A reconciliation of the beginning and ending balances of accrued expenses associated with exit and disposal activities and charges associated with asset impairments and reported as “Asset impairments and costs associated with exit and disposal activities, net of adjustments” in the consolidated statements of income for the nine months ended September 30, 2016 is as follows: (In Thousands) Severance Asset Impairments Other (a) Total Balance at January 1, 2016 $ 1,462 $ — $ 405 $ 1,867 Changes in 2016: Charges 1,216 412 727 2,355 Cash spent (833 ) — (593 ) (1,426 ) Charges against assets — (412 ) — (412 ) Balance at September 30, 2016 $ 1,845 $ — $ 539 $ 2,384 (a) Other includes other facility consolidation-related costs associated with the consolidation of North American PE Films manufacturing facilities and other shutdown-related costs associated with the shutdown of the Company’s aluminum extrusions manufacturing facility in Kentland, Indiana. In July 2015, the Company announced its intention to consolidate its domestic production for PE Films by restructuring the operations in its manufacturing facility in Lake Zurich, Illinois. Efforts to transition domestic production from the Lake Zurich manufacturing facility will require various machinery upgrades and equipment transfers to its other manufacturing facilities. Given PE Films’ focus on maintaining product quality and customer satisfaction, the Company anticipates that these activities will be completed in the middle of 2017. Total pre-tax cash expenditures associated with restructuring the Lake Zurich manufacturing facility are expected to be approximately $17 million over the project period, and once complete, annual pre-tax cash cost savings are expected to be approximately $5-6 million. The Company expects to recognize costs associated with the exit and disposal activities of approximately $5-6 million over the project period. Exit and disposal costs include severance charges and other employee-related expenses arising from the termination of employees of approximately $3-4 million and equipment transfers and other facility consolidation-related costs of approximately $2 million . During the same period of time, operating expenses will include the acceleration of approximately $3 million of non-cash depreciation expense for certain machinery and equipment at the Lake Zurich manufacturing facility. Total expenses associated with the North American facility consolidation project were $1.1 million and $3.6 million in the third quarter and first nine months of 2016 , respectively ( $0.6 million and $1.8 million , respectively, included in “Asset impairments and costs associated with exit and disposal activities, net of adjustments” and $0.5 million and $1.8 million , respectively, included in “Cost of goods sold” in the consolidated statements of income). As of September 30, 2016, total expenses incurred since the project began in the third quarter of 2015 were $5.7 million . Total estimated cash expenditures of $16-17 million over the project period include the following: • Cash outlays associated with previously discussed exit and disposal expenses of approximately $5 million , including additional operating expenses of approximately $1 million associated with customer product qualifications on upgraded and transferred production lines; • Capital expenditures associated with equipment upgrades at other PE Films manufacturing facilities in the U.S. of approximately $11 million ; and • Cash incentives of approximately $1 million in connection with meeting safety and quality standards while production ramps down at the Lake Zurich manufacturing facility. Cash expenditures for the North American facility consolidation project were $3.2 million and $9.0 million in the third quarter and first nine months of 2016 , respectively, which includes capital expenditures of $2.6 million and $7.1 million , respectively. As of September 30, 2016, total cash expenditures since the project began in the third quarter of 2015 were $12.5 million , which includes $10.0 million for capital expenditures.

