THE FUND SUMMARY

Investment Objective

Investment Objective. The Fund seeks a high level of current interest income exempt from federal and North Carolina state income taxes for individual investors as is consistent with preservation of capital.

Fees and Expenses of the Fund

Fees and Expenses of the Fund. This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. You may qualify for sales charge discounts if you (or you and your spouse) invest, or agree to invest in the future, at least $50,000 in certain funds in the Oppenheimer family of funds. More information about these and other discounts is available from your financial professional and in the section "About Your Account" beginning on page 22 of the prospectus and in the sections "How to Buy Shares" beginning on page 79 and "Appendix A" in the Fund's Statement of Additional Information.

Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	1.01%	1.77%	1.77%

* Prior to July 1, 2009, the Manager voluntarily waived management fees and/or reimbursed Fund expenses so that "Total Annual Fund Operating Expenses," excluding interest and related expenses from inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so the waiver would also exclude interest and fees from borrowings. This undertaking may be amended or withdrawn after one year from the date of this prospectus.

Example. The following Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in a class of shares of the Fund for the time periods indicated.  The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.  Although your actual costs may be higher or lower, based on these assumptions your expenses would be as follows:

	If shares are redeemed								If shares are not redeemed
	1 Year		3 Years		5 Years		10 Years		1 Year		3 Years		5 Years		10 Years
Class A Shares	$	574	$	830	$	1,106	$	1,893	$	574	$	830	$	1,106	$	1,893
Class B Shares	$	681	$	932	$	1,310	$	1,999	$	181	$	632	$	1,110	$	1,999
Class C Shares	$	281	$	617	$	1,080	$	2,361	$	181	$	617	$	1,080	$	2,361

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23% of the average value of its portfolio.

Principal Investment Strategies

Principal Investment Strategies. The Fund invests mainly in municipal securities issued by North Carolina. Under normal market conditions, as a fundamental policy, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in securities the income from which, in the opinion of counsel to the issuer of each security, is exempt from both federal and North Carolina state income tax. These securities are generally issued by the state and its political subdivisions (such as cities, towns, counties, agencies and authorities) and primarily include municipal bonds (long-term (more than one-year) obligations), municipal notes (short-term obligations) and interests in municipal leases. They may also include securities of issuers located outside of North Carolina, such as U.S. territories, commonwealths and possessions, if the interest on such securities is not subject to federal or North Carolina state income tax. These securities are "North Carolina municipal securities" for purposes of this prospectus.

Securities whose interest is exempt from North Carolina taxes are included for purposes of the Fund's 80% requirement discussed above, even if the issuer is located outside of North Carolina. Securities that generate income subject to alternative minimum tax (AMT) will count towards the Fund's 80% requirement. The Fund selects investments without regard to this type of tax treatment.

Most of the securities the Fund buys must be "investment-grade" (rated in one of the four highest rating categories of a nationally recognized statistical rating organization, such as Standard & Poor's), although the Fund also can invest as much as 25% of its total assets in below-investment-grade securities (sometimes called "junk bonds"). The Fund may also invest in unrated securities, in which case the Fund's investment adviser, OppenheimerFunds, Inc., internally assigns ratings to those securities, after assessing their credit quality and other factors, in categories similar to those of nationally recognized rating organizations.

The Fund does not limit its investments to securities of a particular maturity range, and may hold both short- and long-term securities. However, the Fund currently focuses on longer-term securities to seek higher yields. This portfolio strategy is subject to change. 

The Fund also borrows for leverage and invests in inverse floaters, a variable rate obligation and form of derivative, to seek increased income and return. The Fund can expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters. The Fund also can borrow money to purchase additional securities, another form of "leverage". Although the amount of borrowing will vary from time to time, the amount of leveraging from borrowings will not exceed one-third of the Fund's total assets.

In selecting investments for the Fund, the portfolio managers look at a wide range of North Carolina municipal securities from different issuers that provide high current income, including unrated bonds, that have favorable credit characteristics and that provide opportunities for value. The portfolio managers may consider selling a security if any of these factors no longer applies to a security purchased for the Fund, but are not required to do so.

Principal Risks

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or from poor security selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Main Risks of Investing in Municipal Securities. Municipal securities may be subject to credit risk, credit spread risk, interest rate risk and reinvestment risk. Credit risk is the risk that the municipal issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or to repay principal, the Fund's income or share value might be reduced. A downgrade in an issuer's credit rating can reduce the market value of the issuer's securities. Credit spread risk is a risk based on the difference (or credit spread) between the market yields of two different investments of different credit quality.  When spreads widen between bonds with different quality ratings, it implies that the market is factoring more risk of default on lower-grade bonds.  A widening in credit spreads may result in a fall in the values of the Fund's securities. Interest rate risk is the risk that the value of a municipal security might fall due to a change in interest rates. When prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may sell at a lower price than their face amount or from the amount the Fund paid for them. When prevailing interest rates fall, the values of already-issued debt securities generally rise. The values of longer-term debt securities usually change more than the values of shorter-term debt securities. Reinvestment risk is the risk that when interest rates fall the Fund may be required to reinvest the proceeds from a security's sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds.

     Special Risks of Below-Investment-Grade Securities. Below-investment-grade debt securities may be subject to greater price fluctuations and have a greater risk that the issuer might not be able to pay interest and principal when due. The market for below-investment-grade securities may be less liquid and they may be harder to value or to sell at an acceptable price, especially during times of market volatility or decline.

     Because the Fund can invest up to 25% of its assets in below-investment-grade securities, the Fund's credit risks are greater than those of funds that buy only investment-grade securities.

Special Risks of North Carolina Municipal Securities. Because the Fund invests primarily in North Carolina municipal securities, the value of its portfolio investments will be highly sensitive to events affecting the financial stability of the State of North Carolina and its municipalities, agencies, authorities and other instrumentalities that issue those securities. Budgetary stress on the state or its municipalities, changes in legislation or policy, erosion of the tax base, the effects of natural disasters, or other economic, legislative or political, or social issues may have a significant negative impact on the value of state or local securities. These risks also apply to securities of issuers of U.S. territories, commonwealths or possessions, such as Puerto Rico, Guam, the Northern Mariana Islands and the Virgin Islands.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal and state income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Bond Market Volatility and Illiquidity. The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated debt securities. Under those conditions, liquidity can be reduced in response to overall economic conditions and credit tightening. It is not possible to predict when such circumstances could occur. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which the bonds are carried on the Fund's books. The Fund may need to sell large blocks of bonds to meet shareholder redemption requests or to raise cash in connection with its investments in inverse floaters. Sales of large blocks of bonds can further reduce bond prices.

Municipal Sector Concentration. While the Fund does not invest more than 25% of its total assets in a single industry, certain types of municipal securities (such as general obligation, government appropriation, municipal leases, special assessment and special tax bonds) are not considered a part of any "industry" for purposes of this policy. Therefore, the Fund may invest more than 25% of its total assets in these types of municipal securities. These types of municipal securities may finance, or pay interest from the revenues of, projects that tend to be impacted in the same way by economic, business or political developments which would increase credit risk. For example, legislation on the financing of a project or a declining economic need for the project would likely affect all similar projects.

Risks of Non-Diversification. The Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a "diversified" fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is more subject to the risks associated with and developments affecting that issuer.

Risks of Tobacco Related Bonds. In 1998, the largest U.S. tobacco manufacturers reached an out of court agreement, known as the Master Settlement Agreement (the "MSA"), to settle claims against them by 46 states and six other U.S. jurisdictions. The tobacco manufacturers agreed to make annual payments to the government entities in exchange for the release of all litigation claims. A number of the states have sold bonds that are backed by those future payments. The Fund may invest in two types of those bonds: (i) bonds that make payments only from a state's interest in the MSA and (ii) bonds that make payments from both the MSA revenue and from an "appropriation pledge" by the state. An "appropriation pledge" requires the state to pass a specific periodic appropriation to make the payments and is generally not an unconditional guarantee of payment by a state.
   The settlement payments are based on factors, including, but not limited to, annual domestic cigarette shipments, cigarette consumption, inflation and the financial capability of participating tobacco companies. Payments could be reduced if consumption decreases, if market share is lost to non-MSA manufacturers, or if there is a negative outcome in litigation regarding the MSA.
   The Fund can invest up to 25% of its total assets in tobacco-related bonds without an appropriation pledge that makes payments only from a state's interest in the MSA.

Risks of Land-Secured or "Dirt" Bonds. These special assessment or special tax bonds are issued to promote residential, commercial or industrial growth and redevelopment. They are exposed to real estate development-related risks. The bonds could default if the developments failed to progress as anticipated or if taxpayers failed to pay the assessments, fees and taxes specified in the financing plans for a project.

Borrowing and Leverage. The Fund can borrow up to one-third of the Fund's assets (including the amount borrowed) from banks. It can use those borrowings for a number of purposes, including for purchasing securities. That is referred to as "leverage." In that case, changes in the value of the Fund's investments will have a larger effect on its share price than if it did not borrow. Borrowing results in interest payments to the lenders and related expenses. The costs of borrowing for investment purposes might reduce the Fund's return if the yield on the securities purchased is less than the borrowing costs. The Fund may also borrow to meet redemption obligations, for temporary and emergency purposes, or to unwind or contribute to trusts in connection with the Fund's investment in inverse floaters.  The Fund currently participates in a line of credit with other Oppenheimer funds for its borrowing.

Risks of Derivatives. A "derivative" is an investment whose value depends on (or is derived from) the value of an underlying security, asset, interest rate, index or currency. Derivatives may be volatile and involve significant risks. Derivative transactions may require the payment of premiums and can increase portfolio turnover. Certain derivative investments may be illiquid. The underlying security or other reference on which a derivative is based, or the derivative itself, may not perform the way the Fund expects it to. The Fund could realize little or no income or lose principal from a derivative investment or a hedge might be unsuccessful. The Fund may also lose money if the issuer of a derivative fails to pay the amount due.

Inverse Floaters. The Fund invests in inverse floaters because, under ordinary circumstances, they tend to benefit from higher yields and thus provide higher income than fixed rate bonds of comparable maturity and credit quality. An inverse floater is a derivative instrument, typically created by a trust established by a counterparty, that divides a municipal security into two securities: a short-term floating rate security and a long-term floating rate security which is referred to as an "inverse floater." The inverse floater pays interest at rates that move in the opposite direction of those on the short-term floating rate security. Inverse floaters produce less income when short-term interest rates rise (and may pay no income) and more income when short-term interest rates fall. Thus, if short-term interest rates rise after the issuance of the floater, any yield advantage is reduced or eliminated. Under certain circumstances a trust may be collapsed and the Fund may be required to repay the principal amount due on the short-term securities or the difference between the liquidation value of the underlying municipal bond and the principal amount due on those securities. Inverse floaters can be more volatile than conventional fixed-rate bonds. They also entail a degree of leverage and certain inverse floaters may require the Fund to provide collateral for payments on the short-term securities or to "unwind" the transaction.

Who Is The Fund Designed For? The Fund is designed for investors seeking income exempt from federal and North Carolina state personal income taxes. The Fund does not seek capital gains or growth. Because it invests in tax-exempt securities, the Fund is not appropriate for retirement plan accounts or for investors seeking capital growth. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Investment Adviser

Investment Adviser. OppenheimerFunds, Inc. is the Fund's investment adviser (the "Manager").

Portfolio Managers

Portfolio Managers. Daniel G. Loughran, Scott S. Cottier, Troy E. Willis and Mark R. DeMitry are each a Vice President of the Fund and each has been a portfolio manager of the Fund since its inception. Marcus V. Franz has been a portfolio manager of the Fund since its inception. Michael L. Camarella is a Vice President of the Fund and has been a portfolio manager of the Fund since January 2008. 

Purchase and Sale of Fund Shares

Purchase and Sale of Fund Shares. In most cases, you can buy Fund shares with a minimum initial investment of $1,000 and make additional investments with as little as $50. For certain investment plans and retirement accounts, the minimum initial investment is $500 and, for some, the minimum additional investment is $25. For certain fee based programs the minimum initial investment is $250.

Shares may be purchased through a financial intermediary or the Distributor and redeemed through a financial intermediary or the Transfer Agent on days the New York Stock Exchange is open for trading. Shareholders may purchase or redeem shares by mail, through the website at www.oppenheimerfunds.com or by calling 1-800-225-5677. Share transactions may be paid by check, by Federal Funds wire or directly from or into your bank account.

Taxes

Taxes. Dividends paid from net investment income on tax-exempt municipal securities will be excludable from gross income for federal income tax purposes. Dividends that are derived from interest paid on certain "private activity bonds" may be an item of tax preference if you are subject to the federal alternative minimum tax. The tax treatment of dividends is the same whether they are taken in cash or reinvested. Distributions may be taxable as ordinary income or as capital gains.

Payments to Broker-Dealers and Other Financial Intermediaries

Payments to Broker-Dealers and Other Financial Intermediaries. If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), the Fund, the Manager, or their related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

MORE ABOUT THE FUND

About the Fund's Investments

The allocation of the Fund's portfolio among different types of investments will vary over time and the Fund's portfolio might not always include all of the different types of investments described below. The Statement of Additional Information contains more detailed information about the Fund's investment policies and risks.

THE FUND'S PRINCIPAL INVESTMENT STRATEGIES AND RISKS. The strategies and types of investments discussed in the Fund Summary are the ones that the Fund considers to be the most important in seeking to achieve its investment objective.  Additionally, the following strategies and risks are those the Fund expects its portfolio to be subject to as a whole.

      The Manager tries to reduce risks by selecting a wide variety of municipal investments and by carefully researching securities before they are purchased. However, changes in the overall market prices of municipal securities and the income they pay can occur at any time. The yield and share prices of the Fund will change daily based on changes in interest rates and market conditions and in response to other economic events.

     Unless this prospectus or the Statement of Additional Information states that an investment percentage restriction applies on an ongoing basis, it applies only at the time the Fund makes an investment (except for borrowing and investments in illiquid securities).

MUNICIPAL SECURITIES.   Municipal securities are issued to raise money for a variety of public or private purposes, including financing state or local governments, financing specific projects or financing public facilities. These debt obligations are issued by the state governments, as well as their political subdivisions (such as cities, towns, and counties) and their agencies and authorities. The Fund buys municipal bonds and notes, tax-exempt commercial paper, certificates of participation in municipal leases and other debt obligations. Municipal securities generally are classified as general or revenue obligations. General obligations are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue obligations are bonds whose interest is payable only from the revenues derived from a particular facility or class of facilities, or a specific excise tax or other revenue source. Some revenue obligations are private activity bonds that pay interest that may be a tax preference item for investors subject to the federal alternative minimum tax. The Fund selects investments without regard to this type of tax treatment.

Additionally, there are times when an issuer will pledge its taxing power to offer additional security to a revenue bond. These securities are sometimes called "double-barreled bonds." See, for example, tobacco bonds with an appropriation pledge as discussed earlier in this prospectus.

       The Fund can buy both long-term and short-term municipal securities. Long-term securities have a maturity of more than one year. The Fund generally focuses on longer-term securities to seek higher income.

      North Carolina municipal securities are municipal securities that are not subject (in the opinion of bond counsel to the issuer at the time they are issued) to federal and state individual income tax. The term "North Carolina municipal securities" also includes debt securities of the governments of certain possessions, territories and commonwealths of the United States if the interest is not subject to state individual income tax. Some debt securities, such as zero-coupon securities, do not pay current interest. Other securities may be subject to calls by the issuer (to redeem the debt) or to prepayment prior to their stated maturity.

Tax-Exempt Commercial Paper.  Tax-exempt commercial paper is a short-term obligation with a stated maturity of usually 270 days or less. It is issued by state and local governments or their agencies to finance seasonal working capital needs or as short-term financing in anticipation of longer-term financing. While tax-exempt commercial paper is intended to be repaid from general revenues or refinanced, it frequently is backed by a letter of credit, lending arrangement, note, repurchase agreement or other credit facility agreement offered by a bank or financial institution. Because tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper, the commercial paper of a tax-exempt issuer that is unable to continue to obtain liquidity in that manner may default. There may be a limited secondary market for issues of tax-exempt commercial paper.

Municipal Lease Obligations. Municipal leases are used by state and local governments to obtain funds to acquire land, equipment or facilities. The Fund can invest in certificates of participation that represent a proportionate interest in payments made under municipal lease obligations. Most municipal leases, while secured by the leased property, are not general obligations of the issuing municipality. They often contain "non-appropriation" clauses under which the municipal government has no obligation to make lease or installment payments in future years unless money is appropriated on a yearly basis.

If the municipal government stops making payments or transfers its payment obligations to a private entity, the obligation could lose value or become taxable. Although the obligation may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to recover the original investment. Some lease obligations may not have an active trading market, making it difficult for the Fund to sell them quickly at an acceptable price.

Municipal Sector Concentration. While the Fund's fundamental policies do not allow it to concentrate its investments (that is, to invest more than 25% of its total assets) in a single industry, certain types of municipal securities are not considered a part of any "industry" under that policy.  Examples of these types of municipal securities include:  general obligation, government appropriation, municipal leases, special assessment and special tax bonds.  Therefore, the Fund may invest more than 25% of its total assets in these types of municipal securities, which may finance similar types of projects or from which the interest is paid from revenues of similar types of projects.  "Similar types of projects" are projects that are related in such a way that economic, business or political developments tend to have the same impact on each similar project.  For example, a change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining economic need for the project, would likely affect all similar projects, thereby increasing market risk.  Thus, market or economic changes that affect a security issued in connection with one project also would affect securities issued in connection with similar types of projects. 

Although these types of municipal securities may be related to certain industries, because they are issued by governments or their political subdivisions, these types of municipal securities are not considered a part of any industry for purposes of the Fund's industry concentration policy.

Special Tax or Special Assessment Bonds (Land-Secured or "Dirt" Bonds). The Fund can invest more than 25% of its total assets in municipal securities for similar types of projects that are issued in connection with special taxing districts that are organized to plan and finance infrastructure development to induce residential, commercial and industrial growth and redevelopment. The bonds financed by these methods, such as tax assessment, special tax or tax increment financing generally are payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. These projects often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings generally are limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the projects.

Ratings of Municipal Securities the Fund Buys. The Manager may rely to some extent on credit ratings by nationally recognized statistical rating organizations in evaluating the credit risk of securities selected for the Fund's portfolio.  Credit ratings evaluate the expectation that scheduled interest and principal payments will be made in a timely manner. They do not reflect any judgment of market risk.

Rating agencies might not always change their credit rating of an issuer in a timely manner to reflect events that could affect the issuer's ability to make timely payments on its obligations. In selecting securities for its portfolio and evaluating their income potential and credit risk, the Fund does not rely solely on ratings by rating organizations but evaluates business, economic and other factors affecting issuers as well. Many factors affect an issuer's ability to make timely payments, and the credit risk of a particular security may change over time. The Manager also may use its own research and analysis. If a bond is insured, it will usually be rated by the rating agencies based on the financial strength of the insurer. The rating categories are described in an Appendix to the Statement of Additional Information. 

     Unrated Securities. Because the Fund may purchase securities that are not rated by any nationally recognized statistical rating organization, the Manager may internally assign ratings to those securities, after assessing their credit quality and other factors, in categories similar to those of nationally recognized statistical rating organizations. Unrated securities are considered "investment-grade" or "below-investment-grade" if judged by the Manager to be comparable to rated investment-grade or below-investment-grade securities. However, the Manager's rating does not constitute a guarantee of the credit quality. Some unrated securities may not have an active trading market, which means that the Fund might have difficulty selling them promptly at an acceptable price.
In evaluating the credit quality of a particular security, whether rated or unrated, the Manager will normally take into consideration a number of factors. Among them are the financial resources of the issuer, or the underlying source of funds for debt service on a security, the issuer's sensitivity to economic conditions and trends, any operating history of the facility financed by the obligation and the degree of community support for it, the capabilities of the issuer's management and regulatory factors affecting the issuer and particular facility.
A reduction in the rating of a security after the Fund buys it will not automatically require the Fund to dispose of the security. However, the Manager will evaluate such downgraded securities to determine whether to keep them in the Fund's portfolio.

The Fund can invest as much as 25% of its total assets in securities that are not "investment-grade" (measured at the time of purchase) to seek higher income.

Borrowing and Leverage.   The Fund can borrow from banks, a technique referred to as "leverage," in amounts up to one-third of the Fund's total assets (including the amount borrowed) less all liabilities and indebtedness other than borrowings. The Fund can use those borrowings for investment-related purposes such as purchasing securities believed to be desirable by the Manager when available, funding amounts necessary to unwind or "collapse" trusts that issued "inverse floaters" to the Fund (an investment vehicle used by the Fund as described in this prospectus), or to contribute to such trusts to enable them to meet tenders of their other securities by the holders. The Fund currently participates in a line of credit with other Oppenheimer funds for those purposes.  The Fund may also borrow to meet redemption obligations or for temporary and emergency purposes.  

Borrowing for leverage will subject the Fund to greater costs (for interest payments to the lender, origination fees and related expenses) than funds that do not borrow for leverage and these other purposes.  The interest on borrowed money is an expense that might reduce the Fund's yield, especially if the cost of borrowing to buy securities exceeds the yield on the securities purchased with the proceeds of a loan.  Using leverage may also make the Fund's share price more sensitive, i.e. volatile, to interest rate changes than if the Fund did not use leverage due to the tendency to exaggerate the effect of any increase or decrease in the value of the Fund's portfolio securities.  The use of leverage may also cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements under the Investment Company Act.

Special Risks of Derivative Investments. The Fund can invest in different types of "derivative" investments that are consistent with its investment strategies. A derivative is an investment whose value depends on (or is derived from) the value of an underlying security, asset, interest rate, index or currency. Inverse floaters are the primary type of derivative the Fund can use.

        The Fund may use derivatives to seek income or capital gain or to hedge against the risks of other investments. Derivatives may allow the Fund to increase or decrease its exposure to certain markets or risks very quickly. Examples include, but are not limited to, interest rate swaps or municipal bond swaps. While the Fund may use derivatives for hedging purposes, it typically does not use hedging instruments, such as options, to hedge investment risks.

Derivatives may be volatile and may involve significant risks. Derivative transactions may require the payment of premiums. Certain derivative investments held by the Fund may be illiquid, making it difficult to close out an unfavorable position. The underlying security or other reference rate on which a derivative is based, or the derivative itself, may not perform as expected. As a result, the Fund could realize little or no income or lose principal from the investment, or a hedge might be unsuccessful. The Fund may also lose money on a derivative investment if the issuer fails to pay the amount due.

Inverse Floaters.  The Fund may invest in inverse floaters to seek greater income and total return. Inverse floaters, under ordinary circumstances, tend to benefit from higher yields and thus provide higher income than fixed rate bonds of comparable maturity and credit quality. An inverse floater is a derivative instrument, typically created by a trust, that divides a municipal security into two securities: a short-term tax-exempt floating rate security (sometimes referred to as a "tender option bond") and a long-term tax-exempt floating rate security (referred to as a "residual certificate" or "inverse floater") that pays interest at rates that move in the opposite direction of the yield on the short-term floating rate security. The purchaser of a "tender option bond" has the right to tender the security periodically for repayment of the principal value. As short-term interest rates rise, inverse floaters produce less current income (and, in extreme cases, may pay no income) and as short-term interest rates fall, inverse floaters produce more current income. Thus, if short-term interest rates rise after the issuance of the floater, any yield advantage is reduced or eliminated.

To facilitate the creation of inverse floaters, the Fund may purchase a municipal security and subsequently transfer it to a broker-dealer (the sponsor), which deposits the municipal security in a trust. The trust issues the residual certificates and short-term floating rate securities. The trust documents enable the Fund to withdraw the underlying bond to unwind or "collapse" the trust (upon tendering the residual certificate and paying the value of the short-term bonds and certain other costs). The Fund may also purchase inverse floaters created by municipal issuers directly or by other parties that have deposited municipal bonds into a sponsored trust.

The Fund's investments in inverse floaters involve certain risks. The market value of an inverse floater residual certificate can be more volatile than that of a conventional fixed-rate bond having similar credit quality, maturity and redemption provisions. Typically, inverse floater residual certificates tend to underperform fixed-rate bonds when long-term interest rates are rising but tend to outperform fixed-rate bonds when long-term interest rates are stable or falling. Inverse floater residual certificates entail a degree of leverage because the trust issues short-term securities in a ratio to the residual certificates with the underlying long-term bond providing collateral for the obligation to pay the principal value of the short-term securities if and when they are tendered. If the Fund has created the inverse floater by depositing a long-term bond into a trust, it may be required to provide additional collateral for the short-term securities if the value of the underlying bond deposited in the trust falls.

An inverse floater that has a higher degree of leverage is typically more volatile with respect to its price and income than an inverse floater having a lower degree of leverage. Under inverse floater arrangements, if the remarketing agent that offers the short-term securities for sale is unable to sell them, or if the holders tender (or put) them for repayment of principal and the remarketing agent is unable to remarket them, the remarketing agent may cause the trust to be collapsed, and in the case of floaters created by the Fund, the Fund will then be required to repay the principal amount of the tendered securities. During times of market volatility, illiquidity or uncertainty, the Fund could be required to sell other portfolio holdings at a disadvantageous time to raise cash to meet that obligation.

Some inverse floaters may have a "cap," so that if interest rates rise above the cap, the security pays additional interest income. If rates do not rise above the cap, the Fund will have paid an additional amount for that feature that has proved worthless.

The Fund may also enter into "shortfall and forbearance" agreements with respect to inverse floaters. Under those agreements, upon liquidation of the trust, the Fund is committed to pay the trust the difference between the liquidation value of the underlying municipal bond on which the inverse floater is based and the principal amount payable to the holders of the short-term floating rate security that is based on the same underlying municipal security. Although the Fund has the risk that it may be required to make such additional payment, these agreements may offer higher interest payments than a standard inverse floater.

      Accounting Treatment of Inverse Floaters.  Because of the accounting treatment for inverse floaters created by the Fund's transfer of a municipal bond to a trust, the Fund's financial statements will reflect these transactions as "secured borrowings," which affects the Fund's expense ratios, statements of income and assets and liabilities and causes the Fund's Statement of Investments to include the underlying municipal bond. The Fund's annual fund operating expenses, shown earlier in this prospectus, include certain expenses and fees related to the Fund's investments in inverse floaters. Some of those expenses are liabilities with respect to interest paid on short-term floating rate notes issued by the trusts whose inverse floater certificates are held by the Fund. Under accounting rules, the Fund also recognizes additional income in an amount that directly corresponds to these expenses and, as a result the Fund's net asset values per share and total returns have not been affected by these additional expenses.

Floating Rate/Variable Rate Obligations. Some municipal securities have variable or floating interest rates. Variable rates are adjustable at stated periodic intervals. Floating rates are automatically adjusted according to a specified market rate for those investments, such as, for example, the percentage of LIBOR, the SIFMA Municipal Swap Index or the percentage of the prime rate of a bank. These obligations may be secured by bank letters of credit or other credit support arrangements. Inverse floaters, discussed in this prospectus, are a type of variable rate obligation.

When-Issued and Delayed-Delivery Transactions. The Fund may purchase municipal securities on a "when-issued" basis and may purchase or sell such securities on a "delayed-delivery" basis. "When-issued" or "delayed-delivery" refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. Between the purchase and settlement date, no payment is made for the security and no interest accrues to the buyer from the investment. There is a risk of loss to the Fund if the value of the security declines prior to the settlement date.

The securities are subject to changes in value from market fluctuations during the period until settlement and the value of the security on the delivery date may be more or less than the Fund paid. The Fund may lose money if the value of the security declines below the purchase price.

OTHER INVESTMENT STRATEGIES AND RISKS. The Fund can also use the investment techniques and strategies described below. The Fund might not use all of these techniques or strategies or might only use them from time to time.

Percentage of LIBOR Notes (PLNs). The Fund may invest in Percentage of LIBOR Notes ("PLNs") which are variable rate municipal securities based on the London Interbank Offered Rate ("LIBOR"), a widely used benchmark for short-term interest rates and used by banks for interbank loans with other banks. A PLN typically pays interest based on a percentage of a LIBOR rate for a specified time plus an established yield premium. Due to their variable rate features, PLNs will generally pay higher levels of income in a rising short-term interest rate environment and lower levels of income as short-term interest rates decline. In times of substantial market volatility, however, PLNs may not perform as anticipated. The value of a PLN also may decline due to other factors, such as changes in credit quality of the underlying bond.

Because the market for PLNs is relatively new and still developing, the Fund's ability to engage in transactions using such instruments may be limited. There is no assurance that a liquid secondary market will exist for any particular PLN or at any particular time, and so the Fund may not be able to close a position in a PLN when it is advantageous to do so. The Fund may also transfer a PLN to a sponsor to create an inverse floater, which may further increase the volatility of the market value of a PLN or the inverse floater.

Zero-Coupon Securities. The Fund can invest without limit in zero-coupon securities.  These debt obligations do not pay interest prior to their maturity date or else they do not start to pay interest at a stated coupon rate until a future date. They are issued and traded at a discount from their face amount. The discount varies as the securities approach their maturity date (or the date interest payments are scheduled to begin). When interest rates change, zero-coupon securities are subject to greater fluctuations in their value than securities that pay current interest. The Fund accrues the discount on zero-coupon bonds as tax-free income on a current basis. The Fund may have to pay out the imputed income on zero-coupon securities without receiving actual cash payments currently.

Illiquid Securities. Investments may be illiquid because they do not have an active trading market, making it difficult to value them or dispose of them promptly at an acceptable price. The Manager monitors holdings of illiquid securities on an ongoing basis to determine whether to sell any holdings.

        The Fund will not invest more than 15% of its net assets in illiquid securities.

Taxable Investments. The Fund can invest up to 20% of its net assets (plus borrowings for investment purposes) in investments that generate income subject to income taxes. Taxable investments include, for example, hedging instruments, repurchase agreements, and many of the types of securities the Fund would buy for temporary defensive purposes. The Fund does not anticipate investing substantial amounts of its assets in taxable investments under normal market conditions or as part of its normal trading strategies and policies. 

Temporary Defensive and Interim Investments. For temporary defensive purposes in times of adverse or unstable market, economic or political conditions, the Fund can invest up to 100% of its assets in investments that may be inconsistent with the Fund's principal investment strategies. Generally, the Fund would invest in short-term municipal securities, but could also invest in U.S. Government securities or highly-rated corporate debt securities. The Fund might also hold these types of securities as interim investments pending the investment of proceeds from the sale of Fund shares or the sale of Fund portfolio securities or to meet anticipated redemptions of Fund shares. The income from some temporary defensive investments may not be tax-exempt, and therefore to the extent the Fund invests in these securities, it might not achieve its investment objective.

Portfolio Turnover. A change in the securities held by the Fund is known as "portfolio turnover." The Fund may engage in active and frequent trading to try to achieve its investment objective and may have a portfolio turnover rate of over 100% annually. Increased portfolio turnover may result in higher brokerage fees or other transaction costs, which can reduce performance. However, the Fund ordinarily incurs little or no brokerage expense because most of the Fund's portfolio transactions are principal trades that do not require payment of brokerage commission. If the Fund realizes capital gains when it sells investments, it generally must pay those gains to shareholders, increasing its taxable distributions. The Financial Highlights table at the end of this prospectus shows the Fund's portfolio turnover rates during past fiscal years.

Conflicts of Interest. The investment activities of the Manager and its affiliates in regard to other funds and accounts they manage may present conflicts of interest that could disadvantage the Fund and its shareholders. The Manager or its affiliates may provide investment advisory services to other funds and accounts that have investment objectives or strategies that differ from, or are contrary to, those of the Fund. That may result in another fund or account holding investment positions that are adverse to the Fund's investment strategies or activities. Other funds or accounts advised by the Manager or its affiliates may have conflicting interests arising from investment objectives that are similar to those of the Fund. Those funds and accounts may engage in, and compete for, the same types of securities or other investments as the Fund or invest in securities of the same issuers that have different, and possibly conflicting, characteristics. The trading and other investment activities of those other funds or accounts may be carried out without regard to the investment activities of the Fund and, as a result, the value of securities held by the Fund or the Fund's investment strategies may be adversely affected. The Fund's investment performance will usually differ from the performance of other accounts advised by the Manager or its affiliates and the Fund may experience losses during periods in which other accounts advised by the Manager or its affiliates achieve gains. The Manager has adopted policies and procedures designed to address potential conflicts of interest identified by the Manager; however, such policies and procedures may also limit the Fund's investment activities and affect its performance.

CHANGES TO THE FUND'S INVESTMENT POLICIES. The Fund's fundamental investment policies cannot be changed without the approval of a majority of the Fund's outstanding voting shares; however, the Fund's Board can change non-fundamental policies without a shareholder vote. Significant policy changes will be described in supplements to this prospectus. The Fund's investment objective is a fundamental policy. Other investment restrictions that are fundamental policies are listed in the Fund's Statement of Additional Information. An investment policy is not fundamental unless this prospectus or the Statement of Additional Information states that it is.

PORTFOLIO HOLDINGS

The Fund's portfolio holdings are included in its semi-annual and annual reports that are distributed to its shareholders within 60 days after the close of the applicable reporting period. The Fund also discloses its portfolio holdings in its Statements of Investments on Form N-Q, which are public filings that are required to be made with the Securities and Exchange Commission within 60 days after the end of the Fund's first and third fiscal quarters. Therefore, the Fund's portfolio holdings are made publicly available no later than 60 days after the end of each of its fiscal quarters. 

A description of the Fund's policies and procedures with respect to the disclosure of its portfolio holdings is available in the Fund's Statement of Additional Information.

How the Fund is Managed

THE MANAGER. OppenheimerFunds, Inc., the Manager, chooses the Fund's investments and handles its day-to-day business. The Manager carries out its duties, subject to the policies established by the Fund's Board of Trustees, under an investment advisory agreement that states the Manager's responsibilities. The agreement sets the fees the Fund pays to the Manager and describes the expenses that the Fund is responsible to pay to conduct its business.

The Manager has been an investment adviser since 1960. The Manager managed funds with approximately 6 million shareholder accounts as of June 30, 2010. The Manager is located at Two World Financial Center, 225 Liberty Street, 11th Floor, New York, New York 10281-1008.

Advisory Fees.  Under the Fund's investment advisory agreement, the Fund pays the Manager an advisory fee, calculated on the daily net assets of the Fund, at an annual rate that declines on additional assets as the Fund's assets grow: 0.55% of the first $500 million of average annual net assets, 0.50% of the next $500 million, 0.45% of the next $500 million and 0.40% of average annual net assets over $1.5 billion. The Fund's management fee for its last fiscal year ended March 31, 2010 was 0.55% of average annual net assets for each class of shares.

Prior to July 1, 2009, the Manager voluntarily waived management fees and/or reimbursed the Fund for certain expenses so that the "Total Annual Fund Operating Expenses", excluding expenses attributable to the Fund's investment in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that the Fund's "Total Annual Fund Operating Expenses," excluding expenses attributable to the Fund's investments in inverse floaters and interest and fees from borrowings, will not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for Class B and Class C shares. This undertaking may be amended or withdrawn after one year from the date of this prospectus.

The Fund's transfer agent has voluntarily agreed to limit its fees to 0.35% of average annual net assets per fiscal year for all classes. This undertaking may be amended or withdrawn at any time. For the Fund's fiscal year ended March 31, 2010, the transfer agent's fees did not exceed this expense limitation. Actual total annual fund operating expenses for the fiscal year ended March 31, 2010 were those shown in the Annual Fund Operating Expenses table earlier in this prospectus. The Fund's management fee and other annual operating expenses may vary in future years.

     A discussion regarding the basis for the Board of Trustees' approval of the investment advisory contract for the Fund is available in the Fund's Semi-Annual Report to shareholders for the period ended September 30, 2009.

MORE ABOUT YOUR ACCOUNT

About Your Account

Where Can You Buy Fund Shares? Oppenheimer funds may be purchased either directly or through a variety of "financial intermediaries" that offer Fund shares to their clients. Financial intermediaries include securities dealers, financial advisers, brokers, banks, trust companies, insurance companies and the sponsors of fund "supermarkets," fee-based advisory or wrap fee programs.

WHAT CLASSES OF SHARES DOES THE FUND OFFER? The Fund offers investors three different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different expenses and will usually have different share prices. When you buy shares, be sure to specify the class of shares you wish to purchase. If you do not choose a class, your investment will be made in Class A shares.

Class A Shares. If you buy Class A shares, you will pay an initial sales charge on investments up to $1 million for regular accounts or lesser amounts if you qualify for certain fee waivers. The amount of the sales charge will vary depending on the amount you invest. The sales charge rates for different investment amounts are listed in "About Class A Shares" below.

Class B Shares. If you buy Class B shares, you will pay no sales charge at the time of purchase, but you will pay an annual asset-based sales charge (distribution fee) over a period of approximately six years. If you sell your shares within six years after buying them, you will normally pay a contingent deferred sales charge. The amount of the contingent deferred sales charge varies depending on how long you own your shares, as described in "About Class B Shares" below.

Class C Shares. If you buy Class C shares, you will pay no sales charge at the time of purchase, but you will pay an ongoing asset-based sales charge. If you sell your shares within 12 months after buying them, you will normally pay a contingent deferred sales charge of 1.0%, as described in "About Class C Shares" below.

Certain sales charge waivers may apply to purchases or redemptions of Class A, Class B, or Class C shares. More information about those waivers is available in the Fund's Statement of Additional Information, or by clicking on the hyperlink "Sales Charge Waivers" under the heading "Fund Information" on the OppenheimerFunds website at "www.oppenheimerfunds.com."

WHAT IS THE MINIMUM INVESTMENT? In most cases, you can buy Fund shares with a minimum initial investment of $1,000 and make additional investments with as little as $50. The minimum additional investment requirement does not apply to reinvested dividends from the Fund or from other Oppenheimer funds or to omnibus account purchases. A $25 minimum applies to additional investments through an Asset Builder Plan, an Automatic Exchange Plan or a government allotment plan established before November 1, 2002. Reduced initial minimums are available in certain circumstances, including under the following investment plans: 

• For an Asset Builder Plan or Automatic Exchange Plan or a government allotment plan, the minimum initial investment is $500.

• For certain fee based programs that have an agreement with the Distributor, a minimum initial investment of $250 applies.

• The minimum purchase amounts listed do not apply to omnibus accounts.

Minimum Account Balance. A $12 annual "minimum balance fee" is assessed on Fund accounts with a value of less than $500. The fee is automatically deducted from each applicable Fund account annually in September. See the Statement of Additional Information for information about the circumstances under which this fee will not be assessed. Small accounts may be involuntarily redeemed by the Fund if the value has fallen below $500 for reasons other than a decline in the market value of the shares.

Choosing a Share Class

CHOOSING A SHARE CLASS. Once you decide that the Fund is an appropriate investment for you, the decision as to which class of shares is best suited to your needs depends on a number of factors that you should discuss with your financial adviser. The Fund's operating costs that apply to a share class and the effect of the different types of sales charges on your investment will affect your investment results over time. For example, the net asset value and the dividends of Class B and Class C shares will be reduced by additional expenses borne by those classes such as the asset-based sales charge.

     Two of the factors to consider are how much you plan to invest and, while future financial needs cannot be predicted with certainty, how long you plan to hold your investment. For example, with larger purchases that qualify for a reduced initial sales charge on Class A shares, the effect of paying an initial sales charge on purchases of Class A shares may be less over time than the effect of the asset-based sales charges on Class B or Class C shares. If your goals and objectives change over time and you plan to purchase additional shares, you should re-evaluate each of the factors to see if you should consider a different class of shares.

      The discussion below is not intended to be investment advice or a recommendation, because each investor's financial considerations are different. The discussion below assumes that you will purchase only one class of shares and not a combination of shares of different classes. These examples are based on approximations of the effects of current sales charges and expenses projected over time, and do not detail all of the considerations in selecting a class of shares. You should analyze your options carefully with your financial adviser before making that choice.

• Investing for the Shorter Term. While the Fund is meant to be a long-term investment, if you have a relatively short-term investment horizon (that is, if you do not plan to hold your shares for six years or more), you should consider investing in Class C shares. That is because of the effect of the initial sales charge on Class A shares or the Class B contingent deferred sales charge if you redeem within six years.

• Investing for the Longer Term. If you are investing less than $100,000 for the longer term and do not expect to need access to your money for six years or more, Class B shares may be appropriate.

• Amount of Your Investment. Your choice will also depend on how much you plan to invest. For shorter-term investments of less than $100,000, Class C shares might be the appropriate choice because there is no initial sales charge on Class C shares, and the contingent deferred sales charge does not apply to shares you redeem after holding them for one year or more. However, if you plan to invest more than $100,000, and as your investment horizon increases toward six years, Class C shares might not be as advantageous as Class A shares. That is because over time the ongoing asset-based sales charge on Class C shares will have a greater impact on your account than the reduced front-end sales charge available for Class A share purchases of $100,000 or more. If you invest $1 million or more, in most cases Class A shares will be the most advantageous choice, no matter how long you intend to hold your shares.

     The Distributor normally will not accept purchase orders from a single investor for more than $100,000 of Class B shares or for $1 million or more of Class C shares. Dealers or other financial intermediaries are responsible for determining the suitability of a particular share class for an investor.

Are There Differences in Account Features That Matter to You? Some account features may not be available for all share classes. Other features may not be advisable because of the effect of the contingent deferred sales charge. Therefore, you should carefully review how you plan to use your investment account before deciding which class of shares to buy.

How Do Share Classes Affect Payments to Your Financial Intermediary? The Class B and Class C contingent deferred sales charges and asset-based sales charges have the same purpose as the front-end sales charge or contingent deferred sales charge on Class A shares: to compensate the Distributor for concessions and expenses it pays to brokers, dealers and other financial intermediaries for selling Fund shares. Those financial intermediaries may receive different compensation for selling different classes of shares. The Manager or Distributor may also pay dealers or other financial intermediaries additional amounts from their own resources based on the value of Fund shares held by the intermediary for its own account or held for its customers accounts. For more information about those payments, see "Payments to Financial Intermediaries and Service Providers" below.

ABOUT CLASS A SHARES. Class A shares are sold at their offering price, which is the net asset value of the shares (described below) plus, in most cases, an initial sales charge. The Fund receives the amount of your investment, minus the sales charge, to invest for your account. In some cases, Class A purchases may qualify for a reduced sales charge or a sales charge waiver, as described below and in the Statement of Additional Information.

The Class A sales charge rate varies depending on the amount of your purchase. A portion or all of the sales charge may be retained by the Distributor or paid to your broker, dealer or other financial intermediary as a concession. The current sales charge rates and concessions paid are shown in the table below. There is no initial sales charge on Class A purchases of $1 million or more, but a contingent deferred sales charge (described below) may apply.

Amount of Purchase	Front-End Sales Charge As a Percentage of Offering Price	Front-End Sales Charge As a Percentage of Net Amount Invested	Concession As a Percentage of Offering Price
Less than $50,000	4.75%	4.98%	4.00%
$50,000 or more but less than $100,000	4.50%	4.71%	4.00%
$100,000 or more but less than $250,000	3.50%	3.63%	3.00%
$250,000 or more but less than $500,000	2.50%	2.56%	2.25%
$500,000 or more but less than $1 million	2.00%	2.04%	1.80%

Due to rounding, the actual sales charge for a particular transaction may be higher or lower than the rates listed above.

Reduced Class A Sales Charges. Under a "Right of Accumulation" or a "Letter of Intent" you may be eligible to buy Class A shares of the Fund at the reduced sales charge rates that would apply to a larger purchase. The Fund reserves the right to modify or to cease offering these programs at any time.

• Right of Accumulation. To qualify for the reduced Class A sales charge that would apply to a larger purchase than you are currently making, you can add the value of shares that you and your spouse currently own, and other purchases that you are currently making, to the value of your Class A share purchase of the Fund. You may count Class A, Class B and Class C shares of the Fund and other Oppenheimer funds and Class A, Class B, Class C, Class G and Class H units in adviser sold Section 529 plans, for which the Manager or the Distributor serves as the "Program Manager" or "Program Distributor." The Distributor or the financial intermediary through which you are buying shares will determine the value of the shares you currently own based on the greater of their current offering price or the amount you paid for the shares. For purposes of calculating that value, the Distributor will only take into consideration the value of shares owned as of December 31, 2007 and any shares purchased subsequently. The value of any shares that you have redeemed and the value of Class A shares of Oppenheimer Money Market Fund, Inc. or Oppenheimer Cash Reserves on which you have not paid a sales charge will not be counted for this purpose.

In totaling your holdings, you may count shares held in:

• your individual accounts (including IRAs, 403(b) plans and eligible 529 plans),

• your joint accounts with your spouse,

• accounts you or your spouse hold as trustees or custodians on behalf of your children who are minors.

     A fiduciary can apply rights of accumulation to all shares purchased for a trust, estate or other fiduciary account that has multiple accounts (including employee benefit plans for the same employer and Single K plans for the benefit of a sole proprietor). 

     If you are buying shares directly from the Fund, you must inform the Distributor of your eligibility and holdings at the time of your purchase in order to qualify for the Right of Accumulation. If you are buying shares through a financial intermediary you must notify the intermediary of your eligibility for the Right of Accumulation at the time of your purchase.

     To count eligible shares held in accounts at other firms, you may be requested to provide the Distributor or your current financial intermediary with a copy of account statements showing your current holdings of the Fund, other eligible Oppenheimer funds or qualifying 529 plans. Shares purchased under a Letter of Intent may also qualify as eligible holdings under a Right of Accumulation.

• Letter of Intent. You may also qualify for reduced Class A sales charges by submitting a Letter of Intent to the Distributor. A Letter of Intent is a written statement of your intention to purchase a specified value of Class A, Class B or Class C shares of the Fund or other Oppenheimer funds or Class A, Class B, Class C, Class G or Class H unit purchases in adviser sold Section 529 plans, for which the Manager or Distributor serves as the Program Manager or Program Distributor, over a 13-month period. The total amount of your intended purchases will determine the reduced sales charge rate that will apply to your Class A share purchases during that period. You must notify the Distributor or your financial intermediary of any qualifying 529 plan purchases or purchases through other financial intermediaries.

     Purchases of Class N or Class Y shares, purchases made by reinvestment of dividends or capital gains distributions from other Oppenheimer funds, purchases of Class A shares with redemption proceeds under the "reinvestment privilege" described below, and purchases of Class A shares of Oppenheimer Money Market Fund, Inc. or Oppenheimer Cash Reserves on which a sales charge has not been paid do not count as "qualified shares" for satisfying the terms of a Letter.

     Submitting a Letter of Intent does not obligate you to purchase the specified amount of shares. If you do not complete the anticipated purchases, you will be charged the difference between the sales charge that you paid and the sales charge that would apply to the actual value of shares you purchased. A certain portion of your shares will be held in escrow by the Fund's Transfer Agent for this purpose. Please refer to "How to Buy Shares – Letters of Intent" in the Fund's Statement of Additional Information for more complete information. You may also be able to apply the Right of Accumulation to purchases you make under a Letter of Intent.

Class A Contingent Deferred Sales Charge. There is no initial sales charge on Class A share purchases totaling $1 million or more of one or more of the Oppenheimer funds. However, those Class A shares may be subject to a 0.75% contingent deferred sales charge if they are redeemed within an 18-month "holding period" measured from the beginning of the calendar month in which they were purchased (except for shares in certain retirement plans). That sales charge will be calculated on the lesser of the original net asset value of the redeemed shares or the aggregate net asset value of the redeemed shares at the time of redemption.

The Class A contingent deferred sales charge does not apply to shares purchased by the reinvestment of dividends or capital gain distributions and will not exceed the aggregate amount of the concessions the Distributor pays on all of your purchases of Class A shares, of all Oppenheimer funds, that are subject to the contingent deferred sales charge.

The Distributor pays concessions from its own resources on certain purchases of Class A shares of one or more of the Oppenheimer funds that, in the aggregate, total $1 million or more. If purchases of a Fund's Class A shares are included in any such purchase, the Distributor will pay the concession on those Fund shares at the rate of 0.75% of their net asset value. A concession will not be paid on shares purchased by exchange or shares that were previously subject to a front-end sales charge and dealer concession.

ABOUT CLASS B SHARES. Class B shares are sold at net asset value per share without an initial sales charge. However, if Class B shares are redeemed within six years from the beginning of the calendar month in which they were purchased, a contingent deferred sales charge will be deducted from the redemption proceeds. Class B shares are also subject to an asset-based sales charge that is calculated daily based on an annual rate of 0.75%. The Class B contingent deferred sales charge and asset-based sales charge are paid to compensate the Distributor for providing distribution-related services to the Fund in connection with the sale of Class B shares.

The amount of the Class B contingent deferred sales charge will depend on the number of years since you invested, according to the following schedule:

Years since Beginning of Month in Which Purchase Order was Accepted	Contingent Deferred Sales Charge on Redemptions in That Year (As % of Amount Subject to Charge)
0-1	5.0%
1-2	4.0%
2-3	3.0%
3-4	3.0%
4-5	2.0%
5-6	1.0%
More than 6	None

In the table, a "year" is a 12-month period. In applying the contingent deferred sales charge, all purchases are considered to have been made on the first regular business day of the month in which the purchase was made.

Automatic Conversion of Class B Shares. Class B shares automatically convert to Class A shares six years (72 months) after you purchase them. This conversion eliminates the Class B asset-based sales charge, however, the shares will be subject to the ongoing Class A fees and expenses. The conversion is based on the relative net asset value of the two classes, and no sales load or other charge is imposed. When any Class B shares that you hold convert to Class A shares, all other Class B shares that were acquired by reinvesting dividends and distributions on the converted shares will also convert. For further information on the conversion feature and its tax implications, see "Class B Conversion" in the Statement of Additional Information.

ABOUT CLASS C SHARES. Class C shares are sold at net asset value per share without an initial sales charge. However, if Class C shares are redeemed within a 12 month "holding period" from the beginning of the calendar month in which they were purchased, a contingent deferred sales charge of 1.00% may be deducted from the redemption proceeds. Class C shares are also subject to an asset-based sales charge that is calculated daily based on an annual rate of 0.75%. The Class C contingent deferred sales charge and asset-based sales charge are paid to compensate the Distributor for providing distribution-related services to the Fund in connection with the sale of Class C shares.

The Price of Fund Shares

Shares may be purchased at their offering price which is the net asset value per share plus any initial sales charge that applies. Shares are redeemed at their net asset value per share less any contingent deferred sales charge that applies. The net asset value that applies to a purchase or redemption order is the next one calculated after the Distributor receives the order, in proper form as described in this prospectus, or after any agent appointed by the Distributor receives the order in proper form as described in this prospectus. Your financial intermediary can provide you with more information regarding the time you must submit your purchase order and whether the intermediary is an authorized agent for the receipt of purchase and redemption orders.

Net Asset Value. The Fund calculates the net asset value of each class of shares as of the close of the New York Stock Exchange (NYSE), on each day the NYSE is open for trading (referred to in this prospectus as a "regular business day"). The NYSE normally closes at 4:00 p.m., Eastern time, but may close earlier on some days. All references to time in this prospectus are to "Eastern time."

