(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 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 $5 million was transferred to “realized” for the total year 2004. A $5 million realized gain is included in the $64 million on line 48 for the total year 2004.

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