Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND OPERATIONS	ORGANIZATION AND OPERATIONS:
	The accompanying Consolidated Financial Statements of RTI International Metals, Inc. and its subsidiaries (the “Company” or “RTI”) include the financial position and results of operations for the Company.
	The Company is a leading producer and global supplier of titanium mill products and a manufacturer of fabricated titanium and specialty metal components for the international aerospace, defense, energy, medical device, and other consumer and industrial markets. It is a successor to entities that have been operating in the titanium industry since 1951. The Company first became publicly traded on the New York Stock Exchange in 1990 under the name RMI Titanium Co. and the symbol “RTI,” and was reorganized into a holding company structure in 1998 under the name RTI International Metals, Inc.
	On April 25, 2014, following shareholder approval at the Company's 2014 Annual Meeting of Shareholders (the "Annual Meeting"), the Company filed a Certificate of amendment with the Ohio Secretary of State which amended the Company's Amended and Restated Articles of Incorporation by (1) increasing the number of the Company's authorized common shares from 50,000,000 to 100,000,000 and (2) deleting the previously authorized but unissued Series A Junior Participating Preferred Stock.
	On January 22, 2014, the Company acquired all of the issued and outstanding common stock of Directed Manufacturing, Inc. (now known as “RTI Directed Manufacturing”). RTI Directed Manufacturing additively manufactures plastic and specialty metal components using 3-D printing technology for a variety of markets, including the commercial aerospace, medical, and oil and gas markets. The acquisition provides potential solutions for the Company’s customers who seek near-net shape titanium and other specialty metal parts and components.
	On June 3, 2014, the Company acquired all of the issued and outstanding common stock of Dynamet Technology, Inc. (now known as "RTI Advanced Powder Materials"). RTI Advanced Powder Materials is an industry innovator in titanium powder metallurgy and a supplier of near-net shape titanium and titanium alloy preforms and components to commercial aerospace, defense, biomedical, and industrial customers. Subsequent to its acquisition, RTI Advanced Powder Materials was merged with and into RMI Titanium Company, which is part of the Titanium Segment.
	In February 2014, the Company completed its efforts to dispose of its non-core service centers Pierce Spafford Metals Company, Inc. ("RTI Pierce Spafford") and Bow Steel Corporation (“RTI Connecticut”). The results of RTI Pierce Spafford and RTI Connecticut have been presented as results from discontinued operations on the Company’s Consolidated Statements of Operations and the related assets and liabilities have been presented separately on the Company’s Consolidated Balance Sheets as assets and liabilities of discontinued operations. The Company’s Consolidated Financial Statements and the Notes thereto have been conformed to exclude amounts attributable to the aforementioned discontinued operations.
	The Company conducts business in two segments: the Titanium Segment and the Engineered Products and Services (“EP&S”) Segment.
	The Titanium Segment melts, processes, produces, forges, stocks, distributes, finishes, cuts-to-size, and facilitates just-in-time delivery services of a complete range of titanium mill products which are further processed by its customers for use in a variety of commercial aerospace, defense, and industrial and consumer applications. With operations in Niles and Canton, Ohio; Martinsville, Virginia; Norwalk, California; Burlington, Massachusetts; Tamworth, England; and Rosny-Sur-Seine, France, the Titanium Segment has overall responsibility for the production and distribution of primary mill products including, but not limited to bloom, billet, sheet, and plate. In addition, the Titanium Segment produces ferro titanium alloys for its steelmaking customers. The Titanium Segment also focuses on the research and development of evolving technologies relating to raw materials, melting, and other production processes, and the application of titanium in new markets.
	The EP&S Segment is comprised of companies with significant hard and soft-metal expertise that form, extrude, fabricate, additively manufacture, machine, micro machine, and assemble titanium, aluminum, and other specialty metal parts and components. Its products, many of which are complex engineered parts and assemblies, serve the commercial aerospace, defense, medical device, oil and gas, power generation, and chemical process industries, as well as a number of other industrial and consumer markets. With operations located in Minneapolis, Minnesota; Houston, Austin, and Spring, Texas; Sullivan and Washington, Missouri; Laval, Canada; and Welwyn Garden City and Bradford, England, the EP&S Segment provides value-added products and services such as engineered tubulars and extrusions, fabricated and machined components and subassemblies, and components for the production of minimally invasive and implantable medical devices, as well as engineered systems for deepwater oil and gas exploration and production infrastructure. The EP&S Segment utilizes the Titanium Segment as its primary source of titanium mill products.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS:
	In conjunction with the reorganization of its reportable segments in 2013, the Company evaluated its long-term growth strategy and determined it would sell or seek other strategic alternatives for its non-core service centers, RTI Connecticut and RTI Pierce Spafford. In February 2014, the Company completed the sale of the assets of RTI Connecticut for approximately $3.3 million in cash. In April 2013, the Company completed the sale of its RTI Pierce Spafford subsidiary for approximately $12.4 million in cash, of which $1.9 million was received at the expiration of the escrow period in 2014.
	The results of RTI Connecticut and RTI Pierce Spafford, including all fair value adjustments and losses on the completed sale, have been presented as results from discontinued operations. The related assets and liabilities have been presented separately on the Company’s Consolidated Balance Sheets as assets and liabilities of discontinued operations. The results of RTI Connecticut were previously reported in the Titanium Segment, while the results of RTI Pierce Spafford were reported in the Titanium Group, prior to the segment reorganization in 2013.
	The Company’s results from discontinued operations are summarized below:
		Year Ended December 31,

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
	Principles of consolidation:
	The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), and include the accounts of RTI International Metals, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to current year presentation.
	Use of estimates:
	U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at year-end and the reported amounts of revenues and expenses during the year. Actual results could differ from these estimates. Significant items subject to such estimates and assumptions include the carrying values of accounts receivable, inventories, property, plant, and equipment, intangible assets, goodwill, pensions, post-retirement benefits, worker’s compensation, environmental liabilities, and income taxes.
	Fair value:
	For certain of the Company’s financial instruments and account groupings, including cash, short-term investments, accounts receivable, accounts payable, accrued wages and other employee costs, unearned revenue, and other accrued liabilities, the carrying value of the instruments and account groupings approximates fair value.
	The Financial Accounting Standards Board (the “FASB”) defines fair value as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy prioritizes the inputs utilized in measuring fair value as follows:
	•	Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date;
	•	Level 2—inputs other than the quoted prices in active markets that are observable for the asset or liability, either directly or indirectly; and
	•	Level 3—unobservable inputs for the asset or liability.
	The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including its short-term investments and marketable securities.
	Listed below are the Company's assets and liabilities, and their respective fair values, which were measured at fair value on a recurring basis as of December 31, 2014. The Company uses trading prices at the balance sheet date to determine the fair value of its assets measured on a recurring basis. The fair value of contingent consideration payable that was classified as Level 3 relates to probability assessments of expected future revenues related to the RTI Advanced Powder Materials acquisition. The contingent consideration is to be paid over the next ten years, and there is no limit to the potential amount of contingent consideration. The Company held no assets or liabilities measured at fair value on a recurring basis as of December 31, 2013. There were no transfers between levels during the year ended December 31, 2014.
			Quoted Market Prices			Significant Other Observable Inputs			Significant Unobservable Inputs			Fair Value

