The nominees for the board of each Fund are John P. Calamos, Sr. and Christopher M. Toub. The nominees are currently trustees of each Fund.

One trustee is to be elected to the board of each Fund for a one- year term by the holders of the common shares and preferred shares in the case of each Fund other than CPZ, voting together as a single class, and by the holders of the common shares in the case of CPZ, voting as a single class.

For each Fund other than CPZ, preferred shareholders are entitled, as a class, to the exclusion of the holders of all other classes of shares of a Fund, to elect two trustees of the Fund to serve a three-year term (regardless of the total number of trustees serving on the Board). These trustees are up for election in 2020 and 2022, respectively. One of these trustees, William R. Rybak, is a nominee to be considered at the Meeting. The nominee is currently a trustee of each Fund.

Stuckey will expire at the annual meeting

of shareholders in 2020. The term of John E. Neal will expire at the annual meeting of shareholders in 2021. The terms of Virginia G. Breen and Lloyd A.

If elected at the meeting to serve on the board of each Fund, John P. Calamos, Sr., Christopher M. Toub, and William R. Rybak will hold office for a three-year term beginning June 29, 2020 until the 2023 annual meeting or until his successor is duly elected and qualified.

The audit committees operate under a written charter adopted and approved by each board, a copy of which is available on the Funds’ website, www.calamos.com. The audit committees select independent auditors, approve services to be rendered by the auditors, monitor the auditors’ performance, review the results of each Fund’s audit, determine whether to recommend to the board that the Fund’s audited financial statements be included in the Fund’s annual report and respond to other matters deemed appropriate by the boards. Each committee member is “independent” as defined by the NASDAQ Listing Rules and is not an interested person of the Fund as defined in the 1940 Act. The board of each Fund has determined that each member of its audit committee is financially literate and that at least one of its members has prior accounting or related financial management experience. Messrs. Neal, Rybak, and Toub, and Mses. Breen and Stuckey have been determined by the board to be audit committee financial experts for each Fund.

Governance Committee. Messrs. Neal, Rybak, Toub, and Wennlund and Mses. Breen (Chair) and Stuckey serve on the governance committee of each board. Each committee member is “independent” as defined by the NASDAQ Listing Rules and is not an “interested person” of the Funds as defined in the 1940 Act. The governance committees operate under a written charter adopted by each board, a copy of which is available on the Funds’ website, www.calamos.com. The governance committees oversee the independence and effective functioning of the boards of trustees and endeavors to be informed about good practices for investment company boards. The committees also make recommendations to their respective boards regarding compensation of independent trustees.

The governance committees also function as nominating committees by making recommendations to the boards of trustees regarding candidates for election as non-interested trustees. The governance committees look to many sources for recommendations of qualified trustees, including current trustees, employees of Calamos Advisors, current shareholders of the Funds, search firms that are compensated for their services and other third-party sources. Any such firm identifies and evaluates potential candidates, conducts screening interviews and provides information to the governance committees with respect to the market for available candidates. In making trustee recommendations, the governance committees consider a number of factors, including a candidate’s background, integrity, knowledge and relevant experience. These factors are set forth in an appendix to the written committee charter. Any prospective candidate is interviewed by the Funds’ trustees and officers, and references are checked prior to initial nomination. The governance committees will consider shareholder recommendations regarding potential trustee candidates that are properly submitted to the governance committees for their consideration. Procedures for nominating a candidate are set forth in Appendix A to this proxy statement.

Valuation Committee. Messrs. Neal, Rybak, Toub, Wennlund (Chair) and Mses. Breen and Stuckey, serve on the valuation committee of each board. Each committee member is “independent” as defined by the NASDAQ Listing Rules and is not an “interested person” of the Funds as defined in the 1940 Act. The valuation committees operate under a written charter approved by each board. The valuation committees oversee valuation matters of each Fund delegated to the pricing committee (which is appointed and overseen by the board of trustees), including the fair valuation determinations and methodologies proposed and utilized by the pricing committee, review the Funds’ valuation procedures and their application by the pricing committee, review pricing errors and procedures for calculation of net asset value of each Fund and respond to other matters deemed appropriate by each board.

