     Certain stock awards outstanding were not included in the computation of diluted earnings per share above because they would not have had a dilutive effect. The excluded stock awards represented an aggregate of 0.5 million shares at March 31, 2017. There were no anti-dilutive stock awards outstanding at March 31, 2016.
