What Is Related-Party Transaction Disclosure? Revealing Conflicts of Interest in an S-1

The SEC’s Division of Corporation Finance has, since early 2025, intensified its review of related-party transaction (RPT) disclosures in S-1 registration statements, particularly for issuers from jurisdictions with concentrated ownership structures, including Hong Kong and the PRC. This heightened scrutiny follows a series of post-IPO enforcement actions where undisclosed RPTs were linked to asset diversion and financial restatements, eroding investor confidence in newly listed companies. For CFOs and company secretaries preparing for a US listing, the S-1’s Item 404 of Regulation S-K now functions as a de facto litmus test for corporate governance quality, with SEC staff routinely issuing comment letters demanding granular detail on transactions with directors, officers, and their affiliates. The stakes are material: a 2024 study by the Investor Responsibility Research Center Institute found that companies with incomplete RPT disclosures in their S-1s experienced an average 12.3% underperformance in their first six months of trading relative to peers with full compliance. This article dissects the regulatory architecture, the specific disclosure mechanics, and the practical filing strategies that separate a clean SEC review from a protracted comment letter cycle.

The Regulatory Framework Under Regulation S-K Item 404

Item 404 of Regulation S-K mandates disclosure of any transaction since the beginning of the issuer’s last fiscal year, or any currently proposed transaction, in which the issuer was or is to be a participant and the amount involved exceeds USD 120,000, and in which any related person had or will have a direct or indirect material interest. The SEC’s 2022 amendments, effective for fiscal years ending on or after 15 August 2023, raised the threshold from USD 120,000 to the current level and expanded the definition of “related person” to include any director, executive officer, nominee for director, or shareholder holding more than 5% of the issuer’s voting equity.

The SEC’s definition under Item 404(a) covers a broader net than Hong Kong’s Listing Rules Chapter 14A, which focuses on connected transactions with substantial shareholders (10% or more) and directors. For US filings, a related person includes any immediate family member of the foregoing individuals—spouses, parents, children, siblings, and in-laws—regardless of whether they hold any formal position in the company. This expansive scope catches structures common in Hong Kong-incorporated issuers, where family trusts and nominee arrangements are prevalent. The SEC staff, in a 2024 Compliance and Disclosure Interpretation, clarified that a transaction between the issuer and a company controlled by a director’s sibling falls within Item 404’s ambit, even if the sibling holds no ownership in the issuer.

The USD 120,000 Materiality Threshold

The USD 120,000 threshold is absolute, not relative to the issuer’s revenue or market capitalisation. A Hong Kong-based biotech issuer with HKD 50 million in annual revenue must disclose every RPT exceeding approximately HKD 936,000 at current exchange rates, regardless of whether the transaction is immaterial to the financial statements. This contrasts with the HKEX’s de minimis exemption under Rule 14A.76, which exempts connected transactions below 0.1% of the issuer’s market capitalisation or HKD 3 million. The SEC’s bright-line rule eliminates discretion; issuers cannot argue that a USD 130,000 consulting fee to a director’s spouse is too small to matter.

The Material Interest Test Beyond the Dollar Amount

Even if a transaction exceeds USD 120,000, disclosure is only required if the related person has a “direct or indirect material interest.” The SEC’s definition of materiality follows the standard set in Basic Inc. v. Levinson (1988): information is material if there is a substantial likelihood that a reasonable investor would consider it important in making an investment decision. In practice, SEC staff presume materiality for transactions with executive officers and directors. For transactions with 5% shareholders or family members, the issuer must affirmatively assess whether the interest is material. A 2023 SEC comment letter to a Cayman-incorporated Chinese e-commerce issuer demanded the company explain why a USD 2.1 million loan from a 6% shareholder’s affiliated entity was not deemed material, given the shareholder’s ability to influence the board.

Disclosure Mechanics in the S-1: Structure and Content

The RPT disclosure must appear in a separate section of the S-1, typically under “Certain Relationships and Related Party Transactions,” or be incorporated by reference from the proxy statement if the issuer is a well-known seasoned issuer (WKSI). The SEC requires a narrative description, not merely a tabular listing, covering the nature of the relationship, the transaction’s purpose, the dollar amount, and the terms and conditions.

