Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

 

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

 

	Retirement Class	Institutional Class	Administrative Class	Investor Class
Management Fees	0.75%	0.75%	0.75%	0.75%
Distribution and Service (12b-1) Fees	None	None	0.25%	0.25%

Total Annual Fund Operating Expenses After Expense Reimbursement1	0.77%	0.85%	1.10%	1.21%

1  The Advisor has contractually agreed to limit the Fund’s operating expenses, excluding interest expense (if any) to 0.77% 0.85%, 1.10%, and 1.21% for the Retirement Class, Institutional Class, Administrative Class, and Investor Class, respectively, through February 29, 2024.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, under these assumptions, your costs would be: 

	One Year	Three Years	Five Years	Ten Years
Retirement	$79	$330	$601	$1,374
Institutional	$87	$355	$643	$1,466
Administrative	$112	$433	$776	$1,746
Investor	$123	$467	$834	$1,867

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares of the Fund are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Expense Example, do affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 100%.

Principal Investment Strategy

Under normal market conditions, the Fund invests at least 80% of its assets in a diversified portfolio of non-U.S. equity securities. The Fund invests primarily in the stocks of foreign companies located in developed markets, but it may also invest up to 15% of its assets in the securities of companies located in emerging markets. The Fund invests in stocks across the market capitalization spectrum.

The Subadvisor manages the Fund using an active, quantitative investment strategy. In selecting investments for the Fund, the Subadvisor forecasts expected returns for global equity markets and individual securities using a range of quantitative factors, including:

◾

Valuation

◾

Earnings

◾

Quality

◾

Price patterns

◾

Economic data

◾

Risk

The Subadvisor emphasizes those factors that it believes to have proven most effective in predicting returns.

In constructing the Fund’s portfolio, the Subadvisor considers the company, country, and industry weightings of the Fund’s benchmark index, the MSCI EAFE Index, as well as the portfolio’s level of risk, estimated transaction costs, liquidity, and other considerations. In making buy and sell decisions, the Subadvisor analyzes the risk and expected return characteristics of the portfolio’s current holdings as compared to the entire universe of companies. The Subadvisor also considers companies’ environmental, social and governance (“ESG”) initiatives that it believes may have a material impact on an issuer and the value of its securities. The Subadvisor engages with company management and seeks to identify inconsistencies between stated positions and actions.

The Subadvisor purchases securities that in its view have higher risk-adjusted expected returns and sells securities that in its view have lower risk-adjusted expected returns, provided that the costs of implementing the purchases and sales of such securities do not exceed the expected value added to the portfolio of such investment decisions, as determined by the Subadvisor. Throughout this process, the Subadvisor utilizes proprietary quantitative models

1

Summary Prospectus
Harbor International Core Fund (formerly, Harbor Overseas Fund)

to make its assessments and, except in very limited circumstances, follows the output of those models when making buy and sell decisions for the Fund’s portfolio.

The equity securities in which the Fund invests include common stocks as well as preferred securities and securities issued by real estate investment trusts (REITs). The Fund may also purchase American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts (GDRs), and other similar depositary receipts, which are certificates typically issued by a bank or trust company that represent ownership interests in securities issued by a foreign or domestic company. The Fund may invest in securities denominated in, and/or receiving revenues in, foreign currencies.

Principal Risks

There is no guarantee that the investment objective of the Fund will be achieved. Stocks fluctuate in price and the value of your investment in the Fund may go down. This means that you could lose money on your investment in the Fund or the Fund may not perform as well as other investment options. Principal risks impacting the Fund (in alphabetical order after the first four risks) include:

Foreign Securities Risk: An investment in the Fund 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 governmental bodies of other countries and less stringent investor protection and disclosure standards of foreign markets. Foreign securities are sometimes less liquid and harder to value than securities of U.S. issuers. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. If foreign securities are denominated and traded in a foreign currency, the value of the Fund’s foreign holdings can be affected by currency exchange rates and exchange control regulations. The Fund’s investments in foreign securities may also be subject to foreign withholding taxes.

Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Model Risk: 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. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, historical trends in data may not be predictive going forward. The strategies and techniques employed in a quantitative model cannot fully match the complexity of the financial markets and therefore sudden unanticipated changes in underlying market conditions can significantly impact their performance. The effectiveness of the given strategy or technique may deteriorate in an unpredictable fashion for any number of reasons including, but not limited to, an increase in the amount of assets managed or the use of similar strategies or techniques by other market participants and/or market dynamic shifts over time. In addition, factors that affect a security’s value can change over time, and these changes may not be reflected in the quantitative model. Any model may contain flaws the existence and effect of which may be discovered only after the fact or not at all. There can be no assurances that the strategies pursued or the techniques

implemented in the quantitative model will be profitable, and various market conditions may be materially less favorable to certain strategies than others. Even in the absence of flaws, a model may not perform as anticipated.

