SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-106372; File No. PCAOB-2026-01]


Public Company Accounting Oversight Board; Notice of Filing of 
Proposed Rules on Amendments to QC 1000, A Firm's System of Quality 
Control, and Related Rule and Forms

September 15, 2026.
    Pursuant to section 107(b) of the Sarbanes-Oxley Act of 2002 (the 
``Act''), notice is hereby given that on September 10, 2026, the Public 
Company Accounting Oversight Board (the ``Board'' or the ``PCAOB'') 
filed with the Securities and Exchange Commission (the ``Commission'' 
or the ``SEC'') the proposed rules described in items I and II below, 
which items have been prepared by the Board. On September 14, 2026, the 
Board filed with the Commission a technical correction to one of the 
proposed rules. 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 September 9, 2026, the Board adopted proposed rule amendments to 
QC 1000, A Firm's System of Quality Control, related amendments to 
PCAOB Rule 2203A, PCAOB forms, and technical amendments to AS 2101, 
Audit Planning. (collectively, the ``proposed rules''). On September 
11, 2026, the Board adopted a technical correction to the proposed rule 
amendments to QC 1000. The text of the proposed rules appears in 
Exhibit A to the SEC Filing Form 19b-4 and is available on the Board's 
website at <a href="https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-057">https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-057</a>.

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, to the extent necessary, the Board is requesting that the 
Commission approve the proposed rules pursuant to section 103(a)(3)(C) 
of the 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 adopted QC 1000, A Firm's System of Quality Control (``QC 
1000''), on May 13, 2024,\1\ to lead registered public accounting firms 
(``firms'') to significantly improve their quality control (``QC'') 
systems. The Board believes that, as firms prepare for the effective 
date of QC 1000, many such improvements have been and will continue to 
be implemented as firms develop more rigorous QC systems. The Board's 
experience during the implementation period led us, however, to 
consider whether the new standard imposes costs that may not be 
necessary for us to achieve the Board's regulatory goals and, 
relatedly, whether there were certain aspects of QC 1000 that could be 
brought into closer alignment with other audit firm quality management 
standards.\2\
---------------------------------------------------------------------------

    \1\ 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 1000 2024 adopting release'').
    \2\ See International Standard on Quality Management (``ISQM'') 
1, Quality Management for Firms that Perform Audits or Reviews of 
Financial Statements, or Other Assurance or Related Services 
Engagements (``ISQM 1''), issued by the International Auditing and 
Assurance Standards Board; Statement on Quality Management Standards 
(``SQMS'') No. 1, A Firm's System of Quality Management (``SQMS 
1''), issued by the Auditing Standards Board of the American 
Institute of CPAs.
---------------------------------------------------------------------------

    The Board adopted amendments to QC 1000 that it believes address 
concerns regarding the implementation challenges identified by firms 
and better align certain provisions with other quality management 
standards. These amendments are designed to reduce compliance costs 
while maintaining the investor protection benefits of QC 1000.
    The principal amendments the Board adopted:
    <bullet> Rescind the ``design-only'' requirement so that QC 1000 
imposes requirements only on firms that are required to comply with 
applicable professional and legal requirements with respect to any 
``engagement'' as defined in QC 1000 (QC 1000.06 and .07d);
    <bullet> Provide increased flexibility in filling certain specified 
roles in the QC system by permitting roles to be assigned to non-firm 
personnel and divided among multiple individuals (QC 1000.12);
    <bullet> Rescind the requirement to have an External QC Function 
(``EQCF'') (QC 1000.28);
    <bullet> Narrow and simplify communication requirements relating to 
metrics that the firm communicates to external parties about its audit 
practice, firm personnel, or engagements (QC 1000.53e);
    <bullet> With respect to identified engagement deficiencies, 
require evaluation of whether similar engagement deficiencies exist on 
other engagements only if the identified deficiency resulted or could 
result in (i) a failure to obtain sufficient appropriate evidence to 
support the conclusion reached on an engagement or (ii) an 
inappropriate overall conclusion on the subject matter of an engagement 
(QC 1000.68d);
    <bullet> Revise the definition of QC deficiency to make clear that, 
when firms have implemented more than one quality response to address 
the same quality risk, they can take those other quality responses 
(e.g., compensating responses) into account when determining whether a 
QC deficiency exists (QC 1000.A8);
    <bullet> Allow firms to select the date as of which they annually 
evaluate the effectiveness of their QC system, rather than requiring 
firms to evaluate as of September 30 (QC 1000.77);
    <bullet> Revise the QC system evaluation conclusions to align more 
closely with the conclusions in other quality management standards, 
while retaining a structured process, including specified factors for 
consideration, to guide the evaluation (QC 1000.77 and .78); and
    <bullet> Simplify the requirements for retention of QC system 
documentation and abbreviate the retention period from seven to five 
years (QC 1000.84 and .86).
    Additional amendments the Board adopted, including conforming 
amendments, are discussed below.
    Several of the amendments the Board adopted bring QC 1000 into 
closer alignment with other quality management standards, both 
internationally and in the United States. However, differences remain 
in areas where the Board continues to believe that alternative or 
incremental provisions of QC 1000 better address its legal and 
regulatory environment, the needs and priorities of the Board's 
stakeholders, and the Board's statutory mandate of protecting investors 
and the public interest.
    QC 1000 and the related amendments to PCAOB standards, rules, and 
forms adopted in 2024 will take effect on December 15, 2026. If 
approved by the

[[Page 59355]]

SEC, the amendments to QC 1000 that the Board adopted and the related 
amendments to a PCAOB rule and PCAOB forms will also take effect on 
December 15, 2026.
    The proposed rules also include technical amendments to AS 2101, 
Audit Planning, to remove references to an auditing standard that was 
rescinded by another rulemaking.\3\ The Board adopted these amendments 
as final due to their technical nature, and the Board did not seek 
public comment on these amendments. These amendments will be effective 
upon SEC approval.

Audit and Amendments to PCAOB Standards, PCAOB Rel. No. 2024-004 
(May 13, 2024) (rescinding AS 1015, Due Professional Care in the 
Performance of Work).
---------------------------------------------------------------------------

(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 Rule Change Received 
From Members, Participants, or Others

    The Board released proposed rule amendments for public comment on 
June 9, 2026, in its release titled Supplemental Request for Comment: 
Proposed Amendments to QC 1000, A Firm's System of Quality Control, and 
Related Rule and Forms, PCAOB Release No. 2026-002. The Board received 
25 comment letters in response to that supplemental request for 
comment. See Comment Letters for Docket 057, <a href="https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-057/comment-letters">https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-057/comment-letters</a>. The 
Board also received 26 comment letters in response to a request for 
public comment on the PCAOB strategic priorities, identified at 
footnote 12 below, and 4 comment letters in response to a request for 
public comment on PCAOB standard setting, identified at footnote 289 
below, and 1 comment letter in response to a request for public comment 
on the Draft 2026-2030 Strategic Plan Goals and Objective, identified 
at footnote 300 below, which all raised comments specifically to QC 
1000, among other things. See Comment Letters on the PCAOB website 
available at <a href="https://pcaobus.org/about/strategic-plan-budget/public-comments-on-pcaob-strategic-priorities">https://pcaobus.org/about/strategic-plan-budget/public-comments-on-pcaob-strategic-priorities</a>, <a href="https://pcaobus.org/oversight/standards/standard-setting-research-projects/agenda-consultation--request-for-public-comment-on-pcaob-standard-setting">https://pcaobus.org/oversight/standards/standard-setting-research-projects/agenda-consultation--request-for-public-comment-on-pcaob-standard-setting</a>, and <a href="https://pcaobus.org/about/strategic-plan-budget/public-comments-on-goals-and-objectives-for-pcaob-strategic-plan-2026-2030">https://pcaobus.org/about/strategic-plan-budget/public-comments-on-goals-and-objectives-for-pcaob-strategic-plan-2026-2030</a>, respectively. The Board 
has carefully considered all comments received. The Board's responses 
to the comments received, including revisions to the proposed rule 
amendments, are discussed below.

Background

    This section presents background information on this rulemaking, 
including recent rulemaking history and staff implementation support 
efforts since SEC approval of QC 1000 in September 2024.
    Recent Rulemaking History
    On May 13, 2024, the Board adopted QC 1000 and related amendments. 
They were approved by the SEC on September 9, 2024, with an effective 
date of December 15, 2025.\4\
---------------------------------------------------------------------------

    \4\ For more details regarding the rulemaking history of QC 
1000, see Rulemaking Docket No. 046 on the Board's website, 
available at <a href="https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-046-quality-control">https://pcaobus.org/about/rules-rulemaking/rulemaking-dockets/docket-046-quality-control</a>; see also Public Company

Firm's System of Quality Control and Related Amendments to PCAOB 
Standards, Rules, and Forms, SEC Rel. No. 34-100968 (Sept. 9, 2024).
---------------------------------------------------------------------------

    On August 28, 2025, to provide firms with additional time for 
implementation, the Board proposed to delay the effective date of QC 
1000 and the related amendments to December 15, 2026, and that 
postponement became immediately effective.\5\ The SEC received 15 
comment letters in response to its notice regarding the 
postponement.\6\ Commenters generally supported providing additional 
implementation time but raised concerns regarding certain provisions of 
QC 1000 that they viewed as more prescriptive than other quality 
management standards and as creating unnecessary operational complexity 
and cost.
---------------------------------------------------------------------------

page, available at <a href="https://www.sec.gov/comments/pcaob-2025-01/pcaob202501.htm">https://www.sec.gov/comments/pcaob-2025-01/pcaob202501.htm</a>.
---------------------------------------------------------------------------

    On July 23, 2025, and March 20, 2026, the PCAOB received letters 
from a firm-related group regarding implementation of QC 1000 and 
related implementation challenges.\7\

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

    On March 31, 2026, the Board issued a request for public comment on 
the PCAOB's strategic priorities, including future standard-setting 
activity.\8\ Several commenters provided observations regarding QC 
1000.\9\ The comments relating to QC 1000 were generally consistent 
with themes raised in comment letters submitted to the PCAOB and SEC in 
connection with the extension of the effective date of QC 1000. Most 
commenters urged the Board to adopt or align more closely with ISQM 1, 
suggesting it may better support global implementation, while 
emphasizing that differences in structure, terminology, and 
prescriptive requirements in QC 1000 create operational challenges, 
limit firm judgment, and increase complexity for global firms.
---------------------------------------------------------------------------

PCAOB Rel. No. 2026-001 (Mar. 31, 2026).

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

    After considering feedback and information obtained through 
implementation support efforts,\10\ on June 9, 2026, the Board issued a 
supplemental request for comment on potential targeted amendments to 
certain provisions of QC 1000 and related amendments to the QC 
reporting rule and PCAOB forms.\11\ The Board received 26 comment 
letters.\12\

[[Page 59356]]

Commenters included firms and firm-related groups, investor-related 
groups, and others. Firms, firm-related groups, and most other 
commenters generally supported the Board's objective of making targeted 
amendments to QC 1000 and most of the proposed amendments, particularly 
those intended to increase flexibility, improve operability, reduce 
unnecessary compliance burdens, and better align QC 1000 with other 
quality management standards.\13\ One investor-related group did not 
support the proposed amendments overall because of the proposed 
rescission of the EQCF requirement.\14\ Other investor-related groups 
generally supported the proposed amendments that reduce compliance 
costs without reducing audit quality, but opposed the removal of the 
EQCF requirement, emphasizing the importance of independent oversight 
and investor protection, and other amendments they viewed as weakening 
investor-protection-focused provisions of QC 1000.\15\ Many commenters, 
particularly firms and firm-related groups, also requested 
implementation guidance and clarification in certain areas discussed 
below.\16\

support efforts, including implementation guidance, workshops, 
stakeholder outreach, and feedback received from firms and other 
stakeholders regarding QC 1000 implementation.

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

    The Board considered all comments received on the supplemental 
request for comment. As discussed below, the Board is adopting the 
proposed amendments to QC 1000, with certain modifications.

Implementation Support Efforts

    Since SEC approval of QC 1000, PCAOB staff have supported 
implementation through guidance, workshops, outreach activities, and 
engagement with stakeholders, which provided insight into 
implementation progress, challenges, and questions and informed the 
Board's consideration of the proposed amendments.\17\ Additionally, as 
part of inspection outreach activities, the Board obtained feedback on 
the progress made by firms in implementing QC 1000 in their QC 
systems.\18\
---------------------------------------------------------------------------

    \17\ See PCAOB, Quality Control--Implementation Resources, 
available at <a href="https://pcaobus.org/oversight/standards/implementation-resources-PCAOB-standards-rules/quality-control">https://pcaobus.org/oversight/standards/implementation-resources-PCAOB-standards-rules/quality-control</a>, which includes 
staff guidance and other materials issued to support implementation 
of QC1000 and the related amendments.
    \18\ See section titled ``Need'' under ``Economic 
Considerations'' below for additional information on data received 
through these inspection outreach activities.
---------------------------------------------------------------------------

    As part of staff implementation support efforts, the PCAOB staff 
released QC 1000 Questions and Answers (``QC 1000 Q&As'') in August 
2026.\19\ The QC 1000 Q&As provide technical guidance on various 
aspects of QC 1000, including roles and responsibilities, evaluation 
and reporting, documentation, and other areas of designing, 
implementing, operating, and evaluating a firm's QC system. The QC 1000 
Q&As were developed in response to questions and requests for 
clarification received from firms through staff implementation support 
efforts and are intended to reduce uncertainty and support firms' 
implementation of the standard.
---------------------------------------------------------------------------

    \19\ See QC 1000 Questions and Answers, available at <a href="https://pcaobus.org/oversight//setting-research-projects/quality-control/qc-1000-questions-and-answers">https://pcaobus.org/oversight//setting-research-projects/quality-control/qc-1000-questions-and-answers</a>.
---------------------------------------------------------------------------

    The QC 1000 Q&As do not address the specific topics that are the 
subject of the amendments to QC 1000 that the Board adopted, but they 
do address some questions and clarification requests on other topics 
that were included in comment letters submitted in response to the 
supplemental request for comment. As implementation continues, 
additional guidance, including updates to the QC 1000 Q&As, may be 
issued to help address other areas identified by commenters or through 
staff implementation support efforts.

Amendments to QC 1000, PCAOB Rule 2203A, and PCAOB Form QC

    This section describes the requirements of QC 1000, Rule 2203A, and 
Form QC that the Board amended.

