Editor's Note: Our "Activist Investor" column is now running on Wednesdays. Please bookmark TheStreet.com and check back each week for more analysis of shareholder rights issues.On Wednesday, the Securities and Exchange Commission will hold meetings on whether and how shareholders should be allowed to nominate directors to boards of companies in which they hold stakes. If a rule is agreed upon and put in practice in the next 90 days it could dramatically change the relationship between shareholders and management teams for years to come. The normal course of business since the SEC was created decades ago was that management holds all the cards in selecting its board and insulating itself from criticisms from shareholders. Management picks the directors it wants, it can stagger its re-elections to make it next to impossible to overturn the board in any one year, and shareholders face huge costs and long odds in putting up their own candidates. Even after the Enron and WorldCom scandals earlier this decade, the SEC saw fit to change nothing with respect to making corporate boards more accountable to shareholders. That's about to change. With the latest downturn, and the large antipathy directed towards the SEC from the media and shareholders thanks to its overlooking Bernie Madoff and doing nothing to prevent large institutions like Citigroup ( C), Lehman Brothers, and Bear Stearns from imploding, the SEC can no longer look the other way. Chairwoman Mary Schapiro was brought in with a mandate and, so far, she's giving every indication that she's cleaning house and going the extra mile to give shareholders a voice for their concerns. All this has implications for the number of shareholder activist battles we'll see starting in 2010 and beyond. But more importantly it should truly improve the risk-adjusted returns for all public companies.
