Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its assets in fixed income securities and/or investments that provide exposure to fixed income securities. Investments in fixed income securities may include, but are not limited to, debt securities of governments and government agencies throughout the world (including the United States), their agencies and instrumentalities and supranational organizations, municipal and local/provincial debt, debt securities of corporations, commercial paper, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities, inverse floater securities, interest‑only and principal‑only securities, equipment trusts, other securitized or collateralized debt obligations, and cash equivalents.

The Fund seeks to achieve its investment objective by investing primarily in fixed and floating rate debt securities, debt obligations of governments, government-related or corporate issuers worldwide and/or investments that provide exposure to fixed income securities. The Fund also regularly enters into currency-related transactions in both developed and emerging markets, in an attempt to generate total return and manage risk from differences in global short-term interest rates. The Fund may invest in securities or structured products that are linked to or derive their value from another security, index or asset (derivative investments). The Fund may enter into various currency‑related transactions involving derivative instruments, including currency and cross-currency forwards, currency and cross-currency swaps, currency and currency index futures contracts, and currency options. In addition, the Fund’s assets will be, under normal circumstances, invested in issuers located in or denominated in at least three countries (including the United States) and the Fund may invest a substantial portion (up to 75%) of its assets in emerging markets.

The Fund’s investments in fixed income securities may have all types of interest rate payment and reset terms, including fixed rate, adjustable rate, zero coupon, pay-in-kind and auction rate features. In addition, the fixed income securities and related instruments purchased by the Fund may be denominated in any currency, have coupons payable in any currency and may be of any maturity or duration. The average maturity of fixed income securities and related instruments in the Fund’s portfolio will fluctuate depending on the sub‑advisors’ outlook on changing market, economic, and political conditions. Additionally, the average duration of the Fund will be a combination not only of the duration of the debt securities in the Fund but also the presence of fixed income derivatives, as discussed below. The Fund may utilize fixed income derivatives to lower or extend the Fund’s duration substantially. The Fund may invest in fixed income securities of any credit quality, including below investment grade or high yield securities (sometimes referred to as “junk bonds”), and may buy bonds that are in default. It is anticipated that the Fund will frequently hold a substantial position in high yield securities.

The Fund may obtain a significant portion of its investment exposure through the use of derivatives, such as futures, forwards, options, swaps (including, among others, interest rate and credit default swaps) and credit derivatives. The Fund intends to use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Fund, to replace more traditional direct investments, or to obtain exposure to certain markets. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, durations or credit risks. The sub-advisors consider various factors, such as availability and cost, in deciding whether, when and to what extent to enter into derivative transactions. At times, the unconstrained investment approach may lead the Fund to have sizable allocations to particular markets, sectors and industries, and to have a sizable exposure to certain economic factors, such as credit risk, currency risk or interest rate risk. The Fund may, at times, maintain a large position in cash and cash equivalents (including money market funds).

The Fund’s portfolio is constructed by one or more sub-advisors. Each sub-advisor uses its own proprietary research and securities selection process to manage its allocated portion of the Fund’s assets. From time to time the Fund may have little or no assets allocated to a particular sub-advisor as determined by the Advisor in its sole discretion.

The sub-advisors allocate the Fund’s assets based upon their assessments of changing market, political and economic conditions. Each sub-advisor will consider various factors, including evaluation of interest and currency exchange rate changes and credit risks and may also consider the potential impacts of material environmental, social and governance factors on the long-term risk and return profile of a country. The sub-advisors have substantial latitude to invest across broad fixed income, derivative and currency markets. The unconstrained investment approach may lead the sub-advisors to have sizable allocations to particular markets, sectors and industries, and sizable exposures to those various factors.

The Fund’s currency exposure will be actively managed and the sub‑advisors will attempt to generate total returns and manage risk by identifying relative valuation discrepancies among global currencies as well as implementing hedging strategies to limit unwanted currency risks. These decisions are integrated within the macroeconomic framework analysis of global market and economic conditions.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Management Risk: An investment or allocation strategy used by the Advisor or a sub-advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the currency, equity and fixed income markets as well as the financial condition and prospects of companies or issuers in which the Fund invests.

Foreign Securities Risk: The risks of investing in foreign securities (including ADRs and GDRs) can increase the potential for losses in the Fund and may include currency fluctuations, political and economic instability, less government regulation, less publicly available information, limited trading markets, differences in financial reporting standards, fewer protections for passive investors and less stringent regulation of securities markets.

Emerging Markets Risk: In addition to the risks generally associated with investing in foreign securities described above, countries with emerging markets may also have relatively unstable governments, fewer shareholder protections, and more limited economies and securities markets. Additionally, trading in the currencies of emerging market countries may face periods of limited liquidity or the political risk of exchange controls or currency repatriation restrictions.

Foreign Exchange Trading Risk: The trading of foreign currencies directly generates risks separate from those faced from the risks of inactive or indirect exposures to non-dollar denominated instruments, insofar as the Fund may experience a loss from the buying and selling of currencies without any related exposure to non-dollar-denominated assets.

Interest Rate Risk: The market value of fixed income securities will fluctuate with changes in interest rates. For example, when interest rates rise, the market value of fixed income securities declines. If the market value of the Fund’s investments decreases, investors in the Fund may lose money.

Inflation-Indexed Securities Risk: Inflation-indexed securities have a tendency to react to changes in real interest rates. Real interest rates represent nominal (stated) interest rates lowered by the anticipated effect of inflation. In general, the price of an inflation-indexed security can decrease when real interest rates increase, and can increase when real interest rates decrease. Interest payments on inflation-indexed securities will fluctuate as the principal and/or interest is adjusted for inflation and can be unpredictable.

Loan Risk: Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take significantly longer than 7 days for investments in loans to settle, which can adversely affect the Fund’s ability to timely honor redemptions.

