General	General
	Nature of Business
	Schweitzer-Mauduit International, Inc., or SWM or the Company, is a multinational diversified producer of premium specialty papers and plastic nettings headquartered in the United States of America. The Company manufactures and sells paper and reconstituted tobacco products to the tobacco industry as well as specialized paper products for use in other applications. We manufacture lightweight specialty papers, which are used in manufacturing ventilated cigarettes, and banded papers for the production of lower ignition propensity, or LIP, cigarettes and are the leading independent producer of RTL used in producing blended cigarettes. We also manufacture resin-based plastic netting through an extrusion process, as well as certain meltblown products and machined plastic core tubes.
	Our primary products sold to the tobacco industry include cigarette, plug wrap and base tipping papers, or Cigarette Papers, used to wrap various parts of a cigarette and reconstituted tobacco leaf, or RTL, which is used as a blend with virgin tobacco in cigarettes, reconstituted tobacco wrappers and binders for cigars. These products are sold directly to the major tobacco companies or their designated converters in the Americas, Europe, Asia and elsewhere. Our non-tobacco industry products are a diverse mix of products that includes low volume, high-value engineered papers as well as commodity paper grades produced to maximize our machine utilization. In December 2013, we acquired DelStar, Inc. ("DelStar"), a manufacturer of plastic netting and other resin-based products focused on the filtration and medical markets. In December 2014, we acquired certain assets from Pronamic Industries, Inc., or Pronamic, and from Smith & Nephew's, or SNN, Advanced Wound Management Division which have been incorporated into our Filtration operating segment.
	We conduct business in over 90 countries and operate 16 production locations worldwide, with facilities in the United States, Canada, United Kingdom, France, Luxembourg, Russia, Brazil, China and Poland. We also have a 50% equity interest in two joint ventures in China. The first, China Tobacco Mauduit (Jiangmen) Paper Industry Ltd., or CTM, produces cigarette and porous plug wrap papers and the second, which began operations in the third quarter of 2014, China Tobacco Schweitzer (Yunnan) Reconstituted Tobacco Co. Ltd., or CTS, which produces RTL.
	As used in this 2014 Annual Report on Form 10-K, unless the context indicates otherwise, references to "we," "us," "our," "SWM," "Schweitzer-Mauduit" or similar terms include Schweitzer-Mauduit International, Inc. and its consolidated subsidiaries.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated financial statements and the notes thereto have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. The Company believes the estimates and assumptions used in the preparation of these consolidated financial statements are reasonable, based upon currently available facts and known circumstances. Actual results may differ from those estimates and assumptions as a result of a number of factors, including those discussed elsewhere in this report and in its other public filings from time to time.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and wholly-owned, majority-owned and controlled subsidiaries. Intercompany balances and transactions have been eliminated.
	The Company has two joint ventures with China National Tobacco Corporation, or CNTC. CNTC is the principal operating Company under China's State Tobacco Monopoly Administration. CNTC and our subsidiary, SM-China, each own 50% of the joint ventures. The paper joint venture China Tobacco Mauduit (Jiangmen) Paper Industry Co. LTD, or CTM, produces tobacco-related papers in China. The second joint venture China Tobacco Schweitzer (Yunnan) Reconstituted Tobacco Co. LTD., or CTS, produces reconstituted tobacco leaf products. The Company uses the equity method to account for both joint ventures. Investment in equity affiliates represents the Company's investment in its China joint ventures. The Company's share of the net income of its 50% owned joint ventures in China are included in the consolidated statements of income as income from equity affiliates.
	Revenue Recognition
	The Company recognizes revenue and the related accounts receivable when the following four criteria are met: (1) persuasive evidence of an arrangement exists; (2) ownership has transferred to the customer; (3) the selling price is fixed or determinable; and (4) collection is reasonably assured based on the Company's judgment regarding the collectability of its accounts receivable. Generally, the Company recognizes revenue when it ships its manufactured product and title and risk of loss passes to its customer in accordance with the terms of sale of the product. Revenue is recorded at the time of shipment for terms designated f.o.b., or free on board, shipping point. For sales transactions designated f.o.b. destination, revenue is recorded when the product is delivered to the customer's delivery site, at which time title and risk of loss are transferred. Provisions for discounts, returns, allowances, customer rebates and other adjustments are provided for in the same period the related revenue is recorded. Deferred revenue represents advance payments from customers which are earned based upon a mutually agreed-upon amount per unit of future product sales.
	Freight Costs
	The cost of delivering finished goods to the Company's customers is recorded as a component of cost of products sold. Those costs include the amounts paid to a third party to deliver the finished goods. Any freight costs billed to and paid by a customer are included in revenue.
	Royalty Income
	Royalties from non-exclusive, third-party patent licenses are recognized when earned, including monies received at an agreement's initiation attributable to past sales. The Company recognizes up-front payments upon receipt when it has no future performance requirement or ongoing obligation arising from its agreements and the payment is for a separate earnings process. Minimum annual royalties received in advance are deferred and are recognized in the period earned. The Company recognized $11.1 million, $11.2 million and $12.4 million of royalty income during 2014, 2013 and 2012 respectively, which is included in net sales in the consolidated statements of income.
	Foreign Currency Translation
	The income statements of foreign entities are translated into U.S. dollars at average exchange rates prevailing during the periods presented. The balance sheets of these entities are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in a separate component of accumulated other comprehensive income (loss) as unrealized foreign currency translation adjustments.
	Foreign currency risks arise from transactions and balances denominated in non-local currencies. Gains and losses resulting from re-measurement and settlement of such transactions and balances, included in other income (expense), net, were gain of $1.5 million and $1.3 million in 2014 and 2013, respectively, and loss of $1.4 million in 2012.
	Derivative Instruments
	The Company is exposed to changes in foreign currency exchange rates, interest rates and commodity prices. The Company utilizes a variety of practices to manage these market risks, including where considered appropriate, derivative instruments. The Company uses derivative instruments only for risk management purposes and not for trading or speculation. All derivative instruments the Company uses are either exchange traded or are entered into with major financial institutions in order to reduce credit risk and risk of nonperformance by third parties. The Company believes the credit risks with respect to the counterparties, and the foreign currency risks that would not be hedged if the counterparties fail to fulfill their obligations under the contracts, are not material in view of its understanding of the financial strength of the counterparties.
	Gains and losses on instruments that hedge firm commitments are deferred and included in the basis of the underlying hedged items. All other hedging gains and losses are included in period income or expense based on the period-end market price of the instrument and are included in the Company's operating cash flows. See Note 13. Derivatives, for additional information.
	Cash and Cash Equivalents
	The Company considers all highly liquid, unrestricted investments with remaining maturities of three months or less to be cash equivalents, including money market funds with no restrictions on withdrawals.
	Business Combinations
	The Company uses the acquisition method of accounting for business combinations. At the acquisition date, the Company records assets acquired and liabilities assumed at their respective fair market values. The Company estimates fair value using the exit price approach which is the price that would be received to sell an asset or paid to transfer a liability in an orderly market. An exit price is determined from a market participant's viewpoint in the principal or most advantageous market and may result in the Company valuing assets or liabilities at a fair value that is not reflective of the Company's intended use of the assets or liabilities. Any excess consideration above the estimated fair values of the net assets acquired is recognized as goodwill on the Company's Consolidated Balance Sheets. The operating results of acquired businesses are included in the Company's results of operations beginning as of their effective acquisition dates. Acquisition costs are expensed as incurred and were $2.6 million and $1.1 million in 2014 and 2013, respectively, and were not material in 2012.
	Impairment of Long-Lived Assets, Goodwill and Intangible Assets
	The Company evaluates the carrying value of long-lived assets, including property and equipment, goodwill and intangible assets when events and circumstances warrant a review. Goodwill is also tested for impairment annually during the fourth quarter. Goodwill may be evaluated using a qualitative evaluation and/or a two-step test at the reporting unit level. The first step compares the book value of the reporting unit to its fair value. If the book value of a reporting unit exceeds its fair value, we perform the second step. In the second step, we determine an implied fair value of the reporting unit's goodwill by allocating the fair value of the reporting unit to all of the assets and liabilities other than goodwill. The difference between the total fair value of the reporting unit and the fair value of all the assets and liabilities other than goodwill is the implied fair value of that goodwill. Any impairment loss is measured as the excess of the book value of the goodwill over the implied fair value of that goodwill. See Note 8. Goodwill for further discussion of the Company's annual impairment test results.
	We have acquired trade names that have been determined to have indefinite lives. We evaluate a number of factors to determine whether an indefinite life is appropriate, including the competitive environment, category share, business history, product life cycle and operating plans. Indefinite-lived intangibles are evaluated for impairment annually during the fourth quarter. Additionally, when certain events or changes in operating conditions occur, an impairment assessment is performed and indefinite-lived trade names may be adjusted to a determinable life or an impairment charge may be recorded.
	The cost of intangible assets with determinable useful lives is amortized to reflect the pattern of economic benefits consumed, which approximates a straight-line basis, over the estimated periods benefited. When certain events or changes in operating conditions occur, an impairment assessment is performed and lives of intangible assets with determinable lives may be adjusted.
	The carrying value of long-lived assets is reviewed to determine if events or circumstances have changed which may indicate that the assets may be impaired or the useful life may need to be changed. Upon occurrence of such a triggering event, the Company considers internal and external factors relating to each asset group, including expectation of future profitability, undiscounted cash flows and its plans with respect to the operations. If impairment is indicated, an impairment loss is measured by the amount the net carrying value of the asset exceeds its estimated fair value.
	Environmental Spending
	Environmental spending is capitalized if such spending qualifies as property, plant and equipment, substantially increases the economic value or extends the useful life of an asset. All other such spending is expensed as incurred, including fines and penalties incurred in connection with environmental violations. Environmental spending relating to an existing condition caused by past operations is expensed. Liabilities are accrued when environmental assessments are probable and the costs can be reasonably estimated. Generally, timing of these accruals coincides with completion of a feasibility study or commitment to a formal plan of action.
	Capitalized Software Costs
	The Company capitalizes certain purchases of software and software development costs in connection with major projects of software development for internal use. These costs are included in other assets on the consolidated balance sheets and are amortized using the straight-line method over the estimated useful life not to exceed seven years. Costs associated with business process redesign, end-user training, system start-up and ongoing software maintenance are expensed as incurred. Amortization of capitalized software was $3.4 million, $4.8 million and $6.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. Accumulated amortization of capitalized software costs was $60.5 million and $60.9 million at December 31, 2014 and 2013, respectively.
	Business Tax Credits
	Business tax credits represent value added tax credits receivable and similar assets, such as Imposto sobre Circulação de Mercadorias e Serviços, or ICMS, in Brazil. Business tax credits are generated when value-added taxes, or VAT, are paid on purchases. VAT and similar taxes are collected from customers on certain sales. In some jurisdictions, export sales do not require VAT collection. See Note 10. Other Assets for additional information.
	Income Taxes
	The Company uses an asset and liability approach to account for and report income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense (benefit) is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. Valuation allowances are recognized to reduce deferred tax assets to the amount that is more likely than not to be realized. In assessing the likelihood of realization, the Company considers sources of future taxable income.
	In connection with income tax assessments or unrecognized tax benefits, the Company classifies penalties as provision for income taxes and interest as interest expense in its consolidated statements of income.
	The Company files income tax returns in the U.S. Federal and several state jurisdictions as well as in many foreign jurisdictions. In France, the Company reorganized its legal entities to maximize utilization of its net operating loss carryforwards. With certain exceptions, the Company is no longer subject to U.S. Federal, state and local, or foreign income tax examinations for years before 2011.
	Pension and Other Postretirement Benefits Accounting
	The Company recognizes the estimated compensation cost of employees' pension and other postretirement benefits over their approximate period of service. The Company's earnings are impacted by amounts of expense recorded related to these benefits, which primarily consist of U.S. and French pension benefits and U.S. other postretirement benefits, or OPEBs. Each year's recorded expenses are estimates based on actuarial calculations of the Company's accumulated and projected benefit obligations, or PBOs, for the Company's various plans.
	Suspension of additional benefits for future service is considered a curtailment, and if material, necessitates a re-measurement of plan assets and PBO. As part of a re-measurement, the Company adjusts its discount rates and other actuarial assumptions, such as retirement, turnover and mortality table assumptions, as appropriate. See Note 16. Postretirement and Other Benefits for additional information.
	Comprehensive Income
	Comprehensive income includes net income, as well as items charged and credited directly to stockholders' equity, which are excluded from net income. The Company has presented comprehensive income in the consolidated statements of comprehensive income (loss). Reclassification adjustments of derivative instruments are presented in Net Sales in the consolidated statements of income. See Note 13. Derivatives for additional information. Amortization of accumulated pension and other post-employment benefit (OPEB) liabilities are included in the computation of net periodic pension and OPEB costs, which are more fully discussed in Note 16. Postretirement and Other Benefits.
	Components of accumulated other comprehensive loss were as follows ($ in millions):

