PORTFOLIO DELAWARE AMERICAN GOVERNMENT BOND FUND MANAGEMENT REVIEW August 8, 2005 FUND MANAGERS Steven R. Cianci Portfolio Manager Paul Grillo Portfolio Manager Q: PLEASE DESCRIBE THE NATURE OF THE FIXED INCOME MARKETS DURING THE 12-MONTH PERIOD ENDED JULY 31, 2005. A: During the last five months of 2004, interest rates steadily trended downward as evidence of economic weakness, as with soft auto and retail sales, and crude oil prices continued to rise, pressing $50 per barrel. These factors generally led market participants to lower their expectations for economic expansion. Beginning this period at 4.48%, 10-year Treasury yields dropped to a low of 3.99% after September's disappointing non-farm payroll number before rising to a year-ending 4.24%. During November, crude oil prices declined by 5% after reaching $55 per barrel in early October. Already trending downward, the U.S. dollar continued to weaken over the final three months of 2004, declining -9.0% and -7.2% versus the euro and yen, respectively (source: Bloomberg L.P.). Furthermore, the Federal Reserve Board remained committed to raising rates at "a measured pace." The fed-funds rate had risen from 1.25% at the fiscal year's start to 2.25% by calendar year-end (source: St. Louis Federal Reserve Bank). From the onset of 2005 until July 31, 10-year Treasury yields first moved downward, to a seven-month low of 3.91%, before beginning their ascent to 4.28% by fiscal year-end. During this period, a "bull flattening" trend was largely in place, with the yield spread between two- and 30-year Treasuries narrowing, given market uncertainty over U.S. economic growth prospects (source: Bloomberg L.P.). In our opinion, foreign demand, European economic slowdown, and investor perceptions of an "inflation fighting" Federal Reserve Board fueled the tendency toward relatively low long-term yields. Perhaps Federal Reserve Chairman Alan Greenspan put it best, when in attempting to describe the sense of disconnect between rising short-term rates and muted longer-term bond yield, he employed the term "conundrum" (source: Reuters Group PLC). Mid-high grade corporates, along with agency and mortgage bonds, were the top performers during the fiscal year, while asset-backed securities (ABS) and Treasury Inflation-Protected Securities (TIPS) were some of the top underperformers (source: Citigroup Global Markets Inc.). Q: HOW WELL DID THE FUND PERFORM RELATIVE TO ITS BENCHMARK AND PEER GROUP? A: Delaware American Government Bond Fund performed in line relative to its benchmark and peer group, returning +4.60% (Class A shares at net asset value with distributions reinvested) for the fiscal year ended July 31, 2005. The Fund's performance benchmark - the Lehman Brothers Government Bond Index - returned +4.39% and its peer group - as measured by the Lipper General U.S. Government Funds Average - returned +4.75% (source: Lipper Inc.). Q: WHAT FACTORS INFLUENCED FUND PERFORMANCE FOR THE FISCAL YEAR PERIOD? A: With regard to the Federal Reserve Board and its policy of raising short-term rates in 25-basis point (0.25%) increments, we believed the front-end of the yield curve would be susceptible to coupon-type returns, in which price appreciation would play little, if any, role in influencing Fund performance. Conversely, we believed the back-end of the yield curve could potentially benefit from the confluence of key forces at work within the fixed income markets, as with the Federal Reserve's continued endorsement of higher rates, rising petroleum prices, and demand from foreign investors for long-dated domestic debt. We viewed the combination of these factors as supporting the thesis of a gearing down of the global economy, resulting in this year's notable "bull flattening trade." Q: DESCRIBE SOME BROAD DECISIONS YOU APPLIED TO THE FUND'S PORTFOLIO. A: In 2005, for example, we believed Fund performance focused on security and sector decisions, as well as yield curve placement, and less on interest rate considerations. We favored a high-quality exposure in the front-end of the yield curve, allocating assets to mortgage-backed securities (MBS). To a lesser degree, we employed asset-backed securities (ABS); to a greater degree, we used agency bonds. Q: WHAT INFLUENCED PERFORMANCE IN THE FUND? A: TIPS retreated during the second quarter of 2005, thereby taking back the gains they had experienced earlier in the year. On the other hand, we believe the Fund benefited from investments we positioned strategically along the yield curve. In the short end, we believe hybrid mortgages aided Fund return. In the middle, Fannie Mae subordinated debt benefited from the flattening yield curve, as did agency zero-coupon bonds, specifically REFCO strips, in the long end. Q: HOW MIGHT YOU MANAGE THE FUND IF SHORT-TERM RATES STABILIZE? A: With the prospect of the Federal Reserve Board ending its campaign of raising short-term rates - likely in our view in the 3.75% to 4.00% range - we would anticipate to unravel the bias that's currently in the Fund, gearing it toward a flattening yield curve. We may instead favor a "bullet" investment strategy, whereby bond maturities may tend to be focused on one point of the yield curve. 1 PERFORMANCE SUMMARY DELAWARE AMERICAN GOVERNMENT BOND 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 American Government Bond Fund prospectus contains this and other important information about the investment company. Please request a prospectus by calling 800 523-1918. Read it carefully before you invest or send money. Performance includes reinvestment of all distributions. FUND PERFORMANCE Average Annual Total Returns Through July 31, 2005 Lifetime 10 Years Five Years One Year - -------------------------------------------------------------------------------- Class A (Est. 8/16/85) Excluding Sales Charge +6.64% +5.74% +6.36% +4.60% Including Sales Charge +6.39% +5.25% +5.38% -0.10% - -------------------------------------------------------------------------------- Class B (Est. 5/2/94) Excluding Sales Charge +5.14% +5.14% +5.61% +3.87% Including Sales Charge +5.14% +5.14% +5.37% -0.13% - -------------------------------------------------------------------------------- Class C (Est. 11/29/95) Excluding Sales Charge +4.79% +5.60% +3.87% Including Sales Charge +4.79% +5.60% +2.87% - -------------------------------------------------------------------------------- Returns reflect the reinvestment of all distributions and any applicable sales charges as noted below. Performance for Class B and C shares, excluding sales charges, assumes either that contingent deferred sales charges did not apply or the investment was not redeemed. The Fund offers Class A, B, C, R, and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50% and have an annual distribution and service 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 Class A shares on a quarterly basis approximately eight years after purchase. They are also subject to an annual distribution and service fee of 1%. Lifetime and 10-year performance figures for Class B shares reflect conversion to Class A shares 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 1%. The average annual total returns for the lifetime and one-year periods ended July 31, 2005 for Delaware American Government Bond Fund's Class R shares were 1.78% and 4.41%, respectively. Class R