The performance shown for periods prior to 4/5/16 is the performance of a predecessor investment vehicle (the “Predecessor Fund”). The Predecessor Fund was reorganized into the Fund on 4/5/16, the date upon which the Fund commenced operations. On 10/1/15 the parent company of Calamos Advisors, purchased Phineus Partners LP, the prior investment adviser to the Predecessor Fund (“Phineus”), and Calamos Advisors served as the Predecessor Fund’s investment adviser between 10/1/2015 until it was reorganized into the Fund. Phineus and Calamos Advisors managed the Predecessor Fund using investment policies, objectives, guidelines and restrictions that were in all material respects equivalent to those of the Fund. Phineus and Calamos Advisors managed the Predecessor Fund in this manner either directly or indirectly by investing all of the Predecessor Fund’s assets in a master fund structure. The Predecessor Fund performance information has been adjusted to reflect Class A and I shares expenses. However, the Predecessor Fund was not a registered mutual fund and thus was not subject to the same investment and tax restrictions as the Fund. If it had been, the Predecessor Fund’s performance may have been lower.

Important Risk Information Alternative investments may not be suitable for all investors. The fund takes long positions in companies that are expected to outperform the equity markets, while taking short positions in companies that are expected to underperform the equity markets and for hedging purposes. The fund may lose money should the securities the fund is long decline in value or if the securities the fund has shorted increase in value, but the ultimate goal is to realize returns in both rising and falling equity markets while providing a degree of insulation from increased market volatility.

An investment in the Fund(s) is subject to risks, and you could lose money on your investment in the Fund(s). There can be no assurance that the Fund(s) will achieve its investment objective. Your investment in the Fund(s) is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The risks associated with an investment in the Fund(s) can increase during times of significant market volatility. The Fund(s) also has specific principal risks, which are described below. More detailed information regarding these risks can be found in the Fund's prospectus. The principal risks of investing in the Fund include: equity securities risk consisting of market prices declining in general, short sale risk consisting of potential for unlimited losses, leverage risk, and foreign securities risk. As a result of political or economic instability in foreign countries, there can be special risks associated with investing in foreign securities, including fluctuations in currency exchange rates, increased price volatility and difficulty obtaining information. In addition, emerging markets may present additional risk due to potential for greater economic and political instability in less developed countries.

The MSCI World Index is a market capitalization weighted index composed of companies representative of the market structure of developed market countries in North America, Europe and Asia/Pacific region.

The S&P 500 Index is generally considered representative of the U.S. stock market.

The HFRI Equity Hedge Index consists of funds where portfolio managers maintain long and short positions in primarily equity and derivative securities.

The Morningstar Long/Short Equity Category funds take a net long stock position, meaning the total market risk from the long positions is not completely offset by the market risk of the short positions. Total return, therefore, is a combination of the return from market exposure (beta) plus any value-added from stock picking or market-timing (alpha).

Performance data quoted represents past performance, which is no guarantee of future results. Current performance may be lower or higher than the performance quoted. The principal value and investment return of an investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost.

Unmanaged index returns assume reinvestment of any and all distributions and, unlike fund returns, do not reflect fees, expenses or sales charges. Investors cannot invest directly in an index.

Important Fund Information

  • Calamos Growth, Growth and Income, Opportunistic Value, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest in small and mid-size company securities, which generally present greater risk and higher volatility than investments in larger, more established companies.
  • Calamos Growth, Growth and Income, Opportunistic Value, Focus Growth, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds invest a substantial portion of their assets in equity securities, which are subject to greater fluctuations in market value than other asset classes as a result of such factors as a company's business performance, investor perceptions, stock market trends, and general economic conditions.
  • Calamos Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest up to 100% of assets in foreign securities. Total Return Bond Fund may invest up to 35% and all other Calamos funds up to 25% of assets in foreign securities. Investing outside the U.S. offers both risks and rewards. Increased volatility, changes in the value of foreign currencies, and difficulty in obtaining information are some of the risks involved.
  • Global Growth and Income, International Growth, Global Equity, Evolving World Growth and Total Return Bond Funds may invest in securities issued by companies in emerging markets; these may present additional risk due to the potential for greater economic and political instability in less developed countries.
  • Calamos High Income Fund invests and Total Return Bond Funds may invest in lower-rated fixed-income securities, often referred to as "junk bonds," which generally present greater risks than higher-quality securities, because of the greater likelihood that the company issuing the lower-rated securities will default on income and principal payments.
  • Calamos Growth and Income, Convertible and Market Neutral Income Funds: There are certain risks associated with an investment in a convertible bond such as a default risk—the company issuing a convertible security may be unable to repay principal and interest—and interest rate risk—the convertible may decrease in value if interest rates increase.
  • Calamos Market Neutral Income Fund engages in short sales. Short sales involve the risk that the Fund may incur a loss if the market value of a borrowed security increases between the date of the short sale and the date the Fund replaces the security. A short position in a security poses more risk than holding the same security long. Because a short position loses value as the security's price increases, the loss on a short sale is theoretically unlimited. It is possible that the market value of the securities the Fund holds in long positions will decline at the same time that the market value of the securities the Fund has sold short increases, thereby increasing the Fund's potential volatility. The Market Neutral Income Fund engages in short sales of convertible securities' underlying stock, which may increase volatility and portfolio turnover.
  • Calamos Total Return Bond Fund may invest in derivative securities, including options, futures contracts and swap agreements. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. There is no assurance that any derivative strategy used by the Fund will succeed.
  • In addition to market risk, there are certain risks associated with an investment in Calamos Total Return Bond Fund, such as default risk, the risk that the company issuing debt securities will be unable to repay principal and interest, and interest rate risk that the security may decrease in value if interest rates increase.

Performance of the Growth Fund reflects the effects of an expense reimbursement that improved results and was in effect until March 31, 2000.

Performance shown for the Convertible Fund and Global Growth and Income Fund includes the effects of an overpayment of dividends and/ or capital gains distribution to shareholders of certain classes of shares of the Fund (and a corresponding capital contribution by Calamos Advisors LLC), which increased certain return figures.

1Net asset value is the $U.S. value of a single share excluding any sales charges. NAV Change shows the change in value from the prior business day: + = gain; - = loss; NC = no change. The net asset value of a fund will fluctuate. Please note that total return is considered one of the best measures of overall performance of most mutual fund investments. More complete information and long-term performance is available for each Fund by clicking on any Fund name. Shares are redeemable at current net asset value, which may be more or less than their original cost
