Percentages are as of January 31, 2006, and are dollar-weighted based on the total market value of investments. Securities rated by any rating organization are included in the equivalent S&P rating category. The allocation includes rated securities and those not rated by a national rating organization but to which the ratings above have been assigned by the Manager for internal purposes as being comparable, in the Manager's judgment, to securities rated by a rating agency in the same category. - -------------------------------------------------------------------------------- 13 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND 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. 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. 14 | 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, 2006. ACTUAL EXPENSES. The "actual" lines of the table provide information about actual account values and actual expenses. You may use the information on this line for the class of shares you hold, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the "actual" line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the table provide information about hypothetical account values and hypothetical expenses based on the 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 15 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND FUND EXPENSES - -------------------------------------------------------------------------------- the Statement of Additional Information). Therefore, the "hypothetical" lines of the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES ACCOUNT ACCOUNT PAID DURING VALUE VALUE 6 MONTHS ENDED (8/1/05) (1/31/06) JANUARY 31, 2006 - -------------------------------------------------------------------------------- Class A Actual $1,000.00 $1,019.00 $5.00 - -------------------------------------------------------------------------------- Class A Hypothetical 1,000.00 1,020.27 5.00 - -------------------------------------------------------------------------------- Class B Actual 1,000.00 1,014.90 9.03 - -------------------------------------------------------------------------------- Class B Hypothetical 1,000.00 1,016.28 9.04 - -------------------------------------------------------------------------------- Class C Actual 1,000.00 1,015.10 8.88 - -------------------------------------------------------------------------------- Class C Hypothetical 1,000.00 1,016.43 8.88 Hypothetical assumes 5% annual return before expenses. 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, 2006 are as follows: CLASS EXPENSE RATIOS - ---------------------------- Class A 0.98% - ---------------------------- Class B 1.77 - ---------------------------- Class C 1.74 - -------------------------------------------------------------------------------- 16 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND STATEMENT OF INVESTMENTS January 31, 2006 / Unaudited - -------------------------------------------------------------------------------- PRINCIPAL VALUE AMOUNT COUPON MATURITY SEE NOTE 1 - -------------------------------------------------------------------------------------------------------------------------- MUNICIPAL BONDS AND NOTES--101.8% - -------------------------------------------------------------------------------------------------------------------------- CALIFORNIA--90.8% $ 3,025,000 ABAG Finance Authority for NonProfit Corporations (Channing House) 1 5.500% 02/15/2029 $ 3,130,331 - -------------------------------------------------------------------------------------------------------------------------- 1,000,000 ABAG Finance Authority for NonProfit Corporations (Schools of Sacred Heart) 1 6.450 06/01/2030 1,065,660 - -------------------------------------------------------------------------------------------------------------------------- 90,000 ABAG Finance Authority for NonProfit Corporations COP 6.000 08/15/2020 91,948 - -------------------------------------------------------------------------------------------------------------------------- 450,000 ABAG Finance Authority for NonProfit Corporations COP (American Baptist Homes of the West) 5.750 10/01/2017 454,437 - -------------------------------------------------------------------------------------------------------------------------- 250,000 ABAG Finance Authority for NonProfit Corporations COP (Lytton Gardens) 6.000 02/15/2019 261,373 - -------------------------------------------------------------------------------------------------------------------------- 440,000 ABAG Finance Authority for NonProfit Corporations COP (O'Connor Woods) 6.200 11/01/2029 475,768 - -------------------------------------------------------------------------------------------------------------------------- 4,300,000 ABAG Finance Authority for NonProfit Corporations COP (Redwood Senior Homes & Services) 1 6.125 11/15/2032 4,623,962 - -------------------------------------------------------------------------------------------------------------------------- 55,000 Adelanto Improvement Agency, Series B 5.500 12/01/2023 55,387 - -------------------------------------------------------------------------------------------------------------------------- 50,000 Adelanto Public Financing Authority 6.300 09/01/2028 51,111 - -------------------------------------------------------------------------------------------------------------------------- 5,295,000 Agua Mansa Industrial Growth Association Special Tax 6.500 09/01/2033 5,603,010 - -------------------------------------------------------------------------------------------------------------------------- 1,500,000 Alameda COP 5.750 12/01/2021 1,558,875 - -------------------------------------------------------------------------------------------------------------------------- 200,000 Alameda Public Financing Authority 5.450 09/02/2014 204,172 - -------------------------------------------------------------------------------------------------------------------------- 1,695,000 American Canyon Financing Authority (American Canyon Road East) 5.100 09/02/2035 1,651,727 - -------------------------------------------------------------------------------------------------------------------------- 4,000,000 Anaheim Public Financing Authority RITES 1,2 9.520 3 12/28/2018 4,607,960 - -------------------------------------------------------------------------------------------------------------------------- 3,255,000 Apple Valley Redevel.

