Future Marketing and Trading Mark-to-Market Realization

As of September 30, 2007, Pinnacle West had accumulated net mark-to-market gains of $10 million related to our power marketing and trading activities. We estimate that these gains will be reclassified to realized gains as the underlying commodities are delivered, as follows: 2007, $3 million; 2008, $2 million; and thereafter, $5 million.


(a)		Net effect on pretax gross margin from realization of prior-period mark-to-market included in line 53 and in line 54 is zero. Realization of prior-period mark-to-market relates to cash flow recognition, not earnings recognition. The arithmetic opposites of amounts included in line 53 are included in line 54. For example, line 54 shows that a prior-period mark-to-market gain of $3 million was transferred to “realized” for the third quarter of 2007. A $3 million realized gain is included in the $6 million on line 53 for the third quarter of 2007.

(b)		Quarterly amounts do not total to annual amounts because of intra-year mark-to-market eliminations.
