NUSC employs a passive management (or “indexing”) approach, seeking to track the investment results, before fees and expenses, of the TIAA ESG USA Small-Cap Index2. The Fund generally invests in substantially all or a sample of the securities in the Index whose risk, return and other characteristics resemble the risk, return and other characteristics of the index. The Index is composed of equity securities issued by small-capitalization companies listed on U.S. exchanges that meet certain environment, social and governance criteria.
