| Risk [Text Block] | The following are the Principal Risks of the Fund. The value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund. Certain risks relating to instruments and strategies used in the management of the Fund are placed first. The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund.
|
| American Drive Moderate Allocation Portfolio | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Although stocks may have the potential to outperform other asset classes over the long term, their prices tend to fluctuate more dramatically over the shorter term. These movements may result from factors affecting individual companies, or from broader influences like changes in interest rates, market conditions, or investor confidence, or announcements of economic, political, or financial information.
|
| American Drive Moderate Allocation Portfolio | Fixedincome Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed-Income Securities Risk. The values of fixed-income securities typically will decline during periods of rising interest rates, and can also decline in response to changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral assets, or changes in market, economic, industry, political, regulatory, public health, and other conditions affecting a particular type of security or issuer or fixed-income securities generally. Certain events, such as market or economic developments, regulatory or government actions, natural disasters, pandemics, terrorist attacks, war, and other geopolitical events can have a dramatic, adverse effect on the debt market and the overall liquidity of the market for fixed-income securities. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, and potentially at unfavorable prices. Certain securities may be difficult to value during such periods. Fixed-income securities are subject to interest rate risk (the risk that the value of a fixed-income security will fall when interest rates rise), extension risk (the risk that the average life of a security will be extended through a slowing of principal payments), prepayment risk (the risk that a security will be prepaid and the Fund will be required to reinvest at a less favorable rate), duration risk (the risk that longer-term securities may be more sensitive to interest rate changes), inflation risk (the risk that as inflation increases, the present value of the Fund’s fixed-income investment typically will decline), and credit risk.

| American Drive Moderate Allocation Portfolio | Allocation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Allocation Risk. There is no assurance that allocation decisions regarding the Funds’ specific investments will result in the desired performance effects. There is a risk that the Adviser’s and Subadvisers’ evaluations and assumptions regarding asset classes may be incorrect in view of actual market conditions.
|
| American Drive Moderate Allocation Portfolio | Bank Loans Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Bank Loans Risk. Many of the risks associated with bank loans are similar to the risks of investing in below investment-grade debt securities. Changes in the financial condition of the borrower or economic conditions or other circumstances may reduce the capacity of the borrower to make principal and interest payments on such instruments and may lead to defaults. Senior secured bank loans are typically supported by collateral; however the value of the collateral may be insufficient to cover the amount owed to the Fund, or the Fund may be prevented or delayed from realizing on the collateral. Some loans may be unsecured; unsecured loans generally present a greater risk of loss to the Fund if the issuer defaults. If the Fund relies on a third party to administer a loan, the Fund is subject to the risk that the third party will fail to perform its obligations. In addition, if the Fund holds only a participation interest in a loan made by a third party, the Fund’s receipt of payments on the loan will depend on the third party’s willingness and ability to make those payments to the Fund. The settlement time for certain loans is longer than the settlement time for many other types of investments, and the Fund may not receive the payment for a loan sold by it until well after the sale; that cash would be unavailable for payment of redemption proceeds or for reinvestment. Interests in some bank loans may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what the Fund believes to be a fair price. Some loans may not be considered “securities” for certain purposes under the federal securities laws, and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.
|
| American Drive Moderate Allocation Portfolio | Below Investmentgrade Debt Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Below Investment-Grade Debt Securities Risk. Below investment-grade debt securities, commonly known as “junk” or “high-yield” bonds, have speculative characteristics and involve greater volatility of price and yield, greater risk of loss of principal and interest, and generally reflect a greater possibility of an adverse change in financial condition that could affect an issuer’s ability to honor its obligations.
|
| American Drive Moderate Allocation Portfolio | Cash Position Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Position Risk. If the Fund holds a significant portion of its assets in cash or cash equivalents, its investment returns may be adversely affected and the Fund may not achieve its investment objective.
|
| American Drive Moderate Allocation Portfolio | Collateralized Loan Obligations Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Collateralized Loan Obligations Risk. A Fund may invest in collateralized debt obligations (“CDOs”), including collateralized loan obligations (“CLOs”). CLOs and other CDOs are types of asset-backed securities. A CLO is typically an obligation of a trust backed (or collateralized) by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Other types of CDOs may include, by way of example, obligations of trusts backed by other types of assets representing obligations of various types, and may include high risk, below investment-grade debt obligations. CLOs and other CDOs may pay management fees and administrative expenses. The risk profile of an investment in CLO or other CDO depends largely on the type of the collateral securities and the class of the instrument in which a Fund invests.
|
| American Drive Moderate Allocation Portfolio | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. The Funds have a fundamental policy not to invest more than 25% of the current value of each Fund’s total assets in any one industry, except that this policy does not apply to: (i) investments in securities of other investment companies, (ii) investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or (iii) investments in repurchase agreements collateralized by U.S. government securities. However, the Funds reserve the right to concentrate their investments (i.e., invest 25% or more of their total assets in securities of issuers in a particular industry) to approximately the same extent that the S&P 500 Index (the “Index”) concentrates in a specific industry. To the extent that each Fund concentrates in a particular industry, it may be more susceptible to economic conditions and risks particular to that industry.
