In addition, the Board has nominated Scott E. Eston for election as a Class II Trustee and Harriett Tee Taggart as a Class III Trustee. Mr. Eston and Ms. Taggart were appointed by the Board as Class II and Class III Trustees, respectively, effective September 1, 2011.Class II Trustees chosen to succeed the Trustees whose terms are expiring and Mr. Eston will be elected for a three-year term and Ms. Taggart will be elected to serve until 2013 to coincide with the term of office of her Class.  An effect of staggered terms is to limit the ability of entities or persons to acquire control of the Fund.

Proxy Statement dated August 24, 2012


Interested Trustee

Mr. Faust is an “interested person” (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)) by reason of his affiliation with EVM, the Fund’s investment adviser, and EVC, a publicly-held holding company, which owns all the outstanding shares of EVM and of EVM’s trustee, EV.  (EVM, EVC, and their affiliates are sometimes referred to collectively as the “Eaton Vance Organization”.)  Mr. Faust holds positions with other Eaton Vance affiliates that are comparable to his position with Eaton Vance listed above.

Election of Trustees by APS and Common Shares

Under the terms of the Fund’s By-Laws, as amended (the “By-Laws”), the holders of the APS are entitled as a class, to the exclusion of the holders of the Common Shares, to elect two Trustees of the Fund.  Simply stated, the APS Trustees are only elected by the holders of the Fund’s APS.  Holders of Common Shares do not vote on the election of APS Trustees.Mr. Verni has been nominated for election by the holders of the APS.  The By-Laws further provide for the election of the nominees named above by the holders of the Common Shares and the APS, voting as a single class.  Election of Trustees is non-cumulative.  Shareholders do not have appraisal rights in connection with the proposal in this proxy statement.  The Trustees of the Fund shall be elected by the affirmative vote of a plurality of the shares of the Fund entitled to vote.

Board Meetings and Committees

The Board of Trustees has general oversight responsibility with respect to the business and affairs of the Fund. The Board has engaged an investment adviser and (if applicable) a sub-adviser (collectively the “adviser”) to manage the Fund and is responsible for overseeing such adviser and other service providers to the Fund. The Board is currently composed of ten Trustees, including nine Trustees who are not “interested persons” of the Fund, as that term is defined in the 1940 Act (each a “noninterested Trustee”). In addition to eight regularly scheduled meetings per year, the Board holds special meetings or informal conference calls to discuss specific matters that may require action prior to the next regular meeting. As discussed below, the Board has established five committees to assist the Board in performing its oversight responsibilities.

The Board has appointed a noninterested Trustee to serve in the role of Chairman. The Chairman’s primary role is to participate in the preparation of the agenda for meetings of the Board and the identification of information to be presented to the Board with respect to matters to be acted upon by the Board. The Chairman also presides at all meetings of the Board and acts as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chairman may perform such other functions as may be requested by the Board from time to time. Except for any duties specified herein or pursuant to the Fund’s Declaration of Trust or By-laws, the designation of Chairman does not impose on such noninterested Trustee any duties, obligations or liability that is greater than the duties, obligations or liability imposed on such person as a member of the Board, generally.

The Fund is subject to a number of risks, including, among others, investment, compliance, operational, and valuation risks. Risk oversight is part of the Board’s general oversight of the Fund and is addressed as part of various activities of the Board of Trustees and its Committees. As part of its oversight of the Fund, the Board directly, or through a Committee, relies on and reviews reports from, among others, Fund management, the adviser, the principal underwriter, the Chief Compliance Officer (the “CCO”), and other Fund service providers responsible for day-to-day oversight of Fund investments, operations and compliance to assist the Board in identifying and understanding the nature and extent of risks and determining whether, and to what extent, such risks can be mitigated. The Board also interacts with the CCO and with senior personnel of the adviser, the principal underwriter and other Fund service providers and provides input on risk management issues during meetings of the Board and its Committees.  Each of the adviser, the principal underwriter and the other Fund service providers has its own independent interest and responsibilities in risk management, and its policies and methods for carrying out risk management functions will depend, in part, on its individual priorities, resources and controls. It is not possible to identify all of the risks that may affect the Fund or to develop processes and controls to eliminate or mitigate their occurrence or effects.  Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve the Fund’s goals.

