Future Marketing and Trading Mark-to-Market Realization
As of December 31, 2005, Pinnacle West had accumulated net mark-to-market gains of $45 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: 2006, $14 million; 2007, $20 million; and 2008, $11 million.
| (a) | Net effect on pretax gross margin from realization of prior-period mark-to-market included in line 48 and in line 49 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 48 are included in line 49. For example, line 49 shows that a prior-period mark-to-market gain of $17 million was transferred to “realized” for the fourth quarter of 2005. A $17 million realized gain is included in the $22 million on line 48 for the fourth quarter of 2005. | |
| (b) | Quarterly amounts do not total to annual amounts because of intra-year mark-to-market eliminations. |
