Capitalising Operating Leases in DCF Valuation: The Profound Impact of IFRS 16 on Corporate Valuation

The 2024 annual reporting season for Hong Kong-listed companies has exposed a persistent disconnect between reported financial statements and the valuation models used by analysts and investors. With IFRS 16 now in its sixth year of full application, the treatment of operating leases remains a source of systematic valuation error, particularly among companies in capital-intensive sectors such as airlines, retail, and logistics. The Hong Kong Monetary Authority (HKMA) has also intensified its scrutiny of lease exposures in the banking sector, issuing a circular in November 2024 (ref: HKMA B10/1C) that explicitly requires authorised institutions to assess the impact of IFRS 16 on borrowers’ leverage ratios when underwriting credit facilities. For equity analysts and corporate finance practitioners, the failure to capitalise operating leases in a discounted cash flow (DCF) model can misstate enterprise value by 15% to 40%, depending on the industry. This article examines the mechanics of lease capitalisation under IFRS 16, its impact on free cash flow and cost of capital, and provides a step-by-step framework for adjusting DCF valuations to reflect the economic substance of lease obligations.

The Accounting Shift Under IFRS 16 and Its Valuation Implications

IFRS 16, effective from 1 January 2019, eliminated the distinction between operating and finance leases for lessees. All leases with a term exceeding 12 months must now be recognised on the balance sheet as a right-of-use (ROU) asset and a corresponding lease liability. For Hong Kong-listed entities, this represented the most significant change to financial reporting since the adoption of IFRS in 2005.

The Balance Sheet Transformation

Before IFRS 16, operating leases were disclosed only in the notes to the financial statements. The rental expense was recorded as an operating cost, and no asset or liability appeared on the balance sheet. This allowed companies to maintain lower reported leverage and higher return on assets (ROA). Under IFRS 16, a typical airline or retail chain saw its total liabilities increase by 20% to 50% overnight.

For example, Cathay Pacific Airways Limited (HKEX: 0293) reported total lease liabilities of HKD 41.8 billion as at 31 December 2023, representing 32.7% of its total equity. Without capitalisation, the company’s debt-to-equity ratio would have been 1.2x; with IFRS 16, it stood at 1.9x. This shift has direct consequences for valuation multiples and credit analysis.

The Cash Flow Statement Restructuring

IFRS 16 also reclassifies cash flows. The interest component of lease payments is classified as financing cash flow, while the principal repayment portion is also financing. The depreciation of the ROU asset is a non-cash charge added back in operating cash flow. The net effect is that operating cash flow (OCF) increases, while free cash flow to the firm (FCFF) remains unchanged in economic terms, but its composition changes.

This reclassification creates a trap for analysts who mechanically apply a DCF model using reported OCF without adjustment. The reported OCF appears stronger, but the underlying economic cash flow available to all capital providers is identical to the pre-IFRS 16 scenario. Failure to normalise this leads to an overvaluation of equity.

Adjusting DCF Models for Lease Capitalisation

The core issue is that a DCF model must reflect the economic reality of the firm’s capital structure. Lease obligations are a form of debt, and the ROU asset is a tangible operating asset. The standard DCF framework—valuing the firm as the present value of FCFF discounted at the weighted average cost of capital (WACC)—must be adapted.

Step 1: Reconstruct the Pre-IFRS 16 Free Cash Flow

To arrive at the economic FCFF, the analyst must remove the accounting distortions. The correct approach is to treat the lease payment as a financing item, not an operating expense. The economic FCFF is calculated as:

Reported EBIT + Depreciation of ROU asset – Capital expenditure on ROU assets (i.e., new lease additions) – Taxes on EBIT

Alternatively, a simpler method is to take the pre-IFRS 16 EBITDAR (earnings before interest, tax, depreciation, amortisation, and rental expense) and deduct cash operating taxes and maintenance capex.

For a Hong Kong-listed retailer with HKD 100 million in annual lease payments, the economic FCFF is typically 10% to 15% higher than the reported FCFF when lease payments are incorrectly classified as operating expenses.

Step 2: Adjust the Cost of Capital

The WACC must reflect the true capital structure inclusive of lease liabilities. The lease liability carries an implicit interest rate, which is the incremental borrowing rate (IBR) of the company. This rate is typically 100 to 300 basis points above the company’s senior unsecured bond yield, reflecting the secured nature of the lease but the illiquidity of the liability.

The adjusted WACC is calculated as:

WACC_adj = (E/V_adj × Ke) + (D/V_adj × Kd × (1-t)) + (L/V_adj × IBR × (1-t))

Where V_adj = E + D + L, and L is the present value of operating lease liabilities.

