CHINA Assets, the company at the centre of a bitter row with Regent Fund Management, will make an official announcement tomorrow in an attempt to douse investors' concerns about Regent's sale of its stake in the company. Regent and China Assets remain at loggerheads, with both sides arguing about how much money Regent made from the sale of its 10.1 per cent stake in the company. Regent claimed it made a 30 per cent return while China Assets insisted the maximum return was only 10 per cent. Herbert Hui, head of the stock exchange's listing division, said he was concerned investors were confused by the differing claims. 'We are looking very closely at the situation to see if the market needs more information to be disclosed. If we find there is, we will have no hesitation in asking for it,' he said. He said the exchange had not insisted on the official announcement. Regent managing director Peter Everington dismissed China Assets' claims as inaccurate and said its calculations were flawed. 'We sold at a premium to the market at a level above Friday's close of $3.775,' he said. 'You can give it any name you want, but it is a 30 per cent profit.' Lao Yuanyi, executive vice president of China Venturetech Investment Corp, which has a controlling interest in China Assets, said it had 'soundly defeated' Regent in its 'extended battle for the company'. He estimated Regent paid between $3.20 and $3.30 each for its 7.5 million shares and hinted they were sold below Friday's closing price. He said this resulted in a profit of approximately $3 million, or about 10 per cent of Regent's investment once its expenses had been taken into account. 'Considering the risks Regent took, not to mention the brokerage interest and legal expenses, it does not look like it was worth the effort,' he said. If Regent paid $3.25 per share, its investment totalled $24,375,000. Supposing Regent sold the shares at a two per cent premium to the market, it would have netted $28,878,750. This represents a total return of 15.6 per cent, excluding expenses. This indicates Regent either paid considerably less than the $3.20 to $3.30 estimated by China Venturetech or sold at a higher premium to Friday's closing price to have generated a 30 per cent return. Mr Everington said the exact sale price was confidential. Representatives for China Assets said the company was inspecting closely certain trades in the company's shares and would be making an announcement once the investigation had been completed. Regent attempted to have China Assets liquidated, alleging mismanagement, which resulted in its share price trading at a 45 per cent discount to net asset value. It claimed support from between 20 and 30 per cent of China Assets shareholders. Mr Lao said: 'I cannot help but wonder out loud 'Did Regent ever really have the support of 20 per cent of China Assets' shareholders?'' Mr Everington said: 'People may say we are the champions of the small shareholders but we are paid by our clients to make money and that is what we did.'
