Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of a Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund, Wisconsin Capital Management, LLC (the Fund’s investment advisor), the Fund’s distributor, or any of their respective affiliates may pay the intermediary for the sale of the Fund’s shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial adviser to recommend the Funds over another investment. Ask your individual financial adviser or visit your financial intermediary’s website for more information.

INVESTMENT OBJECTIVES, PRINCIPAL INVESTMENT STRATEGIES AND RELATED RISKS

This section of the Prospectus describes the Funds’ investment objectives and strategies and the risks of investing in the Funds. The investment objectives of the Funds can be changed without shareholder approval.

Investment Objectives and Principal Investment Strategies

Balanced Fund:

Investment Objective

The Balanced Fund seeks a high total return through capital appreciation while attempting to preserve principal, and secondarily seeks current income.

Principal Investment Strategies

The Balanced Fund invests in a diversified portfolio of common stocks and fixed income securities. We select securities that, in our judgment, will result in the highest total return consistent with preservation of principal, and we vary the mix of common stocks and bonds from time to time. More than 50% of the Fund’s assets are normally invested in common stocks. In allocating the Fund’s assets between stocks and bonds, we assess the relative return and risk of each asset class, analyzing several factors, including general economic conditions, anticipated future changes in interest rates, and the outlook for stocks generally. The Fund will also invest in foreign securities, including the securities of companies located in emerging market countries. The Fund will limit its investments in foreign securities, including in American Depositary Receipts (“ADRs”), to 15% of its total assets. The Fund will only invest in emerging-market securities to the extent that such securities are listed on a U.S. exchange.

To achieve a better risk-adjusted return on its equity investments, the Fund invests in many types of stocks, including a blend of large company stocks, smaller company stocks, growth stocks, and value stocks. We believe that holding a diverse group of stocks will provide competitive returns under different market environments, as opposed to more narrow investment styles. Our flexible approach to equity investing enables us to adapt to changing market trends and conditions and to invest where we believe opportunity exists.

We also normally invest at least 25% of the Fund’s assets in fixed income senior securities. The fixed income senior securities in which the Fund may invest include corporate bonds and other debt instruments, mortgage-related securities, asset-backed securities, debt securities issued or guaranteed by the U.S. Government (including its agencies and instrumentalities), convertible debt securities, and preferred stock. In addition to their fixed income characteristics, some of these securities may be convertible into common stock of the issuing corporation. The dollar-weighted average portfolio maturity of the fixed income securities held by the Fund will normally not exceed 10 years.

Other Investment Strategies

The Balanced Fund typically invests in common stocks that possess most of the following characteristics:

The Balanced Fund generally invests in investment-grade fixed income securities, although it may invest up to 5% of its total assets in securities rated below investment grade (i.e., high-yield or “junk” bonds). Under adverse market conditions, the Balanced Fund could invest a substantial portion of its assets in U.S. Treasury securities and money market securities.

Equity Fund:

Investment Objective

The Equity Fund seeks long-term capital appreciation.

Principal Investment Strategies

To pursue its investment objective, the Fund normally invests at least 80% of its assets, including borrowings for investment purposes, in common stocks and other equity securities. The Fund generally invests in stocks encompassing small, medium, and large market capitalizations. The Fund focuses on companies with growth rates higher than the general United States economy and with the potential to benefit from either secular macroeconomic trends or the creation of a new total addressable market (TAM).

The Fund will also invest in foreign securities, including the securities of companies located in foreign countries. The Fund will limit its investments in foreign securities, typically in American Depositary Receipts (ADRs), to 15% of its total assets. The Fund will only invest in foreign domiciled securities to the extent that such securities are listed on a U.S. exchange.

The Fund seeks to provide investors with competitive after-tax investment returns by holding quality securities for the long term, which is designed to promote greater tax efficiency.

The Fund typically sells securities in companies if the investment thesis is changing or for opportunity cost, meaning we believe another security is more attractive for our shareholders. This typically occurs when the market valuation of a security held by the Fund rises significantly above the portfolio managers’ estimates of its intrinsic business value or when the portfolio managers perceive that long-term economic fundamentals have significantly deteriorated or are unlikely to match their initial expectations.

Other Investment Strategies

The portfolio managers of the Equity Fund typically looks for companies that possess the following characteristics:

Under adverse market conditions, the Equity Fund could invest a substantial portion of its assets in U.S. Treasury securities and money market securities.

