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 Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares.

THIS SEMIANNUAL REPORT MUST BE PRECEDED OR ACCOMPANIED BY THE CURRENT PROSPECTUS
OF OPPENHEIMER CALIFORNIA MUNICIPAL FUND. BEFORE INVESTING IN ANY OF THE
OPPENHEIMER FUNDS, INVESTORS SHOULD CAREFULLY CONSIDER A FUND'S INVESTMENT
OBJECTIVES, RISKS, CHARGES AND EXPENSES. FUND PROSPECTUSES CONTAIN THIS AND
OTHER INFORMATION ABOUT THE FUNDS. FOR MORE INFORMATION, ASK YOUR FINANCIAL
ADVISOR, CALL US AT 1.800.525.7048, OR VISIT OUR WEBSITE AT
WWW.OPPENHEIMERFUNDS.COM. READ PROSPECTUSES CAREFULLY BEFORE INVESTING.

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

CLASS A shares of the Fund were first publicly offered on 11/3/88. The average
annual total returns are shown net of the applicable 4.75% maximum initial sales
charge.

CLASS B shares of the Fund were first publicly offered on 5/3/93. The average
annual total returns are shown net of the applicable contingent deferred sales
charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to Class A
shares 72 months after purchase, the 10-year return for Class B uses Class A
performance for the period after conversion. Class B shares are subject to an
annual 0.75% asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 11/1/95. The average
annual total returns are shown net of the applicable 1% contingent deferred
sales charge for the one-year period. Class C shares are subject to an annual
0.75% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

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

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees (if
applicable); and (2) ongoing costs, including management fees; distribution and
service fees; and other Fund expenses. These examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended January 31, 2008.

ACTUAL EXPENSES. The first section of the table provides information about
actual account values and actual expenses. You may use the information in this
section 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 first section
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 second section of the table
provides information about hypothetical account values and hypothetical expenses
based on the Fund's actual expense ratio for each class of shares, and an
assumed rate of return of 5% per year for each class before expenses, which is
not the actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in


                   17 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



FUND EXPENSES  Continued

the Statement of Additional Information). Therefore, the "hypothetical" section
of the table is 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 FUND'S ANNUALIZED EXPENSE RATIO FOR THAT CLASS,
MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 184/365
(TO REFLECT THE ONE-HALF YEAR PERIOD). THOSE ANNUALIZED EXPENSE RATIOS BASED ON
THE 6-MONTH PERIOD ENDED JANUARY 31, 2008 ARE AS FOLLOWS:

- ----------------------------
Class A            1.63%

Class B            2.45
- ----------------------------
Class C            2.41

THE EXPENSE RATIOS REFLECT REDUCTION TO CUSTODIAN EXPENSES. THE "FINANCIAL
HIGHLIGHTS" TABLES IN THE FUND'S FINANCIAL STATEMENTS, INCLUDED IN THIS REPORT,
ALSO SHOW THE GROSS EXPENSE RATIOS, WITHOUT SUCH WAIVERS OR REIMBURSEMENTS AND
REDUCTION TO CUSTODIAN EXPENSES, IF APPLICABLE.

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

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

Oppenheimer California Municipal Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, open-end
management investment company. The Fund's investment objective is to seek as
high a level of current interest income exempt from federal and California
income taxes for individual investors as is consistent with preservation of
capital. The Fund's investment adviser is OppenheimerFunds, Inc. (the
"Manager").

      The Fund offers Class A, Class B and Class C shares. Class A shares are
sold at their offering price, which is normally net asset value plus a front-end
sales charge. Class B and Class C shares are sold without a front-end sales
charge but may be subject to a contingent deferred sales charge ("CDSC"). All
classes of shares have identical rights and voting privileges with respect to
the Fund in general and exclusive voting rights on matters that affect that
class alone. Earnings, net assets and net asset value per share may differ due
to each class having its own expenses, such as transfer and shareholder
servicing agent fees and shareholder communications, directly attributable to
that class. Class A, B and C have separate distribution and/or service plans.
Class B shares will automatically convert to Class A shares 72 months after the
date of purchase.

