Borrowings Under Credit Facilities and Commercial Paper Program

Borrowings Under Credit Facilities and Commercial Paper Program At March 31, 2021, we had a primary unsecured credit facility with a consortium of 31 banks that includes a $3,000,000,000 unsecured revolving credit facility (none outstanding at March 31, 2021), a $500,000,000 unsecured term credit facility and a $250,000,000 Canadian-denominated unsecured term credit facility. We have an option, through an accordion feature, to upsize the unsecured revolving credit facility and the $500,000,000 unsecured term credit facility by up to an additional $1,000,000,000, in the aggregate, and the $250,000,000 Canadian-denominated unsecured term credit facility by up to an additional $250,000,000. The primary unsecured credit facility also allows us to borrow up to $1,000,000,000 in alternate currencies (none outstanding at March 31, 2021). Borrowings under the unsecured revolving credit facility are subject to interest payable at the applicable margin over LIBOR interest rate. The applicable margin is based on our debt ratings and was 0.825% at March 31, 2021. In addition, we pay a facility fee quarterly to each bank based on the bank’s commitment amount. The facility fee depends on our debt ratings and was 0.15% at March 31, 2021. The term credit facilities mature on July 19, 2023. The revolving credit facility is scheduled to mature on July 19, 2022 and can be extended for two successive terms of six months each at our option.

In January 2019, we established an unsecured commercial paper program. Under the terms of the program, we may issue unsecured commercial paper notes with maturities that vary, but do not exceed 397 days from the date of issue, up to a maximum aggregate face or principal amount outstanding at any time of $1,000,000,000 (none outstanding at March 31, 2021).
