Boston-based NorthStar Asset Management (NSAM), which owns 50,000 shares of Facebook and has $250 million under management, has filed shareholder proposals with Facebook, asking the company to overhaul its share structure so that every share is good for one vote. At issue, according to Northstar, is a bedrock principle of publicly traded companies: accountability to shareholders. Their argument is that if a company intends to "get into everything" and make itself into a "mega-company of the world," as Facebook clearly does, then it is problematic when it is not accountable to "the very people who made it so wealthy"—and powerful. Moreover, it is the shareholder, according to Northstar, who presses thorny issues, such as boardroom diversity and environmental practices. Facebook's actions this week curtail, if not end, investors' ability to do this. NorthStar has a point. Allowing company founders to block shareholder voting rights appears counterintuitive, even unjust.
