Profile: Delaware Limited-Term Government Fund

What are the Fund's goals?
Delaware Limited-Term Government Fund seeks to provide a high stable level of
income, while attempting to minimize fluctuations in principal and provide
maximum liquidity. Although the Fund will strive to meet its goals, there is no
assurance that it will.

What are the Fund's main investment strategies?
The Fund invests primarily in short- and intermediate-term U.S. government
securities. These are debt securities issued or guaranteed by the U.S., such as
U.S. Treasuries; securities issued by U.S. government agencies or
instrumentalities, such as securities of the Government National Mortgage
Association; and securities that are privately issued but are 100%
collateralized by securities or certificates issued or guaranteed by the U.S.
government, its agencies or instrumentalities. The Fund may also invest up to
20% of its net assets in corporate notes and bonds, certificates of deposit and
obligations of U.S. and foreign banks, commercial paper, certain asset-backed
securities and non-agency mortgage-backed securities.

The level of income the Fund provides will vary depending on current interest
rates and the specific securities in the portfolio. However, since longer-term
rates are generally less volatile than short-term rates, the Fund's income may
fluctuate less than a money market fund's income.

Under normal circumstances, the Fund will invest at least 80% of its net assets
in U.S. government securities ("80% policy"). This 80% policy can be changed
without shareholder approval. However, shareholders would be given at least 60
days notice prior to any such change.

What are the main risks of investing in the Fund?
Investing in any mutual fund involves risk, including the risk that you may lose
part or all of the money you invest. Over time, the value of your investment in
the Fund will increase and decrease according to changes in the value of the
securities in the Fund's portfolio. This Fund will be affected primarily by
changes in interest rates. For example, when interest rates rise, the value of
bonds in the Fund's portfolio will likely decline.

For a more complete discussion of risk, please see "The risks of investing in
the Fund" on page 9.

An investment in the Fund is not a deposit of any bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.

Who should invest in the Fund
o Investors with intermediate or long-term financial goals.
o Investors seeking monthly income.
o Investors who would like a relatively conservative income investment to
help balance a growth-oriented long-term portfolio.
o Investors seeking a high-quality investment with a measure of capital
preservation.

Who should not invest in the Fund
o Investors with very short-term financial goals.
o Investors who are unwilling to accept share prices that may fluctuate,
especially over the short term.
o Investors who want an investment with a fixed share price, such as a money
market fund.

You should keep in mind that an investment in the Fund is not a complete
investment program; it should be considered just one part of your total
financial plan. Be sure to discuss this Fund with your financial advisor to
determine whether it is an appropriate choice for you.

How has Delaware Limited-Term Government Fund performed?

This bar chart and table can help you evaluate the risks of investing in the
Fund. We show how annual returns for the Fund's Class A shares have varied over
the past ten calendar years, as well as the average annual returns of Class A,
B, C and R shares for one-year, five-year and ten-year or lifetime periods, as
applicable. The Fund's past performance (before and after taxes) is not
necessarily an indication of how it will perform in the future. The returns
reflect expense caps in effect during these periods. The returns would be lower
without the expense caps. Please see the footnotes on page 4 for additional
information about the expense caps.

During the periods illustrated in this bar chart, Class A's highest quarterly
return was 4.49% for the quarter ended December 31, 1998 and its lowest
quarterly return was - 1.33% for the quarter ended June 30, 2004.

The maximum Class A sales charge of 2.75%, which is normally deducted when you
purchase shares, is not reflected in the previous paragraph or in the bar chart.
If this fee were included, the returns would be less than those shown. The
average annual returns in the table below do include the sales charge.

The Fund's returns above are compared to the performance of the Merrill Lynch
1-3 Year U.S. Treasury Index. You should remember that, unlike the Fund, the
index is unmanaged and does not reflect the actual costs of operating a mutual
fund, such as the costs of buying, selling and holding securities. Maximum sales
charges are included in the Fund returns shown above.

After-tax performance is presented only for Class A shares of the Fund. The
after-tax returns for other Fund classes may vary. Actual after-tax returns
depend on the investor's individual tax situation and may differ from the
returns shown. After-tax returns are not relevant for shares held in
tax-deferred investment vehicles such as employer-sponsored 401(k) plans and
individual retirement accounts. The after-tax returns shown are calculated using
the highest individual federal marginal income tax rates in effect during the
Fund's lifetime and do not reflect the impact of state and local taxes. The
after-tax rate used is based on the current tax characterization of the elements
of the Fund's returns (e.g., qualified vs. non-qualified dividends) and may be
different than the final tax characterization of such elements. Past
performance, both before and after taxes, is not a guarantee of future results.

* Total returns assume redemption of shares at end of period. Lifetime
returns for Class B shares reflect conversion to Class A shares after 5
years. If shares were not redeemed, the returns for Class B would be 0.90%,
3.36% and 4.26% for the one-year, five-year and ten-year periods,
respectively. If shares were not redeemed, the returns for Class C would be
0.90%, 3.36% and 3.82% for the one-year, five-year and ten-year periods,
respectively.
** Lifetime returns are shown if the Fund or Class existed for less than 10
years. The inception date for the Class R shares of the Fund was June 2,
2003. The Merrill Lynch 1-3 Year U.S. Treasury Index returns shown are for
the ten-year period. The Merrill Lynch 1-3 year U.S. Treasury Index reports
returns on a monthly basis. The index returns for the Class R lifetime
period was 1.26%. The index return for Class R

lifetime reflects the return from June 30, 2003 through December 31, 2005.

(1) A purchase of Class A shares of $1 million or more may be made at net asset
value. However, if you buy the shares through a financial advisor who is
paid a commission, a contingent deferred sales charge will apply to
redemptions made within two years of purchase. Additional Class A purchase
options that involve a contingent deferred sales charge may be permitted
from time to time and will be disclosed in the Prospectus if they are
available.
(2) If you redeem Class B shares during the first year after you buy them, you
will pay a contingent deferred sales charge of 2.00%, which declines to
1.00% during the second and third years and 0% thereafter.
(3) Class C shares redeemed within one year of purchase are subject to a 1.00%
contingent deferred sales charge.

(4) The Fund's Distributor has contracted to limit the Class A and Class R
shares' 12b-1 fees through April 30, 2007 to no more than 0.15% and 0.50%,
respectively, of average daily net assets.
(5) "Other expenses" have been restated to reflect an expected decrease during
the current fiscal year because the Fund is not expected to convene a
shareholders' meeting and issue a proxy statement during the current fiscal
year.
(6) The investment manager has contracted to waive fees and pay expenses
through April 30, 2007 in order to prevent total operating expenses
(excluding any 12b-1 fees, taxes, interest, brokerage fees, extraordinary
expenses and certain insurance costs) from exceeding 0.65% of average daily
net assets.
(7) The Fund's actual rate of return may be greater or less than the
hypothetical 5% return we use here.
(8) The Class B example reflects the conversion of Class B shares to Class A
shares after five years. Information for years six through 10 reflects
expenses of the Class A shares.

How we manage the Fund

Our investment strategies
We analyze economic and market conditions, seeking to identify the securities or
market sectors that we believe are the best investments for the Fund. Following
are descriptions of how the portfolio management team pursues the Fund's
investment goals.

We take a disciplined approach to investing, combining investment strategies and
risk management techniques that can help shareholders meet their goals.

We invest primarily in short- and intermediate-term fixed income securities including:

o securities issued or guaranteed by the U.S. government, such as U.S.
Treasuries; and
o securities issued by U.S. government agencies or instrumentalities, such as
securities of the Government National Mortgage Association.

We may invest in instruments that use these government securities as collateral.
We may invest up to 20% of the Fund's net assets in corporate notes and bonds,
certificates of deposit and obligations of both U.S. and foreign banks,
commercial paper, certain asset-backed securities and non-agency mortgage-backed
securities.

