Portfolio management review > Delaware Cash Reserve Fund April 10, 2006 Fund manager Cynthia Isom Portfolio Manager The fiscal year ended March 31, 2006, with the Federal Reserve Board raising short-term interest rates to 4.75% and reiterating its long-standing commitment to fighting inflation. Benjamin Bernanke stuck to the Federal Reserve's playbook in his first meeting as chairman, as the fed's Open Market Committee boosted borrowing costs to a five-year high and hinted that an additional interest rate increase or increases could be in store. This marked the fifteenth straight interest rate increase by the fed since June 2004. As a whole, money market funds have had a successful year, posting their first annual gains in assets since 2001. Currently, money market funds are widening their rate advantage over options such as bank saving accounts. At this time, some money market funds, which invest in short-term instruments, have attractive yields and the advantage of keeping cash in relatively safe securities, such as certificates of deposit and commercial paper. Delaware Cash Reserve Fund returned 3.11% (Class A shares at net asset value with dividends reinvested) for the fiscal year ended March 31, 2006.* The average taxable money market fund, as measured by the 393 funds that compose the Lipper Money Market Funds Average, returned 2.86% for the same period. Typical of a money market fund, more than half of the Delaware Cash Reserve Fund's assets remain invested in commercial paper, which represents obligations issued by corporations or banks to finance short-term credit needs, such as accounts receivable and inventory. Delaware Investments believes that the US economy will continue to be strong in the second quarter and grow at a moderate pace later in 2006. We remain mindful of global inflationary pressures, which we believe will continue to be an overriding concern for the U.S. economy in the near and intermediate future. High energy and commodity prices give further evidence that investors should be mindful of potential inflationary pressures. Amid this economic backdrop and fairly rich spread valuations, we expect to remain more cautious in non-Treasury sectors. Our view is that the dollar will weaken versus most trading partners' currencies in 2006 because of the growing US trade imbalance. Regardless of the near-term outlook, it remains important for investors to periodically reexamine the asset allocation within their investment portfolios. For individuals seeking stability of principal or needing to keep cash-equivalent assets handy while making decisions about stock and bond investments, we believe Delaware Cash Reserve Fund can continue to be a valuable short-term investment vehicle. * For complete annualized performance for Delaware Cash Reserve Fund, please see the table on page 2. 1 Performance summary > Delaware Cash Reserve Fund The performance data quoted represent past performance; past performance does not guarantee future results.

Current performance may be lower or higher than the performance data quoted. Please obtain the performance data for the most recent month end by calling 800 523-1918 or visiting our Web site at www.delawareinvestments.com/performance. You should consider the investment objectives, risks, charges and expenses of the investment carefully before investing. The Delaware Cash Reserve Fund prospectus contains this and other important information about the Fund. Please request a prospectus by calling 800 523-1918. Read it carefully before you invest or send money. Performance includes reinvestment of all distributions and is subject to change.

