The weighted-average interest rate for installment loans outstanding at July 1, 2014 and December 31, 2013 was 10.46% and 10.54%, respectively. The debt is secured by certain land and building assets and is subject to certain prepayment penalties.

On November 1, 2013, we entered into Omnibus Amendment No. 1 and Consent to Credit Agreement and Guaranty with respect to our revolving credit facility dated as of August 12, 2011 with a syndicate of commercial lenders led by JP Morgan Chase Bank, N.A., PNC Bank, N.A., and Wells Fargo, N.A. The amended revolving credit facility, which has a maturity date of November 1, 2018, remains an unsecured, revolving credit agreement under which we may borrow up to $200.0 million. The amendment provides us with the option to increase the revolving credit facility by $200.0 million, up to $400.0 million, subject to certain limitations.

The terms of the amended revolving credit facility require us to pay interest on outstanding borrowings at the London Interbank Offered Rate (“LIBOR”) plus a margin of 0.875% to 1.875%, depending on our leverage ratio, or the Alternate Base Rate, which is the higher of the issuing bank’s prime lending rate, the Federal Funds rate plus 0.50% or the Adjusted Eurodollar Rate for a one month interest period on such day plus 1.0%. We are also required to pay a commitment fee of 0.125% to 0.30% per year on any unused portion of the amended revolving credit facility, depending on our leverage ratio. The weighted-average interest rate for the revolving credit facility at both July 1, 2014 and December 31, 2013 was 3.96%, including the impact of interest rate swaps. At July 1, 2014, we had $50.0 million outstanding under the revolving credit facility and $144.6 million of availability, net of $5.4 million of outstanding letters of credit.

The lenders’ obligation to extend credit under the amended revolving credit facility depends on us maintaining certain financial covenants, including a minimum consolidated fixed charge coverage ratio of 2.00 to 1.00 and a maximum consolidated leverage ratio of 3.00 to 1.00. The amended revolving credit facility permits us to incur additional secured or unsecured indebtedness outside the facility, except for the incurrence of secured indebtedness that in the aggregate exceeds 15% of our consolidated tangible net worth or circumstances where the incurrence of secured or unsecured indebtedness would prevent us from complying with our financial covenants. We were in compliance with all covenants as of July 1, 2014.
