PROXY STATEMENT

FOR THE ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON NOVEMBER 6, 2013

This proxy statement is furnished in connection with the solicitation by the Board of Trustees (the “Board” or “Board of Trustees”) of Managed Duration Investment Grade Municipal Fund (the “Fund”) of proxies to be used at the Annual Meeting of Shareholders (the “Meeting”) of the Fund to be held at the offices of Guggenheim Funds Distributors, LLC, 2455 Corporate West Drive, Lisle, Illinois 60532, on Wednesday, November 6, 2013, at 11:30 a.m. Central Time (and at any adjournment or postponements thereof) for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders. It is expected that the notice of annual meeting, proxy statement and the accompanying form of proxy are first being mailed to shareholders on or about October 8, 2013.

The close of business on September 27, 2013 has been fixed as the record date for the determination of shareholders entitled to notice of, and to vote at, the Meeting and any adjournment or postponement thereof. Each shareholder is entitled to one vote for each full share and an appropriate fraction of a vote for each fractional share held, with no shares having cumulative voting rights. On September 27, 2013, there were 6,800,476 shares of the Fund’s common shares (“Common Shares”) outstanding and 2,778 shares of the Fund’s auction market preferred shares (“Preferred Shares”) outstanding. These classes of stock are the only classes of stock currently authorized by the Fund.

In accordance with the Fund’s Third Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”), a quorum is constituted by the presence in person or by proxy of the holders of record of a majority of the Common Shares and Preferred Shares entitled to vote at the Meeting. However, a quorum for the election of Messrs. Ronald E. Toupin, Jr. and Ronald A. Nyberg, as discussed below, is constituted by the presence in person or by proxy of the holders of record of a majority of the Preferred Shares entitled to vote at the Meeting. In the event that a quorum is not present at the Meeting or, in the event that a quorum is present but sufficient votes have not been received to approve any Board proposal, the Meeting may be adjourned to permit further solicitation of proxies. The presiding officer or Trustee of the Fund for the Meeting or the

affirmative vote of a majority of the persons designated as proxies may adjourn the Meeting to permit further solicitation of proxies or for other reasons consistent with Delaware law and the Fund’s Declaration of Trust and Fourth Amended and Restated By-Laws. Unless otherwise instructed by a shareholder granting a proxy, the persons designated as proxies may use their discretionary authority to vote on questions of adjournment.

All properly executed proxies received prior to the Meeting will be voted at the Meeting in accordance with the instructions marked thereon or otherwise as provided therein. A signed proxy card or other authorization by a beneficial owner of Fund shares that does not specify how the beneficial owner’s shares should be voted on a proposal will be deemed an instruction to vote such shares in favor of the Proposal. Shareholders who execute proxies retain the right to revoke them in person at the Meeting or by written notice received by the Secretary of the Fund at any time before they are voted. Unrevoked proxies will be voted in accordance with the specifications thereon and, unless specified to the contrary, will be voted FOR the election of Trustees.

Broker non-votes (i.e., shares held by brokers or nominees, typically in “street name,” as to which proxies have been returned but instructions have not been received from the beneficial owners or persons entitled to vote, and the broker or nominee does not have discretionary voting power on a particular matter) will not be counted as shares present for quorum purposes with respect to such matters. Assuming the presence of a quorum, votes withheld and abstentions will have the same effect as votes against the Proposal and broker non-votes will have no effect on the vote on the Proposal.

Summary of Voting Rights on the Proposal

PROPOSAL 1: ELECTION OF TRUSTEES

At the Meeting, the preferred shareholders of the Fund (the “Preferred Shareholders”) will have equal voting rights (i.e., one vote per share) with the Fund’s common shareholders (the “Common Shareholders”) and, except as shown in the summary chart below, will vote together with Common Shareholders as a single class on all proposals to be brought before the Meeting. As summarized below, the election of Messrs. Barnes and Corso to the Board will require the affirmative vote of a majority of the votes of the Common Shareholders and the Preferred Shareholders, voting together as a single class, of the Fund cast for the election of Trustees at the Meeting in person or by proxy. The Preferred Shareholders, voting as a separate class, have the right to vote on the election of two Trustees, Messrs. Toupin 1 and Nyberg 2 . Common Shareholders will not

(1)

Mr. Toupin stood for re-election as a Class II Trustee at the 2012 annual meeting of shareholders. Quorum was not reached by the Preferred Shareholders, and Mr. Toupin continues to serve as a Trustee until such time as his successor is duly elected and qualified. Therefore, Mr. Toupin is standing for re-election at the Meeting. If re-elected, Mr. Toupin will serve for a term commensurate with the Class II Trustees, until the 2015 annual meeting of shareholders or until a successor shall have been elected and qualified.

