NOTES TO SCHEDULE OF INVESTMENTS

Note: Market Value for securities denominated in foreign currencies are shown in
U.S. dollars.

(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 January 31,
        2005 the market value of 144A securities that could not be exchanged 
        to the registered form were $161,048,117 or 16.6 % of net assets
        applicable to common shareholders of the Fund.
(b)     Security, or portion of security, is on loan.
(c)     Non-Income producing security.

                  NOTES TO SCHEDULE OF INVESTMENTS (UNAUDITED)

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 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 Fund 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 Fund's
pricing time but after the closed 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
official closing 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 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. 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.

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.

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 a Fund writes an option, an amount equal to the premium received by a 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 a 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 a Fund has realized a gain or loss. If a put
option is exercised, the premium reduces the cost basis of the securities
purchased by a Fund. A Fund as writer of an option bears the market risk of an
unfavorable change in the price of the security underlying the written option.


NOTE 2
INVESTMENTS. The following information is presented on an income tax basis as of
January 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 January 31, 2005 was as
follows:

                  NOTES TO SCHEDULE OF INVESTMENTS (UNAUDITED)

NOTE 3
SYNTHETIC CONVERTIBLE SECURITIES. The Fund may establish a "synthetic"
convertible instrument by combining separate securities that possess 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.


NOTE 4
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 17,200 shares of Preferred
Shares outstanding consist of six series, 3,000 shares of M, 3,000 shares of TU,
3,000 shares of W, 3,000 shares of TH, 3,000 shares of F and 2,200 shares of A.
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 1.65% to 2.71% for the period ended January 31, 2005. 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 5
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 January 31, 2005 were
as follows:

NOTE 6
SECURITIES LENDING. During the period ended January 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) expenses of
enforcing its rights. In an effort to reduce these risks, Calamos Advisors, LLC
and the security lending agent will monitor the creditworthiness of the firms to
which each Fund lends securities. At January 31, 2005 the Fund had securities
valued at $238,796,636 on loan to broker-dealers and banks and had $244,818,504
in cash collateral.
