FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED AUGUST 31, 2005, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE For the fiscal year that ended
August 31, 2005, several factors contributed to Oppenheimer U.S. Government
Trust's competitive total return and yield, as well as its favorable ranking
among its peers, amidst somewhat challenging macro conditions. First, our active
management of the Fund's exposure (vis-a-vis the benchmark) to mortgage-related
securities benefited performance. In the first half of the Fund's fiscal year,
this segment of the U.S. government securities market enjoyed solid
outperformance over Treasuries while providing favorable relative yield. As
such, our decision to substantially overweight our exposure to mortgage-backed
securities over the first half of the reporting period definitively added to
performance.

      With a landscape of stable mortgage rates and tame prepayments, mortgage
investors had little to complain about throughout the period. This stability
fostered consistent demand for mortgage securities from money managers, banks
and foreign investors throughout the period. This being said, midway through the
period we determined that certain sectors of the mortgage market had become less
attractive and we subsequently trimmed some of our overall mortgage exposure.
Some of our emphasis instead was shifted to commercial mortgage-backed
securities and agency debentures, segments of the market that continued to
outperform treasuries over the later half of the period, while residential
mortgages only kept pace with treasuries. As a result, this tactical shift
supported Fund returns.

      Throughout the year, our emphasis on higher-coupon mortgages within our
residential-mortgage exposure proved to be another boon to returns. As
valuations became what we considered unattractive in the mortgage sector, we
trimmed our overall exposure to the sector by reducing the Fund's exposure to
lower-coupon issues while maintaining our emphasis on higher-coupon mortgages,
which have continued to outperform in an environment of low volatility.

      The Fund's overall exposure to and emphasis on U.S. government
agency-related debt also added to returns. Agency debentures delivered
additional yield relative to Treasuries this period, and thanks in part to
limited overall supply, this segment of the government securities markets
enjoyed moderate spread tightening versus Treasuries, thereby outperforming from
a total return perspective.

      Finally, the portfolio's interest-rate exposure, also known as "duration,"
provided a definitive impact to Fund performance. When we entered the period,
the Fund's portfolio held less interest-rate sensitivity than did the benchmark.
This decision was based on our belief that the markets were "off" in their
expectations for a slow rate of convergence between short and long rates at that
time. In short, we were of the opinion that

FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

longer-term rates were artificially low. When rates spiked in March, our
duration positioning substantially added to returns, particularly versus many of
our peers. However, as the first half of 2005 came to a close longer-term
interest rates had returned to their lowest levels of the year. Therefore, we
further reduced our interest-rate sensitivity as we became even more convinced
that the markets were underestimating the extent of rate increases moving
forward. As the period ended, we maintained a moderate underweight duration
position versus the Fund's benchmark, having reduced our extreme underweight
position in July after interest rates increased moderately.

      While it is difficult to identify a factor that detracted from the Fund's
performance, had we been more aggressive in adjusting our interest-rate
sensitivity, the additional returns we enjoyed from this factor might have been
more significant. However, our disciplined investment process does not include
reacting to short-term interest-rate volatility or other short-term, macro
conditions. Furthermore, we believe to do so would have introduced unnecessary
risk to the Fund's portfolio. We believe that the Fund's performance results as
well as its favorable peer ranking this period exhibit the tried-and-true
strength of our investment process and approach, which includes seeking to
minimize risk to principal whenever possible.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until August 31, 2005. In the case of Class A, Class B and Class C
shares, performance is measured over a ten-fiscal-year period. In the case of
Class N shares, performance is measured from inception of the Class on March 1,
2001. In the case of Class Y shares, performance is measured from the inception
of the Class on May 18, 1998. The Fund's performance reflects the deduction of
the maximum initial sales charge on Class A shares, the applicable contingent
deferred sales charge on Class B, Class C, and Class N shares, and reinvestments
of all dividends and capital gains distributions. Past performance cannot
guarantee future results.

