SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	A. Nature of Business and Consolidation Policy: We are a global specialty materials and chemicals company focused on developing, manufacturing and selling value-added products. Our products serve a diverse range of end markets including aerospace and industrial materials, mining and plastics. We use our technology and application development expertise to create chemical and material solutions that are formulated to perform specific and important functions for our customers. We operate on a global basis with 48% of our 2014 revenues in North America, 31% in Europe, Middle East, and Africa, 12% in Asia-Pacific, and 9% in Latin America. We have manufacturing and research facilities located in 11 countries. The consolidated financial statements include the accounts of Cytec Industries Inc. and our subsidiaries on a consolidated basis. The footnotes relate to continuing operations except where noted otherwise. Intercompany transactions and balances have been eliminated. The equity method of accounting is used for investments in associated companies that we do not control, but for which we have the ability to exercise significant influence on operating and financial policy.
	B. Inventories: Inventories are stated at the lower of cost or market. We determine cost using the first-in, first-out method.
	C. Currency Translation: Operations in our international subsidiaries are recorded in local currencies, which are also the functional currencies for financial reporting purposes. The results of operations for our international subsidiaries are translated from local currencies into U.S. dollars (“USD”) using the average currency rate during each period which approximates the results that would be obtained using actual currency rates on the dates of individual transactions. Assets and liabilities are translated using currency rates at the end of the period with translation adjustments recorded in accumulated translation adjustments and recognized as a component of accumulated other comprehensive income (“OCI”). Gains and losses on foreign currency transactions, which represent the translation of transactions denominated in currencies other than the functional currency of the impacted legal entity, are recorded as incurred in Other (expense) income, net.
	D. Depreciation: Depreciation is provided on a straight-line basis over the estimated useful lives of the assets. When these assets are retired or disposed of, the net book value of assets are removed from the consolidated balance sheet and the net gain or loss is included in the determination of earnings from operations.
	Expenditures for maintenance and repairs are charged to current operating expenses. Acquisitions, additions, and betterments, either to provide necessary capacity, improve the efficiency of production units, modernize or replace older facilities, or to install equipment for protection of the environment, are capitalized. We capitalize interest costs incurred during the period of construction of plants and equipment.
	E. Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of: Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets and would be charged to income. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the costs to sell.
	F. Goodwill and Intangible Assets: We have defined our reportable segments as our reporting units for our goodwill accounting. We test goodwill for impairment on an annual basis as of October 1st and more often if events occur or circumstances change that would likely reduce the fair value of a reporting unit to an amount below its carrying value. When necessary, we record charges for goodwill impairments for the amount by which the implied fair value of goodwill is less than its carrying value.
	We test our goodwill using either a qualitative or quantitative approach. Under the qualitative approach for a goodwill impairment test, we first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (i.e. – greater than 50% probability) that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of the facts and circumstances, we determine it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then performing the two-step impairment test, described below, is unnecessary. If we determined otherwise, we would be required to perform the two-step goodwill impairment test. For our qualitative assessment of the reporting unit, we consider all relevant facts and circumstances, including the excess fair value from the most recent fair value calculation; circumstances that could cause significant changes to the most recent carrying value calculation; the overall financial performance of the reporting unit compared to previous projections; the estimated financial performance projected in the near and long term, such as Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and cash flows; industry and market conditions, including overall market-multiple metrics, competitive environment and demand for our products; overall macroeconomic conditions including our ability to access capital; and changes in management, key personnel or strategy for the reporting unit. More weight is placed on events or circumstances that most affect a reporting unit’s fair value or carrying amount of its net assets.
	If we decide to or are required to perform the two-step goodwill impairment test, we begin by comparing the reporting unit’s fair value to its carrying value. We initially use a market multiple approach (1A) to estimate a range of fair values by reporting unit, and then use a discounted cash flow approach (1B) if the market multiple approach indicates that a potential impairment might exist to refine and reaffirm the results of the first test. Due to the cyclical nature of our reporting units, market multiple values are determined utilizing a three-year average of EBITDA. The three-year period is comprised of the prior year, current year, and one year of projected amounts. If the reporting unit’s estimated fair value at the low end of the range is close to, in our judgment, or below the reporting unit’s carrying value, we refine the calculation using discounted cash flows to calculate a point estimate of the reporting unit’s fair value, as opposed to a range. If the discounted cash flow approach yields a fair value estimate less than the reporting unit’s carrying value, we would proceed to step two of the impairment test, which is used to measure the amount of the impairment loss. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The resulting implied fair value of the goodwill that results from the application of this second step would then be compared to the carrying amount of the goodwill and an impairment charge would be recorded for the difference.
	Intangible assets are amortized on a straight-line basis over their respective estimated useful lives. Intangible assets with determinable useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets and would be charged to income.
	G. Cash and Cash Equivalents: Securities with maturities of three months or less when purchased are considered to be cash equivalents.
	H. Financial Instruments: Certain financial instruments are recorded at cost, which approximates fair value such as cash and cash equivalents, receivables, certain other assets, accounts payable, and certain other liabilities. Fair values are determined through a combination of management estimates and information obtained from third parties using the latest available market data. Long-term debt is carried at amortized cost.
	I. Derivative Instruments and Hedging Activities: We use derivative instruments in accordance with our established policies to manage exposure to fluctuations in currency rates, interest rates, and, at times, certain commodity costs. We do not hold or issue derivative financial instruments for trading or speculative purposes. We enter into financial instrument transactions with either major financial institutions or highly rated counterparties and make reasonable attempts to diversify transactions among counterparties, thereby limiting exposure to credit-related and performance-related risks.
	Foreign Currency Risk: We use currency forward contracts and have used cross currency swaps to manage our exposure to fluctuations in currency rates on third party and intercompany transactions denominated in currencies other than the functional currency of the legal entity. We hedge such exposures with currency forward contracts denominated in the same currency and with similar terms as the underlying exposure, and therefore, the instruments are effective at generating offsetting changes in the fair value or cash flows of the hedged item or transaction. All derivative contracts used to manage foreign currency risk are measured at fair value and reported as assets or liabilities on the balance sheet. Following the termination of our cross currency swaps in July 2012, we have not elected to apply hedge accounting. Changes in fair value are recorded in Other (expense) income, net.
	J. Environmental and Other Contingent Liabilities: Accruals for environmental remediation, maintenance, and operating costs directly related to remediation, and other contingent liabilities are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Accruals for environmental liabilities and other contingent liabilities are recorded as Other noncurrent liabilities with amounts expected to be paid out in the next twelve months classified as Accrued expenses at undiscounted amounts.
	Insurance/Self-Insurance: It is our practice to conduct an analysis of our self-insured and insured contingent liabilities annually and whenever circumstances change significantly. Included in these liabilities are workers’ compensation, product liability, and toxic tort claims.
	Probable insurance recoveries for past and future indemnity costs are recorded in other receivables, to the extent collection is reasonably assured within the next twelve months, and longer term receivables are included in other assets at our best estimate of the ultimate expected receipts at undiscounted amounts. Defense and processing costs are expensed as incurred. Probable insurance recoveries for defense and processing costs are recognized only as actual costs are incurred.
	Asset Retirement Obligations: We recognize the fair value of the liability for an asset retirement obligation in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. The liability is accreted at the end of each period through charges to operating expense. If the obligation is settled for other than the carrying amount of the liability, we recognize a gain or loss on settlement.
	K. Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. If repatriation of the undistributed income of our international subsidiaries and associated companies is anticipated then income taxes are provided for such earnings. The undistributed earnings of all other foreign subsidiaries will be indefinitely reinvested in their operations.
	We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon settlement with the tax authorities. We recognize interest and penalties related to unrecognized tax benefits in income tax expense in the consolidated statements of income.
	L. Postretirement Benefits: Costs of postretirement benefits are recognized as employees render the services necessary to earn the related benefits. We recognize an asset or liability for the overfunded or underfunded status of postretirement plans that we sponsor. We measure plan assets and benefit obligations as of the date of the employer’s statement of financial position.
	We utilize the mark-to-market (“MTM”) method of accounting, under which our pension and other postemployment benefit (“OPEB”) costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; and 2) MTM gains and losses recognized annually, in the fourth quarter of each year, resulting from changes in actuarial assumptions and the differences between actual and expected returns on plan assets and discount rates. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized as an MTM adjustment in the quarter in which such remeasurement event occurs. For additional information, see Note 14, “Employee Benefit Plans.”
	M. Revenue Recognition: We recognize revenue when persuasive evidence of an arrangement exists, the selling price is fixed or determinable, collection is reasonably assured, and title and risk of loss has passed to our customers. Customer rebates are estimated and recognized as a reduction of sales as such rebates are being earned.
	N. Share-Based Compensation: We recognize our share-based compensation cost in an amount equal to the fair value of share-based payments and estimate a forfeiture rate for all share-based awards. We monitor share option exercise and employee termination patterns to estimate forfeiture rates within the valuation model.
	O. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions. These estimates or assumptions affect the reported amounts and disclosures. For example, estimates are used when accounting for allowance for doubtful accounts, inventory valuations, useful lives of tangible and intangible assets, recoverability of goodwill, accrued expenses, environmental and other contingent liabilities, pension and other postretirement benefits, income tax valuation allowances and assumptions utilized in determining share-based compensation. Actual results could differ from these estimates. Accounting estimates require the use of judgment regarding uncertain future events and their related effects and, accordingly, may change as additional information is obtained.
	P. New and Recently Adopted Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which will supersede current revenue recognition guidance in Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition.” The new standard is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions previously not addressed comprehensively, and clarify guidance for multiple-element arrangements. This new standard is effective for the first quarter of 2017 using one of two prescribed transition methods. We have not yet selected a transition method and continue to evaluate the impact this guidance will have on our future consolidated results of operations, financial condition, and related disclosures.
	In February 2013, the FASB issued ASU No. 2013-02. This ASU required us to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income–but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. It also required us to cross-reference to other disclosures currently required under U.S. GAAP for other reclassification items (that are not required under U.S. GAAP to be reclassified directly to net income in their entirety in the same reporting period). On January 1, 2013, we adopted the provisions of ASU No. 2013-02, which are reflected in these financial statements.
	Q. Reclassifications: Certain amounts, including changes in our equity structure, reported for prior years in the Consolidated Financial Statements and Notes to Consolidated Financial Statements have been reclassified to conform to the current year’s presentation.
	Except for the number of authorized shares and par value, all references to shares and per share data for all periods presented herein reflect the impact of the 2-for-1 stock split in the form of a stock dividend, which was effective in September 2014 (the “September 2014 stock split”). See Note 17 for additional information related to this stock split.
	In the consolidated statement of cash flows for the year ended December 31, 2013, we have corrected certain immaterial prior period misclassifications, which related to changes in accounts payable related to certain capital projects. These corrections resulted in a $4.9 increase to net cash provided by operating activities of continuing operations, and a $4.9 increase to net cash used in investing activities of continuing operations. The corrections did not impact our consolidated statement of income for the year ended December 31, 2013 or consolidated balance sheet as of December 31, 2013.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS
	Acquisition of Umeco plc
	On July 20, 2012, we completed the acquisition of all of the outstanding shares of Umeco plc (“Umeco”), an international provider of composite and process materials, in an all-cash transaction at a cost of approximately $423.8. The acquisition is intended to strengthen our position as a leading manufacturer of composite materials, while offering significant opportunities for growth and value creation, particularly in industrial composites and process materials. The acquired Umeco business is partly reported in the Aerospace Materials segment, but mostly reported in the Industrial Materials segment. Net sales from Umeco related to Industrial Materials and Aerospace Materials in 2012 were $124.7 and $25.3, respectively.
	The acquisition was accounted for under the acquisition method of accounting in accordance with the FASB’s ASC Topic 805, “Business Combinations.” As such, the Umeco assets acquired and liabilities assumed were recorded at their acquisition-date fair values. Acquisition-related transaction costs were not included as a component of consideration transferred, but were accounted for as an expense in the period in which the costs were incurred. Any excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed was allocated to goodwill.
	The following table summarizes the final assigned fair values of the assets acquired and liabilities assumed at the acquisition date.
	Cash	$	3
	Trade receivables	65.2
	Inventories	58.2
	Other current assets	25.5
	Plants, equipment and facilities	67.9
	Amortizable intangible assets	175.2
	Goodwill	186.7
	Deferred tax assets	1.2
	Other non-current assets	5.3
	Deferred tax liabilities	(52.1		)
	Other current and non-current liabilities	(112.3		)
	Total acquisition consideration allocation	$	423.8
	Goodwill recorded in connection with this acquisition was approximately $186.7, which represented the significant opportunities for growth and value creation by expanding our presence in the industrial composites sector, as well as the expected synergies from combining the acquired business with our existing business. Goodwill was assigned in part to the Aerospace Materials and Industrial Materials segments. The estimated amount of goodwill deductible for tax purposes over a 5 year period is $7.1. The estimated goodwill non-deductible for tax purposes is approximately $179.6.
	The following information provides details about the estimated step-up in fair value and/or the estimated fair value at the acquisition date for some key balance sheet items.
	Inventories
	As of the effective date of the acquisition, inventory acquired is required to be measured at fair value. Raw materials and work in process are valued at book value, which is assumed to be a reasonable proxy for fair value. The fair values for finished goods inventory were determined based on estimated selling prices less the sum of (a) costs of selling and (b) a reasonable profit allowance for the selling effort. The estimated net step-up in fair value for finished goods was $5.6.
	Deferred taxes
	In connection with the acquisition of Umeco, we acquired the stock of Umeco and therefore inherited the historical tax basis of its assets and liabilities, as well as its other tax attributes. As a result, we established deferred tax assets and liabilities with respect to the step-up to fair value of assets and liabilities for book purposes. We also inherited various tax uncertainties and valuation allowances, which were adjusted to reflect our judgments and estimates regarding the ultimate resolution of the items and consideration of the combined company activities.
	Property and equipment
	As of the effective date of the acquisition, property and equipment are required to be measured at fair value. It is assumed that all property and equipment will be used in a manner that represents the highest and best use of those assets. The fair value of land assets was primarily determined through use of the market approach, while the fair value of land improvements and personal property (machinery and equipment and fixed assets – other) was primarily determined through use of the cost approach and corroborated with an income approach when appropriate. Our fair value adjustment to property and equipment has been made by obtaining an understanding of the nature, amount, and type of Umeco property and equipment as of July 20, 2012. The estimated step-up in fair value for property and equipment was $4.9.
	Intangible assets include the following:
		Estimated			Remaining
		Fair Value			Useful Lives
					(Years)
	Customer relationships	$	141.9		16
	Technology—Structural Materials: Aerospace & Defense	$	14.3		21
	Technology—Structural Materials: Other industries	$	9.2		6
	Trademarks and trade names	$	9.8		8
	It is assumed that all intangible assets will be used in a manner that represents the highest and best use of those assets. The fair value of intangible assets was determined primarily using income approaches. This included the multi-period excess earnings valuation method for customer relationships and the relief-from-royalty valuation method for trademarks and trade names, and technology assets. Some of the more significant assumptions used in the development of intangible asset values, as applicable, include the amount and timing of projected future cash flows (including net sales, cost of sales, marketing, administrative and development expenses and working capital); the discount rate selected to measure the risks inherent in the future cash flows; the assessment of the asset’s life cycle and the competitive trends impacting the asset; and royalty rates.
	The fair value of the assets acquired included trade receivables of $65.2, virtually all of which has been collected.
	For the year ended December 31, 2012, we recognized expenses for acquisition related costs of approximately $8.4. These costs are included in Administrative and general in the consolidated statement of income for the period ended December 31, 2012. From the acquisition date through December 31, 2012, we recorded net sales of $150.0 for the Umeco businesses, and corresponding net operating earnings of $1.0, which includes the expensing of the aforementioned net step-up in fair value for purchased finished goods of $5.6.
	The assets and liabilities arising from contingencies recognized as of the acquisition date are not significant to the consolidated financial statements.
	Pro forma financial information (unaudited)
	The results of operations of Umeco have been included in the consolidated statements of operations since the acquisition date of July 20, 2012.
	The following table reflects the unaudited pro forma consolidated results of operations as if the acquisition had taken place on January 1, 2012, as adjusted by our September 2014 stock split:
	Year ended December 31,	2012
	Net revenue	$	1,896.20
	Earnings from continuing operations	$	93.7
	Diluted earnings per share from continuing operations	$	1
	These amounts have been calculated after applying Cytec’s accounting policies and adjusting the results of Umeco to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant, and equipment, and intangible assets had been applied from January 1, 2011 with the consequential tax effects. We did not apply MTM accounting to the Umeco pension plans prior to the acquisition for these pro forma results.
	For the year ended December 31, 2012, material non-recurring pro forma adjustments include the removal of costs related to the acquisition of Umeco of $20.2 including $11.8 of transaction related costs included in legacy Umeco’s consolidated statement of operations for the year ended December 31, 2012.
	The unaudited pro forma information does not include any adjustments for any restructuring activities, operating efficiencies or cost savings.
	Acquisition of manufacturing assets of Star Orechem International Private Limited
	On March 30, 2012, we acquired the manufacturing assets of Star Orechem International Private Limited (“SOIL”), in Nagpur, Central India, in a cash transaction. We completed capabilities and upgrading project of the acquired plant to meet appropriate safety and operating standards, and began production of our mining chemical products in the fourth quarter of 2014. The results of operations of the acquired business have been included in our In Process Separation segment since April 1, 2012. The acquisition was funded from our cash on hand and has been accounted for as an acquisition of a business.
	The following table summarizes the final assigned fair values of the assets acquired and liabilities assumed as of March 30, 2012:
	Inventories	$	1.1
	Other current assets	0.4
	Plants, equipment and facility	6.5
	Identifiable intangibles	1.2
	Goodwill	20.8
	Other, net	0.2
	Total purchase price	$	30.2
	The goodwill recorded in connection with this acquisition is largely attributable to the capacity and potential for future strategic growth. All $20.8 of the goodwill recognized is expected to be deductible for income tax purposes.
	The amount allocated to intangibles represents the fair value of non-compete agreements, which were determined based on an independent appraisal. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 fair value measurement.
	There were no material revenues or earnings related to SOIL included in our consolidated statement of income for the year ended December 31, 2012.