The Fund's level of income and the stability of its share price will be directly
affected by changes in short- and intermediate-term interest rates. We
anticipate that the level of income could be higher than a money market fund.
However, the Fund's share price will increase and decrease with changes in
interest rates. This makes its risk level greater than that of a money market
fund.

We strive to reduce the effects of interest rate changes on the share price by
maintaining an average effective duration of two to three years. The average
effective duration is determined by averaging the individual effective duration
of all securities in the portfolio. If we believe that interest rates are
historically low, we may shorten the average effective duration to two years.
Conversely, if we believe rates are high and therefore likely to go lower, we
may increase average effective duration to as high as three years.

The Fund's investment objectives are non-fundamental. This means that the Board
of Trustees may change the Fund's objectives without obtaining shareholder
approval. If the objectives were changed, we would notify shareholders before
the change in the objectives became effective.

The securities we typically invest in

stocks, and also may provide capital appreciation.

In a credit default swap, a fund may
transfer the financial risk of a
credit event occurring (a bond
default, bankruptcy, restructuring,
etc.) on a particular security or
basket of securities to another party
by paying that party a periodic
premium; likewise, a fund may assume
the financial risk of a credit event
occurring on a particular security or
basket of securities in exchange for
receiving premium payments from
another party. Interest rate swaps,
index swaps and credit default swaps
may be considered to be illiquid.
--------------------------------------- ----------------------------------

The Fund may also invest in other securities, including certificates of deposit
and obligations of both U.S. and foreign banks; and corporate debt and
commercial paper. Please see the Statement of Additional Information (SAI) for
additional descriptions of these securities as well as those listed in the table
above.

Borrowing from banks
The Fund may borrow money from banks as a temporary measure for extraordinary or
emergency purposes or to facilitate redemptions. The Fund will be required to
pay interest to the lending banks on the amounts borrowed. As a result,
borrowing money could result in the Fund being unable to meet its investment
objectives. The Fund will not borrow money in excess of one-third of the value
of its net assets.

Lending securities
The Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for their use in securities transactions. Borrowers of
the Fund's securities must provide collateral to the Fund and adjust the amount
of collateral each day to reflect changes in the value of the loaned securities.
These transactions may generate additional income for the Fund.

Purchasing securities on a when-issued or delayed delivery basis
The Fund may buy or sell securities on a when-issued or delayed delivery basis;
that is, paying for securities before delivery or taking delivery at a later
date. The Fund will designate cash or securities in amounts sufficient to cover
its obligations, and will value the designated assets daily.

Portfolio turnover
We anticipate that the Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if, for example, the Fund bought and
sold all of the securities in its portfolio once in the course of a year or
frequently traded a single security. A high rate of portfolio turnover in any
year may increase brokerage commissions paid and could generate taxes for
shareholders on realized investment gains.

The risks of investing in the Fund
Investing in any mutual fund involves risk, including the risk that you may
receive little or no return on your investment, and the risk that you may lose
part or all of the money you invest. Before you invest in the Fund, you should
carefully evaluate the risks. Because of the nature of the Fund, you should
consider your investment to be a long-term investment that typically provides
the best results when held for a number of years. The table below describes the
chief risks you assume when investing in the Fund. Please see the SAI for a
further discussion of these risks and other risks not discussed here.

Shareholders

Board of Trustees A mutual fund is governed by a board of trustees which has
oversight responsibility for the management of the fund's business affairs.
Trustees establish procedures and oversee and review the performance of the
investment manager, the distributor and others that perform services for the
fund. Generally, at least 40% of the board of trustees must be independent of a
fund's investment manager and distributor. However, the Fund relies on certain
exemptive rules adopted by the SEC that require its Board of Trustees to be
comprised of a majority of such independent Trustees. These independent
Trustees, in particular, are advocates for shareholder interests.

Investment manager An investment manager is a company responsible for selecting
portfolio investments consistent with the objective and policies stated in the
mutual fund's prospectus. The investment manager places portfolio orders with
broker/dealers and is responsible for obtaining the best overall execution of
those orders. A written contract between a mutual fund and its investment
manager specifies the services the manager performs. Most management contracts
provide for the manager to receive an annual fee based on a percentage of the
fund's average daily net assets. The manager is subject to numerous legal
restrictions, especially regarding transactions between itself and the funds it
advises.

Portfolio managers Portfolio managers are employed by the investment manager to
make investment decisions for individual portfolios on a day-to-day basis.

Custodian Mutual funds are legally required to protect their portfolio
securities and most funds place them with a qualified bank custodian who
segregates fund securities from other bank assets.

Distributor Most mutual funds continuously offer new shares to the public
through distributors who are regulated as broker/dealers and are subject to NASD
rules governing mutual fund sales practices.

Financial intermediary wholesaler Pursuant to a contractual arrangement with
Delaware Distributors, L.P., Lincoln Financial Distributors, Inc. (LFD) is
primarily responsible for promoting the sale of fund shares through
broker/dealers, financial advisors and other financial intermediaries.

Service agent Mutual fund companies employ service agents (sometimes called
transfer agents) to maintain records of shareholder accounts, calculate and
disburse dividends and capital gains and prepare and mail shareholder statements
and tax information, among other functions. Many service agents also provide
customer service to shareholders.

Financial advisors Financial advisors provide advice to their clients, analyzing
their financial objectives and recommending appropriate funds or other
investments. Financial advisors are associated with securities broker/dealers
who have entered into selling and/or service arrangements with the distributor.
Selling broker/dealers and financial advisors are compensated for their
services, generally through sales commissions, and through 12b-1 fees and/or
service fees deducted from the fund's assets.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights. Material changes in the terms of a fund's management
contract must be approved by a shareholder vote, and funds seeking to change
fundamental investment policies must also seek shareholder approval.

About your account

Investing in the Fund
You can choose from a number of share classes for the Fund. Because each share
class has a different combination of sales charges, fees and other features, you
should consult your financial advisor to determine which class best suits your
investment goals and time frame.

Choosing a share class

CLASS A
o Class A shares have an up-front sales charge of up to 2.75% that you pay
when you buy the shares.

o If you invest $100,000 or more, your front-end sales charge will be
reduced.

o You may qualify for other reductions in sales charges, and, under certain
circumstances, the sales charge may be waived; as described in "How to
reduce your sales charge," below.

o Class A shares are also subject to an annual 12b-1 fee no greater than
0.30% (currently limited to 0.15%) of average daily net assets, which is
lower than the 12b-1 fee for Class B, Class C and Class R shares. See
"Dealer compensation" below for further information.

o Class A shares generally are not subject to a contingent deferred sales
charge except in the limited circumstances described in the table below.

o Class A shares generally are not available for purchase by anyone qualified
to purchase Class R shares, except as described below.

Class A sales charges
The table below details your sales charges on purchases of Class A shares. The
offering price for Class A shares includes the front-end sales charge. The sales
charge as a percentage of the net amount invested is the maximum percentage of
the amount invested rounded to the nearest hundredth. The actual sales charge
that you pay as a percentage of the offering price and as a percentage of the
net amount invested will vary depending on the then-current net asset value, the
percentage rate of sales charge and rounding.

