	2	ACCOUNTING POLICIES
	Basis of Presentation The unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Glatfelter and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
	We prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”). In our opinion, the financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. When preparing these financial statements, we have assumed that you have read the audited consolidated financial statements included in our 2012 Annual Report on Form 10-K (“2012 Form 10-K”).
	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes that actual results may differ from those estimates and assumptions.
	Recently Issued Accounting Pronouncements In February 2013, the FASB issued ASU 2013-02 –“Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which requires new disclosures about items reclassified out of accumulated other comprehensive income. We adopted the requirements of this standard in the first quarter of 2013.

Acquisition	'
	3	ACQUISITION
	On April 30, 2013, we completed the acquisition of all outstanding shares of Dresden Papier GmbH (“Dresden”) from Fortress Paper Ltd. for approximately $211 million, net of cash acquired. Dresden, based in Heidenau, Germany, is the leading global supplier of nonwoven wallpaper base materials, and is a major supplier to most of the world’s largest wallpaper manufacturers. In 2012, Dresden’s revenues were approximately $150 million and it employed approximately 146 people at its state-of-the-art, 60,000 metric-ton-capacity manufacturing facility. We financed the acquisition through a combination of cash on hand and borrowings under our Revolving Credit Facility.
	The acquisition of Dresden will add another industry-leading nonwovens product line to our Composite Fibers business, and broaden our relationship with leading producers of consumer and industrial products. This acquisition will also provide additional operational leverage and growth opportunities for Glatfelter globally, particularly in large markets such as Russia and China, and other developing markets in eastern Europe and Asia.
	Dresden now operates as part of our Composite Fibers business unit, which manufactures fiber-based products for growing global niche markets, including filtration papers for tea and single serve coffee applications, metallized papers, composite laminates, and technical specialties.
	The share purchase agreement provides for, among other terms, indemnification provisions for claims that may arise, including among others, uncertain tax positions and other third party claims. The preliminary allocation of the purchase price to assets acquired and liabilities assumed is as follows:
	In thousands		As			Cumulative			Adjusted
			originally			Adjustments
			presented
	Assets
	Cash		$	12,227			—		$	12,227
	Accounts receivable			23,870			—			23,870
	Inventory			13,864			—			13,864
	Prepaid and other current assets			6,674			1,386			8,060
	Plant, equipment and timberlands			60,951			—			60,951
	Intangible assets			87,596			—			87,596
	Goodwill			76,256			(1,386	)		74,870
	Total assets			281,438			—			281,438
	Liabilities
	Accounts payable and accrued expenses			20,360			(107	)		20,253
	Deferred tax liabilities			36,120			—			36,120
	Other long term liabilities			1,820			107			1,927
	Total liabilities			58,300			—			58,300
	Total			223,138			—			223,138
	less cash acquired			(12,227	)		—			(12,227	)
	Total purchase price		$	210,911			—		$	210,911
	The adjustments set forth above did not impact previously reported results of operations, earnings per share, or cash flows.
	We are in the process of finalizing valuations necessary to account for this transaction in accordance with the acquisition method of accounting set forth in FASB ASC 805, Business Combinations. Accordingly, the purchase price allocation set forth above is based on all information available to us at the present time and is subject to change, and such changes could be material.
	For purposes of allocating the total purchase price, assets acquired and liabilities assumed are recorded at their estimated fair market value. The allocation set forth above is based on management’s estimate of the fair value using valuation techniques such as discounted cash flow models, appraisals and similar methodologies. The amount allocated to intangible assets represents the estimated value of customer relationships, technological know-how and trade name.
	Acquired property, plant and equipment are preliminarily being depreciated on a straight-line basis with estimated remaining lives ranging from 5 years to 30 years. Intangible assets are being amortized on a straight-line basis over an average estimated remaining life of 17 years reflecting the expected future value. In addition, approximately $9.8 million of identifiable intangible assets have an indefinite life and are not being amortized.
	The goodwill arising from the acquisition largely relates to strategic benefits, product and market diversification, assembled workforce, and similar factors. For tax purposes, all of the goodwill is non-deductible.
