Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 9% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Principal Investment Strategies. The Fund is a special type of mutual fund known as a "fund of funds" because it primarily invests in other mutual funds. Those funds are referred to as the "Underlying Funds." The Underlying Funds mainly invest in foreign equity or debt securities, which are securities of companies organized under the laws of a foreign country, or with a substantial portion of their operations, assets, revenue or profits from businesses, investments or sales outside the United States or securities traded primarily in foreign securities markets. Certain Underlying Funds may invest 100% of their assets in securities of foreign companies. Some Underlying Funds may invest in emerging or developing markets as well as in developed markets throughout the world. From time to time an Underlying Fund may place greater emphasis on investing in one or more particular industry or region. Under normal market conditions, the Fund will invest in shares of some or all of the following Oppenheimer global or international funds (and their current target investment allocations in parentheses) that were chosen based on the Sub-Adviser's determination that they could provide growth of capital and/or investment income:

Oppenheimer Developing Markets Fund (15%)
Oppenheimer International Bond Fund (10%)
Oppenheimer International Growth Fund (30%)
Oppenheimer International Small Company Fund (15%)
Oppenheimer Master International Value Fund, LLC (30%)
Oppenheimer International Value Fund (0%)*

* As of April 30, 2013, the Fund's investment in Oppenheimer International Value Fund represented approximately 10% of the Fund's invested assets. Currently, the Fund does not intend to continue to allocate assets to Oppenheimer International Value Fund, but this may change in the future.

The Fund will typically invest in a minimum of three of the Underlying Funds and will not invest more than 50% of its net assets in any single Underlying Fund. The Sub-Adviser may change the weightings in the Underlying Funds at any time, without prior approval from or notice to shareholders. "Normal market conditions" are when securities markets and economic conditions are not unstable or adverse, in the judgment of the Sub-Adviser.

The Sub-Adviser will monitor the markets and allocate assets among the Underlying Funds based on changing market conditions and investment opportunities. In determining how much of the Fund's assets to invest in an Underlying Fund, the Sub-Adviser will seek to diversify the Fund's investments internationally and among different investment styles, larger and smaller market capitalizations and between developed and emerging markets. The Fund may change its emphasis on equity or fixed-income investments at times based on the Sub-Adviser's evaluation of the probable direction of interest rate changes. The Fund may also change its allocations based on the Sub-Adviser's evaluation of economic factors that it believes are not reflected in particular markets in which one or more of the Underlying Funds invest or on current or anticipated changes in currency valuations.

The Fund may hold a portion of its assets in cash, money market securities or other similar, liquid investments, including in shares of money market mutual funds in the Oppenheimer family of funds. This will generally occur at times when the Fund is unable to immediately invest funds received from purchases of Fund shares or from redemptions of other investments or to maintain liquidity.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Underlying Funds invest, because of Underlying Fund investment selection or the Fund's asset allocation, which could cause the Fund to underperform other funds with similar objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

The following summarizes the main risks that the Fund is subject to based on its investments in the Underlying Funds. The risks described below are risks to the Fund's overall portfolio. These are generally different from the main risks of any one Underlying Fund. While each Underlying Fund has its own particular risk characteristics, the strategy of allocating the Fund's assets to different Underlying Funds may allow those risks to be offset to some extent.

Main Risks of Investing in the Underlying Funds. Each of the Underlying Funds 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 Underlying Fund than in another, it will have greater exposure to the risks of that Underlying Fund. The investment objective and principal investment strategies of each of the Underlying Funds are described in the section "More Information About the Underlying Funds" beginning on page 37 of the Fund's prospectus. There is no guarantee that the Fund or any Underlying Fund will achieve its investment objective. The Underlying Funds will each pursue their investment objectives and policies without the approval of the Fund. If an Underlying Fund were to change its investment objective or policies, the Fund may be forced to sell its shares of that Underlying Fund at a disadvantageous time. The prospectuses and Statements of Additional Information of the Underlying Funds are available without charge by calling toll free at 1.800.225.5677 and can also be viewed and downloaded on the OppenheimerFunds website at www.oppenheimerfunds.com.

Main Risks of Foreign Investing. Foreign securities are subject to special risks. 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 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 securities denominated in that foreign currency. 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 U.S. or abroad, expropriation or nationalization of a company's assets, or other political and economic factors. These risks may be greater for investments in emerging or developing market countries. Foreign securities owned by an Underlying Fund may trade on weekends or other days when the Fund and the Underlying Funds do not price their shares. As a result, the Fund's net asset value may change on days when you will not be able to purchase or redeem the Fund's shares. Fund shareholders may be unable to deduct or take a credit for foreign taxes paid by the Underlying Funds on their foreign investments.

