                                PROXY STATEMENT

     The accompanying proxy is solicited by the Board of Trustees of the Fund
for use at the annual meeting of shareholders of the Fund, to be held on May 15,
2006 at 11:30 a.m., Central time (the "Annual Meeting"), and at any adjournment
thereof. At the Annual Meeting, shareholders will be asked to consider the
election of Ronald E. Toupin, Jr. and Randolph L. Kohn to the Board of Trustees
of the Fund. This Proxy Statement and the form of proxy were first mailed to
shareholders on or about April 3, 2006.

     The Board of Trustees has fixed the close of business on March 17, 2006 as
the record date for the determination of shareholders entitled to notice of and
to vote at the Annual Meeting and any adjournment thereof. As of the close of
business on that date, the Fund had issued and outstanding 29,152,820 common
shares of beneficial interest, no par value ("Common Shares"), and 8,200
preferred shares of beneficial interest, no par value ("Preferred Shares" and,
together with the Common Shares, the "Shares"). The Common Shares and Preferred
Shares are the only classes of shares currently authorized by the Fund.

     Shareholders of the Fund as of the close of business on March 17, 2005 will
be entitled to one vote for each Share held, and a fractional vote with respect
to fractional Shares, with no cumulative voting rights. Holders of the Preferred
Shares ("Preferred Shareholders") and holders of Common Shares ("Common
Shareholders") will vote as a single class at the Annual Meeting on the election
of Randolph L. Kohn. Pursuant to the Investment Company Act of 1940, as amended
(the "1940 Act"), Preferred Shareholders, voting as a single class, will have
the right to elect two Trustees of the Fund. These Trustees are currently Ronald
A. Nyberg (whose term of office will expire at the 2008 annual meeting) and
Ronald E. Toupin, Jr., who will stand for re-election at the Annual Meeting. The
Preferred Shareholders, voting as a single class, have the right to vote on the
election of Mr. Toupin. Pursuant to the 1940 Act, the Common Shareholders do not
have the right to vote with respect to the election of Mr. Toupin. Common
Shareholders and Preferred Shareholders will vote as a single class on any other
matter properly brought before the Annual Meeting (except as otherwise required
by the Fund's Amended and Restated Agreement and Declaration of Trust (the
"Declaration of Trust") and Bylaws and applicable law). The

                                        1


table below summarizes the right of the Common Shareholders and Preferred
Shareholders to vote with respect to the matters to come before the Annual
Meeting.

Election of Randolph L. Kohn                                    X                      X
Election of Ronald E. Toupin, Jr.                                                      X


     Thirty percent (30%) of the total Shares of the Fund entitled to vote at
the Annual Meeting must be represented in person or by proxy to constitute a
quorum with respect to the election of Mr. Kohn. Thirty percent (30%) of the
Preferred Shares of the Fund entitled to vote at the Annual Meeting must be
represented in person or by proxy to constitute a quorum with respect to the
election of Mr. Toupin. Each shareholder has the right to revoke his or her
proxy at any time before it is voted. A proxy may be revoked by filing with the
Secretary of the Fund a written revocation or a properly executed proxy bearing
a later date or by voting in person at the Annual Meeting. Any shareholder may
attend the Annual Meeting, whether or not he or she has previously given a
proxy.

     Election of Mr. Kohn to the Board of Trustees of the Fund requires the
affirmative vote of a plurality of the Shares entitled to vote on the election
of Mr. Kohn and present in person or represented by proxy at the Annual Meeting.
Election of Mr. Toupin to the Board of Trustees of the Fund requires the
affirmative vote of a plurality of the Preferred Shares (voting as a separate
class) entitled to vote on the election of Mr. Toupin and present in person or
represented by proxy at the Annual Meeting.

