The ratio of earnings to fixed charges is determined by dividing earnings by fixed charges. Fixed charges consist of the total of (i) interest, whether expensed or capitalized; (ii) amortization of debt expense and discount or premium relating to any indebtedness, whether expensed or capitalized; (iii) such portion of rental expense as can be demonstrated to be representative of the interest factor in the particular case; and (iv) preferred stock dividend requirements of majority-owned subsidiaries and fifty-percent-owned persons, excluding in all cases items which would be or are eliminated in consolidation. Earnings consist of pretax income from continuing operations plus the amount of fixed charges, adjusted to exclude (i) the amount of any interest capitalized during the period and (ii) the actual amount of any preferred stock dividend requirements of majority-owned subsidiaries and fifty-percent-owned persons which were included in such fixed charges amount but not deducted in the determination of pretax income. The ratio of earnings to fixed charges is not meaningful for periods in which there were no material fixed charges.
