Debt and Capital Lease Obligations [Abstract]

Debt is summarized in the following table (in thousands):



	March 31, 2015		December 31, 2014
Senior notes	$	150,000	$	150,000
Credit facility	223,000		206,000
Long-term debt and capital lease obligations, net	$	373,000	$	356,000

We have two series of senior notes outstanding with an aggregate principal amount of $150 million ("Senior Notes") issued in a private placement transaction. Series A consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.01% and are due in full on September 30, 2021. Series B consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.11% and are due in full on September 30, 2023. Interest on each series of the Senior Notes is payable semi-annually on March 30 and September 30.

On March 13, 2015, we entered into an agreement to amend our revolving credit facility (the "Credit Facility") to increase the aggregate borrowing capacity from $350 million to $400 million and to keep the uncommitted availability of an additional $50 million to bring the total borrowings available to $450 million if certain prescribed conditions are met by the Company. The Credit Facility bears interest at variable rates from LIBOR plus 1.25% to a maximum of LIBOR plus 2.00%. Any outstanding balance under the Credit Facility is due August 29, 2019, when the Credit Facility matures. Our available capacity at any point in time is reduced by borrowings outstanding at the time and outstanding letters of credit which totaled $27.5 million at March 31, 2015, resulting in an available borrowing capacity under the Credit Facility of $149.5 million. In addition to those items under the Credit Facility, we had $12.6 million of outstanding letters of credit and performance guarantees and bonds from other sources as of March 31, 2015.

The terms of the Credit Facility and the Senior Notes require us to meet certain covenants, including, but not limited to, certain minimum cash flow ratios. We believe that we are in compliance with all such covenants contained in our credit agreements. Certain of our material, wholly-owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes.

In 2014, we entered into two interest rate swap agreements for a total notional amount of $50 million. See Note 11 - Derivative Instruments and Hedging Activities.

The estimated fair value of total debt at March 31, 2015 and December 31, 2014 approximated the book value of total debt. The fair value was estimated using Level 2 inputs by calculating the sum of the discounted future interest and principal payments through the date of maturity.
