Debt

Revolving Credit Facility

On October 31, 2014, the Company entered into a five-year senior secured revolving credit facility in the amount of $25.0 million (the “Revolver”) with Wells Fargo Bank, National Association, as lender. Concurrently with the acquisition of FW, the Company amended the Revolver to include FW as a borrower and Loan Party, as defined by the agreement. On November 17, 2015, the Revolver was amended to increase the maximum borrowing capacity to $48.0 million.

The amount of borrowings that may be made under the Revolver is based on a borrowing base comprised of a specified percentage of eligible receivables. If, at any time during the term of the Revolver, the amount of borrowings outstanding under the Revolver exceeds the borrowing base then in effect, the Company is required to repay such borrowings in an amount sufficient to eliminate such excess. The Revolver includes $3.0 million available for letters of credit, $1.0 million of which was available for letters of credit at June 30, 2016.

The Company may borrow funds under the Revolver from time to time, with interest payable monthly at a base rate determined by using the daily three month LIBOR rate, plus an applicable margin of 3.00% to 3.50% depending on the Company’s liquidity as determined on the last day of each calendar month. The Revolver is secured by a first priority lien on substantially all of the assets of the Company and certain of its subsidiaries, subject to certain exceptions and permitted liens. The Revolver includes customary representations and warranties, as well as customary reporting and financial covenants.

There was no outstanding balance on the Revolver at June 30, 2016 or December 31, 2015. Based on the Company’s eligible receivables at June 30, 2016, the Company has available borrowings of approximately $7.8 million. As of June 30, 2016, the Company was in compliance with all financial covenants contained in the credit agreement.

Convertible Senior Notes

On June 10, 2015, the Company issued $120.0 million aggregate principal amount of Convertible Notes. The Company incurred issuance costs of approximately $3.9 million. The Company used a portion of the proceeds from the offering to finance its acquisition of Ctrack, to pay fees and expenses related to the acquisition, and for general corporate purposes.

The Convertible Notes are governed by the terms of an indenture, dated June 10, 2015, entered into between the Company, as issuer, and Wilmington Trust, National Association, as trustee. The Convertible Notes are senior unsecured obligations and bear interest at a rate of 5.50% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2015. The Convertible Notes will mature on June 15, 2020, unless earlier repurchased or converted. The Convertible Notes will be convertible into cash, shares of the Company’s common stock, or a combination thereof, at the election of the Company, at an initial conversion price of $5.00 per share of the Company’s common stock.
