FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JULY 31, 2007, FOLLOWED BY A
GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. We are pleased to report that
Oppenheimer California Municipal Fund distributed high levels of tax-free income
to its shareholders during this reporting period, outperforming many
fixed-income alternatives on an after-tax basis. As of July 31, 2007,
Oppenheimer California Municipal Fund's Class A shares provided a distribution
yield of 4.71% at net asset value. Lipper Inc.--an independent mutual fund
rating service--reported an average distribution yield of 3.92% among the 119
funds in its California Municipal Debt Funds category as of the same date. 1

      Tax-free income generated 100% of the Fund's positive total return for the
reporting period, providing significant benefit to our yield-oriented investors.
The Fund's Class A shares generated a 1-year total return of 4.67% without sales
charge. By comparison, the Lehman Brothers Municipal Bond Index produced a total
return of 4.27% in the same period. On July 31, 2007, the Fund was ranked in the
top 2% of funds in its Lipper category in total return for periods of 1, 3, 5
and 10 years. 2 These results clearly demonstrate how the Fund's income-oriented
approach continued to provide significant benefit to our investors in the past
12 months.

      Early in this reporting period, a marked shift in the risk-return levels
of bonds for sale made lower-grade offerings less attractive than usual. As a
result, the Fund's newer purchases included many high-grade investments, which
generally offer lower yields than their low-grade counterparts. This development
forced the Fund to lower its dividend to 4.5 cents per Class A share, from 4.9
cents, beginning with the September distribution. Distributions for other share
classes were adjusted accordingly. The monthly distribution was unchanged for
the remainder of the reporting period, during which the Fund distributed 54.4
cents per Class A share, including a small amount of taxable income.

1. Lipper Inc. Lipper calculations do not include sales charges which, if
included, would reduce results.

2. Lipper Inc. As of July 31, 2007, Lipper Inc. ranked Oppenheimer California
Municipal Fund 2nd among 116 funds for the past year,1st among 104 funds for the
past 3 years,1st among 92 funds for the past 5 years and 1st among 70 funds for
the past 10 years in its California Municipal Debt Funds category. Lipper
rankings are based on total returns, but do not consider sales charges. Lipper
rankings are for the A share class only; other classes may have different
performance characteristics. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

      The Fund's holdings in tobacco Master Settlement Agreement (MSA) bonds
continued to provide significant benefit this reporting period. These so-called
tobacco bonds are backed by state and/or U.S. territory proceeds from a national
litigation settlement with tobacco manufacturers. At the end of this reporting
period, MSA-backed tobacco bonds accounted for one-quarter of Fund investments
and comprised the Fund's largest industry category.

      This sector contributed strongly to the Fund's total return this reporting
period, which included two large pre-refundings that elevated bond prices.
Tobacco manufacturers continue to face litigation, but we believe the risks have
been overstated. In the history of MSA-backed tobacco bonds, interest payments
and scheduled payments of principal on the bonds held by our funds have never
been interrupted--and many bonds have repaid principal earlier than their
scheduled final maturity.

      Some recent courtroom decisions, nonetheless, are worth noting. Tobacco
manufacturers received good news in August 2006 when a judge ruled that she
could not authorize financial remedies, despite a finding that federal
racketeering laws had been violated. In November 2006, the U.S. Supreme Court
declined to review a 2005 ruling by the Illinois Supreme Court that reversed a
$10.1 billion judgment against Philip Morris USA. Late in this reporting period,
a federal judge in the Southern District of New York ruled that a smoker's claim
for punitive damages cannot be awarded because New York State, which had sued
the tobacco industry in 1997, ultimately agreed to participate in the MSA.

      The Fund's current weighting in MSA-backed bonds reflects our belief that
these bonds can continue to help the Fund deliver high levels of tax-free
income.

      In this reporting period, the Fund continued to favor bonds issued to
finance the infrastructure of new real estate development projects. The credit
structure of these Special Tax and Special Assessment bonds (known as "dirt
bonds") are advantageous, we believe, because the payments that secure the bonds
are on parity with real estate taxes. Additionally, the responsibility for
servicing the debt passes to all subsequent property owners as the land is
developed and subdivided. Thus, as the number of owners increases, the risk
bondholders face decreases. Further, the fear of foreclosure leads most property
owners to stay current with their debt service payments--to the benefit of the
Fund.