Principal Investment Risks

Balanced Fund:

The stock and bond markets can perform differently from each other at any given time (as well as over the long term), so the Balanced Fund will be affected by its asset allocation. If the Fund favors an asset class during a period when that class underperforms, performance may be hurt. The Fund’s principal risks are discussed below. The value of your investment in the Fund will fluctuate, sometimes dramatically, which means you could lose money.

threatened or actual imposition of tariffs. Drastically reduced or volatile trading activity may make it difficult for the Fund to properly value its investments, particularly its fixed-income investments.

The Balanced Fund’s investments in stocks and other equity securities are subject to the following additional principal risks:

The Balanced Fund’s investments in bonds and other fixed-income securities are subject to the following additional principal risks:

Equity Fund:

The Equity Fund’s principal risks are discussed below. The value of your investment in the Fund will fluctuate, sometimes dramatically, which means you could lose money.

Other Non-Principal Investment Risks of the Funds

on the Funds cannot be predicted with certainty. This uncertainty is likely to amplify other risks that apply to the Funds.

Temporary strategies in which the Funds may engage from time to time expose them to certain other risks described below.

Portfolio Holdings

A description of the Funds’ policies and procedures with respect to the disclosure of the Funds’ portfolio securities is available in the Funds’ Statement of Additional Information. The Funds’ Portfolio Holdings Disclosure Policy is also available and on their website (www.plumbfunds.com).

MANAGEMENT

Investment Advisor

Wisconsin Capital Management, LLC, 8020 Excelsior Drive, Suite 402, Madison, Wisconsin 53717, (the “Advisor”) serves as investment advisor to the Funds. As of June 30, 2026, the Advisor had assets under discretionary management of approximately $292 million.

The Advisor manages the investment of each Fund’s assets; provides each Fund with personnel, facilities, and administrative services; and supervises each Fund’s daily business affairs, all subject to the oversight of the Board of Directors. Under the investment advisory agreement pursuant to which the Advisor provides advisory services, each Fund pays the Advisor a fee at an annual rate equal to 65 basis points (0.65%) of the Fund’s average daily net assets.

From time to time, the Advisor may waive fees paid to it by a Fund and/or pay other Fund ordinary operating expenses (excluding brokerage commissions, interest, and taxes) to the extent necessary to ensure that such Fund’s total annual ordinary operating expenses do not exceed a certain percentage of average net assets. Waivers and reimbursements have the effect of lowering a Fund’s overall expense ratio and increasing a Fund’s overall return to investors. The Advisor has contractually agreed, at least until July 31, 2027, to waive fees and reimburse expenses of each Fund so as to cap each Fund’s annual operating expense ratio (excluding Acquired Fund Fees and Expenses) at:

Each expense cap may not be terminated prior to this date except by the Board of Directors.

The annual investment advisory fee paid to the Advisor as a percentage of average daily net assets for the year ended March 31, 2026, net of expense reimbursements or fee waivers or recoupments (if applicable), was 0.55% for the Balanced Fund and 0.02% for the Equity Fund.

TGP, Inc., which is wholly and directly owned by Thomas G. Plumb, holds all of the voting units of the Advisor. The address of TGP, Inc. is the same as the Advisor’s address.

A discussion regarding the basis for the Funds’ Board of Directors approving the investment advisory agreement is available in the Funds’ Form N-CSR for the period ended September 30 and at www.plumbfunds.com.

The Statement of Additional Information (the “SAI”) provides additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers, and the portfolio managers’ ownership of shares in the Funds.

Rule 12b-1 Plan

Each Fund has adopted a distribution plan (the “Rule 12b-1 Plan”) which, among other things, requires it to pay Ultimus Fund Distributors, LLC (the “Distributor”), the principal underwriter and distributor of shares of the Funds, a monthly fee of up to 0.25% of its average daily net assets attributable to Investor Shares computed on an annual basis.

