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 expected that any matter other than the proposal discussed in the proxy statement will be raised at the meeting.

JOINT PROXY STATEMENT

 

JOINT ANNUAL MEETING OF SHAREHOLDERS
June 22, 2007

 

This joint proxy statement is being sent to you by the board of trustees of each of Calamos Convertible Opportunities and Income Fund (“CHI”), Calamos Convertible and High Income Fund (“CHY”), Calamos Strategic Total Return Fund (“CSQ”) and Calamos Global Total Return Fund (“CGO”). The board of each Fund is asking you to complete and return the enclosed proxy card(s), permitting your shares of the Fund to be voted at the joint meeting of shareholders called to be held on June 22, 2007. Shareholders of record at the close of business on May 11, 2007 (the “record date”) are entitled to vote at the meeting. You are entitled to one vote for each share you hold, with a fraction of a vote for each fraction of a share. This joint proxy statement and enclosed proxy are first being mailed to shareholders on or about May 29, 2007. Each Fund’s board has determined that the use of this joint proxy statement for each annual meeting is in the best interest of each Fund and its shareholders in light of the matters being considered and voted on by the shareholders.

 

You should have received your Fund’s annual report to shareholders for the fiscal year ended October 31, 2006. If you would like another copy of the annual report, please write to or call the Fund at the address or telephone number shown at the top of this page. The report will be sent to you without charge.

 

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 and the Calamos family. As of March 31, 2007, Calamos Advisors managed approximately $42.6 billion in assets of individuals and institutions. The Funds and Calamos Advisors may be contacted at the same address, noted above.

 

ELECTION OF TRUSTEES

 

One trustee is to be elected to the board of each Fund by the holders of preferred shares of that Fund. The nominee is Stephen B. Timbers, who is currently a trustee who represents the preferred shares of each Fund and who was nominated by the board of trustees of that Fund.

 

The persons named on the accompanying proxy card(s) intend to vote at the meeting (unless otherwise directed) FOR the election of the nominee as trustee of each Fund. 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 term of Stephen B. Timbers will expire at the annual meeting of shareholders in 2007. The terms of John P. Calamos, Weston W. Marsh and William R. Rybak will expire at the annual meeting of shareholders in 2008 and the terms of Joe F. Hanauer, John E. Neal and David D. Tripple will expire at the annual meeting of shareholders in 2009. Messrs. Rybak and Timbers are the trustees who represent the holders of preferred shares. Nick P. Calamos resigned from the board of trustees effective June 28, 2006.

 

The holders of preferred shares of each Fund will have equal voting rights (i.e., one vote per share). Stephen B. Timbers has been nominated for election as a trustee to represent the holders of the preferred shares of each Fund. The vote of a plurality of the preferred shares of a Fund, voting as a separate class, is required to elect a representative of the preferred shares as a trustee of that Fund.

 

The trustee elected at the meeting will hold office until the 2010 annual meeting or until his successor is duly elected and qualified. If the 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.

 

The following table sets forth information on Mr. Timbers and each of the other current trustees.

 

Nominee for election at the meeting who is not an interested person of any Fund:

 

 

Continuing trustees who are interested persons of any Fund:

 

 

 

Continuing trustees who are not interested persons of any Fund:

 

 

 

The address of each of the trustees is 2020 Calamos Court, Naperville, Illinois 60563-2787.

 

Officers. John P. Calamos, Sr. is president of each Fund. The preceding table gives more information about Mr. Calamos. The following table sets forth each other officer’s name, position with the Funds, age, principal occupation during the past five years, and the date on which he first became an officer of the Funds. Each officer serves until his successor is chosen and qualified or until his resignation or removal by the board of trustees.

 

 

The address of each officer is 2020 Calamos Court, Naperville, Illinois 60563-2787.

 

Committees of the Board of Trustees. Each Fund’s board of trustees currently has six standing committees:

 

Executive Committee. Messrs. Calamos and Timbers are members of each executive committee, 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, Rybak, Timbers and Tripple serve on each audit committee. 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 New York Stock Exchange. 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, Timbers and Tripple serve on each governance committee. Each committee member is “independent” as defined by the New York Stock Exchange. The governance committees operate under a written charter adopted and approved by the 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 mutual fund 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.

