Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a return of 0.20% during the reporting period, outperforming the -1.08% return provided by the Bloomberg Barclays U.S. Aggregate Bond Index (the “Index”).

MARKET OVERVIEW

Markets continued to rally to close 2017. However, volatility reemerged during the first quarter of 2018. U.S. Treasury yields rose during the reporting period, flattening the yield curve and pricing in over two interest rate hikes by the Federal Reserve (the Fed) for 2018. Credit spreads were tighter across most sectors, fully absorbing the rise in rates and finishing the reporting period with positive returns. Despite the rise in short-term rates, the U.S. dollar (USD) weakened against most currencies in developed and emerging markets.

Global economic data stabilized during the reporting period. The cyclical uptick has been encouraging with improvements in global investment, trade, and industrial production. Business and consumer confidence are at cyclical highs in many countries at the end of the period. A major change in the outlook was a result of the fiscal stimulus in the U.S., comprising both tax cuts and spending promises. In our view, this stimulus could add to growth over the next two years. First quarter 2018 Eurozone data have cooled slightly, but after several quarters of upside surprises, some stabilization is not surprising. The underlying drivers of Eurozone growth are intact and we believe growth should remain

around its current trend. Growth expectations remain upbeat with certain countries, like Canada, exceeding expectations. Latin America (LatAm) is a different story with growth being more challenged overall with the exception of Brazil. LatAm also faces a number of political challenges over the course of the year with elections in several countries and NAFTA negotiations.

The U.S. economy continued to perform well. On the inflation front, the negative surprise of the past year is behind us, and underlying inflation is converging toward the Fed’s 2% target. The Fed is on track to hike rates 3-4 times this year, with the first delivered this March. During the reporting period, Chairman Jay Powell was installed as the new head of the Federal Reserve, taking over from Janet Yellen. Under his leadership, the Federal Open Market Committee (FOMC) signaled that the Fed will remain cautious and will continue on a similar policy rate path.

FUND REVIEW

For the six-month reporting period, the Fund’s strongest absolute results stemmed from its exposure to emerging markets local rates (government bonds) and senior floating rate loans.

3       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

Emerging market local debt performed well this reporting period. A new theme emerged in the first quarter of 2018; markets are pricing in a pause or, in some cases, the end of a monetary policy easing. This resulted in curves steepening from India and Russia to Brazil and Hungary, which we find more appealing than flatter yield curves. Flatter yield curves provide investors with fewer incentives to purchase longer-maturity bonds and typically reflect expectations of rising interest rates. We saw curves as steep as at they were in 2013. In the meantime, valuations remain attractive in our view as real yields in the belly of the curve are appealing from a risk / return vantage point. During the reporting period we tapped this premium by increasing the duration of our locally denominated bond holdings in some markets.

Solid economic fundamentals and positive earnings growth lead us to continue to like spread sectors, though we have reduced our exposure recently based on valuations and have rotated away from some of the higher beta sectors. We like senior floating rate loans for similar reasons. In addition, we believe loans should outperform other credit sectors should the Fed hike rates at a more aggressive pace than the market expects. During the reporting period, this positioning paid off and senior floating rate loans were additive to performance.

The most significant detractor from the Fund’s performance was its exposure to mortgages. As interest rate volatility increased during the

reporting period, mortgages underperformed U.S. Treasuries.

STRATEGY & OUTLOOK

The current outlook for the global economy continues to be positive with synchronized global growth close to 3.5%. U.S. growth projections are being upgraded higher and world economic momentum seems to be stabilizing. We continue to expect 2018 to be a “risk-friendly” environment, but there are several global geopolitical and policy challenges. Credit fundamentals, outside of some distressed sectors like retail and fixed line telecom, continue to improve modestly due to earnings growth and a lack of capital expenditure. Higher commodity prices, driven by rising demand, even in oil, have had a positive effect especially on high yield and emerging market credits. Given our expectation that growth will stabilize around current levels, our outlook remains positive.

In our view, one potential headwind to prospective returns are valuations that are rich relative to historical levels, leaving little cushion for potential negative shocks. That valuations appear somewhat rich at this point in the cycle is not unusual, especially when growth is positive and fundamentals are improving. Chairman Powell is expected to continue former Chairwoman Yellen’s gradual approach to normalization.

Despite solid economic fundamentals and positive earnings growth, we continue to reduce exposure to spread sectors. We are

4       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

reducing some exposure to U.S. high-grade and have modestly increased exposure to emerging market local currency sovereign debt (on a hedged basis). We are also modifying the duration composition of the Fund to the front-end of the U.S. yield curve. Internationally, we expect strong performance from emerging market local bonds over the next few months as the growth differential continues to favor emerging market assets. From a valuation perspective, real yields remain at high enough levels to absorb further modest monetary tightening in developed markets.

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 investment. 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 shares, the contingent deferred sales charge of 1% for the 1-year period. There is no sales charge for Class I, Class R and 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

8       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

conversion. Returns for periods of less than one year are cumulative and not annualized. See Fund prospectuses and summary prospectuses for more information on share classes and sales charges.

Standardized yield is based on an SEC-standardized formula designed to approximate the Fund’s annualized hypothetical current income from securities less expenses for the 30-day period ended March 31, 2018 and that date’s maximum offering price (for Class A shares) or net asset value (for all other share classes). Each result is compounded semiannually and then annualized. Falling share prices will tend to artificially raise yields. The unsubsidized standardized yield is computed under an SEC-standardized formula based on net income earned for the 30-day period ended March 31, 2018. The calculation excludes any expense reimbursements and thus may result in a lower yield.

The Fund’s performance is compared to the performance of the Bloomberg Barclays U.S. Aggregate Bond Index, an index of U.S dollar-denominated, investment-grade U.S. corporate government and mortgage-backed securities. The Index is unmanaged and cannot be purchased directly 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.

The views in the Fund Performance Discussion represent the opinions of this Fund’s portfolio managers and are not intended as investment advice or to predict or depict the performance of any investment. These views are as of the close of business on March 31, 2018, and are subject to change based on subsequent developments. The Fund’s portfolio and strategies are subject to change.

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, 2018.

