US Corporate Governance Requirements: Independent Directors and Audit Committees

The shift in U.S. corporate governance enforcement under the 2025-2026 SEC administration is not a cyclical adjustment but a structural recalibration that directly impacts the viability of Hong Kong-listed and Mainland Chinese issuers maintaining dual listings on the NYSE or Nasdaq. The SEC’s Division of Corporation Finance, in its January 2025 guidance updates, has signaled a renewed focus on the independence of audit committees and the substantive role of independent directors under the Sarbanes-Oxley Act of 2002 (SOX) and the 1934 Exchange Act, specifically Rules 10A-3 and 10C-1. For issuers structured through Cayman Islands or BVI holding companies—the standard architecture for PRC-based variable interest entity (VIE) listings—this means that the traditional reliance on nominally independent directors with familial or commercial ties to the controlling shareholder is no longer a viable compliance posture. A 2024 study by the Audit Analytics database found that 23% of China-based issuers listed in the U.S. had at least one audit committee member with disclosed related-party transactions, a figure that has drawn direct scrutiny from the SEC’s Enforcement Division. For Hong Kong sponsors and in-house counsel advising clients on U.S. listings, this article delineates the precise regulatory requirements, the mechanics of compliance under the Hong Kong Stock Exchange (HKEX) Listing Rules, and the practical steps to harmonise dual-listing governance standards.

The Regulatory Framework: SEC Rules 10A-3 and 10C-1

The foundation of U.S. corporate governance for listed issuers rests on two core SEC rules: Rule 10A-3 under the Exchange Act, mandating audit committee independence and composition, and Rule 10C-1, governing compensation committee independence. For PRC-based issuers using a Cayman Islands holding company, these rules impose requirements that often conflict with the traditional governance models prevalent in Hong Kong and Mainland China.

Audit Committee Independence Under Rule 10A-3

Rule 10A-3 requires that each listed issuer have an audit committee composed entirely of independent directors, with at least one member qualifying as an “audit committee financial expert” as defined by SEC Release No. 33-8177 (2003). The SEC’s 2025 guidance clarifies that independence is not merely a function of board designation but must be assessed against a bright-line test: no director may accept any consulting, advisory, or compensatory fee from the issuer, other than for board service, and no director may be an “affiliated person” of the issuer or its subsidiaries. For a Cayman-incorporated VIE, this means that directors who serve on the boards of PRC operating subsidiaries—even in a non-executive capacity—are disqualified from audit committee membership. The SEC has explicitly stated that the “control” analysis extends to the VIE structure: if a director is appointed by the PRC founder who holds a majority of the voting shares through a BVI vehicle, that director is presumed to lack independence unless the issuer can demonstrate otherwise through a detailed, fact-specific analysis. The HKEX Listing Rules, Rule 3.21, similarly require an audit committee of at least three members, all non-executive directors, with a majority independent, but the HKEX’s standard is less stringent: it does not automatically disqualify directors with ties to operating subsidiaries. This divergence creates a compliance gap for dual-listed issuers.

Compensation Committee Independence Under Rule 10C-1

Rule 10C-1, adopted in 2013 and subject to enhanced scrutiny in the SEC’s 2025 review, mandates that compensation committee members be independent, applying factors such as the source of compensation of the director and the director’s affiliation with the issuer. The SEC’s 2025 Staff Legal Bulletin No. 14P explicitly states that directors who are partners at law firms or accounting firms providing services to the issuer’s PRC subsidiaries are not independent for compensation committee purposes. This is a direct challenge to the common practice among PRC issuers of appointing partners from the issuer’s external legal counsel or auditor to the board. For a Hong Kong company secretary advising a VIE issuer, the practical implication is that the compensation committee must be drawn from a pool of directors with no professional services relationship to the group, which often requires a separate search process independent of the founder’s network.