Requirement To Design, Implement, and Operate a QC System

    As originally adopted, QC 1000.06 requires all firms to design a QC 
system that complies with the standard, regardless of whether the firm 
is subject to applicable professional and legal requirements with 
respect to an engagement as defined in QC 1000. As explained in the 
supplemental request for comment, the Board understands that this 
``design-only'' requirement would impose costs on firms that do not 
perform engagements requiring registration under the Sarbanes-Oxley Act 
of 2002 (``Sarbanes-Oxley'') \20\ or PCAOB rules \21\ without 
commensurate benefits for investors and the public. Therefore, the 
Board proposed to eliminate the requirement and sought comment on 
potential alternatives, as well as any circumstances that potentially 
could trigger a design requirement. As proposed in the supplemental 
request for comment, paragraphs .05 through .07 of QC 1000 would be 
revised to eliminate the separate obligation to design a QC system and 
would maintain unchanged the obligation to design, implement, and 
operate a QC system in compliance with QC 1000 when a firm is subject 
to applicable professional and legal requirements with respect to any 
of the firm's engagements.
---------------------------------------------------------------------------

    \20\ See section 102(a) of Sarbanes-Oxley, 15 U.S.C. 7212(a).
    \21\ See PCAOB Rule 2100, Registration Requirements for Public 
Accounting Firms.
---------------------------------------------------------------------------

    Many commenters supported the proposal to rescind the design-only 
requirement.\22\ One commenter stated that they did not object to 
rescinding the design-only requirement when a firm neither performs nor 
intends to perform PCAOB engagements.\23\ One of the commenters 
supporting rescission stated that it did not believe registered firms 
should be required to comply with PCAOB standards until the firm 
undertakes an engagement requiring compliance with those standards and 
that the design-only requirement was inconsistent with the text of 
Sarbanes-Oxley.\24\ Commenters that addressed the question of whether 
the Board should adopt an alternative design-only requirement generally 
did not support such a requirement.\25\
---------------------------------------------------------------------------

    \22\ See comment letters from AAA, Baker Tilly, BDO, CAQ, Crowe, 
Deloitte, GT, KPMG, Kramer, MIAG, PICPA, PwC, and RSM. But see 
comment letters from ICGN and Spitters. One commenter expressed 
support for eliminating the ``design-only reporting requirement,'' 
described as the ``requirement for firms to report once a quality 
control system has merely been designed.'' See comment letter from 
VSCPA.
    \23\ See comment letter from CFA.
    \24\ See comment letter from RSM.
    \25\ See comment letters from AAA, BDO, GT, KPMG, Kramer, and 
PICPA.
---------------------------------------------------------------------------

    However, one commenter stated support for a QC design requirement 
that included effective operation of a system of quality management 
under relevant standards for the jurisdiction in which the firm 
operates, such as ISQM 1 or SQMS 1.\26\ This commenter noted that, in 
practice, registered firms would already maintain some form of a system 
of quality management to support their

[[Page 59357]]

PCAOB registration.\27\ The Board does not believe QC 1000 should 
explicitly require compliance with rules of local jurisdictions, as 
PCAOB standards generally do not impose such requirements. Another 
commenter noted that, although some registered firms do not conduct 
audits, that fact does not necessarily signify the need for an 
exemption from standard best practices or audit quality requirements; 
such firms should be subject to QC 1000 on the level of preparedness or 
some QC regime that parallels QC 1000 in its design, implementation, 
and operation.\28\ The Board does not believe that the suggestion to 
base a design-only requirement on a level of preparedness or a system 
paralleling QC 1000 is workable because it is too vague as to the 
requirements that would apply to firms not performing PCAOB 
engagements.
---------------------------------------------------------------------------

    \26\ See comment letter from RSM.
    \27\ See id.
    \28\ See comment letter from Spitters.
---------------------------------------------------------------------------

    Commenters raised concerns over the costs of the design-only 
requirement in relation to the benefits.\29\ One commenter stated that 
the requirement would have resulted in unnecessary costs of compliance 
without commensurate benefits.\30\ Another commenter similarly stated 
that requiring firms not performing PCAOB engagements to comply with 
the design-only requirement did not provide a commensurate benefit to 
investor protection, as such firms do not present risk to U.S. capital 
markets.\31\ Another commenter stated that requiring firms to build 
compliance infrastructure for work they may never undertake imposes 
cost without a corresponding investor benefit.\32\ Another commenter 
observed that, because firms performing engagements would be fully 
subject to the requirement to design, implement, and operate a QC 1000-
compliant system, rescinding the requirement for firms not performing 
such work would preserve the Board's objective of promoting high-
quality audits, while reducing unnecessary burdens for those firms.\33\ 
Another commenter stated that, while the value to the public of the 
design-only requirement was unclear, the costs would be real in the 
form of training costs, consulting costs, and professional time.\34\ 
Other commenters noted the limited benefits of the requirement for 
investors, stating that rescission would not diminish investor 
protection \35\ or introduce any risk to investors,\36\ or that 
retaining the requirement would not help ensure improved audit 
quality.\37\

    Two commenters also raised concerns about requiring firms to 
address hypothetical situations. One of these commenters stated that it 
would be difficult for a firm not subject to applicable professional 
and legal requirements with respect to any engagement to design a QC 
system based on hypothetical circumstances.\38\ The second commenter 
stated that such a firm's QC system ``would be hypothetical at best and 
would likely become obsolete over time as practice conditions change, 
leading to the false pretense that [the firm is] in a position to 
immediately implement these standards.'' \39\
---------------------------------------------------------------------------

    \38\ See comment letter from AAA.
    \39\ See comment letter from PICPA.
---------------------------------------------------------------------------

    The Board is rescinding the design-only requirement and adopting 
paragraphs .05 through .07 as proposed.\40\ The Board believes 
rescinding the design-only requirement will reduce costs for firms 
without any significant detriment to audit quality.
---------------------------------------------------------------------------

    \40\ As noted in the supplemental request for comment, the Board 
does not believe that this action would violate the mandate in 
section 103(a)(2)(B) of Sarbanes-Oxley, 15 U.S.C. 7213(a)(2)(B), to 
adopt requirements ``for every registered public accounting firm'' 
that address certain enumerated areas in ``the quality control 
standards that [the PCAOB] adopts with respect to the issuance of 
audit reports.'' Under the Board's approach, QC 1000 will apply to 
every firm with respect to the issuance of ``audit reports'' (which 
are limited under Sarbanes-Oxley to those relating to audits of 
issuers and broker-dealers).
---------------------------------------------------------------------------

    As confirmed by commenter feedback, implementing the design-only 
requirement has proven more difficult and costly than originally 
anticipated. The requirement may compel some firms that have no 
intention of performing PCAOB engagements in the foreseeable future to 
design a QC 1000-compliant system, perhaps based on hypothetical 
circumstances. As described in the supplemental request for comment, 
the Board believes that the design-only requirement may have 
contributed to an increase in withdrawals from registration by firms 
that are not performing engagements. Although the impact of such 
activity on the marketplace (discussed below in the economic analysis) 
may be limited, the Board believes investors and the public interest 
are better served by incentivizing firms to register and consider 
seeking PCAOB engagements, thereby promoting competition.\41\
---------------------------------------------------------------------------

    \41\ As noted in the supplemental request for comment, some 
firms may register with the Board to perform activities not subject 
to the PCAOB's jurisdiction. See, e.g., Guiding and Establishing 
National Innovation for U.S. Stablecoins Act, Pub. L. 119-27 (July 
18, 2025), section 4(a)(3)(A), 12 U.S.C. 5903(a)(3)(A) (requiring 
month-end reports of permitted payment stablecoin issuers to be 
examined by a PCAOB-registered firm).
---------------------------------------------------------------------------

    In the Board's view, rescission of the design-only requirement 
would entail foregoing the benefits associated with greater 
preparedness of firms to take on a PCAOB engagement for the first time. 
The Board believes this benefit to be modest, as any firm that actually 
takes on such an engagement will have become subject to the requirement 
to design, implement, and operate a QC 1000 system.\42\ In any event, 
and as noted by one commenter, registered firms that do not perform 
PCAOB engagements are generally well-positioned to implement QC 1000 if 
or when required to do so.\43\ This is so because most such firms, as 
some commenters observed, are generally either non-U.S. firms subject 
to international auditing standards or U.S.-based firms that conduct 
private company audits under the standards of the Auditing Standards 
Board of the American Institute of CPAs (``AICPA''); as such, those 
firms would be subject to ISQM 1 or SQMS 1, which both share a common 
basic structure with QC 1000.\44\ Finally, as stated in the 
supplemental request for comment, the investor protection concerns 
encompassed by the Board's statutory mandate are reduced where a firm 
is not performing PCAOB engagements.
---------------------------------------------------------------------------

    \42\ Firms could still choose to design (and for that matter, 
implement and operate) a QC system that complies with QC 1000. Firms 
may choose to do so if, for example, they are planning to bid for a 
PCAOB engagement, are taking on work on other firms' engagements 
that could potentially constitute a substantial role, or otherwise 
want to put themselves in a position to implement and operate a QC 
1000-compliant system on short notice.
    \43\ See comment letter from KPMG.
    \44\ See comment letters from AAA, CAQ, KPMG, and PwC.
---------------------------------------------------------------------------

    Based on the above considerations, the Board decided not to adopt 
any of the design-only alternatives discussed in the supplemental 
request for comment.
    The Board also considered whether to include provisions in QC 1000 
specifying an earlier trigger for the requirement to design, implement, 
and operate a QC 1000-compliant system under QC 1000.06-.07. In this 
regard, one commenter encouraged the Board to consider whether 
compliance with QC 1000 after its December 15, 2026 effective date 
could be tied to an

[[Page 59358]]

established evaluation period and measurement date rather than a 
specific triggering event.\45\ The same commenter suggested that under 
such an approach, a firm would determine at the beginning of its 
selected evaluation cycle whether it is required to comply with QC 1000 
during that period.\46\ Another commenter stated that a firm must have 
``an appropriately designed and operational QC system before accepting 
or commencing PCAOB audit work.'' \47\ Another commenter suggested that 
``a QC system must be in place prior to a firm tendering an offer for a 
public company audit and/or getting registered.'' \48\ Another 
commenter requested that the Board specify an earlier trigger--for 
example, when a firm bids for or is appointed to issuer or broker-
dealer work--by which time a compliant QC system must be designed and 
operating, well in advance of the firm commencing that work.\49\
---------------------------------------------------------------------------

    \45\ See comment letter from BDO.
    \46\ See id.
    \47\ See comment letter from MIAG.
    \48\ See comment letter from ICGN.
    \49\ See comment letter from CFA.
---------------------------------------------------------------------------

    While an earlier trigger may promote readiness by firms to commence 
PCAOB engagements, the Board expects that the effort required to 
design, implement, and operate a QC 1000-compliant system may vary 
significantly across firms. That variation could arise from several 
different factors, including the status of their existing QC systems, 
the nature of their assurance practice (if any), the experience of 
their personnel, and the nature of their governance systems, operating 
processes, and technology, among other things. The Board also 
understands that some firms may pursue engagements for issuers and 
broker-dealers months, or even years, before these firms are awarded 
and commence such work. In light of these considerations, it may not be 
necessary in all circumstances for a firm to have a QC system that 
fully complies with QC 1000 before it pursues an issuer or broker-
dealer engagement that might not be awarded to it or that might not 
commence for a significant period of time. Therefore, the Board 
believes that requiring firms to design, implement, and operate a QC 
1000-compliant system when a firm becomes subject to applicable 
professional and legal requirements with respect to any engagement is 
appropriate, and an earlier trigger is not warranted.

Roles and Responsibilities

1. Assignment of Roles and Responsibilities
    As originally adopted, QC 1000 requires that the operational roles 
and responsibilities specified in paragraph .12 be assigned only to 
``firm personnel.'' \50\ The note to paragraph .12 provides that 
responsibility for the roles in subparagraphs a-c cannot be shared and 
is required to be assigned to only one individual, to reinforce that 
the individual assigned to a specified role would be responsible and 
accountable for the role.
---------------------------------------------------------------------------

    \50\ See QC 1000.A5.
---------------------------------------------------------------------------

    The Board proposed amendments to paragraph .12 to allow flexibility 
in assigning the specified roles and responsibilities to any individual 
(whether firm personnel or an ``other participant'' \51\), rather than 
limiting those roles and responsibilities to firm personnel. In 
connection with that change, the Board proposed a new footnote 5A to 
paragraph .12 to clarify that such individuals would be ``associated 
persons'' of the firm. As the Board explained in the supplemental 
request for comment, any individual who was not already an associated 
person would become an associated person by virtue of that 
assignment.\52\ The proposed amendments would align with ISQM 1 and 
SQMS 1 by permitting any qualified individual to fill the specified QC 
system roles.
---------------------------------------------------------------------------

    \51\ See QC 1000.A7.
    \52\ See PCAOB Rule 1001(p)(i).
---------------------------------------------------------------------------

    To preserve the accountability and responsibility objectives of 
paragraph .12, the Board also proposed an amendment to emphasize that 
the individuals assigned specific roles understand and be accountable 
for their roles and responsibilities. The Board also proposed an 
amendment to the note to paragraph .12 to allow firms to divide the 
responsibilities of a role specified in paragraph .12 among multiple 
individuals. The proposed amendments align with ISQM 1 and SQMS 1.
    Commenters generally supported allowing the specified roles to be 
assigned to other participants and divided among multiple 
individuals.\53\ Many commenters indicated the amendments would promote 
audit quality, for example, by enabling the firm to place the most 
experienced and qualified individuals in those roles.\54\ Several 
commenters also supported allowing firms the flexibility to assign 
roles and responsibilities to multiple individuals based on their 
specialized expertise and capacity, including within their existing 
structures, while maintaining accountability.\55\ Several commenters 
stated that the proposed amendments to paragraph .12 were sufficiently 
clear and appropriate.\56\

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

    A commenter stated that the proposed amendments would be especially 
helpful to firms that issued audit reports with respect to less than 
100 issuers.\57\ Another commenter supported the addition of footnote 
5A, which clarifies that an individual assigned operational 
responsibility for any of the roles in paragraph .12 would become an 
associated person of the firm by virtue of that assignment.\58\ One 
commenter recommended retaining clear firm-level accountability and 
documentation requirements to avoid diffusion of responsibility.\59\ 
Another commenter recommended the final standard require clear 
identification of those ultimately responsible for the QC system and 
key QC areas; this commenter further suggested that the PCAOB encourage 
firms to consider the firms' retirees for QC system roles, as such 
individuals would provide valuable experience.\60\

    \57\ See comment letter from Kramer.
    \58\ See comment letter from PICPA.
    \59\ See comment letter from SCCG.
    \60\ See comment letter from MIAG.
---------------------------------------------------------------------------

    One commenter did not support assigning roles to individuals 
outside the firm because individuals outside the firm may have 
conflicting interests, and they cannot provide the day-to-day ownership 
the roles require.\61\ The same commenter stated that there remains a 
need for an ultimate point of accountability and there needs to be 
assurance that accountability is not diffused when responsibilities are 
divided.\62\ Further, the commenter requested that whenever a QC role 
is divided among multiple individuals, the firm's reporting to the 
PCAOB identify (1) who holds ultimate responsibility and accountability 
for the QC system as a whole; (2) who is accountable for each function, 
such as ethics, independence, monitoring, and remediation; and (3) the 
scope of each individual's assigned responsibilities, so that no part 
of any role is left unassigned.\63\

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

    As to the question of whether the flexibility afforded by the 
proposed amendments should be available only

[[Page 59359]]

on a scaled basis to certain firms, many commenters generally favored 
applying the amendments to all firms.\64\ Several of these commenters 
emphasized that the flexibility the proposed amendments would offer is 
important for firms of all sizes, although for reasons that may differ 
between larger and smaller firms.\65\ One commenter said such 
flexibility appears appropriate regardless of firm size, while noting 
that larger firms may be better equipped to operate under a more 
restrictive and specialized set of requirements.\66\ Another commenter 
stated they would not be opposed to a limited degree of scaling these 
requirements to address cost considerations for small and large 
firms.\67\

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

    After consideration of the comments received, the Board is adopting 
these amendments as proposed. The Board believes the flexibility 
afforded by the amendments should be available to all firms rather than 
on a scaled basis, because audit quality is enhanced when firms can 
assign the specified roles and responsibilities to the most qualified 
individuals, whether or not they are firm personnel. In the Board's 
view, the amendments will expand the pool of individuals with the 
requisite experience, competence, authority, and time to serve in 
specified roles. For example, a firm may improve its QC system and 
overall audit quality by assigning to one individual operational 
responsibility for ethics and to another individual operational 
responsibility for independence, where each individual has specific 
expertise in their respective area.
    In response to commenters that recommended clear firm-level 
accountability and documentation when roles are divided, paragraph .27 
requires a firm to establish and maintain clear lines of responsibility 
and supervision within the QC system, including defining authorities, 
responsibilities, accountabilities, and supervisory and reporting lines 
for roles within the firm up to and including the principal executive 
officer(s). Additionally, paragraph .82a requires the firm to document 
the lines of responsibility and supervision required by paragraph .27. 
In response to a commenter's call for specific reporting to the PCAOB 
about divided roles, the Board notes that Item 3.1 of Form QC requires 
firms to disclose (1) who holds ultimate responsibility and 
accountability for the QC system as a whole and (2) which individual or 
individuals have operational responsibility for ethics and independence 
and for monitoring and remediation. Although the specific scope of each 
individual's assigned responsibilities would not be reported, that 
information must be documented under paragraph .82a and would be 
available to the PCAOB in connection with its oversight activities, 
including inspections.\68\
---------------------------------------------------------------------------

    \68\ See PCAOB Rule 4000(b), General.
---------------------------------------------------------------------------

2. Responsibilities for Roles With Operational Responsibility
    To align with the amendments to QC 1000.12, the Board proposed 
conforming amendments to paragraphs .15-.17 that would acknowledge the 
possibility that multiple individuals could share the specified roles 
and clarify that such individuals' obligations would be limited to the 
scope of their assigned responsibilities.
    In addition, the Board proposed amendments to paragraph .17b(2) 
through (3) to delete the communication requirements related to major 
QC deficiencies to align with the amendments to the evaluation 
requirement in paragraph .77 discussed below.
    Commenters who addressed these amendments supported the proposed 
changes to paragraphs .15-.17 and stated they are sufficiently 
clear.\69\ Two commenters acknowledged that the conforming amendments 
are appropriately aligned with the revisions to paragraph .12.\70\ One 
commenter stated the conforming amendments reinforce a more principles-
based approach \71\ and another commenter stated the conforming 
amendments increase flexibility.\72\ After consideration of the 
comments received, the Board is adopting these conforming amendments as 
proposed.

