[1] Mortgage notes payable pertain to mortgage loans on our headquarters office complex. These mortgage loans are secured by land, buildings, and improvements with a net book value of $60.1 million at June 30, 2011. These mortgages bear interest at 5.7% with repayment terms of monthly interest and principal debt service and a January 2023 maturity.

[2] In April 2011, we sold in a registered underwritten public offering, $250 million in aggregate principal amount of 4.25% senior notes due April 2016. Interest on these senior notes is payable semi-annually. We may redeem some or all of these senior notes at any time prior to their maturity at a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed, or (ii) the sum of the present value of the remaining scheduled payments of principal and interest thereon, discounted to the redemption date at a discount rate equal to a designated U.S. Treasury rate, plus 30 basis points, plus accrued and unpaid interest thereon to the redemption date.

[3] In August 2009, we sold in a registered underwritten public offering, $300 million in aggregate principal amount of 8.60% senior notes due August 2019. Interest on these senior notes is payable semi-annually. We may redeem some or all of these senior notes at any time prior to their maturity, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon, discounted to the redemption date at a discount rate equal to a designated U.S. Treasury rate, plus 50 basis points, plus accrued and unpaid interest thereon to the redemption date.

[4] Effective in April 2011, we acquired a controlling interest in RJES (see Note 1 for further discussion of this transaction). This financing balance pertains to pre-existing term loan financing of RJES. The term loan bears interest at a variable rate indexed to the Euro Interbank Offered Rate and is secured by certain assets of RJES. The repayment terms include annual principal repayments and a September 2013 maturity.
