NAPERVILLE, Ill., Jan. 3, 2013 /PRNewswire/ -- Calamos Investments ®* announces the Calamos Growth and Income Fund (A Shares: CVTRX; C Shares: CVTCX; I Shares: CGIIX) and the Calamos Global Growth and Income Fund (A Shares: CVLOX; C Shares: CVLCX; I Shares: CGCIX) are reopened to new accounts and new investments as of January 2, 2013. "We are pleased that the Calamos Growth and Income Fund and Calamos Global Growth and Income Fund are again open to new investors. The Calamos Growth and Income Fund and Calamos Global Growth and Income Fund are actively managed funds that offer upside participation in the equity market with historically less exposure to the downside than equity-only portfolios over full market cycles," said John P. Calamos, Sr., Chief Executive Officer and Global Co-Chief Investment Officer of Calamos Investments. "Since their inceptions, each of these funds has exhibited lower volatility by employing a flexible approach utilizing primarily equity-linked and convertible securities to respond to changing, volatile markets and investment opportunities. Guided by the best interests of our current fund shareholders, Calamos has continued to evaluate market opportunities consistent with each fund's investment objective and strategy, and to navigate the current equity market volatility based on managing a consistent risk/reward profile. As global economic recovery has continued and equity markets trend up, our team is seeing increased opportunities in the convertible market. The funds' flexibility to create synthetic convertibles also enhances the opportunity to achieve the funds' investment objectives. At this time we believe that reopening the funds allows us to seek to take advantage of a broader opportunity set that reflects our top-down macro view going into 2013," said Calamos. The Calamos Growth and Income Fund and the Calamos Global Growth and Income Fund have demonstrated less volatility over the history of the funds as measured by beta, managing risk and reward over the course of many market cycles. The funds invest in a combination of instruments, including equity-linked and convertible securities, synthetic convertibles, stocks and fixed income to seek to achieve each fund's investment objective and risk/reward for current market conditions.
