(2) This amount represents the aggregate of (a) the pre-tax income from continuing operations of MCN Investment and its majority-owned subsidiaries, (b) MCN Investment's share of pre-tax income of its 50% owned companies, and (c) any income actually received from less than 50% owned companies. (3) Fixed charges added to earnings are adjusted to exclude interest capitalized during the period and, therefore, may differ from fixed charges as defined. (4) In April 1996, MCN announced its intention to sell The Genix Group, its computer services subsidiary. For purposes of calculating the Ratio of Earnings to Fixed Charges, it has been classified as a discontinued operation and therefore excluded from the ratio for all periods presented. (5) Earnings for the year ended December 31, 1991 were not adequate to cover fixed charges. The amount of the coverage deficiency was $1,736,000.
