\
(1) | In August 2017, Brookfield Infrastructure, alongside institutional partners and a Brookfield-sponsored infrastructure fund, reorganized the holding entities of its investment in the Brazilian toll road operation. This transaction resulted in no gain or loss being recorded within the Consolidated Statements of Operating Results. The reorganization resulted in Brookfield Infrastructure no longer consolidating an 8% interest of the investment attributable to an institutional partner. The reorganization concurrently reduced the investments in associates and joint venture and non-controlling interest partnership capital balances by $177 million during the third quarter of 2017.
(2) | Throughout 2017, Brookfield Infrastructure, alongside an institutional partner, injected $349 million into the Brazilian toll road operation for growth capital expenditure requirements increasing our partnership’s ownership interest to 45%.
(3) | Share of earnings for the year ended December 31, 2016 includes $195 million of non-recurring gains primarily related to our transport and energy operations.
(4) | In May 2017, Brookfield Infrastructure and its partner in its North American natural gas transmission operation each injected $200 million into the business to pay down operating level debt. A similar transaction was completed in April 2016 by Brookfield Infrastructure and its partner in the amount of $312 million.
(5) | During December 2017, our partnership signed an agreement to sell our ownership in ETC Transmission Holdings. Completion of this transaction is subject to certain closing conditions, third party consents and regulatory approvals.
(6) | In August 2016, Brookfield Infrastructure expanded its ports operations in Australia as it acquired an effective 13% interest in PTH No 1 Pty Ltd (“Patrick”) through a Brookfield-sponsored infrastructure fund, alongside institutional partners, for total consideration of $202 million. The Brookfield consortium maintains 50% of the voting rights of Patrick in a joint venture with Qube Holdings Limited, along with its institutional partners. Brookfield Infrastructure has joint control through its position in the business. Accordingly, Brookfield Infrastructure equity accounts for the entity.
(7) | Other includes our partnership’s Texas electricity transmission project, Brazil electricity transmission operation, European port operation, North American west coast container terminal, U.S. gas storage operation and other investments in associates and joint ventures held through consolidated subsidiaries.