The Board, with the assistance of management and with input from the Board’s various committees, reviews investment policies and risks in connection with its review of Fund performance. The Board has appointed a Fund CCO who oversees the implementation and testing of the Fund compliance program and reports to the Board regarding compliance matters for the Fund and its principal service providers. In addition, as part of the Board’s periodic review of the advisory, subadvisory (if applicable), distribution and other service provider agreements, the Board may consider risk management aspects of their operations and the functions for which they are responsible. With respect to valuation, the Board approves and periodically reviews valuation policies and procedures applicable to valuing the Fund’s shares. The adviser is responsible for the implementation and day-to-day administration of these valuation policies and procedures and provides reports periodically to the Board regarding these and related matters. In addition, the Board or the Audit Committee of the Board receives reports periodically from the independent public accounting firm for the Fund regarding tests performed by such firm on the valuation of all securities, as well as with respect to other risks associated with mutual funds. Reports received from service providers, legal counsel and the independent public accounting firm assist the Board in performing its oversight function.

Proxy Statement dated August 24, 2012


The Fund’s Declaration of Trust does not set forth any specific qualifications to serve as a Trustee.  The Charter of the Governance Committee also does not set forth any specific qualifications, but does set forth certain factors that the Committee may take into account in considering noninterested Trustee candidates.  In general, no one factor is decisive in the selection of an individual to join the Board. Among the factors the Board considers when concluding that an individual should serve on the Board are the following: (i) knowledge in matters relating to the mutual fund industry; (ii) experience as a director or senior officer of public companies; (iii) educational background; (iv) reputation for high ethical standards and professional integrity; (v) specific financial, technical or other expertise, and the extent to which such expertise would complement the Board of Trustees’ existing mix of skills, core competencies and qualifications; (vi) perceived ability to contribute to the ongoing functions of the Board of Trustees, including the  ability and commitment to attend meetings regularly and work collaboratively with other members of the Board of Trustees; (vii) the ability to qualify as a noninterested Trustee for purposes of the 1940 Act and any other actual or potential conflicts of interest involving the individual and the Fund; and (viii) such other factors as the Board determines to be relevant in light of the existing composition of the Board of Trustees.  

Among the attributes or skills common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the other Trustees, management, sub-advisers, other service providers, counsel and independent registered public accounting firms, and to exercise effective and independent business judgment in the performance of their duties as Trustees.  Each Trustee’s ability to perform his or her duties effectively has been attained through the Trustee’s business, consulting, public service and/or academic positions and through experience from service as a Board member in the Eaton Vance Group of Funds (and/or in other capacities, including for any predecessor funds), public companies, or non-profit entities or other organizations as set forth below.  Each Trustee’s ability to perform his or her duties effectively also has been enhanced by his or her educational background, professional training, and/or other life experiences.

In respect of each current Trustee, the individual’s substantial professional accomplishments and experience, including in fields related to the operations of the Eaton Vance Group of Funds, were a significant factor in the determination that the individual should serve as a Trustee.  The following is a summary of each Trustee’s particular professional experience and additional considerations that contributed to the Board’s conclusion that he or she should serve as a Trustee:

Scott E. Eston. Mr. Eston has served as a Trustee in the Eaton Vance Group of Funds since 2011. He currently serves on the investment and advisory board of the BAC Seed Fund, a real estate investment firm.  From 1997 through 2009, Mr. Eston served in several capacities at Grantham, Mayo, Van Otterloo and Co. (“GMO”), including as Chairman of the Executive Committee and Chief Operating and Chief Financial Officer, and also as the President and Principal Executive officer of GMO Trust, an affiliated open-end registered investment company. From 1978 through 1997, Mr. Eston was employed at Coopers & Lybrand L.L.P. (now PricewaterhouseCoopers) (since 1987 as a Partner).

Benjamin C. Esty.  Mr. Esty has served as a Trustee in the Eaton Vance Group of Funds since 2005 and is the Chairperson of the Portfolio Management Committee.  He is the Roy and Elizabeth Simmons Professor of Business Administration and Finance Unit Head at the Harvard University Graduate School of Business Administration.

