Dear Shareholder:
       We are proud to bring you the first annual report for the CALAMOS
Strategic Total Return Fund (CSQ) covering the fiscal year ended October 31,
2004. Please note that CSQ's inception date was March 26, 2004, meaning this
report does not cover an entire 12 month period.
       For those of you who are new to CSQ or to Calamos Investments, we welcome
you as an investor. For those of you who are already familiar with our
dedication to risk management and long-term performance, I thank you for your
confidence in our investment process. In CSQ, as in all of our funds, we strive
to maintain an appropriate balance between risk and reward that seeks to provide
you with outstanding long-term performance.
       The investment objective of CSQ is to seek total return, pursued by
investing in a combination of equity, convertible, and high-yield securities.
Based on its NAV performance and dividends, we believe that the Fund's objective
has been achieved, delivering a total return that is in line with the overall
equity market (as represented by the S&P 500), with a strategy that is designed
to offer a total return that is more balanced between capital appreciation and
income than that of a pure-equity fund. Despite positive NAV performance, the
Fund's market price has traded at a discount to NAV. We look forward to
expanding our communication efforts in 2005 to help investors understand the
Fund's objective. At fiscal year end, the Fund's managed assets were
approximately 48% common stock equity securities, with the remainder in
convertible securities and high-yield bonds. To help offset some of the effects
of rising short-term interest rates on the Fund's yield, the Fund has continued
to maintain interest-rate swap positions in connection with approximately half
of its leveraged assets.
       As part of its focus on total return, the Fund has paid a consistent
dividend throughout its fiscal year. Remember that you can use these
distributions to your advantage by reinvesting them through the Fund's dividend
reinvestment plan and accumulate additional shares of the fund. Through this
plan, when the Fund's market price is at a discount to NAV, your distributions
are used to purchase shares at this lower price, and even when the Fund is at
premium to its NAV, your dividends automatically purchase shares at NAV or 95%
of the market price, whichever is greater.
       As CALAMOS Investments continues to expand its investment offerings and
asset management capabilities, we remain committed to helping you achieve your
long-term financial goals. Thank you for choosing the CALAMOS Strategic Total
Return Fund.
 
                                                    Sincerely,
 
                                                    /s/ John P. Calamos

      COMMENTARY
 
      Despite positive NAV performance since inception, as of fiscal year-end,
      Calamos Strategic Total Return Fund was trading at a discount to its NAV.
      We continue to manage the portfolio consistent with the principal
      investment strategies established in connection with the Fund's initial
      public offering and with the terms of the original offering. In 2005, we
      will strive to expand our communications efforts regarding the Fund's
      characteristics and long-term goals.
 
      We seek to provide:
 
         - Total return, achieved through a combination of capital appreciation
           and current income
 
         - A dynamic allocation among common stock and other income-producing
           securities, with at least 50% of managed assets in equities or
           securities convertible into equities
 
         - A competitive and consistent distribution rate
 


                                                                    Average Annual Total Return(+)

   PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. You can purchase or sell
   common shares daily. Like any other stock, market price will fluctuate with
   the market. Upon sale, your shares may have a market price that is above or
   below net asset value and may be worth more or less than your original
   investment. Due to ongoing market volatility, performance is subject to
   substantial short-term fluctuations.
 
   +  Total return measures net investment income and capital gain or loss from
      portfolio investments, assuming reinvestment of income and capital gains
      distributions.

 14             See accompanying Notes to Financial Statements.

 
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION.  CALAMOS Strategic Total Return Fund (the "Fund") was organized as
a Delaware statutory trust on December 31, 2003 and is registered under the
Investment Company Act of 1940 as a diversified, closed-end management
investment company. The Fund commenced operations on March 26, 2004.
 
The Fund's investment objective is to provide total return through a combination
of capital appreciation and current income.
 
PORTFOLIO VALUATION.  In computing the net asset value of the Fund, portfolio
securities, including options, that are traded on a national securities exchange
are valued at the last reported sales price. Securities quoted on the NASDAQ
National Market System are 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. Securities traded in the over-the-counter
market and listed securities for which no sales were reported are valued at the
mean of the most recently quoted bid and asked prices. 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 valued at a fair value following procedures or guidelines approved
by the Board of Trustees or a committee approved by the Board of Trustees. The
Fund may also use fair value pricing, if the value of a security it holds is, in
the opinion of the valuation committee or pursuant to Board of Trustees'
guidelines, may be significantly affected by events occurring 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 or a committee thereof, 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
Fund's net asset value may differ from quoted or published prices.
 
