On October 23, 2018, we entered into a Sixth Amendment (the “Sixth Amendment”) to our credit agreement dated as of November 15, 2010, as amended on March 15, 2011, September 21, 2012, May 16, 2013, August 7, 2014 and June 7, 2016, among UHS, as borrower, the several banks and other financial institutions from time to time parties thereto, as lenders, JPMorgan Chase Bank, N.A., as administrative agent, and the other agents party thereto (the “Senior Credit Agreement”).

The Sixth Amendment to the Senior Credit Agreement, among other things: (i) increased the aggregate amount of the revolving credit facility to $1 billion (increase of $200 million over the $800 million previous commitment); (ii) increased the aggregate amount of the tranche A term loan commitments to $2 billion (increase of approximately $290 million over the $1.71 billion of outstanding borrowings prior to the amendment), and; (iii) extended the maturity date of the revolving credit and tranche A term loan facilities to October 23, 2023 from August 7, 2019.

On October 31, 2018, we added a seven-year tranche B term loan facility in the aggregate principal amount of $500 million pursuant to the Senior Credit Agreement. The tranche B term loan matures on October 31, 2025. We used the proceeds to repay borrowings under the revolving credit facility, the Securitization (as defined below), to redeem our $300 million, 3.75% Senior Notes that were scheduled to mature in 2019 and for general corporate purposes.

As of December 31, 2020, we had no borrowings outstanding pursuant to our $1 billion revolving credit facility and we had $997 million of available borrowing capacity net of $3 million of outstanding letters of credit.

Pursuant to the terms of the Sixth Amendment, the tranche A term loan, which had $1.900 billion of borrowings outstanding as of December 31, 2020, provided for eight installment payments of $12.5 million per quarter which commenced in March of 2019 and continued through December of 2020. Payments of $25 million per quarter are scheduled, commencing in March of 2021 until maturity in October of 2023, when all outstanding amounts will be due.

The tranche B term loan, which had $490 million of borrowings outstanding as of December 31, 2020, provides for installment payments of $1.25 million per quarter, which commenced on March 31, 2019 and are scheduled to continue until maturity in October of 2025, when all outstanding amounts will be due.

Borrowings under the Senior Credit Agreement bear interest at our election at either (1) the ABR rate which is defined as the rate per annum equal to the greatest of (a) the lender’s prime rate, (b) the weighted average of the federal funds rate, plus 0.5% and (c) one month LIBOR rate plus 1%, in each case, plus an applicable margin based upon our consolidated leverage ratio at the end of each quarter ranging from 0.375% to 0.625% for revolving credit and term loan A borrowings and 0.75% for tranche B borrowings, or (2) the one, two, three or six month LIBOR rate (at our election), plus an applicable margin based upon our consolidated leverage ratio at the end of each quarter ranging from 1.375% to 1.625% for revolving credit and term loan A borrowings and 1.75% for the tranche B term loan. As of December 31, 2020, the applicable margins were 0.375% for ABR-based loans and 1.375% for LIBOR-based loans under the revolving credit and term loan A facilities. The revolving credit facility includes a $125 million sub-limit for letters of

credit. The Senior Credit Agreement is secured by certain assets of the Company and our material subsidiaries (which generally excludes asset classes such as substantially all of the patient-related accounts receivable of our acute care hospitals, and certain real estate assets and assets held in joint-ventures with third parties) and is guaranteed by our material subsidiaries.

The Senior Credit Agreement includes a material adverse change clause that must be represented at each draw. The Senior Credit Agreement contains covenants that include a limitation on sales of assets, mergers, change of ownership, liens and indebtedness, transactions with affiliates, dividends and stock repurchases; and requires compliance with financial covenants including maximum leverage. We are in compliance with all required covenants as of December 31, 2020 and December 31, 2019.

In April, 2018, we entered into the sixth amendment to our accounts receivable securitization program (“Securitization”) dated as of October 27, 2010 with a group of conduit lenders, liquidity banks, and PNC Bank, National Association, as administrative agent, which provides for borrowings outstanding from time to time by certain of our subsidiaries in exchange for undivided security interests in their respective accounts receivable. The sixth amendment, among other things, extended the term of the Securitization program through April 26, 2021 and increased the borrowing capacity to $450 million (from $440 million previously). In July, 2020, we entered into the seventh amendment to the Securitization which temporarily waived the minimum borrowing requirement through September 30, 2020. Pursuant to the terms of our Securitization program, substantially all of the patient-related accounts receivable of our acute care hospitals (“Receivables”) serve as collateral for the outstanding borrowings. We have accounted for this Securitization as borrowings. We maintain effective control over the Receivables since, pursuant to the terms of the Securitization, the Receivables are sold from certain of our subsidiaries to special purpose entities that are wholly-owned by us. The Receivables, however, are owned by the special purpose entities, can be used only to satisfy the debts of the wholly-owned special purpose entities, and thus are not available to us except through our ownership interest in the special purpose entities. The wholly-owned special purpose entities use the Receivables to collateralize the loans obtained from the group of third-party conduit lenders and liquidity banks. The group of third-party conduit lenders and liquidity banks do not have recourse to us beyond the assets of the wholly-owned special purpose entities that securitize the loans. At December 31, 2020, we had $225 million of outstanding borrowings pursuant to the terms of the Securitization (which are included in current maturities of long-term debt at December 31, 2020) and $225 million of available borrowing capacity. We believe that our operating cash flows, cash and cash equivalents, as well as access to the capital markets, provides us with sufficient capital resources to fund our operating, investing and financing requirements over the next twelve months, including repayment or refinancing of our Securitization which is scheduled to mature in April, 2021.