Faust Jr.  Mr. Faust has served as a Trustee in the Eaton Vance Group of Funds since 2007.  He is currently Chairman, Chief Executive Officer and President of EVC, Director and President of EV, Chief Executive Officer and President of Eaton Vance and BMR, and Director of EVD.  Mr. Faust previously served as an equity analyst, portfolio manager, Director of Equity Research and Management and Chief Investment Officer of Eaton Vance (1985-2007).  He holds B.S. degrees in Mechanical Engineering and Economics from the Massachusetts Institute of Technology and an MBA from Harvard Business School.  Mr. Faust has been a Chartered Financial Analyst since 1988.

Allen R. Freedman.  Mr. Freedman has served as a Trustee in the Eaton Vance Group of Funds since 2007.  Mr. Freedman also serves as a Director of Stonemor Partners L.P. where he also serves as the Chair of the Audit Committee and a member of the Trust and Compliance Committee.  Mr. Freedman was previously a Director of Assurant, Inc. from 1979-2011, a Director of Systems & Computer Technology Corp. from 1983-2004 and Chairman from 2002-2004, a Director of Loring Ward International from 2005-2007 and Chairman and a Director of Indus International, Inc. from 2005-2007.  Mr. Freedman was formerly the Chairman and Chief Executive Officer of Fortis, Inc.

leading the audit; and (vi) prepare, as necessary, such Audit Committee reports consistent with the requirements of applicable Securities and Exchange Commission (“SEC”) and stock exchange rules for inclusion in the proxy statement for the Annual Meeting of Shareholders of the Fund.  The Fund’s Board of Trustees has adopted a written charter for its Audit Committee, a copy of which is attached as Exhibit A.  The written charter is also available on the Eaton Vance website, www.eatonvance.com, by selecting “Individual Investors” followed by “Resources” and then “Fund Corporate Governance”.  The Audit Committee’s Report is set forth below under “Additional Information”.  

Messrs. Verni (Chair), Esty, Freedman, Park and Pearlman, and Mmes. Peters and Taggart are members of the Contract Review Committee.  The purposes of the Contract Review Committee are to consider, evaluate and make recommendations to the Board of Trustees concerning the following matters: (i) contractual arrangements with each service provider to the Fund, including advisory, sub-advisory, transfer agency, custodial and fund accounting, distribution services (if any) and administrative services; (ii) any and all other matters in which any of the Fund’s service providers (including Eaton Vance or any affiliated entity thereof) has an actual or potential conflict of interest with the interests of the Fund or its shareholders; and (iii) any other matter appropriate for review by the noninterested Trustees, unless the matter is within the responsibilities of other Committees or the Board of Trustees.  

Messrs. Esty (Chair) and Freedman, and Mmes. Peters and Taggart are currently members of the Portfolio Management Committee. The purposes of the Portfolio Management Committee are to: (i) assist the Board of Trustees in its oversight of the portfolio management process employed by the Fund and its investment adviser and sub-adviser(s), if applicable, relative to the Fund’s stated objective(s), strategies and restrictions; (ii) assist the Board of Trustees in its oversight of the trading policies and procedures and risk management techniques applicable to the Fund; and (iii) assist the Board of Trustees in its monitoring of the performance results of all funds, giving special attention to the performance of certain funds that it or the Board of Trustees identifies from time to time.

Messrs. Pearlman (Chair) and Eston, and Ms. Stout are currently members of the Compliance Reports and Regulatory Matters Committee. The purposes of the Compliance Reports and Regulatory Matters Committee are to: (i) assist the Board of Trustees in its oversight role with respect to compliance issues and certain other regulatory matters affecting the Fund; (ii) serve as a liaison between the Board of Trustees and the Fund’s CCO; and (iii) serve as a “qualified legal compliance committee” within the rules promulgated by the SEC.