	-2	Income tax expense on discontinued operations for the year ended December 31, 2012 includes a $7.6 of tax expense on estimated unrepatriated earnings of international subsidiaries from the anticipated sale of Coatings.
	-3	The assets and liabilities of the Coatings business were reclassified to held-for-sale effective June 30, 2012. Accordingly, depreciation and amortization were no longer recorded on these assets beginning July 1, 2012.
	Discontinued operations
	Coating Resins
	On April 3, 2013, we completed the divestiture of our remaining Coating Resins (“Coatings”) business to Advent International (“Advent”), a global private equity firm, for a total value of $1,133.0, including assumed liabilities of $118.0, resulting in a cumulative after-tax loss on the sale of $16.9 in 2013. These cumulative after-tax losses are included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statement of income for 2013. The final price paid and loss on sale remains subject to final working capital and other customary adjustments. After-tax earnings from operations of the discontinued business for the years ended December 31, 2013 and 2012 were $31.6 and $117.4, respectively.
	In connection with the sale of Coatings to Advent, we agreed to retain certain liabilities, including liabilities for U.S. pension and other postretirement benefits and certain tax liabilities related to taxable periods (or portions thereof) ending on or before April 3, 2013. In 2014, we recorded after-tax charges of $1.0 related to certain of these tax liabilities and other tax related adjustments with respect to the divestiture. Additionally, in 2014, we recorded a tax benefit of $11.1 based on our best estimate of the purchase price allocation attributable to the Coatings business sold in various taxing jurisdictions, offset by after-tax charges of approximately $3.6 for purchase price and working capital adjustments and charges of $0.6 to true up the tax expense related to the divestiture.
	Previously, on July 31, 2012, we completed the sale of the pressure sensitive adhesives (“PSA”) product line of the former Coatings business to Henkel AG & Co. for approximately $105.0, including working capital of approximately $15.0. In 2012, we received cash consideration of $112.8 from the sale and recorded an after-tax gain on the sale of $8.6, which is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statements of income. In 2012, we also recorded cumulative after-tax charges of $24.7 to adjust our carrying value of the Coatings disposal group to its fair value less cost to sell, based on the terms of the definitive agreement with Advent at that time. The charge is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statement of income for 2012.
	The results of operations of the former Coatings business have been reported as discontinued operations, and are therefore excluded from both continuing operations and segment results for all periods presented. All previously reported financial information has been revised to conform to the current presentation.
	Other divestitures
	Industrial Materials distribution product line
	On July 12, 2013, we sold the Industrial Materials distribution product line, which we acquired as part of the Umeco acquisition, to Cathay Investments for $8.6, subject to final working capital and other customary adjustments. In 2013, we recorded an after-tax charge of $12.5 to adjust our carrying value of the disposal group to its fair value less cost to sell, based on the terms of the agreement. The charge is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statements of income. In 2014, we recorded an after-tax benefit of $0.2 related to final purchase price and settlement of final working capital adjustments. These amounts are included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statements of income.
	The results of operations of the former Industrial Materials distribution product line prior to its divestiture remain in continuing operations for all periods presented, as the results of operations for the business and assets and liabilities sold were not material to disclose as discontinued operations or assets held for sale.
	Former Umeco entities divested prior to our acquisition
	As part of our acquisition accounting for Umeco in 2012, we established reserves related to income tax and value added tax liabilities of an entity that had been divested by Umeco in 2011, for periods that were under audit prior to it its divestiture. We continued to accrue interest through the end of 2013. In 2014, we agreed to a settlement for audit periods through March 31, 2009, which resulted in a benefit of approximately $3.6. The benefit is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statement of income for the year ended December 31, 2014.
	Stamford research and development facility
	On September 30, 2011, we sold our Stamford, Connecticut research and development facility for $11.0 cash. The transaction included the leaseback of certain portions of the facility for a 7-year period, with an option to extend the lease for an additional 3 years. As part of the agreement, we were responsible for the remediation of certain environmental matters at the site and therefore, as a result of the environmental remediation obligation, we were precluded from recognizing the sale until the remediation was completed. On the date of the transaction, the carrying value of the facility exceeded the proceeds received by $21.5. However, since the facility supports the operations of multiple asset groupings that had sufficient undiscounted cash flows to support the in-use value of the facility, no impairment charge was recorded at that time. Therefore, in the fourth quarter of 2011, we adjusted the estimated remaining useful life of the facility to the 7-year initial lease period and began accelerating the depreciation over that period. In the fourth quarter of 2012, we completed remediation and recognized the sale. As a result, we recorded a pre-tax loss of $16.7 in 2012 for the remaining excess carrying value, which is included in Net loss on sale of assets in the consolidated statements of income.