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, 2018” 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 R	1,000.00	1,018.75	6.26
Class Y	1,000.00	1,021.19	3.79

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 182/365 (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, 2018 are as follows:

Class	Expense Ratios
Class A		0.99	%
Class B		1.79
Class C		1.75
Class I		0.59
Class R		1.24
Class Y		0.75

The expense ratios reflect voluntary and/or contractual waivers and/or reimbursements of expenses by the Fund’s Manager and Transfer Agent. Some of these undertakings may be modified or terminated at any time, as indicated in the Fund’s prospectus. The “Consolidated 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. Represents securities sold under Rule 144A, which are exempt from registration under the Securities Act of 1933, as amended. These securities have been determined to be liquid under guidelines established by the Board of Trustees. These securities amount to $1,169,939,711 or 27.88% of the Fund’s net assets at period end.

2. Represents the current interest rate for a variable or increasing rate security, determined as [Referenced Rate + Basis-point spread].

3. Interest-Only Strips represent the right to receive the monthly interest payments on an underlying pool of mortgage loans. These securities typically decline in price as interest rates decline. Most other fixed income securities increase in price when interest rates decline. The principal amount of the underlying pool represents the notional amount on which current interest is calculated. The price of these securities is typically more sensitive to changes in prepayment rates than traditional mortgage-backed securities (for example, GNMA pass-throughs). Interest rates disclosed represent current yields based upon the current cost basis and estimated timing and amount of future cash flows. These securities amount to $11,235,735 or 0.27% of the Fund’s net assets at period end.

4. Interest rate is less than 0.0005%.

1. Organization

Oppenheimer Global Strategic Income 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 total return. 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.

The Fund offers Class A, Class C, Class I, Class R 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 and Class R 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 R shares are sold only through retirement plans. Retirement plans that offer Class R shares may impose charges on those accounts. Class I and 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 I and 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, C and R shares have separate distribution and/or service plans under which they pay fees. Class I and 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.

Basis for Consolidation. The Fund has established a Cayman Islands exempted company, Oppenheimer Global Strategic Income Fund (Cayman) Ltd., which is wholly-owned and controlled by the Fund (the “Subsidiary”). The Fund and Subsidiary are both managed by the Manager. The Fund may invest up to 25% of its total assets in the Subsidiary. The Subsidiary invests primarily in Regulation S securities. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary.

The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated. At

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

2. Significant Accounting Policies (Continued)

period end, the Fund owned 155,194 shares with net assets of $13,507,150 in the Subsidiary.

Other financial information at period end:

Total market value of investments	$	1,489,216
Net assets	$	13,507,150
Net income (loss)	$	(25,981)
Net realized gain (loss)	$	180,658
Net change in unrealized appreciation/depreciation	$	(208,344)

Foreign Currency Translation. The books and records of the Fund are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis: (1) Value of investment securities, other assets and liabilities — at the exchange rates prevailing at market close as described in Note 3.

(2) Purchases and sales of investment securities, income and expenses — at the rates of exchange prevailing on the respective dates of such transactions.

Although the net assets and the values are presented at the foreign exchange rates at market close, the Fund does not isolate the portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in prices of securities held. Such fluctuations are included with the net realized and unrealized gains or losses from investments shown in the Consolidated Statement of Operations.

For securities, which are subject to foreign withholding tax upon disposition, realized and unrealized gains or losses on such securities are recorded net of foreign withholding tax.

Reported net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, the difference between the amounts of dividends, interest, and foreign withholding tax reclaims recorded on the Fund’s books, and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities other than investments in securities, resulting from changes in the exchange rate.

Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

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 or at other times as determined necessary by the Manager.

The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made to shareholders prior to the Fund’s fiscal year end

96       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

2. Significant Accounting Policies (Continued)

may ultimately be categorized as a tax return of capital.

Investment Income. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. Non-cash dividends included in dividend income, if any, are recorded at the fair value of the securities received. Withholding taxes on foreign dividends, if any, and capital gains taxes on foreign investments, if any, have been provided for in accordance with the Fund’s understanding of the applicable tax rules and regulations. Interest income, if any, is recognized on an accrual basis. Discount and premium, which are included in interest income on the Consolidated Statement of Operations, are amortized or accreted daily.

Return of Capital Estimates. Distributions received from the Fund’s investments in Master Limited Partnerships (MLPs), generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded.

Custodian Fees. “Custodian fees and expenses” in the Consolidated Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Fund, at a rate equal to the Federal Funds Rate plus 2.00%. The “Reduction to custodian expenses” line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings.

Security Transactions. Security transactions are recorded on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost.

Indemnifications. The Fund’s organizational documents provide current and former Trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

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 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

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

2. Significant Accounting Policies (Continued)

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 September 30, 2017, including open tax years, and does not believe there are any uncertain tax positions requiring recognition in the Fund’s financial statements.

Subchapter M requires, among other things, that at least 90% of the Fund’s gross income be derived from securities or derived with respect to its business of investing in securities (typically referred to as “qualifying income”). Income from commodity-linked derivatives may not be treated as “qualifying income” for purposes of the 90% gross income requirement. The Internal Revenue Service (IRS) has previously issued a number of private letter rulings which conclude that income derived from commodity index-linked notes and investments in a wholly-owned subsidiary will be “qualifying income.” As a result, the Fund will gain exposure to commodities through commodity-linked notes and its wholly-owned subsidiary.

The IRS has suspended the granting of private letter rulings pending further review. As a result, there can be no assurance that the IRS will not change its position with respect to commodity-linked notes and wholly-owned subsidiaries. In addition, future legislation and guidance from the Treasury and the IRS may adversely affect the Fund’s ability to gain exposure to commodities through commodity-linked notes and its wholly-owned subsidiary.

The Fund is required to include in income for federal income tax purposes all of the subsidiary’s net income and gains whether or not such income is distributed by the subsidiary. Net income and gains from the subsidiary are generally treated as ordinary income by the Fund, regardless of the character of the subsidiary’s underlying income. Net losses from the subsidiary do not pass through to the Fund for federal income tax purposes.