shares were first made available on June 2, 2003 and are available only for certain retirement plan products. They are sold without a sales charge and have an annual distribution and service fee of 0.60%. However, as of August 1, 2005, the Distributor has contracted to limit this amount to 0.50% through October 31, 2006. The average annual total returns for the lifetime (since 8/16/85), 10-year, five-year, and one-year periods ended July 31, 2005 for Delaware American Government Bond Fund's Institutional Class were +6.90%, +6.05%, 6.67%, and +4.91%, respectively. The Institutional Class shares were first made available on June 1, 1992 and are available without sales or asset-based distribution charges only to certain eligible institutional accounts. Institutional Class performance prior to June 1, 1992 for Delaware American Government Bond Fund is based on Class A performance and was adjusted to eliminate the sales charges, but not the asset-based distribution charge of Class A shares. An expense limitation was in effect for all classes of Delaware American Government Bond Fund during the 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 distributions or redemptions of Fund shares.

Performance of other Fund classes will vary due to different charges and expenses. The chart also assumes $10,000 invested in the Lehman Brothers Government Bond Index. Returns plotted on the chart were as of the last day of each successive month shown. The Lehman Brothers Government Bond Index is an unmanaged index that generally tracks the performance of U.S. Government bonds. An index is unmanaged and does not reflect the costs of operating a mutual fund, such as the costs of buying, selling, and holding securities. You cannot invest directly in an index. The performance graph does not reflect the deduction of taxes the shareholder would pay on fund distributions or redemption of Fund shares. An expense limitation was in effect for all classes of the Delaware American Government Bond Fund during the period shown. Performance would have been lower had the expense limitation not been in effect. Past performance is not a guarantee of future results. 3 DISCLOSURE For the Period February 1, 2005 to July 31, 2005 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 February 1, 2005 to July 31, 2005. 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 expenses shown in the table assume reinvestment of all dividends and distributions.

Effective August 1, 2005, DDLP has contracted to limit distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class R shares from exceeding 0.50% of average daily net assets. 4 SECTOR ALLOCATION As of July 31, 2005 DELAWARE AMERICAN GOVERNMENT BOND FUND Sector designations may be different than the sector designations presented in other Fund materials.

See accompanying notes 15 NOTES DELAWARE AMERICAN GOVERNMENT BOND FUND TO FINANCIAL STATEMENTS July 31, 2005 Delaware Group Government Fund (the "Trust") is organized as a Delaware statutory trust and offers two series: Delaware American Government Bond Fund and Delaware Inflation Protected Bond Fund. These financial statements and the related notes pertain to Delaware American Government Bond 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, Class R and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50%. 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 Class A 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. Class R and Institutional shares are not subject to a sale charge and are offered for sale exclusively to a limited group of investors. The investment objective of the Fund is to seek high current income consistent with safety of principal by investing primarily in debt obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities. 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 -- U.S. government and agency securities are valued at the mean between the bid and asked prices. Other long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Futures contracts and options on futures contracts are valued at the daily quoted settlement prices. Swap agreements and 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. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, or with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exhanges among dealers, or news events). 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. Repurchase Agreements -- The Fund may invest in a pooled cash account along with other members of the Delaware Investments Family of Funds pursuant to an exemptive order issued by the Securities and Exchange Commission. 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 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). 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. Realized gains (losses) on paydowns of mortgage- and asset-backed securities are classified as interest income. The Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. 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 year ended July 31, 2005 were approximately $7,048. 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 0.55% on the first $500 million of average daily net assets of the Fund, 0.50% on the next $500 million, 0.45% on the next $1.5 billion, and 0.425% on average daily net assets in excess of $2.5 billion. DMC has contractually agreed 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 0.75% of average daily net assets of the Fund through November 28, 2005. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective June 1, 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 June 1, 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 Class A shares, 1.00% of the average daily net assets of the Class B and C shares and 0.60% of the average daily net assets of the Class R shares. Institutional Class shares pay no distribution and service expenses. Effective August 1, 2005, DDLP has contracted to limit distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class R shares from exceeding 0.50% of average daily net assets. The Board of Trustees has adopted a formula for calculating 12b-1 plan fees for the Fund's Class A shares that went into effect on June 1, 1992. The total 12b-1 fees to be paid by Class A shareholders of the Fund will be the sum of 0.10% of the average daily net assets representing shares that were acquired prior to June 1, 1992 and 0.30% of the average daily net assets representing shares that were acquired on or after June 1, 1992. All Class A shareholders will bear 12b-1 fees at the same rate, the blended rate based upon the allocation of the 0.10% and 0.30% rates described above. 