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

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of the New York Stock Exchange (the "Exchange"), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for trading. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities traded on a registered U.S.
securities exchange are valued based on the last sale price of the security
traded on that exchange prior to the time when the Fund's assets are valued.
Securities whose principal exchange is NASDAQ(R) are valued based on the closing
price reported by NASDAQ prior to the time when the Fund's assets are valued. In
the absence of a sale, the security is valued at the last sale price on the
prior trading day, if it is within the spread of the closing "bid" and "asked"
prices, and if not, at the closing bid price. Securities traded on foreign
exchanges are valued based on the last sale price on the principal exchange on
which the security is traded, as identified by the portfolio pricing service,
prior to the time when the Fund's assets are valued. In the absence of a sale,
the security is valued at the official closing price on the principal exchange.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of sixty days and all mortgage-backed securities, collateralized
mortgage obligations and other asset-backed securities will be valued at the
mean between the "bid" and "asked" prices. Securities for which market
quotations are not readily available are valued at their fair value. Securities
whose values have been materially affected by what the Manager identifies as a
significant event occurring before the Fund's assets are valued but after the
close of their respective exchanges will be fair valued. Fair value is
determined in good


                   54 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



faith using consistently applied procedures under the supervision of the Board
of Trustees. Shares of a registered investment company that are not traded on an
exchange are valued at the acquired investment company's net asset value per
share. "Money market-type" debt instruments with remaining maturities of sixty
days or less are valued at cost adjusted by the amortization of discount or
premium to maturity (amortized cost), which approximates market value.

- --------------------------------------------------------------------------------
INVERSE FLOATING RATE SECURITIES. The Fund invests in inverse floating rate
securities that pay interest at a rate that varies inversely with short-term
interest rates. Certain of these securities may be leveraged, whereby the
interest rate varies inversely at a multiple of the change in short-term rates.
As interest rates rise, inverse floaters produce less current income. The price
of such securities is more volatile than comparable fixed rate securities. The
Fund may invest up to 20% of its total assets (which includes the effects of
leverage) in inverse floaters. Inverse floaters, including the effects of
leverage, amount to $393,352,116 as of January 31, 2008, which represents 14.56%
of the Fund's total assets.

      Certain inverse floating rate securities are created when the Fund
purchases and subsequently transfers a municipal bond security (the "municipal
bond") to a broker dealer. The municipal bond is typically a fixed rate
security. The broker dealer (the "sponsor") creates a trust (the "Trust") and
deposits the municipal bond. The Trust issues short-term floating rate notes
available to third parties and a residual interest in the municipal bond
(referred to as an "inverse floating rate security") to the Fund. The terms of
these inverse floating rate securities grant the Fund the right to require that
the Trust issuing the inverse floating rate security compel a tender of the
short-term floating rate notes to facilitate the Fund's repurchase of the
underlying municipal bond. Following such a request, the Fund pays the sponsor
the principal amount due to the holders of the short-term floating rate notes
issued by the Trust and exchanges the inverse floating rate security for the
underlying municipal bond. These transactions are considered secured borrowings
for financial reporting purposes. As a result of such accounting treatments, the
Fund includes the municipal bond position on its Statement of Investments (but
does not separately include the inverse floating rate securities received). The
Fund also includes the value of the municipal bond and a payable amount equal to
the short-term floating rate notes issued by the Trust on its Statement of
Assets and Liabilities. The interest rates on these short-term floating rate
notes reset periodically, usually weekly. The holders of these short-term
floating rate notes have the option to tender their investment, to the sponsor
or the Trust's liquidity provider, for redemption at par at each reset date.
Income from the municipal bond position and the interest expense on the payable
for the short-term floating rate notes issued by the Trust are recorded on the
Fund's Statement of Operations. At January 31, 2008, municipal bond holdings
with a value of $507,275,899 shown on the Fund's Statement of Investments are
held by such Trusts and serve as collateral for the $446,940,000 in short-term
floating rate notes issued and outstanding at that date.

1. For a list  of  abbreviations  used in the  Inverse  Floater  table  see the
Portfolio Abbreviations table on page 45 of the Statement of Investments.

