10. Income taxes

Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against the Company’s otherwise recognizable net deferred tax assets.

For the three months ended March 31, 2016, the Company recognized an income tax benefit of $0.1 million and tax expense in other comprehensive loss of $0.7 million related to the unrealized gain on available-for-sale securities during the quarter. As of March 31, 2016, the Company recorded an accrued income tax provision of $0.6 million related to this tax benefit included within accrued expenses and other current liabilities in the condensed consolidated balance sheet, which is expected to be generated from continuing operations.
