Profile: Aggressive Growth Fund

What are the Fund's goals?
Aggressive Growth Fund seeks long-term capital appreciation which the Fund
attempts to achieve by investing primarily in equity securities of companies we
believe have the potential for high earnings growth. Although the Fund will
strive to meet its goals, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in common stocks of companies that we believe have the
potential for high earnings growth based on our analysis of their historic or
projected earnings growth rate, price-to-earnings ratio and cash flows. We
consider companies of any size, as long as they are larger than $300 million in
market capitalization. We look for companies that are undervalued, but still
have the potential for high earnings growth.


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 by declines in stock prices.
The Fund may be subject to greater investment risk than assumed by other funds
because the companies the Fund invests in are subject to greater changes in
earnings and business prospects than companies with more established earnings
patterns. 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 with long-term financial goals.
o    Investors seeking an investment primarily in common stocks.
o    Investors seeking exposure to capital appreciation opportunities across a
     broad range of industry sectors and company sizes.

Who should not invest in the Fund
o    Investors with short-term financial goals.
o    Investors whose primary goal is current income.
o    Investors who are unwilling to accept share prices that may fluctuate,
     sometimes significantly over the short term.

How has Aggressive Growth 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 four calendar years, as well as the average annual returns of all shares
for the one-year period and since inception. The Fund's past performance is not
necessarily an indication of how it will perform in the future. The returns
reflect voluntary expense caps in effect during the periods.
The returns would be lower without the voluntary caps.

[GRAPHIC OMITTED: BAR CHART SHOWING YEAR BY YEAR TOTAL RETURN (CLASS A)]

24.06%         28.55%       48.08%       36.46%
- --------------------------------------------------------


The Fund's Class A shares had a 22.89% year-to-date return as of June 30, 1999.
During the periods illustrated in this bar chart, Class A's highest quarterly
return was 35.87% for the quarter ended September 30, 1997 and its lowest
quarterly return was -14.27% for the quarter ended September 30, 1998.

The maximum Class A sales charge of 5.75%, which is normally deducted when you
purchase shares, is not reflected in the total returns above. 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.

The Fund's returns are compared to the performance of the S&P 500 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 the securities.

*    If redeemed at end of period shown. If shares were not redeemed, the
     returns for Class B would be 35.40% and 40.16%, respectively, for the
     one-year and lifetime periods. Returns for Class C would be 35.46% and
     27.57%, respectively, for the one-year and lifetime periods.
**   The S&P 500 Index return shown is for the Class A lifetime period. The S&P
     500 Index returns for Class B and Class C lifetime periods were 28.96% and
     26.73%, respectively. 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 certain redemptions. Additional Class A purchase options that
         involve a contingent deferred sales charge may be permitted from time
         to time and will be disclosed in the prospectus if they are available.
(2)      If you redeem Class B shares during the first year after you buy them,
         you will pay a contingent deferred sales charge of 5%, which declines
         to 4% during the second year, 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 management fee has been restated to reflect a new management fee
         which became effective on April 1, 1999.
(5)      The investment manager has contracted to waive fees and pay expenses
         through June 30, 2000 in order to prevent total operating expenses
         (excluding any 12b-1 expenses, taxes, interest, brokerage fees and
         extraordinary expenses) from exceeding 1.50% 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. 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: Growth Stock Fund

What are the Fund's goals?
Growth Stock Fund seeks long-term capital appreciation through investment in
equity securities diversified among individual companies and industries.
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 common stocks that we believe have the potential for
long-term capital appreciation. Our strategy is to identify large,
well-established growth companies with a track record of consistent earnings and
dividend increases.


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 price of Fund shares will increase and
decrease according to changes in the value of the Fund's investments. This Fund
will be affected by declines in stock prices, which can be caused by a decline
in the stock market or poor performance from specific companies that can result
from negative earnings reports or dividend reductions. For a more complete

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

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 with long-term financial goals.
o   Investors looking for capital growth potential.
o   Investors looking for a fund that can be a complement to income-producing
    or value-oriented investments.

Who should not invest in the Fund
o   Investors with short-term financial goals.
o   Investors who are unwilling to accept share prices that may fluctuate,
    sometimes significantly, over the short term.
o   Investors whose primary goal is to receive current income.

How has Growth Stock 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 ten calendar years, as well as the average annual returns of all shares for
the one-, five- and ten-year periods. The Fund's past performance is not
necessarily an indication of how it will perform in the future. The returns
reflect voluntary expense caps. The returns would be lower without the voluntary
caps.

The Fund's Class A shares had a 6.61% year-to-date return as of June 30, 1999.
During the periods illustrated in this bar chart, Class A's highest quarterly
return was 22.33% for the quarter ended March 31, 1991 and its lowest quarterly
return was -22.22% for the quarter ended September 30, 1990.