	Restricted Stock
	All of the Company's restricted stock grants, including those that have been earned in the case of performance-based shares and cliff-vesting grants that are not performance based, vest upon completion of a specified period of time. The fair value of each award is equal to the share price of the Company's stock on the date of the grant. This cost is recognized over the vesting period of the respective award. A summary of outstanding restricted stock awards as of December 31, 2014 and 2013 is included in Note 17, Stockholders' Equity.
	Restricted Stock Plan Performance Based Shares
	The Company's long-term incentive compensation program, or LTIP, for key employees includes an equity-based award component that is provided through its Restricted Stock Plan, or RSP. The objectives under the LTIP are established for the immediate following year at the beginning of a performance cycle and are intended to focus management on longer-term strategic goals. The Compensation Committee of the Board of Directors designates participants in the LTIP and RSP and determines the equity-based award opportunity in the form of restricted stock for each performance cycle, which is generally measured on the basis of a one or two-year performance period. Performance is measured on a cumulative basis and each performance cycle's restricted stock award opportunity is earned annually. The restricted shares are considered issued and outstanding when the number of shares becomes fixed, after the annual performance is determined, and such awards vest at the end of the performance cycle or some predetermined period thereafter. The Company recognizes compensation expense with an offsetting credit to additional paid-in-capital over the performance period based on the fair value of the award at the date of grant, with compensation expense being adjusted cumulatively based on the number of shares expected to be earned according to the level of achievement of performance goals.
	Fair Value Option
	The Company has elected not to measure its financial instruments or certain commitments at fair value.
Recent Accounting Pronouncements
In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-08 (ASU 2014-08) "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. The Company adopted this guidance as of January 1, 2015. Adoption of ASU 2014-08 did not have an impact on our consolidated financial statements.
In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" (Topic 606). The new guidance specifies how and when an entity will recognize revenue arising from contracts with customers and requires entities to disclose information about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The guidance is effective for annual periods beginning on or after December 15, 2016 and may be implemented using a full retrospective or a modified retrospective application. The Company is currently in the process of evaluating the impact the adoption will have on our consolidated financial statements.
In June 2014, the FASB issued Accounting Standard Update ("ASU") No 2014-12, "Compensation - Stock Compensation: Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. Compensation cost should be recognized in the period in which it becomes probably that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The amendment is effective for annual reporting periods including interim reporting within those periods beginning after December 15, 2015. Earlier adoption is permitted. The Company is currently in the process of evaluating the impact the adoption will have on our consolidated financial statements.
In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements-Going Concern" (Subtopic 205-40). The Update provides U.S. GAAP guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. This update is effective for annual periods ending after December 15, 2016 and interim periods thereafter. Early adoption is permitted. The Company adopted this guidance as of December 31, 2014. Adoption of ASU 2014-15 did not have an impact on our consolidated financial statements.
In November 2014, the FASB released Accounting Standards Update (ASU) 2014-17, "Business Combinations (Topic 805): Pushdown Accounting, a consensus of the FASB Emerging Issues Task Force. This ASU amends FASB Accounting Standards Codification (FASB ASC) 805, Business Combinations", to provide guidance on whether and at what threshold an acquired entity that is a business or not-for-profit (NFP) entity can apply pushdown accounting in its separate financial statements. The amendments in this ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The amendments in this ASU are effective on November 18, 2014, or upon issuance. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. The Company adopted this guidance as of December 31, 2014. Adoption of ASU 2014-17 did not have a material impact on our consolidated financial statements.
In November 2014, the FASB issued ASU 2014-16, "Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity." The update requires an entity to determine the nature of the host contract by considering all stated and implied substantive terms and features of the hybrid financial instrument, weighing each term and feature on the basis of the relevant facts and circumstances (commonly referred to as the whole-instrument approach). This guidance is effective for annual periods beginning after December 15, 2015, and interim periods thereafter. Early adoption is permitted. The Company is currently in the process of evaluating the impact the adoption will have on our consolidated financial statements.

