Open-market trades are Form 4 transaction codes P (purchase) and S (sale). Planned sales are those the filing marks as made under a Rule 10b5-1 plan. A P-code buy at the offering price within a day of the company's FWP, 424B prospectus or offering 8-K is marked Bought in the offering and left out of open-market buy counts and cluster buys. Prices and values are as stated in each Form 4. Stock prices aren't shown on this page. Not investment advice.