(2)

Mr. Nyberg stood for re-election as a Class I Trustee at the 2011 and 2012 annual meetings of shareholders. Quorum was not reached by the Preferred Shareholders at either meeting, and Mr. Nyberg continues to serve as a Trustee until such time as his successor is duly elected and qualified. Therefore, Mr. Nyberg is standing for re-election at the Meeting. If re-elected, Mr. Nyberg will serve for a term commensurate with the Class I Trustees, until the 2014 annual meeting of shareholders or until a successor shall have been elected and qualified.

participate in the election of Messrs. Toupin and Nyberg. The election of Messrs. Toupin and Nyberg to the Board of Trustees will require the affirmative vote of a majority of the Preferred Shares (voting as a separate class) present and entitled to vote for the election of Trustee at the Meeting, in person or by proxy.


Shareholder Name	Common Shareholders	Preferred Shareholders
Randall C. Barnes	X	X
Clifford D. Corso	X	X
Ronald E. Toupin, Jr.	N/A	X
Ronald A. Nyberg	N/A	X

The Fund’s Board of Trustees is presently comprised of five (5) Trustees. The Board is divided into three classes, and members of each class hold office for a term of three years or until their successors are elected and qualified. The term of one class expires in each year.

The term of office of the Class III Trustees, if elected at this Meeting, expires at the annual meeting of shareholders to be held in 2016, or thereafter when their respective successors are duly elected. The term of office of the Class II Trustee, if elected at this Meeting, expires at the annual meeting of shareholders to be held in 2015, or thereafter when his respective successor is duly elected. The term of office of the Class I Trustee, if elected at this Meeting, expires at the annual meeting of shareholders to be held in 2014, or thereafter when his respective successor is duly elected.

On August 21, 2013, the Board recommended for election at the Meeting each Messrs. Barnes, Corso, Toupin, and Nyberg. At the Meeting, the persons named in the proxy intend to vote (unless directed not to vote) FOR the election of Messrs. Barnes and Corso as Class III Trustees, FOR the election of Mr. Toupin as a Class II Trustee, and FOR the election of Mr. Nyberg as a Class I Trustee. Messrs. Barnes, Corso, Toupin and Nyberg are currently members of the Board. Messrs. Barnes and Corso were last elected by shareholders in 2010, and Messrs. Toupin and Nyberg were last elected by shareholders in 2010 and 2008, respectively.

The nominees have agreed to serve if elected. There is no reason to believe that the nominees will become unavailable for election as Trustees of the Fund, but if that should occur before the Meeting, votes will be cast for the person(s) the Nominating and Governance Committee and the Board of Trustees recommend.

At the Annual Meeting of Shareholders held on November 11, 2004, the Fund’s shareholders elected the Board of Trustees to staggered terms in accordance with the Declaration of Trust. Accordingly, the term of office of only a single class of Trustees will expire in 2013. The effect of these staggered terms is to limit the ability of other entities or persons to acquire control of the Fund by delaying the replacement of a majority of the Board.

The principal executive offices of the Fund are located at 2455 Corporate West Drive, Lisle, Illinois 60532. Cutwater Investor Services Corp. (“CISC”), whose principal business address is 113 King Street, Armonk, New York 10504, is the Fund’s investment adviser. CISC is an indirect wholly-owned subsidiary of MBIA Inc., a Connecticut corporation and a New York Stock Exchange listed company with principal offices at 113 King Street, Armonk, New York 10504. The Fund’s servicing agent is Guggenheim Funds Distributors, LLC (“Guggenheim Distributors”) whose principal business address is 2455 Corporate West Drive, Lisle, Illinois 60532. The Fund’s administrator is Rydex Fund Services, LLC (“RFS” and together with Guggenheim Distributors, “Guggenheim Funds”), an affiliate of Guggenheim Distributors, whose principal business address is 805 King Farm Boulevard, Rockville, Maryland 20850. The Fund’s custodian, accounting agent and auction agent is The Bank of New York Mellon, whose principal business address is 101 Barclay Street, New York, New York 10286.