Special Risks of Developing and Emerging Markets. The economies of developing or emerging market countries may be more dependent on relatively few industries that may be highly vulnerable to local and global changes. The governments of developing and emerging market countries may also be more unstable than the governments of more developed countries. These countries generally have less developed securities markets or exchanges, and less developed legal and accounting systems. Securities may be more difficult to sell at an acceptable price and may be more volatile than securities in countries with more mature markets. The value of developing or emerging market 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 and restrictions on withdrawing assets from the country. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Allocation Risk. The Fund's ability to achieve its investment objective depends largely upon selecting the best mix of Underlying Funds. There is the risk that portfolio manager evaluations and assumptions regarding the Underlying Funds' prospects may be incorrect in view of actual market conditions.

Market Risk. The value of the securities in which the Underlying Funds invest may be affected by changes in the securities markets. Securities markets may experience significant short-term volatility and may fall sharply at times. Different markets may behave differently from each other and U.S. markets may move in the opposite direction from one or more foreign markets.

Main Risks of Investing in Equity Securities. Stocks and other equity securities held by the Underlying Funds fluctuate in price in response to changes in equity markets in general, and at times equity securities may be very volatile. The prices of individual equity securities may not all move in the same direction or at the same time. For example, "growth" stocks may perform well under circumstances in which "value" stocks in general have fallen. Other factors may affect the price of a particular company's securities. Those factors include poor earnings reports, loss of customers, litigation, or changes in regulations affecting the company or its industry. To the extent that an Underlying Fund emphasizes investments in securities of a particular type, for example foreign stocks, stocks of small- or mid-sized companies, growth or value stocks, or stocks of companies in a particular industry, its share value may fluctuate more in response to events affecting the market for those types of securities.

Main Risks of Investing in Debt Securities. Debt securities held by the Underlying Funds may be subject to interest rate risk, duration risk, credit risk, credit spread risk, prepayment risk, reinvestment risk, extension risk and event risk. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may be worth less than the amount the Underlying Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are at, or near, historic lows. Duration risk is the risk that longer-duration debt securities will be more volatile and more likely to decline in price in a rising interest rate environment than shorter-duration debt securities. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Underlying Fund's income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer's credit rating, for any reason, can also reduce the market value of the issuer's securities. "Credit spread" is the difference in yield between securities that is due to differences in their credit quality. There is a risk that credit spreads may increase when the market expects lower-grade bonds to default more frequently. When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Underlying Fund's holdings may fall sharply (referred to as "extension risk"). When interest rates fall, the Underlying Fund may be required to reinvest the proceeds from a security's sale or redemption at a lower interest rate (referred to as "reinvestment risk"). Prepayment risk is the risk that, when interest rates fall, the issuer will redeem the security prior to the security's expected maturity, or that borrowers will repay the loans that underlie these debt securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to expected maturity. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Fixed-Income Market Risks. Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns can cause increased volatility in those debt securities or debt securities markets. Under some circumstances, as was the case during the latter half of 2008 and early 2009, those concerns could cause reduced liquidity in certain debt securities markets. A lack of liquidity or other adverse credit market conditions may hamper an Underlying Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Special Risks of Lower-Grade Securities. Lower-grade debt securities, whether rated or unrated, have greater risks than investment-grade securities. They may be subject to greater price fluctuations and have a greater risk that the issuer might not be able to pay interest and principal when due. The market for lower-grade securities may be less liquid and therefore they may be harder to value or to sell at an acceptable price, especially during times of market volatility or decline.

Affiliated Portfolio Risk. In managing the Fund, the Manager and the Sub-Adviser will have authority to select and substitute Underlying Funds. The Manager and Sub-Adviser may be subject to potential conflicts of interest in selecting Underlying Funds because the fees paid to each by some Underlying Funds for its advisory services are higher than the fees paid by other Underlying Funds. However, the Manager and Sub-Adviser monitor the investment process to seek to identify, address and resolve any potential issues.

Who Is the Fund Designed For? The Fund is designed primarily for investors seeking capital appreciation from a variety of global and international investments. Those investors should be willing to assume the risks of short-term share price fluctuations that are typical for foreign investments. 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.
