Basis Of Presentation [Abstract]
Basis Of Presentation	In the opinion of management, the accompanying condensed consolidated financial statements of Tredegar Corporation and its subsidiaries (“Tredegar,” “the Company,” “we,” “us” or “our”) contain all adjustments necessary to state fairly, in all material respects, Tredegar’s consolidated financial position as of March 31, 2021, the consolidated results of operations for the three months ended March 31, 2021 and 2020, the consolidated cash flows for the three months ended March 31, 2021 and 2020, and the consolidated changes in shareholders’ equity for the three months ended March 31, 2021 and 2020, in accordance with U.S. generally accepted accounting principles (“GAAP”). All such adjustments, unless otherwise detailed in the notes to the condensed consolidated financial statements, are deemed to be of a normal, recurring nature. The Company operates on a calendar fiscal year except for the Aluminum Extrusions segment, which operates on a 52/53-week fiscal year basis. As such, the fiscal first quarter for 2021 and 2020 for this segment references 13-week periods ended March 28, 2021 and March 29, 2020, respectively. The Company does not believe the impact of reporting the results of this segment as stated above is material to the consolidated financial results. The Company may fund or receive cash from the Aluminum Extrusions segment based on Aluminum Extrusion’s cash flows from operations during the intervening period from Aluminum Extrusion’s fiscal quarter end and the Company’s fiscal quarter end. There was no intercompany funding with Aluminum Extrusions between March 28, 2021 and March 31, 2021. As of December 31, 2020, the Company’s cash and cash equivalents declined by $3.8 million since the Company made payments to the Aluminum Extrusions segment to fund its working capital during the intervening period. The financial position data as of December 31, 2020 that is included herein was derived from the audited consolidated financial statements provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”) but does not include all disclosures required by GAAP. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the 2020 Form 10-K. On October 30, 2020, the Company completed the sale of its personal care films business (“Personal Care Films”), which was part of its PE Films segment. The transaction excluded the packaging film lines and related operations located at the Pottsville, Pennsylvania manufacturing site (“Pottsville Packaging”), which are now being reported within the Surface Protection component of PE Films. All historical results for Personal Care Films have been presented as discontinued operations. On December 31, 2020, the Company completed the sale of Bright View Technologies, which was part of its PE Films segment. The sale did not represent a strategic shift nor did it have a major effect on the Company's historical and ongoing operations, thus all financial information for Bright View Technologies has been presented in continuing operations. The results of operations for the three months ended March 31, 2021, are not necessarily indicative of the results to be expected for the full year. Accounting Standards Adopted: In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2019-12, which simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, hybrid taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. In the first quarter of 2021, the Company adopted ASU 2019-12 which did not have a material impact on the Company's consolidated financial statements.

Impairment Goodwill Impairment (Notes)	Mar. 31, 2021
Goodwill Impairment Disclosure [Abstract]
Goodwill Disclosure [Text Block]	The Company assesses its long-lived assets for impairment when events and circumstances indicate that the carrying amount of the assets may not be recoverable. Long-lived assets consist primarily of buildings, machinery and equipment. During the three months ended March 31, 2021, the Company did not identify any indicators of impairment for long-lived assets. The Company annually assesses goodwill for impairment on December 1st of each year or more frequently when events or circumstances indicate that the carrying amount of a reporting unit that includes goodwill exceeds its fair value. The Company evaluated whether triggering events occurred during the three months ended March 31, 2021 and 2020 for all reporting units that include goodwill and determined that triggering events did occur during the first three months of 2020 for the Aluminum Extrusions’ reporting units created as a result of acquisitions in 2012 (“AACOA”) and in 2017 (“Futura”). As a result of the impairment testing performed, the Company recognized a goodwill impairment charge of $13.7 million ($10.5 million after taxes), which represented the entire amount of goodwill associated with the AACOA reporting unit. No impairment was identified for Futura. The Company continues to monitor developments related to the COVID-19 pandemic and may perform updated analyses during 2021 as necessary.

In July 2019, the Company committed to a plan to close its manufacturing facility in Lake Zurich, Illinois, which historically was reported by the Company within the Personal Care Films component of its PE Films segment. In 2020, the held for sale criteria was met since the Company expects the sale of the facility to be completed within one year. The disposal group carrying value of $4.6 million consists of land, building, and building improvements and is reported in "Prepaid expenses and other" in the consolidated balance sheet. These assets were not included as part of the sale of Personal Care Films.