The amounts paid under the Rule 12b-1 Plan reimburse the Distributor for distributing Investor Shares of the Funds and providing services to shareholders. Covered distribution expenses include, but are not limited to, the printing of prospectuses and reports used for sales purposes, advertisements, expenses of preparation and printing of sales literature, expenses associated with electronic marketing and sales media and communications, and other sales or promotional expenses, including compensation paid to any securities dealer (including the Distributor), financial institution, or other person that renders assistance in distributing or promoting the sale of Investor Shares of the Funds, provides shareholder services to the Funds, or that has incurred any of the aforementioned expenses on behalf of the Funds pursuant to a Dealer Agreement or other authorized arrangement. Covered shareholder servicing expenses include, but are not limited to, costs associated with relationship management, retirement plan enrollment meetings, investment and educational meetings, conferences and seminars, and the cost of collateral materials for such events. A Fund is obligated to pay fees under the Rule 12b-1 Plan only to the extent of expenses actually incurred by the Distributor for the current year, and thus there will be no carry-over expenses from previous years. No fee paid by one Fund under the Rule 12b-1 Plan may be used to reimburse the Distributor for expenses incurred in connection with its provision of distribution or shareholder services to another Fund. Because these fees are paid out of the Funds’ assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

The Funds’ Rule 12b-1 Plan also authorizes the Funds to pay covered distribution and servicing expenses directly rather than through the Distributor, subject to the requirement that the aggregate amounts paid directly and to the Distributor do not exceed 0.25% per annum of the particular Fund’s average daily net assets attributable to Investor Shares of that Fund. The Funds’ direct payment of covered distribution and servicing expenses is made with the Distributor’s knowledge primarily for administrative convenience.

Revenue Sharing

The Advisor expects to pay additional compensation out of its own assets (and not as an additional charge to any Fund) to selected financial advisors in connection with the retention and/or servicing of Fund investors and Fund shares, including without limitation for various shareholder servicing, recordkeeping or other services with respect to the Funds. Receipt of, or the prospect of receiving, this additional compensation, may influence your financial advisor’s recommendation of the Funds. Please see the SAI for more information about the Advisor’s use of this additional compensation.

The Advisor expects to pay out of its own resources (and not as an additional charge to a Fund) compensation to certain financial intermediaries in connection with the sale and distribution of the Funds’ shares and the retention and servicing of Fund investors who own the Funds’ shares. These payments are sometimes referred to as “revenue sharing” payments and are payments separate

from any service fees or other expenses paid by the Funds and described elsewhere in this Prospectus. Through this arrangement, financial intermediaries may assist the Advisor in developing and structuring marketing initiatives, creating marketing materials, attending sales meetings, and placing the Funds’ shares on a financial intermediary’s list of mutual funds available for purchase by the intermediary’s clients. Fees payable under this marketing agreement, which may be substantial, are negotiated between the parties.

HOW TO BUY SHARES

General

The price you pay for the shares will be the net asset value per share, determined at the end of the business day your purchase order is received by the Plumb Funds through Ultimus Fund Solutions, LLC, the Funds’ transfer agent (the “Transfer Agent”), or received by the Distributor, or other broker-dealers authorized by the Funds or their designated intermediaries. The Distributor and the Funds reserve the right to reject any purchase order for any reason. The Funds reserve the right to waive or change minimum initial and additional investment amounts. Shares generally may not be purchased by persons residing outside the United States. Please note that your application will be returned if any information is missing. The Funds do not issue share certificates.

Please call us at 1-866-987-7888 if you have any questions about purchasing shares of the Funds or require additional assistance in completing your Account Application.

The investment minimums for purchases of shares of the Funds (subject to any waiver or change by the Distributor or the Funds) are as follows:

The Funds reserve the right to waive the minimum initial investment amount at their discretion. The Funds do waive the minimum initial investment for Institutional Shares for employees and officers, and families of employees and officers, of the Advisor and its affiliates, and directors and officers of the Funds.

Important Information About Procedures for Opening a New Account

To help the government fight the funding of terrorism and money laundering activities, federal law requires financial institutions, including mutual funds, to obtain, verify, and record information that identifies each person or entity that opens an account, to the extent reasonable and practicable. This notice is provided in accordance with the USA PATRIOT Act of 2001 and the regulations issued thereunder.

What this means for you: When you open an account, the Funds and/or its agents (including the Transfer Agent) will request your full name, residential or business street address (a P.O. Box is not sufficient and will not be accepted as a primary address), date of birth (for individuals), and

an identification number, such as a Social Security Number or Taxpayer Identification Number (“TIN”), and may request other information that will allow the Fund to identify you.

For legal entities, the Funds may require documentation verifying the legal existence of the entity and, as required by applicable law, identifying and verifying the identity of beneficial owners and/or control persons. The Funds may also request to see a driver’s license, passport, or other identifying documents. The Funds may also check customer information against government lists, as required or permitted by applicable law. The Fund will retain records of the information used to verify identity in accordance with applicable law.

