The Underlying Index is designed to reflect the performance of a selection of companies that exhibit certain environmental, social and governance (ESG) characteristics, while also seeking to provide broad-market, core exposure to publicly traded equity securities issued by companies domiciled in developed market countries, excluding the U.S. The Underlying Index is designed to minimize tracking differences relative to the Northern Trust Developed Markets ex US Large Cap Index, (the Parent Index), while also seeking (a) an aggregate higher scoring of certain ESG characteristics, as measured by the Northern Trust ESG Vector Score (ESG Vector Score) described below, and (b) reduction of aggregate climate-related risk, as measured by certain carbon-related risk metrics, each relative to the Parent Index. The Underlying Index also excludes certain companies by using controversial business involvement and norms-based screens.
