The provision for income taxes primarily consisted of foreign taxes.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Due to the Company&amp;#8217;s history of cumulative operating losses, management concluded that, after considering all the available objective evidence, it is not more likely than not that all the Company&amp;#8217;s net deferred tax assets will be realized. Accordingly, all of the U.S. deferred tax assets continue to be subject to a valuation allowance as of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;As of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, there have been &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;no&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; material changes to the total amount of unrecognized tax benefits.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;During the three and six months ended June 30, 2012, the company recorded an income tax benefit of approximately &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$37.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$37.1 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, respectively.&amp;#160;The income tax benefit resulted primarily from a reduction in the valuation allowance recorded against the Company's net deferred tax assets of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$37.5 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; recorded during the second quarter of 2012, due to deferred tax liabilities recognized for the difference between the fair value and carrying basis of certain tangible and intangible assets obtained as part of the Acquisition, which can be used as a source of income to support realization of certain domestic deferred tax assets.&amp;#160; &amp;#160;&amp;#160;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;As described in the Company's Quarterly Report on Form 10-Q for the nine months ended September 30, 2012 in Note 2. "Acquisition", the Condensed Consolidated Statements of Operations for the six months ended June 30, 2012 includes adjustments that were made upon finalization of the valuation of certain assets acquired and liabilities assumed from the acquisition of eBioscience Holdings, Inc. ("eBioscience"). Deferred tax liabilities recognized for the difference between the fair value and carrying basis of certain tangible and intangible assets obtained as part of the Acquisition can be used as a source of income when utilizing certain domestic deferred tax assets. The aforementioned purchase accounting adjustments that reduced certain tangible and intangible assets and reduced the related deferred tax liabilities resulted in an increase in the valuation allowance recorded against the Company's consolidated net deferred tax assets. Under Accounting Standards Codification ("ASC") 805-740, changes in an acquirer's valuation allowances that stem from a business combination should be recognized as an element of the acquirer's deferred income tax expense (benefit) in the reporting period that includes the business combination. &amp;#160;Such purchase accounting adjustments (also referred to as &amp;#8220;measurement period adjustments&amp;#8221;) are considered to have occurred as of June 25, 2012 (the "Acquisition Date"). As a result of the retrospective purchase accounting and related income tax valuation adjustments from the Acquisition, the Company recast its income tax benefit for the second quarter of 2012, lowering it by &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$7.2 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; from net &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$44.3 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; with a corresponding increase in valuation allowance. The Company's Condensed Consolidated Financial Statements as of and for the period ended June 30, 2012, were recast to reflect these adjustments.&lt;/font&gt;&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.
