Strategy. The Fund invests at least 80% of its total assets in the securities of the Indxx Renewable Energy Producers Index (the "Underlying Index") and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Fund may lend securities representing up to one-third of the value of the Funds total assets (including the value of the collateral received).

The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Fund may lend securities representing up to one-third of the value of the Funds total assets (including the value of the collateral received). The Underlying Index is designed to provide exposure to publicly traded companies that produce energy from renewable sources including wind, solar, hydroelectric, geothermal, and biofuels (including publicly traded companies that are formed to own operating assets that produce defined cash flows (YieldCos)) (collectively, "Renewable Energy Companies"), as defined by Indxx LLC, the provider of the Underlying Index (the "Index Provider"). In constructing the Underlying Index, the Index Provider first identifies FactSet Industries related to renewable energy production. Companies within these industries, as of the selection date, are further reviewed by the Index Provider on the basis of revenue related to renewable energy production. To be eligible for the Underlying Index, a company is considered by the Index Provider to be a Renewable Energy Company if the company generates at least 50% of its revenues from renewable energy production, as determined by the Index Provider. The Index Provider classifies Renewable Energy Companies as those companies that produce energy from renewable sources, including: wind, solar, hydroelectric, geothermal, and biofuels (including YieldCos), as determined by the Index Provider. The Underlying Index is weighted according to a modified capitalization weighting methodology and is reconstituted and re-weighted semi-annually. Modified capitalization weighting seeks to weight constituents primarily based on market capitalization, but subject to caps on the weights of the individual securities. Generally speaking, this approach will limit the amount of concentration in the largest market capitalization companies and increase company-level diversification. The Underlying Index may include large-, mid- or small-capitalization companies, and components may include, but are not limited to, utilities, industrials and energy companies. The Fund's investment objective and Underlying Index may be changed without shareholder approval. The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of, and unaffiliated with, the Fund and Global X Management Company LLC, the investment adviser for the Fund (the "Adviser"). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Adviser uses an indexing approach to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to "outperform" the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index. The Adviser expects that, over time, the correlation between the Fund's performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy. The Fund concentrates its investments (i.e . , holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2025, the Underlying Index was concentrated in the independent power and renewable energy industry and had significant exposure to the utilities sector. The Fund is classified as non-diversified, which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. Show less
