The Group uses interest rate swap c

The Group uses interest rate swap contracts to hedge its interest rate risks, predominantly arising from financing activities. Under interest rate swap contracts, the Group agrees to exchange the difference between fixed and floating rate interest amounts calculated on agreed notional principal amounts. Such contracts enable the Group to mitigate the cash flow exposures on the variable rate debt and are accounted for as cash flow hedges. The fair value of interest rate swaps at the end of the reporting period is determined by discounting the future cash flows using the curves at the end of the reporting period and the credit risk inherent in the contract, and is disclosed below. The Group’s cash flow hedges settle on a monthly basis. The Group settles the difference between the fixed and floating interest rate payable/(receivable) under each cash flow hedge on a net basis.
