In March 2011, the Company entered into an agreement to issue $75 million in fixed-rate, senior notes. These notes were issued in November 2011 at fixed coupon rates of 3.77%, 4.14% and 4.47% per annum with maturities in 2016, 2017 and 2018, respectively. Proceeds from the sale of these notes have been used to repay maturing debt and for general corporate purposes.

In April 2011, the Company modified its revolving loan facility. The capacity of the credit facility was increased from $300 million to $350 million and the facility will mature in April 2016. Interest rates on borrowings under the credit facility are at LIBOR plus a margin based on the Company's leverage ratio. The credit facility was used to repay the Company's floating rate term loan that would have matured in June 2012 and will be used for future liquidity needs.

The borrowings under the long-term revolving loan agreement had an average interest rate of 1.67% and 1.45% for the years ended December 31, 2012 and 2011, respectively.

The aggregate amounts of contractual maturities on long-term debt each year for the five years subsequent to December 31, 2012, are as follows: 2013, $62.6 million; 2014, $12.0 million; 2015, $11.7 million; 2016, $131.7 million; and 2017, $91.0 million.

The Company has approximately $62.6 million of long-term debt that matures in 2013. It is the Company's intention to refinance these maturities under the long-term revolving loan agreement and accordingly, that maturing debt has been classified as long-term debt in the Consolidated Balance Sheet.

The Company has $247.0 million available under the revolving credit facility and $25.5 million available under other lines of credit from several banks at December 31, 2012.

Substantially all of the senior loan agreements contain restrictions concerning interest coverage, borrowings, investments and tangible net worth amounts.
