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. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended May 31, 2020, the Fund’s portfolio turnover rate was 9.52 % of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s portfolio managers seek to achieve the Fund’s investment objective of total return by investing in other investment companies, including mutual funds and exchange-traded funds that are registered under the Investment Company Act of 1940, as amended (the "1940 Act”) and not affiliated with the Fund (“Portfolio Funds”) or making direct investments in fixed income securities based upon institutional research. These investments may include mortgage backed securities, asset backed securities, commercial mortgage backed securities, non-agency mortgage backed securities, corporate investment grade securities, convertible securities, high yield -high risk bonds (commonly known as “junk bonds”), securities issued or guaranteed by certain U.S. Government agencies, instrumentalities and sponsored enterprises, preferred securities, and global debt securities. The Fund’s allocation of its assets into various asset classes will depend on the views of the Advisor or Sub-Advisor as to the best value relative to what is currently presented in the marketplace.

The Fund may invest in fixed income securities of any maturity and any credit rating, including below investment grade securities (commonly referred to as “junk”), bonds of issuers in default, and unrated bonds. The fixed income securities in which the Fund invests do not have an established average portfolio duration and the average portfolio durations will vary. Duration is a measure of the sensitivity of the price of a bond or other debt instrument to a change in interest rates. In general, the higher the duration, the more a bond’s price will drop as interest rates rise (and the greater the interest rate risk). The Fund will not be limited in its investments by sector criteria, and may invest in foreign securities, including foreign securities in emerging markets.

The Advisor and Sub-Advisor each manage a portion of the Fund as determined by the Advisor based on prevailing fixed income market conditions. The Adviser’s investment model indicates which fixed income sectors are more or less favorable at a given time. To the extent that the Advisor’s model indicates that the Fund should be invested in non-agency mortgage backed securities, that portion of the Fund’s portfolio is allocated to the Sub-Advisor. The Advisor is responsible for managing the remaining portion of the Fund that is not invested in non-agency mortgage backed securities.

In managing its portion of the Fund, the Advisor uses and investment model for analyzing market trends. The investment model includes factors such as price momentum, volatility, comparative indicators relative to certain indices and a recession model (a model that measures the probability of a recession within the next several months based on leading economic indicators). The Advisor utilizes research and valuation metrics to determine which fixed income asset classes have the greatest potential for producing positive performance and income, with a focus on capturing upside performance while protecting against loss. Valuation metrics are measures of a company’s performance, financial health and prospects for future earnings by comparing the market’s opinion (share price) to actual reported earnings to help predict a company’s prospects. When the Advisor’s model indicates a negative market trend, the Fund may utilize defensive investments, including ETFs that invest in treasury bonds, exchange traded notes (“ETNs”) and leverage and inverse ETFs to hedge the Fund’s portfolio . The Fund may hold significant cash or inverse ETF positions during unfavorable market conditions.

In managing its portion of the Fund, the Sub-Advisor analyzes a variety of factors when determining the credit quality of the non-agency mortgage backed securities in which the Fund invests and in selecting securities for the Fund’s portfolio, such as collateral quality, credit support, and structure. The Sub-Advisor also considers market conditions in selecting securities for the Fund. The Sub-Advisor attempts to diversify risks that arise from position sizes, geography, ratings, duration, deal structure and collateral values. The Sub-Advisor seeks to limit risk of principal by targeting assets that it considers undervalued. The Sub-Advisor may sell a security if the Sub-Advisor no longer believes it is undervalued or if the Sub-Advisor believes that a different security will better help the Fund achieve its investment objective.

The portfolio managers will sell a portfolio security when a more attractive investment opportunity is identified, or the Fund’s portfolio needs to be rebalanced due to increases or decreases in the Fund’s net assets. A s a result of this strategy, the Fund may have a relatively high level of portfolio turnover compared to other mutual funds, which may affect the Fund’s performance due to higher transaction costs and higher taxes. The Fund may invest up to 15% of its net assets in illiquid investments.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS OF INVESTING IN THE FUND

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The loss of your money is a principal risk of investing in the Fund. Investments in the Fund are subject to investment risks, including the possible loss of some or the entire principal amount invested. There can be no assurance that the Fund will be successful in meeting its investment objective. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation or any other government agency. The Fund will be subject to the following principal risks:

Mortgage-Backed Securities Risk. Mortgage-backed securities risk refers to the risk that borrowers may default on their mortgage obligations or the guarantees underlying the mortgage-backed securities will default or otherwise fail and that, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security’s duration, and reduce the value of the security. The liquidity of mortgage-backed securities can change significantly over time.

