President's Letter

(JOHN P. CALAMOS, SR. PHOTO)

Dear Shareholder:

Thank you for your interest in the Calamos Family of Funds, as we welcome the
opportunity to be a part of your long-term financial plan. Inside this
semi-annual report you will find performance, sector allocation, holdings and
financial highlights for all of Calamos Investment Trust portfolios, including
the newest portfolio, the Calamos International Growth Fund.

Here at Calamos Investments, we manage all of our funds to seek solid long-term
risk-adjusted performance. One of the keys to our investment process is to
concentrate not on short-term market fluctuations, but to position our
portfolios for where we believe the market is headed, not where it has been.
Although our family of funds range from more aggressive to more conservative
investment approaches, each portfolio's holding is assessed on its potential
downside versus its upside, and then adjusted when necessary in anticipation of
our economic and market outlook. Currently, we believe that we are in the middle
phase of the economic cycle, and have strived to position each portfolio for a
period of slow, but stable growth, generally favoring higher quality,
often larger-sized companies.

We consider our communications to shareholders to be a critical part of our
customer service orientation and urge you to review the quarterly fund reviews
and market commentaries for further information regarding our outlook and
positioning. Remember that our Web site (www.calamos.com) can provide you with
market updates, current fund performance, portfolio information and more. For
example, we have recently added a tax center to assist you as tax season
approaches. The center includes fund income and capital gain distributions,
qualified dividend data, a tax calendar and a guide to tax forms. All data will
be updated for 2005 as it becomes available.

If you have any questions about your account or investment, you can contact your
financial advisor, visit us at www. calamos.com or contact a Calamos Client
Service Representative at 800.582.6959 Monday thorough Friday, 8 a.m. to 6 p.m
(Central Time). Once again, thank you for your confidence in Calamos Investments
and the Calamos Family of Funds. We look forward to being part of your long-term
investment plan in the months and years ahead.

Sincerely,


/s/ JOHN P. CALAMOS, SR.

                                September 4, 1990

As of 09/30/2005, Morningstar rated the Calamos Growth Fund three stars for
three years, four stars for five years, and five stars for 10 years out of 655,
464 and 166 mid-cap growth funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the Growth Fund includes the effects of an overpayment of
dividends and/or capital gains distributions to shareholders of certain share
classes of the Fund (and a corresponding capital contribution by Calamos Asset
Management, Inc., the predecessor to Calamos Advisors LLC), which increased
certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2000. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent
     deferred sales charge (CDSC).

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.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2004. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent
     deferred sales charge (CDSC).

As of 09/30/2005, Morningstar rated the Calamos Value Fund three stars for three
years out of 1,227 large blend funds.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2004. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent
     deferred sales charge (CDSC).

                                September 9, 1996

As of 09/30/2005, Morningstar rated the Calamos Global Growth and Income Fund
two stars for three years and four stars for five years out of 304 and 224 world
stock funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the Global Growth and Income Fund includes the effects of an
overpayment of dividends and/or capital gains distributions to shareholders of
certain share classes of the Fund (and a corresponding capital contribution by
Calamos Asset Management, Inc., the predecessor to Calamos Advisors LLC), which
increased certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2004. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent
     deferred sales charge (CDSC).

                               September 22, 1988

As of 09/30/2005, Morningstar rated the Calamos Growth and Income Fund three
stars for three years, four stars for five years and five stars for 10 years out
of 63, 56 and 33 convertible funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the Growth and Income Fund includes the effects of an overpayment
of dividends and/or capital gains distributions to shareholders of certain share
classes of the Fund (and a corresponding capital contribution by Calamos Asset
Management, Inc., the predecessor to Calamos Advisors LLC), which increased
certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Load-adjusted
     returns are adjusted for the maximum front-end sales load of 4.75% for
     Class A shares and returns for Class B and C shares have been adjusted for
     the contingent deferred sales charge (CDSC).

                                 August 1, 1999

As of 09/30/2005, Morningstar rated the Calamos High Yield Fund three stars for
three years and four stars for five years out of 361 and 297 high yield bond
funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the High Yield Fund includes the effects of an overpayment of
dividends and/or capital gains distributions to shareholders of certain share
classes of the Fund (and a corresponding capital contribution by Calamos Asset
Management, Inc., the predecessor to Calamos Advisors LLC), which increased
certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2004. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent
     deferred sales charge (CDSC).

                                    INCEPTION
                                  June 21, 1985

As of 09/30/2005, Morningstar rated the Calamos Convertible Fund two stars for
three years, four stars for five years and five stars for 10 years out of 63, 56
and 33 convertible funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the Convertible Fund includes the effects of an overpayment of
dividends and/or capital gains distributions to shareholders of certain share
classes of the Fund (and a corresponding capital contribution by Calamos Asset
Management, Inc., the predecessor to Calamos Advisors LLC), which increased
certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Load-adjusted
     returns are adjusted for the maximum front-end sales load of 4.75% for
     Class A shares and returns for Class B and C shares have been adjusted for
     the contingent deferred sales charge (CDSC).

                                September 4, 1990

As of 09/30/2005, Morningstar rated the Calamos Market Neutral Fund two stars
for three years, four stars for five years, and four stars for 10 years out of
252, 165 and 66 conservative allocation funds, respectively.