In addition to the above committees, each Fund’s board of trustees has appointed and oversees a pricing committee comprised of officers of the Fund and employees of Calamos Advisors.

The following table shows the number of meetings the board and standing committees of CHI, CHY, CSQ, CGO, CHW, CCD, and CPZ held during the fiscal year ended October 31, 2019:


	CHI		CHY		CSQ		CGO		CHW		CCD		CPZ

Valuation Committee		4		4		4		4		4		4		0

*	Although the Funds’ Dividend Committee held no meetings, the Dividend Committees acted by written consent on twelve occasions.

All of the trustees and committee members then serving attended at least 75% of the meetings of the board of trustees and applicable committees of each Fund held during the fiscal year ended October 31, 2019.

Leadership Structure and Qualifications of the Board of Trustees. Each Fund’s board of trustees is responsible for oversight of their respective Fund. Each Fund has engaged Calamos Advisors to manage that Fund on a day-to-day basis. Each board of trustees oversees Calamos Advisors and certain other principal service providers in the operations of their respective Fund.

Each board of trustees is currently composed of seven members, six of whom are non-interested trustees. If the nominees are elected at the meeting of shareholders, each board of trustees will continue to be composed of seven members, six of whom will be non-interested trustees. Each board of trustees meets in-person at regularly scheduled meetings four times throughout the year. In addition, each board of trustees may meet in-person or by telephone at special meetings or on an informal basis at other times. As described above, each board of trustees has established five standing committees — Audit, Dividend, Executive, Governance and Valuation — and may establish ad hoc committees or working groups from time-to-time, to assist each board of trustees in fulfilling its oversight responsibilities. The non-interested trustees also have engaged independent legal counsel to assist them in fulfilling their responsibilities. Such independent legal counsel also serves as counsel to each Fund.

The chairman of each board of trustees is an “interested person” of each Fund (as such term is defined in the 1940 Act). The non-interested trustees have appointed a lead independent trustee. The lead independent trustee serves as a liaison between Calamos Advisors and the non-interested trustees and leads the non-interested trustees in all aspects of their oversight of the Funds. Among other things, the lead independent trustee reviews and approves, with the chairman, the agenda for each board and committee meeting and facilitates communication among the Funds’ non-interested trustees. The trustees believe that each board of trustees’ leadership structure is appropriate given the characteristics and circumstances of the Funds. The trustees also believe that this structure facilitates the exercise of each board of trustees’ independent judgment in fulfilling its oversight function and efficiently allocates responsibility among committees.

Each board of trustees, including the independent trustees, has unanimously concluded that, based on each trustee’s and each nominee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other trustees and nominees, each continuing trustee should serve, and each nominee should be nominated to serve, as a member of each Board.

In making this determination, the board of trustees has taken into account the actual service of the current trustees during their tenure in concluding that each should continue to serve or be nominated to serve. The board of trustees also has considered each trustee’s and each nominee’s background and experience. Set forth below is a brief discussion of the specific experience qualifications, attributes or skills of each trustee and nominee that led each board of trustees to conclude that he or she should serve as a trustee.

Each of Ms. Breen and Messrs. Calamos, Neal, and Rybak has served for multiple years as a trustee of the Funds. In addition, each of Mses. Breen and Stuckey and Messrs. Calamos, Neal, Rybak, Toub, and Wennlund has more than 25 years of experience in the financial services industry. Each of Mses. Breen and Stuckey and Messrs. Calamos, Neal, Rybak, and Wennlund has experience serving on boards of other entities, including other investment companies. Each of Ms. Breen and Messrs. Calamos, Neal, Rybak and Toub has earned a Masters of Business Administration degree.

