The borrower under the Credit Facility is our wholly-owned subsidiary CHS/Community Health Systems, Inc., or CHS. All of our obligations under the Credit Facility are unconditionally guaranteed by Community Health Systems, Inc. and certain of its existing and subsequently acquired or organized domestic subsidiaries. All obligations under the Credit Facility and the related guarantees are secured by a perfected first priority lien or security interest in substantially all of the assets of Community Health Systems, Inc., CHS and each subsidiary guarantor, including equity interests held by us or any subsidiary guarantor, but excluding, among others, the equity interests ofnon-significant subsidiaries, syndication subsidiaries, securitization subsidiaries and joint venture subsidiaries. Such assets constitute substantially the same assets, subject to certain exceptions, that secure CHS’ obligations under its outstanding first lien senior secured notes and, on a junior-priority basis, its outstanding junior-priority secured notes.
We have agreed to pay letter of credit fees equal to the applicable percentage then in effect with respect to LIBOR borrowings under the Revolving Facility times the maximum aggregate amount available to be drawn under all letters of credit outstanding under the subfacility for letters of credit. The issuer of any letter of credit issued under the subfacility for letters of credit will also receive a customary fronting fee and other customary processing charges. We are obligated to pay commitment fees of 0.50% per annum (subject to adjustment based upon our leverage ratio), on the unused portion of the Revolving Facility.
The Credit Facility contains customary representations and warranties, subject to limitations and exceptions, and customary covenants restricting our and our subsidiaries’ ability, subject to certain exceptions, to, among other things, (1) declare dividends, make distributions or redeem or repurchase capital stock, (2) prepay, redeem or repurchase other debt, (3) incur liens or grant negative pledges, (4) make loans and investments and enter into acquisitions and joint ventures, (5) incur additional indebtedness or provide certain guarantees, (6) make capital expenditures, (7) engage in mergers, acquisitions and asset sales, (8) conduct transactions with affiliates, (9) alter the nature of our businesses, (10) grant certain guarantees with respect to physician practices, (11) engage in sale and leaseback transactions or (12) change our fiscal year. We and our subsidiaries are also required to comply with specified financial covenants (consisting of a maximum first lien net debt to consolidated EBITDA leverage ratio) and various affirmative covenants. Under the Credit Facility, the first lien net debt to consolidated EBITDA leverage ratio is calculated as the ratio of total first lien debt, less unrestricted cash and cash equivalents, to consolidated EBITDA, as defined in the Credit Facility. The calculation of consolidated EBITDA as defined in the Credit Facility is a trailing12-month calculation that begins with net income attributable to us, with certain pro forma adjustments to consider the impact of material acquisitions or divestitures, and adjustments for interest, taxes, depreciation and amortization, net income attributable to noncontrolling interests, stock compensation expense, restructuring costs, and the financial impact of othernon-cash ornon-recurring items recorded during any such12-month period. For the12-month period ended March 31, 2019, the first lien net debt to consolidated EBITDA leverage ratio financial covenant under the Credit Facility limited the ratio of first lien net debt to consolidated EBITDA, as defined, to less than or equal to 5.25 to 1.0. We were in compliance with all such covenants at March 31, 2019, with a first lien net debt to consolidated EBITDA leverage ratio of approximately 4.98 to 1.0.
Events of default under the Credit Facility include, but are not limited to, (1) our failure to pay principal, interest, fees or other amounts under the credit agreement when due (taking into account any applicable grace period), (2) any representation or warranty proving to have been materially incorrect when made, (3) covenant defaults subject, with respect to certain covenants, to an available cure, (4) bankruptcy and insolvency events, (5) a cross default to certain other debt, (6) certain undischarged judgments (not paid within an applicable grace period), (7) a change of control (as defined), (8) certain ERISA-related defaults and (9) the invalidity or impairment of specified security interests, guarantees or subordination provisions in favor of the administrative agent or lenders under the Credit Facility.
On February 15, 2019, the Credit Facility was amended, with requisite covenant lender approval, to amend the first lien net debt to EBITDA ratio financial covenant and to reduce the extended revolving credit commitments to $385 million. The amended financial covenant provides for a maximum first lien net debt to EBITDA ratio of 5.00 to 1.0 from July 1, 2018 through December 31, 2018, 5.25 to 1.0 from January 1, 2019 through December 31, 2019, 5.00 to 1.00 from January 1, 2020 through June 30, 2020, 4.50 to 1.00 from July 1, 2020 through September 30, 2020, and 4.25 to 1.0 thereafter. In addition, CHS agreed to further restrict its ability to make restricted payments. The revolving credit commitments will terminate on January 27, 2021. The amended Credit Facility includes a91-day springing maturity date applicable if more than $250 million in the aggregate principal amount of our 8% Senior Notes due 2019, 71⁄8% Senior Notes due 2020, Term H Facility or refinancings thereof are scheduled to mature or similarly become due within 91 days of such date.
