ISMD follows a principles-based, biblically responsible investing philosophy, screening for firms with products and policies aligned to evangelical Christian values. It screens out companies with any degree of involvement in certain activities: abortion, gambling, alcohol, human rights violations, and LGBT lifestyle. ISMD scores remaining firms by how well they align with its values, considering factors such as family time for employees, community philanthropy, environmental protection, or products that treat disease or support education. The 500 highest-scoring firms receive equal weights in the fund. The fund employs an equal-weighting scheme, which may cause a tilt toward smaller firms. The index is rebalanced quarterly. Between March 30 and August 19, 2022, the fund's name included a reference to 'ESG'. The name changes did not impact the fund strategy.