Risk Oversight. The operation of a registered investment company, including its investment activities, generally involves a variety of risks. As part of its oversight of the Funds, each board of trustees oversees risk through various regular board and committee activities. Each board of trustees, directly or through its committees, reviews reports from, among others, Calamos Advisors, the Funds’ Compliance Officer, the Funds’ independent registered public accounting firm, independent outside legal counsel, and internal auditors of

Calamos Advisors or its affiliates, as appropriate, regarding risks faced by the Funds and the risk management programs of Calamos Advisors and certain service providers. The actual day-to-day risk management with respect to the Funds resides with Calamos Advisors and other service providers to the Funds. Although the risk management policies of Calamos Advisors and the service providers are designed to be effective, there is no guarantee that they will anticipate or mitigate all risks. Not all risks that may affect the Funds can be identified, eliminated or mitigated and some risks simply may not be anticipated or may be beyond the control of the board of trustees or Calamos Advisors, its affiliates or other service providers.

Trustee Compensation. The Funds do not compensate any of the trustees who are interested persons of Calamos Advisors.

The compensation paid to the non-interested trustees of the Funds in the Fund Complex for their services as such consists of an annual retainer fee in the amount of $100,000, with annual supplemental retainers of $40,000 to the lead independent trustee, $20,000 to the chair of the audit committee and $10,000 to the chair of any other committee. Each non-interested trustee also receives a meeting attendance fee of $7,000 for any regular or special board meeting attended in person, $3,500 for any regular or special board meeting attended by telephone, $3,000 for any committee meeting attended in person or by telephone, and $1,500 per ad-hoc committee meeting to the ad-hoc committee chair. The following table sets forth information with respect to the compensation paid by the Funds and the Fund Complex during the fiscal year ended October 31, 2019 to each of the trustees then serving.

*	The Fund Complex includes Calamos Investment Trust, Calamos Advisors Trust, and the Funds.

**	Includes fees deferred during the year pursuant to the deferred compensation plan described below.

The Funds in the Fund Complex have adopted a deferred compensation plan for non-interested trustees (the “Plan”). Under the Plan, a trustee who is not an “interested person” of Calamos Advisors and has elected to participate in the Plan (“participating trustees”) may defer receipt of all or a portion of his or her compensation from the Funds in the Fund Complex in order to defer payment of income taxes or for other reasons. The deferred compensation payable to a participating trustee is credited to the trustee’s deferred compensation account as of the business day such compensation otherwise would have been paid to the trustee. The value of a trustee’s deferred compensation account at any time is equal to what the value would be if the amounts credited to the account had instead been invested in Class I shares of one or more of the funds of Calamos Investment Trust as designated by the trustee. Thus, 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. If a participating trustee retires, the trustee may elect to receive payments under the plan in a lump sum or in equal annual installments over a period of five years. If a participating trustee dies, any amount payable under the Plan will be paid to the trustee’s beneficiaries. Each Fund’s obligation to make payments under the Plan is a general obligation of that Fund. No Fund is liable for any other Fund’s obligations to make payments under the Plan. As of October 31, 2019, the value of the deferred compensation accounts for Mr. Neal was $1,931,728.

Certain Relationships and Related Transactions. Each Fund has entered into an Investment Management Agreement with Calamos Advisors. According to the terms of those agreements, Calamos Advisors provides portfolio management services to each Fund in consideration for fees based on the Fund’s managed assets.

Required Vote. The trustee of a Fund elected solely by the holders of preferred shares will be elected by the vote of a plurality of the preferred shares of the Fund present at the meeting, in person or by proxy. The trustee or trustees of a Fund elected by all preferred and common shareholders voting together will be elected by the vote of a plurality of all preferred and common shares of the Fund present at the meeting, in person or by proxy. Each share is entitled to one vote.

Board Recommendation

Each Fund’s board of trustees unanimously recommends that shareholders of each Fund vote “For” the nominees.

OTHER MATTERS

Each Fund’s board of trustees knows of no other matters that are intended to be brought before the meeting. If other matters are properly presented for action at the meeting, and the respective Fund did not have notice of the matter at least 45 days prior to the date on which proxy materials were first sent to shareholders, the proxyholders named in the enclosed form of proxy will vote on those matters in their sole discretion.