 

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 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.

 

Dividend Committee. Mr. Calamos serves as the sole member of each dividend committee. Each dividend committee is authorized to declare distributions on the respective Fund’s shares in accordance with such 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 serve on each valuation committee. The valuation committees operate under a written charter approved by the board. The valuation committees oversee valuation matters of the Funds delegated to the pricing committee, 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 of the Funds and respond to other matters deemed appropriate by the 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 held for each Fund during the fiscal year ended October 31, 2006:

 

 

 

With the exception of Nick Calamos, all of the trustees and committee members then serving attended at least 75% of the meetings of the board of trustees and applicable committees held during the fiscal year ended October 31, 2006.

 

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

 

Effective November 1, 2006, compensation of the non-interested trustees of the Funds in the Fund Complex for their services as such consists of an aggregate annual retainer per trustee of $80,000, 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 receives a meeting attendance fee of $6,000 for any board meeting attended in person, $3,000 for any board meeting attended by telephone and $3,000 for any committee meeting attended in person or by telephone. 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, 2006 to each of the current trustees.

 

 

 

 

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. The deferred compensation payable to the participating trustee is credited to the participating trustee’s deferral account as of the business day such compensation would have been paid to the participating trustee. The value of a participating trustee’s deferred compensation account at any time is equal to what would be the value 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 participating 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 participating 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 participating trustee’s beneficiaries.

 

Certain Relationships and Related Transactions. Each Fund has entered into an Investment Management Agreement and a Financial Accounting Services Agreement with Calamos Advisors. Calamos Advisors is indirectly owned by John P. Calamos, Sr. According to the terms of the Investment Management Agreements, Calamos Advisors provides portfolio management services to the Funds in consideration for fees based on each Fund’s average weekly managed assets. According to the terms of the Financial Accounting Services Agreement, Calamos Advisors 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 to represent the holders of the 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. For the election of the trustee, one-third of the preferred shares of a Fund entitled to vote constitutes a quorum for that Fund.

 

Board Recommendation

 

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

 

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. 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.

 

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.

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. One-third of the preferred shares of each Fund entitled to vote present in person or represented by proxy constitutes a quorum for electing a trustee for the preferred shareholders of that Fund. 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 or postponements of the meeting to permit further solicitation of proxies. Any proposal for adjournment or postponement 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 all Section 16(a) forms they file. Based on a review of those forms furnished to the Funds, the Funds believe that their trustees and officers, investment adviser and affiliated persons of the investment adviser have complied with all applicable Section 16(a) filing requirements during the last fiscal year. 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 the matters required to be discussed 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 committees discussed with representatives of the independent auditors 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 board 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, William R. Rybak, Stephen B. Timbers and David D. Tripple.

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 pre-approved by the audit committees.

 

Aggregate Non-Audit Fees. D&T billed CHI, CHY, CSQ and CGO aggregate fees in the amounts of $3,876, $4,579, $9,296 and $1,649, respectively, for the fiscal year ended October 31, 2006 and $40,392, $47,008, $106,698 and $2,000, respectively, for the fiscal year ended October 31, 2005 for 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 amounts of $0 and $31,256 for the fiscal years ended October 31, 2006 and October 31, 2005, respectively, for services rendered.

 

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.

 

ADMINISTRATORS

 

Each Fund has entered into an administration agreement with State Street Bank and Trust Company, whose principal business address is One Lincoln Street, Boston, Massachusetts 02111.

 

SHAREHOLDER COMMUNICATIONS

 

Shareholders are able to send communications to the Funds’ governance committees. Communications should be addressed to the Secretary of the Funds at their principal offices at 2020 Calamos Court, Naperville, Illinois 60563-2787. The Secretary will forward any communications received directly to the governance committees. The Funds do not have a policy with regard to trustee attendance at annual meetings. With the exception of Joe F. Hanauer, all of the current trustees of the Funds attended the 2006 annual meeting.

 

SHAREHOLDER PROPOSALS

 

A shareholder proposal for consideration at the 2008 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. Such proposal must be received by the Secretary of the Fund not later than January 28, 2008. 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 April 14, 2008. 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.

 

By Order of the Board of Trustees of each Fund,
