Reports to Stockholders CALAMOS STRATEGIC TOTAL RETURN FUND ANNUAL REPORT OCTOBER 31, 2004 [CALAMOS INVESTMENTS LOGO] Strategies for Serious Money(R) PRESIDENT'S LETTER -------------------------------------------------------------------------------- PRESIDENT PHOTO -------------------------------------------------------------------------------- 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 John P. Calamos, Sr. Chairman, Chief Executive Officer and Chief Investment Officer Strategies for Serious Money (R) 1 STRATEGIC TOTAL RETURN FUND PERFORMANCE NAV/MARKET PRICE INCEPTION THROUGH OCTOBER 31, 2004 LINE GRAPH 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(+) ------------------------------- 1 SINCE YEAR INCEPTION ------------------------------- Common Shares -- Inception 3/26/04 On Market Price N/A -8.59% On NAV N/A 2.10% ----------------------------------------------------------------------------------------------- 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. 2 Strategies for Serious Money (R) STRATEGIC TOTAL RETURN FUND PORTFOLIO FUND SECTOR ALLOCATION [LINE GRAPH] Financials 19.0 Consumer Discretionary 17.0 Health Care 12.3 Industrials 11.3 Energy 9.0 Information Technology 8.2 Telecommunication Services 7.8 Consumer Staples 6.9 Materials 6.8 Utilities 1.7 Sector allocations are based on total investments (excluding security lending collateral and short-term investments) and may vary over time.

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. 16 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. NOTE 3 - INVESTMENTS Purchases and sales of investments other than short-term obligations for the period ended October 31, 2004 were as follows. Purchases $3,521,965,126 Proceeds from sales 289,499,881 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 investments for Federal income tax purposes at October 31, 2004 was as follows: Cost basis of investments $3,637,224,291 -------------- Gross unrealized appreciation 151,029,186 Gross unrealized depreciation (140,074,218) -------------- Net unrealized appreciation (depreciation) $ 10,954,968 ============== 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. Paid-in capital $ (14,000) Undistributed net investment income (loss) (6,857,124) Accumulated net realized gain (loss) on investments, written options, foreign currency transactions and interest rate swaps 6,871,124 17 NOTES TO FINANCIAL STATEMENTS Distributions during the fiscal period ended October 31, 2004 were characterized for income tax purposes as follows: 2004* ------------------------------------------------------------------------------ DISTRIBUTIONS PAID FROM: Ordinary income $ 62,365,389 Long-term capital gain -- * The Fund commenced operations on March 26, 2004. As of October 31, 2004, the components of net assets on a tax basis were as follows: Undistributed ordinary income $ 11,360,755 Undistributed capital gains -- -------------- Total undistributed earnings 11,360,755 Accumulated capital and other losses (10,297,008) Unrealized gains/(losses) 1,560,175 -------------- Total accumulated earnings/(losses) 2,623,922 Other (4,128,566) Paid-in capital 2,200,733,859 ============== $2,199,229,215 ============== The Fund intends to retain realized gains to the extent of available capital loss carryforwards for federal income tax purposes. As of October 31, 2004, the Fund had capital loss carryforwards of $10,297,008 which, if not used, will expire in 2012. NOTE 5 - COMMON STOCK There are unlimited common shares of beneficial interest authorized and 154,514,000 shares outstanding at October 31, 2004. Calamos Advisors LLC owned 14,390 of the outstanding shares. Transactions in common shares were as follows: PERIOD ENDED OCTOBER 31, 2004* --------------------------------------------------------------------------------- Beginning shares -- Shares sold 154,514,000 Shares issued through reinvestment of distributions -- ----------- Ending shares 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 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 CONTRACTS RECEIVED --------------------------------------------------------------------------------------- Options written 8,900 $1,313,894 Options closed (2,000) (185,996) ------ ---------- Options outstanding at October 31, 2004 6,900 $1,127,898 ====== ========== 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 TERMINATION NOTIONAL FLOATING APPRECIATION COUNTERPARTY DATE AMOUNT (000) FIXED RATE RATE (DEPRECIATION) --------------------------------------------------------------------------------------------------------------------------------- Citibank NA June 4, 2006 $150,000 3.04% 1 month LIBOR $ (893,779) Citibank NA June 4, 2007 150,000 3.61% 1 month LIBOR (2,353,600) Citibank NA June 4, 2008 200,000 4.34% 1 month LIBOR (7,202,649) ------------ $(10,450,028) ============ ======== ===== ============= ============ 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. 20 FINANCIAL HIGHLIGHTS SELECTED DATA FOR A SHARE OUTSTANDING THROUGHOUT THE PERIOD WAS AS FOLLOWS: March 26, 2004* through October 31, 2004 -------------------------------------------------------------------------------- Net asset value, beginning of period $ 14.32(a) ---------- Income from investment operations: Net investment income (loss) 0.51 Net realized and unrealized gain (loss) from investments, options, foreign currency and interest rate swaps (0.09) Dividends to preferred shareholders from: Net investment income (common share equivalent basis) (0.06) ---------- Total from investment operations 0.36 -------------------------------------------------------------------------------- Less dividends to common shareholders from: Net investment income (0.37) Capital charge resulting from issuance of common and preferred shares (0.08) ---------- -------------------------------------------------------------------------------- Net asset value, end of period $ 14.23 ========== Market value, end of period $ 13.34 -------------------------------------------------------------------------------- Total investment return based on(b): Net asset value 2.10% Market value (8.59)% -------------------------------------------------------------------------------- Ratios and Supplemental Data: Net assets applicable common shareholders, end of period (000's omitted) $2,199,229 Preferred shares, at redemption value ($25,000 per share liquidation preference) (000's omitted) $1,080,000 Ratios to average net assets applicable to common shareholders: Net expenses(c)(e) 1.61% Net investment income (loss)(c)(e) 6.27% Preferred share dividends(c) 0.67% Net investment income (loss), net of preferred share dividends(c) 5.59% Portfolio turnover rate 11% Average commission rate paid $ .0197 Asset coverage per preferred share, at end of period(d) $ 75,916 -------------------------------------------------------------------------------- * Commencement of operations.

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. /s/ Deloitte & Touche LLP Chicago, Illinois December 21, 2004 22 TAX INFORMATION (UNAUDITED) TAX INFORMATION.
