Accounting Policies [Abstract]
Recently adopted accounting standards	Recently Adopted Accounting Standards On January 1, 2019, we adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842).” See Note 4. Leases for further information regarding our adoption of ASC 842 and impacts to the financial statements. On January 1, 2019, we adopted FASB ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” See Note 8. Income Taxes for further information regarding our adoption of ASU 2018-02. For the quarter ended March 31, 2019, we have adopted the requirements in SEC Final Rule 33-10532 “Disclosure Updates and Simplification.” The adoption of this guidance resulted in presentation of the Consolidated Statements of Shareholders' Equity as part of our quarterly financial statements.
Commitments and contingencies	It is our policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that a liability has been incurred and the costs can be reasonably estimated. All accrued amounts have been recorded without giving effect to any possible future recoveries. Costs for ongoing environmental compliance, including maintenance and monitoring are expensed as incurred.
