FAQ

What does the Calamos CPZ Form 3/A filing report for John S. Koudounis?

The Form 3/A reports John S. Koudounis’s insider status with the trust. It lists him as a Vice President and notes he will serve as a trustee effective 9-1-25, without reporting any security transactions or holdings details.

Were any CPZ shares bought or sold in this Calamos Form 3/A amendment?

No transactions are reported in this Form 3/A amendment. The transaction summary shows zero buys, zero sells, and no other share movements, indicating the filing is administrative rather than a record of recent trading activity in CPZ securities.

What insider role does John S. Koudounis hold at Calamos Long/Short Equity & Dynamic Income Trust (CPZ)?

John S. Koudounis is identified as an officer of the trust. The filing specifies his title as Vice President and also notes an additional role as trustee effective 9-1-25, reflecting his governance position with the CPZ fund.

Does the CPZ Form 3/A indicate John S. Koudounis is a 10% owner?

The filing indicates he is not a 10% owner of CPZ. It marks the ten percent owner status as zero, meaning he is reporting in his capacities as Vice President and future trustee rather than as a large equity holder.

Why is there a Form 3/A amendment for Calamos CPZ instead of a new Form 4?

This Form 3/A is an amendment to the initial ownership report, not a trade filing. It updates or clarifies insider status information, such as officer title and trustee role, and does not reflect new transactions that would typically appear on a Form 4.
