This information should not be considered as a recommendation to purchase or sell a particular security. The holdings mentioned may change at any time and may not represent current or future investments. There is no guarantee that the investment objective of the Fund will be achieved. Fixed income investments are affected by interest rate changes and the creditworthiness of the issues held by the Fund. As interest rates rise, the values of fixed income securities held by the Fund are likely to decrease and reduce the value of the Fund's portfolio. High-yield investing poses additional credit risk related to lower-rated bonds.

Investors should carefully consider the investment objectives, risks, charges and expenses of a Harbor fund before investing. To obtain a summary prospectus or prospectus for this and other information, visit harborfunds.com or call 800-422-1050. Read it carefully before investing.
