Performance data shown represents past performance and is no guarantee of future results. Fund 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 Russell 2000® Growth Index is an unmanaged index representing the smallest 2000 stocks with the highest price‑to‑book ratio and future earnings. This unmanaged index does not reflect fees and expenses and is not available for direct investment. The Russell 2000® Growth Index and Russell® are trademarks of Frank Russell Company.

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. Stock markets are volatile and equity values can decline significantly in response to adverse issuer, political, regulatory, market and economic conditions. Stocks of small cap companies pose special risks, including possible illiquidity and greater price volatility than stocks of larger, more established companies.

Weighted Average Market Capitalization: The average size of the companies in a portfolio or index as measured by the market value of outstanding shares.

Price/Book: The price‑to‑book (P/B) ratio evaluates a firm's market value relative to its book value.

Adjusted Trailing P/E Ratio: The Adjusted Trailing P/E (Price/Earnings) Ratio is the closing stock price divided by the sum of the last 12 months actual EPS.

% EPS Growth – Past 3 year: Earnings per share refers to the bottom‑line measure of a company’s profitability defined as net income divided by the number of outstanding shares.

Return on Equity: Return on equity (ROE) is a measure of financial performance calculated by dividing net income by shareholders' equity.

Forecasted P/E Ratio: a measure of the P/E (price‑to‑earnings) ratio using forecasted earnings for the P/E calculation.

Alpha is the risk‑adjusted excess return of an investment relative to the return of a benchmark index.

Beta measures the relative volatility of an investment, as an indication of its relative risk.

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.
