Climate-friendly investing for all

We don’t invest in fossil fuels
The fossil fuel sector has had the worst returns and has been the most volatile of the US economy for the past two decades. We let you invest in a diverse set of industries without forcing you to invest in this sector.

We vote for the planet
We pool investors' shares to vote in favor of climate-related shareholder proposals at the companies it invests in. This can set up some of the biggest companies in the world for success in a changing world.

RISKS AND DISCLOSURE
As with all investments, there are risks involved with investing in the Sphere 500. Climate Investing Consideration Risk-Considerations related to climate risk, such as environmental criteria (e.g., fossil fuel screens), applied to the Index’s construction may limit the number of investment opportunities available to the Fund, and as a result, at times, the Fund may underperform funds that are not subject to similar investment restrictions. For example, the Index may exclude certain securities due to climate-focused considerations when other investment considerations would suggest that investing in such securities would be advantageous. The Fund may also underperform funds that invest in the energy and utilities sectors, particularly in times of rising oil, gas and energy prices. Other risks include, but are not limited to general market risk, small fund risk, large cap risk, common stock risk, sector risk, industry concentration risk, passive investment risk, index calculation risk, limited operating history risk, cybersecurity risk, tracking error risk, operation risk, and third-party data risks as it relates to the composition of the Index. For a detailed explanation of the risks associated with the Sphere 500 and the underlying Index, please read the prospectus.
The Sphere 500 Climate Fund tracks the Sphere 500 Fossil-Free Index (SPFFXI). The Index is constructed beginning with the largest 500 U.S. companies that trade on regulated U.S. exchanges by market capitalization. The index administrator, BITA GmbH, then eliminates companies from this investable universe using data obtained from As You Sow, an unaffiliated non-profit organization that promotes environmental responsibility through shareholder advocacy. As You Sow eliminates companies from the Index based primarily on their risk profile of being exposed to the fossil fuel industry and secondarily, by other exclusionary screens, including companies engaged in deforestation activities, civilian and military firearms manufacturing and related guns/arms sales, prison and border security operations, and tobacco and e-cigarette manufacturing. The elimination of these companies from the Index is intended to foster and support the climate-focused, social investing goals of the Fund. The fund may invest in companies that use fossil fuels as a part of their business or have used fossil fuels in the past. Investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Index returns do not reflect the effects of fees or expenses. It is not possible to invest directly in an index.
