Tata Sons' fortunes are dependent on TCS, in which it holds close to a 74 per cent stake and from which it received a dividend of Rs 11,402 crore. Other big companies in the group such as Tata Motors skipped paying dividends and Tata Steel's contribution fell to Rs 231 crore (see chart).
Only nine listed companies in India have made more net profit than Tata Sons in 2014-15. Apart from dividend income, Tata Sons earns a significant amount from the group companies for using the Tata brand name. The brand fees have been capped at Rs 75 crore since 2012-13.

During 2014-15, Tata Sons' cash and cash equivalents more than doubled to Rs 13,171 crore from Rs 5,980 crore. The higher cash balance was partly on account of a special dividend of Rs 5,800 crore received from TCS, said an analyst.
