- ----------
(a)   The net effect on pretax gross margin from realization of prior-period
      mark-to-market included in line 43 and in line 44 is zero. Realization of
      prior-period mark-to-market relates to cash flow recognition, not earnings
      recognition. The opposites of amounts included in line 43 are included in
      line 44. For example, line 44 shows that a prior-period mark-to-market
      gain of $6 million was transferred to "realized" for the total year 2004.
      A $6 million realized gain is included in the $63 million on line 43 for
      the total year 2004.

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