Disclosure Requirements for Goodwill and Intangible Asset Impairment Testing Pre-IPO

The Hong Kong Stock Exchange (HKEX) has intensified its scrutiny of goodwill and intangible asset impairment testing in pre-IPO applications, a direct response to a rising number of failed forecasts and post-listing earnings disappointments. In its 2025 Listing Decision (LD125-2025), the Exchange explicitly warned that issuers with significant goodwill or indefinite-life intangible assets must demonstrate the robustness of their impairment testing methodologies, or face rejection of their listing applications. This follows a broader global trend, with the International Accounting Standards Board (IASB) issuing its Business Combinations—Disclosure, Goodwill and Impairment amendments in 2024, effective for annual periods beginning on or after 1 January 2025. For Hong Kong-listed companies and applicants, the practical impact is immediate: the HKEX now expects cash-generating unit (CGU) allocation, discount rate justification, and terminal value assumptions to be auditable and stress-tested against a minimum of three distinct macroeconomic scenarios. The SFC’s 2024 enforcement report noted that 14 of 27 investigated cases involved material misstatements in asset valuations, with goodwill impairment errors accounting for HKD 2.8 billion in overstated profits. This article dissects the specific disclosure requirements, regulatory expectations, and practical compliance steps for pre-IPO companies preparing their listing documents.

The Regulatory Framework: HKEX Listing Rules and HKAS 36

Mandatory Disclosure in the Prospectus

Under HKEX Listing Rules Chapter 11 (for Main Board) and Chapter 20 (for GEM), a listing applicant must include a detailed discussion of its significant assets and liabilities, including intangible assets and goodwill. The Listing Rules do not prescribe a specific format, but the Guide on Listing Documents (2024 edition) explicitly requires that the “accounting policies and critical accounting estimates” section of the prospectus disclose the methodology for impairment testing, the key assumptions used, and the sensitivity of the impairment charge to changes in those assumptions. For goodwill, the applicant must identify each CGU or group of CGUs to which the goodwill has been allocated. The Guide further states that if the recoverable amount is based on value-in-use (VIU) calculations, the pre-tax discount rate applied must be disclosed, along with the source of the cash flow projections (e.g., board-approved budgets for the next five years).

The Stricter Standard for Pre-IPO Applicants

The HKEX has made it clear that pre-IPO companies face a higher evidentiary bar than existing listed issuers. In its 2025 Guidance Letter (GL56-2025), the Exchange stated that it expects the sponsor and reporting accountant to perform independent sensitivity analyses on all material impairment assumptions. This is not a mere recitation of management’s numbers. The Guidance Letter specifically requires a “worst-case scenario” analysis where the key assumption (e.g., revenue growth rate, gross margin, discount rate) is moved by a defined percentage (typically 10%) and the impact on the impairment charge is quantified. If a 10% adverse change in a single assumption would eliminate the headroom (i.e., the excess of recoverable amount over carrying amount), the applicant must disclose that fact and explain the likelihood of such a scenario occurring.

The Role of HKAS 36 and the 2024 IASB Amendments

Hong Kong Accounting Standard (HKAS) 36 Impairment of Assets is the foundational accounting standard. The 2024 IASB amendments, which the HKICPA adopted in full via HKAS 36 (2025), introduced two key changes for pre-IPO disclosure. First, an entity must now disclose the “key assumptions” used in its VIU calculations and, for each assumption, a “sensitivity analysis” showing how the recoverable amount would change if the assumption varied by a reasonably possible amount. Second, the amendments require disclosure of the “period over which cash flows are projected” and the “growth rate used to extrapolate cash flows beyond that period.” For pre-IPO applicants, this means the terminal value growth rate must be explicitly stated and justified against long-term industry averages or GDP growth rates. The HKEX has indicated it will reject any terminal value growth rate exceeding 3% without a detailed, independent justification from the sponsor.