Morningstar ratings are for Class A shares; the other classes may have different
performance characteristics. For each U.S.-domiciled fund with at least a three
year history, Morningstar calculates a Morningstar Rating(TM) based on a
Morningstar risk-adjusted return measure that accounts for variation in a fund's
monthly performance (including the effects of sales charges, loads and
redemption fees), placing more emphasis on downward variations and rewarding
consistent performance. The top 10% of funds in each category receive five
stars, the next 22.5% receive four stars, the next 35% receive three stars, the
next 22.5% receive two stars and the bottom 10% receive one star. (Each share
class is counted as a fraction of one fund within this scale and rated
separately, which may cause slight variations in the distribution percentages.)

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.

Performance of the Market Neutral Fund includes the effects of an overpayment of
dividends and/or capital gains distributions to shareholders of certain share
classes of the Fund (and a corresponding capital contribution by Calamos Asset
Management, Inc., the predecessor to Calamos Advisors LLC), which increased
certain return figures.

+    Average annual total return measures net investment income and capital gain
     or loss from portfolio investments as an annualized average assuming
     reinvestment of dividends and capital gains distributions. Performance
     shown reflects the effects of an expense reimbursement that improved
     results and was in effect until March 31, 2000. Load-adjusted returns are
     adjusted for the maximum front-end sales load of 4.75% for Class A shares
     and returns for Class B and C shares have been adjusted for the contingent

                                Calamos Market Neutral Fund SEMIANNUAL REPORT 19



Expense Overview

As a shareholder of a mutual fund, you incur two types of costs. You incur:

1) Transaction costs, including sales charges or loads, on purchase payments, or
other distributions.

2) Ongoing costs, including management fees, distribution and/or service (12b-1)
fees and other fund expenses.

The examples in this report are based on an investment of $1,000 made at the
beginning of the period and held for the entire period from April 1, 2005 to
September 30, 2005. It is intended to help you understand the ongoing cost
associated with investing in each mutual fund and to compare these costs with
the ongoing costs of investing in other mutual funds.

There are two parts of each Fund's chart:

ACTUAL

In this part of the chart, you'll see the actual expenses you would have on a
$1,000 investment made at the beginning of the period and held for the entire
period in each fund from April 1, 2005 to September 30, 2005, the period covered
by this report. This chart also shows the actual returns, after expenses, you
would have earned during that time. This chart can help you estimate your own
expenses. For example, if you invested $8,600 in Class A shares of the fund,
simply divide $8,600 by $1,000, then multiply that result by the figure in the
"Actual Expenses per $1,000" row. (In this example, you would multiply 8.6 by
the figure.)

HYPOTHETICAL

In this part of the chart, you'll see the hypothetical expenses you would have
paid on $1,000 investment from April 1, 2005 to September 30, 2005, and the
hypothetical returns, after expenses, you would have earned during that time.
The Securities and Exchange Commission (SEC) has established the guidelines for
this chart, including the 5% annual return before expenses, which is what you'll
see in the chart. Note that this chart will not help you determine your own
expenses, but will help you compare expenses of the fund you own to the expenses
of another fund since the information for that fund should be calculated using
the same assumptions.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not include any transactional costs, such as sales
charges (loads), redemption fees or exchange fees. Therefore, the second line of
the table is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION. CALAMOS INVESTMENT TRUST, a Massachusetts business trust organized
December 21, 1987 (the "Trust"), consists of nine series, CALAMOS Growth Fund,
CALAMOS Blue Chip Fund, CALAMOS Value Fund, CALAMOS International Growth Fund,
CALAMOS Global Growth and Income Fund, CALAMOS Growth and Income Fund, CALAMOS
High Yield Fund, CALAMOS Convertible Fund, and CALAMOS Market Neutral Fund (the
"Funds"). Each fund is registered under the Investment Company Act of 1940 as a
diversified, open-end management investment company. The Trust currently offers
Class A, Class B, Class C and Class I shares of each of the Funds. The CALAMOS
Convertible Fund and CALAMOS Market Neutral Fund are closed to all new
investments, subject to the exceptions enumerated in the Prospectus.

PORTFOLIO VALUATION. In computing the net asset value of the Funds, portfolio
securities that are traded on a securities exchange in the United States, except
an option security, are valued at the last reported sale price as of the time of
valuation, or lacking any current reported sale at the time of valuation, at the
mean between the most recent bid and asked quotations. Each option security
traded on a securities exchange in the United States is valued at the last
current reported sale price as of the time of valuation if the last current
reported sale price falls within the consolidated bid/ask quote for the option
security. If the last current reported sale price as of the time of valuation
does not fall within the consolidated bid/ask quote for the option security, the
security is valued at the mid-point of the consolidated bid/ask quote for the
option security. Each security traded in the over-the-counter market and quoted
on the NASDAQ National Market System, is valued at the NASDAQ Official Closing
Price ("NOCP"), as determined by NASDAQ, or lacking an NOCP, the last current
reported sale price as of the time of valuation by NASDAQ, or lacking any
current reported sale on NASDAQ at the time of valuation, at the mean between
the most recent bid and asked quotations. Each over-the-counter option that is
not traded through the Options Clearing Corporation is valued by the
counterparty, or if the counterparty's price is not readily available then by
using the Black-Scholes method. Each other security traded over-the-counter is
valued at the mean between the most recent bid and asked quotations. Short-term
securities with maturities of 60 days or less are valued at amortized cost,
which approximates market value.

