Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES, ENVIRONMENTAL AND LEGAL MATTERS	CONTINGENCIES, ENVIRONMENTAL, AND LEGAL MATTERS Asset Retirement Obligations The Company has recognized AROs for properties where it can make a reasonable estimate of the future expenditures necessary to satisfy the related obligations. When calculating its ARO liability, the Company considers identified legally-enforceable obligations, estimated settlement dates and appropriate discount and inflation rates. The Company's ARO liability is included in the Consolidated Balance Sheets as "Accrued expenses and other current liabilities" and "Other liabilities" and totaled $22.3 million and $19.8 million at December 31, 2017 and 2016, respectively. Environmental Liabilities The Company is involved in various claims relating to environmental matters at a number of current and former plant sites and waste management sites. The Company engages or participates in remedial and other environmental compliance activities at certain of these sites. At other sites, it has been named as a potential responsible party pursuant to the federal Superfund Act and/or state Superfund laws comparable to the federal law for site remediation. The Company analyzes each individual site, considering the number of parties involved, the level of its potential liability or contribution relating to the other parties, the nature and magnitude of the hazardous wastes involved, the method and extent of remediation, the potential insurance coverage, the estimated legal and consulting expense with respect to each site, and the time period over which any costs would likely be incurred. Based on this analysis, the Company estimates the clean-up costs and related claims for each site. The estimates are based in part on discussions with other potential responsible parties, governmental agencies, and engineering firms. The Company accrues for environmental matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current laws and existing technologies. The accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. While uncertainty exists with respect to the amount and timing of its ultimate environmental liabilities, the Company does not currently anticipate any material losses in excess of the amount recorded. However, it is possible that new information about these sites, such as results of investigations, could make it necessary for the Company to reassess its potential exposure related to these environmental matters. The Company's environmental liability is included in the Consolidated Balance Sheets as "Accrued expenses and other current liabilities" and "Other liabilities," and totaled $28.3 million and $32.6 million at December 31, 2017 and 2016, respectively, primarily in connection with environmental remediation, clean-up costs, and monitoring of sites that were either closed or disposed of in prior years by Alent plc, which the Company acquired in December 2015. As of the date hereof, management does not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of the Company's recorded liabilities, and is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters. Legal Proceedings From time to time, the Company is involved in various legal proceedings in the normal course of its business. The Company believes that the resolution of these claims, to the extent not covered by insurance, will not individually or in the aggregate, have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows. In June 2009, a private lawsuit was filed in the District Court for the City of Ulianópolis in the State of Pará, Brazil against Arysta LifeScience do Brasil Industria Química e Agropecuária Ltda, or Arysta Brazil, and 25 other defendants in connection with materials sent by Arysta Brazil and others to an incineration site owned and operated by an unaffiliated third-party in the state of Pará, Brazil. In November 2011, the City of Ulianópolis also filed a claim in the District Court for the City of Ulianópolis, against Arysta Brazil and five other defendants on the same grounds. Arysta Brazil was summoned and has filed its answer in connection with both cases. Proceedings have been suspended indefinitely in order for the Pará State Attorney to determine the extent of contamination, the appropriate remediation, and the potentially responsible parties. Damages sought in the private lawsuit include a penalty of BRL 50.0 million ($15.1 million), plus interest and the cost of remediation. The cost of remediation in the case brought by the City of Ulianopolis was previously estimated by the City to be BRL 70.9 million ($21.4 million). In addition, in March 2014 and December 2015, an aggregate number of 29 former employees of the incineration facility brought actions in the Labor Court of Paragominas in the State of Pará, Brazil naming 80 defendants, including Arysta Brazil, seeking compensation in an aggregate amount of BRL 387 million ($117 million) for health problems allegedly contracted as a result of their employment at the incineration site. The Company is currently contesting several tax assessments in Brazil at various stages of the applicable administrative and judicial processes, with a combined amount at issue, including interest and penalties, of approximately BRL 90.6 million ($27.4 million). Brazil's tax regime is complex, and the administrative and judicial procedures for resolving disputed tax assessments are expensive and time-consuming. Because tax matters in Brazil historically take many years to resolve, it is very difficult to estimate when these matters will be finally resolved. Based on management's judgments, the Company does not expect it will incur a material loss in excess of accrued liabilities. As previously disclosed, MacDermid Printing has been involved in various lawsuits with DuPont and Cortron involving MacDermid Printing's flexographic printing technology and related business. On June 27, 2017, MacDermid Printing and DuPont reached an agreement to settle and dismiss all their respective lawsuits against each other, as well as MacDermid Printing's lawsuit against Cortron. In connection with the settlement, on July 14, 2017, DuPont made a payment of $20.0 million to MacDermid Printing, and the Company recorded a net settlement gain of $10.8 million in "Other (expense) income, net" in the Consolidated Statement of Operations. This settlement resolves all outstanding litigation between MacDermid Printing, DuPont, and Cortron. Proceeds from the settlement agreement are subject to the pending litigation provisions of the Business Combination Agreement and Plan of Merger dated as of October 10, 2013. In February 2015, MacDermid, as plaintiff, settled a litigation with Cookson Group plc, Enthone Inc., Cookson Electronics and David North, as defendants, for $25.0 million. The litigation related to certain corporate activities that occurred between MacDermid and the defendants in 2006 and 2007. On April 3, 2015, MacDermid received part of the settlement in the amount of $16.0 million and placed the remainder, net of legal costs, into escrow for future distribution in accordance with the pending litigation provisions of the Business Combination Agreement and Plan of Merger dated as of October 10, 2013.