----------------------------- ----------------------------------- -------------------------------
Sales charge as % of net amount
Amount of purchase Sales charge as % of offering price invested
--------------------------------------------------------------------------------------------------
Less than $100,000 2.75% 3.23%
--------------------------------------------------------------------------------------------------
$100,000 but under $250,000 2.00% 2.44%
--------------------------------------------------------------------------------------------------
$250,000 but under $1 million 1.00% 1.34%-
--------------------------------------------------------------------------------------------------
$1 million or more None (Limited CDSC may apply)* None (Limited CDSC may apply)*
--------------------------------------------------------------------------------------------------

* There is no front-end sales charge when you purchase $1 million or more of
Class A shares. However, if the Fund's Distributor paid your financial advisor a
commission on your purchase of $1 million or more of Class A shares, you will
have to pay a limited contingent deferred sales charge (Limited CDSC) of 0.75%
if you redeem these shares within the first year, unless a specific waiver of
the charge applies. The Limited CDSC will be paid to the Distributor and will be
assessed on an amount equal to the lesser of: (1) the net asset value at the
time of purchase of the Class A shares being redeemed; or (2) the net asset
value of such Class A shares at the time of redemption. For purposes of this
formula, the "net asset value at the time of purchase" will be the net asset
value at purchase of the Class A shares even if those shares are later exchanged
for shares of another Delaware Investments(R)Fund and, in the event of an
exchange of Class A shares, the "net asset value of such shares at the time of
redemption" will be the net asset value of the shares acquired in the exchange.
In determining whether a Limited CDSC is payable, it will be assumed that shares
not subject to the Limited CDSC are the first redeemed followed by other shares
held for the longest period of time. See "Dealer compensation" below for a
description of the dealer commission that is paid.

CLASS B
o Class B shares have no up-front sales charge, so the full amount of your
purchase is invested in the Fund. However, you will pay a contingent
deferred sales charge if you redeem your shares within three years after
you buy them.

o If you redeem Class B shares during the first year after you buy them, the
shares will be subject to a contingent deferred sales charge of 2.00%. The
contingent deferred sales charge is 1.00% during the second and third years
and 0% thereafter.

o In determining whether the contingent deferred sales charge applies to a
redemption of Class B Shares, it will be assumed that shares held for more
than three years are redeemed first, followed by shares acquired through
the reinvestment of dividends or distributions, and finally by shares held
longest during the three-year period. For further information on how the
contingent deferred sales charge is determined, please see "Calculation of
Contingent Deferred Sales Charges-- Class B and Class C" below.

o Under certain circumstances the contingent deferred sales charge may be
waived; please see "Waivers of Contingent Deferred Sales Charges" below for
further information.

o For approximately five years after you buy your Class B shares, they are
subject to annual 12b-1 fees no greater than 1.00% of average daily net
assets (of which 0.25% are service fees) paid to the Distributor, dealers
or others for providing services and maintaining shareholder accounts.

o Because of the higher 12b-1 fees, Class B shares have higher expenses and
any dividends paid on these shares are generally lower than dividends on
Class A and Class R shares.

o Approximately five years after you buy them, Class B shares automatically
convert into Class A shares with a 12b-1 fee of no more than 0.30%.
Conversion may occur as late as three months after the fifth anniversary of
purchase, during which time Class B's higher 12b-1 fees apply.

o You may purchase only up to $100,000 of Class B shares at any one time. The
limitation on maximum purchases varies for retirement plans.

CLASS C
o Class C shares have no up-front sales charge, so the full amount of your
purchase is invested in the Fund. However, you will pay a contingent
deferred sales charge of 1.00% if you redeem your shares within 12 months
after you buy them.

o In determining whether the contingent deferred sales charge applies to a
redemption of Class C shares, it will be assumed that shares held for more
than 12 months are redeemed first followed by shares acquired through the
reinvestment of dividends or distributions, and finally by shares held for
12 months or less. For further information on how the contingent deferred
sales charge is determined, please see "Calculation of Contingent Deferred
Sales Charges - Class B and Class C" below.

o Under certain circumstances the contingent deferred sales charge may be
waived; please see "Waivers of Contingent Deferred Sales Charges" below for
further information.

o Class C shares are subject to an annual 12b-1 fee no greater than 1.00% of
average daily net assets, (of which 0.25% are service fees) paid to the
Distributor, dealers or others for providing services and maintaining
shareholder accounts.

o Because of the higher 12b-1 fees, Class C shares have higher expenses and
any dividends paid on these shares are generally lower than dividends on
Class A and Class R shares.

o Unlike Class B shares, Class C shares do not automatically convert into
another class.

o You may purchase any amount less than $1,000,000 of Class C shares at any
one time. The limitation on maximum purchases varies for retirement plans.

CLASS R
o Class R shares have no up-front sales charge, so the full amount of your
purchase is invested in the Fund. Class R shares are not subject to a
contingent deferred sales charge.

o Class R shares are subject to an annual 12b-1 fee no greater than 0.60%
(currently limited to 0.50%) of average daily net assets, which is lower
than the 12b-1 fee for Class B and Class C shares.

o Because of the higher 12b-1 fee, Class R shares have higher expenses and
any dividends paid on these shares are generally lower than dividends on
Class A shares.

o Unlike Class B shares, Class R shares do not automatically convert into
another class.

o Class R shares generally are available only to: (i) qualified and
non-qualified plan shareholders covering multiple employees (including
401(k), 401(a), 457 and non-custodial 403(b) plans, as well as other
non-qualified deferred compensation plans) with assets at the time shares
are considered for purchase of $10 million or less; and (ii) to IRA
rollovers from plans maintained on the Delaware Investments(R)retirement
recordkeeping system or BISYS's retirement recordkeeping system that are
offering Class R shares to participants.

Except as noted above, no other IRA accounts are eligible for Class R shares
(e.g., no SIMPLE IRA's, SEP/IRA's, SAR/SEP IRA's, Roth IRA's, etc.). For
purposes of determining plan asset levels, affiliated plans may be combined at
the request of the plan sponsor.

Any account holding Class A shares as of June 2, 2003 (the date Class R shares
were made available) continues to be eligible to purchase Class A shares after
that date. Any account holding Class R shares is not eligible to purchase Class
A shares.

Each share class may be eligible for purchase through programs sponsored by
financial intermediaries that require the purchase of a specific class of
shares.

Each share class of the Fund has adopted a separate 12b-1 plan that allows it to
pay distribution fees for the sale and distribution of its shares. Because these
fees are paid out of the Fund's assets on an ongoing basis, over time these fees
will increase the cost of your investment and may cost you more than paying
other types of sales charges.

Calculation of Contingent Deferred Sales Charges - Class B and Class C
Contingent deferred sales charges are charged as a percentage of the dollar
amount subject to the contingent deferred sales charge. The charge will be
assessed on an amount equal to the lesser of the net asset value at the time of
the shares being redeemed or the net asset value of those shares at the time of
redemption. No contingent deferred sales charge will be imposed on increases in
net asset value above the initial purchase price, nor will a contingent deferred
sales charge be assessed on redemptions of shares acquired through reinvestment
of dividends or capital gains distributions. For purposes of this formula, the
"net asset value at the time of purchase" will be the net asset value at
purchase of Class B Shares or Class C Shares of a Fund, even if those shares are
later exchanged for shares of another Delaware Investments(R)Fund. In the event
of an exchange of the shares, the "net asset value of such shares at the time of
redemption" will be the net asset value of the shares that were acquired in the
exchange.

Dealer compensation

The financial advisor that sells you shares of the Fund may be eligible to
receive the following amounts as compensation for your investment in the Fund.
These amounts are paid by the Distributor to the securities dealer with whom
your financial advisor is associated.

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

(1) On sales of Class A shares, the Distributor re-allows to your securities
dealer a portion of the front-end sales charge depending upon the amount
you invested. The maximum 12b-1 fee applicable to Class A shares is 0.30%
of average daily net assets. However, the Distributor has contracted to
limit this amount to 0.15% through April 30, 2007. Your securities dealer
is eligible to receive the maximum annual 12b-1 fee applicable to Class A
shares of up to 0.30% of average daily net assets, although this rate is
currently 0.15%.

(2) On sales of Class B shares, the Distributor pays your securities dealer an
up-front commission of 2.00%. After approximately eight years, Class B
shares automatically convert into Class A shares and dealers may then be
eligible to receive the 0.30% 12b-1 fee applicable to Class A.

