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	$	311	$	494	$	693	$	1,266	$	311	$	494	$	693	$	1,266
Class C	$	265	$	512	$	883	$	1,926	$	165	$	512	$	883	$	1,926
Class Y	$	63	$	196	$	341	$	764	$	63	$	196	$	341	$	764

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 Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16% of the average value of its portfolio.

Principal Investment Strategies. Currently, under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in securities that pay interest that is, in the opinion of bond counsel to the issuer at the time the security is issued, exempt from federal individual income tax. Securities that generate income subject to the alternative minimum tax ("AMT") will count toward this 80% requirement, however, the Fund will not invest more than 5% of its net assets in securities that produce income subject to the AMT.
     The Fund invests primarily in municipal bonds, municipal notes and interests in municipal leases and commercial paper issued by the governments of states, their political subdivisions (such as cities, towns and counties), the District of Columbia, or by their agencies, instrumentalities and authorities. Those securities may be "general obligation" bonds that are secured by the issuer's full faith and credit or "revenue obligations" that are payable only from a particular facility or other revenue source. The Fund can borrow money to purchase additional securities, creating "leverage" of up to one third of its total assets.
     As of January 25, 2014, 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 regular federal individual and, as applicable, the Fund's state income tax. The Fund selects investments with regard to the AMT. The Fund will not invest more than 5% of its net assets in securities that produce income subject to the AMT.
     The Fund invests in municipal securities issued by the governments of states, their political subdivisions (such as cities, towns, counties, agencies and authorities) and the District of Columbia, U.S. territories, commonwealths and possessions or by their agencies, instrumentalities and authorities. These primarily include municipal bonds (long-term (more than one-year) obligations), municipal notes (short-term obligations), interests in municipal leases, and tax-exempt commercial paper. 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. The Fund can borrow money to purchase additional securities, creating "leverage" of up to one third of its total assets.
     The Fund seeks to maintain a dollar-weighted average effective portfolio maturity of two years or less; however, it can buy securities that have short, intermediate or long maturities. A substantial percentage of the securities the Fund buys may be "callable," meaning that the issuer can redeem them before their maturity date. Because of events affecting the bond markets and interest rate changes, the maturity of the portfolio might not meet that target for temporary periods.
     The Fund will not invest more than 5% of its total assets in securities that are rated below investment grade (sometimes referred to as "junk bonds") by a nationally recognized statistical rating organization, such as Standard & Poor's, or, if unrated, assigned a comparable rating by the Sub-Adviser, OppenheimerFunds, Inc. The Fund also will not invest more than 15% of its total assets in securities rated below the top three investment grade categories. For unrated securities, the Sub-Adviser may internally assign ratings to those securities in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations, after assessing their credit quality and other factors. There can be no assurance, nor is it intended, that the Sub-Adviser's credit analysis process is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. The Fund will not invest more than 5% of its total assets in securities that are unrated by a nationally recognized statistical rating organization. However, this limitation does not apply to an unrated security that the Sub-Adviser, in its discretion, determines to be comparable to another security (i) that has substantially similar characteristics, (ii) that is comparable in priority and security (if applicable), (iii) that is issued by the same issuer or guaranteed by the same guarantor, and (iv) that is rated by a nationally recognized statistical rating organization.
     In selecting investments for the Fund, the portfolio managers generally look for high current income; favorable credit characteristics; a wide range of issuers including different municipalities, agencies, sectors and revenue sources; unrated bonds or securities of smaller issuers that might be overlooked by other investors; and special situations that may offer high current income or opportunities for value. The portfolio managers may consider selling a security if any of these factors no longer applies, but are not required to do so.

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 because of poor investment 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 interest rate risk, duration risk, credit risk, credit spread risk, extension risk, reinvestment risk and prepayment risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may be worth less than the amount the Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are at, or near, historic lows. Duration risk is the risk that longer-duration debt securities will be more volatile and more likely to decline in price in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the 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 repay principal, the Fund's income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer's credit rating, for any reason, can also reduce the market value of the issuer's securities. "Credit spread" is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund's lower-rated and unrated securities. Some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price. Extension risk is the risk that an increase in interest rates could cause principal payments on a debt security to be repaid at a slower rate than expected. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security's call date. Such a decision by the issuer could have the effect of lengthening the debt security's expected maturity, making it more vulnerable to interest rate risk and reducing its market value. 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. Prepayment risk is the risk that the issuer may redeem the security prior to the expected maturity or that borrowers may repay the loans that underlie these securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to the expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income.

