The administrators of Teddy Wang's estate are seeking to force his widow, Nina Wang, to repay a $4.5 billion loan she made to a company in which she had an interest. The news came as the Court of Appeal was asked to overturn Madam Justice Susan Kwan Shuk-hing's decision in May striking out the repayment claim in a petition brought by the administrators. Barrister Robert Hildyard, QC, for the administrators, said Ms Wang, chairwoman of the Chinachem Group, had mismanaged the affairs of Chime Corporation - a subsidiary of Chinachem in which the administrators have shares - by advancing an unsecured, interest-free loan of $4.5 billion to Chinachem Agencies. The loan was made with no fixed terms as to repayment and for no proper commercial purpose, the court heard. Ms Wang claimed she had a beneficial interest in Chinachem Agencies and that her husband did not. The court-appointed administrators, Tan Man-kou of Deloitte Touche Tohmatsu, and Brian Cheung Yat-ming of PricewaterhouseCoopers, are demanding a repayment of the loan plus interest to Chime Corporation. Other measures sought by the administrators against Ms Wang include an order to set aside the allotment of 15 million Chime B shares and the payment of dividends on the shares. Ms Wang was also said to have transferred into her own name 19,998 Chime A shares that belonged to her husband. Ms Wang's barrister, Robin Potts SC, argued that the administrators - who are also shareholders of Chime - were not entitled under company law to claim monetary compensation. Mr Justice Geoffrey Ma and Mr Justice William Stone reserved their decisions.
