Quick on the heels of the news that Satyam, Wipro and Copal Partners have expressed interest in bidding for the Indian back office business of Lehman Brothers Holdings, top BPO firm Genpact, has also joined the race to acquire the Mumbai-based captive back-office unit for an undisclosed sum.

When contacted Genpact president & CEO Pramod Bhasin refrained from commenting and called the news speculative, according to a report published in the Economic Times. Company sources, however, confirmed that Genpact is eyeing Lehman’s captive operation that employs between 1,500 and 2,000 people. The buzz is equally strong among bulge bracket investment bankers close to Lehman and Genpact. Lehman Brothers too declined to comment.

Genpact had earlier evinced an interest to acquire companies with revenues of about $150-200 million. The company, which started catering to the domestic BPO market this year, said it is scouting for captives and niche companies in India. Only last year, it was in talks to acquire Citigroup’s captive operations in India, Citigroup Global Services (CGS).