Municipal Market Volatility and Illiquidity. The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund's books. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds' prices.

Municipal Sector Focus Risk. The Fund will not concentrate its investments in issuers in any one industry. The Securities and Exchange Commission has taken the position that investment of more than 25% of a fund's total assets in issuers in the same industry constitutes concentration in that industy. Many 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 those types of municipal securities. Those municipal securities may finance or pay interest from the revenues of projects that are subject to similar economic, business or political developments that could increase their credit risk. Education, hospitals, healthcare and housing are some examples of sectors that may include similar types of projects or revenue streams. Legislation that affects the financing of a particular municipal project, or economic factors that have a negative impact on a project, would be likely to affect many other similar projects.

Special Risks of Investing in U.S. Territories, Commonwealths and Possessions. The Fund also invests in obligations of the governments of the U.S. territories, commonwealths and possessions such as Puerto Rico, the U.S. Virgin Islands, Guam, or the Northern Mariana Islands to the extent such obligations are exempt from regular federal individual income taxes. Accordingly, the Fund may be adversely affected by local political, economic and social conditions and developments within these U.S. territories, commonwealths and possessions affecting the issuers of such obligations.

Certain of the municipalities in which the Fund invests, including Puerto Rico, currently experience significant financial difficulties. A credit rating downgrade relating to, default by, or insolvency or bankruptcy of, one or several municipal security issuers of a state, territory, commonwealth or possession in which the Fund invests could affect the market values and marketability of many or all municipal obligations of such state, territory, commonwealth or possession.

Main Risks of Shorter-Term Securities. Normally, when interest rates change, the values of shorter-term debt securities change less than the values of securities with longer maturities. The Fund tries to reduce the volatility of its share prices by seeking to maintain a shorter average effective portfolio maturity. However, shorter-term securities may have lower yields than longer-term securities. Shorter-term securities are also subject to extension and reinvestment risk. The Fund is subject to extension risk when principal payments on a debt security occur at a slower rate than expected, potentially extending the average life of the security. For securities with a call date in the near future, there is the risk that an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security's call date. Such a decision by the issuer may effectively change a short- or intermediate-term security into a longer term security, which could have the effect of locking in a below-market interest rate on the security, increasing the security's duration, making the security more vulnerable to interest rate risk, reducing the security's market value and increasing the Fund's average effective portfolio maturity. Under such circumstances, because the values of longer term securities generally fluctuate more widely in response to interest rate changes than shorter term securities, the Fund's volatility could increase. Reinvestment risk is the risk that if interest rates fall the Fund may need to invest the proceeds of redeemed securities in securities with lower interest rates.

Risks of Non-Diversification. The Fund is classified as a "non-diversified" fund under the Investment Company Act of 1940. Accordingly, 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 than a fund that invests more widely.

Main Risks of Borrowing and Leverage. The Fund can borrow up to one-third of the value of its assets (including the amount borrowed), as permitted under the Investment Company Act of 1940. It can use those borrowings for a number of purposes, including purchasing securities, which creates "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. Borrowing for investment purposes might reduce the Fund's return if the yield on the securities purchased is less than those borrowing costs. The Fund may also borrow to meet redemption obligations or for temporary and emergency purposes. The Fund participates in a line of credit with other Oppenheimer funds for its borrowing.

The Fund can participate in a committed reverse repurchase agreement program. Reverse repurchase agreements that the Fund may engage in also create leverage. A reverse repurchase agreement is the sale by the Fund of a debt obligation to a party for a specified price, with the simultaneous agreement by the Fund to repurchase that debt obligation from that party on a future date at a higher price. Similar to a borrowing, reverse repurchase agreements provide the Fund with cash for investment and operational purposes. When the Fund engages in reverse repurchase agreements, changes in the value of the Fund's investments will have a larger effect on its share price than if it did not engage in these transactions due to the effect of leverage. Reverse repurchase agreements create fund expenses and require that the Fund have sufficient cash available to repurchase the debt obligation when required. Reverse repurchase agreements also involve the risk that the market value of the debt obligation that is the subject of the reverse repurchase agreement could decline significantly below the price at which the Fund is obligated to repurchase the security.

Who Is the Fund Designed For? The Fund is designed for investors seeking tax-free income. Because it invests in tax-exempt securities, the Fund is not appropriate for a retirement plan or other tax-exempt or tax-deferred account. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

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.
