PORTFOLIO PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE PORTFOLIO PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS,
INC., OF THE PORTFOLIO'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JANUARY 31,
2007, FOLLOWED BY A GRAPHICAL COMPARISON OF THE PORTFOLIO'S PERFORMANCE TO AN
APPROPRIATE BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE. For the 12-month period ending
January 31, 2007, Conservative Investor Fund outperformed the Lehman Brothers
Aggregate Bond Index, but underperformed the S&P 500 Index. We attribute the
Portfolio's results to the outperformance of its allocation to alternative
investment funds, primarily its exposure to Oppenheimer Real Estate Fund's Class
Y shares. Portfolio performance was further strengthened by its allocation to
fixed-income funds, as most of these underlying funds posted strong returns and
outperformed their respective benchmarks. In contrast, the Portfolio's holdings
in Oppenheimer Commodity Strategy Total Return Fund's Class Y shares detracted
from results.

      During the reporting period, the Portfolio received significant positive
contributions to performance from its allocation to alternative investments,
primarily from its holdings in Oppenheimer Real Estate's Class Y shares.
Oppenheimer Real Estate Fund's Class Y shares posted a return of 38.55% (without
sales charge) and strongly outperformed its own benchmark. This strong
outperformance can be attributed to the Fund's profitable investments in the
office, apartment and industrial sectors. The Portfolio's underlying
fixed-income funds, which included Oppenheimer Core Bond Fund, Oppenheimer
Limited-Term Government Fund, Oppenheimer Champion Income Fund and Oppenheimer
International Bond Fund, posted strong results and significantly added to the
Portfolio's total return. The Portfolio's single largest holding at the end of
the period, Oppenheimer Core Bond Fund, benefited from multiple factors. Perhaps
the most significant contributor was it's positioning within the corporate bond
sector, an area of the fixed income market that posted double-digit returns.
Additionally, Oppenheimer Core Bond Fund benefited from its interest rate
positioning and its mortgage strategy. Oppenheimer Limited-Term Government Fund
greatly benefited from active management of its interest-rate sensitivity and
mortgage portfolio.

      The Portfolio's exposure to the high-yield bond market through its
allocation to Oppenheimer Champion Income Fund also contributed to performance.
Oppenheimer Champion Income, which produced competitive returns for the period,
received positive contributions to performance from a variety of higher-quality
issues across multiple market sectors. Lastly, the Portfolio's allocation to
Oppenheimer International Bond Fund added to returns. Over the period, this Fund
outperformed its Lipper peer group primarily due to its emphasis on bonds and
currencies from the emerging markets, which continued to gain value in a robust
global economy.


                         10 | CONSERVATIVE INVESTOR FUND



      On the negative side of performance, the largest detractor was the
Portfolio's allocation to Oppenheimer Commodity Strategy Total Return Fund,
which declined as a result of its natural gas and petroleum holdings. Over the
period, the price of oil eroded due to multiple factors that included an easing
of geopolitical tensions, rise in inventories and slowing demand. Additionally,
the unseasonably warm winter contributed to the natural gas price decline.

      The second area that disappointed was the Portfolio's allocation to equity
funds. Over the period, the investment climate proved quite volatile for equity
investors, especially for those that seek out high-quality companies with strong
long-term earnings growth prospects. Despite this difficult investing
environment, the Portfolio's underlying equity funds produced strong absolute
performance but most lagged their respective benchmarks.

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
Portfolio held until January 31, 2007. Performance is measured from the
inception of Classes A, B, C, N and Y on April 5, 2005. The Portfolio'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 Portfolio's performance is compared to the performance of the Lehman
Brothers Aggregate Bond Index and the S&P 500 Index. The Lehman Brothers
Aggregate Bond Index is an index of U.S. Government and corporate bonds that
includes reinvestment of interest. The index is unmanaged and cannot be
purchased directly by investors. Index performance is shown for illustrative
purposes only and does not predict or depict the performance of the Portfolio.
The S&P 500 Index is a broad-based measure of domestic stock performance that
includes the reinvestment of dividends. 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 Portfolio's
performance reflects the effects of the Portfolio's business and operating
expenses. While index comparisons may be useful to provide a benchmark for the
Portfolio's performance, it must be noted that the Portfolio's investments are
not limited to the investments in the index.

PORTFOLIO EXPENSES
- --------------------------------------------------------------------------------

PORTFOLIO EXPENSES. As a shareholder of the Portfolio, 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 Portfolio expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Portfolio 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 January 31, 2007.

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 Portfolio'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
Portfolio'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 Portfolio 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


                         19 | CONSERVATIVE INVESTOR FUND



PORTFOLIO EXPENSES
- --------------------------------------------------------------------------------

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            1,025.00         0.20

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Portfolio'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,
excluding all underlying fund expenses, based on the 6-month period ended
January 31, 2007 are as follows:

CLASS       EXPENSE RATIOS
- ----------------------------
Class A          0.38%
- ----------------------------
Class B          1.24
- ----------------------------
Class C          1.19
- ----------------------------
Class N          0.65
- ----------------------------
Class Y          0.04

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

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Portfolio Series (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
Conservative Investor Fund (the "Portfolio") is a series of the Fund whose
investment objective is to seek current income with a secondary objective of
long-term growth of capital. The Portfolio is a special type of mutual fund
known as a "fund of funds" because it invests in other mutual funds. The
Portfolio normally invests in a portfolio consisting of a target weighted
allocation in Class A or Class Y shares of other Oppenheimer funds. The Fund's
investment advisor is OppenheimerFunds, Inc. (the "Manager").

      The Portfolio 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 Portfolio 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.

      Under normal market conditions, the Manager will invest the Portfolio's
assets in shares of Oppenheimer Core Bond Fund, Oppenheimer Capital Appreciation
Fund, Oppenheimer Champion Income Fund, Oppenheimer Global Fund, Oppenheimer
International Bond Fund, Oppenheimer Limited-Term Government Fund, Oppenheimer
Main Street Fund(R), Oppenheimer Commodity Strategy Total Return Fund(R),
Oppenheimer Real Estate Fund, Oppenheimer Value Fund and Oppenheimer
Institutional Money Market Fund (individually, an "Underlying Fund" and
collectively, the "Underlying Funds").

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Portfolio calculates the net asset value of each class
of shares based upon the net asset value of the applicable Underlying Fund 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 trading. For each Underlying
Fund, the net asset value per share for a class of shares on a "regular business
day" is determined by dividing the value of the Underlying Fund's net assets
attributable to that class by the number of shares of that class outstanding on
that day. To determine net asset values, the Underlying Fund assets


                         32 | CONSERVATIVE INVESTOR FUND



are valued primarily on the basis of current market quotations. If market
quotations are not readily available or do not accurately reflect fair value for
a security (in the Manager's judgment) or if a security's value has been
materially affected by events occurring after the close of the exchange or
market on which the security is principally traded, that security may be valued
by another method that the Underlying Fund's Board of Trustees/ Directors
believes accurately reflects the fair value. Because some foreign securities
trade in markets and on exchanges that operate on weekends and U.S. holidays,
the values of some of the Underlying Fund's foreign investments may change on
days when investors cannot buy or redeem Underlying Fund shares.

      Short-term "money market type" debt securities with remaining maturities
of sixty days or less are valued at amortized cost (which approximates market
value).

- --------------------------------------------------------------------------------
RISKS OF INVESTING IN THE UNDERLYING FUNDS. Each of the Underlying Funds in
which the Portfolio invests has its own investment risks, and those risks can
affect the value of the Portfolio's investments and therefore the value of the
Portfolio's shares. To the extent that the Portfolio invests more of its assets
in one Underlying Fund than in another, the Portfolio will have greater exposure
to the risks of that Underlying Fund.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Portfolio is
permitted to invest daily available cash balances in an affiliated money market
fund. The Portfolio may invest the available cash in Class E shares of
Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current income
and stability of principal. IMMF is a registered open-end management investment
company, regulated as a money market fund under the Investment Company Act of
1940, as amended. The Manager is also the investment advisor of IMMF. The
Portfolio's investment in IMMF is included in the Statement of Investments. As a
shareholder, the Portfolio is subject to its proportional share of IMMF's Class
E expenses, including its management fee. The Manager will waive fees and/or
reimburse Portfolio expenses in an amount equal to the indirect management fees
incurred through the Portfolio's investment in IMMF.

- --------------------------------------------------------------------------------
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 Portfolio 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 Portfolio must satisfy under the income tax
regulations, losses the Portfolio may be able to offset against income and gains
realized in future years and

1. During the fiscal year ended January 31, 2007, the Portfolio did not utilize
any capital loss carryforward.

2. During the fiscal year ended January 31, 2006, the Portfolio 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 Portfolio.
Accordingly, the following amounts have been reclassified for January 31, 2007.
Net assets of the Portfolio were unaffected by the reclassifications.

TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
(the "Plan") for the Portfolio's independent trustees. Benefits are based on
years of service and fees paid to each trustee during their period of service.
The Plan was frozen with respect to adding new participants effective December
31, 2006 (the "Freeze Date") and existing Plan Participants as of the Freeze
Date will continue to receive accrued benefits under the Plan. Active
independent trustees as of the Freeze Date have each elected a distribution
method with respect to their benefits under the Plan. During the year ended
January 31, 2007, the Portfolio's projected benefit obligations were increased
by $9,986 and payments of $251 were made to retired trustees, resulting in an
accumulated liability of $9,735 as of January 31, 2007.

      The Board of Trustees has adopted a compensation deferral 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
Portfolio. 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 Portfolio or in other Oppenheimer funds selected by
the Trustee. The Portfolio purchases shares of the funds selected for deferral
by the Trustee in amounts equal to his or her deemed investment, resulting in a
Portfolio 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 Portfolio, and will not materially affect the
Portfolio's assets, liabilities or net investment income per share. Amounts will
be deferred until distributed in accordance to the compensation deferral 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 and 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 Portfolio 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 share

holder redemption activity. The Portfolio pays interest to its custodian on such
cash overdrafts, to the extent they are not offset by positive cash balances
maintained by the Portfolio, 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 Portfolio 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 Portfolio'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 Portfolio. In
the normal course of business, the Portfolio may also enter into contracts that
provide general indemnifications. The Portfolio's maximum exposure under these
arrangements is unknown as this would be dependent on future claims that may be
made against the Portfolio. 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.

the Portfolio for the year ended January 31, 2007 was 0.54%.

      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.

- --------------------------------------------------------------------------------
OFFERING AND ORGANIZATIONAL COSTS. The Manager paid all offering and
organizational costs associated with the registration and seeding of the
Portfolio.

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

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Portfolio 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 Portfolio. 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
Portfolio under the plan are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The
Portfolio 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
Portfolio 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 Portfolio 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 Portfolio 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
determines its uncompensated expenses under the plan at calendar quarter ends.
The Distributor's aggregate uncompensated expenses under the plan at December
31, 2006 for Class B, Class C and Class N shares were $339,811, $335,871 and
$216,428, respectively. Fees incurred by the Portfolio 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 Portfolio. They are deducted from the
proceeds of sales of Portfolio 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 CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Manager has voluntarily agreed to a
total expense limitation on the aggregate amount of combined direct
(fund-of-funds level) and indirect expense so that "Total expenses" as a
percentage of average daily net assets will not exceed the following annual
rates: 1.25%, 2.00%, 2.00%, 1.50% and 1.00%, for Class A, Class B, Class C,
Class N and Class Y, respectively. The Manager may modify or terminate this
undertaking at any time without notice to shareholders. These expense
limitations do not include Extraordinary Expenses and other expenses not
incurred in the ordinary course of the Portfolio's business. Notwithstanding the
foregoing limits, the Manager is not required to waive or reimburse Portfolio
expenses in excess of indirect management fees earned from investments in
Underlying Funds to assure that expenses do not exceed those limits.

      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. This
undertaking may be amended or withdrawn at any time.

      The Manager will waive fees and/or reimburse Portfolio expenses in an
amount equal to the indirect management fees incurred through the Portfolio's
investment in IMMF. During the year ended January 31, 2007, the Manager waived
$81 for IMMF management fees.

5. RECENT ACCOUNTING PRONOUNCEMENTS

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 Portfolio's tax returns to determine
whether it is "more-likely-than-not" that tax positions taken in the Portfolio's
tax return will be ultimately sustained. A tax liability and expense must be
recorded in

5. RECENT ACCOUNTING PRONOUNCEMENTS Continued

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 January 31, 2007, the Manager has evaluated the implications of FIN
48 and does not currently anticipate a material impact to the Portfolio's
financial statements. The Manager will continue to monitor the Portfolio's tax
positions prospectively for potential future impacts.

      In September 2006, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of January 31, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

- --------------------------------------------------------------------------------
6. 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 excluding the Portfolio) 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.

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER PORTFOLIO SERIES:

We have audited the accompanying statement of assets and liabilities of
Conservative Investor Fund (one of the portfolios constituting the Oppenheimer
Portfolio Series), including the statement of investments, as of January 31,
2007, the related statement of operations for the year then ended, and the
statements of changes in net assets and the financial highlights for the year
then ended and for the period April 5, 2005 (commencement of operations) to
January 31, 2006. These financial statements and financial highlights are the
responsibility of the Portfolio'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 January 31, 2007, 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
Conservative Investor Fund as of January 31, 2007, the results of its operations
for the year then ended, and the changes in its net assets and the financial
highlights for the year then ended and for the period April 5, 2005
(commencement of operations) to January 31, 2006, in conformity with U.S.
generally accepted accounting principles.

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

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Portfolio during
calendar year 2006. Regulations of the U.S. Treasury Department require the
Portfolio to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.017 per share were paid to Class A, Class
B, Class C, Class N and Class Y shareholders, respectively, on December 29,
2006. 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).

      Dividends, if any, paid by the Portfolio during the fiscal year ended
January 31, 2007 which are not designated as capital gain distributions should
be multiplied by 5.84% to arrive at the amount eligible for the corporate
dividend-received deduction.

      A portion, if any, of the dividends paid by the Portfolio during the
fiscal year ended January 31, 2007 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Portfolio has received qualified dividend income as stipulated by
recent tax legislation. $486,335 of the Portfolio's fiscal year taxable income
may be eligible for the lower individual income tax rates. In early 2007,
shareholders of record received information regarding the percentage of
distributions that are eligible for lower individual income tax rates.

      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 January 31, 2007, $23,416 or 0.45% of the ordinary distributions paid
by the Portfolio qualifies as an interest related dividend.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Portfolio 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 PORTFOLIO'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
investment advisory agreement (the "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 Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information about the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel who provide such services. The Manager's duties
include providing the Fund with the services of the portfolio managers and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.


                         44 | CONSERVATIVE INVESTOR FUND



      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 took account of the fact 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 has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Rudi
Schadt, Jerry Webman and Kurt Wolfgruber, the members of the Fund's Asset
Allocation Team. The Board members also considered their experiences with the
Manager and its officers and other personnel through their service on the boards
of the Fund and other funds advised by the Manager. The Board considered
information regarding the quality of services provided by affiliates of the
Manager, which its members have become knowledgeable about in connection with
the renewal of the Fund's service agreements. In light of the foregoing, the
Board concluded that the Fund benefits from the services provided under the
Agreement and from the Manager's experience, reputation, personnel, operations,
and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
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 all other retail front-end load and
no-load conservative mixed-asset target allocation funds advised by other
investment advisers. The Board noted that the Fund's one-year and since
inception performance were better than its peer group median.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to the fees and services for other clients or accounts advised by
the Manager. The independent consultant provided comparative data in regard to
the fees and expenses of the Fund, other mixed-asset target allocation
conservative funds of funds and other funds with comparable asset levels and
distribution features. The Board noted that the Manager has agreed to
voluntarily limit the aggregate amount of combined direct (fund-of-funds level)
and indirect expenses so that total annual portfolio and underlying fund
operating expenses as a percentage of average daily net assets will not exceed
the following annual rates:

1.25% for Class A, 2.00% for Class B, 2.00% for Class C, 1.50% for Class N and
1.00% for Class Y. The Manager may modify or terminate that undertaking at any
time without notice to shareholders. The Board noted that the Fund does not pay
a management fee and that the Fund's total expenses are equal to its peer group
median.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Fund, the extent to which
those economies of scale would benefit the Fund's shareholders and the current
level of Fund assets.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. 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 to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided.

      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 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 are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the 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 Agreement,
including the management fee, in light of all of the surrounding circumstances.

PORTFOLIO PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE PORTFOLIO PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS,
INC., OF THE PORTFOLIO'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JANUARY 31,
2007, FOLLOWED BY A GRAPHICAL COMPARISON OF THE PORTFOLIO'S PERFORMANCE TO AN
APPROPRIATE BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. For the 12-month period ending
January 31, 2007, Moderate Investor Fund significantly outperformed its
fixed-income benchmark, the Lehman Brothers Aggregate Bond Index, but
underperformed its equity benchmark, the S&P 500 Index. We attribute the
Portfolio's positive results to the outperformance of its alternative investment
funds, primarily its exposure to Oppenheimer Real Estate Fund's Class Y shares.
Portfolio performance was further strengthened by its allocation to fixed-income
funds, as most of these underlying funds posted strong returns and outperformed
their respective benchmarks.

      In contrast, the Portfolio's exposure to commodities through its
allocation to the Oppenheimer Commodity Strategy Total Return Fund was the
greatest detractor from results. Additionally, although the Portfolio's
underlying equity funds produced strong absolute returns, which boosted
Portfolio performance, a majority of them lagged in terms of relative
performance to their respective benchmarks

      On the alternative investments side, the Portfolio's position in
Oppenheimer Real Estate Fund's Class Y shares at period end, which posted
impressive returns and strongly outperformed its own benchmark, was a boon to
the Portfolio's performance. Oppenheimer Real Estate Fund's success can be
attributed, in part, to the Fund's profitable investments in the office,
apartment and industrial sectors.

      The Portfolio also benefited from its allocation to fixed-income funds, as
the majority of these funds produced both strong absolute and relative returns.
The Portfolio's single largest holding at period end, Oppenheimer Core Bond
Fund, outperformed due to multiple factors. Perhaps the most significant
contributor was its positioning within the corporate bond sector, an area of the
fixed-income market that posted double-digit returns. Oppenheimer Limited-Term
Government Fund added to the Portfolio's returns as it benefited from active
management of its interest-rate sensitivity and mortgage portfolio. The
Portfolio's exposure to the high yield bond market, through its allocation to
Oppenheimer Champion Income Fund also contributed to performance. The Portfolio
also benefited from its allocation to Oppenheimer International Bond Fund's
Class Y shares, as this Fund outperformed its Lipper peer group primarily due to
its emphasis on bonds and currencies from the emerging markets.

      On the equity side, the strong absolute gains generated by the Portfolio's
underlying funds were not enough to overcome the negative affects of many of
these funds weak relative gains, a situation that ultimately hampered the
Portfolio's total returns. For example,


                           10 | MODERATE INVESTOR FUND



the Portfolio gained from its holdings in Oppenheimer Global Fund and
Oppenheimer Main Street Fund, but both funds lagged behind their respective
benchmarks. An exception was Oppenheimer Value Fund's Class Y shares (also the
Fund's second largest holding at period end), which posted a strong total return
and outpaced its benchmark, the S&P 500 Index. The underperformance of several
of the Portfolio's equity funds can be attributed to a variety of factors, which
included the continued underperformance of growth stocks versus value stocks and
disappointing stock selection. Additionally, over the last 12-months the market
tended to not appropriately reward companies that consistently grew their
earnings. This situation ended up hurting some of the Portfolio's underlying
equity funds, as their investment philosophies tend to emphasize strong earnings
growth.

      Lastly, the Portfolio's exposure to commodities through its allocation to
the Oppenheimer Commodity Strategy Total Return Fund was the largest detractor
from results. Over the period, oil prices were quite volatile, ranging from $65
to a mid-summer high of close to $80 per barrel then dropping precipitously to
around $55 by period end. This volatility and ultimate price erosion is a result
of multiple factors that included an easing of geopolitical tensions, a rise in
inventories and a slowing demand. Additionally, an unseasonably warm winter
contributed to the natural gas price decline.

COMPARING THE PORTFOLIO'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 Portfolio held until January 31, 2007. Performance is measured from the
inception of Classes A, B, C, N and Y on April 5, 2005. The Portfolio'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 Portfolio's performance is compared to the performance of the S&P 500
Index and the Lehman Brothers Aggregate Bond Index. The S&P 500 Index is a
broad-based measure of domestic stock performance that includes the reinvestment
of dividends. The Lehman Brothers Aggregate Bond Index is an index of U.S.
Government and corporate bonds that includes reinvestment of dividends. 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 Portfolio's performance reflects the effects of the Portfolio's
business and operating expenses. While index comparisons may be useful to
provide a benchmark for the Portfolio's performance, it must be noted that the
Portfolio'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 Portfolio'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 Portfolio or any gains you may realize if you sell your shares.

INVESTORS SHOULD CONSIDER THE PORTFOLIO'S INVESTMENT OBJECTIVES, RISKS, AND
OTHER CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE PORTFOLIO'S
PROSPECTUS CONTAINS THIS AND OTHER INFORMATION ABOUT THE PORTFOLIO, 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.

PORTFOLIO EXPENSES
- --------------------------------------------------------------------------------

PORTFOLIO EXPENSES. As a shareholder of the Portfolio, 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 Portfolio expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Portfolio 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 January 31, 2007.

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 Portfolio'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
Portfolio'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 Portfolio 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 | MODERATE INVESTOR FUND



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.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Portfolio'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,
excluding all underlying fund expenses, based on the 6-month period ended
January 31, 2007 are as follows

CLASS     EXPENSE RATIOS
- ------------------------
Class A       0.41%
- ------------------------
Class B       1.22
- ------------------------
Class C       1.18
- ------------------------
Class N       0.66
- ------------------------
Class Y       0.00

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

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Portfolio Series (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
Moderate Investor Fund (the "Portfolio") is a series of the Fund whose
investment objective is to seek long term growth of capital and current income.
The Portfolio is a special type of mutual fund known as a "fund of funds"
because it invests in other mutual funds. The Portfolio normally invests in a
portfolio consisting of a target-weighted allocation in Class A or Class Y
shares of other Oppenheimer funds. The Fund's investment advisor is
OppenheimerFunds, Inc. (the "Manager").

      The Portfolio 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 Portfolio 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.

      Under normal market conditions, the Manager will invest the Portfolio's
assets in shares of Oppenheimer Core Bond Fund, Oppenheimer Capital Appreciation
Fund, Oppenheimer Champion Income Fund, Oppenheimer Global Fund, Oppenheimer
International Bond Fund, Oppenheimer Limited-Term Government Fund, Oppenheimer
Main Street Fund(R), Oppenheimer Main Street Opportunity Fund(R), Oppenheimer
Commodity Strategy Total Return Fund(R), Oppenheimer Real Estate Fund,
Oppenheimer Value Fund and Oppenheimer Institutional Money Market Fund
(individually, an "Underlying Fund" and collectively, the "Underlying Funds").

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Portfolio calculates the net asset value of each class
of shares based upon the net asset value of the applicable Underlying Fund 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 trading. For each Underlying
Fund, the net asset value per share for a class of shares on a "regular business
day" is determined by dividing the value of the Underlying Fund's net assets
attributable to that class by the number of shares of that


                           31 | MODERATE INVESTOR FUND



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

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

class outstanding on that day. To determine net asset values, the Underlying
Fund assets are valued primarily on the basis of current market quotations. If
market quotations are not readily available or do not accurately reflect fair
value for a security (in the Manager's judgment) or if a security's value has
been materially affected by events occurring after the close of the exchange or
market on which the security is principally traded, that security may be valued
by another method that the Underlying Fund's Board of Trustees/Directors
believes accurately reflects the fair value. Because some foreign securities
trade in markets and on exchanges that operate on weekends and U.S. holidays,
the values of some of the Underlying Fund's foreign investments may change on
days when investors cannot buy or redeem Underlying Fund shares.

      Short-term "money market type" debt securities with remaining maturities
of sixty days or less are valued at amortized cost (which approximates market
value).

- --------------------------------------------------------------------------------
RISKS OF INVESTING IN THE UNDERLYING FUNDS. Each of the Underlying Funds in
which the Portfolio invests has its own investment risks, and those risks can
affect the value of the Portfolio's investments and therefore the value of the
Portfolio's shares. To the extent that the Portfolio invests more of its assets
in one Underlying Fund than in another, the Portfolio will have greater exposure
to the risks of that Underlying Fund.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Portfolio is
permitted to invest daily available cash balances in an affiliated money market
fund. The Portfolio may invest the available cash in Class E shares of
Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current income
and stability of principal. IMMF is a registered open-end management investment
company, regulated as a money market fund under the Investment Company Act of
1940, as amended. The Manager is also the investment advisor of IMMF. The
Portfolio's investment in IMMF is included in the Statement of Investments. As a
shareholder, the Portfolio is subject to its proportional share of IMMF's Class
E expenses, including its management fee. The Manager will waive fees and/or
reimburse Portfolio expenses in an amount equal to the indirect management fees
incurred through the Portfolio's investment in IMMF.

- --------------------------------------------------------------------------------
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 Portfolio 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.


                           32 | MODERATE INVESTOR FUND



The tax components of capital shown in the table below represent distribution
requirements the Portfolio must satisfy under the income tax regulations, losses
the Portfolio 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. During the fiscal year ended January 31, 2007, the Portfolio did not utilize
any capital loss carryforward.

