Barcelona, (PTI) The Return on capital in the telecom business is very low and a tariff hike is likely to be the mid of this year, Bharti Airtel chairman Sunil Bharti Mittal said here on Monday.
While responding to a PTI query at the Mobile World Congress, Mittal said that the company has a healthy balance sheet and there is no need to raise any more capital.
"Lot of capital has been injected that has made the balance sheet strong but the return on capital of this industry is very low. That needs to change. We are talking of small increments that need to come in the Indian tariff situation. I hope half (by mid) of this year," Mittal said.
