INTRODUCTION This proxy statement is being used by the Board of Trustees of each fund to solicit proxies to be voted at the annual meeting of shareholders of each of the funds referenced above. Participating in the meeting are holders of common shares of beneficial interest (the "Common Shares") and the holders of preferred shares of beneficial interest (the "Preferred Shares") of each fund. The Common Shares and the Preferred Shares of each fund sometimes are referred to herein collectively as the "Shares". Each meeting will be held at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, 26th Floor, Boston, Massachusetts 02109, at 2:00 p.m., Boston time, on July 25, 2006, and at any adjournments of a meeting to a later date, for the purposes as set forth in the accompanying notice of annual meeting of shareholders. This proxy statement and the enclosed proxy card are being mailed to shareholders of each fund on or about June 14, 2006. The annual report for each fund for its most recently completed fiscal year was previously mailed to shareholders. WHO IS ELIGIBLE TO VOTE Shareholders of record of each fund as of the close of business on June 2, 2006 (the "record date") are entitled to vote on all of the fund's business at the annual shareholder meeting and any adjournments thereof. The affirmative vote of a plurality of the Common and Preferred Shares of each fund present at the meeting in person or by proxy, voting together as a single class, is required to elect each nominee for Trustee designated to be elected by the Common and Preferred Shares of each fund. The affirmative vote of a plurality of the Preferred Shares of each fund present at the meeting in person or by proxy is required to elect each nominee for Trustee designated to be elected by the Preferred 1 Shares of each fund. Election by plurality means those persons who receive the highest number of votes cast "FOR" up to the total number of persons to be elected as Trustees at the meeting shall be elected. Shares represented by properly executed proxies, unless revoked before or at the meeting, will be voted according to the shareholder's instructions. If you sign a proxy but do not fill in a vote, your shares will be voted in favor of each of the nominees for Trustee. If any other business comes before the annual shareholder meeting, your shares will be voted at the discretion of the persons named as proxies. Each fund will vote separately on each item. Votes of multiple funds will not be aggregated. PROPOSAL 1 ELECTION OF BOARD OF TRUSTEES Shareholders of each fund are being asked to consider the election of three nominees to the Board of Trustees of each fund. All of the nominees for election to each fund's Board currently serve as Trustees for the fund and have served in that capacity continuously since originally elected or appointed. Each Trustee shall be elected to hold office for a three year term or until his or her successor is elected and qualified. Each nominee has consented to being named in this proxy statement and indicated his or her willingness to serve if elected. In the unanticipated event that any nominee should be unable to serve, the persons named as proxies may vote for such other person as shall be designated by the fund's Board of Trustees. The persons named on the accompanying proxy card intend to vote at the meeting (unless otherwise directed) for the election of the nominees named below as Trustees of each fund. The Declaration of Trust for each fund provides that the Board of Trustees shall consist of Trustees divided into three classes, the classes to be as nearly equal in number as possible. The Trustees of only one class are elected at each annual meeting so that the regular term of only one class of Trustees will expire annually and any particular Trustee stands for election only once in each three year period. Each fund's Board of Trustees is divided into three staggered term classes -- Class I, Class II and Class III. Class II Trustees are being submitted to shareholders for election at the meeting for Pioneer Tax Advantaged Balanced Trust. Class III Trustees are being submitted to shareholders for election at the meeting for Pioneer Floating Rate Trust. Each fund's Board of Trustees consists of nine members. Pioneer Floating Rate Trust The terms of the Class I Trustees -- Mr. Cogan, Mr. Bock and Mr. West -- expire in 2007; the terms of the Class II Trustees -- Ms. Graham, Mr. Hood and Mr. Winthrop -- expire in 2008; and the terms of the Class III Trustees -- Ms. Bush, Mr. Perna and Ms. Piret -- expire at the upcoming 2006 annual meeting. 2 Pioneer Tax Advantaged Balanced Trust The terms of the Class I Trustees -- Ms. Graham, Mr. Hood and Mr. Winthrop -- expire in 2008; the terms of the Class II Trustees -- Ms. Bush, Mr. Perna and Ms. Piret -- expire at the upcoming 2006 annual meeting; and the terms of the Class III Trustees -- Mr. Cogan, Mr. Bock and Mr. West -- expire in 2007. Subsequently, for each fund, each class of Trustees will stand for election at the conclusion of its respective three year term. Such classification may prevent replacement of a majority of the Trustees for up to a two-year period. Mr. Cogan and Ms. Piret have been designated as the Trustees to be elected by the holders of the Preferred Shares of each fund. The following table sets forth the incumbent Trustees and each Trustee's position(s) with each fund, his or her age, address, principal occupation and employment during the past five years and any other directorship held. Trustees who are interested persons of a fund within the meaning of the Investment Company Act of 1940, as amended (the "1940 Act") are referred to as Interested Trustees. Trustees who are not interested persons of a fund are referred to as Independent Trustees. Each of the Trustees (except Mr. Hood and Mr. West) serves as a Trustee of each of the 91 U.S. registered investment portfolios for which Pioneer Investment Management, Inc. ("Pioneer") serves as investment adviser (the "Pioneer Funds"). Mr. Hood and Mr. West each serves as Trustee of 35 of the 91 Pioneer Funds. The address of all Interested Trustees is 60 State Street, Boston, Massachusetts 02109. 