Debt and Credit Agreement | Debt and Credit Agreements 2016 Senior Credit Facility On January 5, 2016, the Company entered into a $400.0 million senior secured credit facility pursuant to a credit agreement with certain lenders, Wells Fargo Securities, LLC as sole lead arranger, and Wells Fargo Bank, National Association as administrative agent (as subsequently amended as discussed below, the “Prior Credit Agreement”). The Prior Credit Agreement provided for (a) a five-year revolving credit facility of $200.0 million, which was subsequently increased pursuant to the amendment discussed below (the “Prior Revolving Credit Facility”) and (b) a five-year $200.0 million term loan facility (the “Prior Term Loan Facility” and together with the Prior Revolving Credit Facility, the “Prior Facilities”). In addition, the Prior Credit Agreement included a letter of credit sub-limit of up to $10.0 million and a swing line loan sub-limit of up to $10.0 million. The Prior Credit Agreement had an expiration date of January 5, 2021, upon which date all remaining outstanding borrowings were due and payable. Loans under the Prior Facilities bore interest, at the Company’s option, at a rate equal to either (a) the LIBOR Rate, plus an applicable margin ranging from 1.50% to 2.25% per annum based on the Company’s consolidated total net leverage ratio (as defined in the Prior Credit Agreement), or (b) an alternate base rate equal to the highest of (i) the prime rate, (ii) the federal funds rate plus 0.50%, and (iii) LIBOR for an interest period of one month, plus an applicable margin ranging from 0.50% to 1.25% per annum based on the Company’s consolidated total net leverage ratio (as defined in the Prior Credit Agreement). Undrawn commitments under the Prior Revolving Credit Facility were subject to a commitment fee ranging from 0.20% to 0.35% per annum based on the Company’s consolidated total net leverage ratio on the average daily unused portion of the Prior Revolving Credit Facility. On each of April 11, 2017 and December 26, 2017, the parties entered into amendments to the Prior Credit Agreement. Under these amendments, the Prior Revolving Credit Facility was increased from $200.0 million to $315.0 million and certain other modifications were made. In connection with the December 2017 amendment, the Company incurred and capitalized an additional $2.1 million of debt issuance costs. 2019 Revolving Credit Facility On November 15, 2019, the Company refinanced the Prior Credit Agreement and entered into an Amended and Restated Credit Agreement (the “A&R Credit Agreement”) with the lenders from time to time party thereto, Wells Fargo Securities, LLC, Citizens Bank, N.A., and JPMorgan Chase Bank, N.A., as joint lead arrangers and Wells Fargo Bank, National Association, as administrative agent. The A&R Credit Agreement replaced the Prior Credit Agreement and provides for (a) a five-year revolving credit facility of $500.0 million (the “Current Revolving Credit Facility”) and (b) an uncommitted incremental loan facility of up to $250.0 million (the “Incremental Facility”). In addition, the A&R Credit Agreement includes a letter of credit sub-limit of up to $15.0 million and a swing line loan sub-limit of up to $25.0 million. The A&R Credit Agreement has an expiration date of November 15, 2024, upon which date all remaining outstanding borrowings will be due and payable. On November 15, 2019, the $80.0 million outstanding term loan balance under the Prior Facilities was transferred to the Current Revolving Credit Facility. Loans under the Current Revolving Credit Facility bear interest, at the Company’s option, at a rate equal to either (a) the LIBOR Rate, plus an applicable margin ranging from 1.25% to 2.00% per annum based on the Company’s Consolidated Total Net Leverage Ratio (as defined in the A&R Credit Agreement), or (b) an alternate base rate equal to the highest of (i) the prime rate, (ii) the federal funds rate plus 0.50%, and (iii) LIBOR for an interest period of one month plus 1.00%, plus an applicable margin ranging from 0.25% to 1.00% per annum based on the Company’s Consolidated Total Net Leverage Ratio. Undrawn commitments under the Current Revolving Credit Facility are subject to a commitment fee ranging from 0.15% to 0.30% per annum based on the Company’s Consolidated Total Net Leverage Ratio on the average daily unused portion of the Current Revolving Credit Facility. The applicable margin for and certain other terms of any term loans under the Incremental Facility will be determined prior to the incurrence of such loans. The Company is permitted to make voluntary prepayments at any time without payment of a premium or penalty. The A&R Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company and its subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, dividends, and other distributions. The A&R Credit Agreement contains financial covenants that require the Company and its subsidiaries to not exceed a maximum consolidated total net leverage ratio and maintain a minimum interest coverage ratio. In addition, the A&R Credit Agreement contains certain customary events of default including, but not limited to, failure to pay interest, principal and fees or other amounts when due, material misrepresentations or misstatements in any representation or warranty, covenant defaults, certain cross defaults to other material indebtedness, certain judgment defaults and events of bankruptcy. The Company’s obligations under the A&R Credit Agreement and any swap obligations and banking services obligations owing to a lender (or an affiliate of a lender) are guaranteed by certain of its domestic subsidiaries and secured by substantially all of its and such subsidiary guarantors’ assets. In connection with entering into the A&R Credit Agreement, and as a condition precedent to borrowing loans thereunder, the Company and certain of the Company’s other direct and indirect subsidiaries have entered into certain ancillary agreements, including, but not limited to, a reaffirmation agreement, which amends certain terms of the existing collateral agreement and reaffirms their obligations under the existing guaranty agreement. The Company was in full compliance with all covenants as of December 31, 2019. The refinancing of the Prior Credit Agreement was evaluated in accordance with ASC 470-50, Debt - Modifications and Extinguishments. In determining whether the refinancing was to be accounted for as a debt extinguishment or a debt modification, the Company considered whether lenders within the syndicate remained the same or changed and whether the changes in debt terms were substantial. This assessment was performed on an individual lender basis within the syndicate. As a result, the refinancing was accounted for as a modification with the exception of certain lenders that exited the syndicate. The exit of certain lenders resulted in an immaterial write-off of existing unamortized debt issuance costs. The remaining unamortized debt issuance costs related to debt modification, along with the new deferred costs, will be amortized over the remaining term of the A&R Credit Agreement. In connection with the A&R Credit Agreement, the Company incurred and capitalized an additional $2.3 million of debt issuance costs. The debt issuance costs are being amortized to interest expense using the straight-line method through 2024. Amortization expense related to debt issuance costs was approximately $2.2 million, $2.3 million, and $1.6 million for the years ended December 31, 2019, 2018, and 2017, respectively. Interest expense (exclusive of fees and debt issuance cost amortization) was approximately $3.6 million, $7.5 million, and $6.3 million for the years ended December 31, 2019, 2018, and 2017, respectively.

_________________________________________________ (1) Presented as a direct deduction from the carrying amount of the debt liability in the Consolidated Balance Sheets. (2) Presented in other long-term assets in the Consolidated Balance Sheets. As of December 31, 2019, the carrying value of debt of $50.0 million approximates its fair value. The fair value of the outstanding balance of the Current Revolving Credit Facility was calculated using a discounted cash flow model based on current market interest rates available to the Company.
