Network i2i, a wholly-owned subsidiary of Bharti Airtel, is planning to raise $250 million through perpetual bonds.

To this end, Network i2i has approached investors for the proposed additional issuance of its 5.65 per cent subordinated perpetual notes.

Recently Bharti Airtel had raised securities worth $750 million. It had said that the proceeds from the issue would be utilised to pare debt.
