(Adds detail and background.) By Patricia Kowsmann Of DOW JONES NEWSWIRES LONDON (Dow Jones)--TPG Inc. is back in the running for Royal Bank of Scotland Group PLC's (RBS) Global Merchant Services payments-processing unit after it agreed to tie up with buyout firm Clayton, Dubilier & Rice, a person familiar with the situation said Wednesday. The consortium is now competing with Advent International and Bain Capital, which also have tied up for the deal, valued at up to GBP2.5 billion. Earlier this week, people familiar with the matter said that TPG was dropping out of the race because it decided not to join forces with Clayton, Dubilier. RBS had been pushing for a combined bid, given the complexity and size of the unit. The two firms, however, continued discussions, according to another person familiar with the situation. Global Merchant Services' biggest asset is RBS Worldpay, which processes credit-card payments in 40 different countries. The auction, which is being run by UBS, initially attracted numerous offers from private equity firms, which can use the company's stable cash stream to pay interest on loans taken out to fund the acquisition. Once RBS picks a bidder, it will enter into exclusivity talks. A deal is expected to close in the third quarter. The RBS unit is being sold by the 83%-government owned bank as part of a disposal program forced on it after being bailed out by the state. -By Patricia Kowsmann, Dow Jones Newswires.