|
| American Drive Moderate Allocation Portfolio | Convertible Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk. Convertible securities are subject to the risks of both debt instruments and equity securities. The price of a convertible security may change in response to changes in price of the underlying equity security, the credit quality of the issuer, and interest rates. In general, the values of convertible securities tend to decline as interest rates rise and to rise when interest rates fall. A convertible security generally has less potential for gain or loss than the underlying equity security.
|
| American Drive Moderate Allocation Portfolio | Credit Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk. Credit risk is the risk that an issuer, guarantor, or liquidity provider of a fixed-income security held by the Fund may be unable or unwilling, or may be perceived (whether by market participants, ratings agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or to otherwise honor its obligations. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.
|
| American Drive Moderate Allocation Portfolio | Defaulted And Distressed Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Defaulted and Distressed Securities Risk. Because the issuer of such securities is in default and is likely to be in distressed financial condition, repayment of defaulted securities and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring, or in bankruptcy or insolvency proceedings) is uncertain. To the extent the Fund is invested in distressed securities, its ability to achieve current income for its shareholders may be diminished.
|
| American Drive Moderate Allocation Portfolio | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives can create investment leverage and involve counterparty credit risk. Losses from derivatives can be substantially greater than the derivatives’ original cost and can sometimes be unlimited. If the value of a derivative does not correlate well with the particular market or asset class the derivative is designed to provide exposure to, the derivative may not have the effect or benefit anticipated.
|
| American Drive Moderate Allocation Portfolio | Emerging Markets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. Investments in the securities of issuers located in or principally doing business in emerging markets are subject to heightened foreign investments risks and may experience rapid and extreme changes in value. Emerging market countries tend to have more volatile interest and currency exchange rates, less market regulation, and less developed and less stable economic, political and legal systems than those of more developed countries. There may be less publicly available and reliable information about issuers in emerging markets than is available about issuers in more developed markets. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems. Some emerging markets may have fixed or managed currencies that are not free-floating against the U.S. dollar. Certain of these currencies have experienced, and may experience in the future, substantial fluctuations or a steady devaluation relative to the U.S. dollar. Certain emerging markets are sometimes referred to as “frontier markets.” Frontier markets, the least advanced capital markets in the developing world, are subject to heightened emerging markets risks.
|
| American Drive Moderate Allocation Portfolio | Environmental Social And Governance Considerations [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Environmental, Social, and Governance Considerations. With respect to certain Funds, certain environmental, social, and governance (“ESG”) factors, either quantitative or qualitative, may be considered by a Fund’s subadviser(s) in making investment decisions for the Fund as part of the investment process to implement the Fund’s investment strategy in pursuit of its investment objective. For these Funds, ESG factors are only one of many considerations that a subadviser may evaluate for any potential issuer or investment. The extent to which any ESG factors will affect a subadviser’s decision to invest in an issuer, if at all, will vary and depend on the analysis and judgment of the subadviser. The incorporation of ESG factors may not work as the subadviser intended.
A Fund’s portfolio will not be solely based on ESG considerations, and therefore the issuers in which the Fund invests may not be considered ESG-focused companies. The incorporation of ESG factors into a Fund’s investment process does not mean that every investment or potential investment undergoes an ESG review, and a Fund’s investment adviser or subadviser may not consider or identify every ESG factor for every investment the Fund makes, particularly, for example, in cases where ESG-related data for a potential investment is unavailable.
|
| American Drive Moderate Allocation Portfolio | Foreign Investment Risk Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk; Currency Risk. Investments in securities of foreign issuers, securities of companies with significant foreign exposure, and foreign currencies can involve additional risks relating to market, industry, political, regulatory, public health, and other conditions. Political, social, diplomatic, and economic developments, U.S. and foreign government action, or threat thereof, such as the imposition of currency or capital blockages, controls, or tariffs, economic and trade sanctions or embargoes, security trading suspensions, entering or exiting trade or other intergovernmental agreements, or the expropriation or nationalization of assets in a particular country, can cause dramatic declines in certain or all securities with exposure to that country and other countries. Sanctions, or the threat of sanctions, may cause volatility in regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, which could have a negative effect on the performance of the Fund. In the event of nationalization, expropriation, confiscation, or other government action, intervention, or restriction, the Fund could lose its entire investment in a particular foreign issuer or country. There may be quotas or other limits on the ability of the Fund (or clients of the Fund’s investment adviser or subadviser) to invest or maintain investments in securities of issuers in certain countries. Enforcing legal rights can be more difficult, costly, and limited in certain foreign countries and with respect to certain types of investments, and can be particularly difficult against foreign governments. Because non-U.S. securities are normally denominated and traded in currencies other than the U.S. dollar, the value of the Fund’s assets may be affected favorably or unfavorably by changes in currency exchange rates, exchange control regulations, and restrictions or prohibitions on the repatriation of non-U.S. currencies. Income and gains with respect to investments in certain countries may be subject to withholding and other taxes. There may be less information publicly available about a non-U.S. company than about a U.S. company, and many non-U.S. companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S. The securities of some non-U.S. companies, especially those in emerging markets, are less liquid and at times more volatile than securities of comparable U.S. companies. Emerging markets securities are subject to greater risks than securities issued in developed foreign markets, including less liquidity, less stringent investor protection and disclosure standards, less reliable settlement practices, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, greater risk of new or inconsistent government treatment of or restrictions on issuers and instruments, and greater volatility in currency exchange rates, and are more susceptible to environmental problems. Non-U.S. transaction costs, such as brokerage commissions and custody costs, may be higher than in the United States. In addition, foreign markets can react differently to market, economic, industry, political, regulatory, geopolitical, public health, and other conditions than the U.S. market. The Fund may invest in foreign securities known as depositary receipts. Investments in depositary receipts are subject to the same risks as direct investment in foreign securities, which include market, political, currency, and regulatory risks.