During the fiscal year ended September 30, 2017, the Fund did not utilize any capital loss carryforwards to offset capital gains realized in that fiscal year. The Fund had post-October foreign currency losses of $2,974,415, which were deferred. Details of the fiscal year ended September 30, 2017 capital loss carryforwards are included in the table below. Capital loss carryforwards with no expiration, if any, must be utilized prior to those with expiration dates. Capital losses with no expiration will be carried forward to future years if not offset by gains.

Expiring
2018	$	240,345,967
No expiration		649,542,117
Total	$	889,888,084

At period end, it is estimated that the capital loss carryforwards would be $240,345,967 expiring by 2018 and $676,122,462, which will not expire. The estimated capital loss carryforward represents the carryforward as of the end of the last fiscal year, increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. During the reporting period, it is estimated that the Fund will not utilize any capital loss carryforward to offset realized capital gains.

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

98       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

2. Significant Accounting Policies (Continued)

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.

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	$	4,581,367,546
Federal tax cost of other investments		(378,751,909)
Total federal tax cost	$	4,202,615,637
Gross unrealized appreciation	$	105,652,518
Gross unrealized depreciation		(156,181,532)
Net unrealized depreciation	$	(50,529,014)

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 4:00 P.M. Eastern Time, on each day the New York Stock Exchange (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 least quarterly or more frequently, if necessary.

Valuation Methods and Inputs

Securities are valued primarily using unadjusted quoted market prices, when available, as supplied by third party pricing services or broker-dealers.

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

99       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

3. Securities Valuation (Continued)

Equity securities traded on a securities exchange (including exchange-traded derivatives other than futures and futures options) are valued based on the official closing price on the principal exchange on which the security is traded, as identified by the Manager, prior to the time when the Fund’s assets are valued. If the official closing price is unavailable, the security is valued at the last sale price on the principal exchange on which it is traded, or if no sales occurred, the security is valued at the mean between the quoted bid and asked prices. Over-the-counter equity securities are valued at the last published sale price, or if no sales occurred, at the mean between the quoted bid and asked prices. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the time when the Fund’s assets are valued.

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, short-term notes, 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. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, sometimes at lower prices than institutional round lot trades. Standard inputs generally considered by third-party pricing vendors include reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, as well as other appropriate factors.

Loans are valued at the mean between the bid and asked prices utilizing evaluated prices obtained from third party pricing services or broker-dealers. Standard inputs generally considered by third-party pricing vendors include information obtained from market participants regarding broker-dealer price quotations.

Structured securities, swaps, swaptions, and other over-the-counter derivatives are valued utilizing evaluated prices obtained from third party pricing services or broker-dealers. Standard inputs generally considered by third-party pricing vendors include market information relevant to the underlying reference asset such as the price of financial instruments, stock market indices, foreign currencies, interest rate spreads, commodities, credit spreads, credit event probabilities, index values, individual security values, forward interest rates, variable interest rates, volatility measures, and forward currency rates, or the occurrence of other specific events.

Forward foreign currency exchange contracts are valued utilizing current and forward currency rates obtained from third party pricing services. When the settlement date of a contract is an interim date for which a quotation is not available, interpolated values are derived using the nearest dated forward currency rate.

Futures contracts and futures options traded on a commodities or futures exchange will be valued at the final settlement price or official closing price on the principal exchange as reported by such principal exchange at its trading session ending at, or most recently prior to, the time when the Fund’s assets are valued.

100       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

3. Securities Valuation (Continued)

Securities for which market quotations are not readily available, or when a significant event has occurred that would materially affect the value of the security, are 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. Those standardized fair valuation 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 regularly compares prior day prices 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 on the significance and source of the inputs to its valuation. Various data inputs may be 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.

3. Securities Valuation (Continued)

The Fund classifies each of its investments in investment companies which are publicly offered as Level 1. Investment companies that are not publicly offered, if any, are classified as Level 2 in the fair value hierarchy.

4. Investments and Risks

Risks of Foreign Investing. The Fund may invest in foreign securities which are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to limited or no regulatory oversight.

Investments in Affiliated Funds. The Fund is permitted to invest in other mutual funds advised by the Manager (“Affiliated Funds”). Affiliated Funds are open-end management investment companies registered under the 1940 Act, as amended. The Manager is the investment adviser of, and the Sub-Adviser provides investment and related advisory services to, the Affiliated Funds. When applicable, the Fund’s investments in Affiliated Funds are included in the Consolidated Statement of Investments. Shares of Affiliated Funds are valued at their net asset value per share. As a shareholder, the Fund is subject to its proportional share of the Affiliated Funds’ expenses, including their management fee. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in the Affiliated Funds.

103       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

4. Investments and Risks (Continued)

Each of the Affiliated Funds in which the Fund invests has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Affiliated Fund than in another, the Fund will have greater exposure to the risks of that Affiliated Fund.

Investments in Money Market Instruments. The Fund is permitted to invest its free cash balances in money market instruments to provide liquidity or for defensive purposes. The Fund may invest in money market instruments by investing in Class E shares of Oppenheimer Institutional Government Money Market Fund (“IGMMF”), which is an Affiliated Fund. IGMMF is regulated as a money market fund under the 1940 Act, as amended. The Fund may also invest in money market instruments directly or in other affiliated or unaffiliated money market funds.

Investment in Oppenheimer Master Funds. The Fund is permitted to invest in entities sponsored and/or advised by the Manager or an affiliate. Certain of these entities in which the Fund invests are mutual funds registered under the 1940 Act, as amended, that expect to be treated as partnerships for tax purposes, specifically Oppenheimer Master Loan Fund, LLC (“Master Loan”) and Oppenheimer Master Event-Linked Bond Fund, LLC (“Master Event-Linked Bond”) (the “Master Funds”). Each Master Fund has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Master Fund than in another, the Fund will have greater exposure to the risks of that Master Fund.

The investment objective of Master Loan is to seek income. The investment objective of Master Event-Linked Bond is to seek total return. The Fund’s investments in the Master Funds are included in the Consolidated Statement of Investments. The Fund recognizes income and gain/(loss) on its investments in each Master Fund according to its allocated pro-rata share, based on its relative proportion of total outstanding Master Fund shares held, of the total net income earned and the net gain/(loss) realized on investments sold by the Master Funds. As a shareholder, the Fund is subject to its proportional share of the Master Funds’ expenses, including their management fee. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in the Master Funds. The Fund owns 42.5% of Master Loan and 27.8% of Master Event-Linked Bond at period end.

