The company had reported operating loss of Rs. 4,883.5 crore (NOK 4978 million) for the same period a year ago.
"The findings are a testimony to the fact that Uninor is gaining momentum in India even with a limited number of circles they are present in. With break-even expected in other circles this year, the India picture is quite encouraging for the company," Uninor said in a statement.
The revenue of the company during the reported quarter declined by 13.46 percent at about Rs. 795.23 crore from Rs. 918.94 crore posted in the corresponding period in 2011.
In February 2012, Supreme Court cancelled all 22 licences of Uninor in the 2G case and the company was required to win spectrum in the November 2012 auction to continue its services.
At the time of cancellation of its licences, Uninor had its operations in 13 circles and it could win spectrum only in six circles for about Rs. 4,018 crore in the last auction.
In the fourth quarter, Uninor had to incur other expenses of Rs. 114.8 crore (NOK 117 million) mainly related to exit costs for the two circles West Bengal and Kolkata where it was not able to secure spectrum in November 2012 auction to continue operations. This also included an adjustment of the scale-down costs recorded in the third quarter.
For the year ended December 2012, the company reported operating loss of Rs. 6,170.4 crore (NOK 6,283 million). The company has reported operating loss of Rs. 8,361 crore (NOK 8,514 million) for the year 2011.
The annual income of Uninor increased by 23 percent at approx Rs. 3,650.2 crore (NOK 3716 million) for financial year ended December 2012 compared to Rs. 2,965.5 crore the company reported for FY 2011.
