Experience and Foresight

Calamos is a trusted and leading provider of closed-end funds that use a diversified blend of convertible securities, equities, fixed income, and alternative investments across innovative investment strategies to support competitive distributions throughout a market cycle.

Our Managed Distribution Policy

(for Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income Fund, and Calamos Long/Short Equity & Dynamic Income Fund)

Closed-end fund investors often seek a steady stream of income. Recognizing this important need, certain Calamos closed-end funds adhere to a managed distribution policy in which we aim to provide consistent monthly distributions through the disbursement of the following:

• Net investment income

• Net realized short-term capital gains

• Net realized long-term capital gains

• And, if necessary, return of capital

We set distributions at levels that we believe are sustainable for the long term. Each Fund's current monthly distribution per share as of April 30, 2024 is as follows:

• Calamos Convertible Opportunities and Income Fund: $0.0950

• Calamos Convertible and High Income Fund: $0.1000

• Calamos Strategic Total Return Fund: $0.1025

• Calamos Dynamic Convertible and Income Fund: $0.1950

• Calamos Long/Short Equity & Dynamic Income Fund: $0.1400

Our team focuses on delivering an attractive monthly distribution, while maintaining a long-term emphasis on risk management. The level of a Fund's distribution can be greatly influenced by market conditions, including the interest rate environment, the individual performance of securities held by the funds, our view of retaining leverage, fund tax considerations, and regulatory requirements.

You should not draw any conclusions about a Fund's investment performance from the amount of its distribution or from the terms of a Fund's plan. The Funds' Board of Trustees may amend or terminate the managed distribution policy at any time without prior notice to the Fund's shareholders. However, at this time there are no reasonably foreseeable circumstances that might cause the termination of a Fund's managed distribution policy.

For more information about any of the Calamos closed-end funds, we encourage you to contact your financial advisor or Calamos Investments at 800.582.6959 (Monday through Friday from 8:00 a.m. to 6:00 p.m., Central Time). You can also visit us at www.calamos.com.

* Net investment income (loss) calculated based on average shares method.

(a) Amount is less than $0.005 per common share.

(b) Total investment return is calculated assuming a purchase of common stock on the opening of the first day and a sale on the closing of the last day of the period reported. Dividends and distributions are assumed, for purposes of this calculation, to be reinvested at prices obtained under the Fund's dividend reinvestment plan. Total return is not annualized for periods less than one year. Brokerage commissions are not reflected. NAV per share is determined by dividing the value of the Fund's portfolio securities, cash and other assets, less all liabilities, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the Fund at a given time. Common share market price is influenced by a range of factors, including supply and demand and market conditions.

(c) Ratio of net expenses, excluding interest expense on Notes Payable and interest expense and amortization of offering costs on Mandatory Redeemable Preferred Shares, to average net assets was 1.38%, 1.38%, 1.34%, 1.23%, 1.26%, 1.29%, 1.28%, 1.24%, 1.24%, 1.50%, and 1.18%, respectively.

(d) Annualized.

(e) Calculated by subtracting the Fund's total liabilities (not including Notes payable and Mandatory Redeemable Preferred Shares) from the Fund's total assets and dividing this by the amount of Notes payable outstanding, and by multiplying the result by 1,000.

(f) Calculated by subtracting the Fund's total liabilities (not including Notes payable and Mandatory Redeemable Preferred Shares) from the Fund's total assets and dividing this by the amount of Mandatory Redeemable Preferred Shares outstanding, and by multiplying the result by 25.

NAV per share is determined by dividing the value of the Fund's portfolio securities, cash and other assets, less all liabilities, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the Fund at a given time. Common share market price is influenced by a range of factors, including supply and demand and market conditions.

(d) Ratio of net expenses, excluding interest expense on Notes Payable and interest expense and amortization of offering costs on Mandatory Redeemable Preferred Shares, to average net assets was 1.70%, 1.70%, 1.65%, 1.51%, 1.56%, 1.61%, 1.57%, 1.51%, 1.52% and 1.56%, respectively.

(e) Annualized.

(f) Calculated by subtracting the Fund's total liabilities (not including Notes payable and Mandatory Redeemable Preferred Shares) from the Fund's total assets and dividing this by the amount of Notes payable outstanding, and by multiplying the result by 1,000.

(g) Calculated by subtracting the Fund's total liabilities (not including Notes payable and Mandatory Redeemable Preferred Shares) from the Fund's total assets and dividing this by the amount of Mandatory Redeemable Preferred Shares outstanding, and by multiplying the result by 25.

Notes to Financial Statements (Unaudited)

Note 1 – Organization and Significant Accounting Policies

Organization. Calamos Convertible Opportunities and Income Fund ("CHI"), Calamos Convertible and High Income Fund ("CHY"), Calamos Strategic Total Return Fund ("CSQ"), Calamos Dynamic Convertible and Income Fund ("CCD"), Calamos Global Dynamic Income Fund ("CHW"), Calamos Global Total Return Fund ("CGO"), and Calamos Long/Short Equity & Dynamic Income Trust ("CPZ") (each a "Fund", and collectively, the "Funds") were each organized as Delaware statutory trusts and are each registered under the Investment Company Act of 1940, as amended (the "1940 Act") as a diversified, closed-end management investment company.