High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO. Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments. In addition, the purchase of debt securities which have previously fallen from investment grade to sub-investment grade status – and in particular the purchase of such instruments that have already been declared in default as to either income or principal – is particularly speculative and may lead to a loss of Fund value.

Mortgage- and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are subject to prepayment risk, which is the risk that the borrower will prepay some or all of the principal owed to the issuer. If that happens, the Fund may have to replace the security by investing the proceeds in a less attractive security.

Convertible Securities Risk: The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue. For example, with currency derivatives, there may be an imperfect correlation between a Fund’s portfolio holdings of securities denominated in a particular currency and the currencies underlying the currency derivatives entered into by the Fund.

Changing Fixed Income Market Conditions: Following the financial crisis that began in 2007, the Board of Governors of the Federal Reserve System (the “Federal Reserve”) attempted to support the U.S. economic recovery by keeping the federal funds rate at a low level. The Federal Reserve has begun raising the federal funds rate and may continue to do so. Further increases in the federal funds rate may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. If the Fund invests in derivatives tied to fixed-income markets, the Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives. To the extent the Fund experiences high redemptions because of these policy changes, the Fund may experience increased portfolio turnover, which will increase the costs the Fund incurs and may lower its performance. In addition, decreases in fixed income dealer market-making capacity may persist in the future, potentially leading to decreased liquidity and increased volatility in the fixed income markets.

Extension Risk: If interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

Credit Risk: Individual issues of fixed income securities may be subject to the credit risk of the issuer. This means that the issuer of a fixed income security, or in the case of a municipal security, the underlying municipality, may experience financial problems, causing it to be unable to meet its payment obligations.

Tax Risk – Inflation-Indexed Securities: Any increase in the principal amount of an inflation-indexed security may be included for tax purposes in the Fund’s gross income, even though no cash attributable to such gross income has been received by the Fund. In such event, the Fund may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Fund may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Fund and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Fund may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

Money Market Funds Risk. Although money market funds generally seek to preserve the value of an investment at $1.00 per share, the Fund may lose money by investing in money market funds. A money market fund’s sponsor has no legal obligation to provide financial support to the money market fund. The credit quality of a money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the money market fund's share price. A money market fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets and/or significant market volatility.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security. The Fund may, from time to time, take concentrated positions in positions that may be susceptible to a sudden loss of liquidity, such as private placements, structured notes, collateralized debt obligations, collateralized loan obligations, bank loans, over-the-counter derivative contracts and other similar instruments.

Maturity Risk: The Fund generally invests in municipal securities with intermediate- to long-term maturities. Generally, the longer a security’s maturity, the greater the risk that interest rate fluctuations may adversely affect the value of the security.

Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” The Advisor believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, among various asset classes, including domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and domestic and international fixed income securities. The intention is to capture broad capital market returns, while seeking to balance the pursuit of maximum total return against the control of total risk in the portfolio.

In addition to the general allocation into equity, fixed income and cash equivalent asset classes, the Fund’s assets are also typically allocated among a variety of sub-asset classes. The Fund’s equity investments typically include, either directly or indirectly via the Underlying Funds, a mix of weightings of larger and smaller capitalization equity securities, growth and value stocks, and equity securities from developed and emerging international markets. The Fund’s fixed income investments may be expected to be allocated, either directly or indirectly via the Underlying Funds, among corporate bonds, mortgage-backed or asset-backed securities, securities issued by the U.S. and foreign governments or their agencies and instrumentalities, and to higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. Typically, a significant portion of the Fund’s fixed income allocation will be in non-investment grade fixed income investments with varying maturities.

The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to generally remain consistent for longer periods of time. Under normal circumstances, the Fund is expected to allocate between 65% and 100% of its assets to equity securities or investments that provide exposure to equity securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions. Under normal market conditions, the Fund is expected to allocate approximately 99% of its assets to equity securities or investments that provide exposure to equity securities and 1% of its assets to fixed income securities or investments that provide exposure to fixed income securities, including cash equivalents. The Fund also may allocate significant assets to international equity markets: up to 45% to developed international markets and up to 35% to emerging markets.

The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to enhance returns, to manage or adjust the risk profile of the Underlying Fund, to replace more traditional direct investments, or to obtain exposure to certain markets.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investments in Underlying Funds. The following risks could affect the value of your investment in the Fund:

Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives. There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity and fixed income markets as well as the financial condition and prospects of companies in which the Fund invests.

Exchange-Traded Funds Risk: An ETF may represent a portfolio of securities, or may use derivatives in pursuit of its stated objective. The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.

Value Investment Risk: The Fund’s investments in value-oriented securities may be out of favor and potentially undervalued in the marketplace due to adverse business, industry or other developments. The Fund’s investments in value-oriented securities may not reach what the Fund’s Advisor believes are their full value.

Growth Investment Risk: The Fund’s investments in growth-oriented securities may be subject to greater price volatility and may be more sensitive to changes in the issuer’s current or expected earnings than other equity securities.

Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans and individual retirement accounts because such accounts are only subject to taxes upon withdrawal. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. These costs, which are not reflected in 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 69.19% of the average value of its portfolio.

The Example assumes that you invest $10,000 in Service Shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year, and that the Fund’s operating expenses remain the same. The Example reflects adjustments made to the Fund’s operating expenses due to the fee waiver and/or expense assumption by the Advisor for the 1-year number only.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, into a diversified portfolio consisting of domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and domestic and international fixed income securities. The intention is to capture broad capital market returns over the long term, while seeking to balance the pursuit of maximum total return against the control of risk in the portfolio.

