For the first time, divesting from fossil fuels is easy, accessible, and competitive.

Sphere helps the advisor community deliver on the demands of customers and plan participants by providing a climate-friendly and cost-effective US core equity investment option. A number of family offices and institutions have already exited the fossil fuel industry, often citing worrying economic factors and a need to protect long-term value as a driving force for decisions, including the Rockefeller Foundation, the New York State Pension Fund, and the Harvard Endowment.

This solution allows advisors and employers to demonstrate their commitment to fiduciary duty with a high-quality product at reasonable fees while satisfying a deeply personal desire of clients, without having to choose between the two. The Sphere 500 Fossil-Free Index tracks the Top 500 US companies by market capitalization and excludes fossil fuel companies to avoid stranded asset risk. The fund votes shares for the planet, not for the status quo.

The Sphere 500 Fossil-Free Index starts with the largest 500 U.S. companies by market capitalization and excludes companies defined by As You Sow, an unaffiliated non-profit, as being in the fossil fuel industry or engaged in deforestation activities, firearms manufacturing or gun sales, operating private prisons, or manufacturing tobacco products.  This index has climate-focused social goals and excludes those industries that are in decline over long-term timelines.

Fossil fuel companies are defined as those whose main lines of business are to produce, distribute, or refine fossil fuels, hold reserves of fossil fuels, utilities that are primarily fossil fuel-powered, and producers of equipment for any of the above.

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.

The performance data quoted represents past performance. Current performance may be lower or higher than the performance data quoted above. Past performance is no guarantee of future results.
