Context
Tax-withholding dispositions (code F) are common when RSUs or performance awards vest — the company keeps a portion of the vested shares to cover tax withholding. These transactions are administrative and do not necessarily indicate the insider is selling shares for liquidity or signaling a view on the stock; they differ from open-market sales.