Identifying the Parties and Their Relationships

Each disclosed transaction must name the related person, describe their relationship to the issuer, and state the basis on which they are considered a related person. For a Hong Kong-incorporated issuer with a BVI holding company structure, the SEC expects the disclosure to trace the ultimate beneficial ownership. A 2024 S-1 for a PRC-based fintech issuer listed the following: “Mr. Chen Wei, a director and the brother of the CEO, is the sole shareholder of BVI-incorporated Golden Bridge Holdings Ltd., which provided IT consulting services to the issuer for USD 450,000 in fiscal 2024.” The SEC staff, in its comment letter, asked the issuer to confirm whether Mr. Chen’s spouse held any interest in the BVI entity, reflecting the expansive family member definition.

Describing the Transaction Terms and Business Purpose

The narrative must include the transaction’s principal terms, including the amount involved, the consideration paid or received, the duration, and any collateral or guarantees. The SEC also requires a statement of the business purpose—why the issuer entered into the transaction with the related person rather than an unaffiliated third party. For issuers with intercompany loans from their Hong Kong operating subsidiary to the Cayman parent, the disclosure must explain the interest rate, repayment schedule, and whether the loan was made on arm’s-length terms. A 2023 SEC comment letter to a Bermuda-incorporated shipping company requested a benchmarking analysis comparing the interest rate on a director’s loan (LIBOR + 200 bps) to rates available from commercial banks for similar unsecured credit.

Policies and Procedures for Review and Approval

Item 404(b) requires the issuer to describe its policies and procedures for the review, approval, or ratification of related-party transactions. The SEC expects a clear statement of which body—typically the audit committee or a separate conflicts committee—reviews such transactions, the threshold for committee review, and whether the policy covers transactions with family members and affiliates. For Hong Kong issuers, this section must reconcile with the HKEX’s connected transaction requirements under Chapter 14A, which mandate independent shareholder approval for certain transactions. A 2024 S-1 for a Hong Kong-listed company undertaking a US secondary listing included a cross-reference to its HKEX-compliant connected transaction policy but added a US-specific section confirming that all RPTs exceeding USD 120,000 are reviewed by the audit committee, regardless of HKEX exemptions.

Common Pitfalls in RPT Disclosure for Hong Kong and PRC Issuers

SEC staff comment letters on RPT disclosures for non-US issuers have clustered around three recurring issues: incomplete identification of related persons, failure to disclose indirect interests through layered entities, and inadequate explanation of business purpose for recurring transactions.

The Family Trust and Nominee Shareholding Problem

Hong Kong and PRC issuers frequently employ family trusts and nominee arrangements to hold equity, often through BVI or Cayman vehicles. The SEC’s view, articulated in a 2024 Staff Legal Bulletin, is that the settlor, trustee, and beneficiaries of a trust are all considered related persons if any one of them meets the Item 404 definition. A 2023 S-1 for a PRC education company disclosed a loan from a trust controlled by the founder’s father but failed to name the father as a related person. The SEC issued a deficiency letter requiring the issuer to amend the S-1 to identify the father and disclose his relationship to the founder. The issuer’s subsequent amendment added the father as a related person and disclosed that he was also a 3% indirect shareholder through the trust, triggering additional disclosure under Item 404(a)(2).

Recurring Transactions and Aggregate Disclosure

For issuers with ongoing business relationships with related parties—such as rental agreements, supply contracts, or shared services arrangements—the SEC requires disclosure of the aggregate amount for each category of transaction, not just the largest individual transaction. A 2024 comment letter to a Hong Kong-based manufacturing issuer demanded that the company disclose the total rental payments to a director’s property company over the past three fiscal years, rather than just the annual rent of HKD 2.8 million. The SEC staff noted that the aggregate of HKD 8.4 million over three years was material to the issuer’s net income of HKD 35 million, and the director’s interest in the property company was not disclosed in the initial filing.

