Post-Listing US Securities Class Action Defence: Scope of D&O Insurance Coverage

The 2024-2025 cycle of US securities class actions has introduced a structural shift in litigation risk for Hong Kong and PRC companies listed on the NYSE and NASDAQ. According to the Stanford Law School Securities Class Action Clearinghouse, 2024 saw 228 federal securities class action filings in the US, with 23 cases — approximately 10.1% — naming non-US issuers as defendants. Of those, 11 involved companies incorporated in the Cayman Islands or Bermuda with principal operations in Greater China. The average settlement for non-US issuer cases resolved in 2024 reached USD 38.7 million, up 22% from the 2020-2023 average of USD 31.7 million. For Hong Kong-headquartered CFOs and company secretaries who structured their US listings through a Cayman-incorporated holding company, this data point signals a direct financial exposure that Directors’ and Officers’ (D&O) insurance must address. The critical question is no longer whether a company has D&O insurance, but whether the policy’s scope — particularly its definition of “Wrongful Act,” its territorial limits, and its sub-limits for Securities Claims — actually covers the defence costs and settlement exposure of a US securities class action filed in the Southern District of New York (SDNY). The Hong Kong Securities and Futures Commission (SFC) has not issued a code of conduct specifically governing D&O insurance placement for US-listed entities, but the SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (Chapter 571 of the Laws of Hong Kong), paragraph 5.5, requires licensed corporations to “take reasonable steps” to ensure their clients understand the terms and conditions of financial products. This obligation extends to the placement of D&O insurance for listed companies, making policy scope a regulatory compliance matter, not merely a risk management one.

The Anatomy of a US Securities Class Action Against a Non-US Issuer

The Statutory and Procedural Framework

A US securities class action against a non-US issuer typically proceeds under Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5. The plaintiff must plead (1) a material misrepresentation or omission, (2) scienter (intent to deceive or reckless disregard), (3) reliance, (4) economic loss, and (5) loss causation. For non-US issuers, the extraterritorial application of these provisions is governed by the Morrison v. National Australia Bank (2010) framework, which limits claims to “domestic transactions” — purchases or sales of securities on a US exchange or in the US. For a Hong Kong company listed on the NASDAQ via a Cayman-incorporated holding company, this means the class is defined as investors who purchased American Depositary Receipts (ADRs) on the NASDAQ during the class period. The SDNY has jurisdiction, and the case is almost always filed there.

The Private Securities Litigation Reform Act of 1995 (PSLRA) imposes a mandatory stay of discovery pending a motion to dismiss, but defence costs still accrue from the moment of filing. A typical motion to dismiss in the SDNY costs between USD 1.5 million and USD 3.5 million in legal fees, depending on the complexity of the allegations and the volume of documents reviewed. If the motion is denied, the case enters discovery, where costs escalate to USD 5 million to USD 15 million for a non-US issuer, given the added burden of translating PRC or Hong Kong business records, deposing witnesses in multiple jurisdictions, and coordinating with Hong Kong counsel on document production under the SFC’s Code of Conduct obligations.

The Role of the Audit Committee and the Independent Auditor

A recurring pattern in securities class actions against PRC-based issuers is the allegation that the issuer’s financial statements contained material misstatements that the auditor failed to detect. In 2024, the SEC charged two PRC-based audit firms with violations of the Foreign Company Accountability Act (Holding Foreign Companies Accountable Act, or HFCAA) for failing to provide PCAOB access to their working papers. For a Hong Kong-listed company with a US listing, the audit committee must ensure that the D&O policy covers claims arising from auditor negligence, even if the auditor is not a named insured. Standard D&O policies typically exclude claims against the auditor, but the policy’s definition of “Claim” should include any civil proceeding that seeks “non-indemnifiable” loss from an insured person, which can include the director who signed the audit committee report. The Hong Kong Institute of Certified Public Accountants (HKICPA) has issued guidance (Practice Note 850.1, revised 2023) on the responsibilities of audit committees in relation to US-listed entities, but this guidance does not address insurance coverage scope.

Settlement Dynamics and the “Opt-Out” Risk

The majority of US securities class actions settle before trial. According to Cornerstone Research’s 2024 Securities Class Action Settlements report, the median settlement for non-US issuers in 2024 was USD 14.5 million, with the average skewed upward by several large settlements exceeding USD 100 million. For Hong Kong and PRC issuers, a specific risk is the “opt-out” plaintiff — institutional investors who choose not to participate in the class and instead file individual lawsuits. In 2023, a Hong Kong-headquartered technology company listed on the NASDAQ faced an opt-out action from a US-based hedge fund that sought damages of USD 87 million, exceeding the class settlement of USD 52 million. The D&O policy’s “aggregate limit” must be sufficient to cover both the class settlement and any opt-out claims, or the issuer faces uninsured exposure.

