Tata Consultancy Services Ltd has won a $2.25-billion (Rs 14,411 crore) outsourcing contract from data and ratings measurement company Nielsen, Mint reported on Friday. It is the largest ever outsourcing contract bagged by an Indian information technology firm.

The two companies had first signed a deal worth $1.2 billion (Rs 7,684 crore) in 2008, PTI reported. The deal was supposed to be valid for 10 years.

Under the renewed contract, the terms of the deal have been extended for an additional five years and would expire on December 31, 2025. Nielsen also has three one-year renewal options, the company said in a regulatory filing to the United States Securities and Exchange Commission.

The software firm will provide Nielsen with professional services relating to information technology, business process outsourcing, client service knowledge process outsourcing, management sciences, analytics and financial planning.

The deal is a major achievement for Rajesh Gopinathan, who took over as Tata Consultancy’s chief executive officer in February after N Chandrasekaran was appointed the chairperson of Tata Sons Ltd, the group’s holding company.
