Preferred and preference dividend requirements consist of an amount equal to the
pre-tax earnings that would be required to meet dividend requirements on
preferred stock and preference stock.

Earnings are deemed to consist of income from continuing operations (before
extraordinary loss) that includes earnings of BGE's consolidated
subsidiaries, income taxes (including deferred income taxes and investment tax
credit adjustments), and fixed charges other than capitalized interest.
