Independent Audit Committees for Registered Investment Companies
SEC Rule 32a-4, codified at 17 C.F.R. § 270.32a-4 under the Investment Company Act of 1940, exempts a registered management investment company or registered face-amount certificate company from the requirement of Section 32(a)(2) of the Act — which mandates that the selection of the company's independent public accountant be submitted for ratification or rejection at the next succeeding annual meeting of shareholders — provided the fund has established an audit committee composed solely of directors who are not interested persons of the company with responsibility for overseeing the fund's accounting and auditing processes, has adopted a written charter setting forth that audit committee's structure, duties, powers, and methods of operation, and maintains and preserves a copy of that charter permanently in an easily accessible place.
Rule 32a-4 is the governance mechanism through which the overwhelming majority of registered management investment companies avoid the logistical burden and commercial disruption of submitting their auditor selection to shareholder ratification annually — permitting the fund's independent audit committee to exercise continuing, substantive oversight of the fund's accounting and auditing processes in substitution for the shareholder vote that Section 32(a)(2) would otherwise require.
The rule reflects the Investment Company Act framework's consistent approach to independent director governance — vesting governance functions that would otherwise require shareholder involvement in committees of genuinely independent directors whose fiduciary duties and governance expertise enable them to exercise the oversight function more efficiently and effectively than an annual shareholder ratification process would achieve.
Overview and Regulatory Purpose
Section 32(a)(2) of the Investment Company Act requires that the selection of a registered management investment company's independent public accountant — the auditor responsible for auditing the fund's financial statements, an engagement whose scope, quality, and independence are central to the accuracy of the financial reporting that investors receive through the fund's annual and semi-annual reports — be submitted for ratification or rejection at the next succeeding annual meeting of shareholders after the accountant's selection.
This shareholder ratification requirement reflects the Investment Company Act's general philosophy of involving shareholders in significant governance decisions affecting their investment, treating the selection of an independent auditor as a decision of sufficient importance to warrant shareholder input rather than being left entirely to the discretion of fund management.
The practical challenge that Rule 32a-4 addresses is that annual shareholder ratification of the auditor selection — while defensible in principle — imposes substantial operational costs on registered funds without providing commensurate governance benefit in the specific circumstances of the modern investment company structure.
The overwhelming majority of registered fund shareholders are individual retail investors who hold fund shares not for governance purposes but for investment return — investors who are unlikely to engage meaningfully with an annual proxy question about auditor selection, whose aggregate voting patterns on such questions are typically driven by proxy advisory firm recommendations rather than independent investor analysis, and whose practical ability to influence auditor selection through the vote mechanism is limited by the information asymmetry between retail shareholders and the audit committee members who have specific knowledge of the auditor's performance.
In this context, the substantive governance benefit of annual shareholder ratification is modest, while the administrative costs of preparing and distributing proxy materials for an annual auditor ratification vote are substantial.
Rule 32a-4 substitutes a more effective governance mechanism — a standing audit committee of independent directors with specific authority over accounting and auditing processes and with the expertise, information access, and ongoing engagement necessary to evaluate auditor performance on a continuing rather than annual vote basis — for the annual shareholder ratification requirement. By conditioning the exemption on the existence of a written charter specifying the audit committee's authority and responsibilities, the rule ensures that the substituted governance mechanism is institutionalised and enforceable rather than informal and discretionary.
Statutory Authority and Rulemaking History
Rule 32a-4 derives its statutory authority from Section 32(a)(2) of the Investment Company Act — the shareholder ratification requirement from which the rule provides exemption — and from Section 38(a)'s general rulemaking authority. Section 32(a)(2)'s specific grant of Commission authority to exempt funds from the shareholder ratification requirement by rule is the direct statutory basis for Rule 32a-4's standing exemption.
Rule 32a-4 has been in Part 270 for several decades, with its core structure — audit committee exemption, charter requirement, permanent record preservation — having been in place since the rule's early iterations. The most significant recent amendment was adopted as part of the Investment Company Governance rulemaking in 2004, which updated Rule 32a-4's conditions to align with the fund governance standards framework that the rulemaking established for the ten Exemptive Rules identified in Rule 0-1(a)(7), effective January 15, 2006. The February 12, 2026 Federal Register Paperwork Reduction Act notice confirmed that the rule remains operative in its current form without pending amendments. No substantive changes have been made to Rule 32a-4's operative provisions up to the present time.
Key Provisions and Operative Requirements
Rule 32a-4 establishes three conditions that must simultaneously be satisfied for a registered management investment company or face-amount certificate company to be exempt from Section 32(a)(2)'s shareholder ratification requirement.
