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, 2006, 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 ended August
31, 2006, several factors contributed to Oppenheimer U.S. Government Trust's
favorable ranking among its peer group of similarly managed funds, as well as to
the competitive yield and consistent total return it generated over the period.
To begin, the most significant factor supporting the Fund's performance for the
12-month review period was our active management of the portfolio's exposure to
interest-rate risk. Over the period, we successfully adjusted our duration, or
interest-rate sensitivity, such that we were able to not only profit from shifts
in rates, but also avoided unnecessary interest-rate risk, thereby helping to
buffer the Fund from potential losses. For example, we began the fiscal year
with a shorter duration than that of our benchmark, based on our evaluation of
market conditions in light of overall economic fundamentals.

      Yields dropped markedly after Hurricane Katrina, in what we considered to
be an overreaction by the markets, and as such, we further reduced the
portfolio's interest-rate sensitivity relative to that of the benchmark. This
decision benefited us considerably when yields increased once the initial shock
associated with that hurricane subsided. As the period progressed, we maintained
a somewhat shorter-than-benchmark duration, which continued to benefit the
Fund's returns, given the fact that rates in general increased throughout late
2005 and the first half of 2006. As we began to perceive that rates were rising
to a level that we deemed more in line with economic fundamentals, we decreased
the degree to which we were underweight duration relative to the benchmark. By
June 2006, we had moved to a more neutral posture in terms of interest-rate
sensitivity, as at that time, we were convinced the risk of rising rates was
roughly equal to the risk of decreasing rates. As the review period came to a
close, rates began to drift lower, and we again moved to a very small
underweight in duration relative to the benchmark. Overall, these minor
adjustments in our overall level interest-rate risk enabled us to successfully
benefit from the movement in rates over the Fund's fiscal year.

      Another factor that added to returns over the 12-month period was our
active management of the portfolio's mortgage holdings. First, our decision to
generally emphasize higher-coupon mortgages in the first half of the review
period supported performance, given the attractive risk/reward profile these
securities offered early in the period. For the first six months of the Fund's
fiscal year, these mortgages performed well for us, and added to our overall
returns. Second, we derived positive performance from opportunistically
adjusting our risk exposure to the overall mortgage sector. Specifically, we
began the

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

fiscal year with less mortgage risk than our benchmark, particularly in
lower-coupon mortgages, as we considered the sector overvalued at that point in
time. This underweight positioning substantially benefited the Fund's returns
when, in late 2005, the mortgage sector suffered relative to the overall
government securities market. Soon after, we perceived valuations in this sector
as attractive, and proceeded to overweight our exposure to mortgages relative to
the benchmark. This adjustment to our mortgage holdings proved very beneficial
to the Fund's relative performance when the mortgage sector performed quite
strongly in the first two months of 2006. Finally, after this strong performance
we perceived that mortgages had become richly valued, we began to trim back our
overweighted exposure to a more neutral posture, which is where we have been for
the latter half of the period.

      While our overall emphasis on agency debentures during the period was not
the largest contributor to the Fund's strong relative performance, its
contribution was very consistent. However, by the end of the period we perceived
that valuations in the agency sector had peaked relative to Treasury securities.
Therefore, much as we did with our mortgage holdings earlier in the period, we
reduced our overall agency exposure to a neutral position versus the benchmark,
reaping gains for the portfolio in the process.

      Finally, our decision to consistently overweight our exposure to
commercial mortgage-backed securities (CMBS) and select asset-backed securities
(ABS) has added to performance over the course of the fiscal year. These
securities are for the most part AAA-rated and in our opinion offer very
favorable return relative to risk characteristics. Since these holdings have
performed consistently well over the period, our decision to make best use of
our allowable exposure to these sectors as dictated by our prospectus has aided
overall Fund returns.

      While we still believe good value lies in the high-coupon segment of the
mortgage sector, we were slightly disappointed by the performance of our
higher-coupon mortgage holdings over the second half of the fiscal year. While
this emphasis didn't necessarily detract from performance, it didn't serve the
portfolio as well as we had hoped given recent trends in both the housing market
and in interest rates. As such, we might have given up marginal performance on a
relative basis due to our emphasis on higher-coupon mortgage securities during
the second half of the period. However, we are convinced that the performance of
these securities, after adjusted for their lower risk, was more than adequate.

      Fixed-income investing entails credit risks and interest rate risks. When
interest rates rise, bond prices generally fall and the Fund's share price can
fall.

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, 2006. 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.

