| <b>The Fund Summary</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Investment Objective.</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The Fund seeks capital appreciation. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Fees and Expenses of the Fund.</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. You may qualify for sales charge discounts if you (or you and your spouse) invest, or agree to invest in the future, at least $25,000 in certain funds in the Oppenheimer family of funds. More information about these and other discounts and sales charge waivers is available from your financial professional and in the section “About Your Account” beginning on page 18 of the prospectus, in the appendix to the prospectus titled “Special Sales Charge Arrangements and Waivers” and in the section “How to Buy Shares” beginning on page 52 in the Fund’s Statement of Additional Information. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Shareholder Fees</b><br/><br/>(fees paid directly from your investment) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Example.</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The following Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in a class of shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Any applicable fee waivers and/or expense reimbursements are reflected in the below examples for the first year only. Although your actual costs may be higher or lower, based on these assumptions your expenses would be as follows: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>If shares are redeemed</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>If shares are not redeemed </b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Portfolio Turnover. </b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Principal Investment Strategies.</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The Fund mainly invests in equity securities of issuers in emerging and developing markets throughout the world. Under normal market conditions, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of issuers that are economically tied to an emerging market country. For purposes of the 80% investment policy, the Fund considers an “emerging market country” to be one whose economy or markets are generally considered emerging or developing. The Fund typically invests in at least three emerging market countries. At times, the Fund may invest up to 100% of its total assets in securities of issuers in emerging and developing markets. In general, countries may be considered emerging or developing markets if they are included in any one of the Morgan Stanley Capital Index (“MSCI”) emerging markets indices, classified as an emerging or developing market, or classified under a similar or corresponding classification, by organizations such as the International Monetary Fund, or have economies, industries and stock markets with similar characteristics. For purposes of the 80% investment policy discussed above, a determination that an issuer is economically tied to an emerging market country is based on factors including, but not limited to, geographic location of its primary trading markets, location of its assets, its domicile or its principal offices, or whether it receives revenues or profits from goods produced or sold from, or investments made or services performed in, an emerging or developing market. Such a determination can also be based, in whole or in part, on identification of an issuer’s securities within an index or other listing indicating its location in an emerging or developing market country. The Fund may also invest in securities of issuers in less-developed emerging market countries that are not included in standard emerging market benchmarks or classifications and are traditionally less accessible to investors or in the early stages of capital market or economic development (such countries are commonly referred to as “frontier” market countries). Frontier market countries generally have smaller economies and less developed capital markets than traditional emerging and developing market countries. Investments in issuers in frontier market countries are included in the 80% of the Fund’s assets discussed in the investment policy above. The Fund seeks its investment objective by focusing on investments in securities of companies in emerging or developing markets that the Sub-Adviser believes are innovative in either, or a combination of, their products, services, processes, business models, management, use of technology, or approach to servicing geographic and consumer markets. The Fund invests primarily in common stocks, but can also invest in other equity securities, including preferred stocks, convertible securities, rights and warrants. The Fund may buy securities of issuers of any size, any market capitalization range and any industry or sector. Although the Fund can invest in securities of companies of any size and any market capitalization range, because innovative companies generally tend to have smaller market capitalizations, the Fund anticipates that it will generally have greater exposure to small- and mid-sized companies. The Fund may invest directly in certain eligible China A Shares through Stock Connect (a securities trading and clearing program designed to achieve mutual stock market access between the People’s Republic of China (“PRC”) and Hong Kong), or, for operational efficiency and regulatory considerations, through an investment in OFI Global China Fund, LLC (the “China Fund”), a private investment vehicle organized under Delaware law that intends to invest significantly in China A Shares and other securities available to certain qualified investors. The Sub-Adviser has full and exclusive discretionary authority to manage the day-to-day operations of the China Fund and to invest its assets. The Fund’s investment in the China Fund may vary based on the portfolio managers’ use of different types of investments that provide exposure to Chinese securities (through Stock Connect). Since the Fund may invest a portion of its assets in the China Fund, the Fund may be considered to be investing indirectly in such Chinese securities through the China Fund. In selecting investments for the Fund, the Sub-Adviser evaluates investment opportunities on a company-by-company basis. This approach includes fundamental analysis of a company’s financial statements, management record, capital structure, operations, product development, and competitive position in its industry. The portfolio managers also look for newer or established businesses that are entering, or expected to enter, into a growth cycle and have the potential for accelerating earnings growth or cash flow. The portfolio managers consider the effect of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends and seeks a diverse mix of industries and countries to help reduce the risks of foreign investing, such as currency fluctuations and stock market volatility. The portfolio managers take a broad view that stretches across industries, sectors, companies and a company’s operational functions, when considering whether a company is deemed to be innovative. The portfolio managers monitor individual issuers for changes in the factors above, which may trigger a decision to sell a security. These factors may vary in particular cases and may change over time. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| <b>Principal Risks.</b> | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The price of the Fund’s shares can go up and down substantially. The value of the Fund’s investments may fall due to adverse changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth less than what you paid for them. These risks mean that you can lose money by investing in the Fund. Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets. The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. 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. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities. The Fund seeks to invest substantially in the securities of companies that the Sub-Adviser believes are positioned for competitive advantage, above-average earnings growth or otherwise benefitting from opportunities in the global economy as a result of the perceived innovative nature of each company with respect to either, or a combination of, its products, services, processes, business models, management, use of technology, or approach to servicing geographic and consumer markets. No assurance can be made that a perceived innovation will result in the competitive advantage or growth anticipated by the Sub-Adviser or that such competitive advantage or growth may not be significantly delayed. Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry. Risks of Foreign Investing. Foreign securities 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. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s 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 only limited or no regulatory oversight. Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well-developed securities markets and exchanges that may be substantially less liquid than those of more developed markets. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in securities of issuers in developing or emerging market countries may be considered speculative. Frontier Market Risk. The risks associated with investments in frontier market countries include all the risks associated with investments in developing and emerging markets; however, these risks are magnified for frontier market countries. As a result, investments in companies in frontier market countries are generally subject to a higher risk of loss than investments in companies in traditional emerging and developing market countries due to less developed securities markets, different settlement procedures, greater price volatility, less developed governments and economies, more government restrictions, and the limited ability of foreign entities to participate in certain privatization programs. Investments in companies operating in frontier market countries are highly speculative in nature. Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s intended departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom. Risks of Investing in China A Shares. Investments in Class A Shares of Chinese companies involve certain risks and special considerations not typically associated with investments in U.S. companies, such as greater government control over the economy, political and legal uncertainty, currency fluctuations or blockage, the risk that the Chinese government may decide not to continue to support economic reform programs and the risk of nationalization or expropriation of assets. Additionally, the Chinese securities markets are emerging markets subject to the special risks applicable to developing and emerging market countries described elsewhere in this prospectus. Risks of Investing in the China Fund. The China Fund is not registered under the Investment Company Act of 1940. As an investor in the China Fund, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the China Fund is managed by OppenheimerFunds, Inc., which also serves as the Fund’s Sub-Adviser. Pursuant to an exemptive order granted on October 31, 2017 to the China Fund by the SEC, the China Fund is required to comply with the substantive requirements of a number of provisions of the Investment Company Act and the regulations thereunder. Further, the China Fund may invest substantially all of its assets in a limited number of issuers or a single issuer. To the extent that it does so, the China Fund is more subject to the risks associated with and developments affecting such issuers than a fund that invests more widely. Risks of Investing through Stock Connect. The Fund may invest directly in China A shares through Stock Connect, and will be subject to the following risks: sudden changes in quota limitations, application of trading suspensions, differences in trading days between the PRC and Stock Connect, operational risk, clearing and settlement risk and regulatory and taxation risk. Risks of Growth Investing. If a growth company’s earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth investing has gone in and out of favor during past market cycles and is likely to continue to do so. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price. Growth stocks may also be more volatile than other securities because of investor speculation. Risks of Small- and Mid-Cap Companies. Small-cap companies may be either established or newer companies, including “unseasoned” companies that have typically been in operation for less than three years. Mid-cap companies are generally companies that have completed their initial start-up cycle, and in many cases have established markets and developed seasoned market teams. While smaller companies might offer greater opportunities for gain than larger companies, they also may involve greater risk of loss. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Small- and mid-cap companies’ securities may trade in lower volumes and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Small- and mid-cap companies may not have established markets for their products or services and may have fewer customers and product lines. They may have more limited access to financial resources and may not have the financial strength to sustain them through business downturns or adverse market conditions. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. Small- and mid-cap companies may have unseasoned management or less depth in management skill than larger, more established companies. They may be more reliant on the efforts of particular members of their management team and management changes may pose a greater risk to the success of the business. It may take a substantial period of time before the Fund realizes a gain on an investment in a small- or mid-cap company, if it realizes any gain at all. Who is the Fund Designed For? The Fund is designed primarily for investors seeking capital appreciation. Those investors should be willing to assume the risks of short-term share price fluctuations and losses that are typical for a growth fund focusing on stocks of issuers in emerging and developing markets. The Fund is not designed for investors needing current income. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
