U.S. Global Network Firms Inspection Data

These graphs reflect data included in the public portion of the inspection reports of six registered U.S. firms: Deloitte & Touche LLP (DT); Ernst & Young LLP (EY); KPMG LLP (KPMG); PricewaterhouseCoopers LLP (PwC); BDO USA, P.C. (BDO); and Grant Thornton LLP (GT).

The inspection data below is readily ascertainable from the public portion of the inspection report, but the data should be understood in light of contextualizing information provided with each report, including (1) it relates only to the audits selected for review, which does not constitute a representative sample of the firm’s total population of issuer audits, and only to the particular portions of the issuer audits reviewed; (2) for various reasons, inspection results are not necessarily comparable over time or among firms; (3) inspection results are not an assessment of all of the firm’s audit work nor of all of the audit procedures performed for the audits reviewed; and (4) inspection reports are not intended to serve as overall rating tools.

2023 Inspection Results

2023 Inspection Part I.A Deficiency Rate

Part I.A Deficiencies

An audit deficiency is cited and described in Part I.A of an inspection report if it is of such significance that we believe the firm, at the time it issued its audit report(s), had not obtained sufficient appropriate audit evidence to support its opinion(s) on the issuer’s financial statements and/or internal control over financial reporting (ICFR).

Classification of Audits Reviewed

In our inspection reports, we classify each issuer audit reviewed in one of the categories shown in the graph based on the Part I.A deficiency or deficiencies identified in our review. The purpose of this classification system is to group and present issuer audits by the number of Part I.A deficiencies we identified within the audit as well as to highlight audits with an incorrect opinion on the financial statements and/or ICFR when applicable.

Audits Selected for Review

Audits Selected for Review by Audit Type

We select both integrated audits of financial statements and ICFR and audits of financial statement only.

Audits Selected for Review by Selection Method

We use a combination of risk-based and random methods to select issuer audits for review. Because our inspection process evolves over time, it can, and often does, focus on a different mix of issuer audits and audit areas from year to year and firm to firm. In addition, we utilize a target team of inspectors to perform inspection procedures in areas of current risk and emerging topics. More information on the focus of the target team procedures in each year can be found in the relevant inspection report.

Deficiencies by Audit Areas and Auditing Standards

Audit Areas Most Frequently Reviewed

These are the audit areas we have selected most frequently for review across all six firms and the number of issuer audits by focus area with and without Part I.A deficiencies. For the issuer audits selected for review, we selected these areas because they were generally significant to the issuer’s financial statements, may have included complex issues for auditors, and/or involved complex judgments in (1) estimating and auditing the reported value of related accounts and disclosures and (2) implementing and auditing the related controls.