|
| American Drive Moderate Allocation Portfolio | Growth Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Company Risk. The prices of growth securities are often highly sensitive to market fluctuations because of their heavy dependence on future earnings or cash flow expectations, and can be more volatile than the market in general.
|
| American Drive Moderate Allocation Portfolio | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund’s attempts at hedging and taking long and short positions in currencies may not be successful and could cause the Fund to lose money or fail to get the benefit of a gain on a hedged position. If expected changes to securities prices, interest rates, currency values, and exchange rates, or the creditworthiness of an issuer are not accurately predicted, the Fund could be in a worse position than if it had not entered into such transactions.
|
| American Drive Moderate Allocation Portfolio | Inflationlinked Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inflation-Linked Securities Risk. Such securities may change in value in response to actual or anticipated changes in inflation rates in a manner unanticipated by the Fund’s portfolio manager or investors generally. Inflation-linked securities are subject to fixed-income securities risks. When inflation is low, declining, or negative, the Fund’s performance could lag the performance of more conventional bond funds. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy (or expectations that such policies will change), and the Fund’s investments may not keep pace with inflation, which may result in losses to the Fund’s investors.
|
| American Drive Moderate Allocation Portfolio | Investment Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk. The returns from a certain investment style may be lower than the returns from the overall stock market. Growth stock prices frequently reflect projections of future earnings or revenues, and if earnings growth expectations are not met, their stock prices will likely fall, which may reduce the value of a Fund’s investment in those stocks. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).
|
| American Drive Moderate Allocation Portfolio | Large Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Company Risk. Large-capitalization stocks as a group could fall out of favor with the market, causing the Fund’s investments in large-capitalization stocks to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
|
| American Drive Moderate Allocation Portfolio | Leveraging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leveraging Risk. Instruments and transactions, including derivatives, dollar roll, and reverse repurchase agreement transactions, that create leverage may cause the value of an investment in the Fund to be more volatile, could result in larger losses than if they were not used, and tend to compound the effects of other risks.
|
| American Drive Moderate Allocation Portfolio | Liquidity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. Certain securities may be difficult (or impossible) to sell or certain positions may be difficult to close out at a desirable time and price, and the Fund may be required to hold an illiquid investment that is declining in value, or it may be required to sell certain illiquid investments at a price or time that is not advantageous in order to meet redemptions or other cash needs. Some securities may be subject to restrictions on resale. There can be no assurance that there will be a liquid market for instruments held by the Fund at any time. The Fund may not receive the proceeds from the sale of certain investments for an extended period.
|
| American Drive Moderate Allocation Portfolio | Management And Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management and Operational Risk. The Fund relies on the manager’s investment analysis and its selection of investments to achieve its investment objective, and the Fund is subject to the risk that the manager’s assessment of an investment is wrong. There can be no assurance that the Fund will achieve the intended results and the Fund may incur significant losses. The Fund also runs the risk that deficiencies in the Adviser’s, Subadviser’s, or another service provider’s internal systems or controls will cause losses for the Fund or impair Fund operations.
|
| American Drive Moderate Allocation Portfolio | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The value of the Fund’s portfolio securities may decline, at times sharply and unpredictably, as a result of unfavorable market-induced changes affecting particular industries, sectors, or issuers. Stock and bond markets can decline significantly in response to issuer, market, economic, industry, political, regulatory, geopolitical, public health, and other conditions, as well as investor perceptions of these conditions. The Fund is subject to risks affecting issuers, such as management performance, financial leverage, industry problems, and reduced demand for goods or services.
|
| American Drive Moderate Allocation Portfolio | Mortgage And Assetbacked Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage- and Asset-Backed Securities Risk. Investments in mortgage- and asset-backed securities subject the Fund to credit risk, interest rate risk, extension risk, and prepayment risk, among other risks. Mortgage-backed and asset backed securities not issued by a government agency generally involve greater credit risk than securities issued by government agencies. Payment of principal and interest generally depends on the cash flows generated by the underlying assets and the terms of the security. The types of mortgages (for example, residential or commercial mortgages) underlying securities held by the Fund may differ and be affected differently by market factors. The Fund’s investments in mortgage-backed securities may make the Fund’s net asset value more susceptible to economic, market, political, and other developments affecting the residential and commercial real estate markets and the servicing of mortgage loans secured by real estate properties. During periods of difficult economic conditions, delinquencies and losses on commercial mortgage-backed investments in particular generally increase, including as a result of the effects of those conditions on commercial real estate markets, the ability of commercial tenants to make loan payments, and the ability of a property to attract and retain commercial tenants. Investments that receive only the interest portion or the principal portion of payments on the underlying assets may be highly volatile. Litigation with respect to the representations and warranties given in connection with the issuance of mortgage-backed securities can be an important consideration in investing in such securities, and the outcome of any such litigation could significantly impact the value of the Fund’s mortgage-backed investments.
