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.

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 $1.1 million at June 30, 2011 and December 31, 2010 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 income for the three and six months ended June 30, 2011 and 2010. 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, 2011 and December 31, 2010, the Company had a total of $15.4 million and $18.1 million in gross unrecognized tax benefits, respectively. Of this amount, $9.9 million and $11.7 million represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate as of June 30, 2011 and December 31, 2010. Unrecognized tax benefits were a net decrease of approximately $1.6 million and $2.1 million during the quarters ended June 30, 2011 and June 30, 2010 due mainly to the expiration of certain statutes of limitation net of additions. Unrecognized tax benefits were a net decrease of $2.7 million and $3.2 million during the six months ended June 30, 2011 and 2010, 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 $7.6 million and $9.2 million at June 30, 2011 and December 31, 2010 and is included in income taxes payable per the consolidated balance sheet. Net interest and penalties included in income tax expense for the three month periods ended June 30, 2011 and 2010 was a benefit of approximately $0.8 million and $1.0 million, respectively. Net interest and penalties included in income tax expense for the six month periods ended June 30, 2011 and June 30, 2010 was a benefit of approximately $1.5 million and $1.8 million, respectively. There was a benefit to income tax expense during the three and six months periods ended June 30, 2011 and June 30, 2010 as penalties and interest accrued when the uncertain tax position was initially recorded, then reverse upon the expiration of certain statutes of limitations. 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:

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. As of June 30, 2011, the Company had received two intents from state agencies to perform examinations. 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 $0.7 million to $1.7 million during the next twelve months mainly due to the expiration of certain statute of limitations. The federal statute of limitations remains open for the years 2008 and forward. Tax years 2001 and forward are subject to audit by state tax authorities depending on the tax code and administrative practice of each state.
