Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation Imposto sobre Circulação de Mercadorias e Serviços, or ICMS, a form of value-added tax in Brazil, was assessed to our Brazilian subsidiary Schweitzer-Mauduit do Brasil Indústria e Comércio de Papel Ltda., or SWM-B, in December 2000. SWM-B received two assessments from the tax authorities of the State of Rio de Janeiro for unpaid ICMS taxes on certain raw materials from January 1995 through November 2000, collectively the Raw Materials Assessments. The Raw Materials Assessments concerned the accrual and use by SWM-B of ICMS tax credits generated from the production and sale of certain non-tobacco related grades of paper sold domestically that are immune from the tax to offset ICMS taxes otherwise owed on the sale of products that are not immune. SWM-B has contested the Raw Materials Assessments based on Article 150, VI of the Brazilian Federal Constitution of 1988, which grants immunity from ICMS taxes to papers intended for printing books, newspapers and periodicals, or immune papers, and thus to the raw material inputs used to produce immune papers. One of the two assessments, or Assessment 1 (case number 2001.001.115144-5), related in part to tax periods that predated our acquisition of the Pirahy mill in Pirai, Brazil. In October 2015, the Federal Supreme Court of Brazil denied the State’s appeal of Assessment 1, in the amount of approximately $16.0 million, a decision which is now final. The second assessment, or Assessment 2 (case number 2001.001.064544-6), pertains exclusively to periods during which SWM-B owned the Pirahy mill. Assessment 2 in the amount of approximately $13.2 million remains pending before the Federal Supreme Court of Brazil on SWM-B’s appeal on the merits and is likely to be finally decided by the action of the chamber of the court hearing the matter. No docket entry has been made yet regarding argument on Assessment 2. SWM-B received assessments from the tax authorities of the State of Rio de Janeiro, or the State, for unpaid ICMS and Fundo Estadual de Combate à Pobreza, or FECP, a value-added tax similar to ICMS, taxes on interstate purchases of electricity. The State issued three sets of assessments against SWM-B, one for May 2006 - November 2007, a second for January 2008 - December 2010, and a third for September 2011 - September 2013, collectively the Electricity Assessments. SWM-B has challenged all three Electricity Assessments in administrative proceedings before the State tax council (in the first-level court Junta de Revisão Fiscal and the appellate court Conselho de Contribuintes) based on Resolution 1.610/89, which defers these taxes on electricity purchased by an "electricity-intensive consumer." In October and November 2014, a majority of the Conselho de Contribuintes sitting en banc ruled against SWM-B in each of the first and second electricity assessments. The State issued notices to SWM-B to pay approximately $5.4 million in the first electricity assessment and $9.2 million in the second electricity assessment, based on the foreign currency exchange rate at September 30, 2017. SWM-B filed separate challenges to these electricity assessments in further court proceedings in the State judicial system, and different chambers of the judicial court granted SWM-B preliminary injunctions against enforcement. In March and July 2017, the first-level judicial court ruled that SWM-B must present additional evidence that it is an "electricity-intensive consumer" concerning the first and second electricity assessments. SWM-B is now pursuing these actions. SWM-B's challenge to the third electricity assessment (approximately $4.6 million as of September 30, 2017), was decided adversely to SWM-B at the first administrative level (Junta de Revisão Fiscal) and is now on appeal to the Conselho de Contribuintes. SWM-B believes that both the remaining Raw Materials Assessment and the Electricity Assessments will ultimately be resolved in its favor. No liability has been recorded in our consolidated financial statements for these assessments based on our evaluation of these matters under the facts and law as presently understood. The Company can give no assurance as to the ultimate outcome of such proceedings. In December 2016, the Conseil de Prud’hommes d’Orange (a French court dealing with labor matters) rendered a decision by which the Company’s wholly owned subsidiary, Schweitzer Mauduit France (“SWM France”), was ordered to pay approximately €1.3 million to 18 former employees of Malaucène Industries, another wholly owned subsidiary, on the grounds, among other things, that SWM France was a “co-employer” of the plaintiffs, and, as a result, liable for certain obligations of Malaucène Industries with respect to such employees. Malaucène Industries stopped production in 2009. The Company believes that SWM France, which is a corporate holding company and indirect corporate parent of Malaucène Industries, is not a “co-employer” of any person and that the other claims are also without merit. The Company has no liability recorded in the consolidated financial statements for this matter, believing that the chances of SWM France to reverse the decision on appeal are sufficient that no such reserve is warranted. There can be no assurance, however, that the court of appeals will decide in favor of SWM France on any of the questions pending before the court. Environmental Matters The Company's operations are subject to various nations' federal, state and local laws, regulations and ordinances relating to environmental matters. The nature of the Company's operations exposes it to the risk of claims with respect to various environmental matters, and there can be no assurance that material costs or liabilities will not be incurred in connection with such claims. While the Company has incurred in the past several years, and will continue to incur, capital and operating expenditures in order to comply with environmental laws and regulations, it believes that its future cost of compliance with environmental laws, regulations and ordinances, and its exposure to liability for environmental claims and its obligation to participate in the remediation and monitoring of certain hazardous waste disposal sites, will not have a material effect on its financial condition, results of operations or cash flows. However, future events, such as changes in existing laws and regulations (including the enforcement thereof), or unknown contamination of sites owned, operated or used for waste disposal by the Company (including contamination caused by prior owners and operators of such sites or other waste generators), or similar circumstances arising at our unconsolidated joint ventures, may give rise to additional costs which could have a material effect on the Company's financial condition or results of operations. General Matters In the ordinary course of its business activities, the Company and its subsidiaries are involved in certain other judicial, administrative and regulatory proceedings involving both private parties and governmental authorities. These proceedings include insured and uninsured regulatory, employment, general and commercial liability, environmental, intellectual property rights and other matters. At this time, the Company does not expect any of these proceedings to have a material adverse effect on its reputation, business, financial condition, results of operations or cash flows. However, as the outcomes of such proceedings are unpredictable, the Company can give no assurance that the results of any such proceedings will not materially affect its reputation, business, financial condition, results of operations or cash flows.

The Company's operations are subject to various nations' federal, state and local laws, regulations and ordinances relating to environmental matters. The nature of the Company's operations exposes it to the risk of claims with respect to various environmental matters, and there can be no assurance that material costs or liabilities will not be incurred in connection with such claims.

General Matters

In the ordinary course of its business activities, the Company and its subsidiaries are involved in certain other judicial, administrative and regulatory proceedings involving both private parties and governmental authorities. These proceedings include insured and uninsured regulatory, employment, general and commercial liability, environmental, intellectual property rights and other matters. At this time, the Company does not expect any of these proceedings to have a material adverse effect on its reputation, business, financial condition, results of operations or cash flows. However, as the outcomes of such proceedings are unpredictable, the Company can give no assurance that the results of any such proceedings will not materially affect its reputation, business, financial condition, results of operations or cash flows.
