Basis of Presentation: In management’s opinion, the accompanying consolidated financial statements of Materion Corporation and its subsidiaries (referred to herein as the Company, our, we, or us) contain all of the adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods reported. All adjustments were of a normal and recurring nature. Certain amounts in prior periods have been reclassified to conform to the 2018 consolidated financial statement presentation.

These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's 2017 Annual Report on Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year.
New Pronouncements Adopted: In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires an employer to report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by pertinent employees during the period. This ASU requires non-service cost components of net benefit cost to be presented in a caption below the Company's Operating profit and allows only the service cost component to be eligible for capitalization. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those periods, with early adoption permitted. The Company adopted the new standard as of January 1, 2018 and applied its amendments retrospectively for the presentation of service cost and other components of net benefit cost on the income statement and prospectively for the capitalization of service cost and net periodic postretirement benefits in assets. The application of ASU 2017-07 resulted in an increase to Operating profit of $0.4 million and $1.0 million for the third quarter and first nine months of 2017, respectively, which was offset by a corresponding increase in Other non-operating expense, net. The adoption of this ASU did not have a material effect on the Company's financial condition or liquidity. The Company utilized this ASU's practical expedient, which permits the Company to use the amounts disclosed in its Pensions and Other Post-employment Benefits note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), which supersedes previous revenue recognition guidance. The Company adopted the new standard using the modified retrospective method as of January 1, 2018. Prior periods were not retrospectively adjusted. This approach was applied to all contracts not completed as of January 1, 2018. The new standard primarily impacted the Company's timing of revenue recognition for certain contracts and subcontracts with the United States (U.S.) government that contain termination for convenience clauses, and due to the cumulative impact of adopting ASC 606, the Company recorded a reduction to beginning retained earnings of $0.4 million, net of tax as summarized below:

The adoption of the standard did not have a material impact to the Company's consolidated financial statements. Refer to Note B for additional disclosures relating to ASC 606.
New Pronouncements Issued: In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends and simplifies existing guidance to allow companies to more accurately present the economic effects of risk management activities in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases, which eliminates the off-balance-sheet accounting for leases. The new guidance will require lessees to report their operating leases as both an asset and liability on the balance sheet and disclose key information about leasing arrangements. This ASU is required to be applied using a modified retrospective adoption method with the option of applying the guidance either retrospectively to each prior comparative reporting period presented or retrospectively at the beginning of the period of adoption. Early adoption is permitted. The Company will adopt this ASU on January 1, 2019 and will apply it retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment to retained earnings. The Company will elect to apply the practical expedients that do not require reassessment of existing contracts for embedded leases or to reassess lease classification or initial direct costs. In preparation for the adoption, the Company, along with an outside consultant, has executed on its project plan to identify a complete lease population, analyze lease agreements, and evaluate technology solutions. The Company selected and began implementing a new lease management system during the third quarter of 2018. Once the transition to the new system is completed, this software will enable us to quantify the full impact this ASU will have on our consolidated financial statements.
No other recently issued or effective ASUs had, or are expected to have, a material effect on the Company's results of operations, financial condition, or liquidity.

Revenue Recognition

Revenue from Contract with Customer [Abstract]  
Revenue from Contract with Customer [Text Block]
Revenue Recognition

Net sales consist primarily of revenue from the sale of precious and non-precious specialty metals, beryllium and copper-based alloys, beryllium composites, and other products into numerous end markets. The Company requires an agreement with a customer that creates enforceable rights and performance obligations. The Company generally recognizes revenue, in an amount that reflects the consideration to which it expects to be entitled, upon satisfaction of a performance obligation by transferring control over a product to the customer. Control over the product is generally transferred to the customer when the Company has a present right to payment, the customer has legal title, the customer has physical possession, the customer has the significant risks and rewards of ownership, and/or the customer has accepted the product.

Shipping and Handling Costs: The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill our promise to transfer the associated products. Accordingly, customer payments of shipping and handling costs are recorded as a component of net sales, and related costs are recorded as a component of cost of sales.

