New Northern Trust Sustainability Mutual Fund Northern Trust launched the Northern Global Sustainability Index Fund on March 5th, the first mutual fund to follow the KLD Global Sustainability Index (GSI). The fund includes companies in 24 developing markets that pass KLD's sustainability screens. The GSI tracks 693 mid cap and large cap companies in North America, Europe and Asia-Pacific. Northern Trust's newest fund was created in response to growing consumer demand for sustainable investing. Northern Trust reports the fund fees are 65 basis points with no sales charge, compared to the average 150 basis points that most socially responsible funds charge. Currently, Northern Trust manages over $20 billion in socially screened assets.