The maximum Class A sales charge of 5.75%, which is normally deducted when you
purchase shares, is not reflected in the total returns above. If this fee were
included, the returns would be less than those shown. The average annual returns
in the table shown on page __ do include the sales charge.

The Fund's returns are compared to the performance of the S&P 500 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 the securities.

     returns for Class B would be 11.93% and 20.76%, respectively, for the
     one-year and lifetime periods. Returns for Class C would be 11.97% and
     20.01%, respectively, for the one-year and lifetime periods.

**   Lifetime returns are shown if the Fund or Class existed for less than ten
     years. The S&P 500 Index return shown is for ten years. The Index returns
     for Class B and Class C lifetime periods were 28.05% and 29.03%,
     respectively. Maximum sales charges are included in the Fund returns in the

(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. Additional Class A purchase options that
         involve a contingent deferred sales charge may be permitted from time
         to time and will be disclosed in the prospectus if they are available.
(2)      If you redeem Class B shares during the first year after you buy them,
         you will pay a contingent deferred sales charge of 5%, which declines
         to 4% during the second year, 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 management fee has been restated to reflect a new management fee
         which became effective on April 1, 1999.
(5)      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.
(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

Our investment strategies
We research individual companies and analyze economic and market conditions,
seeking to identify the securities or market sectors that we think are the best
investments for the Funds. Following is a description of how the portfolio
managers pursue each Fund's investment goal.

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

Aggressive Growth Fund
For the Aggressive Growth Fund, we strive to identify companies that offer the
potential for long-term price appreciation because they are likely to experience
high earnings growth. The companies we choose for the portfolio typically
exhibit one or more of the following characteristics:

o   A history of high growth in earnings-per-share
o   Projections for high future growth or acceleration in earnings-per-share
o   A price-to-earnings ratio that is low relative to other stocks
o   Discounted cash flows that are high relative to other stocks

Once we identify stocks that have these characteristics, we further evaluate the
company. We look at the capability of the management team, the strength of the
company's position within its industry, whether its internal structure can
support continued growth, how high the company's return on equity is, how much
of the company's profits are reinvested into the company to fuel additional
growth, and how stringent the company's financial and accounting policies are.

All of these give us insight into the outlook for the company, helping us to
identify companies poised for high earnings growth. We believe that this high
earnings growth, if it occurs, would result in price appreciation for the
company's stock.

We maintain a well-diversified portfolio, typically holding a mix of different
stocks, representing a wide array of industries and a mix of small companies,
medium-size companies and large companies.

Growth Stock Fund
The Growth Stock Fund seeks long-term capital appreciation. Our strategy for the
Fund is to invest at least 80% of the Fund's assets in common stock.

We primarily consider companies whose earnings and dividend records have
received either an A+ or A rating (the two highest ratings) from Standard &
Poor's, a nationally recognized statistical ratings organization. From the list
of stocks that have received this rating, we typically select 20 to 30 companies
for the portfolio. We evaluate the following factors:

o   Potential increased demand for the company's products or services
o   Development of new or improved products or services
o   Probability of increased operating efficiency
o   Positive changes in management
o   Emphasis on research and development
o   Likelihood of mergers or acquisitions
o   The company's opportunities relative to cyclical economic conditions and
o   Whether the stock appears temporarily undervalued

Growth Stock Fund follows a long-term approach to investing. As long as the
outlook for the company remains favorable, we generally hold stocks for long
periods, striving to capture the full capital appreciation potential.

portfolio in the annual or semi-annual shareholder report.

Lending securities
Each Fund may lend up to 25% of its assets to qualified dealers and investors
for their use in security transactions.

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.

Borrowing from banks
Each Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions, though the Funds normally do not do so. Aggressive
Growth Fund will not purchase new securities if borrowing exceeds 5% of net
assets.

Portfolio turnover
We anticipate that Aggressive Growth 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 the
Fund. We anticipate that Growth Stock Fund's annual turnover will be less than
100%.

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. The following are the chief
risks you assume when investing in Aggressive Growth Fund or Growth Stock Fund.
Please see the Statement of Additional Information for further discussion of
these risks and the other risks not discussed here.

Board of directors A mutual fund is governed by a board of directors which has
oversight responsibility for the management of the fund's business affairs.
Directors 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 directors must be independent of the fund's
investment manager or distributor. These independent fund directors, 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. They 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 typically place them with a qualified bank custodian who
segregates fund securities from other bank assets.

                                       16
<PAGE>

Distributor Most mutual funds continuously offer new shares to the public
through distributors who are regulated as broker-dealers and are subject to
National Association of Securities Dealers, Inc. (NASD) 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 directors. 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 5.75% 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 $50,000 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
     0.25% 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.

