The example assumes that you invest $10,000 in the Fund for the periods indicated and then redeem in full at the end of each of the periods indicated.  The example also assumes that your investment has a 5% return each year and the Fund&#x2019;s operating expenses remain the same each year.  The example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only.&lt;/p&gt;

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 18% of the average value of the portfolio.&lt;/p&gt;

Under normal circumstances, the Fund will invest at least 25% of its total assets in equity securities, such as common stocks and a variety of securities convertible into common stock such as rights, warrants and convertible preferred stock.  Also, under normal circumstances, the Fund will invest at least 25% of its total assets in investment-grade debt securities, which may include: (1) U.S. Government securities (including securities issued by government-sponsored enterprises); (2) corporate debt securities; (3) structured products, such as agency and non-agency residential mortgage-backed securities, commercial mortgage-backed securities, other asset-backed securities (such as automobile loans, credit card receivables, other consumer loans and other debt securitizations), and collateralized obligations (such as collateralized debt obligations, collateralized loan obligations and collateralized mortgage obligations) (collectively, &#x201c;Structured Products&#x201d;); (4) loans and participation interests in loans or loan pools, such as bank loans, commercial loans, mortgage loans and consumer loans (collectively, &#x201c;Loans&#x201d;); and (5) securities issued by foreign governments, which may include sovereign debt.  We consider investment grade to mean rated at least BBB- by one or more nationally recognized credit ratings firms. The Fund may also invest up to 20% of its total assets in debt securities which are unrated or non-investment grade (commonly referred to as &#x201c;high yield&#x201d; or &#x201c;junk bonds&#x201d;); however, U.S. Government securities, as described above, even if unrated, do not count toward this 20% limit.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest in the equity securities of issuers of all sizes.  The Fund may invest in debt securities of all maturities.  The Fund may, but is not required to, use derivatives, such as options, futures and forward contracts, including interest rate futures, and options on futures.  The Fund may use derivatives for a variety of purposes, including to attempt to hedge against adverse changes in the market price of securities, interest rates; as a substitute for purchasing or selling securities; to attempt to increase the fund's return; to manage portfolio characteristics; and as a cash flow management technique.  These derivative instruments will count toward the Fund's &#x201c;at least 25%&#x201d; policy for investment grade debt securities only if the derivative instruments have economic characteristics similar to the securities included within that policy.  The Fund may invest in equity or debt securities issued by non-U.S. issuers, which securities may be denominated in U.S. dollars or foreign currencies.  As part of the Fund&#x2019;s strategy, the Fund may concentrate its investments in securities of relatively few issuers. &lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund&#x2019;s investment strategy for equity securities (which we call &#x201c;Quality at a Discount&#x201d;) is to buy above-average to highest-quality businesses, at prices that we believe are less than what the companies are worth.  We assess a company&#x2019;s quality based on its competitive position, return on invested capital, ability to redeploy capital, cash flow consistency, financial leverage and management team.  We compare the company&#x2019;s stock price to our estimate of business value, i.e., all the cash that the company will generate for its owners in the future.  For each company, we look at a range of business value estimates.  We then seek to buy stocks of companies that meet our quality criteria when they are priced at a discount to our estimates of business value.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We invest with a multiple-year time horizon.  We believe that purchasing stocks at prices less than our business value estimates provides opportunities for stock price appreciation, both as business values grow and as the market recognizes companies&#x2019; values.  Typically, we consider selling stocks as they approach or exceed our business value estimates.  We may also sell stocks for other reasons, including for the purchase of stocks that we believe offer better investment opportunities.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund&#x2019;s investment strategy with respect to debt securities is to select debt securities whose yield is sufficiently attractive in view of the risks of ownership.  We consider a number of factors such as the security&#x2019;s price, coupon and yield-to-maturity, as well as the credit quality of the issuer in deciding whether to invest in a particular debt security.  In addition, we review the terms of the debt security, including subordination, default, sinking fund and early redemption provisions.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;We do not try to &#x201c;time&#x201d; the market.  However, if there is cash available for investment and there are not securities that meet the Fund&#x2019;s investment criteria, the Fund may invest without limitation in high-quality cash and cash equivalents such as U.S. government securities or government money market fund shares.  If the Fund takes such a defensive position, it may be temporarily unable to achieve its investment objective.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, disinflation or deflation, general economic conditions, etc.). When interest rates rise, debt securities prices fall.  When interest rates fall, debt securities prices rise.  Changing interest rates (or the expectation of such changes) can be difficult to forecast and may have sudden and unpredictable effects in the markets and on the Fund&#x2019;s investments.  In general, debt securities with longer maturities are more sensitive to changes in interest rates.&lt;/span&gt;</oef:RiskTextBlock>