The net asset value per share for a class of shares on a "regular business day" is determined by dividing the value of the Fund's net assets attributable to that class by the number of shares of that class outstanding on that day. The Fund's assets generally trade in the over-the-counter market rather than on a securities exchange. Therefore, to determine net asset values, the Fund assets are generally valued at the mean between the bid and asked prices as determined by a pricing service. If the prices determined by the pricing service do not accurately reflect fair value for a security (in the Manager's judgment) or if a security's value has been materially affected by events occurring after the price is received from the pricing service and before the time as of which the Fund's net asset values are calculated that day, that security may be valued by another method that the Board of Trustees believes accurately reflects the fair value.

The Board has adopted valuation procedures for the Fund and has delegated the day-to-day responsibility for fair value determinations to the Manager's Valuation Committee. Fair value determinations by the Manager are subject to review, approval and ratification by the Board at its next scheduled meeting after the fair valuations are determined. In determining whether prices received from the pricing services are reliable, the Manager monitors the information it receives in the ordinary course of its investment management responsibilities for significant events that it believes in good faith will affect the prices of the securities of issuers held by the Fund. Those may include events affecting specific issuers or events affecting securities markets (for example, a securities market closes early because of a natural disaster). The Fund uses fair value pricing procedures to reflect what the Manager and the Board believe to be more accurate values for the Fund's portfolio securities, although it may not always be able to accurately determine such values. There can be no assurance that the Fund could obtain the fair value assigned to a security if it were to sell the security at the same time at which the Fund determines its net asset value per share.

Contingent Deferred Sales Charge. If you redeem shares during their applicable contingent deferred sales charge holding period, the contingent deferred sales charge generally will be deducted from the redemption proceeds. In some circumstances you may be eligible for one of the waivers described in "Sales Charge Waivers" below and in the "Special Sales Charge Arrangements and Waivers" Appendix to the Statement of Additional Information. You must advise the Transfer Agent or your financial intermediary of your eligibility for a waiver when you place your redemption request.

       A contingent deferred sales charge will be based on the net asset value of the redeemed shares at the time of redemption or the original net asset value, whichever is lower. A contingent deferred sales charge is not imposed on:

• any increase in net asset value over the initial purchase price,

• shares purchased by the reinvestment of dividends or capital gains distributions, or

• shares eligible for a sales charge waiver (see "Sales Charge Waivers" below).

The Fund redeems shares in the following order:

• shares acquired by the reinvestment of dividends or capital gains distributions,

• other shares that are not subject to the contingent deferred sales charge, and

• shares held the longest during the holding period.

     You are not charged a contingent deferred sales charge when you exchange shares of the Fund for shares of other Oppenheimer funds. However, if you exchange your shares within the applicable holding period, your original holding period will carry over to the shares you acquire, even if the new fund has a different holding period.

SALES CHARGE WAIVERS. The Fund and the Distributor offer the following opportunities to purchase shares without front-end or contingent deferred sales charges. The Fund reserves the right to amend or discontinue these programs at any time without prior notice.

• Dividend Reinvestment. Dividends or capital gains distributions may be reinvested in shares of the Fund, or any of the other Oppenheimer funds into which shares of the Fund may be exchanged, without a sales charge.

• Exchanges of Shares. There is no sales charge on exchanges of shares except for exchanges of Class A shares of Oppenheimer Money Market Fund, Inc. or Oppenheimer Cash Reserves on which you have not paid a sales charge.

• Reinvestment Privilege. There is no sales charge on reinvesting the proceeds from redemptions of Class A shares or Class B shares that occurred within the previous six months if you paid an initial or contingent deferred sales charge on the redeemed shares. This reinvestment privilege does not apply to reinvestment purchases made through automatic investment options. You must advise the Distributor, the Transfer Agent or your financial intermediary that you qualify for the waiver at the time you submit your purchase order.

     In addition, the "Special Sales Charge Arrangements and Waivers" Appendix to the Statement of Additional Information provides detailed information about certain other initial sales charge and contingent deferred sales charge waivers and arrangements. A description of those sales charge waivers and arrangements is available for viewing on the OppenheimerFunds website at www.oppenheimerfunds.com (follow the hyperlink "Sales Charges & Breakpoints," under the heading "Fund Information") and may also be ordered by calling 1-800-225-5677. You must advise the Distributor, the Transfer Agent or your financial intermediary that you qualify for one of those waivers at the time you submit your purchase order or redemption request.

How to Buy, Sell and Exchange Shares

BUYING SHARES. You can buy shares in several ways. The Distributor has appointed certain financial intermediaries, including brokers, dealers and others, as servicing agents to accept purchase and redemption orders. The Distributor or servicing agent must receive your order, in proper form, by the close of the NYSE for you to receive that day's offering price. If your order is received on a day when the NYSE is closed or after it has closed, the order will receive the next offering price that is determined. To be in proper form, your purchase order must comply with the procedures described below. The Distributor, in its sole discretion, may reject any purchase order for the Fund's shares.

Buying Shares Through a Financial Intermediary. You can buy shares through any servicing agent (a broker, dealer, or other financial intermediary) that has a sales agreement with the Distributor. Your servicing agent will place your order with the Distributor on your behalf. A servicing agent may charge a processing fee for that service. Your account information will be shared with the financial intermediary designated as the dealer of record for the account.

Buying Shares Through the Distributor. We recommend that you discuss your investment with a financial adviser before you make a purchase to be sure that the Fund is appropriate for you. If you want to purchase shares directly from the Distributor, complete an OppenheimerFunds new account application and mail it with a check payable in U.S. dollars to "OppenheimerFunds Distributor, Inc." to the address on the back cover. If you do not list a dealer on your application, the Distributor is designated as the broker-dealer of record, but solely for the purpose of acting as your agent to purchase the shares and Class A shares are your only purchase option. Class B or Class C shares may not be purchased by a new investor directly from the Distributor without the investor designating another registered broker-dealer. However, if a current investor no longer has a broker-dealer of record for an existing Class B or Class C account, the Distributor is automatically designated as the broker-dealer of record, but solely for the purpose of acting as your agent to purchase the shares. If you submit a purchase request to the Distributor without designating the fund you wish to invest in, your investment will be made in Class A shares of Oppenheimer Money Market Fund, Inc. This policy does not apply to purchases by or for certain retirement plans or accounts. For more information regarding undesignated investments, please call the Transfer Agent at the number on the back cover of this prospectus.

• Involuntary Redemptions. In some circumstances, involuntary redemptions may be made to repay the Distributor for losses from the cancellation of share purchase orders.

Identification Requirements. Federal regulations may require the Fund to obtain your name, your date of birth (for a natural person), your residential street address or principal place of business, and your Social Security Number, Employer Identification Number or other government-issued identification when you open an account. Additional information may be required to open a corporate account or in certain other circumstances. The Fund or the Transfer Agent may use this information to verify your identity. The Fund may not be able to establish an account if the necessary information is not received. The Fund may also place limits on account transactions while it is in the process of verifying your identity. Additionally, if the Fund is unable to verify your identity after your account is established, the Fund may be required to redeem your shares and close your account.

Suspension of Share Offering. The offering of Fund shares may be suspended during any period in which the determination of net asset value is suspended, and may be suspended by the Board at any time the Board believes it is in the Fund's best interest to do so.

SELLING SHARES. You can generally redeem (sell) some or all of your shares on any regular business day. You may redeem your shares by writing a letter, by wire, by telephone or on the internet. You can also set up an Automatic Withdrawal Plan to redeem shares on a regular basis. The redemption of Fund shares may be suspended under certain circumstances described in the Statement of Additional Information. If you have questions about any of these procedures, and especially if you are redeeming shares in a special situation, such as due to the death of the owner or from a retirement plan account, please call your financial intermediary or the Transfer Agent for assistance.

Redemption Price. Your shares will be redeemed at net asset value less any applicable sales charge or other fees. The net asset value used will be the next one calculated after your order is received, in proper form, by the Transfer Agent or your authorized financial intermediary. To be in proper form, your redemption order must comply with the procedures described below. The redemption price for shares will change from day-to-day because the value of the securities in the Fund's portfolio and the Fund's expenses fluctuate. The redemption price will normally differ for each class of shares. The redemption price of your shares may be more or less than their original cost.

Redemptions "In-Kind." Shares may be "redeemed in-kind" under certain circumstances (such as a lack of liquidity in the Fund's portfolio to meet redemptions). That means that the redemption proceeds will be paid in securities from the Fund's portfolio on a pro-rata basis, possibly including illiquid securities. If the Fund redeems your shares in-kind, you may bear transaction costs and will bear market risks until such securities are converted into cash.

Options for Receiving Redemption Proceeds:

• By Check. The Fund will normally send redemption proceeds by check to the address on your account statement.

• By AccountLink. If you have linked your Fund account to your bank account with AccountLink (described below), you may have redemption proceeds transferred directly into your account. Normally the transfer to your bank is initiated on the bank business day after the redemption. You will not receive dividends on the proceeds of redeemed shares while they are waiting to be transferred.

• By Wire. You can arrange to have redemption proceeds sent by Federal Funds wire to an account at a bank that is a member of the Federal Reserve wire system. The redemption proceeds will normally be transmitted on the next bank business day after the shares are redeemed. You will not receive dividends on the proceeds of redeemed shares while they are waiting to be transmitted.

Payment Delays. Payment for redeemed shares is usually made within seven days after the Transfer Agent receives redemption instructions in proper form. For accounts registered in the name of a broker-dealer, payment will normally be forwarded to the broker-dealer within three business days. The Transfer Agent may delay processing redemption payments for recently purchased shares until the purchase payment has cleared. That delay may be as much as five business days from the date the shares were purchased. That delay may be avoided if you purchase shares by Federal Funds wire or certified check. Under unusual circumstances, the right to redeem shares or the payment of redemption proceeds may be delayed or suspended as permitted under the Investment Company Act of 1940.

THE OPPENHEIMERFUNDS EXCHANGE PRIVILEGE. You can exchange all or part of your Fund shares for shares of the same class of other Oppenheimer funds that offer the exchange privilege. For example, you can exchange Class A shares of the Fund only for Class A shares of another fund. You can obtain a list of the Oppenheimer funds that are currently available for exchanges by calling a service representative at the telephone number on the back of this prospectus. The funds available for exchange can change from time to time. The Fund may amend, suspend or terminate the exchange privilege at any time. You will receive 60 days' notice of any material change in the exchange privilege unless applicable law allows otherwise.

The OppenheimerFunds exchange privilege affords investors the ability to switch their investments among Oppenheimer funds if their investment needs change. However, there are limits on that privilege. Frequent purchases, redemptions and exchanges of Fund shares may interfere with the Manager's ability to manage the Fund's investments efficiently, increase its transaction and administrative costs and/or affect its performance, depending on various factors, such as the size of the Fund, the nature of its investments, the amount of Fund assets a portfolio manager maintains in cash or cash equivalents, the aggregate dollar amount and the number and frequency of trades.

If large dollar amounts are involved in exchange or redemption transactions, the Fund might be required to sell portfolio securities at unfavorable times to meet those transaction requests, and the Fund's brokerage or administrative expenses might be increased. Therefore, the Manager and the Fund's Board have adopted the following policies and procedures to detect and prevent frequent and/or excessive exchanges or purchase and redemption activity, while addressing the needs of investors who seek liquidity in their investment and the ability to exchange shares as their investment needs change. There is no guarantee that those policies and procedures, described below, will be sufficient to identify and deter all excessive short-term trading.

Limitations on Frequent Exchanges

30-Day Hold. If a direct shareholder exchanges shares of another Oppenheimer fund account for shares of the Fund, his or her Fund account will be "blocked" from exchanges into any other fund for a period of 30 calendar days from the date of the exchange, subject to certain exceptions described below. Likewise, if a Fund shareholder exchanges Fund shares for shares of another eligible Oppenheimer fund, that fund account will be "blocked" from further exchanges for 30 calendar days. The block will apply to the full account balance and not just to the amount exchanged into the account. For example, if a shareholder exchanged $2,000 from one fund into another fund in which the shareholder already owned shares worth $10,000, then, following the exchange, the full account balance ($12,000 in this example) would be blocked from exchanges into another fund for a period of 30 calendar days. A shareholder whose account is registered on the Fund's books showing the name, address and tax ID number of the beneficial owner is a "direct shareholder."

Exceptions to 30-Day Hold

• Exchanges Into Money Market Funds. A direct shareholder will be permitted to exchange shares of a stock or bond fund for shares of an eligible money market fund any time, even if the shareholder has exchanged shares into the stock or bond fund during the prior 30 days. However, all of the shares held in that money market fund would then be blocked from further exchanges into another fund for 30 calendar days.

• Dividend Reinvestments and Class B Share Conversions. The reinvestment of dividends or distributions from one fund to purchase shares of another fund and the conversion of Class B shares into Class A shares will not be considered exchanges for purposes of imposing the 30-day limit.

• Asset Allocation Programs. Investment programs by Oppenheimer "funds-of-funds" that entail rebalancing investments in underlying Oppenheimer funds will not be subject to these limits. However, third-party asset allocation and rebalancing programs will be subject to the 30-day limit described above. Asset allocation firms that want to exchange shares held in accounts on behalf of their customers must identify themselves to the Transfer Agent and execute an acknowledgement and agreement to abide by these policies with respect to their customers' accounts. "On-demand" exchanges outside the parameters of portfolio rebalancing programs will also be subject to the 30-day limit.

• Automatic Exchange Plans. Accounts that receive exchange proceeds through automatic or systematic exchange plans that are established through the Transfer Agent will not be subject to the 30-day block as a result of those automatic or systematic exchanges but may be blocked from exchanges, under the 30-day limit, if they receive proceeds from other exchanges.

• Redemptions of Shares. These exchange policy limits do not apply to redemptions of shares. Shareholders are permitted to redeem their shares on any regular business day, subject to the terms of this prospectus.

Limitations on Exchanges in Omnibus Accounts. If you hold your Fund shares through a financial advisor or other firm such as a broker-dealer, a bank, an insurance company separate account, an investment adviser, an administrator or a trustee of a retirement plan that holds your shares in an account under its name (these are sometimes referred to as "omnibus" or "street name" accounts), that financial intermediary may impose its own restrictions or limitations to discourage short-term or excessive trading. You should consult your financial intermediary to find out what trading restrictions, including limitations on exchanges, may apply. The Fund, the Distributor, the Manager and the Transfer Agent encourage those financial intermediaries to apply the Fund's policies to their customers who invest indirectly in the Fund. However, the Transfer Agent may not be able to detect excessive short-term trading activity in accounts maintained in "omnibus" or "street name" form where the underlying beneficial owners are not identified. The Transfer Agent will attempt to monitor overall purchase and redemption activity in those accounts to seek to identify patterns that may suggest excessive trading by the underlying owners. If evidence of possible excessive trading activity is observed by the Transfer Agent, the financial intermediary that is the registered owner will be asked to review the account activity, and to confirm to the Transfer Agent and the Fund that appropriate action has been taken to curtail any excessive trading activity.

Other Limitations on Exchanges. There are a number of other special conditions and limitations that apply to certain types of exchanges. Those conditions and circumstances are described in the section "How to Exchange Shares" in the Statement of Additional Information. For information about sales charges that may apply to exchanges of shares see the sections "Contingent Deferred Sales Charge" and "Sales Charge Waivers" above.

Requirements for Exchanges of Shares. To exchange shares of the Fund, you must meet several conditions. The Fund may amend the following requirements at any time:

• Shares of the fund selected for exchange must be available for sale in your state of residence.

• The selected fund must offer the exchange privilege.

• You must meet the minimum purchase requirements for the selected fund.

• Generally, exchanges may be made only between identically registered accounts, unless all account owners send written exchange instructions with a signature guarantee.

• Before exchanging into a fund, you should obtain its prospectus and should read it carefully.

Timing of Exchange Transactions. Exchanged shares are normally redeemed from one fund and the proceeds are reinvested in the fund selected for exchange on the same regular business day on which the Transfer Agent or its agent (such as a financial intermediary holding the investor's shares in an "omnibus" or "street name" account) receives an exchange request that conforms to these policies. The request must be received by the close of the NYSE that day in order to receive that day's net asset value on the exchanged shares. For requests received after the close of the NYSE the shares being exchanged will be valued at the next net asset value calculated after the request is received. The Transfer Agent may delay transmitting the proceeds from an exchange for up to five business days, however, if it determines, in its discretion, that an earlier transmittal of the redemption proceeds would be detrimental to either the fund from which shares are being exchanged or the fund into which the exchange is being made. The exchange proceeds will be invested in the new fund at the next net asset value calculated after the proceeds are received. In the event that a delay in the reinvestment of proceeds occurs, the Transfer Agent will notify you or your financial intermediary.

Taxes on Exchanges. For tax purposes, an exchange of shares of the Fund is considered a sale of those shares and a purchase of the shares of the fund into which you are exchanging. Therefore, an exchange may result in a capital gain or loss for tax purposes.

OTHER LIMITS ON SHARE TRANSACTIONS. The Fund may impose other limits on transactions that it believes would be disruptive and may refuse any purchase or exchange order.

• Right to Refuse Purchase and Exchange Orders. The Distributor and/or the Transfer Agent may refuse any purchase or exchange order in their discretion and are not obligated to provide notice before rejecting an order.

• Right to Terminate or Suspend Account Privileges. The Transfer Agent may, in its discretion, limit or terminate trading activity by any person, group or account that it believes would be disruptive, even if the activity has not exceeded the policies outlined in this prospectus. As part of the Transfer Agent's procedures to detect and deter excessive trading activity, the Transfer Agent may review and consider the history of frequent trading activity in all accounts in the Oppenheimer funds known to be under common ownership or control. The Transfer Agent may send a written warning to a shareholder that the Transfer Agent believes may be engaging in disruptive or excessive trading activity; however, the Transfer Agent reserves the right to suspend or terminate the ability to purchase or exchange shares, with or without warning, for any account that the Transfer Agent determines, in the exercise of its discretion, has engaged in such trading activity.

SUBMITTING SHARE TRANSACTION REQUESTS. Share transactions may be requested by telephone or internet, in writing, through your financial intermediary, or by establishing one of the Investor Services plans described below. Certain transactions may also be submitted by fax. If an account has more than one owner, the Fund and the Transfer Agent may rely on instructions from any one owner or from the financial intermediary's representative of record for the account, unless that authority has been revoked.

Internet and Telephone Transaction Requests. Purchase, redemption and exchange requests may be submitted on the OppenheimerFunds website, www.oppenheimerfunds.com. Those requests may also be made by calling the telephone number on the back cover and either speaking to a service representative or accessing PhoneLink, the OppenheimerFunds automated telephone system that enables shareholders to perform certain account transactions automatically using a touch-tone phone.

You will need to obtain a user I.D. and password to execute transactions through PhoneLink or on the internet. Some internet and telephone transactions require the Oppenheimer AccountLink feature, described below, that links your Fund account with an account at a U.S. bank or other financial institution. The Transfer Agent will record any telephone calls to verify data concerning transactions.

The following policies apply to internet and telephone transactions:

• Purchases through AccountLink that are submitted through PhoneLink or on the internet are limited to $100,000.

• Purchases through AccountLink that are submitted by calling a service representative are limited to $250,000.

• Redemptions that are submitted by telephone or on the internet and request the proceeds to be paid by check, must be made payable to all owners of record of the shares and must be sent to the address on the account statement. Telephone or internet redemptions paid by check may not exceed $100,000 in any seven-day period. This service is not available within 15 days of changing the address on an account.

• Redemptions by telephone or on the internet that are sent to your bank account through AccountLink are not subject to any dollar limits.

• Exchanges submitted by telephone or on the internet may be made only between accounts that are registered with the same name(s) and address.

• Shares for which share certificates have been issued may not be redeemed or exchanged by telephone or on the internet.

• Shares held in an OppenheimerFunds-sponsored qualified retirement plan account may not be redeemed or exchanged by telephone or on the internet.

     The Transfer Agent has adopted procedures to confirm that telephone and internet instructions are genuine. Callers are required to provide service representatives with tax identification numbers and other account data and PhoneLink and internet users are required to use PIN numbers. The Transfer Agent will also send you written confirmations of share transactions. The Transfer Agent and the Fund will not be liable for losses or expenses that occur from telephone or internet instructions reasonably believed to be genuine.

Telephone or internet transaction privileges may be modified, suspended or terminated by the Fund at any time. The Fund will provide you notice of such changes whenever it is required to do so by applicable law. 

Purchases and Redemptions by Federal Funds Wire.  Shares purchased through the Distributor may be paid for by Federal Funds wire. Redemption proceeds may also be transmitted by wire. The minimum wire purchase or redemption is $2,500. There is a $10 fee for each wire redemption request. Before sending a wire purchase, call the Distributor's Wire Department at 1-800-225-5677 to notify the Distributor of the wire and to receive further instructions. To set up wire redemptions on your account or to arrange for a wire redemption, call the Transfer Agent at the telephone number on the back of this prospectus for information.

Written Transaction Requests. You can send purchase, exchange or redemption requests to the Transfer Agent at the address on the back cover. Your request must include:

• The Fund's name;

• For existing accounts, the Fund account number (from your account statement);

• For new accounts, a completed account application; 

• For purchases, a check payable to the Fund or to OppenheimerFunds Distributor, Inc.;

• For redemptions, any special payment instructions;

• For redemptions or exchanges, the dollar amount or number of shares to be redeemed or exchanged;

• For redemptions or exchanges, any share certificates that have been issued (exchanges or redemptions of shares for which certificates have been issued cannot be processed until the Transfer Agent receives the certificates);

• For individuals, the names and signatures of all registered owners exactly as they appear in the account registration;

• For corporations, partnerships or other businesses or as a fiduciary, the name of the entity as it appears in the account registration and the names and titles of any individuals signing on its behalf; and

• Other documents requested by the Transfer Agent to assure that the person purchasing, redeeming or exchanging shares is properly identified and has proper authorization to carry out the transaction.

Certain Requests Require a Signature Guarantee. To protect you and the Fund from fraud, certain redemption requests must be in writing and must include a signature guarantee. A notary public seal will not be accepted for these requests (other situations might also require a signature guarantee):

• You wish to redeem more than $100,000 and receive a check;

• The redemption check is not payable to all shareholders listed on the account statement;

• The redemption check is not sent to the address of record on your account statement;

• Shares are being transferred to a Fund account with a different owner or name; or 

• Shares are being redeemed by someone (such as an Executor) other than the owners.

Where Can You Have Your Signature Guaranteed? The Transfer Agent will accept a signature guarantee from a number of financial institutions, including:

• a U.S. bank, trust company, credit union or savings association,

• a foreign bank that has a U.S. correspondent bank,

• a U.S. registered dealer or broker in securities, municipal securities or government securities, or

• a U.S. national securities exchange, a registered securities association or a clearing agency.

Fax Requests. You may send requests for certain types of account transactions to the Transfer Agent by fax. Please call the number on the back of this prospectus for information about which transactions may be handled this way. Transaction requests submitted by fax are subject to the same rules and restrictions as the written, telephone and internet requests described in this prospectus.  However, requests that require a signature guarantee may not be submitted by fax. 

Submitting Transaction Requests Through Your Financial Intermediary. You can submit purchase, redemption or exchange requests through any broker, dealer or other financial intermediary that has a special agreement with the Distributor. The broker, dealer or other intermediary will place the order with the Distributor on your behalf. A broker or dealer may charge a processing fee for that service. If your shares are held in the name of your financial intermediary, you must redeem them through that intermediary.

Intermediaries that perform account transactions for their clients by participating in "Networking" through the National Securities Clearing Corporation are responsible for obtaining their clients' permission to perform those transactions, and are responsible to their clients who are shareholders of the Fund if the intermediary performs any transaction erroneously or improperly.

Client Account Exchanges by Financial Intermediaries. The Fund and the Transfer Agent permit brokers, dealers and other financial intermediaries to submit exchange requests on behalf of their customers, unless that authority has been revoked. The Fund or the Transfer Agent may limit or refuse exchange requests submitted by such financial intermediaries if, in the Transfer Agent's judgment, exercised in its discretion, the exchanges would be disruptive to any of the funds involved in the transaction.

• transmit funds electronically to purchase shares by internet, by telephone or automatically through an Asset Builder Plan. The purchase payment will be debited from your bank account. 

• have the Transfer Agent send redemption proceeds or dividends and distributions directly to your bank account. 

     AccountLink privileges should be requested on your account application or on your broker-dealer's settlement instructions if you buy your shares through a broker-dealer. For an established account, you can request AccountLink privileges by sending signature-guaranteed instructions and proper documentation to the Transfer Agent. AccountLink privileges will apply to each shareholder listed in the registration on the account as well as to the financial intermediary's representative of record unless and until the Transfer Agent terminates or receives written instructions terminating or changing those privileges. After you establish AccountLink for your account, any change you make to your bank account information must be made by signature-guaranteed instructions to the Transfer Agent signed by all shareholders on the account. Please call the Transfer Agent for more information.

Asset Builder Plan. Under an Asset Builder Plan, you may purchase shares of the Fund automatically. An Asset Builder Plan is available only if you have established AccountLink with a bank or other financial institution. Payments to purchase Fund shares will be debited from your linked account.

To establish an Asset Builder Plan at the time you initially purchase Fund shares, complete the "Asset Builder Plan" information on the account application. To add an Asset Builder Plan to an existing account, use the Asset Builder Enrollment Form. You may change the amount of your Asset Builder payment or you can terminate your automatic investments at any time by writing to the Transfer Agent. The Transfer Agent requires a reasonable period (approximately 10 days) after receipt of your instructions to implement the requested changes. For more details, see the account application, the Asset Builder Enrollment Form and the Statement of Additional Information. Those documents are available by contacting the Distributor or may be downloaded from our website at www.oppenheimerfunds.com. The Fund reserves the right to amend, suspend or discontinue offering Asset Builder Plans at any time without prior notice.

Automatic Redemption and Exchange Plans. The Fund has several plans that enable you to redeem shares automatically or exchange them for shares of another Oppenheimer fund on a regular basis. Please call the Transfer Agent or consult the Statement of Additional Information for details.

Less Paper, Less Waste. To avoid sending duplicate copies of Fund materials to households, the Fund will mail only one copy of each prospectus, annual and semi-annual report and annual notice of the Fund's privacy policy to shareholders having the same last name and address on the Fund's records. The consolidation of these mailings, called "householding," benefits the Fund through lower printing costs and reduced mailing expense.

If you prefer to receive multiple copies of these materials, you may call the Transfer Agent at the number on the back of this prospectus or you may notify the Transfer Agent in writing. Multiple copies of prospectuses, reports and privacy notices will be sent to you commencing within 30 days after the Transfer Agent receives your request to stop householding.

DISTRIBUTION AND SERVICE (12b-1) PLANS

Service Plan for Class A Shares. The Fund has adopted a Service Plan for Class A shares that reimburses the Distributor for a portion of the costs of maintaining accounts and providing services to Class A shareholders. Reimbursement is made periodically at an annual rate of up to 0.25% of the Class A shares daily net assets. The Distributor currently uses all of those fees to pay brokers, dealers, banks and other financial intermediaries for providing personal service and maintaining the 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. Because the service fee is paid out of the Fund's assets on an ongoing basis, over time it will increase the cost of your investment.

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 pay the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. Under the plans, the Fund pays the Distributor an asset-based sales charge for Class B and Class C shares calculated at an annual rate of 0.75% of the daily net assets of those classes. The Fund also pays a service fee under the plans at an annual rate of 0.25% of the daily net assets of Class B and Class C. Altogether, these fees increase the Class B and Class C annual expenses by 1.00%, calculated on the daily net assets of the applicable class. Because these fees are paid out of the Fund's assets on an on going basis, over time they will increase the cost of your investment and may cost you more than other types of sales charges.

     Use of Plan Fees: The Distributor uses the service fees to compensate brokers, dealers, banks and other financial intermediaries for maintaining accounts and providing personal services to Class B and Class C shareholders in the applicable share class. The Distributor normally pays intermediaries the 0.25% service fee in advance for the first year after shares are purchased and then pays that fee periodically.

     Class B Shares: The Distributor currently pays a sales concession of 3.75% of the purchase price of Class B shares to dealers from its own resources at the time of sale. Including the advance of the service fee, the total amount paid by the Distributor to the dealer at the time of sale of Class B shares is therefore 4.00% of the purchase price. The Distributor normally retains the Class B asset-based sales charge. For ongoing purchases of Class B shares by certain retirement plans, the Distributor may pay the intermediary the asset-based sales charge and service fee during the first year after purchase instead of paying a sales concession and the first year's service fees at the time of purchase. See the Statement of Additional Information for exceptions.

     Class C Shares: At the time of a Class C share purchase, the Distributor generally pays financial intermediaries a sales concession of 0.75% of the purchase price from its own resources. Therefore, the total amount, including the advance of the service fee, that the Distributor pays the intermediary at the time of a Class C share purchase is 1.00% of the purchase price. The Distributor normally retains the asset-based sales charge on Class C share purchases during the first year and then pays that fee to the intermediary as an ongoing concession. See the Statement of Additional Information for exceptions to these arrangements.

PAYMENTS TO FINANCIAL INTERMEDIARIES AND SERVICE PROVIDERS. The Manager and the Distributor, in their discretion, may also make payments to brokers, dealers and other financial intermediaries or to service providers for distribution and/or shareholder servicing activities. Those payments are made out of the Manager's and/or the Distributor's own resources and/or assets, including from the revenues or profits derived from the advisory fees the Manager receives from the Fund. Those cash payments, which may be substantial, are paid to many firms having business relationships with the Manager and Distributor and are in addition to any distribution fees, servicing fees, or transfer agency fees paid directly or indirectly by the Fund to these financial intermediaries and any commissions the Distributor pays to these firms out of the sales charges paid by investors. Payments by the Manager or Distributor from their own resources are not reflected in the tables in the "Fees and Expenses of the Fund" section of this prospectus because they are not paid by the Fund.

      The financial intermediaries that may receive those payments include firms that offer and sell Fund shares to their clients, or provide shareholder services to the Fund, or both, and receive compensation for those activities. The financial intermediaries that may receive payments include your securities broker, dealer or financial advisor, sponsors of fund "supermarkets," sponsors of fee-based advisory or wrap fee programs, sponsors of college and retirement savings programs, banks, trust companies and other intermediaries offering products that hold Fund shares, and insurance companies that offer variable annuity or variable life insurance products.

In general, these payments to financial intermediaries can be categorized as "distribution-related" or "servicing" payments. Payments for distribution-related expenses, such as marketing or promotional expenses, are often referred to as "revenue sharing." Revenue sharing payments may be made on the basis of the sales of shares attributable to that intermediary, the average net assets of the Fund and other Oppenheimer funds attributable to the accounts of that intermediary and its clients, negotiated lump sum payments for distribution services provided, or similar fees. In some circumstances, revenue sharing payments may create an incentive for a financial intermediary or its representatives to recommend or offer shares of the Fund or other Oppenheimer funds to its customers. These payments also may give an intermediary an incentive to cooperate with the Distributor's marketing efforts. A revenue sharing payment may, for example, qualify the Fund for preferred status with the intermediary receiving the payment or provide representatives of the Distributor with access to representatives of the intermediary's sales force, in some cases on a preferential basis over funds of competitors. Additionally, as firm support, the Manager or Distributor may reimburse expenses related to educational seminars and "due diligence" or training meetings (to the extent permitted by applicable laws or the rules of the Financial Industry Regulatory Authority ("FINRA")) designed to increase sales representatives' awareness about Oppenheimer funds, including travel and lodging expenditures. However, the Manager does not consider a financial intermediary's sale of shares of the Fund or other Oppenheimer funds when selecting brokers or dealers to effect portfolio transactions for the funds.

Various factors are used to determine whether to make revenue sharing payments. Possible considerations include, without limitation, the types of services provided by the intermediary, sales of Fund shares, the redemption rates on accounts of clients of the intermediary or overall asset levels of Oppenheimer funds held for or by clients of the intermediary, the willingness of the intermediary to allow the Distributor to provide educational and training support for the intermediary's sales personnel relating to the Oppenheimer funds, the availability of the Oppenheimer funds on the intermediary's sales system, as well as the overall quality of the services provided by the intermediary and the Manager or Distributor's relationship with the intermediary. The Manager and Distributor have adopted guidelines for assessing and implementing each prospective revenue sharing arrangement. To the extent that financial intermediaries receiving distribution-related payments from the Manager or Distributor sell more shares of the Oppenheimer funds or retain more shares of the funds in their client accounts, the Manager and Distributor benefit from the incremental management and other fees they receive with respect to those assets.

Payments may also be made by the Manager, the Distributor or the Transfer Agent to financial intermediaries to compensate or reimburse them for administrative or other client services provided such as sub-transfer agency services for shareholders or retirement plan participants, omnibus accounting or sub-accounting, participation in networking arrangements, account set-up, recordkeeping and other shareholder services. Payments may also be made for administrative services related to the distribution of Fund shares through the intermediary. Firms that may receive servicing fees include retirement plan administrators, qualified tuition program sponsors, banks and trust companies, and others. These fees may be used by the service provider to offset or reduce fees that would otherwise be paid directly to them by certain account holders, such as retirement plans.

     The Statement of Additional Information contains more information about revenue sharing and service payments made by the Manager or the Distributor. Your broker, dealer or other financial intermediary may charge you fees or commissions in addition to those disclosed in this prospectus. You should ask your financial intermediary for details about any such payments it receives from the Manager or the Distributor and their affiliates, or any other fees or expenses it charges.

Dividends, Capital Gains and Taxes

DIVIDENDS. The Fund intends to declare dividends separately for each class of shares from net tax-exempt income and/or net taxable investment income each regular business day and to pay those dividends monthly. Daily dividends will not be declared or paid on newly-purchased shares until Federal Funds are available to the Fund from the purchase payment for such shares.

The Fund attempts to pay dividends on Class A shares at a constant level. There is no assurance that it will be able to do so. The Board of Trustees may change the targeted dividend level at any time, without prior notice to shareholders. The amount of those dividends and any other distributions paid on other classes of shares may vary over time, depending on market conditions, the composition of the Fund's portfolio, and expenses borne by the particular class of shares. Dividends and other distributions paid on Class A shares will generally be higher than dividends for Class B and Class C shares, which normally have higher expenses than Class A. The Fund cannot guarantee that it will pay any dividends or other distributions.

CAPITAL GAINS. Although the Fund does not seek capital gains, it may realize capital gains on the sale of portfolio securities. If it does, it may make distributions out of any net short-term or long-term capital gains annually. The Fund may also make supplemental distributions of ordinary income and exempt-interest dividends and capital gains following the end of its fiscal year. There can be no assurance that the Fund will pay any capital gains distributions in a particular year. Long-term capital gains will be separately identified in the tax information the Fund sends you after the end of the calendar year.

Options for Receiving Dividends and Distributions. When you open your Fund account, you can specify on your application how you want to receive distributions of dividends and capital gains. To change that option, you must notify the Transfer Agent. There are four payment options available:

• Reinvest All Distributions in the Fund. You can elect to reinvest all dividends and capital gains distributions in additional shares of the Fund.

• Reinvest Only Dividends or Capital Gains. You can elect to reinvest some types of distributions in the Fund while receiving the other types of distributions by check or having them sent to your bank account through AccountLink. Different treatment is available for distributions of dividends, short-term capital gains and long-term capital gains.

• Receive All Distributions in Cash. You can elect to receive all dividends and capital gains distributions by check or have them sent to your bank through AccountLink.

• Reinvest Your Distributions in Another Oppenheimer Fund. You can reinvest all of your dividends and capital gains distributions in another Oppenheimer fund that is available for exchanges. You must have an existing account in the same share class in the selected fund.

TAXES. Dividends paid from net investment income earned by the Fund on tax-exempt municipal securities will be excludable from gross income for federal income tax purposes. All or a portion of the dividends paid by the Fund that are derived from interest paid on certain "private activity bonds" may be an item of tax preference if you are subject to the federal alternative minimum tax. The portion of the Fund's exempt-interest dividends that was a tax preference item for the most recent calendar year is available on the OppenheimerFunds website at www.oppenheimerfunds.com. Under the heading "Planning and Research," click on the link "Tax Center" and under the "Your Investment Service Center" heading, click "Supplemental Tax Information," then click the link "Municipal Income/Tax Preference Percentage Tables." Finally, under the heading "Exempt-interest Dividends" click "Tax Preference Percentages," which brings up the 2009 Alternative Minimum Tax percentages for your Fund.  This amount will vary from year to year.

Dividends and capital gains distributions may be subject to federal, state or local taxes. Any short-term capital gain distributions are taxable to you as ordinary income. Any long-term capital gain distributions are taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund. The Fund may derive gains in part from municipal obligations the Fund purchased below their principal or face values. All, or a portion of these gains may be taxable to you as ordinary income rather than capital gains. Whether you reinvest your distributions in additional shares or take them in cash, the tax treatment is the same.

After the end of each calendar year the Fund will send you and the Internal Revenue Service statements showing the amount of any taxable distributions you received in the previous year and will separately identify any portion of these distributions that qualify for taxation as long-term capital gains or for any other special tax treatment.

North Carolina Tax Considerations. Unless the act authorizing the issuance of the obligation expressly states otherwise, exempt interest dividends earned by residents of North Carolina should not be subject to federal, North Carolina state or North Carolina local taxes to the extent that such exempt interest dividends represent interest from bonds issued by North Carolina, its political subdivisions, or commissions, authorities, or other agencies of North Carolina or its political subdivisions or on income derived from direct obligations of the U.S. Government or its possessions. The portion of the Fund's dividends that are attributable to income earned on other obligations (non-North Carolina municipal securities) will normally be subject to personal income taxes imposed by the State of North Carolina and its political subdivisions.

     Every year your Fund will send you and the Internal Revenue Service a statement showing the amount of any taxable distribution you received in the previous year. The Fund will also send you a separate statement summarizing the total distributions paid by that Fund.

Other Taxability Risk Considerations. It is possible that, because of events occurring after the date of its issuance, a municipal security owned by the Fund will be determined to pay interest that is includable in gross income for purposes of the federal income tax, and that determination could be retroactive to the date of issuance. Such a determination may cause a portion of prior distributions to shareholders to be taxable to shareholders in the year of receipt.

Legislation affecting tax-exempt municipal securities is often considered by the United States Congress and legislation affecting the exemption of interest or other income thereon for purposes of taxation by a state may be considered by the state's legislature. Court proceedings may also be filed, the outcome of which could modify the tax treatment of a state's municipal securities. There can be no assurance that legislation enacted or proposed, or actions by a court, after the date of issuance of a municipal security will not have an adverse effect on the tax status of interest or other income or the market value of that municipal security. Please consult your tax adviser regarding pending or proposed federal and state tax legislation, court proceedings and other tax considerations.

Qualification as a Regulated Investment Company. The Fund intends each year to qualify as a "regulated investment company" under the Internal Revenue Code, but reserves the right not to qualify. The Fund qualified during its most recent fiscal year. The Fund, as a regulated investment company, will not be subject to federal income taxes on any of its income, provided that it satisfies certain income, diversification and distribution requirements.

Additional Information About the Fund's Investment Policies and Risks

The investment objective, the principal investment policies and the main risks of the Fund are described in the Prospectus. This SAI contains supplemental information about those policies and risks and the types of securities in which the Fund can invest. Additional information is also provided about the strategies that the Fund may use to try to achieve its investment objective.

The composition of the Fund's portfolio and the techniques and strategies that the Fund uses in selecting portfolio securities may vary over time. The Fund is not required to use all of the investment techniques and strategies described below in seeking its investment objective. It may use some of the investment techniques and strategies only at some times or it may not use them at all.

The Fund's municipal securities that are held to maturity are redeemable by the security's issuer at full principal value plus accrued interest. The values of those securities held by the Fund, however, may be affected by changes in general interest rates and other factors prior to their maturity. Because the current value of debt securities varies inversely with changes in prevailing interest rates, if interest rates increased after a security was purchased, that security will normally decline in value. Conversely, should interest rates decrease after a security was purchased, normally its value would rise.

Those fluctuations in value will not generally result in realized gains or losses to the Fund unless the Fund sells the security prior to the security's maturity. The Fund may dispose of securities prior to their maturity for investment purposes. In that case, the Fund could realize a capital gain or loss on the sale.

There are variations in the credit quality of municipal securities, both within a particular rating category and between categories. These variations depend on numerous factors. The yields of municipal securities depend on a number of factors, including general conditions in the municipal securities market, the size of a particular offering, the maturity of the obligation and rating (if any) of the issue. These factors are discussed in greater detail below.

Unless the Prospectus or SAI states that an investment percentage restriction applies on an ongoing basis, it applies only at the time the Fund makes an investment (except for borrowing and investments in illiquid securities). This means the Fund does not have to buy or sell securities solely to meet percentage limits if those limits were not met because the value of the investment changed in proportion to the size of the Fund.

The Fund's Main Investment Policies

Municipal Securities. The types of municipal securities in which the Fund may invest and the Fund's principal investment strategies are described in the prospectus under "Principle Investment Strategies" and "About the Fund's Investments". Municipal securities are generally classified as general obligation bonds, revenue bonds and notes. A discussion of the general characteristics of these principal types of municipal securities follows below.

Under normal market conditions, and as a fundamental policy, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in securities the income from which, in the opinion of counsel to the issuer of each security, is exempt from both federal and state individual income tax, which may include securities of issuers located outside of the Fund's state such as U.S. territories, commonwealths and possessions. Securities that generate income subject to alternative minimum tax (AMT) will count towards the Fund's 80% requirement. The Fund selects investments without regard to this type of tax treatment.

Municipal Bonds. Long-term municipal securities which have a maturity of more than one year (when issued) are classified as "municipal bonds." The principal classifications of long-term municipal bonds are "general obligation" bonds and "revenue" bonds (including "private activity" bonds). They may have fixed, variable or floating rates of interest or may be "zero-coupon" bonds, as described below.

Some bonds may be "callable," allowing the issuer to redeem them before their maturity date. To protect bondholders, callable bonds may be issued with provisions that prevent them from being called for a period of time. Typically, that is 5 to 10 years from the issuance date. When interest rates decline, if the call protection on a bond has expired, it is more likely that the issuer may call the bond. If that occurs, the Fund might have to reinvest the proceeds of the called bond in bonds that pay a lower rate of return. In turn that could reduce the Fund's yield.

General Obligation Bonds. The basic security behind general obligation bonds is the issuer's pledge of its full faith and credit and taxing, if any, power for the repayment of principal and the payment of interest. Issuers of general obligation bonds include states, counties, cities, towns, and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including construction or improvement of schools, highways and roads, and water and sewer systems. The rate of taxes that can be levied for the payment of debt service on these bonds may be limited or unlimited. Additionally, there may be limits as to the rate or amount of special assessments that can be levied to meet these obligations.

Revenue Bonds. The principal security for a revenue bond is generally the net revenues derived from a particular facility, group of facilities, or, in some cases, the proceeds of a special excise tax or other specific revenue source, such as a state's or local government's proportionate share of the tobacco Master Settlement Agreement ("MSA") (as described in the section titled "Tobacco Related Bonds"). Revenue bonds are issued to finance a wide variety of capital projects. Examples include electric, gas, water and sewer systems; highways, bridges, and tunnels; port and airport facilities; colleges and universities; and hospitals.

Although the principal security for revenue bonds may vary from bond to bond, many provide additional security in the form of a debt service reserve fund that may be used to make principal and interest payments on the issuer's obligations. Housing finance authorities have a wide range of security, including partially or fully insured mortgages, rent subsidized and/or collateralized mortgages, and/or the net revenues from housing or other public projects. Some authorities provide further security in the form of a state's ability (without obligation) to make up deficiencies in the debt service reserve fund.

Private Activity Bonds. The Tax Reform Act of 1986 amended and reorganized the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), including the rules governing tax-exemption for interest on certain types of municipal securities known as "private activity bonds" (or, "industrial development bonds" as they were referred to under pre-1986 law). The proceeds from private activity bonds are used to finance various non-governmental privately owned and/or operated facilities. Under the Internal Revenue Code, interest on private activity bonds is excludable from gross income for federal income tax purposes if (i) the financed activities fall into one of seven categories of "qualified private activity bonds," consisting of mortgage bonds, veterans mortgage bonds, small issue bonds, student loan bonds, redevelopment bonds, exempt facility bonds and 501(c)(3) bonds, and (ii) certain tests are met. The types of facilities that may be financed with exempt facility bonds include airports, docks and wharves, water furnishing facilities, sewage facilities, solid waste disposal facilities, qualified residential rental projects, hazardous waste facilities and high speed intercity rail facilities. The types of facilities that may be financed with 501(c)(3) bonds include hospitals and educational facilities that are owned by 501(c)(3) organizations.

Whether a municipal security is a private activity bond (the interest on which is taxable unless it is a qualified private activity bond) depends on whether (i) more than a certain percentage (generally 10%) of (a) the proceeds of the security are used in a trade or business carried on by a non-governmental person and (b) the payment of principal or interest on the security is directly or indirectly derived from such private use, or is secured by privately used property or payments in respect of such property, or (ii) more than the lesser of 5% of the issue or $5 million is used to make or finance loans to non-governmental persons.

Moreover, a private activity bond of certain types that would otherwise be a qualified tax-exempt private activity bond will not, under Internal Revenue Code Section 147(a), be a qualified bond for any period during which it is held by a person who is a "substantial user" of the facilities financed by the bond, or a "related person" of such a substantial user. Generally a "substantial user" is a non-exempt person who regularly uses part of a facility in a trade or business.

Thus, certain municipal securities could lose their tax-exempt status retroactively if the issuer or user fails to meet certain continuing requirements, for the entire period during which the securities are outstanding, as to the use and operation of the bond-financed facilities and the use and expenditure of the proceeds of such securities. The Fund makes no independent investigation into the use of such facilities or the expenditure of such proceeds. If the Fund should hold a bond that loses its tax-exempt status retroactively, there might be an adjustment to the tax-exempt income previously distributed to shareholders.

The payment of the principal and interest on such qualified private activity bonds is dependant solely on the ability of the facility's user to meet its financial obligations, generally from the revenues derived from the operation of the financed facility, and the pledge, if any, of real and personal property financed by the bond as security for those payments.

Limitations on the amount of private activity bonds that each state may issue may reduce the supply of such bonds. The value of the Fund's portfolio could be affected by these limitations if they reduce the availability of such bonds.

Interest on certain qualified private activity bonds that is tax-exempt may nonetheless be treated as a tax preference item subject to the alternative minimum tax to which certain taxpayers are subject. If such qualified private activity bonds are held by the Fund, a proportionate share of the exempt-interest dividends paid by the Fund would constitute an item of tax preference to such shareholders.

Municipal Notes. Municipal securities having a maturity (when the security is issued) of less than one year are generally known as municipal notes. Municipal notes generally are used to provide for short-term working capital needs. Some of the types of municipal notes the Fund can invest in are described below.

Tax Anticipation Notes. These are issued to finance working capital needs of municipalities. Generally, they are issued in anticipation of various seasonal tax revenue, such as income, sales, use or other business taxes, and are payable from these specific future taxes.

Revenue Anticipation Notes. These are notes issued in expectation of receipt of other types of revenue, such as federal revenues available under federal revenue-sharing programs.

Bond Anticipation Notes. Bond anticipation notes are issued to provide interim financing until long-term financing can be arranged. The long-term bonds that are issued typically also provide the money for the repayment of the notes.

Construction Loan Notes. These are sold to provide project construction financing until permanent financing can be secured. After successful completion and acceptance of the project, it may receive permanent financing through public agencies, such as the Federal Housing Administration.

Tax-Exempt Commercial Paper. This type of short-term obligation (usually having a maturity of 270 days or less) is issued by a municipality to meet current working capital needs.

Auction Rate Securities. Auction rate securities are municipal debt instruments with long-term nominal maturities for which the interest rate is reset at specific shorter frequencies (typically every 7-35 days) through a "dutch" auction process. A dutch auction is a competitive bidding process used to determine rates on each auction date. In a dutch auction, a broker-dealer submits bids, on behalf of current and prospective investors, to the auction agent. The winning bid rate is the rate at which the auction "clears", meaning the lowest possible interest rate at which all the securities can be sold at par. This "clearing rate" is paid on the entire issue for the upcoming period and includes current holders of the auction rate securities. Investors who bid a minimum rate above the clearing rate receive no securities, while those whose minimum bid rates were at or below the clearing rate receive the clearing rate for the next period.

While the auction rate process is designed to permit the holder to sell the auction rate securities in an auction at par value at specified intervals, there is the risk that an auction will fail due to insufficient demand for the securities. Auction rate securities may be subject to changes in interest rates, including decreased interest rates. Failed auctions may impair the liquidity of auction rate securities.

Municipal Lease Obligations. The Fund's investments in municipal lease obligations may be through certificates of participation that are offered to investors by public entities. Municipal leases may take the form of a lease or an installment purchase contract issued by a state or local government authority to obtain funds to acquire a wide variety of equipment and facilities.

Some municipal lease securities may be deemed to be "illiquid" securities. The Manager may determine that certain municipal leases are liquid under specific guidelines that require the Manager to evaluate:

• the frequency of trades and price quotations for such securities;

• the number of dealers or other potential buyers willing to purchase or sell such securities;

• the availability of market-makers; and

• the nature of the trades for such securities.

While the Fund holds such securities, the Manager will also evaluate the likelihood of a continuing market for these securities and their credit quality.

Municipal leases have special risk considerations. Although lease obligations do not constitute general obligations of the municipality for which the municipality's taxing power is pledged, a lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for that purpose on a yearly basis. While the obligation might be secured by the lease, it might be difficult to dispose of that property in case of a default.

Projects financed with certificates of participation generally are not subject to state constitutional debt limitations or other statutory requirements that may apply to other municipal securities. Payments by the public entity on the obligation underlying the certificates are derived from available revenue sources. That revenue might be diverted to the funding of other municipal service projects. Payments of interest and/or principal with respect to the certificates are not guaranteed and do not constitute an obligation of a state or any of its political subdivisions.

Municipal leases may also be subject to "abatement risk." The leases underlying certain municipal lease obligations may state that lease payments are subject to partial or full abatement. That abatement might occur, for example, if material damage to or destruction of the leased property interferes with the lessee's use of the property. However, in some cases that risk might be reduced by insurance covering the leased property, or by the use of credit enhancements such as letters of credit to back lease payments, or perhaps by the lessee's maintenance of reserve monies for lease payments.

In addition to the risk of "non-appropriation," municipal lease securities do not have as highly liquid a market as conventional municipal bonds. Municipal leases, like other municipal debt obligations, are subject to the risk of non-payment of interest or repayment of principal by the issuer. The ability of issuers of municipal leases to make timely lease payments may be adversely affected in general economic downturns and as relative governmental cost burdens are reallocated among federal, state and local governmental units. A default in payment of income would result in a reduction of income to the Fund. It could also result in a reduction in the value of the municipal lease and that, as well as a default in repayment of principal, could result in a decrease in the net asset value of the Fund.

TOBACCO RELATED BONDS. The Fund may invest in two types of tobacco related bonds: (i) tobacco settlement revenue bonds, for which payments of interest and principal are made solely from a state's interest in the MSA described below, and (ii) tobacco bonds subject to a state's appropriation pledge, for which payments may come from both the MSA revenue and the applicable state's appropriation pledge.

