(a) 144A securities are those that are exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities are generally issued to qualified institutional buyers ("QIBs"), such as the Fund. Any resale of these securities must generally be effected through a sale that is exempt from registration (e.g. a sale to another QIB), or the security must be registered for public sale. At July 31, 2004, the market value of 144A securities that cannot currently be exchanged to the registered form is $155,555,915 or 17.3% of net assets applicable to common shareholders of the Fund. (b) Non-income producing security. (c) Security, or portion of security, is on loan. At July 31, 2004, the Fund had securities valued at $337,982,161 on loan to brokers-dealers and banks. (d) Security is purchased with the cash collateral from securities loaned. FOREIGN CURRENCY ABBREVIATIONS EUR: EUROPEAN MONETARY UNIT GBP: GREAT BRITAIN POUND CALAMOS CONVERTIBLE AND HIGH INCOME FUND NOTE 1 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 approved by the Board of Trustees or a committee appointed 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, effected 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, 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 appointed by the Board of Trustees. INVESTMENT TRANSACTIONS. 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. NOTE 2 INVESTMENTS. The following information is presented on an income tax basis as of July 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 July 31, 2004 was as follows: Cost basis of investments $ 1,615,242,046 ================== Gross unrealized appreciation $ 63,457,031 Gross unrealized depreciation (23,971,583) ------------------ Net unrealized appreciation (depreciation) $ 39,485,448 ================== NOTE 3 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 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 July 31, 2004 were as follows: UNREALIZED TERMINATION NOTIONAL FIXED APPRECIATION COUNTERPARTY DATE AMOUNT (000) RATE FLOATING RATE (DEPRECIATION) ------------------------------------------------------------------------------------------------------- Citibank NA October 27, 2006 $ 100,000 2.80% 1 month LIBOR $ 706,079 Citibank NA October 27, 2007 200,000 3.27% 1 month LIBOR 861,696 Citibank NA October 27, 2008 100,000 3.65% 1 month LIBOR 1,727,998 -------------- $3,295,773 ============== ITEM 2.