	In accordance with our accounting policy, restructuring costs are included in our corporate and unallocated operating results for segment reporting purposes, which is consistent with management’s view of its businesses. Aggregate pre-tax restructuring charges (credits) included in the consolidated statements of income were recorded by line item as follows:
		2014			2013			2012

	Asset impairment charge	—			2.8			—
	Total	$	1		$	6.9		$	21.2
	Details of our 2013 restructuring initiatives are as follows:
	In the third quarter of 2013, we launched cost reduction initiatives in our Industrial Materials segment to address market conditions and better position ourselves for profitable growth. The plan included headcount reductions of approximately 55 people, through modification of shift patterns within various operations, centralization of logistics and planning activities, and closure of a small site in Beelitz, Germany. The plan resulted in a pre-tax restructuring charge of approximately $4.5 related mainly to severance costs and the closure of the manufacturing facility. The initiative is expected to be completed by 2015.
	In the second quarter of 2013, we launched initiatives in our Aerospace Materials segment to move all production operations from the Costa Mesa, Adelanto, and Huntington Beach, California sites into the Winona, Minnesota, Tulsa, Oklahoma, and Anaheim, California locations. Approximately 120 employees will be impacted by this move. These plans resulted in a restructuring charge of $1.6, primarily for severance, retention costs, and accelerated depreciation. The initiatives are expected to be completed in waves by the first quarter of 2015 and paid for by mid-2015.
	During 2014, we recorded an additional charge of $1.4 to these initiatives. The remaining reserve relating to the 2013 restructuring initiatives at December 31, 2014 is $1.8.
	Details of our 2012 restructuring initiatives are as follows:
	In the third quarter of 2012, we approved plans to realign the supporting structure of our Aerospace Materials and Industrial Materials segments to take advantage of synergies from the acquisition of Umeco. These plans resulted in a restructuring charge of $6.6 related to the severance of 28 positions. The initiatives were substantially completed in 2013 and are expected to be paid by the end of 2015.
	In the second quarter of 2012, we launched initiatives in our corporate functions across sales, marketing, manufacturing, supply chain, research and development, and administrative functions to mitigate continuing costs following the anticipated sale of Coatings. These initiatives resulted in charges related to severance and employee benefits of $14.7 associated with the elimination of 171 positions. These initiatives are expected to be substantially completed and paid in early 2016, but may carry over into later periods.
	During 2013, we recorded an additional charge of $0.9 to these initiatives and during 2014, we recorded a favorable adjustment of $0.4 to these initiatives. The remaining reserve relating to the 2012 restructuring initiatives at December 31, 2014 is $3.2.

SHAREBASED_COMPENSATION

SHARE-BASED COMPENSATION	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION
	Shares and per share data below have been adjusted for all periods to reflect the effects of our September 2014 stock split. See Note 17 for additional information related to this stock split.
	The fair value of each option or stock-settled share appreciation right (“SARS”) award is estimated on the date of grant using a binomial-lattice option valuation model. Stock-settled SARS are economically valued the same as stock options. The binomial-lattice model takes into account variables such as volatility, dividend yield, and risk-free interest rate. In addition, the binomial-lattice model considers the contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life, and the probability of termination or retirement of the option holder in computing the value of the option.
	The weighted average assumptions for the years ended December 31, 2014, 2013 and 2012, including the weighted-average fair value per option retroactively as adjusted by our September 2014 stock split, are noted in the following table:
			2014				2013			2012
	Expected life (years)		6.3				6.2			6.2
	Expected volatility		34.6		%		36.2		%	41.9		%
	Expected dividend yield		0.63		%		0.78		%	1.01		%
	Risk-free interest rate		3		%		1.86		%	2.11		%
	Weighted-average fair value per option		$	16.46			$	13.28		$	9.95
	The expected life of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. Expected volatilities are based on the combination of implied market volatility and our historical volatility. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. As share-based compensation recognized in the consolidated statement of income is based on awards ultimately expected to vest, we incorporate the probability of pre-vesting forfeiture in determining the number of expected vested options. The forfeiture rate is based on the historical forfeiture experience and prospective actuarial analysis.
	Stock Award and Incentive Plan:
	The 1993 Stock Award and Incentive Plan, as amended on January 31, 2012, (the “1993 Plan” or “Amended Plan”) provides for grants of a variety of awards, such as stock options (including incentive stock options and nonqualified stock options), nonvested stock (including performance stock), SARS (including those settled with common shares), and deferred stock awards and dividend equivalents.
	At December 31, 2014, there were approximately 8,000,000 shares reserved for issuance under the 1993 Plan, inclusive of 3,400,000 shares reserved for issuance for all outstanding share-based compensation grants.
	Stock options and stock-settled SARS
	We have utilized the stock option component of the 1993 Plan to provide for the granting of nonqualified stock options and stock-settled SARS with an exercise price at 100% of the market price on the date of the grant. Options and stock-settled SARS are generally exercisable in installments of one-third per year commencing one year after the date of grant and annually thereafter, with contract lives of generally ten years from the date of grant.
	A summary of stock options and stock-settled SARS activity for the year ended December 31, 2014 has been retroactively adjusted to reflect the effects of our September 2014 stock split and is presented below:
	Options and Stock-Settled SARS Activity:	Number			Weighted				Weighted	Aggregate
		of Units			Average				Average	Intrinsic
					Exercise				Remaining	Value
					Price Per				Contractual
					Unit				Life (Years)
	Outstanding at January 1, 2014	3,898,092			$	24.96
	Granted	566,850			44.39
	Exercised	(1,418,398	)		24.31
	Forfeited	(136,068	)		34.15
	Outstanding at December 31, 2014	2,910,476			$	28.62			6.2	$	51.2
	Exercisable at December 31, 2014	1,825,798			$	22.97			4.9	$	42.4
	During the year ended December 31, 2014, we granted 566,850 stock options. The weighted-average grant-date fair value of stock options and the stock-settled SARS granted during the years ended December 31, 2014, 2013 and 2012, was $16.46, $13.28, and $9.95 per share, respectively. Total pre-tax compensation cost related to stock option and stock-settled SARS was $7.9, $7.7, and $7.6 during the years ended December 31, 2014, 2013 and 2012, respectively. The total intrinsic value of stock options and stock-settled SARS exercised during the years ended December 31, 2014, 2013 and 2012 was $33.4, $27.5, and $26.3 respectively. Treasury shares and newly issued shares have been utilized for stock option and stock-settled SARS exercises.
	As of December 31, 2014, there was approximately $5.9 of total unrecognized compensation cost related to stock options and stock-settled SARS. That cost is expected to be recognized over a weighted-average period of 1.3 years as the majority of our awards vest over 3 years.
	Total tax benefits realized from share-based awards was $12.1, $9.7, and $8.0 for the years ended December 31, 2014, 2013 and 2012, respectively. Cash received from stock options exercised was $15.4, $23.5, and $28.0 for the years ended December 31, 2014, 2013 and 2012, respectively.
	Cash-settled SARS
	Our 1993 Plan also provides for the granting of cash-settled SARS, which were granted during 2004 and 2005. Cash-settled SARS are liability-classified awards. Cash used to settle cash-settled SARS was $0.8, $1.4, and $0.8 for the years ended December 31, 2014, 2013 and 2012, respectively. Cash-settled SARS are exercisable in installments of one-third per year commencing one year after the date of grant and annually thereafter, with contractual lives of ten years from the date of grant. The total amount of before-tax (income)/expense recognized for cash-settled SARS was $(0.1), $0.9, and $1.2 for the years ended December 31, 2014, 2013 and 2012, respectively. The liability related to our cash-settled SARS was $0.2 and $1.2 at December 31, 2014 and 2013, respectively.
	Nonvested stock, nonvested stock units, and performance stock
	As provided under the 1993 Plan, we have also issued nonvested stock, nonvested stock units, and performance stock. Nonvested stock and stock units are subject to certain restrictions on ownership and transferability that lapse upon vesting. Performance stock payouts are based on the attainment of certain financial performance objectives and may vary depending on the degree to which the performance objectives are met. We did not grant any performance stock in 2014, 2013 and 2012.
	A summary of nonvested stock and nonvested stock units for the year ended December 31, 2014 has been retroactively adjusted to reflect the effects of our September 2014 stock split and is presented below:
	Nonvested Stock and Nonvested Stock Units:	Number			Weighted Average
		of Units			Grant Date
					Fair Value Per Unit
	Nonvested at January 1, 2014	316,766			$	28.82
	Granted	95,486			44.97
	Vested	(102,348	)		26.12
	Forfeited	(17,032	)		33.69
	Nonvested at December 31, 2014	292,872			$	34.75
	During 2014, we granted 73,480 nonvested stock units to employees and 22,006 shares of nonvested stock primarily to nine directors, which generally vest on the third anniversary of the date of grant. The weighted average fair value of the nonvested stock and nonvested stock units on the date of grant was $44.97 per share, which was equal to the closing market price of our stock on the date of the grant. The total amount of share-based compensation expense recognized for nonvested stock and nonvested stock units was $3.5, $3.5, and $3.4 for the years ended December 31, 2014, 2013 and 2012, respectively. As of December 31, 2014, there was $3.2 of total unrecognized compensation cost related to nonvested stock and nonvested stock units. That cost is expected to be recognized over a weighted-average period of 1.8 years.
	Compensation cost related to all share based compensation arrangements capitalized in inventory as of December 31, 2014 and 2013 was approximately $0.5 in both years.
	For awards granted prior to January 1, 2012, in the event of a “change in control” (as defined in the Amended Plan), unless specifically provided to the contrary in an award agreement or grant letter establishing an award, (i) any award carrying a right to exercise that was not previously exercisable and vested will become fully exercisable and vested, (ii) the restrictions, deferral limitations, payment conditions and forfeiture applicable to any other award, including non-employee directors’ awards, granted under the amended Plan will lapse, and such awards will be deemed fully vested, and (iii) any performance conditions imposed with respect to awards (other than annual cash incentives) shall be deemed to be fully achieved. For awards granted on or after January 1, 2012, if after a “change in control” (as defined in the Amended Plan) the recipient’s employment or independent contractor relationship is terminated by the Company within two (2) years after the change of control without cause, or by such recipient for “good reason” (as defined in the Amended Plan) unless specifically provided to the contrary in an award agreement or grant letter establishing an award, (i) any award carrying a right to exercise that was not previously exercisable and vested will become fully exercisable and vested, (ii) the restrictions, deferral limitations, payment conditions and forfeiture applicable to any other award granted under the Amended Plan will lapse, and such awards will be deemed fully vested, and (iii) any performance conditions imposed with respect to awards (other than annual cash incentives) shall be deemed to be fully achieved.
	As of December 31, 2014 and 2013, our Additional paid-in capital pool (“APIC Pool”) which represents excess tax benefits available to absorb potential future tax deficiencies was $89.6 and $81.7, respectively.
	In the second quarter of 2012, in an effort to retain key employees of the Coatings business who could be impacted by the potential sale of Coatings, we agreed that if any such individual’s employment with Cytec is terminated as a result of a sale of Coatings, we would pay such employee an amount equal to the intrinsic value of any unvested stock options and restricted stock units based on the closing price of Cytec stock on the date of the sale. As of June 30, 2012, when we determined we had met all the criteria for discontinued operations, we determined that certain unvested stock options and restricted stock units that had been accounted for as equity awards should be reclassified to be accounted for as liability awards.
	Accordingly, we recorded a liability of $2.9 for these awards at June 30, 2012 by reclassifying $1.7 of previously recognized expense out of Additional paid-in capital and recognized $1.2 of additional expense. In the second half of 2012, an additional $3.7 of expense was recognized related to these awards. During the fourth quarter of 2012, new facts and circumstances regarding the timing of the close of the Coatings sale indicated that a portion of the awards previously reclassified to liability awards would vest prior to closing and were reclassified back to equity awards. Accordingly, we reclassified $2.3 from the liability to Additional paid-in capital. The expense recorded for these liability awards was recognized in Earnings from operations of discontinued business, net of tax on the consolidated statements of income.

