SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-101724; File No. PCAOB-2024-06]


Public Company Accounting Oversight Board; Notice of Filing of 
Proposed Rules on Firm and Engagement Metrics and Related Amendments to 
PCAOB Standards

November 25, 2024.
    Pursuant to Section 107(b) of the Sarbanes-Oxley Act of 2002 (the 
``Act''), notice is hereby given that on November 22, 2024, the Public 
Company Accounting Oversight Board (the ``Board'' or the ``PCAOB'') 
filed with the Securities and Exchange Commission (the ``Commission'') 
the proposed rules described in items I and II below, which items have 
been prepared by the Board. The Commission is publishing this notice to 
solicit comments on the proposed rules from interested persons.

I. Board's Statement of the Terms of Substance of the Proposed Rules

    On November 21, 2024, the Board adopted Firm and Engagement Metrics 
and related amendments to its rules and forms (collectively, the 
``proposed rules''). The text of the proposed rules appears in Exhibit 
A to the SEC Filing Form 19b-4 and is available on the Boards website 
at <a href="https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-041">https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-041</a>, and at the Commission's Public Reference Room.

II. Board's Statement of the Purpose of, and Statutory Basis for, the 
Proposed Rules

    In its filing with the Commission, the Board included statements 
concerning the purpose of, and basis for, the proposed rules and 
discussed any comments it received on the proposed rules. The text of 
these statements may be examined at the places specified in Item IV 
below. The Board has prepared summaries, set forth in sections A, B, 
and C below, of the most significant aspects of such statements. In 
addition, the Board is requesting that the Commission approve the 
proposed rules, pursuant to Section 103(a)(3)(C) of the Sarbanes-Oxley 
Act, for application to audits of emerging growth companies (``EGCs''), 
as that term is defined in Section 3(a)(80) of the Securities Exchange 
Act of 1934 (``Exchange Act''). The Board's request is set forth in 
section D.

A. Board's Statement of the Purpose of, and Statutory Basis for, the 
Proposed Rules

(a) Purpose
    The Board has adopted a set of firm- and engagement-level metrics 
(the ``final rules'' or ``final metrics'') that certain registered 
public accounting firms (``firms'' or ``audit firms'') will be required 
to publicly report relating to their audit practices and the audits 
they lead. The Board believes these metrics will provide valuable 
additional information, context, and perspective on auditors and audit 
engagements, which can be used by investors, audit committees, and 
other stakeholders, and which will further the Board's oversight 
activities. The Board believes this will advance investor protection 
and promote the public interest by enabling stakeholders to make 
better-informed decisions, promoting auditor accountability, and 
ultimately enhancing capital allocation and confidence in our capital 
markets. The new reporting requirements will apply to firms that audit 
at least one company that is an ``accelerated filer'' or ``large 
accelerated filer'' (as those terms are defined in SEC rules).\1\
---------------------------------------------------------------------------

    \1\ vSee 17 CFR 240.12b-2 (``Rule 12b-2'').
---------------------------------------------------------------------------

Lack of Consistent, Comparable Data About Audits and Auditors
    Investors and audit committees cannot easily observe the services 
performed by auditors. This can limit investors' ability to make 
informed decisions about investing their capital, ratifying the 
selection of auditors, and voting for members of the board of 
directors, including directors who serve on the audit committee, and 
audit committees' ability to choose among and monitor the performance 
of auditors. At the same time, there is a lack of incentive for firms, 
acting on their own or collectively, to provide accurate, standardized, 
and decision-relevant information about their firms and the engagements 
they perform. In response to these challenges, the Board has studied 
ways to measure audit firm and audit engagement performance, primarily 
with a view to providing information useful to investors in their 
investment and proxy voting decisions, but also recognizing that 
metrics could potentially be informative to other stakeholders. In 
addition, the Board itself would benefit from having additional tools 
to use in its oversight activities, including its inspections program, 
standard-setting initiatives, and research activities.
    The Board has observed that many of the firms that issue audit 
reports for more than 100 issuers annually and audit companies that 
account for the majority of U.S. public company market capitalization 
already publicly disclose certain firm-level metrics through audit 
quality reports, transparency reports, or similar documents. However, 
these disclosures generally do not contain engagement-level 
information, which investors have indicated would be the most useful to 
them, and are inconsistent across firms and year to year, with no 
common definitions or calculations that would allow for meaningful 
comparisons. Moreover, most of the disclosures are voluntary, so firms 
are free to revise or discontinue such reporting at any time.
    In the Board's view, the current voluntary reporting regime cannot 
provide consistent, comparable information that stakeholders can rely 
on to inform their decisions over time. And it would appear that firms' 
attempts at voluntary reporting have not, in fact, satisfactorily 
addressed investor desire for additional information about audits and 
auditors. On the contrary, support from investors and investor-related 
groups for this rulemaking initiative has been consistent throughout 
its history, even as the practice of firm voluntary reporting has 
evolved and spread.
Metrics at Firm and Engagement Level
    The final rules require reporting of metrics at both the firm and 
the engagement levels. Firm-level metrics relate to aspects of the 
firm's audit practice (e.g., average experience at a public accounting 
firm of the firm's partners) and engagement-level metrics relate to 
individual audit engagements (e.g., experience at a public accounting 
firm of the engagement partner and the engagement quality reviewer 
(``EQR'') and average experience of certain other engagement team 
members). The Board is requiring firm-level metrics because it believes 
information relevant to the firm will be beneficial in providing 
context for engagement-level metrics and in evaluating the firm's audit 
practice and its related system of quality control. The Board is 
requiring engagement-level metrics because it believes that information 
will be useful in gaining a richer understanding of a particular audit 
and because investors have stressed the importance to them of 
engagement-level information to assist them in evaluating the 
performance of the auditor and the audit committee. Most metrics will 
be reported at both firm- and engagement-level. However, the final 
rules require reporting at only

[[Page 99969]]

the firm level in cases where the Board believes engagement-level data 
would not be meaningful or would be disproportionally challenging to 
collect in relation to the incremental benefit.
Final Metrics
    The Board adopted metrics in the following eight areas:
    Partner and Manager Involvement. Hours worked by senior 
professionals relative to more junior staff across the firm's large 
accelerated and accelerated filer engagements and on the specific 
engagement.
    Workload. Average weekly hours worked on a quarterly basis by 
senior professionals who incurred hours on large accelerated and 
accelerated filer engagements, including time attributable to 
engagements, administrative duties, and all other matters, both firm-
wide and on the core engagement team.
    Training Hours for Audit Personnel. Average annual training hours 
for partners, managers, and staff of the firm, combined, both firm-wide 
and on the core engagement team.
    Experience of Audit Personnel. Average number of years worked at a 
public accounting firm (whether or not PCAOB-registered) by senior 
professionals across the firm and on the engagement.
    Industry Experience. Average years of career experience of senior 
professionals in key industries audited by the firm at the firm level 
and the audited company's primary industry at the engagement level.
    Retention of Audit Personnel (firm-level only). Continuity of 
senior professionals (through departures, reassignments, etc.) across 
the firm.
    Allocation of Audit Hours. Percentage of hours incurred prior to 
and following an issuer's year end across the firm's large accelerated 
and accelerated filer engagements and on the specific engagement.
    Restatement History (firm-level only). Restatements of financial 
statements and management reports on internal control over financial 
reporting (``ICFR'') that were audited by the firm over the past three 
years.
    Firms are permitted, but not required, to accompany the metrics 
with narrative disclosure to provide additional context.
    The final suite of metrics focuses primarily on information about 
audit personnel. The Board believes these metrics will provide new 
insights into how engagements are staffed, including the extent of 
involvement of senior personnel; auditors' overall workload; retention 
of personnel across the firm; and levels of training, audit experience, 
and industry-specific expertise. The final metrics will also provide 
information about the extent of audit work completed prior to the 
issuer's year-end, an aspect of the audit process that the Board 
believes is associated with improved audit outcomes, and about the 
firm's history of restatements, a key measure of audit outcomes.
    This new information will allow users to draw inferences about 
audits and audit forms that are not possible today. Some may relate to 
specific metrics. For example, a heavy workload for a particular 
engagement team relative to the firm average or compared to peer firms 
may raise questions about the quality of the work performed. 
Conversely, a relatively high level of industry experience, 
particularly for an engagement in an industry that benefits from 
specific accounting and auditing expertise, would be a positive signal. 
Other inferences may relate to combinations of metrics. For example, 
the personnel-related metrics, taken together, give an overall sense of 
how an engagement is staffed that can be compared to firm averages and 
to engagements for similar issuers. It is possible that the precise 
numerical values of metrics may be important in some cases but, in 
general, the Board believes the metrics will be more useful to convey a 
sense of whether a particular engagement or firm appears fairly typical 
or is an outlier in one or more respects. This should provide a richer 
context for understanding the work of the auditor than the current 
environment of almost no publicly available information.
    The Board also believes that gathering data and calculating the 
final metrics, given the subjects they address, will not be overly 
costly, time-consuming, or burdensome. Based on the Board's oversight 
activities, it appears that the largest firms are already tracking data 
in many of these areas. Many of the metrics are based on data that 
firms already track or will be required to track for purposes of other 
PCAOB requirements. For example, Partner and Manager Involvement and 
Allocation of Audit Hours are based on the same time reporting required 
for Form AP purposes. Training hours will reflect the same information 
that firms track to ensure proper licensing of their personnel. 
Restatement data, to the extent firms are not already tracking it, is 
required to be tracked under QC 1000. In addition to required data, 
many firms track the experience of their personnel, as well as industry 
experience, for use in marketing materials and for inclusion in 
requests for proposals, and some firms already track staff retention 
and turnover metrics as part of their human capital management. Firms 
should be able to generate other data required by the final metrics, 
such as Workload, from their existing timekeeping systems with minimal 
additional effort.
Responding to Commenter Concerns
    After considering commenter input, the Board has made a number of 
changes from the proposal. The final rules eliminate four proposed 
metrics areas (Audit Resources--Use of Specialists and Shared Service 
Centers, Audit Hours and Risk Areas, Quality Performance Ratings and 
Compensation, and Audit Firms' Internal Monitoring) and add one new 
metric area (Training Hours for Audit Personnel). In addition, only 
firm-level reporting will be required for one area (Retention of Audit 
Personnel) that was proposed to be reported at both the firm and 
engagement level. The Board has also made revisions to simplify and 
clarify some of the other metrics and exempted firms with a small 
issuer practice from reporting on their industry experience. In 
addition, the Board has expanded the optional narrative disclosure from 
500 to 1,000 characters and has provided additional direction that the 
narrative should be concise and focused on the reported metrics, with a 
view to facilitating the reader's understanding of the metrics. The 
Board believes that these changes will address commenter concerns about 
challenges of data collection, potential sensitivity of data, and 
potential ambiguity of the metrics, and that the final suite of metrics 
will provide consistent, comparable information on auditors and audit 
engagements, giving investors, audit committees, and other stakeholders 
valuable new context and perspective.
    The Board considered comments questioning the value of metrics, 
whether they will be used by investors and other stakeholders or would 
represent only a ``check the box'' compliance exercise, and whether 
they might contribute to information overload or have other negative 
consequences. Based on the other stakeholder input received, the Board 
does not share those views. In comments provided in the Board's 
rulemaking process and surveys conducted by a firm-related group, 
investors and investor-related groups have repeatedly indicated that 
the metrics will be useful. As one investor-related group noted:

    Auditors say they want to be seen or evaluated as something 
other than a commodity business evaluated based upon price. For this 
to happen, auditors need to provide investors with information such 
that

[[Page 99970]]

they can value the work of the auditor--just as they evaluate and 
value the business and the work of management.\2\
---------------------------------------------------------------------------

    \2\ Letter from CFA Institute, August 30, 2024, at 17.

    The Board also notes that similar objections--that the new 
information would not be used or would be confusing or misleading--were 
raised by many of the same commenters in connection with its last two 
rulemakings requiring disclosure of additional information about audits 
and auditors: Form AP reporting of the name of the engagement partner 
and information about other firms participating in the audit, and 
auditor communication of critical audit matters (``CAMs''). In both 
cases, these commenter concerns appear unsubstantiated. The Form AP 
data set is now one of the most frequently visited areas of the PCAOB's 
website.\3\ As for CAMs, while academic studies have shown mixed 
results about the impact of CAMs, in a recent investor survey conducted 
by a firm-related group, over 90% of the respondents indicated that 
CAMs play an important role in their investment decision-making.\4\ In 
addition, data aggregators, such as Audit Analytics, compile and make 
available data on CAMs, which suggests market demand for that 
information. The Board's experience therefore suggests that, contrary 
to concerns about irrelevance and information overload, stakeholders 
seek out additional information about auditors and audit engagements 
when it is available.
---------------------------------------------------------------------------

    \3\ In 2023, there were over 333,000 unique searches performed 
on AuditorSearch and the Form AP data set was downloaded over 2,000 
times. Information related to usage statistics can be found on the 
PCAOB's website (<a href="https://pcaobus.org/resources/auditorsearch">https://pcaobus.org/resources/auditorsearch</a>).

Filing Requirements
    Under the Board's final rules, firm-level reporting is required of 
every firm that audits at least one ``accelerated filer'' or ``large 
accelerated filer'' under SEC rules during the reporting period. 
Engagement-level reporting will be required for every audit of an 
accelerated or large accelerated filer. The thresholds will apply to 
the audits, and auditors, of companies that account for the majority of 
U.S. public company market capitalization, and the Board believes they 
will capture the situations where investment and proxy voting decisions 
will be most likely to benefit from additional information about the 
audit and the auditor.
    The final rules:
    <bullet> Require reporting of firm-level metrics annually on a new 
Form FM, Firm Metrics, pursuant to a new Rule 2203C, Firm Metrics, for 
firms that issued an audit report with respect to at least one 
accelerated filer or large accelerated filer during the reporting 
period;
    <bullet> Require reporting of engagement-level metrics for audits 
of accelerated filers and large accelerated filers on a revised Form 
AP, renamed ``Audit Participants and Metrics''; and
    <bullet> Allow, but not require, limited narrative disclosures on 
both Form FM and Form AP to provide context and explanation for the 
required metrics.
Background
    The final rules build on other actions the Board has taken to 
provide stakeholders with additional information about registered firms 
and the audits they perform, including information about firms 
available through its registration and reporting forms, information 
about auditors and engagements on Form AP, and communication of 
critical audit matters and auditor tenure in the auditor's report. The 
Board concurrently adopted other changes to firm reporting 
requirements.\5\ The Board believes the final rules will complement 
these efforts by providing investors, audit committees, and other 
stakeholders with additional information in a consistent format and 
compiled with sufficient rigor to assist them in making decisions. For 
example, the metrics could inform investors' decision-making regarding 
whether to ratify the audit committee's selection of an auditor or to 
vote for members of the board of directors, including directors who 
serve on the audit committee, as well as potentially assisting in audit 
committee oversight, supporting continuous improvement of firms' 
quality control systems, and facilitating the Board's own oversight and 
rulemaking efforts. The Board further believes that the value of these 
metrics will likely increase over time as firm reporting practices 
develop and trends become observable.
---------------------------------------------------------------------------

    \5\ See Firm Reporting, PCAOB Rel. No. 2024-013 (Nov. 21, 2024) 
(adopting amendments to reporting requirements for Form 2, Annual 
Report Form, and Form 3, Special Reporting Form).
---------------------------------------------------------------------------

    As in its proposal, the Board uses the term ``firm and engagement 
metrics'' rather than ``audit quality indicators'' (``AQIs'') to 
describe the metrics that it adopted. The Board believes this avoids 
the potential misimpression that any set of metrics can comprehensively 
measure audit quality and emphasizes the Board's goal of promoting 
informed decision-making through robust disclosure requirements. Some 
commenters were critical of that change in terminology, suggesting that 
it evidenced that the Board is no longer focused on audit quality. It 
is simply a clarification. Because some of the most important elements 
of a high-quality audit, such as application of due care and 
professional skepticism, cannot be measured and quantified directly, 
the metrics employ proxies, such as years of experience, auditor 
workloads, and percentage of audit hours attributable to more senior 
members of the engagement team, which can only partially capture these 
concepts. Even though these proxies cannot provide a complete picture 
of audit quality, the Board believes they will nevertheless convey 
important information about auditors and the engagements they lead that 
stakeholders will find relevant and useful. The Board believes that 
consideration of the metrics in combination, together with any 
additional context a firm may choose to provide, will help users 
interpret the data, and that the metrics, analyzed across firms and 
over time, will yield important, currently unavailable information that 
will assist investors, audit committees, and other stakeholders in 
their decision-making, oversight, and evaluation related to audits.
    The Board developed the proposal after considering input from 
numerous sources, including the recommendations of the U.S. Department 
of Treasury's Advisory Committee on the Auditing Profession (``ACAP''), 
including the October 6, 2008 Final Report of the Advisory Committee on 
the Auditing Profession to the U.S. Department of the Treasury (``ACAP 
Final Report''); the Concept Release on Audit Quality Indicators, PCAOB 
Rel. No. 2015-005 (July 1, 2015) (``Concept Release''), and the 
comments received; the voluntary practices of firms; recommendations 
from the PCAOB's Investor Advisory Group (``IAG''); and the initiatives 
of international regulators. The Board has carefully considered this 
input and believes that the final amendments strike an appropriate 
balance between the expected benefits of the new reporting requirements 
and the associated costs of implementation and compliance.
Effective Dates
    If the Commission approves the final rules and final metrics, both 
firm-level and engagement-level reporting will be required for periods 
beginning October 1, 2027. The Board also adopted a phased 
implementation period for both

[[Page 99971]]

firm- and engagement-level reporting, where firms that issue audit 
reports for more than 100 issuers will begin reporting in the first 
year that reporting is required and other firms beginning one year 
later.
(b) Statutory Basis
    The statutory basis for the proposed rules is Title I of the Act.

B. Board's Statement on Burden on Competition

    Not applicable. The Board's consideration of the economic impacts 
of the proposed rules is discussed in section D below.