In general, lower-rated debt securities may have greater credit risk than investment grade securities.&lt;/span&gt;</oef:RiskTextBlock>

                                            due to the issuer&#x2019;s creditworthiness. The market prices of these securities may fluctuate

Call risk is the risk, especially during periods of falling interest rates, that an issuer will call or repay a debt security before its maturity date, likely causing the Fund to reinvest the proceeds at a lower interest rate, and thereby decreasing the Fund&#x2019;s income.&lt;/span&gt;</oef:RiskTextBlock>

Risks from Structured Products include (i) underlying collateral may not be adequate to make payments to investors, (ii) underlying collateral may default, decline in value or quality or be downgraded by a rating agency; (iii) the structure and complexity of the transaction and the legal documents could lead to disputes among investors and (iv) the Structured Product&#x2019;s manager may perform poorly.  Non-payment on a Structured Product would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the Fund&#x2019;s net asset value per share.  In most cases, structured products are issued in several classes (sometimes called tranches), with different payment priorities.  Generally, the lower classes are subordinated in priority of payments, and will be impacted first in case of an issuer&#x2019;s non-payment of scheduled interest or principal.  In some cases, the securities holders of one class must receive payment in full before the securities holders of a lower class receive any payments.  The Fund may invest in any class of a Structured Product offering.  Some Structured Products have credit ratings (or in some cases only certain classes of a Structured Product have credit ratings), but in many cases Structured Products do not have credit ratings.  Normally, Structured Products are privately offered and sold (that is, they are not registered under the securities laws), which means (A) the security will not be traded on an exchange, (B) less information about the security may be available as compared to publicly offered securities, (C) only certain institutions may buy and sell the security, and (D) the security may have greater liquidity risk.  There can be no assurance that a market will exist or will be active enough for the Fund to sell any Structured Product.&lt;/span&gt;</oef:RiskTextBlock>

                                            to credit risk, including the risk of non-payment of scheduled interest or principal. Such
                                            non-payment would result in a reduction of income to the Fund, a reduction in the value of
                                            the investment and a potential decrease in the Fund&#x2019;s net asset value per share. Also,
                                            increases in interest rates may lead to an increase in loan defaults. In the event of a loan
                                            borrower&#x2019;s non-payment of scheduled interest or principal, there can be no assurance
                                            that any collateral securing a Loan could be readily liquidated, or that liquidation proceeds
                                            would satisfy the Loan borrower&#x2019;s obligations. In the event of bankruptcy of a Loan
                                            borrower, the Fund could experience delays or limitations with respect to its ability to
                                            realize the benefits of the collateral securing the Loan. Loans in which the Fund may invest
                                            may not be rated by a rating agency, may not be registered with the SEC or any state securities
                                            commission, and will not be listed on any national securities exchange. The amount of public
                                            information available with respect to Loans will generally be less extensive than that available

The use of derivatives may carry more risk than other types of investments.  Derivatives are subject to a number of risks including leverage, counterparty, liquidity, interest rate, market, credit, operational, management and legal risks, and the risk of improper valuation.  Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and in some cases the Fund could lose more than the principal amount invested.  Derivative strategies may also involve leverage, which may further exaggerate a loss.&lt;/span&gt;</oef:RiskTextBlock>

Total returns shown include fee waivers and expense reimbursements, if any; total returns would have been lower had there been no waivers and/or reimbursements.

Actual after-tax returns depend on an investor&#x2019;s tax situation and may differ from those shown.  In some instances, the return after taxes may be greater than the return before taxes because you are assumed to be able to use the capital loss on the sale of Fund shares to offset other taxable gains.  After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement account (IRA).&lt;/p&gt;

The example also assumes that your investment has a 5% return each year and the Fund&#x2019;s operating expenses remain the same each year.  The example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only.&lt;/p&gt;

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 16% of the average value of the portfolio.&lt;/p&gt;