|
| American Drive Moderate Allocation Portfolio | Pooled Investments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Pooled Investments Risk. Investments in other investment companies or private investment vehicles expose the Fund indirectly to all of the risks applicable to any other investment company or pool in which it invests, including that the investment company or pool will not perform as expected. Investments in other investment companies or private pools may be illiquid, may be leveraged, and may be highly volatile. Investing in other investment companies or private investment vehicles sponsored or managed by the investment adviser or subadviser, as applicable, or affiliates of the investment adviser or subadviser, as applicable, involves potential conflicts of interest. For example, the investment adviser or subadviser, as applicable, or their affiliates may receive fees based on the amount of assets invested in such other investment vehicles, which fees may be higher than the fees the investment adviser or subadviser, as applicable, receives for managing the investing Fund. Investment by a Fund in those other vehicles may be beneficial in the management of those other vehicles, by helping to achieve economies of scale or enhancing cash flows. Due to this and other factors, the investment adviser or subadviser, as applicable, will have an incentive to invest a portion of a Fund’s assets in investment vehicles sponsored or managed by the investment adviser or subadviser, as applicable, or their affiliates in lieu of investments by the Fund directly in portfolio securities, and will have an incentive to invest in such investment vehicles over non-affiliated investment companies. The investment adviser or subadviser, as applicable, will have no obligation to select the least expensive or best performing funds available to serve as an underlying investment vehicle.
|
| American Drive Moderate Allocation Portfolio | Preferred Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, changes in interest rates may adversely affect the value of a preferred stock that pays a fixed dividend. Preferred stocks are also subject to additional risks, such as potentially greater volatility and risks related to deferral, non-cumulative dividends, subordination, liquidity, limited voting rights, and special redemption rights.
|
| American Drive Moderate Allocation Portfolio | Quantitative Models Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Models Risk. Certain portfolio managers use quantitative models as part of the idea generation process. Quantitative models are based upon many factors that measure individual securities relative to each other. Such models may not produce the intended results and can be adversely affected by errors or imperfections in the factors or the data on which measurements are based, changing sources of market return or market risk, human error, or any technical issues with or errors in the design, construction, implementation, or maintenance of the models.
|
| American Drive Moderate Allocation Portfolio | Reit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Risk. Investments in REITs may be subject to risks similar to those associated with direct investment in real estate, as well as additional risks associated with equity investments. As a shareholder in a REIT, the Fund, and indirectly the Fund’s shareholders, would bear its ratable share of the REIT’s expenses and would at the same time continue to pay its own fees and expenses.
|
| American Drive Moderate Allocation Portfolio | Restricted Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Restricted Securities Risk. The Fund may hold securities that are restricted as to resale under U.S. federal securities laws, such as securities in certain privately held companies. Such securities may be highly illiquid and their values may experience significant volatility. Restricted securities may be difficult to value.
|
| American Drive Moderate Allocation Portfolio | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. The Fund may allocate more of its assets to particular industries or to particular economic, market, or industry sectors than to others. This could increase the volatility of the Fund’s portfolio, and the Fund’s performance may be more susceptible to developments affecting issuers in those industries or sectors than if the Fund invested more broadly.
|
| American Drive Moderate Allocation Portfolio | Small And Midcap Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small- and Mid-Cap Company Risk. Market risk and liquidity risk are particularly pronounced for securities of small and medium-sized companies, which may trade less frequently and in smaller volumes than more widely-held securities, and may fluctuate in price more than other securities. Their shares can be less liquid than those of larger companies, especially during market declines. Small and medium-sized companies may have limited product lines, markets, or financial resources and may be dependent on a limited management group; they may have been recently organized and have little or no track record of success.
|
| American Drive Moderate Allocation Portfolio | Sovereign Debt Obligations Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sovereign Debt Obligations Risk. Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Many sovereign debt obligations may be rated below investment grade (“junk” or “high-yield” bonds). Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt.
|
| American Drive Moderate Allocation Portfolio | U S Government Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Securities Risk. Obligations of certain U.S. Government agencies and instrumentalities are not backed by the full faith and credit of the U.S. Government, and there can be no assurance that the U.S. Government would provide financial support to such agencies and instrumentalities.
|
| American Drive Moderate Allocation Portfolio | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk. The Fund is subject to the risk of mispricing or improper valuation of its investments, in particular to the extent that its securities are fair valued in connection with investments in international investment-grade corporate bonds, high yield corporate bonds (commonly referred to as “junk bonds”) and mortgages.
|
| American Drive Moderate Allocation Portfolio | Value Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Company Risk. The value investment approach entails the risk that the market will not recognize a security’s intrinsic value for a long time, or that a stock the Adviser or Subadviser judges to be undervalued may actually be appropriately priced.
|
| American Drive Moderate Allocation Portfolio | Whenissued Delayed Delivery Tba And Forward Commitment Transaction Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | When-Issued, Delayed Delivery, TBA, and Forward Commitment Transaction Risk. These transactions may create leverage and involve a risk of loss if the value of the securities declines prior to settlement. |
| American Drive Moderate Allocation Portfolio | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You can lose money by investing in the Fund. |
| American Drive Aggressive Allocation Portfolio | |
| Prospectus [Line Items] | |
| Risk [Text Block] | The following are the Principal Risks of the Fund. The value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund. Certain risks relating to instruments and strategies used in the management of the Fund are placed first. The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund.
