(1)
Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issues with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value.
(2)
Includes amounts which represent the unamortized discount and premium. At June 30, 2013 and December 31, 2012, includes the valuation of certain fair value hedges associated with Dominion’s fixed rate debt of approximately $69 million and $93 million, respectively.
(3)
Includes amounts which represent the unamortized discount or premium.
(4)
Includes deferred issuance expenses of $2 million at June 30, 2013 and December 31, 2012.