its net assets, plus the amount of any borrowings for investment purposes, in debt securities and related derivative instruments. These
debt securities may include: (1) U.S. Government securities (including securities issued by government-sponsored enterprises); (2) structured
products, such as agency and non-agency residential mortgage-backed securities, commercial mortgage-backed securities, other asset-backed
securities (such as automobile loans, credit card receivables, other consumer loans and other debt securitizations), and collateralized
obligations (such as collateralized debt obligations, collateralized loan obligations and collateralized mortgage obligations) (collectively,
&#x201c;Structured Products&#x201d;); (3) corporate debt securities; (4) loans and participation interests in loans or loan pools, such
as bank loans, commercial loans, mortgage loans and consumer loans (collectively, &#x201c;Loans&#x201d;); and (5) securities issued by
foreign governments, which may include sovereign debt.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest up to 25% of its total assets in debt securities which are unrated or which are non-investment grade (commonly referred to as &#x201c;high yield&#x201d; or &#x201c;junk bonds&#x201d;); however, U.S. Government securities, as described above, even if unrated, do not count toward this 25% limit.  We consider investment grade to mean rated at least BBB- by one or more nationally recognized credit ratings firm. &lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may, but is not required to, use derivatives, such as options, futures and forward contracts, including bond and interest rate futures and options on futures.  The Fund may use derivatives for a variety of purposes, including to attempt to hedge against adverse changes in the market price of securities, interest rates; as a substitute for purchasing or selling securities; to attempt to increase the fund's return; to manage portfolio characteristics; and as a cash flow management technique.  The Fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. These derivative instruments will count toward the Fund&#x2019;s 80% policy only if they have economic characteristics similar to the securities included within that policy.  &lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest in securities issued by non-U.S. issuers, which securities may be denominated in U.S. dollars or foreign currencies.  We select debt securities whose yield is sufficiently attractive in view of the risks of ownership.  In deciding whether the Fund should invest in particular debt securities, we consider a number of factors such as the price, coupon and yield-to-maturity, as well as the credit quality of the issuer.  We review the terms of the debt security, including subordination, default, sinking fund, and early redemption provisions.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest in debt securities of all maturities, but expects
to maintain a dollar-weighted average maturity of less than ten years. The dollar-weighted average maturity of the Fund&#x2019;s portfolio
as of June&#160;30, 2026 was 8.1 years.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may also invest in common stocks, preferred stocks and securities convertible into stocks.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;If we determine that circumstances warrant, a greater portion of the Fund&#x2019;s portfolio may be retained in cash and cash equivalents such as U.S. Government securities or other high-quality debt securities.  In the event that the Fund takes such a temporary defensive position, it may not be able to achieve its investment objective during this temporary period.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, disinflation or deflation, general economic conditions, etc.). When interest rates rise, debt securities prices fall.  When interest rates fall, debt securities prices rise.  Changing interest rates (or the expectation of such changes) can be difficult to forecast and may have sudden and unpredictable effects in the markets and on the Fund&#x2019;s investments.  In general, debt securities with longer maturities are more sensitive to changes in interest rates.&lt;/span&gt;</oef:RiskTextBlock>

Risks from Structured Products include (i) underlying collateral may not be adequate to make payments to investors, (ii) underlying collateral may default, decline in value or quality or be downgraded by a rating agency; (iii) the structure and complexity of the transaction and the legal documents could lead to disputes among investors and (iv) the Structured Product&#x2019;s manager may perform poorly.  Non-payment on a Structured Product would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the Fund&#x2019;s net asset value per share.  In most cases, structured products are issued in several classes (sometimes called tranches), with different payment priorities.  Generally, the lower classes are subordinated in priority of payments, and will be impacted first in case of an issuer&#x2019;s non-payment of scheduled interest or principal.  In some cases, the securities holders of one class must receive payment in full before the securities holders of a lower class receive any payments.  The Fund may invest in any class of a Structured Product offering.  Some Structured Products have credit ratings (or in some cases only certain classes of a Structured Product have credit ratings), but in many cases Structured Products do not have credit ratings.  Normally, Structured Products are privately offered and sold (that is, they are not registered under the securities laws), which means (A) the security will not be traded on an exchange, (B) less information about the security may be available as compared to publicly offered securities, (C) only certain institutions may buy and sell the security, and (D) the security may have greater liquidity risk.  There can be no assurance that a market will exist or will be active enough for the Fund to sell any Structured Product.&lt;/span&gt;</oef:RiskTextBlock>

                                            to credit risk, including the risk of non-payment of scheduled interest or principal. Such
                                            non-payment would result in a reduction of income to the Fund, a reduction in the value of

                                            increases in interest rates may lead to an increase in loan defaults. In the event of a loan
                                            borrower&#x2019;s non-payment of scheduled interest or principal, there can be no assurance
                                            that any collateral securing a Loan could be readily &lt;span&gt;liquidated, or that liquidation proceeds
                                            would satisfy the Loan borrower&#x2019;s obligations. In the event of bankruptcy of a Loan
                                            borrower, the Fund could experience delays or limitations with respect to its ability to

