Bonds rated by any nationally recognized statistical rating organization are
included in the equivalent Standard & Poor's rating category. As a general
matter, unrated bonds may be backed by mortgage liens or equipment liens on the
underlying property, and also may be guaranteed. Bonds which are backed by a
letter of credit or by other financial institutions or agencies may be assigned
an investment-grade rating by the Manager, which reflects the quality of the
guarantor, institution or agency. Unrated bonds may also be assigned a rating
when the issuer has rated bonds outstanding with comparable credit
characteristics, or when, in the opinion of the Manager, the bond itself
possesses credit characteristics which allow for rating. The unrated bonds in
the portfolio are predominantly smaller issuers which have not applied for a
bond rating. Only those unrated bonds which subsequent to purchase have not been
designated investment grade by the Manager are included in the "Not Rated"
category.

- --------------------------------------------------------------------------------
 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 advisor 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 by
 minor amounts due to each class having its own expenses directly attributable
 to that class. Classes A, B and C have separate distribution and/or service
 plans. Class B shares will automatically convert to Class A shares six years
 after the date of purchase.
    The following is a summary of significant accounting policies consistently
 followed by the Fund.

- --------------------------------------------------------------------------------
 SECURITIES VALUATION. Securities listed or traded on National Stock Exchanges
 or other domestic or foreign exchanges are valued based on the last sale price
 of the security traded on that exchange prior to the time when the Fund's
 assets are valued. Securities traded on NASDAQ are valued based on the closing
 price provided by NASDAQ prior to the time when the Fund's assets are valued.
 In the absence of a sale, the security is valued at the last sale price on the
 prior trading day, if it is within the spread of the closing bid and asked
 prices, and if not, at the closing bid price. Securities may be valued
 primarily using dealer-supplied valuations or a portfolio pricing service
 authorized by the Board of Trustees. Securities (including restricted
 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 foreign exchanges
 will be fair valued. Fair value is determined in good faith using consistently
 applied procedures under the supervision of the Board of Trustees. Short-term
 "money market type" debt securities with remaining maturities of sixty days or
 less are valued at amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
 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 intends to invest no more than 20% of its total assets in inverse
 floaters.


26 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND




 Inverse floaters amount to $61,093,924 as of January 31, 2004. Including the
 effect of leverage, inverse floaters represent 16.42% of the Fund's total
 assets as of January 31, 2004.

- --------------------------------------------------------------------------------
 SECURITY CREDIT RISK. The Fund invests in high-yield securities, which may be
 subject to a greater degree of credit risk, market fluctuations and loss of
 income and principal, and may be more sensitive to economic conditions than
 lower-yielding, higher-rated fixed-income securities. The Fund may acquire
 securities in default, and is not obligated to dispose of securities whose
 issuers subsequently default. As of January 31, 2004, securities with an
 aggregate market value of $17,875, representing less than 0.01% of the Fund's
 net assets, were in default.
    There are certain risks arising from geographic concentration in any State.
 Certain revenue or tax related events in a state may impair the ability of
 certain issuers of municipal securities to pay principal and interest on their
 obligations.

- --------------------------------------------------------------------------------
 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.
    As of January 31, 2004, the Fund had available for federal income tax
 purposes an estimated unused capital loss carryforward of $5,029,415 expiring
 by 2009. 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, 2004 and the year ended July 31,
 2003, the Fund used $2,132,798 and $23,695,023, respectively, of carryforward
 to offset capital gains realized.

 As of July 31, 2003, the Fund had available for federal income tax purposes
 unused capital loss carryforward as follows:

                              EXPIRING
                              ----------------------
                              2009        $7,162,213

- --------------------------------------------------------------------------------
 TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for
 the Fund's independent trustees. Benefits are based on years of service and
 fees paid to each trustee during the years of service. During the six months
 ended January 31, 2004, the Fund's projected benefit obligations were increase
 by $5,754 and payments of $7,869 were made to retired trustees, resulting in an
 accumulated liability of $90,439 as of January 31, 2004.

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



- --------------------------------------------------------------------------------
 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
 Fund. Under the plan, deferred amounts are treated as though equal dollar
 amounts had been invested in shares of the Fund or are invested in other
 Oppenheimer funds selected by the Trustee. Deferral of trustees' fees under the
 plan will not affect the net assets of the Fund, and will not materially affect
 the Fund's assets, liabilities or net investment income per share.
 Amounts will be deferred until distributed in accordance to the Plan.

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

- --------------------------------------------------------------------------------
 INVESTMENT INCOME. Interest income, which includes accretion of discount and
 amortization of premium, is accrued as earned.

- --------------------------------------------------------------------------------
 EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
 represents earnings on cash balances maintained by the Fund.

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

- --------------------------------------------------------------------------------
 OTHER. The preparation of financial statements in conformity with 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 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 were as follows:

 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 January 31, 2004, were
 $50,660,293 and $66,302,822, respectively.


- --------------------------------------------------------------------------------
 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 MANAGEMENT FEES. Management fees paid to the Manager were in accordance with
 the investment advisory agreement with the Fund which provides for a fee at an
 annual rate of 0.60% of the first $200 million of average annual net assets,
 0.55% of the next $100 million, 0.50% of the next $200 million, 0.45% of the
 next $250 million, 0.40% of the next $250 million, and 0.35% of average annual
 net assets over $1 billion. The Manager has voluntarily undertaken to limit its
 management fees to a maximum annual rate of 0.55% of average annual net assets
 for each class of shares. The Manager can withdraw that waiver at any time. The
 Manager voluntarily agreed to waive a portion of its advisory fee at an annual
 rate equal to 0.10% of each class's average daily net assets while the Fund's
 trailing one-year performance at the end of the preceding calendar quarter is
 in the fifth quintile of the Fund's Lipper peer group. The Manager will
 voluntarily waive a portion of its advisory fee at an annual rate equal to
 0.05% of each class's average daily net assets while the Fund's trailing
 one-year performance at the end of the preceding calendar quarter is in the
 fourth quintile of the Fund's Lipper peer group. The foregoing waiver may be
 amended or withdrawn by the Manager at any time.

