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. 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 102% of the average value of its portfolio.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies.
The Fund buys a variety of different types of securities to seek its investment objective. The Fund may invest in equity securities and debt securities of both domestic and foreign issuers and in issuers in any capitalization range. There is no limit on the amount of the Fund's assets that can be invested in foreign securities in developed markets. However, the Fund does not normally expect to invest more than 35% of its total assets in foreign issuers and may not invest more than 10% of its net assets in the securities of governments and companies in emerging markets and it may not invest more than 20% of its net assets in foreign debt securities.
In selecting securities to buy, the portfolio managers use different investment styles to seek diversification across asset classes. They normally maintain a mix of stocks, debt securities and cash, although the Fund is not required to allocate its assets in any fixed proportion. The Fund's asset allocations will change over time as the portfolio managers seek relative opportunities but will generally include:
-
Equity securities: Equity securities are securities that represent an ownership interest in a company. They include common stock, preferred stock and securities convertible into common stock. The Fund will normally invest in stocks and other equity securities, primarily common stocks of U.S. and foreign companies. In selecting equity securities to buy, the portfolio managers mainly look for potential capital appreciation. The portfolio managers employ a "value" style in selecting stocks. Value investing uses fundamental analysis to seek companies whose intrinsic value is greater than the current price of their securities.
-
Debt securities: Debt securities are securities representing money borrowed by the issuer that must be repaid, specifying the amount of principal, the interest or discount rate, and the time or times at which payments are due. The Fund will normally invest in fixed-income senior securities, such as bonds and notes. The debt securities the Fund may buy include securities issued by U.S. and foreign companies, securities issued or guaranteed by the U.S. Government and its agencies and instrumentalities, mortgage-related securities (including private issuer mortgage-backed securities), debt obligations of foreign governments, and money market instruments. The Fund may invest without limit in lower-grade, high-yield debt securities, sometimes referred to as "junk bonds". In selecting debt securities to buy, the portfolio managers look for both income and for total return. The Fund has no requirements as to the maturity of the debt securities it can buy and the average maturity of the Fund's portfolio can be expected to change over time. The Fund may invest in debt securities that pay interest at fixed or floating rates.
-
Derivative Securities: The Fund may also invest in derivative instruments. A derivative is an instrument whose value depends on (or is derived from) the value of an underlying asset or other measure. The derivative instruments in which the Fund may invest include: options, futures, forward contracts, swaps, "structured" notes and "zero-coupon" and "stripped" securities that pay only the interest or only the principal portion of a debt obligation. When interest rates change, the prices of those securities may go up or down more than the prices of other types of debt securities.
In seeking diversification of the Fund's portfolio over asset classes, issuers, and economies, the portfolio managers consider overall and relative economic conditions in U.S. and foreign markets. At times, the Fund may focus more on investing for capital appreciation with less emphasis on seeking income. At other times, perhaps when stock markets are less stable, the Fund might have a greater relative emphasis on income-seeking investments, such as government securities and money market instruments.
The Fund may buy foreign currencies but only in connection with the purchase and sale of foreign securities and not for speculation.

|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Equity Securities. 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 markets.
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: 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.
Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk and extension risk. 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 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. 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 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. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates.
Although some of the securities that the Fund invests in are issued or guaranteed by the U.S. government or it agencies or instrumentalities, the Fund also invests in securities issued by private issuers, which do not have any government guarantees. While the Fund's investments in U.S. Government securities may be subject to little credit risk, the Fund's other investments in debt securities, particularly high-yield lower-grade debt securities and mortgage-backed securities, are subject to risks of default.
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 the 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 securities, whether rated or unrated, may be subject to wider market fluctuation, greater credit risk and greater risk of loss of income and principal than investment-grade securities. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.
Main Risks of Value Investing. Value investing entails the risk that if the market does not recognize that the Fund's securities are undervalued, the prices of those securities might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause the Fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of "value" companies may underperform the securities of "growth" companies.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
Main Risks of Derivative Investments. Derivatives may be volatile, may require the payment of premiums, can increase portfolio turnover, may be illiquid, and may not perform as expected. Derivatives are subject to counter-party risk and the Fund may lose money on a derivative investment if the issuer or counter-party fails to pay the amount due. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund 's initial investment.
Asset Allocation Risk. Because the Fund typically invests in a combination of securities, the Fund's ability to achieve its investment objective depends largely upon selecting the best mix of investments. There is the risk that the portfolio manager's evaluations and assumptions regarding the equity and fixed-income markets' prospects may be incorrect in view of actual market conditions. During periods of rapidly rising prices, the Fund might not achieve growth in its share prices to the same degree as funds focusing only on stocks. The Fund's investments in stocks may make it more difficult to preserve principal during periods of stock market volatility. The Fund's use of a value or growth style might not be successful when the particular strategy is out of favor.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking high total return from their investment from a fund that allocates its assets among different types of securities. Those investors should be willing to assume the risks of short-term share price fluctuations that are typical for a fund that invests in stocks and foreign securities. The Fund is not a short-term trading vehicle and is not designed for investors needing an assured level of current income but may be appropriate for longer-term investors. 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.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund mainly invests in common stocks of "growth companies." Growth companies are companies whose earnings and stock prices are expected to increase at a faster rate than the overall market. These may be newer companies or established companies of any capitalization range that the portfolio manager believes may appreciate in value over the long term. Currently, the Fund primarily focuses on established companies that are similar in size to companies in the S&P 500 Index or the Russell 1000 Growth Index. The Fund primarily invests in securities of U.S. issuers but may also invest in foreign securities. The portfolio manager looks for growth companies with stock prices that she believes are reasonable in relation to overall stock market valuations. In seeking broad diversification of the Fund's portfolio among industries and market sectors, the portfolio manager focuses on a number of factors that may vary in particular cases and over time. Currently, the portfolio manager looks for:
-
companies in business areas that have above-average growth potential,
-
companies with growth rates that the portfolio manager believes are sustainable over time,
-
stocks with reasonable valuations relative to their growth potential.
The Fund may sell the stocks of companies that the portfolio manager believes no longer meet the above criteria, but is not required to do so.

| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.
Main 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.
Who Is The Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies, for investors seeking capital appreciation in their investment over the long term, from investments in common stocks of well-known companies. Those investors should be willing to assume the risks of short-term share price fluctuations that are typical for a fund focusing on stocks. Because of its focus on long-term growth, the Fund may be more appropriate for investors with longer-term investment goals. The Fund is not designed for investors needing an assured level of current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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. |

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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund. |

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. 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 99% of the average value of its portfolio.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in investment-grade debt securities (generally referred to as "bonds"). A debt security is a security representing money borrowed by the issuer that must be repaid. The terms of a debt security specify the amount of principal, the interest rate or discount, and the time or times at which payments are due. Debt securities can include:
-
Domestic and foreign corporate debt obligations;
-
Domestic and foreign government debt obligations, including U.S. Government securities;
-
Mortgage-related securities;
-
Asset-backed securities; and
-
Other debt obligations.
The portfolio managers' overall strategy is to build a diversified portfolio of corporate and government bonds. The Fund's investments in U.S. Government securities may include securities issued or guaranteed by the U.S. Government or by its agencies or federally-chartered entities referred to as "instrumentalities." There is no required allocation of the Fund's assets among the classes of securities, but the Fund focuses mainly on U.S. Government securities and investment-grade corporate debt securities. When market conditions change, the portfolio managers might change the Fund's relative asset allocation.
The Fund can invest up to 20% of its total assets in lower-grade, high-yield debt securities that are below investment-grade (commonly referred to as "junk bonds"). "Investment-grade" debt securities are rated in one of the top four rating categories by nationally recognized statistical rating organizations such as Moody's or Standard & Poor's. The Fund may also invest in unrated securities, in which case the Fund's investment adviser, OppenheimerFunds, Inc., may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Manager's credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization.
The Fund has no limitations on the range of maturities of the debt securities in which it can invest and may hold securities with short-, medium- or long-term maturities. The maturity of a security differs from its effective duration, which attempts to measure the expected volatility of a security's price to interest rate changes. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bond's value to decrease about 3%. To try to decrease volatility, the Fund seeks to maintain a weighted average effective portfolio duration of three to six years, measured on a dollar-weighted basis using the effective duration of the securities included in its portfolio and the amount invested in each of those securities. However, the duration of the portfolio might not meet that target due to market events or interest rate changes that cause debt securities to be repaid more rapidly or more slowly than expected.
The Fund may invest in foreign debt securities, including securities issued by foreign governments or companies in both developed and emerging markets.
The Fund may also use derivatives to seek increased returns or to try to manage investment risks. Futures, swaps and "structured" notes are examples of some of the types of derivatives the Fund can use.
In selecting investments for the Fund, the Fund's portfolio managers analyze the overall investment opportunities and risks in different sectors of the debt securities markets by focusing on business cycle analysis and relative values between the corporate and government sectors. The Fund mainly seeks income earnings on the Fund's investments plus capital appreciation that may arise from decreases in interest rates, from improving credit fundamentals for a particular sector or security or from other investment techniques.
The Fund may sell securities that the portfolio managers believe no longer meet the above criteria.

|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk and extension risk. 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 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. 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 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. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates.
Special Risks of Lower-Grade Securities.
Lower-grade securities, whether rated or unrated, may be subject to wider market fluctuation, greater credit risk and greater risk of loss of income and principal than investment-grade securities. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.
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 the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.
Because the Fund can invest up to 20% of its total assets in lower-grade securities, the Fund's credit risks are greater than those of funds that buy only investment-grade securities.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
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.
Main Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. The Fund may also lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Certain derivative investments may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and can increase portfolio turnover. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and other investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking total return from a fund that invests mainly in investment-grade debt securities but which can also hold high-yield, below investment-grade securities. Those investors should be willing to assume the risks of a fund that typically invests a significant amount of its assets in corporate-debt securities and the changes in debt securities prices that can occur when interest rates change. The Fund is intended to be a long-term investment, not a short-term trading vehicle. Because the Fund's income will fluctuate, it is not designed for investors needing an assured level of current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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.

