[1] | Average interest rates on medium-term notes were 0.0% at December 31, 2014 and 2013
[2] | Includes long-term debt due within one year.
[3] | Interest rate on floating notes during 2014 and at December 31, 2013 was 0.7%.
[4] | At December 31, 2014 and 2013, the company had outstanding interest rate swap agreements with gross notional amounts of $1,000. Over the remaining terms of the notes, the company will receive fixed payments equivalent to the underlying debt and pay floating payments based on USD LIBOR (London Interbank Offered Rate). The fair value of outstanding swaps was an asset of $1 and $29 at December 31, 2014 and 2013, respectively.
[5] | During 2008, the interest rate swap agreement associated with these notes was terminated. The gain will be amortized over the remaining life of the bond, resulting in an effective yield of 3.85%.
