New Delhi, Apr 29: India''s top mobile operator, Bharti Airtel, sees its current operating margin as sustainable, director Akhil Gupta said on Wednesday.
"I think anything around 40 per cent is pretty decent with this bond. But of course, if you do anything more in terms of converting opex into capex or vice-versa, this ratio can change," said Gupta.
Bharti, which announced its March quarter results earlier, recorded an operating margin of 40.7 per cent in the March quarter.
