Medium-sized developer Ryoden Development's net profit fell 93.29 per cent to $11.52 million for the six months to June 30 from $171.69 million in the first half of last year. An interest cost rise and drop in property development sales income affected the results, the firm said. Earnings per share were one cent, down from 16.5 cents previously. No interim dividend was recommended. Turnover fell 56.3 per cent year on year to $255.79 million. Deputy chairman and managing director Raymond Hu Liang-ming said Ryoden would review the value of its property portfolio by the end of the financial year to determine whether any loss provisions would be required.
