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 has an effective date of February 8, 2018 and automatically renews for four consecutive one year terms on the first, second, third and fourth anniversary of such effective date, which would result it in 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. All obligations of Brookfield Infrastructure under the facility were guaranteed by our partnership. Loans under this facility accrued interest on LIBOR plus 2.00% and no commitment fees were incurred for any undrawn balance. As of December 31, 2017, there were $nil (2016: $nil) of borrowings outstanding.