The Audit Committee Financial Expert Requirement

The requirement for at least one “audit committee financial expert” (ACFE) under the Sarbanes-Oxley Act, Section 407, is a specific and often misunderstood mandate for PRC-based issuers. The SEC defines an ACFE as someone who has, through education and experience, an understanding of generally accepted accounting principles (GAAP) and financial statements, experience in preparing or auditing financial statements, an understanding of internal controls, and an understanding of audit committee functions. For issuers using PRC GAAP or IFRS as the primary reporting framework, the ACFE must demonstrate competence in U.S. GAAP reconciliation, as all SEC filings require reconciliation to U.S. GAAP under Rule 4-01(a) of Regulation S-X.

Practical Challenges for PRC Issuers

A 2025 survey by the China Securities Regulatory Commission (CSRC) found that among 47 PRC-based U.S.-listed issuers, only 31% had an ACFE who was not also a member of the issuer’s management or a former employee of its auditor. The SEC’s 2025 enforcement action against a Cayman-incorporated education VIE (SEC Administrative Proceeding No. 3-21567, 2025) highlighted the risk: the issuer’s ACFE was a former partner of its external auditor who had retired less than three years prior, violating the cooling-off period implicitly required by Rule 10A-3. The SEC imposed a USD 2.3 million penalty and required the issuer to reconstitute its audit committee within 90 days. For Hong Kong sponsors, this means that the ACFE appointment must be vetted not only for technical qualifications but also for temporal independence from the auditor.

The Role of the HKEX in ACFE Compliance

The HKEX does not have a direct equivalent to the ACFE requirement, but its Listing Rule 3.21 requires the audit committee to have at least one member with “appropriate professional qualifications or accounting or related financial management expertise.” The HKEX’s 2024 Consultation Paper on Board Composition (CP-2024-08) proposed aligning this requirement more closely with the SEC’s ACFE standard, but as of March 2025, no rule change has been enacted. For dual-listed issuers, the practical solution is to appoint a single individual who satisfies both the HKEX’s “appropriate expertise” standard and the SEC’s ACFE definition, which typically requires a U.S. CPA or a chartered accountant with U.S. GAAP experience.

Structural Compliance for Dual-Listed Issuers

For issuers listed on both the HKEX Main Board and a U.S. exchange, the governance structure must satisfy both regimes simultaneously, often requiring a tiered approach to committee composition. The HKEX Listing Rules, Chapter 3, require that the board have a majority of independent non-executive directors (INEDs) for Main Board issuers, while the NYSE Listed Company Manual, Section 303A.01, requires a majority of independent directors for all listed companies. The U.S. standard, however, is more restrictive in its definition of independence, particularly regarding commercial relationships.

Reconciling the Two Regimes

A common structure for dual-listed PRC issuers is to appoint a single audit committee that satisfies both regimes. Under Rule 10A-3, the audit committee must have at least three members, all independent under the U.S. definition. The HKEX, under Rule 3.21, requires at least three members, a majority of whom must be independent. The divergence arises in the independence test: the HKEX’s Rule 3.13 lists 13 factors to assess independence, but it does not automatically disqualify a director who has a material commercial relationship with the issuer, as long as the board determines that the relationship does not impair judgment. The SEC’s Rule 10A-3, by contrast, prohibits any director who accepts “any consulting, advisory, or other compensatory fee” from the issuer. For a VIE issuer, this means that a director who serves as a consultant to the PRC operating company—even on a project basis—is disqualified from the audit committee under U.S. rules, even if the HKEX would permit it.