When market quotations are not readily available or when the valuation methods
mentioned above are not reflective of the fair value of the security, the
security is priced at a fair value following procedures and/or guidelines
approved by the Board of Trustees, which may include utilizing a systematic fair
valuation model provided by an independent pricing system. The Funds' may also
use fair value pricing, if the value of a security it holds is, pursuant to
Board of Trustees' guidelines, materially affected by events occurring before
the Funds' pricing time but after the close of the primary market or exchange on
which the security is traded. These procedures may utilize valuations furnished
by pricing services approved by the Board of Trustees, which may be based on
market transactions for comparable securities and various relationships between
securities that are generally recognized by institutional traders, a
computerized matrix system, or appraisals derived from information concerning
the securities or similar securities received from recognized dealers in those
securities. When fair value pricing is employed, the value of the portfolio
security used to calculate the Funds' net asset value may differ from quoted or
official closing prices.

Securities that are principally traded in a foreign market are valued at the
last current sale price at the time of valuation or lacking any current or
reported sale, at the time of valuation, at the mean between the most recent bid
and asked quotations as of the close of the appropriate exchange or other
designated time. Trading in securities on European and Far Eastern securities
exchanges and over-the-counter markets is normally completed at various times
before the close of business on each day on which the New York Stock Exchange
("NYSE") is open. Trading of these securities may not take place on every NYSE
business day. In addition, trading may take place in various foreign markets on
Saturdays or on other days when the NYSE is not open and on which the Fund's net
asset value is not calculated. As stated above, if the market prices are not
readily available or are not reflective of the fair value of the security, the
security will be priced at a fair value following procedures approved by the
Board of Trustees. In light of the judgment involved in fair value decisions,
there can be no assurance that a fair value assigned to a particular security is
accurate.


                              Notes to Financial Statements SEMIANNUAL REPORT 61



NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

INVESTMENT TRANSACTIONS AND INVESTMENT INCOME. Short-term investment
transactions are recorded on a trade date basis. Long-term investment
transactions are recorded on a trade date plus one basis, except for fiscal
quarter ends, which are recorded on trade date. Net realized gains and losses
from investment transactions are reported on an identified cost basis. Interest
income is recognized using the accrual method and includes accretion of original
issue and market discount and amortization of premium. Dividend income is
recognized on the ex-dividend date, except that certain dividends from foreign
securities are recorded as soon as the information becomes available.

FOREIGN CURRENCY TRANSLATION. Except for securities of foreign issuers valued by
a pricing service, values of investments and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars using a rate
quoted by a major bank or dealer in the particular currency market, as reported
by a recognized quotation dissemination service.

The Funds do not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign currency gains or losses arise from disposition of
foreign currency, foreign currency gains or losses realized between the trade
and settlement dates on securities transactions, and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Funds' books on the transaction date and the U.S. dollar equivalent of the
amounts actually received or paid. Net unrealized foreign exchange gains and
losses arise from changes (due to the changes in the exchange rate) in the value
of foreign currency and other assets and liabilities denominated in foreign
currencies held at period end.

OPTION TRANSACTIONS. For hedging and investment purposes, the Funds may purchase
or write (sell) put and call options. One of the risks associated with
purchasing an option among others, is that each Fund pays a premium whether or
not the option is exercised. Additionally, each of the Funds bear the risk of
loss of premium and change in market value should the counterparty not perform
under the contract. Put and call options purchased are accounted for in the same
manner as portfolio securities. The cost of securities acquired through the
exercise of call options is increased by premiums paid. The proceeds from
securities sold through the exercise of put options are decreased by the
premiums paid.

When a Fund writes an option, an amount equal to the premium received by a Fund
is recorded as a liability and is subsequently adjusted to the current value of
the option written. Premiums received from writing options that expire
unexercised are treated by a Fund on the expiration date as realized gains from
investments. The difference between the premium and the amount paid on effecting
a closing purchase transaction, including brokerage commissions, is also treated
as a realized gain, or, if the premium is less than the amount paid for the
closing purchase transaction, as a realized loss. If a written call option is
exercised, the premium is added to the proceeds from the sale of the underlying
security or currency in determining whether a Fund has realized a gain or loss.
If a written put option is exercised, the premium reduces the cost basis of the
securities purchased by a Fund. A Fund as writer of an option bears the market
risk of an unfavorable change in the price of the security underlying the
written option.

ALLOCATION OF EXPENSES BETWEEN CLASSES. Expenses directly attributable to a Fund
are charged to that Fund; other expenses of the Trust are allocated
proportionately among each of the Funds within the Trust in relation to the net
assets of each Fund or on another reasonable basis. Expenses directly
attributable to a particular class of a Fund are charged directly to such class.
In calculating the net asset value per share of each class, investment income,
realized and unrealized gains and losses and expenses other than class specific
expenses are allocated daily to each class of shares based upon the proportion
of net assets of each class at the beginning of each day plus current day fund
share activity.

USE OF ESTIMATES. The preparation of financial statements in conformity with
U.S. generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results may differ from those
estimates.

INCOME TAXES. No provision has been made for income taxes because the Trust's
policy is to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute to shareholders substantially all of its
taxable income and gains.

                                       NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

Dividends and distributions paid to shareholders are recorded on the ex-dividend
date. The amount of dividends and distributions from net investment income and
net realized capital gains is determined in accordance with federal income tax
regulations, which may differ from U.S. generally accepted accounting
principles. To the extent these "book/tax" differences are permanent in nature
such amounts are reclassified within the capital accounts based on their federal
tax-basis treatment. These differences are primarily due to differing treatments
for foreign currency transactions, contingent payment debt instruments and
methods of amortizing and accreting on fixed income securities. The Funds also
may treat a portion of the proceeds from each redemption of capital shares as a
distribution of taxable net investment income and/or realized capital gain.
Financial records are not adjusted for temporary differences.