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

External QC Function

    As originally adopted, paragraph .28 of QC 1000 includes a 
specified quality response that requires firms with a larger PCAOB 
audit practice \73\ to incorporate into their governance structure an 
EQCF for the QC system composed of one or more persons who:
---------------------------------------------------------------------------

    \73\ Firms with a larger PCAOB audit practice are considered 
those firms that issued audit reports for more than 100 issuers in 
the prior calendar year.
---------------------------------------------------------------------------

    <bullet> Are not partners, shareholders, members, other principals, 
or employees of the firm;
    <bullet> Do not otherwise have a commercial, familial, or other 
relationship with the firm that would interfere with the exercise of 
independent judgment with regard to matters related to the QC system; 
and
    <bullet> Have the experience, competence, authority, and time 
necessary to enable them to carry out the responsibilities assigned to 
the EQCF by the firm.
    The EQCF's responsibilities include, at a minimum, evaluating the 
significant judgments made and the related conclusions reached by the 
firm when evaluating and reporting on the effectiveness of its QC 
system.
    The Board proposed rescinding the EQCF requirement based on 
information obtained in connection with staff implementation support 
efforts and outreach discussions, which revealed that implementing this 
requirement had proven more difficult and more costly than originally 
anticipated. The Board was concerned that the potential benefits may 
not justify the potential costs of the EQCF requirement, except 
potentially for the largest U.S. global network firms.
    Many commenters expressed support for rescinding the EQCF 
requirement.\74\ Some of these commenters said rescission would allow 
firms the flexibility to utilize existing external governance 
structures to promote audit quality in a manner tailored to their 
specific circumstances.\75\ Some commenters stated that removing the 
EQCF requirement would not diminish the focus on quality because QC 
1000 advances the objectives of strengthening trust in governance, 
reinforcing accountability, and supporting a commitment to quality 
through other provisions in the standard.\76\ Other commenters offered 
support for the proposed rescission by asserting that existing 
governance structures, leadership accountability, monitoring 
activities, reporting processes, and PCAOB inspections already provide 
meaningful oversight or help promote the effective operation of the QC 
system.\77\

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

    In addition, many commenters observed that the costs associated 
with

[[Page 59360]]

the EQCF requirement, as well as any incremental benefits to audit 
quality, remain uncertain.\78\ Some commenters who supported removing 
the requirement cited significant implementation challenges and costs 
associated with identifying, recruiting, and onboarding individuals 
with the necessary expertise, independence, and availability to serve 
in the role.\79\ Other commenters pointed to additional costs, 
including obtaining liability insurance and making governance-related 
structural changes, as further reasons to support the proposed 
rescission.\80\ One commenter cautioned that rescission of the EQCF 
requirement would remove a level of assurance with respect to internal 
processes and audit quality in firms but described the requirement as 
expensive, redundant, overreaching, and unnecessary.\81\ Two commenters 
acknowledged the narrow responsibilities of an individual serving in an 
EQCF role, but asserted that the Board may have overstated the 
potential costs of the EQCF requirement by using particular benchmarks 
involving compensation of non-employee company directors to estimate 
potential costs.\82\ These commenters also suggested that the Board may 
have understated the potential benefits of the EQCF requirement by 
failing to consider the ongoing trend of private equity investing in 
accounting firms.\83\ Another commenter stated that many of the firms 
most likely to be affected already use external advisers and that the 
incremental burden of establishing the mandated function may be less 
substantial than the proposal implies.\84\ This commenter also stated 
that the Board did not have direct evidence on the cost of the EQCF to 
firms.\85\

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

    One commenter raised concerns that the size and complexity of a 
large firm's QC system would create practical constraints on the depth 
of engagement individuals serving in the EQCF role can achieve, thereby 
limiting the EQCF's overall effectiveness and value beyond the 
oversight already available through existing channels.\86\ Another 
commenter supported rescission of the EQCF requirement because its 
current form is not scalable for firms only moderately above the 100-
issuer threshold.\87\
---------------------------------------------------------------------------

    \86\ See comment letter from Deloitte.
    \87\ See comment letter from Baker Tilly.
---------------------------------------------------------------------------

    Some commenters opposed the proposed rescission of the EQCF 
requirement.\88\ Two commenters disagreed with the PCAOB's reasoning 
``that the benefits of the requirement may not justify the costs, 
except potentially for the largest U.S. global network firms.'' \89\ 
The same commenters, while acknowledging concerns related to potential 
costs, liability, and implementation, stated that some form of 
independent challenge remains a critical component of an effective QC 
system.\90\ Another commenter viewed the EQCF as essential to audit 
quality.\91\ One commenter expressed concern that rescinding the EQCF 
requirement would leave judgments about the firms' QC systems entirely 
to the firms themselves.\92\ This commenter stated the EQCF is the 
clearest structural safeguard against the commercial and network 
pressures and interests that can affect a firm's judgments regarding 
its QC system.\93\ This commenter further asserted that, as the PCAOB 
moves the focus of its audit inspections to the firm rather than the 
engagement level, and as private-equity ownership and other commercial 
pressures within the auditing profession continue to grow, retaining 
such a safeguard is particularly important.\94\

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

    Two commenters also asserted that the requirement for larger PCAOB 
audit practices to have an EQCF would be applicable to only five 
firms.\95\ However, absent rescission of the EQCF requirement, 13 
firms, based on 2025 data, would become subject to that 
requirement.\96\
---------------------------------------------------------------------------

    \95\ See comment letters from CII and MIAG.
    \96\ See footnote 401 for a list of the 13 firms.
---------------------------------------------------------------------------

    In responding to the question regarding an alternative threshold 
for the EQCF requirement, many commenters stated it was not necessary 
to impose the EQCF requirement on any firm, regardless of size or 
number of issuers audited.\97\ Some commenters did not support an 
alternative threshold (e.g., restricting the requirement only to firms 
auditing more than 500 issuers) because retaining the requirement in 
any form would not resolve the underlying concerns about operability, 
costs, availability of qualified individuals, and uncertain incremental 
benefit.\98\ Some commenters said that firms should have the 
flexibility to create governance structures that align with the nature 
and extent of their existing structure and risks of the firm.\99\

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

    One commenter stated that if the Board concludes that some relief 
is necessary, it is better to retain the EQCF requirement as adopted 
for firms auditing more than 500 issuers because it would apply to the 
five firms where nearly all U.S. public market capitalization 
sits.\100\ One commenter stated that if the current 100-issuer 
threshold were not retained, they would not oppose amending the 
threshold to firms that issued audit reports for more than 200 issuers 
during the prior calendar year, because they believe that the large 
revenue base received from those firms' issuer audit clients could 
support the incremental costs associated with the EQCF 
requirement.\101\ One commenter suggested retaining the EQCF 
requirement for firms that have accepted any form of outside 
investment, other than traditional debt financing, and operate through 
an alternative practice structure.\102\ In addition, one commenter who 
opposed removing the EQCF requirement expressed the view that smaller 
firms (under 100 audits per year) should not be exempted from robust 
and functioning alternative EQCF requirements if the PCAOB were to 
scale the provisions.\103\ Another commenter noted that, given the 
unchanged effective date of QC 1000, adopting alternative oversight 
frameworks could present implementation challenges and leave firms with 
limited time to thoughtfully design and integrate new requirements into 
their governance structures.\104\

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

    In the supplemental request for comment, the Board sought input on 
the alternative of reverting the requirement for an independent 
oversight function to that contained in the 2022 proposal. Several 
commenters did not support such an alternative.\105\ One commenter 
stated that the 2022 proposed requirement lacked sufficient clarity

[[Page 59361]]

and could create uncertainty regarding whether existing firm governance 
and oversight arrangements would satisfy such a requirement.\106\ 
Another commenter indicated that the effect or impact of adopting the 
requirement as initially proposed in 2022 could not be determined.\107\ 
One commenter did not support reverting back to the 2022 proposed 
requirement because it carried no defined duty to evaluate the firm's 
QC conclusions--the very check the EQCF was adopted to provide.\108\

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

    After consideration of the comments received, the Board is 
rescinding the EQCF requirement. Based on staff implementation support 
efforts, the Board understands that implementation of this requirement 
may have proven more difficult and costly than originally anticipated. 
The Board also acknowledges the concerns raised by commenters about the 
costs, operability, and potential limited benefit of the EQCF 
requirement, including the availability of qualified individuals to 
serve in an EQCF role, for firms of any size. In the Board's view, 
rescinding the EQCF requirement means giving up the benefits of an 
external second look. That external second look would have focused on 
the significant judgments made and related conclusions reached when 
evaluating and reporting on the effectiveness of firms' QC systems. The 
Board believes those incremental benefits are difficult to quantify and 
potentially limited. They would come from the fresh perspectives of an 
individual serving in an EQCF role, beyond the benefits already 
provided by other aspects of QC 1000. See below for further discussion 
on economic impacts.
    The Board believes that the implementation concerns apply equally 
to all firms, including those operating under alternative practice 
structures or accepting private equity investments, regardless of the 
number of issuers they audit.
    One commenter opposed the rescission, asserting that firm 
leadership should be held accountable through independent 
oversight.\109\ Further, the commenter suggested that firms might lack 
the ability to ``convince investors they can do the right thing when 
left to their own judgment.'' \110\ As designed, though, the EQCF lacks 
a mechanism or the authority to hold firm leadership accountable; the 
EQCF is not required to provide concurring approval of the firm's 
evaluation or reporting.\111\ Nor would the EQCF supplant the firm's 
judgment.

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

    Furthermore, the Board notes that the QC 1000 quality objectives 
for the governance and leadership component continue to call for (i) 
firm leadership to communicate and promote the firm's commitment to 
quality; (ii) the firm to clearly define leadership's responsibility 
for quality and hold them accountable; (iii) firm leadership to 
demonstrate a commitment to quality through actions and behaviors; (iv) 
the firm's strategic decisions and actions to be consistent with and 
support the firm's commitment to quality; and (v) resources to be 
obtained, developed, allocated, and assigned in a manner that enables 
an effective QC system and the performance of engagements in accordance 
with applicable professional and legal requirements.\112\ To achieve 
these quality objectives, firms are required to design and implement 
quality responses that are based on the related quality risks and on 
the reasons for the assessments given to the quality risks and to 
reduce to an appropriately low level the risk that quality objectives 
will not be achieved. The Board has also observed that several firms 
already incorporate external advisors into their organizational and 
governance structures and they may continue to do so as part of their 
response to the quality risks associated with these quality objectives. 
The Board has long considered firm governance and leadership to be an 
important aspect of firms' QC systems that will continue to be subject 
to oversight by the PCAOB, including as part of PCAOB inspections.

Information and Communication

    QC 1000 requires a firm to establish a quality objective that, if 
the 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 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.
    As discussed in the QC 1000 2024 adopting release, the information 
that this requirement applies to includes public communications about 
firm-level or engagement-level information, such as firm metrics and 
financial data.\113\ For example, some firms publish transparency or 
audit quality reports, either voluntarily or in response to the 
requirements of other jurisdictions, that contain data such as:
---------------------------------------------------------------------------

    \113\ See PCAOB Rel. No. 2024-005, at 186.
---------------------------------------------------------------------------

    <bullet> Revenue breakdown by service line, by year, or by 
geographic segment;
    <bullet> Professional staff ratios;
    <bullet> Staff turnover ratios;
    <bullet> Average training hours per professional; and
    <bullet> Partner workload.
    Firms may also communicate such data via web pages or other media, 
such as promotional publications, social media, interviews, or 
presentations via webcast or video.\114\
---------------------------------------------------------------------------

    \114\ See PCAOB Rel. No. 2024-005, at 186-187.
---------------------------------------------------------------------------

    In the supplemental request for comment, the Board proposed to 
narrow the requirements of QC 1000.53e regarding the need for an 
explanation of written metrics to those metrics that the firm makes 
publicly available. This was consistent with the initial focus of the 
requirement on public communications.\115\ The Board believes that 
recipients of nonpublic communications regarding metrics, such as 
regulators, company management, and audit committees, are generally in 
a position to request additional information about the metrics if they 
desire it. Further, some nonpublic metrics may already be calculated in 
accordance with a method prescribed by the recipient (for example, in 
response to a regulatory requirement or an audit committee request for 
proposal). In contrast, where metrics are publicly available, such as 
in firm transparency reports or promotional publications, these are 
usually one-way communications in which the external parties do not 
have the ability to ask questions or request clarification from the 
firm.
---------------------------------------------------------------------------

    \115\ See id.
---------------------------------------------------------------------------

    Several commenters supported the proposed amendments to paragraph 
.53e.\116\ One commenter said they did not object to confining the 
explanation requirement to metrics the firm makes publicly 
available.\117\ One of these commenters stated that the proposed 
amendments were generally clear and seem appropriate but suggested that 
the term ``metric'' be defined or explained in the rule text.\118\ 
Another commenter stated that the PCAOB must clearly communicate to 
firms that the intent of the provision is that firms ensure that

[[Page 59362]]

the explanation remains accurate and publicly available.\119\ Another 
commenter encouraged the Board to make explicit that simplification of 
communication requirements does not alter the firm's monitoring 
obligations.\120\ One commenter stated that it would be helpful to 
further clarify whether the requirement applies only to those 
communications required under applicable professional and legal 
requirements or to all such metrics publicly disclosed.\121\ The 
commenter further requested clarification of whether all changes to the 
calculation of disclosed metrics to which this requirement applies must 
be explained or whether this requirement applies only to material 
changes in the calculation of the disclosed metrics.\122\

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

    One commenter stated that the operability of the requirement could 
be further enhanced by restructuring the requirement into two distinct 
quality objectives--one that addresses whether the information is 
accurate and not misleading, and a second, conditional objective 
requiring an explanation for publicly communicated metrics.\123\
---------------------------------------------------------------------------

    \123\ See comment letter from KPMG.
---------------------------------------------------------------------------

    The Board is adopting the proposed amendments to QC 1000.53e with 
modifications. Specifically, the Board is revising paragraph .53e by 
adding subparagraphs .e(1) and .e(2) to more clearly distinguish firm 
responsibilities when communicating firm-level or engagement-level 
information to external parties and in written public communications. 
The Board agrees with the commenter that this change will improve the 
operability of paragraph .53e without changing a firm's 
responsibilities. In addition, the Board believes that the change will 
help to address a commenter's concern regarding the clarity of the 
provision's intent with respect to metrics communicated in writing and 
made publicly available by the firm.
    The requirement in paragraph .53e(2) applies to any metrics that 
are communicated in writing and made publicly available by the firm--it 
is not limited in application to metrics that are required to be 
communicated under applicable professional and legal requirements. 
Paragraph .53e(2) also requires a firm to communicate how the method of 
determining any metrics changed since previously communicated, if 
applicable, and that requirement applies to any such change in 
methodology, without regard to the firm's assessment of its 
materiality. The Board does not believe that it is necessary to define 
the term ``metric'' for purposes of applying paragraph .53e(2). The 
Board believes the term is reasonably understood in practice, and the 
Board previously clarified, in the supplemental request for comment, 
that the Board intends for the requirement to apply only to calculated 
measures, not to underlying data.\124\ As illustrated in the 
supplemental request for comment, if a firm publicly discloses its 
auditor-employee headcount for a region or office, the firm will not 
need to describe how it counted the employees.\125\ The requirement 
will apply, however, to any calculated figures derived using that data, 
such as the average years of experience for audit personnel (i.e., 
total years of audit experience divided by auditor-employee headcount).
---------------------------------------------------------------------------

    \125\ See id.
---------------------------------------------------------------------------

    The Board also does not believe it is necessary to clarify that the 
proposed amendment would not alter a firm's monitoring obligations. As 
stated by the commenter who suggested doing so, the amendments simplify 
communication requirements but do not affect QC 1000 monitoring 
obligations.
    The Board believes that the amendments will carry out its initial 
intent for public communications and avoid unnecessary costs associated 
with making additional disclosures to recipients who can request more 
information if they need it, while still ensuring that recipients of 
written public communications have access to an explanation of any 
metric provided.
    In addition, the Board proposed adding a note to paragraph .53e 
stating that the explanation of the method for determining metrics can 
be provided either within the public written communication that 
includes the metrics or by referring in the communication to a publicly 
available explanation presented elsewhere, such as the firm's website.
    Several commenters supported allowing firms to provide explanations 
of metrics in a publicly available location, such as the firm's 
website.\126\ One commenter stated that they supported the proposed 
amendment provided that those explanations are clear, balanced, 
accessible, and sufficiently specific to help users of the 
metrics.\127\ Another commenter stated that they favored public 
disclosures in one place for ease of use and that placement on the 
relevant website seems appropriate as long as there are clear 
instructions on how to access the explanation.\128\ The commenter 
further stated that, while disclosures on websites are useful, 
investors would want to make sure that any restatements, changes in 
definitions, or metrics are clearly noted, communicated in writing, and 
updated on a timely basis.\129\ While one commenter agreed that 
publishing an explanation of metrics on a website would not adversely 
affect the utility of metrics made public, this commenter questioned 
whether public information about firm metrics should be subject to 
certification or verification before publication.\130\ Another 
commenter said that an explanation that was accurate on the day it was 
published is of little use to an investor comparing metrics two or 
three years later, and that simplification of the requirement should 
not come at the expense of transparency or comparability over time 
within a single firm.\131\ This commenter requested that the Board 
require that any report containing a publicly disclosed metric include, 
in the report itself, a hyperlink to the explanation of how that metric 
is calculated, maintained on the firm's own website, and stated that 
the hyperlink must remain stable, archived, and year specific.\132\ 
This commenter also said that when a metric or its methodology changes 
from one year to the next, the change must be prominently identified in 
the base report itself--not only in the linked explanation--together 
with a description of the change and a presentation of the comparable 
prior year metric.\133\

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

    After consideration of the comments received,\134\ the Board is 
adopting the note to paragraph .53e as proposed but relocating it under 
new paragraph .53e(2).
---------------------------------------------------------------------------

    \134\ One commenter stated that the PCAOB should use existing 
artificial intelligence technology to aggregate metrics and related 
information from firms' websites or other public sources and make 
that information available in a centralized location on the PCAOB's 
website. See comment letter from MIAG. This suggestion is beyond the 
scope of this rulemaking.
---------------------------------------------------------------------------

    The Board believes that allowing firms to explain metrics either in 
the same communication as the metric itself or by reference to another 
publicly available explanation would streamline firms' communications 
about their audit practices without adversely affecting the quality of 
information received by

[[Page 59363]]

external parties. The Board does not believe that permitting firms this 
flexibility will create confusion for stakeholders. Given the volume of 
information that a firm might communicate about itself, and the 
possibility that the same information may be repeated through various 
communication platforms, the Board believes that permitting a firm to 
make reference to a single publicly available explanation could reduce 
unnecessary duplication of disclosures and provide additional clarity 
to stakeholders. Also for this reason, the Board believes it is not 
necessary to require a change made to a metric or its methodology be 
identified in the written communication. The Board is not requiring 
firms to provide hyperlinks for the metrics because the Board seeks to 
preserve the principles-based nature of the requirement and avoid 
prescribing a specific method that may become less effective as 
technology changes over time.
    To satisfy paragraph .53e(2), any publicly available explanation, 
including one provided through a website, would need to be clear, 
accessible, and sufficiently specific to explain how the metric was 
determined and any changes in the method used to determine the metric 
since it was last communicated. In addition, the Board does not believe 
that requiring certification or verification of such explanations is 
necessary to achieve the objectives of paragraph .53e(2). Firms would 
need to ensure that their explanations remained specific as to the 
public metric to which they relate and are publicly available for as 
long as they continue to make available the written public 
communication that refers to the location of the metrics. Firms may 
update the publicly available explanation as necessary to maintain its 
accuracy; however, such updates do not require the issuance of a new 
written public communication identifying or describing those updates.

