The disposal follows the sale of a 26pc interest to a mainland company A co-founder of TPV Technology has sold off all but his last remaining shares in the No2 maker of personal-computer monitors. Non-executive director Stanley Pen Fang-jen sold to institutional investors 15.58 per cent of the Hong Kong and Singapore-listed company in a HK$748.33 million deal arranged by HSBC. The disposal follows Mr Pen's sale of a 26.36 per cent stake to mainland panel-display maker BOE Technology Group for HK$1.05 billion last month. BOE, which has become TPV's single largest shareholder as a result of the acquisition, said it did not know who bought the shares from Mr Pen yesterday. 'There is no way for us to tell how we can co-operate with the new shareholders, as they are not known to us,' BOE senior vice-president Chen Yanshun said. TPV and BOE are long-time manufacturing partners. In February, the mainland company bought a thin-film transistor liquid-crystal display (TFT-LCD) plant from South Korea's Hynix Semiconductor for US$380 million. BOE is building a fifth-generation TFT-LCD plant in Beijing, which will cost US$1.2 billion, and will probably sell output from the plant to TPV for use in its computer monitors. A shortage of LCD panels had constrained TPV's sales growth in the first quarter. In the latest share disposal, Mr Pen will unload 210.5 million shares for HK$3.55 each - a 10 per cent discount to their last traded price of $3.95 on Wednesday. The company's shares were suspended yesterday and were expected to resume trading today. The two equity disposals will reduce Mr Pen's stake to just 0.4 per cent of TPV's issued share capital. Analysts said his disposals would not materially affect the company's fundamentals as Mr Pen was not involved in managing the firm. But ABN Amro Asia director Eddie Lau said the stake sale could put pressure on TPV's shares because of its size.