	Our results of operations include the results of Dresden prospectively since the acquisition was completed on April 30, 2013. All such results reported herein are included as part of the Composite Fibers business unit. Revenue and operating income of Dresden included in our consolidated results of operations for the first nine months of 2013 totaled $67.8 million and $12.3 million, respectively.
	The table below summarizes pro forma financial information as if the acquisition and related financing transaction occurred as of January 1, 2012:
			Three months ended

	Net income			63,709			67,244
	Diluted earnings per share			1.44			1.54
	During the nine months of 2013, we incurred legal, professional and advisory costs directly related to the Dresden acquisition totaling $3.2 million. For purposes of presenting the above pro forma financial information, such costs have been eliminated. All such costs are presented under the caption “Selling, general and administrative expenses” in the accompanying condensed consolidated statements of income. In addition, the pro forma financial information excludes $1.1 million of charges to costs of products sold related to the write up of inventory to fair value and $2.0 million of integration related costs. This unaudited pro forma financial information above is not necessarily indicative of what the operating results would have been had the acquisition been completed at the beginning of the respective period nor is it indicative of future results.

Income Taxes	'
	7	INCOME TAXES
	Income taxes are recognized for the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. The effects of income taxes are measured based on enacted tax laws and rates.
	As of September 30, 2013 and December 31, 2012, we had $16.7 million and $30.4 million of gross unrecognized tax benefits. As of September 30, 2013, if such benefits were to be recognized, approximately $16.7 million would be recorded as a component of income tax expense, thereby affecting our effective tax rate. The change was primarily due to the release of $9.9 million of uncertain tax positions related to alternative fuel mixture credits. The release was recorded in the third quarter in connection with the lapse of the statute of limitations.
	We, or one of our subsidiaries, file income tax returns with the United States Internal Revenue Service, as well as various state and foreign authorities.
	The following table summarizes, by major jurisdiction, tax years that remain subject to examination:
			Open Tax Years
	Jurisdiction		Examinations not		Examination

	Federal			2010 - 2012		N/A

	United Kingdom			2009 - 2012		N/A
	Philippines			2012		2010-2011
	-1	– includes provincial or similar local jurisdictions, as applicable
	The amount of income taxes we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Management performs a comprehensive review of its global tax positions on a quarterly basis and accrues amounts for uncertain tax positions. Based on these reviews and the result of discussions and resolutions of matters with certain tax authorities and the closure of tax years subject to tax audit, reserves are adjusted as necessary. However, future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are determined or resolved or as such statutes are closed. Due to potential for resolution of federal, state and foreign examinations, and the lapse of various statutes of limitation, it is reasonably possible our gross unrecognized tax benefits balance may decrease within the next twelve months by a range of zero to $5.9 million. Substantially all of this range relates to tax positions taken in the U.S., the U.K. and Germany.
	We recognize interest and penalties related to uncertain tax positions as income tax expense. For the third quarter and first nine months of 2013, we recognized a net reduction of $0.4 million and $0.1 million, respectively, of interest expense. For the third quarter and first nine months of 2012, we recognized a net reduction of $0.3 million and $0.7 million, respectively, of interest expense. As of September 30, 2013 and December 31, 2012, we had recognized a liability for interest of $1.1 million and $1.4 million, respectively. We did not record any penalties associated with uncertain tax positions during the first nine months of 2013 or 2012.
	In the third quarter of 2012, we amended our 2009 federal income tax return to claim a credit for a portion of the converted credits. This required us to return to the Internal Revenue Service $16.8 million, net of credits used to reduce estimated tax payments.

	The P. H. Glatfelter Amended and Restated Long Term Incentive Plan (the “LTIP”) provides for the issuance of Glatfelter common stock to eligible participants in the form of restricted stock units, restricted stock awards, non-qualified stock options, performance shares, incentive stock options and performance units. In May 2013, our shareholders approved an increase of 1,030,000 in the number shares authorized to be issued under the LTIP.
	Pursuant to terms of the LTIP, we have issued to eligible participants restricted stock units, performance share awards and stock only stock appreciation rights (“SOSARs”).
