West Region

Fourth Quarter: Commodity Margin in our West segment decreased by $17 million in the fourth quarter of 2012 compared to the prior year period. Primary drivers were:
              lower contribution from hedges and
lower revenue due to the expiration of contracts, partially offset by
+ an increase in Commodity Margin on our open position driven by higher market spark spreads on higher generation volumes.

Full Year: Commodity Margin in our West segment decreased by $67 million in 2012 compared to 2011. Primary drivers were:
              lower contribution from hedges
lower market power prices associated with our Geysers assets and
lower revenue due to the expiration of contracts, partially offset by
+ an increase in Commodity Margin on our open position driven by higher market spark spreads and
+ increased generation driven primarily by improved market conditions, less hydroelectric generation and a nuclear power outage in California during 2012.

Texas Region

Fourth Quarter: Commodity Margin in our Texas segment decreased by $14 million in the fourth quarter of 2012 compared to the prior year period. Primary drivers were:
              lower contribution from hedges and
weak market pricing conditions due to mild weather.

Full Year: Commodity Margin in our Texas segment increased by $101 million in 2012 compared to 2011. Primary drivers were:
            +   higher contribution from hedging activities that secured favorable pricing despite lower market prices driven by milder weather in the third quarter of 2012 compared to the prior year period
+ higher generation driven by lower natural gas prices in the first half of 2012 and
+ an extreme cold weather event in Texas in February 2011 that negatively impacted our Commodity Margin in the first quarter of the prior year, which did not recur in the current year.

North Region

Fourth Quarter: Commodity Margin in our North segment increased by $12 million in the fourth quarter of 2012 compared to the prior year period. Primary drivers were:
            +   higher regulatory capacity revenues and
+ to a far lesser extent, increased generation.

Full Year: Commodity Margin in our North segment increased by $25 million in 2012 compared to 2011. Primary drivers were:
            +   York Energy Center achieving commercial operation in March 2011
+ higher contribution from hedges and
+ increased generation driven by lower natural gas prices, partially offset by
lower regulatory capacity revenues and
lower nodal pricing in PJM during 2012.

Southeast Region

Fourth Quarter: Commodity Margin in our Southeast segment decreased by $19 million in the fourth quarter of 2012 compared to the prior year period. The primary drivers were:
             

expiration of a PPA during the third quarter of 2012, which has since been recontracted, and
lower contribution from hedges.

Full Year: Commodity Margin in our Southeast segment increased by $5 million in 2012 compared to 2011. Primary drivers were:
            +   higher contribution from hedges and
+ higher generation resulting from lower natural gas prices, largely offset by
the negative impact from the expiration of a PPA during the third quarter of 2012, which has since been recontracted.
