Vedanta, formerly known as Sesa Sterlite, swung to a net loss for the quarter ended Mar. 31, 2015, due to huge impairment charge for goodwill. The company has reported a net loss of Rs.187.18 billion, or Rs.64.85 a share in the quarter, against a net profit of Rs.34.73 billion, or Rs.5.66 a share in the last year period.

Revenue during the quarter declined 14.80 percent to Rs. 178.04 billion from Rs. 208.94 billion in the previous year period.

Exceptional items included a one-time non-cash impairment charge of Rs. 199.56 billion largely relating to Cairn India acquisition goodwill (Rs 191.80 billion) and the Sri Lanka Block (Rs 5.05 billion) on account of a steep fall in crude oil prices, the company said.

Excluding the exceptional items, the profit from ordinary activities during the quarter was Rs. 17.87 billion compared with profit of Rs. 39.68 billion in the last year period.

Tom Albanese, CEO, Vedanta, said, 'Our Q4 results include an one-time non-cash impairment charge of acquisition goodwill, largely relating to the Oil & Gas business and the Sri Lanka Block on account of a steep fall in crude oil prices. This has no impact on the production or future earnings capacity of these assets.'

Shares of the company declined Rs 4.55, or 2.15%, to settle at Rs 207.15. The total volume of shares traded was 911,534 at the BSE (Wednesday).
