Note 6.  Indebtedness

Our principal debt obligations at September 30, 2012 were: our $750,000 unsecured revolving credit facility; four public issuances of unsecured senior notes, including: $250,000 principal amount due 2016 at an annual interest rate of 4.30%, $200,000 principal amount due 2020 at an annual interest rate of 6.75%, $300,000 principal amount due 2021 at an annual interest rate of 6.75% and $350,000 principal amount due 2042 at an annual interest rate of 5.625%; and $702,636 aggregate principal amount of mortgages secured by 56 of our properties with maturity dates from 2013 to 2043.  The 56 mortgaged properties had a carrying value of $975,116 at September 30, 2012.  We also have two properties subject to capital leases totaling $13,900 at September 30, 2012; these two properties had a carrying value of $15,667 at September 30, 2012.

In connection with the acquisitions discussed in Note 3 above, during the nine months ended September 30, 2012, we assumed $112,153 of mortgage debt, which was recorded at an aggregate fair value of $117,271.  These mortgages have a weighted average interest rate of 5.77% and a weighted average maturity of 4.6 years.  We recorded the assumed mortgages at their fair value, which exceeded their outstanding principal balances by $5,118.  We determined the fair value of the assumed mortgages using a market approach based upon Level 2 inputs (significant other observable inputs) in the fair value hierarchy.

In January 2012, we repaid all $225,000 of our 8.625% unsecured senior notes at their maturity date.  We funded this repayment using borrowings under our revolving credit facility.

In February 2012, we paid in full a mortgage loan encumbering one of our properties that had a principal balance of approximately $12,400, an interest rate of 6.03% and a maturity date in March 2012.  In April 2012, we paid in full 17 mortgage loans encumbering 17 of our properties that had an aggregate principal balance of $32,576, weighted average interest rate of 6.95% and maturity dates in June and July 2012.  In June 2012, we paid in full a mortgage loan encumbering one of our properties that had a principal balance of approximately $3,140, an interest rate of 6.07% and a maturity date in September 2012.  In October 2012, we paid in full a mortgage loan encumbering one of our properties that had a principal balance of approximately $4,159, an interest rate of 6.50% and a maturity date in January 2013.

In July 2012, we sold $350,000 of unsecured senior notes.  The notes require interest at a fixed rate of 5.625% per annum and are due in 2042.  Net proceeds from this sale of the notes, after underwriting discounts, fees and other expenses were approximately $338,566.  Interest on the notes is payable quarterly in arrears.  We used a part of the net proceeds of this offering to repay borrowings outstanding under our revolving credit facility and we used the remaining net proceeds from this offering to prepay a part of our Federal National Mortgage Association, or FNMA, secured term loan and for general business purposes, which included funding a part of our recent acquisitions of properties discussed in Note 3 above.

In August 2012, we prepaid approximately $199,197 of the outstanding principal balance of our FNMA secured term loan that had an interest rate of 6.4% at August 31, 2012 and a maturity date in September 2019, using, among other funds, net proceeds from our July 2012 debt offering.  As a result of this prepayment, 11 of the 28 properties securing this loan were released from the related mortgage.  Also, as a result of this prepayment, we recorded a loss on early extinguishment of debt of approximately $6,349 consisting of a debt prepayment premium, legal fees and the write off of unamortized deferred financing fees.

We have a $750,000 unsecured revolving credit facility that is available for acquisitions, working capital and general business purposes.  Our revolving credit facility has a maturity date in June 2015 and, subject to meeting certain conditions and our payment of a fee, we may extend the maturity date for one year to June 2016.  In addition, our revolving credit facility includes a feature under which maximum borrowings may be increased to up to $1,500,000 in certain circumstances.  Borrowings under our revolving credit facility bear interest at LIBOR plus a spread of 160 basis points.  We also pay a facility fee of 35 basis points per annum on the maximum amount of borrowings available under our revolving credit facility.  Both the interest rate spread and the facility fee are subject to adjustment based upon changes to our credit ratings.  The weighted average annual interest rate for borrowings under our revolving credit facility was 1.8% for the three and nine months ended September 30, 2012, respectively.  As of September 30, 2012, we had $55,000 outstanding and $695,000 available under our revolving credit facility.