Tobacco Settlement Revenue Bonds. The Fund may invest up to 25% (measured at the time of purchase) of its total assets in tobacco settlement revenue bonds. Tobacco settlement revenue bonds are secured by an issuing state's proportionate share in the MSA. The MSA is an agreement reached out of court in November 1998 between 46 states and six other U.S. jurisdictions (including Puerto Rico and Guam) and the four largest (now three) U.S. tobacco manufacturers (Philip Morris, RJ Reynolds, Brown & Williamson (merged with RJ Reynolds in 2004), and Lorillard). Subsequently, a number of smaller tobacco manufacturers signed on to the MSA. The MSA provides for payments annually by the manufacturers to the states and jurisdictions in perpetuity, in exchange for releasing all claims against the manufacturers and a pledge of no further litigation. The MSA established a base payment schedule and a formula for adjusting payments each year. Tobacco manufacturers pay into a master escrow trust based on their market share and each state receives a fixed percentage of the payment as set forth in the MSA.

A number of states have securitized the future flow of those payments by selling bonds pursuant to indentures, some through distinct governmental entities created for such purpose. The bonds are backed by the future revenue flow that is used for principal and interest payments on the bonds. Annual payments on the bonds, and thus the risk to the Fund, are highly dependent on the receipt of future settlement payments by the state or its governmental entity, as well as other factors. The actual amount of future settlement payments is dependent on many factors including, but not limited to, annual domestic cigarette shipments, cigarette consumption, inflation and the financial capability of participating tobacco companies. As a result, payments made by tobacco manufacturers could be reduced if the decrease in tobacco consumption is significantly greater than the forecasted decline.

On June 22, 2009, President Obama signed into law the "Family Smoking Prevention and Tobacco Control Act" which extends the authority of the U.S. Food and Drug Administration to encompass the regulation of tobacco products. Among other things, the legislation authorizes the FDA to adopt product standards for tobacco products, restrict advertising of tobacco products, and impose stricter warning labels. FDA regulation of tobacco products could result in greater decreases in tobacco consumption than originally forecasted.  On August 31, 2009, a number of tobacco manufacturers filed suit in federal court in Kentucky alleging that certain of the provisions of the FDA Tobacco Act restricting the advertising and marketing of tobacco products are inconsistent with the freedom of speech guarantees of the First Amendment of the United States Constitution. The suit does not challenge Congress' decision to give the FDA regulatory authority over tobacco products or the vast majority of the provisions of the law.

Because tobacco settlement bonds are backed by payments from the tobacco manufacturers, and generally not by the credit of the state or local government issuing the bonds, their creditworthiness depends on the ability of tobacco manufacturers to meet their obligations. A market share loss by the MSA companies to non-MSA participating tobacco manufacturers could also cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy also could cause delays or reductions in bond payments, which could affect the Fund's net asset value.

The MSA and tobacco manufacturers have been and continue to be subject to various legal claims. An adverse outcome to any litigation matters relating to the MSA or affecting tobacco manufacturers could adversely affect the payment streams associated with the MSA or cause delays or reductions in bond payments by tobacco manufacturers. The MSA itself has been subject to legal challenges and has, to date, withstood those challenges.

Tobacco Bonds Subject to Appropriation (STA) Bonds. In addition to the tobacco settlement bonds discussed above, the Fund also may invest in tobacco related bonds that are subject to a state's appropriation pledge ("STA Tobacco Bonds"). STA Tobacco Bonds rely on both the revenue source from the MSA and a state appropriation pledge.

These STA Tobacco Bonds are part of a larger category of municipal bonds that are subject to state appropriation. Although specific provisions may vary among states, "subject to appropriation bonds" (also referred to as "appropriation debt") are typically payable from two distinct sources: (i) a dedicated revenue source such as a municipal enterprise, a special tax or, in the case of tobacco bonds, the MSA funds, and (ii) the issuer's general funds. Appropriation debt differs from a state's general obligation debt in that general obligation debt is backed by the state's full faith, credit and taxing power, while appropriation debt requires the state to pass a specific periodic appropriation to pay interest and/or principal on the bonds as the payments come due. The appropriation is usually made annually. While STA Tobacco Bonds offer an enhanced credit support feature, that feature is generally not an unconditional guarantee of payment by a state and states generally do not pledge the full faith, credit or taxing power of the state. The Fund considers the STA Tobacco Bonds to be "municipal securities" for purposes of its concentration policies.

Litigation Challenging the MSA. The participating manufacturers and states in the MSA are subject to several pending lawsuits challenging the MSA and/or related state legislation or statutes adopted by the states to implement the MSA (referred to herein as the "MSA-related legislation"). One or more of the lawsuits allege, among other things, that the MSA and/or the states' MSA-related legislation are void or unenforceable under the Commerce Clause and certain other provisions of the U.S. Constitution, the federal antitrust laws, federal civil rights laws, state constitutions, consumer protection laws and unfair competition laws.

To date, challenges to the MSA or the states' MSA-related legislation have not been ultimately successful, although several such challenges have survived initial appellate review of motions to dismiss or have proceeded to a stage of litigation where the ultimate outcome may be determined by, among other things, findings of fact based on extrinsic evidence as to the operation and impact of the MSA and the states' MSA-related legislation.

New York state officials are defendants in a lawsuit pending in the United States District Court for the Southern District of New York in which cigarette importers allege that the MSA and/or related legislation violates federal antitrust laws and the Commerce Clause of the United States Constitution. In a separate proceeding pending in the same court, plaintiffs assert the same theories against not only New York officials but also the Attorneys General for thirty other states. The United States Court of Appeals for the Second Circuit has held that the allegations in both actions, if proven, establish a basis for relief on antitrust and Commerce Clause grounds and that the trial courts in New York have personal jurisdiction sufficient to enjoin other states' officials from enforcing their MSA-related legislation. On remand in those two actions, one trial court has granted summary judgment for the New York officials and lifted a preliminary injunction against New York officials' enforcement against plaintiffs of the state's "allocable share" amendment to the MSA's Model Escrow Statute; the other trial court has held that plaintiffs are unlikely to succeed on the merits. The former decision is on appeal to the United States Court of Appeals for the Second Circuit.

In another action, the United States Court of Appeals for the Fifth Circuit reversed a trial court's dismissal of challenges to MSA-related legislation in Louisiana under the First and Fourteenth Amendments to the United States Constitution. On remand in that case, and in another case filed against the Louisiana Attorney General, trial courts have granted summary judgment for the Louisiana Attorney General. One of those decisions is on appeal to the United States Court of Appeals for the Fifth Circuit. The deadline to appeal the other decision has not yet expired.

The United States Courts of Appeals for the Sixth, Eighth, Ninth and Tenth Circuits have affirmed dismissals or grants of summary judgment in favor of state officials in four other cases asserting antitrust and constitutional challenges to the allocable share amendment legislation in those states.

Another proceeding has been initiated before an international arbitration tribunal under the provisions of the North American Free Trade Agreement. A hearing on the merits that was scheduled for June 2009 has been continued.

The MSA and states' MSA-related legislation may also continue to be challenged in the future. A determination that the MSA or states' MSA-related legislation is void or unenforceable would have a material adverse effect on the payments made by the participating manufacturers under the MSA.

Litigation Seeking Monetary Relief from Tobacco Industry Participants. The tobacco industry has been the target of litigation for many years. Both individual and class action lawsuits have been brought by or on behalf of smokers alleging that smoking has been injurious to their health, and by non-smokers alleging harm from environmental tobacco smoke, also known as "secondhand smoke." Plaintiffs seek various forms of relief, including compensatory and punitive damages aggregating billions of dollars, treble/multiple damages and other statutory damages and penalties, creation of medical monitoring and smoking cessation funds, disgorgement of profits, legal fees, and injunctive and equitable relief.

The MSA does not release participating manufacturers from liability in either individual or class action cases. Healthcare cost recovery cases have also been brought by governmental and non-governmental healthcare providers seeking, among other things, reimbursement for healthcare expenditures incurred in connection with the treatment of medical conditions allegedly caused by smoking. The participating manufacturers are also exposed to liability in these cases, because the MSA only settled healthcare cost recovery claims of the participating states. Litigation has also been brought against certain participating manufacturers and their affiliates in foreign countries.

The ultimate outcome of any pending or future lawsuit is uncertain. Verdicts of substantial magnitude that are enforceable as to one or more participating manufacturers, if they occur, could encourage commencement of additional litigation, or could negatively affect perceptions of potential triers of fact with respect to the tobacco industry, possibly to the detriment of pending litigation. An unfavorable outcome or settlement or one or more adverse judgments could result in a decision by the affected participating manufacturers to substantially increase cigarette prices, thereby reducing cigarette consumption beyond the forecasts under the MSA. In addition, the financial condition of any or all of the participating manufacturer defendants could be materially and adversely affected by the ultimate outcome of pending litigation, including bonding and litigation costs or a verdict or verdicts awarding substantial compensatory or punitive damages. Depending upon the magnitude of any such negative financial impact (and irrespective of whether the participating manufacturer is thereby rendered insolvent), an adverse outcome in one or more of the lawsuits could substantially impair the affected participating manufacturer's ability to make payments under the MSA.

Credit Ratings of Municipal Securities. Ratings by ratings organizations such as Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Services ("S&P"), and Fitch, Inc. ("Fitch") represent the respective rating agency's opinions of the credit quality of the municipal securities they undertake to rate. However, their ratings are general opinions and are not guarantees of quality. Municipal securities that have the same maturity, coupon and rating may have different yields, while other municipal securities that have the same maturity and coupon but different ratings may have the same yield.

Below-investment-grade securities (also referred to as "junk bonds") may have a higher yield than securities rated in the higher rating categories. In addition to having a greater risk of default than higher-grade securities, there may be less of a market for these securities. As a result they may be harder to sell at an acceptable price. The additional risks mean that the Fund may not receive the anticipated level of income from these securities, and the Fund's net asset value may be affected by declines in the value of lower-grade securities.

After the Fund buys a municipal security, the security may cease to be rated or its rating may be reduced. Neither event requires the Fund to sell the security, but the Manager will consider such events in determining whether the Fund should continue to hold the security. To the extent that ratings given by Moody's, S&P, or Fitch change as a result of changes in those rating organizations or their rating systems, the Fund will attempt to use similar ratings as standards for investments in accordance with the Fund's investment policies.

The Fund may buy municipal securities that are "pre-refunded." The issuer's obligation to repay the principal value of the security is generally collateralized with U.S. Government securities placed in an escrow account. This causes the pre-refunded security to have essentially the same risks of default as a AAA-rated security.

A list of the rating categories of Moody's, S&P and Fitch for municipal securities is contained in an Appendix to this SAI. Because the Fund may purchase securities that are unrated by nationally recognized rating organizations, the Manager will make its own assessment of the credit quality of those unrated issues. The Manager will use criteria similar to those used by the rating agencies and assign a rating category to a security that is similar to what the Manager believes a rating agency would assign to that security. However, the Manager's rating does not constitute a guarantee of the quality of a particular issue.

In evaluating the credit quality of a particular security, whether it is rated or unrated, the Manager will normally take into consideration a number of factors. Among them are the financial resources of the issuer, or the underlying source of funds for debt service on a security, the issuer's sensitivity to economic conditions and trends, any operating history of the facility financed by the obligation and the degree of community support for it, the capabilities of the issuer's management and regulatory factors affecting the issuer and particular facility.

Special Risks of Below-Investment-Grade Securities. The Fund may invest in municipal securities rated below-investment-grade up to the limits described in the Prospectus. Lower-grade securities may have a higher yield than securities rated in the higher rating categories. In addition to having a greater risk of default than higher-grade securities, there may be less of a market for these securities. As a result they may be harder to sell at an acceptable price. The additional risks mean that the Fund may not receive the anticipated level of income from these securities, and the Fund's net asset value may be affected by declines in the value of lower-grade securities.

While securities rated "Baa" by Moody's or "BBB" by S&P are investment grade, they may be subject to special risks and have some speculative characteristics.

U.S. Territories, Commonwealths and Possessions. The Fund also invests in municipal securities issued by certain territories, commonwealths and possessions of the United States that pay interest that is exempt (in the opinion of the issuer's legal counsel when the security is issued) from federal and state income tax. Therefore, the Fund's investments could be affected by the fiscal stability of, for example, Puerto Rico, the Virgin Islands, Guam, or the Northern Mariana Islands. Additionally, the Fund's investments could be affected by economic, legislative, regulatory or political developments affecting issuers in those territories, commonwealths or possessions. A discussion of the special considerations relating to the Fund's municipal obligations and other factors or economic conditions in those territories, commonwealths or possessions is provided in an Appendix to this SAI.

A discussion of the special considerations relating to the Fund's state municipal obligations and other factors or economic conditions in those territories, commonwealths or possessions is provided in Appendix B to this SAI.

Inverse Floaters. The Fund invests in "inverse floaters" which are derivative instruments that pay interest at rates that move in the opposite direction of yields on short term securities. As short term interest rates rise, the interest rate on inverse floaters falls and they produce less current income. As short term interest rates fall, the interest rates on the inverse floaters increase and they pay more current income. Their market value can be more volatile than that of a conventional fixed rate security having similar credit quality, redemption provisions and maturity. The Fund can expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters.

An inverse floater is typically created by a trust that divides a municipal security into two securities: a short term tax-free floating rate security (sometimes referred to as a "tender option bond") and a long-term tax-exempt floating rate security (referred to as a residual certificate" or "inverse floater") that pays interest at rates that move in the opposite direction of the yield on the short term floating rate security. The purchaser of a "tender option bond" has the right to tender the security periodically for repayment of the principal value. As short-term interest rates rise, inverse floaters produce less current income (and, in extreme cases, may pay no income) and as short-term interest rates fall, inverse floaters produce more current income.

To facilitate the creation of inverse floaters, the Fund may purchase a municipal security and subsequently transfer it to a broker-dealer (the sponsor), which deposits the municipal security in a trust. The trust issues the residual certificates and short-term floating rate securities. The trust documents enable the Fund to withdraw the underlying bond to unwind or "collapse" the trust (upon tendering the residual certificate and paying the value of the short-term bonds and certain other costs). The Fund may also purchase inverse floaters created by municipal issuers directly or by other parties that have deposited municipal bonds into a sponsored trust.

The Fund may also purchase inverse floaters created when another party transfers a municipal security to a trust. The trust then issues short term floating rate notes to third parties and sells the inverse floater to the Fund. Under some circumstances, the Manager might acquire both portions of that type of offering, to reduce the effect of the volatility of the individual securities. This provides the Manager with a flexible portfolio management tool to vary the degree of investment leverage efficiently under different market conditions.

Additionally, the Fund may be able to purchase inverse floaters created by municipal issuers directly. To provide investment leverage, a municipal issuer might issue two variable rate obligations instead of a single long-term, fixed-rate security. For example, the interest rate on one obligation reflecting short term interest rates and the interest rate on the other instrument, the inverse floater, reflecting the approximate rate the issuer would have paid on a fixed rate security, multiplied by a factor of two, minus the rate paid on the short term instrument.

Inverse floaters may offer relatively high current income, reflecting the spread between long term and short term tax-exempt interest rates. As long as the municipal yield curve remains positively sloped, and short term rates remain low relative to long term rates, owners of inverse floaters will have the opportunity to earn interest at above market rates. If the yield curve flattens and shifts upward, an inverse floater will lose value more quickly than a conventional long term security having similar credit quality, redemption provisions and maturity.

Some inverse floaters have a feature known as an interest rate "cap" as part of the terms of the investment. Investing in inverse floaters that have interest rate caps might be part of a portfolio strategy to try to maintain a high current yield for the Fund when the Fund has invested in inverse floaters that expose the Fund to the risk of short term interest rate fluctuations. "Embedded" caps can be used to hedge a portion of the Fund's exposure to rising interest rates. When interest rates exceed a pre-determined rate, the cap generates additional cash flows that offset the decline in interest rates on the inverse floater. However, the Fund bears the risk that if interest rates do not rise above the pre-determined rate, the cap (which is purchased for additional cost) will not provide additional cash flows and will expire worthless.

The Fund may enter into a "shortfall and forbearance" agreement with the sponsor of an inverse floater held by the Fund. Under such an agreement, on liquidation of the trust, the Fund would be committed to pay the trust the difference between the liquidation value of the underlying security on which the inverse floater is based and the principal amount payable to the holders of the short-term floating rate security that is based on the same underlying security. The Fund would not be required to make such a payment under the standard terms of a more typical inverse floater. Although entering into a "shortfall and forbearance" agreement would expose the Fund to the risk that it may be required to make the payment described above, the Fund may receive higher interest payments than under a typical inverse floater.

An investment in inverse floaters may involve greater risk than an investment in a fixed rate municipal security. All inverse floaters entail some degree of leverage. The interest rate on inverse floaters varies inversely at a pre-set multiple of the change in short term rates. An inverse floater that has a higher multiple, and therefore more leverage, will be more volatile with respect to both price and income than an inverse floater with a lower degree of leverage or than the underlying security.

Because of the accounting treatment for inverse floaters created by the Fund's transfer of a municipal bond to a trust, the Fund's financial statements will reflect these transactions as "secured borrowings," which affects the Fund's expense ratios, statements of income and assets and liabilities and causes the Fund's Statement of Investments to include the underlying municipal bond.

Floating Rate and Variable Rate Obligations. Floating or variable rate obligations may have a demand feature that allows the Fund to tender the obligation to the issuer or a third party prior to its maturity. The tender may be at par value plus accrued interest, according to the terms of the obligations.

The interest rate on a floating rate demand note is based on a market rate, such as the percentage of LIBOR, the SIFMA Municipal Swap index or a bank's prime rate and is adjusted automatically each time such rate is adjusted. The interest rate on a variable rate demand note is also based on a specified market rate but is adjusted automatically at specified intervals of not less than one year. Generally, the changes in the interest rates on such securities reduce the fluctuation in their market value. As interest rates decrease or increase, the potential for capital appreciation or depreciation is less than that for fixed-rate obligations of the same maturity. The Manager may determine that an unrated floating rate or variable rate demand obligation meets the Fund's quality standards by reason of being backed by a letter of credit or guarantee issued by a bank that meets those quality standards.

Floating rate and variable rate demand notes that have a stated maturity in excess of one year may have features that permit the holder to recover the principal amount of the underlying security at specified intervals not exceeding one year and upon no more than 30 days' notice. The issuer of that type of note normally has a corresponding right in its discretion, after a given period, to prepay the outstanding principal amount of the note plus accrued interest. Generally the issuer must provide a specified number of days' notice to the holder. Floating rate or variable rate obligations that do not provide for the recovery of principal and interest within seven days are subject to the Fund's limitations on investments in illiquid securities.

Other Investments and Investment Strategies

The Fund may also use the following types of investments and investment strategies.

Percentage of LIBOR Notes (PLNs). The Fund may invest in Percentage of LIBOR Notes ("PLNs") which are variable rate municipal securities based on the London Interbank Offered Rate ("LIBOR"), a widely used benchmark for short-term interest rates and used by banks for interbank loans with other banks. The PLN typically pays interest based on a percentage of a LIBOR rate for a specified time plus an established yield premium. Due to their variable rate features, PLNs will generally pay higher levels of income in a rising short-term interest rate environment and lower levels of income as short-term interest rates decline. In times of substantial market volatility, however, the PLNs may not perform as anticipated. The value of a PLN also may decline due to other factors, such as changes in credit quality of the underlying bond.

The Fund also may invest in PLNs that are created when a broker-dealer/sponsor deposits a municipal bond into a trust created by the sponsor. The trust issues a percentage of LIBOR floating rate certificate (i.e., the PLN) to the Fund and a residual interest certificate to third parties who receive the remaining interest on the bond after payment of the interest distribution to the PLN holder and other fees.

Because the market for PLNs is relatively new and still developing, the Fund's ability to engage in transactions using such instruments may be limited. There is no assurance that a liquid secondary market will exist for any particular PLN or at any particular time, and so the Fund may not be able to close a position in a PLN when it is advantageous to do so.

When-Issued and Delayed-Delivery Transactions. The Fund can purchase securities on a "when-issued" basis, and may purchase or sell such securities on a "delayed-delivery" basis. "When-issued" or "delayed-delivery" refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. 

When such transactions are negotiated, the price (which is generally expressed in yield terms) is fixed at the time the commitment is made. Delivery and payment for the securities take place at a later date. Normally the settlement date is within six months of the purchase of municipal bonds and notes. However, the Fund may, from time to time, purchase municipal securities having a settlement date more than six months and possibly as long as two years or more after the trade date. The securities are subject to change in value from market fluctuation during the settlement period. The value at delivery may be less than the purchase price. For example, changes in interest rates in a direction other than that expected by the Manager before settlement will affect the value of such securities and may cause loss to the Fund. No income begins to accrue to the Fund on a when-issued security until the Fund receives the security at settlement of the trade. 

The Fund will engage in when-issued transactions in order to secure what is considered to be an advantageous price and yield at the time of entering into the obligation. When the Fund engages in when-issued or delayed-delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain the security at a price and yield it considers advantageous. 

When the Fund engages in when-issued and delayed-delivery transactions, it does so for the purpose of acquiring or selling securities consistent with its investment objective and policies for its portfolio or for delivery pursuant to options contracts it has entered into, and not for the purposes of investment leverage. Although the Fund will enter into when-issued or delayed-delivery purchase transactions to acquire securities, the Fund may dispose of a commitment prior to settlement. If the Fund chooses to dispose of the right to acquire a when-issued security prior to its acquisition or to dispose of its right to deliver or receive against a forward commitment, it may incur a gain or loss. 

At the time the Fund makes a commitment to purchase or sell a security on a when-issued or forward commitment basis, it records the transaction on its books and reflects the value of the security purchased. In a sale transaction, it records the proceeds to be received, in determining its net asset value. In a purchase transaction the Fund will identify on its books liquid securities of any type with a value at least equal to the purchase commitments until the Fund pays for the investment. 

When-issued transactions and forward commitments can be used by the Fund as a defensive technique to hedge against anticipated changes in interest rates and prices. For instance, in periods of rising interest rates and falling prices, the Fund might sell securities in its portfolio on a forward commitment basis to attempt to limit its exposure to anticipated falling prices. In periods of falling interest rates and rising prices, the Fund might sell portfolio securities and purchase the same or similar securities on a when-issued or forward commitment basis, to obtain the benefit of currently higher cash yields.

Zero-Coupon Securities. The Fund may buy zero-coupon and delayed interest municipal securities. Zero-coupon securities do not make periodic interest payments and are sold at a deep discount from their face value. The buyer recognizes a rate of return determined by the gradual appreciation of the security, which is redeemed at face value on a specified maturity date. This discount depends on the time remaining until maturity, as well as prevailing interest rates, the liquidity of the security and the credit quality of the issuer. In the absence of threats to the issuer's credit quality, the discount typically decreases as the maturity date approaches. Some zero-coupon securities are convertible, in that they are zero-coupon securities until a predetermined date, at which time they convert to a security with a specified coupon rate.

Because zero-coupon securities pay no interest and compound semi-annually at the rate fixed at the time of their issuance, their value is generally more volatile than the value of other debt securities. Their value may fall more dramatically than the value of interest-bearing securities when interest rates rise. When prevailing interest rates fall, zero-coupon securities tend to rise more rapidly in value because they have a fixed rate of return.

The Fund's investment in zero-coupon securities may cause the Fund to recognize income and be required to make distributions to shareholders before it receives any cash payments on the zero-coupon investment. To generate cash to satisfy those distribution requirements, the Fund may have to sell portfolio securities that it otherwise might have continued to hold or to use cash flows from other sources such as the sale of Fund shares.

Puts and Standby Commitments. The Fund may acquire "stand-by commitments" or "puts" with respect to municipal securities to enhance portfolio liquidity and to try to reduce the average effective portfolio maturity. These arrangements give the Fund the right to sell the securities at a set price on demand to the issuing broker-dealer or bank. However, securities having this feature may have a relatively lower interest rate.

When the Fund buys a municipal security subject to a standby commitment to repurchase the security, the Fund is entitled to same-day settlement from the purchaser. The Fund receives an exercise price equal to the amortized cost of the underlying security plus any accrued interest at the time of exercise. A put purchased in conjunction with a municipal security enables the Fund to sell the underlying security within a specified period of time at a fixed exercise price.

The Fund might purchase a standby commitment or put separately in cash or it might acquire the security subject to the standby commitment or put (at a price that reflects that additional feature). The Fund will enter into these transactions only with banks and securities dealers that, in the Manager's opinion, present minimal credit risks. The Fund's ability to exercise a put or standby commitment will depend on the ability of the bank or dealer to pay for the securities if the put or standby commitment is exercised. If the bank or dealer should default on its obligation, the Fund might not be able to recover all or a portion of any loss sustained from having to sell the security elsewhere.

Puts and standby commitments are not transferable by the Fund. They terminate if the Fund sells the underlying security to a third party. The Fund intends to enter into these arrangements to facilitate portfolio liquidity, although such arrangements might enable the Fund to sell a security at a pre-arranged price that may be higher than the prevailing market price at the time the put or standby commitment is exercised. However, the Fund might refrain from exercising a put or standby commitment if the exercise price is significantly higher than the prevailing market price, to avoid imposing a loss on the seller that could jeopardize the Fund's business relationships with the seller.

A put or standby commitment increases the cost of the security and reduces the yield otherwise available from the security. Any consideration paid by the Fund for the put or standby commitment will be reflected on the Fund's books as unrealized depreciation while the put or standby commitment is held, and a realized gain or loss when the put or commitment is exercised or expires. Interest income received by the Fund from municipal securities subject to puts or stand-by commitments may not qualify as tax-exempt in its hands if the terms of the put or stand-by commitment cause the Fund not to be treated as the tax owner of the underlying municipal securities.

Repurchase Agreements. The Fund may acquire securities subject to repurchase agreements. Repurchase agreements may be acquired for temporary defensive purposes, to maintain liquidity to meet anticipated share redemptions, pending the investment of the proceeds from sales of shares, or pending the settlement of portfolio securities transactions. In a repurchase transaction, the purchaser buys a security from, and simultaneously resells it to, an approved vendor for delivery on an agreed-upon future date. The resale price exceeds the purchase price by an amount that reflects an agreed-upon interest rate effective for the period during which the repurchase agreement is in effect. Approved vendors include U.S. commercial banks, U.S. branches of foreign banks, or broker-dealers that have been designated as primary dealers in government securities. Vendors must meet credit requirements set by the Manager from time to time.

The majority of repurchase transactions run from day-to-day and delivery pursuant to the resale typically occurs within one to five days of the purchase. Repurchase agreements that have a maturity beyond seven days are subject to limits on illiquid investments. There is no limit on the amount of assets that may be subject to repurchase agreements having maturities of seven days or less. 

Repurchase agreements are considered "loans" under the Investment Company Act and are collateralized by the underlying security. Repurchase agreements require that at all times while the repurchase agreement is in effect, the value of the collateral must equal or exceed the repurchase price to fully collateralize the repayment obligation. However, if the vendor fails to pay the repurchase price on the delivery date, there may be costs incurred in disposing of the collateral and losses if there is a delay in the ability to do so. The Manager will monitor the vendor's creditworthiness to confirm that the vendor is financially sound and will continuously monitor the collateral's value.

Pursuant to an Exemptive Order issued by the Securities and Exchange Commission (the "SEC"), the Fund, along with the affiliated entities managed by the Manager, may transfer uninvested cash balances into one or more joint repurchase agreement accounts. These balances are invested in one or more repurchase agreements secured by U.S. Government securities. Securities that are pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each joint repurchase arrangement requires that the market value of the collateral be sufficient to cover payments of interest and principal; however, in the event of default by the other party to the agreement, retention or sale of the collateral may be subject to legal proceedings.

Reverse Repurchase Agreements. The Fund may engage in reverse repurchase agreements.  A reverse repurchase agreement is the sale of an underlying debt obligation and the simultaneous agreement to repurchase it at an agreed-upon price and date. These transactions involve the risk that the market value of the securities sold under a reverse repurchase agreement could decline below the cost of the obligation to repurchase them. The Fund will identify liquid assets on its books to cover its obligations under reverse repurchase agreements, including interest, until payment is made to the seller. These agreements are considered borrowings and are subject to the asset coverage requirement under policies on borrowing.

Borrowing and Leverage. The Fund can borrow from banks for investment-related purposes such as purchasing securities believed to be desirable by the Manager when available, funding amounts necessary to unwind or "collapse" trusts that issued "inverse floaters" to the Fund, or to contribute to such trusts to enable them to make tenders of their other securities by the holders. The Fund also can borrow from banks and other lenders to meet redemption obligations or for temporary and emergency purposes. When the Fund invests borrowed funds in portfolio securities, it is using a speculative investment technique known as "leverage." Under the Fund's investment policies, the Fund may not borrow money, except to the extent permitted under the Investment Company Act, the rules or regulations thereunder or any exemption from the Act that applies to the Fund. Currently, under the Investment Company Act, a mutual fund may borrow only from banks (for other than emergency purposes) and the maximum amount it may borrow is up to one-third of its total assets (including the amount borrowed) less all liabilities and indebtedness other than borrowings. When the Fund borrows, it earmarks securities on its books in an amount equal to 300% of the amount borrowed to cover its obligation to repay the loan. If the value of the Fund's assets fails to meet this 300% asset coverage requirement, the Fund will reduce its bank debt within three days to meet the requirement. To do so, the Fund might have to sell a portion of its investments at a disadvantageous time.

The Fund may also borrow up to 5% of its total assets for temporary or emergency purposes from any lender. Under the Investment Company Act, there is a rebuttable presumption that a loan is temporary if it is repaid within 60 days and not extended or renewed.

The Fund will pay interest on loans, and that interest expense will raise the overall expenses of the Fund and reduce its returns. If the Fund does borrow, its expenses will be greater than comparable funds that do not borrow. In the case of borrowing for leverage, the interest paid on a loan might be more (or less) than the yield on the securities purchased with the loan proceeds. Additionally, borrowing might cause the Fund's net asset value per share to fluctuate more than that of funds that do not borrow.

The Fund participates in a secured line of credit (the "Line of Credit") with certain conduit facilities, Citibank, N.A., and other banks. The Line of Credit enables the Fund to participate with certain other Oppenheimer funds in a committed, secured borrowing facility which permits borrowings of up to $2,250,000,000, in the aggregate by the participants. The Line of Credit is required to be operated in compliance with the terms of an exemptive order issued by the SEC to Citicorp North America, Inc. ("Citicorp"), which acts as agent for the lenders under the Line of Credit. That Line of Credit can be used to purchase securities for investment or for other business purposes. The Fund's Board determined that the Fund's participation in the Line of Credit is consistent with the Fund's investment objective and policies and is in the best interests of the Fund and its shareholders. To facilitate the lender's willingness to increase the amount available to the Fund and other affiliated funds that are borrowers under that loan facility, the Manager has used its own resources to fund certain collateral accounts for the potential benefit of one of the lenders, Citibank in connection with another investment program unrelated to the Fund or the loan. The Manager has received no compensation from the Fund or the lender for establishing that collateral account or in connection with the increase in the Line of Credit available to the Fund and its affiliated funds.

Loans are typically secured by assets of the Fund. Liquidity support for loans from the Line of Credit facility is provided by banks obligated to make loans to the Fund in the event the conduit or conduits are unable or unwilling to make such loans. Interest is charged to the Fund, based on its borrowings, at current commercial rates. The Fund has paid its pro rata portion of a loan commitment fee for the Line of Credit and the recent increase thereto, and pays additional fees annually to the lender on its outstanding borrowings to manage and administer the facility. The Fund can prepay such loans and terminate its participation in the Line of Credit at any time upon prior notice. As a borrower under the Line of Credit, the Fund has certain rights and remedies under state and federal law comparable to those it would have with respect to a loan from a bank.

Illiquid and Restricted Securities. Generally, an illiquid asset is an asset that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the price at which it has been valued. Under the policies and procedures established by the Board, the Manager determines the liquidity of portfolio investments. The Manager monitors holdings of illiquid and restricted securities on an ongoing basis to determine whether to sell any holdings to maintain adequate liquidity. Among the types of illiquid securities are repurchase agreements maturing in more than seven days.

Restricted securities acquired through private placements have contractual restrictions on their public resale that might limit the ability to value or to dispose of the securities and might lower the price that could be realized on a sale. To sell a restricted security that is not registered under applicable securities laws, the securities might need to be registered. The expense of registering restricted securities may be negotiated with the issuer at the time of purchase. If the securities must be registered in order to be sold, a significant period may elapse between the time the decision is made to sell the security and the time the security is registered. There is a risk of downward price fluctuation during that period.

Limitations that apply to purchases of restricted securities do not limit purchases of restricted securities that are eligible for sale to qualified institutional buyers under Rule 144A of the Securities Act of 1933, if those securities have been determined to be liquid by the Manager under Board-approved guidelines. Those guidelines take into account the trading activity for the securities and the availability of reliable pricing information, among other factors. If there is a lack of trading interest in a particular Rule 144A security, holdings of that security may be considered to be illiquid.

Loans of Portfolio Securities. Securities lending pursuant to a Securities Lending Agency Agreement (the "Securities Lending Agreement") with Goldman Sachs Bank USA, doing business as Goldman Sachs Agency Lending ("Goldman Sachs"), may be used to attempt to increase income. Loans of portfolio securities are subject to the restrictions stated in the Prospectus and must comply with all applicable regulations and with the Fund's Securities Lending Procedures adopted by the Board. The terms of any loans must also meet applicable tests under the Internal Revenue Code.

There are certain risks in connection with securities lending, including possible delays in receiving additional collateral to secure a loan, or a delay or expenses in recovery of the loaned securities. Goldman Sachs has agreed, in general, to guarantee the obligations of borrowers to return loaned securities and to be responsible for certain expenses relating to securities lending. Under the Securities Lending Agreement, the Fund's securities lending procedures and applicable regulatory requirements (which are subject to change), the Fund must receive collateral from the borrower consisting of cash, bank letters of credit or securities of the U.S. Government (or its agencies or instrumentalities). On each business day, the amount of collateral that the Fund has received must at least equal the value of the loaned securities. If the Fund receives cash collateral from the borrower, the Manager, in its capacity as the Fund's collateral administrator, may invest that cash in certain high quality, short-term investments, including in money market funds advised by the Manager. The Fund will be subject to its proportional share of the expenses of such money market funds, including the advisory fee payable to the Manager or its affiliate as adviser to such funds. The Manager may charge a collateral administration fee of 0.08% on the value of cash collateral invested in other securities. All of the Fund's collateral investments must comply with its securities lending procedures. The Fund will be responsible for the risks associated with the investment of cash collateral, including the risk that the Fund may lose money on the investment or may fail to earn sufficient income to meet its obligations to the borrower.

The terms of the loans must permit the Fund to recall loaned securities on five business days' notice and the Fund will seek to recall loaned securities in time to vote on any matters that the Manager determines would have a material effect on the Fund's investment. The Securities Lending Agreement may be terminated by either Goldman Sachs or the Fund on 30 days' written notice.

Loans of portfolio securities are limited to not more than 25% of the value of the Fund's net assets.

Liquidity Facility. The Fund can participate in a program offered by ReFlow, LLC ("ReFlow") which provides additional liquidity to help the Fund meet shareholder redemptions without having to liquidate portfolio securities or borrow money, each of which imposes certain costs on the Fund. ReFlow is designed to provide an alternative source of funding to help meet shareholder redemptions while minimizing the Fund's costs and cash flow disruptions (compared to selling portfolio securities or other liquidity facilities such as a line of credit) and allowing the Fund to remain more fully invested. ReFlow provides this liquidity by being prepared to purchase Fund shares, at the Fund's closing net asset value, equal to the amount of the Fund's net redemptions on any given day. On subsequent days when the Fund experiences net subscriptions, ReFlow redeems its holdings at the Fund's net asset value on that day. When the Fund participates in the ReFlow program, it pays ReFlow a fee at a rate determined by a daily auction with other participating mutual funds in the ReFlow program. There is no assurance that ReFlow will have sufficient funds available to meet the Fund's liquidity needs on a particular day and ReFlow is prohibited from acquiring more than 3% of the outstanding shares of the Fund.

Other Derivative Investments. Certain derivatives, such as options, futures, indexed securities and entering into swap agreements, can be used to increase or decrease the Fund's exposure to changing security prices, interest rates or other factors that affect the value of securities. However, these techniques could result in losses to the Funds if the Manager judges market conditions incorrectly or employs a strategy that does not correlate well with the Fund's other investments. These techniques can cause losses if the counterparty does not perform its promises. An additional risk of investing in municipal securities that are derivative investments is that their market value could be expected to vary to a much greater extent than the market value of municipal securities that are not derivative investments but have similar credit quality, redemption provisions and maturities.

Hedging. The Fund may use hedging to attempt to protect against declines in the market value of its portfolio, to permit the Funds to retain unrealized gains in the value of portfolio securities that have appreciated, or to facilitate selling securities for investment reasons. To do so, the Fund may:

• sell interest rate futures or municipal bond index futures,

• buy puts on such futures or securities, or

• write covered calls on securities, broadly-based municipal bond indices, interest rate futures or municipal bond index futures.

Covered calls may also be written on debt securities to attempt to increase the Fund's income, but that income would not be tax-exempt. Therefore it is unlikely that the Fund would write covered calls for that purpose.

The Fund may also use hedging to establish a position in the debt securities market as a temporary substitute for purchasing individual debt securities. In that case the Fund will normally seek to purchase the securities, and then terminate that hedging position. For this type of hedging, the Fund may:

• buy interest rate futures or municipal bond index futures, or

• buy calls on such futures or on securities.

The Fund is not obligated to use hedging instruments, even though it is permitted to use them in the Manager's discretion, as described below. The Fund's strategy of hedging with futures and options on futures will be incidental to the Fund's investment activities in the underlying cash market. The particular hedging instruments the Fund can use are described below. The Fund may employ new hedging instruments and strategies when they are developed, if those investment methods are consistent with the Fund's investment objective and are permissible under applicable regulations governing the Fund.

Futures. The Fund may buy and sell futures contracts relating to debt securities (these are called "interest rate futures"), and municipal bond indices (these are referred to as "municipal bond index futures").

An interest rate future obligates the seller to deliver (and the purchaser to take) cash or a specific type of debt security to settle the futures transaction. Either party could also enter into an offsetting contract to close out the futures position.

A "municipal bond index" assigns relative values to the municipal bonds in the index, and is used as the basis for trading long-term municipal bond futures contracts. Municipal bond index futures are similar to interest rate futures except that settlement is made only in cash. The obligation under the contract may also be satisfied by entering into an offsetting contract. The strategies which the Fund employs in using municipal bond index futures are similar to those with regard to interest rate futures.

No money is paid by or received by the Fund on the purchase or sale of a futures contract. Upon entering into a futures transaction, the Fund will be required to deposit an initial margin payment in cash or U.S. Government securities with the futures commission merchant (the "futures broker"). Initial margin payments will be deposited with the Fund's custodian bank in an account registered in the futures broker's name. However, the futures broker can gain access to that account only under certain specified conditions. As the future is marked to market (that is, its value on the Fund's books is changed) to reflect changes in its market value, subsequent margin payments, called variation margin, will be paid to or by the futures broker daily.

At any time prior to the expiration of the future, the Fund may elect to close out its position by taking an opposite position at which time a final determination of variation margin is made and additional cash is required to be paid by or released to the Fund. Any gain or loss is then realized by the Fund on the future for tax purposes. Although interest rate futures by their terms call for settlement by the delivery of debt securities, in most cases the obligation is fulfilled without such delivery by entering into an offsetting transaction. All futures transactions are effected through a clearing house associated with the exchange on which the contracts are traded.

The Fund may concurrently buy and sell futures contracts in a strategy anticipating that the future the Fund purchased will perform better than the future the Fund sold. For example, the Fund might buy municipal bond futures and concurrently sell U.S. Treasury Bond futures (a type of interest rate future). The Fund would benefit if municipal bonds outperform U.S. Treasury Bonds on a duration-adjusted basis.

Duration is a volatility measure that refers to the expected percentage change in the value of a bond resulting from a change in general interest rates (measured by each 1% change in the rates on U.S. Treasury securities). For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the value of the bond to decline about 3%. There are risks that this type of futures strategy will not be successful. U.S. Treasury bonds might perform better on a duration-adjusted basis than municipal bonds, and the assumptions about duration that were used might be incorrect (in this case, the duration of municipal bonds relative to U.S. Treasury Bonds might have been greater than anticipated).

Put and Call Options.  Put options (sometimes referred to as "puts") give the holder the right to sell an asset for an agreed-upon price. Call options (sometimes referred to as "calls") give the holder the right to buy an asset at an agreed-upon price.

Writing Covered Call Options. The Fund may write (that is, sell) call options. The Fund's call writing is subject to a number of restrictions:

1. After the Fund writes a call, not more than 25% of the Fund's total assets may be subject to calls.
2. Calls the Fund sells must be listed on a securities or commodities exchange or quoted on NASDAQ®, the automated quotation system of The NASDAQ® Stock Market, Inc. or traded in the over-the-counter market.
3. Each call the Fund writes must be "covered" while it is outstanding. That means the Fund must own the investment on which the call was written.
4. The Fund may write calls on futures contracts whether or not it owns them.

When the Fund writes a call on a security, it receives cash (a premium). The Fund agrees to sell the underlying investment to a purchaser of a corresponding call on the same security during the call period at a fixed exercise price regardless of market price changes during the call period. The call period is usually not more than nine months. The exercise price may differ from the market price of the underlying security. The Fund has retained the risk of loss that the price of the underlying security may decline during the call period. That risk may be offset to some extent by the premium the Fund receives. If the value of the investment does not rise above the call price, it is likely that the call will lapse without being exercised. In that case the Fund would keep the cash premium and the investment. 

When the Fund writes a call on an index, it receives cash (a premium). If the buyer of the call exercises it, the Fund will pay an amount of cash equal to the difference between the closing price of the call and the exercise price, multiplied by the specified multiple that determines the total value of the call for each point of difference. If the value of the underlying investment does not rise above the call price, it is likely that the call will lapse without being exercised. In that case the Fund would keep the cash premium. 

The Fund's custodian bank, or a securities depository acting for the custodian bank, will act as the Fund's escrow agent through the facilities of the Options Clearing Corporation ("OCC"), as to the investments on which the Fund has written calls traded on exchanges, or as to other acceptable escrow securities. In that way, no margin will be required for such transactions. OCC will release the securities on the expiration of the calls or upon the Fund's entering into a closing purchase transaction. 

When the Fund writes an over-the-counter ("OTC") option, it will enter into an arrangement with a primary U.S. Government securities dealer which will establish a formula price at which the Fund will have the absolute right to repurchase that OTC option. The formula price would generally be based on a multiple of the premium received for the option, plus the amount by which the option is exercisable below the market price of the underlying security (that is, the option is "in-the-money"). When the Fund writes an OTC option, it will treat as illiquid (for purposes of its restriction on illiquid securities) the mark-to-market value of any OTC option held by it, unless the option is subject to a buy-back agreement by the executing broker. 

To terminate its obligation on a call it has written, the Fund may purchase a corresponding call in a "closing purchase transaction." The Fund will then realize a profit or loss, depending upon whether the net of the amount of the option transaction costs and the premium received on the call the Fund wrote was more or less than the price of the call the Fund purchased to close out the transaction. A profit may also be realized if the call lapses unexercised, because the Fund retains the underlying investment and the premium received. Any such profits are considered short-term capital gains for federal tax purposes, as are premiums on lapsed calls. When distributed by the Funds they are taxable as ordinary income.

Writing Uncovered Call Options on Futures Contracts. The Funds may also write calls on futures contracts without owning the futures contract or securities deliverable under the contract. To do so, at the time the call is written, the Fund must cover the call by segregating in escrow an equivalent dollar value of liquid assets. The Fund will segregate additional liquid assets if the value of the escrowed assets drops below 100% of the current value of the future. Because of this escrow requirement, in no circumstances would the Fund's receipt of an exercise notice as to that future put the Fund in a "short" futures position.

Purchasing Puts and Calls. The Fund may buy calls only on securities, broadly-based municipal bond indices, municipal bond index futures and interest rate futures. It may also buy calls to close out a call it has written, as discussed above. Calls the Fund buys must be listed on a securities or commodities exchange, or quoted on NASDAQ®, or traded in the over-the-counter market. A call or put option may not be purchased if the purchase would cause the value of all the Fund's put and call options to exceed 5% of its total assets. 

When the Fund purchases a call (other than in a closing purchase transaction), it pays a premium. For calls on securities that the Fund buys, it has the right to buy the underlying investment from a seller of a corresponding call on the same investment during the call period at a fixed exercise price. The Fund benefits only if (1) the call is sold at a profit or (2) the call is exercised when the market price of the underlying investment is above the sum of the exercise price plus the transaction costs and premium paid for the call. If the call is not exercised nor sold (whether or not at a profit), it will become worthless at its expiration date. In that case the Fund will lose its premium payment and the right to purchase the underlying investment. 

Calls on municipal bond indices, interest rate futures and municipal bond index futures are settled in cash rather than by delivering the underlying investment. Gain or loss depends on changes in the securities included in the index in question (and thus on price movements in the debt securities market generally) rather than on changes in price of the individual futures contract. 

The Fund may buy only those puts that relate to securities that it owns, broadly-based municipal bond indices, municipal bond index futures or interest rate futures (whether or not the Fund owns the futures). 

When the Fund purchases a put, it pays a premium. The Fund then has the right to sell the underlying investment to a seller of a corresponding put on the same investment during the put period at a fixed exercise price. Puts on municipal bond indices are settled in cash. Buying a put on a debt security, interest rate future or municipal bond index future the Fund owns enables it to protect itself during the put period against a decline in the value of the underlying investment below the exercise price. If the market price of the underlying investment is equal to or above the exercise price and as a result the put is not exercised or resold, the put will become worthless at its expiration date. In that case the Fund will lose its premium payment and the right to sell the underlying investment. A put may be sold prior to expiration (whether or not at a profit).

Risks of Hedging with Options and Futures. The use of hedging instruments requires special skills and knowledge of investment techniques that are different than those required for normal portfolio management. These risks of using options and futures include the following:

Selection Risk.  If the Manager uses an option at the wrong time or judges market conditions incorrectly, or if the prices of its options positions are not correlated with its other investments, a hedging strategy may reduce returns or cause losses. If a covered call option is sold on an investment that increases in value, if the call is exercised, no gain will be realized on the increase in the investment's value above the call price. A put option on a security that does not decline in value will cost the amount of the purchase price and without providing any benefit if it cannot be resold.

Liquidity Risk. Losses might also be realized if a position could not be closed out because of illiquidity in the market for an option. An option position may be closed out only on a market that provides secondary trading for options of the same series, and there is no assurance that a liquid secondary market will exist for any particular option.

Leverage Risk. Premiums paid for options are small compared to the market value of the underlying investments. Consequently, options may involve large amounts of leverage, which could result in the Fund's net asset value being more sensitive to changes in the value of the underlying investments.

Correlation Risk. If the Fund sells futures or purchases puts on broadly-based indices or futures to attempt to protect against declines in the value of its portfolio securities, it may be subject to the risk that the prices of the futures or the applicable index will not correlate with the prices of those portfolio securities. For example, the market or the index might rise but the value of the hedged portfolio securities might decline. In that case, the Fund would lose money on the hedging instruments and also experience a decline in the value of the portfolio securities. Over time, however, the value of a diversified portfolio of securities will tend to move in the same direction as the indices upon which related hedging instruments are based.

The risk of imperfect correlation increases as the composition of the portfolio diverges from the securities included in the applicable index. To compensate for the imperfect correlation of movements in the price of the portfolio securities being hedged and movements in the price of the hedging instruments, the Fund might use a greater dollar amount of hedging instruments than the dollar amount of portfolio securities being hedged, particularly if the historical price volatility of the portfolio securities being hedged is more than the historical volatility of the applicable index.

Transaction Costs. Option activities might also affect portfolio turnover rates and brokerage commissions. The portfolio turnover rate might increase if the Fund is required to sell portfolio securities that are subject to call options it has sold or if it exercises put options it has bought. Although the decision to exercise a put it holds is within the Fund's control, holding a put might create an additional reason to purchase a security. There may also be a brokerage commission on each purchase or sale of a put or call option. Those commissions may be higher on a relative basis than the commissions for direct purchases or sales of the underlying investments. A brokerage commission may also be paid for each purchase or sale of an underlying investment in connection with the exercise of a put or call.

Interest Rate Swaps. In an interest rate swap, the Fund and another party exchange their rights to receive interest payments on a security or other reference rate. For example, they might swap the right to receive floating rate payments for the right to receive fixed rate payments.

Interest rate swap agreements entail both interest rate risk and credit risk. There is a risk that based on movements of interest rates, the payments made by the Fund under a swap agreement will be greater than the payments it receives. Credit risk is the risk that the counterparty might default. If the counterparty defaults, the Fund may lose the net amount of contractual interest payments that it has not yet received.

The Fund can enter into swap transactions with certain counterparties pursuant to master netting agreements. A master netting agreement provides that all swaps done between the Fund and that counterparty shall be regarded as parts of an integral agreement. On any date, amounts payable in the same currency to or from the Fund in respect to one or more swap transactions will be combined and the Fund will receive or be obligated to pay the net amount.

The master netting agreement may also provide that if a counterparty defaults on one swap, the Fund can terminate all of the swaps with that counterparty. The gains and losses on all swaps are netted, and the result is the counterparty's gain or loss on termination. The termination of all swaps and the netting of gains and losses on termination are generally referred to as "aggregation."

The Fund may not enter into swaps with respect to more than 25% of its total assets.

Regulatory Aspects of Derivatives and Hedging Instruments. The Commodity Futures Trading Commission has eliminated limitations on futures trading by certain regulated entities, including registered investment companies. Consequently, registered investment companies may engage in unlimited futures transactions and options thereon by claiming an exclusion from regulation as a commodity pool operator under the Commodity Exchange Act.

Options transactions are subject to limitations established by the option exchanges. The exchanges limit the maximum number of options that may be written or held by a single investor or group of investors acting in concert. Those limits apply regardless of whether the options were purchased, sold or held through one or more different exchanges or are held in one or more accounts or through one or more brokers. Thus, the number of options that can be sold by an investment company advised by the Manager may be affected by options written or held by other investment companies advised by the Manager or affiliated entities. The exchanges also impose position limits on futures transactions. An exchange may order the liquidation of positions found to be in violation of those limits and may impose certain other sanctions.

Under SEC staff interpretations regarding applicable provisions of the Investment Company Act, when a registered investment company purchases a future, it must identify cash or other liquid assets at its custodian bank in an amount equal to the purchase price of the future, less the margin deposit applicable to it.

Temporary Defensive and Interim Investments. The securities the Fund may invest in for temporary defensive purposes include the following:

• short-term municipal securities;

• obligations issued or guaranteed by the U.S. Government or its agencies or instrumentalities;

• corporate debt securities rated within the three highest grades by a nationally recognized rating agency;

• commercial paper rated "A-1" by S&P, or a comparable rating by another nationally recognized rating agency; and

• certificates of deposit of domestic banks with assets of $1 billion or more.