	Restricted Stock Units (“RSU”) and Performance Share Awards (“PSAs”) Awards of RSUs and PSAs are made under our LTIP. The vesting of RSUs is based solely on the passage of time, generally on a graded scale over a three, four, and five-year period. PSAs are issued annually and cliff vest on December 31 of the third year following the grant assuming the achievement of predetermined, three-year cumulative performance targets. The performance measures include a minimum, target and maximum performance level providing the grantees an opportunity to receive more or less shares than targeted depending on actual financial performance. For both RSUs and PSAs, the grant date fair value of the awards, which is equal to the closing price per common share on the date of the award, is used to determine the amount of expense to be recognized over the applicable service period. Settlement of RSUs and PSAs will be made in shares of our common stock currently held in treasury.
	The following table summarizes RSU and PSA activity during the first nine months of 2013 and 2012:

	Less current portion			—		—
	Long-term debt, net of current portion		$	438,581	$	250,000
	On November 21, 2011, we entered into an amendment to our revolving credit agreement with a consortium of banks (the “Revolving Credit Facility”) which increased the amount available for borrowing to $350 million, extended the maturity of the facility to November 21, 2016, and instituted a lower interest rate pricing grid.
	For all U.S. dollar denominated borrowings under the Revolving Credit Facility, the borrowing rate is, at our option, (a) the bank’s base rate which is equal to the greater of i) the prime rate; ii) the federal funds rate plus 50 basis points plus an applicable spread ranging from 25 basis points to 125 basis points based on our corporate credit ratings determined by Standard & Poor’s Rating Services and Moody’s Investor Service, Inc. (the “Corporate Credit Rating”); or iii) the daily Euro-rate plus 100 basis points; or (b) the daily Euro-rate plus an applicable margin ranging from 125 basis points to 225 basis points based on the Corporate Credit Rating. For non-US dollar denominated borrowings, interest is based on (b) above.
	The Revolving Credit Facility contains a number of customary covenants for financings of this type that, among other things, restrict our ability to dispose of or create liens on assets, incur additional indebtedness, repay other indebtedness, limit certain intercompany financing arrangements, make acquisitions and engage in mergers or consolidations. We are also required to comply with specified financial tests and ratios including: i) maximum net debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”) ratio; and ii) a consolidated EBITDA to interest expense ratio. A breach of these requirements would give rise to certain remedies under the Revolving Credit Facility, among which are the termination of the agreement and accelerated repayment of the outstanding borrowings plus accrued and unpaid interest under the credit facility.
	On October 3, 2012, we completed an offering of $250 million aggregate principal amount of 5.375% Senior Notes due 2020 (the “5.375% Notes”). The 5.375% Notes are fully and unconditionally guaranteed, jointly and severally, by PHG Tea Leaves, Inc., Mollanvick, Inc., The Glatfelter Pulp Wood Company, and Glatfelter Holdings, LLC (the “Guarantors”).
	Unamortized deferred debt issuance costs related to the offering of the 5.375% Notes totaled $4.3 million and $4.8 million as of September 30, 2013 and December 31, 2012, respectively, and are reported under the caption “Other assets” in the accompanying condensed consolidated balance sheets. The deferred costs are being amortized on a straight line basis over the life of the 5.375% Notes.
	Interest on the 5.375% Notes is payable semiannually in arrears on April 15 and October 15.
	The 5.375% Notes are redeemable, in whole or in part, at anytime on or after October 15, 2016 at the redemption prices specified in the applicable Indenture. Prior to October 15, 2016, we may redeem some or all of the Notes at a “make-whole” premium as specified in the Indenture. These Notes and the guarantees of the notes are senior obligations of the Company and the Guarantors, respectively, rank equally in right of payment with future senior indebtedness of the Company and the Guarantors and will mature on October 15, 2020.
	The 5.375% Notes contain cross default provisions that could result in all such notes becoming due and payable in the event of a failure to repay debt outstanding under the Revolving Credit Agreement at maturity or a default under the Revolving Credit Agreement that accelerates the debt outstanding thereunder. As of September 30, 2013, we met all of the requirements of our debt covenants.
	On April 11, 2013, Glatfelter Gernsbach GmbH & Co. KG (“Gernsbach”), a wholly-owned subsidiary of ours, entered into an agreement with IKB Deutsche Industriebank AG, Düsseldorf (“IKB”), pursuant to which Gernsbach borrowed from IKB approximately €42.7 million (or $57.6 million) aggregate principal amount (the “IKB Loan”).
