(d) Valuation technique to determine fair value
the following methods and assumptions were used to estimate the fair values of financial instruments:
(i) the management assessed that fair value of cash and cash equivalents, trade receivables, trade payables, bank overdrafts and
other current financial assets and liabilities approximate their carrying amounts largely due to the short-term maturities of
these instruments.
(ii) the fair values of the equity investment which are quoted, are derived from quoted market prices in active markets. the
Investments measured at fair value and falling under fair value hierarchy level 3 are valued on the basis of valuation reports
provided by external valuers with the exception of certain investments, where cost has been considered as an appropriate
estimate of fair value because of a wide range of possible fair value measurements and cost represents the best estimate of fair
values within that range.
(iii) the fair values of investments in mutual fund units is based on the net asset value (‘naV’) as stated by the issuers of these
mutual fund units in the published statements as at Balance Sheet date. naV represents the price at which the issuer will issue
further units of mutual fund and the price at which issuers will redeem such units from the investors.
(iv) the group enters into derivative financial instruments with various counterparties, principally financial institutions with
investment grade credit ratings. the fair value of derivative financial instruments is based on observable market inputs including
currency spot and forward rate, yield curves, currency volatility, credit quality of counterparties, interest rate curves and forward
rate curves of the underlying commodity etc. and use of appropriate valuation models.
(v) the fair value of non-current borrowings carrying floating-rate of interest is not impacted due to interest rate changes, and will
not be significantly different from their carrying amounts as there is no significant change in the underlying credit risk of the
group (since the date of inception of the loans).
(vi) the fair values of the 10% unsecured redeemable non-convertible debenture (included in current maturities of non-current
borrowings) are derived from quoted market prices. the group has no other non-current borrowings with fixed-rate of interest.

(e) Financial risk management objectives
the group is exposed to market risk (including currency risk, interest rate risk and other price risk), credit risk and liquidity risk. the
group’s risk management strategies focus on the un-predictability of these elements and seek to minimise the potential adverse
effects on its financial performance. the Board of directors/Committee of Board of the respective operating entities approve the risk
management policies. the implementation of these policies is the responsibility of the operating entities. the Board of directors/
Committee of Board of the respective operating entities periodically review the exposures to financial risks, and the measures taken
for risk mitigation and the results thereof.

all hedging activities for risk management purposes are carried out by specialist teams that have the appropriate skills, experience
and supervision. the group’s policy is not to trade in derivatives for speculative purposes.
