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 June 30,				Six months ended June 30,
	2014		2013		2014		2013
Basic shares outstanding		99,881		99,089		99,720		98,983
Effect of potential common stock:
Common stock awards		792		882		826		884
Senior subordinated convertible notes		150		191		150		204
Diluted shares outstanding		100,823		100,162		100,696		100,071

For the three and six month periods ended June 30, 2014 there were 749,666 and 770,665 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 579,350 and 587,350 outstanding stock options, respectively, that would have been antidilutive for the three and six month periods ended June 30, 2013.
