Income Taxes [Abstract]
Income Taxes	Note 7. Income Taxes The income tax provision for interim periods is determined using an estimated annual effective tax rate adjusted for discrete items, if any, which are taken into account in the quarterly period in which they occur. We review and update our estimated annual effective tax rate each quarter. For the three and six months ended June 30, 2015 and 2014, our estimated annual effective tax rate was primarily impacted by the permanent item related to the noncash interest of our redeemable preferred stock. Accordingly, we recorded an approximately $0.5 million and $1.2 million income tax benefit for three and six months ended June 30, 2015, respectively, and $1.4 million and $0.9 million income tax benefit for the three and six months ended June 30, 2014, respectively. Under the provisions of ASC 740-10, we determined that there were approximately $715,000 and $708,000 of unrecognized tax benefits required to be recorded as of June 30, 2015 and December 31, 2014, respectively. We believe that the total amounts of unrecognized tax benefits will not significantly increase or decrease within the next 12 months.

Note 7. Income Taxes

The income tax provision for interim periods is determined using an estimated annual effective tax rate adjusted for discrete items, if any, which are taken into account in the quarterly period in which they occur. We review and update our estimated annual effective tax rate each quarter. For the three and six months ended June 30, 2015 and 2014, our estimated annual effective tax rate was primarily impacted by the permanent item related to the noncash interest of our redeemable preferred stock. Accordingly, we recorded an approximately $0.5 million and $1.2 million income tax benefit for three and six months ended June 30, 2015, respectively, and $1.4 million and $0.9 million income tax benefit for the three and six months ended June 30, 2014, respectively.

Under the provisions of ASC 740-10, we determined that there were approximately $715,000 and $708,000 of unrecognized tax benefits required to be recorded as of June 30, 2015 and December 31, 2014, respectively. We believe that the total amounts of unrecognized tax benefits will not significantly increase or decrease within the next 12 months.
