FUND MANAGERS

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.

PERFORMANCE SUMMARY
  DELAWARE AMERICAN GOVERNMENT 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 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.

- --------------------------------------------------------------------------------

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.

Chart assumes $10,000 invested on July 31, 1995 and includes the effect of a
4.50% front-end sales charge and the reinvestment of all distributions.
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.

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.

(1) As required, effective August 1, 2001, the Fund adopted the provisions of
    the AICPA Audit and Accounting Guide for Investment Companies that requires
    amortization of all premiums and discounts on debt securities and the
    recording of paydown gains and losses on mortgage- and asset-backed
    securities as an adjustment to interest income. The effect of these changes
    for the year ended July 31, 2002 was a decrease in net investment income per
    share of $0.076, an increase in net realized and unrealized gain (loss) per
    share of $0.076, and a decrease in the ratio of net investment income to
    average net assets by 0.99%. Per share data and ratios for the periods prior
    to August 1, 2001 have not been restated to reflect this change in
    accounting.

(2) Total investment return is based on the change in net asset value of a share
    for the period and assumes reinvestment of dividends and distributions at
    net asset value and does not reflect the impact of a sales charge. Total
    investment return reflects waivers and payment of fees by the manager, as
    applicable. Performance would have been lower had the expense limitation not
    been in effect.

(1) As required, effective August 1, 2001, the Fund adopted the provisions of
    the AICPA Audit and Accounting Guide for Investment Companies that requires
    amortization of all premiums and discounts on debt securities and the
    recording of paydown gains and losses on mortgage- and asset-backed
    securities as an adjustment to interest income. The effect of these changes
    for the year ended July 31, 2002 was a decrease in net investment income per
    share of $0.076, an increase in net realized and unrealized gain (loss) per
    share of $0.076, and a decrease in the ratio of net investment income to
    average net assets by 0.99%. Per share data and ratios for the periods prior
    to August 1, 2001 have not been restated to reflect this change in
    accounting.

(2) Total investment return is based on the change in net asset value of a share
    for the period and assumes reinvestment of dividends and distributions at
    net asset value and does not reflect the impact of a sales charge. Total
    investment return reflects waivers and payment of fees by the manager, as
    applicable. Performance would have been lower had the expense limitation not
    been in effect.

(1) As required, effective August 1, 2001, the Fund adopted the provisions of
    the AICPA Audit and Accounting Guide for Investment Companies that requires
    amortization of all premiums and discounts on debt securities and the
    recording of paydown gains and losses on mortgage- and asset-backed
    securities as an adjustment to interest income. The effect of these changes
    for the year ended July 31, 2002 was a decrease in net investment income per
    share of $0.076, an increase in net realized and unrealized gain (loss) per
    share of $0.076, and a decrease in the ratio of net investment income to
    average net assets by 0.99%. Per share data and ratios for the periods prior
    to August 1, 2001 have not been restated to reflect this change in
    accounting.

(2) Total investment return is based on the change in net asset value of a share
    for the period and assumes reinvestment of dividends and distributions at
    net asset value. Total investment return reflects waivers and payment of
    fees by the manager. Performance would have been lower had the expense
    limitation not been in effect.

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.

  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.

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

      --                          100%                       100%

(A) and (B) are based on a percentage of the Fund's total distributions.

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.

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

  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.

  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.
Trustees establish procedures and oversee and review the performance of the
investment manager, the distributor and others that perform services for the
fund. The independent fund trustees, in particular, are advocates for
shareholder interests. The following is a list of the Trustees and Officers with
certain background and related information.

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.

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.

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.

Chart assumes $10,000 invested on December 1, 2004 and includes the effect of a
4.50% front-end sales charge and the reinvestment of all distributions.
Performance of other Fund classes will vary due to different charges and
expenses. The chart also assumes $10,000 invested in the Lehman Brothers U.S.
Treasury Inflation Protected Securities Index. 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.

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.

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.

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)

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

           --               100%                100%

(A) and (B) are based on a percentage of the Fund's total distributions.

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.

  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.
Trustees establish procedures and oversee and review the performance of the
investment manager, the distributor and others that perform services for the
fund. The independent fund trustees, in particular, are advocates for
shareholder interests. The following is a list of the Trustees and Officers with
