Fund Description: Nuveen ESG High Yield Corporate Bond ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the Nushares ETF Trust, an open-end investment management company. INVESTMENT OBJECTIVE: The Nuveen ESG High Yield Corporate Bond ETF seeks to provide investment returns that closely correspond to the price and yield performance of the Bloomberg Barclays MSCI US High Yield Very Liquid ESG Select Index. INDEX DESCRIPTION: The Bloomberg Barclays MSCI US High Yield Very Liquid ESG Select Index utilizes certain environmental, social, and governance (ESG) criteria to select from the securities included in the Bloomberg Barclays US High Yield Very Liquid Index (the Base Index), which is designed to broadly capture the U.S. dollar-denominated, high yield, fixed-rate corporate bond market. The Index draws from the universe defined by the Base Index, which is comprised of U.S. dollar-denominated, below investment grade, corporate bonds with above average liquidity. Below investment grade securities are commonly referred to as high yield or junk bonds. The Base Index is comprised of fixed-rate, taxable corporate bonds that have a remaining maturity of at least one year regardless of optionality, and have $500 million or more of outstanding face value. To be eligible for inclusion in the Base Index, a bond must have been issued in the past 5 years. The Base Index also limits the exposure of each issuer to 2% of the Base Index. With respect to corporate debt securities, ESG performance is measured on an industry-specific basis, with assessment categories varying by industry. Environmental assessment categories can include how a company is addressing climate change, natural resource use, and waste management and emission management. Social evaluation categories can include a company’s relations with employees and suppliers, product safety and sourcing practices. Governance assessment categories can include governance practices and business ethics. The ESG criteria also consider how well a company adheres to national and international laws and regulations as well as commonly accepted global norms related to ESG matters. Eligible securities are then market value weighted within each sector, with sector weights in the Index adjusted to mirror the sector exposure of the Base Index. Eligible securities are sorted into a series of groups according to credit rating and ESG score. FUND STRATEGY: Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the Index. The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally invests in a sample of the securities in the Index whose risk, return and other characteristics resemble the risk, return and other characteristics of the Index as a whole. The Index is rebalanced and reconstituted monthly. ESG ratings employed by the Index are generally updated annually, but may be reviewed more frequently in the index provider’s discretion. The Fund makes corresponding changes to its portfolio shortly after any Index changes are made public. FUND MANAGEMENT: Nuveen Fund Advisors, LLC serves as the investment adviser to the Fund. Teachers Advisors, LLC serves as the Sub-Adviser.
