EXHIBIT (11.1)----STATEMENT RE: COMPUTATION OF DILUTED EARNINGS PER SHARE Diluted earnings per share computations assume the exercise of stock options to purchase shares of common stock. The shares assumed exercised are based on the weighted average number of shares under options outstanding during the period and only include those options for which the exercise price is less than the average share price during the period. The net additional shares issuable are calculated based on the treasury stock method and are added to the weighted average number of shares outstanding during the period.
