control weaknesses– Control risk assessment is important for planning substantive
audit procedures– Lack of client specific knowledge may lead to over- or
under-reliance on internal controls (i.e. ineffective or inefficient audit program)
– Auditors’ choices about whether and how to report control deficiencies can influence stakeholders’ decision-making
![Page 5: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/5.jpg)
The Not-for-Profit Sector Setting
The U.S. federal government relies on internal control attestation to monitor federal award recipients– Focus on controls supports compliance with laws and regulations– Helps to ensure appropriate administration of federal awards
NFPs have financial incentives to invest in internal controls– Federal agencies and private donors decrease funding following
disclosure of internal control deficiencies
Two unique features of this setting:– A-133 audit reports disclose material weaknesses, significant
deficiencies, and exceptions in the controls and substantive testing– Audit partner is observable
![Page 6: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/6.jpg)
Hypotheses
![Page 7: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/7.jpg)
Audit Firm Changes (H1)
Control deficiencies may be reported more frequently following audit firm changes due to initial year audit procedures– Professional standards require auditors to invest in gaining client-
specific knowledge in the initial year, including the control environment
– Prior studies document higher audit hours in the first year of an engagement
Predecessor auditors may not have reported known control deficiencies in prior years
– Escalation of commitment may influence auditors’ assessments of the severity of detected internal control deficiencies
![Page 8: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/8.jpg)
Audit Firm Changes (H1) (cont)
Control deficiencies may be reported less frequently following audit firm changes if a high degree of client-specific knowledge is needed to evaluate controls effectively– Auditors may place greater reliance on management representations
due to lack of client specific knowledge– Prior studies commonly document lower accrual quality in the early
years of the auditor-client relationship
H1: Audit firms are no more likely to report internal control deficiencies in the initial year of audit firm tenure
![Page 9: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/9.jpg)
Audit Partner Rotation (H2)
Partners may develop relationships with their clients over time that potentially compromise auditor independence
Audit partner rotation may result in an increase in reported control deficiencies
– Partner rotation may bring a “fresh look” to the engagement– Partners increase planned procedures in their initial year on an
engagement
![Page 10: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/10.jpg)
Audit Partner Rotation (H2) (cont)
Control deficiencies may not be reported more frequently following audit partner rotation– Client-specific knowledge is carried forward in work papers– Other client personnel are not required to rotate– Survey evidence indicates that U.S. audit partners need two years
to gain client-specific knowledge
H2: Audit partners are no more likely to report internal control deficiencies in the initial year of audit partner tenure on a continuing client.
![Page 11: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/11.jpg)
Audit Partner Tenure (H3)
No clear prediction for how control deficiency reporting varies with audit partner tenure– Audit partners have incentives to protect their reputational capital– Audit partners may be susceptible to cognitive biases over
successive audits– Studies on audit partner tenure from other securities markets
(Australia, Taiwan) provide mixed evidence on the relation between audit partner tenure and audit quality
H3: Audit partners are no more likely to report control deficiencies on clients with longer partner tenure.

The Not-for-Profit Sector
As a component of the U.S. economy, the NFP sector:– Contributes 5% of GDP– Employs 10% of the U.S. workforce– GAO estimates $235 billion in federal awards reached the NFP
sector in 2006– NFPs benefit from $50 billion annually in foregone federal tax
payments
Growth of NFP sector has attracted Congressional scrutiny– NFPs can exploit their tax-exempt status to earn economic rents at
the expense of for-profit counterparts
![Page 14: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/14.jpg)
OMB Section A-133 Audit Reports
Federal award recipients submit audited financial statements and A-133 audit reports if federal expenditures exceed $500,000 during the year ($300,000 prior to 2004)
A-133 audit reports disclose material weaknesses and reportable conditions (significant deficiencies) over:
– Internal control over financial reporting– Compliance with major program requirements
Reports also include audit findings and questioned costs (i.e. exceptions identified in the control and substantive testing over major programs)
![Page 15: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/15.jpg)

Dependent Variables
Estimate logistic regressions where the dependent variable equals one if the audit report indicates:– Financial statement reportable condition (FS_RC)– Financial statement material weakness (FS_MW)
– An audit finding or questioned cost (FINDORQ)– Major program reportable condition (MP_RC)– Major program material weakness (MP_MW)
![Page 19: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/19.jpg)
Independent Variables
H1: CHANGEFIRM equals one if the client changed auditors from year t-1 to year t
H2: CHANGEPARTNER equals one if the audit partner changed from year t-1 to year t and CHANGEFIRM=0
H3: LONGTENURE equals one if audit partner tenure in year t exceeds 5 years
![Page 20: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/20.jpg)

Selection Model
Public companies are more likely to change auditors following an adverse internal control opinion
Follow Tate (2007) in modeling for audit firm changes in the NFP sector – Changes in contributions, revenues, expenses, liabilities,
compensation, and accounting fees– Augment with outcome variables, auditor’s client base, and
Andersen client, industry, year, and state indicator variables
ROC = 0.786, Pseudo R-Square = 0.243

H2 Additional Tests: Change Partner
Insignificant coefficient on CHANGEPARTNER:– Audit partners may have previous experience on the client, and so
do not bring “fresh eyes” to the engagement
– Audit partners require 2 years experience to gain familiarity with the client, so effects, if any, may arise in year 2
![Page 31: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/31.jpg)

H1 Additional Test: Change Firm
Is the positive significant coefficient on CHANGEFIRM:
– Due to the application of new audit methodology and initial year audit procedures?
– Or did the predecessor auditor fail to report known deficiencies in prior years

Sensitivity Tests
Results are consistent :– Controlling for prior audit partner tenure– Controlling for or excluding former Andersen partners and clients– In annual cross sectional regressions– Examining only “first time” control deficiencies
![Page 37: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/37.jpg)
Summary of Findings
Auditors are more likely to report all categories of control deficiencies in the initial year of the auditor-client relationship
No differences in reported control deficiencies in years of audit partner changes
Long audit partner tenure is associated with higher likelihood of reported findings and questioned costs
![Page 38: Brian Fitzgerald Thomas Omer Texas A&M University Anne Thompson The University of Illinois Audit Partner and Audit Firm Rotation and the Assessment of.](https://reader037.fdocuments.us/reader037/viewer/2022110101/56649ee15503460f94bf2593/html5/thumbnails/38.jpg)
Conclusions and Contributions
Contributions to the literature on the costs and benefits of audit firm changes and audit partner rotation:– New audit firms’ investment in understanding controls appears to
lead to an increase in reported control deficiencies– May provide an explanation for why accrual quality improves with
audit firm tenure– No evidence supporting the notion that audit partner rotation
immediately provides a “fresh look”– Partner tenure exceeding 5 years may lead to higher audit quality
