(1)

The Sub-Advisory Fee is a fulcrum fee with a base or fulcrum of 32 bps (0.32%) and can range from 0.22% to 0.42% based on the Fund's performance relative to the Bloomberg U.S. Corporate High-Yield Bond Ba/B 2% Issuer Capped Index, the Fund's Benchmark.

(2)

Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial highlights because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.

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. 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 upon these assumptions your costs would be:

Class	1 Year	3 Years	5 Years	10 Years
Class A	$582	$861	$1,161	$2,011
Class C	$189	$585	$1,006	$2,180
Class N	$113	$353	$612	$1,352

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 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 69% of the average value of its portfolio.

Principal Investment Strategies: The Fund's Sub-Adviser seeks to achieve the Fund's investment objectives by investing primarily in lower-rated (generally rated BB and B), and unrated, higher-risk corporate bonds of any maturity. The Fund normally invests at least 80% of its assets (defined as net assets plus any borrowing for investment purposes) in debt securities and convertible securities rated below investment grade (rated BB+ or lower) by S&P or comparably rated by another nationally recognized statistical rating organization (NRSRO), also known as "high-yield" or "junk" bonds, and in unrated debt securities determined by the Sub-Adviser to be of comparable quality. These securities may be issued in reliance on Rule 144A under the Securities Act of 1933, and subject to restriction on resale.

The Fund's Sub-Adviser selects investments and seeks to reduce risk through portfolio diversification, credit analysis and attention to current developments in economic conditions. In general, the Sub-Adviser typically buys high-yield securities that provide high current income that it believes possess attractive risk/reward characteristics. The Sub-Adviser measures a security's risk/reward ratio by its yield and expected probability of default when compared to a peer group of securities with similar credit risk. The Sub-Adviser typically will sell securities when, in the Sub-Adviser's view, they no longer meet the buy criteria and when an issuer's credit fundamentals deteriorate.

The Fund may also engage in securities lending.

Principal Investment Risks: As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Although the Fund will strive to meet its investment objective, there is no assurance that it will do so. Many factors affect the Fund's net asset value and performance.

Lower-Rated Securities Risk - Securities rated below investment-grade, sometimes called "high-yield" or "junk" bonds, are speculative investments that generally have more credit risk than higher-rated securities. Companies issuing high yield fixed-income securities are not as strong financially as those issuing securities with higher credit ratings and are more likely to encounter financial difficulties. Lower rated issuers are more likely to default and their securities could become worthless.

Credit Risk - Issuers of debt securities may suffer from a reduced ability to repay their interest and principal obligations. They may even default on interest and/or principal payments due to the Fund. An increase in credit risk or a default will cause the value of Fund debt securities to decline. Issuers with lower credit quality are more susceptible to economic or industry downturns and are more likely to default.

Interest Rate Risk - In general, the price of a debt security falls when interest rates rise. Debt securities have varying levels of sensitivity to changes in interest rates. Securities with longer maturities may be more sensitive to interest rate changes.

Call or Redemption Risk - If interest rates decline, issuers of debt securities may exercise redemption or call provisions. This may force the Fund to reinvest redemption or call proceeds in securities with lower yields, which may reduce Fund performance.

Changing Fixed Income Market Conditions Risk - During periods of sustained rising rates, fixed income risks will be amplified. If the U.S. Federal Reserve's Federal Open Market Committee ("FOMC") raises the federal funds interest rate target, interest rates across the U.S. financial system may rise. Rising rates tend to decrease liquidity, increase trading costs, and increase volatility, all of which make portfolio management more difficult and costly to the Fund and its shareholders.

Private Placement Risk - Privately issued securities, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, are restricted securities that are not registered with the U.S. Securities and Exchange Commission ("SEC"). Accordingly, the liquidity of the market for specific privately issued securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Privately issued securities that the Sub-Adviser determines to be "illiquid" are subject to the Fund's policy of not investing more than 15% of its net assets in illiquid securities.

Natural Disaster/Epidemic Risk - Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis, and other severe weather-related phenomena generally, and widespread disease and illness, including pandemics and epidemics (such as the novel coronavirus), have been and can be highly disruptive to economies and markets.

Liquidity Risk - Some securities may have few market-makers and low trading volume, which tend to increase transaction costs and may make it impossible for the Fund to dispose of a security position at all or at a price which represents current or fair market value.

Management Risk - The Fund is subject to management risk because it is an actively managed investment portfolio. The Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its decisions will produce the intended result. The successful use of hedging and risk management techniques may be adversely affected by imperfect correlation between movements in the price of the hedging vehicles and the securities being hedged.

Securities Lending Risk - The risk of securities lending is that the financial institution that borrows securities from the Fund could go bankrupt or otherwise default on its commitment under the securities lending agreement and the Fund might not be able to recover the loaned securities or their value.

Performance: The following bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the performance of Class N Shares of the Fund from year to year and by showing how the Fund's Class A, Class C and Class N average annual returns compare with those of a broad measure of market performance. The Class A sales charge is reflected in the average annual total return table. Past performance (before and after taxes) does not necessarily indicate how a Fund will perform in the future.

*

The Morningstar High-Yield Bond Category is generally representative of mutual funds that primarily invest in U.S. high-income debt securities where at least 65% or more of bond assets are not rated or are rated by a major agency such as Standard & Poor's or Moody's at the level of BB (considered speculative for taxable bonds) and below.

After-tax returns are estimated and are based on the highest historical individual federal marginal income tax rates, and do not reflect the impact of state and local taxes; actual after-tax returns depend on an individual investor's tax situation and are likely to differ from those shown. If you own shares of the Fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information is not applicable to your investment, because such accounts are only subject to taxes upon distribution. In certain cases, after-tax returns may be higher than the other return figures for the same period. After tax returns for Class C and Class A shares, which are not shown, will vary from those of Class N shares.

Tax Information

Dividends and capital gain distributions you receive from a Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan.

Financial Intermediary Compensation

If you purchase a 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.