Securities that are principally traded in a foreign market are valued 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 valued at a
fair value following procedures approved by the Board of Trustees or a committee
approved by the Board of Trustees.
 
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.  Values of investments and other assets and
liabilities denominated in foreign currencies are translated into U.S. dollars
using the spot market rate of exchange at the date of valuation. Purchases and
sales of investments and dividend and interest income are translated into U.S.
dollars using the spot market rate of exchange prevailing on the respective
dates of such transaction.
 
                                                                              15

                         NOTES TO FINANCIAL STATEMENTS
 
The Fund does 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, 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
Fund's 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 Fund may purchase
or write (sell) put and call options. One of the risks associated with
purchasing an option among others, is that the Fund pays a premium whether or
not the option is exercised. Additionally, the Fund bears 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 the Fund writes an option, an amount equal to the premium received by the
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 the 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 call option is
exercised, the premium is added to the proceeds from the sale of the underlying
security or currency in determining whether the Fund has realized a gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
securities purchased by the Fund. The Fund, as writer of an option, bears the
market risk of an unfavorable change in the price of the security underlying the
written option.
 
USE OF ESTIMATES.  The preparation of financial statements in conformity with
accounting principles generally accepted in the United States 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.
 
NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER
PARTIES
 
Pursuant to an investment advisory agreement with Calamos Advisors LLC ("Calamos
Advisors"), the Fund pays an annual fee, payable monthly, equal to 1.00% based
on the average weekly managed assets. "Managed Assets" means the total assets of
the Fund (including any assets attributable to any leverage that may be
outstanding) minus the sum of total liabilities (other than debt representing
financial leverage).
 
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
managed assets of Calamos Investment Trust, Calamos Advisors Trust, Calamos
Convertible and High Income Fund and Calamos Strategic Total Return Fund).
Effective November 1, 2004 the managed assets of Calamos Convertible
Opportunities and Income Fund will be included in combined assets. 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 will pay their pro rata share of the financial accounting
service fee payable to Calamos Advisors based on relative assets of each Fund.

                         NOTES TO FINANCIAL STATEMENTS
 
Certain officers and trustees of the Fund are also officers and directors of CFS
and Calamos Advisors. All officers and affiliated trustees serve without direct
compensation from the Fund. The Fund 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
Fund. 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 trustee. The value of a trustee's deferred 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 $4,762 are included in "Other Assets" on the Statement of Assets and
Liabilities at October 31, 2004. The Fund's obligation to make payments under
the Plan is a general obligation of the Fund.

The following information is presented on an income tax basis as of October 31,
2004. Differences between amounts for financial statements and Federal income
tax purposes are primarily due to timing differences. The cost basis of

NOTE 4 - INCOME TAXES
No provision has been made for income taxes because the Fund'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.
 
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 accounting principles generally accepted in
the United States of America. 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. Financial records are not adjusted for temporary differences.
 
For the year ended October 31, 2004, the Fund recorded the following permanent
reclassifications to reflect tax character. Results of operations and net assets
were not affected by these reclassifications.

* The Fund commenced operations on March 26, 2004.
 
NOTE 6 - FORWARD FOREIGN CURRENCY CONTRACTS
 
The Fund may engage in portfolio hedging with respect to changes in currency
exchange rates by entering into forward 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 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 (loss), 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. There were no
open forward foreign currency contracts at October 31, 2004.
 
NOTE 7 - SYNTHETIC CONVERTIBLE SECURITIES
 
The Fund may create a "synthetic" convertible security by combining separate
securities that possess the two principal characteristics of a true 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
 18

                         NOTES TO FINANCIAL STATEMENTS
 
investing in warrants or options to buy common stock at a certain exercise
price, or options on a stock index. In creating a synthetic security, the Fund
may also 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 Fund 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 - OPTIONS TRANSACTIONS
 
The Fund may engage in options transactions and in doing so achieve the similar
objectives to what they would achieve through the sale or purchase of individual
securities. Transactions in options written during the period ended October 31,
2004 were as follows:
 


                                                                NUMBER OF     PREMIUMS

NOTE 9 - PREFERRED SHARES
 
There are unlimited shares of Auction Rate Cumulative Preferred Shares
("Preferred Shares") authorized. The Preferred Shares have rights as determined
by the Board of Trustees. The 43,200 shares of Preferred Shares outstanding
consist of seven series, 7,040 shares of M, 7,040 shares of TU, 7,040 shares of
W, 7,040 shares of TH, 7,040 shares of F, 4,000 shares of A, and 4,000 shares of
B. The Preferred Shares have a liquidation value of $25,000 per share plus any
accumulated but unpaid dividends whether or not declared.
 
