An Important Update

to the Fund Performance Discussion

Update (as of May 11, 2016): In the weeks that followed the end of this reporting period, several developments occurred that we believe warrant attention from this Fund’s shareholders:

Issuers of Puerto Rico debt made $59 million of the $60 million in bond and note payments that were due April 1, 2016. The Puerto Rico Public Finance Corporation (PFC), which stopped making payments on August 1, 2015, failed to honor its April 1 debt-service obligation.

On April 4, 2016, reports that the Government Development Bank (the GDB) had established new bank accounts prompted some investors to file a lawsuit in the U.S. District Court for Puerto Rico. The suit seeks a court order to prevent the GDB from diverting money into the new accounts.

The next day, Gov. Alejandro García Padilla proposed that he should be given the authority to declare a debt moratorium on all bonds issued by the Commonwealth’s public sector entities, including general obligation (G.O.) securities and bonds backed by sales tax revenues (COFINAs). The Puerto Rico Senate passed the measure in the early hours of April 5, the Puerto Rico House approved it the following day and the governor then signed it into law.

Stephen Spencer, a financial advisor to bondholders, including OppenheimerFunds, said the step “could have unintended consequences and could ultimately prove harmful to the commonwealth’s citizens as well as bondholders.” Mr. Spencer also said that the new law threatened the agreement OppenheimerFunds and other bondholders had reached with PREPA, Puerto Rico’s electric utilities authority.

Soon after, Puerto Rico legislators began debating amendments that could make many Commonwealth securities ineligible for the debt moratorium. While the Puerto Rico House approved some exemptions, the Senate has not voted on the amendments. Meanwhile, the governor declared a state of emergency for the GDB, halting payments to all but “essential services.” We believe that action by the U.S. Congress, if it passes a bill that is signed by the President, could supersede Puerto Rico’s debt moratorium law. Also during April, a group of G.O. bondholders offered a debt-relief plan that included $750 million of new G.O.s; the Commonwealth came forth with revisions to its “voluntary” exchange offer; the Natural Resources Committee postponed its vote on Puerto Rico-related legislation, and the GDB was said to be in negotiations to reduce the par value of about $120 million of its debt by 47%.

3      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

Things heated up when the governor announced that he had signed an executive order on April 30 to declare a moratorium on part of the GDB’s debt. The GDB defaulted on a $367 million principal payment on May 2 after reaching tentative forbearance agreements with two creditor groups. This Fund does not hold any securities issued by the GDB. Oppenheimer Rochester Limited Term California Municipal Fund is the only fund in our complex with a GDB position, and its market value is less than one-hundredth of 1% of that fund’s assets.

Also during May, the Puerto Rico House unanimously voted to cancel a planned 4 percentage point increase in a business-to-business tax and to delay plans to shift to a value-added tax (VAT); a new corporation was established to help PRASA, the Commonwealth’s aqueduct and sewer authority, borrow for capital needs, and an agreement for PREPA to sell $111 million in 3-year notes to bondholders and insurance companies appeared to be on the rocks amid concerns about how the debt moratorium law could affect future debt payments.

In Washington, D.C., legislators remained at odds about how to address Puerto Rico’ s financial problems. On May 11, Rep. Nancy Pelosi said that House Democrats were “disappointed” in the latest version of the Republicans’ bill and that “another few days of back and forth” were still necessary. As of this writing, it was not clear when the measure would be discussed in committee or when it might reach the floor for a vote.

Our team continues to be an active participant in negotiations with Puerto Rico officials. Shareholders should be confident that we will continue to work to protect our shareholders’ best interests.

Fund Performance Discussion

Oppenheimer Rochester Arizona Municipal Fund provided high levels of tax-free income during the 12-month reporting period that ended March 31, 2016, despite the persistence of low interest rates. The Fund’s Class A shares generated a distribution yield of 4.54% at net asset value (NAV) at the end of this reporting period. The Fund’s Class A shares were ranked in the top 3% in Lipper’s Other States Municipal Debt Funds category for distribution yield as of the end of March 2016, and a taxable investment would have had to yield more than 6.96% to provide a greater benefit for taxpayers in Arizona’s highest 2016 income tax bracket. Tax-free income comprised 100% of the Fund’s total return this reporting period.

MARKET OVERVIEW

After its March 2016 meeting, the Federal Reserve Open Market Committee (FOMC) announced that the Fed Funds target interest rate would remain between 0.25% and 0.50%. Citing “global economic and financial developments that continue to pose risks,” the Fed also indicated that its members foresee two increases in this short-term rate during 2016, not four, as was mentioned in December 2015, when the Fed Funds target rate was increased to the range of 0.25% to 0.50%.

The average distribution yield in Lipper’s Other States Municipal Debt Funds category was 3.01% at the end of this reporting period. At 4.54%, the distribution yield at NAV for this Fund’s Class A shares was 153 basis points higher than the category average.

In a statement following that increase, which occurred seven years to the day after it had been reduced to the range of zero to 0.25%, the Fed said steady job growth and a

near-normal unemployment rate of 5% were factors in its decision. The last increase – to 5.25% – was announced June 29, 2006. Fed officials also said they expected the economy to warrant only “gradual increases” over the next few years; in December 2015, FOMC members projected rate increases of one percentage point per year. At the time, the Fed suggested four rate hikes in 2016 but stressed that “rate increases could be faster or slower, based on economic data.”

In a speech late in this reporting period, Fed chair Janet Yellen returned to that theme, saying that “given the risks to the outlook, I consider it appropriate to proceed cautiously in adjusting policy.”

Throughout this reporting period, market watchers speculated about the timing and nature of FOMC decisions. Many predicted the FOMC would raise the Fed Funds target rate at the September 2015 meeting, but the Fed decided otherwise, citing “underutilization of labor resources and inflation continuing to run below the committee’s longer-run objective.”

In a speech after the September meeting, Ms. Yellen tried to quell the resulting market volatility saying, “it will likely be appropriate to raise the target range of the Federal Funds rate sometime later this year, and to continue boosting short-term rates at a gradual pace thereafter as the labor market improves further and inflation moves back to our 2% objective.” While not definitive by any measure, the statement was more

specific than earlier announcements from the Fed. In November 2015, Ms. Yellen again indicated that the central bank would bump up rates slowly, and the Fed kept interest rates unchanged at the January 2016 meeting. At the time, the FOMC noted that economic growth had slowed since late 2015 and that inflation was running below the FOMC’s target level. While the 12-month core inflation rate (excluding food and energy prices) was 2.3% in January 2016, the Fed’s preferred inflation gauge for the same period was just 1.3%.

We remind investors that a change in the Fed Funds rate does not automatically translate into a change in longer-term interest rates, which are determined by the marketplace. No matter what the Fed does, this Fund’s investment team will seek to meet investors’ desires for competitive levels of tax-free income by searching for value in the muni market.

On March 31, 2016, yields on high-grade municipal bonds at the short end of the yield curve were higher than they had been a year earlier. However, prices of longer-term, high-grade munis rallied during the same period, and their yields declined.

The average yield on 30-year, AAA-rated muni bonds was 2.79% on March 31, 2016, down 15 basis points from March 31, 2015. The average yield on 10-year, AAA-rated muni bonds was 1.79% on March 31, 2016, down 26 basis points from the March 2015 date, and the average yield on 1-year, AAA-rated

6      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

muni bonds was 0.44%, up 22 basis points from the March 2015 date.