The Fund also might hold these types of securities pending the investment of proceeds from the sale of portfolio securities or to meet anticipated redemptions of Fund shares. The income from some of the temporary defensive or interim investments may not be tax-exempt. Therefore, when making those investments, the Fund might not achieve its objective.

Taxable Investments. While the Fund can invest up to 20% of its net assets (plus borrowings for investment purposes) in investments that generate income subject to income taxes, it does not anticipate investing substantial amounts of its assets in taxable investments under normal market conditions or as part of its normal trading strategies and policies. Taxable investments include, for example, hedging instruments, repurchase agreements, and many of the types of securities the Fund would buy for temporary defensive purposes.

At times, in connection with the restructuring of a municipal bond issuer either outside of bankruptcy court in a negotiated workout or in the context of bankruptcy proceedings, the Fund may determine or be required to accept equity or taxable debt securities, or the underlying collateral (which may include real estate) from the issuer in exchange for all or a portion of the Fund's holdings in the municipal security. Although the Manager will attempt to sell those assets as soon as reasonably practicable in most cases, depending upon, among other things, the Manager's valuation of the potential value of such assets in relation to the price that could be obtained by the Fund at any given time upon sale thereof, the Fund may determine to hold such securities or assets in its portfolio for limited period of time in order to liquidate the assets in a manner that maximizes their value to the Fund.

Portfolio Turnover. A change in the securities held by the Fund from buying and selling investments is known as "portfolio turnover." Short-term trading increases the rate of portfolio turnover and could increase the Fund's transaction costs. However, the Fund ordinarily incurs little or no brokerage expense because most of the Fund's portfolio transactions are principal trades that do not require payment of brokerage commissions.

The Fund ordinarily does not trade securities to achieve short-term capital gains, because such gains would not be tax-exempt income. To a limited degree, the Fund may engage in active and frequent short-term trading to attempt to take advantage of short-term market variations. It may also do so to dispose of a portfolio security prior to its maturity. That might be done if, on the basis of a revised credit evaluation of the issuer or other considerations, the Manager believes such disposition is advisable or it needs to generate cash to satisfy requests to redeem Fund shares. In those cases, the Fund may realize a capital gain or loss on its investments. The Fund's annual portfolio turnover rate normally is not expected to exceed 100%. The Financial Highlights table at the end of the Prospectus shows the Fund's portfolio turnover rates during the past five fiscal years.

Investment Restrictions

Fundamental Policies. The Fund has adopted policies and restrictions to govern its investments. Under the Investment Company Act, fundamental policies are those policies that can be changed only by the vote of a "majority" of the Fund's outstanding voting securities, which is defined as the vote of the holders of the lesser of:

• 67% or more of the shares present or represented by proxy at a shareholder meeting, if the holders of more than 50% of the outstanding shares are present or represented by proxy; or

• more than 50% of the outstanding shares.

The Fund's investment objective is a fundamental policy. Other policies described in the Prospectus or this SAI are "fundamental" only if they are identified as such. The Fund's Board of Trustees can change non-fundamental policies without shareholder approval. However, significant changes to investment policies will be described in supplements or updates to the Prospectus or this SAI, as appropriate.  The Fund's most significant investment policies are described in the Prospectus.

Other Fundamental Investment Restrictions. The following investment restrictions are fundamental policies of the Fund.

• The Fund cannot make loans, except to the extent permitted under the Investment Company Act, the rules or regulations thereunder or any exemption therefrom that is applicable to the Fund, as such statute, rules or regulations may be amended or interpreted from time to time.

• The Fund may not borrow money, except to the extent permitted under the Investment Company Act, the rules or regulations thereunder or any exemption therefrom that is applicable to the Fund, as such statute, rules or regulations may be amended or interpreted from time to time.

• The Fund cannot invest more than 25% of its total assets in any one industry but can invest more than 25% of its total assets in a group of industries. That limit does not apply to securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities or securities issued by investment companies. Nor does that limit apply to municipal securities in general or to the Fund's respective State's municipal securities.

• The Fund cannot invest in real estate, physical commodities or commodity contracts, except to the extent permitted under the Investment Company Act, the rules or regulations thereunder or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

• The Fund may not underwrite securities issued by others, except to the extent that the Fund may be considered an underwriter within the meaning of the Securities Act of 1933, as amended, when reselling securities held in its own portfolio.

• The Fund cannot issue senior securities, except to the extent permitted under the Investment Company Act, the rules or regulations thereunder or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time.

Currently, under the Investment Company Act, and the Fund's exemptive order, a fund may borrow only from banks and/or affiliated investment companies in an amount up to one-third of its total assets (including the amount borrowed less all liabilities and indebtedness other than borrowing), except that a fund may borrow up to 5% of its total assets for temporary purposes from any person. Under the Investment Company Act, there is a rebuttable presumption that a loan is temporary if it is repaid within 60 days and not extended or renewed. Also, presently under the Investment Company Act, a fund may lend its portfolio securities in an amount not to exceed 33 1/3 percent of the value of its total assets.

Unless the Prospectus or this SAI states that a percentage restriction applies on an ongoing basis, it applies only at the time the Fund makes an investment. That means the Fund is not required to sell securities to meet the percentage limits if the value of the investment increases in proportion to the size of the Fund. Percentage limits on borrowing and investments in illiquid securities apply on an ongoing basis.

Investment in Debt Securities Secured by Real Estate. The Investment Company Act requires each registered fund to adopt a fundamental policy regarding investments in real estate and/or commodities. The Fund does not have any restrictions on investments in real estate and/or commodities other than the information set forth in the investment restrictions above. Although the Fund is not expected to invest in real estate, to the extent consistent with its investment objective and its policies, the Fund would be permitted to invest in debt securities secured by real estate or interests in real estate, or issued by companies, including real estate investment trusts, that invest in real estate or interests in real estate. It is possible that the Fund could, as a result of an investment in debt securities of an issuer, come to hold an interest in real estate if the issuer defaulted on its debt obligations.

Non-Diversification of the Fund's Investments. The Fund is "non-diversified" as defined in the Investment Company Act. Funds that are diversified have restrictions against investing too much of their assets in the securities of any one "issuer." That means that the Fund can invest more of its assets in the securities of a single issuer than a fund that is diversified.

Being non-diversified poses additional investment risks, because if the Fund invests more of its assets in fewer issuers, the value of its shares is subject to greater fluctuations from adverse conditions affecting any one of those issuers. However, the Fund does limit its investments in the securities of any one issuer to qualify for tax purposes as a "regulated investment company" under the Internal Revenue Code. If it qualifies, the Fund does not have to pay federal income taxes if more than 90% of its earnings are distributed to shareholders. To qualify, the Fund must meet a number of conditions. First, not more than 25% of the market value of the Fund's total assets may be invested in the securities of a single issuer (other than government securities and securities of other regulated investment companies), two or more issuers that are engaged in the same or related trades or businesses and are controlled by the Fund, or one or more qualified publicly traded partnerships (i.e., publicly-traded partnerships that are treated as partnerships for tax purposes and derive at least 90% of their income from certain passive sources). Second, with respect to 50% of the market value of its total assets, (1) no more than 5% of the market value of its total assets may be invested in the securities of a single issuer, and (2) the Fund must not own more than 10% of the outstanding voting securities of a single issuer.

The identification of the issuer of a municipal security depends on the terms and conditions of the security. When the assets and revenues of an agency, authority, instrumentality or other political subdivision are separate from those of the government creating it and the security is backed only by the assets and revenues of the subdivision, agency, authority or instrumentality, the latter would be deemed to be the sole issuer. Similarly, if an industrial development bond is backed only by the assets and revenues of the non-governmental user, then that user would be deemed to be the sole issuer. However, if in either case the creating government or some other entity guarantees a security, the guarantee would be considered a separate security and would be treated as an issue of such government or other entity.

Applying the Restriction Against Concentration. In implementing the Fund's policy not to concentrate its investments, the Manager will consider a non-governmental user of facilities financed by private activity bonds as being in a particular industry. That is done even though the bonds are municipal securities, as to which the Fund has no concentration limitation. The Manager categorizes tobacco industry related municipal bonds as either tobacco settlement revenue bonds or tobacco bonds that are subject to appropriation ("STA Bonds"). For purposes of the Funds' industry concentration policies, STA Bonds are considered to be "municipal" bonds, as distinguished from "tobacco" bonds. As municipal bonds, STA Bonds are not within any industry and are not subject to the Funds' industry concentration policies.

Other types of municipal securities that are not considered a part of any "industry" under the Fund's industry concentration policy include: general obligation, government appropriation, municipal leases, special assessment and special tax bonds. Although these types of municipal securities may be related to certain industries, because they are issued by governments or their political subdivisions rather than non-governmental users, these types of municipal securities are not considered a part of an industry for purposes of the Fund's industry concentration policy.

Therefore, the Fund may invest more than 25% of its total assets in these types of municipal securities, which may finance similar types of projects or from which the interest is paid from revenues of similar types of projects. "Similar types of projects" are projects that are related in such a way that economic, business or political developments tend to have the same impact on each similar project. For example, a change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining economic need for the project, would likely affect all similar projects, thereby increasing market risk. Thus, market changes that affect a security issued in connection with one project also would affect securities issued in connection with similar types of projects.

For purposes of the Fund's policy not to concentrate its investments as described above, the Fund has adopted classifications of industries and groups of related industries. These classifications are not fundamental polices.

Non-Fundamental Restrictions. The Fund has the following additional operating policies that are not "fundamental" and can be changed by the Board without shareholder approval.

• The Fund cannot invest in securities of other investment companies, except to the extent permitted under the Investment Company Act, the rules and regulations thereunder or any exemption therefrom, as such statute, rules and regulations may be amended or interpreted from time to time.

Disclosure of Portfolio Holdings

While recognizing the importance of providing Fund shareholders with information about their Fund's investments and providing portfolio information to a variety of third parties to assist with the management, distribution and administrative processes, the need for transparency must be balanced against the risk that third parties who gain access to the Fund's portfolio holdings information could attempt to use that information to trade ahead of or against the Fund, which could negatively affect the prices the Fund is able to obtain in portfolio transactions or the availability of the securities that a portfolio manager is trading on the Fund's behalf.

The Fund, the Manager, the Distributor and the Transfer Agent have therefore adopted policies and procedures regarding the dissemination of information about the Fund's portfolio holdings by employees, officers and directors or trustees of the Fund, the Manager, the Distributor and the Transfer Agent. These policies are designed to assure that non-public information about the Fund's portfolio securities holdings is distributed only for a legitimate business purpose, and is done in a manner that (a) conforms to applicable laws and regulations and (b) is designed to prevent that information from being used in a way that could negatively affect the Fund's investment program or enable third parties to use that information in a manner that is harmful to the Fund. It is a violation of the Code of Ethics for any covered person to release holdings in contravention of the portfolio holdings disclosure policies and procedures adopted by the Fund.

Portfolio Holdings Disclosure Policies. The Fund, the Manager, the Distributor and the Transfer Agent and their affiliates and subsidiaries, employees, officers, and directors or trustees, shall neither solicit nor accept any compensation or other consideration (including any agreement to maintain assets in the Fund or in other investment companies or accounts managed by the Manager or any affiliated person of the Manager) in connection with the disclosure of the Fund's non-public portfolio holdings. The receipt of investment advisory fees or other fees and compensation paid to the Manager and its subsidiaries pursuant to agreements approved by the Fund's Board shall not be deemed to be "compensation" or "consideration" for these purposes. Until publicly disclosed, the Fund's portfolio holdings are proprietary, confidential business information. After they are publicly disclosed, the Fund's portfolio holdings may be released in any appropriate manner.

• Public Disclosure. The Fund's portfolio holdings are made publicly available no later than 60 days after the close of each of the Fund's fiscal quarters, either in its annual or semi-annual report to shareholders or in its Statements of Investments on Form N-Q. Those documents are publicly available at the SEC. In addition, the top 20 month-end securities holdings (based on invested assets), listed by security or by issuer, may be posted on the OppenheimerFunds' website (at www.oppenheimerfunds.com) with a 15-day delay. The Fund may post a smaller list of holdings (e.g., the top five or top 10 portfolio holdings), or may not post any holdings, if the Manager believes that would be in the best interests of the Fund and its shareholders. Other general information about the Fund's portfolio investments, such as portfolio composition by asset class, industry, country, currency, credit rating or maturity, may also be publicly disclosed with a 15-day delay.

The Fund's complete portfolio holdings positions may be released to the following categories of individuals or entities on an ongoing basis, provided that such individual or entity either (1) has signed an agreement to keep such information confidential and not trade on the basis of such information, or (2) as a member of the Fund's Board, or as an employee, officer or director of the Manager, the Distributor, or the Transfer Agent, or of their legal counsel, is subject to fiduciary obligations (a) not to disclose such information except in compliance with the Fund's policies and procedures and (b) not to trade for his or her personal account on the basis of such information:

• Employees of the Fund's Manager, Distributor and Transfer Agent who need to have access to such information (as determined by senior officers of such entities);

• The Fund's independent registered public accounting firm;

• Members of the Fund's Board and the Board's legal counsel;

• The Fund's custodian bank;

• A proxy voting service designated by the Fund and its Board;

• Rating/ranking organizations (such as Lipper, Inc. and Morningstar, Inc.);

• Portfolio pricing services retained by the Manager to provide portfolio security prices; and

• Dealers, to obtain bids (price quotations if securities are not priced by the Fund's regular pricing services).

Month-end lists of the Fund's complete portfolio holdings may be disclosed for legitimate business reasons, no sooner than 30 days after the relevant month end, pursuant to special requests and under limited circumstances discussed below, provided that:

• The third-party recipient must first submit a request for release of Fund portfolio holdings, explaining the business reason for the request;

• Senior officers (a Senior Vice President, Deputy General Counsel or above) in the Manager's Portfolio and Legal departments must approve the completed request for release of Fund portfolio holdings; and

• Before receiving the data, the third-party recipient must sign the Manager's portfolio holdings non-disclosure agreement, agreeing to keep confidential the information that is not publicly available regarding the Fund's holdings and agreeing not to trade directly or indirectly based on the information.

Portfolio holdings information of the Fund may be provided, under limited circumstances, to brokers or dealers with whom the Fund trades and entities that provide investment coverage or analytical information regarding the Fund's portfolio, provided that there is a legitimate investment reason for providing the information to the broker, dealer or other entity. Month-end portfolio holdings information may, under this procedure, be provided to vendors providing research information or analytics to the Fund, with at least a 15-day delay after the month end, but in certain cases may be provided to a broker or analytical vendor with a 1- 2 day lag to facilitate the provision of requested investment information to the Manager to facilitate a particular trade or portfolio manager's investment process for the Fund. Any third party receiving such information must first sign the Manager's portfolio holdings non-disclosure agreement as a pre-condition to receiving this information.

Portfolio holdings information (which may include information on individual securities positions or multiple securities) may be provided to the entities listed below (1) by portfolio traders employed by the Manager in connection with portfolio trading, and (2) by the members of the Manager's Security Valuation Group and Accounting Departments in connection with portfolio pricing or other portfolio evaluation purposes:

• Brokers and dealers in connection with portfolio transactions (purchases and sales);

• Brokers and dealers to obtain bids or bid and asked prices (if securities held by the Fund are not priced by the fund's regular pricing services);

• Dealers to obtain price quotations where the fund is not identified as the owner.

Portfolio holdings information (which may include information on the Fund's entire portfolio or individual securities therein) may be provided by senior officers of the Manager or attorneys on the legal staff of the Manager, Distributor, or Transfer Agent, in the following circumstances:

• Response to legal process in litigation matters, such as responses to subpoenas or in class action matters where the Fund may be part of the plaintiff class (and seeks recovery for losses on a security) or a defendant;

• Response to regulatory requests for information (from the SEC, the Financial Industry Regulatory Authority ("FINRA"), state securities regulators, and/or foreign securities authorities, including without limitation requests for information in inspections or for position reporting purposes);

• To potential sub-advisers of portfolios (pursuant to confidentiality agreements);

• To consultants for retirement plans for plan sponsors/discussions at due diligence meetings (pursuant to confidentiality agreements);

• Investment bankers in connection with merger discussions (pursuant to confidentiality agreements).

Portfolio managers and analysts may, subject to the Manager's policies on communications with the press and other media, discuss portfolio information in interviews with members of the media, or in due diligence or similar meetings with clients or prospective purchasers of Fund shares or their financial representatives.

The Fund's shareholders may, under unusual circumstances (such as a lack of liquidity in the Fund's portfolio to meet redemptions), receive redemption proceeds of their Fund shares paid as pro rata shares of securities held in the Fund's portfolio. In such circumstances, disclosure of the Fund's portfolio holdings may be made to such shareholders.

Any permitted release of otherwise non-public portfolio holdings information must be in accordance with the then-current policy on approved methods for communicating confidential information.

The Chief Compliance Officer (the "CCO") of the Fund and the Manager, Distributor, and Transfer Agent shall oversee the compliance by the Manager, Distributor, Transfer Agent, and their personnel with these policies and procedures. The CCO reports to the Fund's Board any material violation of these policies and procedures during the previous calendar quarter and makes recommendations to the Board as to any amendments that the CCO believes are necessary and desirable to carry out or improve these policies and procedures.

The Manager and the Fund have entered into ongoing arrangements to make available information about the Fund's portfolio holdings. One or more of the Oppenheimer funds may currently disclose portfolio holdings information based on ongoing arrangements to the following parties:

How the Fund is Managed

Organization and History

Organization and History. The Fund is an open-end, non-diversified management investment company with an unlimited number of authorized shares of beneficial interest. The Fund was organized as a Massachusetts business trust in March 2006.

Classes of Shares. The Fund's Board of Trustees (the "Board") is authorized, without shareholder approval, to:

• create new series and classes of shares;

• reclassify unissued shares into additional series and classes; and

• divide or combine the shares of a class into a greater or lesser number of shares without changing the proportionate beneficial interest of a shareholder in the Fund.

The Fund currently has three classes of shares: Class A, Class B, and Class C. All classes invest in the same investment portfolio. Each class of shares:

• has its own dividends and distributions;

• pays certain expenses which may be different for the different classes;

• will generally have a different net asset value;

• will generally have separate voting rights on matters in which interests of one class are different from interests of another class; and

• votes as a class on matters that affect that class alone.

Each share of each class:

• represents an interest in the Fund proportionately equal to the interest of each other share of the same class;

• is freely transferable;

• has one vote at shareholder meetings, with fractional shares voting proportionally;

• may be voted in person or by proxy at shareholder meetings; and

• does not have cumulative voting rights, preemptive rights or subscription rights.

Board of Trustees and Oversight Committees

The Fund is governed by a Board of Trustees, which is responsible for protecting the interests of shareholders under Massachusetts and federal law. The Board is led by Brian F. Wruble, an independent trustee, who is not an "interested person" of the Fund, as that term is defined in the Investment Company Act of 1940. The Board meets periodically throughout the year to oversee the Fund's activities, review its performance, oversee the potential conflicts that could affect the Fund, and review the actions of the Manager. The Board has an Audit Committee, a Regulatory & Oversight Committee and a Governance Committee. Each Committee is comprised solely of Trustees who are not "interested persons" under the Investment Company Act (the "Independent Trustees"). Mr. Wruble's practice is to attend all meetings of each of the three Committees of the board where he participates in deliberation but does not have a vote.

During the Fund's fiscal year ended March 31, 2010, the Audit Committee held 4 meetings, the Regulatory & Oversight Committee held 5 meetings and the Governance Committee held 4 meetings.

The members of the Audit Committee are David K. Downes (Chairman), Phillip A. Griffiths, Mary F. Miller, Joseph M. Wikler and Peter I. Wold. The Audit Committee selects an independent registered public accounting firm (also referred to as the "independent Auditors"). Other main functions of the Audit Committee outlined in the Audit Committee Charter, include, but are not limited to: (i) reviewing the scope and results of financial statement audits and the audit fees charged; (ii) reviewing reports from the Fund's independent Auditors regarding the Fund's internal accounting procedures and controls; (iii) reviewing reports from the Manager's Internal Audit Department; (iv) maintaining a separate line of communication between the Fund's independent Auditors and the Independent Trustees/Directors; (v) reviewing the independence of the Fund's independent Auditors; and (vi) approving in advance the provision of any audit or non-audit services by the Fund's independent Auditors, including tax services, that are not prohibited by the Sarbanes-Oxley Act, to the Fund, the Manager and certain affiliates of the Manager. The Audit Committee also reviews reports concerning the valuation of certain investments.

The members of the Regulatory & Oversight Committee are Matthew P. Fink (Chairman), David K. Downes, Phillip A. Griffiths, Joel W. Motley, Mary Ann Tynan and Joseph M. Wikler. The Regulatory & Oversight Committee evaluates and reports to the Board on the Fund's contractual arrangements, including the Investment Advisory and Distribution Agreements, Transfer Agency and Shareholder Service Agreements and custodian agreements as well as the policies and procedures adopted by the Fund to comply with the Investment Company Act and other applicable law. The Regulatory & Oversight Committee also reviews reports from the Manager's Risk Management Department and Chief Compliance Officer among other duties as set forth in the Regulatory & Oversight Committee's Charter. These reports, and others concerning investment, operational and other risks to the Funds are shared with, and discussed by, the full Board.

The members of the Governance Committee are Joel W. Motley (Chairman), Matthew P. Fink, Mary F. Miller, Mary Ann Tynan and Peter I. Wold. The Governance Committee reviews the Fund's governance guidelines, the adequacy of the Fund's Codes of Ethics, and develops qualification criteria for Board members consistent with the Fund's governance guidelines, provides the Board with recommendations for voting portfolio securities held by the Fund, monitors the Fund's proxy voting, and coordinates with organizations representing the independent directors of mutual funds among other duties set forth in the Governance Committee's Charter.

The Governance Committee's functions also include the nomination of Trustees/Directors, including Independent Trustees/Directors, for election to the Board. The full Board elects new Trustees/Directors except for those instances when a shareholder vote is required.

The Governance Committee will consider nominees recommended by Independent Trustees/Directors or recommended by any other Board members including Board members affiliated with the Fund's Manager. The Governance Committee may consider the advice and recommendation of the Manager and its affiliates in selecting nominees, but need not do so. Upon Board approval, the Governance Committee may retain an executive search firm to assist in screening potential candidates and may also use the services of legal, financial, or other external counsel that it deems necessary or desirable in the screening process. To date, the Governance Committee has been able to identify from its own resources an ample number of qualified candidates. However, under the current policy of the Board, if the Board determines that a vacancy exists or is likely to exist, the Governance Committee will include candidates recommended by the Fund's shareholders in its consideration of nominees.

Shareholders wishing to submit a nominee for election to the Board may do so by mailing their submission to the offices of OppenheimerFunds, Inc., Two World Financial Center, 225 Liberty Street, 11th Floor, New York, New York 10281-1008, to the attention of the Board of Trustees/Directors of the applicable Fund, c/o the Secretary of the Fund. Submissions should, at a minimum, be accompanied by the following: (1) the name, address, and business, educational, and/or other pertinent background of the person being recommended; (2) a statement concerning whether the person is an "interested person" as defined in the Investment Company Act; (3) any other information that the Fund would be required to include in a proxy statement concerning the person if he or she was nominated; and (4) 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. Shareholders should note that a person who owns securities issued by Massachusetts Mutual Life Insurance Company (the parent company of the Manager) would be deemed an "interested person" under the Investment Company Act. 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."

The Governance Committee has not established specific qualifications that it believes must be met by a nominee. In evaluating nominees, the Governance 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; and whether the individual would be deemed an "audit committee financial expert" within the meaning of applicable SEC rules. The Governance Committee also considers whether the individual's background, skills, and experience will complement, and add to the diversity of, the background, skills, and experience of other Trustees/Directors, and will contribute to the Board's deliberations. There is no difference in the manner in which the Governance Committee evaluates a nominee based on whether the nominee is recommended by a shareholder. Candidates are expected to provide a mix of attributes, experience, perspective and skills necessary to effectively advance the interests of shareholders.

Below is a brief discussion of the specific experience, qualifications, attributes or skills of each Board member that led the Board to conclude that he or she should serve as a Trustee/Director of the Fund.

Each independent trustee/director has served on the Board for the number of years listed below, during the course of which he or she has become familiar with the Fund's (and other Oppenheimer funds') financial, accounting, regulatory and investment matters and has contributed to the Board's deliberations. Each Trustee's/Director's outside professional experience is outlined in the table of Biographical Information, below.

Shareholder and Trustee Liability. The Fund's Declaration of Trust contains an express disclaimer of shareholder and Trustee liability for the Fund's obligations. It also provides for indemnification and reimbursement of expenses out of the Fund's property for any shareholder held personally liable for its obligations. The Declaration of Trust also states that, upon request, the Fund shall assume the defense of any claim made against a shareholder for any act or obligation of the Fund and shall satisfy any judgment on that claim. The Fund's contractual arrangements state that any person doing business with the Fund (and each shareholder of the Fund) agrees under its Declaration of Trust to look solely to the assets of the Fund for satisfaction of any claim or demand that may arise out of any dealings with the Fund. Additionally, the Trustees shall have no personal liability to any such person, to the extent permitted by law. Although Massachusetts law permits a shareholder of a business trust (such as the Fund) to be held personally liable as a "partner" under certain circumstances, the risk that a Fund shareholder will incur financial loss from being held liable as a "partner" of the Fund is limited to the relatively remote circumstances in which the Fund would be unable to meet its obligations.

In addition, none of the Independent Trustees (nor any of their immediate family members) owns securities of either the Manager or the Distributor or of any entity directly or indirectly controlling, controlled by or under common control with the Manager or the Distributor.

Retirement Plan for Trustees. The New York Board Funds adopted a retirement plan that provided for payments to retired Independent Trustees of up to 80% of the average compensation paid during a Trustee's five years of service in which the highest compensation was received. A Trustee needed to serve as director or trustee for any of the New York Board Funds for at least seven years to be eligible for retirement plan benefits and to serve for at least 15 years to be eligible for the maximum benefit. The Board discontinued the retirement plan with respect to new accruals as of December 31, 2006 (the "Freeze Date"). Each Trustee that continued to serve on the Board of any of the New York Board Funds after the Freeze Date (each such Trustee a "Continuing Board Member") was able to elect to have his accrued benefit as of that date (i.e., an amount equivalent to the actuarial present value of his benefit under the retirement plan as of the Freeze Date) (i) paid at once or over time, (ii) rolled into the Compensation Deferral Plan described below, or (iii) in the case of Continuing Board Members having at least seven years of service as of the Freeze Date paid in the form of an annual benefit or joint and survivor annual benefit. The Board determined to freeze the retirement plan after considering a recent trend among corporate boards of directors to forego retirement plan payments in favor of current compensation.

Compensation Deferral Plan. The Board of Trustees has adopted a Compensation Deferral Plan for Independent Trustees that enables them to elect to defer receipt of all or a portion of the annual fees they are entitled to receive from certain Funds. Under the plan, the compensation deferred by a Trustee is periodically adjusted as though an equivalent amount had been invested in shares of one or more Oppenheimer funds selected by the Trustee. The amount paid to the Trustee under the plan will be determined based on the amount of compensation deferred and the performance of the selected funds.

Deferral of the Trustees' fees under the plan will not materially affect a Fund's assets, liabilities or net income per share. The plan will not obligate a fund to retain the services of any Trustee or to pay any particular level of compensation to any Trustee. Pursuant to an Order issued by the SEC, a fund may invest in the funds selected by the Trustee under the plan without shareholder approval for the limited purpose of determining the value of the Trustee's deferred compensation account.

Major Shareholders. As of July 2, 2010 the only persons or entities who owned of record, or who were known by the Fund to own beneficially, 5% or more of any class of the Fund's outstanding shares were:

The Manager

The Manager is wholly-owned by Oppenheimer Acquisition Corp., a holding company primarily owned by Massachusetts Mutual Life Insurance Company, a global, diversified insurance and financial services company.

Code of Ethics. The Fund, the Manager and the Distributor have a Code of Ethics. It is designed to detect and prevent improper personal trading by portfolio managers and certain other employees ("covered persons") that could compete with or take advantage of the Fund's portfolio transactions. Covered persons include persons with knowledge of the investments and investment intentions of the Fund and/or other funds advised by the Manager. The Code of Ethics does permit personnel subject to the Code to invest in securities, including securities that may be purchased or held by the Fund, subject to a number of restrictions and controls. Compliance with the Code of Ethics is carefully monitored and enforced by the Manager.

The Code of Ethics is an exhibit to the Fund's registration statement filed with the SEC. It can be viewed as part of the Fund's registration statement on the SEC's EDGAR database at the SEC's website at www.sec.gov and can be reviewed and copied at the SEC's Public Reference Room in Washington, D.C.

Portfolio Proxy Voting. The Fund has adopted Portfolio Proxy Voting Policies and Procedures, which include Proxy Voting Guidelines, under which the Fund votes proxies relating to securities held by the Fund ("portfolio proxies"). OppenheimerFunds, Inc. generally undertakes to vote portfolio proxies with a view to enhancing the value of the company's stock held by the Funds. The Fund has retained an independent, third party proxy voting agent to vote portfolio proxies in accordance with the Fund's Proxy Voting Guidelines and to maintain records of such portfolio proxy voting. The Portfolio Proxy Voting Policies and Procedures include provisions to address conflicts of interest that may arise between the Fund and the Manager or the Manager's affiliates or business relationships. Such a conflict of interest may arise, for example, where the Manager or an affiliate of the Manager manages or administers the assets of a pension plan or other investment account of the portfolio company soliciting the proxy or seeks to serve in that capacity. The Manager and its affiliates generally seek to avoid such material conflicts of interest by maintaining separate investment decision making processes to prevent the sharing of business objectives with respect to proposed or actual actions regarding portfolio proxy voting decisions. Additionally, the Manager employs the following procedures, as long as OFI determines that the course of action is consistent with the best interests of the Fund and its shareholders: (1) if the proposal that gives rise to the conflict is specifically addressed in the Proxy Voting Guidelines, the Manager will vote the portfolio proxy in accordance with the Proxy Voting Guidelines, provided that they do not provide discretion to the Manager on how to vote on the matter; (2) if such proposal is not specifically addressed in the Proxy Voting Guidelines or the Proxy Voting Guidelines provide discretion to the Manager on how to vote, the Manager will vote in accordance with the third-party proxy voting agent's general recommended guidelines on the proposal provided that the Manager has reasonably determined that there is no conflict of interest on the part of the proxy voting agent; and (3) if neither of the previous two procedures provides an appropriate voting recommendation, the Manager may retain an independent fiduciary to advise the Manager on how to vote the proposal or may abstain from voting. The Proxy Voting Guidelines' provisions with respect to certain routine and non-routine proxy proposals are summarized below:

• The Fund evaluates director nominees on a case-by-case basis, examining the following factors, among others: composition of the board and key board committees, experience and qualifications, attendance at board meetings, corporate governance provisions and takeover activity, long-term company performance and the nominee's investment in the company.

• The Fund generally supports proposals requiring the position of chairman to be filled by an independent director unless there are compelling reasons to recommend against the proposal such as a counterbalancing governance structure.

• The Fund generally supports proposals asking that a majority of directors be independent. The Fund generally supports proposals asking that a board audit, compensation, and/or nominating committee be composed exclusively of independent directors.

• The Fund generally supports shareholder proposals to reduce a super-majority vote requirement, and opposes management proposals to add a super-majority vote requirement.

• The Fund generally supports proposals to allow shareholders the ability to call special meetings.

• The Fund generally supports proposals to allow or make easier shareholder action by written consent.

• The Fund generally votes against proposals to create a new class of stock with superior voting rights.

• The Fund generally votes against proposals to classify a board.

• The Fund generally supports proposals to eliminate cumulative voting.

• The Fund generally opposes re-pricing of stock options without shareholder approval.

• The Fund generally supports proposals to require majority voting for the election of directors.

• The Fund generally supports proposals seeking additional disclosure of executive and director pay information.

• The Fund generally supports proposals seeking disclosure regarding the company's, board's or committee's use of compensation consultants.

• The Fund generally supports "pay-for-performance" proposals that align a significant portion of total compensation of senior executives to company performance.

• The Fund generally supports having shareholder votes on poison pills.

• The Fund generally supports proposals calling for companies to adopt a policy of not providing tax gross-up payments.

• In the case of social, political and environmental responsibility issues, the Fund will generally abstain where there could be a detrimental impact on share value or where the perceived value if the proposal was adopted is unclear or unsubstantiated. The Fund generally supports proposals that would clearly have a discernible positive impact on short- or long-term share value, or that would have a presently indiscernible impact on short- or long-term share value but promotes general long-term interests of the company and its shareholders.

The Fund is required to file Form N-PX, with its complete proxy voting record for the 12 months ended June 30th, no later than August 31st of each year. The Fund's Form N-PX filing is available (i) without charge, upon request, by calling the Fund toll-free at 1.800.525.7048 and (ii) on the SEC's website at www.sec.gov.

The Investment Advisory Agreement. The Manager provides investment advisory and management services to the Fund under an investment advisory agreement between the Manager and the Fund. The Manager selects securities for the Fund's portfolio and handles its day-to-day business. The portfolio managers of the Fund are employed by the Manager and are principally responsible for the day-to-day management of the Fund's portfolio. Other members of the Manager's Equity Portfolio Department provide the portfolio managers with counsel and support in managing the Fund's portfolio.

The agreement requires the Manager, at its expense, to provide the Fund with adequate office space, facilities and equipment. It also requires the Manager to provide and supervise the activities of all administrative and clerical personnel required to provide effective administration for the Fund. Those responsibilities include the compilation and maintenance of records with respect to its operations, the preparation and filing of specified reports, and composition of proxy materials and registration statements for continuous public sale of shares of the Fund.

The Fund pays expenses not expressly assumed by the Manager under the investment advisory agreement. The investment advisory agreement lists examples of expenses paid by the Fund. The major categories relate to interest, taxes, brokerage commissions, fees to certain Directors/Trustees, legal and audit expenses, custodian and transfer agent expenses, share issuance costs, certain printing and registration costs and non-recurring expenses, including litigation costs. The management fees paid by the Fund to the Manager are calculated at the rates described in the Prospectus, which are applied to the assets of the Fund as a whole. The fees are allocated to each class of shares based upon the relative proportion of the Fund's net assets represented by that class. The management fees paid by the Fund to the Manager during its last three fiscal years were:

The investment advisory agreement states that in the absence of willful misfeasance, bad faith, gross negligence in the performance of its duties or reckless disregard of its obligations and duties under the investment advisory agreement, the Manager is not liable for any loss the Fund sustains in connection with matters to which the agreement relates.

The agreement permits the Manager to act as an investment adviser for any other person, firm or corporation and to use the name "Oppenheimer" in connection with other investment companies for which it may act as investment adviser or general distributor. If the Manager shall no longer act as investment adviser to the Fund, the Manager may withdraw the right of the Fund to use the name "Oppenheimer" as part of its name.

Pending Litigation. Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds ("Defendant Funds") advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund's investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys' fees and litigation expenses. 

In 2009, what are claimed to be derivative lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys' fees and litigation expenses.

The Distributor and another subsidiary of the Manager have been named as defendants in a putative class action filed in federal court in 2010. The plaintiff, a participant in the State of Texas' college savings plan, asserts claims on behalf of all persons who invested in qualified 529 plans managed by these subsidiaries of the Manager and which held investments in a certain mutual fund managed by the Manager and distributed by the Distributor. Plaintiff alleges causes of action for "improper investments," breach of fiduciary duty," and "punitive damages" arising from that fund's investments in 2008 and 2009. The Manager and these subsidiaries believe that the complaint is legally deficient and intend to defend the case vigorously.

Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm ("Madoff"). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys' fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds' Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

Portfolio Managers. The Fund's portfolio is managed by a team of investment professionals, including, Daniel G. Loughran, Scott S. Cottier, Troy E. Willis, Mark R. DeMitry, Michael L. Camarella and Marcus V. Franz (each is referred to as a "Portfolio Manager" and collectively they are referred to as the "Portfolio Managers") who are responsible for the day-to-day management of the Fund's investments.

• Other Accounts Managed. In addition to managing the Fund's investment portfolio, the members of the portfolio management team also manage other investment portfolios and other accounts on behalf of the Manager or its affiliates. The following table provides information regarding those portfolios and accounts as of March 31, 2010:

Portfolio Manager	Registered Investment Companies Managed1	Total Assets in Registered Investment Companies Managed2	Other Pooled Investment Vehicles Managed	Total Assets in Other Pooled Investment Vehicles Managed	Other Accounts Managed	Total Assets in Other Accounts Managed3
Daniel G. Loughran	10	$26,513	None	$0	None	$0

1. The Portfolio Managers manage 18 registered investment companies, including the 8 funds covered in this SAI. As of 3/31/10, those funds had the following total assets (in millions, approximate): AZ ($47.1), MD ($87.6), MA ($74.2), MI ($46.8), MN ($46), NC ($96), OH ($81.2), and VA ($107.7).
2. In millions.
3. Does not include personal accounts of portfolio managers and their families, which are subject to the Code of Ethics.

As indicated above, the Portfolio Managers may also manage other funds and accounts. At different times, the Fund's Portfolio Managers may manage other funds or accounts with investment objectives and strategies similar to those of the Fund, or they may manage funds or accounts with different investment objectives and strategies. At times, those responsibilities could potentially conflict with the interests of the Fund. That may occur whether the investment objectives and strategies of the other funds and accounts are the same as, or different from, the Fund's investment objectives and strategies. For example, the Portfolio Managers may need to allocate investment opportunities between the Fund and another fund or account having similar objectives or strategies, or they may need to execute transactions for another fund or account that could have a negative impact on the value of securities held by the Fund. Not all funds and accounts advised by the Manager have the same management fee. If the management fee structure of another fund or account is more advantageous to the Manager than the fee structure of the Fund, the Manager could have an incentive to favor the other fund or account. However, the Manager's compliance procedures and Code of Ethics recognize the Manager's obligation to treat all of its clients, including the Fund, fairly and equitably, and are designed to preclude the Portfolio Managers from favoring one client over another. It is possible, of course, that those compliance procedures and the Code of Ethics may not always be adequate to do so.

Compensation of the Portfolio Managers. The Fund's Portfolio Managers are employed and compensated by the Manager, not the Fund. Under the Manager's compensation program for its portfolio managers and portfolio analysts, Fund performance is the most important element of compensation with a portion of annual cash compensation based on relative investment performance results of the funds or accounts they manage, rather than on the financial success of the Manager. This is intended to align the portfolio managers and analysts' interests with the success of the funds and accounts and their shareholders. The Manager's compensation structure is designed to attract and retain highly qualified investment management professionals and to reward individual and team contributions toward creating shareholder value. As of the Fund's most recently completed year-end, the Portfolio Managers' compensation consisted of three elements: a base salary, an annual discretionary bonus and eligibility to participate in long-term awards of options and stock appreciation rights in regard to the common stock of the Manager's holding company parent, as well as restricted shares of such common stock. Senior portfolio managers may be eligible to participate in the Manager's deferred compensation plan.

The base pay component of each portfolio manager is reviewed regularly to ensure that it reflects the performance of the individual, is commensurate with the requirements of the particular portfolio, reflects any specific competence or specialty of the individual manager, and is competitive with other comparable positions. The annual discretionary bonus is determined by senior management of the Manager and is based on a number of factors, including a fund's pre-tax performance for periods of up to five years, measured against an appropriate Lipper benchmark selected by management. The majority (80%) is based on three and five year data, with longer periods weighted more heavily. Below median performance in all three periods' results in an extremely low, and in some cases no, performance based bonus. Other factors considered include management quality (such as style consistency, risk management, sector coverage, team leadership and coaching) and organizational development. The Portfolio Managers' compensation is not based on the total value of the Fund's portfolio assets, although the Fund's investment performance may increase those assets. The compensation structure is also intended to be internally equitable and serve to reduce potential conflicts of interest between the Fund and other funds and accounts managed by the Portfolio Managers.

The Lipper benchmark for the Portfolio Managers with respect to the Fund is its state's Lipper - Municipal Debt Funds category. The compensation structure of the other funds and accounts managed by the Portfolio Managers are generally the same as the compensation structure of the Fund, described above.

•  Ownership of Fund Shares. As of March 31, 2010, the Portfolio Manager(s) beneficially owned shares of the Fund as follows:

Portfolio Manager	Range of Shares Beneficially Owned in the Fund
Daniel G. Loughran	None
Scott S. Cottier	None
Troy E. Willis	None
Mark R. DeMitry	None
Michael L. Camarella	None
Marcus V. Franz	None

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement. One of the duties of the Manager under the investment advisory agreement is to arrange the portfolio transactions for the Fund. The advisory agreement contains provisions relating to the employment of broker-dealers for that purpose. The advisory agreement authorizes the Manager to employ broker-dealers, including "affiliated brokers," as that term is defined in the Investment Company Act, that the Manager thinks, in its best judgment based on all relevant factors, will implement the policy of the Fund to obtain the "best execution" of the Fund's portfolio transactions. "Best execution" means executing trades in a manner that the total cost or proceeds is the most favorable under the circumstances. Some of the circumstances that may influence this decision are: cost (brokerage commission or dealer spread), size of order, difficulty of order, and the firm's ability to provide prompt and reliable execution.

The Manager need not seek competitive commission bidding. However, the Manager is expected to be aware of the current rates of eligible brokers and to minimize the commissions paid to the extent consistent with the interests and policies of the Fund as established by its Board. The Fund is not required to pay the lowest available commission. Under the investment advisory agreement, in choosing brokers to execute portfolio transactions for the Fund, the Manager may select brokers (other than affiliates) that provide both brokerage and research services to the Fund. The commissions paid to those brokers may be higher than another qualified broker would charge, if the Manager makes a good faith determination that the commission is fair and reasonable in relation to the services provided.

Brokerage Practices Followed by the Manager. The Manager allocates brokerage for the Fund subject to the provisions of the investment advisory agreement and other applicable rules and procedures described below.

The Manager's portfolio managers directly place trades and allocate brokerage based upon their judgment as to the execution capability of the broker or dealer. The Manager's executive officers supervise the allocation of brokerage. 

Most securities purchases made by the Fund are in principal transactions at net prices. (i.e., without commissions). The Fund usually deals directly with the selling or purchasing principal or market maker without incurring charges for the services of a broker on its behalf.  Portfolio securities purchased from underwriters include a commission or concession paid by the issuer to the underwriter in the price of the security.  Portfolio securities purchased from dealers include a spread between the bid and asked price.  Therefore, the Fund generally does not incur substantial brokerage costs. On occasion, however, the Manager may determine that a better price or execution may be obtained by using the services of a broker on an agency basis. In that situation, the Fund would incur a brokerage commission.

Other funds advised by the Manager have investment policies similar to those of the Fund.  Those other funds may purchase or sell the same securities as the Fund at the same time as the Fund, which could affect the supply and price of the securities.  When possible, the Manager tries to combine concurrent orders to purchase or sell the same security by more than one of the funds managed by the Manager or its affiliates. The transactions under those combined orders are generally allocated on a pro rata basis based on the fund's respective net asset sizes and other factors, including the fund's cash flow requirements, investment policies and guidelines and capacity.

Rule 12b-1 under the Investment Company Act prohibits any fund from compensating a broker or dealer for promoting or selling the fund's shares by (1) directing to that broker or dealer any of the fund's portfolio transactions, or (2) directing any other remuneration to that broker or dealer, such as commissions, mark-ups, mark downs or other fees from the fund's portfolio transactions, that were effected by another broker or dealer (these latter arrangements are considered to be a type of "step-out" transaction). In other words, a fund and its investment adviser cannot use the fund's brokerage for the purpose of rewarding broker-dealers for selling a fund's shares.

However, the Rule permits funds to effect brokerage transactions through firms that also sell fund shares, provided that certain procedures are adopted to prevent a quid pro quo with respect to portfolio brokerage allocations. As permitted by the Rule, the Manager has adopted procedures (and the Fund's Board of Trustees has approved those procedures) that permit the Fund to execute portfolio securities transactions through brokers or dealers that also promote or sell shares of the Fund, subject to the "best execution" considerations discussed above. Those procedures are designed to prevent: (1) the Manager's personnel who effect the Fund's portfolio transactions from taking into account a broker's or dealer's promotion or sales of the Fund shares when allocating the Fund's portfolio transactions, and (2) the Fund, the Manager and the Distributor from entering into agreements or understandings under which the Manager directs or is expected to direct the Fund's brokerage directly, or through a "step-out" arrangement, to any broker or dealer in consideration of that broker's or dealer's promotion or sale of the Fund's shares or the shares of any of the other Oppenheimer funds.

The investment advisory agreement permits the Manager to allocate brokerage for research services. The research services provided by a particular broker may be useful both to the Fund and to one or more of the other accounts advised by the Manager or its affiliates. Investment research may be supplied to the Manager by a broker through which trades are placed or by a third party at the instance of the broker.

Investment research services include information and analysis on particular companies and industries as well as market or economic trends and portfolio strategy, market quotations for portfolio evaluations, analytical software and similar products and services. If a research service also assists the Manager in a non-research capacity (such as bookkeeping or other administrative functions), then only the percentage or component that provides assistance to the Manager in the investment decision making process may be paid in commission dollars.

Although the Manager currently does not do so, the Board of Trustees may permit the Manager to use stated commissions on secondary fixed-income agency trades to obtain research if the broker represents to the Manager that: (i) the trade is not from or for the broker's own inventory, (ii) the trade was executed by the broker on an agency basis at the stated commission, and (iii) the trade is not a riskless principal transaction. The Board may also permit the Manager to use commissions on fixed-price offerings to obtain research in the same manner as is permitted for agency transactions.

The research services provided by brokers broaden the scope and supplement the research activities of the Manager. That research provides additional views and comparisons for consideration, and helps the Manager to obtain market information for the valuation of securities that are either held in the Fund's portfolio or are being considered for purchase. The Manager provides information to the Board about the commissions paid to brokers furnishing such services, together with the Manager's representation that the amount of such commissions was reasonably related to the value or benefit of such services.

During the fiscal years ended March 31, 2008, 2009 and 2010, none of the Funds covered in this SAI executed transactions or paid commissions to firms that provide research services.

Distribution and Service Arrangements

The Distributor. Under its General Distributor's Agreement with the Fund, the Distributor acts as the Fund's principal underwriter in the continuous public offering of the Fund's shares. The Distributor bears the expenses normally attributable to sales, including advertising and the cost of printing and mailing prospectuses, other than those furnished to existing shareholders. The Distributor is not obligated to sell a specific number of shares.

The sales charges and concessions paid to, or retained by, the Distributor from the sale of shares and the contingent deferred sales charges ("CDSCs") retained by the Distributor on the redemption of shares during the Fund's three most recent fiscal years are shown in the tables below.

1. Includes amounts retained by a broker-dealer that is an affiliate or a parent of the Distributor.
2.  The Distributor advances concession payments to financial intermediaries for certain sales of Class A shares and for sales of Class B and Class C shares from its own resources at the time of sale.

Distribution and Service (12b-1) Plans. The Fund has adopted a Service Plan for Class A shares and Distribution and Service Plans for Class B and Class C shares under Rule 12b-1 of the Investment Company Act. Under those plans the Fund pays the Distributor for all or a portion of its costs incurred in connection with the distribution and/or servicing of the shares of the particular class. Each plan has been approved by a vote of the Board, including a majority of the Independent Trustees, cast in person at a meeting called for the purpose of voting on that plan. The Independent Trustees are not "interested persons" of the Fund and do not have any direct or indirect financial interest in the operation of the distribution plan or any agreement under the plan, in accordance with Rule 12b-1 of the Investment Company Act.

Under the plans, the Manager and the Distributor may make payments to affiliates. In their sole discretion, they may also from time to time make substantial payments from their own resources, which include the profits the Manager derives from the advisory fees it receives from the Fund, to compensate brokers, dealers, financial institutions and other intermediaries for providing distribution assistance and/or administrative services or that otherwise promote sales of the Fund's shares. These payments, some of which may be referred to as "revenue sharing," may relate to the Fund's inclusion on a financial intermediary's preferred list of funds offered to its clients.

A plan continues in effect from year to year only if the Fund's Board and its Independent Trustees/Directors vote annually to approve its continuance at an in person meeting called for that purpose. A plan may be terminated at any time by the vote of a majority of the Independent Trustees/Directors or by the vote of the holders of a "majority" (as defined in the Investment Company Act) of the outstanding shares of the Class of shares to which it applies.

The Board and the Independent Trustees/Directors must approve all material amendments to a plan. An amendment to materially increase the amount of payments to be made under a plan must also be approved by shareholders of any affected class. Because Class B shares of the Fund automatically convert into Class A shares 72 months after purchase, the shareholders of both Class A and Class B, voting separately by class, must approve a proposed amendment to the Class A plan that would materially increase payments under that plan.

At least quarterly while the plans are in effect, the Treasurer of the Fund will provide the Board with separate written reports on the plans for its review. The reports will detail the amount of all payments made under a plan and the purpose for which the payments were made. Those reports are subject to the review and approval of the Independent Trustees/Directors.

While each plan is in effect, the Independent Trustees/Directors of the Fund will select and nominate any other Independent Trustees/Directors. This does not prevent the involvement of others in the selection and nomination process as long as the final decision is made by a majority of the Independent Trustees/Directors.

No payment will be made to any recipient for any share class unless, during the applicable period, the aggregate net asset value of Fund shares of the class held by the recipient (for itself and its customers) exceeds a minimum amount that may be set by a majority of the Independent Trustees/Directors from time to time.

Class A Service Plan. Under the Class A service plan, the Distributor currently uses the fees it receives from the Fund to pay brokers, dealers and other financial institutions (referred to as "recipients") for personal and account maintenance services they provide for their customers who hold Class A shares. Those services may include answering customer inquiries about the Fund, assisting in establishing and maintaining Fund accounts, making the Fund's investment plans available and providing other services at the request of the Fund or the Distributor. The Class A service plan permits the Fund to reimburse the Distributor at an annual rate of up to 0.25% of the Class A average net assets. The Distributor makes payments to recipients periodically at an annual rate of not more than 0.25% of the Class A average net assets held in the accounts of the recipient or it customers.

The Distributor does not receive or retain the service fee for Class A share accounts for which the Distributor is listed as the broker-dealer of record. While the plan permits the Board to authorize payments to the Distributor to reimburse itself for those services, the Board has not yet done so, except with respect to shares purchased prior to March 1, 2007 by certain group retirement plans that were established prior to March 1, 2001 ("grandfathered retirement plans").

Prior to March 1, 2007, the Distributor paid the 0.25% first year service fee for grandfathered retirement plans in advance and retained the service fee paid by the Fund with respect to those shares for the first year. After those shares are held for a year, the Distributor pays the ongoing service fees to recipients on a periodic basis. If those shares were redeemed within the first year after their purchase, the recipient of the service fees on those shares was obligated to repay the Distributor a pro rata portion of the advance payment of the fees. If those shares were redeemed within 18 months, they were subject to a CDSC. For Class A shares purchased in grandfathered retirement plans on or after March 1, 2007, the Distributor does not make any payment in advance and does not retain the service fee for the first year and the shares are not subject to a CDSC.

