Earnings Per Share [Abstract]

Earnings per Share Data

Earnings per Share Data

Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of the nil coupon non-redeemable convertible unsecured loan notes, RSUs, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive. Out-of-money stock options are excluded from diluted earnings per share because they are anti-dilutive. For the nine- months ended September 30, 2014, basic earnings per share is equal to diluted earnings per share because all outstanding stock awards and convertible loan notes are considered anti-dilutive during periods of net loss. The following table sets forth the weighted-average shares used in calculating the earnings per share for the three and nine- month periods ended September 30, 2014 and 2013.

	Three Months Ended   September 30,		Nine Months Ended   September 30,
	2014	2013	2014	2013
Basic weighted-average shares	22,835,000	22,376,000	22,764,000	22,229,000
Conversion of unsecured loan notes	7,000	7,000	—	7,000
Unexercised options and unvested RSUs	374,000	151,000	—	222,000
Diluted weighted-average shares	23,216,000	22,534,000	22,764,000	22,458,000

Fuel Tech had 1,661,000 and 2,031,000 weighted average equity awards outstanding at September 30, 2014 and 2013, respectively, that were not dilutive for the purposes of inclusion in the calculation of diluted earnings per share but could potentially become dilutive in future periods.