Unless a matter is specific to a particular class of shares, holders of the common shares and holders of the preferred shares of each Fund will vote together, as a single class, on any matter that may properly come before the meeting and at any adjournment or postponement thereof. It is not currently expected that any other matter will be raised at the meeting.

How Proxies Will Be Voted. All proxies solicited by the board of trustees that are properly executed and received prior to the meeting, and that are not revoked, will be voted at the meeting. Shares represented by those proxies will be voted as indicated on the proxy card or in accordance with the voting instructions received online or by telephone, or in the discretion of the proxyholders on any other matter that may properly come before the meeting.

How to Vote. Complete, sign and date the enclosed proxy card and return it in the enclosed envelope. Alternatively, call the toll-free number on the proxy card or access the internet address on the proxy card.

Expenses. The expenses of preparing, printing and mailing the enclosed proxy cards, the accompanying notice and this proxy statement and all other costs, in connection with the solicitation of proxies will be borne by the Funds. The Funds may also reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation material to the beneficial owners of shares of the Funds. In order to obtain the necessary quorum at the meeting, additional solicitation may be made by mail, telephone, telegraph, facsimile or personal interview by representatives of the Funds, Calamos Advisors, the Funds’ transfer agent, or by brokers or their representatives or by a solicitation firm that may be engaged by the Funds to assist in proxy solicitations. Any costs associated with such additional solicitation are not anticipated to be significant.

Householding. The Funds reduce the number of duplicate share- holder reports and proxy statements your household receives by sending only one copy of those documents to those addresses shared by two or more accounts. Call the Funds at 1-866-363-9219 or write to the Funds at the address on page one of this proxy statement to request individual copies of shareholder reports and proxy statements, or to request a single copy of shareholder reports and proxy statements if your household is receiving duplicate copies. We will begin sending your household single or multiple copies, as you request, as soon as practicable after receiving your request.

Revoking a Proxy. At any time before it has been voted, you may revoke your proxy by: (1) sending a letter saying that you are revoking your proxy to the Secretary of the Funds at the Funds’ offices located at 2020 Calamos Court, Naperville, Illinois 60563-2787; (2) properly executing and sending a later-dated proxy; or (3) attending the meeting, requesting return of any previously delivered proxy, and voting in person.

Quorum, Voting at the Meeting, and Adjournment. For any matter that may properly come before the meeting of a Fund, one-third of the shares entitled to vote on the matter constitutes a quorum for that matter. For purposes of determining the presence or absence of a quorum and for determining whether sufficient votes have been received for approval of any matter to be acted upon at the meeting, abstentions and broker nonvotes will be treated as shares that are present at the meeting but have not been voted. If a quorum is not present in person or by proxy at the meeting, or if a quorum is present at the meeting but not enough votes to approve a proposal are received, the persons named as proxyholders may propose one or more adjournments of the meeting to permit further solicitation of proxies. Any proposal for adjournment of the meeting for a Fund will require the vote of a majority of the shares of the Fund represented at the meeting in person or by proxy.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 30(h) of the 1940 Act and Section 16(a) of the Exchange Act require the Funds’ trustees and officers, investment adviser, affiliated persons of the investment adviser and persons who own more than 10% of a registered class of the Funds’ equity securities to file forms reporting their affiliation with the Fund(s) and reports of ownership and changes in ownership of the Funds’ shares with the Securities and Exchange Commission (the “SEC”). Those persons and entities are required by SEC regulation to furnish the Funds with copies of any Section 16(a) form they file. Based on a review of those forms furnished to the Funds, the Funds believe that their trustees and officers and investment adviser have complied with all applicable Section 16(a) filing requirements during the last fiscal year. Except as otherwise stated above, to the knowledge of each Fund’s management, no person owns beneficially more than 10% of a class of the Fund’s equity securities.

AUDIT COMMITTEE REPORT

The audit committee of each Fund’s board of trustees reviews that Fund’s annual financial statements with both management and the independent auditors, and the committee meets periodically with the independent and internal auditors to consider their evaluation of the Fund’s financial and internal controls.