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

     buy them.

o    If you redeem Class B shares during the first year after you buy them, the
     shares will be subject to a contingent deferred sales charge of 5%. The
     contingent deferred sales charge is 4% during the second year, 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 0.25%.
     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 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.

How to buy shares

[GRAPHIC OMITTED: ILLUSTRATION OF A PERSON]

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

[GRAPHIC OMITTED: ILLUSTRATION OF AN ENVELOPE]

By mail
Complete an investment slip and mail it with your check, made payable to the
fund and class of shares you wish to purchase, to Delaware Investments, 1818
Market Street, Philadelphia, PA 19103-3682. If you are making an initial
purchase by mail, you must include a completed investment application (or an
appropriate retirement plan application if you are opening a retirement account)
with your check.

[GRAPHIC OMITTED: ILLUSTRATION OF A JAGGED LINE]

By wire
Ask your bank to wire the amount you want to invest to First Union Bank, ABA
#031201467, Bank Account number 2014 12893 4013. Include your account number and
the name of the fund in which you want to invest. If you are making an initial
purchase by wire, you must call us so we can assign you an account number.

[GRAPHIC OMITTED: ILLUSTRATION OF AN EXCHANGE SYMBOL]

By exchange
You can exchange all or part of your investment in one or more funds in the
Delaware Investments family for shares of other funds in the family. Please keep
in mind, however, that under most circumstances you are allowed to exchange only
between like classes of shares. To open an account by exchange, call the
Shareholder Service Center at 800.523.1918.

[GRAPHIC OMITTED: ILLUSTRATION OF A KEYPAD]

Through automated shareholder services
You can purchase or exchange shares through Delaphone, our automated telephone
service, or through our web site, www.delawareinvestments.com. For more
information about how to sign up for these services, call our Shareholder
Service Center at 800.523.1918.

Once you have completed an application, you can open an account with an initial
investment of $1,000--and make additional investments at any time for as little
as $100. 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.

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 receive your order before the close of 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 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 determine each Fund's net asset value (NAV) per share at the close of 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 directors. Any fixed-income securities that have a
maturity of less than 60 days we price at amortized cost. We price all other
securities at their fair market value using a method approved by the board of
directors.

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.

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 $50,000 or
more, 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, the First Union Bank fee (currently
$7.50) will 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 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 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.

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 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 sales charge and without
paying 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 similar 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 CDSC
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.

About your account (continued)

Special services (continued)

MoneyLineSM 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 paid annually. Capital gains, if any, are paid at least
annually, however, additional payments may be made to comply with tax
requirements applicable to the Funds. 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 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.
Distributions declared in October, November or December but paid in January are
taxable as if they were paid in December.

Certain management considerations

Year 2000
As with other mutual funds, financial and business organizations and individuals
around the world, the Funds could be adversely affected if the computer systems
used by their service providers do not properly process and calculate
date-related information from and after January 1, 2000. This is commonly known
as the "Year 2000 Problem." Each Fund is taking steps to obtain satisfactory
assurances that its major service providers are taking steps reasonably designed
to address the Year 2000 Problem on the computer systems that the service
providers use. However, there can be no assurance that these steps will be
sufficient to avoid any adverse impact on the business of the Funds. The
portfolio managers and investment professionals of each Fund consider Year 2000
issues in the securities selection and investment process. However, there can be
no guarantee that, even with their due diligence efforts, they will be able to
predict the effect of Year 2000 on any company or the performance of its
securities.

Investments by Fund of Funds
Aggressive Growth Fund accepts investments from the series portfolios of
Delaware Group Foundation Funds, a fund of funds. From time to time, the 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, the Fund may be required to sell securities
or invest cash at times when it would not otherwise do so. These transactions
could also have tax consequences if sales of securities result in gains, and
could also increase transactions costs or portfolio turnover. The manager will
monitor transactions by Foundation Funds and will attempt to minimize any
adverse effects on the Fund and Foundation Funds as a result of these
transactions.

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 report, along with the Funds' financial statements, is included in the
Funds' annual report, which is available upon request by calling 800.523.1918.
The information for the fiscal periods ending on or before April 30, 1997 has
been audited by the Funds' previous independent auditors.

How to read the Financial highlights

Net investment income
Net investment income includes dividend and interest income earned from the
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 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 the 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 the 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 rate
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.

How to use this 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.

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.

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.

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.

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.

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

Profile: Aggressive Growth Fund

What are the Fund's goals?
Aggressive Growth Fund seeks long-term capital appreciation which the Fund
attempts to achieve by investing primarily in equity securities of companies we
believe have the potential for high earnings growth. Although the Fund will
strive to meet its goals, there is no assurance that it will.

