Stock-Based Compensation
Note 2: Stock-Based Compensation

The Company had a stock option plan, the 1999 Stock Option Plan, that was adopted in 1999 and that was terminated on March 9, 2009. From 1999 to 2005, incentive stock options were granted annually to key employees of NBI and its subsidiaries. None have been granted since 2005.  All of the outstanding stock options are vested. Because there have been no options granted in 2011 and all options were fully vested at December 31, 2008, there is no expense included in net income for the periods presented.
