	In the opinion of management, the accompanying 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 September 30, 2014, the consolidated results of operations for the three and nine months ended September 30, 2014 and 2013, the consolidated cash flows for the nine months ended September 30, 2014 and 2013, and the consolidated changes in shareholders’ equity for the nine months ended September 30, 2014. All such adjustments, unless otherwise detailed in the notes to the consolidated interim financial statements, are deemed to be of a normal, recurring nature. The financial position data as of December 31, 2013 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, 2013 (“2013 Form 10-K”) but does not include all disclosures required by United States generally accepted accounting principles (“U.S. GAAP”).

Acquisitions	'
	On October 1, 2012, The William L. Bonnell Company, Inc. acquired 100% ownership of AACOA, Inc. (“AACOA”). AACOA operates production facilities in Elkhart, Indiana and Niles, Michigan. Its primary markets include consumer durables, machinery and equipment and transportation. The acquisition added fabrication capabilities to Aluminum Extrusions’ current array of products and services, and provided AACOA with large press capabilities and enhanced geographic sales coverage in a variety of end-use markets.
	In the second quarter of 2013, all post-closing adjustments to the purchase price were resolved. Adjustments to the purchase price were made retrospectively as if the accounting had been completed on the acquisition date. Upon completing these post-closing adjustments, which were primarily related to the resolution of contractual obligations related to income taxes, the total purchase price (net of cash acquired) was $54.1 million, which includes $0.6 million that was received from the seller during the third quarter of 2013. The purchase price was funded using financing secured from the Company’s existing $350 million revolving credit facility. Based upon management’s valuation of the fair value of tangible and intangible assets (net of cash) acquired and liabilities assumed, the purchase price allocation was as follows:
	(In Thousands)
	Accounts receivable		$	12,477
	Inventories		4,708
	Property, plant & equipment		15,116
	Identifiable intangible assets:
	Customer relationships		4,800
	Trade names		4,800
	Proprietary technology		3,400
	Noncompete agreements		1,600
	Other assets (current & noncurrent)		42
	Trade payables & accrued expenses		(6,574		)
	Total identifiable net assets		40,369
	Purchase price, net of cash received		54,065
	Goodwill		$	13,696
	The goodwill and other intangible asset balances associated with this acquisition are expected to be deductible for tax purposes. Intangible assets acquired in the purchase of AACOA are being amortized over the following periods:
	Identifiable Intangible Asset	Useful Life (Yrs)
	Customer relationships	10
	Proprietary technology	10-Jun
	Trade names	Indefinite

Discontinued Operations	'
	On February 12, 2008, Tredegar sold its aluminum extrusions business in Canada for approximately $25.0 million to an affiliate of H.I.G. Capital. All historical results for this business have been reflected as discontinued operations; however, cash flows for discontinued operations have not been separately disclosed in the consolidated statements of cash flows. Accruals for indemnifications under the purchase agreement related to environmental matters were adjusted in the third quarter and first nine months of 2014, resulting in income from discontinued operations of $0.9 million ($0.9 million after taxes) for both periods. Accruals of $0.5 million ($0.5 million after taxes) and $14.0 million ($14.0 million after taxes) were made for indemnifications under the purchase agreement related to environmental matters in the third quarter and the first nine months of 2013, respectively.

Earnings Per Share	'
	Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net income by the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows:
		Three Months Ended		Nine Months Ended
		September 30,		September 30,
	(In Thousands)	2014	2013	2014	2013
	Weighted average shares outstanding used to compute basic earnings per share	32,319	32,201	32,291	32,155
	Incremental dilutive shares attributable to stock options and restricted stock	188	457	298	436
	Shares used to compute diluted earnings per share	32,507	32,658	32,589	32,591
	Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. For the three and nine months ended September 30, 2014, average out-of-the-money options to purchase shares were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 343,656 and 228,533, respectively. For the three and nine months ended September 30, 2013, average out-of-the-money options to purchase shares were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 60,100 and 40,056, respectively.

