Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Accounting rules governing income taxes require that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. These rules also require that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or the entire deferred tax asset will not be realized. The company evaluates the realizability of its deferred tax assets by assessing its valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization are the company’s historical profitability, forecast of future taxable income and available tax-planning strategies that could be implemented to realize the net deferred tax assets. The company uses tax-planning strategies to realize or renew net deferred tax assets to avoid the potential loss of future tax benefits. A full valuation allowance is currently maintained for all U.S. and certain foreign deferred tax assets in excess of deferred tax liabilities. The company will record a tax provision or benefit for those international subsidiaries that do not have a full valuation allowance against their net deferred tax assets. Any profit or loss recorded for the company’s U.S. operations will have no provision or benefit associated with it due to such valuation allowance, except with respect to withholding taxes not creditable against future taxable income. As a result, the company’s provision or benefit for taxes may vary significantly depending on the geographic distribution of income.
