Senior Credit Facilities

On May 19, 2016, the Company entered into the second amended and restated credit agreement (the “Second Amended and Restated Credit Agreement”) with new and existing lenders for an aggregate credit facility of $300.0 million, consisting of a $75.0 million, 5-year term loan facility due in quarterly installments of $1.9 million beginning in July 2016 and a $225.0 million, 5-year revolving credit facility (collectively, the “Senior Credit Facilities”). The Senior Credit Facilities mature in May 2021. Quarterly installments due in the next twelve months under the term loan amount to $7.5 million and are classified as a current liability on the consolidated balance sheet. The increase in the amount outstanding under the Company’s revolving credit facility in the six months ended June 30, 2017 was related to additional borrowings to fund the Laser Quantum and ThingMagic acquisitions.

The Company is required to satisfy certain financial and non-financial covenants under the Second Amended and Restated Credit Agreement. The Company was in compliance with these covenants as of June 30, 2017.

Liens

The Company’s obligations under the Senior Credit Facilities are secured on a senior basis by a lien on substantially all of the assets of the Company and certain U.S., U.K. and German subsidiaries as defined in the Second Amended and Restated Credit Agreement and guaranteed by the Company and these subsidiaries. The Second Amended and Restated Credit Agreement also contains customary events of default.

Fair Value of Debt

As of June 30, 2017 and December 31, 2016, the outstanding balance of the Company’s debt approximated its fair value based on current rates available to the Company for debt of the same maturity.
