**Example—**This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at those periods. The Example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same, and that the contractual expense limitation agreement remains in place for the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**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 period, the Fund's portfolio turnover rate was 113.27% of the average value of its portfolio.

**Principal Investment Strategies**

To achieve its investment objective, the Fund invests at least 95% of its assets in U.S. Government and agency mortgage-backed securities ("MBS") and other securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities (including Ginnie Mae, Fannie Mae and Freddie Mac, as defined below), and collateralized mortgage obligations ("CMOs"), backed by U.S. Government and agency MBS. Some of the Fund's investments may be backed by the full faith and credit of the U.S. Government, while others may be supported only by the discretionary authority of the U.S. Government or only by the credit of the issuing agency or instrumentality.

Under normal market conditions, the target dollar-weighted average effective duration for the Fund is expected to range between one and three years. Duration is a measure of a fixed income security's price sensitivity to changes in interest rates. Duration takes into account a security's cash flows over time, including the possibility that a security might be prepaid by the issuer or redeemed by the holder prior to its stated maturity date. In contrast, maturity measures only the time until final payment is due. The duration of the Fund's portfolio is expressed in years and measures the portfolio's change in value for changes in interest rates. The Fund may also invest in U.S. Treasury bills. The securities held by the Fund may be fixed or variable rate obligations. The Fund may also purchase securities on a when-issued or delayed-delivery basis.

To construct the Fund's investment portfolio, the Fund's investment sub-adviser, M.D. Sass, LLC ("M.D. Sass" or "Sub-Adviser"), utilizes a process based on rigorous quantitative tests. These tests include projecting underlying mortgage prepayment rates under a variety of interest rate scenarios and demographic trends, with regard to any given security's sensitivity to cash flow risk. The nature of such testing is to measure homeowner refinancing/prepayment behavior, relative to mortgage rate changes, and other factors influencing such behavior. The Sub-Adviser's process is primarily structured to create value through intensive (i.e. bottom-up) security selection, portfolio construction and relative value trading. Top-down macro issues and factors are incorporated into the process when considered by the Sub-Adviser to be appropriate.

The Sub-Adviser may sell a security if its value becomes unattractive, such as when its fundamentals deteriorate, or when other investment opportunities exist that may have more attractive yields. The Fund may engage in frequent and active trading of securities as a part of its principal investment strategy.

**Principal Risks**

***As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund's net asset value and performance. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.***

**Market and Economic Risk:** Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities may decline in value due to factors affecting the securities markets generally, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The value of a security may also change in value due to factors that affect an individual issuer or a particular sector or industry. During a general downtown in the securities markets, multiple asset classes may decline in value simultaneously. When markets perform well, there can be no assurance that securities held by the Fund will participate in or otherwise benefit from the advance.

**Risks of U.S. Government Securities:** Securities issued by U.S. Government agencies and instrumentalities have different levels of U.S. Government credit support. Some are backed by the full faith and credit of the U.S. Government, while others are supported by only the discretionary authority of the U.S. Government or only by the credit of the agency or instrumentality. No assurance can be given that the U.S. Government will provide financial support to U.S. Government-sponsored instrumentalities because they are not obligated to do so by law. Guarantees of timely prepayment of principal and interest do not assure that the market prices and yields of the securities are guaranteed nor do they guarantee the net asset value or performance of the Fund, which will vary with changes in interest rates and other market conditions.

**Mortgage-Backed Securities Risks:**

**Prepayment Risk of Mortgage-Backed Securities**. In times of declining interest rates, the Fund's higher yielding securities are more likely to be prepaid and the Fund will have to replace them with securities having a lower yield.

**Extension Risk of Mortgage-Backed Securities**. In times of rising interest rates, mortgage prepayments will slow causing portfolio securities considered short or intermediate term to be long-term securities which fluctuate more widely in response to changes in interest rates than shorter term securities.

**Credit Risk:** Credit risk is the risk that the credit strength of an issuer will weaken and/or an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund's total return. Changes in an issuer's financial strength or in a security's credit rating may affect its value.

**Interest Rate Risk:** Interest rate risk is the risk that debt securities will decline in value because of changes in interest rates. As nominal interest rates rise, the value of certain debt securities held by the Fund is likely to decrease. Debt securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations.

Summary Prospectus \| Integrity Short Term Government Fund \| December 3, 2025<br> Page 2

------

**Income Risk:** Income risk is the risk that the income from the Fund's portfolio will decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the portfolio's current earnings rate.

**Variable Rate Securities Risk:** Variable rate securities pay interest at rates that reset periodically (typically, daily, monthly, quarterly, or semi-annually) in response to changes in the market rate of interest on which the interest rate is based. Variable rate securities generally are less price sensitive to interest rate changes than fixed rate debt securities. When interest rates fall, there may be a reduction in the payments of interest received by the Fund from its variable rate securities.

**When-Issued Securities Risk:** There is a risk that the price or yield obtained in a when-issued transaction may be less favorable than the price or yield available in the market when the security is delivered, or that failure of a party to a transaction to consummate the trade may result in a loss to the Fund or missed opportunity to obtain a price considered advantageous.

**Liquidity Risk:** Certain securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. These features may make it more difficult to sell or buy a security at a favorable price or time.

**Management Risk:** The ability of the Fund to meet its investment objective is directly related to the effectiveness of the sub-adviser's research, analysis and asset allocation among portfolio securities. If the sub-adviser's investment strategies do not produce the expected results, the value of your investment could be diminished or even lost entirely.

**Valuation Risk**: The sales price the Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

**Cybersecurity Risk**: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality. The Fund's share price may decline as a result of unauthorized actions taken during a security breach or subsequent market activity in response to the security breach.

**Fund Performance**

As a result of the reorganization of the M.D. Sass Short Term U.S. Government Agency Income Fund (the "Predecessor Fund") into Class I of the Fund on January 17, 2020 (the "Reorganization"), the performance and accounting history of the Predecessor Fund was assumed by Class I shares of the Fund. The performance information of Class I shares prior to completion of the Reorganization is that of the Predecessor Fund's Institutional Class shares.

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the performance of the Fund's Class I shares from calendar year to calendar year and by showing how the average annual total returns for 1, 5, and 10 years for Class I shares, and for 1 year and since inception periods for Class A shares, and how they compare with those of a broad measure of market performance and a supplemental index.

![](x25120214455600.gif)

During the periods shown in the bar chart, the highest return for a quarter was 3.31% (quarter ended December 31, 2023) and the lowest return for a quarter was -3.62% (quarter ended September 30, 2022). The year-to-date return of the Fund's Class I shares through September 30, 2025 is 7.40%.