Dividends on the Preferred Shares are cumulative at a rate typically reset every
seven or twenty-eight days based on the results of an auction. Dividend rates
ranged from 1.08% to 2.01% for the period ended October 31, 2004. Under the
Investment Company Act of 1940, the Fund may not declare dividends or make other
distributions on shares of common stock or purchase any such shares if, at the
time of the declaration, distribution or purchase, asset coverage with respect
to the outstanding Preferred Shares would be less than 200%.
 
The Preferred Shares are redeemable at the option of the Fund, in whole or in
part, on any dividend payment date at $25,000 per share plus any accumulated but
unpaid dividends. The Preferred Shares are also subject to mandatory redemption
at $25,000 per share plus any accumulated but unpaid dividends, whether or not
declared, if certain requirements relating to the composition of the assets and
liabilities of the Fund as set forth in the Statement of Preferences are not
satisfied.
 
The holders of Preferred Shares have voting rights equal to the holders of
common stock (one vote per share) and will vote together with holders of shares
of common stock as a single class except on matters affecting only the holders
of Preferred Shares or the holders of common shares.
 
NOTE 10 - INTEREST RATE TRANSACTIONS
 
The Fund may enter into interest rate swap or cap transactions to attempt to
protect itself from increasing dividend or interest expense on its leverage
resulting from increasing short-term interest rates. A decline in interest rates
may result in a decline
 
                                                                              19

                         NOTES TO FINANCIAL STATEMENTS
 
in the value of the swap or cap, which may result in a decline in the net asset
value of the Fund. In addition, if the counterparty to an interest rate swap or
cap defaults, the Fund would not be able to use the anticipated receipts under
the swap or cap to offset the dividend or interest payments on the Fund's
leverage. At the time an interest rate swap or cap reaches its scheduled
termination, there is a risk that the Fund would not be able to obtain a
replacement transaction or that the terms of the replacement would not be as
favorable as on the expiring transaction. In addition, if the Fund is required
to terminate any swap or cap early due to the Fund failing to maintain a
required 200% asset coverage of the liquidation value of the outstanding
Preferred Shares or the Fund loses its credit rating on its Preferred Shares,
then the Fund could be required to make a termination payment, in addition to
redeeming all or some of the Preferred Shares. Details of the swap agreements
outstanding as of October 31, 2004 were as follows:
 


                                                                                                                     UNREALIZED

NOTE 11 - SECURITIES LENDING
 
During the period ended October 31, 2004, the Fund lent 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
Fund. The Fund would continue to receive the equivalent of the interest or
dividends paid by the issuer on the securities loaned and would also receive an
additional return that may be in the form of a fixed fee or a percentage of the
collateral. The Fund may pay reasonable fees to persons unaffiliated with the
Fund for services in arranging these loans. The Fund would 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 Fund would 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 Fund 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 Fund seeks to enforce its rights
thereto, (b) possible subnormal levels of income and lack of access to income
during this period, and (c) expenses of enforcing its rights. In an effort to
reduce these risks, the investment manager and security lending agent will
monitor the creditworthiness of the firms to which the Fund lends securities. At
October 31, 2004, the Fund had securities valued at $363,839,184 that were on
loan to broker-dealers and banks and $371,513,731 in cash equivalent collateral.

                             PUBLIC ACCOUNTING FIRM
 
To the Board of Trustees and Shareholders of
CALAMOS Strategic Total Return Fund
 
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of CALAMOS Strategic Total Return Fund (the "Fund")
as of October 31, 2004, and the related statement of operations, statement of
changes in net assets and the financial highlights for the period from March 26,
2004 (commencement of operations) through October 31, 2004. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004, by correspondence with the Fund's
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of October 31, 2004, and the results of its operations, the changes in
its net assets, and the financial highlights for the period from March 26, 2004
(commencement of operations) through October 31, 2004, in conformity with
accounting principles generally accepted in the United States of America.

    The audit committee shall pre-approve all non-audit services to be provided
by the principal accountants to the registrant, including the fees and other

pre-approval of non-audit services is waived if (i) the services were not
recognized by management at the time of the engagement as non-audit services,

are less than 5% of the total fees paid by the registrant to its principal

committee by management and the audit committee approves them prior to the
completion of the audit.

    The audit committee shall pre-approve all non-audit services to be provided
by the principal accountants to the investment adviser or any entity

is not required if (i) the services were not recognized by management at the
time of the engagement as non-audit services, (ii) the aggregate fees for all
non-audit services provided to the adviser and all entities controlling,
controlled by or under common control with the adviser are less than 5% of the