In addition to the general strategic allocation into equity, fixed income and cash equivalent asset classes, the Fund’s assets are also typically allocated among a variety of sub-asset classes. The Fund’s equity investments typically include, either directly or indirectly via the Underlying Funds, a mix of weightings of larger and smaller capitalization equity securities, growth and value stocks, and equity securities from developed and emerging international markets. The Fund’s fixed income investments may be expected to be allocated, either directly or indirectly via the Underlying Funds, among corporate bonds, mortgage-backed or asset-backed securities, securities issued by the U.S. and foreign governments or their agencies and instrumentalities, and to higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. A significant portion of the Fund’s fixed income allocation may be in non-investment grade fixed income investments with varying maturities.

The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio.

Under normal circumstances, the Fund is expected to allocate between 15% and 55% of its assets to equity securities and investments that provide exposure to equity securities and between 45% and 85% of its assets to fixed income securities and investments that provide exposure to fixed income securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions or short-term market opportunities. Under normal market conditions, the Fund is expected to allocate approximately 35% of its assets to equity securities and investments that provide exposure to equity securities and 65% of its assets to fixed income securities and investments that provide exposure to fixed income securities, including cash equivalents. For example, if the Advisor believes that the stock market is undervalued, it may increase the equity allocation, or if the Advisor believes that the stock market is overvalued, it may decrease the equity allocation. Within these ranges, the Advisor has the ability to overweight or underweight certain asset classes in pursuit of increased return or reduced risk in the short to intermediate term. The Fund’s portfolio will be rebalanced periodically as a result of asset class performance causing drift away from the targeted asset allocation mix.

The Fund may invest in Underlying Funds that use derivatives to earn income and enhance returns, to manage or adjust their risk profile, to replace more traditional direct investments, or to obtain exposure to certain markets.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange–traded notes (“ETNs”).

In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, into a diversified portfolio consisting of domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)), domestic and international fixed income securities and cash equivalent money market securities.

The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include growth and value stocks, equity securities from developed and emerging international markets, commodity-related securities and domestic and international real estate securities, corporate bonds, mortgage-backed or asset-backed securities, securities issued by the U.S. and foreign governments or their agencies and instrumentalities, and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. A significant portion of the Fund’s fixed income allocation may be in non-investment grade fixed income investments with varying maturities, but these allocations may vary significantly over time.

The Fund may allocate assets to passive index-oriented ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.

The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from tactical volatility managed asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio.

The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to change frequently over time. The Fund does not have a set target asset allocation mix among equities, fixed income securities and cash equivalent investments. If the Advisor believes that the stock market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes such as fixed income or cash equivalent securities. The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investment in Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Alternative Strategies Risk: Certain Underlying Funds that use alternative investment strategies may be subject to risks including, but not limited to, derivatives risk, liquidity risk, credit risk and commodities risk. Certain alternative strategies involve the risk that a counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Leveraged and Inverse ETF/ETN Risk: Inverse ETFs/ETNs generally use derivatives and short sales that, in combination, are designed to produce returns that move in the opposite direction of the indices they track. To the extent the Fund invests in ETFs/ETNs that seek to provide investment results that are the inverse of the performance of an underlying index, the Fund will indirectly be subject to the risk that the performance of such ETF/ETN will fall as the performance of that ETF or ETN’s benchmark rises, a result that is the opposite from traditional mutual funds. The Fund’s use of leveraged and inverse-leveraged ETFs and ETNs has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in these instruments at all.

Commodities Risk: The Fund’s investment in commodity-linked investments and other commodity/natural resource-related securities may subject the Fund to greater volatility than investments in traditional securities. Commodity-linked investments may have a substantial risk of loss with respect to both principal and interest, and their returns may deviate significantly from the return of the underlying commodity, instruments, or measures. The ability of the Fund to invest in commodity-linked investments without exposing the Fund to Fund-level tax is limited under the Internal Revenue Code of 1986, as amended.

Real Estate Risk: The value of real estate-linked derivative instruments and other real estate-related securities such as real estate investment trusts (“REITs”) may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment. To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses. REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.

Actual after-tax returns depend on your tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans and individual retirement accounts because such accounts are only subject to taxes upon withdrawal. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from absolute return asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. The research providers’ absolute return asset allocation approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek to achieve consistent absolute positive returns over time regardless of the market environment.

In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in fixed income or equity-oriented investments across global markets, using varying active asset allocation strategies among different security types, asset classes, yield and duration, valuation analyses, and currency exposure considerations.

The Fund may utilize an absolute return asset allocation strategy that builds on a foundation of alternative investments, such as long/short equity funds that seek a modest positive return from equity investments, that attempts to stay insulated from general stock market volatility, combined with opportunistic equity and fixed income investments strategically selected to enhance returns. The Fund may invest in Underlying Funds that use alternative strategies and/or use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk profile of the Underlying Fund, to replace more traditional direct investments, or to obtain exposure to certain markets.

The Fund may also utilize absolute return asset allocation strategies that allocate assets to various fixed income instruments and sectors using various passive index-oriented ETFs focusing on instruments such as U.S. Government bonds and notes, corporate bonds, bank loans, mortgage-related securities and asset-backed securities, inflation-protected debt securities, corporate bonds of various quality levels and maturity/duration, and cash equivalent investments. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure at the appropriate times, while increasing exposure to attractive sectors on a timely basis.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investment in Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Maturity Risk: The Fund may invest in fixed income securities with a range of maturities. Generally, the longer a security’s maturity, the greater the risk that interest rate fluctuations may adversely affect the value of the security.

Municipal Securities Risk: The risk of a municipal security depends on the ability of the issuer, or any entity providing a credit enhancement, to continue to meet its obligations for the payment of interest and principal when due.

Actual after-tax returns depend on your tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans and individual retirement accounts because such accounts are only subject to taxes upon withdrawal. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

Strategy [Heading]

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds (both actively and passively managed) and exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of asset classes. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

The Fund has broad flexibility to allocate its assets among a wide variety of debt and equity securities and real estate investment trusts (“REITs”). As part of its principal investment strategy or for temporary defensive purposes, any portion of the Fund’s assets may also be invested in cash and cash equivalents. The Fund may invest in such instruments directly or indirectly through its investment in Underlying Funds. The Fund’s approach is flexible and allows the Advisor to shift the Fund’s allocations in response to changing market conditions. As a result, the Fund may at times be invested in a single or multiple asset classes, markets or sectors. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar.

