Restricted common stock is granted to certain employees as part of the Company's 2005 Plan. As of December 31, 2012, there was $4,052,000 of total unrecognized compensation costs related to the outstanding restricted stock, which is expected to be recognized over a weighted average period of 3.18 years. The Company used 0% for both the discount factor and forfeiture rate for determining the fair value of restricted stock. The forfeiture rate was based on historical results and trends and the Company does not consider discount rates to be material.
