2. The disclosure under "Management of the Trust — Board Leadership Structure" is replaced with the following (with the exception of the number of committee meetings during the previous fiscal year, which remains):

Common Board of Trustees/Directors: The business of the Trust is managed under the direction of its Board. The Trustees also serve on the Boards of all the other investment companies that comprise Delaware Funds. The Trustees believe that having a common Board for all funds in the complex is efficient and enhances the ability of the Board to address its responsibilities to each fund in the complex. The Trustees believe that the common board structure allows the Trustees to leverage their individual expertise and that their judgment is enhanced by being Trustees of all of the funds in the complex.

Board Chair: Mr. Bennett is the Board's Chair. As fund governance best practices have evolved, more and more fund boards have opted to have an independent trustee serve as chair. Among other reasons, the Board selected Mr. Bennett as Chair due to his substantial financial industry experience and his tenure on the Board. As the Chair, Mr. Bennett, in consultation with Fund management, legal counsel, and the other Trustees, proposes Board agenda topics, actively participates in developing Board meeting agendas, and ensures that appropriate and timely information is provided to the Board in connection with Board meetings. Mr. Bennett also conducts meetings of the Independent Trustees. He also generally serves as a liaison among outside Trustees, Fund officers, and legal counsel, and is an ex officio member of the Nominating and Corporate Governance Committee.

Size and composition of Board: The Board is currently comprised of eleven Trustees. Ten of the eleven Trustees are independent. The Trustees believe that the current size of the Board is conducive to Board interaction, dialogue, and debate, resulting in an effective decision-making body. The Board comprises Trustees with a variety of professional backgrounds. The Board believes that the skill sets of its members are complementary and add to the overall effectiveness of the Board. The Trustees regard diversity as an important consideration in the present composition of the Board and the selection of qualified candidates to fill vacancies on the Board.

Committees: The Board has established several committees, each of which focuses on a particular substantive area and provides reports and recommendations to the full Board. The committee structure enables the Board to manage efficiently and effectively the large volume of information relevant to the Board's oversight of the Trust. The committees benefit from the professional expertise of their members. At the same time, membership on a committee enhances the expertise of its members and benefits the overall effectiveness of the Board.

The Board has the following committees:

Audit Committee: This committee monitors accounting and financial reporting policies, practices, and internal controls for the Trust. It also oversees the quality and objectivity of the Trust's financial statements and the independent audit thereof, and acts as a liaison between the Trust's independent registered public accounting firm and the full Board. The Trust's Audit Committee consists of the following Independent Trustees: Thomas K. Whitford, Chair; John A. Fry; Lucinda S. Landreth; Christianna Wood; and Janet L. Yeomans.

Nominating and Corporate Governance Committee: This committee recommends Board nominees, fills Board vacancies that arise in between meetings of shareholders, and considers the qualifications and independence of Board members. The committee also monitors the performance of counsel for the Independent Trustees. The committee will consider shareholder recommendations for nomination to the Board only in the event that there is a vacancy on the Board. Shareholders who wish to submit recommendations for nominations to the Board to fill a vacancy must submit their recommendations in writing to the Nominating and Corporate Governance Committee, Attention: General Counsel, c/o Delaware Funds at 2005 Market Street, Philadelphia, PA 19103-7094. Shareholders should include appropriate information on the background and qualifications of any persons recommended (e.g., a resume), as well as the candidate's contact information and a written consent from the candidate to serve if nominated and elected. Shareholder recommendations for nominations to the Board will be accepted on an ongoing basis and such recommendations will be kept on file for consideration when there is a vacancy on the Board. The committee consists of the following Independent Trustees: Frances A. Sevilla-Sacasa, Chair; Thomas L. Bennett (ex officio); Ann D. Borowiec; and Joseph W. Chow.

In reaching its determination that an individual should serve or continue to serve as a Trustee of the Trust, the committee considers, in light of the Trust's business and structure, the individual's experience, qualifications, attributes, and skills (the "Selection Factors"). No one Selection Factor is determinative, but some of the relevant factors that have been considered include: (i) the Trustee's business and professional experience and accomplishments, including prior experience in the financial services industry or on other boards; (ii) the ability to work effectively and collegially with other people; and (iii) how the Trustee's background and attributes contribute to the overall mix of skills and experience on the Board as a whole.

