How to read SEC Schedule 13G

A Schedule 13D and a Schedule 13G both disclose beneficial ownership of more than 5% of a US company's voting shares. A 13D is the long form, filed by holders who may seek to influence or control the company, and it must state what they intend to do. A 13G is the short form, open only to passive holders and to certain institutions holding in the ordinary course of business, and it asks no question about intent.