INDEMNIFICATIONS. Under the Funds' organizational documents, its Officers and
Trustees are indemnified against certain liabilities arising out of the
performance of their duties to the Funds. In addition, in the normal course of
business, the Trust enters into contracts that provide general indemnifications
to other parties. Each Funds' maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against each Fund
that have not yet occurred. However, the Funds have not had prior claims or
losses pursuant to these contracts and expect the risk of loss to be remote.

NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER
PARTIES

Pursuant to an investment advisory agreement with Calamos Advisors LLC ("Calamos
Advisors"), each Fund pays a monthly investment advisory fee based on the
average daily net assets of each Fund, computed as follows: The Growth and
Income Fund, Convertible Fund, and Market Neutral Fund fees are at the annual
rate of 0.75% of the first $500 million of average daily net assets, 0.70% of
the next $500 million of average daily net assets, 0.65% of average daily net
assets in excess of $1 billion. The High Yield Fund fee is at the annual rate of
0.75% of the Fund's average daily net assets. The Growth Fund pays a fee at the
annual rate of 1.00% of the first $500 million of the Growth Fund's average
daily net assets, .90% of the next $500 million of average daily net assets,
..80% of the next $5 billion of average daily net assets (average daily net
assets in excess of $1 billion to $6 billion), .78% of the next $5 billion of
average daily net assets (average daily net assets in excess of $6 billion to
$11 billion), .76% of the next $5 billion of average daily net assets (average
daily net assets in excess of $11 billion to $16 billion), .74% of the next $5
billion of average daily net assets (average daily net assets in excess of $16
billion to $21 billion), .72% of the next $5 billion of average daily net assets
(average daily net assets in excess of $21 billion to $26 billion) and .70% of
average daily net assets in excess of $26 billion. The Blue Chip Fund, Value
Fund, and Global Growth and Income Fund fees are at the annual rate of 1.00% of
each Fund's average daily net assets.

The International Growth Fund pays a fee based on average daily net assets of
the Fund that is accrued daily and paid on a monthly basis, except for the
performance fee, which will be accrued and paid on a monthly basis beginning in
March 2006. The performance adjustment equally increases or decreases the
management fee, on a monthly basis, by 1/12 of 0.03% of the Fund's average daily
net assets for each full 1% increment amount by which the Fund outperforms or
underperforms the MSCI EAFE Growth Index ("Index") on an annualized basis,
respectively. The base fee is at the annual rate of 1.00% of the first $500
million of International Growth Fund's average daily net assets, 0.95% of the
next $500 million of average daily net assets, 0.90% of the next $5 billion of
average daily net assets (average daily net assets in excess of $1 billion to $6
billion), 0.88% of the next $5 billion of average daily net assets (average
daily net assets in excess of $6 billion to $11 billion), 0.86% of the next $5
billion of average daily net assets (average daily net assets in excess of $11
billion to $16 billion), 0.84% of the next $5 billion of average daily net
assets (average daily net assets in excess of $16 billion to $21 billion), 0.82%
of the next $5 billion of average daily net assets (average daily net assets in
excess of $21 billion to $26 billion) and 0.80% of average daily net assets in
excess of $26 billion.

The performance adjustment rate is calculated by comparing over the performance
period the Fund's performance to that of the Index. The performance period for
International Growth Fund commenced at the beginning of its first full month of
operation and will eventually include 36 months. Starting with twelfth month,
the performance adjustment takes effect. Each month subsequent to the twelfth
month, new month is added to the performance period until the performance period
includes 36 months. Thereafter, the performance period consists of the most
recent month plus the previous 35 months.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

The performance comparison is made at the end of each month. The maximum
annualized performance adjustment rate is +/-0.30% of International Growth
Fund's average daily net assets over the performance period. The performance
adjustment rate is divided by twelve and multiplied by the Fund's average daily
net assets over the performance period, and the resulting dollar amount is then
added to or subtracted from the base fee. CALAMOS ADVISORS may receive a
positive performance adjustment even if the Fund has a negative return over a
performance period if it otherwise outperforms the Index during that period.

Calamos Advisors receives a fee payable monthly at the annual rate of 0.0175% on
the first $1 billion of combined assets; 0.0150% on the next $1 billion of
combined assets; and 0.0110% on combined assets above $2 billion for financial
accounting services. For purposes of this calculation combined assets means the
net assets of Calamos Investment Trust, Calamos Advisors Trust, and the managed
net assets of Calamos Convertible and High Income Fund, Calamos Strategic Total
Return Fund, and Calamos Convertible Opportunities and Income Fund. Financial
accounting services include, but are not limited to, the following: managing
expenses and expense payment processing; monitoring the calculation of expense
accrual amounts; calculating, tracking, and reporting tax adjustments on all
assets and monitoring trustee deferred compensation plan accruals and
valuations. The Funds pay their pro rata share of the financial accounting
services fee payable to Calamos Advisors based on average net assets of the
Funds.

Effective August 1, 2005, the Trust began reimbursing the advisor for
compensation paid to the Chief Compliance Officer of the Trust. This
compensation is reported as part of "Other" expenses on the Statement of
Operations.

Calamos Advisors has contractually agreed to limit the annual ordinary operating
expenses of each Fund, as a percentage of the average daily net assets of the
particular class of shares, to 1.75% for Class A shares, 2.50% for Class B
shares, 2.50% for Class C shares, and 1.50% for Class I shares through August
31, 2006. As of September 30, 2005, there were no expenses waived or absorbed.

