Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the 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'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.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 YEAR	3 YEARS	5 YEARS	10 YEARS
Institutional Class	$34	$127	$252	$615

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 111% of the average value of the portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of 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'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.

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's portfolio as of June 30, 2026 was 0.25 years. "Duration" is a measure of a debt security's price sensitivity to changes in interest rates. The longer the duration of the Fund'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's market price.

Principal Investment Risks

You should be aware that an investment in the Fund involves certain risks, including, among others, the following:

•

Market Risk As with any mutual fund, investment return and principal value will fluctuate, depending on general market conditions and other factors. 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. You may lose money if you invest in the Fund.

•

Active Management Risk The investment adviser's judgment about the attractiveness, value or potential appreciation of the Fund's investments may prove to be incorrect. The Fund could underperform other funds with similar objectives or investment strategies, if the Fund's overall investment selections or strategies fail to produce the intended results.

•

Interest Rate Risk Debt securities are subject to interest rate risk because the prices of debt securities tend to move in the opposite direction of interest rates. 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's investments. In general, debt securities with longer maturities are more sensitive to changes in interest rates.

•

Credit Risk The risk that the issuer or guarantor of a debt security is unable or unwilling, or perceived to be unable or unwilling, to pay interest or principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that security to fall. In general, lower-rated debt securities may have greater credit risk than investment grade securities.

•

Call Risk Certain debt securities may be called (redeemed) at the option of the issuer at a specified price before reaching their stated maturity date. 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's income.

•

Debt Securities Liquidity Risk Debt securities purchased by the Fund may be illiquid at the time of purchase or may be liquid at the time of purchase but subsequently become illiquid due to, among other things, events relating to the issuer of the securities (e.g., changes to the market's perception of the credit quality of the issuer), market events, economic

conditions, investor perceptions or lack of market participants. The Fund may be unable to sell illiquid securities on short notice or only at a price below current value.

•

Mortgage-Backed (and Other Asset-Backed) Securities Risk Mortgage-backed securities (and other asset-backed securities) are generally structured for the securities holders to receive periodic payments as the securities issuer receives payments of principal and/or interest on the mortgages (or loans) in an underlying asset pool. 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) the underlying asset pool may not pay as expected (which could mean sooner or later than expected), (ii) the securities issuer may have insufficient cash to make payment on the securities generally, or on certain tranches of securities and (iii) the credit support may be insufficient to make payment on the securities.

•

Government-Sponsored Enterprises Risk Obligations of U.S. Government agencies and authorities (such as Fannie Mae and Freddie Mac) are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. The Fund may purchase residential mortgage-backed securities and other asset-backed securities that are sponsored by U.S. Government agencies and authorities, and may purchase debt securities directly issued by U.S. Government agencies and authorities. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so. In addition, the value of obligations of U.S. Government agencies and authorities may be affected by changes in the credit rating of the U.S. Government.

•

Large Investor Risk Ownership of shares of the Fund may be concentrated in one or more large investors, including related persons of the investment adviser. These investors may redeem shares in substantial quantities or on a frequent basis, which may negatively impact the Fund's performance, may increase realized capital gains, may accelerate the realization of taxable income to other shareholders and may potentially limit the use of available capital loss carryforwards or certain other losses to offset any future realized capital gains. Large investor redemption activity also may increase the Fund's brokerage and other expenses.

•

Portfolio Turnover Risk The Fund maintains a very short average effective duration of one year or less. Given this mandate, the Fund routinely purchases and sells short-duration debt securities, resulting in a portfolio turnover rate that may be well in excess of 100%. Unlike equity funds or longer-duration bond funds, a high turnover rate for the Fund is expected and is a direct consequence of the Fund's investment strategy rather than a sign of speculative trading. A high portfolio turnover rate does, however, increase the Fund's transaction costs, including brokerage commissions, dealer mark-ups and other trading expenses, which are borne by the Fund and may reduce investment performance.

•

Failure to Meet Investment Objective There can be no assurance that the Fund will meet its investment objective.

Your investment in the Fund is not a bank deposit and is not insured nor guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other governmental agency.

Performance

The following chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year over the periods indicated and by showing how the Fund'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'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's past performance is not necessarily an indication of how the Fund will perform in the future both before and after taxes. Effective December 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 16, 2016, the Fund operated as a "government money market fund" as defined under Rule 2a-7 of the Investment Company Act of 1940, as amended (the "1940 Act"), and maintained a stable net asset value of $1.00 per share. The Fund's past performance in the bar chart and table for periods prior to December 16, 2016 reflect the Fund'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 us toll-free at 888-859-0698.

The year-to-date return for the Fund's Institutional Class for the six months ended June 30, 2026 was 1.56%.

⁽¹⁾ Returns prior to December 16, 2016 were achieved while the Fund was operated as a government money market fund.

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor'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).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a financial adviser), the Fund and/ or its investment adviser may pay the intermediary an administrative fee to compensate them for the services they provide (commonly referred to as administrative fee payments). These payments may create a conflict of interest by influencing the financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