Monitoring and Remediation Process

1. Responding to Engagement Deficiencies
    Engagement monitoring activities are designed to provide 
information on whether engagement or QC system-level areas may require 
additional attention. These activities may identify pervasive issues 
where a number of engagements have similar problems, possibly 
highlighting the need to revise methodologies, provide additional 
training, or take other actions at the QC-system level. QC 1000 
requires monitoring activities to include determining, on a timely 
basis, whether engagement deficiencies exist and, if so, taking certain 
actions in response to the identified engagement deficiencies.
    QC 1000 defines an engagement deficiency as an instance of 
noncompliance with applicable professional and legal requirements by 
the firm, firm personnel, or other participants with respect to an 
engagement of the firm, or by the firm or firm personnel with respect 
to an engagement of another firm. Under QC 1000.68, a firm is required 
to take certain action when an engagement deficiency exists, with the 
required action depending on circumstances such as whether the 
engagement is completed or still in-process or is related to work 
performed on other firms' engagements.
i. Engagement Deficiency Related to an In-Process Engagement (QC 
1000.68a)
    As originally adopted, QC 1000 requires firms, for engagement 
deficiencies relating to in-process engagements, to take action to 
address the deficiency in accordance with applicable professional and 
legal requirements (to the extent necessary, before the issuance of the 
engagement report(s)), such that the engagement report(s) are 
appropriate in the circumstances.
    The Board proposed to amend paragraph .68a to (i) replace the 
language ``the engagement report(s) are appropriate in the 
circumstances'' with ``the engagement is free of significant engagement 
deficiencies'' and (ii) add a footnote describing what significant 
engagement deficiencies are. The concept of a significant engagement 
deficiency is derived from AS 1220, and the description used in the 
proposed footnote in paragraph .68a aligns with that in AS 1220. The 
footnote to QC 1000.68a also clarifies that the concept applies to all 
engagements as that term is defined in QC 1000 (which includes, for 
example, engagements performed pursuant to PCAOB interim attestation 
standards), not only those engagements described in AS 1220.
    Many commenters supported the proposed amendments to paragraph 
.68a.\135\ However, one commenter stated that the proposed threshold 
for a ``significant engagement deficiency'' remained overly broad and 
could be interpreted to encompass any instance in which an engagement 
team failed to perform a procedure required by PCAOB standards, 
regardless of whether the omission affected the sufficiency or 
appropriateness of audit evidence supporting a material assertion or 
the engagement conclusions.\136\ This commenter suggested that the 
definition should incorporate the concepts of materiality, relevant 
assertions, and the significance of the deficiency to the overall 
audit.\137\
---------------------------------------------------------------------------

    \135\ See comment letters from Baker Tilly, CAQ, Deloitte, GT, 
KPMG, Plante & Moran, and Spitters.
    \136\ See comment letter from PICPA.
    \137\ See id.
---------------------------------------------------------------------------

    The proposed description for when a significant engagement 
deficiency exists is consistent with concepts in AS 1220. Under AS 
1220, an engagement quality reviewer (``EQR'') may provide concurring 
approval of issuance only if, after performing with due professional 
care the review required by the standard, the EQR is not aware of a 
significant engagement deficiency.\138\ The description of significant 
engagement deficiency in the proposed amendments to paragraph .68a 
appropriately focuses firms on matters that must be corrected before an 
audit report is issued or before an engagement conclusion is 
communicated to the company.\139\ Therefore, the Board does not agree 
that the description is overly broad; a significant engagement 
deficiency would not be any instance in which an engagement team failed 
to perform a procedure required by PCAOB standards but rather is 
specifically related to the circumstances described in footnote 40A. 
Further, the Board believes the concept is well understood by the 
profession and does not require any revision.

    \139\ See Proposed Auditing Standard--Engagement Quality Review 
and Conforming Amendment to the Board's Interim Quality Control 
Standards, PCAOB Rel. No. 2008-002 (Feb. 26, 2008), at 16 
(describing significant engagement deficiencies).
---------------------------------------------------------------------------

    The Board is adopting the amendments to paragraph .68a as proposed.
ii. Evaluating Whether Similar Engagement Deficiencies Exist on Other 
Engagements (QC 1000.68d)
    As originally adopted, QC 1000 requires that, when the firm 
determines that an engagement deficiency exists, the firm should 
evaluate whether similar engagement deficiencies exist in other in-
process engagements, completed engagements (unless it is probable that 
the engagement report is not being relied upon), and work performed on 
other firms' engagements, and if so, take actions as required by 
paragraphs .68a-c, as applicable.
    The Board proposed to limit the requirement to evaluate whether 
similar engagement deficiencies exist so it would apply only with 
respect to a

[[Page 59364]]

subset of engagement deficiencies, specifically those that resulted or 
could result (i) a failure to obtain sufficient appropriate evidence to 
support the conclusion reached on an engagement \140\ or (ii) an 
inappropriate overall conclusion on the subject matter of an 
engagement.
---------------------------------------------------------------------------

    \140\ Because QC 1000 covers not only audit engagements but also 
review engagements and attestation engagements, reference to 
``sufficient appropriate evidence'' is necessary as this concept 
aligns with the audit, review, and attestation standards.
---------------------------------------------------------------------------

    Most commenters generally supported the proposed amendments to 
paragraph .68d.\141\ The Board is adopting the amendments to paragraph 
.68d as proposed, along with a new note discussed further below.
---------------------------------------------------------------------------

    \141\ See comment letters from Baker Tilly, BDO, CAQ, CBIZ, 
Deloitte, EY, GT, ICGN, KPMG, PICPA, Plante & Moran, RSM, SCCG, and 
Spitters.
---------------------------------------------------------------------------

    The discussion below addresses specific commenter feedback related 
to the proposed amendments.
a. ``Resulted or Could Result in''
    Several commenters raised concern regarding the proposed language 
``resulted or could result in.'' \142\ Commenters stated that the 
language would introduce new complexity \143\ and interpretation 
challenges,\144\ or would involve substantial implementation effort 
with limited incremental investor protection.\145\ One commenter stated 
that without further context, the term ``could'' effectively sets a 
threshold closer to a remote possibility, which, in practice, would 
require firms to evaluate an unbounded population of engagements.\146\ 
This commenter suggested that the Board consider revising the language 
to specify that the requirement applies ``where there is a reasonable 
possibility'' that an engagement deficiency could result in either a 
failure to obtain sufficient appropriate audit evidence or an 
inappropriate overall conclusion, to distinguish from those that 
represent more remote possibilities.\147\ Another commenter recommended 
changing the proposed language to ``reasonably could result.'' \148\ 
Another commenter stated that it was not clear whether ``could'' should 
be assessed at the individual engagement level or at a broader thematic 
level, such as when a theme or trend of similar engagement deficiencies 
emerges.\149\ Another commenter stated that a deficiency that appears 
immaterial on the engagement where it was first identified can still be 
a symptom of a firm-wide QC weakness and a narrower trigger reduces the 
number of opportunities a firm has to find that pattern before it 
results in an audit failure.\150\ One commenter highlighted that the 
intended benefits of the proposed amendment could be offset by concerns 
regarding specific provisions (i.e., the ``could result in'' 
language).\151\ Another commenter stated that it was difficult to 
determine whether the proposed amendment will meaningfully reduce 
complexity, subjectivity, or implementation costs.\152\ The Board is 
concerned that some commenters may have misinterpreted the intent of 
the phrase ``could result in.'' As adopted, QC 1000 requires the firm 
to evaluate all engagement deficiencies under paragraph .68d. The goal 
of the amendment is to narrow the types of engagement deficiencies 
subject to the evaluation to only those that relate to obtaining 
sufficient appropriate evidence or the overall conclusion of an 
engagement.\153\ Other engagement deficiencies would not need to be 
evaluated under paragraph .68d, as amended. Such other engagement 
deficiencies include, for example, engagement deficiencies related to 
communications to the audit committee; the filing of Form AP, Auditor 
Reporting of Certain Audit Participants; or the registration status of 
an other auditor that performed substantial role work.\154\ In other 
words, this ``could result in'' language is not intended to introduce 
an assessment of the likelihood that the engagement deficiency could 
result in, for example, a failure to obtain sufficient appropriate 
evidence to support the conclusion on another engagement. This language 
is instead intended to help firms assess whether a particular 
engagement deficiency falls within either of the two types of 
engagement deficiencies subject to the evaluation under the revised 
paragraph .68d.

    \151\ See comment letter from KPMG.
    \152\ See comment letter from GT.
    \153\ With respect to examples of the type of engagement 
deficiencies that relate to reaching an inappropriate overall 
conclusion on the subject matter of an engagement, see PCAOB Rel. 
No. 2008-002, at 16 n.29, which states that ``[i]nappropriate 
conclusions on the subject matter of the engagement would include, 
for example, a failure to appropriately modify the engagement 
conclusion in response to: (1) a material departure from generally 
accepted accounting principles or (2) a material weakness in 
internal control over financial reporting.''
    \154\ These types of engagement deficiencies would still be 
required to be addressed in accordance with paragraphs .68a-c and to 
be evaluated to determine whether QC deficiencies exist in 
accordance with paragraph .72.
---------------------------------------------------------------------------

    For example, if the engagement deficiency related to not making a 
required communication to the audit committee, this type of engagement 
deficiency does not affect the auditor's ability to obtain sufficient 
appropriate audit evidence or reach the appropriate overall conclusion 
of the engagement and, therefore, would not be within the scope of the 
revised paragraph .68d. In contrast, if the engagement deficiency 
related to the auditor not making or observing a physical inventory 
count in accordance with AS 2510, Auditing Inventories, this type of an 
engagement deficiency would be within the scope of paragraph .68d, 
because it relates to obtaining sufficient appropriate evidence.
    Some commenters requested clarification of an example the Board 
provided in the supplemental request for comment.\155\ To clarify and 
illustrate the application of the ``resulted or could result in'' 
language in paragraph .68d, consider the following scenario: During 
internal monitoring activities for the current year, a firm selected 
one of its completed engagements for inspection and identified that the 
engagement team failed to evaluate cash confirmation exceptions 
pursuant to AS 2310.20. As a result, the engagement team violated PCAOB 
requirements (i.e., applicable professional and legal requirements) and 
the firm determined that an engagement deficiency exists. Because 
noncompliance with the requirement of AS 2310.20 (that is, the failure 
to evaluate confirmation exceptions) relates to obtaining sufficient 
appropriate evidence (i.e., it could result in a failure to obtain such 
evidence), this engagement deficiency meets the requirement for 
evaluation under the revised language of paragraph .68d.\156\
---------------------------------------------------------------------------

    \155\ See comment letters from Baker Tilly, BDO, CAQ, Deloitte, 
EY, GT, PICPA, and RSM.
    \156\ The Board has provided a continuation of this example 
below.
---------------------------------------------------------------------------

    The Board believes that the amendment appropriately focuses a 
firm's attention and efforts on the types of engagement deficiencies 
that represent the greatest risk to audit quality. It also reduces 
compliance costs by narrowing the population of engagement deficiencies 
that a firm is required to evaluate.
b. ``Evaluate Whether Similar Engagement Deficiencies Exist''
    A commenter stated that the nature and extent of the procedures 
required to evaluate whether similar engagement

[[Page 59365]]

deficiencies exist should be more explicitly grounded in the root cause 
of the engagement deficiency identified and an assessment of whether 
that root cause suggests a potential QC deficiency.\157\ This commenter 
suggested that an evaluation anchored to root cause would provide a 
more meaningful and risk-based framework for determining the scope of 
further procedures.\158\ As it relates to the evaluation required under 
paragraph .68d, another commenter requested scenarios to help firms 
distinguish between engagement deficiencies and identified root causes 
that are (i) indicative of systemic issues and (ii) isolated 
incidents.\159\
---------------------------------------------------------------------------

    \157\ See comment letter from Deloitte.
    \158\ See id.
    \159\ See comment letter from GT.
---------------------------------------------------------------------------

    As described in the QC 1000 2024 adopting release, understanding 
the nature of the engagement deficiency will assist the firm in 
determining the extent of the necessary evaluation.\160\ The intent of 
the requirement to evaluate whether similar engagement deficiencies 
exist was not to require an unbounded look at every engagement the firm 
has. The Board believes understanding the circumstances that led to the 
engagement deficiency (e.g., the underlying cause) would help the firm 
identify other engagements to evaluate for similar engagement 
deficiencies. The Board acknowledges, as commenters suggested, that 
this was not clear in the proposed amendments. Therefore, the Board is 
adding a new note to paragraph .68d to indicate that understanding the 
circumstances that led to the engagement deficiency may assist the firm 
in identifying other engagements (or work performed by the firm on 
other firms' engagements) to evaluate for similar engagement 
deficiencies.
---------------------------------------------------------------------------

    \160\ See PCAOB Rel. No. 2024-005, at 225.
---------------------------------------------------------------------------

    The procedures performed can be scalable and practical in the 
circumstances and may be developed based on the nature of the 
engagement deficiency. However, it would not be appropriate for a 
firm's evaluation to be based on narrower criteria than those 
underlying the cause(s) for the engagement deficiency, nor would it be 
appropriate to include only a subset of the engagements that are 
identified based on the understanding of the circumstances that led to 
the engagement deficiency.
    To continue with the example provided above regarding cash 
confirmations, the firm then gained an understanding of the 
circumstances that led to the engagement deficiency (e.g., the 
underlying cause) to identify which other engagements to evaluate for 
similar engagement deficiencies. In this example, the firm might 
determine that the engagement deficiency was caused by an error in the 
firm's cash confirmations methodology, which is required to be used on 
all engagements that use cash confirmations. To identify whether other 
engagements used the same methodology (or, in the case of in-process 
engagements, are currently using the same methodology), the firm sends 
an inquiry email to each engagement partner. Based on the responses 
received to the emails and any follow-up with non-respondents, the firm 
identifies the engagements (and work performed on other firms' 
engagements) that followed the same methodology. It is these 
engagements and work performed on another firm's engagements that 
followed the same methodology that the firm will evaluate for similar 
engagement deficiencies.
    If the firm identifies, for example, twenty engagements that 
followed the same cash confirmations methodology, the firm evaluates 
whether a similar engagement deficiency exists on each of the twenty 
engagements, i.e., a failure to evaluate confirmation exceptions 
pursuant to AS 2310.20. Out of the twenty engagements, if the firm 
identifies four engagements in which the engagement team did not 
perform procedures to evaluate confirmation exceptions pursuant to AS 
2310.20, then the firm would need to take appropriate actions pursuant 
to subparagraphs a-c of paragraph .68 on each of those four 
engagements.
    Importantly, paragraph .68d does not prescribe the manner in which 
the firm would identify engagements to evaluate. In the above example, 
the firm decided to send an email to each engagement partner to 
identify engagements that followed the same methodology. However, the 
firm could use other approaches, such as a data analysis tool or 
performing a search of engagement files, to identify engagements that 
followed the same methodology. The evaluation approach a firm takes may 
differ depending on the nature of the engagement deficiency, the 
circumstances that led to the engagement deficiency, and a firm's 
specific facts and circumstances. As discussed above, once the firm 
identifies the population of engagements subject to the evaluation of 
whether similar engagement deficiencies exist, it would not be 
appropriate for a firm's evaluation to be based on narrower criteria 
nor would it be appropriate to evaluate only a subset of the 
engagements that were identified.
    The following graphic illustrates the process for evaluating 
whether similar engagement deficiencies exist:

c. Response to Other Commenter Feedback
    One commenter did not support a requirement that would require the 
firm, after finding an engagement deficiency in one engagement, to 
evaluate whether similar deficiencies exist in all other completed 
engagements.\161\ This commenter stated that the cost of the 
requirement could be extremely high and it is unclear whether the 
benefit would outweigh the cost.\162\ This commenter suggested that the 
Board instead change the requirement so that examining a completed 
engagement would be required only when, based on the information 
available at the time, the firm believed that it was probable the 
financial statements were materially misstated and the likelihood was 
more than remote that the audit report was still being relied 
upon.\163\ The Board does not agree with the commenter who stated that 
the amendment would require that the firm evaluate whether similar 
deficiencies exist in all other completed engagements, as the note to 
paragraph .68d indicates understanding the circumstances that led to 
the engagement deficiency may assist the firm in identifying other 
engagements to evaluate for similar engagement deficiencies.

