[1] Returns after taxes for Class I are provided because Class I shares represent the largest percentage of assets in the Calamos Family of Funds.
[2] The Fund’s investment adviser added the broad-based securities market index in accordance with regulatory disclosure requirements. The Fund continues to use the Russell 2500 Growth Index as an additional benchmark because the investment adviser believes it is more representative of the Fund’s investment universe than the broad-based securities market index. All index returns include the reinvestment of dividends and distributions net of withholding taxes, but do not reflect fees, brokerage commissions, or other expenses.
