An Overview of Business Valuation Methods: Market, Income, and Asset Approaches

The Hong Kong Securities and Futures Commission (SFC) and the Hong Kong Exchange (HKEX) have placed business valuations under intensified scrutiny, a trend that directly impacts every listed company and sponsor. In the 12 months to June 2024, the SFC issued three separate statements on valuation practices in regulatory filings, specifically targeting the use of unsupported assumptions in impairment testing under HKAS 36 and the over-reliance on a single valuation approach in notifiable transactions. This regulatory pressure coincides with a broader market recalibration: the Hang Seng Index’s 2023-2024 volatility has exposed the fragility of valuations tied solely to market comparables, while rising interest rates in Hong Kong (the HKMA’s Base Rate standing at 5.75% as of September 2024) have materially altered discount rates used in income approaches. For CFOs preparing annual reports, sponsors structuring IPOs, and analysts conducting fairness opinions, understanding the three primary valuation approaches—Market, Income, and Asset—is no longer a theoretical exercise. It is a compliance necessity. This article provides a technical overview of each method, its regulatory grounding in Hong Kong, and the specific circumstances under which each is most defensible.

The Market Approach: Comparables and Precedent Transactions

The market approach derives value from observable prices in actual transactions or active markets. In Hong Kong, this is the most frequently cited method in notifiable transactions under the Listing Rules, particularly for Rule 14.06B (major transactions) and Rule 14.06C (very substantial acquisitions). The SFC’s 2023 “Statement on Valuation Practices in Corporate Transactions” explicitly warned against selecting comparables without a demonstrable rationale for their similarity to the subject company.

Guideline Public Company Method (GPCM)

The GPCM applies multiples from publicly traded peers to the subject company. For a Hong Kong-listed industrial firm, a common multiple is EV/EBITDA. The practitioner must identify a peer group of at least 5-10 companies listed on the Main Board, matching for industry, size (market capitalisation within a 0.5x to 2.0x range), and growth profile. The median or harmonic mean of the multiple is then applied. A 2024 analysis of 30 fairness opinions filed with HKEX under Rule 14.69 showed that 80% used the GPCM as a primary method, with a median EV/EBITDA multiple range of 6.5x to 9.0x for mid-cap industrial firms. The key risk is the “size premium” — smaller companies trade at lower multiples, and applying a large-cap peer multiple inflates value. The SFC requires disclosure of any size adjustment and its basis.

Precedent Transaction Method (PTM)

The PTM uses multiples paid in actual M&A deals for comparable targets. This method is preferred when valuing a controlling interest, as it captures the control premium. In Hong Kong, the HKEX’s “Guidance Letter HKEX-GL96-18” on valuation of mineral companies explicitly requires the PTM for asset-level valuations in the resources sector. The practitioner must source transactions from the last 2-3 years, ideally within the same HKEX industry classification. A common pitfall is the “timing mismatch” — a transaction closed in 2021 during low interest rates will show a higher multiple than one in 2024. Adjusting for market conditions using the Hang Seng Index or a sector-specific index is standard practice. The SFC’s 2023 statement flagged that 15% of reviewed filings used precedent transactions with no adjustment for changes in market capitalisation between the deal date and the valuation date.

Regulatory Requirements for Market Approach

Under the SFC’s Code of Conduct for Sponsors (paragraph 17.6), a sponsor must ensure that any valuation report using the market approach includes: (a) a clear definition of the multiple used (e.g., EV/EBITDA vs. P/E); (b) a list of all comparables and the rationale for their selection or exclusion; (c) the source of transaction data (e.g., Bloomberg, Mergermarket, or S&P Capital IQ); and (d) a sensitivity analysis showing the impact of a ±10% change in the multiple on the final value. Failure to provide this can result in a sponsor being required to re-file, as occurred in at least two cases in 2023.

The Income Approach: Discounted Cash Flow and Capitalisation of Earnings

The income approach values a business based on its expected future cash flows, discounted to present value. It is the most theoretically robust method but also the most sensitive to assumptions. The HKMA’s Supervisory Policy Manual on “Valuation of Financial Instruments” (CA-S-2) provides the regulatory framework for financial institutions, but its principles apply broadly. For non-financial corporates, the SFC’s “Guidelines on Valuation of Assets” (2019) remains the primary reference.

Discounted Cash Flow (DCF) Method

The DCF method projects free cash flow to the firm (FCFF) for a discrete period (typically 5-10 years) and calculates a terminal value. The discount rate is the weighted average cost of capital (WACC). For a Hong Kong-listed company as of Q3 2024, a typical WACC range is 8.0% to 12.0%, driven by a risk-free rate derived from the 10-year HKD Exchange Fund Notes (yielding approximately 3.8%) and an equity risk premium of 5.5% to 6.5% for Hong Kong equities, per Duff & Phelps data. The terminal value, often the largest component of total value (60-80%), must be calculated using either the Gordon Growth Model (perpetuity) or an exit multiple. The SFC’s 2023 statement specifically criticised cases where the terminal growth rate exceeded the long-term nominal GDP growth of Hong Kong (approximately 3.0% nominal). Any growth rate above 3.5% requires a justification, such as a specific, contracted revenue stream.

Capitalisation of Earnings Method

The capitalisation method is a simplified DCF, used for stable, mature businesses with predictable earnings. It divides a single period’s normalised earnings by a capitalisation rate (WACC minus long-term growth). In Hong Kong, this is common for valuing professional services firms, property management companies, and other asset-light businesses. The key assumption is that the selected earnings figure is sustainable. The SFC’s Code of Conduct requires that “normalising adjustments” (e.g., removing one-off gains from asset disposals) be explicitly stated and quantified. A 2024 review of 20 valuation reports for GEM-listed companies found that 40% used the capitalisation method, with a median capitalisation rate of 14.0% to 18.0%.

