Profile: Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund
------------------------------------------------------------------------------

What are the Funds' goals?

Both Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund seek
to provide investors with total return. Although each Fund will strive to meet
its goal, there is no assurance that it will.

What are the Funds' main investment strategies?
We invest primarily in corporate bonds. Our focus is on corporate bonds that
have investment grade credit ratings from a nationally recognized statistical
ratings organization (NRSRO). The bonds we select for the portfolio are
typically rated BBB and above by Standard and Poor's or Baa and above by Moody's
Investors Service, Inc. We may also invest in unrated bonds, if we believe their
credit quality is comparable to those that have investment grade ratings.

The most significant difference between the two Funds is in their return
potential and their risk profiles as determined by the average duration of the
bonds in each Fund's portfolio. Duration measures a bond's sensitivity to
interest rates by indicating the approximate change in a bond or bond fund's
price given a 1% change in interest rates. We generally keep Delaware Corporate
Bond Fund's duration between four and seven years. This is a more conservative
strategy than that of Delaware Extended Duration Bond Fund, which will typically
have a duration between eight and eleven years.

What are the main risks of investing in the Funds?
Investing in any mutual fund involves risk, including the risk that you may lose
part or all of the money you invest. The value of your investment will increase
and decrease according to changes in the value of the securities in the Funds'
portfolio. These Funds will be affected by changes in bond prices, particularly
as a result of changes in interest rates. They may also be affected by economic
conditions which may hinder a company's ability to make interest and principal
payments on its debt.

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

An investment in the Funds 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 Funds
     o Investors with medium or long-range goals.
     o Investors looking for a bond investment to help balance their investments
       in stocks or more aggressive securities.
     o Investors who are looking for an income investment that can provide total
       return opportunities through the automatic reinvestment of income
       dividends.

Who should not invest in the Funds
     o Investors with very short-term financial goals.
     o Investors who are unwilling to accept share prices that may fluctuate,
       sometimes significantly, over the short term.
     o Investors seeking long-term growth of capital.

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

                                                                               3

How have the Funds performed?

This bar chart and table can help you evaluate the risks of investing in the
Funds. We show returns for the Funds' Class A shares for the past calendar year,
as well as average annual returns of all shares for one-year and lifetime
periods. A Fund's past performance does not necessarily indicate how it will
perform in the future. The returns reflect expense limitations. The returns
would be lower without the limitations.

[bar chart]

Total return (Class A)

----------------------------------------------------------------
                                                           1999
----------------------------------------------------------------
Delaware Corporate Bond Fund                             -2.02%
----------------------------------------------------------------
Delaware Extended Duration Bond Fund                     -5.57%
----------------------------------------------------------------

As of June 30, 2000, the Delaware Corporate Bond Fund's Class A shares had a
calendar year-to-date return of 0.53%. During the period illustrated in this bar
chart, Class A's highest quarterly return was 0.97% for the quarter ended
December 31, 1999 and its lowest quarterly return was -1.97% for the quarter
ended June 30, 1999.

As of June 30, 2000, the Delaware Extended Duration Bond Fund's Class A shares
had a calendar year-to-date return of 0.39%. During the period illustrated in
this bar chart, Class A's highest quarterly return was -0.22% for the quarter
ended September 30, 1999 and its lowest quarterly return was -3.07% for the
quarter ended June 30, 1999.

The maximum Class A sales charge of 4.75%, which is normally deducted when you
purchase shares, is not reflected in the total returns in the previous
paragraphs or in the bar chart. If this fee were included, the returns would be
less than those shown. The average annual returns shown in the table on page __
do include the sales charge.

remember that unlike the Funds, the indexes are unmanaged and don't reflect the
costs of operating a mutual fund, such as the costs of buying, selling and
holding securities.

* If shares were not redeemed, the returns for Delaware Corporate Bond Fund's
  Class B would be -2.76% and 0.07% for the one-year and lifetime periods,
  respectively. Returns for Class C would be -2.75% and 0.07% for the one-year
  and lifetime periods, respectively. The returns for the Delaware Extended
  Duration Bond Fund's Class B would be -6.28% and -2.77% for the one-year and
  lifetime periods, respectively. Returns for Class C would be -6.28% and -2.66%
  for the one-year and lifetime periods, respectively.

This example is intended to help you compare the cost of investing in the Funds
to the cost of investing in other mutual funds with similar investment
objectives. We show the cumulative amount of Fund expenses on a hypothetical
investment of $10,000 with an annual 5% return over the time shown.(6) This is
an example only, and does not represent future expenses, which may be greater or
less than those shown here.

(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 adviser who is
    paid a commission, a contingent deferred sales charge will apply to
    redemptions made within the first 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 two years after you buy them,
    you will pay a contingent deferred sales charge of 4%, which declines to 3%
    during the third and fourth years, 2% during the fifth year, 1% during the
    sixth year, and 0% thereafter.

(3) Class C shares redeemed within one year of purchase are subject to a 1%
    contingent deferred sales charge.

(4) Payments under the Class A 12b-1 plan may not exceed 0.30% of average daily
    net assets. However, the Board of Trustees set the 12b-1 plan expenses for
    the Fund's Class A shares at 0.25%.

(5) The investment manager has contracted to waive fees and pay expenses from
    October 1, 1999 through September 30, 2001 in order to prevent total
    operating expenses (excluding any 12b-1 plan expenses, taxes, interest,
    brokerage fees and extraordinary expenses) from exceeding 0.55% of average
    daily net assets.

(6) The Fund's actual rate of return may be greater or less than the
    hypothetical 5% return we use here. This example reflects the net operating
    expenses with the expense waivers for year one and the total operating
    expenses without expense waivers for years two through ten.

(7) The Class B example reflects the conversion of Class B shares to Class A
    shares after approximately eight years. Information for the ninth and tenth
    years reflects expenses of the Class A shares.

How we manage the Funds

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

Investment strategy

We analyze economic and market conditions, seeking to identify the securities or
market sectors that we think are the best investments for the Funds. Following
are descriptions of how the portfolio manager pursues the Funds' investment
goals.

The Funds strive to provide shareholders with total return through a combination
of income and capital appreciation from the bonds in their portfolios. We invest
primarily in corporate bonds, with a strong emphasis on those that are rated in
the four highest credit categories by an NRSRO. We may also invest in
high-yielding, lower quality corporate bonds (also called "junk bonds"). These
may involve greater risk because the companies issuing the bonds have lower
credit ratings and may have difficulty making interest and principal payments.

In selecting bonds we conduct a careful analysis of economic factors,
industry-related information and the underlying financial stability of the
company issuing the bond.

Choosing Between Delaware Corporate Bond Fund and Delaware Extended Duration
Bond Fund We manage both Delaware Corporate Bond Fund and Delaware Extended
Duration Bond Fund using the same fundamental strategy. The main difference
between the two Funds is in their return potential and the corresponding risk
associated with each Fund. Delaware Corporate Bond Fund is the more conservative
of the two Funds and might be appropriate for investors who desire less
potential for fluctuation of their share price. We generally keep Delaware
Corporate Bond Fund's duration between four and seven years. Delaware Extended
Duration Bond Fund will typically have a duration between eight and 11 years.
This longer duration gives Delaware Extended Duration Bond Fund greater income
potential as well as greater appreciation potential when interest rates decline.

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

                                                                               7

The securities we typically invest in
Fixed-income securities generally offer the potential for greater income
payments than stocks, and also may provide capital appreciation.

Lending securities

Each Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for its use in security transactions. These
transactions, if any, may generate additional income for the Funds.

Borrowing from banks
Each Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions. Borrowing money could result in a Fund being unable
to meet its investment objective. A Fund will not borrow money in excess of
one-third of the value of its net assets.

Purchasing securities on a when-issued or delayed delivery basis
Each 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. Each Fund will designate cash or securities in amounts sufficient to cover
its obligations and will value the designated assets daily.

Temporary defense positions
We may hold a substantial part of each Fund's assets in cash or cash equivalents
as a temporary, defensive strategy. To the extent that a Fund holds these
securities, the Fund may be unable to achieve its investment objective.

Portfolio turnover
We anticipate that each Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if a Fund sold and replaced securities
valued at 100% of its net assets within one year. High turnover can result in
increased transaction costs and tax liability for investors.

                                                                              10

The risks of investing in the Funds

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 a Fund you should
carefully evaluate the risks. Because of the nature of the Funds, you should
consider your investment to be a long-term investment that typically provides
the best results when held for a number of years. Following are the chief risks
you assume when you invest in the Funds. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

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. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.

                                                                              13

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 advisers Financial advisers provide advice to their clients--analyzing
their financial objectives and recommending appropriate funds or other
investments. Financial advisers are compensated for their services, generally
through sales commissions, and through 12b-1 and/or service fees deducted from
the fund's assets.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

                                                                              14

About your account

Investing in the Funds
You can choose from a number of share classes for each Fund. Because each share
class has a different combination of sales charges, fees, and other features,
you should consult your financial adviser 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 4.75% that you pay when
  you buy the shares. The offering price for Class A shares includes the
  front-end sales charge.

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

o You may qualify for other reduced sales charges, as described in "How to
  reduce your sales charge," and under certain circumstances the sales charge
  may be waived; please see the Statement of Additional Information.

o Class A shares are also subject to an annual 12b-1 fee no greater than 0.30%
  (currently 0.25%) of average daily net assets, which is lower than the 12b-1
  fee for Class B and Class C shares.

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

financial adviser is paid a commission on your purchase, you will have to pay a limited contingent deferred sales charge of 1%
if you redeem these shares within the first year after your purchase and 0.50% if you redeem them within the second year, unless
a specific waiver of the charge applies.

Class B

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

o If you redeem Class B shares during the first two years after you buy them,
  the shares will be subject to a contingent deferred sales charge of 4%. The
  contingent deferred sales charge is 3% during the third and fourth years, 2%
  during the fifth year, 1% during the sixth year, and 0% thereafter.

o Under certain circumstances the contingent deferred sales charge may be
  waived; please see the Statement of Additional Information.

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

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

o Approximately eight 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% (currently
  0.25%). Conversion may occur as late as three months after the eighth
  anniversary of purchase, during which time Class B's higher 12b-1 fees apply.

o You may purchase up to $250,000 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 a Fund. However, you will pay a contingent deferred
  sales charge of 1% if you redeem your shares within 12 months after you buy
  them.

o Under certain circumstances the contingent deferred sales charge may be
  waived; please see the Statement of Additional Information.

o Class C shares are subject to an annual 12b-1 fee which may not be greater
  than 1% 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 pay
  lower dividends than Class A 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.

Each share class of the Funds has adopted a separate 12b-1 plan that allows it
to pay distribution fees for the sales and distribution of its shares. Because
these fees are paid out of the Funds' 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.

                                                                              16

About your account (continued)

How to buy shares (continued)


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. 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 is $250, and you can make additional
investments of only $25. The minimum for an Education IRA is $500. The minimums
vary for retirement plans other than IRAs, Roth IRAs or Education IRAs.

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

We determine each Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in each Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market.


Retirement plans
In addition to being an appropriate investment for your Individual Retirement
Account (IRA), Roth IRA and Education IRA, shares in the Funds 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 these Funds can play an important role in your
retirement planning or for details about group plans, please consult your
financial adviser, or call 800.523.1918.


                                                                              19

How to redeem shares

[GRAPHIC OMITTED: ILLUSTRATION OF A PERSON]

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

[GRAPHIC OMITTED: ILLUSTRATION OF AN ENVELOPE]

By mail
You can redeem your shares (sell them back to the fund) by mail by writing to:
Delaware Investments, 1818 Market Street, Philadelphia, PA 19103-3682. All
owners of the account must sign the request, and for redemptions of more than
$50,000, 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 an account.

[GRAPHIC OMITTED: ILLUSTRATION OF A TELEPHONE]

By telephone
You can redeem up to $50,000 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: ILLUSTRATION OF A JAGGED LINE]


By wire
You can redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account 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: ILLUSTRATION OF A KEYPAD]

Through automated shareholder services
You can 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.



                                                                              20

About your account (continued)

How to redeem shares (continued)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 p.m. Eastern time), you will receive the net asset value as determined on
the business day we receive your request. 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' net
asset value when you purchased them or their net asset value 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 required account
minimum of $1,000 ($250 for IRAs, Uniform Gift to Minors Act and Uniform
Transfers to Minors Act accounts or accounts with automatic investing plans,
$500 for Education IRAs) 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,
a Fund may redeem your account after 60 days' written notice to you.



                                                                              21

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.

Wealth Builder Option
With the Wealth Builder Option you can arrange automatic monthly exchanges
between your shares in one or more Delaware Investments 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 fund in the
Delaware Investments family. 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 can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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 you
will pay any applicable sales charges 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 don't 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.



                                                                              22

Special services (continued)

MoneyLine(SM) On Demand Service
Through our MoneyLineSM On Demand Service, you or your financial adviser may
transfer money between your Fund account and your predesignated bank account by
telephone request. This service is not available for retirement plans, except
for purchases into IRAs. MoneyLine has a minimum transfer of $25 and a maximum
transfer of $50,000.

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.

Dividends, distributions and taxes
Dividends, if any, are declared daily and paid monthly. Capital gains, if any,
are paid twice a year. We automatically reinvest all dividends and any capital
gains, unless you tell us otherwise.


Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from a Fund is the same whether you reinvest
your dividends or receive them in cash. Distributions from a Fund's long-term
capital gains are taxable as capital gains, while distributions from short-term
capital gains and net investment income are generally taxable as ordinary
income. Any capital gains may be taxable at different rates depending on the
length of time a Fund held the assets. In addition, you may be subject to state
and local taxes on distributions.

We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.



                                                                              23

Certain management considerations


Investments by fund of funds
Each Fund accepts investments from the series portfolios of Delaware Group
Foundation Funds, a fund of funds. From time to time, a Fund may experience
large investments or redemptions due to allocations or rebalancings by
Foundation Funds. While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management.
For example, a 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 Foundation Funds and will attempt to minimize any adverse effects on the
Funds and Foundation Funds as a result of these transactions.




                                                                              24

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 (loss) on investments occurs when we sell an investment at a
profit, while a realized loss on investments 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
that we pay to shareholders, if any, would be listed under "Less dividends and
distributions-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 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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.


                                                                              27

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.


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.
See also Nationally recognized statistical ratings organization.


Capital
The amount of money you invest.

Capital appreciation
An increase in the value of an investment.

Capital gains distributions
Payments to mutual fund shareholders of profits (realized gains) from the sale
of a fund's portfolio securities. Usually paid once a year; may be either

compensate a financial adviser for advice and service, rather than an up-front
commission.

Corporate bond

Profile: Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund

What are the Funds' goals?
Both Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund seek
to provide investors with total return. Although each Fund will strive to meet
its goal, there is no assurance that it will.

What are the Funds' main investment strategies?
We invest primarily in corporate bonds. Our focus is on corporate bonds that
have investment grade credit ratings from a nationally recognized statistical
ratings organization (NRSRO). The bonds we select for the portfolio are
typically rated BBB and above by Standard and Poor's or Baa and above by Moody's
Investors Service, Inc. We may also invest in unrated bonds, if we believe their
credit quality is comparable to those that have investment grade ratings.

The most significant difference between the two Funds is in their return
potential and their risk profiles as determined by the average duration of the
bonds in each Fund's portfolio. Duration measures a bond's sensitivity to
interest rates by indicating the approximate change in a bond or bond fund's
price given a 1% change in interest rates. We generally keep Delaware Corporate
Bond Fund's duration between four and seven years. This is a more conservative
strategy than that of Delaware Extended Duration Bond Fund, which will typically
have a duration between eight and 11 years.

What are the main risks of investing in the Funds?
Investing in any mutual fund involves risk, including the risk that you may lose
part or all of the money you invest. The value of your investment will increase
and decrease according to changes in the value of the securities in the Funds'
portfolio. These Funds will be affected by changes in bond prices, particularly
as a result of changes in interest rates. They may also be affected by economic
conditions which may hinder a company's ability to make interest and principal
payments on its debt.

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

An investment in the Funds 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 Funds
  o Investors with medium or long-range goals.
  o Investors looking for a bond investment to help balance their investments in
    stocks or more aggressive securities.
  o Investors who are looking for an income investment that can provide total
    return opportunities through the automatic reinvestment of income dividends.

Who should not invest in the Funds
  o Investors with very short-term financial goals.
  o Investors who are unwilling to accept share prices that may fluctuate,
    sometimes significantly, over the short term.
  o Investors seeking long-term growth of capital.

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

                                                                               3

How have the Funds performed?
This bar chart and table can help you evaluate the risks of investing in the
Funds. We show returns for the past calendar year, as well as average annual
returns for one-year and lifetime periods. A Fund's past performance does not
necessarily indicate how it will perform in the future. The returns reflect
expense limitations. The returns would be lower without the limitations.

How we manage the Funds

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

Investment strategy
We analyze economic and market conditions, seeking to identify the securities or
market sectors that we think are the best investments for the Funds. Following
are descriptions of how the portfolio manager pursues the Funds' investment
goals.

The Funds strive to provide shareholders with total return through a combination
of income and capital appreciation from the bonds in their portfolios. We invest
primarily in corporate bonds, with a strong emphasis on those that are rated in
the four highest credit categories by an NRSRO. We may also invest in
high-yielding, lower quality corporate bonds (also called "junk bonds"). These
may involve greater risk because the companies issuing the bonds have lower
credit ratings and may have difficulty making interest and principal payments.

In selecting bonds we conduct a careful analysis of economic factors,
industry-related information and the underlying financial stability of the
company issuing the bond.

Choosing Between Delaware Corporate Bond Fund and Delaware Extended Duration
Bond Fund We manage both Delaware Corporate Bond Fund and Delaware Extended
Duration Bond Fund using the same fundamental strategy. The main difference
between the two Funds is in their return potential and the corresponding risk
associated with each Fund. Delaware Corporate Bond Fund is the more conservative
of the two Funds and might be appropriate for investors who desire less
potential for fluctuation of their share price. We generally keep Delaware
Corporate Bond Fund's duration between four and seven years. Delaware Extended
Duration Bond Fund will typically have a duration between eight and 11 years.
This longer duration gives Delaware Extended Duration Bond Fund greater income
potential as well as greater appreciation potential when interest rates decline.

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


                                                                               6

The securities we typically invest in
Fixed-income securities generally offer the potential for greater income
payments than stocks, and also may provide capital appreciation.

Lending securities
Each Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for its use in security transactions. These
transactions, if any, will generate additional income for the Funds.

Borrowing from banks
Each Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions. Borrowing money could result in a Fund being unable
to meet its investment objective. A Fund will not borrow money in excess of
one-third of the value of its net assets.

Purchasing securities on a when-issued or delayed delivery basis
Each 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. Each Fund will designate cash or securities in amounts sufficient to cover
its obligations and will value the designated assets daily.

Temporary defense positions
We may hold a substantial part of each Fund's assets in cash or cash equivalents
as a temporary, defensive strategy. To the extent that a Fund holds these
securities, the Fund may be unable to achieve its investment objective.

Portfolio turnover
We anticipate that each Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if a Fund sold and replaced securities
valued at 100% of its net assets within one year. High turnover can result in
increased transaction costs and tax liability for investors.

                                                                               9

The risks of investing in the Funds
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 a Fund you should
carefully evaluate the risks. Because of the nature of the Funds, you should
consider your investment to be a long-term investment that typically provides
the best results when held for a number of years. Following are the chief risks
you assume when you invest in the Funds. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

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. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.

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.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

About your account (continued)

How to buy shares (continued)


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

We determine each Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in each Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market value.



                                                                              16

How to redeem shares

[GRAPHIC OMITTED: ILLUSTRATION OF AN ENVELOPE]


By mail
You can redeem your shares (sell them back to the fund) by mail by writing to:
Delaware Investments, 1818 Market Street, Philadelphia, PA 19103-3682. All
owners of the account must sign the request, and for redemptions of more than
$50,000, you must include a signature guarantee for each owner. You can also fax
your written request to 215.255.8864. Signature guarantees are also required
when redemption proceeds are going to an address other than the address of
record on an account.


[GRAPHIC OMITTED: ILLUSTRATION OF A TELEPHONE]

By telephone
You can redeem up to $50,000 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: ILLUSTRATION OF A JAGGED LINE]

By wire
You can redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account the next business day after we receive your
request. Bank information must be on file before you request a wire redemption.

Your financial adviser can handle all the details of redeeming your shares. Your

About your account (continued)

How to redeem shares (cont.)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 pm Eastern time), you will receive the net asset value as determined on the
business day we receive your request. 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.

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

Exchanges
You can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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
don't pay sales charges on shares that are 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. You may not exchange your shares for Class B and Class C shares of the
funds in the Delaware Investments family.

Dividends, distributions and taxes
Dividends, if any, are declared daily and paid monthly. Capital gains, if any,
are paid twice a year. We automatically reinvest all dividends and any capital
gains.

Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from a Fund is the same whether you reinvest
your dividends or receive them in cash. Distributions from a Fund's long-term
capital gains are taxable as capital gains, while distributions from short-term
capital gains and net investment income are generally taxable as ordinary
income. Any capital gains may be taxable at different rates depending on the
length of time a Fund held the assets. In addition, you may be subject to state
and local taxes on distributions.

We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.






                                                                              18

Certain management considerations


Investments by Fund of Funds
Each Fund accepts investments from the series portfolios of Delaware Group
Foundation Funds, a fund of funds. From time to time, a Fund may experience
large investments or redemptions due to allocations or rebalancings by
Foundation Funds. While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management.
For example, a 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 Foundation Funds and will attempt to minimize any adverse effects on the
Funds and Foundation Funds as a result of these transactions.






                                                                              19

How to read the Financial highlights

Net investment income
Net investment income 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 (loss) on investments occurs when we sell an investment at a
profit, while a realized loss on investments 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
that we pay to shareholders, if any, would be listed under "Less dividends and
distributions-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 fee waivers, 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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.


                                                                              23

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.


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.
See also Nationally recognized statistical ratings organization.


Capital
The amount of money you invest.

Capital appreciation
An increase in the value of an investment.

Capital gains distributions
Payments to mutual fund shareholders of profits (realized gains) from the sale
of a fund's portfolio securities. Usually paid once a year; may be either
short-term gains or long-term gains.

Compounding
Earnings on an investment's previous earnings.

Consumer Price Index (CPI)
Measurement of U.S. inflation; represents the price of a basket of commonly
purchased goods.

Corporate bond
A debt security issued by a corporation. See Bond.

Depreciation
A decline in an investment's value.

Diversification
The process of spreading investments among a number of different securities,
asset classes or investment styles to reduce the risks of investing.

Dividend distribution
Payments to mutual fund shareholders of dividends passed along from the fund's
portfolio of securities.

Duration
A measurement of a fixed-income investment's price volatility. The larger the
number, the greater the likely price change for a given change in interest
rates.

                                                                              24

Expense ratio
A mutual fund's total operating expenses, expressed as a percentage of its total
net assets. Operating expenses are the costs of running a mutual fund, including
management fees, offices, staff, equipment and expenses related to maintaining
the fund's portfolio of securities and distributing its shares. They are paid
from the fund's assets before any earnings are distributed to shareholders.

Financial adviser
Financial professional (e.g., broker, banker, accountant, planner or insurance
agent) who analyzes clients' finances and prepares personalized programs to meet
objectives.

Fixed-income securities
With fixed-income securities, the money you originally invested is paid back at
a pre-specified maturity date. These securities, which include government,
corporate or municipal bonds, as well as money market securities, typically pay
a fixed rate of return (often referred to as interest). See Bond.

Government securities
Securities issued by U.S. government or its agencies.  They include Treasuries
as well as agency-backed securities such as Fannie Maes.

Inflation
The increase in the cost of goods and services over time. U.S. inflation is

Investment goal
The objective, such as long-term capital growth or high current income, that a
mutual fund pursues.

investment grade domestic corporate bonds and Yankee issues.


Management fee
The amount paid by a mutual fund to the investment adviser for management
services, expressed as an annual percentage of the fund's average daily net
assets.

Market capitalization
The value of a corporation determined by multiplying the current market price of
a share of common stock by the number of shares held by shareholders. A
corporation with one million shares outstanding and the market price per share
of $10 has a market capitalization of $10 million.

Maturity
The length of time until a bond issuer must repay the underlying loan principal
to bondholders.


NASD Regulation, Inc. (NASDR(SM))

and are sometimes convertible into common stock.


Price/earnings ratio

Profile:  Delaware Delchester Fund

What is the Fund's goal?
Delaware Delchester Fund seeks as high a level of current income as is
consistent with providing reasonable safety. Although the Fund will strive to
meet its goal, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in high-yielding corporate bonds rated BB or lower by
Standard and Poor's or similarly rated by another nationally recognized
statistical ratings organization (NRSRO). These are commonly known as high-yield
bonds or junk bonds and involve greater risks than investment grade bonds. We
may also invest in unrated bonds if we judge them to be of comparable quality.
We will select bonds primarily based on the income potential they offer and on
our evaluation of the bond issuers' ability to make interest payments and repay
principal.

We may also invest in equity securities, foreign government securities and
corporate bonds of foreign issuers. Though not expected to be a significant
component of our strategy under normal circumstances, we may also invest in
investment grade corporate bonds, U.S. government securities and high quality
commercial paper.

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. 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 declines in
bond prices, which can be caused by an adverse change in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. High-yield bonds are rated below investment grade and are subject to
greater risk that the issuer will be unable to make payments on interest and
principal, particularly under adverse economic conditions. Bonds of foreign
issuers are also subject to certain risks such as political and economic
instability, currency fluctuations and less stringent regulatory standards.

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

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.

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 adviser to
determine whether it is an appropriate choice for you.

Who should invest in the Fund

    o Investors looking for a fixed-income investment that offers potential for
      very high current income.

    o Investors with long-term financial goals.

Who should not invest in the Fund
    o Investors with short-term financial goals.
    o Investors who are unwilling to own an investment whose value may
      fluctuate, sometimes significantly, over the short term.


                                                                               3

(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 adviser 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 two years after you buy them,
    you will pay a contingent deferred sales charge of 4%, which declines to 3%
    during the third and fourth years, 2% during the fifth year, 1% during the
    sixth year, and 0% thereafter.
(3) Class C shares redeemed within one year of purchase are subject to a 1%
    contingent deferred sales charge.
(4) The Board of Trustees adopted a formula for calculating 12b-1 plan expenses
    for Delaware Delchester Fund's Class A shares that went into effect on June
    1, 1992. Under this formula, 12b-1 plan expenses will not be more than 0.30%
    nor less than 0.10%.
(5) The investment manager has agreed to waive fees and pay expenses in order to
    prevent total operating expenses (excluding 12b-1 plan expenses, taxes,
    interest, brokerage fees and extraordinary expenses) from exceeding 0.90% of
    average daily net assets from June 1, 2000 through November 30, 2000.
(6) The Fund's actual rate of return may be greater or less than the
    hypothetical 5% return we use here. Also, this example assumes that the
    Fund's total operating expenses remain unchanged in each of the periods we
    show.
(7) The Class B example reflects the conversion of Class B shares to Class A
    shares after approximately eight years. Information for the ninth and tenth
    years reflects expenses of the Class A shares.

Profile: Delaware High-Yield Opportunities Fund

What is the Fund's goal?
Delaware High-Yield Opportunities Fund seeks total return and, as a secondary
objective, high current income. Although the Fund will strive to meet its goal,
there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in corporate bonds rated BB or lower by S&P or similarly
rated by another NRSRO. These are commonly known as high-yield bonds or junk
bonds and involve greater risks than investment grade bonds. The Fund will also
invest in unrated bonds we judge to be of comparable quality. Unrated bonds may
be more speculative in nature than rated bonds. The Fund may also invest in U.S.
and foreign government securities and corporate bonds of foreign issuers. In
selecting bonds for the portfolio, we evaluate the income provided by the bond
and the bond's appreciation potential as well as the issuer's ability to make
income and principal payments.

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. 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 declines in
bond prices, which can be caused by adverse changes in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. High-yield bonds are rated below investment grade and are subject to
greater risk that the issuer will be unable to make payments on interest and
principal, particular under adverse conditions. Bonds of foreign issuers are
also subject to certain risks such as political and economic instability,
currency fluctuations and less stringent regulatory standards.

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

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.

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 adviser to

Who should invest in the Fund
    o Investors with long-term financial goals.
    o Investors looking for a fixed-income investment that offers a
      combination of total return with high current income.
    o Investors who want a total return-oriented income investment as a
      diversification tool for long-term, equity -oriented portfolios.

Who should not invest in the Fund
    o Investors with short-term financial goals.
    o Investors who are unwilling to own an investment whose value may
      fluctuate, sometimes significantly, over the short term.


                                                                               8

How has Delaware High-Yield Opportunities Fund performed?

This bar chart and table can help you evaluate the risks of investing in the
Fund. We show returns for the Fund's Class A shares for the past three calendar
years, as well as the average annual returns of all shares for one year and
since inception. The Fund's past performance does not necessarily indicate how
it will perform in the future. The returns reflect expense limitations. The
returns would be lower without the expense limitations.

is unmanaged and doesn't reflect the actual costs of operating a mutual fund,
such as the costs of buying, selling and holding securities.

*  If shares were not redeemed, the returns for Class B would be 4.02% and 0.58%
   for the one-year and lifetime periods, respectively. Returns for Class C
   would be 4.01% and 0.57% for the one-year and lifetime periods, respectively.
** Lifetime returns are shown if the Fund or Class existed for less than 10
   years. Salomon Smith Barney Cash Pay High-Yield Index returns are for the
   Class A lifetime period. The index return for Class B and Class C lifetime
   was 1.27%. Maximum sales charges are included in the Fund returns above.

(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 adviser 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 two years after you buy them,
    you will pay a contingent deferred sales charge of 4%, which declines to 3%
    during the third and fourth years, 2% during the fifth year, 1% during the
    sixth year, and 0% thereafter.
(3) Class C shares redeemed within one year of purchase are subject to a 1%
    contingent deferred sales charge.
(4) The investment manager has contracted to waive fees and pay expenses from
    October 1, 1999 through September 30, 2001 in order to prevent total
    operating expenses (excluding any 12b-1 plan expenses, taxes, interest,
    brokerage fees and extraordinary expenses) from exceeding 1.00% of average
    daily net assets.
(5) The Fund's actual rate of return may be greater or less than the
    hypothetical 5% return we use here. This example reflects the net operating
    expenses with expense waivers for year one and the total operating expenses
    without expense waivers for years two through ten.
(6) The Class B example reflects the conversion of Class B shares to Class A
    shares after approximately eight years. Information for the ninth and tenth
    years reflects expenses of the Class A shares.

How we manage the Funds

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

Our investment strategies
We analyze economic and market conditions, seeking to identify the securities or
market sectors that we think are the best investments for a particular fund.
Following are descriptions of how the portfolio managers pursue the Funds'
investment goals.

For both Delaware Delchester Fund and Delaware High-Yield Opportunities Fund, we
invest primarily in fixed-income securities that we believe will have a liberal
and consistent yield and will tend to reduce the risk of market fluctuations. We
expect to invest the majority of the Funds' assets primarily in high-yield bonds
or junk bonds, which involve greater risks than investment grade bonds. The
Funds may also invest in unrated bonds that we consider to have comparable
credit characteristics. Unrated bonds may be more speculative in nature than
rated bonds.

Before selecting high-yield corporate bonds, we carefully evaluate each
individual bond including its income potential and the size of the bond
issuance. The size of the issuance helps us evaluate how easily we may be able
to buy and sell the bond.

We also do a thorough credit analysis of the issuer to determine whether that
company has the financial ability to meet the bond's payments.

We maintain a well-diversified portfolio of high-yield bonds that represents
many different sectors and industries. Through diversification we can help to
reduce the impact that any individual bond might have on the portfolio should
the issuer have difficulty making payments.

Delaware Delchester Fund
Our primary goal for Delaware Delchester Fund is to provide high current income.
For this reason, the income potential of a bond is a key selection criteria.

It is our policy to invest at least 80% of our assets in corporate bonds, U.S.
government securities or commercial paper of companies rated A-1 or A-2 by S&P
or P-1 or P-2 by Moody's Investors Service, Inc. (which are two NRSROs). We are
required to invest primarily in corporate bonds rated BBB or below; however we
particularly emphasize those rated BB or B. We generally focus more on bonds
rated B in times of economic growth and more on bonds rated BB when the economy
appears to be slowing. The Fund also may invest in bonds of foreign issuers and
equity securities in pursuit of its objective.

Delaware High-Yield Opportunities Fund
Delaware High-Yield Opportunities Fund strives to provide total return, with
income as a secondary objective. Before purchasing a bond, we evaluate both the
income level and its potential for price appreciation. At least 65% of the
Fund's assets will be invested in corporate bonds rated at the time of purchase
as BB or lower by S&P or similarly rated by another NRSRO or, if unrated, that
we judge to be of comparable quality. The Fund also may invest in bonds of
foreign issuers in pursuit of its objective.


                                                                              12

<PAGE>


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


                                                                              13

The securities we typically invest in
Fixed-income securities generally offer the potential for greater income
payments than stocks, and also may provide capital appreciation.

</TABLE>

Delaware Delchester Fund and Delaware High-Yield Opportunities Fund may also
invest in other income producing and non-income producing securities including
common stocks and preferred stocks, some of which may have convertible features
or attached warrants. Please see the Statement of Additional Information for
additional descriptions on these securities as well as those listed in the table
above.

Lending securities
Each Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for their use in security transactions. These
transactions, if any, may generate additional income for the Funds.

Borrowing from banks
Each Fund is permitted to borrow money but normally does not do so. As a
temporary measure for extraordinary purposes or to meet redemption requests, a
Fund may borrow up to one-third of the value of its assets. Borrowing money
could result in the Funds being unable to meet their investment objectives.

Purchasing securities on a when-issued or delayed delivery basis
Delaware Delchester Fund and Delaware High-Yield Opportunities Fund may buy or
sell securities on a when-issued or delayed delivery basis; that is, paying for
securities before delivery or taking delivery up to 45 days later. Each 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 each Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if a Fund sold and replaced securities
valued at 100% of its net assets within one year. High turnover can result in
increased transaction costs and tax liability for investors.

The risks of investing in the Funds
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 a Fund you should
carefully evaluate the risks. Because of the nature of the Funds, you should
consider your investment to be a long-term investment that typically provides
the best results when held for a number of years. Following are the chief risks
you assume when investing in these Funds. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

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. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.



                                                                              20

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 advisers Financial advisers provide advice to their clients--
analyzing their financial objectives and recommending appropriate funds or other
investments. Financial advisers are compensated for their services, generally
through sales commissions, and through 12b-1 and/or service fees deducted from
the fund's assets.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

About your account

Investing in the Funds
You can choose from a number of share classes for each Fund. Because each share
class has a different combination of sales charges, fees, and other features,
you should consult your financial adviser 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 4.75% that you pay when
   you buy the shares. The offering price for Class A shares includes the
   front-end sales charge.

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

o  You may qualify for other reduced sales charges, as described in "How to
   reduce your sales charge," and under certain circumstances the sales charge
   may be waived; please see the Statement of Additional Information.

o  Class A shares are also subject to an annual 12b-1 fee no greater than 0.30%
   of average daily net assets, which is lower than the 12b-1 fee for Class B
   and Class C shares.

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

   sales charge if you redeem your shares within six years after you buy them.

o  If you redeem Class B shares during the first two years after you buy them,
   the shares will be subject to a contingent deferred sales charge of 4%. The
   contingent deferred sales charge is 3% during the third and fourth years, 2%
   during the fifth year, 1% during the sixth year, and 0% thereafter.

o  Under certain circumstances the contingent deferred sales charge may be
   waived; please see the Statement of Additional Information.

