Fair enough, I did some more digging. $1.99 billion in stock-based compensation was recognized in the first 3 months of the year. $637 million of that was given to the CEO according to his October 2016 employment contract, which all vested at IPO in March 2017. Then there's the pre-IPO employee RSUs. Those typically are subject to 4 years of time vesting, as well as a performance requirement that triggered when the company IPOed. $1.3 billion of those were recognized as of March 31 2017 because they met their performance vesting requirement (IPO-ing). Those were probably the shares that had already satisfied the time-vesting requirement. The company still hasn't recognized an additional $1.3 billion in stock-based compensation that will be recognized on its financial statements over a weighted-average period of the next 3.1 years. Those were probably issued relatively recently since they haven't met their time vesting requirement yet.