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

    A commenter stated that a deficiency found in one engagement should 
prompt the firm to ask whether the same problem exists in other 
engagements and why it occurred, with the answers feeding back into the 
firm's risk assessment.\164\ The Board agrees that an engagement 
deficiency identified in one engagement may provide information that is 
relevant to the firm's broader monitoring and remediation and risk 
assessment processes. All engagement deficiencies are subject to action 
as required under paragraph .68a-c (in that particular engagement), and 
certain engagement deficiencies will require evaluation under paragraph 
.68d. Furthermore, all engagement deficiencies are treated as QC 
observations under paragraph .72 and must be evaluated to determine 
whether they are QC deficiencies. Additionally, under paragraph 
.20a(3), the firm obtains an understanding of information from the 
firm's monitoring and remediation activities, including its 
identification of engagement deficiencies, in identifying and assessing 
quality risks. In this way, the evaluation of engagement deficiencies 
represents one part of the broader monitoring and remediation feedback 
loop: information identified through that process informs the firm's 
evaluation of QC observations and feeds back into the firm's 
identification and assessment of quality risks.
---------------------------------------------------------------------------

    \164\ See comment letter from CFA.
---------------------------------------------------------------------------

    This commenter also stated that deficiency rates are not materially 
better than in the early years of the inspection program more than 
twenty years ago and suggested this is not the moment to narrow the 
lens through which firms look for systemic problems.\165\ The Board 
believes that the amendments to paragraph .68d appropriately focus 
firms' evaluations on engagement deficiencies related to obtaining 
sufficient appropriate evidence to

[[Page 59367]]

support the conclusion reached on an engagement or the overall 
conclusion on the subject matter of an engagement that may indicate 
systemic issues on the firm's engagements.
---------------------------------------------------------------------------

    \165\ See id.
---------------------------------------------------------------------------

    A commenter suggested that the Board could further enhance the 
proposed amendment by aligning more closely with ISQM 1, which permits 
firms to use their judgment to determine the nature and extent of any 
investigation of identified engagement deficiencies and whether those 
deficiencies might indicate a deficiency in the system of quality 
management.\166\ The Board believes the requirement in paragraph .68d 
is fundamental to achieving the objective of the QC system that each 
engagement report issued by the firm is in accordance with applicable 
professional and legal requirements.\167\
---------------------------------------------------------------------------

    \166\ See comment letter from PICPA.
    \167\ See QC 1000.05.
---------------------------------------------------------------------------

    A commenter questioned why only items (1) and (2) from footnote 40A 
to proposed paragraph .68a were included in proposed paragraph .68d, 
while items (3) and (4) (the engagement report is not appropriate in 
the circumstances and the [filig]rm is not independent of its client, 
respectively) were not.\168\ With regard to paragraph .68d, the 
amendment focuses on those types of engagement deficiencies that most 
directly affect the sufficiency and appropriateness of procedures 
performed on the engagement as well as the ultimate opinion expressed 
by the firm.
---------------------------------------------------------------------------

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

2. Definition of QC Deficiency
    As originally adopted, the note to paragraph .A8(1) of the 
definition of QC deficiency states that the likelihood of not achieving 
the reasonable assurance objective or one or more quality objectives 
would be above an acceptably low level if, for example, a quality 
objective is not established, a quality risk is not properly identified 
or assessed, or a quality response is not properly designed or 
implemented or is not operating effectively.
    The Board proposed to amend this note to clarify that a failure of 
a quality response would be regarded as evidencing a QC deficiency only 
if other quality responses do not achieve the relevant objective(s). As 
stated in the QC 1000 2024 adopting release, the relationship across 
quality objectives, quality risks, and quality responses is generally 
not one-to-one.\169\ Most quality objectives are likely to have 
multiple quality risks. Some quality risks may affect one or more 
quality objectives, either within a single component or across several 
components, and may require multiple quality responses. Some quality 
responses may address multiple quality risks.
---------------------------------------------------------------------------

    \169\ See PCAOB Rel. No. 2024-005, at 42.
---------------------------------------------------------------------------

    Many commenters supported the proposed amendment to the definition 
of QC deficiency,\170\ noting, for example, that allowing firms to take 
compensating quality responses into account when determining whether a 
QC deficiency exists better reflects how a risk-based system of quality 
control operates in practice and also aligns more closely with the 
principles-based framework of other quality management standards, such 
as ISQM 1.
---------------------------------------------------------------------------

    \170\ See comment letters from AAA, Baker Tilly, BDO, CAQ, 
Crowe, Deloitte, EY, GT, KPMG, Kramer, PICPA, Plante & Moran, PwC, 
RSM, and SCCG.
---------------------------------------------------------------------------

    Two commenters suggested revisions to the proposed amendment.\171\ 
One commenter stated that the rule text could clarify that multiple 
other quality responses are not necessarily required by adding the 
words ``one or more'' before ``other quality responses'' in the Note to 
paragraph .A8(1) for situations where there is just one other quality 
response.\172\ The Board believes the rule text is sufficiently clear 
that the clause ``and other quality responses do not achieve the 
relevant objective(s)'' applies only if the firm has designed and 
implemented at least one other quality response relative to the 
objective(s). Another commenter suggested amending the definition as 
follows: ``(other quality responses have been implemented to address 
the same risk, and) `other quality responses do not achieve the 
relevant objectives.' '' \173\ The Board does not believe it is 
necessary for the rule text to specify that ``other quality responses'' 
must have been designed and implemented to address the particular 
quality risk. As stated in the supplemental request for comment and 
reiterated here, when firms have implemented more than one quality 
response to address the same quality risk, they can take those other 
quality responses into account when determining whether a QC deficiency 
exists.
---------------------------------------------------------------------------

    \171\ See comment letters from Kramer and Spitters.
    \172\ See comment letter from Kramer.
    \173\ See comment letter from Spitters.
---------------------------------------------------------------------------

    One commenter expressed concern that without a documented, 
inspectable basis for concluding that a ``compensating response'' 
actually operated effectively, this amendment risks becoming a way to 
explain away deficiencies rather than a genuine test of whether 
investors remain protected.\174\ Another commenter expressed concern 
that the proposed amendment would give firms/networks additional 
temptation to identify compensating responses when the linkage is 
tenuous.\175\ The Board believes the revised note makes clear that, 
when a quality response is not properly designed or implemented or is 
not operating effectively, the other quality responses would need to 
achieve the relevant objective(s), that is, they would need to be 
properly designed, implemented, tested, and found to operate 
effectively. And, as one commenter observed, paragraph .82 requires 
firms to document their evaluation of QC observations to determine 
whether QC deficiencies exist and the basis for each 
determination.\176\
---------------------------------------------------------------------------

    \174\ See comment letter from CFA.
    \175\ See comment letter from Grosvenor.
    \176\ See comment letter from CFA.
---------------------------------------------------------------------------

    Another commenter stated that it is unclear how allowing the 
evaluation of compensating controls will work in practice.\177\ For 
example, where a quality risk has a single response that fails, the 
commenter stated it was unclear whether firms may consider other 
responses that mitigate other identified risks to support achievement 
of the overall objective.\178\ This commenter suggested that there may 
be responses where a precision level is too high to singularly address 
a specific risk on their own, but when considered collectively, may 
reduce the risk of failing to achieve the objective to an acceptable 
level.\179\
---------------------------------------------------------------------------

    \177\ See comment letter from RSM.
    \178\ See id.
    \179\ See id.
---------------------------------------------------------------------------

    As explained in the QC 1000 2024 adopting release, the purpose of 
this note is to provide examples of circumstances where the likelihood 
of the firm not achieving the reasonable assurance objective or one or 
more quality objectives would not be reduced to an acceptably low 
level.\180\ The amendments to this note further emphasize that, when a 
quality response is not properly designed or implemented or is not 
operating effectively and other quality responses do not achieve the 
relevant objective(s), the likelihood of the firm not achieving the 
reasonable assurance objective or one or more quality objectives has 
not been reduced to an acceptably low level. Under QC 1000, quality 
risks are defined as ``[r]isks (whether or not related to intentional 
acts by firm personnel or other participants to deceive or to violate 
applicable professional and legal requirements) that, individually or 
in combination

[[Page 59368]]

with other risks, have a reasonable possibility of occurring and, if 
they were to occur, a reasonable possibility of adversely affecting the 
firm's achievement of one or more quality objectives.'' The amendment 
clarifies that, when firms have implemented more than one quality 
response to address the same quality risk, they can take those other 
quality responses into account when determining whether a QC deficiency 
exists; if the other quality responses were effective in achieving the 
relevant objective(s), no QC deficiency would exist.
---------------------------------------------------------------------------

    \180\ See PCAOB Rel. No. 2024-005, at 231.
---------------------------------------------------------------------------

    After consideration of the comments received, the Board is adopting 
the amendment to the definition of QC deficiency as proposed.

Evaluation of and Reporting on the QC System

1. Annual Evaluation of the QC System
i. Evaluation Date
    As originally adopted, QC 1000 requires that the firm perform an 
evaluation of the effectiveness of its QC system annually as of 
September 30.
    The Board proposed to amend QC 1000 to permit firms to select their 
own annual evaluation date for their QC system by adding a new defined 
term, ``evaluation date,'' defined as the date selected by the firm as 
of which to evaluate its QC system under paragraph .77, and making 
conforming changes to paragraph .77.
    The Board also proposed to include language in a new footnote to 
guide the firm's selection of its evaluation date by recognizing that 
the firm's choice may be influenced by the nature and circumstances of 
the firm and its engagements, including, for example, the firm's fiscal 
year-end or the timing of monitoring activities.
    All commenters who commented on this aspect of the proposed 
amendments expressed support.\181\ One commenter, who did not object to 
this aspect of the proposed amendments, expressed concern that timing 
should not become a tool for managing findings and a firm should not be 
able to use its initial selection, or a later change of date, to defer 
capturing known or anticipated inspection findings within an evaluation 
period.\182\ This commenter, however, acknowledged that under the 
amendments, no period of time escapes evaluation altogether and any 
change of evaluation date must be reported to the Board together with 
the firm's rationale for the change.\183\ The Board agrees with the 
commenter that these are useful guardrails.\184\
---------------------------------------------------------------------------

    \181\ See comment letters from AAA, Baker Tilly, BDO, CAQ, CBIZ, 
Crowe, Deloitte, EY, Forvis, GT, ICGN, KPMG, MIAG, PICPA, Plante & 
Moran, PwC, RSM, and Spitters.
    \182\ See comment letter from CFA.
    \183\ See id.
    \184\ See id.
---------------------------------------------------------------------------

    The choice of evaluation date is an aspect of QC system design and, 
as such, has to be made and documented by the time the firm becomes 
subject to the QC 1000.06 requirement to design, implement, and operate 
an effective QC system. The firm has to have the information needed to 
identify unremediated QC deficiencies and to reach a conclusion about 
the effectiveness of its QC system as of the evaluation date, and for 
the individuals with ultimate responsibility and accountability and 
operational responsibility and accountability for the QC system as a 
whole, acting with due professional care, to certify the firm's report 
to the PCAOB on its annual evaluation of the QC system. This suggests 
that the evaluation date and the firm's monitoring and remediation 
cycle ought to be coordinated so that sufficient, timely information is 
available when needed about the implementation and operation of the QC 
system (including the status of remediation efforts) and the compliance 
of the firm's engagements with applicable professional and legal 
requirements. Because of the relationship between the evaluation date 
and the firm's monitoring and remediation activities, The Board does 
not anticipate that firms will change their selected evaluation date 
without a specific reason (e.g., regulatory requirements, business 
combination transactions, or changes in fiscal year or business 
cycles).
    The Board is adopting these amendments as proposed.
    The Board believes allowing each firm to select its evaluation date 
based on the firm's particular facts and circumstances responds to the 
implementation challenges experienced by some firms and, in particular, 
could reduce the burden and costs of multiple annual evaluations that 
some firms could have experienced due to differences in required 
evaluation dates under QC 1000 versus other regulations to which they 
are subject. This change better aligns with the flexibility provided by 
other quality management standards, which permit firms to choose their 
own evaluation date. Additionally, the Board does not believe that 
allowing firms to select their own evaluation date impairs the Board's 
ability to carry out its inspection program.
ii. Five-Month Threshold for the Initial Evaluation of the Firm's QC 
System
    The Board proposed to add language to paragraph .77 that would 
require a minimum period of operation before a firm is first required 
to evaluate its QC system. Under the proposed amendment, a firm would 
be required to evaluate its QC system once the firm has been subject to 
the requirement to design, implement, and operate a QC system under 
paragraph .06 for at least five consecutive months (whether due to the 
effectiveness of QC 1000 on December 15, 2026, or to the firm's later 
becoming subject to the requirements of QC 1000.06).
    Most commenters who commented on this topic supported the proposed 
amendment.\185\
---------------------------------------------------------------------------

    \185\ See comment letters from Baker Tilly, CAQ, ICGN, KPMG, 
PICPA, RSM, and Spitters.
---------------------------------------------------------------------------

    However, one commenter stated that the proposed approach may create 
practical challenges for firms seeking to align their QC 1000 
evaluation process with evaluations performed under other quality 
management standards, which contemplate annual evaluation periods that 
generally do not exceed twelve months.\186\ This commenter observed 
that a firm that has chosen, for example, March 31 as its evaluation 
date would likely be required to perform an evaluation under ISQM 1 or 
SQMS 1 as of March 31, 2027, while the corresponding QC 1000 evaluation 
would not occur until March 31, 2028, and would encompass a 15-month 
evaluation period.\187\ This commenter suggested that the Board could 
permit firms to perform their initial evaluation of their QC system as 
of their selected evaluation date, consistent with their normal quality 
control processes, but require the first Form QC filing only for the 
first 12-month evaluation period ending after September 30, 2027.\188\ 
This commenter believes that the Board could obtain information 
regarding that firm's initial evaluation, implementation progress, 
significant findings, and remediation activities through its oversight 
activities (e.g., inspections, implementation outreach, annual data 
requests, and other regulatory interactions) prior to the firm's first 
Form QC filing.\189\ Another commenter stated that, combined with a 
free choice of evaluation date, the proposed five-month threshold could 
defer some firms' first evaluation well into 2028.\190\ This commenter 
stated

[[Page 59369]]

that the Board should set an outer limit so that every firm completes 
its first evaluation within a reasonable period of becoming subject to 
the standard.\191\
---------------------------------------------------------------------------

    \186\ See comment letter from BDO.
    \187\ See id.
    \188\ See id.
    \189\ See id.
    \190\ See comment letter from CFA.
    \191\ See id.
---------------------------------------------------------------------------