Qualifications and Experience of Trustees and Nominees

The Trustees and nominees were selected to serve and continue on the Board of Trustees, as applicable, based upon their skills, experience, judgment, analytical ability, diligence, ability to work effectively with other Trustees, availability and commitment to attend meetings and perform the responsibilities of a Trustee and a demonstrated willingness to take an independent and questioning view of management.

The following is a summary of the experience, qualifications, attributes and skills of each Trustee and nominee that support the conclusion, as of the date of this proxy statement, that each Trustee should serve as a Trustee in light of the Fund’s business and structure. References to the qualifications, attributes and skills of Trustees or nominees are pursuant to requirements of the SEC, do not constitute holding out of any Trustee or nominees as having any special expertise and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

Randall C. Barnes. Mr. Barnes has served as a Trustee of the Fund since 2006 and other funds in the Fund Complex since 2004. Through his service as a Trustee of the Fund and as chairman of the Audit Committee, his role with other funds, employment experience as President of Pizza Hut International and as Treasurer of PepsiCo, Inc., and his personal investment experience, Mr. Barnes is experienced in financial, accounting, regulatory and investment matters.

Each Trustee and nominee also has considerable familiarity with CISC and other service providers, and their operations, as well as the special regulatory requirements governing regulated investment companies and the special responsibilities of investment company trustees as a result of his substantial prior service as a Trustee of the Fund, as applicable.

Board’s Role in Risk Oversight

Consistent with its responsibility for oversight of the Fund, the Board, among other things, oversees risk management of the Fund’s investment program and business affairs directly and through the committee structure it has established. The Board has established the Audit Committee and the Nominating and Governance Committee to assist in its oversight functions, including its oversight of the risks the Fund faces. Each committee reports its activities to the Board on a regular basis. Risks to the Fund include, among others, investment risk, credit risk, liquidity risk, valuation risk and operational risk, as well as the overall business risk relating to the Fund. The Board has adopted, and periodically reviews, policies, procedures and controls designed to address these different types of risks. Under the Board’s supervision, the officers of the Fund, CISC and other service providers to the Fund, as applicable, also have implemented a variety of processes, procedures and controls to address various risks. In addition, as part of the Board’s periodic review of the Fund’s advisory and other service provider agreements, the Board may consider risk management aspects of the service providers’ operations and the functions for which they are responsible.

The Board requires officers of the Fund to report to the full Board on a variety of matters at regular and special meetings of the Board and its committees, as applicable, including matters relating to risk management. The Audit Committee also receives reports from the Fund’s independent registered public accounting firm on internal control and financial reporting matters. On at least a quarterly basis, the Board meets with the Fund’s Chief Compliance Officer, including separate meetings with the Independent Trustees in executive session, to discuss compliance

matters and, on at least an annual basis, receives a report from the Chief Compliance Officer regarding the effectiveness of the Fund’s compliance program. The Board, with the assistance of Fund management, reviews investment policies and risks in connection with its review of the Fund’s performance. In addition, the Board receives reports from CISC on the investments and securities trading of the Fund. With respect to valuation, the Board oversees a pricing committee comprised of CISC personnel and has approved Valuation and Pricing Procedures applicable to valuing the Fund’s securities, which the Board and its Audit Committee periodically review. The Board also requires CISC to report to the Board on other matters relating to risk management on a regular and as-needed basis.

Role of Diversity in Considering Board Candidates

In considering Trustee nominee candidates, the Nominating and Governance Committee takes into account a wide variety of factors, including the overall diversity of each Board’s composition. The Nominating and Governance Committee believes the Board generally benefits from diversity of background, experience and views among its members, and considers this a factor in evaluating the composition of the Board, but has not adopted any specific policy in this regard.

Trustees’ Prior Legal and Disciplinary Actions

The Trustees, including the nominees, have no prior legal or disciplinary actions.

Board Committees and Meetings

Board of Trustees and Meetings. The Board of Trustees is responsible for ensuring that the Fund is managed in the best interest of its shareholders. The Trustees oversee the Fund’s business by, among other things, meeting with the Fund’s management and evaluating the performance of the Fund’s service providers including CISC, Guggenheim Funds, the custodian, and the transfer agent. As part of this process, the Trustees consult with the Fund’s independent registered public accounting firm and with their independent legal counsel.

