Morningstar, Inc. has chosen the Calamos Market Neutral Income Fund manager
team as one of three nominees for its 2012 Alternatives Fund Manager of the
Year award in the U.S.

This is the first year for the Morningstar Alternatives Fund Manager of the
Year award. Established in 1988, the Morningstar Fund Manager of the Year
award recognizes portfolio managers who demonstrate excellent investment skill
and the courage to differ from the consensus to benefit investors. To qualify
for the award, managers' funds must have not only posted impressive returns
for the year, but the managers also must have a record of delivering
outstanding long-term risk-adjusted performance and of aligning their
interests with shareholders.

Nominated funds must be Morningstar Medalists—a fund that has garnered a
Morningstar Analyst Rating of Gold, Silver, or Bronze. The Fund Manager of the
Year award winners are chosen based on Morningstar's proprietary research and
in-depth qualitative evaluation by its fund analysts. The new five-tiered
Morningstar Analyst Rating scale has three positive levels—Gold, Silver, and
Bronze—in addition to Neutral and Negative ratings. Analysts arrive at a
rating through an evaluation of five key pillars they believe are crucial to
predicting the future success of a fund, considering both numeric as well as
qualitative factors: People, Process, Parent, Performance, and Price.
Morningstar analysts score these five pillars as Positive, Neutral, or
Negative, which are then combined for the overall rating.

Analyst Ratings are subjective in nature and should not be used as the sole
basis for investment decisions. Analyst Ratings are based on Morningstar
analysts' current expectations about future events and therefore involve
unknown risks and uncertainties that may cause Morningstar's expectations not
to occur or to differ significantly from what was expected. Morningstar does
not represent its Analyst Ratings to be guarantees nor should they be viewed
as an assessment of a fund or the fund's underlying securities
creditworthiness.

Before investing carefully consider the fund's investment objectives, risks,
charges and expenses. Please see the prospectus containing this and other
information or call 1-800-582-6959. Read it carefully.
