The State Street SPDR Nuveen ICE High Yield Municipal Bond ETF (HYMB) endeavors to achieve investment results that, before factoring in fees and expenses, generally replicate the price and yield performance of the ICE US Select High Yield Crossover Municipal Index. This benchmark, which employs a market capitalization-weighting methodology, is designed to monitor the returns of U.S. dollar-denominated, tax-exempt municipal debt. Such debt is publicly issued in the U.S. domestic market by American states, territories, and their associated political entities, and is specifically characterized by either a lower credit rating (A3/A+ or inferior) or an unrated status. On the final calendar day of each month, the index undergoes a process of rebalancing and reconstitution.
