WNS also plans to have a workforce of 10,000 by the end of March next year. It is already building a new campus in Gurgaon that can accommodate up to 2,500 professionals. Its current strength is 8,500.

WNS, the former captive BPO unit of British Airways acquired Arizona based Trinity Partners, a provider of BPO and IT services. This will enable the company to bag a minimum $60 million contract spread over five years straightaway with First Magnus Financial Corporation, Zubin Dubash, group CFO, WNS said.

"This acquisition positions WNS Trinity Mortgage Services, which will be a separate vertical, as a leading provider of BPO services in the mortgage industry," WNS said.

Trinity Partners', a profitable company, with 500 professionals and clients are now part of WNS Global. WNS Global, had a revenue of $165 million in 2004-05 and on that basis it was ranked as the number one BPO company by Nasscom.

WNS which has majority shareholding with private equity investor Warburg Pincus, has already made two acquisitions in the healthcare and insurance verticals. British Airways still holds 14 per cent equity in the company.

Replying to a query, if Warburg Pincus would want to exit, he said there are different ways to do it and IPO is one of them. "But at present nothing is on the agenda".
