FLTR tracks an index of US investment-grade debt, focusing on floating-rate notes issued by corporate entities or similar commercial entities in the United States. This exposure gives it a somewhat riskier portfolio compared to other funds, and a smaller selection of securities to work with. Securities must be denominated in USD to be included in the index and must have a minimum of 6 months remaining to maturity. Each component of the index is weighted by market value and capped at 2% of the portfolio. FLTR uses a sampling method to track its index, and will only invest in a subset of securities in an effort to hold a portfolio of bonds with the same risk and return characteristics of the index. Rebalancing occurs monthly. Prior to Sept. 1, 2022 the ETF's name was VanEck Investment Grade Floating Rate ETF. The underlying index, to which the ETF tracks, did not change in targeted credit quality.