      The Fund's performance is compared to that of the Lehman Brothers U.S.
Government Bond Index, an unmanaged index including all U.S. Treasury issues,
publicly issued debt of U.S. Government agencies and quasi-public corporations
and U.S. Government guaranteed corporate debt, and is widely regarded as a
general measurement of the performance of the U.S. Government bond market. Index
performance reflects the reinvestment of income but does not consider the effect
of transaction costs, and none of the data in the graphs shows the effect of
taxes. The Fund's performance reflects the effects of the Fund's business and
operating expenses. While index comparisons may be useful to provide a benchmark
for the Fund's performance, it must be noted that the Fund's investments are not
limited to the investments in the index.

NOTES
- --------------------------------------------------------------------------------

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares.

Investors should consider the Fund's investment objectives, risks, and other
charges and expenses carefully before investing. The Fund's prospectus contains
this and other information about the Fund, and may be obtained by asking your
financial advisor, calling us at 1.800.525.7048 or visiting our website at
www.oppenheimerfunds.com. Read the prospectus carefully before investing.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by OppenheimerFunds,
Inc.

CLASS A shares of the Fund were first publicly offered on 8/16/85. Class
A returns include the current maximum initial sales charge of 4.75%.

CLASS B shares of the Fund were first publicly offered on 7/21/95. Class B
returns include the applicable contingent deferred sales charge of 5% (1-year)
and 2% (5-year). Class B shares are subject to an annual 0.75% asset-based sales
charge. Because Class B shares convert to Class A shares 72 months after
purchase, Class B performance does not include contingent deferred sales charge
and uses Class A performance for the period after conversion.

CLASS C shares of the Fund were first publicly offered on 12/1/93. Class C
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class C shares are subject to an annual 0.75% asset-based sales charge.

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are 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 examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended August 31, 2005.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line 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 "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, 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 for
the class of shares you hold 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 front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in


                     18 | OPPENHEIMER U.S. GOVERNMENT TRUST



the Statement of Additional Information). Therefore, the "hypothetical" lines of
the table are 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.

Class Y Hypothetical                      1,000.00    1,022.33    2.91

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended August 31, 2005 are as follows:

CLASS         EXPENSE RATIOS
- ----------------------------
Class A           0.90%
- ----------------------------
Class B           1.65
- ----------------------------
Class C           1.65
- ----------------------------
Class N           1.15
- ----------------------------
Class Y           0.57

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Manager and Transfer Agent that can be terminated at any time,
without advance notice. The "Financial Highlights" tables in the Fund's
financial statements, included in this report, also show the gross expense
ratios, without such waivers or reimbursements.

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Illiquid security. The aggregate value of illiquid securities as of August
31, 2005 was $11,048,335, which represents 1.07% of the Fund's net assets. See
Note 8 of Notes to Financial Statements.

2. Represents the current interest rate for a variable or increasing rate
security.

3. Issue is in default. Non-income producing. See Note 1 of Notes to Financial
Statements.

4. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows. These securities amount to $34,032,500 or 3.30% of the Fund's net assets
as of August 31, 2005.

5. When-issued security or forward commitment to be delivered and settled after
August 31, 2005. See Note 1 of Notes to Financial Statements.

6. All or a portion of the security is held in collateralized accounts to cover
initial margin requirements on open futures sales contracts. The aggregate
market value of such securities is $8,930,034. See Note 5 of Notes to Financial
Statements.

7. Zero coupon bond reflects effective yield on the date of purchase.

8. Partial or fully-loaned security. See Note 9 of Notes to Financial
Statements.

9. The security has been segregated to satisfy the forward commitment to return
the cash collateral received in securities lending transactions upon the
borrower's return of the securities loaned. See Note 9 of Notes to Financial
Statements.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer U.S. Government Trust (the Fund) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Fund's investment objective is to seek high current income consistent with
preservation of capital. The Fund's investment advisor is OppenheimerFunds, Inc.
(the Manager).

