On whether the evaluation exercise would be conducted by the DoT or the Comptroller and Auditor General of India (CAG), the official said, “CAG has done a detailed audit from 2006-07 to 2014-15 of the AGR dues. This evaluation will be done by us, for all the firms, all the quarters and all the 22 circles. ” In all, 16 entities owed the government an estimated Rs 1.47 trillion in AGR liabilities — Rs 92,642 crore in licence fee and another Rs 55,054 crore in outstanding spectrum usage charges. Of the dues that include interest and penalty for late payments, Airtel and Vodafone Idea accounted for 60 per cent. The Supreme Court last month rejected a plea by Airtel and Vodafone Idea for extension in the payment schedule and asked firms to deposit their past dues for spectrum and licences.