2. During the fiscal year ended January 31, 2006, the Portfolio 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 Portfolio.
Accordingly, the following amounts have been reclassified for January 31, 2007.
Net assets of the Portfolio were unaffected by the reclassifications.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
(the "Plan") for the Portfolio's independent trustees. Benefits are based on
years of service and fees paid to each trustee during their period of service.
The Plan was frozen with respect to adding new participants effective December
31, 2006 (the "Freeze Date") and existing Plan Participants as of the Freeze
Date will continue to receive accrued benefits under the Plan. Active
independent trustees as of the Freeze Date have each elected a distribution
method with respect to their benefits under the Plan. During the year ended
January 31, 2007, the Portfolio's projected benefit obligations were increased
by $27,088 and payments of $689 were made to retired trustees, resulting in an
accumulated liability of $26,399 as of January 31, 2007.

      The Board of Trustees has adopted a compensation deferral 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
Portfolio. 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 Portfolio or in other Oppenheimer funds selected by
the Trustee. The Portfolio purchases shares of the funds selected for deferral
by the Trustee in amounts equal to his or her deemed investment, resulting in a
Portfolio 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 Portfolio, and will not materially affect the
Portfolio's assets, liabilities or net investment income per share. Amounts will
be deferred until distributed in accordance to the compensation deferral 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 and 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.


                           34 | MODERATE INVESTOR FUND



- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Portfolio 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 Portfolio pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Portfolio, 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
Portfolio 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 Portfolio'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 Portfolio. In
the normal course of business, the Portfolio may also enter into contracts that
provide general indemnifications. The Portfolio's maximum exposure under these
arrangements is unknown as this would be dependent on future claims that may be
made against the Portfolio. 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.

charge a management fee, but rather collects indirect management fees from
investments in the Underlying Funds. The weighted indirect management fees
collected from the Underlying Funds, as a percent of average daily net assets of
the Portfolio for the year ended January 31, 2007 was 0.56%.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS or the Transfer Agent), a
division of the Manager, acts as the transfer and shareholder servicing agent
for the Portfolio. The Portfolio pays OFS a per account fee. For the year ended
January 31, 2007, the Portfolio paid $433,544 to OFS for services to the
Portfolio.


                           36 | MODERATE INVESTOR 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.

- --------------------------------------------------------------------------------
OFFERING AND ORGANIZATIONAL COSTS. The Manager paid all offering and
organizational costs associated with the registration and seeding of the
Portfolio.

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

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Portfolio 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 Portfolio. 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
Portfolio under the plan are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The
Portfolio 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
Portfolio 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 Portfolio 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 Portfolio 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
determines its uncompensated expenses under the plan at calendar quarter ends.
The Distributor's aggregate uncompensated expenses under the plan at December
31, 2006 for Class B, Class C and Class N shares were $1,467,225, $952,601 and
$434,332, respectively. Fees incurred by the Portfolio 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 Portfolio. They are deducted from the
proceeds of sales of Portfolio 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. The Manager has voluntarily agreed to a
total expense limitation on the aggregate amount of combined direct
(fund-of-funds level) and indirect expense so that "Total expenses" as a
percentage of average daily net assets will not exceed the following annual
rates: 1.30%, 2.05%, 2.05%, 1.55% and 1.05%, for Class A, Class B, Class C,
Class N and Class Y, respectively. The Manager may modify or terminate this
undertaking at any time without notice to shareholders. These expense
limitations do not include Extraordinary Expenses and other expenses not
incurred in the ordinary course of the Portfolio's business. Notwithstanding the
foregoing limits, the Manager is not required to waive or reimburse Portfolio
expenses in excess of indirect management fees earned from investments in
Underlying Funds to assure that expenses do not exceed those limits.

      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. This
undertaking may be amended or withdrawn at any time.

      The Manager will waive fees and/or reimburse Portfolio expenses in an
amount equal to the indirect management fees incurred through the Portfolio's
investment in IMMF. During the year ended January 31, 2007, the Manager waived
$346 for IMMF management fees.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENTS

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 Portfolio's tax returns to determine
whether it is "more-likely-than-not" that tax positions taken in the Portfolio'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 January 31, 2007, the Manager has evaluated the implications of
FIN 48 and does not currently anticipate a material impact to the Portfolio's
financial statements. The Manager will continue to monitor the Portfolio's tax
positions prospectively for potential future impacts.


                           38 | MODERATE INVESTOR FUND



      In September 2006, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of January 31, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

- --------------------------------------------------------------------------------
6. 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 excluding the Portfolio) 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 PORTFOLIO SERIES:

We have audited the accompanying statement of assets and liabilities of Moderate
Investor Fund (one of the portfolios constituting the Oppenheimer Portfolio
Series), including the statement of investments, as of January 31, 2007, the
related statement of operations for the year then ended, and the statements of
changes in net assets and the financial highlights for the year then ended and
for the period April 5, 2005 (commencement of operations) to January 31, 2006.
These financial statements and financial highlights are the responsibility of
the Portfolio'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 January 31, 2007, 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
Moderate Investor Fund as of January 31, 2007, the results of its operations for
the year then ended, and the changes in its net assets and the financial
highlights for the year then ended and for the period April 5, 2005
(commencement of operations) to January 31, 2006, in conformity with U.S.
generally accepted accounting principles.

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

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Portfolio during
calendar year 2006. Regulations of the U.S. Treasury Department require the
Portfolio to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.0274 per share were paid to Class A,
Class B, Class C, Class N and Class Y shareholders, respectively, on December
29, 2006. 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).

      Dividends, if any, paid by the Portfolio during the fiscal year ended
January 31, 2007 which are not designated as capital gain distributions should
be multiplied by 15.57% to arrive at the amount eligible for the corporate
dividend-received deduction.

      A portion, if any, of the dividends paid by the Portfolio during the
fiscal year ended January 31, 2007 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Portfolio has received qualified dividend income as stipulated by
recent tax legislation. $2,886,157 of the Portfolio's fiscal year taxable income
may be eligible for the lower individual income tax rates. In early 2007,
shareholders of record received information regarding the percentage of
distributions that are eligible for lower individual income tax rates.

      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 January 31, 2007, $54,916 or 0.45% of the ordinary distributions paid
by the Portfolio qualifies as an interest related dividend.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Portfolio 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 PORTFOLIO'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
investment advisory agreement (the "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 Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information about the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel who provide such services. The Manager's duties
include providing the Fund with the services of the portfolio managers and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.

BOARD APPROVAL OF THE PORTFOLIO'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued
- --------------------------------------------------------------------------------

      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 took account of the fact 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 has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Rudi
Schadt, Jerry Webman and Kurt Wolfgruber, the members of the Fund's Asset
Allocation Team. The Board members also considered their experiences with the
Manager and its officers and other personnel through their service on the boards
of the Fund and other funds advised by the Manager. The Board considered
information regarding the quality of services provided by affiliates of the
Manager, which its members have become knowledgeable about in connection with
the renewal of the Fund's service agreements. In light of the foregoing, the
Board concluded that the Fund benefits from the services provided under the
Agreement and from the Manager's experience, reputation, personnel, operations,
and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
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 all other retail front-end load and
no-load mixed-asset target allocation moderate funds advised by other investment
advisers. The Board noted that the Fund's one-year and since inception
performance were better than its peer group median.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to the fees and services for other clients or accounts advised by
the Manager. The independent consultant provided comparative data in regard to
the fees and expenses of the Fund, other moderate mixed-asset target allocation
funds of funds and other funds with comparable asset levels and distribution
features. The Board noted that the Manager has agreed to voluntarily limit the
aggregate amount of combined direct (fund-of-funds level) and indirect expenses
so that total annual portfolio and underlying fund operating expenses as a
percentage of average daily net assets will not exceed the following annual
rates: 1.30% for Class A, 2.05% for Class B and Class C, 1.55% for Class N and
1.05% for Class Y. The


                           44 | MODERATE INVESTOR FUND



Manager may modify or terminate that undertaking at any time without notice to
shareholders. The Board noted that the Fund does not pay a management fee and
that the Fund's total expenses are lower than its peer group median.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Fund, the extent to which
those economies of scale would benefit the Fund's shareholders and the current
level of Fund assets.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. 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 to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided.

      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 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 are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the 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 Agreement,
including the management fee, in light of all of the surrounding circumstances.