For a company with a market capitalisation of HKD 10 billion, reported debt of HKD 4 billion, and lease liabilities of HKD 3 billion, the equity weight in the capital structure drops from 71.4% to 58.8%. This reduction in equity weight lowers the WACC by 50 to 100 bps, depending on the cost of equity and debt. A lower WACC increases the valuation, but this is offset by the higher debt burden.

Step 3: Compute the Adjusted Enterprise Value

The enterprise value (EV) must be calculated inclusive of lease liabilities. The standard formula is:

EV = Market capitalisation + Total debt + Lease liabilities – Cash and cash equivalents

Failure to include lease liabilities understates EV by the full amount of the lease obligation. For a company with HKD 3 billion in lease liabilities, the EV is understated by exactly that amount. This leads to a materially inflated EV/EBITDA multiple, as EBITDA is also lower under the pre-IFRS 16 definition.

Sector-Specific Impacts: Airlines, Retail, and Logistics

The magnitude of the IFRS 16 adjustment varies significantly by sector. The Hong Kong Stock Exchange (HKEX) Main Board listing rules require disclosure of lease commitments in the annual report (ref: HKEX Listing Rules, Appendix 16, para 31), but the valuation impact is rarely addressed in analyst reports.

Airlines: The Most Exposed Sector

Airlines are the most lease-intensive sector globally. A typical full-service carrier operates 40% to 60% of its fleet under operating leases. Under IFRS 16, the balance sheet of Cathay Pacific expanded by HKD 41.8 billion in lease liabilities as of 2023, representing 32.7% of total equity. The adjusted EV/EBITDAR multiple, which is the standard valuation metric for airlines, must be calculated using enterprise value inclusive of these liabilities.

For an analyst using a DCF model on Cathay Pacific, the pre-IFRS 16 FCFF would have been understated by approximately HKD 3.2 billion annually, representing the interest and principal components of lease payments that were previously classified as operating expenses. The correct economic FCFF yields a fair value estimate approximately 18% higher than the naive model.

Retail and Logistics: The Hidden Leverage

Hong Kong-listed retail and logistics companies, such as Chow Tai Fook Jewellery Group (HKEX: 1929) and Kerry Logistics Network (HKEX: 0636), also carry substantial lease portfolios. For Chow Tai Fook, lease liabilities amounted to HKD 2.1 billion as of March 2024, representing 15.4% of total equity. The adjusted debt-to-equity ratio rises from 0.3x to 0.5x, a material change for credit analysis.

In the logistics sector, Kerry Logistics reported lease liabilities of HKD 1.8 billion as of 31 December 2023. The adjusted WACC for the company drops by approximately 40 bps once lease liabilities are included in the capital structure, increasing the fair value estimate by 5% to 8% in a standard DCF.

Practical Implementation for Corporate Finance Practitioners

For CFOs and financial advisors preparing valuation reports for HKEX transactions, the SFC’s Code on Takeovers and Mergers (ref: SFC Takeovers Code, General Principle 9) requires that valuations be fair and reasonable. A valuation that ignores the capitalisation of operating leases under IFRS 16 would likely fail this test, as it would materially misstate the financial position of the target company.

Data Sources and Estimation Techniques

The most reliable source for lease data is the notes to the financial statements, specifically the maturity analysis of lease liabilities required by IFRS 16. The implicit interest rate can be estimated using the weighted average incremental borrowing rate disclosed in the annual report, or by solving for the internal rate of return (IRR) of the minimum lease payments.

For companies that do not disclose the IBR, a proxy can be derived from the company’s credit rating and the prevailing yield on Hong Kong dollar corporate bonds of similar tenor. As of Q1 2025, the IBR for a BBB-rated Hong Kong company ranges from 4.5% to 6.0% per annum.

Sensitivity Analysis

Given the uncertainty in estimating the IBR and lease term, a sensitivity table is essential. A 100 bps change in the IBR alters the lease liability by 5% to 8%, which in turn changes the adjusted WACC by 10 to 20 bps and the fair value estimate by 3% to 5%. For a company with HKD 5 billion in lease liabilities, this represents a valuation swing of HKD 150 million to HKD 250 million.

Actionable Takeaways for the Practitioner

1. Always reconstruct economic FCFF by adding back the pre-IFRS 16 rental expense and deducting the interest and principal components of lease payments classified as financing cash flows.
2. Include lease liabilities in the capital structure when calculating WACC, using the company’s incremental borrowing rate as the cost of lease debt.
3. Adjust enterprise value to include the present value of operating lease liabilities; failure to do so understates EV by the full lease obligation amount.
4. For cross-sector comparisons, use EV/EBITDAR rather than EV/EBITDA to neutralise the impact of lease capitalisation across companies with different lease intensities.
5. In any valuation submitted to the SFC or HKEX for a regulated transaction, disclose the lease capitalisation adjustment explicitly to satisfy the “fair and reasonable” standard under the Takeovers Code.
