Cheung Kong (Holdings) plans to spin off at least three Internet and telecommunications concerns this year, according to a source close to the firm. The largest contributor to exceptional profit could come from a spin-off of Portnportals.com, owned by a subsidiary of 49.9 per cent-owned Hutchison Whampoa, the source said. The spinning off of Portnpor tals.com, a logistics portal for shippers developed by Hongkong International Terminals, could come as soon as next week, he said. The portal's value has been estimated in the range of $30 billion to $130 billion. Another likely spin-off is Hutchison's 50 per cent-owned fixed-line network operator, Hutchison-Global Crossing, the source said. Executives at United States-based Global Crossing, which owns 50 per cent of the company, have said a listing plan could be finalised during the second half of the year. Hutchison sold the 50 per cent stake in the fixed-line network operator to Global Crossing for US$400 million in December. Another listing candidate is iBusiness, in which Cheung Kong has a 62 per cent attributable stake, the source said. However, Victor Li Tzar-kuoi, Cheung Kong's managing director, has indicated an iBusiness listing would probably come after the listings of i21, a direct investment of the subsidiary. IBusiness has a 62.5 per cent interest in i21, an application venture with Excel Technology International. 'Our investments will make up a very long list,' Mr Li said.