      In all, Special Tax and Special Assessment bonds constituted nearly
one-quarter of the portfolio's market value as of July 31, 2007, included
largely attractive holdings and contributed positively to total return. The
Fund's small position in bonds issued to finance infrastructure development in
the Roripaugh Community Facilities District, in Temecula,


                   16 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



California, however, was a concern this reporting period. The construction
timeline was delayed and various building permits were withheld when a financial
institution affiliated with both the lead developer and a participating home
builder filed for bankruptcy protection this reporting period. The prices of the
bonds held by the Fund fell as a result and detracted from overall performance.
All scheduled payments were made this reporting period, with the affiliated
developers using a letter of credit to offset any payment shortfalls. We expect
payments to remain timely after the financial institution emerges from
bankruptcy protection and construction resumes. Importantly, we continue to
believe that our tax-free investments in "dirt bonds" represent valuable and
relatively low-risk opportunities to participate in the today's challenging
housing market.

      Credit spreads were relatively stable this reporting period. AAA- and
AA-rated securities continued to represent a significant share of the Fund's
market value as of July 31, 2007, as Fund managers scoured the municipal markets
for securities that offered an attractive balance of risk and reward. At the end
of the reporting period, more than 80% of the Fund's portfolio consisted of
investment-grade securities, and the Fund's average credit quality was A.

      Including the effects of leverage, the Fund increased its position this
reporting period in municipal inverse-floating-rate securities, which are
tax-exempt securities whose interest payments move inversely to changes in
short-term interest rates. Most of the Fund's new investments in these bonds
were PLNs (percentage of LIBOR notes), which are designed to have minimal (if
any) reaction to interest rate fluctuations. Additionally, PLNs reset quarterly
and, to the benefit of the Fund, these "inverse floaters" offered yields that
were higher than market averages during this reporting period.

      During this reporting period, the U.S. Supreme Court announced that it
would hear DEPARTMENT OF REVENUE (KENTUCKY) V. DAVIS this fall or early in 2008,
with a ruling to follow. The question posed in the case is whether Kentucky can
tax the income that state residents earn on out-of-state municipal securities if
the income that residents earn from in-state municipal securities is exempt from
taxation. While the Court's decision could have implications for other states,
exemption from federal taxes, which provides investors with the greatest
benefit, is not in question. We cannot confidently predict what the Court will
decide. However, we will continue to serve our shareholders by focusing on how
best to create tax-free yield advantages in any current and future market
scenario. We remain committed to helping fixed-income investors achieve their
financial goals for tax-free income and will continue to offer a full complement
of municipal bond funds to serve our shareholders' diverse needs.

      Our approach to municipal bond investing is flexible and responsive to
market conditions; our strategies are intended to balance many different types
of risk to reduce overall

FUND PERFORMANCE DISCUSSION

portfolio risk. Shareholders should note that market conditions during this
reporting period did not affect the Fund's overall investment strategies or
cause it to pay any capital gain distributions. In closing, we believe that the
Fund's structure and composition as well as our time-tested strategies will
continue to benefit long-term investors through interest rate and economic
cycles.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until July 31, 2007. In the case of Class A, Class B and Class C
shares, performance is measured over a ten-year period. The Fund's performance
reflects the deduction of the maximum initial sales charge on Class A shares,
the applicable contingent deferred sales charge on Class B and Class C shares,
and reinvestments of all dividends and capital gains distributions. Past
performance cannot guarantee future results.

      The Fund's performance is compared to the performance of the Lehman
Brothers Municipal Bond Index, an unmanaged index of a broad range of investment
grade municipal bonds that is widely regarded as a measure of the performance of
the general municipal bond market. Index performance reflects the reinvestment
of income but does not consider the effect of transaction costs, and none of the
data in the graphs shows the effect of taxes. The Fund's performance reflects
the effects of the Fund's business and operating expenses. While index
comparisons may be useful to provide a benchmark for the Fund's performance, it
must be noted that the Fund's investments are not limited to the investments in
the index.

GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,

REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 4.75%; FOR CLASS B SHARES, AND THE
CONTINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS C
SHARES, THE 1% CONTINGENT DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD. BECAUSE
CLASS B SHARES CONVERT TO CLASS A SHARES 72 MONTHS AFTER PURCHASE, THE 10-YEAR
RETURN FOR CLASS B USES CLASS A PERFORMANCE FOR THE PERIOD AFTER CONVERSION. SEE

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

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

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

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

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

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

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

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if 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 July 31, 2007.

