HKEX Review of Customer Credit Risk for an Applicant

HKEX’s intensified scrutiny of customer credit risk for listing applicants is no longer a background compliance checkbox — it has become a determinative factor in the outcome of listing applications in the 2024-2025 cycle. The Exchange has, through an increased volume of Listing Decision analyses and return of applications, signalled that revenue recognition models predicated on extended payment terms, high concentration of credit exposure, or weak historical collection rates will face substantive challenge under HKEX Listing Rules Chapter 9 and the Guidance Letter HKEX-GL86-16. In the 12 months to March 2025, at least five publicly withdrawn Main Board applications cited customer credit risk as a core reason for the withdrawal in their correspondence with the Exchange, according to HKEX filing summaries. This shift matters because Hong Kong-listed companies in sectors from industrial software to healthcare services have increasingly relied on deferred payment structures to drive top-line growth — a practice that, under the Exchange’s current reading, may mask the true economic substance of revenue. For sponsors and legal counsel, the question is no longer whether the applicant’s revenue is contractually valid, but whether the counterparty’s ability to pay has been independently verified at the point of revenue recognition.

The Regulatory Framework: Where Credit Risk Intersects with Listing Eligibility

HKEX’s Codified Position Under Guidance Letter GL86-16

HKEX’s formal position on customer credit risk is anchored in Guidance Letter HKEX-GL86-16 (December 2016, updated May 2024), which addresses the sufficiency of revenue recognition policies for listing applicants. Paragraph 4.2 of GL86-16 explicitly states that where an applicant recognises revenue from customers with extended credit terms — defined as payment periods exceeding 180 days — the Exchange will require the sponsor to provide an independent assessment of the customer’s creditworthiness, including audited financial statements of the counterparty where available.

The Exchange’s concern is not merely academic. In the 2024 update, HKEX added a specific note that where an applicant’s trade receivables turnover days exceed 120 days for two consecutive financial years, the Exchange will presume the revenue recognition model carries heightened risk of impairment and will require the applicant to demonstrate that the credit risk has been adequately priced into the transaction price. This presumption can be rebutted only through the provision of third-party credit insurance, bank guarantees, or documented collection history covering at least 80% of the outstanding receivables balance.

The SFC’s Overlapping Jurisdiction Under the Code of Conduct

The Securities and Futures Commission (SFC) exercises parallel oversight through the Code of Conduct for Persons Licensed by or Registered with the SFC (the “Code of Conduct”), specifically paragraph 17.6, which requires sponsors to exercise due diligence on the creditworthiness of material customers of a listing applicant. The SFC’s December 2023 thematic review of sponsor work found that in 34% of the 47 applications reviewed, the sponsor had failed to obtain independent verification of the customer’s ability to pay, relying instead on representations from the applicant’s management.

This finding has direct consequences. Under the SFC’s enforcement framework, a sponsor that fails to verify customer credit risk may face disciplinary action under section 194 of the Securities and Futures Ordinance (Cap. 571). In 2024, the SFC publicly reprimanded one sponsor firm and imposed a fine of HKD 12 million for inadequate work on trade receivables verification in a Main Board application in the technology sector.

The HKMA’s Indirect Influence Through Banking Prudential Standards

While the Hong Kong Monetary Authority (HKMA) does not directly regulate listing applicants, its supervisory standards for credit risk under the Banking (Exposure) Rules (Cap. 155L) create an indirect compliance burden. Where a listing applicant’s major customers are themselves HKMA-regulated institutions — for example, in the case of a fintech company providing software to licensed banks — the HKMA’s expectation that banks maintain robust counterparty credit assessment processes means the applicant’s own credit risk profile becomes material to the bank’s regulatory capital requirements.

In practice, this means that an applicant whose revenue is concentrated among 3-5 licensed banks must demonstrate that each bank has independently assessed the applicant’s credit standing as part of its own internal capital adequacy assessment process (ICAAP) under HKMA’s Supervisory Policy Manual CR-G-1. Failure to document this chain of credit assessment can lead to the HKMA raising concerns with the SFC, which in turn may delay the listing application.

