NOTE: For the purpose of calculating this ratio, (i) earnings from continuing operations have been calculated by adjusting earnings from continuing operations for taxes on earnings from continuing operations; interest expense; amortization of capitalized interest, net of capitalized interest; noncontrolling interest; and the portion of rentals representative of the interest factor, (ii) Abbott 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.