     The solicitation of proxies for the Annual Meeting will be made primarily
by mail. However, if necessary to ensure satisfactory representation at the
Annual Meeting, additional solicitation may take place in writing or by
telephone or personal interview by officers of the Fund (or their designees),
who will not receive compensation from the Fund for such services. As the date
of the meeting approaches, if we have not received your proxies, you may receive
a telephone call from our proxy solicitor, Computershare Fund Services, Inc.
("CFS"), which has been retained to assist shareholders in the voting process.
For these services, the Fund will pay CFS a fee that is not expected to exceed
$2,000. However, the exact cost will depend on the amount and types of services
rendered. The Fund will reimburse brokers and other nominees, in accordance with
New York Stock Exchange approved reimbursement rates, for their expenses in
forwarding solicitation material to the beneficial owners of shares of the Fund.
All expenses incurred in connection with the solicitation of proxies, including
the services of CFS, will be borne by the Fund.

     Abstentions and "broker non-votes" (i.e., shares held by brokers or
nominees as to which (i) instructions have not been received from the beneficial
owners or the persons entitled to vote and (ii) the broker or nominee does not
have discretionary voting power on a particular matter) will be counted as
shares present for purposes of determining whether a quorum is present, but will
not be counted as

                                        2


having been voted on the matter in question. Assuming that a quorum would
otherwise be present, abstentions and broker non-votes will accordingly have no
effect for the purpose of determining whether a Trustee has been elected.

     Randolph L. Kohn, Gregory B. McShea, Nicholas Dalmaso and Melissa J.
Nguyen, the persons named as proxies on the proxy card accompanying this Proxy
Statement, were selected by the Board of Trustees to serve in such capacity.
Messrs. Kohn and McShea and Ms. Nguyen are each officers of the Fund, and
Messrs. Kohn and Dalmaso are Trustees of the Fund. Each executed and returned
proxy will be voted in accordance with the directions indicated thereon or, if
no direction is indicated, such proxy will be voted for the election as Trustees
of the Board of Trustees' nominees listed in this Proxy Statement. Discretionary
authority is provided in the proxy as to any matters not specifically referred
to therein. The Board of Trustees is not aware of any other matters which are
likely to be brought before the Annual Meeting. However, if any such matters
properly come before the Annual Meeting, the persons named in the proxy are
fully authorized to vote thereon in accordance with their judgment and
discretion. In matters other than the election of Trustees, except where a
different vote is required by any provision of law or the Fund's Declaration of
Trust or Bylaws, a plurality of a quorum of the Shares necessary for the
transaction of business at a shareholders' meeting shall decide any question.

                                    PROPOSAL

                         ELECTION OF CLASS III TRUSTEES

     In accordance with the Declaration of Trust, the Trustees were divided into
the following three classes (each a "Class") prior to the initial public
offering of the Common Shares: Class I, whose term will expire at the Fund's
2007 annual meeting of shareholders; Class II, whose term will expire at the
Fund's 2008 annual meeting of shareholders; and Class III, whose initial term
will expire at the Fund's Annual Meeting. At each annual meeting, successors to
the Class of Trustees whose term expires at that annual meeting shall be elected
for a three-year term.

     The following table sets forth the nominees who will stand for election at
the Annual Meeting, the Class of Trustees to which they have been designated and
the expiration of their terms if elected:



NOMINEE                                            CLASS     EXPIRATION OF TERM IF ELECTED*
-------                                          ---------   ------------------------------
                                                       
Randolph L. Kohn...............................  Class III        2009 Annual Meeting
Ronald E. Toupin, Jr. .........................  Class III        2009 Annual Meeting


---------------

* A Trustee shall hold office until the annual meeting for the year in which his
  or her term expires and until his or her successor shall be elected and shall
  qualify, subject, however, to prior death, resignation, retirement,
  disqualification or removal from office.

     Under the Fund's classified Board structure, ordinarily only those Trustees
in a single Class may be replaced in any one year, and it would require a
minimum of two years to change a majority of the Board of the Fund under normal
circumstances. This structure, which may be regarded as an "anti-takeover"
measure, may make it more difficult for the Fund's shareholders to change the
majority of Trustees of the Fund and, thus, promotes the continuity of
management.

