Investment Objective

The Madison Conservative Allocation Fund seeks income, capital appreciation and relative stability of value.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts if you and your immediate family invest, or agree to invest in the future, at least $25,000 in Madison Funds. More information about these and other discounts is available from your financial professional, in the “Your Account - Sales Charges and Fees” section on page 77 of the prospectus and in the “More About Purchasing and Selling Shares” section on page 54 of the statement of additional information.

¹ The CDSC is reduced after 12 months and eliminated after six years following purchase.

² The CDSC is eliminated after 12 months following purchase.

³ Acquired fund fees and expenses have been updated to reflect current fees associated with investing in the underlying funds.

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 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 total annual fund operating expenses or in the expense examples above, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies

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 35% equity investments and 65% 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, 2017, the fund’s asset allocation was:

- Bond Funds:    59.1%

- Stock Funds:    23.1%

- Foreign Stock Funds:    13.7%

- Alternative Funds:    2.0%

- Money Market Funds:    2.1%

With regard to investments in debt securities, Madison’s bias is toward securities with intermediate and short-term maturities. As of December 31, 2017, the weighted average duration of the fund’s debt portfolio was 6.12 years.

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

In addition, Madison has a flexible mandate which permits the fund, at the sole discretion of the manager, 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 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.

Principal Risks

The fund is a fund of funds, meaning that it invests primarily in the shares of underlying funds, including ETFs. Thus, the fund’s investment performance and its ability to achieve its investment goal are directly related to the performance of the underlying funds in which it invests. Each underlying fund’s performance, in turn, depends on the particular securities in which that underlying fund invests and the expenses of that underlying fund. Accordingly, the fund is subject to the risks of the underlying funds in direct proportion to the allocation of its assets among the underlying funds.

The specific risks of owning the fund are set forth below.  You could lose money as a result of investing in the fund. 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, entity or person.  The fund’s share price and total return will fluctuate.  You should consider your own investment goals, time horizon and risk tolerance before investing in the fund. 

Asset Allocation Risk . The fund is subject to asset allocation risk, which is the risk that the selection of the underlying funds and the allocation of the fund’s assets among the various asset classes and market segments will cause the fund to underperform other funds with a similar investment objective.

Market Risk . While the majority of the fund’s assets will typically be invested in underlying funds that invest primarily in debt securities, to the extent that the fund invests in underlying funds that invest in equities, the fund is subject to market risk, which is the risk that the value of an investment may fluctuate in response to stock market movements.

Interest Rate Risk . The fund, through the underlying funds, is subject to interest rate risk , which is the risk that the value of your investment will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the market value of income-bearing securities. When interest rates rise, bond prices fall; generally, the longer a bond’s maturity, the more sensitive it is to this risk.

Credit and Prepayment/Extension Risk . The fund, through the underlying funds, is also subject to credit risk, which is the risk that issuers of debt securities may be unable to meet their interest or principal payment obligations when due. There is also prepayment/extension risk, which is the chance that a rise/fall in interest rates will reduce/extend the life of a mortgage-backed security by increasing/decreasing mortgage prepayments, typically reducing the underlying fund’s return.

Non-Investment Grade Security Risk . The fund, through the underlying funds, may invest in non-investment grade securities (i.e., “ junk” bonds). Issuers of non-investment grade securities are typically in weak financial health and their ability to pay interest and principal is uncertain. Compared to issuers of investment-grade bonds, they are more likely to encounter financial difficulties and to be materially affected by these difficulties when they do encounter them. “Junk” bond markets may react strongly to adverse news about an issuer or the economy, or to the perception or expectation of adverse news.

Equity Risk . The fund, through the underlying funds, is subject to equity risk. Equity risk is the risk that securities held by the fund will fluctuate in value due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the fund participate, and the particular circumstances and performance of particular companies whose securities the fund holds. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

ETF Risks . The main risks of investing in ETFs are the same as investing in a portfolio of equity securities comprising the index on which the ETF is based, although lack of liquidity in an ETF could result in it being more volatile than the securities comprising the index. Additionally, the market prices of ETFs will fluctuate in accordance with both changes in the market value of their underlying portfolio securities and due to supply and demand for the instruments on the exchanges on which they are traded (which may result in their trading at a discount or premium to their net asset values). Index-based ETF investments may not replicate exactly the performance of their specific index because of transaction costs and because of the temporary unavailability of certain component securities of the index.