Asset-Backed Securities Investment Risk. Asset-backed securities risk is the risk that borrowers may default on the obligations that underlie the asset-backed security and that, during periods of falling interest rates, asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate, and the risk that the impairment of the value of the collateral underlying a security in which the Fund invests (due, for example, to non-payment of loans) will result in a reduction in the value of the security.

Rating Agencies Risks. Ratings are not an absolute standard of quality, but rather general indicators that reflect only the view of the originating rating agencies from which an explanation of the significance of such ratings may be obtained. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely. Such changes may negatively affect the liquidity or market price of the securities in which the Fund invests. The ratings of securitized assets may not adequately reflect the credit risk of those assets due to their structure.

Liquidity Risk. Liquidity risk exists when particular investments of the Fund would be difficult to purchase or sell, possibly preventing the Fund from selling such illiquid securities at an advantageous time or price, or possibly requiring the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations.

Fund Investing Risk. Investments in other investment companies subject the Fund to additional operating and management fees and expenses. Investors in the Fund will indirectly bear fees and expenses charged by the funds in which the Fund invests, in addition to the Fund’s direct fees and expenses. The Fund’s performance depends in part upon the performance of the investment advisor to each Portfolio Fund, the strategies and instruments used by the Portfolio Funds, and the Advisor’s ability to select Portfolio Funds and effectively allocate fund assets among them.

Control of Portfolio Funds Risk. The Portfolio Funds each have their own unique investment objective, strategies, and risks. There is no guarantee that the Portfolio Funds will achieve their investment objectives and the Fund has exposure to the investment risks of the Portfolio Funds in direct proportion to the allocation of assets among the funds. The investment policies of the Portfolio Funds may differ from the Fund’s policies.

Although the Fund and the Advisor will evaluate regularly each Portfolio Fund to determine whether its investment program is consistent with the Fund’s investment objective, the Advisor will not have any control over the investments made by a Portfolio Fund. The investment advisor to each Portfolio Fund may change aspects of its investment strategies at any time. The Advisor will not have the ability to control or otherwise influence the composition of the investment portfolio of a Portfolio Fund.

ETF Investing Risk. The Fund’s investment in ETFs may subject the Fund to additional risks than if the Fund would have invested directly in the ETF’s underlying securities. These risks include the possibility that an ETF may experience a lack of liquidity that can result in greater volatility than its underlying securities, an ETF may trade at a premium or discount to its net asset value, or an ETF may not replicate exactly the performance of the benchmark index it seeks to track. In addition, the Fund will pay brokerage commissions in connection with the purchase and sale of ETFs in the Fund’s portfolio.

ETN Risk . Similar to ETFs, owning an ETN generally reflects the risks of owning the assets that comprise the underlying market benchmark or strategy that the ETN is designed to reflect. ETNs also are subject to issuer and fixed-income risk.

Credit Risk. Credit risk refers to the risk that an issuer or counterparty will fail to pay its obligations to the Fund when they are due. As a result, the Fund’s income might be reduced, the value of the Fund’s investment might fall, and/or the Fund could lose the entire amount of its investment. Changes in the financial condition of an issuer or counterparty, changes in specific economic, social, or political conditions that affect a particular type of security or other instrument or an issuer, and changes in economic, social or political conditions generally can increase the risk of default by an issuer or counterparty, which can affect a security’s or other instrument’s credit quality or value and an issuer’s or counterparty’s ability to pay interest and principal when due. The values of lower-quality debt securities (commonly known as “junk bonds”) tend to be particularly sensitive to these changes.

Fixed Income Risk. Investments by the Fund and Portfolio Funds in fixed income securities will subject the Fund to the risks associated with such investments. The prices of these securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers. Fixed income securities tend to decrease in value if interest rates rise and vice versa, and the volatility of lower-rated securities is even greater than that of higher-rated securities. Also, longer-term securities are more volatile, so the average maturity or duration of these securities affects risk. Credit risk is the possibility that an issuer will fail to make timely payments of interest or principal or go bankrupt. The lower the rating of a debt security, the greater its risks. Debt instruments rated below investment grade or debt instruments that are unrated and determined by the Advisor to be of comparable quality are predominantly speculative. These instruments, commonly known as “junk bonds,” have a higher degree of default risk and may be less liquid than higher-rated bonds. These instruments may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of high yield investments generally, and less secondary market liquidity.

