CEO Alan Baratz, CHRO Sophie Ames, and Chief Legal Officer Diane Nguyen each had shares held back by the firm on May 13. The reason was simple: taxes due upon vesting of their RSUs. In each case, the filing says the shares were "withheld by the Issuer to satisfy tax withholding requirements in connection with the vesting of restricted stock units."

Baratz had 18,542 shares held back at $22.35 per share. After the move, he still held 3.30 million shares, which include 1.27 million unvested RSUs.