Earnings Per Share [Abstract]
Earnings Per Share (EPS)	EARNINGS PER SHARE (EPS)
	Basic earnings per common share excludes dilution and is computed by dividing net earnings available to common stockholders by the weighted-average number of common shares outstanding (which includes shares outstanding, less performance and nonvested shares for which vesting criteria have not been met) plus deferred stock awards, weighted for the period outstanding. Diluted earnings per common share is computed by dividing net earnings available to common stockholders by the sum of the weighted-average number of common shares outstanding for the period adjusted (i.e., increased) for all additional common shares that would have been outstanding if potentially dilutive common shares had been issued and any proceeds of the issuance had been used to repurchase common stock at the average market price during the period. Under this method, an increase in the fair market value of the Company’s stock can result in a greater dilutive effect from potentially dilutive common shares. The proceeds are assumed to be the sum of the amount to be paid to the Company upon exercise of options, the amount of compensation cost attributed to future services and not yet recognized, and the amount of income taxes that would be credited to or deducted from capital upon exercise.
	All share and per share data for the periods presented below reflect the effects of our September 2014 stock split. See Note 17 for additional information related to this stock split.
	The following table sets forth the computation of basic and diluted earnings per common share for the years ended December 31, 2014, 2013 and 2012 (in thousands, except net earnings in millions and per share amounts):

	Foreign Currency Derivative and Hedging Activities
	Currency forward contracts
	We periodically enter into currency forward contracts primarily to hedge currency fluctuations of transactions denominated in currencies other than the functional currency of the respective entity. At December 31, 2014, the principal transactions hedged involved accounts receivable and accounts payable. When hedging currency exposures, our practice is to economically hedge such exposures with forward contracts denominated in the same currency and with similar critical terms as the underlying exposure, and therefore, the instruments are effective at generating offsetting changes in the fair value, cash flows, or future earnings of the hedged item or transaction. The fair values of forward contracts are calculated each period. These forward contracts are not defined as hedging instruments and therefore, all changes in fair values are reported in Other (expense) income, net.
	At December 31, 2014, net contractual amounts of forward contracts outstanding translated into USD totaled $246.3. Of this total, $178.4 was attributed to the exposure in forward selling/purchase of USD, and $67.9 was attributable to the exposure in forward selling/purchase of Euros, translated into USD equivalent amounts. The net (unfavorable) favorable fair values of currency contracts, based on forward exchange rates at December 31, 2014 and 2013 were $(6.1) and $1.4, respectively.
	At December 31, 2014 and 2013, the currency and net notional amounts of forward contracts outstanding translated into USD equivalent amounts were as follows:

	Cross currency swaps
	We have used cross currency swaps to hedge the changes in the cash flows of certain Euro denominated intercompany loans receivable held by U.S. entities and, until the sale of our Coatings business, to hedge a portion of our net investment in Cytec Surface Specialties SA/NV (formerly, our largest Euro functional currency subsidiary).
	In July 2012, we terminated all of our outstanding cross currency swaps to take advantage of the declining value of the Euro and to prepare for the anticipated divestiture of Coatings. The final payment of approximately $1.8 to settle the swaps was based on the fair value of the swaps at the time of termination.
	Prior to the termination of the swaps, the fair value of our swaps was calculated each period with changes in fair value reported in foreign currency translation adjustments within accumulated other comprehensive income (loss), net of tax. Such amounts reclassified to translation adjustments remained in other comprehensive income (loss) until the divestiture of Coatings, which included our investment in Cytec Surface Specialties SA/NV, on April 3, 2013. Until then, we monitored the counterparty credit risk and the continued probability of the hedged cash flows as to amount and timing. See Note 15, “Comprehensive Income,” for further details on the amounts reclassified out of other comprehensive income as related to the divestiture of Coatings.
	Credit Risk
	At December 31, 2014, we did not have derivative instruments that contained credit-related-risk contingent features or provisions that would trigger immediate settlement or require us to post collateral to our counterparties. Also as of December 31, 2014, we did not have any significant concentration of credit risk arising from our derivative instruments.
	The following table summarizes the impact of derivative instruments on our consolidated balance sheets:
		Asset Derivatives											Liability Derivatives

	Fair Value Measurements
	We have certain assets and liabilities that are carried at fair value on a recurring basis in the financial statements, for which we determine the appropriate level in the fair value hierarchy for each fair value measurement. The fair value hierarchy prioritizes the inputs, which refer broadly to assumptions market participants would use in pricing an asset or liability, into three levels. It gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The level in the fair value hierarchy within which a fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, interest rates, exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability.
	All of our derivatives are valued based on Level 2 inputs. Our currency forwards are valued based on readily available published indices for currency exchange rates.
	A summary of the fair value measurements for each major category of derivatives at December 31, 2014 is outlined in the table below:
	Description	Significant Other
		Observable
		Inputs (Level 2)
	Currency forwards	$	(6.1	)
	As of December 31, 2014, we did not have any non-financial assets and liabilities that are carried at fair value on a recurring basis in the consolidated financial statements for which a fair value measurement was required for the year ended December 31, 2014.

	In conjunction with our segment realignment in 2013, we completed a goodwill impairment test in the first quarter of 2013 and concluded that there was no impairment. An additional goodwill impairment test was triggered at the end of the second quarter of 2013 because of the reduction in the outlook for Industrial Materials’ 2013 financial results, resulting from a deterioration in market conditions in Europe and the after-tax charge of $12.5 related to the sale of the distribution product line, which was part of the Industrial Materials segment. See Note 3 for a further discussion of the sale of the Industrial Materials distribution product line. We again concluded there was no impairment.
	In the fourth quarters of 2014, 2013 and 2012, we completed our required annual impairment test and concluded that there was no impairment.

	Debt issuance and repurchases
	On November 12, 2014, we issued $250.0 aggregate principal amount of 3.95% senior unsecured notes due May 1, 2025 (“3.95% notes”), which resulted in $248.3 in net proceeds after original issue discount and underwriting fees. In addition, on November 5, 2014, we commenced offers to purchase our 6.0% notes due October 1, 2015 (“6.0% notes”) and a portion of our 8.95% notes due July 1, 2017 (“8.95% notes”). In November 2014, we applied the net proceeds from the issuance of the 3.95% notes to repurchase $17.8 principal amount of our 6.0% notes for a purchase price of $18.7 plus accrued interest of $0.1. In December 2014, we applied the balance of the net proceeds as follows: (1) to repurchase $124.0 principal amount of our 6.0% notes for a purchase price of $129.6 plus accrued interest of $1.3; and (2) to repurchase $82.0 principal amount of our 8.95% notes for a purchase price of $97.8 plus accrued interest of $3.1. The repurchase of the 6.0% and 8.95% notes resulted in a loss of $22.7 in 2014, including transaction costs.
	On March 12, 2013, we issued $400.0 aggregate principal amount of 3.5% senior unsecured notes due April 1, 2023 (“3.5% notes”), which resulted in $394.6 in net proceeds after original issue discount and underwriting fees. In addition, on February 26, 2013, we called for the redemption of our 4.6% notes due July 1, 2013 (“4.6% notes”), and commenced offers to purchase our 6.0% notes and our 8.95% notes. In March 2013, we applied the net proceeds from the issuance of the 3.5% notes as follows: (1) to redeem all $135.2 principal amount of our 4.6% notes for a purchase price of $136.8 plus accrued interest of $1.5; (2) to repurchase $107.8 principal amount of our 6.0% notes for a purchase price of $121.1 plus accrued interest of $3.1; and (3) to repurchase $85.1 principal amount of our 8.95% notes for a purchase price of $108.3 plus accrued interest of $1.8. The redemption of the 4.6% notes and repurchase of the 6.0% and 8.95% notes resulted in a loss of $39.4 in 2013, including transaction costs.
	During 2012, we repurchased portions of our 6.0% notes due October 1, 2015 with a total carrying value of $0.4 for a total purchase price of $0.5 including accrued interest, resulting in a loss of less than $0.1. During 2012, we also repurchased portions of our 8.95% notes due July 1, 2017 with a total carrying value of $0.6 for a total purchase price of $0.8 including accrued interest, resulting in a loss of $0.2.
	The net losses from our 2014, 2013 and 2012 debt repurchases are included in Net loss on early extinguishment of debt in the accompanying consolidated statements of income.
	Revolving credit facility
	On June 24, 2014, under the terms of our existing Five Year Credit Agreement (the “Revolving Credit Facility”), we extended the term one year to June 28, 2019.
	On June 28, 2013, we amended and restated the Revolving Credit Facility. The material terms and conditions remain substantially similar to the prior agreement except as set forth below. As the result of the amendment and restatement, the maximum amount we may borrow under the Revolving Credit Facility continues to be $400.0 with a $25.0 swingline, and the term was extended to June 28, 2018. Subject to the consent of the lenders, we have the ability under certain circumstances to extend the term through June 28, 2021 and to increase the maximum amount we may borrow under the Revolving Credit Facility up to $500.0.
	In the second quarter of 2012, we had a net draw down of $170.0 from our Revolving Credit Facility for the purposes of funding the Umeco transaction. In April 2013, upon receiving proceeds from the close of the sale of Coatings, we repaid the outstanding portion of the Revolving Credit Facility. There was no outstanding balance on the facility as of December 31, 2014. At December 31, 2014, $400.0 was available for borrowing under the Revolving Credit Facility. We are required to comply with certain customary financial covenants under the facility: (i) the ratio of consolidated total debt to consolidated EBITDA, and (ii) the ratio of consolidated EBITDA to consolidated interest expense. We are in compliance with these covenants and expect to be in compliance for the foreseeable future.
	Fair value
	At December 31, 2014 and 2013, the fair value of our long-term debt, including the current portion, was $761.5 and $731.2, respectively. The fair value is based on a discounted cash flow analysis, which incorporates the contractual terms of the notes, and observable market-based inputs that include time value, interest rate curves, and credit spreads.
	Non-U.S. credit facilities
	At December 31, 2014 and 2013, we had approximately $6.2 and $7.3, respectively, of non-U.S. credit facilities, which are renewable annually. There were outstanding borrowings of $0.1 and $0.5 under these facilities at December 31, 2014 and 2013, respectively.
	Interest
	The weighted average interest rate on all of our debt was 4.35% for 2014 and 5.3% for 2013. There were no short-term borrowings outstanding as of December 31, 2014 and 2013.
	Cash payments during the years ended December 31, 2014, 2013 and 2012, included interest of $41.9, $44.6, and $43.5, respectively. Included in Interest expense, net, in the accompanying consolidated statements of income for the years ended December 31, 2014, 2013 and 2012, was interest income of $0.4, $1.4, and $3.8, respectively. Capitalized interest for the years ended December 31, 2014 and 2013 was $24.3 and $21.6, respectively.
	Maturities
	Maturities of long-term debt for the next five years and thereafter are as follows:

Commitments and Contingencies Disclosure [Abstract]
Environmental, Contingencies and Commitments	ENVIRONMENTAL, CONTINGENCIES AND COMMITMENTS
	Environmental and Related Matters
	We are subject to substantial costs arising out of environmental laws and regulations, which include obligations to remove or limit the effects on the environment of the disposal or release of certain wastes or substances at various sites or to pay compensation to others for doing so.
	Our most significant environmental liabilities relate to remediation and regulatory closure obligations at manufacturing sites now or formerly owned by us. We are also involved in legal proceedings directed at the cleanup of various other sites, including a number of federal or state Superfund sites. Because the laws pertaining to Superfund sites generally impose retroactive, strict, joint and several liability, a governmental plaintiff could seek to recover all remediation costs at any such site from any of the potentially responsible parties (“PRPs”) for such site, including us, despite the involvement of other PRPs. In some cases, we are one of several hundred identified PRPs, while in others we are the only one or one of only a few. Generally, where there are a number of financially solvent PRPs, liability has been apportioned, or we believe, based on our experience with such matters, that liability will be apportioned based on the type and amount of waste disposed by each PRP at such disposal site and the number of financially solvent PRPs. In many cases, the nature of future environmental expenditures cannot be quantified with accuracy. In addition, from time to time in the ordinary course of our business, we are informed of, and receive inquiries with respect to, additional sites that may be environmentally impaired and for which we may be responsible.
	As of December 31, 2014 and 2013, the aggregate environmental related accruals were $59.5 and $63.1, respectively, of which $9.5 and $11.9 was included in accrued expenses, with the remainder of $50.0 and $51.2 included in other noncurrent liabilities, respectively. Environmental remediation spending for the years ended December 31, 2014, 2013 and 2012, was $7.0, $8.7, and $3.9, respectively.
	Our process is to review our environmental remediation accruals quarterly and based on new information, we may from time to time adjust our environmental related accruals. Overall, our adjustments resulted in a net increase of $4.2 in our environmental accruals for the year ended December 31, 2014, of which $2.4 related to an inactive U.S. site to revise its projected remediation costs based on a revised Closure Plan approved by the Florida Department of Environmental Protection and $1.8 related primarily to several U.S. and European sites.
	Our environmental related accruals can change substantially due to such factors as additional information on the nature or extent of contamination, methods of remediation required, changes in the apportionment of costs among responsible parties, and other actions by governmental agencies or private parties, or if we are named in a new matter and determine that an accrual needs to be provided, or if we determine that we are not liable and no longer require an accrual.
	Piles Creek
	We were notified by the National Oceanic and Atmospheric Administration (“NOAA”), a federal natural resource trustee, that, after an environmental assessment, we are one of six parties potentially responsible for damages to natural resources in Piles Creek, a tidal influenced tributary partially running through an industrial area in Linden, New Jersey. A portion of Piles Creek runs adjacent to our previously closed landfill in Linden, New Jersey. NOAA further advised that it seeks compensation from the six PRPs in the form of restoring other tidal wetlands. Thus far, no legal action has been taken by NOAA and we are investigating our contribution, if any, to this matter. Accordingly, no loss contingency has been recorded.
	Asset Retirement Obligations
	The fair value of a liability for an asset retirement obligation is recognized in the period in which the liability is incurred and becomes determinable with an offsetting increase in the carrying amount of the related long-lived asset. The recognition of an asset retirement obligation at fair value requires that management make numerous estimates, assumptions and judgments regarding such factors as the estimated probabilities, amounts and timing of settlements, the credit-adjusted risk-free rate to be used, inflation rates, market risk-premium, and changes in environmental, regulatory, and legal environments. In periods subsequent to initial measurement of the liability, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions such as the timing or the amount of the original estimate of undiscounted cash flows. Over time, the liability is accreted to its future value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we either settle the obligation for its recorded amount or incur a gain or loss.
	A summary of the changes in the asset retirement obligation for the years ended December 31, 2014 and 2013 is presented below:
	Asset retirement obligation at December 31, 2012	$	15.9
	Liabilities incurred	2.5
	Liabilities settled	(0.5		)
	Accretion expense	1
	Revision in estimated cash flows	(1.7		)
	Currency exchange	0.1
	Asset retirement obligation at December 31, 2013	$	17.3
	Liabilities incurred	—
	Liabilities settled	(0.5		)
	Accretion expense	0.9
	Revision in estimated cash flows	(2.2		)
	Currency exchange	(0.3		)
	Asset retirement obligation at December 31, 2014	$	15.2
	Our long-lived assets subject to asset retirement obligations are primarily related to asbestos abatement and Resource Conservation and Recovery Act (“RCRA”) closures at certain manufacturing and research facilities. As of December 31, 2014, 22 of our sites have been identified with regulatory closure obligations. Assets subject to asset retirement obligations are primarily manufacturing and research facilities, related equipment, and storage tanks. We are also obligated to return certain land to its original condition upon vacating.
	There are no sites with a regulatory closure obligation for which a liability has not been estimated and recorded.
	At December 31, 2014, there were no assets legally restricted for purposes of settling asset retirement obligations. The asset retirement obligation liability has been recorded as Other noncurrent liabilities in the accompanying consolidated balance sheets.
	Other Contingencies
	We are the subject of numerous lawsuits and claims incidental to the conduct of our or certain of our predecessors’ businesses, including lawsuits and claims relating to product liability and personal injury, including asbestos, environmental, contractual, employment and intellectual property matters.
	As of December 31, 2014 and 2013, the aggregate self-insured and insured contingent liability was $45.9 and $46.9, respectively, and the related insurance recovery receivable for the liability as well as claims for past payments was $19.7 and $20.0, respectively. The asbestos liability included in the above amounts at December 31, 2014 and 2013 was $36.5 and $37.9, respectively, and the insurance receivable related to the liability as well as past payments was $19.3 and $19.6, respectively. A net deferred tax benefit has been recognized for those claims for which full insurance recovery is not expected.
	Asbestos
	We, like many other industrial companies, have been named as one of hundreds of defendants in a number of lawsuits filed in the U.S. by persons alleging bodily injury from asbestos. The claimants allege exposure to asbestos at facilities that we own or formerly owned or from products that we formerly manufactured for specialized applications. Most of these cases involve numerous defendants, sometimes as many as several hundred. Historically, most of the closed asbestos claims against us have been dismissed without any indemnity payment by us; however, we can make no assurances that this pattern will continue.
	The following table presents information about asbestos claims activity:
	Years ended December 31,	2014			2013
	Number of claimants at beginning of period	8,100			8,000
	Number of claimants associated with claims closed during period	(3,000	)		(100	)
	Number of claimants associated with claims opened during period	100			200
	Number of claimants at end of period	5,200			8,100
	Numbers in the foregoing table are rounded to the nearest hundred and are based on information as received by us, which may lag actual court filing dates by several months or more. Claims are recorded as closed when a claimant is dismissed or severed from a case. Claims are opened whenever a new claim is brought, including from a claimant previously dismissed or severed from another case. In 2014, by virtue of a new Texas law, which amended the Texas Civil Code, the Texas courts commenced dismissing dormant asbestos cases without prejudice to re-filing by plaintiffs. In the fourth quarter of 2014, the Texas courts dismissed almost 3,000 claimants with claims against us. We expect additional dismissals in 2015.
	Our asbestos related contingent liabilities and related insurance receivables are based on an actuarial study performed by a third party, which is updated every three years. During the third quarter of 2012, we completed an actuarial study of our asbestos related contingent liabilities and related insurance receivables, which will be updated again in the third quarter of 2015. The study is based on, among other things, the incidence and nature of historical claims data through June 30, 2012, the incidence of malignancy claims, the severity of indemnity payments for malignancy and non-malignancy claims, dismissal rates by claim type, estimated future claim frequency, settlement values and reserves, and expected average insurance recovery rates by claim type. The study assumes liabilities through 2049. Overall, we expect to recover approximately 48% of our future indemnity costs. We have completed Coverage-In-Place-Agreements with most of our larger insurance carriers.
	The ultimate liability and related insurance recovery for all pending and anticipated future claims cannot be determined with certainty due to the difficulty of forecasting the numerous variables that can affect the amount of the liability and insurance recovery. These variables include but are not limited to: (i) significant changes in the number of future claims; (ii) significant changes in the average cost of resolving claims; (iii) changes in the nature of claims received; (iv) changes in the laws applicable to these claims; and (v) financial viability of co-defendants and insurers.
	Lead Pigment
	Over the past 20 years, we have been named as defendants in more than fifty cases in the U.S. in which plaintiffs assert claims for personal injury, property damage, and other claims for relief relating to one or more kinds of lead pigment that were used as an ingredient decades ago in architectural paint. Eight lead ingestion personal injury cases remain outstanding. The different suits were brought by government entities and/or individual plaintiffs, on behalf of themselves and others. The suits variously sought compensatory and punitive damages and/or injunctive relief, including funds for the cost of monitoring, detecting and removing lead based paint from buildings and for medical monitoring; for personal injuries allegedly caused by ingestion of lead based paint; and plaintiffs’ attorneys’ fees. We settled one of these cases in 2005 for an immaterial amount in order to avoid litigation costs. In all of the others, we prevailed in court or were dismissed as a defendant.
	We currently are one of several defendants in eight personal injury lead ingestion cases, consisting of 172 plaintiffs venued in federal and state courts in Milwaukee, Wisconsin. One of the eight cases, which is venued in Federal District Court in Milwaukee, consists of 164 claimants, each alleging personal injury as a result of the ingestion of white lead carbonate in paint. The remaining seven cases consist of less than 10 total plaintiffs. We believe that the eight personal injury cases against us are without merit.
	In July 2005, in a case in which we were one of several defendants, the Supreme Court of Wisconsin held that Wisconsin’s risk contribution doctrine applies to bodily injury cases against manufacturers of white lead pigment. Under this doctrine, manufacturers of white lead pigment may be liable for injuries caused by white lead pigment based on their past market shares, unless they can prove they are not responsible for the white lead pigment which caused the injury in question. Seven of the eight personal injury cases, including the personal injury case consisting of 164 plaintiffs, were filed before January 2011, when the Wisconsin legislature passed legislation that will make it substantially more difficult to bring lead suits in the future, including a 25 year statute of repose. In June 2013, the Governor of Wisconsin signed into law the biennial budget, which contained within it a provision that retroactively applies the 2011 law to all claims of lead poisoning whether filed or accrued.
	The defendants, including the Company, moved to dismiss the personal injury lead cases pending in Wisconsin state court pursuant to the new law. By decision dated March 2014 in the Wisconsin state court case styled Clark et al. v. American Cyanamid Company et al., the court denied the defendants’ motion holding unconstitutional the retroactive application of the new law. The defendants, including the Company, petitioned for leave to appeal the trial court’s decision. The petition for leave was granted by the Wisconsin Appellate Division.
	Also, in 2010, the United States District Court for the Eastern District of Wisconsin held that the risk contribution theory imposed by the Wisconsin Supreme Court for lead pigment violates the due process clause set forth in the 14th Amendment to the United States Constitution. The Court’s decision was appealed to the United States Circuit Court of Appeals for the Seventh Circuit. The Seventh Circuit Court of Appeals also requested that the parties brief the constitutionality of the new retroactivity provision in the biennial budget. In the third quarter of 2014, the United States Court of Appeals for the Seventh Circuit reversed the trial court’s dismissal and held that the risk contribution theory imposed by the Wisconsin Supreme Court for lead pigment is permissible under the United States Constitution. The Court also held that the retroactivity provision of Wis. State 845.046 is unconstitutional as it effects a vested right. Some defendants, including the Company, have petitioned the United States Supreme Court for review of the Seventh Circuit’s decision. As a result of the Seventh Circuit’s decision, the lead ingestion cases venued in the United States District Court of Wisconsin will proceed.
	Finally, in July 2009, the Wisconsin Supreme Court, in the case styled Ruben Godoy et al v. E.I. DuPont de Nemours et al., upheld a lower court’s decision dismissing the plaintiff’s strict liability and negligent defect causes of action for white lead carbonate. The decision in these cases, the new statutory law in Wisconsin, and our non-existent or diminutive market share, reinforces our belief that we have no liability in any of the eight Wisconsin cases, and accordingly, we have not recorded a loss contingency.
	Other
	Periodically, we enter into settlement discussions for lawsuits or claims for which we have meritorious defenses and for which an unfavorable outcome against us is not probable. In such instances, no loss contingency is recorded since a loss is not probable and it is our policy to expense defense costs as incurred. Typically, we consider these types of settlements in fairly limited circumstances usually related to the avoidance of future defense costs and/or the elimination of any risk of an unfavorable outcome. Such settlements, if any, are recorded when it is probable a liability has been incurred, typically upon entering into a settlement agreement.
	While it is not feasible to predict the outcome of all pending environmental matters, lawsuits and claims, it is reasonably possible that there will be a necessity for future provisions for costs for environmental matters and for other contingent liabilities that we believe, will not have a material adverse effect on our consolidated financial position, but could be material to our consolidated results of operations or cash flows in any one accounting period. We cannot estimate any additional amount of loss or range of loss in excess of the recorded amounts. Moreover, many of these liabilities are paid over an extended period, and the timing of such payments cannot be predicted with any certainty.
	From time to time, we are also included in legal proceedings as a plaintiff involving tax, contract, patent protection, environmental and other legal matters. Gain contingencies related to these matters, if any, are recorded when they are realized.
	Accounting for Uncertainty in Income Taxes
	We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon effective settlement. See Note 13 for additional information.
	Commitments
	Rental commitments
	Rental expense under property and equipment leases was $9.6 in 2014, $8.3 in 2013, and $10.9 in 2012. Estimated future minimum rental expenses under property and equipment leases that have initial or remaining noncancelable lease terms in excess of one year as of December 31, 2014 are:
	Year	Operating				Capital		Total
		Leases				Lease		Leases
	2015	$	10.1			$	3	$	13.1
	2016	8.2				3.1		11.3

