Invesco DB Base Metals Fund (DBB) disclosed that the underlying index provider, Deutsche Bank AG, is implementing changes to the index methodology the fund tracks. Eligible commodities will be selected annually based on liquidity and economic importance, and the index universe is expected to expand under the new rules. The current Optimum Yield methodology will be modified to remove contracts with limited liquidity, and static commodity allocations will be replaced by a rules-based annual review to better reflect global production and market liquidity. Sector and single-commodity caps and floors will be added to limit concentration risk, and an intra-year rebalance may be triggered if large deviations occur. The filing states these changes will not affect the Fund's investment objective.
