Transaction code F indicates a payment of exercise price or tax liability by delivering securities. In this case, 6,544 Illumina shares were disposed of to cover tax obligations, distinguishing it from a voluntary open-market purchase or sale of stock.

Does the ILMN Form 4 show buying or selling activity by the CEO?
