Important Information: Calamos Aksia Alternative Credit and Income Fund

The Fund has been organized as a closed-end management investment company. Closed-end funds differ from open-end management investment companies (commonly known as mutual funds) because investors in a closed-end fund do not have the right to redeem their shares on a daily basis. Unlike most closed-end funds, which typically list their shares on a securities exchange, the Fund does not currently intend to list the shares for trading on any securities exchange, and the Fund does not expect any secondary market to develop for the shares in the foreseeable future. Therefore, an investment in the Fund, unlike an investment in a typical closed-end fund, is not a liquid investment.

Risk Factors: General Economic Conditions and Recent Events. Difficult global credit market conditions may adversely affected the market values of equity, fixed-income, hard assets, and other securities and these circumstances may continue or even deteriorate further. Investments made by the Fund are expected to be sensitive to the performance of the overall economy.

Lending. The value of the Fund's assets is volatile and may fluctuate due to a variety of factors that are inherently difficult to predict and a re outside the control of the Advisor and Sub-Advisors, including prevailing credit spreads, general economic conditions, financial market conditions, domestic or international economic or political events, developments or trends in any particular industry, changes in interest rates, or the financial condition of the obligors of the Fund's assets.

Direct Origination. A significant portion of the Fund's investments may be originated. The results of the Fund's operations depend on several factors, including the availability of opportunities for the origination or acquisition of target investments, the level and volatility of interest rates, the availability of adequate short and long-term financing, conditions in the financial markets and economic conditions.

Loans. Loan interests generally are subject to restrictions on transfer, and the Fund may be unable to sell loan interests at a time when it may otherwise be desirable to do so or may be able to sell them only at prices that are less than what the Fund regards as their fair market value.

Secured Debt. Secured debt in most circumstances is fully collateralized by assets of the borrower. However, there is a risk that the collateral securing the Fund's loans may decrease in value over time, may be difficult to sell in a timely manner, may be difficult to appraise, and may fluctuate in value based upon the success of the business and market conditions, including as a result of the inability of the borrower to raise additional capital.

High Yield, Low-Rated or Unrated Securities. Debt securities (including bonds) and preferred stock in which the Fund invests may or may not be rated by credit rating agencies. The values of lower-rated securities (including unrated securities of comparable quality) fluctuate more than those of higher-rated securities because investors generally believe that there are greater risks associated with them.

Unsecured Loans. The Fund may make unsecured loans to borrowers, meaning that such loans will not benefit from any interest in collateral of such borrowers. Liens on such a borrower's collateral, if any, will secure the borrower's obligations under its outstanding secured debt and may secure certain future debt that is permitted to be incurred by the borrower under its secured loan agreements. The holders of obligations secured by such liens will generally control the liquidation of, and be entitled to receive proceeds from, any realization of such collateral to repay their obligations in full before the Fund.
