In contrast, pre-royalty pre-tax profits have grown at a compounded annual growth rate (CAGR) of 9.6 per cent and net sales have grown by 8.7 per cent.
In 2015-16, aggregate royalty payments of 32 MNCs in the BSE 500 aggregated Rs 7,100 crore, up from Rs 6,300 crore in 2014-15.

"Companies must provide greater clarity regarding the basis on which royalty is paid out, given that it has outpaced both sales and profits in the past five years," IiAS said.
IiAS believes that the parent company needs to be compensated for brand and technical know-how. However, such payments need to be pegged at an appropriate level.
According to IiAS, an over 7 per cent lowering of margins driven by royalty alone is significant, and deprives investors of the earning per share (EPS) upside of investing in a stronger business or brand proposition.