(3) On sales of Class C shares, the Distributor pays your securities dealer an
up-front commission of 1.00%. The up-front commission includes an advance
of the first year's 12b-1 service fee of up to 0.25%. During the first 12
months, the Distributor retains the full 1.00% 12b-1 fee to partially
offset the up-front commission and the prepaid 0.25% service fee advanced
at the time of purchase. Starting in the 13th month, your securities dealer
may be eligible to receive the full 1.00% 12b-1 fee applicable to Class C.

(4) On sales of Class R shares, the Distributor does not pay your securities
dealer an up-front commission. The maximum 12b-1 fee applicable to Class R
shares is 0.60% of average daily net assets. However, the Distributor has
contracted to limit this amount to 0.50% through April 30, 2007. Your
securities dealer may be eligible to receive a 12b-1 fee of up to 0.60%
from the date of purchase, although this rate is currently 0.50%.

How to reduce your sales charge
We offer a number of ways to reduce or eliminate the sales charge on shares.
Please refer to the SAI for detailed information and eligibility requirements.
You can also get additional information from your financial advisor. You or your
financial advisor must notify us at the time you purchase shares if you are
eligible for any of these programs. You may also need to provide information to
your financial advisor or the Fund in order to qualify for a reduction in sales
charges. Such information may include your Delaware Investments(R)Funds holdings
in any other account, including retirement accounts held indirectly or through
an intermediary and the names of qualifying family members and their holdings.
Class R shares have no sales charge. We reserve the right to determine whether
any purchase is entitled, by virtue of the foregoing, to the reduced sales
charge.

maintain any records that substantiate these costs because the Fund, its
transfer agent and financial intermediaries may not maintain this information.
Information about existing sales charges and sales charge reductions and waivers
is available free of charge in a clear and prominent format on the Delaware
Investments(R)Funds' Web site at www.delawareinvestments.com. Additional
information on sales charges can be found in the SAI.

How to buy shares

[GRAPHIC OMITTED: SYMBOL OF A PERSON]

Through your financial advisor
Your financial advisor can handle all the details of purchasing shares,
including opening an account. Your financial advisor may charge a separate fee
for this service.

[GRAPHIC OMITTED: SYMBOL OF AN ENVELOPE]

By mail
Complete an investment slip and mail it with your check, made payable to the
fund and class of shares you wish to purchase, to Delaware Investments, 2005
Market Street, Philadelphia, PA 19103-7094. If you are making an initial
purchase by mail, you must include a completed investment application (or an
appropriate retirement plan application if you are opening a retirement account)
with your check.

[GRAPHIC OMITTED: SYMBOL OF A JAGGED LINE]

By wire
Ask your bank to wire the amount you want to invest to Bank of New York, ABA
#021000018, Bank Account number 8900403748. Include your account number and the
name of the fund and class of shares in which you want to invest. If you are
making an initial purchase by wire, you must first call us at 800 523-1918 so we
can assign you an account number.

[GRAPHIC OMITTED: EXCHANGE SYMBOL]

By exchange
You may exchange all or part of your investment in one or more Delaware
Investments(R)Funds for shares of other Delaware Investments(R)Funds. Please
keep in mind, however, that under most circumstances you are allowed to exchange
only between like classes of shares. To open an account by exchange, call the
Shareholder Service Center at 800 523-1918.

[GRAPHIC OMITTED: SYMBOL OF A KEYPAD]

Through automated shareholder services
You may purchase or exchange shares through Delaphone, our automated telephone
service, or through our Web site, www.delawareinvestments.com. For more
information about how to sign up for these services, call our Shareholder
Service Center at 800 523-1918.

Once you have completed an application, you can open an account with an initial
investment of $1,000 and make additional investments at any time for as little
as $100. The minimum initial purchase is $250, and you can make additional
investments of only $25, if you are buying shares in an IRA or Roth IRA, under
the Uniform Gifts to Minors Act or the Uniform Transfers to Minors Act, or
through an Automatic Investing Plan. The minimum purchase for a Coverdell
Education Savings Account (formerly an "Education IRA") is $500. The minimums
vary for retirement plans other than IRAs, Roth IRAs or Coverdell Education
Savings Accounts.

The price you pay for shares will depend on when we receive your purchase order.
If we or an authorized agent receive your order before the close of regular
trading on the New York Stock Exchange (NYSE), which is normally 4:00 p.m.
Eastern Time, you will pay that day's closing share price, which is based on the
Fund's net asset value (NAV). If your order is received after the close of
regular trading on the NYSE, you will pay the next business day's price. A
business day is any day that the NYSE is open for business (Business Day). We
reserve the right to reject any purchase order.

We price fixed-income securities on the basis of valuations provided to us by an
independent pricing service that uses methods approved by the Board of Trustees.
We price any fixed-income securities that have a maturity of less than 60 days
at amortized cost, which approximates market value. For all other securities, we
use methods approved by the Board of Trustees that are designed to price
securities at their fair market value.

Fair valuation
When the Fund uses fair value pricing, it may take into account any factors it
deems appropriate. The Fund may determine fair value based upon developments
related to a specific security, current valuations of foreign stock indices (as
reflected in U.S. futures markets) and/or U.S. sector or broader stock market
indices. The price of securities used by the Fund to calculate its NAV may
differ from quoted or published prices for the same securities. Fair value
pricing may involve subjective judgments and it is possible that the fair value
determined for a security is materially different than the value that could be
realized upon the sale of that security.

The Fund anticipates using fair value pricing for securities primarily traded on
U.S. exchanges only under very limited circumstances, such as the early closing
of the exchange on which a security is traded or suspension of trading in the
security. The Fund may use fair value pricing more frequently for securities
primarily traded in non-U.S. markets because, among other things, most foreign
markets close well before the Fund values its securities at 4:00 p.m. Eastern
Time. The earlier close of these foreign markets gives rise to the possibility
that significant events, including broad market moves, may have occurred in the
interim. To account for this, the Fund may frequently value many foreign equity
securities using fair value prices based on third party vendor modeling tools to
the extent available.

Subject to the Board's oversight, the Fund's Board has delegated responsibility
for valuing the Fund's assets to a Pricing Committee of the Manager, which
operates under the policies and procedures approved by the Board as described
above.

Retirement plans
In addition to being an appropriate investment for your IRA, Roth IRA and
Coverdell Education Savings Account, shares in the Fund may be suitable for
group retirement plans. You may establish your IRA account even if you are
already a participant in an employer-sponsored retirement plan. For more
information on how shares in the Fund can play an important role in your
retirement planning or for details about group plans, please consult your
financial advisor, or call 800 523-1918.

Document delivery
If you have an account in the same Delaware Investments(R)Fund as another member
of your household, we are sending your household one copy of the Fund's
prospectus and annual and semiannual reports unless you opt otherwise. This will
help us reduce the printing and mailing expenses associated with the Fund. We
will continue to send one copy of each of these documents to your household
until you notify us that you wish individual materials. If you wish to receive
individual materials, please call our Shareholder Service Center at 800 523-1918
or your financial advisor. We will begin sending you individual copies of these

How to redeem shares

[GRAPHIC OMITTED: SYMBOL OF A PERSON]

Through your financial advisor
Your financial advisor can handle all the details of redeeming your shares
(selling them back to the Fund). Your financial advisor may charge a separate
fee for this service.

[GRAPHIC OMITTED: SYMBOL OF AN ENVELOPE]

By mail
You may redeem your shares by mail by writing to: Delaware Investments, 2005
Market Street, Philadelphia, PA 19103-7094. All owners of the account must sign
the request, and for redemptions of more than $100,000, you must include a
signature guarantee for each owner. Signature guarantees are also required when
redemption proceeds are going to an address other than the address of record on
the account.