Taxes Collected from Customers and Remitted to Governmental Authorities: Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Product Warranty: Substantially all of the Company’s customer contracts contain a warranty that provides assurance that the purchased product will function as expected and in accordance with certain specifications. The warranty is intended to safeguard the customer against existing defects and does not provide any incremental service to the customer.

Transaction Price Allocated to Future Performance Obligations: ASC 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied at September 28, 2018. Remaining performance obligations include noncancelable purchase orders and customer contracts. The guidance provides certain practical expedients that limit this requirement. As such, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. After considering the practical expedient, at September 28, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $33.0 million, of which $4.0 million will be recognized in 2018.

Contract Costs: The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs primarily relate to sales commissions, which are included in selling, general, and administrative expenses.
Contract Balances: The timing of revenue recognition, billings and cash collections resulted in the following contract assets and contract liabilities:

Accounts receivable, trade represents payments due from customers relating to the transfer of the Company’s products and services. The Company believes that its receivables are collectible and appropriate allowances for doubtful accounts have been recorded. Impairment losses (bad debt) incurred relating to our receivables were immaterial during the third quarter and first nine months of 2018.

Unbilled receivables represent expenditures on contracts, plus applicable profit margin, not yet billed. Unbilled receivables are normally billed and collected within one year. Billings made on contracts are recorded as a reduction of unbilled receivables.

Unearned revenue is recorded for consideration received from customers in advance of satisfaction of the related performance obligations.

As a practical expedient, the Company does not adjust the promised amount of consideration for the effects of a significant financing component because the period between the transfer of a product or service to a customer and when the customer pays for that product or service will be one year or less. The Company does not include extended payment terms in its contracts with customers.

Income Tax Disclosure [Abstract]  
Income Taxes
Income Taxes
On December 22, 2017, the Tax Cuts and Jobs Act (TCJA) was signed into law. The TCJA includes a number of provisions, including: (1) the lowering of the U.S. corporate tax rate from 35% to 21%; (2) elimination of the corporate alternative minimum tax (AMT); (3) the creation of the base erosion anti-abuse tax (BEAT, a new minimum tax); (4) a general elimination of the U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income (GILTI), which allows for the possibility of using foreign tax credits (FTCs) and a deduction of up to 50% to offset the income tax liability (subject to some limitations); (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; and (8) limitations on the deductibility of certain executive compensation.

The Company recorded an income tax benefit of $2.7 million in the third quarter of 2018, resulting in an effective tax rate of (15.7)% against income before income taxes, and income tax expense of $1.7 million in the third quarter of 2017, resulting in an effective tax rate of 15.5% against income before income taxes.

In the first nine months of 2018, income tax expense of $1.7 million was calculated using an effective tax rate of 4.0%, while income tax expense of $3.3 million in the first nine months of 2017 was calculated using an effective tax rate of 14.4%.

In the third quarter and first nine months of 2018, income tax expense differed from the U.S. Federal statutory income tax rate of 21% primarily due to the impact of foreign losses in jurisdictions that will not result in tax benefits, percentage depletion, the U.S. research and development credit, the new GILTI income inclusion, the new executive compensation limitations, and discrete income tax benefits of $6.1 million and $7.1 million recorded in the third quarter and first nine months of 2018, respectively. The $6.1 million of discrete income tax benefits recorded in the third quarter of 2018 were comprised of a $7.4 million benefit for the partial reversal of a $9.5 million valuation allowance related to foreign tax credits that were deemed unrealizable as of December 31, 2017, and a $2.4 million benefit for the re-measurement of certain deferred tax assets and liabilities. These benefits were offset by $2.2 million of expense for a valuation allowance related to deferred tax assets that are not likely to be realized for one of the Company's controlled foreign corporations, and a $1.5 million 2017 U.S. Federal income tax return to provision expense adjustment. The $1.0 million discrete income tax benefit recorded in the first six months of 2018 consisted of $0.4 million of excess tax benefits related to share based payment transactions and a $0.6 million benefit attributable to the re-measurement of certain deferred tax assets and liabilities. The Company does not expect to incur a new BEAT minimum tax or an interest expense limitation.

