Income Taxes [Abstract]
Income Taxes	9. Income Taxes On an interim basis, the Company estimates what its anticipated annual effective tax rate will be and records a quarterly income tax provision in accordance with the estimated annual rate, plus the tax effect of certain discrete items that arise during the quarter. As the fiscal year progresses, the Company refines its estimates based on actual events and financial results during the year. This process can result in significant changes to the Company's estimated effective tax rate. When this occurs, the income tax provision is adjusted during the quarter in which the estimates are refined so that the year-to-date provision reflects the estimated annual effective tax rate. These changes, along with adjustments to the Company's deferred taxes and related valuation allowance, may create fluctuations in the overall effective tax rate from quarter to quarter. Due to overall cumulative losses incurred in recent years, the Company maintained a valuation allowance against its deferred tax assets as of June 30, 2013 and December 31, 2012. Over the past twelve quarters the Company has been in a position of overall cumulative losses however we anticipate that by the fourth quarter of the current year, we will be able to demonstrate overall cumulative income in the trailing twelve quarters. While this factor does not in and of itself indicate that the valuation allowance or a portion of the allowance should be removed, it is an indicator that needs to be considered in the evaluation of the valuation allowance. Other factors will also need to be assessed including the future projections of taxable income and the Company's ability to accurately project such taxable income. As such, the Company will be continuously reassessing the appropriateness of releasing the valuation allowance. The Company's effective tax rate for the three and six months ended June 30, 2013 differed from the U.S. federal statutory rate primarily due to the impact of changes in the valuation allowance and to the increase in deferred tax liabilities related to tax deductible indefinite-lived intangible assets.
