A Sponsor's Review of the Useful Life and Amortisation of the Listing Applicant's Intangible Assets

The SFC’s thematic inspection findings on sponsor due diligence, published in its December 2024 circular on sponsor compliance, identified intangible asset valuation as a recurrent area of deficiency in listing applications. The regulator noted that sponsors frequently accepted management’s assumptions on useful life and amortisation without independent challenge, particularly for technology-related intangibles acquired through business combinations. This regulatory scrutiny coincides with a broader shift in Hong Kong’s listing pipeline: as of Q1 2025, approximately 38% of applications pending before the HKEX involve applicants with material intangible asset balances exceeding 30% of total assets, according to HKEX data. The convergence of SFC enforcement priorities and market composition means that a sponsor’s review of useful life and amortisation is no longer a mechanical accounting exercise but a core due diligence obligation under the Listing Rules and the SFC’s Code of Conduct. Getting the analysis wrong exposes the sponsor to enforcement action under section 213 of the SFO and potential civil liability under the prospectus regime. This article sets out the regulatory framework, the sponsor’s procedural obligations, and the practical steps for challenging management’s assumptions on useful life and amortisation.

The Regulatory Framework for Intangible Asset Review

The sponsor’s duty to review useful life and amortisation arises from two overlapping regulatory regimes: the HKEX Listing Rules and the SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (the Code of Conduct). The Listing Rules require the sponsor to form a reasonable opinion that the listing applicant’s financial information is not misleading in any material respect, which necessarily encompasses the carrying value and amortisation of intangible assets. The Code of Conduct, particularly paragraph 17.6, imposes a higher standard: the sponsor must exercise due diligence to ensure that all material facts have been identified and properly disclosed in the prospectus.

The SFC’s Position on Useful Life Assessment

The SFC’s December 2024 circular on sponsor compliance explicitly states that sponsors must critically assess the useful life assigned to each class of intangible asset, including goodwill, customer relationships, technology, and brand names. The regulator observed that in several reviewed cases, sponsors accepted a 10-year useful life for technology-based intangible assets without analysing the underlying product lifecycle, the pace of technological obsolescence, or the applicant’s historical experience with similar assets. The SFC’s position is that a standardised useful life across all intangible assets, without asset-specific justification, is prima facie inadequate.

The circular cites an example where a listing applicant in the software-as-a-service sector assigned a 15-year useful life to its internally developed platform technology, relying on management’s assertion that the platform had been in commercial use for eight years without material modification. The SFC found that the sponsor had not obtained independent market data on the average useful life of comparable platforms, nor had it stress-tested the assumption against the applicant’s own product roadmap, which indicated a planned major version upgrade within 36 months. The regulator concluded that the sponsor’s due diligence was insufficient and referred the matter to the Enforcement Division.

The HKEX’s Guidance on Amortisation Methods

The HKEX’s Listing Decision LD143-2023 provides additional guidance on amortisation methods for intangible assets acquired in a business combination. The decision involved an applicant that amortised its customer relationship intangible assets using a straight-line method over 8 years, while the underlying customer contracts had a weighted average remaining term of 3.2 years. The Exchange rejected the amortisation method as inconsistent with the pattern of economic benefits expected to be derived from the asset, citing HKAS 38 paragraph 97, which requires the amortisation method to reflect the pattern in which the asset’s future economic benefits are expected to be consumed. The Exchange required the applicant to adopt an accelerated amortisation method that better matched the customer attrition pattern evidenced by historical data.

This decision establishes a clear precedent: the sponsor must not only verify the useful life but also the amortisation method. A straight-line method is not automatically acceptable, particularly for intangible assets where the economic benefits are front-loaded or where the asset has a finite pattern of consumption that is not linear.

The Sponsor’s Procedural Obligations in the Review Process

The sponsor’s review of useful life and amortisation is not a one-off exercise performed at the time of the listing application. It is an iterative process that spans the entire due diligence period, from the initial engagement through to the prospectus issuance. The SFC expects the sponsor to document its review in a manner that demonstrates independent challenge, not mere acceptance of management’s representations.

