In accordance with the above, the Fund's Prospectus, SAI and Prospectus Supplement are hereby amended as follows:
The section titled "Capitalization" beginning on page SUP-2 of the Prospectus Supplement is deleted in its entirety and replaced with the following:
CAPITALIZATION
The Fund may offer and sell up to 5,872,794 of our common shares, no par value per share, from time to time through the Sub-Placement Agent as sub-placement agent under this prospectus supplement and the accompanying prospectus. There is no guarantee that there will be any sales of our common shares pursuant to this prospectus supplement and the accompanying prospectus. The table below assumes that we will sell 5,872,794 common shares (the number of common shares remaining to be sold under the current sales agreement as of September 9, 2024) at a price of $11.48 per share (the last reported sale price per share of our common shares on Nasdaq on September 9, 2024). The table below shows our historical capitalization as of April 30, 2024 and the estimated capitalization of the Fund assuming the sale of all 5,872,794 common shares that are subject to the sales agreement at a price of $11.48 per share, the last reported sales price per share of our common shares, on a pro forma, as adjusted basis as of September 9, 2024. Actual sales, if any, of the Fund's common shares under this prospectus supplement and accompanying prospectus may be different than as set forth in the table below. In addition, the price per share of any such sale may be greater or less than $11.48 per share, depending on the market price of the Fund's common shares at the time of any such sale and/or the Fund's net asset value ("NAV") for purposes of calculating the Minimum Price. The Fund and the Distributor will determine whether any sales of the Fund's common shares will be authorized on a particular day; the Fund and the Distributor, however, will not authorize sales of the Fund's common shares if the per share price of the shares is less than the Minimum Price. The Fund and the Distributor may elect not to authorize sales of the Fund's common shares on a particular day even if the per share price of the shares is equal to or greater than the Minimum Price, or may only authorize a fixed number of shares to be sold on any particular day. The Fund and the Distributor will have full discretion regarding whether sales of Fund common shares will be authorized on a particular day and, if so, in what amounts.
The following table sets forth our capitalization:
· on an actual basis as of April 30, 2024; and
· on a pro forma as further adjusted basis to reflect (1) the assumed sale of 5,872,794 of our common shares at $11.48 per share (the last reported sale price of our common shares on NASDAQ on September 9, 2024) in an offering under this prospectus supplement and the issuance 233,238 of our common shares through the Fund's dividend reinvestment plan, (2) the investment of net proceeds assumed from such offerings in accordance with our investment objections and policies, after deducting assumed aggregate commission of $674,197 (representing an estimated commission of 1% of the gross sales price in connection with sale of common shares), (3) the redemption of $33,250,000 of Series B MRP Shares on September 6, 2024, and (4) the issuance of $33,000,000 of Mandatory Redeemable Preferred Shares on September 9, 2024.

SUMMARY OF FUND EXPENSES
The following table and example contain information about the costs and expenses that common shareholders will bear directly or indirectly. In accordance with Commission requirements, the table below shows our expenses, including interest payments on borrowed funds, as a percentage of our average net assets as of September 9, 2024, and not as a percentage of gross assets or managed assets.
By showing expenses as a percentage of average net assets, expenses are not expressed as a percentage of all of the assets we invest. The table and example are based on our capital structure as of September 9, 2024. As of September 9, 2024, we had $248.8 million in borrowings outstanding, $132.75 million in outstanding preferred shares and additional structural leverage of $65.9 million, collectively representing 37.7% of managed assets as of that date.
| Shareholder Transaction Expenses | | | |
| Sales Load (as a percentage of offering price) | | | 1.00 | %(1) |
| Offering Expenses Borne by the Fund (as a percentage of offering price) | | | — | % |
| Dividend Reinvestment Plan Fees (per sales transaction fee)(2) | | $ | 15.00 | |
| Annual Expenses | | Percentage of Average Net
Assets Attributable to
Common Shareholders | |
| Management Fee(3) | | | 1.28 | % |
| Interest Payments on Borrowed Funds(4) | | | 2.53 | % |
| Preferred Stock Dividend Payments(5) | | | 0.63 | % |
| Other Expenses(6) | | | 0.10 | % |
| Total Annual Expenses | | | 4.54 | % |
Example:
The following example illustrates the expenses that common shareholders would pay on a $1,000 investment in common shares, assuming (1) net annual expenses of 4.54% of net assets attributable to common shareholders; (2) a 5% annual gross return; and (3) all distributions are reinvested at net asset value:
| | | 1 Year | | | 3 Years | | | 5 Years | | | 10 Years | |
| Total Expenses Paid by Common Shareholders(7) | | $ | 55 | | | $ | 146 | | | $ | 238 | | | $ | 471 | |
The example should not be considered a representation of future expenses. Actual expenses may be greater or less than those assumed. Moreover, our actual rate of return may be greater or less than the hypothetical 5% return shown in the example.