	The fair value of contingent consideration was determined using a discounted cash flow model using a discount rate of 13.0%.
	As of both December 31, 2014 and 2013, the Company did not have any financial assets or liabilities that were measured at fair value on a non-recurring basis. Refer to discussions of intangible assets below for nonfinancial assets measured at fair value on a non-recurring basis.
	The carrying amounts and fair values of financial instruments for which the fair value option was not elected were as follows:
			31-Dec-14						31-Dec-13
			Carrying Amount			Fair Value			Carrying Amount			Fair Value
	Cash and cash equivalents		$	182,059		$	182,059		$	343,637		$	343,637
	Current portion of long-term debt		$	111,645		$	119,522		$	1,914		$	1,914
	Long-term debt		$	345,012		$	405,886		$	430,300		$	559,986
	The fair value of the current portion of long-term debt includes the $114,381 principal outstanding on the Company's 3.00% Convertible Senior Notes due 2015 (the “2015 Notes”). The fair value of long-term debt includes $402,500 aggregate principal amount 1.625% Convertible Senior Notes due 2019 (the “2019 Notes”) and is inclusive of the conversion feature, which was originally allocated for reporting purposes at $122.5 million, and is included in the Consolidated Balance Sheets within additional paid-in capital. The fair value of long-term debt was estimated based on significant observable inputs, including recent trades and trading levels of the outstanding debt on December 31, 2014 and 2013 (Level 2).
	Cash, cash equivalents and short-term investments:
	Cash and cash equivalents
	The Company considers all highly-liquid investments with an original maturity of three months or less to be cash equivalents. Cash equivalents principally consist of investments in short-term money market funds and corporate commercial paper.
	Available-for-sale securities
	Investments with maturities of less than one year are classified as available-for-sale, short-term investments and are recorded at fair value based on market quotes using the specific identification method, with unrealized gains and losses recorded as a component of accumulated other comprehensive loss until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identifications basis. The Company considers these investments to be available-for-sale as they may be sold to fund other investment opportunities as they arise.
	The major categories of the Company's cash equivalents and available-for-sale, short-term investments are as follows:
	Commercial paper
	The Company invests in high-quality commercial paper issued by highly-rated corporations and governments. By definition, the stated maturity on commercial paper obligations cannot exceed 270 days.
	Money market mutual funds
	The Company invests in money market mutual funds that seek to maintain a stable net asset value of $1.00, while limiting overall exposure to credit, market, and liquidity risks.
	Cash, cash equivalents, and short-term investments consisted of the following:
			December 31,			December 31,
			2014			2013
	Cash and cash equivalents:
	Cash		$	73,495		$	62,394
	Cash equivalents:
	Commercial paper		19,996			150,978
	Money market mutual funds		88,568			130,265
	Total cash and cash equivalents		182,059			343,637
	Short-term investments:
	Commercial paper		148,383			—
	Total short-term investments		148,383			—
	Total cash, cash equivalents, and short-term investments		$	330,442		$	343,637
	The Company had no short- or long-term investments at December 31, 2013. The Company's short-term investments at December 31, 2014 were as follows:
						Gross Unrealized
			Amortized Cost			Gains			Losses			Fair Value
	Commercial paper		$	148,447		$	—		$	64		$	148,383
	Total		$	148,447		$	—		$	64		$	148,383
	The Company typically purchases its available-for-sale debt securities either at a premium or a discount. The premium or discount is amortized over the remaining term of each security using the effective interest method. Amortization is recorded as either a decrement to interest income for premiums or an increment to interest income for discounts. For the year ended December 31, 2014, net amortization of premiums and discounts was immaterial.
	The Company classifies investments maturing within one year as short-term investments. Investments maturing in excess of one year are classified as noncurrent. All of the Company's investments had contractual maturities of less than one year at December 31, 2014.
	As of December 31, 2014, no investments classified as available-for-sale had been in a continuous unrealized loss position for greater than twelve months. The Company believes that the unrealized losses on the available-for-sale portfolio as of December 31, 2014 are temporary in nature and are related to market interest rate fluctuations and not indicative of a deterioration in the creditworthiness of the issuers.
	Receivables:
	Receivables are carried at net realizable value. Estimates are made as to the Company’s ability to collect outstanding receivables, taking into consideration the amount, the customer’s financial condition, and the age of the debt. The Company ascertains the net realizable value of amounts owed and provides an allowance when collection becomes doubtful. Receivables are expected to be collected in the normal course of business and consisted of the following:
			December 31,
		2014			2013
Trade and commercial customers		$	118,439		$	106,091
Less: Allowance for doubtful accounts		(694		)	(820		)
Total receivables		$	117,745		$	105,271
Inventories:
Inventories are valued at cost as determined by the last-in, first-out (“LIFO”) method for approximately 55% and 56%, respectively, of the Company’s inventories as of December 31, 2014 and 2013. The remaining inventories are valued at cost determined by a combination of the first-in, first-out (“FIFO”) and weighted-average cost methods. Inventory costs generally include materials, labor, and manufacturing overhead (including depreciation). When market conditions indicate an excess of carrying cost over market value, a lower-of-cost-or-market provision is recorded. There were no LIFO decrements for the years ended December 31, 2014 or 2013.
Inventories consisted of the following:
		December 31,
		2014			2013
Raw materials and supplies		$	172,214		$	166,359
Work-in-process and finished goods		332,573			314,438
LIFO reserve		(30,481		)	(50,709		)
Total inventories		$	474,306		$	430,088
Costs in excess of billings:
As of December 31, 2014 and 2013, the Company had costs in excess of billings of $5,522 and $5,377, respectively. All $5,522 of costs in excess of billings are expected to be collected within the next twelve months. The Company had no claims included in inventory or progress payments netted against inventory at December 31, 2014 or 2013, respectively.
Billings in excess of costs:
As of December 31, 2014, the Company had billings in excess of costs of $9,962. All $9,962 of billings in excess of costs are expected to be recognized as revenue within the next twelve months. The Company had no billings in excess of costs at December 31, 2013.
Other current assets:
The Company had other current assets of $19,803 and $16,947 at December 31, 2014 and 2013, respectively. Other current assets are comprised mainly of prepaid income taxes and other prepaid expenses which do not individually exceed five percent of consolidated current assets, and are expected to be realized within twelve months of the balance sheet date. The increase in other current assets in 2014 is attributable to an increase in prepaid income taxes.
Property, plant, and equipment:
The cost of property, plant, and equipment includes all direct costs of acquisition and capital improvements. Applicable amounts of interest on borrowings outstanding during the construction or acquisition period for major capital projects are capitalized. During the years ended December 31, 2014 and 2013, no interest expense was capitalized related to major capital expansion projects.
Property, plant, and equipment is stated at cost and consisted of the following:
		December 31,
		2014			2013
Land		$	18,778		$	18,769
Buildings and improvements		117,646			117,225
Machinery and equipment		471,691			446,787
Computer hardware and software, furniture and fixtures, and other		70,378			65,622
Construction-in-progress		53,566			52,546
		732,059			700,949
Less: Accumulated depreciation		(362,772		)	(328,609		)
Total property, plant, and equipment, net		$	369,287		$	372,340
Depreciation is determined using the straight-line method over the estimated useful lives of the various classes of assets. Depreciation expense for the years ended December 31, 2014, 2013, and 2012 was $40,041, $39,439, and $37,364, respectively. Depreciation is generally recorded over the following useful lives:
Buildings and improvements		20-40 years
Machinery and equipment		7-15 years
Furniture and fixtures		5-10 years
Computer hardware and software		3-10 years
The cost of properties retired or otherwise disposed of, together with the accumulated depreciation provided thereon, is eliminated from the accounts. The net gain or loss is recognized as a component of operating income.
Leased equipment under capital leases are amortized using the straight-line method over the term of the lease or the estimated useful life of the equipment depending on the terms of the lease contract.
Routine maintenance, repairs, and replacements are charged to operations. Expenditures that materially increase values, change capacities, or extend useful lives are capitalized.
Goodwill and intangible assets:
In the case of goodwill and intangible assets, if product demand or market conditions reduce management’s expectation of future cash flows from these assets, a write-down of the carrying value or acceleration of the amortization period may be required. Intangible assets were originally valued at fair value at the date of acquisition.
Goodwill. The Company performs its goodwill impairment testing at the reporting unit level. The Company’s four reporting units, which are one level below its operating segments, where appropriate, are as follows: 1) the Titanium reporting unit; 2) the Fabrication reporting unit; 3) the Medical Device Fabrication reporting unit; and 4) the Energy Fabrication reporting unit. As of December 31, 2014 and 2013, the Energy Fabrication reporting unit had no goodwill.
The carrying value of goodwill at the Company’s four reporting units as of the Company’s October 1, 2014 annual impairment test was as follows:
	Goodwill
Titanium reporting unit	$	24,016
Fabrication reporting unit	76,645
Medical Device Fabrication reporting unit	44,789
Energy Fabrication reporting unit	—
Total Goodwill	$	145,450
Goodwill is tested annually during the fourth quarter and is assessed between annual tests if an event occurs or circumstances change that would indicate the carrying value of a reporting unit may exceed its fair value. These events and circumstances may include, but are not limited to: significant adverse changes in the business climate or legal factors; an adverse action or assessment by a regulator; unanticipated competition; a material negative change in relationships with significant customers; strategic decisions made in response to economic or competitive conditions; loss of key personnel; or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed.
The fair value of the Company’s four reporting units is calculated by averaging the fair values determined using an income approach (i.e., a discounted cash flow model) and a market approach. A discounted cash flow model is based on historical and projected financial information and provides a fair value estimate based upon each reporting unit’s long-term operating and cash flow performance. This approach also considers the impact of cyclical downturns that occur in the titanium and aerospace industries. The market valuation approach applies market multiples, such as EBITDA and revenue multiples, developed from a set of peer group companies to each reporting unit to determine its fair value. The Company considered the use of a cost approach but determined such an approach was not appropriate.
Utilizing a discounted cash flow model, the Company estimates its cash flow projections using business and economic data available at the time the projection is calculated. A significant number of assumptions and estimates are involved in the application of the discounted cash flow model to forecast operating cash flows, including overall business conditions, sales volumes and prices, costs of production, and working capital changes. The Company considers historical experience and available information at the time the reporting units’ fair values are estimated. Discount rates were developed using a Weighted-Average Cost of Capital (“WACC”) methodology. The WACC represents the blended average required rate of return for equity and debt capital based on observed market return data and reporting unit specific risk factors.
The discount rates used in the Company’s October 1, 2014 annual impairment test were as follows:
Titanium reporting unit	11	%
Fabrication reporting unit	11.5	%
Medical Device Fabrication reporting unit	12	%
The Company performed a two-step impairment test for all reporting units with a goodwill balance as of the testing date. Step one of the goodwill impairment test indicated that the fair value of the Titanium and Fabrication reporting units each exceeded their respective carrying values by a significant margin, while the Medical Device Fabrication reporting unit’s fair value exceeded its carrying value by approximately 14% as of the testing date. As all reporting units' fair values exceeded their book values, step two was not required.
Excluding the Energy Fabrication reporting unit, whose goodwill was fully impaired in 2009, and the $13,959 impairment at the Medical Device Fabrication reporting unit in 2013, there have been no other impairments to date at the Company’s reporting units. Uncertainties or other factors that could result in a potential impairment in future periods may include any cancellation of or material modification to one of the major aerospace programs the Company currently supplies, including the Joint Strike Fighter program, the Boeing 787 program, or the Airbus family of aircraft, including the A350 XWB, A320neo, or A380 programs. In addition, the Company’s ability to maintain profitability of these programs may also impact the results of a future impairment test. Furthermore, additional pricing pressures and regulatory requirements or other impacts from the Patient Protection and Affordable Care Act could result in an additional goodwill impairment at the Medical Device Fabrication reporting unit.
The carrying amount of goodwill attributable to each segment at December 31, 2012, 2013, and 2014 was as follows:
		Titanium Segment			Engineered Products and Services Segment			Total
31-Dec-12		$	9,662		$	120,590		$	130,252
Additions		—			2,185			2,185
Impairments		—			(13,959		)	(13,959		)

Balance at December 31, 2014		$	23,873		$	121,645		$	145,518
At both December 31, 2014 and 2013, the EP&S Segment had accumulated goodwill impairment losses of $22,858, while the Titanium Segment has no accumulated impairment losses, other than those relating to discontinued operations, not included in the table above.
Intangible assets.    Intangible assets consist primarily of customer relationships, trade names, and developed technology acquired through various business combinations. These intangible assets were valued at fair value at acquisition. In the event that long-term demand or market conditions change and the expected future cash flows associated with these assets is reduced, a write-down or acceleration of the amortization period may be required. The Company has two indefinite-lived intangible assets, the Remmele trade name and the Directed Manufacturing trade name, which it does not amortize. The Company currently intends to utilize the Remmele and Directed Manufacturing trade names indefinitely. Other intangible assets are being amortized over the following periods:
Customer relationships	7-20 years
Developed technology	7-20 years
Backlog	0.5-2 years
Amortization expense was $4,835, $4,386, $3,760, for the years ended December 31, 2014, 2013, and 2012, respectively. Estimated annual amortization expense expected in each of the next five successive years is as follows:
	Amortization
2015	$	5,089
2016	$	5,047
2017	$	5,047
2018	$	5,047
2019	$	5,047
Thereafter	$	24,640
The acquisition of RTI Directed Manufacturing in January 2014 was incorporated into the EP&S Segment. The acquisition of RTI Advanced Powder Materials in June 2014 was incorporated into the Titanium Segment. The carrying amounts of intangible assets attributable to each segment at December 31, 2014, 2013, and 2012, as well as a summary of intangible assets, by class, at December 31, 2014 and 2013, are presented below:
		Titanium Segment			Engineered Products and Services Segment			Total

