Amendment Modification Description					The Company determined that the November 2017 Amendment was a modification of both the TCW Term Loan and PNC Credit Facility. In connection with this modification, the Company incurred $2.6 million in costs related to the TCW Term Loan (including $1.8 million related to the value of the November 2017 Amendment Warrants) and $0.8 million cash paid to TCW. These debt issuance costs were reflected as a reduction of the carrying amount of the TCW Term Loan and amortized to interest expense over the term of the TCW Term Loan. The Company also incurred $0.2 million in costs related to the amendment of the PNC Credit Facility which was recorded to other current assets and other assets and amortized to interest expense over the term of the PNC Credit Facility. Approximately $0.3 million in third party costs were expensed as incurred related to the November 2017 Amendment.

Debt instrument covenant description	The December 2018 Credit Agreements contain certain covenants, including requirements to prepay the loans in an amount equal to 100% of the net cash proceeds from certain assets dispositions, subject to certain reinvestment rights and other exceptions and equity issuances. Amounts outstanding under the December 2018 Credit Agreements may become due and payable upon the occurrence of specified events, which among other things include (subject to certain exceptions and cure periods) (i) failure to pay principal, interest, or any fees when due, (ii) breach of any representation or warranty, covenant, or other agreement, (iii) the occurrence of a bankruptcy or insolvency proceeding with respect to the Company or any of its subsidiaries, (iv) any event of default with respect to other indebtedness involving an aggregate amount of $1.0 million or more, (v) any lien created by the December 2018 Credit Agreements or any related security documents ceasing to be valid and perfected; (vi) the December 2018 Credit Agreements or any related security documents or guarantees ceasing to be legal, valid, and binding upon the parties thereto; or a change of control shall occur. The December 2018 Credit Agreements contain financial covenants relating to a fixed charge coverage ratio, minimum EBITDA and minimum liquidity. The Amended PNC Credit Facility also includes a total net leverage ratio and total leverage ratio covenants. As of March 31, 2019, the Company was in compliance with all covenants.
Debt instrument payment terms	The Senior Secured Term Loan contains a prepayment penalty which is calculated based on (i) if prepayment occurs prior to 30-month anniversary of the Closing Date, the prepayment penalty is the present value of all required interest payments due on the Senior Secured Term Loan that are prepaid from the date of prepayment through and including the 30-month anniversary of the Closing Date calculated based on the 3 month LIBOR Rate plus 10%, plus 5.0% of the amount of principal prepaid, (ii) if prepayment occurs between the 30-month anniversary of Closing Date through the third anniversary of the Closing Date, the prepayment penalty is 5.0% of the principal prepaid and (iii) if prepayment occurs between the third anniversary of the Closing Date through the fourth anniversary of Closing Date, the prepayment penalty is 2.0% of the principal prepaid (the "Prepayment Penalty"). There is no Prepayment Penalty after the fourth anniversary of the Closing Date. In addition to the Prepayment Penalty under the terms of the Senior Secured Term Loan, the Company is permitted to prepay up to 25% of the aggregate principal amount of the outstanding Senior Secured Term Loan balance with cash proceeds of a public offering of the Company's common stock at a prepayment premium of 12% of the principal amount being repaid.
