NOTES:

(a) Earnings and fixed charges as defined in instructions for Item 503 of
Regulation S-K.

(b) Excludes a cumulative effect of change-in-accounting after-tax loss of $11
million; if included, ratio would be 1.81.

(c) Excludes a cumulative effect of change-in-accounting after-tax gain of $18
million; if included, ratio would be unchanged, since the change-in-accounting
resulted from the equity-based subsidiary MCV Partnership. The total net incomes
of equity-based subsidiaries are excluded from determining earnings as defined.

(d) We determined that we do not hold the controlling interest in our trust
preferred security structures. Accordingly, those securities have been
deconsolidated as of December 31, 2003. Therefore, our trust preferred
securities that were previously included in mezzanine equity, have been
eliminated due to deconsolidation and are reflected in Long-term debt - related
parties.

(e) The MCV Partnership and the FMLP are variable interest entities and
Consumers was determined to be the primary beneficiary. Therefore, these
entities are no longer equity method subsidiaries and we have consolidated the
MCV Partnership and the FMLP into our consolidated financial statements for the
first time as of and for the quarter ended March 31, 2004.
