NULG invests in companies within the MSCI USA Growth Index (the parent index) which exhibit positive ESG characteristics. The growth aspect is determined by five metrics: long- and short-term forward EPS growth, current internal growth rate, long-term forward EPS, and long-term historical sales growth. The index then ranks companies within the parent index according to their impact on climate change, natural resource use, waste and emission management, safety, ethics, and compliance with national and international rules and regulations, among other categories. Companies with significant activity involving weapons, gambling, alcohol, and tobacco are specifically excluded. The top 50% of these ESG-ranked growth companies are selected for inclusion, per sector within the index and then weighted by a multi-factor optimizer that aims to keep holdings and performance similar to the parent index. The index is rebalanced and reconstituted quarterly starting each February.