	The IKB Loan, guaranteed in full by us, is repayable in 32 quarterly installments beginning on June 30, 2015 and ending on March 31, 2023 and will bear interest at a rate of 2.05% per annum. Interest on the IKB Loan or portion thereof is payable quarterly in each year of the term of the loan with interest accruing from the date the loan or portion thereof is drawn.
	The IKB Loan provides for representations, warranties and covenants customary for financings of this type. The financial covenants contained in the IBK Loan, which relate to the minimum ratio of consolidated EBITDA to consolidated interest expense and the maximum ratio of consolidated total net debt to consolidated adjusted EBITDA, will be calculated by reference to our Amended and Restated Credit Agreement, dated November 21, 2011.
	As of September 30, 2013 and December 31, 2012, we had $5.2 million of letters of credit issued to us by certain financial institutions. The letters of credit, which reduce amounts available under our revolving credit facility, primarily provide financial assurances for the benefit of certain state workers compensation insurance agencies in conjunction with our self-insurance program. We bear the credit risk on this amount to the extent that we do not comply with the provisions of certain agreements. No amounts are outstanding under the letters of credit.

Asset Retirement Obligation	'
	13	ASSET RETIREMENT OBLIGATION
	During 2008, we recorded $11.5 million, net present value, of asset retirement obligations related to the legal requirement to close several lagoons at the Spring Grove, PA facility. Historically, lagoons were used to dispose of residual waste material. Closure of the lagoons, which is expected to be completed in 2016, will be accomplished by filling the lagoons, installing a non-permeable liner which will be covered with soil to construct the required cap over the lagoons. The amount referred to above, in addition to upward revisions, was accrued with a corresponding increase in the carrying value of the property, equipment and timberlands caption on the consolidated balance sheet. The amount capitalized is being amortized as a charge to operations on the straight-line basis in relation to the expected closure period. Following is a summary of activity recorded during the first nine months of 2013 and 2012:

Financial Derivatives and Hedging Activities	'
	15	FINANCIAL DERIVATIVES AND HEDGING ACTIVITIES
	As part of our overall risk management practices, we enter into financial derivatives primarily designed to either i) hedge foreign currency risks associated with forecasted transactions – “cash flow hedges”; or ii) mitigate the impact that changes in currency exchange rates have on intercompany financing transactions and foreign currency denominated receivables and payables – “foreign currency hedges.”
	Derivatives Designated as Hedging Instruments - Cash Flow Hedges We use currency forward contracts as cash flow hedges to manage our exposure to fluctuations in the currency exchange rates on certain forecasted production costs expected to be incurred over a maximum of twelve months. Currency forward contracts involve fixing the EUR-USD exchange rate or USD-CAD for delivery of a specified amount of foreign currency on a specified date.
	We designate certain currency forward contracts as cash flow hedges of forecasted raw material purchases or certain production costs with exposure to changes in foreign currency exchange rates. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is deferred as a component of accumulated other comprehensive income in the accompanying condensed consolidated balance sheets and is subsequently reclassified into costs of products sold in the period that inventory produced using the hedged transaction affects earnings. The ineffective portion of the change in fair value of the derivative is recognized directly to earnings and reflected in the accompanying condensed consolidated statements of income as non-operating income (expense) under the caption “Other-net.”
	We had the following outstanding derivatives that were used to hedge foreign exchange risks associated with forecasted transactions and designated as hedging instruments:
	In thousands		September 30			December 31
			2013			2012
	Derivative		Buy Notional
	Sell / Buy
	Euro / U.S. dollar			25,275			27,003
	U.S. dollar / Canadian dollar			13,317			12,369
	These contracts have maturities of twelve months or less.
	Derivatives Not Designated as Hedging Instruments—Foreign Currency Hedges We also enter into forward foreign exchange contracts to mitigate the impact changes in currency exchange rates have on balance sheet monetary assets and liabilities. None of these contracts are designated as hedges for financial accounting purposes and, accordingly, changes in value of the foreign exchange forward contracts and in the offsetting underlying on-balance-sheet transactions are reflected in the accompanying condensed statements of income under the caption “Other – net.”
