This fund aims to mirror the performance of a specific benchmark index. This underlying index is carefully constructed from a selection of companies that collectively demonstrate superior financial health and stability compared to the broader Northern Trust 1250 Index. The Northern Trust 1250 Index itself represents a diverse collection of large and medium-sized U.S. corporations, weighted by their publicly traded market value. To achieve its investment goal, the fund is committed to allocating a minimum of 80% of its total capital (excluding any collateral from securities lending) to the securities included in this quality-focused index.
