Investment Objective

The Fund seeks to provide investment results that correspond, before fees and expenses, to the performance of the Human Capital Factor Small Cap Index (the “Index”).

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)

 

Management Fees	0.60%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses1,2	0.00%
Acquired Fund Fees and Expenses2	0.04%
Total Annual Fund Operating Expenses	0.64%

1  Pursuant to the Investment Advisory Agreement, the Advisor pays all of the operating expenses of the Fund, except for (i) the fee payment under the Investment Advisory Agreement; (ii) payments under the Fund’s 12b-1 plan (if any); (iii) the costs of borrowing, including interest and dividend expenses; (iv) taxes and governmental fees; (v) acquired fund fees and expenses; (vi) brokers’ commissions and any other transaction-related expenses and fees arising out of transactions effected on behalf of the Fund; (vii) costs of holding shareholder meetings; and (viii) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the Fund’s business.

2  “Other Expenses” and “Acquired Fund Fees and Expenses” are estimated for the current fiscal year.

 

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other exchange-traded 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
$65	$205

 

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. The Fund had not commenced operations as of the date of this Prospectus and no portfolio turnover rate existed at the time of this publication.

Principal Investment Strategy

The Fund employs an indexing investment approach designed to track the performance of the Index. The Fund invests at least 80% of its total assets in securities that are included in the Index.

The Index consists of a modified market capitalization-weighted portfolio of equity securities of approximately 200 small cap U.S. companies identified by Irrational Capital LLC (“Irrational Capital” or “IC”) as those it believes to possess strong corporate culture based on its proprietary scoring methodology. The Index was developed by the Canadian Imperial Bank of Commerce (the “Index Provider” or “CIBC”).

Irrational Capital calculates Human Capital Factor scores based on a proprietary, rules-based scoring methodology it developed by leveraging its research in behavioral science, data science and human capital. The scoring methodology seeks to quantitatively measure the contribution of a company’s corporate culture to its financial performance. Irrational Capital calculates Human Capital Factor scores based on a combination of multiple characteristics, such as

◾

Employee engagement and motivation

◾

Trust and transparency

◾

Point of view diversity

◾

Compensation fairness

The significance of each characteristic to the calculation of the Human Capital Factor scores varies at the time of each calculation based on the most recent data obtained by Irrational Capital. Irrational Capital expects to continue to refine its proprietary methods over time.

Constituents of the Solactive GBS United States 2000 Index, which intends to track the performance of the companies ranked 1001 to 3000 in the U.S. stock market based on free float market capitalization (the “index universe”), at the time of Index reconstitution are eligible for inclusion in the Index. As of February 28, 2023, the range of the index universe was approximately $4.5 million to $6.0 billion. The top-ranking companies in the index universe (based on the most recent annual scores calculated by Irrational Capital as of each reconstitution) will be included in the Index. Index constituents in the same sector are weighted based on their float-adjusted market capitalizations, subject to certain caps on individual stock weights. On reconstitution dates, the Index will target the same sector weights as the index universe. If after the Index’s weighting and capping rules are applied, a sector’s weight in the Index would be less than its weight in the index universe, the Index will include exchange-traded funds that invest specifically in small cap stocks and securities of the corresponding sector (known as sector ETFs), or such other sector proxy as the Index Provider may determine, to fill the remaining

weight and ensure sector neutrality as compared with the index universe on the reconstitution date.

The Index has been created and licensed to Harbor Capital Advisors, Inc. (the “Advisor or “Harbor Capital”) by the Index Provider and is calculated, published and distributed by Solactive AG (“Solactive”). The Index is comprised of equity securities traded on U.S. public securities exchanges as well as sector ETFs. The Fund may purchase American Depositary Receipts (ADRs), 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 concentrate its investments in a particular sector, industry or group of industries from time to time to the extent that the Index concentrates in a sector, industry or group of industries. As of the date of this Prospectus, the Index is not concentrated in any particular sector. Under normal circumstances, the Index is reconstituted annually.

The Fund uses an indexing investment approach to attempt to approximate, before fees and expenses, the investment performance of the Index. The Fund generally will use a replication strategy, which means that the Fund seeks to hold each security found in the Index (including shares of sector ETFs included in the Index) in approximately the same proportion as represented in the Index itself. There also may be instances in which the Advisor may choose to underweight or overweight a security in the Index, purchase securities not in the Index that the Advisor believes are appropriate to substitute for certain securities in the Index or utilize various combinations of other available investment techniques in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index. The Fund does not take temporary defensive positions when markets decline or appear overvalued.

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 nine risks) include:

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.

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.

Small Cap Risk: The Fund’s performance may be more volatile because it invests primarily 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 cap stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks.

Index Tracking Risk: The Fund is not expected to track the performance of the Index at all times with perfect accuracy. The Fund’s return may not track the performance of the Index for a number of reasons. For example, tracking error may occur because of differences between the securities held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), transaction costs incurred by the Fund, or the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest. Any transaction costs and market exposure arising from rebalancing the Fund’s portfolio to reflect changes in the composition of the Index will be borne directly by the Fund and its shareholders. The Fund may not be able to invest in certain securities included in the Index or may not be able to invest in them in the exact proportions in which they are represented in the Index, due to legal restrictions, potential adverse tax consequences or other regulatory reasons. The risk that the Fund may not track the performance of the Index may be magnified during times of heightened market volatility or other unusual market conditions. For tax efficiency purposes, the Fund may sell certain securities to realize losses causing it to deviate from the Index.