At the beginning of 2016, Gov. Doug Ducey unveiled his $9.5 billion budget proposal for fiscal year 2017. The governor intends to allocate new money to universities, K-12 education, private prisons, child-welfare programs, a center that aims to reduce the prison population, and a task force to target drug and human smugglers. The governor’s proposal does not mention any cuts to income taxes.

In February 2016, Gov. Doug Ducey signed legislation to overhaul the state’s pension system but the changes will only affect law enforcement personnel and firefighters who are hired after July 1, 2017. The law requires these new hires to work until the age of 55 to qualify for full pension benefits and calls for these employees to pay half of their pension costs. On May 17, voters will have their say about tying cost-of-living adjustments for retirees’ benefits to a regional inflation rate but capping the adjustment at 2%. The law had bipartisan support in the Arizona Legislature and won the praise of the Retirement Security Initiative (RSI). One RSI principal called the reforms “a major victory for Arizona taxpayers and public workers.”

The cuts made to K-12, community college and university funding in fiscal year 2016, along with increased tax revenues, have left Arizona with a $325 million surplus; revenues were about $200 million ahead of forecast. Legislators have said that they are hoping

to restore much of what was cut during the recession, particularly state aid to public schools.

On August 22, 2015 – seven months ahead of schedule and on budget, the Central Mesa light rail extension began service. Construction of the additional 3.1-miles of service into downtown Mesa began in the summer of 2012, and more than 700 jobs were created annually. Funding of the extension was provided by a $75 million grant from the Federal Transit Administration, $71 million in countywide transportation tax funds and $53 million in federal air quality funds.

Phoenix voters approved a $31.7 billion, 35-year transportation plan in August 2015 that called for a tripling of Valley Metro’s light rail system, additional buses and upgrades to city streets. The plan will be funded by extending and increasing a special city sales tax. First approved in 2000 to build the first 20 miles of the light rail system, the tax was raised to 0.7%, from 0.4%, on January 1, 2016, and will stay on the books through 2050. The higher sales tax is expected to generate $17.3 billion through 2050 for transportation.

As of March 31, 2016, Arizona’s general obligation (G.O.) bonds were rated Aa2 by Moody’s Investors Service and AA by Standard & Poor’s. G.O.s are backed by the full faith and taxing authority of the state or local government that issues them.

Successful investors, we have found, maintain a long-term perspective regardless of the

7      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

specific developments associated with any given reporting period. To maximize the benefits that municipal bond funds seek to provide, many investors reinvest their dividends and allow the income generated from their investments to compound over time.

FUND PERFORMANCE

Oppenheimer Rochester Arizona Municipal Fund held more than 100 securities as of March 31, 2016. The Fund was invested in a broad range of sectors, providing shareholders with a diversity of holdings that we believe would be difficult and costly to replicate in an individual portfolio.

Market conditions created pressure on the dividends of many fixed-income funds this reporting period. This Fund’s Class A dividend, which was 4.8 cents per share at the outset of the reporting period, was reduced to 4.4 cents per share beginning with the May 2015 payout and to 3.9 cents per share with the February 2016 payout. In all, the Fund distributed 52.2 cents per Class A share this reporting period.

At the end of March 2016, the Fund’s Class A shares were ranked in the top 3% in Lipper’s Other States Municipal Debt Funds category for distribution yield at NAV.

The tax-exempt status of the Fund’s distributions of net investment income was a boon to investors seeking competitive levels of tax-free income. For a taxable investment

to have provided a greater benefit than an investment in this Fund, it would have had to yield more than 6.96%, based on the Fund’s standardized yield as of March 31, 2016, and the top federal and Arizona income tax rates for 2016. As long-time investors know, yields on fixed-income funds rise when share prices fall, and yields have historically contributed the lion’s share of the long-term total returns generated by bonds.

As of March 31, 2016, the Fund’s land development (or “dirt”) bonds included land-secured G.O.s and Special Assessment bonds, which help finance the infrastructure needs of new real estate development. These holdings typically offer very attractive yields, which in turn can help the Fund generate high levels of tax-free income.

The Fund’s G.O. debt represented 35.8% of the Fund’s total assets (37.6% of net assets) and the majority of the G.O. securities were issued by local land development districts with special taxing authority. The Fund’s G.O. holdings also include some “plain vanilla” bonds that are not related to the state’s land development projects; these G.O.s include bonds issued in various municipalities in Arizona and the Commonwealth of Puerto Rico and contributed positively to the Fund’s performance this reporting period. While they have not been tested before a court, the legal protections for Puerto Rico’s G.O. debt are strong, we believe, and many of our funds have overweight positions in these bonds.

   The Rochester Portfolio Management Team

The rest of the Funds’ “dirt” bonds were Special Assessment bonds, which represented 8.5% of the Fund’s total assets (8.9% of net assets). Overall, we believe that Special Assessment bonds issued in Arizona have several appealing characteristics: The special assessment payments securing these bonds are senior to mortgage payments, and assessments or taxes must be paid by whoever owns the land when the tax bill comes due. Additionally, we continue to

believe that improvements in the housing market and the general economy could further strengthen the credit profiles of this sector. The Fund’s Special Assessment bond sector contributed positively to performance this reporting period.

Securities issued in the Commonwealth of Puerto Rico, which are exempt from federal, state and local income taxes, represented 18.5% of the Fund’s total assets (19.4% of

9      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

   The Rochester Credit Research Team

10      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

net assets) at the end of this reporting period. Puerto Rico’s “tobacco bonds” are excluded from this figure, as they are backed by proceeds from the tobacco Master Settlement Agreement (MSA) and included in this Fund’s tobacco holdings. The Fund’s Puerto Rico holdings, some of which are insured, include G.O. debt and securities from many different sectors. In aggregate, the Fund’s holdings of bonds issued in Puerto Rico detracted from the Fund’s total return during this reporting period.

Most of the Fund’s investments in securities issued in Puerto Rico are supported by taxes and other revenues and are designed to help finance electric utilities, highways and education, among other things. At the beginning of 2016, the Commonwealth made virtually all of the nearly $1 billion in payments due. A full payment of $368 million was received to cover the debt-service obligations on Puerto Rico’s G.O. securities. PREPA (Puerto Rico’s electric utility authority) also made a full payment of $215 million.

Two authorities, the Puerto Rico Public Finance Corporation (PFC) and the Puerto Rico Infrastructure and Finance Authority (PRIFA), defaulted on $37 million. According to Gov. Alejandro García Padilla, these defaults were the result of the emergency measure he authorized to divert revenue and use it to ensure that other debt was paid in full. The Puerto Rican government decided not to make the PFC appropriation, and PRIFA revenues were subject to a “claw back.” Three bond insurers – Ambac, Assured Guaranty

and FGIC – have sued the Commonwealth, arguing that the revenues should not have been diverted. On January 31, 2016, the Commonwealth filed a motion to dismiss the suits filed by Ambac and Assured Guaranty, which were joined.

