Insights

Corporate Governance Expert

TL;DR: A Form 3 discloses an officer role with no beneficial ownership; this is routine for governance records.

The filing documents Mr. Jeffrey Masom's relationship to the issuer as an officer and Director-Subadviser and explicitly states no securities are beneficially owned. For governance oversight, the form formally establishes reporting obligations rather than indicating share ownership or transactions. There are no disclosures of holdings, derivatives, or changes that would affect control or voting rights.

Securities Analyst

TL;DR: Initial Section 16 filing reports no beneficial ownership; this provides no market-moving ownership data.

The Form 3 confirms the reporting person and event date of 04/29/2025 and records that the report was executed by power of attorney on 08/28/2025. Because the filing states explicitly that there are no securities beneficially owned, there are no holdings, acquisitions, dispositions, or derivative positions disclosed that would affect investor assessment of insider ownership.
