- It links repeat appearances of officers, directors, large holders, and signers across shells to SEC filing references.
Field notes
The guide maps takeover questions to specific disclosures: Form 8-K Item 5.01 for changes in control, Schedule 13D for holders above 5%, and Item 5.06 when a company exits shell status. It also defines deal terms such as “clean shell” while noting that “clean” is the seller's word, not a finding. The site says its cross-shell name listings quote filings and SEC numbers, and cautions that an appearance is not evidence of wrongdoing.