Equity Method Investments and Joint Ventures [Abstract]
Investments	In August 2007 and December 2008, the Company made an aggregate investment of $7.5 million in kaléo, a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions. The mission of kaléo is to provide products that empower patients to confidently take control of their medical conditions. Tredegar’s ownership interest on a fully diluted basis was approximately 19% at September 30, 2016 , and the investment is accounted for under the fair value method. At the time of the initial investment, the Company elected the fair value option over the equity method of accounting since its investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. The estimated fair value of the investment in kaléo (also the carrying value, which is included in “Other assets and deferred charges” in the consolidated balance sheets) was $18.4 million at September 30, 2016 and $18.6 million at December 31, 2015 . Unrealized losses of $1.3 million and $0.2 million were recognized in the third quarter and first nine months of 2016 , respectively (no unrealized gains or losses were recorded in the first nine months of 2015 ). The change in the estimated fair value of the Company’s holding in kaléo in the third quarter of 2016 primarily related to the continuing assessment of market dynamics and pricing uncertainties associated with the reintroduction of the Auvi-Q product, with current quarter changes in the projections being revised to reflect a more conservative outlook. The change in the estimated fair value of the Company’s holding in kaléo in the first nine months of 2016 was primarily attributed to the aforementioned uncertainties about reintroducing Auvi-Q, partially offset by favorable adjustments in the fair value for the passage of time and with the negotiated terms of the termination of Sanofi’s exclusive rights license for Auvi-Q and Allerject in North America and the return of such rights to kaléo. Unrealized gains (losses) associated with this investment are included in “Other income (expense), net” in the consolidated statements of income and separately stated in the net sales and operating profit by segment table in Note 9. Subsequent to its most recent investment (December 15, 2008), and until the next round of financing, the Company believes fair value estimates are based upon Level 3 inputs since there is no secondary market for its ownership interest. Accordingly, until the next round of financing or any other significant financial transaction, value estimates will primarily be based on assumptions relating to achieving product development and commercialization milestones, cash flow projections (projections of sales, costs, expenses, capital expenditures and working capital investment) and discounting of these factors for their high degree of risk. If kaléo does not meet its development and commercialization milestones or there are indications that the amount or timing of its projected cash flows or related risks are unfavorable versus the most recent valuation, or a new round of financing or other significant financial transaction indicates a lower enterprise value, then the Company’s estimate of the fair value of its ownership interest in kaléo is likely to decline. Adjustments to the estimated fair value of this investment will be made in the period upon which such changes can be quantified. In addition to the impact on valuation of the possible changes in assumptions, Level 3 inputs and projections from changes in business conditions, the fair market valuation of the Company’s interest in kaléo is sensitive to changes in the weighted average cost of capital used to discount cash flow projections for the high degree of risk associated with meeting development and commercialization milestones as anticipated. The weighted average cost of capital used in the fair market valuation of Tredegar’s interest in kaléo was 45% at both September 30, 2016 and December 31, 2015 . At September 30, 2016 , the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have increased the fair value of the Company’s interest in kaléo by approximately $5 million , and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of the Company’s interest by approximately $4 million . Had the Company not elected to account for its investment under the fair value method, it would have been required to use the equity method of accounting. The condensed balance sheets for kaléo at September 30, 2016 and December 31, 2015 and condensed statements of operations for the three and nine months ended September 30, 2016 and 2015 , as reported to the Company by kaléo, are provided below: (In Thousands) September 30, 2016 December 31, 2015 September 30, 2016 December 31, 2015 Assets: Liabilities & Equity: Cash & short-term investments $ 111,305 $ 91,844 Restricted cash 30 8,182 Other current assets 16,361 9,070 Current liabilities $ 54,434 $ 10,261 Property & equipment 14,072 8,453 Long term debt, net 143,212 142,696 Patents 2,865 2,811 Other noncurrent liabilities 767 552 Other long-term assets 93 92 Equity (53,687 ) (33,057 ) Total assets $ 144,726 $ 120,452 Total liabilities & equity $ 144,726 $ 120,452 Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Revenues & Expenses: Revenues, net $ 17,377 $ 28,084 $ 29,347 $ 43,002 Cost of goods sold (2,956 ) (3,438 ) (10,564 ) (8,575 ) Expenses and other, net (a) (22,216 ) (17,337 ) (39,815 ) (45,727 ) Income tax benefit (expense) — — (8 ) (4 ) Net income (loss) $ (7,795 ) $ 7,309 $ (21,040 ) $ (11,304 ) (a) “Expenses and other, net” includes selling, general and administrative expense, research and development expense, gain on contract termination, interest expense and other income (expense), net. Excluding the gain on contract termination, “Expenses and other, net” would have been a net deduction of $22.2 million and $57.9 million in the third quarter and first nine months of 2016, respectively. The Company’s investment in the Harbinger Capital Partners Special Situations Fund, L.P. (“Harbinger Fund”) had a carrying value (included in “Other assets and deferred charges”) of $1.7 million at September 30, 2016 and December 31, 2015 . The carrying value at September 30, 2016 reflected Tredegar’s cost basis in its investment in the Harbinger Fund, net of total withdrawal proceeds received and unrealized losses. Withdrawal proceeds received were $0.1 million in the first nine months of 2015 (none in 2016). The timing and amount of future installments of withdrawal proceeds, which commenced in August 2010, were not known as of September 30, 2016 . Gains on the Company’s investment in the Harbinger Fund will be recognized when the amounts expected to be collected from any withdrawal from the investment are known, which will likely be when cash in excess of the remaining carrying value is received. Losses will be recognized when management believes it is probable that future withdrawal proceeds will not exceed the remaining carrying value.

Derivative Financial Instrument

Derivative Financial Instruments	Sep. 30, 2016
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 currency exchange rate exposures that exist as part of ongoing PE Films and Flexible Packaging Films business operations. 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 are based upon Level 2 inputs. 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, and the notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $10.5 million ( 12.9 million pounds of aluminum) at September 30, 2016 and $16.6 million ( 18.9 million pounds of aluminum) at December 31, 2015 . The table below summarizes the location and gross amounts of aluminum futures contract fair values in the consolidated balance sheets as of September 30, 2016 and December 31, 2015 : September 30, 2016 December 31, 2015 (In Thousands) Balance Sheet Account Fair Value Balance Sheet Account Fair Value Derivatives Designated as Hedging Instruments Asset derivatives: Accrued expenses $ 59 Accrued expenses $ 44 Liability derivatives: Accrued expenses $ (236 ) Accrued expenses $ (1,797 ) Derivatives Not Designated as Hedging Instruments Asset derivatives: Accrued expenses $ — Accrued expenses $ — Liability derivatives: Accrued expenses $ — Accrued expenses $ — Net asset (liability) $ (177 ) $ (1,753 ) 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. 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 our foreign currency futures and zero-cost collar contracts are major financial institutions. The 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 and nine month periods ended September 30, 2016 and 2015 is summarized in the table below: (In Thousands) Cash Flow Derivative Hedges Aluminum Futures Contracts Foreign Currency Forwards Three Months Ended September 30, 2016 2015 2016 2015 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (230 ) $ (1,570 ) $ — $ — Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (loss) (effective portion) Cost of Cost of Cost of Cost of Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (loss) (effective portion) $ (160 ) $ (1,338 ) $ 15 $ 15 Aluminum Futures Contracts Foreign Currency Forwards Nine Months Ended September 30, 2016 2015 2016 2015 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (93 ) $ (4,699 ) $ — $ — Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (loss) (effective portion) Cost of Cost of Cost of Cost of Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (loss) (effective portion) $ (1,669 ) $ (1,867 ) $ 46 $ 46 As of September 30, 2016 , the Company expects $0.1 million of unrealized after-tax losses on derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months. For the three and nine month periods ended September 30, 2016 and 2015 , net gains or losses realized, from previously unrealized net gains or losses on hedges that had been discontinued, were not material.