Verification Process: The Funds and/or its agents reserve the right to:

Purchase Procedures

Purchase Requests in Good Order

A purchase request will be considered to be in “good order” only if it includes all of the following:

Requests that are incomplete, unclear, or submitted without the required documentation may be delayed or rejected. The Funds and Transfer Agent are not responsible for delays or losses due to requests that are not received in good order.

Payment for Shares and Good Funds Policy

Online purchase transactions are subject to the requirements and limitations described under “Electronic Services and Online Account Transactions.”

Exchange of Fund Shares

You may exchange shares of the same class of one Plumb Fund for shares in an identically registered account of another Plumb Fund without a fee or sales charge. The exchange of shares can be made by mailing a letter of instruction to the Fund or by telephone unless you have declined this option on your Account Application. If an account has more than one owner or authorized person, telephone instructions will be accepted from any one owner or authorized person. In making telephone exchanges, you assume the risk for unauthorized transactions. However, we have procedures designed to reasonably assure that the telephone instructions are genuine and will be liable to you if you suffer a loss from our failure to abide by these procedures. The exchange privilege may be modified or terminated at any time.

The basic rules for exchanges are as follows:

Exchange requests may be submitted by written instruction or by telephone, unless telephone exchange privileges have been declined on your Account Application. If an account has more than one owner or authorized person, exchange instructions may be accepted from any one owner or authorized person.

All exchange requests must be received in good order and are subject to the applicable requirements of the receiving Funds and the Funds’ policies and procedures, including any applicable investment minimums, account registration requirements, holding periods, minimum balance requirements, frequency limitations, and other operational requirements established by the Funds or their transfer agent. The Funds reserve the right to reject any exchange request that is not received in good order.

Automatic Exchange Plan. You may also make regular monthly exchanges from the same class of one Plumb Fund to another through our Automatic Exchange Plan. You may participate in the Automatic Exchange Plan by contacting the Funds in writing. You must establish an account for each Plumb Fund with at least $2,500 ($1,000 for IRAs) for Investor Shares, at least $2,500 ($1,000 for IRAs) for Institutional Shares (unless your account type does not require an investment minimum with respect to Institutional Shares) and before you can make automatic exchanges. You determine the amount that will be automatically exchanged (must be at least $50) and the day of each month the exchange will be made.

Tax Treatment for Exchanges. An exchange of shares is generally treated as a redemption of shares from one Fund and a purchase of shares of another Fund. Accordingly, an exchange may result in a taxable gain or loss for federal, state, or local income tax purposes. Shareholders should consult their tax advisors regarding the tax consequences of exchanges in their particular circumstances.

HOW TO SELL SHARES

General

You may redeem all or some of your shares of the Funds at any time by submitting a redemption request in good order. A Redemption Request Form is available from the Funds. Please call the Funds at 1-866-987-7888 if you have any questions about redeeming shares.

The redemption price will be the net asset value (“NAV”) per share next determined after the redemption request is received in good order by the Transfer Agent, the Distributor, or another financial intermediary authorized by the Funds to receive redemption requests. The NAV per share is generally determined as of the close of regular trading on the New York Stock Exchange, typically 4:00 p.m. Eastern Time, on each day that the Exchange is open for trading.

A redemption request will be deemed in proper form if it includes:

Please see “Signature Guarantees” below for additional information regarding when a Medallion Signature Guarantee may be required.

Redemption requests that are incomplete, unclear, unsigned, or submitted without the required documentation or signature guarantees may be delayed or rejected. The Fund and its transfer agent are not responsible for processing delays or losses resulting from requests not received in good order.

Redemption Procedures

You may redeem Fund shares in the following ways:

Redemption Requests in Good Order

A redemption request will be considered to be in “good order” only if it includes all of the following:

Redemption requests that are incomplete, unclear, unsigned, or submitted without the required documentation or signature guarantees may be delayed or rejected. The Funds and Transfer Agent are not responsible for processing delays or losses resulting from requests not received in good order.

Online redemption transactions are subject to the requirements and limitations described under “Electronic Services and Online Account Transactions.”

