Income Tax Disclosure [Abstract] |
Income Tax Disclosure [Text Block] | Income Taxes Deferred income taxes are determined based upon the differences between the financial reporting and tax basis of the Company’s assets and liabilities. Deferred taxes are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense. The Company had recorded a valuation allowance of $0.2 million and $0.4 million at June 30, 2013 and December 31, 2012 related to the Company’s deferred tax asset associated specifically with unrealized losses on auction rate securities. This valuation allowance was recorded as the Company does not have historical capital gains nor does it expect to generate capital gains sufficient to utilize the entire deferred tax asset generated by the fair value adjustment. As the fair value adjustment was recorded through accumulated other comprehensive loss, the associated valuation allowance was also recorded through accumulated other comprehensive loss. The above mentioned allowance did not impact the consolidated statement of comprehensive income for the three and six months ended June 30, 2013 and 2012. The Company has not recorded a valuation allowance against any other deferred tax assets. In management’s opinion, it is more likely than not that the Company will be able to utilize these deferred tax assets in future periods as a result of the Company’s history of profitability, taxable income, and reversal of deferred tax liabilities. At June 30, 2013 and December 31, 2012, the Company had a total of $14.4 million and $15.7 million in gross unrecognized tax benefits, respectively. Of this amount, $9.2 million and $10.1 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of June 30, 2013 and December 31, 2012. Unrecognized tax benefits were a net decrease of $0.7 million, $0.7 million, $1.3 million and $1.5 million during the three and six months ended June 30, 2013 and 2012, respectively, due mainly to the expiration of certain statutes of limitation net of additions. This had the effect of reducing the effective state tax rate during these respective periods. The total net amount of accrued interest and penalties for such unrecognized tax benefits was $6.7 million and $7.4 million at June 30, 2013 and December 31, 2012 and is included in income taxes payable per the consolidated balance sheet. Net interest and penalties included in income tax expense for the three months and six months ended June 30, 2013 and 2012 was a benefit of approximately $0.3 million, $0.4 million, $0.7 million and $1.3 million, respectively. Income tax expense is increased each period for the accrual of interest on outstanding positions and penalties when the uncertain tax position is initially recorded. Income tax expense is reduced in periods by the amount of accrued interest and penalties associated with reversed uncertain tax positions due to lapse of applicable statute of limitations, when applicable or when a position is settled. Income tax expense was reduced during the three and six months ended June 30, 2013 and 2012 due to reversals of interest and penalties due to lapse of applicable statute of limitations, net of additions for interest and penalty accruals during the same periods. These unrecognized tax benefits relate to risks associated with state income tax filing positions for the Company’s corporate subsidiaries. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
| 2013
| (in thousands)
Balance at January 1, | $ | 15,723 |
Additions based on tax positions related to current year | 388 |
Additions for tax positions of prior years | 367 |
Reductions for tax positions of prior years | (51 | )
Reductions due to lapse of applicable statute of limitations | (1,984 | )
Settlements | — |
Balance at June 30, | $ | 14,443 |
A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. The Company does not have any outstanding litigation related to tax matters. At this time, management’s best estimate of the reasonably possible change in the amount of gross unrecognized tax benefits to be a decrease of approximately $0.2 million to $1.2 million during the next twelve months mainly due to the expiration of certain statute of limitations, net of additions. The federal statute of limitations remains open for the years 2010 and forward. Tax years 2003 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.