Compensation and Retirement Disclosure [Abstract]
Pension And Other Post-Retirement Benefits	The Company sponsors noncontributory defined benefit (pension) plans covering most employees. The plans for salaried and hourly employees currently in effect are based on a formula using the participant’s years of service and compensation or using the participant’s years of service and a dollar amount. The plan was closed to new participants in 2006 and pay for active plan participants was frozen as of December 31, 2007. With the exception of plan participants at one of Tredegar’s U.S. manufacturing facilities, the plan no longer accrues benefits associated with crediting employees for service, thereby freezing future benefits under the plan. The components of net periodic benefit cost for the pension and other post-retirement benefit programs reflected in consolidated results are shown below: Pension Benefits Other Post-Retirement Benefits Three Months Ended September 30, Three Months Ended September 30, (In Thousands) 2016 2015 2016 2015 Service cost $ 54 $ 110 $ 8 $ 9 Interest cost 3,263 3,288 67 77 Expected return on plan assets (4,070 ) (4,413 ) — — Amortization of prior service costs, gains or losses and net transition asset 3,135 4,094 (49 ) (65 ) Net periodic benefit cost $ 2,382 $ 3,079 $ 26 $ 21 Pension Benefits Other Post-Retirement Benefits Nine Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Service cost $ 178 $ 398 $ 29 $ 33 Interest cost 9,993 9,913 236 244 Expected return on plan assets (12,027 ) (13,227 ) — — Amortization of prior service costs, (gains) losses and net transition asset 9,903 12,142 (144 ) (145 ) Net periodic benefit cost $ 8,047 $ 9,226 $ 121 $ 132 Pension and other post-retirement liabilities were $92.2 million and $101.0 million at September 30, 2016 and December 31, 2015 , respectively ( $0.6 million included in “Accrued expenses” at September 30, 2016 and December 31, 2015 , with the remainder included in “Other noncurrent liabilities” in the consolidated balance sheets). The Company’s required contributions are expected to be approximately $8 million in 2016 . Contributions to the pension plan during the first nine months of 2016 were $6.9 million . Tredegar funds its other post-retirement benefits (life insurance and health benefits) on a claims-made basis, which the Company anticipates will be consistent with amounts paid for the year ended December 31, 2015 , or $0.3 million .

Income Tax Disclosure [Abstract]
Income Taxes	the U.S. federal statutory rate and the effective income tax rate for the nine months ended September 30, 2016 and 2015 are as follows: Percent of Income Before Income Taxes Nine Months Ended September 30, 2016 2015 Income tax expense at federal statutory rate 35.0 35.0 Non-deductible expenses 1.6 (1.7 ) Income tax contingency accruals and tax settlements 1.3 (2.8 ) Foreign rate differences 1.1 2.8 State taxes, net of federal income tax benefit 0.7 (2.4 ) Valuation allowance for foreign operating loss carry-forwards 0.3 (1.0 ) Foreign investment write-up 0.1 — Valuation allowance for capital loss carry-forwards (0.4 ) 1.8 Unremitted earnings from foreign operations (1.1 ) (2.0 ) Changes in estimates related to prior year tax provision (1.6 ) 2.9 Research and development tax credit (1.8 ) — Domestic production activities deduction (3.8 ) 5.1 Remitted earnings from foreign operations (23.8 ) — Goodwill impairment charge — (90.5 ) Other — 0.1 Effective income tax rate 7.6 (52.7 ) Tredegar accrues U.S. federal income taxes on unremitted earnings of all foreign subsidiaries. Prior to the second quarter of 2016, deferred U.S. federal income taxes had not been recorded for the undistributed earnings for Terphane Ltda. because the Company had intended to permanently reinvest these earnings. Due to concerns about the current political and economic conditions in Brazil, Terphane Ltda. has begun making cash distributions to the Company. During the second quarter of 2016, Terphane Ltda. paid a dividend of $10.7 million to the Company. The 2016 low effective tax rate is due to the $5.7 million tax benefit from excess foreign tax credits that are related to the repatriation of cash from Brazil. The recognition in the third quarter of 2016, instead of the second quarter of 2016, is due to an accounting method change that was filed along with the Federal income tax return in the third quarter. Because of the accumulation of significant losses related to foreign currency translations at Terphane Ltda., there were no unrecorded deferred tax liabilities associated with the U.S. federal income taxes and foreign withholding taxes on Terphane Ltda.’s undistributed earnings as of September 30, 2016 and December 31, 2015 . 