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. The mission of kaléo is to set a new standard in life-saving personal medical products designed to enable superior treatment outcomes, improved cost effectiveness and intuitive patient administration. Tredegar’s ownership interest on a fully diluted basis is approximately 20%, 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.
	At September 30, 2014 and December 31, 2013, 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 sheet) was $40.0 million and $37.1 million, respectively. The fair value estimates are based upon significant unobservable (Level 3) inputs since there is no secondary market for our ownership interest. Accordingly, until the next round of financing or other significant financial transaction, value estimates will primarily be based on assumptions relating to meeting product development and commercialization milestones, corresponding cash flow projections (projections of sales, costs, expenses, capital expenditures and working capital investment) and discounting of these factors for the high degree of risk. Adjustments to the estimated fair value of the Company’s investment in kaléo will be made in the period during which changes can be quantified.
	The Company recognized unrealized gains on its investment in kaléo (included in “Other income (expense), net” in the consolidated statements of income) of $4.0 million in the third quarter of 2014 and $2.9 million in first nine months of 2014. The unrealized gain in the third quarter of 2014 can be primarily attributed to favorable adjustments for the passage of time as cash flows associated with achieving product development and commercialization milestones are discounted at 45% for their high degree of risk. In addition to the passage of time for discounted cash flows, the year-to-date change in the fair value of kaléo reflected the impact of a lower weighted average cost of capital used to discount cash flow projections and adjustments to the amount and timing of cash flows associated with achieving product development and commercialization milestones. The Company recognized an unrealized loss on its investment in kaléo (included in “Other income (expense), net” in the consolidated statements of income) of $3.1 million in the third quarter of 2013 and and unrealized gain of $0.1 million in the first nine months of 2013. The unrealized loss in the third quarter of 2013 was primarily related to adjustments in the fair value due to a reassessment of the amount and timing of the projected receipt of royalty and milestone payments from commercial sales of kaléo’s licensed epinephrine auto-injector, which launched in early 2013, and increased development and commercialization expenses related to its pipeline products, partially offset by the impact of the passage of time as anticipated cash flows associated with achieving product development and commercialization milestones were discounted at 55% for their high degree of risk. The net unrealized gain in the first nine months of 2013 was primarily related to adjustments in the fair value for the passage of time as anticipated cash flows associated with achieving product development and commercialization milestones were discounted at 55% for their high degree of risk, offset by adjustments in the fair value due to a reassessment of the amount and timing of projected royalty and milestone payments from commercial sales of kaléo’s licensed epinephrine auto-injector and increased commercialization expenses related to its pipeline products.
	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 September 30, 2014 and 55% at December 31, 2013. In 2014, the weighted average cost of capital used to discount cash flow projections was decreased to reflect lower product risk after the U.S. Food and Drug Administration’s approval of kaléo’s naloxone auto-injector for emergency treatment of known or suspected opioid overdoses and reduced funding risk subsequent to kaléo securing new debt financing, both of which occurred in April 2014. At September 30, 2014, the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have further increased the fair value of the interest in kaléo by approximately $8 million, and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of the interest by approximately $6 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, 2014 and December 31, 2013 and condensed statement of operations for the three and nine months ended September 30, 2014 and 2013, as reported to the Company by kaléo, are provided below:

	The Company’s investment in the Harbinger Fund had a carrying value (included in “Other assets and deferred charges”) of $1.8 million at September 30, 2014, compared with $2.8 million at December 31, 2013. The carrying value at September 30, 2014 reflected Tredegar’s cost basis in its investment in the Harbinger Fund, net of total withdrawal proceeds received and unrealized losses. The Company recorded unrealized losses of $0.2 million and $0.8 million in the third quarter and first nine months of 2014, respectively, on its investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income) as a result of a reduction in the value of the investment that is not expected to be temporary. The Company recorded an unrealized loss of $0.2 million in the third quarter and first nine months of 2013, respectively, on its investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income) as a result of a reduction in the value of the investment that is not expected to be temporary. Withdrawal proceeds were $0.2 million in the first nine months of 2014 and 2013, respectively. The timing and amount of future installments of withdrawal proceeds, which commenced in August 2010, were not known as of September 30, 2014. 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.
	Tredegar has investment property in Alleghany and Bath Counties, Virginia. The Company realized a gain (included in “Other income (expense), net” in the consolidated statements of income) of $1.2 million ($0.8 million after taxes) on the sale of a portion of this investment property in the second quarter of 2014. An unrealized loss associated with the Company’s investment property in Alleghany and Bath Counties, Virginia (included in “Other income (expense), net” in the consolidated statements of income) of $1.0 million ($0.6 million after taxes) was recorded in the second quarter of 2013 as a result of a reduction in the estimated fair value of our investment that is not expected to be temporary. The carrying value in this investment property (included in “Other assets and deferred charges” on the consolidated balance sheets) was $2.6 million at September 30, 2014 and $5.9 million at December 31, 2013.

