Tata Sons Pvt. Ltd. is the holding company of the Tata Group, headquartered in Mumbai. It owns the bulk of shareholding in the affiliate companies of Tata Group, as well as its land holdings across India, tea estates and steel plants. It derives its revenue from dividends from these companies, and owns the Tata trademark registered in India and several other countries.[5]
Tata Sons was established as a trading enterprise in 1917, and engaged primarily in the overseeing of Tata Group's profits and structuring them into the right direction,[6] before moving from conducting businesses directly to becoming the principal holding company of Tata Group.[7] About 66% of its equity capital is held by philanthropic trusts endowed by members of the Tata family. The biggest two of these trusts are the Sir Dorabji Tata Trust and Sir Ratan Tata Trust.[8]