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. 30 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND - -------------------------------------------------------------------------------- INDUSTRY CONCENTRATIONS January 31, 2006 -

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 38 | 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 may be valued primarily using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Trustees. Securities listed or traded on National Stock Exchanges or other domestic 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 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 will be valued at the mean between the "bid" and "asked" prices. Futures contracts traded on a commodities or futures exchange will be valued at the final settlement price or official closing price on the principal exchange as reported by such principal exchange at its trading session ending at, or most recently prior to, the time when the Fund's assets are valued. Securities (including restricted securities) for which market quotations are not readily available are valued at their fair value. Foreign and domestic securities whose 39 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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). - -------------------------------------------------------------------------------- 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 not invest more than 20% of its total assets in inverse floaters. Inverse floaters amount to $73,649,018 as of January 31, 2006, which represents 6.50% of the Fund's total assets. - -------------------------------------------------------------------------------- SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis or forward commitment can take place up to ten days or more after the trade date. Normally the settlement date occurs within six months after the trade date; however, the Fund may, from time to time, purchase securities whose settlement date extends six months or more beyond 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 Fund maintains internally designated assets with a market value equal to or greater than the amount of its purchase commitments. The purchase of securities on a when-issued basis or forward commitment may increase the volatility of the Fund's net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. 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, 2006, the Fund had purchased $3,085,374 of securities issued on a when-issued basis or forward commitment. - -------------------------------------------------------------------------------- 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, 2006, securities with an aggregate market value of $246,506, representing 0.02% 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. 40 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND - -------------------------------------------------------------------------------- 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, 2006, it is estimated that the Fund will utilize $3,173,279 of capital loss carryforward to offset realized capital gains. During the year ended July 31, 2005, the Fund utilized $1,502,281 of capital loss carryforward to offset capital gains realized in that fiscal year. As of July 31, 2005, the Fund had available for federal income tax purposes an unused capital loss carryforward as follows: EXPIRING ------------------------------- 2009 $3,173,279 - -------------------------------------------------------------------------------- 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, 2006, the Fund's projected benefit obligations were decreased by $211 and payments of $8,353 were made to retired trustees, resulting in an accumulated liability of $82,572 as of January 31, 2006. The Board of Trustees has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the 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 41 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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 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. - -------------------------------------------------------------------------------- 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 U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. 42 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND - -------------------------------------------------------------------------------- 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: SIX MONTHS ENDED JANUARY 31, 2006 YEAR ENDED JULY 31, 2005 SHARES AMOUNT SHARES AMOUNT - -------------------------------------------------------------------------------------------- CLASS A Sold 26,600,318 $ 304,726,068 19,938,576 $ 223,516,947 Dividends and/or distributions reinvested 1,029,449 11,786,316 1,431,372 15,844,672 Redeemed (4,522,672) (51,669,087) (6,371,483) (70,372,344) ------------------------------------------------------------ Net increase 23,107,095 $ 264,843,297 14,998,465 $ 168,989,275 ============================================================ - ------------------------------------------------------------------------------------------- CLASS B Sold 930,579 $ 10,663,999 1,070,121 $ 11,925,943 Dividends and/or distributions reinvested 72,461 830,569 164,749 1,816,688 Redeemed (733,482) (8,410,885) (2,471,135) (27,100,401) ------------------------------------------------------------ Net increase (decrease) 269,558 $ 3,083,683 (1,236,265) $ (13,357,770) ============================================================ - -------------------------------------------------------------------------------------------- CLASS C Sold 6,324,370 $ 72,360,431 4,514,407 $ 50,858,939 Dividends and/or distributions reinvested 121,732 1,390,879 106,662 1,181,896 Redeemed (1,022,521) (11,671,831) (722,327) (7,949,586) ------------------------------------------------------------ Net increase 5,423,581 $ 62,079,479 3,898,742 $ 44,091,249 ============================================================ - -------------------------------------------------------------------------------- 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, 2006, were as follows: PURCHASES SALES - -------------------------------------------------------------------------------- Investment securities $315,056,406 $192,034,946 - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 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, 2006, the Fund paid $163,138 to OFS for services to the Fund. 43 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued 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 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 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% on Class B and Class C shares. The Distributor also receives a service fee of up to 0.25% 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 plan at January 31, 2006 for Class B and Class C shares were $2,396,192 and $2,031,946, 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.

