Share equivalents attributable to outstanding stock options, restricted stock units ("RSUs") and employee share purchase rights (ESPP) totaling 1.9 million and 0.8 million for the three months ended September 30, 2019 and 2018, respectively, and 2.0 million and 1.2 million for the six months ended September 30, 2019 and 2018, respectively, were excluded from the calculation of diluted net income per share because the combined exercise price and average unamortized grant date fair value upon exercise of these options and ESPP or vesting of RSUs were greater than the average market price of the Company's shares during the periods presented herein, and therefore their inclusion would have been anti-dilutive. Performance-based awards were not included because all necessary conditions have not been satisfied by the end of the respective period, and those shares were not issuable if the end of the reporting period was the end of the contingency period.