	The following sets forth derivatives used to mitigate the impact changes in currency exchange rates have on balance sheet monetary assets and liabilities:

	The amounts set forth in the table above represent the net asset or liability giving effect to rights of offset with each counterparty. The effect of netting the amounts presented above did not have a material effect on our consolidated financial position.
	The following table summarizes the amount of income or (loss) from derivative instruments recognized in our results of operations for the periods indicated and the line items in the accompanying condensed consolidated statements of income where the results are recorded:
			Three months ended						Nine months ended
			September 30						September 30
	In thousands		2013			2012			2013			2012
	Designated as hedging:
	Forward foreign currency exchange contracts:
	Effective portion – cost of products sold		$	(384	)	$	715		$	(641	)	$	1,832
	Ineffective portion – other – net			49			18			74			244
	Not designated as hedging:
	Forward foreign currency exchange contracts:
	Other – net		$	(348	)	$	(684	)	$	(794	)	$	(290	)
	The impact of activity not designated as hedging was substantially all offset by the remeasurement of the underlying on-balance sheet item.
	The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).
	The fair values of the foreign exchange forward contracts are considered to be Level 2. Foreign currency forward contracts are valued using foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to present value. Contracts in a gain position are recorded in the condensed consolidated balance sheets under the caption “Prepaid expenses and other current assets” and the value of contracts in a loss position is recorded under the caption “Other current liabilities.”
	A rollforward of fair value amounts recorded as a component of accumulated other comprehensive income is as follows:
	In thousands		2013			2012
	Balance at January 1,		$	(599	)	$	1,649
	Deferred (losses) gains on cash flow hedges			(778	)		663
	Reclassified to earnings			641			(1,832	)
	Balance at September 30,		$	(736	)	$	480
	We expect substantially all of the amounts recorded as a component of accumulated other comprehensive income will be realized in results of operations within the next twelve months and the amount ultimately recognized will vary depending on actual market rates.
	Credit risk related to derivative activity arises in the event a counterparty fails to meet its obligations to us. This exposure is generally limited to the amounts, if any, by which the counterparty’s obligations exceed our obligation to them. Our policy is to enter into contracts only with financial institutions which meet certain minimum credit ratings.

	Fox River – Neenah, Wisconsin
	Background. We have significant uncertainties associated with environmental claims arising out of the presence of polychlorinated biphenyls (“PCBs”) in sediments in the lower Fox River, on which our former Neenah facility was located, and in the Bay of Green Bay Wisconsin (collectively, the “Site”). The United States, the State of Wisconsin, and two Indian tribes (collectively, the “Governments”) seek to require (a) a cleanup of the Site (“response actions”), (b) reimbursement of cleanup costs (“response costs”), and (c) natural resource damages (“NRDs”). They claim that we, together with seven other entities that have been formally notified that they are potentially responsible parties (“PRPs”) under CERCLA for response costs or NRDs, are jointly and severally responsible under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA” or “Superfund”) for those response actions, response costs, and NRDs, all of which may total in excess of $1 billion.
	The PRPs consist of us, Appvion, Inc. (formerly known as Appleton Papers Inc.), CBC Coating, Inc. (formerly known as Riverside Paper Corporation), Georgia-Pacific Consumer Products, L.P. (formerly known as Fort James Operating Company), Menasha Corporation, NCR Corporation (“NCR”), U.S. Paper Mills Corp., and WTM I Company.
	The Governments have identified manufacturing and recycling of NCR®-brand carbonless copy paper as the principal source of the PCBs in sediments at the Site. Our predecessor, the Bergstrom Paper Company, and later we operated a deinking paper mill in Neenah, Wisconsin. This mill received NCR®-brand carbonless copy paper in its furnish and discharged PCBs to Little Lake Butte des Morts, an impoundment of the river at the upstream end of the Site.
	The United States Environmental Protection Agency (“EPA”) has divided the Site into five “operable units”, including the most upstream (“OU1”) and four downstream reaches of the river and bay (“OU2-5”). OU1 extends from primarily Lake Winnebago to the dam at Appleton, and is comprised of Little Lake Butte des Morts. The Neenah Facility discharged its wastewater into this portion of the site.
