The principal risks of investing in the Calamos Evolving World Growth Fund include: equity securities risk consisting of market prices declining in general, growth stock risk consisting of potential increased volatility due to securities trading at higher multiples, foreign securities risk, emerging markets risk, convertible securities risk consisting of the potential for a decline in value during periods of rising interest rates and the risk of the borrower to miss payments, and portfolio selection risk.

As a result of political or economic instability in foreign countries, there can be special risks associated with investing in foreign securities, including fluctuations in currency exchange rates, increased price volatility and difficulty obtaining information. In addition, emerging markets may present additional risk due to potential for greater economic and political instability in less developed countries.

The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value.

Since inception as of 6/30/16, the fund’s class A shares have a beta of 0.68 versus the MSCI Emerging Markets Index. Beta is a historic measure of a fund's relative volatility, which is one of the measures of risk; a beta of 0.5 reflects 1/2 the market's volatility, while a beta of 2.0 reflects twice the market's volatility.