16 NOTES DELAWARE AMERICAN GOVERNMENT BOND FUND TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES (CONTINUED) At July 31, 2005, the Fund had liabilities payable to affiliates as follows: Investment management fee payable to DMC $78,055 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 31,750 Other expenses payable to DMC and affiliates* 75,707 *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 internal legal services provided to the Fund by DMC employees. For the year ended July 31, 2005, the Fund was charged $8,800 for internal legal services provided by DMC. For the year ended July 31, 2005, DDLP earned $10,182 for commissions on sales of the Fund's Class A shares. For the year ended July 31, 2005, DDLP received gross contingent deferred sales charge commissions of $--, $59,850 and $276 on redemption of the Fund's Class A, Class B and Class C shares, respectively, and 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. INVESTMENTS For the year ended July 31, 2005, the Fund made purchases of $197,714,082 and sales of $238,353,646 of investment securities other than long-term U.S. government securities and short-term investments. For the year ended July 31, 2005, the Fund made purchases of $264,437,791 and sales of $263,006,556 of long-term U.S. government securities. At July 31, 2005, the cost of investments for federal income tax purposes was $153,334,428. At July 31, 2005, the net unrealized depreciation was $1,287,113 of which $663,128 related to unrealized appreciation of investments and $1,950,241 related to unrealized depreciation of investments. 4. DIVIDEND AND DISTRIBUTION INFORMATION Income and long-term capital gain 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. The tax character of dividends and distributions paid during the years ended July 31, 2005 and 2004 was as follows: 2005 2004 ---------- ---------- Ordinary income $6,922,472 $8,091,043 Return of capital -- 704,700 ---------- ---------- $6,922,472 $8,975,743 ========== ========== As of July 31, 2005, the components of net assets on a tax basis were as follows: Shares of beneficial interest $167,722,529 Undistributed ordinary income 221,638 Capital loss carryforwards (15,658,139) Post-October losses (202,542) Unrealized depreciation of investments (1,287,113) ------------ Net assets $150,796,373 ============ The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales, mark-to-market on futures contracts and tax treatment of market discount and premium on debt instruments. Post-October losses represent losses realized on investment transactions from November 1, 2004 through July 31, 2005 that, in accordance with federal income tax regulations, the Fund has elected to defer and treat as having arisen in the following fiscal year. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount and premium on certain debt instruments and paydowns of mortgage- and asset-backed securities. Results of operations and net assets were not affected by these reclassifications. For the year ended July 31, 2005, the Fund recorded the following reclassifications: Undistributed net investment income $1,822,240 Accumulated net realized gain (loss) 549,334 Paid-in-capital (2,371,574) For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. $2,371,574 expired in 2005. Capital loss carry forwards will expire as follows: $3,195,086 expires in 2007; $6,907,431 expires in 2008; $1,219,236 expires in 2009; $2,497,064 expires in 2012, and $1,839,322 expires in 2013. 5. CAPITAL SHARES Transactions in capital shares were as follows: Year Ended 7/31/05 7/31/04 Shares sold: Class A 1,710,037 3,022,977 Class B 195,457 237,322 Class C 157,520 228,490 Class R 10,817 10,050 Institutional Class 558,128 1,231,246 Shares issued upon reinvestment of dividends and distributions: Class A 430,340 566,213 Class B 86,590 110,566 Class C 31,555 38,004 Class R 466 215 Institutional Class 159,136 180,839 ---------- ---------- 3,340,046 5,625,922 ---------- ---------- Shares repurchased: Class A (5,140,021) (7,867,124) Class B (1,102,040) (2,205,653) Class C (375,256) (521,129) Class R (1,915) (1,976) Institutional Class (1,001,450) (3,218,511) ---------- ---------- (7,620,682) (13,814,393) ---------- ---------- Net decrease (4,280,636) (8,188,471) ========== ========== For the years ended July 31, 2005 and 2004, 134,156 Class B shares were converted to 134,156 Class A shares valued at $1,037,538 and 220,824 Class B shares were converted to 220,824 Class A shares valued at $1,721,971, respectively. The respective amounts are included in Class B redemptions and Class A subscriptions in the table above and the Statements of Changes in Net Assets. 17 NOTES DELAWARE AMERICAN GOVERNMENT BOND FUND TO FINANCIAL STATEMENTS (CONTINUED) 6. LINE OF CREDIT The Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $183,100,000 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 amounts outstanding as of July 31, 2005, or at any time during the year. 7. FUTURES CONTRACTS The Fund may invest in financial futures contracts to hedge its existing portfolio securities against fluctuations in fair value caused by changes in prevailing market interest rates. Upon entering into a futures contract, the Fund deposits cash or pledges U.S. government securities to a broker, equal to the minimum "initial margin" requirements of the exchange on which the contract is traded. (In some cases, due to the form of the futures agreement, initial margin is held in a segregated account with the Fund's custodian, rather than directly with the broker.) Subsequent payments are received from the broker or paid to the broker (or added to the segregated account) each day, based on the daily fluctuation in the market value of the contract. These receipts or payments are known as "variation margin" and are recorded daily by the Fund as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risk of entering into futures contracts include potential imperfect correlation between the futures contracts and the underlying securities and the possibility of an illiquid secondary market for these instruments. 8. OPTIONS WRITTEN The Fund may enter into options contracts in accordance with its investment objectives. When the Fund writes an option, a premium is received and a liability is recorded and adjusted on a daily basis to reflect the current market value of the options written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is treated as realized gain or loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has a realized gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. The Fund had no options contract outstanding at July 31, 2005 or at any time during the year. 9. SWAP AGREEMENTS During the year ended July 31, 2005, the Fund entered into total return swap agreements in accordance with its investment objectives. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. Total return swaps involve commitments to pay interest in exchange for a market linked return based on a notional amount. To the extent the total return of the security, instrument or basket of instruments underlying the transaction exceeds the offsetting interest obligation, the Fund will receive a payment from the counterparty. To the extent the total return of the security, instrument or basket of instruments underlying the transaction falls short of the offsetting interest obligation, the Fund will make a payment to the counterparty. The change in value of swap agreements outstanding, if any, is recorded as unrealized appreciation or depreciation daily. A realized gain or loss is recorded on maturity or termination of the swap agreement. The Fund had no swap agreements outstanding at July 31, 2005. 