Debt Disclosure [Abstract]
Debt	Debt In February 2017, we entered into a secured five-year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Third Amended Credit Agreement), which increased the principal amount of our revolving credit facility to up to $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, and provided an additional $175.0 million accordion feature. Borrowings may be used to finance working capital needs, for letters of credit and for general corporate purposes in the ordinary course of business, including the financing of permitted acquisitions (as defined in the Third Amended Credit Agreement). All obligations under the Third Amended Credit Agreement were guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Third Amended Credit Agreement (the Guarantors). The obligations were also secured by a Third Amended and Restated Pledge and Security Agreement, dated as of February 17, 2017, entered into by us and the Guarantors which grante to the administrative agent, for the benefit of the lenders, a security interest, subject to certain exceptions, in substantially all of the non-real estate assets of the Guarantors. These assets included, but were not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries. All revolving loans were due on the maturity date, February 17, 2022. Borrowings under the Third Amended Credit Agreement could have been made as alternate base rate loans or euro-currency loans. Alternate base rate loans bore interest that included a base reference rate plus a spread of 37.5 to 75.0 basis points, depending on our leverage ratio. The base reference rate was the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Reserve Bank of New York (NYFRB) Rate in effect on such day plus ½ of 1.0% and (c) the adjusted LIBOR for a one month interest period in dollars on such day (or if such day was not a business day, the immediately preceding business day) plus 1.0%. Euro-currency loans bore interest based on adjusted LIBOR plus a spread of 137.5 to 175.0 basis points, depending on our leverage ratio. In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Third Amended Credit Agreement, we were required to pay a quarterly fee of 20 to 30 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Third Amended Credit Agreement. The Third Amended Credit Agreement contained customary representations, warranties, covenants, mandatory prepayments and events of default under which our payment obligations could have been accelerated. If an event of default occurred, the lenders could have, among other things, terminated their commitments and declared all outstanding borrowings to be immediately due and payable together with accrued interest and fees. The financial covenants included requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to an election to increase the maximum leverage ratio to 3.50 to 1.00 for three fiscal quarters in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00. The Third Amended Credit Agreement generally permitted us to pay cash dividends to our shareholders, provided that (i) no default or event of default had occurred and was continuing or would result from the dividend payment and (ii) our leverage ratio did not exceed 2.75 to 1.00. If our leverage ratio exceeded 2.75 to 1.00, we could nonetheless make up to $20.0 million in restricted payments, including cash dividends, during the fiscal year, provided that no default or event of default had occurred and was continuing or would result from the payments. On October 16, 2020, we entered into the Fourth Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A, as administrative agent, and the lenders party thereto (the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement amends and restates the Third Amended Credit Agreement, and provides for a revolving credit facility with up to a $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, in addition to a $175.0 million accordion feature. Borrowings may be used to finance working capital needs, for letters of credit and for general corporate purposes in the ordinary course of business, including the financing of permitted acquisitions (as defined in the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement extends the maturity, the date on which all amounts borrowed or outstanding under the Fourth Amended Credit Agreement are due, from February 17, 2022 to March 31, 2024. All obligations under the Fourth Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Fourth Amended Credit Agreement (the Guarantors). The obligations are also secured by a Fourth Amended and Restated Pledge and Security Agreement, dated as of October 16, 2020, entered into by us and the Guarantors which grants to the administrative agent, for the benefit of the lenders, a security interest, subject to certain exceptions, in substantially all of our and the Guarantors’ non-real estate assets. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries. Borrowings under the Fourth Amended Credit Agreement can be made as alternate base rate loans or euro-currency loans. Alternate base rate loans bear interest at a base reference rate plus a spread of 62.5 to 100.0 basis points, depending on our leverage ratio. The base reference rate is the greatest of (a) the prime rate in effect on such day, (b) the NYFRB rate in effect on such day plus ½ of 1%, and (c) the adjusted LIBOR for a one month interest period in dollars on such day (or if such day is not a business day, the immediately preceding business day) plus 1%. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 162.5 to 200.0 basis points, depending on our leverage ratio. Based on our leverage ratio as of December 31, 2020, the spread was 162.5 basis points. In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Fourth Amended Credit Agreement, we are required to pay a quarterly fee of 25 to 35 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Fourth Amended Credit Agreement. The Fourth Amended Credit Agreement contains customary representations and warranties, covenants, mandatory prepayments and events of default under which our payment obligations may be accelerated. If an event of default occurs, the lenders may, among other things, terminate their commitments and declare all outstanding borrowings to be immediately due and payable together with accrued interest and fees. The financial covenants include requirements to maintain (1) a total net leverage ratio of no more than 3.25 to 1.00, subject to a one-time election to increase the maximum total net leverage ratio to 3.50 to 1.00 for one fiscal year in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00. We are permitted to net up to $50.0 million of unrestricted domestic cash and cash equivalents against indebtedness in the calculation of the total net leverage ratio. The Fourth Amended Credit Agreement generally permits us to pay cash dividends to our shareholders, provided that (i) no default or event of default has occurred and is continuing or would result from the dividend payment and (ii) our total net leverage ratio does not exceed 2.75 to 1.00. If our total net leverage ratio exceeds 2.75 to 1.00, we may nonetheless make up to $20.0 million in restricted payments, including cash dividends, during the fiscal year, provided that no default or event of default has occurred and is continuing or would result from the payments. Our total net leverage ratio did not exceed 2.75 to 1.00 as of December 31, 2020. In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75.0 million of our $450.0 million revolving credit facility. This transaction was designated as a cash flow hedge and qualified for hedge accounting treatment. We terminated the interest rate swap on September 30, 2020. As a result, we settled the interest rate swap for $2.4 million on October 2, 2020, representing the fair value of the interest rate swap on the date of termination. Both Rogers and the counterparties released each other from all obligation under the interest rate swap agreement, including the obligation to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to the agreed upon notional principal amount of $75.0 million. We borrowed $150.0 million under our revolving credit facility as a precautionary measure in order to increase our cash position and preserve financial flexibility given current uncertainty in the global markets resulting from the COVID-19 pandemic, during the three months ended March 31, 2020. We did not borrow anything further under our revolving credit facility for the year ended December 31, 2020. We were not required to make any quarterly principal payments under the Third Amended Credit Agreement, nor are we required to make any quarterly principal payments under the Fourth Amended Credit Agreement, however, we made discretionary principal payments totaling $248.0 million, $105.5 million and $5.0 million on our revolving credit facility in 2020, 2019 and 2018, respectively. We had $25.0 million in outstanding borrowings under our revolving credit facility as of December 31, 2020. We incurred interest expense on our outstanding debt, net of the impacts of our interest rate swap, of $6.5 million, $7.2 million, and $6.1 million for the years ended December 31, 2020, 2019 and 2018, respectively. We incurred an unused commitment fee of $0.7 million for the year ended December 31, 2020, and $0.6 million for the years ended December 31, 2019 and 2018, respectively. We had $2.3 million and $1.2 million of outstanding line of credit issuance costs as of December 31, 2020 and 2019, respectively, which will be amortized over the life of the Fourth Amended Credit Agreement. We recorded amortization expense of $0.6 million, $0.6 million and $0.6 million for the years ended December 31, 2020, 2019 and 2018, respectively, related to these deferred costs.
