Further complicating matters is that Dane Christensen, George Serafeim and Anywhere Sikochi, authors of the 2021 study, “ Why Is Corporate Virtue in the Eye of the Beholder? The Case of ESG Ratings,” published in The Accounting Review, found that greater firm ESG disclosure generally exacerbates ESG rating disagreement rather than resolving it. In addition, the return and risk of ESG funds can differ significantly and are driven by fund-specific criteria rather than by a homogeneous ESG factor. Florian Berg, Julian Kölbel and Roberto Rigobon, authors of the 2019 study, “ Aggregate Confusion: The Divergence of ESG Ratings,” found that most of the divergence in ratings could be traced to measurement and scope divergence, while weight divergence seemed to play a minor role.īecause of the divergence in ratings, funds may not be aligned with investor objectives and beliefs. Third, raters attach different weights to the different categories (“weight divergence”) when generating an aggregated ESG rating. Raters measure identical categories differently (“measurement divergence”). Raters use different categories, which can lead to disagreement (referred to as “scope divergence”). The result is that there can be a wide disparity of ESG ratings for the same company.ĭivergence in ratings has three sources. My August 24, 2020, Novemand Jarticles for Advisor Perspectives presented evidence from research demonstrating that ESG investors face considerable challenges in allocating assets because the data used to construct ESG portfolios differ so widely among providers. 1 While there are seven competing vendors providing ratings to measure how companies perform along ESG standards, those ratings differ widely across vendors. New research shows that those stocks with the greatest divergence had higher performance.īy the end of 2020, there was an estimated $35 trillion of assets (up from $23 trillion in 2016) managed under environmental, social and governance (ESG) principles – ESG investing has entered the mainstream of investing. All rights reserved.A well-established problem facing investors with an environmental, social and governance (ESG) mandate is the wide divergence of ratings assigned to companies by different vendors. The results showed that USC-CM Exos is absorbed into human skin, it promotes Collagen I and Elastin synthesis in the skin, which are essential to skin rejuvenation and shows the potential of USC-CM integration with the cosmetics or therapeutics.Ĭonditioned media from hUCB-MSCs Cosmetics Exosomes Skin permeation USC-CM.Ĭopyright © 2017 Elsevier Inc. Moreover, increased expressions of Collagen I and Elastin were found after 3 days of treatment on human skin. Results showed that Exo-Green labeled USC-CM Exos approached the outermost layer of the epidermis after 3 h and gradually approached the epidermis after 18 h. Moreover, we evaluated skin permeation of USC-CM Exos by using human skin tissues. Our in vitro results showed that USC-CM Exos integrate in Human Dermal Fibroblasts (HDFs) and consequently promote cell migration and collagen synthesis of HDFs. We found that USC-CM has various growth factors associated with skin rejuvenation. In this study, we investigated the roles of exosomes that are derived from USC-CM (USC-CM Exos) in cutaneous collagen synthesis and permeation. Human umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) play an important role in cutaneous wound healing, and recent studies suggested that MSC-derived exosomes activate several signaling pathways, which are conducive in wound healing and cell growth.