During the fiscal year ended July 31, 2013, the Board of Trustees met four times. Each Trustee attended at least 75% of the aggregate number of meetings of the Board and the committees for which he was eligible. The Fund does not have a written policy regarding attendance by Trustees at annual meetings of shareholders although Trustees are encouraged to attend annual meetings of shareholders.

The Board has an Audit Committee and a Nominating and Governance Committee that meet periodically during the year and whose responsibilities are described below.

Audit Committee. The Fund’s Audit Committee is currently composed of Messrs. Barnes, Nyberg and Toupin, all of whom have been determined not to be “interested persons” of the Fund, CISC or its affiliates, or Guggenheim Funds or its affiliates within the meaning of the 1940 Act, and who are “independent” as

defined in the NYSE listing standards. Mr. Barnes serves as the Chairman of the Audit Committee.

The Audit Committee is, among other things, responsible for: (i) overseeing the Fund’s accounting and financial reporting policies and practices, its internal controls over financial reporting and the quality, integrity and objectivity of the Fund’s financial statements and the independent audit thereof, (ii) approving prior to appointment the engagement of the Fund’s independent registered public accounting firm, (iii) selecting, overseeing and approving the compensation of the Fund’s independent registered public accounting firm, and (iv) discussing the Fund’s annual audited financial statements and semi-annual financial statements with management and the independent registered public accounting firm. The Audit Committee met three times during the fiscal year ended July 31, 2013.

The Audit Committee is governed by a written charter, the most recent version of which was approved by the Board on February 21, 2012 (the “Audit Committee Charter”). In accordance with proxy rules promulgated by the SEC, a fund’s audit committee charter is required to be filed at least once every three years (or when such charter is amended) as an exhibit to a fund’s proxy statement. The Fund’s amended Audit Committee Charter was attached as Appendix A to the Fund’s 2012 proxy statement.

Nominating and Governance Committee. The Nominating and Governance Committee, the principal functions of which are to select and nominate persons for election as Trustees of the Fund and to oversee certain corporate governance matters of the Fund, is currently composed of Messrs. Barnes, Nyberg and Toupin. Mr. Nyberg serves as the Chairman of the Nominating and Governance Committee. Only Trustees who are not “interested persons” of the Fund as defined in the 1940 Act and who are “independent” as defined in the NYSE listing standards are members of the Nominating and Governance Committee. The Nominating and Governance Committee may accept nominees recommended by the shareholders as it deems appropriate. Shareholders who wish to recommend a nominee should send nominations that include biographical data and set forth the qualifications of the proposed nominee to the Fund’s Secretary. The Nominating and Governance Committee met four times during the Fund’s fiscal year ended July 31, 2013.

The Nominating and Governance Committee is governed by a written charter, the most recent version of which was approved by the Board on October 20, 2008 (the “Nominating and Governance Committee Charter”). In accordance with proxy rules promulgated by the SEC, a fund’s nominating committee charter is required to be filed at least once every three years as an exhibit to a fund’s proxy statement. The Fund’s Nominating and Governance Committee Charter was attached as Appendix B to the Fund’s 2012 proxy statement.

The Nominating and Governance Committee identifies potential nominees through its network of contacts and may also engage, if it deems appropriate, a professional search firm. While the Nominating and Governance Committee meets

to discuss and consider such candidates’ qualifications and then chooses a candidate by majority vote, the Nominating and Governance Committee does not have specific, minimum qualifications for nominees and has not established specific qualities or skills that it regards as necessary for one or more of the Fund’s Trustees to possess (other than any qualities or skills that may be required by applicable law, regulation or listing standards). However, as set forth in the Nominating and Governance Committee Charter, the Nominating and Governance Committee may consider the following factors in evaluating a person as a potential nominee to serve as a Trustee of the Fund, among any others it may deem relevant:

·	whether or not the individual is an “interested person” as defined in the 1940 Act and whether the person is otherwise qualified under applicable laws and regulations to serve as a Trustee of the Fund;

·	whether or not the individual has any relationships that might impair his or her independence, such as any business, financial or family relationships with Fund management, the investment manager of the Fund, Fund service providers or their affiliates;