| Objective, Primary [Text Block] |

Investment Objective.
The Fund seeks long-term capital appreciation by investing a substantial portion of its assets in securities of foreign issuers, "growth-type" companies, cyclical industries and special situations that are considered to have appreciation possibilities.

|
| Expense Narrative [Text Block] |
rr_ExpenseNarrativeTextBlock |
Fees and Expenses of the Fund. This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. The accompanying prospectus of the participating insurance company provides information on initial or contingent deferred sales charges, exchange fees or redemption fees for that variable life insurance policy, variable annuity or other investment product. The fees and expenses of those products are not charged by the Fund and are not reflected in this table. Expenses would be higher if those fees were included.

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. 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 13% of the average value of its portfolio.

Example. 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. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your expenses would be as follows, whether or not you redeemed your shares:

|
| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund invests mainly in common stock of U.S. and foreign companies. The Fund can invest without limit in foreign securities and can invest in any country, including countries with developed or emerging markets. However, the Fund currently has more of its assets invested in developed markets such as the United States, Western European countries and Japan.
As a fundamental policy, the Fund normally will invest in at least three countries (one of which may be the United States). Typically, the Fund invests in a number of different countries. The Fund is not required to allocate its investments in any set percentages in any particular countries.
The portfolio manager also considers the effect of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends. The trends currently considered include: mass affluence, new technologies, corporate restructuring and demographic changes. The portfolio manager does not invest any fixed amount of the Fund's assets according to these criteria and the trends that are considered may change over time.
In seeking diversification of the Fund's portfolio, the portfolio manager generally seeks companies with the following characteristics, which may vary in particular cases and may change over time:
-
Worldwide growth-oriented companies of any market capitalization;
-
Companies at attractive valuations that may benefit from global growth trends;
-
Companies with strong competitive positions and high demand for their products or services;
-
Cyclical opportunities in the business cycle and sectors or industries that may benefit from those opportunities; and
-
Special situations such as mergers, reorganizations, restructurings or other unusual events.
The Fund does not limit its investments to companies in a particular market capitalization range, but primarily invests in large-cap companies. A company's market capitalization is the value of its outstanding common stock. Relative to other companies, a company may be classified as small-cap, mid-cap or large-cap.
The Fund may sell the stocks of companies that the portfolio manager believes no longer meet the above criteria, but it is not required to do so.
|
|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.
Main 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.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
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.
Investing in Special Situations. At times, the Fund may seek to benefit from what it considers to be "special situations," such as mergers, reorganizations, restructurings or other unusual events that are expected to affect a particular issuer. There is a risk that the expected change or event might not occur, which could cause the price of the security to fall, perhaps sharply. In that case, the investment might not produce the expected gains or might cause a loss. This is an aggressive investment technique that may be considered speculative.
Cyclical Opportunities. At times, the Fund might seek to take advantage of short-term market movements or changes in the business cycle by investing in companies or industries that are sensitive to those changes. For example, when the economy is expanding, companies in consumer durables and the technology sector might benefit. There is a risk that, if a cyclical event does not have the anticipated effect or when the issuer or industry is out of phase in the business cycle, the value of the Fund's investment could fall.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking capital appreciation over the long term. Those investors should be willing to assume the risks of short-term share price fluctuations that are typical for a fund that focuses on stocks and foreign securities. Because of its focus on long-term growth, the Fund may be more appropriate for investors with longer term investment goals. 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.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. Under normal market conditions, the Fund invests at least 80% of its net assets, including any borrowings for investment purposes, in debt securities. A debt security is a security representing money borrowed by the issuer that must be repaid, specifying the amount of principal, the interest rate or discount, and the time or times at which payments are due.
The Fund invests mainly in issuers in three market sectors: (1) foreign governments and companies, (2) U.S. government securities, and (3) lower-grade, high-yield securities (commonly referred to as "junk bonds") of U.S. and foreign companies. However, the Fund is not required to invest in all three sectors at all times, and the amount of its assets in each of the three sectors will vary over time. The Fund can invest up to 100% of its assets in any one sector at any time, if the Fund's portfolio managers believe that it offers the best investment opportunity. Under normal market conditions, the Fund will invest a substantial portion of its assets in a number of different countries, including the U.S. The Fund is not required to allocate its investments in any set percentages in any particular countries.
The portfolio managers analyze the overall investment opportunities and risks among the three market sectors in which the Fund invests and seek to moderate the special risks of investing in lower-grade, high-yield debt instruments and foreign securities by building a broadly diversified portfolio. The Fund's diversification strategies are intended to help reduce share price volatility while seeking current income. The portfolio managers currently focus on securities offering high current income, securities whose market prices tend to move in different directions (to seek overall portfolio diversification), and relative values among the three market sectors in which the Fund invests. These factors may vary in particular cases and may change over time.
The portfolio managers actively manage foreign currency exposure to seek to reduce risk and enhance return. To do so, the Fund may invest in foreign exchange derivatives, including forwards and options that reference foreign currencies, including currencies of developing and emerging market countries.
The Fund's foreign investments may include debt securities issued by foreign governments or companies in both developed markets and emerging markets. The Fund has no requirements regarding the range of maturities of the debt securities it can buy or the market capitalization of the issuers of those securities.
The Fund can invest in investment grade or lower-grade, high-yield debt securities. "Investment grade" debt securities are rated in one of the top four rating categories by nationally recognized statistical rating organizations such as Moody's Investors Service or Standard & Poor's. The Fund may also invest in unrated securities, in which case the Fund's investment adviser, OppenheimerFunds, Inc., may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Manager's credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. The Fund's debt investments typically include: U.S. and foreign government bonds and notes, collateralized mortgage obligations (CMOs) and other mortgage-related securities, domestic and foreign corporate debt obligations, "structured" notes, "zero coupon" and "stripped" securities, participation interests in loans, investments in loan pools and asset-backed securities. The Fund normally invests a substantial amount of its assets in lower-grade, high-yield debt securities, and can do so without limit.
The Fund may also use certain types of derivative instruments for investment purposes or for hedging, including: options, futures, forward contracts, swaps, certain mortgage-related securities, "structured"notes, and event-linked bonds.
The Fund may sell securities that the portfolio managers believe are no longer favorable based on these factors.
The Fund has established a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the "Subsidiary"). The Fund may invest up to 25% of its total assets in the Subsidiary. The Subsidiary invests primarily in commodity-linked derivatives (including commodity futures, financial futures, options and swap contracts) and exchange traded funds related to gold or other special minerals ("Gold ETFs"). The Subsidiary may also invest in certain fixed-income securities and other investments that may serve as margin or collateral for its derivatives positions. Investments in the Subsidiary are intended to provide the Fund with exposure to commodities market returns within the limitations of the federal tax requirements that apply to the Fund. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. The Fund's investment in the Subsidiary may vary based on the portfolio managers' use of different types of commodity-linked derivatives, fixed-income securities, Gold ETFs, and other investments. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund's indirect investments through the Subsidiary.

| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk and extension risk. 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 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. 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 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. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates.
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 the 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 securities, whether rated or unrated, may be subject to wider market fluctuation, greater credit risk and greater risk of loss of income and principal than investment-grade securities. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.
Because the Fund can invest without limit in lower-grade securities, the Fund's credit risks are greater than those of funds that buy only investment-grade securities.
Special Risks of Sovereign Debt.
Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.
Sector Allocation Risk. In allocating investments among its three principal market sectors, the Fund seeks to take advantage of the potential lack of performance correlation between those sectors. There is the risk that the evaluations regarding the sectors' relative performance may be incorrect and those sectors may all perform in a similar manner under certain market conditions.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
Foreign Currency Risk.
Fluctuations in foreign currency values will result in fluctuations in the U.S. dollar value of securities denominated in that foreign currency. If the U.S. dollar rises in value against a foreign currency, a security denominated in that currency will be worth less in U.S. dollars and if the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency will be worth more in U.S. dollars. The dollar value of foreign investments may also be affected by exchange controls.
The portfolio manager's selection of foreign currency denominated investments may not perform as expected. Currency derivative investments may be particularly volatile and subject to greater risks than other types of foreign-currency denominated 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.
Main Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. The Fund may also lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Certain derivative investments may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and can increase portfolio turnover. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful.
Main Risks of Commodity-Linked Investments. Commodity-linked investments are considered speculative and have substantial risks, including the risk of loss of a significant portion of their principal value. Prices of commodities and commodity-linked investments may fluctuate significantly over short periods due to a variety of factors, including for example agricultural, economic and regulatory developments. These risks may make commodity-linked investments more volatile than other types of investments.
Main Risks Of Investments In The Fund's Wholly-Owned Subsidiary. The Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to its investor protections (except as otherwise noted in this prospectus). As an investor in the Subsidiary, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Subsidiary is wholly-owned and controlled by the Fund and managed by the Manager. Therefore, the Fund's ownership and control of the Subsidiary make it unlikely that the Subsidiary would take actions contrary to the interests of the Fund or its shareholders.
Changes in the laws of the Cayman Islands (where the Subsidiary is organized) could prevent the Subsidiary from operating as described in this prospectus and could negatively affect the Fund and its shareholders. For example, the Cayman Islands currently does not impose certain taxes on exempted companies like the Subsidiary, including income and capital gains tax, among others. If Cayman Islands laws were changed to require such entities to pay Cayman Islands taxes, the investment returns of the Fund would likely decrease.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and other investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking high current income from a fund that invests in a variety of domestic and foreign debt securities, including government and lower-grade debt securities. Those investors should be willing to assume the greater risks of short-term share price fluctuations and the special credit risks that are typical for a fund that invests mainly in lower-grade fixed-income securities and foreign securities. The Fund does not seek capital appreciation. The Fund is not designed for investors needing an assured level of current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund invests in a variety of high-yield debt securities and related instruments. Those investments primarily include lower-grade corporate bonds. To a lesser extent, the Fund's investments include foreign corporate and government bonds, as well as swaps, including single name and index-linked credit default swaps.
Under normal market conditions, the Fund invests at least 65% of its total assets in high-yield, lower-grade, fixed-income securities, also referred to as "junk" bonds. The remainder of the Fund's assets may be invested in other debt securities, common stocks (and other equity securities), cash or cash equivalents, when the Manager believes these investments are consistent with the Fund's objectives. The Fund has no requirements as to the range of maturities of the debt securities it can buy or as to the market capitalization of the issuers of those securities.
The Fund's debt securities may be rated by nationally recognized statistical rating organizations such as Moody's Investors Service or Standard & Poor's or may be unrated.
Lower-grade debt securities are those rated below "BBB" by Standard & Poor's or below "Baa" by Moody's Investors Service, or that have comparable ratings from other nationally recognized rating organizations. Additionally, the portfolio managers may internally assign ratings to certain of the Fund's unrated securities, after assessing their credit quality, in categories equivalent to those of nationally recognized statistical rating organizations. The Fund may also invest in unrated securities, in which case the Manager may internally assign ratings to certain of those securities, after assessing their credit quality, in categories similar to those of nationally recognized statistical rating organizations.
The Fund may invest in securities of U.S. or foreign issuers. When it does so, the Fund will tend to focus on securities of foreign issuers in developing markets. The Fund also uses certain types of derivative investments to try to enhance income or to try to manage ("hedge") investment risks, including: options, futures contracts, swaps, "structured" notes, and certain mortgage-related securities.
In selecting securities, the portfolio manager seeks to build a broadly diversified portfolio to try to moderate the special risks of investing in high-yield debt instruments. The portfolio manager currently uses a "bottom up" approach, focusing on the performance of individual securities while considering industry trends. He evaluates an issuer's liquidity, financial strength and earnings power. The Fund's portfolio manager also analyzes the overall investment opportunities and risks in different market sectors, industries and countries. The portfolio manager currently focuses on the following factors, which may vary in particular cases and may change over time:
-
Issuers with earnings growth rates that are faster than the growth rate of the overall economy,
-
Issuers with improvements in relative cash flows and liquidity to help them meet their obligations,
-
Corporate sectors that in the portfolio manager's view are undervalued in the marketplace,
-
Changes in the business cycle that might affect corporate profits, and
-
Securities or sectors that will help the overall diversification of the portfolio.
The Fund may sell securities that the portfolio manager believes no longer meet the above criteria.

| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk and extension risk. 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 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. 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 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. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates.
Special Risks of Lower-Grade Securities.
Lower-grade securities, whether rated or unrated, may be subject to wider market fluctuation, greater credit risk and greater risk of loss of income and principal than investment-grade securities. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.
Because the Fund can invest without limit in lower-grade securities, the Fund's credit risks are greater than those of funds that buy only investment-grade securities.
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 the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
Time-Zone Arbitrage.
The Fund may invest in securities of foreign issuers that are traded in U.S. or foreign markets. If the Fund invests a significant amount of its assets in foreign markets, it may be exposed to "time-zone arbitrage" attempts by investors seeking to take advantage of differences in the values of foreign securities that might result from events that occur after the close of the foreign securities market on which a security is traded and before the Fund's net asset value is calculated. If such time-zone arbitrage were successful, it might dilute the interests of other shareholders. The Fund's use of "fair value pricing" to adjust certain market prices of foreign securities may help deter those activities.
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.
Main Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. The Fund may also lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Certain derivative investments may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and can increase portfolio turnover. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful.
Who Is The Fund Designed For?
The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking high current income from a fund that invests mainly in lower grade U.S. and foreign debt securities. Those investors should be willing to assume the greater risks of short-term share price fluctuations and the special credit risks that are typical for a fund that invests mainly in lower grade fixed-income securities. The Fund is intended to be a long-term investment, not a short-term trading vehicle. Because the Fund's income will fluctuate, it is not designed for investors needing an assured level of current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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.

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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund. |

Fees and Expenses of the Fund. This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. The accompanying prospectus of the participating insurance company provides information on initial or contingent deferred sales charges, exchange fees or redemption fees for that variable life insurance policy, variable annuity or other investment product. The fees and expenses of those products are not charged by the Fund and are not reflected in this table. Expenses would be higher if those fees were included.