10. CREDIT AND MARKET RISK The Fund may invest up to 20% of net assets in high quality non-government securities. Non-government securities include corporate bonds, certificates of deposit, corporate commercial paper, asset-backed securities and mortgage-backed securities that are not directly guaranteed by the U.S government in any way. Some of these securities are collateralized mortgage obligations (CMOs). CMOs are debt securities issued by U.S. government agencies or by financial institutions and other mortgage lenders, which are collateralized by a pool of mortgages held under an indenture. Prepayment of mortgages may shorten the stated maturity of the obligations and can result in a loss of premium, if any has been paid. Certain of these securities may be stripped (securities, which provide only principal or interest feature of the underlying security). The yield to maturity on an interest-only CMO is extremely sensitive not only to changes in prevailing interest rates, but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets. A rapid rate of principal payments may have a material adverse effect on the Fund's yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investments in these securities even if the securities are rated in the highest rating categories. The Fund may invest up to 10% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. At July 31, 2005, Rule 144A securities represented approximately 2.04% of total net assets. None of these securities has been determined to be illiquid under the Fund's Liquidity Procedures. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual Rule 144A securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. Illiquid securities have been denoted on the Statement of Net Assets. 11. 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. 12. 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. Accordingly, the information needed by shareholders for income tax purposes will be sent to them in January of each year. Please consult your tax advisor for proper treatment of this information. For the fiscal year ended July 31, 2005, the Fund designates distributions paid during the year as follows: (A) (B) Long-Term Ordinary Capital Gains Income Total Distributions Distributions Distributions (Tax Basis) (Tax Basis) (Tax Basis) ------------- ------------- ------------- -- 100% 100% (A) and (B) are based on a percentage of the Fund's total distributions. 18 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees Delaware Group Government Funds - Delaware American Government Bond Fund We have audited the accompanying statement of net assets of Delaware American Government Bond Fund (one of the series constituting Delaware Group Government Funds) (the "Fund") as of July 31, 2005, 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 periods indicated therein. 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 July 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 American Government Bond Fund of Delaware Group Government Funds at July 31, 2005, 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 periods indicated therein, in conformity with U.S. generally accepted accounting principles.

For Against Abstain Broker Non-Votes --- ------- ------- ---------------- Delaware American Government Bond Fund 12,180,679 867,617 501,417 2,378,708 BOARD CONSIDERATION OF DELAWARE AMERICAN GOVERNMENT BOND FUND INVESTMENT ADVISORY AGREEMENT At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Board of Trustees, including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory Agreement for the Delaware American Government Bond Fund (the "Fund"). In making its decision, the Board considered information furnished throughout the year at regular Board meetings, as well as information prepared specifically in connection with the Annual Meeting. Information furnished and discussed throughout the year included reports detailing Fund performance, investment strategies, expenses, compliance matters and other services provided by Delaware Management Company ("DMC"), the investment advisor. Information furnished specifically in connection with the Annual Meeting included materials provided by DMC and its affiliates ("Delaware Investments") concerning, among other things, the level of services provided to the Fund, the costs of such services to the Fund, economies of scale and the financial condition and profitability of Delaware Investments. In addition, in connection with the Annual Meeting, the Board separately received and reviewed independent historical and comparative reports prepared by Lipper Inc. ("Lipper"), an independent statistical compilation organization. The Lipper reports compared the Fund's investment performance and expenses with those of other comparable mutual funds. The Board also requested and received certain supplemental information regarding management's policy with respect to advisory fee levels and its philosophy with respect to breakpoints; the structure of portfolio manager compensation; the investment manager's profitability organized by client type, including the Fund; and any constraints or limitations on the availability of securities in certain investment styles which might inhibit the advisor's ability to fully invest in accordance with the Fund's policies. In considering such materials, the independent Trustees received assistance and advice from and met separately with independent counsel and representatives from Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman of the Delaware Investments(R) Family of Funds, and Chairman and Chief Executive Officer of the investment advisor, was present to respond to questions raised by Lipper and the independent Trustees. While the Board considered the Investment Advisory Agreements for all of the funds in the Delaware Investments(R) Family of Funds at the same Board meeting, information was provided and considered by the Board for each fund individually. In approving the continuance of the Investment Advisory Agreement for the Fund, the Board, including a majority of independent Trustees, determined that the existing advisory fee structure was fair and reasonable and that the continuance of the Investment Advisory Agreement was in the best interests of the Fund and its shareholders. While attention was given to all information furnished, the following discusses the primary factors relevant to the Board's deliberations and determination, including those relating to the selection of the investment advisor and the approval of the advisory fee. NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services provided by Delaware Investments to the Fund and its shareholders. In reviewing the nature, extent and quality of services, the Board emphasized reports furnished to it throughout the year at regular Board meetings covering matters such as the compliance of portfolio managers with the investment policies, strategies and restrictions for the Fund, the compliance of management personnel with the Code of Ethics adopted throughout the Delaware Investments(R) Family of Funds complex, the adherence to fair value pricing procedures as established by the Board, and the accuracy of net asset value calculations. The Board noted that it was pleased with the current staffing of the Fund's investment advisor during the past year, the emphasis on research and the compensation system for advisory personnel. Favorable consideration was given to DMC's efforts to maintain, and in some instances increase, financial and human resources committed to fund matters. Other factors taken into account by the Board were Delaware Investments' preparedness for, and response to, legal and regulatory matters. The Board also considered the transfer agent and shareholder