	We have resolved our liability for response actions and response costs associated with the permanent cleanup of Little Lake Butte des Morts through a consent decree, and amendments, entered in United States v. P.H. Glatfelter Co., No. 2:03-cv-949-LA (E.D. Wis.). Together with WTM I Company and with assistance from Menasha Corporation, we have completed that cleanup except for on-going operation and maintenance.
	In November 2007, the EPA issued a unilateral administrative order for remedial action (“UAO”) to us and to seven other respondents directing us to implement the cleanup of the Site downstream of Little Lake Butte des Morts. Since that time, the district court has held that one of the respondents, Appvion, is not liable for this Site. In addition, the United States and the State of Wisconsin have entered into a settlement with another respondent, Georgia-Pacific LLP (“GP”), limiting GP’s responsibility to the downstream-most three miles of the river. Work has proceeded to implement the UAO, mostly funded by NCR and its indemnitors.
	In January 2008, two of the UAO respondents, NCR and Appleton Papers Inc. (now known as Appvion), brought two actions, consolidated under the caption Appleton Papers Inc. v. George A. Whiting Paper Co., No. 2:08-cv-16-WCG (E.D. Wis.) (“Whiting Litigation”), that ultimately involved us and more than two dozen parties in litigation to allocate among the parties the responsibility for response actions, response costs, and NRDs for this Site. Most of the parties responsible for relatively small discharges of PCBs settled with the Governments, resolving their liability. On June 27, 2013, the district court entered a final judgment that (a) neither NCR nor Appvion may pursue any other party for contribution, (b) NCR owes us and the other non-settling parties “full contribution” for any amounts we may have to pay on account of response actions or response costs downstream of Little Lake Butte des Morts or on account of NRDs, (c) NCR is not liable for response costs, response actions, or NRDs in Little Lake Butte des Morts, and (d) NCR owes us reimbursement of $4.28 million in costs we incurred in the past. NCR and Appvion have appealed that judgment. We have filed a cross-appeal of that judgment (as have several other defendants), challenging those portions of the judgment with which we disagree, including the ruling that NCR is not liable for response costs, response actions, or NRDs in Little Lake Butte des Morts. Until the Whiting Litigation judgment is affirmed on appeal, all past and future costs or damages incurred by any person remain the subject of litigation against us.
	In October 2010, the United States and the State of Wisconsin sued us and thirteen other defendants to recover an injunction requiring the UAO respondents to complete the response actions required by the UAO and all parties to reimburse past and future response costs incurred by the Governments as well as to pay NRDs. That case is captioned United States v. NCR Corp., No. 1:10-cv-910-WCG (E.D. Wis.) (“Government Action”). To date, litigation of the Government Action has been limited to the United States’ claim against the UAO respondents for a mandatory injunction to require implementation of the remaining work under the UAO, that is, completion of the remedy in the 33 miles of the river downstream of Little Lake Butte des Morts. Following a trial in December 2012, on May 1, 2013, the district court granted that injunction (“May 2013 Order”). The May 2013 Order directs the Company “jointly and severally” along with three other defendants that are also enjoined (NCR, WTM I Company, and Menasha Corporation) to comply with the UAO. An accompanying declaratory judgment declares the Company and those three defendants jointly and severally liable with three additional defendants (Georgia-Pacific, LLP, U.S. Paper Mills, Inc., and CBC Coatings, Inc.) that have entered into agreements with the United States governing those parties’ compliance with the UAO. The district court has denied NCR’s motion to require us to contribute to compliance with the injunction. We have appealed the May 2013 Order, as have NCR, WTM I, and Menasha.
	Cost estimates. Estimates of the Site remediation change over time as we, or others, gain additional data and experience at the Site. In addition, disagreement exists over the likely costs for some of this work. Based upon estimates made by the Governments and independent estimates commissioned by various potentially responsible parties, we have no reason to disagree with the Governments’ assertion that total past and future response costs and NRDs at this site may exceed $1 billion and that $1.5 billion is a reasonable “outside estimate.” Much of that amount has already been incurred. As described below, some of that amount is NRDs. The parties implementing the response action under the UAO in the downstream part of the river estimate the cost of work being done in 2013 and the future cost of work yet to be done totals approximately $360 million. The Governments seek to have that work done at a rate estimated to cost approximately $70 million each year from 2013 through 2016, and at lower rate afterward.