Management evaluates the recoverability of indefinite-lived intangible assets other than goodwill annually by using a discounted cash flow analysis based on historical and projected financial information, and assesses the recoverability of indefinite-lived intangible assets between annual tests if an event occurs or circumstances change that would indicate the carrying value of an indefinite-lived intangible asset may exceed its fair value. Several assumptions and estimates are involved in the application of the discounted cash flow model to forecast revenues, royalty rates, income tax rates, and discount rates. As of October 1, 2014, the Company’s only indefinite-lived intangible assets other than goodwill were the Remmele and Directed Manufacturing trade names. Two-step impairment analyses of the Remmele and Directed Manufacturing trade name intangible assets were performed. In each case, a fair value in excess of carrying value was determined in step one of the test, thus step two was not required. The fair values of the Remmele and Directed Manufacturing trade names were determined using a discounted cash flow model (Level 3) utilizing discount rates ranging from 12.5%-13.0%.
Other long-lived assets:
The Company evaluates the potential impairment of other long-lived assets including property, plant, and equipment and amortizable intangible assets when events or circumstances indicate that a change in value may have occurred. If the carrying value of the asset groupings exceeds the sum of the undiscounted expected future cash flows, the carrying value of the asset is written down to fair value. No such impairments were recorded during 2014.
Other non-current assets:
The Company had other non-current assets of $15,317 and $23,247 at December 31, 2014 and 2013, respectively. Other non-current assets are comprised mainly of deferred financing costs and deferred engineering costs, and are not expected to be realized within twelve months of the balance sheet date. The decrease in other non-current assets in 2014 is primarily attributable to the change in funded status of the Company's pension plans and the amortization of deferred financing fees of $1,890.
Environmental:
The Company expenses environmental costs related to potential liabilities arising in the course of business and the remediation of those liabilities. The Company determines its liability for remediation on a site-by-site basis and records a liability when it is probable and can be reasonably estimated. The estimated liability of the Company is not discounted or reduced for possible recoveries from insurance carriers.
Treasury stock:
The Company accounts for treasury stock under the cost method and includes such shares as a reduction of total shareholders’ equity.
Revenue Recognition:
Product and service revenues are recognized when persuasive evidence of an arrangement exists, product delivery has occurred or services have been rendered, pricing is fixed or determinable, and collection is reasonably assured. Service revenues are recognized as services are rendered.
Revenues under long-term construction-type contracts are recorded on a percentage-of-completion method measured on the cost-to-cost basis and the units-of-delivery basis. Prior to 2014, revenues and costs under contracts measured on the cost-to-cost method were recorded using the zero profit method under the Financial Accounting Standards Board's (the "FASB") Accounting Standards Codification ("ASC") 605-35 until the period when the Company believed it was able to estimate the total contract revenues and costs, at which point the cumulative contract gross profit earned to date was recorded. This generally occurred commensurate with the primary product under the contract being delivered. During 2014, the Company implemented a rigorous process for estimating total contract costs and revenues for all outstanding and future projects accounted for under ASC 605-35. As a result, for the majority of the Company’s contracts accounted for under ASC 605-35, the Company now recognizes costs, revenues, and related gross profit as it completes work on these projects, rather than using the zero profit method. For certain of its contracts, the full scope of work may be ill-defined at the time progress towards completion begins. For these contracts, the Company utilizes the zero profit method until such time as the full scope of the contract is defined and estimates of total costs and revenues can be determined.
Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident. No such losses have been recorded at December 31, 2014, 2013, or 2012.
Revenues from contracts with multiple element arrangements are recognized as each element is earned based on the relative fair value of each element provided the delivered elements have value to customers on a standalone basis. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price for the product or service when it is sold separately.
Value added taxes collected on sales are excluded from revenue and recorded as a liability on the Consolidated Balance Sheet until remitted to the taxing authority.
Shipping and handling fees and costs:
All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as revenue. Costs incurred by the Company for shipping and handling, including transportation costs paid to third-party shippers, are reported as a component of cost of sales. Shipping and handling expenses were immaterial for the years ended December 31, 2014, 2013, and 2012, respectively.
Research and development:
Research and development costs are expensed as incurred. These costs totaled $4,613, $3,931, and $4,164, for the years ended December 31, 2014, 2013, and 2012, respectively, and typically include employment costs, material costs, contractor fees, and other administrative costs.
Pensions:
The Company provides defined benefit pension plans for certain of its salaried and represented workforce. Benefits for its salaried participants are generally based on participants’ years of service and compensation. Benefits for represented pension participants are generally determined based on an amount for years of service. Other employees participate in 401(k) plans whereby the Company may provide a match of employee contributions. A portion of the employees in the Titanium Segment are covered by defined benefit plans in which benefits are based on years of service and annual compensation. Contributions to the defined benefit plans, as determined by an independent actuary in accordance with applicable regulations, provide not only for benefits attributed to date, but also for those expected to be earned in the future. The Company’s policy is to fund pension costs at amounts equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended, for U.S. plans plus additional amounts as may be approved from time to time.
The Company accounts for its defined benefit pension plans in accordance with the FASB’s authoritative guidance, which requires amounts recognized in the financial statements to be determined on an actuarial basis, rather than as contributions are made to the plans, and requires recognition of the funded status of the Company’s plans in its Consolidated Balance Sheet. In addition, it also requires actuarial gains and losses, prior service costs and credits, and transition obligations that have not yet been recognized to be recorded as a component of accumulated other comprehensive loss.
Other post-retirement benefits:
The Company provides health care benefits and life insurance coverage for certain of its employees and their dependents. Under the Company’s current plans, certain of the Company’s employees will become eligible for those benefits if they reach retirement age while working with the Company. In general, employees of the Titanium Segment are covered by post-retirement health care and life insurance benefits.
The Company also sponsors another post-retirement plan covering certain employees. This plan provides health care benefits for eligible employees. These benefits are accounted for on an actuarial basis, rather than as benefits are paid. The Company does not pre-fund post-retirement benefit costs, but rather pays claims as billed.
Income taxes:
Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities multiplied by the enacted tax rates which will be in effect when these differences are expected to reverse. In addition, deferred tax assets may arise from net operating losses (“NOLs”) and tax credits which may be carried back to obtain refunds or carried forward to offset future cash tax liabilities.
On a quarterly basis, the Company evaluates the available evidence supporting the realization of deferred tax assets and makes adjustments for a valuation allowance, as necessary.
Tax benefits related to uncertain tax provisions taken or expected to be taken on a tax return are recorded when such benefits meet a more-likely-than-not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that either the appropriate taxing authority has completed their examination even though the statute of limitations remains open, or the statute of limitation has expired. Interest and penalties related to uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized.
Foreign currencies:
For the Company’s foreign subsidiaries in the United Kingdom and France, whose functional currency is the U.S. dollar, monetary assets and liabilities are remeasured at current rates, non-monetary assets and liabilities are remeasured at historical rates, and revenues and expenses are translated at average rates on a monthly basis throughout the year. Resulting differences from the remeasurement process are recognized in income and reported as other income (expense).
The functional currency of the Company’s Canadian subsidiary is the Canadian dollar. Assets and liabilities are translated at period-end exchange rates. Income statement accounts are translated at the average rates of exchange prevailing during the year. Translation adjustments are reported as a component of accumulated other comprehensive loss in shareholders’ equity and are included in comprehensive income (loss).
Transactions and balances denominated in currencies other than the functional currency of the transacting entity are remeasured at current rates when the transaction occurs and at each balance sheet date. Transaction gains and losses are included in net income for the period.
Accumulated other comprehensive loss:
The components of accumulated other comprehensive loss, net of tax, on the Company’s Consolidated Balance sheet at December 31, 2014 and 2013 were as follows:
		Foreign Currency Translation			Actuarial Losses on Benefit Plans			Investment Activity			Total
Accumulated other comprehensive loss at December 31, 2011		$	10,793		$	(49,635	)	$	(8	)	$	(38,850	)
Other comprehensive loss before reclassifications, net of tax		1,915			(13,102		)	-			(11,187		)
Amounts reclassified from other comprehensive loss, net of tax		—			5,025			8			5,033

Stock-based compensation:
The Company utilizes a “graded vesting” approach to recognize compensation expense over the vesting period of stock awards. For employees who have reached retirement age, the Company recognizes compensation expense at the date of grant. For employees approaching retirement eligibility, the Company amortizes compensation expense over the period from the grant date through the retirement eligibility date.
Cash flows resulting from the windfall tax benefits from tax deductions in excess of the compensation cost recognized (“excess tax benefits”) are classified as financing cash inflows. For the years ended December 31, 2014, 2013, and 2012, operating cash flows were decreased and financing cash flows were increased by $199, $552, and $196, respectively.
Total compensation expense recognized in the Consolidated Statements of Operations for stock-based compensation arrangements was $5,670, $6,026, and $4,797 for the years ended December 31, 2014, 2013, and 2012, respectively. The total income tax benefit recognized in the Consolidated Statements of Operations for stock-based compensation arrangements was $1,361, $1,886, and $1,727 for the years ended December 31, 2014, 2013, and 2012, respectively. There was no stock-based compensation cost capitalized for the years ended December 31, 2014, 2013, and 2012.
New Accounting Standards:
In January 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2015-01, "Income Statement - Extraordinary and Unusual Items." This ASU eliminates from U.S. GAAP the concept of extraordinary items. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
In November 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2014-17, "Pushdown Accounting." This ASU provides an acquired entity with the option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. This ASU is effective as of November 18, 2014. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements.
In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements—Going Concern—Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern." The amendment requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. The guidance is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
In June 2014, the FASB issued ASU 2014-12, "Compensation—Stock Compensation—Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early application is permitted. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This ASU prescribes that an entity should recognize revenue to depict the transfer of promised 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 amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and can be adopted by the Company using either a full retrospective or modified retrospective approach. Early application is not permitted. The Company is currently evaluating the impact of the adoption of this ASU on the Company's Consolidated Financial Statements.
In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements and Property, Plant, and Equipment—Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." This ASU amends the requirements for reporting discontinued operations to include only disposals of a component or groups of components of an entity if the disposal represents a strategic shift that has or will have a major effect on the entity’s operations and financial results. The amendment requires additional disclosure regarding disposals that meet the criteria for discontinued operations in the ASU, and is effective for all disposals within annual and interim periods beginning on or after December 15, 2014. Early adoption is permitted for disposals that have not been reported in financial statements previously issued. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
In July 2013, the FASB issued ASU 2013-11, "Income Taxes—Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." This ASU prescribes the Balance Sheet presentation for unrecognized tax benefits in the presence of a net operating loss carryforward, tax loss or tax credit carryforward. The amendments in the ASU do not require any new recurring disclosures, and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.
In March 2013, the FASB issued ASU 2013-05, "Foreign Currency Matters—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU clarifies the applicable guidance for the release of the cumulative translation adjustment under current U.S. GAAP. The amendments in this ASU are effective prospectively for annual and interim reporting periods beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.
In February 2013, the FASB issued ASU 2013-04, "Liabilities—Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date." This ASU provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the ASU is fixed at the reporting date. The amendments in this ASU are effective prospectively for annual and interim reporting periods beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE:
	Earnings per share (“EPS”) amounts for each period are presented in accordance with the FASB’s authoritative guidance which requires the presentation of basic and diluted EPS. Basic EPS was computed by dividing net income attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding for each respective period. Diluted EPS was calculated by dividing net income attributable to common shareholders by the weighted-average of all potentially dilutive shares of Common Stock that were outstanding during the periods presented.
	At December 31, 2014, the Company had $114,381 aggregate principal amount of the 2015 Notes and $402,500 aggregate principal amount the 2019 Notes outstanding. Shares underlying the 2019 Notes and the 2015 Notes and certain stock options were excluded from the calculation of EPS as their effects were antidilutive.

	Effective tax rate	24		%	31.3		%	53.8		%
	The effective tax rates in each year vary from the U.S. federal statutory rate of 35% principally due to the effects of foreign operations, changes in the valuation allowance on the Company’s Canadian net deferred tax asset, the benefit of the I.R.C. §199 domestic production activities deduction, adjustments to unrecognized tax benefits, and state taxes. The effects of foreign operations include the impact of lower foreign statutory tax rates, certain statutory allowances, foreign exchange rate movements, and modest amounts of US foreign tax credits. These factors and the mix and relative levels of domestic and foreign income or loss significantly influence each year’s overall effective tax rate. In 2014, the Company’s Canadian subsidiary was profitable, resulting in a reversal of a portion of the valuation allowance on the Canadian net deferred tax asset, while losses in 2013 and 2012 increased the valuation allowance. In 2013, the state income tax benefit related to a change in Pennsylvania state tax law to market based sourcing of revenue and the increase to the effective tax rate for goodwill impairment related to the impairment of goodwill at the Company’s Medical Device Fabrication reporting unit for which there was no corresponding tax basis.
	Deferred tax assets and liabilities resulted from the following:
		December 31,
		2014			2013
	Deferred tax assets:
	Canadian tax loss carryforwards (expiring 2026 through 2033)	$	34,346		$	39,989

	Convertible debt	(27,325		)	(33,511		)
	Intangible assets	(14,899		)	(15,063		)
	Other	(1,091		)	(973		)
	Total deferred tax liabilities	(100,501		)	(108,403		)
	Net deferred tax liabilities	$	(29,117	)	$	(42,048	)
	A significant portion of the valuation allowance at December 31, 2014 and 2013 is attributable to the Company’s Canadian net deferred tax asset against which, due to the Company’s Canadian subsidiary’s cumulative losses over a number of years, the Company has recorded a full valuation allowance, net of its Canadian deferred tax liabilities. The Company has also recorded valuation allowances against certain state deferred tax assets pertaining to the related state tax loss carry-forwards that are not anticipated to generate a tax benefit.
	The Company's Canadian subsidiary generated net taxable losses totaling $134.4 million from 2005 through 2014, resulting in a Canadian net deferred tax asset of $27.6 million as of December 31, 2014. The Company has recorded a full valuation allowance against its Canadian net deferred tax asset as of December 31, 2010, and for each subsequent period thereafter. The realization of the Canadian deferred tax assets is dependent upon the ability to generate future taxable income at the Company's Canadian subsidiary. Despite the utilization of some the Canadian subsidiary’s net operating loss carryforwards in 2014, there has not been an established pattern of net income earned in recent years. In addition, the lack of certainty of future earnings sufficient to utilize the remaining loss carryforwards causes the negative evidence of prior year losses to outweigh the potential for future earnings, resulting in a need to maintain the current valuation allowance against the net operating loss carryforwards. The Company will continue to review whether a valuation allowance against the Canadian net deferred tax asset is required. If it is determined that the realization of some or all of the Canadian net deferred tax assets is more likely than not, some or all of the valuation allowance will be reversed.
	A reconciliation of the total amounts of unrecognized tax benefits for the years ended December 31, 2014, 2013, and 2012 is as follows:
		Unrecognized Tax Benefits
		2014			2013			2012
	Gross balance at January 1	$	8,427		$	9,161		$	6,157
	Prior period tax positions:
	Increases	1,425			861			1,556
	Decreases	(358		)	(2,109		)	(30		)
	Current period tax positions	2,825			1,608			1,478
	Lapse of Statute	(1,789		)	—			—
Settlements with tax authorities	—			(1,094		)	—
Gross balance at December 31	$	10,530		$	8,427		$	9,161
Amount that would affect the effective tax rate if recognized	$	7,489		$	6,168		$	5,946
The Company’s unrecognized tax benefits principally relate to the sale of products and provision of services by the Company’s U.S. subsidiaries to its foreign subsidiaries. The decrease in prior period tax positions in 2013 resulted from an audit settlement. The settlements with tax authorities in 2013 represents tax payments to tax authorities as a result of an audit settlement. It is reasonably possible that the total amount of unrecognized tax benefits could be decreased within the next twelve months by approximately $3.4 million.
The Company classifies interest and penalties as an element of tax expense. The amount of tax-related interest and penalties recognized in the Consolidated Statement of Operations for fiscal years 2014, 2013, and 2012, and the total of such amounts accrued in the Consolidated Balance Sheets at December 31, 2014 and 2013 were not material.
The Company’s U.S. Federal income tax returns for tax years 2011, 2012 and 2013 remain open to examination. The Company’s U.S. federal income tax return for 2012 is currently under examination. The field examination of the Company’s Canadian tax returns for tax years 2006 and 2007 by the Canadian Revenue Authority (“CRA”) was completed in 2013. The Company filed an administrative appeal of the agent’s proposed adjustments which was recently decided favorably by CRA resulting in an acceptance of the returns as filed. The examination of the tax year 2008 by CRA is continuing. Tax years after 2008 are open to examination by CRA.
Undistributed earnings of certain foreign subsidiaries considered to be indefinitely reinvested or which may be remitted tax free in certain situations, amounted to $4.1 million at December 31, 2014. The Company has determined that the deferred tax liability associated with these undistributed earnings, net of embedded foreign tax credits, is not material.