	2018	2.9				2.5		5.4
2019	2				—		2
Thereafter	13.3				—		13.3
Total minimum lease payments	$	42.9			$	11.9	$	54.8
Capital lease
In conjunction with the recognition of the loss on sale of the Stamford facility in the fourth quarter of 2012 discussed in Note 3, we recorded the lease as a capital lease asset and obligation as of December 31, 2012 in the amount of $7.6, excluding executory costs.
Customer-related and purchase commitments
We frequently enter into long-term contracts with customers with terms that vary depending on specific industry practices. The business of Cytec Industries and its consolidated subsidiaries as a whole is not substantially dependent on any single contract or any series of related contracts. Set forth below are more specific terms about our significant sales contracts.
The Aerospace Materials segment is party to a number of long-term supply and pricing agreements that cover various time periods. Included are several contracts with terms of 5 years or more, which obligate us to sell and, subject to certain exceptions, obligate the respective customers to purchase their requirements of various specialty materials for products related to certain aircraft programs. Such agreements are common practice in the aerospace and aircraft manufacturing industries.
We frequently enter into long-term agreements in order to lock in prices and availability of raw materials, equipment, supplies, and services required to operate our businesses. At December 31, 2014, obligations under such agreements totaled $45.4, of which $37.0 are expected to be paid in 2015.
Other commitments
We had $15.0 of outstanding letters of credit, surety bonds, and bank guarantees at December 31, 2014 that are issued on our behalf in the ordinary course of business to support certain of our performance obligations and commitments. The instruments are typically renewed on an annual basis.

	U.S. and non-U.S. earnings of consolidated companies, before income taxes, include all earnings derived from operations in the respective U.S. and non-U.S. geographic areas; whereas provisions (benefits) for income taxes include all income taxes payable to (receivable from) U.S. Federal, non-U.S. and other governments as applicable, regardless of the sites in which the taxable income (loss) is generated.
	We operate on a global basis with manufacturing and research facilities in 11 countries coupled with our affiliates in other jurisdictions serving in various other capacities in support of the global organization. The income before income tax attributable to non-U.S. jurisdictions where the income tax rate was lower than the U.S. statutory rate for the years ended December 31, 2014 and 2013 was $117.0 and $73.8 respectively. Such jurisdictions and their corresponding statutory rates for the year ended December 31, 2014 primarily consisted of Canada (25.1%), UK (21.5%), Mexico (30.0%), Germany (28.0%), Chile (21.0%), Australia (30.0%), Belgium (33.9%), and The Netherlands (25.0%). Differences between the statutory and effective tax rates for the above jurisdictions were not material, except for Belgium where the effective tax rate was approximately 16.0% due to the application of the notional interest deduction as provided under current tax law.
	Income taxes paid in 2014, 2013 and 2012 were $57.0, $172.9, and $71.0, respectively, and included non-U.S. taxes of $26.4, $37.5, and $37.9 in 2014, 2013 and 2012, respectively.
	The temporary differences that give rise to a significant portion of deferred tax assets and liabilities are as follows:

	Gross deferred tax liabilities	$	(184.9	)		$	(179.4	)
	Net deferred tax assets	$	36.9			$	25.6
	Accounting rules require establishing a tax liability on the unrepatriated earnings of foreign subsidiaries if it is management`s intention to no longer permanently reinvest such earnings. As a result of the sale of Coatings, management`s intentions changed with regard to a portion of the unrepatriated earnings of certain foreign subsidiaries. Therefore, included in income tax expense is $3.1 of tax expense incurred due to the repatriation of certain earnings during 2012 and a tax benefit of $1.5 recognized during 2013 primarily related to a revision of our previously accrued estimated income tax liability on the repatriation of other earnings, related to the sale of Coatings. With the exception of the unremitted earnings of those international subsidiaries that are related to the Coatings divestiture, we consider the undistributed earnings of our non-U.S. subsidiaries as of December 31, 2014, to be indefinitely reinvested outside the U.S. given the estimated future capital expansion and other funding needs attributable to these entities. Moreover, we have not, nor do we anticipate the need to, repatriate funds to the U.S. to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our U.S. debt service requirements. Accordingly, no provision has been made for U.S. income taxes or additional non-U.S. taxes on the undistributed earnings of our non-U.S. subsidiaries totaling $715.7 as of December 31, 2014. In the event of repatriation to the U.S., such earnings would be subject to U.S. income taxes in most cases. Foreign tax credits would be available to substantially reduce the amount of U.S. tax otherwise payable in future years.
	We have U.S. foreign tax credit carryforwards of $41.2 available as of December 31, 2014 to offset future U.S. tax liabilities. Such U.S. foreign tax credits will expire at various dates starting in 2015, if not utilized. We have $11.2 of state tax credits of which $8.5 will be carried forward indefinitely with the balance to expire at various dates starting in 2015, to the extent not utilized. We have U.S. capital loss carryforwards of $261.9 available as of December 31, 2014 to offset future U.S. capital gains. These capital loss carryforwards will expire in 2018, to the extent not utilized.
At December 31, 2014, we have state net operating losses totaling $122.9, which are available to offset future taxable income in the respective states. The total state carryforwards expire at various dates starting in 2015 through 2029. In addition, we have foreign net operating losses for continuing operations totaling $41.7, primarily related to our operations in Europe and India. These net operating losses are available to offset future taxable income in the respective foreign countries. Of the total foreign carryforwards, approximately $6.0 expires at various dates starting in 2017, while $35.7 can be utilized over an indefinite period.
Our long-term earnings trend makes it more likely than not that we will generate sufficient taxable income on a consolidated basis to realize our net deferred- tax assets with the exception of capital loss carryforwards, certain state net operating losses and state tax credits, and various foreign deferred tax assets. Accordingly, we have recorded a valuation allowance of $114.6 and $125.9 as of December 31, 2014 and 2013, respectively.
For 2014, the $11.3 valuation allowance activity primarily consisted of a decrease to the valuation allowance for U.S. capital losses related to a revised purchase price allocation of $10.2 on the Coatings sale, a $0.3 decrease to the valuation allowance for foreign net operating losses, and a decrease to the valuation allowance for state tax credits and other state deferred tax assets of $0.8. As of December 31, 2014, $109.5 of the valuation allowance is attributable to U.S. tax attributes and $5.1 primarily relates to foreign net operating losses and other foreign deferred tax assets. For 2013, the $104.9 valuation allowance activity primarily consisted of an increase to the valuation allowance for U.S. capital losses related to the Coatings sale of $104.9, a $2.5 increase to the valuation allowance for foreign net operating losses, and a decrease to the valuation allowance for state tax credits and other state deferred tax assets of $2.5. As of December 31, 2013, $120.4 of the valuation allowance is attributable to U.S. federal and state tax attributes and $5.5 primarily relates to foreign net operating losses and other foreign deferred tax assets.
The Tax Increase Prevention Act of 2014 (the “2014 Tax Relief Act”), as signed into law on December 19, 2014 provided one year of tax relief by retroactively reinstating to January 1, 2014 a host of expired tax incentives for businesses. These business tax incentives retroactively reinstated and extended through 2014, include, but are not limited to, the research and development credit as well as the favorable look-through treatment of payments between related controlled foreign corporations.
The American Taxpayer Relief Act of 2012 (the “2012 Tax Relief Act”), as signed into law on January 2, 2013 extended a host of expired and expiring tax incentives for businesses. These business tax incentives retroactively reinstated and extended through 2013, include, but are not limited to, the research and development credit as well as the favorable look-through treatment of payments between related controlled foreign corporations. Although this legislation reinstated these favorable tax laws retroactive to January 1, 2012, accounting rules require that the tax impact of such changes be reflected in the period the law is enacted.
We are subject to income tax in many U.S. and international jurisdictions, and a certain degree of estimation is required in recording the assets and liabilities with respect to income taxes. All of our tax positions are subject to audit by the local taxing authorities in each tax jurisdiction. These tax audits can involve complex issues, interpretations and judgments and the resolution of matters may span multiple years, particularly if subject to negotiation or litigation.
We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon settlement with the tax authorities.
The amount of gross unrecognized tax benefits at December 31, 2014 is $10.0 (excluding interest), of which $9.6 would impact our effective tax rate, if recognized. As of December 31, 2013, the amount of gross unrecognized tax benefits for continuing operations is $16.7 (excluding interest), of which $15.4 would impact our effective tax rate, if recognized.
We recognize interest and penalties related to unrecognized tax benefits in income tax expense in the consolidated statements of income. We had recorded a liability for the payment of interest and penalties (gross), of approximately $1.7 as of January 1, 2014, decreasing by current year net activity of $0.5, thus resulting in a liability for the payment of interest and penalties of $1.2 as of December 31, 2014.
Set forth below is the tabular roll-forward of our 2014 and 2013 unrecognized tax benefits from uncertain tax positions:
	2014				2013
Balance as of beginning of the year:	$	16.7			$	19.7
Increase due to Umeco Acquisition	—				0.8
Increase due to tax positions related to current periods	0.8				2.9
Increase due to tax positions related to prior periods	0.5				0.9
Decrease due to tax positions related to prior periods	(5.4		)		(3.0		)
Decrease due to lapse of Statute of Limitations	(2.2		)		(0.4		)
Settlements	(0.1		)		(3.9		)
Foreign exchange	(0.3		)		(0.3		)
Balance as of the end of the year:	$	10			$	16.7
Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Any settlements or statute of limitations expirations could likely result in a decrease in our uncertain tax positions. Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Any settlements or statute of limitations expirations could likely result in a decrease in our uncertain tax positions. We believe that it is reasonably possible that approximately $1.6 of our current unrecognized tax benefits may be recognized within the next twelve months due to the lapse of the statute of limitations in certain international jurisdictions.
The Internal Revenue Service (the “IRS”) has completed and closed its audits of our income tax returns through 2008. During the second quarter of 2013, the IRS commenced the audit of Cytec’s tax returns for the years 2009, 2010 and 2011, which is still ongoing as of December 31, 2014. During the first quarter of 2014, the IRS completed the federal income tax audit of Umeco for the tax years ended March 31, 2010, 2011 and 2012. The total net liability for the three years was approximately $0.1, and was paid in March 2014. Consequently, in the first quarter of 2014 we recorded a benefit in the consolidated statement of income for the reversal of ASC Subtopic 740-10 (FIN 48) accruals in the amount of $3.9. In the fourth quarter of 2014, the IRS initiated a limited scope income tax audit of Umeco for the tax year ended March 31, 2009, which is still ongoing as of December 31, 2014. We believe adequate provisions for all outstanding issues have been made for all open years.
State income tax returns are generally subject to examination for a period of 3-5 years after filing of the respective return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. Years still open to examination by tax authorities in major jurisdictions include: Arizona (2010 onward), California (2004 onward), Connecticut (2011 onward), Georgia (2011 onward), Louisiana (2012 onward), Maryland (2011 onward), Michigan (2010 onward), New Jersey (2011 onward), North Carolina (2011 onward), Ohio (2011 onward), South Carolina (2011 onward), Texas (2010 onward), and West Virginia (2011 onward). We have various state income tax returns in the process of examination.
International jurisdictions have statutes of limitations generally ranging from 3-5 years after filing of the respective return. Years still open to examination by tax authorities in major jurisdictions for continuing and discontinued operations include: Austria (2012 onward), Belgium (2011 onward), Germany (2008 onward), Netherlands (2008 onward), Canada (2003 onward), UK (2010 onward), Italy (2011 onward), China (2009 onward), and Norway (2010 onward). We are currently under examination in several of these jurisdictions.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS
	We have defined benefit and defined contribution pension plans that cover employees in a number of countries. We also sponsor postretirement and postemployment benefit plans in certain countries. The postretirement plans provide medical and life insurance benefits to retirees who meet minimum age and service requirements, and in the case of non-bargaining employees, who commenced employment prior to April 1, 2007. The medical plans are contributory and non-contributory with certain participants’ contributions adjusted annually; the life insurance plans are non-contributory. The accounting for the postretirement plans anticipates future cost-sharing and changes to the plans. The postretirement plans include a cap on our share of costs for recent and future retirees. The postemployment plans provide salary continuation, disability-related benefits, severance pay, and continuation of health costs during the period after employment but before retirement.
	We utilize the MTM method of accounting, under which our pension and OPEB costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; and 2) MTM gains and losses recognized annually, in the fourth quarter of each year, resulting from changes in actuarial assumptions and the differences between actual and expected returns on plan assets and discount rates. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized as an MTM adjustment in the quarter in which such remeasurement event occurs.
	We used a measurement date of December 31, 2014, 2013 and 2012 for all our pension and postretirement benefit plans.