High-Yield Risk. The Fund and Portfolio Funds may invest in junk bonds, including bonds of issuers in default, and other fixed income securities that are rated below investment grade. Securities in this rating category are speculative and are usually issued by companies without long track records of sales and earnings, or by those companies with questionable credit strength. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of higher grade securities. The retail secondary market for junk bonds may be less liquid than that of higher-rated securities and adverse conditions could make it difficult at times to sell certain securities or could result in lower prices. Additionally, these instruments are unsecured and may be subordinated to other creditor’s claims.

Leveraged and Inverse ETF Risk. Investing in leveraged ETFs will amplify the Fund’s gains and losses. Most leveraged ETFs “reset” daily. Due to the effect of compounding, their performance over longer periods of time can differ significantly from the performance of their underlying index or benchmark during the same period of time. Investments in inverse ETFs will prevent the Fund from participating in market-wide or sector-wide gains and may not prove to be an effective hedge. During periods of increased volatility, inverse ETFs may not perform in the manner they are designed.

Managed Volatility Risk . Techniques used by Advisor to manage the volatility of the Fund’s investments carry the risks that such techniques may not protect against market declines. The techniques may also limit the Fund’s participation in market gains, particularly during periods where market values are increasing but market volatility is high. Further, such techniques may increase portfolio transaction costs, which could result in losses or reduced gains. They also may not be successful as the techniques are subject to the Advisor’s ability to correctly analyze and implement the volatility management techniques in a timely manner.

Inflation Risk. Fixed income securities held by the Fund and Portfolio Funds are subject to inflation risk. Because inflation reduces the purchasing power of income produced by existing fixed income securities, the prices at which fixed income securities trade will be reduced to compensate for the fact that the income they produce is worth less. This potential decrease in market value of fixed income securities would result in a loss in the value of the Fund’s portfolio.

Interest Rate Risk. Interest rates may rise resulting in a decrease in the value of the fixed income securities held by the Fund and Portfolio Funds or may fall resulting in an increase in the value of such securities. Interest rates are currently at historic lows due to the various federal government stimulus programs as a result of the COVID-19 pandemic. Fixed income securities with longer maturities involve greater risk than those with shorter maturities.

Cash and Cash Equivalents Risk . At any time, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time.

Convertible Securities Risk. Convertible securities are fixed income securities that the Fund or a Portfolio Fund has the option to exchange for equity securities at a specified conversion price. The option allows the Fund or a Portfolio Fund to realize additional returns if the market price of the equity securities exceeds the conversion price. Convertible securities have lower yields than comparable fixed income securities and may provide lower returns than non-convertible fixed income securities or equity securities depending upon changes in the price of the underlying equity securities.

Corporate Debt Securities Risk. The Fund and Portfolio Funds may invest in corporate debt securities. Corporate debt securities are fixed income securities issued by businesses. Notes, bonds, debentures, and commercial paper are the most prevalent types of corporate debt securities. The credit risks of corporate debt securities vary widely among issuers. In addition, the credit risk of an issuer’s debt security may vary based on its priority for repayment, meaning that issuers might not make payments on subordinated securities while continuing to make payments on senior securities or, in the event of bankruptcy, holders of senior securities may receive amounts otherwise payable to the holders of subordinated securities.

Foreign Securities and Emerging Markets Risk. F oreign securities have investment risks different from those associated with domestic securities. The value of foreign investments may be affected by the value of the local currency relative to the U.S. dollar, changes in exchange control regulations, application of foreign tax laws, changes in governmental economic or monetary policy, or changed circumstances in dealings between nations. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information about issuers of foreign securities. In addition, foreign brokerage commissions, custody fees, and other costs of investing in foreign securities are often higher than in the United States. Investments in foreign issues could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, and potential difficulties in enforcing contractual obligations. In addition to the risks of foreign securities in general, countries in emerging markets are more volatile and can have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues which could reduce liquidity. There is also less publicly available information on emerging market companies due to differences in regulation, accounting, auditing, and financial recordkeeping requirements, and the information available may be unreliable or outdated.