PORTFOLIO PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE PORTFOLIO PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS,
INC., OF THE PORTFOLIO'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JANUARY 31,
2007, FOLLOWED BY A GRAPHICAL COMPARISON OF THE PORTFOLIO'S PERFORMANCE TO AN
APPROPRIATE BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE. For its fiscal year ending
January 31, 2007, Equity Investor Fund's Class A shares, without sales charge,
returned 10.85% and under-performed its benchmark, the S&P 500 Index, which
returned 14.53%. We attribute this relative underperformance to the cumulative
underperformance of the Portfolio's underlying funds relative to their
respective benchmarks. In terms of individual detractors on a fund level, such
factors included volatile global equity markets and disappointing stock
selection within the Portfolio's underlying funds. Additionally, over the last
12-months, the global market tended to not appropriately reward high-quality
companies that consistently grew their earnings. This situation ended up hurting
many of the Portfolio's underlying funds, as their investment philosophies tend
to emphasize strong earnings growth.

      Despite the Portfolio's relative underperformance, its absolute
performance was favorable. Strong contributions made by three out of the
Portfolio's top five allocations helped Portfolio performance. Oppenheimer
Global Fund (the Portfolio's largest holding), Oppenheimer Value Fund and
Oppenheimer Main Street Fund all boosted Portfolio returns. The strong
performance of those Funds can be attributed to successful security selection.
An additional positive contributor was the Oppenheimer Developing Markets Fund.

      Among the top performance detractors to the Portfolio were the Oppenheimer
Capital Appreciation Fund (the Portfolio's second largest holding) and the
Oppenheimer Global Opportunities Fund. While the Oppenheimer Capital
Appreciation Fund was partially hurt by its exposure to the underperforming US
growth stock sector, the Oppenheimer Global Opportunities Fund experienced
disappointing returns due to both asset allocation and stock selection issues.

COMPARING THE PORTFOLIO'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 Portfolio held until January 31, 2007. Performance is measured from the
inception of Classes A, B, C, N and Y on April 5, 2005. The Portfolio'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 Portfolio's performance is compared to the performance of the S&P 500
Index. The S&P 500 Index is an unmanaged index of equity securities. Index
performance reflects the reinvestment of income but does not consider the effect
of transaction costs, and


                            9 | EQUITY INVESTOR FUND



PORTFOLIO PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

none of the data in the graphs shows the effect of taxes. The Portfolio s
performance reflects the effects of the Portfolio's business and operating
expenses. While index comparisons may be useful to provide a benchmark for the
Portfolio's performance, it must be noted that the Portfolio'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 Portfolio'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 Portfolio or any gains you may realize if you sell your shares.

INVESTORS SHOULD CONSIDER THE PORTFOLIO'S INVESTMENT OBJECTIVES, RISKS, AND
OTHER CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE PORTFOLIO'S

VISITING OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS CAREFULLY

PORTFOLIO EXPENSES
- --------------------------------------------------------------------------------

PORTFOLIO EXPENSES. As a shareholder of the Portfolio, 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 Portfolio expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Portfolio 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 January 31, 2007.

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 Portfolio'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
Portfolio'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 Portfolio 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


                            17 | EQUITY INVESTOR FUND



PORTFOLIO EXPENSES

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      1,025.10      0.10

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Portfolio'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,
excluding all underlying fund expenses, based on the 6-month period ended
January 31, 2007 are as follows:

CLASS     EXPENSE RATIOS
- ------------------------
Class A       0.50%
- ------------------------
Class B       1.30
- ------------------------
Class C       1.28
- ------------------------
Class N       0.67
- ------------------------
Class Y       0.02

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

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Portfolio Series (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
Equity Investor Fund formerly known as Aggressive Investor Fund (the
"Portfolio") is a series of the Fund whose investment objective is to seek long
term growth of capital. The Portfolio is a special type of mutual fund known as
a "fund of funds" because it invests in other mutual funds. The Portfolio
normally invests in a portfolio consisting of a target-weighted allocation in
Class A or Class Y shares of other Oppenheimer funds. The Fund's investment
advisor is OppenheimerFunds, Inc. (the "Manager").

      The Portfolio 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 Portfolio 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.

      Under normal market conditions, the Manager will invest the Portfolio's
assets in shares of Oppenheimer Capital Appreciation Fund, Oppenheimer
Developing Markets Fund, Oppenheimer Global Fund, Oppenheimer Global
Opportunities Fund, Oppenheimer Main Street Fund(R), Oppenheimer Main Street
Opportunity Fund(R), Oppenheimer Main Street Small Cap Fund(R), Oppenheimer
Value Fund and Oppenheimer Institutional Money Market Fund (individually, an
"Underlying Fund" and collectively, the "Underlying Funds").

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Portfolio calculates the net asset value of each class
of shares based upon the net asset value of the applicable Underlying Fund 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 trading. For each Underlying
Fund, the net asset value per share for a class of shares on a "regular business
day" is determined by dividing the value of the Underlying Fund's net assets
attributable to that class by the number of shares of that class outstanding on
that day. To determine net asset values, the Underlying Fund assets


                           30 | EQUITY INVESTOR FUND



are valued primarily on the basis of current market quotations. If market
quotations are not readily available or do not accurately reflect fair value for
a security (in the Manager's judgment) or if a security's value has been
materially affected by events occurring after the close of the exchange or
market on which the security is principally traded, that security may be valued
by another method that the Underlying Fund's Board of Trustees/Directors
believes accurately reflects the fair value. Because some foreign securities
trade in markets and on exchanges that operate on weekends and U.S. holidays,
the values of some of the Underlying Fund's foreign investments may change on
days when investors cannot buy or redeem Underlying Fund shares.

      Short-term "money market type" debt securities with remaining maturities
of sixty days or less are valued at amortized cost (which approximates market
value).

- --------------------------------------------------------------------------------
RISKS OF INVESTING IN THE UNDERLYING FUNDS. Each of the Underlying Funds
in which the Portfolio invests has its own investment risks, and those risks can
affect the value of the Portfolio's investments and therefore the value of the
Portfolio's shares. To the extent that the Portfolio invests more of its assets
in one Underlying Fund than in another, the Portfolio will have greater exposure
to the risks of that Underlying Fund.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Portfolio is
permitted to invest daily available cash balances in an affiliated money market
fund. The Portfolio may invest the available cash in Class E shares of
Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current income
and stability of principal. IMMF is a registered open-end management investment
company, regulated as a money market fund under the Investment Company Act of
1940, as amended. The Manager is also the investment advisor of IMMF. The
Portfolio's investment in IMMF is included in the Statement of Investments. As a
shareholder, the Portfolio is subject to its proportional share of IMMF's Class
E expenses, including its management fee. The Manager will waive fees and/or
reimburse Portfolio expenses in an amount equal to the indirect management fees
incurred through the Portfolio's investment in IMMF.

- --------------------------------------------------------------------------------
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 Portfolio 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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

The tax components of capital shown in the table below represent distribution
requirements the Portfolio must satisfy under the income tax regulations, losses
the Portfolio 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 UNREALIZED

1. During the fiscal year ended January 31, 2007, the Portfolio did not utilize
any capital loss carryforward.

2. During the fiscal year ended January 31, 2006, the Portfolio 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 Portfolio.
Accordingly, the following amounts have been reclassified for January 31, 2007.
Net assets of the Portfolio were unaffected by the reclassifications.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of January 31, 2007 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is


                            32 | EQUITY INVESTOR FUND

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
(the "Plan") for the Portfolio's independent trustees. Benefits are based on
years of service and fees paid to each trustee during their period of service.
The Plan was frozen with respect to adding new participants effective December
31, 2006 (the "Freeze Date") and existing Plan Participants as of the Freeze
Date will continue to receive accrued benefits under the Plan. Active
independent trustees as of the Freeze Date have each elected a distribution
method with respect to their benefits under the Plan. During the year ended
January 31, 2007, the Portfolio's projected benefit obligations were increased
by $13,776 and payments of $355 were made to retired trustees, resulting in an
accumulated liability of $13,421 as of January 31, 2007.

      The Board of Trustees has adopted a compensation deferral 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
Portfolio. 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 Portfolio or in other Oppenheimer funds selected by
the Trustee. The Portfolio purchases shares of the funds selected for deferral
by the Trustee in amounts equal to his or her deemed investment, resulting in a
Portfolio 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 Portfolio, and will not materially affect the
Portfolio's assets, liabilities or net investment income per share. Amounts will
be deferred until distributed in accordance to the compensation deferral 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 and 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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Portfolio 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 Portfolio pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Portfolio, 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
Portfolio 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 Portfolio'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 Portfolio. In
the normal course of business, the Portfolio may also enter into contracts that
provide general indemnifications. The Portfolio's maximum exposure under these
arrangements is unknown as this would be dependent on future claims that may be
made against the Portfolio. 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 or the Transfer Agent), a
division of the Manager, acts as the transfer and shareholder servicing agent
for the Portfolio. The Portfolio pays OFS a per account fee. For the year ended
January 31, 2007, the Portfolio paid $388,730 to OFS for services to the
Portfolio.

