Income Taxes
The Company accounts for income taxes under ASC 740-10. Deferred income tax assets and liabilities are determined based upon differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reversed. A valuation allowance is required to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. At September 30, 2013 and December 31, 2012, the Company provided a valuation allowance for the full amount of its net deferred tax asset because realization of any future tax benefit was not sufficiently assured.
Income tax expense (benefit) consists of the following (in thousands):

In the three and nine months ended September 30, 2013 and 2012, the current portion of income tax expense primarily relates to state, local and foreign taxes and the deferred portion primarily relates to federal and state tax amounts.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes as well as federal and state net operating losses and tax credit carryforwards. At September 30, 2013 and December 31, 2012, the Company included $0.5 million of current deferred tax assets in prepaid expenses and other current assets. At September 30, 2013 and December 31, 2012, the Company included $0.8 million and $0.7 million, respectively of non-current deferred tax liabilities in other long-term liabilities on its balance sheet.
In the future, the Company will generate additional deferred tax assets and liabilities related to its amortization of acquired intangible assets for tax purposes because these long-lived intangible assets are not amortized for financial reporting purposes. The tax amortization in future years will give rise to a temporary difference and a tax liability, which will only reverse at the time of ultimate sale or further impairment of the underlying intangible assets. Due to the uncertain timing of this reversal, the temporary difference cannot be considered as a source of future taxable income for purposes of determining a valuation allowance; therefore, the tax liability cannot be used to offset the deferred tax asset related to the net operating loss carryforward for tax purposes that will be generated by the same amortization.
The Company had no unrecognized tax benefits at September 30, 2013.