3 Other Term of Office Directorships Position(s) and Held by this Name, Age Held Length of Principal Occupation(s) Trustee or and Address With the Fund Service During Past Five Years Nominee -------------------- --------------- ------------------- ---------------------------- ------------------ Interested Trustees: John F.

Committee members are as follows: Audit David R. Bock, Margaret B.W. Graham, Marguerite A. Piret (Chair) and Stephen K. West Independent Trustees David R. Bock, Mary K. Bush, Margaret B.W. Graham (Chair), Thomas J. Perna, Marguerite A. Piret, Stephen K. West and John Winthrop Nominating Mary K. Bush, Marguerite A. Piret and John Winthrop (Chair) Valuation David R. Bock, Margaret B.W. Graham and Marguerite A. Piret (Chair) Policy Administration Mary K. Bush (Chair), Thomas J. Perna and John Winthrop During the most recent fiscal year, the Audit, Nominating, Valuation, Independent Trustees and Policy Administration Committees of each fund held the following meetings: Tax Advantaged Floating Rate Trust Balanced Trust --------------------- --------------- Audit Committee ......................... 18 18 Nominating Committee .................... 9 9 Valuation Committee ..................... 5 5 Independent Trustees .................... 16 16 Policy Administration Committee ......... 9 9 All members of the Audit Committee are "independent", as defined in the applicable listing standard of the New York Stock Exchange currently in effect. The Board of Trustees has adopted a charter for the Audit Committee, in effect as of March 15, 2005. In accordance with its charter, the purposes of the Audit Committee are to: o act as a liaison between the fund's independent registered public accounting firm and the full Board of Trustees of the fund; o discuss with the fund's independent registered public accounting firm their judgments about the quality of the fund's accounting principles and underlying estimates as applied in the fund's financial reporting; 8 o review and assess the renewal materials of all related party contracts and agreements, including management advisory agreements, underwriting contracts, administration agreements, distribution contracts, and transfer agency contracts, among any other instruments and agreements that may be appropriate from time to time; o review and approve insurance coverage and allocations of premiums between the management and the fund and among the Pioneer Funds; o review and approve expenses under the administration agreement between Pioneer and the fund and allocations of such expenses among the Pioneer Funds; and o receive on a periodic basis a formal written statement delineating all relationships between the independent registered public accounting firm and the fund or Pioneer; to actively engage in a dialogue with the independent registered public accounting firm with respect to any disclosed relationships or services that may impact the objectivity and independence of the independent registered public accounting firm; and to recommend that the Trustees take appropriate action in response to the independent registered public accounting firm's report to satisfy itself of the firm's independence. The Audit Committee reports that it has (1) reviewed and discussed each fund's audited financial statements with management; (2) discussed with the independent registered public accounting firm the matters relating to the quality of each fund's financial reporting; and (3) received written disclosures and an independence letter from the independent registered public accounting firm and discussed with the independent registered public accounting firm that firm's independence. Based upon the review and discussions referred to above, the Audit Committee recommended to the Board of Trustees that the audited financial statements be included in the Annual Reports for Pioneer Floating Rate Trust and Pioneer Tax Advantaged Balanced Trust for the fiscal year ended November 30, 2005, for filing with the Securities and Exchange Commission (the "SEC"). Each fund's Board of Trustees has determined that each fund has at least one audit committee financial expert. Ms. Marguerite A. Piret, an independent trustee, is the audit committee's financial expert. All members of the Nominating Committee are independent under the New York Stock Exchange's Revised Listing Rules and are not interested persons, as defined in the 1940 Act, of Pioneer. The Board of each fund has adopted a written charter for the Nominating Committee, which is available on Pioneer's website: www.pioneerfunds.com. The Nominating Committee reviews the qualifications of persons being considered as candidates as Trustees and makes recommendations regarding the qualifications of such persons to the Independent Trustees. All of the Independent Trustees then evaluate any candidate and determine whether to nominate them for election. The Trustees who are not Independent Trustees and the officers of each fund are nominated and selected by the Board. 