Portfolio Turnover [Heading] Portfolio Turnover
Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example, affect the Fund’s performance.

The Fund’s portfolio turnover rate is not available as the Fund had not commenced investment operations as of the date of this prospectus. The portfolio turnover rate of the Calamos Timpani SMID Growth Fund (the “Predecessor Fund”) was 192% for the fiscal year ended October 31, 2025.