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

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

o  Approximately eight 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 eighth anniversary of
   purchase, during which time Class B's higher 12b-1 fees apply.

o  You may purchase up to $250,000 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 a Fund. However, you will pay a contingent deferred
   sales charge of 1% if you redeem your shares within 12 months after you buy
   them.

o  Under certain circumstances the contingent deferred sales charge may be
   waived; please see the Statement of Additional Information.

o  Class C shares are subject to an annual 12b-1 fee which may not be greater
   than 1% 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 pay
   lower dividends than Class A 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.

Each share class of the Funds has adopted a separate 12b-1 plan that allows it
to pay distribution fees for the sales and distribution of its shares. Because
these fees are paid out of a 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.

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, 1818
Market Street, Philadelphia, PA 19103-3682. If you are making an initial

appropriate retirement plan application if you are opening a retirement account)
with your check.

                                                                              26

About your account (continued)

How to buy shares (continued)


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. 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 is $250, and you can make additional
investments of only $25. The minimum for an Education IRA is $500. The minimums
vary for retirement plans other than IRAs, Roth IRAs or Education IRAs.

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

We determine each Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in a Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market value.


Retirement plans
In addition to being an appropriate investment for your Individual Retirement
Account (IRA), Roth IRA and Education IRA, shares in the Funds 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 these Funds can play an important role in your
retirement planning or for details about group plans, please consult your
financial adviser, or call 800.523.1918.


                                                                              27

How to redeem shares

[GRAPHIC OMITTED: ILLUSTRATION OF A PERSON]

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

[GRAPHIC OMITTED: ILLUSTRATION OF AN ENVELOPE]

By mail
You can redeem your shares (sell them back to the fund) by mail by writing to:
Delaware Investments, 1818 Market Street, Philadelphia, PA 19103-3682. All
owners of the account must sign the request, and for redemptions of more than
$50,000, 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 an account.

[GRAPHIC OMITTED: ILLUSTRATION OF A TELEPHONE]

By telephone
You can redeem up to $50,000 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: ILLUSTRATION OF A JAGGED LINE]


By wire
You can redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account 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: ILLUSTRATION OF A KEYPAD]

Through automated shareholder services
You can 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

About your account (continued)

How to redeem shares (continued)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 p.m. Eastern time), you will receive the net asset value as determined on
the business day we receive your request. 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' net
asset value when you purchased them or their net asset value 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 required account
minimum of $1,000 ($250 for IRAs, Uniform Gift to Minors Act or Uniform
Transfers to Minors Act accounts or accounts with automatic investing plans,
$500 for Education IRAs) 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.



                                                                              29

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.


Wealth Builder Option
With the Wealth Builder Option you can arrange automatic monthly exchanges
between your shares in one or more Delaware Investments 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 fund in the
Delaware Investments family. 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 can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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 you
will pay any applicable sales charges 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 don't 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.



                                                                              30

About your account (continued)

Special services (continued)


MoneyLine(SM) On Demand Service
Through our MoneyLineSM On Demand Service, you or your financial adviser may
transfer money between your Fund account and your predesignated bank account by
telephone request. This service is not available for retirement plans, except
for purchases into IRAs. MoneyLine has a minimum transfer of $25 and a maximum
transfer of $50,000. 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.


Dividends, distributions and taxes
For each Fund, dividends, if any, are declared and paid monthly. Capital gains,
if any, are paid twice a year. We automatically reinvest all dividends and any
capital gains, unless you tell us otherwise.


Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from these Funds is the same whether you
reinvest your dividends or receive them in cash. Distributions from a Fund's
long-term capital gains are taxable as capital gains, while distributions from
short-term capital gains and net investment income are generally taxable as
ordinary income. Any capital gains may be taxable at different rates depending
on the length of time a Fund held the assets. In addition, you may be subject to
state and local taxes on distributions.


We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.

Certain management considerations


Investments by fund of funds
Each Fund accepts investments from the series portfolios of Delaware Group
Foundation Funds, a fund of funds. From time to time, a Fund may experience
large investments or redemptions due to allocations or rebalancings by
Foundation Funds. While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management.
For example, a 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 Foundation Funds and will attempt to minimize any adverse effects on the
Funds and Foundation Funds as a result of these transactions.




                                                                              32

(1) Commencement of operations; ratios have been annualized but total return has
    not been annualized.
(2) Total investment return is based on the change in net asset value of a share
    during the period and assumes reinvestment of distributions at net asset
    value and does not reflect the impact of a sales charge.
(3) Total return reflects an expense limitation in effect during the period.
(4) The average share outstanding method has been applied for per share
    information for the year ended July 31, 2000.

How to read the Financial highlights

Net investment income
Net investment income 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 (loss) on investments occurs when we sell an investment at a
profit, while a realized loss on investments 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
that we pay to shareholders, if any, would be listed under "Less dividends and
distributions-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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.

                                                                              35

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.

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.

See also Nationally recognized statistical ratings organization.

Capital

Capital appreciation
An increase in the value of an investment.

Capital gains distributions

commission.

Corporate bond

Diversification
The process of spreading investments among a number of different securities,
asset classes or investment styles to reduce the risks of investing.

Government securities
Securities issued by U.S. government or its agencies. They include Treasuries as
well as agency-backed securities such as Fannie Maes.

Inflation
The increase in the cost of goods and services over time. U.S. inflation is

mutual fund pursues.

Management fee
The amount paid by a mutual fund to the investment adviser for management
services, expressed as an annual percentage of the fund's average daily net
assets.

Market capitalization
The value of a corporation determined by multiplying the current market price of
a share of common stock by the number of shares held by shareholders. A
corporation with one million shares outstanding and the market price per share
of $10 has a market capitalization of $10 million.

Maturity
The length of time until a bond issuer must repay the underlying loan principal
to bondholders.

Profile:  Delaware Delchester Fund

What is the Fund's goal?
Delaware Delchester Fund seeks as high a level of current income as is
consistent with providing reasonable safety. Although the Fund will strive to
meet its goal, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in high-yielding corporate bonds rated BB or lower by
Standard and Poor's or similarly rated by another nationally recognized
statistical ratings organization (NRSRO). These are commonly known as high-yield
bonds or junk bonds and involve greater risks than investment grade bonds. We
may also invest in unrated bonds if we judge them to be of comparable quality.
We will select bonds primarily based on the income potential they offer and on
our evaluation of the bond issuers' ability to make interest payments and repay
principal.

We may also invest in equity securities, foreign government securities and
corporate bonds of foreign issuers. Though not expected to be a significant
component of our strategy under normal circumstances, we may also invest in
investment grade corporate bonds, U.S. government securities and high quality
commercial paper.

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. 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 declines in
bond prices, which can be caused by an adverse change in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. High-yield bonds are rated below investment grade and are subject to
greater risk that the issuer will be unable to make payments on interest and
principal, particularly under adverse economic conditions. Bonds of foreign
issuers are also subject to certain risks such as political and economic
instability, currency fluctuations and less stringent regulatory standards.

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

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.

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 adviser to
determine whether it is an appropriate choice for you.

Who should invest in the Fund
    o Investors looking for a fixed-income investment that offers potential for
      very high current income.
    o Investors with long-term financial goals.

Who should not invest in the Fund
    o Investors with short-term financial goals.
    o Investors who are unwilling to own an investment whose value may
      fluctuate, sometimes significantly, over the short term.

                                                                               3

How has Delaware Delchester Fund performed?

This bar chart and table can help you evaluate the risks of investing in the
Fund. We show how returns for the Fund's Institutional Class shares have varied
over the past ten calendar years, as well as the average annual returns for the
one-, five-, and ten-year periods. Delaware Delchester Fund's Institutional
Class commenced operations on June 1, 1992. Return information for the
Institutional Class for the periods prior to the time the Institutional Class
commenced operations is calculated by taking the performance of the Fund's Class
A shares and eliminating all sales charges that apply to Class A shares.
However, for those periods, no adjustment has been made to eliminate the impact
of 12b-1 plan payments, and performance may have been affected had such an
adjustment been made. The Fund's past performance is not necessarily an
indication of how it will perform in the future.

Profile: Delaware High-Yield Opportunities Fund

What is the Fund's goal?
Delaware High-Yield Opportunities Fund seeks total return and, as a secondary
objective, high current income. Although the Fund will strive to meet its goal,
there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in corporate bonds rated BB or lower by S&P or similarly
rated by another NRSRO. These are commonly known as high-yield bonds or junk
bonds and involve greater risks than investment grade bonds. The Fund will also
invest in unrated bonds we judge to be of comparable quality. Unrated bonds may
be more speculative in nature than rated bonds. The Fund may also invest in U.S.
and foreign government securities and corporate bonds of foreign issuers. In
selecting bonds for the portfolio, we evaluate the income provided by the bond
and the bond's appreciation potential as well as the issuer's ability to make
income and principal payments.

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. 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 declines in
bond prices, which can be caused by adverse changes in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. High-yield bonds are rated below investment grade and are subject to
greater risk that the issuer will be unable to make payments on interest and
principal, particular under adverse conditions. Bonds of foreign issuers are
also subject to certain risks such as political and economic instability,
currency fluctuations and less stringent regulatory standards.

How we manage the Funds

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

Our investment strategies
We analyze economic and market conditions, seeking to identify the securities or
market sectors that we think are the best investments for a particular fund.
Following are descriptions of how the portfolio managers pursue the Funds'
investment goals.

For both Delaware Delchester Fund and Delaware High-Yield Opportunities Fund, we
invest primarily in fixed-income securities that we believe will have a liberal
and consistent yield and will tend to reduce the risk of market fluctuations. We
expect to invest the majority of the Funds' assets primarily in high-yield bonds
or junk bonds, which involve greater risks than investment grade bonds. The
Funds may also invest in unrated bonds that we consider to have comparable
credit characteristics. Unrated bonds may be more speculative in nature than
rated bonds.

Before selecting high-yield corporate bonds, we carefully evaluate each
individual bond including its income potential and the size of the bond
issuance. The size of the issuance helps us evaluate how easily we may be able
to buy and sell the bond.

We also do a thorough credit analysis of the issuer to determine whether that
company has the financial ability to meet the bond's payments.

We maintain a well-diversified portfolio of high-yield bonds that represents
many different sectors and industries. Through diversification we can help to
reduce the impact that any individual bond might have on the portfolio should
the issuer have difficulty making payments.

Delaware Delchester Fund
Our primary goal for Delaware Delchester Fund is to provide high current income.
For this reason, the income potential of a bond is a key selection criteria.

It is our policy to invest at least 80% of our assets in corporate bonds, U.S.
government securities or commercial paper of companies rated A-1 or A-2 by S&P
or P-1 or P-2 by Moody's Investors Service, Inc. (which are two NRSROs). We are
required to invest primarily in corporate bonds rated BBB or below; however we
particularly emphasize those rated BB or B. We generally focus more on bonds
rated B in times of economic growth and more on bonds rated BB when the economy
appears to be slowing. The Fund also may invest in bonds of foreign issuers and
equity securities in pursuit of its objective.

Delaware High-Yield Opportunities Fund
Delaware High-Yield Opportunities Fund strives to provide total return, with
income as a secondary objective. Before purchasing a bond, we evaluate both the
income level and its potential for price appreciation. At least 65% of the
Fund's assets will be invested in corporate bonds rated at the time of purchase
as BB or lower by S&P or similarly rated by another NRSRO or, if unrated, that
we judge to be of comparable quality. The Fund also may invest in bonds of
foreign issuers in pursuit of its objective.

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

                                                                               9

The securities we typically invest in
Fixed-income securities generally offer the potential for greater income
payments than stocks, and also may provide capital appreciation.

Delaware Delchester Fund and Delaware High-Yield Opportunities Fund may also
invest in other income producing and non-income producing securities including
common stocks and preferred stocks, some of which may have convertible features
or attached warrants. Please see the Statement of Additional Information for
additional descriptions on these securities as well as those listed in the table
above.

Lending securities
Each Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for their use in security transactions. These
transactions, if any, may generate additional income for the Funds.

Borrowing from banks
Each Fund is permitted to borrow money but normally does not do so. As a
temporary measure for extraordinary purposes or to meet redemption requests, a
Fund may borrow up to one-third of the value of its assets. Borrowing money
could result in the Funds being unable to meet their investment objectives.

Purchasing securities on a when-issued or delayed delivery basis
Delaware Delchester Fund and Delaware High-Yield Opportunities Fund may buy or
sell securities on a when-issued or delayed delivery basis; that is, paying for
securities before delivery or taking delivery up to 45 days later. Each 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 each Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if a Fund sold and replaced securities
valued at 100% of its net assets within one year. High turnover can result in
increased transaction costs and tax liability for investors.

The risks of investing in the Funds
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 a Fund you should
carefully evaluate the risks. Because of the nature of the Funds, you should
consider your investment to be a long-term investment that typically provides
the best results when held for a number of years. Following are the chief risks
you assume when investing in these Funds. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

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. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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 or
sub-adviser 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
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.


                                                                              15

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.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

                                                                              16

About your account (continued)

How to buy shares (continued)

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

We determine each Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in each Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market value.


                                                                              19

How to redeem shares

[GRAPHIC OMITTED: ILLUSTRATION OF AN ENVELOPE]

By mail
You can redeem your shares (sell them back to the fund) by mail by writing to:
Delaware Investments, 1818 Market Street, Philadelphia, PA 19103-3682. All
owners of the account must sign the request, and for redemptions of more than
$50,000, you must include a signature guarantee for each owner. You can also fax
your written request to 215.255.8864. Signature guarantees are also required
when redemption proceeds are going to an address other than the address of
record on an account.

[GRAPHIC OMITTED: ILLUSTRATION OF A TELEPHONE]

By telephone
You can redeem up to $50,000 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: ILLUSTRATION OF A JAGGED LINE]

By wire
You can redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account the next business day after we receive your

Through your financial adviser
Your financial adviser can handle all the details of redeeming your shares. Your

                                                                              20

About your account (continued)

How to redeem shares (cont.)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 p.m. Eastern time), you will receive the net asset value as determined on
the business day we receive your request. 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.

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

Exchanges
You can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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
don't pay sales charges on shares that are 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. You may not exchange your shares for Class B and Class C shares of the
funds in the Delaware Investments family.

Dividends, distributions and taxes
For each Fund, dividends, if any, are declared and paid monthly. Capital gains,
if any, are paid twice a year. We automatically reinvest all dividends and any
capital gains.

Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from these Funds is the same whether you
reinvest your dividends or receive them in cash. Distributions from a Fund's
long-term capital gains are taxable as capital gains, while distributions from
short-term capital gains and net investment income are generally taxable as
ordinary income. Any capital gains may be taxable at different rates depending
on the length of time the Fund held the assets. In addition, you may be subject
to state and local taxes on distributions.

We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.


                                                                              21

Certain management considerations

Investments by fund of funds
Each Fund accepts investments from the series portfolios of Delaware Group
Foundation Funds, a fund of funds. From time to time, a Fund may experience
large investments or redemptions due to allocations or rebalancings by
Foundation Funds. While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management.
For example, a 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 Foundation Funds and will attempt to minimize any adverse effects on the
Funds and Foundation Funds as a result of these transactions.


                                                                              22

Financial highlights

The Financial highlights tables are intended to help you understand each Fund's
financial performance. All "per share" information reflects financial results
for a single Fund share. This information has been audited by Ernst & Young LLP,
whose reports, along with the Funds' financial statements, are included in the

How to read the Financial highlights

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

Net realized and unrealized gain (loss) on investments
A realized gain on investments occurs when we sell an investment at a profit,
while a realized loss on investments 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 that
we pay to shareholders, if any, would be listed under "Less dividends and
distributions-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, 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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.


                                                                              25

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.


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.
See also Nationally recognized statistical ratings organization.


Capital
The amount of money you invest.

Capital appreciation
An increase in the value of an investment.

Capital gains distributions
Payments to mutual fund shareholders of profits (realized gains) from the sale
of a fund's portfolio securities. Usually paid once a year; may be either
short-term gains or long-term gains.

Commission
The fee an investor pays to a financial adviser for investment advice and help
in buying or selling mutual funds, stocks, bonds or other securities.

Compounding
Earnings on an investment's previous earnings.

Consumer Price Index (CPI)
Measurement of U.S. inflation; represents the price of a basket of commonly
purchased goods.

Corporate bond
A debt security issued by a corporation. See Bond.

Depreciation
A decline in an investment's value.

Diversification
The process of spreading investments among a number of different securities,
asset classes or investment styles to reduce the risks of investing.

Dividend distribution
Payments to mutual fund shareholders of dividends passed along from the fund's
portfolio of securities.


                                                                              26

Government securities
Securities issued by U.S. government or its agencies. They include Treasuries as
well as agency-backed securities such as Fannie Maes.

Inflation
The increase in the cost of goods and services over time. U.S. inflation is

Investment goal
The objective, such as long-term capital growth or high current income, that a
mutual fund pursues.

Management fee
The amount paid by a mutual fund to the investment adviser for management
services, expressed as an annual percentage of the fund's average daily net
assets.

Market capitalization
The value of a corporation determined by multiplying the current market price of
a share of common stock by the number of shares held by shareholders. A
corporation with one million shares outstanding and the market price per share
of $10 has a market capitalization of $10 million.

Maturity
The length of time until a bond issuer must repay the underlying loan principal
to bondholders.


NASD Regulation, Inc. (NASDR(SM))

Profile: Delaware Strategic Income Fund

What is the Fund's goal?

The Fund seeks high current income and total return. Although the Fund will
strive to achieve its goal, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in bonds allocated among three sectors of the fixed income
market. These include:

o the High-Yield Sector, consisting of high-yielding, lower-rated or unrated
  fixed-income securities that we believe to be similarly rated issued by U.S.
  companies. (These involve higher risk and are commonly known as "junk
  bonds.");

o the Investment Grade Sector, consisting of investment grade debt obligations
  of U.S. companies and those issued or guaranteed by the U.S. government, its
  agencies or instrumentalities, or by U.S. companies; and
o the International Sector, consisting of bonds issued by foreign governments,
  their agencies and instrumentalities, as well as other fixed-income securities
  of issuers in foreign countries and denominated in foreign currencies. (An
  issuer is considered to be from the country where it is located, where the
  majority of its assets are or where it generates the majority of its operating
  income.)

We determine the amount of the Fund's assets that will be allocated to each of
the three sectors based on our analysis of economic and market conditions and
our assessment of the income and appreciation potential offered by each sector.
We periodically reallocate the Fund's assets.

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. 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 declines in
bond prices, which can be caused by an adverse change in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. The Fund is also subject to the special risks associated with
high-yield bond investing and with foreign investing. In particular, high-yield
bonds are rated below investment grade and are subject to greater risk that
issuers will be unable to make interest or principal payments, particularly
under adverse economic conditions.

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

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 long-term financial goals.
o Investors looking for an investment that offers professional allocation among
  key types of fixed-income securities.
o Investors looking for a fixed-income investment that offers potential for high
  current income and total return.

Who should not invest in the Fund
o Investors with short-term financial goals.
o Investors who are unwilling to own an investment whose value may fluctuate,
  sometimes significantly, over the short term.

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 adviser to
determine whether it is an appropriate choice for you.

                                                                               3

How has the Fund performed?

This bar chart and table can help you evaluate the risks of investing in the
Fund. We show how returns for the Fund's Class A shares have varied over the
past three calendar years, as well as the average annual returns of all shares
for one-year and lifetime periods. The Fund's past performance does not
necessarily indicate how it will perform in the future. The returns reflect an
expense limitation. The returns would be lower without the limitation.

[bar chart]

Year-by-year total return (Class A)

---------------------------------------
1997                             9.41%
---------------------------------------
1998                             2.24%
---------------------------------------
1999                            -2.47%
---------------------------------------

As of June 30, 2000, the Fund's Class A shares had a calendar year-to-date
return of -2.15%. During the periods illustrated in this bar chart, Class A's
highest quarterly return was 4.54% for the quarter ended June 30, 1997 and its
lowest quarterly return was -1.79% for the quarter ended June 30, 1999.

The maximum Class A sales charge of 4.75%, which is normally deducted when you
purchase shares, is not reflected in the total returns 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 shown in the table on page __ do include
the sales charge.

</TABLE>
The Fund's returns are compared to the performance of the Lehman Brothers
Aggregate Bond Index. You should remember that unlike the Fund, the index is
unmanaged and doesn't reflect the costs of operating a mutual fund, such as the
costs of buying, selling and holding securities. The index also does not include
foreign fixed-income securities or high-yield bonds, which are a significant
component of the Fund's strategy.

* If shares were not redeemed, the returns for Class B and Class C would be
  -3.22% and 3.11% for the one-year and lifetime periods, respectively.

                                                                               4

(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 adviser who is
    paid a commission, a contingent deferred sales charge will apply to certain
    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 two years after you buy them,
    you will pay a contingent deferred sales charge of 4%, which declines to 3%
    during the third and fourth years, 2% during the fifth year, 1% during the
    sixth year, and 0% thereafter.

(3) Class C shares redeemed within one year of purchase are subject to a 1%
    contingent deferred sales charge.

(4) The Board of Trustees set the 12b-1 plan expenses for the Fund's Class A
    shares at 0.25%. Expenses under the 12b-1 plan will not be more than 0.30%.

(5) The investment manager has contracted to waive fees and pay expenses through
    September 30, 2001 in order to prevent total operating expenses (excluding
    any 12b-1 expenses, taxes, interest, brokerage fees and extraordinary
    expenses) from exceeding 0.75% of average daily net assets.

(6) The Fund's actual rate of return may be greater or less than the
    hypothetical 5% return we use here. This example reflects the net operating
    expenses with expense waivers for year one and the total operating expenses
    without expense waivers for years two through ten.

(7) The Class B example reflects the conversion of Class B shares to Class A
    shares after approximately eight years. Information for the ninth and tenth
    years 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 think are the best investments for the Fund. Following
are descriptions of how the portfolio managers pursue 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.

Delaware Strategic Income Fund is a type of fixed-income fund that invests in
three distinct sectors of the fixed-income market as it pursues its investment
objective of providing high current income and total return.

Certain economic and market events may have a greater impact on certain types of
bonds. By spreading the portfolio assets among three key types of bonds, we
strive to reduce the affect that such events might have on the Fund.

The foundation of our strategy is the belief that when one or more bond sectors
are not performing well, the others may continue to provide high income and
appreciation potential, helping to support the Fund's performance.

Following are the three key sectors we focus on as well as our general
investment approach in each sector:

o U.S. government and high-quality corporate bonds are selected primarily on the
  basis of their income potential. In periods of slower U.S. economic growth,
  these bonds might also provide a stabilizing influence on the portfolio which
  could enhance total return.

o U.S. high-yield corporate bonds are primarily used to increase the portfolio's
  income potential. These bonds are of lower quality and involve the risk that
  the companies issuing them may not be able to pay interest or repay principal.
  However, we carefully select the high-yield bonds for the Fund after
  evaluating both the company's fundamental strength and the bond's liquidity.

o Foreign bonds are used to add diversification. Because foreign markets are
  often affected by different economic cycles than the U.S., foreign bonds may
  experience performance cycles that are different as well. In selecting foreign
  bonds for the Fund, we strive to manage the risk associated with foreign
  investing through a thorough analysis of the bond's issuer and the inflation
  trends in the country where the bond is issued.

In determining how much of the portfolio to allocate to each sector, we review
economic and market conditions and interest rate trends as well as the potential
risks and rewards associated with each sector. As little as 20% or as much as
60% of the Fund's assets may be invested in each fixed-income sector. In
addition, the Fund may invest up to 10% of its assets in U.S. equity securities.

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

                                                                               7

The securities we typically invest in
Fixed-income securities generally offer the potential for greater income
payments than stocks, and also may provide capital appreciation.

</TABLE>

Please see the Statement of Additional Information for additional descriptions
on these securities.

Lending securities
The Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for their use in security transactions. These
transactions, if any, may generate additional income for the Fund.

Borrowing from banks
The Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions. Borrowing money could result in the Fund being unable
to meet its investment objective. The Fund will not borrow money in excess of
one-third of the value of its net assets.

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.

Temporary defensive positions
We may hold a substantial part of the Fund's assets in cash or cash equivalents
as a temporary defensive strategy. To the extent it holds these securities, the
Fund may be unable to achieve its investment objective.

                                                                              11

Portfolio turnover
We anticipate that the Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if the Fund sold and replaced
securities valued at 100% of its net assets within one year. High turnover can
result in increased transaction costs and tax liability for investors.

                                                                              12

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. Following are the chief risks
you assume when investing in the Fund. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

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. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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.

Sub-adviser A sub-adviser is a company generally responsible for the management
of the fund's assets. Sub-advisers are selected and supervised by the investment
manager.

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

                                                                              18
<PAGE>

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
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.

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 advisers Financial advisers provide advice to their clients analyzing
their financial objectives and recommending appropriate funds or other
investments. Financial advisers are compensated for their services, generally
through sales commissions, and through 12b-1 and/or service fees deducted from
the fund's assets.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

                                                                              19

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 adviser 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 4.75% that you pay when
   you buy the shares. The offering price for Class A shares includes the
   front-end sales charge.

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

o  You may qualify for other reduced sales charges, as described in "How to
   reduce your sales charge," and under certain circumstances the sales charge
   may be waived; please see the Statement of Additional Information.

o  Class A shares are also subject to an annual 12b-1 fee no greater than 0.30%
   (currently 0.25%) of average daily net assets, which is lower than the 12b-1
   fee for Class B and Class C shares.

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

As shown below, there is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if your
financial adviser is paid a commission on your purchase, you will have to pay a limited contingent deferred sales charge of 1%
if you redeem these shares within the first year after your purchase and 0.50% if you redeem them within the second year,
unless a specific waiver of the charge applies.

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 six years after you buy them.

o  If you redeem Class B shares during the first two years after you buy them,
   the shares will be subject to a contingent deferred sales charge of 4%. The
   contingent deferred sales charge is 3% during the third and fourth years, 2%
   during the fifth year, 1% during the sixth year, and 0% thereafter.

o  Under certain circumstances the contingent deferred sales charge may be
   waived; please see the Statement of Additional Information.

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

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

o  Approximately eight 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% (currently
   0.25%). Conversion may occur as late as three months after the eighth
   anniversary of purchase, during which time Class B's higher 12b-1 fees apply.

o  You may purchase up to $250,000 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% if you redeem your shares within 12 months after you buy
   them.

o  Under certain circumstances the contingent deferred sales charge may be
   waived; please see the Statement of Additional Information.

o  Class C shares are subject to an annual 12b-1 fee which may not be greater
   than 1% 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 pay
   lower dividends than Class A 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.

Each share class of the Fund has adopted a separate 12b-1 plan that allows it to
pay distribution fees for the sales 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.


                                                                              21

About your account (continued)

How to buy shares (continued)

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. 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 is $250, and you can make additional
investments of only $25. The minimum for an Education IRA is $500. The minimums
vary for retirement plans other than IRAs, Roth IRAs or Education IRAs.

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

We determine the Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in the Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market value.

Retirement plans
In addition to being an appropriate investment for your Individual Retirement
Account (IRA), Roth IRA and Education IRA, 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 adviser, or call 800.523.1918.

By mail
You can redeem your shares (sell them back to the fund) by mail by writing to:
Delaware Investments, 1818 Market Street, Philadelphia, PA 19103-3682. All
owners of the account must sign the request, and for redemptions of more than
$50,000, 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 an account.

[GRAPHIC OMITTED: ILLUSTRATION OF A TELEPHONE]

By telephone
You can redeem up to $50,000 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: ILLUSTRATION OF A JAGGED LINE]

You can redeem $1,000 or more of your shares and have the proceeds deposited
directly to your bank account the next business day after we receive your
request. If you request a wire deposit, a bank wire fee may be deducted from

About your account (continued)

How to redeem shares (continued)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 p.m. Eastern time), you will receive the net asset value as determined on
the business day we receive your request. 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' net
asset value when you purchased them or their net asset value 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 required account
minimum of $1,000 ($250 for IRAs, Uniform Gift to Minors Act and Uniform
Transfers to Minor Act accounts or accounts with automatic investing plans, $500
for Education IRAs) 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.



                                                                              26

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.

Wealth Builder Option
With the Wealth Builder Option you can arrange automatic monthly exchanges
between your shares in one or more Delaware Investments 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 fund in the
Delaware Investments family. 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 can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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 you
will pay any applicable sales charges 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 don't 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.



                                                                              27

Special services (continued)

MoneyLine(SM) On Demand Service
Through our MoneyLineSM On Demand Service, you or your financial adviser may
transfer money between your Fund account and your predesignated bank account by
telephone request. This service is not available for retirement plans, except
for purchases into IRAs. MoneyLine has a minimum transfer of $25 and a maximum
transfer of $50,000. 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.

Dividends, distributions and taxes
Dividends, if any, are declared and paid monthly. Capital gains, if any, are
paid twice a year. We automatically reinvest all dividends and any capital
gains, unless you tell us otherwise.

Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from the Fund is the same whether you reinvest
your dividends or receive them in cash. Distributions from the Fund's long-term
capital gains are taxable as capital gains, while distributions from short-term
capital gains and net investment income are generally taxable as ordinary
income. Any capital gains may be taxable at different rates depending on the
length of time the Fund held the assets. In addition, you may be subject to
state and local taxes on distributions.

We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.



                                                                              28

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 (loss) on investments occurs when we sell an investment at a
profit, while a realized loss on investments 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
that we pay to shareholders, if any, is listed under "Less dividends and
distributions-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 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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.

                                                                              31

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.

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.
See also Nationally recognized statistical ratings organization.

Capital
The amount of money you invest.

Capital appreciation
An increase in the value of an investment.

Capital gains distributions
Payments to mutual fund shareholders of profits (realized gains) from the sale
of a fund's portfolio securities. Usually paid once a year; may be either
short-term gains or long-term gains.

Commission
The fee an investor pays to a financial adviser for investment advice and help
in buying or selling mutual funds, stocks, bonds or other securities.

Compounding
Earnings on an investment's previous earnings.

Consumer Price Index (CPI)
Measurement of U.S. inflation; represents the price of a basket of commonly
purchased goods.

Contingent deferred sales charge (CDSC)
Fee charged by some mutual funds when shares are redeemed (sold back to the
fund) within a set number of years; an alternative method for investors to
compensate a financial adviser for advice and service, rather than an up-front
commission.

Corporate bond
A debt security issued by a corporation. See Bond.

Depreciation
A decline in an investment's value.

Diversification
The process of spreading investments among a number of different securities,
asset classes or investment styles to reduce the risks of investing.

                                                                              32
<PAGE>
Dividend distribution

net assets. Operating expenses are the costs of running a mutual fund, including
management fees, offices, staff, equipment and expenses related to maintaining

from the fund's assets before any earnings are distributed to shareholders.

Fixed-income securities
With fixed-income securities, the money you originally invested is paid back at

corporate or municipal bonds, as well as money market securities, typically pay
a fixed rate of return (often referred to as interest). See Bond.

Government securities
Securities issued by U.S. government or its agencies. They include Treasuries as
well as agency-backed securities such as Fannie Maes.

Inflation
The increase in the cost of goods and services over time. U.S. inflation is
frequently measured by changes in the Consumer Price Index (CPI).

Investment goal
The objective, such as long-term capital growth or high current income, that a
mutual fund pursues.

Lehman Brothers Aggregate Bond Index
The Lehman Brothers Aggregate Bond Index is an index that measures the
performance of about 6,500 U.S. corporate and government bonds.

Management fee
The amount paid by a mutual fund to the investment adviser for management
services, expressed as an annual percentage of the fund's average daily net
assets.

Market capitalization
The value of a corporation determined by multiplying the current market price of
a share of common stock by the number of shares held by shareholders. A
corporation with one million shares outstanding and the market price per share
of $10 has a market capitalization of $10 million.

liquidation of assets. Preferred stocks also often pay dividends at a fixed rate
and are sometimes convertible into common stock.

Price-to-earnings ratio

Profile: Delaware Strategic Income Fund


What is the Fund's goal?
The Fund seeks high current income and total return. Although the Fund will
strive to achieve its goal, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in bonds allocated among three sectors of the fixed-income
market. These include:

o    the High-Yield Sector, consisting of high-yielding, lower-rated or unrated
     fixed-income securities that we believe to be similarly rated issued by
     U.S. companies. (These involve higher risk and are commonly known as "junk
     bonds.");
o    the Investment Grade Sector, consisting of investment grade debt
     obligations of U.S. companies and those issued or guaranteed by the U.S.
     government, its agencies or instrumentalities, or by U.S. companies; and
o    the International Sector, consisting of bonds issued by foreign
     governments, their agencies and instrumentalities, as well as other
     fixed-income securities of issuers in foreign countries and denominated in
     foreign currencies. (An issuer is considered to be from the country where
     it is located, where the majority of its assets are or where it generates
     the majority of its operating income.)

We determine the amount of the Fund's assets that will be allocated to each of
the three sectors based on our analysis of economic and market conditions and
our assessment of the income and appreciation potential offered by each sector.
We periodically reallocate the Fund's assets.


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. 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 declines in
bond prices, which can be caused by an adverse change in interest rates, adverse
economic conditions or poor performance from specific industries or bond
issuers. The Fund is also subject to the special risks associated with
high-yield bond investing and with foreign investing. In particular, high-yield
bonds are rated below investment grade and are subject to greater risk that
issuers will be unable to make interest or principal payments, particularly
under adverse economic conditions.


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


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 long-term financial goals.
o    Investors looking for an investment that offers professional allocation
     among key types of fixed-income securities.
o    Investors looking for a fixed-income investment that offers potential for
     high current income and total return.

Who should not invest in the Fund
o    Investors with short-term financial goals.
o    Investors who are unwilling to own an investment whose value may fluctuate,
     sometimes significantly, over the short term.

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 adviser to
determine whether it is an appropriate choice for you.


                                                                               3

How has the Fund performed?
This bar chart and table can help you evaluate the risks of investing in the
Fund. We show how returns have varied over the past three calendar years, as
well as the average annual returns for one-year and lifetime periods. The Fund's
past performance does not necessarily indicate how it will perform in the
future. The returns reflect an expense limitation. The returns would be lower
without the limitation.

The Fund's returns are compared to the performance of the Lehman Brothers
Aggregate Bond Index. You should remember that unlike the Fund, the index is
unmanaged and doesn't reflect the actual costs of operating a mutual fund, such
as the costs of buying, selling and holding securities. The index also does not
include foreign fixed-income securities or high-yield bonds, which are a
significant component of the Fund's strategy.

How we manage the Fund

Our investment strategies
We analyze economic and market conditions, seeking to identify the securities or
market sectors that we think are the best investments for the Fund. Following
are descriptions of how the portfolio managers pursue 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.

Delaware Strategic Income Fund is a type of fixed-income fund that invests in
three distinct sectors of the fixed-income market as it pursues its investment
objective of providing high current income and total return.

Certain economic and market events may have a greater impact on certain types of
bonds. By spreading the portfolio assets among three key types of bonds, we
strive to reduce the affect that such events might have on the Fund.

The foundation of our strategy is the belief that when one or more bond sectors
are not performing well, the others may continue to provide high income and
appreciation potential, helping to support the Fund's performance.

Following are the three key sectors we focus on as well as our general
investment approach in each sector:

o    U.S. government and high-quality corporate bonds are selected primarily on
     the basis of their income potential. In periods of slower U.S. economic
     growth, these bonds might also provide a stabilizing influence on the
     portfolio which could enhance total return.

o    U.S. high-yield corporate bonds are primarily used to increase the
     portfolio's income potential. These bonds are of lower quality and involve
     the risk that the companies issuing them may not be able to pay interest or
     repay principal. However, we carefully select the high-yield bonds for the
     Fund after evaluating both the company's fundamental strength and the
     bond's liquidity.

o    Foreign bonds are used to add diversification. Because foreign markets are
     often affected by different economic cycles than the U.S., foreign bonds
     may experience performance cycles that are different as well. In selecting
     foreign bonds for the Fund, we strive to manage the risk associated with
     foreign investing through a thorough analysis of the bond's issuer and the
     inflation trends in the country where the bond is issued.