9 The Nominating Committee's charter provides for certain criteria to be used in evaluating candidates for Independent Trustee. In reviewing a potential nominee and in evaluating the re-nomination of current Independent Trustees, the Nominating Committee applies the following criteria: (i) the nominee's reputation for integrity, honesty and adherence to high ethical standards, (ii) the nominee's business acumen and ability to exercise sound judgments, (iii) a commitment to attend and participate in meetings of the Board and its committees, (iv) the ability to understand potential conflicts of interest in managing a fund and to act in the interests of all shareholders, and (v) the absence of a real or apparent conflict of interest that would impair the nominee's ability to represent the interests of all the shareholders and to fulfill the responsibilities of an Independent Trustee. The Nominating Committee does not necessarily place the same emphasis on each criteria and each nominee may not have each of these qualities. As long as an existing Independent Trustee continues, in the opinion of the other Independent Trustees, to satisfy these criteria and continues to make positive contributions to the Board, each fund anticipates that Independent Trustees of each fund would favor the re-nomination of an existing Trustee rather than a new candidate. Consequently, while the Nominating Committee will evaluate the qualifications of nominees recommended by shareholders to serve as Trustee, the Independent Trustees may only act upon the Nominating Committee's evaluation if there is a vacancy on the Board. In the event that a vacancy arises or a change in Board membership is determined to be advisable, the Nominating Committee will, in addition to any shareholder recommendations, evaluate candidates identified by other means, including candidates proposed by Independent Trustees or management. While it has not done so in the past, the Nominating Committee may retain a consultant to assist the Committee in a search for a qualified candidate. Any shareholder recommendation must be submitted in compliance with all of the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the "Exchange Act") to be considered by the Nominating Committee. In evaluating a nominee recommended by a shareholder, the Nominating Committee, in addition to the criteria discussed above, may consider the objectives of the shareholder in submitting that nomination and whether such objectives are consistent with the interests of all shareholders. If the Board determines to include a shareholder's candidate among the slate of nominees, the candidate's name will be placed on the fund's proxy card. If the Nominating Committee, the Independent Trustees or the Board determines not to include such candidate among the Board's designated nominees and the shareholder has satisfied the requirements of Rule 14a-8, the shareholder's candidate will be treated as a nominee of the shareholder who originally nominated the candidate. The Nominating Committee initiated the recommendation of each of the nominees to serve as Independent Trustee. 10 Shareholders may communicate with the members of the Board as a group or individually. Any such communication should be sent to the Board or an individual Trustee c/o the Secretary of the fund at the address on the notice of this meeting. The Secretary may determine not to forward any letter to members of the Board that does not relate to the business of a fund. The Valuation Committee reviews the valuation assigned to certain securities by Pioneer in accordance with each fund's valuation procedures. The Policy Administration Committee reviews the implementation of certain of each fund's administrative policies and procedures. The Independent Trustees Committee reviews each fund's management contract and other related party contracts annually and is also responsible for any other action required to be taken, under the 1940 Act, by the Independent Trustees acting alone. Each fund's Declaration of Trust provides that the fund will indemnify the Trustees and officers against liabilities and expenses reasonably incurred in connection with any litigation in which they may be involved because of their offices with the fund, unless it is determined in the manner specified in the Declaration of Trust that they have not acted in good faith in the reasonable belief that their actions were in the best interests of the fund or that such indemnification would relieve any officer or Trustee of any liability to the fund or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. During each fund's most recent fiscal year, the Board of Trustees held 14 meetings. All of the current Trustees and committee members of each fund then serving attended at least 75% of the meetings of the Board of Trustees and applicable committees, if any, held during that fund's fiscal year. The following table indicates the value of shares that each Trustee or nominee beneficially owned in each fund and Pioneer Funds in the aggregate as of April 30, 2006. Beneficial ownership is determined in accordance with SEC rules. The share value of any closed-end Pioneer fund is based on its closing market price on April 30, 2006. The share value of any open-end Pioneer fund is based on the net asset value of the class of shares on April 30, 2006. The dollar ranges in this table are in accordance with SEC requirements. 11 Aggregate Dollar Range of Equity Securities in All Pioneer Funds Dollar Range of Overseen or to be Equity Securities Overseen by Trustee Name of Trustee or Nominee in each Fund or Nominee ------------------------------- ---------------------- ------------------------ INTERESTED TRUSTEE or NOMINEE John F.

