We submit for your review this annual shareholder report for the 12-month period ended October 31, 2005. INVESTMENT OBJECTIVE As a reminder, the Fund seeks total return through a combination of capital appreciation and current income by investing in a diversified portfolio of equity, convertible and high-yield securities. Because convertible and high-yield securities tend to follow the movements of their companies' equity counterparts more than traditional fixed income securities, the Fund can be viewed as having substantial equity sensitivity, yet with a significant income component. It is thus well suited for investors who value consistent monthly income, but still desire exposure to the upside potential of the equity markets. FUND STRUCTURE The Fund is structured as a closed end fund listed on the NYSE. Closed end funds are complex in that while the actual fund value is calculated on a share basis and reflected in its Net Asset Value (NAV), the fund itself is the traded on the NYSE, where its market price is determined by buyers and sellers like many other securities. A closed-end fund's NAV and market price may be similar or different from each other, depending on the various factors that affect them. When there is a difference between the two, the fund is said to be trading at a premium (when its market price is higher than its NAV) or at a discount (when its market price is lower than its NAV). Since supply and demand determine the market price of the Fund it is important to understand the many factors that may influence this dynamic. In our opinion, some of the key factors that may affect the market price of a closed-end fund are the performance of the underlying portfolio as reflected in its NAV, its distribution rate, and general market conditions, including the trend of equity markets and comparative current yields. FUND DISCOUNT TO NAV AND PORTFOLIO PERFORMANCE The Fund has been trading at a discount to NAV, despite its outperformance relative to the equity markets. During the 12-month period, the Fund produced a total return of 8.95% at net asset value (NAV), comparing favorably with the total return of the equity market, represented by the S&P 500 Index's total return of 8.72%. The Fund's market price surpassed these annual returns with a total return gain of 10.35%, which effectively narrowed the discount that was present at the beginning of the period. Given the difficulties that the equity markets experienced during this period, the Fund's capacity to produce gains and distributions to shareholders is all the more distinguishing. As noted above, we believe that portfolio performance is a key consideration to market participants, and we will continue to strive to deliver such outperformance to our shareholders, and believe a record of success may positively affect the Fund's market recognition. LEVEL DISTRIBUTION POLICY The Fund's distribution policy is also a key consideration for our shareholders--and potential shareholders. In April 2005, we announced the Fund's adoption of a level rate distribution policy. Also at that time, the Fund announced a 16.7% increase in its monthly distribution rate compared with its prior rate. As of October 31, 2005, the Fund's monthly distribution of $0.0875 per share equated to an annualized yield of 7.66% based on the Fund's market price (and an annualized yield of 7.27% based on Strategic Total Return Fund President's Letter ANNUAL REPORT 1 President's Letter --------------------------- "In our opinion, a level rate policy combined with an attractive monthly distribution will benefit long-term investors in the Fund,..." --------------------------- --------------------------- "The portfolio is positioned to participate in the mid-growth phase of a healthy economy, in what we feel is a favorable market environment." --------------------------- --------------------------- "Looking ahead, we will strive to deliver market-like returns with significantly more income than a pure equity portfolio,..." --------------------------- CALAMOS STRATEGIC TOTAL RETURN FUND The views expressed in this report reflect those of Calamos Advisors LLC through December 16, 2005. The manager's views are subject to change at any time based on market and other conditions. This report is submitted for general information for the shareholders of the fund. the Fund's NAV). In our opinion, a level rate policy combined with an attractive monthly distribution will benefit long-term investors in the Fund, as we believe that closed-end fund investors consider consistent and significant distributions to be an important component of their long-term total-return goals. Since the Fund's focus on total return includes aiming for both income and capital appreciation, we expect the distribution to, at times, include realized capital gains. If any distribution exceeds the Fund's net investment company taxable income, the excess will generally be a tax-free return of capital, however we have not had to use this flexibility during this reporting period. During this period, the Fund delivered $0.9875 per share in distributions to shareholders, comprised of earned income as well as short-term and long-term capital gains. GENERAL MARKET CONDITIONS The impact of general market conditions to the Fund's portfolio performance is obviously an important factor. The portfolio is positioned to participate in rising equity markets. Unfortunately the vagaries of the markets are such that performance in the stock markets typically comes in spikes rather than consistent returns week to week or month to month. It's important to emphasize a key distinction of the Fund, namely its total return objective and focus on capital appreciation. The portfolio is positioned to participate in the mid- growth phase of a healthy economy, in what we feel is a favorable market environment. We believe that the Fed is near the end of the interest rate hikes and that the economy remains strong. Historically, this stage of the economic cycle has typically resulted in increasing earnings and cash flow, often resulting in higher equity values. For the Fund this presents the potential for capital gains, and, if realized ultimately should benefit our long-term investors. However, past performance of the market is no guarantee of future performance. Looking ahead, we will strive to deliver market-like returns with significantly more income than a pure equity portfolio, while providing timely and relevant communications to aid in market recognition. In the meantime, we believe it's worth reminding investors that buying discounted shares provides a yield higher than that calculated at NAV. A convenient means to accumulate more shares is via the Fund's dividend reinvestment plan. The plan offers current shareholders an efficient method of purchasing additional shares with a potential for cost savings. For example, if the Fund's shares are trading at a premium, dividends will be automatically reinvested through the plan at NAV or 95% of the market price, whichever is greater; if shares are trading at a discount, dividends will be reinvested by purchasing shares at the market price, below NAV. Please see the Fund's dividend reinvestment plan for more information. We appreciate your investment in the CALAMOS STRATEGIC TOTAL RETURN FUND, and look forward to serving your long-term investment plan in the coming months and years ahead.