In determining how much of the portfolio to allocate to each sector, we review
economic and market conditions and interest rate trends as well as the potential
risks and rewards associated with each sector. As little as 20% or as much as
60% of the Fund's assets may be invested in each fixed-income sector. In
addition, the Fund may invest up to 10% of its assets in U.S. equity securities.


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




                                                                               6

</TABLE>

Please see the Statement of Additional Information for additional descriptions
on these securities.

Lending securities
The Fund may lend up to 25% of its assets to qualified brokers, dealers and
institutional investors for their use in security transactions. These
transactions, if any, may generate additional income for the Fund.

Borrowing from banks
The Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions. Borrowing money could result in the Fund being unable
to meet its investment objective. The Fund will not borrow money in excess of
one-third of the value of its net assets.

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.

Temporary defensive positions
We may hold a substantial part of the Fund's assets in cash or cash equivalents
as a temporary defensive strategy. To the extent it holds these securities, the
Fund may be unable to achieve its investment objective.

                                                                              10

Portfolio turnover
We anticipate that the Fund's annual portfolio turnover may be greater than
100%. A turnover rate of 100% would occur if the Fund sold and replaced
securities valued at 100% of its net assets within one year. High turnover can
result in increased transaction costs and tax liability for investors.

                                                                              11

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. Following are the chief risks
you assume when investing in the Fund. Please see the Statement of Additional
Information for further discussion of these risks and other risks not discussed
here.

fund. At least 40% of the Board of Trustees must be independent of the fund's
investment manager and distributor. These independent fund 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.

Sub-adviser A sub-adviser is a company generally responsible for the management
of the fund's assets. Sub-advisers are selected and supervised by the investment
manager.

Portfolio managers Portfolio managers are employed by the investment manager or
sub-adviser 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.

                                                                              17
<PAGE>

Distributor Most mutual funds continuously offer new shares to the public
through distributors who are regulated as broker-dealers and are subject to NASD
Regulation, Inc. (NASDR(SM)) rules governing mutual fund sales practices.

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.

Shareholders Like shareholders of other companies, mutual fund shareholders have
specific voting rights, including the right to elect trustees. 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 objectives or policies
must also seek shareholder approval.

About your account (continued)

How to buy shares (continued)

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

We determine the Fund's net asset value (NAV) per share at the close of regular
trading of the New York Stock Exchange each business day that the Exchange is
open. We calculate this value by adding the market value of all the securities
and assets in the Fund's portfolio, deducting all liabilities, and dividing the
resulting number by the number of shares outstanding. The result is the net
asset value per share. We price securities and other assets for which market
quotations are 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. Any fixed-income securities that
have a maturity of less than 60 days we price at amortized cost. For all other
securities, we use methods approved by the Board of Trustees that are designed
to price securities at their fair market value.

                                                                              21

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

                                                                              22

About your account (continued)

How to redeem shares (cont.)

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
before the close of regular trading on the New York Stock Exchange (normally
4:00 pm Eastern time), you will receive the net asset value as determined on the
business day we receive your request. 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.

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 can exchange all or part of your shares for shares of the same class in
another Delaware Investments 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
don't pay sales charges on shares that are 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. You may not exchange your shares for Class B and Class C shares of the
funds in the Delaware Investments family.

Dividends, distributions and taxes
Dividends, if any, are declared and paid monthly. Capital gains, if any,
are paid twice a year. We automatically reinvest all dividends and any capital
gains.

Tax laws are subject to change, so we urge you to consult your tax adviser about
your particular tax situation and how it might be affected by current tax law.
The tax status of your dividends from the Fund is the same whether you reinvest
your dividends or receive them in cash. Distributions from the Fund's long-term
capital gains are taxable as capital gains, while distributions from short-term
capital gains and net investment income are generally taxable as ordinary
income. Any capital gains may be taxable at different rates depending on the
length of time the Fund held the assets. In addition, you may be subject to
state and local taxes on distributions.

We will send you a statement each year by January 31 detailing the amount and
nature of all dividends and capital gains that you were paid for the prior year.


                                                                              23

How to read the Financial highlights

Net investment income
Net investment income 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 (loss) on investments occurs when we sell an investment at a
profit, while a realized loss on investments 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
that we pay to shareholders, if any, would be listed under "Less dividends and
distributions-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 the Fund. In calculating this figure for the financial highlights
table, we include fee waivers 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 class 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 to average net assets
We determine this ratio by dividing net investment income by average net assets.

Portfolio turnover
This figure tells you the amount of trading activity in a fund's portfolio. For
example, a fund with a 50% turnover has bought and sold half of the value of its
total investment portfolio during the stated period.

                                                                              25

[begin 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.

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 is
inversely related to current interest rates. When interest rates rise, bond
prices fall, and when interest rates fall, bond prices rise.

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.
See also Nationally recognized statistical ratings organization.

Capital
The amount of money you invest.

Capital appreciation
An increase in the value of an investment.

Capital gains distributions
Payments to mutual fund shareholders of profits (realized gains) from the sale
of a fund's portfolio securities. Usually paid once a year; may be either
short-term gains or long-term gains.

Commission

in buying or selling mutual funds, stocks, bonds or other securities.

Compounding
Earnings on an investment's previous earnings.

Consumer Price Index (CPI)

purchased goods.

Corporate bond
A debt security issued by a corporation. See Bond.

Depreciation
A decline in an investment's value.

Diversification
The process of spreading investments among a number of different securities,
asset classes or investment styles to reduce the risks of investing.

Dividend distribution
Payments to mutual fund shareholders of dividends passed along from the fund's
portfolio of securities.

                                                                              26
<PAGE>

Duration
A measurement of a fixed-income investment's price volatility. The larger the
number, the greater the likely price change for a given change in interest
rates.

Expense ratio
A mutual fund's total operating expenses, expressed as a percentage of its total
net assets. Operating expenses are the costs of running a mutual fund, including
management fees, offices, staff, equipment and expenses related to maintaining
the fund's portfolio of securities and distributing its shares. They are paid
from the fund's assets before any earnings are distributed to shareholders.

Financial adviser

Fixed-income securities
With fixed-income securities, the money you originally invested is paid back at
a pre-specified maturity date. These securities, which include government,
corporate or municipal bonds, as well as money market securities, typically pay
a fixed rate of return (often referred to as interest). See Bond.

Government securities
Securities issued by U.S. government or its agencies. They include Treasuries as
well as agency-backed securities such as Fannie Maes.

Inflation
The increase in the cost of goods and services over time. U.S. inflation is
frequently measured by changes in the Consumer Price Index (CPI).

Investment goal
The objective, such as long-term capital growth or high current income, that a
mutual fund pursues.

Lehman Brothers Aggregate Bond Index
The Lehman Brothers Aggregate Bond Index is an index that measures the
performance of about 6,500 U.S. corporate and government bonds.

Management fee
The amount paid by a mutual fund to the investment adviser for management
services, expressed as an annual percentage of the fund's average daily net
assets.

Market capitalization
The value of a corporation determined by multiplying the current market price of
a share of common stock by the number of shares held by shareholders. A
corporation with one million shares outstanding and the market price per share
of $10 has a market capitalization of $10 million.

Maturity
The length of time until a bond issuer must repay the underlying loan principal
to bondholders.

NASD Regulation, Inc. (NASDR(SM))
The independent subsidiary of the National Association of Securities Dealers,
Inc. responsible for regulating the securities industry.

Nationally recognized statistical ratings organization  (NRSRO)
A company that assesses the credit quality of bonds, commercial paper, preferred
and common stocks and municipal short-term issues, rating the probability that

liquidation of assets. Preferred stocks also often pay dividends at a fixed rate
and are sometimes convertible into common stock.

Price-to-earnings ratio
A measure of a stock's value calculated by dividing the current market price of
a share of stock by its annual earnings per share. A stock selling for $100 per
share with annual earnings per share of $5 has a P/E of 20.

INVESTMENT OBJECTIVES AND POLICIES

Investment Restrictions

         Fundamental Investment Restrictions--Each Fund has the following
investment restrictions which may not be amended without approval of a majority
of the outstanding voting securities, which is the lesser of more than 50% of
the outstanding voting securities of the Fund, or 67% of the voting securities
of that Fund present at a shareholder meeting if 50% or more of the voting
securities are present in person or represented by proxy. The percentage
limitations contained in the restrictions and policies set forth herein apply at
the time a Fund purchases securities.

A Fund may not:

         1. Make investments that will result in the concentration (as that term
may be defined in the Investment Company Act of 1940 (the "1940 Act"), any rule
or order thereunder, or U.S. Securities and Exchange Commission ("SEC") staff
interpretation thereof) of its investments in the securities of issuers
primarily engaged in the same industry, provided that this restriction does not
limit a Fund from investing in obligations issued or guaranteed by the U.S.
government, its agencies or instrumentalities, or in tax-exempt securities or
certificates of deposit.


         2. Borrow money or issue senior securities, except as the 1940 Act, any
rule or order thereunder, or SEC staff interpretation thereof, may permit.

         3. Underwrite the securities of other issuers, except that a Fund may
engage in transactions involving the acquisition, disposition or resale of its
portfolio securities, under circumstances where it may be considered to be an
underwriter under the Securities Act of 1933 (the "1933 Act").

         4. Purchase or sell real estate, unless acquired as a result of
ownership of securities or other instruments and provided that this restriction
does not prevent a Fund from investing in issuers which invest, deal or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests therein.

         5. Purchase or sell physical commodities, unless acquired as a result
of ownership of securities or other instruments and provided that this
restriction does not prevent a Fund from engaging in transactions involving
futures contracts and options thereon or investing in securities that are
secured by physical commodities.


                                                                               3

<PAGE>


         6. Make loans, provided that this restriction does not prevent a Fund
from purchasing debt obligations, entering into repurchase agreements, loaning
its assets to broker/dealers or institutional investors and investing in loans,
including assignments and participation interests.

         Non-Fundamental Investment Restrictions--In addition to the fundamental
policies and investment restrictions described above, and the various general
investment policies described in the Prospectuses, each Fund will be subject to
the following investment restrictions, which are considered non-fundamental and
may be changed by the Board of Trustees without shareholder approval.

         1. Each Fund is permitted to invest in other investment companies,
including open-end, closed-end or unregistered investment companies, either
within the percentage limits set forth in the 1940 Act, any rule or order
thereunder, or SEC staff interpretation thereof, or without regard to percentage
limits in connection with a merger, reorganization, consolidation or other
similar transaction. However, a Fund may not operate as a "fund of funds" which
invests primarily in the shares of other investment companies as permitted by
Section 12(d)(1)(F) or (G) of the 1940 Act, if its own shares are utilized as
investments by such a "fund of funds. "

         2. No Fund may invest more than 15% of its net assets in securities
which it can not sell or dispose of in the ordinary course of business within
seven days at approximately the value at which a Fund has valued the investment.

Following are additional non-fundamental investment restrictions for the Funds:

Delaware Delchester Fund

         1. Delaware Delchester Fund will not invest more than 5% of the value
of its assets in securities of any one company (except U.S. government bonds) or

         2. Delaware Delchester Fund will not invest for the purpose of
acquiring control of any company.

         3. Delaware Delchester Fund will not purchase or retain securities of a
company which has an officer or director who is an officer or trustee of Income
Funds, or an officer, trustee or partner of the Delaware Management Company (the
"Manager") if, to the knowledge of the Fund, one or more of such persons owns
beneficially more than 1/2 of 1% of the shares of the company, and in the
aggregate more than 5% thereof.

         4. Delaware Delchester Fund will not invest in securities of other
investment companies.

         5. Delaware Delchester Fund will not make any investment in real
estate. This restriction does not preclude the Fund's purchase of securities

property.

         7. Delaware Delchester Fund will not buy or sell commodities or

<PAGE>



         8. Delaware Delchester Fund will not borrow money in excess of 10% of
the value of its assets and then only as a temporary measure for extraordinary
or emergency purposes. Any borrowing will be done from a bank and to the extent
that such borrowing exceeds 5% of the value of the Fund's assets, asset coverage
of at least 300% is required. In the event that such asset coverage shall at any
time fall below 300%, the Fund shall, within three days thereafter (not
including Sundays and holidays) or such longer period as the SEC may prescribe
by rules and regulations, reduce the amount of its borrowings to an extent that
the asset coverage of such borrowings shall be at least 300%. The Fund shall not
issue senior securities as defined in the 1940 Act, except for notes to banks.

         9. Delaware Delchester Fund will not make loans. However, (i) the
purchase of a portion of an issue of publicly distributed bonds, debentures or
other securities, or of other securities authorized to be purchased by the
Fund's investment policies, whether or not the purchase was made upon the
original issuance of the securities, and the entry into "repurchase agreements"
are not to be considered the making of a loan by the Fund; and (ii) the Fund may
loan up to 25% of its assets to qualified broker/dealers or institutional
investors for their use relating to short sales and other security transactions.

         10. Delaware Delchester Fund will not invest in the securities of
companies which have a record of less than three years' continuous operation,
including any predecessor company or companies, if such purchase at the time
thereof would cause more than 5% of the total Fund assets to be invested in the
securities of such company or companies.

         11. Delaware Delchester Fund will not act as an underwriter of
securities of other issuers, except that the Fund may acquire restricted or not
readily marketable securities under circumstances where, if such securities are
sold, the Fund might be deemed to be an underwriter for purposes of the 1933
Act.

         12. No long or short positions on shares of the Fund may be taken by
Income Fund's officers, trustees or any of its affiliated persons. Such persons
may buy shares of the Fund for investment purposes, however, as described under
Purchasing Shares.

         13. Delaware Delchester Fund will not invest more than 25% of its
assets in any one particular industry.

voting securities of any one company.

         2. Delaware Strategic Income Fund will not make any investment in real

companies that deal in real estate, or the investment in securities secured by

                                                                               5

value of its total assets in securities of issuers all of which conduct their

         9. Delaware Strategic Income Fund will not invest for the purpose of
acquiring control of any company.

         10. Delaware Strategic Income Fund will not invest in securities of

the knowledge of the Fund, one or more of such persons beneficially owns in the
aggregate more than 5% thereof.

         12. Delaware Strategic Income Fund will not invest in the securities of
companies which have a record of less than three years' continuous operation,

partnerships or oil, gas and other mineral leases. In addition, Delaware

         The following provides additional information regarding the Funds'
investment policies.

Delaware Delchester Fund
         In investing for income and safety of principal, Delaware Delchester
Fund's emphasis in selection will be on securities having a liberal and
consistent yield and those tending to reduce the risk of market fluctuations.
The types of securities in which Delaware Delchester Fund invests are subject to
price fluctuations particularly due to changes in interest rates and economic
conditions. The Manager will seek to achieve Delaware Delchester Fund's
objective by investing at least 80% of the Fund's assets at time of purchase in:

         1. Corporate Bonds. The Fund will invest in both rated and unrated
bonds. Unrated bonds may be more speculative in nature than rated bonds; or

         2. Government Securities. Securities of, or guaranteed by, the U.S.
government, its agencies or instrumentalities; or

         3. Commercial Paper. Commercial paper of companies having, at the time
of purchase, an issue of outstanding debt securities rated as described above or
commercial paper rated A-1 or A-2 by Standard & Poor's ("S&P") or rated P-1 or
P-2 by Moody's Investors Service, Inc. ("Moody's") or similarly rated by other
rating agencies.

         As a matter of practice, Delaware Delchester Fund has consistently
invested more than 80% of its assets in such securities. The Fund may invest up
to 20% of its assets in equity securities, including common stocks and preferred
stocks, some of which may have convertible features or attached warrants.
Additionally, in unusual market conditions, in order to meet redemption
requests, for temporary defensive purposes, and pending investment, the Fund may
hold a substantial portion of its assets in cash or short-term obligations for
an appreciable period of time when market conditions warrant and the Fund is
anticipating higher interest rates. Currently, Delaware Delchester Fund's assets
are invested primarily in unrated bonds and bonds rated BB or lower by S&P or Ba
or lower by Moody's.

Delaware Strategic Income Fund

         The Manager will seek to achieve this objective by allocating the
Fund's investments principally among the following three sectors of the
fixed-income securities markets:

            (1) a High-Yield Sector, consisting of high-yielding, lower-rated or
unrated fixed-income securities issued by U.S. companies;

            (2) an Investment Grade Sector, consisting of investment grade debt
obligations issued or guaranteed by the U.S. government, its agencies or
instrumentalities, or by U.S. companies; and



                                                                               8
<PAGE>




            (3) an International Sector, consisting of obligations of foreign
governments, their agencies and instrumentalities, and other fixed-income
securities of issuers in foreign countries and denominated in foreign
currencies.

         The Manager will determine the amount of assets of the Fund that will
be allocated to each of the three sectors in which the Fund will invest, based
on its analysis of economic and market conditions and its assessment of the
returns and potential for appreciation that can be achieved from investment in
each of the three sectors. The Manager will periodically reallocate the Fund's
assets as it deems necessary, and as little as 20% and as much as 60% of the
Fund's assets among sectors may be invested in each fixed-income sector. In
addition, the Fund may invest up to 10% of its assets in U.S. equity securities.

Delaware High-Yield Opportunities Fund
         The types of securities in which Delaware High-Yield Opportunities Fund
invests are subject to price fluctuations particularly due to changes in
interest rates and economic conditions. The Manager will seek to achieve
Delaware High-Yield Opportunities Fund's objective by investing at least 65% of
the Fund's assets at time of purchase in corporate bonds rated BB or lower by
S&P or Ba or lower by Moody's or similarly rated by other rating agencies, and
in unrated bonds judged to be of comparable quality by the Manager. Unrated
bonds may be more speculative in nature than rated bonds.

         The Fund may also invest in securities of, or guaranteed by, the U.S.
and foreign governments, their agencies or instrumentalities and commercial
paper of companies having, at the time of purchase, an issue of outstanding debt
securities rated as described above or commercial paper rated A-1 or A-2 by S&P
or rated P-1 or P-2 by Moody's or similarly rated by other rating agencies, and
in unrated paper judged to be of comparable quality by the Manager.

         In addition to income-producing securities as described in the
Prospectuses, the Fund may make limited use of non-income producing equity
securities, such as, but not limited to, common stock. Typically, the Fund's
investments in non-income producing equity securities will be less than 5% of
the Fund's total assets.

Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund

         The types of securities in which each Fund invests are subject to price
fluctuations particularly due to changes in interest rates and economic
conditions. The Manager will seek to achieve each Fund's objective by investing
in investment grade corporate bonds. Each Fund may also invest in corporate
bonds rated BB by S&P or Ba by Moody's or similarly rated by other rating
agencies, and in unrated bonds judged to be of comparable quality by the
Manager. Unrated bonds may be more speculative in nature than rated bonds.

         Each Fund may also invest in securities of, or guaranteed by, the U.S.
and foreign governments, their agencies or instrumentalities and commercial
paper of companies having, at the time of purchase, an issue of outstanding debt
securities rated as described above or commercial paper rated A-1 or A-2 by S&P
or rated P-1 or P-2 by Moody's or similarly rated by other rating agencies, and
in unrated paper judged to be of comparable quality by the Manager.

         Appendix A - Ratings in this Part B describes the ratings of S&P and
Moody's.

Duration
         Most debt obligations provide interest (coupon) payments in addition to
a final (par) payment at maturity. Some obligations also have call provisions.
Depending on the relative magnitude of these payments and the nature of the call
provisions, the market values of debt obligations may respond differently to
changes in the level and structure of interest rates. Traditionally, a debt



                                                                               9
<PAGE>


security's term-to-maturity has been used as a proxy for the sensitivity of the
security's price to changes in interest rates (which is the interest rate risk
or volatility of the security). However, term-to-maturity measures only the time
until a debt security provides its final payment, taking no account of the
pattern of the security's payments prior to maturity.

         Duration is a measure of the expected life of a fixed income security
that was developed as a more precise alternative to the concept of
term-to-maturity. Duration incorporates a bond's yield, coupon interest
payments, final maturity and call features into one measure. Duration is one of
the fundamental tools used by the Manager in the selection of fixed income
securities. Duration is a measure of the expected life of a fixed income
security on a present value basis. Duration takes the length of the time
intervals between the present time and the time that the interest and principal
payments are scheduled or, in the case of a callable bond, expected to be
received, and weights them by the present values of the cash to be received at
each future point in time. For any fixed income security with interest payments
occurring prior to the payment of principal, duration is always less than
maturity. In general, all other factors being the same, the lower the stated or
coupon rate of interest of a fixed income security, the longer the duration of
the security; conversely, the higher the stated or coupon rate of interest of a
fixed income security, the shorter the duration of the security.

         There are some situations where even the standard duration calculation
does not properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon reset. Another example where the interest rate exposure is not properly
captured by duration is the case of mortgage pass-through securities. The stated
final maturity of such securities is generally 30 years, but current prepayment
rates are more critical in determining the securities' interest rate exposure.
In these and other similar situations, the Manager will use sophisticated
analytical techniques that incorporate the economic life of a security into the
determination of its interest rate exposure.

High-Yield, High Risk Securities
         Investing in so-called "high-yield" or "high risk" securities entails
certain risks, including the risk of loss of principal, which may be greater
than the risks involved in investment grade securities, and which should be
considered by investors contemplating an investment in the Funds. Such
securities are sometimes issued by companies whose earnings at the time of
issuance are less than the projected debt service on the high-yield securities.
The risks include the following:

         A. Youth and Volatility of the High-Yield Market--Although the market
for high-yield securities has been in existence for many years, including
periods of economic downturns, the high-yield market grew rapidly during the
long economic expansion which took place in the United States during the 1980s.
During that economic expansion, the use of high-yield debt securities to fund
highly leveraged corporate acquisitions and restructurings increased
dramatically. As a result, the high-yield market grew substantially during that
economic expansion. Although experts disagree on the impact recessionary periods
have had and will have on the high-yield market, some analysts believe a
protracted economic downturn would severely disrupt the market for high-yield
securities, would adversely affect the value of outstanding bonds and would
adversely affect the ability of high-yield issuers to repay principal and
interest. Those analysts cite volatility experienced in the high-yield market in
the past as evidence for their position. It is likely that protracted periods of
economic uncertainty would result in increased volatility in the market prices
of high-yield securities, an increase in the number of high-yield bond defaults
and corresponding volatility in a Fund's net asset value.

         B. Liquidity and Valuation--The secondary market for high-yield
securities is currently dominated by institutional investors, including mutual
funds and certain financial institutions. There is generally no established
retail secondary market for high-yield securities. As a result, the secondary
market for high-yield securities is more limited and less liquid than other
secondary securities markets. The high-yield secondary market is particularly


                                                                              10
<PAGE>

susceptible to liquidity problems when the institutions which dominate it
temporarily cease buying such securities for regulatory, financial or other
reasons, such as the savings and loan crisis. A less liquid secondary market may
have an adverse effect on a Fund's ability to dispose of particular issues, when
necessary, to meet a Fund's liquidity needs or in response to a specific
economic event, such as the deterioration in the creditworthiness of the issuer.
In addition, a less liquid secondary market makes it more difficult for a Fund
to obtain precise valuations of the high-yield securities in its portfolio.
During periods involving such liquidity problems, judgment plays a greater role
in valuing high-yield securities than is normally the case. The secondary market
for high-yield securities is also generally considered to be more likely to be
disrupted by adverse publicity and investor perceptions than the more
established secondary securities markets. Privately placed high-yield securities
are particularly susceptible to the liquidity and valuation risks outlined
above.

         C. Legislative and Regulatory Action and Proposals--There are a variety
of legislative actions which have been taken or which are considered from time
to time by the United States Congress which could adversely affect the market
for high-yield bonds. For example, Congressional legislation limited the
deductibility of interest paid on certain high-yield bonds used to finance
corporate acquisitions. Also, Congressional legislation has, with some
exceptions, generally prohibited federally-insured savings and loan institutions
from investing in high-yield securities. Regulatory actions have also affected
the high-yield market. For example, many insurance companies have restricted or
eliminated their purchases of high-yield bonds as a result of, among other
factors, actions taken by the National Association of Insurance Commissioners.
If similar legislative and regulatory actions are taken in the future, they
could result in further tightening of the secondary market for high-yield issues
and could reduce the number of new high-yield securities being issued.

         Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund
may invest up to 20% of its net assets in securities rated BB by S&P or Ba by
Moody's.

Zero Coupon and Pay-In-Kind Bonds
         The credit risk factors pertaining to lower rated securities also apply
to lower rated zero coupon, deferred interest and pay-in-kind bonds. These bonds
carry an additional risk in that, unlike bonds that pay interest throughout the
period to maturity, a Fund will realize no cash until the cash payment date and,
if the issuer defaults, the Fund may obtain no return at all on its investment.
Zero coupon, deferred interest and pay-in-kind bonds involve additional special
considerations.

         Zero coupon or deferred interest securities are debt obligations that
do not entitle the holder to any periodic payments of interest prior to maturity
or a specified date when the securities begin paying current interest (the "cash
payment date") and therefore are generally issued and traded at a discount from
their face amounts or par value. The discount varies depending on the time
remaining until maturity or cash payment date, prevailing interest rates,
liquidity of the security and the perceived credit quality of the issuer. The
discount, in the absence of financial difficulties of the issuer, typically
decreases as the final maturity or cash payment date of the security approaches.
The market prices of zero coupon securities are generally more volatile than the
market prices of securities that pay interest periodically and are likely to
respond to changes in interest rates to a greater degree than do non-zero coupon
or deferred interest securities having similar maturities and credit quality.
Current federal income tax law requires that a holder of a zero coupon security
report as income each year the portion of the original issue discount on the
security that accrues that year, even though the holder receives no cash
payments of interest during the year.

         Pay-in-kind bonds are securities that pay interest through the issuance
of additional bonds. The Fund will be deemed to receive interest over the life
of these bonds and be treated as if interest were paid on a current basis for
federal income tax purposes, although no cash interest payments are received by
the Fund until the cash payment date or until the bonds mature. Accordingly,

                                                                              11
<PAGE>

during periods when the Fund receive no cash interest payments on its zero
coupon securities or deferred interest or pay-in-kind bonds, it may be required
to dispose of portfolio securities to meet the distribution requirements and
these sales may be subject to the risk factors discussed above. The Fund is not
limited in the amount of its assets that may be invested in these types of
securities.

Foreign and Emerging Markets Securities
         Each Fund may invest in foreign and emerging markets securities.
Investors should recognize that investing in foreign issuers, including issuers
located in emerging market countries, involves certain considerations which are
not typically associated with investing in United States issuers. Since the
stocks of foreign companies are frequently denominated in foreign currencies,
and since Delaware Strategic Income Fund may temporarily hold uninvested
reserves in bank deposits in foreign currencies, the Fund will be affected
favorably or unfavorably by changes in currency rates and in exchange control
regulations, and may incur costs in connection with conversions between various
currencies. The investment policies of Delaware Strategic Income Fund permit it
to enter into forward foreign currency exchange contracts in order to hedge the
Fund's holdings and commitments against changes in the level of future currency
rates. Such contracts involve an obligation to purchase or sell a specific
currency at a future date at a price set at the time of the contract.

         There are a number of risks involved in investing in foreign
securities. For example, the assets and profits appearing on the financial
statements of a developing or emerging country issuer may not reflect its
financial position or results of operations in the way they would be reflected
had the financial statements been prepared in accordance with United States
generally accepted accounting principles. Also, for an issuer that keeps
accounting records in local currency, inflation accounting rules may require for
both tax and accounting purposes, that certain assets and liabilities be
restated on the issuer's balance sheet in order to express items in terms of
currency or constant purchasing power. Inflation accounting may indirectly
generate losses on profits.

         With respect to a Fund's investment in foreign government securities,
there is the risk that a foreign governmental issuer may default on its
obligations. If such a default occurs, the Fund may have limited effective legal
recourse against the issuer and/or guarantor. Remedies must, in some cases, be
pursued in the courts of the defaulting party itself, and the ability of the
holder of foreign government and government-related debt securities to obtain
recourse may be subject to the political climate in the relevant country. In
addition, no assurance can be given that the holders of commercial bank debt
will not contest payments to the holders of other foreign government and
government-related debt obligations in the event of default under their
commercial bank loan agreements.

         The issuers of the foreign government and government-related debt
securities in which Delaware Strategic Income Fund expects to invest have in the
past experienced substantial difficulties in servicing their external debt
obligations, which have led to defaults on certain obligations and the
restructuring of certain indebtedness. Restructuring arrangements have included,
among other things, reducing and rescheduling interest and principal payments by
negotiating new or amended credit agreements or converting outstanding principal
and unpaid interest to Brady Bonds, and obtaining new credit to finance interest
payments. Holders of certain foreign government and government-related
high-yield securities may be requested to participate in the restructuring of
such obligations and to extend further loans to their issuers. There can be no
assurance that the Brady Bonds and other foreign government and
government-related securities in which the Fund may invest will not be subject
to similar defaults or restructuring arrangements which may adversely affect the
value of such investments. Furthermore, certain participants in the secondary
market for such debt may be directly involved in negotiating the terms of these
arrangements and may therefore have access to information not available to other
market participants.


                                                                              12
<PAGE>

         There has been in the past, and there may be again in the future, an
interest equalization tax levied by the United States in connection with the
purchase of foreign securities such as those purchased by these Funds. Payment
of such interest equalization tax, if imposed, would reduce a Fund's rate of
return on its investment. Dividends paid by foreign issuers may be subject to
withholding and other foreign taxes which may decrease the net return on such
investments as compared to dividends paid to the Fund by United States
corporations. Special rules govern the federal income tax treatment of certain
transactions denominated in terms of a currency other than the U.S. dollar or
determined by reference to the value of one or more currencies other than the
U.S. dollar. The types of transactions covered by the special rules generally
include the following: (i) the acquisition of, or becoming the obligor under, a
bond or other debt instrument (including, to the extent provided in Treasury
Regulations, preferred stock); (ii) the accruing of certain trade receivables
and payables; and (iii) the entering into or acquisition of any forward
contract, futures contract, option and similar financial instruments other than
any "regulated futures contract" or "nonequity option" marked to market. The
disposition of a currency other than the U.S. dollar by a U.S. taxpayer is also
treated as a transaction subject to the special currency rules. However, foreign
currency-related regulated futures contracts and nonequity options are generally
not subject to the special currency rules, if they are or would be treated as
sold for their fair market value at year-end under the marking to market rules
applicable to other futures contracts, unless an election is made to have such
currency rules apply. With respect to transactions covered by the special rules,
foreign currency gain or loss is calculated separately from any gain or loss on
the underlying transaction and is normally taxable as ordinary gain or loss. A
taxpayer may elect to treat as capital gain or loss foreign currency gain or
loss arising from certain identified forward contracts, futures contracts and
options that are capital assets in the hands of the taxpayer and which are not
part of a straddle. Certain transactions subject to the special currency rules
that are part of a "section 988 hedging transaction" (as defined in the Internal
Revenue Code of 1986, as amended (the "Code"), and the Treasury Regulations)
will be integrated and treated as a single transaction or otherwise treated
consistently for purposes of the Code. The income tax effects of integrating and
treating a transaction as a single transaction are generally to create a
synthetic debt instrument that is subject to the original discount provisions.
It is anticipated that some of the non-U.S. dollar denominated investments and
foreign currency contracts the Funds may make or enter into will be subject to
the special currency rules described above.

         Investments and opportunities for investments by foreign investors in
emerging market countries are subject to a variety of national policies and
restrictions. These restrictions may take the form of prior governmental
approval, limits on the amount or type of securities held by foreigners, limits
on the types of companies in which foreigners may invest and prohibitions on
foreign investments in issuers or industries deemed sensitive to national
interests. Additional restrictions may be imposed at any time by these or other
countries in which the Funds invest. Although these restrictions may in the
future make it undesirable to invest in emerging countries, a Fund's manager or
sub-adviser does not believe that any current registration restrictions would
affect its decision to invest in such countries.

Foreign Currency Transactions
         The foreign investments made by Delaware Strategic Income Fund present
currency considerations which pose special risks. Delaware International
Advisers Ltd., the Fund's sub-adviser ("Sub-Adviser"), uses a purchasing power
parity approach to evaluate currency risk. A purchasing power parity approach
attempts to identify the amount of goods and services that a dollar will buy in
the United States and compares that to the amount of a foreign currency required
to buy the same amount of goods and services in another country. When the dollar
buys less abroad, the foreign currency may be considered to be overvalued. When
the dollar buys more abroad, the foreign currency may be considered to be
undervalued. Eventually, currencies should trade at levels that should make it
possible for the dollar to buy the same amount of goods and services overseas as
in the United States.


                                                                              13
<PAGE>



         Delaware Strategic Income Fund may purchase or sell currencies and/or
engage in forward foreign currency transactions in order to expedite settlement
of portfolio transactions and to minimize currency value fluctuations. Forward
foreign currency contracts are traded in the interbank market conducted directly
between currency traders (usually large commercial banks) and their customers. A
forward contract generally has no deposit requirement, and no commissions are
charged at any stage for trades. Delaware Strategic Income Fund will account for
forward contracts by marking to market each day at daily exchange rates. When
the Fund enters into a forward contract to sell an amount of foreign currency
approximating the value of some or all of the Fund's assets denominated in such
foreign currency, the Fund's custodian bank or subcustodian will place cash or
liquid high grade debt securities in a separate account of the Fund in an amount
not less than the value of the Fund's total assets committed to the consummation
of such forward contract. If the additional cash or securities placed in the
separate account declines, additional cash or securities will be placed in the
account on a daily basis so that the value of the account will equal the amount
of Delaware Strategic Income Fund's commitments with respect to such contract.

         Delaware Strategic Income Fund's use of forward foreign currency
exchange contracts for hedging and other non-speculative purposes involves
certain risks. For example, a lack of correlation between price changes of a
forward contract and the assets being hedged could render Delaware Strategic
Income Fund's hedging strategy unsuccessful and could result in losses. The same
results could occur if movements of foreign currencies do not correlate as
expected by the Sub-Adviser at a time when the Fund is using a hedging
instrument denominated in one foreign currency to protect the value of a
security denominated in a second foreign currency against changes caused by
fluctuations in the exchange rate for the dollar and the second currency. If the
direction of securities prices, interest rates or foreign currency prices is
incorrectly predicted, Delaware Strategic Income Fund will be in a worse
position than if such transactions had not been entered into. In addition, since
there can be no assurance that a liquid secondary market will exist for any
contract purchased or sold, the Fund may be required to maintain a position
until exercise or expiration, which could result in losses. Further, forward
contracts entail particular risks related to conditions affecting the underlying
currency. Over-the-counter transactions in forward contracts also involve risks
arising from the lack of an organized exchange trading environment.

         Successful use by Delaware Strategic Income Fund of forward foreign
currency exchange contracts for hedging and other non-speculative purposes is
subject to the Sub-Adviser's ability to predict correctly the direction of
movements in foreign currencies relative to the U.S. dollar. This requires
different skills and techniques than predicting changes in the prices of
individual securities.

Equity Securities
         Each Fund may invest in income-producing equity securities. In
addition, the Delaware Delchester Fund may invest a portion of its assets in
non-income producing equity securities and the Delaware High-Yield Opportunities
Fund may make limited use of non-income producing equity securities as described
above.

         Equity securities represent ownership interests in a company and
consist of common stocks, preferred stocks, warrants to acquire common stocks
and securities convertible into common stock. Investments in equity securities
in general are subject to market risks that may cause their prices to fluctuate
over time. Fluctuations in the value of equity securities in which a Fund
invests will cause the net asset value of the Fund to fluctuate.

Convertible Debt and Non-Traditional Equity Securities
         From time to time, a portion of Delaware Corporate Bond Fund's,
Delaware Extended Duration Bond Fund's, Delaware High-Yield Opportunities Fund's
and Delaware Strategic Income Fund's assets may be invested in convertible and
debt securities of issuers in any industry. A convertible security is a security
which may be converted at a stated price within a specified period of time into
a certain quantity of the common stock of the same or a different issuer.