      The Fund offers Class A, Class B, Class C, Class N and Class Y shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end sales charge. Class B, Class C and Class N shares are
sold without a front-end sales charge but may be subject to a contingent
deferred sales charge (CDSC). Class N shares are sold only through retirement
plans. Retirement plans that offer Class N shares may impose charges on those
accounts. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC, however, the institutional investor
may impose charges on those accounts. All classes of shares have identical
rights and voting privileges with respect to the Fund in general and exclusive
voting rights on matters that affect that class alone. Earnings, net assets and
net asset value per share may differ due to each class having its own expenses,
such as transfer and shareholder servicing agent fees and shareholder
communications, directly attributable to that class. Class A, B, C and N have
separate distribution and/or service plans. No such plan has been adopted for
Class Y shares. Class B shares will automatically convert to Class A shares six
years after the date of purchase.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of The New York Stock Exchange (the Exchange), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities listed
or traded on National Stock Exchanges or other domestic exchanges are valued
based on the last sale price of the security traded on that exchange prior to
the time when the Fund's assets are valued. Securities traded on NASDAQ are
valued based on the closing price provided by NASDAQ prior to the time when the
Fund's assets are valued. In the absence of a sale, the security is valued at
the last sale price on the prior trading day, if it is within the spread of the
closing "bid" and "asked" prices, and if not, at the closing bid price.
Securities traded on foreign exchanges are valued based on the last sale price
on the principal exchange on which the security is traded, in the country that
is identified by the portfolio pricing service, prior to the time when the
Fund's assets are valued. In the absence of a sale, the security is valued at
the official closing price on the principal exchange. Corporate, government and
municipal debt instruments having a remaining maturity in excess of sixty days
and all mortgage-backed securities will be valued at the mean between the "bid"
and "asked" prices. Futures contracts traded on a commodities or futures
exchange will be valued at the final settlement price or official closing price
on the principal exchange as reported by such principal exchange at its trading
session ending at, or most recently prior to, the time when the Fund's assets
are valued. Securities may be valued primarily


                     38 | OPPENHEIMER U.S. GOVERNMENT TRUST


using dealer-supplied valuations or a portfolio pricing service authorized by
the Board of Trustees. Securities (including restricted securities) for which
market quotations are not readily available are valued at their fair value.
Foreign and domestic securities whose values have been materially affected by
what the Manager identifies as a significant event occurring before the Fund's
assets are valued but after the close of their respective exchanges will be fair
valued. Fair value is determined in good faith using consistently applied
procedures under the supervision of the Board of Trustees. Short-term "money
market type" debt securities with remaining maturities of sixty days or less are
valued at amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment can take place up to ten days or more after the trade date.
Normally the settlement date occurs within six months after the trade date;
however, the Fund may, from time to time, purchase securities whose settlement
date extends six months or more beyond trade date. During this period, such
securities do not earn interest, are subject to market fluctuation and may
increase or decrease in value prior to their delivery. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The purchase of securities on a when-issued
basis or forward commitment may increase the volatility of the Fund's net asset
value to the extent the Fund executes such transactions while remaining
substantially fully invested. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of August 31, 2005, the Fund had purchased
$359,631,403 of securities issued on a when-issued basis or forward commitment
and sold $17,942,391 of securities issued on a when-issued basis or forward
commitment.

      In connection with its ability to purchase or sell securities on a
when-issued basis, the Fund may enter into forward roll transactions with
respect to mortgage-related securities. Forward roll transactions require the
sale of securities for delivery in the current month, and a simultaneous
agreement with the same counterparty to repurchase similar (same type, coupon
and maturity) but not identical securities on a specified future date. The Fund
records the incremental difference between the forward purchase and sale of each
forward roll as realized gain (loss) on investments or as fee income in the case
of such transactions that have an associated fee in lieu of a difference in the
forward purchase and sale price.

      Risks of entering into forward roll transactions include the potential
inability of the counterparty to meet the terms of the agreement; the potential
of the Fund to receive inferior securities at redelivery as compared to the
securities sold to the counterparty; counterparty credit risk; and the potential
pay down speed variance between the mortgage-related pools.

- --------------------------------------------------------------------------------
SECURITY CREDIT RISK. The Fund invests in high-yield securities, which may be
subject to a greater degree of credit risk, market fluctuations and loss of
income and principal, and

may be more sensitive to economic conditions than lower-yielding, higher-rated
fixed-income securities. The Fund may acquire securities in default, and is not
obligated to dispose of securities whose issuers subsequently default. As of
August 31, 2005, securities with an aggregate market value of $441,135,
representing 0.04% of the Fund's net assets, were in default.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders, therefore, no federal income or excise tax provision is
required.

The tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for August 31, 2005. Net assets of the
Fund were unaffected by the reclassifications.

TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the
Fund's independent trustees. Benefits are based on years of service and fees
paid to each trustee during the years of service. During the year ended August
31, 2005, the Fund's projected benefit obligations were increased by $5,906 and
payments of $14,956 were made to retired trustees, resulting in an accumulated
liability of $171,421 as of August 31, 2005.

      The Board of Trustees has adopted a deferred compensation plan for
independent trustees that enables trustees to elect to defer receipt of all or a
portion of the annual

compensation they are entitled to receive from the Fund. For purposes of
determining the amount owed to the Trustee under the plan, deferred amounts are
treated as though equal dollar amounts had been invested in shares of the Fund
or in other Oppenheimer funds selected by the Trustee. The Fund purchases shares
of the funds selected for deferral by the Trustee in amounts equal to his or her
deemed investment, resulting in a Fund asset equal to the deferred compensation
liability. Such assets are included as a component of "Other" within the asset
section of the Statement of Assets and Liabilities. Deferral of trustees' fees
under the plan will not affect the net assets of the Fund, and will not
materially affect the Fund's assets, liabilities or net investment income per
share. Amounts will be deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts at a rate equal to the Federal
Funds Rate plus 0.50%. The Reduction to Custodian Expenses line item, if
applicable, represents earnings on cash balances maintained by the Fund during
the period. Such interest expense and other custodian fees may be paid with
these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
OTHER. 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 and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

the Class A shares; 1.65% for Class B and Class C shares, respectively; 1.15%
for the Class N shares and 0.65% for the Class Y shares. During the year ended

5. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
commodity or financial instrument at a negotiated price on a stipulated future
date. Futures contracts are traded on a commodity exchange. The Fund may buy and
sell futures contracts that relate to broadly based securities indices
(financial futures) or debt securities (interest rate futures) in order to gain
exposure to or protection from changes in market value of stocks and bonds or
interest rates. The Fund may also buy or write put or call options on these
futures contracts.

      The Fund generally sells futures contracts as a hedge against increases in
interest rates and decreases in market value of portfolio securities. The Fund
may also purchase futures contracts to gain exposure to market changes as it may
be more efficient or cost effective than actually buying securities.

      Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund recognizes a realized gain or loss when the contract is
closed or has expired.

      Cash held by the broker to cover initial margin requirements on open
futures contracts is noted in the Statement of Assets and Liabilities.
Securities held in collateralized accounts to cover initial margin requirements
on open futures contracts are noted in the Statement of Investments. The
Statement of Assets and Liabilities reflects a receivable and/or payable for the
daily mark to market for variation margin. Realized gains and losses are
reported in the Statement of Operations as the closing and expiration of futures
contracts. The net change in unrealized appreciation and depreciation is
reported in the Statement of Operations.

      Risks of entering into futures contracts (and related options) include the

6. INTEREST RATE SWAP CONTRACTS

The Fund may enter into an interest rate swap transaction to maintain a total
return or yield spread on a particular investment, or portion of its portfolio,
or for other non-speculative purposes. Interest rate swaps involve the exchange
of commitments to pay or receive interest, e.g., an exchange of floating rate
payments for fixed rate payments. The coupon payments are based on an agreed
upon principal amount and a specified index. Because the principal amount is not
exchanged, it represents neither an asset nor a liability to either
counterparty, and is referred to as notional. The Fund records an increase or
decrease to unrealized gain (loss), in the amount due to or owed by the Fund at
termination or settlement.

      Interest rate swaps are subject to credit risk (if the counterparty fails
to meet its obligations) and interest rate risk. The Fund could be obligated to
pay more under its swap agreements than it receives under them, as a result of
interest rate changes.

As of August 31, 2005, the Fund had entered into the following interest rate
swap agreements:

7. TOTAL RETURN SWAP CONTRACTS

The Fund may enter into a total return swap transaction to maintain a total
return on a particular investment, or portion of its portfolio, or for other
non-speculative purposes. Because the principal amount is not exchanged, it
represents neither an asset nor a liability to either counterparty, and is
referred to as notional. The Fund records an increase or decrease to unrealized
gain (loss), in the amount due to or owed by the Fund at termination or
settlement. Total return swaps are subject to risks (if the counterparty fails
to meet its obligations).