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS:
	The Company provides defined benefit pension plans for certain of its salaried and represented workforce. Benefits for its salaried participants are generally based on participants’ years of service and compensation. Benefits for represented pension participants are generally determined based on an amount for years of service. Other employees participate in 401(k) plans whereby the Company may provide a match of employee contributions. The policy of the Company with respect to its defined benefit plans is to contribute at least the minimum amounts required by applicable laws and regulations. For the years ended December 31, 2014, 2013, and 2012, expenses related to 401(k) plans were approximately $4,960, $4,199, and $3,390, respectively.
	As of the signing of the Labor Agreement with USW at the Niles, Ohio plant on December 1, 2004, all new hourly, clerical and technical employees covered by the Labor Agreement are covered by a defined contribution pension plan rather than a defined benefit plan. Effective January 1, 2006, all new salaried non-represented employees in the Titanium Segment are covered by a defined contribution pension plan rather than a defined benefit plan. As a result of these changes, no future hires will be covered by defined benefit pension plans. During 2013, the Company offered a voluntary early retirement program to certain qualifying employees. As a result, the Company recorded expense of $3,196 in net periodic benefit cost during 2013.
	The Company uses a December 31 measurement date for all benefit plans. The following table provides reconciliations of the changes in the Company’s pension and other post-employment benefit plan obligations, the values of plan assets, amounts recognized in Company’s financial statements, and principal weighted-average assumptions used:

Rate of increase to compensation levels — non-qualified plans		2.9	%		2.9	%		N/A			N/A
The Company’s expected long-term return on plan assets assumption is based on a periodic review and modeling of each plan’s asset allocation and liability structure over a long-term horizon. Expectations of returns for each asset class are the most important of the assumptions used in the review and modeling and are based on comprehensive reviews of historical data and economic/financial market theory. The expected long-term rate of return on assets was selected from within the reasonable range of rates determined by (a) historical real returns, net of inflation, for the asset classes covered by the investment policy and (b) projections of inflation over the long-term period during which benefits are payable to plan participants.
A change of one quarter of a percentage point in the expected rate of return on plan assets would have the following effect on the defined benefit plan:
		-0.25%				0.25%
Effect on subsequent years periodic pension expense (in millions)		$	0.4			$	(0.4	)
The discount rate is used to determine the present value of future payments. In general, the Company’s liability increases as the discount rate decreases and decreases as the discount rate increases. The discount rate was determined by taking into consideration an above-mean yield curve model in order to select a discount rate that best matches the expected payment streams of the future payments. The model is developed using bonds with a Moody’s or Standard & Poor’s rating of “Aa” or better based on those bonds available as of the measurement date. The appropriate discount rate is then selected based on the resulting yield from this portfolio.
A change of one-quarter of a percentage point in the discount rates used at December 31, 2014 would have the following effect on the defined benefit plans:
		-0.25%				0.25%
Effect on total projected benefit obligation ("PBO") (in millions)		$	5.6			$	(5.3	)
Effect on subsequent years periodic pension expense (in millions)		$	0.3			$	(0.3	)
A change of one-quarter of a percentage point in the discount rate used at December 31, 2014 would have the following effect on the postretirement medical plan:
		-0.25%				0.25%
Effect on accumulated postretirement benefit obligation (in millions)		$	1.6			$	(1.5	)
Effect on total net periodic benefit cost (in millions)		$	0.1			$	(0.1	)
A change of one percentage point in the health cost trend rate of 6.68% used at December 31, 2014 would have the following effect on the postretirement medical plan:
		-1.00%				1.00%
Effect on total service cost and interest cost components (in millions)		$	(0.2	)		$	0.2
Effect on accumulated postretirement benefit obligation (in millions)		$	(2.2	)		$	2.5

The Company’s investment policy for the defined benefit pension plans includes various guidelines and procedures designed to ensure assets are invested in a manner necessary to meet expected future benefits earned by participants. The investment guidelines consider a broad range of economic conditions. Central to the policy are target allocation ranges, shown above, by major asset categories. The objectives of the target allocations are to maintain investment portfolios that diversify risk through prudent asset allocation parameters, achieve asset returns that meet or exceed the plans’ actuarial assumptions, and achieve asset returns that are competitive with like institutions employing similar investment strategies. Within these broad investment categories, the Company’s investment policy places certain restrictions on the types and amounts of plan investments. For example, no individual stock may account for more than 5% of total equities, no single corporate bond issuer rated below AA may equal more than 10% of the total bond portfolio, non-investment grade bonds may not exceed 10% of the total bond portfolio, and private equity and real estate investments may not exceed 8% of total plan assets.
The Company and a designated third-party fiduciary periodically review the investment policy. The policy is established and administered in a manner so as to comply at all times with applicable government regulations.
The Company uses appropriate valuation techniques based on the available inputs to measure the fair value of plan investments. When available, the Company measures the fair value using Level 1 inputs as they generally provide the most reliable evidence of fair value. When Level 1 and Level 2 inputs are not available, the Company uses Level 3 inputs to fair value its plan assets. A summary of the plan investments, their fair value and their level within the fair value hierarchy is presented below.

Level 1 Fair Value Measurements:
Short-term Investment Funds — Short-term Investment Funds are carried at the reported net asset values.
Equities — The fair values of equities are based upon quoted market prices.
Level 2 Fair Value Measurements:
Corporate Bonds and U.S. Government Securities — The plans hold certain U.S. government securities and corporate bonds in a limited partnership with the assets of other plan sponsors. The fair values of these securities held in the partnership are based upon quoted market prices.
Equities — The plans hold common stock in a limited partnership with the assets of other plan sponsors.
The fair values of these securities held in the partnerships are based upon quoted market prices.
Level 3 Fair Value Measurements:
Equities (Private Equity Funds) and Real Estate Funds — The fair value of private equity funds and real estate funds are determined by the fair value of the underlying investments in the funds plus working capital adjusted for liabilities, currency translation and estimated performance incentives. Various methods of determining the fair value of the underlying assets in each fund are used which may include, but are not limited to, expected cash flows, multiples of earnings, discounted cash flow models, direct capitalization analyses, third-party appraisals and other market-based information. Valuations are reviewed utilizing available market data to determine whether or not any fair value adjustments are necessary.
Timberlands — The value of the Timberlands investment is based upon the appraised value of the Timberlands plus net working capital. It is based upon inventory obtained pursuant to a review of this inventory at the time of acquisition, updated periodically based upon a cash projection model for a 50-year period using real prices and a real discount rate based upon current market activity. Valuations are reviewed utilizing industry information to determine whether or not any fair value adjustments are necessary.

Other post-retirement benefit plans.    The ultimate costs of certain of the Company’s retiree health care plans are capped at predetermined out-of-pocket spending limits. The annual rate of increase in the per capita costs for these plans is limited to the predetermined spending cap.
All of the benefit payments are expected to be paid from Company assets. These estimates are based on current benefit plan coverages and, in accordance with the Company’s rights under the plan, these coverages may be modified, reduced, or terminated in the future.
The following pension and post-retirement benefit payments, which reflect expected future service, as appropriate, are expected to be paid:
		Pension Benefit Plans				Post-Retirement Benefit Plan (including Plan D subsidy)				Post-Retirement Benefit Plan (not including Plan D subsidy)

The Company contributed $1,100 and $4,320 to its qualified defined benefit pension plans in 2014 and 2013, respectively. No additional contributions are expected to be required for the Company to maintain its desired funding status in 2015.
Supplemental pension plan.    Company officers who participate in the incentive compensation plan are eligible for the Company’s supplemental pension plan which entitles participants to receive additional pension benefits based upon their annual bonuses paid under the incentive compensation plan. Participation in this plan is subject to approval by the Company’s Board of Directors.
Excess pension plan.    The Company sponsors an excess pension plan for designated individuals whose salary amounts exceed IRS limits allowed in the Company’s qualified pension plans. Participation in this plan is subject to approval by the Company’s Board of Directors.
The supplemental and excess pension plans are included and disclosed within the pension benefit plan information within this Note.
Employee Stock Purchase Plan.    At the Company’s 2009 Annual Meeting of Shareholders, its shareholders approved the Employee Stock Purchase Plan (the “ESPP”), which authorized the issuance of 2.0 million shares of the Company’s Common Stock for purchase by eligible employee participants through payroll deductions. Employees purchase shares in each quarterly purchase period at a 5% discount to the fair market value of the Company’s Common Stock on the valuation date. Under current accounting guidance, the ESPP qualifies as a non-compensatory plan.
Approximately 49,000 shares have been purchased under the ESPP since its inception. As of December 31, 2014, more than 1.9 million shares of the Company’s Common Stock remained available for future purchase under the ESPP.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING:
	The Company’s chief operating decision maker is the Vice Chair, President, and Chief Executive Officer. The Company conducts its operations in two reportable segments: the Titanium Segment and the EP&S Segment. Refer to Note 1 of these Consolidated Financial Statements for a description of each reportable segment.
	The EP&S Segment utilizes the Titanium Segment as its primary source of titanium mill products. Intersegment sales are accounted for at prices that are generally established by reference to similar transactions with unaffiliated customers. Reportable segments are measured based on segment operating income after an allocation of certain corporate items such as general corporate overhead and expenses. Assets of general corporate activities include unallocated cash and deferred taxes. A summary of financial information by reportable segment is as follows:

In the years ended December 31, 2014, 2013, and 2012, export sales were $229,642, $234,664, and $249,472, respectively, principally to customers in Western Europe. Geographic location of trade sales are determined based on the location of customers.
Substantially all of the Company’s sales and operating revenues are generated from its North American and European operations. A significant portion of the Company’s sales are made to customers in the aerospace industry. For the years ended December 31, 2014, 2013, and 2012, Boeing, through multiple contracts with various Company subsidiaries covering varying periods, accounted for approximately 25.2%, 21.2%, and 12.0%, respectively, of the Company’s consolidated net sales. Additionally, for each year presented, Airbus and its subcontractors together aggregate to amounts in excess of 10% of the Company’s consolidated net sales and are the ultimate consumers of a significant portion of the Company’s commercial aerospace products.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES:
	From time to time, the Company is involved in litigation relating to claims arising out of its operations in the normal course of business. In the Company’s opinion, the ultimate liability, if any, resulting from these matters will have no significant effect on its Consolidated Financial Statements. Given the critical nature of many of the aerospace end uses for the Company’s products, including specifically their use in critical rotating parts of gas turbine engines, the Company maintains aircraft products liability insurance of $500 million, which includes grounding liability.
	Environmental Matters
	The Company is subject to environmental laws and regulations as well as various health and safety laws and regulations that are subject to frequent modifications and revisions. During the years ended 2014, 2013, and 2012 the Company paid approximately $47, $14, and $72, respectively, for environmental remediation, compliance, and related services. While the costs of compliance for these matters have not had a material adverse impact on the Company in the past, it is impossible to accurately predict the ultimate effect these changing laws and regulations may have on the Company in the future. The Company continues to evaluate its obligation for environmental-related costs on a quarterly basis and make adjustments as necessary.
	Given the status of the proceedings at certain of the Company’s sites and the evolving nature of environmental laws, regulations, and remediation techniques, the Company’s ultimate obligation for investigative and remediation costs cannot be predicted. It is the Company’s policy to recognize environmental costs in the financial statements when an obligation becomes probable and a reasonable estimate of exposure can be determined. When a single estimate cannot be reasonably made, but a range can be reasonably estimated, the Company accrues the amount it determines to be the most likely amount within that range.
	Based on available information, the Company believes that its share of possible environmental-related costs is in a range from $536 to $2,056 in the aggregate. At December 31, 2014 and 2013, the amounts accrued for future environmental-related costs were $1,216 and $1,263, respectively. Of the total amount accrued at December 31, 2014, $85 is expected to be paid out within one year and is included as a component of other accrued liabilities on the Company’s Consolidated Balance Sheet. The remaining $1,131 is recorded as a component of other noncurrent liabilities in the Company’s Consolidated Balance Sheet.
	The following table summarizes the changes in the Company’s environmental liabilities for the year ended December 31, 2014:
		Environmental
		Liabilities
	Balance at December 31, 2013	$	1,263
	Environmental-related expense	—
	Cash paid	(47		)
	Balance at December 31, 2014	$	1,216
	As these proceedings continue toward final resolution, amounts in excess of those already provided may be necessary to discharge the Company from its obligations for these sites.
	Other Matters
	The Company is also the subject of, or a party to, a number of other pending or threatened legal actions involving a variety of matters incidental to its business. The Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on the results of the operations, cash flows or the financial position of the Company.