Receiving Redemption Proceeds

You may receive proceeds of your redemption by check, ACH, or federal wire transfer. The Funds typically expect that it will take one-to-three days following the receipt of your redemption request to pay out redemption proceeds; however, while not expected, payment of redemption proceeds may take up to seven days. The Funds typically expect that they will hold cash or cash equivalents to meet redemption requests. The Funds may also use the proceeds from the sale of portfolio securities to meet redemption requests if consistent with the management of the Fund. These redemption methods will be used regularly and may also be used in stressed market conditions. No redemption will be effective until all necessary documents have been received in proper form by the Plumb Funds (through the Transfer Agent). Before selling recently purchased shares, please note that if the Transfer Agent has not yet collected payment for the shares you are selling, it may delay sending the proceeds until the payment is collected, which may take up to 15 calendar days from the purchase date. This delay will not apply if you purchased your shares via wire payment.

Other Redemption Information

Medallion Signature Guarantee (“MSG”) Requirements. To protect shareholders and the Fund from potential fraud, the Fund and/or its transfer agent (the “Transfer Agent”) may require a signature guarantee, including a Medallion Signature Guarantee (“MSG”), in certain circumstances. An MSG is a stamped certification from an eligible guarantor institution that verifies the authenticity of a signature and the authority and capacity of the person signing. A Fund or its transfer agent may require a Medallion Signature Guarantee in the following situations:

In addition to the situations described above, the Funds and/or the Transfer Agent may require a signature guarantee under other circumstances as indicated. Additionally, the Funds reserve the right to waive any signature requirement at their discretion.

Medallion Signature Guarantees must be obtained from eligible guarantor institutions that are members of a Medallion Signature Guarantee program recognized by the Securities Transfer Association (e.g., STAMP, SEMP, or MSP). These typically include commercial banks, savings associations, credit unions, and broker-dealers. Notarization is not an acceptable substitute for a Medallion Signature Guarantee.

Shareholders should contact the Funds’ transfer agent in advance of submitting any transaction requests if they are uncertain whether a Medallion Signature Guarantee is required.

Non-financial transactions, including establishing or modifying certain services on an account, may require a signature guarantee, signature verification from a Signature Validation Program member, or other form of authentication from a financial institution source that is acceptable to the Funds.

Shareholders should contact the Transfer Agent in advance if they are unsure whether an MSG will be required. The Fund and/or the Transfer Agent reserves the right, in its discretion, to waive or require an MSG and to reject any signature guarantee that it deems unacceptable.

Small Accounts. We reserve the right to terminate your account(s) in the Funds if, as a result of any transfer, exchange, or redemption of shares in the account, the aggregate value of all of your accounts with the Funds falls below $2,000. We will notify you at least 30 days in advance of our intention to terminate any account to allow you an opportunity to restore the account balance to at least $2,000. Upon any such termination, we will send you a check for the proceeds of redemption.

Suspension of Redemptions. The right of redemption may be suspended or the date of payment postponed: (a) when trading on the New York Stock Exchange (“NYSE”) is restricted, as determined by applicable rules and regulations of the SEC; (b) when the NYSE is closed for other

than customary weekend and holiday closings; (c) when the SEC has by order permitted such suspension; or (d) during an emergency, as determined by the SEC, as a result of which it is not reasonably practicable for the Fund to dispose of securities or to determine the value of its net assets.

Excessive Account Activity. An excessive number of purchases, exchanges, and redemptions by a shareholder (market timing) in and out of a Fund may be disadvantageous to the Fund and its shareholders. Frequent transactions present risks to Fund shareholders such as dilution in the value of Fund shares held by long-term holders, interference with the efficient management of the Fund’s portfolio, increased brokerage and administrative costs, and adverse tax consequences. The Funds’ Board of Directors has adopted policies to discourage frequent purchases, exchanges, and redemptions of Fund shares. We seek to prohibit any shareholder from making, during any 12-month period, more than three purchases back into a Fund that were preceded by or otherwise associated with exchanges or redemptions from the Fund. However, when purchases, exchanges, and redemptions are made through omnibus accounts maintained by broker-dealers and other intermediaries, we may not be able to effectively identify and restrict persons who engage in such activity. This prohibition does not apply to shareholders who have automatic investment plans or systematic withdrawal plans. We also reserve the right to revise or terminate the exchange privilege, limit the amount of an exchange or purchase order, or reject an exchange or purchase, at any time, for any reason. We also have the right to close accounts of persons who have a known history of market timing and other disruptive transaction activity.

