Owned after: shares held right after the person's latest buy or sale, from the Form 4 the date links to. % of shares: that holding over the shares outstanding on the latest cover page. Only people who bought or sold in this period are listed, and options, restricted units and shares held by others are not counted, so the rows are not a total of what insiders own.
