CHI practices shareholder activism by purchasing shares in publicly-traded corporations and engaging with corporate management on environmental, social and corporate governance issues. Following the 2018 Stoneman Douglas High School shooting, in example; Catholic Health Initiatives was the lead filer, co-filing with the Adrian Dominican Sisters, of a shareholder resolution asking firearms manufacturer Sturm, Ruger &amp; Co. to report to investors regarding the steps they are taking to reduce gun violence. Ruger opposed the resolution. BlackRock, the world's largest asset manager and Ruger's largest investor, as well as Institutional Shareholder Services and Glass Lewis, the two most important shareholder advisory firms in the United States, supported the resolution. At Ruger's annual meeting on May 9, 2018, 69 percent of shareholders voted in favor and Ruger agreed to heed the resolution. The Brady Campaign to Prevent Gun Violence called the vote a "first-of-its-kind victory."
