Income Tax Disclosure [Abstract] |
Income Tax Disclosure [Text Block] | 9. Income Taxes For the three-month and nine-month periods ended September 30, 2014 and 2013, our income tax expense and effective income tax rates were as follows (dollars in thousands):
|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 30, |  |  | September 30, |
|  | 2014 |  |  | 2013 |  |  | 2014 |  |  | 2013 |
Income tax expense |  | $ | 8,608 |  |  | $ | 4,491 |  |  | $ | 10,343 |  |  | $ | 9,715 |
Effective income tax rate |  |  | 38.2 | % |  |  | 38.8 | % |  |  | 38.1 | % |  |  | 42.6 | %
We estimate our differences between taxable income or loss and recorded income or loss on an annual basis. Our tax provision for each quarter is based upon these full year projections, which are revised each reporting period. These projections incorporate estimates of permanent differences between U.S. GAAP income or loss and taxable income or loss, state income taxes and adjustments to our liability for unrecognized tax benefits to adjust our statutory Federal income tax rate of 35.0% to our effective income tax rate. For the nine-month period ended September 30, 2014, these estimates increased or decreased our statutory Federal income tax rate of 35.0% to our effective income tax rate of 38.1% as follows: state income taxes added 3.8%, while permanent differences between our U.S. GAAP income and taxable income resulted in a reduction of 0.5% and adjustments to our reserve for uncertain tax positions resulted in a reduction of 0.2%. For the nine-month period ended September 30, 2013, these estimates increased or decreased our statutory Federal income tax rate of 35.0% to our effective income tax rate of 42.6% as follows: an adjustment resulting from the expiration of certain unexercised stock options added 2.7%, state income taxes added 2.9%, permanent differences between our U.S. GAAP income and taxable income added 1.8%, an adjustment for the write off of stock options deferred under Section 162(m) of the internal revenue code added 0.6% and adjustments to our reserve for uncertain tax positions resulted in a reduction of 0.4%.