The table below shows the dollar amount which was retained by the Distributor under the arrangement described above, regarding grandfathered retirement accounts, including money paid to an affiliate of the Distributor's parent company. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent years. The Distributor may not use payments received under the Class A plan to pay any of its interest expenses, carrying charges, or other financial costs, or allocation of overhead.  For the fiscal year ended March 31, 2010 payments under the Class A service plan were as follows:

Class B and Class C Distribution and Service Plans. Under the Class B and Class C Distribution and Service Plans (each a "Plan" and together the "Plans"), the Fund pays the asset-based sales charge (the "distribution fee") to the Distributor for its services in distributing Class B and Class C shares. The distribution fee allows investors to buy Class B and Class C shares without a front-end sales charge, while allowing the Distributor to compensate dealers that sell those shares. The Distributor may use the service fees it receives under the Plans to pay recipients for providing services similar to the services provided under the Class A service plan, described above.

Payments under the Plans are made in recognition that the Distributor:

• pays sales concessions to authorized brokers and dealers at the time of sale or as an ongoing concession,

• pays the service fees in advance or periodically, as described below,

• may finance payment of sales concessions or the advance of the service fee payments to recipients under the Plans, or may provide such financing from its own resources or from the resources of an affiliate,

• employs personnel to support distribution of Class B and Class C shares,

• bears the costs of sales literature, advertising and prospectuses (other than those furnished to current shareholders) and certain other distribution expenses,

• may not be able to adequately compensate dealers that sell Class B and Class C shares without receiving payment under the Plans and therefore may not be able to offer such Classes for sale absent the Plans,

• receives payments under the Plans consistent with the service and distribution fees paid by other non-proprietary funds that charge 12b-1 fees,

• may use the payments under the Plan to include the Fund in various third-party distribution programs that might increase sales of Fund shares,

• may experience increased difficulty selling the Fund's shares if Plan payments were discontinued, because most competitor funds have plans that pay dealers as much or more for distribution services than the amounts currently being paid by the Fund, and

• may not be able to continue providing the same quality of distribution efforts and services, or to obtain such services from brokers and dealers, if Plan payments were discontinued.

Distribution fees on Class B shares are generally retained by the Distributor. If a dealer has a special agreement with the Distributor, the Distributor may pay the Class B distribution fees to recipients periodically in lieu of paying the sales concession in advance at the time of purchase. The Distributor retains the distribution fee on Class C shares during the first year and then pays it as an ongoing concession to recipients.

Service fees for the first year after Class B and Class C shares are purchased, are generally paid to recipients in advance. After the first year, the Distributor pays the service fees to recipients periodically. Under the Plans, the Distributor is permitted to retain the service fees or to pay recipients the service fee on a periodic basis, without payment in advance. If a recipient has a special agreement with the Distributor, the Distributor may pay the Class B service fees to recipients periodically in lieu of paying the first year fee in advance. If Class B and Class C shares are redeemed during the first year after their purchase, a recipient of service fees on those shares will be obligated to repay a pro rata portion of the advance payment to the Distributor. Shares purchased by exchange do not qualify for the advance service fee payment.

Class B and Class C shares may not be purchased by a new investor directly from the Distributor without the investor designating another registered broker-dealer. If a current investor no longer has another broker-dealer of record for an existing account, the Distributor is automatically designated as the broker-dealer of record, but solely for the purpose of acting as the investor's agent to purchase the shares. In those cases, the Distributor retains the distribution fees paid on Class B and Class C shares, but does not retain any service fees as to the assets represented by that account.

Each Plan provides for the Distributor to be compensated at a flat rate, whether the Distributor's distribution expenses for a period are more or less than the amounts paid by the Fund under the relevant Plan. During a calendar year, the Distributor's actual expenses in selling Class B and Class C shares may be more than the distribution fees paid to the Distributor under the Plans and the CDSC's collected on redeemed shares. Those excess expenses are carried over on the Distributor's books and may be recouped from distribution fees paid by the Fund in future years. However, the Distributor has voluntarily agreed to cap the amount that may be carried over from year to year and recouped for certain categories of expenses at 0.70% of annual gross sales of shares of the Fund. The capped expenses under the Plans are (i) expenses the Distributor has incurred that represent compensation and expenses of its sales personnel and (ii) other direct distribution costs it has incurred, such as sales literature, state registration fees, advertising and prospectuses used to offer Fund shares. If those categories of expenses exceed the capped amount, the Distributor would bear the excess costs. If a Plan were to be terminated by the Fund, the Fund's Board may allow the Fund to continue payments of the distribution fees to the Distributor for its services in distributing shares before the Plan was terminated.

The distribution and service fees under each Plan are computed on the average of the net asset value of shares in the respective class, determined as of the close of each regular business day. The distribution and service fees increase the annual Class B and Class C expenses by 1.00% of net assets.

Payments to Fund Intermediaries

Financial intermediaries may receive various forms of compensation or reimbursement from the Fund in the form of distribution and service (12b-1) plan payments as described above. They may also receive payments or concessions from the Distributor, derived from sales charges paid by the financial intermediary's clients, also as described in this SAI. In addition, the Manager and the Distributor (including their affiliates) may make payments to financial intermediaries in connection with the intermediaries' offering and sales of Fund shares and shares of other Oppenheimer funds, or their provision of marketing or promotional support, transaction processing or administrative services. Among the financial intermediaries that may receive these payments are brokers or dealers who sell or hold shares of the Fund, banks (including bank trust departments), registered investment advisers, insurance companies, retirement plan or qualified tuition program administrators, third party administrators, recordkeepers or other institutions that have selling, servicing or similar arrangements with the Manager or the Distributor. The payments to financial intermediaries vary by the types of product sold, the features of the Fund share class and the role played by the intermediary.

Types of payments to financial intermediaries may include, without limitation, all or portions of the following, and/or the Fund, or an investor buying or selling Fund shares may pay:

• an initial front-end sales charge, all or a portion of which is payable by the Distributor to financial intermediaries (see the "About Your Account" section in the Prospectus);

• ongoing asset-based distribution and/or service fees (described in the section "About the Fund - Distribution and Service (12b-1) Plans" above);

• shareholder servicing expenses that are paid from Fund assets to reimburse the Manager or the Distributor for Fund expenses they incur for providing omnibus accounting, recordkeeping, networking, sub-transfer agency or other administrative or shareholder services (including retirement plan and 529 plan administrative services fees).

In addition, the Manager or Distributor may, at their discretion, make the following types of payments from their own respective resources, which may include profits the Manager derives from investment advisory fees paid by the Fund. Payments are made based on the guidelines established by the Manager and Distributor, subject to applicable law. These payments are often referred to as "revenue sharing" payments, and may include:

• compensation for marketing support, support provided in offering shares in the Fund or other Oppenheimer funds through certain trading platforms and programs, and transaction processing or other services;

• other compensation to the extent the payment is not prohibited by law or by any self-regulatory agency, such as FINRA.

Although brokers or dealers that sell Fund shares may also act as a broker or dealer in connection with the purchase or sale of portfolio securities by the Fund or other Oppenheimer funds, the Manager does not consider a financial intermediary's sales of shares of the Fund or other Oppenheimer funds when choosing brokers or dealers to effect portfolio transactions for the Fund or other Oppenheimer funds.

Revenue sharing payments can pay for distribution-related or asset retention items including, without limitation:

• transactional support, one-time charges for setting up access for the Fund or other Oppenheimer funds on particular trading systems, and paying the intermediary's networking fees;

• program support, such as expenses related to including the Oppenheimer funds in retirement plans, college savings plans, fee-based advisory or wrap fee programs, fund "supermarkets", bank or trust company products or insurance companies' variable annuity or variable life insurance products;

• placement on the dealer's list of offered funds and providing representatives of the Distributor with access to a financial intermediary's sales meetings, sales representatives and management representatives; or

• firm support, such as business planning assistance, advertising, or educating a financial intermediary's sales personnel about the Oppenheimer funds and shareholder financial planning needs.

These payments may provide an incentive to financial intermediaries to actively market or promote the sale of shares of the Fund or other Oppenheimer funds, or to support the marketing or promotional efforts of the Distributor in offering shares of the Fund or other Oppenheimer funds. In addition, some types of payments may provide a financial intermediary with an incentive to recommend the Fund or a particular share class. Financial intermediaries may earn profits on these payments, since the amount of the payments may exceed the cost of providing the services. Certain of these payments are subject to limitations under applicable law. Financial intermediaries may categorize and disclose these arrangements to their clients and to members of the public in a manner different from the disclosures in the Fund's Prospectus and this SAI. You should ask your financial intermediary for information about any payments it receives from the Fund, the Manager or the Distributor and any services it provides, as well as the fees and commissions it charges.

For the year ended December 31, 2009, the following financial intermediaries and/or their affiliates (which in some cases are broker-dealers) offered shares of the Oppenheimer funds and received revenue sharing or similar distribution-related payments (subject to a $5,000 annual minimum threshold) from the Manager or the Distributor for marketing or program support:

Performance of the Fund

Explanation of Performance Calculations. The use of standardized performance calculations enables an investor to compare the Fund's performance to the performance of other funds for the same periods. The Fund's performance data in advertisements must comply with rules of the SEC, which describe the types of performance data that may be used and how it is to be calculated. In general, any advertisement by the Fund of its performance data must include the average annual total returns for the advertised class of shares of the Fund. The Fund may use a variety of performance calculations, including "cumulative total return," "average annual total return," "average annual total return at net asset value," and "total return at net asset value." How these types of returns are calculated are described below.

A number of factors should be considered before using the Fund's performance information as a basis for comparison with other investments:

• Yields and total returns measure the performance of a hypothetical account in the Fund over various periods and do not show the performance of each shareholder's account. Your account's performance will vary from the model performance data if your dividends are received in cash, or you buy or sell shares during the period, or you bought your shares at a different time and price than the shares used in the model.

• The Fund's performance returns may not reflect the effect of taxes on dividends and capital gains distributions.

• An investment in the Fund is not insured by the FDIC or any other government agency.

• The principal value of the Fund's shares, its yields and total returns are not guaranteed and normally will fluctuate on a daily basis.

• When an investor's shares are redeemed, they may be worth more or less than their original cost.

• Yields and total returns for any given past period represent historical performance information and are not, and should not be considered, a prediction of future yields or returns.

The performance of each class of shares is shown separately, because the performance of each class of shares will usually be different. That is because of the different kinds of expenses each class bears. The yields and total returns of each class of shares of the Fund are affected by market conditions, the quality of the Fund's investments, the maturity of debt investments, the types of investments the Fund holds, and its operating expenses that are allocated to the particular class.

Yields. The Fund uses a variety of different yields to illustrate its current returns. Each class of shares calculates its yield separately because of the different expenses that affect each class.

• Standardized Yield. The "standardized yield" (sometimes referred to just as "yield") is shown for a class of shares for a stated 30-day period. It is not based on actual distributions paid by the Fund to shareholders in the 30-day period, but is a hypothetical yield based upon the net investment income from the Fund's portfolio investments for that period. It may therefore differ from the "dividend yield" for the same class of shares, described below.

Standardized yield is calculated using the following formula set forth in rules adopted by the SEC, designed to assure uniformity in the way that all funds calculate their yields:

The symbols above represent the following factors:

a =dividends and interest earned during the 30-day period.
b =expenses accrued for the period (net of any expense assumptions).
c =the average daily number of shares of that class outstanding during the 30-day period that were entitled to receive dividends.
d =the maximum offering price per share of that class on the last day of the period, adjusted for undistributed net investment income.

The standardized yield for a particular 30-day period may differ from the yield for other periods. The SEC formula assumes that the standardized yield for a 30-day period occurs at a constant rate for a six-month period and is annualized at the end of the six-month period. Additionally, because each class of shares is subject to different expenses, it is likely that the standardized yields of the Fund's classes of shares will differ for any 30-day period.

• Dividend Yield. The Fund may quote a "dividend yield" for each class of its shares. Dividend yield is based on the dividends paid on a class of shares during the actual dividend period. To calculate dividend yield, the dividends of a class declared during a stated period are added together, and the sum is multiplied by 12 (to annualize the yield) and divided by the maximum offering price on the last day of the dividend period. The formula is shown below:

                                       Dividend Yield = dividends paid x 12/maximum offering price (payment date)

The maximum offering price for Class A shares includes the current maximum initial sales charge. The maximum offering price for Class B and Class C shares is the net asset value per share, without considering the effect of contingent deferred sales charges. The Class A dividend yield may also be quoted without deducting the maximum initial sales charge.

• Tax-Equivalent Yield. The "tax-equivalent yield" of a class of shares is the equivalent yield that would have to be earned on a taxable investment to achieve the after-tax results represented by the Fund's tax-equivalent yield. It adjusts the Fund's standardized yield, as calculated above, by a stated tax rate. Using different tax rates to show different tax equivalent yields shows investors in different tax brackets the tax equivalent yield of the Fund based on their own tax bracket.

The tax-equivalent yield is based on a 30-day period, and is computed by dividing the tax-exempt portion of the Fund's current yield (as calculated above) by one minus a stated income tax rate. The result is added to the portion (if any) of the Fund's current yield that is not tax-exempt.

The tax-equivalent yield may be used to compare the tax effects of income derived from the Fund with income from taxable investments at the tax rates stated. Your tax bracket is determined by your federal and state taxable income (the net amount subject to federal and state income tax after deductions and exemptions).

Total Return Information. "Total return" is the change in value of a hypothetical investment in the Fund over a given period, assuming that all dividends and capital gains distributions are reinvested in additional shares and that the investment is redeemed at the end of the period. Because of differences in expenses for each class of shares, the total returns for each class will differ and are measured separately.

There are different types of "total returns." "Cumulative total return" measures the change in value over the entire period (for example, ten years). "Average annual total return" shows the average rate of return for each year in a period that would produce the cumulative total return over the entire period. However, average annual total returns do not show actual year-by-year performance. The Fund uses the methodology prescribed by the SEC to calculate its standardized total returns.

In calculating the Fund's total returns, the following sales charges are applied unless the returns are shown at "net asset value" as described below:

• For Class A shares the current maximum sales charge of 4.75% as a percentage of the offering price is deducted from the initial investment ("P" in the formula below).

• For Class B shares, the CDSC for the applicable period is deducted: 5.0% in the first year, 4.0% in the second year, 3.0% in the third and fourth years, 2.0% in the fifth year, 1.0% in the sixth year and none thereafter.

• For Class C shares, the 1.0% CDSC is deducted for returns for the one-year period.

The Fund's returns are calculated based on the change in value of a hypothetical initial investment of $1,000 ("P" in the formulas below) held for a number of years ("n" in the formulas)

• Average Annual Total Return. The "average annual total return" for each class is an average annual compounded rate of return for each year in a specified number of years that, assuming all dividends and distributions are reinvested, results in an Ending Redeemable Value ("ERV") according to the following formula:

• Average Annual Total Return (After Taxes on Distributions). The "average annual total return (after taxes on distributions)" of Class A shares is an average annual compounded rate of return for each year in a specified number of years that, assuming all dividends and distributions, adjusted to show the effect of federal taxes calculated using the highest individual marginal federal income tax rates in effect on any reinvestment date, are reinvested, results in an ending value ("ATVD") according to the following formula:

• Average Annual Total Return (After Taxes on Distributions and Redemptions). The "average annual total return (after taxes on distributions and redemptions)" of Class A shares is an average annual compounded rate of return for each year in a specified number of years that, assuming all dividends and distributions, adjusted to show the effect of federal taxes calculated using the highest individual marginal federal income tax rates in effect on any reinvestment date, are reinvested, results in an ending value ("ATVDR") after taking into account the effect of capital gains taxes or capital loss tax benefits resulting from the redemption of the shares at the end of the period, each calculated using the highest federal individual capital gains tax rate in effect on the redemption date, according to the following formula:

• Cumulative Total Return. The "cumulative total return" measures the change in value of a hypothetical investment over an entire period of years using some of the same factors as average annual total return, but it does not average the rate of return on an annual basis. Cumulative total return is determined according to the following formula:

• Total Returns at Net Asset Value. From time to time the Fund may also quote cumulative or average annual total returns for Class A, Class B, Class C or Class N shares "at net asset value" without deducting the front-end sales charge or CDSC, based on the difference in net asset value per share at the beginning and, taking into consideration the reinvestment of dividends and capital gains distributions, at the end of the specified period.

• Hypothetical Investment Accounts. Fund advertisements or sales literature may also, from time to time, include performance of a hypothetical investment account that includes the total return of shares of the Fund and other Oppenheimer funds as part of an illustration of an asset allocation model or similar presentation.

A number of factors should be considered before using the Fund's performance information as a basis for comparison with other investments:

• Total returns measure the performance of a hypothetical account in the Fund over various periods and do not show the performance of each shareholder's account. Your account's performance will vary from the model performance data if your dividends are received in cash, or you buy or sell shares during the period, or you bought your shares at a different time and price than the shares used in the model.

• The Fund's performance returns may not reflect the effect of taxes on dividends and capital gains distributions.

• The principal value of the Fund's shares, and total returns are not guaranteed and normally will fluctuate on a daily basis.

• When an investor's shares are redeemed, they may be worth more or less than their original cost.

• An investment in the Fund is not insured by the FDIC or any other government agency.

Performance Data. The charts below show the Fund's performance as of its most recent fiscal year end. You can obtain current performance information by visiting the OppenheimerFunds website at www.oppenheimerfunds.com or by calling the Fund's Transfer Agent at the telephone number shown on the cover of this SAI.

The performance of each class of shares is shown separately, because the performance of each class of shares will usually be different. That is because of the different kinds of expenses each class bears. The total returns of each class of shares of the Fund are affected by market conditions, the quality of the Fund's investments, the maturity of those investments, the types of investments the Fund holds, and its operating expenses that are allocated to the particular class.

Total returns for any given past period represent historical performance information and are not, and should not be considered, a prediction of future returns.

Other Performance Comparisons. In its Annual Report to shareholders, the Fund compares its performance to that of one or more appropriate market indices. You can obtain that information by visiting the OppenheimerFunds website at www.oppenheimerfunds.com or by calling the Fund's Transfer Agent at the telephone number shown on the cover of this SAI. The Fund may also compare its performance to that of other investments, including other mutual funds, or use rankings of its performance by independent ranking entities. The following are examples of some of those comparisons.

     Lipper Rankings. From time to time the Fund may publish the ranking of the performance of its share classes by Lipper, Inc. ("Lipper"), a widely-recognized independent mutual fund monitoring service. Lipper monitors and ranks the performance of regulated investment companies for various periods in categories based on investment styles. Lipper also publishes "peer-group" indices and averages of the performance of all mutual funds in particular categories.

     Morningstar Ratings. From time to time the Fund may publish the "star ratings" of its classes of shares by Morningstar, Inc. ("Morningstar"), an independent mutual fund monitoring service that rates and ranks mutual funds within their specialized market sectors. Morningstar proprietary star ratings reflect risk-adjusted historical total investment returns for funds with at least a three-year performance history. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star.

     Performance Rankings and Comparisons by Other Entities and Publications. From time to time the Fund may include in its advertisements and sales literature performance information about the Fund cited in newspapers and other periodicals such as The New York Times, The Wall Street Journal, Barron's or other similar publications. That information may include performance quotations from other sources, including Lipper and Morningstar or the Fund's performance may be compared to the performance of various market indices, other investments, or averages, performance rankings or other benchmarks prepared by recognized mutual fund statistical services. The Fund's advertisements and sales literature may also include, for illustrative or comparative purposes, statistical data or other information about general or specific market and economic conditions, for example:

• information about the performance of certain securities or commodities markets or segments of those markets,

• information about the performance of the economies of particular countries or regions,

• the earnings of companies included in segments of particular industries, sectors, securities markets, countries or regions,

• the availability of different types of securities or offerings of securities,

• information relating to the gross national or gross domestic product of the United States or other countries or regions,

• comparisons of various market sectors or indices to demonstrate performance, risk, or other characteristics of the Fund.

From time to time, the Fund may publish rankings or ratings of the Manager or Transfer Agent by third parties, including comparisons of investor services provided to shareholders of the Oppenheimer funds to those provided by other mutual fund families selected by the rating or ranking services. Those comparisons may be based on the opinions of the rating or ranking service itself, using its research or judgment, or may be based on surveys of investors, brokers, shareholders or others.

Investors may also wish to compare the returns on the Fund's share classes to the return on fixed-income investments available from banks and thrift institutions, including certificates of deposit, ordinary interest-paying checking and savings accounts, and other forms of fixed or variable time deposits or instruments such as Treasury bills. However, the Fund's returns and share price are not guaranteed or insured by the FDIC or any other agency and will fluctuate daily, while bank depository obligations may be insured by the FDIC and may provide fixed rates of return. Repayment of principal and payment of interest on Treasury securities is backed by the full faith and credit of the U.S. Government.

About Your Account

The Fund's Prospectus describes how to buy, sell and exchange shares of the Fund and certain other Oppenheimer funds. The information below provides further details about the Fund's policies regarding those share transactions. It should be read in conjunction with the information in the Prospectus. Appendix A of this SAI provides more information about the special sales charge arrangements offered by the Fund, and the circumstances in which sales charges may be reduced or waived for certain investors and certain types of purchases or redemptions.

Determination of Net Asset Value Per Share. The net asset value ("NAV") per share for each class of shares of the Fund is determined by dividing the value of the Fund's net assets attributable to a class by the number of shares of that class that are outstanding. The NAV is determined as of the close of business on the New York Stock Exchange ("NYSE") on each day that the NYSE is open. The NYSE normally closes at 4:00 p.m., Eastern time, but may close earlier on some other days (for example, in case of weather emergencies or on days falling before a U.S. holiday). All references to time in this SAI mean "Eastern time." The NYSE's most recent annual announcement (which is subject to change) states that it will close on New Year's Day, Martin Luther King, Jr. Day, Washington's Birthday (Presidents Day), Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. It may also close on other days.

Dealers other than NYSE members may conduct trading in municipal securities on days that the NYSE is closed (including weekends and holidays) or after 4:00 p.m. on a regular business day. Because the Fund's net asset values will not be calculated on those days, the Fund's net asset values per share may be significantly affected on days when shareholders may not purchase or redeem shares.

Securities Valuation. The Fund's Board has established procedures for the valuation of the Fund's securities. In general those procedures are as follows:

• Long-term debt securities having a remaining maturity of more than 60 days are valued based on the mean between the "bid" and "asked" prices determined by a portfolio pricing service approved by the Fund's Board or obtained by the Manager from two active market makers in the security on the basis of reasonable inquiry.

• The following securities are valued at the mean between the "bid" and "asked" prices determined by a pricing service approved by the Fund's Board or obtained by the Manager from two active market makers in the security on the basis of reasonable inquiry:

1. debt instruments that have a maturity of more than 397 days when issued,
2. debt instruments that had a maturity of 397 days or less when issued and have a remaining maturity of more than 60 days, and
3. non-money market debt instruments that had a maturity of 397 days or less when issued and which have a remaining maturity of 60 days or less.

• The following securities are valued at cost, adjusted for amortization of premiums and accretion of discounts:

1. money market debt securities held by a non-money market fund that had a maturity of less than 397 days when issued and that have a remaining maturity of 60 days or less, and
2. debt instruments held by a money market fund that have a remaining maturity of 397 days or less.

• Securities not having readily-available market quotations are valued at fair value determined under the Board's procedures. If the Manager is unable to locate two market makers willing to give quotes, a security may be priced at the mean between the "bid" and "asked" prices provided by a single active market maker, or the "bid" price if no "asked" price is available.

In the case of municipal securities the Manager uses pricing services approved by the Board. The pricing service may use "matrix" comparisons to the prices for comparable instruments on the basis of quality, yield and maturity. Other special factors may be involved (such as the tax-exempt status of the interest paid by municipal securities). The Manager will monitor the accuracy of the pricing services valuations. That monitoring may include comparing prices used for portfolio valuation to the actual sale prices of selected securities.

Puts, calls, futures and municipal bond index futures are valued at the last sale price on the principal exchange on which they are traded, as determined by a pricing service approved by the Board or by the Manager.

Allocation of Expenses. The Fund pays expenses related to its daily operations, such as custodian fees, Board fees, transfer agency fees, legal fees and auditing costs. Those expenses are paid out of the Fund's assets, not directly by shareholders. However, those expenses reduce the net asset value of Fund shares, and therefore are borne indirectly by shareholders.

For calculating the Fund's net asset value, dividends and distributions, the Fund differentiates between two types of expenses. General expenses that do not pertain specifically to any one class are allocated pro rata to the shares of all classes. Those expenses are first allocated based on the percentage of the Fund's total assets that is represented by the assets of each share class. Such general expenses include management fees, legal, bookkeeping and audit fees, Board compensation, custodian expenses, share issuance costs, interest, taxes, brokerage commissions, and non-recurring expenses, such as litigation costs. Then the expenses allocated to a share class are allotted equally to each outstanding share within a given class.

Other expenses that are directly attributable to a particular class are allocated equally to each outstanding share within that class. Examples of such expenses include distribution and service plan (12b-1) fees, transfer and shareholder servicing agent fees and expenses, and shareholder meeting expenses to the extent that such expenses pertain only to a specific class.

Classes of Shares. Each class of shares of the Fund represents an interest in the same portfolio of investments of the Fund. However, each class has different shareholder privileges and features. The net income attributable to Class B or Class C shares and the dividends payable on Class B or Class C shares will be reduced by incremental expenses borne solely by that class. Those expenses include the asset-based sales charges to which Class B and Class C shares are subject.

The availability of different classes of shares permits an investor to choose the method of purchasing shares that is more appropriate for the investor. That may depend on the amount of the purchase, the length of time the investor expects to hold shares, and other relevant circumstances. Class A shares normally are sold subject to an initial sales charge. While Class B and Class C shares have no initial sales charge, the purpose of the deferred sales charge and asset-based sales charge on Class B and Class C shares is the same as that of the initial sales charge on Class A shares – to compensate the Distributor and brokers, dealers and financial institutions that sell shares of the Fund. A salesperson who is entitled to receive compensation from his or her firm for selling Fund shares may receive different levels of compensation for selling one class of shares rather than another.

The Distributor will not accept a purchase order of more than $100,000 for Class B shares or a purchase order of $1 million or more to purchase Class C shares on behalf of a single investor (not including dealer "street name" or omnibus accounts).

Class B or Class C shares may not be purchased by a new investor directly from the Distributor without the investor designating another registered broker-dealer.

Class A Sales Charges Reductions and Waivers. There is an initial sales charge on the purchase of Class A shares of each of the Oppenheimer funds except for the money market funds (under certain circumstances described in this SAI, redemption proceeds of certain money market fund shares may be subject to a CDSC). As discussed in the Prospectus, a reduced initial sales charge rate may be obtained for certain share purchases because of the reduced sales efforts and reduction in expenses realized by the Distributor, dealers or brokers in making such sales. Sales charge waivers may apply in certain other circumstances because the Distributor or dealer or broker incurs little or no selling expenses. Appendix A to this SAI includes additional information regarding certain of these sales charge reductions and waivers.

A reduced sales charge rate may be obtained for Class A shares under a Right of Accumulation or Letter of Intent because of the reduction in sales effort and expenses to the Distributor, dealers or brokers for those sales.

Letter of Intent. Under a Letter of Intent (a "Letter"), you may be able to reduce the initial sales charge rate that applies to your Class A share purchases of the Fund if you purchase Class A, Class B or Class C shares of the Fund or other Oppenheimer funds or Class A, Class B, Class C, Class G and Class H units of advisor sold Section 529 plans, for which the Manager or the Distributor serves as the Program Manager or Program Distributor.

A Letter is an investor's statement in writing to the Distributor of his or her intention to purchase a specified value of those shares or units during a 13 month period (the "Letter period"), which begins on the date of the investor's first share purchase following the establishment of the Letter. The sales charge on each purchase of Class A shares during the Letter period will be at the rate that would apply to a single lump-sum purchase of shares in the amount intended to be purchased. In submitting a Letter, the investor makes no commitment to purchase shares. However, if the investor does not fulfill the terms of the Letter within the Letter period, he or she agrees to pay the additional sales charges that would have been applicable to any purchases that are made. The investor agrees that shares equal in value to 2% of the intended purchase amount will be held in escrow by the Transfer Agent for that purpose, as described in "Terms of Escrow" below. It is the responsibility of the dealer of record and/or the investor to advise the Distributor about the Letter when placing purchase orders during the Letter period. The investor must also notify the Distributor or his or her financial intermediary of any qualifying 529 plan holdings.

To determine whether an investor has fulfilled the terms of a Letter, the Transfer Agent will count purchases of "qualified" Class A, Class B and Class C shares and Class A, Class B, Class C, Class G and Class H units during the Letter period. Purchases of Class N or Class Y shares, purchases made by reinvestment of dividends or capital gains distributions from the Fund or other Oppenheimer funds, purchases of Class A shares with redemption proceeds under the Reinvestment Privilege, and purchases of Class A shares of Oppenheimer Money Market Fund, Inc. or Oppenheimer Cash Reserves on which a sales charge has not been paid do not count as "qualified" shares for satisfying the terms of a Letter. An investor will also be considered to have fulfilled the Letter if the value of the investor's total holdings of qualified shares on the last day of the Letter period equals or exceeds the intended purchase amount.

If the terms of the Letter are not fulfilled within the Letter period, the concessions previously paid to the dealer of record for the account and the amount of sales charge retained by the Distributor will be adjusted on the first business day following the expiration of the Letter period to reflect the sales charge rates that are applicable to the actual total purchases.

If total eligible purchases during the Letter period exceed the intended purchase amount and also exceed the amount needed to qualify for the next sales charge rate reduction (stated in the Prospectus), the sales charges paid may be adjusted to that lower rate. That adjustment will only be made if and when the dealer returns to the Distributor the amount of the excess concessions allowed or paid to the dealer over the amount of concessions that are applicable to the actual amount of purchases. The reduced sales charge adjustment will be made by adding to the investors account the number of additional shares that would have been purchased if the lower sales charge rate had been used. Those additional shares will be determined using the net asset value per share in effect on the date of such adjustment.

By establishing a Letter, the investor agrees to be bound by the terms of the Prospectus, this SAI and the application used for a Letter, and if those terms are amended to be bound by the amended terms and that any amendments by the Fund will apply automatically to existing Letters. Group retirement plans qualified under section 401(a) of the Internal Revenue Code may not establish a Letter, however defined benefit plans and Single K sole proprietor plans may do so.

Terms of Escrow That Apply to Letters of Intent.

1. Out of the initial purchase, or out of subsequent purchases if necessary, the Transfer Agent will hold in escrow Fund shares equal to 2% of the intended purchase amount specified in the Letter. For example, if the intended purchase amount is $50,000, the escrow amount would be shares valued at $1,000 (computed at the offering price for a $50,000 share purchase). Any dividends and capital gains distributions on the escrowed shares will be credited to the investor's account.

 2. If the Letter applies to more than one fund account, the investor can designate the fund from which shares will be escrowed. If no fund is selected, the Transfer Agent will escrow shares in the fund account that has the highest dollar balance on the date of the first purchase under the Letter. If there are not sufficient shares to cover the escrow amount, the Transfer Agent will escrow shares in the fund account(s) with the next highest balance(s). If there are not sufficient shares in the accounts to which the Letter applies, the Transfer Agent may escrow shares in other accounts that are linked for Right of Accumulation purposes. Additionally, if there are not sufficient shares available for escrow at the time of the first purchase under the Letter, the Transfer Agent will escrow future purchases until the escrow amount is met.

3. If, during the Letter period, an investor exchanges shares of the Fund for shares of another fund (as described in the Prospectus section titled "The OppenheimerFunds Exchange Privilege"), the Fund shares held in escrow will automatically be exchanged for shares of the other fund and the escrow obligations will also be transferred to that fund.

4. If the total purchases under the Letter are less than the intended purchases specified, on the first business day after the end of the Letter period, the Distributor will redeem escrowed shares equal in value to the difference between the dollar amount of the sales charges actually paid and the amount of the sales charges that would have been paid if the total purchases had been made at a single time. Any shares remaining after such redemption will be released from escrow.

5. If the terms of the Letter are fulfilled, the escrowed shares will be promptly released to the investor at the end of the Letter period.

6. By signing the Letter, the investor irrevocably constitutes and appoints the Transfer Agent as attorney-in-fact to surrender for redemption any or all escrowed shares.

Share Certificates. When you purchase shares of the Fund, your ownership interest in the shares of the Fund will be recorded as a book entry on the records of the Fund. The Fund will not issue or re-register physical share certificates.

Cancellation of Purchase Orders. Cancellation of purchase orders for the Fund's shares (for example, when a purchase check is returned to the Fund unpaid) causes a loss to be incurred when the net asset values of the Fund's shares on the cancellation date is less than on the purchase date. That loss is equal to the amount of the decline in the net asset value per share multiplied by the number of shares in the purchase order. The investor is responsible for that loss. If the investor fails to compensate the Fund for the loss, the Distributor will do so. The Fund may reimburse the Distributor for that amount by redeeming shares from any account registered in that investor's name, or the Fund or the Distributor may seek other redress.

AccountLink. Shares purchased through AccountLink will be purchased at the net asset value calculated on the same regular business day if the Distributor is instructed to initiate the Automated Clearing House ("ACH") transfer to buy the shares before the close of the NYSE. The NYSE normally closes at 4:00 p.m., but may close earlier on certain days. If the Distributor is instructed to initiate the ACH transfer after the close of the NYSE, the shares will be purchased on the next regular business day.

Dividends will begin to accrue on the shares purchased through the ACH system on the business day the Fund receives Federal Funds before the close of the NYSE. The proceeds of ACH transfers are normally received by the Fund three days after a transfer is initiated. If Federal Funds are received on a business day after the close of the NYSE, dividends will begin to accrue on the next regular business day. If the proceeds of an ACH transfer are not received on a timely basis, the Distributor reserves the right to cancel the purchase order. The Distributor and the Fund are not responsible for any delays in purchasing shares resulting from delays in ACH transmissions.

The minimum purchase through AccountLink is generally $50, however for accounts established prior to November 1, 2002 the minimum purchase is $25.

Asset Builder Plans. As indicated in the Prospectus, you normally must establish your Fund account with $1,000 or more. However, you can open a Fund account for as little as $500 if you establish an Asset Builder Plan at the time of your initial share purchase to automatically purchase additional shares directly from a bank account.

An Asset Builder Plan is available only if your bank is an ACH member and you establish AccountLink. Under an Asset Builder Plan, payments to purchase shares of the Fund will be debited from your bank account automatically. Normally the debit will be made two business days prior to the investment dates you select on your application. Neither the Distributor, the Transfer Agent nor the Fund will be responsible for any delays in purchasing shares that result from delays in ACH transmissions.

To establish an Asset Builder Plan at the time you initially purchase Fund shares, complete the "Asset Builder Plan" information on the Account Application. To establish an Asset Builder Plan for an existing account, use the Asset Builder Enrollment Form. The Account Application and the Asset Builder Enrollment Form are available by contacting the Distributor or may be downloaded from our website at www.oppenheimerfunds.com. Before you establish a new Fund account under the Asset Builder Plan, you should obtain a prospectus of the selected Fund and read it carefully.

You may change the amount of your Asset Builder payment or you can terminate your automatic investments at any time by writing to the Transfer Agent. The Transfer Agent requires a reasonable period (approximately 10 days) after receipt of your instructions to implement them. The minimum additional purchase under an Asset Builder Plan is $50, except that for Asset Builder Plans established prior to November 1, 2002, the minimum additional purchase is $25. Shares purchased by Asset Builder Plan payments are subject to the redemption restrictions for recent purchases described in the Prospectus. An Asset Builder Plan may not be used to buy shares for OppenheimerFunds employer-sponsored qualified retirement accounts. The Fund reserves the right to amend, suspend or discontinue offering Asset Builder Plans at any time without prior notice.

How to Sell Shares

Receiving Redemption Proceeds by Federal Funds Wire. The Fund would normally authorize a Federal Funds wire of redemption proceeds to be made on its next regular business day following the redemption. A Federal Funds wire may be delayed if the Fund's custodian bank is not open for business on that day. In that case, the wire will not be transmitted until the next business day on which the bank and the Fund are both open for business. No dividends will be paid on the proceeds of redeemed shares awaiting transfer by Federal Funds wire.

Redeeming Shares Through Brokers or Dealers. The Distributor is the Fund's agent to repurchase its shares from authorized brokers or dealers on behalf of their customers. Shareholders should contact their broker or dealer to arrange this type of redemption. The repurchase price per share will be the next net asset value computed after the Distributor or the broker or dealer receives the order. A repurchase will be processed at that day's net asset value if the order was received by the broker or dealer from its customer prior to the time the close of the NYSE. Normally, the NYSE closes at 4:00 p.m., but may do so earlier on some days.

For accounts redeemed through a broker-dealer, payment will ordinarily be made within three business days after the shares are redeemed. However, the Distributor must receive the required redemption documents in proper form, with the signature(s) of the registered shareholder(s) guaranteed as described in the Prospectus.

Payments "In Kind." As stated in the Prospectus, payment for redeemed shares is ordinarily made in cash. Under certain circumstances, however, the Board may determine that it would be detrimental to the best interests of the remaining shareholders for the Fund to pay for the redeemed shares in cash. In that case, the Fund may pay the redemption proceeds, in whole or in part, by a distribution "in kind" of liquid securities from the Fund's portfolio. The Fund will value securities used to pay a redemption in kind using the same method described above under "Determination of Net Asset Value Per Share." That valuation will be made as of the time the redemption price is determined. If shares are redeemed in kind, the redeeming shareholder might incur brokerage or other costs in selling the securities for cash.

The Fund has elected to be governed by Rule 18f-1 under the Investment Company Act. Under that rule, redemptions by a shareholder, of up to the lesser of $250,000 or 1% of the net assets of the Fund during any 90-day period, must be redeemed solely in cash.

Automatic Withdrawal Plans. Under an Automatic Withdrawal Plan, investors who own Fund shares can authorize the Transfer Agent to redeem shares automatically on a monthly, quarterly, semi-annual or annual basis. The minimum periodic redemption amount under an Automatic Withdrawal Plan is $50. Shareholders having AccountLink privileges may have Automatic Withdrawal Plan payments deposited to their designated bank account. Payments may also be made by check, payable to all shareholders of record and sent to the address of record for the account. Automatic withdrawals may be requested by telephone for amounts up to $1,500 per month if the payments are to be made by checks sent to the address of record for the account. Telephone requests are not available if the address on the account has been changed within the prior 15 days.

Fund shares will be redeemed as necessary to meet the requested withdrawal payments. Shares will be redeemed at the net asset value per share determined on the redemption date, which is normally three business days prior to the payment receipt date requested by the shareholder. The Fund cannot guarantee receipt of a payment on the date requested, however. Shares acquired without a sales charge will be redeemed first. Shares acquired with reinvested dividends and capital gains distributions will be redeemed next, followed by shares acquired with a sales charge, to the extent necessary to make withdrawal payments. Depending on the amount withdrawn, the investor's principal may be depleted. Payments made under these plans should not be considered as a yield or income on your investment.

Because of the sales charge assessed on Class A share purchases, shareholders should usually not make additional Class A share purchases while participating in an Automatic Withdrawal Plan. A shareholder whose Class B, Class C or Class N account is subject to a CDSC should usually not establish an automatic withdrawal plan because of the imposition of the CDSC on the withdrawals. If a CDSC does apply to a redemption, the amount of the check or payment will be reduced accordingly. Distributions of capital gains from accounts subject to an Automatic Withdrawal Plan must be reinvested in Fund shares. Dividends on shares held in the account may be paid in cash or reinvested. Required minimum distributions from OppenheimerFunds-sponsored retirement plans may not be arranged on this basis.

The shareholder may change the amount, the payment interval, the address to which checks are to be mailed, the designated bank account for AccountLink payments or may terminate a plan at any time by writing to the Transfer Agent. A signature guarantee may be required for certain changes. The requested change will usually be put into effect approximately two weeks after such notification is received. The shareholder may redeem all or any part of the shares in the account by written notice to the Transfer Agent. That notice must be in proper form in accordance with the requirements in the then-current Fund Prospectus.

The Transfer Agent will administer the Automatic Withdrawal Plan as agent for the shareholder(s) who executed the plan authorization and application submitted to the Transfer Agent. Neither the Fund nor the Transfer Agent shall incur any liability for any action taken or not taken by the Transfer Agent in good faith to administer the plan. Any share certificates must be surrendered unendorsed to the Transfer Agent with the plan application to be eligible for automatic withdrawal payments. If the Transfer Agent ceases to act as transfer agent for the Fund, the shareholder will be deemed to have appointed any successor transfer agent to act as agent in administering the plan.

The Transfer Agent will terminate a plan upon its receipt of evidence, satisfactory to it, that the shareholder has died or is legally incapacitated. The Fund may also give directions to the Transfer Agent to terminate a plan. Shares that have not been redeemed at the time a plan is terminated will be held in an account in the name of the shareholder. Share certificates will not be issued for any such shares and all dividends will be reinvested in the account unless and until different instructions are received, in proper form, from the shareholder, his or her executor or guardian, or another authorized person.

The Fund reserves the right to amend, suspend or discontinue offering these plans at any time without prior notice. By requesting an Automatic Withdrawal Plan, the shareholder agrees to the terms and conditions that apply to such plans. These provisions may be amended from time to time by the Fund and/or the Distributor. When adopted, any amendments will automatically apply to existing Plans.

Transfers of Shares. A shareholder will not be required to pay a CDSC when Fund shares are transferred to registration in the name of another person or entity. The transfer may occur by absolute assignment, gift or bequest, as long as it does not involve, directly or indirectly, a public sale of the shares. When shares subject to a CDSC are transferred, the CDSC will continue to apply to the transferred shares and will be calculated as if the transferee had acquired the shares in the same manner and at the same time as the transferring shareholder.

If less than all of the shares held in an account are transferred, and some but not all shares in the account would be subject to a CDSC if redeemed at that time, the priorities for the imposition of the CDSC described in the Prospectus will be followed in determining the order in which the shares are transferred.

Minimum Balance Fee. As stated in the Prospectus, a $12 annual "Minimum Balance Fee" is assessed on each Fund account with a share balance of less than $500. The Minimum Balance Fee is automatically deducted from each such Fund account in September.

Listed below are certain cases in which the Fund has elected, in its discretion, not to assess the Minimum Balance Fee. These exceptions are subject to change:

• A fund account whose shares were acquired after September 30th of the prior year;

• A fund account that has a balance below $500 due to the automatic conversion of shares from Class B to Class A shares. However, once all Class B shares held in the account have been converted to Class A shares the new Class A share account balance may become subject to the Minimum Balance Fee;

• Accounts of shareholders who elect to access their account documents electronically via eDoc Direct (to access account documents electronically via eDocs Direct, please visit our website at www.oppenheimerfunds.com and click the hyperlink "Sign Up for Electronic Document Delivery (eDocs Direct)" under the heading "I Want To," or call 1.888.470.0862 for instructions);

• A fund account that has only certificated shares and, has a balance below $500 and is being escheated;

• Accounts of shareholders that are held by broker-dealers under the NSCC Fund/SERV system in Networking level 1 and 3 accounts;

• Accounts held under the Oppenheimer Legacy Program and/or holding certain Oppenheimer Variable Account Funds;

• Omnibus accounts holding shares pursuant to the Pinnacle, Ascender, Custom Plus, Recordkeeper Pro and Pension Alliance Retirement Plan programs;

• A fund account that falls below the $500 minimum solely due to market fluctuations within the 12-month period preceding the date the fee is deducted; and

• Accounts held in the OppenheimerFunds Portfolio Builder Program which is offered through certain broker/dealers to qualifying shareholders.

Unclaimed accounts may be subject to state escheatment laws, and the Fund and the Transfer Agent will not be liable to shareholders or their representatives for good faith compliance with those laws.

The Fund reserves the authority to modify Minimum Balance Fee in its discretion.

Involuntary Redemptions. The Fund's Board has the right to involuntarily redeem shares held in any account with an aggregate net asset value of less than $200. The Board may change the amount of the aggregate net asset value to which an involuntary redemption may apply. The Board will not cause the involuntary redemption of shares in an account if the aggregate net asset value of such shares has fallen below the stated minimum solely as a result of market fluctuations. If the Board exercises this right, it may also determine the requirements for any notice to be given to the shareholders (but not less than 30 days). Alternatively, the Board may set requirements for the shareholder to increase the investment, or set other terms and conditions so that the shares would not be involuntarily redeemed.

Reinvestment Privilege. Within six months after redeeming Class A or Class B shares, a shareholder may reinvest all or part of the redemption proceeds without a sales charge if:

• An initial sales charge was paid on the redeemed Class A shares or a Class A CDSC was paid when the shares were redeemed; or

• The Class B CDSC was paid on the redeemed Class B shares.

The reinvestment may only be made in Class A shares of the Fund or other Oppenheimer funds into which shares of the Fund are exchangeable, as described in "How to Exchange Shares" below. This privilege does not apply to Class C shares or to purchases made through automatic investment options. The Fund may amend, suspend or cease offering this reinvestment privilege at any time for shares redeemed after the date of the amendment, suspension or cessation. The shareholder must request the reinvestment privilege from the Transfer Agent or his or her financial intermediary at the time of purchase.

Reinvestment will be at the next net asset value computed after the Transfer Agent receives the reinvestment order. Any capital gain that was realized when the shares were redeemed is taxable, and reinvestment will not alter any capital gains tax payable on that gain. If there was a capital loss on the redemption, some or all of the loss may not be tax deductible, depending on the timing and amount of the reinvestment. Under the Internal Revenue Code, if the redemption proceeds of Fund shares on which a sales charge was paid are reinvested in shares of the Fund or another of the Oppenheimer funds within 90 days after the payment of the sales charge, the shareholder's basis in the shares of the Fund that were redeemed may not include the amount of the sales charge paid. That would reduce the loss or increase the gain recognized from the redemption, however, the sales charge would be added to the basis of the shares acquired with the redemption proceeds.

How to Exchange Shares

Shares of the Fund (including shares acquired by reinvestment of dividends or distributions from other Oppenheimer funds or from a unit investment trust) may be exchanged for shares of certain other Oppenheimer funds at net asset value without the imposition of a sales charge, however a CDSC may apply to the acquired shares as described below. Shares of certain money market funds purchased without a sales charge may be exchanged for shares of other Oppenheimer funds offered with a sales charge upon payment of the sales charge. Exchanges into another Oppenheimer fund must meet any applicable minimum investment requirements of that fund.

As stated in the Prospectus, shares of a particular class of Oppenheimer funds having more than one class of shares may be exchanged only for shares of the same class of other Oppenheimer funds. The prospectus of each of the Oppenheimer funds indicates which share class or classes that fund offers and provides information about limitations on the purchase of particular share classes, as applicable for the particular fund. Shareholders that own more than one class of shares of the Fund must specify which class of shares they wish to exchange.

You can obtain a current list of the share classes offered by the funds by calling the toll-free phone number on the first page of this SAI.

The different Oppenheimer funds that are available for exchange have different investment objectives, policies and risks. A shareholder should determine whether the fund selected is appropriate for his or her investment goals and should be aware of the tax consequences of an exchange. For federal income tax purposes, an exchange transaction is treated as a redemption of shares of one fund and a purchase of shares of another. Some of the tax consequences of reinvesting redemption proceeds are discussed in "Reinvestment Privilege," above. The Fund, the Distributor, and the Transfer Agent are unable to provide investment, tax or legal advice to a shareholder in connection with an exchange request or any other investment transaction.

The Fund may amend, suspend or terminate the exchange privilege at any time. Although the Fund may impose these changes at any time, it will provide notice of those changes whenever it is required to do so by applicable law. It may be required to provide 60 days' notice prior to materially amending or terminating the exchange privilege, however that notice is not required in extraordinary circumstances.

How Exchanges Affect Contingent Deferred Sales Charges. A CDSC is imposed on exchanges of shares in the following cases:

• The Class A CDSC is imposed on the redemption of Class A shares acquired by the exchange of Class A shares that are subject to a Class A CDSC, if the acquired shares are redeemed within 18 months measured from the beginning of the calendar month in which the exchanged Class A shares were purchased.

• The Class A CDSC is imposed on the redemption of Class A shares of Oppenheimer Rochester National Municipals and Rochester Fund Municipals acquired prior to October 22, 2007 by the exchange of Class A shares that are subject to a Class A CDSC, if the acquired shares are redeemed within 24 months measured from the beginning of the calendar month in which the exchanged Class A shares were purchased.

• An Early Withdrawal Charge is imposed on Class A shares of Oppenheimer Senior Floating Rate Fund acquired by the exchange of Class A shares that are subject to a CDSC, if the acquired shares are repurchased before the expiration of the holding period that was applicable to the exchanged shares.

• The Class A CDSC is imposed on the redemption of Class A shares of Oppenheimer Cash Reserves and Oppenheimer Money Market Fund, Inc. acquired by the exchange of Class A shares that are subject to a Class A CDSC, if the acquired shares are redeemed within the holding period applicable to the exchanged Class A shares.

• The Class B CDSC is imposed on Class B shares acquired by exchange if they are redeemed within six years of the initial purchase of the exchanged shares, except:

(1)With respect to Class B shares of Oppenheimer Limited Term California Municipal Fund, Oppenheimer Limited-Term Government Fund, Oppenheimer Limited Term Municipal Fund, Limited Term New York Municipal Fund and Oppenheimer Senior Floating Rate Fund acquired by exchange, the Class B CDSC is imposed on the acquired shares if they are redeemed within five years of the initial purchase of the exchanged Class B shares.

(2)With respect to Class B shares of Oppenheimer Cash Reserves acquired by the exchange of Class B shares of Oppenheimer Capital Preservation Fund, the Class B CDSC is imposed on the acquired shares if they are redeemed within five years of the initial purchase of the exchanged Class B shares.

• The Class C CDSC is imposed on Class C shares acquired by exchange if they are redeemed within 12 months of the initial purchase of the exchanged shares.

When Class B or Class C shares are exchanged, the priorities for the imposition of the CDSC described in "How To Buy Shares" in the Prospectus will be followed in determining the order in which the shares are exchanged. Before exchanging shares, shareholders should consider how the exchange may affect any CDSC that might be imposed on the subsequent redemption of remaining shares.

Telephone Exchange Requests. When exchanging shares by telephone, a shareholder must have an existing account in the fund to which the exchange is to be made. Otherwise, the investors must obtain a prospectus of that fund before the exchange request may be submitted. If all telephone lines are busy (which might occur, for example, during periods of substantial market fluctuations), shareholders might not be able to request exchanges by telephone and would have to submit written exchange requests.

Automatic Exchange Plans. Under an Automatic Exchange Plan, shareholders can authorize the Transfer Agent to exchange shares of the Fund for shares of other Oppenheimer funds automatically on a monthly, quarterly, semi-annual or annual basis. The minimum amount that may be exchanged to each other fund account is $50. Instructions regarding the exchange amount, the selected fund(s) and the exchange interval should be provided on the OppenheimerFunds account application or by signature-guaranteed instructions. Any requested changes will usually be put into effect approximately two weeks after notification of a change is received. Exchanges made under these plans are subject to the restrictions that apply to exchanges as set forth in this SAI and in "The OppenheimerFunds Exchange Privilege" in the Prospectus.

