Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Deferred federal and state income tax assets primarily represent the deferred tax benefits arising from temporary differences between book and tax income which will be recognized in future years as an offset against future taxable income. These assets were largely generated as a result of inventory impairments that the Company incurred in 2006 through 2011. If, for some reason, the combination of future years' income (or loss), combined with the reversal of the timing differences, results in a loss, such losses can be carried back to prior years or carried forward to future years to recover the deferred tax assets. In accordance with ASC 740-10, Income Taxes, we evaluate our deferred tax assets, including the benefit from net operating losses (“NOLs”), to determine if a valuation allowance is required. Companies must assess, using significant judgments, whether a valuation allowance should be established based on the consideration of all available evidence using a “more likely than not” standard with significant weight being given to evidence that can be objectively verified. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the length of statutory carryforward periods, our experience with operating losses and our experience of utilizing tax credit carryforwards and tax planning alternatives. Based upon a review of all available evidence, we recorded a full valuation allowance against our deferred tax assets during 2008. We continue to maintain a full non-cash valuation allowance against the entire amount of our remaining net deferred tax assets at March 31, 2013 as we have determined that the weight of the negative evidence exceeds that of the positive evidence and it continues to be more likely than not that we will not be able to utilize all of our deferred tax assets and NOL carryovers. For the three months ended March 31, 2013, the Company had a valuation allowance of $134.0 million against deferred tax assets which include the tax benefit from NOL and credit carryovers. At March 31, 2013, the Company had federal net operating loss carryforwards of approximately $82.3 million and federal credit carryforwards of $4.2 million and $16.1 million of state net operating loss carryforwards. Our future deferred tax asset realization depends on sufficient taxable income in the carryforward periods under existing tax laws. Our federal carryforward benefits will begin to expire in 2028. Our state net operating loss benefits began to expire in 2012, with $9.0 million expiring between 2012 and 2027 and $7.1 million expiring between 2028 and 2033. We will continue to review on an ongoing basis all available evidence to determine if and when we expect to realize our deferred tax assets and NOL carryovers. Additionally, due to the considerable estimates utilized in establishing a valuation allowance and the potential for changes in facts and circumstances in future reporting periods, it is reasonably possible that we will be required to either increase or decrease our valuation allowance in future reporting periods. During the three months ended March 31, 2013, the Company reduced its valuation allowance by $1.8 million, for a total valuation allowance recorded of $134.0 million, against its deferred tax assets. The accounting for deferred taxes is based upon an estimate of future results. Differences between the anticipated and actual outcomes of these future tax consequences could have a material impact on the Company's consolidated results of operations or financial position.