Earnings Per Share [Abstract]

Earnings Per Share

Basic earnings per share is computed by dividing net income (loss) from continuing and discontinued operations by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net

income (loss) from continuing and discontinued operations by the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows:


	Three Months Ended
	March 31,
(In thousands)		2021	2020
Weighted average shares outstanding used to compute basic earnings per share		33,406	33,313
Incremental dilutive shares attributable to stock options and restricted stock		238	—
Shares used to compute diluted earnings per share		33,644	33,313

Incremental shares attributable to stock options and restricted stock are computed under the treasury stock method using the average market price during the related period. The average out-of-the-money options to purchase shares that were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 411,516 as of March 31, 2021. The Company had a net loss from continuing operations for the three months ended March 31, 2020, so there is no dilutive impact for such shares. If the Company had reported net income from continuing operations for the three months ended March 31, 2020, average out-of-the-money options to purchase shares that would have been excluded from the calculation of incremental shares attributable to stock options and restricted stock were 682,696.

Investments, Debt and Equity Securities [Abstract]
Investments and Other Noncurrent Assets	he Company's aggregate investment of $7.5 million, for an approximate 19% ownership interest, in kaleo, Inc. (“kaléo”), a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions, is accounted for under the fair value method in the consolidated financial statements.The estimated fair value of the Company’s investment was $35.0 million as of March 31, 2021 and $34.6 million as of December 31, 2020. kaléo’s stock is not publicly traded. The ultimate value of the Company’s ownership interest in kaléo could be materially different from the estimated fair value and will ultimately be determined and realized only if and when a liquidity event occurs. Amounts recognized associated with the Company’s investment in kaléo are included in “Other income (expense), net” in the consolidated statements of income and separately stated in the net sales and earnings before interest, taxes, depreciation and amortization ("EBITDA") from ongoing operations by segment table in Note 11. The Company estimated the fair value of its investment in kaléo at March 31, 2021 by: (i) computing the weighted average estimated enterprise value (“EV”) utilizing both the discounted cash flow method (the “DCF Method”) and the application of a market multiple to EBITDA (the “EBITDA Multiple Method”), (ii) applying adjustments for any surplus or deficient working capital and estimates of contingent liabilities, (iii) adding cash and cash equivalents, (iv) subtracting interest-bearing debt, (v) subtracting a private company liquidity discount estimated at approximately 20% at March 31, 2021 (versus 20% at both December 31, 2020 and March 31, 2020) of the net result of (i) through (iv), and (vi) applying liquidation preferences and fully diluted ownership percentages to the estimated equity value computed in (i) through (v). The Company’s estimate of kaléo’s EV as of March 31, 2021 and December 31, 2020 was determined by weighting the EBITDA Multiple Method by 20% and the DCF Method by 80%. A heavier weighting towards the DCF Method was used since kaléo’s projections better reflect ongoing pricing pressures and expected changes in market access. The DCF Method projections rely on numerous assumptions and Level 3 inputs. In addition, there are various regulatory and legal enforcement efforts, including an ongoing Department of Justice investigation related to kaléo’s discontinued Evzio business, which could have a material adverse effect on kaléo’s business that require assessment in any valuation method applied.

Derivative Financial Instruments

Summary of Derivative Instruments [Abstract]

Derivative Financial Instruments

Tredegar uses derivative financial instruments for the purpose of hedging margin exposure from fixed-price forward sales contracts in Aluminum Extrusions and exposure from currency volatility that exists as part of ongoing business operations in Flexible Packaging Films. These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the consolidated balance sheet at fair value. The fair value of derivative instruments recorded on the consolidated balance sheets. If individual derivative instruments with the same counterparty can be settled on a net basis, the Company records the corresponding derivative fair values as a net asset or net liability.

In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the future sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, Aluminum Extrusions enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled purchases for the firm sales commitments. The fixed-price firm sales commitments and related hedging instruments generally have durations of not more than 12 months. The notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $10.4 million (10.5 million pounds of aluminum) at March 31, 2021 and $12.1 million (13.0 million pounds of aluminum) at December 31, 2020.

The table below summarizes the location and gross amounts of aluminum futures contract fair values (Level 2) in the consolidated balance sheets as of March 31, 2021 and December 31, 2020:


	March 31, 2021			December 31, 2020
(In thousands)	Balance Sheet Account	Fair Value		Balance Sheet Account	Fair Value
Derivatives Designated as Hedging Instruments
Asset derivatives: Aluminum futures contracts	Prepaid expenses and other	$	2,413	Prepaid expenses and other	$	1,560
Liability derivatives: Aluminum futures contracts	Accrued expenses	—		Accrued expenses	(22)
Net asset		$	2,413		$	1,538

In the event that a counterparty to an aluminum fixed-price forward sales contract chooses not to take delivery of its aluminum extrusions, the customer is contractually obligated to compensate Aluminum Extrusions for any losses on the related aluminum futures and/or forward contracts through the date of cancellation.

