In November 2011, we amended our unsecured senior revolving credit facility to increase the facility from $250.0 million to $300.0 million and extend the term of the facility until November 2016. The senior revolving credit facility provides for borrowings up to $300.0 million and is subject to certain commitment fees. Loans made under the senior revolving credit facility bear interest at a variable rate. Loan proceeds may be used for general corporate purposes, including working capital, permitted acquisitions, capital expenditures and repayment of existing indebtedness. The credit agreement also provides for an uncommitted incremental facility that permits us, subject to certain conditions, to request an increase in the senior credit facility of up to $50.0 million. At December 31, 2011, $130.0 million of the $300.0 million senior revolving credit facility was unused.

In October 2010, we issued $100.0 million in 4.00% Series A Senior Notes. The Series A Senior Notes will mature on October 13, 2021 and are payable in five annual installments of $20.0 million, commencing October 13, 2017. Interest is payable quarterly. The Series A Senior Notes are unsecured.

Approximate maturities of these obligations over the next five years are $8.0 million in 2012, $6.7 million in 2013, $6.7 million in 2014, $6.7 million in 2015, $176.7 million in 2016, and $137.2 million thereafter. Some debt agreements require us to maintain certain financial ratios and minimum net worth and contain restrictions on the total amount of debt. We were in compliance with our debt covenants at December 31, 2011.