Business_Acquisitions

Business Acquisitions	12 Months Ended
	Dec. 31, 2014
Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions
	In December 2014, the Company acquired certain assets from Pronamic Industries, Inc., or Pronamic and Smith & Nephew, or SNN. As a result of the acquisition, these assets were incorporated into SWM's Filtration segment. The acquisition of these assets provides further opportunities for growth into the filtration and healthcare industries. These acquisitions are being treated as business combinations and accounted for in accordance with the guidance provided by ASC 805, Business Combinations. The purchase price included initial cash payments of $30.7 million, net of $0.7 million in working capital adjustments. An additional variable payment of up to $3.5 million may be due based on the performance of the assets over a period from the acquisition date through December 31, 2015. An additional $1.0 million payable was recorded based on management's estimate of the fair value of the variable consideration payable.
	As of December 31, 2014, the fair values of the assets acquired and liabilities assumed for the acquisition of assets from Pronamic and SNN are provisional because final appraisals have not yet been completed. The cash paid for these acquisitions and the preliminary fair values of the assets acquired and liabilities assumed as of the December 19, 2014 and December 31, 2014 acquisition dates for Pronamic assets and SNN assets, respectively, are as follows ($ in millions):
		Preliminary Fair Value as Acquisition Date
	Accounts receivable	$	3.5
	Inventory	3.2
	Other current assets	0.2
	Property, plant and equipment	9.3
	Identifiable intangible assets	11.6
	Total Assets	27.8
	Accounts payable	1.4
	Accrued expenses	1.4
	Net assets acquired	25
	Goodwill	5
	Cash paid	$	30
	The Company used the income, market, or cost approach (or a combination thereof) for the preliminary valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions. Market participants are considered to be buyers and sellers in the principal or most advantageous market for the asset or liability. For certain items, the carrying amount was determined to be a reasonable approximation of fair value based on information available to SWM management.
	Properties acquired included two manufacturing and related facilities, land and leased sites that include leasehold improvements, and machinery and equipment for use in manufacturing operations. Management valued properties using the cost approach supported where available by observable market data which included consideration of obsolescence.
	Intangible assets acquired included contracts with significant customers, technology related to products subject to a number of existing patents and trade know-how, and a number of customer relationships in water filtration, industrial filtration and healthcare industries. Management valued intangible assets using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data for peer companies. The following table shows the preliminary fair values assigned to intangible assets ($ in millions):
		Preliminary		Weighted-Average Amortization Period (Years)
		Fair Value as of December 31, 2014
	Amortizable intangible assets:
	Customer relationships	$	6.1	15
	Developed Technology	2.1		20
	Patents	1.5		17
	Customer contracts	1.9		6
	Total	$	11.6	15
	In connection with the acquisitions, the Company recorded goodwill, which represents the excess of the consideration transferred over the estimated preliminary fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to incremental revenue growth from combining the acquired assets with DelStar's existing business and workforce as well as the benefits of access to different markets and customers. Goodwill from these acquisitions will be assigned to the Filtration segment. None of the goodwill is expected to be deductible for tax purposes.
	The goodwill was determined on the basis of the provisional fair values of the assets and liabilities identified as of the acquisition date. It may be adjusted, within a period of no more than 12 months from the acquisition date, if the provisional fair values change as a result of circumstances existing at the acquisition date. Such fair value adjustments may arise in respect to property, plant and equipment, intangible assets and inventories, upon completion of the necessary valuations and physical verifications of such assets. The amount of provisions may also be adjusted as a result of ongoing procedures to identify and measure liabilities and contingent liabilities, including tax, environmental risks and litigation. The amount of deferred taxes may also be adjusted during the measurement period.
	In 2014, the Company recognized $1.3 million in direct and indirect acquisition-related costs related to the acquisitions. Direct and indirect acquisition-related costs were expensed as incurred and are included in the General Expense line item in the Consolidated Statements of Income.
	The amounts of the combined acquisitions' Net Sales and Income from Continuing Operations included in the Company's Consolidated Statements of Income for the year ended December 31, 2014, and the unaudited pro forma Net Sales and Income from Continuing Operations of the combined entity had the acquisition date been January 1, 2013, including the proforma 2013 and actual 2014 results of DelStar, are as follows ($ in millions):
			Net Sales	(Loss) Income from Continuing Operations
	Actual from December 19, 2014 - December 31, 2014		0.2	(0.4	)
	2014 Supplemental Pro Forma from January 1, 2014 - December 31, 2014		823.6	92.4
	2013 Supplemental Pro Forma from January 1, 2013 - December 31, 2013		904.3	86.4
	On December 12, 2013, the Company completed the acquisition of DelStar, Inc., or DelStar, through a merger of SWM Acquisition Corp. II, an indirect wholly-owned subsidiary of the Company, or SWM II, with and into DelStar, pursuant to the November 18, 2013 Agreement and Plan of Merger. As a result of the merger, DelStar became a wholly-owned, indirect subsidiary of the Company. The acquisition of DelStar diversified SWM's global presence in advanced materials, focused in large part in filtration.
	As consideration, the Company paid $233.7 million in cash, including $2.4 million paid in March 2014, primarily for the adjusted value of working capital at the acquisition date. The acquisition was financed using borrowings under the revolving credit facility, or Credit Agreement, see Note 12. Debt, for additional information.
	The consideration paid for DelStar and the final fair values of the assets acquired and liabilities assumed as of the December 12, 2013 acquisition date are as follows ($ in millions):
		Fair value as of December 12, 2013
	Cash and cash equivalents	$	1.6
	Accounts receivable	17.3
	Inventory	21.2
	Income taxes receivable	5.7

	The Company used the income, market, or cost approach (or a combination thereof) for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions. Market participants are considered to be buyers and sellers in the principal or most advantageous market for the asset or liability. For certain items, the carrying amount was determined to be a reasonable approximation of fair value based on information available to SWM management. The fair value of receivables acquired from DelStar on December 12, 2013 was $17.3 million, with gross contractual amounts receivable of $17.6 million. Acquired inventories and property, plant and equipment were recorded at their fair values. Acquired intangible assets are primarily trade names, customer relationships and developed technology.
	Properties acquired included a number of manufacturing and related facilities, land and leased sites that include leasehold improvements, and machinery and equipment for use in manufacturing operations. Management valued properties using the cost approach supported where available by observable market data which included consideration of obsolescence.
	Intangible assets acquired included a number of trade names that are both business-to-business and business-to-consumer. Also acquired was technology related to products subject to a number of existing patents and trade know-how. In addition to these intangible assets, the Company acquired a number of customer relationships in water filtration, industrial filtration and healthcare industries. Management valued intangible assets using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data for peer companies. The following table shows the fair values assigned to intangible assets ($ in millions):
		Fair Value as of December 12, 2013		Weighted-Average Amortization Period (Years)
	Amortizable intangible assets:
	Customer relationships	$	45.3	23
	Developed Technology	13.8		12.8
	Indefinite-lived intangible assets:
	Trade names	21.8		Indefinite
Total	$	80.9	21
In connection with the acquisition, the Company recorded goodwill, which represents the excess of the consideration transferred over the estimated preliminary fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to DelStar's revenue growth from combining the SWM and DelStar business and workforce as well as the benefits of access to different markets and customers. Goodwill from the DelStar acquisition was assigned to its own reportable segment Filtration. None of the goodwill is expected to be deductible for tax purposes. The goodwill was determined on the basis of the final fair values of the assets and liabilities identified as part of the transaction.
In 2014 and 2013, the Company recognized $1.3 million and $1.1 million, respectively, in direct and indirect acquisition-related costs. In 2013, the Company incurred $2.0 million in financing costs related to the acquisition. Direct and indirect acquisition-related costs were expensed as incurred and are included in the General Expense line item in the Consolidated Statements of Income. Financing costs related to expanding the Credit Agreement have been capitalized and will be amortized in Interest Expense over the life of the Credit Agreement.

	The Company's former paper mill in Medan, Indonesia and closed paper mill in San Pedro, Philippines have been reported as discontinued operations. The sale of the Indonesia mill was finalized in the second quarter of 2013 and a $1.6 million non-cash loss was recorded in discontinued operations. The sale of the Philippines mill was finalized in the fourth quarter of 2013 and resulted in a gain of $1.6 million. For all periods presented, results of these mills have been removed from each individual line within the statements of income and the operating activities section of the statements of cash flow. In each case, a separate line has been added for the net results of discontinued operations.

	Inventories are valued at the lower of cost using the First-In, First-Out, or FIFO, and weighted average methods, or market. The Company's costs included in inventory primarily consist of pulp, chemicals, direct labor, utilities, maintenance, depreciation, finishing supplies and an allocation of mill overhead costs. Machine start-up costs or abnormal machine shut downs are expensed in the period incurred and are not reflected in inventory. The definition of market value, with respect to all inventories, is replacement cost or net realizable value. The Company reviews inventories at least quarterly to determine the necessity of write-offs for excess, obsolete or unsalable inventory. The Company estimates write-offs for inventory obsolescence and shrinkage based on its judgment of future realization. These reviews require the Company to assess customer and market demand.

