In a statement, Tata Sons said it has reached an agreement with NTT Docomo "on a joint approach to enable enforcement" of June 22, 2016, compensation award granted by the London Court of International Arbitration (LCIA) in favour of the Japanese company.
"As a gesture of good faith and in accordance with the Tata Group's long-standing record of adherence to contractual commitments that it has always enjoyed both in India and abroad, the board of Tata Sons has decided to withdraw its objections to the enforcement of the award in India," it said.
Tata Sons said that as per the agreement, the settlement terms, if approved, "clear the way for the USD 1.18 billion already deposited by Tata Sons with the court to be paid to Docomo and would allow Docomo to transfer its shares in Tata Teleservices Ltd".
NTT Docomo, in November 2008, acquired 26.5 per cent stake in Tata Teleservices for about Rs 12,740 crore (at Rs 117 per share), offering services under the Tata Docomo brand.
