Senior Secured Revolving Credit Facility

On October 28, 2016, the Company entered into a $125,000 revolving credit facility (the "Revolving Credit Facility"), with an initial term of five years.

On December 6, 2018, the Company and certain of its subsidiaries entered into a Second Amendment to Credit Agreement to exercise the $50 million accordion feature of its existing senior secured revolving credit facility and to add TCI as an additional guarantor. The Company’s credit facility, which matures in October 2021, increased capacity from $125 million to $175 million with the additional borrowing capacity being provided by the existing lenders. Other terms and conditions under the credit facility remain unchanged. At March 31, 2019 there was approximately $45,498 available under the Revolving Credit Facility.

Borrowings under the Revolving Credit Facility bear interest at the LIBOR Rate (as defined in the Credit Agreement) plus a margin of 1.00% to 2.25% or the Prime Rate (as defined in the Credit Agreement) plus a margin of 0% to 1.25%, in each case depending on the Company’s ratio of total funded indebtedness (as defined in the Credit Agreement) to Consolidated trailing twelve-month EBITDA (the “Total Leverage Ratio"). At March 31, 2019, the applicable margin for LIBOR Rate borrowings was 2.00% and the applicable margin for Prime Rate borrowings was 1.00%. In addition, the Company is required to pay a commitment fee of between 0.10% and 0.25% quarterly (currently 0.220%) on the unused portion of the Revolving facility, also based on the Company's Total Leverage Ratio. The Revolving Facility is secured by substantially all of the Company’s non-realty assets and is fully and unconditionally guaranteed by certain of the Company’s subsidiaries.

The Credit Agreement contains certain financial covenants related to minimum interest coverage and total leverage ratio at the end of each quarter. The Credit Agreement also includes other covenants and restrictions, including limits on the amount of additional indebtedness, and restrictions on the Company's ability to merge or sell all or substantially all of its assets. The Company was in compliance with all covenants at March 31, 2019.

There have been no borrowings during 2019 and there is no balance in the China Facility at March 31, 2019. There were no borrowings during the fourth quarter of 2018 and therefore no balance in the China Facility as of December 31, 2018.
