On February 14, 2017 (the "Closing Date"), the Borrowers amended the Term Loan Facility (the "Second Amended Term Loan Facility"). The Second Amended Term Loan Facility provides for a $213.3 million senior secured term loan B facility, which matures on February 14, 2024. The Second Amended Term Loan Facility, bears interest at the Borrowers' option of either (i) LIBOR plus a margin of 3.50% (decreased from a margin of 4.00% under the Term Loan Facility) or (ii) or an Alternate Base Rate ("ABR") plus a margin of 2.50% (decreased from a margin of 3.00% under the Term Loan Facility). There is no LIBOR floor (a decrease from a LIBOR floor of 1.00% under the Term Loan Facility). The Second Amended Term Loan Facility, among other terms, provides for an uncommitted incremental loan option (the "Incremental Facility") allowing for increases for borrowings under the Second Amended Term Loan Facility and borrowing of new tranches of term loans, up to an aggregate principal amount equal to (i) $65.0 million plus (ii) an additional amount (the "Incremental Facility Increase") provided, that after giving effect to such Incremental Facility Increase (as well as any other additional term loans), on a pro forma basis, the First Lien Net Leverage Ratio (as defined in the Second Amended Term Loan Facility) for the most recent four consecutive fiscal quarters does not exceed 4.00:1.00 and the Total Net Leverage Ratio (as defined in the Second Amended Term Loan Facility) for the most recent four consecutive fiscal quarters does not exceed 6.00:1.00. The First Lien Net Leverage Ratio and the Total Net Leverage Ratio each cap the cash netted against debt up to a maximum amount of $60.0 million (increased from $45.0 million under the Term Loan Facility). Additionally, the Second Amended Term Loan Facility also provides for an uncommitted incremental revolving loan option (the "Incremental Revolving Facility") allowing for an aggregate principal amount of up to $30.0 million, which will be secured on a pari passu basis by the collateral securing the Second Amended Term Loan Facility.

The Second Amended Term Loan Facility requires the Borrowers to make amortization payments (in quarterly installments) equal to 1.00% per annum with respect to the Second Amended Term Loan Facility with any remaining amount due at final maturity. The Second Amended Term Loan Facility principal payments commenced on March 31, 2017, with a final installment due on February 14, 2024. Voluntary prepayments are permitted, in whole or in part, subject to certain minimum prepayment requirements.

In addition, pursuant to the terms of the Second Amended Term Loan Facility, within 90 days after the end of each fiscal year, the Borrowers are required to make a prepayment of the loan principal in an amount equal to a percentage of the excess cash flow of the most recently completed fiscal year. Excess cash flow is generally defined as net income plus depreciation and amortization expense, less mandatory prepayments of the term loan, income taxes and capital expenditures, and adjusted for the change in working capital. The percentage of the excess cash flow used to determine the amount of the prepayment of the loan declines from 50% to 25%, and again to 0% at lower leverage ratios. Pursuant to the terms of the Second Amended Term Loan Facility, our net leverage ratio was 2.95x at December 31, 2017, resulting in an excess cash flow percentage of 25% and therefore, an excess cash flow payment of $2.1 million will be required to be paid in 2018.

In accordance with Accounting Standards Codification ("ASC") 470—Debt, the refinancing arrangement was deemed a modification of the Term Loan Facility and as such, an additional $1.1 million of original issue discount ("OID") incurred in connection with the Second Amended Term Loan Facility was added to the existing OID. As of December 31, 2017, the OID balance was $2.0 million, net of accumulated amortization of $1.5 million and was recorded as a reduction to the principal amount of the Second Amended Term Loan Facility outstanding as presented on the consolidated balance sheet and will be amortized as a component of interest expense over the term of the Second Amended Term Loan Facility. Financing costs of $1.4 million incurred in connection with the Second Amended Term Loan Facility were expensed in the period in accordance with ASC 470—Debt and are included in Other expenses in the consolidated statement of operations at December 31, 2017. In accordance with ASU 2015-15 Interest—Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements, deferred financing fees of $1.5 million, net of accumulated amortization of $1.8 million, are presented as a reduction to the Second Amended Term Loan Facility outstanding at December 31, 2017 as presented on the consolidated balance sheet, and will be amortized as a component of interest expense over the term of the Second Amended Term Loan Facility.

The carrying value of the long-term debt approximates fair value at December 31, 201 7 and 2016, and was derived from quoted market prices by independent dealers (Level 2 in the fair value hierarchy under ASC 820, Fair Value Measurements and Disclosures).
