| Long-term Debt | 17. Long-term Debt: The summary of long-term debt is as follows: December 31, 2019 2018 Term Loan Facility $ 947,497 $ 1,157,498 6.75% Senior Secured Notes due 2022 625,000 625,000 5.75% Senior Unsecured Notes due 2025 295,000 300,000 ABL Facility — — Other 64,629 65,925 Total debt 1,932,126 2,148,423 Original issue discount (13,434 ) (18,584 ) Deferred financing costs (11,730 ) (15,882 ) Total debt, net of original issue discount and deferred financing costs 1,906,962 2,113,957 Less: current portion (7,766 ) (7,237 ) Total long-term debt, excluding current portion $ 1,899,196 $ 2,106,720 Senior Secured Credit Facilities On May 4, 2016, the Company entered into senior secured credit facilities (collectively, the “2016 Senior Secured Credit Facilities”) comprised of a $1,200,000 term loan facility, which consisted of a $900,000 U.S. dollar-denominated tranche and a $300,000 Euro-denominated (or €265,000 ) tranche (the “2016 Term Loan Facility”), and a $200,000 asset-based revolving credit facility (the “ABL Facility”). On February 8, 2018 (the “Third Amendment Closing Date”), PQ Corporation (the “Borrower”), an indirect, wholly owned subsidiary of the Company, refinanced its existing U.S. Dollar and Euro denominated senior secured term loan facilities with a new $1,267,000 senior secured term loan facility (the “Term Loan Facility”) by entering into the Third Amendment Agreement to the 2016 Term Loan Facility (the “Third Amendment”), which amended and restated the Term Loan Credit Agreement dated as of May 4, 2016, among the Borrower, CPQ Midco I Corporation, Credit Suisse AG, Cayman Island Branch, as administrative agent and collateral agent, and the lenders and the other parties party thereto from time to time (as amended prior to the Third Amendment, the “Existing Credit Agreement” and as amended and restated by the Amendment, the “New Credit Agreement”). As of December 31, 2019 , the Term Loan Facility accrued interest at a floating rate of LIBOR plus 2.50% per annum and was scheduled to mature in February 2025. The Term Loan Facility requires scheduled quarterly amortization payments, each equal to 0.25% of the original principal amount of the loans under the Term Loan Facility. On the Third Amendment Closing Date, the Company also entered into multiple cross currency swap arrangements to hedge foreign currency risk. The swaps were designed to enable the Company to effectively convert a portion of its fixed-rate U.S. dollar denominated debt obligations into approximately €280,000 . The swaps were to mature in February 2023. In October 2019, the Company settled all of its cross-currency interest rate swap arrangements (the “February 2018 swaps”) and concurrently entered into new cross-currency interest rate swap arrangements (the “October 2019 swaps”) with the same notional amount of €280,000 equivalent ( $313,656 as of December 31, 2019 ) and same maturity of February 2023. Consistent with the February 2018 swaps, the October 2019 swaps are designed to enable the Company to effectively convert a portion of its fixed-rate U.S. dollar-denominated debt obligations under the Term Loan Facility into a Euro-denominated equivalent. The October 2019 swaps have been designated and qualify as net investment hedges of the Company’s foreign currency exchange rate exposure on the net investments of certain of its Euro-denominated subsidiaries. The settlement of the February 2018 swaps resulted in cash proceeds to the Company of $38,070 , which the Company used for additional debt repayment on the Company’s Term Loan Facility. The Company may at any time or from time to time voluntarily prepay loans under the Term Loan Facility in whole or in part without premium or penalty. The Term Loan Facility requires mandatory prepayments from (i) 50% of “Excess Cash Flow” (as defined in the New Credit Agreement) on an annual basis with step downs to lower percentages based on the Borrower’s leverage ratio, if applicable, (ii) net cash proceeds from the issuance or incurrence of certain indebtedness and (iii) net cash proceeds received from certain non-ordinary course disposition of assets and casualty events to the extent such net cash proceeds were not reinvested in the Company’s business within a certain specified time period. Prepayments are applied to remaining amortization installments in direct order of maturity. The remaining principal balance of the term loans are due upon maturity. In addition, the New Credit Agreement contains customary affirmative and negative covenants and events of default, all of which are substantially the same as under the Existing Credit Agreement. The Borrower and certain Canadian and European subsidiaries of the Borrower also have a $200,000 asset-based revolving credit facility (the “ABL Facility”) which provides for $150,000 in U.S. available borrowings, up to $10,000 in Canadian available borrowings and up to $40,000 of European available borrowings. Borrowings under the ABL Facility bear interest at a rate equal to the LIBOR rate or the base rate elected by the Company at the time of the borrowing plus a margin of between 1.50% - 2.00% or 0.50% - 1.00% , respectively, depending on availability under the ABL Facility. In addition, there is an annual commitment fee equal to 0.375% , with a step-down to 0.25% based on the average usage of the revolving credit borrowings available. As of December 31, 2019 , there were no revolving credit borrowings under the ABL Facility. Revolving credit borrowings are payable at the option of the Company throughout the term of the ABL Facility with the balance due May 4, 