Dilutive effect of stock options and unvested restricted stock		6,568		13,588		7,058		13,896

Basic earnings per share	$	0.08	$	0.12	$	0.39	$	0.28
Dilutive earnings per share	$	0.08	$	0.11	$	0.37	$	0.25

Diluted earnings per share reflects the reduction in earnings per share assuming options or other contracts to issue common stock were exercised or converted into common stock under the treasury stock method. The dilutive effect of options to purchase shares of common stock and restricted shares were included in the diluted earnings per share in the three and nine months ended September 30, 2014 and 2013, respectively. 624,478 and 1,196,888 restricted shares were determined to be anti-dilutive and were not included in the calculation of diluted earnings per share for the three and nine months ended September 30, 2014, respectively. There were no anti-dilutive shares included in the calculation of diluted earnings per share for the three and nine months ended September 30, 2013.