Master Limited Partnerships (“MLPs”). MLPs issue common units that represent an equity ownership interest in a partnership and provide limited voting rights. MLP common units are registered with the Securities and Exchange Commission (“SEC”), and are freely tradable on securities exchanges such as the NYSE and the NASDAQ Stock Market (“NASDAQ”), or in the over-the-counter (“OTC”) market. An MLP consists of one or more general partners, who conduct the business, and one or more limited partners, who contribute capital. MLP common unit holders have a limited role in the partnership’s operations and management. The Fund, as a limited partner, normally would not be liable for the debts of the

104       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

4. Investments and Risks (Continued)

MLP beyond the amounts the Fund has contributed, but would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances creditors of an MLP would have the right to seek return of capital distributed to a limited partner. This right of an MLP’s creditors would continue after the Fund sold its investment in the MLP.

Structured Securities. The Fund invests in structured securities whose market values, interest rates and/or redemption prices are linked to the performance of underlying foreign currencies, interest rate spreads, stock market indices, prices of individual securities, commodities or other financial instruments or the occurrence of other specific events. The structured securities are often leveraged, increasing the volatility of each note’s market value relative to the change in the underlying linked financial element or event. Fluctuations in value of these securities are recorded as unrealized gains and losses in the accompanying Consolidated Statement of Operations. The Fund records a realized gain or loss when a structured security is sold or matures.

Loans. The Fund invests in loans made to U.S. and foreign borrowers that are corporations, partnerships or other business entities. The Fund will do so directly as an original lender or by assignment or indirectly through participation agreements or certain derivative instruments. While many of these loans will be collateralized, the Fund can also invest in uncollateralized loans. Loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancing of borrowers. The loans often pay interest at rates that float above (or are adjusted periodically based on) a benchmark that reflects current interest rates although the Fund can also invest in loans with fixed interest rates.

When investing in loans, the Fund generally will have a contractual relationship only with the lender, not with the relevant borrower. As a result, the Fund generally will have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the relevant borrower. The Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, the Fund will assume the credit risk of both the borrower and the institution selling the participation to the Fund.

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

105       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

4. Investments and Risks (Continued)

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 purchased securities issued on a when-issued or delayed delivery basis and sold securities issued on a delayed delivery basis as follows:

	When-Issued or Delayed Delivery Basis Transactions
Purchased securities		$555,371,823
Sold securities		93,648,065

The Fund may enter into “forward roll” transactions with respect to mortgage-related securities. In this type of transaction, the Fund sells a mortgage-related security to a buyer and simultaneously agrees to repurchase a similar security (same type, coupon and maturity) at a later date at a set price. During the period between the sale and the repurchase, the Fund will not be entitled to receive interest and principal payments on the securities that have been sold. The Fund records the incremental difference between the forward purchase and sale of each forward roll as realized gain (loss) on investments or as fee income in the case of such transactions that have an associated fee in lieu of a difference in the forward purchase and sale price.

Forward roll transactions may be deemed to entail embedded leverage since the Fund purchases mortgage-related securities with extended settlement dates rather than paying for the securities under a normal settlement cycle. This embedded leverage increases the Fund’s market value of investments relative to its net assets which can incrementally increase the volatility of the Fund’s performance. Forward roll transactions can be replicated over multiple settlement periods.

Risks of entering into forward roll transactions include the potential inability of the counterparty to meet the terms of the agreement; the potential of the Fund to receive inferior securities at redelivery as compared to the securities sold to the counterparty; and counterparty credit risk.

At period end, the counterparty pledged $809,809 of collateral to the Fund for forward roll transactions.

At period end, the Fund pledged $516,000 of collateral to the counterparty for forward roll transactions.

Restricted Securities. At period end, investments in securities included issues that are restricted. A restricted security may have a contractual restriction on its resale and is valued under methods approved by the Board of Trustees as reflecting fair value. Securities that are restricted are marked with an applicable footnote on the Consolidated Statement of Investments. Restricted securities are reported on a schedule following the Consolidated

106       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

4. Investments and Risks (Continued)

Statement of Investments.

Equity Security Risk. Stocks and other equity securities fluctuate in price. The value of the Fund’s portfolio may be affected by changes in the equity markets generally. Equity markets may experience significant short-term volatility and may fall sharply at times. Different markets may behave differently from each other and U.S. equity markets may move in the opposite direction from one or more foreign stock markets. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments.

The prices of individual equity securities generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company’s securities. These factors may include, but are not limited to, poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry.

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 and/or principal payment.

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

Cost	$23,446,483
Market Value	$2,310,418
Market Value as % of Net Assets	0.06%

Sovereign Debt Risk. The Fund invests in sovereign debt securities, which are subject to certain special risks. These risks include, but are not limited to, the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay the principal on its sovereign debt. There may also be no legal process for collecting sovereign debt that a government does not pay or bankruptcy proceedings through which all or part of such sovereign debt may be collected. In addition, a restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, reduced liquidity and increased volatility, among others.

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

107       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

5. Market Risk Factors (Continued)

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 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. Use of Derivatives

The Fund’s investment objective not only permits the Fund to purchase investment securities, it also allows the Fund to enter into various types of derivatives contracts, including, but not limited to, futures contracts, forward currency exchange contracts, credit default swaps, interest rate swaps, total return swaps, variance swaps and purchased and written options. In doing so, the Fund will employ strategies in differing combinations to permit it to increase, decrease, or change the level or types of exposure to market risk factors. These instruments may allow the Fund to pursue its objectives more quickly and efficiently than if it were to make direct purchases or sales of securities capable of effecting a similar response to market factors. Such contracts may be entered into through a bilateral over-the-counter (“OTC”) transaction, or through a securities or futures exchange and cleared through a clearinghouse.