Each audit committee, in discharging its duties, has met with and held discussions with management and the Fund’s independent and internal auditors. The committees have reviewed and discussed the audited financial statements with management. Management has represented to the independent auditors that each Fund’s financial statements were prepared in accordance with generally accepted accounting principles.

The audit committees have also discussed with the independent auditors various matters as required by Statement on Auditing Standards No. 61 (Communications with Audit Committees) and the independent auditors’ independence. The independent auditors provided to the committees the written disclosure required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and the representatives of the independent auditors confirmed to the committees their firm’s independence.

Based on each audit committee’s review and discussions with management and the independent auditors, the representations of management and the

reports of the independent auditors to the committees, each committee recommended that the respective Fund include the audited financial statements in the Fund’s annual report.

The members of the audit committee are: Virginia G. Breen, John E. Neal, William R. Rybak, Karen L. Stuckey, Christopher M. Toub, and Lloyd A. Wennlund.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committees of CHI, CHY, CSQ, CGO, CHW, and CCD selected Deloitte & Touche LLP (“D&T”) as the independent registered public accounting firm to audit the books and records of that Fund for its fiscal year ended October 31, 2019. CPZ had not yet launched as of October 31, 2019. It is not currently expected that a representative of D&T will be present at the meeting.

Audit Committee Pre-Approval Policies and Procedures. The charter of the audit committee of each Fund provides that the committee shall pre-approve the engagement of the Fund’s independent accountant to provide audit and non-audit services to the Fund and non-audit services to Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors that provides ongoing services to the Fund if the engagement relates directly to the operations or financial reporting of the Fund, including the fees and other compensation to be paid to the independent accountants, with certain exceptions. Under the charter, the committee may delegate pre- approval authority to a member of the committee, who must report any pre- approvals to the committee at its next meeting.

All services provided to each Fund described under the paragraphs entitled Audit-Related Fees, Tax Fees and All Other Fees were pre-approved in accordance with the audit committee charter. There were no services provided to Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors described in the paragraphs entitled Audit-Related Fees, Tax Fees and All Other Fees that were required to be pre-approved by the audit committees.

Aggregate Non-Audit Fees. D&T billed CHI, CHY, CSQ, CGO, CHW and CCD aggregate fees for non-audit services for the past two fiscal years in the following amounts:


Fund	Fiscal Year Ended October 31, 2019			Fiscal Year Ended October 31, 2018

CHY		$	0		$	0

CSQ		$	0		$	0

CGO		$	0		$	0

CHW		$	0		$	0

The Funds’ audit committees approved all such non-audit services.

D&T billed Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors aggregate non-audit fees in the amount of $33,250 for the fiscal year ended October 31, 2019 and $0 for the fiscal year ended October 31, 2018, for services rendered.

Each Fund’s audit committee has considered whether D&T’s provision of services (other than audit services to each Fund) to CAM, Calamos Advisors and affiliates of Calamos Advisors is compatible with maintaining D&T’s independence in performing audit services.

CUSTODIAN, FUND ACCOUNTING AGENT, AND ADMINISTRATOR

Each Fund has entered into agreements with State Street Bank and Trust Company, whose principal business address is 100 Huntington Avenue, Boston, Massachusetts 02116, to provide custodian, fund accounting and administrative services.

SHAREHOLDER COMMUNICATIONS

Shareholders are able to send communications to the Fund’s governance committee by mail addressed to the Secretary of the Fund at its principal office at 2020 Calamos Court, Naperville, Illinois 60563-2787. The Secretary will forward any communication received for the governance committee directly to the committee. The Funds do not have a policy with regard to trustee attendance at annual meetings. Five of the trustees of each Fund attended the 2019 annual meeting.

SHAREHOLDER PROPOSALS

A shareholder proposal for inclusion in the proxy for the 2021 annual meeting of a Fund should be submitted in writing pursuant to Rule 14a-8 of the Exchange Act to the Secretary of the Fund at 2020 Calamos Court, Naperville, Illinois 60563-2787. Any such proposal must be received by us at the address above by the close of business on January 19, 2021.

