Tata Consultancy Services acquired Citigroup's India based outsourcig unit Citigroup Global Services for $505 millon in an all cash deal. With that deal TCS alo got a $2.5 billion contract to provide process outsourcing services, application development and infrastructure support to Citigroup and its affiliates over 9 and half years. This is notable because the Citi contract is the biggest ever for an Indian company, as previously Indian companies have operated with smaller scale deals lasting 2-3 years and worth $50 to $200 million. In October 2007 TCS signed a 10 year $1.2 billion contract with Dutch group Nielsen. What this does is enhance TCS capabilities and expertise to go head to head with companies like IBM and EDS. The Citi acquisistion adds 12,000 employees and $280 million in revenues to TCS. TCS had 111,000 employees before the Citi Global Services acquisition and this expansion will enable it to compete more effectively with IBM and EDS/Hewlett Packard.