	Rate of compensation increase	2.5%-5.0%				2.5%-5.0%				2.5%-4.5%
	The expected rate of return on U.S. plan assets was determined by examining the annualized rates of return over various five and ten year periods for the major U.S. stock and bond indexes and the estimated long-term asset mix of the plan assets of 10%-20% stocks and 80%-90% long-term bonds, including cash equivalents (“fixed income securities”). Since the long-term average annualized return is approximately 7.0%-9.0% for stocks and 4.0%-6.0% for fixed income securities, the expected long-term weighted average return was estimated to be 5.75% and 6.0% for the U.S. pension plans in 2014 and 2013, respectively. This return was based on an assumed allocation of U.S. pension assets of 20% stocks and 80% in fixed income securities for 2014 and 30% stocks and 70% fixed income securities for 2013. Expected long-term investment returns for U.S. investments were 9.0% for stocks and 4.95% for fixed income securities in 2014 and 9.0% for stocks and 4.7% for fixed income securities in 2013. For U.S. and non-U.S. postretirement plans, assets are only held in the U.S. The expected rate of return on postretirement assets was 6.0% in 2014 and 6.25% in 2013, based on an assumed asset allocation of 40% stocks and 60% fixed income securities in 2014 and 40% stocks and 60% fixed income securities in 2013.
	The investment strategy for our worldwide benefit plan assets is to maintain broadly-diversified portfolios of stocks, bonds, and money market instruments that, along with periodic plan contributions, provide the necessary liquidity for ongoing benefit obligations.
	The expected return on non-U.S. plan assets is also based on the historical rates of return of the various asset classes in each country and the corresponding asset mix. For our two largest non-U.S. pension plans, the assumed weighted average rate of return was 4.65% in 2014. The 2014 return was based on assumed weighted average rates of return of 5.5% for stocks and 4.0% for fixed income securities and an assumed weighted average asset allocation of 43% stocks and 57% fixed income securities.

	-1	Represents various curtailments and settlements. During 2014, we had a one-time settlement of $118.3 due to the Bulk Lump Sum offering for terminated vested and divested employees who received a lump sum payout during December 2014. Also in 2014, we recognized a curtailment gain of $1.5 related to certain bargaining employees transitioning to a defined contribution plan; the impact of this curtailment was a reduction to the obligation of$2.1 and recognition of previously deferred prior service cost of $0.5. The net curtailment gain of $1.5 is included in Manufacturing cost of sales in the consolidated statements of income.
	In the second quarter of 2013, we had a curtailment gain of $7.7 related to the sale of Coatings, which is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statements of income. In the fourth quarter of 2013, we recognized a curtailment gain of $1.2 related to certain bargaining employees transitioning to a defined contribution plan.
	During 2012, we had a curtailment loss of $0.7 associated primarily with the pending sale of Coatings, which is included in Earnings from operations of discontinued business, net of tax in the consolidated statements of income.
	The postretirement plan benefit obligation includes Medicare Part D subsidies received that reduce company contributions. The amounts received for 2014, 2013 and 2012 were $0.0, $0.0, and $0.7, respectively.

The total fair value of U.S. pension and postretirement plan assets was $771.7 and $809.8 at December 31, 2014 and 2013, respectively. We had previously invested certain U.S. pension assets directly in our common stock, which were sold during 2013. We use a combination of active and passive stock and bond managers to invest all assets of the pension and postretirement plans. The managers are selected based on an analysis of, among other things, their historical investment results, frequency of management turnover, cost structure, and assets under management. Assets are periodically reallocated among the investment managers to maintain the appropriate asset mix and are occasionally transferred to new or existing managers in the event that a manager is terminated.
Our overall investment strategy is to achieve a mix of approximately 95% of investments for long-term growth and 5% for near-term benefit payments with a wide diversification of asset types, fund strategies, and fund managers. The target allocations for U.S. pension plan assets are 10% equity securities and 90% corporate bonds and U.S. Treasury securities. The target allocations for postretirement plan assets are 40% equity securities and 60% corporate bonds and U.S. Treasury securities. Equity securities primarily include investments in large-cap, mid-cap and small-cap companies primarily located in the United States. Fixed income securities include corporate bonds of companies from diversified industries, mortgage-backed securities, and U.S. Treasuries. In order to reduce the volatility of our pension plan assets relative to pension liabilities, over the past two and a half years we have gradually implemented a liability-driven investment strategy for our U.S., U.K. and Canadian defined benefit pension plans. As part of the strategy, we have transitioned some of our equity allocation to longer-term fixed income assets.
The target allocations for non-U.S. plan assets are 30-50% equity securities, 40-60% corporate bonds and government securities, and 0-15% all other types of investments. Equity securities primarily include a broadly diversified portfolio of common stocks of publicly traded companies that are primarily non-U.S. Fixed income securities include corporate bonds, mortgage-backed securities, and government bonds. Other types of investments include cash, insurance assets, and real estate.
The fair values of our Level 1 pension assets are determined based on quoted market prices in active markets for identical assets. The fair values of our Level 2 pension assets are based on the net asset values of the funds, which are based on quoted market prices of the underlying investments. Our Level 3 assets primarily include an insurance contract and a real estate fund. The fair values of the insurance contract held by one of our non-U.S. plans are based on the contractual terms of the arrangement with the insurance company. The fair value of the real estate fund is based on the net asset value of shares held at year end.
The fair values of the pension assets at December 31, 2014 and 2013, by asset category, are as follows:

We also sponsor various defined contribution retirement plans in a number of countries, consisting primarily of savings, profit growth, and profit sharing plans. Contributions to the savings plans are based on matching a percentage of employees’ contributions. Contributions to the profit growth and profit sharing plans are generally based on our financial performance.
Amounts expensed related to these plans are as follows:
Years ended December 31,	2014				2013				2012

Others	$	4.2			$	3.7			$	2.9
In addition to defined benefit pension and postretirement plans and defined contribution retirement plans, we also sponsor immaterial postemployment plans in a number of countries. Those plans, in certain circumstances, provide salary continuation, disability related benefits, severance pay and continuation of health care coverage during the period after employment but before retirement.
Certain of our benefit plans provide for enhanced benefits in the event of a “change of control” as defined in the plans.
Bulk lump sum offer
In September 2014, we commenced a voluntary bulk lump sum (“BLS”) offer program. We offered approximately 3,000 eligible terminated vested and divested employees under the pension plan a voluntary single lump sum payment option in lieu of a future pension benefit. The payouts to the BLS eligible former employees were funded by assets of the pension plan, and most were paid prior to December 31, 2014. The BLS program is part of our pension de-risking strategy and is expected to reduce volatility prospectively and lessen the administrative burden.

