----------
(a)  The net effect on net electric operating revenues from realization of
     prior-period mark-to-market included in line 37 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 32 are
     included in lines 28 and 31. For example, line 32 shows that a prior-period
     mark-to-market gain of $0 million was transferred to "realized" for the
     total year 1999. Lines 28 and 31 include amounts totaling $0 million of
     realized revenues for the year 1999.