Derivatives may have little or no initial cash investment relative to their market value exposure and therefore can produce significant gains or losses in excess of their cost due to changes in the market risk factors and the overall market. This use of embedded leverage allows the Fund to increase its market value exposure relative to its net assets and can substantially increase the volatility of the Fund’s performance. In instances where the Fund is using derivatives to decrease, or hedge, exposures to market risk factors for securities held by the Fund, there are also risks that those derivatives may not perform as expected resulting in

108       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

6. Use of Derivatives (Continued)

losses for the combined or hedged positions. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment.

Additional associated risks from investing in derivatives also exist and potentially could have significant effects on the valuation of the derivative and the Fund. Typically, the associated risks are not the risks that the Fund is attempting to increase or decrease exposure to, per its investment objectives, but are the additional risks from investing in derivatives. Examples of these associated risks are liquidity risk, which is the risk that the Fund will not be able to sell the derivative in the open market in a timely manner, and counterparty credit risk, which is the risk that the counterparty will not fulfill its obligation to the Fund.

The Fund’s actual exposures to these market risk factors and associated risks during the period are discussed in further detail, by derivative type, below.

Forward Currency Exchange Contracts

The Fund may enter into forward currency exchange contracts (“forward contracts”) for the purchase or sale of a foreign currency at a negotiated rate at a future date. Such contracts are traded in the OTC inter-bank currency dealer market.

Forward contracts are reported on a schedule following the Consolidated Statement of Investments. The unrealized appreciation (depreciation) is reported in the Consolidated Statement of Assets and Liabilities as a receivable (or payable) and in the Consolidated Statement of Operations within the change in unrealized appreciation (depreciation). At contract close, the difference between the original cost of the contract and the value at the close date is recorded as a realized gain (loss) in the Consolidated Statement of Operations.

The Fund may enter into forward foreign currency exchange contracts in order to decrease exposure to foreign exchange rate risk associated with either specific transactions or portfolio instruments or to increase exposure to foreign exchange rate risk.

During the reporting period, the Fund had daily average contract amounts on forward contracts to buy and sell of $929,992,128 and $1,047,401,856, respectively.

Additional associated risk to the Fund includes counterparty credit risk. Counterparty credit risk arises from the possibility that the counterparty to a forward contract will default and fail to perform its obligations to the Fund.

Futures Contracts

A futures contract is a commitment to buy or sell a specific amount of a commodity, financial instrument or currency at a negotiated price on a stipulated future date. The Fund may buy and sell futures contracts and may also buy or write put or call options on these futures contracts. Futures contracts and options thereon are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange.

Upon entering into a futures contract, the Fund is required to deposit either cash or securities (initial margin) in an amount equal to a certain percentage of the contract value in an account registered in the futures commission merchant’s name. Subsequent payments (variation margin) are paid to or from the futures commission merchant each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains

109       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

6. Use of Derivatives (Continued)

and losses. Should the Fund fail to make requested variation margin payments, the futures commission merchant can gain access to the initial margin to satisfy the Fund’s payment obligations.

Futures contracts are reported on a schedule following the Consolidated Statement of Investments. Securities held by a futures commission merchant to cover initial margin requirements on open futures contracts are noted in the Consolidated Statement of Investments. Cash held by a futures commission merchant to cover initial margin requirements on open futures contracts and the receivable and/or payable for the daily mark to market for the variation margin are noted in the Consolidated Statement of Assets and Liabilities. The net change in unrealized appreciation and depreciation is reported in the Consolidated Statement of Operations. Realized gains (losses) are reported in the Consolidated Statement of Operations at the closing or expiration of futures contracts.

The Fund may purchase and/or sell financial futures contracts and options on futures contracts to gain exposure to, or decrease exposure to interest rate risk, equity risk, foreign exchange rate risk, volatility risk, or commodity risk.

During the reporting period, the Fund had an ending monthly average market value of $468,276,005 and $489,469,448 on futures contracts purchased and sold, respectively.

Additional associated risks of entering into futures contracts (and related options) include the possibility that there may be an illiquid market where the Fund is unable to liquidate the contract or enter into an offsetting position and, if used for hedging purposes, the risk that the price of the contract will correlate imperfectly with the prices of the Fund’s securities.

Option Activity

The Fund may buy and sell put and call options, or write put and call options. When an option is written, the Fund receives a premium and becomes obligated to sell or purchase the underlying security, currency or other underlying financial instrument at a fixed price, upon exercise of the option.

Options can be traded through an exchange or through a privately negotiated arrangement with a dealer in an OTC transaction. Options traded through an exchange are generally cleared through a clearinghouse (such as The Options Clearing Corporation). The difference between the premium received or paid, and market value of the option, is recorded as unrealized appreciation or depreciation. The net change in unrealized appreciation or depreciation is reported in the Consolidated Statement of Operations. When an option is exercised, the cost of the security purchased or the proceeds of the security sale are adjusted by the amount of premium received or paid. Upon the expiration or closing of the option transaction, a gain or loss is reported in the Consolidated Statement of Operations.

Foreign Currency Options. The Fund may purchase or write call and put options on currencies to increase or decrease exposure to foreign exchange rate risk. A purchased call, or written put option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price. A purchased put, or written call option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

110       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

6. Use of Derivatives (Continued)

Index/Security Options. The Fund may purchase or write call and put options on individual equity securities and/or equity indexes to increase or decrease exposure to equity risk. A purchased call or written put option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price. A purchased put or written call option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

During the reporting period, the Fund had an ending monthly average market value of $1,587,816 and $861,420 on purchased call options and purchased put options, respectively.

Options written, if any, are reported in a schedule following the Consolidated Statement of Investments and as a liability in the Consolidated Statement of Assets and Liabilities. Securities held in collateral accounts to cover potential obligations with respect to outstanding written options are noted in the Consolidated Statement of Investments.

