Handling Financial Data Comparability Issues in IPO Prospectuses

The Hong Kong Stock Exchange’s (HKEX) December 2024 consultation on listing regime enhancements, which proposed codifying a minimum 28-day pre-deal research period for new applicants, has placed a sharp focus on the integrity of financial disclosures in IPO prospectuses. This regulatory push, expected to be finalised in H1 2025, arrives as the Listing Division intensifies scrutiny on historical financial information that lacks comparability across reporting periods. For CFOs and company secretaries preparing for a Main Board or GEM listing, the single most common reason for extended comment letters from the HKEX is not revenue recognition or related-party transactions—it is the failure to present financial data in a manner that allows a direct, like-for-like comparison across the three full financial years required under the Listing Rules. A 2023 internal HKEX study of 47 rejected IPO applications found that 31 (65.9%) involved at least one material comparability issue, ranging from inconsistent segment reporting to unaudited pro forma adjustments that did not comply with the Hong Kong Financial Reporting Standards (HKFRS). This article outlines the specific regulatory requirements, common pitfalls, and structural solutions for handling financial data comparability in prospectus disclosures, with direct references to the relevant chapters of the Main Board and GEM Listing Rules.

The Regulatory Framework for Comparability Under the Listing Rules

The Three-Year Track Record Requirement and Its Comparability Implications

The foundation of any IPO prospectus financial section is the requirement under Main Board Rule 4.04(1) and GEM Rule 7.03(1) that the issuer must present audited financial statements for at least three full financial years immediately preceding the listing application. This requirement is not merely a backward-looking compliance exercise—it is the primary mechanism by which the HKEX assesses the issuer’s financial stability, growth trajectory, and the sustainability of its business model. The critical comparability issue arises when the issuer has undergone structural changes during that three-year window—such as acquisitions, disposals, changes in accounting policies, or modifications to the group structure—that render a direct year-on-year comparison misleading without appropriate adjustments.

The HKEX’s Listing Decision LD43-3 (2012) remains the definitive guidance on this point, stating unequivocally that where an issuer has acquired a business during the track record period, the financial statements must be presented on a combined or consolidated basis as if the acquisition had occurred at the beginning of the track record period. This requirement applies even if the acquisition was structured as a business combination under HKFRS 3, and the issuer must disclose the pro forma effects of the acquisition on each line item for all periods presented. In practice, this means the CFO must prepare a set of combined financial statements that retroactively integrate the acquired entity’s results, assets, and liabilities for the entire three-year period, with full disclosure of the basis of combination and any material assumptions.

The Role of Accounting Policy Consistency in Prospectus Disclosures

Under HKFRS, specifically HKAS 8 (Accounting Policies, Changes in Accounting Estimates and Errors), an entity must apply its accounting policies consistently for similar transactions and events across reporting periods. This principle is embedded in the Listing Rules through Main Board Rule 4.06(1) and GEM Rule 7.10(1), which require that the accounting policies used in the prospectus financial statements must be consistent with those used in the issuer’s published annual financial statements for the track record period. Where an issuer has changed an accounting policy during the track record period—for example, switching from the cost model to the revaluation model for investment properties under HKAS 40—the comparability requirement mandates retrospective restatement of all prior period figures as if the new policy had always been applied.

A 2024 review by the SFC of 22 IPO prospectuses filed in Q1 2024 revealed that 8 (36.4%) contained at least one instance where changes in accounting policies were not properly restated in the comparative figures. The most common errors involved revenue recognition policies under HKFRS 15, where issuers had changed their method of recognising revenue from a point-in-time basis to an over-time basis without fully restating the prior year comparatives. The SFC’s enforcement division has indicated that such omissions can constitute a material misstatement under Section 384 of the Securities and Futures Ordinance (Cap. 571), potentially exposing the directors and the sponsor to civil liability.

Common Comparability Challenges and Their Resolution

Business Combinations and Acquisitions During the Track Record Period

The most frequent comparability issue encountered by the HKEX Listing Division involves business combinations completed during the three-year track record period. When an issuer acquires a subsidiary, associate, or joint venture after the start of the track record period, the financial statements must be presented as if the acquisition had occurred at the beginning of the earliest period presented. This is not merely a pro forma adjustment—it requires the preparation of combined financial statements that aggregate the acquired entity’s results from the start of the track record period, with the acquisition date being the date from which control was actually obtained under HKFRS 10.

