Summary of Accounting Policies [Abstract]

Schedule of Weighted Average Diluted Shares Outstanding Table

Earnings per Share - Basic earnings per share were calculated using net earnings and the weighted-average number of shares of common stock outstanding during the respective year. Diluted earnings per share were calculated using net earnings and the weighted-average number of shares of common stock and potential common stock outstanding during the respective year. Potentially dilutive common stock consisted of stock options and the premium over the conversion price on Roper's senior subordinated convertible notes based upon the trading price of the Company's common stock. The effects of potential common stock were determined using the treasury stock method (in thousands):
