Fund Description: NuShares Enhanced Yield U.S. Aggregate 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 NuShares Enhanced Yield U.S. Aggregate Bond ETF seeks to provide investment returns that closely correspond to the price and yield performance of the BofA Merrill Lynch Enhanced Yield US Broad Bond Index. INDEX DESCRIPTION: The BofA Merrill Lynch Enhanced Yield US Broad Bond Index is designed to broadly capture the U.S. investment grade fixed income market, as represented by the BofA Merrill Lynch US Broad Market Index (the Base Index). Unlike the Base Index, the Index does not capitalization-weight component securities. Instead, the Index first assigns component securities from the Base Index into a variety of categories based upon asset class, sector, credit quality and maturity. The Index then employs a rules-based methodology to allocate higher weights to categories with the potential for higher yields than the Base Index while seeking to maintain risk and credit quality at levels similar to those of the Base Index by limiting the amount of deviation between the two indices with respect to sector and category weights, tracking error, duration, and turnover. After assigning weights at the category level the Index then distributes each category weight among the category’s individual component securities based on their relative market capitalizations. The Base Index and the Index are both rebalanced on a monthly basis. The Index draws from the universe defined by the Base Index, which consists of U.S. dollar-denominated, investment grade taxable debt securities with fixed rate coupons that have at least one year to final maturity. The Index is principally comprised of U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-backed securities, and U.S. dollar denominated debt securities issued by non-U.S. governments and corporations that are publicly offered for sale in the United States. A significant portion of the bonds represented in the Index are U.S. agency mortgage-backed pass-through securities. FUND STRATEGY: The Fund seeks to track the investment results 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. Under normal market conditions, the Fund invests at least 80% of its assets, exclusive of collateral held from securities lending, in component securities of the Index. Under normal market conditions, the Fund will (i) invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in fixed income securities and (ii) invest at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in U.S. dollar-denominated securities that are publicly offered for sale in the United States. The Fund may invest up to 20% of its assets in securities and other instruments not included in the Index (including fixed income securities, derivatives, other investment companies, including other exchange-traded funds (ETFs), and cash and cash equivalents) FUND MANAGEMENT: Nuveen Fund Advisors, LLC serves as the Investment Adviser to the Fund. Teachers Advisors, Inc. serves as the Sub-Adviser to the Fund.