Puerto Rico remained in the news throughout this reporting period. On August 21, 2015, the Commonwealth petitioned the U.S. Supreme Court to overturn a February 6, 2015 federal district court ruling that the Puerto Rico Public Corporation Debt Enforcement and Recovery Act (the “Recovery Act”) violated the U.S. Constitution and was invalid. As you may recall, the Recovery Act was passed in late June 2014 and the Oppenheimer Rochester municipal bond funds filed suit immediately, challenging the legislation that was designed to allow PREPA, PRASA (Puerto Rico’s aqueduct and sewer authority) and PRHTA (its highway authority) to restructure their debt under the supervision of a Commonwealth court. Five months later, a federal appeals court unanimously affirmed the judge’s decision.

In its petition, the Commonwealth argued that Puerto Rico’s issuers should have the right to restructure their debt pursuant to the terms set forth in the Commonwealth’s Recovery Act. As bondholders, we see things differently: The Commonwealth and its issuers agreed to specific and carefully constructed bond covenants when they sold securities, and the contracts should be honored.

11      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

On December 4, 2015, the U.S. Supreme Court agreed to hear the Commonwealth’s appeal of the district court and appellate court decisions. At the March 22, 2016 hearing, much of the discussion centered on a 1984 amendment to Chapter 9 bankruptcy code, which does not allow Puerto Rico municipalities or public corporations to file for Chapter 9 bankruptcy protection. If the Court overturns the lower courts’ decisions, the case would likely be remanded to U.S. Federal District Court, where bondholders would have an opportunity to present additional arguments. Although we cannot guarantee that Oppenheimer Rochester will once again prevail, we continue to believe our legal arguments are strong and wish to assure shareholders that our team will always stand up for bondholders’ best interests. A Supreme Court ruling on the Commonwealth’s petition is expected in June 2016.

Throughout this reporting period, the market also reacted to developments related to the forbearance agreement that was reached in August 2014 between PREPA and many of its creditors, including this Fund. In the agreement, which was extended several times beyond March 31, 2015, its initial expiration date, the bondholders agreed to forbear from exercising rights in connection with events that would constitute a default on PREPA bonds, and PREPA agreed to a variety of financial terms, to make its July 1, 2015 payment and to reach a comprehensive restructuring plan with its creditors by September 1, 2015.

Investors should note that the plan also seeks to reduce and/or restructure some of Puerto Rico’s debt. In a televised address, the governor said, “The plan itself will not get us out of the hole we find ourselves in. It’s time that creditors come to the table and share in the sacrifice.” We continue to believe that Puerto Rico must act within the tenets of the law, including its Constitution. Questions about the degree to which Puerto Rico and its agencies and authorities are committed to honoring their debt-service obligations continued to create significant pressure on the prices of their securities.

On September 1, 2015, PREPA and the forbearing bondholders reached an agreement in principle on the major financial terms of a securitization transaction to lower PREPA’s debt service costs. Although the proposed agreement would result in a reduction in the par value of PREPA’s existing bonds, we nevertheless believe the agreement – if implemented – will be a win for bondholders, PREPA and Puerto Ricans.

Investors should note that the new bond structure would be bankruptcy remote, which serves to protect bondholders from event risks; that the term sheet required that the new securitization bonds earn an investment-grade rating; that the deal requires approval by the Puerto Rico Legislature and high participation by all bondholders; and that insurers reach agreement with PREPA on the treatment of the insured bonds. If all goes as planned, bondholders will be further insulated from the risks and uncertainties related to

12      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

any inefficiency in PREPA’s operations and will not incur the costs that would result from a lengthy and uncertain litigation process. While we expect that all parties will work toward a restructuring support agreement, we remind investors that there is no guarantee of either a timeline or implementation.

In December 2015, after gaining several extensions related to the debt-restructuring agreement, PREPA announced that it had reached agreement with at least 70% of its creditors and its bond insurers.

PREPA and its forbearing bondholders, a group that includes the Oppenheimer Rochester funds, set a January 21, 2016 deadline for the Puerto Rico Legislature to approve legislation related to the debt-restructuring agreement. No vote was taken by that date, and PREPA asked for an extension to February 12.

The forbearing bondholders responded that the extension and a loan of $115 million were contingent on the approval of a surcharge for PREPA customers. After some back and forth, creditors agreed to provide $111 million of financing through the purchase of new bonds – half to be provided after the passage of the debt-restructuring legislation and the remainder after the securitization structure has been submitted to the Energy Commission for approval. PREPA accepted these terms and the deadline for the legislative vote was extended to February 16. The governor signed the debt-restructuring legislation and PREPA was given until

March 1 to submit a rate proposal to the Commonwealth’s Energy Commission. That deadline has since been extended to April 22.

Also late in this reporting period, the Puerto Rico House passed legislation that would allow PRASA to issue new debt and avoid a rate hike. As of March 31, 2016, the Puerto Rico Senate had yet to vote on the legislation, which includes several prerequisites.

The Oppenheimer Rochester team has been an active participant in negotiations with Puerto Rico officials, and shareholders should be confident that we will continue to work to protect their best interests.

Meanwhile, in Washington, a December 1, 2015 hearing of the U.S. Senate Committee on the Judiciary, which is chaired by Sen. Chuck Grassley of Iowa, focused on Puerto Rico’s financial and economic circumstances. While Gov. Padilla pressed the senators to consider giving the Commonwealth access to Chapter 9 bankruptcy and asserted that “we have no cash left,” Sen. Grassley was among those who chided the governor because audited financial statements had not been provided. Sen. Grassley, in line with other Republican senators challenged the governor, saying “Let’s not forget that Puerto Rico issued its bonds with the knowledge that Ch. 9 bankruptcy wasn’t an option in the event of a default.” At the end of this reporting period, Democratic lawmakers had not gained traction on their proposals to allow the Commonwealth and/or its authorities to file for Ch. 9 bankruptcy protection.

13      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

On December 9, 2015, three Republican senators – Orrin Hatch of Utah, Lisa Murkowski of Alaska and Sen. Grassley of Iowa – introduced the Puerto Rico Assistance Act of 2015. The bill would establish a new authority that could issue bonds and called for as much as $3 billion to help the Commonwealth stabilize its budget and debt, among other provisions. A week later, House Speaker Paul Ryan asked lawmakers to reach a “responsible solution” for Puerto Rico by March 31, 2016; however, as of that date, no “solution” had been put forth.

There was also talk in Congress of amending the omnibus spending bill to provide Puerto Rico access to Ch. 9, but the only measures included in the bill were related to Medicare funding and additional technical assistance from Treasury. Meanwhile, the Government Development Bank for Puerto Rico (GDB) put forth a plan calling for a “comprehensive single transaction to be accomplished through a voluntary exchange offer.”

U.S. Senate Democrats introduced a number of bills in late March: The proposed Puerto Rico Stability Act, which would give the Commonwealth restructuring capabilities, establish a nine-person oversight authority, and require the appointment of a chief financial officer and the development of a 5-year fiscal plan, among other things. The proposed Puerto Rico Recovery Act of 2016 (not to be confused with the Recovery Act) would increase Medicaid funding and give island residents access to the Earned Income

Tax Credit. And the proposed Territories Relief Act would give territories bankruptcy protection. The status of all three proposed acts was unclear as of March 31, 2016.

Late in this reporting period, the House Committee on Natural Resources, which has jurisdiction over U.S. territories, released a discussion draft of a bill to address Puerto Rico’s financial problems. The draft called for an independent oversight board that would be allowed to file petitions for debt restructuring, but debtors would first have to release “their most recent audited financial report and engage in voluntary debt restructuring discussions with creditors,” according to The Bond Buyer. The draft was roundly criticized by most parties, including Republicans, Democrats, Puerto Rican officials, and creditors.

