India’s top court on Thursday upheld a demand by the telecom department that wireless carriers pay 920 billion Indian rupees ($12.97 billion) in overdue levies and interest, TV channels reported, sending their shares tumbling.
The Department of Telecom (DoT) and mobile carriers have been sparring over the definition of adjusted gross revenue (AGR): companies argue that AGR should comprise just revenue accrued from core services, while the DoT says AGR should include all revenue.
Telecom providers pay DoT nearly 3-5% of AGR as usage charges for spectrum or airwaves and 8% of AGR as licence fees.
