At March 31, 2020 and December 31, 2019, the Company had $173.0 million and $90.0 million, respectively, of outstanding borrowings under its $250.0 million revolving credit facility. The Company estimates the fair value of its fixed rate debt by discounting the future cash flows of each instrument at estimated market rates. All of the Company's mortgage loans are fixed-rate. Rates take into consideration general market conditions, quality and estimated value of collateral and maturity of debt with similar credit terms and are classified within level 3 of the fair value hierarchy. The estimated fair value of the Company’s fixed rate debt as of March 31, 2020 and December 31, 2019 was $468.7 million and $501.5 million, respectively. The Company estimates the fair value of its variable rate debt by taking into account general market conditions and the estimated credit terms it could obtain for debt with similar maturity and is classified within level 3 of the fair value hierarchy. As of March 31, 2020, the Company’s only variable rate debt is under its revolving credit facility. The estimated fair value of the Company’s variable rate debt as of March 31, 2020 and December 31, 2019 was $173.0 million and $90.0 million, respectively. As of March 31, 2020, the Company was in compliance with all of its financial covenants. On May 6, 2020, the company amended its credit facility to provide it with certain relief from the effects of the COVID-19 pandemic. The amendment provides for the waiver of certain financial covenants through March 31, 2021 and allows Chatham to borrow up to the entire $250 million facility size during this period. During this covenant waiver period, Chatham will be required to maintain a minimum liquidity of $25 million which will include both unrestricted cash and credit facility availability. In connection with the amendment, Chatham added six hotels to the credit facility’s borrowing base which now has a total of 18 properties. The amendment provided Chatham’s credit facility lenders with pledges of the equity in the 18 borrowing base hotels. The amendment places additional limits on Chatham’s ability to incur debt, pay dividends, and make capital expenditures during the covenant waiver period. During the covenant waiver period interest will be calculated as LIBOR (subject to a 0.5% floor) plus a spread of 2.5% if borrowings remain at or below $200 million and a spread of 3.0% if borrowings exceed $200 million. See Note 15 for additional details.