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 Holdings LLC’s (“Terphane”) 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 10 -year period, which has a retroactive commencement date of January 1, 2015. No benefit was recognized from these tax incentives in the first nine months of 2016 or 2015 . In connection with its capacity expansion project in Brazil, the Company paid certain social taxes associated with the purchase of machinery and equipment and construction of buildings and other long-term assets. Payments of these taxes in Brazil were included in “Net cash used in investing activities” given the nature of the underlying use of cash (e.g. the purchase of property, plant and equipment). The Company can recover tax credits associated with the purchase of machinery and equipment at different points over a period up to 24 months. Once the machinery and equipment was placed into service in the fourth quarter of 2014, the Company started applying these tax credits against various other taxes due in Brazil, with their recovery being reflected as cash received from investing activities, consistent with the classification of the original payments. Income taxes in 2016 included a partial reversal of a valuation allowance of $0.1 million related to the expected limitations on the utilization of assumed capital losses on certain investments that were recognized in prior years. Income taxes in 2015 included the partial reversal of a valuation allowance of $0.3 million related to the expected limitations on the utilization of assumed capital losses on certain investments. The Company had a valuation allowance for excess capital losses from investments and other related items of $10.8 million at September 30, 2016 . Tredegar continues to evaluate opportunities to utilize these loss carryforwards prior to their expiration at various dates in the future. As events and circumstances warrant, allowances will be reversed when it is more likely than not that future taxable income will exceed deductible amounts, thereby resulting in the realization of deferred tax assets. Tredegar and its subsidiaries file income tax returns in the U.S., various states and jurisdictions outside the U.S. With few exceptions, 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 2013.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	On March 1, 2016, Tredegar entered into a $400 million five -year, secured revolving credit facility (“Credit Agreement”), with an option to increase that amount by $50 million . The Credit Agreement replaced the Company’s previous $350 million five-year, unsecured revolving credit facility that was due to expire on April 17, 2017. In connection with the refinancing, the Company borrowed $107 million under the Credit Agreement, which was used, together with available cash on hand, to repay all indebtedness under the previous revolving credit facility. Borrowings under the Credit Agreement bear an interest rate of LIBOR plus a credit spread and commitment fees charged on the unused amount under the Credit Agreement at various indebtedness-to-adjusted EBITDA levels as follows: Pricing Under Credit Revolving Agreement (Basis Points) Indebtedness-to-Adjusted EBITDA Ratio Credit Spread Over LIBOR Commitment Fee > 3.5x but <= 4.0x 250 45 > 3.0x but <= 3.5x 225 40 > 2.0x but <= 3.0x 200 35 > 1.0x but <= 2.0x 175 30 <= 1.0x 150 25 At September 30, 2016 , the interest cost on debt borrowed under the Credit Agreement was priced at one-month LIBOR plus the applicable credit spread of 175 basis points.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	In 2011, Tredegar was notified by U.S. Customs and Border Protection (“U.S. Customs”) that certain film products exported by Terphane to the U.S. since November 6, 2008 could be subject to duties associated with an antidumping duty order on imported PET films from Brazil. The Company contested the applicability of these antidumping duties to the films exported by Terphane, and it filed a request with the U.S. Department of Commerce (“Commerce”) for clarification about whether the film products at issue are within the scope of the antidumping duty order. On January 8, 2013, Commerce issued a scope ruling confirming that the films are not subject to the order, provided that Terphane can establish to the satisfaction of U.S. Customs that the performance enhancing layer on those films is greater than 0.00001 inches thick. The films at issue are manufactured to specifications that exceed that threshold. On February 6, 2013, certain U.S. producers of PET film filed a summons with the U.S. Court of International Trade to appeal the scope ruling from Commerce. If U.S. Customs ultimately were to require the collection of anti-dumping duties because Commerce’s scope ruling was overturned on appeal, or otherwise, indemnifications for related liabilities are specifically provided for under the purchase agreement pursuant to which the Company acquired Terphane. In December 2014, the U.S. International Trade Commission voted to revoke the anti-dumping duty order on imported PET films from Brazil. The revocation, as a result of the vote by the U.S. International Trade Commission, was effective as of November 2013. On February 20, 2015, certain U.S. producers of PET films filed a summons with the U.S. Court of International Trade to appeal the determination by the U.S. International Trade Commission. The Court granted a motion by the plaintiffs to stay the appeal of the revocation decision pending the resolution of the scope appeal. A decision by the Court in the scope appeal remains pending.