                                                                              14
<PAGE>

Convertible and debt securities are senior to common stocks in a corporation's
capital structure, although convertible securities are usually subordinated to
similar nonconvertible securities. Convertible and debt securities provide a
fixed-income stream and the opportunity, through its conversion feature, to
participate in the capital appreciation resulting from a market price advance in
the convertible security's underlying common stock. Just as with debt
securities, convertible securities tend to increase in market value when
interest rates decline and tend to decrease in value when interest rates rise.
However, the price of a convertible security is also influenced by the market
value of the security's underlying common stock and tends to increase as the
market value of the underlying stock rises, whereas it tends to decrease as the
market value of the underlying stock declines. Convertible and debt securities
acquired by the Fund may be rated below investment grade, or unrated. These
lower rated convertible and debt securities are subject to credit risk
considerations substantially similar to such considerations affecting high risk,
high-yield bonds, commonly referred to as "junk bonds." See High-Yield, High
Risk Securities for a further discussion of these types of investments.

         Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund,
Delaware High-Yield Opportunities Fund and Delaware Strategic Income Fund may
invest in convertible preferred stocks that offer enhanced yield features, such
as Preferred Equity Redemption Cumulative Stock ("PERCS"), which provide an
investor, such as the Fund, with the opportunity to earn higher dividend income
than is available on a company's common stock. A PERCS is a preferred stock
which generally features a mandatory conversion date, as well as a capital
appreciation limit which is usually expressed in terms of a stated price. Upon
the conversion date, most PERCS convert into common stock of the issuer (PERCS
are generally not convertible into cash at maturity). Under a typical
arrangement, if after a predetermined number of years the issuer's common stock
is trading at a price below that set by the capital appreciation limit, each
PERCS would convert to one share of common stock. If, however, the issuer's
common stock is trading at a price above that set by the capital appreciation
limit, the holder of the PERCS would receive less than one full share of common
stock. The amount of that fractional share of common stock received by the PERCS
holder is determined by dividing the price set by the capital appreciation limit
of the PERCS by the market price of the issuer's common stock. PERCS can be
called at any time prior to maturity, and hence do not provide call protection.
However, if called early, the issuer may pay a call premium over the market
price to the investor. This call premium declines at a preset rate daily, up to
the maturity date of the PERCS.

         Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund,
Delaware High-Yield Opportunities Fund and Delaware Strategic Income Fund may
also invest in other enhanced convertible securities. These include but are not
limited to ACES (Automatically Convertible Equity Securities), PEPS
(Participating Equity Preferred Stock), PRIDES (Preferred Redeemable Increased
Dividend Equity Securities), SAILS (Stock Appreciation Income Linked
Securities), TECONS (Term Convertible Notes), QICS (Quarterly Income Cumulative
Securities) and DECS (Dividend Enhanced Convertible Securities). ACES, PEPS,
PRIDES, SAILS, TECONS, QICS, and DECS all have the following features: they are
company-issued convertible preferred stock; unlike PERCS, they do not have
capital appreciation limits; they seek to provide the investor with high current
income, with some prospect of future capital appreciation; they are typically
issued with three to four-year maturities; they typically have some built-in
call protection for the first two to three years; investors have the right to
convert them into shares of common stock at a preset conversion ratio or hold
them until maturity; and upon maturity, they will automatically convert to
either cash or a specified number of shares of common stock.

When-Issued and Delayed Delivery Securities
         Each Fund may purchase securities on a when-issued or delayed delivery
basis. In such transactions, instruments are purchased with payment and delivery
taking place in the future in order to secure what is considered to be an
advantageous yield or price at the time of the transaction. Delivery of and
payment for these securities may take as long as a month or more after the date
of the purchase commitment. The Fund will maintain with its Custodian Bank a


                                                                              15
<PAGE>

separate account with a segregated portfolio of securities in an amount at least
equal to these commitments. The payment obligation and the interest rates that
will be received are each fixed at the time the Fund enters into the commitment
and no interest accrues to the Fund until settlement. Thus, it is possible that
the market value at the time of settlement could be higher or lower than the
purchase price if the general level of interest rates has changed.

Borrowing From Banks
         Each Fund may borrow money as a temporary measure for extraordinary
purposes or to facilitate redemptions. A Fund will not borrow money in excess of
one-third of the value of its net assets. A Fund has no intention of increasing
its net income through borrowing. Any borrowing will be done from a bank and, to
the extent that such borrowing exceeds 5% of the value of a Fund's net assets,
asset coverage of at least 300% is required. In the event that such asset
coverage shall at any time fall below 300%, a Fund shall, within three days
thereafter (not including Sundays or holidays, or such longer period as the SEC
may prescribe by rules and regulations), reduce the amount of its borrowings to
such an extent that the asset coverage of such borrowings shall be at least
300%. A Fund will not pledge more than 10% of its net assets, or issue senior
securities as defined in the 1940 Act, except for notes to banks. Investment
securities will not be purchased while a Fund has an outstanding borrowing.

Restricted/Illiquid Securities
         The Funds may purchase privately-placed debt and other securities whose
resale is restricted under applicable securities laws. Such restricted
securities generally offer a higher return than comparable registered securities
but involve some additional risk since they can be resold only in
privately-negotiated transactions or after registration under applicable
securities laws. The registration process may involve delays which could result
in the Funds obtaining a less favorable price on a resale. Each Fund will not
purchase illiquid assets if more than 15% of its respective net assets (10% for
Delaware Delchester Fund) would then consist of such illiquid securities.

         Illiquid securities, for purposes of this policy, include repurchase
agreements maturing in more than seven days.

         Each Fund may invest in restricted securities, including securities
eligible for resale without registration pursuant to Rule 144A ("Rule 144A
Securities") under the 1933 Act. Rule 144A exempts many privately placed and
legally restricted securities from the registration requirements of the 1933 Act
and permits such securities to be freely traded among certain institutional
buyers such as the Funds.

         While maintaining oversight, the Board of Trustees has delegated to the
Manager the day-to-day functions of determining whether or not individual Rule
144A Securities are liquid for purposes of a Fund's limitation on investments in
illiquid assets. The Board has instructed the Manager to consider the following
factors in determining the liquidity of a Rule 144A Security: (i) the frequency
of trades and trading volume for the security; (ii) whether at least three
dealers are willing to purchase or sell the security and the number of potential
purchasers; (iii) whether at least two dealers are making a market in the
security; and (iv) the nature of the security and the nature of the marketplace
trades (e.g., the time needed to dispose of the security, the method of
soliciting offers, and the mechanics of transfer).

         If the Manager determines that a Rule 144A Security which was
previously determined to be liquid is no longer liquid and, as a result, a
Fund's holdings of illiquid securities exceed the Fund's limit on investment in
such securities, the Manager will determine what action shall be taken to ensure
that the Fund continues to adhere to such limitation.

                                                                              16
<PAGE>


Repurchase Agreements
         The Funds are permitted to invest in repurchase agreements, but they
normally so only to invest cash balances. A repurchase agreement is a short-term
investment by which the purchaser acquires ownership of a debt security and the
seller agrees to repurchase the obligation at a future time and set price,
thereby determining the yield during the purchaser's holding period. Should an
issuer of a repurchase agreement fail to repurchase the underlying security, the
loss to a Fund, if any, would be the difference between the repurchase price and
the market value of the security. Each Fund will limit its investments in
repurchase agreements to those which the Manager, under the guidelines of the
Board of Trustees, determines present minimal credit risks and which are of high
quality. In addition, each Fund must have collateral of 102% of the repurchase
price, including the portion representing the Fund's yield under such
agreements, which is monitored on a daily basis.

         The funds in the Delaware Investments family have obtained an exemption
from the joint-transaction prohibitions of Section 17(d) of the 1940 Act to
allow the funds jointly to invest cash balances. The Funds may invest cash
balances in a joint repurchase agreement in accordance with the terms of the
Order and subject generally to the conditions described above.

Portfolio Loan Transactions
         Each Fund may loan up to 25% of its assets to qualified broker/dealers
or institutional investors for their use relating to short sales or other
security transactions.

         It is the understanding of the Manager that the staff of the SEC
permits portfolio lending by registered investment companies if certain
conditions are met. These conditions are as follows: 1) each transaction must
have 100% collateral in the form of cash, short-term U.S. government securities,
or irrevocable letters of credit payable by banks acceptable to the Fund
involved from the borrower; 2) this collateral must be valued daily and should
the market value of the loaned securities increase, the borrower must furnish
additional collateral to the Fund; 3) the Fund must be able to terminate any
loan after notice, at any time; 4) the Fund must receive reasonable interest on
any loan, and any dividends, interest or other distributions on the lent
securities, and any increase in the market value of such securities; 5) the Fund
may pay reasonable custodian fees in connection with the loan; 6) the voting
rights on the lent securities may pass to the borrower; however, if the Trustees
of Income Funds know that a material event will occur affecting an investment
loan, they must either terminate the loan in order to vote the proxy or enter
into an alternative arrangement with the borrower to enable the Trustees to vote
the proxy.

         The major risk to which a Fund would be exposed on a loan transaction
is the risk that the borrower would go bankrupt at a time when the value of the
security goes up. Therefore, each Fund will only enter into loan arrangements
after a review of all pertinent facts by the Manager, under the supervision of
the Board of Trustees, including the creditworthiness of the borrowing broker,
dealer or institution and then only if the consideration to be received from
such loans would justify the risk. Creditworthiness will be monitored on an
ongoing basis by the Manager.

Interest Rate and Index Swaps
         Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund and
Delaware Strategic Income Fund may invest in interest rate and index swaps to
the extent consistent with their respective investment objectives and
strategies. A Fund will only invest in swaps in which all the reference rates
are related to or derived from instruments or markets in which the Fund is
otherwise eligible to invest, and subject to the investment limitations on the
instruments to which the purchased reference rate relates.

         Swaps are agreements to exchange payment streams over a period of time
with another party, called a counterparty. Each payment stream is based on a
specified rate, which could be a fixed or variable interest rate, the rate of
return on an index, or some other reference rate. The payment streams are
calculated with reference to a hypothetical principal amount, called the

                                                                              17
<PAGE>

notional principal or the notional amount. For example, in an interest rate swap
one party may agree to pay a fixed interest rate to a counterparty and to
receive in return variable interest rate payments from the counterparty. The
amount that each party pays is calculated by multiplying the fixed and variable
rates, respectively, by the notional amount. The payment streams may thus be
thought of as interest payments on the notional amount. The notional amount does
not actually change hands at any point in the swap transaction; it is used only
to calculate the value of the payment streams.

         When two counterparties each wish to swap interest rate payments, they
typically each enter into a separate interest rate swap contract with a
broker/dealer intermediary, who is the counterparty in both transactions, rather
than entering into a swap contract with each other directly. The broker/dealer
intermediary enters into numerous transactions of this sort, and attempts to
mange its portfolio of swaps so as to match and offset its payment receipts and
obligations.

         The typical minimum notional amount is $5 million. Variable interest
rates are usually set by reference to the London Inter-Bank Offered Rate
(LIBOR). The typical maximum term of an interest rate swap agreement ranges from
one to twelve years. Index swaps tend to be shorter term, often for one year.
The Manager presently intends to purchase swaps with maturities of six to twelve
months, and in no event greater than two years.

         The Funds may also engage in index swaps, also called total return
swaps. In an index swap, a Fund may enter into a contract with a counterparty in
which the counterparty will make payments to the Fund based on the positive
returns of an index, such as a corporate bond index, in return for the Fund
paying to the counterparty a fixed or variable interest rate, as well as paying
to the counterparty any negative returns on the index. In a sense, the Fund is
purchasing exposure to an index in the amount of the notional principal in
return for making interest rate payments on the notional principal. As with
interest rate swaps, the notional principal does not actually change hands at
any point in the transaction. The counterparty, typically an investment bank,
manages its obligations to make total return payments by maintaining an
inventory of the fixed income securities that are included in the index.

          Swap transactions provide several benefits to the Funds. Interest rate
swaps may be used as a duration management tool. Duration is a measure of a
bond's interest-rate sensitivity, expressed in terms of years because it is
related to the length of time remaining on the life of a bond. In general, the
longer a bond's duration, the more sensitive the bond's price will be to changes
in interest rates. The average duration of a fund is the weighted average of the
durations of the fund's fixed income securities.

         If a Fund wished to shorten the duration of certain of its assets,
longer term assets could be sold and shorter term assets acquired, but these
transactions have potential tax and return differential consequences. By using
an interest rate swap, the Fund could agree to make semi-annual fixed rate
payments and receive semi-annual floating rate LIBOR payments adjusted every six
months. The duration of the floating rate payments received by the Fund will now
be six months. In effect, the Fund has reduced the duration of the notional
amount invested from a longer term to six months over the life of the swap
agreement.

         The Funds may also use swaps to gain exposure to specific markets. For
example, suppose bond dealers have particularly low inventories of corporate
bonds, making it difficult for a fixed-income fund to increase its exposure to
the corporate bond segment of the market. It is generally not possible to
purchase exchange-traded options on a corporate bond index. A Fund could
replicate exposure to the corporate bond market, however, by engaging in an
index swap in which the Fund gains exposure to a corporate bond index in return
for paying a LIBOR-based floating interest rate.


                                                                              19

<PAGE>

         Other uses of swaps could help permit the Funds to preserve a return or
spread on a particular investment or portion of its portfolio or to protect
against an increase in the price of securities a Fund anticipates purchasing at
a later date. Interest rate swaps may also be considered as a substitute for
interest rate futures in many cases where the hedging horizon is longer than the
maturity of the typical futures contract, and may be considered to provide more
liquidity than similar forward contracts, particularly long-term forward
contracts.

         The primary risk of swap transactions is the creditworthiness of the
counterparty, since the integrity of the transaction depends on the willingness
and ability of the counterparty to maintain the agreed upon payment stream. This
risk is often referred to as counterparty risk. If there is a default by a
counterparty in a swap transaction, the Fund's potential loss is the net amount
of payments the Fund is contractually entitled to receive for one payment period
(if any - the Fund could be in a net payment position), not the entire notional
amount, which does not change hands in a swap transaction. Swaps do not involve
the delivery of securities or other underlying assets or principal as collateral
for the transaction. A Fund will have contractual remedies pursuant to the swap
agreement but, as with any contractual remedy, there is no guarantee that a Fund
would be successful in pursuing them -- the counterparty may be judgement proof
due to insolvency, for example. The Funds thus assume the risk that they will be
delayed or prevented from obtaining payments owed to them. The standard industry
swap agreements do, however, permit a Fund to terminate a swap agreement (and
thus avoid making additional payments) in the event that a counterparty fails to
make a timely payment to the Fund.

         In response to this counterparty risk, several securities firms have
established separately capitalized subsidiaries that have a higher credit
rating, permitting them to enter into swap transactions as a dealer. The Funds
will not be permitted to enter into any swap transaction unless, at the time of
entering into such transaction, the unsecured long-term debt of the actual
counterparty, combined with any credit enhancements, is rated at least A by S&P
or Moody's or is determined to be of equivalent credit quality by the Manager.
In addition, the Manager will closely monitor the ongoing creditworthiness of
swap counterparties in order to minimize the risk of swaps.

         In addition to counterparty risk, the use of swaps also involves risks
similar to those associated with ordinary portfolio security transactions. If
the portfolio manager is incorrect in his or her forecast of market values or
interest rates, the investment performance of a Fund which has entered into a
swap transaction could be less favorable than it would have been if this
investment technique were not used. It is important to note, however, that there
is no upper limit on the amount a Fund might theoretically be required to pay in
a swap transaction.

         In order to ensure that a Fund will only engage in swap transactions to
the extent consistent with its investment objectives and strategies, a Fund will
only engage in a swap transaction if all of the reference rates used in the swap
are related to or derived from securities, instruments or markets that are
otherwise eligible investments for the Fund. Similarly, the extent to which a
Fund may invest in a swap, as measured by the notional amount, will be subject
to the same limitations as the eligible investments to which the purchased
reference rate relates.

         The Funds will, consistent with industry practice, segregate and
mark-to-market daily cash or other liquid assets having an aggregate market
value at least equal to the net amount of the excess, if any, of the Fund's
payment obligations over its entitled payments with respect to each swap
contract. To the extent that a Fund is obligated by a swap to pay a fixed or
variable interest rate, the Fund may segregate securities that are expected to
generate income sufficient to meet the Fund's net payment obligations.

         There is not a well developed secondary market for interest rate or
index swaps. Most interest rate swaps are nonetheless relatively liquid because
they can be sold back to the counterparty/dealer relatively quickly at a

                                                                              20
<PAGE>

determinable price. Most index swaps, on the other hand, are considered to be
illiquid because the counterparty/dealer will typically not unwind an index swap
prior to its termination (and, not surprisingly, index swaps tend to have much
shorter terms). The Funds will therefore treat all swaps as subject to their
limitation on illiquid investments. For purposes of calculating these percentage
limitations, the Funds will refer to the notional amount of the swap.

         Swaps will be priced using fair value pricing. The income provided by a
swap should be qualifying income for purposes of Subchapter M of the Internal
Revenue Code. Swaps should not otherwise result in any significant
diversification or valuation issues under Subchapter M.

Options, Futures and Options on Futures

         Delaware Strategic Income Fund may purchase call options or purchase
put options and will not engage in option strategies for speculative purposes.
Delaware Strategic Income Fund may invest in options that are either listed on
U.S. or recognized foreign exchanges or traded over-the-counter. Certain
over-the-counter options may be illiquid. Thus, it may not be possible to close
options positions and this may have an adverse impact on the Fund's ability to
effectively hedge its securities. Delaware Strategic Income Fund will not,
however, invest more than 15% of the value of its net assets in illiquid
securities.

         Purchasing Call Options--Delaware Strategic Income Fund may purchase
call options to the extent that premiums paid by the Fund do not aggregate more
than 2% of the Fund's total assets. When the Fund purchases a call option, in
return for a premium paid by the Fund to the writer of the option, the Fund
obtains the right to buy the security underlying the option at a specified
exercise price at any time during the term of the option. The writer of the call
option, who receives the premium upon writing the option, has the obligation,
upon exercise of the option, to deliver the underlying security against payment
of the exercise price. The advantage of purchasing call options is that Delaware
Strategic Income Fund may alter portfolio characteristics and modify portfolio
maturities without incurring the cost associated with portfolio transactions.

         Delaware Strategic Income Fund may, following the purchase of a call
option, liquidate its position by effecting a closing sale transaction. This is
accomplished by selling an option of the same series as the option previously
purchased. Delaware Strategic Income Fund will realize a profit from a closing
sale transaction if the price received on the transaction is more than the
premium paid to purchase the original call option; the Fund will realize a loss
from a closing sale transaction if the price received on the transaction is less
than the premium paid to purchase the original call option.

         Although Delaware Strategic Income Fund will generally purchase only
those call options for which there appears to be an active secondary market,
there is no assurance that a liquid secondary market on an exchange will exist
for any particular option, or at any particular time, and for some options no
secondary market on an exchange may exist. In such event, it may not be possible
to effect closing transactions in particular options, with the result that the
Fund would have to exercise its options in order to realize any profit and would
incur brokerage commissions upon the exercise of such options and upon the
subsequent disposition of the underlying securities acquired through the
exercise of such options. Further, unless the price of the underlying security
changes sufficiently, a call option purchased by Delaware Strategic Income Fund
may expire without any value to the Fund.

         Purchasing Put Options--Delaware Strategic Income Fund may invest up to
2% of its total assets in the purchase of put options. Delaware Strategic Income
Fund will, at all times during which it holds a put option, own the security
covered by such option.

         A put option purchased by Delaware Strategic Income Fund gives it the
right to sell one of its securities for an agreed price up to an agreed date.
The Fund intends to purchase put options in order to protect against a decline

                                                                              21
<PAGE>

in the market value of the underlying security below the exercise price less the
premium paid for the option ("protective puts"). The ability to purchase put
options will allow Delaware Strategic Income Fund to protect unrealized gain in
an appreciated security in its portfolio without actually selling the security.
If the security does not drop in value, Delaware Strategic Income Fund will lose
the value of the premium paid. The Fund may sell a put option which it has
previously purchased prior to the sale of the securities underlying such option.
Such sale will result in a net gain or loss depending on whether the amount
received on the sale is more or less than the premium and other transaction
costs paid on the put option which is sold.

         Delaware Strategic Income Fund may sell a put option purchased on
individual portfolio securities. Additionally, the Fund may enter into closing
sale transactions. A closing sale transaction is one in which the Fund, when it
is the holder of an outstanding option, liquidates its position by selling an
option of the same series as the option previously purchased.

         Futures and Options on Futures--Delaware Strategic Income Fund may
enter into contract for the purchase or sale for future delivery of securities
or foreign currencies. When the Fund engages in futures transactions, to the
extent required by the SEC, it will maintain with its custodian bank, assets in
a segregated account to cover its obligations with respect to such contracts,
which assets will consist of cash, cash equivalents or high quality debt
securities from its portfolio in an amount equal to the difference between the
fluctuating market value of such futures contracts and the aggregate value of
the margin payments made by the Fund with respect to such futures contracts.

         The Fund may enter into such futures contracts to protect against the
adverse affects of fluctuations in interest or foreign exchange rates without
actually buying or selling the securities or foreign currency. For example, if
interest rates are expected to increase, the Fund might enter into futures
contracts for the sale of debt securities. Such a sale would have much the same
effect as selling an equivalent value of the debt securities owned by the Fund.
If interest rates did increase, the value of the debt securities in the
portfolio would decline, but the value of the futures contracts to the Fund
would increase at approximately the same rate, thereby keeping the net asset
value of the Fund from declining as much as it otherwise would have. Similarly,
when it is expected that interest rates may decline, futures contracts may be
purchased to hedge in anticipation of subsequent purchases of securities at
higher prices. Since the fluctuations in the value of futures contracts should
be similar to those of debt securities, the Fund could take advantage of the
anticipated rise in value of debt securities without actually buying them until
the market had stabilized. At that time, the futures contracts could be
liquidated and the Fund could then buy debt securities on the cash market.

         With respect to options on futures contracts, when Delaware Strategic
Income Fund is not fully invested, it may purchase a call option on a futures
contract to hedge against a market advance due to declining interest rates. The
writing of a call option on a futures contract constitutes a partial hedge
against declining prices of the U.S. government securities which are deliverable
upon exercise of the futures contract. If the futures price at the expiration of
the option is below the exercise price, Delaware Strategic Income Fund will
retain the full amount of the option premium which provides a partial hedge
against any decline that may have occurred in the portfolio holdings. The
writing of a put option on a futures contract constitutes a partial hedge
against increasing prices of the securities which are deliverable upon exercise
of the futures contract. If the futures price at expiration of the option is
higher than the exercise price, Delaware Strategic Income Fund will retain the
full amount of the option premium which provides a partial hedge against any
increase in the price of U.S. government securities which Delaware Strategic
Income Fund intends to purchase.

         If a put or call option that Delaware Strategic Income Fund has written
is exercised, the Fund will incur a loss which will be reduced by the amount of
the premium it receives. Depending on the degree of correlation between the
value of its portfolio securities and changes in the value of its futures

                                                                              22
<PAGE>

positions, Delaware Strategic Income Fund's losses from existing options on
futures may, to some extent, be reduced or increased by changes in the value of
portfolio securities. Delaware Strategic Income Fund will purchase a put option
on futures contracts to hedge the Fund's portfolio against the risk of rising
interest rates.

         To the extent that interest rates move in an unexpected direction,
Delaware Strategic Income Fund may not achieve the anticipated benefits of
futures contracts or options on futures contracts or may realize a loss. For
example, if Delaware Strategic Income Fund hedged against the possibility of an
increase in interest rates which would adversely affect the price of U.S.
government securities held in its portfolio and interest rates decrease instead,
Delaware Strategic Income Fund will lose part or all of the benefit of the
increased value of its U.S. government securities which it has because it will
have offsetting losses in its futures position. In addition, in such situations,
if the Fund had insufficient cash, it may be required to sell U.S. government
securities from its portfolio to meet daily variation margin requirements. Such
sales of securities may, but will not necessarily, be at increased prices which
reflect the rising market. Delaware Strategic Income Fund may be required to
sell securities at a time when it may be disadvantageous to do so.

         Further, with respect to options on futures contracts, Delaware
Strategic Income Fund may seek to close out an option position by writing or
buying an offsetting position covering the same securities or contracts and have
the same exercise price and expiration date. The ability to establish and close
out positions on options will be subject to the maintenance of a liquid
secondary market, which cannot be assured.

         Although not fundamental policy, the Fund currently intends to limit
its investments in futures contracts and options thereon to the extent that not
more than 5% of the Funds assets are required as futures contract margin
deposits and premiums on options and only to the extent that obligations under
such contracts and transactions represent not more than 20% of the Fund's
assets.

U.S. Government Securities
         U.S. Treasury securities are backed by the "full faith and credit" of
the United States. Securities issued or guaranteed by federal agencies and U.S.
government sponsored instrumentalities may or may not be backed by the full
faith and credit of the United States. In the case of securities not backed by
the full faith and credit of the United States, investors in such securities
look principally to the agency or instrumentality issuing or guaranteeing the
obligation for ultimate repayment, and may not be able to assert a claim against
the United States itself in the event the agency or instrumentality does not
meet its commitment. Agencies which are backed by the full faith and credit of
the United States include the Export-Import Bank, Farmers Home Administration,
Federal Financing Bank, the Federal Housing Administration, the Maritime
Administration, the Small Business Administration, and others. Certain agencies
and instrumentalities, such as the Government National Mortgage Association
("GNMA"), are, in effect, backed by the full faith and credit of the United
States through provisions in their charters that they may make "indefinite and
unlimited" drawings on the Treasury, if needed to service its debt. Debt from
certain other agencies and instrumentalities, including the Federal Home Loan
Bank and Federal National Mortgage Association, are not guaranteed by the United
States, but those institutions are protected by the discretionary authority for
the U.S. Treasury to purchase certain amounts of their securities to assist the
institutions in meeting their debt obligations. Finally, other agencies and
instrumentalities, such as the Farm Credit System, the Tennessee Valley
Authority and the Federal Home Loan Mortgage Corporation, are federally
chartered institutions under U.S. government supervision, but their debt
securities are backed only by the creditworthiness of those institutions, not
the U.S. government.

         An instrumentality of a U.S. government agency is a government agency
organized under Federal charter with government supervision. Instrumentalities
issuing or guaranteeing securities include, among others, Federal Home Loan
Banks, the Federal Land Banks, Central Bank for Cooperatives, Federal
Intermediate Credit Banks and the Federal National Mortgage Association.

                                                                              23
<PAGE>

         The maturities of such securities usually range from three months to
thirty years. While such securities are guaranteed as to principal and interest
by the U.S. government or its instrumentalities, their market values may
fluctuate and are not guaranteed, which may, along with the other securities in
a Fund's portfolio, cause a Class' daily net asset value to fluctuate.

Short-Term Investments
         The short-term investments in which the Funds may invest are:

         (1) Time deposits, certificates of deposit (including marketable
variable rate certificates of deposit) and bankers' acceptances issued by a U.S.
commercial bank. Time deposits are non-negotiable deposits maintained in a
banking institution for a specified period of time at a stated interest rate.
Time deposits maturing in more than seven days will not be purchased by the
Funds, and time deposits maturing from two business days through seven calendar
days will not exceed 15% of the total assets of a Fund. Certificates of deposit
are negotiable short-term obligations issued by commercial banks against funds
deposited in the issuing institution. Variable rate certificates of deposit are
certificates of deposit on which the interest rate is periodically adjusted
prior to their stated maturity based upon a specified market rate. A bankers'
acceptance is a time draft drawn on a commercial bank by a borrower usually in
connection with an international commercial transaction (to finance the import,
export, transfer or storage of goods).

         The Fund will not invest in any security issued by a commercial bank
unless (i) the bank has total assets of at least $1 billion or, in the case of a
bank which does not have total assets of at least $1 billion, the aggregate
investment made in any one such bank is limited to $100,000 and the principal
amount of such investment is insured in full by the Federal Deposit Insurance
Corporation, (ii) it is a member of the Federal Deposit Insurance Corporation,
and (iii) the bank or its securities have received the highest quality rating by
a nationally-recognized statistical rating organization;

         (2) Commercial paper with the highest quality rating by a
nationally-recognized statistical rating organization (e.g., A-1 by S&P or
Prime-1 by Moody's) or, if not so rated, of comparable quality as determined by
the Manager;

         (3) Short-term corporate obligations with the highest quality rating by
a nationally-recognized statistical rating organization (e.g., AAA by S&P or Aaa
by Moody's) or, if not so rated, of comparable quality as determined by the
Manager;

         (4) U.S. government securities (see U.S. Government Securities); and

         (5) Repurchase agreements collateralized by securities listed above.

Unseasoned Companies

         Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund and
Delaware High-Yield Opportunities Fund may invest in relatively new or
unseasoned companies which are in their early stages of development, or small
companies positioned in new and emerging industries where the opportunity for
rapid growth is expected to be above average. Securities of unseasoned companies
present greater risks than securities of larger, more established companies. The
companies in which a Fund may invest may have relatively small revenues, limited
product lines, and may have a small share of the market for their products or
services. Small companies may lack depth of management, they may be unable to
internally generate funds necessary for growth or potential development or to
generate such funds through external financing or favorable terms, or they may
be developing or marketing new products or services for which markets are not
yet established and may never become established. Due to these and other
factors, small companies may suffer significant losses as well as realize
substantial growth, and investments in such companies tend to be volatile and
are therefore speculative.

                                                                              24

Mortgage-Backed Securities

         Delaware Strategic Income Fund may invest in mortgage-backed
securities, including GNMA certificates. Such securities differ from other
fixed-income securities in that principal is paid back by the borrower over the
length of the loan rather than returned in a lump sum at maturity. When
prevailing interest rates rise, the value of a GNMA security may decrease as do
other debt securities. When prevailing interest rates decline, however, the
value of GNMA securities may not rise on a comparable basis with other debt
securities because of the prepayment feature of GNMA securities. Additionally,
if a GNMA certificate is purchased at a premium above its principal value
because its fixed rate of interest exceeds the prevailing level of yields, the
decline in price to par may result in a loss of the premium in the event of
prepayment. Funds received from prepayments may be reinvested at the prevailing
interest rates which may be lower than the rate of interest that had previously
been earned.

         The mortgages backing these securities include conventional 30-year
fixed rate mortgages, graduated payment mortgages and adjustable rate mortgages.
These mortgages may be supported by various types of insurance, may be backed by
GNMA certificates or other mortgage pass-throughs issued or guaranteed by the
U.S. government, its agencies or instrumentalities. However, the guarantees do
not extend to the mortgage-backed securities' value, which is likely to vary
inversely with fluctuations in interest rates. These certificates are in most
cases "pass-through" instruments, through which the holder receives a share of
all interest and principal payments from the mortgages underlying the
certificate. Because the prepayment characteristics of the underlying mortgages
vary, it is not possible to predict accurately the average life or realized
yield of a particular issue of pass-through certificates. During periods of
declining interest rates, prepayment of mortgages underlying mortgage-backed
securities can be expected to accelerate. When the mortgage obligations are
prepaid, the Fund may reinvest the prepaid amounts in securities, the yield of
which reflects interest rates prevailing at the time. Moreover, prepayments of
mortgages which underlie securities purchased at a premium could result in
capital losses.

CMOs and REMICs

         CMOs are debt securities issued by U.S. government agencies or by
financial institutions and other mortgage lenders and collateralized by a pool
of mortgages held under an indenture. CMOs are issued in a number of classes or
series with different maturities. The classes or series are retired in sequence
as the underlying mortgages are repaid. Prepayment may shorten the stated
maturity of the obligation and can result in a loss of premium, if any has been
paid. REMICs, which were authorized under the Tax Reform Act of 1986, are
private entities formed for the purpose of holding a fixed pool of mortgages
secured by an interest in real property. REMICs are similar to CMOs in that they
issue multiple classes of securities. To the extent any privately-issued CMOs or
REMICs in which the Fund may invest are considered by the Securities and
Exchange Commission to be investment companies, Delaware Strategic Income Fund
will limit its investment in such securities in a manner consistent with the
provisions of the 1940 Act.

         Certain CMOs and REMICs may have variable or floating interest rates
and others may be stripped. Stripped mortgage securities have greater market
volatility than other types of mortgage securities in which Delaware Strategic
Income Fund may invest.

         Stripped mortgage securities are usually structured with two classes
that receive different proportions of the interest and principal distributions
on a pool of mortgage assets. A common type of stripped mortgage security will
have one class receiving some of the interest and most of the principal from the
mortgage assets, while the other class will receive most of the interest and the
remainder of the principal. In the most extreme case, one class will receive all
of the interest (the "interest-only" class), while the other class will receive
all of the principal (the "principal-only" class). The yield to maturity on an
interest-only class is extremely sensitive not only to changes in prevailing
interest rates but also to the rate of principal payments (including
prepayments) on the related underlying mortgage assets, and a rapid rate of
principal payments may have a material adverse effect on the Fund's yield to

                                                                              25

maturity. If the underlying mortgage assets experience greater than anticipated
prepayments of principal, the Fund may fail to fully recoup its initial
investment in these securities even if the securities are rated in the highest
rating categories.

         Although stripped mortgage securities are purchased and sold by
institutional investors through several investment banking firms acting as
brokers or dealers, these securities were only recently developed. As a result,
established trading markets have not yet been fully developed and, accordingly,
these securities are generally illiquid and to such extent, together with any
other illiquid investments, will not exceed 15% of the Fund's net assets.

         The Fund may invest in CMOs and REMICs issued by private entities which
are not collateralized by securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, so-called non-agency
mortgage-backed securities. Investments in these securities may be made only if
the securities (i) are rated at the time of purchase in the four top rating
categories by a nationally-recognized statistical rating organization (e.g., BBB
or better by S&P or Fitch, or Baa or better by Moody's) and (ii) represent
interests in whole-loan mortgages, multi-family mortgages, commercial mortgages
and other mortgage collateral supported by a first mortgage lien on real estate.
Non-agency mortgage-backed securities are subject to the interest rate and
prepayment risks, described above, to which other CMOs and REMICs issued by
private issuers are subject. Non-agency mortgage-backed securities may also be
subject to a greater risk of loss of interest and principal because they are not
collateralized by securities issued or guaranteed by the U.S. government. In
addition, timely information concerning the loans underlying these securities
may not be as readily available and the market for these securities may be less
liquid than other CMOs and REMICs.

Asset-Backed Securities

         The asset-backed securities in which Delaware Strategic Income Fund may
invest must be rated in the four top rating categories by a nationally
recognized statistical rating organization (e.g., BBB or better by S&P and
Fitch, or Baa or better by Moody's). The receivables underlying asset-backed
securities are typically securitized in either a pass-through or a pay-through
structure. Pass-through securities provide investors with an income stream
consisting of both principal and interest payments in respect of the receivables
in the underlying pool. Pay-through asset-backed securities are debt obligations
issued usually by a special purpose entity, which are collateralized by the
various receivables and in which the payments on the underlying receivables
provide the funds to pay the debt service on the debt obligations issued. The
Fund may invest in these and other types of asset-backed securities structured
in this way that may be developed in the future.

         The rate of principal payment on asset-backed securities generally
depends upon the rate of principal payments received on the underlying assets.
Such rate of payments may be affected by economic and various other factors such
as changes in interest rates. Therefore, the yield may be difficult to predict
and actual yield to maturity may be more or less than the anticipated yield to
maturity. Due to the shorter maturity of the collateral backing such securities,
there is less of a risk of substantial prepayment than with mortgage-backed
securities. Such asset-backed securities do, however, involve certain risks not
associated with mortgage-backed securities, including the risk that security
interests cannot be adequately or in many cases, ever, established. In addition,
with respect to credit card receivables, a number of state and federal consumer
credit laws give debtors the right to set off certain amounts owed on the credit
cards, thereby reducing the outstanding balance. In the case of automobile
receivables, there is a risk that the holders may not have either a proper or
first security interest in all of the obligations backing such receivables due
to the large number of vehicles involved in a typical issuance and technical
requirements under state laws. Therefore, recoveries on repossessed collateral
may not always be available to support payments on the securities.

