Performance data quoted represents past performance, which is no guarantee of future results. Current performance may be lower or higher than the performance quoted. Please refer to Important Risk Information. The principal value and return of an investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Performance reflected at NAV does not include the Fund's maximum front-end sales load of 4.75%. Had it been included, the Fund's return would have been lower.

The performance shown for periods prior to 4/6/16 is the performance of a predecessor investment vehicle (the “Predecessor Fund”). The Predecessor Fund was reorganized into the Fund on 4/6/16, 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.

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.

10k Performance is for the Fund’s Class A shares at net asset value and does not include the Fund’s maximum front-end sales charge of 4.75%—had it been included, the Fund’s return would have been lower.

Average annual total return measures net investment income and capital gain or loss from portfolio investments as an annualized average. All performance shown assumes reinvestment of dividends and capital gains distributions. Performance shown reflects an expense reimbursement that improved results. Load-adjusted returns are adjusted for the maximum front-end sales load of 2.25%* for Class A shares in the following funds: Convertible Fund, Global Convertible Fund, Market Neutral Income Fund, High Income Opportunities Fund, and Total Return Bond Fund. The maximum front-end sales load for Class A shares of all other funds is 4.75%. There is a 1% contingent deferred sales charge for C shares on certain redemptions within the first year of purchase. Class C shares have been adjusted for the contingent deferred sales charge (CDSC). There are no contingent deferred sales charges or distribution or service fees with respect to Class I shares. The minimum initial investment required to purchase each Fund's Class I shares is $1 million. Class I shares are offered primarily for direct investment by investors through certain tax-exempt retirement plans (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans, defined benefit plans and non-qualified deferred compensation plans) and by institutional clients, provided such plans or clients have assets of at least $1 million. Class I shares may also be offered to certain other entities or programs, including, but not limited to, investment companies, under certain circumstances. *Prior to 2/28/17, the Convertible Fund, Global Convertible Fund, Market Neutral Income Fund, and High Income Opportunities fund had a maximum front-end sales load of 4.75%, and the Total Return Bond Fund had a maximum front-end sales load of 3.75%.

Alpha is the measurement of performance on a risk adjusted basis. A positive alpha shows that performance of a portfolio was higher than expected given the risk. A negative alpha shows that the performance was less than expected given the risk.

Sharpe ratio is a calculation that reflects the reward per each unit of risk in a portfolio. The higher the ratio, the better the portfolio’s risk-adjusted return is.

Downside capture ratio measures manager’s performance in down markets as defined by the named index. A down-market is defined as those periods (months or quarters) in which named index return is less than 0. In essence, it tells you what percentage of the down-market was captures by the manager. For example, if the ratio is 110%, the manager has captured 110% of the down-market and therefore underperformed the market on the downside.

Upside capture ratio measures a manager’s performance in up markets relative to the named index itself. It is calculated by taking the security’s upside capture return and dividing it by the benchmark’s upside capture return.
