Description

Fund Objective
The fund's primary objective is to provide a high level of current income. Its secondary objective is capital appreciation.
Distinguishing Characteristics
An income-oriented strategy that invests in a broad range of traditional, high-income asset classes. The fund is designed to provide less volatility and equity correlation than a standalone high yield or emerging market debt fund, without meaningfully reducing income. With a focus on fundamental analysis coupled with a rigorous relative value approach to sector allocation, the fund aims to generate high income across market cycles.
Types of Investments
Primarily invests in a broad range of debt securities across the credit spectrum, including high-yield and investment-grade corporate, emerging market, and securitized debt. The fund may opportunistically invest in other sectors, including U.S. government debt, municipal debt and non-corporate credit.
Holdings Outside the U.S.
The fund may invest a significant portion of its assets in securities of issuers domiciled outside the United States.
Maturity
The fund invests in debt securities with a wide range of maturities.
Portfolio Restrictions
The fund may invest substantially in securities rated Ba1 or below and BB+ or below, or in securities that are unrated but determined to be of equivalent quality by the fund’s investment adviser. The fund may invest in certain derivative instruments, such as futures contracts and swaps. The fund may invest in a derivative if, in the opinion of the investment adviser, the expected risks and rewards of the proposed investment are consistent with the investment objective and strategies of the fund.
