APPENDIX I FURTHER INFORMATION ON THE VALUATION

I. FURTHER INFORMATION ON THE VALUATION OF SHENZHEN AIRLINES

(I) VALUATION METHODOLOGY

The asset-based approach can reflect the replacement cost of the evaluated entity on the Valuation Reference Date, and it is easy to collect the information about the evaluated entity's assets and liabilities. During the valuation, Shenzhen Airlines provided detailed breakdown list of its assets and relevant liabilities, as well as information about its assets and liabilities. The valuers also collected sufficient information required by the asset-based approach from external sources.

(1) In respect of current assets, (i) for monetary capital, accounts receivable and prepayments, the valuation determined the appraised value of such current assets based on the verified book balance and accounting and actual values, taking into consideration the recoverability, contract fulfillment and actual receipt of goods/services. The items denominated in foreign currency were converted in accordance with the central parity rates released by the People's Bank of China on the Valuation Reference Date; (ii) for inventories, except for spare parts of flight equipment which are evaluated based on net realisable value, other inventories used their verified book values as the appraised values; (2) In respect of long-term equity investment, the valuers calculated the value of the total interests of shareholders of the investees through valuation, which was multiplied by the shareholding percentage to arrive at the value of the partial interests of the shareholders; (3) For investment in other equity instruments, the appraised value was determined based on the net assets and shareholding percentage of the investees, or (where the investees are listed companies) the closing price and number of shares held on the reference date; (4) In respect of investment properties, the income approach or the market approach was adopted for the valuation; (5) In respect of the fixed assets such as equipment, the cost approach or the market approach was adopted based on the relevant conditions including the characteristics of various types of equipment, types of appraised value, collected information, etc.; (6) In respect of assets such as buildings and structures, the cost approach was mainly adopted for the valuation of self-constructed buildings, while the market approach was adopted for the valuation of buildings that were market commodity housing in nature; (7) The cost approach was adopted for the valuation of construction in progress; (8) In respect of right-of-use assets, the valuation method for right-of-use assets arising from aircraft under finance lease shall be the same as stated in (5) above; for the valuation of other right-of-use assets, given that the contractual terms of the lease were in line with those recorded on the books, no unfair contractual terms have been included, and the book vales could reflect the fair values of assets, the appraised value shall be determined based on the verified book values; (9) In respect of land use right assets, the market approach, the benchmark land price coefficient correction approach (the published land price approach) and cost approximation approach were adopted respectively for the valuation of land to be appraised; (10) In respect of other intangible assets, the income approach or the cost approach was adopted respectively based on the characteristics of assets; (11) The replacement cost approach was adopted for estimating the values of flying skills under long-term deferred expenses, while the appraised values of other long-term deferred expenses were determined based on the balance to be deferred over the remaining benefit period if the corresponding interests or assets could still be enjoyed during the future benefit period; (12) The appraised values of deferred tax assets were determined according to the valuation results of the corresponding accounting items, based on verification of differences between accounting policies and tax regulations, tax filing information and the calculation basis of income tax. The appraised values of certain items that have already been considered in the valuation of related assets were set as zero; the appraised values of the remaining items were determined either by multiplying the difference between the appraised values and the investment cost by the income tax rate, or by using the verified book values; (13) The valuation of liabilities was based on the verified authenticity of debts. Generally, the appraised values were determined based on the verified book values, with special items such as deferred income being adjusted individually according to their actual repayment or tax obligations.

II. FURTHER INFORMATION ON THE VALUATION OF AIRCRAFT

(I) VALUATION METHODOLOGY

The valuation method was selected based on the purpose of this valuation and the principle of continuous use, taking into consideration the market price, the characteristics of the evaluated equipment and availability of information. The subject of the valuation is in normal usable condition and can be obtained through replacement, and the replacement cost and the relevant depreciation can be reasonably estimated. Therefore, the cost approach was adopted for this valuation.

Appraised value = Full replacement cost × newness rate. The full replacement cost is determined with reference to the aircraft list price information, taking into account the discount rate available to the airline at the time of purchase, the taxes and fees incurred in purchasing the aircraft, and the relevant national regulatory documents. The newness rate is determined with reference to the useful life and usage conditions.

(II) VALUATION ASSUMPTIONS

I. General Assumptions

1. Transaction assumption: The transaction assumption refers to the premise that all assets subject to appraisal are hypothetically placed in the process of transaction, whereby the valuer conducts valuation by simulating market conditions based on the transaction terms of the assets subject to appraisal. The transaction assumption constitutes the most fundamental pre-requisite hypothesis enabling asset valuation to proceed.

2. Open market assumption: The open market assumption assumes that assets traded in the market or intended to be traded in the market are transacted between parties of equal standing, each having adequate time and opportunity to obtain sufficient market information. This enables rational judgments to be made concerning the asset's functionality, utility and transaction price. The open market assumption is based on the fact that assets can be traded openly in the market.

3. Continuous use of assets assumption: The continuous use of assets assumption refers to the valuation which is carried out based on the continued use of the appraised assets in their current purpose, utilization manner, scale, frequency, environment and other circumstances.

4. Assumption of continuing use at a different location: The assumption of continuing use at a different location refers to the case when the appraised asset will continue to be used following a change of location or space and being transferred to another location or space after change in property rights or related asset business.

5. Seller's As-Is disposal assumption: The seller's as-is disposal assumption assumes that, during the transaction process, the buyer bears other associated costs including equipment relocation and site restoration expenses, while the seller incurs no transaction-related costs.

II. Special Assumptions

1. This valuation assumes that the external economic environment remains unchanged as at the Valuation Reference Date and that there are no significant changes in the country's prevailing macro-economy;

2. There is no material change in the socio-economic environment in which the enterprise operates, and in the policies implemented with respect to taxes and tax rates;

3. The assets subject to this valuation are determined based on its actual quantities as at the Valuation Reference Date, while the prevailing market prices of the relevant assets are determined according to effective prices as at the Valuation Reference Date;

4. This valuation assumes that the underlying information and financial information provided by the principal and the property right holder are true, accurate and complete;

5. The scope of valuation is strictly limited to the asset declaration forms provided by the principal and the property right holder, excluding consideration of any contingent asset and contingent liability which might exist beyond such lists provided by the principal and the property right holder;

6. The impact of inflation has not been taken into account in arriving at the parameter values measured under this valuation;

7. When the above conditions change, the valuation result is generally invalidated.

(III) VALUATION CONCLUSION

Accordingly, the total appraised value of the two A350 aircraft as of the Valuation Reference Date is RMB2,067,389,700.00, representing an appreciation rate of 0.06% over the book value of RMB2,066,199,547.82.
