Schedule 13D is the full form for owners of more than 5% of a class of a company's voting shares, required when the owner does not qualify for the shorter Schedule 13G. It asks the filer to state the purpose of the transaction. Schedule 13G is the shorter form for owners of more than 5% of a class of a company's voting shares. The percentage is the one the lead filer gave on the cover page; filings that name several reporting persons list the highest one.