In the third quarter and first nine months of 2017, income tax expense differed from the U.S Federal statutory income tax rate of 35% primarily due to the impact of percentage depletion, foreign rate differential, the U.S. research and development credit, and discrete income tax benefits of $0.5 million and $1.3 million, respectively, related to the reversal of uncertain tax positions due to a lapse in the statute of limitations and the adoption of ASU 2016-09, Improvements to Employee Share-based Payment Accounting.

As disclosed in Note G - Income Taxes in the Company's 2017 Annual Report on Form 10-K, the Company was able to reasonably estimate certain TCJA effects and, therefore, recorded provisional adjustments associated with the deemed repatriation transition tax and remeasurement of certain deferred tax asset and liabilities. As of the third quarter of 2018, the Company recorded a measurement period tax expense adjustment of $1.2 million related to the transition tax and a $2.4 million tax benefit related to the re-measurement of certain deferred tax assets and liabilities. The Company’s accounting for the income tax effects of the TCJA continue to be provisional and the company expects to record the final measurement period adjustment in the fourth quarter of 2018.

The Company continues to refine the additional measurement-period adjustments related to the transition tax post September 30, 2018 because the total post 1986 earnings and profits (E&P) for its foreign subsidiaries has not yet been completed. The Company is continuing to gather additional information and will complete its accounting for these items in the fourth quarter of 2018. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations.

The Company was able to reasonably estimate the remeasurement of certain deferred tax asset and liabilities at an initial provisional amount of $5.0 million of additional income tax expense for the year ended December 31, 2017. The Company made refinements to the calculation during 2018, primarily as a result of information gathered during the preparation of the 2017 U.S. Federal income tax return, leaving a remaining provisional amount of $2.0 million at the end of the third quarter of 2018. The Company is continuing to gather additional information and expects to complete its accounting for these items in the fourth quarter of 2018.

Due to the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the TCJA and the application of the Accounting Standards Codification 740, Income Taxes. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the period cost method) or (2) factoring such amounts into the Company's measurement of its deferred taxes (the deferred method). The Company's selection of an accounting policy related to the new GILTI tax rules will depend on a number of different aspects of the estimated long-term effects of this provision under the TCJA. Therefore, the Company has not recorded any potential deferred tax effects related to the GILTI in the financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI or use the period cost method. However, the Company has included an estimate of the 2018 current GILTI impact in the annual effective tax rate for 2018.

Stock-based Compensation Expense
Stock-based Compensation Expense
Stock-based compensation expense, which includes awards settled in shares and in cash, was $4.2 million and $9.4 million in the third quarter and first nine months of 2018, respectively, compared to $1.5 million and $6.2 million in the same periods of 2017.
The Company granted 65,112 stock appreciation rights (SARs) to certain employees during the first nine months of 2018. The weighted-average exercise price per share and weighted-average fair value per share of the SARs granted during the nine months ended September 28, 2018 were $50.35 and $15.73, respectively. The Company estimated the fair value of the SARs using the following weighted-average assumptions in the Black-Scholes model:
Risk-free interest rate
 
2.58
%
Dividend yield
 
0.8
%
Volatility
 
31.9
%
Expected term (in years)

The Company granted 59,222 stock-settled restricted stock units (RSUs) to certain employees and 14,728 stock-settled RSUs to non-employee directors during the first nine months of 2018. The Company measures the fair value of stock-settled RSUs based on the closing market price of a share of Materion common stock on the date of the grant. The weighted-average fair value per share was $50.35 and $51.60 for stock-settled RSUs granted to employees and non-employee directors, respectively, during the nine months ended September 28, 2018. RSUs are expensed over the vesting period of three years for employees and one year for non-employee directors.
The Company granted stock-settled performance-based restricted stock units (PRSUs) to certain employees in the first nine months of 2018. The weighted-average fair value of the stock-settled PRSUs was $50.35 per share and will be expensed over the vesting period of three years. The final payout to the employees for all PRSUs will be based upon the Company’s return on invested capital and the total return to shareholders over the vesting period relative to a peer group’s performance over the same period.
At September 28, 2018, unearned compensation cost related to the unvested portion of all stock-based awards was approximately $9.2 million, and is expected to be recognized over the remaining vesting period of the respective grants.