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 is expected to remain in effect indefinitely, however, it 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, 2006, 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 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 the applicable footnote on the Statement of Investments. - -------------------------------------------------------------------------------- 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 Fund has 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. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (4.4016% as of January 31, 2006). 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 months ended January 31, 2006, the average daily loan balance was $39,802,717 at an average daily interest rate of 3.911%. The Fund had borrowings outstanding of $43,700,000 at January 31, 2006 at an interest rate of 4.4016%. The Fund had gross borrowings and gross loan repayments of $263,200,000 and $287,100,000, respectively, during the six months ended January 31, 2006. The maximum amount of borrowings outstanding at any month-end during the six months ended January 31, 2006 was $79,400,000. The Fund paid $72,866 in fees and $691,321 in interest during the six months ended January 31, 2006. 45 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 7. LITIGATION A complaint was filed as a putative class action against the Manager and OFS (and other defendants) in the U.S. District Court for the Southern District of New York on January 10, 2005 and was amended on March 4, 2005. Seven of the eight counts in the complaint, including claims against certain of the Oppenheimer funds including the Fund, as nomi-nal defendants, and against certain present and former Directors, Trustees and officers of the funds, and the Distributor, as defendants, were dismissed with prejudice, under a court order dated March 10, 2006, in response to a motion to dismiss the suit that had been filed by the defendants. The remaining count against the Adviser Defendants alleges, among other things, that the defendants charged excessive fees in violation of section 36(b) of the Investment Company Act of 1940. The plaintiffs seek unspecified damages, an accounting of all fees paid, and an award of attorneys' fees and litigation expenses. The Adviser Defendants believe that the claims asserted in the remaining count under this lawsuit are without merit, and intend to defend the suit vigorously and contest any claimed liability. They 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. 46 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND REPORT OF SHAREHOLDER MEETING Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- On August 17, 2005, a shareholder meeting of the Oppenheimer California Municipal Fund was held at which the eleven Trustees identified below were elected (Proposal No. 1).

A description of the Fund's Portfolio Proxy Voting Policies and Procedures is available (i) without charge, upon request, by calling the Fund toll-free at 1.800.525.7048, (ii) on the Fund's website at www.oppenheimerfunds.com, and (iii) on the SEC's website at www.sec.gov.

