Employees of Nina Wang Kung Yu-sum at the Chinachem Group yesterday placed a death notice for their late boss in the name of Teddy Wang Teh-huei - her husband who was declared dead in September, 1999, nine years after his disappearance. An obituary that ran alongside the notice, signed off by staff of the Chinachem Group, also revealed that Wang, the richest woman in Asia, had been fighting a battle against cancer since early 2004. The obituary was the first official confirmation of the cause of Nina Wang's death. The death notice, carried by some Chinese-language newspapers today, announced the loss of 'Deceased wife Madam Wang Kung Yu-sum' with Teddy Wang's name at the bottom of the notice. Wang was snatched from his car in 1990 and held captive at sea. His wife paid a ransom of $260 million for his release. According to one of the kidnappers, the tycoon was thrown overboard into the South China Sea as the boat was chased by mainland marine police. Nevertheless, Nina Wang had maintained over the years that her husband was still alive. The notice said a vigil would be held at the Hong Kong Funeral Home in North Point from 4pm onwards on Tuesday, followed by a funeral at 11am the next day. Condolence contributions should be donated to the Chinachem Charitable Foundation Limited, according to the notice. 'Chairwoman Yu-sum had been diagnosed as having cancer in a health check in early 2004. She immediately went to an affiliated hospital of the Harvard Medical School to seek treatment. Unfortunately, she could not find a cure for her illness despite undergoing treatment by many world-renowned doctors and with the most advanced medicine,' the obituary read. It also praised her for her dedication to the company by working up until the last moments of her life. Meanwhile, the future of her estate, with a net worth of HK$32.7 billion according to Forbes magazine's 2007 rich list, still remains unknown. The sole beneficiary to the fortune is expected to meet lawyer Jonathan Midgley today to confirm details of the estate. The meeting follows intense speculation over the identity of the beneficiary, which Mr Midgley said would be made public after the funeral. While Nina Wang had stated her desire for a small funeral, her wish seems unlikely to be granted given the composition of the organising committee. Legco president Rita Fan Hsu Lai-tai, Hong Kong Exchanges and Clearing chairman Ronald Arculli, and Executive Council convenor and Hong Kong member of the standing committee of the Chinese People's Political Consultative Conference Leung Chun-ying have confirmed they are on the committee to organise a Catholic funeral. Liberal Party leader and new head of the Tourism Board James Tien Pei-chun and Sino Land chairman Robert Ng Chee Siong will also play a part in the organising.
