The Company has recognized share-based compensation expense from continuing operations of approximately $77 thousand and $121 thousand for the six months ended June 30, 2013 and 2012, respectively. The total non-cash, share-based compensation expense from continuing operations included in the unaudited condensed consolidated statements of operations for the periods presented is included in the following expense categories:
There was no share-based compensation expense from discontinued operations for the three and six months ended June 30, 2013. Share-based compensation expense from discontinued operations was zero and $(7) thousand for the three and six months ended June 30, 2012, respectively. No share-based compensation expense was capitalized during the six months ended June 30, 2013 and 2012. Compensation expense related to stock options to be charged in future periods amounts to approximately $52 thousand at June 30, 2013 and will be recognized over a weighted-average period of 1.08 years as follows:
The Company estimates forfeitures at the time of grant and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates in order to derive the Company’s best estimate of awards ultimately expected to vest. Forfeitures represent only the unvested portion of a surrendered option and are typically estimated based on historical experience. At June 30, 2013, the Company had outstanding options under two option plans: the 1996 Equity Incentive Plan (the “1996 Plan”) and the 2007 Stock Equity Plan (the “2007 Plan”, together the “Plans”). Both Plans were approved by stockholders and provided that the Board of Directors may grant options to purchase the Company’s common stock to key employees and directors of the Company. Incentive and non-qualified options must be granted at least at the fair market value of the common stock or, in the case of certain optionees, at 110% of such fair market value at the time of grant. The options may be exercised, subject to certain vesting requirements, for periods up to ten years from the date of issue. The 1996 Plan expired with respect to the issuance of new grants as of December 10, 2006. Accordingly, future grants may be made only under the 2007 Plan. A summary of options outstanding under the Plans as of June 30, 2013 and changes during the six month period ended June 30, 2013 is as follows:
The aggregate intrinsic value in the table above represents the total intrinsic value, based on the Company’s closing stock price of $0.56 as of June 30, 2013, which would have been received by the option holders had all option holders exercised their options as of that date. The total intrinsic value of options exercised was approximately zero and zero for the six months ended June 30, 2013 and 2012, respectively. The total intrinsic value of options expected to vest at June 30, 2013 was approximately zero, and the weighted average remaining contractual life of outstanding options that are expected to vest is 5.31 years.