Summary of Derivative Instruments [Abstract]	'
Derivative Financial Instruments	'
	The Company 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 due to specified transactions. When possible, derivative financial instruments utilized by Tredegar are designated as and qualify as cash flow hedges and are recognized in the balance sheet at fair value. A change in the fair value of derivatives that are highly effective and that are designated and qualify as cash flow hedges is recorded in other comprehensive income (loss). Gains and losses reported in other comprehensive income (loss) are reclassified to earnings in the periods in which earnings are affected by the variability of cash flows of the hedged transaction. Such gains and losses are reported on the same line as the underlying hedged item. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current period earnings. The amount of gains and losses recognized for hedge ineffectiveness was not material to the three and nine month periods ended September 30, 2014 and 2013.
	The fair value of derivative instruments recorded on the consolidated balance sheets are based upon Level 2 inputs within the corresponding commodity or foreign currency markets. 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, the Company 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 the margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, the Company 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 $4.9 million (4.7 million pounds of aluminum) at September 30, 2014 and $8.0 million (8.4 million pounds of aluminum) at December 31, 2013.
	The table below summarizes the location and gross amounts of aluminum futures contract fair values in the consolidated balance sheets as of September 30, 2014 and December 31, 2013:
		30-Sep-14						31-Dec-13
	(In Thousands)	Balance Sheet		Fair				Balance Sheet	Fair

	Aluminum futures contracts	and other
	Net asset (liability)			$	324				$	(147	)
	In the event that the counterparty to an aluminum fixed-price forward sales contract chooses to not take delivery of its aluminum extrusions, the customer is contractually obligated to compensate us for any losses on the related aluminum futures and/or forward purchase contracts through the date of cancellation. The offsetting asset and liability positions for derivatives not designated as hedging instruments (none at September 30, 2014 and December 31, 2013) are associated with the unwinding of aluminum futures contracts that relate to such cancellations.
	Film Products utilized future fixed Euro-denominated contractual payments for equipment being purchased as part of our multi-year capacity expansion project at our film products manufacturing facility in Cabo de Santo Agostinho, Brazil. The Company is using fixed-rate Euro forward contracts with various settlement dates through December 2014 to hedge exchange rate exposure on these obligations. The Company had fixed-rate forward contracts with outstanding notional amounts of €2.0 million and €2.1 million as of September 30, 2014 and December 31, 2013, respectively.
	The table below summarizes the location and gross amounts of foreign currency forward contract fair values in the consolidated balance sheets as of September 30, 2014 and December 31, 2013:
		30-Sep-14						31-Dec-13

	Liability derivatives:	Accrued expenses		$	(112	)			$	—
	Foreign currency forward contracts
	Net asset (liability)			$	(112	)			$	47
	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 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, 2014 and 2013 is summarized in the table below:
	(In Thousands)	Cash Flow Derivative Hedges

For the three and nine month periods ended September 30, 2014 and 2013, net gains or losses realized on previously unrealized net gains or losses from hedges that had been discontinued were not significant.

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 is closed to new participants, and based on plan changes announced in 2006, pay for active plan participants was frozen as of December 31, 2007. Beginning in the first quarter of 2014, with the exception of plan participants at two of Tredegar’s U.S. manufacturing facilities, the plan will no longer accrue benefits associated with crediting employees for service, thereby freezing future benefits under the plan.
	The components of net periodic benefit cost for our pension and other post-retirement benefit programs reflected in consolidated results are shown below:

The Company’s required contributions are expected to be approximately $0.2 million in 2014. The Company made an additional discretionary contribution of $2.6 million to its underfunded pension plan in September 2014. 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, 2013, or $0.3 million .

	The effective tax rate for income from continuing operations in the first nine months of 2014 was 34.6% compared to 31.5% in the first nine months of 2013. The significant differences between the U.S. federal statutory rate and the effective income tax rate for continuing operations for the nine months ended September 30, 2014 and 2013 are as follows:
		Percent of Income

	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 levied on the operating profit of its products. These incentives produce a current effective tax rate of 15.25% for Terphane Ltda. (6.25% of income tax and 9.0% social contribution on income). The current incentives will expire at the end of 2014, but the Company anticipates that it will qualify for additional incentives that will extend beyond 2014. The benefit from tax incentives was $42,000 (0 cents per share) and $1.9 million (6 cents per share) in the first nine months of 2014 and 2013, respectively.
	In connection with its capacity expansion project in Brazil, the Company has 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 have been 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 period up to 24 months. Tax credits will be applied 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 payment.
	The Company has a valuation allowance for excess capital losses from investments and other related items of $16 million at September 30, 2014. 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 state or non-U.S. income tax examinations by tax authorities for years before 2010.