See accompanying Notes to Financial Statements. Strategic Total Return Fund Statement of Changes in Net Assets ANNUAL REPORT 15 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 (the "1940 Act") 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. Under normal circumstances, the Fund will invest primarily in common and preferred stocks and income producing securities such as investment grade and below investment grade debt securities. PORTFOLIO VALUATION. In computing the Fund's net asset value, portfolio securities that are traded on a securities exchange in the United States, except for option securities, 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. 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 Strategic Total Return Fund 16 ANNUAL REPORT Notes to Financial Statements Notes to Financial Statements 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 selected by the advisor from rates quoted by any major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service. 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, 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 Fund's books on the transaction date and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign currency appreciation and depreciation 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 purchased call options is increased by premiums paid. The proceeds from securities sold through the exercise of purchased 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 written options. 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 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 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 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 fixed income securities. Financial records are not adjusted for temporary differences. Strategic Total Return Fund Notes to Financial Statements ANNUAL REPORT 17 Notes to Financial Statements Effective April 1, 2005, the Fund adopted a level rate monthly distribution to common shareholders, which may be modified by the Board of Trustees from time to time. Monthly distributions may include net investment income, net realized short-term capital gains and, if necessary, return of capital. In addition, distributions may include net realized long-term capital gains to the extent permitted by the 1940 Act. In order to make these monthly distributions, the Fund might have to sell a portion of its investment portfolio at a time when independent investment judgment might not dictate such action. Also, for purposes of maintaining level rate distributions the Fund may realize short-term capital gains on securities that, if sold at a later date, would have resulted in long-term capital gains. Maintenance of level rate distributions may increase transaction and tax costs associated with the Fund. INDEMNIFICATIONS. Under the Fund's organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts that provide general indemnifications to other parties. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. NOTE 2 - INVESTMENT ADVISOR 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 Fund's total assets (including any assets attributable to any leverage that may be outstanding) minus 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 total average daily net assets of Calamos Investment Trust and Calamos Advisors Trust and the average weekly managed assets of Calamos Convertible and High Income Fund, Calamos Convertible Opportunities and Income Fund, Calamos Strategic Total Return Fund and Calamos Global Total Return 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 liabilities and monitoring trustee deferred compensation plan accruals and valuations. The Fund will pay its pro rata share of the financial accounting service fee payable to Calamos Advisors based on the Fund's relative portion of combined assets. Effective August 1, 2005 the Fund began reimbursing the advisor for a portion of the compensation paid to the Chief Compliance Officer of the Trust. This compensation is reported as part of "Other" expenses on the Statement of Operations. Certain officers and Trustees of the Fund are also officers and directors of Calamos Financial Services LLC ("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" (as defined in the 1940 Act) of CFS or 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 participating trustee. The value of a participating 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 Strategic Total Return Fund 18 ANNUAL REPORT Notes to Financial Statements Notes to Financial Statements 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 $18,793 are included in "Other assets" on the Statement of Assets and Liabilities at October 31, 2005. The Fund's obligation to make payments under the Plan is a general obligation of the Fund and is included in "Payable for deferred compensation to Trustees" on the Statement of Assets and Liabilities at October 31, 2005. NOTE 3 - INVESTMENTS Purchases and sales of investments, other than short-term obligations, for the year ended October 31, 2005 were as follows: Purchases $ 2,356,158,553 Proceeds from sales 2,408,437,660 The following information is presented on an income tax basis as of October 31, 2005. Differences between amounts for financial statements and Federal income tax purposes are primarily due to timing differences. The cost basis of investments for federal income tax purposes at October 31, 2005 was as follows: Cost basis of investments $ 3,826,167,866 --------------- Gross unrealized appreciation 200,554,378 Gross unrealized depreciation (210,394,028) --------------- Net unrealized appreciation (depreciation) $ (9,839,650) --------------- NOTE 4 - INCOME TAXES For the year ended October 31, 2005, the Fund recorded the following permanent reclassifications to reflect tax character.

