Data availability
Unum Group’s corporate-linkage information is best described as partial: SEC exhibit-21 disclosures and UK Companies House filings confirm the existence and jurisdictions of Unum Group’s principal subsidiaries and its UK branch, but none of the sources reviewed discloses specific ownership or voting percentages for individual subsidiaries, so no percentage figures are stated. A wider set of subsidiary and affiliate names appears in Zavia’s underlying registry data than is repeated in the table above; only relationships that could be corroborated against SEC or Companies House filings are presented here as verified.
