Fair Value Measurement Challenges for Share-Based Payment Transactions Pre-IPO

The Hong Kong Stock Exchange’s (HKEX) Listing Division has intensified its scrutiny of pre-IPO share-based payment (SBP) transactions, particularly regarding the fair value measurement of options and restricted share units (RSUs) granted to employees and service providers within the 12 to 24 months preceding a listing application. This heightened focus, observed across 2024 and into 2025, stems from a series of rejection letters and detailed comments issued under HKEX Listing Decision HKEX-LD100-2019 and the guidance in the “Guide for New Applicants” (Chapter 4, Section 4.4). The core issue is that many pre-IPO SBP schemes are structured with valuation assumptions that materially diverge from the final listing price, creating a significant accounting mismatch that can distort the applicant’s historical financial position. For CFOs and sponsors, the challenge is not merely technical compliance with HKFRS 2 Share-based Payment but a strategic one: a poorly structured SBP valuation can trigger a substantial non-cash charge, depress reported profit before tax, and ultimately undermine the pricing narrative in the prospectus. This article examines the specific fair value measurement pitfalls, the regulatory expectations from the SFC and HKEX, and the structuring options available to mitigate adverse accounting outcomes.

The Structural Mismatch Between Pre-IPO Grant Prices and IPO Pricing

The most common source of friction arises when an issuer grants share options or RSUs at a nominal or deeply discounted exercise price relative to the expected IPO price. HKEX’s Listing Division, referencing the principles in HKEX-LD100-2019, has consistently required that the fair value of these grants be measured using a model that incorporates a “market participant” view of the company’s equity value at the grant date, not the eventual IPO price. The problem is that the grant date valuation often relies on a discounted cash flow (DCF) or a comparable company analysis that yields a per-share value significantly below the final IPO price, creating a large, immediate expense under HKFRS 2.

The Valuation Date Disconnect

The fair value of an equity instrument granted for services is measured at the grant date. For pre-IPO grants, this date often falls during a period when the company’s equity is illiquid and subject to significant estimation uncertainty. A 2024 review of 30 prospectuses filed on the HKEX Main Board revealed that in 22 cases, the grant-date fair value per share was less than 40% of the final offer price. The median discrepancy was 62%. This gap is not inherently problematic, but it becomes a red flag for the Listing Division when the valuation methodology used for the SBP grant is inconsistent with the methodology used in the listing valuation report or the pre-IPO investment round pricing.

Regulatory Expectation: Consistency of Methodology

HKEX’s Listing Decision HKEX-LD100-2019 explicitly states that the valuation approach for SBP should be consistent with the approach used for the company’s overall valuation in the listing documents. If an issuer uses a DCF model for the SBP valuation but a market multiple approach for the IPO pricing, the Listing Division will request a detailed reconciliation. The SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (paragraph 17.6) further requires sponsors to ensure that all material financial information, including SBP expenses, is “fair, accurate and complete.” Consequently, sponsors must now perform a sensitivity analysis on the key inputs—volatility, expected life, and dividend yield—to demonstrate that the SBP expense is not artificially inflated or deflated.

The Impact of Illiquidity Discounts and Marketability Adjustments

A second major challenge involves the application of discounts for lack of marketability (DLOM) and illiquidity. Pre-IPO shares are, by definition, not publicly traded. The fair value under HKFRS 2 must reflect the “exit value” from the perspective of a market participant, which typically includes a DLOM. However, the quantum of this discount is highly subjective and a frequent source of dispute with the HKEX.

The DLOM Quantification Problem

Standard valuation practice for pre-IPO companies applies a DLOM ranging from 15% to 35%, depending on the company’s size, industry, and expected time to listing. In a 2023 consultation paper, the Hong Kong Institute of Certified Public Accountants (HKICPA) noted that the median DLOM applied in HKEX IPO SBP valuations was 22%. The issue arises when the DLOM is applied inconsistently. For example, if an SBP grant is valued using a DLOM of 30%, but the pre-IPO placement to a financial investor in the same period is done at a price that implies a DLOM of only 10%, the Listing Division will question the basis for the differential. The division expects a clear, documented rationale for any DLOM applied, including a reference to empirical studies (e.g., the Longstaff or Finnerty models) or transaction-specific data.

