After many months of data breach disclosures and sexual harassment scandals, of frustration about perceived pay inequality and insular boardrooms, the largest financial institutions in the world have finally had enough. Larry Fink, CEO of BlackRock, fired the first warning shot this year, when in January he issued his annual letter to CEOs, titled “A Sense of Purpose.” In the letter, Fink asked public companies not only to deliver increasing returns but to demonstrate how they make a “positive contribution to society.” And in March, the Council of Institutional Investors (CII), which represents 130 pension funds managing more than $3.5 trillion in assets, called for corporate boards to adopt stricter guidelines for executives violating sexual harassment codes.
