Debt Disclosure [Abstract]
Debt and Financing Arrangements	Debt and Financing Arrangements Credit Facility The credit facility includes a revolving credit facility and a term loan facility. There were outstanding borrowings under the revolving credit facility of $37.7 million and $50.3 million as of September 30, 2020 and December 31, 2019, respectively. The weighted average interest rate applicable to these outstanding borrowings was 2.25% and 3.54% as of September 30, 2020 and December 31, 2019, respectively. The credit agreement contains customary affirmative and restrictive covenants, including, among others, financial covenants based on the Company's leverage and interest coverage ratios. See further discussion below regarding the Company's credit agreement and subsequent amendments to its leverage and interest coverage ratios. The credit agreement also includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations to be immediately due and payable. As of September 30, 2020, the Company was in compliance with all covenants under the credit agreement. As of September 30, 2020, the Company had available borrowings under its revolving credit facility of $358.7 million after giving effect to $3.6 million of outstanding letters of credit. On July 3, 2020, the Company amended its credit agreement dated December 23, 2019 (the “First Amendment”). The First Amendment amended the credit agreement to, among other things, modify the maximum net average total leverage ratio for each of the fiscal quarters ending after June 30, 2020 and on or before September 30, 2021 (for such period of time, the “Covenant Relief Period”). During the Covenant Relief Period, in lieu of complying with a maximum net average total leverage ratio of 3.50 to 1.00, the Company is required to comply with maximum net average total leverage ratios of 5.50 to 1.00 for the current fiscal quarter ending September 30, 2020, 6.50 to 1.00 for the fiscal quarters ending December 31, 2020 and March 31, 2021, 4.50 to 1.00 for the fiscal quarter ending June 30, 2021 and 4.00 to 1.00 for the fiscal quarter ending September 30, 2021. Beginning with the fiscal quarter ending December 31, 2021, the Company will be required to comply with its previous maximum net average total leverage ratio of 3.50 to 1.00. The First Amendment also modified the interest rate applicable to borrowings under the credit agreement during the Covenant Relief Period from a range of 1.00% to 1.75% over the Eurodollar Rate (as defined in the credit agreement, which includes a 0.75% floor during the Covenant Relief Period) or 0.00% to 0.75% over the Base Rate (as defined in the credit agreement) to a range of 1.00% to 2.50% over the Eurodollar Rate or 0.00% to 1.50% over the Base Rate. The First Amendment modified the commitment fee rate payable during the Covenant Relief Period in respect of unused portions of the revolving credit facility from a range of 0.15% to 0.30% to a range of 0.15% to 0.45%. During the Covenant Relief Period, the Company has the right under the amended credit agreement to establish a new revolving credit facility (a “364-Day Revolving Credit Facility”) providing for up to $150.0 million of revolving commitments of a new class maturing no later than the earlier of (x) 364 days from establishment of such facility and (y) the latest maturity applicable to then-outstanding term loans and existing revolving credit loans under the credit facility. The lenders under the credit facility will not be under any obligation to provide commitments under a 364-Day Revolving Credit Facility, and the establishment of a 364-Day Revolving Credit Facility is subject to customary conditions precedent. The First Amendment amended the incremental facilities provision in the credit agreement by permitting the Company to request additional term loans and/or increases to the existing revolving credit facility in an aggregate principal amount not to exceed (i) $225.0 million (the “Free and Clear Incremental Amount”) plus (ii) an unlimited amount so long as the net average secured leverage ratio (as defined in the credit agreement) does not exceed 2.25 to 1.00 on a pro forma basis (the “Incremental Provision”). Under the amended credit agreement, the Incremental Provision is unavailable during the Covenant Relief Period. In addition, at any time that a 364-Day Revolving Credit Facility is in effect, outstanding commitments and loans under such 364-Day Revolving Credit Facility will reduce the Free and Clear Incremental Amount. In connection with amending its credit agreement, the Company incurred fees and expenses of approximately $1.1 million, of which approximately $0.8 million was capitalized as debt issuance costs included in other assets and long-term debt on the consolidated balance sheet. The remaining $0.3 million was included in interest expense, net for the three and nine months ending September 30, 2020. See Note 1 for further discussion on the Company's evaluation and response to the COVID-19 pandemic.

There were outstanding borrowings under the Company's local credit facilities of $2.7 million and $3.8 million as of September 30, 2020 and December 31, 2019, respectively. The weighted average interest rate applicable to the outstanding borrowings was 1.75% and 2.29% as of September 30, 2020 and December 31, 2019, respectively. As of September 30, 2020, the Company had available borrowings remaining under these local credit facilities of $60.2 million.