On March 8, 2016, the governor agreed to postpone until June 1 a 6.5 percentage point increase in the Commonwealth’s business-to-business service tax. This decision has delayed Puerto Rico’s transition to a value-added tax, originally slated to begin April 1. Meanwhile, there are calls for the Commonwealth’s tax system to be overhauled.

Politicians, including some candidates for the presidency, have voiced concerns about Puerto Rico, and we believe the situation will remain political in the near term. In fact, many of the recommendations would require action by the U.S. Congress and/or the Puerto Rico Legislature.

14      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

Our investment team will continue to monitor credit rating changes and other developments related to our Puerto Rico holdings closely. Investors should note that deterioration of the Puerto Rican economy could have an adverse impact on Puerto Rico bonds and the performance of the Oppenheimer Rochester municipal funds that hold them, including this Fund. Our team’s commitment to protecting the interests of our shareholders is unwavering.

Given the degree to which Oppenheimer Rochester funds have been cited in news coverage about the economic and fiscal challenges facing Puerto Rico, we feel compelled to remind investors that all fund investments are actively managed. Our team is responsive to the dynamics of the market and may choose to adjust trading strategies in the interest of maximizing the potential benefits to our shareholders. Further, while we remain committed to keeping investors informed about our basic investing strategies, we do not provide comment about near-term trading strategies as we believe doing so might allow other market participants to impair our team’s ability to deliver shareholder value.

Please note: An important update on post-reporting-period developments that could have implications for the Fund’s Puerto Rico holdings can be found on page 3 of this report.

As of March 31, 2016, 10.7% of the Fund’s total assets (11.2% of net assets) continued to be invested in the education sector. The bonds we hold in this sector have regularly provided high levels of tax-free income with what we believe to be far less credit risk than their external ratings would suggest. Holdings in this sector contributed positively to the Fund’s performance this reporting period.

Municipal bonds backed by proceeds from the tobacco MSA, the national litigation settlement with U.S. tobacco manufacturers, represented 10.0% of the Fund’s total assets (10.4% of net assets) at the end of this reporting period.

We believe the securities we hold in this sector are fundamentally sound credits, and we like that “tobacco bonds” can provide tax-exempt income for investors as well as benefits to the issuing states and territories. During this reporting period, our long-term view of the sector continued to be bullish and, given attractive valuations, we believe that it is likely we will continue to hold a greater percentage of tobacco bonds in our portfolios than our peers. As in prior reporting periods, the tobacco bonds this Fund held during this reporting period, all of which were issued in the Commonwealth of Puerto Rico and the U.S. Virgin Islands, made all scheduled payments of interest and principal on time and in full. The “tobacco bond” sector contributed positively to the Fund’s performance this reporting period.

15      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

The Fund’s holdings in municipal bonds issued by utilities represented 6.5% of total assets (6.7% of net assets) at the end of this reporting period. This set of holdings included electric utilities with 3.4% of total assets (3.5% of net assets) and water utilities with 3.1% of total assets (3.2% of net assets), as of March 31, 2016. Our holdings in these sectors consist of securities in the mid-range of the credit spectrum and include bonds issued in Arizona as well as securities issued by PREPA. The electric and water utilities sectors both contributed positively to the Fund’s performance this reporting period.

As of March 31, 2016 the sales tax sector represented 6.0% of the Fund’s total assets (6.3% of net assets). Debt-service payments on securities in this sector are paid using the issuing municipality’s sales tax revenue. Nearly all of the Fund’s assets in this sector were in bonds issued in Puerto Rico. Economic conditions in the territory were such that the sector detracted from the Fund’s total return this reporting period.

As of March 31, 2016, the Fund was invested in the hospital/healthcare sector, which represented 5.0% of total assets (5.2% of net assets). While the Fund invests across the credit spectrum in this sector, most of its holdings in this sector are investment grade; about one-third of the Fund’s assets in this sector were in bonds issued in Puerto Rico.

Securities in this sector contributed positively to the Fund’s performance this reporting period.

Many sectors in which the Fund maintained relatively smaller investments as of March 31, 2016, also contributed positively to performance. Investors benefited this reporting period from the Fund’s holdings in sectors focused on higher education, student loans, multifamily housing, marine/ aviation facilities, food products and U.S. government obligations, among others. (The U.S. government obligations sector includes any securities held by the Fund that have been pre-refunded. In a pre-refunding or refunding, new securities with lower coupon rates are sold by a municipality to pay off debt that has higher interest rates. When a municipality issues a pre-refunding bond, the proceeds are escrowed in U.S. Treasury bonds and earmarked to pay off a previously issued bond; Treasury bonds are backed by the full faith and credit of the U.S. government.) Some of these sectors included securities issued in Puerto Rico as of March 31, 2016.

The government appropriation, municipal leases sectors and highways/commuter facilities sectors detracted from the Fund’s performance this reporting period. The Fund’s holdings in these sectors were relatively small and included securities issued in Puerto Rico as of March 31, 2016.

Our approach to municipal bond investing is flexible and responsive to market conditions. Shareholders should note that market conditions during this reporting period did not affect the Fund’s overall investment goals or cause it to pay any capital gain distributions. In closing, we believe that the Fund’s structure and sector composition as well as our time-tested strategies will continue to benefit fixed-income investors through interest rate and economic cycles.

INVESTMENT STRATEGY

The Rochester investment team focuses exclusively on municipal bonds and has consistently used a time-tested, value-oriented and security-specific approach to fund management. We know that market conditions can and do fluctuate, but we do not waver in our belief in the power of tax-free yield to help investors achieve their long-term objectives.

This Fund invests primarily in investment-grade municipal securities. It may invest up to 25% of its total assets in below-investment grade securities, or “junk” bonds; the percentage of assets is measured at the time of purchase as is the credit quality of the securities. Additionally, the credit quality is based on Nationally Recognized Statistical Rating Organization (“NRSRO”) ratings or, if no NRSRO rating, on internal ratings. As of March 31, 2016, market movements or rating

changes of municipal bonds, notably the Fund’s investments in Puerto Rico paper, caused the Fund’s below-investment-grade holdings to exceed this threshold. As a result, no further purchases of below-investment-grade bonds will be made until the Fund’s holdings of these types of bonds is once again below 25% of total assets.

Our team continually searches for bonds that we believe are undervalued and can provide a meaningful level of tax-free income until maturity. Rather than making allocation shifts based on expected market conditions, we search the marketplace for what we believe to be the best values for generating income. It remains important to note that we do not manage our funds based on predictions of interest rate changes.

Instead, our investment approach involves scouring the market for municipal securities that meet our stringent credit criteria and buying bonds that we believe will deliver above-average yields relative to peer funds. We focus on identifying inefficiencies in market pricing that can lead to investment advantages. We seek to maintain a thoughtful mix of industry sectors, maturities and credit ratings in this Fund’s portfolio.

The Rochester team also prospects for yield-enhancing opportunities in the secondary market, often picking up odd lots that we

17      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

believe can add significant incremental yield to our portfolios. We will also look for non-rated issues with solid credit qualities, which we believe can often help enhance a fund’s tax-free yield. Investors should note that non-rated or unrated securities may or may not be the equivalent of investment grade securities.

The Rochester Way, we believe, distinguishes our approach to municipal investing from those of our competitors.