("PFD"). Material Relationships of the Independent Trustees For purposes of the statements below: o the immediate family members of any person are their spouse, children in the person's household (including step and adoptive children) and any dependent of the person. o an entity in a control relationship means any person who controls, is controlled by or is under common control with the named person. For example, UniCredito Italiano is an entity that is in a control relationship with Pioneer. 12 o a related fund is a registered investment company or an entity exempt from the definition of an investment company pursuant to Sections 3(c)(1) or 3(c)(7) of the 1940 Act, for which Pioneer or any of its affiliates act as investment adviser or for which PFD or any of its affiliates act as principal underwriter. For example, each fund's related funds include all of the Pioneer Funds and any non-U.S. funds managed by Pioneer or its affiliates. As of December 31, 2005, for each fund, none of the Independent Trustees, nor any of their immediate family members, beneficially owned any securities issued by Pioneer, UniCredito Italiano or any other entity in a control relationship to Pioneer or PFD. During the past five years, for each fund, none of the Independent Trustees, nor any of their immediate family members, had any direct or indirect interest (the value of which exceeded $60,000), whether by contract, arrangement or otherwise, in Pioneer, UniCredito Italiano, or any other entity in a control relationship to Pioneer or PFD. During the past five years, for each fund, none of the Independent Trustees, nor any of their immediate family members, had an interest in a transaction or a series of transactions, or in any currently proposed transaction, or series of similar transactions, in which the aggregate amount involved exceeded $60,000 and to which any of the following were a party (each a "fund related party"): o the fund o an officer of the fund o a related fund o an officer of any related fund o Pioneer or PFD o Highland Capital Management, L.P. ("Highland"), the subadviser for Pioneer Floating Rate Trust o an officer of Pioneer, PFD or Highland o any affiliate of Pioneer, PFD or Highland o an officer of any such affiliate During the calendar years 2004 and 2005, for each fund, none of the Independent Trustees, nor any of their immediate family members, had any relationship (the value of which exceeded $60,000) with any fund related party, including, but not limited to, relationships arising out of (i) the payment for property and services, (ii) the provision of legal services, (iii) the provision of investment banking services (other than as a member of the underwriting syndicate) or (iv) the provision of consulting services, except that Mr. West, an Independent Trustee, is Senior Counsel to Sullivan & Cromwell and acts as counsel to the Independent Trustees and the Independent Trustees of certain other 13 Pioneer Funds. The aggregate compensation paid to Sullivan & Cromwell by the funds and the other Pioneer Funds was approximately $208,010 and $173,353 in 2004 and 2005, respectively. During the calendar years 2004 and 2005, for each fund, none of the Independent Trustees, nor any of their immediate family members, served as a member of a board of directors on which an officer of any of the following entities also serves as a director: o Pioneer o PFD o Highland o UniCredito Italiano o any other entity in a control relationship with Pioneer, PFD or Highland None of the funds' Trustees or officers has any arrangement with any other person pursuant to which that Trustee or officer serves on the Board of Trustees. During the calendar years 2004 and 2005, for each fund, none of the Independent Trustees, nor any of their immediate family members, had any position, including as an officer, employee, director or partner, with any of the following: o the fund o any related fund o Pioneer o PFD o Highland o any affiliated person of the fund, Pioneer, PFD or Highland o UniCredito Italiano o any other entity in a control relationship