[GRAPHIC OMITTED: SYMBOL OF A TELEPHONE]

By telephone
You may redeem up to $100,000 of your shares by telephone. You may have the
proceeds sent to you by check, or, if you redeem at least $1,000 of shares, you
may have the proceeds sent directly to your bank by wire. Bank information must
be on file before you request a wire redemption.

[GRAPHIC OMITTED: SYMBOL OF A JAGGED LINE]

By wire
You may redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account, normally the next Business Day after we receive
your request. If you request a wire deposit, a bank wire fee may be deducted
from your proceeds. Bank information must be on file before you request a wire
redemption.

[GRAPHIC OMITTED: SYMBOL OF A KEYPAD]

Through automated shareholder services
You may redeem shares through Delaphone, our automated telephone service, or
through our Web site, www.delawareinvestments.com. For more information about
how to sign up for these services, call our Shareholder Service Center at 800
523-1918.

[GRAPHIC OMITTED: SYMBOL OF A HAND HOLDING A PEN]

Through checkwriting
You may redeem Class A shares by writing checks of $500 or more. Checks must be
signed by all owners of the account unless you indicate otherwise on your
Investment Application. The checkwriting feature is not available for retirement
plans. Also, because dividends Fare declared daily, you may not close your
account by writing a check. When you write checks you are subject to bank
regulations and may be subject to a charge if the check amount exceeds the value
of your account.

If you hold your shares in certificates, you must submit the certificates with
your request to sell the shares. We recommend that you send your certificates by
certified mail.

When you send us a properly completed request to redeem or exchange shares and
we or an authorized agent receive the request before the close of regular
trading on the NYSE (normally 4:00 p.m. Eastern Time), you will receive the NAV
as next determined after we receive your request. If we receive your request
after the close of regular trading on the NYSE, you will receive the NAV next
determined on the next Business Day. We will deduct any applicable contingent
deferred sales charges. You may also have to pay taxes on the proceeds from your
sale of shares. We will send you a check, normally the next Business Day, but no
later than seven days after we receive

your request to sell your shares. If you purchased your shares by check, we will
wait until your check has cleared, which can take up to 15 days, before we send
your redemption proceeds.

If you are required to pay a contingent deferred sales charge when you redeem
your shares, the amount subject to the fee will be based on the shares' NAV when
you purchased them or their NAV when you redeem them, whichever is less. This
arrangement assures that you will not pay a contingent deferred sales charge on
any increase in the value of your shares. You also will not pay the charge on
any shares acquired by reinvesting dividends or capital gains. If you exchange
shares of one fund for shares of another, you do not pay a contingent deferred
sales charge at the time of the exchange. If you later redeem those shares, the
purchase price for purposes of the contingent deferred sales charge formula will
be the price you paid for the original shares, not the exchange price. The
redemption price for purposes of this formula will be the NAV of the shares you
are actually redeeming.

Account minimums
If you redeem shares and your account balance falls below the Fund's required
account minimum of $1,000 ($250 for IRAs, Roth IRAs, Uniform Gifts to Minors Act
and Uniform Transfers to Minors Act accounts or accounts with automatic
investing plans, and $500 for Coverdell Education Savings Accounts) for three or
more consecutive months, you will have until the end of the current calendar
quarter to raise the balance to the minimum. If your account is not at the
minimum by the required time, you will be charged a $9 fee for that quarter and
each quarter after that until your account reaches the minimum balance. If your
account does not reach the minimum balance, the Fund may redeem your account
after 60 days' written notice to you.

Special services
To help make investing with us as easy as possible, and to help you build your
investments, we offer the following special services.

Automatic Investing Plan
The Automatic Investing Plan allows you to make regular monthly or quarterly
investments directly from your checking account.

Direct Deposit
With Direct Deposit you can make additional investments through payroll
deductions, recurring government or private payments such as Social Security or
direct transfers from your bank account.

Electronic Delivery
With Delaware eDelivery, you can receive your fund documents electronically
instead of via U.S. mail. When you sign up for eDelivery, you can access your
account statements, shareholder reports and other fund materials online, in a
secure internet environment, at any time, from anywhere.

Online Account Access
Online Account Access is a password-protected area of the Delaware
Investments(R)Web site that gives you access to your account information and
allows you to perform transactions in a secure internet environment.

Wealth Builder Option
With the Wealth Builder Option you can arrange automatic monthly exchanges
between your shares in one or more Delaware Investments(R)Funds. Wealth Builder
exchanges are subject to the same rules as regular exchanges (see below) and
require a minimum monthly exchange of $100 per fund.

Dividend Reinvestment Plan
Through our Dividend Reinvestment Plan, you can have your distributions
reinvested in your account or the same share class in another Delaware
Investments(R)Fund. The shares that you purchase through the Dividend
Reinvestment Plan are not subject to a front-end sales charge or to a contingent
deferred sales charge. Under most circumstances, you may reinvest dividends only
into like classes of shares.

Exchanges
You may generally exchange all or part of your shares for shares of the same
class in another Delaware Investments(R)Fund without paying a front-end sales
charge or a contingent deferred sales charge at the time of the exchange.
However, if you exchange shares from a money market fund that does not have a
sales charge or from Class R shares of any fund, you will pay any applicable
sales charge on your new shares. When exchanging Class B and Class C shares of
one fund for the same class of shares in other funds, your new shares will be
subject to the same contingent deferred sales charge as the shares you
originally purchased. The holding period for the contingent deferred sales
charge will also remain the same, with the amount of time you held your original
shares being credited toward the holding period of your new shares. You do not
pay sales charges on shares that you acquired through the reinvestment of
dividends. You may have to pay taxes on your exchange. When you exchange shares,
you are purchasing shares in another fund so you should be sure to get a copy of
the fund's prospectus and read it carefully before buying shares through an
exchange. We may refuse the purchase side of any exchange request, if, in the
Manager's judgment, the Fund would be unable to invest effectively in accordance
with its investment objectives and policies or would otherwise potentially be
adversely affected.

MoneyLine(SM) On Demand Service
Through our MoneyLine(SM) On Demand Service, you or your financial advisor may
transfer money between your Fund account and your predesignated bank account by
telephone request. This service is not available for retirement plans. MoneyLine
has a minimum transfer of $25 and a maximum transfer of $50,000, except for
purchases into IRAs. Delaware Investments does not charge a fee for this
service; however, your bank may assess one.

MoneyLine Direct Deposit Service
Through our MoneyLine Direct Deposit Service you can have $25 or more in
dividends and distributions deposited directly to your bank account. Delaware
Investments does not charge a fee for this service; however, your bank may
assess one. This service is not available for retirement plans.

Systematic Withdrawal Plan
Through our Systematic Withdrawal Plan, you can arrange a regular monthly or
quarterly payment from your account made to you or someone you designate. If the
value of your account is $5,000 or more, you can make withdrawals of at least
$25 monthly, or $75 quarterly. You may also have your withdrawals deposited
directly to your bank account through our MoneyLine Direct Deposit Service.

The applicable limited contingent deferred sales charge for Class A Shares and
the contingent deferred sales charge for Class B and C Shares redeemed via a
Systematic Withdrawal Plan will be waived if the annual amount withdrawn in each
year is less than 12% of the account balance on the date that the Plan is
established. If the annual amount withdrawn in any year exceeds 12% of the
account balance on the date that the Systematic Withdrawal Plan is established,
all redemptions under the Plan will be subjected to the applicable contingent
deferred sales charge, including an assessment for previously redeemed amounts
under the Plan.

