Acer Inc says it plans to spin off 21 of its business units into partially-owned quoted subsidiaries by the start of the 21st century: it plans to keep its core technology operations in Taiwan, and spin off its regional sales, marketing, product integration and service operations around the world, retaining a minority of the equity – as little as 19% in some cases – in each business unit, and selling the rest to local investors; the first two flotations will be late this year.