to the fund, Pioneer, PFD or Highland Compliance with Section 16(a) Reporting Requirements Section 16(a) of the Exchange Act requires each fund's executive officers, Trustees and person who own more than ten percent of a fund's shares ("10% Shareholders") to file reports of ownership and changes in ownership with the SEC. Executive officers, Trustees and 10% Shareholders are required by SEC regulations to furnish the fund with copies of all Section 16(a) forms they file. Except as noted below, based solely on a review of the copies of these reports furnished to each of the funds and representations that no other reports were required to be filed, each fund believes that during the past fiscal year its executive officers, Trustees and 10% Shareholders complied with all applicable Section 16(a) filing requirements. Due to an error by each fund and not the Trustee, Forms 3 for Mr. Bock and Mr. Perna were filed subsequent to the required date for such filings. Forms 4, if any, showing changes in ownership of each fund's securities by such Trustees were filed in a timely manner. 14 Other executive officers In addition to Mr. Cogan and Mr. Hood, who serve as President and Executive Vice President, respectively, of each fund, the following table provides information with respect to the other executive officers of the funds. Each executive officer is elected by the Board of Trustees and serves until his or her successor is chosen and qualified or until his or her resignation or removal by the Board.

Pioneer has retained Highland Capital Management, L.P. to act as subadviser to Pioneer Floating Rate Trust. The Trustees may, but generally do not, attend shareholder meetings. John F. Cogan, Jr. attended the 2005 annual shareholder meeting. Required vote In accordance with each fund's agreement and declaration of trust, the holders of Common Shares and Preferred Shares of each fund will vote on the respective nominees designated to be elected by such class of shares. Ms. Bush, Mr. Perna and Ms. Piret are the current nominees for election for each fund. Ms. Bush and Mr. Perna are each elected by the holders of Common and Preferred Shares. Ms. Piret is elected by the holders of Preferred Shares, only. The affirmative vote of a plurality of the Common and Preferred Shares for each fund present at the meeting in person or by proxy, voting together as a single class, is required to elect such nominee for Trustee designated to be elected by the Common and Preferred Shares. The affirmative vote of a plurality of the Preferred Shares for each fund present at the meeting in person or by proxy is required to elect such nominee for Trustee designated to be elected by the Preferred Shares. This means that the three nominees receiving the greatest number of votes will be elected as Class II Trustees to the Board of Pioneer Tax Advantaged Balanced Trust and Class III Trustees to the Board of Pioneer Floating Rate Trust. Recommendation For the reasons set forth above, the Trustees of your fund unanimously recommend that shareholders vote in favor of each of the nominees. 18 AUDITOR INFORMATION Audit fees The aggregate fees billed for professional services rendered by Ernst & Young LLP for its audit of each fund's annual financial statements and fees related to consents and comfort letters for the two most recent fiscal years contained in the annual reports filed by each fund for such years were as follows: For the fiscal year For the fiscal year ended 11/30/2005 ended 11/30/2004 --------------------- -------------------- Pioneer Floating Rate Trust ................... $83,500 n/a Pioneer Tax Advantaged Balanced Trust ......... $35,075 $80,500 Audit-related fees The following are aggregate fees billed for assurance and related services by Ernst & Young LLP to each fund that are related to the review of each fund's semi-annual financial statements and agreed upon procedures related to the ratings of each fund's Preferred Shares for the two most recent fiscal years. All of these services were approved by the Audit Committee of each fund pursuant