Senior Revolving Line of Credit

At December 31, 2012, we were authorized to borrow up to $500 million under a senior revolving line of credit, which is supported by a credit agreement with a group of banks.  This senior credit facility, which has a five-year term expiring in August 2016, allows us to request an increase in the total commitment by up to $250 million and to request a one-year extension of the maturity date.  The applicable interest rate under this agreement is based on either the Prime Rate, the Federal Funds Rate or LIBOR, depending upon the specific type of borrowing, plus an applicable margin based on our credit rating and other fees.  At December 31, 2012, we had $85.8 million outstanding at an average interest rate of 2.03% under this agreement.

Senior Term Loan

Our senior term loan consists of an unsecured $200 million variable-rate agreement, which matures in March 2014.  We are required to make an installment payment of $50 million in March 2013, with the remaining $150 million payable at maturity.  The applicable interest rate under this agreement is based on either the Prime Rate, the Federal Funds Rate or LIBOR, depending upon the specific type of borrowing, plus an applicable margin based on our credit rating and other fees.  At December 31, 2012, we had $200 million outstanding under this variable-rate senior term loan facility at an interest rate of 1.26%.

Senior Notes

At December 31, 2012, our senior notes consist of two separate issuances.  The first is $150 million of 6.08% senior notes, which mature in July 2014.  We are required to make an installment payment of $50 million in July 2013, with the remainder due upon maturity.  Interest payments are due semiannually in January and July of each year.  The second is $250 million of 3.375% senior notes, which mature September 2015, with interest payments due semiannually in March and September of each year.  We may redeem for cash some or all of the notes based on a redemption price set forth in the note indenture.

Our financing arrangements require us to maintain certain covenants and financial ratios.  We were in compliance with all covenants and financial ratios at December 31, 2012.
