Cross-Harbour Tunnel yesterday unveiled a 50 per cent drop in attributable profit to $76.1 million for the six months to June 30, which it partly attributed to reduced traffic through the Cross-Harbour Tunnel. The company also took a $66 million share of losses from 37 per cent-held Western Harbour Tunnel. Turnover rose 3 per cent to $423 million from $409.5 million the previous year, while earnings per share fell to 40 cents from 79 cents. The company said it would cease to manage the Aberdeen Tunnel next month. The management contract has been awarded to another firm by the Government. It is also 'actively pursuing discussions with the Government' to extend its management contract for the Cross-Harbour Tunnel. However, the company warned shareholders at the last annual meeting to expect non-renewal of the contract. The company also said it would not make provisions for its listed investments, despite their market value being lower than their carrying value. 'The group intends to hold its investment portfolio for investment purposes and, accordingly, no further provision for permanent diminution in value . . . is considered necessary [now],' it said. Shareholders will receive a second-quarter dividend of 19 cents for a total interim dividend of 46 cents a share, down from last year's 54 cents a share interim payout.