to Regulation S-X. For the fiscal year For the fiscal year ended 11/30/2005 ended 11/30/2004 --------------------- -------------------- Pioneer Floating Rate Trust ................... $14,500 n/a Pioneer Tax Advantaged Balanced Trust ......... $ 8,500 $13,000 Tax fees The aggregate fees billed for professional services, primarily for tax returns, rendered by Ernst & Young LLP for tax compliance, tax advice and tax planning to each fund for the two most recent fiscal years were as follows. All of these services were approved by the Audit Committee of each fund pursuant to Regulation S-X. For the fiscal year For the fiscal year ended 11/30/2005 ended 11/30/2004 --------------------- -------------------- Pioneer Floating Rate Trust ................... $6,800 n/a Pioneer Tax Advantaged Balanced Trust ......... $6,800 $6,000 All other fees There were no fees billed for other services rendered by Ernst & Young LLP to the funds. 19 Affiliates' Fees for Non-Audit Services Required to be Pre-Approved Beginning with non-audit service contracts entered into on or after May 6, 2003, the effective date of the new SEC pre-approval rules, each fund's audit committee is required to pre-approve services to affiliates as defined by SEC rules to the extent that the services are determined to have a direct impact on the operations or financial reporting of the fund. Affiliates include the fund's investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the fund (hereinafter referred to as "affiliates" of the fund). For the years ended November 30, 2005 and 2004, for each of the funds, there were no services provided to an affiliate that required the fund's audit committee pre-approval. General Audit Committee Approval Policy o For all projects, the officers of the funds and the funds' independent registered public accounting firm will each make an assessment to determine that any proposed projects will not impair independence. o Potential services will be classified into the four non-restricted service categories and the "Approval of Audit, Audit-Related, Tax and Other Services" Policy will be applied. Any services outside the specific pre-approved service subcategories set forth above must be specifically approved by the Audit Committee. o At least quarterly, the Audit Committee shall review a report summarizing the services by service category, including fees, provided by the independent registered public accounting firm as set forth in the above policy. Aggregate Non-Audit Fees The aggregate non-audit fees for each fund and its affiliates, as previously defined, were as follows. These fees include services provided prior to May 6, 2003, the effective date of the pre-approval process. For the fiscal year For the fiscal year ended 11/30/2005 ended 11/30/2004 --------------------- -------------------- Pioneer Floating Rate Trust ................... $21,300 n/a Pioneer Tax Advantaged Balanced Trust ......... $15,300 $19,000 The Audit Committee of the Board of each fund has considered whether the provision of services, other than audit services, by Ernst & Young LLP to each fund and its affiliates is compatible with maintaining Ernst & Young LLP's independence in performing audit services. Representatives of Ernst & Young LLP will be available at the shareholder meeting (either in person or via telephone), will have the opportunity to make a statement should they desire to do so, and will be available to answer questions. 20 INFORMATION CONCERNING THE MEETING Outstanding shares and quorum As of the record date, the following common and preferred shares of beneficial interest were outstanding for each fund: Common shares Preferred shares -------------------------------------------------------------------------------------- Pioneer Floating Rate Trust .................... 24,330,240 3,130 Series M7 3,125 Series W7 3,125 Series TH7 Pioneer Tax Advantaged Balanced Trust .......... 28,706,981 2,350 Series T7 2,350 Series F7 2,350 Series TH28 Only shareholders of record as of the record date are entitled to notice of and to vote at the meeting.