services provided to Fund shareholders by Delaware Investments' affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate of the DALBAR Pyramid Award in four of the last six years 20 OTHER DELAWARE AMERICAN GOVERNMENT BOND FUND FUND INFORMATION (CONTINUED) BOARD CONSIDERATION OF DELAWARE AMERICAN GOVERNMENT BOND FUND INVESTMENT ADVISORY AGREEMENT (CONTINUED) and the continuing expenditures by Delaware Investments to increase and improve the scope of shareholder services. Additionally, the Board noted the extent of benefits provided to Fund shareholders for being part of the Delaware Investments(R) Family of Funds, including the privilege to exchange investments between the same class of funds without a sales charge, the ability to reinvest Fund dividends into other funds and the privilege to combine holdings in other funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent and quality of the overall services provided by Delaware Investments. INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC and the Fund. The Board was pleased by DMC's investment performance, noting Barron's ranking of the Delaware Investments(R) Family of Funds in the top quartile of mutual fund families for 2002 - 2004. The Board placed significant emphasis on the investment performance of the Fund in view of its importance to shareholders. While consideration was given to performance reports and discussions with portfolio managers at Board meetings throughout the year, particular attention in assessing performance was given to the Lipper reports furnished for the Annual Meeting. The Lipper reports prepared for the Fund showed the investment performance of its Class A shares in comparison to a group of similar funds as selected by Lipper (the "Performance Universe"). A fund with the highest performance is ranked first, and a fund with the lowest is ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25% - the second quartile; the next 25% - the third quartile; and the lowest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for the Fund was shown for the past one, three, five and 10 year periods ended February 28, 2005. The Board noted its objective that the Fund's performance be at or above the median of its Performance Universe. The following paragraph summarizes the performance results for the Fund and the Board's view of such performance. The Performance Universe for this Fund consisted of the Fund and all retail and institutional general U.S. government funds as selected by Lipper. The Lipper report comparison showed that the Fund's total return for the one, three and five year periods was in the first quartile of such Performance Universe. The report further showed that the Fund's total return for the 10 year period was in the second quartile. The Board was satisfied with such performance. COMPARATIVE EXPENSES. The Board considered expense comparison data for the Delaware Investments(R) Family of Funds, Delaware Investments' institutional separate account business and other lines of business at Delaware Investments. The Board stated its belief that, given the differing level of service provided to Delaware Investments' various clients and other factors that related to the establishment of fee levels, variations in the levels of fees and expenses were justified. The Board placed significant emphasis on the comparative analysis of the management fees and total expense ratios of the Fund compared with those of a group of similar funds as selected by Lipper (the "Expense Group") and among the other Delaware Investments(R) funds. In reviewing comparative costs, the Fund's contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees (as reported by each fund) of other funds within the Expense Group, taking into effect any applicable breakpoints and fee waivers. The Fund's total expenses were also compared with those of its Expense Group. The Lipper total expenses, for comparative consistency, were shown by Lipper for Class A shares and compared total expenses including 12b-1 and non-12b-1 service fees. The Board noted its objective to limit the Fund's total expense ratio to an acceptable range as compared to the median of the Expense Group. The following paragraph summarizes the expense results for the Fund and the Board's view of such expenses. The expense comparisons for the Fund showed that its management fee was in the quartile with the lowest expenses of its Expense Group and its total expenses were in the quartile with the second lowest expenses of its Expense Group. The Board was satisfied with the management fees and total expenses of the Fund in comparison to its Expense Group as shown in the Lipper report. MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any, realized by Delaware Investments in connection with the operation of the Fund. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of Delaware Investments' business in providing management and other services to each of the individual funds and the Delaware Investments(R) Family of Funds as a whole. Specific attention was given to the methodology followed in allocating costs for the purpose of determining profitability. Management stated that the level of profits of Delaware Investments, to a certain extent, reflected operational cost savings and efficiencies initiated by Delaware Investments. The Board considered Delaware Investments' expenditures to improve services provided to fund shareholders and to meet additional regulatory and compliance requirements resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also considered the extent to which Delaware Investments might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as service provider to the Delaware Investments(R) Family of Funds, the benefits from allocation of fund brokerage to improve trading efficiencies and the use of "soft" commission dollars to pay for proprietary and non-proprietary research. At the Board's request, management also provided information relating to Delaware Investments' profitability by client type. The information provided set forth the revenue, expenses and pre-tax income/loss attributable to the Delaware Investments(R) Family of Funds, Delaware Investments' separate account business and other lines of business at Delaware Investments. Emphasis was given to the level and type of service provided to the various clients. The Board was satisfied with the level of profits realized by Delaware Investments from its relationships with the Fund and the Delaware Investments(R) Family of Funds. ECONOMIES OF SCALE. The Trustees considered whether economies of scale are realized by Delaware Investments as the Fund's assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees took into account the standardized advisory fee pricing and structure approved by the Board and shareholders as part of a complex-wide shareholder meeting conducted in 1998/1999. At that time, Delaware Investments introduced breakpoints to account for management economies of scale. The Board noted that the fee under the Fund's management contract fell within the standard structure. Although the Fund has not reached a size at which it can take advantage of breakpoints, the Board recognized that the fee was structured so that when the Fund grows, economies of scale may be shared. 21 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.