     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 Portfolio, OppenheimerFunds Distributor, Inc. (the
Distributor) acts as the Portfolio's principal underwriter in the continuous
public offering of the Portfolio's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Portfolio 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 Portfolio. 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
Portfolio under the plan are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The
Portfolio 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
Portfolio 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 Portfolio 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 Portfolio 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
determines its uncompensated expenses under the plan at calendar quarter ends.
The Distributor's aggregate uncompensated expenses under the plan at December
31, 2006 for Class B, Class C and Class N shares were $978,843, $487,187 and
$248,623, respectively. Fees incurred by the Portfolio 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 Portfolio. They are deducted from the
proceeds of sales of Portfolio 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 CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Manager has voluntarily agreed to a
total expense limitation on the aggregate amount of combined direct
(fund-of-funds level) and indirect expense so that "Total expenses" as a
percentage of average daily net assets will not exceed the following annual
rates: 1.45%, 2.20%, 2.20%, 1.70% and 1.20%, for Class A, Class B, Class C,
Class N and Class Y, respectively. The Manager may modify or terminate this
undertaking at any time without notice to shareholders. These expense
limitations do not include Extraordinary Expenses and other expenses not
incurred in the ordinary course of the Portfolio's business. Notwithstanding the
foregoing limits, the Manager is not required to waive or reimburse Portfolio
expenses in excess of indirect management fees earned from investments in
Underlying Funds to assure that expenses do not exceed those limits.

     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. This
undertaking may be amended or withdrawn at any time.

     The Manager will waive fees and/or reimburse Portfolio expenses in an
amount equal to the indirect management fees incurred through the Portfolio's
investment in IMMF. During the year ended January 31, 2007, the Manager waived
$221 for IMMF management fees.

5. RECENT ACCOUNTING PRONOUNCEMENTS

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 Portfolio's tax returns to determine
whether it is "more-likely-than-not" that tax positions taken in the Portfolio'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

5. RECENT ACCOUNTING PRONOUNCEMENTS Continued

not be fully realized. FIN 48 is effective for fiscal years beginning after
December 15, 2006. As of January 31, 2007, the Manager has evaluated the
implications of FIN 48 and does not currently anticipate a material impact to
the Portfolio's financial statements. The Manager will continue to monitor the
Portfolio's tax positions prospectively for potential future impacts.

      In September 2006, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of January 31, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

- --------------------------------------------------------------------------------
6. 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 excluding the Portfolio) 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 PORTFOLIO SERIES:

We have audited the accompanying statement of assets and liabilities of Equity
Investor Fund, formerly Aggressive Investor Fund (one of the portfolios
constituting the Oppenheimer Portfolio Series), including the statement of
investments, as of January 31, 2007, the related statement of operations for the
year then ended, and the statements of changes in net assets and the financial
highlights for the year then ended and for the period April 5, 2005
(commencement of operations) to January 31, 2006. These financial statements and
financial highlights are the responsibility of the Portfolio'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 January 31, 2007, 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
Equity Investor Fund as of January 31, 2007, the results of its operations for
the year then ended, and the changes in its net assets and the financial
highlights for the year then ended and for the period April 5, 2005
(commencement of operations) to January 31, 2006, in conformity with U.S.
generally accepted accounting principles.

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

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Portfolio during
calendar year 2006. Regulations of the U.S. Treasury Department require the
Portfolio to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.0417 per share were paid to Class A,
Class B, Class C, Class N and Class Y shareholders, respectively, on December
29, 2006. 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).

      Dividends, if any, paid by the Portfolio during the fiscal year ended
January 31, 2007 which are not designated as capital gain distributions should
be multiplied by 49.79% to arrive at the amount eligible for the corporate
dividend-received deduction.

      A portion, if any, of the dividends paid by the Portfolio during the
fiscal year ended January 31, 2007 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Portfolio has received qualified dividend income as stipulated by
recent tax legislation. $3,146,085 of the Portfolio's fiscal year taxable income
may be eligible for the lower individual income tax rates. In early 2007,
shareholders of record received information regarding the percentage of
distributions that are eligible for lower individual income tax rates.

      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 January 31, 2007, $23,237 or 0.59% of the ordinary distributions paid
by the Portfolio qualifies as an interest related dividend.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Portfolio 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 PORTFOLIO'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
investment advisory agreement (the "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 Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information about the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel who provide such services. The Manager's duties
include providing the Fund with the services of the portfolio managers and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy

required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.

      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 took account of the fact 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 has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Rudi
Schadt, Jerry Webman and Kurt Wolfgruber, the members of the Fund's Asset
Allocation Team. The Board members also considered their experiences with the
Manager and its officers and other personnel through their service on the boards
of the Fund and other funds advised by the Manager. The Board considered
information regarding the quality of services provided by affiliates of the
Manager, which its members have become knowledgeable about in connection with
the renewal of the Fund's service agreements. In light of the foregoing, the
Board concluded that the Fund benefits from the services provided under the
Agreement and from the Manager's experience, reputation, personnel, operations,
and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
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 all other retail front-end load and
no-load global multi-cap core funds advised by other investment advisers. The
Board noted that the Fund's one-year and since inception performance were below
its peer group median.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to the fees and services for other clients or accounts advised by
the Manager. The independent consultant provided comparative data in regard to
the fees and expenses of the Fund, other multi-cap core funds of funds, one
other international multi-cap core fund of funds and other funds with comparable
asset levels and distribution features. The Board noted that the Manager has
agreed to voluntarily limit the aggregate amount of combined direct
(fund-of-funds level) and indirect expenses so that total annual portfolio and
underlying fund operating expenses as a percentage of average daily net assets
will not exceed the

following annual rates: 1.45% for Class A, 2.20% for Class B, 2.20% for Class C,
1.70% for Class N and 1.20% for Class Y. The Manager may modify or terminate
that undertaking at any time without notice to shareholders. The Board noted
that the Fund does not pay a management fee and that the Fund's total expenses
are lower than its peer group median.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Fund, the extent to which
those economies of scale would benefit the Fund's shareholders and the current
level of Fund assets.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. 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 to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided.

      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 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 are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the 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 Agreement,
including the management fee, in light of all of the surrounding circumstances.

PORTFOLIO PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE PORTFOLIO PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS,
INC., OF THE PORTFOLIO'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JANUARY 31,
2007, FOLLOWED BY A GRAPHICAL COMPARISON OF THE PORTFOLIO'S PERFORMANCE TO AN
APPROPRIATE BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE. For its fiscal year ending
January 31, 2007, the Portfolio underperformed its benchmark, the S&P 500 Index.
We attribute the Portfolio's underperformance to its allocation to fixed-income
funds, which as an asset class underperformed equities over the period.

      In contrast, contributors to the Portfolio's competitive performance
included the strong returns generated by the Portfolio's approximately 20%
tactical (active) allocation component, which benefited from significant
allocations to international funds and sector focused fixed income funds.
Additionally, the Portfolio's static allocation to alternative investments,
specifically its holdings in Oppenheimer Real Estate Fund's Class Y shares,
greatly added to overall results.

      During the period, the Portfolio in general benefited from its large
equity exposure. Equities proved to be volatile over the period hitting lows in
mid-summer and then rapidly advancing through period end. For example, the S&P
500 Index rose 14.53% over the 12-month reporting period, despite returning only
0.67% for the first six months. In addition, the Portfolio's exposure to foreign
markets added to returns. In addition to performance gained through its
allocations to international equities, the Portfolio's tactical component
benefited from its exposure to Oppenheimer Champion Income Fund Class Y Shares
and Oppenheimer International Bond Fund Class Y Shares. We also introduced a
derivative overlay strategy during the period. The purpose of this new strategy
is to help maximize performance results by enabling our portfolio management
team to effectively respond to changing market conditions by implementing
sizable positions quickly and efficiently. Although this new strategy had a
neutral affect on performance over the period, we believe going forward it will
add to results.

      Within the strategic component, the Portfolio's allocation to alternative
investments, primarily its position in Oppenheimer Real Estate Fund Class Y
Shares, contributed to performance. The success of Oppenheimer Real Estate Fund
can be attributed, in part, to its profitable investments in the office,
apartment and industrial sectors.

      Lastly, although fixed income as an asset class underperformed equities
over the period, the underlying bond funds held within the strategic component
added to the Portfolio's returns. Contributors to performance included the
Portfolio's allocations to Oppenheimer Core Bond Fund Class Y Shares and
Oppenheimer Strategic Income Fund Class Y Shares.