As Distributor, CALAMOS FINANCIAL SERVICES LLC ("CFS") assumed all expenses of
personnel, office space, office facilities and equipment incidental to such
service. Each Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under
the Investment Company Act of 1940 whereby the Fund pays to CFS an annual
distribution and/or service fee of 0.25% of the average daily net assets of the
Fund's Class A shares and an annual service fee of 0.25% and an annual
distribution fee of 0.75% of the average daily net assets of the Fund's Class B
shares and Class C shares.

CFS also receives a sales commission and/or an underwriting fee on certain sales
of each Fund's Class A shares. During the six months ended September 30, 2005,
CFS received commissions and distribution fees of $2,211,818, $15,820, $15,355
$41,446, $61,291, $881,282 and $31,533 from the sale of shares of Growth Fund,
Blue Chip Fund, Value Fund, International Growth Fund, Global Growth and Income
Fund, Growth and Income Fund and High Yield Fund, respectively.

Furthermore, pursuant to an agreement with US Bancorp Fund Services, LLC, the
Funds' transfer agent ("US Bancorp"), CFS provides certain shareholder
administrative services to US Bancorp. Effective as of September 1, 2005, CFS
will receive an annual fee of $175,000, paid in monthly installments, for
providing of these services. Also, US Bancorp pays license fees to unaffiliated
third parties for CFS' utilization of certain transfer agent and phone systems
in the providing of these services. The fees paid to CFS and the payment of
license fees to third parties are borne by US Bancorp. The Funds have not
assumed or incurred any additional expenses in connection with CFS providing
these services to US Bancorp and the transfer agency fees payable by the Funds
to US Bancorp have not increased as a result thereof.

Certain officers and trustees of the Trust are also officers and directors of
CFS and Calamos Advisors. All officers and affiliated trustees serve without
direct compensation from the Trust. The Funds' Statement of Additional
Information contains additional information about the Funds' trustees and is
available upon request without charge by calling our toll free number (800)
582-6959.

Certain affiliates of the advisor hold material investments in the Funds. As of
September 30, 2005 affiliates of the advisor held 15%, 17% and 49% of the
outstanding shares for the Blue Chip Fund, Value Fund and International Growth
Fund, respectively.

The Trust has adopted a deferred compensation plan (the "Plan"). Under the Plan,
a trustee who is not an "interested person" of Calamos Advisors and has elected
to participate in the Plan (a "participating trustee") may defer receipt of all
or a portion of his compensation from the Trust. The deferred compensation
payable to the participating trustee is credited to the trustee's deferral
account as of the business day such compensation would have been paid to the
participating trustee. The value of a participating trustee's deferred

                                       NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

compensation account at any time is equal to what would be the value if the
amounts credited to the account had instead been invested in shares of one or
more of the Funds of the Calamos Investment Trust as designated by the trustee.
Thus, the value of the account increases with contributions to the account or
with increases in the value of the measuring shares, and the value of the
account decreases with withdrawals from the account or with declines in the
value of the measuring shares. If a participating trustee retires, the trustee
may elect to receive payments under the plan in a lump sum or in equal
installments over a period of five years. If a participating trustee dies, any
amount payable under the Plan will be paid to the trustee's beneficiaries.
Deferred compensation investments of $38,429 for the Growth Fund, $13,360 for
the Blue Chip Fund, $21,263 for the Value Fund, $4,289 for the International
Growth Fund, $23,751 for the Global Growth and Income Fund, $28,421 for the
Growth and Income Fund, $23,636 for the High Yield Fund, $24,543 for the
Convertible Fund and $23,871 for the Market Neutral Fund are included in "Other
assets" on the Statements of Assets and Liabilities at September 30, 2005. Each
Fund's obligation to make payments under the Plan is a general obligation of
that Fund and is included in "Accounts payable and accrued liabilities" on the
Statement of Assets and Liabilities at September 30, 2005.

NOTE 5 - SHORT SALES

Securities sold short represent obligations to purchase the securities at a
future date at then prevailing prices. A Fund may sell a security it does not
own in anticipation of a decline in the fair value of that security. When a Fund
sells a security short, it must borrow the security sold short and deliver it to
the broker-dealer through which it made the short sale. Dividends paid on
securities sold short are disclosed as an expense on the statement of
operations. A gain, limited to the price at which the Fund sold the security
short, or a loss, unlimited in size, will be recognized upon the termination of
a short sale.

So long as the short position is open, the Fund must adjust daily the value of
the segregated account so that the amount deposited in it, plus any amount
deposited with the broker as collateral, will equal the current market value of
the security sold short. However, the value of the segregated account may not be
reduced below the point at which the segregated account, plus any amount
deposited with the broker, is equal to the market value of the securities sold
short at the time they were sold short.

NOTE 6 - FORWARD FOREIGN CURRENCY CONTRACTS

Each Fund may engage in portfolio hedging with respect to changes in currency
exchange rates by entering into foreign currency contracts to purchase or sell
currencies. A forward foreign currency contract is a commitment to purchase or
sell a foreign currency at a future date at a negotiated forward rate. Risks
associated with such contracts include, among other things, movement in the
value of the foreign currency relative to the U.S. dollar and the ability of the
counterparty to perform. The net unrealized gain, if any, represents the credit
risk to the Fund on a forward foreign currency contract. The contracts are
valued daily at forward exchange rates and an unrealized gain or loss is
recorded. The Fund realizes a gain or loss upon settlement of the contracts. The
counterparty to all forward foreign currency contracts at September 30, 2005,
was a multinational bank.

