   Years Ended December 31,   2012 2011 2010 “Expected” statutory tax expense$ 7,437  4,500  6,215 State income taxes, net of federal  expense   1,770  1,141  1,129 Income tax effect of nondeductible  entertainment expenses  777  737  775 Income tax effect of nondeductible   lobbying expenses  298  327  405 Income tax effect of nondeductible officer  compensation  1,718  758  722 Other, net  88  (58)  2  $ 12,088  7,405  9,248
The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities at December 31, 2012and 2011are summarized below (amounts in thousands):
    2012 2011 Current deferred tax assets, net of current deferred tax liability:      Net operating loss carryforwards$ 3,952  7,796  Compensated absences, accrued for financial reporting  purposes  2,605  2,664  Workers compensation and self-insurance health reserves,  principally due to accrual for financial reporting purposes  1,357  1,068  Accounts receivable, principally due to allowance for doubtful  receivables  1,319  2,379  Deferred compensation expense for tax purposes in  excess of amounts recognized for financial reporting  purposes  32  131  Deferred revenue for financial reporting purposes  2,734  1,362  Other  898  155  Total current deferred tax assets$ 12,897  15,555        Long-term deferred tax assets:      Net operating loss carryforwards$ 116,034  119,762  Deferred revenue for financial reporting purposes  36,316  18,097  Alternative minimum tax credits  1,895  1,895  Deferred compensation expense for tax purposes in  excess of amounts recognized for financial reporting  purposes  2,543  2,581  Asset retirement obligations in excess of amounts recognized  for tax purposes  6,680  6,248  Share-based compensation expense for financial reporting  purposes in excess of amounts recognized for tax purposes  1,675  4,394  Other  3,353  469  Total long-term deferred tax assets  168,496  153,446        Long-term deferred tax liabilities:      Plant and equipment, principally due to differences in depreciation  233,530  211,172  Intangible assets  58,627  56,508  Total long-term deferred tax liabilities  292,157  267,680  Net long-term deferred tax liabilities$ 123,661  114,234
At December 31, 2012, we have tax net operating loss carryforwards of $293.3 million that will begin expiring in 2020 if not utilized, and alternative minimum tax credit carryforwards of $1.9million 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):
 Years ending December 31, Federal State 2020$ 43,863  42,768 2021  29,614  28,987 2022  14,081  13,788 2023  3,968  3,903 2024  722  - 2025  737  - 2026  150  - 2027  1,010  - 2028  39,879  39,715 2029  48,370  47,558 2031  110,933  109,376 Total tax net operating loss carryforwards$ 293,327  286,095
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 asset 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 no longer subject to U.S. or state tax examinations by tax authorities for years 2007 and earlier except that  certain U.S. federal income tax returns for years after 1997 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, 2012, 2011 and 2010, and accordingly, we did not recognize any interest expense.  Additionally, we recorded no penalties during the years ended December 31, 2012, 2011 and 2010.

 

We did not record any excess tax benefit generated from stock options exercised during the years ended December 31, 2012, 2011 and 2010, 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 $7.9 million at December 31, 2012. |