The technical challenge lies in the fact that the acquired entity may have maintained its own accounting records under a different accounting framework, such as PRC GAAP or US GAAP, rather than HKFRS. The issuer must therefore perform a full HKFRS conversion of the acquired entity’s financial statements for the entire pre-acquisition period, ensuring that all accounting policies are aligned with the issuer’s policies. This process typically requires the engagement of a second set of auditors to perform an audit on the acquired entity’s HKFRS-compliant financial statements for the pre-acquisition period, adding significant cost and time to the listing timeline.

A practical example from the 2023 listing of a PRC-based consumer goods company on the Main Board illustrates the complexity. The issuer had acquired a manufacturing subsidiary in January 2022, but the track record period covered the years ended 31 December 2021, 2022, and 2023. The HKEX required the issuer to present combined financial statements for 2021 as if the subsidiary had been part of the group from 1 January 2021, even though the subsidiary was a separate legal entity under different ownership at that time. The issuer had to reconstruct the subsidiary’s 2021 financial records from its PRC GAAP-based management accounts, applying HKFRS adjustments for revenue recognition, inventory valuation, and deferred tax—a process that took five months and required two rounds of HKEX comment letters before acceptance.

Changes in Reporting Entity Structure and Group Reorganisations

Another significant comparability challenge arises from group reorganisations that alter the reporting entity structure during the track record period. When an issuer transfers assets, liabilities, or entire business divisions between group entities, or when the group structure is simplified through the elimination of intermediate holding companies, the financial statements must be restated to reflect the new structure for all periods presented. This requirement is grounded in the principle that the prospectus financial statements must present the issuer’s financial position and performance as if the current group structure had always existed.

The HKEX’s Listing Decision LD100-2019 provides specific guidance on this point, stating that where a group reorganisation involves the transfer of a business between entities under common control, the financial statements should be presented using the pooling of interests method as described in HKAS 8, rather than the acquisition method under HKFRS 3. This is a critical distinction because the pooling of interests method does not recognise goodwill or bargain purchase gains, and it requires the restatement of all comparative periods as if the entities had always been combined. The issuer must disclose in the notes to the financial statements the basis of the reorganisation, the entities involved, the date of the transfer, and the effect on each line item for all periods presented.

In practice, this requirement often creates tension with the issuer’s desire to present a simplified group structure in the prospectus. A 2024 HKEX comment letter to a GEM applicant noted that the issuer had eliminated an intermediate holding company in June 2023 but had not restated the 2022 comparative figures to reflect the simplified structure. The HKEX required the issuer to refile the financial statements with full restatement, adding six weeks to the listing timeline and incurring additional audit fees of approximately HKD 450,000.

Technical Solutions for Ensuring Comparability

The Use of Pro Forma Financial Information Under HKFRS and Listing Rules

Pro forma financial information is a legitimate tool for addressing comparability issues, but its use is strictly circumscribed by the Listing Rules and the SFC’s Code of Conduct. Main Board Rule 4.29(1) and GEM Rule 7.28(1) permit the inclusion of pro forma financial information in the prospectus only where it is necessary to illustrate the impact of a material transaction or event that has occurred or is expected to occur. The pro forma adjustments must be clearly identified, explained, and supported by a responsible party’s report, typically from the reporting accountants.

The critical requirement for comparability purposes is that pro forma information must not be presented in a manner that suggests it is a substitute for the audited historical financial statements. The HKEX’s Guidance Letter GL41-12 (2012) specifies that pro forma financial information must be presented in a separate section of the prospectus, clearly labelled as unaudited, and accompanied by a statement that it is provided for illustrative purposes only. The adjustments must be directly attributable to the transaction, factually supportable, and expected to have a continuing effect on the issuer’s financial position or results.

A common error occurs when issuers attempt to use pro forma adjustments to correct comparability issues arising from business combinations or group reorganisations, rather than presenting combined financial statements as required by LD43-3. The HKEX has rejected multiple prospectuses where the issuer presented pro forma financial information that effectively restated the track record period as if the acquisition had occurred at the start, without first presenting the audited combined financial statements. The correct approach is to present the combined financial statements as the primary historical financial information, with pro forma adjustments limited to events that occurred after the end of the track record period, such as the IPO proceeds application or the repayment of acquisition-related debt.

