Earnings Per Share [Abstract]

Earnings Per Share

3. 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 period. 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 period. 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 Roper's common stock. The effects of potential common stock were determined using the treasury stock method.  Weighted average shares outstanding are shown below (in thousands):

	Three months ended September 30,				Nine months ended September 30,
	2014		2013		2014		2013
Basic shares outstanding		100,068		99,207		99,837	$	99,058
Effect of potential common stock:
Common stock awards		788		905		815		894
Senior subordinated convertible notes		150		190		151		200
Diluted shares outstanding		101,006		100,302		100,803		100,152

For the three and nine month periods ended September 30, 2014 there were 670,000 and 781,000 outstanding stock options, respectively, that were not included in the determination of diluted earnings per share because doing so would have been antidilutive, as compared to 551,850 and 601,350 outstanding stock options, respectively, that would have been antidilutive for the three and nine month periods ended September 30, 2013.