                           10 | ACTIVE ALLOCATION FUND



COMPARING THE PORTFOLIO'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 Portfolio held until January 31, 2007. Performance is measured from the
inception of Classes A, B, C, N and Y on April 5, 2005. The Portfolio'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 Portfolio's performance is compared to the performance of the S&P 500
Index. The S&P 500 Index is an unmanaged index of equity securities. 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 Portfolio's performance reflects the effects of the Portfolio's
business and operating expenses. While index comparisons may be useful to
provide a benchmark for the Portfolio's performance, it must be noted that the
Portfolio'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 Portfolio'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 Portfolio or any gains you may realize if you sell your shares.

INVESTORS SHOULD CONSIDER THE PORTFOLIO'S INVESTMENT OBJECTIVES, RISKS, AND
OTHER CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE PORTFOLIO'S
PROSPECTUS CONTAINS THIS AND OTHER INFORMATION ABOUT THE PORTFOLIO, 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.

PORTFOLIO EXPENSES
- --------------------------------------------------------------------------------

PORTFOLIO EXPENSES. As a shareholder of the Portfolio, 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 Portfolio expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Portfolio 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 January 31, 2007.

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 Portfolio'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
Portfolio'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 Portfolio 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 | ACTIVE ALLOCATION FUND



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.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Portfolio'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,
excluding all underlying fund expenses, based on the 6-month period ended
January 31, 2007 are as follows:

CLASS                EXPENSE RATIOS
- ------------------------------------
Class A                  0.51%
- ------------------------------------
Class B                  1.29
- ------------------------------------
Class C                  1.27

Class N                  0.70
- ------------------------------------
Class Y                  0.11

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

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Portfolio Series (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
Active Allocation Fund (the "Portfolio") is a series of the Fund whose
investment objective is to seek long term growth of capital with a secondary
objective of current income. The Portfolio is a special type of mutual fund
known as a "fund of funds" because it invests in other mutual funds. The
Portfolio normally invests in a portfolio consisting of a target weighted
allocation in Class A or Class Y shares of other Oppenheimer funds. The Fund's
investment advisor is OppenheimerFunds, Inc. (the "Manager").

      The Portfolio 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 Portfolio 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.

      Under normal market conditions, the Manager will invest the Portfolio's
assets in shares of Oppenheimer Core Bond Fund, Oppenheimer Capital Appreciation
Fund, Oppenheimer Global Fund, Oppenheimer Global Opportunities Fund,
Oppenheimer Main Street Fund(R), Oppenheimer Main Street Opportunity Fund(R),
Oppenheimer Main Street Small Cap Fund(R), Oppenheimer Real Estate Fund,
Oppenheimer Strategic Income Fund, Oppenheimer Value Fund and Oppenheimer
Institutional Money Market Fund (individually, an "Underlying Fund" and
collectively, the "Underlying Funds").

      In addition, up to 20% of the Portfolio's net assets may be invested
according to a tactical allocation among up to four Oppenheimer funds, which are
also considered Underlying Funds, or money market securities based on
recommendations made by the Manager.

Oppenheimer Funds:
Oppenheimer Capital Appreciation Fund
Oppenheimer Core Bond Fund
Oppenheimer Champion Income Fund
Oppenheimer Developing Markets Fund
Oppenheimer Discovery Fund
Oppenheimer Gold & Special Minerals Fund
Oppenheimer Growth Fund


                           32 | ACTIVE ALLOCATION FUND

Oppenheimer International Small Company Fund
Oppenheimer Limited-Term Government Fund
Oppenheimer MidCap Fund
Oppenheimer Money Market Fund, Inc.
Oppenheimer Quest International Value Fund, Inc.
Oppenheimer Commodity Strategy Total Return Fund(R)
Oppenheimer Small- & Mid- Cap Value Fund
Oppenheimer U.S. Government Trust
Oppenheimer Value Fund

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Portfolio calculates the net asset value of each class
of shares based upon the net asset value of the applicable Underlying Fund 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 trading. For each Underlying
Fund, the net asset value per share for a class of shares on a "regular business
day" is determined by dividing the value of the Underlying Fund's net assets
attributable to that class by the number of shares of that class outstanding on
that day. To determine net asset values, the Underlying Fund assets are valued
primarily on the basis of current market quotations. If market quotations are
not readily available or do not accurately reflect fair value for a security (in
the Manager's judgment) or if a security's value has been materially affected by
events occurring after the close of the exchange or market on which the security
is principally traded, that security may be valued by another method that the
Underlying Fund's Board of Trustees/Directors believes accurately reflects the
fair value. Because some foreign securities trade in markets and on exchanges
that operate on weekends and U.S. holidays, the values of some of the Underlying
Fund's foreign investments may change on days when investors cannot buy or
redeem Underlying Fund shares.

      Short-term "money market type" debt securities with remaining maturities
of sixty days or less are valued at amortized cost (which approximates market
value).

- --------------------------------------------------------------------------------
RISKS OF INVESTING IN THE UNDERLYING FUNDS. Each of the Underlying Funds in
which the Portfolio invests has its own investment risks, and those risks can
affect the value of the Portfolio's investments and therefore the value of the
Portfolio's shares. To the extent that the Portfolio invests more of its assets
in one Underlying Fund than in another, the Portfolio will have greater exposure
to the risks of that Underlying Fund.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Portfolio is
permitted to invest daily available cash balances in an affiliated money market
fund. The Portfolio may invest the available cash in Class E shares of
Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current income
and stability of principal. IMMF is a registered open-end management investment
company, regulated as a

money market fund under the Investment Company Act of 1940, as amended. The
Manager is also the investment advisor of IMMF. The Portfolio's investment in
IMMF is included in the Statement of Investments. As a shareholder, the
Portfolio is subject to its proportional share of IMMF's Class E expenses,
including its management fee. The Manager will waive fees and/or reimburse
Portfolio expenses in an amount equal to the indirect management fees incurred
through the Portfolio's investment in IMMF.

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF BALANCE SHEET RISK. The Portfolio enters into financial
instrument transactions (such as swaps, futures, options and other derivatives)
that may have off-balance sheet market risk. Off-balance sheet market risk
exists when the maximum potential loss on a particular financial instrument is
greater than the value of such financial instrument, as reflected in the
Portfolio's Statement of Assets and Liabilities.

- --------------------------------------------------------------------------------
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 Portfolio 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 Portfolio must satisfy under the income tax regulations, losses
the Portfolio 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 UNREALIZED

1. During the fiscal year ended January 31, 2007, the Portfolio did not utilize
any capital loss carryforward.

2. During the fiscal year ended January 31, 2006, the Portfolio 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


                           34 | ACTIVE ALLOCATION FUND



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
Portfolio. Accordingly, the following amounts have been reclassified for January
31, 2007. Net assets of the Portfolio were unaffected by the reclassifications.

                                                                 REDUCTION TO

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of January 31, 2007 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and

TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
(the "Plan") for the Portfolio's independent trustees. Benefits are based on
years of service and fees paid to each trustee during their period of service.
The Plan was frozen with respect to adding new participants effective December
31, 2006 (the "Freeze Date") and existing Plan Participants as of the Freeze
Date will continue to receive accrued benefits under the Plan. Active
independent trustees as of the Freeze Date have each elected a distribution
method with respect to their benefits under the Plan. During the year ended
January 31, 2007, the Portfolio's projected benefit obligations were increased
by $77,487 and payments

of $1,985 were made to retired trustees,  resulting in an accumulated  liability
of $75,502 as of January 31, 2007.

      The Board of Trustees has adopted a compensation deferral 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
Portfolio. 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 Portfolio or in other Oppenheimer funds selected by
the Trustee. The Portfolio purchases shares of the funds selected for deferral
by the Trustee in amounts equal to his or her deemed investment, resulting in a
Portfolio 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 Portfolio, and will not materially affect the
Portfolio's assets, liabilities or net investment income per share. Amounts will
be deferred until distributed in accordance to the compensation deferral 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 and 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 Portfolio 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 Portfolio pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Portfolio, 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
Portfolio 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.


                           36 | ACTIVE ALLOCATION FUND



- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Portfolio'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 Portfolio. In
the normal course of business, the Portfolio may also enter into contracts that
provide general indemnifications. The Portfolio's maximum exposure under these
arrangements is unknown as this would be dependent on future claims that may be
made against the Portfolio. 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

MANAGEMENT FEES. Under the investment advisory agreement, the Manager does not
charge a management fee, but rather collects indirect management fees from
investments in the Underlying Funds. The weighted indirect management fees
collected from the Underlying Funds, as a percent of average daily net assets of
the Portfolio for the year ended January 31, 2007 was 0.58%.

