The Fund invests primarily in shares of other registered investment companies (the “underlying funds”). The Fund will be diversified among a number of asset classes and its allocation among underlying funds will be based on an asset allocation model developed by Madison Asset Management, LLC (“Madison”), the Fund’s investment adviser. Under normal circumstances, the Fund’s total net assets will be allocated among various asset classes and underlying funds, including those whose shares trade on a stock exchange (exchange traded funds or “ETFs”), with target allocations over time of approximately 60% equity investments and 40% fixed income investments. Underlying funds in which the Fund invests may include funds advised by Madison and/or its affiliates, including other Madison Funds (the “affiliated underlying funds”). Generally, Madison will not invest more than 75% of the Fund’s net assets, at the time of purchase, in affiliated underlying funds. Although actual allocations may vary, as of October 31, 2025, the Fund’s portfolio allocation as a percentage of net assets was: 

With regard to investments in debt securities, Madison’s bias is toward securities with intermediate and short-term maturities. As of December 31, 2025, the weighted average duration of the Fund’s debt portfolio was 5.63 years.

Madison may employ multiple analytical approaches to determine the appropriate asset allocation for the Fund, including: 

In addition, Madison has a flexible mandate that permits the Fund, at the sole discretion of Madison, to materially reduce equity risk exposures when and if conditions are deemed to warrant such an action.

The Fund’s investment strategy reflects Madison’s general “Participate and Protect^®” investment philosophy. Madison’s expectation is that investors in the Fund will participate in market appreciation during bull markets and experience something less than full participation during bear markets compared with investors in portfolios holding more speculative and volatile securities; therefore, this investment philosophy is intended to represent a conservative investment strategy. There is no assurance that Madison’s expectations regarding this investment strategy will be realized.

Although the Fund expects to pursue its investment objective utilizing its principal investment strategies regardless of market conditions, the Fund may invest up to 100% in cash, money market funds, and/or money market instruments. To the extent the Fund engages in this temporary defensive position, the Fund’s ability to achieve its investment objective may be diminished.

Although the Fund expects to pursue its investment objective utilizing its principal investment strategies regardless of market conditions, the Fund may invest up to 100% in cash, money market funds, and/or money market instruments. To the extent the Fund engages in this temporary defensive position, the Fund’s ability to achieve its investment objective may be diminished.

The Fund seeks to achieve its investment objective through diversified investments in a broad range of corporate debt securities, obligations of the U.S. Government and its agencies, and money market instruments. In seeking to achieve the Fund’s goals, the Fund’s investment adviser, Madison Asset Management, LLC ("Madison"), will (1) shorten or lengthen the weighted average life of the Fund based on its anticipation of the movement of interest rates (the dollar weighted average maturity is expected to be ten years or less), and (2) monitor the yields of the various bonds that satisfy the Fund’s investment guidelines to determine the best combination of yield, credit risk and diversification for the Fund. Under normal market conditions, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in higher quality bond issues and, therefore, intends to maintain an overall portfolio quality rating of A by Standard & Poor’s and/or A2 by Moody’s. The dollar weighted average maturity of the Fund as of December 31, 2025 was 3.63 years. The Fund generally holds 50-75 individual securities in its portfolio at any given time. This reflects Madison's belief that your money should be invested in Madison’s top investment ideas, and that focusing on Madison's highest conviction investment ideas is the best way to achieve the Fund’s investment objective.

Madison may alter the composition of the Fund with regard to quality and maturity and may sell securities prior to maturity. Under normal circumstances, however, turnover for the Fund is generally not expected to exceed 100%. Sales of Fund securities may result in capital gains. This can occur any time Madison sells a bond at a price that was higher than the purchase price, even if Madison does not engage in active or frequent trading. Madison’s intent when it sells bonds is to “lock in” any gains already achieved by that investment or, alternatively, prevent additional or potential losses that could occur if Madison continued to hold the bond. Turnover may also occur when Madison finds an investment that could generate a higher return than the investment currently held. However, increasing portfolio turnover at a time when Madison’s assessment of market performance is incorrect could lower investment performance. The Fund pays implied brokerage commissions when it purchases or sells bonds, which is the difference between the bid and ask price. As a result, as portfolio turnover increases, the cumulative effect of this may hurt Fund

performance. Under normal circumstances, the Fund will not engage in active or frequent trading of its bonds. However, it is possible that Madison will determine that market conditions require a significant change to the composition of the Fund’s portfolio. For example, if interest rates begin to rise, Madison may attempt to sell bonds in anticipation of further rate increases before they lose more value. Also, if the Fund experiences large swings in shareholder purchases and redemptions, Madison may be required to sell bonds more frequently in order to generate the cash needed to pay redeeming shareholders. Under these circumstances, the Fund could make a taxable capital gain distribution.