    The Board acknowledges that, depending on the evaluation date 
chosen by the firm, the first evaluation period may encompass more than 
12 months, but observes that subsequent periods would proceed on a 12-
month cycle (absent a change of the evaluation date). The Board 
believes that this approach sets a reasonable outer limit for a firm's 
first evaluation. The Board also believes that the five-month minimum 
duration of the initial evaluation period ensures that firms have 
sufficient information to evaluate the effectiveness of their QC 
system. A firm can elect to voluntarily perform its initial evaluation 
covering a less-than-five-month period, but that evaluation would not 
be a required evaluation under QC 1000. Consequently, under General 
Instruction 4(a) to Form QC, the firm's first Form QC filing would be 
required to cover the period beginning on the date the firm first 
incurred an obligation to implement and operate a QC system under QC 
1000.06 and ending on the firm's evaluation date.
    Another commenter suggested that the five-month period should 
commence on the first day of the month immediately following the event 
that triggers the firm's obligation to design, implement, and operate 
its QC system, which would allow firms a full five-month operating 
period on which to base their evaluation.\192\ This commenter also 
requested that the Board clarify that the five-month period applies 
solely to the initial operation of the broader QC system and does not 
establish a mandatory minimum operating period for concluding that a 
specific remedial action is effective.\193\ To clarify, as noted above, 
a firm becomes subject to the requirements of QC 1000 on (1) December 
15, 2026 (the effective date of QC 1000), or (2) the day the firm 
becomes subject to the requirement to design, implement, and operate a 
QC system under paragraph .06. Therefore, in all circumstances, a 
firm's QC system will have operated for a full five months or longer 
before the firm is required to evaluate the effectiveness of its QC 
system. Additionally, because the five-month threshold refers to the 
evaluation of the effectiveness of the firm's QC system as a whole, it 
does not impose any minimum time requirement for any other purpose 
other than for QC 1000.77.
---------------------------------------------------------------------------

    \192\ See comment letter from KPMG.
    \193\ See id.
---------------------------------------------------------------------------

    Another commenter also suggested that the Board clarify whether 
engagements should be included in a firm's evaluation based on the 
financial statement year-end or the date the auditor's report is 
issued.\194\ This commenter encouraged the Board to clarify how firms 
should approach the initial evaluation when the completion of a firm's 
engagements falls outside this five-month timeframe and when the 
initial evaluation has little or no engagement activity within the 
evaluation period.\195\
---------------------------------------------------------------------------

    \194\ See comment letter from PICPA.
    \195\ See id.
---------------------------------------------------------------------------

    QC 1000 requires that the firm design, implement, and operate a 
monitoring and remediation process to provide relevant, reliable, and 
timely information about the design, implementation, and operation of 
the QC system and to provide a reasonable basis for timely detection of 
engagement deficiencies and QC deficiencies.\196\ Firms are required to 
monitor completed engagements.\197\ A completed engagement is one for 
which the firm has issued an engagement report. Firms also are 
required, depending on the size of their PCAOB audit practice, to 
either perform in-process engagement monitoring \198\ or consider doing 
so.\199\ If the firm has no completed engagements during the firm's 
initial evaluation of its QC system, in-process monitoring could 
provide relevant, reliable, and timely information about the 
performance of the firm's engagements.
---------------------------------------------------------------------------

    \196\ QC 1000.59a and b.
    \197\ QC 1000.62a.
    \198\ QC 1000.63a.
    \199\ QC 1000.63b.
---------------------------------------------------------------------------

    Finally, one commenter questioned the rationale behind the Board's 
decision to use five months as opposed to, for example, six 
months.\200\ In developing the minimum time period for the initial QC 
system evaluation, the Board determined and continues to believe that 
the five-month threshold strikes the right balance such that the QC 
system has ample time to operate while also ensuring the PCAOB's timely 
receipt of information related to firms' QC systems.
---------------------------------------------------------------------------

    \200\ See comment letter from Spitters.
---------------------------------------------------------------------------

    Accordingly, the Board is adopting this amendment as proposed.
    To illustrate how the five-month threshold for the initial 
evaluation of the firm's QC system would operate, if a firm that is 
subject to the requirements of QC 1000.06 when the standard becomes 
effective (on December 15, 2026) selects June 30 as its evaluation 
date, the firm would first evaluate the effectiveness of its QC system 
in accordance with QC 1000 as of June 30, 2027, because the firm would 
have been required to operate a QC 1000-compliant system for at least 
five months (specifically, from December 15 to June 30) as of June 30, 
2027. Alternatively, if such a firm selects March 31 as its evaluation 
date, the firm would be required to first evaluate the effectiveness of 
its QC system as of March 31, 2028, because the firm would not have 
been required to operate a QC 1000-compliant system for at least five 
months as of March 31, 2027. As another example, if a firm first became 
subject to the requirements of QC 1000.06 on June 1, 2027 (because the 
firm became subject to applicable professional and legal requirements 
with respect to an engagement at that time), and the firm selects July 
31 as its evaluation date, the firm would be required to first evaluate 
the effectiveness of its QC system as of July 31, 2028, because the 
firm would not have been required to operate a QC 1000-compliant system 
for at least five months as of July 31, 2027.
iii. Evaluation Conclusions
    As originally adopted, QC 1000 requires the firm to evaluate its QC 
system annually and conclude that the QC system is effective, is 
effective except for one or more unremediated QC deficiencies that are 
not major QC deficiencies, or is not effective (i.e., one or more major 
QC deficiencies exist).
    The Board proposed to amend the above three conclusions to align QC 
1000 more closely with other quality management frameworks. Under 
proposed paragraph .77, the firm would be required to conclude, as of 
the evaluation date, that its QC system:
    <bullet> Is effective in achieving the reasonable assurance 
objective; or
    <bullet> Is effective in achieving the reasonable assurance 
objective except for unremediated QC deficiencies that have a severe 
but not pervasive effect on the design, implementation, and operation 
of the QC system (and do not render the QC system not effective); or
    <bullet> Is not effective in achieving the reasonable assurance 
objective.
    To clarify when a firm may conclude that its QC system is effective 
in achieving the reasonable assurance objective under paragraph .77a, 
the Board proposed to include a note explaining that such a conclusion 
would be appropriate when, as of the evaluation date, there are no 
unremediated QC deficiencies other than those that, individually or in

[[Page 59370]]

combination, are not severe. This clarification was intended to 
emphasize that the presence of unremediated QC deficiencies did not, in 
all cases, preclude a conclusion under paragraph .77a that the QC 
system is effective. Rather, the determination would depend on the 
severity of those deficiencies and their effect on the firm's ability 
to achieve the reasonable assurance objective. Under the proposed 
approach, QC deficiencies that are not severe, whether considered 
individually or in combination, would not indicate that the QC system 
is failing to operate effectively, which would be consistent with the 
ISQM 1 evaluation framework and the reasonable assurance objective of 
QC 1000.
    Under proposed paragraph .77b, a firm would conclude that its QC 
system was effective in achieving the reasonable assurance objective 
except for unremediated QC deficiencies that have a severe but not 
pervasive effect on the design, implementation, and operation of the QC 
system (and do not render the QC system not effective). To clarify, 
when evaluating the effect of unremediated QC deficiencies on the QC 
system, a firm would evaluate whether the QC deficiencies have a severe 
but not pervasive effect on each of the following: (1) the design of 
the QC system, (2) the implementation of the QC system, and (3) the 
operation of the QC system. Therefore, with respect to the conclusion 
under paragraph .77b, QC deficiencies may have a severe but not 
pervasive effect on the design, implementation, or operation of the QC 
system; they need not have such an effect on all three aspects of the 
QC system for a firm to reach the conclusion under proposed paragraph 
.77b. The parenthetical statement is intended to clarify that if QC 
deficiencies are so severe as to prevent the firm from achieving the 
reasonable assurance objective, the appropriate conclusion would be 
under proposed paragraph .77c. A firm would reach the conclusion set 
forth in paragraph .77c if its QC system was not effective in achieving 
the reasonable assurance objective.
    QC 1000 specifies that an unremediated QC deficiency is one for 
which remedial actions that completely address the QC deficiency have 
not been fully implemented, tested, and found effective. The Board 
proposed to modify the existing note to paragraph .77 to explain that, 
while remedial actions must be fully implemented as of the evaluation 
date, they can be tested and found effective no later than the date 
Form QC is due under paragraph .79 (or, if earlier, the date Form QC is 
filed). The note distinguishes between the implementation of remedial 
actions and the demonstration of their effectiveness. For purposes of 
determining whether a QC deficiency is remediated, firms are expected 
to have fully implemented remedial actions as of the evaluation date, 
but the assessment of whether those actions are operating effectively 
may be supported by testing their operating effectiveness after the 
evaluation date but before the Form QC filing date.
    Commenters supported the proposed amendments to the evaluation 
framework and evaluation conclusions, particularly the effort to align 
more closely with other quality management standards.\201\ Several 
commenters noted that this alignment would reduce the complexity of 
managing evaluations under multiple frameworks and help avoid potential 
confusion among stakeholders.\202\ Two commenters observed that the 
three-tiered conclusions framework better supports informed decision-
making and meaningful communication with stakeholders, and reflects a 
more accurate representation of how QC systems operate in 
practice.\203\ Two other commenters noted that the proposed evaluation 
framework would enhance transparency by allowing firms to distinguish 
among varying degrees of effectiveness, including through the use of 
the ``except for'' conclusion.\204\ One commenter further stated that 
the proposed evaluation framework better aligns with the reasonable 
assurance objective because it clarifies that a QC system may provide 
reasonable assurance even when unremediated QC deficiencies exist.\205\ 
In addition, some commenters indicated that the proposed conclusions in 
paragraph .77 were sufficiently clear and appropriate.\206\ One 
commenter stated the evaluation framework in proposed paragraphs 
.77-.78 is generally clear but requested clarification on the latitude 
of firms to change their conclusions as of the evaluation date if, 
before the date that Form QC is filed, a firm identifies shortcomings 
when further testing its remedial actions.\207\

    While commenters generally supported the proposed framework, one 
commenter recommended expanding the ``except for'' category to include 
both ``severe but not pervasive'' and ``pervasive but not severe'' 
unremediated QC deficiencies to minimize potential blurring among the 
conclusion categories.\208\ This commenter expressed concern that a 
conclusion under paragraph .77a could be confusing because a firm may 
arrive at a favorable conclusion despite having experienced significant 
quality control issues during the evaluation period that were 
subsequently remediated.\209\ The same commenter also noted that 
deficiencies may take time to become apparent and suggested requiring 
statements or certifications indicating that firms considered 
previously unidentified deficiencies relating to prior years in their 
evaluations.\210\ Another commenter urged the Board to retain the 
``effective, with no unremediated QC deficiencies'' conclusion as 
originally adopted.\211\ The commenter expressed concern that allowing 
firms to reach an unqualified ``effective'' conclusion despite the 
existence of unremediated QC deficiencies would broaden the 
circumstances in which firms may reach a favorable conclusion.\212\

    One commenter supported the proposed modification to the existing 
note to paragraph .77 because it provides helpful guidance and better 
reflects how remediation occurs in practice.\213\ Another commenter 
questioned whether the phrase ``completely address'' in the first 
sentence of the note, which is not part of the proposed modification, 
establishes an unnecessarily stringent standard and suggested replacing 
it with ``sufficiently address.'' \214\ Another commenter requested 
clarification on the description in the release for determining whether 
a QC deficiency is remediated, specifically whether the phrase ``may be 
supported by evidence obtained from testing after the evaluation date'' 
refers to testing of instances that occurred before the evaluation date 
or the related response activities after the evaluation date.\215\ One 
commenter requested clarification on how firms should assess the effect 
of remediation efforts when frequency constraints preclude testing 
enough instances of the remedial actions in

evaluating remaining QC deficiencies.\216\

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

    In developing the proposed amendments to paragraph .77, the Board 
also considered an alternative evaluation framework under which a firm 
would be required to reach a binary conclusion (i.e., that its QC 
system is either effective or not effective in achieving the reasonable 
assurance objective).
    One commenter stated that a binary conclusion may be particularly 
appropriate for many triennial firms and suggested that a binary 
framework would simplify the evaluation process.\217\ Another commenter 
stated that whether the alternative evaluation framework with a binary 
conclusion is more appropriate is undefined, and it would be 
appropriate and constructive to retain the factors included in 
paragraph .78 (which are discussed further below) under this 
alternative framework.\218\
---------------------------------------------------------------------------

    \217\ See comment letter from Kramer.
    \218\ See comment letter from Spitters.
---------------------------------------------------------------------------

    Many commenters did not support the binary approach for the 
evaluation framework.\219\ Some commenters were concerned that it would 
limit firms' ability to communicate the nature and severity of 
identified deficiencies and would decrease alignment with other quality 
management frameworks.\220\ In addition, some commenters stated that a 
binary framework could provide insufficient information regarding 
significant deficiencies that are not pervasive enough to warrant a 
conclusion that the QC system is ineffective.\221\ Two commenters noted 
that a binary framework would be less informative.\222\ Another 
commenter expressed concern that the binary approach could reduce the 
rigor of the evaluation process.\223\ Another commenter stated that the 
existing three-tiered conclusion structure provides more meaningful 
information by distinguishing QC systems with severe but not yet 
pervasive QC deficiencies and serves as an important early-warning 
mechanism.\224\ This commenter also stated that the middle category 
allows severe but not yet pervasive unremediated QC deficiencies to be 
identified, escalated, and remediated before the QC system fails.\225\

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

    After considering the comments received, the Board is adopting the 
amendments to paragraph .77 as proposed.
    The Board believes that unremediated QC deficiencies that are 
pervasive but not severe may nevertheless allow the QC system to 
achieve its reasonable assurance objective and therefore support a 
conclusion under paragraph .77a. The Board also believes the evaluation 
framework appropriately focuses on the condition of the QC system as of 
the evaluation date and provides firms with the incentive to timely and 
effectively remediate identified QC deficiencies as of the evaluation 
date to reach a conclusion under paragraph .77a.
    The Board notes that, despite increased alignment between the 
evaluation conclusions under QC 1000 and other quality management 
standards, the possibility remains that firms may reach different 
conclusions regarding the effectiveness of their QC systems under QC 
1000 and ISQM 1 or SQMS 1. For example, there are differences in the 
professional and legal requirements that apply to a firm's audit 
practice under PCAOB standards compared to other standards, including 
variations between applicable auditing standards and independence 
requirements. The relevant populations of engagements are different. 
There could also be differences relating to the individuals who perform 
such engagements or perform activities within the QC system, including 
with regard to training and supervision. In addition, QC 1000 would 
continue to require a more structured approach to the evaluation 
process than other standards, including through the application of 
specific defined terms and factors that are required to be considered. 
The Board believes this more structured approach is important both in 
supporting consistent and appropriate evaluation of the QC system by 
firms and in providing a foundation for PCAOB oversight in the future.
    The Board does not believe that an additional certification 
requirement, as suggested by one commenter, is necessary because QC 
1000 already requires firms to consider the results of prior monitoring 
activities and remedial actions when determining the nature, timing, 
and extent of the firm's monitoring activities. The Board is also 
retaining the phrase ``completely address'' in the first sentence of 
the note to paragraph .77 describing the meaning of an unremediated QC 
deficiency. The commenter's suggested phrase ``sufficiently address'' 
could introduce subjectivity regarding whether a QC deficiency has been 
adequately remediated. The Board believes the phrase ``completely 
address'' conveys the expected level of remediation necessary before 
concluding that a QC deficiency is fully remediated.
    With respect to requests for clarifications of (i) the phrase ``may 
be supported by evidence obtained from testing after the evaluation 
date'' and (ii) frequency constraints on testing remedial actions, the 
note to paragraph .77 distinguishes between the implementation of 
remedial actions and the demonstration of their effectiveness. For 
purposes of determining whether a QC deficiency is remediated, firms 
are expected to have fully implemented remedial actions as of the 
evaluation date, but the assessment of whether those actions are 
operating effectively may be supported by testing their operating 
effectiveness after the evaluation date but before the Form QC filing 
date. For example, when a remedial action has been implemented prior to 
the evaluation date but evidence from multiple instances of operation 
is needed to conclude that the remediation is effective, the firm may 
test one or more instances of operation of the remedial action that 
took place after the evaluation date but before the filing of Form QC 
to demonstrate effectiveness of the remedial action. However, if 
multiple instances of operation are needed to conclude that a remedial 
action is effective and, due to frequency constraints, only one 
instance of operation can be tested before the filing of Form QC, then 
the QC deficiency would be considered an unremediated QC deficiency.
    Regarding the requested clarification of a firm's ability to change 
its conclusion on QC effectiveness between the evaluation date and the 
date Form QC is filed, the Board notes that the firm's final conclusion 
about the effectiveness of its QC system is the conclusion reported on 
Form QC. When additional information related to the QC system as of the 
evaluation date becomes available before Form QC is filed, the firm is 
expected to evaluate that information and make appropriate 
determinations regarding the information in a timely manner and report 
any relevant conclusions it reaches.

