CALAMOS CONVERTIBLE OPPORTUNITIES AND INCOME FUND ANNUAL REPORT OCTOBER 31, 2002 [CALAMOS INVESTMENTS LOGO] Strategies for Serious Money(TM) PRESIDENT'S LETTER -------------------------------------------------------------------------------- President Photo -------------------------------------------------------------------------------- Dear Shareholder: In our debut report, I am pleased to have the chance to thank you for your decision to invest in the CALAMOS CONVERTIBLE OPPORTUNITIES AND INCOME FUND. For shareholders that are new to CALAMOS INVESTMENTS, we welcome you. To all our shareholders, we appreciate the confidence you have entrusted with us as we enter the closed-end fund arena. As with all of our products and services, we pledge to you our commitment to performance and exceptional client service. As we enter our first months as a fully invested, leveraged portfolio, we are confident that your Fund is well positioned to achieve that goal. CALAMOS has been researching and investing in higher-yielding, lower-quality portfolios of convertible and straight bonds for 25 years. Our quantitative research and qualitative analysis of companies, industries, and the economic environment enable us to identify both risks and opportunities for the Fund, constructing an appropriate mix of securities that aims to provide shareholders with significant total return, including high current income. ONE WAY TO USE THE FUND'S SIZABLE DIVIDEND TO YOUR ADVANTAGE IS THROUGH THE FUND'S DIVIDEND REINVESTMENT PLAN. I encourage you to consider participating in this program as a means to increase your number of shares in the Fund at significant cost savings. For example, when the Fund's market price is at a premium to its net asset value (NAV), dividends automatically reinvested through the plan purchase shares either at NAV or at 95% of the market price, whichever is greater. With more shares, investors increase their power of compounding, and the plan's cost savings and convenience make that prospect even more attractive. We have enclosed a brochure detailing the plan for your review. Again, thank you for entrusting your investment with the CALAMOS Convertible Opportunities and Income Fund. We pledge our continued commitment to serving you with Strategies for Serious Money. Sincerely, /S/ JOHN P. CALAMOS John P.

NOTES TO FINANCIAL STATEMENTS NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION. CALAMOS Convertible Opportunities and Income Fund (the "Fund"), was organized as a Delaware Business Trust on April 17, 2002 and is registered under the Investment Company Act of 1940 as a diversified, closed-end management investment company. The Fund commenced operations on June 28, 2002. The Fund's investment objective is to provide total return, through a combination of capital appreciation and current income. The Fund currently seeks to achieve its investment objective by investing substantially all of its assets in convertible securities and non-convertible income securities. PORTFOLIO VALUATION. Investments are stated at value. Securities for which quotations are readily available are valued at the last available sale prices on the exchange or market on which they are principally traded, or lacking any sales, at the mean of the most recently quoted bid and asked prices. Securities and other assets for which market quotations are not readily available or when the valuation methods mentioned above do not produce a value reflective of the fair value of a security, such security is valued at fair value determined in good faith by or under the direction of the Fund's board of trustees. Forward currency contracts are valued using forward currency exchange rates available from a quotation service. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME. Investment transactions are recorded on a trade date basis. 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 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 information becomes available. FOREIGN CURRENCY TRANSLATION. Values of investments denominated in foreign currencies are converted into U.S. dollars using the spot market rate of exchange at time of valuation. Purchases and sales of investments and dividend and interest income are translated into U.S. dollars using the spot market rate of exchanging prevailing on the respective dates of such transaction. Realized foreign exchange gain of $58,903 and unrealized foreign exchange loss of $4,312 incurred by the Fund are included as a component of net realized gain (loss) on investments and foreign currency transactions and change in net unrealized appreciation/depreciation on investments and foreign currency transactions, respectively. FEDERAL INCOME TAXES. No provision has been made for Federal income taxes since the Fund elected to be taxed as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986 and has made such distributions to shareholders as to be relieved of all Federal income taxes. DIVIDENDS. Dividends payable to shareholders are recorded by the Fund on the ex-dividend date. Income and capital gain dividends are determined in accordance with tax regulations, which may differ from generally accepted accounting principles in the United States. These differences are primarily due to differing treatment for foreign currency transactions. 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. (8) NOTES TO FINANCIAL STATEMENTS NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER PARTIES Pursuant to an investment advisory agreement with CALAMOS Asset Management, Inc. ("CAM"), the Fund pays a monthly fee at the annual rate of 0.80% of the Fund's 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 accrued liabilities (other than debt representing financial leverage). CAM has contractually agreed to waive its management fee in the amount of the 0.25% of the average weekly managed assets of the Fund for the first five full years of the Fund's operation through June 30, 2007 and a declining amount for an additional three years (0.18% of the average weekly managed in 2008, 0.11% of the average weekly managed in 2009, and 0.04% in 2010). Under the terms of the Administration Agreement, CAM pays the Administrator a monthly fee at an annual rate of 0.125% of the Fund's average weekly managed assets, subject to a monthly minimum fee of $12,500. Certain portfolio transactions for the Fund may be executed through CALAMOS FINANCIAL SERVICES, INC. ("CFS") as broker, consistent with the Fund's policy of obtaining best price and execution. During the period from June 28, 2002 though October 31, 2002, the Fund paid no brokerage commissions to CFS on purchases and sales of Fund securities. Certain officers and trustees of the Fund are also officers and directors of CFS and CAM. All officers and affiliated trustees serve without direct compensation from the Fund. The Fund offers a deferred compensation plan for its trustees who are not affiliated with CAM. Under the deferred compensation plan, a trustee may elect to defer all or a portion of the trustees' compensation. Amounts deferred are unfunded obligations of the Fund, whose value fluctuates with changes in the value of shares of one or more funds of Calamos Investment Trust (including reinvested distribution) designated by the trustee. NOTE 3 - INVESTMENTS Purchases and sales information for investments other than short-term obligations for the period June 28, 2002 to October 31, 2002 were as follows: Purchases $812,366,889 Proceeds from sales 10,092,750 The following information is presented on an income tax basis as of October 31, 2002. Differences between amounts for financial statement and Federal income tax purposes are primarily due to timing differences. The cost basis of investments for tax purposes at October 31, 2002 was as follows: Cost basis of investments $804,113,772 Gross unrealized appreciation 24,468,979 Gross unrealized depreciation (56,442,847) ------------ Net unrealized depreciation of investments (31,973,868) NOTE 4 - FORWARD FOREIGN CURRENCY CONTRACTS The Fund may engage in portfolio hedging with respect to change in currency exchange rates by entering into foreign currency contracts to purchase or sell currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Risks associated with such contracts include 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.