·	whether or not the individual serves on boards of, or is otherwise affiliated with, competing financial service organizations or their related mutual fund complexes;

·	whether or not the individual is willing to serve, and willing and able to commit the time necessary for the performance of the duties of a Trustee of the Fund;

·	the contribution the individual can make to the Board and the Fund, with consideration being given to the individual’s educational background and business and professional experience;

·	the character and integrity of the individual;

·	the overall diversity of the Board’s composition; and

·	the Nominating and Governance Committee may, but is not required to, retain a third party search firm at the Fund’s expense to assist in the identification of nominees who are not “interested persons” as defined in the 1940 Act (“Independent Trustee Nominees”).

Following an initial evaluation by the Committee, a nominee must:

be prepared to submit written answers to a questionnaire seeking professional and personal information that will assist the Committee to evaluate the candidate and to determine, among other matters, whether the candidate would be an Independent Trustee under the 1940 Act or otherwise have material relationships with key service providers to the Fund;

·	be prepared to submit character references and agree to appropriate background checks; and

·	be prepared to meet with one or more members of the Committee at a time and location convenient to those Committee members in order to discuss the nominee’s qualifications.

Additional Information

Report of the Audit Committee

After the meeting of the Audit Committee on September 25, 2013, the Audit Committee reported that it has: (i) reviewed and discussed the Fund’s audited financial statements with management; (ii) discussed with Ernst & Young LLP (“E&Y”), the independent registered public accounting firm to the Fund, the matters required to be discussed by Statement on Auditing Standards No. 61, such as the quality of the Fund’s accounting principles and internal controls; and (iii) previously received written confirmation from E&Y that it is independent along with written disclosures regarding such independence as required by Independence Standards Board Standard No. 1, and discussed the independent registered public accounting firm’s independence with E&Y.

The members of the Audit Committee are not professionally engaged in the practice of auditing or accounting and are not employed by the Fund for accounting, financial management or internal control. Moreover, the Audit Committee relies on and makes no independent verification of the facts presented to it or representations made by management or the independent registered public accounting firm. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles and policies, internal controls or procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not provide assurance that the audit of the Fund’s financial statements has been carried out in accordance with generally accepted

accounting standards or that the financial statements are presented in accordance with generally accepted accounting principles.

Based on the review and discussions referred to in items (i) through (iii) above, the Audit Committee recommended to the Board of Trustees (and the Board has approved) that the audited financial statements be included in the Fund’s annual report for the Fund’s fiscal year ended July 31, 2013. Additionally, the Audit Committee recommended that E&Y be appointed as the Fund’s independent registered public accounting firm for the fiscal year ending July 31, 2014.

The report of E&Y on the Fund’s financial statements for the fiscal years ended July 31, 2013 and July 31, 2012 contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles. There have been no disagreements with E&Y during the Fund’s fiscal years ended July 31, 2013 and July 31, 2012 or any subsequent interim period on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of E&Y, would have caused them to make reference thereto in their report on the financial statements for such year.

If requested by any shareholder, a representative of E&Y will be present via telephone at the Meeting to respond to appropriate questions from shareholders and will have an opportunity to make a statement if they choose to do so.

Audit Fees.

Audit Fees are fees related to the annual audit of the Fund’s financial statements and for services normally provided in connection with the statutory and regulatory filings of the Fund. For the fiscal year ended July 31, 2013, E&Y billed $28,000 to the Fund, including out of pocket expenses. For the fiscal year ended July 31, 2012 E&Y billed $24,650 to the Fund, including out-of-pocket expenses.

Audit-Related Fees

Audit-Related Fees are fees related to assurance and related services related to the annual audit of the Fund and for review of the Fund’s financial statements, other than the Audit Fees described above. These include agreed upon procedures reports performed for rating agencies and the issuance of comfort letters. Audit-Related Fees billed by E&Y to the Fund for the fiscal year ended July 31, 2013 were $4,000 and for the fiscal year ended July 31, 2012 were $4,000. E&Y did not bill any Audit-Related Fees to the Service Affiliates (as defined below) for audit related services related directly to the operations and financial reporting of the Fund for the Fund’s fiscal year ended July 31, 2013 or for the fiscal year ended July 31, 2012.

