Earnings Per Share [Abstract]

Earnings Per Share

(17)Earnings per Share

Basic earnings per share is computed by dividing income attributable to CAI common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock; however, potential common equivalent shares are excluded if their effect is anti-dilutive.

The following table sets forth the reconciliation of basic and diluted net income per share for the years ended December 31, 2013, 2012 and 2011 (in thousands, except per share data):

	Year Ended December 31,
	2013		2012		2011
Numerator
Net income attributable to CAI common stockholders used in the calculation
of basic and diluted earnings per share	$	63,926	$	63,465	$	50,189
Denominator
Weighted-average shares used in the calculation of basic earnings per share		22,157		19,495		19,295
Effect of dilutive securities:
Stock options and restricted stock		515		450		398
Weighted-average shares used in the calculation of diluted earnings per share		22,672		19,945		19,693
Net income per share attributable to CAI common stockholders:
Basic	$	2.89	$	3.26	$	2.60
Diluted	$	2.82	$	3.18	$	2.55

The denominator used in the calculation of diluted income per share for the years ended December 31, 2013, 2012 and 2011 excluded options for 271,300 shares, 363,000 shares and 232,500 shares, respectively, of common stock granted to employees and directors because their effect would have been antidilutive.