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 on the nature and extent of the services provided to the Fund and information regarding the Manager's key personnel that 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 the activities of, all administrative and clerical personnel that 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. 49 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited / Continued - -------------------------------------------------------------------------------- QUALITY OF SERVICES. The Board also considered the quality of the services provided and the quality of the Manager's resources that are available to the Fund. The Board took account of the facts 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 and the Manager's Municipal Bond investment team and analysts. Mr. Fielding has had over 28 years of experience managing tax exempt and fixed income investments. The Board members also considered their experiences with the Manager and its officers and other personnel through their service as directors or trustees 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 it also reviews at other times during the year 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 as a result of 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 performance of the Fund and the Manager at each Board meeting, including comparative performance information. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund's historical performance to relevant market indices and to the performance of other California municipal debt funds advised by the Manager and other investment advisers. The Board noted that the Fund's one-year, three-year, five-year and ten-year performance was better than its peer group average. MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the Manager and its affiliates and the other expenses borne by the Fund. The Board also evaluated the comparability of the fees charged and the services provided to the Fund to those of 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 agreed to voluntarily waive a portion of its management fee such that it will not exceed 0.55% of average annual net assets for each class of shares. The Board 50 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND noted that the Fund's contractual and actual management fees and its total expenses were higher than its peer group average. ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may realize economies of scale in managing and supporting the Fund, to what extent those economies of scale benefit the Fund shareholders and the current level of Fund assets. 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. PROFITS AND OTHER 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. The Board also 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 advisory 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 advisory agreement, including the management fee, in light of all of the surrounding circumstances. 51 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND ITEM 2.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS 1. The Fund's Governance Committee (the "Committee") will evaluate potential Board candidates to assess their qualifications. The Committee shall have the authority, upon approval of the Board, to retain an executive search firm to assist in this effort. The Committee may consider recommendations by business and personal contacts of current Board members and by executive search firms which the Committee may engage from time to time and may also consider shareholder recommendations. The Committee may consider the advice and recommendation of the Funds' investment manager and its affiliates in making the selection. 2. The Committee shall screen candidates for Board membership. The Committee has not established specific qualifications that it believes must be met by a trustee nominee. In evaluating trustee nominees, the Committee considers, among other things, an individual's background, skills, and experience; whether the individual is an "interested person" as defined in the Investment Company Act of 1940; and whether the individual would be deemed an "audit committee financial expert" within the meaning of applicable SEC rules. The Committee also considers whether the individual's background, skills, and experience will complement the background, skills, and experience of other nominees and will contribute to the Board. There are no differences in the manner in which the Committee evaluates nominees for trustees based on whether the nominee is recommended by a shareholder. 3. The Committee may consider nominations from shareholders for the Board at such times as the Committee meets to consider new nominees for the Board. The Committee shall have the sole discretion to determine the candidates to present to the Board and, in such cases where required, to shareholders. Recommendations for trustee nominees should, at a minimum, be accompanied by the following: o the name, address, and business, educational, and/or other pertinent background of the person being recommended; o a statement concerning whether the person is an "interested person" as defined in the Investment Company Act of 1940; o any other information that the Funds would be required to include in a proxy statement concerning the person if he or she was nominated; and o the name and address of the person submitting the recommendation and, if that person is a shareholder, the period for which that person held Fund shares. The recommendation also can include any additional information which the person submitting it believes would assist the Committee in evaluating the recommendation. 4. Shareholders should note that a person who owns securities issued by Massachusetts Mutual Life Insurance Company (the parent company of the Funds' investment adviser) would be deemed an "interested person" under the Investment Company Act of 1940. In addition, certain other relationships with Massachusetts Mutual Life Insurance Company or its subsidiaries, with registered broker-dealers, or with the Funds' outside legal counsel may cause a person to be deemed an "interested person." 5. Before the Committee decides to nominate an individual as a trustee, Committee members and other directors customarily interview the individual in person. In addition, the individual customarily is asked to complete a detailed questionnaire which is designed to elicit information which must be disclosed under SEC and stock exchange rules and to determine whether the individual is subject to any statutory disqualification from serving as a trustee of a registered investment company. ITEM 11. CONTROLS AND PROCEDURES. Based on their evaluation of the registrant's disclosure controls and procedures (as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR 270.30a-3(c)) as of January 31, 2006, the registrant's principal executive officer and principal financial officer found the registrant's disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by the registrant in the reports that it files under the Securities Exchange Act of 1934 (a) is accumulated and communicated to registrant's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure, and (b) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the U.S. Securities and Exchange Commission. There have been no changes in the registrant's internal controls over financial reporting that occurred during the registrant's second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
