Context
This was an option exercise followed by same-day open-market sales of the shares acquired on May 14 (a common pattern when executives exercise options and sell some or all of the resulting shares). McLean paid $148,596 to exercise 18,300 shares and realized about $706k from the 10,200 shares sold on May 14; net proceeds attributable to the May 14 exercise-and-sale (sales minus exercise cost for the 10,200 exercised that day) are roughly $623k. The May 15 exercised shares (8,100) were acquired and not sold according to this filing.
