Senior Notes In September 2017, the Company issued $300.0 million aggregate principal amount of 4.875% senior notes due October 15, 2025 ("Senior Notes") at par value in a private placement under Rule 144A of the Securities Act of 1933, as amended. The Senior Notes accrue interest at a rate of 4.875% per annum, payable semi-annually in arrears on April 15 and October 15, commencing on April 15, 2018. The payment of principal and interest is jointly and severally guaranteed, on a senior unsecured basis, by certain subsidiaries of the Company (each a "Guarantor" and collectively the "Guarantors"). The Senior Notes are pari passu in right of payment with all existing and future senior indebtedness and subordinated to all existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. Prior to October 15, 2020, the Company may redeem up to 35% of the principal amount of the Senior Notes at a redemption price of 104.875% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, with the net cash proceeds of one or more equity offerings provided that each such redemption occurs within 90 days of the date of closing of each such equity offering. In addition, the Company may redeem all or part of the Senior Notes at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, plus a "make whole" premium. On or after October 15, 2020, the Company may redeem all or part of the Senior Notes at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, to the redemption date, if redeemed during the twelve-month period beginning on October 15 of the years indicated below:
Year |  | Percentage
2020 |  | 102.438 | %
2021 |  | 101.219 | %
2022 and thereafter |  | 100.000 | %
Credit Agreement The Company is a party to a credit agreement ("Credit Agreement") consisting of a $300.0 million senior secured revolving credit facility, which permits borrowings denominated in specific foreign currencies, subject to a $125.0 million sub limit, matures on September 20, 2022 and is subject to interest at London Interbank Offered Rate ("LIBOR") plus 1.50%. The interest rate spread is based upon the leverage ratio, as defined, as of the most recent determination date. The Credit Agreement also provides incremental revolving credit facility commitments in an amount not to exceed the greater of $200.0 million and an amount such that, after giving effect to such incremental commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 3.00 to 1.00. The terms and conditions of any incremental revolving credit facility commitments must be no more favorable than the existing credit facility. The Company's revolving credit facility allows for the issuance of letters of credit, not to exceed $40.0 million in aggregate. At June 30, 2018, the Company had no amounts outstanding under its revolving credit facility and had approximately $285.9 million potentially available after giving effect to approximately $14.1 million of letters of credit issued and outstanding. At December 31, 2017, the Company had approximately $10.8 million outstanding under its revolving credit facility and had approximately $274.3 million potentially available after giving effect to approximately $14.9 million of letters of credit issued and outstanding. However, including availability under its former accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had approximately $285.9 million and $332.1 million at June 30, 2018 and December 31, 2017, respectively, of borrowing capacity available for general corporate purposes. The debt under the Credit Agreement is an obligation of the Company and certain of its domestic subsidiaries and is secured by substantially all of the assets of such parties. Borrowings under the $125.0 million (equivalent) foreign currency sub limit of the $300.0 million senior secured revolving credit facility are secured by a cross-guarantee amongst, and a pledge of the assets of, the foreign subsidiary borrowers that are a party to the agreement. The Credit Agreement also contains various negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including the ability to, subject to certain exceptions and limitations, incur debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, assets dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of the Credit Agreement also require the Company and its restricted subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum total net leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility, less the aggregate amount of certain unrestricted cash and unrestricted permitted investments, as defined, over consolidated EBITDA, as defined), a maximum senior secured net leverage ratio (total consolidated senior secured indebtedness, less the aggregate amount of certain unrestricted cash and unrestricted permitted investments, as defined, over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over the sum of consolidated cash interest expense, as defined, and preferred dividends, as defined). At June 30, 2018, the Company was in compliance with its financial covenants contained in the Credit Agreement. Receivables Facility In March 2018, the Company terminated its accounts receivable facility previously utilized through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary. The facility was used to sell trade accounts receivable of substantially all of the Company's domestic business operations. Under this facility, TSPC, from time to time, could sell an undivided fractional ownership interest in the pool of receivables up to $75.0 million to a third-party multi-seller receivables funding company. The cost of funds under this facility consisted of a 1-month LIBOR-based rate plus a usage fee of 1.00% and a fee on the unused portion of the facility of 0.35%. At December 31, 2017, the Company had no amounts outstanding under the facility and approximately $57.8 million available but not utilized. Aggregate costs incurred under the facility were approximately $0.3 million for the three months ended June 30, 2017, and $0.1 million and $0.6 million for the six months ended June 30, 2018 and 2017, respectively, and are included in interest expense in the accompanying consolidated statement of income. Fair Value of Debt The valuations of the Senior Notes and revolving credit facility were determined based on Level 2 inputs under the fair value hierarchy, as defined. The carrying amounts and fair values were as follows (dollars in thousands):
|  | June 30, 2018 |  | December 31, 2017