The Advisor’s asset allocation decisions are based on different factors and analytical approaches, derived from asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. In attempting to achieve the Fund’s investment objective, the Advisor monitors and adjusts the Fund’s asset allocations as necessary.

Under normal circumstances, the Fund will be expected to allocate between 40% and 80% of its assets to equity securities and investments that provide exposure to equity securities and between 20% to 60% of its assets to fixed income securities and investments that provide exposure to fixed income securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions or short-term market opportunities. Under normal market conditions, the Fund will be expected to allocate approximately 60% of its assets to equity securities and investments that provide exposure to equity securities and 40% of its assets to fixed income securities and investments that provide exposure to fixed income securities, including cash equivalents.

The Fund’s fixed income allocation may include, but is not limited to, investments made directly or indirectly via the Underlying Funds in debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations. The Fund’s fixed income allocation may also include higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. It is possible that a significant portion of the Fund’s fixed income allocation may be invested, directly or indirectly, in non-investment grade fixed income investments with varying maturities.

The Fund may invest, directly or indirectly, in domestic and international equities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)). The Fund’s equity allocation may include investments made directly or indirectly via the Underlying Funds in both small- and large-capitalization companies and both growth and value stocks. The Fund’s equity allocation may also include equity securities from emerging international markets, and both domestic and international real estate securities.

The Fund may invest in Underlying Funds that use alternative strategies (e.g., long/short strategies – equity and fixed income, market-neutral strategies, and absolute return/global macro strategies) and/or use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies.

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds (both actively and passively managed) and exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of fixed income and equity securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from volatility managed and income focused asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. The research providers’ volatility managed and income focused asset allocation approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek to achieve consistent returns over time regardless of the market environment while also seeking to generate high levels of income.

The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations, higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt, dividend-paying securities of small- and large-capitalization companies, growth and value stocks, equity securities from developed and emerging market countries, and both domestic and international real estate securities. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. It is possible that a significant portion of the Fund’s assets may be invested, directly or indirectly, in non-investment grade fixed income investments with varying maturities.

The Fund may utilize an asset allocation strategy that builds on a foundation of alternative investments, such as long/short equity funds that seek a modest positive return from equity investments, that attempts to stay insulated from general stock market volatility, combined with opportunistic equity and fixed income investments strategically selected to enhance returns.

The Fund’s asset allocation mix among fixed income, equity and cash equivalent money market securities is intended to change over time. The Fund does not have a set target asset allocation mix. If the Advisor believes that market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes. The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified.

The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investments in Underlying Funds. For purposes of this section, the term “Fund” should be read to mean the Fund and the Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund seeks exposure to various asset classes, which may vary significantly over time but is generally expected to include exposure to equity markets, bond markets, interest rates, commodities, and currencies. The sub-advisor uses proprietary quantitative models to identify price trends in equity, fixed income, currency and commodity instruments across time periods of various lengths. The sub-advisor believes that asset prices may show persistent trading behavior due to a number of behavioral biases among market participants as well as certain risk-management policies that will identify assets to purchase in upward-trending markets and identify assets to sell in downward-trending markets.

Although the Fund seeks exposure across a variety of asset classes, it may emphasize one or two of the asset classes or a limited number of exposures within an asset class. There are no geographic limits on the asset class exposures and there is great flexibility in looking for investments around the globe, including in emerging markets. The Fund may have both “short” and “long”’ exposures within an asset class based upon potential opportunities. A “short” exposure will benefit when the underlying asset class decreases in price. A “long” exposure will benefit when the underlying asset class increases in price.

The Fund expects to pursue its investment strategies by making extensive use of a variety of derivative instruments, including futures contracts, forward currency contracts and swaps. A futures contract is a standard binding agreement to buy or sell a specified quantity of an underlying reference asset, such as a specific security, currency or commodity, at a specified price at a specified later date. A forward currency contract involves an obligation to purchase or sell a specific non-U.S. currency in exchange for another currency, which may be U.S. dollars, at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Generally, swap agreements are contracts between the Fund and another party (the swap counterparty) involving the exchange of payments on specified terms over periods ranging from a few days to multiple years.

The Fund may also invest in exchange-traded funds (“ETFs”) or exchange-traded notes (“ETNs”) through which the Fund can participate in the performance of one or more asset classes.

In connection with the Fund’s managed futures strategy, the Fund’s portfolio may be concentrated in the financial services industry, which means the Fund may invest more than 25% of its total assets in securities and other obligations (for example, bank certificates of deposit, repurchase agreements and time deposits) of issuers in such industry. A significant portion of the assets of the Fund may be invested directly or indirectly in money market instruments, which may include, but are not limited to, U.S. Government securities, U.S. government agency securities, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market mutual fund shares, and cash and cash equivalents with one year or less term to maturity. These cash or cash equivalent holdings serve as collateral for certain of the Fund’s derivatives positions.

As a result of the Fund’s use of derivatives, the Fund may have highly leveraged exposure to one or more asset classes at times. The Investment Company Act of 1940, as amended (the “1940 Act”) and the rules and interpretations thereunder impose certain limitations on the Fund’s ability to use leverage; however, the Fund is not subject to any additional limitations on its net long and short exposures. For example, the Fund, on average, could hold instruments that provide three to four times the net return (positive or negative) of an unleveraged investment in the equities, bonds, interest rates, commodities, or currencies underlying such instruments. When taking into account derivative instruments and instruments with a maturity of one year or less at the time of acquisition, the Fund’s strategy will result in frequent portfolio trading and high portfolio turnover (typically greater than 300% per year). The Advisor expects the Fund’s net asset value over short term periods to be volatile because of the significant use of instruments that have a leveraging effect. Volatility is a statistical measurement of the dispersion of returns of a security or fund or index, as measured by the annualized standard deviation of its returns. Higher volatility generally indicates higher risk.