2. Represents the current interest rate for a variable rate bond.

3. Security is subject to a shortfall and forbearance agreement.

4. This inverse  floater  settles at a future  date,  at which time the interest
rate will be determined.

The Fund enters into shortfall and forbearance agreements with the sponsors of
certain inverse floaters held by the Fund. These agreements commit the Fund to
reimburse the sponsor of the inverse floater, in certain circumstances, for the
amount of the difference between the liquidation value of the underlying
security (which is the basis of the inverse floater) and the principal amount
due to the holders of the short-term floating rate notes issued by the Trust in
conjunction with the inverse floating rate security. Under the


                   56 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



standard terms of an inverse floating rate security, absent such a shortfall and
forbearance agreement, the Fund would not be required to make such a
reimbursement. The Manager monitors the Fund's potential exposure with respect
to these agreements on a daily basis and intends to take action to terminate the
Fund's investment in such inverse floating rate securities, if it deems it
appropriate to do so. As of January 31, 2008, in addition to the exposure
detailed in the preceding table, the Fund's maximum exposure under such
agreements is estimated at approximately $202,800,000.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. The Fund may purchase
securities on a "when-issued" basis, and may purchase or sell securities on a
"delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis
normally takes place within six months and possibly as long as two years or more
after the trade date. During this period, such securities do not earn interest,
are subject to market fluctuation and may increase or decrease in value prior to
their delivery. The purchase of securities on a when-issued basis may increase
the volatility of the Fund's net asset value to the extent the Fund executes
such transactions while remaining substantially fully invested. When the Fund
engages in when-issued or delayed delivery transactions, it relies on the buyer
or seller, as the case may be, to complete the transaction. Their failure to do
so may cause the Fund to lose the opportunity to obtain or dispose of the
security at a price and yield it considers advantageous. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase.

As of January 31, 2008, the Fund had purchased securities issued on a
when-issued or delayed delivery basis and sold securities issued on a delayed
delivery basis:

                                        WHEN-ISSUED OR DELAYED DELIVERY
                                                     BASIS TRANSACTIONS
               --------------------------------------------------------
               Purchased securities                        $139,691,366
               Sold securities                               85,219,922

- --------------------------------------------------------------------------------
CREDIT RISK. The Fund invests in high-yield, non-investment-grade bonds, which
may be subject to a greater degree of credit risk. Credit risk relates to the
ability of the issuer to meet interest or principal payments or both as they
become due. The Fund may acquire securities in default, and is not obligated to
dispose of securities whose issuers subsequently default. As of January 31,
2008, securities with an aggregate market value of $4,505,735, representing
0.22% of the Fund's net assets, were in default.

- --------------------------------------------------------------------------------
CONCENTRATION RISK. There are certain risks arising from geographic
concentration in any state. Certain economic, regulatory or political
developments occurring in the state may impair the ability of certain issuers of
municipal securities to pay principal and interest on their obligations.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders. Therefore, no federal income or excise tax provision is
required. The Fund files income tax returns in U.S. federal and applicable state
jurisdictions. The statute of limitations on the Fund's tax return filings
generally remain open for the three preceding fiscal reporting period ends.

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

      As of January 31, 2008, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $46,680,498 expiring by 2016.
This estimated capital loss carryforward represents carryforward as of the end
of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. During the
six months ended January 31, 2008, it is estimated that the Fund will not
utilize any of capital loss carryforward to offset realized capital gains.
During the fiscal year ended July 31, 2007, the Fund did not utilize any capital
loss carryforward to offset capital gains realized in that fiscal year.

