Loss Contingency [Abstract]
Legal and Environmental Matters	Legal and Environmental Matters The Company is involved in litigation and claims incidental to our current and prior businesses. We provide accruals for such litigation and claims when payment is probable and reasonably estimable. We believe we have adequate accruals for continuing operations for all of our legal and environmental matters. We cannot estimate the aggregate possible range of loss for various reasons, including, but not limited to, many proceedings being in preliminary stages, with various motions either yet to be submitted or pending, discovery yet to occur and/or significant factual matters unresolved. In addition, most cases seek an indeterminate amount of damages and many involve multiple parties. Predicting the outcomes of settlement discussions or judicial or arbitral decisions is thus inherently difficult and future developments could cause these actions or claims, individually or in aggregate, to have a material adverse effect on the Company’s financial condition, results of operations or cash flows of a particular reporting period. We previously described certain legal proceedings in the Form 10-K. As of June 30, 2019, there were no material developments in those legal proceedings.
