Income Tax Disclosure [Abstract] |
Income Tax, Policy [Policy Text Block] | In July 2013, the Financial Accounting Standards Board (“FASB”) issued an update to the accounting standard regarding income taxes. This update provides guidance concerning the balance sheet presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward (the “Carryforwards”) is available. This accounting standard requires an entity to net its liability related to unrecognized tax benefits against the related deferred tax assets for the Carryforwards. A gross presentation will be required when the Carryforwards are not available under the tax law of the applicable jurisdiction or when the Carryforwards would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax position. This update is effective for fiscal years and interim periods within such years beginning after December 15, 2013. We adopted this update in the first quarter of 2014. In July 2013, the FASB issued an update to the accounting standard regarding income taxes, which we adopted in the first quarter of 2014. This update provides guidance concerning the balance sheet presentation of an unrecognized tax benefit when Carryforwards are available. This accounting standard requires us to net our liability related to unrecognized tax benefits against the related deferred tax assets for the Carryforwards. A gross presentation will be required when the Carryforwards are not available under the tax law of the applicable jurisdiction or when the Carryforwards would not be used to settle any additional income taxes resulting from disallowance of the uncertain tax position. We are required to establish a valuation allowance against our DTA when it is more likely than not that all or some portion of our DTA will not be realized. At each balance sheet date we assess our need for a valuation allowance. Our assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our DTA will be realized in future periods. In making this assessment, the primary negative evidence that we considered was our cumulative losses in recent years and the continued uncertainty around our future results. We also considered positive evidence when assessing the need for a valuation allowance, such as future reversals of existing taxable temporary differences, future projections of taxable income, taxable income within the applicable carryback periods and potential tax planning strategies. In assessing our need for a valuation allowance, the weight assigned to the effect of both negative and positive evidence is commensurate with the extent to which such evidence can be objectively verified. We provide for income taxes in accordance with the provisions of the accounting standard regarding accounting for income taxes. As required under this standard, our deferred tax assets and liabilities are recognized under the balance sheet method, which recognizes the future tax effect of temporary differences between the amounts recorded in our condensed consolidated financial statements and the tax bases of these amounts. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax asset or liability is expected to be realized or settled.
