The filing documents a proposed sale of 8,829 common shares with an aggregate market value of $645,841.35, to be executed via Morgan Stanley Smith Barney on NASDAQ. These shares were acquired as restricted stock units on 04/30/2021 and no other sales by the person are reported in the past three months.
