Under this standard, basic earnings per share is computed by dividing net income applicable to common stockholders by the average number of common shares outstanding during the year. The computation of diluted earnings per share assumes that the average number of common shares outstanding is increased by dilutive common share equivalents and the conversion of securities having a dilutive effect, and that net income applicable to common stock is increased by dividends and after-tax interest on such securities. (2) Potentially dilutive securities at December 31, 1997 included shares issuable pursuant to certain stock-based compensation. These securities included 450,000 shares issuable upon the vesting of the restricted share units issued in 1996 as well as 270,000 shares issuable upon the exercise of stock options calculated using the treasury stock method. Potentially dilutive securities in 1997 were not included in the computation of diluted earnings per share because the effect would have been antidilutive.
