﻿ 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 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 to the Amended Agreement, 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 to the Amended Agreement, the Company capitalized deferred financing costs of $61, which will be amortized over the remaining term of the Credit Facility. On September 11, 2018, the Company entered into Amendment No. 5 to the Amended Agreement which extended financial accommodations to permit the Company to invest in certain funds in an amount that does not exceed $10,000. ﻿ On October 26, 2018, the Company entered into Consent and Amendment No. 6 to the Amended Agreement which amended certain definitions, sections and schedules of the Credit Facility and consented to realignment of certain foreign subsidiaries, and permits the Company to repurchase the Company’s outstanding common shares in an amount that does not exceed $50,000. ﻿ 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 were $101,000 and $121,000 at September 30, 2018 and December 31, 2017, respectively. Borrowings decreased under the Credit Facility due to voluntary principal repayments. ﻿ The Company was in compliance with all Credit Facility covenants at September 30, 2018 and December 31, 2017. ﻿ The Company also has outstanding letters of credit of $2,008 at September 30, 2018 and December 31, 2017. ﻿ Debt PST maintains several short-term obligations and long-term notes used for working capital purposes which have fixed or variable interest rates. The weighted-average interest rates of short term and long-term debt of PST at September 30, 2018 was 11.26% and 8.65%. Depending on the specific note, interest is payable either monthly or annually. Principal repayments on PST debt at September 30, 2018 are as follows: $1,808 from October 2018 through September 2019, $330 from October 2019 through December 2019, $465 in 2020 and $423 in 2021. PST was in compliance with all debt covenants at September 30, 2018 and December 31, 2017. ﻿ The Company's wholly-owned subsidiary located in Stockholm, Sweden, has an overdraft credit line which allows overdrafts on the subsidiary's bank account up to a maximum level of 20,000 Swedish krona, or $2,250 and $2,439, at September 30, 2018 and December 31, 2017, respectively. At September 30, 2018 and December 31, 2017, there was no balance outstanding on this overdraft credit line.