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 the
Statement of Additional Information). Therefore, the "hypothetical" lines of the

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 181/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended July 31, 2007 are as follows:

CLASS      EXPENSE RATIOS
- -------------------------
Class A         1.31%
- -------------------------
Class B         2.10
- -------------------------
Class C         2.07

The expense ratios reflect reduction to custodian expenses. The "Financial
Highlights" tables in the Fund's financial statements, included in this report,
also show the gross expense ratios, without such waivers or reimbursements and
reduction to custodian expenses, if applicable.

NOTES TO FINANCIAL STATEMENTS

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(R) 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. Options are
valued daily based upon the last sale price on the principal exchange on which
the option is traded. Securities (including restricted securities) for which
market quotations are not readily available are valued at their fair value.

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. Investments in open-end
registered investment companies (including affiliated funds) are valued at that
fund's net asset value. 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 $152,576,844 as of July 31, 2007, which represents
5.11% of the Fund's total assets.

     Certain inverse floating rate securities are created when the Fund
purchases and subsequently transfers a municipal bond security (the "municipal
bond") to a broker dealer. The municipal bond is typically a fixed rate
security. The broker dealer (the "sponsor") creates a trust (the "Trust") and
deposits the municipal bond. The Trust issues short-term floating rate notes
available to third parties and a residual interest in the municipal bond
(referred to as an "inverse floating rate security") to the Fund. The terms of
these inverse floating rate securities grant the Fund the right to require that
the Trust issuing the inverse floating rate security compel a tender of the
short-term floating rate notes to facilitate the Fund's repurchase of the
underlying municipal bond. Following such a request, the Fund pays the sponsor
the principal amount due to the holders of the short-term floating rate notes
issued by the Trust and exchanges the inverse floating rate security for the
underlying municipal bond. These transactions are considered secured borrowings
for financial reporting purposes. As a result of such accounting treatments, the
Fund includes the municipal bond position on its Statement of Investments (but
does not separately include the inverse floating rate securities received). The
Fund also includes the value of the municipal bond and a payable amount equal to
the short-term floating rate notes issued by the Trust on its Statement of
Assets and Liabilities. The interest rates on these short-term floating rate
notes reset periodically, usually weekly. The holders of these short-term
floating rate notes have the option to tender their investment, to the sponsor
or the Trust's liquidity provider, for redemption at par at each reset date.
Income from the municipal bond position and the interest expense on the payable
for the short-term floating rate notes issued by the Trust are recorded on the
Fund's Statement of Operations. At July 31, 2007, municipal bond holdings with a
value of $605,835,138 shown on the Fund's Statement of Investments are held


                   60 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



by such Trusts and serve as collateral for the $460,930,000 in short-term
floating rate notes issued and outstanding at that date.

At July 31, 2007, the Fund's residual exposure to these types of inverse
floating rate securities were as follows:

1. SIGNIFICANT ACCOUNTING POLICIES Continued

The Fund enters into shortfall and forbearance agreements with the sponsors of
certain inverse floaters held by the Fund. These agreements commit the Fund to
reimburse the sponsor of the inverse floater, in certain circumstances, for the
amount of the difference between the liquidation value of the underlying
security (which is the basis of the inverse floater) and the principal amount
due to the holders of the floating rate notes issued by the Trust in conjunction
with the inverse floating rate security. Under the standard terms of an inverse
floating rate security, absent such a shortfall and forbearance agreement, the
Fund would not be required to make such a reimbursement. The Manager monitors
the Fund's potential exposure with respect to these agreements on a daily basis
and intends to take action to terminate the Fund's investment in such inverse
floating rate securities, if it deems it appropriate to do so. As of July 31,
2007, in addition to the exposure detailed in the preceding table, the Fund's
maximum exposure under such agreements is estimated at approximately
$13,500,000.

- --------------------------------------------------------------------------------
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 take place generally at least 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 July 31, 2007, the Fund had purchased $4,756,000 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 July 31, 2007, securities with an aggregate
market value of $3,043,688, representing 0.12% 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.

The tax components of capital shown in the following table represent
distribution requirements the Fund must satisfy under the income tax
regulations, losses the Fund may be able to offset against income and gains
realized in future years and unrealized appreciation or depreciation of
securities and other investments for federal income tax purposes.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of July 31, 2007 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is attributable to the tax deferral of losses
or tax realization of financial statement unrealized gain or loss.

