Income Taxes	5. Income Taxes During the three and nine months ended September 30, 2015, we recorded foreign tax expense of $147 and $810, respectively. Foreign taxes during the three and nine months ended September 30, 2015 includes $168 of deferred tax benefits and $198 of deferred tax expense, respectively. Foreign taxes for the three and nine months ended September 30, 2015 also include $315 and $612, respectively, of current tax expense associated with amounts payable for provincial taxes. During the three and nine months ended September 30, 2014, we recorded foreign deferred tax expense of $10 and foreign deferred tax benefits of $33, respectively. Deferred income taxes reflect the tax effects of temporary differences between the basis of assets and liabilities recognized for financial reporting and tax purposes, and net operating loss and tax credit carryforwards. The significant components of our total deferred tax liability as of September 30, 2015 relate to the tax effects of the basis differences between the intangible assets acquired in the DNAG acquisition for financial reporting and tax purposes. In 2008, we established a full valuation allowance against our U.S. deferred tax asset. Management believes the full valuation allowance is still appropriate as of September 30, 2015 and December 31, 2014 since the facts and circumstances necessitating the allowance have not changed. As a result, no U.S. federal or state income tax benefit was recorded for the three and nine-month periods ended September 30, 2015 and 2014.