Mmes. Stout (Chair), Peters and Taggart, and Messrs. Eston, Esty, Freedman, Park, Pearlman and Verni are members of the Governance Committee.  Each Governance Committee member is independent under applicable listing standards of the New York Stock Exchange.  The purpose of the Governance Committee is to consider, evaluate and make recommendations to the Board of Trustees with respect to the structure, membership and operation of the Board of Trustees and the Committees thereof, including the nomination and selection of noninterested Trustees and a Chairperson of the Board and the compensation of such persons.

The Fund’s Board of Trustees has adopted a written charter for its Governance Committee, a copy of which is available on the Eaton Vance website, www.eatonvance.com, by selecting “Individual Investors” followed by “Resources” and then “Fund Corporate Governance”.  The Governance Committee identifies candidates by obtaining referrals from such sources as it deems appropriate, which may include current Trustees, management of the Fund, counsel and other advisors to the Trustees, and shareholders of the Fund who submit recommendations in accordance with the procedures described in the Committee’s charter.  In no event shall the Governance Committee consider as a candidate to fill any vacancy an individual recommended by management of the Fund, unless the Governance Committee has invited management to make such a recommendation.  The Governance Committee will, when a vacancy exists or is anticipated, consider any nominee for noninterested Trustee recommended by a shareholder if such recommendation is submitted in writing to the Governance Committee, contains sufficient background information concerning the candidate, including evidence the candidate is willing to serve as a noninterested Trustee if selected for the position, and is received in a sufficiently timely manner. The Governance Committee’s procedures for identifying and evaluating candidates for the position of noninterested Trustee, including the procedures to be followed by shareholders of the Fund wishing to recommend such candidates for consideration by the Governance Committee and the qualifications the Governance Committee will consider, are set forth in an appendix to the Committee’s charter.

The Governance Committee does not have a formal policy to consider diversity when identifying candidates for the position of noninterested Trustee.  Rather, as a matter of practice, the Committee considers the overall diversity of the Board’s composition when identifying candidates.  Specifically, the Committee considers how a particular candidate could be expected to contribute to overall diversity in the backgrounds, skills and experiences of the Board’s members and thereby enhance the effectiveness of the Board.  In addition, as part of its annual self-evaluation, the Board has an opportunity to consider the diversity of its members, including specifically whether the Board’s members have the right mix of characteristics, experiences and skills.  The results of the self-evaluation are considered by the Governance Committee in its decision-making process with respect to candidates for the position of noninterested Trustee.

Remuneration of Trustees

Each noninterested Trustee is compensated for his or her services according to a fee schedule adopted by the Board of Trustees, and receives a fee that consists of an annual retainer and a committee service component.  The Fund currently pays each noninterested Trustee a pro rata share, as described below of:  (i) an annual retainer of $195,000; (ii) an additional annual retainer of $120,000 for serving as the Chair of the noninterested Trustees; (iii) an additional annual retainer of $45,000 for Committee Service; (iv) an additional annual retainer of $20,000 for serving as the Governance Committee Chair, the Audit Committee Chair, the Compliance Committee Chair or the Portfolio Management Committee Chair; (v) the Chairperson of an Ad Hoc Committee will receive $5,000; and (vi) out-of-pocket expenses.  The pro rata share paid by the Fund is based on the Fund’s average net assets as a percentage of the average net assets of all the funds in the Eaton Vance Fund Complex.  For the fiscal year ended June 30, 2012, the Trustees of the Fund earned the compensation set forth below in their capacities as Trustees of the Fund.  For the calendar year ended December 31, 2011, the Trustees earned the compensation set forth below in their capacities as Trustees of the funds in the Eaton Vance Fund Complex(1):

As of August 10, 2012, the Eaton Vance Fund Complex consisted of 182 registered investment companies or series thereof.  The compensation schedule disclosed above reflects the current compensation schedule, but may not have been in place for the Fund’s full fiscal year ended June 30, 2012 or for the full calendar year ended December 31, 2011.  Amounts do not include expenses reimbursed to Trustees for attending Board meetings, which in the aggregate amounted to $48,518 for the calendar year ended December 31, 2011.  Heidi L. Steiger resigned as a Trustee effective November 29, 2010.  For the calendar year ended December 31, 2011, Ms. Steiger received $35,000 from the Fund and Fund Complex.  Mr. Eston and Ms. Taggart became Trustees effective September 1, 2011, and thus the compensation figures listed for the Fund and Fund Complex are estimated based on amounts each would have received if they had been Trustees for the 2011 calendar year and for the fiscal year ended June 30, 2012.

