SPRE is passively managed to provide exposure to all Shariah-compliant constituents of the broader S&P Global REIT universe. The underlying index considers all REIT securities listed in both developed and emerging markets that meet minimum market-cap and trading value requirements. Securities are then screened for compliance with Islamic religious laws, such as: maintaining lower debt levels, permissible income below acceptable levels and maintain prescribed cash or asset levels. In addition, the index removes securities involved in business activities that are not Shariah-compliant such as gambling, alcohol, or tobacco. The underlying index is rebalanced and reconstituted monthly.
