Income Tax Disclosure [Abstract]
Income Taxes	Note 10 – Income Taxes As part of its 2014 Federal income tax return, the Company adopted the final IRS tangible property regulations and changed its accounting method for the tax treatment of expenditures that qualified as deductible repairs. The adoption resulted in a net reduction of $17.6 million in taxes previously remitted to the IRS, for which the Company has already sought and received the tax refunds. While the Company believes that its treatment of qualifying tangible property repair costs is proper, a reserve provision against refunded taxes of $2.3 million was recorded in 2015 at the time of filing its change in accounting method. This was based on a possible challenge by the IRS during an audit examination. The Company’s 2014 federal income tax return was subsequently selected for examination by the IRS in 2016. During the second quarter of 2018, the Company received information from the IRS regarding certain aspects of the its adopted accounting method used to calculate qualifying tangible property repair cost deductions and has determined that it should increase its reserve provision to $3.7 million. As the IRS examination continues and pending its completion, the tax liability could be different than the recorded reserve provision. For the three and six months ended June 30, 2018, the Company has recorded $0.4 million in interest expense due to this reserve provision.

Note 10 – Income Taxes

As part of its 2014 Federal income tax return, the Company adopted the final IRS tangible property regulations and changed its accounting method for the tax treatment of expenditures that qualified as deductible repairs. The adoption resulted in a net reduction of $17.6 million in taxes previously remitted to the IRS, for which the Company has already sought and received the tax refunds. While the Company believes that its treatment of qualifying tangible property repair costs is proper, a reserve provision against refunded taxes of $2.3 million was recorded in 2015 at the time of filing its change in accounting method. This was based on a possible challenge by the IRS during an audit examination. The Company’s 2014 federal income tax return was subsequently selected for examination by the IRS in 2016. During the second quarter of 2018, the Company received information from the IRS regarding certain aspects of the its adopted accounting method used to calculate qualifying tangible property repair cost deductions and has determined that it should increase its reserve provision to $3.7 million. As the IRS examination continues and pending its completion, the tax liability could be different than the recorded reserve provision. For the three and six months ended June 30, 2018, the Company has recorded $0.4 million in interest expense due to this reserve provision.
