Asustek Computer, the world's largest producer of computer motherboards, hopes to increase its revenue to $15.65 billion this year as it increases its base of contract manufacturing customers and sells more own-brand products."We met our goal last year. Let's try to increase our revenue to NT$500 billion this year," said Jonney Shih, the chairman of Asustek, at a special company celebration ahead of the Lunar New Year holiday on Monday.That would mark a substantial increase from the company's revenue last year, NT$355.8 billion, which was up 38% over the NT$256.9 billion it took in the previous year.The company, which contract manufactures notebook computers for Apple Computer, in addition to game consoles and other products for other companies, did not set the NT$500 billion as a strict financial target, a company spokesman explained, but just a target to create enthusiasm among employees.Asustek's main business is motherboards, the circuit board inside a PC that holds and connects most of its vital chips and components. The company also sells products under its own brand, Asus, such as laptops and mobile phones. Last December, the company also unveiled its first own-brand LCD-TVs.
