     calculated by adjusting net earnings for taxes on earnings; interest
     expense; capitalized interest cost, net of amortization; minority interest;
     and the portion of rentals representative of the interest factor, (ii) the
     Company considers one-third of rental expense to be the amount representing
     return on capital, and (iii) fixed charges comprise total interest expense,
     including capitalized interest and such portion of rentals.
