The Fund invests at least 80% of its total assets in securities that are included in the Index. The Index is designed to deliver exposure to equity securities of U.S. companies identified by Irrational Capital LLC (Irrational Capital or the Index Provider) as those it believes to possess strong corporate culture based on its proprietary scoring methodology . Companies with market capitalizations in excess of $1 billion at the time of Index reconstitution are eligible for inclusion in the Index. The Index is equally weighted and composed of approximately 70 to 100 companies with top Human Capital Factor scores at the time of Index reconstitution. The Index Provider 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 companys 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 the various characteristics varies with each reconstitution based on the most current data. The Index Provider expects to continue to refine its proprietary methods over time. The Index has been created and licensed to the Advisor by Irrational Capital and is calculated, published and distributed by Solactive AG (Solactive). The Index is comprised of equity securities traded on U.S. public securities exchanges. 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 concentrated in the group of industries comprising the information technology sector. Under normal circumstances, the Index is reconstituted annually and rebalanced quarterly. 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 in approximately the same proportion as represented in the Index itself. There also may be instances in which Harbor Capital Advisors, Inc. (the Advisor or Harbor Capital) 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. Show less
