OKLAHOMA CITY -- Sunrise Senior Living ( SRZ) investors hope that company leaders will finally see the light. Sunrise shareholders got their chance at Tuesday's annual meeting to push for corporate reforms. But critics fear that Sunrise, which has yet to release any voting results, remains blind to shareholder concerns. A dissident shareholder group says half of Sunrise's directors -- including an embattled audit-committee member up for re-election -- failed to even attend the meeting. The shareholders say the company offered no good reason for its board's poor showing. "The excuse we heard from the company was that the judge had imposed this date for the meeting and -- although it was set over a month ago -- the directors were unable to schedule around it," says Richard Clayton, a research director at Change to Win Investment Group. "But even with relatively short notice, a significant number of shareholders managed to attend. ... It was pretty remarkable." Meanwhile, the dissidents say shareholders showed up in force. CtW urged its followers, including some large union-affiliated pension funds, to show up in person at Tuesday's meeting so that they could cast formal votes showing their displeasure with the company. Specifically, they recommended that shareholders withhold votes for Craig Callen -- who sits on an audit committee that failed to catch serious accounting mistakes -- and support proposals to declassify Sunrise's board and force company executives to return any ill-gotten stock-option gains.
