Borrowing Facilities	Note 7 – Borrowing Facilities As of June 30, 2018, the Company had a $430 million Credit Agreement (the Credit Agreement) with JPMorgan Chase Bank, N.A. as administrative agent and collateral agent (the Administrative Agent), and the financial institutions acting as lenders thereunder from time to time. This Credit Agreement provided for a five-year $200 million revolving credit facility (the Revolving Credit Facility) and a five-year $230 million term loan facility (the Term Loan). The Revolving Credit Facility was available for general corporate purposes, could be drawn in foreign currencies up to an amount equivalent to $20 million, and could be used for letters of credit up to $20 million. The Credit Agreement included an accordion feature, pursuant to which total commitments under the facility could be increased by an additional $150 million, subject to satisfaction of certain conditions. The Term Loan was payable in minimum quarterly principal installments of $4.3 million in 2018, $5.8 million in 2019, and $8.6 million in 2020, with the balance payable on the maturity date. Interest on outstanding borrowings under the Credit Agreement accrued, at our option, at (a) the adjusted London interbank offered rate (LIBOR) plus 1.25% to 2.25%, or (b) the alternative base rate plus 0.25% to 1.25%, and was payable quarterly in arrears. The alternative base rate was equal to the highest of (i) the Administrative Agent’s prime rate, (ii) the federal funds rate plus 0.50% and (iii) the adjusted LIBOR rate plus 1.00%. The margin on the interest rates fluctuated based upon the ratio of the Company’s debt to its consolidated EBITDA. As of June 30, 2018, $148.8 million of the outstanding debt under the Credit Agreement was effectively at a fixed interest rate as a result of a $148.8 million notional interest rate swap contract discussed in Note 16. A commitment fee of 0.30% to 0.40% per annum (based on the debt to EBITDA ratio) on the unused portion of the revolving credit line was payable quarterly in arrears. The Credit Agreement was generally secured by a pledge of (a) all the capital stock of the Company’s domestic subsidiaries and 65% of the capital stock of its directly owned foreign subsidiaries, (b) any debt owed to Benchmark and its subsidiaries and (c) all or substantially all other personal property of Benchmark and its domestic subsidiaries (including, accounts receivable, contract assets, inventory and fixed assets of Benchmark and its domestic subsidiaries), in each case, subject to customary exceptions and limitations. The Credit Agreement contained financial covenants as to debt leverage and interest coverage, and certain customary affirmative and negative covenants, including restrictions on our ability to incur additional debt and liens, pay dividends, repurchase shares, sell assets and merge or consolidate with other persons. Amounts due under the Credit Agreement could be accelerated upon specified events of default, including a failure to pay amounts due, breach of a covenant, material inaccuracy of a representation, or occurrence of bankruptcy or insolvency, subject, in some cases, to cure periods. As of June 30, 2018 and December 31, 2017, the Company was in compliance with all of these covenants and restrictions. As of June 30, 2018, the Company had $198.4 million in borrowings outstanding under the Term Loan facility and $2.8 million in letters of credit outstanding under the Revolving Credit Facility. The Company had $197.2 million available for future borrowings under the Revolving Credit Facility. On July 20, 2018, the Company entered into a $650 million credit agreement (the New Credit Agreement) by and among the Company, certain of its subsidiaries, the lenders party thereto and Bank of America, N.A., as Administrative Agent, Swingline Lender and a L/C Issuer. The New Credit Agreement replaced the Credit Agreement. The New Credit Agreement is comprised of a five-year $500 million revolving credit facility (the New Revolving Credit Facility) and a five-year $150 million term loan facility (the New Term Loan Facility), both with a maturity date of July 20, 2023. A portion of the New Term Loan Facility proceeds were used to (i) refinance all indebtedness and terminate all commitments under the Credit Agreement discussed above and (ii) pay the fees, costs and expenses associated with the foregoing and the negotiation, execution and delivery of the New Credit Agreement. The New Revolving Credit Facility is available for general corporate purposes. The New Credit Agreement includes an accordion feature pursuant to which the Company is permitted to add one or more incremental term loan and/or increase commitments under the New Revolving Credit Facility in an aggregate amount not exceeding $275 million, subject to the satisfaction of certain conditions. The New Credit Agreement contains certain financial covenants as to interest coverage and debt leverage, and certain customary affirmative and negative covenants, including restrictions on our ability to incur additional debt and liens, pay dividends, repurchase shares, sell assets and merge or consolidate with other persons. The Company’s Thailand subsidiary has a multi-purpose credit facility with Kasikornbank Public Company Limited (the Thai Credit Facility) that provides for 350 million Thai baht (approximately $10.6 million) working capital availability. The Thai Credit Facility is secured by land and buildings in Thailand owned by the Company’s Thailand subsidiary. Availability of funds under the Thai Credit Facility is reviewed annually and is currently accessible through October 2018. As of both June 30, 2018 and December 31, 2017, there were no working capital borrowings outstanding under the facility.