What are the Fund's main investment strategies?
We invest primarily in common stocks of companies that we believe have the
potential for high earnings growth based on our analysis of their historic or
projected earnings growth rate, price-to-earnings ratio and cash flows. We
consider companies of any size, as long as they are larger than $300 million in
market capitalization. We look for companies that are undervalued, but still
have the potential for high earnings growth.


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 by declines in stock prices.
The Fund may be subject to greater investment risk than assumed by other funds
because the companies the Fund invests in are subject to greater changes in
earnings and business prospects than companies with more established earnings
patterns. 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 with long-term financial goals.
o Investors seeking an investment primarily in common stocks.
o Investors seeking exposure to capital appreciation opportunities across a
  broad range of industry sectors and company sizes.

Who should not invest in the Fund
o Investors with short-term financial goals.
o Investors whose primary goal is current income.
o Investors who are unwilling to accept share prices that may fluctuate,
  sometimes significantly over the short term.

How has Aggressive Growth 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 four calendar years, as well as the average annual returns of
these shares for the one-year period and since inception. Aggressive Growth
Fund's Institutional Class commenced operations on August 29, 1997. Return
information for the Class for the periods prior to the time the Class commenced
operations is calculated by taking the performance of Aggressive Growth Fund A
Class and eliminating all sales charges that apply to Class A shares. However,
for those periods, Class A 12b-1 payments were not eliminated, and performance
would have been affected if this adjustment had been made. The Fund's past
performance is not necessarily an indication of how it will perform in the
future. The returns reflect voluntary expense caps in effect during the periods.
The returns would be lower without the voluntary caps.

The Fund's Institutional Class shares had a 23.04% year-to-date return as of
June 30, 1999. During the periods illustrated in this bar chart, Institutional
Class' highest quarterly return was 36.08% for the quarter ended September 30,
1997 and its lowest quarterly return was -14.23% for the quarter ended March 31,
1997.

The Fund's returns are compared to the performance of the S&P 500 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 the securities.

Profile: Growth Stock Fund

What are the Fund's goals?
Growth Stock Fund seeks long-term capital appreciation through investment in
equity securities diversified among individual companies and industries.
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 common stocks that we believe have the potential for
long-term capital appreciation. Our strategy is to identify large,
well-established growth companies with a track record of consistent earnings and
dividend increases.

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 price of Fund shares will increase and
decrease according to changes in the value of the Fund's investments. This Fund
will be affected by declines in stock prices, which can be caused by a decline
in the stock market or poor performance from specific companies that can result
from negative earnings reports or dividend reductions. 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 with long-term financial goals.
o Investors looking for capital growth potential.
o Investors looking for a fund that can be a complement to income-producing or
  value-oriented investments.

Who should not invest in the Fund
o Investors with short-term financial goals.
o Investors who are unwilling to accept share prices that may fluctuate,
  sometimes significantly, over the short term.
o Investors whose primary goal is to receive current income.

How has Growth Stock 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 of these
shares for the one-, five- and ten-year periods. Growth Stock Fund's
Institutional Class commenced operations on August 29, 1997. Return information
for the Class for the periods prior to the time the Class commenced operations
is calculated by taking the performance of Growth Stock Fund A Class and
eliminating all sales charges that apply to Class A shares. However, for those
periods, Class A 12b-1 payments were not eliminated, and performance would have
been affected if this adjustment had been made. The Fund's past performance is
not necessarily an indication of how it will perform in the future. The returns
reflect voluntary expense caps in effect during the periods. The returns would
be lower without the voluntary caps.

How we manage the Funds

Our investment strategies
We research individual companies and analyze economic and market conditions,
seeking to identify the securities or market sectors that we think are the best
investments for the Funds. Following is a description of how the portfolio
managers pursue each Fund's investment goal.

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

Aggressive Growth Fund
For the Aggressive Growth Fund, we strive to identify companies that offer the
potential for long-term price appreciation because they are likely to experience
high earnings growth. The companies we choose for the portfolio typically
exhibit one or more of the following characteristics:

o a history of high growth in earnings-per-share;
o projections for high future growth or acceleration in earnings-per-share;
o a price-to-earnings ratio that is low relative to other stocks; or
o discounted cash flows that are high relative to other stocks.

Once we identify stocks that have these characteristics, we further evaluate the
company. We look at the capability of the management team, the strength of the
company's position within its industry, whether its internal structure can
support continued growth, how high the company's return on equity is, how much
of the company's profits are reinvested into the company to fuel additional
growth, and how stringent the company's financial and accounting policies are.

