[2] The comparability of our income (loss) from operations and net income (loss) per share was affected by the following unusual income or expense items:•During the fourth quarter of 2013, the Company incurred a $12.5 million loss associated with the establishment of a valuation allowance against certain of the Company's foreign deferred tax assets.•During the first quarter of 2013, the Company recorded a $2.9 million loss associated to the write off of the Company's Security Gateway ("SEG") purchased computer software due to management's decision to abandon future development of this technology.•During the first quarter of 2013, the Company recorded a $1.5 million gain associated with the the sale of the Company's OS-9 software assets.•The balance of goodwill was determined to be impaired during the third quarter of 2012, resulting in an impairment charge of $29.7 million. In addition, the Company recorded a $5.9 million gain associated with a decrease in fair value of the contingent consideration related to our acquisition of Continuous Computing.
