Context
This was a vesting/conversion of performance share units rather than an open-market sale or purchase. The withholding of 7,045 shares to cover taxes is a common, routine step and should not be read as a discretionary market sale. The vesting at 200% reflects achievement of the stated performance metric (relative TSR vs. S&P 600 Industrials).
