     For the purpose of computing these ratios, earnings consist of the income from continuing ordinary activities before taxation of Group companies and income received from companies owned 50% or less, plus fixed charges (excluding capitalized interest). Fixed charges consist of interest (including capitalized interest) on all indebtedness, amortization of debt discount and expense and that portion of rental expense representative of the interest factor.