The use of derivatives may carry more risk than other types of investments.  Derivatives are subject to a number of risks including leverage, counterparty, liquidity, interest rate, market, credit, operational, management and legal risks, and the risk of improper valuation.  Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and in some cases the Fund could lose more than the principal amount invested.  Derivative strategies may also involve leverage, which may further exaggerate a loss.&lt;/span&gt;</oef:RiskTextBlock>

in the Fund by showing the Fund&#x2019;s performance over the periods indicated and by showing how the Fund&#x2019;s average annual total
returns for the periods indicated, both before and after taxes, compared to those of a relevant broad-based securities market index.
The Bloomberg U.S. Aggregate Bond Index, the Fund&#x2019;s primary comparative index, is generally representative of the market for investment
grade, U.S. dollar-denominated, fixed-rate taxable bonds. All Fund performance numbers are calculated after deducting fees and expenses,
and all numbers assume reinvestment of dividends. Total returns shown include fee waivers and expense reimbursements, if any; total returns
would have been lower had there been no waivers and/or reimbursements. The Fund&#x2019;s past performance is not necessarily an indication
of how the Fund will perform in the future both before and after taxes. Updated performance information is available at weitzinvestments.com

The example also assumes that your investment has a 5% return each year and the Fund&#x2019;s operating expenses remain the same each year.  The example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only.&lt;/p&gt;

      id="Fact000279">Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and
sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 10% of the average value of the portfolio.</oef:PortfolioTurnoverHeading>

at a Discount&#x201d;) is to buy above-average to highest-quality businesses, at prices that we believe are less than what the companies
are worth. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment
purposes, in equity securities of large-cap companies and related derivative instruments. The Fund considers large-cap companies to be
those with market capitalizations that would be included in the Bloomberg 1000 Index. As of May 29, 2026, the market capitalization range
for the Bloomberg 1000 Index was approximately $222 million to $5,109 billion. The Fund may invest in securities issued by non-U.S. companies,
which may be denominated in U.S. dollars or foreign currencies. As part of the Fund&#x2019;s strategy, the Fund may concentrate its investments
in securities of relatively few issuers.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We assess a company&#x2019;s quality based on its competitive position, return on invested capital, ability to redeploy capital, cash flow consistency, financial leverage and management team.  We compare the company&#x2019;s stock price to our estimate of business value, i.e., all the cash that the company will generate for its owners in the future.  For each company, we look at a range of business value estimates.  We then seek to buy stocks of companies that meet our quality criteria when they are priced at a discount to our estimates of business value.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We invest with a multiple-year time horizon.  We believe that purchasing stocks at prices less than our business value estimates provides opportunities for stock price appreciation, both as business values grow and as the market recognizes companies&#x2019; values.  Typically, we consider selling stocks as they approach or exceed our business value estimates.  We may also sell stocks for other reasons, including for the purchase of stocks that we believe offer better investment opportunities.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;We do not try to &#x201c;time&#x201d; the market.  However, if there is cash available for investment and there are not securities that meet the Fund&#x2019;s investment criteria, the Fund may invest without limitation in high-quality cash and cash equivalents such as U.S. government securities or government money market fund shares.  If the Fund takes such a defensive position, it may be temporarily unable to achieve its investment objective.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

average annual total returns for the periods indicated, both before and after taxes, compared to those of a relevant broad-based securities
market index. The Bloomberg 1000 Index, the Fund&#x2019;s primary comparative index, reflects the performance of the 1,000 largest publicly

of dividends. Total returns shown include fee waivers and expense reimbursements, if any; total returns would have been lower had there
been no waivers and/or reimbursements. The Fund&#x2019;s past performance is not necessarily an indication of how the Fund will perform
in the future both before and after taxes. Updated performance information is available at weitzinvestments.com or by calling us toll-free

The example assumes that you invest $10,000 in the Fund for the periods indicated and then redeem in full at the end of each of the periods indicated.  The example also assumes that your investment has a 5% return each year and the Fund&#x2019;s operating expenses remain the same each year.  The example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only.&lt;/p&gt;

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 11% of the average value of the portfolio.&lt;/p&gt;

at a Discount&#x201d;) is to buy above-average to highest-quality businesses, at prices that we believe are less than what the companies
are worth. The Fund is a &#x201c;multi-cap&#x201d; fund and may invest in securities of any market capitalization. Under normal circumstances,
the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities
of companies with market capitalizations that would be included in the Bloomberg 3000 Index and related derivative instruments. As of
May 29, 2026, the market capitalization range for the Bloomberg 3000 Index was approximately $8 million to $5,109 billion. The Fund may
invest in securities issued by non-U.S. companies, which may be denominated in U.S. dollars or foreign currencies. As part of the Fund&#x2019;s
strategy, the Fund may concentrate its investments in securities of relatively few issuers.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We assess a company&#x2019;s quality based on its competitive position, return on invested capital, ability to redeploy capital, cash flow consistency, financial leverage and management team.  We compare the company&#x2019;s stock price to our estimate of business value, i.e., all the cash that the company will generate for its owners in the future.  For each company, we look at a range of business value estimates.  We then seek to buy stocks of companies that meet our quality criteria when they are priced at a discount to our estimates of business value.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We invest with a multiple-year time horizon.  We believe that purchasing stocks at prices less than our business value estimates provides opportunities for stock price appreciation, both as business values grow and as the market recognizes companies&#x2019; values.  Typically, we consider selling stocks as they approach or exceed our business value estimates.  We may also sell stocks for other reasons, including for the purchase of stocks that we believe offer better investment opportunities.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;We do not try to &#x201c;time&#x201d; the market.  However, if there is cash available for investment and there are not securities that meet the Fund&#x2019;s investment criteria, the Fund may invest without limitation in high-quality cash and cash equivalents such as U.S. government securities or government money market fund shares.  If the Fund takes such a defensive position, it may be temporarily unable to achieve its investment objective.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 18% of the average value of the portfolio.&lt;/p&gt;

