TL;DR: Routine Form 4 filed showing a transaction code S with numeric entries but no contextual materiality data.

The document is a Form 4 for Calamos Convertible & High Income Fund reporting a transaction dated 08/11/2025. The filing lists Common Stock, transaction code S, and numeric values including 2,000 and $10.901, with ownership shown as Direct.

Corporate Governance Expert

TL;DR: A single-officer Form 4 disclosure was signed and filed; content is procedural and lacks broader governance implications.

The form shows the reporting person filed individually and signed the report on 08/11/2025. Relationship to the issuer is recorded as Officer with the title FormerChief Compliance Officer. The form presents specific transaction fields (including 2,000 and $10.901) but omits explanatory narrative in the explanation section. Based solely on the filing text, this appears to be a standard insider reporting disclosure without further governance detail provided.
