Income Tax Disclosure [Text Block]	8. Income taxes For the three months ended June 30, 2018, we recorded an income tax expense of $1.2 million on income before income taxes of $4.8 million, using an estimated effective tax rate for the fiscal year ending December 31, 2018 ( “Fiscal 2018” ) adjusted for certain minimum state taxes as well as the inclusion of a $0.2 million tax recovery related to ASU 2016 - 09, which requires all excess tax benefits and tax deficiencies related to employee share-based payments to be recognized through income tax expense. Comparatively, for the three months ended June 30, 2017, the Company recorded an income tax expense of $1.1 million on income before taxes of $6.3 million, using an estimated effective tax rate for the 2017 fiscal year and adjusted for the $1.2 million tax recovery impact related to ASU 2016 - 09. For the six months ended June 30, 2018, we recorded an income tax expense of $2.4 million on income before income taxes of $9.8 million, using an estimated effective tax rate for Fiscal 2018 adjusted for certain minimum state taxes as well as the inclusion of a $0.3 million tax recovery related to ASU 2016 - 09, which requires all excess tax benefits and tax deficiencies related to employee share-based payments to be recognized through income tax expense. Comparatively, for the six months ended June 30, 2017, the Company recorded income tax expense of $1.0 million on income before taxes of $8.6 million, using an estimated effective tax rate for the 2017 fiscal year and adjusted for the $2.2 million tax recovery impact related to ASU 2016 - 09. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. Management considers projected future taxable income, uncertainties related to the industry in which the Company operates, and tax planning strategies in making this assessment. The Company recognizes accrued interest and penalties related to income taxes in income tax expense. The Company did not have significant interest and penalties accrued at June 30, 2018 and December 31, 2017, respectively.
