Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below.

ANNUAL FUND OPERATING EXPENSES (Expenses that you pay each year as a percentage of the value of your investment)
	Agency
Management Fees	0.08%
Distribution (Rule 12b-1) Fees	NONE
Other Expenses	0.19
Service Fees	0.15
Remainder of Other Expenses	0.04
Total Annual Fund Operating Expenses	0.27
Fee Waivers and/or Expense Reimbursements 1	-0.01
Total Annual Fund Operating Expenses after Fee Waivers and/or Expense Reimbursements 1	0.26

The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.26% of the average daily net assets of Agency Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 6/30/27, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Example

This Example 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 for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 6/30/27 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:

The Fund’s Main Investment Strategy

The Fund invests in high quality, short-term money market instruments which are issued and payable in U.S. dollars. The Fund principally invests in:

●

high quality commercial paper and other short-term debt securities, including floating and variable rate demand notes of U.S. and foreign corporations,

●

debt securities issued or guaranteed by qualified U.S. and foreign banks, including certificates of deposit, time deposits and other short-term securities,

●

securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or Government-Sponsored Enterprises (“GSEs”),

●

asset-backed securities,

●

repurchase agreements, and

●

taxable municipal obligations.

The Fund is a money market fund managed in the following manner:

●

The Fund calculates its net asset value to four decimals (e.g., $1.0000) using market-based pricing and operates with a floating net asset value.

●

The dollar-weighted average maturity of the Fund will be 60 days or less and the dollar-weighted average life to maturity will be 120 days or less.

●

The Fund will only buy securities that have remaining maturities of 397 days or less or securities otherwise permitted to be purchased because of maturity shortening provisions under applicable regulation.

●

The Fund invests only in U.S. dollar-denominated securities.

●

The Fund seeks to invest in securities that present minimal credit risk.

The Fund may invest significantly in securities with floating or variable rates of interest. Their yields will vary as interest rates change. The securities in which the Fund may invest include privately placed securities. The Fund will generally hold a portion of its assets in cash, primarily to meet redemptions.

The Fund will concentrate its investments in the banking industry. Therefore, under normal conditions, the Fund will invest at least 25% of its total assets in securities issued by companies in the banking industry. The Fund may, however, invest less than 25% of its total assets in this industry as a temporary defensive measure.

The Fund may trade securities on a when-issued, delayed settlement or forward commitment basis. The Fund’s adviser seeks to develop an appropriate portfolio by considering the differences in yields among securities of different maturities, market sectors and issuers.

Liquidity Fees

The Fund’s policies and procedures require the Fund to impose a mandatory liquidity fee if the Fund experiences total daily net redemptions (based on flow information available within a reasonable period after the last computation of the Fund’s net asset value on that day) exceeding 5% of net assets, unless the amount of the mandatory liquidity fee would be de minimis. The size of the mandatory liquidity fee to be charged will be based on a good faith estimate, supported by data, of the costs the Fund would incur if it sold a pro rata amount of each security in its portfolio to satisfy the amount of the net redemptions. If these costs cannot be determined in good faith, a 1% default fee will be applied. If the amount of the mandatory liquidity fee would be de minimis (i.e., less than 0.01% of the value of the shares redeemed), the Fund is not required to charge a mandatory liquidity fee. In addition, the Fund’s policies and procedures permit the Fund to impose a discretionary liquidity fee on redemptions of up to 2% of the value of the shares redeemed if the adviser, as the delegate of the Board, determines it is in the best interests of the Fund.

The Fund’s Main Investment Risks

The Fund is subject to management risk and the Fund may not achieve its objective if the adviser’s expectations regarding particular instruments or interest rates are not met.

You could lose money by investing in the Fund. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The Fund may impose a fee upon sale of your shares. Effective October 2, 2024, the Fund generally must impose a fee when net sales of Fund shares exceed certain levels. 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. 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.

Any gain resulting from the sale or exchange of Fund shares will be taxable as long-term or short-term gain, depending upon how long you have held your shares.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in 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 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 due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.

Credit Risk. The Fund’s investments are subject to the risk that issuers, guarantors and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In

addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.

Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk. Mortgage-related and asset-backed securities are subject to certain other risks, including prepayment and call risks. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of either rising or declining interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Additionally, asset-backed, mortgage-related and mortgage-backed securities are subject to risks associated with their structure and the nature of the assets underlying the securities and the servicing of those assets. Certain asset-backed, mortgage-related and mortgage-backed securities may face valuation difficulties and may be less liquid than other types of asset-backed, mortgage-related and mortgage-backed securities, or debt securities.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States, are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. Government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. Government-related organizations may not have the funds to meet their payment obligations in the future.

Municipal Obligations and Securities Risk. Because the Fund may invest in municipal obligations, including municipal securities, the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal obligations, such as state and local governments and

their agencies. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality’s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund’s income or hurt the ability to preserve capital and liquidity. In addition, budgetary constraints of state and local governments may lead to reduced tax revenues and may further limit their ability to service municipal obligations. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund’s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. In addition, changes in U.S. federal tax laws or the activity of an issuer may adversely affect the tax-exempt status of municipal obligations. Loss of tax-exempt status may result in a significant decline in the values of such municipal obligations.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the obligations and thus the value of the Fund’s investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund’s investments. There may be times that, in the opinion of the adviser, municipal money market securities of sufficient quality are not available for the Fund to be able to invest in accordance with its normal investment policies. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

When-Issued, Delayed Settlement and Forward Commitment Transactions Risk. The Fund may purchase or sell securities which it is eligible to purchase or sell on a when-issued basis, may purchase and sell such securities for delayed delivery and may make contracts to purchase or sell such securities for a fixed price at a future date beyond normal settlement time (forward commitments). When-issued transactions, delayed delivery purchases and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its

obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Concentration Risk. Because the Fund will, under ordinary circumstances, invest a significant portion of its assets in securities of companies in the financial services industry, developments affecting the financial services industry may have a disproportionate impact on the Fund. These risks generally include interest rate risk, credit risk and risk associated with regulatory changes in the financial services industry. In addition, financial services companies are highly dependent on the supply of short-term financing.

Foreign Securities Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, unstable governments, greater volatility, decreased market liquidity, civil conflicts and war, currency fluctuations, sanctions or other measures by the United States or other governments, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund's ability to buy and sell securities. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund’s shares may fluctuate in response to events affecting that industry or sector.

Floating and Variable Rate Securities Risk. Floating and variable rate securities provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may

be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time. Such securities also may lose value.

Repurchase Agreement Risk. There is a risk that the counterparty to a repurchase agreement will default or otherwise become unable to honor a financial obligation and the value of your investment could decline as a result.

Risk Associated with the Fund Holding Cash. The Fund will generally hold a portion of its assets in cash, primarily to meet redemptions. Cash positions may hurt performance and may subject the Fund to additional risks and costs, such as increased exposure to the custodian bank holding the assets and any fees imposed for large cash balances.

Prepayment Risk. The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency. It is possible to lose money by investing in the Fund.