The Fund is a &#x201c;multi-cap&#x201d; fund and may invest in securities of any market capitalization.  The Fund may invest in securities issued by non-U.S. companies, which may be denominated in U.S. dollars or foreign currencies.  As part of the Fund&#x2019;s strategy, the Fund may concentrate its investments in securities of relatively few issuers and is considered to be a &#x201c;non-diversified&#x201d; fund.  The Fund invests in long positions in stocks and other securities, when we anticipate that the value of such securities will increase.  The Fund also invests in short positions in stocks and other securities, including short sales of exchange traded funds (&#x201c;ETFs&#x201d;), when we anticipate a decline in the value of such securities.  The Fund has the ability to borrow money to invest in its long positions, and may buy and sell futures contracts, such as stock index futures contracts.  The Fund&#x2019;s mix of long positions and short positions will change over time based on the investment adviser&#x2019;s assessment of market conditions.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We assess a company&#x2019;s quality based on its competitive position, return on invested capital, ability to redeploy capital, cash flow consistency, financial leverage and management team.  We compare the company&#x2019;s stock price to our estimate of business value, i.e., all the cash that the company will generate for its owners in the future.  For each company, we look at a range of business value estimates.  We then seek to buy stocks of companies that meet our quality criteria when they are priced at a discount to our estimates of business value.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We invest with a multiple-year time horizon.  We believe that purchasing stocks at prices less than our business value estimates provides opportunities for stock price appreciation, both as business values grow and as the market recognizes companies&#x2019; values.  Typically, we consider selling stocks as they approach or exceed our business value estimates.  We may also sell stocks for other reasons, including for the purchase of stocks that we believe offer better investment opportunities.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;We do not try to &#x201c;time&#x201d; the market.  However, if there is cash available for investment and there are not securities that meet the Fund&#x2019;s investment criteria, the Fund may invest without limitation in high-quality cash and cash equivalents such as U.S. government securities or government money market fund shares.  If the Fund takes such a defensive position, it may be temporarily unable to achieve its investment objective.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;The Fund&#x2019;s investment strategies for short positions can include (1)&#160;selling short an ETF or other security that tracks a broad or narrow market index, in hopes of buying the security at a future date at a lower price, (2)&#160;simultaneously buying a put option and selling a call option on an ETF or other security that tracks a broad or narrow market index, (3)&#160;buying an ETF or other security that is designed to appreciate in value when the value of a broad or narrow market index declines, (4)&#160;simultaneously holding a short position in one security and a long position in another security, with the objective of earning positive returns on the combined set of positions, (5)&#160;selling a covered call option on a security that the Fund owns for the duration of the option period and (6)&#160;holding a short position in an ETF or other security that tracks a broad or narrow market index and adding to the Fund&#x2019;s long positions in particular stocks by a corresponding amount.&lt;/p&gt;

                                            sales&#x201d;), which is a speculative technique. The Fund will suffer a loss when the price
                                            of a security that it has sold short increases; the loss of value on a short position is
                                            theoretically unlimited. Also there may be times when the Fund&#x2019;s lender demands, or
                                            market conditions dictate, that the borrowed securities be returned to the lender on short
                                            notice, and the Fund may have to borrow the securities from another lender or purchase the
                                            securities at an unfavorable price. In addition, there is a risk that the third party to
                                            a short sale will not fulfill its contractual obligations, which could cause a loss to the
                                            Fund. The use of short sales will increase the Fund&#x2019;s expenses. And because the Fund
                                            invests in both long and short equity positions, the Fund has overall exposure to changes
                                            in the value of securities, which could exceed the value of the Fund&#x2019;s assets. This
                                            may magnify gains and losses and increase the volatility of the Fund&#x2019;s returns.&lt;/span&gt;</oef:RiskTextBlock>

                                            with any such borrowing. If the interest and other expenses on borrowings is greater than

                                            decrease the overall return to the Fund&#x2019;s shareholders. The use of leverage will also
                                            tend to magnify the volatility of the Fund&#x2019;s returns and may increase the Fund's sensitivity