The Company's earnings are exposed to foreign currency exchange risk primarily through the translation of the financial statements of subsidiaries that have a functional currency other than the U.S. Dollar. The Company estimates that the net mismatch translation exposure for the Flexible Packaging Film's business unit in Brazil (“Terphane Ltda.”) of its sales and raw materials quoted or priced in U.S. Dollars and its variable conversion, fixed conversion and sales, general and administrative costs (before depreciation and amortization) quoted or priced in Brazilian Real ("R$") is annual net costs of R$119 million.

Terphane Ltda. has the following outstanding foreign exchange average forward rate contracts to purchase Brazilian Real and sell U.S. Dollars:


USD Notional Amount (000s)	Average Forward Rate Contracted on USD/BRL	R$ Equivalent Amount (000s)	Applicable Month	Estimated % of Terphane Ltda. R$ Operating Cost Exposure Hedged



$1,320	5.4765	R$7,229	Apr-21	73%
$1,285	5.4778	R$7,039	May-21	71%
$1,395	5.4882	R$7,656	Jun-21	77%
$1,450	5.4945	R$7,967	Jul-21	80%
$1,430	5.4993	R$7,864	Aug-21	79%
$1,520	5.5105	R$8,376	Sep-21	84%
$1,400	5.5100	R$7,714	Oct-21	78%
$1,495	5.5224	R$8,256	Nov-21	83%
$1,170	5.5060	R$6,442	Dec-21	65%
$12,465	5.4988	R$68,543		77%

These foreign currency exchange contracts have been designated and qualify as cash flow hedges of Terphane Ltda.’s forecasted sales to customers quoted or priced in U.S. Dollars over that period. By changing the currency risk associated with these U.S. Dollar sales, the derivatives have the effect of offsetting operating costs quoted or priced in Brazilian Real and decreasing the net exposure to Brazilian Real in the consolidated statements of income. Pre-tax accumulated losses of $0.4 million related to the net fair value of the open forward contracts is reported in accumulated other comprehensive income (loss) as of March 31, 2021.

The table below summarizes the location and gross amounts of foreign currency forward contract fair values (Level 2) in the consolidated balance sheets as of March 31, 2021 and December 31, 2020:


	March 31, 2021			December 31, 2020
(In thousands)	Balance Sheet Account	Fair Value		Balance Sheet Account	Fair Value
Derivatives Designated as Hedging Instruments
Asset derivatives: Foreign currency forward contracts	Prepaid expenses and other	$	—	Prepaid expenses and other	$	853
Liability derivatives: Foreign currency forward contracts	Accrued expenses	(468)		Accrued expenses	(466)
Net asset (liability)		$	(468)		$	387

These derivative contracts involve elements of market risk that are not reflected on the consolidated balance sheet, including the risk of dealing with counterparties and their ability to meet the terms of the contracts. The counterparties to any forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to any aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to the best and most credit-worthy customers. The counterparties to the Company’s foreign currency cash flow hedge contracts are major financial institutions.

The pretax effect on net income (loss) and other comprehensive income (loss) of derivative instruments classified as cash flow hedges and described in the previous paragraphs for the three month periods ended March 31, 2021 and 2020 is summarized in the table below:


	Cash Flow Derivative Hedges
	Three Months Ended March 31,
	Aluminum Futures Contracts				Foreign Currency Forwards
(In thousands)	2021		2020		2021				2020
Amount of pretax gain (loss) recognized in other comprehensive income (loss)	$	1,515	$	(1,594)	$	—	$	(1,283)	$	—	$	(4,824)
Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion)	Cost of sales		Cost of sales		Cost of sales		Selling, general & admin		Cost of sales		Selling, general & admin
Amount of pretax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (effective portion)	$	640	$	(640)	$	17	$	(2)	$	15	$	(794)

As of March 31, 2021, the Company expects $1.8 million of unrealized after-tax gains on derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months. For the three month periods ended March 31, 2021 and 2020, net gains or losses realized, from previously unrealized net gains or losses on hedges that had been discontinued, were not material.

Retirement Benefits [Abstract]

Pension And Other Post-Retirement Benefits

Tredegar sponsors a noncontributory defined benefit (pension) plan covering certain current and former U.S. employees. As of January 31, 2018, the plan no longer accrued benefits associated with crediting employees for service, thereby freezing all future benefits under the plan. The components of net periodic benefit cost for the pension and other postretirement benefit programs reflected in the consolidated statements of income for the three months ended March 31, 2021 and 2020, are shown below:


	Pension Benefits				Other Post-Retirement Benefits
	Three Months Ended March 31,				Three Months Ended March 31,
(In thousands)	2021		2020		2021		2020
Service cost	$	—	$	—	$	9	$	9
Interest cost	2,102		2,535		50		60
Expected return on plan assets	(2,862)		(2,804)		—		—
Amortization of prior service costs, (gains) losses and net transition asset	4,265		3,814		(24)		(47)
Net periodic benefit cost	$	3,505	$	3,545	$	35	$	22

Pension and other postretirement liabilities were $106.7 million and $111.3 million at March 31, 2021 and December 31, 2020, respectively ($0.7 million included in “Accrued expenses” at March 31, 2021 and December 31, 2020, with the remainder included in “Pension and other postretirement benefit obligations, net” in the consolidated balance sheets). As of December 31, 2020, the required minimum pension contributions were $11.7 million for 2021. The United States government enacted the American Rescue Plan Act of 2021 in March 2021, which, among other impacts, has reduced the Company's 2021 required minimum pension contributions to zero as a result of the Company's election of the interest rate relief used in the present value of the pension obligation and extension of the shortfall amortization period that is used to determine the minimum pension funding requirements.

