NOTES TO SCHEDULE OF INVESTMENTS

Note: Market values for securities denominated in foreign currencies are shown
in U.S. dollars. The principal amount for such securities is shown in the
respective foreign currency. The date shown on options represents the expiration
date of the option contract. The option contract may be exercised at any date on
or before the date shown.

*    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, 2006, the market value
     of 144A securities that could not be exchanged to the registered form is
     $99,991,470 or 10.3% of net assets.

@    Security, or portion of security, is on loan.

                  NOTES TO SCHEDULE OF INVESTMENTS (UNAUDITED)

NOTE 1

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 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 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
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. 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. 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.

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 again 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.

INVESTMENTS. The following information is presented on an income tax basis as of
January 31, 2006. 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,
2006 was as follows:

                                             ==============


NOTE 3

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.

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 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 3.59% to 4.61% for the period ended January 31, 2006. 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 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 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 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 and net unrealized losses are reported as a
liability on the Statement of Assets and Liabilities. The change in the value of

NOTE 6

SECURITIES LENDING. During the period ended January 31, 2006, 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 LLC
and the security lending agent will monitor the creditworthiness of the firms to
which the Fund lends securities. At January 31, 2006, the Fund had securities
valued at $182,404,060 that were on loan to broker-dealers and banks and
$186,803,172 in cash or cash equivalent collateral.