Significant Accounting Policies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), and the Funds are each considered an investment company under U.S. GAAP and follow the accounting and reporting guidance set forth by the Financial Accounting Standards Board in Accounting Standards Codification (ASC) Topic 946: Financial Services—Investment Companies. Under U.S. GAAP, management is required to make certain estimates and assumptions at the date of the financial statements and actual results may differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued, have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Funds:

Fund Valuation. Each Board of Trustees ("Board" or "Trustees"), including a majority of the Trustees who are not "interested persons" of each Fund, have designated Calamos Advisors LLC ("Calamos Advisors", or the "Advisor") to perform fair valuation determinations related to all Funds' investments under the oversight of the Board. As "valuation designee" Calamos Advisors has adopted policies and procedures to guide the determination of the net asset value ("NAV") on any day on which each Fund's NAV is determined. The valuation of each Fund's investments is in accordance with these procedures.

Funds' securities that are traded on U.S. securities exchanges, except option securities, are valued at the official closing price, which is the last current reported sales price on its principal exchange at the time the Fund determines its NAV. Securities traded in the over-the-counter market and quoted on The NASDAQ Stock Market are valued at the NASDAQ Official Closing Price, as determined by NASDAQ, or lacking a NASDAQ Official Closing Price, the last current reported sale price on NASDAQ at the time the Fund determines its NAV. When a last sale or closing price is not available, equity securities, other than option securities, that are traded on a U.S. securities exchange and other equity securities traded in the over-the-counter market are valued at the mean between the most recent bid and asked quotations on its principal exchange in accordance with guidelines adopted by the Board. Each option security traded on a U.S. securities exchange is valued at the mid-point of the consolidated bid/ask quote for the option security, also in accordance with guidelines adopted by the Board of Trustees. Each over-the-counter option that is not traded through the Options Clearing Corporation is valued either by an independent pricing agent approved by the Board or based on a quotation provided by the counterparty to such option under the ultimate supervision of the Board.

Fixed income securities, bank loans, certain convertible preferred securities, and non-exchange traded derivatives are normally valued by independent pricing services or by dealers or brokers who make markets in such securities. Valuations of such fixed income securities, bank loans, certain convertible preferred securities, and non-exchange traded derivatives consider yield or price of equivalent securities of comparable quality, coupon rate, maturity, type of issue, trading characteristics and other market data and do not rely exclusively upon exchange or over-the-counter prices.

Trading on European and Far Eastern exchanges and over-the-counter markets is typically completed at various times before the close of business on each day on which the New York Stock Exchange ("NYSE") is open. Each security trading on these exchanges or in over-the-counter markets may be valued utilizing a systematic fair valuation model provided by an independent pricing service approved by the Board of Trustees. The valuation of each security that meets certain criteria in relation to the valuation model is systematically adjusted to reflect the impact of movement in the U.S. market after the foreign markets close. Securities that do not meet the criteria, or that are principally traded in other foreign markets, are valued as of the last reported sale price at the time each Fund determines its NAV, or when reliable market prices or quotations are not readily available, at the mean between the most recent bid and asked quotations as of the close of the appropriate exchange or other designated time. Trading of foreign 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 each Fund's NAV is not calculated.

If the Advisor's pricing committee determines that the valuation of a security in accordance with the methods described above is not reflective of a fair value for such security, the security is valued at a fair value by the pricing committee.

CALAMOS CLOSED-END FAMILY OF FUNDS SEMIANNUAL REPORT
146

Notes to Financial Statements (Unaudited)

The Funds also may use fair value pricing, pursuant to policies and procedures adopted by Calamos Advisors, if trading in the security is halted or if the value of a security it holds is materially affected by events occurring before a Fund's pricing time but after the close of the primary market or exchange on which the security is listed. Those procedures may utilize valuations furnished by pricing services approved by Calamos Advisors, 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 of securities is employed, the prices of securities used by each Fund to calculate its NAV may differ from market quotations or official closing prices. There can be no assurance that each Fund could purchase or sell a portfolio security at the price used to calculate each Fund's NAV.

Various inputs are used to determine the value of each Fund's investments. These inputs are categorized into three broad levels as follows:

• Level 1 – Prices are determined using inputs from unadjusted quoted prices from active markets (including securities actively traded on a securities exchange) for identical assets.

• Level 2 – Prices are determined using significant observable market inputs other than unadjusted quoted prices, including quoted prices of similar securities, fair value adjustments to quoted foreign securities, interest rates, credit risk, prepayment speeds, and other relevant data.

• Level 3 – Prices reflect unobservable market inputs (including each Fund's own judgments about assumptions market participants would use in determining fair value) when observable inputs are unavailable.

Debt securities are valued based upon evaluated prices received from an independent pricing service or from a dealer or broker who makes markets in such securities. Pricing services utilize various observable market data and as such, debt securities are generally categorized as Level 2. The levels are not necessarily an indication of the risk or liquidity of each Fund's investments. The summary of the inputs used in valuing each Fund's holdings are available after each Fund's Schedule of Investments.

Investment Transactions. Investment transactions are recorded on a trade date basis as of April 30, 2024. Net 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 original issue and market 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 the information becomes available after the ex-dividend date.

Foreign Currency Translation. Values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using a rate quoted by a major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service.

The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign currency gains or losses arise from disposition of foreign currency, the difference in the foreign exchange rates between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the ex-date or accrual date and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes (due to the changes in the exchange rate) in the value of foreign currency and other assets and liabilities denominated in foreign currencies held at period end.

Allocation of Expenses Among Funds. Expenses directly attributable to each respective Fund are charged to the Fund; certain other common expenses of Calamos Advisors Trust, Calamos Investment Trust, Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Global Total Return Fund, Calamos Global Dynamic Income Fund, Calamos Dynamic Convertible and Income Fund, Calamos Long/Short Equity & Dynamic Income Trust, Calamos Antetokounmpo Sustainable Equities Trust, and Calamos ETF Trust are allocated proportionately among each fund to which the expenses relate in relation to the net assets of each fund or on another reasonable basis.