C. Board's Statement on Comments on the Proposed Rules Received From 
Members, Participants or Others

    The Board released the proposed rules for public comment in PCAOB 
Release No. 2024-002 on April 9, 2024. Previously, the Board issued a 
concept release for public comment in PCAOB Release No. 2015-055 on 
July 1, 2015. The Board received over 45 comment letters in response to 
the proposing release and 50 letters in response to the concept 
release. See Exhibits 2(a)(B) and 2(a)(C). The Board has carefully 
considered all comments received. The Board's response to the comments 
it received and the changes made to the rules in response to the 
comments received are discussed below.
Background
Project History
1. Importance and Potential Benefits of Increased Information About 
Audit Firms and Engagements
    With the passage of the Sarbanes-Oxley Act of 2002 (``Sarbanes-
Oxley'') and the establishment of the PCAOB, Congress acknowledged and 
re-emphasized the auditor's important gatekeeping role.\6\ Reflecting 
that importance, the Board believes requiring audit firms to provide 
additional information about the firm and the engagements it performs 
will advance investor protection and promote the public interest by 
enabling investors to make better-informed decisions. As discussed in 
more detail below, the Board has also heard from investors and other 
stakeholders that they believe such information will be beneficial.
---------------------------------------------------------------------------

    \6\ See Section 101(a) of Sarbanes-Oxley, 15 U.S.C. 7211(a); 
Senate Report No. 107-205, at 5-6 (July 3, 2002).
---------------------------------------------------------------------------

    Sarbanes-Oxley also mandated new exchange requirements regarding 
the responsibilities of audit committees of listed companies, including 
requiring that audit committees be charged with responsibility for the 
appointment, compensation, and oversight of the auditor.\7\ The Board 
believes that making information available to audit committees 
regarding both the specific audit and auditor they oversee and the 
audits and auditors of their peer companies will assist them in 
carrying out this statutory mandate.
---------------------------------------------------------------------------

    \7\ See Securities Exchange Act of 1934, Section 10A(m)(2), 15 
U.S.C. 78j-1(m)(2).
---------------------------------------------------------------------------

    Over the years, the Board has received significant input on the 
importance and potential benefits to stakeholders of additional 
information about audits and auditors. The key elements of that input 
are summarized below.
i. ACAP Recommendations
    In 2007, the U.S. Treasury constituted the ACAP to consider and 
develop recommendations relating to the sustainability of the auditing 
profession.\8\ On October 6, 2008, ACAP published a report detailing 
recommendations intended to enhance the sustainability of a strong and 
vibrant public company auditing profession.\9\ One of the ACAP 
recommendations was that the PCAOB, in consultation with auditors, 
investors, public companies, audit committees, boards of directors, 
academics, and others, ``determine the feasibility of developing key 
indicators of audit quality and effectiveness and requiring auditing 
firms to publicly disclose those indicators'' \10\ and, assuming that 
development and disclosure of indicators of audit quality are feasible, 
that the PCAOB be required to monitor these indicators.

---------------------------------------------------------------------------

ii. 2013 and 2017 PCAOB Investor Advisory Group Recommendations
    At its October 2013 IAG Meeting,\11\ the IAG working group on AQIs 
made recommendations for the PCAOB to prescribe informative, forward-
looking disclosures and indicators intended to measure the quality of 
audits and enhance auditor accountability. They emphasized that 
investors and audit committees generally care more about the quality 
and credibility of audit work on specific engagements--the companies in 
which they have invested or were considering investing, or the company 
on whose board of directors they served--rather than firms' more 
general efforts to improve quality. Accordingly, in addition to 
disclosures and metrics to be reported at the firm level, they also 
recommended disclosures and metrics to be reported at the engagement 
level.
---------------------------------------------------------------------------

    \11\ See Oct. 2013 IAG meeting and presentations, Report from 
the Working Group: Audit Quality Indicators, available at IAG 
Meeting Archive, <a href="https://pcaobus.org/news-events/events/event-details/pcaob-investor-advisory-group-meeting_758">https://pcaobus.org/news-events/events/event-details/pcaob-investor-advisory-group-meeting_758</a>.
---------------------------------------------------------------------------

    At the October 2017 IAG meeting, an IAG working group discussed 
three topics: (i) why audit quality and AQIs matter to investors, (ii) 
the PCAOB's authority and efforts to date to enact AQIs, and (iii) 
audit quality initiatives in other jurisdictions.\12\ The 2017 working 
group also endorsed the 2013 AQI working group's recommendations.
---------------------------------------------------------------------------

    \12\ See Oct. 2017 IAG meeting and presentation, available at 
IAG Meeting Archive, <a href="https://pcaobus.org/news-events/events/event-details/pcaob-investor-advisory-group-meeting_1085">https://pcaobus.org/news-events/events/event-details/pcaob-investor-advisory-group-meeting_1085</a>.
---------------------------------------------------------------------------

    The recommendations provided by the 2013 and 2017 IAG working 
groups are reflected in many of the metrics the Board adopted.
2. PCAOB Initiatives
    This section provides further background and expands on the history 
of PCAOB activities related to providing additional information about 
audit firms and audits, including firm and engagement metrics.
i. 2015 AQI Concept Release
    In July 2015, the PCAOB issued the Concept Release and sought 
comment on 28 potential indicators. The indicators were organized into 
three groups:
    <bullet> Audit professionals--Measures dealing with the 
availability, competence, and focus of those performing the audit.
    <bullet> Audit process--Measures related to an audit firm's tone at 
the top and leadership, incentives, independence, attention to 
infrastructure, and record of monitoring and remediation.
    <bullet> Audit results--Financial statements, internal control, 
going concern, communications between auditors and audit committees, 
and enforcement and litigation.
    The Concept Release discussed (i) the nature of the potential 
indicators and potential calculations, (ii) the usefulness of the 
indicators, (iii) suggestions for other indicators, (iv) potential 
users of the indicators, and (v) the approach to implementation. In 
response to the Concept Release, the PCAOB received 50 comment letters.
    Most commenters expressed support for the general idea that AQIs 
may be

[[Page 99972]]

useful.\13\ However, commenter views varied widely. Comments from firms 
and firm-related groups suggested that no standard group of indicators 
could advance a person's understanding of audit quality. These 
commenters suggested that AQIs should be voluntary, should be reported 
to audit committees through two-way discussions to provide context for 
the indicators, or should be required only at the firm level. Investors 
and investor-related groups recommended that indicators should be made 
public as they could be used to stimulate competition based on quality 
among audit firms, remedy the deficiency of information about audits, 
and give shareholders meaningful information to help them in voting on 
auditor selection. Some commenters suggested that engagement-level 
metrics are more useful than firm-level metrics. One commenter 
suggested that promoting competition around an implied variability in 
audit quality may not always be appropriate and in the public interest 
because audit quality should be nonnegotiable and a fundamental goal 
for all audits. Another commenter suggested that it was critical to 
define what AQIs do and do not represent so that they are used 
appropriately.

ii. PCAOB Rulemakings To Increase Audit Transparency: Identification of 
the Engagement Partner and Other Audit Participants on Form AP and 
Auditor Communication of Critical Audit Matters
    In 2015, the PCAOB adopted rules requiring information on Form AP, 
Auditor Reporting of Certain Audit Participants, regarding the 
engagement partner and other accounting firms that participate in 
audits of issuers.\14\ The rulemaking was initially in response to the 
ACAP recommendation that the engagement partner should be required to 
sign the audit report.\15\ As the rulemaking evolved, it also took 
account of stakeholder input, including IAG recommendations to identify 
the engagement partner and the firms, other than the firm signing the 
audit report, that participate in audits.
---------------------------------------------------------------------------

    \14\ See PCAOB Rule 3211.
    \15\ See ACAP Final Report, at VII:19.
---------------------------------------------------------------------------

    The Board's intention was to make available information about the 
engagement partner and other firms that participated in the audit, 
saying that such information, even if not useful in every instance or 
meaningful to every investor, would make an overall contribution to the 
information available to investors in making voting and investment 
decisions. The Board also asserted that increased transparency should 
promote increased accountability in the audit process. The Form AP 
reporting requirements became effective in 2017, and the data gathered 
via Form AP has many users; the Form AP data set is frequently searched 
through AuditorSearch, the PCAOB's online search tool, as well as 
downloaded by users performing more detailed analyses.\16\
---------------------------------------------------------------------------

    \16\ See below.
---------------------------------------------------------------------------

    In 2017, the PCAOB adopted AS 3101, The Auditor's Report on an 
Audit of Financial Statements When the Auditor Expresses an Unqualified 
Opinion, which includes requirements regarding the disclosure of 
auditor tenure and auditor determination and communication of 
``critical audit matters.'' \17\ This project was also initiated in 
response to ACAP's recommendation that the PCAOB undertake a standard-
setting initiative to consider improvements to the auditor's standard 
reporting model.\18\ The rulemaking explored potential ways to increase 
the transparency and relevance of the auditor's report, including by 
requiring expanded auditor reporting regarding the audit and the 
company's financial statements.\19\ In the adopting release, the Board 
noted ACAP's statement that the complexity of financial reporting 
supports improving the content of the auditor's report beyond the then-
current pass/fail model to include a more relevant discussion about the 
audit of the financial statements.
---------------------------------------------------------------------------

    \17\ See AS 3101.11-.16.
    \18\ See ACAP Final Report, at VII:13.
    \19\ See Concept Release on Possible Revisions to PCAOB 
Standards Related to Reports on Audited Financial Statements and 
Related Amendments to PCAOB Standards; Notice of Roundtable (June.

---------------------------------------------------------------------------

    After multiple rounds of Board releases and stakeholder input, the 
requirements took effect in 2019 and 2020.
iii. Recent PCAOB Standard-Setting and Rulemaking Activities
    At the November 2022 Standards and Emerging Issues Advisory Group 
(SEIAG) and the October 2022 and 2023 IAG meetings, several members 
continued to urge the Board to take action on firm and engagement 
metrics. Other members stated that some firms already publish similar 
metrics through transparency reports and audit quality reports. Some 
members of the IAG and SEIAG have requested increased information at 
the firm and engagement levels through easily accessible and quantified 
metrics, potentially with accompanying context provided by the 
auditors.\20\
---------------------------------------------------------------------------

    \20\ See Nov. 2022 SEIAG meeting, available at <a href="https://pcaobus.org/news-events/events/event-details/pcaob-standards-and-emerging-issues-advisory-group-meeting-2022">https://pcaobus.org/news-events/events/event-details/pcaob-standards-and-emerging-issues-advisory-group-meeting-2022</a>.

---------------------------------------------------------------------------

    In response to the Board's request for comment on the draft 2022-
2026 Strategic Plan, some commenters encouraged the Board to continue 
to consider this topic.\21\ Additionally, in a January 2023 comment 
letter on the PCAOB's proposed quality control standard, members of the 
IAG advocated for ``a minimum requirement of eight indicators.'' \22\ 
These eight indicators were (i) staffing leverage; (ii) partner 
workload; (iii) manager and staff workload; (iv) audit hours and risk 
areas; (v) quality ratings and compensation; (vi) audit fees, effort, 
and client risk; (vii) audit firm's internal quality review results; 
and (viii) PCAOB inspection results.

Amendments to PCAOB Standards, Rules, and Forms, PCAOB Rel. No. 
2022-006 (Nov. 18, 2022). The comment letters received in response 
to the proposal are available on the Board's website in Docket 046. 
See comment letter from members of the IAG, available at <a href="https://assets.pcaobus.org/pcaob-dev/docs/defaultsource/rulemaking/docket046/4_iag.pdf?sfvrsn=1941e7c0_4">https://assets.pcaobus.org/pcaob-dev/docs/defaultsource/rulemaking/docket046/4_iag.pdf?sfvrsn=1941e7c0_4</a>.
---------------------------------------------------------------------------

a. QC 1000: Requirements
    The Board adopted a new quality control standard for firms, QC 
1000, A Firm's System of Quality Control (``QC 1000''),\23\ which 
contains provisions that are relevant to firm reporting of firm- and 
engagement-level metrics. QC 1000 will become effective in December 
2025.
---------------------------------------------------------------------------

    \23\ See A Firm's System of Quality Control and Other Amendments 
to PCAOB Standards, Rules, and Forms, PCAOB Rel. No. 2024-005 (May 
13, 2024) (``QC Adopting Release'').
---------------------------------------------------------------------------

(1) Public Communication of Firm-Level or Engagement-Level Information
    QC 1000 includes a quality objective that, if a firm communicates 
firm-level or engagement-level information with respect to the firm's 
audit practice, firm personnel, or engagements, such as firm or 
engagement metrics, to external parties, such information is accurate 
and not misleading and, with respect to any such metrics that are 
communicated

[[Page 99973]]

in writing, the communication explains in reasonable detail how the 
metrics were determined and, if applicable, how the method of 
determining them changed since the metrics were last communicated.\24\ 
(With respect to metrics reported on Form FM and Form AP, the form 
itself provides the required explanation.) The final firm and 
engagement metrics include reporting elements that focus on the firm's 
responsibility to produce and report information that is accurate and 
not misleading, for example, an optional narrative to accompany the 
metrics. This element is discussed further below.
---------------------------------------------------------------------------

    \24\ QC 1000.53e.
---------------------------------------------------------------------------

(2) Use of Metrics in Monitoring the Firm's QC System
    Under QC 1000, in determining the nature, timing, and extent of QC 
system-level monitoring activities, the firm is required to take into 
account any metrics that the firm may use in its QC system.\25\ QC 1000 
does not require the use of any specific metrics; firms have the 
ability both to develop metrics on their own and to use any or all of 
the metrics required to be reported under Rule 2203C and Rule 3211 in 
their QC system, but that is not required. The Board believes these 
metrics would provide information that could be used in the firm's 
system of quality control. However, not all firms may find all metrics 
useful in operating or monitoring their QC system, and the Board is not 
mandating their use in connection with monitoring a firm's QC system at 
this time.
---------------------------------------------------------------------------

    \25\ QC 1000.65c.
---------------------------------------------------------------------------

b. Firm Reporting
    Concurrently with this rulemaking, the Board adopted certain 
updates to its annual and special reporting requirements to facilitate 
the disclosure of more complete, standardized, and timely information 
regarding audit firms. Among other new requirements, the updates will 
(i) require firms to disclose additional information on Form 2 about 
their fees, leadership and governance structure, and network 
arrangements; (ii) require, in connection with QC 1000, a one-time 
update to the statement on a firm's quality control policies and 
procedures on a new Form QCPP; and (iii) expand the scope of special 
reporting to include events that pose a material risk, or represent a 
material change, to the firm's organization, operations, liquidity or 
financial resources, in such a manner that it will affect the provision 
of audit services, as well as new cybersecurity reporting 
requirements.\26\
---------------------------------------------------------------------------

    \26\ See PCAOB Rel. No. 2024-013.
---------------------------------------------------------------------------

c. Proposed Firm and Engagement Metrics
    In April 2024, the Board proposed amendments to the PCAOB's rules 
and reporting forms to require the reporting of specified firm-level 
metrics on new Form FM, Firm Metrics, and specified engagement-level 
metrics on an amended and renamed Form AP, Audit Participants and 
Metrics. In the Board's proposal, it proposed a set of firm-level and 
engagement-level metrics across 11 areas to be publicly reported for 
the firms that serve as lead auditor for at least one accelerated filer 
or large accelerated filer.
    The Board received over 45 comment letters on the proposal.\27\ 
Commenters included investor-related groups, firms, firm-related 
groups, academics, and others.
---------------------------------------------------------------------------

    \27\ The comment letters received on the proposal are available 
at <a href="https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-041/comment-letters">https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-041/comment-letters</a>.
---------------------------------------------------------------------------

    Some commenters expressed concerns about the speed of rulemaking by 
the Board. Some commenters asked the PCAOB for more than 60 days to 
respond to the proposal, citing overlapping comment proposal periods, 
the duration of comment periods, the length and complexity of various 
proposals, and overlapping SEC 19b-4 filing comment periods. On the 
other hand, a commenter urged the Board not to delay this rulemaking 
because investors need a relatively standardized data set to analyze 
and compare over time and across companies. The Board believes that 60 
days was a sufficient period for commenting on the proposal. Despite 
that, the Board considered comment letters that were submitted after 
the 60-day period closed. The Board received robust comments on the 
proposal, which informed the final metrics or final rules.\28\ These 
comments are addressed throughout this Exhibit 1 and in the Board's 
adopting release (Exhibit 3).

