Derivatives</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">During August 2010, we entered into six 12-month forward-starting interest rate swap agreements for an aggregate notional amount of $250.0 million at a weighted average rate of 3.16%. We entered into these swap agreements in order to hedge the expected interest payments associated with fixed rate debt forecasted to be issued in 2011. The swap agreements each have an effective date of August 1, 2011 and a termination date of August 1, 2021. We expect to settle the swap agreements when the forecasted debt is issued. We assessed the effectiveness of these swap agreements as hedges at inception and on September 30, 2010 and consider these swap agreements to be highly effective cash flow hedges. The swap agreements are recorded as a liability under the caption “Accounts payable and accrued liabilities” on our consolidated balance sheets at their aggregate estimated fair value of $6.0 million at September 30, 2010. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">During August and September 2007, we entered into four six-month Treasury lock agreements totaling $250.0 million at a weighted average rate of 4.212%. We entered into these Treasury lock agreements in order to hedge the expected interest payments associated with a portion of our October 2007 issuance of $300.0 million of notes which mature in 2013. These Treasury lock agreements were settled in cash on October 17, 2007 for an amount equal to the present value of the difference between the locked Treasury rates and the unwind rate. We reassessed the effectiveness of these agreements at the settlement date and determined that they were highly effective cash flow hedges under ASC 815 for $250.0 million of the $300.0 million of notes as intended. The prevailing Treasury rate exceeded the rates in the Treasury lock agreements and, as a result, the counterparties to those agreements made payments to us of $1.6 million, which was recorded as other comprehensive income. The settlement amounts are being amortized over the life of the debt as a yield reduction. We expect to record $0.3 million of amortization during the next 12 months. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">In June 2006, we entered into two $125.0 million, two-month Treasury lock agreements in order to hedge the expected interest payments associated with a portion of our July 2006 issuance of $350.0 million of notes which mature in 2011. These Treasury lock agreements were settled in cash on July 11, 2006, concurrent with the pricing of the $350 million of notes, for an amount equal to the present value of the difference between the locked Treasury rates and the unwind rate. We reassessed the effectiveness of these agreements at the settlement date and determined that they were highly effective cash flow hedges under ASC 815 for $250.0 million of the $350.0 million of notes as intended. The prevailing Treasury rate exceeded the rates in the Treasury lock agreements and, as a result, the counterparty to those agreements made payments to us of $1.2 million, which was recorded as other comprehensive income. The settlement amounts are being amortized over the life of the debt as a yield reduction. We expect to record $0.2 million of amortization during the next 12 months. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">During January 2008, the unconsolidated joint venture we have with a state pension fund investor entered into an interest rate swap contract (see Notes 6 and 14). </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif;