Notes to Financial Statements (Unaudited)

Income Taxes. No provision has been made for U.S. income taxes because each Funds' policy is to continue to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended, and distribute to shareholders substantially all of the respective Funds' taxable income and net realized gains.

Dividends and distributions paid to common shareholders are recorded on the ex-dividend date. The amount of dividends and distributions from net investment income and net realized capital gains is determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. To the extent these "book and tax" differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment. These differences are primarily due to differing treatments for foreign currency transactions, contingent payment debt instruments and methods of amortizing and accreting for fixed income securities. The financial statements are not adjusted for temporary differences.

Distributions to holders of Mandatory Redeemable Preferred Shares ("MRPS") as described in Note 8 are accrued on a daily basis and are treated as an operating expense due to the fixed term of the obligation. The distributions are shown on the Statement of Operations as Interest expense and amortization of offering costs on MRPS. For tax purposes, the distributions made to the holders of the MRPS are treated as dividends.

The Funds recognized no liability for uncertain tax positions. A reconciliation is not provided as the beginning and ending amounts of unrecognized benefits are zero, with no interim additions, reductions or settlements. Tax years 2021 – 2023 remain subject to examination by the U.S. and the State of Illinois tax jurisdictions.

Indemnifications. Under the Funds' organizational documents, each Fund is obligated to indemnify its officers and trustees against certain liabilities incurred by them by reason of having been an officer or trustee of the Fund. In addition, in the normal course of business, a Fund may enter into contracts that provide general indemnifications to other parties. A Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against a Fund that have not yet occurred. Currently, the Funds' management expects the risk of material loss in connection to a potential claim to be remote.

Note 2 – Investment Adviser and Transactions With Affiliates Or Certain Other Parties

Pursuant to an investment advisory agreement with Calamos Advisors, each Fund pays an annual fee, payable monthly based on the average weekly managed assets of the Fund, as shown below:

FUND	ANNUAL RATE
Convertible Opportunities and Income Fund		0.80	%
Convertible and High Income Fund		0.80	%
Strategic Total Return Fund		1.00	%
Dynamic Convertible and Income Fund		1.00	%
Global Dynamic Income Fund		1.00	%
Global Total Return Fund		1.00	%
Long/Short Equity & Dynamic Income Trust		1.35	%

Each Fund reimburses Calamos Advisors for a portion of compensation paid to each Trust's Chief Compliance Officer. This compensation is reported as part of the "Trustees' fees and officer compensation" expense on the Funds' Statements of Operations.

The Funds have adopted a deferred compensation plan (the "Plan"). Under the Plan, a trustee who is not an "interested person" (as defined in the 1940 Act) and has elected to participate in the Plan (a "participating trustee") may defer receipt of all or a portion of his compensation from the Trust. The deferred compensation payable to the participating trustee is credited to the trustee's deferral account as of the business day such compensation would have been paid to the participating trustee. The value of amounts deferred for a participating trustee is determined by reference to the change in value of Class I shares of one or more funds of the Calamos Investment Trust designated by the participant. The value of the account increases with contributions to the account or with increases in the value of the measuring shares, and the value of the account decreases with withdrawals from the account or with declines in the value of the measuring shares.

* Because tax adjustments are calculated annually, the above table does not reflect tax adjustments. For the previous fiscal year's federal income tax information, please refer to the Notes to Financial Statements section in the Funds' most recent annual report.

Each Fund intends to make monthly distributions from its income available for distribution, which consists of each Fund's dividends and interest income after payment of Fund expenses, and net realized gains on investments. At least annually, each Fund intends to distribute all or substantially all of its net realized capital gains, if any. Distributions are recorded on the ex-dividend date. Each Fund distinguishes between distributions on a tax basis and a financial reporting basis. Accounting principles generally accepted in the United States of America require that only distributions in excess of tax basis earnings

Notes to Financial Statements (Unaudited)

and profits be reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in-capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. Distributions in any year may include a return of capital component.

The tax character of distributions for the period ended April 30, 2024 will be determined at the end of each Fund's current fiscal year. Distributions during the fiscal period ended October 31, 2023 were characterized for federal income tax purposes as follows:

	YEAR ENDED OCTOBER 31, 2023

Note 5 – Short Sales

Calamos Global Dynamic Income Fund and Calamos Long/Short Equity & Dynamic Income Trust may sell securities short. Securities sold short represent obligations to deliver the securities at a future date. Each Fund may sell a security it does not own in anticipation of a decline in the value of that security before the delivery date. When a Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. Dividends paid

on securities sold short are disclosed as an expense on the Statements of Operations. A gain, limited to the price at which a Fund sold the security short, or a loss, unlimited in size, will be realized upon the termination of a short sale.

To secure its obligation to deliver to the broker-dealer the securities sold short, a Fund must segregate an amount of cash or liquid securities with its custodian equal to any excess of the current market value of the securities sold short over any cash or liquid securities deposited as collateral with the broker in connection with the short sale (not including the proceeds of the short sale). As a result of that requirement, a Fund will not gain any leverage merely by selling short, except to the extent that it earns interest or other income or gains on the segregated cash or liquid securities while also being subject to the possibility of gain or loss from the securities sold short.

Note 6 – Derivative Instruments

Foreign Currency Risk. Each Fund may engage in portfolio hedging with respect to changes in currency exchange rates by entering into forward 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, among other things, movement in the value of the foreign currency relative to the U.S. dollar and the ability of the counterparty to perform.

