COMB seeks to deliver a broad, diversified basket of commodities in an actively managed structure. The fund benchmarks the Bloomberg Commodity index but may select investments outside the index methodology. The index considers variables such as economic significance, diversification, continuity, and liquidity when selecting and weighting its contracts so that no single commodity or commodity sector dominates. Utilizing a common structure in the commodity space, the funds futures exposure is held in a Cayman Islands subsidiary while the collateral is actively managed with investments in short-term US fixed income securities. Because of this, investors avoid receiving a K-1 at tax time.
