Australia's TPG Telecom said on Wednesday the exclusive due diligence period granted to Macquarie-backed rival Vocus Group for the A$6.3 billion sale of its non-mobile fiber assets has expired. Discussions between the parties for the commercial terms of the deal remain ongoing, with the consideration subjected to change, TPG said in a statement. The bid, made in August, includes TPG's non-mobile fibre assets such as certain Enterprise, Government and Wholesale (EGW) assets and associated fixed infrastructure assets, including the wholesale broadband business, Vision Network.