Rule 32a-4(a) — the audit committee composition condition — requires that the fund's board of directors has established a committee composed solely of directors who are not interested persons of the company, that has responsibility for overseeing the fund's accounting and auditing processes. The composition requirement — all audit committee members must be independent directors — is more stringent than the general board composition standards of the Investment Company Act, which require only that a majority of directors be independent. This heightened independence requirement for the audit committee reflects the specific governance sensitivity of the accounting and auditing oversight function — a fund's financial reporting quality depends critically on the auditor's genuine independence from management, and an audit committee whose members have any conflicting interest with the fund's management would compromise exactly the independence dimension that the auditor selection oversight function is most fundamentally designed to protect.
The audit committee's responsibility for overseeing the fund's accounting and auditing processes encompasses a broad and substantive governance mandate that goes well beyond merely approving the auditor selection. Audit committee oversight in the registered fund context includes: reviewing the scope and results of the annual audit; evaluating the auditor's independence from the fund's management and investment adviser; assessing the quality and adequacy of the fund's internal controls over financial reporting and their interaction with the Rule 30a-3 controls and procedures framework; reviewing the accounting policies applied in the fund's financial statements; and managing the audit committee's relationship with the independent auditor through direct communication channels that bypass management — ensuring that the auditor can communicate concerns directly to the audit committee without management filtering or suppressing those communications.
Rule 32a-4(b) — the audit committee charter requirement — requires that the fund's board of directors has adopted a charter for the audit committee that sets forth the committee's structure, duties, powers, and methods of operation, or has set forth such provisions in the fund's charter or bylaws. The written charter requirement gives the audit committee's authority institutional form — transforming the governance mandate from an informal understanding of the independent directors' role into a formal, documented governance instrument whose terms are enforceable and whose content provides a clear framework for assessing whether the audit committee is discharging its oversight responsibilities. The charter must address the four specified elements — structure, duties, powers, and methods of operation — with sufficient specificity to enable both the audit committee members and external reviewers to assess whether the committee's functioning is consistent with its charter obligations.
In practice, registered fund audit committee charters typically address: the committee's composition and qualification requirements; the committee's responsibilities regarding pre-approval of audit and non-audit services; procedures for receiving and addressing reports from the independent auditor; the committee's role in reviewing annual and semi-annual financial statements before transmittal to shareholders; procedures for considering complaints regarding accounting, internal controls, and auditing matters; the committee's authority to engage independent counsel and other advisers; and the committee's reporting obligations to the full board of directors. These charter provisions collectively define the audit committee's governance architecture in a manner that enables the committee to discharge the accounting and auditing oversight responsibility that Rule 32a-4(a) requires and that substitutes for the shareholder ratification process.
Rule 32a-4(c) — the permanent record preservation condition — requires that the fund maintains and preserves permanently in an easily accessible place a copy of the audit committee's charter and any modification to the charter. This preservation condition creates a permanent documentary record of the governance instrument whose existence is the foundation of the Section 32(a)(2) exemption — enabling the Commission's examination staff to verify that the audit committee charter was formally adopted, to assess the adequacy of the charter's coverage of the required structural and operational elements, and to track modifications to the charter over time.
The permanent preservation requirement is one of the most distinctive recordkeeping obligations in the Investment Company Act's governance framework. Most records required by Investment Company Act rules must be maintained for specified periods — typically five or six years — after which they may be disposed of. The permanent preservation requirement for the audit committee charter reflects the Commission's assessment that this governance document is foundational to the fund's ongoing eligibility for the Section 32(a)(2) exemption and that its permanent availability is necessary for the integrity of the exemptive framework.
Scope of Application
Rule 32a-4 applies to registered management investment companies — encompassing open-end mutual funds, ETFs, closed-end funds, interval funds, and BDCs — and to registered face-amount certificate companies. The rule is not mandatory — a registered fund may choose to satisfy Section 32(a)(2) by submitting its auditor selection to shareholders for ratification annually rather than establishing an audit committee under Rule 32a-4. In practice, however, virtually all registered management investment companies rely on Rule 32a-4's exemption, since the costs of annual shareholder ratification substantially exceed the costs of maintaining a compliant audit committee charter and the governance benefits of the audit committee oversight model are substantively superior to those of an annual shareholder vote.
ETFs registered as management investment companies are subject to Rule 32a-4 in the same manner as conventional mutual funds — the ETF's board must establish an all-independent audit committee with a written charter and must preserve that charter permanently to be exempt from the annual auditor ratification requirement. The ETF structure's distinctive feature of secondary market trading does not affect the applicability of Rule 32a-4's audit committee governance conditions, since those conditions address the fund's internal financial reporting oversight rather than its capital markets characteristics.