Although the Fund does not intend to invest in physical commodities directly, the Fund expects to obtain investment exposure to commodities and commodity related derivatives by investing in a wholly-owned subsidiary organized under the laws of the Cayman Islands that will make commodity-related investments (the “Subsidiary”). Through the Subsidiary, the Fund may invest in “commodity-linked” or “commodity index-linked” investments such as commodity futures contracts and commodity swap agreements.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Focus Risk: To the extent the Fund concentrates its investments in securities and other obligations of issuers in the financial services industry, the Fund is particularly vulnerable to events affecting companies in such industry. Examples of risks affecting the financial services industry include changes in governmental regulation, issues relating to the availability and cost of capital, changes in interest rates and/or monetary policy and price competition. In addition, financial services companies are often more highly leveraged than other companies, making them inherently riskier.

Credit Risk: Individual issues of fixed income securities may be subject to the credit risk of the issuer. The issuer of a fixed income security may experience financial problems, causing it to be unable to meet its payment obligations.

Leverage Risk: The Fund’s use of derivatives such as futures contracts, forward contracts and swaps has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying a derivatives instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in derivatives at all.

Emerging Markets Risk: In addition to the risks generally associated with investing in foreign securities described below, countries with emerging markets may also have relatively unstable governments, fewer shareholder protections, and more limited economies and securities markets.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Management Risk: An investment or allocation strategy used by the Advisor or the sub-advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Short Position Risk: The Fund may engage in short position derivative activities. Short position derivatives are speculative and more risky than "long" positions (purchases) because the cost of the replacement security or derivative is unknown. You should be aware that any strategy that includes selling securities short could suffer significant losses. Shorting will also result in higher transaction costs (such as interest and dividends), which reduce the Fund’s return, and may result in higher taxes.

Valuation Risk: The Fund is subject to the risk that it has valued certain securities at a higher price than the price at which they can be sold. The risk may be especially pronounced for investments, such as derivatives, that may be classified as illiquid or may become classified as illiquid.

Wholly-Owned Subsidiary Risk: The Subsidiary will not be subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could affect the ability of the Fund and/or Subsidiary to operate as described herein and could negatively affect the Fund and its shareholders. By investing in the Fund, you indirectly bear the expenses of the Subsidiary. Gains or losses from trading in commodity-linked derivatives, such as those held by the Subsidiary, may be taxed, in part, as long term capital gains or losses and, in part, as short term capital gains or losses. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income and taxed to Fund shareholders as such.

Tax Risk – Investment in Commodities: The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives or the Subsidiary was treated as non-qualifying income for purposes of the Fund’s qualification as a regulated investment company, the Fund might fail to qualify as such and be subject to federal income tax at the Fund level.

Managed Futures Regulatory Risk: Government regulation of the use of futures and other derivatives by mutual funds is continuing to evolve. In 2015, the Securities and Exchange Commission proposed a new rule designed to modernize the regulation of derivatives usage by mutual funds that could have a significant impact on the manner in which certain managed futures mutual funds, including the Fund, operate. If this new rule is adopted as proposed, it may compel the Fund to change its investment strategy, make the Fund’s investment strategy more costly to implement, or require the Fund to cease operating as an investment company registered under the 1940 Act. The likelihood of these events, or the impact of potential future regulation, is currently not predictable.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the period from the Fund’s inception on April 30, 2018 to the fiscal year ended March 31, 2019, the portfolio turnover rate for the Fund was 388.79% of the average value of its portfolio.

The following Example is intended to help you compare the cost of investing in Shares of the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example reflects adjustments made to the Fund’s operating expenses due to the fee waiver and/or expense assumption by the Advisor for the 1-year number only.

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds and exchange-traded funds (“ETFs”), in addition to direct investments. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

Under normal circumstances, the Fund will make investments in fixed income securities, including cash equivalents, that primarily have a maturity that is between 0 and 5 years. The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. In pursuit of the Fund’s secondary investment objective of capital preservation, the Fund expects under normal circumstances to invest a significant portion of its assets in cash and cash equivalents, including by investing approximately 25% to 50% of the Fund’s total assets in money market funds.

In selecting debt securities for the Fund, the Advisor develops an outlook for credit markets, interest rates, currency exchange rates and the economy, analyzes individual credit and prepayment risks, and uses other security selection techniques. The proportion of the Fund’s assets committed to investment in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based on the Advisor’s outlook for the U.S. economy and the economies of other countries in the world, the financial markets and other factors.

The Fund may shift its investments from one asset class to another based on the Advisor’s analysis of the best opportunities for the Fund’s portfolio in a given market. The Fund may invest up to 20% of its total assets in bonds rated below investment grade. The Fund may invest up to 20% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.

The Fund’s asset allocation mix may change periodically over time. The Fund does not have a set target asset allocation mix. If the Advisor believes that market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified. In certain circumstances the Fund may be fully invested in cash equivalents securities for an extended period of time.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investments in Underlying Funds. For purposes of this section, the term “Fund” should be read to mean the Fund and the Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives. There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, the Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Exchange-Traded Notes Risk: ETNs are debt securities that are traded on an exchange (e.g., the New York Stock Exchange) whose returns are linked to the performance of a particular market benchmark or strategy. An ETN generally reflects the risks associated with the assets composing the underlying market benchmark or strategy it is designed to track. ETNs also are subject to issuer and fixed-income risks.

Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio of debt securities. Interest rates in the United States are at, or near, historic lows, which may increase the Fund’s exposure to risks associated with rising interest rates. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund’s manager might wish to sell. Lower rated securities (“junk bonds”) are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline.

