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

Total returns include changes in share price and reinvestment of dividends and
capital gains distributions in a hypothetical investment for the periods shown.
Cumulative total returns are not annualized. 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 July 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the 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.


                  12 | CONSERVATIVE INVESTOR FUND


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 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.

Expenses are equal to the Portfolio's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 181/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding all underlying fund expenses, based on the 6-month period ended July
31, 2006 are as follows:

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
High Yield Fund, Oppenheimer International Bond Fund, Oppenheimer Limited-Term
Government Fund, Oppenheimer Main Street Fund(R), Oppenheimer Real Asset
Fund(R), Oppenheimer Real Estate Fund and Oppenheimer Value 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 Funds' 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

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

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.

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

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

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

      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.


                  26 | CONSERVATIVE INVESTOR FUND


      As of July 31, 2006, the Portfolio had available for federal income tax
purposes an estimated capital loss carryforward of $52,056 expiring by 2015.
This estimated capital loss carryforward represents carryforward as of the end
of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. During the
period ended January 31, 2006, the Portfolio did not have any capital loss
carryforward.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
for the Portfolio's independent trustees. Benefits are based on years of service
and fees paid to each trustee during the years of service. During the six months
ended July 31, 2006, the Portfolio's projected benefit obligations were
increased by $3,605 and no payments were made to retired trustees, resulting in
an accumulated liability of $3,605 as of July 31, 2006.

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

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

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

      The Fund has authorized an unlimited number of $0.001 par value shares of
beneficial interest of each class. Transactions in shares of beneficial interest

             Investment securities       $63,236,634     $3,749,926

- --------------------------------------------------------------------------------
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 six months ended July 31, 2006 was 0.55%.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), 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 six months ended July 31, 2006,
the Portfolio paid $45,209 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

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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's
aggregate uncompensated expenses under the plan at July 31, 2006 for Class B,
Class C and Class N shares were $244,521, $266,820 and $162,085, 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 Combined Total Annual and
Underlying Fund Operating 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 paid directly by the Portfolio to 0.35% of average annual net assets
for each class. This undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the 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 July 31, 2006, the Manager is evaluating the implications of FIN
48. Its impact in the Portfolio's financial statements has not yet been
determined.

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

NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
6. LITIGATION Continued

      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.

                  10 | MODERATE INVESTOR FUND


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 July 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the 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.

PORTFOLIO EXPENSES  Continued
- --------------------------------------------------------------------------------

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 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.

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
High Yield Fund, Oppenheimer International Bond Fund, Oppenheimer Limited-Term
Government Fund, Oppenheimer Main Street Fund(R), Oppenheimer Main Street
Opportunity Fund(R), Oppenheimer Real Asset Fund(R), Oppenheimer Real Estate
Fund and Oppenheimer Value 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 Funds' 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


                  24 | MODERATE INVESTOR FUND


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.

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

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

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

      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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

      As of July 31, 2006, the Portfolio had available for federal income tax
purposes an estimated capital loss carryforward of $170,881 expiring by 2015.
This estimated capital loss carryforward represents carryforward as of the end
of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. During the
period ended January 31, 2006, the Portfolio did not have any capital loss
carryforward.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
for the Portfolio's independent trustees. Benefits are based on years of service
and fees paid to each trustee during the years of service. During the six months
ended July 31, 2006, the Portfolio's projected benefit obligations were
increased by $9,142 and no payments were made to retired trustees, resulting in
an accumulated liability of $9,142 as of July 31, 2006.

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


                  26 | MODERATE INVESTOR FUND


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.

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

3. PURCHASES AND SALES OF SECURITIES

The aggregate cost of purchases and proceeds from sales of securities, other
than short-term obligations, for the six months ended July 31, 2006, were as
follows:

                                             PURCHASES         SALES
           ---------------------------------------------------------
           Investment securities          $194,688,872    $8,541,098

- --------------------------------------------------------------------------------
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 six months ended July 31, 2006 was 0.56%.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), 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 six months ended July 31, 2006,
the Portfolio paid $158,319 to OFS for services to the Portfolio.


                  28 | 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.

- --------------------------------------------------------------------------------
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's
aggregate uncompensated expenses under the plan at July 31, 2006 for Class B,
Class C and Class N shares were $1,162,326, $766,342 and $234,481, 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 Combined Total Annual and
Underlying Fund Operating 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.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the 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 July 31, 2006, the Manager is evaluating the implications of FIN
48. Its impact in the Portfolio's financial statements has not yet been
determined.