Restructuring and Impairment Activities	Restructuring and Impairment Activities
	The Company incurred restructuring and impairment expenses of $13.1 million, $41.3 million and $21.4 million in the years ended December 31, 2014, 2013 and 2012, respectively.
	In the Paper segment, restructuring and impairment expenses were $4.5 million, $2.4 million and $17.9 million during the years ended December 31, 2014, 2013 and 2012, respectively. During 2014, restructuring and impairment expenses primarily included $2.6 million related to severance expenses in the French, Brazilian and U.S. operations for ongoing accruals over the remaining service lives of affected employees related to previously announced actions as well as losses on disposal of our Lee Mills and Golden Hills manufacturing facilities of $1.0 million and asset impairment expenses at our Canada manufacturing facility of $0.9 million. During 2013, restructuring and impairment expenses primarily included $1.6 million related to severance and early retirement expenses in the French operations for ongoing accruals over the remaining service lives of affected employees related to new as well as previously announced actions and terminating a third-party printing agreement in Europe. During 2012, expenses for the Paper segment were primarily related to the Company's amendment of a supply agreement with Philip Morris-USA, a subsidiary of Altria Group Inc. The amended agreement eliminated the Company's contractual commitment to stand ready to produce commercial quantities of banded cigarette paper even in the absence of firm orders. The Company considered these new terms to be a triggering event requiring evaluation of the recoverability of our Spotswood mill's banded cigarette paper production assets. Based on this analysis, which reflected management's assessment of the most likely future utilization of the mill, the Company in 2012 recorded a $16.9 million impairment charge to reduce the carrying value of these assets to their fair value.
	The Reconstituted Tobacco segment restructuring and impairment expenses were $6.8 million, $38.6 million and $4.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Restructuring expenses incurred in 2014 related to severance expenses in the French operations for ongoing accruals over the remaining service lives of affected employees related to new as well as previously announced actions. During 2013 and 2012, the Company recorded $37.2 million and $3.1 million, respectively, of impairment expenses related to the Company's RTL facility in the Philippines. In January 2011, the Company learned of decreased RTL needs of a major customer and suspended construction of the RTL facility. The Company conducted an impairment analysis at each reporting period on the mothballed assets. At the end of 2013, the Company's estimates of near-term, cyclical RTL demand decreased such that cash flows from the potential restart of the facility were weighted less in management's assessment of the most likely future operation of the site. The 2013 charge reduced the carrying value of these assets, primarily construction-in-progress, to their fair value at December 31, 2013.
	Fair value of the RTL Philippines facility and the Spotswood, New Jersey mill was determined by using management's estimates of market participants' discounted future cash flows and independent appraisals of certain assets, both which are considered significant unobservable inputs, or Level 3 inputs. Management used significant judgment to develop assumptions, including forecasted sales volumes, allocation of certain overhead costs attributable to the Spotswood mill and weighted average cost of capital, based on historical and projected operational performance.
	Remaining restructuring expense for the Reconstituted Tobacco segment for the years ended December 31, 2013 and 2012 related to severance expenses in the French operations for ongoing accruals over the remaining service lives of affected employees related to previously announced actions.
	The Filtration segment restructuring expenses were $0.4 million in 2014 and $0 in 2013 and 2012. The expenses incurred in 2014 related to severance expenses incurred during the acquisition of the assets from SNN in December 2014.
	Additionally, the Company incurred $1.4 million in restructuring expenses related to accruals for severance expenses within supporting overhead departments during 2014 which were not allocated to a specific segment.
	Restructuring liabilities were classified within Accrued expenses in each of the consolidated balance sheets as of December 31, 2014 and 2013. Changes in the restructuring liabilities, substantially all of which are employee-related, are summarized as follows ($ in millions):

	Credit Agreement
	In December 2013, the Company amended and restated its unsecured revolving credit facility, or Credit Agreement. The five-year revolving Credit Agreement provides for borrowing capacity of $500.0 million in either U.S. Dollars or a $300.0 million equivalent sublimit in euros with an option to increase borrowing capacity by $200 million. The Credit Agreement contains representations and warranties which are customary for facilities of this type and covenants and provisions that, among other things, require the Company to maintain (a) a maximum net debt to EBITDA ratio of 3.00 and (b) a minimum interest coverage ratio of 3.50. The Company was in compliance with all of its covenants under the Credit Agreement at December 31, 2014.
	Under the Credit Agreement, interest rates are based on the London Interbank Offered Rate plus an applicable margin that varies from 1.25% to 2.00% depending on the Net Debt to EBITDA Ratio, as defined in the Credit Agreement.  The Company will incur commitment fees at an annual rate of 0.20% to 0.30% of the applicable margin on the committed amounts not drawn, depending on the Net Debt to EBITDA Ratio. As of December 31, 2014, the applicable interest rate on Credit Agreement borrowings was 1.48% on US Dollar borrowings and 1.55% on Euro borrowings. The balance of the facility is due upon maturity in December 2018.
	French Employee Profit Sharing
	At both December 31, 2014 and 2013, long-term debt other than the Credit Agreement primarily consisted of obligations of the French operations related to government-mandated profit sharing. Each year, representatives of the workers at each of the French businesses can make an election for the profit sharing amounts from the most recent year ended to be invested in a financial institution or with their respective employer. To the extent that funds are invested with the Company, these amounts bear interest at 2.28% and 2.43% at December 31, 2014 and 2013, respectively, and are generally payable in the fifth year subsequent to the year the profit sharing is accrued.
	Bank Overdrafts and Other
	The Company also had bank overdraft facilities of $30.8 million and $28.3 million, at December 31, 2014 and 2013, respectively, of which $0.4 million and $1.7 million were outstanding at December 31, 2014 and 2013, respectively, and reported as current debt on the consolidated balance sheet. Interest is incurred on outstanding amounts at market rates and was 0.55% and 0.74%, respectively, at December 31, 2014 and 2013. No commitment fees are paid on the unused portion of these facilities.
	Other debt consists of non-interest bearing debt with deferred capital repayment from governmental and commercial institutions primarily related to environmental capital improvements.
	Rate Swap Agreement
	The Company maintained a forward interest rate swap agreement on a portion of its long-term debt as of December 31, 2014 that will fix the LIBOR rate on $50.0 million of the Company's variable-rate long-term debt as of October 2014 at a predetermined rate plus a credit spread through the end of October 2018. The impact of swap agreements on the consolidated financial statements was not material for the years ended December 31, 2014 and 2013. See Note 13. Derivatives for more information.
	Principal Repayments
	Under the Credit Agreement, the Company selects an "interest period" for each of its borrowings. The Company can repay such borrowings and borrow again at a subsequent date if it chooses to do so, providing it flexibility and efficient use of any excess cash. The Company expects to continue to file notices of continuation related to its borrowings outstanding at December 31, 2014 such that those amounts are not expected to be repaid prior to the December 2018 expiration of the Credit Agreement. Following are the expected maturities for the Company's debt obligations as of December 31, 2014 ($ in millions):
	2015	$	2.9

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives
	In the normal course of business, the Company is exposed to foreign currency exchange rate risk and interest rate risk on its variable-rate debt. To manage these risks, the Company utilizes a variety of practices including, where considered appropriate, derivative instruments. The Company has no derivative instruments for trading or speculative purposes nor any derivatives with credit risk-related contingent features. All derivative instruments used by the Company are either exchange traded or are entered into with major financial institutions in order to reduce credit risk and risk of nonperformance by third parties. The fair values of the Company's derivative instruments are determined using observable inputs and are considered Level 2 assets or liabilities.
	The Company utilizes currency forward, swap and, to a lesser extent, option contracts to selectively hedge its exposure to foreign currency risk when it is practical and economical to do so. The use of these contracts minimizes transactional exposure to exchange rate changes. We designate certain of our foreign currency hedges as cash flow hedges. Changes in the fair value of cash flow hedges are reported as a component of other comprehensive income (loss) and reclassified into earnings when the forecasted transaction affects earnings. For foreign exchange contracts not designated as cash flow hedges, changes in the contracts' fair value are recorded to net income each period.
	The Company selectively hedges its exposure to interest rate increases on variable-rate, long-term debt when it is practical and economical to do so. Changes in the fair value of interest rate contracts considered cash flow hedges are reported as a component of other comprehensive income (loss) and reclassified into earnings when the forecasted transaction affects earnings.