- --------------------------------------------------------------------------------
 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, 2004, the
 Fund paid $129,040 to OFS for services to the Fund.

 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued
    OFS has voluntarily agreed to limit transfer and shareholder servicing agent
 fees for all classes, up to an annual rate of 0.35% of average net assets per
 class. This undertaking may be amended or withdrawn at any time.

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

- --------------------------------------------------------------------------------
 SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class
 A shares. It reimburses the Distributor for a portion of its costs incurred for
 services provided to accounts that hold Class A shares. Reimbursement is made
 quarterly 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 the fees it receives
 from the Fund to pay brokers, dealers and other financial institutions for
 personal services and account maintenance services they provide for their
 customers who 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 years. 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 for Class B and Class C shares to
 compensate the Distributor for its services and costs in distributing these
 shares and servicing accounts. Under the plans, the Fund pays the Distributor
 an annual asset-based sales charge of 0.75% per year on Class B shares and on
 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 the
 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 January 31, 2004 for Class B and Class C shares was $2,500,086 and
 $608,468, 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 table below for the period indicated.

- --------------------------------------------------------------------------------
 5. ILLIQUID SECURITIES
 As of January 31, 2004, investments in securities included issues that are
 illiquid. A security may be considered illiquid if it lacks a readily available
 market or if its valuation has not changed for a certain period of time. The
 Fund intends to invest no more than 15% of its net assets (determined at the
 time of purchase and reviewed periodically) in illiquid securities. The
 aggregate value of illiquid securities subject to this limitation as of January
 31, 2004 was $45,813,912, which represents 8.61% of the Fund's net assets.


- --------------------------------------------------------------------------------
 6. BANK BORROWINGS
 The Fund may borrow up to 33 1/3% of its total assets from a bank to purchase
 portfolio securities, or for temporary and emergency purposes. The purchase of
 securities with borrowed funds creates leverage in the Fund. The Fund has
 entered into an agreement which enables it to participate with certain other
 Oppenheimer funds in a committed, unsecured line of credit with a bank, which
 permits borrowings up to $540 million, collectively. Interest is charged to
 each fund, based on its borrowings, at a rate equal to the Federal Funds Rate
 plus 0.75%. The rate of the Federal Funds Rate plus 0.625% was effective from
 August 1, 2003 to November 8, 2003; thereafter, the rate is 0.75%. The Fund
 also pays a commitment fee equal to its pro rata share of the average
 unutilized amount of the credit facility at a rate of 0.09% per annum.
    The Fund had borrowings outstanding of $33,600,000 at January 31, 2004 at an
 interest rate of 1.8125%. For the six months ended January 31, 2004, the
 average monthly loan balance was $33,180,757 at an average daily interest rate
 of 1.721%. The Fund had gross borrowings and gross loan repayments of
 $117,100,000 and $130,300,000, respectively, during the six months ended
 January 31, 2004. The maximum amount of borrowings outstanding at any month-end
 was $46,800,000. The Fund paid commitment fees of $2,169 and interest of
 $290,945 during the six months ended January 31, 2004.

         At a meeting of the Board of Trustees of the registrant held on
February 18, 2004, the Board adopted (1) a policy that, should the Board
determine that a vacancy exists or is likely to exist on the Board, the
Governance Committee of the Board, which is comprised entirely of independent
trustees, shall consider any candidates for Board membership recommended by the
registrant's security holders and (2) a policy that security holders wishing to
submit a nominee for election to the Board may do so by mailing their submission
to the offices of OppenheimerFunds, Inc., Two World Financial Center, 225
Liberty Street - 11th Floor, New York, NY 10281-1008, to the attention of the
Chair of the Governance Committee. Prior to February 18, 2004, the Board did not
have a formalized policy with respect to consideration of security holder
nominees or a procedure by which security holders may make their submissions. In
addition to security holder nominees, the Governance Committee may also consider
nominees recommended by independent Board members or recommended by any other
Board members and is authorized under its Charter, upon Board approval, to
retain an executive search firm to assist in screening potential candidates.
Upon Board approval, the Governance Committee may also obtain legal, financial,
or other external counsel that may be necessary or desirable in the screening
process.

ITEM 10.  CONTROLS AND PROCEDURES

         (a)  Based on their evaluation of registrant's disclosure controls and
              procedures (as defined in rule 30a-2(c) under the Investment
              Company Act of 1940 (17 CFR 270.30a-2(c)) as of January 31, 2004,
              registrant's principal executive officer and principal financial
              officer found registrant's disclosure controls and procedures to
              provide reasonable assurances that information required to be
              disclosed by registrant in the reports that it files under the
              Securities Exchange Act of 1934 (a) is accumulated and
              communicated to registrant's management, including its principal
              executive officer and principal financial officer, to allow timely
              decisions regarding required disclosure, and (b) is recorded,
              processed, summarized and reported, within the time periods
              specified in the rules and forms adopted by the U.S. Securities
              and Exchange Commission.

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