PORTFOLIO DELAWARE INFLATION PROTECTED BOND FUND MANAGEMENT REVIEW August 8, 2005 FUND MANAGER Stephen R. Cianci Senior Portfolio Manager Q: PLEASE DESCRIBE THE NATURE OF THE FIXED INCOME MARKETS DURING THE FISCAL PERIOD, WHICH FOR THIS RELATIVELY NEW INVESTMENT SPANS FROM DECEMBER 1, 2004 TO JULY 31, 2005. A: Through July 31, 2005, 10-year Treasury yields first moved down to a seven-month low of 3.9%, before beginning an ascent that would take them to 4.2% by fiscal year-end. During this period, a "bull flattening" trend was largely in place, with the yield spread between two- and 30-year Treasuries narrowing, given market uncertainty over U.S. economic growth prospects (source: Bloomberg L.P.). The tendency toward relatively low long-term yields was caused by foreign demand, a European economic slowdown, and likely investor perceptions of an "inflation-fighting" Federal Reserve Board. Perhaps Federal Reserve Chairman Alan Greenspan put it best, when in attempting to describe the sense of disconnect between rising short-term rates and muted longer-term bond yield, he used the term "conundrum." Additionally, the Federal Reserve Board remained committed to raising rates at "a measured pace." The Fed funds rate stood at 2.00% when the Fund was incepted, yet with five 25 basis point (0.25%) increases, the measure stood at 3.25% at our first fiscal period-end seven months later on July 31, 2005 (source: St. Louis Federal Reserve Bank). Q: WHAT WAS THE INFLATION ENVIRONMENT DURING THE 12-MONTH PERIOD? A: Breakeven spreads -- the difference between the real (or inflation-adjusted) 10-year Treasury Inflation Protected Securities (TIPS) yield and that for the nominal 10-year Treasury bond -- widened in March to the 2.8% level, denoting rising inflation expectations in the market. The breakeven rate thereafter fell to the 2.2% level in the 10-year maturity sector. Several factors contributed to this market backdrop. First and foremost, the Federal Reserve Board continued the policy of raising short-term rates at its "measured" pace. Commodity prices fell, though oil rose, as did the relative value of the U.S dollar. We believe the confluence of these events caused the Fund to lose relative return in a market in which the nominal 10-year Treasury yield rallied from 4.5% to 3.8%. While petroleum prices are currently advancing toward $70 per barrel, we nonetheless do not believe the market may reach the high breakeven spreads we experienced during the period, as pipeline inflationary pressures appear to be flattening out. Still, we are cautious in the short-term with regard to expectations for rising prices, and we expect to continue to hold a more neutral IPB weighting. Q: HOW WELL DID THE FUND PERFORM RELATIVE TO ITS BENCHMARK AND PEER GROUP? A: Delaware Inflation Protected Bond Fund returned 2.55% (Class A shares at net asset value with distributions reinvested) during the period December 1, 2004 to July 31, 2005. By comparison, the Fund's performance benchmark, the Lehman Brothers U.S. Treasury Inflation Protected Securities Index, returned 2.30% and its peer group, as measured by the Lipper Treasury Inflation Protected Securities Funds Average, returned 1.92% (source: Lipper Inc.). Q: WHAT BROAD MEASURES DID YOU TAKE DURING THE EIGHT-MONTH PERIOD THAT INFLUENCED FUND PERFORMANCE? A: The Fund benefited from our being nimble with regard to the allocation to inflation-protected bonds (IPB). In early 2005, when oil was making new highs, Fund return was positively impacted by our positioning in intermediate-maturity IPB. Performance was also enhanced in early 2005 in a declining dollar environment, as we held a small position in non-dollar European bonds with an unhedged currency position that amounted to roughly 1% of net assets. Generally speaking, we believe the market for IPB is one that is still misunderstood by investors. We also believe it is inefficient, and the opportunities presented by an inefficient market may create long-term value for shareholders. Furthermore, IPB may serve a meaningful role as a portfolio diversifier, when utilized within an asset allocation that might also include stocks, bonds, and real estate, among other investments. 1 19 PORTFOLIO DELAWARE INFLATION PROTECTED BOND FUND MANAGEMENT REVIEW (CONTINUED) Q: CAN YOU IDENTIFY FURTHER ACTIONS YOU TOOK DURING THE PERIOD THAT INFLUENCED THE FUND'S RETURN? A: We lowered our allocation to IPB, and specifically TIPS. In the first quarter of 2005, we held an allocation to IPB in excess of 95% of Fund net assets, but by late May/early June, that figure had fallen to 82% -- near the Fund's minimum exposure allowed. We have since increased that weighting to approximately the 90% level. More specifically, at roughly a 2.5% breakeven spread, we began reducing the Fund's allocation to TIPS while increasing its weighting in nominal Treasury securities. When breakeven spreads fell to the 2.2% level, we started liquidating the nominal Treasuries and buying back the TIPS in an auction where significant supply of 5-, 10-, and 20- year TIPS came to market, representing yet another notable factor that influenced events during the period. Q: AS THE FUND MAY HOLD A SMALL NON-IPB ALLOCATION, WERE YOU ABLE TO LEVERAGE THIS FEATURE OF THE FUND? A: Yes, we generated excess return with small allocations in short-dated mortgage-backed securities and investment grade floating rate bonds. We expect to continue to seek opportunities beyond IPB as a means of enhancing performance, and will aim to do so without elevating risk in the Fund. 2 This page intentionally left blank. 3 PERFORMANCE SUMMARY DELAWARE INFLATION PROTECTED BOND FUND The performance data quoted represent past performance; past performance does not guarantee future results. Investment return and principal value will fluctuate so your shares, when redeemed, may be worth more or less than their original cost. 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 Inflation Protected Bond Fund prospectus contains this and other important information about the investment company. 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. FUND PERFORMANCE Total Returns Through July 31, 2005 Lifetime - -------------------------------------------------------------------------------- Class A (Est. 12/1/04) Excluding Sales Charge +2.55% Including Sales Charge -2.05% - -------------------------------------------------------------------------------- Class B (Est. 12/1/04) Excluding Sales Charge +2.37% Including Sales Charge -1.60% - -------------------------------------------------------------------------------- Class C (Est. 12/1/04) Excluding Sales Charge +2.37% Including Sales Charge +1.38% - -------------------------------------------------------------------------------- Returns reflect the reinvestment of distributions and any applicable sales charges as noted below. Performance for Class B and C shares, excluding sales charges, assumes either that contingent deferred sales charges did not apply or the investment was not redeemed. The Fund offers Class A, B, C, and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50% and have an annual distribution and service fee of up to 0.25%. 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 Class A shares on a quarterly basis approximately eight years after purchase. They are also subject to an annual distribution and service fee of 1%. 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 1%. The cumulative total return for the lifetime period ended July 31, 2005 for Delaware Inflation Protected Bond Fund's Institutional Class was +2.61%. The Institutional Class shares were first made available on December 1, 2004 and are available without sales or asset-based distribution charges only to certain eligible institutional accounts. An expense limitation was in effect for all classes of Delaware Inflation Protected Bond Fund during the 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 distributions or redemptions of Fund shares.

