ITEM 1. REPORTS TO STOCKHOLDERS.

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

FUND EXPENSES. As a shareholder of the Trust, you incur two types of costs: (1)
transaction costs, and redemption fees, if any; and (2) ongoing costs, including
management fees; distribution and service fees; and other Trust expenses. These
examples are intended to help you understand your ongoing costs (in dollars) of
investing in the Trust 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 December 31, 2004.

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, 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 Trust's actual expense ratio, and an assumed rate of
return of 5% per year before expenses, which is not the Trust'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 Trust and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads). 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.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 184/366 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended December 31, 2004 is as follows:

1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Government Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek a high level of current income that
is consistent with the preservation of capital and the maintenance of liquidity.
The Trust's investment advisor is Centennial Asset Management Corporation (the
Manager), a subsidiary of OppenheimerFunds, Inc. (OFI).

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern
time on each day The New York Stock Exchange (the Exchange) is open for trading.
Portfolio securities are valued on the basis of amortized cost, which
approximates market value.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Trust, 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.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Trust 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.

      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 Trust.

      As of December 31, 2004, the Trust had available for federal income tax
purposes an estimated capital loss carryforward of $2,933 expiring by 2013. This
estimated capital loss carryforward represents carryforward as of the end of the
last fiscal year, increased for losses deferred under tax accounting rules to
the current fiscal year and is increased or decreased by capital losses or gains
realized in the first six months of the current fiscal year. During the six
months ended December 31, 2004 and the fiscal year ended June 30, 2004, the
Trust did not utilize any capital loss carryforward.


                   12 | CENTENNIAL GOVERNMENT TRUST



As of June 30, 2004, the Trust had available for federal income tax purposes
post-October losses of $450 and unused capital loss carryforward as follows:

                       EXPIRING
                       ----------------------------
                       2012                $  2,557

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. 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 Trust. 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 Trust or in other Oppenheimer funds
selected by the Trustee. The Trust purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Trust 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 Trust, and will not materially affect the
Trust'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 but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
include interest expense incurred by the Trust 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 Trust 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 Trust 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.

ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      The registrant's Board of Trustees has established a Governance Committee,
one function of which is to create and oversee the process by which shareholders
can submit nominees for positions on the Board. The Governance Committee has not
yet adopted a charter, but anticipates that it will do so by the end of this
calendar year. The Committee has temporarily adopted the process previously
adopted by the Audit Committee regarding shareholder submission of nominees for
board positions. Shareholders may submit names of individuals, accompanied by
complete and properly supported resumes, for the Governance Committee's
consideration by mailing such information to the Committee in care of the Fund.
The Committee may consider such persons at such time as it meets to consider
possible nominees. The Committee, however, reserves solo discretion to determine
the candidates for trustees and independent trustees to recommend to the Board
and/or shareholders and may identify candidates other than those submitted by
Shareholders. The Committee may, but need not, consider the advice and
recommendation of the Manager and its affiliates in selecting nominees. The full
Board elects new trustees except for those instances when a shareholder vote is
required.

      Shareholders who desire to communicate with the Board should address
correspondence to the Board of Trustees of the registrant, or to an individual
Trustee c/o the Secretary of the Fund at 6803 South Tucson Way, Centennial,
Colorado 80112 and may submit their correspondence electronically at
WWW.OPPENHEIMERFUNDS.COM under the caption "contact us." If your correspondence
is intended for a particular Trustee, please indicate the name of the Trustee
for whom it is intended. The sender should indicate in the address whether it is
intended for the entire board, the Independent Trustees as group, or to an
individual Trustee. The Governance Committee will consider if a different
process should be recommended to the Board.



ITEM 10. CONTROLS AND PROCEDURES

      (a)   Based on their evaluation of 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 December 31, 2004,
            registrant's principal executive officer and principal financial
            officer found registrant's disclosure controls and procedures to
            provide reasonable assurances that information required to be
            disclosed by 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.

      (b)   There have been no changes in registrant's internal controls over
            financial reporting that occurred during the registrant's last
            fiscal quarter that has materially affected, or is reasonably likely
            to materially affect, the registrant's internal control over
            financial reporting.
