Investigate Schedule 13 data #45

Open katie-lamb opened 4 months ago

katie-lamb commented 4 months ago

Overview

The Schedule 13 (specifically Schedule 13D?) is another SEC form that is filed when a person or group acquires more than 5% of a voting class of a company's equity shares. See here for more explanation and some examples. The owner company is responsible for filing the Schedule 13 and it must be filed within 10 days of the purchase. It seems like it's often published as tables (do they share a common layout). GEM mentioned that they use it "to find beneficial ownership data sources."

I'm not exactly sure what information this would provide in addition to that in the Ex. 21. But even if there's no additional information it could supplement or validate what we extract from the Ex. 21 if the table is in a standard format or easier to extract.

Success Criteria

An understanding of what the Schedule 13 contains, its common layouts, and whether it's worth attempting to extract it. How would we use it in our existing pipeline?

### Next steps
* [ ] Catalog the layouts of Schedule 13
* [ ] Catalog the data that is provided by Schedule 13
* [ ] Compare this to the data that is available through Ex. 21
* [ ] Make a plan for archiving and extracting Schedule 13 if it seems helpful.