The use of derivatives may carry more risk than other types of investments.  Derivatives are subject to a number of risks including leverage, counterparty, liquidity, interest rate, market, credit, operational, management and legal risks, and the risk of improper valuation.  Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and in some cases the Fund could lose more than the principal amount invested. Derivative strategies may also involve leverage, which may further exaggerate a loss.&lt;/span&gt;</oef:RiskTextBlock>

of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year over the periods indicated and by showing
how the Fund&#x2019;s average annual total returns for the periods indicated, both before and after taxes, compared to those of a relevant
broad-based securities market index. The Bloomberg 3000 Index, the Fund&#x2019;s primary comparative index, reflects the performance of
the broad U.S. stock market and consists of companies of all market capitalizations. All Fund performance numbers are calculated after
deducting fees and expenses, and all numbers assume reinvestment of dividends. Total returns shown include fee waivers and expense reimbursements,
if any; total returns would have been lower had there been no waivers and/or reimbursements. The Fund&#x2019;s past performance is not
necessarily an indication of how the Fund will perform in the future both before and after taxes. Updated performance information is

The example assumes that you invest $10,000 in the Fund for the periods indicated and then redeem in full at the end of each of the periods indicated.  The example also assumes that your investment has a 5% return each year and the Fund&#x2019;s operating expenses remain the same each year.  The example reflects the contractual fee waiver and/or expense reimbursement arrangement, if applicable, for the current duration of the arrangement only.&lt;/p&gt;

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating
expenses or in the example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover
rate was 41% of the average value of the portfolio.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;These debt securities may include: (1) U.S. Government securities (including securities issued by government-sponsored enterprises); (2) structured products, such as agency and non-agency residential mortgage-backed securities, commercial mortgage-backed securities, other asset-backed securities (such as automobile loans, credit card receivables, other consumer loans and other debt securitizations), and collateralized obligations (such as collateralized debt obligations, collateralized loan obligations and collateralized mortgage obligations) (collectively, &#x201c;Structured Products&#x201d;); (3) corporate debt securities; (4) loans and participation interests in loans or loan pools, such as bank loans, commercial loans, mortgage loans and consumer loans (collectively, &#x201c;Loans&#x201d;); and (5) securities issued by foreign governments, which may include sovereign debt.  The Fund may invest up to 15% of its total assets in debt securities which are unrated or non-investment grade (commonly referred to as &#x201c;high yield&#x201d; or &#x201c;junk bonds&#x201d;); however, U.S. Government securities, as described above, even if unrated, do not count toward this 15% limit.  We consider investment grade to mean rated at least BBB- by one or more nationally recognized credit ratings firms. &lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may, but is not required to, use derivatives, such as options, futures contracts, including bond and interest rate futures, and options on futures.  The Fund may use derivatives for a variety of purposes, including to attempt to hedge against adverse changes in the market price of securities, interest rates; as a substitute for purchasing or selling securities; to attempt to increase the fund's return; to manage portfolio characteristics; and as a cash flow management technique.  These derivative instruments will count toward the Fund's 80% policy only if they have economic characteristics similar to the securities included within that policy.  &lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest in securities issued by non-U.S. issuers, which securities may be denominated in U.S. dollars or foreign currencies.  We select debt securities whose yield is sufficiently attractive in view of the risks of ownership.  In deciding whether the Fund should invest in particular debt securities, we consider a number of factors such as the price, coupon and yield-to-maturity, as well as the credit quality of the issuer.  We review the terms of the debt security, including subordination, default, sinking fund, and early redemption provisions.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may invest in debt securities of all maturities, but expects
to maintain an average effective duration between one to three and a half years. The average effective duration of the Fund&#x2019;s portfolio
as of June&#160;30, 2026 was 2.01 years. &#x201c;Duration&#x201d; is a measure of a debt security&#x2019;s price sensitivity to changes
in interest rates. The longer the duration of the Fund&#x2019;s overall portfolio (or an individual debt security), the more sensitive
its market price will be to changes in interest rates. For example, if interest rates increase by 1%, the market price of a debt security
with a duration of 3 years will generally decrease by approximately 3%. Conversely, a 1% decline in interest rates will generally result
in an increase of approximately 3% of that security&#x2019;s market price.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0 0 10pt"&gt;The Fund may also invest in common stocks, preferred stocks and securities convertible into stocks.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;If we determine that circumstances warrant, a greater portion of the Fund&#x2019;s portfolio may be retained in cash and cash equivalents such as U.S. Government securities or other high-quality debt securities.  In the event that the Fund takes such a temporary defensive position, it may not be able to achieve its investment objective during this temporary period.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, disinflation or deflation, general economic conditions, etc.). When interest rates rise, debt securities prices fall.  When interest rates fall, debt securities prices rise.  Changing interest rates (or the expectation of such changes) can be difficult to forecast and may have sudden and unpredictable effects in the markets and on the Fund&#x2019;s investments.  In general, debt securities with longer maturities are more sensitive to changes in interest rates.&lt;/span&gt;</oef:RiskTextBlock>

