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 Revolving 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 December 31, 2020, the interest rate that was being charged on the outstanding principal amounts was 1.1%. 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. As of December 31, 2020, we had $1.4 billion available for draw down under the revolving credit facility.

We are required to disclose the fair value of financial instruments for which it is practicable to estimate the value, even though these instruments are not recognized at fair value in the consolidated balance sheets. As the Revolving Credit and Term Credit Agreements’ interest rate is calculated as LIBOR plus the spreads described above, its carrying amount is equivalent to its fair value as at December 31, 2020 and June 30, 2020, which was $329.0 million and $680.0 million, respectively. Quoted market prices in active markets for identical liabilities based inputs (Level 1) were used to estimate fair value.

On July 10, 2019, we entered into a Note Purchase Agreement with the purchasers to that agreement, in connection with the issuance and sale of $250.0 million principal amount of our 3.24% senior notes due July 10, 2026, and $250.0 million principal amount of our 3.45% senior notes due July 10, 2029 (collectively referred to as the “Senior Notes”). Our obligations under the Note Purchase Agreement and the Senior Notes are unconditionally and irrevocably guaranteed by certain of our direct and indirect U.S. subsidiaries, including ResMed Corp., ResMed Motor Technologies Inc., Birdie Inc., Inova Labs, Inc., Brightree LLC, Brightree Home Health & Hospice LLC, Brightree Patient Collections LLC, ResMed Operations Inc., HEALTHCAREfirst Holding Company, HCF Holdco Company, HEALTHCAREfirst, Inc., CareFacts Information Systems, LLC and Lewis Computer Services, LLC, MatrixCare Holdings Inc., MatrixCare, Inc., Reciprocal Labs Corporation and ResMed SaaS Inc., under a Subsidiary Guaranty Agreement dated as of July 10, 2019. The net proceeds from this transaction were used to pay down borrowings on our Revolving Credit Agreement.

Under the terms of the Note Purchase Agreement, we agreed to customary covenants including with respect to our corporate existence, transactions with affiliates, and mergers and other extraordinary transactions. We also agreed that, subject to limited exceptions, we will maintain a ratio of consolidated funded debt to consolidated EBITDA of no more than 3.50 to 1.00 as of the last day of any fiscal quarter, and will not at any time permit the amount of all priority secured and unsecured debt of us and our subsidiaries to exceed 10% of our consolidated tangible assets, determined as of the end of our most recently ended fiscal quarter.

We are required to disclose the fair value of financial instruments for which it is practicable to estimate the value, even though these instruments are not recognized at fair value in the consolidated balance sheets. As of December 31, 2020, the Senior Notes have a carrying amount of $500.0 million, excluding deferred borrowing costs, and an estimated fair value of $546.1 million. Quoted market prices in active markets for identical liabilities based inputs (Level 1) were used to estimate fair value.