Release (including comments received) and the PCAOB IAG 
recommendations.
---------------------------------------------------------------------------

3. Overview of Existing Requirements
    Under current PCAOB rules and standards, certain information about 
PCAOB-registered firms is already made available to investors, audit 
committees, and other stakeholders. The disclosure of firm- and 
engagement-level metrics would supplement this information. This 
section discusses the key PCAOB standards and rules that require 
certain firm- and engagement-level information to be provided to 
various stakeholders.
i. Available Information Related to Firms
    PCAOB rules require firms to file Form 2 (Annual Report Form) to 
report basic information about the firm and its audit practice and Form 
3 (Special Reporting Form) after the occurrence of certain events.\29\ 
In addition, the PCAOB makes portions of inspection reports publicly 
available for firms that are subject to annual or triennial PCAOB 
inspections.
---------------------------------------------------------------------------

    \29\ PCAOB Rule 2200, Annual Report; PCAOB Rule 2201, Time for 
Filing of Annual Report; PCAOB Rule 2203, Special Reports; 
Instructions to Form 2, available at <a href="https://pcaobus.org/about/rules-rulemaking/rules/form_2">https://pcaobus.org/about/rules-rulemaking/rules/form_2</a>; Instructions to Form 3, available at 
<a href="https://pcaobus.org/about/rules-rulemaking/rules/form_3">https://pcaobus.org/about/rules-rulemaking/rules/form_3</a>. Information 
reported on Forms 2 and 3 is publicly available unless a firm 
requests confidential treatment.
---------------------------------------------------------------------------

a. Form 2 and Form 3
    As required by Section 102(d) of Sarbanes-Oxley and PCAOB Rule 
2200, each year registered firms must file an annual report with the 
Board. Under PCAOB rules, firms must do so by filing Form 2. The annual 
reporting period runs from April 1 to March 31, and the due date for 
filing is June 30.\30\ In addition to basic identifying information 
about the firm,\31\ firms report on Form 2 general information about 
their audit practices and other business relationships. Information 
required to be provided on Form 2 includes:
---------------------------------------------------------------------------

    \30\ PCAOB Rule 2201; General Instructions 3-4 to Form 2 
(registered public accounting firm that has its application for 
registration approved by the Board in the period between and 
including April 1 and June 30 of any year not required to file an 
annual report in that year).
    \31\ Instructions to Form 2, Item 1.1.
---------------------------------------------------------------------------

    <bullet> Whether the firm issued audit reports for issuers, 
brokers, or dealers or played a substantial role in issuer or broker-
dealer audits; \32\
---------------------------------------------------------------------------

    \32\ Id., Item 3.1. The Board's release uses the terms 
``issuer,'' ``broker,'' and ``dealer'' as those terms are defined 
under Sections 2(a)(7) and 110(3)-(4) of Sarbanes-Oxley. 15 U.S.C. 
7201(a)(7), 7220(3)-(4). See also paragraphs (b)(iii), (d)(iii), and 
(i)(iii) of PCAOB Rule 1001, Definitions of Terms Employed in Rules. 
Entities that are brokers or dealers or both are sometimes referred 
to as ``broker-dealers.''
---------------------------------------------------------------------------

    <bullet> Percentage of total fees billed to issuers for audit 
services, other accounting services, tax services, and non-audit 
services; \33\
---------------------------------------------------------------------------

    \33\ Instructions to Form 2, Item 3.2.
---------------------------------------------------------------------------

    <bullet> For each issuer or broker-dealer for which the firm issued 
an audit report, the issuer's or broker-dealer's name, its Central 
Index Key (CIK) number and Central Registration Depository (CRD) number 
(if any), and the date of the audit report, as well as the total number

[[Page 99974]]

of firm personnel who exercised authority to sign the firm's name to an 
audit report for an issuer or broker-dealer during the reporting 
period; \34\
---------------------------------------------------------------------------

    \34\ Id., Items 4.1, 4.3.
---------------------------------------------------------------------------

    <bullet> Physical address (and, if different, mailing address) of 
each firm office; \35\

similar arrangements involving certain activities related to audit or 
accounting services (including use of name in connection with audit 
services, marketing of audit services, and employment or lease of 
personnel to perform audit services), and the entities with which the 
firm has those relationships; \36\
---------------------------------------------------------------------------

    \36\ Id., Item 5.2.
---------------------------------------------------------------------------

    <bullet> Total number of accountants, certified public accountants, 
and personnel; \37\
---------------------------------------------------------------------------

    \37\ Id., Item 6.1.
---------------------------------------------------------------------------

    <bullet> Relationships with certain individuals and entities with 
disciplinary or other histories (if not previously identified); \38\

---------------------------------------------------------------------------

    <bullet> Acquisitions of another public accounting firm or a 
substantial portion of another firm's personnel.\39\
---------------------------------------------------------------------------

    \39\ Id., Item 8.1
---------------------------------------------------------------------------

    In addition to annual reporting on Form 2, firms are required to 
file Form 3 within 30 days after the occurrence of certain events, such 
as when the firm's legal name has changed while otherwise remaining the 
same legal entity, the firm has withdrawn an audit report on the 
financial statements of an issuer or has resigned, declined to stand 
for re-appointment, or been dismissed from an audit engagement as 
principal auditor, and the issuer has failed to comply with applicable 
Form 8-K reporting requirements for such events.\40\

    \40\ General Instruction 3 to Form 3; Instructions to Form 3, 
Items 2.17, 2.1, 2.1-C, 3.1, 3.2.
---------------------------------------------------------------------------

b. Firm Inspection Reports
    Sarbanes-Oxley authorizes the PCAOB to inspect firms for the 
purpose of assessing compliance with certain laws, rules, and 
professional standards in connection with a firm's audit work for 
issuers, brokers, and dealers. Firms that issue audit reports for more 
than 100 issuers per year are inspected annually. Firms that issue 100 
or fewer audit reports per year for issuers are generally inspected at 
least once every three years. The Board also inspects firms that play a 
substantial role in audits of issuers. Many firms registered with the 
Board perform no audit work for issuers or broker-dealers,\41\ or only 
participate in audits below the level of a substantial role, and the 
Board has not historically inspected those firms. The PCAOB provides 
each inspected firm with a report summarizing any deficiencies 
identified through the inspections process. Portions of these 
inspection reports are publicly available on the PCAOB's website.\42\ 
Recently the PCAOB introduced enhanced search tools that enable 
investors and others to better access and understand data from PCAOB 
inspection reports.\43\
---------------------------------------------------------------------------

    \41\ See QC Adopting Release at 54.
    \42\ See <a href="https://pcaobus.org/oversight/inspections">https://pcaobus.org/oversight/inspections</a> for 
inspection reports, basics of inspections, and inspection 
procedures. Sarbanes-Oxley provides that no portions of an 
inspection report that deal with criticisms of or potential defects 
in the quality control systems of the firm shall be made public if 
those criticisms or defects are addressed by the firm, to the 
satisfaction of the Board, no later than 12 months after the 
issuance of the inspection report. See Sarbanes-Oxley Section 
104(g)(2). Full (expanded) inspection reports are publicly available 
on the PCAOB's website when a firm fails to satisfactorily remediate 
within 12 months.
    \43\ See <a href="https://pcaobus.org/news-events/news-releases/news-release-detail/pcaob-launches-new-online-tools-to-help-users-find-and-compare-inspection-report-data">https://pcaobus.org/news-events/news-releases/news-release-detail/pcaob-launches-new-online-tools-to-help-users-find-and-compare-inspection-report-data</a> for a summary of the 
enhancements, including six new search filters, including Part I.A 
deficiency rate, to help users analyze and compare more than 3,700 
inspection reports.
---------------------------------------------------------------------------

ii. Available Information Related to Issuer Engagements
a. Auditor's Communications With Audit Committees
    Investors and other financial statement users are the beneficiaries 
of the audit. Audit committees protect the interests of investors by 
assisting the board of directors in fulfilling its responsibility to 
oversee the integrity of the company's accounting and financial 
reporting processes, including the audit of the company's financial 
statements--and in carrying out that duty, they also benefit other 
financial statement users. To support the audit committee in this 
crucial role, PCAOB standards and rules and SEC rules require auditors 
to provide certain firm- and engagement-level information to audit 
committees.\44\ AS 1301, Communications with Audit Committees, requires 
various communications to facilitate the audit committee's financial 
reporting oversight.\45\ Among other things, AS 1301 requires the 
auditor to communicate: (i) significant risks; \46\ (ii) critical 
accounting policies and practices, critical accounting estimates, and 
significant unusual transactions; \47\ (iii) the auditor's evaluation 
of the quality of the company's financial reporting; \48\ and (iv) 
other matters that are significant to the oversight of the company's 
financial reporting process.\49\ In addition, other PCAOB standards and 
rules and SEC rules independently require certain audit committee 
communications.\50\
---------------------------------------------------------------------------

    \44\ See Auditing Standard No. 16, Communications with Audit 
Committees; Related Amendments to PCAOB Standards; and Transitional 
Amendments to AU Sec. 380, PCAOB Rel. No. 2012-004 (Aug. 15, 2012),

Concerning Independence.
---------------------------------------------------------------------------

b. Auditor's Public Communications of Certain Information
    AS 3101 and Rule 3211 require firms to publicly disclose certain 
engagement-specific information in the auditor's report and on Form AP. 
In addition to specifying the requirements for an unqualified opinion 
on the financial statements, AS 3101 requires the auditor's report to 
describe (i) critical audit matters, which inform investors and other 
financial statement users of matters arising from the audit that 
required especially challenging, subjective, or complex auditor 
judgment; and (ii) how the auditor addressed those matters. AS 3101 
further requires the auditor's report to include a statement disclosing 
the year in which the auditor began serving consecutively as the 
company's auditor. Other standards require additional information to be 
included in the auditor's report, including AS 2415, Consideration of 
an Entity's Ability to Continue as a Going Concern, which requires an 
explanatory paragraph when the auditor concludes that there is 
substantial doubt about the entity's ability to continue as a going 
concern for a reasonable period of time.\51\
---------------------------------------------------------------------------

    \51\ See AS 2415.12.
---------------------------------------------------------------------------

    PCAOB Rule 3211 requires auditors to file Form AP, which, among 
other things, provides information to investors and other financial 
statement users about the engagement partner and other accounting firms 
participating in the audit of issuers. Disclosures on Form AP provide 
increased transparency about certain audit participants. The key 
provisions include annual disclosures of (a) the name of the engagement 
partner and (b) the name and extent of participation of other 
accounting firms in the audit.\52\
---------------------------------------------------------------------------

    \52\ See Instructions to Form AP. Form AP requires different 
disclosures regarding other accounting firms that participate in an 
audit depending on their level of participation. For other 
accounting firms with individually 5% or greater participation in 
the audit, the Form AP filer must disclose the legal name of the 
other accounting firm, the city and state (or, if outside the United 
States, the city and country) of that firm's headquarters, and the 
percentage of total audit hours (either as a single number or within 
a range provided on the form) attributable to each other accounting 
firm. For other accounting firms with individually less than 5% 
participation, the filer must disclose the total number of such 
other accounting firms and the aggregate percentage (either as a 
single number or within a range provided on the form) of total audit 
hours for all such firms.

---------------------------------------------------------------------------

[[Page 99975]]

    The PCAOB makes the Form AP data set available on AuditorSearch, by 
which users can conduct live searches or download the entire data set 
in a searchable, machine-readable format.\53\ Using this data, a user 
can determine, for example, the changes in engagement partner for any 
given issuer or obtain a list of all issuers for which an engagement 
partner is responsible. After identifying an engagement partner, a user 
can then compile information from other sources, including information 
about whether the partner is associated with restatements of financial 
statements, has been subject to public disciplinary proceedings, or has 
experience as an engagement partner for issuers of a particular size or 
in a particular industry. Similarly, starting from the Form AP data 
set, users may perform further research on the other accounting firms 
that participate in an audit, such as whether those firms are 
registered with the PCAOB, whether they have any publicly available 
disciplinary history, whether they have been inspected, and, if so, the 
results of those inspections.
---------------------------------------------------------------------------

    \53\ See AuditorSearch, available at <a href="https://pcaobus.org/resources/auditorsearch">https://pcaobus.org/resources/auditorsearch</a>.
---------------------------------------------------------------------------

4. Voluntary Firm Reporting
    Since the Concept Release, many of the audit firms that issue audit 
reports for more than 100 issuers and audit the majority of the market 
capitalization for issuers have been publicly disclosing certain firm-
level information discussed in the Concept Release through their audit 
quality reports, transparency reports, or other published reports. A 
firm-related group has published a framework to assist its members in 
these efforts.'' \54\ Many firms may also be developing and monitoring 
certain firm and engagement metrics to be used internally by the firm. 
In 2023, the same firm-related group published a summary analysis of 
the most recent audit quality reports issued by the eight firms 
represented on the group's governing board.\55\ The report indicated 
that firms were reporting similar firm-level quantitative metrics 
related to several areas, including audit firm inspections; training; 
use of auditor's specialists; audit report reissuances and financial 
statement restatements; measures of experience, such as tenure with the 
firm; and personnel turnover. The report further noted that some firms 
disclosed qualitative as well as quantitative information, including 
information relating to audit methodology and execution, people and 
firm culture, quality management and inspections, and technology and 
innovation.

2023). The framework provides that metrics ``may provide those 
overseeing the audit and other stakeholders with information and 
additional transparency into the firm's systems and processes that 
impact audit quality. However, the CAQ believes that a combination 
of metrics--taken as a whole and supplemented with robust 
discussion--may provide those overseeing the audit and other 
stakeholders with information and additional transparency into the 
firm''s systems and processes that impact audit quality.'' Id. at 4.

(Mar. 2023), available at <a href="https://www.thecaq.org/aqr-analysis-yir">https://www.thecaq.org/aqr-analysis-yir</a> 
(``CAQ Report''). The eight firms on the CAQ's governing board are

Grant Thornton LLP, KPMG LLP, PricewaterhouseCoopers LLP, and RSM US

---------------------------------------------------------------------------

    The Board has observed the firms that report firm-level metrics 
generally do not report engagement-level metrics.\56\ Where firm-level 
metrics are reported, the firms report different metrics, calculated in 
different ways, and using different definitions, thereby preventing 
users from making comparisons across firms.
---------------------------------------------------------------------------

    \56\ In connection with the Nov. 2022 SEIAG meeting, the Board 
staff researched various reports issued during the prior three years 
by the top 20 accounting firms (by 2022 revenue) and identified nine 
firms that disclosed firm-level metrics. See Firm and Engagement 
Performance Metrics Briefing Paper and Related Attachments from Nov. 
2022 SEIAG meeting, available at <a href="https://pcaobus.org/news-events/events/event-details/pcaob-standards-and-emerging-issues-advisory-group-meeting-2022">https://pcaobus.org/news-events/events/event-details/pcaob-standards-and-emerging-issues-advisory-group-meeting-2022</a>. For each firm-level metric reported by those 
nine firms, the PCAOB staff included examples of how firms 
calculated the metric as well as the number of firms reporting that 
metric.
---------------------------------------------------------------------------

    One commenter on the Concept Release stated that many firms are 
using the 28 AQIs identified in the Concept Release at some level to 
(i) manage the firm and (ii) manage the quality of audits at the office 
level and at the engagement level. Another commenter specifically 
indicated that its audit committee reviewed the engagement-level AQIs 
identified in the Concept Release that were provided by their auditor.
    One commenter on the proposal asserted that the voluntary reporting 
firms already do through transparency and audit quality reports 
includes firm-level metrics, as well as explanations of how they are 
calculated, including changes in the calculation that could affect 
comparability, as well as context necessary for understanding the 
metrics, and would be preferable to the mandatory metrics that the 
Board proposed. On the other hand, an investor-related group presented 
an analysis of firm transparency and audit quality reports, finding 
that the measures used in transparency reports and audit quality 
reports by different firms are not consistent or comparable across 
firms in their computations, presentation and inclusion, and are not 
provided at the engagement level, which the commenter believes is the 
level at which they would be most useful. This commenter stated that 
having both firm- and engagement-level metrics enhances the metrics' 
usefulness because it provides broader context for understanding at 
both levels.
Actions in Other Jurisdictions
    Some jurisdictions outside the United States have moved forward 
with mandatory or voluntary initiatives related to the monitoring and 
disclosure of metrics. In May 2022, Accountancy Europe published a 
factsheet about recent related initiatives in Europe and elsewhere.\57\ 
The Accountancy Europe Report described initiatives conducted in 10 
countries (including the United Kingdom (U.K.), South Africa and 
Canada) by various organizations, including audit oversight bodies 
(including the U.K.'s Financial Reporting Council (FRC), Portugal's 
Securities Market Commission (CMVM), South Africa's Independent 
Regulatory Board for Auditors (IRBA), and the Canadian Public 
Accountability Board (CPAB)),\58\ professional organizations,\59\ a 
group of independent experts,\60\ and the CAQ. Additionally, the FRC in 
the U.K. issued a consultation document and a feedback statement in 
2022 on publishing AQIs for the largest U.K. audit firms,\61\ the IRBA 
in South Africa

[[Page 99976]]

requested firms auditing listed companies to submit AQI-related 
information to the IRBA,\62\ and the CPAB launched an exploratory pilot 
project to solicit feedback on AQIs' usefulness in support of broader 
national and international discussions.\63\ The primary users of the 
metrics from these initiatives were audit committees, oversight bodies, 
and professional organizations. Although many of the metrics in these 
initiatives were nonpublic, public reporting was encouraged or 
anticipated in the future for half of the initiatives.\64\ The 
Accountancy Europe Report suggested that several factors should be 
considered when selecting, evaluating, and reporting metrics and 
recommended that a combination of metrics would provide ``profound 
insight into audit quality.''

    In January 2023, Accountancy Europe published a position paper.\65\ 
The position paper defined key concepts related to audit quality, 
presented considerations for developing AQIs, and explained what, in 
its view, can and cannot be achieved by reporting such indicators (for 
example, the paper pointed out that all metrics have limitations, that 
metrics are not a proxy for financial reporting quality, and that user 
expectations should be managed to make them aware that metrics do not 
provide definitive results). The paper stated as part of its conclusion 
that ``[AQIs] should not be considered as an end in themselves but 
could be a useful tool to drive audit quality'' and reiterated that a 
combination of metrics would provide insight into audit quality.