The risk in writing a call option is the market price of the underlying security increasing above the strike price and the option being exercised. The Fund must then purchase the underlying security at the higher market price and deliver it for the strike price or, if it owns the underlying security, deliver it at the strike price and forego any benefit from the increase in the price of the underlying security above the strike price. The risk in writing a put option is the market price of the underlying security decreasing below the strike price and the option being exercised. The Fund must then purchase the underlying security at the strike price when the market price of the underlying security is below the strike price. Alternatively, the Fund could also close out a written option position, in which case the risk is that the closing transaction will require a premium to be paid by the Fund that is greater than the premium the Fund received. When writing options, the Fund has the additional risk that there may be an illiquid market where the Fund is unable to close the contract. The risk in buying an option is that the Fund pays a premium for the option, and the option may be worth less than the premium paid or expire worthless.

During the reporting period, the Fund had an ending monthly average market value of $1,800,437 and $5,357,432 on written call options and written put options, respectively.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Swap Contracts

The Fund may enter into swap contract agreements with a counterparty to exchange a series of cash flows based on either specified reference rates, the price or volatility of asset or non-asset references, or the occurrence of a credit event, over a specified period. Swaps can be executed in a bi-lateral privately negotiated arrangement with a dealer in an OTC transaction (“OTC swaps”) or executed on a regulated market. Certain swaps, regardless of the venue of their execution, are required to be cleared through a clearinghouse (“centrally cleared swaps”). Swap contracts may include interest rate, equity, debt, index, total return, credit default, currency, and volatility swaps.

Swap contracts are reported on a schedule following the Consolidated Statement of Investments. The values of centrally cleared swap and OTC swap contracts are aggregated by positive and negative values and disclosed separately on the Consolidated Statement of

111       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

CONSOLIDATED FINANCIAL STATEMENTS Unaudited / Continued

6. Use of Derivatives (Continued)

Assets and Liabilities. The unrealized appreciation (depreciation) related to the change in the valuation of the notional amount of the swap is combined with the accrued interest due to (owed by) the Fund, if any, at termination or settlement. The net change in this amount during the period is included on the Consolidated Statement of Operations. The Fund also records any periodic payments received from (paid to) the counterparty, including at termination, under such contracts as realized gain (loss) on the Consolidated Statement of Operations.

Swap contract agreements are exposed to the market risk factor of the specific underlying reference rate or asset. Swap contracts are typically more attractively priced compared to similar investments in related cash securities because they isolate the risk to one market risk factor and eliminate the other market risk factors. Investments in cash securities (for instance bonds) have exposure to multiple risk factors (credit and interest rate risk). Because swaps have embedded leverage, they can expose the Fund to substantial risk in the isolated market risk factor.

Credit Default Swap Contracts. A credit default swap is a contract that enables an investor to buy or sell protection against a defined-issuer credit event, such as the issuer’s failure to make timely payments of interest or principal on a debt security, bankruptcy or restructuring. The Fund may enter into credit default swaps either by buying or selling protection on a corporate issuer, sovereign issuer, or a basket or index of issuers (the “reference asset”).

The buyer of protection pays a periodic fee to the seller of protection based on the notional amount of the swap contract. The seller of protection agrees to compensate the buyer of protection for future potential losses as a result of a credit event on the reference asset. The contract effectively transfers the credit event risk of the reference asset from the buyer of protection to the seller of protection.

The ongoing value of the contract will fluctuate throughout the term of the contract based primarily on the credit risk of the reference asset. If the credit quality of the reference asset improves relative to the credit quality at contract initiation, the buyer of protection may have an unrealized loss greater than the anticipated periodic fee owed. This unrealized loss would be the result of current credit protection being cheaper than the cost of credit protection at contract initiation. If the buyer elects to terminate the contract prior to its maturity, and there has been no credit event, this unrealized loss will become realized. If the contract is held to maturity, and there has been no credit event, the realized loss will be equal to the periodic fee paid over the life of the contract.

If there is a credit event, the buyer of protection can exercise its rights under the contract and receive a payment from the seller of protection equal to the notional amount of the swap less the market value of specified debt securities issued by the reference asset. Upon exercise of the contract the difference between such value and the notional amount is recorded as realized gain (loss) and is included on the Consolidated Statement of Operations.

The Fund may purchase or sell credit protection through credit default swaps to increase or decrease exposure to the credit risk of individual issuers and/or indexes of issuers that are either unavailable or considered to be less attractive in the bond market.

112       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

6. Use of Derivatives (Continued)

The Fund has engaged in spread curve trades by simultaneously purchasing and selling protection through credit default swaps referenced to the same reference asset but with different maturities. Spread curve trades attempt to gain exposure to credit risk on a forward basis by realizing gains on the expected differences in spreads.

For the reporting period, the Fund had ending monthly average notional amounts of $67,326,143 and $72,358,143 on credit default swaps to buy protection and credit default swaps to sell protection, respectively.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Interest Rate Swap Contracts. An interest rate swap is an agreement between counterparties to exchange periodic payments based on interest rates. One cash flow stream will typically be a floating rate payment based upon a specified floating interest rate while the other is typically a fixed interest rate.

The Fund may enter into interest rate swaps in which it pays the fixed or floating interest rate in order to increase or decrease exposure to interest rate risk. Typically, if relative interest rates rise, floating payments under a swap agreement will be greater than the fixed payments.

For the reporting period, the Fund had ending monthly average notional amounts of $583,549,091 and $861,352,492 on interest rate swaps which pay a fixed rate and interest rate swaps which receive a fixed rate, respectively.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Total Return Swap Contracts. A total return swap is an agreement between counterparties to exchange periodic payments based on the value of asset or non-asset references. One cash flow is typically based on a non-asset reference (such as an interest rate) and the other on the total return of a reference asset (such as a security or a basket of securities or securities index). The total return of the reference asset typically includes appreciation or depreciation on the reference asset, plus any interest or dividend payments.

Total return swap contracts are exposed to the market risk factor of the specific underlying financial instrument or index. Total return swaps are less standard in structure than other types of swaps and can isolate and/or include multiple types of market risk factors including equity risk, credit risk, and interest rate risk.

The Fund may enter into total return swaps to increase or decrease exposure to the credit risk of various indexes or basket of securities. These credit risk related total return swaps require the Fund to pay to, or receive payments from, the counterparty based on the movement of credit spreads of the related indexes or securities.

For the reporting period, the Fund had ending monthly average notional amounts of $27,112,529 on total return swaps which are long the reference asset.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

At period end, the Fund had no total return swap agreements outstanding.