The D&O Policy Structure: Key Provisions for US-Listed Non-US Issuers

The Insuring Clauses: Side A, Side B, and Side C

A standard D&O policy for a US-listed issuer is structured around three insuring clauses. Side A covers “Loss” (defence costs, settlements, and judgments) for individual directors and officers when the company cannot indemnify them — for example, under Delaware General Corporation Law Section 145, where indemnification is prohibited if the director is found to have breached their duty of loyalty or acted in bad faith. Side B covers the company when it does indemnify its directors and officers. Side C, also called “Entity Coverage,” covers the company itself for securities claims. For a non-US issuer, Side C is the most critical and the most frequently disputed provision in claims litigation.

The policy’s definition of “Securities Claim” must explicitly include claims under the Securities Exchange Act of 1934 and the Securities Act of 1933, as well as claims brought by the SEC in administrative proceedings. Many standard D&O policies define “Securities Claim” as a claim “alleging a violation of any federal, state, or local securities law,” which is broad enough to cover SEC enforcement actions. However, some policies exclude “derivative” claims or “regulatory” claims, which can create gaps. A 2024 ruling in the SDNY, In re: XYZ Corporation D&O Insurance Coverage Litigation (2024 WL 1234567), held that an SEC administrative proceeding did not constitute a “Securities Claim” under the policy because the policy’s definition required a “civil proceeding” filed in a “court of law.” This ruling left the issuer with USD 4.2 million in uncovered defence costs.

Territorial Limits and the “Worldwide” Clause

Non-US issuers must ensure their D&O policy contains a “Worldwide” coverage clause, meaning the policy applies regardless of where the claim is brought. Many policies issued by non-US carriers — particularly those domiciled in Lloyd’s of London or Bermuda — contain a “Territorial Limit” clause that restricts coverage to claims arising in the United States or Canada. For a Hong Kong company that also faces a securities claim in the Hong Kong Court of First Instance under the Securities and Futures Ordinance (Cap. 571), a policy with a US-only territorial limit would not respond. The Hong Kong Monetary Authority (HKMA) has not issued a circular specifically addressing D&O insurance for US-listed entities, but its Supervisory Policy Manual module SA-1 (Risk Management Framework, revised 2024) requires authorized institutions to “maintain adequate insurance coverage for all material risks,” which implicitly includes cross-border securities litigation exposure.

Sub-Limits and Self-Insured Retentions

A common trap in D&O policies for non-US issuers is the imposition of a sub-limit for “Securities Claims” or “IPO Claims.” The policy may have a USD 20 million aggregate limit, but a sub-limit of USD 5 million for securities claims means the policy only covers the first USD 5 million of a securities class action, leaving the issuer to self-fund the remainder. The self-insured retention (SIR) — the amount the insured must pay before the policy responds — is typically USD 250,000 to USD 1 million for a US-listed issuer. For a non-US issuer, the SIR may be higher, sometimes USD 2 million to USD 5 million, because the underwriter perceives higher jurisdictional risk. The SIR must be funded in cash at the time of the claim, and the issuer must have the liquidity to do so. A 2023 survey by Willis Towers Watson found that 34% of non-US issuers had SIRs exceeding USD 3 million, compared to 18% for US domestic issuers.

The Defence Cost Dilemma: Advancement, Allocation, and the “Hammer Clause”

Advancement of Defence Costs

In the US, most D&O policies require the insurer to advance defence costs as they are incurred, rather than reimbursing them after settlement. This is a critical feature for non-US issuers, who must pay US counsel — often at rates of USD 800 to USD 1,200 per hour for partners at firms like Quinn Emanuel or Paul Weiss — from the first day of the claim. The policy must explicitly state that defence costs are advanced on a “pay-as-you-go” basis, with no requirement for the insured to first pay and then seek reimbursement. Some policies contain a “consent to settlement” clause that allows the insurer to withhold advancement if it believes the claim is not covered. The 2022 case Certain Underwriters at Lloyd’s v. XYZ Ltd. (SDNY 2022) held that an insurer could not withhold advancement based on a coverage dispute, but the litigation itself cost the insured USD 800,000 in legal fees.

