On June 21, 2018, we entered into a revolving, unsecured credit agreement (“2018 Credit Agreement”) to replace our revolving, unsecured credit agreement dated as of February 7, 2014, as amended. The 2018 Credit Agreement currently provides for borrowings of up to $1.0 billion and matures on June 21, 2023. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on an average London inter-bank offered rate (“LIBOR”) for deposits in the relevant currency plus an applicable margin which ranges from 0.910% to 1.500%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services, Moody’s Investors Services and Fitch Ratings. The applicable margin on the facility was 1.125% as of September 30, 2018. There were no borrowings outstanding under the 2018 Credit Agreement as of September 30, 2018.
