Effective on February 2, 2022, Income Research + Management (“IR+M”) replaced Pacific Investment Management Company, LLC (“PIMCO”) as investment subadviser to Harbor Bond Fund (the “Fund”). In connection with this change, the Fund was renamed “Harbor Core Plus Fund” and its investment strategy changed to reflect IR+M’s approach to managing the Fund’s assets. Performance prior to that date is not attributable to IR+M.

Performance data shown represents past performance and is no guarantee of future results. Past performance is net of management fees and expenses and reflects reinvested dividends and distributions. Past performance reflects the beneficial effect of any expense waivers or reimbursements, without which returns would have been lower. Investment returns and principal value will fluctuate and when redeemed may be worth more or less than their original cost. Returns for periods less than one year are not annualized. Current performance may be higher or lower and is available through the most recent month end at harborcapital.com or by calling 800-422-1050.

The Bloomberg US Aggregate Bond Index is an unmanaged index of investment-grade fixed-rate debt issues with maturities of at least one year. This unmanaged index does not reflect fees and expenses and is not available for direct investment.