Independent Trustee Committee: This committee develops and recommends to the Board a set of corporate governance principles and oversees the evaluation of the Board, its committees, and its activities. The committee comprises all of the Trust's Independent Trustees.

Investments Committee: The primary purposes of the Investments Committee are to: (i) assist the Board at its request in its oversight of the investment advisory services provided to the Trust by the Manager as well as any sub-advisors; (ii) review all proposed advisory and sub-advisory agreements for new funds or proposed amendments to existing agreements and to recommend what action the full Board and the Independent Trustees should take regarding the approval of all such proposed agreements; and (iii) review reports supplied by the Manager regarding investment performance, portfolio risk and expenses and to suggest changes to such reports. The Investments Committee consists of the following Independent Trustees: Janet L. Yeomans, Chair; Jerome D. Abernathy; Ann D. Borowiec; Joseph W. Chow; and Lucinda S. Landreth.

Board role in risk oversight: The Board performs a risk oversight function for the Trust consisting, among other things, of the following activities: (1) receiving and reviewing reports related to the performance and operations of the Trust; (2) reviewing, approving, or modifying as applicable, the compliance policies and procedures of the Trust; (3) meeting with portfolio management teams to review investment strategies, techniques and the processes used to manage related risks; (4) addressing security valuation risk in connection with the Board's review of fair valuation decisions made by Fund management pursuant to Board-approved procedures; (5) meeting with representatives of key service providers, including the Manager, the Distributor, the Funds' transfer agent, the custodian and the independent public accounting firm of the Trust, to review and discuss the activities of the Trust's series, and to provide direction with respect thereto; (6) engaging the services of the Trust's Chief Compliance Officer to test the compliance procedures of the Trust and its service providers; and (7) requiring management's periodic presentations on specified risk topics.

The Trustees perform this risk oversight function throughout the year in connection with each quarterly Board meeting. The Trustees routinely discuss certain risk-management topics with Fund management at the Board level and also through the standing committees of the Board. In addition to these recurring risk-management discussions, Fund management raises other specific risk-management issues relating to the Funds with the Trustees at Board and committee meetings. When discussing new product initiatives with the Board, Fund management also discusses risk — either the risks associated with the new proposals or the risks that the proposals are designed to mitigate. Fund management also provides periodic presentations to the Board to give the Trustees a general overview of how the Manager and its affiliates identify and manage risks pertinent to the Trust.

The Audit Committee looks at specific risk-management issues on an ongoing basis. The Audit Committee is responsible for certain aspects of risk oversight relating to financial statements, the valuation of the Trust's assets, and certain compliance matters. In addition, the Audit Committee meets with the Manager's internal audit and risk-management personnel on a quarterly basis to review the reports on their examinations of functions and processes affecting the Trust.

The Board's other committees also play a role in assessing and managing risk. The Nominating and Corporate Governance Committee and the Independent Trustee Committee play a role in managing governance risk by developing and recommending to the Board corporate governance principles and, in the case of the Independent Trustee Committee, by overseeing the evaluation of the Board, its committees, and its activities. The Investments Committee plays a significant role in assessing and managing risk through the Committee's oversight of investment performance, investment process, investment risk controls, and fund expenses.

Because risk is inherent in the operation of any business endeavor, and particularly in connection with the making of financial investments, there can be no assurance that the Board's approach to risk oversight will be able to minimize or even mitigate any particular risk. The Funds are designed for investors that are prepared to accept investment risk, including the possibility that as yet unforeseen risks may emerge in the future.

Because everyone's tax situation is unique, you should consult your tax professional about federal, state, local, or foreign tax consequences before making an investment in a Fund.

Delaware Management Company (Manager) is an indirect wholly owned subsidiary of Macquarie Group Limited (MGL).

The obligations of these entities do not represent deposits or other liabilities of MBL.