(1) Represents the estimated commission with respect to the Fund's common shares being sold in this offering. There is no guarantee that there will be any sales of the Fund's common shares pursuant to this prospectus supplement and the accompanying prospectus. Actual sales of the Fund's common shares under this prospectus supplement and the accompanying prospectus, if any, may be less than as set forth under "Capitalization" above. In addition, the price per share of any such sale may be greater or less than the price set forth under "Capitalization" above, depending on the market price of the Fund's common shares at the time of any such sale.
(2) Shareholders will pay a $15.00 transaction fee plus a $0.02 per share brokerage charge if they direct Computershare Shareowner Services LLC (the "Plan Agent") to sell common shares held in an account of the Fund's Automatic Dividend Reinvestment Plan (the "Plan"). In addition, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open-market purchases in connection with the reinvestment of dividends or distributions. If a participant elects to have the Plan Agent sell part or all of his or her common shares and remit the proceeds, such participant will be charged his or her pro rata share of brokerage commissions on the shares sold. See "Dividends and Distributions on Common Shares; Automatic Dividend Reinvestment Plan" on page 78 of the accompanying prospectus.
(3) The Fund pays Calamos an annual management fee, payable monthly in arrears, for its investment management services in an amount equal to 0.80% of the Fund's average weekly managed assets. In accordance with the requirements of the Commission, the table above shows the Fund's management fee as a percentage of average net assets attributable to common shareholders. By showing the management fee as a percentage of net assets, the management fee is not expressed as a percentage of all of the assets the Fund intends to invest. For purposes of the table, the management fee has been converted to 1.28% of the Fund's average weekly net assets as of September 9, 2024 by dividing the total dollar amount of the management fee by the Fund's average weekly net assets (managed assets less outstanding leverage).
(4) Reflects interest expense paid on $265 million in average borrowings under the Fund's Amended and Restated Liquidity Agreement with State Street Bank and Trust Company, plus $50 million in additional average structural leverage related to certain securities lending programs, as described in the accompanying prospectus under "Leverage."
(5) Reflects estimated dividend expense on $132.75 million aggregate liquidation preference of mandatory redeemable preferred shares ("MRP Shares" or "MRPS") outstanding. See "Prospectus Summary — Use of Leverage by the Fund" and "Leverage" in the accompanying prospectus for additional information.
(6) "Other Expenses" are based on estimated amounts for the Fund's current fiscal year.
(7) The example includes sales load and estimated offering costs.

Additional information regarding the Fund's preferred shares is included below under "Mandatory Redeemable Preferred Shares."
The section titled "Mandatory Redeemable Preferred Shares" beginning on page 36 of the Prospectus is deleted in its entirety and replaced with the following:
Mandatory Redeemable Preferred Shares
On September 6, 2017, the Fund completed a private placement of 1,340,000 Series C MRP Shares. On August 24, 2021, the Fund completed a private placement of 1,320,000 Series D MRP Shares and 1,330,000 Series E MRP Shares. On September 9, 2024, the Fund completed a private placement of 1,320,000 Series G MRP Shares. Each MRP Share has a liquidation preference of $25.00, resulting in an aggregate liquidation preference of $132.75 million for all MRP Shares.
The holders of MRP Shares for the Fund ("MRP Shareholders") are entitled to receive monthly cash dividends, payable on the first business day (a "Dividend Payment Date") of each month following issuance.
Subject to adjustment as described below under "MRP Shares Dividends," the dividend rate per annum (the "Applicable Rate") for each class of MRP Shares is as follows:
| MRP Shares | | Applicable Rate | |
| Series C MRP Shares | | | 4.24 | % |
| Series D MRP Shares | | | 2.45 | % |
| Series E MRP Shares | | | 2.68 | % |
| Series G MRP Shares | | | 6.24 | % |
The MRP Shares have a term redemption date of September 6, 2027 for the Series C MRP Shares, August 24, 2026 for the Series D MRP Shares, May 24, 2027 for the Series E MRP Shares, and September 9, 2029 for the Series G MRP Shares.
