Effective on March 1, 2023, BlueCove Limited became investment subadviser to Harbor Convertible Securities Fund. In connection with this change, the Fund’s investment strategy and risk changed to reflect BlueCove’s approach to managing the Fund’s assets. Please see the Fund's Prospectus for additional information.

From time to time, certain fees and/or expenses have been voluntarily or contractually waived or reimbursed, which has resulted in higher returns. Without these waivers or reimbursements, the returns would have been lower. Voluntary waivers or reimbursements may be applied or discontinued at any time without notice. Only the Board of Trustees may modify or terminate contractual fee waivers or expense reimbursements.

As a result of changing market conditions, total net asset levels, expenses and other factors may change at any time during the current fiscal period and may differ from those shown.

All investments involve risk including the possible loss of principal. Fixed income securities fluctuate in price in response to various factors, including changes in interest rates, changes in market conditions and issuer-specific events, and the value of your investment in the Fund may go down. There is a greater risk that the Funds will lose money because they invest in below- investment grade fixed income securities and unrated securities of similar credit quality (commonly referred to as “high-yield securities” or “junk bonds”). These securities are considered speculative because they have a higher risk of issuer default, are subject to greater price volatility and may be illiquid. The market for convertible securities is less liquid than the market for non-convertible corporate bonds. There are limitations inherent in every quantitative model. The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments than the market as a whole or securities selected using only fundamental analysis. Because the Funds may invest in securities of foreign issuers, an investment in the Funds is subject to special risks in addition to those of U.S. securities. These risks include heightened political and economic risks, greater volatility, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, possible sanctions by government bodies of other countries and less stringent investor protection and disclosure standards of foreign markets.

Wtd. Avg. Market Coupon (%): the weighted average coupon rate of the underlying bonds in the Fund.

Wtd. Avg. Maturity (yrs): the weighted average length of time to the repayment of principal for the securities in the Fund. This metric considers the likelihood that bonds will be called or prepaid before the scheduled maturity date.

Wtd. Avg. Duration (yrs): the weight average duration of the underlying bonds or derivative market exposures in the Fund. Duration is a time measure of a bond's interest-rate sensitivity. The longer a fund's duration, the more sensitive the fund is to shifts in interest rates

Wtd. Avg. Convertible Price ($): the weighted average price of the underlying corporate securities in the Fund, usually preferred shares or bonds, that can be converted (exchanged) for a set number of other securities — usually common shares — at a given price.