To mitigate the counterparty risk, a Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs over-the-counter derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, a Fund may, under certain circumstances, offset with the counterparty certain derivative financial instrument's payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Generally, collateral is exchanged between a Fund and the counterparty and the amount of collateral due from a Fund or to a counterparty has to exceed a minimum transfer amount threshold before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. When a Fund is required to post collateral under the terms of a derivatives transaction and master netting agreement, a Fund's custodian holds the collateral in a segregated account, subject to the terms of a tri-party agreement among a Fund, the custodian and the counterparty. The master netting agreement and tri-party agreement provide, in relevant part, that the counterparty may have rights to the amounts in the segregated account in the event that a Fund defaults in its obligation with respect to the derivative instrument that is subject to the collateral requirement. When a counterparty is required to post collateral under the terms of a derivatives transaction and master netting agreement, the counterparty delivers such amount to a Fund's custodian. The master netting agreement provides, in relevant part, that the Fund may have rights to such collateral in the event that the counterparty defaults in its obligation with respect to the derivative instrument that is subject to the collateral requirement. Generally before a default, neither a Fund nor the counterparty may resell, rehypothecate, or repledge any collateral that it receives.

For financial reporting purposes, the Funds do not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statements of Assets and Liabilities. Each Fund's net counterparty exposure, if any, is reflected in the Schedules of Investments. The net unrealized gain, if any, represents the credit risk to the Fund on a forward foreign currency contract. The contracts are valued daily at forward foreign exchange rates. The Fund realizes a gain or loss when a position is closed or upon settlement of the contracts. There were no open forward foreign currency contracts for any of the Funds at April 30, 2024.

Equity Risk. Each Fund may engage in option transactions and in doing so achieves similar objectives to what it would achieve through the sale or purchase of individual securities. A call option, upon payment of a premium, gives the purchaser of the option the right to buy, and the seller of the option the obligation to sell, the underlying security, index or other instrument at the exercise price. A put option gives the purchaser of the option, upon payment of a premium, the right to sell, and the seller the obligation to buy, the underlying security, index, or other instrument at the exercise price.

To seek to offset some of the risk of a potential decline in value of certain long positions, each Fund may also purchase put options on individual securities, broad-based securities indexes or certain exchange-traded funds ("ETFs"). Each Fund may also seek to generate income from option premiums by writing (selling) options on a portion of the equity securities (including securities that are convertible into equity securities) in a Fund's portfolio, on broad-based securities indexes, or certain ETFs.

Notes to Financial Statements (Unaudited)

When a Fund purchases an option, it pays a premium and an amount equal to that premium is recorded as an asset. When a Fund writes an option, it receives a premium and an amount equal to that premium is recorded as a liability. The asset or liability is adjusted daily to reflect the current market value of the option. If an option expires unexercised, a Fund realizes a gain or loss to the extent of the premium received or paid. If an option is exercised, the premium received or paid is recorded as an adjustment to the proceeds from the sale or the cost basis of the purchase. The difference between the premium and the amount received or paid on a closing purchase or sale transaction is also treated as a realized gain or loss. 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. Gain or loss on written options and purchased options is presented separately on the Statements of Operations as net realized gain or loss on written options and net realized gain or loss on purchased options, respectively.

Options written by each Fund do not typically give rise to counterparty credit risk since options written obligate each Fund and not the counterparty to perform. Exchange traded purchased options have minimal counterparty credit risk to each Fund since the exchange's clearinghouse, as counterparty to such instruments, guarantees against a possible default. As of April 30, 2024, the Funds had outstanding purchased options and/or written options as listed on the Schedules of Investments.

Interest Rate Risk. Each Fund may engage in interest rate swaps primarily to hedge the interest rate risk on the Fund's borrowings (see Note 7—Notes Payable). An interest rate swap is a contract that involves the exchange of one type of interest rate for another type of interest rate. If interest rates rise, resulting in a diminution in the value of the Fund's portfolio, the Fund would receive payments under the swap that would offset, in whole or in part, such diminution in value; if interest rates fall, the Fund would likely lose money on the swap transaction. Unrealized gains are reported as an asset, and unrealized losses are reported as a liability on the Statements of Assets and Liabilities. The change in value of swaps, including accruals of periodic amounts of interest to be paid or received on swaps, is reported as change in net unrealized appreciation/depreciation on interest rate swaps in the Statements of Operations. A realized gain or loss is recorded in net realized gain (loss) on interest rate swaps in the Statements of Operations upon payment or receipt of a periodic payment or termination of the swap agreements. Swap agreements are stated at fair value. Notional principal amounts are used to express the extent of involvement in these transactions, but the amounts potentially subject to credit risk are much smaller. In connection with these contracts, securities may be identified as collateral in accordance with the terms of the respective swap contracts in the event of default or bankruptcy of each Fund. Please see the disclosure regarding ISDA Master Agreements under Foreign Currency Risk within this note.

Premiums paid to or by a Fund are accrued daily and included in realized gain (loss) when paid on swaps in the accompanying Statements of Operations. The contracts are marked-to-market daily based upon third party vendor valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the contract. Risks may exceed amounts recognized in the Statements of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms, counterparty's creditworthiness, and the possible lack of liquidity with respect to the contracts.

As of April 30, 2024, the Funds had no outstanding interest rate swap agreements.

As of April 30, 2024, the Funds had outstanding derivative contracts which are reflected on the Statements of Assets and Liabilities as follows:

Note 7 – Notes Payable

The Funds have each entered into an Amended and Restated Liquidity Agreement (the "SSB Agreement") with State Street Bank and Trust Company ("SSB") that allows each Fund to borrow up to a certain limit as shown in the table below, as well as engage in securities lending and securities repurchase transactions.