Previously, the Series C MRP Shares had been assigned a rating of "AA" by Fitch Ratings, Inc. ("Fitch"). As of December 17, 2020, Kroll Bond Rating Agency LLC ("KBRA") replaced Fitch as the rating agency for the Series C MRP Shares and the Series C MRP Shares have been assigned a rating of 'AA-' by KBRA. As of August 24, 2021, the Series D MRP Shares and Series E MRP Shares have each been assigned a rating of ‘AA-’ by KBRA. As of September 9, 2024, the Series G MRP Shares have been assigned a rating of AA- by KBRA. If the ratings of the MRP Shares are downgraded, the Fund's dividend expense may increase, as described below.
Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the MRP Shareholders will be entitled to receive a preferential liquidating distribution equal to $25.00 per MRP Share plus accrued and unpaid dividends, after satisfaction of claims of creditors of the Fund, but before any distribution of assets is made to common shareholders.
MRP Shares Dividends. If, on the first day of the monthly dividend period immediately preceding a Dividend Payment Date (each such period a "Dividend Period"), Series C MRP Shares is rated no less than "A" by Fitch (and no less than the equivalent of such rating by some other NRSRO, if any, other than Fitch, such as KBRA, providing a rating for the MRP Shares pursuant to the request of the Fund) or with respect to Series D MRP Shares, Series E MRP Shares or Series G MRP Shares, by KBRA (or lower than the equivalent of such rating by any Other Rating Agency), then the dividend rate for such period (the "Dividend Rate") will be equal to the Applicable Rate for such series.
If, on the first day of a Dividend Period, the credit rating assigned on any date to Series C MRP Shares by Fitch (or some other NRSRO then rating any series of the outstanding MRP Shares pursuant to the request of the Fund, such as KBRA) is lower than a rating of "A" (or lower than the equivalent of such rating by such other rating agency), or with respect to Series D MRP Shares, Series E MRP Shares or Series G MRP Shares, are rated lower than the equivalent of "A" by KBRA (or lower than the equivalent of such rating by any Other Rating Agency) the Dividend Rate applicable to such series of outstanding MRP Shares for such Dividend Period shall be the Applicable Rate plus the enhanced dividend amount (which shall not be cumulative) set opposite the lowest of such ratings in the table below:
Fitch Rating or KBRA Rating
(Or Equivalent by an Other
Rating Agency) | | Enhanced
Dividend Amount | |
| “A-” | | | 0.5 | % |
| “BBB+” to “BBB-” | | | 2.0 | % |
| “BB+” or below | | | 4.0 | % |
A 4.0% premium in addition to the Applicable Rate may apply when the Fund fails to maintain a current credit rating, and a 5.0% premium may apply when the Fund fails to make timely payments with regard to the MRP Shares (subject to cure periods in each case).
Limitation on Common Share Distributions. With regard to the Series C MRP Shares, so long as any MRP Shares are outstanding, the Fund will not declare, pay or set apart for payment any dividend or other distribution (other than non-cash distributions) with respect to Fund shares ranking junior to or on parity with the MRP Shares, unless (1) the Fund has satisfied the MRP Shares Overcollateralization Test (as defined below) on at least one "valuation date" in the preceding 65 calendar days, (2) immediately after such transaction the Fund would satisfy the MRP Shares Asset Coverage Test (as defined below), (3) full cumulative dividends on the MRP Shares due on or prior to the date of the transaction have been declared and paid to the holders of MRP Shares and (4) the Fund has redeemed the full number of MRP Shares required to be redeemed by any provision for mandatory redemption or deposited sufficient monies with the Fund's paying agent for that purpose, subject to certain grace periods and exceptions.
MRP Shares Asset Coverage Test: Asset coverage with respect to all outstanding senior securities and preferred shares, including the MRP Shares, determined in accordance with Section 18(h) of the 1940 Act, on the basis of values calculated as of a time within 48 hours (not including Sundays or holidays) next preceding the time of determination, must be greater than or equal to 225%.
MRP Shares Overcollateralization Test: So long as Fitch or any other NRSRO, such as KBRA, is then rating any class of the outstanding MRP Shares pursuant to the request of the Fund, satisfaction of only those overcollateralization ratios applicable to closed-end fund issuers with the same rating(s) as the Fund's MRP Shares' then-current rating(s) issued by Fitch or such other NRSRO, such as KBRA, by application of the applicable rating agency guidelines.
