The following tables show the valuation techniques used in measuring fair values at March 31, 2019 and March 31, 2020 as well as the significant unobservable inputs used.

			Inter-relationship between
		Significant	significant unobservable
		unobservable	inputs and fair value
Type	Valuation technique	inputs	measurement
A. Financial Instruments measured at fair value:
Warrants	Black - Scholes model: The valuation model considers the share price on measurement date, expected term of the instrument, risk free rate (based on government bonds), expected volatility and expected dividend rate.	Expected term: 1.66 years (PY: 2.16 years) Risk free rate: 0.22% (PY 2.24%)	The estimated fair value would increase (decrease) if : ·  the expected term were higher (lower) ·  the risk free rate were higher (lower)
Quoted Warrants	Fair market value	—	—
Liability for business acquisition (refer to Note 43)	Actual as per the terms of share purchase agreement	Adjusted earning of acquired entity	—
B. Financial Instruments for which fair value is disclosed:
Borrowings	Discounted cash flows	Prevailing interest rate in market, future payouts.	—