The Business Purpose Justification Gap

The SEC’s most common deficiency in RPT disclosures is the lack of a substantive business purpose explanation. Issuers often state that the transaction was “on arm’s-length terms” without explaining why the issuer did not source the product or service from an unaffiliated third party. A 2025 SEC comment letter to a Cayman-incorporated semiconductor issuer requested a detailed explanation of why the company purchased raw materials from a supplier owned by the CEO’s cousin at a 15% premium to market prices, rather than from the issuer’s existing third-party suppliers. The issuer’s response, which cited “supply chain reliability and long-standing relationship,” was accepted only after the issuer provided a benchmarking analysis showing that the premium was justified by shorter delivery times and higher quality specifications.

Strategic Considerations for the S-1 Filing Process

The RPT disclosure section is a primary target for SEC comment letters, often generating two to three rounds of correspondence. For Hong Kong and PRC issuers, the preparation strategy should begin at least six months before the confidential S-1 submission, with a forensic audit of all transactions with directors, officers, and 5% shareholders.

The Pre-Filing Audit and Documentation Trail

The issuer’s sponsor and legal counsel should compile a complete inventory of all transactions exceeding USD 120,000 with any related person over the past three fiscal years. Each transaction should be documented with: (i) the contract or agreement; (ii) board or audit committee approval minutes; (iii) evidence of arm’s-length pricing, such as third-party quotes or benchmarking studies; and (iv) a written business purpose memorandum. For Hong Kong-incorporated issuers, the sponsor should reconcile this inventory against the connected transaction disclosures in the HKEX annual report, identifying any transactions that were exempt under HKEX rules but exceed the SEC’s USD 120,000 threshold.

Anticipating SEC Comment Letter Themes

Based on the SEC’s 2024 and 2025 comment letter trends, issuers should prepare responses for the following likely inquiries: (i) confirmation that all family members of directors and executive officers have been identified; (ii) explanation of why any transaction below USD 120,000 was excluded, particularly if the aggregate of similar transactions is material; (iii) details on how the issuer determined that a related person’s interest was not material; and (iv) a comparison of the issuer’s RPT policy with the SEC’s requirements under Item 404(b). For issuers with VIE structures, the SEC will also scrutinise transactions between the VIE and its PRC shareholders, which often fall outside the Hong Kong operating entity’s books.

The Materiality Waiver and Subsequent Amendments

If an issuer identifies a previously undisclosed RPT during the SEC review process, the appropriate response is a pre-effective amendment to the S-1, not a waiver request. The SEC does not grant materiality waivers for RPT disclosure; any omission is treated as a deficiency that must be cured before the registration statement can be declared effective. A 2024 case involving a Singapore-based logistics issuer saw the SEC delay effectiveness by four weeks after the issuer discovered a USD 1.8 million consulting contract with a director’s son that was omitted from the initial filing. The issuer filed a pre-effective amendment, disclosed the transaction, and revised its RPT policy to include a quarterly review requirement.

Actionable Takeaways for CFOs and Company Secretaries

Conduct a forensic audit of all transactions with directors, officers, 5% shareholders, and their immediate family members for the past three fiscal years, using the SEC’s USD 120,000 threshold as the sole materiality benchmark, regardless of HKEX exemptions.
Document every RPT with a written business purpose memorandum and arm’s-length pricing benchmarking analysis before the confidential S-1 submission, as SEC staff will request this evidence in comment letters.
Reconcile the US S-1 RPT disclosure with the HKEX annual report’s connected transaction section, identifying and explaining any transactions that are exempt under HKEX Rule 14A.76 but exceed the SEC’s threshold.
Prepare a pre-filing response template for the three most common SEC comment letter themes: incomplete family member identification, aggregate transaction disclosure, and business purpose justification.
Establish a quarterly RPT review process by the audit committee, with a written policy that explicitly covers transactions with family trusts, nominee shareholders, and BVI/Cayman intermediary entities.
