Notes

(1)

The Group has not recognised DTA in absence of reasonable certainty towards its realisation. The net amount for 94B allowances for March 31, 2026 includes a credit of INR 1,922 representing a previously unrecognised DTA which the Group is now reasonably certain of realisation.

(2)

The amount is net off by INR Nil (March 31, 2025: INR 2,030, March 31, 2024: INR 1,064) that represents previously unrecognised DTA which was recognised in the current year.

(3)

The amount for March 31, 2026 includes a one time charge of INR 693 in few of the subsidiaries on account of their decision to move to the alternate lower tax regime and surrender future claim of tax holiday.