Trustees of the Fund who are not affiliated with Eaton Vance may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of a Trustees Deferred Compensation Plan (the “Trustees’ Plan”).  Under the Trustees’ Plan, an eligible Trustee may elect to have his or her deferred fees invested by the Fund in the shares of one or more funds in the Eaton Vance Fund Complex, and the amount paid to the Trustees under the Trustees’ Plan will be determined based upon the performance of such investments.  Deferral of Trustees’ fees in accordance with the Trustees’ Plan will have a negligible effect on the Fund’s assets, liabilities, and net income per share, and will not obligate the Fund to retain the services of any Trustee or obligate the Fund to pay any particular level of compensation to the Trustee.  The Fund does not have a retirement plan for its Trustees.

The Board of Trustees recommends that shareholders vote FOR the election of the four Class II Trustee and one Class III Trustee nominees.

NOTICE TO BANKS AND BROKER/DEALERS

The Fund has previously solicited all Nominee and Broker/Dealer accounts as to the number of additional proxy statements required to supply owners of shares.  Should additional proxy material be required for beneficial owners, please call 1-866-439-6787, send an email to info@amstock.com or forward such requests to American Stock Transfer & Trust Company, 59 Maiden Lane, New York, NY 10038.

Proxy Statement dated August 24, 2012

Deloitte & Touche LLP (“Deloitte”), 200 Berkeley Street, Boston, Massachusetts 02116, serves as the independent registered public accounting firm of the Fund.  Deloitte is not expected to be present at the Annual Meeting, but has been given the opportunity to make a statement if they desire to do so and will be available should any matter arise requiring their presence.

The following table presents the aggregate fees billed for the two fiscal years ended June 30, 2012 and 2011 by the Fund’s independent registered public accounting firm for professional services rendered for the audit of the Fund’s annual financial statements and fees billed for other services rendered by the independent registered public accounting firm during these periods.

No services described in the table above were approved by the Fund’s Audit Committee pursuant to the “de minimis exception” set forth in Rule 2-01(c)(7)(i)(C) of Regulation S-X.

The Fund’s Audit Committee has adopted policies and procedures relating to the pre-approval of services provided by the Fund’s independent registered public accounting firm (the “Pre-Approval Policies”).  The Pre-Approval Policies establish a framework intended to assist the Audit Committee in the proper discharge of its pre-approval responsibilities.  As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the Audit Committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees.  Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the Audit Committee.  The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the Fund’s Audit Committee at least annually.  The Fund’s Audit Committee maintains full responsibility for the appointment, compensation, and oversight of the work of the Fund’s independent registered public accounting firm.

The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed for services rendered to the Fund by the Fund’s independent registered public accounting firm for the two fiscal years ended June 30, 2012 and 2011; and (ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed for services rendered to the Eaton Vance Organization by the Fund’s independent registered public accounting firm for the two fiscal years ended June 30, 2012 and 2011.

The Fund’s investment adviser, as well as any of its affiliates that provide ongoing services to the Fund, are subsidiaries of EVC.

The Fund’s Audit Committee has considered whether the provision by the Fund’s independent registered public accounting firm of non-audit services to the Fund’s investment adviser, as well as any of its affiliates that provide ongoing services to the Fund, that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the independent registered public accounting firm’s independence.

Proxy Solicitation and Tabulation

The expense of preparing, printing and mailing this Proxy Statement and enclosures and the costs of soliciting proxies on behalf of the Board of Trustees of the Fund will be borne by the Fund.  Proxies will be solicited by mail and may be solicited in person or by telephone or facsimile by officers of the Fund, by personnel of its administrator, Eaton Vance, by the transfer agent, American Stock Transfer & Trust Company, by broker-dealer firms, or by a professional solicitation organization.  The expenses associated with the solicitation of these proxies and with any further proxies will be borne by the Fund.  A written proxy may be delivered to the Fund or its transfer agent prior to the meeting by facsimile machine, graphic communication equipment or similar electronic transmission.  The Fund will reimburse banks, broker-dealer firms, and other persons holding shares registered in their names or in the names of their nominees, for their expenses incurred in sending proxy material to and obtaining proxies from the beneficial owners of such shares.  Total estimated proxy solicitation costs are approximately $18,000.