	We have four reportable business segments: Aerospace Materials, Industrial Materials, In Process Separation, and Additive Technologies. The Aerospace Materials segment principally includes advanced composites, carbon fiber, and structural film adhesives. The Industrial Materials segment includes structural composite materials (high performance automotive, motorsports, recreation, tooling and other structural materials markets) and process materials (aerospace, wind energy, and other process materials markets). The In Process Separation segment includes mining chemicals and phosphines. The Additive Technologies segment includes polymer additives, specialty additives, and formulated resins.
	The accounting policies of the reportable segments are the same as those described in Note 1. All intersegment sales prices are cost based. We evaluate the performance of our operating segments primarily based on earnings from operations of the respective segment. As described in Note 4, restructuring costs and impairment charges related to unprofitable sites are not charged to our operating segments consistent with management’s view of its businesses.
	As discussed in Note 3, the former Coatings business is reported as discontinued operations for all periods presented.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Nature of Business	We are a global specialty materials and chemicals company focused on developing, manufacturing and selling value-added products. Our products serve a diverse range of end markets including aerospace and industrial materials, mining and plastics. We use our technology and application development expertise to create chemical and material solutions that are formulated to perform specific and important functions for our customers. We operate on a global basis with 48% of our 2014 revenues in North America, 31% in Europe, Middle East, and Africa, 12% in Asia-Pacific, and 9% in Latin America. We have manufacturing and research facilities located in 11 countries.
Consolidation Policy	The consolidated financial statements include the accounts of Cytec Industries Inc. and our subsidiaries on a consolidated basis. The footnotes relate to continuing operations except where noted otherwise. Intercompany transactions and balances have been eliminated. The equity method of accounting is used for investments in associated companies that we do not control, but for which we have the ability to exercise significant influence on operating and financial policy.
Inventories	Inventories: Inventories are stated at the lower of cost or market. We determine cost using the first-in, first-out method.
Currency Translation	Currency Translation: Operations in our international subsidiaries are recorded in local currencies, which are also the functional currencies for financial reporting purposes. The results of operations for our international subsidiaries are translated from local currencies into U.S. dollars (“USD”) using the average currency rate during each period which approximates the results that would be obtained using actual currency rates on the dates of individual transactions. Assets and liabilities are translated using currency rates at the end of the period with translation adjustments recorded in accumulated translation adjustments and recognized as a component of accumulated other comprehensive income (“OCI”). Gains and losses on foreign currency transactions, which represent the translation of transactions denominated in currencies other than the functional currency of the impacted legal entity, are recorded as incurred in Other (expense) income, net.
Depreciation	Depreciation: Depreciation is provided on a straight-line basis over the estimated useful lives of the assets. When these assets are retired or disposed of, the net book value of assets are removed from the consolidated balance sheet and the net gain or loss is included in the determination of earnings from operations.
	Expenditures for maintenance and repairs are charged to current operating expenses. Acquisitions, additions, and betterments, either to provide necessary capacity, improve the efficiency of production units, modernize or replace older facilities, or to install equipment for protection of the environment, are capitalized. We capitalize interest costs incurred during the period of construction of plants and equipment.
Impairment or Disposal of Long-Lived Assets	Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of: Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets and would be charged to income. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the costs to sell.
Goodwill and Intangible Assets	Goodwill and Intangible Assets: We have defined our reportable segments as our reporting units for our goodwill accounting. We test goodwill for impairment on an annual basis as of October 1st and more often if events occur or circumstances change that would likely reduce the fair value of a reporting unit to an amount below its carrying value. When necessary, we record charges for goodwill impairments for the amount by which the implied fair value of goodwill is less than its carrying value.
	We test our goodwill using either a qualitative or quantitative approach. Under the qualitative approach for a goodwill impairment test, we first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (i.e. – greater than 50% probability) that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of the facts and circumstances, we determine it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then performing the two-step impairment test, described below, is unnecessary. If we determined otherwise, we would be required to perform the two-step goodwill impairment test. For our qualitative assessment of the reporting unit, we consider all relevant facts and circumstances, including the excess fair value from the most recent fair value calculation; circumstances that could cause significant changes to the most recent carrying value calculation; the overall financial performance of the reporting unit compared to previous projections; the estimated financial performance projected in the near and long term, such as Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and cash flows; industry and market conditions, including overall market-multiple metrics, competitive environment and demand for our products; overall macroeconomic conditions including our ability to access capital; and changes in management, key personnel or strategy for the reporting unit. More weight is placed on events or circumstances that most affect a reporting unit’s fair value or carrying amount of its net assets.
	If we decide to or are required to perform the two-step goodwill impairment test, we begin by comparing the reporting unit’s fair value to its carrying value. We initially use a market multiple approach (1A) to estimate a range of fair values by reporting unit, and then use a discounted cash flow approach (1B) if the market multiple approach indicates that a potential impairment might exist to refine and reaffirm the results of the first test. Due to the cyclical nature of our reporting units, market multiple values are determined utilizing a three-year average of EBITDA. The three-year period is comprised of the prior year, current year, and one year of projected amounts. If the reporting unit’s estimated fair value at the low end of the range is close to, in our judgment, or below the reporting unit’s carrying value, we refine the calculation using discounted cash flows to calculate a point estimate of the reporting unit’s fair value, as opposed to a range. If the discounted cash flow approach yields a fair value estimate less than the reporting unit’s carrying value, we would proceed to step two of the impairment test, which is used to measure the amount of the impairment loss. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The resulting implied fair value of the goodwill that results from the application of this second step would then be compared to the carrying amount of the goodwill and an impairment charge would be recorded for the difference.
	Intangible assets are amortized on a straight-line basis over their respective estimated useful lives. Intangible assets with determinable useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets and would be charged to income.
Cash and Cash Equivalents	Cash and Cash Equivalents: Securities with maturities of three months or less when purchased are considered to be cash equivalents.
Financial Instruments	Financial Instruments: Certain financial instruments are recorded at cost, which approximates fair value such as cash and cash equivalents, receivables, certain other assets, accounts payable, and certain other liabilities. Fair values are determined through a combination of management estimates and information obtained from third parties using the latest available market data. Long-term debt is carried at amortized cost.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities: We use derivative instruments in accordance with our established policies to manage exposure to fluctuations in currency rates, interest rates, and, at times, certain commodity costs. We do not hold or issue derivative financial instruments for trading or speculative purposes. We enter into financial instrument transactions with either major financial institutions or highly rated counterparties and make reasonable attempts to diversify transactions among counterparties, thereby limiting exposure to credit-related and performance-related risks.
	Foreign Currency Risk: We use currency forward contracts and have used cross currency swaps to manage our exposure to fluctuations in currency rates on third party and intercompany transactions denominated in currencies other than the functional currency of the legal entity. We hedge such exposures with currency forward contracts denominated in the same currency and with similar terms as the underlying exposure, and therefore, the instruments are effective at generating offsetting changes in the fair value or cash flows of the hedged item or transaction. All derivative contracts used to manage foreign currency risk are measured at fair value and reported as assets or liabilities on the balance sheet. Following the termination of our cross currency swaps in July 2012, we have not elected to apply hedge accounting. Changes in fair value are recorded in Other (expense) income, net.
Environmental and Other Contingent Liabilities	Environmental and Other Contingent Liabilities: Accruals for environmental remediation, maintenance, and operating costs directly related to remediation, and other contingent liabilities are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Accruals for environmental liabilities and other contingent liabilities are recorded as Other noncurrent liabilities with amounts expected to be paid out in the next twelve months classified as Accrued expenses at undiscounted amounts.
Insurance/Self-Insurance	Insurance/Self-Insurance: It is our practice to conduct an analysis of our self-insured and insured contingent liabilities annually and whenever circumstances change significantly. Included in these liabilities are workers’ compensation, product liability, and toxic tort claims.
	Probable insurance recoveries for past and future indemnity costs are recorded in other receivables, to the extent collection is reasonably assured within the next twelve months, and longer term receivables are included in other assets at our best estimate of the ultimate expected receipts at undiscounted amounts. Defense and processing costs are expensed as incurred. Probable insurance recoveries for defense and processing costs are recognized only as actual costs are incurred.
Asset Retirement Obligations	Asset Retirement Obligations: We recognize the fair value of the liability for an asset retirement obligation in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. The liability is accreted at the end of each period through charges to operating expense. If the obligation is settled for other than the carrying amount of the liability, we recognize a gain or loss on settlement.
Income Taxes	Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. If repatriation of the undistributed income of our international subsidiaries and associated companies is anticipated then income taxes are provided for such earnings. The undistributed earnings of all other foreign subsidiaries will be indefinitely reinvested in their operations.
	We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon settlement with the tax authorities. We recognize interest and penalties related to unrecognized tax benefits in income tax expense in the consolidated statements of income.
Postretirement Benefits	Postretirement Benefits: Costs of postretirement benefits are recognized as employees render the services necessary to earn the related benefits. We recognize an asset or liability for the overfunded or underfunded status of postretirement plans that we sponsor. We measure plan assets and benefit obligations as of the date of the employer’s statement of financial position.
	We utilize the mark-to-market (“MTM”) method of accounting, under which our pension and other postemployment benefit (“OPEB”) costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; and 2) MTM gains and losses recognized annually, in the fourth quarter of each year, resulting from changes in actuarial assumptions and the differences between actual and expected returns on plan assets and discount rates. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized as an MTM adjustment in the quarter in which such remeasurement event occurs. For additional information, see Note 14, “Employee Benefit Plans.”
Revenue Recognition	Revenue Recognition: We recognize revenue when persuasive evidence of an arrangement exists, the selling price is fixed or determinable, collection is reasonably assured, and title and risk of loss has passed to our customers. Customer rebates are estimated and recognized as a reduction of sales as such rebates are being earned.
Stock-Based Compensation	Share-Based Compensation: We recognize our share-based compensation cost in an amount equal to the fair value of share-based payments and estimate a forfeiture rate for all share-based awards. We monitor share option exercise and employee termination patterns to estimate forfeiture rates within the valuation model.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions. These estimates or assumptions affect the reported amounts and disclosures. For example, estimates are used when accounting for allowance for doubtful accounts, inventory valuations, useful lives of tangible and intangible assets, recoverability of goodwill, accrued expenses, environmental and other contingent liabilities, pension and other postretirement benefits, income tax valuation allowances and assumptions utilized in determining share-based compensation. Actual results could differ from these estimates. Accounting estimates require the use of judgment regarding uncertain future events and their related effects and, accordingly, may change as additional information is obtained.
New Accounting Pronouncements Not Yet Adopted	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which will supersede current revenue recognition guidance in Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition.” The new standard is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions previously not addressed comprehensively, and clarify guidance for multiple-element arrangements. This new standard is effective for the first quarter of 2017 using one of two prescribed transition methods. We have not yet selected a transition method and continue to evaluate the impact this guidance will have on our future consolidated results of operations, financial condition, and related disclosures.
New Accounting Pronouncements Adopted	In February 2013, the FASB issued ASU No. 2013-02. This ASU required us to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income–but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. It also required us to cross-reference to other disclosures currently required under U.S. GAAP for other reclassification items (that are not required under U.S. GAAP to be reclassified directly to net income in their entirety in the same reporting period). On January 1, 2013, we adopted the provisions of ASU No. 2013-02, which are reflected in these financial statements.
Reclassifications	Reclassifications: Certain amounts, including changes in our equity structure, reported for prior years in the Consolidated Financial Statements and Notes to Consolidated Financial Statements have been reclassified to conform to the current year’s presentation.
	Except for the number of authorized shares and par value, all references to shares and per share data for all periods presented herein reflect the impact of the 2-for-1 stock split in the form of a stock dividend, which was effective in September 2014 (the “September 2014 stock split”). See Note 17 for additional information related to this stock split.
	In the consolidated statement of cash flows for the year ended December 31, 2013, we have corrected certain immaterial prior period misclassifications, which related to changes in accounts payable related to certain capital projects. These corrections resulted in a $4.9 increase to net cash provided by operating activities of continuing operations, and a $4.9 increase to net cash used in investing activities of continuing operations. The corrections did not impact our consolidated statement of income for the year ended December 31, 2013 or consolidated balance sheet as of December 31, 2013.
Earnings Per Share, Policy	Basic earnings per common share excludes dilution and is computed by dividing net earnings available to common stockholders by the weighted-average number of common shares outstanding (which includes shares outstanding, less performance and nonvested shares for which vesting criteria have not been met) plus deferred stock awards, weighted for the period outstanding. Diluted earnings per common share is computed by dividing net earnings available to common stockholders by the sum of the weighted-average number of common shares outstanding for the period adjusted (i.e., increased) for all additional common shares that would have been outstanding if potentially dilutive common shares had been issued and any proceeds of the issuance had been used to repurchase common stock at the average market price during the period. Under this method, an increase in the fair market value of the Company’s stock can result in a greater dilutive effect from potentially dilutive common shares. The proceeds are assumed to be the sum of the amount to be paid to the Company upon exercise of options, the amount of compensation cost attributed to future services and not yet recognized, and the amount of income taxes that would be credited to or deducted from capital upon exercise.

Also in 2014, we recognized a curtailment gain of $1.5 related to certain bargaining employees transitioning to a defined contribution plan; the impact of this curtailment was a reduction to the obligation of$2.1 and recognition of previously deferred prior service cost of $0.5. The net curtailment gain of $1.5 is included in Manufacturing cost of sales in the consolidated statements of income.
	In the second quarter of 2013, we had a curtailment gain of $7.7 related to the sale of Coatings, which is included in Net gain (loss) on sale of discontinued operations, net of tax in the consolidated statements of income. In the fourth quarter of 2013, we recognized a curtailment gain of $1.2 related to certain bargaining employees transitioning to a defined contribution plan.
	During 2012, we had a curtailment loss of $0.7 associated primarily with the pending sale of Coatings, which is included in Earnings from operations of discontinued business, net of tax in the consolidated statements of income.