---------------------------------------------------------------------------

    Some commenters noted that initiatives in other jurisdictions do 
not currently require public disclosure. Others suggested that the 
requirements that the Board proposed were more onerous than other 
jurisdictions and may cause reporting of different calculations for 
similar metrics in different jurisdictions. One commenter provided 
examples in other jurisdictions including providing optional guidance, 
allowing engagement-level metrics to be shared confidentially with 
audited entities, and allowing for voluntary adoption. Another 
commenter expressed its belief that the Board is attempting to justify 
individual metrics based on certain jurisdictions' use but have not 
fully considered the context in how they are being used or the process 
that has been undertaken in those jurisdictions. An additional 
commenter stated that the comparability problem between jurisdictions 
could be solved by allowing firms to voluntarily disclose the metrics 
as defined. One commenter expressed the hope that audit regulators 
globally will seek to align requirements relating to the reporting of 
metrics.
    While other jurisdictions have not historically required public 
reporting, the U.K. FRC has announced that it will begin to require 
public reporting in 2025.\66\
---------------------------------------------------------------------------

    \66\ See <a href="https://www.frc.org.uk/consultations/aqis-consultation">https://www.frc.org.uk/consultations/aqis-consultation</a>. 
In June 2025, the FRC is requiring firms that audit 20 or more 
public interest entities to publicly report ten firm-level metrics 
across five areas. These areas include (i) Performance monitoring 
and remediation, (ii) Quality monitoring, (iii) Resource planning 
and people management, (iv) Information and communication, and (v) 
Governance and leadership.
---------------------------------------------------------------------------

    The Board considered the actions taken in other jurisdictions in 
developing the final metrics. While substantially all the final metrics 
are the same as, or similar to, metrics used in some other 
jurisdictions, the Board acknowledges that no other jurisdiction has 
embraced either the full set of metrics or the public reporting 
requirements the Board has adopted. However, the Board's objective in 
understanding actions in other jurisdictions was not to conform to what 
they have done but rather to consider those actions in the context of 
the Board's own rulemaking, which is addressed further below. The Board 
believes that its approach to evaluating and determining which metrics 
should be disclosed is appropriate in light of its statutory investor-
protection mission.
Discussion of the Final Rules
Overview
    As noted above, the Board considered ways to measure audit firm and 
audit performance, primarily with a view to providing information that 
investors can use in making decisions regarding their investments, such 
as ratifying the selection of the auditor and voting for members of the 
board of directors, including directors who serve on the audit 
committee. The Board also believes that firm and engagement metrics 
will benefit other stakeholders. For audit committees, metrics will 
provide additional context, including consistent comparative 
information that is not currently available, that can be used when 
deciding whether to select or retain a firm and when overseeing the 
auditor's performance. For audit firms, metrics will provide 
standardized information about themselves and their peers that can be 
used in designing, implementing, monitoring, and remediating their 
systems of quality control. The Board will also benefit from having 
additional tools to use in its inspections program and standard-setting 
initiatives.
    This rulemaking addresses the need for information by requiring 
consistent, comparable disclosures that the Board believes will provide 
insight into aspects of the firm and the engagement team conducting the 
audit, including information relating to workloads, retention, 
allocation of audit hours, experience, and restatements.
1. Purpose of the Metrics
    Investors and other stakeholders lack information that is available 
to company management. The federal securities laws seek to reduce this 
information asymmetry through various disclosure, internal control, and 
other requirements, including requirements for public companies to 
prepare and disclose financial statements accompanied by audit reports 
issued by an independent public accounting firm. Investors and other 
stakeholders also lack information available to the auditor and cannot 
observe the auditor's work or other aspects of a public company audit. 
Instead, they must rely on the audit committee, which is charged with 
overseeing the external auditor, and on other available public 
information, such as the reputation of the firm issuing the audit 
report or the name of the engagement partner. These difficulties in 
evaluating the audit and the auditor may lead to reduced accountability 
for auditors and an inefficient allocation of audit effort. Such 
allocations allow audit risk to remain insufficiently evaluated, 
ultimately risking suboptimal investment decisions, hampering the 
efficient functioning of the audit profession, and negatively affecting 
the

[[Page 99977]]

capital markets.\67\ Furthermore, while the audit committee has more 
information regarding the specific auditor it oversees, it lacks 
insight into other audit engagements and other firms; such comparable 
information would assist the audit committee in more effectively 
selecting and monitoring the auditor.
---------------------------------------------------------------------------

    \67\ There is a long stream of research regarding the effects 
that information asymmetry about product features, such as quality, 
and disclosure have on markets. See, e.g., George A. Akerlof, The 
Market for ``Lemons'': Quality Uncertainty and the Market Mechanism, 
84 The Quarterly Journal of Economics 488 passim (1970); and Robert 
E. Verrecchia, Essays on Disclosure, 32 Journal of Accounting and 
Economics 97 (2001).
---------------------------------------------------------------------------

    Investors and other stakeholders may seek to reduce these 
information disparities by gathering additional information about the 
firm responsible for the audit and the relevant audit engagement. As 
discussed above, the PCAOB has previously sought to facilitate those 
efforts through rules and standards requiring the disclosure of such 
information. From its inception, the Board's registration and reporting 
program has yielded important information about registered firms. 
Annual updates on Form 2 include information such as the issuers 
audited by the firm, a breakdown of fees charged to issuers, and 
network affiliations, and current reporting on Form 3 discloses 
significant events such as the withdrawal of an audit report and 
certain legal actions involving the firm or its professionals. The 
Board concurrently adopted amendments to both of those reporting forms 
to mandate the disclosure of standardized and timely information by 
firms.\68\ Firms are required to disclose on Form AP the name of the 
engagement partner and certain audit participants.\69\ The Board also 
made the auditor's report more relevant and informative by, among other 
things, requiring communication of critical audit matters and the 
tenure of the auditor.\70\ The Board intends the firm and engagement 
metrics to complement these other initiatives and to add to the mix of 
information available to investors and other stakeholders when 
evaluating the auditor and the audit.\71\
---------------------------------------------------------------------------

    \68\ See PCAOB Rel. No. 2024-013.
    \69\ See PCAOB Rule 3211.
    \70\ See AS 3101.10.b, .11-.16.
    \71\ In addition to disclosures on Form AP and in the audit 
report, the Board previously required information on periodic and 
special reports to be publicly available. See Rules on Periodic 
Reporting by Registered Public Accounting Firms, PCAOB Rel. No. 
2008-004 (June 10, 2008), 28-32.
---------------------------------------------------------------------------

    The Board's oversight activities have revealed that there are 
identifiable performance differences across firms and among engagement 
teams within the same firm, including variations among firms belonging 
to global networks. The Board considered such differences when 
performing regulatory functions. For example, the Division of 
Registration and Inspections uses, among other factors, information 
about the firm and the engagement to identify audit engagements for 
risk-based selections in the Board's inspections program.
    Mandating public disclosure of firm- and engagement-level metrics 
will provide investors, audit committees, and other stakeholders with 
comparable information that is not currently available and will 
otherwise be difficult or impossible to obtain. These stakeholders will 
be able to learn about both specific engagements and specific firms and 
have a basis to compare them to other engagements and other firms. The 
firms themselves could also benefit from access to information about 
their peers, both in gaining new perspective on how their practices 
compare and in potentially gaining new opportunities for competition 
based on markers that users come to associate with quality. Required 
disclosures will facilitate development of standardized data for 
consistent comparison and analysis over time, which the Board believes 
will be more valuable than the ad hoc, individualized disclosures that 
some firms have made on a voluntary basis. Mandatory public disclosure 
will also ensure that the information will be accessible to all 
stakeholders, so that any decision-useful information can be readily 
evaluated. The Board believes this information will enable investors, 
audit committees, and other stakeholders to make better-informed 
decisions.\72\
---------------------------------------------------------------------------

    \72\ Under Section 102 of Sarbanes-Oxley, the Board may require 
registered public accounting firms to submit periodic and special 
reports containing financial or other information as is ``necessary 
or appropriate in the public interest or for the protection of 
investors.'' 15 U.S.C. 7212(d). Section 103 of Sarbanes-Oxley tasks 
the Board with adopting quality control and other standards to be 
used by registered firms ``in the preparation and issuance of audit 
reports . . . as may be necessary or appropriate in the public 
interest or for the protection of investors.'' 15 U.S.C. 7213(a)(1). 
See also 15 U.S.C. 7211(a), (c)(5), 7213(a)(2)(B). The Board 
believes the proposed metrics would further the public interest and 
would protect investors in accordance with these provisions.
---------------------------------------------------------------------------

    The Board believes the metrics will also assist the PCAOB in a 
variety of ways. Metrics will help to inform the Board's inspection 
activities, including in the selection of firms, engagements, and focus 
areas for review. For example, the final metrics could refine the 
selection models used to aid in predicting negative audit outcomes, 
enhancing the Board's risk-based inspections. They could also enrich 
the discussions the Board has with audit committee chairs as part of 
the Board's inspections process. Metrics may also inform future 
standard-setting activities by helping the Board to identify areas 
where regulatory action is needed and suggesting potential approaches. 
In addition, the Board expects metrics to enhance the PCAOB's ability 
to produce impactful research and to provide valuable information 
sources for the public, including academic research, helping to create 
new insights into the audit.
    The Board's discussion of the potential benefits of the final 
metrics in greater detail below.
2. Public Reporting of Metrics
    Many commenters on the proposal addressed the fundamental question 
of whether there was value in mandating a set of publicly reported 
metrics, expressing conflicting views. Investors and investor-related 
groups were generally supportive. Many other commenters, primarily 
firms and firm-related groups criticized the proposal. These commenters 
either supported public reporting of some firm-level metrics but not 
others while generally opposing any public reporting of engagement-
level metrics, or opposed all public reporting of metrics at both the 
firm and engagement levels.
    Among the commenters that supported the metrics proposal, several 
stressed the benefits of increased transparency for key stakeholders 
and the public overall. Several commenters generally agreed with the 
PCAOB's rationale for the metrics, including increasing competition 
among audit firms, including on the basis of audit quality; promoting 
auditor accountability, which will lead to greater audit quality; and 
providing investors with decision-useful comparable information that 
will assist them in making decisions about audit-related matters (e.g., 
ratifying the appointment of the auditor or voting for reelection of 
Board members that serve on the audit committee). Two of these 
commenters asserted that investors currently lack information to make 
an independent and informed decision regarding ratification of the 
appointment of the auditor and to hold audit committee members to 
account in the performance of their duties. In that context, one of 
these commenters pointed out that most failures to ratify the 
appointment of the auditor occur after a financial reporting failure, 
and argued that metrics would provide information allowing investors to 
make

[[Page 99978]]

an ex ante, rather than ex post, evaluation of the auditor's work.
    Two commenters particularly favored engagement-level metrics. One 
said it would enable the compilation of engagement-level data for all 
public company audit engagements within a specific office to compare 
data for competing offices within the same geographic area. In this 
commenter's view, metrics such as workload would provide great value to 
prospective employees and would improve the talent pipeline issue 
because firms' workload need to be competitive in the eyes of 
prospective employees. Another argued that engagement-level metrics are 
most useful to investors, using firm-level metrics to provide context. 
This commenter also emphasized the importance of firm-level metrics, 
which will provide context in evaluating engagement-level metrics and a 
firm's audit practice and its related system of quality control.
    Several commenters said that the benefits of metrics would likely 
evolve over time, for example, as users are able to aggregate multiple 
data points, make comparisons, and observe trends. The Board agrees and 
believes that analyzing the metrics over time, across engagements and 
across firms, in the context of known good practices and indicators of 
audit failure, will enable the PCAOB, as well as academics and users of 
the metrics, to gain a new perspective on the audit and potentially 
deeper insights into some of the drivers of audit quality.
    Many larger firms generally supported certain firm-level metrics. 
These commenters generally agreed that firm-level reporting could 
provide stakeholders with relevant information through consistent 
disclosure by all firms required to report. While some of the 
commenters raised concerns about the usefulness, comparability, and 
risk of misinterpretation of certain firm-level metrics; the risk that 
standardization of metrics limits their adaptability to change in the 
business and auditing environment; and more generally concerns that the 
costs may outweigh the benefits, commenters agreed that the proposed 
firm-level metrics are generally consistent with voluntary disclosures 
that some firms are already making in firm transparency and audit 
quality reports. A discussion of the comments made with regard to 
particular metrics is provided below.
    However, firms and firm-related groups generally opposed 
engagement-level metrics. Some questioned whether investors would use 
the metrics. Others expressed concern that publicly available metrics 
could contribute to information overload. Many said that it would not 
be possible to provide sufficient context to enable users to understand 
the metrics, even with the firm-level metrics or narrative disclosures. 
Some commenters asserted that, because the underlying circumstances of 
engagement-level metrics are not homogeneous and users would not have 
necessary context, engagement-level metrics would not be 
comparable.\73\ Others focused on the significance of qualitative 
factors such as professional judgment and the duty to exercise due 
care, including professional skepticism, saying that metrics were 
inappropriately ``one size fits all'' or not decision-useful because 
they do not capture these key concepts.
---------------------------------------------------------------------------

    \73\ Commenters listed various types of contexts that in their 
view would be necessary for proper understanding of the engagement-
level metrics, including variations across firms (e.g., differences 
in operations, structures, methodologies, and resources), the unique 
circumstances of each engagement (e.g., differences in risk areas, 
team compositions, and timelines), and the unique circumstances of 
each issuer (e.g., differences in policies and resources).
---------------------------------------------------------------------------

    Many commenters expressed concern that users would not find metrics 
meaningful and may even misunderstand them and reach inappropriate 
conclusions. Absent providing substantial context and understanding how 
stakeholders would use the metrics, in one commenter's view, investors 
may make capital allocation decisions based on a misinterpretation of a 
metric, resulting in a new element of volatility in the capital 
markets. Two commenters raised a concern that the proposal does not 
provide a tie between assessing audit quality and the proposed metrics. 
Some commenters went on to say that providing metrics in isolation 
without context and effective two-way communication would have very 
minimal, or even negative, impact on audit quality. Another commenter 
stated that most of the data points required as part of the proposal 
are currently available to the PCAOB.
    One commenter expressed concern that overemphasis on metrics could 
lead firms to focus on consistency of the metrics to avoid the 
implication of weak auditing or other potential misinterpretations, 
which in the commenter's view could lead to commoditization of the 
audit and reduce incentives to innovate the audit approach. On the 
other hand, several other commenters argued that metrics would support 
more robust competition based on quality, making the audit less of a 
commodity.
    Some commenters said that the metrics seemed particularly focused 
on larger firms or would be especially burdensome for smaller firms. 
The Board believes the final metrics call for data that will be 
relevant to and obtainable by firms regardless of size. The potential 
differential cost impacts are discussed below.
    Some commenters questioned whether public reporting of metrics 
would undermine the authority of the audit committee. For example, one 
expressed concern that there would be public pressure on the audit 
committee to appoint auditors whose metrics were perceived to be within 
some acceptable range, even if the committee was satisfied with the 
work of the current auditor. Another commenter asserted that it is not 
investors' responsibility to oversee the auditor, and raised a concern 
that public reporting of metrics could undermine confidence in audit 
committees and the PCAOB, both of which have responsibilities for 
direct oversight of audits and audit firms and have the context to 
properly understand these metrics. However, an investor-related group 
specifically disagreed with this reasoning and asserted that this 
rulemaking exhibits commitment to faithfully executing the PCAOB's 
responsibilities and working to improve audit quality and trust in the 
audit market.
    Several commenters opposed both firm- and engagement-level metrics. 
One asserted that the proposal did not provide sufficient evidence that 
public disclosure of the proposed metrics will have any meaningful 
impact on the quality of audit services. Another commenter said that 
the metrics were not grounded in or intended to have any nexus with 
audit quality, focusing instead on auditor accountability, and on that 
basis went beyond the PCAOB's remit. The commenter asserted that the 
proposed metrics would overload audit committees and investors with a 
large set of complex data that was not sought, needed, meaningful, or 
obviously usable by them, suggesting that the current voluntary 
approach should be maintained instead. Another expressed concern that 
public disclosure of the information specified in the proposals could 
do more harm than good, particularly in relation to an increase in 
litigation and reputational risk and potentially furthering the talent 
crisis in the profession. That commenter particularly questioned the 
potential value of metrics for audit committees, saying that they 
already have access to most of the information that would be mandated 
and that annual reporting would be unhelpful since evaluation of the 
auditor is a continuous process. One commenter who advocated delay and

[[Page 99979]]

further study before the Board takes further action on the metrics 
expressed skepticism that metrics would influence shareholder votes on 
ratification of the appointment of the auditor or benefit most 
investors, because metrics are only indirectly related to audit quality 
and there would not be sufficient incentive for users to engage with 
them.
    Most of the commenters who objected to public reporting of metrics 
recommended alternatives, including mandatory or voluntary 
communication with the audit committee, particularly for engagement-
level metrics. Many commenters asserted that the audit committee is the 
appropriate party to whom engagement-level metrics should be 
communicated, because the audit committee has the statutory 
responsibility to appoint, compensate, and replace the external auditor 
and is sufficiently informed to understand the context of the company, 
the audit, and the auditor. Commenters said that audit committees could 
engage in dialog with the auditor, enabling them to understand the 
metrics in the context of the specific audit, promoting accountability 
in the performance of the audit on behalf of investors. Another 
commenter asserted that providing information to, and allowing the 
assessment by, audit committees would be more likely to provide greater 
benefits to investors and the capital markets than public reporting, 
while minimizing unintended consequences (such as users reaching 
inappropriate conclusions), and would be consistent with the PCAOB's 
objective to improve audit quality. Another commenter, who questioned 
the value of metrics for most investors, said metrics had the potential 
to be quite useful for audit committees, who could use their direct 
access to the auditor to gain valuable context and would have the 
opportunity, using metrics, to communicate more about the audit process 
in their audit committee report. On the other hand, an investor-related 
group pointed out that audit committees are reliant on communications 
from the auditor regarding the company's audit issues and the quality 
of the audit; their principal tool is inquiry, not observation, which, 
in audit parlance, is the weakest form of audit evidence.
    Many commenters that objected to publicly available metrics like 
the ones the Board proposed advocated a non-prescriptive, principles-
based approach, whereby auditors and audit committees would discuss 
potential metrics and the audit committee would determine which metrics 
and other information it finds meaningful and when it wants to receive 
and evaluate them. This approach, the commenters said, would encourage 
more tailored metrics that could be appropriately discussed in context 
and could change over time, adapting to changes in the audit 
environment, regulation, technology and audit processes, and the 
information needs of audit committees and investors and would 
prioritize relevance rather than consistency. Some commenters 
specifically recommended amending AS 1301 to mandate such a discussion 
(for example, initially in connection with audit planning and later as 
part of reporting on audit results). However, one investor-related 
group disagreed with this principles-based approach, asserting that it 
would not promote comparability or accountability because a set of 
principles would inevitably result in qualitative rather than 
quantitative disclosure and the information would not be comparable 
between firms and engagements and over time. This commenter asserted 
that the standardized metrics the Board proposed would be more useful 
to investors.
    This commenter also provided analysis of audit quality reports 
published by the Big 4 firms, observing that elements of the proposed 
firm-level metrics are already presented in those reports under a 
principles-based approach whereby each firm has developed its own 
metrics.\74\ The commenter noted that some of these metrics are 
qualitative, some are quantitative, some use different definitions, and 
some unfavorable metrics or facts may be excluded. This commenter also 
asserted that because metrics voluntarily published by firms are self-
defined and principles-based and are only at the firm level and not at 
the engagement level, they are largely unused by the investment 
community; they are regarded as marketing materials rather than 
investor information. This commenter emphasized that investors need 
more standardized information contextualized at the engagement-level to 
the company they are investing in and that are anchored to the firm-
level standardized information.
---------------------------------------------------------------------------

    \74\ This commenter provided several examples of inconsistencies 
in reporting metrics. For example, it stated while all Big 4 firms 
provide data on turnover or attrition, they are defined and 
calculated in different ways and any comparison among the firms is 
stymied.
---------------------------------------------------------------------------

    Several commenters noted that it would be possible for audit 
committees to provide additional public disclosure via the audit 
committee report in the issuer's proxy statement,\75\ which investors 
could consider in deciding whether to ratify the audit committee's 
selection of auditor and whether to vote for the board members who 
serve on the audit committee. Some of these suggested that the SEC 
could take action instead of, or along with, the PCAOB. Two argued that 
expanded audit committee disclosure would result in more relevant and 
decision-useful information for investors than the proposed metrics or 
would be a more direct way to address the information asymmetry than 
through this rulemaking. The other suggested that the SEC, together 
with the New York Stock Exchange and Nasdaq, should require inclusion 
of the metrics in the proxy statement to provide context for existing 
fee disclosures and to make investors aware of the metrics without 
having to search for them separately.
---------------------------------------------------------------------------