Index Strategy Risk: The Fund is managed to seek to track, before fees and expenses, the performance of the Index. Therefore, unless a specific security is removed from the Index because it no longer qualifies to be included in the Index, the Fund generally would not sell a security because the security’s issuer is in financial trouble. If a specific security is removed from the Index, it is possible that the Fund may be forced to sell such security at an inopportune time or for prices other than at current market values, which could have a negative effect on the Fund’s performance.  As a result, the Advisor will not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. Thus, based on market and economic conditions, the Fund’s performance could be lower than funds that actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more securities.

Index Construction Risk: The Index Provider selects companies for the Index based on a proprietary methodology. The theories upon which the Index Provider bases the Index and/or Irrational Capital bases the methodology used in scoring companies for the Index may be unsound. The Index Provider and Irrational Capital rely on third-party data they believe to be reliable in constructing the Index and scoring companies, but neither guarantees the accuracy or availability of any such third-party data, and there is also no guarantee with respect to the accuracy, availability or timeliness of the production of the Index. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Companies will be excluded from the Index if sufficient data is not available to produce a score, which may result in the exclusion of companies that could otherwise be considered to have strong corporate culture. The Index Provider’s assessment of a company may differ from that of another investor

or investment manager. Errors in the construction or calculation of the Index may occur from time to time and any such errors may not be immediately identified and corrected, which may have an adverse impact on the Fund and its shareholders. There is no guarantee that the construction methodology will accurately provide exposure to strong corporate culture. The use of sector ETFs or other sector proxies to maintain sector neutrality may result in indirect exposure to companies that do not have strong corporate culture and would not otherwise be included in the Index.

Data Risk: The Index Provider relies heavily on information and data provided by third-parties, including the list of high scoring companies provided by Irrational Capital and used to select companies for the Index. Such third-party data includes information derived from survey data. There is no guarantee that survey data will be accurate, complete or representative of a company’s status with respect to its corporate culture. Survey data may be subject to certain biases, including response bias and non-response bias. Furthermore, information derived from survey data may not reflect the most current status of a company, and a company’s financial results may deteriorate prior to a corresponding decline in survey data results. Because the Index is reconstituted only annually, there could be a significant delay before a company’s current status is reflected in the Index. If survey data is unreliable or outdated, the Index may not be successful in providing the specified exposure. Additionally, survey data collected from small cap companies may be more limited than data collected from large or mid cap companies. Third-party data providers' coverage of small cap companies is generally less extensive than that of large or mid cap companies with respect to corporate culture data. As a result, Irrational Capital may rely more heavily on publicly available data to calculate scores for small cap companies. Publicly available data may be more limited or of less uniform quality than survey data.

Authorized Participant Concentration/Trading Risk: Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for shares, and shares may be more likely to trade at a premium or discount to the Fund’s net asset value and to face trading halts and/or delisting. This risk may be heightened during periods of volatility or market disruptions.

Premium/Discount Risk: The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. The Advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. This may

result in the Fund’s shares trading significantly above (premium) or below (discount) the Fund’s net asset value, which will be reflected in the intraday bid/ask spreads and/or the closing price of shares as compared to net asst value. However, given that shares can be purchased and redeemed in Creation Units to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

Cash Transactions Risk: The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects all of its creations and redemptions in-kind. Because the Fund may effect redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of portfolio securities may result in capital gains or losses and may also result in higher brokerage costs. To the extent costs are not offset by transaction fees charged by the Fund to APs, the costs of cash transactions will be borne by the Fund.

Concentration Risk: The Fund’s assets may be concentrated in a particular sector, industry or group of industries to the extent the Index is so concentrated. Concentration of the Fund’s assets in a particular sector, industry or group of industries will subject the Fund to the risk that economic, political or other conditions that have a negative effect on that sector, industry or group of industries will negatively impact the Fund to a greater extent than if the Fund’s assets were concentrated in a wider variety of sectors or industries.

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, which 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.

Investment in Other Investment Companies Risk: Investments in other investment companies (including money market funds) are subject to market and selection risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund and, indirectly, the expenses of the investment companies. In addition to these risks, a sector ETF may fail to accurately track the market segment or index that underlies its investment objective and the market price of the underlying ETF’s shares may trade at a premium or a discount to their net asset value.

Issuer Risk: An adverse event affecting a particular issuer in which the Fund is invested, such as an unfavorable earnings report, may

3

Harbor Corporate Culture Small Cap ETF

depress the value of that issuer’s stock, sometimes rapidly or unpredictably.

New Fund Risk: There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. The Board of Trustees may liquidate the Fund at any time in accordance with the Declaration of Trust and governing law. As a result, the timing of the Fund’s liquidation may not be favorable.

Buying and Selling Fund Shares

Individual Fund shares may only be bought and sold in the secondary market through a broker or dealer at a market price. Shares of the Fund are listed and traded on an exchange at market price throughout the day rather than at NAV and may trade at a price greater than the Fund’s NAV (premium) or less than the Fund’s NAV (discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling Fund shares in the secondary market (the “bid-ask spread”). Recent information, including information regarding the Fund’s NAV, market price, premiums and discounts, and bid-ask spread, is available at harborcapital.com.

Tax Information

Distributions you receive from the Fund are subject to federal income tax and may also be subject to state and local taxes. These distributions will generally be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred retirement account, such as a 401(k) plan or individual retirement account. Investments in tax-deferred accounts may be subject to tax when they are withdrawn.

Payments to Broker-Dealers and Other Financial Intermediaries

The Advisor and/or its related companies have in the past and could in the future pay intermediaries, which may include banks, broker-dealers, or financial professionals, for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems and data or other services related to the sale of Fund shares and related services. These payments create a conflict of interest by influencing the broker-dealer or other intermediary and your sales representative to recommend the Fund over another investment. Ask your sales representative or visit your financial intermediary’s website for more information.
