Diluted earnings per share is computed by dividing net income by the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows:

  Ended March 31
(In Thousands) 2013 2012
Weighted average shares outstanding used    
to compute basic earnings (loss) per share 32,076 32,010
Incremental dilutive shares attributable to stock    
options and restricted stock 404 383
Shares used to compute diluted earnings (loss)

     Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. During the three months ended March 31, 2013, 60,067 (none at March 31, 2012) of average out-of-the-money options to purchase shares were excluded from the calculation of incremental shares attributable to stock options and restricted stock.