|
| American Drive Aggressive Allocation Portfolio | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Although stocks may have the potential to outperform other asset classes over the long term, their prices tend to fluctuate more dramatically over the shorter term. These movements may result from factors affecting individual companies, or from broader influences like changes in interest rates, market conditions, or investor confidence, or announcements of economic, political, or financial information.
|
| American Drive Aggressive Allocation Portfolio | Fixedincome Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed-Income Securities Risk. The values of fixed-income securities typically will decline during periods of rising interest rates, and can also decline in response to changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral assets, or changes in market, economic, industry, political, regulatory, public health, and other conditions affecting a particular type of security or issuer or fixed-income securities generally. Certain events, such as market or economic developments, regulatory or government actions, natural disasters, pandemics, terrorist attacks, war, and other geopolitical events can have a dramatic, adverse effect on the debt market and the overall liquidity of the market for fixed-income securities. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, and potentially at unfavorable prices. Certain securities may be difficult to value during such periods. Fixed-income securities are subject to interest rate risk (the risk that the value of a fixed-income security will fall when interest rates rise), extension risk (the risk that the average life of a security will be extended through a slowing of principal payments), prepayment risk (the risk that a security will be prepaid and the Fund will be required to reinvest at a less favorable rate), duration risk (the risk that longer-term securities may be more sensitive to interest rate changes), inflation risk (the risk that as inflation increases, the present value of the Fund’s fixed-income investment typically will decline), and credit risk.
|
| American Drive Aggressive Allocation Portfolio | Allocation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Allocation Risk. There is no assurance that allocation decisions regarding the Funds’ specific investments will result in the desired performance effects. There is a risk that the Adviser’s and Subadvisers’ evaluations and assumptions regarding asset classes may be incorrect in view of actual market conditions.
|
| American Drive Aggressive Allocation Portfolio | Bank Loans Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Bank Loans Risk. Many of the risks associated with bank loans are similar to the risks of investing in below investment-grade debt securities. Changes in the financial condition of the borrower or economic conditions or other circumstances may reduce the capacity of the borrower to make principal and interest payments on such instruments and may lead to defaults. Senior secured bank loans are typically supported by collateral; however the value of the collateral may be insufficient to cover the amount owed to the Fund, or the Fund may be prevented or delayed from realizing on the collateral. Some loans may be unsecured; unsecured loans generally present a greater risk of loss to the Fund if the issuer defaults. If the Fund relies on a third party to administer a loan, the Fund is subject to the risk that the third party will fail to perform its obligations. In addition, if the Fund holds only a participation interest in a loan made by a third party, the Fund’s receipt of payments on the loan will depend on the third party’s willingness and ability to make those payments to the Fund. The settlement time for certain loans is longer than the settlement time for many other types of investments, and the Fund may not receive the payment for a loan sold by it until well after the sale; that cash would be unavailable for payment of redemption proceeds or for reinvestment. Interests in some bank loans may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what the Fund believes to be a fair price. Some loans may not be considered “securities” for certain purposes under the federal securities laws, and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

| American Drive Aggressive Allocation Portfolio | Below Investmentgrade Debt Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Below Investment-Grade Debt Securities Risk. Below investment-grade debt securities, commonly known as “junk” or “high yield” bonds, have speculative characteristics and involve greater volatility of price and yield, greater risk of loss of principal and interest, and generally reflect a greater possibility of an adverse change in financial condition that could affect an issuer’s ability to honor its obligations.
|
| American Drive Aggressive Allocation Portfolio | Cash Position Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash Position Risk. If the Fund holds a significant portion of its assets in cash or cash equivalents, its investment returns may be adversely affected and the Fund may not achieve its investment objective.
|
| American Drive Aggressive Allocation Portfolio | Collateralized Loan Obligations Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Collateralized Loan Obligations Risk. A Fund may invest in collateralized debt obligations (“CDOs”), including collateralized loan obligations (“CLOs”). CLOs and other CDOs are types of asset-backed securities. A CLO is typically an obligation of a trust backed (or collateralized) by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment-grade or equivalent unrated loans. Other types of CDOs may include, by way of example, obligations of trusts backed by other types of assets representing obligations of various types, and may include high risk, below investment-grade debt obligations. CLOs and other CDOs may pay management fees and administrative expenses. The risk profile of an investment in CLO or other CDO depends largely on the type of the collateral securities and the class of the instrument in which a Fund invests.
|
| American Drive Aggressive Allocation Portfolio | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. The Funds have a fundamental policy not to invest more than 25% of the current value of each Fund’s total assets in any one industry, except that this policy does not apply to: (i) investments in securities of other investment companies, (ii) investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or (iii) investments in repurchase agreements collateralized by U.S. government securities. However, the Funds reserve the right to concentrate their investments (i.e., invest 25% or more of their total assets in securities of issuers in a particular industry) to approximately the same extent that the S&P 500 Index (the “Index”) concentrates in a specific industry. To the extent that each Fund concentrates in a particular industry, it may be more susceptible to economic conditions and risks particular to that industry.
