Prospectus [Line Items]  
Risk [Text Block] Market – Factors such as economic events, inflation, changes in interest rates, governmental actions or interventions, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by tariffs, trade disputes, labor strikes, supply chain disruptions or other factors, government shutdowns, political developments, civil unrest, acts of terrorism, armed conflicts, economic sanctions, countermeasures in response to sanctions, cybersecurity events, technological developments (such as artificial intelligence and machine learning), investor sentiment, the global and domestic effects of widespread or local health, weather or climate events, lack of liquidity or other disruptions in the bond markets, or other adverse market events and conditions could cause the value of your investment in the fund, or its yield, to decline. While the fund seeks to maintain a $1.00 share price, when market prices fall, the value of your investment in the fund could go down. Economies and financial markets throughout the world are increasingly interconnected. Events or circumstances in one or more countries or regions could be highly disruptive to, and have profound impacts on, global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the fund’s investments may go down. The long-term consequences to the U.S. economy of the continued expansion of U.S. government debt and deficits are not known. Also, raising the ceiling on U.S. government debt and periodic legislation to fund the government have become increasingly politicized. Any failure to do either could lead to a default on U.S. government obligations, with unpredictable consequences for the fund's investments and the fund's ability to preserve the value of your investment at $1.00 per share, and generally for economies and markets in the U.S. and elsewhere.
Government Money Market Fund [Member]  
Prospectus [Line Items]  
Risk [Text Block] Government Money Market Fund – The fund operates as a “government” money market fund under applicable federal regulations and invests in U.S. government securities. Circumstances could arise that would prevent the payment of interest or principal on U.S. government securities, which could adversely affect their value and the fund’s ability to preserve the value of your investment at $1.00 per share. An increased demand for U.S. government securities could affect the availability of such instruments for investment and the fund's ability to pursue its investment strategies. The fund does not currently intend to avail itself of the ability to impose “liquidity fees” on fund redemptions, as permitted under Rule 2a-7. However, the Board reserves the right, with notice to shareholders, to change this policy.
Interest Rate [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate – The interest rates on short-term obligations held in the fund will vary, rising or falling with short-term interest rates generally. The fund's yield will tend to lag behind general changes in interest rates. Changes in interest rates can be sudden and unpredictable and may expose the markets to significant volatility, which also may affect the liquidity of the fund’s investments and detract from fund performance. A variety of factors can impact interest rates, including central bank monetary policies and inflation rates. A general rise in interest rates may cause investors to sell fixed-income securities on a large scale, which could adversely affect the price and liquidity of fixed-income securities and could also result in increased redemptions from the fund. Inflation and interest rates have been volatile and may increase in the future. Interest rate increases in the future may cause the value of fixed-income securities to decrease and, conversely, interest rate reductions may cause the value of fixed-income securities to increase. During periods of extremely low or negative short-term interest rates, the fund may not be able to maintain a positive yield or total return or be able to preserve the value of your investment at $1.00 per share.
US Government Securities [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government Securities – U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities backed by the Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the financial condition or credit rating of the U.S. government. Notwithstanding that these securities are backed by the full faith and credit of the U.S. government, circumstances could arise that would prevent the payment of interest or principal. Securities issued by U.S. government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are not funded by congressional appropriations and the securities issued by them are neither issued nor guaranteed by the U.S. government.
Fixed Income Securities [Member]  
Prospectus [Line Items]  
Risk [Text Block] Fixed-Income Securities – Risks of fixed-income securities include credit risk, interest rate risk, counterparty risk, prepayment risk, extension risk, valuation risk, and liquidity risk. The value of fixed-income securities may go up or down, sometimes rapidly and unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, wars, social unrest, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the value of a fixed-income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. If the value of fixed-income securities owned by the fund falls, the value of your investment will go down. The fund may lose its entire investment in the fixed-income securities of an issuer.
Credit [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit – An issuer or other obligor (such as a party providing insurance or other credit enhancement) of a security held by the fund or a counterparty to a financial contract with the fund may be unable or unwilling to meet its financial obligations or may be perceived (whether by market participants, ratings agencies, pricing services or otherwise) to be less creditworthy, or the value of assets underlying a security may decline. A decline may be rapid and/or significant, particularly in certain market environments. In addition, the fund may incur costs and may be hindered or delayed in enforcing its rights against an issuer, obligor or counterparty.
Counterparty [Member]  
Prospectus [Line Items]  
Risk [Text Block] Counterparty – The fund could lose money if the counterparties to derivatives, repurchase agreements and/or other financial contracts entered into for the fund do not fulfill their contractual obligations. In addition, the fund may incur costs and may be hindered or delayed in enforcing its rights against a counterparty. These risks may be greater to the extent the fund has more contractual exposure to a counterparty.
