Malvinder Singh, currently the Chairman of Fortis Healthcare, and family including his brother Shivinder Singh, had sold their entire stake of about 35 per cent in Ranbaxy for $2.4 billion in 2008 to Daiichi Sankyo.
However, in 2013, the Japanese pharmaceutical major had filed an arbitration case in Singapore accusing the Indian promoters of concealment and misrepresentation of facts after Ranbaxy paid $500 million to the US Department of Justice as settlement for misrepresenting facts.

After buying out the erstwhile promoters, Daiichi spent a total of around Rs 22,000 crore to gain a majority stake in Ranbaxy. Later on, the Japanese firm exited Ranbaxy following a $4.2 billion merger deal between Sun Pharma and Ranbaxy.
Last April, Daiichi Sankyo sold its entire stake of around 9 per cent in Sun Pharmaceutical Industries for over Rs 20,420 crore, which it received after merger of Ranbaxy in the Indian firm, ending its seven years of tumultuous experience in the country.