                  30 | MODERATE INVESTOR FUND


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

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 July 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the 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


                  12 | 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 181/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding all underlying fund expenses, based on the 6-month period ended July
31, 2006 are as follows:

CLASS          EXPENSE RATIOS
- -----------------------------
Class A             0.50%
- -----------------------------
Class B             1.29
- -----------------------------
Class C             1.27
- -----------------------------
Class N             0.70
- -----------------------------
Class Y             0.13

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 and Oppenheimer Value Fund (individually, an
"Underlying Fund" and collectively, the "Underlying Funds").

          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 Funds' 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


                  26 | ACTIVE ALLOCATION FUND


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.

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

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

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

      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.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
for the Portfolio's independent trustees. Benefits are based on years of service
and fees paid to each trustee during the years of service. During the six months
ended July 31, 2006, the Portfolio's projected benefit obligations were
increased by $25,180 and no payments were made to retired trustees, resulting in
an accumulated liability of $25,180 as of July 31, 2006.

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

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

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


                  28 | ACTIVE ALLOCATION FUND


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.

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

      Investment securities                $830,408,522      $246,884,029

- --------------------------------------------------------------------------------
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 six months ended July 31, 2006 was 0.59%.

      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), 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 six months ended July 31, 2006,
the Portfolio paid $505,771 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 pro-


                  30 | ACTIVE ALLOCATION FUND


vided 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's
aggregate uncompensated expenses under the plan at July 31, 2006 for Class B,
Class C and Class N shares were $4,128,785, $2,352,281 and $616,945,
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 Combined Total Annual and
Underlying Fund Operating 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 six months ended July 31, 2006, the Manager

reimbursed the Portfolio $6,099, $2,381, $2,680, $583 and $8, 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.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the 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 July 31, 2006, the Manager is evaluating the implications of FIN
48. Its impact in the Portfolio's financial statements has not yet been
determined.

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


                  32 | ACTIVE ALLOCATION FUND


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.

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 July 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the 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


                  11 | AGGRESSIVE 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.

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 181/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding all underlying fund expenses, based on the 6-month period ended July
31, 2006 are as follows:

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.
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) and Oppenheimer
Value 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 Funds' 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


                  24 | AGGRESSIVE INVESTOR FUND


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.

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

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

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

      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.

      As of July 31, 2006, the Portfolio had available for federal income tax
purposes an estimated capital loss carryforward of $8,349 expiring by 2014. This
estimated capital loss carryforward represents carryforward as of the end of the
last fiscal year, increased for


                  25 | AGGRESSIVE INVESTOR FUND


NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------

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

losses deferred under tax accounting rules to the current fiscal year and is
increased or decreased by capital losses or gains realized in the first six
months of the current fiscal year. During the year ended January 31, 2006, the
Portfolio did not utilize any capital loss carryforward.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Portfolio has adopted an unfunded retirement plan
for the Portfolio's independent trustees. Benefits are based on years of service
and fees paid to each trustee during the years of service. During the six months
ended July 31, 2006, the Portfolio's projected benefit obligations were
increased by $4,301 and no payments were made to retired trustees, resulting in
an accumulated liability of $4,301 as of July 31, 2006.

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


                  26 | AGGRESSIVE INVESTOR FUND


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.

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

The Portfolio has authorized an unlimited number of $0.001 par value shares of
beneficial interest of each class. Transactions in shares of beneficial interest

- --------------------------------------------------------------------------------
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 six months ended July 31, 2006 was 0.58%.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), 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 six months ended July 31, 2006,
the Portfolio paid $139,257 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.


                  28 | AGGRESSIVE INVESTOR FUND


- --------------------------------------------------------------------------------
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's
aggregate uncompensated expenses under the plan at July 31, 2006 for Class B,
Class C and Class N shares were $756,186, $417,895 and $137,321, 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.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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 Combined Total Annual and
Underlying Fund Operating 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.

- --------------------------------------------------------------------------------
5. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the 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 July 31, 2006, the Manager is evaluating the implications of FIN
48. Its impact in the Portfolio's financial statements has not yet been
determined.

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


                  30 | AGGRESSIVE INVESTOR FUND


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 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 07/31/2006, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

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

ITEM 12. EXHIBITS.

(a)   (1)   Not applicable to semiannual reports.

      (2)   Exhibits attached hereto.

      (3)   Not applicable.

(b)   Exhibit attached hereto.
