(6) Income Taxes

Income taxes as a percentage of earnings before income taxes as reported in the consolidated financial statements were 27.3% for the three months ended June 30, 2012 compared to 32.0% for the three months ended June 30, 2011.

Income taxes as a percentage of earnings before income taxes as reported in the consolidated financial statements were 16.5% for the six months ended June 30, 2012 compared to 32.0% for the six months ended June 30, 2011. Excluding an immaterial correction of a prior period error of $371,000, income taxes as a percentage of earnings before income taxes were 30.6% in comparison to 32.0% for the six months ended June 30, 2012 and 2011, respectively.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not our Company will realize the benefits of these temporary differences at June 30, 2012 and, therefore, has not established a valuation reserve.