COVID-19 Risk. An outbreak of infectious respiratory illness caused by a novel coronavirus known as COVID-19 was first detected in China in December 2019 and has now been detected globally. COVID-19 has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many countries or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. As such, issuers of debt securities with operations, productions, offices, and/or personnel in (or other exposure to) areas affected with the virus may experience significant disruptions to their business and/or holdings. The potential impact on the credit markets may include market illiquidity, defaults and bankruptcies, among other consequences, particularly on issuers in the airline, travel and leisure and retail sectors. The extent to which COVID-19 will affect the Fund, the Fund’s service providers’ and/or issuer’s operations and results will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19 and the actions taken to contain COVID-19. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic, political and/or financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected by such events. If there is a significant decline in the value of the Fund’s portfolio, this may impact the Fund’s asset coverage levels for certain kinds of derivatives and other portfolio transactions. The duration of the COVID-19 outbreak and its impact on the global economy cannot be determined with certainty.

Cybersecurity Risk. As part of its business, the Advisor processes, stores, and transmits large amounts of electronic information, including information relating to the transactions of the Fund. The Advisor and the Fund are therefore susceptible to cybersecurity risk. Cybersecurity failures or breaches of the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, and/or reputational damage. The Fund and its shareholders could be negatively impacted as a result.

Investment Advisor Risk. The Advisor’s ability to choose suitable investments has a significant impact on the ability of the Fund to achieve its investment objectives.

LIBOR Risk. Instruments in which the Fund invests may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. The Fund and issuers of instruments in which the Fund invests may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund and/or issuers of instruments in which the Fund may invest may also reference LIBOR. The Fund also may utilize leverage or borrowings primarily based on LIBOR. In July 2017, the head of the United Kingdom Financial Conduct Authority announced the desire to phase out the use of LIBOR by the end of 2021. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. Abandonment of or modifications to LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments that reference LIBOR. The effect of a phase out of LIBOR on U.S. instruments in which the Fund may invest is currently unclear. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments may have such provisions, and there is significant uncertainty regarding the effectiveness of any such alternative methodologies. Abandonment of or modifications to LIBOR could lead to significant short-term and long-term uncertainty and market instability. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally.

Market Risk. Market risk refers to the possibility that the value of securities held by the Fund may decline due to daily fluctuations in the market. Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general. The price of a security may even be affected by factors unrelated to the value or condition of its issuer, including changes in interest rates, economic and political conditions, and general market conditions. The Fund’s performance per share will change daily in response to such factors.

Portfolio Turnover Risk. The Advisor will sell Portfolio Funds and other securities when it is in the best interest of the Fund and its shareholders to do so without regard to the length of time they have been held. As portfolio turnover may involve paying brokerage commissions and other transaction costs, there could be additional expenses for the Fund. High rates of portfolio turnover may also result in the realization of short-term capital gains and losses. Any distributions resulting from such gains will be considered ordinary income for federal income tax purposes.

Preferred Equity Risk. Preferred equity’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred equity may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred equity tends to vary more with fluctuations in the underlying common equity and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred equity may suffer a loss of value if dividends are not paid and have limited voting rights.

U.S. Government Securities Risk. U.S. government securities risk refers to the risk that debt securities issued or guaranteed by certain U.S. Government agencies, instrumentalities, and sponsored enterprises are not supported by the full faith and credit of the U.S. Government, and so investments in their securities or obligations issued by them involve credit risk greater than investments in other types of U.S. Government securities.

The following bar chart and tables provide an indication of the risks of investing in the Fund by showing changes in the Fund’s Institutional Class Shares performance from year to year and by showing how the average annual total returns for each class compared to that of a broad-based securities market index. Performance information for Class A shares will be included after the share class has been in operation for one complete calendar year. Although Class A and Class C shares would have similar annual returns because they have the same total annual fund operating expenses, Class A and Class C shares average annual total returns would be lower than those shown for Institutional Class Shares in the table because Class A and Class C shares generally have higher expenses than Institutional Class Shares. Performance for the periods shown below prior to February 12, 2018, is based on the prior investment strategy utilized by the Fund. Prior to July 31, 2015, the Fund had a different investment advisor. The Fund changed its investment strategy effective October 1, 2020. Performance information for periods prior to October 1, 2020 does not reflect the Fund’s current investment strategy. The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future.
