Small Caps, Big Moves: Listen to Our Approach

Opinions, estimates, forecasts, and statements of financial market trends that are based on current market conditions constitute our judgment and are subject to change without notice.

Performance data quoted represents past performance, which is no guarantee of future results. Average annual total return measures net investment income and capital gain or loss from portfolio investments as an annualized average. All performance shown assumes reinvestment of dividends and capital gains distributions. Returns of more than one year are annualized.

The chart shows the performance of the Predecessor Fund’s Institutional Class, which has been adopted by the Class I shares of the Fund for periods prior to the Reorganization. The information shows you how the Predecessor Fund’s performance has varied year by year and provides some indication of the risks of investing in the Fund. The average annual total return table compares the Predecessor Fund’s Institutional Class performance, adopted by the Fund’s Class I shares, and Class Y performance, adopted by the Fund’s Class A shares and adjusted to reflect the maximum sales load of 4.75%, to that of the Russell 2000 Growth Index. "Since Inception" return shown for the Russell 2000 Growth Index is the return since the inception of the Predecessor Fund’s Class Y shares. An index reflects no deduction for fees, expenses or taxes. To the extent that dividends and distributions have been paid by the Predecessor Fund, the performance information for the Predecessor Fund in the chart and table assumes reinvestment of dividends and distributions. If the Predecessor Fund’s investment adviser had not waived or reimbursed certain Predecessor Fund expenses during these periods, the Predecessor Fund’s returns would have been lower. As always, please note that the Fund’s past performance (before and after taxes) cannot predict how it will perform in the future.

Class I shares are offered primarily for direct investment by investors through certain tax-exempt retirement plans and by institutional clients, provided such plans or clients have assets of at least $1 million. For eligibility requirements and other available share classes see the prospectus and other Fund documents at www.calamos.com.

Morningstar Small Growth Category funds focus on faster-growing companies whose shares are at the lower end of the market-capitalization range. Stocks in the bottom 10% of the US equity market’s capitalization are defined as small caps. Growth is defined based on fast growth (high growth rates for earnings, sales, book value, and cash flow) and high valuations (high price ratios and low dividend yields). The Russell 2000® Growth Index measures the performance of the small-cap growth segment of the US equity universe. It includes those Russell 2000® companies with higher price-to-value ratios and higher forecasted growth values. The Russell 2500® Growth Index measures the performance of the small to midcap growth segment of the US equity universe. It includes those Russell 2500 companies with higher growth earning potential. Unmanaged index returns, unlike fund returns, do not reflect fees, expenses or sales charges. Investors cannot invest directly in an index.
