Credit Facilities

On December 5, 2018, the Company entered into a 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 "Amended Agreement"). The Amended Agreement amended and restated in its entirety the Company's Fourth Amended and Restated Credit Agreement dated as of December 19, 2014 (the "Original Agreement"). The Amended 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 Amended 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 Amended 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 Amended Agreement extended the maturity date of the Original Agreement from January 3, 2020 to January 3, 2024 and decreased the interest rate payable on drawn amounts. Amounts drawn under the facility will continue to bear interest at 90-day LIBOR plus an applicable margin; however, the Amended Agreement reduced the applicable margin from a range of 2.50% to 3.50% to a range of 2.25% to 3.25%. 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 continues to be 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 Amended 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.

The Amended 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, 2019, no borrowings were outstanding on the revolving credit facility, $41.2 million of letters of credit were outstanding, and the revolving credit facility had $190.0 million of availability. The Company also had a separate unsecured letter of credit facility of up to $49.2 million as of March 31, 2019. Letters of credit totaling $49.1 million had been issued under the separate facility as of that date.

2019 Financings

On May 7, 2019, the Company obtained $111.1 million of debt secured by the non-recourse first mortgages on 14 communities. Sixty percent of the principal amount bears interest at a fixed rate of 4.52%, and the remaining forty percent of the principal amount bears interest at a variable rate equal to the 30-day LIBOR plus a margin of 223 basis points. The debt matures in 2029. The $111.1 million of proceeds from the financing along with cash on hand were utilized to repay $156 million of outstanding mortgage debt maturing in 2019.

Financial Covenants

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.

As of March 31, 2019, the Company is in compliance with the financial covenants of its debt agreements.
