Dear Shareholder


"MAJOR INDEXES SUCH
AS THE DOW JONES
INDUSTRIAL AVERAGE,
THE S&P 500, AND THE
NASDAQ COMPOSITE ARE
IN NEGATIVE TERRITORY
YEAR-TO-DATE THROUGH
OCTOBER 31, 2000."


December 4, 2000


Recap of Events -- The record-setting expansion of the U.S. economy has
continued in 2000, yet the U.S. equities market has cooled considerably after
strong performance in recent years. Volatility in the markets has been running
high, and the broad market for U.S. equities is struggling toward its most
disappointing calendar year since 1994. After strong performance in late 1999
and early 2000, stock market indexes gave up significant ground in the spring
and have been volatile ever since. Major indexes such as the Dow Jones
Industrial Average, the S&P 500, and the Nasdaq Composite are in negative
territory year-to-date through October 31, 2000.

There are several reasons for the volatility. Recently, disappointing earnings
announcements by one company have often been followed by brief, but sharp,
declines in whole sectors. The rising cost of oil has analysts concerned that
the pace of economic activity may slow, causing consumers to reduce spending,
especially for low-end retail products.

There is also concern on the part of investors and analysts over stock
valuations for companies that play roles in the New Economy. In recent months,
we've begun to see increased focus on corporate fundamentals such as earnings
and questions about the long-term sustainability of corporate growth. We believe
this trend is positive, as it has been helping to move stocks toward fair
values.

Delaware U.S. Growth Fund, by definition of its investment strategy, focuses on
earnings as a major part of its stock selection process. Your Fund invests in
growth stocks -- companies that we believe offer significant potential for
future growth. Among the stock selection criteria for the Fund are evidence of a
solid earnings track record and new ways for sustaining and growing revenues.

Your Fund returned +30.84% during the fiscal year ended October 31, 2000 (Class
A shares at net asset value with distributions reinvested), outperforming both
the Lipper Large-Cap Growth Fund Average (+15.44%) and the benchmark Standard &
Poor's 500 Index (+4.88%). This outperformance can be attributed in part to the
Fund's heavier weighting relative to its benchmark in a number of technology
stocks that saw significant appreciation during the year.

Generally, investors in growth stocks have fared quite well in recent years. A
strong U.S. economy, the growth of the Internet, and a general upswing in
old-fashioned entrepreneurialism have all contributed to what has been a fertile
landscape for growth companies during the last half-decade. Although we believe
the outlook remains bright for many growing U.S. companies, the strong
double-digit returns posted by your Fund and some of its peers over the last
year cannot be sustained. Sectors or investment styles that are performing well
today may struggle tomorrow. The strong returns achieved by the
better-performing funds in the Lipper Large-Cap Growth Funds class over the past
year, for example, often came during the first half of the period, when
conditions in the market were considerably more favorable than they have been in
recent months.

Market Outlook -- One year ago, our outlook for the U.S. stock market was for a
return to normalcy -- that is, a resumption of stock returns that are closer to
normal averages of about 11% annually. We think that the events of the past 12
months have set such a trend in motion. We also expect market volatility to
continue, but believe that your Fund is well-positioned to take advantage of
growth investment opportunities that arise in the market.

Since it is impossible to predict the short-term direction of the markets with
any real accuracy, we recommend that investors continue to rely on basic, sound
principles of investing. These include sticking to a regular investment plan,
diversifying your assets, and keeping a long-term outlook, as well as
considering your own risk tolerance and financial goals. For help in balancing
such considerations, contact your financial advisor.

On the pages that follow, Delaware U.S. Growth Fund manager Francis Houghton
discusses your Fund's performance over the past year and provides his outlook on
the equities market. As always, we thank you for remaining committed to Delaware
Investments.


Sincerely,

/s/ Wayne A. Stork                        /s/ David K. Downes

PORTFOLIO MANAGEMENT REVIEW
---------------------------

        Francis Houghton
Senior Portfolio Manager

        December 4, 2000

"THE YEAR 2000 HAS
GENERALLY BEEN
DIFFICULT FOR MANY
U.S. COMPANIES."

The Fund's Results
The year 2000 has generally been difficult for many U.S. companies. Most
publicly traded companies lost ground in the stock market since January (Source:
Bloomberg), with the Nasdaq Composite Index taking the worst hit of the major
U.S. equity indexes. As of October 31, 2000, the Nasdaq Composite has lost 17.9%
year-to-date in 2000.

