The Corporation’s $100,000,000 secured accounts receivable credit facility (the “AR Credit Facility”) expired by its own terms on April 20, 2013.

On April 19, 2013, the Corporation, through a wholly-owned consolidated special purpose subsidiary, established a $150,000,000 trade receivable securitization facility with SunTrust Bank and certain other lenders that may become a party to the facility from time to time (the “Trade Receivable Facility”). The Trade Receivable Facility is backed by trade receivables originated by the Corporation, which the Corporation then sells to the wholly-owned consolidated special purpose subsidiary - the balance of which was $314,998,000 at September 30, 2013. Borrowings under the Trade Receivable Facility bear interest at a rate equal to one-month LIBOR plus 0.6% and are limited to the lesser of the facility limit or of “eligible” receivables, as defined. The Corporation continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned consolidated special purpose subsidiary. The Corporation has the option to request an increase in the commitment amount by up to an additional $100,000,000, in increments of no less than $25,000,000, subject to receipt of lender commitments for the increased amount. The Trade Receivable Facility matures on April 19, 2014. At September 30, 2013, outstanding borrowings under the Trade Receivable Facility were classified as long-term on the consolidated balance sheet as the Corporation has the intent and ability to refinance amounts outstanding. The Trade Receivable Facility contains a cross-default provision to the Corporation’s other debt agreements.

The Corporation’s Credit Agreement, consisting of a $250,000,000 senior unsecured term loan (the “Term Loan Facility”) and a $350,000,000 senior unsecured revolving facility (the “Revolving Facility”), requires the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the “Ratio”) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 210 days so long as the Corporation maintains specified ratings on its long-term unsecured debt and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under the Revolving Facility, consolidated debt, including debt for which the Corporation is a co-borrower, may be reduced by the Corporation’s unrestricted cash and cash equivalents in excess of $50,000,000, such reduction not to exceed $200,000,000, for purposes of the covenant calculation. The Corporation was in compliance with this Ratio at September 30, 2013.

Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Corporation under the Revolving Facility. At September 30, 2013, the Corporation had $2,507,000 of outstanding letters of credit issued under the Revolving Facility.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three and nine months ended September 30, 2013, the Corporation recognized $279,000 and $823,000, respectively, as additional interest expense. For the three and nine months ended September 30, 2012, the Corporation recognized $260,000 and $768,000, respectively, as additional interest expense. The ongoing amortization of the terminated value of the forward starting interest rate swap agreements will increase annual interest expense by approximately $1,000,000 until the maturity of the 6.6% Senior Notes in 2018.
