NOTE 3. FINANCING ARRANGEMENTS

We have a credit agreement with Bank of America which was entered into on June 15, 2017 and provides for a line of credit arrangement of $16 million that expires on June 15, 2022. The credit arrangement also has a $5 million real estate term note outstanding with a maturity date of June 15, 2022. The Bank of America credit agreement replaces our previous credit agreement with Wells Fargo Bank which terminated on June 20, 2017 and resulted in a loss on the extinguishment of debt of $174,834 primarily related to legal and terminations fees.

Under the Bank of America credit agreement, both the line of credit and real estate term notes are subject to variations in the LIBOR rate. Our line of credit bears interest at the combined weighted-average interest rate of 3.74% as of December 31, 2017. We had borrowings on our line of credit of $8,502,853 and $7,315,262 outstanding as of December 31, 2017 and 2016, respectively. There are no subjective acceleration clauses under the credit agreement that would accelerate the maturity of our outstanding borrowings.

The line of credit and real estate term notes with Bank of America contain certain covenants which, among other things, require us to adhere to regular reporting requirements, abide by annual shareholder dividend limitations, maintain certain financial performance, and limit the amount of annual capital expenditures. The availability under our line is subject to borrowing base requirements, and advances are at the discretion of the lender. The line of credit is secured by substantially all of our assets.

The Bank of America credit agreement provides for, among other things, a fixed charge coverage ratio of not less than (i) 1.0 to 1.0 for each period of four fiscal quarters, commencing with the period of four fiscal quarters ending December 31, 2018.

The availability under the line is subject to borrowing base requirements, and advances are at the discretion of the lender. At December 31, 2017 and 2016, we had unused availability under our line of credit of $4,231,000 and $5,710,602, respectively, supported by our borrowing base. The line is secured by substantially all of our assets.

Our credit agreement with Wells Fargo Bank, which terminated on June 20, 2017, as amended, provided for a line of credit arrangement of $15.0 million through May 31, 2018, of which $7,315,262 was outstanding at December 31, 2016. The credit arrangement also had a $3.5 million of real estate term notes with a maturity in 2027, an equipment loan for $2.7 million and a term loan facility of up to $1.0 million for capital expenditures, both with maturity dates of May 31, 2018. As of December 31, 2016, there was $684,000 outstanding against the $1.0 million capital term note.

Under the credit agreement, both the line of credit and real estate term notes were subject to variations in the LIBOR rate, of which interest rates were 3.25%-3.75% at December 31, 2016. The line of credit required a lock box arrangement; however there were no subjective acceleration clauses that would accelerate the maturity of our outstanding borrowings.

As amended, the Wells Fargo credit agreement contained certain covenants which, among other things, required us to adhere to regular reporting requirements, abide by annual shareholder dividend limitations, maintain certain financial performance, limit the amount of annual capital expenditures and fixed charge coverage ratio requirement. The availability under the Wells Fargo Bank line was subject to borrowing base requirements. At December 31, 2016, we have net unused availability under our line of credit of approximately $5.7 million. The line was secured by substantially all of our assets.

As part of the July 1, 2015 Devicix acquisition we entered into two unsecured subordinated promissory notes payable to the seller in the principal amounts of $1.0 million and $1.3 million. The $1.0 million promissory note has a four-year term, bearing interest at 4% per annum, requiring monthly principal and interest payments of $22,579 and is subject to offsets if certain revenue levels are not met. The $1.3 million promissory note has a four-year term and bears interest at 4% per annum, requiring monthly principal and interest payments of $29,353 and is not subject to offset.
