(1) December 31, 2010 includes a $500 million term loan entered into in 2007, and a $16.6 million construction loan entered into in 2008 which are effectively fixed by the use of interest rate swaps but evaluated for estimated fair value at the floating rate. The $500 million term loan was repaid in June 2011 from the net proceeds received from our $500 million debt offerings also completed in June 2011 and with cash on hand. The $16.6 million construction loan interest rate swap matured and was not extended in conjunction with the one-year extension of the loan in July 2011.
