Common stock equivalents are anti-dilutive in 1994 since there is a net loss that year, however, such amounts were not removed from the calculation as the amounts were not material. (2) In accordance with APB No. 15, if the exercise price is greater than the average market price or ending market price, convertible subordinated debentures are not considered in fully diluted earnings per common share. Although the exercise prices of the outstanding convertible subordinated debentures are less than the market prices during the relevant periods, the ratio of convertible subordinated debentures interest, net of taxes, to convertible subordinated debentures shares is anti-dilutive for all periods shown, and is therefore excluded from the fully diluted earnings per common share calculation.