The percentages above are based on the market value of the securities as of March 31, 2016 and are subject to change. OppenheimerFunds, Inc. determines the credit allocation of the Fund’s assets using ratings by nationally recognized statistical rating organizations (NRSROs), such as Standard & Poor’s. For any security rated by an NRSRO other than S&P, the sub-adviser, OppenheimerFunds, Inc., converts that security’s rating to the equivalent S&P rating. If two or more NRSROs have assigned a rating to a security, the highest rating is used. For securities not rated by an NRSRO, the sub-adviser uses its own credit analysis to assign ratings in categories similar to those of S&P. The use of similar categories is not an indication that the sub-adviser’s credit analysis process is consistent or comparable with any NRSRO’s process were that NRSRO to rate the same security.

For the purposes of this Credit Allocation table, securities rated within the NRSROs’ four highest categories—AAA, AA, A and BBB—are investment-grade securities. For further details, please consult the Fund’s prospectus or Statement of Additional Information.

COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN:

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 their original cost. Current performance may be lower or higher than the performance quoted. Returns do not consider capital gains or income taxes on an individual’s investments. Returns for periods of less than one year are not annualized. For performance data current to the most recent month-end, visit oppenheimerfunds.com or call 1.800.CALL OPP (225.5677). Fund returns include changes in share price, reinvested distributions, and the applicable sales charge: for Class A shares, the current maximum initial sales charge of 4.75%; for Class B shares, the contingent deferred sales charge of 5% (1-year) and 2% (5-year); and for Class C, the contingent deferred sales charge of 1% for the 1-year period. There is no sales charge for Class Y shares. Because Class B shares convert to Class A shares 72 months after purchase, the 10-year return for Class B shares uses Class A performance for the period after conversion.

As of the close of the New York Stock Exchange on March 24, 2016, the purchase and exchange of shares of this Fund was restricted, subject to certain exceptions. Please see the prospectus supplement of this Fund for further information.

The Fund’s performance is compared to the performance of the Barclays Municipal Bond Index, an index of a broad range of investment-grade municipal bonds that is a measure of the general municipal bond market. The Fund’s performance is also compared to the Consumer Price Index, a non-securities index that measures changes in the inflation rate. Indices are unmanaged and cannot be purchased by investors. While index comparisons may be useful to provide a benchmark for the Fund’s performance, it must be noted that the Fund’s investments are not limited to the investments comprising the index. Index performance includes reinvestment of income, but does not reflect transaction costs, fees, expenses or taxes. Index performance is shown for illustrative purposes only as a benchmark for the Fund’s performance, and does not predict or depict performance of the Fund. The Fund’s performance reflects the effects of the Fund’s business and operating expenses.

Distribution yields for Class A shares are based on dividends of $0.039 for the 28-day accrual period ended March 22, 2016. The yield without sales charge for Class A shares is calculated by dividing annualized dividends by the Class A net asset value on March 22, 2016; for the yield with sales charge, the denominator is the Class A maximum offering price on that date. Distribution yields for Class B, C and Y are annualized based on dividends of $0.0331, $0.0331 and $0.039, respectively, for the 28-day accrual period ended March 22, 2016, and on the corresponding net asset values on that date.

Standardized yield is based on the Fund’s net investment income for the 30-day period ended March 31, 2016, and either that date’s maximum offering price (for Class A shares) or net asset value (for the other classes). Each result is compounded semiannually and annualized. Falling share prices artificially increase yields.

The average distribution yield in Lipper’s Other States Municipal Debt Funds category was calculated based on the distributions and the final net asset values (NAVs) of the reporting period for the funds in each category. The calculation included 266 NAVs, one for each class of each fund in the category; a fund can have up to 4 classes. Lipper yields do not include sales charges – which, if included, would reduce results.

Taxable equivalent yield is based on the standardized yield and the 2016 top federal and Arizona tax rate of 46.1%. Calculations factor in the 3.8% tax on unearned income under the Patient Protection and Affordable Care Act, as applicable. A portion of the Fund’s distributions may be subject to tax; distributions may also increase an investor’s exposure to the alternative minimum tax. Capital gains distributions are taxable as capital gains. Tax treatments of the Fund’s distributions and capital gains may vary by state; investors should consult a tax advisor to determine if the Fund is appropriate for them. Each result is compounded semiannually and annualized. Falling share prices artificially increase yields. This Report must be preceded or accompanied by a Fund prospectus.

The average yields for AAA-rated municipal securities are provided by Municipal Market Advisors (MMA) and are based on its benchmark of general obligation bonds structured with a 5% coupon. The MMA 5% benchmark is constructed using yields from the leading underwriters, who represent a significant percentage of the primary activity of the top 10 underwriters and therefore the total issuance.

Investments in “tobacco bonds,” which are backed by the proceeds a state or territory receives from the 1998 national litigation settlement with tobacco manufacturers, may be vulnerable to economic and/or legislative events that affect issuers in a particular municipal market sector. Annual payments by MSA-participating manufacturers, for example, hinge on many factors, including annual domestic cigarette shipments, inflation and the relative market share of non-participating manufacturers. To date, we believe consumption figures remain within an acceptable range of the assumptions used to structure MSA bonds. Future MSA payments could be reduced if consumption were to fall more rapidly than originally forecast.

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

Fund Expenses

Fund Expenses. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments and/or contingent deferred sales charges on redemptions; and (2) ongoing costs, including management fees; distribution and service fees; and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning of the period and held for the entire 6-month period ended March 31, 2016.

Actual Expenses. The first section of the table provides information about actual account values and actual expenses. You may use the information in this section for the class of shares you hold, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During 6 Months Ended March 31, 2016” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes. The second section of the table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio for each class of shares, and an assumed rate of return of 5% per year for each class before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or contingent deferred sales charges (loads). Therefore, the “hypothetical” section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Class Y		1,000.00		1,013.00		12.15

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended March 31, 2016 are as follows:

Class	Expense Ratios
Class A		2.45%
Class B		3.24
Class C		3.11
Class Y		2.40

The expense ratios reflect voluntary and/or contractual waivers and/or reimbursements of expenses by the Fund’s Manager. Some of these undertakings may be modified or terminated at any time, as indicated in the Fund’s prospectus. The “Financial Highlights” tables in the Fund’s financial statements, included in this report, also show the gross expense ratios, without such waivers or reimbursements and reduction to custodian expenses, if applicable.

1. Organization

Oppenheimer Rochester Arizona Municipal Fund (the “Fund”) is a diversified open-end management investment company registered under the Investment Company Act of 1940 (“1940 Act”), as amended. The Fund’s investment objective is to seek tax-free income. The Fund’s investment adviser is OFI Global Asset Management, Inc. (“OFI Global” or the “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”). The Manager has entered into a sub-advisory agreement with OFI. Effective as of the close of the New York Stock Exchange (“NYSE”) on March 24, 2016 (the “Closing Date”), the Fund will no longer accept purchase orders from new investors and shareholders of other Oppenheimer funds will no longer be able to exchange shares of other funds into the Fund. Please see the Fund’s prospectus for exceptions and additional information.

