Debt Disclosure [Abstract]
Long-Term Debt	NOTE 4 – LONG-TERM DEBT On May 17, 2017, the Company entered into a Fifth Amended and Restated Business Loan and Security Agreement with a syndication of 11 commercial banks (the “Credit Facility”). The Credit Facility: (i) included modifications to the Company’s Fourth Amended and Restated Business Loan and Security Agreement, (ii) matures on May 17, 2022, (iii) increased the borrowing ceiling up to $600.0 million without a borrowing base requirement, taking into account financial, performance-based limitations, and (iv) provided for an “accordion,” which permits additional revolving credit commitments of up to $300.0 million, subject to lenders’ approval. The Company has the option to borrow funds under the Credit Facility at interest rates based on both LIBOR (1, 3, or 6-month rates) and the Base Rate (as defined herein), at its discretion, plus their applicable margins. Base Rates are fluctuating per annum rates of interest equal to the highest of (i) the Federal Funds Open Rate, plus 0.5%, (ii) the Prime Rate (as defined under the Credit Facility) and (iii) the daily LIBOR rate, plus a LIBOR Margin between 1.00% and 2.00% based on its Leverage Ratio (as defined under the Credit Facility). The interest accrued based on LIBOR rates is to be paid on the last business day of the interest period (1, 3, or 6 months), while interest accrued based on the Base Rate is to be paid in quarterly installments. The Credit Facility also provides for letters of credit aggregating up to $60.0 million, which reduce the funds available under the Credit Facility when issued. The unused portion of the Credit Facility is subject to a commitment fee between 0.13% and 0.25% per annum based on the Leverage Ratio. The Credit Facility is collateralized by substantially all of the assets of the Company and requires that the Company remain in compliance with certain financial and non-financial covenants. The financial covenants require, among other things, that the Company maintain at all times an Interest Coverage Ratio (as defined under the Credit Facility) of not less than 3.00 to 1.00 and a Leverage Ratio of not more than 3.75 to 1.00 (subject to adjustment, in certain circumstances) for each fiscal quarter. As of September 30, 2019, the Company was in compliance with its covenants under the Credit Facility. As of September 30, 2019, the Company had $245.0 million long-term debt outstanding, ten outstanding letters of credit totaling $3.2 million, $2.0 million of net derivative obligations and unused borrowing capacity of $349.8 million under the Credit Facility (excluding the accordion). Taking into account the financial, performance-based limitations, available borrowing capacity (excluding the accordion) was $294.8 million as of September 30, 2019. The weighted-average interest rate on the Credit Facility (excluding any fees and unamortized debt issuance costs) was 3.6% and 3.4% for the three months ended September 30, 2019 and 2018, respectively, and 3.7% and 3.2% for the nine months ended September 30, 2019 and 2018, respectively.