	The decrease in our 2014 effective tax rate reflects the change in our geographic mix of earnings with a concentration of earnings from lower taxed jurisdictions. The lower rate was also driven primarily by global asset realignment actions taken during the early part of 2014 to improve the Company's use of critical assets along with a reorganization of foreign operations under a new holding company structure. The 2013 and 2012 foreign income tax rate differential includes the effect of not recognizing the tax benefits of a tax holiday at the RTL Philippines facility attributable to asset impairment charges. The amount of unrecognized tax benefits was $13.4 million and $2.0 million during the years ended December 31, 2013 and 2012, respectively. The RTL Philippines tax holiday expired in December 2013. The effect of not recognizing a tax benefit due to the tax holiday on net income per share (diluted) was $0.43 and $0.06 for 2013 and 2012, respectively. During 2013, the Company increased its valuation allowances by $1.2 million primarily attributed to partially reserving the net deferred tax assets in Poland due to the change in tax status for that entity in early 2014.
	The Company considers the undistributed earnings of certain foreign subsidiaries to be indefinitely reinvested. Accordingly, no provision for U.S. federal and state income taxes has been made thereon. Upon distribution of those earnings in the form of dividends, loans to the U.S. parent, or otherwise, the Company could be liable for both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to foreign tax authorities. Determination of the amount of unrecognized deferred U.S. tax liability is not practicable because of the complexities associated with this hypothetical calculation.
	Net deferred income tax assets (liabilities) were comprised of the following ($ in millions):
		December 31,
	Current deferred income tax assets attributable to:	2014			2013
	Inventories	$	0.6		$	(1.0	)

	Other	3.7			3.4
	Net noncurrent deferred income tax liabilities	$	(71.4	)	$	(80.9	)
	Net deferred tax assets in Brazil, the Philippines and Spain tax jurisdictions are fully reserved by valuation allowances. Total gross deferred income tax assets were $90.1 million and $43.1 million at December 31, 2014 and 2013, respectively. Total gross deferred income tax liabilities were $152.3 million and $113.9 million at December 31, 2014 and 2013, respectively.
	The net operating loss carryforward balances, or NOLs, were primarily generated due to operating losses incurred in Brazil and as a result of lower operating earnings together with substantial restructuring expenses incurred in Brazil and France. Also, NOLs had been generated since 2003 by the SMH tax group in France and by SM-Spain since its formation in 1997.
	As of December 31, 2014 the Company had approximately $97.5 million of operating loss carryforwards available to reduce future taxable income. Under current tax laws, remaining NOLs in France, Spain and Brazil carry forward indefinitely and NOLs in the Philippines expire 3 years subsequent to year generated. NOLs of approximately $18.4 million in the Philippines will expire from 2015 through 2017 and NOLs in the United States totaling $11.7 million related to various states will expire from 2022 through 2032 if not utilized against taxable income. The remaining $3.3 million, $20.7 million, and $43.4 million of NOLs are related to France, Brazil and Spain, respectively, and have no expiration date.
	The Company's deferred tax asset valuation allowances are primarily the result of uncertainties regarding the future realization of recorded tax benefits on tax loss carryforwards for certain entities. The valuation allowance on deferred tax assets associated with NOLs in Spain totaled $12.2 million as of December 31, 2014, fully reserving the related deferred tax asset. The valuation allowances in Brazil and the Philippines totaled $7.9 million and $16.5 million, respectively, fully reserving the net deferred tax asset balances. The Company's assumptions, judgments and estimates relative to the valuation of these net deferred tax assets take into account available positive and negative evidence of realizability, including recent financial performance, the ability to realize benefits of restructuring and other recent actions, projections of the amount and category of future taxable income and tax planning strategies. Actual future operating results and the underlying amount and category of income in future periods could differ from the Company's current assumptions, judgments and estimates. The Company believes that it will generate sufficient future taxable income to realize the tax benefits related to the remaining net deferred tax assets, including the deferred tax assets associated with the NOLs in France.
	The following table summarizes the activity related to the Company's unrecognized tax benefits related to income taxes ($ in millions):
		31-Dec-14
	Uncertain tax position balance at beginning of year	$	1.8
Increases related to current year tax positions	—
Uncertain tax position balance at end of year	$	1.8
All unrecognized tax positions would impact the Company's effective tax rate if recognized. The Company's policy with respect to penalties and interest in connection with income tax assessments or related to unrecognized tax benefits is to classify penalties as provision for income taxes and interest as interest expense in its consolidated income statement. There were no material income tax penalties or interest accrued during the years ended December 31, 2014, 2013 or 2012.
The Company files income tax returns in the U.S. Federal and several state jurisdictions as well as in many foreign jurisdictions. With certain exceptions, the Company is no longer subject to U.S. Federal, state and local, or foreign income tax examinations for years before 2011.

Compensation and Retirement Disclosure [Abstract]
Postretirement and Other Benefits	Postretirement and Other Benefits
	North American Pension and Postretirement Healthcare and Life Insurance Benefits
	The U.S. operations have defined benefit retirement plans that cover certain full-time employees. Retirement benefits are based on either a cash balance benefit formula or a final average pay formula for certain employees who were "grandfathered" and retained retirement benefits under the terms of the plan prior to its amendment to include a cash balance benefit formula. Benefits related to the U.S. defined benefit and pension plan are frozen for all employees.
	The U.S. operations also have unfunded healthcare and life insurance benefit plans, or OPEB plans, which cover certain of its retirees through age 65. Some employees who retained benefits under the terms of the Company's plans prior to certain past amendments receive retiree healthcare coverage at rates subsidized by the Company. For other eligible employees, retiree healthcare coverage access is offered at full cost to the retiree. The postretirement healthcare plans include a limit on the Company's share of costs for current and future retirees. The U.S. operations' retiree life insurance plans are noncontributory. The Company's Canadian postretirement benefits liability is immaterial and therefore is not included in these disclosures.
	French Pension Benefits
	In France, employees are covered under a government-administered program. In addition, the Company's French operations sponsor retirement indemnity plans, which pay a lump sum retirement benefit to all of its permanent employees who retire. In addition, the Company's French operations sponsor a supplemental executive pension plan. Plan assets are principally invested in the general asset portfolio of a French insurance company.
	U.S. and French Pension and U.S. Other Postretirement Benefit Disclosures
	The U.S. pension and OPEB plans and French pension plans accounted for the majority of the Company's total plan assets and total ABO at December 31, 2014 for the Company and all of its consolidated subsidiaries.

	Actuarial assumptions are used to determine the Company's benefit obligations. The discount rate represents the interest rate used to determine the present value of future cash flows currently expected to be required to settle pension obligations. The discount rate fluctuates from year to year based on current market interest rates for high-quality, fixed-income investments. The Company also evaluates the expected average duration of its pension obligations in determining its discount rate. An assumed long-term rate of compensation increase is also used to determine the PBO. The weighted average assumptions used to determine benefit obligations as of December 31, 2014 and 2013 were as follows:
		Pension Benefits											OPEB Benefits
		United States						France					United States
		2014			2013			2014			2013		2014			2013

	Rate of compensation increase	—	%		—	%		1.9	%		2.5	%	3.5	%		3.5	%
	The U.S. postretirement healthcare plan provides for benefits to be limited to a cost ceiling which has already been reached. Therefore, no increases in the health care cost trend rates are included in the measurement of the plan's benefit obligation.
	The components of net pension and OPEB benefit costs for U.S. employees and net pension benefit costs for French employees during the years ended December 31, 2014, 2013 and 2012 were as follows ($ in millions):

The Company's investment strategy with respect to its U.S. pension plan assets is to maximize the return on investment of plan assets at an acceptable level of risk and to assure the plans' fiscal health. The target asset allocation varies based on the funded status of the plan in an effort to match the duration of the plan's liabilities to investments in long duration fixed income assets over time. The Company's investments under the French pension plans are primarily invested as directed by governmental authorities, their contracted providers or the participants without direction from the Company. The primary goal of the Company's pension plans is to maintain the highest probability of assuring future benefit payments to participants while providing growth of capital in real terms. To achieve this goal, the investment philosophy is to protect plan assets from large investment losses, particularly over time, while steadily growing the assets in a prudent manner. While there cannot be complete assurance that the objectives will be realized, the Company believes that the likelihood of realizing the objectives are reasonable based upon this investment philosophy. The Company has an investment committee that meets on a periodic basis to review the portfolio returns and to determine asset mix targets. The U.S. and French pension plans' asset target allocations by asset category for 2015 and actual allocations by asset category at December 31, 2014 and 2013 were as follows:
	United States									France
	2015 Target			2014			2013			2014		2013

*	None of the Company's pension plan assets are targeted for investment in SWM stock, except that it is possible that one or more mutual funds held by the plan could hold shares of SWM.
**	Investments in this category under the U.S. pension plan only may include hedge funds, and may include real estate under the French pension plan.
The Company's pension assets are classified according to an established fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are described below:
Level 1	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2	Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly;
Level 3	Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