     It is the intention of the persons designated as proxies in the proxy card,
unless otherwise directed therein, to vote at the Annual Meeting for the
election of Messrs. Kohn and Toupin. Each of the nominees has agreed to serve if
elected at the Annual Meeting. If either nominee is unable or unavailable to
serve, the persons named in the proxies will vote the proxies for such other
person as the Board of Trustees may recommend.

     Information Regarding the Trustees.  Information about the Trustees and
nominees is set forth below. The address of each Trustee and nominee is c/o the
Fund at its principal business address (385 East

                                        4


Colorado Boulevard, Pasadena, California 91101). Of the individuals listed
below, only Messrs. Kohn and Toupin are nominees for election at the Annual
Meeting.

     Audit Committee.  The Board of Trustees has established an Audit Committee
composed solely of Trustees who are not "interested persons" (as defined in the
1940 Act) of the Fund or the Investment Adviser, consisting of Messrs. Erichsen,
Larson, Nyberg and Toupin. Each member of the Audit Committee is "independent,"
as independence for audit committee members is defined in the currently
applicable listing standards of the New York Stock Exchange, on which the Common
Shares of the Fund are listed and traded. The Audit Committee provides oversight
with respect to the accounting and financial reporting policies and procedures
of the Fund and, among other things, considers the selection of the independent
registered public accounting firm for the Fund and the scope of the audit and
approves services proposed to be performed by the independent registered public
accounting firm on behalf of the Fund and, under certain circumstances, the
Investment Adviser and certain of its affiliates. The Trustees have adopted a
written charter for the Audit Committee, a copy of which was attached as
Appendix A to the Fund's proxy statement dated March 31, 2004.

     The Audit Committee of the Fund has submitted the following report:

     The Audit Committee has reviewed and discussed with management of the Fund
the audited financial statements for the last fiscal year. The Audit Committee
has discussed with the Fund's independent

                                        10


registered public accounting firm the matters required to be discussed by
Statements on Auditing Standards No. 61 ("SAS 61"). SAS 61 requires the
independent registered public accounting firm to communicate to the Audit
Committee matters including, if applicable: (1) methods used to account for
significant unusual transactions; (2) the effect of significant accounting
policies in controversial or emerging areas for which there is a lack of
authoritative guidance or consensus; (3) the process used by management in
formulating particularly sensitive accounting estimates and the basis for the
independent registered public accounting firm's conclusions regarding the
reasonableness of those estimates; and (4) disagreements with management over
the application of accounting principles and certain other matters. The Audit
Committee has received the written disclosures and the letter from the Fund's
independent registered public accounting firm required by Independence Standards
Board Standard No. 1 (requiring the independent registered public accounting
firm to make written disclosures to and discuss with the Audit Committee various
matters relating to the independent registered public accounting firm's
independence), and has discussed with such independent registered public
accounting firm the independence of such independent registered public
accounting firm. Based on the foregoing review and discussions, the Audit
Committee recommended to the Trustees the inclusion of the audited financial
statements for the last fiscal year in the Fund's annual report to shareholders.

                                          Ronald E. Toupin (Chairman)
                                          Peter C. Erichsen
                                          Michael Larson
                                          Ronald A. Nyberg

     Governance and Nominating Committee.  The Board of Trustees has established
a Governance and Nominating Committee composed solely of Trustees who are not
"interested persons" (as defined in the 1940 Act) of the Fund or the Investment
Adviser, consisting of Messrs. Erichsen, Larson, Nyberg (Chairman) and Toupin.
The Governance and Nominating Committee meets to select nominees for election as
Trustees of the Fund and consider other matters of Board policy. The Trustees
have adopted a written charter for the Governance and Nominating Committee, a
copy of which was included as Appendix B to the Fund's proxy statement dated
March 31, 2004. The Fund does not currently maintain a website on which the
charter is made available.

