The Wei family, best known for controlling Hong Kong-listed noodle maker Tingyi Cayman Islands Holding Corp (>> Tingyi (Cayman Islands) Holding Corp.), is diversifying into telecoms and media. Its new 4G wireless services firm, Taiwan Star, will begin services this week.

The Wei family, which is led by Wei Ying-chiao, will be making the investment in CNS in a personal capacity and will also ask other Taiwanese businessmen to invest, the sources said.

"We won this deal because we worked very hard on this for a long time," said a person close to the Wei family, asking not to be identified as the deal has not been announced officially.

"This is not final yet. We still need the blessing of Taiwan's regulators."

If successful, the CNS purchase will rank as Taiwan's sixth-biggest M&A deal, matching United Arab Emirates state-owned International Petroleum Investment Corp's acquisition of a 20 percent stake in Kuokwang Petrochemical Co Ltd for $2.4 billion in 2005, according to Thomson Reuters data.

MBK owns 60 percent of CNS, which has about 1.2 million cable TV subscribers. CNS competes with Kbro and several other small rivals.

The person said the Wei family planned to hold more than 50 percent of the company and that businessmen who may be tapped to invest include H.T. Tsai, the chairman of Cathay Financial Holding Co (>> Cathay Financial Holding Co., Ltd.) and T.C. Gou, the chairman of electronics parts firm Cheng Uei Precision Industry Co Ltd (>> Cheng Uei Precision Industry Co., Ltd.).

The Wei family beat rival bidders Hon Hai Precision Industry Co (>> Hon Hai Precision Industry Co., Ltd.), a key Apple Inc (>> Apple Inc.) supplier, and Far EasTone Telecommunications (>> Far EasTone Telecommunications Co., Ltd.), the person said.

A representative for the Wei family's Ting Hsin International Group in Taipei was not immediately available for comment. MBK, which made the investment in 2007, did not respond to an email seeking comment.

This is the Asia-focused buyout firm's second attempt to sell CNS after regulatory delays helped cause the collapse of a previous deal with a group led by Want Want China Holdings (>> Want Want China Holdings Ltd.), a rice cake maker and owner of a Taiwanese media conglomerate.

A banker working on the deal said the Wei family's personal investment in the acquisition and lack of other media businesses is expected help smooth regulatory clearance of the deal. At the closure of the deal, CNS would have debt of about $1 billion, the person added.

Morgan Stanley (>> Morgan Stanley) is advising MBK, while UBS AG (>> UBS AG) is advising the Wei family. Morgan Stanley and UBS declined to comment.