NOTE 7 - SYNTHETIC CONVERTIBLE SECURITIES

The Funds may establish a "synthetic" convertible instrument by combining
separate securities that possess the economic characteristics similar to a
convertible security, i.e., fixed-income securities ("fixed-income component")
and the right to acquire equity securities ("convertible component"). The
fixed-income component is achieved by investing in non-convertible, fixed income
securities such as bonds, preferred stocks and money market instruments. The
convertible component is achieved by investing in warrants or options to buy
common stock at a certain exercise price, or options on a stock index. In
establishing a synthetic instrument, the Funds may pool a basket of fixed-income
securities and a basket of warrants or options that produce the economic
characteristics similar to a convertible security. Within each basket of
fixed-income securities and warrants or options, different companies may issue
the fixed-income and convertible components, which may be purchased separately
and at different times.

The Funds may purchase synthetic securities created by other parties, typically
investment banks, including convertible structured notes. Convertible structured
notes are fixed-income debentures linked to equity. Convertible structured notes
have the attributes of a convertible security; however, the investment bank that
issued the convertible note assumes the credit risk associated with the
investment, rather than the issuer of the underlying common stock into which the
note is convertible. Purchasing synthetic convertible securities may offer more
flexibility than purchasing a convertible security. Different companies may
issue the fixed-income and convertible components, which may be purchased
separately and at different times.

NOTE 8 - SECURITIES LENDING

For the six months ended September 30, 2005 the Funds loaned certain of its
securities to broker-dealers and banks. Any such loan must be continuously
secured by collateral in cash or cash equivalents maintained on a current basis
in an amount at least equal to the market value of the securities loaned by the
Funds. The Funds continue to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned and also receive an additional
return that may be in the form of a fixed fee or a percentage of the collateral.
The Funds may pay reasonable fees to persons unaffiliated with the Funds for
services in arranging these loans. The Funds have the right to call the loan and
obtain the securities loaned at any time on notice of not more than five
business days. The Funds do not have the right to vote the securities during the
existence of the loan but could call the loan in an attempt to permit voting of
the securities in certain circumstances. Upon return of the securities loaned,
the cash or cash equivalent collateral will be returned to the borrower. In the
event of bankruptcy or other default of the borrower, the Funds could experience
both delays in liquidating the loan collateral or recovering the loaned
securities and losses, including (a) possible decline in the value of the
collateral or in the value of the securities loaned during the period while the
Funds seek to enforce its rights thereto, (b) possible subnormal levels of
income and lack of access to income during this period, and (c) the expenses of
enforcing their rights. In an effort to reduce these risks, Calamos Advisors LLC
and the security lending agent will monitor the creditworthiness of the firms to
which the Fund lends securities. At September 30, 2005, the Growth Fund, Blue
Chip Fund, Value Fund, Global Growth and Income Fund, Growth and Income Fund,
High Yield Fund, and Convertible Fund had securities valued at $2,411,009,112,
$21,908,497, $20,505,763, $40,303,258, $676,068,329, $44,737,085, and,
$179,084,825, respectively, on loan to broker-dealers and banks and Growth Fund,
Blue Chip Fund, Value Fund, Global Growth and Income Fund, Growth and Income
Fund, High Yield and Convertible Fund had $2,451,221,285, $22,489,467,
$21,163,297, $41,175,859, $693,063,438, $45,865,015 and $183,084,217,
respectively, in cash collateral.

NOTE 9 - REDEMPTION FEE

A redemption of Class A, Class B, Class C and Class I shares of a Fund (except
shares purchased with reinvested dividends or distributions) held for five days
or less may be subject to a redemption fee of 2% of the redemption proceeds that
will be deducted from those proceeds. The redemption fee is intended to deter
short-term trading. The redemption fee is also intended to offset portfolio
transaction costs, market impact, and other costs associated with short-term
trading. If the shares redeemed were purchased on different days, the shares
held shortest will be redeemed first for purposes of determining whether the
redemption fee applies. The redemption fee is not a sales charge; it is retained
by the Fund and reflected as an addition to paid in capital and does not benefit
the Funds Advisor or any other third party.

For the six months ended September 30, 2005, the redemption fees collected by
the Funds were as follows:

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     shares nor the contingent deferred sales charge for Class B and C shares
     and does not reflect the deduction of taxes that a shareholder would pay on
     fund distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital contribution by
     Calamos Advisors. Excluding this item, total return would have been
     -14.19%, -20.64%, -14.76%, and -13.92% for Class A, Class B, Class C and
     Class I shares, respectively.

*    Net investment income allocated based on average shares method.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     shares nor the contingent deferred sales charge for Class B and C shares
     and does not reflect the deduction of taxes that a shareholder would pay on
     fund distributions or the redemption of fund shares.

*    Amounts are less than $0.005.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital contriubtion by
     Calamos Advisors. Excluding this item, total return would have been
     -11.30%, -11.73%, -11.87%, and -10.97% for Class A, Class B, Class C and
     Class I shares, respectively.

*    Net investment income allocated based on average shares method.

**   Amounts are less than $0.005 per share.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital contribution by
     Calamos Advisors. Excluding this item, total return would have been -6.83%,
     -9.34%, -7.46%, and -6.62% for Class A, Class B, Class C and Class I
     shares, respectively.