Shareholders who do not wish to submit a proposal for inclusion in the Funds’ combined proxy statements and form of proxy for the 2021 annual meeting in accordance with Rule 14a-8 may submit a proposal for consideration at the 2021 annual meeting in accordance with each Fund’s bylaws. Each Fund’s bylaws require that advance notice be given to the Fund in the event a shareholder wishes to propose nominations for election to the board of trustees or propose other business to be properly brought before an annual meeting.

The required notice must be in writing and received at the address listed above between January 19, 2021 and February 18, 2021. In order to be considered timely, such notice shall be delivered to the Fund’s Secretary at the principal executive office of the Funds listed above and shall set forth all information required under the Fund’s bylaws. Timely submission of a proposal does not mean the proposal will be included in the proxy material sent to shareholders.

Copies of a Fund’s bylaws are available on the EDGAR Database on the SEC’s Internet site at www.sec.gov. The Funds will also furnish, without charge, a copy of their bylaws to a shareholder upon request. Such requests should be directed to the Funds at 2020 Calamos Court, Naperville, Illinois 60563-2787 or by telephone at 1-866-363-9219.

Appendix A

Procedures for Shareholder Nomination of Trustee Candidate

A Fund shareholder who wishes to nominate a candidate to a Fund’s board of trustees must submit any such recommendation in writing via regular mail to the attention of the Fund’s Secretary, at the address of the Fund’s principal executive offices. The shareholder recommendation must include:

•

the number and class of all Fund shares owned beneficially and of record by the nominating shareholder at the time the recommendation is submitted and the dates on which such shares were acquired, specifying the number of shares owned beneficially;

•

a full listing of the proposed candidate’s education, experience (including knowledge of the investment company industry, experience as a director or senior officer of public or private companies, and directorships on other boards of other registered investment companies), current employment, date of birth, business and residence address, and the names and addresses of at least three professional references;

•

information as to whether the candidate is, has been or may be an “interested person” (as such term is defined in the 1940 Act) of the Funds, Calamos Advisors or any of its affiliates, and, if believed not to be or have been an “interested person,” information regarding the candidate that will be sufficient for the governance committee to make such determination;

•

the written and signed consent of the candidate to be named as a nominee and to serve as a trustee of the Funds, if elected;

•

a description of all arrangements or understandings between the nominating shareholder, the candidate and/or any other person or persons (including their names) pursuant to which the shareholder recommendation is being made, and if none, so specify;

•

the class or series and number of all shares of the Funds owned of record or beneficially by the candidate, as reported by the candidate; and

•

such other information that would be helpful to the governance committees in evaluating the candidate.

The governance committees may require the nominating shareholder to furnish other information they may reasonably require or deem necessary to

A-1

verify any information furnished pursuant to the procedures delineated above or to determine the qualifications and eligibility of the candidate proposed by the nominating shareholder to serve as a trustee. If the nominating shareholder fails to provide such additional information in writing within seven days of receipt of written request from the governance committees, the recommendation of such candidate as a nominee will be deemed not properly submitted for consideration, and the governance committees are not required to consider such candidate.

Unless otherwise specified by the governance committees’ chairman or by legal counsel to the non-interested trustees, the Funds’ Secretary will promptly forward all shareholder recommendations to the governance commit- tees’ chairman and the legal counsel to the non-interested trustees, indicating whether the shareholder recommendation has been properly submitted pursuant to the procedures adopted by the governance committees for the consideration of trustee candidates nominated by shareholders.

Recommendations for candidates as trustees will be evaluated, among other things, in light of whether the number of trustees is expected to change and whether the trustees expect any vacancies. During periods when the governance committees are not actively recruiting new trustees, shareholder recommendations will be kept on file until active recruitment is under way. After consideration of a shareholder recommendation, the governance commit- tees may dispose of the shareholder recommendation.