- --------------------------------------------------------------------------------
8. ILLIQUID SECURITIES

As of August 31, 2005, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Fund will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
9. SECURITIES LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income. In return, the Fund receives collateral in the form of US
Treasury obligations or cash, against the loaned securities and maintains
collateral in an amount not less than 100% of the market value of the loaned
securities during the period of the loan. The market value of the loaned
securities is determined at the close of business of the funds and any
additional required collateral is delivered to the Fund on the next business
day. If the borrower defaults on its obligation to return the securities loaned
because of insolvency or other reasons, the Fund could experience delays and
cost in recovering the securities loaned or in gaining access to the collateral.
Cash collateral is invested in cash equivalents. The Fund retains a portion of
the interest earned from the collateral. The Fund continues to receive the
economic benefit of interest or dividends paid on the securities loaned in the
form of a substitute payment received from the borrower. As of August 31, 2005,
the Fund had on loan securities valued at $44,710,615. Collateral of $45,456,002
was received for the loans, of which $33,294,462 was received in cash and
subsequently invested in approved instruments.

10. LITIGATION

A consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor, as well as 51 of the
Oppenheimer funds (as "Nominal Defendants") including the Fund, 30 present and
former Directors or Trustees and 8 present and former officers of the funds.
This complaint, initially filed in the U.S. District Court for the Southern
District of New York on January 10, 2005 and amended on March 4, 2005,
consolidates into a single action and amends six individual previously-filed
putative derivative and class action complaints. Like those prior complaints,
the complaint alleges that the Manager charged excessive fees for distribution
and other costs, improperly used assets of the funds in the form of directed
brokerage commissions and 12b-1 fees to pay brokers to promote sales of the
funds, and failed to properly disclose the use of assets of the funds to make
those payments in violation of the Investment Company Act of 1940 and the
Investment Advisers Act of 1940. Also, like those prior complaints, the
complaint further alleges that by permitting and/or participating in those
actions, the Directors/Trustees and the Officers breached their fiduciary duties
to shareholders of the funds under the Investment Company Act of 1940 and at
common law. The complaint seeks unspecified compensatory and punitive damages,
rescission of the funds' investment advisory agreements, an accounting of all
fees paid, and an award of attorneys' fees and litigation expenses.

      The defendants believe that the allegations contained in the Complaints
are without merit and that they have meritorious defenses against the claims
asserted. The defendants intend to defend these lawsuits vigorously and to
contest any claimed liability. The defendants believe that it is premature to
render any opinion as to the likelihood of an outcome unfavorable to them and
that no estimate can yet be made with any degree of certainty as to the amount
or range of any potential loss.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER U.S. GOVERNMENT TRUST:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer U.S. Government Trust, including the statement of investments, as of
August 31, 2005, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the years
in the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

      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.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of August 31, 2005, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer U. S. Government Trust as of August 31, 2005, the results of its
operations for the year then ended, the changes in its net assets for each of
the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with U.S.
generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2006, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2005. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Dividends and distributions of $0.1805, $0.1741, $0.1732, $0.1783 and
$0.1830 per share were paid to Class A, Class B, Class C, Class N and Class Y
shareholders, respectively, on December 30, 2004, of which $0.0539 was
designated as a "capital gain distribution" for federal income tax purposes.
Whether received in stock or in cash, the capital gain distribution should be
treated by shareholders as a gain from the sale of the capital assets held for
more than one year (long-term capital gains).

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
advisory agreement. The Investment Company Act of 1940, as amended, requires
that the Board request and evaluate, and that the Manager provide, such
information as may be reasonably necessary to evaluate the terms of the advisory
agreement. The Board employs an independent consultant to prepare a report that
provides information, including comparative information, that the Board requests
for this purpose. In addition, the Board receives information throughout the
year regarding Fund services, fees, expenses and performance.