The Company is not required to contribute during 2015 to its U.S. and French pension plans; although, it may make discretionary contributions dependent on market conditions to remain aligned with its investment policy statement.
Other Foreign Pension Benefits
In Brazil and Poland, employees are covered under government-administered programs. In Poland and Canada, the employee pension benefits are not significant and therefore are not included in the above disclosures.
Other Benefits
We sponsor a qualified defined contribution plan covering substantially all U.S. employees. Under the plan, the Company matches a portion of employee contributions. The Company's cost under the plan was $2.0 million, $1.8 million and $1.7 million for the years ended December 31, 2014, 2013 and 2012, respectively.
The Company provides U.S. executives, certain other key personnel and its directors the opportunity to participate in deferred compensation plans. Participating employees can elect to defer a portion of their salaries and certain other compensation. Participating directors can elect to defer their meeting fees, as a cash deferral, as well as their quarterly retainer fees, as deferred stock unit credits. The Company's liability balance under these deferred compensation plans totaled $13.1 million and $13.4 million at December 31, 2014 and 2013, respectively, which were included in the consolidated balance sheet in other liabilities. In connection with these plans, the Company has a grantor trust into which it has contributed funds toward its future obligations under the various plans (See Note 10, Other Assets). The balance of grantor trust assets totaled $10.3 million and $10.0 million at December 31, 2014 and 2013, respectively, which were included in other assets in the consolidated balance sheets. These assets are restricted from Company use until all obligations are satisfied.
In accordance with French law, certain salaried employees in France may accumulate unused regular vacation and supplemental hours of paid leave that can be credited to an individual's Compte Epargne Temps, or CET. The CET account may grow over an individual's career and the hours accumulated may be withdrawn upon retirement or under other special circumstances at the individual's then current rate of pay. The balance of the Company's liability for this program reflected in the accompanying consolidated balance sheets in other liabilities was $8.1 million and $8.9 million at December 31, 2014 and 2013, respectively.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders' Equity
	Restricted Stock Plan
	The Company's Restricted Stock Plan, or RSP, is intended to promote the Company's long-term financial success by attracting and retaining outstanding executive personnel and to motivate such personnel by means of restricted stock grants. The Compensation Committee of the Company's Board of Directors selects participants and establishes the terms of any grant of restricted stock. The Company's RSP provides that issuance of restricted stock immediately transfers ownership rights in shares of its Common Stock to the recipient of the grant, including the right to vote the shares and to receive dividends thereon. The recipient's continued ownership of and right to freely transfer the restricted stock is subject to such conditions on transferability and to such risks of forfeiture as are established by the Compensation Committee at the time of the grant, which may include continued employment with the Company for a defined period, achievement of specified management performance objectives or other conditions established by the Compensation Committee. The number of shares, which may be issued under this RSP, is limited to 2,000,000 shares. No single participant may be awarded, in the aggregate, more than 50% of the shares authorized to be issued under the RSP.
	As of December 31, 2014, 1,226,112 restricted shares had been issued under the RSP of which 366,363 shares of issued restricted stock were not yet vested and for which $2.8 million in unrecognized compensation expense is expected to be recognized over a weighted average period of 2.0 years. The following table presents restricted stock activity for the years 2014, 2013 and 2012:
		2014							2013					2012

	Restricted Stock Plan Performance Based Shares
	During 2014, the Company recognized $1.1 million for 43,842 shares earned under the 2014-2015 award opportunity and $3.1 million of compensation expense earned under the 2013-2014 award opportunity. During 2013 and 2012, the Company recognized $2.9 million and $6.2 million, respectively, of compensation expense for 159,940 and 177,034 shares, respectively, earned under the 2013-2014 and 2012-2013 award opportunities under the Restricted Stock Plan, with an offsetting credit to additional paid-in capital.
	Basic and Diluted Shares Reconciliation
	The Company uses the two-class method to calculate earnings per share. The Company has granted restricted stock that contains nonforfeitable rights to dividends on unvested shares. Since these unvested shares are considered participating securities under the two-class method, the Company allocates earnings per share to common stock and participating securities according to dividends declared and participation rights in undistributed earnings.
	Diluted net income per common share is computed based on net income divided by the weighted average number of common and potential common shares outstanding. Potential common shares during the respective periods are those related to dilutive stock-based compensation, including long-term share-based incentive compensation, stock options outstanding, and directors' accumulated deferred stock compensation which may be received by the directors in the form of stock or cash. A reconciliation of the average number of common and potential common shares outstanding used in the calculations of basic and diluted net income per share follows ($ in millions, shares in thousands):
		For the Years Ended December 31,

	Average number of common and potential common shares outstanding	30,356.50				31,238.30				31,341.90
	There were no anti-dilutive stock options during the years ended December 31, 2014, 2013 or 2012.

	Other Commitments
	The Paper segment has minimum purchase agreements during 2015 for flax fiber of approximately $3 million. The Paper segment's PdM mill has a minimum annual commitment of approximately $2 million per year for calcium carbonate purchases, a raw material used in the manufacturing of some paper products, which totals approximately $18 million through 2024. Future purchases are expected to be at levels that exceed such minimum levels under these contracts.
	The Company enters into certain other immaterial contracts from time to time for the purchase of certain raw materials. The Company also enters into certain contracts for the purchase of equipment and related costs in connection with its ongoing capital projects.
	The Company has agreements with an energy cogeneration supplier in France whereby the supplier constructed and operates a cogeneration facility at certain mills and supplies steam that is used in the operation of these mills. The Company is committed to purchasing minimum annual amounts of steam generated by these facilities under the agreements through 2024. These minimum annual commitments total approximately $4 million. The Company's current and expected requirements for steam at these facilities are at levels that exceed the minimum levels under the contracts.
	The Paper segment's Brazilian mill, SWM-B, has an agreement for the transmission and distribution of energy that covers all of the mill's consumption of electrical energy valued at approximately $4 million annually through 2015. The French mills have contracts for natural gas to be distributed to and consumed at PdM, LTRI and St. Girons. The value of the natural gas and distribution to be provided under these contracts is estimated at approximately $16 million in 2015.
	The Company has certain other letters of credit, guarantees and surety bonds outstanding at December 31, 2014, which are not material either individually or in the aggregate.
	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. in December of 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 Assessment.
	The Raw Materials Assessment 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. 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 and is covered in part by an indemnification from the sellers of the Pirahy mill. The second assessment, or Assessment 2 (case number 2001.001.064544-6), pertains exclusively to periods that SWM-B owned the Pirahy mill. While SWM-B would be primarily responsible for the full payment of the Assessment in the event of an ultimate unfavorable outcome, SWM-B is not aware of any difficulties that would be encountered in obtaining reimbursement of that portion of any payment resulting from Assessment 1 from the previous owners of the Pirahy mill under the indemnification.
	SWM-B has contested the Raw Materials Assessment based on Article 150, VI of the Brazilian Federal Constitution of 1988, which grants immunity from ICMS taxes to papers used in the production of books, newspapers and periodicals, or immune papers, and the raw material inputs used to produce immune papers.
	Both Raw Materials Assessments are presently on appeal in separate chambers of the Federal Supreme Court of Brazil. SWM-B won a favorable ruling in both assessments at the first level, then lost Assessment 1 on appeal and won Assessment 2 on appeal. Assessment 1 is before the court on SWM-B's appeal of a procedural question which, if decided favorably, would invalidate Assessment 1. If decided against SWM-B, the lower court would be notified to send the case records to the Federal Supreme Court for a decision on the merits.  Assessment 2 is before the Federal Supreme Court of Brazil on the State's appeal on the merits and will be finally decided by the action of the chamber of the court hearing the matter, unless there is a prior decision by a chamber of the Federal Supreme Court on Assessment 1 that is in contradiction, in which case the conflict between the rulings of the different chambers would be decided by the Federal Supreme Court sitting as a whole.  No docket entry has been made yet regarding argument on either assessment.   Based on the foreign currency exchange rate at December 31, 2014, the Raw Materials Assessment totaled approximately $38 million, of which approximately $17 million is covered by the above-discussed indemnification.
	More recently, SWM-B has received assessments from the tax authorities of the State of Rio de Janeiro for unpaid ICMS and Fundo Estadual de Combate à Pobreza (FECP) taxes on interstate purchases of electricity. The state issued three assessments against SWM-B, one for May 2006 - November 2007, a second for January 2008 - December 2010, and in October 2013, a third assessment for September 2011 - September 2013, collectively the Electricity Assessment. SWM-B has challenged all three Electricity Assessments in administrative proceedings before the state tax council (Junta de Revisão Fiscal) based on Resolution 1.610/89, which defers these taxes on electricity purchased by an "electricity-intensive consumer."
	SWM-B's challenges to the first two Electricity Assessments were unsuccessful at the first administrative level, but different appeals chambers of the Conselho de Contribuintes have reached different conclusions about the assessments. On the first electricity assessment, one chamber of the Conselho de Contribuintes recognized that SWM-B is an electricity-intensive consumer but denied applicability of the tax deferral resolution. On the second electricity assessment, a different chamber of the Conselho de Contribuintes recognized that SWM-B is an electricity-intensive consumer and agreed that the tax deferral resolution applies. In October and November 2014, the full administrative council of the Conselho de Contribuintes announced a decision against SWM-B in both the first and second electricity assessments. The first and second electricity assessment totaled approximately $14.0 million as of December 31, 2014. SWM-B intends to challenge the ruling in court proceedings if the full administrative council's decision becomes final. SWM-B's challenge to the third electricity assessment is pending at the first administrative level (Junta de Revisão Fiscal). Based on the foreign currency exchange rate at December 31, 2014, the electricity assessments totaled approximately $18.0 million.
	SWM-B believes that both the Raw Materials Assessments 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.
	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 or results of operations. However, future events, such as changes in existing laws and regulations, 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) may give rise to additional costs which could have a material effect on its financial condition or results of operations.
	The Company incurs spending necessary to meet legal requirements and otherwise relating to the protection of the environment at its facilities in the United States, France, Poland, Brazil, China and Canada. For these purposes, the Company incurred total capital expenditures of $1.4 million in 2014, and expects to incur less than $2.0 million in each of 2015 and 2016, of which no material amount is the result of environmental fines or settlements. The foregoing capital expenditures are not expected to reduce the Company's ability to invest in other appropriate and necessary capital projects and are not expected to have a material adverse effect on its financial condition or results of operations.
	Indemnification Matters
	In connection with its spin-off from Kimberly-Clark in 1995, the Company undertook to indemnify and hold Kimberly-Clark harmless from claims and liabilities related to the businesses transferred to it that were not identified as excluded liabilities in the related agreements. As of December 31, 2014, there are no claims pending under this indemnification that the Company deems to be material.
	General Matters
	In the ordinary course of conducting business activities, the Company and its subsidiaries become involved in certain other judicial, administrative and regulatory proceedings involving both private parties and governmental authorities. These proceedings include insured and uninsured regulatory, employment, intellectual property, general and commercial liability, environmental and other matters. At this time, the Company does not expect any of these proceedings to have a material effect on its reputation, business, financial condition, results of operations or cash flows. However, 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 three operating product line segments are also the Company's reportable segments: Paper, Reconstituted Tobacco and Filtration. The Paper segment primarily produces Cigarette Papers such as cigarette papers, including LIP papers, plug wrap papers and base tipping papers used to wrap various parts of a cigarette for sale to cigarette manufacturers. The Paper segment also includes commercial and industrial products such as lightweight printing and writing papers, battery separator paper, drinking straw wrap, filter paper and other specialized papers. These non-tobacco industry products are generally sold directly to converters and other end-users or brokers. The Reconstituted Tobacco segment produces reconstituted tobacco leaf, or RTL, and wrapper and binder products for sale to cigarette and cigar manufacturers. The Filtration segment primarily produces nonwoven materials which are critical components performing support, separation or filtration functions.
	Information about Net Sales and Operating Profit
	The accounting policies of these segments are the same as those described in Note 2. Summary of Significant Accounting Policies. The Company primarily evaluates segment performance and allocates resources based on operating profit. Expense amounts not associated with segments are referred to as unallocated expenses. Certain of the Company's assets are used in the production of both the Paper and Reconstituted Tobacco segments' products. Due to these shared assets, management does not evaluate assets by segment.

