Vision Telecommunications plans to list its optical-networking arm this year on the Growth Enterprise Market (GEM) and Nasdaq market in the United States, according to the company's controlling shareholder. A feasibility study on floating Optilink Technologies was being carried out, said Grace Chan Foo kam-chu, who owns 80 per cent of Vision Telecommunications. Mrs Chan is also chairman of listed property company Soundwill Holdings, which on Sunday agreed to pay $82.11 million for a 20 per cent stake in Vision Telecommunications. Vision Telecommunications has a 70 per cent stake in Optilink, its only asset. Peking University owns the remaining stake. Optilink applies optical technology to bolster capacity at mainland telephone companies. Meanwhile, Mrs Chan said she would place 135 million of her Soundwill shares at 63 cents each and then subscribe to an equivalent number of new shares at the same price to raise funds to finance the purchase of the Vision Telecommunications stake. Soundwill's shares yesterday fell two cents to finish at 66 cents. Trading in the counter resumed yesterday after being suspended on March 9, pending the announcement of the Vision Telecommunications transaction. Winnie Chan Wai-yu, an Optilink director, said that the proceeds from the Vision Telecommunications-Soundwill transaction would be used to fund the company's expansion. Ms Chan, daughter of the Soundwill chairman, is also a director of Soundwill's information-technology arm, Soundwill Technology. Ms Chan said that Optilink was involved in contract negotiations with mainland companies worth more than 10 million yuan (about HK$9.35 million).
