APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

This Appendix serves as an explanatory statement, as required by the Listing Rules, to provide requisite information to you for your consideration of the Repurchase Mandate.

1. LISTING RULES RELATING TO THE REPURCHASE OF SHARES

The Listing Rules permit companies whose primary listing is on the Main Board of the Stock Exchange to repurchase their shares on the Main Board of the Stock Exchange subject to certain restrictions. Among such restrictions, the Listing Rules provide that the shares of such company must be fully paid up and all repurchase of shares by such a company must be approved in advance by an ordinary resolution of the shareholders, either by way of a general mandate or by specific approval of a specific transaction.

2. SHARE CAPITAL

As at the Latest Practicable Date, the Company had 6,406,008,147 Shares in issue. Subject to the passing of the resolution for the grant of the Repurchase Mandate (resolution numbered 5 as set out in the notice convening the Annual General Meeting contained in this circular), and assuming that no new Shares are issued or repurchased by the Company prior to the Annual General Meeting, the Company will be allowed under the Repurchase Mandate to repurchase a maximum of 640,600,814 Shares.

3. REASONS FOR THE REPURCHASE

The Directors believe that it is in the best interests of the Company and its Shareholders as a whole for the Directors to have general authority from the Shareholders to enable the Company to repurchase Shares in the market. Such repurchases may, depending on market conditions and funding arrangements of the Company at the time, lead to an enhancement of the net asset value per Share and/or earnings per Share and will only be made if the Directors believe that such repurchases will benefit the Company and its Shareholders as a whole.

4. FUNDING OF REPURCHASES

Repurchases must be paid out of funds legally available for the purpose and in accordance with the Articles, the Companies Law, other applicable laws of the Cayman Islands and the Listing Rules. A listed company is prohibited from repurchasing its own shares on the Stock Exchange for a consideration other than cash or for settlement otherwise than in accordance with the trading rules of the Stock Exchange. Under the Cayman Islands law, any repurchases by the Company may only be made out of profits or share premium account of the Company or out of the proceeds of a fresh issue of shares made for the purpose of repurchase or, if authorised by the Articles and subject to the Companies Law, out of capital. Any premium payable on a purchase over the par value of the shares to be repurchased must be provided for out of profits or the share premium account of the Company or, if authorised by the Articles and subject to the Companies Law, out of capital.

- I-1 -

APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

5. MATERIAL ADVERSE IMPACT OF REPURCHASES

On the basis of the current financial position of the Company and taking into account the current working capital position of the Company, the Directors consider that, if the Repurchase Mandate was to be exercised in full, it might have a material adverse effect on the working capital and/or the gearing position of the Company as compared with the position as at 31 December 2020, being the date to which the last audited accounts of the Company were made up. However, the Directors do not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing position of the Company which in the opinion of the Directors are from time to time appropriate for the Company.

6. SHARE PRICES

The highest and lowest prices at which the Shares have been traded on the Stock Exchange during each of the following months were as follows:

	Highest	Lowest
	HK$	HK$
2020
April	0.187	0.135
May	0.168	0.135
June	0.147	0.129
July	0.144	0.123
August	0.140	0.110
September	0.134	0.110
October	0.140	0.116
November	0.122	0.095
December	0.123	0.113
2021
January	0.125	0.099
February	0.122	0.102
March	0.109	0.100
April (Up to the Latest Practicable Date)	0.100	0.098

7. UNDERTAKINGS AND DISCLOSURE OF INTERESTS

The Directors have undertaken to the Stock Exchange that they will exercise the power of the Company to make repurchases under the Repurchase Mandate in accordance with the Listing Rules and the applicable laws of the Cayman Islands and in accordance with the regulations set out in the memorandum of association of the Company and the Articles. None of the Directors nor, to the best of their knowledge having made all reasonable enquiries, any of their close associates (as defined in the Listing Rules) have any present intention to sell any Shares to the

- I-2 -

APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

Company or its subsidiaries under the Repurchase Mandate, in the event that the Repurchase Mandate is approved at the Annual General Meeting by the Shareholders.

8. CORE CONNECTED PERSONS

No core connected person (as defined in the Listing Rules) of the Company has notified the Company that he/she/it has a present intention to sell any Shares to the Company and no such person has undertaken not to sell any Shares held by him/her/it to the Company, in the event that the Repurchase Mandate is approved at the Annual General Meeting by the Shareholders.

9. THE TAKEOVERS CODE AND MINIMUM PUBLIC HOLDING

If a Shareholder's proportionate interest in the voting rights of the Company increases on the Company exercising its powers to repurchase Shares pursuant to the Repurchase Mandate, such increase will be treated as an acquisition for the purpose of the Takeovers Code. Accordingly, a Shareholder or a group of Shareholders acting in concert (as defined in the Takeover Code) could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

As at the Latest Practicable Date, to the best of the knowledge and belief of the Directors, the following Shareholders were interested in more than 10% of the Shares then in issue:

		Percentage
		Holding
Name	Number of Shares	(Approximately)
Automatic Result Limited	1,846,832,542 (Note 1)	28.82%
HeungKong Securities Limited	865,040,000	13.50%
Overseas Capital Assets Limited	657,180,000 (Note 2)	10.26%

Notes:

1. Automatic Result Limited is wholly owned by MJKPC Holdings Limited, which is a family trust of which Mr. Kingsley Leung, an executive Director is one of the discretionary objects.
2. Based on the individual substantial shareholder notice of Overseas Capital Assets Limited filed on 19 June 2014, Overseas Capital Assets Limited held 657,180,000 Shares and was wholly owned by He Rufeng.

- I-3 -

APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

In the event the Directors exercise in full the power to repurchase Shares in accordance with the Repurchase Mandate, the total interests of the above shareholders in the issued shares of the Company would be increased. Should the Directors intend to exercise the Repurchase Mandate to the extent that an obligation on the part of Automatic Result Limited to make a general offer for the Shares under the Takeovers Code may arise, the Company will apply to the Securities and Futures Commission for a waiver as and when appropriate.

	Percentage
	holding
Name	(Approximately)
Automatic Result Limited	32.00%
HeungKong Securities Limited	15.00%
Overseas Capital Assets Limited	11.40%

The Directors have no intention to exercise the Repurchase Mandate to such an extent that will result in the number of Shares in the hands of public falling below the prescribed minimum percentage of 25%.

10. SHARES REPURCHASE MADE BY THE COMPANY

No repurchase of Shares has been made by the Company (whether on the Stock Exchange or otherwise) during the six months preceding the Latest Practicable Date.