|
| American Drive Aggressive Allocation Portfolio | Convertible Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities Risk. Convertible securities are subject to the risks of both debt instruments and equity securities. The price of a convertible security may change in response to changes in price of the underlying equity security, the credit quality of the issuer, and interest rates. In general, the values of convertible securities tend to decline as interest rates rise and to rise when interest rates fall. A convertible security generally has less potential for gain or loss than the underlying equity security.
|
| American Drive Aggressive Allocation Portfolio | Credit Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk. Credit risk is the risk that an issuer, guarantor, or liquidity provider of a fixed-income security held by the Fund may be unable or unwilling, or may be perceived (whether by market participants, ratings agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or to otherwise honor its obligations. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.
|
| American Drive Aggressive Allocation Portfolio | Defaulted And Distressed Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Defaulted and Distressed Securities Risk. Because the issuer of such securities is in default and is likely to be in distressed financial condition, repayment of defaulted securities and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring, or in bankruptcy or insolvency proceedings) is uncertain. To the extent the Fund is invested in distressed securities, its ability to achieve current income for its shareholders may be diminished.
|
| American Drive Aggressive Allocation Portfolio | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. Derivatives can create investment leverage and involve counterparty credit risk. Losses from derivatives can be substantially greater than the derivatives’ original cost and can sometimes be unlimited. If the value of a derivative does not correlate well with the particular market or asset class the derivative is designed to provide exposure to, the derivative may not have the effect or benefit anticipated.
|
| American Drive Aggressive Allocation Portfolio | Emerging Markets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Markets Risk. Investments in the securities of issuers located in or principally doing business in emerging markets are subject to heightened foreign investments risks and may experience rapid and extreme changes in value. Emerging market countries tend to have more volatile interest and currency exchange rates, less market regulation, and less developed and less stable economic, political and legal systems than those of more developed countries. There may be less publicly available and reliable information about issuers in emerging markets than is available about issuers in more developed markets. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems. Some emerging markets may have fixed or managed currencies that are not free-floating against the U.S. dollar. Certain of these currencies have experienced, and may experience in the future, substantial fluctuations or a steady devaluation relative to the U.S. dollar. Certain emerging markets are sometimes referred to as “frontier markets.” Frontier markets, the least advanced capital markets in the developing world, are subject to heightened emerging markets risks.
|
| American Drive Aggressive Allocation Portfolio | Environmental Social And Governance Considerations [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Environmental, Social, and Governance Considerations. With respect to certain Funds, certain environmental, social, and governance (“ESG”) factors, either quantitative or qualitative, may be considered by a Fund’s subadviser(s) in making investment decisions for the Fund as part of the investment process to implement the Fund’s investment strategy in pursuit of its investment objective. For these Funds, ESG factors are only one of many considerations that a subadviser may evaluate for any potential issuer or investment. The extent to which any ESG factors will affect a subadviser’s decision to invest in an issuer, if at all, will vary and depend on the analysis and judgment of the subadviser. The incorporation of ESG factors may not work as the subadviser intended.
A Fund’s portfolio will not be solely based on ESG considerations, and therefore the issuers in which the Fund invests may not be considered ESG-focused companies. The incorporation of ESG factors into a Fund’s investment process does not mean that every investment or potential investment undergoes an ESG review, and a Fund’s investment adviser or subadviser may not consider or identify every ESG factor for every investment the Fund makes, particularly, for example, in cases where ESG-related data for a potential investment is unavailable.
|
| American Drive Aggressive Allocation Portfolio | Foreign Investment Risk Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk; Currency Risk. Investments in securities of foreign issuers, securities of companies with significant foreign exposure, and foreign currencies can involve additional risks relating to market, industry, political, regulatory, public health, and other conditions. Political, social, diplomatic, and economic developments, U.S. and foreign government action, or threat thereof, such as the imposition of currency or capital blockages, controls, or tariffs, economic and trade sanctions or embargoes, security trading suspensions, entering or exiting trade or other intergovernmental agreements, or the expropriation or nationalization of assets in a particular country, can cause dramatic declines in certain or all securities with exposure to that country and other countries. Sanctions, or the threat of sanctions, may cause volatility in regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, which could have a negative effect on the performance of the Fund. In the event of nationalization, expropriation, confiscation, or other government action, intervention, or restriction, the Fund could lose its entire investment in a particular foreign issuer or country. There may be quotas or other limits on the ability of the Fund (or clients of the Fund’s investment adviser or subadviser) to invest or maintain investments in securities of issuers in certain countries. Enforcing legal rights can be more difficult, costly, and limited in certain foreign countries and with respect to certain types of investments, and can be particularly difficult against foreign governments. Because non-U.S. securities are normally denominated and traded in currencies other than the U.S. dollar, the value of the Fund’s assets may be affected favorably or unfavorably by changes in currency exchange rates, exchange control regulations, and restrictions or prohibitions on the repatriation of non-U.S. currencies. Income and gains with respect to investments in certain countries may be subject to withholding and other taxes. There may be less information publicly available about a non-U.S. company than about a U.S. company, and many non-U.S. companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S. The securities of some non-U.S. companies, especially those in emerging markets, are less liquid and at times more volatile than securities of comparable U.S. companies. Emerging markets securities are subject to greater risks than securities issued in developed foreign markets, including less liquidity, less stringent investor protection and disclosure standards, less reliable settlement practices, greater price volatility, higher relative rates of inflation, greater political, economic, and social instability, greater custody and operational risks, greater risk of new or inconsistent government treatment of or restrictions on issuers and instruments, and greater volatility in currency exchange rates, and are more susceptible to environmental problems. Non-U.S. transaction costs, such as brokerage commissions and custody costs, may be higher than in the United States. In addition, foreign markets can react differently to market, economic, industry, political, regulatory, geopolitical, public health, and other conditions than the U.S. market. The Fund may invest in foreign securities known as depositary receipts. Investments in depositary receipts are subject to the same risks as direct investment in foreign securities, which include market, political, currency, and regulatory risks.
