Exclusive talks between Petroleo Brasileiro SA and Engie for gas pipeline network TAG, interrupted by court decisions, were resumed last month.

According to the sale process established by Brazil's audit court, the other two groups will be allowed to rebid, as long as they agree to the sale contract negotiated with Engie. One of the groups is led by Australia's Macquarie Bank, with Canada's CPPIB and Singapore's GIC Pte Ltd. The other is led by EIG Partners and sovereign wealth fund Mubadala Investment Co.

Petrobras did not immediately reply to a request for comment.