With regard to Series D MRP Shares, Series E MRP Shares or Series G MRP Shares, for so long as any MRP Shares are Outstanding, the Fund will not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or options, warrants or rights to subscribe for or purchase, Common Shares or other shares of beneficial interest, if any, ranking junior to the MRP Shares as to dividends or upon liquidation (collectively "non-cash distributions")) with respect to Common Shares or any other shares of the Series or Fund ranking junior to or on a parity with the MRP Shares as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Fund ranking junior to the MRP Shares as to dividends and upon liquidation) or any such parity shares (except by conversion into or exchange for shares of the Fund ranking junior to or on a parity with the MRP Shares as to dividends and upon liquidation), unless (1) immediately after such transaction the Fund would satisfy the MRP Shares Asset Coverage Test, (2) full cumulative dividends on the MRP Shares due on or prior to the date of the transaction have been declared and paid to the holders of MRP Shares, and (3) the Fund has redeemed the full number of MRP Shares required to be redeemed by any provision for mandatory redemption contained in Section 3(a) or deposited sufficient monies with the Paying Agent for that purpose (without regard to the provisions of the Special Proviso); provided that the Fund may make any distributions reasonably necessary for the Fund to continue to qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code and to avoid excise tax under Section 4982 of the Internal Revenue Code ("Tax Required Payments"). For the avoidance of doubt, any such Tax Required Payments would only be paid to holders of Common Shares after full cumulative dividends due on or prior to the date of the applicable distribution and any mandatory redemptions occurring on or prior to the date of the applicable distribution have been paid to the holders of Preferred Shares.
The terms of the MRP Shares and rights and preferences of the holders of the MRP Shares are set forth in the Statement of Preferences of Series C Mandatory Redeemable Preferred Shares, Series D Mandatory Redeemable Preferred Shares, Series E Mandatory Redeemable Preferred Shares, and Series G Mandatory Redeemable Preferred Shares of the Fund.
Redemption. The terms of the MRP Shares provide that: (i) the Fund may redeem the MRP Shares at its option at the liquidation preference plus accrued and unpaid dividends and plus a make-whole premium, subject to notice and other requirements; (ii) the Fund is required to redeem the MRP Shares upon failure to satisfy the MRP Shares Asset Coverage Test (tested monthly) or MRP Shares Overcollateralization Test (tested weekly), subject to cure periods; and (iii) the Fund is required to redeem the MRP Shares on the term redemption date of September 6, 2027 for the Series C MRP Shares, August 24, 2026 for the Series D MRP Shares, May 24, 2027 for the Series E MRP Shares, and September 9, 2029 for the Series G MRP Shares.
Voting Rights. Except as otherwise required in the prospectus, the governing documents of the Fund, or as otherwise required by applicable law, the Fund's preferred shareholders, including the MRP Shares, have one vote per share and vote together with the Fund's common shareholders as a single class. The 1940 Act grants the holders of preferred stock the right to elect at least two Trustees at all times (the "Preferred Share Trustees") and the remaining Trustees will be elected by the holders of common stock and preferred stock voting as a single class. Except during any time when the Fund has failed to make a dividend or redemption payment in respect of MRP Shares outstanding, the holders of MRP Shares have agreed to vote in accordance with the recommendation of the Board of Trustees on any matter submitted to them for their vote or to the vote of shareholders of the Fund generally.
With respect to the MRP Shares, William R. Rybak and Virginia G. Breen were designated by the Board of Trustees as the Preferred Share Trustees of the Fund. As of September 9, 2024, there were five other Trustees of the Fund, Ms. Stuckey and Messrs. Calamos, Neal, Toub and Wennlund. See "Management of the Fund" in the Fund's statement of additional information. The Fund's preferred shareholders, including the MRP Shareholders, are entitled to elect a majority of the Trustees of the Fund during any period when (i) at least two years' accumulated dividends on the preferred stock are due and unpaid or (ii) the preferred shares are otherwise entitled under the 1940 Act to elect a majority of the Trustees of the Fund. The MRP Shareholders have certain additional customary voting rights pursuant to the MRP Shares governing documents and the 1940 Act.
The summary information regarding the MRP Shares contained herein is qualified in its entirety by reference to the Statement of Preferences and other documents related to the terms and conditions and the offering of the MRP Shares.