Risks from Structured Products include (i) underlying collateral may not be adequate to make payments to investors, (ii) underlying collateral may default, decline in value or quality or be downgraded by a rating agency; (iii) the structure and complexity of the transaction and the legal documents could lead to disputes among investors and (iv) the Structured Product&#x2019;s manager may perform poorly.  Non-payment on a Structured Product would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the Fund&#x2019;s net asset value per share.  In most cases, structured products are issued in several classes (sometimes called tranches), with different payment priorities.  Generally, the lower classes are subordinated in priority of payments, and will be impacted first in case of an issuer&#x2019;s non-payment of scheduled interest or principal.  In some cases, the securities holders of one class must receive payment in full before the securities holders of a lower class receive any payments.  The Fund may invest in any class of a Structured Product offering.  Some Structured Products have credit ratings (or in some cases only certain classes of a Structured Product have credit ratings), but in many cases Structured Products do not have credit ratings.  Normally, Structured Products are privately offered and sold (that is, they are not registered under the securities laws), which means (A) the security will not be traded on an exchange, (B) less information about the security may be available as compared to publicly offered securities, (C) only certain institutions may buy and sell the security, and (D) the security may have greater liquidity risk.  There can be no assurance that a market will exist or will be active enough for the Fund to sell any Structured Product.&lt;/span&gt;</oef:RiskTextBlock>

                                            to credit risk, including the risk of non-payment of scheduled interest or principal. Such
                                            non-payment would result in a reduction of income to the Fund, a reduction in the value of
                                            the investment and a potential decrease in the Fund&#x2019;s net asset value per share. Also,
                                            increases in interest rates may lead to an increase in loan defaults. In the event of a loan
                                            borrower&#x2019;s non-payment of scheduled interest or principal, there can be no assurance
                                            that any collateral securing a Loan could be readily liquidated, or that liquidation proceeds
                                            would satisfy the Loan borrower&#x2019;s obligations. In the event of bankruptcy of a Loan
                                            borrower, the Fund could experience delays or limitations with respect to its ability to
                                            realize the benefits of the collateral securing the Loan. Loans in which the Fund may invest
                                            may not be rated by a rating agency, may not be registered with the SEC or any state securities
                                            commission, and will not be listed on any national securities exchange. The amount of public
                                            information available with respect to Loans will generally be less extensive than that available

                                            Risk&lt;/i&gt;&lt;/b&gt; Derivatives are instruments, such as options, futures and forward contracts,
                                            whose value is derived from that of other assets, rates or indices. The use of derivatives
                                            may carry more risk than other types of investments. Derivatives are subject to a number
                                            of risks including leverage, counterparty, liquidity, interest rate, market, credit, operational,
                                            management and legal risks, and the risk of improper valuation. Changes in the value of a
                                            derivative may not correlate perfectly with the underlying asset, rate or index, and in some
                                            cases the Fund could lose more than the principal amount invested. Derivative strategies
                                            may also involve leverage, which may further exaggerate a loss.&lt;/span&gt;</oef:RiskTextBlock>

The Bloomberg US Aggregate Bond Index, the Fund&#x2019;s primary comparative index, is a broad-based securities market index generally representative of the market for investment grade, U.S. dollar-denominated, fixed-rate taxable bonds.   All Fund performance numbers are calculated after deducting fees and expenses, and all numbers assume reinvestment of dividends.  Total returns shown include fee waivers and expense reimbursements, if any; total returns would have been lower had there been no waivers and/or reimbursements.  The Fund&#x2019;s past performance is not necessarily an indication of how the Fund will perform in the future both before and after taxes.  Effective December&#160;16, 2016, the Fund revised its principal investment strategies.  The Fund&#x2019;s past performance in the bar chart and table for periods prior to December&#160;16, 2016 reflect the Fund&#x2019;s prior principal investment strategies and may not be indicative of future performance results.

sells securities (or &#x201c;turns over&#x201d; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs
and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating

its net assets, plus the amount of any borrowings for investment purposes, in debt obligations issued or guaranteed by the U.S. Government,
its agencies and instrumentalities and repurchase agreements on such securities, and related derivative instruments. The balance of the
Fund&#x2019;s assets may be invested in U.S. dollar-denominated investment grade debt securities, including corporate debt securities,
mortgage-backed securities and asset backed securities. We consider investment grade to mean rated at least BBB- by one or more nationally
recognized credit ratings firms. The Fund may invest in securities that are unrated if we determine that such securities are of investment
grade quality. The Fund may also invest in government money market funds or exchange traded funds which invest substantially all of their
assets in U.S. government securities.&lt;/p&gt;

