Context

• A Rule 10b5-1 plan indicates the sale was pre-scheduled under an approved trading arrangement and does not, by itself, imply a change in the insider’s view of the company. Inclusion of unvested RSUs/PSUs in the reported holdings means the insider’s reported ownership may include shares not yet vested.