Swaption Transactions

The Fund may enter into a swaption contract which grants the purchaser the right, but not

113       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

NOTES TO

6. Use of Derivatives (Continued)

the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. The purchaser pays a premium to the swaption writer who bears the risk of unfavorable changes in the preset terms on the underlying swap.

Purchased swaptions are reported as a component of investments in the Consolidated Statement of Investments and the Consolidated Statement of Assets and Liabilities. Written swaptions are reported on a schedule following the Consolidated Statement of Investments and their value is reported as a separate asset or liability line item in the Consolidated Statement of Assets and Liabilities. The net change in unrealized appreciation or depreciation on written swaptions is separately reported in the Consolidated Statement of Operations. When a swaption is exercised, the cost of the swap is adjusted by the amount of premium paid or received. Upon the expiration or closing of an unexercised swaption contract, a gain or loss is reported in the Consolidated Statement of Operations for the amount of the premium paid or received.

The Fund generally will incur a greater risk when it writes a swaption than when it purchases a swaption. When the Fund writes a swaption it will become obligated, upon exercise of the swaption, according to the terms of the underlying agreement. Swaption contracts written by the Fund do not give rise to counterparty credit risk prior to exercise as they obligate the Fund, not its counterparty, to perform. When the Fund purchases a swaption it only risks losing the amount of the premium it paid if the swaption expires unexercised. However, when the Fund exercises a purchased swaption there is a risk that the counterparty will fail to perform or otherwise default on its obligations under the swaption contract.

The Fund may purchase swaptions which give it the option to enter into an interest rate swap in which it pays a floating or fixed interest rate and receives a fixed or floating interest rate in order to increase or decrease exposure to interest rate risk. Purchasing the fixed portion of this swaption becomes more valuable as the reference interest rate decreases relative to the preset interest rate. Purchasing the floating portion of this swaption becomes more valuable as the reference interest rate increases relative to the preset interest rate.

The Fund may write swaptions which give it the obligation, if exercised by the purchaser, to enter into an interest rate swap in which it pays a fixed or floating interest rate and receives a floating or fixed interest rate in order to increase or decrease exposure to interest rate risk. A written swaption paying a fixed rate becomes more valuable as the reference interest rate increases relative to the preset interest rate. A written swaption paying a floating rate becomes more valuable as the reference interest rate decreases relative to the preset interest rate.

During the reporting period, the Fund had an ending monthly average market value of $6,221,859 and $4,778,359 on purchased and written swaptions, respectively.

Counterparty Credit Risk. Derivative positions are subject to the risk that the counterparty will not fulfill its obligation to the Fund. The Fund intends to enter into derivative transactions with counterparties that the Manager believes to be creditworthy at the time of the transaction.

The Fund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited

114       OPPENHEIMER GLOBAL STRATEGIC INCOME FUND

6. Use of Derivatives (Continued)

to the aggregate unrealized gain netted against any collateral held by the Fund. For OTC options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Options written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform.

To reduce counterparty risk with respect to OTC transactions, the Fund has entered into master netting arrangements, established within the Fund’s International Swap and Derivatives Association, Inc. (“ISDA”) master agreements, which allow the Fund to make (or to have an entitlement to receive) a single net payment in the event of default (close-out netting) for outstanding payables and receivables with respect to certain OTC positions in swaps, options, swaptions, and forward currency exchange contracts for each individual counterparty. In addition, the Fund may require that certain counterparties post cash and/or securities in collateral accounts to cover their net payment obligations for those derivative contracts subject to ISDA master agreements. If the counterparty fails to perform under these contracts and agreements, the cash and/or securities will be made available to the Fund.

ISDA master agreements include credit related contingent features which allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event that, for example, the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA master agreements, which would cause the Fund to accelerate payment of any net liability owed to the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Consolidated Statement of Assets and Liabilities. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

The Fund’s risk of loss from counterparty credit risk on exchange-traded derivatives cleared through a clearinghouse and for centrally cleared swaps is generally considered lower than as compared to OTC derivatives. However, counterparty credit risk exists with respect to initial and variation margin deposited/paid by the Fund that is held in futures commission merchant, broker and/or clearinghouse accounts for such exchange-traded derivatives and for centrally cleared swaps.

With respect to centrally cleared swaps, such transactions will be submitted for clearing, and if cleared, will be held in accounts at futures commission merchants or brokers that are members of clearinghouses. While brokers, futures commission merchants and clearinghouses are required to segregate customer margin from their own assets, in the event that a broker, futures commission merchant or clearinghouse becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker, futures commission merchant or clearinghouse for all its customers, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s, futures commission merchant’s or clearinghouse’s customers, potentially resulting in losses to the Fund.

There is the risk that a broker, futures commission merchant or clearinghouse will decline to

clear a transaction on the Fund’s behalf, and the Fund may be required to pay a termination fee to the executing broker with whom the Fund initially enters into the transaction. Clearinghouses may also be permitted to terminate centrally cleared swaps at any time. The Fund is also subject to the risk that the broker or futures commission merchant will improperly use the Fund’s assets deposited/paid as initial or variation margin to satisfy payment obligations of another customer. In the event of a default by another customer of the broker or futures commission merchant, the Fund might not receive its variation margin payments from the clearinghouse, due to the manner in which variation margin payments are aggregated for all customers of the broker/futures commission merchant.

Collateral and margin requirements differ by type of derivative. Margin requirements are established by the broker, futures commission merchant or clearinghouse for exchange-traded and cleared derivatives, including centrally cleared swaps. Brokers, futures commission merchants and clearinghouses can ask for margin in excess of the regulatory minimum, or increase the margin amount, in certain circumstances.

Collateral terms are contract specific for OTC derivatives. For derivatives traded under an ISDA master agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Fund or the counterparty.

For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Fund, if any, is reported separately on the Consolidated Statement of Assets and Liabilities as cash pledged as collateral. Non-cash collateral pledged by the Fund, if any, is noted in the Consolidated Statement of Investments. Generally, the amount of collateral due from or to a party must exceed a minimum transfer amount threshold (e.g. $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance.

