Nuveen ESG U.S. Aggregate Bond ETF Share Price

The fund employs a passive management (or “indexing”) approach, investing in a diversified portfolio of U.S. investment grade bonds that satisfy certain environmental, social and governance (“ESG”) criteria. The fund seeks to track the investment results, before fees and expenses, of the Bloomberg Barclays MSCI US Aggregate ESG Select Index. The Bloomberg Barclays MSCI US Aggregate ESG Select Index (the “Index”) uses a rules-based methodology that seeks to provide investment exposure that generally replicates the Bloomberg Barclays U.S. Aggregate Bond Index (the "Base Index") through a portfolio of securities that adhere to predetermined ESG criteria. The Index is composed of U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-based securities and U.S. dollar-denominated debt securities issued by non-U.S. governments and corporations. The Index is rebalanced monthly. It is not possible to invest directly in an index.