All of these give us insight into the outlook for the company, helping us to
identify companies poised for high earnings growth. We believe that this high
earnings growth, if it occurs, would result in price appreciation for the
company's stock.

We maintain a well-diversified portfolio, typically holding a mix of different
stocks, representing a wide array of industries and a mix of small companies,
medium-size companies and large companies.

Growth Stock Fund
The Growth Stock Fund seeks long-term capital appreciation. Our strategy for the
Fund is to invest at least 80% of the Fund's assets in common stock.

We primarily consider companies whose earnings and dividend records have
received either an A+ or A rating (the two highest ratings) from Standard &
Poor's, a nationally recognized statistical ratings organization. From the list
of stocks that have received this rating, we typically select 20 to 30 companies
for the portfolio. We evaluate the following factors:

o potential increased demand for the company's products or services;
o development of new or improved products or services;
o probability of increased operating efficiency;
o positive changes in management;
o emphasis on research and development;
o likelihood of mergers or acquisitions;
o the company's opportunities relative to cyclical economic conditions; and
o whether the stock appears temporarily undervalued.

Growth Stock Fund follows a long-term approach to investing. As long as the
outlook for the company remains favorable, we generally hold stocks for long
periods, striving to capture the full capital appreciation potential.

Aggressive Growth Fund may also invest in other securities including preferred
stocks, convertible securities, warrants, rights, futures, options, debt
securities of government or corporate issuers or investment company securities.
Growth Stock Fund may also invest in preferred stock, debt securities of
government or corporate issuers and investment company securities. Both Funds
may invest up to 10% of net assets in foreign securities including American
Depositary Receipts and Global Depositary Receipts; however, the managers have
no present intention of doing so.

Please see the Statement of Additional Information for additional descriptions
and risk information on these securities as well as those listed in the table
above. You can find additional information about the investments in a Fund's
portfolio in the annual or semi-annual shareholder report.

Lending securities
Each Fund may lend up to 25% of its assets to qualified dealers and investors
for their use in security transactions.

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.

Borrowing from banks
Each Fund may borrow money as a temporary measure for extraordinary purposes or
to facilitate redemptions, though the Funds normally do not do so. Aggressive
Growth Fund will not purchase new securities if borrowing exceeds 5% of net
assets.

Portfolio turnover
We anticipate that Aggressive Growth 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 the
Fund. We anticipate that Growth Stock Fund's annual turnover will be less than
100%.

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. The following are the chief
risks you assume when investing in Aggressive Growth Fund or Growth Stock Fund.

                                  Shareholders

Board of directors A mutual fund is governed by a board of directors which has
oversight responsibility for the management of the fund's business affairs.
Directors 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 directors must be independent of the fund's
investment manager or distributor. These independent fund directors, 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. They 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 typically 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
National Association of Securities Dealers, Inc. (NASD) 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 directors. 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 receive your order before the close of 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 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 determine each Fund's net asset value (NAV) per share at the close of 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 directors. Any fixed-income securities that have a
maturity of less than 60 days we price at amortized cost. We price all other
securities at their fair market value using a method approved by the board of
directors.

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 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 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 paid annually. Capital gains, if any, are paid at least
annually, however, additional payments may be made to comply with tax
requirements applicable to the Funds. 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 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.
Distributions declared in October, November or December but paid in January are
taxable as if they were paid in December.

Certain management considerations

Year 2000
As with other mutual funds, financial and business organizations and individuals
around the world, the Funds could be adversely affected if the computer systems
used by their service providers do not properly process and calculate
date-related information from and after January 1, 2000. This is commonly known
as the "Year 2000 Problem." Each Fund is taking steps to obtain satisfactory
assurances that its major service providers are taking steps reasonably designed
to address the Year 2000 Problem on the computer systems that the service
providers use. However, there can be no assurance that these steps will be
sufficient to avoid any adverse impact on the business of the Funds. The
portfolio managers and investment professionals of each Fund consider Year 2000
issues in the securities selection and investment process. However, there can be
no guarantee that, even with their due diligence efforts, they will be able to
predict the effect of Year 2000 on any company or the performance of its
securities.

Investments by Fund of Funds
Aggressive Growth Fund accepts investments from the series portfolios of
Delaware Group Foundation Funds, a fund of funds. From time to time, the 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, the Fund may be required to sell securities
or invest cash at times when it would not otherwise do so. These transactions
could also have tax consequences if sales of securities result in gains, and
could also increase transactions costs or portfolio turnover. The manager will
monitor transactions by Foundation Funds and will attempt to minimize any
adverse effects on the Fund and Foundation Funds as a result of these
transactions.

Net investment income
Net investment income includes dividend and interest income earned from the
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 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 the 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 the 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 rate
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.