      NATURE AND EXTENT OF SERVICES. In considering the renewal of the Fund's
advisory agreement for the current year, the Board evaluated the nature and
extent of the services provided by the Manager and its affiliates. The Manager
provides the Fund with office space, facilities and equipment; administrative,
accounting, clerical, legal and compliance personnel; securities trading
services; oversight of third party service providers and the services of the
portfolio manager and the Manager's investment team, who provide research,
analysis and other advisory services in regard to the Fund's investments.

      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board noted that the Manager has had over forty years of experience as
an investment adviser and that its assets under management rank it among the top
mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services and information the
Board received regarding the experience and professional qualifications of the
Manager's personnel and the size and functions of its staff. The Board members
also considered their experiences as directors or trustees of the Fund and other
funds advised by the Manager. The Board received and reviewed information
regarding the quality of services provided by affiliates of the Manager, which
it also reviews at other times during the year in connection with the renewal of
the Fund's service agreements. The Board was aware that there are alternatives
to retaining the Manager.

      PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the
quality of the portfolio management services to be provided, the Board
considered the experience of the Fund's lead portfolio manager and the Manager's
fixed-income investment team and analysts. The Fund is managed by a portfolio
management team comprised of Angelo Manioudakis and other investment
professionals selected from the Manager's High-Grade Bond Team in its Fixed
Income department. Mr. Manioudakis has been a portfolio manager of the Fund
since April 2002. He has been a Vice President of the Fund and a Senior Vice
President of the Manager since April 2002 and is an officer and


                     54 | OPPENHEIMER U.S. GOVERNMENT TRUST



portfolio manager of other Oppenheimer funds. Mr. Manioudakis has had over 12
years of experience managing fixed-income investments.

      The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Fund's historical performance to relevant
market indices and to the performance of other U.S. government funds advised by
other investment advisers. The Board also receives and reviews comparative
performance information regarding the Fund and other funds at each Board
meeting. The Board considered that the Fund's one-year, three-year, five-year
and ten-year performance were better than its peer group average.

      MANAGEMENT FEES AND EXPENSES. The Board also reviewed information,
including comparative information, regarding the fees paid to the Manager and
its affiliates and the other expenses borne by the Fund. The independent
consultant provided comparative data in regard to the fees and expenses of the
Fund, other U.S. government funds and other funds with comparable asset levels
and distribution features. The Board noted that the Fund's contractual
management fee and total expenses were higher than its peer group average.
However, the Fund's actual management fee was lower than its peer group average.
In addition, the Board evaluated the comparability of the fees charged and the
services provided to the Fund to the fees charged and services provided to other
types of entities advised by the Manager. The Manager has agreed to voluntarily
limit expenses for all classes so that total annual operating expenses as a
percentage of average daily net assets would not exceed the following annual
rates: 0.90% for Class A shares, 1.65% for Class B shares, 1.65% for Class C
shares, 1.15% for Class N shares and 0.65% for Class Y shares. The Manager may
modify or terminate this undertaking at any time without notice to shareholders.
Based on its evaluation of the Fund's fees and expenses, the Board requested,
and the Manager agreed to revise the Fund's management fee schedule to lower the
fees for the first $200 million of average net assets. Accordingly, the
management fee schedule was changed to: 0.60% of the first $300 million of
average annual net assets of the Fund, 0.57% of the next $100 million, 0.55% of
the next $400 million, 0.50% of the next $1.2 billion, and 0.475% of average
annual net assets over $2.0 billion.

      PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed
information regarding the cost of services provided by the Manager and its
affiliates and the Manager's profitability. The Board considered that the
Manager must be able to pay and retain experienced professional personnel at
competitive rates to provide services to the Fund and that maintaining the
financial viability of the Manager is important in order for the Manager to
continue to provide significant services to the Fund and its shareholders. In
addition the Board considered information that was provided regarding the direct

indirect benefits the Manager receives as a result of its relationship with the
Fund, including compensation paid to the Manager's affiliates.

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund and the current
level of Fund assets in relation to the Fund's breakpoint schedule for its
management fees. The Board considered that the Fund has not experienced recent
asset growth and that, based on current asset levels, the Fund is not yet
approaching its last management fee breakpoint.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and the independent Trustees. Fund counsel is independent of the
Manager within the meaning and intent of the Securities and Exchange Commission
Rules.

