Telenor ASA (OB:TEL) has restarted talks with Tata Teleservices (Maharashtra) Limited (BSE:532371) for a possible acquisition. The two companies had initiated discussions in 2012, but it went cold due to uncertainty over spectrum pricing and merger and acquisition norms. But now with the pricing issue set to get finalised in the spectrum auction in February, the two are back exploring options. While Tata Tele did not respond, a Telenor spokesperson said the company did not comment on speculations.
