Total unrecognized compensation expense related to share options under all plans as well as the number of options outstanding and exercisable were immaterial as of December 31, 2019.

During the nine-month period ended December 31, 2019, the Company granted 8.2 million unvested restricted share unit ("RSU") awards. Of this amount, approximately 6.4 million are plain-vanilla unvested RSU awards that vest over four years, with no performance or market conditions, and with an average grant date price of $9.22 per award. Further, approximately 1.8 million unvested shares represent the target amount of grants made to certain key employees whereby vesting is contingent on certain market conditions. The average grant date fair value of these awards contingent on certain market conditions was estimated to be $11.92 per award and was calculated using a Monte Carlo simulation. The number of shares contingent on market conditions that ultimately will vest will range from zero up to a maximum of 3.6 million based on a measurement of the percentile rank of the Company’s total shareholder return over a certain specified period against the Standard and Poor’s (“S&P”) 500 Composite Index, and will cliff vest after a period of three years, to the extent such market conditions have been met.

As of December 31, 2019, approximately 17.0 million unvested RSU awards under all plans were outstanding, of which vesting for a targeted amount of 3.5 million awards is contingent primarily on meeting certain market conditions. The number of shares that will ultimately be issued can range from zero to 7.0 million based on the achievement levels of the respective conditions. During the nine-month period ended December 31, 2019, no shares vested in connection with the awards with market conditions granted in fiscal year 2017.

As of December 31, 2019, total unrecognized compensation expense related to unvested RSU awards under all plans was approximately $139.5 million, and will be recognized over a weighted-average remaining vesting period of 2.4 years.
