On December 7, 2017, we entered into a senior secured term credit agreement (the “Term Credit Agreement”), pursuant to which JPMorgan Chase Bank N.A., Bank of America, N.A. and Kirkpatrick Bank agreed to make certain term loans to us (the “Term Loans”) in an aggregate principal amount of $60.0 million on or prior to September 7, 2018. As of June 30, 2018, our indebtedness consisted solely of Term Loans made under the Term Credit Agreement. Unamortized debt issuance costs of $0.2 million as of both June 30, 2018 and December 31, 2017 are presented as a direct deduction from the carrying amount of the debt liability.

After giving effect to the Term Loans made on December 7, 2017, there was $24.5 million of borrowing capacity remaining under the Term Credit Agreement as of June 30, 2018. Our obligations under the Term Loans are secured by a mortgage and first priority security interest in our headquarters property. Term Loans made after December 7, 2017 may be used to finance hard and soft costs related to the completion of construction of our fourth headquarters building and any landscaping, groundwork, parking lots and roads reasonably incidental thereto. The Term Loans mature on September 7, 2025 and bear interest, at our option, at either (a) a prime rate plus 1.0% or (b) an adjusted LIBOR rate for the interest period in effect for such Term Loan plus 1.5%.

Under the Term Credit Agreement, we are subject to two material financial covenants, which require us to maintain a fixed charge coverage ratio of not less than 1.25 to 1.0 and a funded indebtedness to EBITDA ratio of not greater than 2.0 to 1.0. As of June 30, 2018, we were in compliance with these covenants.

On February 12, 2018, we entered into a senior secured revolving credit agreement (the “Revolving Credit Agreement”) with JPMorgan Chase Bank, N.A. and Bank of America, N.A. that provides for a senior secured revolving credit facility (the “Facility”) in the aggregate principal amount of $50.0 million, which may be increased to up to $100.0 million, subject to obtaining additional lender commitments and certain approvals and satisfying certain other conditions. The Facility includes a $5.0 million sublimit for swingline loans and a $2.5 million sublimit for letters of credit. The Facility is scheduled to mature on February 12, 2020. Borrowings under the Facility will generally bear interest at a prime rate plus 1.0% or, at our option, an adjusted LIBOR rate for the interest period in effect for such borrowing plus 1.5%. The proceeds of the loans and letters of credit under the Facility are to be used only for our general business purposes and working capital. Letters of credit are to be issued only to support our business operations. As of June 30, 2018, we have not made any draws under the Facility.

Under the Revolving Credit Agreement, we are required to maintain a fixed charge coverage ratio of not less than 1.25 to 1.0 and a funded indebtedness to EBITDA ratio of not greater than 2.0 to 1.0. Additionally, the Revolving Credit Agreement contains customary affirmative and negative covenants, including covenants limiting our ability to, among other things, grant liens, incur debt, effect certain mergers, make investments, dispose of assets, enter into certain transactions, including swap agreements and sale and leaseback transactions, pay dividends or distributions on our capital stock, and enter into transactions with affiliates, in each case subject to customary exceptions for a facility of the size and type of the Facility.

As of June 30, 2018 and December 31, 2017, the carrying value of our total long-term debt approximated its fair value as of such date. The fair value of our long-term debt is estimated based on the borrowing rates currently available to us for bank loans with similar terms and maturities.
