Computation Of Net Income Per Share

Note 18 Computation of Net Income per Share

     The Company presents basic and diluted earnings per share ("EPS") amounts. Basic EPS is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the applicable period. Diluted EPS is calculated by dividing net income available to 3D Systems' common stockholders by the weighted average number of common and common equivalent shares outstanding during the applicable period. The following table is a reconciliation of the numerator and denominator of the basic and diluted income per share computations for the years ended December 31, 2011, 2010 and 2009:

(in thousands, except per share amounts)		2011		2010		2009
Numerator:
Net income available to 3D Systems common stockholders: numerator for
basic net income per share	$	35,420	$	19,566	$	1,066
Add: Effect of dilutive securities
Stock options, other equity compensation, convertible redeemable
preferred stock and debentures		—		—		—
Net income available to 3D Systems common stockholders: numerator for
dilutive net income per share	$	35,420	$	19,566	$	1,066
Denominator:
Denominator for basic net income per share: weighted average shares		49,748		46,168		45,088
Add: Effect of dilutive securities
Stock options, other equity compensation, convertible redeemable
preferred stock and debentures		975		760		122
Denominator for dilutive net income per share (1)		50,723		46,928		45,210
Income per share
Basic	$	0.71	$	0.42	$	0.02
Diluted	$	0.70	$	0.42	$	0.02

⁽¹⁾ The average outstanding diluted shares calculation excludes options covering 708 shares in 2009 with an exercise price that exceeds the average market price of shares during the period, since the effect of their inclusion would have been anti-dilutive resulting in a reduction to the net earnings per share. The average outstanding diluted shares calculation also excludes shares that may be issued upon conversion of the outstanding senior convertible notes because their conversion price exceeded the market price of the shares at December 31, 2011.
