The fund provides exposure to large- and mid-cap stocks from Japan by tracking a market cap-weighted index that represents about 85% of the largest Japanese companies. The fund employs a fully rule-based methodology that ranks stocks by total market-cap and assigns a size bucket based on accumulated free float market-cap. The mid-cap size bucket is derived as the difference between the large-cap and large & mid-cap size bucket. Buffer rules are implemented to prevent turnover between the respective size buckets for any subsequent adjustments. The index is rebalanced semi-annually.