The Fund offers Class A, Class C and Class Y shares, and previously offered Class B shares for new purchase through June 29, 2012. Subsequent to that date, no new purchases of Class B shares are permitted, however reinvestment of dividend and/or capital gain distributions and exchanges of Class B shares into and from other Oppenheimer funds are allowed. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Class C shares are sold, and Class B shares were sold, without a front-end sales charge but may be subject to a contingent deferred sales charge (“CDSC”). Class Y shares are sold to certain institutional investors or intermediaries without either a front-end sales charge or a CDSC, however, the intermediaries may impose charges on their accountholders who beneficially own Class Y shares. 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 shares have separate distribution and/or service plans under which they pay fees. Class Y shares do not pay such fees. 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 followed in the Fund’s preparation of financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).

2. Significant Accounting Policies

Security Valuation. All investments in securities are recorded at their estimated fair value, as described in Note 3.

Reporting Period End Date. The last day of the Fund’s reporting period is the last day the New York Stock Exchange was open for trading during the period. The Fund’s financial statements have been presented through that date to maintain consistency with the Fund’s net asset value calculations used for shareholder transactions.

Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than those

39      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

2. Significant Accounting Policies (Continued)

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.

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. GAAP, 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 Prime Rate plus 0.35%. 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.

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 remains open for the three preceding fiscal reporting period ends. The Fund has analyzed its tax positions for the fiscal year ended March 31, 2016, including open tax years, and does not believe there are

40      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

2. Significant Accounting Policies (Continued)

any uncertain tax positions requiring recognition in the Fund’s financial statements.

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.

Undistributed Net Investment Income	Undistributed Long-Term Gain		Accumulated Loss Carryforward1,2,3,4		Net Unrealized Depreciation Based on cost of Securities and Other Investments for Federal Income Tax Purposes
$379,203		$—		$9,121,097		$5,575,537

1. At period end, the Fund had $9,121,097 of net capital loss carryforward available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. Details of the capital loss carryforwards are included in the table below. Capital loss carryovers with no expiration, if any, must be utilized prior to those with expiration dates.

Expiring
2017	$	1,909,891
2018		2,824,369
No expiration		4,386,837
Total	$	9,121,097

2. During the reporting period, the Fund did not utilize any capital loss carryforward.

3. During the previous reporting period, the Fund utilized $10,311 of capital loss carryforward to offset capital gains realized in that fiscal year.

4. During the reporting period, $117,136 of unused capital loss carryforward expired.

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 are determined in accordance with federal income tax requirements, which may differ from the character of net investment income or net realized gains presented in those financial statements in accordance with U.S. GAAP. 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 the reporting period. Net assets of the Fund were unaffected by the reclassifications.

Reduction to Paid-in Capital	Reduction to Accumulated Net Realized Loss on Investments
$117,136		$117,136

The tax character of distributions paid during the reporting periods:

	Year Ended         March 31, 2016		Year Ended         March 31, 2015
Distributions paid from:
Exempt-interest dividends	$	2,267,058	$	3,418,792
Ordinary income		36,175		18,546
Total	$	2,303,233	$	3,437,338

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 at period end 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	$	48,532,808
Gross unrealized appreciation	$	1,724,588
Gross unrealized depreciation		(7,300,125)
Net unrealized depreciation	$	(5,575,537)

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP 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.

3. 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, except in the case of a scheduled early closing of the Exchange, in which case the Fund will calculate net asset value of the shares as of the scheduled early closing time of the Exchange.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a “fair valuation” for any security for which market quotations are not “readily available.” The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

Valuation Methods and Inputs

Securities are valued using unadjusted quoted market prices, when available, as supplied

42      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

3. Securities Valuation (Continued)

primarily by third party pricing services or dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

Securities traded on a registered U.S. securities exchange (including exchange-traded derivatives other than futures and futures options) 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. In the absence of a sale, the security is valued at the mean between the bid and asked price on the principal exchange or, if not available from the principal exchange, obtained from two dealers. If bid and asked prices are not available from either the exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority): (1) a bid from the principal exchange, (2) the mean between the bid and asked price as provided by a single dealer, or (3) a bid from a single dealer. A security of a foreign issuer traded on a foreign exchange, but not listed on a registered U.S. securities exchange, is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the third party pricing service used by the Manager, prior to the time when the Fund’s assets are valued. If the last sale price is unavailable, the security is valued at the most recent official closing price on the principal exchange on which it is traded. If the last sales price or official closing price for a foreign security is not available, the security is valued at the mean between the bid and asked price per the exchange or, if not available from the exchange, obtained from two dealers. If bid and asked prices are not available from either the exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority): (1) a bid from the exchange, (2) the mean between the bid and asked price as provided by a single dealer, or (3) a bid from a single dealer.

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.

Corporate and government debt securities (of U.S. or foreign issuers) and municipal debt securities, event-linked bonds, loans, mortgage-backed securities, collateralized mortgage obligations, and asset-backed securities are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices.

Short-term money market type debt securities with a remaining maturity 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. Short-term debt securities with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers.

A description of the standard inputs that may generally be considered by the third party pricing vendors in determining their evaluated prices is provided below.

43      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

3. Securities Valuation (Continued)

Security Type	Standard inputs generally considered by third-party pricing vendors
Corporate debt, government debt, municipal, mortgage- backed and asset-backed securities	Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, and other appropriate factors.
Loans	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.
Event-linked bonds	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.

If a market value or price cannot be determined for a security using the methodologies described above, or if, in the “good faith” opinion of the Manager, the market value or price obtained does not constitute a “readily available market quotation,” or a significant event has occurred that would materially affect the value of the security, the security is fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Fair value determinations by the Manager are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined. Those fair valuation standardized methodologies include, but are not limited to, valuing securities at the last sale price or 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 further adjusted for any discounts related to security-specific 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 nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

To assess the continuing appropriateness of security valuations, the Manager, or its third party service provider who is subject to oversight by the Manager, regularly compares prior day prices, prices on comparable securities, and sale prices to the current day prices and challenges those prices exceeding certain tolerance levels with the third party pricing service or broker source. For those securities valued by fair valuations, whether through a standardized fair valuation methodology or a fair valuation determination, the Valuation Committee reviews and affirms the reasonableness of the valuations based on such methodologies and fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.

Classifications

Each investment asset or liability of the Fund is assigned a level at measurement date based

44      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

3. Securities Valuation (Continued)

on the significance and source of the inputs to its valuation. 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 or liability (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 or liability).

The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities at period end based on valuation input level:

The Manager periodically reviews pricing vendor methodologies and inputs to confirm they are determined using unobservable inputs and have been appropriately classified. Such securities’ fair valuations could change significantly based on changes in unobservable inputs used by the pricing service.

4. Investments and Risks

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. 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.

At period end, the Fund had sold securities issued on a delayed delivery basis as follows:

46      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

4. Investments and Risks (Continued)

	When-Issued or
	Delayed Delivery
	Basis Transactions
Sold securities		$30,390

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 that have missed an interest payment, and is not obligated to dispose of securities whose issuers or underlying obligors subsequently miss an interest payment.

Information concerning securities not accruing interest at period end is as follows:

Cost	$1,830,068
Market Value	$219,690
Market Value as% of Net Assets	0.52%

The Fund has entered into forbearance agreements with certain obligors under which the Fund has agreed to temporarily forego receipt of the original principal or coupon interest rates. At period end, securities with an aggregate market value of $711,551, representing 1.70% of the Fund’s net assets, were subject to these forbearance agreements.

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.

