Certain exercisable stock options were excluded from the computations of diluted EPS because the exercise price of these options was greater than the average period market prices. There were no stock options excluded from the calculation of diluted EPS at March 31, 2017. The number of stock options outstanding, which were not included in the calculation of diluted EPS, was 0.2 million, with an exercise price of $26.02, at March 31, 2016.