|
| American Drive Aggressive Allocation Portfolio | Growth Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Company Risk. The prices of growth securities are often highly sensitive to market fluctuations because of their heavy dependence on future earnings or cash flow expectations, and can be more volatile than the market in general.
|
| American Drive Aggressive Allocation Portfolio | Hedging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Risk. The Fund’s attempts at hedging and taking long and short positions in currencies may not be successful and could cause the Fund to lose money or fail to get the benefit of a gain on a hedged position. If expected changes to securities prices, interest rates, currency values, and exchange rates, or the creditworthiness of an issuer are not accurately predicted, the Fund could be in a worse position than if it had not entered into such transactions.
|
| American Drive Aggressive Allocation Portfolio | Inflationlinked Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Inflation-Linked Securities Risk. Such securities may change in value in response to actual or anticipated changes in inflation rates in a manner unanticipated by the Fund’s portfolio manager or investors generally. Inflation-linked securities are subject to fixed-income securities risks. When inflation is low, declining, or negative, the Fund’s performance could lag the performance of more conventional bond funds. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy (or expectations that such policies will change), and the Fund’s investments may not keep pace with inflation, which may result in losses to the Fund’s investors.
|
| American Drive Aggressive Allocation Portfolio | Investment Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk. The returns from a certain investment style may be lower than the returns from the overall stock market. Growth stock prices frequently reflect projections of future earnings or revenues, and if earnings growth expectations are not met, their stock prices will likely fall, which may reduce the value of a Fund’s investment in those stocks. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).
|
| American Drive Aggressive Allocation Portfolio | Large Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Company Risk. Large-capitalization stocks as a group could fall out of favor with the market, causing the Fund’s investments in large-capitalization stocks to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
|
| American Drive Aggressive Allocation Portfolio | Leveraging Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leveraging Risk. Instruments and transactions, including derivatives, dollar roll, and reverse repurchase agreement transactions, that create leverage may cause the value of an investment in the Fund to be more volatile, could result in larger losses than if they were not used, and tend to compound the effects of other risks.
|
| American Drive Aggressive Allocation Portfolio | Liquidity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. Certain securities may be difficult (or impossible) to sell or certain positions may be difficult to close out at a desirable time and price, and the Fund may be required to hold an illiquid investment that is declining in value, or it may be required to sell certain illiquid investments at a price or time that is not advantageous in order to meet redemptions or other cash needs. Some securities may be subject to restrictions on resale. There can be no assurance that there will be a liquid market for instruments held by the Fund at any time. The Fund may not receive the proceeds from the sale of certain investments for an extended period.
|
| American Drive Aggressive Allocation Portfolio | Management And Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management and Operational Risk. The Fund relies on the manager’s investment analysis and its selection of investments to achieve its investment objective, and the Fund is subject to the risk that the manager’s assessment of an investment is wrong. There can be no assurance that the Fund will achieve the intended results and the Fund may incur significant losses. The Fund also runs the risk that deficiencies in the Adviser’s, Subadviser’s, or another service provider’s internal systems or controls will cause losses for the Fund or impair Fund operations.
|
| American Drive Aggressive Allocation Portfolio | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The value of the Fund’s portfolio securities may decline, at times sharply and unpredictably, as a result of unfavorable market-induced changes affecting particular industries, sectors, or issuers. Stock and bond markets can decline significantly in response to issuer, market, economic, industry, political, regulatory, geopolitical, public health, and other conditions, as well as investor perceptions of these conditions. The Fund is subject to risks affecting issuers, such as management performance, financial leverage, industry problems, and reduced demand for goods or services.
|
| American Drive Aggressive Allocation Portfolio | Mortgage And Assetbacked Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mortgage- and Asset-Backed Securities Risk. Investments in mortgage- and asset-backed securities subject the Fund to credit risk, interest rate risk, extension risk, and prepayment risk, among other risks. Mortgage-backed and asset backed securities not issued by a government agency generally involve greater credit risk than securities issued by government agencies. Payment of principal and interest generally depends on the cash flows generated by the underlying assets and the terms of the security. The types of mortgages (for example, residential or commercial mortgages) underlying securities held by the Fund may differ and be affected differently by market factors. The Fund’s investments in mortgage-backed securities may make the Fund’s net asset value more susceptible to economic, market, political, and other developments affecting the residential and commercial real estate markets and the servicing of mortgage loans secured by real estate properties. During periods of difficult economic conditions, delinquencies and losses on commercial mortgage-backed investments in particular generally increase, including as a result of the effects of those conditions on commercial real estate markets, the ability of commercial tenants to make loan payments, and the ability of a property to attract and retain commercial tenants. Investments that receive only the interest portion or the principal portion of payments on the underlying assets may be highly volatile. Litigation with respect to the representations and warranties given in connection with the issuance of mortgage-backed securities can be an important consideration in investing in such securities, and the outcome of any such litigation could significantly impact the value of the Fund’s mortgage-backed investments.
