For the nine months ended September 30, 1997 they had an anti-dilutive effect, however, they were included in the primary and fully diluted earnings per share computation as they had a dilutive effect on net earnings. (b) For the nine months ended September 30, 1997, the assumed conversion of preferred stock had an anti-dilutive effect on earnings per share, resulting from the assumed reduction in Preferred Stock dividends, and therefore was excluded from the fully diluted earnings per share calculation.
