Context

These were grants (awards) rather than purchases or sales; the $0 acquisition price and the vesting schedules mean the awards vest over time and are contingent on continued service. The derivative award represents an option-like award that must vest (per F3) before it can be converted into shares. This Form 4 appears to have been filed on time.
