Docomo had invested $2.2 billion to purchase 26.5 percent stake in Tata Docomo in 2009. As per the deal, Docomo was supposed to get 50 percent of $2.2 billion or fair market price, whichever is higher, if the Japanese telecom giant decides to exit from Tata Docomo. In 2014 April, Docomo decided to exit from Tata Docomo due to growing losses.
Since Tata Sons could not rope in a buyer for the 26.5 percent after discussing with Telenor, MTS, etc. Docomo moved the London court of International Arbitration in January this year. Both Tata Sons and Docomo will try to solve the issue at the arbitration court.