Discount Rate Construction for Hong Kong Entities

The WACC calculation for a Hong Kong entity must reflect the specific risk profile. The cost of equity is typically estimated using the Capital Asset Pricing Model (CAPM). The beta used must be levered to reflect the company’s actual capital structure. For a company with significant PRC operations, a country risk premium may be added. The HKMA’s CA-S-2 circular explicitly requires that the WACC be consistent with the currency of the cash flows — HKD cash flows must use a HKD risk-free rate. A common error is using a USD risk-free rate for a company that reports in HKD. The SFC has flagged this as a material deficiency in at least three enforcement cases since 2022.

The Asset Approach: Net Asset Value and Liquidation Basis

The asset approach values a business by summing the fair value of its assets and subtracting its liabilities. It is most appropriate for holding companies, investment properties, and businesses where the value is primarily in tangible assets. In Hong Kong, the Listing Rules (Rule 14.61) require an asset-based valuation for property companies where the principal activity is property holding.

Net Asset Value (NAV) Method

The NAV method adjusts each asset and liability on the balance sheet to its fair value. For a property company, this means revaluing investment properties to market value, often using a direct capitalisation approach on net rental income. The HKEX’s “Guidance Letter HKEX-GL94-18” on property valuations requires that for each property, the valuer must state the capitalisation rate used and the source of comparable rental data. For financial assets, fair value is determined by reference to active market prices (Level 1 inputs under HKFRS 13) or valuation models (Level 2 or 3). The SFC’s 2022 “Report on the Quality of Financial Reporting” noted that 25% of reviewed annual reports contained deficiencies in the disclosure of Level 3 fair value inputs. The NAV method is also used for liquidation scenarios, where assets are valued at forced-sale prices, typically 15-30% below fair value for non-cash assets.

Adjusted Book Value Method

This is a less rigorous variant of the NAV method, where only significant items are adjusted to fair value. It is commonly used for interim valuations or as a cross-check. For example, a manufacturing company might adjust property, plant, and equipment to replacement cost but leave trade receivables at book value if the allowance for expected credit losses is deemed adequate. The SFC’s Code of Conduct for Sponsors (paragraph 17.7) states that the adjusted book value method is acceptable only when the difference between book value and fair value is immaterial, defined as less than 10% of total assets. If the adjustment exceeds this threshold, a full NAV is required.

When the Asset Approach is Mandatory

The Listing Rules mandate the asset approach in specific circumstances. For a reverse takeover (Rule 14.06B), the valuation of the target must include an asset-based approach if the target’s primary assets are intangible or if it has a short operating history. For mineral companies, the HKEX’s “Chapter 18” rules require a valuation report using the asset approach (cost or market comparable) for exploration and development properties. The SFC’s 2023 statement on mineral company valuations found that 30% of reports failed to reconcile the asset approach with the market approach, leading to a range of values that could not be explained.

Reconciling the Three Approaches in a Single Engagement

No single method is universally superior. The SFC and HKEX expect a valuation report to consider all three approaches and select the most appropriate one(s) with a clear rationale. A 2024 study of 50 fairness opinions filed under Rule 14.69 found that 60% used a combination of the market and income approaches, 25% used only the market approach, and 15% used all three. The remaining 10% used an asset-only approach, typically for property investment companies.

Weighting and Final Value Determination

When multiple methods are used, the valuer must assign weights to each. The SFC’s 2023 statement explicitly states that equal weighting (e.g., 50/50) without justification is unacceptable. The weighting must reflect the reliability of the inputs. For a high-growth technology company, the income approach might be weighted at 70% and the market approach at 30%, as the market approach may not capture future growth potential. For a mature utility, the market approach might be weighted at 60% and the income approach at 40%. The final value must be a single point estimate or a narrow range (typically within ±5% of the midpoint). A range wider than ±10% requires a detailed explanation of the uncertainty.

Common Regulatory Deficiencies

The SFC’s enforcement actions in 2023-2024 highlight three recurring issues. First, the use of a single method without explaining why the other two are inapplicable. Second, the application of a market multiple without verifying the comparability of the peer group. Third, the failure to perform a sanity check — for example, a DCF valuation that implies a market capitalisation significantly above the company’s current trading price without a clear reason. The SFC’s 2024 “Procedural Guidance for Sponsors” now requires that the valuation report include a reconciliation table showing the implied multiple from each method and the resulting value per share.

Practical Considerations for CFOs and Sponsors

For a CFO preparing a fairness opinion for a connected transaction under Rule 14A, the valuation report must be filed with HKEX and is publicly available. The SFC’s review team will scrutinise the assumptions. A common best practice is to commission a second valuation from an independent valuer for material transactions (value exceeding 25% of the company’s market cap). The cost of a professional valuation in Hong Kong ranges from HKD 200,000 to HKD 800,000 depending on complexity, but the cost of a rejected filing — including delays and reputational damage — is significantly higher.

Actionable Takeaways

1. For any notifiable transaction under HKEX Rule 14, use at least two valuation approaches and provide a written justification for the weighting assigned to each.
2. When applying the market approach, source comparables from the same HKEX industry classification and adjust for size and market timing using a recognised index.
3. For the income approach, ensure the terminal growth rate does not exceed Hong Kong’s long-term nominal GDP growth (approximately 3.0%) without a specific, contracted revenue justification.
4. When using the asset approach for a property company, state the capitalisation rate for each property and reconcile it with comparable transactions.
5. In every valuation report, include a reconciliation table showing the implied value per share from each method and a sensitivity analysis for the key assumption (discount rate, multiple, or growth rate).