      Based on its review of the information it received (including information
about the voluntary expense limitation) and its evaluations described above, the
Board, including a majority of the independent Trustees, concluded that the
nature, extent and quality of the services provided to the Fund by the Manager
are a benefit to the Fund and in the best interest of the Fund's shareholders
and that the amount and structure of the compensation received by the Manager
and its affiliates and the revised fee structure adopted by the Board and the
Manager are reasonable in relation to the services provided. Accordingly, the
Board elected to continue the advisory agreement for another year. In arriving
at this decision, the Board did not single out any factor or factors as being
more important than others, but considered all of the factors together. The
Board judged the terms and conditions of the advisory agreement, including the
management fee, in light of all of the surrounding circumstances.

ITEM 2. CODE OF ETHICS.

The registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller or persons performing similar functions.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the registrant has determined that the registrant does
not have an audit committee financial expert serving on its Audit Committee. In
this regard, no member of the Audit Committee was identified as having all of
the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR
to qualify as an "audit committee financial expert," whether



through the type of specialized education or experience described in that
Instruction. The Board has concluded that while the members of the Audit
Committee collectively have the necessary attributes and experience required to
serve effectively as an Audit Committee, no single member possesses all of the
required technical attributes through the particular methods of education or
experience set forth in the Instructions to be designated as an audit committee
financial expert.

registrant.

(e)   (1) During its regularly scheduled periodic meetings, the registrant's
      audit committee will pre-approve all audit, audit-related, tax and other
      services to be provided by the principal accountants of the registrant.

      The audit committee has delegated pre-approval authority to its Chairman
      for any subsequent new engagements that arise between regularly scheduled
      meeting dates provided that any fees such pre-approved are presented to
      the audit committee at its next regularly scheduled meeting.

      Under applicable laws, pre-approval of non-audit services maybe waived
      provided that: 1) the aggregate amount of all such services provided
      constitutes no more than five percent of the total amount of fees paid by
      the registrant to it principal accountant during the fiscal year in which
      services are provided 2) such services were not recognized by the
      registrant at the time of engagement as non-audit services and 3) such
      services are promptly brought to the attention of the audit committee of
      the registrant and approved prior to the completion of the audit.

      (2) 100%

(f)   Not applicable as less than 50%.

(g)   The principal accountant for the audit of the registrant's annual
      financial statements billed $137,059 in fiscal 2005 and $45,500 in fiscal
      2004 to the registrant and the registrant's investment adviser or any
      entity controlling, controlled by, or under common control with the
      adviser that provides ongoing services to the registrant related to
      non-audit fees. Those billings did not include any prohibited non-audit
      services as defined by the Securities Exchange Act of 1934.

(h)   The registrant's audit committee of the board of trustees has considered
      whether the provision of non-audit services that were rendered to the
      registrant's investment adviser, and any entity controlling, controlled
      by, or under common control with the investment adviser that provides
      ongoing services to the registrant that were not pre-approved pursuant to
      paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
      maintaining the principal accountant's independence.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and whether the individual would be
      deemed an "audit committee financial expert" within the meaning of
      applicable SEC rules. The Committee also considers whether the
      individual's background, skills, and experience will complement the
      background, skills, and experience of other nominees and will contribute
      to the Board. There are no differences in the manner in which the
      Committee evaluates nominees for trustees based on whether the nominee is
      recommended by a shareholder.



3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of August 31, 2005, the registrant's principal executive
officer and principal financial officer found the registrant's disclosure
controls and procedures to provide reasonable assurances that information
required to be disclosed by the registrant in the reports that it files under
the Securities Exchange Act of 1934 (a) is accumulated and communicated to
registrant's management, including its principal executive officer and principal
financial officer, to allow timely decisions regarding required disclosure, and
(b) is recorded, processed, summarized and reported, within the time



periods specified in the rules and forms adopted by the U.S. Securities and
Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.

ITEM 12. EXHIBITS.

(a)   (1) Exhibit attached hereto.

      (2) Exhibits attached hereto.

      (3) Not applicable.

(b)   Exhibit attached hereto.

Investment Company Act of 1940, the registrant has duly caused this report to be
