The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 20% of total assets may be invested in securities below investment grade (also known as junk bonds). A “junk bond” is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called “high yield bonds” and “non‑investment grade bonds.” These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody’s). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security’s quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.