Tax Fees

Tax Fees are fees associated with tax compliance, tax advice and tax planning, including federal, state and local income tax return preparation and related advice and determination of taxable income and miscellaneous tax advice. Tax Fees billed by E&Y to the Fund for the fiscal year ended July 31, 2013 were $7,500 and for the fiscal year ended July 31, 2012 were $4,250. E&Y did not bill any Tax Fees to the Service Affiliates for tax services related directly to the operations and financial reporting of the Fund for the Fund’s fiscal year ended July 31, 2013 or July 31, 2012.

All Other Fees

All Other Fees are fees related to products and services other than those services reported above under “Audit Fees,” “Audit-Related Fees” and “Tax Fees.” There were no All Other Fees billed by E&Y to the Fund or the Service Affiliates for the fiscal year ended July 31, 2013 or for the fiscal year ended July 31, 2012.

Aggregate Non-Audit Fees

The Aggregate Non-Audit Fees billed by E&Y for services rendered to the Fund for the fiscal year ended July 31, 2013 were $11,500, consisting of $4,000 Audit-Related Fees and $7,500 Tax Fees. The Aggregate Non-Audit Fees billed by E&Y for services rendered to the Fund for the fiscal year ended July 31, 2012 were $8,250, consisting of $4,000 Audit-Related Fees and $4,250 Tax Fees. No Non-Audit Fees were billed by E&Y for services rendered to the Service Affiliates for the fiscal year ended July 31, 2013 or for the fiscal year ended July 31, 2012.

The Fund’s Audit Committee has adopted written policies relating to the pre-approval of the audit and non-audit services performed by the Fund’s independent registered public accounting firm. Unless a type of service to be provided by the independent registered public accounting firm has received general pre-approval, it requires specific pre-approval by the Audit Committee. Under the policies, on an annual basis, the Fund’s Audit Committee reviews and pre approves the services to be provided by the independent registered public accounting firm without having obtained specific pre-approval from the Audit Committee. The Audit Committee has delegated pre-approval authority to the Audit Committee Chairperson. In addition, the Audit Committee pre-approves any permitted non-audit services to be provided by the independent registered public accounting firm to CISC or any entity controlling, controlled by, or under common control with CISC (and such other entities, together, the “Service Affiliates”) if such services related directly to the operations and financial reporting of the Fund.

None of the services described above, provided in the fiscal year ended July 31, 2013 or the fiscal year ended July 31, 2012, were approved pursuant to the de minimis exception provided in Rule 2-01(c)(7)(i)(C) of Regulation S-X promulgated by the SEC.

The Audit Committee has considered whether the provision of non-audit services that were rendered by E&Y to CISC and Service Affiliates that were not pre-approved (not requiring pre approval) is compatible with maintaining E&Y’s independence, respectively. All services provided by E&Y to the Fund, CISC or service affiliates that were required to be pre-approved were pre-approved as required.

Section 16(a) Beneficial Ownership Reporting Compliance

Each Trustee and certain officers of the Fund, CISC, certain affiliated persons of CISC and persons who own beneficially more than 10% of any class of outstanding equity securities of the Fund are required to file forms reporting their affiliation with the Fund and reports of ownership and changes in ownership with

the SEC and the NYSE. These persons and entities are required by SEC regulation to furnish the Fund with copies of all such forms they file. Based solely on a review of those forms furnished to the Fund, the Fund believes that the Fund’s Trustees and relevant officers, CISC and relevant affiliated persons of CISC have complied with all applicable filing requirements during the fiscal year ended July 31, 2013.

Proposals to be Submitted by Shareholders and Other Shareholders and Other Shareholder Communications

All proposals by shareholders of the Fund that are intended to be presented at the Fund’s next annual meeting of shareholders to be held in 2014 must be received by the Fund no earlier than July 9, 2014 and no later than August 8, 2014. All proposals by shareholders of the Fund that are intended to be presented at the Fund’s next annual meeting of shareholders to be held in 2014 must be received by the Fund for inclusion in the Fund’s proxy statement and proxy relating to that meeting no later than June 5, 2014. The submission by a shareholder of a proposal for inclusion in the proxy materials does not guarantee that it will be included.

In order for proposals made outside of Rule 14a-8 under the Exchange Act to be considered “timely” within the meaning of Rule 14a 4(c) under the Exchange Act, such proposal must be received by the Fund no later than August 24, 2014.