	Interest on the 2019 Notes is payable in arrears on April 15 and October 15 of each year, at a rate of 1.625% per annum. The 2019 Notes are the Company’s senior unsecured obligations. The 2019 Notes are jointly and severally, fully and unconditionally (subject to the customary exceptions discussed below) guaranteed by several 100% owned subsidiaries (the “Guarantor Subsidiaries”) of RTI International Metals, Inc. (the “Parent”). Each Guarantor Subsidiary would be automatically released from its guarantee of the 2019 Notes if either (i) it ceased to be a guarantor under the Parent’s $150 million revolving credit facility under its Second Amended and Restated Credit Agreement (the “Credit Agreement”), which expires on May 23, 2017 or (ii) it ceased to be a direct or indirect subsidiary of the Parent. Refer to Note 16 of these Consolidated Financial Statements for additional information about the Guarantor Subsidiaries.
	The 2019 Notes are convertible at the option of the holder prior to the close of business on the business day immediately preceding April 15, 2019 only under the following circumstances: (1) during any calendar quarter commencing after June 30, 2013 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable conversion price of $40.72 per share on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which, for each trading day of such measurement period, the trading price per $1,000 principal amount of notes on such trading day was less than 98% of the product of the last reported sale price of the Company's common stock on such trading day and the applicable conversion rate on such trading day; or (3) upon the occurrence of specified corporate transactions.
	Irrespective of the conditions above, the 2019 Notes will be convertible at the applicable conversion rate at any time on or after April 15, 2019, until the close of business on the second scheduled trading day immediately preceding the maturity date. The current conversion rate for the 2019 Notes equals 24.5604 shares of common stock per $1,000 principal amount of 2019 Notes (equivalent to a conversion price of approximately $40.72 per share of Common Stock). Upon conversion, holders of the 2019 Notes will receive, at the Company’s election, cash, shares of the Company’s Common Stock, or a combination of both.
	The FASB's authoritative guidance requires convertible notes that may be settled in cash to be bifurcated into a liability component and an equity component. The fair value of the liability component is determined by calculating the present value of the cash flows of the convertible note using the interest rate of a bond of similar size and rating without a conversion feature (i.e., straight-debt). The fair value of the equity component is the difference between the proceeds from the issuance and the fair value of the liability.
	The Company determined similar straight-debt had an interest rate of 5.875% at the time the 2019 Notes were issued. As a result, the fair value of the liability component of the 2019 Notes was calculated to be $311.2 million and was recorded as long-term debt. The conversion component of the 2019 Notes has a fair value of $91.3 million and was recorded, net of deferred taxes, as additional paid-in capital. The debt component of the 2019 Notes will accrete to the 2019 Notes’ par value of $402.5 million over the 2019 Notes’ 6.5 year term. Debt accretion is recorded in the Company’s Consolidated Statement of Operations as a component of interest expense. The Company is accreting the long-term debt balance to par value using the interest method.
	In conjunction with the issuance of the 2019 Notes, the Company incurred debt issuance costs totaling $12.4 million. Under the FASB’s authoritative guidance, debt issuance costs for the 2019 Notes should be allocated to the liability and equity components in proportion to their respective fair values. As such, $2.8 million of these costs were attributed to the conversion feature of the 2019 Notes and was recorded, net of deferred taxes, as additional paid-in capital. The remaining $9.6 million of debt issuance costs were attributed to the liability component of the 2019 Notes and were capitalized in the Company’s Consolidated Balance Sheet as a component of other current and noncurrent assets. The portion of the costs attributed to the debt component of the 2019 Notes is being amortized over the term of the 2019 Notes using the interest method. Amortization of these costs is included as a component of interest expense in the Company’s Consolidated Statement of Operations.
	Commensurate with the issuance of the 2019 Notes, the Company repurchased, through individually negotiated private transactions, $115.6 million aggregate principal amount of its 2015 Notes for cash consideration of $133.4 million, including $1.3 million of accrued interest on the repurchased 2015 Notes. The FASB’s authoritative guidance regarding repurchases of convertible notes requires that the consideration paid be separated into a component to repurchase the debt instrument and a component to derecognize the equity component. The fair value of the liability component at repurchase is determined by calculating the present value of the cash flows of the note at a similar size and rating without a conversion feature as of the repurchase date. The fair value of the equity component is the difference between the consideration paid and the fair value of the liability component.
	The Company determined similar straight-debt had an interest rate of 3.535% at the time the 2015 Notes were repurchased. Using this rate, the fair value of the liability component of the repurchased 2015 Notes was calculated to be $112.6 million while the equity component of the repurchased 2015 Notes was calculated to be $19.5 million. The book value of the liability component of the repurchased 2015 Notes was $100.4 million as of the repurchase date. The $12.2 million excess of consideration paid for the liability component of the repurchased 2015 Notes over their book value represents a debt extinguishment charge and was recorded as a component of interest expense in the Consolidated Statement of Operations. Unamortized debt issuance costs totaling $1.5 million related to the repurchased 2015 Notes were also expensed as a component of interest expense in conjunction with the repurchase.
	The Company determined similar straight-debt rates were 8.675% at the time the 2015 Notes were issued. As a result, at issuance, the fair value of the liability component of the 2015 Notes was calculated to be $177.7 million and was recorded as long-term debt. The conversion component of the 2015 Notes had a fair value of $52.3 million and was recorded, net of deferred taxes, as additional paid-in capital. The debt component of the 2015 Notes will accrete to the 2015 Notes’ remaining par value of $114.4 million over the 2015 Notes’ five-year term. Debt accretion is recorded in the Company’s Consolidated Statement of Operations as a component of interest expense. The Company is accreting the long-term debt balance to par value using the interest method.
	In conjunction with the issuance of the 2015 Notes, the Company incurred debt issuance costs totaling $7.2 million. Under the FASB’s authoritative guidance, debt issuance costs for the 2015 Notes should be allocated to the liability and equity pieces in proportion to the fair value. As such, $1.6 million of these costs was attributed to the conversion feature of the 2015 Notes and was recorded, net of deferred taxes, as additional paid-in capital. The remaining $5.6 million of debt issuance costs were attributed to the liability component of the 2015 Notes and were capitalized in the Company’s Consolidated Balance Sheet as a component of other noncurrent assets. The portion of the costs attributed to the debt component of the remaining $114.4 million aggregate principal 2015 Notes is being amortized over the term of the Notes using the interest method. Amortization of these costs is included as a component of interest expense in the Company’s consolidated statement of operations.
	Interest on the remaining $114.4 million aggregate principal 2015 Notes is payable semiannually in arrears on June 1 and December 1 of each year, at a rate of 3.00% per year. The Notes are senior unsecured obligations of the Company. The Notes are jointly and severally, fully and unconditionally (subject to the same customary exceptions as the 2019 Notes, discussed above) guaranteed by the Guarantor Subsidiaries, which are the same subsidiaries that guarantee the Company’s obligations under the 2019 Notes and the current credit facility.
	The 2015 Notes are convertible at the option of the holder prior to the close of business on the business day immediately preceding June 1, 2015 only under the following circumstances: (1) during any calendar quarter commencing after December 31, 2010 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable conversion price of $35.91 per share on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which, for each trading day of such measurement period, the trading price per $1,000 principal amount of notes on such trading day was less than 98% of the product of the last reported sale price of the Company's common stock on such trading day and the applicable conversion rate on such trading day; or (3) upon the occurrence of specified corporate transactions.
	Irrespective of the conditions above, the 2015 Notes will be convertible at the applicable conversion rate at any time on or after June 1, 2015, until the close of business on the second scheduled trading day immediately preceding the maturity date. The current conversion rate for the Notes equals 27.8474 shares of common stock per $1,000 principal amount of Notes (equivalent to a conversion price of $35.91 per share of Common Stock). Upon conversion, holders will receive, at the Company’s election, cash, shares of the Company’s Common Stock, or a combination of both.
	During the years ended December 31, 2014, 2013, and 2012, the Company recorded long-term debt discount amortization of $18,132, $14,956, and $9,683 as a component of interest expense. Interest expense from the amortization of debt issuance costs associated with the Notes was $1,890, $1,484, and $1,120 for the years ended December 31, 2014, 2013, and 2012, respectively.
	On May 23, 2012, the Company entered into the Credit Agreement, which provides for a revolving credit facility of $150 million and matures on May 23, 2017. Borrowings under the Credit Agreement bear interest, at the Company’s option, at a rate equal to LIBOR plus an applicable margin or the base rate plus an applicable margin. Both the applicable margin and the facility fee vary based upon the Company’s consolidated net debt to consolidated EBITDA ratio, as defined in the Credit Agreement.
	The Company’s leverage ratio (the ratio of Net Debt to Consolidated EBITDA, as defined in the Credit Agreement) was 2.25 to 1 at December 31, 2014. If this ratio were to exceed 3.50 to 1, the Company would be in default under the Credit Agreement.
	The Company’s coverage ratio (the ratio of Consolidated EBITDA to Net Interest, as defined in the Credit Agreement) was 11.66 to 1 at December 31, 2014. If this ratio were to fall below 2.0 to 1, the Company would be in default under the Credit Agreement.
	Consolidated EBITDA, as defined in the Credit Agreement, allows for adjustments related to unusual gains and losses, certain noncash items, and certain non-recurring charges. As of December 31, 2014, the Company was in compliance with all financial covenants under the Credit Agreement.
	The Company had no borrowings outstanding under the Credit Agreement at December 31, 2014 or December 31, 2013.

StockBased_Compensation

Stock-Based Compensation	12 Months Ended
	Dec. 31, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION:
	Shares awarded under stock-based compensation plans in 2014 were awarded under the 2004 Stock Plan (the “2004 Plan”) until the Annual Meeting in April 2014, when the 2014 Stock and Incentive Plan (the “2014 Plan”) was approved by the Company’s shareholders. The majority of shares awarded under stock-based compensation plans in 2014 were issued under the 2004 Plan, under which no new grants were permissible after the ten-year anniversary of the effective date of the 2004 Plan. The 2004 Plan, which was approved by a vote of the Company’s shareholders at the 2004 Annual Meeting of Shareholders, was the successor to the 1995 Stock Plan (the “1995 Plan”) and the 2002 Non-Employee Director Stock Option Plan (the “2002 Plan”).
	The 2014 Plan limits the number of shares available for issuance to 3,500,000, plus any shares covered by stock options already outstanding under the 2004 Plan that expire or are terminated without being exercised and any shares delivered in connection with the exercise of any outstanding awards under the 2004 Plan, and limits the amount of shares for issuance upon the exercise of incentive stock options to 2,000,000. While the 2014 Plan allows for the issuance of shares from treasury, the Company currently issues authorized, unissued shares for awards under the 2014 Plan. The 2014 Plan will remain effective until terminated by the Company or until all awards issued under the 2014 Plan have been exercised, vested, satisfied, forfeited or expired, as applicable. The 2014 plan requires that the exercise price of stock options, stock appreciation rights, and other similar instruments awarded be not less than the fair market value of the Company’s stock on the date of the grant award.
	Restricted stock awards under the 2014 Plan vest with graded vesting over a period of at least three years, with the exception of up to an aggregate 5% of the total shares authorized to be issued under the plan, for which the minimum vesting period shall not apply. As determined by the Compensation Committee of the Board of Directors (the "Compensation Committee"), awards under the 2004 Plan vest with graded vesting over a period of one to five years. Restricted stock awarded under the 2014 Plan and the predecessor plans entitle the holder to all the rights of Common Stock ownership except that the shares may not be sold, transferred, pledged, exchanged, or otherwise disposed of during the forfeiture period. Restricted stock units issued under the 2014 Plan do not receive dividends or voting rights. The stock option awards issued under the 2014 Plan vest with graded vesting over a period of no less than three years, while awards under the 2004 Plan vest, as determined by the Compensation Committee, with graded vesting over a period of one to three years. Certain stock option and restricted stock awards under the 2004 Plan provide for accelerated vesting if there is a change in control.
	Stock Options
	The fair value of stock options granted over the past three years was estimated at the date of grant using the Black-Scholes option-pricing model based upon the following assumptions:
		2014		2013		2012
	Risk-free interest rate	1.51	%	0.87	%	0.75	%
	Expected dividend yield	0	%	0	%	0	%
	Expected lives (in years)	5		5		5
	Expected volatility	55	%	65	%	66	%
	The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The risk-free rate for periods over the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore an expected dividend yield of zero is used. The expected life of options granted represents the period of time that options granted are expected to be outstanding. Expected volatilities are based on historical volatility of the Company’s Common Stock. Forfeiture estimates are based upon historical forfeiture rates.
	A summary of the status of the Company’s stock options as of December 31, 2014 and the activity during the year then ended is presented below:
	Stock Options	Shares		Weighted-Average Exercise Price Per Share			Weighted-Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
	Outstanding at December 31, 2013	526,736		$	34.56
	Granted	103,472		30.59