*    Amounts are less than $0.005 per share.

a)   Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital share
     contribution by Calamos Advisors. Excluding this item, the total return
     would have been 7.12%, 4.83%, and 5.63% for Class A, Class B and Class C
     shares respectively.

*    Amounts are less than $0.005 per share.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital contribution by
     Calamos Advisors. Excluding this item, total return would have been -3.36%,
     -6.16%, -4.01%, and -3.11% for Class A, Class B, Class C and Class I
     shares, respectively.

*    Amounts are less than $0.005 per share.

(a)  Total return measures net investment income and capital gain or loss from
     portfolio investments assuming reinvestment of dividends and capital gains
     distributions. Total return is not annualized for periods that are less
     than a full year, does not reflect the effect of sales charge for Class A
     nor the contingent deferred sales charge for Class B and C and does not
     reflect the deduction of taxes that a shareholder would pay on fund
     distributions or the redemption of fund shares.

(b)  In March 2001, the Fund's total return includes the capital contriubtion by
     Calamos Advisors. Excluding this item, total return would have been 8.57%,
     2.23%, 7.82% and 9.13%, for Class A, Class B, Class C and Class I shares,
     respectively.

(c)  Includes 0.6% for the six months ended September 30, 2005, 0.2%, 0.2%,
     0.3%, 0.1%, and 0.1% for the years 2005, 2004, 2003, 2002, and 2001,
     respectively, related to dividend expense on short positions.

*    Amounts are less than $0.005 per share.

102 SEMIANNUAL REPORT Financial Highlights



Trustee Approval of Management Agreement

The Board of Trustees of Calamos Investment Trust oversees the management of
each of the Funds, and, as required by law, determines annually whether to
continue the Trust's management agreement with Calamos Advisors under which
Calamos Advisors serves as the investment manager and administrator for the
Trust and each of the Fund's.

In connection with their most recent consideration of that agreement, the
Trustees received and reviewed information provided by Calamos Advisors in
response to detailed requests of the Independent Trustees and their independent
legal counsel and discussed with representatives of Calamos Advisors' the
operations of the Funds and the nature and quality of the advisory and other
services provided by Calamos Advisors to the Funds. The Trustees also received
and reviewed a memorandum from counsel to the Independent Trustees regarding the
Trustee's responsibilities in evaluating the management agreement. In the course
of their consideration of the agreement the Independent Trustees were advised by
their counsel, and in addition to meeting with management of Calamos Advisors
they met separately in executive session with their counsel.

At a meeting on June 30, 2005, based on their evaluation of the information
referred to above and other information, the Trustees determined that the
overall arrangements between the Funds and Calamos Advisors were fair and
reasonable in light of the nature and quality of the services provided by
Calamos Advisors and its affiliates, the fees charged for those services and
other matters that the Trustees considered relevant in the exercise of their
business judgment. At that meeting the Trustees, including all of the
Independent Trustees, unanimously approved continuation of the management
agreement through August 1, 2006, subject to earlier termination as provided in
the agreement.

In considering the continuation of the management agreement, the Trustees
reviewed and analyzed various factors that they determined were relevant,
including the factors described below, none of which by itself was considered
dispositive. However, the material factors and conclusions that formed the basis
for the Trustees' determination to approve the continuation of the management
agreement are discussed separately below.

NATURE, QUALITY AND EXTENT OF SERVICES

The Trustees reviewed the nature, extent and quality of Calamos Advisors'
services to the Funds, taking into account the investment objective and strategy
of each Fund and the knowledge of the Trustees gained from their regular
meetings with management on at least a quarterly basis. In addition, the
Trustees reviewed Calamos Advisors' resources and key personnel, especially
those who provide investment management services to the Funds. The Trustees also
considered other services provided to the Funds by Calamos Advisors, such as
managing the execution of portfolio transactions and the selection of
broker-dealers for those transactions, serving as the Funds' administrator,
monitoring adherence to the Funds' investment restrictions, producing
shareholder reports, providing support services for the Board and Board
committees, communicating with shareholders and overseeing the activities of
other service providers,


                  Trustee Approval of Management Agreement SEMIANNUAL REPORT 103



Trustee Approval of Management Agreement

including monitoring compliance with various Fund policies and procedures and
with applicable securities laws and regulations.

The Trustees concluded that the nature and extent of the services provided by
Calamos Advisors to each Fund were appropriate and consistent with the terms of
the management agreement, that the quality of those services had been consistent
with or superior to quality norms in the industry and that the Funds were likely
to benefit from the continued provision of those services. They also concluded
that Calamos Advisors had sufficient personnel, with the appropriate education
and experience, to serve the Funds effectively and had demonstrated its
continuing ability to attract and retain well qualified personnel.

PERFORMANCE OF THE FUNDS

The Trustees considered the performance results for each of the Funds over
various time periods. They reviewed information comparing each Fund's
performance with the performance of comparable funds and peer groups identified
by Lipper Inc., an independent provider of investment company data, and with the
Fund's benchmark. The Trustees noted that the long-term performance of each Fund
that had been in operation for more than two years compared favorably with its
relevant peer group and benchmark, with each of the Funds, except Value Fund,
placing in the top quintile in relation to its peer group for the five year
performance period, and with Value Fund, due to its inception date, placing in
the top quintile in relation to its peer group for the three year performance
period. Blue Chip Fund and International Growth Fund had commenced operations in
December 2003 and March 2005, respectively, and thus did not have long-term
performance records.

