Context
These transactions reflect routine equity compensation vesting (performance-based PSUs) rather than an open-market buy or discretionary sale. The withholding of shares to satisfy taxes is common in such vesting events and does not necessarily signal a change in the insider’s view of the company. Transaction codes: A = award/grant; F = shares withheld for tax liabilities.