                                                                              26

Investment Company Securities

         Any investments that Delaware Strategic Income Fund makes in either
closed-end or open-end investment companies will be limited by the 1940 Act, and
would involve an indirect payment of a portion of the expenses, including
advisory fees, of such other investment companies. Under the 1940 Act's current
limitations, the Fund may not (1) own more than 3% of the voting stock of
another investment company; (2) invest more than 5% of the Fund's total assets
in the shares of any one investment company; nor (3) invest more than 10% of the
Fund's total assets in shares of other investment companies. If the Fund elects
to limit its investment in other investment companies to closed-end investment
companies, the 3% limitation described above is increased to 10%. These
percentage limitations also apply to the Fund's investments in unregistered
investment companies.

REITs
         REITs are pooled investment vehicles which invest primarily in
income-producing real estate or real estate related loans or interests. REITs
are generally classified as equity REITs, mortgage REITs or a combination of
equity and mortgage REITs. Equity REITs invest the majority of their assets
directly in real property and derive income primarily from the collection of
rents. Equity REITs can also realize capital gains by selling properties that
have appreciated in value. Mortgage REITs invest the majority of their assets in
real estate mortgages and derive income from the collection of interest
payments. Like investment companies such as Income Funds, REITs are not taxed on
income distributed to shareholders provided they comply with several
requirements in the Code. REITs are subject to substantial cash flow dependency,
defaults by borrowers, self-liquidation, and the risk of failing to qualify for
tax-free pass-through of income under the Code, and/or to maintain exemptions
from the 1940 Act.

Concentration
         In applying a Fund's policy on concentration; (i) utility companies
will be divided according to their services, for example, gas, gas transmission,
electric and telephone will each be considered a separate industry; (ii)
financial service companies will be classified according to the end users of
their services, for example, automobile finance, bank finance and diversified
finance will each be considered a separate industry; and (iii) asset backed
securities will be classified according to the underlying assets securing such
securities.

PERFORMANCE INFORMATION

         From time to time, each Fund may state its Classes' total return in
advertisements and other types of literature. Any statement of total return
performance data for a Class will be accompanied by information on the average
annual compounded rate of return for that Class over, as relevant, the most
recent one-, five- and ten-year, or life-of-fund periods, as applicable. Each
Fund may also advertise aggregate and average total return information for its
Classes over additional periods of time.

         In presenting performance information for Class A Shares, the Limited
CDSC, applicable only to certain redemptions of those shares, will not be
deducted from any computation of total return. See the Prospectuses and this
Part B for a description of the Limited CDSC and the limited instances in which
it applies. All references to a CDSC in this Performance Information section
will apply to Class B Shares or Class C Shares.

         The average annual total rate of return for each Class is based on a
hypothetical $1,000 investment that includes capital appreciation and
depreciation during the stated periods. The following formula will be used for
the actual computations:

                                                                              27
<PAGE>

                                 P(1 + T)n = ERV

         Where: P  =   a hypothetical initial purchase order of $1,000 from
                       which, in the case of only Class A Shares, the maximum
                       front-end sales charge is deducted;

                T  =   average annual total return;

                n  =   number of years;

              ERV  =   Redeemable value of the hypothetical $1,000 purchase at
                       the end of the period after the deduction of the
                       applicable CDSC, if any, with respect to Class B Shares
                       and Class C Shares

         Aggregate or cumulative total return is calculated in a similar manner,
except that the results are not annualized. Each calculation assumes the maximum
front-end sales charge, if any, is deducted from the initial $1,000 investment
at the time it is made with respect to Class A Shares and that all distributions
are reinvested at net asset value, and, with respect to Class B Shares and Class
C Shares, reflects the deduction of the CDSC that would be applicable upon
complete redemption of such shares. In addition, each Fund may present total
return information that does not reflect the deduction of the maximum front-end
sales charge or any applicable CDSC.

         Each Fund may also state total return performance for its Classes in
the form of an average annual return. This average annual return figure will be
computed by taking the sum of a Class' annual returns, then dividing that figure
by the number of years in the overall period indicated. The computation will
reflect the impact of the maximum front-end sales charge or CDSC, if any, paid
on the illustrated investment amount against the first year's return.

         The performance of each Class, as shown below, is the average annual
total return quotations through July 31, 2000. The average annual total return
for Class A Shares at offer reflects the maximum front-end sales charge of 4.75%
paid on the purchase of shares. The average annual total return for Class A
Shares at net asset value (NAV) does not reflect the payment of any front-end
sales charge.

         The average annual total return shown for the Delaware Delchester Fund
Institutional Class for the periods prior to the commencement of operations of
such Class is calculated by taking the performance of Class A Shares and
adjusting it to reflect the elimination of all sales charges and asset based
charges.

         The average annual total return for Class B Shares and Class C Shares
including deferred sales charge reflects the deduction of the applicable CDSC
that would have been paid if the shares were redeemed at July 31, 2000. The
average annual total return for Class B Shares and Class C Shares excluding
deferred sales charge assumes the shares were not redeemed at July 31, 2000 and
therefore does not reflect the deduction of a CDSC.

         Securities prices fluctuated during the periods covered and past
results should not be considered as representative of future performance.

                                                                              28

(1) Performance figures for periods after May 31, 1992 reflect applicable Rule
    12b-1 distribution expenses. Future performance will be affected by such
    expenses.
(2) Total return reflects voluntary expense limitations in effect for the Fund.
    Returns would be lower without the caps. See Investment Management Agreement
    and Sub-Advisory Agreement for the limitation in effect for each Fund.

         Each Fund may also quote its current yield for each Class in
advertisements and investor communications. The yield computation is determined
by dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period and annualizing
the resulting figure, according to the following formula:

                                      a--b         6
                         YIELD = 2[(-------- + 1) --- 1]
                                            Cd

         Where: a = dividends and interest earned during the period;

                b = expenses accrued for the period (net of reimbursements);

                c = the average daily number of shares outstanding during the
                    period that were entitled to receive dividends;

                d = the maximum offering price per share on the last day of the
                    period.

         The above formula will be used in calculating quotations of yield of
each Class, based on specified 30-day periods identified in advertising by the
Fund. The yields of Class A Shares, Class B Shares and Class C Shares of each
Fund as of July 31, 2000 using this formula were as follows:

                                                                              30

</TABLE>
         Yield calculations assume the maximum front-end sales charge, if any,
and does not reflect the deduction of any CDSC or Limited CDSC. The yields for
each Fund reflect the expense limitations in effect for the Fund (see Investment
Management Agreement and Sub-Advisory Agreement for expense limitations in
effect for the Funds). Actual yield may be affected by variations in sales
charges on investments.

         Past performance, such as is reflected in quoted yields, should not be
considered as a representation of the results which may be realized from an
investment in any Class of a Fund in the future.

         Investors should note that the income earned and dividends paid by a
Fund will vary with the fluctuation of interest rates and performance of the
portfolio. The net asset value of a Fund may change. Unlike money market funds,
each Fund invests in longer-term securities that fluctuate in value and do so in
a manner inversely correlated with changing interest rates. A Fund's net asset
value will tend to rise when interest rates fall. Conversely, a Fund's net asset
value will tend to fall as interest rates rise. Normally, fluctuations in
interest rates have a greater effect on the prices of longer-term bonds. The
value of the securities held in a Fund will vary from day to day and investors
should consider the volatility of a Fund's net asset value as well as its yield
before making a decision to invest.

         Total return performance of each Class will reflect the appreciation or
depreciation of principal, reinvestment of income and any capital gains
distributions paid during any indicated period, and the impact of the maximum
front-end sales charge or CDSC, if any, paid on the illustrated investment
amount, annualized. The results will not reflect any income taxes, if
applicable, payable by shareholders on the reinvested distributions included in
the calculations. As securities prices fluctuate, an illustration of past
performance should not be considered as representative of future results.

         From time to time, each Fund may also quote its Classes' actual total
return and/or yield performance, dividend results and other performance
information in advertising and other types of literature. This information may
be compared to that of other mutual funds with similar investment objectives and
to stock, bond and other relevant indices or to rankings prepared by independent
services or other financial or industry publications that monitor the
performance of mutual funds. For example, the performance of a Fund (or Class)
may be compared to data prepared by Lipper Analytical Services, Inc.,
Morningstar, Inc. or the performance of unmanaged indices compiled or maintained
by statistical research firms such as Lehman Brothers or Salomon Brothers, Inc.

         Lipper Analytical Services, Inc. maintains statistical performance
databases, as reported by a diverse universe of independently-managed mutual
funds. Morningstar, Inc. is a mutual fund rating service that rates mutual funds
on the basis of risk-adjusted performance. Rankings that compare a Fund's
performance to another fund in appropriate categories over specific time periods

                                                                              31

also may be quoted in advertising and other types of literature. The total
return performance reported for these indices will reflect the reinvestment of
all distributions on a quarterly basis and market price fluctuations. The
indices do not take into account any sales charge or other fees. A direct
investment in an unmanaged index is not possible.

         Salomon Brothers and Lehman Brothers are statistical research firms
that maintain databases of international market, bond market, corporate and
government-issued securities of various maturities. This information, as well as
unmanaged indices compiled and maintained by these firms, will be used in
preparing comparative illustrations. In addition, the performance of multiple
indices compiled and maintained by these firms may be combined to create a
blended performance result for comparative purposes. Generally, the indices
selected will be representative of the types of securities in which a Fund may
invest and the assumptions that were used in calculating the blended performance
will be described.

         Comparative information on the Consumer Price Index may also be
included in advertisements or other literature. The Consumer Price Index, as
prepared by the U.S. Bureau of Labor Statistics, is the most commonly used
measure of inflation. It indicates the cost fluctuations of a representative
group of consumer goods. It does not represent a return from an investment.

         Ibbotson Associates of Chicago, Illinois ("Ibbotson") provides
historical returns of the capital markets in the United States, including common
stocks, small capitalization stocks, long-term corporate bonds,
intermediate-term government bonds, long-term government bonds, Treasury bills,
the U.S. rate of inflation (based on the Consumer Price Index), and combinations
of various capital markets. The performance of these capital markets is based on
the returns of different indices. A Fund may use the performance of these
capital markets in order to demonstrate general risk-versus-reward investment
scenarios. Performance comparisons may also include the value of a hypothetical
investment in any of these capital markets. The risks associated with the
security types in any capital market may or may not correspond directly to those
of a Fund. Each Fund may also compare performance to that of other compilations
or indices that may be developed and made available in the future.

         A Fund may include discussions or illustrations of the potential
investment goals of a prospective investor (including materials that describe
general principles of investing, such as asset allocation, diversification, risk
tolerance, and goal setting, questionnaires designed to help create a personal
financial profile, worksheets used to project savings needs based on assumed
rates of inflation and hypothetical rates of return and action plans offering
investment alternatives), investment management techniques, policies or
investment suitability of a Fund (such as value investing, market timing, dollar
cost averaging, asset allocation, constant ratio transfer, automatic account
rebalancing, the advantages and disadvantages of investing in tax-deferred and
taxable investments or global or international investments), economic and
political conditions, the relationship between sectors of the economy and the
economy as a whole, the effects of inflation and historical performance of
various asset classes, including but not limited to, stocks, bonds and Treasury
bills.

         From time to time advertisements, sales literature, communications to
shareholders or other materials may summarize the substance of information
contained in shareholder reports (including the investment composition of a
Fund), as well as the views as to current market, economic, trade and interest
rate trends, legislative, regulatory and monetary developments, investment
strategies and related matters believed to be of relevance to a Fund. In
addition, selected indices may be used to illustrate historic performance of
selected asset classes. A Fund may also include in advertisements, sales
literature, communications to shareholders or other materials, charts, graphs or
drawings which illustrate the potential risks and rewards of investment in
various investment vehicles, including but not limited to, domestic stocks,
and/or bonds, Treasury bills and shares of that Fund. In addition,
advertisements, sales literature, communications to shareholders or other
materials may include a discussion of certain attributes or benefits to be
derived by an investment in a Fund and/or other mutual funds, shareholder
profiles and hypothetical investor scenarios, timely information on financial
management, tax planning and investment alternatives to certificates of deposit
and other financial instruments. Such sales literature, communications to

                                                                              32
<PAGE>
shareholders or other materials may include symbols, headlines or other material
which highlight or summarize the information discussed in more detail therein.

         Materials may refer to the CUSIP numbers of a Fund and may illustrate
how to find the listings of that Fund in newspapers and periodicals. Materials
may also include discussions of other Fund products and services.

         Each Fund may quote various measures of volatility and benchmark
correlation in advertising. In addition, a Fund may compare these measures to
those of other funds. Measures of volatility seek to compare the historical
share price fluctuations or total returns to those of a benchmark. Measures of
benchmark correlation indicate how valid a comparative benchmark may be.
Measures of volatility and correlation may be calculated using averages of
historical data. Each Fund may advertise its current interest rate sensitivity,
duration, weighted average maturity or similar maturity characteristics.
Advertisements and sales materials relating to a Fund may include information
regarding the background and experience of its portfolio managers.

         The following tables present examples, for purposes of illustration
only, of cumulative total return performance for each Class of the Funds through
July 31, 2000. For these purposes, the calculations reflect maximum sales
charges, if any, and assume the reinvestment of any capital gains distributions
and income dividends paid during the indicated periods. The performance does not
reflect any income taxes payable by shareholders on the reinvested distributions
included in the calculations. The performance of Class A Shares as shown below,
reflects maximum front-end sales charge paid on the purchase of shares but is
also shown without reflecting the impact on any front-end sales charge. Total
return shown for the Delaware Delchester Fund Institutional Class for the
periods prior to the commencement of operations of such Class is calculated by
taking the performance of Class A Shares and adjusting it to reflect the
elimination of all sales charges and asset based charges. The performance of
Class B Shares and Class C Shares is calculated both with the applicable CDSC
included and excluded. The net asset value of a Class fluctuates so shares, when
redeemed, may be worth more or less than the original investment, and a Class'
results should not be considered as representative of future performance.

         Because every investor's goals and risk threshold are different, the
Distributor, as distributor for the Funds and other mutual funds available from
Delaware Investments, will provide general information about investment
alternatives and scenarios that will allow investors to assess their personal
goals. This information will include general material about investing as well as
materials reinforcing various industry-accepted principles of prudent and
responsible personal financial planning. One typical way of addressing these
issues is to compare an individual's goals and the length of time the individual
has to attain these goals to his or her risk threshold. In addition, the
Distributor will provide information that discusses the Manager's overriding
investment philosophy and how that philosophy impacts the Funds', and other
Delaware Investments funds', investment disciplines employed in seeking their
objectives. The Distributor may also from time to time cite general or specific
information about the institutional clients of affiliates of the Manager,
including the number of such clients serviced by such persons.

Dollar-Cost Averaging
         For many people, deciding when to invest can be a difficult decision.
Security prices tend to move up and down over various market cycles and logic
says to invest when prices are low. However, even experts can't always pick the
highs and the lows. By using a strategy known as dollar-cost averaging, you
schedule your investments ahead of time. If you invest a set amount on a regular
basis, that money will always buy more shares when the price is low and fewer
when the price is high. You can choose to invest at any regular interval--for
example, monthly or quarterly--as long as you stick to your regular schedule.
Dollar-cost averaging looks simple and it is, but there are important things to
remember.

         Dollar-cost averaging works best over longer time periods, and it
doesn't guarantee a profit or protect against losses in declining markets. If
you need to sell your investment when prices are low, you may not realize a
profit no matter what investment strategy you utilize. That's why dollar-cost
averaging can make sense for long-term goals. Since the potential success of a
dollar-cost averaging program depends on continuous investing, even through
periods of fluctuating prices, you should consider your dollar-cost averaging
program a long-term commitment and invest an amount you can afford and probably
won't need to withdraw. You also should consider your financial ability to
continue to purchase shares during periods of high fund share prices. Delaware
Investments offers three services -- Automatic Investing Program, Direct Deposit
Program and the Wealth Builder Option -- that can help to keep your regular
investment program on track. See Investing by Electronic Fund Transfer - Direct
Deposit Purchase Plan, Automatic Investing Plan and Wealth Builder Option under
Investment Plans for a complete description of these services, including
restrictions or limitations.

                                                                              36

         The example below illustrates how dollar-cost averaging can work. In a
fluctuating market, the average cost per share over a period of time will be
lower than the average price per share for the same time period.

THE POWER OF COMPOUNDING
         When you opt to reinvest your current income for additional Fund
shares, your investment is given yet another opportunity to grow. It's called
the Power of Compounding. Each Fund may include illustrations showing the power
of compounding in advertisements and other types of literature.


TRADING PRACTICES AND BROKERAGE
         Brokers, dealers and banks are selected to execute transactions for the
purchase or sale of portfolio securities on the basis of the Manager's judgment
of their professional capability to provide the service. The primary
consideration is to have brokers, dealers or banks execute transactions at best
execution. Best execution refers to many factors, including the price paid or
received for a security, the commission charged, the promptness and reliability
of execution, the confidentiality and placement accorded the order and other
factors affecting the overall benefit obtained by the account on the
transaction. In nearly all instances, trades are made on a net basis where
securities are either bought or sold directly from or to a broker, dealer or
bank. In these instances, there is no direct commission charged, but there is a
spread (the difference between the buy and sell price) which is the equivalent
of a commission. When a commission is paid, a Fund pays reasonably competitive
brokerage commission rates based upon the professional knowledge of the
Manager's trading department as to rates paid and charged for similar
transactions throughout the securities industry. In some instances, a Fund pays
a minimal share transaction cost when the transaction presents no difficulty.

         The Manager may allocate out of all commission business generated by
all of the funds and accounts under its management, brokerage business to
brokers or dealers who provide brokerage and research services. These services
include advice, either directly or through publications or writings, as to the
value of securities, the advisability of investing in, purchasing or selling
securities, and the availability of securities or purchasers or sellers of
securities; furnishing of analyses and reports concerning issuers, securities or
industries; providing information on economic factors and trends; assisting in
determining portfolio strategy; providing computer software and hardware used in
security analyses; and providing portfolio performance evaluation and technical
market analyses. Such services are used by the Manager in connection with its
investment decision-making process with respect to one or more funds and
accounts managed by it, and may not be used, or used exclusively, with respect
to the fund or account generating the brokerage.


         As provided in the Securities Exchange Act of 1934 (the "1934 Act") and
the Funds' Investment Management Agreement, higher commissions are permitted to
be paid to broker/dealers who provide brokerage and research services than to
broker/dealers who do not provide such services, if such higher commissions are
deemed reasonable in relation to the value of the brokerage and research
services provided. Although transactions are directed to broker/dealers who
provide such brokerage and research services, a Fund believes that the
commissions paid to such broker/dealers are not, in general, higher than
commissions that would be paid to broker/dealers not providing such services and
that such commissions are reasonable in relation to the value of the brokerage
and research services provided. In some instances, services may be provided to
the Manager which constitute in some part brokerage and research services used
by the Manager in connection with its investment decision-making process and
constitute in some part services used by the



                                                                              38

Manager in connection with administrative or other functions not related to its
investment decision-making process. In such cases, the Manager will make a good
faith allocation of brokerage and research services and will pay out of its own
resources for services used by the Manager in connection with administrative or
other functions not related to its investment decision-making process. In
addition, so long as no fund is disadvantaged, portfolio transactions which
generate commissions or their equivalent are allocated to broker/dealers who
provide daily portfolio pricing services to a Fund and to other funds in the
Delaware Investments family. Subject to best price and execution, commissions
allocated to brokers providing such pricing services may or may not be generated
by the funds receiving the pricing service.

         The Manager may place a combined order for two or more accounts or
funds engaged in the purchase or sale of the same security if, in its judgment,
joint execution is in the best interest of each participant and will result in
best price and execution. Transactions involving commingled orders are allocated
in a manner deemed equitable to each account or fund. When a combined order is
executed in a series of transactions at different prices, each account
participating in the order may be allocated an average price obtained from the
executing broker. It is believed that the ability of the accounts to participate
in volume transactions will generally be beneficial to the accounts and funds.
Although it is recognized that, in some cases, the joint execution of orders
could adversely affect the price or volume of the security that a particular
account or fund may obtain, it is the opinion of the Manager and the Board of
Trustees that the advantages of combined orders outweigh the possible
disadvantages of separate transactions.

         Consistent with the Conduct Rules of the NASD Regulation, Inc. (the
"NASD"), and subject to seeking best execution, the Funds may place orders with
broker/dealers that have agreed to defray certain expenses of the funds in the
Delaware Investments family such as custodian fees, and may, at the request of
the Distributor, give consideration to sales of such funds' shares as a factor
in the selection of brokers and dealers to execute Fund portfolio transactions.

Portfolio Turnover
         Portfolio trading will be undertaken principally to accomplish a Fund's
objective in relation to anticipated movements in the general level of interest
rates. A Fund is free to dispose of portfolio securities at any time, subject to
complying with the Internal Revenue Code of 1986, as amended, (the "Code") and
the 1940 Act, when changes in circumstances or conditions make such a move
desirable in light of the investment objective. A Fund will not attempt to
achieve or be limited to a predetermined rate of portfolio turnover, such a
turnover always being incidental to transactions undertaken with a view to
achieving a Fund's investment objective. Portfolio transactions will be
undertaken only to accomplish a Fund's objectives and not for the purpose of
realizing capital gains, although capital gains may be realized on certain
portfolio transactions. For example, capital gains may be realized when a
security is sold: (1) so that, provided capital is preserved or enhanced,
another security can be purchased to obtain a higher yield; (2) to take
advantage of what the Manager believes to be a temporary disparity in the normal
yield relationship between the two securities to increase income or improve the
quality of the portfolio; (3) to purchase a security which the Manager believes
is of higher quality than its rating or current market value would indicate; or
(4) when the Manager anticipates a decline in value due to market risk or credit
risk. Each Fund anticipates that its annual portfolio turnover may exceed 100%.





         During the past two fiscal years, each Fund's portfolio turnover rates

*      Annualized.

         Each Fund's portfolio turnover rate is calculated by dividing the
lesser of purchases or sales of portfolio securities for the particular fiscal
year by the monthly average of the value of the portfolio securities owned by
the Fund during the particular fiscal year, exclusive of securities whose
maturities at the time of acquisition are one year or less.


PURCHASING SHARES

         The Distributor serves as the national distributor for each Fund's
classes of shares, and has agreed to use its best efforts to sell shares of each
Fund. See the Prospectuses for additional information on how to invest. Shares
of the Funds are offered on a continuous basis, and may be purchased through
authorized investment dealers or directly by contacting Income Funds or the
Distributor.

         The minimum initial investment generally is $1,000 for Class A Shares,
Class B Shares and Class C Shares. Subsequent purchases of such classes
generally must be at least $100. The initial and subsequent minimum investments
for Class A Shares will be waived for purchases by officers, trustees and
employees of any fund in the Delaware Investments family, the Manager or any of
the its affiliates if the purchases are made pursuant to a payroll deduction
program. Shares purchased pursuant to the Uniform Gifts to Minors Act or Uniform
Transfers to Minors Act and shares purchased in connection with an Automatic
Investing Plan are subject to a minimum initial purchase of $250 and a minimum
subsequent purchase of $25. Accounts opened under the Asset Planner service are
subject to a minimum initial investment of $2,000 per Asset Planner Strategy
selected. There are no minimum purchase requirements for the Funds'
Institutional Classes, but certain eligibility requirements must be satisfied.

         Each purchase of Class B Shares is subject to a maximum purchase
limitation of $250,000. For Class C Shares, each purchase must be in an amount
that is less than $1,000,000. See Investment Plans for purchase limitations
applicable to retirement plans. Income Funds will reject any purchase order for
more than $250,000 of Class B Shares and $1,000,000 or more of Class C Shares.
An investor may exceed these limitations by making cumulative purchases over a
period of time. An investor should keep in mind, however, that reduced front-end
sales charges apply to investments of $100,000 or more in Class A Shares, and
that Class A Shares are


                                                                              40

<PAGE>




subject to lower annual 12b-1 Plan expenses than Class B Shares and Class C
Shares and generally are not subject to a CDSC.

          Selling dealers are responsible for transmitting orders promptly.
Income Funds reserves the right to reject any order for the purchase of shares
of a Fund if in the opinion of management such rejection is in such Fund's best
interests. If a purchase is canceled because your check is returned unpaid, you
are responsible for any loss incurred. A Fund can redeem shares from your
account(s) to reimburse itself for any loss, and you may be restricted from
making future purchases in any of the funds in the Delaware Investments family.
Each Fund reserves the right to reject purchase orders paid by third-party
checks or checks that are not drawn on a domestic branch of a United States
financial institution. If a check drawn on a foreign financial institution is
accepted, you may be subject to additional bank charges for clearance and
currency conversion.

          Each Fund also reserves the right, following shareholder notification,
to charge a service fee on non-retirement accounts that, as a result of
redemption, have remained below the minimum stated account balance for a period
of three or more consecutive months. Holders of such accounts may be notified of
their insufficient account balance and advised that they have until the end of
the current calendar quarter to raise their balance to the stated minimum. If
the account has not reached the minimum balance requirement by that time, the
Fund will charge a $9 fee for that quarter and each subsequent calendar quarter
until the account is brought up to the minimum balance. The service fee will be
deducted from the account during the first week of each calendar quarter for the
previous quarter, and will be used to help defray the cost of maintaining
low-balance accounts. No fees will be charged without proper notice, and no CDSC
will apply to such assessments.

          Each Fund also reserves the right, upon 60 days' written notice, to
involuntarily redeem accounts that remain under the minimum initial purchase
amount as a result of redemptions. An investor making the minimum initial
investment may be subject to involuntary redemption without the imposition of a
CDSC or Limited CDSC if he or she redeems any portion of his or her account.

         The NASD has adopted Conduct Rules, as amended, relating to investment
company sales charges. Income Funds and the Distributor intend to operate in
compliance with these rules.

         Class A Shares are purchased at the offering price which reflects a
maximum front-end sales charge of 4.75%; however, lower front-end sales charges
apply for larger purchases. See the table in the Fund Classes' Prospectuses.
Class A Shares are also subject to annual 12b-1 Plan expenses for the life of
the investment.

         Class B Shares are subject to a CDSC of: (i) 4% if shares are redeemed
within two years of purchase; (ii) 3% if shares are redeemed during the third or
fourth year following purchase; (iii) 2% if shares are redeemed during the fifth
year following purchase; and (iv) 1% if shares are redeemed during the sixth
year following purchase. Class B Shares are subject to annual 12b-1 Plan
expenses for approximately eight years after purchase. See Automatic Conversion
of Class B Shares, below.

         Class C Shares are purchased at net asset value and are subject to a
CDSC of 1% if shares are redeemed within 12 months following purchase. Class C
Shares are also subject to annual 12b-1 Plan expenses for the life of the
investment which are equal to those to which Class B Shares are subject.

         Institutional Class shares are purchased at the net asset value per
share without the imposition of a front-end or contingent deferred sales charge
or 12b-1 Plan expenses. See Determining Offering Price and Net Asset Value and
Plans Under Rule 12b-1 for the Fund Classes in this Part B.


                                                                              41

<PAGE>


         Class A Shares, Class B Shares, Class C Shares and Institutional Class
shares represent a proportionate interest in a Fund's assets and will receive a
proportionate interest in that Fund's income, before application, as to Class A,
Class B and Class C Shares, of any expenses under that Fund's 12b-1 Plans.

         Certificates representing shares purchased are not ordinarily issued in
the case of Class A Shares or Institutional Class shares, unless a shareholder
submits a specific request. Certificates are not issued in the case of Class B
Shares or Class C Shares or in the case of any retirement plan account including
self-directed IRAs. However, purchases not involving the issuance of
certificates are confirmed to the investor and credited to the shareholder's
account on the books maintained by Delaware Service Company, Inc. (the "Transfer
Agent"). The investor will have the same rights of ownership with respect to
such shares as if certificates had been issued. An investor that is permitted to
obtain a certificate may receive a certificate representing full share
denominations purchased by sending a letter signed by each owner of the account
to the Transfer Agent requesting the certificate. No charge is assessed by
Income Funds for any certificate issued. A shareholder may be subject to fees
for replacement of a lost or stolen certificate under certain conditions,
including the cost of obtaining a bond covering the lost or stolen certificate.
Please contact the Funds for further information. Investors who hold
certificates representing any of their shares may only redeem those shares by
written request. The investor's certificate(s) must accompany such request.

Alternative Purchase Arrangements - Class A, B and C Shares
         The alternative purchase arrangements of Class A Shares, Class B Shares
and Class C Shares permit investors to choose the method of purchasing shares
that is most suitable for their needs given the amount of their purchase, the
length of time they expect to hold their shares and other relevant
circumstances. Investors should determine whether, given their particular
circumstances, it is more advantageous to purchase Class A Shares and incur a
front-end sales charge and annual 12b-1 Plan expenses of up to a maximum of
0.30% (currently no more than 0.25% in the case of Delaware Corporate Bond Fund,
Delaware Extended Duration Bond Fund and Delaware Strategic Income Fund,
pursuant to Board action) of the average daily net assets of Class A Shares, or
to purchase either Class B or Class C Shares and have the entire initial
purchase amount invested in the Fund with the investment thereafter subject to a
CDSC and annual 12b-1 Plan expenses. Class B Shares are subject to a CDSC if the
shares are redeemed within six years of purchase, and Class C Shares are subject
to a CDSC if the shares are redeemed within 12 months of purchase. Class B and
Class C Shares are each subject to annual 12b-1 Plan expenses of up to a maximum
of 1% (0.25% of which are service fees to be paid to the Distributor, dealers or
others for providing personal service and/or maintaining shareholder accounts)
of average daily net assets of the respective Class. Class B Shares will
automatically convert to Class A Shares at the end of approximately eight years
after purchase and, thereafter, be subject to annual 12b-1 Plan expenses of up
to a maximum of 0.30% of average daily net assets of such shares. Unlike Class B
Shares, Class C Shares do not convert to another Class.

         The higher 12b-1 Plan expenses on Class B Shares and Class C Shares
will be offset to the extent a return is realized on the additional money
initially invested upon the purchase of such shares. However, there can be no
assurance as to the return, if any, that will be realized on such additional
money. In addition, the effect of any return earned on such additional money
will diminish over time. In comparing Class B Shares to Class C Shares,
investors should also consider the duration of the annual 12b-1 Plan expenses to
which each of the Classes is subject and the desirability of an automatic
conversion feature, which is available only for Class B Shares.

         For the distribution and related services provided to, and the expenses
borne on behalf of, the Funds, the Distributor and others will be paid, in the
case of Class A Shares, from the proceeds of the front-end sales charge and
12b-1 Plan fees and, in the case of Class B Shares and Class C Shares, from the
proceeds of the 12b-1 Plan fees and, if applicable, the CDSC incurred upon
redemption. Financial advisers may receive different compensation for selling
Class A Shares, Class B Shares and Class C Shares. Investors should understand
that


                                                                              42

<PAGE>


the purpose and function of the respective 12b-1 Plans and the CDSCs applicable
to Class B Shares and Class C Shares are the same as those of the 12b-1 Plan and
the front-end sales charge applicable to Class A Shares in that such fees and
charges are used to finance the distribution of the respective Classes. See
Plans under Rule 12b-1 for the Fund Classes.

         Dividends, if any, paid on Class A Shares, Class B Shares, Class C
Shares and Institutional Class Shares will be calculated in the same manner, at
the same time and on the same day and will be in the same amount, except that
the amount of 12b-1 Plan expenses relating to Class B Shares and Class C Shares
will be borne exclusively by such shares. See Determining Offering Price and Net
Asset Value.

Class A Shares
         Purchases of $100,000 or more of Class A Shares at the offering price
carry reduced front-end sales charges as shown in the table in the Fund Classes'
Prospectuses, and may include a series of purchases over a 13-month period under
a Letter of Intention signed by the purchaser. See Special Purchase Features -
Class A Shares, below for more information on ways in which investors can avail
themselves of reduced front-end sales charges and other purchase features.

         From time to time, upon written notice to all of its dealers, the
Distributor may hold special promotions for specified periods during which the
Distributor may reallow to dealers up to the full amount of the front-end sales
charge. In addition, certain dealers who enter into an agreement to provide
extra training and information on Delaware Investments products and services and
who increase sales of Delaware Investments funds may receive an additional
commission of up to 0.15% of the offering price in connection with sales of
Class A Shares. Such dealers must meet certain requirements in terms of
organization and distribution capabilities and their ability to increase sales.
The Distributor should be contacted for further information on these
requirements as well as the basis and circumstances upon which the additional
commission will be paid. Participating dealers may be deemed to have additional
responsibilities under the securities laws. Dealers who receive 90% or more of
the sales charge may be deemed to be underwriters under the 1933 Act.

Dealer's Commission
         As described in the Prospectuses, for initial purchases of Class A
Shares of $1,000,000 or more, a dealer's commission may be paid by the
Distributor to financial advisers through whom such purchases are effected.

         For accounts with assets over $1 million, the dealer commission resets
annually to the highest incremental commission rate on the anniversary of the
first purchase. In determining a financial adviser's eligibility for the
dealer's commission, purchases of Class A Shares of other Delaware Investments
funds as to which a Limited CDSC applies (see Contingent Deferred Sales Charge
for Certain Redemptions of Class A Shares Purchased at Net Asset Value under
Redemption and Exchange) may be aggregated with those of the Class A Shares of a
Fund. Financial advisers also may be eligible for a dealer's commission in
connection with certain purchases made under a Letter of Intention or pursuant
to an investor's Right of Accumulation. Financial advisers should contact the
Distributor concerning the applicability and calculation of the dealer's
commission in the case of combined purchases.

         An exchange from other Delaware Investments funds will not qualify for
payment of the dealer's commission, unless a dealer's commission or similar
payment has not been previously paid on the assets being exchanged. The schedule
and program for payment of the dealer's commission are subject to change or
termination at any time by the Distributor at its discretion.


                                                                              43


<PAGE>


Contingent Deferred Sales Charge - Class B Shares and Class C Shares
         Class B Shares and Class C Shares are purchased without a front-end
sales charge. Class B Shares redeemed within six years of purchase may be
subject to a CDSC at the rates set forth above, and Class C Shares redeemed
within 12 months of purchase may be subject to a CDSC of 1%. CDSCs are charged
as a percentage of the dollar amount subject to the CDSC. The charge will be
assessed on an amount equal to the lesser of the net asset value at the time of
purchase of the shares being redeemed or the net asset value of those shares at
the time of redemption. No CDSC will be imposed on increases in net asset value
above the initial purchase price, nor will a CDSC 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 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. See Waivers of
Contingent Deferred Sales Charge-- under Redemption and Exchange for the Fund
Classes for a list of the instances in which the CDSC is waived.

         During the seventh year after purchase and, thereafter, until converted
automatically into Class A Shares, Class B Shares will still be subject to the
annual 12b-1 Plan expenses of up to 1% of average daily net assets of those
shares. At the end of approximately eight years after purchase, the investor's
Class B Shares will be automatically converted into Class A Shares of the same
Fund. See Automatic Conversion of Class B Shares below. Such conversion will
constitute a tax-free exchange for federal income tax purposes. Investors are
reminded that the Class A Shares into which Class B Shares will convert are
subject to ongoing annual 12b-1 Plan expenses of up to a maximum of 0.30%
(currently no more than 0.25% in the case of Delaware Corporate Bond Fund,
Delaware Extended Duration Bond Fund and Delaware Strategic Income Fund) of
average daily net assets of such shares.

         In determining whether a CDSC applies to a redemption of Class B
Shares, it will be assumed that shares held for more than six years are redeemed
first, followed by shares acquired through the reinvestment of dividends or
distributions, and finally by shares held longest during the six-year period.
With respect to 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.

         All investments made during a calendar month, regardless of what day of
the month the investment occurred, will age one month on the last day of that
month and each subsequent month.