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,
OR CALL US AT 1.800.525.7048. FUND RETURNS INCLUDE CHANGES IN SHARE PRICE,
REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE: FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 4.75%; FOR CLASS B SHARES, THE
CONTINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS C
AND N SHARES, THE CONTINGENT 1% DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD.
THERE IS NO SALES CHARGE FOR CLASS Y SHARES. BECAUSE CLASS B SHARES CONVERT TO
CLASS A SHARES 72 MONTHS AFTER PURCHASE, 10-YEAR RETURNS FOR CLASS B SHARES USES
CLASS A PERFORMANCE FOR THE PERIOD AFTER CONVERSION. SEE PAGE 19 FOR FURTHER
INFORMATION.

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, the 10-year return for Class B 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, 2006.

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


                     20 | 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          1,022.13          3.11

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, 2006 are as follows:

CLASS         EXPENSE RATIOS
- ----------------------------
Class A            0.90%
- ----------------------------
Class B            1.65
- ----------------------------
Class C            1.65
- ----------------------------
Class N            1.16
- ----------------------------
Class Y            0.61

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

2. Issue is in default. Non-income producing. See Note 1 of accompanying Notes.

3. Illiquid security. The aggregate value of illiquid securities as of August
31, 2006 was $427,825, which represents 0.05% of the Fund's net assets. See Note
8 of accompanying Notes.

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 $31,607,238 or 3.47% of the Fund's net assets
as of August 31, 2006.

5. When-issued security or forward commitment to be delivered and settled after
August 31, 2006. See Note 1 of accompanying Notes.

6. Principal-Only Strips represent the right to receive the monthly principal
payments on an underlying pool of mortgage loans. The value of these securities
generally increases as interest rates decline and prepayment rates rise. The
price of these securities is typically more volatile than that of coupon-bearing
bonds of the same maturity. Interest rates disclosed represent current yields
based upon the current cost basis and estimated timing of future cash flows.
These securities amount to $3,378,320 or 0.37% of the Fund's net assets as of
August 31, 2006.

7. 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 $7,208,510. See Note 5 of accompanying Notes.

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

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 may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. 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(R) 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, as 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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

trading session ending at, or most recently prior to, the time when the Fund's
assets are valued. 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, 2006, the Fund had purchased
$174,023,086 of securities issued on a when-issued basis or forward commitment
and sold $32,988,613 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.


                     42 | OPPENHEIMER U.S. GOVERNMENT TRUST


- --------------------------------------------------------------------------------
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, 2006, securities with an
aggregate market value of $73,311, representing 0.01% 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 provisions are
required, however, during the year ended August 31, 2006, the Fund paid federal
excise tax of $14,134.

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.

1. As of August 31, 2006, the Fund had $12,404,454 of net capital loss
carryforward available to offset future realized capital gains, if any, and
thereby reduce future taxable gain distributions. As of August 31, 2006, details
of the capital loss carryforward were as follows:

2. As of August 31, 2006, the Fund had $6,382,650 of post-October losses
available to offset future realized capital gains, if any. Such losses, if
unutilized, will expire in 2015.

3. The Fund had $137,181 of straddle losses which were deferred.

4. During the fiscal year ended August 31, 2006, the Fund did not utilize any
capital loss carryforward.

5. During the fiscal year ended August 31, 2005, the Fund did not utilize any
capital loss carryforward.

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, 2006.
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, 2006, the Fund's projected benefit obligations were decreased by $21,403 and
payments of $14,347 were made to retired trustees, resulting in an accumulated
liability of $135,671 as of August 31, 2006.

      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, to
the extent they are not offset by positive cash balances maintained by the Fund,
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.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Fund's organizational documents provide current and former
trustees and officers with a limited indemnification against liabilities arising
in connection with the performance of their duties to the Fund. In the normal
course of business, the Fund may also enter into contracts that provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown as this would be dependent on future claims that may be made against the
Fund. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
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.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund. The Fund pays
OFS a per account fee. For the year ended August 31, 2006, the Fund paid
$2,212,981 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 per
annum for assets of $10 million or more. The Class Y shares are subject to the
minimum fees in the event that the per account fee does not equal or exceed the
applicable minimum fees. OFS may voluntarily waive the minimum fees.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A
shares. It reimburses the Distributor for a portion of its costs incurred for
services provided to accounts that hold Class A shares. Reimbursement is made
periodically at an annual rate of up to 0.25% of the average annual net assets
of Class A shares of the Fund. The Distributor currently uses all of those fees
to pay dealers, brokers, banks and other financial institutions periodically for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
periods. Fees incurred by the Fund under the plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of those shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% on Class B and
Class C shares and 0.25% on Class N shares. The Distributor also receives a
service fee of 0.25% per year under each plan. If either the Class B, Class C or
Class N plan is terminated by the Fund or by the shareholders of a class, the
Board of Trustees and its independent trustees must determine whether the
Distributor shall be entitled to payment from the Fund of all or a portion of
the service fee and/or asset-based sales charge in respect to shares sold prior
to the effective date of such termination. The Distributor's aggregate
uncompensated expenses under the plan at August 31, 2006 for Class B, Class C
and Class N shares were $6,894,329, $2,836,161 and $679,264, respectively. Fees
incurred by the Fund under the plans are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective March 1, 2004, the Manager has
voluntarily undertaken to limit the "Total Annual Operating Expenses" for all
classes of shares so that "Total Annual Operating Expenses," as a percentage of
average daily net assets will not exceed the following annual rates: 0.90% for
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
August 31, 2006, the Manager reimbursed the Fund $953,104, $365,445, $193,081
and $110,748 for Class A, Class B, Class C and Class N shares, respectively. The
Manager may modify or terminate that undertaking at any time without notice to
shareholders.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class.
During the year ended August 31, 2006, OFS waived $30,636 for Class N shares.
This undertaking may be amended or withdrawn at any time.