Madison reserves the right to invest a portion of the Fund’s assets in short-term debt securities (i.e., those with maturities of one year or less) and to maintain a portion of Fund assets in uninvested cash. However, Madison does not intend to hold more than 35% of the Fund’s assets in such investments, unless Madison determines that market conditions warrant a temporary defensive investment position. Under such circumstances, the Fund may invest up to 100% in cash, money market funds, and/or tax-free money market instruments. To the extent the Fund engages in this temporary defensive position, the Fund’s ability to achieve its investment objective may be diminished. Short-term investments may include investment grade certificates of deposit, commercial paper and repurchase agreements. Madison might hold substantial cash reserves in seeking to reduce the Fund’s exposure to bond price depreciation during a period of rising interest rates and to maintain desired liquidity while awaiting more attractive investment conditions in the bond market.

The Fund’s investment strategy reflects Madison’s general “Participate and Protect^®” investment philosophy.  Madison’s expectation is that investors in the Fund will participate in market appreciation during bull markets and experience something less than full participation during bear markets compared with investors in portfolios holding more speculative and volatile securities; therefore, this investment philosophy is intended to represent a conservative investment strategy. There is no assurance that Madison’s expectations regarding this investment strategy will be realized.

The Fund invests, under normal conditions, primarily in common stocks of large- and mid-capitalization issuers that are, in the view of the Fund’s investment adviser, Madison Asset Management, LLC ("Madison"), selling at a reasonable price in relation to their long-term earnings growth rates. Under normal market conditions, the Fund will seek to generate current earnings from option premiums by writing (selling) covered call options on a substantial portion of its portfolio securities. The Fund seeks to produce a high level of current income and current gains generated from option writing premiums and, to a lesser extent, from dividends.

Under normal market conditions, the Fund will invest at least 80% of its net assets in common stocks, with at least 65% of this amount invested in common stocks of large capitalization issuers that meet the Fund’s selection criteria. In calculating compliance with these percentages, the Fund will "look through" to the characteristics of the underlying holdings of any exchange traded funds ("ETFs") held by the Fund. The Fund may invest the remainder of its common stock investments in companies that meet the Fund’s selection criteria but whose market capitalization is considered to be middle sized or “mid-cap” (generally, stocks with a market capitalization similar to those companies in the Russell Midcap^® Index). In addition, the

Under normal market conditions, the Fund will invest at least 80% of its net assets in common stocks, with at least 65% of this amount invested in common stocks of large capitalization issuers that meet the Fund’s selection criteria.In addition, the Fund may invest up to 15% of its net assets in foreign securities, including American Depositary Receipts (“ADRs”) and emerging market securities. Although Madison believes that, under normal conditions, at least 80% of the Fund will be invested in equity securities, high levels of new investment inflow can lead to periods of higher cash levels which are invested in due course as appropriate opportunities are identified.

Fund may invest up to 15% of its net assets in foreign securities, including American Depositary Receipts (“ADRs”) and emerging market securities. Madison will allocate the Fund’s assets among stocks in sectors of the economy based upon Madison’s views on forward earnings growth rates, adjusted to reflect Madison’s views on economic and market conditions and sector risk factors. In general, Madison focuses its investments in the information technology, consumer discretionary, health care and financials sectors, and may invest up to 35% of the Fund’s net assets in any one such sector. The Fund generally holds 30-60 individual equity and investment company securities, including ETFs and Unit Investment Trusts ("UITs"), in its portfolio at any given time. This reflects Madison's belief that your money should be invested in Madison's top investment ideas, and that focusing on Madison's highest conviction investment ideas is the best way to achieve the Fund’s investment objective.

Although Madison believes that, under normal conditions, at least 80% of the Fund will be invested in equity securities, high levels of new investment inflow can lead to periods of higher cash levels which are invested in due course as appropriate opportunities are identified. In addition, during periods in which stock markets advance, option assignment activity can rise significantly resulting in the exercise of options and the calling away of Fund portfolio securities. Madison believes that reinvesting such sale proceeds should be done carefully and opportunistically such that cash level may remain elevated for relatively short periods of time until appropriate reinvestment opportunities are identified. Additionally, during periods when Madison believes the stock markets in general are overvalued or when there is perceived domestic or global economic or political risk or when investments in equity securities bear an above average risk of loss, Madison will delay investment of some or all of the Fund’s cash until such periods have ended. Thus, in Madison’s discretion, the Fund’s cash may be held for “temporary defensive purposes,” and might represent a material percentage of the Fund’s portfolio. These periods may last for a few weeks or even for a few months, until more attractive market conditions exist.

The Fund will employ an option strategy of writing covered call options on a substantial portion of the common stocks in its portfolio. The extent of option writing activity will depend upon market conditions and Madison’s ongoing assessment of the attractiveness of writing call options on the Fund’s stock holdings. In addition to providing income, covered call writing helps to reduce the volatility (and risk profile) of the Fund by providing downside protection.

