Important Fund Information

Leverage creates risks which may adversely affect return, including the likelihood of greater volatility of net asset value and market price of common shares; and fluctuations in dividend rates on any preferred shares.

The use of swap transactions involves investments techniques and risks that are different from those associated with portfolio security transactions. If Calamos is incorrect in its forecasts of market values, interest rates, and other applicable factors, the investment performance of the Fund will be less favorable than if those techniques had not been used. Those instruments are typically not traded on exchanges. Accordingly, there is risk that the other party to certain of these instruments will not perform its obligations to the Fund or that the Fund may be unable to enter into offsetting positions to terminate its exposure or liquidate its position under certain of these instruments when it wishes to do so. Such occurrences could result in losses to the Fund.