Deferred Sales Charge Alternative - Class B Shares
         Class B Shares may be purchased at net asset value without a front-end
sales charge and, as a result, the full amount of the investor's purchase
payment will be invested in Fund shares. The Distributor currently compensates
dealers or brokers for selling Class B Shares at the time of purchase from its
own assets in an amount equal to no more than 4% of the dollar amount purchased.
In addition, from time to time, upon written notice to all of its dealers, the
Distributor may hold special promotions for specified periods during which the
Distributor may pay additional compensation to dealers or brokers for selling
Class B Shares at the time of purchase. As discussed below, however, Class B
Shares are subject to annual 12b-1 Plan expenses and, if redeemed within six
years of purchase, a CDSC.

         Proceeds from the CDSC and the annual 12b-1 Plan fees are paid to the
Distributor and others for providing distribution and related services, and
bearing related expenses, in connection with the sale of Class B Shares. These
payments support the compensation paid to dealers or brokers for selling Class B
Shares. Payments to the Distributor and others under the Class B 12b-1 Plan may
be in an amount equal to no more than 1% annually. The combination of the CDSC
and the proceeds of the 12b-1 Plan fees makes it possible for a Fund to sell
Class B Shares without deducting a front-end sales charge at the time of
purchase.


                                                                              44

<PAGE>


         Holders of Class B Shares who exercise the exchange privilege described
below will continue to be subject to the CDSC schedule for Class B Shares
described in this Part B, even after the exchange. Such CDSC schedule may be
higher than the CDSC schedule for Class B Shares acquired as a result of the
exchange. See Redemption and Exchange.

Automatic Conversion of Class B Shares
         Class B Shares, other than shares acquired through reinvestment of
dividends, held for eight years after purchase are eligible for automatic
conversion into Class A Shares. Conversions of Class B Shares into Class A
Shares will occur only four times in any calendar year, on the 18th day (or next
business day) of March, June, September and December (each, a "Conversion
Date"). If the eighth anniversary after a purchase of Class B Shares falls on a
Conversion Date, an investor's Class B Shares will be converted on that date. If
the eighth anniversary occurs between Conversion Dates, an investor's Class B
Shares will be converted on the next Conversion Date after such anniversary.
Consequently, if a shareholder's eighth anniversary falls on the day after a
Conversion Date, that shareholder will have to hold Class B Shares for as long
as three additional months after the eighth anniversary of purchase before the
shares will automatically convert into Class A Shares.


         Class B Shares of a fund acquired through a reinvestment of dividends
will convert to the corresponding Class A Shares of that fund (or, in the case
of Delaware Group Cash Reserve, the Delaware Cash Reserve Fund Consultant Class)
pro-rata with Class B Shares of that fund not acquired through dividend
reinvestment.


         All such automatic conversions of Class B Shares will constitute
tax-free exchanges for federal income tax purposes.  See Taxes.

Level Sales Charge Alternative - Class C Shares
         Class C Shares may be purchased at net asset value without a front-end
sales charge and, as a result, the full amount of the investor's purchase
payment will be invested in Fund shares. The Distributor currently compensates
dealers or brokers for selling Class C Shares at the time of purchase from its
own assets in an amount equal to no more than 1% of the dollar amount purchased.
As discussed below, Class C Shares are subject to annual 12b-1 Plan expenses
and, if redeemed within 12 months of purchase, a CDSC.

         Proceeds from the CDSC and the annual 12b-1 Plan fees are paid to the
Distributor and others for providing distribution and related services, and
bearing related expenses, in connection with the sale of Class C Shares. These
payments support the compensation paid to dealers or brokers for selling Class C
Shares. Payments to the Distributor and others under the Class C 12b-1 Plan may
be in an amount equal to no more than 1% annually.

         Holders of Class C Shares who exercise the exchange privilege described
below will continue to be subject to the CDSC schedule for Class C Shares as
described in this Part B. See Redemption and Exchange.

Plans Under Rule 12b-1 for the Fund Classes
         Pursuant to Rule 12b-1 under the 1940 Act, Income Funds has adopted a
separate plan for each of the Class A Shares, Class B Shares and Class C Shares
of each Fund (the "Plans"). Each Plan permits the relevant Fund to pay for
certain distribution, promotional and related expenses involved in the marketing
of only the class of shares to which the Plan applies. The Plans do not apply to
Institutional Classes of shares. Such shares are not included in calculating the
Plans' fees, and the Plans are not used to assist in the distribution and
marketing of shares of the Institutional Classes. Shareholders of the
Institutional Classes may not vote on matters affecting the Plans.

                                                                              45

<PAGE>


         The Plans permit a Fund, pursuant to its Distribution Agreement, to pay
out of the assets of Class A Shares, Class B Shares and Class C Shares monthly
fees to the Distributor for its services and expenses in distributing and
promoting sales of shares of such classes. These expenses include, among other
things, preparing and distributing advertisements, sales literature and
prospectuses and reports used for sales purposes, compensating sales and
marketing personnel, and paying distribution and maintenance fees to securities
brokers and dealers who enter into agreements with the Distributor. The Plan
expenses relating to Class B and Class C Shares are also used to pay the
Distributor for advancing the commission costs to dealers with respect to the
initial sale of such shares.

         In addition each Fund may make payments out of the assets of Class A,
Class B and Class C Shares directly to other unaffiliated parties, such as
banks, who either aid in the distribution of shares of, or provide services to,
such classes.

         The maximum aggregate fee payable by a Fund under its Plans, and the
Funds' Distribution Agreements, is on an annual basis, up to 0.30% of the Class
A Shares' average daily net assets for the year, and up to 1% (0.25% of which
are service fees to be paid to the Distributor, dealers and others for providing
personal service and/or maintaining shareholder accounts) of each of the Class B
Shares' and Class C Shares' average daily net assets for the year. Income Funds'
Board of Trustees may reduce these amounts at any time. The Distributor has
agreed to waive the distribution fees with respect to Delaware Delchester Fund
and Delaware High-Yield Opportunities Fund to the extent such fee for any day
exceeds the net investment income realized by such Funds' respective Class A,
Class B and Class C Shares for such day.

         Although the maximum fee payable under the 12b-1 Plan relating to
Delaware Delchester Fund A Class is 0.30% of average daily net assets of such
class, the Board of Trustees has determined that the annual fee, payable on a
monthly basis, under the Plan relating to Delaware Delchester Fund A Class, will
be equal to the sum of: (i) the amount obtained by multiplying 0.10% by the
average daily net assets represented by Delaware Delchester Fund A Class that
were originally purchased prior to June 1, 1992 in Delchester I class (which was
converted into what is now referred to as Class A Shares on June 1, 1992
pursuant to a Plan of Recapitalization approved by shareholders of Delchester I
class), and (ii) the amount obtained by multiplying 0.30% by the average daily
net assets represented by all other Delaware Delchester Fund A Class shares.
While this is the method to be used to calculate the 12b-1 fees to be paid by
Delaware Delchester Fund A Class under its Plan, the fee is a Class A Shares'
expense so that all shareholders of Delaware Delchester Fund A Class, regardless
of whether they originally purchased or received shares in Delchester I class,
or in one of the other classes that is now known as Class A Shares, will bear
12b-1 expenses at the same rate. In addition, pursuant to Board action, the
maximum aggregate fee payable by Class A Shares of Delaware Corporate Bond Fund,
Delaware Extended Duration Bond Fund and Delaware Strategic Income Fund is
0.25%. While this describes the current basis for calculating the fees which
will be payable under the Delaware Corporate Bond Fund A Class', Delaware
Delchester Fund A Class', Delaware Extended Duration Bond Fund A Class' and
Delaware Strategic Income Fund A Class' Plans, such Plans permit a full 0.30% on
all Class A Shares' assets to be paid at any time following appropriate Board
approval.


         All of the distribution expenses incurred by the Distributor and
others, such as broker/dealers, in excess of the amount paid on behalf of Class
A, Class B and Class C Shares would be borne by such persons without any
reimbursement from such Fund Classes. Subject to seeking best price and
execution, a Fund may, from time to time, buy or sell portfolio securities from
or to firms which receive payments under the Plans.

         From time to time, the Distributor may pay additional amounts from its
own resources to dealers for aid in distribution or for aid in providing
administrative services to shareholders.


                                                                              46

         The Plans and the Distribution Agreements, have all been approved by
the Board of Trustees of Income Funds, including a majority of the trustees who
are not "interested persons" (as defined in the 1940 Act) of Income Funds and
who have no direct or indirect financial interest in the Plans, by vote cast in
person at a meeting duly called for the purpose of voting on the Plans and such
Agreements. Continuation of the Plans and the Distribution Agreements, as
amended, must be approved annually by the Board of Trustees in the same manner
as specified above.

         Each year, the trustees must determine whether continuation of the
Plans is in the best interest of shareholders of, respectively, Class A Shares,
Class B Shares and Class C Shares of each Fund and that there is a reasonable
likelihood of the Plan relating to a Fund Class providing a benefit to that
Class. The Plans and the Distribution Agreements may be terminated with respect
to a Class at any time without penalty by a majority of those trustees who are
not "interested persons" or by a majority vote of the outstanding voting
securities of the relevant Fund Class. Any amendment materially increasing the
percentage payable under the Plans must likewise be approved by a majority vote
of the outstanding voting securities of the relevant Fund Class, as well as by a
majority vote of those trustees who are not "interested persons." With respect
to each Class A Shares' Plan, any material increase in the maximum percentage
payable thereunder must also be approved by a majority of the outstanding voting
securities of Class B of the same Fund. Also, any other material amendment to
the Plans must be approved by a majority vote of the trustees including a
majority of the noninterested trustees of Income Funds having no interest in the
Plans. In addition, in order for the Plans to remain effective, the selection
and nomination of trustees who are not "interested persons" of Income Funds must
be effected by the trustees who themselves are not "interested persons" and who
have no direct or indirect financial interest in the Plans. Persons authorized
to make payments under the Plans must provide written reports at least quarterly
to the Board of Trustees for their review.



                                                                              47

Other Payments to Dealers - Class A Shares, Class B Shares and Class C Shares
         From time to time, at the discretion of the Distributor, all registered
broker/dealers whose aggregate sales of Fund Classes exceed certain limits as
set by the Distributor, may receive from the Distributor an additional payment
of up to 0.25% of the dollar amount of such sales. The Distributor may also
provide additional promotional incentives or payments to dealers that sell
shares of the Delaware Investments family of funds. In some instances, these
incentives or payments may be offered only to certain dealers who maintain, have
sold or may sell certain amounts of shares. The Distributor may also pay a
portion of the expense of preapproved dealer advertisements promoting the sale
of Delaware Investments fund shares.

                                                                              49

Special Purchase Features - Class A Shares

Buying Class A Shares at Net Asset Value
        Class A Shares of the Fund may be purchased at net asset value under the
Delaware Investments Dividend Reinvestment Plan and, under certain
circumstances, the Exchange Privilege and the 12-Month Reinvestment Privilege.


        Current and former officers, trustees/directors and employees of Income
Funds, any other fund in the Delaware Investments family, the Manager, or any of
the Manager's current affiliates and those that may in the future be created,
legal counsel to the funds and registered representatives and employees of
broker/dealers who have entered into Dealer's Agreements with the Distributor
may purchase Class A Shares and any such class of shares of any of the other
funds in the Delaware Investments family, including any fund that may be
created, at the net asset value per share. Family members (regardless of age) of
such persons at their direction, and any employee benefit plan established by
any of the foregoing funds, corporations, counsel or broker/dealers may also
purchase Class A Shares at net asset value. Class A Shares may also be purchased
at net asset value by current and former officers, directors and employees (and
members of their families) of the Dougherty Financial Group LLC.


        Purchases of Class A Shares may also be made by clients of registered
representatives of an authorized investment dealer at net asset value within 12
months after the registered representative changes employment, if the purchase
is funded by proceeds from an investment where a front-end sales charge,
contingent deferred sales charge or other sales charge has been assessed.
Purchases of Class A Shares may also be made at net asset value by bank
employees who provide services in connection with agreements between the bank
and unaffiliated brokers or dealers concerning sales of shares of funds in the
Delaware Investments family. Officers, trustees and key employees of
institutional clients of the Manager or any of its affiliates may purchase Class
A Shares at net asset value. Moreover, purchases may be effected at net asset
value for the benefit of the clients of brokers, dealers and registered
investment advisers affiliated with a broker or dealer, if such broker, dealer
or investment adviser has entered into an agreement with the Distributor
providing specifically for the purchase of Class A Shares in connection with
special investment products, such as wrap accounts or similar fee based
programs. Investors may be charged a fee when effecting transactions in Class A
Shares through a broker or agent that offers these special investment products.

         Purchases of Class A Shares of each Fund at net asset value may also be
made by the following: financial institutions investing for the account of their
trust customers if they are not eligible to purchase shares of the Institutional
Class of a Fund; any group retirement plan (excluding defined benefit pension
plans), or such plans of the same employer, for which plan participant records
are maintained on the Retirement Financial Services, Inc. (formerly known as
Delaware Investment & Retirement Services, Inc.) proprietary record keeping
system that (i) has in excess of $500,000 of plan assets invested in Class A
Shares of funds in the Delaware Investments family and any stable value account
available to investment advisory clients of the Manager or its affiliates; or
(ii) is sponsored by an employer that has at any point after May 1, 1997 had
more than 100 employees while such plan has held Class A Shares of a fund in the
Delaware Investments family and such employer has properly represented in
writing to Retirement Financial Services, Inc. that it has the requisite number
of employees and received written confirmation back from Retirement Financial
Services, Inc. See Group Investment Plans for information regarding the
applicability of the Limited CDSC.

                                                                              50

<PAGE>



       Purchases of Class A Shares at net asset value may also be made by any
group retirement plan (excluding defined benefit pension plans) that purchases
shares through a retirement plan alliance program that requires shares to be
available at net asset value, provided Retirement Financial Services, Inc.
either is the sponsor of the alliance program or has a product participation
agreement with the sponsor of the alliance program.

         Purchases of Class A Shares at net asset value may also be made by bank
sponsored retirement plans that are no longer eligible to purchase Institutional
Class Shares or purchase interests in a collective trust as a result of a change
in distribution arrangements.

         Investments in Class A Shares made by plan level and/or participant
retirement accounts that are for the purpose of repaying a loan taken from such
accounts will be made at net asset value. Loan repayments made to a fund account
in connection with loans originated from accounts previously maintained by
another investment firm will also be invested at net asset value.

         Income Funds must be notified in advance that the trade qualifies for
purchase at net asset value.

Allied Plans
        Class A Shares are available for purchase by participants in certain
401(k) Defined Contribution Plans ("Allied Plans") which are made available
under a joint venture agreement between the Distributor and another institution
through which mutual funds are marketed and which allow investments in Class A
Shares of designated Delaware Investments funds ("eligible Delaware Investments
fund shares"), as well as shares of designated classes of non-Delaware
Investments funds ("eligible non-Delaware Investments fund shares"). Class B
Shares and Class C Shares are not eligible for purchase by Allied Plans.

        With respect to purchases made in connection with an Allied Plan, the
value of eligible Delaware Investments and eligible non-Delaware Investments
fund shares held by the Allied Plan may be combined with the dollar amount of
new purchases by that Allied Plan to obtain a reduced front-end sales charge on
additional purchases of eligible Delaware Investments fund shares. See Combined
Purchases Privilege, below.

        Participants in Allied Plans may exchange all or part of their eligible
Delaware Investments fund shares for other eligible Delaware Investments fund
shares or for eligible non-Delaware Investments fund shares at net asset value
without payment of a front-end sales charge. However, exchanges of eligible fund
shares, both Delaware Investments and non-Delaware Investments, which were not
subject to a front end sales charge, will be subject to the applicable sales
charge if exchanged for eligible Delaware Investments fund shares to which a
sales charge applies. No sales charge will apply if the eligible fund shares
were previously acquired through the exchange of eligible shares on which a
sales charge was already paid or through the reinvestment of dividends. See
Investing by Exchange under Investment Plans.

        A dealer's commission may be payable on purchases of eligible Delaware
Investments fund shares under an Allied Plan. In determining a financial
adviser's eligibility for a dealer's commission on net asset value purchases of
eligible Delaware Investments fund shares in connection with Allied Plans, all
participant holdings in the Allied Plan will be aggregated. See Class A Shares,
above.

        The Limited CDSC is applicable to redemptions of net asset value
purchases from an Allied Plan on which a dealer's commission has been paid.
Waivers of the Limited CDSC, as described under Waiver of Limited Contingent
Deferred Sales Charge - Class A Shares under Redemption and Exchange, apply to
redemptions by participants in Allied Plans except in the case of exchanges
between eligible Delaware Investments and non-Delaware Investments fund shares.
When eligible Delaware Investments fund shares are exchanged into eligible
non-Delaware Investments fund shares, the Limited CDSC will be imposed at the
time of the exchange, unless the joint venture agreement specifies that the
amount of the Limited CDSC will be paid

                                                                              51

<PAGE>


by the financial adviser or selling dealer. See Contingent Deferred Sales Charge
for Certain Redemptions of Class A Shares Purchased at Net Asset Value under
Redemption and Exchange.


Letter of Intention
         The reduced front-end sales charges described above with respect to
Class A Shares are also applicable to the aggregate amount of purchases made by
any such purchaser previously enumerated within a 13-month period pursuant to a
written Letter of Intention provided by the Distributor and signed by the
purchaser, and not legally binding on the signer or Income Funds which provides
for the holding in escrow by the Transfer Agent, of 5% of the total amount of
Class A Shares intended to be purchased until such purchase is completed within
the 13-month period. A Letter of Intention may be dated to include shares
purchased up to 90 days prior to the date the Letter is signed. The 13-month
period begins on the date of the earliest purchase. If the intended investment
is not completed, except as noted below, the purchaser will be asked to pay an
amount equal to the difference between the front-end sales charge on Class A
Shares purchased at the reduced rate and the front-end sales charge otherwise
applicable to the total shares purchased. If such payment is not made within 20
days following the expiration of the 13-month period, the Transfer Agent will
surrender an appropriate number of the escrowed shares for redemption in order
to realize the difference. Those purchasers may include the value (at offering
price at the level designated in their Letter of Intention) of all Classes of
shares of a Fund and of the other mutual funds in Delaware Investments
previously purchased and still held as of the date of their Letter of Intention
toward the completion of such Letter, except as described below. Those
purchasers cannot include shares that did not carry a front-end sales charge,
CDSC or Limited CDSC, unless the purchaser acquired those shares through an
exchange from a Delaware Investments fund that did carry a front-end sales
charge, CDSC or Limited CDSC.


         Employers offering a Delaware Investments retirement plan may also
complete a Letter of Intention to obtain a reduced front-end sales charge on
investments of Class A Shares made by the plan. The aggregate investment level
of the Letter of Intention will be determined and accepted by the Transfer Agent
at the point of plan establishment. The level and any reduction in front-end
sales charge will be based on actual plan participation and the projected
investments in Delaware Investments funds that are offered with a front-end
sales charge, CDSC or Limited CDSC for a 13-month period. The Transfer Agent
reserves the right to adjust the signed Letter of Intention based on this
acceptance criteria. The 13-month period will begin on the date this Letter of
Intention is accepted by the Transfer Agent. If actual investments exceed the
anticipated level and equal an amount that would qualify the plan for further
discounts, any front-end sales charges will be automatically adjusted. In the
event this Letter of Intention is not fulfilled within the 13-month period, the
plan level will be adjusted (without completing another Letter of Intention) and
the employer will be billed for the difference in front-end sales charges due,
based on the plan's assets under management at that time. Employers may also
include the value (at offering price at the level designated in their Letter of
Intention) of all their shares intended for purchase that are offered with a
front-end sales charge, CDSC or Limited CDSC of any class. Class B Shares and
Class C Shares of a Fund and other funds in the Delaware Investments family
which offer corresponding classes of shares may also be aggregated for this
purpose.


Combined Purchases Privilege
         When you determine the availability of the reduced front-end sales
charges on Class A Shares, you can include, subject to the exceptions described
below, the total amount of any


                                                                              52

<PAGE>



Class of shares you own of a Fund and all other Delaware Investments mutual
funds. In addition, if you are an investment advisory client of the Manager's
affiliates you may include assets held in a stable value account in the total
amount. However, you cannot include mutual fund shares that do not carry a
front-end sales charge, CDSC or Limited CDSC, unless you acquired those shares
through an exchange from a Delaware Investments mutual fund that did carry a
front-end sales charge, CDSC or Limited CDSC.


         The privilege also extends to all purchases made at one time by an
individual; or an individual, his or her spouse and their children under 21; or
a trustee or other fiduciary of trust estates or fiduciary accounts for the
benefit of such family members (including certain employee benefit programs).


Right of Accumulation
         When you determine the availability of the reduced front-end sales
charges on Class A Shares, you can include, subject to the exceptions described
below, the total amount of any Class of shares you own of a Fund and all other
Delaware Investments mutual funds. However, you cannot include mutual fund
shares that do not carry a front-end sales charge, CDSC or Limited CDSC, unless
you acquired those shares through an exchange from a Delaware Investments mutual
fund that did carry a front-end sales charge, CDSC or Limited CDSC. If, for
example, any such purchaser has previously purchased and still holds Class A
Shares and/or shares of any other of the classes described in the previous
sentence with a value of $60,000 and subsequently purchases $40,000 at offering
price of additional shares of Class A Shares, the charge applicable to the
$40,000 purchase would currently be 3.75%. For the purpose of this calculation,
the shares presently held shall be valued at the public offering price that
would have been in effect were the shares purchased simultaneously with the
current purchase. Investors should refer to the table of sales charges for Class
A Shares to determine the applicability of the Right of Accumulation to their
particular circumstances.


12-Month Reinvestment Privilege
         Holders of Class A Shares and Class B Shares of a Fund (and of the
Institutional Class holding shares which were acquired through an exchange from
one of the other mutual funds in the Delaware Investments family offered with a
front-end sales charge) who redeem such shares have one year from the date of
redemption to reinvest all or part of their redemption proceeds in the same
Class of the Fund or in the same Class of any of the other funds in the Delaware
Investments family. In the case of Class A Shares, the reinvestment will not be
assessed a front-end sales charge and in the case of Class B Shares, the amount
of the CDSC previously charged on the redemption will be reimbursed by the
Distributor. The reinvestment will be subject to applicable eligibility and
minimum purchase requirements and must be in states where shares of such other
funds may be sold. This reinvestment privilege does not extend to Class A Shares
where the redemption of the shares triggered the payment of a Limited CDSC.
Persons investing redemption proceeds from direct investments in mutual funds in
the Delaware Investments family, offered without a front-end sales charge will
be required to pay the applicable sales charge when purchasing Class A Shares.
The reinvestment privilege does not extend to a redemption of Class C Shares.

         Any such reinvestment cannot exceed the redemption proceeds (plus any
amount necessary to purchase a full share). The reinvestment will be made at the
net asset value next determined after receipt of remittance. In the case of
Class B Shares, the time that the previous investment was held will be included
in determining any applicable CDSC due upon redemptions as well as the automatic
conversion into Class A Shares.

         A redemption and reinvestment of Class B Shares could have income tax
consequences. Shareholders will receive from the Distributor the amount of the
CDSC paid at the time of redemption as part of the reinvested shares, which may
be treated as a capital gain to the shareholder for tax purposes. It is
recommended that a tax adviser be consulted with respect to such transactions.

                                                                              53

<PAGE>

         Any reinvestment directed to a fund in which the investor does not then
have an account will be treated like all other initial purchases of the fund's
shares. Consequently, an investor should obtain and read carefully the
prospectus for the fund in which the investment is intended to be made before
investing or sending money.

         The prospectus contains more complete information about the fund,
including charges and expenses.

         Investors should consult their financial advisers or the Transfer
Agent, which also serves as the Fund's shareholder servicing agent, about the
applicability of the Class A Limited CDSC in connection with the features
described above.

Group Investment Plans
         Group Investment Plans that are not eligible to purchase shares of the
Institutional Classes may also benefit from the reduced front-end sales charges
for investments in Class A Shares, based on total plan assets. If a company has
more than one plan investing in the Delaware Investments family of funds, then
the total amount invested in all plans would be used in determining the
applicable front-end sales charge reduction upon each purchase, both initial and
subsequent, upon notification to the Fund in which the investment is being made
at the time of each such purchase. Employees participating in such Group
Investment Plans may also combine the investments made in their plan account
when determining the applicable front-end sales charge on purchases to
non-retirement investment accounts of Delaware Investments if they so notify the
Fund in connection with each purchase. For other retirement plans and special
services, see Retirement Plans for the Fund Classes under Investment Plans.


         The Limited CDSC is generally applicable to any redemptions of net
asset value purchases made on behalf of a group retirement plan on which a
dealer's commission has been paid only if such redemption is made pursuant to a
withdrawal of the entire plan from a fund in the Delaware Investments family.
See Contingent Deferred Sales Charge for Certain Redemptions of Class A Shares
Purchased at Net Asset Value under Redemption and Exchange. Notwithstanding the
foregoing, the Limited CDSC for Class A Shares on which a dealer's commission
has been paid will be waived in connection with redemptions by certain group
defined contribution retirement plans that purchase shares through a retirement
plan alliance program which requires that shares will be available at net asset
value, provided that Retirement Financial Services, Inc. either is the sponsor
of the alliance program or has a product participation agreement with the
sponsor of the alliance program that specifies that the Limited CDSC will be
waived.


The Institutional Classes
         The Institutional Class of each Fund is available for purchase only by:
(a) retirement plans introduced by persons not associated with brokers or
dealers that are primarily engaged in the retail securities business and
rollover individual retirement accounts from such plans; (b) tax-exempt employee
benefit plans of the Manager, the Sub-Adviser or their affiliates and securities
dealer firms with a selling agreement with the Distributor; (c) institutional
advisory accounts of the Manager, the Sub-Adviser or their affiliates and those
having client relationships with Delaware Investment Advisers, a division of the
Manager, or its affiliates and their corporate sponsors, as well as subsidiaries
and related employee benefit plans and rollover individual retirement accounts
from such institutional advisory accounts; (d) a bank, trust company and similar
financial institution investing for its own account or for the account of its
trust customers for whom such financial institution is exercising investment
discretion in purchasing shares of the Class, except where the investment is
part of a program that requires payment to the financial institution of a Rule
12b-1 fee; and (e) registered investment advisers investing on behalf of clients
that consist solely of institutions and high net-worth individuals having at
least $1,000,000 entrusted to the adviser for investment purposes, but only if
the adviser is not affiliated or associated with a broker or dealer and derives
compensation for its services exclusively from its clients for such advisory
services.

                                                                              54

<PAGE>


         The Institutional Class of each of Delaware Corporate Bond Fund and
Delaware Extended Duration Bond Fund is also available for purchase by clients
of brokers or dealers affiliated with a broker or dealer, if such broker or
dealer has entered into an agreement with the Distributor providing specifically
for the purchase of shares of the Classes in connection with special investment
products, such as wrap accounts or similar fee based programs.

         Investors may be charged a fee when effecting transactions in shares of
the Classes through a broker or agent that offers these special products.

         Shares of the Institutional Classes are available for purchase at net
asset value, without the imposition of a front-end or contingent deferred sales
charge and are not subject to Rule 12b-1 expenses.


INVESTMENT PLANS

Reinvestment Plan/Open Account
         Unless otherwise designated by shareholders in writing, dividends from
net investment income and distributions from realized securities profits, if
any, will be automatically reinvested in additional shares of the respective
Fund Class in which an investor has an account (based on the net asset value in
effect on the reinvestment date) and will be credited to the shareholder's
account on that date. All dividends and distributions of the Institutional
Classes are reinvested in the accounts of the holders of such shares (based on
the net asset value in effect on the reinvestment date). A confirmation of each
distribution from realized securities profits, if any, will be mailed to
shareholders in the first quarter of the fiscal year.

         Under the Reinvestment Plan/Open Account, shareholders may purchase and
add full and fractional shares to their plan accounts at any time either through
their investment dealers or by sending a check or money order to the specific
Fund and Class in which shares are being purchased. Such purchases, which must
meet the minimum subsequent purchase requirements set forth in the Prospectuses
and this Part B, are made, for Class A Shares at the public offering price, and
for Class B Shares, Class C Shares and Institutional Class shares at the net
asset value, at the end of the day of receipt. A reinvestment plan may be
terminated at any time. This plan does not assure a profit nor protect against
depreciation in a declining market.

Reinvestment of Dividends in Other Funds in the Delaware Investments Family
         Subject to applicable eligibility and minimum initial purchase
requirements and the limitations set forth below, holders of Class A, Class B
and Class C Shares may automatically reinvest dividends and/or distributions in
any of the mutual funds in the Delaware Investments family, including the Funds,
in states where their shares may be sold. Such investments will be at net asset
value at the close of business on the reinvestment date without any front-end
sales charge or service fee. The shareholder must notify the Transfer Agent in
writing and must have established an account in the fund into which the
dividends and/or distributions are to be invested. Any reinvestment directed to
a fund in which the investor does not then have an account will be treated like
all other initial purchases of a fund's shares. Consequently, an investor should
obtain and read carefully the prospectus for the fund in which the investment is
intended to be made before investing or sending money. The prospectus contains
more complete information about the fund, including charges and expenses.

         Subject to the following limitations, dividends and/or distributions
from other funds in the Delaware Investments family may be invested in shares of
the Funds, provided an account has been established. Dividends from Class A
Shares may not be directed to Class B Shares or Class C Shares. Dividends from
Class B Shares may only be directed to other Class B Shares and dividends from
Class C Shares may only be directed to other Class C Shares.

        Capital gains and/or dividend distributions for participants in the
following retirement plans are automatically reinvested into the same Delaware
Investments fund in which their investments are held: SAR/SEP, SEP/IRA, SIMPLE
IRA, SIMPLE 401(k), Profit Sharing and Money Purchase Pension Plans, 401(k)
Defined Contribution Plans, or 403(b)(7) or 457 Deferred Compensation Plans.


                                                                              55

Investing by Exchange
         If you have an investment in another mutual fund in the Delaware
Investments family, you may write and authorize an exchange of part or all of
your investment into shares of a Fund. If you wish to open an account by
exchange, call the Shareholder Service Center for more information. All
exchanges are subject to the eligibility and minimum purchase requirements set
forth in each Fund's prospectus. See Redemption and Exchange for more complete
information concerning your exchange privileges.

         Holders of Class A Shares of a Fund may exchange all or part of their
shares for certain of the shares of other funds in the Delaware Investments
family, including other Class A Shares, but may not exchange their Class A
Shares for Class B Shares or Class C Shares of the Fund or of any other fund in
the Delaware Investments family. Holders of Class B Shares of a Fund are
permitted to exchange all or part of their Class B Shares only into Class B
Shares of other Delaware Investments funds. Similarly, holders of Class C Shares
of a Fund are permitted to exchange all or part of their Class C Shares only
into Class C Shares of other Delaware Investments funds. Class B Shares of a
Fund and Class C Shares of a Fund acquired by exchange will continue to carry
the CDSC and, in the case of Class B Shares, the automatic conversion schedule
of the fund from which the exchange is made. The holding period of Class B
Shares of a Fund acquired by exchange will be added to that of the shares that
were exchanged for purposes of determining the time of the automatic conversion
into Class A Shares of the Fund.

         Permissible exchanges into Class A Shares of a Fund will be made
without a front-end sales charge, except for exchanges of shares that were not
previously subject to a front-end sales charge (unless such shares were acquired
through the reinvestment of dividends). Permissible exchanges into Class B
Shares or Class C Shares of a Fund will be made without the imposition of a CDSC
by the fund from which the exchange is being made at the time of the exchange.

Investing by Electronic Fund Transfer
         Direct Deposit Purchase Plan -- Investors may arrange for a Fund to
accept for investment in Class A, Class B or Class C Shares, through an agent
bank, preauthorized government or private recurring payments. This method of
investment assures the timely credit to the shareholder's account of payments
such as social security, veterans' pension or compensation benefits, federal
salaries, Railroad Retirement benefits, private payroll checks, dividends, and
disability or pension fund benefits. It also eliminates lost, stolen and delayed
checks.

         Automatic Investing Plan -- Shareholders of Class A, Class B and Class
C Shares may make automatic investments by authorizing, in advance, monthly or
quarterly payments directly from their checking account for deposit into their
Fund account. This type of investment will be handled in either of the following
ways. (1) If the shareholder's bank is a member of the National Automated
Clearing House Association ("NACHA"), the amount of the investment will be
electronically deducted from his or her account by Electronic Fund Transfer
("EFT"). The shareholder's checking account will reflect a debit each month at a
specified date although no check is required to initiate the transaction. (2) If
the shareholder's bank is not a member of NACHA, deductions will be made by
preauthorized checks, known as Depository Transfer Checks. Should the
shareholder's bank become a member of NACHA in the future, his or her
investments would be handled electronically through EFT.

         This option is not available to participants in the following plans:
SAR/SEP, SEP/IRA, SIMPLE IRA, SIMPLE 401(k), Profit Sharing and Money Purchase
Pension Plans, 401(k) Defined Contribution Plans, or 403(b)(7) or 457 Deferred
Compensation Plans.

                                      * * *



                                                                              56
<PAGE>

         Initial investments under the Direct Deposit Purchase Plan and the
Automatic Investing Plan must be for $250 or more and subsequent investments
under such Plans must be for $25 or more. An investor wishing to take advantage
of either service must complete an authorization form. Either service can be
discontinued by the shareholder at any time without penalty by giving written
notice.

         Payments to a Fund from the federal government or its agencies on
behalf of a shareholder may be credited to the shareholder's account after such
payments should have been terminated by reason of death or otherwise. Any such
payments are subject to reclamation by the federal government or its agencies.
Similarly, under certain circumstances, investments from private sources may be
subject to reclamation by the transmitting bank. In the event of a reclamation,
a Fund may liquidate sufficient shares from a shareholder's account to reimburse
the government or the private source. In the event there are insufficient shares
in the shareholder's account, the shareholder is expected to reimburse the Fund.

Direct Deposit Purchases by Mail
         Shareholders may authorize a third party, such as a bank or employer,
to make investments directly to their Fund accounts. A Fund will accept these
investments, such as bank-by-phone, annuity payments and payroll allotments, by
mail directly from the third party. Investors should contact their employers or
financial institutions who in turn should contact Income Funds for proper
instructions.

MoneyLine(SM) On Demand
        You or your investment dealer may request purchases of Fund Class shares
by phone using MoneyLine(SM) On Demand. When you authorize a Fund to accept
such requests from you or your investment dealer, funds will be withdrawn from
(for share purchases) your predesignated bank account. Your request will be
processed the same day if you call prior to 4 p.m., Eastern time. There is a $25
minimum and $50,000 maximum limit for MoneyLine(SM) On Demand transactions.

        It may take up to four business days for the transactions to be
completed. You can initiate this service by completing an Account Services form.
If your name and address are not identical to the name and address on your Fund
account, you must have your signature guaranteed. The Funds do not charge a fee
for this service; however, your bank may charge a fee.

Wealth Builder Option
         Shareholders can use the Wealth Builder Option to invest in the Fund
Classes through regular liquidations of shares in their accounts in other mutual
funds in the Delaware Investments family. Shareholders of the Fund Classes may
elect to invest in one or more of the other mutual funds in the Delaware
Investments family through the Wealth Builder Option.



                                                                              57
<PAGE>

         Under this automatic exchange program, shareholders can authorize
regular monthly investments (minimum of $100 per fund) to be liquidated from
their account and invested automatically into other mutual funds in the Delaware
Investments family, subject to the conditions and limitations set forth in the
Fund Classes' Prospectuses. The investment will be made on the 20th day of each
month (or, if the fund selected is not open that day, the next business day) at
the public offering price or net asset value, as applicable, of the fund
selected on the date of investment. No investment will be made for any month if
the value of the shareholder's account is less than the amount specified for
investment.

