Income Taxes&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: ''Times New Roman'', Times, serif; text-align: left;"&gt;For the three and six months ended June 30, 2013, the Company&amp;#8217;s tax provision was $90,000 and $72,000, compared to $89,000 and $186,000 for the three and six months ended June 30, 2012. The Company&amp;#8217;s income tax provision for the three and six-month periods ended June 30, 2013 and 2012 was primarily related to income taxes of the Company&amp;#8217;s international operations, as a full valuation allowance was applied against all U.S. federal and state deferred tax assets arising during the respective periods.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: ''Times New Roman'', Times, serif; text-align: left;"&gt;The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. As of June 30, 2013 and December 31, 2012, the Company had a 100% valuation allowance against its U.S. deferred tax assets. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considered available positive and negative evidence giving greater weight to its recent cumulative losses and its ability to carry-back losses against prior taxable income and lesser weight to its projected financial results due to the challenges of forecasting future periods. The Company also considered, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: ''Times New Roman'', Times, serif; text-align: justify;"&gt;On January 2, 2013, the President signed into law The American Taxpayer Relief Act of 2012, or ATRA. Under prior law, a taxpayer was entitled to a research tax credit for qualifying amounts incurred through December 31, 2011. The ATRA extends the research credit for two years for qualified research expenditures incurred through the end of 2013. The extension of the research credit is retroactive and includes amounts incurred after 2011. The benefit of the reinstated credit did not impact the Company&amp;#8217;s statement of operations for the three and six months ended June 30, 2013, as the research and development credit carryforwards are offset by a full valuation allowance.&lt;/div&gt;&lt;/div&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for income taxes.