All proxy cards solicited by the Board of Trustees that are properly executed and received by the Secretary prior to the meeting, and which are not revoked, will be voted at the meeting.  Shares represented by such proxies will be voted in accordance with the instructions thereon.  If no specification is made on the proxy card with respect to Proposal 1, it will be voted FOR the matters specified on the proxy card.  All shares that are voted and votes to ABSTAIN will be counted towards establishing a quorum, as will broker non-votes.  (Broker non-votes are shares for which (i) the beneficial owner has not voted and (ii) the broker holding the shares does not have discretionary authority to vote on the particular matter.)  Accordingly, abstentions and broker non-votes, which will be treated as shares that are present at the meeting but which have not been voted, will assist the Fund in obtaining a quorum but will have no effect on the outcome of Proposal 1.



Eaton Vance Senior Income Trust

Proxy Statement dated August 24, 2012


A quorum requires the presence, in person or by proxy, of a majority of the outstanding shares of the Fund entitled to vote.  In the event that a quorum is not present at the meeting, or if a quorum is present at the meeting but sufficient votes by the shareholders of the Fund in favor of the Proposal set forth in the Notice of this meeting are not received by October 26, 2012, the persons named as attorneys in the enclosed proxy may propose one or more adjournments of the meeting to permit further solicitation of proxies.  Any such adjournment will require the affirmative vote of the holders of a majority of the shares present in person or by proxy at the session of the meeting to be adjourned.  The persons named as attorneys in the enclosed proxy will vote in favor of such adjournment those proxies which they are entitled to vote in favor of the Proposal for which further solicitation of proxies is to be made.  They will vote against any such adjournment those proxies required to be voted against such Proposal.  The costs of any such additional solicitation and of any adjourned session will be borne by the Fund.  If any of the nominees are not elected by shareholders, the current Trustees may consider other courses of action.

Section 16(a) Beneficial Ownership Reporting Compliance

A-1


The primary function of the Committee is oversight.  The Committee is not responsible for managing the Funds or for performing tasks that are delegated to the officers of any Fund, any investment adviser to a Fund, the custodian of a Fund, and other service providers for the Funds, and nothing in this charter shall be construed to reduce the responsibilities or liabilities of management or the Funds’ service providers, including the independent auditors.  It is management’s responsibility to maintain appropriate systems for accounting and internal control over financial reporting.  Specifically, management is responsible for: (1) the preparation, presentation and integrity of the financial statements of each Fund; (2) the maintenance of appropriate accounting and financial reporting principles and policies; and (3) the maintenance of internal control over financial reporting and other procedures designed to assure compliance with accounting standards and related laws and regulations.  The independent auditors are responsible for planning and carrying out an audit consistent with applicable legal and professional standards and the terms of their engagement letter, and shall report directly to the Committee.  In performing its oversight function, the Committee shall be entitled to rely upon advice and information that it receives in its discussions and communications with management, the independent auditors and such experts, advisors and professionals as may be consulted by the Committee.   

III. Meetings of the Committee.

Meetings of the Committee shall be held at such times (but not less frequently than annually), at such places and for such purposes (consistent with the purposes set forth in this charter) as determined from time to time by the Board of Trustees, the Chairperson of the Board of Trustees, the Committee or the Chairperson of the Committee.  The Committee shall set its agenda and the places and times of its meetings.  The Committee may meet alone and outside the presence of management personnel with any auditor of a Fund, and shall periodically meet separately with management, with internal auditors (or other personnel responsible for internal control of financial reporting), with any independent auditors rendering reports to the Committee or the Board of Trustees and with legal counsel.  A majority of the members of the Committee shall constitute a quorum for the transaction of business at any meeting, and the decision of a majority of the members present and voting shall determine any matter submitted to a vote.  The Committee may adopt such procedures or rules as it deems appropriate to govern its conduct under this charter.  Each Independent Trustee of the Board of Trustees shall receive notice of all Committee meetings, and such meetings shall be open for any Independent Trustee to attend.

