Shares of Golden Resorts Group, a Macau casino hotel investor, fell 2.25 per cent yesterday after the company scrapped its HK$147 million purchase of a stake in a Cambodian bookmaking business. Golden Resorts in May signed a memorandum of understanding to acquire a 49 per cent indirect interest in Cambo Six from the Phnom Penh-based firm's chairman and substantial shareholder, Wyman So Man-kit. Cambo Six operates 30 soccer betting outlets across Cambodia. Golden Resorts shares gained 40 per cent the day after news of the deal broke. But the firm announced late on Tuesday that all bets were off. 'The company is not in total agreement with the other shareholders of Cambo Six on the future operation arrangement of the business,' Golden Resorts said in a stock exchange filing. 'The board considers that the decision on not to proceed with the acquisition would serve the best interests of the shareholders.' Further details were not provided and the firm did not identify the shareholders involved in the disagreement. When Golden Resorts announced last month the terms of the formal acquisition, the selling party was identified not as Mr So but as Nancy Chau Dinh Nhi, a Cambo Six director. The company did not explain the switch. Golden Resorts management in recent months has emphasised seeking gaming-related investments in Southeast Asia as a way to hedge bets against increasing competition and rising cost barriers for new projects in Macau. In April, it raised HK$435.6 million in share placement to fund potential new investments. Cambo Six appeared to be a rare target due to its unique position as the only licensed soccer betting firm in a country that lacks specific industry legislation and where underground bookmakers and gambling halls are numerous. The stock fell 2.25 per cent to close at 87 HK cents yesterday. They have risen 172 per cent so far this year.
