In April 2017, we entered into the Third Amended and Restated Loan and Security Agreement with Squadron providing us with (i) a term loan in the amount of $18,400, bearing interest at a per annum rate of 10%, and (ii) a term loan in the amount of $16,000, bearing interest at a per annum rate of 11%. Each of the term loans was to have matured on March 31, 2019. In addition, the agreement provided for a $1,000 extension fee payable in three annual installments. The extension fee was recorded in full upon closing as a deferred financing cost within long-term debt with affiliate, net of current portion, and was to be recognized ratably over the term of the agreement as deferred financing charges within interest expense on the consolidated statements of operations assuming an IPO did not happen.

Effective December 31, 2017, we entered into a Fourth Amended and Restated Loan and Security Agreement, or the Loan Agreement, with Squadron. Pursuant to the Loan Agreement, a majority of the term loan amounts under the previous agreement with Squadron were consolidated into a $20,000 term note, or the Term Note A, and a $15,000 revolving credit facility was established. Also, $667 of the extension fee was canceled as of the completion of our IPO in October 2017. Both facilities include interest only payments and have interest rates equal to the greater of (a) three month LIBOR plus 8.61% and (b) 10%. The Loan Agreement also extended the maturity date to January 31, 2023.

In order to finance a portion of the cash consideration for the acquisition of Vilex and Orthex, the Company entered into a first Amendment, or the Amendment, to the Loan Agreement (as so amended, the "Amended Loan Agreement"), with Squadron. The Amended Loan Agreement provides for a new $30,000 term loan facility, represented by a Term Note B, in addition to the existing $20,000 Term Note A and $15,000 revolving credit facility. Similar to the other facilities under the Amended Loan Agreement, the Term Note B is subject to interest only payments at an interest rate equal to the greater of (a) three month LIBOR plus 8.61%, and (b) 10.00%. The maturity date for the Term Note B is the earliest of: (i) the date on which any persons acquire (x) capital stock of the Company possessing the voting power to elect a majority of the Company's Board of Directors (whether by merger, consolidation, reorganization, combination, sale or transfer), or (y) all or substantially all of the Company's assets, determined on a consolidated basis; (ii) the date on which the Company sells its equity interest in, or all or substantially all of the assets of, Vilex; and (iii) May 31, 2020. Until such time that the Term Note B and all accrued interest thereon has been paid in full, no borrowings under the revolving loan facility are permitted.

As provided in the Amendment, Orthex has become a "Borrower" under the Amended Loan Agreement and, as such, granted to Squadron a security interest in all of its personal property as collateral for all borrowings under the Amended Loan Agreement. In connection with the Amendment, the Company granted a security interest in (a) the units of membership interest in Orthex held by the Company, and (b) the shares of stock of Vilex held by the Company, as collateral for borrowings under the Amended Loan Agreement. Borrowings under the Amended Loan Agreement are secured by substantially all of the Company's assets and are unconditionally guaranteed by each of its subsidiaries with the exception of Vilex.

The fair value of our notes payable to Squadron were estimated based on prices for the same or similar issues and the current interest rates offered for the debt of the same remaining maturities, which are considered level 2 inputs in accordance with ASC Topic 820, “Fair Value Measurements and Disclosures.” At June 30, 2019, the fair value approximated the carrying value.

In connection with the purchase of our office and warehouse space in Warsaw, Indiana in August 2013, we entered into a mortgage note payable to Tawani Enterprises Inc., an affiliate of Squadron. Pursuant to the terms of the mortgage note, we pay Tawani Enterprises Inc. monthly principal and interest installments of $16 with interest compounded at 5% until maturity in 2028, at which time a final payment of remaining principal and interest is due. The mortgage is secured by the related real estate and building. At December 31, 2018, the mortgage balance was $1,418 of which current principal due of $118 was included in current portion of long-term debt. At June 30, 2019, the mortgage balance was $1,359 of which current principal due of $121 was included in current portion of long-term debt.
