At 2013年9月30日, the carrying value of the outstanding debt represented by the Notes was $297.100万年, including the remaining unamortized discount of approximately $3.300万年 related to the October Notes and the remaining unamortized premium of approximately $0.400万年 与十二月票据有关. Based on the quoted market price, the fair value of the Notes was determined to be approximately $315.400万年 at 2013年9月30日.
The fair value of the derivative instruments is computed based on the difference between the prices provided by the fixed-price contracts and forward market prices as of the specified date, as adjusted for basis differentials.
