(3) Fixed charges added to earnings are adjusted to exclude interest capitalized during the period and, therefore, may differ from fixed charges as defined.

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.