The Transfer Agent will administer the Automatic Exchange Plan as agent for the shareholder(s). Neither the Fund nor the Transfer Agent shall incur any liability for any action taken or not taken by the Transfer Agent in good faith to administer the plan. Any share certificates must be surrendered unendorsed to the Transfer Agent with the plan application to be eligible for automatic exchanges. If the Transfer Agent ceases to act as transfer agent for the Fund, the shareholder will be deemed to have appointed any successor transfer agent to act as agent in administering the plan.

The Fund reserves the right to amend, suspend or discontinue offering automatic exchanges at any time without prior notice. By requesting an Automatic Exchange Plan, the shareholder agrees to the terms and conditions that apply to such plans. These provisions may be amended from time to time and any amendments will automatically apply to existing Plans.

Processing Exchange Requests. Shares to be exchanged are redeemed at the net asset value calculated on the regular business day the Transfer Agent receives an exchange request in proper form before the close of the NYSE (the "Redemption Date"). Normally, shares of the fund to be acquired are purchased on the Redemption Date, but such purchases may be delayed by up to five business days if it is determined that either fund would be disadvantaged by an immediate transfer of the redemption proceeds. The Fund reserves the right, in its discretion, to refuse any exchange request that may disadvantage it. For example, if the receipt of multiple exchange requests from a dealer might require the disposition of portfolio securities at a time or at a price that might be disadvantageous to the Fund, the Fund may refuse the request.

When you exchange some or all of your shares, any special features of your account that are available in the new fund (such as an Asset Builder Plan or Automatic Withdrawal Plan) will be applied to the new fund account unless you tell the Transfer Agent not to do so.

Shares that are subject to a restriction cited in the Prospectus or this SAI and shares covered by a share certificate that is not tendered will not be exchanged. If an exchange request includes such shares, only the shares available without restrictions will be exchanged.

Distributions and Taxes

Dividends and Other Distributions. Dividends will be payable on shares held of record at the time of the previous determination of net asset value, or as otherwise described in "How to Buy Shares." Daily dividends will not be declared or paid on newly purchased shares until such time as Federal Funds (funds credited to a member bank's account at the Federal Reserve Bank) are available from the purchase payment for such shares. Normally, purchase checks received from investors are converted to Federal Funds on the next business day. Shares purchased through dealers or brokers normally are paid for by the third business day following the placement of the purchase order.

Shares redeemed through the regular redemption procedure will be paid dividends through and including the day on which the redemption request is received by the Transfer Agent in proper form. Dividends will be declared on shares repurchased by a dealer or broker for three business days following the trade date (that is, up to and including the day prior to settlement of the repurchase). If all shares in an account are redeemed, all dividends accrued on shares of the same class in the account will be paid together with the redemption proceeds.

The Fund's practice of attempting to pay dividends on Class A shares at a constant level requires the Manager to monitor the Fund's portfolio and, if necessary, to select higher-yielding securities when it is deemed appropriate to seek income at the level needed to meet the target. Those securities must be within the Fund's investment parameters, however. The Fund expects to pay dividends at a targeted level from its net investment income and other distributable income without any impact on the net asset values per share.

The distributions made by the Fund will vary depending on market conditions, the composition of the Fund's portfolio and Fund expenses.  Distributions are calculated in the same manner, at the same time, and on the same day for each class of shares but will normally differ in amount. Distributions on Class B and Class C shares are expected to be lower than distributions on Class A shares and Class Y shares (if applicable) because of the effect of the asset-based sales charge on Class B and Class C shares. Whether they are reinvested in Fund shares or received in cash, distributions are taxable to shareholders, as discussed below, regardless of whether the distributions are paid in cash or reinvested in additional shares of the Fund (or of another fund). Shareholders receiving a distribution in the form of additional shares will be treated as receiving a distribution in an amount equal to the fair market value of the shares received, determined as of the reinvestment date.

Returned checks for the proceeds of redemptions are invested in shares of Oppenheimer Money Market Fund, Inc. If a dividend check or a check representing an automatic withdrawal payment is returned to the Transfer Agent by the Postal Service as undeliverable, it will be reinvested in shares of the Fund. Reinvestments will be made as promptly as possible after the return of such checks to the Transfer Agent. Unclaimed accounts may be subject to state escheatment laws, and the Fund and the Transfer Agent will not be liable to shareholders or their representatives for compliance with those laws in good faith.

Taxes. The federal tax treatment of the Fund and distributions to shareholders is briefly highlighted in the Prospectus. The following is only a summary of certain additional tax considerations generally affecting the Fund and its shareholders. The tax discussion in the Prospectus and this SAI is based on tax laws in effect on the date of the Prospectus and SAI. Those laws and regulations may be changed by legislative, judicial, or administrative action, sometimes with retroactive effect. State and local tax treatment may differ from the treatment under the Internal Revenue Code as described below.

Before purchasing Fund shares, investors are urged to consult their tax advisers with reference to their own particular tax circumstances as well as the consequences of federal, state, local and any other jurisdiction's tax rules affecting an investment in the Fund.

Qualification and Taxation as a Regulated Investment Company. The Fund has elected to be taxed as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code. As long as the Fund qualifies as a RIC, the Fund is not subject to federal income tax on the portion of its net investment income (that is, taxable interest, dividends, and other taxable ordinary income, net of expenses) and capital gain net income (that is, the excess of capital gains over capital losses) that it distributed to shareholders.

If the Fund qualifies as a "regulated investment company" under the Internal Revenue Code, it will not be liable for federal income tax on amounts it pays as dividends and other distributions. That qualification enables the Fund to "pass through" its income and realized capital gains to shareholders without having to pay tax on them. The Fund qualified as a regulated investment company in its last fiscal year and intends to qualify in future years, but reserves the right not to qualify. The Internal Revenue Code contains a number of complex tests to determine whether the Fund qualifies. One or more Funds might not meet those tests in a particular year. If the Fund does not qualify, the Fund will be treated for tax purposes as an ordinary corporation and will receive no tax deduction for payments of dividends and other distributions made to shareholders. In such an instance, all of the Fund's dividends would be taxable to shareholders.

Qualifying as a RIC. To qualify as a RIC, the Fund must be a domestic corporation that is either registered under the Investment Company Act as a management company or unit investment trust or is otherwise described in the Internal Revenue Code as having a specific status under the Investment Company Act. The Fund must also satisfy certain tests with respect to (i) the composition of its gross income, (ii) the composition of its assets and (iii) the amount of its dividend distributions.

Gross Income Test. To qualify as a RIC, the Fund must derive at least 90% of its gross income from dividends, interest, certain payments with respect to loans of securities, gains from the sale or other disposition of securities or foreign currencies, and certain other income derived with respect to its business of investing in such securities or currencies (including, but not limited to, gains from options, futures or forward contracts), and net income derived from interests in certain "qualified publicly traded partnerships."

Asset Test. In addition, at the close of each quarter of its taxable year, the Fund must satisfy two asset tests. First, at least 50% of the value of the Fund's assets must consist of securities of other issuers ("Other Issuers"), U.S. Government securities, securities of other RIC's and cash or cash items (including receivables). The securities of an Other Issuer are not counted towards satisfying the 50% test if the Fund either invests more than 5% of the value of the Fund's assets in the securities of that Other Issuer or holds more than 10% of the outstanding voting securities of that Other Issuer. Second, no more than 25% of the value of the Fund's total assets may be invested in (1) the securities of any one issuer (other than U.S. Government securities and the securities of other RIC's), (2) the securities of two or more issuers (other than the securities of other RIC's) that the Fund controls and that are engaged in the same or similar trades or businesses, or (3) the securities of one or more qualified publicly traded partnerships. For purposes of these tests, obligations issued or guaranteed by certain agencies or instrumentalities of the U.S. Government are treated as U.S. Government securities.

Dividend Distributions Test. During the taxable year or, under specified circumstances, within 12 months after the close of the taxable year, the Fund must distribute at least 90% of its investment company taxable income and at least 90% of its net tax-exempt income for the taxable year, which is generally its net investment income and the excess of its net short-term capital gain minus its net long-term capital loss.

Excise Tax on Regulated Investment Companies. Under the Internal Revenue Code, the Fund must pay an annual, non-deductible excise tax unless, by December 31st each year, it distributes (1) 98% of its taxable investment income earned from January 1 through December 31, (2) 98% of its capital gain net income realized in the period from November 1 of the prior year through October 31 of the current year and (3) undistributed amounts from prior years. It is presently anticipated that the Fund will meet these distribution requirements, although to do so the Fund might be required to liquidate portfolio investments in certain circumstances. In some years, the Board and the Manager may determine that it would be in the shareholders' best interests for the Fund to pay the excise tax on undistributed amounts rather than making the required level of distributions. In that event, the tax may reduce the amount available for shareholder distributions.

Taxation of Fund Distributions. Distributions by the Fund will be treated in the manner described below regardless of whether the distributions are paid in cash or reinvested in additional shares of the Fund (or of another fund). The Fund's distributions will be treated as dividends to the extent paid from the Fund's earnings and profits (as determined under the Internal Revenue Code). Distributions in excess of the Fund's earnings and profits will first reduce the adjusted tax basis of a shareholder's shares and, after such tax basis is reduced to zero, will constitute capital gain to the shareholder (assuming the shares are held as a capital asset). The Fund's dividends will not be eligible for the dividends-received deduction for corporations. Shareholders reinvesting a distribution in shares of the distributing Fund, one of the other funds Fund or another fund will be treated as receiving a distribution in an amount equal to the fair market value of the shares received, determined as of the reinvestment date.

Exempt-Interest Dividends. The Fund intends to satisfy the requirements under the Internal Revenue Code during each fiscal year to pay "exempt-interest dividends" to its shareholders. To qualify, at the end of each quarter of its taxable year, at least 50% of the value of the Fund's total assets must consist of obligations described in Section 103(a) of the Internal Revenue Code, as amended. Dividends that are derived from net interest income earned by the Fund on tax-exempt municipal securities and designated as "exempt-interest dividends" in a written notice sent by the Fund to its shareholders within 60 days after the close of the Fund's taxable year will be excludable from gross income of shareholders for federal income tax purposes. To the extent any Fund fails to qualify to pay exempt-interest dividends in any given taxable year, such dividends would be included in the gross income of shareholders for federal income tax purposes.

The Fund will allocate interest from tax-exempt municipal securities (as well as ordinary income, capital gains, and tax preference items discussed below) among its shares according to a method that is based on the gross income allocable to each class of shareholders during the taxable year (or under another method, if prescribed by the IRS and SEC). The percentage of each distribution with respect to a taxable year of the Fund that is an exempt-interest dividend will be the same, even though that percentage may differ substantially from the percentage of the Fund's income that was tax-exempt during a particular portion of the year. This percentage normally will be designated after the close of the taxable year.

Exempt-interest dividends are excludable from a shareholder's gross income for federal income tax purposes. Interest on indebtedness incurred or continued to purchase or carry shares of a regulated investment company paying exempt-interest dividends, such as the Fund, will not be deductible by the investor for federal income tax purposes to the extent attributable to exempt-interest dividends. Shareholders receiving Social Security or railroad retirement benefits should be aware that exempt-interest dividends are a factor in determining whether, and to what extent, such benefits are subject to federal income tax.

A portion of the exempt-interest dividends paid by the Fund may give rise to liability under the federal alternative minimum tax for individual or corporate shareholders. Income on certain private activity bonds issued after August 7, 1986, while excludable from gross income for purposes of the federal income tax, is an item of "tax preference" that must be included in income for purposes of the federal alternative minimum tax for individuals and corporations. "Private activity bonds" are bonds that are used for purposes not generally performed by governmental entities and that benefit non-governmental entities. The amount of any exempt-interest dividends that is attributable to tax preference items for purposes of the alternative minimum tax will be identified when tax information is distributed by the Fund.

In addition, corporate taxpayers are subject to the federal alternative minimum tax based in part on certain differences between taxable income as adjusted for other tax preferences and the corporation's "adjusted current earnings," which more closely reflect a corporation's economic income. Because an exempt-interest dividend paid by the Fund will be included in adjusted current earnings, a corporate shareholder may be required to pay alternative minimum tax on exempt-interest dividends paid by the Fund.

Shareholders are advised to consult their tax advisers with respect to their liability for federal alternative minimum tax, and for advice concerning the loss of exclusion from gross income for exempt-interest dividends paid to a shareholder who would be treated as a "substantial user" or "related person" under Section 147(a) of the Internal Revenue Code with respect to property financed with the proceeds of an issue of private activity bonds held by the Fund.

Ordinary Income Dividends. Distributions from income earned by the Fund from one or more of the following sources will be treated as ordinary income to the shareholder:

• certain taxable temporary investments (such as certificates of deposit, repurchase agreements, commercial paper and obligations of the U.S. Government, or its agencies and instrumentalities);

• income from loans of portfolio securities;

• income or gains from options or futures;

• any net short-term capital gain; and

• any market discount accrual on tax-exempt bonds.

Capital Gain Distributions. The Fund may either retain or distribute to shareholders its net capital gain (the excess of net long-term capital gain over net short-term capital loss). Currently, the Fund intends to distribute these gains. Distributed net capital gain that is properly designated will be taxable to the Fund's shareholders as long-term capital gains, and in the case of non-corporate shareholders, will qualify for the maximum tax rate of 15% for taxable years beginning before 2011. The amount of distributions designated as net capital gain will be reported to shareholders shortly after the end of each year. Such treatment will apply no matter how long the shareholder has held Fund shares and even if the gain was recognized by the Fund before the shareholder acquired Fund shares.

If the Fund elects to retain its net capital gain for a taxable year, the Fund will be subject to tax on such gain at the highest corporate tax rate. Each shareholder of record on the last day of such taxable year will be informed of his or her portion of both the gain and the tax paid, will be required to report the gain as long-term capital gain, will be able to claim the tax paid as a refundable credit, and will increase the basis of his or her shares by the amount of the capital gain reported minus the tax credit.

Backup withholding. The Fund will be required in certain cases to withhold 28% of ordinary income dividends, capital gain distributions and the proceeds of the redemption of shares, paid to any shareholder (1) who has failed to provide a correct taxpayer identification number or to properly certify that number when required, (2) who is subject to backup withholding for failure to report properly the receipt of interest or dividend income, or (3) who has failed to certify to the Fund that the shareholder is not subject to backup withholding or is an "exempt recipient" (such as a corporation). Any tax withheld by the Fund is remitted by the Fund to the U.S. Treasury and is identified in reports mailed to shareholders in January of each year with a copy sent to the IRS. Backup withholding is not an additional tax. Any amount withheld generally may be allowed as a refund or a credit against a shareholder's federal income tax liability, provided the required information is timely provided to the IRS.

Tax Consequences of Share Redemptions. If all or a portion of a shareholder's investment in the Fund is redeemed, the shareholder will recognize a gain or loss on the redeemed shares equal to the difference between the proceeds of the redeemed shares and the shareholder's adjusted tax basis in the shares. In general, any gain or loss from the redemption of shares of the Fund will be considered capital gain or loss if the shares were held as a capital asset and will be long-term capital gain or loss if the shares were held for more than one year. Any capital loss arising from the redemption of shares held for six months or less, however, will be treated as a long-term capital loss to the extent of the amount of capital gain dividends received on those shares. Special holding period rules under the Internal Revenue Code apply in this case to determine the holding period of shares. There are limits on the deductibility of capital losses in any year.

All or a portion of any loss on redeemed shares may be disallowed if the shareholder purchases other shares of the Fund within 30 days before or after the redemption (including purchases through the reinvestment of dividends). In that case, the basis of the acquired shares will be adjusted to reflect the disallowed loss.  Losses realized by a shareholder on the redemption of Fund shares within six months of purchase will be disallowed for federal income tax purposes to the extent of exempt-interest dividends received on such shares.  If a shareholder exercises the exchange privilege within 90 days after acquiring Fund shares, any loss that the shareholder recognizes on the exchange will be reduced, or any gain will be increased, to the extent that sales charge paid on the exchanged shares reduces any charges the shareholder would have incurred on the purchase of the new shares in the absence of the exchange privilege. Such sales charge will be treated as an amount paid for the new shares.

Taxation of Foreign Shareholders. Under the Internal Revenue Code, taxation of a foreign shareholder depends primarily on whether the foreign shareholder's income from the Fund is effectively connected with the conduct of a U.S. trade or business. Typically, ordinary income dividends paid from a mutual fund are not considered "effectively connected" income. "Foreign shareholders" include, but are not limited to, a nonresident alien individual, a foreign trust, a foreign estate, a foreign corporation, or a foreign partnership.

If a foreign shareholder fails to provide a properly completed and signed Certificate of Foreign Status, the Fund will be required to withhold U.S. tax on ordinary income dividends, capital gains distributions and the proceeds of the redemption of shares. Provided the Fund obtains a proper certification of foreign status, ordinary income dividends that are paid by the Fund to foreign shareholders and that are not "effectively connected income," will be subject to a U.S. withholding tax. The tax rate may be reduced if the foreign person's country of residence has an income tax treaty with the United States allowing for a reduced tax rate on ordinary income dividends paid by the Fund. If the ordinary income dividends from the Fund are effectively connected with the conduct of a U.S. trade or business, then the foreign shareholder may claim an exemption from the U.S. withholding tax described above provided the Fund obtains a properly completed and signed Certificate of Foreign Status. Any tax withheld by the Fund is remitted to the U.S. Treasury and all income and any tax withheld is identified in reports mailed to shareholders in the early part of each year with a copy sent to the IRS. Capital gain dividends are not subject to U.S. withholding tax unless the recipient is a nonresident alien who is present in the United States for 183 days or more during the taxable year in which the dividends are received. A foreign individual who is present in the United States for 183 days or more generally loses his or her status as a nonresident alien.

For taxable years of the Fund beginning before January 1, 2010, properly designated dividends are generally exempt from U.S. federal withholding tax on foreign persons provided such dividends (i) are derived from the Fund's "qualified net interest income" (generally, the Fund's U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is a 10% or greater shareholder, reduced by expenses that are allocable to such income) or (ii) are derived from the Fund's "qualified short-term capital gains" (generally, the excess of the Fund's net short-term capital gain over the Fund's net long-term capital loss for such taxable year). In order to qualify for this exemption from withholding, a shareholder that is a foreign person must comply with applicable certification requirements relating to its non-U.S. status. However, depending on its circumstances, the Fund may designate some, all, or none of its potentially eligible dividends as interest-related dividends or as short-term capital gain dividends, and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding on foreign persons. In the case of shares held through an intermediary, the intermediary may withhold even if the Fund designates the payment as qualified net interest income or qualified short-term capital gain. Legislation to extend this exemption to tax years beginning on or after January 1, 2010 has not been enacted. Shareholders that are foreign persons should contact their intermediaries with respect to the application of these rules to their accounts.

The tax consequences to foreign persons entitled to claim the benefits of an applicable income tax treaty may be different from those described in this SAI. Foreign shareholders are urged to consult their tax advisers with respect to the particular tax consequences of an investment in the Fund, including the applicability of the U.S. withholding taxes described above.

Appendix A

OppenheimerFunds Special Sales Charge Arrangements and Waivers

In certain cases, the initial sales charge that applies to purchases of Class A shares of the Oppenheimer funds or the contingent deferred sales charge ("CDSC") that may apply to Class A, Class B, Class C or N shares may be waived.¹ That is because of the economies of sales efforts realized by OppenheimerFunds Distributor, Inc., (referred to in this document as the "Distributor"), or by dealers or other financial institutions that offer those shares to certain classes of investors. Not all waivers apply to all funds.

For the purposes of some of the waivers described below and in the Prospectus and Statement of Additional Information of the applicable Oppenheimer funds, the term "Retirement Plan" refers to the following types of plans:

1. plans created or qualified under Sections 401(a) or 401(k) of the Internal Revenue Code,
2. non-qualified deferred compensation plans,
3. employee benefit plans,²
4. Group Retirement Plans,³
5. 403(b)(7) custodial plan accounts, and 
6. Individual Retirement Accounts ("IRAs"), including traditional IRAs, Roth IRAs, SEP-IRAs, SARSEPs or SIMPLE plans

The interpretation of these provisions as to the applicability of a special arrangement or waiver in a particular case is in the sole discretion of the Distributor or the transfer agent (referred to in this document as the "Transfer Agent") of the particular Oppenheimer fund. These waivers and special arrangements may be amended or terminated at any time by a particular fund, the Distributor, and/or OppenheimerFunds, Inc. (referred to in this document as the "Manager").

Waivers that apply at the time shares are redeemed must be requested by the shareholder and/or dealer in the redemption request.

I. Applicability of Class A Contingent Deferred Sales Charges in Certain Cases

Purchases of Class A Shares of Oppenheimer Funds That Are Not Subject to Initial Sales Charge but May Be Subject to the Class A Contingent Deferred Sales Charge (unless a waiver applies).

There is no initial sales charge on purchases of Class A shares of any of the Oppenheimer funds in the cases listed below. However, these purchases may be subject to the Class A CDSC if redeemed within 18 months (24 months in the case of shares of Oppenheimer Rochester National Municipals and Rochester Fund Municipals shares purchased prior to 10/22/07) of the beginning of the calendar month of their purchase, as described in the Prospectus (unless a waiver described elsewhere in this Appendix applies to the redemption). Additionally, on shares purchased under these waivers that are subject to the Class A CDSC, the Distributor will pay the applicable concession described in the Prospectus under "Class A Contingent Deferred Sales Charge."⁴ This waiver provision applies to:

• Purchases of Class A shares aggregating $1 million or more.

• Purchases of Class A shares by a Retirement Plan that was permitted to purchase such shares at net asset value but subject to a contingent deferred sales charge prior to March 1, 2001. That included plans (other than IRA or 403(b)(7) Custodial Plans) that: 1) bought shares costing $500,000 or more, 2) had at the time of purchase 100 or more eligible employees or total plan assets of $500,000 or more, or 3) certified to the Distributor that it projects to have annual plan purchases of $200,000 or more.

• Purchases by an OppenheimerFunds-sponsored Rollover IRA, if the purchases are made:

1. through a broker, dealer, bank or registered investment adviser that has made special arrangements with the Distributor for those purchases, or
2. by a direct rollover of a distribution from a qualified Retirement Plan if the administrator of that Plan has made special arrangements with the Distributor for those purchases.

• Purchases of Class A shares by Retirement Plans that have any of the following record-keeping arrangements:

1. The record keeping is performed by Merrill Lynch Pierce Fenner & Smith, Inc. ("Merrill Lynch") on a daily valuation basis for the Retirement Plan. On the date the plan sponsor signs the record-keeping service agreement with Merrill Lynch, the Plan must have $3 million or more of its assets invested in (a) mutual funds, other than those advised or managed by Merrill Lynch Investment Management, L.P. ("MLIM"), that are made available under a Service Agreement between Merrill Lynch and the mutual fund's principal underwriter or distributor, and (b) funds advised or managed by MLIM (the funds described in (a) and (b) are referred to as "Applicable Investments"). The record keeping for the Retirement Plan is performed on a daily valuation basis by a record keeper whose services are provided under a contract or arrangement between the Retirement Plan and Merrill Lynch. On the date the plan sponsor signs the record keeping service agreement with Merrill Lynch, the Plan must have $5 million or more of its assets (excluding assets invested in money market funds) invested in Applicable Investments.
2. The record keeping for the Retirement Plan is performed on a daily valuation basis by a record keeper whose services are provided under a contract or arrangement between the Retirement Plan and Merrill Lynch. On the date the plan sponsor signs the record keeping service agreement with Merrill Lynch, the Plan must have $5 million or more of its assets (excluding assets invested in money market funds) invested in Applicable Investments.
3. The record keeping for a Retirement Plan is handled under a service agreement with Merrill Lynch and on the date of the plan sponsor signs that agreement, the Plan has 500 or more eligible employees (as determined by the Merrill Lynch plan conversion manager).

These may include, for example, medical savings accounts, payroll deduction plans or similar plans. The fund accounts must be registered in the name of the fiduciary or administrator purchasing the shares for the benefit of participants in the plan.

3. The term "Group Retirement Plan" means any qualified or non-qualified retirement plan for employees of a corporation or sole proprietorship, members and employees of a partnership or association or other organized group of persons (the members of which may include other groups), if the group has made special arrangements with the Distributor and all members of the group participating in (or who are eligible to participate in) the plan purchase shares of an Oppenheimer fund or funds through a single investment dealer, broker or other financial institution designated by the group. Such plans include 457 plans, SEP-IRAs, SARSEPs, SIMPLE plans and 403(b) plans other than plans for public school employees. The term "Group Retirement Plan" also includes qualified retirement plans and non-qualified deferred compensation plans and IRAs that purchase shares of an Oppenheimer fund or funds through a single investment dealer, broker or other financial institution that has made special arrangements with the Distributor.

4. However, that concession will not be paid on purchases of shares in amounts of $1 million or more (including any right of accumulation) by a Retirement Plan that pays for the purchase with the redemption proceeds of Class C shares of one or more Oppenheimer funds held by the Plan for more than one year.

5. This provision does not apply to IRAs.

6. This provision only applies to qualified retirement plans and 403(b)(7) custodial plans after your separation from service in or after the year you reached age 55.

7. The distribution must be requested prior to Plan termination or the elimination of the Oppenheimer funds as an investment option under the Plan.

8. This provision does not apply to loans from 403(b)(7) custodial plans and loans from the OppenheimerFunds-sponsored Single K retirement plan.

9. This provision does not apply to 403(b)(7) custodial plans if the participant is less than age 55, nor to IRAs.

Appendix B

Special Investment Considerations of State Municipal Securities. As explained each Fund's Prospectus, each Fund's investments are highly sensitive to the fiscal stability of it's respective state and its subdivisions, agencies, instrumentalities or authorities, which issue the municipal securities in which the Fund invests. The following information on risk factors in concentrating in a state's municipal securities supplements the information contained in the Prospectus, and is only a summary that highlights some of the more significant financial trends, based on publicly available reports prepared by state government and budget officials, official statements and prospectuses relating to securities offerings of or on behalf of the state, its agencies, instrumentalities and political subdivisions, and other publicly available documents, as available on the date of this Statement of Additional Information. More information about state specific risks may be available from official state resources.

The Funds have not independently verified this information. No representation is made as to the accuracy of this information. State bond ratings provided below are current as of the date specified. Unless stated otherwise, the ratings indicated are for obligations of the state. A state's political subdivisions may have different ratings which are unrelated to the ratings assigned to state obligations. Investors should note that the creditworthiness of obligations issued by a state's local municipal issuers may be unrelated to the creditworthiness of obligations issued by the state itself, and that there may be no obligation on the part of the state to make payment on such local obligations in the event of the default.

To the extent that any statements made below involve matters of forecasts, projections, opinions, assumptions or estimates, whether or not expressly stated to be such, they are made as such and not as representations of fact or certainty, and no representation is made that any of these statements have been or will be realized. All forecasts, projections, assumptions, opinions or estimates are "forward looking statements," which must be read with an abundance of caution and which may not be realized or may not occur in the future.

Arizona

State Economy. Since the end of World War II, Arizona has consistently ranked among America's fastest growing states. While that growth has fueled State revenues, it has also increased demand for a variety of State services, which include education, health care and corrections. Arizona's economy has been negatively impacted by the recession that began in December 2007. Since that time, the State's unemployment rate has more than doubled, from 4.3% in December 2007 to 9.2% in December 2009. Additionally, according to the Governor's budget for fiscal year 2011 (the "Governor's Budget"), released January 8, 2010, the State's retail activity is down by 19.7%, home prices have fallen 41.8% and construction activity, historically one of the pillars of the State's economy, is down by 51.8%, when compared with December 2007.

State revenues have declined for three consecutive years. For fiscal year 2010, they are projected to be 34% less than in fiscal year 2007. At the same time as revenues have decreased, the State has faced increased demand for State services. The increase in demand for State services during the recession is illustrated by enrollment growth in the Arizona Health Care Cost Containment System ("AHCCCS"), the State's Medicaid agency. Since the end of fiscal year 2007, AHCCCS has added 312,400 new members. The State began facing budget gaps in fiscal year 2008. During fiscal year 2008, Arizona balanced its budget in part by relying on the "rainy day" fund. By fiscal year 2009, the budget challenges had grown, and again the "rainy day" fund and other sources of one-time revenues were used. In addition, certain agencies had their obligations deferred; agency budgets were reduced; and federal American Recovery & Reinvestment Act (the "ARRA") monies were used. Nevertheless, fiscal year 2009 ended with a $480 million deficit. According to the Governor's Budget, the State faces a fiscal year 2010 budget shortfall that, without any action is projected to reach $1.4 billion by June 30, 2010. The projected shortfall equals 36% of the remaining operating budget for fiscal year 2010 and 46% of the expected remaining revenues to be received in fiscal year 2010.

In addition, the State faces a projected fiscal year 2011 deficit of $3.2 billion. While the recession is a significant factor in the fiscal year 2010 deficit and in the deficits projected for 2011 and beyond, the State also has a structural deficit, in that there is a misalignment between its revenues and its expenditures. Factors contributing to this misalignment include a combination of reduced revenues, program expansions, continuing population growth, constraints imposed by voters, and the federal government.

Revenues. State revenues have been reduced partially by a series of tax cuts in personal and corporate income taxes. The most recent significant reduction for the corporate income tax occurred in calendar year 2005. This change (relating to the allocation of multi-state corporate income to Arizona) was estimated at the time of enactment to have, in fiscal year 2011, a fully phased-in impact of $120 million. The most recent significant reduction to the individual income tax was enacted in calendar year 2006. This legislation provided for a 5% rate reduction in fiscal year 2006 and an additional 5% rate reduction in fiscal year 2007. The cumulative impact of these reductions was estimated at the time of enactment to be $334 million per year.

Programs and Initiatives. Before the current recession started in December 2007, the State, via legislation, judicial mandate or public vote, embarked on several costly programs and initiatives without identifying ways to pay for them. An example involves a property tax reform that has gradually reduced the local property tax, and shifted the school funding obligation to the State General Fund ("General Fund"). This local property tax reduction is estimated to have cost the State approximately $700 million in fiscal year 2010. Another example involves a voter initiative that expanded AHCCCS eligibility, resulting in additional enrollment in AHCCCS. The estimated fiscal year 2010 cost for the expansion in AHCCCS eligibility has grown to nearly $800 million in State funds (excluding the impact of enhanced ARRA funding).

Limitations on Government Management of Revenues. Two voter-approved initiatives have limited the ability of State government to manage revenues and expenditures and exercise budgetary control: In 1992, in order to make it more difficult for the State Legislature ("Legislature") to raise taxes or fees, Arizona voters approved Proposition 108. The measure requires a two-thirds vote of each house of the Legislature for any act that results in a "net increase" in State revenues. In 1998, the voters approved Proposition 105, which limits the Legislature's ability to change the provisions of voter approved programs and forces the State to continue spending for those same programs without any consideration of budget problems.

Federal Government. The ARRA provides economic stimulus funding and federal assistance to state governments to balance budgets. From fiscal year 2009 through fiscal year 2011, the State's General Fund is scheduled to receive approximately $2.8 billion in ARRA funding, to be used largely for education and for health care for low-income persons. While the ARRA funding has helped the State address its recent and expected deficits, it comes with certain conditions. Most notably, the State agreed to maintain, through the end of fiscal year 2011, spending for K-12, community college and universities at the fiscal year 2006 levels. The State also agreed to maintain, through December 2010, AHCCCS eligibility criteria as of the date of ARRA's enactment, notwithstanding that, since the enactment date, Arizona's AHCCCS enrollment has grown by 188,500 Arizonans. As a result of these ARRA "maintenance of effort" requirements, approximately $6.8 billion, representing two-thirds of the State's $9.9 billion "continuing service" budget for fiscal year 2011, is federally protected from spending reductions.

Governor's Budget. The Governor's Budget, introduced on January 8, 2010, contains recommendations to close the projected $1.4 fiscal year 2010 budget gap as well as recommendations for resolving the projected $3.2 billion fiscal year 2011 budget gap. The discussion that follows highlights the major features of the Governor's Budget for the remainder of fiscal year 2010 and for fiscal year 2011.

The Governor's Budget increases spending in certain areas. These include funding for AHCCCS to accommodate federally and voter mandated funding for growing Medicaid populations; the Arizona Department of Corrections for opening new state prisons; employee health care; and growing debt service. Additionally, almost $1 billion in federal stimulus funding provided in fiscal year 2010 expires in fiscal year 2011. The Governor's Budget recommends replacing less than half ($441.5 million) with General Fund dollars.

One focus of the Governor's Budget is a plan to better align revenues and expenditures. Examples of the restructuring include, but are not limited to, K-12 education, healthcare, and the lottery. In regard to K-12 education, the Governor's Budget recommends eliminating State support of full-day kindergarten and eliminating the excess utility supplement. These two measures combined are projected to save approximately $315 million. In regard to health care, the Governor's Budget recommends withdrawing General Fund support for the Proposition 204 population within Medicaid, and, as a consequence, eliminating health coverage for childless adults who were added under Proposition 204. Because this funding is protected by both federal law and the Proposition 105, the recommendation is based on a January 1, 2011 start date, after the federal protections have expired, the Medicaid waiver has been amended, and the recommendation is ratified by the voters. In regard to the lottery, the Governor's Budget requests a 20-year extension of the lottery, with the retroactive redirection of the major revenue streams to the General Fund. The redirection is projected to provide $29.8 million in fiscal year 2010 and $59.6 million in fiscal year 2011.

The Governor's Budget proposes certain temporary measures pertaining to funding education. For example, the Governor's Budget recommends a temporary $180 million decrease in soft capital funding for school districts and a $10 million reduction in charter school per-pupil support levels. After accounting for that reduction, and the elimination of State funding for full-day kindergarten discussed above, expenditures for the K-12, community college, and university systems will be protected
at fiscal year 2006 levels. The Governor's Budget also recommends an across-the-board salary reduction for all non-university State employees.

The Governor's Budget proposes the use of one-time funds for both fiscal year 2010 and fiscal year 2011. For fiscal year 2010, the Governor's Budget recommends expanding the Sale/Leaseback program by $300 million and issuing $450 million in revenue bonds supported by lottery revenues. For fiscal year 2011, the Governor's Budget proposes a short-term borrowing of $260 million from the Arizona Early Childhood Development & Health Board, also known as First Things First. The
Governor's Budget also recommends an additional $450 million in education rollovers, including the May K-12 payment and $100 million in university payments.

The Governor's Budget recommends a temporary (March 1, 2010, through fiscal year 2013) "one cent" increase to the Transaction Privilege Tax ("TPT"). During the same period, the Governor's Budget also proposes both expanding the TPT base to include repair services and eliminating the TPT accounting credit. These changes will raise $215 million in fiscal year 2010 and $1.07 billion in fiscal year 2011. The Governor's Budget further proposes lowering the threshold for estimated TPT payments from the current level of $1 million in TPT liability from the preceding year to $100,000. This change, while merely an acceleration of existing liability, is projected to provide a onetime benefit of $48 million in fiscal year 2010. Finally, the Governor's Budget proposes permanent changes to the Arizona Department of Revenue ("DOR"), including increasing the DOR audit and collections staffs and making several statutory changes to increase collection of tax liabilities. The Governor's Budget estimates these changes will improve collections by $17.8 million in fiscal year 2011.

Constitutional Limitations on Taxes. The Arizona Constitution limits the amount of debt that can be issued by the State's counties, cities, towns, school districts and other municipal corporations in the form of indebtedness payable from property taxes or other general fund sources. In general, those political subdivisions may not become indebted in an amount exceeding 6% of the value of the taxable property in the political subdivision without the approval of a majority of the qualified electors voting at an election. Furthermore, no county or school district may become indebted in an amount exceeding 15% (30% for unified school districts) of the value of the taxable property, even with voter approval. In addition, with voter approval, incorporated cities or towns may become indebted in an amount up to 20% of the value of the taxable property for the purposes of supplying water, light, sewers, open space preserves, parks, playgrounds, recreational facilities, transportation and public safety. These constitutional debt limits generally do not apply to revenue bonds payable from special fund revenue sources.

State Debt. The State, itself, has no general obligation debt. The Arizona Department of Transportation, the Arizona Board of Regents, the Arizona Power Authority, the Water Infrastructure and Finance Authority of Arizona and the Arizona School Facilities Board are authorized to issue revenue bonds for their respective purposes. In addition, the State has financed certain capital improvements and equipment through the execution and sale of certificates of participation, which represent undivided agreements that are subject to annual appropriations by the Arizona Legislature.

Litigation. The State is party to numerous legal proceedings, many of which normally occur in government operations. In addition, the State is involved in certain other legal proceedings that, if decided against the State, might require the State to make significant future expenditures or substantially impair future revenue sources. Because of the prospective nature of these proceedings, it is not presently possible to predict the outcome of such litigation, estimate the potential impact on the ability of the State to pay debt service costs on its obligations, or determine what impact, if any, such proceedings may have on a fund's investments.

Bond Ratings. As of March 23, 2010, the State had an issuer rating of AA- by Standard & Poor's and A1 by Moody's Investors Service, Inc., each reflecting a recent downgrade. On December 23, 2009, S&P lowered the State's issuer rating from to AA- from AA and on December 22, 2009, Moody's lowered the State's issuer rating to A1 from Aa3.

Maryland

Economic Climate. Maryland has a population of approximately 5.6 million, with employment based largely in services, trade, and government. Those sectors, along with financial activities, are the largest contributors to the gross state product, according to the U.S. Department of Commerce, Bureau of Economic Analysis. Population is concentrated around the Baltimore and Washington, D.C. PMSAs, and proximity to Washington, D.C. influences the above average percentage of employees in government. Manufacturing, on the other hand, is a much smaller proportion of employment than for the nation as a whole. Annual unemployment rates have been below those of the national average for each of the last 20 years. The unemployment figure for 2008 was 4.4% compared to a national rate for the same period of 5.8%. In September 2009 the rates had increased to 7.2% in Maryland and 9.8% in the United States. Total employment increased by 6.7% between 1999 and 2008. The State's per capita personal income was the sixth highest in the country in 2008, according to the Bureau of Economic Analysis, at 121% of the national average.

Maryland residents received approximately $271.0 billion in personal income in 2008. Maryland's Total Personal Income increased at a rate of 3.8%, slightly below the national average of 3.9%. Per capita income, however, remained significantly above the national average in 2008, $48,091 in Maryland compared with the national average of $39,751. In 2008, Maryland's per capita personal income ranked sixth highest in the nation.

Maryland is more reliant on the service and government sectors than the nation as a whole, while the manufacturing sector is much less significant than it is nationwide. As one of the wealthier states, a greater share of personal income is derived from dividends, interest and rent, and a lesser share comes from transfer payments.

The Maryland Economy. While most of the current difficulties caused by the recession are affecting the State's economy, these problems have not hit Maryland as hard as many other states. One positive future development for the State is the implementation of the 2005 decisions of the Base Realignment and Closure Commission ("BRAC"). This
process has begun to bring to Maryland jobs, families with income, and increased demand for goods and services starting in 2009.

Real Estate. Home sales in Maryland started to slow in 2005 and prices began to decline in 2008. The Maryland Realtors Association reports the median price for a home sold in 2008 declined 7.5% from the median price in 2007. The construction industry has contracted as new home construction slowed significantly and commercial construction was unable to compensate. In addition, retail sales of items such as appliances and furniture, typically associated with a strong housing market, have declined.

Biotechnology. Maryland is well positioned in the front ranks of the biotechnology field. The State's concentration of higher education and research institutions, particularly medical schools, a thriving pharmaceuticals industry and one of the most highly educated workforces in the country has created growth opportunities for the biotech companies that have located or started up here.

Base Realignment and Closure. The State is poised to receive more federal jobs than any other state in the country from the 2005 BRAC process and is now preparing for an influx of an estimated 45,300 jobs statewide starting in 2009. The majority of these jobs are expected to be located within an eight county area in central Maryland (Anne Arundel, Howard, Montgomery, Prince George's, Harford, Baltimore and Cecil counties, and Baltimore City).

Budget Process and Other Fiscal Matters. The State enacts its budget annually. Revenues are derived largely from certain broad-based taxes, including statewide income, sales, motor vehicle, and property taxes. Non-tax revenues are largely from the federal government for transportation, health care, welfare and other social programs. General fund revenues on a budgetary basis realized in the State's fiscal year ended June 30, 2009, were below estimates by $356.4 million, or 2.7%. The State ended fiscal year 2009 with a $87.2 million general fund balance on a budgetary basis. This balance reflects a $349.9 million decrease compared to the balance projected at the time the 2010 budget was enacted. In addition, there was a balance in the Revenue Stabilization Account of $691.8 million. For fiscal year 2010, the total budget is $31.5 billion, a $646.0 million increase over fiscal year 2009. The General Fund accounts for approximately $13.3 billion, of which the largest expenditures are for health and education, which together represent 74.3% of total general fund expenditures. General fund expenditures exclude transportation, which is funded with special fund revenues from the Transportation Trust Fund.

On a GAAP basis, the fiscal year 2008 reserved general fund balance was $1,388.2 million, while the unreserved, designated and undesignated, fund balances were $538.0 million and $959.4 million, respectively; this compares to the reserved general fund balance of $2,373.7 million, and unreserved, designated and undesignated fund balances of $195.1 million and $690.2 million respectively at the end of fiscal year 2007. The total GAAP fund balance for fiscal year 2008 was $2,885.6 million compared with a total GAAP fund balance of $3,259.0 million for fiscal year 2007.

The State Reserve Funds consist of the Revenue Stabilization Account and other reserve funds, which together totaled $701.8 million at the end of fiscal year 2009. The Revenue Stabilization Account was established to retain State revenues for future needs and to reduce the need for future tax increases. Current estimates for the close of fiscal year 2010 project a total reserve balance of $641.8 million, of which $640.8 million is projected to be in the Revenue Stabilization Account. The projected balance in the Revenue Stabilization Account represents 5.2% of estimated general fund revenues. Maryland had $8,676.8 million of net State tax-supported debt outstanding as of June 30, 2009. General obligation bonds accounted for $5,873.6 million of that amount. In fiscal year 2009, debt service on general obligation bonds was paid primarily from State property tax receipts.

Department of Transportation bonds outstanding account for another $1,582.6 million of State tax-supported debt as of June 30, 2009; the debt service on those bonds is payable from taxes and fees related to motor vehicles and motor vehicle fuel and a portion of the corporate income tax. Debt obligations issued by the Maryland Stadium Authority in the form of lease-backed revenue bonds account for $256.0 million of State tax-supported debt outstanding as of June 30, 2009. Rental payments under the leases are subject to annual appropriation by the General Assembly. The State also has financed construction and acquisition of various other facilities and equipment through lease-type financing, subject to annual appropriation by the General Assembly, in the amount of $213.4 million as of June 30, 2009. There was $704.4 million of Grant Anticipation Revenue Vehicle ("GARVEE") Bonds outstanding as of June 30, 2009. Debt Service is paid from a portion of Maryland's federal highway aid. The Maryland Department of Environment had Bay Restoration Revenue Bonds outstanding in the amount of $46.8 million as of June 30, 2009.

The State had $2,328.4 million of authorized but unissued debt as of June 30, 2009.

Litigation. The State and its units are parties to numerous legal proceedings, many of which normally occur in governmental operations. The legal proceedings are not, in the opinion of the Attorney General, likely to have a material adverse effect on the State's financial position.

Ratings of Maryland Municipal Securities. As of July 14, 2010, Moody's, Standard & Poor's, and Fitch have rated the State's general obligation bonds "Aaa", "AAA" and "AAA", respectively. These ratings reflect the credit quality of the State only, and do not indicate the creditworthiness of securities of other issuers located in the State. An explanation of the significance of a particular rating may be obtained from the rating agency furnishing it. These ratings may be changed at any time and no assurance can be given that they will not be revised downward or withdrawn by any or all rating agencies, if in the judgment of any or all, circumstances should warrant such actions. Any downward revision or withdrawal of any of the ratings could have an adverse effect on market prices for the related Maryland Municipal Securities.

Massachusetts

Massachusetts is a relatively slow growing but densely populated state. Its economy is driven by the education, healthcare, financial services, and high tech industries. While the Commonwealth has per capita income that is among the highest in the country, its per capita debt is among the highest in the country as well. The concentration of colleges and universities in Massachusetts adds employment stability and mitigates job losses during economic downturns. Residents of the Commonwealth are more highly educated than the national average, with 38.1% of adults earning at least a bachelor's degree, compared with 27.7% nationally.

Unemployment in the Commonwealth stood at 9.0% in June 2010, below the national rate of 9.5%. The Commonwealth's Executive Office of Labor and Workforce Development reported that June 2010 was the sixth straight month of private sector job growth. Sectors showing the largest gains included leisure and hospitality, construction, and trade, transportation and utilities. Manufacturing displayed some weakness after five consecutive months of job growth. This recent data, reflecting a slower growth pace for Massachusetts, follows reports that Massachusetts had pulled out of the recession ahead of the nation.

The Commonwealth faces mounting healthcare expenditures as a result of April 2006 legislation which essentially mandated healthcare insurance for all residents of Massachusetts. Costs associated with the legislation have exceeded initial estimates and are expected to continue to rise. Additional pressure is coming from health insurance companies, seeking to raise revenue through premium hikes of 8% to 32% annually. In an effort to keep healthcare costs affordable for the Commonwealth and its residents, in April 2010, the Governor announced a cap on all healthcare insurance premium rate hikes of 7.7% annually. This cap, combined with other measures, is designed to keep healthcare costs within the Commonwealth's budgetary guidelines.

The Commonwealth's revenue streams are also facing pressure. In July 2010, proponents of initiatives to remove the sales tax on alcoholic beverages and reduce the sales and use tax rates in the Commonwealth from 6.25% to generally 3% succeeded in securing spots for these initiatives on the November 2010 ballot. If voters pass the initiatives, the Commonwealth could lose substantial annual revenue starting January 1, 2011, thus forcing the Commonwealth to make significant mid-year adjustments.

Regardless of the outcome of the sales and use tax initiatives, Massachusetts is taking steps to address budget concerns and raise revenue. For example, in April 2010, the Massachusetts House approved legislation establishing two casinos in the Commonwealth and authorizing slot machines at racetracks. In June 2010, the Massachusetts Senate passed a separate, divergent bill to expand gambling, and currently a legislative panel is working to reach an agreement on the two bills. The legislation, if enacted, could generate significant additional licensing fees and annual tax revenue.

As generally discussed below, the Commonwealth's expenditures include substantial payments for local aid to mitigate the impact of local property tax limits or local programs and services, health care, employment benefits, as well as for education, public safety, energy and environmental affairs, debt service and various other program expenditures. Its revenues come from a variety of taxes and other non-tax sources, including the federal government.

Fiscal 2010. The fiscal 2010 general appropriations act, including vetoes, totaled $27.046 billion. The fiscal 2010 budget provided $4.837 billion of state-funded local aid to municipalities, an increase from $4.724 billion in fiscal 2009. It also included state funding for public education aid of approximately $3.870 billion. The Commonwealth is also projected to spend $936 million in unrestricted general government aid in fiscal 2010 to provide funds for municipal use.

Fiscal 2010 estimated spending is $9.291 billion. The Commonwealth's Medicaid program, MassHealth, generally receives at least 50% in federal reimbursement on most expenditures. For fiscal 2010 nearly 30% of the Commonwealth's budget is devoted to Medicaid. It is the largest and one of the fastest growing items in the Commonwealth's budget. The fiscal 2010 budget also included $631.7 million for the Commonwealth Care program created in 2006, a decrease from fiscal 2009 program spending, as well as lesser amounts for certain health safety net services. In addition, the Commonwealth has projected expenditures and other uses for other health and human services at $4,658.8 billion for fiscal 2010.

Budgeted funding at the Group Insurance Commission which provides health insurance benefits to active and retired state employees and their dependents totaled $1.435 billion in fiscal 2010. Almost all non-federal public employees in the Commonwealth participate in defined-benefit pension plans administered pursuant to state law by various public retirement systems. According to the approved funding schedule for pension obligations, the fiscal 2010 payment is $1.377 billion. (The Commonwealth is also required to provide certain health care and life insurance benefits for retired employees of the Commonwealth and certain governmental agencies; however, the Commonwealth is currently not fully funding the amortization of the actuarial liabilities associated with these benefits.)

On July 15, 2010 the Massachusetts Department of Revenue released its preliminary June tax revenue report, indicating that collections for fiscal 2010 totaled $18.538 billion, an increase of $279 million, or 1.5%, compared to fiscal 2009. The fiscal 2010 tax revenue increase from fiscal 2009 is attributable in large part to an increase of approximately $743 million, or 19.2%, in sales tax collections, an increase of approximately $20 million, or 1.0%, in corporate and business tax collections, and a decrease of approximately $474 million, or 4.5%, in personal income tax collections.

The Commonwealth receives federal reimbursements for the federal share of entitlement programs such as Medicaid and through block grants for various programs. Federal reimbursements for fiscal 2010 are projected to be $8.589 billion, an increase from $8.251 billion for fiscal 2009. Other non-tax revenues for fiscal 2010 are projected to be $2.889 billion, an increase from $2.326 billion for fiscal 2009. In addition, for fiscal 2010, the State Lottery Commission projects net operating revenues of approximately $987.0 million which would result in a surplus over the fiscal 2010 amount budgeted for lottery administrative expenses and transfers for local aid to cities and towns.

During fiscal 2010, as estimates of revenues and expenditures were adjusted, the Commonwealth implemented a number of responsive measures, including spending cuts and funds transfers. As of June 2010, the Governor had signed fiscal 2010 supplemental appropriations of more than $665 million. The majority of additional funding was used to support state safety-net programs and services impacted by the economic downturn. There have also been other unanticipated costs, such as special elections and increased funding for snow and ice removal, that have required supplemental funding. On July 9, 2010, the Governor filed a final supplemental appropriations bill for fiscal 2010 that provides for net new spending in the amount of $28.5 million. This funding primarily addresses outstanding liabilities of the Commonwealth. There are sufficient resources available to cover these expenditures.

Fiscal 2011. On June 30, 2010 the Governor approved the fiscal 2011 budget, which totaled $27.570 billion. The Governor vetoed approximately $457 million from the budget that was enacted by the Legislature, including $372 million of appropriations funded from additional federal Medicaid matching funds which was assumed in the budget, but the United States Congress has not yet approved, $54 million in anticipated federal assistance for needy families that has also not yet been approved by Congress, and approximately $17 million in lottery revenues in excess of the State Lottery Commission's revenue projections. The Governor also vetoed certain funding in the fiscal 2011 budget to address these anticipated exposures. With respect to the recently enacted federal Patient Protection and Affordable Health Care Act (P.L. 111-148), the Commonwealth is in a more favorable position than many states; it will not need to devote new state funding to cover populations under the new federal legislation since it is already providing coverage exceeding the new federal coverage levels.

The fiscal 2011 budget includes a $100 million withdrawal from the Commonwealth's stabilization fund (projected to have a fiscal 2010 year-end balance of $656.6 million), the use of fiscal 2011 interest earnings on the stabilization fund and an additional $95 million in savings by suspending the statutory carryover of the general fund balance into the next fiscal year. Taking all that into account, the stabilization fund is projected to have a $556 million balance at the end of fiscal 2011. The fiscal 2011 budget also relies on $809 million in remaining available federal funds under the American Recovery and Reinvestment Act of 2009.

