SUMMARY

1

Investment Objective(s)

The fund seeks high current income and, secondarily, capital appreciation.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below.

Fees and Expenses of the Fund
Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees		0.50	%
Other expenses		-
Total annual fund operating expenses		0.50

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 time periods indicated and then redeem all of your shares at the end of those periods, 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:

		1 Year			3 Years			5 Years			10 Years
	$	51		$	160		$	280		$	628

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 the fund's 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 41.3% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in a widely diversified portfolio of high yield corporate bonds, often called "junk" bonds, as well as income-producing convertible securities and preferred stocks that are rated below investment grade or not rated by any major credit rating agency but deemed by the adviser to be below investment grade. Any derivatives that provide exposure to the investment focus suggested by the fund's name, or to one or more market risk factors associated with the investment focus suggested by the fund's name, are counted (as applicable) toward compliance with the fund's 80% investment policy.

High yield bonds are rated below investment grade (BB and lower, or an equivalent rating), and tend to provide high income in an effort to compensate investors for their higher risk of default, which is the failure to make required interest or principal payments. If a holding is split rated (i.e., rated investment grade by at least one credit rating agency and below investment grade by another credit rating agency), the lower rating will be used for purposes of the fund's 80% investment policy. High yield bond issuers include small or relatively new companies lacking the history or capital to merit investment-grade status, former blue chip companies downgraded because of financial problems, companies electing to borrow heavily to finance or avoid a takeover or buyout, and firms with heavy debt loads.

The fund may invest up to 15% of its total assets in bank loans. While high yield corporate bonds are typically issued with a fixed interest rate, bank loans have floating interest rates that reset periodically (typically quarterly or monthly). Bank loans represent amounts borrowed by companies or other entities from banks and other lenders. In many cases, the borrowing companies have significantly more debt than equity and the loans have been issued in connection with recapitalizations, acquisitions, leveraged buyouts, or refinancings. The loans held by the fund may be senior or subordinate obligations of the borrower.

The fund may purchase securities of any maturity and its weighted average maturity will vary with market conditions. In selecting investments, the fund relies extensively on the adviser's credit research analysts. The fund focuses primarily on the higher-quality range (BB and B, or an equivalent rating) of the high yield market.

While most assets are typically invested in U.S. dollar-denominated bonds, the fund may also invest in bonds of foreign issuers (including securities of issuers in emerging markets). The fund may invest up to 20% of its total assets in non-U.S. dollar-denominated securities and may invest without limitation in U.S. dollar-denominated bonds of foreign issuers.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund's share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater in unfavorable or uncertain market conditions, are summarized as follows:

Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative.

Junk bonds: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, and loans that are rated below investment grade, expose the fund to greater volatility and credit risk than investments in securities that are rated investment grade. As a result, bonds and loans rated below investment grade carry a higher risk of default and should be considered speculative.

SUMMARY

Fixed income markets: Economic and other market developments can adversely affect the fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund's ability to sell the debt instruments in which it invests or to find and purchase suitable debt instruments.

Market conditions: The value of the fund's investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund's holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as pandemics) and related governmental and public responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

Bank loans: Investments in bank loans expose the fund to additional risks beyond those normally associated with more traditional debt instruments. The fund's ability to receive payments in connection with a loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Transactions involving bank loans may have significantly longer settlement periods than more traditional investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the fund may not receive its proceeds in a timely manner or that the fund may incur losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered under the federal securities laws like stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities.

Covenant lite loans: Because covenant lite loans contain few or no financial maintenance covenants, they may not include terms that permit the lender of the loan to monitor the borrower's financial performance and, if certain criteria are breached, declare a default, which would allow the lender to restructure the loan or take other action intended to help mitigate losses. As a result, the fund could experience relatively greater difficulty or delays in enforcing its rights on its holdings of covenant lite loans than its holdings of loans or securities with financial maintenance covenants, which may result in losses, especially during a downturn in the credit cycle.

Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.

Callable bonds: While a rise in interest rates is the principal source of interest rate risk for bond funds, falling rates bring the possibility that a bond may be "called," or redeemed before maturity, and that the proceeds may need to be reinvested in lower-yielding securities.

Foreign investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. Investments in emerging market countries are subject to greater risk and overall volatility than investments in developed markets.

Liquidity: The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders' interests in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund's ability to sell a holding at a suitable price.

Convertible securities and preferred stocks: Convertible securities and preferred stocks carry credit and interest rate risk, along with other risks associated with both equity and fixed income securities, and convertible securities may be called back by the issuer prior to maturity at a price that is disadvantageous to the fund.

Active management: The fund's overall investment program and holdings selected by the fund's investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund's assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund's service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. A cybersecurity breach could result in a loss for the fund or affect its ability to operate as intended either temporarily or for an extended period, which may include limits on the ability to obtain pricing information for the fund's investments, calculate its net asset value, and satisfy redemptions.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund's performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund. Returns for other share classes vary since they have different expenses.

		Quarter Ended	Total Return			Quarter Ended	Total Return
	Best Quarter	6/30/20	10.12%		Worst Quarter	3/31/20	-13.62%

The fund's return for the six months ended 6/30/26 was 1.83%.

The following table shows the average annual total returns for the fund. The fund's performance information included in the table is compared with a regulatory required index that represents an overall securities market (Bloomberg U.S. Aggregate Bond Index). In addition, the table may also include one or more indexes that align to the fund's investment strategy.

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. After-tax returns are calculated using the historical highest 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. 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 an IRA.

Tax Information

The fund declares dividends, if any, daily and pays them on the first business day of each month. Any capital gains are declared and paid annually, usually in December. Redemptions or exchanges of fund shares and distributions by the fund, whether or not you reinvest these amounts in additional fund shares, generally may be taxed as ordinary income or capital gains unless you invest through a tax-deferred account (in which case you will be taxed upon withdrawal from such account).

Payments 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), the fund and its related companies 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 salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
