As at the date of this announcement, the Company held 13,707,044 ordinary shares in treasury. The impact of the repurchases of the ordinary shares on the financial position of the Company is immaterial, as the repurchases were funded out of the Company’s available cash resources. OPINION OF THE BOARD The Board has considered the effect of the repurchases and is of the opinion that, for a period of 12 months following the date of this announcement: - the Company and its subsidiaries (“the Group”) will be able, in the ordinary course of business, to repay their debts; - the consolidated assets of the Company and the Group will be in excess of the consolidated liabilities of the Company and the Group; - the Company’s and the Group’s share capital and reserves will be adequate for the ordinary business purposes of the Company and the Group; and - the Company and the Group will have sufficient working capital for ordinary business purposes.