A proposal that is not to be included in the fund's proxy statement may only be made at the 2007 annual meeting if it is received by the Secretary of the fund at the fund's principal offices at 60 State Street, Boston, Massachusetts 02109 not more than 120 days and at least 90 days before the anniversary date of the mailing of the fund's proxy materials for this year's annual meeting provided, however, that in the event that the date of the mailing of the notice for the 2007 annual meeting is advanced or delayed by more than thirty (30) days from the anniversary date of the mailing of the notice for this year's annual meeting, notice by a shareholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to the date of mailing of the notice for the 2007 annual meeting and not later than the close of business on the later of the 90th day prior to the date of mailing of the notice for the 2007 annual meeting or the 10th day following the day on which public announcement of the date of mailing of the notice for the 2007 meeting is first made by the fund. The submission by a shareholder of a proposal for inclusion in a proxy statement does not guarantee that it will be included. Each fund currently expects to hold the next annual shareholders' meeting on or about June 26, 2007, which date is subject to change. Shareholder proposals are subject to certain regulations under the federal securities laws. Proxies, quorum and voting at the meeting Any shareholder who has given his or her proxy to someone has the power to revoke that proxy at any time prior to its exercise by executing a superseding proxy or by submitting a notice of revocation to the secretary of the fund. In addition, although mere attendance at the meeting will not revoke a proxy, a shareholder present at the meeting may withdraw his or her proxy and vote in person. All properly executed and unrevoked proxies received in time for the meeting will be voted in accordance with the instructions contained in the proxies. If no instruction is given, the persons named as proxies will vote the shares represented thereby in favor of the nominees in Proposal No. 1, as described above, and will use their best judgment in connection with the transaction of such other business as may properly come before the meeting or any adjournment thereof. For each fund, one-third of the outstanding shares of each series or class, or one-third of the outstanding shares of the Trust, entitled to vote, present in person or represented by proxy, constitutes a quorum for the transaction of business at the meeting with respect to such series or class, or with respect to the entire fund, respectively. In the event that at the time any session of the meeting is called to order a quorum is not present in person or by proxy, the persons named as proxies may vote those proxies that have been received to adjourn the shareholder meeting to a later date. In the event that a quorum is present but sufficient votes in favor of the proposal have not been received, the persons named as proxies may propose one or more adjournments of the shareholder meeting to permit further solicitation of proxies with respect to such proposal. Any such adjournment will require the affirmative vote of more than one half of the shares of the 24 fund present in person or by proxy at the session of the meeting to be adjourned. The persons named as proxies will vote those proxies which they are entitled to vote in favor of any such proposal in favor of such an adjournment and will vote those proxies required to be voted against any such proposal against any such adjournment. A shareholder vote may be taken on one or more of the proposals in the proxy statement prior to such adjournment if sufficient votes for its approval have been received and it is otherwise appropriate. Such vote will be considered final regardless of whether the meeting is adjourned to permit additional solicitation with respect to any other proposal. Shares of the fund represented in person or by proxy, including shares that abstain or do not vote with respect to a proposal, will be counted for purposes of determining whether there is a quorum at the meeting. However, an abstention from voting has the same effect as a vote against a proposal. Similarly, if a broker or nominee holding shares in "street name" indicates on the proxy card that it does not have discretionary authority to vote on a proposal and has not received instructions from the beneficial owner, those shares will not be considered present and entitled to vote on that proposal. Thus, a "broker non-vote" has no effect on the voting. Other business While the meeting has been called to transact any business that may properly come before it, the only matters that the Trustees intend to present are those matters stated in the attached notice of annual meeting of shareholders. However, if any additional matters properly come before the meeting, and on all matters incidental to the conduct of the meeting, it is the intention of the persons named in the enclosed proxy to vote the proxy in accordance with their judgment on such matters unless instructed to the contrary. Method of solicitation and expenses The cost of preparing, assembling and mailing this proxy statement and the attached notice of annual meeting of shareholders and the accompanying proxy card for each fund will be borne by that fund. In addition to soliciting proxies by mail, Pioneer may, at the fund's expense, have one or more of the fund's officers, representatives or compensated third-party agents, including Pioneer, PIMSS and PFD, aid in the solicitation of proxies by personal interview or telephone and telegraph and may request brokerage houses and other custodians, nominees and fiduciaries to forward proxy soliciting material to the beneficial owners of the shares held of record by such persons. Each fund may also arrange to have votes recorded by telephone, the internet or other electronic means. The voting procedures used in connection with such voting methods are designed to authenticate shareholders' identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions and to confirm that their instructions have been properly recorded. If these procedures were subject to a successful legal challenge, such votes would not be counted at the shareholder meeting. Each fund is unaware of any such challenge at this time. In the case of telephone voting, shareholders would be called at the phone number the sub-transfer agent, Mellon Investor Services LLC, has in its records for their accounts, and would be asked for their Social Security number or other identifying information. The shareholders would then be given an opportunity to authorize proxies to vote their shares at the meeting in accordance with their instructions. 25 In the case of automated telephone and internet voting, shareholders would be required to provide their Social Security number or other identifying information and would receive a confirmation of their instructions. Persons holding shares as nominees will be reimbursed by Pioneer, upon request, for the reasonable expenses of mailing soliciting materials to the principals of the accounts.
