Note 9. Income Taxes

The Company’s quarterly income taxes reflect an estimate of the corresponding year’s annual effective tax rate and include, when applicable, adjustments from discrete tax items. For the three months ended March 31, 2015 and 2014, the Company’s tax expense was $50,000 and $37,000, respectively, and was primarily related to income taxes of the Company’s non-U.S. operations as the Company’s U.S. operations were in a loss position and the Company maintains a 100% valuation allowance against its U.S. deferred tax assets.

The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using enacted tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. As of March 31, 2015 and December 31, 2014, the Company had a 100% valuation allowance against its U.S. deferred tax assets. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considered available positive and negative evidence giving greater weight to its recent cumulative losses and lesser weight to its projected financial results due to the subjectivity involved in forecasting future periods. The Company also considered, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies.
