The performance data quoted represents past performance, which does not guarantee future results. The investment return and principal value of an investment in the Fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Current performance and expense ratios may be lower or higher than the data quoted. All fund returns include change in share price, reinvested distributions and the sales charges as listed below, unless "without sales charge" is indicated. Returns do not consider capital gains or income taxes on an individual's investment. Class A Share returns include a maximum sales charge of 5.50% (equity), 4.25% (most fixed income), 3.25% (Senior Floating Rate Fund, Senior Floating Rate Plus), 2.50% ("limited term" fixed income funds) and 0% (Money Market Funds). Class B Share returns include contingent deferred sales charge as follows: For years 1 - 6 respectively, charges are 5%, 4%, 3%, 3%, 2%, 1% except for "limited term" fixed income funds (4%, 3%, 2%, 2%, 1%, 0%) and Senior Floating Rate (3%, 2% 1.5%, 1.5%, 1%, 0%). Class C Share returns include a 1% contingent deferred sales charge and are subject to an annual asset-based sales charge of 0.75%. Class R are subject to an annual asset-based sales charge of 0.25%. Annual asset-based sales charges are applied as follows: 0.75% on Class B/C; and 0.25% for Class R shares. Prior to 7/1/14, Class R shares were named Class N shares and were subject to a 1% CDSC (18 months). Class Y shares are not subject to a sales charge.
As the result of a reorganization on May 24, 2019, the returns of the fund for periods on or prior to May 24, 2019 reflect performance of the Oppenheimer predecessor fund. Share class returns will differ from the predecessor fund due to a change in expenses and sales charges.
Class W and Class I shares were reorganized into Class Y and Class R6 shares, respectively.
Performance shown prior to the inception date of Class R5 shares is that of Class A shares and includes the 12-b1 fees applicable to Class A shares. Class R5 shares have no sales charge; therefore, performance is at NAV.
On 2/22/2008 and 3/31/2008 for RWL, the last trade price was used to calculate market return because 4:00pm EST midpoint bid/ask prices are not available on those dates. On 9/30/2008, the last trade price for RWL was used to calculate market return because an uncorrected, failed trade resulted in an incorrect 4:00pm EST midpoint bid/ask price on that date. On 2/22/2008 and 3/31/2008 for RWJ, the last trade price was used to calculate market return because 4:00pm EST midpoint bid/ask prices are not available on those dates.
The NAV return is based on the net asset value of the Fund and the market return (MKT) is based on the market price per share of the Fund. The price used to calculate MKT is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which the shares of the Fund are listed for trading when the Fund's NAV is calculated at market close. MKT and NAV assume dividends and capital gain distributions have been reinvested in the Fund at market price and NAV, respectively. Returns less than one year are cumulative.
Mutual funds and exchange traded funds are subject to market risk and volatility. Shares may gain or lose value.

14. The funds invest in below-investment-grade debt securities, which may entail greater credit risks, as described in each fund’s prospectus. These securities (sometimes called “junk bonds”) may be subject to greater price fluctuations and risks of loss of income and principal than investment-grade municipal securities. The funds may invest substantially in municipal securities within a single state or related to similar type projects, which can increase volatility and exposure to regional issues.
15. Before June 29, 2018, Oppenheimer Short Term Municipal Fund was known as Oppenheimer Rochester Short Term Municipal Fund, and Oppenheimer Intermediate Term Municipal Fund was known as Oppenheimer Rochester Intermediate Term Fund. Effective June 29, various changes were made to each fund’s prospectus. Past performance, therefore, is not indicative of future results. Investors are encouraged to review each fund’s prospectus and summary prospectus for additional details.
16. The net expense ratio represents the Fund's gross expense ratio less certain interest and related expenses from the Fund's investments in inverse floaters, as reported in the latest prospectus. Under accounting rules, the Fund recognized additional income in an amount that offsets these expenses; the Fund's total returns and net asset values are not affected by those offsets.
17. The net expense ratio is not the result of a fee waiver or expense reimbursement.
18. Before October 15, 2018, Oppenheimer Municipal Fund was known as Oppenheimer Rochester Minnesota Municipal and, under normal market conditions, invested at least 80% of its net assets (plus borrowings for investment purposes) in Minnesota municipal securities. On October 15, 2018, the Fund changed its investment strategy from a strategy focused on investing in Minnesota municipal securities to a national municipal bond strategy. Past performance, therefore, is not indicative of future results.
19. Available to investors only in certain states.
A. The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product 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. <b>The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics.</b> The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Ratings do not consider sales charges and are subject to change monthly. <strong>Past performance is no guarantee of future results</strong></p>↩
