Note 3:  Income Taxes
 
No income tax expense was recognized for the three- and six-month periods ended June 30, 2014 and 2013, due to net losses being incurred in both periods. We are subject to audit by the IRS and various states for the prior three years. There has not been a change in our unrecognized tax positions since December 31, 2013, and we do not believe there will be any material changes in our unrecognized tax positions over the next 12 months. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We do not have any accrued interest or penalties associated with any unrecognized tax benefits, and no interest expense related to unrecognized tax benefits was recognized during the six months ended June 30, 2014.