FUND	BORROWING LIMIT (IN MILLIONS)
Convertible Opportunities and Income Fund	$	430.0
Convertible and High Income Fund		480.0
Strategic Total Return Fund		1,130.0
Dynamic Convertible and Income Fund		370.0
Global Dynamic Income Fund		265.0
Global Total Return Fund		55.0
Long/Short Equity & Dynamic Income Trust		150.0

Advances under the SSB Agreement are secured by assets of the Funds that are held with the Funds' custodian in a separate account (the "pledged collateral"). Interest on the SSB Agreement was charged on the drawn amount at the rate of OBFR plus 0.52%. A commitment fee of 0.10% is payable on any undrawn balance. For the period ended April 30, 2024, the Funds borrowed according to the table below:

FUND	AVERAGE BORROWINGS (IN MILLIONS)		AVERAGE INTEREST RATE			TOTAL OUTSTANDING BORROWINGS (IN MILLIONS)		INTEREST RATE APPLICABLE TO BORROWINGS
Convertible Opportunities and Income Fund	$	314.4		5.94	%	$	314.4		5.84	%

Long/Short Equity & Dynamic Income Trust		120.0		5.94	%		120.0		5.84	%

Under the terms of the SSB Agreement, all securities lent through SSB must be secured continuously by collateral received in cash. Cash collateral received by SSB on behalf of the Fund is deposited by SSB in a custodial account of the Fund and then applied to repay borrowings under the SSB Agreement, such that the cash advanced to the Fund remains unchanged. Upon termination of a securities loan, SSB will advance to the Fund the cash collateral required to be returned by the Fund, or secure the appropriate amount through one or more securities lending transactions as the Fund's agent, and deposit the amount to a custodial account of the Fund and then subsequently return such amount to the securities borrower against return of the securities on loan. Again, the net cash to the Fund is unaltered. Only the composition of the advance is changed, and regardless of the composition of advances as between cash collateral for securities lending transactions or borrowings from SSB, they are not reflected separately in the Statement of Assets and Liabilities but as a component of the Notes Payable. The Fund has the right to recall securities which have been lent at any time. The securities lending arrangement with SSB involves characteristics common in arm's length relationships in which one party may benefit at the expense of the other party. As of April 30, 2024, the Funds had securities on loan under the SSB Agreement which are reflected in the Investment in securities, at value on the Statement of Assets and Liabilities and are shown in the table below. The borrowings are categorized as Level 2 within the fair value hierarchy.

Offering costs incurred by the Funds in connection with the MRPS issuance are aggregated with the outstanding liability and are being amortized to interest expense and amortization of offering costs on MRPS over the respective life of each series of MRPS and shown in the Statement of operations.

The MRPS are not listed on any exchange or automated quotation system. The MRPS are considered debt of the issuer; therefore, the liquidation preference, which approximates fair value of the MRPS, is recorded as a liability in each Fund's Statement of Assets and Liabilities net of deferred offering costs. The MRPS are categorized as Level 2 within the fair value hierarchy.

During the period ended April 30, 2024, all MRPS were rated `AA-' by Kroll Bond Rating Agency LLC ("KBRA"). If the ratings of the MRPS are downgraded, each Fund's dividend expense may increase, as described below.

Holders of MRPS are entitled to receive monthly cumulative cash dividends payable on the first business day of each month. The MRPS currently are rated "AA-" by KBRA. If on the first day of a monthly dividend period the MRPS of any class are rated lower than "A" by KBRA, the dividend rate for such period shall be increased by 0.5%, 2.0% or 4.0% according to an agreed upon schedule. The MRPS' dividend rate is also subject to increase during periods when a Fund has not made timely payments to MRPS holders and/or the MRPS do not have a current credit rating, subject to various terms and conditions. Dividends accrued and paid to the shareholders of MRPS are included in "Interest expense and amortization of offering costs on Mandatory Redeemable Preferred Shares" with each Fund's Statement of Operations.

With regard to the Series B and C MRPS, so long as any MRPS are outstanding, a 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 MRPS, unless (1) the Fund has satisfied the MRPS 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 MRPS Asset Coverage Test (as defined below), (3) full cumulative dividends on the MRPS due on or prior to the date of the transaction have been declared and paid to the holders of MRPS and (4) the Fund has redeemed the full number of

Notes to Financial Statements (Unaudited)

MRPS 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.

MRPS Asset Coverage Test: Asset coverage with respect to all outstanding senior securities and preferred shares, including the MRPS, 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%.

MRPS Overcollateralization Test: So long as Fitch or any other NSRSO, such as KBRA, is then rating any class of the outstanding MRPS 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 MRPS' then-current rating(s) issued by Fitch or such other NSRSO, such as KBRA, by application of the applicable rating agency guidelines.

In accordance with that certain Statement of Preferences governing the Series D, E and F MRPS, for so long as any MRPS are outstanding, a 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 MRPS 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 MRPS 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 MRPS 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 MRPS as to dividends and upon liquidation), unless (1) immediately after such transaction the Fund would satisfy the MRPS Asset Coverage Test, (2) full cumulative dividends on the MRPS due on or prior to the date of the transaction have been declared and paid to the Holders of MRPS, and (3) the Fund has redeemed the full number of MRPS 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 MRPS.

