Ownership / ultimate parent (EU-owned?)

Ownership / ultimate parent (EU-owned?)

Why important?

Ownership and jurisdiction shape access obligations (e.g. CLOUD Act), governance and risk assumptions in audits.

How measured?

Scale 0–5 + N/A:
  • 0 = Ultimate parent clearly non-EU (no EU governance/separation)
  • 1 = Non-EU ultimate parent (EU entity only operational/contracting)
  • 2 = Non-EU parent, but stronger EU structures (e.g. EU subsidiary, limited governance)
  • 3 = EU operations/governance mechanisms in place, ultimate parent remains non-EU
  • 4 = EU-owned, but relevant non-EU influence/control issues (e.g. investors/structure)
  • 5 = Ultimate parent EU-owned (control in the EU)
  • N/A = no reliable evidence

Validation questions (RFP)

  • Who is the ultimate parent? Which corporate and jurisdictional chain applies to disclosure obligations?