Profile: Tax-Efficient Equity Fund

What are the Fund's goals?
Tax-Efficient Equity Fund seeks to obtain for taxable investors a high total
return on an after-tax basis. 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 common stocks. We strive to manage the portfolio so that
we minimize dividend income and defer the realization of accrued capital gains.
Our goal with this strategy is to minimize distributions that would be taxable
for shareholders.

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 price of Fund shares will increase and
decrease according to changes in the value of the Fund's investments. This Fund
will be particularly affected by changes in stock prices, which tend to
fluctuate more than bond prices. Stock prices may be negatively affected by
declines in the stock market or poor performance in specific industries or
companies. For a more complete discussion of risk, please turn to 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 in high tax brackets.
o Investors with long-term financial goals such as retirement or education
  financing.
o Investors seeking an investment primarily in common stocks.

Who should not invest in the Fund
o Investors with short-term financial goals.
o Investors who are unwilling to accept share prices that may fluctuate,
  sometimes significantly over the short term.
o Investors whose assets are tax-exempt or tax-deferred, including assets
  in an IRA or a qualified retirement plan.

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.

How has Tax-Efficient Equity 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 calendar year,
as well as the average annual returns of all shares for the one-year period and
since inception. The Fund's past performance is not necessarily an indication of
how it will perform in the future. The returns reflect voluntary expense caps in
effect during the periods. The returns would be lower without the voluntary
caps.

The Fund's Class A shares had a -1.56% year-to-date return as of June 30, 1999.
During the period illustrated in this bar chart, Class A's highest quarterly
return was 22.81% for the quarter ended December 31, 1998 and its lowest
quarterly return was -11.36% for the quarter ended September 30, 1998.


The maximum Class A sales charge of 5.75%, which is normally deducted when you
purchase shares, is not reflected in the total returns above. 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.

The Fund's returns are compared to the performance of the S&P 500 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 the securities.

         who is paid a commission, a contingent deferred sales charge will apply
         to certain redemptions. Additional Class A purchase options that

How we manage the Fund

Our investment strategies
We research individual companies and analyze economic and market conditions,
seeking to identify the securities or market sectors that we think are the best
investments for Tax-Efficient Equity Fund. Following are descriptions of how the
portfolio manager pursues the Fund's investment goals.

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

Tax-Efficient Equity Fund
Tax-Efficient Equity Fund invests the majority of its assets in common stocks.
This Fund uses a tax-efficient management strategy, with a goal of providing a
high after-tax total return for investors with assets that are subject to
current taxes.


We invest primarily in common stocks that we believe have the potential for
price appreciation over time. Under normal conditions, at least 65% of the
Fund's assets will be in equity securities (like common stocks and securities
convertible into common stocks). Generally, at least 85% of the Fund's assets
will be in a mix of common stocks, securities that are convertible into common
stocks or in instruments whose returns depend on common stock prices.


Stock selection strategy
In selecting stocks for Tax-Efficient Equity Fund, we consider factors such as:
o whether the stock appears overvalued or undervalued based on its
  price/earnings ratio compared to other stocks in the market;
o how stable the company's earnings growth has been in the past;
o the company's potential for strong positive cash flow;
o the potential for positive fundamental changes in the company's business; and,
o whether there is appreciation potential that results from the company
  being misunderstood or under-researched by Wall Street analysts.

Tax management strategy
Most mutual funds buy and sell securities throughout the year and consequently
accumulate realized capital gains. Typically, these gains are distributed to
shareholders at the end of the year. If your mutual fund account is not
tax-exempt or tax-deferred, you have to pay current taxes on those gains. As a
result of taxable distributions, the after-tax return on your taxable
investments may be substantially lower than your pre-tax return.


We employ investment strategies that aim to minimize taxable distributions for
shareholders. Though some realization of capital gains will probably be
inevitable in connection with sales of securities in the Fund's portfolio, our
goal is to minimize gains or postpone them as long as possible. Shareholders may
be subject to taxes when they sell shares of the Fund if the values of the
shares have increased; however, by seeking to minimize taxable distributions, we
give shareholders more control of when they will incur taxes. Our strategies
include:


o focusing on common stocks with low or no dividend yields so as to minimize
  distributions of dividend income;
o keeping portfolio turnover low to avoid realizing capital gains;
o harvesting tax losses; that is, selling stocks with unrealized losses in order
  to cancel out realized gains from other stocks;
o selling shares that qualify for long-term capital gains treatment first when
  we decide to sell a stock that has appreciated;
o selling shares that have the highest cost basis first so as to minimize
  realized gains when we decide to sell a stock that has appreciated; and
o using a defensive options strategy to protect the gains on a particular stock
  from an anticipated decline in the stock market or the individual stock
  without actually selling that stock. (For more information on this strategy,
  please see "The securities we invest in" on page ___.)

