Income Taxes	6. Income Taxes We are required to file federal and state income tax returns in the United States. The preparation of these tax returns requires us to interpret the applicable tax laws and regulations in effect in such jurisdictions, which could affect the amount of tax paid by us. In consultation with our tax advisors, we base our tax returns on interpretations that are believed to be reasonable under the circumstances. The tax returns, however, are subject to routine reviews by the various federal and state taxing authorities in the jurisdictions in which we file tax returns. As part of these reviews, a taxing authority may disagree with respect to the income tax positions taken by us (“uncertain tax positions”) and, therefore, may require us to pay additional taxes. As required under applicable accounting rules, we accrue an amount for our estimate of additional income tax liability, including interest and penalties, which we could incur as a result of the ultimate or effective resolution of the uncertain tax positions. We account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributed to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carry-forwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to amounts expected to be realized. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized.
