Important Information

Effective February 3, 2026, the name of the fund’s subadvisor changed from BlueCove Limited to Ares Systematic Credit Limited. Effective March 1, 2026, the name of Harbor Convertibles Securities Fund changed to Harbor Ares Systematic Convertible Securities Fund. These changes do not affect the fund’s investment objective, strategies, risks, fees, or portfolio management. 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.

Ares Systematic Credit defines "scientific investing" as the structured investment process based on the testing of investment hypotheses using historical data, which utilizes proprietary quantitative models to produce investment recommendations as described in the Fund's Prospectus. Ares Systematic Credit's portfolio management team retains discretion with respect to all investment decisions.

The Morningstar Medalist Ratings are shown for funds that have received a rating of Gold, Silver, or Bronze The funds shown without Medalist Ratings may not have received a Medalist Rating or may have received lower ratings.

The Morningstar Medalist Rating™ is the summary expression of Morningstar’s forward‑looking analysis of investment strategies as offered via specific vehicles using a rating scale of Gold, Silver, Bronze, Neutral, and Negative. The Medalist Ratings indicate which investments Morningstar believes are likely to outperform a relevant index or peer group average on a risk‑adjusted basis over time. Investment products are evaluated on three key pillars (People, Parent, and Process) which, when coupled with a fee assessment, forms the basis for Morningstar’s conviction in those products’ investment merits and determines the Medalist Rating they’re assigned. Pillar ratings take the form of Low, Below Average, Average, Above Average, and High. Pillars may be evaluated via an analyst’s qualitative assessment (either directly to a vehicle the analyst covers or indirectly when the pillar ratings of a covered vehicle are mapped to a related uncovered vehicle) or using algorithmic techniques. Vehicles are sorted by their expected performance into rating groups defined by their Morningstar Category and their active or passive status. When analysts directly cover a vehicle, they assign the three pillar ratings based on their qualitative assessment, subject to the oversight of the Analyst Rating Committee, and monitor and reevaluate them at least every 14 months. When the vehicles are covered either indirectly by analysts or by algorithm, the ratings are assigned monthly. For more detailed information about these ratings, including their methodology, please go to global.morningstar.com/managerdisclosures/.

The Morningstar Medalist Ratings are not statements of fact, nor are they credit or risk ratings. The Morningstar Medalist Rating (i) should not be used as the sole basis in evaluating an investment product, (ii) involves unknown risks and uncertainties which may cause expectations not to occur or to differ significantly from what was expected, (iii) are not guaranteed to be based on complete or accurate assumptions or models when determined algorithmically, (iv) involve the risk that the return target will not be met due to such things as unforeseen changes in management, technology, economic development, interest rate development, operating and/or material costs, competitive pressure, supervisory law, exchange rate, tax rates, exchange rate changes, and/or changes in political and social conditions, and (v) should not be considered an offer or solicitation to buy or sell the investment product. A change in the fundamental factors underlying the Morningstar Medalist Rating can mean that the rating is subsequently no longer accurate.
