(a) The net effect on net electric operating revenues from realization of prior-period mark-to-market included in line 39 is zero. Realization of prior-period mark-to-market relates to cash flow recognition, not revenue recognition. The arithmetic opposites of amounts included in line 35 are included in lines 31 and 34. For example, line 35 shows that a prior-period mark-to-market gain of $2 million was transferred to “realized” for the total year of 2000. Lines 31 and 34 include amounts totaling $2 million of realized revenues for the total year of 2000.

	(a)		The net effect on pretax gross margin from realization of prior-period mark-to-market included in line 60 and in line 64 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 56 are included in line 52. The opposites of amounts included in line 57 are included in line 54. For example, line 56 shows that a prior-period mark-to-market gain of $2 million was transferred to “realized” for the total year of 2000. A $2 million realized gain is included in the $69 million on line 52 for the total year of 2000.
	(b)		Quarterly amounts do not total to the annual amounts because of intra-year mark-to-market eliminations.
