TAX CENTER

Capital gains are the result of the Funds' sale of securities that have appreciated in price. The investment management team may sell assets that have had price gains when the team believes the securities are no longer appropriately valued. Securities that have appreciated in value may also be sold to maintain an appropriate level of diversification within the portfolio.

Our main focus at Calamos is to position our Funds to pursue the highest long-term total returns with an appropriate amount of risk, based on each Fund's investment objective. We are always tax aware and we attempt to mitigate annual taxable gains in our portfolios when prudent. For individuals, long-term capital gains are taxed at a maximum rate of 15%; while short-term gains (gains on securities held for one year or less) are generally taxed at your ordinary income rate, and are therefore included with the ordinary income distribution found in box 1a of your Form 1099-DIV.