Frequent trading of Fund shares
The Fund discourages purchases by market timers and purchase orders (including
the purchase side of exchange orders) by shareholders identified as market
timers may be rejected. The Fund's Board of Trustees has adopted policies and
procedures designed to detect, deter and prevent trading activity detrimental to
the Fund and its shareholders, such as market timing. The Fund will consider
anyone who follows a pattern of market timing in any Delaware Investments(R)Fund
or the Optimum Fund Trust to be a market timer and may consider anyone who has
followed a similar pattern of market timing at an unaffiliated fund family to be
a market timer.

Market timing of a fund occurs when investors make consecutive, rapid,
short-term "roundtrips" -- that is, purchases into a fund followed quickly by
redemptions out of that fund. A short-term roundtrip is any redemption of fund
shares within 20 business days of a purchase of that fund's shares. If you make
a second such short-term roundtrip in a fund within the same calendar quarter as
a previous short-term roundtrip in that fund, you may be considered a market
timer. In determining whether market timing has occurred, the Fund will consider
short-term roundtrips to include rapid purchases and sales of Fund shares
through the exchange privilege. The Fund reserves the right to consider other
trading patterns to be market timing.

Your ability to use the Fund's exchange privilege may be limited if you are
identified as a market timer. If you are identified as a market timer, we will
execute the redemption side of your exchange order but may refuse the purchase
side of your exchange order. The Fund reserves the right to restrict or reject,
without prior notice, any purchase order or exchange order for any reason,
including any purchase order or exchange order accepted by any shareholder's
financial intermediary or in any omnibus-type account. Transactions placed in
violation of the Fund's market timing policy are not necessarily deemed accepted
by the Fund and may be rejected by the Fund on the next business day following
receipt by the Fund.

Redemptions will continue to be permitted in accordance with the Fund's current
Prospectus. A redemption of shares under these circumstances could be costly to
a shareholder if, for example, the shares have declined in value, the
shareholder recently paid a front-end sales charge, the shares are subject to a
contingent deferred sales charge or the sale results in adverse tax
consequences. To avoid this risk, a shareholder should carefully monitor the
purchases, sales and exchanges of Fund shares and avoid frequent trading in Fund
shares.

The Fund reserves the right to modify this policy at any time without notice,
including modifications to the Fund's monitoring procedures and the procedures
to close accounts to new purchases. Although the implementation of this policy
involves judgments that are inherently subjective, we seek to apply this policy
uniformly in all cases and make judgments and applications that are consistent
with the interests of the Fund's shareholders. While we will take actions
designed to detect and prevent market timing, there can be no assurance that
such trading activity will be completely eliminated.

portfolio management. In particular, the Fund may have difficulty implementing
its long-term investment strategies if it is forced to maintain a higher level
of its assets in cash to accommodate significant short-term trading activity.
Excessive purchases and sales or exchanges of the Fund's shares may also force
the Fund to sell portfolio securities at inopportune times to raise cash to
accommodate short-term trading activity. This could adversely affect the Fund's
performance if, for example, the Fund incurs increased brokerage costs and
realization of taxable capital gains without attaining any investment advantage.

A fund that invests significantly in foreign securities may be particularly
susceptible to short-term trading strategies. This is because foreign securities
are typically traded on markets that close well before the time the fund
calculates its NAV (typically, 4:00 p.m. Eastern Time). Developments that occur
between the closing of the foreign market and the fund's NAV calculation may
affect the value of these foreign securities. The time zone differences among
international stock markets can allow a shareholder engaging in a short-term
trading strategy to exploit differences in fund share prices that are based on
closing prices of foreign securities established some time before a fund
calculates its own share price.

Any fund that invests in securities that are thinly traded, traded infrequently
or relatively illiquid has the risk that the securities prices used to calculate
the fund's NAV may not accurately reflect current market values. A shareholder
may seek to engage in short-term trading to take advantage of these pricing
differences. Funds that may be adversely affected by such arbitrage include, in
particular, funds that significantly invest in small-cap securities, technology
and other specific industry sector securities, and in certain fixed-income
securities, such as high-yield bonds, asset-backed securities or municipal
bonds.

Transaction monitoring procedures
The Fund, through its transfer agent, maintains surveillance procedures designed
to detect excessive or short-term trading in Fund shares. This monitoring
process involves several factors, which include scrutinizing transactions in
fund shares for violations of the Fund's market timing policy or other patterns
of short-term or excessive trading. For purposes of these transaction monitoring
procedures, the Fund may consider trading activity by multiple accounts under
common ownership, control or influence to be trading by a single entity. Trading
activity identified by these factors, or as a result of any other available
information, will be evaluated to determine whether such activity might
constitute market timing. These procedures may be modified from time to time to
improve the detection of excessive or short-term trading or to address other
concerns. Such changes may be necessary or appropriate, for example, to deal
with issues specific to certain retirement plans, plan exchange limits, U.S.
Department of Labor regulations, certain automated or pre-established exchange,
asset allocation or dollar cost averaging programs, or omnibus account
arrangements.

Omnibus account arrangements are common forms of holding shares of the Fund,
particularly among certain broker/dealers and other financial intermediaries,
including sponsors of retirement plans and variable insurance products. The Fund
will attempt to apply its monitoring procedures to these omnibus accounts and to
the individual participants in such accounts. In an effort to discourage market
timers in such accounts, the Fund may consider enforcement against market timers
at the participant level and at the omnibus level, up to and including
termination of the omnibus account's authorization to purchase Fund shares.

Limitations on ability to detect and curtail market timing
Shareholders seeking to engage in market timing may employ a variety of
strategies to avoid detection and, despite the efforts of the Fund and its
agents to detect market timing in Fund shares, there is no guarantee that the
Fund will be able to identify these shareholders or curtail their trading
practices. In particular, the Fund may not be able to detect market timing
attributable to a particular investor who effects purchase, redemption and/or
exchange activity in Fund shares through omnibus accounts. The difficulty of
detecting market timing may be further compounded if these entities utilize
multiple tiers or omnibus accounts.

Dividends, distributions and taxes
Dividends and Distributions. The Fund has elected to be treated as a regulated
investment company under Subchapter M of the Internal Revenue Code. As a
regulated investment company, the Fund generally pays no federal income tax on
the income and gains it distributes to you. The Fund expects to declare
dividends daily and distribute all of its net investment income, if any, to
shareholders as dividends monthly. The Fund will also distribute net capital
gains, if any, annually. The amount of any distribution will vary, and there is
no guarantee the Fund will pay either an income dividend or a capital gain
distribution. We automatically reinvest all dividends and any capital gains,
unless you direct us to do otherwise.

Annual Statements. Every January, you will receive a statement that shows the
tax status of distributions you received the previous year. Distributions
declared in December but paid in January are taxable as if they were paid in
December. Mutual funds may reclassify income after your tax reporting statement
is mailed to you. Prior to issuing your statement, the Fund makes every effort
to search for reclassified income to reduce the number of corrected forms mailed
to shareholders. However, when necessary, the Fund will send you a corrected
Form 1099-DIV to reflect reclassified information.

Avoid "Buying A Dividend." If you invest in the Fund shortly before the record
date of a taxable distribution, the distribution will lower the value of the
Fund's shares by the amount of the distribution and, in effect, you will receive
some of your investment back in the form of a taxable distribution.

Tax Considerations. In general, if you are a taxable investor, Fund
distributions are taxable to you at either ordinary income or capital gains tax
rates. This is true whether you reinvest your distributions in additional Fund
shares or receive them in cash.

For federal income tax purposes, Fund distributions of short-term capital gains
are taxable to you as ordinary income. Fund distributions of long-term capital
gains are taxable to you as long-term capital gains no matter how long you have
owned your shares. A portion of income dividends designated by the Fund may be
qualified dividend income eligible for taxation by individual shareholders at
long-term capital gain rates provided certain holding period requirements are
met.

A sale or redemption of Fund shares is a taxable event and, accordingly, a
capital gain or loss may be recognized. For tax purposes, an exchange of your
Fund shares for shares of a different Delaware Investments(R)Fund is the same as
a sale.