High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by a nationally recognized statistical rating organizations (“NRSRO”). Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.

U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. For example, Connecticut Avenue Securities issued by the Federal National Mortgage Association and Structured Agency Credit Risk debt notes issued by the Federal Home Loan Mortgage Association carry no guarantee whatsoever and the risk of default associated with these securities would be borne by the Fund. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Non-U.S. Government Obligations Risk: For non-U.S. government obligations, there is the risk that payments on a security will not be made when due, or the value of such security will decline, because the security is not issued or guaranteed as to principal or interest by the U.S. government or by agencies or authorities controlled or supervised by and acting as instrumentalities of the U.S. government or supported by the right of the issuer to borrow from the U.S. government.

Foreign Securities Risk: The risks of investing in foreign securities can increase the potential for losses in the Fund and may include currency fluctuations, political and economic instability, less government regulation, less publicly available information, limited trading markets, differences in financial reporting standards, fewer protections for passive investors and less stringent regulation of securities markets.

Collateralized Debt Obligations Risk: Collateralized debt obligations (“CDOs”) are subject to the following risks: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or quality or go into default or be downgraded; (iii) a Fund may invest in tranches of a CDO that are subordinate to other classes; and (iv) the risk of disputes with the issuer, difficulty in valuing the security or unexpected investment results.

Preferred Stock Risk: A preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. Preferred stocks often behave like debt securities, but have a lower payment priority than the issuer’s bonds or other debt securities. Therefore, they may be subject to greater credit risk than those of debt securities. Preferred stocks also may be significantly less liquid than many other securities, such as corporate debt or common stock.

Convertible Securities Risk: The value of convertible securities may fall when interest rates rise and increase when interest rates fall. The prices of convertible securities with longer maturities tend to be more volatile than those with shorter maturities. Value also tends to change whenever the market value of the underlying common or preferred stock fluctuates. The Fund could lose money if the issuer of a convertible security is unable to meet its financial obligations.

Mortgage- and Asset-Backed Securities Risk: Payments on mortgage- and asset-backed securities depend upon assets held by the issuer and collections on the underlying mortgages or loans. Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Mortgage- and asset-backed securities are also subject to prepayment risk, which is the risk that the borrower will prepay some or all of the principal owed to the issuer. If that happens, a Fund may have to replace the security by investing the proceeds in a less attractive security. In certain market conditions, asset-backed securities may experience volatile fluctuations in value and periods of illiquidity.

Inflation-Linked Securities Risk: Unlike traditional fixed income securities, the principal and interest payments of inflation-linked securities are adjusted periodically based on the inflation rate. The value of the Fund’s inflation-linked securities may be vulnerable to changes in expectations of inflation or interest rates and there is no guarantee that the Fund’s use of these instruments will be successful.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

New Fund Risk: The Fund is new with limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size.

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds, exchange-traded funds (“ETFs”) and closed-end funds, in addition to direct investments in securities and certain derivatives. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from volatility-managed and income-focused asset allocation approaches. These approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek high total return and income, managed to contain the potential magnitude of drawdowns in high volatility markets. The Fund may invest up to 20% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.

In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in various types of domestic and international fixed income securities, domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and cash equivalent money market securities. The Fund invests in fixed income securities that primarily have a maturity that is between 1 and 10 years and are rated BBB- or higher, or are unrated and deemed to be of comparable quality by the Advisor; provided, however, that the Fund may invest up to 50% of its total assets in bonds rated below investment grade. Under normal circumstances, the Fund’s portfolio will have an average duration of 2 to 5 years. In some instances, the Fund’s average duration may exceed this range but is not expected to exceed that of the Bloomberg Barclays US Aggregate Bond Index. Duration is a measurement of price sensitivity to interest rate changes.

The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations, higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt, preferred stock, dividend-paying securities of small- and large-capitalization companies, business development companies (“BDCs”), publicly traded real estate investment trusts (“REITs”), non-traded unregistered REITs, ETFs, and pooled investment funds including private investment funds that are not registered under the 1940 Act (“private funds”) that provide exposure to pools of whole loans, including those sourced through peer-to-peer or marketplace lending platforms. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. Under normal circumstances, the Fund will make investments in fixed income securities that primarily have a maturity that is between 1 and 10 years.

The Fund may allocate assets to ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The ETFs in which the Fund may invest include those that invest primarily in senior bank loans (also referred to as leveraged loans). The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.

The Fund may engage in a strategy of purchasing and selling (writing) call and put options on indexes or ETFs (hereafter referred to as “call options” and “put options”). The writer of a call option receives cash (the “premium”) from the purchaser. In return, the purchaser of a call option has the right to any appreciation in the value of the underlying index or ETF over a fixed price (the “exercise price”) on a certain date in the future (the “expiration date”). If the purchaser does not exercise the option, the writer of the option retains the premium. If the purchaser exercises the option, the writer of the option pays the purchaser the difference between the value of the underlying index or ETF and the exercise price of the option.

The value of a call option generally increases as the prices of the stocks constituting the underlying index or ETF increase, and decreases as those stocks decrease in price. Conversely, the value of a put option generally increases as the prices of the stocks constituting the underlying index or ETF decrease, and decreases as those stocks increase in price. The premium, the exercise price and the value of the underlying index or ETF will determine the gain or loss realized by the Fund on a written or purchased option. When the Fund has written an option, it generally can repurchase the option prior to the expiration date, ending its obligation. In such case, the difference between the cost of repurchasing the option and the premium received will determine the gain or loss realized by the Fund. While writing call options may reduce the Fund’s volatility and provide a source of steady cash flow, it may also reduce the Fund’s ability to profit from increases in the value of the underlying index or ETF.

Using the proceeds from its written call options, the Fund may buy put options in an attempt to hedge against a significant market decline in the underlying index or ETF that may occur over a short period of time. In addition, the Fund may write call options or put options on the underlying indexes of the ETFs in which the Fund is invested.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investments in Underlying Funds. For purposes of this section, the term “Fund” should be read to mean the Fund and the Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Closed-End Fund Risk: Closed-end funds involve investment risks different from those associated with other investment companies. The shares of closed-end funds frequently trade at a premium or discount relative to their net asset value, and many closed-end funds use leverage, or borrowed money, to try to increase returns. In addition, distributions by a closed-end fund may include a return of capital, which would reduce the fund’s net asset value and its earnings capacity. Finally, closed-end funds are allowed to invest in a greater amount of illiquid investments than open-end mutual funds.

Business Development Company Risk: BDCs are closed-end investment companies that have elected to register as BDCs. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the BDC when the fund invests in shares of the BDC. BDCs primarily invest in privately-held and small- to medium- capitalization public companies, and are generally considered to be non-rated or below investment grade. The fair values of these investments often are not readily determinable. This could cause the Fund’s investments in a BDC to be inaccurately valued, including overvalued. BDC revenues, income (or losses) and valuations can, and often do, fluctuate suddenly and dramatically, and they face considerable risk of loss. In addition, BDCs often borrow funds to make investments and, as a result, are exposed to the risks of leverage. Leverage magnifies the potential loss on amounts invested and therefore increases the risks associated with an investment in a BDC’s securities.

Private Funds Risk: The Fund’s investment in private funds will require it to bear a pro rata share of the vehicles’ expenses, including management and performance fees. The fees the Fund pays to invest in a private fund may be higher than if the manager of the private fund managed the Fund’s assets directly. Furthermore, private funds, like the other Underlying Funds in which the Fund may invest, are subject to specific risks, depending on the nature of the vehicle, and also may employ leverage such that their returns are more than one times that of their benchmark which could amplify losses suffered by the Fund when compared to unleveraged investments. Shareholders of the private funds are not entitled to the protections of the 1940 Act. The majority of private funds permit redemptions only quarterly (although others are more frequent) and these withdrawal limitations restrict the Advisor’s ability to terminate investments in private funds. Additionally, because private funds are not publicly traded, the Fund’s investments in them may be more difficult to value than the Fund’s investments in publicly traded securities.

Debt/Fixed Income Securities Risk. An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio of debt securities. Interest rates in the United States are at, or near, historic lows, which may increase the Fund’s exposure to risks associated with rising interest rates. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund’s manager might wish to sell. Lower rated securities (“junk bonds”) are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline.

Equity Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The stock market may experience declines or stocks in the Fund’s portfolio may not increase their earnings at the rate anticipated. The Fund’s NAV and investment return will fluctuate based upon changes in the value of its portfolio securities.

Options Risk: The value of the Fund’s options positions will fluctuate in response to changes in the value of the underlying securities. Writing call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. In addition, the Fund continues to bear the risk of declines in the underlying securities on which the option is written. When purchasing put options, the Fund risks losing all or part of the cash paid for purchasing the option. As the writer of a put option, the Fund has a risk of loss should the underlying securities decline in value. If the value of the underlying securities declines below the exercise price of the put option and the put option is exercised, the Fund, as the writer of the put option, will be required to buy the underlying securities at the exercise price, and the Fund will incur a loss to the extent that the current market value of the underlying securities is less than the exercise price of the put option. However, the loss will be offset in part by the premium received from the buyer of the put option. Unusual market conditions or the lack of a ready market for any particular option at a specific time may reduce the effectiveness of the Fund’s option strategies, and for these and other reasons the Fund’s option strategies may not reduce the Fund’s volatility to the extent desired.

Leverage Risk: The Fund’s investments in closed-end funds, leveraged ETFs and ETNs, and derivatives such as futures contracts, forward contracts and swaps have the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying a derivatives instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in derivatives at all.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Senior Loan Risk: Investments in senior loans are subject to loan risk generally. Senior loans typically are below investment grade and are considered speculative because of the credit risk of their issuers. Their issuers are more likely to default on their payments of interest and principal owed, and such defaults could reduce the Fund’s NAV and income distributions. In addition, the Fund may have to sell securities at lower prices than it otherwise would to meet cash needs or it may have to maintain a greater portion of its assets in cash equivalents than it otherwise would because of impairments and limited liquidity of the collateral supporting a senior loan, which could negatively affect the Fund’s performance.

Marketplace Loan Risk: Investments in loans sourced through marketplace lending platforms are subject to additional risks than those applicable to investments in loans generally. An Underlying Fund may not have direct recourse against the borrower or may be otherwise limited in its ability to directly enforce its rights under the loan. Default history for alternative lending platforms is limited. Future defaults may be higher than historical defaults and the timing of defaults may vary significantly from historical observations. An Underlying Fund may have limited knowledge about the underlying loans to which it has exposure and is dependent upon the platform for information regarding the loans and borrowers’ credit information. Such information may be incomplete, inaccurate or outdated and may, therefore, not accurately reflect the borrowers’ actual creditworthiness. In addition, investments in loans sourced through a marketplace lending platform may also be negatively impacted if the platform or a third-party service provider becomes unable or unwilling to fulfill its obligations in servicing the loans.

Real Estate Risk: The value of real estate-linked derivative instruments and other real estate-related securities such as REITs may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment. To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses. REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.

New Fund Risk: The Fund is new with limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the period from the Fund’s inception on April 30, 2018 to the fiscal year ended March 31, 2019, the portfolio turnover rate for the Fund was 123.50% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds, exchange-traded funds (“ETFs”), closed-end funds and business development companies (“BDCs”), in addition to direct investments. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

The Advisor may invest in securities of companies of various market capitalizations. The Fund considers “large capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 1000^® Index. The Fund considers “small-to-medium capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 2500^™ Index.

