The CAG had said that the spectrum allocated resulted in notional loss of Rs 1.76 lakh crore to the national exchequer.
The government in October 2016 auctioned spectrum worth Rs 5.66 lakh crore but received bids worth only Rs 65,789 crore.

In short, stress on the corporate sector is not only deepening; it is also widening.
