abrdn Bloomberg All Commodity Strategy K-1 Free ETF (BCI US) – Portfolio Construction Methodology

The underlying Bloomberg Commodity Index Total Return provides broad, futures-based exposure to major physical commodities across energy, grains, softs, industrial metals, and precious metals. Eligible futures are selected for liquidity and deliverability, with contract selection and roll schedules set by rule; target component weights derive from a blend of liquidity (≈2/3) and US-dollar production (≈1/3). Diversification constraints bind at each annual reweight: no single commodity >15% of the index; a commodity plus its derivatives (e.g., petroleum complex) ≤25%; any related sector (e.g., energy, grains, livestock, precious metals) ≤33%; and, where liquidity allows, a single commodity weight is not <2%. Total return adds collateral yield from short-term US Treasury rates to spot-plus-roll returns. The index is rebalanced annually with monthly maintenance implementing rolls and contract lead changes on a preset calendar.