2021. The Company has the ability to request letters of credit under the ABL Facility. The Company had $20,506 of letters of credit outstanding as of December 31, 2019 , which reduce available borrowings under the ABL Facility by such amounts. The Term Loan Facility is guaranteed by CPQ Midco I Corporation, a subsidiary of the Company and the direct parent of the Borrower (“Holdings”) and substantially all of the Borrower’s wholly owned U.S. subsidiaries. The obligations under the Term Facility are secured (i) by a first-priority security interest in, among other things, a pledge substantially all of the Borrower’s and the guarantors’ assets (other than collateral securing the ABL Facility on a first-priority basis) and (ii) by a second-priority security interest in receivables, inventory, deposit accounts and other collateral of the Borrower and the U.S. subsidiary guarantors securing the ABL Facility. The liens securing the Term Loan Facility and the guarantees are pari passu with the liens securing the Senior Secured Notes subject to the pari passu intercreditor agreement. The obligations of the Borrower under the ABL Facility are guaranteed by Holdings and the same U.S. subsidiary guarantors that guarantee the Term Loan Facility, the obligations of the Canadian Borrowers under the ABL Facility are guaranteed by certain other Canadian subsidiaries of the Borrower and the obligations of the European Borrowers under the ABL Facility are guaranteed by certain other European subsidiaries of the Borrower. The obligations of the borrowers and guarantors under the ABL Facility are secured (i) by a first-priority security interest in, among other things, substantially all of their receivables, inventory, deposit accounts and other collateral securing the ABL Facility on a first-priority basis and (ii) by a second-priority security interest in the property and assets of Holdings, the Borrower and the U.S. subsidiary guarantors that secure the Term Loan Facility. In addition, the ABL Facility is secured by the equity interests in, and substantially all of the assets of, certain foreign guarantors in connection with the Canadian dollar-denominated and Euro-denominated availability. The Term Loan Facility and the ABL Facility contain various non-financial restrictive covenants. Each limits the ability of PQ Corporation and its restricted subsidiaries to incur certain indebtedness or liens, merge, consolidate or liquidate, dispose of certain property, make investments or declare or pay dividends, make optional payments, modify certain debt instruments, enter into certain transactions with affiliates, enter into certain sales and leasebacks, and certain other non-financial restrictive covenants. The ABL Facility also contains one financial covenant which applies when minimum availability under the ABL Facility exceeds a certain threshold. During such time, the Company is required to maintain a fixed-charge coverage ratio of at least 1 .0 to 1.0. The Company is in compliance with all debt covenants as of December 31, 2019 and 2018 , respectively. During the year ended December 31, 2018 , the Company prepaid $100,000 of outstanding principal balance on the Term Loan Facility. The Company wrote off $559 of previously unamortized deferred financing costs and original issue discount of $1,313 as debt extinguishment costs.

The NMTC program, which is administered by the United States Treasury Department, requires certain balance sheet commitments. The 2013 NMTC Agreement will provide the Company with certain monetary benefits as an offset to specifically identified capital expenditures. The 2013 NMTC Agreement requires that certain commitments and covenants be maintained over a period of seven years in order to legally recognize the benefit. Chase agreed to contribute $6,634 and an additional $15,632 in funds lent to Chase by Potters Holdings II, L.P. to TX CDE. TX CDE, in turn, lent $21,000 in the form of $5,368 and $15,632 of notes to Potters, which used the proceeds to finance the expansion of Potters’ manufacturing facility in Paris, Texas. The capital expenditures associated with the 2013 NMTC Agreement were completed in 2014. The $21,000 of debt related to the 2013 NMTC was assumed as part of the former business combination and was outstanding as of December 31, 2019 and 2018 . On May 17, 2016, Potters entered into a NMTC financing arrangement with U.S. Bank N.A. and several of its affiliates (“USB”) and MRC XX LLC, an affiliate of Midwest Renewable Capital, LLC (“MRC”), to fund the expansion of Potters’ manufacturing facility in Augusta, Georgia (the “May 2016 NMTC Agreement”). The May 2016 NMTC Agreement provides the Company with certain monetary benefits as an offset to specifically identified capital expenditures. The May 2016 NMTC Agreement requires that certain commitments and covenants be maintained over a period of seven years in order to legally recognize the benefit. USB agreed to contribute $3,732 and an additional $7,822 in funds lent to USB by Potters Holdings II, L.P. to MRC. MRC, in turn, lent $11,000 in the form of $7,823 , $1,311 and $1,866 of notes to Potters, which used the proceeds to finance the expansion of Potters’ manufacturing facility in Augusta, Georgia. The $11,000 was outstanding as of December 31, 2019 . The capital expenditures associated with the May 2016 NMTC Agreement were completed in 2017. On December 29, 2016, Potters entered into a second NMTC financing arrangement with USB and MRC whereby USB agreed to contribute $3,815 and an additional $7,775 in funds lent to USB by Potters Holdings II, L.P. to MRC. MRC, in turn, lent $11,000 in the form of $7,775 , $1,402 and $1,823 of notes to Potters, which will use the proceeds as working capital for another expansion of Potters’ manufacturing facility in Paris, Texas (the “December 2016 NMTC Agreement”). The $11,000 was outstanding as of December 31, 2019 and 2018 . Potters expended the proceeds of the notes as working capital in 2017. On June 22, 2017, Potters, entered into a NMTC financing arrangement with U.S. Bank N.A. (“USB”), one of USB’s affiliates (“USB Investment Fund”) and Business Conduit No. 28, LLC, an affiliate of Community Reinvestment Fund, Inc. (“CRF”). USB contributed $3,054 to USB Investment Fund, and Potters Leveraged Lender LLC, an indirect subsidiary of the Company, lent USB Investment Fund $6,221 . USB Investment Fund then contributed $9,000 to CRF, which in turn lent $8,820 to Potters pursuant to a credit agreement (the “June 2017 NMTC Agreement”). Potters used the $8,820 in proceeds to acquire equipment for the expansion of Potters’ manufacturing facility in Paris, Texas. The June 2017 NMTC Agreement provides the Company with certain monetary benefits as an offset to specifically identified capital expenditures. The June 2017 NMTC Agreement requires that certain commitments and covenants are maintained over a period of seven years in order to legally recognize the benefit. The $8,820 was outstanding as of December 31, 2019 and 2018 . The capital expenditures associated with the June 2017 NMTC Agreement were completed in 2018. In connection with the aforementioned NMTC financing arrangements, the Company provided indemnifications related to its actions or inactions which cause either a NMTC disallowance or recapture event. In the event that the Company causes either a recapture or disallowance of the tax credits expected to be generated under this program, then the Company will be required to repay the disallowed or recaptured tax credits plus an amount sufficient to pay the taxes on such repayment to the counterparty of the agreement. This indemnification covers the Company’s actions and inactions prior the end of the seven-year term of each agreement. The maximum potential amount of future payments under this indemnification is approximately $24,649 . The Company currently believes that the likelihood of a required payment under this indemnification is remote. Subsidiary Credit Agreement On June 12, 2017, the Company acquired Sovitec and assumed its obligations to Belfius Bank NV (“Belfius”). On June 8, 2017, Sovitec entered into a credit agreement with Belfius governing a €14,500 credit line which is divided into four tranches.

A capital expenditure line of credit (“CAPEX line”) of €1,000 was issued under the form of straight loans with a maturity date of September 30, 2021. Tranche A is subject to principal payments of €750 made on September 30 and December 31 of each year. Borrowings under the credit agreement bear rates based on Sovitec’s ratio of net debt to Normalized EBITDA. Normalized EBITDA is defined as the Sovitec consolidated operating profit before non-recurring items (i.e. items non-related to normal operations of the last twelve month period and provided an acceptable description of the one-off character of those items is given) and before taxation, depreciation and amortization. Interest rate margins are subject to being reset on June 30 of each year. Interest rates reset based on three net debt to Normalized EBITDA ratio ranges of less than 2, between 2 and 3 or greater than 3. Rates for each tranche of debt reset based on 1 to 9 month EURIBOR rates (not lower than zero) plus a margin that can range between 1.10% to 1.55% for Tranche A, 1.85% to 2.15% for Tranche B, 0.90% and 1.20% for Working Capital and 1.25% and 1.80% for the CAPEX line. As of December 31, 2019 , the interest rate on the credit agreements are as follows: Tranche A, 1.10% , Tranche B, 1.85% , Working Capital, 0.90% and CAPEX 1.25% .

Loans and guarantees under the credit agreement are secured by (1) a first priority security interest on the Sovitec properties located Fleurus, Belgium and Florange, France and (2) 100% of the nominative shares in Sovitec’s wholly owned parent company, Sovitec International B.V. The credit agreement contains various non-financial and financial covenants. Each limits the ability of Sovitec and its restricted subsidiaries to incur certain indebtedness or liens, merge, consolidated or liquidate, dispose of certain property, make investments or declare or pay dividends. The credit agreement also contains one financial covenant which requires maintaining a maximum net debt/EBITDA ratio of 3 :1 during the first three years of the agreement and afterwards a maximum 2.5 :1 ratio. The Company is in compliance with all debt covenants as of December 31, 2019 . Notes Payable The Company also has several note payable agreements denominated in Japanese Yen which enables the Company to borrow up to a total of 260,000 Japanese Yen, or $2,358 . Borrowings bear interest at either TIBOR (“Tokyo Interbank Offered Rate”) plus a margin or the short-term prime rate. The terms of the agreements vary and are renewable upon expiration of the term with the balances due in 2020 . Borrowings under the agreement are payable at the option of the Company throughout the term of the agreements. Borrowings outstanding under these agreements were $2,387 and $2,358 as of December 31, 2019 and 2018 , respectively. Certain of the Company’s foreign subsidiaries maintain other note payable agreements. These agreements are not further described as they are not significant to the consolidated financial statements.
