Income Tax Disclosure [Abstract]
Income Taxes	(10) Income Taxes As of January 1, 2016, our unrecognized tax benefits were approximately $2 million. The amount, if recognized, that would affect the effective tax rate is approximately $1 million. During the quarter ended June 30, 2016, changes to the estimated liabilities for uncertain tax positions (including accrued interest) relating to tax positions taken during prior and current periods did not have a material impact on our financial statements. We recognize accrued interest and penalties associated with uncertain tax positions as part of the tax provision. As of June 30, 2016, we have less than $1 million of accrued interest and penalties. The U.S. federal statute of limitations remains open for the 2012 and subsequent years. Foreign and U.S. state and local jurisdictions have statutes of limitations generally ranging from 3 to 4 years. The statute of limitations on certain jurisdictions could expire within the next twelve months. It is reasonably possible that the amount of uncertain tax benefits will change during the next 12 months, however, it is anticipated that any such change, if it were to occur, would not have a material impact on our results of operations. We operate in multiple jurisdictions with varying tax laws. We are subject to audits by any of these taxing authorities. Our tax returns have been examined by the Internal Revenue Service (“IRS”) through the year ended December 31, 2006. We believe that adequate accruals have been provided for federal, foreign and state taxes.