Foreign Security and Emerging Market Risk . Investments of underlying funds that invest in foreign securities involve risks relating to currency fluctuations and to political, social and economic developments abroad, as well as risks resulting from differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks may be greater in emerging markets. The investment markets of emerging countries are generally more volatile than markets of developed countries with more mature economies.

Payment to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank or trust company), the fund and the fund’s distributor or its affiliates may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial adviser to recommend the fund over another investment. Ask your individual financial adviser or visit your financial intermediary’s website for more information.

Market Risk . The fund, through the underlying funds, is subject to market risk, which is the risk that the value of an investment may fluctuate in response to stock market movements. Certain of the underlying funds may invest in the equity securities of smaller companies, which may fluctuate more in value and be more thinly traded than the general market.

A higher portfolio turnover 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 total annual fund operating expenses or in the expense examples above, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

The fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including borrowings for investment purposes) in municipal bonds that are exempt from federal and state income tax for residents of Virginia. These securities may be issued by state governments, their political subdivisions (for example, cities and counties) and public authorities (for example, school districts and housing authorities). The fund may also invest in bonds that, under federal law, are exempt from federal and state income taxation, such as bonds issued by the District of Columbia, Puerto Rico, the Virgin Islands and Guam. The fund only invests in investment grade bonds, which means bonds rated in the top four rating categories by a nationally recognized statistical rating organization, such as Moody’s, S&P or Fitch; however, if a bond is downgraded below investment grade, the fund may need to hold the bond for a period of time in an attempt to avoid selling it at a “fire sale” price. The fund invests in general obligation bonds of states and municipalities (backed by the general credit of the issuing city, state or county) and specific or limited purpose bonds (supported by, for example, a specific power company, hospital or highway project).

The fund invests in intermediate and long-term bonds having average, aggregate maturities (at the portfolio level) of 7 to 15 years. The fund’s weighted average life as of December 31, 2017 was 6.41 years. Under normal market conditions, the fund will have an average duration range of 3 to 10 years, although it is expected to center around 3 to 7 years. Duration is an approximation of the expected change in a debt security’s price given a 1% move in interest rates, using the following formula: [change in debt security value = (change in interest rates) x (duration) x (-1)]. By way of example, assume XYZ company issues a five year bond which has a duration of 4.5 years. If interest rates were to instantly increase by 1%, the bond would be expected to decrease in value by approximately 4.5%. Securities are selected for the fund that, in the opinion of the portfolio managers, provide the highest combination of yield (i.e., the interest rate the bond pays in relation to its price), credit risk and diversification. To a lesser extent, consideration is also given as to whether a particular bond may increase in value from its price at the time of purchase. The fund generally holds 50-75 individual securities in its portfolio at any given time. This reflects the belief of the fund's investment adviser that your money should be invested in the adviser’s top investment ideas, and that focusing on the adviser's best investment ideas is the best way to achieve the fund’s investment objectives.

In the event the fund’s investment adviser, Madison Asset Management, LLC (“Madison”), determines that extraordinary conditions exist (such as tax law changes or a need to adopt a defensive investment position) making it advisable to invest a larger portion of the fund’s assets in taxable investments, more than 20% and even as much as 100% of the fund’s assets could be invested in securities whose income is taxable on the federal or state level. If this situation were to occur, the fund would not be invested in a manner designed to achieve its investment objective.

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 tax-free money market instruments. To the extent the fund engages in this temporary defensive position, the fund’s ability to achieve its investment objectives may be diminished.

Principal Risks

The specific risks of owning the fund are set forth below.  You could lose money as a result of investing in the fund. 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, entity or person.  The fund’s share price and total return will fluctuate.  You should consider your own investment goals, time horizon and risk tolerance before investing in the fund. 

Interest Rate Risk . As with most income funds, the fund is subject to interest rate risk, which is the risk that the value of your investment will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the market value of income bearing securities. When interest rates rise, bond prices fall; generally, the longer the bond’s maturity, the more sensitive it is to this risk.

Call Risk. If a bond issuer “calls” a bond held by the fund (i.e., pays it off at a specified price before it matures), the fund could have to reinvest the proceeds at a lower interest rate. It may also experience a loss if the bond is called at a price lower than what the fund paid for the bond.

Risk of Default. Although the fund’s investment adviser monitors the condition of bond issuers, it is still possible that unexpected events could cause the issuer to be unable to pay either principal or interest on its bond. This could cause the bond to go into default and lose value. Some federal agency securities are not backed by the full faith and credit of the United States, so in the event of default, the fund would have to look to the agency issuing the bond for ultimate repayment.