For much of our fiscal year, the market was both volatile and narrow, often led
by just a few stocks. Adding to the challenge was the fact that many growth
stocks were "priced for perfection" -- that is, many investors have bought the
stock based on growth potential, after seeing analysts' forecasts of the
company's future top-line growth. The common result is a stock with future
earnings already accounted for in its market price. In such a scenario, the
stock may well be overpriced regardless of the company's financial strength or
outlook. A strong, growing company can then see its high stock price decrease
after reporting financial results that are strong, but which disappoint
investors by narrowly missing growth forecasts.

Against this backdrop, we have tried to structure Delaware U.S. Growth Fund's
portfolio to capture as much potential growth as possible while minimizing risk.

Delaware U.S. Growth Fund focuses on companies that, in our opinion, are poised
for accelerated earnings growth rates. We particularly focus on companies that
are undergoing a positive fundamental change. We look for catalysts such as:

o management changes
o the introduction of new products
o changes in the economy which favor an industry
o a corporate restructuring or turnaround

Portfolio Highlights
As of October 31, 2000, the Fund's largest sector was healthcare and
pharmaceuticals, which generally performed well during the fiscal year. We hold
a diverse collection of healthcare and pharmaceutical companies. Abbott
Laboratories, one of our top holdings in the sector, saw positive performance
during the year, as did Johnson & Johnson, a stock which we bought during the
year's second half when it started to rebound from a slump last winter. Also
performing well within this sector were medical equipment companies such as
Baxter International, a manufacturer of products and technologies related to the
blood and circulatory system, and Medtronic, the world's leading manufacturer of
pacemakers.

                                                                               3

Portfolio Characteristics

---------------------------------------------------------------------
Beta*                                                           1.05
---------------------------------------------------------------------
Average Price-to-Earnings Ratio**                              33.50
---------------------------------------------------------------------
Median Market Capitalization                          $31.37 billion
---------------------------------------------------------------------

 *Beta is a measure of risk relative to the S&P 500 Index. A number less than
  1.0 means less historical price volatility than the Index. A number higher
  than 1.0 means more historical volatility.

**P/E is based on analysts' forward earnings estimates as reported by First
  Call/Thomson Financial.


Another healthcare-related company that we think has strong growth potential is
PE Corp. -- PE Biosystems Group, which manufactures instrumentation for use in
life sciences research. The markets for PE Biosystems' products include an array
of biotech researchers, including those working in basic human disease research,
genetic analysis, and agricultural research.

The technology sector, in general, has performed poorly since March 2000, and we
slightly decreased our exposure to this sector over the second half of our
fiscal year. However, it remained the Fund's second-largest sector as of October
31, 2000. A handful of our large-cap technology holdings, including Oracle and
Cisco Systems, were down significantly over the second half despite showing net
positive performance for the full fiscal year.

Telecommunications stocks, in particular, have frequently been victims of the
market's recent volatility. Telecommunications stocks that detracted from
overall performance include Nextel Communications and Sprint, which lost nearly
two thirds of its value over the second half of our fiscal year.

Despite this, we believe in the long-term growth potential of our current
telecommunications holdings, as well as our holdings in computers and
technology. We think the outlook for many stocks in these sectors remains
bright, and that as a whole they will rebound. We do expect, however, that
future growth will often be at a slower pace than we had originally anticipated.

Our percentage of holdings in the Fund's third-largest sector, energy stocks,
increased slightly to 14.7% of the portfolio since we last reported to you at
mid-fiscal-year. While the sector generally performed well during the year as
oil prices rose, deregulation has caused uncertainty in the industry. Many
traditional utility companies have suspended plans for building and upgrading
power plants as they wait for clarification of legislation. This uncertainty has
created an excellent opportunity for non-traditional energy companies, which are
often unregulated, to fill the void and begin building their own power
facilities. We think this can eventually benefit some of the energy companies in
the Fund, such as Enron, AES Corporation, Calpine and Dynegy.

Another critical component in the energy sector is the need to provide assurance
for electrical power. The standard for electrical assurance has been raised in
recent years, as technology-dependent, modern corporations find they cannot risk
being without power for even a few seconds. Emerson Electric's line of products
and services, including software, help customers meet these new standards,
manage process control, and connect their businesses.