     The Governance and Nominating Committee requires that Trustee candidates
have a college degree or equivalent business experience, but has not otherwise
established specific, minimum qualifications that must be met by an individual
to be considered by the Committee for nomination as a Trustee. The Governance
and Nominating Committee may take into account a wide variety of factors in
considering Trustee candidates, including, but not limited to: (i) availability
and commitment of a candidate to attend meetings and perform his or her
responsibilities to the Board of Trustees, (ii) relevant industry and related
                                        11


experience, (iii) educational background, (iv) financial expertise, (v) an
assessment of the candidate's ability, judgment and expertise and (vi) overall
diversity of the Board's composition. The Governance and Nominating Committee
may consider candidates for Trustee recommended by the Fund's current Trustees,
officers, Investment Adviser, shareholders or any other source deemed to be
appropriate by the Governance and Nominating Committee. Candidates properly
submitted by shareholders (as described below) will be considered and evaluated
on the same basis as candidates recommended by other sources.

     The policy of the Governance and Nominating Committee is to consider
nominees recommended by shareholders to serve as Trustee, provided that any such
recommendation is submitted in writing to the Fund, to the attention of the
Secretary, at the address of the principal executive offices of the Fund, not
less than one hundred and twenty calendar days nor more than one hundred and
thirty-five calendar days prior to the date of the meeting at which the nominee
would be elected and that such shareholder recommendation contains the
information about such nominee required by the Fund's procedures for
shareholders to submit nominee candidates, which are a part of the Governance
and Nominating Committee's Charter. The Governance and Nominating Committee has
full discretion to reject nominees recommended by shareholders, and there is no
assurance that any such person so recommended and considered by the Governance
and Nominating Committee will be nominated for election to the Fund's Board of
Trustees.

     Meetings.  During 2005, the Board of Trustees held six meetings, the Audit
Committee held five meetings and the Governance and Nominating Committee held
two meetings. Each Trustee attended at least 75% of the aggregate of the total
number of meetings of the Board of Trustees and the Committees of the Board of
Trustees on which he served. The Fund's policies require the Trustees to attend
the Fund's annual shareholder meetings. Each Trustee except Mr. Kohn attended
the Fund's annual shareholder meeting in May 2005.

     Shareholder Communications.  The Board of Trustees provides a process for
shareholders to send communications to the Board of Trustees. Shareholders may
mail written communications to the attention of the Board of Trustees, care of
the Fund's Secretary, at the Fund's shareholder servicing agent, Claymore
Securities, Inc., 2455 Corporate West Drive, Lisle, Illinois 60532. The written
communication must include the shareholder's name, be signed by the shareholder,
refer to the Fund, and include the class and number of shares held by the
shareholder as of a recent date.

     Trustee Compensation.  Trustees of the Fund who are affiliated persons of
the Fund, the Investment Adviser, or Claymore Securities, Inc. receive no salary
or fees from the Fund. Each other Trustee of the Fund receives a fee of $15,000
annually for serving as a Trustee of the Fund, and a fee of $1,000 and related
expenses for each meeting of the Board of Trustees attended. The Chairman of the
Board of Trustees receives an additional $2,000 per year for serving in that
capacity. The Audit Committee Chairman and the Governance and Nominating
Committee Chairman each receive an additional $1,500 annually for serving
                                        12


in their respective capacities. Members of the Audit Committee and the
Governance and Nominating Committee receive $500 for each committee meeting
attended.

     For the fiscal year ended December 31, 2005, the Trustees received the
compensation set forth in the following table for serving as Trustees of the
Fund and as Trustees of the other fund in the same "Fund Complex."