Tredegar funds its other postretirement benefits on a claims-made basis; for 2021, the Company anticipates the amount will be consistent with amounts paid for the year ended December 31, 2020, or approximately $0.5 million.

Segment Reporting [Abstract]

Segment Reporting

The Company’s business segments are Aluminum Extrusions, PE Films, and Flexible Packaging Films. Information by business segment is reported below. There are no accounting transactions between segments and no allocations to segments. All historical results for Personal Care Films have been presented as discontinued operations. The Surface Protection component of the PE Films segment now includes Pottsville Packaging.

The Company’s reportable segments are based on its method of internal reporting, which is generally segregated by differences in products. Accounting standards for presentation of segments require an approach based on the way the Company organizes the segments for making operating decisions and how the chief operating decision maker (“CODM”) assesses performance. EBITDA from ongoing operations is the key profitability measure used by the CODM (Tredegar’s President and Chief Executive Officer) for purposes of assessing financial performance. The Company uses sales less freight (“net sales”) from continuing operations as its measure of revenues from external customers at the segment level. This measure is separately included in the financial information regularly provided to the CODM.

The following table presents net sales and EBITDA from ongoing operations by segment for the three months ended March 31, 2021 and 2020:

Income Taxes

3 Months Ended

Mar. 31, 2021

Income Tax Disclosure [Abstract]

Income Taxes

Tredegar recorded tax expense of $3.1 million on pretax income from continuing operations of $12.7 million in the first three months of 2021. Therefore, the effective tax rate in the first three months of 2021 was 24.4%, compared to 23.2% in the first three months of 2020. The quarterly effective tax rate is an estimate based on a proration of the components of the Company’s estimated annual effective tax rate and discrete items recorded during the first three months of the year.

The significant differences between the U.S. federal statutory rate and the effective income tax rate for the three months ended March 31, 2021 and 2020 are as follows:


(In thousands, except percentages)	2021				2020
Three Months Ended March 31,	Amount		%		Amount		%
Income tax (benefit) expense at federal statutory rate	$	2,670	21.0	%	$	(5,647)	21.0	%
Foreign rate differences	982		7.7	%	1,027		(3.8)	%
U.S. Tax on Foreign Branch Income	508		4.0	%	702		(2.6)	%
State taxes, net of federal income tax benefit	239		1.9	%	(307)		1.1	%
Stock-based compensation	191		1.5	%	251		(0.9)	%
Non-deductible expenses	155		1.2	%	190		(0.7)	%
Valuation allowance for capital loss carry-forwards	35		0.3	%	40		(0.1)	%
Changes in estimates related to prior year tax provision	—		—	%	(601)		2.2	%
Tax impact of dividend received	(33)		(0.3)	%	—		—	%
Research and development tax credit	(182)		(1.4)	%	(205)		0.8	%
Foreign tax incentives	(1,468)		(11.5)	%	(1,676)		6.2	%
Income tax expense (benefit) at effective income tax rate	$	3,097	24.4	%	$	(6,226)	23.2	%

Tredegar accrues U.S. federal income taxes on unremitted earnings of foreign subsidiaries where required. However, due to changes in the taxation of dividends under the U.S. Tax Cuts and Jobs Act of 2017, Tredegar will only record U.S. federal income taxes on unremitted earnings of its foreign subsidiaries where Tredegar cannot take steps to eliminate any potential tax on future distributions from its foreign subsidiaries.

The Brazilian federal statutory income tax rate is a composite of 34.0% (25.0% of income tax and 9.0% of social contribution on income). Terphane Ltda.’s manufacturing facility in Brazil is the beneficiary of certain income tax incentives that allow for a reduction in the statutory Brazilian federal income tax rate to 15.25% levied on the operating profit on certain of its products. The incentives have been granted for a 13-year period, from the commencement date of January 1, 2015. The benefit from the tax incentives was $1.5 million and $1.7 million in the first three months of 2021 and 2020, respectively.

Tredegar and its subsidiaries file income tax returns in the U.S., various states, and jurisdictions outside the U.S. With exceptions for some U.S. states and non-U.S. jurisdictions, Tredegar and its subsidiaries are no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2017.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
