Important Information

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. Large cap stocks may underperform compared to small or mid cap stocks, which may lead the Fund to lag behind funds focused on smaller caps, while mid cap stocks carry added risks like illiquidity and higher volatility than those of large companies. The Fund's investments in foreign securities expose it to higher risks than Funds investing only in the U.S., including currency risk, which may negatively impact its value if foreign currencies fluctuate against the U.S. dollar. There is no guarantee that the Subadvisor’s resource efficiency strategy will accurately provide exposure to resource efficient companies and the Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. The Subadvisor relies on company data for Resource Efficiency Scores but does not guarantee its accuracy or completeness. The Fund utilizes a quantitative model and there are limitations in every quantitative model. 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.

Diversification does not assure a profit or protect against loss in a declining market.