	Outstanding at December 31, 2014	528,680		$	34.45		5.69	$	414
	Exercisable at December 31, 2014	365,666		$	36.73		4.42	$	399
	The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2014, 2013, and 2012 was $14.73, $15.80, and $13.49 per share, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2014, 2013, and 2012 was $298, $1,892, and $525, respectively. As of December 31, 2014, total unrecognized compensation cost related to nonvested stock option awards granted was $742. That cost is expected to be recognized over a weighted-average period of approximately eight months.
	Cash received from stock option exercises under all share-based payment arrangements for the years ended December 31, 2014, 2013, and 2012 was $811, $2,290, and $494, respectively. Cash used to settle equity instruments granted under all share-based arrangements for the years ended December 31, 2014, 2013, and 2012 was $851, $399, and $742, respectively. The actual tax benefit realized for the tax deductions resulting from stock option exercises and vesting of restricted stock awards for share-based payment arrangements totaled $(192), $(4), and $27 for the years ended December 31, 2014, 2013, and 2012, respectively.
	Restricted Stock
	The fair value of the nonvested restricted stock awards was calculated using the market value of Common Stock on the date of issuance. The weighted-average grant-date fair value of restricted stock awards granted during the years ended December 31, 2014, 2013, and 2012 was $29.28, $29.00, and $24.63 per share, respectively.
	A summary of the status of the Company’s non-vested restricted stock as of December 31, 2014, and the activity during the year then ended, is presented below:
	Nonvested Restricted Stock Awards	Shares		Weighted-Average Grant-Date Fair Value Per Share
	Nonvested at December 31, 2013	213,475		$	26.88
	Granted	100,417		29.28
	Vested	(92,459	)	25.91
	Forfeited	(22,364	)	28.67
	Nonvested at December 31, 2014	199,069		$	28.35
	As of December 31, 2014, total unrecognized compensation cost related to nonvested restricted stock awards granted was $2,141. That cost is expected to be recognized over a weighted-average period of twelve months. The total fair value of restricted stock awards vested during the years ended December 31, 2014, 2013, and 2012 was $2,808, $2,199, and $1,507, respectively.
	Performance Share Awards
	The Company also maintains performance share awards for executive officers and certain key managers. The purpose of the performance share awards is to more closely align the compensation of the Company’s executives and key managers with the interests of the Company’s shareholders. Performance share awards issued in 2014 have both market and performance vesting conditions. The payout of fifty percent of the awards is based upon the Company’s total shareholder return compared to the total shareholder return of a relative peer group over a three-year period, while the payout of the remaining fifty percent of the awards is based upon the Company’s annual diluted earnings per share growth over a three-year period. Performance share awards issued prior to 2014 will earn shares of the Company’s Common Stock in amounts ranging from 0% to 200% of the target number of shares based upon the total shareholder return of the Company compared to the total shareholder return of a designated peer group over a pre-determined performance period.
	A summary of the Company’s performance share activity during the year ended December 31, 2014 is presented below:
	Performance Share Awards	Awards Activity		Maximum Shares Eligible to Receive
	Outstanding at December 31, 2013	154,333		308,666
	Granted	70,875		141,750
	Vested	(42,442	)	(84,884	)
	Forfeited	(25,683	)	(51,366	)
	Outstanding at December 31, 2014	157,083		314,166
	The performance share awards issued in 2014 have both market and performance vesting conditions. The fair value of the market condition was determined using a Monte Carlo model. A Monte Carlo model uses stock price volatility and other variables to estimate the probability of satisfying market conditions and the resulting fair value of the award. The four primary inputs for the Monte Carlo model are the risk-free rate, expected dividend yield, volatility of returns, and correlation of returns within the designated peer group. The risk-free rate for periods over the expected term of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore an expected dividend yield of zero is used. Expected volatility and correlation of returns are based on historical performance of the Company’s stock.
	The fair value of the performance condition was determined using the market value of the Company’s Common Stock on the date of issuance. Expense on these awards is recognized over the performance period and is determined based on the probability that the performance targets will be achieved. The weighted-average grant-date fair value of these shares awarded during the year-ended December 31, 2014 was $34.96.
	The weighted-average grant-date fair value of performance shares awarded during the years ended December 31, 2013 and 2012 was $41.02 and $35.59, respectively.

Condensed Financial Information of Parent Company Only Disclosure [Abstract]
GUARANTOR SUBSIDIARIES	GUARANTOR SUBSIDIARIES:
	Each of the 2015 Notes and 2019 Notes (collectively, the "Notes”) is jointly and severally, fully and unconditionally (subject to the customary exceptions discussed below) guaranteed by the Guarantor Subsidiaries. Each Guarantor Subsidiary would be automatically released from its guarantee of the Notes if either (i) it ceases to be a guarantor of the Parent’s Credit Agreement or (ii) it ceases to be a subsidiary of the Parent. Separate financial statements of the Parent and each of the Guarantor Subsidiaries are not presented because the guarantees are full and unconditional (subject to the aforementioned customary exceptions) and the Guarantor Subsidiaries are jointly and severally liable. The Company believes separate financial statements and other disclosures concerning the Guarantor Subsidiaries would not be material to investors in the Notes.
	There are no current restrictions on the ability of the Guarantor Subsidiaries to make payments under the guarantees referred to above, except, however, the obligations of each Guarantor Subsidiary under its guarantee will be limited to the maximum amount as will result in obligations of such Guarantor Subsidiary under its guarantee not constituting a fraudulent conveyance or fraudulent transfer for purposes of bankruptcy law, the Uniform Conveyance Act, the Uniform Fraudulent Transfer Act, or any similar Federal or state law.
	The following tables present Condensed Consolidating Financial Statements as of December 31, 2014 and 2013 and for the three years ended December 31, 2014.

