"Further, the British assets of Tata Steel and Jaguar land Rover are not owned by Tata Sons. These are subsidiaries of Indian public listed companies of which Tata Sons is a promoter with a minority shareholding of not more than 30-35 per cent," it had said. Tata Sons also said that these firms were not party to the arbitration proceedings and so no award has been issued against them. The arbitral award is the result of a two-year tussle between the partners in their failed joint venture Tata Teleservices in which NTT Docomo of Japan holds 26 per cent stake which it had picked up in November 2008 for USD 2.7 billion or about Rs 12,770 crore at the then exchange rate.
