The short answer
Schedules 13D and 13G are SEC filings made by anyone who acquires beneficial ownership of more than 5% of a class of a public company’s registered voting equity. Schedule 13D is the full disclosure, including the holder’s intentions; Schedule 13G is a shorter form for eligible passive and institutional holders.