Board of directors A mutual fund is governed by a board of directors which has
oversight responsibility for the management of the fund's business affairs.
Directors 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 directors must be independent of the fund's
investment manager or distributor. These independent fund directors, 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 typically 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
National Association of Securities Dealers, Inc. (NASD) 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.

                                       11

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 directors. 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 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 5.75% 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 $50,000 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 above.

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 year after you buy them, the
  shares will be subject to a contingent deferred sales charge of 5%. The
  contingent deferred sales charge is 4% during the second year, 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
  no more than 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 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.

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 receive your order before the close of 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 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 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 directors. Any fixed-income securities that have a
maturity of less than 60 days we price at amortized cost. We price all other
securities at their fair market value using a method approved by the board of
directors.

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 this 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.

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 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 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.

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 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 sales charge and without
paying 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 similar 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 CDSC
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.

About your account (continued)

Special services (continued)

MoneyLineSM 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 paid annually. Capital gains, if any, are paid at least
annually, however, additional payments may be made to comply with tax
requirements applicable to the Fund. 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.
Distributions declared in October, November or December but paid in January are
taxable as if they were paid in December.

Certain management considerations

Year 2000
As with other mutual funds, financial and business organizations and individuals
around the world, the Fund could be adversely affected if the computer systems
used by its service providers do not properly process and calculate date-related
information from and after January 1, 2000. This is commonly known as the "Year
2000 Problem." The Fund is taking steps to obtain satisfactory assurances that
its major service providers are taking steps reasonably designed to address the
Year 2000 Problem on the computer systems that the service providers use.
However, there can be no assurance that these steps will be sufficient to avoid
any adverse impact on the business of the Fund. The portfolio managers and
investment professionals of the Fund consider Year 2000 compliance in the
securities selection and investment process. However, there can be no guarantee
that, even with their due diligence efforts, they will be able to predict the
effect of Year 2000 on any company or the performance of its securities.

How to read the Financial highlights

Net investment income
Net investment income includes dividend and interest income earned from the
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 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 the 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 the 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 rate
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.

Profile: Tax-Efficient Equity Fund

What are the Fund's goals?
Tax-Efficient Equity Fund seeks to obtain for taxable investors a high total
return on an after-tax basis. 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 common stocks. We strive to manage the portfolio so that
we minimize dividend income and defer the realization of accrued capital gains.
Our goal with this strategy is to minimize distributions that would be taxable
for shareholders.

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 price of Fund shares will increase and
decrease according to changes in the value of the Fund's investments. This Fund
will be particularly affected by changes in stock prices, which tend to
fluctuate more than bond prices. Stock prices may be negatively affected by
declines in the stock market or poor performance in specific industries or
companies. For a more complete discussion of risk, please turn to 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 in high tax brackets.
o Investors with long-term financial goals such as retirement or education
  financing.
o Investors seeking an investment primarily in common stocks.

Who should not invest in the Fund
o Investors with short-term financial goals.
o Investors who are unwilling to accept share prices that may fluctuate,
  sometimes significantly over the short term.
o Investors whose assets are tax-exempt or tax-deferred, including assets in an
  IRA or a qualified retirement plan.

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.

How has Tax-Efficient Equity Fund performed?

This bar chart and table can help you evaluate the risks of investing in the
Fund. We show returns for the Fund for the past calendar year, as well as the
average annual returns for the one-year period and since inception. Return
information for the Class is calculated by taking the performance of
Tax-Efficient Equity Fund A Class and eliminating all sales charges that apply
to Class A shares. However, Class A 12b-1 payments were not eliminated, and
performance would have been affected if this adjustment had been made. The
Fund's past performance is not necessarily an indication of how it will perform
in the future. The returns reflect voluntary expense caps in effect during the
periods. The returns would be lower without the voluntary caps.

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 the securities.

(1)      Exchanges are subject to the requirements of each fund in the Delaware
         Investments family. A front-end sales charge may apply if you exchange
         your shares into a fund that has a front-end sales charge.

(2)      The investment manager has agreed to waive fees and pay expenses
         through October 31, 1999 in order to prevent total operating expenses
         (excluding taxes, interest, brokerage fees and extraordinary expenses)
         from exceeding 1.20% of average daily net assets. The fees and expenses
         shown in the table above do not reflect this voluntary expense cap. The

How we manage the Fund

Our investment strategies
We research individual companies and analyze economic and market conditions,
seeking to identify the securities or market sectors that we think are the best
investments for Tax-Efficient Equity Fund. Following are descriptions of how the
portfolio manager pursues the Fund's investment goals.

