Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes of $1.7 million for the quarters ended June 27, 2013 and June 28, 2012, reflect effective tax rates of 39.5% and 40.5%, respectively. The provision for income taxes of $2.2 million and $3.2 million for the two quarters ended June 27, 2013 and June 28, 2012, respectively, reflect effective tax rates of approximately 40.0% and 39.5%, respectively. The effective tax rates for the quarters ended June 27, 2013 and June 28, 2012 reflect the impact of certain non-deductible expenses. In assessing the realizable value of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which these temporary differences become deductible. The Company maintains a valuation allowance against deferred tax assets of $2.4 million as of June 27, 2013 and December 27, 2012 as management believes it is more likely than not that certain deferred tax assets will not be realized in future tax periods. Future reductions in the valuation allowance associated with a change in management’s determination of the Company’s ability to realize these deferred tax assets will result in a decrease in the provision for income taxes. The Company files income tax returns in the U.S. federal jurisdiction and certain state jurisdictions as part of the REG income tax filings and files separate income tax returns in various other state jurisdictions as well. The Company's share of the REG current and deferred tax expense is determined on a separate company basis. REG and the Company are no longer subject to U.S. federal income tax examinations by taxing authorities for years before 2009, and with limited exceptions, are no longer subject to state income tax examinations for years before 2008. However, the taxing authorities still have the ability to review the propriety of tax attributes created in closed tax years if such tax attributes are utilized in an open tax year.
