Debt and Financing Arrangements

DEBT AND FINANCING ARRANGEMENTS

Credit Facility

We, along with Williams and Northwest Pipeline LLC (Northwest) (the “borrowers”), are party to a Credit Agreement with aggregate commitments available of $4.5 billion, with up to an additional $500 million increase in aggregate commitments available under certain circumstances. We and Northwest are each subject to a $500 million borrowing sublimit. Letter of credit commitments of $1.0 billion are, subject to the $500 million borrowing sublimit applicable to us and Northwest, available to the borrowers. At March 31, 2019, no letters of credit have been issued and no loans were outstanding under the credit facility.

Williams participates in a commercial paper program and Williams management considers amounts outstanding under this program to be a reduction of available capacity under the credit facility. The program allows a maximum outstanding amount at any time of $4.0 billion of unsecured commercial paper notes. At March 31, 2019, Williams had $1.0 billion of outstanding commercial paper.
