4About this data
Each row is one manager's position as disclosed in one Form 13F-HR filing; managers below the Form 13F reporting threshold do not appear. Values, quantities and manager names are as reported in each filing. A row totals the entries of one filing that share a security class and option type; a value or quantity is shown as not comparable when those entries differ in currency or unit. A restatement replaces the original filing and every earlier amendment for the same period; an amendment adding new holdings is listed alongside the filing it supplements and labelled as such. Positions are matched to this listing through the security identifiers reported in the filing.
