¹ SEC yield is a measure of the income generated by the portfolio's underlying asset over the trailing 30 days, relative to the asset base of the portfolio itself. The SEC 30-day yield -Subsidized (Sub.) reflects current fee waivers in effect. Absent such fee waivers, the yield would have been lower. The SEC 30-Day yield- Unsubsidized (Unsub.) does not reflect the fee waivers currently in effect.

² Where the net expense ratio is lower than the gross expense ratio, certain fees have been waived and/or expenses reimbursed. These waivers and/or reimbursements will continue for at least one year from the date of the applicable fund's current prospectus (unless otherwise noted in the applicable prospectus) or until such time as the fund's Board of Directors acts to discontinue all or a portion of such waivers and/or reimbursements. Absent such waivers and/or reimbursements, returns would have been lower. Expenses are based on the fund's current prospectus.

See the Fund's prospectus for information related to a primary benchmark index selected (if applicable) to comply with a regulation that requires the Fund's primary benchmark to represent the overall applicable market.

⁴ Characteristics Definitions:

Average duration is a measure of the sensitivity of the price (the value of principal) of a fixed income investment to a change in interest rates. Duration is expressed as a number of years. Rising interest rates mean falling bond prices, while declining interest rates mean rising bond prices. Average Effective Maturity is a measure of sensitivity to liquidity and/or credit risk. Average effective maturity takes into account all call options exercised by the issuer as well as permissible maturity shortening devices such as demand features. Average effective maturity is computed using the nearest call date or maturity, whichever comes first. Yield to Maturity is the expected total return of a bond if held to maturity, accounting for the bond’s present value and future coupon payments. A bond's Average price is calculated by adding its face value to the price paid for it and dividing the sum by two. The average price is sometimes used in determining a bond's yield to maturity where the average price replaces the purchase price in the yield to maturity calculation. Distribution Yield is the annual yield an investor would receive if the most recent fund distribution remained the same going forward. The distribution yield is calculated by dividing the normalized current distribution (annualized) by the fund NAV per share.

Credit ratings are categorized using S&P. Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer's creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P's measures. Ratings of BBB or higher by S&P are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency's analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer's current financial condition and does not necessarily reflect its assessment of the volatility of a security's market value or of the liquidity of an investment in the security. Holdings designated as "Not Rated" are not rated by S&P.

Risk Considerations: 

There is no assurance that a portfolio will achieve its investment objective. Portfolios are subject to market risk, which is the possibility that the market values of securities owned by the portfolio will decline. Market values can change daily due to economic and other events (e.g. natural disasters, health crises, terrorism, conflicts and social unrest) that affect markets, countries, companies or governments. It is difficult to predict the timing, duration, and potential adverse effects (e.g. portfolio liquidity) of events. Accordingly, you can lose money investing in this portfolio. Please be aware that this portfolio may be subject to certain additional risks. Loans are generally associated with fixed income securities risk and are traded in a private, unregulated inter-dealer or inter-bank resale market and are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund's ability to buy or sell loans (thus affecting their liquidity) and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle; therefore the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders to meet short-term liquidity needs. Loans to entities located outside of the U.S. may have substantially different lender protections and covenants as compared to loans to U.S. entities and may involve greater risks. Loans may be structured such that they are not securities under securities law, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. Loans are also subject to risks associated with other types of income investments. Fixed-income securities are subject to the ability of an issuer to make timely principal and interest payments (credit risk), changes in interest rates (interest-rate risk), the creditworthiness of the issuer and general market liquidity (market risk). In a rising interest-rate environment, bond prices may fall and may result in periods of volatility and increased portfolio redemptions. In a declining interest-rate environment, the portfolio may generate less income. In addition to fixed income securities risk, asset-backed securities are subject to the risk that various federal and state consumer laws and other legal and economic factors may result in the collateral backing the securities being insufficient to support payment on the securities. Some also entail prepayment risk and extension risk, and may become more volatile in certain interest rate environment. Collateralized loan obligations carry additional risks such as the Fund may invest in CLOs that are subordinate to other classes and the complex structure may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. Distressed and defaulted securities are speculative and involve substantial risks in addition to the risks of investing in high yield securities, which are lower rated securities that may have a higher degree of credit and liquidity risk. The Fund will generally not receive interest payments on the distressed securities and the repayment of principal may also be at risk. These securities may present a substantial risk of default or may be in default at the time of investment, requiring the Fund to incur additional costs. Mezzanine investments are subordinated debt securities, thus they carry the risk that the issuer will not be able to meet its obligations and that the mezzanine investments may lose value. Investments in foreign markets entail special risks such as currency, political, economic, and market risks. The risks of investing in emerging market countries are greater than the risks generally associated with investments in foreign developed countries. Currency fluctuations could erase investment gains or add to investment losses. Illiquid securities may be more difficult to sell and value than publicly traded securities (liquidity risk). Derivative instruments may disproportionately increase losses and have a significant impact on performance. They also may be subject to counterparty, liquidity, valuation, correlation and market risks.  Portfolio Turnover. Consistent with its investment policies, the Fund will purchase and sell securities without regard to the effect on portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs. Active Management Risk. In pursuing the Portfolio’s investment objective, the Adviser has considerable leeway in deciding which investments to buy, hold or sell on a day-to-day basis, and which trading strategies to use. The success or failure of such decisions will affect performance. ETF Structure Risks. Authorized Participant Concentration Risk. The Portfolio has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. As a result, shares may trade at a discount to net asset value (“NAV”) and possibly face trading halts and/or delisting. Cash Transactions Risk. Unlike certain ETFs, the Fund may effect creations and redemptions in cash or partially in cash. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in shares may be less tax-efficient. Trading Risk. The market prices of Shares are expected to fluctuate, in some cases materially, in response to changes in the Portfolio's NAV, the intra-day value of holdings, and supply and demand for Shares. The Adviser cannot predict whether Shares will trade above, below or at their NAV. may pay significantly more or receive significantly less than the Fund’s NAV per share during periods when there is a significant premium or discount. Buying or selling Shares in the secondary market may require paying brokerage commissions or other charges imposed by brokers as determined by that broker. New Fund Risk. A new portfolio's performance may not represent how the portfolio is expected to or may perform in the long term. In addition, there is a limited operating history for investors to evaluate and the portfolio may not attract sufficient assets to achieve investment and trading efficiencies.