      The Portfolio pays the Manager an asset allocation fee equal to an annual
rate of 0.10% of the average daily net assets of the Portfolio.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS or the Transfer Agent), a
division of the Manager, acts as the transfer and shareholder servicing agent
for the Portfolio. The Portfolio pays OFS a per account fee. For the year ended
January 31, 2007, the Portfolio paid $1,380,526 to OFS for services to the
Portfolio.

      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.

- --------------------------------------------------------------------------------
OFFERING AND ORGANIZATIONAL COSTS. The Manager paid all offering and
organizational costs associated with the registration and seeding of the
Portfolio.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Portfolio, OppenheimerFunds Distributor, Inc. (the
Distributor) acts as the


                           38 | ACTIVE ALLOCATION FUND



Portfolio's principal underwriter in the continuous public offering of the
Portfolio's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Portfolio 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 Portfolio. 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
Portfolio under the plan are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The
Portfolio 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
Portfolio 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 Portfolio 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 Portfolio 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
determines its uncompensated expenses under the plan at calendar quarter ends.
The Distributor's aggregate uncompensated expenses under the plan at December
31, 2006 for Class B, Class C and Class N shares were $5,145,968, $2,910,863 and
$897,937, respectively. Fees incurred by the Portfolio 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 Portfolio. They are deducted from the
proceeds of sales of Portfolio 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 CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

level) and indirect expense so that "Total expenses" as a percentage of average
daily net assets will not exceed the following annual rates: 1.45%, 2.20%,
2.20%, 1.70% and 1.20%, for Class A, Class B, Class C, Class N and Class Y,
respectively. During the year ended January 31, 2007, the Manager reimbursed the
Portfolio $20,446, $7,730, $9,156, $2,146 and $44, for the Class A, Class B,
Class C, Class N and Class Y shares, respectively. The Manager may modify or
terminate this undertaking at any time without notice to shareholders. These
expense limitations do not include Extraordinary Expenses and other expenses not
incurred in the ordinary course of the Portfolio's business. Notwithstanding the
foregoing limits, the Manager is not required to waive or reimburse Portfolio
expenses in excess of indirect management fees earned from investments in
Underlying Funds to assure that expenses do not exceed those limits.

      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. This
undertaking may be amended or withdrawn at any time.

      The Manager will waive fees and/or reimburse Portfolio expenses in an
amount equal to the indirect management fees incurred through the Portfolio's
investment in IMMF. During the year ended January 31, 2007, the Manager waived
$1,254 for IMMF management fees.

- --------------------------------------------------------------------------------
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 Portfolio 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 Portfolio may also buy or write put or call options on these
futures contracts.

      The Portfolio generally sells futures contracts as a hedge against
increases in interest rates and decreases in market value of portfolio
securities. The Portfolio 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 Portfolio 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 Portfolio 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 Portfolio 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


                           40 | ACTIVE ALLOCATION FUND



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 January 31, 2007, the Portfolio had outstanding futures contracts as
follows:

6. TOTAL RETURN SWAP CONTRACTS

A total return swap is an agreement under which a set of future cash flows is
exchanged between two counterparties. One cash flow stream will typically be
based on a reference interest rate or index and the other on the total return of
a reference asset such as a security, a basket of securities, or an index. The
total return includes appreciation or depreciation on the reference asset, plus
any interest or dividend payments. Payments under the swap are based on an
agreed upon principal amount but since this principal amount is not exchanged,
it represents neither an asset nor a liability to either counter-party, and is
referred to as notional. Total return swaps are marked to market daily using
different sources, including quotations from counterparties, pricing services,
brokers or market makers. The unrealized appreciation (depreciation) related to
the change in the valuation of the notional amount of the swap is combined with
the amount due to (owed by) the Portfolio at termination or settlement and
disclosed separately on the Statement of Assets and Liabilities. The net change
in this amount is included on the Statement of Operations. The Portfolio also
records any periodic payments received from (paid to) the counterparty,
including at termination, under such contracts as realized gain (loss) on the
Statement of Operations. The primary risks associated with total return swaps
are credit risks (if the counterparty fails to meet its obligations) and market
risk (if there is no liquid market for the agreement or unfavorable changes
occur in the reference asset).

7. RECENT ACCOUNTING PRONOUNCEMENTS

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


                           42 | ACTIVE ALLOCATION FUND



evaluation of tax positions taken in the course of preparing the Portfolio's tax
returns to determine whether it is "more-likely-than-not" that tax positions
taken in the Portfolio'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 January 31, 2007, the
Manager has evaluated the implications of FIN 48 and does not currently
anticipate a material impact to the Portfolio's financial statements. The
Manager will continue to monitor the Portfolio's tax positions prospectively for
potential future impacts.

      In September 2006, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of January 31, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

- --------------------------------------------------------------------------------
8. 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 excluding the Portfolio) 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 PORTFOLIO SERIES:

We have audited the accompanying statement of assets and liabilities of Active
Allocation Fund (one of the portfolios constituting the Oppenheimer Portfolio
Series), including the statement of investments, as of January 31, 2007, the
related statement of operations for the year then ended, and the statements of
changes in net assets and the financial highlights for the year then ended and
for the period April 5, 2005 (commencement of operations) to January 31, 2006.
These financial statements and financial highlights are the responsibility of
the Portfolio'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 January 31, 2007, 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
Active Allocation Fund as of January 31, 2007, the results of its operations for
the year then ended, and the changes in its net assets and the financial
highlights for the year then ended and for the period April 5, 2005
(commencement of operations) to January 31, 2006, in conformity with U.S.
generally accepted accounting principles.

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

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Portfolio during
calendar year 2006. Regulations of the U.S. Treasury Department require the
Portfolio to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.0424 per share were paid to Class A,
Class B, Class C, Class N and Class Y shareholders, respectively, on December
29, 2006. 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).

      Dividends, if any, paid by the Portfolio during the fiscal year ended
January 31, 2007 which are not designated as capital gain distributions should
be multiplied by 22.38% to arrive at the amount eligible for the corporate
dividend-received deduction.

      A portion, if any, of the dividends paid by the Portfolio during the
fiscal year ended January 31, 2007 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Portfolio has received qualified dividend income as stipulated by
recent tax legislation. $12,114,010 of the Portfolio's fiscal year taxable
income may be eligible for the lower individual income tax rates. In early 2007,
shareholders of record received information regarding the percentage of
distributions that are eligible for lower individual income tax rates.

      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 January 31, 2007, $152,830 or 0.51% of the ordinary distributions
paid by the Portfolio qualifies as an interest related dividend and $571,891 or
100% of the short-term capital gain distribution paid by the Portfolio qualifies
as a short-term capital gain dividend.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Portfolio 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 PORTFOLIO'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
investment advisory agreement (the "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 Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information about the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel who provide such services. The Manager's duties
include providing the Fund with the services of the portfolio managers and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.

BOARD APPROVAL OF THE PORTFOLIO'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued
- --------------------------------------------------------------------------------

      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 took account of the fact 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 has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Rudi
Schadt, Jerry Webman, Kurt Wolfgruber and Caleb Wong, the members of the Fund's
Asset Allocation Team. The Board members also considered their experiences with
the Manager and its officers and other personnel through their service on the
boards of the Fund and other funds advised by the Manager. The Board considered
information regarding the quality of services provided by affiliates of the
Manager, which its members have become knowledgeable about in connection with
the renewal of the Fund's service agreements. In light of the foregoing, the
Board concluded that the Fund benefits from the services provided under the
Agreement and from the Manager's experience, reputation, personnel, operations,
and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
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 all other retail front-end load and
no-load moderate mixed-asset target allocation funds advised by other investment
advisers. The Board noted that the Fund's one-year and since inception
performance were better than its peer group median.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to the fees and services for other clients or accounts advised by
the Manager. The independent consultant provided comparative data in regard to
the fees and expenses of the Fund, one other mixed-asset target allocation
moderate fund of funds, other flexible portfolio funds of funds and other funds
with comparable asset levels and distribution features. The Board noted that the
Manager has agreed to voluntarily limit the aggregate amount of combined direct
(fund-of-funds level) and indirect expenses so that total annual portfolio and
underlying fund operating expenses as a percentage of average daily net assets
will


                           48 | ACTIVE ALLOCATION FUND



not exceed the following annual rates: 1.45% for Class A, 2.20% for Class B,
2.20% for Class C, 1.70% for Class N and 1.20% for Class Y. The Manager may
modify or terminate that undertaking at any time without notice to shareholders.
The Board noted that the Fund's contractual and actual management fees and total
expenses are lower than its peer group median.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Fund, the extent to which
those economies of scale would benefit the Fund's shareholders and the current
level of Fund assets.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. 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 to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided.

      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 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 are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the 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 Agreement,
including the management fee, in light of all of the surrounding circumstances.

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.

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 January 31, 2007, 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.
