Income Taxes [Abstract]
Income Taxes	13. Income Taxes We, or one of our subsidiaries, file federal income tax returns in the United States and income tax returns in various states and foreign jurisdictions. With few exceptions, we are no longer subject to income tax examinations by any of the taxing authorities for years before 2006. There is currently one income tax examination in process. As of June 30, 2011, we have provided a liability of approximately $0.8 million of unrecognized tax benefits related to various federal and state income tax positions, which would impact our effective tax rate if recognized. We accrue penalties and interest related to unrecognized tax benefits through income tax expense, which is consistent with the recognition of these items in prior reporting periods. We had approximately $0.4 million accrued for the payment of interest and penalties at June 30, 2011, of which $0.2 million was accrued during the current year. Accrued interest and penalties are included in the $0.8 million of unrecognized tax benefits. During the current quarter, we did not release any tax reserves associated with items falling outside the statute of limitations and the closure of certain tax years for examination purposes. Events could occur within the next 12 months that would have an impact on the amount of unrecognized tax benefits that would be required. Approximately $2 thousand of unrecognized tax benefits relate to items that are affected by expiring statutes of limitation within the next 12 months.

13. Income Taxes

We, or one of our subsidiaries, file federal income tax returns in the United States and income tax returns in various states and foreign jurisdictions. With few exceptions, we are no longer subject to income tax examinations by any of the taxing authorities for years before 2006. There is currently one income tax examination in process.

As of June 30, 2011, we have provided a liability of approximately $0.8 million of unrecognized tax benefits related to various federal and state income tax positions, which would impact our effective tax rate if recognized.

We accrue penalties and interest related to unrecognized tax benefits through income tax expense, which is consistent with the recognition of these items in prior reporting periods. We had approximately $0.4 million accrued for the payment of interest and penalties at June 30, 2011, of which $0.2 million was accrued during the current year. Accrued interest and penalties are included in the $0.8 million of unrecognized tax benefits.
