401(k) Plan

Note 16. 401(k) Plan

Our 401(k) Plan covers substantially all of our employees. Participants in the plan are permitted to contribute a fixed percentage of their total annual cash compensation to the plan (subject to the maximum employee contribution defined by law). We match 50% of employee contributions, up to a maximum of 6% of each employee’s eligible compensation in the form of shares of common stock. We recorded an expense of $165,000 in 2011, $191,000 in 2010, and $168,000 in 2009 for our contributions under our 401(k) Plan.
