This table describes the annual operating expenses that you may indirectly pay if you invest in the Portfolio through your retirement plan or if you allocate your insurance contract premiums or payments to the Portfolio. However, each insurance contract and separate account involves fees and expenses that are not described in this Prospectus. If the fees and expenses of your insurance contract or separate account were included in this table, your overall expenses would be higher. You should review the insurance contract prospectus for a complete description of fees and expenses

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual Portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal period, the Portfolio’s portfolio turnover rate was 2% of the average value of its portfolio.

Expense Example by, Year, Caption [Text] rr_ExpenseExampleByYearCaption The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. You would pay the same expenses if you did not redeem your shares. However, each insurance contract and separate account involves fees and expenses that are not included in the Example. If these fees and expenses were included in the Example, your overall expenses would be higher. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies:
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Portfolio’s adviser seeks to achieve the Portfolio’s investment objective by allocating assets among securities that represent seven broad asset classes and twelve subcategories using the adviser’s 7TwelveTM asset allocation model (the “7TwelveTM Model”). The adviser usually does not select individual stocks and bonds, but instead selects exchange-traded funds (“ETFs”) or mutual funds (together, “underlying funds”) that each invest primarily in securities representing one of the 12 subcategories of assets selected under the 7TwelveTM Model. The Portfolio may invest in underlying funds that hold securities from issuers of any market capitalization, credit quality, maturity, country, or trading currency. However, bond credit quality will be primarily investment grade (that is, rated Baa3 or higher by Moody’s Investors Service, or equivalently rated by another nationally recognized statistical rating organization). The Portfolio may also buy underlying funds that invest in foreign securities traded on exchanges outside the U.S. and through American depositary receipts (“ADRs”). Under normal market conditions, the Portfolio invests at least 25% of its assets in equity securities (common stocks) and at least 25% of its assets in bonds. For purposes of meeting these 25% allocations, the Portfolio defines equity securities to include underlying funds that invest primarily in equity securities and defines bonds to include underlying funds that invest primarily in bonds and other fixed income securities.

 

Unlike traditional diversification strategies that rely primarily on two asset classes (stocks and bonds) in what is commonly known as a traditional balanced portfolio strategy, the 7TwelveTM Model utilizes multiple asset classes to enhance performance and reduce risk as measured by return volatility. The complete set of asset classes and subcategories utilized under the 7TwelveTM Model are presented in the table below.

 

 

Assets are initially allocated approximately equally using the 7TwelveTM Model, meaning that each subcategory represents 1/12th of the portfolio. This allocation is maintained by rebalancing the portfolio back to approximately equal portions monthly, quarterly or annually depending on the size of the deviation caused by changes in market value. The adviser buys and sells securities to rebalance asset class allocations as determined under its 7TwelveTM Model and also sells specific underlying funds when it believes it can be replaced by an underlying fund with greater liquidity, lower expenses or other features that make it an attractive replacement for an existing ETF.

Risk [Heading] rr_RiskHeading Principal Investment Risks:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Portfolio. The Portfolio is not intended to be a complete investment program. Many factors affect the Portfolio’s net asset value and performance.

 

The following risks apply to the Portfolio through its investments in underlying funds.

 

• Commodity Risk: Investing in the commodities markets through commodity-linked ETFs will subject the Portfolio to potentially greater volatility than traditional securities. Commodity prices are influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or production restrictions.

 

• Credit Risk: Security issuers might not make payments on debt securities held by the Portfolio, resulting in losses. Credit quality of securities held by the Portfolio may be lowered if an issuer’s financial condition changes.

 

• Duration Risk: Longer-term securities may be more sensitive to interest rate changes. Given the recent, historically low interest rates and the potential for increases in those rates, a heightened risk is posed by rising interest rates to a fund whose portfolios include longer-term fixed income securities.

 

• Emerging Markets Risk: In addition to the risks generally associated with nvesting in securities of foreign companies, countries with emerging markets also may have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.

 

• ETF Investment Risk: ETFs are subject to investment advisory fees and other expenses, which will be indirectly paid by the Portfolio. As a result, the cost of investing in the Portfolio will be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Index-based ETFs in which the Portfolio invests will not be able to replicate exactly the performance of the indices they track and the market value of ETF shares may differ from their net asset value. Each ETF is subject to specific risks, depending on the nature of the ETF. ETF shares may trade at a discount or premium to their NAV.

 

• Fixed Income Risk: The value of the Portfolio’s investments in bonds and other fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities. Recently, interest rates have been historically low. Current conditions may result in a rise in interest rates, which in turn may result in a decline in the value of the fixed income investments held by the Portfolio. As a result, for the present, interest rate risk may be heightened.

 

• Foreign Currency Risk: Foreign securities denominated in non-U.S. dollar currencies will subject the Portfolio to currency trading risks that include market risk and country risk. Market risk results from adverse changes in exchange rates. Country risk arises because a government may interfere with transactions in its currency.

 

• Foreign Investment Risk: Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing auditing and legal standards.

 

• Inflation Protected Securities Risk: Increases in real interest rates can cause the price of inflation-protected debt securities to decrease. Interest payments on inflation-protected debt securities can be unpredictable.

 

• Liquidity Risk: Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Portfolio’s returns because the Portfolio may be unable to transact at advantageous times or prices. Recently, interest rates have been historically low. Current conditions may result in a rise in interest rates, and a potential rise in interest rates may result in periods of volatility and increased redemptions. As a result of increased redemptions, the Portfolio may have to liquidate portfolio securities at disadvantageous prices and times, which could reduce the returns of the Portfolio. The reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years also has the potential to decrease liquidity.

 

• Management Risk: The adviser’s dependence on the 7TwelveTM Model strategy and judgments about the attractiveness, value and potential appreciation of particular asset classes and securities in which the Portfolio invests may prove to be incorrect and may not produce the desired results.

 

• Market Risk: Overall securities market risks may affect the value of individual ETFs in which the Portfolio invests. Factors such as foreign and domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets.

 

• Natural Resource Risk: The Portfolio’s exposure to companies primarily engaged in the natural resource markets may subject the Portfolio to greater volatility than the securities market as a whole. Natural resource companies are affected by commodity price volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs, and international economic, political and regulatory developments.

 

• Real Estate Risk: Real estate values rise and fall in response to a variety of factors, including local, regional and national economic conditions, interest rates and tax considerations. A real estate investment trust’s (“REIT”) performance depends on the types and locations of the rental properties it owns and on how well it manages those properties.

 

• Small and Medium Capitalization Stock Risk: The value of a small or medium capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

 

• Underlying Funds Risk: Underlying funds are subject to investment advisory fees and other expenses, which will be indirectly paid by the Portfolio. As a result, the cost of investing in the Portfolio will be higher than the cost of investing directly in other investment companies and may be higher than other mutual funds that invest directly in stocks and bonds. The ETFs in which the Portfolio invests will not be able to replicate exactly the performance of the indices they track and the market value of ETF shares may differ from their net asset value. Each underlying fund is subject to specific risks, depending on the nature of the fund.