             Federal tax cost of securities       $2,413,483,247
                                                  ==============

             Gross unrealized appreciation        $   59,803,301
             Gross unrealized depreciation           (22,355,174)
                                                  --------------
             Net unrealized appreciation          $   37,448,127
                                                  ==============

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan (the
"Plan") for the Fund's independent trustees. Benefits are based on years of
service and fees paid to each trustee during their period of service. The Plan
was frozen with respect to adding new participants effective December 31, 2006
(the "Freeze Date") and existing Plan Participants as of the Freeze Date will
continue to receive accrued benefits under the Plan. Active independent trustees
as of the Freeze Date have each elected a distribution method with respect to
their benefits under the Plan. During the year ended July 31, 2007, the Fund's
projected benefit obligations were increased by $84,464 and payments of $42,688
were made to retired trustees, resulting in an accumulated liability of $142,781
as of July 31, 2007.

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

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
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.


                   64 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



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

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

to OFS for services to the Fund.

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


                   66 | OPPENHEIMER CALIFORNIA MUNICIPAL FUND



- --------------------------------------------------------------------------------
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
periods. Fees incurred by the Fund under the Plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B AND CLASS C SHARES. The Fund has
adopted Distribution and Service Plans 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% per year
under each plan. If either the Class B or Class C plan is terminated by the Fund
or by the shareholders of a class, the Board of Trustees and its independent
trustees must determine whether the Distributor shall be entitled to payment
from the Fund of all or a portion of the service fee and/or asset-based sales
charge in respect to shares sold prior to the effective date of such
termination. The Distributor determines its uncompensated expenses under the
plan at calendar quarter ends. The Distributor's aggregate uncompensated
expenses under the plan at June 30, 2007 for Class B and Class C shares were
$2,848,334 and $6,300,812, respectively. Fees incurred by the Fund under the
plans are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

     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 July 31, 2007, 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 $900 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 (5.2958% as of July 31, 2007). 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 $900
million facility size.

     For the year ended July 31, 2007, the average daily loan balance was
$34,926,849 at an average daily interest rate of 5.286%. The Fund had borrowings
outstanding of $24,100,000 at July 31, 2007 at an interest rate of 5.2958%. The
Fund had gross borrowings and gross loan repayments of $766,600,000 and
$762,800,000, respectively, during the year ended July 31, 2007. The maximum
amount of borrowings outstanding at any month-end during the year ended July 31,
2007 was $122,000,000. The Fund paid $137,359 in fees and $1,551,891 in interest
during the year ended July 31, 2007.

7. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Fund's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Fund's tax return will
be ultimately sustained. A tax liability and expense must be recorded in respect
of any tax position that, in Management's judgment, will not be fully realized.
FIN 48 is effective for fiscal years beginning after December 15, 2006. As of
July 31, 2007, the Manager has evaluated the implications of FIN 48 and does not
currently anticipate a material impact to the Fund's financial statements. The
Manager will continue to monitor the Fund's tax positions prospectively for
potential future impacts.

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

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER CALIFORNIA MUNICIPAL FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer California Municipal Fund, including the statement of investments,
as of July 31, 2007, and the related statements of operations and cash flows for
the year then ended, the statements of changes in net assets for each of the
years in the two-year period then ended, and the financial highlights for each
of the years in the five-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 2007, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer California Municipal Fund as of July 31, 2007, the results of its
operations and its cash flows for the year then ended, the changes in its net
assets for each of the years in the two-year period then ended, and the
financial highlights for each of the years in the five-year period then ended,
in conformity with U.S. generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2008, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2007. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

     None of the dividends paid by the Fund during the fiscal year ended July
31, 2007 are eligible for the corporate dividend-received deduction. 99.93% of
the dividends were derived from interest on municipal bonds and are not subject
to federal income taxes. To the extent a shareholder is subject to any state or
local tax laws, some or all of the dividends received may be taxable.

     The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and whether the individual would be
      deemed an "audit committee financial expert" within the meaning of
      applicable SEC rules. The Committee also considers whether the
      individual's background, skills, and experience will complement the
      background, skills, and experience of other nominees and will contribute
      to the Board. There are no differences in the manner in which the
      Committee evaluates nominees for trustees based on whether the nominee is
      recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:



      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 07/31/2007, 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.

      (3) Not applicable.