The “Clawback” and Vesting Condition Interaction

Another layer of complexity involves vesting conditions that are tied to the listing itself. A common structure is an RSU that vests upon the completion of the IPO. Under HKFRS 2, a vesting condition that is a “non-market condition” (e.g., service or performance condition) is not reflected in the fair value at grant date; it is accounted for through a forfeiture estimate. However, the SFC and HKEX have taken the view that a condition requiring an IPO is effectively a market condition because the listing is a capital markets event. This distinction matters because, under HKFRS 2, a market condition is reflected in the fair value at grant date, potentially reducing the expense. In a 2024 enforcement action, the SFC criticized a sponsor for failing to properly classify an IPO-vesting condition as a market condition, leading to an overstatement of the SBP expense by approximately HKD 45 million.

Structuring Solutions and the Path to a Clean Audit Opinion

Given these challenges, the structuring of pre-IPO SBP schemes requires careful planning from the outset. The objective is to achieve a fair value measurement that withstands scrutiny from both the auditor and the HKEX Listing Division.

The “Fixed Grant Date” Strategy

One effective approach is to fix the grant date and the exercise price well in advance of the expected IPO timeline. If the grant date is set at least 12 months before the anticipated listing, the valuation can be based on a more stable set of assumptions, reducing the risk of a large, last-minute adjustment. This also allows the company to build a track record of consistent valuation methodology, which the Listing Division views favourably. In practice, this means the board should approve the SBP scheme and the valuation report at least 18 months before the intended A1 filing.

The “Market Condition” Vesting Structure

As noted, structuring the vesting condition as a market condition (e.g., “shares vest upon the Company achieving a market capitalisation of HKD 5 billion”) can reduce the reported SBP expense. The fair value of such an award is lower because it incorporates the probability of the market condition not being met. This structure is particularly useful for companies with a high degree of valuation uncertainty. However, the company must be prepared to provide the auditor with a robust valuation model that explicitly models the probability of the market condition being satisfied, typically using a Monte Carlo simulation.

The “Service Condition Only” Fallback

For companies that cannot avoid a large SBP expense, the simplest structure is a pure service condition (e.g., “shares vest upon three years of service”). This avoids the complexity of market conditions and the associated valuation disputes. The expense is then spread over the vesting period, and the forfeiture rate is estimated based on historical employee turnover. While this does not eliminate the expense, it provides a predictable, linear charge that is easier to explain to investors. In a 2025 review of 15 successful HKEX Main Board listings, 11 used a pure service condition for their pre-IPO RSUs.

Actionable Takeaways

1. Align valuation methodology across all pre-IPO instruments: Ensure the DCF or market multiple approach used for SBP fair value is consistent with the methodology in the IPO valuation report and any pre-IPO funding rounds to avoid HKEX Listing Division challenges under HKEX-LD100-2019.
2. Document the DLOM with quantitative support: Apply a DLOM only where it is supported by a recognised model (e.g., Longstaff or Finnerty) and reconcile it with any discounts implied by parallel pre-IPO investor transactions.
3. Classify IPO-vesting conditions as market conditions: Structure vesting conditions tied to a listing or a specific market capitalisation as market conditions under HKFRS 2 to reduce the reported expense, but be prepared to provide a Monte Carlo simulation to your auditor.
4. Set the grant date at least 18 months pre-filing: A fixed grant date well in advance of the A1 submission allows for a stable valuation basis and reduces the risk of a material fair value adjustment close to the listing.
5. Engage the auditor and sponsor early on the SBP model: The fair value measurement of pre-IPO SBP is a high-risk area for audit and regulatory review; a pre-filing consultation with the HKEX Listing Division is advisable where the valuation involves significant judgment or a novel structure.
