The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same (except that fee waivers or reimbursements, if any, are only reflected in the 1-Year figures) and that all dividends and distributions are reinvested. Your actual costs may be higher or lower. If Shares Are Redeemed 405 581 773 1326 265 517 894 1736 59 194 342 770 50 175 310 706 If Shares Are Not Redeemed 405 581 773 1326 165 517 894 1736 59 194 342 770 50 175 310 706 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 Fund's most recent fiscal year, the Fund's portfolio turnover rate was 68% of the average value of its portfolio. 0.68 INVESTMENTS, RISKS AND PERFORMANCEPrincipal Investment Strategies. The Fund invests, under normal circumstances, at least 80% of its investable assets (net assets plus any borrowing for investment purposes) in municipal bonds, which are fixed income securities issued by states and municipalities whose income is free from regular federal income tax. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions.The subadviser normally invests the Fund's investable assets in municipal bonds that it believes may provide above-average yields. While the Fund may purchase municipal bonds of any credit quality, the portfolio consists primarily of municipal bonds which are rated B or better by Moody's Investors Service, Inc. (“Moody's”) or S&P Global Ratings (“S&P”) or bonds with a comparable rating by another major rating service or unrated bonds judged by the subadviser to be of comparable quality. Bonds rated Ba1 or lower by Moody's or BB+ or lower by S&P are considered to be speculative with respect to their capacity to make interest and principal payments and are commonly referred to as junk bonds. Bonds rated Baa3 and higher by Moody's or BBB- and higher by S&P are considered investment grade, with a range of adequate to very strong capacity for meeting their financial obligations, although municipal bonds rated in the Baa rating category by Moody's or BBB rating category by S&P have certain speculative characteristics and are riskier than higher-rated municipal bonds. The municipal bonds in which the Fund invests generally have maturities in excess of 10 years at the time of purchase, although the Fund also invests in municipal bonds having maturities ranging from one year to 10 years. As of August 31, 2024, the Fund's weighted average maturity was 16.23 years. The Fund's investments may include certain municipal bonds, the interest on which is subject to the federal alternative minimum tax (“AMT”).In determining which securities to buy and sell, the subadviser considers, among other things, fundamental research, yield, maturity, issue, quality characteristics and expectations regarding economic and political developments, including movements in interest rates and demand for municipal bonds. The subadviser may trade securities based on its outlook on interest rates. The subadviser also seeks to take advantage of differentials in yields with respect to securities with similar credit ratings and maturities, but which vary according to the purpose for which they were issued, as well as securities issued for similar purposes with similar maturities, but which vary according to ratings.In managing the Fund’s assets, the subadviser uses a combination of top-down economic analysis and bottom-up research in conjunction with proprietary quantitative models and risk management systems. In the top-down economic analysis, the subadviser develops views on economic, policy and market trends. In its bottom-up research, the subadviser develops an internal rating and outlook on issuers. The rating and outlook are determined based on a thorough review of the financial health and trends of the issuer. The subadviser may also consider investment factors such as expected total return, yield, spread and potential for price appreciation as well as credit quality, maturity and risk. Principal Risks. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; and is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Credit Risk. This is the risk that the issuer, the guarantor, or the insurer of a fixed income security, or the counterparty to a contract may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, fixed income securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer, or counterparty to pay back debt. The lower the credit quality of a bond, the more sensitive it is to credit risk. Debt Obligations Risk. Debt obligations are fixed income investments that are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to bond market movements. The value of bonds may decline for issuer-related reasons, including management performance, financial leverage and reduced demand for the issuer’s goods and services. Certain types of fixed income obligations also may be subject to “call and redemption risk,” which is the risk that the issuer may call a bond held by the Fund for redemption before it matures and the Fund may not be able to reinvest at the same rate of interest and therefore would earn less income. Economic and Market Events Risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth or the functioning of the securities markets, or otherwise reduce inflation, may at times result in unusually high market volatility, which could negatively impact performance. Governmental efforts to curb inflation often have negative effects on the level of economic activity. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide. Increase in Expenses Risk. Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses. Insured Municipal Bonds Risk. The Fund may purchase municipal bonds that are insured to attempt to reduce credit risk. Although insurance coverage reduces credit risk by providing that the insurer will make timely payment of interest and/or principal, it does not provide protection against market fluctuations of insured bonds or fluctuations in the price of the shares of the Fund. An insured municipal bond fluctuates in value largely based on factors relating to the insurer's creditworthiness or ability to satisfy its obligations. The Fund cannot be certain that any insurance company will make the payments it guarantees. Interest Rate Risk. The value of your investment may go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration debt securities. Similarly, a rise in interest rates may also have a greater negative impact on the value of equity securities whose issuers expect earnings further out in the future. For example, a fixed income security with a duration of three years is expected to decrease in value by approximately 3% if interest rates increase by 1%. This is referred to as “duration risk.” When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as “prepayment risk.” For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be elevated. When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as “extension risk.” The Fund may lose money if short-term or long-term interest rates rise sharply or in a manner not anticipated by the subadviser. Junk Bonds Risk. High-yield, high-risk bonds have predominantly speculative characteristics, including particularly high credit risk. Junk bonds tend to have lower market liquidity than higher-rated securities. The liquidity of particular issuers or industries within a particular investment category may shrink or disappear suddenly and without warning. The non-investment grade bond market can experience sudden and sharp price swings and become illiquid due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high profile default or a change in the market's psychology. Large Shareholder and Large Scale Redemption Risk. Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents. Liquidity Risk. Liquidity risk is the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investors' interests in the Fund. The Fund may invest in instruments that trade in lower volumes and are more illiquid than other investments. If the Fund is forced to sell these investments to pay redemption proceeds or for other reasons, the Fund may lose money. In addition, when there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities. Management Risk. Actively managed funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but the subadviser's judgments about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements may be incorrect. Additionally, the investments selected for the Fund may underperform the markets in general, the Fund's benchmark and other funds with similar investment objectives. Market Disruption and Geopolitical Risks. Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraineand the Israel-Hamas war), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally).The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero. Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline. Municipal Bonds Risk. Municipal bonds are subject to credit risk, market risk and interest rate risk. The Fund's holdings, share price, yield and total return may also fluctuate in response to municipal bond market movements. Municipal bonds are also subject to the risk that potential future legislative changes relating to tax or the rights of municipal bond holders, for example in connection with an insolvency, could affect the market for and value of municipal bonds, which may adversely affect the Fund's yield or the value of the Fund's investments in municipal bonds. Certain municipal bonds with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project's ability to make payments of principal and interest on these securities. If the Fund invests a substantial amount of its assets in issuers located in a single region, state or city, there is an increased risk that environmental, economic, political and social conditions in those regions will have a significant impact on the Fund's investment performance. For example, municipal securities of a particular state are vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health epidemics, social unrest and catastrophic natural disasters, such as hurricanes or earthquakes. Many municipal bonds are also subject to prepayment risk, which is the risk that when interest rates fall, issuers may redeem a security by repaying it early, which may reduce the Fund's income if the proceeds are reinvested at a lower interest rate. In addition, income from municipal bonds could be declared taxable because of non-compliant conduct of a bond issuer. Performance.
