Debt Disclosure [Abstract]
Revolving Credit Facility	6. Revolving Credit Facility We entered into a Loan, Security and Guaranty Agreement (the “Citizens Loan Agreement”), dated as of February 24, 2017, with Citizens Bank, National Association as a lender, and as administrative agent, collateral agent, and issuing bank, which provides for an asset-based revolving credit facility (the “ABL Facility”) of up to $20 million and an equipment loan facility in the maximum principal amount of $2.0 million. Available borrowings on the ABL facility are based on formula-determined amounts of eligible trade receivables, as defined in the Citizens Loan Agreement, and are recalculated on a monthly basis. Each loan under the ABL Facility bears interest, at our option, at either the Base Rate, as defined in the Citizens Loan Agreement, plus a margin ranging from 1.0% to 1.5% (6.00% as of December 31, 2019), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.09% as of December 31, 2019). The maturity date of the ABL Facility is February 24, 2022. LIBOR is expected to be discontinued after 2021. The ABL Facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. However, there can be no assurances as to whether such replacement or alternative rate will be more or less favorable than LIBOR. We intend to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and will work with Citizens Bank, National Association to ensure any transition away from LIBOR will have minimal impact on our financial condition. We however can provide no assurances regarding the impact of the discontinuation of LIBOR on the interest rate that we would be required to pay or on our financial condition. We had no borrowings under the equipment loan facility, which were required to be requested no later than February 24, 2019. The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. In addition, the ABL Facility contains negative covenants limiting, among other things, additional indebtedness, transactions with affiliates, additional liens, sales of assets, dividends, investments and advances, mergers and acquisitions, and other matters customarily restricted in such agreements. As of December 31, 2019, we were in compliance with the financial covenants included in the Citizens Loan Agreement. Quest and LDI are the borrowers under the Citizens Loan Agreement. QRHC and QSS are guarantors under the Citizens Loan Agreement. In addition, obligations under the ABL Facility are secured by certain first-priority security interests in substantially all of the tangible and intangible personal property of the borrowers, including a pledge of the capital stock and membership interests, as applicable, of certain of their direct and indirect subsidiaries. The guarantors under the Citizens Loan Agreement have granted a first priority lien on the capital stock and membership interests, as applicable, of certain of their direct and indirect subsidiaries. The amount of interest expense related to borrowings for the years ended December 31, 2019 and 2018 was $326,212 and $325,534, respectively. Debt issuance cost of $469,507 is being amortized to interest expense over the life of the ABL Facility. As of December 31, 2019, the unamortized portion of the debt issuance costs was $203,453. The amount of interest expense related to the amortization of the discount on the ABL Facility for the years ended December 31, 2019 and 2018 was $93,901 and $93,902, respectively. As of December 31, 2019, the ABL Facility borrowing base availability was $9,794,000, of which $4,738,136 principal was outstanding. The outstanding liability as of December 31, 2019 was $4,534,683, net of unamortized debt issuance cost of $203,453.