         Periodic investment through the Wealth Builder Option does not insure
profits or protect against losses in a declining market. The price of the fund
into which investments are made could fluctuate. Since this program involves
continuous investment regardless of such fluctuating value, investors selecting
this option should consider their financial ability to continue to participate
in the program through periods of low fund share prices. This program involves
automatic exchanges between two or more fund accounts and is treated as a
purchase of shares of the fund into which investments are made through the
program. See Redemption and Exchange for a brief summary of the tax consequences
of exchanges. Shareholders can terminate their participation at any time by
giving written notice to their Fund.

         This option is not available to participants in the following plans:
SAR/SEP, SEP/IRA, SIMPLE IRA, SIMPLE 401(k), Profit Sharing and Money Purchase
Pension Plans, 401(k) Defined Contribution Plans, or 403(b)(7) or 457 Deferred
Compensation Plans. This option also is not available to shareholders of the
Institutional Classes.

Asset Planner
         To invest in the funds in the Delaware Investments family using the
Asset Planner asset allocation service, you should complete a Asset Planner
Account Registration Form, which is available only from a financial adviser or
investment dealer. Effective September 1, 1997, the Asset Planner Service is
only available to financial advisers or investment dealers who have previously
used this service. The Asset Planner service offers a choice of four predesigned
asset allocation strategies (each with a different risk/reward profile) in
predetermined percentages in funds in the Delaware Investments family. With the
help of a financial adviser, you may also design a customized asset allocation
strategy.

         The sales charge on an investment through the Asset Planner service is
determined by the individual sales charges of the underlying funds and their
percentage allocation in the selected Strategy. Exchanges from existing Delaware
Investments accounts into the Asset Planner service may be made at net asset
value under the circumstances described under Investing by Exchange. Also see
Buying Class A Shares at Net Asset Value. The minimum initial investment per
Strategy is $2,000; subsequent investments must be at least $100. Individual
fund minimums do not apply to investments made using the Asset Planner service.
Class A, Class B and Class C Shares are available through the Asset Planner
service. Generally, only shares within the same class may be used within the
same Strategy. However, Class A Shares of the Fund and of other funds in the
Delaware Investments family may be used in the same Strategy with consultant
class shares that are offered by certain other Delaware Investments funds.

         An annual maintenance fee, currently $35 per Strategy, is due at the
time of initial investment and by September 30 of each subsequent year. The fee,
payable to Delaware Service Company, Inc. to defray extra costs associated with
administering the Asset Planner service, will be deducted automatically from one
of the funds within your Asset Planner account if not paid by September 30.
However, effective November 1, 1996, the annual maintenance fee is waived until
further notice. Investors who utilize the Asset Planner for an IRA will continue
to pay an annual IRA fee of $15 per Social Security number.

                                                                              58
<PAGE>

         Investors will receive a customized quarterly Strategy Report
summarizing all Asset Planner investment performance and account activity during
the prior period. Confirmation statements will be sent following all
transactions other than those involving a reinvestment of distributions.

         Certain shareholder services are not available to investors using the
Asset Planner service, due to its special design. These include Delaphone,
Checkwriting, Wealth Builder Option and Letter of Intention. Systematic
Withdrawal Plans are available after the account has been open for two years.

Retirement Plans for the Fund Classes
         An investment in a Fund may be suitable for tax-deferred retirement
plans. Delaware Investments offers a full spectrum of retirement plans,
including the 401(k) deferred compensation plan, Individual Retirement Account
("IRA") and the new Roth IRA and Education IRA.

         Among the retirement plans that Delaware Investments offers, Class B
Shares are available for investment only by Individual Retirement Accounts,
SIMPLE IRAs, Roth IRAs, Education IRAs, Simplified Employee Pension Plans,
Salary Reduction Simplified Employee Pension Plans and 403(b) and 457 Deferred
Compensation Plans. The CDSC may be waived on certain redemptions of Class B
Shares and Class C Shares. See Waiver of Contingent Deferred Sales Charge under
Redemption and Exchange for a list of the instances in which the CDSC is waived.

         Purchases of Class B Shares are subject to a maximum purchase
limitation of $250,000 for retirement plans. Purchases of Class C Shares must be
in an amount that is less than $1,000,000 for such plans. The maximum purchase
limitations apply only to the initial purchase of shares by the retirement plan.

         Minimum investment limitations generally applicable to other investors
do not apply to retirement plans other than Individual Retirement Accounts, for
which there is a minimum initial purchase of $250 and a minimum subsequent
purchase of $25 regardless of which Class is selected. Retirement plans may be
subject to plan establishment fees, annual maintenance fees and/or other
administrative or trustee fees. Fees are based upon the number of participants
in the plan as well as the services selected. Additional information about fees
is included in retirement plan materials. Fees are quoted upon request. Annual
maintenance fees may be shared by Delaware Management Trust Company, the
Transfer Agent, other affiliates of the Manager and others that provide services
to such plans.

         Certain shareholder investment services available to non-retirement
plan shareholders may not be available to retirement plan shareholders. Certain
retirement plans may qualify to purchase Institutional Class shares. See
Institutional Classes, above. For additional information on any of the Plans and
Delaware's retirement services, call the Shareholder Service Center telephone
number.

         It is advisable for an investor considering any one of the retirement
plans described below to consult with an attorney, accountant or a qualified
retirement plan consultant. For further details, including applications for any
of these plans, contact your investment dealer or the Distributor.

         Taxable distributions from the retirement plans described below may be
subject to withholding.

         Please contact your investment dealer or the Distributor for the
special application forms required for the plans described below.

                                                                              59

Prototype Profit Sharing or Money Purchase Pension Plans
         Prototype Plans are available for self-employed individuals,
partnerships, corporations and other eligible forms of organizations. These
plans can be maintained as Section 401(k), profit sharing or money purchase
pension plans. Contributions may be invested only in Class A Shares and Class C
Shares.

Individual Retirement Account ("IRA")
         A document is available for an individual who wants to establish an IRA
and make contributions which may be tax-deductible, even if the individual is
already participating in an employer-sponsored retirement plan. Even if
contributions are not deductible for tax purposes, as indicated below, earnings
will be tax-deferred. In addition, an individual may make contributions on
behalf of a spouse who has no compensation for the year; however, participation
may be restricted based on certain income limits.

IRA Disclosures
         The Taxpayer Relief Act of 1997 provides new opportunities for
investors. Individuals have five types of tax-favored IRA accounts that can be
utilized depending on the individual's circumstances. A new Roth IRA and
Education IRA are available in addition to the existing deductible IRA and
non-deductible IRA.

Deductible and Non-deductible IRAs
         An individual can contribute up to $2,000 in his or her IRA each year.
Contributions may or may not be deductible depending upon the taxpayer's
adjusted gross income ("AGI") and whether the taxpayer is an active participant
in an employer sponsored retirement plan. Even if a taxpayer is an active
participant in an employer sponsored retirement plan, the full $2,000 is still
available if the taxpayer's AGI is below $32,000 ($52,000 for taxpayers filing
joint returns) for years beginning after December 31, 1997. A partial deduction
is allowed for married couples with income between $52,000 and $62,000, and for
single individuals with incomes between $32,000 and $42,000. These income
phase-out limits reach $80,000-$100,000 in 2007 for joint filers and
$50,000-$60,000 in 2005 for single filers. No deductions are available for
contributions to IRAs by taxpayers whose AGI after IRA deductions exceeds the
maximum income limit established for each year and who are active participants
in an employer sponsored retirement plan.

         Taxpayers who are not allowed deductions on IRA contributions still can
make non-deductible IRA contributions of as much as $2,000 for each working
spouse and defer taxes on interest or other earnings from the IRAs.

         Under the new law, a married individual is not considered an active
participant in an employer sponsored retirement plan merely because the
individual's spouse is an active participant if the couple's combined AGI is
below $150,000. The maximum deductible IRA contribution for a married individual
who is not an active participant, but whose spouse is, is phased out for
combined AGI between $150,000 and $160,000.

Conduit (Rollover) IRAs
         Certain individuals who have received or are about to receive eligible
rollover distributions from an employer-sponsored retirement plan or another IRA
may rollover the distribution tax-free to a Conduit IRA. The rollover of the
eligible distribution must be completed by the 60th day after receipt of the
distribution; however, if the rollover is in the form of a direct
trustee-to-trustee transfer without going through the distributee's hand, the
60-day limit does not apply.

         A distribution qualifies as an "eligible rollover distribution" if it
is made from a qualified retirement plan, a 403(b) plan or another IRA and does
not constitute one of the following:

                                                                              60
<PAGE>

         (1)  Substantially equal periodic payments over the employee's life or
              life expectancy or the joint lives or life expectancies of the
              employee and his/her designated beneficiary;

         (2)  Substantially equal installment payments for a period certain of
              10 or more years;

         (3)  A distribution, all of which represents a required minimum
              distribution after attaining age 70 1/2;

         (4)  A distribution due to a Qualified Domestic Relations Order to an
              alternate payee who is not the spouse (or former spouse) of the
              employee; and

         (5)  A distribution of after-tax contributions which is not includable
              in income.

Roth IRAs
         For taxable years beginning after December 31, 1997, non-deductible
contributions of up to $2,000 per year can be made to a new Roth IRA. The $2,000
annual limit is reduced by any contributions to a deductible or nondeductible
IRA for the same year. The maximum contribution that can be made to a Roth IRA
is phased out for single filers with AGI between $95,000 and $110,000, and for
couples filing jointly with AGI between $150,000 and $160,000. Qualified
distributions from a Roth IRA would be exempt from federal taxes. Qualified
distributions are distributions (1) made after the five-taxable year period
beginning with the first taxable year for which a contribution was made to a
Roth IRA and (2) that are (a) made on or after the date on which the individual
attains age 59 1/2, (b) made to a beneficiary on or after the death of the
individual, (c) attributed to the individual being disabled, or (d) for a
qualified special purpose (e.g., first time homebuyer expenses).

         Distributions that are not qualified distributions would always be
tax-free if the taxpayer is withdrawing contributions, not accumulated earnings.

         Taxpayers with AGI of $100,000 or less are eligible to convert an
existing IRA (deductible, nondeductible and conduit) to a Roth IRA. Earnings and
contributions from a deductible IRA are subject to a tax upon conversion;
however, no 10% excise tax for early withdrawal would apply. If the conversion
is done prior to January 1, 1999, then the income from the conversion can be
included in income ratably over a four-year period beginning with the year of
conversion.

Education IRAs
         For taxable years beginning after December 31, 1997, an Education IRA
has been created exclusively for the purpose of paying qualified higher
education expenses. Taxpayers can make non-deductible contributions up to $500
per year per beneficiary. The $500 annual limit is in addition to the $2,000
annual contribution limit applicable to IRAs and Roth IRAs. Eligible
contributions must be in cash and made prior to the date the beneficiary reaches
age 18. Similar to the Roth IRA, earnings would accumulate tax-free. There is no
requirement that the contributor be related to the beneficiary, and there is no
limit on the number of beneficiaries for whom one contributor can establish
Education IRAs. In addition, multiple Education IRAs can be created for the same
beneficiaries, however, the contribution limit of all contributions for a single
beneficiary cannot exceed $500 annually.

         This $500 annual contribution limit for Education IRAs is phased out
ratably for single contributors with modified AGI between $95,000 and $110,000,
and for couples filing jointly with modified AGI of between $150,000 and
$160,000. Individuals with modified AGI above the phase-out range are not
allowed to make contributions to an Education IRA established on behalf of any
other individual.

                                                                              61
<PAGE>

         Distributions from an Education IRA are excludable from gross income to
the extent that the distribution does not exceed qualified higher education
expenses incurred by the beneficiary during the year the distribution is made
regardless of whether the beneficiary is enrolled at an eligible educational
institution on a full-time, half-time, or less than half-time basis.

         Any balance remaining in an Education IRA at the time a beneficiary
becomes 30 years old must be distributed, and the earnings portion of such a
distribution will be includible in gross income of the beneficiary and subject
to an additional 10% penalty tax if the distribution is not for qualified higher
educations expenses. Tax-free (and penalty-free) transfers and rollovers of
account balances from one Education IRA benefiting one beneficiary to another
Education IRA benefiting a different beneficiary (as well as redesignations of
the named beneficiary) is permitted, provided that the new beneficiary is a
member of the family of the old beneficiary and that the transfer or rollover is
made before the time the old beneficiary reaches age 30 and the new beneficiary
reaches age 18.

         A company or association may establish a Group IRA or Group Roth IRA
for employees or members who want to purchase shares of a Fund.

         Investments generally must be held in the IRA until age 59 1/2 in order
to avoid premature distribution penalties, but distributions generally must
commence no later than April 1 of the calendar year following the year in which
the participant reaches age 70 1/2. Individuals are entitled to revoke the
account, for any reason and without penalty, by mailing written notice of
revocation to Delaware Management Trust Company within seven days after the
receipt of the IRA Disclosure Statement or within seven days after the
establishment of the IRA, except, if the IRA is established more than seven days
after receipt of the IRA Disclosure Statement, the account may not be revoked.
Distributions from the account (except for the pro-rata portion of any
nondeductible contributions) are fully taxable as ordinary income in the year
received. Excess contributions removed after the tax filing deadline, plus
extensions, for the year in which the excess contributions were made are subject
to a 6% excise tax on the amount of excess. Premature distributions
(distributions made before age 59 1/2, except for death, disability and certain
other limited circumstances) will be subject to a 10% excise tax on the amount
prematurely distributed, in addition to the income tax resulting from the
distribution. For information concerning the applicability of a CDSC upon
redemption of Class B Shares and Class C Shares, see Contingent Deferred Sales
Charge - Class B Shares and Class C Shares under Classes of Shares in the
Prospectus for Class B Shares and Class C Shares.

         Effective January 1, 1997, the 10% premature distribution penalty will
not apply to distributions from an IRA that are used to pay medical expenses in
excess of 7.5% of adjusted gross income or to pay health insurance premiums by
an individual who has received unemployment compensation for 12 consecutive
weeks. In addition, effective January 1, 1998, the new law allows for premature
distribution without a 10% penalty if (i) the amounts are used to pay qualified
higher education expenses (including graduate level courses) of the taxpayer,
the taxpayer's spouse or any child or grandchild of the taxpayer or the
taxpayer's spouse, or (ii) used to pay acquisition costs of a principle
residence for the purchase of a first-time home by the taxpayer, taxpayer's
spouse or any child or grandchild of the taxpayer or the taxpayer's spouse. A
qualified first-time homebuyer is someone who has had no ownership interest in a
residence during the past two years. The aggregate amount of distribution for
first-time home purchases cannot exceed a lifetime cap of $10,000.


Simplified Employee Pension Plan ("SEP/IRA")
         A SEP/IRA may be established by an employer who wishes to sponsor a
tax-sheltered retirement program by making contributions on behalf of all
eligible employees. Each of the Classes is available for investment by a
SEP/IRA.

                                                                              62
<PAGE>

Salary Reduction Simplified Employee Pension Plan ("SAR/SEP")
         Although new SAR/SEP plans may not be established after December 31,
1996, existing plans may continue to be maintained by employers having 25 or
fewer employees. An employer may elect to make additional contributions to such
existing plans.

Prototype 401(k) Defined Contribution Plan
         Section 401(k) of the Code permits employers to establish qualified
plans based on salary deferral contributions. Effective January 1, 1997,
non-governmental tax-exempt organizations may establish 401(k) plans. Plan
documents are available to enable employers to establish a plan. An employer may
also elect to make profit sharing contributions and/or matching contributions
with investments in only Class A Shares and Class C Shares or certain other
funds in the Delaware Investments family. Purchases under the Plan may be
combined for purposes of computing the reduced front-end sales charge applicable
to Class A Shares as set forth in the table the Prospectuses for the Fund
Classes.

Deferred Compensation Plan for Public Schools and Non-Profit Organizations
("403(b)(7)")
         Section 403(b)(7) of the Code permits public school systems and certain
non-profit organizations to use mutual fund shares held in a custodial account
to fund deferred compensation arrangements for their employees. A custodial
account agreement is available for those employers who wish to purchase shares
of any of the Classes in conjunction with such an arrangement. Purchases under
the Plan may be combined for purposes of computing the reduced front-end sales
charge applicable to Class A Shares as set forth in the table the Prospectuses
for the Fund Classes.

Deferred Compensation Plan for State and Local Government Employees ("457")
         Section 457 of the Code permits state and local governments, their
agencies and certain other entities to establish a deferred compensation plan
for their employees who wish to participate. This enables employees to defer a
portion of their salaries and any federal (and possibly state) taxes thereon.
Such plans may invest in shares of the Fund. Although investors may use their
own plan, there is available a Delaware Investments 457 Deferred Compensation
Plan. Interested investors should contact the Distributor or their investment
dealers to obtain further information. Purchases under the Plan may be combined
for purposes of computing the reduced front-end sales charge applicable to Class
A Shares as set forth in the table the Prospectuses for the Fund Classes.

SIMPLE IRA
         A SIMPLE IRA combines many of the features of an IRA and a 401(k) Plan
but is easier to administer than a typical 401(k) Plan. It requires employers to
make contributions on behalf of their employees and also has a salary deferral
feature that permits employees to defer a portion of their salary into the plan
on a pre-tax basis. A SIMPLE IRA is available only to plan sponsors with 100 or
fewer employees.

SIMPLE 401(k)
         A SIMPLE 401(k) is like a regular 401(k) except that it is available
only to plan sponsors with 100 or fewer employees and, in exchange for mandatory
plan sponsor contributions, discrimination testing is not required.

                                                                              63

DETERMINING OFFERING PRICE AND NET ASSET VALUE

         Orders for purchases of Class A Shares are effected at the offering
price next calculated by the Fund in which shares are being purchased after
receipt of the order by the Fund or its agent or certain other authorized
persons. See Distribution and Service under Investment Management Agreement and
Sub-Advisory Agreement. Orders for purchases of Class B Shares, Class C Shares
and the Institutional Classes are effected at the net asset value per share next
calculated by the Fund in which shares are being purchased after receipt of the
order by the Fund, its agent or certain other authorized persons. Selling
dealers are responsible for transmitting orders promptly.

         The offering price for Class A Shares consists of the net asset value
per share plus any applicable front-end sales charges. Offering price and net
asset value are computed as of the close of regular trading on the New York
Stock Exchange (ordinarily, 4 p.m., Eastern time) on days when the Exchange is
open. The New York Stock Exchange is scheduled to be open Monday through Friday
throughout the year except for days on which the following holidays are
observed: New Year's Day, Martin Luther King, Jr.'s Birthday, Presidents' Day,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas. When the New York Stock Exchange is closed, the Funds will generally
be closed, pricing calculations will not be made and purchase and redemption
orders will not be processed.

         An example showing how to calculate the net asset value per share and,
in the case of Class A Shares, the offering price per share, will be included in
the Fund's financial statements which are incorporated by reference into this
Part B.

         Each Fund's net asset value per share is computed by adding the value
of all the securities and other assets in the portfolio, deducting any
liabilities and dividing by the number of shares outstanding. Expenses and fees
are accrued daily. In determining a Fund's total net assets, portfolio
securities listed or traded on a national securities exchange, except for bonds,
are valued at the last sale price on the exchange upon which such securities are
primarily traded. Securities not traded on a particular day, over-the-counter
securities and government and agency securities are valued at the mean value
between bid and asked prices. Money market instruments having a maturity of less
than 60 days are valued at amortized cost. Debt securities (other than
short-term obligations) are valued on the basis of valuations provided by a
pricing service when such prices are believed to reflect the fair value of such
securities. Foreign securities, currencies and other assets denominated in
foreign currencies are translated into U.S. dollars at the exchange rate of such
currencies against the U.S. dollar, as provided by an independent pricing
service. Use of a pricing service has been approved by the Board of Trustees.
Prices provided by a pricing service take into account appropriate factors such
as institutional trading in similar groups of securities, yield, quality, coupon
rate, maturity, type of issue, trading characteristics and other market data. If
no quotations are available, for all other securities, we use methods approved
by the Board of Trustees that are designed to price securities at their fair
market value.



                                                                              64
<PAGE>

         Each Class of a Fund will bear, pro-rata, all of the common expenses of
that Fund. The net asset values of all outstanding shares of each Class of a
Fund will be computed on a pro-rata basis for each outstanding share based on
the proportionate participation in that Fund represented by the value of shares
of that Class. All income earned and expenses incurred by a Fund will be borne
on a pro-rata basis by each outstanding share of a Class, based on each Class'
percentage in the Fund represented by the value of shares of such Classes,
except that Institutional Classes will not incur any of the expenses under
Income Funds' 12b-1 Plans and Class A, Class B and Class C Shares alone will
bear the 12b-1 Plan expenses payable under their respective Plans. Due to the
specific distribution expenses and other costs that may be allocable to each
Class of a Fund, the dividends paid to each Class of the Fund may vary. The net
asset value per share of each Class of a Fund is expected to be equivalent.

REDEMPTION AND EXCHANGE

        You can redeem or exchange your shares in a number of different ways.
The exchange service is useful if your investment requirements change and you
want an easy way to invest in other equity funds, tax-advantaged funds, bond
funds or money market funds. This service is also useful if you are anticipating
a major expenditure and want to move a portion of your investment into a fund
that has the checkwriting feature. Exchanges are subject to the requirements of
each fund. Further, in order for an exchange to be processed, shares of the fund
being acquired must be registered in the state where the acquiring shareholder
resides. An exchange constitutes, for tax purposes, the sale of one fund and the
purchase of another. The sale may involve a capital gain or loss to the
shareholder for federal income tax purposes. You may want to consult your
financial adviser or investment dealer to discuss which funds in Delaware
Investments will best meet your changing objectives, and the consequences of any
exchange transaction. You may also call the Delaware Investments directly for
fund information.

        Your shares will be redeemed or exchanged at a price based on the net
asset value next determined after a Fund receives your request in good order,
subject, in the case of a redemption, to any applicable CDSC or Limited CDSC.
For example, redemption or exchange requests received in good order after the
time the offering price and net asset value of shares are determined will be
processed on the next business day. A shareholder submitting a redemption
request may indicate that he or she wishes to receive redemption proceeds of a
specific dollar amount. In the case of such a request, and in the case of
certain redemptions from retirement plan accounts, a Fund will redeem the number
of shares necessary to deduct the applicable CDSC in the case of Class B Shares
and Class C Shares, and, if applicable, the Limited CDSC in the case of Class A
Shares and tender to the shareholder the requested amount, assuming the
shareholder holds enough shares in his or her account for the redemption to be
processed in this manner. Otherwise, the amount tendered to the shareholder upon
redemption will be reduced by the amount of the applicable CDSC or Limited CDSC.
Redemption proceeds will be distributed promptly, as described below, but not
later than seven days after receipt of a redemption request.

        Except as noted below, for a redemption request to be in "good order,"
you must provide your account number, account registration, and the total number
of shares or dollar amount of the transaction. For exchange requests, you must
also provide the name of the fund in which you want to invest the proceeds.
Exchange instructions and redemption requests must be signed by the record
owner(s) exactly as the shares are registered. You may request a redemption or
an exchange by calling the Shareholder Service Center at 800-523-1918. Each Fund
may suspend, terminate, or amend the terms of the exchange privilege upon 60
days' written notice to shareholders.

                                                                              65
<PAGE>

        In addition to redemption of Fund shares, the Distributor, acting as
agent of the Funds, offers to repurchase Fund shares from broker/dealers acting
on behalf of shareholders. The redemption or repurchase price, which may be more
or less than the shareholder's cost, is the net asset value per share next
determined after receipt of the request in good order by the respective Fund,
its agent, or certain authorized persons, subject to applicable CDSC or Limited
CDSC. This is computed and effective at the time the offering price and net
asset value are determined. See Determining Offering Price and Net Asset Value.
The Funds and the Distributor end their business days at 5 p.m., Eastern time.
This offer is discretionary and may be completely withdrawn without further
notice by the Distributor.

        Orders for the repurchase of Fund shares which are submitted to the
Distributor prior to the close of its business day will be executed at the net
asset value per share computed that day (subject to the applicable CDSC or
Limited CDSC), if the repurchase order was received by the broker/dealer from
the shareholder prior to the time the offering price and net asset value are
determined on such day. The selling dealer has the responsibility of
transmitting orders to the Distributor promptly. Such repurchase is then settled
as an ordinary transaction with the broker/dealer (who may make a charge to the
shareholder for this service) delivering the shares repurchased.

        Payment for shares redeemed will ordinarily be mailed the next business
day, but in no case later than seven days, after receipt of a redemption request
in good order by the Fund or certain other authorized persons (see Distribution
and Service under Investment Management Agreement and Sub-Advisory Agreement);
provided, however, that each commitment to mail or wire redemption proceeds by a
certain time, as described below, is modified by the qualifications described in
the next paragraph.

        Each Fund will process written and telephone redemption requests to the
extent that the purchase orders for the shares being redeemed have already
settled. Each Fund will honor redemption requests as to shares for which a check
was tendered as payment, but a Fund will not mail or wire the proceeds until it
is reasonably satisfied that the purchase check has cleared, which may take up
to 15 days from the purchase date. You can avoid this potential delay if you
purchase shares by wiring Federal Funds. Each Fund reserves the right to reject
a written or telephone redemption request or delay payment of redemption
proceeds if there has been a recent change to the shareholder's address of
record.

        If a shareholder has been credited with a purchase by a check which is
subsequently returned unpaid for insufficient funds or for any other reason, the
Fund involved will automatically redeem from the shareholder's account the
shares purchased by the check plus any dividends earned thereon. Shareholders
may be responsible for any losses to a Fund or to the Distributor.

        In case of a suspension of the determination of the net asset value
because the New York Stock Exchange is closed for other than weekends or
holidays, or trading thereon is restricted or an emergency exists as a result of
which disposal by a Fund of securities owned by it is not reasonably practical,
or it is not reasonably practical for a Fund fairly to value its assets, or in
the event that the SEC has provided for such suspension for the protection of
shareholders, a Fund may postpone payment or suspend the right of redemption or
repurchase. In such case, the shareholder may withdraw the request for
redemption or leave it standing as a request for redemption at the net asset
value next determined after the suspension has been terminated.

        Payment for shares redeemed or repurchased may be made either in cash or
kind, or partly in cash and partly in kind. Any portfolio securities paid or
distributed in kind would be valued as described in Determining Offering Price
and Net Asset Value. Subsequent sale by an investor receiving a distribution in
kind could result in the payment of brokerage commissions. However, Income Funds
has elected to be governed by Rule 18f-1 under the 1940 Act pursuant to which
each Fund is obligated to redeem shares solely in cash up to the lesser of
$250,000 or 1% of the net asset value of such Fund during any 90-day period for
any one shareholder.

                                                                              66
<PAGE>

        The value of a Fund's investments is subject to changing market prices.
Thus, a shareholder reselling shares to a Fund may sustain either a gain or
loss, depending upon the price paid and the price received for such shares.

        Certain redemptions of Class A Shares purchased at net asset value may
result in the imposition of a Limited CDSC. See Contingent Deferred Sales Charge
for Certain Redemptions of Class A Shares Purchased at Net Asset Value, below.
Class B Shares are subject to a CDSC of: (i) 4% if shares are redeemed during
the first two years following purchase; (ii) 3% if shares are redeemed during
the third or fourth year following purchase; (iii) 2% if shares are redeemed
during the fifth year following purchase; (iv) 1% if shares are redeemed during
the sixth year following purchase; (v) and 0% thereafter. Class C Shares are
subject to a CDSC of 1% if shares are redeemed within 12 months following
purchase. See Contingent Deferred Sales Charge - Class B Shares and Class C
Shares under Purchasing Shares. Except for the applicable CDSC or Limited CDSC
and, with respect to the expedited payment by wire described below for which, in
the case of the Fund Classes, there may be a bank wiring cost, neither the Funds
nor the Distributor charges a fee for redemptions or repurchases, but such fees
could be charged at any time in the future.

        Holders of Class B Shares or Class C Shares that exchange their shares
("Original Shares") for shares of other funds in the Delaware Investments (in
each case, "New Shares") in a permitted exchange, will not be subject to a CDSC
that might otherwise be due upon redemption of the Original Shares. However,
such shareholders will continue to be subject to the CDSC and, in the case of
Class B Shares, the automatic conversion schedule of the Original Shares as
described in this Part B and any CDSC assessed upon redemption will be charged
by the fund from which the Original Shares were exchanged. In an exchange of
Class B Shares from a Fund, the Fund's CDSC schedule may be higher than the CDSC
schedule relating to the New Shares acquired as a result of the exchange. For
purposes of computing the CDSC that may be payable upon a disposition of the New
Shares, the period of time that an investor held the Original Shares is added to
the period of time that an investor held the New Shares. With respect to Class B
Shares, the automatic conversion schedule of the Original Shares may be longer
than that of the New Shares. Consequently, an investment in New Shares by
exchange may subject an investor to the higher 12b-1 fees applicable to Class B
Shares of a Fund for a longer period of time than if the investment in New
Shares were made directly.

Written Redemption
        You can write to each Fund at 1818 Market Street, Philadelphia, PA 19103
to redeem some or all of your shares. The request must be signed by all owners
of the account or your investment dealer of record. For redemptions of more than
$50,000, or when the proceeds are not sent to the shareholder(s) at the address
of record, the Funds require a signature by all owners of the account and a
signature guarantee for each owner. A signature guarantee can be obtained from a
commercial bank, a trust company or a member of a Securities Transfer
Association Medallion Program ("STAMP"). Each Fund reserves the right to reject
a signature guarantee supplied by an eligible institution based on its
creditworthiness. The Funds may require further documentation from corporations,
executors, retirement plans, administrators, trustees or guardians.

        Payment is normally mailed the next business day after receipt of your
redemption request. If your Class A Shares or Institutional Class shares are in
certificate form, the certificate(s) must accompany your request and also be in
good order. Certificates are issued for Class A Shares and Institutional Class
shares only if a shareholder submits a specific request. Certificates are not
issued for Class B Shares or Class C Shares.

Written Exchange
        You may also write to each Fund (at 1818 Market Street, Philadelphia, PA
19103) to request an exchange of any or all of your shares into another mutual
fund in Delaware Investments, subject to the same conditions and limitations as
other exchanges noted above and in the Prospectuses.

                                                                              67

Telephone Redemption and Exchange
        To get the added convenience of the telephone redemption and exchange
methods, you must have the Transfer Agent hold your shares (without charge) for
you. If you choose to have your Class A Shares or Institutional Class shares in
certificate form, you may redeem or exchange only by written request and you
must return your certificates.

        The Telephone Redemption - Check to Your Address of Record service and
the Telephone Exchange service, both of which are described below, are
automatically provided unless you notify the Fund in which you have your account
in writing that you do not wish to have such services available with respect to
your account. Each Fund reserves the right to modify, terminate or suspend these
procedures upon 60 days' written notice to shareholders. It may be difficult to
reach the Funds by telephone during periods when market or economic conditions
lead to an unusually large volume of telephone requests.

        Neither the Funds nor their Transfer Agent is responsible for any
shareholder loss incurred in acting upon written or telephone instructions for
redemption or exchange of Fund shares which are reasonably believed to be
genuine. With respect to such telephone transactions, each Fund will follow
reasonable procedures to confirm that instructions communicated by telephone are
genuine (including verification of a form of personal identification) as, if it
does not, such Fund or the Transfer Agent may be liable for any losses due to
unauthorized or fraudulent transactions. Telephone instructions received by the
Fund Classes are generally tape recorded, and a written confirmation will be
provided for all purchase, exchange and redemption transactions initiated by
telephone. By exchanging shares by telephone, you are acknowledging prior
receipt of a prospectus for the fund into which your shares are being exchanged.

Telephone Redemption--Check to Your Address of Record
        The Telephone Redemption feature is a quick and easy method to redeem
shares. You or your investment dealer of record can have redemption proceeds of
$50,000 or less mailed to you at your address of record. Checks will be payable
to the shareholder(s) of record. Payment is normally mailed the next business
day after receipt of the redemption request. This service is only available to
individual, joint and individual fiduciary-type accounts.

Telephone Redemption--Proceeds to Your Bank
        Redemption proceeds of $1,000 or more can be transferred to your
predesignated bank account by wire or by check. You should authorize this
service when you open your account. If you change your predesignated bank
account, you must complete an Authorization Form and have your signature
guaranteed. For your protection, your authorization must be on file. If you
request a wire, your funds will normally be sent the next business day. If the
proceeds are wired to the shareholder's account at a bank which is not a member
of the Federal Reserve System, there could be a delay in the crediting of the
funds to the shareholder's bank account. A bank wire fee may be deducted from
Fund Class redemption proceeds. If you ask for a check, it will normally be
mailed the next business day after receipt of your redemption request to your
predesignated bank account. There are no separate fees for this redemption
method, but the mail time may delay getting funds into your bank account. Simply
call the Shareholder Service Center prior to the time the offering price and net
asset value are determined, as noted above.

Telephone Exchange
        The Telephone Exchange feature is a convenient and efficient way to
adjust your investment holdings as your liquidity requirements and investment
objectives change. You or your investment dealer of record can exchange your
shares into other funds in Delaware Investments under the same registration,
subject to the same conditions and limitations as other exchanges noted above.
As with the written exchange service, telephone exchanges are subject to the
requirements of each fund, as described above and in the Prospectuses. Telephone
exchanges may be subject to limitations as to amounts or frequency.

                                                                              68
<PAGE>

        The telephone exchange privilege is intended as a convenience to
shareholders and is not intended to be a vehicle to speculate on short-term
swings in the securities market through frequent transactions in and out of the
funds in the Delaware Investments family. Telephone exchanges may be subject to
limitations as to amounts or frequency. The Transfer Agent and each Fund reserve
the right to record exchange instructions received by telephone and to reject
exchange requests at any time in the future.

MoneyLine(SM) On Demand
        You or your investment dealer may request redemptions of your Fund
shares by phone using MoneyLine(SM) On Demand. When you authorize a Fund to
accept such requests from you or your investment dealer, funds will be deposited
to (for share redemptions) your predesignated bank account. Your request will be
processed the same day if you call prior to 4 p.m., Eastern time. There is a $25
minimum and $50,000 maximum limit for MoneyLine(SM) On Demand transactions. See
MoneyLine(SM) On Demand under Investment Plans.



                                                                              69
<PAGE>

Timing Accounts
        Right to Refuse Timing Accounts--With regard to accounts that are
administered by market timing services ("Timing Firms") to purchase or redeem
shares based on changing economic and market conditions ("Timing Accounts"), the
Funds will refuse any new timing arrangements, as well as any new purchases (as
opposed to exchanges) in Delaware Investments funds from Timing Firms. A Fund
reserves the right to temporarily or permanently terminate the exchange
privilege or reject any specific purchase order for any person whose
transactions seem to follow a timing pattern who: (i) makes an exchange request
out of the Fund within two weeks of an earlier exchange request out of the Fund,
or (ii) makes more than two exchanges out of the Fund per calendar quarter, or
(iii) exchanges shares equal in value to at least $5 million, or more than 1/4
of 1% of the Fund's net assets. Accounts under common ownership or control,
including accounts administered so as to redeem or purchase shares based upon
certain predetermined market indicators, will be aggregated for purposes of the
exchange limits.

        Redemptions of Timing Accounts--Redemption requests made from Timing
Accounts will be made only by check. Redemption proceeds from these accounts
will not be wired to shareholder bank accounts. Such checks will be sent no
later than seven days after receipt of a redemption request in good order.

        Restrictions on Timed Exchanges--Timing Accounts operating under
existing timing agreements may only execute exchanges between the following
eight Delaware Investments funds: (1) Delaware Decatur Equity Income Fund, (2)
Delaware Growth and Income Fund, (3) Delaware Balanced Fund, (4) Delaware
Limited-Term Government Fund, (5) Delaware Tax-Free USA Fund, (6) Delaware Cash
Reserve Fund, (7) Delaware Delchester Fund and (8) Delaware Tax-Free
Pennsylvania Fund. No other Delaware Investments funds are available for timed
exchanges. Assets redeemed or exchanged out of Timing Accounts in Delaware
Investments funds not listed above may not be reinvested back into that Timing
Account. Each Fund reserves the right to apply these same restrictions to the
account(s) of any person whose transactions seem to follow a time pattern (as
described above).

