Purchase value is the sum of shares × reported price, in US dollars. Unpriced transactions count toward purchases and distinct buyers but add no dollar value; * marks an incomplete total. Each reporting insider is counted once per company, by CIK when available. Joint filings are counted by their primary reporting owner.