Except as otherwise required pursuant to the Funds' governing documents or applicable law, the holders of the MRPS have one vote per share and vote together with the holders of common stock of the Funds as a single class except on matters affecting only the holders of MRPS or the holders of common stock. Pursuant to the 1940 Act, holders of the MRPS have the right to elect at least two trustees of a Fund, voting separately as a class. Except during any time when a Fund has failed to make a dividend or redemption payment in respect of MRPS outstanding, the holders of MRPS have agreed to vote in accordance with the recommendation of the Board on any matter submitted to them for their vote or to the vote of shareholders of a Fund generally.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income Fund, Calamos Global Dynamic Income Fund, Calamos Global Total Return Fund, and Calamos Long/Short Equity & Dynamic Income Trust

Results of Review of Interim Financial Information

We have reviewed the accompanying statements of assets and liabilities of Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income Fund, Calamos Global Dynamic Income Fund, Calamos Global Total Return Fund, and Calamos Long/Short Equity & Dynamic Income Trust (the "Funds"), including the schedules of investments, as of April 30, 2024, the related statements of operations, changes in net assets, and the financial highlights for the six month period then ended; and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the statements of changes in net assets of the Funds and the financial highlights for each of the periods listed in the table below; and in our report dated December 20, 2023, we expressed an unqualified opinion on such statements of changes in net assets and financial highlights.

Individual Fund Comprising the Calamos Investment Trust	Statement of Changes in Net Assets	Financial Highlights
Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Global Dynamic Income Fund, and Calamos Global Total Return Fund	For the years ended October 31, 2023 and 2022	For the years ended October 31, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, and 2014

Calamos Long/Short Equity & Dynamic Income Trust	For the years ended October 31, 2023 and 2022	For the years ended October 31, 2023, 2022, 2021, and the period from November 29, 2019 (commencement of operations) through October 31, 2020

Basis for Review Results

This interim financial information is the responsibility of the Funds' management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements and financial highlights taken as a whole. Accordingly, we do not express such an opinion.

We have served as the auditor of one or more Calamos investment companies since 2003.

About Closed-End Funds

What is a Closed-End Fund?

A closed-end fund is a publicly traded investment company that raises its initial investment capital through the issuance of a fixed number of shares to investors in a public offering. Shares of a closed-end fund are listed on a stock exchange or traded in the over-the-counter market. Like all investment companies, a closed-end fund is professionally managed and offers investors a unique investment solution based on its investment objective approved by the fund's Board of Trustees.

Potential Advantages of Closed-End Fund Investing

• Defined Asset Pool Allows Efficient Portfolio Management—Although closed-end fund shares trade actively on a securities exchange, this doesn't affect the closed-end fund manager because there are no new investors buying into or selling out of the fund's portfolio.

• More Flexibility in the Timing and Price of Trades—Investors can purchase and sell shares of closed-end funds throughout the trading day, just like the shares of other publicly traded securities.

• Lower Expense Ratios—The expense ratios of closed-end funds are oftentimes less than those of mutual funds. Over time, a lower expense ratio could enhance investment performance.

• Closed-End Structure Makes Sense for Less-Liquid Asset Classes—A closed-end structure makes sense for investors considering less-liquid asset classes, such as high-yield bonds or micro-cap stocks.

• Ability to Put Leverage to Work—Closed-end funds may issue senior securities (such as preferred shares or debentures) or borrow money to "leverage" their investment positions.

• No Minimum Investment Requirements

OPEN-END MUTUAL FUNDS VERSUS CLOSED-END FUNDS

OPEN-END FUND				CLOSED-END FUND
Issues new shares on an ongoing basis				Generally issues a fixed number of shares
Issues common equity shares				Can issue common equity shares and senior securities such as preferred shares and bonds
Sold at NAV plus any sales charge				Price determined by the marketplace
Sold through the fund's distributor				Traded in the secondary market
Fund redeems shares at NAV calculated at the close of business day				Fund does not redeem shares

You can purchase or sell common shares of closed-end funds daily. Like any other stock, market price will fluctuate with the market. Upon sale, your shares may have a market price that is above or below net asset value and may be worth more or less than your original investment. Shares of closed-end funds frequently trade at a discount, which is a market price that is below their net asset value.

Leverage creates risks which may adversely affect return, including the likelihood of greater volatility of net asset value and market price of common shares and fluctuations in the variable rates of the leverage financing.

Each open-end or closed-end fund should be evaluated individually. Before investing carefully consider the fund's investment objectives, risks, charges and expenses.

Level Rate Distribution Policy

Using a Level Rate Distribution Policy to Promote Dependable Income and Total Return

Calamos Global Total Return Fund and Calamos Global Dynamic Income Fund have implemented a level rate distribution policy. The goal of the level rate distribution policy is to provide investors a predictable, though not assured, level of cash flow, which can either serve as a stable income stream or, through reinvestment, may contribute significantly to long-term total return.

We understand the importance that investors place on the stability of dividends and their ability to contribute to long-term total return, which is why we have instituted a level rate distribution policy for Calamos Global Total Return Fund and Calamos Global Dynamic Income Fund. Under the policy, monthly distributions paid may include net investment income, net realized short-term capital gains, and, if necessary, return of capital. In addition, a limited number of distributions per calendar year may include net realized long-term capital gains. Please refer to each Fund's financial statements for specific information about distributions made during the last fiscal year.

There is no guarantee that the Funds will realize capital gains in any given year. Distributions are subject to recharacterization for tax purposes after the end of the fiscal year. All shareholders with taxable accounts will receive written notification regarding the components and tax treatment for distributions via Form 1099-DIV. For purposes of maintaining the level rate distribution policy, the Funds may realize short-term capital gains on securities that, if sold at a later date, would have resulted in long-term capital gains. Maintenance of a level rate distribution policy may increase transaction and tax costs associated with the Funds.

