During 2005 and 2004 the Company granted options with a weighted average grant-date fair value of $5.88 and $3.58 per option, respectively, based on the following assumptions:  
 
 
  Restricted Stock. The Company grants shares of restricted stock and records deferred compensation based on the closing price of the Company’s stock on the grant date. The deferred compensation is amortized to stock-based compensation expense ratably over the vesting period of the restricted shares (generally one to three years). The unamortized deferred compensation obligation amounted to $6.3 million as of December 31, 2006. The Company recorded compensation expense related to restricted stock of approximately $2.4 million and $0.4 million for the years ended December 31, 2006 and 2005, respectively. The table below summarizes restricted stock activity for the years ended December 31, 2006 and 2005:  
 
 
 

Taxes. Upon settlement of stock awards, the Company recognizes any difference between book compensation expense and tax compensation expense as a tax windfall or shortfall. The difference is charged to equity in the case of windfall. In the case of shortfalls, the difference is charged to equity to the extent of previously recognized windfall tax benefits and any remaining is recognized as additional income tax expense. When the settlement of an award results in a net operating loss (NOL), or increases an NOL carryforward SFAS 123(R) prescribes that no windfall should be recognized until the deduction reduces income tax
