NEWLY listed property developer Pearl Oriental Holdings has announced a 14.7 per cent increase in after-tax profit, to $103.76 million, in the first six months of the year, compared with $90.46 million previously. Basic earnings per share were 10.6 cents, while the interim dividend was five cents per share. Fully diluted earnings per share were 9.2 cents. The company has anticipated a large increase in profits in the second half because of the transactions of the pre-sale properties. The dividends payment would also be increased at that time, it said. The amount of the sales and pre-sales of commercial properties in the first half of the year exceeded $3.2 billion. These properties included two-thirds of the interests in Pearl Oriental Centre, Pearl Oriental House, Wellington Centre and Hua Hsia Building. Construction on those developments had progressed satisfactorily and work was expected to be completed by 1996 at the latest, it said. Regarding its hotel arm, the Pearl Seaview Hotel was now open for business with a high occupancy rate, the company said.
