EAGG puts the aggregate bond market through an ESG filter. All US Treasury, MBS, CMBS, and ABS exposure is preserved at market weight, as these securities are viewed as ESG-neutral. Remaining constituents (corporate bonds and government-related bonds) are excluded if the entities are involved in tobacco, controversial weapons, or civilian firearms, as well as entities involved in very severe business controversies. The remaining bonds are then scored based on general ESG criteria, such as pollution, anti-competitive practices, and health and safety. The final portfolio is optimized to maximize the average ESG score, while preserving marketlike risk and return characteristics. EAGG focuses on investment-grade bonds of various maturities.