IV. Duties and Powers of the Committee.

To carry out its purposes, the Committee shall have the following duties and powers with respect to each Fund:

1.

To meet to review and discuss with management and the independent auditors the audited financial statements and other periodic financial statements of the Fund (including the Fund’s specific disclosures under the item “Management’s Discussion of Fund Performance”); provided that discussion with the independent auditors shall not be required with respect to any periodic financial statement of the Fund that was not the subject of a review by such auditors.

2.

To consider the results of the examination of the Fund’s financial statements by the independent auditors, the independent auditors’ opinion with respect thereto, and any management letter issued by the independent auditors.

3.

To review and discuss with the independent auditors: (a) the scope of audits and audit reports and the policies relating to internal auditing procedures and controls and the accounting principles employed in the Fund’s financial reports and any proposed changes therein; (b) the personnel, staffing, qualifications and experience of the independent auditors; and (c) the compensation of the independent auditors.

4.

To review and assess the performance of the independent auditors and to approve, on behalf of the Board of Trustees, the appointment and compensation of the independent auditors.  Approval by the Committee shall be in addition to any approval required under applicable law by a majority of the members of the Board of Trustees who are not “interested persons” of the Fund as defined in Section 2(a)(19) of the 1940 Act.  In performing this function, the Committee shall: (a) consider whether there should be a regular rotation of the Fund’s independent auditing firm; (b) discuss with the independent auditors matters bearing upon the qualifications of such auditors as “independent” under applicable standards of independence established from time to time by the Securities and Exchange Commission (“SEC”), the Public Company Accounting Oversight Board and other regulatory authorities; and (c) shall secure from the independent auditors the information required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as in effect from time to time.  The Committee shall actively engage in a dialogue with the independent auditors with respect to any disclosed relationships or services that may impact the objectivity and independence of the independent auditors.



A-2


5.

To pre-approve: (a) audit and non-audit services provided by the independent auditors to the Fund; and (b) non-audit services provided by the independent auditors to the adviser or any other entity controlling, controlled by or under common control with the adviser that provides on-going services to the Fund (“Adviser Affiliates”) if the engagement of the independent auditors relates directly to the operations and financial reporting of the Fund, as contemplated by the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and the rules issued by the SEC in connection therewith (except, in the case of non-audit services provided to the Fund or any Adviser Affiliate, those within applicable de minimis statutory or regulatory exceptions), and to consider the possible effect of providing such services on the independence of the independent auditors.

6.

To adopt, to the extent deemed appropriate by the Committee, policies and procedures for pre-approval of the audit or non-audit services referred to above, including policies and procedures by which the Committee may delegate to one or more of its members authority to grant such pre-approval on behalf of the Committee (subject to subsequent reporting to the Committee).  The Committee hereby delegates to each of its members the authority to pre-approve any non-audit services referred to above between meetings of the Committee, provided that: (i) all reasonable efforts shall be made to obtain such pre-approval from the Chairperson of the Committee prior to seeking such pre-approval from any other member of the Committee; and (ii) all such pre-approvals shall be reported to the Committee not later than the next meeting thereof.

7.

To consider the controls implemented by the independent auditors and any measures taken by management to ensure that all items requiring pre-approval by the Committee are identified and referred to the Committee in a timely fashion.

8.

