Income Tax Disclosure [Abstract]
Income taxes	Income taxes The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate was approximately $11.4 million as of March 31, 2016 and $12.5 million as of December 31, 2015. The amount of accrued interest and penalties payable related to unrecognized tax benefits was $1.7 million as of March 31, 2016 and December 31, 2015. It is reasonably possible that the amount of unrecognized benefits with respect to certain of our unrecognized tax positions will increase or decrease within the next 12 months. These changes may be the result of settlement of ongoing audits, lapses of statutes of limitations or other regulatory developments. At this time, we estimate the amount of gross unrecognized tax positions may be reduced by up to approximately $2.8 million within the next 12 months primarily due to lapses of statutes of limitations and settlement of ongoing audits in various jurisdictions.
