Income Taxes
Total income tax expense of $11.0 million, $12.1 million and $7.4 million for the years ended December 31, 2013, 2012 and 2011, respectively, was allocated to income in each year. Income tax expense consists of the following (amounts in thousands):
Total income tax expense differed from the “expected” income tax expense determined by applying the statutory federal income tax rate of 35% as follows (amounts in thousands):
The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities at December 31, 2013 and 2012 are summarized below (amounts in thousands):
At December 31, 2013, we have tax net operating loss carryforwards of $294.5 million that will begin expiring in 2020 if not utilized, and alternative minimum tax credit carryforwards of $1.9 million available to offset regular income taxes payable in future years. Our utilization of remaining acquired net operating loss carryforwards is subject to annual limitations pursuant to Internal Revenue Code section 382 which could reduce or defer the utilization of these losses.
Our tax net operating loss carryforwards are summarized below by year of expiration (amounts in thousands):
Tax benefits associated with recorded deferred tax assets are considered to be more likely than not realizable through taxable income earned in carryback years, future reversals of existing taxable temporary differences, and future taxable income exclusive of reversing temporary differences and carryforwards. The amount of deferred tax assets considered realizable, however, could be reduced if estimates of future taxable income during the carryforward period are reduced.
We file federal income tax returns in the U.S. and in various state jurisdictions. We are not subject to U.S. or state tax examinations by tax authorities for years 2009 and earlier except that certain U.S. federal income tax returns for years after 1998 are not closed by relevant statutes of limitations due to unused net operating losses reported on those income tax returns.
We recognize accrued interest on unrecognized tax benefits in interest expense and penalties in selling, general and administrative expenses. We did not have any unrecognized tax benefits as of December 31, 2013, 2012 and 2011, and accordingly, we did not recognize any interest expense. Additionally, we recorded no penalties during the years ended December 31, 2013, 2012 and 2011.
We did not record any excess tax benefit generated from stock options exercised during the years ended December 31, 2013, 2012 and 2011, since we are in a net operating loss carryforward position and the income tax deduction will not yet reduce income taxes payable. The cumulative excess tax benefits generated for stock options exercised that have not been recognized is $3.4 million at December 31, 2013.