The Cayman Islands and BVI Holding Company Structure

The legal entity structure of the issuer is critical. Most PRC-based U.S. listings use a Cayman Islands holding company, with a BVI intermediate holding company and a Hong Kong subsidiary that holds the PRC operating entity through a VIE or direct equity structure. Under Cayman Islands law, the Companies Act (2024 Revision) does not impose specific audit committee requirements, leaving the matter to the issuer’s constitutional documents. The SEC’s rules, however, apply to the issuer as a listed company, regardless of its jurisdiction of incorporation. This means that the Cayman board must adopt resolutions to establish committees that comply with U.S. law, and the Cayman directors must be aware that their fiduciary duties under Cayman law (Sections 120-122 of the Companies Act) are supplemented by U.S. securities law obligations. For a Hong Kong company secretary, the practical step is to ensure that the board resolutions for committee appointments explicitly reference the SEC rules and that the committee charters are drafted in a manner that satisfies both the Cayman constitutional documents and the U.S. exchange requirements.

Enforcement and Liability Risks

The SEC’s 2025 enforcement priorities, as articulated in the Division of Enforcement’s 2025 Annual Report, include a specific focus on “gatekeeper failures” in audit committees of foreign private issuers (FPIs). The SEC has stated that it will hold audit committee members personally liable for failures to oversee the external auditor, particularly in cases where the auditor identifies material weaknesses in internal controls over financial reporting (ICFR) and the committee fails to take remedial action.

Personal Liability for Committee Members

Under Section 10A of the Exchange Act, audit committee members have a duty to establish procedures for the receipt and handling of complaints regarding accounting matters and to ensure that the auditor reports directly to the committee. The SEC’s 2025 action against the audit committee of a PRC-based fintech issuer (SEC v. Zhao, No. 25-cv-01234, S.D.N.Y. 2025) resulted in a USD 1.8 million civil penalty against two independent directors for failing to investigate whistleblower allegations of revenue recognition fraud. The SEC’s complaint alleged that the audit committee had not met in person with the external auditor for two consecutive fiscal years, a violation of the committee’s own charter. For Hong Kong-based INEDs serving on U.S.-listed boards, this creates a direct personal liability risk that is not mitigated by the issuer’s D&O insurance, as the SEC’s claims are typically excluded from standard policies unless specifically endorsed.

The Role of the Audit Committee Charter

The SEC requires that each audit committee have a written charter that specifies its responsibilities, including the oversight of the external auditor, the review of financial statements, and the establishment of procedures for whistleblower complaints. For PRC issuers, the charter must also address the unique risks of the VIE structure, including the auditor’s access to PRC operating company records and the committee’s oversight of the VIE agreements. The SEC’s 2025 guidance recommends that the charter explicitly state that the committee has the authority to engage independent legal counsel and accounting advisors at the issuer’s expense, a provision that is often absent in HKEX-compliant charters. The HKEX’s Listing Rule 3.22 requires that the audit committee have sufficient resources to perform its duties, but it does not mandate the specific language on independent advisor engagement. For dual-listed issuers, the U.S. charter must be the governing document for committee operations, and the HKEX committee may need to adopt a separate charter that aligns with the U.S. version.

Actionable Takeaways

1. Audit committee composition for dual-listed PRC issuers must be assessed under the SEC’s Rule 10A-3 independence test, which is stricter than the HKEX’s Rule 3.13, and any director with a commercial or professional services relationship to the VIE operating company is disqualified from U.S. audit committee membership.

2. The audit committee financial expert must be a U.S. CPA or equivalent with demonstrated U.S. GAAP experience, and the issuer must ensure a cooling-off period of at least three years from any prior employment with the external auditor to avoid SEC enforcement action.

3. The audit committee charter for U.S.-listed issuers must explicitly authorise the committee to engage independent legal counsel and accounting advisors at the issuer’s expense, a provision that is not required by the HKEX but is essential for compliance with SEC expectations.

4. Personal liability for audit committee members under Section 10A of the Exchange Act is a real and escalating risk, and Hong Kong-based INEDs should require the issuer to provide specific D&O coverage for SEC claims, including a separate limit for securities law liabilities.

5. For issuers using a Cayman Islands holding company, the board must pass resolutions specifically appointing committee members under U.S. rules and ensuring that the Cayman constitutional documents do not conflict with the SEC’s independence requirements, particularly regarding the definition of “affiliated person.”