                                SHARE OWNERSHIP

     As of the close of business on March 1, 2006, no person owned of record or,
to the knowledge of the Fund, owned beneficially more than five percent (5%) of
the outstanding Shares of either class, except that Cascade Investment, L.L.C.
and William H. Gates III (as the sole member of Cascade Investment, L.L.C.)
owned beneficially 2,030,400 Common Shares (representing approximately 6.9% of
the outstanding Common Shares) and Cede & Co., as nominee for participants in
The Depository Trust Company, held of record 29,131,454 Common Shares
(representing approximately 99.9% of the outstanding Common Shares) and all
8,200 outstanding Preferred Shares. Cascade Investment, L.L.C.'s address is 2365
Carillon Point, Kirkland, Washington 98033. Mr. Gates's address is One Microsoft
Way, Redmond, Washington 98052. Cede & Co.'s address is 55 Water Street, 25th
Floor, New York, New York 10041-0001. Mr. Larson is the Business Manager of
Cascade Investment, L.L.C. and has voting and investment power with respect to
the Common Shares held by Cascade Investment, L.L.C, but disclaims any
beneficial ownership of the Common Shares beneficially owned by Cascade
Investment, L.L.C. and Mr. Gates. As of March 1, 2006, all Trustees, nominees
for Trustee and officers of the Fund as a group beneficially owned less than 1%
of the outstanding Common Shares or Preferred Shares of the Fund on such date.

            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, as amended (the "Exchange Act"), require the Fund's officers and
Trustees, the Investment Adviser, certain affiliates of the Investment Adviser,
and persons who beneficially own more than ten percent of a registered class of
the Fund's equity securities, among others, to file reports of ownership and
changes in ownership with the Securities and Exchange Commission ("SEC") and the
New York Stock Exchange. These persons are required by SEC regulation to furnish
the Fund with copies of all Section 16(a) forms they file.

     Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons, the Fund believes that,
during 2005, all such filing requirements were met.

                         ANNUAL REPORT TO SHAREHOLDERS

     The Fund's Annual Report to Shareholders for the fiscal year ended December
31, 2005 contains financial and other information pertaining to the Fund. The
Fund will furnish without charge to each person whose proxy is being solicited,
upon request of such person, a copy of the Annual Report to Shareholders.

                 INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

     The Audit Committee of the Board of Trustees has selected
PricewaterhouseCoopers LLP as the independent registered public accounting firm
of the Fund for the fiscal year ending December 31, 2006, and the Board of
Trustees, including a majority of the Trustees who are not "interested persons"
(as defined in the 1940 Act) of the Fund, has unanimously ratified such
selection. PricewaterhouseCoopers LLP's service is subject to termination by a
majority of the outstanding Shares of the Fund. Representatives of
PricewaterhouseCoopers LLP are not currently expected to attend the Annual
Meeting.

     The following table presents fees billed in each of the Fund's last two
fiscal years for services rendered to the Fund by PricewaterhouseCoopers LLP:



FISCAL YEAR ENDED    AUDIT FEES   AUDIT-RELATED FEES   TAX FEES   ALL OTHER FEES
-----------------    ----------   ------------------   --------   --------------
                                                      
December 31,
  2004............    $25,100           $6,400          $  900          $0
December 31,
  2005............    $27,200           $6,500          $1,050          $0


     "Audit Fees" represents fees billed for each of the last two fiscal years
for professional services rendered for the audit of the Fund's financial
statements for those fiscal years and services that are normally provided by the
accountant in connection with statutory or regulatory filings or engagements for
that fiscal year.

     "Audit Related Fees" represents fees billed for each of the last two fiscal
years for assurance and related services reasonably related to the performance
of the audit of the Fund's annual financial statements for those years,
including a review of rating agency compliance testing for the Fund's Preferred
Shares.

     "Tax Fees" represents fees billed for each of the last two fiscal years for
professional services related to tax compliance, tax advice and tax planning,
including preparation of federal and state income tax returns and preparation of
excise tax returns.

     "All Other Fees" represents fees, if any, billed for other products and
services rendered by PricewaterhouseCoopers LLP to the Fund for the last two
fiscal years.

