Debt

On March 22, 2011, the Company entered into an agreement with investors to issue $75 million in fixed-rate, senior notes at interest rates varying from 3.77% to 4.47%. These notes will have a six-year average life with a final maturity in November 2018. Proceeds from the sale of the notes will be received in November 2011 and used to repay maturing debt and for general corporate purposes.

On April 7, 2011, the Company modified its revolving credit facility. The capacity of the credit facility has been increased from $300 million to $350 million. 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. Currently, when fully drawn, the interest rate is at LIBOR plus 1.75%. During the second quarter, the credit facility was used to repay the Company's $42.7 million balance on a term loan that would have matured in June 2012 and will be used for future liquidity needs.

The Company is in compliance with all of its debt covenants as of September 30, 2011.