An investment in Delaware Cash Reserve Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment of $1.00 per share, it is possible to lose money by investing in Delaware Cash Reserve Fund. Returns and yields will fluctuate. Past performance is not a guarantee of future results. Class A shares are available without sales charges or any 12b-1 fees. Consultant Class shares were first made available on March 10, 1988 and are available without a sales charge. Consultant Class performance prior to March 10, 1988 for Delaware Cash Reserve Fund is based on Class A performance. Performance after March 10, 1988 reflects the impact of an annual service and distribution fee of up to 0.30%. 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. They are also subject to an annual distribution and service fee of up to 1%. Lifetime and 10-year performance figures for Class B shares reflect conversion to Consultant Class after eight years. Class C shares are sold with a contingent deferred sales charge of 1% if redeemed during the first 12 months. They are also subject to an annual distribution and service fee of up to 1%. An expense limitation was in effect for all classes of Delaware Cash Reserve Fund during all periods shown. Performance would have been lower had the expense limitation not been in effect. The performance table does not reflect the deduction of taxes the shareholder would pay on Fund dividends or redemptions of Fund shares. Delaware Cash Reserve Fund Class B and C shares are available only as part of an overall investment program using Class B or C shares of other funds. Direct investment into Delaware Cash Reserve Fund Class B or C shares may be made only when establishing a Wealth Builder plan. Performance, excluding sales charges, for Class B and C shares assumes either that contingent deferred sales charges did not apply or the investment was not redeemed. 2 Fund Basics As of March 31, 2006 - -------------------------------------------------------------------------------- Fund objective - -------------------------------------------------------------------------------- The Fund seeks to provide maximum current income, while preserving principal and maintaining liquidity. - -------------------------------------------------------------------------------- Total fund net assets - -------------------------------------------------------------------------------- $425.09 million - -------------------------------------------------------------------------------- Number of holdings - -------------------------------------------------------------------------------- 47 - -------------------------------------------------------------------------------- Fund start date - -------------------------------------------------------------------------------- June 30, 1978 - -------------------------------------------------------------------------------- Your fund manager - -------------------------------------------------------------------------------- Cynthia Isom joined Delaware Investments in 1985 as a trader of money market, high-grade, and Treasury securities. Prior to coming to Delaware, she worked as an institutional salesperson with Merrill Lynch. Ms. Isom holds a bachelor's degree from Vassar College. - -------------------------------------------------------------------------------- Nasdaq symbols - -------------------------------------------------------------------------------- Class A DCRXX - -------------------------------------------------------------------------------- CUSIP Numbers: - -------------------------------------------------------------------------------- Class A 245910-10-4 Class B 245910-30-2 Class C 245910-40-1 Consultant Class 245910-20-3 3 Disclosure of Fund expenses For the Period October 1, 2005 to March 31, 2006 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 October 1, 2005 to March 31, 2006. 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 assume reinvestment of all dividends and distributions. "Expenses Paid During Period" are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

See accompanying notes 13 Notes to financial statements > Delaware Cash Reserve Fund March 31, 2006 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(R) 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) for financial reporting purposes. 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 daily from net investment income 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 expense paid under the above arrangement is included in custodian fees on the Statement of Operations with the corresponding expense offset shown as "expense 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. Effective July 1, 2005, 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 0.70% of average daily net assets of the Fund, which can be revoked at any time. Prior to July 1, 2005, DMC had elected to waive its fees in order to prevent such expenses from exceeding 0.65% of the average daily net assets of the Fund. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective May 19, 2005, the Fund pays DSC a monthly fee computed at the annual rate of 0.04% of the Fund's average daily net assets for accounting and administration services. Prior to May 19, 2005, the Fund paid 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 elected to waive distribution and service fees in order to prevent these fees from exceeding 0.25% of average daily net assets for Consultant Class shares. These waivers may be revoked at any time. Prior to July 1, 2005, DDLP had elected to waive distribution and service fees in order to prevent these fees from exceeding 0.50% of average daily net assets for Class B and C shares. At March 31, 2006, the Fund had liabilities payable to affiliates as follows: Investment management fee payable to DMC $143,928 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 92,946 Distribution fee payable to DDLP 17,541 Other expenses payable to DMC and affiliates* 11,406 * 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. 14 (continued) Notes to financial statements > Delaware Cash Reserve Fund 2. Investment Management, Administration Agreements and Other Transactions with Affiliates (continued) As provided in the investment management agreement, the Fund bears the cost of certain legal services expenses, including internal legal services provided to the Fund by DMC employees. For the year ended March 31, 2006, the Delaware Cash Reserve Fund was charged $28,775 for internal legal services provided by DMC. For the year ended March 31, 2006, DDLP received gross contingent deferred sales charge commissions of $79,299 and $3,213 on redemption of the Fund's Class B and Class C shares, respectively. These commissions were entirely used to offset up-front commissions previously paid by DDLP to broker dealers on sales of those shares. 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. 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. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes.

(continued) 15 Notes to financial statements > Delaware Cash Reserve Fund 6. Contractual Obligations The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote. 7. 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 year basis for income tax purposes, which may include distributions for portions of two fiscal years of a fund.

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. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (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. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2006, by correspondence with the custodian and brokers. 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 the Delaware Cash Reserve Fund series of Delaware Group Cash Reserve at March 31, 2006, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Philadelphia, Pennsylvania May 12, 2006 17 Delaware Investments(R) Family of Funds Board of trustees/directors and officers addendum A mutual fund is governed by a Board of Trustees/Directors ("Trustees"), which has oversight responsibility for the management of a fund's business affairs.