To receive at least annually and prior to the filing with the SEC of the independent auditors’ report on the Fund’s financial statements, a report from such independent auditors of:  (i) all critical accounting policies and practices used by the Fund (or, in connection with any update, any changes in such accounting policies and practices), (ii) all material alternative accounting treatments within GAAP that have been discussed with management since the last annual report or update, including the ramifications of the use of the alternative treatments and the treatment preferred by the accounting firm, (iii) other material written communications between the independent auditors and the management of the Fund since the last annual report or update, (iv) a description of all non-audit services provided, including fees associated with the services, to any fund complex of which the Fund is a part since the last annual report or update that was not subject to the pre-approval requirements as discussed above; and (v) any other matters of concern relating to the Fund’s financial statements, including any uncorrected misstatements (or audit differences) whose effects management believes are immaterial, both individually and in aggregate, to the financial statements taken as a whole.  If this information is not communicated to the Committee within 90 days prior to the audit report’s filing with the SEC, the independent auditors will be required to provide an update, in the 90 day period prior to the filing, of any changes to the previously reported information.

9.

To review and discuss with the independent auditors the matters required to be communicated with respect to the Fund pursuant to Statement on Auditing Standards (SAS) No. 61 “Communication With Audit Committees,” as in effect from time to time, and to receive such other communications or reports from the independent auditors (and management’s responses to such reports or communications) as may be required under applicable listing standards of the national securities exchanges on which the Fund’s shares are listed, including a report describing: (1) the internal quality-control procedures of the independent auditors, any material issues raised by the most recent internal quality-control review, or peer review, of the independent auditors, or by any inquiry or investigation by governmental or professional regulatory authorities, within the preceding five years, respecting one or more independent audits carried out by the independent auditors, and any steps taken to deal with any such issues; and (2) all relationships between the independent auditors and the Fund and any other relationships or services that may impact the objectivity and independence of the independent auditors.  To the extent unresolved disagreements exist between management and the independent auditors regarding the financial reporting of the Fund, it shall be the responsibility of the Committee to resolve such disagreements.

10.

To consider and review with the independent auditors any reports of audit problems or difficulties that may have arisen in the course of the audit, including any limitations on the scope of the audit, and management’s response thereto.

11.

To establish hiring policies for employees or former employees of the independent auditors who will serve as officers or employees of the Fund.  



A-3


12.

With respect to each Fund the securities of which are listed on a national securities exchange, to: (a) provide a recommendation to the Board of Trustees regarding whether the audited financial statements of the Fund should be included in the annual report to shareholders of the Fund; and (b) to prepare an audit committee report consistent with the requirements of Rule 306 of Regulation S-K for inclusion in the proxy statement for the Fund’s annual meeting of shareholders.

13.

To discuss generally the Fund’s earnings releases, as well as financial information and guidance provided to analysts and rating agencies, in the event a Fund issues any such releases or provides such information or guidance.  Such discussions may include the types of information to be disclosed and the type of presentation to be made.  The Committee need not discuss in advance each earnings release or each instance in which earnings guidance may be provided.

14.

To consider the Fund’s major financial risk exposures and the steps management has taken to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken.

15.

To review and report to the Board of Trustees with respect to any material accounting, tax, valuation, or record-keeping issues which may affect the Fund, its respective financial statements or the amount of their dividend or distribution rates.

16.

To establish procedures for:  (a) the receipt, retention, and treatment of complaints received by the Fund regarding accounting, internal accounting controls, or auditing matters; and (b) the confidential, anonymous submission by employees of the Fund or its service providers (including its investment advisers, administrators, principal underwriters and any other provider of accounting related services to the Fund) of concerns regarding questionable accounting or auditing matters.

17.

To direct and supervise investigations with respect to the following: (a) evidence of fraud or significant deficiencies in the design or implementation of internal controls reported to the Committee by the principal executive or financial officers of the Fund pursuant to the requirements of the Sarbanes-Oxley Act and related rules; and (b) any other matters within the scope of this charter, including the integrity of reported facts and figures, ethical conduct, and appropriate disclosure concerning the financial statements of the Funds.

18.

To review and recommend to the Board of Trustees policies and procedures for valuing portfolio securities of the Fund and to make recommendations to the Board of Trustees with respect to specific fair value determinations and any pricing errors involving such portfolio securities.

19.

To coordinate its activities with the other committees of the Board of Trustees as necessary or appropriate and to communicate with such other committees regarding any material concerns or questions such committees may wish to consider in exercising their respective powers.

20.

To act on such other matters as may be delegated to the Committee by the Board of Trustees from time to time.
