The Fund seeks to track the investment results of the ICE AMT-Free New York Plus Municipal Index (the Underlying Index), which generally measures the performance of U.S. dollar denominated investment grade tax-exempt debt publicly issued in the U.S. domestic market by the state of New York and its political subdivisions. The Underlying Index includes a 5 percent weighting to U.S. dollar denominated investment grade tax-exempt debt publicly issued in the U.S. domestic market by states other than New York and such states' political subdivisions. As of February 29, 2024, there were 6,551 issues from New York and 19,372 issues from U.S. states excluding New York in the Underlying Index. As of February 29, 2024, a significant portion of the Underlying Index is represented by municipal bonds. The components of the Underlying Index are likely to change over time.
