[1] Fuel Derivatives gain for the three months ended March 31, 2014 represents the changes in the fair value and settlements of certain Fuel Derivatives that were previously not elected to be accounted for under the normal purchase normal sale exception from derivative accounting. During the three months ended March 31, 2015, all settlements of Fuel Derivatives were recorded as operating and maintenance expense, as the normal purchase normal sale exception was elected for all Fuel Derivatives outstanding.
[2] There were no settlements during the reporting period.