In the coming months we will also be monitoring the defense and financial
sectors for buying opportunities, as we believe that the potential for growth in
these sectors is quite positive.

Outlook
The economy continues to grow at what we consider to be a realistic and
sustainable rate. Although we have seen a mild slowdown this year, the U.S.
continues to enjoy a high rate of productivity that reflects increased
efficiency and which so far has muted any inflationary pressures. We think that
the investments in technology made by U.S. companies in the 1980s and early
1990s are now paying off, and believe the economy can continue to benefit from
these investments.

We see a bright future for many growth stocks, and will continue to monitor the
markets during the coming months for stocks that have been left at attractive
prices by the market's recent struggles. We hope that investors will continue to
be rewarded by their long-term investments in Delaware U.S. Growth Fund.

Returns reflect reinvestment of distributions and any applicable sales charges
as noted below. Returns and share values will fluctuate so that shares, when
redeemed, may be worth more or less than their original cost. Class B and C
share results, excluding sales charges, assume either that contingent deferred
sales charges did not apply or the investment was not redeemed.

Past performance is not a guarantee of future results.

Class A shares have a 5.75% maximum front-end sales charge and a 12b-1 fee.

Class B shares do not have a front-end sales charge, but are subject to a 1%
annual distribution and service fee. They are also subject to a contingent
deferred sales charge of up to 5% if redeemed before the end of the sixth year.

Class C shares have a 1% annual distribution and service fee. If redeemed within
12 months, a 1% contingent deferred sales charge applies.

The average annual total returns for the lifetime, five-year and one-year
periods ended October 31, 2000 for Delaware U.S. Growth Fund Institutional Class
were 20.12%, 23.71% and 31.21%, respectively. The Institutional Class was
originally made available without sales charges only to a certain eligible
institutional accounts on February 3, 1994.

An expense limitation was in effect for all classes of Delaware U.S. Growth Fund
during the periods shown. Performance would have been lower if the expense
limitation was not in effect.

Notes to Financial Statements

October 31, 2000
--------------------------------------------------------------------------------
Delaware Group Adviser Funds (the "Trust") is organized as a Delaware business
trust and offers three series: the Delaware U.S. Growth Fund, the Delaware
Overseas Equity Fund and the Delaware New Pacific Fund. These financial
statements and related notes pertain to the Delaware U.S. Growth Fund (the
"Fund"). The Fund is a diversified open-end investment company under the
Investment Company Act of 1940, as amended. The Fund offers four classes of
shares. The A Class carries a maximum front-end sales charge of 5.75%. The B
Class carries a back-end deferred sales charge. The C Class carries a level load
deferred sales charge and the Institutional Class has no sales charge.

The objective of the Fund is to seek to maximize capital appreciation.

1. Significant Accounting Policies
The following accounting policies are in accordance with accounting principles
generally accepted in the United States and are consistently followed by the
Fund.

Security Valuation - All equity securities are valued at the last quoted sales
price as of the close of the New York Stock Exchange (NYSE) on the valuation
date. If on a particular day an equity security does not trade, then the mean
between the bid and asked prices will be used. Money market instruments having
less than 60 days to maturity are valued at amortized cost, which approximates
market value. Other securities and assets for which market quotations are not
readily available are valued at fair value as determined in good faith under the
direction of the Fund's Board of Trustees.

Federal Income Taxes - The Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
the Fund on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

Repurchase Agreements - The Fund may invest in a pooled cash account along with
other members of the Delaware Investments Family of Funds. The aggregate daily
balance of the pooled cash account is invested in repurchase agreements secured
by obligations of the U.S. Government. The respective collateral is held by the
Fund's custodian bank until the maturity of the respective repurchase
agreements. Each repurchase agreement is 102% collateralized. However, in the
event of default or bankruptcy by the counterparty to the agreement, realization
of the collateral may be subject to legal proceedings.

Use of Estimates - The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

Other - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Dividend income is recorded on the ex-dividend date and interest income is
recorded on the accrual basis. The Fund declares and pays dividends from net
investment income and capital gains, if any, annually.