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board (“IASB”) issued their converged standard on revenue recognition. The revised revenue standard contains principles that an entity will apply to direct the measurement of revenue and timing of when it is recognized. The core principle of the guidance is that the recognition of revenue should depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods and services. To achieve that core principle, an entity will utilize a principle-based five-step approach model. The converged standard also includes more robust disclosure requirements which will require entities to provide sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In March 2016, amended guidance was issued regarding clarifying the implementation guidance on principal versus agent considerations and in April 2016, clarifying guidance was issued relating to identifying performance obligations and licensing implementation. The effective date of this revised standard is for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The converged standard can be adopted either retrospectively or through the use of a practical expedient. The Company is currently assessing the impact of this standard. In July 2015, the FASB issued new guidance for the measurement of inventories. Inventories within the scope of the revised guidance should be measured at the lower of cost or net realizable value. The previous guidance dictated that inventory should be measured at the lower of cost or market, with market being either replacement cost, net realizable value or net realizable value less an approximation of normal profit margin. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventories measured using LIFO or the retail inventory method. The new guidance is effective for fiscal years beginning after December 31, 2016, including the interim periods within those fiscal years. The amendments should be applied prospectively, with early adoption permitted. The Company is not expecting to be materially impacted by this amended guidance. In January 2016, the FASB issued amended guidance associated with accounting for equity investments measured at fair value. The amended guidance requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amended guidance also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The amended guidance is effective for fiscal years beginning after December 31, 2017, including the interim periods within those fiscal years. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the update. Early adoption is permitted under limited, specific circumstances. The Company is still assessing the impact of this amended guidance. In February 2016, the FASB issued a revised standard on lease accounting. Lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The revised standard requires additional analysis of the components of a transaction to determine if a right-to-use asset is embedded in the transaction that needs to be treated as a lease. Substantial additional disclosures are also required by the revised standard. The revised standard is effective for fiscal years beginning after December 31, 2018, including the interim periods within those fiscal years. The revised standard should be applied on a modified retrospective approach or through the use of a practical expedient, with early adoption permitted. The Company is still assessing the impact of this revised standard. In March 2016, the FASB issued amended guidance to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The updated guidance is effective for fiscal years beginning after December 31, 2016, including the interim periods within those fiscal years. The updated standard can be applied on a retrospective or modified retrospective basis, with early adoption permitted. The Company is not expecting to be materially impacted by this amended guidance. In June 2016, the FASB issued new accounting guidance that will require the earlier recognition of credit losses on loans and other financial instruments based on an expected loss model, replacing the incurred loss model that is currently in use. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The expected loss model will apply to loans and leases, unfunded lending commitments, held-to-maturity (HTM) debt securities and other debt instruments measured at amortized cost and accounts receivable. The new guidance is effective for fiscal years beginning after December 31, 2019, including the interim periods within those fiscal years, with early adoption allowed for fiscal years beginning after December 31, 2018. The new guidance must be applied on a modified retrospective basis, with a cumulative effect adjustment recorded to opening retained earnings. The Company is not expecting to be materially impacted by this new guidance.