Strategic Total Return Fund Notes to Financial Statements ANNUAL REPORT 19 Notes to Financial Statements NOTE 5 - COMMON STOCK There are unlimited common shares of beneficial interest authorized and 154,514,000 shares outstanding at October 31, 2005. Calamos Advisors owned 15,450 of the outstanding shares at October 31, 2005. Transactions in common shares were as follows: FOR THE PERIOD ENDED FOR THE PERIOD ENDED OCTOBER 31, 2005 OCTOBER 31, 2004* -------------------- -------------------- Beginning shares 154,514,000 -- Shares sold -- 154,514,000 Shares issued through reinvestment of distributions -- -- ----------- ----------- Ending shares 154,514,000 154,514,000 =========== =========== -------- * 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, 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. There were no open forward foreign currency contracts at October 31, 2005. NOTE 7 - SYNTHETIC CONVERTIBLE SECURITIES The Fund 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 Fund 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 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. Strategic Total Return Fund 20 ANNUAL REPORT Notes to Financial Statements Notes to Financial Statements NOTE 8 - OPTIONS TRANSACTIONS The Fund may engage in options transactions and in doing so achieve similar objectives to what it would achieve through the sale or purchase of individual securities. Transactions in options written during the year ended October 31, 2005 were as follows: NUMBER OF PREMIUMS CONTRACTS RECEIVED --------- ---------- Options outstanding at October 31, 2004 6,900 $1,127,898 Options written 107,461 8,037,670 Options closed (72,360) (6,296,540) Options expired (34,790) (1,615,436) Options exercised (5,111) (865,915) --------- ---------- Options outstanding at October 31, 2005 2,100 $ 387,677 ========= ========== NOTE 9 - PREFERRED SHARES 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 1.81% to 3.96% for the year ended October 31, 2005. Under the 1940 Act, the Fund may not declare dividends or make other distributions on shares of common stock or purchases 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 Fund's option, 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 in the value of the swap or cap, which may result in a decline in the Fund's net asset value. 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. Net unrealized gains are reported as an asset or net unrealized losses are reported as a liability on the Strategic Total Return Fund Notes to Financial Statements ANNUAL REPORT 21 Notes to Financial Statements Statement of Assets and Liabilities. The change in the value of the swaps, including periodic amounts of interest to be paid or received on swaps is reported as unrealized gains or losses in the Statement of Operations. A realized gain or loss is recorded upon payment or termination of swap agreements. Details of the swap agreements outstanding as October 31, 2005 were as follows: UNREALIZED TERMINATION NOTIONAL FIXED RATE FLOATING RATE APPRECIATION COUNTERPARTY DATE AMOUNT (000) (FUND PAYS) (FUND RECEIVES) (DEPRECIATION) ------------ ---------------- ------------- ----------- --------------- --------------- Citibank NA June 4, 2006 $ 150,000 3.04% 1month LIBOR $ 1,357,148 Citibank NA February 4, 2007 150,000 3.68% 1month LIBOR 1,804,322 Citibank NA June 4, 2007 150,000 3.61% 1month LIBOR 2,484,689 Citibank NA February 4, 2008 150,000 3.88% 1month LIBOR 2,731,238 Citibank NA June 4, 2009 200,000 4.34% 1month LIBOR 2,812,447 Citibank NA February 4, 2010 200,000 4.14% 1month LIBOR 5,103,474 --------------- $ 16,293,318 =============== NOTE 11 - SECURITIES LENDING During the year ended October 31, 2005 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 continues to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receives 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 has 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 does 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) the expenses of enforcing its rights. In an effort to reduce these risks, Calamos Advisors and the security lending agent will monitor the creditworthiness of the firms to which the Fund lends securities. At October 31, 2005, the Fund had securities valued at $536,098,533 that were on loan to broker-dealers and banks and $547,802,375 in cash or cash equivalent collateral.

