Dunaway William J 4

What Happened

The same day he sold 64,017 of those shares in an open-market transaction at an average price of $110.46 per share, generating proceeds of about $7,071,209.

Roughly speaking, the gross proceeds from the sale minus the exercise cost are about $5.95 million before taxes, fees, or other withholdings.
