The principal risks of investing in the Calamos Market Neutral Income Fund include: equity securities risk consisting of market prices declining in general, 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, synthetic convertible instruments risk, convertible hedging risk, covered call writing risk, options risk, short sale risk, interest rate risk, credit risk, high yield risk, liquidity risk, portfolio selection risk, and portfolio turnover risk.

Options Risk: The Fund’s ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed put or call option is dependent, in part, upon the liquidity of the option market. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund’s ability to utilize options successfully will depend on the ability of the Fund’s investment adviser to predict pertinent market movements, which cannot be assured.

Covered Call Writing involves selling (or “writing”) a call option against an equity the writer holds. When managers sell a call option, they earn a premium from the option sale. If the shares trade below the strike price, the option will expire worthless and they keep the premium from the option and retain the security. If the share price exceeds the strike price, the buyer will likely exercise the option and the seller must sell the shares at the strike price. To hedge additional risk, managers could also purchase put options to protect against significant equity market declines.