Fair Value of Financial Instruments
Fair Value of Financial Instruments
The Company measures and records financial instruments at fair value. A fair value hierarchy is used for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three levels:
Level 1 — Quoted market prices in active markets for identical assets and liabilities;
Level 2 — Inputs other than Level 1 inputs that are either directly or indirectly observable; and
Level 3 — Unobservable inputs developed using estimates and assumptions developed by the Company, which reflect those that a market participant would use.

The Company uses a market approach to value the assets and liabilities for financial instruments in the table above. Outstanding contracts are valued through models that utilize market observable inputs, including both spot and forward prices, for the same underlying currencies and metals. The carrying values of the other working capital items and debt in the Consolidated Balance Sheets approximate fair values as of September 28, 2018 and December 31, 2017.

Derivative Instruments and Hedging Activity

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivative Instruments and Hedging Activity
Derivative Instruments and Hedging Activity
The Company uses derivative contracts to hedge portions of its foreign currency exposures and uses derivatives to hedge a portion of its precious metal exposures. The objectives and strategies for using derivatives in these areas are as follows:
Foreign Currency.    The Company sells a portion of its products to overseas customers in their local currencies, primarily the euro and yen. The Company secures foreign currency derivatives, mainly forward contracts and options, to hedge these anticipated sales transactions. The purpose of the hedge program is to protect against the reduction in the dollar value of foreign currency sales from adverse exchange rate movements. Should the dollar strengthen significantly, the decrease in the translated value of the foreign currency sales should be partially offset by gains on the hedge contracts. Depending upon the methods used, hedge contracts may limit the benefits from a weakening U.S. dollar.
The use of forward contracts locks in a firm rate and eliminates any downside risk from an adverse rate movement as well as any benefit from a favorable rate movement. The Company may from time to time choose to hedge with options or a tandem of options, known as a collar. These hedging techniques can limit or eliminate the downside risk but can allow for some or all of the benefit from a favorable rate movement to be realized. Unlike a forward contract, a premium is paid for an option; collars, which are a combination of a put and call option, may have a net premium but can be structured to be cash neutral. The Company will primarily hedge with forward contracts due to the relationship between the cash outlay and the level of risk.
The use of foreign currency derivative contracts is governed by policies approved by the Audit Committee of the Board of Directors. A team consisting of senior financial managers reviews the estimated exposure levels, as defined by budgets, forecasts, and other internal data, and determines the timing, amounts, and instruments to use to hedge that exposure within the confines of the policy. Management analyzes the effective hedged rates and the actual and projected gains and losses on the hedging transactions against the program objectives, targeted rates, and levels of risk assumed. Hedge contracts are typically layered in at different times for a specified exposure period in order to minimize the impact of rate movements.
Precious Metals.    The Company maintains the majority of its precious metal production requirements on consignment in order to reduce its working capital investment and the exposure to metal price movements. When a precious metal product is fabricated and ready for shipment to the customer, the metal is purchased out of consignment at the current market price. The price paid by the Company forms the basis for the price charged to the customer. This methodology allows for changes in either direction in the market prices of the precious metals used by the Company to be passed through to the customer, and reduces the impact changes in prices could have on the Company's margins and operating profit. The consigned metal is owned by financial institutions that charge the Company a financing fee based upon the current value of the metal on hand.
In certain instances, a customer may want to establish the price for the precious metal at the time the sales order is placed rather than at the time of shipment. Setting the sales price at a different date than when the material would be purchased potentially creates an exposure to movements in the market price of the metal. Therefore, in these limited situations, the Company may elect to enter into a forward contract to purchase precious metal. The forward contract allows the Company to purchase metal at a fixed price on a specific future date. The price in the forward contract serves as the basis for the price to be charged to the customer. By doing so, the selling price and purchase price are matched, and the Company's price exposure is reduced.
The Company refines precious metal-containing materials for its customers and typically will purchase the refined metal from the customer at current market prices. In limited circumstances, the customer may want to fix the price to be paid at the time of the order as opposed to when the material is refined. The customer may also want to fix the price for a set period of time. The Company may then elect to enter into a hedge contract, either a forward contract or a swap, to fix the price for the estimated quantity of metal to be purchased, thereby reducing the exposure to adverse movements in the price of the metal.
In certain circumstances, the Company also refines metal from the customer and may retain a portion of the refined metal as payment. The Company may elect to enter into a forward contract to sell precious metal to reduce the Company's price exposure.
The Company may from time to time elect to purchase precious metal and hold in inventory rather than on consignment due to potential credit line limitations or other factors. These purchases are typically held for a short duration. A forward contract will be secured at the time of the purchase to fix the price to be used when the metal is transferred back to the consignment line, thereby limiting any price exposure during the time when the metal was owned.
The Company will only enter into a derivative contract if there is an underlying identified exposure. Contracts are typically held until maturity. The Company does not engage in derivative trading activities and does not use derivatives for speculative purposes. The Company only uses currency hedge contracts that are denominated in the same currency as the underlying exposure and precious metal hedge contracts denominated in the same metal as the underlying exposure.
All derivatives are recorded on the balance sheet at fair value. If the derivative is designated and effective as a cash flow hedge, changes in the fair value of the derivative are recognized in other comprehensive income (OCI) until the hedged item is recognized in earnings. The ineffective portion of a derivative’s fair value, if any, is recognized in earnings immediately. If a derivative is not a hedge, changes in the fair value are adjusted through income. The fair values of the outstanding derivatives are recorded on the balance sheet as assets (if the derivatives are in a gain position) or liabilities (if the derivatives are in a loss position). The fair values will also be classified as short-term or long-term depending upon their maturity dates.
The following table summarizes the notional amount and the fair value of the Company’s outstanding derivatives not designated as hedging instruments and balance sheet classification as of September 28, 2018 and December 31, 2017:

All of these contracts were designated and effective as cash flow hedges. No ineffectiveness expense was recorded in the third quarter and first nine months of 2018 or 2017.
Changes in the fair value of outstanding cash flow hedges recorded in OCI for the first nine months of 2018 and 2017 totaled an increase of $0.6 million and a decrease of $1.2 million, respectively. The Company expects to relieve substantially the entire balance in OCI as of September 28, 2018 to the Consolidated Statements of Income within the next 18-month period. Refer to Note J for additional OCI details.

Legal Proceedings. For information regarding legal proceedings relating to Chronic Beryllium Disease Claims, refer to Note R ("Contingencies and Commitments") in the Company's 2017 Annual Report on Form 10-K.
Other Litigation. The Company is party to several pending legal proceedings and claims arising in the normal course of business. The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the event the Company determines that a loss is not probable, but is reasonably possible, and it becomes possible to develop what the Company believes to be a reasonable range of possible loss, then the Company will include disclosure related to such matters. To the extent there is a reasonable possibility that the losses could exceed any amounts accrued, the Company will adjust the accrual in the period the determination is made, disclose an estimate of the additional loss or range of loss, indicate that the estimate is immaterial with respect to its financial statements as a whole or, if the amount of such adjustment cannot be reasonably estimated, disclose that an estimate cannot be made.
Environmental Proceedings. The Company has an active environmental compliance program and records reserves for the probable cost of identified environmental remediation projects. The reserves are established based upon analyses conducted by the Company’s engineers and outside consultants and are adjusted from time to time based upon ongoing studies, the difference between actual and estimated costs, and other factors. The reserves may also be affected by rulings and negotiations with regulatory agencies. The undiscounted reserve balance was $6.5 million at both September 28, 2018 and December 31, 2017. Environmental projects tend to be long-term, and the final actual remediation costs may differ from the amounts currently recorded.