    \75\ See Schedule 14A. Information required in proxy statement, 
17 CFR 240.14a-101. If action is to be taken at a shareholders' 
meeting with respect to the election of directors, Item 7 of 
Schedule 14A requires the proxy statement to contain a report of the 
audit committee as specified in Item 407 of Regulation S-K, 17 CFR 
229.407.
---------------------------------------------------------------------------

    One firm suggested that the PCAOB gather the information underlying 
the metrics via inspection. However, this would defeat the objective of 
enhancing transparency to enable better informed decision-making by 
stakeholders.
    Another firm expressed concern that engagement-level metrics may 
not be useful because they will become available only once a year, with 
a delay of up to 35 days after the audit is completed until Form AP is 
filed. However, an investor-related group disagreed with this argument 
indicating that the financial results for companies are delivered with 
the same, or a more significant delay, to investors and usefulness of 
the information is not simply its immediate discrete disclosure but the 
trends in the information within and between companies over time.
    In addition, commenters raised general concerns about metrics 
requirements, including
    <bullet> the risk that publishing metrics would involve releasing 
confidential or nonpublic information, which may violate 
confidentiality obligations imposed by the American Institute of CPAs 
(``AICPA'') Code of Professional Conduct or conflict with non-US laws 
and regulations;
    <bullet> diverting the attention of the engagement team and firm 
resources away from performing quality audits;
    <bullet> lessening competition by releasing competitively sensitive 
information and reducing the number of registered public accounting 
firms, particularly in foreign jurisdictions, that would be available 
to play a substantial role in a large multinational group audit;

[[Page 99980]]

    <bullet> being burdensome and costly to compile data for each 
individual engagement;
    <bullet> becoming a ``check the box'' or compliance exercise that 
may not improve audit quality or provide meaningful transparency to 
stakeholders; and
    <bullet> implying that audit committees have a legal duty to 
consider metrics even though the PCAOB has no authority over audit 
committees.
    The Board adopted requirements for firms to provide both firm- and 
engagement-level metrics, with changes from its proposal as described 
in further detail below. The Board continues to believe that public 
reporting of a mandated set of firm- and engagement-level metrics will 
provide stakeholders with comparable information that is not currently 
available, would otherwise be difficult or impossible to obtain, and 
will position them to make better-informed decisions. Further, the 
Board believes that required public disclosures will facilitate 
development of standardized data for consistent comparison and analysis 
over time, which will be more valuable than the ad hoc, individualized 
disclosures that some firms have made on a voluntary basis or the 
information that could be provided by individual firms to audit 
committees or investors without any basis for cross-firm comparisons. 
The Board believes the new data points, when analyzed together with the 
audited financial statements, critical audit matters, auditor tenure, 
and other information about the firm and the engagement on Form 2 and 
Form AP, will provide more information about the audit and, therefore, 
the reliability of the auditor's report.
    The Board considered comments questioning the value of metrics, 
whether they will be used by investors and other stakeholders or would 
represent only a ``check the box'' compliance exercise, and whether 
they might contribute to information overload or have other negative 
consequences. Based on comments received from investors and other data 
provided, among other factors, the Board does not share those concerns. 
Investors and investor-related groups have commented throughout the 
course of this rulemaking that the metrics will be useful. A firm-
related group commented that, in a recent investor survey it conducted, 
almost all of the metrics the Board proposed were regarded as 
``extremely helpful'' by between 30% and 50% of participating 
investors. (The commenter did not indicate whether the survey allowed 
positive responses other than ``extremely helpful''--for example, 
``helpful'' or ``somewhat helpful''--and, if so, what the results were 
inclusive of those responses.) By contrast, the Board understands--
including from one commenter that argues that the voluntary approach 
should be maintained--that voluntarily provided metrics have not proven 
useful to investors. The Board believes that the value of voluntary 
metrics is undermined by a lack of the consistency and comparability, 
as well as enhanced credibility, that can be achieved through common 
definitions and calculations and required reporting.
    The Board also noted that similar objections--that the new 
information would not be used or would be confusing or misleading--were 
raised by many of the same commenters in connection with the Board's 
last two rulemakings requiring disclosure of additional information 
about audits and auditors: Form AP reporting of the name of the 
engagement partner and information about other firms participating in 
the audit, and auditor communication of critical audit matters. In both 
cases, these commenter concerns appear unsubstantiated. The Form AP 
data set is now one of the most frequently visited areas of the PCAOB 
website.\76\ Indeed, in an investor survey conducted by one commenter, 
79% of respondents indicated that they often or very often navigate to 
AuditorSearch, the search tool for Form AP data on the PCAOB website. 
As for CAMs, in a recent investor survey conducted by the same 
commenter, over 90% of the respondents indicated that CAMs play an 
important role in their investment decision-making.\77\ In addition, 
data aggregators, such as Audit Analytics, compile and make available 
data on CAMs, which suggests market demand for that information. The 
Board's experience suggests that contrary to concerns about irrelevance 
and information overload, stakeholders seek out additional information 
about auditors and audit engagements when it is available.
---------------------------------------------------------------------------

    \76\ In 2023, there were over 333,000 unique searches performed 
on AuditorSearch and the Form AP data set was downloaded over 2,000 
times. Information related to usage statistics can be found on the 
PCAOB's website (<a href="https://pcaobus.org/resources/auditorsearch">https://pcaobus.org/resources/auditorsearch</a>).

(July 2024) at 9.
---------------------------------------------------------------------------

    In lieu of public reporting, the Board considered the alternative 
of encouraging or mandating communication of engagement-level metrics 
to the audit committee, as many commenters suggested. However, such an 
approach would not achieve the Board's goals of increasing the 
information about audit engagements and audit firms available to 
investors and other stakeholders, and fostering comparability of data 
through mandated reporting based on common definitions and specified 
calculations. The Board also believes that a non-prescriptive, 
principles-based approach, whereby firms would potentially develop and 
discuss different metrics for different audit committees, drawn from 
different data and based on different definitions and calculations and 
changing over time, could itself create significant costs and 
challenges for firms without necessarily contributing to the audit 
committee's ability to understand the audit it oversees in a broader 
context.
    Of course, under the Board's final requirements auditors and audit 
committees will be free to discuss performance metrics--whether the 
metrics required under the Board's rules or additional or alternative 
metrics they develop themselves--through the kinds of discussions the 
commenters recommend. The Board is not requiring that auditors make 
metrics-specific communications at this time. However, where matters 
addressed by the metrics are the subject of an otherwise required 
communication, discussion of the metrics may be a useful part of the 
communication.
    The Board appreciates that the audit committee is charged by 
statute with responsibility for oversight of the auditor, and the Board 
cannot, and do not purport to, impose any obligations on audit 
committees or imply that audit committees have any specific duties in 
relation to metrics. The Board assumes that audit committees will 
fulfill their responsibilities as they see fit; whether that entails, 
for example, discussion of metrics with auditors or proxy statement 
disclosure regarding their consideration of metrics will be for them to 
determine.
    But the Board also notes that investors--including many investors 
that are themselves fiduciaries for others--have their own investment 
and voting decisions that they are called upon to make, like decisions 
about electing members of the board of directors, including those who 
serve on the audit committee, and ratifying the appointment of the 
auditor. And in the current environment, they have extremely limited 
access to information about the auditor's work--work that, after all, 
is undertaken for their benefit. By requiring public reporting of 
metrics, the Board is not suggesting that investors will have the 
ability or the responsibility to oversee the work of the auditor. 
However, they will have the

[[Page 99981]]

opportunity to gain new perspective to inform their decision-making. 
The Board agrees with a commenter that, far from undermining investor 
trust, this new transparency should enhance that trust by helping 
investors better understand the audit and the audit committee's 
oversight of it.
    The Board has determined to go forward with published metrics so 
that investors and other stakeholders will have direct access to the 
metrics and so that comparative data can be accumulated that will allow 
comparisons to be made across different firms and different 
engagements. As discussed below, the Board believes it has addressed 
many of the challenges associated with potential lack of comparability 
by narrowing the metrics to a group that it believes will send 
relatively clear, comprehensible signals that users will be able to 
interpret when taken together with the other information about the 
issuer and the auditor that is available to them. In the Board's view, 
public reporting is the most practical way for comparative data to be 
created and disseminated. While two commenters suggested that audit 
committees could obtain comparative data when they consider changing 
auditors, the Board's understanding is that is a relatively infrequent 
occurrence, and in any case is not a route available to other 
stakeholders.
    The Board also believes that gathering data and calculating the 
final metrics, given the subjects they address, will not be overly 
time-consuming or burdensome, and will not entail disclosure of 
confidential or otherwise protected information, as discussed below.
    Regarding the concerns of possibly disclosing confidential 
information and competition lessening effect due to public reporting of 
metrics; unintended consequences, including attention diversion, 
litigation and reputation risks, competition lessening effect, and 
audit labor market impacts; and costs, see discussions below.
3. Legal Authority
    Some commenters questioned the Board's statutory authority to 
require all or some of the proposed firm and engagement metrics. In 
addition, one commenter stated that the statement in the proposal that 
``this [rulemaking] would advance investor protection and promote the 
public interest by enabling stakeholders to make better informed 
decisions, promoting auditor accountability and ultimately enhancing 
capital allocation and confidence in our capital markets'' is beyond 
the Board's rulemaking authority. Other commenters questioned the 
Board's authority with respect to specific aspects of the rulemaking. 
Two commenters questioned how the requirements could extend beyond the 
accounting firms' issuer and broker-dealer audit practices. One of 
these commenters stated that it believes including non-issuer 
information could be misleading to stakeholders who may mistake such 
disclosures as being within the PCAOB's purview and that including the 
non-issuer portion of a firm's audit practice appears contradictory to 
the Board's pursuit of clarity through its proposed PCAOB Rule 2400, 
Proposals Regarding False or Misleading Statements Concerning PCAOB 
Registration and Oversight and Constructive Requests to Withdraw from 
Registration. This commenter suggested that if the Board intends to 
make clear what lies within and outside its purview through proposed 
PCAOB Rule 2400, the rulemaking related to firm- and engagement-level 
metrics should reflect similar principles.\78\ Another commenter 
suggested that several new requirements seem to require public 
production of information that is confidential or otherwise outside of 
or unnecessary for the Board's oversight function.
---------------------------------------------------------------------------

    \78\ To date, the Board has not adopted proposed PCAOB Rule 
2400.
---------------------------------------------------------------------------

    In accordance with Sarbanes-Oxley, the PCAOB is endowed with 
regulatory powers designed to ensure transparency, uphold high 
professional standards, and protect investors in the auditing process. 
This discussion outlines the statutory basis for this rulemaking as 
outlined in Sections 101, 102, and 103 of Sarbanes-Oxley. In 
particular, here and throughout the release, the Board discussed how 
the final rules will increase transparency regarding audit practices, 
increase the comparability and accessibility of information available 
to investors and others, and enhance investors' ability to efficiently 
and effectively make investment and voting decisions, in line with the 
Board's statutory mandate.
    Section 102 of Sarbanes-Oxley mandates that each registered firm 
must submit an annual report to the Board. Beyond this, Section 102 
grants to the Board the authority to require more frequent and detailed 
reporting, empowering the Board to require registered firms to report 
``such additional information as the Board or the Commission may 
specify.'' \79\ This authority must be exercised through PCAOB 
rulemaking that deems the information ``necessary or appropriate in the 
public interest or for the protection of investors.'' \80\ This 
statutory language supports the Board's authority to adapt its 
reporting requirements to the evolving needs of audit oversight, 
thereby enhancing investor protection and public confidence in the 
financial markets.
---------------------------------------------------------------------------

    \79\ 15 U.S.C. 7212(d).
    \80\ 15 U.S.C. 7212(b)(2)(H).
---------------------------------------------------------------------------

    The metrics the Board adopted in its release are important for 
increasing transparency regarding the practices of registered firms, 
particularly in their audits of issuers. By mandating the disclosure of 
this information, the PCAOB will enable investors and other market 
participants to have a clearer and more comprehensive view of the 
operational practices of the registered firms that audit issuers. This 
enhanced transparency will allow investors and other market 
participants to make more informed decisions, contributing to the 
integrity and reliability of financial reporting and audit practices.
    Additionally, Section 103 of Sarbanes-Oxley grants the Board 
authority to establish auditing standards and quality control standards 
``to be used by registered public accounting firms in the preparation 
and issuance of audit reports'' as ``may be necessary or appropriate in 
the public interest or for the protection of investors.'' \81\ Although 
the information the PCAOB requires from registered firms does not 
appear directly within audit reports, it is comfortably within the 
ambit of the Board's rulemaking mandate under Section 103--especially 
given the flexibility inherent in the statutory language.\82\ In brief, 
this mandate involves establishing the procedures and practices of 
registered firms that promote the quality and accuracy of audit 
reports, which extends to

[[Page 99982]]

overseeing how firms report their operational conduct.
---------------------------------------------------------------------------

    \81\ 15 U.S.C. 7213(a)(1).
    \82\ See Loper Bright Enters v. Raimondo, 144 S. Ct. 2244, 2263 
(2024) (the term ``appropriate'' ``leaves agencies with 
flexibility'' (citation and quotation marks omitted)); Kisor v. 
Wilkie, 588 U.S. 558, 632 (2019) (Kavanaugh, J., concurring in the 
judgment) (the word ``appropriate'' ``afford[s] agencies broad 
policy discretion''); Metrophones Telecommc'ns, Inc. v. Global 
Crossing Telecommc'ns, Inc., 423 F.3d 1056, 1068 (9th Cir. 2005) 
(``Given the reach of the [FCC's] rulemaking authority under 
201(b)''--which granted to the FCC the ``broad power to enact such 
'rules and regulations as may be necessary in the public interest to 
carry out the provisions of this Act' ''--``it would be strange to 
hold that Congress narrowly limited the Commission's power to deem a 
practice 'unjust or unreasonable.' ''); Brown v. Azar, 497 F. Supp. 
3d 1270, 1281 (N.D. Ga. 2020) (``[W]hen an agency is authorized to 
'prescribe such rules and regulations as may be necessary in the 
public interest to carry out the provisions of the Act,' Congress' 
intent to give an agency broad power is clear.''), appeal dismissed 
as moot, 20 F.4th 1385 (11th Cir. 2021) (mem.).
---------------------------------------------------------------------------

    In alignment with Section 103 of Sarbanes-Oxley, the PCAOB views 
the rule, form, and associated amendments requiring the metrics as 
fundamental auditing and quality control standards at their core. The 
information required by the metrics relates to practices of the firm 
that directly bear on the conduct of audits and ultimately the quality 
and accuracy of audit reports. By mandating the submission of this 
information to the PCAOB, the Board provides deeper transparency into 
the auditing practices that support issuer audits. The information 
required by the metrics will also support the Board's oversight and 
enhance the reliability of audit performance.\83\
---------------------------------------------------------------------------

    \83\ See, e.g., Mark DeFond and Jieying Zhang, A Review of 
Archival Auditing Research, 58 Journal of Accounting and Economics 
275, (2014) (asserting that audit quality improves financial 
reporting quality by increasing the credibility of the financial 
reports).
---------------------------------------------------------------------------

    Finally, the Board notes that Section 101 of Sarbanes-Oxley 
provides ancillary authority that supports the Board's primary powers 
in Sections 102 and 103.\84\ This provision enables the PCAOB to 
develop standards that protect investors and serve the public interest.
---------------------------------------------------------------------------

    \84\ For example, Section 101(c)(5) empowers the Board to 
perform additional duties or functions that are ``necessary or 
appropriate to promote high professional standards among, and 
improve the quality of audit services offered by'' registered firms 
and their associated persons. 15 U.S.C. 7211(c)(5). This provision 
empowers the PCAOB to implement measures that enhance the integrity 
and efficacy of the auditing profession. In addition, Section 
101(g)(1) provides rulemaking authority to the Board, specifying 
that the Board's rules, subject to the approval of the Commission, 
are to ``provide for the operation and administration of the Board, 
the exercise of its authority, and the performance of its 
responsibilities under'' Sarbanes-Oxley. 15 U.S.C. 7211(g)(1).
---------------------------------------------------------------------------

    Some firms and firm-related groups questioned the Board's statutory 
authority to require the reporting of the proposed metrics on the basis 
that the Board's rulemaking authority should correspond directly with 
the type of information outlined in Sarbanes-Oxley Section 102(b)(2) 
for the contents of registration applications. However, this 
interpretation significantly misreads the reporting provisions of 
Sarbanes-Oxley. Sections 102(b)(2)(H) and 102(d) clearly grant to the 
Board broad authority to require additional information in periodic 
reports that it finds necessary or appropriate to serve the public 
interest or protect investors.
    Section 102(b)(2) generally details baseline requirements for 
reported information and Section 102(b)(2)(H) primarily details 
requirements for any additional information the Board requires, 
providing that additional information in reports must be deemed 
``necessary or appropriate in the public interest.'' It is incorrect to 
construe those provisions as imposing a rigid limitation that restricts 
the content of reports exclusively to the types of information 
specified in Section 102(b)(2)(A)-(G) for initial registration 
applications. Indeed, Section 102(b)(2)(H) expressly contemplates the 
provision of ``other information'' the Board may require through 
rulemaking. This provision shows that Congress intended to provide the 
Board authority to require additional information beyond that 
enumerated in Section 102(b).\85\ By referencing this provision, 
Section 102(d) applies this broader authority to periodic reports that 
the Board finds necessary or appropriate to serve the public interest 
or protect investors. The Board's release has outlined how the 
disclosures mandated by the metrics will enhance transparency and 
bolster the PCAOB's oversight capabilities. Such enhancements are 
designed to ultimately improve audit quality. For example, as discussed 
more completely below, the final metrics will enhance (i) audit 
committees' ability to efficiently and effectively monitor and select 
auditors as well as (ii) investors' ability to efficiently and 
effectively make decisions about ratifying the appointment of their 
auditors and allocating capital. In addition, as an important indirect 
benefit, the final rules could further spur competition to the benefit 
of investors. Thus, the final rules align with the overarching 
objectives of Sarbanes-Oxley, and therefore are appropriate exercises 
of the Board's authority under Section 102.
---------------------------------------------------------------------------

