Calamos Advisors LLC, each Fund’s investment adviser, is referred to as “Calamos Advisors.” Calamos Advisors is an indirect subsidiary of Calamos Asset Management, Inc. (“CAM”), a publicly traded corporation whose voting shares are majority-owned by John P. Calamos, Sr. and the Calamos family. As of March 31, 2008, Calamos Advisors managed approximately $40.9 billion in assets of individuals and institutions. The Funds and Calamos Advisors may be contacted at the same address, noted above.


 

ELECTION OF TRUSTEES
 
Two trustees are to be elected to the board of each Fund for a three-year term and one trustee is to be elected to the board of each Fund, other than CHW, for a two-year term. The nominees for the board of each Fund are John P. Calamos, Sr. and William R. Rybak, and the nominee for the board of each Fund other than CHW is Weston W. Marsh. Each nominee is currently a trustee of each Fund.
 
Unless otherwise directed, the persons named on the accompanying proxy card(s) intend to vote at the meeting FOR the election of each nominee as described above. Currently, there are seven trustees. In accordance with each Fund’s Agreement and Declaration of Trust, its board of trustees is divided into three classes of approximately equal size. The terms of the trustees of the different classes are staggered. The current terms of John P. Calamos, Sr. and William R. Rybak will expire at the annual meeting of shareholders in 2008. The term of Weston W. Marsh with respect to CHW will expire at the annual meeting of shareholders in 2010, while the current term of Mr. Marsh with respect to each other Fund will expire at the annual meeting of shareholders in 2008. The terms of Joe F. Hanauer, John E. Neal and David D. Tripple will expire at the annual meeting of shareholders in 2009, and the term of Stephen B. Timbers will expire at the annual meeting of shareholders in 2010. Messrs. Rybak and Timbers are the trustees who are elected solely by the holders of the preferred shares.
 
The holders of preferred shares of each Fund will have equal voting rights with the holders of common shares (i.e., one vote per share). William R. Rybak has been nominated for election as a trustee by the holders of the preferred shares of each Fund. The vote of a plurality of the preferred shares of each Fund is required to elect such trustee. John P. Calamos, Sr. and Weston W. Marsh have been nominated for election as trustees by all shareholders. The vote of a plurality of the preferred shares and the common shares of each Fund, voting together as a single class, is required to elect those trustees.
 
The two trustees elected at the meeting to serve on the board of each Fund for a three-year term will hold office until the 2011 annual meeting or until his successor is duly elected and qualified. The one trustee elected at the meeting to serve on the board of each Fund other than CHW for a two-year term will hold office until the 2010 annual meeting or until his successor is duly elected and qualified. If a nominee is unable to serve because of an event not now anticipated, the persons named as proxyholders may vote for another person designated by the board of trustees.

Committees of the Board of Trustees. Each Fund’s board of trustees currently has five standing committees:
 
Executive Committee. Messrs. Calamos and Timbers are members of the executive committee of each board, which has authority during intervals between meetings of the board of trustees to exercise the powers of the board, with certain exceptions.
 
Audit Committee. Messrs. Hanauer, Marsh, Neal (Chair), Rybak, Timbers and Tripple serve on the audit committee of each board. The audit committees operate under a written charter adopted and approved by each


6


 

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 New York Stock Exchange. 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, Timbers and Tripple have been determined by the board to be audit committee financial experts for each Fund.
 
Governance Committee. Messrs. Hanauer, Marsh, Neal, Rybak (Chair), Timbers and Tripple serve on the governance committee of each board. Each committee member is “independent” as defined by the New York Stock Exchange 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 board of trustees and endeavor to be informed about good practices for investment company boards.
 
The governance committees also function as nominating committees by making recommendations to the board 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. Search firms that are retained by the governance committees to identify potential candidates evaluate potential candidates, conduct screening interviews and provide 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 charter. Any prospective candidate is interviewed by the Funds’ trustees and officers, and references are checked. The governance committees will consider shareholder recommendations regarding potential candidates for nomination as trustees properly submitted to the governance committees for their consideration. Procedures for nominating a candidate are set forth in Appendix A to this proxy statement.