The Trustees concluded that, although past performance is not necessarily
indicative of future results, the Funds strong longer term performance was an
important factor in the Trustees' evaluation of the quality of services provided
by Calamos Advisors under the management agreement.

COSTS OF SERVICES AND PROFITS REALIZED BY CALAMOS ADVISORS

The Trustees examined information on fees and expenses of each Fund in
comparison to information for other comparable funds as provided by Lipper.
Also, the Trustees reviewed information on fees and expenses for additional
funds identified by Calamos Advisors. The Trustees noted that both the
contractual rates of management fees and the actual management fees after fee
waivers for most of the Funds were greater than the median management fees of
the respective Lipper peer groups. They also noted, however, that the overall
expense ratios of most of the Funds were below or not appreciably higher than
the median expense ratios of their respective peer groups.

The Trustees considered the methodology used by Calamos Advisors in determining
compensation payable to portfolio managers, the very competitive environment for
investment management talent, and the competitive market for mutual funds in
different distribution channels.


104 SEMIANNUAL REPORT Trustee Approval of Management Agreement



                                        Trustee Approval of Management Agreement

The Trustees reviewed information on the profitability of Calamos Advisors in
serving as each Fund's investment manager and of Calamos Advisors and its
affiliates in all of their relationships with each Fund, as well as an
explanation of the methodology utilized in allocating various expenses among the
Funds and other business units. The Trustees recognized that profitability
comparisons among fund managers are difficult because very little comparative
information is publicly available and profitability of any manager is affected
by numerous factors, including the organizational structure of the particular
manager, the types of funds and other accounts it manages, possible other lines
of business, the methodology for allocating expenses and the manager's capital
structure and cost of capital. However, based on the information available and
taking those factors into account, the Trustees concluded that the profitability
of Calamos Advisors regarding each Fund in relation to the services rendered was
not unreasonable.

The Trustees also reviewed Calamos Advisors' management fees for its
institutional separate accounts and for its subadvised funds (for which Calamos
Advisors provides portfolio management services only). Although in most
instances its sub-advisory, and in many instances its institutional separate
account, fees for various investment strategies are lower than the management
fees charged to the Funds with corresponding strategies, the Trustees noted that
Calamos Advisors performs significant additional services for the Funds that it
does not provide to those other clients, including administrative services,
oversight of the Funds' other service providers, trustee support, regulatory
compliance and numerous other services.

Finally, the Trustees considered the financial condition of Calamos Advisors,
which they found to be sound.

The Trustees concluded that the management fees and other compensation payable
by the Funds to Calamos Advisors and its affiliates were reasonable in relation
to the nature and quality of the services to be provided, taking into account
the fees charged by other advisors for managing comparable mutual funds with
similar strategies and the fees Calamos Advisors charges to other clients. The
Trustees also concluded that the Funds' estimated overall expense ratios, taking
into account quality of services provided by Calamos Advisors, the investment
performance of the Funds' and the expense limitations agreed to by Calamos
Advisors, were also reasonable.

ECONOMIES OF SCALE

The Trustees noted that the advisory fee schedule for each Fund except Blue Chip
Fund, Global Growth and Income Fund, High Yield Fund and Value Fund contains
breakpoints that reduce the fee rate on assets above specified levels. The
Trustees received and discussed information concerning whether Calamos Advisors
realizes economies of scale as a Fund's assets increase. The


                  Trustee Approval of Management Agreement SEMIANNUAL REPORT 105




Trustee Approval of Management Agreement

Trustees also considered Calamos Advisors' agreement to reimburse each of the
Funds for any ordinary operating expenses (excluding 12b-1 fees) for a fiscal
year above 1.50% of average net assets, subject, in the case of International
Growth Fund, to an upward or downward adjustment of such limitation for any
period equal to the performance fee adjustment applicable to that Fund for the
period. The Trustees concluded that the fee schedule for each Fund currently in
effect represents an appropriate sharing of economies of scale at current asset
levels, but concluded to continue their periodic consideration of economies of
scale.

OTHER BENEFITS TO CALAMOS ADVISORS

The Trustees also considered benefits that accrue to Calamos Advisors and its
affiliates from their relationship with the Funds. The Trustees concluded that,
other than the services to be provided by Calamos Advisors and its affiliates
pursuant to the management agreement and the fees payable by the Funds therefor,
the Funds and Calamos Advisors may potentially benefit from their relationship
with each other in other ways. Recognizing that an affiliate of Calamos Advisors
serves the Funds as distributor and receives compensation from the Funds for its
services to the Funds, the Trustees determined that such compensation was fair
and reasonable. The Trustees also considered Calamos Advisors' use of
commissions to be paid by the Funds on their portfolio brokerage transactions to
obtain proprietary research products and services benefiting the Funds and/or
other clients of Calamos Advisors. The Trustees concluded that Calamos Advisors'
use of "soft" commission dollars to obtain research products and services was
consistent with regulatory requirements and is beneficial to the Funds. They
concluded that, although Calamos Advisors derives or may derive additional
benefits through the use of soft dollars from the Funds portfolio transactions,
the Funds also benefit from the receipt of research products and services to be
acquired through commissions paid on the portfolio transactions of other clients
of Calamos Advisors. They also concluded that the Funds success could attract
other business to Calamos Advisors or its other funds and that Calamos Advisors'
success could enhance its ability to serve the Funds.

After full consideration of the above factors as well as other factors that were
instructive in analyzing the management arrangements, the Trustees, including
all of the Independent Trustees, concluded that the continuation of the
management agreement was in the best interest of each Fund and its shareholders.
