At September 30, 2011 and December 31, 2010, respectively, we had no material unrecognized tax benefits or accrued interest and penalties. Tax years 2008 through 2010 remained open for examination at September 30, 2011. We provide a valuation allowance when we believe it is more likely than not that we will not realize some portion of the tax asset. We established a valuation allowance of $746,368 related to a portion of the net operating loss carryforward of Le Mars at January 1, 2004. We have determined that we are not required to establish a valuation allowance for the other net deferred tax assets of $34.4 million and $29.1 million at September 30, 2011 and December 31, 2010, respectively, since it is more likely than not that we will realize these deferred tax assets through reversals of existing temporary differences, future taxable income and the implementation of tax planning strategies. At September 30, 2011, we have a net operating loss carryforward of $4.9 million related to the tax loss we incurred in 2011, which is available to offset our future taxable income and will expire in 2031 if not utilized. We also have a net operating loss carryforward of $7.1 million related to Le Mars, which will begin to expire in 2011 if not utilized and is subject to an annual limitation in the amount that we can use in any one year of approximately $376,000.