Certain expenses of the Fund are paid through commission arrangements with
brokers. These transactions are done subject to best execution. The amount of
these expenses was approximately $5,508 for the period ended October 31, 2000.
In addition, the Fund receives earnings credits from its custodian when positive
balances are maintained, which are used to offset custody fees. These credits
were $6,429 for the period ended October 31, 2000. The expenses paid under the
above arrangements are included in their respective expense captions on the
Statement of Operations with the corresponding expense offset shown as "Expenses
paid indirectly".
<PAGE>

2. Investment Management and Other Transactions with Affiliates
In accordance with the terms of the Investment Management Agreement, the Fund
currently pays Delaware Management Company (DMC) a series of Delaware Management
Business Trust and the Investment Manager of the Fund, an annual fee which is
calculated daily at the rate of 0.65% on the first $500 million of net assets,
0.60% on the next $500 million, 0.55% on the next $1.5 billion, and 0.50% on the
net assets in excess of $2.5 billion. At October 31, 2000, the Fund had a
liability for investment management fees and other expenses payable to DMC of
$153,347. Prior to March 1, 2000, Lynch & Mayer, Inc., an affiliate of DMC,
served as sub-adviser to the Fund, for which it received a subadvisory fee
directly from DMC. Effective March 1, 2000, management of Lynch & Mayer and
Delaware Investments integrated Lynch & Mayer's investment personnel into DMC.
As a result of the integration, Lynch & Mayer no longer serves as sub-adviser to
the Fund.

The Fund has engaged Delaware Service Company, Inc. (DSC), an affiliate of DMC,
to provide dividend disbursing, transfer agent, accounting and administration
services. The Fund pays DSC a monthly fee based on the number of shareholder
accounts, shareholder transactions, and average net assets, subject to certain
minimums. At October 31, 2000, the Fund had a liability for such fees and other
expenses payable to DSC of $123,041.

                                                                              15

Notes to Financial Statements (continued)

--------------------------------------------------------------------------------
Pursuant to the Distribution Agreement, the Fund pays Delaware Distributors,
L.P. (DDLP), the Distributor and an affiliate of DMC, an annual fee not to
exceed 0.30% of the average daily net assets of the A Class and 1.00% of the
average daily net assets of the B and C Classes. No distribution expenses are
paid by the Institutional Class. At October 31, 2000, the Fund had a liability
for distribution fees and other expenses payable to DDLP of $57,990.

For the period ended October 31, 2000, DDLP earned $69,228 for commissions on
sales of the Fund A Class shares.

Certain officers of DMC, DSC and DDLP are officers, trustees and/or employees of
the Fund. These officers, trustees and employees are paid no compensation by the
Fund.

3. Investments
For the period ended October 31, 2000, the Fund made purchases of $337,078,408
and sales of $242,804,516 of investment securities other than U.S. government
securities and temporary cash investments.

As of October 31, 2000, unrealized appreciation for federal income tax purposes
aggregated $58,859,187 of which $70,845,786 related to unrealized appreciation
of securities and $11,986,599 related to unrealized depreciation of securities.
At October 31, 2000, the aggregate cost of securities was $227,940,505.

4. Capital Shares

5. Lines of Credit
The Fund, along with certain other funds in the Delaware Investments Family of
Funds (the "Participants"), participate in a $375,400,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each fund's allocation of the entire facility. The Participants may
borrow up to a maximum of one-third of their net assets under the agreement. The
Fund had no amount outstanding as of October 31, 2000, or at any time during the
period.

6. Tax Information (Unaudited)
The information set forth below is for the Fund's fiscal year as required by
federal laws. Shareholders, however, must report distributions on a calendar
basis for income tax purposes, which may include distributions for portions of
two fiscal years of a fund. Accordingly, the information needed by shareholders
for income tax purposes will be sent to them in early 2001. Please consult your
tax advisor for proper treatment of this information.

For the fiscal year ended October 31, 2000, the Fund designates distributions
paid during the year as follows:

Report of Independent Auditors

--------------------------------------------------------------------------------
To the Shareholders and Board of Trustees
Delaware Group Adviser Funds - Delaware U.S. Growth Fund

We have audited the accompanying statement of net assets of Delaware U.S. Growth
Fund (the "Fund") as of October 31, 2000, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the four years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
period ended October 31, 1996 were audited by other auditors whose report dated
December 20, 1996 expressed an unqualified opinion on those financial
highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of October 31, 2000, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Delaware U.S. Growth Fund at October 31, 2000, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended, and its financial highlights for each of the four years
in the period then ended, in conformity with accounting principles generally
accepted in the United States.