(a) Net of sales load of $0.675 on initial shares issued and beginning net asset value of $14.325. (b) Total investment return is calculated assuming a purchase of common stock on the opening of the first day and a sale on the closing of the last day of the period reported. Dividends and distributions are assumed, for purposes of this calculation, to be reinvested at prices obtained under the Fund's dividend reinvestment plan. Total return is not annualized for periods less than one year. Brokerage commissions are not reflected. NAV per share is determined by dividing the value of the Fund's portfolio securities, cash and other assets, less all liabilities, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the Fund at a given time. Common share market price is influenced by a range of factors, including supply and demand and market conditions. (c) Annualized for periods less than one year. (d) Does not reflect the effect of dividend payments to preferred shareholders. (e) Calculated by subtracting the Fund's total liabilities (not including preferred shares) from the Fund's total assets and dividing this by the number of Preferred Shares outstanding. See accompanying Notes to Financial Statements Strategic Total Return Fund Financial Highlights ANNUAL REPORT 23 Report of Independent Registered 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, 2005, the related statement of operations for the year then ended, and the statements of changes in net assets and the financial highlights for the year then ended and 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. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with the Fund's custodian and brokers. 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, 2005, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for the year then ended and 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. /s/ [DELOITTE & TOUCHE LLP] Chicago Illinois December 16, 2005 Strategic Total Return Fund 24 ANNUAL REPORT Report of Independent Registered Public Accounting Firm Tax Information (unaudited) We are providing this information as required by the Internal Revenue Code (Code). The amounts shown may differ from those elsewhere in this report due to differences between tax and financial reporting requirements. In January 2006, shareholders will receive Form 1099-DIV which will include their share of qualified dividends and capital gains distributed during the calendar year 2005. Shareholders are advised to check with their tax advisors for information on the treatment of these amounts on their individual income tax returns. Under Section 854(b)(2) of the Code, the Fund hereby designates $57,326,514, or the maximum amount allowable under the Code, as qualified dividends for the fiscal year ended October 31, 2005. Under Section 854(b)(2) of the Code, the Fund hereby designates 27.26% of the ordinary income dividends as income qualifying for the corporate dividends received deduction for the fiscal year ended October 31, 2005. Strategic Total Return Fund Tax Information ANNUAL REPORT 25 Trustee Approval of Management Agreement (unaudited) The Board of Trustees of the Fund oversees the Fund's management and, as required by law, determines annually whether to continue the Fund's management agreement with Calamos Advisors under which Calamos Advisors serves as the investment manager for the Fund. 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 Fund's operations and the nature and quality of the advisory and other services provided by Calamos Advisors to the Fund. 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 Fund 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 Fund, taking into account the investment objective and strategy of the 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 Fund. The Trustees also considered other services provided to the Fund by Calamos Advisors, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, monitoring adherence to the Fund's 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, 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 the 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 Fund was 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 Fund effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. PERFORMANCE The Trustees considered the Fund's performance results over various time periods. They reviewed information comparing the 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 Fund had less than three years of performance data, and thus did not have a long-term performance record. The Trustees concluded that given the short performance history, performance was not the most important factor in the Trustees' evaluation of the quality of services provided by Calamos Advisors under the management agreement. Strategic Total Return Fund 26 ANNUAL REPORT Trustee Approval of Management Agreement Trustee Approval of Management Agreement (unaudited) COSTS OF SERVICES AND PROFITS REALIZED BY CALAMOS ADVISORS The Trustees examined information on fees and expenses of the 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 the contractual rate of management fees, the actual management fees after fee waivers and the overall expense ratios for the Fund were greater than the median management fees of its Lipper peer group. 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. The Trustees reviewed information on the profitability of Calamos Advisors in serving as the Fund's investment manager and of Calamos Advisors and its affiliates in all of their relationships with the Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Fund 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 the 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 Fund, the Trustees noted that Calamos Advisors performs significant additional services for the Fund that it does not provide to those other clients, including oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the Trustees considered Calamos Advisors' financial condition, which they found to be sound. The Trustees concluded that the management fee and other compensation payable by the Fund 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 Fund's estimated overall expense ratios, taking into account quality of services provided by Calamos Advisors, the Fund's investment performance of the Funds' and the expense limitations agreed to by Calamos Advisors, were also reasonable. ECONOMIES OF SCALE In reviewing the Fund's fees and expenses, the Trustees examined the potential benefits of economies of scale, and whether any economies of scale should be reflected in the Fund's fee structure. They noted that the Fund has had a relatively stable asset base since commencement of operations and that there do not appear to have been significant economies of scale realized since that time. Strategic Total Return Fund Trustee Approval of Management Agreement ANNUAL REPORT 27 Trustee Approval of Management Agreement (unaudited) OTHER BENEFITS TO CALAMOS ADVISORS The Trustees also considered benefits that accrue to Calamos Advisors and its affiliates from their relationship with the Fund. 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 Fund therefor, the Fund and Calamos Advisors may potentially benefit from their relationship with each other in other ways. The Trustees also considered Calamos Advisors' use of commissions to be paid by the Fund on its portfolio brokerage transactions to obtain proprietary research products and services benefiting the Fund 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 Fund. They concluded that, although Calamos Advisors derives or may derive additional benefits through the use of soft dollars from the Fund's portfolio transactions, the Fund also benefits 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 Fund's success could attract other business to Calamos Advisors or its other funds and that Calamos Advisors' success could enhance its ability to serve the Fund. 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 the Fund and its shareholders.
