Senior Revolving Credit Facility In December 2011, the Company entered into a revolving credit facility (the “Facility”), pursuant to an Amended and Restated Credit Agreement (as amended, the “Credit Agreement”), with the lenders named therein and PNC Bank, National Association (“PNC”), as a lender and administrative agent for the lenders. The Credit Agreement, as amended, contains certain covenants that restrict certain actions by the Company, including (i) payment of dividends and limitations on: (ii) stock repurchases to $50.0 million per year, subject to certain restrictions; and (iii) capital expenditures and commitments to $50.0 million per year. The Credit Agreement also permits intercompany loans of up to $375.0 million and requires the Company to meet certain financial covenant ratios that become effective when average outstanding borrowings under the Credit Agreement, including letters of credit, exceed the lesser of $40.0 million or 40% of the total commitments during certain periods or if the outstanding borrowings exceed the borrowing base. If the financial covenant ratios are in effect, the Company must maintain a minimum fixed charge coverage ratio of 1.10 to 1.00, and a maximum leverage ratio of 2.00 to 1.00. As of December 31, 2017, the Company was in compliance with all financial covenants. The Facility, as amended, provides for borrowings of up to $100.0 million through February 2021. Borrowings under the Facility for domestic base rate loans, including swing loans, bear interest at a daily base rate plus a margin ranging from 0.50% to 0.75%. Domestic London Interbank Borrowing Rate (“LIBOR”) loans bear interest equal to a LIBOR rate plus a margin ranging from 1.50% to 1.75%. As of December 31, 2017, the total commitments available from the lenders under the Facility were $100.0 million. At December 31, 2017, the Company had no outstanding borrowings and $0.6 million in outstanding letters of credit under the Facility, which reduce the amounts available for borrowing under the terms of the Facility. As of December 31, 2017 and 2016, the Company had $99.4 million and $78.7 million, respectively, of available borrowing capacity under the Facility. In February 2018, the Company entered into an amendment to the Credit Agreement which enables the Company repurchase up to $100 million of its common stock each year, subject to certain restrictions, and increased the limit on cumulative stock repurchases from $350 million to $600 million. Asia Revolving Credit Facilities The Company’s revolving credit facility agreement with HSBC Bank (China) Company Limited, Shanghai Branch (“HSBC”), or the “HSBC Facility,” provides the Company uncommitted dual currency revolving loan facilities of up to 40.0 million Chinese Renminbi (“RMB”), or $6.1 million, with a combined facility limit of RMB 60.0 million, or $9.2 million. As of December 31, 2017 and 2016, borrowings under the HSBC Facility remained suspended at the discretion of HSBC. The HSBC Facility matures in February 2021. For U.S. Dollar loans under the HSBC facility, the interest rate is 2.10% per annum plus LIBOR for three months or any other period as may be determined by HSBC at the end of each three month interest period. For RMB loans under the HSBC Facility, interest equals the one year benchmark lending rate effective on the loan draw-down date set forth by the People’s Bank of China plus 10%, payable on the maturity date of the related loan. The HSBC Facility may be canceled or suspended at any time at the discretion of the lender and contains provisions requiring the Company to maintain compliance with certain restrictive covenants. In January 2018, the Company entered into a revolving credit facility with China Merchants Bank Company Limited, Shanghai Branch (the “CMBC Facility”), which provides the Company a revolving loan facility of up to 30.0 million RMB, or $4.6 million, subject to consent by the lender. The CMBC Facility will mature in January 2019. For RMB loans under the CMBC Facility, interest is based on a benchmark interest rate plus a certain number of basis points upon agreement by the lender and the Company at the time of borrowing. The CMBC Facility may be canceled or suspended at any time by either party. Notes Payable Notes payable incur interest at fixed rates ranging from 1.95% to 2.83% and mature in 2018. The weighted average interest rate on outstanding borrowings as of December 31, 2017 and 2016 was 2.30% and 2.41%, respectively.