Telephone Trades. Telephone exchange and redemption requests are subject to the requirements and limitations described under “Telephone Transactions.” Telephone instructions must be received in good order before the applicable cut-off time. Once a telephone transaction has been placed, it cannot be canceled or modified after the close of regular trading on the NYSE, generally 4:00 p.m. Eastern Time.

Verification of Shareholder Transaction Statements. You will receive periodic account statements summarizing all account activity, including purchases, redemptions, exchanges, and any reinvested dividends or capital gains. Additionally, a transaction confirmation will be sent for each financial transaction that occurs in your account, except for those taking place on a recurring basis, such as through an automatic investment plan or for dividend and capital gain distributions. For recurring transactions, the details will appear on your periodic account statement, serving as confirmation for such activity.

It is your responsibility to carefully review all transaction confirmations and account statements for accuracy immediately upon receipt. You must contact the Fund or its Transfer Agent in writing or by telephone promptly within 60 days of the date of the statement or confirmation that first reflects the disputed item. If you fail to provide timely notification within this 60-day period, you will be

deemed to have ratified all account activity set forth therein, and the Fund and its agents will not be liable for any losses that may result from your failure to report the issue.

Taxes. For tax purposes you will generally recognize a gain or loss for federal, state and local income tax purposes on a redemption of shares in the Fund. If you repurchase shares in the Fund within a 30-day period, the ability to recognize a loss for tax purposes may be limited by the wash-sale rules.

OTHER INFORMATION

Choosing a Share Class

Each Fund offers Institutional Shares and Investor Shares, through this prospectus. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different expenses and may have different share prices as outlined below. You should always discuss the suitability of your investment with your financial intermediary or financial advisor.

As noted in the table above, each Fund’s Investor Shares are subject to a Rule 12b-1 Plan fee of up to 0.25% of the average daily net assets based on the average daily net assets of the Fund’s Investor Shares as described herein. Because the minimum initial investment amount for Investor Shares and Institutional Shares is the same and because Institutional Shares are not subject to a Rule 12b-1 Plan fee, Institutional Shares generally will be a less expensive investment option than Investor Shares.

Institutional Shares

Institutional Shares are offered for sale at net asset value (“NAV”) without the imposition of a sales charge or shareholder servicing fee. Institutional Shares are offered primarily to institutions such as pension and profit sharing plans, employee benefit trusts, endowments, foundations, corporations and high net worth individuals. Institutional Class shares may also be offered through certain financial intermediaries that charge their customers transaction or other distribution or service fees with respect to their customers’ investments in the Funds. Pension and profit sharing plans, employee trusts and employee benefit plan alliances and “wrap account” or “managed fund” programs established with broker-dealers or financial intermediaries that maintain an omnibus or pooled account for the Funds and do not require the Funds to pay a fee, may purchase Institutional Shares, subject to investment minimums. The minimum initial investment for Institutional Shares of each Fund is $2,500 and may be waived or changed by a Fund in its sole discretion.

Investor Shares

Investor Shares are offered for sale at NAV, without the imposition of a sales charge. Investor Shares are subject to a Rule 12b-1 Plan fee up to 0.25% of the average daily net assets of a Fund attributable to Investor Shares, computed on an annual basis. The minimum initial investment for Investor Shares is $2,500 and may be waived or changed by a Fund in its sole discretion.

Determination of Net Asset Value

Each Fund determines the net asset value (“NAV”) per share with respect to each class of shares daily by adding the total value of the Fund’s investments and other assets, subtracting its liabilities, and dividing the result by the number of outstanding shares of the Fund. The NAV per share is calculated each business day, Monday through Friday, except on customary national business holidays when the New York Stock Exchange (“NYSE”) is closed or on any other day when the NYSE is closed. The calculation is made as of 4:00 p.m. Eastern Time.

For purposes of determining NAV, each Fund values its investments using market quotations when readily available. When market quotations are not readily available or are deemed unreliable for a security, the security is valued in good faith at its fair value in accordance with pricing policies and procedures adopted by the Funds’ Board of Directors.

Market quotations are readily available in nearly all instances for the common stocks and other equity securities in which the Funds invest. Therefore, in most cases, a Fund’s investments in equity securities will be valued using market quotations. However, an equity security may be priced at its fair value when the exchange on which the security is principally traded closes early, when trading in the security was halted during the day and did not resume prior to the Fund’s NAV calculation, or if the security is not traded on an exchange. A Fund may also value a security at fair value if a significant event materially affecting the security’s value occurs after its market price has been determined but before the Fund’s NAV is calculated.