    \85\ See Navajo Nation v. Dalley, 896 F.3d 1196, 1212-13 (10th 
Cir. 2018) (``Congress expressed its scope in broad terms, to 
encompass `any other subjects that are directly related to the 
operation of gaming activities.' But the key word here is `other.' . 
. . And applying the ordinary and everyday meaning of the word 
`other' . . ., it becomes patent that Congress did not intend for 
that clause to address the `subjects' covered in the preceding 
clauses of subsection (C)[.]'' (citation omitted)); see also, e.g., 
Madison v. Virginia, 474 F.3d 118, 133 (4th Cir. 2006) (``other 
Federal statute prohibiting discrimination'' is a ``catch-all 
provision''); Meehan v. Atl. Mut. Ins. Co., 2008 WL 268805, at *7 
(E.D.N.Y. Jan. 30, 2008) (``The term `other policies' now 
accomplishes the task of including all governmental activity and 
becomes a catch-all phrase including all other policies not already 
implied[.]'' (citations and quotation marks omitted)).
---------------------------------------------------------------------------

    In response to the concerns raised by firm commenters regarding the 
Board's use of Sarbanes-Oxley's relevant ``necessary and appropriate'' 
clauses, it is important to clarify that the Board has not claimed any 
implicitly delegated authority beyond the regulatory parameters 
established by Congress. The use of the Section 101, 102, and 103 
authorities in this rulemaking is firmly grounded within the explicit 
mandates provided by Sarbanes-Oxley, and is consistent with the 
statutory limitations and directives outlined in those provisions. The 
Board's application of these authorities has been specifically aimed at 
enhancing the transparency and quality of audits of issuers and broker-
dealers, which directly aligns with the Board's core mission to protect 
investors and the public interest. The Board has utilized the tools 
provided by Sarbanes-Oxley to carry out the responsibilities entrusted 
to it.
    Other commenters raised concerns about the Board's authority to 
include metrics extending beyond a registered firm's issuer and broker-
dealer audit practice. One of these commenters asserted that including 
non-issuer information could be misleading to stakeholders who may 
mistake such disclosures as being within the PCAOB's regulatory 
purview. The Board disagrees with these comments. The metrics the Board 
is requiring are designed to provide information that directly relates 
to firms' audits of issuers, and will be important for such matters as 
assessing auditor performance and resource allocation as it relates to 
issuer audits. For instance, in the Workload metric, firms are required 
to report not only the hours worked dedicated to issuer engagements but 
the entire workload of the personnel involved. This includes hours 
spent on non-issuer engagements, training, practice development, staff 
development, or other firm activities. A narrower focus, which only 
accounts for hours worked on issuer engagements, could provide an 
incomplete picture. It would fail to reflect the true extent of the 
auditor's commitments and how these may impact their capacity and focus 
on tasks in issuer audit work. Without this comprehensive view, 
investors and other stakeholders would lack important information to 
assess the potential risks over overcommitment on audit quality and 
auditor performance in audits of issuers. By requiring firms to report 
certain narrowly tailored information regarding their audit engagements 
and audit practices, the Board is not seeking to extend its purview to 
regulate those aspects of the firm's operations. Rather, in line with 
the Board's statutory authority, it is enhancing the transparency and 
the depth of information available to investors and other stakeholders 
concerning firms' audits of issuers.

[[Page 99983]]

4. Summary of the Metrics
    The Board adopted a set of firm-level and engagement-level metrics 
across eight areas. Firm-level metrics will provide a basis for drawing 
comparisons between firms as well as a baseline for evaluating 
engagement-level metrics. Engagement-level metrics will elicit more 
granular information and will enable comparisons over time and across 
engagements both within the firm and across other firms.
    Firm-level metrics will be disclosed on a new Form FM, Firm 
Metrics, and engagement-level metrics will be disclosed on a revised 
and renamed Form AP, together with the other engagement-specific 
information currently required (the name of the engagement partner and 
information regarding other firms participating in the audit).
    Most of the metrics the Board has adopted will be presented at both 
the firm and the engagement level. However, two metrics will be 
reported only at the firm level, because the Board believes aggregated 
data will be most meaningful or appropriate.
    The metrics are:
    <bullet> Partner and Manager Involvement. Hours worked by senior 
professionals relative to more junior staff across the firm's large 
accelerated and accelerated filer engagements and on the specific 
engagement.
    <bullet> Workload. For senior professionals who incurred hours on 
large accelerated and accelerated filer engagements, average weekly 
hours worked on a quarterly basis, including time attributable to all 
engagements, administrative tasks, training, and all other matters.
    <bullet> Training Hours for Audit Personnel. Average annual 
training hours for partners, managers, and staff of the firm, combined, 
across the firm and on the engagement.
    <bullet> Experience of Audit Personnel. Average number of years 
worked at a public accounting firm (whether or not PCAOB-registered) by 
senior professionals across the firm and on the engagement.
    <bullet> Industry Experience. Average years of career experience of 
senior professionals in key industries audited by the firm at the firm 
level and the audited company's primary industry at the engagement 
level.
    <bullet> Retention of Audit Personnel (firm-level only). Continuity 
of senior professionals (through departures, reassignments, etc.) 
across the firm.
    <bullet> Allocation of Audit Hours. Percentage of hours incurred 
prior to and following an issuer's year end across the firm's large 
accelerated and accelerated filer engagements and on the specific 
engagement.
    <bullet> Restatement History (firm-level only). Restatements of 
financial statements and management reports on ICFR that were audited 
by the firm over the past three years.

------------------------------------------------------------------------

    The final suite of metrics focuses primarily on information about 
audit personnel. The Board believes these metrics will provide new 
insights into how engagements are staffed, including the extent of 
involvement of senior personnel; auditors' overall workload; retention 
of personnel across the firm; and levels of training, audit experience, 
and industry-specific expertise. The final metrics will also provide 
information about the extent of audit work completed prior to the 
issuer's year end, an aspect of the audit process that the Board 
believes is associated with improved audit outcomes, and about the 
firm's history of restatements, a key measure of audit outcomes.
    This new information will allow users to draw inferences about 
audits and audit firms that are not possible today. Some may relate to 
specific metrics. For example, a heavy workload for a particular 
engagement team relative to the firm average or compared to peer firms 
may raise questions about the quality of the work performed. 
Conversely, a relatively high level of industry-specific experience, 
particularly for an engagement in an industry requiring specific 
accounting and auditing expertise, would be a positive signal. Other 
inferences may relate to combinations of metrics. For example, the 
personnel-related metrics, taken together, give an overall sense of how 
an engagement is staffed that can be compared to firm averages and to 
engagements for similar issuers. It is possible that the precise 
numerical values of metrics may be important in some cases, but in 
general the Board believes the metrics will be more useful to convey a 
sense of whether a particular engagement or firm appears fairly typical 
or is an outlier in one or more respects. This should provide a richer 
context for understanding the work of the auditor than the current 
environment of almost no publicly available information.
    Based on the Board's oversight activities, it appears that the 
largest firms are already tracking data in many of these areas,\86\ and 
the Board believes that all firms should be able to capture the data 
required by the metrics without undue burden. Many of the metrics are 
based on data that firms already track or will be required to track for 
purposes of other PCAOB requirements. For example, Partner and Manager 
Involvement and Allocation of Audit Hours are based on the same ``total 
audit hours'' that firms are already required to track for Form AP 
reporting. Training hours will reflect the same information that firms 
track to ensure proper licensing of their personnel. Restatement data, 
to the extent firms are not already tracking it, is required to be 
tracked under QC 1000.\87\ In addition to required data, many firms 
track the experience of their personnel, as well as industry 
experience, for use in marketing materials and for inclusion in 
requests for proposals, and some firms already track staff retention 
and turnover metrics as part of their human capital management. Firms 
should be able to generate other data required by the final metrics, 
such as Workload,

[[Page 99984]]

from their existing timekeeping systems with minimal additional effort.
---------------------------------------------------------------------------

    \86\ This point is discussed more fully below.
    \87\ See QC 1000.64g, Note to QC 1000.67e.
---------------------------------------------------------------------------

    Below, the Board provides a detailed discussion of key terms and 
concepts used in the metrics, as well as a description of each final 
metric and its calculations.
5. Comparability
    Developing comparable data regarding firms and engagements has been 
one of the Board's key objectives throughout this rulemaking. As noted 
previously, the information currently provided in firm transparency 
reports is not based on common definitions or methods of calculation, 
which prevents users from being able to make comparisons across firms 
or over time. The Board believes that an important benefit of mandatory 
reporting will be the ability of investors and other stakeholders to 
compare the metrics, within the same firm over time, among firms, and 
among engagements.
    The basic approach of the Board's final rules--a required set of 
metrics, derived from specified calculations incorporating consistently 
defined terms and concepts--is designed to generate comparable data 
with respect to firms and engagements that are subject to the reporting 
requirements. One investor-related group agreed that standardized and 
contextualized metrics will provide investors with a consistent data 
set for analysis over time and for comparison between companies and 
firms and a set of standardized data is more valuable than the ad hoc 
individual measures that some firms have made on a voluntary basis.
    In some cases, considering the importance of scalability, the Board 
has also designed the proposed metrics as percentages (e.g., relative 
to total audit hours) or averages where the Board believes that will 
provide more comparability across firms and engagements than methods 
based on absolute amounts.
    Several firms and firm-related groups expressed skepticism about 
whether the metrics could generate comparable data because of inherent 
differences across firms and engagements, either with regard to any 
metrics or engagement-level metrics specifically. For example, one 
commenter said that differences between firms and among engagements 
will create heterogeneity in the underlying data, so that cross-
sectional differences and changes over time will be unclear and 
challenging to interpret, and will cause confusion. Another commenter 
emphasized the importance of comparability between larger and smaller 
firms so that investors and audit committees can interpret them 
appropriately.
    Two commenters stated that if context, including qualitative 
aspects of data, is necessary to understand the metrics, that would 
suggest that the data are not comparable, which could mean that the 
metrics are not decision-useful and are at risk of misinterpretation. 
One commenter expressed the opposite concern, that metrics would become 
homogenized over time due to peer comparisons, making them considerably 
less useful to investors.
    One commenter asserted that the Board's choices in defining terms 
and specifying calculations undermine the comparability of the 
metrics--for example, because some metrics include issuers other than 
accelerated or large accelerated filers, the Board's proposed industry 
classification taxonomy differs from the one used by the SEC, and its 
proposed period for measuring restatements differs from the period used 
by a commonly-used data provider. These issues are addressed below in 
the discussion of the final metrics.
    With regard to firm-level metrics, several commenters expressed 
concern that some or all of the metrics would not be comparable across 
firms. They cited factors such as the size of the firm (including the 
number of issuer and non-issuer engagements), specialization of the 
firm's audit practice, strategies, priorities, investments, 
organizational structure and quality control system of the firm, and 
size of the issuer (which affects, among other things, whether an 
integrated audit is required).
    Several commenters expressed particular concern about comparability 
between U.S. and non-U.S. firms because non-U.S. firms tend to have 
structural, jurisdictional, and cultural aspects that differ from U.S. 
firms. In addition, non-U.S. firms may have a relatively smaller issuer 
audit practice, which could skew metrics that are based on the entire 
practice because there may be significant differences between issuer 
audits and the rest of the firm's audit practice, and could increase 
the volatility of metrics based on the issuer practice because of its 
small size. One of these commenters also criticized the application of 
metrics to non-U.S. firms because they would not capture the 
qualitative benefits of being a part of a global network (e.g., use of 
consistent policies and procedures that drive use of training, 
technology, consultation and other centrally available support across 
the network). Another commenter also noted that some non-U.S. firms may 
publicly report firm-level metrics on similar topics, such as workload, 
using different calculation methods under PCAOB and local reporting 
requirements, which would be costly for these firms and potentially 
confusing to the users.
    Many commenters expressed concern that engagement-level metrics are 
inherently incomparable. Commenters suggested a number of factors that 
could affect the comparability of engagement-level metrics, some 
relating to the firm (e.g., the firm's organizational structure, IT 
systems, resources, and audit methodologies), some to the individual 
audit engagement (e.g., selected audit approaches including substantive 
analytical procedures or test of details, audit findings including 
internal control deficiencies, use of technology, first year or 
recuring engagement, and risk of material misstatement), and some to 
the issuer (e.g., business structure (including the extent of 
centralization or decentralization and number of business units), 
complexity of the organizational structure and IT infrastructures, 
number of significant unusual transactions, and business and industry 
risks affecting the issuer). In addition, one commenter noted that 
there are significant developments (e.g., in delivery models, 
technology, and professional rules and standards) that affect the way 
audits are performed each year.
    The Board solicited comment on whether comparability could be 
enhanced by further segmenting firm-level reporting (for example, on 
the basis of the size of the firm or the size of the issuer) or 
engagement-level reporting (for example, on the basis of industry 
sector, region, or whether it is a first-year audit). One commenter 
stated that all stakeholders would benefit from a consistent 
calculation methodology and comparable presentation format of firm-
level reporting. Several commenters indicated that more disaggregated 
data for engagement- or office-level reporting could be useful, though 
one acknowledged that this benefit would need to be weighed with the 
cost of requiring this data. Other commenters cited challenges 
associated with providing subsets of information, including that firm 
and issuer sizes change over time and that smaller firms' metrics could 
disclose individual client information. One of these asserted, however, 
that the reported data could be disaggregated and compared without 
additional data fields being collected.
    The Board determined not to collect additional data fields or 
require additional segmentation of the metrics at this time because of 
the potential cost and complexity it would add to the process of 
compiling and reporting the metrics. Stakeholders that want to perform 
more detailed analysis (for

[[Page 99985]]

example, segmenting data based on size of the issuer, size of the firm, 
region, or industry sector) will be able to do so using information 
that is already publicly available in combination with the metrics.
    The Board understands that firms differ from each other in the 
number and types of audits they perform and in their resources, such as 
the number, experience, and degree of specialization of their people as 
well as their access to technological resources and resources provided 
by networks. The Board also understands that engagements differ based 
on factors such as the size of the engagement, the industry of the 
company, the risks related to the company and the audit, whether it is 
a new engagement for the firm or the engagement partner.
    However, the Board does not believe that such differences make 
useful, comparable metrics impossible. As one commenter noted, 
investors are experienced in using a wide array of performance metrics, 
such as non-GAAP measures and key performance indicators, and are able 
to analyze them despite a lack of perfect comparability between 
companies or over time. Indeed, the commenter argued that, due to the 
nature of the audit process and audit firms, the proposed firm and 
engagement metrics have a greater propensity for comparability than 
many companies whose financial results investors already analyze.
    The Board believes it has also addressed many of the challenges 
associated with potential lack of comparability by narrowing the 
metrics to a group that should send relatively clear, comprehensible 
signals in a variety of different contexts. Metrics on workload, 
training hours, experience in public accounting, retention of 
personnel, and restatement history should send a clear signal, 
regardless of the circumstances of the firm and the engagement. Metrics 
on partner and management involvement and allocation of audit hours may 
be more influenced by those circumstances. For example, unusually high 
involvement by senior professionals could signal an especially complex 
audit or one that encountered unexpected problems; a relatively low 
percentage of audit hours incurred before year end could signal a 
poorly planned audit or simply that, due to the nature and scope of a 
company's business, it was unnecessary or impractical to perform many 
audit procedures prior to year end. The Board has limited the scope of 
the Partner and Manager Involvement, Workload, and Allocation of Audit 
Hours metrics to large accelerated filer and accelerated filer 
engagements to enhance the comparability of the underlying data. The 
metric on relevant industry experience may also be influenced by the 
circumstances of the firm and the engagement in that industry 
experience may be more important in some industries than others. 
However, the Board believes users will be able to interpret this metric 
when taken together with the other information about the issuer and the 
auditor that is available to them. Common definitions and consistent 
methodology will also contribute to comparability. Taken together, the 
metrics should enable users to make both broad comparisons across the 
full population of reporting firms and accelerated filer and large 
accelerated filer audits, and more targeted comparisons across smaller 
subgroups of similar firms and engagements, and will be a very 
significant improvement over the information that is currently 
available--ad hoc reporting by the largest firms at the firm level, and 
essentially no information at the engagement level.
    Of course, any additional context that firms believe is necessary 
for proper understanding can be provided as narrative disclosure. While 
narrative disclosure will not make the metrics comparable, it will 
balance the comparability of standardized metrics disclosure with the 
ability to provide further context if needed. For example, a firm could 
provide an explanation for why a metric changed significantly from what 
was reported in the prior year.
6. Time Period Covered by the Metrics
    Firm-level metrics are reported as of September 30, generally 
covering the period from October 1 of the previous year through 
September 30.\88\ Specific commenter feedback regarding the reporting 
period is discussed in detail below. Firms are required to file Form FM 
on or before November 30, 61 days after the end of the reporting 
period, also discussed below.
---------------------------------------------------------------------------

    \88\ For two of the metrics areas the Board proposed, Quality 
Performance Ratings and Compensation and Audit Firms' Internal 
Monitoring, firms would have reported based on their own internally 
established cycles. Neither of these is included in the metrics the 
Board adopted.
---------------------------------------------------------------------------

    Related to the Training Hours for Audit Personnel metric, the Board 
understands that many firms already have defined periods or cycles that 
may not align with the final reporting date (e.g., for which the firm 
tracks training data in order to comply with state continuing 
professional education (``CPE'') reporting requirements). Therefore, 
the firm is permitted to use its already-established training calendar 
cycle for calculation and reporting of this metric, provided that the 
cycle covers a 12-month period (which is expected to be consistently 
applied). The Board does not believe that the data will be especially 
sensitive related to any particular 12-month period. The Board believes 
allowing firms flexibility to use their internally established dates 
for this metric is appropriate and still provides the comparability 
discussed above since all firms would be reporting this metric based on 
a 12-month period.
    For engagement-level metrics, which will be reported on Form AP, 
the data and information underlying the reported metrics will generally 
be based on the most recent period's audit. However, some engagement-
level metrics relate to information about personnel on the engagement, 
such as Experience of Audit Personnel, and these metrics will reflect 
information that may not be directly related to the most recent 
period's audit. Specific commenter feedback regarding the reporting 
period and filing date of Form AP is discussed in detail below.
    In addition, the time period covered by each metric also is 
discussed in more detail below.
7. Rounding and Use of Estimates
    Many of the metrics involve the calculation of a numerical value 
that may result in very small fractional parts. Consistent with the 
proposal, firms are required to report metrics that are rounded to the 
nearest whole number, except where additional decimal places (no more 
than two) are needed to properly interpret the result or to enable 
comparison to prior periods.
    In calculating the firm- and engagement-level metrics, actual 
amounts should be used, if available. However, if actual amounts are 
unavailable, firms are permitted to use a reasonable method to estimate 
the components of a calculation. This approach is consistent with 
existing Form AP, which allows firms to use a reasonable method to 
estimate certain information required in the calculation of total audit 
hours.\89\ Firms are also required to document in their files the 
method(s) used to estimate amounts when actual amounts are unavailable.
---------------------------------------------------------------------------