In addition to its covered call strategy, the Fund may, to a lesser extent (not more than 20% of its net assets), pursue an option strategy that includes the writing of both put options and call options on certain of the common stocks in the Fund’s portfolio. To seek to offset some of the risk of a larger potential decline in the event the overall stock market has a sizable short-term or intermediate-term decline, the Fund may, to a limited extent (not more than 2% of its total assets) purchase put options or put option debit spreads (where another put option at a lower strike price is sold to offset the cost of the first put option) on broad-based securities indices (such as the S&P 500, S&P MidCap 400 or other indices deemed suitable) or certain ETFs that trade like common stocks but represent such market indices. To seek to offset some of the risk of a larger potential decline in an individual holding due to a binary short term company specific event, the Fund may, to a limited extent (not more than 2% of its total assets) purchase put options on individual equity holdings.

To the extent the Fund engages in this temporary defensive position, the Fund’s ability to achieve its investment objectives may be diminished. 

The Fund seeks to achieve its investment objective by investing in the common stock of established, high-quality companies selected via bottom-up fundamental analysis. Under normal market conditions, the Fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in the securities of large-cap companies. The Fund defines a large-cap company as one whose market capitalizations, at the time of purchase, is within the range of the S&P 500 Index^®, a widely used benchmark of the largest U.S. stocks. The portfolio managers define “high-quality” companies as those businesses that have demonstrated stable revenue and earnings growth patterns and high profitability metrics, and that maintain proportionately low levels of debt. The Fund may also invest up to 35% of its assets in foreign securities (including American Depositary Receipts ("ADRs") and emerging market securities). To the extent invested in common stocks, the Fund generally invests in only 25-40 companies at any given time. This reflects the belief of the Fund's investment adviser, Madison Asset Management, LLC ("Madison"), that your money should be invested in Madison’s top investment ideas, and that focusing on Madison’s best investment ideas is the best way to achieve the Fund’s investment objectives.

Madison follows a rigorous three-step process when evaluating companies pursuant to which Madison considers (1) the business model, (2) the management team, and (3) the valuation of each potential investment. When evaluating the business model, Madison looks for sustainable competitive advantages, metrics that demonstrate relatively high levels of profitability, stable and growing earnings, and a solid balance sheet.

When assessing management, Madison evaluates its operational and capital allocation track records and the nature of its accounting practices. The final step in the process is assessing the proper valuation for the company. Madison strives to purchase securities trading at a discount to their intrinsic value as determined by discounted cash flows modeling and additional valuation methodologies. Often, Madison finds companies that clear the business model and management team hurdles, but not the valuation hurdle. Those companies are monitored for inclusion at a later date when the price may be more appropriate. Madison seeks to avoid the downside risks associated with overpriced securities.

Madison may sell stocks for a number of reasons, including: (i) the price target Madison has set for stock has been achieved or exceeded, (ii) the fundamental business prospects for the company have materially changed, or (iii) Madison finds a more attractive alternative.

The Fund’s investment strategy reflects Madison’s general “Participate and Protect^®” investment philosophy. Madison’s expectation is that investors in the Fund will participate in market appreciation during bull markets and experience something less than full participation during bear markets compared with investors in portfolios holding more speculative and volatile securities; therefore, this investment philosophy is intended to represent a conservative investment strategy.

To the extent the Fund engages in this temporary defensive position, the Fund’s ability to achieve its investment objective may be diminished.

The Fund invests primarily in a diversified mix of common stocks of small cap U.S. companies that are believed to be undervalued by various measures and offer sound prospects for capital appreciation. For purposes of this Fund, “small cap” is defined as those companies with market capitalization of between $100 million and $15 billion. Under normal market conditions, the Fund will maintain at least 80% of its net assets (including borrowings for investment purposes) in small cap securities.

The Fund's investment adviser, Madison Asset Management, LLC ("Madison"), focuses on core growth strategies through bottom-up fundamental research analysis to identify stocks of businesses that are selling at what it believes are substantial discounts to prices that accurately reflect their future earnings prospects. Madison conducts extensive research on each prospective investment using a five pillar analysis process to evaluate companies as potential investments for the portfolio. Investments that meet most of the criteria are added to a list of similar companies to be

monitored by Madison. Companies meeting all five pillars may be added to the portfolio. The five pillars of the analysis are: (1) strong business traits, (2) defendable market niche, (3) attractive growth potential, (4) capable management, and (5) discount to private market value. In reviewing companies, Madison applies the characteristics identified above on a case-by-case basis as the order of importance varies depending on the type of business or industry and the company being reviewed. As a result of employing the five pillar analysis, the Fund may hold cash opportunistically, particularly during periods of market uncertainty when investments meeting all five pillars may be difficult to identify.

Madison may generally sell a security when it believes: (1) the security has achieved its value potential; (2) such sale is necessary for portfolio diversification, (3) changing fundamentals signal a deteriorating value potential; or (4) other securities have a better value potential.
