[1]	There was a negligible amount of ineffectiveness related to these hedges in 2015 and 2014.
[2]	Amounts include Otay Mesa VIE. All of SDG&E’s interest rate derivative activity relates to Otay Mesa VIE.
[3]	There was no hedge ineffectiveness on these swaps in the three months ended March 31, 2015 and $2 million in the three months ended March 31, 2014. All other changes in the fair values of the interest rate swap agreements are exactly offset by changes in the fair value of the underlying long-term debt and recorded in Other Income, Net.
