Financing Activities

Credit Facility

In October 2016, we entered into a credit agreement, which consists of a $350,000 aggregate principal amount term loan B facility and a $160,000 revolving line of credit facility. The net proceeds from this transaction have been used to repay in full our senior secured asset-based revolving credit and letter of credit facility ("ABL Facility") and will be used to redeem all of our remaining outstanding 7.75% Senior Subordinated Notes due 2019 ("2019 Notes") in November 2016 at a redemption price equal to 101.938% of the principal amount thereof plus accrued and unpaid interest thereon and for payment of transaction related expenses.

New York Bonds 2016

In the nine months ended September 30, 2016, we completed a financing transaction involving the issuance by the New York State Environmental Facilities Corporation of $15,000 aggregate principal amount of Solid Waste Disposal Revenue Bonds Series 2014R-2 (“New York Bonds 2016”). We borrowed the proceeds of the offering of the New York Bonds 2016 to finance or refinance certain capital projects in the state of New York, and to pay certain costs of issuance of the New York Bonds 2016.

Loss on Debt Extinguishment

We recorded a loss on debt extinguishment of $191 and $736 in the three and nine months ended September 30, 2016, respectively, as compared to $345 and $866 during the three and nine months ended September 30, 2015, respectively, associated with the following:
