"The impact on SSTL is severe as its licences have been cancelled in 21 circles, while for Tata Tele and Idea, the impact is limited, as their licences have been cancelled in only three and nine circles, respectively. For Bharti, the Vodafone group, and TTML, the licences remain unaffected," Crisil said in a release. The ratings on Tata Tele and Idea have been reaffirmed because revenues from the affected circles constitute less than 5% of their revenues from mobile services. Crisil has reaffirmed its ratings on Bharti, TTML, and the Vodafone group because the SC verdict is unlikely to impact their operations.
