The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.
The example assumes that you invest $10,000 in the Fund, your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the example incorporates the fee waiver and/or expense reimbursement arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the reporting period, the Fund did not hold any long-term investments and accordingly portfolio turnover is not applicable.
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in liquid, high quality U.S. dollar-denominated money market instruments of U.S. and foreign financial issuers and non-financial issuers. The Fund also invests in obligations issued or guaranteed by the U.S. Government and its agencies
and instrumentalities. The Fund’s money market investments may include commercial paper, corporate debt obligations, debt obligations (including certificates of deposit and promissory notes) of U.S. banks or foreign banks, or of U.S. branches or subsidiaries of foreign banks, or foreign branches of U.S. banks (such as Yankee obligations), certificates of deposit of savings banks and savings and loan organizations, asset-backed securities, repurchase agreements and municipal obligations.
Pursuant to a fundamental policy adopted by the Fund, the Fund invests, under normal circumstances, at least 25% of its total assets in securities issued by companies in the financial services industry, including banks, broker-dealers and insurance companies.
Securities purchased by the Fund (or the issuers of such securities) will carry a rating in the highest two rating categories, A-2, P-2 or F2 or better by S&P Global Ratings Group, a division of S&P Global Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”), or Fitch Ratings, Inc. (“Fitch”), respectively, or the equivalent by another nationally recognized statistical rating organization (“NRSRO”), or if unrated, considered by the Adviser to be of equivalent quality. The Fund may invest up to 5% of its assets, determined at the time of investment, in securities (or the issuers of such securities) rated A-2, P-2 or F2 by S&P, Moody’s or Fitch, respectively, and no more than 1% of its assets will be invested in an individual security or issuer with such rating. In the case of a security that is rated differently by these three rating agencies, where two rating agencies rate the security in the highest rating category and the third rating agency rates the security in the second highest rating category, the security will be treated as rated in the highest rating category. In the case of a security that is differently rated by only two of these rating agencies, the security will be treated as rated in the lower rating category.
Under normal circumstances, the Fund intends to maintain a maximum weighted average maturity of 90 days and a maximum weighted average life of 180 days.
The Fund is not a money market fund and does not seek to maintain a stable net asset value per share (“NAV”).
The Adviser follows a multi-pronged investment process with respect to credit risk, interest rate risk and liquidity. Securities are reviewed on an ongoing basis to maintain or improve creditworthiness taking into consideration factors such as cash flow, asset quality, debt service coverage ratios and economic developments. Additionally, exposure to guarantors and liquidity providers is monitored separately as are the various diversification requirements. The Adviser manages the Fund’s assets in an attempt to reduce credit and interest rate risks.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:
• Fixed-Income Securities. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk).
• Financial Services. The Fund is more susceptible to any economic, business, political, regulatory or other developments that adversely affect issuers in the financial services industry than a fund that does not concentrate its investments in the financial services industry. The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Financial services companies are also subject to extensive government regulation, including policy and legislative changes in the United States and other countries that are changing many aspects of financial regulation.
• Credit and Interest Rate Risk. Credit risk refers to the possibility that the issuer or guarantor of a security will be unable or unwilling or perceived to be unable to unwilling to make interest payments and/or repay the principal on its debt. In such instances, the value of the Fund could decline and the Fund could lose money. Interest rate risk refers to the decline in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). During periods when interest rates are low or there are
negative interest rates, the Fund’s yield (and total return) also may be low or otherwise adversely affected or the Fund may be unable to maintain positive returns. Credit ratings may not be an accurate assessment of liquidity or credit risk. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for a Fund to sell at an advantageous price or time.
• U.S. Government Securities. Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a U.S. government-sponsored entity, such as Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. With respect to U.S. government securities that are not backed by the full faith and credit of the United States, there is the risk that the U.S. Government will not provide financial support to such U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.
• Asset-Backed Securities. Asset-backed securities involve the risk that various federal and state consumer laws and other legal and economic factors may result in the collateral backing the securities being insufficient to support payment on the securities. Some asset-backed securities also entail prepayment risk and extension risk, which may vary depending on the type of asset.
• Repurchase Agreements. Repurchase agreements are subject to risks associated with the possibility of default by the seller at a time when the collateral has declined in value, or insolvency of the seller, which may affect the Fund’s right to control the collateral and result in certain costs and delays. Repurchase agreements may involve a greater degree of credit risk than investments in U.S. government securities.
• Foreign Money Market Securities. Investing in money market securities of foreign issuers involves some additional risks, including the possibility of adverse political, economic or other developments affecting the issuers of these securities.
• Municipals. Because the Fund may invest in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same economic sector, it could be more sensitive to economic, business or political developments that affect such sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy because of recent periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest.
• Liquidity. The Fund may make investments that are illiquid or restricted or that may become less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income mutual funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.
