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 nine months ended September 30, 2014 and 2013, 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 $3.3 million and $4.2 million income tax benefit for the three and nine months ended September 30, 2014, respectively, and $4.4 million and $7.4 million income tax benefit for the three and nine months ended September 30, 2013, respectively. We adopted the provisions of ASC 740-10 as of January 1, 2007 and determined that there were approximately $578,000 and $607,000 of unrecognized tax benefits required to be recorded as of September 30, 2014 and December 31, 2013, 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 nine months ended September 30, 2014 and 2013, 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 $3.3 million and $4.2 million income tax benefit for the three and nine months ended September 30, 2014, respectively, and $4.4 million and $7.4 million income tax benefit for the three and nine months ended September 30, 2013, respectively.

We adopted the provisions of ASC 740-10 as of January 1, 2007 and determined that there were approximately $578,000 and $607,000 of unrecognized tax benefits required to be recorded as of September 30, 2014 and December 31, 2013, respectively. We believe that the total amounts of unrecognized tax benefits will not significantly increase or decrease within the next 12 months.