9. 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 $200 million in assets	0.75%
Next $200 million in assets	0.72
Next $200 million in assets	0.69
Next $200 million in assets	0.66
Next $200 million in assets	0.60
Next $4 billion in assets	0.50
Next $5 billion in assets	0.48
Over $10 billion in assets	0.46

The Manager also provides investment management related services to the Subsidiary. The Subsidiary pays the Manager a monthly management fee at an annual rate according to the above schedule. The Subsidiary also pays certain other expenses including custody and directors’ fees.

The Fund’s effective management fee for the reporting period was 0.54% of average annual net assets before any Subsidiary management fees or any applicable waivers.

Sub-Adviser Fees. The Manager has retained the Sub-Adviser to provide the day-to-day portfolio management of the Fund and the Subsidiary. 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 and the Subsidiary, 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, which shall be calculated after any applicable fee waivers. Fees incurred and average net assets for each class with respect to these services are detailed in the Consolidated Statement of Operations and Consolidated 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

9. Fees and Other Transactions with Affiliates (Continued)

Transfer Agent pays the Sub-Transfer Agent an annual fee in monthly installments, equal to a 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’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 Trustees 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 Trustees. The Fund purchases shares of the funds selected for deferral by the Trustees 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 Consolidated 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 Plan are detailed in the Consolidated Statement of Operations.

Distribution and Service Plans for Class B, Class C and Class R Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class B, Class C and Class R 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 and 0.25% on Class R 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 Consolidated 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.

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to waive the management fee it receives from the Fund in an amount equal to the management fee it receives from the Subsidiary. During the reporting period, the Manager waived $50,662. This fee waiver and/or expense reimbursement may not be amended or withdrawn for one year from the date of the Fund’s prospectus, unless approved by the Board.

Effective for the period January 1, 2017 through December 31, 2017, the Transfer Agent voluntarily waived and/or reimbursed Fund expenses in an amount equal to 0.015% of average annual net assets for Classes A, B, C, R and Y.

During the reporting period, the Transfer Agent waived fees and/or reimbursed the Fund for transfer agent and shareholder servicing agent fees as follows:

Class A	$	116,550
Class B		472
Class C		25,781
Class R		4,651
Class Y		18,696

The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investments in Affiliated Funds. During the reporting period, the Manager waived fees and/or reimbursed the Fund $1,419,782 for these management fees. This fee waiver and/or expense reimbursement may not be amended or withdrawn for one year from the date of the Fund’s prospectus, unless approved by the Board.

Securities Sold Short. The Fund sells securities that it does not own, and it will therefore be obligated to purchase such securities at a future date. Upon entering into a short position, the Fund is required to segregate cash or securities at its custodian which are pledged for the

benefit of the lending broker and/or to deposit and pledge cash directly at the lending broker, with a value equal to a certain percentage, exceeding 100%, of the value of the securities that it sold short. Cash that has been segregated and pledged for this purpose will be disclosed on the Consolidated Statement of Assets and Liabilities; securities that have been segregated and pledged for this purpose are disclosed as such in the Consolidated Statement of Investments. The value of the open short position is recorded as a liability, and the Fund records an unrealized gain or loss to the extent of the difference between the proceeds received and the change in value of the open short position. The Fund records a realized gain or loss when the short position is closed out. By entering into short sales, the Fund bears the risk of an unlimited loss, since the price of the security sold short could theoretically increase without limit. Purchasing securities previously sold short to close out a short position can itself cause the price of the securities to rise further, thereby increasing the loss. Further, there is no assurance that a security the Fund needs to buy to cover a short position will be available for purchase at a reasonable price. Until the security is replaced, the Fund is required to pay the lender any dividend or interest earned. Dividend expense on short sales is treated as an expense in the Consolidated Statement of Operations.

At period end, the Fund had no outstanding securities sold short.

Joint Credit Facility. A number of mutual funds managed by the Manager participate in a $1.875 billion revolving credit facility (the “Facility”) intended to provide short-term financing, if necessary, subject to certain restrictions in connection with atypical redemption activity. Expenses and fees related to the Facility are paid by the participating funds and are disclosed separately or as other expenses on the Consolidated Statement of Operations. The Fund did not utilize the Facility during the reporting period.

The Fund’s voting record is available (i) without charge, upon request, by calling the Fund toll-free at 1.800.

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.

DISTRIBUTION SOURCES Unaudited

For any distribution that took place over the last six months of the Fund’s reporting period, the table below details on a per-share basis the percentage of the Fund’s total distribution payment amount that was derived from the following sources: net income, net profit from the sale of securities, and other capital sources. Other capital sources represent a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” You should not draw any conclusions about each Fund’s investment performance from the amounts of these distributions. This information is based upon income and capital gains using generally accepted accounting principles as of the date of each distribution. Because the Fund is actively managed, the relative amount of the Fund’s total distributions derived from various sources over the calendar year may change. Please note that this information should not be used for tax reporting purposes as the tax character of distributable income may differ from the amounts used for this notification. You will receive IRS tax forms in the first quarter of each calendar year detailing the actual amount of the taxable and non-taxable portion of distributions paid to you during the tax year.

For the most current information, please go to oppenheimerfunds.com. Select your Fund, and scroll down to the ‘Dividends’ table under ‘Analytics’. The Fund’s latest distribution information will be followed by the sources of any distribution, updated daily.

Protection of Information

We do not disclose any non-public personal information (such as names on a customer list) about current or former customers to anyone, except as permitted by law.

Disclosure of Information

Copies of confirmations, account statements and other documents reporting activity in your fund accounts are made available to your financial advisor (as designated by you). We may also use details about you and your investments to help us, our financial service affiliates, or firms that jointly market their financial products and services with ours, to better serve your investment needs or suggest educational material that may be of interest to you.

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.

● All transactions conducted via our websites, including redemptions, exchanges and purchases, are secured by the highest encryption standards available. 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 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.

How You Can Help

You can also do your part to keep your account information private and to prevent unauthorized transactions. If you obtain a user ID and password for your account, safeguard that information. Strengthening your online credentials–your online security profile–typically your user name, password, and security questions and answers, can be one of your most important lines of defense on the Internet.
