In January 2012, we repaid in full the outstanding principal balance of the $298.0 million 2007 Term Loan due May 31, 2012. We used a portion of the net proceeds from the public offering of 41,745,000 shares of common stock in December 2011 to repay the 2007 Term Loan.  The aggregate repayment amount was $298.2 million, including the outstanding principal amount and accrued interest through January 5, 2012.
