Finance Cost Higher y-o-y due to increase in borrowing for ESL acquisition and increase in interest rates in line with the market rates. Other income Lower y-o-y on account of lower investment corpus and mark to market loss on investments partly offset by one time reclassification from other comprehensive income at Zinc India. Exceptional Items Includes previously recorded reversal of impairment in Oil & Gas business and reversal of charge relating to arbitration of a historical vendor claim pursuant to Supreme Court Order in Aluminium business. Taxes Tax rate for current quarter is 26%. The tax rate for the year is expected to be 30% as per earlier guidance. Profit After Taxes Lower y-o-y primarily on account of lower interest income