Practical Compliance: Structuring the Impairment Test

CGU Allocation: The Critical First Step

The allocation of goodwill to CGUs is the single most scrutinised area by the HKEX. A common error is to allocate goodwill to a single, company-wide CGU, which the Exchange considers insufficient for testing recoverability. In its 2024 Review of Listing Documents, the HKEX found that 38% of pre-IPO prospectuses failed to clearly identify the CGU or group of CGUs to which goodwill was allocated. The correct approach, per HKAS 36.80, is to allocate goodwill to each CGU (or group of CGUs) that is expected to benefit from the synergies of the business combination. For a multi-product or multi-region company, this typically means allocating goodwill to the lowest level at which management monitors the return on investment. The prospectus must include a table showing the carrying amount of goodwill allocated to each CGU, the basis of allocation (e.g., relative fair value at acquisition), and the recoverable amount for each CGU.

Discount Rate Justification: From a Range to a Single Point

The discount rate used in VIU calculations must be a pre-tax rate that reflects the current market assessment of the time value of money and the risks specific to the asset. The HKEX expects the applicant to derive this rate using a Weighted Average Cost of Capital (WACC) approach, then gross it up for tax. The Guidance Letter requires disclosure of the following components: the risk-free rate (typically the Hong Kong Exchange Fund Notes or US Treasury yield for the relevant duration), the equity risk premium, the beta (levered and unlevered), the cost of debt, and the tax rate. The applicant must also disclose the source of each input (e.g., Bloomberg, Damodaran, or an independent valuation firm). If the discount rate is a single point (e.g., 12.5%), the prospectus must also disclose the range of reasonably possible rates (e.g., 11.0% to 14.0%) and the impact on the impairment charge if the rate were at the upper or lower end of that range. The HKEX has flagged cases where a 1 percentage point change in the discount rate eliminated all headroom, and those applicants were required to include a specific risk factor in the “Risk Factors” section of the prospectus.

Terminal Value and Growth Rate: The Most Contested Assumption

The terminal value often accounts for 60-80% of the total VIU for a mature business. The HKEX’s 2025 Guidance Letter explicitly states that a terminal value growth rate exceeding the long-term nominal GDP growth rate of the principal market (e.g., 3.5% for China, 2.5% for Hong Kong) is presumptively unreasonable. For a company with a 5-year explicit forecast period and a terminal growth rate of 4%, the applicant must provide a detailed justification, including independent market research showing that the industry is expected to grow at that rate indefinitely. The Guidance Letter also requires a “terminal value sensitivity table” showing the impact on the impairment charge if the terminal growth rate is reduced by 0.5%, 1.0%, and 1.5%. If a 1.0% reduction eliminates headroom, the applicant must disclose that the impairment test is “highly sensitive” to this assumption and include a corresponding risk factor.

Disclosure in the Prospectus: What the HKEX Expects

The “Critical Accounting Estimates” Section

The prospectus must contain a dedicated “Critical Accounting Estimates and Judgements” section that discusses goodwill and intangible asset impairment. This section must be written in plain English and avoid boilerplate language. The HKEX’s 2024 Review of Listing Documents found that 45% of prospectuses used generic phrases like “management uses its best estimates” without providing the specific estimates or the range of possible outcomes. The acceptable approach is to state the specific assumption (e.g., “revenue growth rate of 8% for the next five years”), the basis for that assumption (e.g., “based on historical growth of 7% and a new product launch expected to add 1%”), and the sensitivity (e.g., “a 1% decrease in revenue growth would reduce headroom by HKD 50 million”). The Guidance Letter requires that the sensitivity analysis cover at least three scenarios: base case, upside case (e.g., 10% higher revenue growth), and downside case (e.g., 10% lower revenue growth).

Sponsor and Reporting Accountant Responsibilities

The sponsor is responsible for ensuring that the impairment testing disclosures are complete and consistent with the financial statements. The reporting accountant (auditor) must issue a “report on the profit forecast and the impairment test” as part of the sponsor’s due diligence. The SFC Code of Conduct (paragraph 17.6) requires the sponsor to “take reasonable steps to satisfy itself that the assumptions on which the profit forecast is based are reasonable.” For impairment testing, this means the sponsor must independently verify the cash flow projections against the applicant’s historical performance, industry benchmarks, and macroeconomic data. The HKEX Guidance Letter (GL56-2025) further requires the sponsor to document its challenge of management’s key assumptions, including the discount rate and terminal growth rate, and to include this documentation in the listing application.