|
| American Drive Aggressive Allocation Portfolio | Pooled Investments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Pooled Investments Risk. Investments in other investment companies or private investment vehicles expose the Fund indirectly to all of the risks applicable to any other investment company or pool in which it invests, including that the investment company or pool will not perform as expected. Investments in other investment companies or private pools may be illiquid, may be leveraged, and may be highly volatile. Investing in other investment companies or private investment vehicles sponsored or managed by the investment adviser or subadviser, as applicable, or affiliates of the investment adviser or subadviser, as applicable, involves potential conflicts of interest. For example, the investment adviser or subadviser, as applicable, or their affiliates may receive fees based on the amount of assets invested in such other investment vehicles, which fees may be higher than the fees the investment adviser or subadviser, as applicable, receives for managing the investing Fund. Investment by a Fund in those other vehicles may be beneficial in the management of those other vehicles, by helping to achieve economies of scale or enhancing cash flows. Due to this and other factors, the investment adviser or subadviser, as applicable, will have an incentive to invest a portion of a Fund’s assets in investment vehicles sponsored or managed by the investment adviser or subadviser, as applicable, or their affiliates in lieu of investments by the Fund directly in portfolio securities, and will have an incentive to invest in such investment vehicles over non-affiliated investment companies. The investment adviser or subadviser, as applicable, will have no obligation to select the least expensive or best performing funds available to serve as an underlying investment vehicle.
|
| American Drive Aggressive Allocation Portfolio | Preferred Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk. Like other equity securities, preferred stock is subject to the risk that its value may decrease based on actual or perceived changes in the business or financial condition of the issuer. In addition, changes in interest rates may adversely affect the value of a preferred stock that pays a fixed dividend. Preferred stocks are also subject to additional risks, such as potentially greater volatility and risks related to deferral, non-cumulative dividends, subordination, liquidity, limited voting rights, and special redemption rights.
|
| American Drive Aggressive Allocation Portfolio | Quantitative Models Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Models Risk. Certain portfolio managers use quantitative models as part of the idea generation process. Quantitative models are based upon many factors that measure individual securities relative to each other. Such models may not produce the intended results and can be adversely affected by errors or imperfections in the factors or the data on which measurements are based, changing sources of market return or market risk, human error, or any technical issues with or errors in the design, construction, implementation, or maintenance of the models.
|
| American Drive Aggressive Allocation Portfolio | Reit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REIT Risk. Investments in REITs may be subject to risks similar to those associated with direct investment in real estate, as well as additional risks associated with equity investments. As a shareholder in a REIT, the Fund, and indirectly the Fund’s shareholders, would bear its ratable share of the REIT’s expenses and would at the same time continue to pay its own fees and expenses.
|
| American Drive Aggressive Allocation Portfolio | Restricted Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Restricted Securities Risk. The Fund may hold securities that are restricted as to resale under U.S. federal securities laws, such as securities in certain privately held companies. Such securities may be highly illiquid and their values may experience significant volatility. Restricted securities may be difficult to value.
|
| American Drive Aggressive Allocation Portfolio | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. The Fund may allocate more of its assets to particular industries or to particular economic, market, or industry sectors than to others. This could increase the volatility of the Fund’s portfolio, and the Fund’s performance may be more susceptible to developments affecting issuers in those industries or sectors than if the Fund invested more broadly.
|
| American Drive Aggressive Allocation Portfolio | Small And Midcap Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small and Mid-Cap Company Risk. Market risk and liquidity risk are particularly pronounced for securities of small and medium-sized companies, which may trade less frequently and in smaller volumes than more widely-held securities, and may fluctuate in price more than other securities. Their shares can be less liquid than those of larger companies, especially during market declines. Small and medium-sized companies may have limited product lines, markets, or financial resources and may be dependent on a limited management group; they may have been recently organized and have little or no track record of success.
|
| American Drive Aggressive Allocation Portfolio | Sovereign Debt Obligations Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sovereign Debt Obligations Risk. Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Many sovereign debt obligations may be rated below investment grade (“junk” or “high-yield” bonds). Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt.
|
| American Drive Aggressive Allocation Portfolio | U S Government Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Securities Risk. Obligations of certain U.S. Government agencies and instrumentalities are not backed by the full faith and credit of the U.S. Government, and there can be no assurance that the U.S. Government would provide financial support to such agencies and instrumentalities.
|
| American Drive Aggressive Allocation Portfolio | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk. The Fund is subject to the risk of mispricing or improper valuation of its investments, in particular to the extent that its securities are fair valued in connection with investments in international investment-grade corporate bonds, high yield corporate bonds (commonly referred to as “junk bonds”) and mortgages.
|
| American Drive Aggressive Allocation Portfolio | Value Company Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Company Risk. The value investment approach entails the risk that the market will not recognize a security’s intrinsic value for a long time, or that a stock the Adviser or Subadviser judges to be undervalued may actually be appropriately priced.
