Research Suggests That Doing the Right Thing Pays.

The Fund employs an indexing investment approach designed to track the performance of the Human Capital Factor Unconstrained Index (“The Index”). 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 large cap U.S. companies that demonstrate high employee engagement, based on scores produced by Irrational Capital LLC (“Irrational Capital” or the “Index Provider”). Large cap companies are defined by the Fund as those with market capitalizations over $1 billion at the time of Index reconstitution. 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.

Investing involves risk, principal loss is possible. Unlike mutual funds, ETFs may trade at a premium or discount to their net asset value. Harbor ETFs are new and have limited operating history to judge.

Shares are bought and sold at market price not net asset value (NAV). Market price returns are based upon the closing composite market price and do not represent the returns you would receive if you traded shares at other times.

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. The Fund may not exactly track the performance of the Index with perfect accuracy at all times. Tracking error may occur because of pricing differences, timing and costs incurred by the fund or during times of heightened market volatility. The Fund relies on the Index provider's methodology in assessing whether a company may be considered a corporate culture leader. There is no guarantee that the construction methodology will accurately assess a company to include or exclude it from the index which could have an adverse effect on the Fund's returns. The Fund's assets may be concentrated in a particular sector or industries to the extent the Index is concentrated and is subject to the risk that economic, political, or other market conditions that have a negative effect on that sector or industry will negatively impact the value of the Fund.