	NRDs. The Governments’ NRD assessment documents claimed that we are jointly and severally responsible for NRDs with a value between $176 million and $333 million. The Governments now claim that this range should be inflated to 2009 dollars and then certain unreimbursed past assessment costs should be added, so that the range of their claim would be $287 million to $423 million. We deny liability for most of these NRDs and believe that even if anyone is liable, that we are not jointly and severally liable for the full amount. The May 2013 Order does not determine whether liability for NRDs would be joint and several. Moreover, we believe that the Natural Resource Trustees may not legally pursue this claim at this late date, as the limitations period for NRD claims is three years from discovery.
	Reserves for the Site. As of September 30, 2013, our reserve for the Site, including our remediation and ongoing monitoring obligations in Little Lake Butte des Morts, our share of remediation of the rest of the Site, NRDs associated with PCB contamination at the Site and all pending, threatened or asserted and unasserted claims against us relating to PCB contamination at the Site totaled $16.3 million. Of our total reserve for the Fox River, $0.1 million is recorded in the accompanying condensed consolidated balance sheets under the caption “Environmental liabilities” and the remainder is recorded under the caption “Other long term liabilities.”
	Although we believe that amounts already funded by us and WTM I to implement the Little Lake Butte des Morts remedy are adequate and no payments have been required since January 2009, there can be no assurance that these amounts will in fact suffice. WTM I has filed a bankruptcy petition in the Bankruptcy Court in Richmond; accordingly, there can be no assurance that WTM I will be able to fulfill its obligation to pay half of any additional costs, if required.
	We do not believe that we will be allocated a significant percentage share of liability in any final equitable allocation of the response costs and NRDs. The accompanying consolidated financial statements do not include reserves for defense costs for the Whiting Litigation, the Government Action, or any future defense costs related to our involvement at the Site, which could be significant.
	In setting our reserve for the Site, we have assessed our legal defenses, including our successful defenses to the allegations made in the Whiting Litigation and the determination in the Whiting Litigation that NCR owes us “full contribution” for response costs and NRDs that we may become obligated to pay except in OU1, and assumed that we will not bear the entire cost of remediation or damages to the exclusion of other known parties at the Site, who are also potentially jointly and severally liable. The existence and ability of other parties to participate has also been taken into account in setting our reserve, and is generally based on our evaluation of recent publicly available financial information on certain of the responsible parties and any known insurance, indemnity or cost sharing agreements between responsible parties and third parties. In addition, our assessment is based upon the magnitude, nature, location and circumstances associated with the various discharges of PCBs to the river and the relationship of those discharges to identified contamination. We will continue to evaluate our exposure and the level of our reserves, including, but not limited to, our potential share of the costs and NRDs, if any, associated with the Site.
	The amount and timing of future expenditures for environmental compliance, cleanup, remediation and personal injury, NRDs and property damage liabilities cannot be ascertained with any certainty due to, among other things, the unknown extent and nature of any contamination, the response actions that may ultimately be required, the availability of remediation equipment and landfill space, and the number and financial resources of any other PRPs.
	Other Information. The Governments have published studies estimating the amount of PCBs discharged by each identified potentially responsible party’s (“PRP’s”) facility to the lower Fox River and Green Bay. These reports estimate our Neenah mill’s share of the mass of PCBs discharged to be as high as 27%. The district court in its May 2013 Order found the discharge mass estimates used in these studies not to be accurate. We believe that the Neenah mill’s absolute and relative contribution of PCB mass is significantly lower than the estimates set forth in these studies. The trial court in the Government Action has found that the Neenah mill discharged an unknown amount of PCBs.
	In any event, based upon the rulings in the Whiting Litigation and the Government Action, neither of which endorsed an equitable allocation in proportion to the mass of PCBs discharged, we continue to believe that an allocation in proportion to mass of PCBs discharged would not constitute an equitable allocation of the potential liability for the contamination at the Fox River. We contend that other factors, such as the location of contamination, the location of discharge, and a party’s role in causing discharge, must be considered in order for the allocation to be equitable.