Relationship to Related Rules and Regulations
Rule 32a-4's audit committee governance framework is directly connected to Rule 30a-3's controls and procedures framework — the Sarbanes-Oxley-derived internal control assessment regime that requires registered management investment companies to maintain and evaluate disclosure controls and procedures and internal control over financial reporting. The audit committee that Rule 32a-4 establishes is the primary governance body through which the fund's board exercises oversight of the Rule 30a-3 internal control framework — receiving management's and the auditor's assessments of control adequacy, reviewing management's evaluation of disclosure controls, and providing the board-level oversight infrastructure within which the Rule 30a-3 certification and assessment process operates.
Rule 32a-4's all-independent audit committee condition relates directly to the independence standards of the Investment Company Act generally, and to the fund governance standards of Rule 0-1(a)(7) specifically. The audit committee's composition requirement — all members must be non-interested persons — is more stringent than Rule 0-1(a)(7)'s fund governance standards, which require only 75% independence for the full board. The audit committee's heightened independence standard reflects the specific sensitivity of the financial oversight function to any compromise of director independence.
Rule 38a-1's compliance programme framework requires that registered fund compliance programmes specifically address Rule 32a-4 compliance — including the procedures for maintaining the audit committee charter in compliance with the rule's composition, charter content, and permanent preservation conditions. The CCO's annual report to the board required by Rule 38a-1 must address any material compliance matters relating to the audit committee's composition and charter compliance.
Amendment History and Regulatory Evolution
Rule 32a-4's operative framework has been substantively stable since the 2006 Investment Company Governance rulemaking update, with no further amendments adopted since that time. The February 2026 Paperwork Reduction Act extension confirms the Commission's ongoing maintenance of the rule's information collection framework without pending regulatory changes.
The broader audit committee governance landscape has evolved significantly around Rule 32a-4 through the development of best practice standards for investment company audit committees — particularly in the wake of the Sarbanes-Oxley Act's comprehensive audit committee governance requirements for Exchange Act reporting companies — and through the Commission's and PCAOB's enhanced engagement with the quality of registered fund audits. These developments have raised expectations for audit committee effectiveness and engagement beyond the formal minimum conditions of Rule 32a-4, but the rule's own operative provisions have remained unchanged.
Enforcement Context and SEC Action Patterns
Rule 32a-4 enforcement concentrates on failures of the three operative conditions — funds that rely on the Section 32(a)(2) exemption without having formally adopted an audit committee charter, funds whose audit committee includes one or more directors who are interested persons of the fund, and funds that have failed to maintain the audit committee charter in permanent, easily accessible form. These compliance failures are typically identified through the Commission's examination programme rather than through investor complaints, since the conditions of Rule 32a-4 govern internal governance structures rather than disclosures visible to shareholders.
The Commission's examination programme specifically reviews audit committee charter compliance as part of its assessment of registered fund governance and financial reporting oversight infrastructure, with attention to whether the charter adequately addresses each of the four required elements — structure, duties, powers, and methods of operation — and whether the audit committee's actual functioning is consistent with its charter obligations.
Examination Relevance and Key Takeaways
Rule 32a-4 is examined at the Series 65 level as the audit committee governance framework enabling registered management investment companies to substitute independent audit committee oversight for Section 32(a)(2)'s annual shareholder auditor ratification requirement. The three conditions — all-independent audit committee composition, written charter addressing structure, duties, powers, and methods of operation, and permanent preservation of the charter — are the primary examination content. The distinction between the audit committee's all-independent composition requirement and the 75% independence standard of Rule 0-1(a)(7)'s fund governance standards is a useful comparison point for examination candidates understanding the differentiated independence requirements applicable to different board functions.
The key points to retain are these. Rule 32a-4 exempts registered management investment companies and face-amount certificate companies from Section 32(a)(2)'s requirement that the auditor selection be submitted to shareholders for annual ratification, provided three conditions are simultaneously satisfied: the fund's board has established an audit committee composed solely of non-interested directors with responsibility for overseeing accounting and auditing processes; the board has adopted a written charter for the audit committee specifying its structure, duties, powers, and methods of operation; and the fund permanently preserves a copy of the charter and any modifications in an easily accessible place. Rule 32a-4's all-independent audit committee condition is more stringent than the 75% independence standard of Rule 0-1(a)(7)'s fund governance framework. The rule applies to all registered management investment companies including ETFs. Virtually all registered management investment companies rely on Rule 32a-4's exemption rather than submitting auditor selection to annual shareholder ratification. Rule 32a-4 was last substantively amended in connection with the 2006 Investment Company Governance rulemaking. No changes have been made to its operative provisions up to the present time.
