High Tech Computer (HTC), the world\u2019s largest maker of mobile phones that use Microsoft software, will buy a controlling share in one of its customers, phone vendor Dopod (Cayman) Holding, HTC announced Sunday.The deal marks a shift in strategy for HTC, which until now has said it had no plans to sell phones under its own brand name. It has made them only under contract for companies such as Dopod. The controlling stake in Dopod moves HTC closer to having its own brand of phones on the market.HTC made trouble for itself by originally announcing it intended to spend "no more than US$150 million" to buy\u00a0more than\u00a0half of the shares in Dopod, which owns several subsidiaries including phone vendor Dopod International.But investors balked at the high price of the deal, and HTC backtracked by saying it valued Dopod at $150 million in total; therefore, a 60 percent stake should cost HTC about $90 million.Further souring investor views on the deal was a rumor that the chairman of HTC, Cher Wang, owned part of Dopod. An HTC spokeswoman said it wasn\u2019t true."Our chairman does not own any shares in Dopod," said Maggie Cheng, head of public relations at HTC. She said a final deal for Dopod has not yet been reached, but HTC expects to acquire between 50 percent and 100 percent of the handset maker by the end of this year.HTC shares were down 7 percent in early stock trading on Monday at 968 new Taiwan dollars\u00a0each (US$30.22).-Dan Nystedt, IDG News ServiceCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