5. Market Risk Factors

The Fund’s investments in securities and/or financial derivatives may expose the Fund to various market risk factors:

Commodity Risk. Commodity risk relates to the change in value of commodities or commodity indexes as they relate to increases or decreases in the commodities market. Commodities are physical assets that have tangible properties. Examples of these types of assets are crude oil, heating oil, metals, livestock, and agricultural products.

Credit Risk. Credit risk relates to the ability of the issuer of debt to meet interest and principal payments, or both, as they come due. In general, lower-grade, higher-yield debt securities are subject to credit risk to a greater extent than lower-yield, higher-quality securities.

Equity Risk. Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

Foreign Exchange Rate Risk. Foreign exchange rate risk relates to the change in the U.S. dollar value of a security held that is denominated in a foreign currency. The U.S. dollar value of a foreign currency denominated security will decrease as the dollar appreciates

47      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

5. Market Risk Factors (Continued)

against the currency, while the U.S. dollar value will increase as the dollar depreciates against the currency.

Interest Rate Risk. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between price and yield. For example, an increase in general interest rates will tend to reduce the market value of already issued fixed-income investments, and a decline in general interest rates will tend to increase their value. In addition, debt securities with longer maturities, which tend to have higher yields, are subject to potentially greater fluctuations in value from changes in interest rates than obligations with shorter maturities.

Volatility Risk. Volatility risk refers to the magnitude of the movement, but not the direction of the movement, in a financial instrument’s price over a defined time period. Large increases or decreases in a financial instrument’s price over a relative time period typically indicate greater volatility risk, while small increases or decreases in its price typically indicate lower volatility risk.

6. 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:

8. 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

The Fund’s effective management fee for the reporting period was 0.55% of average annual net assets before any applicable waivers.

Sub-Adviser Fees. The Manager has retained the Sub-Adviser to provide the day-to-day portfolio management of the Fund. Under the Sub-Advisory Agreement, the Manager pays the Sub-Adviser an annual fee in monthly installments, equal to a percentage of the investment management fee collected by the Manager from the Fund, which shall be calculated after any investment management fee waivers. The fee paid to the Sub-Adviser is paid by the Manager, not by the Fund.

Transfer Agent Fees. OFI Global (the “Transfer Agent”) serves as the transfer and shareholder servicing agent for the Fund. The Fund pays the Transfer Agent a fee based on annual net assets. Fees incurred and average net assets for each class with respect to these services are detailed in the Statement of Operations and Financial Highlights, respectively.

Sub-Transfer Agent Fees. The Transfer Agent has retained Shareholder Services, Inc., a wholly-owned subsidiary of OFI (the “Sub-Transfer Agent”), to provide the day-to-day transfer agent and shareholder servicing of the Fund. Under the Sub-Transfer Agency Agreement, the Transfer Agent pays the Sub-Transfer Agent an annual fee in monthly installments, equal to a

NOTES TO FINANCIAL STATEMENTS Continued

8. Fees and Other Transactions with Affiliates (Continued)

percentage of the transfer agent fee collected by the Transfer Agent from the Fund, which shall be calculated after any applicable fee waivers. The fee paid to the Sub-Transfer Agent is paid by the Transfer Agent, not by the Fund.

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 reporting period, the Fund’s projected benefit obligations, payments to retired Trustees and accumulated liability were as follows:

Projected Benefit Obligations Increased	$	—
Payments Made to Retired Trustees		120
Accumulated Liability as of March 31, 2016		826

The Fund’s Board of Trustees (“Board”) 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 with the compensation deferral plan.

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 pursuant to Rule 12b-1 under the 1940 Act. 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

8. Fees and Other Transactions with Affiliates (Continued)

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 pursuant to Rule 12b-1 under the 1940 Act to compensate the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. 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 Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets. The Plans continue in effect from year to year only if the Fund’s Board of Trustees votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

Sales Charges. Front-end sales charges and 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
	Class A		Contingent		Contingent		Contingent

Year Ended	Distributor		Distributor		Distributor		Distributor
March 31, 2016		$14,537		$1,962		$1,524		$1,236

Waivers and Reimbursements of Expenses. The Manager has contractually 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 interest and fees from borrowings and interest and related expenses from inverse floaters, would not exceed 0.80% of average annual net assets for Class A shares, 1.55% of average annual net assets for both Class B and Class C shares and 0.80% of average annual net assets for Class Y shares. During the reporting period, the Manager reimbursed $79,007, $4,122, $35,973 and $592 for Class A, Class B, Class C and Class Y shares, respectively.

Waivers and/or reimbursements may be modified or terminated as set forth according to the terms in the prospectus.

Cross-Trades. The Fund is permitted to purchase and sell securities (“cross-trade”) from and to other Funds managed by the Manager (“cross-trade”) pursuant to “Cross-Trading” Procedures adopted by the Fund’s Board of Trustees. These procedures are designed to ensure that any cross-trade of securities by the Fund from or to another fund that is or could be considered an affiliate of the Fund under certain limited circumstances by virtue of having a common investment adviser, common Officer, or common Trustee complies with Rule 17a-7 of

51      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

8. Fees and Other Transactions with Affiliates (Continued)

the 1940 Act. Further, as defined under these procedures, each cross-trade is effected at the current market price.

During the reporting period, the Fund had $3,882,756 in sales considered cross-trades, resulting in $119,474 of realized gain/(loss).

9. Borrowings and Other Financing

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 (meaning that the value of those assets must be at least 300% of the amount borrowed). The Fund can use those borrowings for investment-related purposes such as purchasing portfolio securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. When the Fund invests borrowed money in portfolio securities, it is using a speculative investment technique known as leverage and changes in the value of the Fund’s investments will have a larger effect on its share price than if it did not borrow because of the effect of leverage.

The Fund can also use the borrowings for other investment-related purposes, including in connection with the Fund’s inverse floater investments as discussed in Note 4. The Fund may use the borrowings to reduce the leverage amount of, or unwind or “collapse” trusts that issued “inverse floaters” owned by the Fund, or in circumstances in which the Fund has entered into a shortfall and forbearance agreement with the sponsor of the inverse floater trust to meet the Fund’s obligation to reimburse the sponsor of the inverse floater for the difference between the liquidation value of the underlying bond and the amount due to holders of the short-term floating rate notes issued by the Trust. See the discussion in Note 4 (Inverse Floating Rate Securities) for additional information.

The Fund will pay interest and may pay other fees in connection with loans. If the Fund does borrow, it will be subject to greater expenses than funds that do not borrow. The interest on borrowed money and the other fees incurred in conjunction with loans are an expense that might reduce the Fund’s yield and return. 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 Citibank N.A. which enables it to participate with certain other Oppenheimer funds in a committed, secured borrowing facility that permits borrowings of up to $2.5 billion, collectively, by the Oppenheimer Rochester Funds. 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 (0.5875 % at period end). The Fund pays additional fees monthly to its lender on its outstanding borrowings to manage and administer the facility and is 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

52      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

9. Borrowings and Other Financing (Continued)

Fund’s Statement of Operations related to its participation in the borrowing facility during the reporting period equal 1.05% 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.

At period end, the Fund had borrowings outstanding at an interest rate of 0.5875%.