Market quotations for debt securities and tax-exempt obligations held in the Balanced Fund are often not readily available. Fair values of debt securities are typically based on valuations published by an independent pricing service. Debt securities purchased by a Fund with remaining maturities of 60 days or less are generally valued at the Fund’s cost, plus or minus any amortized discount or premium.

Whenever a security is priced at fair value, the Fund considers the relevant facts and circumstances set forth in the pricing policies and procedures adopted by the Funds’ Board of Directors and other factors as warranted. Factors that may be considered include, among others, the type of security; events or circumstances relating to the security’s issuer; general market conditions; size of the Fund’s holding in the security; prior valuations and trading activity; cost of the security when it was purchased; and restrictions on disposition.

Fair value pricing is an inherently subjective process, and no single standard exists for determining fair value. Different funds could reasonably arrive at different values for the same security. There is no guarantee that the fair value assigned to a particular security will actually be realized upon a sale of that security.

Because different expenses are charged to Investor Shares and Institutional Shares, the NAV of the two classes of the Fund is expected to vary.

Authorized Broker-Dealers

The Funds have authorized one or more broker-dealers to receive purchase and redemption orders on behalf of each Fund. These broker-dealers may designate other intermediaries to receive such orders. These authorized broker-dealers may charge customers a fee for their services. The Funds will be deemed to have received a customer order when an authorized broker-dealer or its designated intermediary receives the order. Such customer orders will be priced at the particular Fund’s net asset value per share next determined after the orders are received by an authorized broker-dealer or its designated intermediary.

Dividends and Distributions

Each Fund annually distributes substantially all of its net investment income and any net realized capital gains. These distributions are automatically reinvested in additional shares of the applicable class of the applicable Fund at the net asset value on the payment date, unless you request payment in cash on your account application. You may change your distribution option by writing or calling the transfer agent. Any change should be received by the transfer agent at least 5 days prior to the next distribution.

If you elect to receive distributions and dividends by check and the post office cannot deliver the check, or if the check remains uncashed for six months, we reserve the right to reinvest the distribution check in your account at the particular Fund’s then current net asset value per share. We will continue to reinvest all subsequent distributions in shares of the Fund until an updated address is received.

Taxes

Distributions of income and capital gains are generally taxable when they are paid whether they are reinvested in additional Fund shares or received in cash, unless you are exempt from taxation or hold the Funds through tax-deferred arrangements, such as 401 (k) plans or individual retirement accounts. Distributions are taxable as ordinary income, qualifying dividends, or capital gains. The maximum federal rate on long-term capital gains and qualifying dividends received by individuals, estates, and trusts is 20%, with an additional tax of 3.8% on net investment income of certain high-earning individuals, estates and trusts. Short-term capital gains distributions will be taxed as ordinary income. Qualifying dividends include dividends received from domestic corporations

(including mutual funds) on shares of stock that have been held for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date. Additional requirements and limitations are imposed for purposes of determining the amount of dividends received from mutual funds that may qualify for the reduced tax rate. Non-qualifying dividends, including dividends of income on debt securities, will be taxed at ordinary income rates. You will receive information annually on the federal tax status of your Fund’s dividends and capital gains distributions.

In the Account Application, you are asked to certify that your taxpayer identification or social security number is correct and that you are not subject to backup withholding. If you fail to provide your correct taxpayer identification or social security number, the Funds are required to withhold 24% of your taxable distributions and redemption proceeds.

Each Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and to take all other action required so that no federal income tax will be payable by such Fund itself. In order to qualify as a regulated investment company, each Fund must satisfy a number of requirements. If a Fund were to fail to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended, it would be treated as a Subchapter C corporation whose net taxable income (including taxable dividends and net capital gains) would be subject to income tax at the corporate level, and then distributions to shareholders of the remaining corporate after-tax income would be subject to tax at the shareholder level (i.e., double taxation).

The foregoing discussion of tax consequences is a general summary of some of the federal income tax considerations generally affecting each Fund and its shareholders and is based on federal tax laws and regulations in effect on the date of this Prospectus, which are subject to change by legislative or administrative action, with possible retroactive effect. Shareholders should consult their own tax advisors regarding the federal, state and local tax consequences of an investment in a Fund and the particular tax consequences to them of an investment in the Fund.

