Harbor Core Bond Fund (HCBRX)

Important 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.

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. There may be a greater risk that the Fund could lose money due to prepayment and extension risks because the Fund invests heavily at times in mortgage‑related and/or asset backed securities.

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

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.
