Explanation of responses
- F1Shares issued upon settlement of vested restricted stock units.
- F2Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock or a cash settlement.
- F3The restricted stock units ("RSUs") were granted with both (a) a liquidity event-based vesting condition and (b) a service-based vesting condition, both of which conditions must be satisfied in order for the RSUs to vest. The liquidity event-based condition was satisfied upon the closing of the Issuer's initial public offering (the "IPO"). The shares that vested on the closing date of the IPO, and the shares that vested thereafter through May 15, 2015, were settled on May 15, 2015. The service-based vesting condition provides that 25% of the total number of shares on March 14, 2015 and 1/48th of the total number of shares monthly thereafter, subject to the holder's continuous service through each such date.
- F4The earlier of (i) March 27, 2021 or (ii) the recipient's termination date.