Segment Reporting and Disaggregation of Financial Information

Comparability issues frequently arise in the presentation of segment information under HKFRS 8 (Operating Segments). The standard requires that segment information be presented on the same basis as that used for internal reporting to the chief operating decision maker (CODM). If the issuer has reorganised its internal reporting structure during the track record period—for example, by merging two previously separate operating segments—the comparability requirement under HKFRS 8.29 mandates that the segment information for all prior periods be restated to reflect the new segment structure.

The HKEX’s Listing Decision LD66-2014 addressed a case where an issuer had changed its segment reporting from a geographic basis to a product-line basis during the track record period, but had not restated the prior year comparatives. The HKEX required the issuer to present the segment information for all three years on the new product-line basis, with full disclosure of the change in segment structure and the basis of restatement. The issuer was also required to include a reconciliation between the old and new segment structures for each period, showing the revenue, profit or loss, and assets attributable to each segment under both bases.

For issuers with complex business models—such as those operating in multiple jurisdictions or across different regulatory regimes—the disaggregation of revenue under HKFRS 15.114-115 adds an additional layer of comparability complexity. The standard requires the disaggregation of revenue into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. If the issuer has changed its revenue disaggregation categories during the track record period, the prior period comparatives must be restated to conform to the new categories, with disclosure of the change and the reasons for it.

Practical Implications for the Listing Timeline and Sponsor Responsibilities

The Impact on the A1 Filing and Comment Letter Process

Comparability issues are a leading cause of extended comment letter cycles with the HKEX Listing Division. Data from the HKEX’s 2024 Annual Report indicates that the average time from A1 filing to the first listing hearing for Main Board applicants was 168 days in 2024, up from 145 days in 2023. A significant portion of this increase is attributable to the time required to resolve comparability issues raised in the Listing Division’s initial comment letters.

The sponsor bears primary responsibility under the SFC’s Code of Conduct for Corporate Finance Advisors (paragraph 17.1) for ensuring that the financial information in the prospectus is complete, accurate, and comparable across all periods presented. This requires the sponsor to conduct a thorough due diligence review of the issuer’s historical financial statements, including an assessment of any changes in accounting policies, group structure, or business combinations that could affect comparability. The sponsor must also ensure that the reporting accountants have performed the necessary procedures to support any restatements or pro forma adjustments.

A practical recommendation for CFOs is to engage the reporting accountants to prepare a comparability memorandum at the pre-A1 stage, identifying all potential comparability issues and the proposed resolution. This memorandum should be shared with the sponsor and the legal advisers, and should form the basis of the financial disclosures in the prospectus. The HKEX has indicated in informal guidance that it views such pre-emptive documentation favourably, as it demonstrates a proactive approach to compliance.

The Role of the Audit Committee in Overseeing Comparability

The audit committee of the issuer’s board of directors has a specific responsibility under the HKEX’s Corporate Governance Code (Code Provision C.3.3) to review the financial statements and ensure that they present a true and fair view of the issuer’s financial position. Where comparability issues arise, the audit committee must satisfy itself that the adjustments made to achieve comparability are appropriate, complete, and properly disclosed.

The audit committee should receive a detailed briefing from the reporting accountants on any comparability adjustments, including the basis for the adjustments, the impact on each line item, and the sensitivity of the adjustments to key assumptions. The committee should also review the pro forma financial information, if any, to ensure that it complies with the Listing Rules and does not mislead investors. Minutes of the audit committee meeting discussing these matters should be retained as part of the sponsor’s due diligence file.

Actionable Takeaways for CFOs and Company Secretaries

1. Prepare a comparability memorandum at the pre-A1 stage, identifying all changes in accounting policies, group structure, and business combinations during the track record period, with a proposed resolution for each issue supported by reference to the relevant HKFRS and Listing Rule provisions.

2. Engage the reporting accountants to perform a full HKFRS conversion of any acquired entity’s financial statements for the pre-acquisition period, and ensure that the combined financial statements are audited and presented as the primary historical financial information in the prospectus.

3. Restate segment information for all periods presented whenever the internal reporting structure changes during the track record period, and include a reconciliation between the old and new segment structures in the notes to the financial statements.

4. Limit pro forma financial information to events occurring after the end of the track record period, and ensure that pro forma adjustments are not used as a substitute for the audited combined financial statements required under Listing Decision LD43-3.

5. Document all audit committee discussions on comparability issues in formal minutes, including the basis for approving any restatements or pro forma adjustments, to demonstrate compliance with the Corporate Governance Code and support the sponsor’s due diligence file.
