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 22.67% of the average value of its portfolio.

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 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”).

Under normal circumstances, the Fund will invest at least 70% all of its assets in fixed income securities or investments that provide exposure to fixed income securities, including Underlying Funds that in turn invest in fixed income securities or investments that provide exposure to fixed income securities. The Fund may invest a portion of its remaining assets in cash equivalents and other money market securities.

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

The Fund’s assets are typically allocated, either directly or indirectly via the Underlying Funds, among various types of domestic and foreign fixed income securities (including domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)). These may 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 securities. The Fund may invest, directly or indirectly, in higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. 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 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 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 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:

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 Fund 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.

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.

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.

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. 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.

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.

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.

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. In addition, the use of currency derivatives may not match or fully offset changes in the value of the underlying non-dollar-denominated or bank assets.

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.

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.

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.

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.

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.

Loan Risk: Loans are subject to risk of loss, sensitivity to interest rate and economic changes, valuation difficulties and potential illiquidity 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.
