Loomis Sayles Instl High Income (Loomis Sayles Institutional Hig) Fonds

The fund will invest primarily in below investment-grade fixed-income securities (commonly known as "junk bonds") and other securities that are expected to produce a relatively high level of income (including income-producing preferred stocks and common stocks). The fund's fixed-income securities investments may include unrated securities (securities that are not rated by a rating agency) if Loomis Sayles determines that the securities are of comparable quality to rated securities that the fund may purchase.