The failure of Congress to approve the six-month Medicaid matching funds extension and the associated loss of federal revenue to the Commonwealth will require significant reductions to programs and services. These spending reductions, along with pressures related to programs and services such as MassHealth and other safety-net programs, will require departments and agencies to manage over $1 billion in spending reductions and potential exposures during fiscal 2011. State departments and agencies are preparing implementation plans detailing the steps to manage their fiscal 2011 programs and services, generally at reduced funding levels from the previous fiscal year. See also the discussion of sales and use tax initiatives above.
The Commonwealth's five-year capital investment plan calls for the issuance of approximately $2.025 billion of bonds in fiscal 2011. This amount includes $1.625 billion in general obligation bonds and $760 million of borrowing for the Commonwealth's accelerated bridge program, including $360.0 million carried over from fiscal 2010.

Ratings of the Commonwealth's Securities. As of July 2010, Standard & Poor's, Fitch and Moody's rated the Commonwealth's general obligation bonds "AA," "AA+," and "Aa1," respectively.

Michigan

Economic Climate. Although Michigan's economy has diversified, it's still heavily dependent upon certain industries, especially automobile, manufacturing and related industries. Any downturn in these industries may adversely affect the economy of the state. Michigan has reported balanced budgets after substantial reductions in expenditures and some revenue enhancement. Recently, the state's economy has been affected by changes in the auto industry, notably declining Big 3 motor vehicle sales, consolidation and plant closings resulting from productivity gains, competitive pressures and over-capacity. Similar changes in the future could adversely affect state revenues and more severely affect the revenues of the municipalities, authorities and instrumentalities that have issued municipal securities.

Michigan's economy relies heavily on the performance of its durable goods manufacturing sector, especially on its cyclical auto industry. The reliance on manufacturing makes Michigan's economy more volatile than the economies of more diverse states. High unemployment remains a key issue for the state and the Economic Stabilization Fund, set up to assist the state in balancing its budget, has been largely depleted.

Michigan's economy continues to deteriorate and the protracted economic recession has caused total employment to decline for the ninth consecutive year. The state's unemployment rate is now the highest in the nation due to the severe contraction of the domestic auto and general manufacturing industry. Michigan has lost 831,500 jobs from the June 2000 peak, representing a decline of 17.7% and the unemployment rate has grown to 14.4% as of November 2009 compared to the national average of 10%. The state's consensus estimate forecasts that the unemployment rate will increase to 15.7% in 2010; close to 1.0 million jobs will have been lost before the labor market starts to normalize. Overall recovery in labor market and the economy is expected to be slow and lag the nation.

State Fiscal Matters. In 1978 the State Constitution was amended to limit the amount of total State revenues raised from taxes and other sources. State revenues (excluding federal aid and revenues for payment of principal and interest on general obligation bonds) in any fiscal year are limited to a fixed percentage of State personal income in the prior calendar year or average of the prior three calendar years, whichever is greater. The percentage is fixed by the amendment to equal the ratio of the 1978-79 fiscal year revenues to total 1977 State personal income. If any fiscal year revenues exceed the revenue limitation by one percent or more, the entire amount of such excess shall be rebated in the following fiscal year's personal income tax or single business tax. Any excess of less than one percent may be transferred to the State's Budget Stabilization Fund.

The State may raise taxes in excess of the limit for emergencies when deemed necessary by the Governor and two-thirds of the members of each house of the Legislature.

The State Constitution provides that the proportion of State spending paid to all units of local government to total State spending may not be reduced below the proportion in effect in the 1978-79 fiscal year. The State originally determined that proportion to be 41.6 percent. Effective with fiscal year 1992-93, a recalculation was made of the base year proportion as a consequence of a settlement agreement reached on the County of Oakland v. State of Michigan lawsuit, which was settled in 1991. The recalculated base year proportion is 48.97%. If such spending does not meet the required level in a given year, an additional appropriation for local governmental units is required by the "following fiscal year," which means the year following the determination of the shortfall, according to an opinion issued by the State's Attorney General. The State Constitution also requires the State to finance any new or expanded activity of local governments mandated by State law. Any expenditures required by this provision would be counted as State spending for local units of government for purposes of determining compliance with the provision cited above. Spending for local units met this requirement for fiscal years 1993-94 through 2008-09.

Tax Revenues. The state once again faced budget challenges that resulted in budget amendments and appropriation reductions during fiscal year 2009. General fund revenues from ongoing sources totaled $7.4 billion, which declined by $2.0 billion or 21.3% from fiscal year 2008. The state was able to find some additional revenue offsets and cut initial appropriations by $1.25 billion or 2.8% in fiscal year 2009. All three of the state's major governmental funds closed with a positive fund balance, totaling $1.2 billion in fiscal year 2009. The total general fund balance declined $319 million (24.7%) to $972 million, resulting from lower tax revenues and deferred spending from the prior year. The state continues to operate under thin margins as the unreserved balance fell to $177 million or 0.7% of expenditures. The School Aid Fund reported a reserve balance of $251 million while the Economic Stabilization Fund had an unreserved balance of $2.2 million in 2009.

The state also relied on the American Recovery and Reinvestment Act (ARRA) funding to blunt some of the impact to the budget over the past two fiscal years but there are only a limited amount of ARRA funds available to bridge the gap going forward. The state has been unable to replenish reserves and has had to rely on fund transfers and one time measures to balance the budget.

The state has maintained traditionally low debt levels. It ranked 32nd for debt per capita and 29th for debt to income according to Moody's 2009 State Debt Medians Report> However, contingency debt continues to rise through the Michigan Qualified School Bond Loan Fund Program. Under this program, schools can issue debt, which carries the full faith and obligation of the State of Michigan. As of September 30, 2009, the principal amount of qualified school bonds outstanding increased to $13.7 billion. Total debt service requirements on these bonds including interest is approximately $1.4 billion in 2010. The amount of loans by the state related to qualified local school district bonds under the program is $761.7 million. The state's contingent debt exposure will need to be carefully managed to maintain financial stability.

Michigan raised its income tax to 4.35% in 2007 and put in place the Michigan Business Tax on January 1, 2008.

Economic Outlook for 2009-10 and 2010-11. Legislation requires that the administration and legislative fiscal agencies prepare two economic forecasts and revenue estimates each year. These are presented to a Consensus Revenue Estimating Conference in January and May of each year. In addition, any one of the three conference principals may call a special revenue conference at any time during the year. The January 2010 conference was held on January 11, 2010.

The State's U.S. economic forecast projects the U.S. economy to grow 2.2 percent in 2010 followed by 2.7 percent growth in 2011. Light vehicle sales will rise to 11.2 million units in 2010 and then rise to 12.5 million units in 2011. The U.S. Consumer Price Index (CPI) is projected to increase 2.7 percent in 2010 and rise 2.3 percent in 2011. Ninety-day T-bill rates are expected to average 0.2 percent in 2010 and 0.9 percent in 2011.

Total Michigan wage and salary employment is projected to decrease 2.2 percent in 2010 and to decline 0.9 percent in 2011. The State's unemployment rate is projected to rise to 15.7 percent in 2010 before falling to 15.3 percent in 2011.

Michigan personal income is expected to rise 1.0 percent in 2010 and increase 1.7 percent in 2011. Prices, as measured by the Detroit CPI, are forecast to increase 2.4 percent in 2010 and rise 1.9 percent in 2011. Consequently, real (inflation adjusted) State personal income is projected to decline 1.4 percent in 2010 before falling 0.2 percent in 2011. Michigan wages and salaries are forecast to fall 1.0 percent in 2010 before rising 0.6 percent in 2011.

Litigation. The State is a party to various legal proceedings seeking damages or injunctive or other relief. In addition to routine litigation, certain of these proceedings could, if unfavorably resolved from the point of view of the State, substantially affect State programs or finances. These lawsuits involve programs generally in the areas of corrections, tax collection, commerce and budgetary reductions to school districts and governmental units. Relief sought includes damages in tort cases generally, alleviation of prison overcrowding, improvement of prison medical and mental health care and refund claims under state taxes. The State is also a party to various legal proceedings which, if resolved in the State's favor, would result in contingency gains to the State's General Fund balance, but without material effect upon Fund balance. The ultimate dispositions and consequences of all of these proceedings are not presently determinable.

Ratings of the State's Securities. As of April 19, 2010, the state's general obligation debt is rated AA- / Stable by S&P and Aa3 by Moody's with a negative outlook.

Minnesota

Economic Climate. In its November 2009 forecast, Minnesota's Office of Management and Budget projected that annual wage and salary disbursement will decline 5.5% and non-farm employment will fall 4% in 2009. This employment forecast for 2009 represents the worst annual jobs performance in terms of both percentage and total losses in the post-WWII era. Since the recession began, Minnesota's economy has lost approximately 131,000 jobs (4.7% of nonfarm employment) and the seasonally adjusted unemployment rate increased from 4.6.% in late 2007 to a peak of 8.4% in June 2009. Seasonally adjusted employment was projected to continue falling through the spring of 2010 before modest growth accelerates during the second half of the year. Measured peak-to-trough, the state will lose 154,000 jobs between the first quarter of 2008 and the first quarter of 2010, reversing over a decade's worth of job creation.

The worst recession since the 1930s, however seems to be loosening its grip on the state. While only the healthcare and social services sector continues to provide over-the-year job gains in Minnesota, last winter's deep losses in professional and business services, financial activities, retail trade, manufacturing, and mining have all moderated since mid-summer. However, despite recent improvements, Minnesota's unemployment situation remains severe and the job outlook is still grim.

Budget Process and Other Fiscal Matters. Minnesota operates on a two-year budget cycle (a biennium). The governor's biennial budget is presented to the legislature in January of odd numbered years for the upcoming biennium. State statutes and the Minnesota constitution are considered to require a balanced budget.

The assets of the State exceeded liabilities at June 30, 2008 by $13.2 billion (presented as net assets). Of this amount, $484 million was reported as unrestricted net assets. As of the end of the 2008 fiscal year, the State's governmental funds reported combined ending fund balances of $5.1 billion, a decrease of $325 million compared with the prior year. The General Fund is the chief operating fund of the State. At the end of the 2008 fiscal year, the General Fund unreserved fund balance was $689 million, while showing a $842.6 million total fund balance. The remaining governmental funds reported $2.31 billion of undesignated unreserved fund balance, which is available for spending at the government's discretion and $1.92 billion in designated fund balance. The November 2009 Office of Management and Budget forecast for the 2010-2011 biennium projected an ending deficit of $1.203 billion.

The State debt management policy currently has five guidelines. The first requires that appropriation for debt service should not exceed 3.0% of the total projected biennial General Fund non-dedicated revenues. The ratio of transfers to net non-dedicated revenues for the biennium ending June 30, 2009 is estimated at 2.69%. The second and third guidelines state that the total amount of Minnesota State general obligation bond debt should not exceed 2.5% of State personal income, and also that the total debt of State agencies should not exceed 3.5% of total personal income. The ratio of State general obligation debt to personal income for the biennium ending June 30, 2009 was estimated to be 1.98%. The total debt of State agencies was 3.03% of State personal income for the biennium 2006-2007. The fourth guideline states that the total amount of State general obligation debt, moral obligation debt, State bond guarantees, equipment capital leases and real estate leases should not exceed 5.0% of State personal income. That ratio is estimated at 1.98% for the biennium ending June 30, 2009. The fifth guideline states that 40.0% of general obligation debt shall be due within five years and 70% within ten years. As of June 30, 2009, 70.0% of the State's general obligation bonds were scheduled to mature within ten years and 40.0% were scheduled to mature within five years. Appropriation for debt service is anticipated to exceed 3.0% in the current biennium. The Department of Minnesota Management and Budget has proposed revised guidelines that would include broadening the definition of debt and emphasizing and increasing the debt to state personal income ratio guideline from 2.5% to 3.5%.

The total amount of State general obligation bonds outstanding on November 5, 2009, was approximately $5.0 billion. The total amount of general obligation bonds authorized but unissued as of November 5, 2009, was approximately $2.3 billion.

Litigation. At any given time there are numerous civil actions pending against the State of Minnesota which could, if determined adversely to the State, materially affect the State's expenditures and, in some cases, its revenues. Payment of tort claims against the State is made from funds appropriated by the Minnesota legislature to agencies for their general operations.

A material number of tort claims arose out of the August 1, 2007, Interstate Highway 35W bridge collapse, however, they may be limited by state law which set the maximum limits of limits of liability for tort claims arising in Minnesota prior to January 1, 2008, to $300,000 for any one claim and $1 million for any number of claims arising out of a single occurrence. The Minnesota legislature enacted a compensation fund and appropriated approximately $37 million to be paid to representatives of decedents and claimants who were on the bridge at the time of collapse. Claimants who accept payments must forego their right to sue the State for damages. For tort claims arising on or after January 1, 2008, the limits are raised to $400,000 for any one claim and $1.2 million for any number of claims arising out of single occurrence. For tort claims arising on or after January 1, 2009, the limits are further raised to $500,000 and $1.5 million, respectively. Lawsuits based on non-tort theories furnish another basis for liability. Included in the State's outstanding non-tort litigation are matters related to eminent domain action litigation, cigarette fees and taxes, breach of contract and corporate income taxes. Any one of these cases or classes of cases, if decided adversely, could result in an expenditure of State moneys of $15 million in excess of current expenditure levels.

Bond Ratings. As of July 29, 2010, Moody's rates Minnesota's general obligation bonds Aa1 and S&P and Fitch rate the State's general obligation bonds at AAA. There can be no assurance that such ratings will be maintained in the future. It should be noted that the creditworthiness of obligations issued by local Minnesota issuers may be unrelated to the creditworthiness of obligations issued by the State of Minnesota, and that there is no obligation on the part of the State to make payment on such local obligations in the event of default. 

North Carolina

Economic Climate. The State's estimated population as of July 1, 2009 was 9,386,573 ranking 10th in the nation. During the period from 2000 to 2009, the State's estimated population increased by approximately 16.6%. The State Demographer's Office estimates that North Carolina has eight cities with population in excess of 100,000 and two cities with populations in excess of 250,000.

According to the U.S. Bureau of Labor Statistics, North Carolina's seasonally adjusted labor force levels decreased from 4,577,313 in December of 2008 to 4,522,321 in December of 2009. Furthermore, North Carolina's total nonfarm employment accounted for only 4,016,382 jobs, reflecting a significant portion of the labor force that is likely unemployed, largely due to the economic recession that began in December of 2007. There are 191,258 less workers employed in North Carolina compared to the same time last year. North Carolina ranks ninth among the fifty states for both total nonfarm employment and manufacturing sector employment. The State's major industry sectors are services, agriculture, trade, manufacturing, exports and tourism. During the period from 1999 to 2009, per capita income in the State grew from $24,473 to $34,711, an increase of 10.6% when adjusted for inflation.

North Carolina's seasonally adjusted unemployment rate in December was 11.2% compared to 10% for the nation as a whole. North Carolina's December unemployment rate surpassed the previous historic high of 11.1% (May 2009), ending a string of six consecutive months where unemployment either improved slightly or remained relatively the same. The state's unemployment rate is 3.1 percentage points higher when compared to the same month a year ago (December 2008) and 6.2 percentage points higher than at the start of the recession. Compared to last year (December 2008), North Carolina has lost approximately 124,200 nonfarm payroll jobs, a 3.1% decline. Since the start of the recession in December 2007, North Carolina's total non farm employment has decreased by 248,000 (5.9% of the nonfarm workforce). Sectors with the most employment decline since December 2007 are: Manufacturing (-95,500); Construction (-65,800); Trade, Transportation & Utilities (-59,900); and Professional & Business Services (-37,400). Two sectors have experienced gains, Education & Health Services (+6,700) and Government (+17,400).

Budget Process. The State Constitution in Article III, Section 5 details the duties of the Governor to prepare and recommend to the General Assembly a comprehensive budget of anticipated revenue and proposed expenditures of the State for the ensuing fiscal period. Furthermore, once a budget is enacted by the General Assembly, the Governor is required to administer this budget and ensure that the State does not incur a deficit during any fiscal period. To comply with this mandate the Governor must survey the collection of revenue and shall effect the necessary economies in the State expenditures whenever she determines that receipts during the fiscal period in question, when added to the beginning unreserved General Fund balance, will not be sufficient to meet budgeted expenditures. The State Budget Act ("SBA") sets out the procedures by which the State's budget is prepared, adopted and administered. The SBA requires the adoption of a balanced budget and G.S. 143C-4-1 provides guidance as to what constitutes a balanced budget. A budget for a fund is balanced when the beginning unreserved fund balance for a fiscal year, together with the projected receipts to the fund during the fiscal year, is equal to or greater than the sum of appropriations from the fund for that fiscal year. If the Governor finds that revenues to any fund, when added to the beginning unreserved fund balance in that fund, will be insufficient to support appropriations, the Governor shall immediately notify the General Assembly that a deficit is anticipated. Furthermore, the Governor shall report in a timely manner to the General Assembly a plan containing the expenditure reductions and other lawful measures that are to be implemented to avert a deficit. However, the North Carolina Constitution provides that any such reduction in appropriations to avert a deficit shall be made "after first making adequate provision for the prompt payment of the principal of and interest on bonds and notes of the State according to their terms."

The total State budget is supported from four primary sources of funds: (1) General Fund tax and non-tax revenue; (2) Highway Fund and Highway Trust Fund tax and non-tax revenue; (3) federal funds and (4) other receipts, generally referred to as departmental receipts. Federal funds compromise approximately 33.1% of the total State budget for fiscal year 2009-2010. The largest share of federal funds is designated to support programs of the Department of Health and Human Services. The other major recipients of federal funds are public schools, universities, community colleges and transportation, including highway construction and safety.

All funds presented to and reviewed by the General Assembly and approved in accordance with its procedures are considered "appropriated" or authorized by the General Assembly.

State Revenues and Expenditures. As of the end of the fiscal year, the State's governmental funds reported combined ending fund balances of $2.889 billion, a decrease of 48.97% from the prior fiscal year-end (as restated). The primary contributor to the decline was the General Fund, which had a $2.454 billion decrease in fund balance in 2009. The substantial decrease in total fund balance of governmental funds was partially offset by the receipt of federal recovery funds, primarily in the General Fund, and by unspent debt proceeds reported in other governmental funds. The State issued debt in the current fiscal year for the state and university capital improvement projects.

The General Fund is the chief operating fund of the State. The fund balance of the General Fund declined substantially from $1.678 billion at June 30, 2008 (as restated) to negative $775.864 million at June 30, 2009. For fiscal year 2009, the State appropriated most of the beginning unreserved fund balance, appropriated $1.155 billion of federal recovery funds, reduced expenditures, and transferred amounts from other funds (and statutory reserves) to finance a General Fund revenue shortfall (excess of total expenditures over total revenues) of $2.983 billion. Despite the receipt of federal recovery funds, total revenues of the General Fund decreased for the first time in seven years. General Fund tax revenues decreased dramatically. A sharp rise in the State's unemployment rate contributed to a 2% decline in withholding tax payments by employers and a 31.1% decline in final income tax payments by taxpayers. Refunds of individual income taxes increased 13.8%. Additionally, the tax rate on higher income taxpayers was reduced from 8% to 7.75% for tax year 2008. Corporate income taxes which are, highly volatile over the business cycle, decreased by 25.61%. Even with a rise in the State sales and use tax from 4.25% to 4.5%, effective October 1, 2008, sales and use tax revenues decreased by 4.94%. The rise in the State unemployment rate contributed to a downturn in consumer spending. The housing sector was impacted most by the decline.

Because of recessionary economic conditions in the nation and North Carolina, the Governor became aware that actual receipts for the current fiscal year would not meet expenditures anticipated and budgeted by the 2008 General Assembly. Accordingly, on January 13, 2009, the Governor issued Executive Order No. 6, Budget Administration Due to National Economic Slowdown, to ensure that a deficit was avoided. Executive Order No. 6 ordered the Office of State Budget and Management to do the following: 1) reduce, as necessary, State expenditures from funds appropriated to operate State departments and institutions, resulting in reversions of $1.7 billion, 2) halt expenditures for capital improvement projects for which State funds have been appropriated but not placed under State contract, resulting in reversions of $175.9 million ( 40 million was also transferred from capital improvement projects that were completed but had unexpended funds), 3) transfer, as necessary, non-General Fund and non-Highway Fund receipts into the General Fund to support appropriation expenditures, which included $386.6 million from the Rainy Day Fund, $337.5 million of cash balances from other funds, and $10.1 million from three other statewide reserves, and 4) other steps as specified in Order.

Actual total revenue collected (both tax and non-tax) was significantly below budgeted amounts in fiscal year 2008-09. Similar to the experience in many other states, the December 2008 recession caused unprecedented declines in North Carolina's revenue collections. While North Carolina's revenue forecast anticipated a slowdown, it did not expect a financial major market collapse and major recession. This translated into historic declines in sales and use tax collections and individual income tax collections, North Carolina's two largest revenue sources.

Litigation. The following are cases pending in which the State faces the risk of either a loss of revenue or an unanticipated expenditure. Although an adverse result in any of the cases could have negative budgetary consequences, in the opinion of the Department of State Treasurer after consultation with the Attorney General, an adverse decision in any of these cases would not materially adversely affect the State's ability to meet its financial obligations.

Hoke County et al, v. State of North Carolina and State Board of Education - Right to a Sound Basic Education (formerly Leandro). In 1994, students and boards of education in five counties in the State filed suit in Superior Court requesting a declaration that the public education system of North Carolina, including its system of funding, violates the State constitution by failing to provide adequate or substantially equal educational opportunities, by denying due process of law, and by violating various statutes relating to public education. Five other school boards and students therein intervened, alleging claims for relief on the basis of the high proportion of at-risk and high-cost students in their counties' systems.

The suit is similar to a number of suits in other states, some of which resulted in holdings that the respective systems of public education funding were unconstitutional under the applicable state law. The State filed a motion to dismiss, which was denied. On appeal, the North Carolina Supreme Court upheld the present funding system against the claim that it unlawfully discriminated against low wealth counties, but remanded the case for trial on the claim for relief based on the Court's conclusion that the constitution guarantees every child the opportunity to obtain a sound basic education. Trial on the claim of one plaintiff-county was held in the fall of 1999. On October 26, 2000 the trial court, in Section Two of a projected three-part ruling, concluded that at-risk children in North Carolina are constitutionally entitled to such pre-kindergarten educational programs as may be necessary to prepare them for higher levels of education and the "sound basic education" mandated by the Supreme Court. On March 26, 2001, the Court issued Section Three of the three-part ruling, in which the judge ordered all parties to investigate certain school systems to determine why they are succeeding without additional funding. The State filed a Notice of Appeal to the Court of Appeals, which resulted in the Court's decision to re-open the trial and call additional witnesses. That proceeding took place in the fall of 2001. On April 4, 2002 the Court entered Section Four of the ruling, ordering the State to take such actions as may be necessary to remedy the constitutional deficiency for those children who are not being provided with access to a sound basic education and to report to the Court at 90-day intervals remedial actions being implemented. On July 30, 2004, the North Carolina Supreme Court affirmed the majority of the trial court's orders, thereby directing the executive and legislative branches to take corrective action necessary to ensure that every child has the opportunity to obtain a sound, basic education. The Supreme Court did agree with the State that the trial court exceeded its authority in ordering pre-kindergarten programs for at-risk children. The State is now undertaking measures to respond to the trial court's directives. The magnitude of State resources which may ultimately be required cannot be determined at this time, however, the total cost could exceed $100 million.

N.C. School Boards Association, et al. v. Richard H. Moore, State Treasurer, et. al, Use of Administration Payments. On December 14, 1998, plaintiffs, including county school boards of Wake, Durham, Johnston, Buncombe, Edgecombe and Lenoir Counties, filed suit in Superior Court requesting a declaration that certain payments to State administrative agencies must be distributed to the public schools on the theory that such amounts are civil penalties which under the North Carolina Constitution must be paid to the schools.

On December 14, 2001, the Superior Court of Wake County granted summary judgment in favor of the plaintiffs on all issues, concluding that the funds in dispute are civil fines or penalties required By Article IX, Section 7 of the Constitution to he remitted to the public schools in the county where the violation occurred. The court further determined a three-year statute of limitations to be applicable, making the order retroactive to December 1995. This case was argued in the Court of Appeals in February, 2003. The North Carolina Court of Appeals rendered a decision in September 2003 substantially favorable to the State. On July 1, 2005 the Supreme Court reversed the Court of Appeals in part, concluding that a majority of the funds in dispute are civil penalties required to be paid into the Civil Penalty and Forfeiture Fund for the benefit of public schools. The case was remanded to Superior Court and on August 8, 2008 the Superior Court entered a judgment in the amount of $749.886 million. The court acknowledged, however, that the judicial branch did not have the power to force the State to satisfy the judgment and that any decision to do so would have to come from the legislature.

Southeast Compact Commission - Disposal of Low-level Radioactive Waste. North Carolina and seven other southeastern states created the Southeast Interstate Low-level Radioactive Waste Management Compact to plan and develop a site for the disposal of low-level radioactive waste generated in the member states. North Carolina was assigned responsibility for development of the first disposal site, with costs to be distributed equitably among the Compact members. In 1997 the Compact Commission discontinued funding of the development of the North Carolina site, alleging that the State was not actively pursuing the permitting and development of the proposed site. North Carolina withdrew from the Compact in 1999. The Compact subsequently asked the United States Supreme Court to accept its Complaint against North Carolina demanding the repayment, with interest, of $80 million of Compact payments expended on the permitting of the site, plus $10 million of future lost income, interest and attorney fees. The Supreme Court denied this motion in August 2001. On August 5, 2002 the Compact, with the addition of four member states as plaintiffs, filed a new motion requesting the United States Supreme Court to accept the claim under its original jurisdiction. On June 16, 2003, the Court accepted jurisdiction of the case and the State filed an answer and motion to dismiss on August 21, 2003. On November 17, 2003, the U.S. Supreme Court appointed a Special Master with authority to receive evidence and make recommended rulings on the issues presented by the case. On April 2, 2009, the Special Master filed his "Preliminary Report" and his "Second Report" recommending that the Court dismiss the claims seeking enforcement of the monetary sanction imposed against North Carolina by the Compact Commission as well as the entry of partial summary judgment finding that North Carolina did not breach the Compact when it withdrew. Briefing by the parties on Exceptions to the Reports of the Special Master concluded on September 9, 2009. The United States Supreme Court heard oral arguments on January 11, 2010.

State Employees Association of North Carolina v. State; Stone v. State - Diversion of Employer's Retirement System Contribution. On May 22, 2001, SEANC filed an action in Wake County Superior Court demanding repayment of approximately $129 million in employer retirement contributions to the Retirement Systems. The Governor withheld, and subsequently used, the withheld funds under his constitutional authority to balance the State budget. The trial court dismissed the action on May 23, 2001, and the North Carolina Court of Appeals affirmed this dismissal on December 3, 2002. The Supreme Court, on June 13, 2003, reversed the Court of Appeals on issues related to class standing and remanded with instructions to consider procedural issues raised but not addressed by the Court of Appeals. The Court of Appeals remanded the case to the Superior Court of Wake County without opinion and without considering any remaining issues.

In June 2002, the Stone case was filed in Wake County Superior Court on behalf of individual State employees and retirees seeking repayment of the withheld employer contribution and a prohibition against future diversions. A class comprised of all members of the Retirement System has been certified and the case is currently proceeding through class notification and toward trial. On September 6, 2006, the trial court issued an interlocutory order in response to cross-motions for summary judgment. The court's order found the diversion of funds to be in violation of the constitution, but did not direct any repayment of funds, reserving the question of repayment for consideration, if necessary after appeal of the constitutional issues. On August 5, 2008 the Court of Appeals affirmed the Superior Court order. Both sides gave notice appeal and filed petitions for discretionary review with the North Carolina Supreme Court. On June 17, 2009, the Supreme Court dismissed the appeals and denied the petitions for discretionary review.

The case now returns to the Superior Court for consideration of damages. Because the General Assembly has repaid the principal amount withheld from the Retirement System, consideration will focus on lost interest and earnings, if any. A new judge will need to be appointed to hear the case, as the judge previously assigned to the case is now employed by the North Carolina Department of Transportation.

Goldston v. State of North Carolina - Highway Trust Fund Transfers. On November 14, 2002, a lawsuit was filed in Wake County Superior Court demanding that $80 million transferred by the Governor from the Highway Trust Fund to the General Fund for purposes of balancing the State budget be returned to the Highway Trust Fund. The suit further alleges that actions of the General Assembly regarding the transfer of funds from the Highway Trust Fund to the General Fund constitute a borrowing by the State of Highway Trust Fund cash surplus and are unlawful and unconstitutional. The lawsuit requests a declaration that taxes collected for purposes of Highway Trust Fund expenditures cannot be used for other purposes. Summary Judgment was granted in favor of the State on all issues and Plaintiff has filed a notice of appeal. On September 20, 2005, the North Carolina Court of Appeals upheld the trial court's order. The plaintiff filed a petition for discretionary review with the North Carolina Supreme Court, and the Court agreed on March 2, 2006 to review a portion of the Court of Appeals' decision and oral argument was heard on October 16, 2006. In an opinion filed December 15, 2006, the Supreme Court reversed the Court of Appeals, concluding that plaintiffs have standing to pursue their claims. On remand to Wake County Superior Court, the court ruled in favor of the State on both the standing argument and the merits of the case. Plaintiffs appeal was argued in the Court of Appeals on January 28, 2009. In an opinion filed September 15, 2009 the Court of Appeals held that although the General Assembly had the authority to transfer $125 million from the Highway Trust Fund to the General Fund, the Governor exceeded his constitutional authority in transferring $80 million from the Highway Trust Fund to the General Fund. The State has appealed this decision to the North Carolina Supreme Court.

State of North Carolina v. Phillip Morris, Inc., et al., 98 CVS 14377- Master Settlement Agreement ("MSA") Payments. On April 20, 2006, the State of North Carolina filed a Motion for Declaratory Order in the North Carolina Business Court against defendants Phillip Morris, Inc., R.J. Reynolds Tobacco Company, and Lorillard Tobacco Company. The Motion is seeking a declaration that (1) in 2003, North Carolina continuously had a Qualifying Statute in full force and effect and "diligently enforced" its provisions throughout that year in accordance with the MSA; (2) North Carolina is not subject to a Non-Participating Manufacturers' Adjustment for 2003; and (3) defendants are obligated not to withhold or pay into a disputed payments account any payments due, or seek any offset of any payments made, on the basis that North Carolina is subject to a Non-Participating Manufacturers' Adjustment for 2003. If the State is unable to ultimately prevail in the diligent enforcement litigation, the State may be unable to recover a portion of this year's MSA payment. On December 4, 2006, Judge Tennille allowed the defendant's motion to compel arbitration of these issues. The Court of Appeals upheld the Order, and the State's Petition to the North Carolina Supreme Court has been denied. The State is therefore now participating in a national arbitration process with the tobacco companies and all other MSA States.

Pendergraph v. North Carolina Department of Revenue - Refund of Income Taxes. Taxpayers have filed a class action complaint and petition for judicial review with the North Carolina Business Court for a refund of income taxes. Taxpayers are pursuing a constitutional challenge to N.C. Gen. Stat. § 128-31 (1988), N.C. Gen. Stat. § 135-9 (1988) and N.C. Gen. Stat. § 105-134.6 (1988) which repealed the tax exemptions for state and local retirement benefits and subjected all state, local and federal benefits above $4,000 to tax. These amendments became effective for taxable years beginning on or after January 1, 1989. The Department of Revenue has filed a motion to dismiss, which is currently pending before the court. The amount at issue is not readily calculable, but it is likely to be in excess of $20 million dollars.

Other Litigation. The State is involved in numerous other claims and legal proceedings, many of which are normal for governmental operations. A review of the status of outstanding lawsuits involving the State by the North Carolina Attorney General did not disclose other proceedings that are expected to have a material adverse effect on the financial position of the State.

Bond Ratings. As of March 2010, Standard & Poor's had rated the State's general obligation bonds "AAA," Moody's had rated those bonds "Aaa" and Fitch had rated those bonds "AAA". 

Ohio

Economic Climate. Ohio is the seventh most populous state. The Census count for 2000 was 11,353,100, up from 10,847,100 in 1990. While diversifying more into the service and other non manufacturing areas, the Ohio economy continues to rely in part on durable goods manufacturing largely concentrated in motor vehicles and machinery, including electrical machinery. As a result, general economic activity, as in many other industrially developed states, tends to be more cyclical than in some other states and in the nation as a whole. Agriculture is an important segment of the economy, with over half the State's area devoted to farming and a significant portion of total employment in agribusiness.

In earlier years, the State's overall unemployment rate was commonly somewhat higher than the national figure. For example, the reported 1990 average monthly State rate was 5.7%, compared to the 5.5% national figure. However, then through 1998 the annual State rates were below the national rates (4.3% vs. 4.5% in 1998), were again slightly higher in 1999 (4.3% vs. 4.2%) and 2000 (4.0% vs. 4.0%), lower in 2001 (4.4% vs. 4.7%) and in 2002 (5.7% vs. 5.8%) and higher in 2003 (6.2% vs. 6.0%), in 2004 (6.1% vs. 5.5%), in 2005 (5.9% vs. 5.1%), in 2006 (5.5% vs. 4.6%), in 2007 (5.6% vs. 4.6%) and in 2008 (6.6% vs. 5.8%). In November 2009, the State unemployment rate was higher than the national rate (10.6% vs. 10.0%). The unemployment rate and its effects vary among geographic areas of the State.

Budget Process and Budgets. The State operates on the basis of a fiscal biennium for its appropriations and expenditures, and is effectively precluded by law from ending its July 1 to June 30 fiscal year (FY) or fiscal biennium in a deficit position. Most State operations are financed through the General Revenue Fund (GRF), for which the personal income and sales use taxes are the major sources. Growth and depletion of GRF ending fund balances show a consistent pattern related to national economic conditions, with the ending FY balance reduced during less favorable and increased during more favorable economic periods. The State has well established procedures for, and has timely taken, necessary actions to ensure resource/expenditure balances during less favorable economic periods such as the current fiscal biennium. Those procedures include general and selected reductions in appropriations spending.

The appropriations acts for the 2010-11 biennium include all necessary appropriations for debt service on State obligations and for lease payments relating to lease rental obligations issued by the Ohio Building Authority and the Treasurer of State, and previously by the Ohio Public Facilities Commission.

The following is a selective general discussion of State finances, particularly GRF receipts and expenditures, for the recent and the current bienniums. As evidenced by actions discussed, the State administrations and both houses of the General Assembly have been and are committed to and have taken and are taking actions that ensure a balance of GRF resources and expenditures.

2008-09 Budget. Ongoing and rigorous consideration was given by the Governor and the General Assembly to revenues and expenditures throughout Fiscal Years 2008-09, primarily as a result of the Ohio economy being negatively affected by the national economic downturn. Budgetary pressures during this period were primarily due to continuing lower than previously estimated levels of receipts from certain major revenue sources.

Consideration came in three general time frames - winter 2007, fall/winter 2008, and spring 2009. Significant measures were taken including use of the entire Budget Stabilization Fund (BSF) balance and expenditure reductions and spending controls on State agencies and departments.

Consistent with State law, the Governor's Executive Budget for the 2008-09 biennium was released in March 2007 and introduced in the General Assembly. After extended hearings and review, the GRF appropriations Act for the biennium was passed by the General Assembly and signed (with selective vetoes) by the Governor on June 30, 2007. Reflecting the continued implementation of the restructuring of State taxes commenced in 2006-07, that Act was based upon then estimated total GRF biennial revenues of approximately $53.5 billion (a 3.9% increase over the 2006-07 biennial revenue) and total GRF biennial appropriations of approximately $52.4 billion (a 2.1% increase over the 2006-07 biennial expenditures). Spending increases for major program categories over the 2006-07 actual expenditures were: 2.2% for Medicaid (the Act also included a number of Medicaid reform and cost containment initiatives); 13.2% for higher education; 5.2% for elementary and secondary education; 4.9% for corrections and youth services; and 4.7% for mental health and mental retardation. The Executive Budget and the GRF appropriations Act complied with the law discussed above under 2006-07 limiting appropriations for the 2008-09 biennium. The Executive Budget, the GRF appropriations Act and the separate appropriations acts for the biennium included all necessary debt service and lease rental payments related to State obligations.

• With the Ohio economy expected to be negatively affected by the national economic downturn, in January 2008 OBM reduced its original GRF revenue projections by $172.6 million for Fiscal Year 2008 and $385.1 million for Fiscal Year 2009. Based on those lower GRF revenue estimates and increased costs associated with rising Medicaid caseloads, OBM projected a budgetary shortfall for the 2008-2009 biennium of $733 million. Executive and legislative actions implementing expenditure reductions and spending controls, re-allocation of funds, and expansion of the state run lottery system were taken based on the new OBM estimates.

In June 2008, the General Assembly also passed legislation that provided for, among other things, transfers to the GRF (after a selective line-item veto) of up to $63.3 million from the BSF for the State's share of increased Medicaid costs, $55 million from rotary funds and $25 million in uncommitted interest earnings from proceeds of the State's Tobacco Settlement Asset-Backed Bonds.

In March 2008, in response to the national economic downturn, the Governor proposed a $1.7 billion economic stimulus plan to stimulate the Ohio economy through investments in logistics and distribution, bio-products and bio-medical research, advanced and renewable energy, local government infrastructure, conservation projects and brownfield revitalization projects. These investments were to be funded primarily through new GRF bond-backed capital appropriations. After extensive hearings and review, the General Assembly in June passed a $1.57 billion economic stimulus package that mirrored the purposes proposed by the Governor and added funding for higher education workforce programs and expanded the State's historic preservation tax credits. The sources of funding for the stimulus plan include, in addition to GRF-backed bonds, $230 million of cash from the Ohio Tobacco Prevention Foundation (this transfer is subject to a pending legal challenge), $370 million in GRF operating appropriations to have been made over the next five fiscal years, $184 million in bonds backed by net profit from the State's liquor enterprise, and $200 million in bonds backed by highway user receipts.

With the Ohio economy continuing to be negatively affected by the national economic downturn, OBM on September 10, 2008 announced a $540 million further reduction in its GRF revenue projections for Fiscal Year 2009 and a projected Fiscal Year budgetary shortfall of the same amount. Executive actions announced to offset the projected shortfall.

On December 1, 2008, OBM announced a further $640.4 million reduction in GRF revenue projections for Fiscal Year 2009 expected to result in a projected Fiscal Year budgetary shortfall of the same amount. Executive actions announced to offset much of that projected shortfall. Based on implementation of certain expenditure reductions, spending controls and other measures - and before the revised revenue estimates referred to below - OBM was projecting a positive GRF fund balance at June 30, 2009. Based on the Administration's continuing monitoring of revenues, and as an anticipated step in the then ongoing 2010-11 biennial budget and appropriations process, OBM reported revised revenue estimates to the General Assembly on June 11, 2009. Those estimates revised Fiscal Year 2009 revenues downward by an additional $912 million over OBM's December 2008 adjusted baseline, based primarily on updated income and sales tax receipts through May 31. To address this additional Fiscal Year 2009 revenue shortfall, the Governor received General Assembly approval for and used the entire remaining BSF balance of $949 million for Fiscal Year 2009.

The State ended Fiscal Year 2009 with GRF cash and fund balances of $734.5 million and $389.1 million respectively, and a $-0- balance in the BSF. Of the ending GRF fund balance, $133.4 million represents the one-half of one percent of Fiscal Year 2009 GRF revenues the State is required to maintain as an ending fund balance.

Current Biennium. Consistent with State law, the Governor's Executive Budget for the 2010-11 biennium was released in February 2009 and introduced in the General Assembly. After extended hearings and review, and after passage by the General Assembly and signing by the Governor of three seven-day interim budgets, the 2010-11 biennial appropriations Act was passed by the General Assembly and signed (with selective vetoes) by the Governor on July 17, 2009. All necessary debt service and lease-rental payments related to State obligations for the entire 2010-11 biennium were fully appropriated for the three week interim period and under the final Act. Reflecting the final implementation of the restructuring of State taxes commenced in 2006-07 and a conservative underlying economic forecast, that Act makes total GRF biennial appropriations of approximately $50.5 billion (a 3.8% decrease from the 2008-09 biennial expenditures) based on GRF biennial estimated revenues of approximately $51.1 billion (a 4.2% decrease from the 2008-09 biennial revenues). Appropriations for major program categories compared to 2008-09 actual spending reflect increases of 3.4% for Medicaid (that Act also included a number of Medicaid reform and cost containment initiatives) and 0.7% for corrections and youth services; and decreases of 13.8% for mental health and developmental disabilities, 8.3% for higher education, and 5.15% for elementary and secondary education. That Act also includes the restructuring of $736 million of Fiscal Years 2010 and 2011 general revenue fund debt service into Fiscal Years 2012 through 2025. Both the Executive Budget and the GRF appropriations Act complied with the law discussed above under 2006-07 limiting most GRF appropriations.

Major new or recurring sources of revenues reflected in the 2010-11 appropriations Act include, among other things:

• $2.4 billion of "Federal Stimulus" funding received under the American Recovery and Reinvestment Act of 2009, including $1.464 billion for elementary and secondary education, $628 million for Federal Medical Assistance Payments, and
  $326 million for other purposes. 

• $933 million in gaming and license revenues ($296 million in Fiscal Year 2010 and $637 million in Fiscal Year 2011) from the Ohio Lottery Commission's implementation of video lottery terminals (VLTs) at the seven horse racing tracks in the State. OBM estimated the VLTs would result in an approximately $851 million net increase in revenues for the biennium ($285 million in Fiscal Year 2010 and $566 million in Fiscal Year 2011) after taking into account offsetting effects of the VLTs on other lottery revenues. On September 21, 2009, the Ohio Supreme Court ruled that the statutory provisions enacted in the biennial appropriations Act in support of implementation of those VLTs are subject to voter referendum and granted petitioners in that case until December 20, 2009 to submit referendum petitions with valid signatures of at least six per cent of the electors of the State (approximately 241,000). Under the referendum provisions of the Ohio Constitution, if referendum petitions with sufficient valid signatures are submitted by December 20, those statutory provisions for VLTs will not take effect "unless and until approved by a majority of those [electors] voting upon the same." The Ohio Secretary of State's office has stated that if petitions with sufficient valid signatures are submitted by the December 20 deadline, the referendum election would be held on November 2, 2010. 

• $259 million from the Ohio Tobacco Use Prevention and Control Foundation Endowment Fund (TUPAC) to be deposited into a special State fund (non-GRF) to be used for various health care initiatives. On August 11, 2009, a trial court ruled in favor of the plaintiffs and ordered these monies must remain in that endowment fund and be used for the purpose of reducing tobacco use. The State immediately appealed this trial court ruling and on December 31, 2009, the Court of Appeals ruled in favor of the State and reversed the trial court's order. Plaintiffs in the trial court have announced they will appeal the Court of Appeals decision to the Ohio Supreme Court.

In response to the above-referenced September 21 decision of the Ohio Supreme Court declaring the VLT provisions in the biennial appropriations Act subject to referendum, the Governor proposed for General Assembly consideration postponing for two years the final installment of the personal income tax reduction currently scheduled to take effect for tax year 2009 (for returns filed in 2010). After extended hearings and review, the General Assembly approved, and the Governor signed into law on December 22, 2009, legislation keeping personal income tax rates at 2008 levels through tax year 2010. The Ohio Department of Taxation estimates the postponement will result in $844 million of additional State GRF tax revenues in the current biennium ($418 million in Fiscal Year 2010 and $426 million in Fiscal Year 2011). OBM is currently projecting a positive GRF fund balance at the end of each Fiscal Year and biennium.

Litigation. The state is a party to various legal proceedings seeking damages or injunctive relief and generally incidental to its operations, but unrelated to the security for the bonds. The ultimate disposition of these proceedings is not presently determinable, but in the opinion of the Ohio Attorney General will not have a material adverse effect on the Bonds or the security for the Bonds.

Bond Ratings. As of March 23, 2010, the State's general obligation bonds were rated Aa2, AA+ and AA by Moody's, S&P and Fitch, respectively. The Moody's and Fitch ratings reflect recent downgrades. On June 10, 2009, Fitch downgraded the State's general obligation credit rating to AA from AA+ and revised its credit outlook associated with the rating to stable from negative. On June 15, 2009, Moody's downgraded the State's general obligation credit rating to Aa2 from Aa1 and, on August 24, 2009, revised its rating outlook associated with the rating to negative from stable. On September 23, 2009, S&P revised its rating outlook associated with the rating to negative from stable.

Virginia

Economic Climate. The Commonwealth's 2008 population of 7,769,089 was 2.6% of the United States' total. Among the 50 states, it ranked twelfth in population. With 39,594 square miles of land area, its 2008 population density was 196.2 persons per square mile, compared with 95.66 persons per square mile for the United States.

The Commonwealth is divided into five distinct regions--a coastal plain cut into peninsulas by four large tidal rivers, a piedmont plateau of rolling farms and woodlands, the Blue Ridge Mountains, the fertile Shenandoah Valley and the Appalachian plateau extending over the southwest corner of the Commonwealth. Approximately one-third of all land in Virginia is used for farming and other agricultural services. This variety of terrain, the location of the Commonwealth on the Atlantic Seaboard at the southern extremity of the northeast population corridor and its close proximity to the nation's capital have had a significant influence on the development of the present economic structure of the Commonwealth.

The largest metropolitan area is the Northern Virginia portion of the Washington-Arlington-Alexandria MSA (Metropolitan Statistical Area).. This is the fastest growing metropolitan area in the Commonwealth and had a 2008 population of 5,358,130 (including Washington and Maryland's population of 1,768,234). Northern Virginia has long been characterized by the large number of people employed in both civilian and military work with the federal government. It is also one of the nation's leading high-technology centers for computer software and telecommunications.

According to the U.S. Department of Commerce, Virginians received over $333.1 billion in estimated personal income in 2008. In 2008, Virginia had per capita income of $42,876, the highest of the Southeast region and greater than the national average of $39,751. From 1998 to 2007, the Commonwealth's 4.4% average annual rate of growth in personal per capita income was more than the national growth rate of 4.0%. 

As of June 2008, more than 4.0 million residents of the Commonwealth were in the civilian labor force, which includes agricultural and nonagricultural employment, the unemployed, the self-employed and residents who commute to jobs in other states.

Employment in the Information Services sector decreased from 90,400 to 87,600 jobs. This is due in part to the intense telecommunications competition. The Professional and Business Services sector added 8,800 or 1.4 percent in 2008. Growth in this sector was mainly concentrated in Northern Virginia, the state's largest metropolitan area, but this industry also saw gains in most of the state's other metropolitan areas. The private Education and Health sector continued to add jobs in 2008, and increased 18.4 percent over the five year period. Similarly, the Leisure and Hospitality sector showed growth by 13% over the same period.

The Financial Activities employment of 188,800 was 4,900 or 2.6 percent below it June 2007 level. Problems in the mortgage banking, credit, and brokerage subsectors contributed to the decrease in job totals. Construction employment decreased to 222,200 or 7.4 percent below the 2007 average of 239,900. The slump in home building was a significant factor in the reduction. Total Government employment increased by 11,600 workers or 1.7 percent in 2008. Wholesale and retail trade had a decrease of 1,900 jobs in 2008, a 1.55 percent decrease from 2007. National Resources and Mining employment in Virginia had a slight increase by 200 jobs in 2008, to 11,100. Manufacturing employment decreased by 13,300 jobs or 4.8 percent. The loss was mostly in the durable goods subsection where employment was down 9,500, or 5.8 percent. Employment in the non durable goods subsection was down 3,600 or 3.1 percent.

During 2008, an average of 4.0% of the Commonwealth's population was unemployed, compared to 5.8% for the nation.

Budgetary Process. The Governor is required by statute to present a bill detailing his budget (the "Budget Bill") and a narrative summary of the bill to the General Assembly by December 20th in the year immediately prior to each even-year session. Under constitutional provisions, the Governor retains the right, in his review of legislative action on the Budget Bill, to suggest alterations to or to veto appropriations made by the General Assembly. After enactment, the Budget Bill becomes law (the "Appropriation Act"). In the odd-year sessions of the General Assembly, amendments are considered to the Appropriation Act enacted in the previous year. The Governor submits a Budget Bill by December 20th that includes his proposed amendments. The Appropriation Act enacted in the odd-year session is effective upon passage by the General Assembly, whereas the regular biennial Appropriation Act is effective July 1, the beginning of the biennium.

The 2008 Appropriation Act. On December 17, 2007, Governor Kaine presented the 2008 Budget Bill for the 2008-2010 biennium. The 2007 Budget Bill was developed with the following four main objectives in mind:

• Maintain the Commonwealth's financial stability for the long term;

• Make targeted investments that will pay measurable returns in the future;

• Meeting the Commonwealth's ongoing commitment to fund core services; and 

• Use program preference, financial incentives, and operation streamlining to promote better government

The 2008 Budget Bill included $36,174.3 million from the general fund in base spending, and total general fund resources of $36,197.7 million. Recommendations for new spending totaled $2,213.6 million, including $54.0 million for capital outlay funding. General fund budget savings of $463.6 million were also recommended.

Major items in the 2008 Budget Bill recommended to meet the Commonwealth's commitment to fund core services included $890.3 million for estimated state cost of the technical re-benchmarking of the Standards of Quality for elementary and secondary schools and $254.7 million for a proposed salary increase for state and state-supported local employees, teachers and teaching and research facility at higher education institutions.

Other proposed spending items included $29.2 million to expand the existing Virginia Preschool Initiative serving at-risk students; $14.5 million to increase community services board emerging services capacity; $4.9 million in improvements aimed at offender reentry; $38.1 million in semiconductor manufacturing performance grants; and $15.1 million in the Governor's Development Opportunity Fund. A Revenue Stabilization Fund deposit of $21.3 million in the fiscal year 2009 based on actual tax revenues for fiscal year 2007 was included. 

The Virginia General Assembly sent an amended budget to the Governor on March 13, 2008. The budget retained many of the items the Governor introduced. Highlights of the House and Senate conference report included: the funding for certain capital projects from Virginia Public Building Authority/Virginia College Building Authority debt; 2 percent salary increase in both years for state employees and state-supported local employees; 2 percent salary increase for teachers on July 1, 2009; $22 million to increase the per pupil amount for the preschool initiative for disadvantaged four-year olds; $41.6 million for 600 new Mental Retardation waivers in FY 2009; almost $11.1 million per year for base adequacy institutions of higher education; retaining $15.1 million for the Governor's Opportunity Fund; and providing $30 million in bond funding to be used for acquisition of open space lands, historic sites, and civil war battlefield preservation. 

The Governor returned the budget bill requesting 41 amendments, primarily technical in nature. The General Assembly accepted 34 of these amendments. On May 23, 2008 the Governor signed the Budget Bill with on veto, and the Budget Bill was enacted as Chapter 879 of the 2008 Virginia Acts of Assembly. The bill became effective July 1, 2008 (the "2008 Appropriation Act"). 