By law, if you do not provide the Fund with your proper taxpayer identification
number and certain required certifications, you may be subject to backup
withholding on any distributions of income, capital gains or proceeds from the
sale of your shares. The Fund also must withhold if the IRS instructs it to do
so. When withholding is required, the amount will be 28% of any distributions or
proceeds paid.

Fund distributions and gains from the sale or exchange of your Fund shares
generally are subject to state and local taxes. Non-U.S. investors may be
subject to U.S. withholding or estate tax, and are subject to special U.S. tax
certification requirements.

This discussion of "Dividends, distributions and taxes" is not intended or
written to be used as tax advice. 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 the Fund.

Certain management considerations

Investments by fund of funds and similar investment vehicles
The Fund may accept investments from funds of funds, including those offered by
the Delaware Investments(R)Funds, as well as similar investment vehicles, such
as 529 Plans. A "529 Plan" is a college savings program that operates under
Section 529 of the Internal Revenue Code. From time to time, the Fund may
experience large investments or redemptions due to allocations or rebalancings
by these funds of funds and/or similar investment vehicles. While it is
impossible to predict the overall impact of these transactions over time, there
could be adverse effects on portfolio management. For example, the Fund may be
required to sell securities or invest cash at times when it would not otherwise
do so. These transactions could also have tax consequences if sales of
securities result in gains, and could also increase transaction costs or
portfolio turnover. The Manager will monitor transactions by the funds of funds
and will attempt to minimize any adverse effects on both the Fund and the funds
of funds as a result of these transactions.

approval but without shareholder approval (the "Manager of Managers Structure").
While the Manager does not currently expect to use the Manager of Managers
Structure with respect to the Fund, the Manager may, in the future, recommend to
the Fund's Board the establishment of the Manager of Managers Structure by
recommending the hiring of one or more sub-advisors to manage all or a portion
of the Fund's portfolio if it believes that doing so would be likely to enhance
the Fund's performance by introducing a different investment style or focus.

The ability to implement the Manager of Managers Structure with respect to the
Fund is contingent upon the receipt of an exemptive order from the U.S.
Securities and Exchange Commission (the "SEC") or the adoption of a rule by the
SEC authorizing the implementation of the Manager of Managers Structure. The use
of the Manager of Managers Structure with respect to the Fund may be subject to
certain conditions set forth in the SEC exemptive order or rule. There can be no
assurance that the SEC will grant the Fund's application for an exemptive order
or adopt such a rule.

The Manager of Managers Structure would enable the Fund to operate with greater
efficiency and without incurring the expense and delays associated with
obtaining shareholder approval of sub-advisory agreements. The Manager of
Managers Structure would not permit investment management fees paid by the Fund
to be increased without shareholder approval or change the Manager's
responsibilities to the Fund, including the Manager's responsibility for all
advisory services furnished by a sub-advisor.

How to read the financial highlights

Net investment income (loss)
Net investment income (loss) includes dividend and interest income earned from a
fund's investments; it is after expenses have been deducted.

Net realized and unrealized gain (loss) on investments
A realized gain occurs when we sell an investment at a profit, while a realized
loss occurs when we sell an investment at a loss. When an investment increases
or decreases in value but we do not sell it, we record an unrealized gain or
loss. The amount of realized gain per share, if any, that we pay to shareholders
would be listed under "Less dividends and distributions from: Net realized gain
on investments."

Net asset value (NAV)
This is the value of a mutual fund share, calculated by dividing the net assets
by the number of shares outstanding.

Total return
This represents the rate that an investor would have earned or lost on an
investment in a fund. In calculating this figure for the financial highlights
table, we include applicable fee waivers, exclude front-end and contingent
deferred sales charges, and assume the shareholder has reinvested all dividends
and realized gains.

Net assets
Net assets represent the total value of all the assets in a fund's portfolio,
less any liabilities, that are attributable to that clasFs of the fund.

Ratio of expenses to average net assets
The expense ratio is the percentage of net assets that a fund pays annually for
operating expenses and management fees. These expenses include accounting and
administration expenses, services for shareholders, and similar expenses.

Ratio of net investment income (loss) to average net assets
We determine this ratio by dividing net investment income (loss) by average net
assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. A
turnover rate of 100% would occur if, for example, a fund bought and sold all of
the securities in its portfolio once in the course of a year or frequently
traded a single security. A high rate of portfolio turnover in any year may
increase brokerage commissions paid and could generate taxes for shareholders on
realized investment gains.

Glossary

How to use this glossary
This glossary includes definitions of investment terms, many of which are used
throughout the Prospectus. If you would like to know the meaning of an
investment term that is not explained in the text please check the glossary.

Amortized cost
Amortized cost is a method used to value a fixed-income security that starts
with the face value of the security and then adds or subtracts from that value
depending on whether the purchase price was greater or less than the value of
the security at maturity. The amount greater or less than the par value is
divided equally over the time remaining until maturity.

Appreciation
An increase in the value of an investment.

Average maturity
An average of when the individual bonds and other debt securities held in a
portfolio will mature.

Bond
A debt security, like an IOU, issued by a company, municipality or government
agency. In return for lending money to the issuer, a bond buyer generally
receives fixed periodic interest payments and repayment of the loan amount on a
specified maturity date. A bond's price changes prior to maturity and typically
is inversely related to current interest rates. Generally, when interest rates
rise, bond prices fall, and when interest rates fall, bond prices rise. See
Fixed-income securities.

Bond ratings
Independent evaluations of creditworthiness, ranging from Aaa/AAA (highest
quality) to D (lowest quality). Bonds rated Baa/BBB or better are considered
investment grade. Bonds rated Ba/BB or lower are commonly known as junk bonds.

agent) who analyzes clients' finances and prepares personalized programs to meet
objectives.

Fixed-income securities

Actual after-tax returns depend on the investor's individual tax situation and
may differ from the returns shown. After-tax returns are not relevant for shares
held in tax-deferred investment vehicles such as employer-sponsored 401(k) plans
and individual retirement accounts. The after-tax returns shown are calculated
using the highest individual federal marginal income tax rates in effect during
the Fund's lifetime and do not reflect the impact of state and local taxes. The
after-tax rate used is based on the current tax characterization of the elements
of the Fund's returns (e.g., qualified vs. non-qualified dividends) and may be
different than the final tax characterization of such elements. Past
performance, both before and after taxes, is not a guarantee of future results.

the current fiscal year because the Fund is not expected to convene a
shareholders' meeting and issue a proxy statement during the current fiscal
year.
(3) The investment manager has contracted to waive fees and pay expenses

(excluding any taxes, interest, brokerage fees, extraordinary expenses and
certain insurance costs) from exceeding 0.65% of average daily net assets.

risk management techniques that can help shareholders meet their goals.

[GRAPHIC OMITTED: EXCHANGE SYMBOL]

By exchange
You may exchange all or part of your investment in one or more Delaware
Investments(R)Funds for shares of other Delaware Investments(R) Funds. Please
keep in mind, however, that you may not exchange your shares for Class B, Class
C or Class R shares. To open an account by exchange, call your Client Services
Representative at 800 510-4015.

[GRAPHIC OMITTED: SYMBOL OF A PERSON]

Through your financial advisor
Your financial advisor can handle all the details of purchasing shares,
including opening an account. Your financial advisor may charge a separate fee
for this service.

We determine the NAV per share for each class of the Fund at the close of
regular trading on the NYSE on each Business Day. The NAV per share for each
class of the Fund is calculated by subtracting the liabilities of each class
from its total assets and dividing the resulting number by the number of shares
outstanding for that class. We generally price securities and other assets for
which market quotations are readily available at their market value. We price
fixed-income securities on the basis of valuations provided to us by an
independent pricing service that uses methods approved by the Board of Trustees.
We price any fixed-income securities that have a maturity of less than 60 days
at amortized cost, which approximates market value. For all other securities, we
use methods approved by the Board of Trustees that are designed to price
securities at their fair market value.

