The Senior Notes are senior unsecured obligations, and are guaranteed on a senior unsecured basis by the Company’s subsidiaries that guarantee the Credit Facility and rank junior to, among other indebtedness, the Credit Facility to the extent of the value of the collateral securing the Credit Facility.

Credit Facility

On February 25, 2016, the Company amended its senior secured credit facility (the "Credit Facility" and such amendment, the "Amended Facility") to reduce commitment fees and provide borrowing capacity for general corporate purposes. The Amended Facility provides for a revolving credit line of up to $200.0 million, including up to $25.0 million available for letters of credit and up to $10.0 million in swingline loans. Availability under the Amended Facility is subject to a borrowing base calculated by reference to eligible accounts receivable in the United States, United Kingdom and Canada, eligible inventory in the United States, and cash on hand.

The Amended Facility reduced the borrowing capacity from $600.0 million to $200.0 million, as such the Company has written off $2.6 million of the deferred financing costs related to the credit facility.

The Credit Facility matures in November 2018. As of March 31, 2016, we had no borrowings outstanding under the Credit Facility, and $10.5 million of outstanding letters of credit. Subsequent to March 31, 2016, upon the completion of the bank's borrowing base audit, the Company had the capacity to borrow an additional $189.5 million subject to certain limitations in the Credit Facility. Weighted average interest rates under the Credit Facility for the twelve months ended December 31, 2015 were approximately 2.00%.

There have been no changes to the financial covenants disclosed in Item 8 of the Annual Report and the Company was in compliance with all financial covenants at March 31, 2016.