Liquidity Risk . The fund is also subject to liquidity risk, which means there may be little or no trading activity for the debt securities in which the fund invests, and that may make it difficult for the fund to value accurately and/or sell those securities. In addition, liquid debt securities in which the fund invests are subject to the risk that during certain periods their liquidity will shrink or disappear suddenly and without warning as a result of adverse economic, regulatory or market conditions, or adverse investor perceptions. If the fund experiences rapid, large redemptions during a period in which a substantial portion of its debt securities are illiquid, the fund may be forced to sell those securities at a discount, which could result in significant fund and shareholder losses. Liquidity risk may be higher for this fund than those of income funds that hold U.S. government securities as part of their portfolios because the liquidity of U.S. government securities has historically continued in times of recent market stress.  This fund normally holds few or no U.S. government securities.

Legislative Risk. Municipal bonds pay lower rates of interest than comparable corporate bonds because of the tax-free nature of their interest payments. If the tax-free status of municipal securities is altered or eliminated by an act of Congress or the legislature of any particular state, the value of the affected bonds will drop. This is because their low interest payments will be less competitive with other taxable bonds.

Capital Gains Tax-Related Risk . While dividend income is expected to be tax-free, fund shareholders can recognize taxable income in two ways: (1) if you sell your shares at a price that is higher than when you bought them, you will have a taxable capital gain; on the other hand, if you sell your shares at a price that is lower than the price when you bought them, you will have a capital loss; and (2) in the event the fund sells more securities at prices higher than when they were bought by the fund, the fund may pass through the profit it makes from these transactions by making a taxable capital gain distribution.

Alternative Minimum Tax (AMT) Risk. In addition to possible taxable capital gain distributions, certain bonds owned by the fund generate income that is subject to the federal AMT. The interest on these “private activity” bonds could become subject to AMT if you are a taxpayer that meets the AMT criteria. If you are subject to AMT, you will be required to add any income attributable to these bonds (as reported by the fund annually) to other so-called “tax preference items” to determine possible liability for AMT. Income from AMT bonds may not exceed 20% of the fund’s net income.

Risks of General Obligation versus Limited Purpose Bonds . General obligation bonds are backed by the unlimited taxing powers of the municipality issuing the bonds. Limited purpose bonds or “limited tax general obligation bonds” are more risky because the pledged tax revenues backing the bonds are limited to revenue sources and maximum property tax millage amounts. For example, a bond issued by the Commonwealth of Virginia has an unlimited tax pledge backing the debt service, while a bond issued for Arlington, Virginia Public School system has a limited revenue source which is property taxes in the district.

Virginia-Specific Risks . Particular risks to consider when investing in Virginia securities are:

Investment Objective

The Madison Tax-Free National Fund seeks to receive income from municipal bonds and to distribute that income to shareholders as tax-free dividends.

Example :

The following 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 you invest $10,000 in the fund for the time periods indicated and then redeem your shares at the end of the period. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. 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 may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account.

The example assumes you invest $10,000 in the fund for the time periods indicated and then redeem your shares at the end of the period. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. 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 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 total annual fund operating expenses or in the expense examples above, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategies

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 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, 2017 was 3.16 years. The fund generally holds 45-60 individual securities in its portfolio at any given time. This reflects the belief of the fund's investment adviser that your money should be invested in the adviser’s top investment ideas, and that focusing on the adviser's best investment ideas is the best way to achieve the fund’s investment objective.

The fund’s investment adviser, Madison Asset Management, LLC (“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, up to 100% of the fund may be so invested. 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.

Principal Risks

The specific risks of owning the fund are set forth below.  You could lose money as a result of investing in the fund. 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, entity or person.  The fund’s share price and total return will fluctuate.  You should consider your own investment goals, time horizon and risk tolerance before investing in the fund.

Foreign Security and Emerging Market Risk . Investments in foreign securities involve risks relating to currency fluctuations and to political, social and economic developments abroad, as well as risks resulting from differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks may be greater in emerging markets. The investment markets of emerging countries are generally more volatile than markets of developed countries with more mature economies.

Investment Objective

The Madison Core Bond Fund seeks to generate a high level of current income, consistent with the prudent limitation of investment risk.