Independent Verification of Assumptions

The sponsor must independently verify the key assumptions underlying the useful life determination. This requires the sponsor to obtain and analyse primary data, not just management’s internal projections. For technology-related intangible assets, the sponsor should obtain third-party market reports on technology obsolescence rates, product lifecycle data from industry associations, and, where available, comparable company disclosures on useful lives. The SFC’s December 2024 circular specifically requires the sponsor to document the source of each assumption and to explain why that source is reliable and relevant.

For customer relationship intangible assets, the sponsor should analyse the applicant’s historical customer attrition data over at least a 5-year period, if available, and compare it to industry benchmarks. The sponsor should also review the terms of the underlying customer contracts, including any renewal options, termination clauses, and volume commitments. The HKEX’s LD143-2023 decision makes clear that the contractual term is not determinative of the useful life; the sponsor must assess the expected economic life based on the pattern of customer retention and repeat business.

Sensitivity Analysis and Stress Testing

The sponsor must perform sensitivity analysis on the key assumptions affecting useful life and amortisation. This is not a financial modelling exercise for impairment testing under HKAS 36, but a due diligence procedure to identify the range of reasonably possible outcomes. The sponsor should test the impact of a 20% reduction in useful life (a threshold commonly used in SFC enforcement cases) on the carrying value of the intangible assets and the applicant’s reported profit or loss. If the sensitivity analysis reveals that a reasonably possible change in useful life would result in a material misstatement of the financial statements, the sponsor must require the applicant to disclose that sensitivity in the prospectus.

The SFC’s enforcement track record supports this approach. In the SFC’s disciplinary action against Sponsor A in 2022 (Case No. SFC/DR/2022/03), the regulator found that the sponsor failed to perform any sensitivity analysis on the useful life assumption for a trademark intangible asset, which was subsequently written off within 18 months of listing. The sponsor was fined HKD 12 million and suspended from advising on corporate finance transactions for 12 months.

Documentation and Audit Trail

The sponsor must maintain a complete and contemporaneous documentation of its review of useful life and amortisation. The documentation should include: (i) the initial management assumptions and the basis for those assumptions; (ii) the sponsor’s independent analysis and the sources of data used; (iii) the results of sensitivity analysis and stress testing; (iv) any disagreements with management and how they were resolved; and (v) the final conclusions reached and the rationale for those conclusions. The SFC’s December 2024 circular emphasises that documentation must be created at the time the work is performed, not reconstructed after the fact.

Practical Challenges in Specific Asset Classes

The sponsor’s review of useful life and amortisation presents distinct challenges depending on the nature of the intangible asset. The most common categories encountered in listing applications are technology-related assets, customer relationships, and brand names. Each requires a tailored approach.

Technology-Related Intangible Assets

Technology-related intangible assets, including software, platform technology, and patents, are the most frequently scrutinised by the SFC. The sponsor must assess the technological obsolescence risk, which varies significantly by industry. For software-as-a-service applicants, the average useful life of platform technology in comparable listed companies is between 3 and 7 years, according to a 2024 study by the Hong Kong Institute of Certified Public Accountants (HKICPA). The sponsor should obtain the applicant’s product roadmap and assess whether planned upgrades or new versions will replace or significantly modify the existing technology. If the applicant plans a major version upgrade within 3 years, a useful life exceeding 5 years would require strong justification.

The sponsor should also consider the legal protection afforded by patents or copyrights. A patent with a remaining legal life of 12 years does not automatically justify a 12-year useful life if the underlying technology is expected to become obsolete within 5 years. The HKEX’s guidance in LD143-2023 is clear: the economic useful life is the shorter of the legal life and the expected period over which the asset will generate economic benefits.