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. 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 38% of the average value of its portfolio.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies.
The Fund mainly invests in common stocks of U.S. companies of different capitalization ranges. The Fund currently focuses on "larger capitalization" issuers, which are considered to be companies with market capitalizations equal to the companies in the Russell 1000 Index. The portfolio managers use fundamental research and quantitative models to select securities for the Fund's portfolio, which is comprised of both growth and value stocks. While the process may change over time or vary in particular cases, in general the selection process currently uses:
-
a fundamental approach in analyzing issuers on factors such as a company's financial performance and prospects, industry position, and business model and management strength. Industry outlook, market trends and general economic conditions may also be considered.
-
quantitative models to rank securities within each sector to identify potential buy and sell candidates for further fundamental analysis. A number of company-specific factors are analyzed in constructing the models, including valuation, fundamentals and momentum.
The portfolio is constructed and regularly monitored based upon several analytical tools, including quantitative investment models. The Fund aims to maintain a broadly diversified portfolio across major economic sectors by applying investment parameters for both sector and position size. The portfolio managers use the following sell criteria: the stock price is approaching its target, deterioration in the company's competitive position, poor execution by the company's management, or identification of more attractive alternative investment ideas.
|
|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.
Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking high total return. Those investors should be willing to assume the risks of short-term share price fluctuations that are typical for a fund that focuses on stocks. 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.

Fees and Expenses of the Fund. This table describes the fees and expenses that you may pay if you buy and hold or redeem shares of the Fund. The accompanying prospectus of the participating insurance company provides information on initial or contingent deferred sales charges, exchange fees or redemption fees for that variable life insurance policy, variable annuity or other investment product. The fees and expenses of those products are not charged by the Fund and are not reflected in this table. Expenses would be higher if those fees were included.

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. 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 108% of the average value of its portfolio.

|
| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund mainly invests in common stocks of "small-cap" and "mid-cap" companies. A company's "market capitalization" is the value of its outstanding common stock. Under normal market conditions, the Fund will invest at least 80% of its net assets, including any borrowings for investment purposes, in securities of companies having a market capitalization in the range of the Russell 2500™ Index, a measure of small- to mid-cap issuers. The capitalization range of that index is subject to change due to market activity or changes in the composition of the index. The range of the Russell 2500™ Index generally widens over time and it is reconstituted annually to preserve its small- and mid-cap character. The Fund measures a company's capitalization at the time the Fund buys a security and is not required to sell a security if the company's capitalization moves outside of the Fund's capitalization definition.
The portfolio managers use both fundamental research and quantitative models to identify investment opportunities. While the process may change over time or vary in particular cases, in general the selection process currently:
-
aims to maintain broad diversification across all major economic sectors;
-
uses quantitative models, including sector-specific factors, to rank securities within each economic sector;
-
uses a fundamental approach to analyze issuers based on factors such as a company's financial performance, competitive strength, industry position, business practices and management; and
-
considers market trends, current industry outlooks and general economic conditions.
In constructing the portfolio, the Fund seeks to limit exposure to so-called "top-down" or "macro" risks, such as overall stock market movements, economic cycles, and interest rate or currency fluctuations. Instead, the portfolio managers seek to add value by selecting individual securities with superior company-specific fundamental attributes or relative valuations that they expect to outperform their industry and sector peers. This is commonly referred to as a "bottom-up" approach to portfolio construction.
The portfolio managers consider stock rankings, benchmark weightings and capitalization outlooks in determining security weightings for individual issuers. Although the Fund mainly invests in U.S. companies, it can invest in securities issued by companies or governments in any country. The Fund primarily invests in common stock but may also invest in other types of securities, such as units of master limited partnerships or other securities that are consistent with its investment objective.
The portfolio managers might sell a security if the price is approaching their price target, if the company's competitive position has deteriorated or the company's management has performed poorly, or if they have identified more attractive investment prospects.