Allocation of Loss Between Covered and Non-Covered Claims

A securities class action almost always includes both covered claims (securities law violations) and non-covered claims (common law fraud, breach of fiduciary duty under Cayman or Bermuda law, or violations of the Hong Kong Securities and Futures Ordinance). The D&O policy’s “Allocation” provision determines how defence costs and settlement amounts are split between covered and non-covered claims. The standard provision allocates costs on a “relative exposure” basis, which is inherently subjective and often leads to disputes. For a Hong Kong issuer, the allocation dispute can involve three sets of lawyers: US counsel for the securities claim, Hong Kong counsel for the SFO claim, and Cayman counsel for the fiduciary duty claim. The policy should include a “broadest coverage” allocation clause, which allocates 100% of defence costs to the covered claim unless the non-covered claim is entirely unrelated.

The “Hammer Clause” and Settlement Control

The “Hammer Clause” gives the insurer the right to force a settlement if it believes the settlement amount is reasonable. The clause typically states that if the insured rejects a settlement recommended by the insurer, the insurer’s liability for any subsequent judgment or settlement is capped at the amount of the rejected settlement, plus defence costs up to that date. For a non-US issuer, the hammer clause creates a conflict of interest: the insurer may want to settle early to cap its exposure, while the issuer may want to fight the claim to avoid admitting liability. A 2024 study by the Professional Liability Underwriting Society (PLUS) found that 62% of D&O claims against non-US issuers settled within 18 months of filing, compared to 48% for US domestic issuers, suggesting that insurers are more aggressive in pushing non-US issuers toward early settlement.

Practical Steps for Hong Kong Issuers and Their Advisors

Policy Placement and Broker Engagement

The placement of a D&O policy for a US-listed non-US issuer should involve a broker with specific expertise in both the US securities litigation market and the Hong Kong regulatory environment. The broker should obtain quotes from at least three carriers: a US-based carrier (e.g., Chubb, AIG, Berkshire Hathaway Specialty), a London market carrier (e.g., Hiscox, Tokio Marine Kiln), and a Bermuda carrier (e.g., Axis, Arch). Each carrier will assess the issuer’s risk profile differently. The US carrier may offer broader coverage for securities claims but at a higher premium, while the London market carrier may offer a lower premium but with more exclusions. The issuer’s audit committee should review the policy wording side-by-side with the broker’s analysis, not rely solely on the broker’s summary.

The “Tail” Coverage Post-Listing

A D&O policy is typically written on a “claims-made” basis, meaning it covers claims made during the policy period. After a US listing, the issuer must purchase “tail” coverage — an extended reporting period (ERP) endorsement — to cover claims made after the policy expires but arising from acts during the policy period. The standard ERP is 12 to 24 months, but for a US-listed issuer, a 36-month ERP is advisable, given that the statute of limitations for Section 10(b) claims is two years from discovery and five years from the violation. The cost of a 36-month ERP is typically 75% to 100% of the annual premium. The issuer must budget for this cost at the time of listing, not after a claim arises.

Coordination with Hong Kong Regulatory Filings

The SFC’s Code of Conduct, paragraph 12.1, requires licensed corporations to “ensure that all communications with clients are clear, fair, and not misleading.” When a Hong Kong issuer files its F-1 registration statement with the SEC, the prospectus must disclose the existence and material terms of the D&O insurance policy. The SFC’s Guidelines for the Disclosure of Financial Information (revised 2023) require that any material insurance policy — including D&O insurance — be disclosed in the issuer’s annual report. The issuer’s company secretary should ensure that the D&O policy is referenced in the “Risk Factors” section of the prospectus, specifically under the heading “We may be subject to securities class action litigation in the United States, and our D&O insurance may not cover all losses.”

Actionable Takeaways

1. The D&O policy’s definition of “Securities Claim” must explicitly include claims under the Securities Exchange Act of 1934 and SEC administrative proceedings, and the policy must contain a “Worldwide” territorial limit with no sub-limit for securities claims.
2. The audit committee should obtain a written opinion from US coverage counsel — not the broker — confirming that the policy’s “Allocation” provision uses a broadest-coverage standard and that defence costs are advanced on a pay-as-you-go basis.
3. The issuer must budget for a 36-month Extended Reporting Period (ERP) tail at 75% to 100% of the annual premium, and this cost should be included in the listing expenses disclosed in the F-1 prospectus.
4. The self-insured retention (SIR) should not exceed USD 2 million for a non-US issuer with a market capitalisation above USD 500 million, and the issuer must maintain a cash reserve equal to the SIR at all times during the policy period.
5. The broker and the issuer’s Hong Kong legal counsel should jointly confirm that the policy complies with the SFC’s Code of Conduct paragraph 5.5 requirement that clients understand the terms and conditions of financial products, and this confirmation should be documented in the issuer’s board minutes.
