DISCLOSURE                    For the Period April 1, 2004 to September 30, 2004
  OF FUND EXPENSES

As a shareholder of the Fund, you incur two types of costs:
(1) transaction costs, including sales charges (loads) on purchase payments,
reinvested dividends, or other distributions; redemption fees; and exchange
fees; and (2) ongoing costs, including management fees; distribution and/or
service (12b-1) fees; and other Fund expenses. This Example is intended to help
you understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period April 1, 2004 to September 30, 2004.

ACTUAL EXPENSES
The first section of the table shown, "Actual Fund Return,"
provides information about actual account values and actual expenses. You may
use the information in this section of the table, together with the amount you
invested, to estimate the expenses that you paid over the period. Simply divide
your account value by $1,000 (for example, an $8,600 account value divided by
$1,000 = 8.6), then multiply the result by the number in the first section under
the heading entitled "Expenses Paid During Period" to estimate the expenses you
paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second section of the table shown, "Hypothetical 5% Return," provides
information about hypothetical account values and hypothetical expenses based on
the Fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the Fund's actual return. The hypothetical account
values and expenses may not be used to estimate the actual ending account
balance or expenses you paid for the period. You may use this information to
compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), redemption fees, or exchange fees. Therefore, the second
section of the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have been
higher. The Fund's actual expenses shown in the table reflect fee waivers in
effect. The expenses shown in the table below assume reinvestment of all
dividends and distributions.


In each case, "Expenses Paid During Period" are equal to the Fund's annualized
expense ratio, multiplied by the average account value over the period,
multiplied by 183/366 (to reflect the one-half year period).

(1) Effective October 1, 2004, the Fund's manager decreased contractual expense
    waivers in effect for the Fund, causing the expenses paid by the Fund to
    increase. Had the new expense waivers been in effect during the period, the
    Fund's expense analysis would be as follows:

SECTOR ALLOCATION                                       As of September 30, 2004
   DELAWARE CASH RESERVE

The SEC adopted a requirement that all funds present their categories of
portfolio holdings in a table, chart, or graph format in their annual and
semiannual shareholder reports, whether or not a schedule of investments is
utilized. The following chart lists the Fund's categories of portfolio holdings
as a percent of total net assets and is provided in compliance with such
requirement.

    reflects waivers and payment of fees by the manager and distributor, as
    applicable. Performance would have been lower had the expense limitation not
    been in effect.

NOTES                                           DELAWARE CASH RESERVE FUND
   TO FINANCIAL STATEMENTS                      September 30, 2004 (Unaudited)


Delaware Group Cash Reserve (the "Trust") is organized as a Delaware statutory
trust and offers one series, the Delaware Cash Reserve Fund (the "Fund"). The
Trust is an open-end investment company. The Fund is considered diversified
under the Investment Company Act of 1940, as amended, and offers Class A, Class
B, Class C and Consultant Class shares. Class A and Consultant Class shares are
not subject to a sales charge. Class B shares are sold with a contingent
deferred sales charge that declines from 4% to zero depending upon the period of
time the shares are held. Class B shares will automatically convert to
Consultant Class shares on a quarterly basis approximately eight years after
purchase. Class C shares are sold with a contingent deferred sales charge of 1%,
if redeemed during the first 12 months.

The investment objective of the Fund is to seek to provide maximum current
income, while preserving principal and maintaining liquidity.

1. SIGNIFICANT ACCOUNTING POLICIES

The following accounting policies are in accordance with U.S. generally accepted
accounting principles and are consistently followed by the Fund.

Security Valuation -- Securities are valued at amortized cost, which
approximates market value.

Federal Income Taxes -- The Fund intends to continue to qualify for federal
income tax purposes 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.

Class Accounting -- Investment income and common expenses are allocated to the
classes of the Fund on the basis of "settled shares" of each class in relation
to the net assets of the Fund. 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.

Use of Estimates -- The preparation of financial statements in conformity with
U.S. generally accepted accounting principles 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.
Management fees and some other expenses are paid monthly. 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. Interest income is
recorded on the accrual basis. Discounts and premiums are amortized to interest
income over the lives of the respective securities. The Fund declares dividends
from net investment income daily and pays such dividends monthly.

