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 because the effect would be anti-dilutive. For the quarters ended March 31, 2018 and 2017, the number of stock awards excluded from the computation was approximately 4.3 million and 12.2 million, respectively.
