Where a filer also filed an amendment, the original report is used. A 13F report covers holdings the filer has investment discretion over, which can include client accounts, funds it manages and positions held to hedge or trade; filers that list other managers in a combination report may overlap with those managers’ own reports, so totals are not de-duplicated. Only managers with $100 million or more in 13(f) securities file.3 Observed facts, not a forecast.
