TCS has signaled its intention to buy Citigroup’s BPO arm, Citigroup Global Services with an offer of US$505 million offer for the India-based captive. In addition to the sale, TCS will also take over outsourcing services for Citi and its affiliates to the value of US$2.5 billion over a period of nine years.

The agreement builds upon the existing relationship between Citi and TCS whereby TCS provides application development, infrastructure support, help desk and other process outsourcing services to Citi.

Don Callahan, Chief Administrative Officer, Citi said: “This is a great transaction that benefits all parties – Citi, our customers, our employees and TCS. Our customers require access to increasingly complex processing solutions and this relationship will achieve a ‘best in class’ technology model that capitalises on both CGSL’s expertise in financial services and TCS’s expertise in process optimisation. TCS will offer CGSL stronger growth potential and superior continued services to Citi clients around the world. This transaction is expected to help reduce operating expenses related to business processing and will allow us to focus on our core financial services competencies.”

The acquisition will broaden TCS’s portfolio of end-to-end IT and BPO services in the global Banking and Financial Services (BFS) sector. TCS’s claims that its enhanced scale and expertise will provide service improvements to Citi and Citi’s customers.

The parties expect to close the transaction in the fourth quarter of 2008.