The following 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 you invest $10,000 in the fund for the time periods indicated and then either redeem or not redeem your shares at the end of the period. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. 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 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 total annual fund operating expenses or in the expense examples above, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the fund invests at least 80% of its net assets (including borrowings for investment purposes) in bonds. To keep current income relatively stable and to limit share price volatility, the fund emphasizes investment grade securities and maintains an intermediate (typically 3-7 year) average portfolio duration, with the goal of being between 85-115% of the market benchmark duration (for this purpose, the benchmark used is Bloomberg Barclays U.S. Aggregate Bond Index, the duration of which as of December 31, 2017 was 5.93 years). Duration is an approximation of the expected change in a debt security’s price given a 1% move in interest rates, using the following formula: [change in debt security value = (change in interest rates) x (duration) x (-1)]. By way of example, assume XYZ company issues a five year bond which has a duration of 4.5 years. If interest rates were to instantly increase by 1%, the bond would be expected to decrease in value by approximately 4.5%.

The fund is managed so that, under normal market conditions, the weighted average life of the fund will be 10 years or less. The weighted average life of the fund as of December 31, 2017 was 7.48 years. The fund strives to add incremental return in the portfolio by making strategic decisions relating to credit risk, sector exposure and yield curve positioning. The fund generally holds 150-275 individual securities in its portfolio at any given time and may invest in the following instruments:

Madison may alter the composition of the fund with regard to quality and maturity and may sell securities prior to maturity. Under normal market conditions, 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.

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.

Principal Risks

The specific risks of owning the fund are set forth below.  You could lose money as a result of investing in the fund. 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, entity or person.  The fund’s share price and total return will fluctuate.  You should consider your own investment goals, time horizon and risk tolerance before investing in the fund. 

Interest Rate Risk . As with most income funds, the fund is subject to interest rate risk, which is the risk that the value of your investment will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the market value of income bearing securities. When interest rates rise, bond prices fall; generally, the longer the bond’s maturity, the more sensitive it is to this risk.

Call Risk. If a bond issuer “calls” a bond held by the fund (i.e., pays it off at a specified price before it matures), the fund could have to reinvest the proceeds at a lower interest rate. It may also experience a loss if the bond is called at a price lower than what the fund paid for the bond.

Risk of Default. Although the fund’s investment adviser monitors the condition of bond issuers, it is still possible that unexpected events could cause the issuer to be unable to pay either principal or interest on its bond. This could cause the bond to go into default and lose value. Some federal agency securities are not backed by the full faith and credit of the United States, so in the event of default, the fund would have to look to the agency issuing the bond for ultimate repayment.

Mortgage-Backed Securities Risk . The fund may own obligations backed by mortgages issued by a government agency or through a government-sponsored program. If the mortgage holders prepay principal during a period of falling interest rates, the fund could be exposed to prepayment risk. In that case, the fund would have to reinvest the proceeds at a lower interest rate. The security itself may not increase in value with the corresponding drop in rates since the prepayment acts to shorten the maturity of the security.

Liquidity Risk . The fund is also subject to liquidity risk, which means there may be little or no trading activity for the debt securities in which the fund invests, and that may make it difficult for the fund to value accurately and/or sell those securities. In addition, liquid debt securities in which the fund invests are subject to the risk that during certain periods their liquidity will shrink or disappear suddenly and without warning as a result of adverse economic, regulatory or market conditions, or adverse investor perceptions. If the fund experiences rapid, large redemptions during a period in which a substantial portion of its debt securities are illiquid, the fund may be forced to sell those securities at a discount, which could result in significant fund and shareholder losses.

Credit Risk and Prepayment/Extension Risk . The fund is subject to credit risk, which is the risk that issuers of debt securities may be unable to meet their interest or principal payment obligations when due. There is also prepayment/extension risk, which is the chance that a fall/rise in interest rates will reduce/extend the life of a mortgage-backed security by increasing/decreasing mortgage prepayments, typically reducing the fund’s return.

Non-Investment Grade Security Risk . To the extent that the fund invests in non-investment grade securities, the fund is also subject to above-average credit, market and other risks. Issuers of non-investment grade securities (i.e., “junk” bonds) are typically in weak financial health and their ability to pay interest and principal is uncertain. Compared to issuers of investment grade bonds, they are more likely to encounter financial difficulties and to be materially affected by these difficulties when they do encounter them. “Junk” bond markets may react strongly to adverse news about an issuer or the economy, or to the perception or expectation of adverse news.

Derivatives Risk. The risk that loss may result from investments in options, forwards, futures, swaps and other derivatives instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the fund. Derivatives are also subject to counterparty risk, which is the risk that the other party to the transaction will not fulfill its contractual obligations.

Foreign Security and Emerging Market Risk . Investments in foreign securities involve risks relating to currency fluctuations and to political, social and economic developments abroad, as well as risks resulting from differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks may be greater in emerging markets. The investment markets of emerging countries are generally more volatile than markets of developed countries with more mature economies.
