The index is composed of large- and mid-cap developed market equities, excluding the U.S., that are selected and weighted so that, in the aggregate, the portfolio is compatible with the objectives of the Paris Agreement by following a decarbonization trajectory, reducing exposure to climate-related transition and physical risks and increasing exposure to companies favorably positioned for the transition to a low-carbon economy. The fund generally will invest at least 90% of its assets in the component securities of its index.