As of July 31, 2007, the Fund had available for federal income tax purposes
post-October losses of $4,645,961 and unused capital loss carryforwards as
follows:

TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan (the
"Plan") for the Fund's independent trustees. Benefits are based on years of
service and fees paid to each trustee during their period of service. The Plan
was frozen with respect to adding new participants effective December 31, 2006
(the "Freeze Date") and existing Plan Participants as of the Freeze Date will
continue to receive accrued benefits under the Plan. Active independent trustees
as of the Freeze Date have each elected a distribution


                   58 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



method with respect to their benefits under the Plan. During the six months
ended January 31, 2008, the Fund's projected benefit obligations, payments to
retired trustees and accumulated liability were as follows:

           Projected Benefit Obligations Increased              $     841
           Payments Made to Retired Trustees                    $  16,038
           Accumulated Liability as of January 31, 2008         $ 127,584

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

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

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Interest income is recognized on an accrual basis. Discount
and premium, which are included in interest income on the Statement of
Operations, are amortized or accreted daily.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Fund, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Fund
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 increases and
decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

rate as shown in the following table:

              FEE SCHEDULE
              ---------------------------------
              Up to $200 million          0.60%

              Over $1 billion             0.35

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services ("OFS"), a division of the
Manager, acts as the transfer and shareholder servicing agent for the Fund. The
Fund pays OFS a per account fee. For the six months ended January 31, 2008, the
Fund paid $382,391 to OFS for services to the Fund.

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

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan (the
"Plan") for Class A shares under Rule 12b-1 of the Investment Company Act of
1940. Under the Plan, the Fund reimburses the Distributor for a portion of its
costs incurred for services provided to accounts that hold Class A shares.
Reimbursement is made periodically at an annual rate of up to 0.25% of the
average annual net assets of Class A shares of the Fund. The Distributor
currently uses all of those fees to pay dealers, brokers, banks and other
financial institutions periodically for providing personal service and
maintenance of accounts of their customers that hold Class A shares. Any
unreimbursed expenses the Distributor incurs with respect to Class A shares in
any fiscal year cannot be recovered in subsequent periods. Fees incurred by the
Fund under the Plan are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B AND CLASS C SHARES. The Fund has
adopted Distribution and Service Plans (the "Plans") for Class B and Class C
shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the
Distributor for its services in connection with the distribution of those shares
and servicing accounts. Under the Plans, the Fund pays the Distributor an annual
asset-based sales charge of 0.75% on

Class B and Class C shares. The Distributor also receives a service fee of 0.25%
per year under each plan. If either the Class B or Class C plan is terminated by
the Fund or by the shareholders of a class, the Board of Trustees and its
independent trustees must determine whether the Distributor shall be entitled to
payment from the Fund of all or a portion of the service fee and/or asset-based
sales charge in respect to shares sold prior to the effective date of such
termination. The Distributor's aggregate uncompensated expenses under the Plans
at December 31, 2007 for Class B and Class C shares were $2,754,583 and
$6,071,461, respectively. Fees incurred by the Fund under the Plans are detailed
in the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
("CDSC") do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the 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 undertaken
to limit its management fees not to exceed 0.55% of average annual net assets
for each class of shares. This voluntary undertaking may be amended or withdrawn
by the Manager at any time without notice to shareholders.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class. This
undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
5. ILLIQUID SECURITIES

As of January 31, 2008, investments in securities included issues that are
illiquid. Investments may be illiquid because they do not have an active trading
market, making it difficult to value them or dispose of them promptly at an
acceptable price. The Fund will not invest more than 15% of its net assets
(determined at the time of purchase and reviewed periodically) in illiquid
securities. Securities that are illiquid are marked with an applicable footnote
on the Statement of Investments.


                   62 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



- --------------------------------------------------------------------------------
6. BORROWINGS

The Fund can borrow money from banks in amounts up to one third of its total
assets (including the amount borrowed) less all liabilities and indebtedness
other than borrowings to purchase portfolio securities, to meet redemption
obligations or for temporary and emergency purposes. The purchase of securities
with borrowed funds creates leverage in the Fund. The use of leverage will
subject the Fund to greater costs than funds that do not borrow for leverage,
and may also make the Fund's share price more sensitive to interest changes. The
interest on borrowed money is an expense that might reduce the Fund's yield.
Expenses incurred by the Fund with respect to interest on borrowings and
commitment fees are disclosed separately or as other expenses on the Statement
of Operations.