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

Tax-Efficient Equity Fund
Tax-Efficient Equity Fund invests the majority of its assets in common stocks.
This Fund uses a tax-efficient management strategy, with a goal of providing a
high after-tax total return for investors with assets that are subject to
current taxes.


We invest primarily in common stocks that we believe have the potential for
price appreciation over time. Under normal conditions, at least 65% of the
Fund's assets will be in equity securities (like common stocks and securities
convertible into common stocks). Generally, at least 85% of the Fund's assets
will be in a mix of common stocks, securities that are convertible into common
stocks or in instruments whose returns depend on common stock prices.


Stock selection strategy
In selecting stocks for Tax-Efficient Equity Fund, we consider factors such as:
o whether the stock appears overvalued or undervalued based on its
  price/earnings ratio compared to other stocks in the market;
o how stable the company's earnings growth has been in the past;
o the company's potential for strong positive cash flow;
o the potential for positive fundamental changes in the company's business; and,
o whether there is appreciation potential that results from the company being
  misunderstood or under-researched by Wall Street analysts.

Tax management strategy
Most mutual funds buy and sell securities throughout the year and consequently
accumulate realized capital gains. Typically, these gains are distributed to
shareholders at the end of the year. If your mutual fund account is not
tax-exempt or tax-deferred, you have to pay current taxes on those gains. As a
result of taxable distributions, the after-tax return on your taxable
investments may be substantially lower than your pre-tax return.


We employ investment strategies that aim to minimize taxable distributions for
shareholders. Though some realization of capital gains will probably be
inevitable in connection with sales of securities in the Fund's portfolio, our
goal is to minimize gains or postpone them as long as possible. Shareholders may
be subject to taxes when they sell shares of the Fund if the values of the
shares have increased; however, by seeking to minimize taxable distributions, we
give shareholders more control of when they will incur taxes. Our strategies
include:


o focusing on common stocks with low or no dividend yields so as to minimize
  distributions of dividend income;
o keeping portfolio turnover low to avoid realizing capital gains;
o harvesting tax losses; that is, selling stocks with unrealized losses in order
  to cancel out realized gains from other stocks;
o selling shares that qualify for long-term capital gains treatment first when
  we decide to sell a stock that has appreciated;
o selling shares that have the highest cost basis first so as to minimize
  realized gains when we decide to sell a stock that has appreciated; and
o using a defensive options strategy to protect the gains on a particular stock
  from an anticipated decline in the stock market or the individual stock
  without actually selling that stock. (For more information on this strategy,
  please see "The securities we invest in" on page____.)

                                  Shareholders

Board of directors A mutual fund is governed by a board of directors which has
oversight responsibility for the management of the fund's business affairs.
Directors 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 directors must be independent of the fund's
investment manager or distributor. These independent fund directors, 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 typically 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
National Association of Securities Dealers, Inc. (NASD) rules governing mutual
fund sales practices.


                                       11

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 directors. 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.


Certain management considerations

Year 2000
As with other mutual funds, financial and business organizations and individuals
around the world, the Fund could be adversely affected if the computer systems
used by its service providers do not properly process and calculate date-related
information from and after January 1, 2000. This is commonly known as the "Year
2000 Problem." The Fund is taking steps to obtain satisfactory assurances that
its major service providers are taking steps reasonably designed to address the
Year 2000 Problem on the computer systems that the service providers use.
However, there can be no assurance that these steps will be sufficient to avoid
any adverse impact on the business of the Fund. The portfolio managers and
investment professionals of the Fund consider Year 2000 compliance in the

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 receive your order before the close of 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 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 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 directors. Any fixed-income securities that have a
maturity of less than 60 days we price at amortized cost. We price all other
securities at their fair market value using a method approved by the board of
directors.

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 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 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 paid annually. Capital gains, if any, are paid at least
annually, however, additional payments may be made to comply with tax
requirements applicable to the Fund. 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.
Distributions declared in October, November or December but paid in January are
taxable as if they were paid in December.

Financial highlights
The financial highlights table is intended to help you understand the 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 report, along with the Fund's financial statements, is included in the
Fund's annual report, which is available upon request by calling 800.523.1918.

For the period September 1, 1997 through March 9, 1998, the Institutional Class
sold shares which were subsequently redeemed by shareholders. As of April 30,
1999, the class had one share outstanding, representing initial seed purchase.
There was no shareholder activity during the year. Data for this Class is
excluded from the Financial highlights because the data is not believed to be
meaningful. Data shown are derived from Tax-Efficient Equity Fund A Class which
commenced operations on June 27, 1997 and reflect 12b-1 Plan expenses paid by
that class.

How to read the Financial highlights

Net investment income
Net investment income includes dividend and interest income earned from the
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 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 the 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 the 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 rate
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.