Distributions from the Funds are generally subject to Federal income taxes.

Managed Distribution Policy

Using a Managed Distribution Policy to Promote Dependable Income and Total Return

Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income Fund, and Calamos Long/Short Equity & Dynamic Income Trust have implemented a managed distribution policy. The goal of the managed distribution policy is to provide investors a predictable, though not assured, level of cash flow, which can serve either as a stable income stream or, through reinvestment, may contribute significantly to long-term total return.

We understand the importance that investors place on the stability of dividends and their ability to contribute to long-term total return, which is why we have instituted a managed distribution policy for Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income Fund and Calamos Long/Short Equity & Dynamic Income Trust. Under the policy, monthly distributions paid may include net investment income, net realized short-term capital gains, net realized long-term capital gains and, if necessary, return of capital. Please refer to each Fund's financial statements for specific information about distributions made during the last fiscal year.

Distributions of capital decrease a Fund's total assets and total assets per share and, therefore, could have the effect of increasing a Fund's expense ratio. In general, the policy of fixing a Fund's distributions at a targeted rate does not affect a Fund's investment strategy. However, in order to make these distributions, on occasion the Funds may have to sell portfolio securities at a less than opportune time.

There is no guarantee that the Funds will realize capital gains in any given year. Distributions are subject to re-characterization for tax purposes after the end of the fiscal year. All shareholders with taxable accounts will receive written notification regarding the components and tax treatment for distributions via Form 1099-DIV.

Distributions from the Funds are generally subject to Federal income taxes.

Automatic Dividend Reinvestment Plan

Maximizing Investment with an Automatic Dividend Reinvestment Plan

The Automatic Dividend Reinvestment Plan offers a simple, cost-efficient and convenient way to reinvest your dividends and capital gains distributions in additional shares of each Fund, allowing you to increase your investment in the Fund.

Potential Benefits

• Compounded Growth: By automatically reinvesting with the Plan, you gain the potential to allow your dividends and capital gains to compound over time.

• Potential for Lower Commission Costs: Additional shares are purchased in large blocks, with brokerage commissions shared among all plan participants. There is no cost to enroll in the Plan.

• Convenience: After enrollment, the Plan is automatic and includes detailed statements for participants. Participants can terminate their enrollment at any time.

Pursuant to the Plan, unless a shareholder is ineligible or elects otherwise, all dividend and capital gains on common shares distributions are automatically reinvested by Computershare, as agent for shareholders in administering the Plan ("Plan Agent"), in additional common shares of the Fund. Shareholders who elect not to participate in the Plan will receive all dividends and distributions payable in cash paid by check mailed directly to the shareholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Plan Agent, as dividend paying agent. Shareholders may elect not to participate in the Plan and to receive all dividends and distributions in cash by sending written instructions to the Plan Agent, as dividend paying agent, at: Dividend Reinvestment Department, P.O. Box 43078, Providence RI 02940-3078. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by giving notice in writing to the Plan Agent; such termination will be effective with respect to a particular dividend or distribution if notice is received prior to the record date for the applicable distribution.

The shares are acquired by the Plan Agent for the participant's account either (i) through receipt of additional common shares from the Fund ("newly issued shares") or (ii) by purchase of outstanding common shares on the open market ("open-market purchases") on the NASDAQ or elsewhere. If, on the payment date, the net asset value per share of the common shares is equal to or less than the market price per common share plus estimated brokerage commissions (a "market premium"), the Plan Agent will receive newly issued shares from the Fund for each participant's account. The number of newly issued common shares to be credited to the participant's account will be determined by dividing the dollar amount of the dividend or distribution by the greater of (i) the net asset value per common share on the payment date, or (ii) 95% of the market price per common share on the payment date.

If, on the payment date, the net asset value per common share exceeds the market price plus estimated brokerage commissions (a "market discount"), the Plan Agent has a limited period of time to invest the dividend or distribution amount in shares acquired in open-market purchases. If, before the Plan Agent has completed its open-market purchases, the market price plus estimated brokerage commissions exceeds the net asset value of the common shares as of the payment date, the purchase price paid by Plan Agent may exceed the net asset value of the common shares, resulting in the acquisition of fewer common shares than if such dividend or distribution had been paid in common shares issued by the Fund. The weighted average price (including brokerage commissions) of all common shares purchased by the Plan Agent as Plan Agent will be the price per common share allocable to each participant. If the Plan Agent is unable to invest the full dividend amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will cease making open-market purchases and will invest the uninvested portion of the dividend or distribution amount in newly issued shares at the net asset value per common share at the close of business on the last purchase date.

The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends even though no cash is received by participants.

CALAMOS CLOSED-END FAMILY OF FUNDS SEMIANNUAL REPORT

Automatic Dividend Reinvestment Plan

There are no brokerage charges with respect to shares issued directly by the Fund as a result of dividends or distributions payable either in shares or in cash. However, 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, plus a $15 transaction fee. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants.

A participant may request the sale of all of the common shares held by the Plan Agent in his or her Plan account in order to terminate participation in the Plan. If such participant elects in advance of such termination to have the Plan Agent sell part or all of his shares, the Plan Agent is authorized to deduct from the proceeds a $15.00 fee plus the brokerage commissions incurred for the transaction. A participant may re-enroll in the Plan in limited circumstances.

The terms and conditions of the Plan may be amended by the Plan Agent or the Fund at any time upon notice as required by the Plan.

This discussion of the Plan is only summary, and is qualified in its entirety by the Terms and Conditions of the Dividend Reinvestment Plan filed as part of the Fund's registration statement.

