A 13F is a quarterly snapshot filed up to 45 days after quarter end; 13D/13G are filed above 5%; a Form 4 within two business days of a trade. Insider holdings are the shares each person holds directly — trusts, family and other indirect holdings are reported on lines of their own and are not added in. Codes are the SEC's: P open-market purchase, S open-market sale; M exercise, F tax withholding, A grant and G gift are routine. A 10b5-1 flag means the trade ran under a plan adopted in advance.