	Philip Morris-USA, Philip Morris International, or PMI, British American Tobacco, or BAT, and Japan Tobacco Inc. together with their respective affiliates and designated converters, each accounted for 10% or more of the Company's consolidated net sales for each of the periods presented and together accounted for 46%, 57% and 55% of the Company's 2014, 2013 and 2012 consolidated net sales, respectively. The loss of one or more such customers, or a significant reduction in one or more of these customers' purchases, could have a material adverse effect on the Company's results of operations.
	Philip Morris-USA, PMI, BAT and Japan Tobacco Inc., together with their respective affiliates and designated converters accounted for 29% and 25% of consolidated accounts receivable at December 31, 2014 and 2013, respectively.
	The Company performs ongoing credit evaluations on all of its customers' financial condition and generally does not require collateral or other security to support customer receivables. Substantial portions of the Company's consolidated accounts receivable are due from companies in the tobacco industry, which has been and continues to be under substantial pressure from legal, regulatory and tax developments. It is not possible to predict the outcome of such litigation or what effect adverse developments in pending or future litigation, regulatory actions and additional taxes may have on the tobacco industry, its financial liquidity or relationships with its suppliers. Nor is it possible to predict what additional legislation or regulations relating to tobacco products will be enacted, or to what extent, if any, such legislation or regulations might affect the tobacco products industry in general.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying consolidated financial statements and the notes thereto have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. The Company believes the estimates and assumptions used in the preparation of these consolidated financial statements are reasonable, based upon currently available facts and known circumstances. Actual results may differ from those estimates and assumptions as a result of a number of factors, including those discussed elsewhere in this report and in its other public filings from time to time.
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and wholly-owned, majority-owned and controlled subsidiaries. Intercompany balances and transactions have been eliminated.
	The Company has two joint ventures with China National Tobacco Corporation, or CNTC. CNTC is the principal operating Company under China's State Tobacco Monopoly Administration. CNTC and our subsidiary, SM-China, each own 50% of the joint ventures. The paper joint venture China Tobacco Mauduit (Jiangmen) Paper Industry Co. LTD, or CTM, produces tobacco-related papers in China. The second joint venture China Tobacco Schweitzer (Yunnan) Reconstituted Tobacco Co. LTD., or CTS, produces reconstituted tobacco leaf products. The Company uses the equity method to account for both joint ventures. Investment in equity affiliates represents the Company's investment in its China joint ventures. The Company's share of the net income of its 50% owned joint ventures in China are included in the consolidated statements of income as income from equity affiliates.
Revenue Recognition	Revenue Recognition
	The Company recognizes revenue and the related accounts receivable when the following four criteria are met: (1) persuasive evidence of an arrangement exists; (2) ownership has transferred to the customer; (3) the selling price is fixed or determinable; and (4) collection is reasonably assured based on the Company's judgment regarding the collectability of its accounts receivable. Generally, the Company recognizes revenue when it ships its manufactured product and title and risk of loss passes to its customer in accordance with the terms of sale of the product. Revenue is recorded at the time of shipment for terms designated f.o.b., or free on board, shipping point. For sales transactions designated f.o.b. destination, revenue is recorded when the product is delivered to the customer's delivery site, at which time title and risk of loss are transferred. Provisions for discounts, returns, allowances, customer rebates and other adjustments are provided for in the same period the related revenue is recorded. Deferred revenue represents advance payments from customers which are earned based upon a mutually agreed-upon amount per unit of future product sales.
	Freight Costs
	The cost of delivering finished goods to the Company's customers is recorded as a component of cost of products sold. Those costs include the amounts paid to a third party to deliver the finished goods. Any freight costs billed to and paid by a customer are included in revenue.
	Royalty Income
	Royalties from non-exclusive, third-party patent licenses are recognized when earned, including monies received at an agreement's initiation attributable to past sales. The Company recognizes up-front payments upon receipt when it has no future performance requirement or ongoing obligation arising from its agreements and the payment is for a separate earnings process. Minimum annual royalties received in advance are deferred and are recognized in the period earned.
Foreign Currency Translation	Foreign Currency Translation
	The income statements of foreign entities are translated into U.S. dollars at average exchange rates prevailing during the periods presented. The balance sheets of these entities are translated at period-end exchange rates, and the differences from historical exchange rates are reflected in a separate component of accumulated other comprehensive income (loss) as unrealized foreign currency translation adjustments.
	Foreign currency risks arise from transactions and balances denominated in non-local currencies.
Derivative Instruments	Derivative Instruments
	The Company is exposed to changes in foreign currency exchange rates, interest rates and commodity prices. The Company utilizes a variety of practices to manage these market risks, including where considered appropriate, derivative instruments. The Company uses derivative instruments only for risk management purposes and not for trading or speculation. All derivative instruments the Company uses are either exchange traded or are entered into with major financial institutions in order to reduce credit risk and risk of nonperformance by third parties. The Company believes the credit risks with respect to the counterparties, and the foreign currency risks that would not be hedged if the counterparties fail to fulfill their obligations under the contracts, are not material in view of its understanding of the financial strength of the counterparties.
	Gains and losses on instruments that hedge firm commitments are deferred and included in the basis of the underlying hedged items. All other hedging gains and losses are included in period income or expense based on the period-end market price of the instrument and are included in the Company's operating cash flows.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company considers all highly liquid, unrestricted investments with remaining maturities of three months or less to be cash equivalents, including money market funds with no restrictions on withdrawals.
Business Combinations	Business Combinations
	The Company uses the acquisition method of accounting for business combinations. At the acquisition date, the Company records assets acquired and liabilities assumed at their respective fair market values. The Company estimates fair value using the exit price approach which is the price that would be received to sell an asset or paid to transfer a liability in an orderly market. An exit price is determined from a market participant's viewpoint in the principal or most advantageous market and may result in the Company valuing assets or liabilities at a fair value that is not reflective of the Company's intended use of the assets or liabilities. Any excess consideration above the estimated fair values of the net assets acquired is recognized as goodwill on the Company's Consolidated Balance Sheets. The operating results of acquired businesses are included in the Company's results of operations beginning as of their effective acquisition dates.
Impairment of Long-Lived Assets, Goodwill and Intangible Assets	Impairment of Long-Lived Assets, Goodwill and Intangible Assets
	The Company evaluates the carrying value of long-lived assets, including property and equipment, goodwill and intangible assets when events and circumstances warrant a review. Goodwill is also tested for impairment annually during the fourth quarter. Goodwill may be evaluated using a qualitative evaluation and/or a two-step test at the reporting unit level. The first step compares the book value of the reporting unit to its fair value. If the book value of a reporting unit exceeds its fair value, we perform the second step. In the second step, we determine an implied fair value of the reporting unit's goodwill by allocating the fair value of the reporting unit to all of the assets and liabilities other than goodwill. The difference between the total fair value of the reporting unit and the fair value of all the assets and liabilities other than goodwill is the implied fair value of that goodwill. Any impairment loss is measured as the excess of the book value of the goodwill over the implied fair value of that goodwill. See Note 8. Goodwill for further discussion of the Company's annual impairment test results.
	We have acquired trade names that have been determined to have indefinite lives. We evaluate a number of factors to determine whether an indefinite life is appropriate, including the competitive environment, category share, business history, product life cycle and operating plans. Indefinite-lived intangibles are evaluated for impairment annually during the fourth quarter. Additionally, when certain events or changes in operating conditions occur, an impairment assessment is performed and indefinite-lived trade names may be adjusted to a determinable life or an impairment charge may be recorded.
	The cost of intangible assets with determinable useful lives is amortized to reflect the pattern of economic benefits consumed, which approximates a straight-line basis, over the estimated periods benefited. When certain events or changes in operating conditions occur, an impairment assessment is performed and lives of intangible assets with determinable lives may be adjusted.
