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 (the “Amendment”) 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. ﻿ Borrowings under the Amended Agreement will 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 agreement governing our Credit Facility 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 at both March 31, 2016 and December 31, 2015 were $100,000. ﻿ The Company was in compliance with all credit facility covenants at March 31, 2016 and December 31, 2015. Debt PST maintains several short-term obligations and long-term notes used for working capital purposes which have fixed annual interest rates. The weighted-average interest rates of short-term and long-term debt of PST at March 31, 2016 were 16.0% and 7.3%, respectively. Depending on the specific note, interest is payable either monthly or annually. Principal payments on PST debt at March 31, 2016 are as follows: $16,503 from April 2016 through March 2017, $1,400 from April 2017 through December 2017, $1,082 in 2018, $1,058 in 2019, $363 in 2020 and $303 in 2021. The Company was in compliance with all debt covenants at March 31, 2016 and December 31, 2015. ﻿ 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 $2,464 and $2,369, at March 31, 2016 and December 31, 2015, respectively. At March 31, 2016 and December 31, 2015, there was no balance outstanding on this bank account.