      The Fund entered into a Revolving Credit and Security Agreement (the
"Agreement") with a conduit lender and a bank which enables it to participate
with certain other Oppenheimer funds in a committed, secured borrowing facility
that permits borrowings of up to $1,250,000,000, collectively. To secure the
loan, the Fund pledges investment securities in accordance with the terms of the
Agreement. Interest is charged to the Fund, based on its borrowings, at current
commercial paper issuance rates (4.6038% as of January 31, 2008). The Fund pays
additional fees annually to its lender on its outstanding borrowings to manage
and administer the facility and is allocated its pro-rata share of an annual
commitment fee on the amount of the unused portion of total facility size. The
Fund has the right to prepay such loans and terminate its participation in the
conduit loan facility at any time upon prior notice.

As of January 31, 2008, the Fund had borrowings outstanding at an interest rate
of 4.6038%. Details of the borrowings for the six months ended January 31, 2008
are listed in the following table.

               Average Daily Loan Balance         $  53,459,783
               Average Daily Interest Rate                5.274%
               Fees Paid                          $     115,279
               Interest Paid                      $   1,477,153

- --------------------------------------------------------------------------------
7. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE
MEASUREMENTS. This standard establishes a single authoritative definition of
fair value, sets out a framework for measuring fair value and expands
disclosures about fair value measurements. SFAS No. 157 applies to fair value
measurements already required or permitted by existing standards. SFAS No. 157
is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. As of January
31, 2008, the Manager does not believe the adoption of SFAS No. 157 will
materially impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements on changes in net assets for the
period.

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

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

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

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


                   64 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board took account of the fact that the Manager has had over forty
years of experience as an investment adviser and that its assets under
management rank it among the top mutual fund managers in the United States. The
Board evaluated the Manager's administrative, accounting, legal and compliance
services, and information the Board has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Ronald H.
Fielding, Daniel G. Loughran, Scott S. Cottier, Troy E. Willis, Mark R. DeMitry,
and Marcus V. Franz, the portfolio managers for the Fund, and the Manager's
Rochester Municipal Bond investment team and analysts. The Board members also
considered their experiences with the Manager and its officers and other
personnel through their service on the Boards of the Fund and other funds
advised by the Manager. The Board considered information regarding the quality
of services provided by affiliates of the Manager, which its members have become
knowledgeable about in connection with the renewal of the Fund's service
agreements. In light of the foregoing, the Board concluded that the Fund
benefits from the services provided under the Agreement and from the Manager's
experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each regular quarterly Board meeting, including comparative
performance information. The Board also reviewed information, prepared by the
Manager and by the independent consultant, comparing the Fund's historical
performance to relevant market indices and to the performance of other retail
front-end load and no-load California municipal debt funds advised by other
investment advisers. The Board noted that the Fund's one-year, three-year,
five-year and ten-year performance were better than its peer group median at the
time of its annual review.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also considered the comparability of the fees charged and the services provided
to the Fund to the fees and services for other clients or accounts advised by
the Manager. The independent consultant provided comparative data in regard to
the fees and expenses of the Fund, other California municipal debt funds and
other funds with comparable asset levels and distribution features. The manager
has voluntarily agreed to waive a portion of its management fee so that
management fees will not exceed 0.55% of average annual net assets. This


                   65 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



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

voluntary undertaking may be amended or withdrawn by the Manager at any time
without shareholder notice. The Board noted that the Fund's contractual and
actual management fees are lower than its peer group median although its total
expenses are higher than its peer group median.

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund, the extent to
which those economies of scale benefit the Fund's shareholders and the current
level of Fund assets in relation to the Fund's breakpoint schedule for its
management fees. The Board also noted the Fund's breakpoints, which are intended
to share economies of scale that may exist as the Fund grows with its
shareholders.

      BENEFITS TO THE MANAGER. The Board considered information regarding the
Manager's costs in serving as the Fund's investment adviser, including the costs
associated with the personnel and systems necessary to manage the Fund, and
information regarding the Manager's profitability from its relationship with the
Fund. The Board considered that the Manager must be able to pay and retain
experienced professional personnel at competitive rates to provide services to
the Fund and that maintaining the financial viability of the Manager is
important in order for the Manager to continue to provide significant services
to the Fund and its shareholders. In addition to considering the profits
realized by the Manager, the Board considered information regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates for services
provided.

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

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

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 01/31/2008, 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.
