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 1.8000.525.7048, 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. The Fund's maximum sales charge for Class A shares was lower prior to 1/31/86, so actual performance may have been higher. 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 "since inception" 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. 13 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND 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 any; 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, 2005. 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 Fund'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 Fund'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 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 14 | OPPENHEIMER CALIFORNIA MUNICIPAL 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.

Expenses are equal to the Fund's annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

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.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 32 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND 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 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 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 six years 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 business. 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. Corporate, government and municipal debt instruments having a remaining maturity in excess of sixty days and all mortgage-backed securities will be valued at the mean between the "bid" and "asked" prices. 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. Foreign and domestic 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 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). 33 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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 will invest no more than 20% of its total assets in inverse floaters. Inverse floaters amount to $66,484,673 as of January 31, 2005. Including the effect of leverage, inverse floaters represent 16.45% of the Fund's total assets as of January 31, 2005. - -------------------------------------------------------------------------------- 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, 2005, securities with an aggregate market value of $21,500, 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. 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, 2005, the Fund had available for federal income tax purposes an estimated capital loss carryforward of $3,754,219 expiring by 2013. This estimated capital loss carryforward represents carryforward as of the end of the last fiscal year, increased for losses deferred under tax accounting rules to the current fiscal year and is increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. As of January 31, 2005, it is estimated that the Fund will utilize $921,341 of capital 34 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND loss carryforward to offset realized capital gains. During the year ended July 31, 2004, the Fund did utilize $2,486,648 of capital loss carryforward to offset realized capital gains. As of July 31, 2004, the Fund had available for federal income tax purposes an unused capital loss carryforward as follows: EXPIRING -------------------------- 2009 $4,675,560 - -------------------------------------------------------------------------------- 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, 2005, the Fund's projected benefit obligations were increased by $2,513 and payments of $7,347 were made to retired trustees, resulting in an accumulated liability of $91,396 as of January 31, 2005. 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. 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 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. - -------------------------------------------------------------------------------- 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 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. 35 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued SECURITY TRANSACTIONS. Security transactions are recorded on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost. - -------------------------------------------------------------------------------- OTHER. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period.

(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 all of those fees to pay dealers, brokers, banks and other financial institutions quarterly 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 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 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% per year on Class B and Class C shares. The Distributor also receives a service fee of up to 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.

ILLIQUID SECURITIES As of January 31, 2005, investments in securities included issues that are illiquid.

The Fund will not invest more than 15% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid securities. - -------------------------------------------------------------------------------- 6. BORROWINGS The Fund can borrow money from banks in amounts up to 33 1/3% 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. Until terminated on January 21, 2005, the Fund had entered into an agreement which enabled it to participate with certain other Oppenheimer funds in a committed, unsecured line of credit with a bank, which permitted borrowings up to $540 million, collectively. Interest was charged to each fund, based on its borrowings, at a rate equal to the Federal Funds Rate plus 0.75%. The Fund also paid 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. Effective January 21, 2005 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 $800 million, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. 38 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (2.4038% as of January 31, 2005). The Fund pays additional fees of 0.30% per annum on its outstanding borrowings to manage and administer the facility and is allocated its pro-rata share of a 0.13% per annum commitment fee for a liquidity backstop facility with respect to the $800 million facility size. For the six month period ended January 31, 2005, the average daily loan balance was $12,279,891 at an average daily interest rate of 2.601%. The Fund had borrowings outstanding of $7,500,000 at January 31, 2005 at an interest rate of 2.4038%. The Fund had gross borrowings and gross loan repayments of $38,700,000 and $61,600,000, respectively, during the six months ended January 31, 2005. The maximum amount of borrowings outstanding at any month-end during the six month period ended January 31, 2005 was $25,100,000. The Fund paid $3,357 in fees and $139,062 in interest during the six months ended January 31, 2005. - -------------------------------------------------------------------------------- 7. LITIGATION A consolidated amended complaint has been filed as putative derivative and class actions against the Manager, OFS and the Distributor (collectively, the "Oppenheimer defendants"), as well as 51 of the Oppenheimer funds (as "Nominal Defendants") including the Fund, 31 present and former Directors or Trustees and 9 present and former officers of the funds. This complaint, initially filed in the U.S. District Court for the Southern District of New York on January 10, 2005 and amended on March 4, 2005, consolidates into a single action and amends six individual previously-filed putative derivative and class action complaints. Like those prior complaints, the complaint alleges that the Manager charged excessive fees for distribution and other costs, improperly used assets of the funds in the form of directed brokerage commissions and 12b-1 fees to pay brokers to promote sales of the funds, and failed to properly disclose the use of assets of the funds to make those payments in violation of the Investment Company Act of 1940 and the Investment Advisers Act of 1940. Also, like those prior complaints, the complaint further alleges that by permitting and/or participating in those actions, the Directors/Trustees and the Officers breached their fiduciary duties to shareholders of the funds under the Investment Company Act of 1940 and at common law. The complaint seeks unspecified compensatory and punitive damages, rescission of the funds' investment advisory agreements, an accounting of all fees paid, and an award of attorneys' fees and litigation expenses. The Oppenheimer defendants believe that the allegations contained in the Complaints are without merit and that they, the funds named as Nominal Defendants, and the Directors/Trustees of those funds have meritorious defenses against the claims asserted. The Oppenheimer defendants intend to defend these lawsuits vigorously and to contest any claimed liability. The Oppenheimer defendants believe that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them and that no estimate can yet be made with any degree of certainty as to the amount or range of any potential loss. 39 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; UPDATES TO STATEMENTS OF INVESTMENTS Unaudited - -------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.
