Debt Disclosure [Abstract]  
On September 30, 2014, the Company entered into an agreement for a secured revolving credit facility (as amended by the Amendment discussed below, the "Credit Facility") to refinance our outstanding revolving loans. The Credit Facility provides an aggregate principal amount of up to $200.0 million, with sublimits of $10.0 million for the issuance of letters of credit and for $20.0 million of swingline loans. The Credit Facility also allowed us, subject to certain conditions, to request additional term loans or revolving commitments up to an aggregate principal amount of $150.0 million, plus an amount that would not cause our consolidated net leverage ratio, which is a ratio of the Company’s consolidated funded indebtedness to its consolidated EBIDTA, as defined in the agreement, to exceed 3.25 to 1.00. Revolving loans under the Credit Facility may be voluntarily prepaid and re-borrowed. At our option, the revolving loans accrue interest at a per annum rate equal to either LIBOR, plus a margin ranging from 1.25% to 2.00%, or the Base Rate, plus a margin ranging from 0.25% to 1.00% ("Applicable Margin"). The base LIBOR rate is, at our discretion, equal to either one, two, three, or six month LIBOR. The Base Rate is defined as the greater of Wells Fargo's prime rate, the Federal Funds Rate plus 0.50%, or one month LIBOR plus 1.00%. In each case, the Applicable Margin is determined based upon our consolidated net leverage ratio. Accumulated interest is due and payable quarterly, in arrears, for loans bearing interest at the Base Rate and at the end of the applicable interest period in the case of loans bearing interest at the adjusted LIBOR. The Credit Facility is secured by substantially all of our assets, and certain of our existing and future material domestic subsidiaries are required to guarantee our obligations under the Credit Facility. We are also required to comply with customary affirmative and negative covenants, as well as a consolidated net leverage ratio and an interest coverage ratio. All outstanding principal and accrued and unpaid interest is due upon the Credit Facility's maturity on September 30, 2019.
In February 2016, the Company entered into an amendment (the "Amendment") to the Credit Facility. The Amendment provides for an incremental term loan in the amount of $125.0 million ("Term Loan") that is coterminous with the existing Credit Facility. Principal payments on the Term Loan are due in quarterly installments beginning in June 2016. Amounts paid under the Term Loan may not be re-borrowed. The Term Loan is subject to mandatory repayment requirements in the event of certain asset sales or if certain insurance or condemnation events occur, subject to customary reinvestment provisions. The Company may prepay the Term Loan in whole or in part at any time, without premium or penalty, with prepayment amounts to be applied to remaining scheduled principal amortization payments as specified by the Company. The Term Loan is subject to the same interest rate terms and payment dates as the revolving loans. Under the terms of the Amendment, an additional tier was added such that the Applicable Margin now ranges from 1.25% to 2.00% for LIBOR loans, and 0.25% to 1.00% for Base Rate loans. The Amendment also permits the Company to elect to increase the maximum permitted consolidated net leverage ratio on a one-time basis to 4.00 to 1.00 following the issuance of convertible notes or high yield notes in an initial principal amount of at least $150.0 million. The Company incurred debt issuance costs in the amount of $0.7 million in conjunction with the execution of the Amendment.
We had $125.0 million outstanding under our Term Loan at March 31, 2016. At December 31, 2015, we had $40.0 million in revolving loans outstanding under the Credit Facility. There were no outstanding revolving loans at March 31, 2016. As of March 31, 2016, $200.0 million was available under our Credit Facility, of which $10.0 million was available for the issuance of letters of credit and $20.0 million for swingline loans. We had unamortized debt issuance costs of $1.6 million and $1.0 million at March 31, 2016 and December 31, 2015, respectively. At March 31, 2016, the Term Loan was carried net of unamortized debt issuance costs of $0.7 million in the accompanying Condensed Consolidated Balance Sheets. As of March 31, 2016, we were in compliance with the covenants under our Credit Facility.
Future maturities of principal under the Term Loan will be as follows for the years ending December 31:
