Portfolio Turnover [Text Block]

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 214.84% of the average value of its portfolio.

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.

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.

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 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 profile of the Underlying Fund, to replace more traditional direct investments, or to obtain exposure to certain markets.

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.

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]

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:

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.

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. ETFs have management fees and other expenses which the Fund will indirectly bear.

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.

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.

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.

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.

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.

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.

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 and have a greater risk of default. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.

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.

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 may be illiquid, volatile, difficult to value, and the Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price.

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.

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. 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.

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 entity-level tax is limited under the Internal Revenue Code.

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.

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”) has attempted to support the U.S. economic recovery by keeping the federal funds rate at a low level and purchasing large quantities of securities issued or guaranteed by the U.S. government, its agencies or instrumentalities on the open market (“Quantitative Easing”). As the Federal Reserve reduces Quantitative Easing, and when the Federal Reserve raises the federal funds rate, interest rates across the U.S. financial system may rise. These policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Underlying Fund investments, which could cause the value of a Fund’s investments and share price to decline. If an Underlying Fund invests in derivatives tied to fixed-income markets, the Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives. To the extent the Underlying Fund experiences high redemptions because of these policy changes, the Underlying Fund may experience increased portfolio turnover, which will increase the costs the Underlying 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.

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.