|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.
Investing in Small Unseasoned Companies.
The Fund can invest in the securities of small unseasoned companies. These are companies that have been in operation for less than three years, including the operations of any predecessors. In addition to the other risks of smaller issuers, these securities may have a very limited trading market, making it harder for the Fund to sell them at an acceptable price. The price of these securities may be very volatile, especially in the short term.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking capital appreciation over the long term. Those investors should be willing to assume the greater risks of short-term share price fluctuations that are typical for a fund focusing on stocks of small and medium sized companies. The Fund is not designed for investors needing current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund is a money market fund that invests in a variety of money market instruments to seek current income. Money market instruments are short-term, high-quality, dollar-denominated debt instruments issued by the U.S. Government, domestic and foreign corporations and financial institutions, and other entities. Money market instruments include bank obligations, repurchase agreements, commercial paper, and other short-term corporate and governmental debt obligations.
To be considered "high-quality," a debt instrument must be rated in one of the two highest credit-quality categories for short-term securities by a nationally recognized statistical rating service or, if a security is unrated, it must be determined by the Fund's investment manager, OppenheimerFunds, Inc. (the "Manager"), under the supervision of the Fund's Board, to be of comparable quality to rated securities in one of those two categories.
|
|
| Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
Principal Risks. All investments carry risks to some degree. The Fund's investments are subject to changes in their value from a number of factors. However, the Fund's investments must meet strict standards set by its Board of Trustees and special rules under Federal law for money market funds. Those requirements include maintaining high credit quality, a short average maturity and diversification of the Fund's investments among issuers. Those provisions are designed to help minimize credit risks, to reduce the effects of changes in prevailing interest rates and to reduce the effect on the Fund's portfolio of a default by any one issuer. Since income on short-term securities tends to be lower than income on longer-term debt securities, the Fund's yield will likely be lower than the yield on longer-term fixed-income funds.
Even so, there are risks that an issuer of an obligation that the Fund holds might have its credit rating downgraded or might default on its obligations, or that interest rates might rise sharply, causing the value of the Fund's investments to fall. Also, there is the risk that the value of your investment could be eroded over time by the effects of inflation, or that poor security selection could cause the Fund to underperform other funds that have a similar objective. If there is an unexpectedly high demand for the redemption of Fund shares, the Fund might need to sell portfolio securities prior to their maturity, possibly at a loss. As a result, there is a risk that the Fund's shares could fall below $1.00 per share.
Interest Rate Risk. The values of debt securities usually change when prevailing interest rates change. When interest rates fall, the values of already-issued debt securities generally rise. When interest rates rise, the values of already-issued debt securities generally fall. The values of longer-term debt securities usually change more when interest rates change than the values of shorter-term debt securities.
Credit Risk. Debt securities are also subject to credit risk, which is the risk that the issuer of a security might not make principal or interest payments on the security when they are due. If the issuer fails to pay interest, the Fund's income might be reduced, and if the issuer fails to pay interest or repay principal, the value of the security might 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 the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.
Main Risks of Foreign Investing. Although the risks of investing in foreign money market securities are significantly lower than the risks of certain other types of foreign securities, to the extent that the Fund invests in foreign securities, those investments may be 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 for the Fund to evaluate a foreign company's operations or financial condition. 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.
The rate of the Fund's income will vary from day to day, generally reflecting changes in short-term interest rates and in the fixed-income securities market. There is no assurance that the Fund will achieve its investment objective.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed for investors who want to earn income at money market rates while maintaining easy access to their investment and seeking to preserve its value. The Fund will invest in a variety of money market instruments to seek current income and stability of principal and to try to maintain a stable share price of $1.00. Since income on short-term securities tends to be lower than income on longer term debt securities, the Fund's yield will likely be lower than the yield on longer-term fixed income funds. The Fund does not invest for the purpose of seeking capital appreciation or gains and is not a complete investment program.
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. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

rr_PerformanceTableClosingTextBlock |
The average annual total returns measure the performance of a hypothetical account, without deducting charges imposed by the separate accounts that invest in the Fund, and assume that all dividends and capital gains distributions have been reinvested in additional shares.
The Fund's total returns should not be expected to be the same as the returns of other Oppenheimer funds, even if both funds have the same portfolio managers and/or similar names.
The total returns are not the Fund's current yield. The Fund's yield more closely reflects the Fund's current earnings.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies.
The Fund mainly invests in equity securities, such as common stocks of U.S. companies that the portfolio manager expects to have above-average growth rates. Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of "small-cap" and "mid-cap" companies. A company's "market capitalization" is the total value of its outstanding common stock. Relative to other companies, a company may be classified as small-cap, mid-cap or large-cap. The Fund defines small-cap and mid-cap companies as those companies that are within the range of market capitalizations of the Russell 2000® Growth Index and the Russell Midcap® Growth Index, respectively. This range is subject to change daily due to market activity and changes in the composition of those indices. The Fund measures a company's capitalization at the time the Fund buys a security, and it is not required to sell a security if the issuer's capitalization moves outside of the Fund's definition of small- and mid-cap issuers.
Under normal market conditions, the Fund can invest up to 20% of its net assets, plus borrowings for investment purposes, in stocks of companies in other market capitalizations, if the Manager believes they offer opportunities for growth.
The Fund invests primarily in U.S. companies but may also purchase securities of issuers in any country, including developed countries and emerging markets. The Fund has no limits on the amount of its assets that can be invested in foreign securities.
In selecting securities, the Fund's portfolio manager looks for companies with high growth potential using a "bottom-up" stock selection process. The "bottom-up" approach focuses on fundamental analysis of individual issuers before considering the impact of overall economic, market or industry trends. This approach includes analysis of a company's financial statements and management structure and consideration of the company's operations and product development, as well as its position in its industry. The portfolio manager looks for companies with revenues growing at above-average rates that might support and sustain above-average earnings. The portfolio manager also evaluates other business and economic factors, including cyclical factors, that might contribute to the company's stock appreciation. The Fund's portfolio manager currently focuses on companies with the following characteristics, which may vary in particular cases and may change over time:
-
An above-average rate of high quality growth that the portfolio manager believes is sustainable;
-
Experienced management teams with proven records;
-
Industry leaders with competitive advantages;
-
Companies with strong financials including low debt.
The Fund may not invest more than 25% of its total assets in any one industry, but in selecting securities it may, at times, invest more of its assets in issuers within a particular industry or economic or market sector. If so, its shares will be more sensitive to factors affecting that industry or sector.
The portfolio manager monitors individual issuers for changes in business fundamentals and valuation. If the portfolio manager notes a slowdown in the company's internal revenue growth or earnings growth or a negative movement in the company's fundamental economic condition, and if there are other investment alternatives that offer what he believes to be better appreciation possibilities, he may consider selling that stock.