Repurchase Agreements [Member]  
Prospectus [Line Items]  
Risk [Text Block] Repurchase Agreements – In a repurchase agreement, the fund purchases securities from a broker-dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the fund at a later date, and at a specified price. The securities purchased serve as the fund's collateral for the obligation of the counterparty to repurchase the securities. If the counterparty does not repurchase the securities, the fund is entitled to sell the securities, but the fund may not be able to sell them for the price at which they were purchased, thus causing a loss. If the counterparty becomes insolvent, there is some risk that the fund will not have a right to the securities, or the immediate right to sell the securities.
Extension [Member]  
Prospectus [Line Items]  
Risk [Text Block] Extension – When interest rates rise, payments of fixed-income securities, including asset- and mortgage-backed securities, may occur more slowly than anticipated, causing their market prices to decline.
Management [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management – The fund is subject to the risk that the investment manager’s or sub-adviser’s judgments and decisions may be incorrect or otherwise may not produce the desired results. The sub-adviser’s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or issuer, industry or sector, or about the economy or interest rates, may be incorrect. The fund is also subject to the risk of imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, or the analyses employed or relied on, by the sub-adviser, if such tools, resources, information or data are used incorrectly, fail to produce the desired results or otherwise do not work as intended, or if the sub-adviser’s investment style fails to produce the desired results. Any of these things could cause the fund to lag relevant benchmarks or other funds with similar objectives.
Active Trading [Member]  
Prospectus [Line Items]  
Risk [Text Block] Active Trading – The fund may engage in active trading of its portfolio. Active trading will increase transaction costs and could detract from performance. Active trading may be more pronounced during periods of market volatility and may generate greater amounts of short-term capital gains.
Cybersecurity [Member]  
Prospectus [Line Items]  
Risk [Text Block] Cybersecurity – Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or shareholder data (including private shareholder information), or proprietary information, cause the fund or its service providers (including, but not limited to, the fund’s investment manager, any sub-adviser(s), transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. Cybersecurity incidents may render records of fund assets and transactions, shareholder ownership of fund shares, and other data integral to the functioning of the fund inaccessible, inaccurate or incomplete. The use of artificial intelligence and machine learning could exacerbate these risks. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents.
Large Shareholder [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large Shareholder – A significant portion of the fund’s shares may be owned by one or more investment vehicles or institutional investors. Transactions by these large shareholders may be disruptive to the management of the fund. For example, the fund may experience large redemptions and could be required to sell securities at a time when it may not otherwise desire to do so. Such transactions may increase the fund’s brokerage and/or other transaction costs. These transactions may also accelerate the realization of taxable capital gains to shareholders. In addition, sizeable redemptions could cause the fund’s total expenses to increase.
Liquidity [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity – The fund may make investments that are illiquid or that become illiquid after purchase. Illiquid investments can be difficult to value, may trade at a discount from comparable, more liquid investments, and may be subject to wide fluctuations in value. Liquidity risk may be magnified in rising interest rate or volatile environments. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a substantial loss or may not be able to sell at all. Liquidity of particular investments, or even entire asset classes, including U.S. Treasury securities, can deteriorate rapidly, particularly during times of market turmoil, and those investments may be difficult or impossible for the fund to sell. This may prevent the fund from limiting losses.
Redemption [Member]  
Prospectus [Line Items]  
Risk [Text Block] Redemption – The fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value. Redemption risk is greater to the extent that the fund has investors with large shareholdings, short investment horizons, or unpredictable cash flow needs. The redemption by one or more large shareholders of their holdings in the fund could have an adverse impact on the remaining shareholders in the fund. In addition, the fund may suspend redemptions when permitted by applicable regulations.
Underlying Government Money Market Funds [Member]  
Prospectus [Line Items]  
Risk [Text Block] Underlying Government Money Market Funds – The fund may invest in other government money market funds. Each of the underlying government money market funds in which the fund may invest has its own investment risks. There can be no assurance that the investment objective of any underlying government money market fund will be achieved. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying government money market funds in which it invests.
Yield [Member]  
Prospectus [Line Items]  
Risk [Text Block] Yield – The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and the fund’s expenses could absorb all or a significant portion of the fund’s income. If interest rates increase, the fund’s yield may not increase proportionately.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money by investing in the fund.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Risk Money Market Fund May Not Preserve Dollar [Member]  
Prospectus [Line Items]  
Risk [Text Block] Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.
Risk Money Market Fund Sponsor May Not Provide Support [Member]  
Prospectus [Line Items]  
Risk [Text Block] The fund’s sponsor is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.
