Credit Facility

On April 17, 2018, we entered into an amended and restated credit agreement (the “Revolving Credit Agreement”), as borrower, with lenders MUFG Union Bank, N.A., as administrative agent, joint lead arranger, joint book runner, swing line lender and letter of credit issuer, and Westpac Banking Corporation, as syndication agent, joint lead arranger and joint book runner. The Amended and Restated Credit Agreement, among other things, provided a senior unsecured revolving credit facility of $800.0 million, with an uncommitted option to increase the revolving credit facility by an additional $300.0 million.

Additionally, on April 17, 2018, ResMed Limited entered into a Syndicated Facility Agreement (the “Term Credit Agreement”), as borrower, with lenders MUFG Union Bank, N.A., as administrative agent, joint lead arranger and joint book runner, and Westpac Banking Corporation, as syndication agent, joint lead arranger and joint book runner. The Term Credit Agreement, among other things, provides ResMed Limited a senior unsecured term credit facility of $200.0 million.

On November 5, 2018, we entered into a first amendment to the Revolving Credit Agreement to, among other things, increase the size of our senior unsecured revolving credit facility from $800.0 million to $1.6 billion, with an uncommitted option to increase the revolving credit facility by an additional $300.0 million.

Our obligations under the Revolving Credit Agreement are guaranteed by certain of our direct and indirect U.S. subsidiaries, and ResMed Limited’s obligations under the Term Credit Agreement are guaranteed by us and certain of our direct and indirect U.S. subsidiaries. The Revolving Credit Agreement and Term Credit Agreement contain customary covenants, including, in each case, a financial covenant that requires that we maintain a maximum leverage ratio of funded debt to EBITDA (as defined in the Revolving Credit Agreement and Term Credit Agreement, as applicable). The entire principal amounts of the revolving credit facility and term credit facility, and, in each case, any accrued but unpaid interest may be declared immediately due and payable if an event of default occurs, as defined in the Revolving Credit Agreement and the Term Credit Agreement, as applicable. Events of default under the Revolving Credit Agreement and the Term Credit Agreement include, in each case, failure to make payments when due, the occurrence of a default in the performance of any covenants in the respective agreements or related documents, or certain changes of control of us, or the respective guarantors of the obligations borrowed under the Revolving Credit Agreement and Term Credit Agreement.

The Revolving Credit Agreement and Term Credit Agreement each terminate on April 17, 2023, when all unpaid principal and interest under the loans must be repaid. Amounts borrowed under the Term Credit Agreement will also amortize on a semi-annual basis, with a $6.0 million principal payment required on each such semi-annual amortization date. The outstanding principal amounts will bear interest at a rate equal to LIBOR plus 0.75% to 1.50% (depending on the then-applicable leverage ratio) or the Base Rate (as defined in the Revolving Credit Agreement and the Term Credit Agreement, as applicable) plus 0.0% to 0.50% (depending on the then-applicable leverage ratio). At March 31, 2019, the interest rate that was being charged on the outstanding principal amounts was 3.6%. An applicable commitment fee of 0.100% to 0.175% (depending on the then-applicable leverage ratio) applies on the unused portion of the revolving credit facility. At March 31, 2019, we were in compliance with our debt covenants and there was $1,339.0 million outstanding under the Revolving Credit Agreement and Term Credit Agreement.