The Fund receives earnings credits from its custodian when positive cash
balances are maintained, which are used to offset custody fees. The earnings
credits for the period ended September 30, 2004 were approximately $1,393. 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".


2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH
   AFFILIATES
In accordance with the terms of its investment management agreement, the Fund
pays Delaware Management Company (DMC), a series of Delaware Management Business
Trust and the investment manager, an annual fee which is calculated daily at the
rate of 0.45% on the first $500 million of average daily net assets of the Fund,
0.40% on the next $500 million, 0.35% on the next $1.5 billion and 0.30% on the
average daily net assets in excess of $2.5 billion.

DMC has elected to waive that portion, if any, of its management fee and
reimburse the Fund to the extent necessary to ensure that annual operating
expenses, exclusive of taxes, interest, brokerage commissions, distribution
fees, certain insurance costs and extraordinary expenses, do not exceed 0.45% of
average daily net assets of the Fund, which can be revoked at any time.
Effective October 1, 2004, DMC has elected to waive its fees in order to prevent
annual operating expenses from exceeding 0.65% of the average daily net asset of
the Fund.

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting,
administration, dividend disbursing and transfer agent services. The Fund pays
DSC a monthly fee based on average net assets subject to certain minimums for
accounting and administration services. The Fund pays DSC a monthly fee based on
the number of shareholder accounts for dividend disbursing and transfer agent
services.

Pursuant to a distribution agreement and distribution plan, the Fund pays
Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an
annual distribution and service fee not to exceed 0.30% of the average daily net
assets of the Consultant Class shares and 1.00% of the average daily net assets
of the Class B and C shares. Class A shares pay no distribution and service
expenses. DDLP has contracted to waive distribution and service fees through May
31, 2005 in order to prevent distribution and service fees of the Consultant
Class shares from exceeding 0.25% of average daily net assets. DDLP has elected
to waive its distribution and service fees in order to prevent distribution fees
of Class B and C shares from exceeding 0.50% of the average daily net assets,
which can be revoked at any time.

At September 30, 2004, the Fund had receivables from or liabilities payable to
affiliates as follows:

  Investment management fee payable to DMC           $(57,556)
  Dividend disbursing, transfer agent,
   accounting and administration fees
   and other expenses payable to DSC                   10,511
  Other expenses payable to DMC and affiliates*       (26,777)

*DMC, as part of its administrative services, pays operating expenses on behalf
 of the Fund and is reimbursed on a periodic basis. Such expenses include items
 such as printing of shareholder reports, fees for audit, legal and tax
 services, registration fees and trustees' fees.

As provided in the investment management agreement, the Fund bears the cost of
certain legal services expenses, including in-house legal services provided to
the Fund by DMC employees. For the period ended September 30, 2004, the Fund had
costs of $0.

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

   TO FINANCIAL STATEMENTS (CONTINUED)

3. DIVIDEND AND DISTRIBUTION INFORMATION
Income distributions are determined in accordance with federal income tax
regulations, which may differ from U.S. generally accepted accounting
principles. The tax character of dividends paid during the six months ended
September 30, 2004 and the year ended March 31, 2004 was as follows:

                                                       Six Months     Year

   Ordinary income                                     $2,171,365   $3,635,949

*Tax information for the period ended September 30, 2004 is an estimate and the
 tax character of dividends may be redesignated at fiscal year end.

The components of net assets are estimated since final tax characteristics
cannot be determined until fiscal year end. As of September 30, 2004, the
estimated components of net assets on a tax basis were as follows:

   Shares of beneficial interest                                 $503,885,524
   Capital loss carryforwards                                        (348,776)

At March 31, 2004, for federal income tax purposes, the Fund had capital loss
carryforwards of $351,845, which may be carried forward and applied against
future capital gains. Such capital loss carryforwards expire as follows:

gains of $3,069, which may be offset by the capital loss carryforwards.