The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. The Fund may invest in debt securities of any maturity or quality. The Fund may invest in equity securities which include domestic and foreign common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), business development companies (“BDCs”), Master Limited Partnerships (“MLPs”), publicly traded real estate investment trusts (“REITs”), non-traded unregistered REITs, ETFs and pooled investment funds including private investment funds that are not registered under the 1940 Act (“private funds”) that provide exposure to pools of whole loans, including those sourced through peer-to-peer or marketplace lending platforms.

MLPs are businesses organized as limited partnerships that trade their proportionate shares of the partnership (units) on a public exchange. MLPs are required to pay out most or all of their earnings in distributions. The Fund may invest up to 30% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.

The Fund may allocate assets to ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of the money you have invested in the Fund. The Fund is subject to a number of risks either directly or indirectly through its investments in Underlying Funds. For purposes of this section, the term “Fund” should be read to mean the Fund and the Underlying Funds. The following risks could affect the value of your investment in the Fund:

Management Risk: An investment or allocation strategy used by the Advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Loan Risk: The value of an investment in a loan is entirely dependent on the borrower’s continued and timely payments. If a borrower fails to make interest payments or repay principal when due on a loan in which the Fund has direct or indirect investment exposure, or if the value of a loan decreases, the value of the Fund’s investment will be adversely affected. Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take significantly longer than 7 days for investments in loans to settle, which can adversely affect an Underlying Fund’s ability to timely honor redemptions.

Master Limited Partnership Risk. Investing in Master Limited Partnerships (“MLPs”) entails risk related to fluctuations in energy prices, decreases in supply of or demand for energy commodities, unique tax consequences due to the partnership structure and various other risks.

New Fund Risk: The Fund is new with limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size.

The following Example is intended to help you compare the cost of investing in Institutional Shares of the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Institutional Shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example reflects adjustments made to the Fund’s operating expenses due to the fee waiver and/or expense assumption by the Advisor for the 1-year number only.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its assets in fixed income securities and/or investments that provide exposure to fixed income securities. Investments in fixed income securities may include, but are not limited to, debt securities of governments and government agencies throughout the world (including the United States), their agencies and instrumentalities and supranational organizations, municipal and local/provincial debt, debt securities of corporations, commercial paper, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities, inverse floater securities, interest-only and principal-only securities, equipment trusts, other securitized or collateralized debt obligations, and cash equivalents.

The Fund seeks to achieve its investment objective by investing primarily in fixed and floating rate debt securities, debt obligations of governments, government-related or corporate issuers worldwide and/or investments that provide exposure to fixed income securities. The Fund also regularly enters into currency-related transactions in both developed and emerging markets, in an attempt to generate total return and manage risk from differences in global short-term interest rates. The Fund may invest in securities or structured products that are linked to or derive their value from another security, index or asset (derivative investments). The Fund may enter into various currency-related transactions involving derivative instruments, including currency and cross-currency forwards, currency and cross-currency swaps, currency and currency index futures contracts, and currency options. In addition, the Fund’s assets will be, under normal circumstances, invested in issuers located in or denominated in at least three countries (including the United States) and the Fund may invest a substantial portion (up to 75%) of its assets in emerging markets.

The Fund’s investments in fixed income securities may have all types of interest rate payment and reset terms, including fixed rate, adjustable rate, zero coupon, pay-in-kind and auction rate features. In addition, the fixed income securities and related instruments purchased by the Fund may be denominated in any currency, have coupons payable in any currency and may be of any maturity or duration. The average maturity of fixed income securities and related instruments in the Fund’s portfolio will fluctuate depending on the sub-advisors’ outlook on changing market, economic, and political conditions. Additionally, the average duration of the Fund will be a combination not only of the duration of the debt securities in the Fund but also the presence of fixed income derivatives, as discussed below. The Fund may utilize fixed income derivatives to lower or extend the Fund’s duration substantially. The Fund may invest in fixed income securities of any credit quality, including below investment grade or high yield securities (sometimes referred to as “junk bonds”), and may buy bonds that are in default. It is anticipated that the Fund will frequently hold a substantial position in high yield securities.

The Fund’s currency exposure will be actively managed and the sub-advisors will attempt to generate total returns and manage risk by identifying relative valuation discrepancies among global currencies as well as implementing hedging strategies to limit unwanted currency risks. These decisions are integrated within the macroeconomic framework analysis of global market and economic conditions.

The following Example is intended to help you compare the cost of investing in Institutional Shares of the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Institutional Shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year, and that the Fund’s operating expenses remain the same. The Example reflects adjustments made to the Fund’s operating expenses due to the fee waiver and/or expense assumption by the Advisor for the 1-year number only.

Strategy [Heading]

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange–traded notes (“ETNs”).

In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, into a diversified portfolio consisting of domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)), domestic and international fixed income securities and cash equivalent money market securities.

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund operates as a fund of funds, investing primarily in registered mutual funds (both actively and passively managed) and exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of fixed income and equity securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Liquidity Risk: Liquidity risk is the risk that certain investments may be difficult or impossible to buy or sell at the time and price that a Fund would like to buy or sell the security.

Management Risk: An investment or allocation strategy used by the Advisor or the sub-advisor may fail to produce the intended results.

Market Risk: The value of the Fund’s investments and the net asset values of the shares of the Fund will fluctuate in response to various market and economic factors related to the equity, fixed income and currency markets as well as the financial condition and prospects of companies in which the Fund invests.

Short Position Risk: The Fund may engage in short position derivative activities. Short position derivatives are speculative and more risky than “long” positions (purchases) because the cost of the replacement security or derivative is unknown. You should be aware that any strategy that includes selling securities short could suffer significant losses. Shorting will also result in higher transaction costs (such as interest and dividends), which reduce the Fund’s return, and may result in higher taxes.
