Credit Facilities

On October 26, 2016, the Company established a $20,000 three-year secured revolving line of credit (the “Credit Facility”) with CIBC Bank USA, formerly known as The PrivateBank and Trust Company (“CIBC”). The Credit Facility was subsequently increased to $25,000 in March of 2017 pursuant to a Second Amendment to Loan and Security Agreement and an Amended and Restated Revolving Note. Under the Credit Facility, CIBC advances funds when requested against a borrowing base consisting of up to 85% of the face value of the Company’s eligible A/R, up to 50% of the book value of eligible inventory and up to 50% of the appraised value of eligible machinery, equipment and certain real property up to $10,000. Borrowings under the Credit Facility bear interest at a per annum rate equal to the applicable LIBOR plus a margin ranging from 2.25% to 3.00%, or the applicable base rate plus a margin ranging from 0.00% to 1.00%, both of which are based on the trailing twelve-month EBITDA. The Company also pays an unused facility fee to CIBC equal to 0.50% per annum on the unused portion of the Credit Facility, along with other standard fees. The Credit Facility contains customary representations and warranties. It also contains a requirement that the Company, on a consolidated basis, maintain a Fixed Charge Coverage Ratio Covenant, along with other customary restrictive covenants. The obligations under the Credit Facility are secured by, subject to certain exclusions, (i) a first priority security interest in all accounts receivable, inventory, equipment, cash and investment property, and (ii) a mortgage on the Abilene, Texas tower facility.

On January 29, 2018, the Company executed the Third Amendment to Loan and Security Agreement (the “Third Amendment”), which waived the Company’s non-compliance with the Fixed Charge Coverage Ratio Covenant as of December 31, 2017 and added new minimum EBITDA and capital expenditure covenants through June 30, 2018. The amendment also revised the Fixed Charge Coverage Ratio Covenant to be recalculated for future periods commencing with the quarter ending June 30, 2018.

On May 3, 2018, the Company executed the Fourth Amendment to Loan and Security Agreement (the “Fourth Amendment”), which waived the Company’s non-compliance with the minimum EBITDA covenant through March 31, 2018. The Fourth Amendment, among other changes, amended the minimum EBITDA thresholds for the period ending June 30, 2018 and adjusted the definition of EBITDA to add back certain restructuring expenses.

On October 26, 2018, the Company executed the Fifth Amendment to Loan and Security Agreement which, among other changes, removed the Fixed Charge Coverage Ratio and capital expenditure covenants as of the period ending December 31, 2018 and added minimum EBITDA covenants through June 30, 2019.

On January 16, 2019, the Company executed the Sixth Amendment to Loan and Security Agreement which increased the Company’s capability to issue letters of credit.

On February, 25, 2019, the Company executed an Amended and Restated Loan and Security Agreement (the “Amended and Restated Loan Agreement”), which expanded the Credit Facility to $35,000 and extended the term to February 25, 2022. The Amended and Restated Loan Agreement includes minimum EBITDA covenants through September 30, 2019 and introduces a Fixed Charge Coverage Ratio thereafter. For a more detailed description of the Amended and Restated Loan Agreement refer to Item 9B of this Form 10-K.

As of December 31, 2018, there was $11,000 outstanding under the Credit Facility. The Company had the ability to borrow up to $10,319 under the Credit Facility as of December 31, 2018.
