Income Taxes	13. Income Taxes The Company recognized an income tax benefit for the three and six months ended June 30, 2018 of $2.9 million and $5.9 million, respectively, as a result of the intraperiod tax allocation rules under ASC Topic 740-20, Intraperiod Tax Allocation, under which the Company recognized a benefit for current losses as a result of an entry to additional paid-in capital related to the issuance of the Convertible Senior Notes discussed in Note 8, Convertible Senior Notes. The Company did not record any income tax expense or benefit for the three and six months ended June 30, 2019. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its net deferred tax assets, which remain fully reserved. The remaining net deferred tax asset generated from the Company’s net operating loss has been offset by a full valuation allowance because it is more likely than not that the tax benefits of the net operating loss carry forward will not be realized. The Company also recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.
