RECENT action by the US Government and the Business Software Alliance (BSA) against software pirates in Asia is having a positive effect on the revenue of regional computer products distributors. And the rapid price cuts in computer products seen during the past two years have also contributed greatly to the success of such companies, according to SiS International, which distributes computer hardware and software in Asia. SiS International this week announced record sales and earnings, with its net profit rising to $29 million for last year, 153 per cent up on the 1991 figure. With turnover up from $104 million to $397 million, SiS is linking its success to that of anti-piracy efforts in the region. ''We opened an office in Taiwan in May last year, and since then we have seen a steady rise in sales of software, closely connected to anti-piracy action initiated against Taiwan by the BSA and the US Government,'' said Mr Lim Kia Hong, vice-president ofSIS International Holdings. Taiwan and South Korea were recently named the main hotbeds of software piracy by the US Government when it added the names of the two nations to its priority watch list under Special 301 provisions of the US Trade Act. ''Since so many governments in the region have been forced to pay attention to eradicating software piracy, our sales of the original products have risen considerably,'' Mr Lim said. In addition to action taken by the US against Thailand (which reportedly costs the US software industry US$49 million annually), China and the Philippines (said to have cost software developers up to US$250 million), the BSA has also been targeting against the illegal trade in computer products. Singapore, where SiS was born, came under attack from the BSA two weeks ago after representatives of the group smashed a pirate software manufacturing and mail-order ring in the city state. According to Mr Lim, however, the recent successes of anti-piracy operations in the region have not been the only aids to computer products distributors. ''During the past two years, the price of computers has dropped dramatically, with personal computer prices nearly halving,'' he said. ''This has meant that manufacturers have had to cut operating costs to maintain profits, and one of the main ways in which companies such as Compaq, Hewlett-Packard and IBM have been handling this problem is by appointing distributors.'' In the past, he said, computer vendors would have sold their products direct to dealers or end-users. This had created a need for many marketing and product support staff. Now, however, they were cutting back on such staff and relying on the marketing and technical expertise of product distributors. In Taiwan alone, SiS has been signed up as a distributor by vendors such as Central Point Software, WordPerfect Corp, Micrografx, Travelling Software, Aldus, Novell, Hewlett-Packard, Trend Micro Devices, Software Publishing Corp and, most recently, US personal computer giant Compaq.