Document delivery
If you have an account in the same Delaware Investments(R)Fund as another person
or entity at your address, we are sending you one copy of the Fund's prospectus,
annual and semiannual reports to that address unless you opt otherwise. This
will help us reduce the printing and mailing expenses associated with the Fund.
We will continue to send one copy of each of these documents to that address
until you notify us that you wish individual materials. If you wish to receive
individual materials, please call your Client Services Representative at 800
510-4015. We will begin sending you individual copies of these documents 30 days
after receiving your request.

How to redeem shares

[GRAPHIC OMITTED: SYMBOL OF AN ENVELOPE]

By mail
You may redeem your shares (sell them back to the Fund) by mail by writing to:
Delaware Investments, 2005 Market Street, Philadelphia, PA 19103-7094. All
owners of the account must sign the request, and for redemptions of more than
$100,000, you must include a signature guarantee for each owner. You can also
fax your written request to 267 256-8990. Signature guarantees are also required
when redemption proceeds are going to an address other than the address of
record on the account.

[GRAPHIC OMITTED: SYMBOL OF A TELEPHONE]

[GRAPHIC OMITTED: SYMBOL OF A JAGGED LINE]

[GRAPHIC OMITTED: SYMBOL OF A PERSON]

Through your financial advisor
Your financial advisor can handle all the details of redeeming your shares. Your
financial advisor may charge a separate fee for this service.

If you hold your shares in certificates, you must submit the certificates with
your request to sell the shares. We recommend that you send your certificates by
certified mail.

When you send us a properly completed request to redeem or exchange shares, and
we or an authorized agent receive the request before the close of regular
trading on the NYSE (normally 4:00 p.m. Eastern Time), you will receive the NAV
as next determined after we receive your request. If we receive your request
after the close of regular trading on the NYSE, you will receive the NAV next
determined on the next Business Day. You may have to pay taxes on the proceeds
from your sale of shares. We will send you a check, normally the next Business
Day, but no later than seven days after we receive your request to sell your
shares. If you purchased your shares by check, we will wait until your check has
cleared, which can take up to 15 days, before we send your redemption proceeds.

Through checkwriting
You may redeem Class A shares by writing checks of $500 or more. Checks must be
signed by all owners of the account unless you indicate otherwise on your
Investment Application. The checkwriting feature is not available for retirement
plans. Also, because dividends are declared daily, you may not close your
account by writing a check. When you write checks you are subject to bank
regulations and may be subject to a charge if the check amount exceeds the value
of your account.

Account minimum
If you redeem shares and your account balance falls below $250, the Fund may
redeem your account after 60 days' written notice to you.

Exchanges You may generally exchange all or part of your shares for shares, of
the same class in another Delaware Investments(R)Fund. If you exchange shares to
a fund that has a sales charge, you will pay any applicable sales charges on
your new shares. You do not pay sales charges on shares that you acquired
through the reinvestment of dividends. You may have to pay taxes on your
exchange. When you exchange sharFes, you are purchasing shares in another fund,
so you should be sure to get a copy of the fund's prospectus and read it
carefully before buying shares through an exchange. You may not exchange your
shares for Class B, Class C or Class R shares of another Delaware
Investments(R)Fund. We may refuse the purchase side of any exchange request, if,
in the investment Manager's judgment, the Fund would be unable to invest
effectively in accordance with its investment objectives and policies or would
otherwise potentially be adversely affected.

Market timing of a fund occurs when investors make consecutive, rapid,
short-term "roundtrips" - that is, purchases into a fund followed quickly by
redemptions out of that fund. A short-term roundtrip is any redemption of fund
shares within 20 business days of a purchase of that fund's shares. If you make
a second such short-term roundtrip in a fund within the same calendar quarter as
a previous short-term roundtrip in that fund, you may be considered a market
timer. In determining whether market timing has occurred, the Fund will consider
short-term roundtrips to include rapid purchases and sales of Fund shares
through the exchange privilege. The Fund reserves the right to consider other
trading patterns to be market timing.

The Fund reserves the right to modify this policy at any time without notice,
including modifications to the Fund's monitoring procedures and the procedures
to close accounts to new purchases. Although the implementation of this policy
involves judgments that are inherently subjective, we seek to apply this policy
uniformly in all cases and to make judgments and applications that are
consistent with the interests of the Fund's shareholders. While we will take
actions designed to detect and prevent market timing, there can be no assurance
that such trading activity will be completely eliminated. Moreover, the Fund's
market timing policy does not require the Fund to take action in response to
frequent trading activity.

Risks of market timing
By realizing profits through short-term trading, shareholders that engage in
rapid purchases and sales or exchanges of the Fund's shares dilute the value of
shares held by long-term shareholders. Volatility resulting from excessive
purchases and sales or exchanges of Fund shares, especially involving large
dollar amounts, may disrupt efficient portfolio management. In particular, the
Fund may have difficulty implementing its long-term investment strategies if it
is forced to maintain a higher level of its assets in cash to accommodate
significant short-term trading activity. Excessive purchases and sales or
exchanges of the Fund's shares may also force the Fund to sell portfolio
securities at inopportune times to raise cash to accommodate short-term trading
activity. This could adversely affect the Fund's performance if, for example,
the Fund incurs increased brokerage costs and realization of taxable capital
gains without attaining any investment advantage.

may seek to engage in short-term trading to take advantage of these pricing
differences. Funds that may be adversely affected by such arbitrage include, in
particular, funds that significantly invest in small-cap securities, technology
and other specific industry sector securities, and in certain fixed-income
securities, such as high-yield bonds, asset-backed securities or municipal
bonds.

Limitations on ability to detect and curtail market timing Shareholders seeking
to engage in market timing may employ a variety of strategies to avoid detection
and, despite the efforts of the Fund and its agents to detect market timing in
Fund shares, there is no guarantee that the Fund will be able to identify these
shareholders or curtail their trading practices. In particular, the Fund may not
be able to detect market timing attributable to a particular investor who
effects purchase, redemption and/or exchange activity in Fund shares through
omnibus accounts. The difficulty of detecting market timing may be further
compounded if these entities utilize multiple tiers or omnibus accounts.

long you have owned your shares. A portion of income dividends designated by the
Fund may be qualified dividend income eligible for taxation by individual
shareholders at long-term capital gain rates provided certain holding period
requirements are met.

Certain management considerations

Manager of managers structure
At a shareholder meeting held on March 23, 2005 (or as adjourned), the Fund's
shareholders approved a "manager of managers" structure that would permit the
Manager to appoint and replace sub-advisors, enter into sub-advisory agreements,
and amend and terminate sub-advisory agreements with respect to the Fund,
subject to Board approval but without shareholder approval (the "Manager of
Managers Structure"). While the Manager does not currently expect to use the
Manager of Managers Structure with respect to the Fund, the Manager may, in the
future, recommend to the Fund's Board the establishment of the Manager of
Managers Structure by recommending the hiring of one or more sub-advisors to
manage all or a portion of the Fund's portfolio if it believes that doing so
would be likely to enhance the Fund's performance by introducing a different
investment style or focus.

fund's investments; it is after expenses have been deducted.

Net asset value (NAV)
This is the value of a mutual fund share, calculated by dividing the net assets

Total return
This represents the rate that an investor would have earned or lost on an

Net assets
Net assets represent the total value of all the assets in a fund's portfolio,
less any liabilities, that are attributable to that class of the fund.

Ratio of net investment income (loss) to average net assets
We determine this ratio by dividing net investment income (loss) by average net