    \89\ See Instructions to Part IV of Form AP as currently in 
effect. Under the amendments to Form AP adopted by the Board, this 
appears in General Instruction 9, as amended.
---------------------------------------------------------------------------

    Commenters generally agreed with the proposed approaches, with one 
commenter agreeing that rounding and estimation should be permitted for 
all metrics. Other commenters stated that rounding and estimation will 
be

[[Page 99986]]

especially important for metrics related to the reporting of hours, 
with two of these pointing to the subjectivity involved with the 
proposed metrics that would require allocation of hours to specific 
audit areas.\90\ One commenter stated that the PCAOB should not 
restrict the number of decimal places. However, the Board believes that 
limiting reporting to hundredths will allow for the presentation of an 
appropriate level of detail while ensuring comparability of 
presentation and avoiding the technical issues that could arise with 
unlimited digits.
---------------------------------------------------------------------------

    \90\ The proposed Audit Hours and Risk Areas metric is not 
included in the metric that the Board adopted, as discussed further 
below.
---------------------------------------------------------------------------

8. Operational Narrative Disclosure
    In order to give firms the ability to provide any context they 
thought necessary for an appropriate understanding of the reported 
metrics, the Board proposed that firms would be permitted, but not 
required, to provide a brief narrative disclosure (no more than 500 
characters per metric) to accompany any, or all, of the firm-level and 
engagement-level metrics reported on Form FM or Form AP. While some 
commenters agreed with the proposal to provide firms with the ability 
to include an optional narrative to accompany the metrics, one 
commenter explicitly agreed with the proposed 500-character limit, one 
commenter asserted that the 500-character limit greatly limits the 
context that could be provided, and one commenter suggested revising 
the character limit to no more than 1,000 characters. Two commenters 
suggested increasing the character limit beyond 500 characters without 
suggesting an upper limit. Approximately half of the commenters 
suggested that there should be no character limit imposed on the 
optional narrative. A firm-related organization also suggested that the 
narrative be mandatory and not optional, while a firm suggested that 
the utility of metrics would be diminished without potentially 
extensive accompanying narrative.
    One commenter suggested that firms can also provide a link in the 
narrative to their transparency reports and audit quality reports if 
they wish to provide further context to the metrics. One commenter 
stated that there should be guidelines such as the narratives being 
factual, directly relevant to the metric, and free from promotional or 
marketing language. Another commenter stated that it would provide the 
following narrative in Form FM, potentially with respect to every firm 
metric:

We do not believe any one metric or even a combination of metrics is 
necessarily indicative of audit quality, nor is it useful or 
productive to speculate on the questions reviewers of this 
information may have on each metric for every audit. We further 
discuss this metric in our Audit Quality Report, along with the 
measures we believe are better indications of our audit quality.\91\
---------------------------------------------------------------------------

    \91\ See Letter from PricewaterhouseCoopers LLP (June 7, 2024).

    Taking into consideration commenter feedback, the Board is 
retaining the option to provide narrative disclosure with each metric 
but expanding the character limit to 1,000 characters. The Board 
believes this character limit strikes the right balance between 
allowing firms the ability to provide any contextual information they 
believe is necessary to interpret the results of a particular metric 
while also managing the length of the forms and keeping them to a 
manageable size.\92\
---------------------------------------------------------------------------

    \92\ Nothing in PCAOB rules and forms, including Form FM and 
Form AP, provides for incorporation by reference of external 
documents or other materials.
---------------------------------------------------------------------------

    In addition, in an effort to assist firms in making the optional 
narrative disclosures as helpful and substantive as possible, to help 
remind firms of their responsibility under QC 1000 to produce and 
report information that is accurate and not misleading, and to reduce 
the possibility that users will find the narrative confusing or in 
conflict with the required metrics, the following provision has been 
added as a general instruction to Form FM and a note to Part VI of Form 
AP to provide additional direction to those firms electing to provide 
an optional narrative for any metric:

``When the Firm elects to provide a brief narrative to accompany any 
of the Items in [the part of the form in which metrics are 
reported], language should be concise and focused on the reported 
metrics, with a view to facilitating the reader's understanding of 
the metrics.''
Firm and Engagement Metrics
1. General Comments
    Investors and investor-group commenters were broadly supportive of 
the proposed metrics, saying that the metric areas would provide 
investors with decision-useful information about audit firms and 
audits. However, they expressed mixed views on certain specific metric 
areas. These commenters also suggested additional metric areas, 
including investments in both training audit professionals and in 
technology, and further details related to PCAOB inspection results 
(e.g., Part I.A deficiencies). The Board has addressed these comments 
in the discussion of each metric area below. On the topic of 
implementation of the proposed metrics, one commenter requested 
analytical tools and research showing how investors might use metrics. 
The information disclosed on Form FM will be available in a searchable 
database on the Board's website, similar to the Form AP database, and 
will provide users of the information the ability to perform 
comparisons across engagements.
    Firms and firm-related groups were broadly supportive of some of 
the proposed firm-level metrics. However, they generally opposed public 
reporting of engagement-level metrics, asserting that no amount of 
context around engagement-level metrics would provide an appropriate 
basis for public reporting. These commenters suggested that the audit 
committee, being deeply familiar with the company, the audit, and the 
independent auditor, is the only party equipped to appropriately 
interpret the metrics. Instead of public reporting, they suggested 
several alternatives, including adding a requirement for communication 
to the audit committee under AS 1301; expanding SEC requirements for 
audit committee disclosures; encouraging voluntary reporting; issuing 
PCAOB Spotlights, practice alerts, or guidance; and performing further 
outreach before adopting any requirements. These alternatives are 
discussed in greater detail above. One commenter suggested that the 
PCAOB take a proactive role in educating all users as to the proper use 
of reported metrics, including the need for them to be interpreted in 
context and making users aware of potential dangers and drawbacks 
associated with a mere comparison of isolated metrics between firms. 
The Board discussed the forms and how the data can be accessed in more 
detail below.
    Commenters generally expressed concern that proposed metrics were 
not all calculated from the same data sources. Some metrics were 
calculated on the basis of all audit engagements, others on the basis 
of issuer engagements, and engagement-level metrics on the basis of 
large accelerated and accelerated filer engagements. Some commenters 
suggested that calculating firm-level metrics based solely on total 
audit hours on large accelerated and accelerated filer engagements may 
result in more comparable data among firms. The Board discussed this in 
greater detail below.
    Other commenters recommended that the PCAOB establish criteria for 
determining which metric areas warrant public disclosure, so as to 
build in flexibility over time and minimize the risk of 
misinterpretation. The following

[[Page 99987]]

criteria were among those suggested by these commenters:
    <bullet> Is the metric's relation with audit quality unambiguous?
    <bullet> Can the metric be appropriately interpreted on its own, 
without additional context (e.g., client mix or complexity--size, 
industry, international operations; firm's audit approach; etc.)?
    <bullet> If disclosure of the metric results in behavioral change 
in audit firms, does research suggest the change will improve audit 
quality or, at least, not adversely impact audit quality?
    <bullet> Will the metric require firms to develop systems, 
processes, and procedures that they do not already have and at a 
reasonable cost?
    <bullet> Will the metric impose ongoing administrative burdens on 
engagement teams that result in a reallocation of effort away from 
audit quality enhancing activities?
    <bullet> Will the metrics align with measures used in the system of 
quality control to manage the audit practice?
    <bullet> Will the metrics meet the information needs of the users?
    <bullet> Will the disclosure of metrics not result in the 
communication of proprietary information?
    In responding to commenters and articulating the rationale for 
adopting the firm- and engagement-level metrics below, the Board 
considered the views of commenters, including these suggested 
evaluation criteria. The Board believes some of the suggested criteria 
would impose an unworkable framework that is inconsistent with the 
Board's regulatory objectives. For example, the Board does not think it 
is necessarily practicable to establish an ``unambiguous'' relationship 
to audit quality, as suggested, for any individual metric, nor would 
such an exercise be consistent with the intended uses of the metrics, 
which envisions their being considered as part of the total mix of 
information available to stakeholders. Moreover, the Board believes 
that imposing rigid criteria for each proposed metric imposes too high 
a burden and is not conducive to effective regulation. It does not 
permit the Board to account for facts and circumstances unique to 
individual metrics and their potential uses, nor does it account for 
the holistic manner in which the Board intends for the metrics to be 
used or developing information about the utility of the metrics over 
time.
    A number of commenters recommended that the PCAOB engage in 
additional stakeholder outreach, sponsor pilot programs, or otherwise 
engage in further study and research before finalizing the metrics 
requirements, or even withdraw the proposal. Based on the lengthy 
project history described in Section II, which includes repeated input 
over time from the Board's advisory groups, multiple rounds of public 
notice and comment, study of relevant academic literature, study of 
voluntary firm disclosures, and consideration of actions taken in other 
jurisdictions, the Board does not believe further study is necessary or 
that the Board's investor protection mission would be served by 
delaying adoption of the final rules. However, the Board will monitor 
and determine if further implementation resources or support is 
appropriate for users of these metrics.
2. Key Terms and Concepts
    As described below, the Board developed certain key terms and 
concepts that were used in calculating the proposed metrics. Where 
practical and relevant, these key terms and concepts align with 
existing definitions in PCAOB standards and rules. In other cases, the 
Board has developed new definitions and new descriptions of terms 
specifically for use in the metrics, which are not intended to inform 
the interpretation of other rules, standards, or forms of the PCAOB. 
The Board provided the key terms and concepts along with formulas for 
calculating each metric to drive consistency among firms and engagement 
teams.
    One investor-related group said that the units of account (e.g., 
hours, years of experience) or measurement used within the proposed 
metrics are sufficiently standardized and adaptable by firms as they 
are commonly used within audit practice or defined within the existing 
standards.
    Some commenters raised concerns about the definitions and 
descriptions of the population used for various metrics or about not 
having a defined set of terms applicable to all standards and rules. 
Other commenters questioned whether the PCAOB had provided sufficient 
guidance to address potential variations in the interpretation and 
application of terminology used in the metrics or asserted that not 
having sufficient guidance would add complexity and challenges in 
calculating the metrics and understanding them or result in 
inconsistent reporting of metrics or lack of comparability across audit 
firms and audits engagements. Two of these commenters recommended that 
the PCAOB create a glossary of defined terms to support consistent use 
of terms throughout the standards and rules or conduct additional study 
to evaluate the defined terms in the proposal against terms already 
defined in other PCAOB standards and rules. Another commenter raised a 
concern that defining terms and specifying computations for each metric 
undermines their comparability.
    Some firms offered examples of areas where they suggested that 
clarification would be needed, which the Board discussed below in the 
context of the relevant metrics. In general, however, the Board 
continues to believe that the use of defined terms is critical to 
driving consistent calculation of the metrics.
    Other firms questioned why different metrics are based on different 
underlying data (for example, total audit hours vs. total hours worked 
or engagement team vs. core engagement team). In general, the Board's 
choice of the data on which to base a metric is tailored to the 
intended objective of the metric, and also takes into account the 
practicality and potential costs associated with gathering data and 
calculating the metrics. The Board does not believe that metrics based 
on a single data set would be as clear or as informative.
    The Board addresses specific concerns raised in the discussion of 
each metric below. The Board has clarified certain terms and concepts 
used or revised the descriptions of proposed terms and concepts after 
consideration of the specific comments received.
i. Populations Covered by the Metrics
a. Partners and Managers (Used in All Metric Areas Except for 
Allocation of Audit Hours and Restatement History); Staff (Used in 
Training Hours for Audit Personnel)
    While some of the functional roles played by individuals involved 
in an audit are otherwise defined and used in the Board's standards 
(e.g., engagement partner \93\ and EQR),\94\ the Board proposed to 
clarify following additional functional roles referred to in the 
metrics to ensure consistent reporting by firms.
---------------------------------------------------------------------------

    \93\ See paragraph .A1 of AS 1201, Supervision of the Audit 
Engagement (``the member of the engagement team with primary 
responsibility for the audit'').
    \94\ See AS 1220, Engagement Quality Review, for a description 
of the engagement quality reviewer's role.
---------------------------------------------------------------------------

    Partners--Partners or persons in an equivalent position (e.g., 
shareholders, members, or other principals) who participate in audits; 
\95\
---------------------------------------------------------------------------

    \95\ As noted in the proposing release, the Board believes this 
is consistent with the use of the term ``partner'' in the Board's 
auditing standards. Although the Board does not usually state 
expressly that partners are limited to those who participate in 
audits, as a practical matter the Board's auditing standards apply 
only in those circumstances.

---------------------------------------------------------------------------

[[Page 99988]]

    Managers--Accountants or other professional staff commonly referred 
to as managers or senior managers (or persons in an equivalent 
position) who participate in audits; and
    Staff--Accountants or other professional staff who participate in 
audits and are not partners or managers.
    Some engagement-level metrics differentiate between engagement 
partner and the other partners who participate in the audit. The Board 
believes the differences between the responsibilities borne by 
engagement partner and those of other participating partners justify 
presenting data for the two categories separately in those metrics. For 
firm-level metrics, ``engagement partners'' include all partners who 
served as the engagement partner on any audit the firm performed of an 
accelerated filer or large accelerated filer. Partners that are 
included in the metrics as an engagement partner are not included as an 
``other partner,'' even if they served in a non-engagement partner role 
in other audits (in other words, partners are only counted once within 
any metric).
    The Board adopted the definitions of partners, managers, and staff 
as proposed, with clarifications discussed below.
    The Board solicited comment on whether the proposed definitions of 
partners, managers, and staff are clear and appropriate. Two commenters 
agreed that the proposed definitions for partners, managers, and staff 
are clear and appropriate, one saying that linking the definitions used 
in the metrics to existing definitions would help in preventing 
multiple definitions throughout the auditing standards. However, some 
commenters expressed concern that titles and roles are not consistent 
across firms or most firms have roles which do not clearly or obviously 
reconcile to the roles listed. One of these commenters also raised a 
concern about continuing emphasis on the engagement staffing model that 
currently exists, on the basis that artificial intelligence and other 
tools could affect the staffing of audit engagements in the future. 
This commenter recommended including ``contractors'' engaged by firms 
in the definition and clarifying whether the definitions are meant to 
be descriptions of the roles rather than legal interpretations of the 
roles. Another commenter recommended aligning the definitions of 
partners, managers and staff with the definition of engagement team, by 
using the phrase ``who perform audit procedures'' instead of ``who 
participate in audits'' to avoid inclusion of personnel who may 
participate in audits in an administrative or project management 
function, but who do not perform audit procedures. Another commenter 
expressed concern that audit effort associated with roles typically 
referred to as ``national office'' and ``professional practice 
development,'' especially for managers through partners, would be 
excluded from the definitions and calculations of the metrics.
    For the definition of partners, one commenter questioned whether 
the definition is intended to have any alignment with ownership 
interests in a firm and requested clarification as to how a leadership 
level role such as a managing director would be classified because, in 
the commenter's view, that role does not appear to meet the definition 
of either a partner or a manager.
    For the definition of managers, the same commenter requested 
clarification on whether the manager title is based on the person's 
general title in the firm because, for example, in certain cases an 
experienced supervisor may serve a manager capacity on a less complex 
engagement. Another commenter suggested adding a specific number of 
years of audit experience to the definition of managers because of the 
risk that firms could inflate percentage of audit hours incurred by 
managers by changing the titles of more junior professionals to 
increase the number of managers.
    The Board adopted the definitions of partners, managers, and staff 
as proposed. Because there are differing legal structures and titles 
among firms, the Board is providing foundational definitions so that 
each firm can allocate its professionals in three levels: partners, 
managers, and staff. The Board believes that the vast majority of firms 
have these three levels, and that, although staffing models may change 
over time, these levels are likely to be retained for the foreseeable 
future. The Board also believes that other job titles, such as managing 
director, can be fit into the appropriate category based on the level 
of responsibility assigned to them. For example, in a firm where 
managing directors are given similar responsibilities as the firm's 
principals (for example, signing authority on audit engagements), they 
would be treated as partners under the Board's definition; otherwise, 
they would align with managers. Similarly, professionals in a firm that 
does not use the title ``manager'' would be reported as managers if 
they are assigned the duties that are typically carried out by managers 
and senior managers at firms that do use those titles. Professionals 
who work under the firm's direction and control and function as the 
firm's employees, such as secondees and contractors, may or may not 
have these titles but would be reported based on their level of 
responsibility and decision-making authority. In all cases, the 
determination would be made based on the responsibilities, decision-
making authority, and scope of duties of the person. If necessary, 
firms could utilize the optional narrative disclosure to describe how 
the firm aligned their categories of professionals with partners, 
managers, or staff levels.
    The Board considered adding a specified minimum number of years of 
audit experience in the definition of manager but determined not to. 
Some managers qualify for promotion with fewer years of audit 
experience due to other relevant education or experience. The Board was 
concerned that building a minimum number of years of audit experience 
into the definition would result in people with the responsibilities 
and title of manager being required to be reported as staff, making the 
metrics less meaningful while increasing the administrative burden 
associated with reporting.
    The Board did not use the phrase ``who performed audit procedures'' 
in the definitions of partners, managers, and staff because use of this 
term would exclude professionals who do not perform audit procedures--
for example, partners who only conduct engagement quality reviews \96\ 
or national office personnel in connection with certain types of 
consultations that are not audit procedures.
---------------------------------------------------------------------------

    \96\ Engagement quality review is not considered the performance 
of an audit procedure. See AS 1220.07 (The EQR ``should not make 
decisions on behalf of the engagement team or assume any of the 
responsibilities of the engagement team.'').
---------------------------------------------------------------------------

    Because the definitions of managers and staff are limited to 
``accountants or other professional staff,'' administrative personnel 
are not included.
    In the Board's proposal, the Board generally did not specify how to 
account for promotions within the reporting period from one level to 
another (e.g., from manager to partner),\97\ although the Board noted 
that firms would be expected to be consistent in their approach across 
metrics. The only commenter to address this issue supported the 
flexibility