The 2009 Amendments to the 2008 Appropriation Act. On December 17, 2008, Governor Kaine presented his proposed amendments to Chapter 879, the 2008 Virginia Acts of Assembly (House Bill 1600/Senate Bill 850) (the "2009 Budget Bill") affecting the remainder of the 2008-2010 biennium. The Governor's objectives were developed with the following goals in mind: maintain the Commonwealth's financial stability for the long term; make targeted investments that will enhance Virginia's ability to compete in a global economy; and meet the Commonwealth's ongoing commitment to fund core services.

The 2009 Budget Bill included the most recent rounds of executive branch cuts to balance the $2.9 billion revenue shortfall from the budget bill approved during the 2008 Session. Governor Kaine revealed his reduction plan in October for the remainder of fiscal year 2009 and proposed his reductions for fiscal year 2010 on December 17, 2008. The 2009 Budget Bill proposed a withdrawal of $490 million from the Revenue Stabilization Fund to balance the budget for fiscal year 2009. The 2009 Budget Bill did not rely on the Revenue Stabilization Fund to balance fiscal year 2010, so it remains available in 2010 if there is any further slowing in the economy. 

There were several spending initiatives proposed in the budget. These included: $25.9 million in additional funding for undergraduate financial aid in fiscal year 2010; $3.1 million for increased inmate medical costs; $3.0 million in additional funding for the existing pretrial services program; $5.0 million in additional funding for the Governor's Development Opportunity Fund; $10.0 million to provide funding to support agricultural best management practices; $5.8 million to the Department of Taxation to implement an enhanced compliance initiative; $2.5 million in funding for staffing new and expanded jails; and $10.8 million is additional funding for the Criminal Fund. The 2009 Budget Bill was considered by the 2009 General Assembly, which convened on January 14, 2009 and adjourned on February 28, 2009. 

The 2009 Budget Bill, as amended by the General Assembly, was submitted to the Governor for his approval and reflects the Governor's revised general fund revenue forecast by reducing revenues by an additional $821.5 million, bringing the total downward revenue revision for the biennium to $3.7 billion. The 2009 Budget Bill provides a total of $14.3 billion for direct aid to public education over the 2008-2010 biennium; includes $10.0 million for a system-wide 8.5 percent increase in student financial aid; includes $183.3 million over the introduced budget for increased enrollment in and utilization of Medicaid due to the economic downturn; adds $.5 million in fiscal year 2010 to partially restore reductions to Virginia state parks; and adds $6.6 million in fiscal year 2010 to fund aid to localities for state support for local police departments required under House Bill 599.

The Governor signed the amended bill and returned it to the General Assembly with three item vetoes for action at its one-day reconvened session held April 8, 2009. The General Assembly upheld all of the Governor's budget item vetoes. The 2009 Budget Bill became law on April 8, 2009, as Chapter 781 of the 2009 Virginia Acts of Assembly (the "2009 Appropriation Act").

Litigation. The Commonwealth, its officials and employees are named as defendants in legal proceedings which occur in the normal course of governmental operations, some involving substantial amounts. It is not possible at the present time to estimate the ultimate outcome or liability, if any, of the Commonwealth with respect to these lawsuits. However, the ultimate liability resulting from these suits is not expected to have a material, adverse effect on the financial condition of the Commonwealth.

Ratings of the Commonwealth's Securities. As of October, 2009, Standard & Poor's had rated the Commonwealth's general obligation bonds "AAA," Moody's had rated those bonds "Aaa" and Fitch had rated those bonds "AAA."

Puerto Rico. Puerto Rico has a diversified economy dominated by the manufacturing and service sectors. The Commonwealth of Puerto Rico differs from the states in its relationship with the federal government. Most federal taxes, except those such as social security taxes that are imposed by mutual consent, are not levied in Puerto Rico. During the mid and late 1990s the Commonwealth of Puerto Rico benefited from a robust U.S. economy, more aggressive tax collections and low oil prices. This created an expanded employment base, job growth, reduction in unemployment, increase in tourism spending, real GDP growth in the 3.1% to 3.5% range and significant increases in general fund cash balances from fiscal year end 1997 to fiscal year end 1999. These factors, combined with minimal negative impact from the 1996 federal legislation phasing out Section 936 tax benefits to Puerto Rico subsidiaries of U.S. Corporations, created a positive outlook for the credit in the late 1990s.

In early 2000, the outlook on the credit turned negative due to the slowdown in the U.S. economy (88% of Puerto Rico's exports go to the U.S.), uncertainty regarding increasing oil prices, failure of the government to reign in health care costs, expense overruns in education and a decreasing rate of employment growth. As a result, the general fund recorded operating deficits during fiscal years 2000-2009 while general obligation ("GO") debt increased. During that timeframe, S&P downgraded the GO credit from A- to BBB- and Moody's downgraded from Baa1 to Baa3. (Fitch does not rate the GO.) The island of Puerto Rico has been in an economic recession for three years, with its condition now exacerbated by the mainland recession. They are counting on $5.5B in federal stimulus dollars and the new governor's fiscal and economic reconstruction plans to begin to pave the way to financial stability.

The U.S. Virgin Islands. The United States Virgin Islands ("USVI") is heavily reliant on the tourism industry, with roughly 43% of non-agricultural employment in tourist-related trade and services. The tourism industry is economically sensitive and is adversely affected by the recession in the United States and Europe. An important component of the USVI revenue base is the federal excise tax on rum exports. Tax revenues rebated by the federal government to the USVI provide the primary security of many outstanding USVI bonds. Since more than 90% of the rum distilled in the USVI is distilled at one plant, any interruption in its operations (as occurred after Hurricane Hugo in 1989) would adversely affect these revenues. However, another plant is currently under construction. The last major hurricane to impact the USVI was Hurricane Marilyn on September 15, 1995. Consequently, there can be no assurance that rum exports to the United States and the rebate of tax revenues to the USVI will continue at their present levels. Moody's assigned a Baa3 rating to the territory and S&P a BBB- in September 2006.

Guam. Guam is a United States territory located 3,700 miles west of Hawaii and 1,500 miles southeast of Japan and its economy is based primarily on Japanese and Korean (86%) tourism and the United States military due to its strategic position as the westernmost territory/state in the United States. The territory boasts a population of 178,000. After almost a decade of persistent operating deficits, Guam reported operating surpluses in fiscal years 2007 and 2008 and is expected to report at least a $12MM surplus in fiscal year 2009 (9/30 year end). Prior operating deficits were caused by a number of issues including terrorist attacks, natural disasters, Asian recessions, the SARS epidemic, retiree settlement liabilities and past administrations and legislatures that were unwilling to control expenses. Clearly, any of these negative events could occur in the future and jeopardize the territory's single B+ rating from S&P. Guam appears to be surviving the current recession from a jobs perspective with 2.3% and 2.4% job growth in 2007 and 2008, respectively. Partially offsetting jobs growth is tourism which was
down 7% in 2008 and is down 9% in 2009 to date due to economic factors. However, the island still boasted 1.1 million visitors in 2008. Guam is not rated by Moody's or Fitch.

Appendix C

Municipal Bond Ratings Definitions

Below are summaries of the rating definitions used by the nationally-recognized rating agencies listed below for municipal securities. Those ratings represent the opinion of the agency as to the credit quality of issues that they rate. The summaries below are based upon publicly available information provided by the rating organizations.

Moody's Investors Service, Inc. ("Moody's")
Municipal Ratings are opinions of the investment quality of issuers and issues in the U.S. municipal and tax-exempt markets. As such, these ratings incorporate Moody's assessment of the default probability and loss severity of these issuers and issues.

Municipal Ratings are based upon the analysis of four primary factors relating to municipal finance: economy, debt, finances, and administration/management strategies. Each of the factors is evaluated individually and for its effect on the other factors in the context of the municipality's ability to repay its debt.

MUNICIPAL LONG-TERM RATING DEFINITIONS

Aaa: Issuers or issues rated "Aaa" demonstrate the strongest creditworthiness relative to other US municipal or tax-exempt issuers or issues.

Aa: Issuers or issues rated "Aa" demonstrate very strong creditworthiness relative to other US municipal or tax-exempt issuers or issues.

A: Issuers or issues rated "A" present above-average creditworthiness relative to other US municipal or tax-exempt issuers or issues.

Baa: Issuers or issues rated "Baa" represent average creditworthiness relative to other US municipal or tax- exempt issuers or issues.

Ba: Issuers or issues rated "Ba" demonstrate below-average creditworthiness relative to other US municipal or tax-exempt issuers or issues.

B: Issuers or issues rated "B" demonstrate weak creditworthiness relative to other US municipal or tax- exempt issuers or issues.

Caa: Issuers or issues rated "Caa" demonstrate very weak creditworthiness relative to other US municipal or tax-exempt issuers or issues.

Ca: Issuers or issues rated "Ca" demonstrate extremely weak creditworthiness relative to other US municipal or tax-exempt issuers or issues.

C: Issuers or issues rated "C" demonstrate the weakest creditworthiness relative to other US municipal or tax-exempt issuers or issues.

Moody's applies numerical modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid- range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

MIG/VMIG RATINGS: U.S. SHORT-TERM RATINGS
In municipal debt issuance, there are three rating categories for short-term obligations that are considered investment grade. These ratings are designated as Moody's Investment Grade (MIG) and are divided into three levels -- MIG 1 through MIG 3.
In addition, those short-term obligations that are of speculative quality are designated SG, or speculative grade.

In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned. The first element represents Moody's evaluation of the degree of risk associated with scheduled principal and interest payments. The second element represents Moody's evaluation of the degree of risk associated with the demand feature, using the MIG rating scale.

The short-term rating assigned to the demand feature of VRDOs is designated as VMIG. When either the long- or short-term aspect of a VRDO is not rated, that piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

MIG ratings expire at note maturity. By contrast, VMIG rating expirations will be a function of each issue's specific structural or credit features.

MIG 1/VMIG 1: Denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2: Denotes strong credit quality. Margins of protection are ample although not as large as in the preceding group.

MIG 3/VMIG 3: Denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well established.

SG: Denotes speculative-grade credit quality. Debt instruments in this category may lack margins of protection.

Standard & Poor's Ratings Services ("Standard & Poor's"), a division of The McGraw-Hill Companies, Inc.

LONG-TERM ISSUE CREDIT RATINGS
Issue credit ratings are based in varying degrees, on the following considerations:

• Likelihood of payment-capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

• Nature of and provisions of the obligation; and

• Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.

The issue ratings definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above.

AAA: An obligation rated ‘AAA' has the highest rating assigned by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA: An obligation rated 'AA' differs from the highest-rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A: An obligation rated 'A' is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB: An obligation rated 'BBB' exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC, CC, and C: Obligations rated 'BB', 'B', 'CCC', 'CC', and 'C' are regarded as having significant speculative characteristics. ‘BB' indicates the least degree of speculation and ‘C' the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB: An obligation rated 'BB' is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions, which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B: An obligation rated 'B' is more vulnerable to nonpayment than obligations rated 'BB', but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC: An obligation rated 'CCC' is currently vulnerable to nonpayment and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated 'CC' is currently highly vulnerable to nonpayment.

C: The 'C' rating may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on this obligation are being continued.

D: An obligation rated 'D' is in payment default. The 'D' rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor's believes that such payments will be made during such grace period. The ‘D' rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

The ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

c: The 'c' subscript is used to provide additional information to investors that the bank may terminate its obligation to purchase tendered bonds if the long-term credit rating of the issuer is below an investment-grade level and/or the issuer's bonds are deemed taxable.

p: The letter 'p' indicates that the rating is provisional. A provisional rating assumes the successful completion of the project financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful, timely completion of the project. This rating, however, while addressing credit quality subsequent to completion of the project, makes no comment on the likelihood of or the risk of default upon failure of such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

Continuance of the ratings is contingent upon Standard & Poor's receipt of an executed copy of the escrow agreement or closing documentation confirming investments and cash flows.

r: The 'r' highlights derivative, hybrid, and certain other obligations that Standard & Poor's believes may experience high volatility or high variability in expected returns as a result of noncredit risks. Examples of such obligations are securities with principal or interest return indexed to equities, commodities, or currencies; certain swaps and options; and interest-only and principal-only mortgage securities. The absence of an 'r' symbol should not be taken as an indication that an obligation will exhibit no volatility or variability in total return.

N.R. Not rated.

Debt obligations of issuers outside the United States and its territories are rated on the same basis as domestic corporate and municipal issues. The ratings measure the creditworthiness of the obligor but do not take into account currency exchange and related uncertainties.

Bond Investment Quality Standards

Under present commercial bank regulations issued by the Comptroller of the Currency, bonds rated in the top four categories ('AAA', 'AA', 'A', and 'BBB', commonly known as investment-grade ratings) generally are regarded as eligible for bank investment. Also, the laws of various states governing legal investments impose certain rating or other standards for obligations eligible for investment by savings banks, trust companies, insurance companies, and fiduciaries in general.

SHORT-TERM ISSUE CREDIT RATINGS
Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days-including commercial paper.

A-1: A short-term obligation rated "A-1" is rated in the highest category by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated "A-2" is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated "A-3" exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

B: A short-term obligation rated "B" is regarded as having significant speculative characteristics. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

C: A short-term obligation rated "C" is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated "D" is in payment default. The "D" rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor's believes that such payments will be made during such grace period. The "D" rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Notes. A Standard & Poor's note rating reflects the liquidity factors and market access risks unique to notes. Notes due in three years or less will likely receive a note rating. Notes maturing beyond three years will most likely receive a long-term debt rating. The following criteria will be used in making that assessment:

• Amortization schedule-the larger the final maturity relative to other maturities, the more likely it will
  be treated as a note; and

• Source of payment-the more dependent the issue is on the market for its refinancing, the more likely
  it will be treated as a note.

SP-1: Strong capacity to pay principal and interest. An issue with a very strong capacity to pay debt service is given a (+) designation.

SP-2: Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3: Speculative capacity to pay principal and interest.

Fitch, Inc.
International credit ratings assess the capacity to meet foreign currency or local currency commitments. Both "foreign currency" and "local currency" ratings are internationally comparable assessments. The local currency rating measures the probability of payment within the relevant sovereign state's currency and jurisdiction and therefore, unlike the foreign currency rating, does not take account of the possibility of foreign exchange controls limiting transfer into foreign currency.

INTERNATIONAL LONG-TERM CREDIT RATINGS
The following ratings scale applies to foreign currency and local currency ratings.
Investment Grade:

AAA: Highest Credit Quality. "AAA" ratings denote the lowest expectation of credit risk. They are assigned only in the case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very High Credit Quality. "AA" ratings denote a very low expectation of credit risk. They indicate a very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High Credit Quality. "A" ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB: Good Credit Quality. "BBB" ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Speculative Grade:

BB: Speculative. "BB" ratings indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time. However, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment grade.

B: Highly Speculative. "B" ratings indicate that significant credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met. However, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

CCC, CC, and C: High Default Risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments. A "CC" rating indicates that default of some kind appears probable. "C" ratings signal imminent default.

DDD, DD, and D: Default. The ratings of obligations in this category are based on their prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. "DDD" obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest. "DD" indicates potential recoveries in the range of 50%-90%, and "D" the lowest recovery potential, i.e., below 50%.

Entities rated in this category have defaulted on some or all of their obligations. Entities rated "DDD" have the highest prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated "DD" and "D" are generally undergoing a formal reorganization or liquidation process; those rated "DD" are likely to satisfy a higher portion of their outstanding obligations, while entities rated "D" have a poor prospect for repaying all obligations.
Plus (+) and minus (-) signs may be appended to a rating symbol to denote relative status within the major rating categories. Plus and minus signs are not added to the "AAA" category or to categories below "CCC," nor to short-term ratings other than "F1" (see below).

INTERNATIONAL SHORT-TERM CREDIT RATINGS
The following ratings scale applies to foreign currency and local currency ratings. A short-term rating has a time horizon of less than 12 months for most obligations, or up to three years for U.S. public finance securities, and thus places greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

F1: Highest credit quality. Strongest capacity for timely payment of financial commitments. May have an added "+" to denote any exceptionally strong credit feature.

F2: Good credit quality. A satisfactory capacity for timely payment of financial commitments, but the margin of safety is not as great as in the case of higher ratings.

F3: Fair credit quality. Capacity for timely payment of financial commitments is adequate. However, near-term adverse changes could result in a reduction to non-investment grade.

B: Speculative. Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

C: High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon a sustained, favorable business and economic environment.

D: Default. Denotes actual or imminent payment default.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1)	Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)
2)	Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)
3)	Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

	Level 1—		Level 2—		Level 3—
	Unadjusted		Other Significant		Significant
	Quoted Prices		Observable Inputs		Unobservable Inputs		Value

OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Arizona 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Arizona state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign

OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

security traded on a foreign exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Securities on a When-Issued or Delayed Delivery Basis. The Fund may purchase securities on a “when-issued” basis, and may purchase or sell securities on a “delayed delivery” basis. “When-issued” or “delayed delivery” refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis normally takes place within six months and possibly as long as two years or more after the trade date. During this period, such securities do not earn interest, are subject to market fluctuation and may increase or decrease in value prior to their delivery.

OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

The purchase of securities on a when-issued basis may increase the volatility of the Fund’s net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. When the Fund engages in when-issued or delayed delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain or dispose of the security at a price and yield it considers advantageous. The Fund may also sell securities that it purchased on a when-issued basis or forward commitment prior to settlement of the original purchase.

As of March 31, 2010, the Fund had purchased securities issued on a when-issued or delayed delivery basis and sold securities issued on a delayed delivery basis as follows:

	When-Issued or Delayed
	Delivery Basis Transactions
Purchased securities	$	1,114,045

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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.  As of March 31, 2010, the Fund had $4,888,915 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

Expiring
2016	$	154,655
2017		1,909,891
2018		2,824,369
Total	$	4,888,915

2.  As of March 31, 2010, the Fund had $31,235 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.

3.  During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.

4.  During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

Accordingly, the following amounts have been reclassified for March 31, 2010. Net assets of the Fund were unaffected by the reclassifications.

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

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 March 31, 2010 are noted in the following table. 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.

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	203
Payments Made to Retired Trustees		130
Accumulated Liability as of March 31, 2010		1,088

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

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

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $15,341 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

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

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine

The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	44,880
Class C		94,857

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

			Class A		Class B		Class C

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $81,845, $3,845 and $24,207 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing

OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.41% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	4,455,890
Average Daily Interest Rate		0.438	%
Fees Paid	$	118,349
Interest Paid	$	20,223

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and

OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

7. Pending Litigation Continued

distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff “). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
Oppenheimer Rochester Massachusetts Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Massachusetts Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period July 18, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Massachusetts Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period July 18, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

STATEMENT OF INVESTMENTS Continued

Footnotes to Statement of Investments

1.	All or a portion of the security position has been segregated for collateral to cover borrowings. See Note 5 of accompanying Notes.
2.	Security represents the underlying municipal bond on an inverse floating rate security. The bond was purchased by the Fund and subsequently segregated and transferred to a trust. See Note 1 of accompanying Notes.
3.	Zero coupon bond reflects effective yield on the date of purchase.
4.	When-issued security or delayed delivery to be delivered and settled after March 31, 2010. See Note 1 of accompanying Notes.
5.	Denotes a step bond: a zero coupon bond that converts to a fixed or variable interest rate at a designated future date.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1)	Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)
2)	Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)
3)	Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3—
	Level 1—		Level 2—		Significant
	Unadjusted		Other Significant		Unobservable

6.	Total expenses ratio is higher due to the Fund’s limited operating history.
7.	Prior to July 1, 2009, the Manager voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses,” excluding expenses attributable to investments in inverse floaters, as a percentage of average daily net assets would not exceed 0.80%. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings.

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Massachusetts 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Massachusetts state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Securities on a When-Issued or Delayed Delivery Basis. The Fund may purchase securities on a “when-issued” basis, and may purchase or sell securities on a “delayed delivery” basis. “When-issued” or “delayed delivery” refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis normally takes place within six months and possibly as long as two

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

years or more after the trade date. During this period, such securities do not earn interest, are subject to market fluctuation and may increase or decrease in value prior to their delivery. The purchase of securities on a when-issued basis may increase the volatility of the Fund’s net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. When the Fund engages in when-issued or delayed delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain or dispose of the security at a price and yield it considers advantageous. The Fund may also sell securities that it purchased on a when-issued basis or forward commitment prior to settlement of the original purchase.

As of March 31, 2010, the Fund had purchased securities issued on a when-issued or delayed delivery basis and sold securities issued on a delayed delivery basis as follows:

	When-Issued or Delayed
	Delivery Basis Transactions
Purchased securities	$	557,023

Inverse Floating Rate Securities. The Fund invests in inverse floating rate securities that pay interest at a rate that varies inversely with short-term interest rates. Certain of these securities may be leveraged, whereby the interest rate varies inversely at a multiple of the change in short-term rates. As interest rates rise, inverse floaters produce less current income. The price of such securities is more volatile than comparable fixed rate securities. The Fund may expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters. The Fund’s exposure to the effects of leverage from its investments in inverse floaters amount to $4,390,000 as of March 31, 2010, which represents 5.73% 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

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

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 March 31, 2010, municipal bond holdings with a value of $5,805,272 shown on the Fund’s Statement of Investments are held by such Trusts and serve as collateral for the $4,390,000 in short-term floating rate notes issued and outstanding at that date.

     The Fund’s investments in inverse floaters involve certain risks. The market value of an inverse floating rate security can be more volatile than that of a conventional fixed-rate bond having similar credit quality, maturity and redemption provisions. Typically, an inverse floating rate security tends to underperform fixed rate bonds when long-term interest rates are rising but tends to outperform fixed rate bonds when long-term interest rates are stable or falling. An inverse floating rate security entails a degree of leverage because the trust issues short-term securities in a ratio to the inverse floating rate security with the underlying long-term bond providing collateral for the obligation to pay the principal value of the short-term securities if and when they are tendered. If the Fund has created the inverse floater by depositing a long-term bond into a trust, it may be required to provide additional collateral for the short-term securities if the value of the underlying bond deposited in the trust falls.

At March 31, 2010, the Fund’s residual exposure to these types of inverse floating rate securities were as follows:

Principal			Coupon			Maturity
Amount		Inverse Floater1	Rate2			Date		Value
$	1,310,000	MA Educational Financing
		Authority ROLs3		25.140	%		1/1/30	$	1,415,272

1.	For a list of abbreviations used in the Inverse Floater table see the Portfolio Abbreviations table on page F6 of the Statement of Investments.
2.	Represents the current interest rate for a variable rate bond known as an “inverse floater.”
3.	Security is subject to a shortfall and forbearance agreement.

The Fund enters into shortfall and forbearance agreements with the sponsors of certain inverse floaters held by the Fund. These agreements commit the Fund to reimburse the sponsor of the inverse floater, in certain circumstances, for the amount of the difference between the liquidation value of the underlying security (which is the basis of the inverse floater) and the principal amount due to the holders of the short-term floating rate notes issued by the Trust in conjunction with the inverse floating rate security. Under the 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 March 31, 2010, in addition to the

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

exposure detailed in the preceding table, the Fund’s maximum exposure under such agreements is estimated at $4,390,000.

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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. As of March 31, 2010, the Fund had $5,643,700 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

Expiring

2.	As of March 31, 2010, the Fund had $544,883 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.
3.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
4.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

Accordingly, the following amounts have been reclassified for March 31, 2010. Net assets of the Fund were unaffected by the reclassifications.

	Increase to
Reduction to	Accumulated Net
Paid-in Capital	Investment Income
$152	$	152

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

	Year Ended		Year Ended
	March 31, 2010		March 31, 2009

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 March 31, 2010 are noted in the following table. 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	$	74,471,694	5
Gross unrealized appreciation	$	1,807,657
Gross unrealized depreciation		(6,511,997	)
Net unrealized depreciation	$	(4,704,340	)

5. The Federal tax cost of securities does not include cost of $4,407,712, which has otherwise been recognized for financial reporting purposes, related to bonds placed into trusts in conjunction with certain investment transactions. See the Inverse Floating Rate Securities note above.

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

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

their benefits under the Plan. During the year ended March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	302
Payments Made to Retired Trustees		177
Accumulated Liability as of March 31, 2010		1,490

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

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

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

may also enter into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Other. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $28,331 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

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

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	36,955
Class C		276,908

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

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $83,476, $6,685 and $40,219 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

OPPENHEIMER ROCHESTER MASSACHUSETTS MUNICIPAL FUND

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.17% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	2,711,781
Average Daily Interest Rate		0.438	%
Fees Paid	$	92,896
Interest Paid	$	12,763

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

7. Pending Litigation Continued

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff ”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of Oppenheimer Rochester Maryland Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Maryland Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period October 10, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Maryland Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period October 10, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1)	Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)
2)	Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)
3)	Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3—
	Level 1—		Level 2—		Significant
	Unadjusted		Other Significant		Unobservable

Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Maryland 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Maryland state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal

OPPENHEIMER ROCHESTER MARYLAND MUNICIPAL FUND

exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Inverse Floating Rate Securities. The Fund invests in inverse floating rate securities that pay interest at a rate that varies inversely with short-term interest rates. Certain of these securities may be leveraged, whereby the interest rate varies inversely at a multiple of the change in short-term rates. As interest rates rise, inverse floaters produce less current income. The price of such securities is more volatile than comparable fixed rate securities. The Fund may expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters. The Fund’s exposure to the effects of leverage from its

OPPENHEIMER ROCHESTER MARYLAND MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

investments in inverse floaters amount to $6,000,000 as of March 31, 2010, which represents 6.85% 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 March 31, 2010, municipal bond holdings with a value of $8,435,840 shown on the Fund’s Statement of Investments are held by such Trusts and serve as collateral for the $6,000,000 in short-term floating rate notes issued and outstanding at that date.

     The Fund’s investments in inverse floaters involve certain risks. The market value of an inverse floating rate security can be more volatile than that of a conventional fixed-rate bond having similar credit quality, maturity and redemption provisions. Typically, an inverse floating rate security tends to underperform fixed rate bonds when long-term interest rates are rising but tends to outperform fixed rate bonds when long-term interest rates are stable or falling. An inverse floating rate security entails a degree of leverage because the trust issues short-term securities in a ratio to the inverse floating rate security with the underlying long-term bond providing collateral for the obligation to pay the principal value of the short-term securities if and when they are tendered. If the Fund has created the inverse floater by depositing a long-term bond into a trust, it may be required to provide additional collateral for the short-term securities if the value of the underlying bond deposited in the trust falls.

OPPENHEIMER ROCHESTER MARYLAND MUNICIPAL FUND

At March 31, 2010, the Fund’s residual exposure to these types of inverse floating rate securities were as follows:

Principal			Coupon			Maturity
Amount		Inverse Floater1	Rate2			Date		Value
$	2,000,000	Puerto Rico Sales Tax Financing Corp. ROLs3		20.519	%		8/1/57	$	2,435,840

1.	For a list of abbreviations used in the Inverse Floater table see the Portfolio Abbreviations table on page F7 of the Statement of Investments.
2.	Represents the current interest rate for a variable rate bond known as an “inverse floater.”
3.	Security is subject to a shortfall and forbearance agreement.

The Fund enters into shortfall and forbearance agreements with the sponsors of certain inverse floaters held by the Fund. These agreements commit the Fund to reimburse the sponsor of the inverse floater, in certain circumstances, for the amount of the difference between the liquidation value of the underlying security (which is the basis of the inverse floater) and the principal amount due to the holders of the short-term floating rate notes issued by the Trust in conjunction with the inverse floating rate security. Under the 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 March 31, 2010, in addition to the exposure detailed in the preceding table, the Fund’s maximum exposure under such agreements is estimated at $6,000,000.

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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.

2.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
3.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

	Year Ended		Year Ended
	March 31, 2010		March 31, 2009

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 March 31, 2010 are noted in the following table. 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.

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	350
Payments Made to Retired Trustees		174
Accumulated Liability as of March 31, 2010		1,480

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

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

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $30,992 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

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

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of

Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $87,483, $6,737 and $67,434 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to

OPPENHEIMER ROCHESTER MARYLAND MUNICIPAL FUND

such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.28% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	4,988,767
Average Daily Interest Rate		0.438	%
Fees Paid	$	165,166
Interest Paid	$	25,266

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming

NOTES TO FINANCIAL STATEMENTS Continued

7. Pending Litigation Continued

the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
Oppenheimer Rochester Michigan Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Michigan Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period June 21, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Michigan Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period June 21, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1) Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)

2) Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)

3) Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3 –
	Level 1 –		Level 2 –		Significant
	Unadjusted		Other Significant		Unobservable

The investment objective of the Fund is to seek a high level of current interest income exempt from federal and Michigan state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal

exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Credit Risk. The Fund invests in high-yield, non-investment-grade bonds, which may be subject to a greater degree of credit risk. Credit risk relates to the ability of the issuer to meet interest or principal payments or both as they become due. The Fund may acquire securities in default, and is not obligated to dispose of securities whose issuers subsequently default. Information concerning securities in default as of March 31, 2010 is as follows:

Cost	$	79,812
Market Value	$	25,565
Market Value as a % of Net Assets		0.06	%

OPPENHEIMER ROCHESTER MICHIGAN MUNICIPAL FUND

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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. As of March 31, 2010, the Fund had $10,700,676 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

2.	As of March 31, 2010, the Fund had $499,074 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.
3.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
4.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

	Year Ended		Year Ended
	March 31, 2010		March 31, 2009
Distributions paid from:
Exempt-interest dividends	$	2,939,083	$	2,843,515
Ordinary income		728		8,296
Total	$	2,939,811	$	2,851,811

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 March 31, 2010 are noted in the following table. 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	$	53,061,273
Gross unrealized appreciation	$	1,707,006
Gross unrealized depreciation		(9,443,760	)
Net unrealized depreciation	$	(7,736,754	)

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	249
Payments Made to Retired Trustees		200
Accumulated Liability as of March 31, 2010		1,660

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

OPPENHEIMER ROCHESTER MICHIGAN MUNICIPAL FUND

owed to the Trustee under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or in other Oppenheimer funds selected by the Trustee. The Fund purchases shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Fund asset equal to the deferred compensation liability. Such assets are included as a component of “Other” within the asset section of the Statement of Assets and Liabilities. Deferral of trustees’fees under the plan will not affect the net assets of the Fund, and will not materially affect the Fund’s assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the compensation deferral plan.

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

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and

the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

	Purchases		Sales
Investment securities	$	17,917,841	$	10,563,031

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

OPPENHEIMER ROCHESTER MICHIGAN MUNICIPAL FUND

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 year ended March 31, 2010, the Fund paid $21,778 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

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

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	85,127
Class C		184,235

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

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $62,956, $6,572 and $32,472 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders and a bank which enables it to participate with certain other Oppenheimer funds in a committed, secured borrowing facility that permits borrowings

OPPENHEIMER ROCHESTER MICHIGAN MUNICIPAL FUND

of up to $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.28% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	3,439,726
Average Daily Interest Rate		0.438	%
Fees Paid	$	91,414
Interest Paid	$	14,027

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege

OPPENHEIMER ROCHESTER MICHIGAN MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

7. Pending Litigation Continued

breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff “). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of

Oppenheimer Rochester Minnesota Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Minnesota Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period November 7, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Minnesota Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period November 7, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

2.	Represents the current interest rate for a variable or increasing rate security.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1)	Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)
2)	Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)
3)	Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3—
	Level 1—		Level 2—		Significant
	Unadjusted		Other Significant		Unobservable

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Minnesota 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Minnesota state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

security traded on a foreign exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

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

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. As of March 31, 2010, the Fund had $2,219,960 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

Expiring
2016	$	91,561
2017		190,675
2018		1,937,724
Total	$	2,219,960

2.	As of March 31, 2010, the Fund had $8,175 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.
3.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
4.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

	Year Ended		Year Ended
	March 31, 2010		March 31, 2009
Distributions paid from:
Exempt-interest dividends	$	2,037,931	$	1,598,807
Ordinary income		2,139		990
Total	$	2,040,070	$	1,599,797

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 March 31, 2010 are noted in the following table. 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	$	44,578,632
Gross unrealized appreciation	$	2,169,204
Gross unrealized depreciation		(2,377,165	)
Net unrealized depreciation	$	(207,961	)

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	202
Payments Made to Retired Trustees		98
Accumulated Liability as of March 31, 2010		837

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

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

plan will not affect the net assets of the Fund, and will not materially affect the Fund’s assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the compensation deferral plan.

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

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	36,924
Class C		95,447

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

Year Ended	Distributor		Distributor		Distributor		Distributor
March 31, 2010	$	79,351	$	—	$	4,297	$	2,900

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $90,785, $4,379 and $16,098 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest

5. Borrowings Continued

is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.29% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	3,156,712
Average Daily Interest Rate		0.438	%
Fees Paid	$	95,349
Interest Paid	$	14,085

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/ or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

OPPENHEIMER ROCHESTER MINNESOTA MUNICIPAL FUND

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
Oppenheimer Rochester North Carolina Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester North Carolina Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period October 10, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester North Carolina Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period October 10, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

STATEMENT OF INVESTMENTS Continued

Footnotes to Statement of Investments

1.	All or a portion of the security position has been segregated for collateral to cover borrowings. See Note 5 of accompanying Notes.
2.	Security represents the underlying municipal bond on an inverse floating rate security. The bond was purchased by the Fund and subsequently segregated and transferred to a trust. See Note 1 of accompanying Notes.
3.	Zero coupon bond reflects effective yield on the date of purchase.
4.	Denotes a step bond: a zero coupon bond that converts to a fixed or variable interest rate at a designated future date.
5.	Represents the current interest rate for a variable or increasing rate security.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1) Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)

2) Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)

3) Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3—
	Level 1—		Level 2—		Significant
	Unadjusted		Other Significant		Unobservable
	Quoted Prices		Observable Inputs		Inputs		Value

Futures, if any, are reported at their variation margin at measurement date, which represents the amount due to/from the Fund at that date. All additional assets and liabilities included in the above table are reported at their market value at measurement date.

OPPENHEIMER ROCHESTER NORTH CAROLINA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester North Carolina 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and North Carolina state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current

OPPENHEIMER ROCHESTER NORTH CAROLINA MUNICIPAL FUND

1. Significant Accounting Policies Continued

day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

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.

OPPENHEIMER ROCHESTER NORTH CAROLINA MUNICIPAL FUND

The Fund may expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters. The Fund’s exposure to the effects of leverage from its investments in inverse floaters amount to $12,000,000 as of March 31, 2010, which represents 12.51% 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 March 31, 2010, municipal bond holdings with a value of $16,455,240 shown on the Fund’s Statement of Investments are held by such Trusts and serve as collateral for the $12,000,000 in short-term floating rate notes issued and outstanding at that date.

     The Fund’s investments in inverse floaters involve certain risks. The market value of an inverse floating rate security can be more volatile than that of a conventional fixed-rate bond having similar credit quality, maturity and redemption provisions. Typically, an inverse floating rate security tends to underperform fixed rate bonds when long-term interest rates are rising but tends to outperform fixed rate bonds when long-term interest rates are stable or falling. An inverse floating rate security entails a degree of leverage because the trust issues short-term securities in a ratio to the inverse floating rate security with the underlying long-term bond providing collateral for the obligation to pay the principal value of the short-term securities if and when they are tendered. If the Fund has created the inverse floater by depositing a long-term bond into a trust, it may be required to provide additional collateral for the short-term securities if the value of the underlying bond deposited in the trust falls.

1. Significant Accounting Policies Continued

At March 31, 2010, the Fund’s residual exposure to these types of inverse floating rate securities were as follows:

Principal			Coupon			Maturity
Amount		Inverse Floater1	Rate2			Date		Value
$	2,000,000	NC Medical Care Commission ROLs3		17.688	%		6/1/42	$	2,019,400

1.	For a list of abbreviations used in the Inverse Floater table see the Portfolio Abbreviations table on page F6 of the Statement of Investments.
2.	Represents the current interest rate for a variable rate bond known as an “inverse floater.”
3.	Security is subject to a shortfall and forbearance agreement.

The Fund enters into shortfall and forbearance agreements with the sponsors of certain inverse floaters held by the Fund. These agreements commit the Fund to reimburse the sponsor of the inverse floater, in certain circumstances, for the amount of the difference between the liquidation value of the underlying security (which is the basis of the inverse floater) and the principal amount due to the holders of the short-term floating rate notes issued by the Trust in conjunction with the inverse floating rate security. Under the 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 March 31, 2010, in addition to the exposure detailed in the preceding table, the Fund’s maximum exposure under such agreements is estimated at $12,000,000.

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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

1. As of March 31, 2010, the Fund had $7,131,870 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

2.	As of March 31, 2010, the Fund had $15,799 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.
3.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
4.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

Accordingly, the following amounts have been reclassified for March 31, 2010. Net assets of the Fund were unaffected by the reclassifications.

5. The Federal tax cost of securities does not include cost of $11,994,155, which has otherwise been recognized for financial reporting purposes, related to bonds placed into trusts in conjunction with certain investment transactions. See the Inverse Floating Rate Securities note above.

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	389
Payments Made to Retired Trustees		209
Accumulated Liability as of March 31, 2010		1,769

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

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

OPPENHEIMER ROCHESTER NORTH CAROLINA MUNICIPAL FUND

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $39,427 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

Service Plan for Class A Shares. The Fund has adopted a Service Plan (the “Plan”) for Class A shares under Rule 12b-1 of the Investment Company Act of 1940. Under the Plan, the Fund reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made periodically at

OPPENHEIMER ROCHESTER NORTH CAROLINA MUNICIPAL FUND

an annual rate of up to 0.25% of the daily net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions periodically for providing personal service and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent periods. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations.

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	74,036
Class C		313,532

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

			Class A		Class B		Class C

Year Ended	Distributor		Distributor		Distributor		Distributor
March 31, 2010	$	86,017	$	—	$	3,100	$	2,699

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $108,892, $6,186 and $49,271 for Class A, Class B and Class C shares, respectively.

NOTES TO FINANCIAL STATEMENTS Continued

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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.19% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	3,342,466
Average Daily Interest Rate		0.457	%
Fees Paid	$	137,981
Interest Paid	$	21,369

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of Oppenheimer Rochester Ohio Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Ohio Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period June 21, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Ohio Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period June 21, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1)	Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)
2)	Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)
3)	Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Ohio 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Ohio state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

1. Significant Accounting Policies Continued

the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

Securities on a When-Issued or Delayed Delivery Basis. The Fund may purchase securities on a “when-issued” basis, and may purchase or sell securities on a “delayed delivery” basis. “When-issued” or “delayed delivery” refers to securities whose terms and indenture are available and for which a market exists, but which are not available

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

for immediate delivery. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis normally takes place within six months and possibly as long as two years or more after the trade date. During this period, such securities do not earn interest, are subject to market fluctuation and may increase or decrease in value prior to their delivery. The purchase of securities on a when-issued basis may increase the volatility of the Fund’s net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. When the Fund engages in when-issued or delayed delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain or dispose of the security at a price and yield it considers advantageous. The Fund may also sell securities that it purchased on a when-issued basis or forward commitment prior to settlement of the original purchase.

As of March 31, 2010, the Fund had purchased securities issued on a when-issued or delayed delivery basis and sold securities issued on a delayed delivery basis as follows:

	When-Issued or Delayed
	Delivery Basis Transactions
Purchased securities	$	557,023

Credit Risk. The Fund invests in high-yield, non-investment-grade bonds, which may be subject to a greater degree of credit risk. Credit risk relates to the ability of the issuer to meet interest or principal payments or both as they become due. The Fund may acquire securities in default, and is not obligated to dispose of securities whose issuers subsequently default. Information concerning securities in default as of March 31, 2010 is as follows:

Cost	$	971,844
Market Value	$	—
Market Value as a % of Net Assets		—	%

Concentration Risk. There are certain risks arising from geographic concentration in any state, commonwealth or territory. Certain economic, regulatory or political developments occurring in the state, commonwealth or territory 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 Fund files income tax returns in U.S. federal and

applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

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. As of March 31, 2010, the Fund had $12,406,165 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

Expiring
2015	$	5
2016		809,696
2017		2,144,196
2018		9,452,268
Total	$	12,406,165

2.	As of March 31, 2010, the Fund had $30,495 of post-October losses available to offset future realized capital gains, if any. Such losses, if unutilized, will expire in 2019.
3.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
4.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

	Year Ended		Year Ended
	March 31, 2010		March 31, 2009
Distributions paid from:
Exempt-interest dividends	$	4,085,822	$	3,956,990
Ordinary income		194		2,228
Total	$	4,086,016	$	3,959,218

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

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 March 31, 2010 are noted in the following table. 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	$	86,514,511
Gross unrealized appreciation	$	2,259,357
Gross unrealized depreciation		(10,259,976	)
Net unrealized depreciation	$	(8,000,619	)

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	394
Payments Made to Retired Trustees		250
Accumulated Liability as of March 31, 2010		2,099

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

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

1. Significant Accounting Policies Continued

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

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $40,533 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

Service Plan for Class A Shares. The Fund has adopted a Service Plan (the “Plan”) for Class A shares under Rule 12b-1 of the Investment Company Act of 1940. Under the Plan, the Fund reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made periodically at an annual rate of up to 0.25% of the daily net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks

and other financial institutions periodically for providing personal service and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent periods. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations.

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	56,945
Class C		273,566

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

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

Manager amended this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $126,659, $11,870 and $68,275 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.48% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

5. Borrowings Continued

As of March 31, 2010, the Fund had borrowings outstanding at an interest rate of 0.2282%. Details of the borrowings for the year ended March 31, 2010 are as follows:

Average Daily Loan Balance	$	8,326,849
Average Daily Interest Rate		0.438	%
Fees Paid	$	233,378
Interest Paid	$	41,423

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent

OPPENHEIMER ROCHESTER OHIO MUNICIPAL FUND

Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
Oppenheimer Rochester Virginia Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Virginia Municipal Fund, including the statement of investments, as of March 31, 2010, 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 three-year period then ended and for the period July 18, 2006 (commencement of operations) to March 31, 2007. 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 March 31, 2010, 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 Rochester Virginia Municipal Fund as of March 31, 2010, the results of its operations and 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 three-year period then ended and for the period July 18, 2006 (commencement of operations) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

Valuation Inputs

Various data inputs are used in determining the value of each of the Fund’s investments as of the reporting period end. These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

1) Level 1—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)

2) Level 2—inputs other than unadjusted quoted prices that are observable for the asset (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)

3) Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset).

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of March 31, 2010 based on valuation input level:

					Level 3–
	Level 1–		Level 2–		Significant
	Unadjusted		Other Significant		Unobservable

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Oppenheimer Rochester Virginia 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 investment objective of the Fund is to seek a high level of current interest income exempt from federal and Virginia state income taxes for individual investors as is consistent with preservation of capital. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”).

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

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” inputs other than unadjusted quoted prices for an asset that are observable are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ^® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A foreign security traded on a foreign exchange is valued based on the last sale price on the principal

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

1. Significant Accounting Policies Continued

exchange on which the security is traded, as identified by the portfolio pricing service used by the Manager, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the most recent official closing price on the principal exchange on which it is traded.

     Shares of a registered investment company that are not traded on an exchange are valued at that investment company’s net asset value per share.

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a readily available unadjusted quoted market price, including for 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 the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

     There have been no significant changes to the fair valuation methodologies of the Fund during the period.

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

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

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

income. The price of such securities is more volatile than comparable fixed rate securities. The Fund may expose up to 20% of its total assets to the effects of leverage from its investments in inverse floaters. The Fund’s exposure to the effects of leverage from its investments in inverse floaters amount to $12,000,000 as of March 31, 2010, which represents 11.14% 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 March 31, 2010, municipal bond holdings with a value of $16,277,840 shown on the Fund’s Statement of Investments are held by such Trusts and serve as collateral for the $12,000,000 in short-term floating rate notes issued and outstanding at that date.

     The Fund’s investments in inverse floaters involve certain risks. The market value of an inverse floating rate security can be more volatile than that of a conventional fixed-rate bond having similar credit quality, maturity and redemption provisions. Typically, an inverse floating rate security tends to underperform fixed rate bonds when long-term interest rates are rising but tends to outperform fixed rate bonds when long-term interest rates are stable or falling. An inverse floating rate security entails a degree of leverage because the trust issues short-term securities in a ratio to the inverse floating rate security with the underlying long-term bond providing collateral for the obligation to pay the principal value of the short-term securities if and when they are tendered. If the Fund has created the inverse floater by depositing a long-term bond into a trust, it may be required to provide additional collateral for the short-term securities if the value of the underlying bond deposited in the trust falls.

1. Significant Accounting Policies Continued

At March 31, 2010, the Fund’s residual exposure to these types of inverse floating rate securities were as follows:

Principal
Amount	Inverse Floater1	Coupon Rate2			Maturity Date		Value
$2,000,000	Metropolitan Washington,

1.	For a list of abbreviations used in the Inverse Floater table see the Portfolio Abbreviations table on page F6 of the Statement of Investments.
2.	Represents the current interest rate for a variable rate bond known as an “inverse floater.”
3.	Security is subject to a shortfall and forbearance agreement.

The Fund enters into shortfall and forbearance agreements with the sponsors of certain inverse floaters held by the Fund. These agreements commit the Fund to reimburse the sponsor of the inverse floater, in certain circumstances, for the amount of the difference between the liquidation value of the underlying security (which is the basis of the inverse floater) and the principal amount due to the holders of the short-term floating rate notes issued by the Trust in conjunction with the inverse floating rate security. Under the 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 March 31, 2010, in addition to the exposure detailed in the preceding table, the Fund’s maximum exposure under such agreements is estimated at $12,000,000.

Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

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

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. As of March 31, 2010, the Fund had $4,179,896 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of March 31, 2010, details of the capital loss carryforwards were as follows:

2.	During the fiscal year ended March 31, 2010, the Fund did not utilize any capital loss carryforward.
3.	During the fiscal year ended March 31, 2009, the Fund did not utilize any capital loss carryforward.

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.

Accordingly, the following amounts have been reclassified for March 31, 2010. Net assets of the Fund were unaffected by the reclassifications.

The tax character of distributions paid during the years ended March 31, 2010 and March 31, 2009 was as follows:

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 March 31, 2010 are noted in the following table. The primary difference between book and tax appreciation or depreciation of securities and other investments,

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

if applicable, is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss.

Gross unrealized appreciation	$	5,601,748
Gross unrealized depreciation		(5,768,655	)
Net unrealized depreciation	$	(166,907	)

4. The Federal tax cost of securities does not include cost of $12,001,740, which has otherwise been recognized for financial reporting purposes, related to bonds placed into trusts in conjunction with certain investment transactions. See the Inverse Floating Rate Securities note above.

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 March 31, 2010, the Fund’s projected benefit obligations, payments to retired trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	242
Payments Made to Retired Trustees		120
Accumulated Liability as of March 31, 2010		1,030

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

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

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

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

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 overdraft at a rate equal to the 1 Month LIBOR Rate plus 2.00%. 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 accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

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:

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.55	%
Next $500 million	0.50
Next $500 million	0.45
Over $1.5 billion	0.40

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 year ended March 31, 2010, the Fund paid $32,779 to OFS for services to the Fund.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

Service Plan for Class A Shares. The Fund has adopted a Service Plan (the “Plan”) for Class A shares under Rule 12b-1 of the Investment Company Act of 1940. Under the Plan, the Fund reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made periodically at an annual rate of up to 0.25% of the daily net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions periodically for providing personal service and maintenance of

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent periods. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations.

Distribution and Service Plans for Class B and Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B and Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares daily net assets. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B or Class C plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at March 31, 2010 were as follows:

Class B	$	234,703
Class C		234,864

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

Waivers and Reimbursements of Expenses. Prior to July 1, 2009, the Manager had voluntarily agreed to waive management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” excluding expenses attributable to the Fund’s investments in inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares and 1.55% of average annual net assets for both Class B and Class C shares. Effective July 1, 2009, the Manager amended

OPPENHEIMER ROCHESTER VIRGINIA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

4. Fees and Other Transactions with Affiliates Continued

this voluntary undertaking so that this waiver would also exclude interest and fees from borrowings. During the year ended March 31, 2010, the Manager reimbursed $92,605, $13,127 and $33,234 for Class A, Class B and Class C shares, respectively.

     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.

     Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

5. 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. The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund can also borrow for other purposes, such as to raise money to unwind or “collapse” trusts that issued “inverse floaters” to the Fund, or to contribute to such trusts to enable them to meet tenders of their short-term securities by the holders of those securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. The purchase of securities with borrowed funds creates leverage in the Fund. The use of leverage will subject the Fund to greater costs than funds that do not borrow for leverage, and may also make the Fund’s share price more sensitive to interest changes. The interest on borrowed money is an expense that might reduce the Fund’s yield. Expenses incurred by the Fund with respect to interest on borrowings and commitment fees are disclosed separately or as other expenses on the Statement of Operations.

     The Fund entered into a Revolving Credit and Security Agreement (the “Agreement”) with conduit lenders 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 $2.25 billion, collectively. To secure the loan, the Fund pledges investment securities in accordance with the terms of the Agreement. Securities held in collateralized accounts to cover these borrowings are noted in the Statement of Investments. Interest is charged to the Fund, based on its borrowings, at current commercial paper issuance rates (0.2282% as of March 31, 2010). The Fund pays additional fees annually to its lender on its outstanding borrowings to manage and administer the facility. The Fund is also allocated its pro-rata share of an annual structuring fee and ongoing commitment fees both of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the borrowing facility during the year ended March 31, 2010 equal 0.14% of the Fund’s average net assets on an annualized basis. The Fund has the right to prepay such loans and terminate its participation in the conduit loan facility at any time upon prior notice.

6. Subsequent Events Evaluation

The Fund has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation determined that there are no subsequent events that necessitated disclosures and/ or adjustments.

7. Pending Litigation

Since 2009, a number of lawsuits have been filed in federal courts against the Manager, the Distributor, and certain mutual funds (“Defendant Funds”) advised by the Manager and distributed by the Distributor (but not including the Fund). The lawsuits naming the Defendant Funds also name as defendants certain officers, trustees and former trustees of the respective Defendant Funds. The plaintiffs seek class action status on behalf of purchasers of shares of the respective Defendant Fund during a particular time period. The lawsuits raise claims under federal securities laws alleging that, among other things, the disclosure documents of the respective Defendant Fund contained misrepresentations and omissions, that such Defendant Fund’s investment policies were not followed, and that such Defendant Fund and the other defendants violated federal securities laws and regulations. The plaintiffs seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     In 2009, lawsuits were filed in state court against the Manager and a subsidiary (but not against the Fund), on behalf of the New Mexico Education Plan Trust. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses.

     Other lawsuits have been filed since 2008 in various state and federal courts, against the Manager and certain of its affiliates. Those lawsuits were filed by investors who made investments through an affiliate of the Manager, and relate to the alleged investment fraud perpetrated by Bernard Madoff and his firm (“Madoff ”). Those suits allege a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and an award of attorneys’ fees and litigation expenses. None of the suits have named the Distributor, any of the Oppenheimer mutual funds or any of their independent Trustees or Directors as defendants. None of the Oppenheimer funds invested in any funds or accounts managed by Madoff.

7. Pending Litigation Continued

     The Manager believes that the lawsuits described above are without legal merit and is defending against them vigorously. The Defendant Funds’ Boards of Trustees have also engaged counsel to defend the suits brought against those Funds and the present and former Independent Trustees named in those suits. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer funds.
