4.	CREDIT FACILITY

On November 6, 2015, the Company entered into an Amended and Restated Credit Agreement that provides for a $50,000 unsecured revolving credit facility (the “Credit Facility”) with a lender. The Credit Facility can be drawn upon through November 6, 2020, at which time all amounts must be repaid. There were no borrowings outstanding at September 30, 2018 or December 31, 2017.

The Credit Facility provides for interest at either a base rate or a LIBOR rate, in each case plus an applicable margin. The base rate will be the highest of (i) the Administrative Agent’s prime rate, (ii) 0.50% above the Federal Funds Rate and (iii) the LIBOR rate for deposits in dollars for a one-month interest period as determined three business days prior to such date, plus 1.50%. The LIBOR rate is equal to the London Inter-Bank Offered Rate for the relevant term. The applicable margin is subject to adjustment based on the Company’s consolidated fixed charge coverage ratio and ranges from 0.00-0.50% per year for base rate loans and from 1.25-1.75% per year for LIBOR rate loans. The Company also pays an unused line fee. The unused line fee is 0.25% of the total available credit. During the three and nine months ended September 30, 2018, the Company incurred no interest expense and $32 and $95, respectively, in unused line fees under the Credit Facility. In the comparable periods of 2017, the Company incurred no interest expense and $32 and $95 in unused line fees, respectively. Interest payments and unused line fees are classified within interest income, net in the accompanying consolidated statements of operations.

The Credit Facility contains financial and other covenants including a minimum consolidated fixed charge coverage ratio (applicable if there are outstanding borrowings), and limitations on, among other things, liens, indebtedness, certain acquisitions, consolidations and sales of assets. As of September 30, 2018, the Company was in compliance with all covenants contained in the Credit Facility.

At September 30, 2018, the Company had $10 of unamortized debt issuance costs associated with the Credit Facility that are being amortized over its remaining term.
