Uninor, the Indian division of Norwegian telecommunications group Telenor, suffered an operating loss of Rs 512 crore (NOK 536 million) in the three months to September 30, 2012.

The operating loss is quite big, but it is nearly half of operating loss of Rs 1,037 crore that the company had reported for the corresponding period of previous year.

Accumulated losses of the Telenor's Indian arm stood at Rs 13,300 crore as of third quarter of 2012.

Revenues jumped 3 per cent during the reported period, from Rs 801 crore to Rs 825 crore.

Uninor's was among the telecommunications firms whose all licences were cancelled by Supreme Court of India in February. The company participated in recent 2G spectrum auction via Telewings and won back spectrum for six circles, viz. UP East, UP West, Bihar, Gujarat, Maharashtra and Andhra Pradesh, , for nearly Rs 4,018 crore.

The company's existing licences are valid only up to18th of January, 2013, after which the company's all assets and business will get transferred to new entity Telewings Communications.

Telenor owns nearly 74 per cent stake in Telewings Communications.
