Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Share-based Compensation Arrangement by Share-based Payment Award, Description	The Company’s 2006 Stock Incentive Plan, as amended and restated (the “2006 Plan”), authorizes the Company to issue up to 3,000,000 shares of common stock to employees, non-employee directors and consultants pursuant to awards of stock options, stock appreciation rights, restricted stock, in payment of performance shares or other stock-based awards. Under the 2006 Plan, stock options must be granted at a price not less than the fair market value of the stock on the date the option is granted, generally are not subject to re-pricing, and will not be exercisable more than ten years after the date of grant. Options granted under the 2006 Plan generally qualify as “non-qualified stock options” under the U.S. Internal Revenue Code. Certain options granted under the Company’s 2004 Common Stock Option Plan, as amended (the “2004 Plan”), generally qualify as “incentive stock options” under the U.S. Internal Revenue Code; the exercise price of a stock option granted under this plan may not be less than the fair market value of common stock on the option grant date.