-1	Intercompany investments include equity investments and intercompany loans receivable from legal entities not included within the same consolidation.
-2	The Condensed Consolidating Balance sheet has been adjusted to correct the prior presentation of intercompany debt and investment balances. Previously, certain intercompany debt and investment balances had been netted, resulting in the understatement of total assets and liabilities of both the Guarantor Subsidiaries and Non-Guarantor Subsidiaries, as well as understatement of Guarantor Subsidiaries Shareholders’ Equity. These adjustments increased (decreased) intercompany investments by $82,070, $103,917, and $(185,987); intercompany debt by $44,970, $103,917, and $(148,887); and shareholders’ equity by $37,100, $0, and $(37,100) for Guarantor Subsidiaries, Non-Guarantor Subsidiaries, and Eliminations, respectively.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation:
	The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), and include the accounts of RTI International Metals, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated
Use of estimates	Use of estimates:
	U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at year-end and the reported amounts of revenues and expenses during the year. Actual results could differ from these estimates. Significant items subject to such estimates and assumptions include the carrying values of accounts receivable, inventories, property, plant, and equipment, intangible assets, goodwill, pensions, post-retirement benefits, worker’s compensation, environmental liabilities, and income taxes.
Fair value	Fair value:
	For certain of the Company’s financial instruments and account groupings, including cash, short-term investments, accounts receivable, accounts payable, accrued wages and other employee costs, unearned revenue, and other accrued liabilities, the carrying value of the instruments and account groupings approximates fair value.
	The Financial Accounting Standards Board (the “FASB”) defines fair value as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy prioritizes the inputs utilized in measuring fair value as follows:
	•	Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date;
	•	Level 2—inputs other than the quoted prices in active markets that are observable for the asset or liability, either directly or indirectly; and
	•	Level 3—unobservable inputs for the asset or liability.
	The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including its short-term investments and marketable securities.
	Listed below are the Company's assets and liabilities, and their respective fair values, which were measured at fair value on a recurring basis as of December 31, 2014. The Company uses trading prices at the balance sheet date to determine the fair value of its assets measured on a recurring basis. The fair value of contingent consideration payable that was classified as Level 3 relates to probability assessments of expected future revenues related to the RTI Advanced Powder Materials acquisition. The contingent consideration is to be paid over the next ten years, and there is no limit to the potential amount of contingent consideration. The Company held no assets or liabilities measured at fair value on a recurring basis as of December 31, 2013. There were no transfers between levels during the year ended December 31, 2014.
			Quoted Market Prices			Significant Other Observable Inputs			Significant Unobservable Inputs			Fair Value
			(Level 1)			(Level 2)			(Level 3)
	Assets measured on a recurring basis as of December 31, 2014:
	Commercial paper		$	—		$	148,383		$	—		$	148,383
	Total		$	—		$	148,383		$	—		$	148,383
	Liabilities measured on a recurring basis as of December 31, 2014:
	Contingent consideration		$	—		$	—		$	1,000		$	1,000
	Total		$	—		$	—		$	1,000		$	1,000
	The fair value of contingent consideration was determined using a discounted cash flow model using a discount rate of 13.0%.
	As of both December 31, 2014 and 2013, the Company did not have any financial assets or liabilities that were measured at fair value on a non-recurring basis. Refer to discussions of intangible assets below for nonfinancial assets measured at fair value on a non-recurring basis.
	The carrying amounts and fair values of financial instruments for which the fair value option was not elected were as follows:
			31-Dec-14						31-Dec-13
			Carrying Amount			Fair Value			Carrying Amount			Fair Value
	Cash and cash equivalents		$	182,059		$	182,059		$	343,637		$	343,637
	Current portion of long-term debt		$	111,645		$	119,522		$	1,914		$	1,914
	Long-term debt		$	345,012		$	405,886		$	430,300		$	559,986
	The fair value of the current portion of long-term debt includes the $114,381 principal outstanding on the Company's 3.00% Convertible Senior Notes due 2015 (the “2015 Notes”). The fair value of long-term debt includes $402,500 aggregate principal amount 1.625% Convertible Senior Notes due 2019 (the “2019 Notes”) and is inclusive of the conversion feature, which was originally allocated for reporting purposes at $122.5 million, and is included in the Consolidated Balance Sheets within additional paid-in capital. The fair value of long-term debt was estimated based on significant observable inputs, including recent trades and trading levels of the outstanding debt on December 31, 2014 and 2013 (Level 2).
Cash and cash equivalents	Cash, cash equivalents and short-term investments:
	Cash and cash equivalents
	The Company considers all highly-liquid investments with an original maturity of three months or less to be cash equivalents. Cash equivalents principally consist of investments in short-term money market funds and corporate commercial paper.
	Available-for-sale securities
	Investments with maturities of less than one year are classified as available-for-sale, short-term investments and are recorded at fair value based on market quotes using the specific identification method, with unrealized gains and losses recorded as a component of accumulated other comprehensive loss until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identifications basis. The Company considers these investments to be available-for-sale as they may be sold to fund other investment opportunities as they arise.
	The major categories of the Company's cash equivalents and available-for-sale, short-term investments are as follows:
	Commercial paper
	The Company invests in high-quality commercial paper issued by highly-rated corporations and governments. By definition, the stated maturity on commercial paper obligations cannot exceed 270 days.
	Money market mutual funds
	The Company invests in money market mutual funds that seek to maintain a stable net asset value of $1.00, while limiting overall exposure to credit, market, and liquidity risks.
	Cash, cash equivalents, and short-term investments consisted of the following:
			December 31,			December 31,
			2014			2013
	Cash and cash equivalents:
	Cash		$	73,495		$	62,394
	Cash equivalents:
	Commercial paper		19,996			150,978
	Money market mutual funds		88,568			130,265
	Total cash and cash equivalents		182,059			343,637
	Short-term investments:
	Commercial paper		148,383			—
	Total short-term investments		148,383			—
	Total cash, cash equivalents, and short-term investments		$	330,442		$	343,637
	The Company had no short- or long-term investments at December 31, 2013. The Company's short-term investments at December 31, 2014 were as follows:
						Gross Unrealized
			Amortized Cost			Gains			Losses			Fair Value
	Commercial paper		$	148,447		$	—		$	64		$	148,383
	Total		$	148,447		$	—		$	64		$	148,383
	The Company typically purchases its available-for-sale debt securities either at a premium or a discount. The premium or discount is amortized over the remaining term of each security using the effective interest method. Amortization is recorded as either a decrement to interest income for premiums or an increment to interest income for discounts. For the year ended December 31, 2014, net amortization of premiums and discounts was immaterial.
	The Company classifies investments maturing within one year as short-term investments. Investments maturing in excess of one year are classified as noncurrent. All of the Company's investments had contractual maturities of less than one year at December 31, 2014.
	As of December 31, 2014, no investments classified as available-for-sale had been in a continuous unrealized loss position for greater than twelve months. The Company believes that the unrealized losses on the available-for-sale portfolio as of December 31, 2014 are temporary in nature and are related to market interest rate fluctuations and not indicative of a deterioration in the creditworthiness of the issuers.
Receivables	Receivables:
	Receivables are carried at net realizable value. Estimates are made as to the Company’s ability to collect outstanding receivables, taking into consideration the amount, the customer’s financial condition, and the age of the debt. The Company ascertains the net realizable value of amounts owed and provides an allowance when collection becomes doubtful. Receivables are expected to be collected in the normal course of business and consisted of the following:
			December 31,
			2014			2013
	Trade and commercial customers		$	118,439		$	106,091
	Less: Allowance for doubtful accounts		(694		)	(820		)
	Total receivables		$	117,745		$	105,271
Inventories	Inventories:
	Inventories are valued at cost as determined by the last-in, first-out (“LIFO”) method for approximately 55% and 56%, respectively, of the Company’s inventories as of December 31, 2014 and 2013. The remaining inventories are valued at cost determined by a combination of the first-in, first-out (“FIFO”) and weighted-average cost methods. Inventory costs generally include materials, labor, and manufacturing overhead (including depreciation). When market conditions indicate an excess of carrying cost over market value, a lower-of-cost-or-market provision is recorded. There were no LIFO decrements for the years ended December 31, 2014 or 2013.
	Inventories consisted of the following:
			December 31,
			2014			2013
	Raw materials and supplies		$	172,214		$	166,359
	Work-in-process and finished goods		332,573			314,438
	LIFO reserve		(30,481		)	(50,709		)
	Total inventories		$	474,306		$	430,088
Costs in excess of billings	Costs in excess of billings:
	As of December 31, 2014 and 2013, the Company had costs in excess of billings of $5,522 and $5,377, respectively. All $5,522 of costs in excess of billings are expected to be collected within the next twelve months. The Company had no claims included in inventory or progress payments netted against inventory at December 31, 2014 or 2013, respectively.
	Billings in excess of costs:
	As of December 31, 2014, the Company had billings in excess of costs of $9,962. All $9,962 of billings in excess of costs are expected to be recognized as revenue within the next twelve months. The Company had no billings in excess of costs at December 31, 2013.
Other current assets	Other current assets:
	The Company had other current assets of $19,803 and $16,947 at December 31, 2014 and 2013, respectively. Other current assets are comprised mainly of prepaid income taxes and other prepaid expenses which do not individually exceed five percent of consolidated current assets, and are expected to be realized within twelve months of the balance sheet date. The increase in other current assets in 2014 is attributable to an increase in prepaid income taxes.
Property, plant, and equipment	Property, plant, and equipment:
	The cost of property, plant, and equipment includes all direct costs of acquisition and capital improvements. Applicable amounts of interest on borrowings outstanding during the construction or acquisition period for major capital projects are capitalized. During the years ended December 31, 2014 and 2013, no interest expense was capitalized related to major capital expansion projects.
	Property, plant, and equipment is stated at cost and consisted of the following:
			December 31,
			2014			2013
	Land		$	18,778		$	18,769
	Buildings and improvements		117,646			117,225
	Machinery and equipment		471,691			446,787
	Computer hardware and software, furniture and fixtures, and other		70,378			65,622
	Construction-in-progress		53,566			52,546
			732,059			700,949
	Less: Accumulated depreciation		(362,772		)	(328,609		)
	Total property, plant, and equipment, net		$	369,287		$	372,340
	Depreciation is determined using the straight-line method over the estimated useful lives of the various classes of assets. Depreciation expense for the years ended December 31, 2014, 2013, and 2012 was $40,041, $39,439, and $37,364, respectively. Depreciation is generally recorded over the following useful lives:
	Buildings and improvements		20-40 years
	Machinery and equipment		7-15 years
	Furniture and fixtures		5-10 years
	Computer hardware and software		3-10 years
	The cost of properties retired or otherwise disposed of, together with the accumulated depreciation provided thereon, is eliminated from the accounts. The net gain or loss is recognized as a component of operating income.
	Leased equipment under capital leases are amortized using the straight-line method over the term of the lease or the estimated useful life of the equipment depending on the terms of the lease contract.
	Routine maintenance, repairs, and replacements are charged to operations. Expenditures that materially increase values, change capacities, or extend useful lives are capitalized.
Goodwill and intangible assets	Goodwill and intangible assets:
	In the case of goodwill and intangible assets, if product demand or market conditions reduce management’s expectation of future cash flows from these assets, a write-down of the carrying value or acceleration of the amortization period may be required. Intangible assets were originally valued at fair value at the date of acquisition.
	Goodwill. The Company performs its goodwill impairment testing at the reporting unit level. The Company’s four reporting units, which are one level below its operating segments, where appropriate, are as follows: 1) the Titanium reporting unit; 2) the Fabrication reporting unit; 3) the Medical Device Fabrication reporting unit; and 4) the Energy Fabrication reporting unit. As of December 31, 2014 and 2013, the Energy Fabrication reporting unit had no goodwill.
	The carrying value of goodwill at the Company’s four reporting units as of the Company’s October 1, 2014 annual impairment test was as follows:
		Goodwill
	Titanium reporting unit	$	24,016
	Fabrication reporting unit	76,645
	Medical Device Fabrication reporting unit	44,789
	Energy Fabrication reporting unit	—
	Total Goodwill	$	145,450
	Goodwill is tested annually during the fourth quarter and is assessed between annual tests if an event occurs or circumstances change that would indicate the carrying value of a reporting unit may exceed its fair value. These events and circumstances may include, but are not limited to: significant adverse changes in the business climate or legal factors; an adverse action or assessment by a regulator; unanticipated competition; a material negative change in relationships with significant customers; strategic decisions made in response to economic or competitive conditions; loss of key personnel; or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed.
	The fair value of the Company’s four reporting units is calculated by averaging the fair values determined using an income approach (i.e., a discounted cash flow model) and a market approach. A discounted cash flow model is based on historical and projected financial information and provides a fair value estimate based upon each reporting unit’s long-term operating and cash flow performance. This approach also considers the impact of cyclical downturns that occur in the titanium and aerospace industries. The market valuation approach applies market multiples, such as EBITDA and revenue multiples, developed from a set of peer group companies to each reporting unit to determine its fair value. The Company considered the use of a cost approach but determined such an approach was not appropriate.
	Utilizing a discounted cash flow model, the Company estimates its cash flow projections using business and economic data available at the time the projection is calculated. A significant number of assumptions and estimates are involved in the application of the discounted cash flow model to forecast operating cash flows, including overall business conditions, sales volumes and prices, costs of production, and working capital changes. The Company considers historical experience and available information at the time the reporting units’ fair values are estimated. Discount rates were developed using a Weighted-Average Cost of Capital (“WACC”) methodology. The WACC represents the blended average required rate of return for equity and debt capital based on observed market return data and reporting unit specific risk factors.
	The discount rates used in the Company’s October 1, 2014 annual impairment test were as follows:
	Titanium reporting unit	11	%
	Fabrication reporting unit	11.5	%
	Medical Device Fabrication reporting unit	12	%
	The Company performed a two-step impairment test for all reporting units with a goodwill balance as of the testing date. Step one of the goodwill impairment test indicated that the fair value of the Titanium and Fabrication reporting units each exceeded their respective carrying values by a significant margin, while the Medical Device Fabrication reporting unit’s fair value exceeded its carrying value by approximately 14% as of the testing date. As all reporting units' fair values exceeded their book values, step two was not required.
	Excluding the Energy Fabrication reporting unit, whose goodwill was fully impaired in 2009, and the $13,959 impairment at the Medical Device Fabrication reporting unit in 2013, there have been no other impairments to date at the Company’s reporting units. Uncertainties or other factors that could result in a potential impairment in future periods may include any cancellation of or material modification to one of the major aerospace programs the Company currently supplies, including the Joint Strike Fighter program, the Boeing 787 program, or the Airbus family of aircraft, including the A350 XWB, A320neo, or A380 programs. In addition, the Company’s ability to maintain profitability of these programs may also impact the results of a future impairment test. Furthermore, additional pricing pressures and regulatory requirements or other impacts from the Patient Protection and Affordable Care Act could result in an additional goodwill impairment at the Medical Device Fabrication reporting unit.
	The carrying amount of goodwill attributable to each segment at December 31, 2012, 2013, and 2014 was as follows:
			Titanium Segment			Engineered Products and Services Segment			Total
	31-Dec-12		$	9,662		$	120,590		$	130,252
	Additions		—			2,185			2,185
	Impairments		—			(13,959		)	(13,959		)
	Translation adjustment		—			(900		)	(900		)
	31-Dec-13		9,662			107,916			117,578
	Additions (Note 4)		14,211			14,712			28,923
	Purchase price allocation adjustment		—			100			100
	Translation adjustment		—			(1,083		)	(1,083		)
	Balance at December 31, 2014		$	23,873		$	121,645		$	145,518
	At both December 31, 2014 and 2013, the EP&S Segment had accumulated goodwill impairment losses of $22,858, while the Titanium Segment has no accumulated impairment losses, other than those relating to discontinued operations, not included in the table above.
	Intangible assets.    Intangible assets consist primarily of customer relationships, trade names, and developed technology acquired through various business combinations. These intangible assets were valued at fair value at acquisition. In the event that long-term demand or market conditions change and the expected future cash flows associated with these assets is reduced, a write-down or acceleration of the amortization period may be required. The Company has two indefinite-lived intangible assets, the Remmele trade name and the Directed Manufacturing trade name, which it does not amortize. The Company currently intends to utilize the Remmele and Directed Manufacturing trade names indefinitely. Other intangible assets are being amortized over the following periods:
	Customer relationships	7-20 years
	Developed technology	7-20 years
	Backlog	0.5-2 years
	Amortization expense was $4,835, $4,386, $3,760, for the years ended December 31, 2014, 2013, and 2012, respectively. Estimated annual amortization expense expected in each of the next five successive years is as follows:
		Amortization
	2015	$	5,089
	2016	$	5,047
	2017	$	5,047