iv. Evaluating the Severity and Pervasiveness of Unremediated QC 
Deficiencies
    As originally adopted, QC 1000.78 includes the concept of a ``major 
QC deficiency'' and provides presumptions and factors to determine 
whether a major QC deficiency exists and, therefore, the QC system is 
not effective. The Board proposed to eliminate the concept of a ``major 
QC deficiency,'' including the associated presumptions. The Board 
proposed to retain, in modified form, the factors to consider in 
evaluating the severity and pervasiveness of unremediated QC 
deficiencies.
    Specifically, the Board proposed to amend paragraph .78 to require 
firms to evaluate the severity and pervasiveness of unremediated QC 
deficiencies in reaching the evaluation conclusion under paragraph .77. 
Proposed paragraph .78 clarifies that the firm's evaluation would 
consider all unremediated QC deficiencies individually and in 
combination, considering both quantitative and qualitative 
implications. The proposed paragraph .78 also describes severity and 
pervasiveness for purposes of this evaluation. Severity reflects the 
seriousness of a QC deficiency or combination of QC deficiencies, 
including the potential impact on the firm's ability to achieve the 
reasonable assurance objective. Pervasiveness reflects the breadth of 
impact of the QC deficiency or combination of QC deficiencies on the QC 
system or across the firm's portfolio of engagements.
    Commenters generally supported removing the concept of a ``major QC 
deficiency'' from QC 1000.\226\ Some commenters noted that the concept 
constituted a fundamental departure from other quality management 
standards and reduced consistency across quality management 
frameworks.\227\ One commenter stated that the removal of the major QC 
deficiency concept and related presumptions could reduce the 
information value of the evaluation conclusions and lessen the 
prominence with which serious QC issues are escalated and 
communicated.\228\ The commenter urged the Board to preserve escalation 
presumptions in some form and clarify how serious QC issues that fall 
short of overall ineffectiveness will be escalated and communicated if 
the ``major QC deficiency'' concept is removed.\229\

    \228\ See comment letter from CFA.
    \229\ See id.
---------------------------------------------------------------------------

    Some commenters supported the factors used to evaluate the severity 
and pervasiveness of unremediated QC deficiencies, stating that the 
factors promote consistency and rigor in the evaluation process.\230\ 
One commenter stated that the factors in proposed paragraph .78 
appropriately address QC deficiencies individually and collectively and 
account for both qualitative and quantitative considerations.\231\
---------------------------------------------------------------------------

    \230\ See comment letters from BDO, CAQ, GT, and KPMG.
    \231\ See comment letter from Spitters.
---------------------------------------------------------------------------

    One commenter stated that considering deficiencies ``in 
combination'' when assessing severity may blur the distinction between 
the concepts of severity and pervasiveness.\232\ The same commenter 
also indicated that this distinction may be further blurred because the 
same factors are used to evaluate both severity and pervasiveness.\233\ 
Another commenter supported the objective of providing a structured 
framework for evaluating the severity and pervasiveness of unremediated 
QC deficiencies but viewed proposed paragraph .78 as overly complex and 
prescriptive.\234\ The same commenter suggested an alternative model 
for paragraph .78, incorporating concepts from the AICPA Peer Review 
Program guidance for evaluating deficiencies, that would focus on the 
nature, cause, and effect of the deficiency, including: (1) whether the 
deficiency is an isolated event or a systemic weakness; (2) the 
significance of the deficiency to the firm's practice, including the 
likelihood to affect other engagements or components of the QC system; 
(3) the effect of the deficiency on the firm's ability to achieve the 
reasonable assurance objective; and (4) the extent to which remedial 
actions have been implemented and demonstrated to be effective.\235\

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

    The Board does not believe that removing the major QC deficiency 
concept removes the framework's ability to identify and appropriately 
distinguish particularly severe QC deficiencies. Under the amended 
evaluation framework, firms would still be required to evaluate the 
severity and pervasiveness of all unremediated QC deficiencies, 
individually and in combination, and report information regarding 
unremediated QC deficiencies in Form QC regardless of the evaluation 
conclusion reached. The evaluation conclusions in paragraph .77 and the 
factors in paragraph .78 would provide a structured framework for 
identifying and assessing unremediated QC deficiencies and for 
communicating unremediated QC deficiencies to the PCAOB. Further, the 
conclusion under paragraph .77b can only be selected when unremediated 
QC deficiencies have a severe but not pervasive effect on the QC system 
and also do not render the QC system not effective. As reflected in the 
parenthetical statement in paragraph .77b, if unremediated QC 
deficiencies are so severe as to prevent the firm from achieving the 
reasonable assurance objective, the firm would be required to conclude 
under paragraph .77c that its QC system is not effective in achieving 
the reasonable assurance objective.
    The Board believes it is important to consider unremediated QC 
deficiencies both individually and in combination because doing so may 
reveal patterns of similar findings or indicate a broader issue that 
may not be evident from evaluating each deficiency in isolation. The 
Board also believes that allowing the same factors to inform 
assessments of both severity and pervasiveness provides firms with 
relevant information for their evaluations. In many cases, it may not 
be practicable to categorize a factor as relating exclusively to either 
severity or pervasiveness. Additionally, the Board believes the 
alternative factors for evaluating deficiencies, suggested by one 
commenter, are already reflected in paragraph .78 as proposed. The 
factors in paragraph .78 are intended to assist firms in performing the 
internal evaluation required to reach a conclusion under paragraph .77. 
The Board believes the approach in paragraph .78 provides clear 
direction to firms in evaluating the severity and pervasiveness of 
unremediated QC deficiencies.
    One commenter noted that the term ``component'' in proposed 
paragraph .78a is undefined and could be unclear and recommended that 
the standard more explicitly link the term to the eight integrated 
components of a firm's QC system described in QC 1000.03, either 
through a cross-reference or by using consistent terminology.\236\ To 
clarify the intended meaning of the term ``component'' in proposed 
paragraph .78a, the Board is revising the paragraph to refer to the 
``components of the firm's QC system.''
---------------------------------------------------------------------------

    \236\ See comment letter from Kramer.

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

[[Page 59373]]

    Another commenter questioned if the factor of persistence in 
paragraph .78d affects the evaluation of severity and pervasiveness and 
provided an example of an issue that persists unchanged for three 
years.\237\ The Board continues to believe that the persistence of a 
deficiency may provide useful information in assessing its severity and 
pervasiveness. However, persistence alone may not determine the 
severity or pervasiveness of a QC deficiency, and those assessments 
depend on the particular facts and circumstances as well as other 
factors in paragraph .78.
---------------------------------------------------------------------------

    \237\ See comment letter from Grosvenor.
---------------------------------------------------------------------------

    Another commenter stated that the proposed amendments to paragraphs 
.78e-f introduce the phrase ``or could result in'' and expressed 
concern that the use of ``could'' may imply an evaluation threshold 
approaching absolute assurance because it encompasses even remote 
possibilities.\238\ This commenter suggested revising the language to 
refer instead to circumstances ``where there is a reasonable 
possibility.'' \239\ The factors to consider in evaluating the severity 
and pervasiveness of unremediated deficiencies do not relate to 
providing any level of assurance. They are intended to help the firm 
evaluate how severe or pervasive unremediated QC deficiencies are in 
performing the evaluation and reaching a conclusion regarding the 
effectiveness of the firm's QC system. The use of ``could'' in these 
factors is intended for the firm to evaluate whether the unremediated 
QC deficiencies remaining as of the evaluation date have the potential 
to cause significant engagement deficiencies or revisions of engagement 
reports, or to be associated with financial statement restatements or 
reissuances of management reports on internal control over financial 
reporting or broker-dealer compliance or exemption reports that are the 
subject of the firm's audit or attestation engagements.
---------------------------------------------------------------------------

    \238\ See comment letter from KPMG.
    \239\ See id.
---------------------------------------------------------------------------

    One commenter expressed concern that the wording regarding the 
significance to the firm's portfolio of engagements in paragraph .78g 
could unintentionally imply that some engagements are less important 
than others.\240\ While all unremediated QC deficiencies are required 
to be evaluated for severity and pervasiveness, the Board recognizes 
that there may be certain engagements where unremediated QC 
deficiencies are more likely to affect the firm's overall practice 
under PCAOB standards due to the engagement's significance to the 
firm's portfolio. For example, if an unremediated QC deficiency is 
likely to result in engagement deficiencies that occur across the 
primary industry that represents a substantial portion of the firm's 
PCAOB engagements, the unremediated QC deficiency could be severe or 
pervasive because of its significance to the firm's engagement 
portfolio.
---------------------------------------------------------------------------

    \240\ See comment letter from PICPA.
---------------------------------------------------------------------------

    Another commenter supported the factors if they continue to include 
consideration of whether remedial actions have been implemented, 
tested, and determined to be effective, consistent with paragraph 
.78h.\241\
---------------------------------------------------------------------------

    \241\ See comment letter from ICGN.
---------------------------------------------------------------------------

    The Board is adopting the factors in paragraph .78 as proposed with 
the revision made to paragraph .78a discussed above. The Board believes 
these factors promote consistency by identifying circumstances that are 
particularly relevant in assessing the severity and pervasiveness of 
unremediated QC deficiencies. The final factors with general 
descriptions are:
    a. The number and nature of components of the firm's QC system or 
quality objectives directly or indirectly affected.
    This factor focuses on how many components of the firm's QC system 
or quality objectives are affected, what they are, and whether the 
impact is direct or spread through other components or quality 
objectives.
    b. The extent to which the unremediated QC deficiency or 
combination of unremediated QC deficiencies relates to a component, 
quality objective, or quality response that affects the design or 
operation of other aspects of the QC system.
    This factor focuses on how widespread the impact of the 
unremediated QC deficiency or combination of unremediated QC 
deficiencies is throughout the QC system.
    c. The number and pervasiveness of root causes.
    The factor focuses on what the firm's root cause analysis reveals 
about why the QC deficiency occurred and how significantly or broadly 
it affects the QC system.
    d. The persistence of the unremediated QC deficiency or combination 
of unremediated QC deficiencies over time.
    This factor focuses on the existence of a QC deficiency or 
combination of QC deficiencies that recurs or continues unremediated 
year over year.
    e. Whether the unremediated QC deficiency or combination of 
unremediated QC deficiencies has resulted or could result in 
significant engagement deficiencies.
    This factor focuses on whether the unremediated QC deficiency or 
combination of unremediated QC deficiencies is leading to or likely to 
lead to significant engagement deficiencies.
    f. Whether the unremediated QC deficiency or combination of 
unremediated QC deficiencies has resulted or could result in the need 
for revisions to engagement reports, or is or could be associated with 
restatements of financial statements or reissuances of company-prepared 
reports that are the subject of audit or attestation engagements.\242\
---------------------------------------------------------------------------

    \242\ Company-prepared reports subject to audit or attestation 
engagements include the report on internal control over financial 
reporting and broker-dealer compliance and exemption reports.
---------------------------------------------------------------------------

    This factor focuses on whether the unremediated QC deficiency or 
combination of unremediated QC deficiencies has already led or could 
lead to revisions of engagement reports, or is or could be associated 
with financial statement restatements or reissuances of management 
reports on internal control over financial reporting or broker-dealer 
compliance or exemption reports.
    g. With respect to the factors in subparagraphs d-f, the number and 
significance (to the firm's portfolio of engagements) of engagements 
that are affected by the unremediated QC deficiency or combination of 
unremediated QC deficiencies or are likely to be affected in the future 
in the absence of remediation, and the nature of the effect.
    This factor focuses on how important the affected engagements are 
compared to the firm's overall practice under PCAOB standards. The 
number and significance of affected engagements to the firm's portfolio 
of engagements depends on, for example, firm personnel affected or 
likely to be affected, the associated revenue or profit, the associated 
risks, and the relevant industry.
    h. The effects of any remedial actions that have been implemented, 
tested, and found to be effective.
    Before the annual evaluation date, a firm may implement remedial 
actions that may reduce the severity or pervasiveness of an 
unremediated QC deficiency while not completely addressing it. For a 
firm to take credit for the effects of these remedial actions, they 
would need to be implemented as

[[Page 59374]]

of the evaluation date, and they would need to be tested and found to 
be effective before Form QC is due and filed. For example, in response 
to a QC deficiency related to a problem identified with a firm's audit 
software, the firm designs and implements five remedial actions as of 
the evaluation date. Of those five remedial actions, two remedial 
actions have been tested and found to be effective before Form QC is 
due and filed. When determining the severity and pervasiveness of the 
unremediated QC deficiency, the firm can consider the effects of the 
two remedial actions that have been tested and found to be effective.
    The process flow that follows illustrates how to apply the above 
considerations in reaching one of the three evaluation conclusions in 
paragraph .77.

BILLING CODE 8011-01-C
2. Reporting to the PCAOB
i. Reporting on the Annual Evaluation of the Effectiveness of the QC 
System
    As originally adopted, QC 1000 provides that firms have until 
November 30 each year to report to the PCAOB on Form QC the outcomes of 
their QC system evaluations, based on a fixed evaluation date of 
September 30. This provides firms with 61 days after the evaluation 
date of September 30 to file Form QC. Based on the proposed amendment 
to permit firms to select their own evaluation dates, the Board 
proposed to amend the due date of Form QC in paragraph .79 to 60 days 
after the firm's chosen evaluation date. The Board also proposed to 
amend the Form QC reporting rule, PCAOB Rule 2203A, Report on the 
Evaluation of the Firm's System of Quality Control, and General 
Instruction 3 to Form QC to reflect this proposed amendment (see 
below).
    Commenters generally supported the proposed amendments to paragraph 
.79, Rule 2203A, and Form QC.\243\
---------------------------------------------------------------------------

    \243\ See comment letters from BDO, CFA, Crowe, EY, GT, KPMG, 
Spitters, and VSCPA.
---------------------------------------------------------------------------

    One commenter expressed concern related to the 60-day reporting 
deadline for Form QC, stating that, for many smaller firms, completing 
the annual evaluation of the system of quality control, hiring and 
coordinating external resources, obtaining the necessary internal 
reviews and approvals, and preparing the required report within 60 days 
may not be practicable.\244\ This commenter recommended that the Board 
adopt a more scalable approach, for example, by permitting firms below 
an appropriate threshold to file Form QC within 180 days of their 
evaluation date.\245\ In allowing firms to select their own evaluation 
date, the Board believes it is appropriately providing firms with the 
ability to select a date that works best for their business cycles; 
however, the Board also believes that timely receipt by the PCAOB of 
information contained in Form QC to support the Board's oversight 
activities requires a shorter timeline than this commenter suggested. 
The Board continues to believe that the 60-day filing requirement 
provides firms with sufficient time from the evaluation date to the 
reporting date to complete their evaluation and report to the PCAOB.
---------------------------------------------------------------------------

    \244\ See comment letter from PICPA.
    \245\ See id.
---------------------------------------------------------------------------

    The Board also proposed an amendment to General Instruction 4 to 
Form QC to clarify the reporting period covered by the firm's 
evaluation. As proposed, the reporting period would be the period 
beginning the day after the most recent previous evaluation date and 
ending on the evaluation date, with the following exceptions as to the 
beginning of the reporting period:
    <bullet> If a firm has not previously been required to evaluate its 
QC system under QC 1000, the reporting period is the period beginning 
on the date the firm first incurred an obligation to design, implement, 
and operate a QC system under QC 1000.06.
    <bullet> If a firm was previously required to evaluate its QC 
system under QC 1000, but such obligation lapsed because the firm 
ceased having any obligations under applicable professional and legal 
requirements with respect to one or more engagements, the reporting 
period is the period beginning when the firm subsequently incurred an 
obligation to design, implement, and operate a QC system under QC 
1000.06.
    Under this proposed amendment, the reporting period would generally 
be twelve months long, but it would be longer or shorter if the 
obligation to design, implement, and operate the QC system arises mid-
period (whether by virtue of the effective date of QC 1000 or the 
firm's otherwise becoming subject to the requirement to design, 
implement, and operate a QC system). For example, for a firm that 
selects March 31 as its evaluation date, upon the effective date of QC 
1000 the firm's first evaluation would cover the reporting period from 
December 15, 2026, to March 31, 2028, resulting in a greater-than-15-
month reporting period, with the first Form QC due to be filed no later 
than 60 days following March 31, 2028. This is because as of March 31, 
2027, the firm would not have been subject to the requirement to 
design, implement, and operate a QC system for at least five 
consecutive months (under the five-month threshold in paragraph .77 
discussed above). By contrast, for a firm that selects May 31 as its 
evaluation date and is subject to QC 1000 on the standard's effective 
date, this firm's first evaluation would cover approximately five and a 
half months beginning on December 15, 2026, and ending on May 31, 2027, 
with the first Form QC due to be filed no later than 60 days following 
May 31, 2027.
    The proposed amendment to General Instruction 4 did not draw 
comment.
    The Board is adopting as proposed the amendments to paragraph .79, 
PCAOB Rule 2203A, and Form QC described above.
    One commenter stated that two important elements of Form QC 
reporting would be lost with the removal of the ``major QC deficiency'' 
concept: (1) the requirement to flag whether each unremediated 
deficiency is major, and (2) the narrative required where a major 
deficiency is presumed but determined not to exist.\246\ This commenter 
requested that the Board preserve equivalent signals under the proposed 
evaluation framework and require that firms (1) indicate, for each 
unremediated QC deficiency, whether the firm assessed it as severe, and 
(2) explain the basis for any determination that severe deficiencies do 
not, individually or in combination, render the QC system not 
effective.\247\ QC 1000 continues to require that firms report all 
unremediated QC deficiencies as of the evaluation date on Form QC, 
regardless of the conclusion reported under paragraph .80a. 
Accordingly, a firm's Form QC reporting must include any unremediated 
QC deficiencies identified as of the evaluation date, including QC 
deficiencies that were determined not to be severe or pervasive. The 
Board continues to believe that reporting of all unremediated QC 
deficiencies will inform various aspects of the Board's oversight 
activities. Upon receipt of a Form QC, the PCAOB will have the ability 
to perform further inquiries of a firm regarding any of the information 
provided. Additionally, the firm is required to document under 
paragraph .82d the basis for the conclusion reached under paragraph 
.77, which would include the firm's evaluation of the severity and 
pervasiveness of unremediated QC deficiencies, and this information 
would be available to the PCAOB in connection with its oversight 
activities, including inspections.\248\