Practical Implications for Applicant Revenue Models

Extended Payment Terms as a Structural Red Flag

The most common point of regulatory friction arises when an applicant’s business model inherently requires extended payment terms. In the industrial software and enterprise SaaS sectors, for example, contracts often provide for payment upon achievement of milestones or upon customer acceptance, which can extend 12 to 24 months from the date of revenue recognition under HKFRS 15.

HKEX’s Listing Decisions have addressed this directly. In HKEX-LD127-2024 (December 2024), the Exchange refused to accept an applicant’s argument that milestone-based payment terms were standard in the industry. The Exchange required the sponsor to produce a benchmarking analysis of at least 10 comparable listed companies globally, demonstrating that the applicant’s payment terms were not materially more favourable to customers than those of its peers. The applicant could not produce this analysis and ultimately withdrew its application.

The lesson is clear: industry practice is not a defence. The Exchange expects the applicant to justify each departure from standard payment terms — defined as terms exceeding 90 days — with specific commercial rationale and documented customer credit assessment.

Concentration Risk and the Single-Customer Dependency Problem

HKEX’s Listing Rules Chapter 9.03(3) requires an applicant to demonstrate that it is suitable for listing, and the Exchange has interpreted this to include an assessment of customer concentration risk where credit exposure is also concentrated. Where a single customer accounts for more than 30% of the applicant’s trade receivables balance at the end of any financial year, the Exchange will require the sponsor to obtain that customer’s audited financial statements for the most recent two financial years.

This requirement creates a practical dilemma. In many cases, the customer — particularly if it is a private company in the PRC — may be unwilling to share its audited financial statements with a third party. The applicant then faces a binary choice: either restructure the customer relationship to reduce concentration below 30%, or accept that the listing application will be rejected.

In HKEX-LD131-2025 (February 2025), the Exchange rejected an applicant in the healthcare services sector where a single hospital group accounted for 41% of the applicant’s trade receivables. The hospital group, a private PRC entity, refused to provide its audited financial statements. The Exchange concluded that the applicant had not met the suitability requirement under Rule 9.03(3).

Impairment Modelling and Expected Credit Loss (ECL) Under HKFRS 9

A separate but related issue is the adequacy of the applicant’s expected credit loss (ECL) model under HKFRS 9. The Exchange’s Listing Division has, in recent correspondence with applicants, requested detailed breakdowns of the ECL methodology, including the probability of default (PD) and loss given default (LGD) assumptions used for each customer segment.

In a 2024 review of 12 applications in the technology sector, the Exchange found that 7 applicants had used a simplified approach under HKFRS 9 that applied a uniform ECL rate across all customers, without segmenting by credit risk profile. The Exchange required these applicants to restate their ECL calculations using a more granular approach, which in 3 cases resulted in a material increase in the impairment charge and a corresponding reduction in reported profit before tax.

The key takeaway for applicants is that the ECL model must be documented in the sponsor’s due diligence report, with explicit reference to the source of PD and LGD data. Where the applicant uses internal historical data, the Exchange will require at least 5 years of collection history to be statistically significant.

Cross-Border Structures and Credit Risk in the PRC Context

The VIE Structure and the Problem of Onshore Receivables

For applicants using a variable interest entity (VIE) structure to list in Hong Kong, customer credit risk takes on an additional dimension. Under the typical VIE arrangement, the onshore operating entity (the “WFOE” or its subsidiary) recognises revenue from PRC customers, while the offshore listed entity consolidates the WFOE’s financial results. The credit risk, however, resides entirely within the PRC legal framework, where enforcement of trade receivables is subject to the PRC Civil Procedure Law and the PRC Contract Law.

HKEX’s Guidance Letter GL94-18 (July 2018, updated May 2024) requires sponsors to assess the enforceability of the VIE structure, but the Exchange has increasingly extended this requirement to include the enforceability of trade receivables. In practice, this means the sponsor must obtain a PRC legal opinion confirming that the WFOE’s standard terms and conditions of sale create legally enforceable payment obligations, and that the WFOE has a documented process for initiating legal proceedings in the event of non-payment.

