In accordance with the relevant regulations in the PRC, a 10% appropriation to the statutory general reserve based on the net income reported in the PRC financial statements is required until the balance reaches 50% of the authorized share capital of Yuchai and its subsidiaries. Statutory general reserve can be used to make good previous years’ losses, if any, and may be converted into share capital by the issue of new shares to shareholders in proportion to their existing shareholdings, or by increasing the par value of the shares currently held by them, provided that the reserve balance after such issue is not less than 25% of the authorized share capital.

(ii)

General surplus reserve is appropriated in accordance with Yuchai’s Articles and resolution of the board of directors. General surplus reserve may be used to offset accumulated losses or increase the registered capital.

Capital reserves consist of reserve resulted from (i) a capital transaction in 2015, (ii) the put option granted to the non-controlling interests of Yuchai’s subsidiary in 2022 and 2023 (further details are given in Note 29) and (iii) conversion of a subsidiary into a joint stock limited company represents the excess of net assets over the registered capital of the joint stock limited company as at date of conversion.