[[Page 99989]]

proposed with respect to the treatment of promotions. Consistent with 
the proposal, the final rules do not impose any prescriptive 
requirements regarding the reporting of professionals whose job title 
or responsibilities change during the reporting period. However, the 
Board believes that treating such transitions inconsistently, whether 
within a metric or across metrics, would be misleading and the Board 
expects firms to report such changes in a consistent way.
---------------------------------------------------------------------------

    \97\ Note, however, that the Retention of Audit Personnel metric 
treats promotions as if they had occurred at the beginning of the 
year. See note to Item 4.6 of Form FM.
---------------------------------------------------------------------------

(1) Participate in Audits (Used in the Terms Partners, Managers, and 
Staff)
    ``Participate in audits'' is a broad concept that would include the 
work of all professionals (partners, managers, and staff) that are 
involved in the firm's audits, including tax personnel, information 
technology (``IT'') personnel, and employed specialists.
    The Board proposed the phrase ``participate in audits'' rather than 
referring to the activities of individuals assigned to a specific 
business line, such as the firm's audit practice, because some firms do 
not assign individuals to specific business lines. However, the Board 
solicited comment on whether the relevant population would be partners, 
managers, and staff of the firm's audit practice, if the firm assigns 
its professionals to specific business lines.
    Some commenters agreed with the phrase ``participate in audits'' as 
used in the proposal. One of these commenters suggested that, because 
firms have different structures, attempting to separate members of the 
engagement team based on a firm's structure could lead to less 
comparability across metrics. One firm stated that it assigns 
individuals to specific business lines, and collecting data based on 
that assigned business line would be more practical to implement versus 
the proposal's requirement to include all individuals participating in 
audits.
    Some other commenters stated that firm-level metrics should look 
only to the firm's audit practice because (i) the inclusion of other 
service lines in the metrics would impair comparability between firms 
due to the varying size and scope of non-assurance practices and (ii) 
the work of tax professionals and consultants would not improve the 
usefulness of these metrics for the purposes outlined in the Board's 
proposal. Another commenter requested clarification on how to account 
for individuals who move between audit support roles and engagement-
facing functions.
    The final definitions of ``partners,'' ``managers,'' and ``staff'' 
include the phrase, ``who participate in audits,'' as proposed. Because 
some firms do not assign partners and other professionals to a specific 
business line, the Board believes this approach is the best way to 
drive consistent reporting by firms with different organizational 
structures.
    In the proposal, the Board clarified that members of the engagement 
team who participate in audits would include every partner and manager 
who worked on any aspect of the audit, even if their involvement was 
extremely limited. The Board proposed not to provide a participation 
threshold, such as a minimum number of hours, because the Board 
believes, based on the objectives of these metrics, that the metrics 
should capture all partners, managers, and staff who participate in 
audits in any capacity. However, the Board solicited comment on whether 
the concept should include a participation threshold.
    One commenter agreed there was no need to create a minimum 
threshold for participation on the basis that it would increase the 
complexity and cost of calculating the metrics without a corresponding 
benefit. Another commenter recommended establishing a minimum threshold 
for participation because exclusion of professionals with certain firm 
roles (e.g., firm leadership, national office, or specialist line of 
service individuals with limited participation during the year in any 
specific engagement) would not reduce the reliability of the metric. 
This commenter further recommended creating a minimum threshold for 
purposes of firm-level metrics, such as individuals who spent more than 
10% of their time participating on audit engagements, and engagement-
level metrics (e.g., similar to the concept of core engagement team). 
This commenter and another commenter recommended the additional 
threshold as optional for firms to use due to cost-benefit 
considerations, particularly for smaller firms, and should only be 
considered if additional thresholds allow for simpler aggregation or 
preparation of the data.
    The Board did not adopt additional thresholds to be used for firm-
level or engagement-level metrics, except for the concept of core 
engagement team used in certain engagement-level metrics discussed 
below. The objectives of the five metrics that use ``partners, 
managers, and staff of the firm'' are to understand the firm's 
professionals who participate in audits in totality, and the Board 
believes imposing a threshold on what counts as participation would 
defeat that objective.
(2) Partners, Managers, and Staff ``of The Firm'' (Used in Workload, 
Training Hours for Audit Personnel, Experience of Audit Personnel, 
Industry Experience, and Retention of Audit Personnel)
    Because firm-level metrics provide information about the firm, in 
calculating some firm-level metrics, the Board proposed to include 
partners, managers, and staff ``of the firm,'' which refers to 
individuals participating in audits who work for the firm or work under 
the firm's direction and control and function as the firm's employees 
(e.g., secondees and contractors), regardless of whether the audits are 
performed under PCAOB standards or other auditing standards.\98\ The 
Board believes including individuals in the firm-level metrics who 
participate on any firm audit is appropriate because these metrics 
would provide information about the firm and not about specific 
engagements (for example, in the area of firm-level industry 
experience, which would be relevant across a firm's entire audit 
practice). The Board added a new section to Part III, Terminology in 
Form FM to clarify the meaning of these phrases. The Board also 
clarified that participation in audits means any involvement 
(including, for example, consultation on specific matters), and thus 
may include individuals outside the engagement team, such as national 
office personnel.
---------------------------------------------------------------------------

    \98\ This should be interpreted consistently with ``firm 
personnel,'' as defined in QC 1000.A5.
---------------------------------------------------------------------------

b. Engagement Team (Used in Partner and Manager Involvement)
    The Board proposed to provide information about partners and 
managers on the engagement team, a term defined in AS 2101, Audit 
Planning.\99\ The Board believes it is

[[Page 99990]]

appropriate to provide metrics related specifically to the engagement 
team because this would provide investors and other stakeholders with 
relevant information related to the audit as a whole, who perform audit 
procedures on the audit or assist in planning or supervising the audit.
---------------------------------------------------------------------------

    \99\ The ``engagement team'' is defined in AS 2101.A3 [as 
adopted by the Board in Planning and Supervision of Audits Involving 
Other Auditors and Dividing Responsibility for the Audit with 
Another Accounting Firm, PCAOB Rel. No. 2022-002 (June 21, 2022), to 
take effect with respect to audits of fiscal years ending on or 
after December 15, 2024] as follows (footnotes omitted):
    .A3 Engagement team--
    a. Engagement team includes:
    1. Partners, principals, and shareholders of, and accountants 
and other professional staff employed or engaged by, the lead 
auditor or other accounting firms who perform audit procedures on an 
audit or assist the engagement partner in fulfilling his or her 
planning or supervisory responsibilities on the audit pursuant to 
this standard or AS 1201, Supervision of the Audit Engagement; and
    2. Specialists who, in connection with the audit, (i) are 
employed by the lead auditor or an other auditor participating in 
the audit and (ii) assist that auditor in obtaining or evaluating 
audit evidence with respect to a relevant assertion of a significant 
account or disclosure.
    b. Engagement team does not include:
    1. The engagement quality reviewer and those assisting the 
reviewer (to which AS 1220, Engagement Quality Review, applies);
    2. Partners, principals, and shareholders of, and other 
individuals employed or engaged by, another accounting firm in 
situations in which the lead auditor divides responsibility for the 
audit with the other firm under AS 1206, Dividing Responsibility for 
the Audit with Another Accounting Firm; or
    3. Engaged specialists.
---------------------------------------------------------------------------

    One commenter suggested clarifying whether ``engagement team'' for 
purposes of this rule includes internal specialists. Another commenter 
stated that the proposal appeared to provide an alternative definition 
of partners and managers on the engagement team compared to AS 2101, 
which is aligned to other PCAOB standards, and recommended providing 
clarity as to the treatment of specialists. Another commenter expressed 
concern that the definition of ``engagement team'' under AS 2101 could 
have ramifications for the calculation of engagement-level metrics, but 
did not provide any indication of what those ramifications might be.
    The Board adopted the AS 2101 term ``engagement team,'' as 
proposed. The definition of engagement team in AS 2101 includes 
specialists who, in connection with the audit, (i) are employed by the 
lead auditor or an other auditor participating in the audit and (ii) 
assist that auditor in obtaining or evaluating audit evidence with 
respect to a relevant assertion of a significant account or disclosure. 
It excludes engaged specialists.

c. Core Engagement Team (Used in Workload, Training Hours for Audit 
Personnel, Experience of Audit Personnel, and Industry 
Experience)<SUP>100 101 102 103</SUP>
---------------------------------------------------------------------------

    \100\ See AS 1210, Using the Work of an Auditor-Engaged 
Specialist.
    \101\ AS 1220 applies to those persons.
    \102\ AS 2601, Consideration of an Entity's Use of a Service 
Organization, sets forth the auditor's responsibilities with respect 
to using the work of service auditors who issue reports on the 
controls of a third-party service organization.
    \103\ Because of their roles at the company, the work of 
individuals employed or engaged by the company is not subject to 
supervision under AS 1201; they are not considered members of the 
engagement team under the adopted definition. PCAOB standards 
include requirements regarding the auditor's use of work performed 
by some of these individuals. See, e.g., AS 1105, Audit Evidence, 
Appendix A; AS 2201, An Audit of Internal Control Over Financial 
Reporting That Is Integrated With An Audit of Financial Statements; 
AS 2605, Consideration of the Internal Audit Function.
---------------------------------------------------------------------------

    For some engagement-level metrics, the Board proposed to include 
information about members of the ``core engagement team'' rather than 
the full ``engagement team,'' so as to focus the metrics on the 
individuals who make the primary decisions regarding planning and 
performance of the audit and determine the final conclusions supporting 
the auditor's opinion. With the ``core engagement team'' concept, the 
Board intends to provide more meaningful and focused data by excluding 
information about certain partners and managers with lesser 
participation. The Board also simplifies the data collection effort by 
limiting these metrics to firm personnel.
    The Board proposed that the core engagement team would include the 
engagement partner and members of the engagement team who are partners 
or employees of the firm issuing the audit report. In addition, under 
the proposal, core engagement team would include either a partner 
(excluding the engagement partner as described above) who worked ten or 
more hours on the engagement or a manager or staff who worked on the 
engagement for 40 or more hours or, if less, 2% or more of the total 
hours.\104\
---------------------------------------------------------------------------

    \104\ See below for the discussion of ``total audit hours.''
---------------------------------------------------------------------------

    Figure 3 illustrates how partners, managers, and staff used in the 
calculation of the metrics, relate to the firm, engagement team, and 
the core engagement team.

Figure 3. Relationship Between the Groups of Individuals Included in 
Metric Calculations
[GRAPHIC] [TIFF OMITTED] TN11DE24.000

    The Board solicited comments on whether the proposed definition of 
core engagement team, and the proposed participation thresholds for 
inclusion in the core engagement team, were appropriate.
    One commenter agreed that at the engagement level, metrics related 
to only the core engagement team will be more useful to investors and 
other stakeholders. Two commenters supported the proposed 10-hour 
minimum threshold for partners other than engagement partners. One of 
these

[[Page 99992]]

also supported the proposed threshold for managers and staff. This 
commenter suggested, however, that the Board includes only partners and 
employees of the lead audit firm and exclude component auditors.
    One commenter suggested aligning the definition of ``core 
engagement team'' with the ``lead auditor'' definition in amended AS 
1201 and AS 2101. Another commenter indicated that the creation of 
thresholds would conflict with other existing aspects of Form AP. This 
commenter further stated there would be challenges for firms to 
accumulate and report this data, specifically obtaining the data from 
firms that are not required to report on Form FM or Form AP and 
additional time may be needed for implementation of these metrics.
    Another commenter recommended replacing the phrase ``who worked'' 
in the proposed definition to ``who performed audit procedures'' to be 
consistent with the definitions of engagement team because this 
commenter was concerned that wording inconsistencies may cause 
confusion as to whether the same criteria apply across the various 
definitions. One commenter indicated that it is not clear on what basis 
the proposed threshold is determined and further indicated that the 
concept of core engagement team suggests that certain work in the 
engagement would be either not important or optional and recommended 
further study.
    The proposal also asked whether other individuals involved in the 
audit (e.g., individuals in the firm's national office, the EQR, 
employees of shared service centers, or individuals involved in loaned 
staff arrangements and alternative practice structures) should be 
treated differently in the metrics and, if so, how they should be 
considered in the definition of core engagement team. One commenter 
sought clarification as to whether shared service center employees 
should be included in the definition of core engagement team and 
recommended considering the nature and use of centralized services and 
how service centers continue to evolve across a changing professional 
landscape. Another commenter suggested including the EQR and 
specialists in the core engagement team but not treating them 
differently from other individuals involved in the audit. Two 
commenters recommended the definition to simply include all individuals 
who charged time to the engagement or whose cost was included within 
the engagement to minimize the cost of reporting the metrics, but one 
of the two commenters recommended excluding the quality functions such 
as the EQR to avoid any impression that they are part of the engagement 
team.
    The Board adopted the proposed definition of core engagement team 
substantially as proposed:
    1. The engagement partner and
    2. Members of the engagement team who are:
    a. Partners or employees of the registered public accounting firm 
issuing the audit report (or individuals who work under that firm's 
direction and control and function as the firm's employees); and
    b. Either of the following:
    i. A partner (excluding the engagement partner) who reported ten or 
more hours on the engagement; or
    ii. Managers and staff who reported 40 or more hours on the 
engagement or, if less, 2% or more of the total audit hours.
    As suggested by two commenters, the Board reformatted the 
presentation of core engagement team to clarify that the engagement 
partner is part of the core engagement team. In addition, the Board 
modified the descriptions of core engagement team members by 
substituting ``who reported'' for ``who worked'' to make clear that the 
basis for determining whether hours thresholds have been reached is 
time reported in the firm's timekeeping system. The Board did not align 
the definition of ``core engagement team'' with the ``lead auditor'' 
definition because including information from all of the partners and 
managers of the firm, rather than just those with significant 
participation in the engagement, would potentially skew or dilute the 
data, making the metrics less meaningful.
    As the Board proposed and the Board adopted, the term core 
engagement team excludes other auditors. As a result, there will be no 
need to obtain data from other auditors, and the definition will not 
encompass firms that are not required to file Form AP. Under current 
reporting requirements for Form AP, the lead auditor has to accumulate 
all of the hours worked on issuer engagements.\105\ While it will 
require some disaggregation of this data, the Board does not believe 
reporting the data for the engagement team for Partner and Manager 
Involvement and total audit hours for Allocation of Audit Hours will 
create a significant challenge for firms. Regarding individuals at 
shared service centers, if partners or managers employed by a shared 
service center meet the definition of core engagement team, they will 
be included. As further discussed below, the Board did not include the 
EQR in the definition of the ``core engagement team''; the core 
engagement team is a subset of the engagement team, and the EQR is not 
a part of the engagement team.
---------------------------------------------------------------------------

    \105\ See discussion of ``total audit hours'' used for Form AP 
reporting below.

d. Engagement Quality Reviewer (Used in Experience of Audit Personnel 
and Industry Experience)
    The objective of the EQR is to perform an evaluation of the 
significant judgments made by the engagement team and the related 
conclusions reached in forming the overall conclusion on the engagement 
and in preparing the engagement report, if a report is to be issued, in 
order to determine whether to provide concurring approval of 
issuance.\107\ The EQR must possess the level of knowledge and 
competence related to accounting, auditing, and financial reporting 
required to serve as the engagement partner on the engagement under 
review.\108\ While reporting on specific hours spent by the EQR or 
including the EQR's time in engagement-level metrics may have a 
negligeable quantitative impact, the Board believes reporting on EQR's 
competency for two of the engagement-level metric areas will be 
important and valuable for stakeholders.
---------------------------------------------------------------------------

    \107\ See AS 1220.02.
    \108\ See AS 1220.05.
---------------------------------------------------------------------------

    Because the EQR is not a member of the engagement team as defined 
in AS 2101, EQRs were not included in the proposed metrics when the 
proposed metrics required disclosure of the engagement team's 
information unless the disclosure of EQRs was specifically called out 
in the proposed metric area. Therefore, the Board solicited comment 
about whether EQRs should be added to any of the proposed metrics, 
separately or together with a group such as the engagement team.
    Some commenters agreed that EQRs should be excluded from the 
engagement-level metrics. These commenters indicated not to add them as 
a separate category because the EQR is not a part of the engagement 
team as defined by AS 2101 and the inclusion of the EQR would be 
inconsistent with AS 2101.
    One commenter suggested that the EQR should be included in the 
metrics but presented separately, to ensure that there is no impression 
that the EQR is not independent. One commenter recommended including 
EQR in firm-level metrics because firms generally do not assign 
partners to solely perform engagement quality reviews and firm-level 
metrics should include all partners with no requirement to allocate 
their time spent between the roles of an engagement partner and an EQR. 
Two investor-related commenters generally supported including EQR hours 
in the metrics. Another commenter questioned the rationale for not 
including metrics relating specifically to engagement quality 
reviewers, despite the fact that they are not part of the engagement 
team.
    In the final requirements, EQRs are included in the two experience-
related metrics (Experience of Audit Personnel and Industry 
Experience), where the Board believes that the information would be 
significant to users. EQRs are not included in other metrics, primarily 
due to their quantitatively insignificant impact on the metrics and to 
avoid any confusion regarding whether they are part of the engagement 
team. For metrics that depend on total audit hours (i.e., Partner and 
Manager Involvement and Allocation of Audit Hours), this approach also 
aligns with the reporting required for purposes of Form AP, from which 
EQRs are excluded.

ii. Total Audit Hours (Used in Partner and Manager Involvement and 
Allocation of Audit Hours)

    For several metric areas, the Board proposed to use ``total audit 
hours,'' which would be the same as the hours used to compute the 
extent of participation in an audit of other accounting firms in Form 
AP.\109\ Total audit hours include hours attributable to: (1) the 
financial statement audit; (2) reviews pursuant to AS 4105, Reviews of 
Interim Financial Information; and (3) the audit of ICFR pursuant to AS 
2201.\110\
---------------------------------------------------------------------------

    \109\ See Part IV of Form AP.
    \110\ ``Total audit hours'' [as amended and adopted by the Board 
in PCAOB Rel. No. 2024-005, to take effect on December 15, 2025] 
exclude the hours incurred by: (1) the engagement quality reviewer; 
(2) specialists engaged, not employed, by the firm; (3) accounting 
firms in performing the audit of entities in which the issuer has an 
investment that is accounted for using the equity method; (4) 
internal auditors, other company personne