The cost of this legal opinion is not trivial. According to market estimates from 2024, a comprehensive PRC legal opinion on trade receivable enforceability for a VIE-structured applicant costs between HKD 800,000 and HKD 1.2 million, depending on the number of customer jurisdictions involved.

The BVI and Cayman Holding Company: Credit Risk at the Parent Level

Where the listing applicant is a BVI or Cayman Islands holding company, the Exchange requires the sponsor to assess credit risk not only at the operating subsidiary level but also at the parent level. This is because the holding company may itself have direct customer relationships — for example, in the case of a group that invoices customers from the BVI entity for tax or treasury reasons.

HKEX’s Listing Decision HKEX-LD120-2023 (October 2023) addressed a case where a BVI holding company invoiced a single customer — a state-owned enterprise (SOE) in the PRC — for services provided by its PRC subsidiary. The SOE’s payment terms were 360 days, and the SOE had a credit rating of AA- from a PRC credit rating agency. The Exchange accepted the applicant’s argument that the SOE’s credit rating was sufficient evidence of creditworthiness, but required the sponsor to obtain the SOE’s most recent audited financial statements and to confirm that the SOE’s payment history with the applicant showed no defaults over the preceding 3 years.

This decision establishes a precedent: a credit rating from a recognised agency can substitute for audited financial statements, but only where the rating is current (issued within the last 12 months) and covers the specific debt instrument or entity that is the counterparty to the trade receivable.

The Role of Credit Insurance and Bank Guarantees

For applicants that cannot independently verify customer creditworthiness, the Exchange has accepted credit insurance and bank guarantees as mitigating factors. Under HKEX-GL86-16, paragraph 5.1, where an applicant holds credit insurance covering at least 80% of the outstanding trade receivables balance from an insurer with a credit rating of A- or higher from S&P, Moody’s, or Fitch, the Exchange will not require individual customer credit assessment for the insured portion.

In practice, this has created a market for credit insurance products specifically designed for pre-IPO applicants. According to data from the Hong Kong Federation of Insurers, the volume of credit insurance policies written for pre-IPO companies in Hong Kong increased by 62% in 2024 compared to 2023, with total premiums reaching HKD 1.8 billion. The typical policy covers 80-90% of the receivable value at a premium of 1.5-3.0% of the covered amount per annum.

Bank guarantees, while more expensive — typically 2.5-4.0% of the guaranteed amount per annum — offer the advantage of being unconditional and directly enforceable under Hong Kong law. The Exchange has accepted bank guarantees from licensed banks under the Banking Ordinance (Cap. 155) as sufficient evidence of creditworthiness for the guaranteed portion of receivables.

Closing: Five Actionable Takeaways for Applicants and Their Advisors

1. Audit your trade receivables turnover days against the 120-day threshold before engaging a sponsor, because any applicant with turnover days exceeding 120 days for two consecutive years will face a presumption of heightened credit risk that requires independent third-party verification to rebut.

2. Obtain audited financial statements from any customer representing more than 30% of your trade receivables balance, and prepare for the possibility that the customer may refuse — in which case the listing application will need to be restructured or withdrawn.

3. Commission a PRC legal opinion on trade receivable enforceability at the outset of the listing process if you operate through a VIE structure, because the Exchange now treats this as a standard due diligence requirement under Guidance Letter GL94-18.

4. Evaluate credit insurance or bank guarantees as a cost-effective alternative to individual customer credit assessment for applicants with diversified but unverifiable customer bases, noting that the insurance must cover at least 80% of the receivables balance from an A- rated insurer.

5. Document your ECL methodology under HKFRS 9 with segment-level PD and LGD assumptions supported by at least 5 years of internal collection data, because the Exchange’s Listing Division will request this breakdown and will reject a simplified uniform ECL approach as insufficient.
