AUMI provides exposure to the global gold mining industry by investing in the securities of the largest gold miners included in the underlying index. It also holds ADRs and GDRs that are based on such securities. Selection begins with identifying the investible universe based on listing, revenue, size, and liquidity requirements. Eligible positions are then ranked according to their free float market-cap with the largest 20-30 firms prioritized as index constituents. Final decisions regarding index composition are at the discretion of the index committee. Each index component is then weighted proportionally according to its free float market-cap, limited to 4.75%. Note that the fund uses a replication strategy where it will invest in all the underlying securities and hold them in the same ratio as they are seen in the index. AUMI may also engage in lending activities up to 1/3 of the value of the funds assets. The index is adjusted yearly in February and reweighted annually in August.
