Calamos International Growth Fund Passes 5-Year Milestone

NAPERVILLE, Ill., April 19 /PRNewswire-FirstCall/ -- Calamos Investments, a leading global fund manager, today called attention to the five-year anniversary of the Calamos International Growth Fund (CIGRX) and emphasized the importance of growth-style equities in international allocations.  The fund, introduced on March 16, 2005, is an equity strategy aimed at providing long-term capital growth.

"We are pleased with the Calamos International Growth Fund's ability to serve investors over the past five years," said John P. Calamos, Sr., Chairman, CEO and Co-Chief Investment Officer.  "International investing has become more important than ever, and we believe many investors may wish to consider increasing their international allocation to growth-style equities.

"While we have seen increased interest in emerging markets and international small-cap stocks, investors seem to have paid less attention to the style of their international allocations.  One 2008 study, by InterSec Research, shows growth equity mandates accounted for only 12% of non-US equity exposure for US public and corporate pension funds.  Yet as a global fund manager, we believe fundamentals point to continued opportunity in international growth stocks."

For the one-year, three-year and five-year periods, the Calamos International Growth Fund's Class A shares at NAV ranked in the first 7% (18 out of 273 funds), 5% (11 out of 215 funds) and 4% (7 out of 158 funds), respectively, in total return in Morningstar's Foreign Large Growth category as of March 31, 2010.  Details about the fund can be found on the Calamos Web site at http://fundinvestor.calamos.com/ig_fiveyear.aspx.

The Calamos International Growth Fund invests in companies that we believe demonstrate the highest relative growth across international markets.  The Fund has a multi-cap focus, diversified across sectors and countries. The fund is managed by the same team of professionals who manage all of the investment strategies at Calamos.

"As a global fund manager, we've been investing in non-US markets for over 20 years," Calamos said.  "In the International Growth strategy we are generally looking for companies generating high returns on capital, strong cash flow and solid balance sheets that can help weather tough times if necessary. Despite anticipated slower economic growth and continued market volatility, we are finding many opportunities to pursue."