For additional information about the Plan, please contact the Plan Agent, Computershare, at 866.226.8016. If you wish to participate in the Plan and your shares are held in your own name, simply call the Plan Agent. If your shares are not held in your name, please contact your brokerage firm, bank, or other nominee to request that they participate in the Plan on your behalf. If your brokerage firm, bank, or other nominee is unable to participate on your behalf, you may request that your shares be re-registered in your own name.

We're pleased to provide our shareholders with the additional benefit of the Fund's Dividend Reinvestment Plan and hope that it may serve your financial plan.

Additional Fund Information: Delaware Statutory Trust Act – Control Share Acquisitions

Each Fund is organized as a Delaware statutory trust and thus is subject to the control share acquisition statute contained in Subchapter III of the Delaware Statutory Trust Act (the DSTA Control Share Statute). The DSTA Control Share Statute applies to any closed-end investment company organized as a Delaware statutory trust and listed on a national securities exchange, such as the Fund. The DSTA Control Share Statute became automatically applicable to the Funds on August 1, 2022.

The DSTA Control Share Statute defines "control beneficial interests" (referred to as "control shares" herein) by reference to a series of voting power thresholds and provides that a holder of control shares acquired in a control share acquisition has no voting rights under the Delaware Statutory Trust Act (DSTA) or each Fund's Governing Documents (as used herein, "Governing Documents" means each Fund's Agreement and Declaration of Trust and By-Laws, together with any amendments or supplements thereto, including any Statement of Preferences establishing a series of preferred shares, as applicable) with respect to the control shares acquired in the control share acquisition, except to the extent approved by a Fund's shareholders by the affirmative vote of two—thirds of all the votes entitled to be cast on the matter, excluding all interested shares (generally, shares held by the acquiring person and their associates and shares held by Fund insiders).

The DSTA Control Share Statute provides for a series of voting power thresholds above which shares are considered control shares. Whether one of these thresholds of voting power is met is determined by

www.calamos.com
163

Additional Fund Information: Delaware Statutory Trust Act – Control Share Acquisitions

aggregating the holdings of the acquiring person as well as those of his, her or its "associates." These thresholds are:

• 10% or more, but less than 15% of all voting power;

• 15% or more, but less than 20% of all voting power;

• 20% or more, but less than 25% of all voting power;

• 25% or more, but less than 30% of all voting power;

• 30% or more, but less than a majority of all voting power; or

• a majority or more of all voting power.

Under the DSTA Control Share Statute, once a threshold is reached, an acquirer has no voting rights with respect to shares in excess of that threshold (i.e., the "control shares") until approved by a vote of shareholders, as described above, or otherwise exempted by the Funds' Board of Trustees. The DSTA Control Share Statute contains a statutory process for an acquiring person to request a shareholder meeting for the purpose of considering the voting rights to be accorded control shares. An acquiring person must repeat this process at each threshold level.

Under the DSTA Control Share Statute, an acquiring person's "associates" are broadly defined to include, among others, relatives of the acquiring person, anyone in a control relationship with the acquiring person, any investment fund or other collective investment vehicle that has the same investment adviser as the acquiring person, any investment adviser of an acquiring person that is an investment fund or other collective investment vehicle and any other person acting or intending to act jointly or in concert with the acquiring person.

Voting power under the DSTA Control Share Statute is the power (whether such power is direct or indirect or through any contract, arrangement, understanding, relationship or otherwise) to directly or indirectly exercise or direct the exercise of the voting power of shares of a Fund in the election of each Fund's Trustees (either generally or with respect to any subset, series or class of trustees, including any Trustees elected solely by a particular series or class of shares, such as the preferred shares). Thus, a Fund's preferred shares, as applicable, acquired in excess of the above thresholds would be considered control shares with respect to the preferred share class vote for two Trustees.

Any control shares of the Fund acquired before August 1, 2022 are not subject to the DSTA Control Share Statute; however, any further acquisitions on or after August 1, 2022 are considered control shares subject to the DSTA Control Share Statute.

The DSTA Control Share Statute requires shareholders to disclose to a Fund any control share acquisition within 10 days of such acquisition, and also permits the Fund to require a shareholder or an associate of such person to disclose the number of shares owned or with respect to which such person or an associate thereof can directly or indirectly exercise voting power. Further, the DSTA Control Share Statute requires a shareholder or an associate of such person to provide to the Fund within 10 days of receiving a request therefor from the Fund any information that the Fund's Trustees reasonably believe is necessary or desirable to determine whether a control share acquisition has occurred.

The DSTA Control Share Statute permits the Funds' Board of Trustees, through a provision in each Fund's Governing Documents or by Board action alone, to eliminate the application of the DSTA Control Share Statute to the acquisition of control shares in the Fund specifically, generally, or generally by types, as to specifically identified or unidentified existing or future beneficial owners or their affiliates or associates or as to any series or classes of shares. The DSTA Control Share Statute does not provide that the Fund can generally "opt out" of the application of the DSTA Control Share Statute; rather, specific acquisitions or classes of acquisitions may be exempted by the Board of Trustees, either in advance or retroactively, but other aspects of the DSTA Control Share Statute, which are summarized above, would continue to apply.

CALAMOS CLOSED-END FAMILY OF FUNDS SEMIANNUAL REPORT
164

Additional Fund Information: Delaware Statutory Trust Act – Control Share Acquisitions

The DSTA Control Share Statute further provides that the Board of Trustees is under no obligation to grant any such exemptions.

The foregoing is only a summary of the material terms of the DSTA Control Share Statute. Shareholders should consult their own counsel with respect to the application of the DSTA Control Share Statute to any particular circumstance.