|
| 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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.
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.
Sector Focus. Although the Fund will not invest more than 25% of its total assets in any one industry, it may from time to time invest a greater share of its assets in securities of companies in a particular economic or market sector. Some of those sectors, such as technology-related or healthcare-related securities, have historically experienced greater volatility than other sectors. To the extent that the Fund invests in companies in a particular market sector, it will be more vulnerable to the risks affecting that sector.
Who Is The Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. The Fund is designed primarily for investors seeking capital appreciation over the long term. 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 small- and mid-cap stock investments. Because of its focus on long-term growth, the Fund may be appropriate for investors with longer term investment goals. The Fund is not designed for investors needing current income. The Fund is not a complete investment program and may not be appropriate for all investors. 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.

| Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
Principal Investment Strategies. The Fund mainly invests in common stocks of companies that the portfolio manager believes are undervalued in the marketplace. They use fundamental analysis to seek companies whose intrinsic value is greater than the current price of their securities. A company's security may be undervalued because the market is not aware of the issuer's intrinsic value, does not yet recognize its future potential, or the issuer may be temporarily out of favor. The Fund may realize gains in the prices of those securities when other investors recognize their real or prospective worth. The portfolio manager's "bottom up" approach uses fundamental analysis to select securities one at a time, based on factors such as a company's long-term earnings and growth potential, before considering industry trends. The portfolio manager currently focus on companies with the following characteristics, which may vary in particular cases and may change over time:
-
Attractive valuation,
-
Future supply and demand conditions for its key products,
-
Product cycles,
-
Quality of management,
-
Competitive position in the market place,
-
Reinvestment plans for cash generated, and
-
Better-than-expected earnings reports.
The Fund may buy securities issued by companies of any size or market capitalization range and at times might increase its emphasis on securities of issuers in a particular capitalization range, including small- and mid-sized companies. While the Fund does not limit its investments to issuers in a particular capitalization range, the portfolio manager currently focuses on securities of larger-size companies.
The Fund may invest up to 25% of its total assets in securities of companies or governments in any foreign country, including both developed and emerging market countries. The Fund may also invest in other equity securities, such as preferred stock, rights, warrants and securities convertible into common stock and may invest up to 10% of its net assets in debt securities.
The portfolio manager may consider selling a stock, but are not required to, for one or more of the following reasons:
-
the stock price is approaching its price target,
-
the company's fundamentals are deteriorating, or
-
alternative investment ideas have been developed.

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 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 more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.
Main Risks of Investing in Stock. 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. 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 and a variety of factors can 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.
At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.
Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.
Main Risks of Value Investing. Value investing entails the risk that if the market does not recognize that the Fund's securities are undervalued, the prices of those securities might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause the Fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of "value" companies may underperform the securities of "growth" companies.
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 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 securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. 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. These risks may be greater for investments in developing or emerging market countries.
Time-Zone Arbitrage.
The Fund may invest in securities of foreign issuers that are traded in U.S. or foreign markets. If the Fund invests a significant amount of its assets in foreign markets, it may be exposed to "time-zone arbitrage" attempts by investors seeking to take advantage of differences in the values of foreign securities that might result from events that occur after the close of the foreign securities market on which a security is traded and before the Fund's net asset value is calculated. If such time-zone arbitrage were successful, it might dilute the interests of other shareholders. The Fund's use of "fair value pricing" to adjust certain market prices of foreign securities may help deter those activities.
Who Is the Fund Designed For? The Fund's shares are available only as an investment option under certain variable annuity contracts, variable life insurance policies and investment plans offered through insurance company separate accounts of participating insurance companies. Those investors should be willing to assume the risks of short-term share price fluctuations and losses that are typical for a fund emphasizing investments in stocks. Since the Fund's income level will fluctuate and will likely be small, it is not designed for investors needing an assured level of 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.