The section titled "Effects of Leverage" beginning on page 40 of the Prospectus is deleted in its entirety and replaced with the following:
The SSB Agreement provides for credit availability for the Fund, such that it may borrow up to $430 million. As of September 9, 2024, the Fund had utilized $314.7 million of the $430 million available under the SSB Agreement ($248.8 million in borrowings outstanding, and $65.9 million in structural leverage consisting of collateral received from SSB in connection with securities on loan), representing 26.5% of the Fund's managed assets as of that date, and had $132.75 million of MRP Shares outstanding, representing 11.2% of the Fund's managed assets. Combined, the borrowings under the SSB Agreement and the outstanding MRP Shares represented 37.7% of the Fund's managed assets. Interest on the SSB Agreement is charged on the drawn amount at the rate of the Overnight Bank Financing Rate (“OBFR”) plus 0.52%, payable monthly in arrears. Interest on overdue amounts or interest on the drawn amount paid during an event of default will be charged at OBFR plus 2.52%. These rates represent floating rates of interest that may change over time. The SSB Agreement has a commitment fee of 0.10% of any undrawn amount. As of September 9, 2024, the interest rate charged under the SSB Agreement was 5.8%.
The Fund's MRP Shareholders are entitled to receive monthly cash dividends, at a currently effective dividend rate per annum for each series of MRP Shares as follows (subject to adjustment as described above in "Mandatory Redeemable Preferred Shares"): 4.24% for Series C MRP Shares, 2.45% for Series D MRP Shares, 2.68% for Series E MRP Shares, and 6.24% for Series G MRP Shares.
To cover the interest expense on the borrowings under the SSB Agreement (including "net income" payments made with respect to borrowings offset by collateral for securities on loan) and the dividend payments associated with the MRP Shares, based on rates in effect on September 9, 2024, the Fund's portfolio would need to experience an annual return of 2.68% (before giving effect to expenses associated with senior securities).
Leverage is a speculative technique that could adversely affect the returns to common shareholders. Leverage can cause the Fund to lose money and can magnify the effect of any losses. To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Fund's return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage or if the Fund incurs capital losses, the return of the Fund will be less than if leverage had not been used, and therefore the amount available for distribution to common shareholders as dividends and other distributions will be reduced or potentially eliminated.
The Fund will pay, and common shareholders will effectively bear, any costs and expenses relating to any borrowings and to the issuance and ongoing maintenance of preferred shares, including the MRP Shares, or debt securities. Such costs and expenses include the higher management fee resulting from the use of any such leverage, offering and/or issuance costs, and interest and/or dividend expense and ongoing maintenance.
Certain types of borrowings may result in the Fund being subject to covenants in credit agreements, including those relating to asset coverage, borrowing base and portfolio composition requirements and additional covenants that may affect the Fund's ability to pay dividends and distributions on common shares in certain instances. The Fund may also be required to pledge its assets to the lenders in connection with certain types of borrowings. The Fund may be subject to certain restrictions on investments imposed by guidelines of and covenants with rating agencies for the preferred shares or short-term debt instruments issued by the Fund. These guidelines and covenants may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act.
Because Calamos' investment management fee is a percentage of the Fund's managed assets, Calamos' fee will be higher if the Fund is leveraged and Calamos will have an incentive to be more aggressive and leverage the Fund. Consequently, the Fund and Calamos may have differing interests in determining whether to leverage the Fund's assets. Any additional use of leverage by the Fund effected through new, additional or increased credit facilities or the issuance of preferred shares would require approval by the Board of Trustees of the Fund.
The following table illustrates the hypothetical effect on the return to a holder of the Fund's common shares of the leverage obtained by us (and utilized on September 9, 2024). The purpose of this table is to assist you in understanding the effects of leverage. As the table shows, leverage generally increases the return to common shareholders when portfolio return is positive and greater than the cost of leverage and decreases the return when the portfolio return is negative or less than the cost of leverage. The figures appearing in the table are hypothetical and actual returns may be greater or less than those appearing in the table.

| Corresponding Common Share Return(1) | | | (19.17 | )% | | | (11.17 | )% | | | (3.17 | )% | | | 4.83 | % | | | 12.83 | % |

The Board of Trustees, without shareholder approval but subject to the governing documents of the Fund and the MRP Shares, is authorized to amend the Agreement and Declaration of Trust and By-Laws to reflect the terms of any such class or series.

Such costs and expenses include the higher management fee resulting from the use of any such leverage, offering and/or issuance costs, and interest and/or dividend expense and ongoing maintenance.

Interest on the SSB Agreement is charged on the drawn amount at the rate of OBFR plus 0.52%, payable monthly in arrears. Interest on overdue amounts or interest on the drawn amount paid during an event of default will be charged at OBFR plus 2.52%. The SSB Agreement has a commitment fee of 0.10% of any undrawn amount.
