Brookfield Infrastructure has entered into a $500 million revolving credit facility with Brookfield to provide additional liquidity for general corporate purposes and capital expenditures, if required. The revolving credit facility automatically renews for four consecutive one year terms, which would result in the facility ultimately maturing on February 8, 2023. Brookfield has the option to terminate the agreement prior to February 8 each year by providing Brookfield Infrastructure with written notice. Loans under this facility accrued interest on LIBOR plus 2.0% and no commitment fees were incurred for any undrawn balance. As of June 30, 2018, there were $nil (2017: $nil) borrowings outstanding.

The weakening of the Canadian dollar against the U.S. dollar during the six-month period ended June 30, 2018 resulted in a decrease in corporate borrowings of $56 million from December 31, 2017.

b) Non-Recourse Borrowings



	As of
US$ MILLIONS	June 30, 2018		December 31, 2017
Current	$	226	$	364
Non-current	9,463		7,699
Total	$	9,689	$	8,063

Non-recourse borrowings have increased by $1.6 billion since year-end. The increase is attributable to the issuance of $1.5 billion five-year senior notes at our Brazilian regulated gas transmission business in the local market at a rate of approximately 7.1% at the time of issuance, which was used to fund a return of capital to shareholders. The remaining increase is due to additional net borrowings of $100 million associated with growth capital projects at our operating entities, partially offset by a decrease in foreign denominated debt as currencies we operate in depreciated relative to the U.S. dollar during the six-month period ended June 30, 2018.