As of December 31, 2020, we had combined aggregate principal of $1.2 billion from the following senior secured notes:

Interest on the 2026 Notes is payable on June 1 and December 1 until the maturity date of June 1, 2026. Interest on the 2030 Notes payable on April 15 and October 15, commencing April 15, 2021, until the maturity date of October 15, 2030. The 2026 Notes and 2030 Notes were offered only to qualified institutional buyers under Rule 144A and to non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The 2026 Notes and 2030 Notes have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The 2030 Notes are guaranteed (the “Guarantees”) on a senior secured basis by all of our existing and future direct and indirect subsidiaries (the “Subsidiary Guarantors”) that guarantee our Senior Credit Agreement, dated as of November 15, 2010, as amended, restated or supplemented from time to time, or other first lien obligations or any junior lien obligations. The 2030 Notes and the Guarantees are secured by first-priority liens, subject to permitted liens, on certain of the Company’s and the Subsidiary Guarantors’ assets now owned or acquired in the future by the Company or the Subsidiary Guarantors (other than real property, accounts receivable sold pursuant to the Company’s Existing Receivables Facility (as defined in the Indenture pursuant to which the 2030 Notes were issued (the “Indenture”)), and certain other excluded assets). The Company’s obligations with respect to the 2030 Notes, the obligations of the Subsidiary Guarantors under the Guarantees, and the performance of all of the Company’s and the Subsidiary Guarantors’ other obligations under the Indenture are secured equally and ratably with the Company’s and the Subsidiary Guarantors’ obligations under the Senior Credit Agreement and the Company’s 2026 Notes by a perfected first-priority security interest, subject to permitted liens, in the collateral owned by the Company and its Subsidiary Guarantors, whether now owned or hereafter acquired. However, the liens on the collateral securing the 2030 Notes and the Guarantees will be released if: (i) the 2030 Notes have investment grade ratings; (ii) no default has occurred and is continuing, and; (iii) the liens on the collateral securing all first lien obligations (including the Senior Credit Agreement and the 2026 Notes) and any junior lien obligations are released or the collateral under the Senior Credit Agreement, any other first lien obligations and any junior lien obligations is released or no longer required to be pledged. The liens on any collateral securing the 2030 Notes and the Guarantees will also be released if the liens on that collateral securing the Senior Credit Agreement, other first lien obligations and any junior lien obligations are released.

In connection with the issuance of the 2030 Notes, the Company, the Subsidiary Guarantors and the representatives of the several initial purchasers, entered into a Registration Rights Agreement (the “Registration Rights Agreement”), whereby the Company and the Subsidiary Guarantors have agreed, at their expense, to use commercially reasonable best efforts to: (i) cause to be filed a registration statement enabling the holders to exchange the 2030 Notes and the Guarantees for registered senior secured notes issued by the Company and guaranteed by the then Subsidiary Guarantors under the Indenture (the “Exchange Securities”), containing terms identical to those of the 2030 Notes (except that the Exchange Securities will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the Registration Rights Agreement); (ii) cause the registration statement to become effective; (iii) complete the exchange offer not later than 60 days after such effective date and in any event on or prior to a target registration date of March 21, 2023, and; (iv) file a shelf registration statement for the resale of the 2030 Notes if the exchange offer cannot be effected within the time periods listed above. The interest rate on the 2030 Notes will increase and additional interest thereon will be payable if the Company does not comply with its obligations under the Registration Rights Agreement.

On September 28, 2020, we redeemed the entire $700 million aggregate principal amount of our previously outstanding 4.75% Senior Secured Notes due 2022 (the “2022 Notes”), at a cash redemption price equal to the sum of: (i) 100% of the aggregate principal amount of the 2022 Notes redeemed, and; (ii) accrued and unpaid interest on the 2022 Notes to the redemption date. Included in our financial results for the three and nine-month periods ended September 30, 2020, was a loss on extinguishment of debt of approximately $1 million recorded in connection with the redemption of the 2022 Notes.

At December 31, 2020, the carrying value and fair value of our debt were each approximately $3.9 billion. At December 31, 2019, the carrying value and fair value of our debt were each approximately $4.0 billion. The fair value of our debt was computed based upon quotes received from financial institutions. We consider these to be “level 2” in the fair value hierarchy as outlined in the authoritative guidance for disclosures in connection with debt instruments.

The aggregate scheduled maturities of our total debt outstanding as of December 31, 2020 are as follows:
