Nuveen ESG Large-Cap Value ETF (NULV) Exchange: BATS

The Fund seeks to track the investment results of the Index, which is comprised of equity securities issued by large capitalization companies listed on U.S. exchanges that meet certain environmental, social, and governance (“ESG”) criteria. The Index selects from the securities included in the MSCI USA Value Index (the “Base Index”), which generally consists of large-and mid-capitalization U.S. equity securities that exhibit overall value style characteristics based on three variables: book value to price, 12-month forward earnings to price, and dividend yield. MSCI Inc. (“MSCI”), is the index provider for the Index and the Base Index. The Index and the Base Index are owned, calculated and controlled by MSCI, in its sole discretion. Neither the sub-adviser nor its affiliates has any discretion to select Index components or change the Index methodology. As of December 31, 2019, the Index was comprised of 147 securities.The Index identifies equity securities from the Base Index that satisfy certain ESG criteria, based on ESG performance data collected by MSCI ESG Research, Inc. 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. Index rules generally exclude companies with significant activities in certain controversial businesses, including those involving alcohol, tobacco, nuclear power, gambling, and firearms and other weapons, among others. Companies otherwise eligible for inclusion in the Index that exceed certain carbon-based ownership and emissions thresholds are excluded from the Index.Companies that meet the ESG criteria are then ranked within their respective sectors based on their ESG performance score. The highest ranked companies in each sector are identified as eligible for inclusion in the Index until such point that the aggregate weight of companies in the sector reaches 50% of the market cap of such sector in the Base Index. For example, if the market capitalization of all consumer discretionary sector companies included in the Base Index totals $200 million, then the Index would screen these consumer discretionary sector companies, rank them based on ESG performance scores, and add the highest scoring companies to the Index until such point that their combined total market capitalization reaches $100 million. Once the universe of eligible Index components is established, MSCI optimizes the weightings of individual components to approximate the sector weightings of the Base Index, within certain constraints established by the Index. In seeking to track the investment results of the Index, the Fund attempts to replicate the Index by investing all, or substantially all, of its assets in the securities represented in the Index in approximately the same proportions as the Index. The Index is normally rebalanced and reconstituted quarterly in February, May, August, and November. The Index may also remove a security at any time in response to a corporate event such as bankruptcy, delisting, merger or acquisition that causes the security to become ineligible for inclusion in the Index.  The Fund makes changes to its portfolio shortly after any Index changes are made public. 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. In addition, 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 the securities of large-capitalization companies. Large-capitalization companies are defined as companies that fall in the range of companies included in the MSCI USA Large Cap Index as of the last business day of the month in which its most recent reconstitution was completed. The MSCI USA Large Cap Index is designed to measure the performance of the large cap segments of the U.S. market. As of December 31, 2019, the MSCI USA Large Cap Index had a float-adjusted market capitalization range from $3.7 billion to $1.3 trillion, with an average market capitalization of $81.2 billion. “Float-adjusted” means that the share amounts used in calculating the Index reflect only shares available to investors, with shares held by control groups, public companies and government agencies excluded. To the extent the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of companies in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Index.