Equity Risk: The values of equity or equity-related securities may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than fixed income securities.

Market Risk: Securities markets are volatile and can decline significantly in response to adverse market, economic, political, regulatory or other developments, which may lower the value of securities held by the Fund, sometimes rapidly or unpredictably. Events such as war, acts of terrorism, social unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, sanctions, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.

Depositary Receipts Risk: Depositary receipts are certificates evidencing ownership of shares of a foreign issuer. These certificates are issued by depository banks and generally trade on an established market in the U.S. or elsewhere. The underlying shares are held in trust by a custodian bank or similar financial institution. The depository bank may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding dividends and interest and corporate actions. Depositary receipts are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. Depositary receipts are subject to the risks associated with investing directly in foreign securities.

Emerging Market Risk: Foreign securities risks are more significant in emerging market countries. These countries may have relatively unstable governments and less-established market economies than developed countries. Emerging markets may face greater social, economic, regulatory and political uncertainties. These risks make emerging market securities more volatile and less liquid than securities issued in more developed countries. Securities exchanges in emerging markets may suspend listed securities from trading for substantially longer periods of time than exchanges in developed markets, including for periods of a year or longer. If the Fund is holding a suspended security, that security would become completely illiquid as the Fund would not be able to dispose of the security until the suspension is lifted. In such instances, it can also be difficult to determine an appropriate valuation for the security because of a lack of trading and uncertainty as to when trading may resume.

ESG Factors Risk: The consideration of ESG factors by the Subadvisor and/or Advisor, as applicable, could cause the Fund to perform differently than other funds. ESG factors are not the only consideration used by the Subadvisor and/or Advisor, as applicable, in making investment decisions for the Fund and the Fund may invest in a company that scores poorly on ESG factors if it scores well on other criteria. ESG factors may not be considered for every investment decision.

Foreign Currency Risk: As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the

2

Summary Prospectus
Harbor International Core Fund (formerly, Harbor Overseas Fund)

U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected.

Geographic Focus Risk: The Fund may invest a substantial amount of its assets in securities of issuers located in a single country or geographic region. As a result, any changes to the regulatory, political, social or economic conditions in such country or geographic region will generally have greater impact on the Fund than such changes would have on a more geographically diversified fund and may result in increased volatility and greater losses.

Issuer Risk: An adverse event affecting a particular issuer in which the Fund is invested, such as an unfavorable earnings report, may depress the value of that issuer’s stock, sometimes rapidly or unpredictably.

Preferred Stock Risk: Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities.

REIT Risk: Investing in REITs will subject the Fund to additional risks.  The REITs in which the Fund invests may decline in value as a result of factors affecting the real estate sector, such as changes in real estate values, changes in property taxes and government regulation affecting zoning, land use and rents, changes in interest rates, changes in the cash flow of underlying real estate assets, levels of occupancy, and market conditions, as well as the management skill and creditworthiness of the issuer.  Investments in REITs are also subject to additional risks, including the risk that REITs are unable to generate cash flow to make distributions to unitholders and fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended.

Selection Risk: The Subadvisor’s judgment about the attractiveness, value and growth potential of a particular security may be incorrect.  The Subadvisor and/or Advisor, as applicable, potentially will be prevented from executing investment decisions at an advantageous time or price as a result of domestic or global market disruptions, particularly disruptions causing heightened market volatility and reduced market liquidity, as well as increased or changing regulations.  Thus, investments that the Subadvisor and/or Advisor, as applicable, believes represent an attractive opportunity or in which the Fund seeks to obtain exposure may be unavailable entirely or in the specific quantities or prices sought by the Subadvisor and/or Advisor, as applicable, and the Fund may need to obtain the exposure through less advantageous or indirect investments or forgo the investment at the time.

Small and Mid Cap Risk: The Fund’s performance may be more volatile because it may invest in issuers that are smaller companies. Smaller companies may have limited product lines, markets and financial resources. Securities of smaller companies are usually less stable in price and less liquid than those of larger, more established companies. Additionally, small and mid cap stocks may fall out of favor relative to large cap stocks, which may cause the Fund to underperform other equity funds that focus on large cap stocks.