	The carrying value of long-lived assets is reviewed to determine if events or circumstances have changed which may indicate that the assets may be impaired or the useful life may need to be changed. Upon occurrence of such a triggering event, the Company considers internal and external factors relating to each asset group, including expectation of future profitability, undiscounted cash flows and its plans with respect to the operations. If impairment is indicated, an impairment loss is measured by the amount the net carrying value of the asset exceeds its estimated fair value.
Environmental Spending	Environmental Spending
	Environmental spending is capitalized if such spending qualifies as property, plant and equipment, substantially increases the economic value or extends the useful life of an asset. All other such spending is expensed as incurred, including fines and penalties incurred in connection with environmental violations. Environmental spending relating to an existing condition caused by past operations is expensed. Liabilities are accrued when environmental assessments are probable and the costs can be reasonably estimated. Generally, timing of these accruals coincides with completion of a feasibility study or commitment to a formal plan of action.
Capitalized Software Costs	Capitalized Software Costs
	The Company capitalizes certain purchases of software and software development costs in connection with major projects of software development for internal use. These costs are included in other assets on the consolidated balance sheets and are amortized using the straight-line method over the estimated useful life not to exceed seven years. Costs associated with business process redesign, end-user training, system start-up and ongoing software maintenance are expensed as incurred.
Business Tax Credits	Business Tax Credits
	Business tax credits represent value added tax credits receivable and similar assets, such as Imposto sobre Circulação de Mercadorias e Serviços, or ICMS, in Brazil. Business tax credits are generated when value-added taxes, or VAT, are paid on purchases. VAT and similar taxes are collected from customers on certain sales. In some jurisdictions, export sales do not require VAT collection.
Income Taxes	Income Taxes
	The Company uses an asset and liability approach to account for and report income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense (benefit) is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. Valuation allowances are recognized to reduce deferred tax assets to the amount that is more likely than not to be realized. In assessing the likelihood of realization, the Company considers sources of future taxable income.
	In connection with income tax assessments or unrecognized tax benefits, the Company classifies penalties as provision for income taxes and interest as interest expense in its consolidated statements of income.
	The Company files income tax returns in the U.S. Federal and several state jurisdictions as well as in many foreign jurisdictions. In France, the Company reorganized its legal entities to maximize utilization of its net operating loss carryforwards. With certain exceptions, the Company is no longer subject to U.S. Federal, state and local, or foreign income tax examinations for years before 2011.
Pensions and Other Postretirement Benefit Accounting	Pension and Other Postretirement Benefits Accounting
	The Company recognizes the estimated compensation cost of employees' pension and other postretirement benefits over their approximate period of service. The Company's earnings are impacted by amounts of expense recorded related to these benefits, which primarily consist of U.S. and French pension benefits and U.S. other postretirement benefits, or OPEBs. Each year's recorded expenses are estimates based on actuarial calculations of the Company's accumulated and projected benefit obligations, or PBOs, for the Company's various plans.
	Suspension of additional benefits for future service is considered a curtailment, and if material, necessitates a re-measurement of plan assets and PBO. As part of a re-measurement, the Company adjusts its discount rates and other actuarial assumptions, such as retirement, turnover and mortality table assumptions, as appropriate.
Comprehensive Income	Comprehensive Income
	Comprehensive income includes net income, as well as items charged and credited directly to stockholders' equity, which are excluded from net income. The Company has presented comprehensive income in the consolidated statements of comprehensive income (loss). Reclassification adjustments of derivative instruments are presented in Net Sales in the consolidated statements of income. See Note 13. Derivatives for additional information. Amortization of accumulated pension and other post-employment benefit (OPEB) liabilities are included in the computation of net periodic pension and OPEB costs, which are more fully discussed in Note 16. Postretirement and Other Benefits.
Restricted Stock	Restricted Stock
	All of the Company's restricted stock grants, including those that have been earned in the case of performance-based shares and cliff-vesting grants that are not performance based, vest upon completion of a specified period of time. The fair value of each award is equal to the share price of the Company's stock on the date of the grant. This cost is recognized over the vesting period of the respective award.
Restricted Stock Plan Performance Based Shares	Restricted Stock Plan Performance Based Shares
	The Company's long-term incentive compensation program, or LTIP, for key employees includes an equity-based award component that is provided through its Restricted Stock Plan, or RSP. The objectives under the LTIP are established for the immediate following year at the beginning of a performance cycle and are intended to focus management on longer-term strategic goals. The Compensation Committee of the Board of Directors designates participants in the LTIP and RSP and determines the equity-based award opportunity in the form of restricted stock for each performance cycle, which is generally measured on the basis of a one or two-year performance period. Performance is measured on a cumulative basis and each performance cycle's restricted stock award opportunity is earned annually. The restricted shares are considered issued and outstanding when the number of shares becomes fixed, after the annual performance is determined, and such awards vest at the end of the performance cycle or some predetermined period thereafter. The Company recognizes compensation expense with an offsetting credit to additional paid-in-capital over the performance period based on the fair value of the award at the date of grant, with compensation expense being adjusted cumulatively based on the number of shares expected to be earned according to the level of achievement of performance goals.
Fair Value Option	Fair Value Option
	The Company has elected not to measure its financial instruments or certain commitments at fair value.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-08 (ASU 2014-08) "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. The Company adopted this guidance as of January 1, 2015. Adoption of ASU 2014-08 did not have an impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" (Topic 606). The new guidance specifies how and when an entity will recognize revenue arising from contracts with customers and requires entities to disclose information about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The guidance is effective for annual periods beginning on or after December 15, 2016 and may be implemented using a full retrospective or a modified retrospective application. The Company is currently in the process of evaluating the impact the adoption will have on our consolidated financial statements.
	In June 2014, the FASB issued Accounting Standard Update ("ASU") No 2014-12, "Compensation - Stock Compensation: Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. Compensation cost should be recognized in the period in which it becomes probably that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The amendment is effective for annual reporting periods including interim reporting within those periods beginning after December 15, 2015. Earlier adoption is permitted. The Company is currently in the process of evaluating the impact the adoption will have on our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements-Going Concern" (Subtopic 205-40). The Update provides U.S. GAAP guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. This update is effective for annual periods ending after December 15, 2016 and interim periods thereafter. Early adoption is permitted. The Company adopted this guidance as of December 31, 2014. Adoption of ASU 2014-15 did not have an impact on our consolidated financial statements.
	In November 2014, the FASB released Accounting Standards Update (ASU) 2014-17, "Business Combinations (Topic 805): Pushdown Accounting, a consensus of the FASB Emerging Issues Task Force. This ASU amends FASB Accounting Standards Codification (FASB ASC) 805, Business Combinations", to provide guidance on whether and at what threshold an acquired entity that is a business or not-for-profit (NFP) entity can apply pushdown accounting in its separate financial statements. The amendments in this ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The amendments in this ASU are effective on November 18, 2014, or upon issuance. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. The Company adopted this guidance as of December 31, 2014. Adoption of ASU 2014-17 did not have a material impact on our consolidated financial statements.
	In November 2014, the FASB issued ASU 2014-16, "Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity." The update requires an entity to determine the nature of the host contract by considering all stated and implied substantive terms and features of the hybrid financial instrument, weighing each term and feature on the basis of the relevant facts and circumstances (commonly referred to as the whole-instrument approach). This guidance is effective for annual periods beginning after December 15, 2015, and interim periods thereafter. Early adoption is permitted.