• LIBOR Discontinuance or Unavailability Risk. The London InterBank Offered Rate (“LIBOR”) is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. The regulatory authority that oversees financial services firms and financial markets in the U.K. has announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions for purposes of determining the LIBOR rate. However, subsequent announcements by the Financial Conduct Authority, the LIBOR administrator and other regulators indicate that it is possible that the most widely used tenors of U.S. Dollar LIBOR may continue to be provided on a representative basis until mid-2023. However, in connection with supervisory guidance from regulators, some regulated entities will cease to enter into most new LIBOR-based contracts after January 1, 2022. As a result, it is possible that commencing in 2022 (or on a later date, if a particular LIBOR tenor is expected to continue beyond the end of 2021), LIBOR may no longer be available or no longer deemed an appropriate reference rate upon which to determine the interest rate on or impacting certain loans, notes, derivatives and other instruments or investments comprising some or all of the Fund’s portfolio.
• Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. These events may be sudden and unexpected, and could adversely affect the liquidity of the Fund’s investments, which may in turn impact valuation, the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest) adversely interrupt the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These events may negatively impact broad segments of businesses and populations and have a significant and rapid negative
impact on the performance of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price and exacerbate pre-existing risks to the Fund.

Under normal circumstances, the Fund invests at least 80% of its net assets in municipal securities, the income from which is exempt from federal income tax. This policy is fundamental and may not be changed without shareholder approval. The Fund may also invest in variable and floating rate demand instruments and tender option bonds.
The Fund may invest up to 100% of its assets in municipal securities, the interest on which may be subject to the federal alternative minimum tax for individuals. In addition, the Fund may invest up to 20% of its assets in securities subject to federal income tax.
Securities purchased by the Fund (or the issuers of such securities) will carry a rating in the highest two rating categories, A-2, P-2 or F2 or better by S&P Global Ratings Group, a division of S&P Global Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch Ratings, Inc. (“Fitch”), respectively, or the equivalent by another nationally recognized statistical rating organization (“NRSRO”), or if unrated, considered by the Adviser to be of equivalent quality. The Fund may invest up to 15% of its assets, determined at the time of investment, in securities (or the issuers of such securities) rated A-2, P-2 or F2 by S&P, Moody’s or Fitch, respectively, and up to 5% of its assets in unrated securities. In the case of a security that is rated differently by these three rating agencies, where two rating agencies rate the security in the highest rating category and the third rating agency rates the security in the second highest rating category, the security will be treated as rated in the highest rating category. In the case of a security that is differently rated by only two of these rating agencies, the security will be treated as rated in the lower rating category.
Under normal circumstances, the Fund intends to maintain a maximum weighted average maturity of 90 days and a maximum weighted average life of 180 days. In addition, the Fund may only purchase securities with a maximum final maturity of two years.
The Fund is not a money market fund and does not seek to maintain a stable NAV.

Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for a Fund to sell at an advantageous price or time.
• U.S. Government Securities. Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a U.S. government-sponsored entity, such as Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, although
chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. With respect to U.S. government securities that are not backed by the full faith and credit of the United States, there is the risk that the U.S. Government will not provide financial support to such U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.
• Municipals. Because the Fund invests in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same economic sector, it could be more sensitive to economic, business or political developments that affect such sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy because of recent periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest.
• Tender Option Bonds. The risks of tender option bonds include the risk that the owner of such instrument may not be considered the owner for federal income tax purposes and thus will not be entitled to treat such interest as exempt from federal income tax. Additionally, the occurrence of certain defaults or a credit rating downgrade on the underlying security may impair the ability to tender the bond back to the third-party provider of the demand option, thus causing the bond to become illiquid.
• Taxability Risk. Changes in tax laws or adverse determinations by the Internal Revenue Service (“IRS”) may make the income from some municipal obligations taxable.
• Liquidity. The Fund may make investments that are illiquid or restricted or that may become less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income mutual funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.
• LIBOR Discontinuance or Unavailability Risk. The London InterBank Offered Rate (“LIBOR”) is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. The regulatory authority that oversees financial services firms and financial markets in the U.K. has announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions for purposes of determining the LIBOR rate. However, subsequent announcements by the Financial Conduct Authority, the LIBOR administrator and other regulators indicate that it is possible that the most widely used tenors of U.S. Dollar LIBOR may continue to be provided on a representative basis until mid-2023. However, in connection with supervisory guidance from regulators, some regulated entities will cease to enter into most new LIBOR-based contracts after January 1, 2022. As a result, it is possible that commencing in 2022 (or on a later date, if a particular LIBOR tenor is expected to continue beyond the end of 2021), LIBOR may no longer be available or no longer deemed an appropriate reference rate upon which to determine the interest rate on or impacting certain loans, notes, derivatives and other instruments or investments comprising some or all of the Fund’s portfolio.
• Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. These events may be sudden and unexpected, and could adversely affect the liquidity of the Fund’s investments, which may in turn impact valuation, the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest) adversely interrupt the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price and exacerbate pre-existing risks to the Fund.
