Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed based on the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed based on the weighted-average number of shares of common stock outstanding plus the effect of potentially dilutive common shares outstanding during the period using the treasury stock method, which includes stock options, restricted stock awards and restricted stock units. The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended December 31,				Nine Months Ended December 31,

Numerator

Denominator
Denominator for basic earnings per share — weighted average shares outstanding	50,686		50,307		50,465		50,256
Dilutive effect of unvested restricted common stock (including restricted stock units) and options issued to employees and directors	837		377		820		411
Denominator for diluted earnings per share	51,523		50,684		51,285		50,667
Earnings per Common Share:
Basic net earnings per share	$	0.24	$	0.19	$	0.91	$	0.74
Diluted net earnings per share	$	0.24	$	0.19	$	0.90	$	0.73

For each of the three and nine months ended December 31, 2012, there were less than 0.1 million shares attributable to outstanding stock-based awards that were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For the three and nine months ended December 31, 2011, there were 0.7 million and 0.5 million shares, respectively, attributable to outstanding stock-based awards that were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.