&lt;p style="font: 9pt/115% Arial Nova,sans-serif; margin: 0"&gt;The Fund may invest in debt securities of all maturities, but expects to
limit its average effective duration to one year or less. The average effective duration of the Fund&#x2019;s portfolio as of June&#160;30,
2026 was 0.25 years. &#x201c;Duration&#x201d; is a measure of a debt security&#x2019;s price sensitivity to changes in interest rates. The
longer the duration of the Fund&#x2019;s overall portfolio (or an individual debt security), the more sensitive its market price will
be to changes in interest rates. For example, if interest rates increase by 1%, the market price of a debt security with a duration of
1 year will generally decrease by approximately 1%. Conversely, a 1% decline in interest rates will generally result in an increase of
approximately 1% of that security&#x2019;s market price.&lt;/p&gt;

Market risk includes political, regulatory, economic, social and health risks (including the risks presented by the spread of infectious diseases) which can lead to increased market volatility and negative impacts on local and global financial markets, and the duration and severity of the impact of these risks on markets cannot be reasonably estimated.  &lt;b&gt;You may lose money if you invest in the Fund.&lt;/b&gt;&lt;/span&gt;</oef:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, disinflation or deflation, general economic conditions, etc.). When interest rates rise, debt securities prices fall.  When interest rates fall, debt securities prices rise.  Changing interest rates (or the expectation of such changes) can be difficult to forecast and may have sudden and unpredictable effects in the markets and on the Fund&#x2019;s investments.  In general, debt securities with longer maturities are more sensitive to changes in interest rates.&lt;/span&gt;</oef:RiskTextBlock>

Call risk is the risk, especially during periods of falling interest rates, that an issuer will call or repay a debt security before its maturity date, likely causing the Fund to reinvest the proceeds at a lower interest rate, and thereby decreasing the Fund&#x2019;s income.&lt;/span&gt;</oef:RiskTextBlock>

Sometimes these securities are issued in separate tranches, which can mean the securities holders of one tranche receive payment in full before the securities holders of another tranche receive payments.  Credit support may be provided for these securities, which can mean the securities issuer, an affiliated party or a third party provides additional assets, or makes additional promises, with respect to payment to the securities holders.  Risks to the securities holders can include (i)&#160;the underlying asset pool may not pay as expected (which could mean sooner or later than expected), (ii)&#160;the securities issuer may have insufficient cash to make payment on the securities generally, or on certain tranches of securities and (iii)&#160;the credit support may be insufficient to make payment on the securities.&lt;/span&gt;</oef:RiskTextBlock>

The following chart and table provide an indication of the risks
of investing in the Fund by showing changes in the Fund&#x2019;s performance from year to year over the periods indicated and by showing
how the Fund&#x2019;s average annual total returns for the periods indicated, both before and after taxes, compared to those of the relevant
securities market index. The Bloomberg US Aggregate Bond Index, the Fund&#x2019;s primary comparative index, is a broad-based securities
market index generally representative of the market for investment grade, U.S. dollar-denominated, fixed-rate taxable bonds. All Fund
performance numbers are calculated after deducting fees and expenses, and all numbers assume reinvestment of dividends. Total returns
shown include fee waivers and expense reimbursements, if any; total returns would have been lower had there been no waivers and/or reimbursements.
The Fund&#x2019;s past performance is not necessarily an indication of how the Fund will perform in the future both before and after taxes.
Effective December&#160;16, 2016, the Fund revised its principal investment strategies and policies to permit the Fund to invest in a
diversified portfolio of short-term debt securities and to have a fluctuating net asset value. Prior to December&#160;16, 2016, the Fund
operated as a &#x201c;government money market fund&#x201d; as defined under Rule 2a-7 of the Investment Company Act of 1940, as amended
(the &#x201c;1940 Act&#x201d;), and maintained a stable net asset value of $1.00 per share. The Fund&#x2019;s past performance in the bar
chart and table for periods prior to December&#160;16, 2016 reflect the Fund&#x2019;s prior principal investment strategies and policies
and may not be indicative of future performance results. Updated performance information is available at weitzinvestments.com or by calling

For performance prior to that date, this table includes the actual performance of the Fund&#x2019;s Investor Class (and uses the actual expenses of the Fund&#x2019;s Investor Class, for such period of time), without any adjustments.  For any such period of time, the performance of the Fund&#x2019;s Institutional Class would have been substantially similar to, and higher than, the performance of the Fund&#x2019;s Investor Class, because the shares of both classes are invested in the same portfolio of securities, but Institutional Class shares would have had lower expenses.</link:footnote>