Returns plotted on the chart were as of the last day of each month shown. The Lehman Brothers U.S. Treasury Inflation Protected Securities Index is an unmanaged index that generally tracks the performance of the market for U.S. Treasury inflation protected securities. An index is unmanaged and does not reflect the costs of operating a mutual fund, such as the costs of buying, selling, and holding securities. You cannot invest directly in an index. The performance graph does not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemption of Fund shares. An expense limitation was in effect for all classes of the Delaware Inflation Protected Bond Fund during the period shown. Performance would have been lower had the expense limitation not been in effect. Past performance is not a guarantee of future results. 5 DISCLOSURE For the Period February 1, 2005 to July 31, 2005 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 February 1, 2005 to July 31, 2005. 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.

Prior to May 1, 2005, Delaware Distributors, L.P. elected voluntarily to waive the distribution and service fees of Class A, Class B, and Class C shares. These expense ratios do reflect this voluntary waiver. 6 SECTOR/COUNTRY ALLOCATION As of July 31, 2005 DELAWARE INFLATION PROTECTED BOND FUND Sector designations may be different than the sector designations presented in other Fund materials.

See accompanying notes 12 NOTES DELAWARE INFLATION PROTECTED BOND FUND TO FINANCIAL STATEMENTS July 31, 2005 Delaware Group Government Fund (the "Trust") is organized as a Delaware statutory trust and offers two series: Delaware American Government Bond Fund and Delaware Inflation Protected Bond Fund. These financial statements and the related notes pertain to Delaware Inflation Protected Bond Fund (the "Fund"). The Trust is an open-end investment company. The Fund is considered non-diversified under the Investment Company Act of 1940, as amended, and offers Class A, Class B, Class C and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50%. 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 Class A 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. Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to a limited group of investors. The investment objective of the Fund is to seek to provide inflation protection and current income. 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 listed on a foreign exchange are valued at the last quoted sales price before the Fund is valued. U.S. government and agency securities are valued at the mean between the bid and asked prices. Other long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Forward foreign currency exchange contracts (and forward foreign cross currency exchange contracts) are valued at the mean between the bid and ask prices of the contracts and are market-to-market daily. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Futures contracts and options on futures contracts are valued at the daily quoted settlement prices. 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. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, or with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchange among dealers, or news events). Federal Income Taxes -- The Fund intends 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, 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. Foreign Currency Transactions -- Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar daily. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Fund isolates that portion of realized gains and losses on investments in debt securities, which are due to changes in foreign exchange rates from that which are due to changes in market prices of debt securities. The Fund reports certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, where such components are treated as ordinary income (loss) for federal income tax purposes. 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). 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. Realized gains (losses) on paydowns of mortgage- and asset-backed securities are classified as interest income. The Fund declares and pays dividends from net investment income monthly and distributions from net realized gain on investments, if any, annually. 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 July 31, 2005 were approximately $553. 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 average daily net assets in excess of $2.5 billion. DMC has contractually agreed 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 0.50% of average daily net assets of the Fund through November 28, 2005. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective June 1, 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 June 1, 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 0.25% of the average daily net assets of the Class A shares and 1.00% of the average daily net assets of the Class B and C shares. Prior to May 1, 2005, DDLP elected voluntarily to waive the distribution and service fees of Class A, Class B and Class C shares. Institutional Class shares pay no distribution and service expenses. 13 NOTES DELAWARE INFLATION PROTECTED BOND FUND TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES (CONTINUED) At July 31, 2005, the Fund had receivables due from or liabilities payable to affiliates as follows: Reimbursement receivable from DMC $23,099 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC (330) Other expenses payable to DMC and affiliates* (4,575) *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, custodian fees and trustees' fees. 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 period ended July 31, 2005, the Fund was charged $187 for internal legal services provided by DMC. For the period ended July 31, 2005, DDLP earned $1,641 for commissions on sales of the Fund's Class A shares. For the period ended July 31, 2005, DDLP did not receive any contingent deferred sales charge commissions on redemption of the Fund's Class A, Class B and Class C 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. INVESTMENTS For the period ended July 31, 2005, the Fund made purchases of $788,905 and sales of $122,677 of investment securities other than U.S. government securities and short-term investments. For the period ended July 31, 2005, the Fund made purchases of $18,114,156 and sales of $12,897,812 of long-term U.S. government securities. At July 31, 2005, the cost of investments for federal income tax purposes was $5,910,945. At July 31, 2005, net unrealized depreciation was $84,296, of which $23,169 related to unrealized appreciation of investments and $107,465 related to unrealized depreciation of investments. 4. DIVIDEND AND DISTRIBUTION INFORMATION Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, gains (losses) on foreign currency transactions and net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the period ended July 31, 2005 was as follows: Ordinary income $176,662 As of July 31, 2005, the components of net assets on a tax basis were as follows: Shares of beneficial interest $5,861,171 Undistributed ordinary income 27,622 Post-October losses (2,523) Post-October currency losses (62) Unrealized depreciation of investments and foreign currencies (84,344) ---------- Net assets $5,801,864 ========== The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales, mark-to-market on futures contracts, mark-to-market of forward foreign currency contracts and tax treatment of market discount and premium on debt instruments. Post-October losses represent losses realized on investment and foreign currency transactions from November 1, 2004 through July 31, 2005 that, in accordance with federal income tax regulations, the Fund has elected to defer and treat as having arisen in the following fiscal year. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of gain (loss) on foreign currency transactions, market discount and premium on certain debt instruments and paydowns of mortgage- and asset-backed securities. Results of operations and net assets were not affected by these reclassifications. For the period ended July 31, 2005, the Fund recorded the following reclassifications: Undistributed net investment income $3,699 Accumulated net realized gain (loss) (3,699) 5. CAPITAL SHARES Transactions in capital shares were as follows: Period Ended 7/31/05 Shares sold: Class A 271,410 Class B 53,238 Class C 51,846 Institutional Class 200,001 Shares issued upon reinvestment of dividends and distributions: Class A 7,282 Class B 1,626 Class C 1,597 Institutional Class 6,879 ------- 593,879 ------- Shares repurchased: Class A (8,928) ------- (8,928) ------- Net increase 584,951 ======== 6. LINE OF CREDIT The Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $183,100,000 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 amounts outstanding as of July 31, 2005, or at any time during the period. 7. FOREIGN EXCHANGE CONTRACTS The Fund may enter into forward foreign currency exchange contracts (and forward foreign cross currency exchange contracts) as a way of managing foreign exchange rate risk. The Fund may enter into these contracts to fix the U.S. dollar value of a security that it has agreed to buy or sell for the period between the date the trade was entered into and the date the security is 14 NOTES DELAWARE INFLATION PROTECTED BOND FUND TO FINANCIAL STATEMENTS (CONTINUED) 7. FOREIGN EXCHANGE CONTRACTS (CONTINUED) delivered and paid for. The Fund may also use these contracts to hedge the U.S. dollar value of securities it already owns that are denominated in foreign currencies. The change in market value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of forward foreign currency exchange contracts (and forward foreign cross currency exchange contracts) does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although forward foreign currency exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. 8. FUTURES CONTRACTS The Fund may invest in financial futures contracts to hedge its existing portfolio securities against fluctuations in fair value caused by changes in prevailing market interest rates. Upon entering into a futures contract, the Fund deposits cash or pledges U.S. government securities to a broker, equal to the minimum "initial margin" requirements of the exchange on which the contract is traded. In some cases, due to the form of the futures agreement, initial margin is held in a segregated account with the Fund's custodian, rather than directly with the broker. Subsequent payments are received from the broker or paid to the broker (or added to the segregated account) each day, based on the daily fluctuation in the market value of the contract. These receipts or payments are known as "variation margin" and are recorded daily by the Fund as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risks of entering into futures contracts include potential imperfect correlation between the futures contracts and the underlying securities and the possibility of an illiquid secondary market for these instruments. 9. CREDIT AND MARKET RISK The Fund primarily invests in inflation protected debt securities whose principal and/or interest payments are adjusted for inflation, unlike traditional debt securities that make fixed principal and interest payments. Under normal circumstances, the Fund will invest at least 80% of its net assets in inflation protected debt securities issued by the U.S. government, its agencies or instrumentalities, foreign governments and corporations. Some countries in which the Fund may invest require governmental approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. In addition, if there is deterioration in a country's balance of payments or for other reasons, a country may impose temporary restrictions on foreign capital remittances abroad. The securities exchanges of certain foreign markets are substantially smaller, less liquid and more volatile than the major securities markets in the United States. Consequently, acquisition and disposition of securities by the Fund may be inhibited. In addition, a significant portion of the aggregate market value of equity securities listed on the major securities exchanges in emerging markets are held by a smaller number of investors. This may limit the number of shares available for acquisition or disposition by the Fund. The Fund also invests in fixed-income securities whose value is derived from an underlying pool of mortgages or consumer loans. Investors receive principal and interest payments as the underlying mortgages and consumer loans are paid back. Some of these securities are collateralized mortgage obligations (CMOs). CMOs are debt securities issued by U.S. government agencies or by financial institutions and other mortgage lenders, which are collateralized by a pool of mortgages held under an indenture. Prepayment of mortgages may shorten the stated maturity of the obligations and can result in a loss of premium, if any has been paid. Certain of these securities may be stripped (securities, which provide only the principal or interest feature of the underlying security). The yield to maturity on an interest-only CMO is extremely sensitive not only to changes in prevailing interest rates, but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets. A rapid rate of principal payments may have a material adverse affect on the Fund's' yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities even if the securities are rated in the highest rating categories. The Fund may invest up to 15% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual Rule 144A securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. At July 31, 2005, there were no Rule 144A securities. 10. 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. 11. TAX INFORMATION (UNAUDITED) The information set forth below is for the Fund's fiscal period 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. Accordingly, the information needed by shareholders for income tax purposes will be sent to them in January of each year. Please consult your tax advisor for proper treatment of this information. For the fiscal year ended July 31, 2005, the Fund designates distributions paid during the year as follows: (A) (B) Long-Term Ordinary Capital Gains Income Total Distributions Distributions Distributions (Tax Basis) (Tax Basis) (Tax Basis) -------------- -------------- -------------- -- 100% 100% (A) and (B) are based on a percentage of the Fund's total distributions. 15 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees Delaware Group Government Funds - Delaware Inflation Protected Bond Fund We have audited the accompanying statement of net assets of Delaware Inflation Protected Bond Fund (one of the series constituting Delaware Group Government Funds) (the "Fund") as of July 31, 2005, and the related statement of operations, statement of changes in net assets, and financial highlights for the period December 1, 2004 (commencement of operations) through July 31, 2005. 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 audit. We conducted our audit 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. ur audit 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 July 31, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides 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 Inflation Protected Bond Fund of Delaware Group Government Funds at July 31, 2005, the results of its operations, the changes in its net assets, and its financial highlights for the period December 1, 2004 (commencement of operations) through July 31, 2005, in conformity with U.S. generally accepted accounting principles.