Details of the borrowings for the reporting period are as follows:

Average Daily Loan Balance	$	4,814,208
Average Daily Interest Rate		0.316 %
Fees Paid	$	333,015
Interest Paid	$	12,888

Reverse Repurchase Agreements. The Fund may engage in reverse repurchase agreements. A reverse repurchase agreement is the sale of one or more securities to a counterparty at an agreed-upon purchase price with the simultaneous agreement to repurchase those securities on a future date at a higher repurchase price. The repurchase price represents the repayment of the purchase price and interest accrued thereon over the term of the repurchase agreement. The cash received by the Fund in connection with a reverse repurchase agreement may be used for investment-related purposes such as purchasing portfolio securities or for other purposes such as those described in the preceding “Borrowings” note.

The Fund entered into a Committed Repurchase Transaction Facility (the “Facility”) with J.P. Morgan Securities LLC (the “counterparty”) which enables it to participate with certain other Oppenheimer funds in a committed reverse repurchase agreement facility that permits aggregate outstanding reverse repurchase agreements of up to $750 million, collectively. Interest is charged to the Fund on the purchase price of outstanding reverse repurchase agreements at current LIBOR rates plus an applicable spread. The Fund is also allocated its pro-rata share of an annual structuring fee based on the total Facility size and ongoing commitment fees based on the total unused amount of the Facility. The Fund retains the economic exposure to fluctuations in the value of securities subject to reverse repurchase agreements under the Facility and therefore these transactions are considered secured borrowings for financial reporting purposes. The Fund also continues to receive the economic benefit of interest payments received on securities subject to reverse repurchase agreements, in the form of a direct payment from the counterparty. These payments are included in interest income on the Statement of Operations. Total fees and interest related to the Fund’s participation in the Facility during the reporting period are included in expenses on the Fund’s Statement of Operations and equal 0.28% of the Fund’s average net assets on an annualized basis.

The securities subject to reverse repurchase agreements under the Facility are valued on a daily basis. To the extent this value, after adjusting for certain margin requirements of the Facility, exceeds the cash proceeds received, the Fund may request the counterparty to return securities equal in margin value to this excess. To the extent that the cash proceeds

53      OPPENHEIMER ROCHESTER ARIZONA MUNICIPAL FUND

NOTES TO FINANCIAL STATEMENTS Continued

9. Borrowings and Other Financing (Continued)

received exceed the margin value of the securities subject to the transaction, the counterparty may request additional securities from the Fund. The Fund has the right to declare each Wednesday as the repurchase date for any outstanding reverse repurchase agreement upon delivery of advanced notification and may also recall any security subject to such a transaction by substituting eligible securities of equal or greater margin value according to the Facility’s terms.

At period end, the Fund had no outstanding reverse repurchase agreements.

Details of reverse repurchase agreement transactions for the reporting period are as follows:

Fees Paid $                                          159,946

10. Pending Litigation

In 2009, several putative class action lawsuits were filed and later consolidated before the U.S. District Court for the District of Colorado against OppenheimerFunds, Inc. (“OFI”), OppenheimerFunds Distributor, Inc. (“OFDI”), and Oppenheimer Rochester California Municipal Fund, a fund advised by OFI Global Asset Management, Inc. and distributed by the Distributor (the “California Fund”), in connection with the California Fund’s investment performance. The plaintiffs asserted claims against OFI, OFDI and certain present and former trustees and officers of the California Fund under the federal securities laws, alleging, among other things, that the disclosure documents of the California Fund contained misrepresentations and omissions and the investment policies of the California Fund were not followed. Plaintiffs in the suit filed an amended complaint and defendants filed a motion to dismiss. In 2011, the court issued an order which granted in part and denied in part the defendants’ motion to dismiss. In 2012, plaintiffs filed a motion, which defendants opposed, to certify a class and appoint class representatives and class counsel. In March 2015, the court granted plaintiffs’ motion for class certification. In May 2015, the U.S. Court of Appeals for the Tenth Circuit vacated the class certification order and remanded the matter to the district court for further proceedings. In October 2015, the district court reaffirmed its order and determined that the suit will proceed as a class action. In December 2015, the Tenth Circuit denied defendants’ petition to appeal the district court’s reaffirmed class certification order.

OFI and OFDI believe the suit is without merit; that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them in the suit; and that no estimate can yet be made as to the amount or range of any potential loss. Furthermore, OFI believes that the suit should not impair the ability of OFI or OFDI to perform their respective duties to the Fund and that the outcome of the suit 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 Arizona Municipal Fund:

We have audited the accompanying statement of assets and liabilities of Oppenheimer Rochester Arizona Municipal Fund, including the statement of investments, as of March 31, 2016, and the related statement of operations and cash flows for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2016, by correspondence with the custodian 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 Arizona Municipal Fund as of March 31, 2016, 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 five-year period then ended, in conformity with U.S. generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION Unaudited

In early 2016, if applicable, shareholders of record received information regarding all dividends and distributions paid to them by the Fund during calendar year 2015.

None of the dividends paid by the Fund during the reporting period are eligible for the corporate dividend-received deduction. 98.43% of the dividends were derived from interest on municipal bonds and are not subject to federal income taxes. To the extent a shareholder is subject to any state or local tax laws, some or all of the dividends received may be taxable.

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

Householding—Delivery of Shareholder Documents

This is to inform you about OppenheimerFunds’ “householding” policy. If more than one member of your household maintains an account in a particular fund, OppenheimerFunds will mail only one copy of the fund’s prospectus (or, if available, the fund’s summary prospectus), annual and semiannual report and privacy policy. The consolidation of these mailings, called householding, benefits your fund through reduced mailing expense, and benefits you by reducing the volume of mail you receive from OppenheimerFunds. Householding does not affect the delivery of your account statements.

  Please note that we will continue to household these mailings for as long as you remain an OppenheimerFunds shareholder, unless you request otherwise. If you prefer to receive multiple copies of these materials, please call us at 1.800.CALL-OPP (225-5677). You may also notify us in writing or via email. We will begin sending you individual copies of the prospectus (or, if available, the summary prospectus), reports and privacy policy within 30 days of receiving your request to stop householding.

Internet Security and Encryption

In general, the email services provided by our website are encrypted and provide a secure and private means of communication with us. To protect your own privacy, confidential and/or personal information should only be communicated via email when you are advised that you are using a secure website. As a security measure, we do not include personal or account information in non-secure emails, and we advise you not to send such information to us in non-secure emails. Instead, you may take advantage of the secure features of our website to encrypt your email correspondence. To do this, you will need to use a browser that supports Secure Sockets Layer (SSL) protocol.

We do not guarantee or warrant that any part of our website, including files available for download, are free of viruses or other harmful code. It is your responsibility to take appropriate precautions, such as use of an anti-virus software package, to protect your computer hardware and software.

● All transactions, including redemptions, exchanges and purchases, are secured by SSL and 256-bit encryption. SSL is used to establish a secure connection between your PC and OppenheimerFunds’ server. It transmits information in an encrypted and scrambled format.

● Encryption is achieved through an electronic scrambling technology that uses a “key” to code and then decode the data. Encryption acts like the cable converter box you may have on your television set. It scrambles data with a secret code so that no one can make sense of it while it is being transmitted. When the data reaches its destination, the same software unscrambles the data.

● You can exit the secure area by either closing your browser, or for added security, you can use the Log Out button before you close your browser.

Other Security Measures

We maintain physical, electronic and procedural safeguards to protect your personal account information. Our employees and agents have access to that information only so that they may offer you products or provide services, for example, when responding to your account questions.