Shareholder Rights Agreement	'
	Pursuant to the Second Amended and Restated Rights Agreement (the “Rights Agreement”), dated as of November 18, 2013, with Computershare Trust Company, N.A., as Rights Agent, one purchase right (a “Right”) was attached to each outstanding share of the Company’s Common Stock.  All Rights previously issued under the original Rights Agreement, dated as of June 30, 1999, and the Amended and Restated Rights Agreement, dated as of June 30, 2009, that were appurtenant to shares of Common Stock outstanding at the effective time of the Rights Agreement remained outstanding.
	Each Right entitled the registered holder to purchase from Tredegar one one-hundredth of a share of our Series A Participating Cumulative Preferred Stock (the “Preferred Stock”) at an exercise price of $150, subject to adjustment (the “Purchase Price”). The Rights will become exercisable, if not earlier redeemed, only if a person or group (i) acquires beneficial ownership of 20% or more of the outstanding shares of our Common Stock or (ii) commences, or publicly discloses an intention to commence, a tender offer or exchange offer that would result in beneficial ownership by a person or group of 20% or more of the outstanding shares of our Common Stock (in each case thereby becoming an “Acquiring Person”).  Any person or group that beneficially owned 20% or more of the outstanding shares of the Company’s Common Stock as of the first date of public announcement of the adoption of the Rights Agreement will not become an Acquiring Person unless and until such person or group acquires beneficial ownership of additional shares of Common Stock (other than beneficial ownership of any Common Stock which is acquired, whether in the form of options, restricted stock or other equity-linked securities, as compensation for services as an officer or director of the Company) representing 1% or more of the Common Stock then outstanding.
	The Rights Agreement provided that if any person or group becomes an Acquiring Person, each holder of a Right (other than Rights held by an Acquiring Person) will become entitled to receive, upon exercise and payment of the Purchase Price, Preferred Stock or, at the option of Tredegar, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to twice the amount of the Purchase Price.  In addition, in the event that, at any time following the date that a person or group acquires beneficial ownership of 20% or more of the outstanding shares of the Company’s Common Stock,  (i) Tredegar is acquired in a merger, statutory share exchange, or other business combination in which Tredegar is not the surviving corporation, or (ii) 50% or more of our assets or earning power is sold or transferred, each holder of a Right (other than Rights held by an Acquiring Person) shall thereafter have the right to receive, upon exercise and payment of the Purchase Price, common stock of the acquiring company (or comparable equity securities of an acquiring entity that is not a corporation) having a value equal to twice the Purchase Price.
	The Rights were scheduled to expire on June 30, 2019.  On February 19, 2014, the Company’s Board of Directors authorized the termination of the Rights Agreement and the redemption of all of the outstanding Rights, at a redemption price of $.01 per Right to be paid in cash to shareholders of record as of the close of business on March 3, 2014. The corresponding redemption payment of $0.3 million was made in the first quarter of 2014.

Contingencies	'
	In 2011, Tredegar was notified by U.S. Customs and Border Protection (“U.S. Customs”) that certain film products exported by Terphane Holdings, LLC (“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 antidumping duties because Commerce’s scope ruling was overturned on appeal, or otherwise, indemnifications for related liabilities are specifically provided for under the Terphane purchase agreement.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
New Accounting Pronouncements	'
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued a revised standard that changes current guidance for discontinued operations. Under the revised standard, to be a discontinued operation, a component or group of components must represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Failure to eliminate significant continuing cash flows of or involvement with a disposed component from an entity’s ongoing operations after a disposal no longer precludes presentation as a discontinued operation. Expanded disclosures for discontinued operations under the revised standard will also include more details about earnings and balance sheet accounts, total operating and investing cash flows and cash flows resulting from continuing involvement. New disclosures are also required for disposals of individually significant components that do not qualify as discontinued operations. The new guidance is to be applied prospectively to all new disposals of components and new classifications as held for sale for annual reporting periods beginning after December 15, 2014, with early adoption permitted. The Company will implement this revised standard as transactions and events warrant.
	In May 2014, the 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. The amendments in this revised standard are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The converged standard can be adopted either retrospectively or through the use of a practical expedient. The Company is still assessing the impact of this new guidance.
	In June 2014, the FASB issued a new standard to eliminate the concept of development stage entities and all specified presentation and reporting requirement under U.S. GAAP. In addition, the amended standard eliminated the scope exception for development stage entities when evaluating the sufficiency of equity at risk for a variable interest entity (“VIE”), thereby changing consolidation conclusions in some situations. Except for the elimination of the scope exception for development stage entities when evaluating the sufficiency of equity at risk for a VIE, the revised guidance is effective for annual reporting periods beginning after December 15, 2014, including interim periods within that reporting period. The amendments to the consolidation guidance are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The new standard is not expected to impact the Company.
	In June 2014, the FASB amended the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating grant-date value of the award, and compensation expense should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The amended standard is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted. The new standard is not expected to impact the Company.
