The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period. These outstanding stock awards are not included in the computation of diluted earnings per share because the effect would be anti-dilutive.  For both the quarter and six months ended June 30, 2015, the number of stock awards excluded from the computation was approximately 0.4 million. There were no anti-dilutive stock awards excluded from the computation for the quarter and six months ended June 30, 2014.