Cost Basis Reporting

The Funds are required to report to you and to the IRS the cost basis of your Fund shares acquired on or after January 1, 2012 (“covered shares”) when those shares are subsequently redeemed. Unless you elect a different permissible cost basis method in writing, the Funds will determine the cost basis of your covered shares using the average cost method. Please see the SAI for more information regarding cost basis reporting, including information about the average cost method.

You are encouraged to consult your tax advisor regarding the application of these cost basis reporting rules and, in particular, which cost basis calculation method you should elect. Representatives of the Funds are not tax advisors and are unable to give tax advice.

Please note that, in accordance with IRS regulations, the cost basis method elected for the first redemption of covered shares cannot be changed after the settlement of the redemption. The cost basis method you select may have significant tax implications. The Fund is not authorized to provide tax advice. We strongly recommend you consult your tax advisor to determine which method is most suitable for your individual circumstances.

Lost Shareholders, Inactive Accounts and Unclaimed Property

Unclaimed property laws may require the Fund or its transfer agent to transfer the assets of accounts that are considered abandoned, inactive, or lost (due to returned mail) to the appropriate state authority. An account may be deemed unclaimed if the shareholder has not initiated any contact or transaction within a time period specified by applicable state law.

Before any transfer to the state is made, the Fund or its transfer agent will send a due diligence notice to the shareholder, if legislatively required.

In some cases, this process is referred to as escheatment, and shareholders may be required to reclaim the assets from the applicable state’s unclaimed property office. Some states may also require the liquidation of shares prior to escheatment, and shareholders may only be entitled to receive the cash value at the time of sale.

For retirement accounts, such escheatment may be treated as a taxable distribution, and federal and/or state income tax withholding may apply.

To help avoid escheatment, shareholders should maintain current contact information and periodically initiate contact with the Fund or its transfer agent. Examples of shareholder-initiated contact include written correspondence, telephone inquiries, or initiating a transaction in the account.

If you are a resident of the state of Texas, you may designate a representative to receive notifications that, due to inactivity, your mutual fund account assets may be delivered to the Texas Comptroller. Please contact the Transfer Agent if you wish to complete a Texas Designation of Representative form.

Retirement Accounts and Plans

Individual Retirement Accounts. The Funds sponsor Individual Retirement Accounts (IRAs) through which you may invest annual IRA contributions and roll-over IRA contributions in shares of the Funds. The IRAs available through the Funds include Traditional IRAs, Roth IRAs, and Coverdell Education Savings Accounts. U.S. Bank National Association will serve as custodian for all IRA accounts sponsored by the Funds. U.S. Bank National Association will charge a $25.00 annual maintenance fee for each Traditional IRA, Roth IRA, or Coverdell Education Savings Account. Shareholders with two or more IRAs using the same tax ID number will be charged a total of $30.00 annually. Please refer to the IRA Disclosure Statement for a detailed listing of other fees. The Individual Retirement Account Custodial Agreement, the IRA Disclosure Statement, and the Custodial Account Application are available from the Funds.

Purchases and redemptions of shares of the Funds by IRAs and retirement plans are treated in the same manner as any other account. IRAs must meet a minimum initial investment requirement of $1,000 for Investor Shares and $1,000 for Institutional Shares (unless your account type does not require an investment minimum with respect to Institutional Shares).

Distributions from IRAs and other retirement accounts may be subject to federal income tax withholding and, where applicable, state income tax withholding. Federal income tax generally will be withheld from IRA distributions unless you elect otherwise on the applicable request form. If you do not make a withholding election, withholding will be applied in accordance with applicable law and IRS rules. State income tax withholding may also apply depending on your state of residence and applicable state law. Withholding is not a determination of your actual tax liability.

Shares held in IRA and other retirement plan accounts may be redeemed by telephone at 1-866-987-7888. Investors will be asked whether or not to withhold taxes from any distribution.

Retirement Plan Accounts. Purchases may also be made by SEP plans (Simplified Employee Benefit Plan), SIMPLE plans (Savings Incentive Match Plan for Employees of Small Employers), 401(k) plans, 403(b) plans, and other retirement plans. Forms of SEP, SIMPLE, and 403(b) plans are available from the Funds. The initial and subsequent investment minimums are not imposed on retirement plan accounts.

Because a retirement program involves commitments covering future years, it is important that the investment objectives of a Fund be consistent with the participant’s retirement objectives. Premature withdrawals from a retirement plan may result in adverse tax consequences. Please consult with your own tax or financial advisor.