Management evaluates the recoverability of indefinite-lived intangible assets other than goodwill annually by using a discounted cash flow analysis based on historical and projected financial information, and assesses the recoverability of indefinite-lived intangible assets between annual tests if an event occurs or circumstances change that would indicate the carrying value of an indefinite-lived intangible asset may exceed its fair value. Several assumptions and estimates are involved in the application of the discounted cash flow model to forecast revenues, royalty rates, income tax rates, and discount rates. As of October 1, 2014, the Company’s only indefinite-lived intangible assets other than goodwill were the Remmele and Directed Manufacturing trade names. Two-step impairment analyses of the Remmele and Directed Manufacturing trade name intangible assets were performed. In each case, a fair value in excess of carrying value was determined in step one of the test, thus step two was not required. The fair values of the Remmele and Directed Manufacturing trade names were determined using a discounted cash flow model (Level 3) utilizing discount rates ranging from 12.5%-13.0%.
Other long-lived assets	Other long-lived assets:
	The Company evaluates the potential impairment of other long-lived assets including property, plant, and equipment and amortizable intangible assets when events or circumstances indicate that a change in value may have occurred. If the carrying value of the asset groupings exceeds the sum of the undiscounted expected future cash flows, the carrying value of the asset is written down to fair value. No such impairments were recorded during 2014.
Other non-current assets	Other non-current assets:
	The Company had other non-current assets of $15,317 and $23,247 at December 31, 2014 and 2013, respectively. Other non-current assets are comprised mainly of deferred financing costs and deferred engineering costs, and are not expected to be realized within twelve months of the balance sheet date. The decrease in other non-current assets in 2014 is primarily attributable to the change in funded status of the Company's pension plans and the amortization of deferred financing fees of $1,890.
Environmental	Environmental:
	The Company expenses environmental costs related to potential liabilities arising in the course of business and the remediation of those liabilities. The Company determines its liability for remediation on a site-by-site basis and records a liability when it is probable and can be reasonably estimated. The estimated liability of the Company is not discounted or reduced for possible recoveries from insurance carriers.
Treasury stock	Treasury stock:
	The Company accounts for treasury stock under the cost method and includes such shares as a reduction of total shareholders’ equity.
Revenue Recognition	Revenue Recognition:
	Product and service revenues are recognized when persuasive evidence of an arrangement exists, product delivery has occurred or services have been rendered, pricing is fixed or determinable, and collection is reasonably assured. Service revenues are recognized as services are rendered.
	Revenues under long-term construction-type contracts are recorded on a percentage-of-completion method measured on the cost-to-cost basis and the units-of-delivery basis. Prior to 2014, revenues and costs under contracts measured on the cost-to-cost method were recorded using the zero profit method under the Financial Accounting Standards Board's (the "FASB") Accounting Standards Codification ("ASC") 605-35 until the period when the Company believed it was able to estimate the total contract revenues and costs, at which point the cumulative contract gross profit earned to date was recorded. This generally occurred commensurate with the primary product under the contract being delivered. During 2014, the Company implemented a rigorous process for estimating total contract costs and revenues for all outstanding and future projects accounted for under ASC 605-35. As a result, for the majority of the Company’s contracts accounted for under ASC 605-35, the Company now recognizes costs, revenues, and related gross profit as it completes work on these projects, rather than using the zero profit method. For certain of its contracts, the full scope of work may be ill-defined at the time progress towards completion begins. For these contracts, the Company utilizes the zero profit method until such time as the full scope of the contract is defined and estimates of total costs and revenues can be determined.
	Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident. No such losses have been recorded at December 31, 2014, 2013, or 2012.
	Revenues from contracts with multiple element arrangements are recognized as each element is earned based on the relative fair value of each element provided the delivered elements have value to customers on a standalone basis. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price for the product or service when it is sold separately.
	Value added taxes collected on sales are excluded from revenue and recorded as a liability on the Consolidated Balance Sheet until remitted to the taxing authority.
Shipping and handling fees and costs	Shipping and handling fees and costs:
	All amounts billed to a customer in a sales transaction related to shipping and handling represent revenues earned and are reported as revenue. Costs incurred by the Company for shipping and handling, including transportation costs paid to third-party shippers, are reported as a component of cost of sales. Shipping and handling expenses were immaterial for the years ended December 31, 2014, 2013, and 2012, respectively.
Research and development	Research and development:
	Research and development costs are expensed as incurred. These costs totaled $4,613, $3,931, and $4,164, for the years ended December 31, 2014, 2013, and 2012, respectively, and typically include employment costs, material costs, contractor fees, and other administrative costs.
Pensions	Pensions:
	The Company provides defined benefit pension plans for certain of its salaried and represented workforce. Benefits for its salaried participants are generally based on participants’ years of service and compensation. Benefits for represented pension participants are generally determined based on an amount for years of service. Other employees participate in 401(k) plans whereby the Company may provide a match of employee contributions. A portion of the employees in the Titanium Segment are covered by defined benefit plans in which benefits are based on years of service and annual compensation. Contributions to the defined benefit plans, as determined by an independent actuary in accordance with applicable regulations, provide not only for benefits attributed to date, but also for those expected to be earned in the future. The Company’s policy is to fund pension costs at amounts equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended, for U.S. plans plus additional amounts as may be approved from time to time.
	The Company accounts for its defined benefit pension plans in accordance with the FASB’s authoritative guidance, which requires amounts recognized in the financial statements to be determined on an actuarial basis, rather than as contributions are made to the plans, and requires recognition of the funded status of the Company’s plans in its Consolidated Balance Sheet. In addition, it also requires actuarial gains and losses, prior service costs and credits, and transition obligations that have not yet been recognized to be recorded as a component of accumulated other comprehensive loss.
Other post-retirement benefits	Other post-retirement benefits:
	The Company provides health care benefits and life insurance coverage for certain of its employees and their dependents. Under the Company’s current plans, certain of the Company’s employees will become eligible for those benefits if they reach retirement age while working with the Company. In general, employees of the Titanium Segment are covered by post-retirement health care and life insurance benefits.
	The Company also sponsors another post-retirement plan covering certain employees. This plan provides health care benefits for eligible employees. These benefits are accounted for on an actuarial basis, rather than as benefits are paid. The Company does not pre-fund post-retirement benefit costs, but rather pays claims as billed.
Income taxes	Income taxes:
	Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities multiplied by the enacted tax rates which will be in effect when these differences are expected to reverse. In addition, deferred tax assets may arise from net operating losses (“NOLs”) and tax credits which may be carried back to obtain refunds or carried forward to offset future cash tax liabilities.
	On a quarterly basis, the Company evaluates the available evidence supporting the realization of deferred tax assets and makes adjustments for a valuation allowance, as necessary.
	Tax benefits related to uncertain tax provisions taken or expected to be taken on a tax return are recorded when such benefits meet a more-likely-than-not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that either the appropriate taxing authority has completed their examination even though the statute of limitations remains open, or the statute of limitation has expired. Interest and penalties related to uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized.
Foreign currencies	Foreign currencies:
	For the Company’s foreign subsidiaries in the United Kingdom and France, whose functional currency is the U.S. dollar, monetary assets and liabilities are remeasured at current rates, non-monetary assets and liabilities are remeasured at historical rates, and revenues and expenses are translated at average rates on a monthly basis throughout the year. Resulting differences from the remeasurement process are recognized in income and reported as other income (expense).
	The functional currency of the Company’s Canadian subsidiary is the Canadian dollar. Assets and liabilities are translated at period-end exchange rates. Income statement accounts are translated at the average rates of exchange prevailing during the year. Translation adjustments are reported as a component of accumulated other comprehensive loss in shareholders’ equity and are included in comprehensive income (loss).
	Transactions and balances denominated in currencies other than the functional currency of the transacting entity are remeasured at current rates when the transaction occurs and at each balance sheet date. Transaction gains and losses are included in net income for the period.
Accumulated other comprehensive income (loss)	Accumulated other comprehensive loss:
	The components of accumulated other comprehensive loss, net of tax, on the Company’s Consolidated Balance sheet at December 31, 2014 and 2013 were as follows:
			Foreign Currency Translation			Actuarial Losses on Benefit Plans			Investment Activity			Total
	Accumulated other comprehensive loss at December 31, 2011		$	10,793		$	(49,635	)	$	(8	)	$	(38,850	)

	Balance at December 31, 2013		$	5,780		$	(46,177	)	$	—		$	(40,397	)
	Other comprehensive loss before reclassifications, net of tax		(9,733		)	(9,852		)	(41		)	(19,626		)

	Accumulated other comprehensive loss at December 31, 2014		$	(3,953	)	$	(51,595	)	$	(41	)	$	(55,589	)
	Amounts reclassified from accumulated other comprehensive loss, net of tax, for December 31, 2014 are presented below. These amounts are reclassified to Cost of sales and Selling, general, and administrative expenses within the Consolidated Statement of Operations.
			31-Dec-14			31-Dec-13
	Impact of Defined Benefit Pension Items
	Actuarial losses and prior service costs		$	7,122		$	8,435
	Special termination benefits		—			3,196
	Tax expense		(2,688		)	(4,360		)
	Total reclassifications		$	4,434		$	7,271
	Refer to Note 8 of these Consolidated Financial Statements for further information about the Company’s benefit plans.
Stock-based compensation	Stock-based compensation:
	The Company utilizes a “graded vesting” approach to recognize compensation expense over the vesting period of stock awards. For employees who have reached retirement age, the Company recognizes compensation expense at the date of grant. For employees approaching retirement eligibility, the Company amortizes compensation expense over the period from the grant date through the retirement eligibility date.
	Cash flows resulting from the windfall tax benefits from tax deductions in excess of the compensation cost recognized (“excess tax benefits”) are classified as financing cash inflows. For the years ended December 31, 2014, 2013, and 2012, operating cash flows were decreased and financing cash flows were increased by $199, $552, and $196, respectively.
	Total compensation expense recognized in the Consolidated Statements of Operations for stock-based compensation arrangements was $5,670, $6,026, and $4,797 for the years ended December 31, 2014, 2013, and 2012, respectively. The total income tax benefit recognized in the Consolidated Statements of Operations for stock-based compensation arrangements was $1,361, $1,886, and $1,727 for the years ended December 31, 2014, 2013, and 2012, respectively. There was no stock-based compensation cost capitalized for the years ended December 31, 2014, 2013, and 2012.
New Accounting Standards	New Accounting Standards:
	In January 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2015-01, "Income Statement - Extraordinary and Unusual Items." This ASU eliminates from U.S. GAAP the concept of extraordinary items. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
	In November 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2014-17, "Pushdown Accounting." This ASU provides an acquired entity with the option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. This ASU is effective as of November 18, 2014. The adoption of this ASU did not have a material impact on the Company's Consolidated Financial Statements.
	In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements—Going Concern—Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern." The amendment requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. The guidance is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
	In June 2014, the FASB issued ASU 2014-12, "Compensation—Stock Compensation—Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendment requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early application is permitted. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
	In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This ASU prescribes that an entity should recognize revenue to depict the transfer of promised 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 amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and can be adopted by the Company using either a full retrospective or modified retrospective approach. Early application is not permitted. The Company is currently evaluating the impact of the adoption of this ASU on the Company's Consolidated Financial Statements.
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements and Property, Plant, and Equipment—Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." This ASU amends the requirements for reporting discontinued operations to include only disposals of a component or groups of components of an entity if the disposal represents a strategic shift that has or will have a major effect on the entity’s operations and financial results. The amendment requires additional disclosure regarding disposals that meet the criteria for discontinued operations in the ASU, and is effective for all disposals within annual and interim periods beginning on or after December 15, 2014. Early adoption is permitted for disposals that have not been reported in financial statements previously issued. The Company does not expect that the adoption of the ASU will have a material impact on the Company's Consolidated Financial Statements.
	In July 2013, the FASB issued ASU 2013-11, "Income Taxes—Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." This ASU prescribes the Balance Sheet presentation for unrecognized tax benefits in the presence of a net operating loss carryforward, tax loss or tax credit carryforward. The amendments in the ASU do not require any new recurring disclosures, and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.
	In March 2013, the FASB issued ASU 2013-05, "Foreign Currency Matters—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU clarifies the applicable guidance for the release of the cumulative translation adjustment under current U.S. GAAP. The amendments in this ASU are effective prospectively for annual and interim reporting periods beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.
	In February 2013, the FASB issued ASU 2013-04, "Liabilities—Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date." This ASU provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the ASU is fixed at the reporting date. The amendments in this ASU are effective prospectively for annual and interim reporting periods beginning after December 15, 2013. The adoption of this guidance during 2014 did not have a material impact on the Company's Consolidated Financial Statements.

-1	Intercompany investments include equity investments and intercompany loans receivable from legal entities not included within the same consolidation.
-2	The Condensed Consolidating Balance sheet has been adjusted to correct the prior presentation of intercompany debt and investment balances. Previously, certain intercompany debt and investment balances had been netted, resulting in the understatement of total assets and liabilities of both the Guarantor Subsidiaries and Non-Guarantor Subsidiaries, as well as understatement of Guarantor Subsidiaries Shareholders’ Equity. These adjustments increased (decreased) intercompany investments by $82,070, $103,917, and $(185,987); intercompany debt by $44,970, $103,917, and $(148,887); and shareholders’ equity by $37,100, $0, and $(37,100) for Guarantor Subsidiaries, Non-Guarantor Subsidiaries, and Eliminations, respectively.
