Income Tax Disclosure [Abstract]
Income Taxes	14. Income Taxes We account for income taxes as required by FASB ASC Topic No. 740, Income Taxes. This Topic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Topic also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Topic requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. The amount recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. In addition, the Topic permits an entity to recognize interest and penalties related to tax uncertainties either as income tax expense or operating expenses. The Company has chosen to recognize interest and penalties related to tax uncertainties as operating expense. The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carryforwards. In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. A significant factor in the Company’s assessment is that the Company was in a four-year historical cumulative loss as of the end of December 31, 2012. This fact, combined with uncertain near-term market and economic conditions, reduced the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets. After a review of the four sources of taxable income as of December 31, 2012 (as described above), and after consideration of the Company’s four-year cumulative loss position as of December 31, 2012, the Company has recorded valuation allowances related to its U.S.-based deferred tax amounts, with a corresponding charge to income tax expense, of $60.5 million as of December 31, 2012. In April 2013, the Internal Revenue Service began its examination of the Company’s U.S. Federal tax return for the years ended December 31, 2009, 2010 and 2011. We may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results. It is the Company’s policy to classify any interest and/or penalties in the financial statements as a component of general and administrative expense.
