The Company's Fifth Amended and Restated Credit Agreement with Capital One, National Association, as administrative agent, lender and swingline lender and the other lenders from time to time parties thereto (the "Credit Agreement"), provides commitments for a $250 million revolving credit facility with a $60 million sublimit for letters of credit and a $50 million swingline feature. The Company has a one-time right under the Credit Agreement to increase commitments on the revolving credit facility by an additional $100 million, subject to obtaining commitments for the amount of such increase from acceptable lenders. The Credit Agreement provides the Company a one-time right to reduce the amount of the revolving credit commitments, and the Company

may terminate the revolving credit facility at any time, in each case without payment of a premium or penalty. The Credit Agreement matures on January 3, 2024. Amounts drawn under the facility bear interest at 90-day LIBOR plus an applicable margin. The applicable margin varies based on the percentage of the total commitment drawn, with a 2.25% margin at utilization equal to or lower than 35%, a 2.75% margin at utilization greater than 35% but less than or equal to 50%, and a 3.25% margin at utilization greater than 50%. A quarterly commitment fee is payable on the unused portion of the facility at 0.25% per annum when the outstanding amount of obligations (including revolving credit and swingline loans and letter of credit obligations) is greater than or equal to 50% of the revolving credit commitment amount or 0.35% per annum when such outstanding amount is less than 50% of the revolving credit commitment amount.

The credit facility is secured by first priority mortgages on certain of the Company's communities. In addition, the Credit Agreement permits the Company to pledge the equity interests in subsidiaries that own other communities and grant negative pledges in connection therewith (rather than mortgaging such communities), provided that not more than 10% of the borrowing base may result from communities subject to negative pledges. Availability under the revolving credit facility will vary from time to time based on borrowing base calculations related to the appraised value and performance of the communities securing the credit facility and the Company's consolidated fixed charge coverage ratio. To the extent the outstanding borrowings on the credit facility exceed future borrowing base calculations, the Company would be required to repay the difference to restore the outstanding balance to the new borrowing base.

During 2019, parties entered into an amendment to the Credit Agreement that provides for availability calculations to be made at additional consolidated fixed charge coverage ratio thresholds.

The Credit Agreement contains typical affirmative and negative covenants, including financial covenants with respect to minimum consolidated fixed charge coverage and minimum consolidated tangible net worth. Amounts drawn on the credit facility may be used for general corporate purposes.

As of March 31, 2020, $166.4 million of borrowings were outstanding on the revolving credit facility, $48.1 million of letters of credit were outstanding, and the revolving credit facility had $35.3 million of availability. The Company also had a separate unsecured letter of credit facility of up to $50.0 million of letters of credit as of March 31, 2020 under which $47.5 million had been issued as of that date.

During March 2020, the Company completed its financing plans in the regular course of business, including closing non-recourse mortgage debt financing transactions as described below. As of March 31, 2020, the Company’s remaining 2020 and 2021 maturities are $69.7 million and $333.1 million, respectively, and the Company has commenced efforts to refinance those and other maturities with non-recourse mortgage debt. There is no assurance that debt financing will continue to be available on terms consistent with the Company’s expectations or at all.

On January 31, 2020, the Company obtained $238.2 million of debt secured by the non-recourse first mortgages on 14 communities, including $192.6 million of non-recourse first mortgage financing on 13 communities acquired from Healthpeak on such date. Seventy percent of the principal amount bears interest at a fixed rate of 3.62%, and the remaining thirty percent of the principal amount bears interest at a variable rate equal to 30-day LIBOR plus a margin of 209 basis points. The debt matures in February 2030. The proceeds from the financing were utilized to fund the acquisition of communities from Healthpeak and repay $33.1 million of outstanding mortgage debt maturing in 2020. Refer to Note 4 for more information about the Company's acquisition of communities from Healthpeak.

On March 19, 2020, the Company obtained $29.2 million of debt secured by the non-recourse first mortgages on seven communities, primarily communities acquired during the three months ended March 31, 2020. The loan bears interest at a variable rate equal to the 30-day LIBOR plus a margin of 225 basis points and matures in April 2030.

On March 20, 2020, the Company obtained $30.0 million of debt secured by the non-recourse first mortgage on one community acquired from Healthpeak on January 31, 2020. The loan bears interest at a variable rate equal to the 30-day LIBOR plus a margin of 250 basis points and matures in March 2022.

On March 31, 2020, the Company obtained $149.3 million of debt secured by the non-recourse first mortgages on 18 communities. Of the total principal, $73.1 million bears interest at a fixed rate of 3.55%, and the remaining $76.2 million bears interest at a variable rate equal to the 30-day LIBOR plus a margin of 210 basis points. The debt matures in April 2030. The $149.3 million of proceeds from the financing were primarily utilized to repay $136.3 million of outstanding mortgage debt maturing in 2020.

Certain of the Company's debt documents contain restrictions and financial covenants, such as those requiring the Company to maintain prescribed minimum net worth and stockholders' equity levels and debt service ratios, and requiring the Company not to exceed prescribed leverage ratios, in each case on a consolidated, portfolio-wide, multi-community, single-community, and/or entity basis. In addition, the Company's debt documents generally contain non-financial covenants, such as those requiring the Company to comply with Medicare or Medicaid provider requirements.

The Company's failure to comply with applicable covenants could constitute an event of default under the applicable debt documents. Many of the Company's debt documents contain cross-default provisions so that a default under one of these instruments could cause a default under other debt and lease documents (including documents with other lenders and lessors). Furthermore, the Company's debt is secured by its communities and, in certain cases, a guaranty by the Company and/or one or more of its subsidiaries.