     For the Fund's fiscal years ended December 31, 2004 and December 31, 2005,
PricewaterhouseCoopers LLP billed aggregate non-audit fees in the amounts of
$372,631 and $202,047, respectively, to the Fund, the Investment Adviser and any
entity controlling, controlled by or under common control with the Investment
Adviser that provides ongoing services to the Fund.

     Pre-Approval Policies of the Audit Committee.  The Audit Committee has
determined that all work performed for the Fund by PricewaterhouseCoopers LLP
will be pre-approved by the full Audit Committee

                                        19


and, therefore, has not adopted pre-approval procedures. Since the Fund's
inception in July 2003, all audit and non-audit services performed by
PricewaterhouseCoopers LLP for the Fund, and all non-audit services performed by
PricewaterhouseCoopers LLP for the Investment Adviser and any entity
controlling, controlled by or under common control with the Investment Adviser
that provides ongoing services to the Fund (a "Service Affiliate"), to the
extent that such services related directly to the operations and financial
reporting of the Fund, have been pre-approved by the Audit Committee. No
"Audit-Related Fees," "Tax-Fees" and "Other Fees" set forth in the table above
were waived pursuant to paragraph (c)(7)(i)(c) of Rule 2-01 of Regulation S-X.
PricewaterhouseCoopers LLP did not bill fees for non-audit services that
required pre-approval by the Audit Committee pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X during the Fund's fiscal year ended December 31,
2004. PricewaterhouseCoopers LLP billed "Audit-Related Fees" in the amount of
$127,460 for non-audit services (a SAS 70 audit to review and test operating
effectiveness of controls placed in operation for the Investment Adviser) that
required pre-approval by the Audit Committee pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X during the Fund's fiscal year ended December 31,
2005. PricewaterhouseCoopers LLP did not bill any "Tax Fees" or "All Other Fees"
that required pre-approval by the Audit Committee pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X during the Fund's fiscal year ended
December 31, 2005.

     The Audit Committee has considered whether the provision of the non-audit
services rendered by PricewaterhouseCoopers LLP since the Fund's inception to
the Investment Adviser and any Service Affiliate that were not required to be
pre-approved by the Audit Committee pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X is compatible with maintaining the independence of
PricewaterhouseCoopers LLP.

                                  ADJOURNMENT

     In the absence of a quorum at the Annual Meeting, or (even if a quorum is
present) if sufficient votes in favor of a proposal set forth in the Notice of
Annual Meeting are not received by the time scheduled for the Annual Meeting,
the persons named as proxies may propose one or more adjournments of the Annual
Meeting after the date set for the original Annual Meeting, with no other notice
than announcement at the Annual Meeting, to permit further solicitation of
proxies with respect to such proposal. In addition, if, in the judgment of the
persons named as proxies, it is advisable to defer action on a proposal, the
persons named as proxies may propose one or more adjournments of the Annual
Meeting with respect to such proposal for a reasonable time. Any adjournments
with respect to a proposal will require the affirmative vote of a plurality of
the Shares of the Fund entitled to vote thereon present in person or represented
by proxy at the session of the Annual Meeting to be adjourned. The persons named
as proxies will vote in favor of such adjournment those proxies which they are
entitled to vote in favor of the proposal in question. They
                                        20


will vote against any such adjournment those proxies required to be voted
against such proposal. The costs of any additional solicitation and of any
adjourned session will be borne by the Fund. Any proposals for which sufficient
favorable votes have been received by the time of the Annual Meeting may be
acted upon and, if so, such action will be final regardless of whether the
Annual Meeting is adjourned to permit additional solicitation with respect to
any other proposal.

                                 OTHER BUSINESS

     The Fund is not aware of any other matters to be presented for action at
the Annual Meeting. However, if any such other matters are properly presented,
it is the intention of the persons designated in the enclosed proxy to vote in
accordance with their best judgment.

                                          By Order of the Board of Trustees