         Each Fund also reserves the right to refuse the purchase side of an
exchange request by any Timing Account, person, or group 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. A shareholder's purchase exchanges may be restricted or refused if a
Fund receives or anticipates simultaneous orders affecting significant portions
of the Fund's assets. In particular, a pattern of exchanges that coincide with a
"market timing" strategy may be disruptive to a Fund and therefore may be
refused.

         Except as noted above, only shareholders and their authorized brokers
of record will be permitted to make exchanges or redemptions.

Systematic Withdrawal Plans
         Shareholders of Class A Shares, Class B Shares and Class C Shares who
own or purchase $5,000 or more of shares at the offering price, or net asset
value, as applicable, for which certificates have not been issued may establish
a Systematic Withdrawal Plan for monthly withdrawals of $25 or more, or
quarterly withdrawals of $75 or more, although a Fund does not recommend any
specific amount of withdrawal. This is particularly useful to shareholders
living on fixed incomes, since it can provide them with a stable supplemental
amount. This $5,000 minimum does not apply for the Fund's prototype retirement
plans. Shares purchased with the initial investment and through reinvestment of
cash dividends and realized securities profits distributions will be credited to
the shareholder's account and sufficient full and fractional shares will be
redeemed at the net asset value calculated on the third business day preceding
the mailing date.

                                                                              70
<PAGE>

         Checks are dated either the 1st or the 15th of the month, as selected
by the shareholder (unless such date falls on a holiday or a weekend), and are
normally mailed within two business days. Both ordinary income dividends and
realized securities profits distributions will be automatically reinvested in
additional shares of the Class at net asset value. This plan is not recommended
for all investors and should be started only after careful consideration of its
operation and effect upon the investor's savings and investment program. To the
extent that withdrawal payments from the plan exceed any dividends and/or
realized securities profits distributions paid on shares held under the plan,
the withdrawal payments will represent a return of capital, and the share
balance may in time be depleted, particularly in a declining market.
Shareholders should not purchase additional shares while participating in a
Systematic Withdrawal Plan.

         The sale of shares for withdrawal payments constitutes a taxable event
and a shareholder may incur a capital gain or loss for federal income tax
purposes. This gain or loss may be long-term or short-term depending on the
holding period for the specific shares liquidated. Premature withdrawals from
retirement plans may have adverse tax consequences.

         Withdrawals under this plan made concurrently with the purchases of
additional shares may be disadvantageous to the shareholder. Purchases of Class
A Shares through a periodic investment program in a Fund managed by the Manager
must be terminated before a Systematic Withdrawal Plan with respect to such
shares can take effect, except if the shareholder is a participant in one of our
retirement plans or is investing in Delaware Investments funds which do not
carry a sales charge. Redemptions of Class A Shares pursuant to a Systematic
Withdrawal Plan may be subject to a Limited CDSC if the purchase was made at net
asset value and a dealer's commission has been paid on that purchase. The
applicable Limited CDSC for Class A Shares and CDSC 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. Whether a waiver of the contingent deferred
sales charge is available or not, the first shares to be redeemed for each
Systematic Withdrawal Plan payment will be those not subject to a contingent
deferred sales charge because they have either satisfied the required holding
period or were acquired through the reinvestment of distributions. See Waiver of
Contingent Deferred Sales Charges, below.

         An investor wishing to start a Systematic Withdrawal Plan must complete
an authorization form. If the recipient of Systematic Withdrawal Plan payments
is other than the registered shareholder, the shareholder's signature on this
authorization must be guaranteed. Each signature guarantee must be supplied by
an eligible guarantor institution. Each Fund reserves the right to reject a
signature guarantee supplied by an eligible institution based on its
creditworthiness. This plan may be terminated by the shareholder or the Transfer
Agent at any time by giving written notice.

         Systematic Withdrawal Plan payments are normally made by check. In the
alternative, you may elect to have your payments transferred from your Fund
account to your predesignated bank account through the MoneyLine (SM) Direct
Deposit Service. Your funds will normally be credited to your bank account up to
four business days after the payment date. There are no separate fees for this
redemption method. It may take up to four business days for the transactions to
be completed. You can initiate this service by completing an Account Services
form. If your name and address are not identical to the name and address on your
Fund account, you must have your signature guaranteed. The Funds do not charge a
fee for any this service; however, your bank may charge a fee. This service is
not available for retirement plans.

                                                                              71
<PAGE>
         The Systematic Withdrawal Plan is not available for the Institutional
Classes. Shareholders should consult with their financial advisers to determine
whether a Systematic Withdrawal Plan would be suitable for them.

Contingent Deferred Sales Charge for Certain Redemptions of Class A Shares
Purchased at Net Asset Value
         For purchases of $1,000,000 or more made on or after July 1, 1998, a
Limited CDSC will be imposed on certain redemptions of Class A Shares (or shares
into which such Class A Shares are exchanged) according to the following
schedule: (1) 1.00% if shares are redeemed during the first year after the
purchase; and (2) 0.50% if such shares are redeemed during the second year after
the purchase, if such purchases were made at net asset value and triggered the
payment by the Distributor of the dealer's commission described above.

         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 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.

         Redemptions of such Class A Shares held for more than two years will
not be subjected to the Limited CDSC and an exchange of such Class A Shares into
another Delaware Investments fund will not trigger the imposition of the Limited
CDSC at the time of such exchange. The period a shareholder owns shares into
which Class A Shares are exchanged will count towards satisfying the two-year
holding period. The Limited CDSC is assessed if such two year period is not
satisfied irrespective of whether the redemption triggering its payment is of
Class A Shares of a Fund or Class A 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. The Limited CDSC will not be
imposed upon shares representing reinvested dividends or capital gains
distributions, or upon amounts representing share appreciation. All investments
made during a calendar month, regardless of what day of the month the investment
occurred, will age one month on the last day of that month and each subsequent
month.

account is less than the then-effective minimum account size; (ii) returns of
excess contributions to an IRA, SIMPLE IRA, 403(b)(7) or 457 Deferred
Compensation Plan, Profit Sharing Plan, Money Purchase Pension Plan, or 401(k)
Defined Contribution plan; (iii) periodic distributions from a 403(b)(7) or 457

                                      * * *

         In addition, the CDSC will be waived on Class A Shares, Class B Shares
and Class C Shares redeemed in accordance with a Systematic Withdrawal Plan if
the annual amount selected to be withdrawn under the Plan does not exceed 12% of
the value of the account on the date that the Systematic Withdrawal Plan was
established or modified.

                                                                              73

DIVIDENDS AND REALIZED SECURITIES PROFITS DISTRIBUTIONS

         Dividends, if any, are declared each day the Delaware Corporate Bond
Fund and Delaware Extended Duration Bond Fund are open and paid monthly. Net
investment income earned on days when the respective Fund is not open will be
declared as a dividend on the next business day. Dividends, if any, for the
Delaware Delchester Fund, Delaware High-Yield Opportunities Fund and Delaware
Strategic Income Fund are declared and paid monthly. Capital gains, if any, are
paid twice a year.

         Purchases of shares of the respective Fund by wire begin earning
dividends when converted into Federal Funds and are available for investment,
normally the next business day after receipt. However, if the respective Fund is
given prior notice of Federal Funds wire and an acceptable written guarantee of
timely receipt from an investor satisfying the Fund's credit policies, the
purchase will start earning dividends on the date the wire is received.
Investors desiring to guarantee wire payments must have an acceptable financial
condition and credit history in the sole discretion of the respective Fund.
Income Funds reserves the right to terminate this option at any time. Purchases
by check earn dividends upon conversion to Federal Funds, normally one business
day after receipt.

         Each Class of shares of a Fund will share proportionately in the
investment income and expenses of that Fund, except that Class A Shares, Class B
Shares and Class C Shares alone will incur distribution fees under their
respective 12b-1 Plans.

         Dividends and any realized securities profits distributions are
automatically reinvested in additional shares of the same Class of the
respective Fund at net asset value, unless, in the case of shareholders of the
Fund Classes, an election to receive dividends in cash has been made. Payment by
check of cash dividends will ordinarily be mailed within three business days
after the payable date. Dividend payments of $1.00 or less will be automatically
reinvested, notwithstanding a shareholder's election to receive dividends in
cash. If such a shareholder's dividends increase to greater than $1.00, the
shareholder would have to file a new election in order to begin receiving
dividends in cash again. If a shareholder redeems an entire account, all
dividends accrued to the time of the withdrawal will be paid by separate check
at the end of that particular monthly dividend period, consistent with the
payment and mailing schedule described above. Any check in payment of dividends
or other distributions which cannot be delivered by the United States Post
Office or which remains uncashed for a period of more than one year may be
reinvested in the shareholder's account at the then-current net asset value and
the dividend option may be changed from cash to reinvest. A Fund may deduct from
a shareholder's account the costs of the Fund's effort to locate a shareholder
if a shareholder's mail is returned by the United States Post Office or the Fund
is otherwise unable to locate the shareholder or verify the shareholder's
mailing address. These costs may include a percentage of the account when a
search company charges a percentage fee in exchange for their location services.

         If you elect to take your dividends and distributions in cash and such
dividends and distributions are in an amount of $25 or more, you may choose the
MoneyLine (SM) Direct Deposit Service and have such payments transferred from
your Fund account to your predesignated bank account. This service is not
available for certain retirement plans. It may take up to four business days for
the transactions to be completed. You can initiate either service by completing
an Account Services form. If your name and address on your designated bank
account are not identical to the name and address on your Fund account, you must
have your signature guaranteed. The Funds do not charge a fee for any MoneyLine
(SM) Service; however, your bank may charge a fee. Please call the Shareholder
Service Center for additional information about these services.



                                                                              74
<PAGE>

         Any distributions from net realized securities profits will be made
twice a year. The first payment would be made during the first quarter of the
next fiscal year. The second payment would be made near the end of the calendar
year to comply with certain requirements of the Code. Such distributions will be
reinvested in shares, unless the shareholders of the Fund Classes elect to
receive them in cash. The Funds will mail a quarterly statement showing the
dividends paid and all the transactions made during the period.

TAXES

         It is each Fund's policy to pay out substantially all net investment
income and net realized gains to relieve each Fund of federal income tax
liability on that portion of its income paid to shareholders under Subchapter M
of the Code. The Funds intend to meet the requirements each year. The Funds also
intend to meet the calendar year distribution requirements imposed by the Code
to avoid the imposition of a 4% excise tax.

         The Funds have no fixed policy with regard to distributions of realized
securities profits when such realized securities profits may be offset by
capital losses carried forward. Presently, however, the Funds intend to offset
realized securities profits to the extent of the capital losses carried forward.
Each Fund had an accumulated capital loss carryforward of the amounts listed
below at July 31, 2000 which for federal income tax purposes may be carried
forward and applied against future capital gains.

--------------------------------------------------- ---------------------
Delaware Strategic Income Fund                      $4,111,328
--------------------------------------------------- ---------------------

Delaware Corporate Bond Fund's capital loss carryforward expires as follows:
2008--$1,704,753. Delaware Delchester Fund's capital loss carryforward expires
as follows: 2002--$3,628,131, 2003--$87,593,579 and 2007--$10,982,838 and
2008--$147,703,776. Delaware Extended Duration Bond Fund's capital carryforward
expires as follows: 2008--$2,232,330. Delaware High-Yield Opportunities Fund's
capital loss carryforward expires as follows: 2007--$65,503 and
2008--$1,004,433. Delaware Strategic Income Fund's capital carryforward expires
as follows: 208--$4,11,328.

         Distributions of net investment income and short-term realized
securities profits are taxable as ordinary income to shareholders. Since the
major portion of Delaware Corporate Bond Fund's, Delaware Delchester, Delaware
Extended Duration Bond Fund's and Delaware High-Yield Opportunities Fund's
investment income is derived from interest rather than dividends, no portion of
such distributions will be eligible for the dividends-received deduction
available to corporations. It is expected that either none or a nominal portion
of Delaware Strategic Income Fund's dividends will be eligible for the
dividends-received deduction. Distributions of long-term capital gains, if any,
are taxable as long-term capital gains, for federal income tax purposes,
regardless of the length of time an investor has held such shares, and these
gains are currently taxed at long-term capital gain rates. The tax status of
dividends and distributions paid to shareholders will not be affected by whether
they are paid in cash or in additional shares. Long-term capital gains
distributions are not eligible for the dividends-received exclusion. Advice as
to the tax status of each year's dividends and distributions, when paid, will be
mailed annually. Shares of the Funds are exempt from Pennsylvania county
personal property taxes.



                                                                              75
<PAGE>

         Net long-term gain from the sale of securities when realized and
distributed (actually or constructively) is taxable as capital gain. If the net
asset value of shares were reduced below a shareholder's cost by distribution of
gain realized on sale of securities, such distribution would be a return of
investment though taxable as stated above. Each Fund's portfolio securities had
an unrealized net depreciation for tax purposes as follows as of July 31, 2000.

         Under the Taxpayer Relief Act of 1997 (the "1997 Act"), as revised by
the Internal Revenue Service Restructuring and Reform Act of 1998 (the "1998
Act") and the Omnibus Consolidated and Emergency Supplemental Appropriations
Act, a Fund is required to track its sales of portfolio securities and to report
its capital gain distributions to you according to the following categories:

         "Long-term capital gains": gains on securities sold after December 31,
         1997 and held for more than 12 months as capital assets in the hands of
         the holders are taxed at the 20% rate when distributed to shareholders
         (10% for individual investors in the 15% bracket).

         "Short-term capital gains": gains on securities sold by a Fund that do
         not meet the long-term holding period are considered short-term capital
         gains and are taxed as ordinary income.

         "Qualified 5-year gains": For individuals in the 15% bracket, qualified
         five-year gains are net gains on securities held for more than 5 years
         which are sold after December 31, 2000. For individuals who are subject
         to tax at higher rate brackets, qualified five-year gains are net gains
         on securities which are purchased after December 31, 2000 and are held
         for more than five years. Taxpayers subject to tax at a higher rate
         brackets may also make an election for shares held on January 1, 2001
         to recognize gain on their shares in order to qualify such shares as
         qualified five-year property. These gains will be taxable to individual
         investors at a maximum rate of 18% for investors in the 28% or higher
         federal income tax brackets, and at a maximum rate of 8% for investors
         in the 15% federal income tax bracket when sold after the five-year
         holding period.

         Any loss incurred on the redemption or exchange of shares held for six
months or less will be disallowed to the extent of any exempt-interest dividends
distributed to you with respect to your Fund shares and any remaining loss will
be treated as a long-term capital loss to the extent of any long-term capital
gains distributed to you by the Fund on those shares.

         All or a portion of any loss that you realize upon the redemption of
your Fund shares will be disallowed to the extent that you buy other shares in
the Fund (through reinvestment of dividends or otherwise) within 30 days before
or after your share redemption. Any loss disallowed under these rules will be
added to your tax basis in the new shares you buy.


                                                                              76
<PAGE>

         If you redeem some or all of yours shares in a Fund, and then reinvest
the sales proceeds in such Fund or in another Delaware Investments fund within
90 days of buying the original shares, the sales charge that would otherwise
apply to your reinvestment may be reduced or eliminated. The IRS will require
you to report gain or loss on the redemption of your original shares in a Fund.
In doing so, all or a portion of the sales charge that you paid for your
original shares in a Fund will be excluded from your tax basis in the shares
sold (for the purpose of determining gain or loss upon the sale of such shares).
The portion of the sales charge excluded will equal the amount that the sales
charge is reduced on your reinvestment. Any portion of the sales charge excluded
from your tax basis in the shares sold will be added to the tax basis of the
shares you acquire from your reinvestment.

       Shareholders will be notified annually by Income Funds as to the federal
income tax status of dividends and distributions paid by the Fund.

       The automatic conversion of Class B Shares into Class A Shares at the end
of approximately eight years after purchase will be tax-free for federal tax
purposes.



                                                                              77

INVESTMENT MANAGEMENT AGREEMENT AND SUB-ADVISORY AGREEMENT


         The Manager, located at One Commerce Square, Philadelphia, PA 19103,
furnishes investment management services to each Fund, subject to the
supervision and direction of the Board of Trustees of Income Funds.

         The Manager and its predecessors have been managing the funds in the
Delaware Investments family since 1938. On July 31, 2000, the Manager and its
affiliates within Delaware Investments, including Delaware International
Advisers Ltd., were managing in the aggregate more than $44 billion in assets in
the various institutional or separately managed (approximately $25,199,290,000)
and investment company ($19,329,060,000) accounts.

         The Investment Management Agreement for the Funds is dated September
29, 1999 and was approved by the initial shareholder on that date. The Agreement
provides for an initial term of two years and may be renewed each year only so
long as such renewal and continuance are specifically approved at least annually
by the Board of Trustees or by vote of a majority of the outstanding voting
securities of the Fund to which the Agreement relates, and only if the terms and
the renewal thereof have been approved by the vote of a majority of the trustees
of Income Funds or by the Manager. The Agreement will terminate automatically in
the event of its assignment.

The management fee rate schedule for each Fund is as follows:

         The Manager has entered into a Sub-Advisory Agreement with Delaware
International Advisers Ltd. (the "Sub-Adviser") on behalf of Delaware Strategic
Income Fund. Subject to the overall supervision of the Manager, the Sub-Adviser
manages the international sector of Delaware Strategic Income Fund's portfolio
and furnishes the Manager with investment recommendations, asset allocation
advice, research and other investment services with respect to foreign
securities. For the services provided to the Manager, the Manager pays the
Sub-Adviser a fee equal to one-third of the investment management fees paid to
the Manager under the terms of the Investment Management Agreement. For the
fiscal years ended July 31, 1999 and 2000, no fees were paid to the Sub-Adviser
as a result of the waiver of fees by the Manager.

         Under the general supervision of the Board of Trustees, the Manager
makes all investment decisions which are implemented by the Funds. The Manager
pays the salaries of all trustees, officers and employees of each Fund who are
affiliated with the Manager. Each Fund pays all of its other expenses, including
its proportionate share of rent and certain other administrative expenses. The
Manager is a series of Delaware Management Business Trust. The Manager changed
its form of organization from a corporation to a business trust on March 1,
1998.

         The Distributor, Delaware Distributors, L.P. (which formerly conducted
business as Delaware Distributors, Inc.), located at 1818 Market Street,
Philadelphia, PA 19103, serves as the national distributor for the Funds under
Distribution Agreements dated September 29, 1999. The Distributor is an
affiliate of the Manager and bears all of the costs of promotion and
distribution, except for payments by each Fund on behalf of the Class A Shares,

Distributors, Inc. ("DDI") is the corporate general partner of Delaware
Distributors, L.P. and both DDI and Delaware Distributors, L.P. are indirect,
wholly owned subsidiaries of Delaware Management Holdings, Inc.

         The Transfer Agent, Delaware Service Company, Inc., another affiliate
of the Manager located at 1818 Market Street, Philadelphia, PA 19103, serves as
each Fund's shareholder servicing, dividend disbursing and transfer agent
pursuant to an agreement dated September 29, 1999. The Transfer Agent also
provides accounting services to each Fund pursuant to the terms of a separate
Fund Accounting Agreement. The Transfer Agent is also an indirect, wholly owned
subsidiary of Delaware Management Holdings, Inc.

         The Funds have authorized one or more brokers to accept on their behalf
purchase and redemption orders in addition to the Transfer Agent. Such brokers
are authorized to designate other intermediaries to accept purchase and
redemption orders on the behalf of the Funds. For purposes of pricing, the Funds
will be deemed to have received a purchase or redemption order when an
authorized broker or, if applicable, a broker's authorized designee, accepts the
order. Investors may be charged a fee effecting transactions through a broker or
agent.

(1)      Under the terms of the Delaware Group Retirement Plan for
         Trustees/Directors, each disinterested trustee/director who, at the
         time of his or her retirement from the Board, has attained the age of
         70 and served on the Board for at least five continuous years, is
         entitled to receive payments from each investment company in the
         Delaware Investments family for which he or she serves as a trustee or
         director for a period equal to the lesser of the number of years that
         such person served as a trustee or director or the remainder of such
         person's life. The amount of such payments will be equal, on an annual
         basis, to the amount of the annual retainer that is paid to
         trustees/directors of each investment company at the time of such
         person's retirement. If an eligible trustee/director retired as of July
         31, 2000, he or she would be entitled to annual payments totaling the
         amounts noted above, in the aggregate, from all of the investment
         companies in the Delaware Investments family for which he or she serves
         as a trustee or director, based on the number of investment companies
         in the Delaware Investments family as of that date.
(2)      Each independent trustee/director currently receives a total annual
         retainer fee of $38,000 for serving as a trustee/director for all 33
         investment companies in Delaware Investments, plus $3,143 for each
         Board Meeting attended. Prior to May 1, 2000, John H. Durham served as
         a trustee/director for 19 Delaware Investments funds and as such
         received a total annual retainer fee of $32,180, plus $1,810 for each
         Board Meeting attended. Ann R. Leven, Charles E. Peck, Anthony D. Knerr
         and Thomas F. Madison serve on Income Funds' audit committee; Ms. Leven
         is the chairperson. Members of the audit committee currently receive
         additional annual compensation of $5,000 from all investment companies,
         in the aggregate, with the exception of the chairperson, who receives
         $6,000.

GENERAL INFORMATION

         The Trust is an open-end management investment company. Each Fund's
portfolio of assets is diversified as defined by the 1940 Act. Income Funds was
originally organized as a Delaware corporation in 1970. It was subsequently
reorganized as a Maryland corporation on March 4, 1983 and as a Delaware
business trust on September 29, 1999.

         The Manager is the investment manager of Income Funds. The Manager also
provides investment management services to certain of the other funds in the
Delaware Investments family. An affiliate of the Manager also manages private
investment accounts. While investment decisions of the Funds are made
independently from those of the other funds and accounts, investment decisions
for such other funds and accounts may be made at the same time as investment
decisions for the Funds.

         The Manager and its affiliate Delaware International Advisers Ltd.,
manage the investment options for Delaware-Lincoln ChoicePlus and Delaware
Medallion (SM) III Variable Annuities. ChoicePlus is issued and distributed by
Lincoln National Life Insurance Company. ChoicePlus offers a variety of
different investment styles managed by leading money managers. Medallion is
issued by Allmerica Financial Life Insurance and Annuity Company (First
Allmerica Financial Life Insurance Company in New York and Hawaii). Delaware
Medallion offers various investment series ranging from domestic equity funds,
international equity and bond funds and domestic fixed income funds. Each
investment series available through ChoicePlus and Medallion utilizes an
investment strategy and discipline the same as or similar to one of the Delaware
Investments mutual funds available outside the annuity, although actual
performance will differ due to such factors as different expense levels, asset
size and its timing of purchases and redemptions. See Delaware Group Premium
Fund, in Appendix B.

       The Delaware Investments Family of Funds, the Manager, the Sub-Adviser
and the Distributor, in compliance with SEC Rule 17j-1 under the 1940 Act, have
adopted Codes of Ethics which govern personal securities transactions. Under the
Codes of Ethics, persons subject to the Codes are permitted to engage in
personal securities transactions, including securities that may be purchased or
held by the Portfolios, subject to the requirements set forth in Rule 17j-1 and
certain other procedures set forth in the applicable Code of Ethics. The Codes
of Ethics for the Delaware Investments Family of Funds, the Manager, the
Sub-Adviser and the Distributor are on public file with, and are available from,
the SEC.


       The Distributor acts as national distributor for the Funds and for the
other mutual funds in the Delaware Investments family. The Distributor received
net commissions from each Fund on behalf of Class A Shares, after reallowances
to dealers, as follows:

         The Transfer Agent, an affiliate of the Manager, acts as shareholder
servicing, dividend disbursing and transfer agent for the Funds and for the
other mutual funds in the Delaware Investments family. The Transfer Agent is
paid a fee by the Funds for providing these services consisting of an annual per
account charge of $11.00 plus transaction charges for particular services
according to a schedule. Compensation is fixed each year and approved by the
Board of Trustees, including a majority of the unaffiliated trustees. The
Transfer Agent also provides accounting services to the Funds. Those services
include performing all functions related to calculating a Fund's net asset value
and providing all financial reporting services, regulatory compliance testing
and other related accounting services. For its services, the Transfer Agent is
paid a fee based on total assets of all funds in the Delaware Investments family
for which it provides such accounting services. Such fee is equal to 0.25%
multiplied by the total amount of assets in the complex for which the Transfer
Agent furnishes accounting services, where such aggregate complex assets are $10
billion or less, and 0.20% of assets if such aggregate complex assets exceed $10
billion. The fees are charged to each fund, including the Funds, on an aggregate
pro-rata basis. The asset-based fee payable to the Transfer Agent is subject to
a minimum fee calculated by determining the total number of investment
portfolios and associated classes.


         The Manager and its affiliates own the name "Delaware Group." Under
certain circumstances, including the termination of the Trust's advisory
relationship with the Manager or its distribution relationship with the
Distributor, the Manager and its affiliates could cause Income Funds to delete
the words "Delaware Group" from a Fund's name.


         The Chase Manhattan Bank ("Chase"), 4 Chase Metrotech Center, Brooklyn,
NY 11245 is custodian of each Fund's securities and cash. As custodian for a
Fund, Chase maintains a separate account or accounts for the Fund; receives,
holds and releases portfolio securities on account of the Fund; receives and
disburses money on behalf of the Fund; and collects and receives income and
other payments and distributions on account of the Fund's portfolio securities.

                                                                             101

Capitalization
      Income Funds has an unlimited authorized number of shares of beneficial
interest with no par value allocated to each Class. Each fund offers four
classes of shares, each representing a proportionate interest in the assets of
that Fund, and each having the same voting and other rights and preferences as
the other classes, except that shares of a Fund's Institutional Class may not
vote on matters affecting that Fund's Distribution Plans under Rule 12b-1.
Similarly, as a general matter, shareholders of Class A Shares, Class B Shares
and Class C Shares of a fund may vote only on matters affecting the 12b-1 Plan
that relates to the class of shares that they hold. However, Class B Shares of a
fund may vote on any proposal to increase materially the fees to be paid by the
Fund under the Rule 12b-1 Plans relating to its Class A Shares. General expenses
of a fund will be allocated on a pro-rata basis to the classes according to
asset size, except that expenses of the Rule 12b-1 Plans of each Fund's Class A,
Class B and Class C Shares will be allocated solely to those classes.


      All shares have no preemptive rights, are fully transferable and, when
issued, are fully paid and nonassessable and, except as described above, have
equal voting rights.

      Until September 30, 1996, Income Funds operated as Delaware Group
Delchester High-Yield Bond Fund, Inc., and offered one series of shares, the
Delchester Fund series. Beginning September 30, 1996, Income Funds offered
Strategic Income Fund series, beginning December 27, 1996 offered the Delaware
High-Yield Opportunities Fund series and beginning September 14, 1998 offered
Delaware Corporate Bond Fund series and Delaware Extended Duration Bond Fund
series. Beginning August 16, 1999, Delchester Fund changed its name and its
classes' names to Delaware Delchester Fund; Strategic Income Fund changed its
name and its classes' names to Delaware Strategic Income Fund; High-Yield
Opportunities Fund changed its name and its classes' names to Delaware
High-Yield Opportunities Fund; Corporate Bond Fund changed its name and its
classes' names to Delaware Corporate Bond Fund; and Extended Duration Bond Fund
changed its name and its classes' names to Delaware Extended Duration Bond Fund.
Effective as of September 29, 1999, Delaware Group Income Funds, Inc. changed
its name to Delaware Group Income Funds.

Noncumulative Voting
         Income Funds' shares have noncumulative voting rights which means that
the holders of more than 50% of the shares of Income Funds voting for the
election of trustees can elect all the trustees if they choose to do so, and, in
such event, the holders of the remaining shares will not be able to elect any
trustees.

Service, Inc.
                                Aa             High quality; together with Aaa bonds, they compose the high-grade bond group.

                                               and principal appear adequate for the present, but certain protective elements
                                               may be lacking or may be unreliable over any great length of time.

                                Ba             More uncertain with speculative elements. Protective of interest and principal
                                               payments not well safeguarded in good and bad times.

                                B              Lack characteristics of desirable investment; potentially low assurance of
                                               timely interest and principal payments or maintenance of other contract terms
                                               over time.

                                Caa            Poor standing, may be in default; elements of danger with respect to principal
                                               or interest payments.

                                Ca             Speculative in high degree; could be in default or have other marked
                                               shortcomings.

                                C              Lowest rated. Extremely poor prospects of ever attaining investment standing.


Standard & Poor's               AAA            Highest rating; extremely strong capacity to pay principal and
                                               interest.

                                AA             High quality; very strong capacity to pay principal and interest.

                                A              Strong capacity to pay principal and interest; somewhat more susceptible to
                                               the adverse effects of changing circumstances and economic conditions.

                                BBB            Adequate capacity to pay principal and interest; normally exhibit adequate
                                               protection parameters, but adverse economic conditions or changing circumstances
                                               more likely to lead to weakened capacity to pay principal and interest than for
                                               higher-rated bonds.

                                BB, B,         Predominantly speculative with respect to the issuer's capacity to meet required
                                               interest and principal payments. BB-lowest degree of speculation; CC-the highest
                                CCC, CC        degree of speculation. Quality and protective characteristics outweighed by
                                               large uncertainties or major risk exposure to adverse conditions.

                                               economic conditions and circumstances than higher-rated bonds.
                                BBB            Satisfactory credit quality; obligor's ability to pay interest and repay
                                               principal is considered adequate. Unfavorable changes in economic conditions and
                                               circumstances are more likely to adversely affect these bonds and impair timely
                                               payment. The likelihood that the ratings of these bonds will fall below
                                               investment grade is higher than for higher-rated bonds.

Earnings and Dividend Rankings for Common Stocks
             Standard & Poor's. The investment process involves assessment of
various factors -- such as product and industry position, corporate resources
and financial policy -- with results that make some common stocks more highly
esteemed than others. In this assessment, S&P believes that earnings and
dividend performance is the end result of the interplay of these factors and
that, over the long run, the record of this performance has a considerable
bearing on relative quality. The rankings, however, do not pretend to reflect
all of the factors, tangible or intangible, that bear on stock quality.

             Relative quality of bonds or other debt, that is, degrees of
protection for principal and interest, called creditworthiness, cannot be
applied to common stocks, and therefore rankings are not to be confused with
bond quality ratings which are arrived at by a necessarily different approach.

             Growth and stability of earnings and dividends are deemed key
elements in establishing Standard & Poor's earnings and dividend rankings for
common stocks, which are designed to capsulize the nature of this record in a
single symbol. It should be noted, however, that the process also takes into
consideration certain adjustments and modifications deemed desirable in
establishing such rankings.

             The point of departure in arriving at these rankings is a
computerized scoring system based on per-share earnings and dividend records of
the most recent ten years -- a period deemed long enough to measure significant
time segments of secular growth, to capture indications of basic change in trend
as they develop, and to encompass the full peak-to-peak range of the business
cycle. Basic scores are computed for earnings and dividends, then adjusted as
indicated by a set of predetermined modifiers for growth, stability within
long-term trend, and cyclicality. Adjusted scores for earnings and dividends are
then combined to yield a final score.

             Further, the ranking system makes allowance for the fact that, in
general, corporate size imparts certain recognized advantages from an investment
standpoint. Conversely, minimum size limits (in terms of corporate sales volume)
are set for the various rankings, but the system provides for making exceptions
where the score reflects an outstanding earnings-dividend record.

             The final score for each stock is measured against a scoring matrix
determined by analysis of the scores of a large and representative sample of
stocks. The range of scores in the array of this sample has been aligned with
the following ladder of rankings:
<TABLE>

              A+       Highest                    B+     Average                  C    Lowest
              A        High                       B      Below Average            D    In Reorganization
              A-       Above Average              B-     Lower
</TABLE>
          NR signifies no ranking because of insufficient data or because the
stock is not amenable to the ranking process.

          The positions as determined above may be modified in some instances by
special considerations, such as natural disasters, massive strikes, and
non-recurring accounting adjustments.

          A ranking is not a forecast of future market price performance, but is
basically an appraisal of past performance of earnings and dividends, and
relative current standing. These rankings must not be used as market
recommendations; a high-score stock may at times be so overpriced as to justify
its sale, while a low-score stock may be attractively priced for purchase.
Rankings based upon earnings and dividend records are no substitute for complete
analysis. They cannot take into account potential effects of management changes,
internal company policies not yet fully reflected in the earnings and dividend
record, public relations standing, recent competitive shifts, and a host of
other factors that may be relevant to investment status and decision.

Preferred Stock Rating
Moody's Investors Service,   Aaa        Considered to be a top-quality preferred stock.  This rating indicates good asset
Inc.                                    protection and the least risk of dividend impairment within the universe of
                                        preferred stocks.
                             Aa         Considered a high-grade preferred stock. This rating indicates that there is reasonable
                                        assurance that earnings and asset protection will remain relatively well maintained in
                                        the foreseeable future.
                             A          Considered to be an upper-medium grade preferred stock. While risks are judged to be
                                        somewhat greater than in the "aaa" and "aa" classifications, earnings and asset
                                        protection are, nevertheless, expected to be maintained at adequate levels.
                             Baa        Considered to be medium-grade, neither highly protected nor poorly secured. Earnings
                                        and asset protection appear adequate at present but may be questionable over any great
                                        length of time.
                             Ba         Considered to have speculative elements and its future cannot be considered well
                                        assured. Earnings and asset protection may be very moderate and not well safeguarded
                                        during adverse periods. Uncertainty of position characterizes preferred stocks in this
                                        class.
                             B          Generally lacks the characteristics of a desirable investment. Assurance of dividend
                                        payments and maintenance of other terms of the issue over any long period of time may
                                        be small.
                             Caa        Likely to be in arrears on dividend payments. This rating designation does not purport
                                        to indicate the future status of payments.
                             Ca         Speculative in a high degree and is likely to be in arrears on dividends with little
                                        likelihood of eventual payment.
                             C          The lowest rated class of preferred or preference stock. Issues so rated can be
                                        regarded as having extremely poor prospects of ever attaining any real investment
                                        standing.

Standard & Poor's            AAA        Has the highest rating that may be assigned by S&P to a preferred stock issue and
                                        indicates an extremely strong capacity to pay the preferred stock obligations.
                             AA         Qualifies as a high-quality fixed income security. The capacity to pay preferred stock
                                        obligations is very strong, although not as overwhelming as for issues rated "AAA".
                             A          Backed by a sound capacity to pay the preferred stock obligations, although it is
                                        somewhat more susceptible to the adverse effects of changes in circumstances and
                                        economic conditions.
                             BBB        Regarded as backed by an adequate capacity to pay the preferred stock obligations.
                                        Whereas it normally exhibits adequate protection parameters, adverse economic
                                        conditions or changing circumstances are more likely to lead to a weakened capacity to
                                        make payments for a preferred stock in this category than for issues in the "A"
                                        category.
                             BB,B,      Regarded, on balance, as predominantly speculative with respect to the issuer's
                             CCC        capacity to pay preferred stock obligations. "BB" indicates the lowest degree of
                                        speculation and "CCC" the highest degree of speculation. While such issues will likely
                                        have some quality and protective characteristics, these are outweighed by large
                                        uncertainties or major risk exposures to adverse conditions.
                             CC         Reserved for a preferred stock issue in arrears on dividends or sinking fund payments
                                        but that is currently paying.
                             C          A non-paying issue.
                             D          A  non-paying issue with the issuer in default on debt instruments.
                             NR         Indicates that no rating has been requested, that there is insufficient information on
                                        which to base a rating, or that S&P does not rate a particular type of obligation as a
                                        matter of policy.
