Credit Agreement

The Company is party to a credit agreement (the "Credit Agreement"), consisting of a $500.0 million senior secured revolving credit facility, which permits borrowings denominated in specific foreign currencies ("Foreign Currency Loans"), subject to a $75.0 million sub limit, which matures on June 30, 2020 and is subject to interest at London Interbank Offered Rates ("LIBOR") plus 1.75%, and a $275.0 million senior secured term loan A facility ("Term Loan A Facility"), which matures on June 30, 2020 and is subject to interest at LIBOR plus 1.75%. 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 term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300.0 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 2.50 to 1.00. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility.

The Company may be required to prepay a portion of its Term Loan A Facility in an amount equal to a percentage of the Company's excess cash flow, as defined, with such percentage based on the Company's leverage ratio, as defined. As of March 31, 2016, no amounts are due under this provision.

The Company is also able to issue letters of credit, not to exceed $40.0 million in aggregate, against its revolving credit facility commitments. At March 31, 2016 and December 31, 2015, the Company had letters of credit of approximately $18.1 million and $21.6 million, respectively, issued and outstanding.

At March 31, 2016, the Company had approximately $121.2 million outstanding under its revolving credit facility and had approximately $360.7 million potentially available after giving effect to approximately $18.1 million of letters of credit issued and outstanding. At December 31, 2015, the Company had approximately $100.3 million outstanding under its revolving credit facility and had approximately $378.1 million potentially available after giving effect to approximately $21.6 million of letters of credit issued and outstanding. However, including availability under its accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had approximately $66.8 million and $107.4 million at March 31, 2016 and December 31, 2015, respectively, of borrowing capacity available for general corporate purposes.

Principal payments required under the Credit Agreement for the Term Loan A Facility are approximately $3.4 million due each fiscal quarter from December 2015 through September 2018 and approximately $5.2 million due each fiscal quarter from December 2018 through March 2020, with final payment of approximately $202.8 million due on June 30, 2020.

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 $75.0 million foreign currency sub limit of the $500.0 million senior secured revolving credit facility are secured by 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 restrictions on the incurrence of 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 subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). At March 31, 2016, the Company was in compliance with its financial covenants contained in the Credit Agreement.

As of March 31, 2016 and December 31, 2015, the Company's Term Loan A Facility traded at approximately 99.6% of par value and the Company's revolving credit facility traded at approximately 99.3% of par value. The valuations of the Credit Agreement were determined based on Level 2 inputs under the fair value hierarchy, as defined.

Receivables Facility

The Company is party to an accounts receivable facility through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all of the Company's domestic business operations. Under this facility, TSPC, from time to time, may 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 net amount financed under the facility is less than the face amount of accounts receivable by an amount that approximates the purchaser's financing costs. 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% as of March 31, 2016 and 2015.

The Company had approximately $54.0 million and $53.6 million outstanding under the facility as of March 31, 2016 and December 31, 2015, respectively. No amounts were available but not utilized as of March 31, 2016. As of December 31, 2015, approximately $7.1 million was available but not utilized. Aggregate costs incurred under the facility were approximately $0.2 million for both the three months ended March 31, 2016 and 2015, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on June 30, 2020.

The cost of funds fees incurred are determined by calculating the estimated present value of the receivables sold compared to their carrying amount. The estimated present value factor is based on historical collection experience and a discount rate based on a 1-month LIBOR-based rate plus the usage fee discussed above and is computed in accordance with the terms of the agreement. As of March 31, 2016, the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.8 months and an average discount rate of 1.9%.