Customer Relationship Intangible Assets

Customer relationship intangible assets are typically amortised over the expected period of customer retention. The sponsor must analyse the applicant’s historical customer attrition rate and compare it to industry benchmarks. If the applicant’s attrition rate is 15% per annum, the implied average customer life is approximately 6.7 years (1 / 0.15). The sponsor should test this against the contractual terms: if the average contract term is 3 years with annual renewal options, the useful life should reflect the expected renewal behaviour, not just the initial contract term.

The sponsor must also consider whether the customer relationship intangible asset includes non-contractual customer relationships. The HKEX’s LD143-2023 decision addressed this point: non-contractual customer relationships must be amortised over a period that reflects the expected duration of the relationship, which is typically shorter than contractual relationships due to the absence of a legal obligation to continue purchasing.

Brand Names and Trademarks

Brand names and trademarks present a unique challenge because they can have indefinite useful lives if the applicant intends to maintain the brand indefinitely and has the resources to do so. However, the SFC expects the sponsor to critically assess whether the brand has a finite useful life based on market trends, competitive dynamics, and the applicant’s business strategy. For example, a brand that is dependent on a single product or a specific technology may have a finite useful life if the product or technology is expected to become obsolete.

The sponsor should obtain independent brand valuation reports and compare the useful life assumptions to those used by comparable listed companies. The SFC’s December 2024 circular notes that in one reviewed case, the sponsor accepted a 20-year useful life for a brand name without analysing the applicant’s marketing expenditure trend, which had been declining for 3 consecutive years. The regulator concluded that a declining marketing budget was inconsistent with an intention to maintain the brand indefinitely and required the useful life to be reduced to 10 years.

The Intersection with Impairment Testing

The sponsor’s review of useful life and amortisation is closely linked to impairment testing under HKAS 36. The useful life assumption directly affects the carrying value of the intangible asset and, consequently, the recoverable amount calculation. If the useful life is overstated, the carrying value will be higher, and the risk of impairment is deferred. The sponsor must ensure that the useful life assumption used for amortisation is consistent with the assumptions used in the impairment testing model.

Consistency Between Amortisation and Impairment Assumptions

The sponsor should verify that the cash flow projections used in the impairment testing model reflect the same useful life as the amortisation schedule. If the impairment model assumes that the intangible asset will generate cash flows for 10 years, but the amortisation schedule uses a 15-year useful life, there is an inconsistency that must be resolved. The HKEX’s Listing Decision LD143-2023 requires the sponsor to reconcile these assumptions and to disclose any material differences in the prospectus.

Triggering Events for Useful Life Reassessment

The sponsor must also consider whether any triggering events have occurred that require a reassessment of the useful life. The SFC’s December 2024 circular identifies the following events as potential triggers: (i) a significant change in the applicant’s business model or product strategy; (ii) the emergence of a competing technology that could render the applicant’s technology obsolete; (iii) a material decline in customer retention rates; and (iv) a significant reduction in marketing expenditure for brand-related assets. The sponsor should document its assessment of whether any triggering events have occurred and, if so, the impact on the useful life assumption.

Actionable Takeaways for Sponsors

The following specific actions should be incorporated into the sponsor’s due diligence work programme for intangible asset review:

1. Obtain and maintain independent third-party data on useful life benchmarks for each class of intangible asset, sourced from industry reports, comparable company disclosures, or HKICPA guidance, and document the rationale for selecting each source.

2. Perform sensitivity analysis on the useful life assumption using a 20% reduction as the baseline scenario, and require the applicant to disclose the impact in the prospectus if the result would be material to the applicant’s financial position or results.

3. Verify the consistency between the useful life used for amortisation and the assumptions in the impairment testing model, and document any reconciliation performed.

4. Assess the amortisation method against the pattern of economic benefits expected to be derived from the asset, and reject a straight-line method without specific justification for each class of intangible asset.

5. Document all disagreements with management on useful life and amortisation assumptions, including the sponsor’s analysis, management’s response, and the final resolution, and retain this documentation in the sponsor’s working papers for a minimum of 7 years after the listing.