Risk Factor Disclosure: When Impairment is Material

If the impairment test shows that a reasonably possible change in a key assumption would result in an impairment charge exceeding 5% of the applicant’s net profit or 2% of its total assets, the applicant must include a specific risk factor in the “Risk Factors” section. The risk factor must state the carrying amount of the goodwill or intangible asset, the key assumption, the sensitivity, and the potential impairment charge. For example: “As at 31 December 2025, the Group had goodwill of HKD 500 million allocated to its retail CGU. A 1% decrease in the terminal growth rate from 3.0% to 2.0% would result in an impairment charge of HKD 45 million, representing 8% of the Group’s net profit for the year ended 31 December 2025.” The HKEX has rejected applications where the risk factor was generic and did not reference the specific goodwill balance or the specific assumption.

Post-Listing Obligations and Continuous Disclosure

Annual Impairment Testing and Quarterly Updates

After listing, the issuer must perform goodwill impairment testing at least annually, or more frequently if there is an indicator of impairment (HKAS 36.9). The Listing Rules (Main Board Rule 13.09 and GEM Rule 17.10) require immediate disclosure of any material impairment charge. The HKEX has issued a Guidance Letter (GL58-2025) clarifying that an impairment charge exceeding 5% of the issuer’s market capitalisation or 10% of its net profit is considered “material” and must be announced as soon as practicable. For pre-IPO applicants, this means the prospectus must include a discussion of the post-listing disclosure obligations and the specific triggers that would require an announcement.

The Impact of the 2024 IASB Amendments on Post-Listing Reports

The 2024 IASB amendments require that the annual report disclose the “key assumptions” used in the impairment test and a “sensitivity analysis” for each assumption. For listed issuers, this means the annual report must include a table showing the carrying amount of goodwill by CGU, the recoverable amount, the key assumptions, and the sensitivity. The amendments also require disclosure of the “period over which cash flows are projected” and the “growth rate used to extrapolate cash flows beyond that period.” The HKEX’s Corporate Governance Code (CG Code, effective 2025) requires that the audit committee review the impairment testing methodology and the key assumptions, and report its findings to the board. The board must then confirm in the annual report that the impairment test is “reasonable and supportable.”

Enforcement Trends: What the SFC and HKEX Are Targeting

The SFC’s 2024 Enforcement Report identified goodwill impairment as a “high-risk area” for financial misstatement. The SFC has taken enforcement action against three listed issuers in 2024 for failing to impair goodwill when indicators of impairment were present, resulting in overstatements of HKD 1.2 billion in aggregate. The SFC’s Guidelines on Disclosure of Financial Information (2024 edition) specifically require that issuers disclose the “basis for concluding that no impairment is required” when the recoverable amount only marginally exceeds the carrying amount. For pre-IPO applicants, this means the prospectus must include a clear statement of the headroom (the excess of recoverable amount over carrying amount) and the margin of safety. If the headroom is less than 20% of the carrying amount, the applicant must disclose that the impairment test is “highly sensitive” and include a corresponding risk factor.

Actionable Takeaways

1. Allocate goodwill to the lowest level CGU that management monitors for return on investment, and disclose the allocation basis and carrying amount in a dedicated table in the prospectus. This is the single most common deficiency identified by the HKEX in pre-IPO reviews.

2. Derive the discount rate using a WACC approach, disclose all components with their sources, and include a sensitivity table showing the impact of a 1 percentage point change. A single-point discount rate without a range will be challenged by the Exchange.

3. Cap the terminal value growth rate at or below the long-term nominal GDP growth rate of the principal market, and provide independent market research to justify any higher rate. A terminal growth rate above 3% is presumptively unreasonable and will require detailed sponsor justification.

4. Include a “worst-case scenario” sensitivity analysis where each key assumption is moved by 10%, and disclose the impact on the impairment charge. If a 10% adverse change eliminates headroom, include a specific risk factor in the “Risk Factors” section.

5. Engage the reporting accountant to perform an independent sensitivity analysis on all material impairment assumptions, and document the sponsor’s challenge of management’s assumptions in the listing application. The SFC and HKEX now expect this level of scrutiny as a matter of course.