Dividend Committee. Mr. Calamos serves as the sole member of the dividend committee of each board. Each dividend committee is authorized to declare distributions on the respective Fund’s shares in accordance with the Fund’s distribution policies, including, but not limited to, regular dividends, special dividends and short- and long-term capital gains distributions.
 
Valuation Committee. Messrs. Marsh, Timbers and Tripple (Chair), serve on the valuation committee of each board. The valuation committees operate under a written charter approved by each board. The valuation committees review matters related to the valuation of securities held by the Funds pursuant to the Funds’ procedures for valuation of portfolio securities.
 
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 of each Fund held during the fiscal year ended October 31, 2007:

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 (the “Plan”). Under the Plan, a trustee who is not an “interested person” of Calamos Advisors who has elected to participate in the Plan (“participating trustees”) may defer receipt of all or a portion of his compensation from the Funds in the Fund Complex. Compensation deferred for a participating trustee is credited to the trustee’s deferral account as of the business day on which that compensation otherwise would have been paid to the trustee. The value of a trustee’s deferral 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 any distributions on those 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 designated beneficiaries. As of October 31, 2007, the values of the deferred compensation accounts of Messrs. Marsh and Neal were $410,378 and $649,111, respectively.
 
Certain Relationships and Related Transactions. Each Fund has entered into an Investment Management Agreement and a Financial Accounting Services Agreement with Calamos Advisors. According to the terms of those agreements, Calamos Advisors provides portfolio management services


9


 

to each Fund in consideration for fees based on the Fund’s managed assets and provides certain accounting services to each Fund in consideration for fees based on the Fund’s daily average net 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 shareholders will be elected by the vote of a plurality of all 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, 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.

To each Fund’s knowledge, no change in control of such Fund has occurred since the beginning of its last fiscal year.
 
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 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.
 
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 shareholder 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 1-800-582-6959 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


16


 

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 Securities Exchange Act of 1934 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”) and the New York Stock Exchange. 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 that: (i) with respect to CHW, the initial statement of beneficial ownership of securities on Form 3 was filed late by Calamos Advisors, John P. Calamos, Sr., Nick P. Calamos, Patrick H. Dudasik, James S. Hamman, Jr., Nimish S. Bhatt, Mark J. Mickey, Weston W. Marsh, Joe F. Hanauer, John E. Neal, William R. Rybak, Stephen B. Timbers and David D. Tripple; and (ii) with respect to twelve transactions in shares of CHW and two transactions in shares of CGO, the reports on Form 4 were filed late by John P. Calamos, Sr. 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


17


 

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). 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: Joe F. Hanauer, Weston W. Marsh, John E. Neal, Chair, William R. Rybak, Stephen B. Timbers and David D. Tripple.
 
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
Each Fund’s audit committee 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 ending October 31, 2008. 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


19


 

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 in 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.

The Funds’ audit committees approved all such non-audit services.
 
Each Fund’s audit committee has considered whether D&T’s provision of services (other than audit services to each Fund) to the Fund, Calamos Advisors and affiliates of Calamos Advisors that provide services to the Fund is compatible with maintaining D&T’s independence in performing audit services.

All of the trustees of each Fund except John P. Calamos, Sr. attended the 2007 annual meeting.
 
SHAREHOLDER PROPOSALS
 
A shareholder proposal for consideration at the 2009 annual meeting of a Fund should be submitted in writing pursuant to Rule 14a-8 of the Securities Exchange Act of 1934 to the Secretary of the Fund at 2020 Calamos Court, Naperville, Illinois 60563-2787.

A shareholder wishing to provide notice in the manner prescribed by Rule 14a-4(c)(1) of a proposal submitted outside of the process of Rule 14a-8 must submit such written notice to the Fund not later than March 28, 2009. Any proposal shall be included in a written notice that includes the shareholder’s name and address, the number of shares of the Fund(s) that the shareholder owns of record or beneficially, the dates on which those shares were acquired, and documentary support for a claim of beneficial ownership if the shares are registered in a different name. Timely submission of a proposal does not mean the proposal will be included in the proxy material sent to shareholders.

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 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 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 committees’ 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 committees may dispose of the shareholder recommendation.
