(1) Unless otherwise indicated, the fair value of our Level 2 derivative instruments reflects our best estimate and is based upon exchange or over-the-counter quotations whenever they are available.  Quoted valuations may not be available due to location differences or terms that extend beyond the period for which quotations are available.  Where quotes are not available, we utilize other valuation techniques or models to estimate market values.  These modeling techniques require us to make estimations of future prices, price correlation and market volatility and liquidity.  Our actual results may differ from our estimates, and these differences could be positive or negative. 

(2) See Note 7 for additional information regarding our long-term debt.  The fair value of our long-term debt at September 30, 2012 is as follows:

(a) Amount excludes the related unamortized debt discount of $1.2 million.

(c)The estimated fair value of all debt, other than the MARAD debt, was determined using Level 1 inputs using the market approach.  The fair value of the MARAD debt was determined using a third party evaluation of the remaining average life and outstanding principal balance of the MARAD indebtedness as compared to other governmental obligations in the marketplace with similar terms.  The fair value of the MARAD Debt was estimated using Level 2 fair value inputs using the market approach.