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

5. FUTURES CONTRACTS Continued

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 at
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
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

As of August 31, 2006, the Fund had outstanding futures contracts as follows:

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) on the notional amount of the swap in an
amount equal to the daily change in such valuation. The Fund also records any
periodic payments received from (paid to) the counterparty, including at
termination, under such contracts as realized gain (loss).

      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, 2006, the Fund had no outstanding 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 unrealized gain (loss) related to the daily change
in the valuation of the notional amount of the swap, as well as the amount due
to (owed by) the Fund at termination or settlement, is combined and separately
disclosed as an asset (liability). The Fund also records any periodic payments
received from (paid to) the counterparty, including at termination, under such
contracts as realized gain (loss). Total return swaps are subject to risks (if
the counterparty fails to meet its obligations).

As of August 31, 2006, the Fund had entered into the following total return swap

8. ILLIQUID SECURITIES

As of August 31, 2006, 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
securities, letters of credit 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 each day. If the Fund is
undercollateralized at the close of business due to an increase in market value
of securities on loan, additional collateral is requested from the borrowing
counterparty and is delivered to the Fund on the next business day. Cash
collateral may be invested in approved investments and the Fund bears the risk
of any loss in value of these investments. The Fund retains a portion of the
interest earned from the collateral. 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. 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, 2006, the Fund had no securities on loan.

- --------------------------------------------------------------------------------
10. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Fund's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Fund's tax return will
be ultimately sustained. A tax liability and expense must be recorded in respect
of any tax position that, in Management's judgment, will not be fully realized.
FIN 48 is effective for fiscal years beginning after December 15, 2006. As of
August 31, 2006, the Manager is evaluating the implications of FIN 48. Its
impact in the Fund's financial statements has not yet been determined.

11. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds including the Fund) in the U.S. District Court for the
Southern District of New York on January 10, 2005 and was amended on March 4,
2005. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses.

      In response to the defendants' motions to dismiss the suit, seven of the
eight counts in the complaint, including the claims against certain of the
Oppenheimer funds, as nominal defendants, and against certain present and former
Directors, Trustees and Officers of the funds, and the Distributor, as
defendants, were dismissed with prejudice, by court order dated March 10, 2006,
and the remaining count against the Manager and the Transfer Agent was dismissed
with prejudice by court order dated April 5, 2006. The plaintiffs filed an
appeal of those dismissals on May 11, 2006.

      The Manager believes that the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, the funds, the
Directors/Trustees or the Officers on the appeal of the decisions of the
district court, 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, 2006, 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, 2006, 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, 2006, 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 2007, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2006. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      None of the dividends paid by the Fund during the fiscal year ended August
31, 2006 are eligible for the corporate dividend-received deduction.

      Dividends, if any, paid by the Fund during the fiscal year ended August
31, 2006 which are not designated as capital gain distributions, may be eligible
for lower individual income tax rates to the extent that the Fund has received
qualified dividend income as stipulated by recent tax legislation. In early
2007, shareholders of record will receive information regarding the percentage
of distributions that are eligible for lower individual income tax rates. The
amount will be the maximum amount allowed.

      Recent tax legislation allows a regulated investment company to designate
distributions not designated as capital gain distributions, as either interest
related dividends or short-term capital gain dividends, both of which are exempt
from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal
year ended August 31, 2006, $42,055,715 or 100% of the ordinary distributions
paid by the Fund qualifies as an interest related dividend.

      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.

      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 $83,000 in fiscal 2006 and $137,059 in fiscal
      2005 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 08/31/2006, 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.

(a)   (1)   Exhibit attached hereto.

      (2)   Exhibits attached hereto.

      (3)   Not applicable.

(b)   Exhibit attached hereto.