New Accounting Pronouncements
New Pronouncements Adopted: In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires an employer to report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by pertinent employees during the period. This ASU requires non-service cost components of net benefit cost to be presented in a caption below the Company's Operating profit and allows only the service cost component to be eligible for capitalization. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those periods, with early adoption permitted. The Company adopted the new standard as of January 1, 2018 and applied its amendments retrospectively for the presentation of service cost and other components of net benefit cost on the income statement and prospectively for the capitalization of service cost and net periodic postretirement benefits in assets. The application of ASU 2017-07 resulted in an increase to Operating profit of $0.4 million and $1.0 million for the third quarter and first nine months of 2017, respectively, which was offset by a corresponding increase in Other non-operating expense, net. The adoption of this ASU did not have a material effect on the Company's financial condition or liquidity. The Company utilized this ASU's practical expedient, which permits the Company to use the amounts disclosed in its Pensions and Other Post-employment Benefits note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), which supersedes previous revenue recognition guidance. The Company adopted the new standard using the modified retrospective method as of January 1, 2018. Prior periods were not retrospectively adjusted. This approach was applied to all contracts not completed as of January 1, 2018. The new standard primarily impacted the Company's timing of revenue recognition for certain contracts and subcontracts with the United States (U.S.) government that contain termination for convenience clauses, and due to the cumulative impact of adopting ASC 606, the Company recorded a reduction to beginning retained earnings of $0.4 million, net of tax as summarized below:

The adoption of the standard did not have a material impact to the Company's consolidated financial statements. Refer to Note B for additional disclosures relating to ASC 606.
New Pronouncements Issued: In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which amends and simplifies existing guidance to allow companies to more accurately present the economic effects of risk management activities in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases, which eliminates the off-balance-sheet accounting for leases. The new guidance will require lessees to report their operating leases as both an asset and liability on the balance sheet and disclose key information about leasing arrangements. This ASU is required to be applied using a modified retrospective adoption method with the option of applying the guidance either retrospectively to each prior comparative reporting period presented or retrospectively at the beginning of the period of adoption. Early adoption is permitted. The Company will adopt this ASU on January 1, 2019 and will apply it retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment to retained earnings. The Company will elect to apply the practical expedients that do not require reassessment of existing contracts for embedded leases or to reassess lease classification or initial direct costs. In preparation for the adoption, the Company, along with an outside consultant, has executed on its project plan to identify a complete lease population, analyze lease agreements, and evaluate technology solutions. The Company selected and began implementing a new lease management system during the third quarter of 2018. Once the transition to the new system is completed, this software will enable us to quantify the full impact this ASU will have on our consolidated financial statements.
No other recently issued or effective ASUs had, or are expected to have, a material effect on the Company's results of operations, financial condition, or liquidity.

Revenue Recognition Accounting Policy (Policies)

Accounting Policies [Abstract]  
Revenue Recognition, Policy [Policy Text Block]
Net sales consist primarily of revenue from the sale of precious and non-precious specialty metals, beryllium and copper-based alloys, beryllium composites, and other products into numerous end markets. The Company requires an agreement with a customer that creates enforceable rights and performance obligations. The Company generally recognizes revenue, in an amount that reflects the consideration to which it expects to be entitled, upon satisfaction of a performance obligation by transferring control over a product to the customer. Control over the product is generally transferred to the customer when the Company has a present right to payment, the customer has legal title, the customer has physical possession, the customer has the significant risks and rewards of ownership, and/or the customer has accepted the product.

Shipping and Handling Costs: The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill our promise to transfer the associated products. Accordingly, customer payments of shipping and handling costs are recorded as a component of net sales, and related costs are recorded as a component of cost of sales.

Taxes Collected from Customers and Remitted to Governmental Authorities: Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Product Warranty: Substantially all of the Company’s customer contracts contain a warranty that provides assurance that the purchased product will function as expected and in accordance with certain specifications. The warranty is intended to safeguard the customer against existing defects and does not provide any incremental service to the customer.

Transaction Price Allocated to Future Performance Obligations: ASC 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied at September 28, 2018. Remaining performance obligations include noncancelable purchase orders and customer contracts. The guidance provides certain practical expedients that limit this requirement. As such, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. After considering the practical expedient, at September 28, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $33.0 million, of which $4.0 million will be recognized in 2018.

Contract Costs: The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs primarily relate to sales commissions, which are included in selling, general, and administrative expenses.
