The Fund defines a small capitalization company as any company with a market capitalization less than or equal to that of the company with the largest market capitalization of either the Russell 2000 ? Index or the MSCI USA Small Cap Index as measured on a rolling 24-month basis over the most recent period. The market capitalization of a security is measured at the time of purchase. Equity securities in which the Fund invests as a part of its principal investment strategy consist of common stocks and American Depositary Receipts (""ADRs"").
The Fund may invest up to 25% of its net assets in foreign securities. Foreign securities are securities issued by issuers that are organized under the laws of a foreign country, that have a substantial portion of their operations or assets in a foreign country or countries, or that derive a substantial portion of their revenue or profits from businesses, investments, or sales outside of the United States. The Fund may also invest in foreign securities that are represented in the United States securities markets by ADRs or similar depositary arrangements. The Fund's foreign investments can be denominated in U.S. dollars or in foreign currencies. Calamos Advisors uses fundamental research to evaluate investment opportunities, focusing on companies that it believes have superior management and whose business models have a high potential for earnings upside.