    \247\ See id.
    \248\ See PCAOB Rule 4000(b), General.
---------------------------------------------------------------------------

    Based on the amendments described above, the Board is adopting 
additional conforming amendments to paragraph .80 and Form QC, 
substantially as proposed.\249\ The Board is also adopting amendments 
to paragraph .80 and Form QC to replace the language ``the issuance of 
unsupported opinions'' with ``significant engagement deficiencies,'' 
consistent with the amendments to QC 1000.68a described above, as 
proposed.
---------------------------------------------------------------------------

    \249\ Note 1 to Item 3.2 within Form QC is amended to include a 
reference to the evaluation date. Also, language related to Exhibit 
3.2.b in Part VII of Form QC is amended to refer to individuals 
``assigned'' operational responsibility and accountability for the 
firm's QC system as a whole.
---------------------------------------------------------------------------

ii. Reporting Changes to the Firm's Evaluation Date
    Under the amendments to QC 1000.77, as discussed above, each firm 
selects its own evaluation date. The Board proposed that any change in 
the

[[Page 59376]]

evaluation date, together with a brief statement of the firm's 
rationale for making the change, be reported on Form QC within 30 days 
after the firm's decision. The Board believes this information would 
inform the timing of the Board's oversight efforts.
    To codify this requirement, the Board proposed to recaption Rule 
2203A as ``Reporting on the Evaluation of the Firm's System of Quality 
Control,'' amend paragraph (a) of Rule 2203A to require notification of 
a change in the evaluation date on Form QC, and amend paragraph (b) of 
Rule 2203A to require such notification to be filed no later than 30 
days after the firm's decision to change the evaluation date.
    Relatedly, the Board proposed to amend Form QC to add a new Item 
1.2, Change to the Evaluation Date, for providing notice of a change to 
the evaluation date, including the new evaluation date and a brief 
statement of the rationale for making the change. Additional language 
was also proposed to be added to General Instruction 3 to explain that 
Form QC is required to be filed no later than 30 days after the firm's 
decision to change the evaluation date and that a notification of 
change in the evaluation date need only include a completed Part I and 
the signed certification in Part V of Form QC.
    Several commenters expressed support for the proposed reporting 
changes regarding the firm's evaluation date.\250\ Some commenters 
requested additional clarifications regarding (1) whether the firm 
should use business days or calendar days when calculating the deadline 
for submitting Form QC to notify the Board of a new evaluation date, 
(2) changes in the firm's evaluation date (for example, due to mergers 
or acquisitions), and (3) changing an evaluation date after the first 
year of implementation.\251\ Because the deadline for submitting Form 
QC is greater than seven days, the 30-day submission deadline when 
providing notice of a new evaluation date is based on calendar days, 
taking into account the exception that applies if the last day of the 
30-day period is a Saturday, Sunday, or Federal legal holiday.\252\ 
Additionally, the standard does not limit when a firm can change its 
evaluation date, but a change to a firm's evaluation date would likely 
involve significant changes to many aspects of the firm's QC processes, 
so a firm will need to consider the implications to its QC system of 
making such a change. As noted above, if the firm decides to change its 
evaluation date, the change must be reported on Form QC within 30 days 
after the firm's decision, together with a brief statement of the 
firm's rationale for the change.

holiday, the deadline for filing Form QC shall be the next day that 
is not a Saturday, Sunday, or Federal legal holiday.
---------------------------------------------------------------------------

    The Board is adopting these amendments as proposed.

Documentation

    As originally adopted, QC 1000 provides firms until December 14 
following the firm's annual evaluation to assemble for retention a 
complete and final set of QC documentation.
    The Board proposed amendments to QC 1000.84 to clarify that the QC 
documentation should be completed and retained ``in a manner that 
permits timely retrieval,'' rather than ``assembled for retention,'' by 
the QC documentation completion date. Documentation is considered 
timely retrievable when it is made available in a manner that does not 
hinder an experienced auditor's ability to understand the design, 
implementation, and operation of the QC system during a particular 
evaluation period in accordance with QC 1000.83b and the accompanying 
note. In addition, in conjunction with the amendments to paragraphs .77 
and .79 of QC 1000, which permit firms to select their own evaluation 
date and require them to report on that evaluation no later than 60 
days after that date, the Board proposed to amend the QC documentation 
completion date to be 14 days after Form QC is filed (or due to be 
filed, if earlier).
    Many commenters supported the proposed amendments to paragraph .84 
\253\ but some stated they continue to have concerns regarding the 
scope of the documentation requirements, particularly the extent of 
documentation required to be retained.\254\ One of these commenters 
raised concerns regarding the clarity and practical application of 
``timely retrieval of documentation'' that is not maintained in the 
quality monitoring tool and stated that firms would otherwise need to 
identify, monitor, and retain documentation across a broad range of 
decentralized locations.\255\ One commenter stated that, while they did 
not object to the proposed amendments, the proposed amendments did not 
address a key issue related to real-time systems, namely, that such 
systems may not allow for the reconstruction of information back to a 
specific point in time unless versions are archived or captured 
otherwise.\256\ Another commenter did not object to the proposed 
amendments allowing firms to retain QC documentation within their 
original systems of record, provided it remains promptly 
retrievable.\257\

    Two commenters expressed uncertainty as to the nature of the 
documentation required to be retained, for example, emails or other 
documentation that relate to QC processes.\258\ One of these commenters 
requested clarification that other evidence of the underlying 
documentation, such as system-generated reports or other reproducible 
outputs, would meet the documentation requirements.\259\ This commenter 
stated that the release text in the supplemental request for comment 
indicated that firms were expected to retrieve documentation from live 
systems ``as it existed at the time that it was considered complete,'' 
which might not be feasible with continuously updating systems and 
would appear to reintroduce the same operational challenges the 
proposed amendment was intended to alleviate.\260\ The other commenter 
stated that it was unclear as to how to address documentation residing 
in systems or applications that have been replaced during the 
evaluation period.\261\

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

    Two commenters requested changes to documentation retention 
requirements, including limiting the retention requirement to evidence 
generated through the firm's own monitoring activities and reducing the 
volume of documentation required to be retained for five years.\262\ 
Another commenter stated that the proposed amendments to paragraph .84 
do not clarify whether firms are required to retain evidence of every 
instance of every response, or just those instances that were tested to 
support the firm's QC system evaluation.\263\
---------------------------------------------------------------------------

    \262\ See comment letters from EY and PICPA.
    \263\ See comment letter from RSM.
---------------------------------------------------------------------------

    After consideration of the comments received, the Board is adopting 
the amendments to paragraph .84 as proposed.

[[Page 59377]]

    The proposed amendments clarify that firms are afforded flexibility 
in determining the manner(s) in which they retain documentation. 
Specifically, the proposed amendment to this documentation requirement 
clarifies that firms are permitted to maintain their QC documentation 
in the original system(s) of record, or in any manner or combination of 
manners they deem appropriate, and do not have to undergo the 
potentially costly and time-consuming process of transferring and 
assembling documentation from various source systems into a single 
system for archiving and retention. In addition, the Board believes 
that the proposed amendments clarify that it is not necessary for the 
firm to implement new technology solutions for the purpose of meeting 
QC 1000's documentation requirements because the amendment makes clear 
that documentation can continue to exist within the systems in which it 
originated or is used as long as it remains available for retrieval, 
e.g., for purposes of subsequent monitoring or inspection.
    The Board believes the proposed amendments should provide 
operational relief for firms when maintaining documentation of their QC 
systems. If circumstances arise, such as when a firm decides to replace 
an existing system or determines that the decentralization of a firm's 
QC documentation is too broad, then a firm can maintain the required 
documentation of its QC system in the manner that is most appropriate 
for the firm--provided that the documentation is retained in a manner 
that permits timely retrieval. QC 1000 does not impose requirements on 
firms with respect to the specific systems in which QC documentation 
must be retained or the number of systems that retain a firm's QC 
documentation.
    The Board acknowledges that a firm's QC system is continuously 
operating and the firm might not have the capability to take snapshots 
of system-based evidence at a point in time or for the systems to be 
locked down to allow for documentation to be archived. Therefore, the 
proposed amendment requires that the documentation be retained in a 
manner that permits timely retrieval, but does not specify a particular 
approach. Firms are not expected to continuously or periodically take 
snapshots of their system's data to meet this amended requirement. 
However, given that QC documentation may reside within live systems, 
the firm will need to be able to access and timely retrieve 
documentation sufficient to demonstrate compliance with paragraphs 
.81-.83 for the applicable evaluation as of the time the documentation 
was considered complete. If certain information related to the 
operation of the firm's QC systems is relevant or needed for the firm 
to monitor and evaluate whether a quality response operated as 
intended, then the firm would need to retain that information.
    In determining the nature of the QC documentation to be retained, a 
firm may identify aspects within the QC system for which the evidence 
required to demonstrate that the QC system was designed, implemented, 
or operating effectively may not entail retention of all information 
that the system produces in its daily operation. For example, rather 
than retaining printed copies or screenshots of the restricted entity 
list after each change, the firm may produce the current listing along 
with a system-generated report listing the changes after a specified 
date.
    As noted in the QC 1000 2024 adopting release, in light of the 
scope of the Board's statutory mandate, the Board's inspection 
procedures cannot be limited to quality responses (and, to the extent 
applicable, samples of the operation of quality responses) that the 
firm chose to monitor in the period.\264\ On the contrary, firms will 
be expected to provide evidence of the operating effectiveness of any 
quality responses selected for inspection.
---------------------------------------------------------------------------

    \264\ See PCAOB Rel. No. 2024-005, at 283.
---------------------------------------------------------------------------

    As originally adopted, QC 1000 includes a requirement that the firm 
retain QC documentation for seven years from the QC documentation 
completion date, unless a longer period is required by law.
    The Board proposed to amend paragraph .86 to reduce the QC 
documentation retention period to five years from the QC documentation 
completion date.
    Many commenters supported the proposed amendment to paragraph 
.86,\265\ but some of these commenters encouraged the Board to consider 
whether the retention period could be further reduced,\266\ with two of 
them suggesting that a three-year retention period may be 
sufficient.\267\ Another commenter stated that a single retention 
period applied to all QC documentation may not be necessary and 
encouraged consideration of an approach whereby documentation 
supporting the firm's evaluation of its system of quality control be 
retained for a period of five years, while broader system documentation 
could be subject to a shorter retention period, such as three 
years.\268\ Another commenter suggested that the Board should clarify 
whether the same documentation expectations apply to both the firm's 
overall evaluation and conclusion on its QC system and the day-to-day 
execution of individual quality responses.\269\ The commenter added 
that documentation supporting the firm's evaluation and conclusion is 
generally more centralized and better suited to a five-year retention 
period, whereas execution-level documentation is often more detailed 
and may reside in several systems that change over time.\270\ One 
commenter cited specific concerns relating to the need to update 
systems and maintain system licenses for five years for the purpose of 
retaining records,\271\ and another commenter stated that there are 
still significant costs associated with retaining the required data for 
five years.\272\

    One commenter stated that an argument for requiring a seven-year 
retention period is that the retention period for QC documentation 
should be no shorter than that of the audit documentation requirements 
included in AS 1215, Audit Documentation.\273\ However, the commenter 
also stated that if that argument is not persuasive, then the minimum 
retention period should be as low as possible based on users' needs, 
including regulators', and in that context five years sounded 
excessive.\274\ Another commenter stated that a consideration for 
retaining the seven-year requirement could be that some U.S. Federal 
and state tax retention periods are a minimum of seven years.\275\ 
Another commenter questioned whether it would be preferable to use the 
term ``applicable professional and legal requirements'' instead of 
``law'' in the phrase ``unless a longer period of time is required by 
law.'' \276\

    Another commenter asked the Board to reconsider the proposed 
reduction from seven years to five years, stating that, under a five-
year QC documentation retention period, engagement workpapers would 
remain available to inspection and enforcement for up to two years 
after the QC records

[[Page 59378]]

that contextualize them--such as monitoring results, root cause 
analyses, and remediation evidence--could have been lawfully 
destroyed.\277\ The commenter said that, at a minimum, the retention 
period must remain long enough for the PCAOB to identify deficiency 
patterns that only become visible across more than one inspection 
cycle.\278\ The commenter further stated that QC documentation relevant 
to an identified deficiency, or to an open inspection or enforcement 
matter, should be retained until the matter is resolved.\279\
---------------------------------------------------------------------------

    \277\ See comment letter from CFA.
    \278\ See id.
    \279\ See id.
---------------------------------------------------------------------------

    The Board has considered the costs and benefits of various 
retention periods, including both retaining a seven-year retention 
period to be consistent with audit documentation requirements under AS 
1215 and adopting a retention period shorter than five years. The Board 
believes that a five-year retention period appropriately balances the 
objective of reducing unnecessary retention costs with the need to 
preserve documentation relevant to the PCAOB's oversight activities. In 
particular, the Board believes that a retention period shorter than 
five years could adversely affect the PCAOB's ability to carry out its 
oversight responsibilities and evaluate information relating to a 
firm's QC system over time--and carrying out our responsibilities may 
require access to information beyond that supporting the firm's 
evaluation and conclusion.
    The Board also does not believe that adopting multiple retention 
periods for different categories of QC documentation would be 
appropriate. QC 1000 contemplates an integrated and interrelated system 
of quality control, and the documentation required by paragraphs 
.81-.83 is intended to support an understanding of the design, 
implementation, and operation of that system as a whole. Applying 
different retention periods to different categories of QC documentation 
could introduce unnecessary complexity and inconsistency and diminish 
the usefulness of documentation in understanding the operation of the 
firm's QC system over time.
    Regarding commenter concerns relating to the need to update systems 
or maintain system licenses over time, as discussed above in connection 
with the proposed amendment to paragraph .84, QC 1000 does not 
prescribe the systems in which QC documentation should be retained or 
the number of systems that may be used to retain such documentation. 
Firms may determine the most appropriate retention approaches based on 
their own facts and circumstances, provided that the documentation of 
the firm's QC system can be timely retrieved and is retained for five 
years from the QC documentation completion date unless a longer period 
of time is required by law.
    QC 1000 acknowledges that firms may be subject to laws requiring 
retention of QC documentation for a longer period than what the 
standard requires. In such situations, firms would be required to 
retain documentation for that longer period. This approach is 
consistent with that used in AS 1215, which similarly recognizes that 
longer retention periods required ``by law'' may override the period 
specified in the standard. The Board acknowledges the comment 
suggesting use of a longer period whenever required by applicable 
professional and legal requirements, but the Board has determined to 
follow the approach of AS 1215 for consistency.
    After consideration of the comments received, the Board is adopting 
this amendment as proposed.

Requests for Implementation Guidance and Additional Commenter Feedback

1. Requests for Implementation Guidance
    Commenters requested additional guidance on QC 1000, including 
specific examples and general guidance related to the proposed 
amendments, noting that such guidance would help promote consistent and 
effective implementation of the standard.\280\ While some of these 
commenters acknowledged and appreciated the staff's ongoing engagement 
with firms,\281\ a few commenters also requested that the Board 
memorialize the substance of those discussions into interpretive 
guidance available to all firms, suggesting that doing so would further 
enhance consistency and effectiveness in implementing QC 1000.\282\

concerns regarding the confidentiality of information submitted through 
Form QC, particularly information relating to identified deficiencies, 
root causes, remediation strategies, governance matters, and other 
aspects of a firm's system of quality control, and suggested that 
additional clarity on certain matters would provide firms with greater 
certainty regarding the treatment of highly sensitive quality