	In the 1990s, we entered into interim cost-sharing agreements with six of the other PRPs, which provided for those PRPs to share certain costs relating to scientific studies of PCBs discharged at the Site (“Interim Cost Sharing Agreements”). These Interim Cost Sharing Agreements do not establish the final allocation of remediation costs incurred at the Site. Based upon our evaluation of the rulings in the Whiting Litigation as well as the volume, nature and location of the various discharges of PCBs at the Site and the relationship of those discharges to identified contamination, we believe our allocable share of liability at the Site is less than our share of costs under the Interim Cost Sharing Agreements.
	Range of Reasonably Possible Outcomes. Our analysis of the range of reasonably possible outcomes is derived from all available information, including but not limited to decisions of the courts, official documents such as records of decision, discussions with the United States and other parties, as well as legal counsel and engineering consultants. Based on our analysis of the current records of decision and cost estimates for work to be performed at the Site, we believe that it is reasonably possible that our costs associated with the Fox River matter may exceed our cost estimates and the aggregate amounts accrued for the Fox River matter by amounts that are insignificant or that could range up to $275 million over an undeterminable period that could range beyond 10 years. We believe that the likelihood of an outcome in the upper end of the monetary range is significantly less than other possible outcomes within the range and that the possibility of an outcome in excess of the upper end of the monetary range is remote. The rulings in our favor in the Whiting Litigation, if sustained on appeal, suggest that outcomes in the upper end of the monetary range have become somewhat less likely, while adverse rulings on some issues in the Whiting Litigation and the Government Action and increases in cost estimates for some of the work may make an outcome in the upper end of the range more likely. The Company also believes that the effect of reading the Whiting Litigation decisions together with the May 2013 Order requires the ongoing compliance with the UAO to be funded by NCR, or to the extent that the Company is required to provide any such funding, that NCR will be required to reimburse the Company. There can be no assurance, however, that the May 2013 Order will not have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operation.
	Summary. Our current assessment is that we will be able to manage this environmental matter without a long-term, material adverse impact on the Company. This matter could, however, at any particular time or for any particular year or years, have a material adverse effect on our consolidated financial position, liquidity and/or results of operations or could result in a default under our debt covenants. Moreover, there can be no assurance that our reserves will be adequate to provide for future obligations related to this matter, that our share of costs and/or damages will not exceed our available resources, or that those obligations will not have a long-term, material adverse effect on our consolidated financial position, liquidity or results of operations. Should a court grant the United States or the State of Wisconsin relief that requires us individually either to perform directly or to contribute significant amounts towards remedial action downstream of Little Lake Butte des Morts or to NRDs, those developments could have a material adverse effect on our consolidated financial position, liquidity and results of operations and might result in a default under our loan covenants.

	Results of individual business units are presented based on our management accounting practices and management structure. There is no comprehensive, authoritative body of guidance for management accounting equivalent to accounting principles generally accepted in the United States of America; therefore, the financial results of individual business units are not necessarily comparable with similar information for any other company. The management accounting process uses assumptions and allocations to measure performance of the business units. Methodologies are refined from time to time as management accounting practices are enhanced and businesses change. The costs incurred by support areas not directly aligned with the business unit are allocated primarily based on an estimated utilization of support area services or are included in “Other and Unallocated” in the Business Unit Performance table.
	Management evaluates results of operations of the business units before pension expense, certain corporate level costs, and the effects of certain gains or losses not considered to be related to the core business operations. Management believes that this is a more meaningful representation of the operating performance of its core businesses, the profitability of business units and the extent of cash flow generated from these core operations. Such amounts are presented under the caption “Other and Unallocated.” This presentation is aligned with the management and operating structure of our company. It is also on this basis that the Company’s performance is evaluated internally and by the Company’s Board of Directors.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation The unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Glatfelter and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
	We prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”). In our opinion, the financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. When preparing these financial statements, we have assumed that you have read the audited consolidated financial statements included in our 2012 Annual Report on Form 10-K (“2012 Form 10-K”).
Accounting Estimates	'
	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes that actual results may differ from those estimates and assumptions.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements In February 2013, the FASB issued ASU 2013-02 –“Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which requires new disclosures about items reclassified out of accumulated other comprehensive income. We adopted the requirements of this standard in the first quarter of 2013.
