Insights

Corporate Governance Expert

Form 3 shows an officer with no beneficial ownership disclosed.

The filing identifies Jeffrey S. Phlegar as an officer of CHI and states explicitly that no securities are beneficially owned. This is a straightforward initial Section 16 disclosure rather than a transaction report.

For governance and alignment considerations, the absence of reported ownership is a factual disclosure only; the document does not state any compensation, grants, or pending transactions that would change ownership.
