Revolving Credit Facility

On November 2, 2007, the Company entered into an asset-based credit facility, which permits borrowing up to a maximum level of $100,000. The Company entered into an Amended and Restated Credit and Security Agreement and a Second Amended and Restated Credit and Security Agreement on September 20, 2010 and December 1, 2011, respectively.

On September 12, 2014, the Company entered into a Third Amended and Restated Credit Agreement (the “Amended Agreement” or “Credit Facility”). The Amended Agreement provides for a $300,000 revolving credit facility, which replaced the Company’s existing $100,000 asset-based credit facility and includes a letter of credit subfacility, swing line subfacility and multicurrency subfacility. The Amended Agreement also has an accordion feature which allows the Company to increase the availability by up to $80,000 upon the satisfaction of certain conditions. The Amended Agreement extended the termination date to September 12, 2019 from December 1, 2016. On March 26, 2015, the Company entered into Amendment No. 1 to the Amended Agreement which modified the definition of Consolidated EBITDA to allow for the add back of cash premiums and other non-cash charges related to the amendment and restatement of the Amended Agreement and the early extinguishment of the Company’s 9.5% Senior Secured Notes. Consolidated EBITDA is used in computing the Company’s leverage ratio and interest coverage ratio which are covenants within the Amended Agreement. On February 23, 2016, the Company entered into Amendment No. 2 to the Amended Agreement which amended and waived any default or potential defaults with respect to the pledging as collateral additional shares issued by a wholly owned subsidiary and newly issued shares associated with the formation of a new subsidiary. On August 12, 2016, the Company entered into Amendment No. 3 (the “Amendment”) to the Amended Agreement which extended of the expiration date of the Agreement by two years to September 12, 2021, increased the borrowing sub-limit for the Company’s foreign subsidiaries by $30,000 to $80,000, increased the basket of permitted loans and investments in foreign subsidiaries by $5,000 to $30,000, and provided additional flexibility to the Company for certain permitted corporate transactions involving its foreign subsidiaries as defined in the Agreement. As a result of Amendment No. 3, the Company capitalized deferred financing costs of $339, which will be amortized over the remaining term of the Credit Facility. On January 30, 2017, the Company entered into Consent and Amendment No. 4 to the Amended Agreement which amended certain definitions, schedules and exhibits of the Credit Facility, consented to a Dutch Reorganization, and consented to the Orlaco acquisition. As a result of Amendment No. 4, the Company capitalized deferred financing costs of $47, which will be amortized over the remaining term of the Credit Facility.

Borrowings under the Amended Agreement bear interest at either the Base Rate, as defined, or the LIBOR Rate, at the Company’s option, plus the applicable margin as set forth in the Amended Agreement. The Company is also subject to a commitment fee ranging from 0.20% to 0.35% based on the Company’s leverage ratio. The Amended Agreement requires the Company to maintain a maximum leverage ratio of 3.00 to 1.00, and a minimum interest coverage ratio of 3.50 to 1.00 and places a maximum annual limit on capital expenditures. The Amended Agreement also contains other affirmative and negative covenants and events of default that are customary for credit arrangements of this type including covenants which place restrictions and/or limitations on the Company’s ability to borrow money, make capital expenditures and pay dividends.

Borrowings outstanding on the Credit Facility increased from $67,000 at December 31, 2016 to $141,000 at March 31, 2017 because the Company borrowed under the Credit Facility in order to fund the Orlaco acquisition described in Note 3.

The Company also has outstanding letters of credit of $3,367 and $3,399 at March 31, 2017 and December 31, 2016, respectively.

The Company was in compliance with all Credit Facility covenants at March 31, 2017 and December 31, 2016.
