Accounting Policies [Abstract]  
Significant Accounting Policies Significant Accounting Policies
Organization:  Materion Corporation (the Company) is a holding company with subsidiaries that have operations in the United States, Europe, and Asia. These operations manufacture advanced engineered materials used in a variety of end markets, including semiconductor, industrial, aerospace and defense, automotive, energy, consumer electronics, and telecom and data center. The Company has four reportable segments: Performance Alloys and Composites, Advanced Materials, Precision Optics, and Other. Other includes unallocated corporate costs.
Refer to Note C for additional segment details. The Company distributes its products through a combination of company-owned facilities and independent distributors and agents.
Business Combinations: The Company records assets acquired and liabilities assumed at the date of acquisition at their respective fair values. Intangible assets acquired in a business combination are recognized and reported apart from goodwill. Goodwill represents the excess purchase price over the fair value of the tangible net assets and intangible assets acquired in a business combination. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
The amounts reflected in Note B are the results of the preliminary purchase price allocation for the HCS-Electronic Materials acquisition and will be updated upon completion of the final valuation. The Company is required to complete the purchase price allocation within 12 months of the acquisition date. If such completion of the allocation results in a change in the preliminary values, the measurement period adjustment will be recognized in the period in which the adjustment amount is determined.
Use of Estimates:  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.
Consolidation:  The Consolidated Financial Statements include the accounts of Materion Corporation and its subsidiaries. All of the Company’s subsidiaries were wholly owned as of December 31, 2021. Intercompany accounts and transactions are eliminated in consolidation.
Cash Equivalents:  All highly liquid investments with a maturity of three months or less when purchased are considered to be cash equivalents.
Accounts Receivable:  An allowance for doubtful accounts is maintained for the expected losses resulting from the inability of customers to pay amounts due. The Company considers the current market conditions and credit losses related to the Company's trade receivables based on the macroeconomic environment, geographic considerations, and other expected market trends. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns, and other analyses of historical data and trends. Accounts receivable were net of an allowance for credit losses of $0.5 million at both December 31, 2021 and 2020. The change in the allowance for credit losses includes expense and net write-offs, neither of which were material. The Company extends credit to customers based upon their financial condition, and collateral is not generally required.
Inventories: Inventories are stated at lower of cost or net realizable value. All of the Company's inventories, except for its bertrandite ore mine which values inventory using a weighted average cost method, including raw materials, manufacturing supplies inventory as well as international (outside the U.S.) inventories, have been valued using the first-in, first-out (FIFO) method as of December 31, 2021 and 2020.
Property, Plant, and Equipment:  Property, plant, and equipment is stated on the basis of cost. Depreciation is computed principally by the straight-line method, except certain assets for which depreciation may be computed by the units-of-production method. The depreciable lives that are used in computing the annual provision for depreciation by class of asset are primarily as follows:
 Years
Land improvements
10 to 20
Buildings
20 to 40
Leasehold improvementsLife of lease
Machinery and equipment
3 to 15
Furniture and fixtures
4 to 10
Automobiles and trucks
3 to 8
Research equipment
3 to 10
Computer hardware
3 to 10
Computer software
3 to 10
An asset acquired under a finance lease will be recorded at the lesser of the present value of the projected lease payments or the fair value of the asset and will be depreciated in accordance with the above schedule. Leasehold improvements will be depreciated over the life of the improvement if it is shorter than the life of the lease. Repair and maintenance costs are expensed as incurred.
Mineral Resources and Mine Development: Property acquisition costs are capitalized as mineral resources on the balance sheet and are depleted using the units-of-production method based upon total estimated recoverable proven reserves of the beryllium-bearing bertrandite ore body. The Company uses beryllium pounds as the unit of accounting measure, and depletion expense is recorded on a pro-rata basis based upon the amount of beryllium pounds extracted as a percentage of total estimated beryllium pounds contained in the ore body.
Mine development costs at our open pit surface mines include drilling, infrastructure, other related costs to delineate an ore body and the removal of overburden to initially expose an ore body. Costs incurred before mineralization is classified as proven and probable reserves are expensed and classified as exploration expense. Capitalization of mine development project costs, that meet the definition of an asset, begins once mineralization is classified as proven and probable reserves.
In 2020, the Company expanded a mine to further develop an ore body. Since the pre-production phase ended when ore was first extracted from this mine, the Company recognized approximately $12.9 million of mine development costs in 2020 as a component of cost of sales. This expansion is expected to benefit future periods.
The cost of removing overburden and waste materials to access the ore body at an open-pit mine prior to the production phase is capitalized during the development of an open-pit mine and are capitalized at each pit. These costs are amortized as the ore is extracted using the units-of-production method based upon total estimated recoverable proven reserves for the individual pit. The Company uses beryllium pounds as the unit of accounting measure for recording amortization.
To the extent that the aforementioned costs benefit an entire ore body, the costs are amortized over the estimated useful life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block area.
Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of costs applicable to sales. All other drilling and related costs are expensed as incurred.
Goodwill and Other Intangible Assets:  Goodwill is reviewed annually for impairment or more frequently if impairment indicators arise. The Company conducts its annual goodwill and indefinite-lived intangible asset impairment assessment as of the first day of the fourth quarter, or more frequently under certain circumstances. For the purpose of the goodwill impairment assessment, the Company has the option to perform a qualitative assessment (commonly referred to as "step zero") to determine whether further quantitative analysis of impairment of goodwill or indefinite-lived intangible assets is necessary or a quantitative assessment ("step one") where the Company estimates the fair value of each reporting unit using a discounted cash flow method (income approach). Goodwill is assigned to the reporting unit, which is the operating segment level or one level below the operating segment. Intangible assets with finite lives are amortized using the straight-line method or effective interest method, as applicable, over the periods estimated to be benefited, which is generally 20 years or less. Finite-lived intangible assets are also reviewed for impairment if facts and circumstances warrant.
Long-Lived Asset Impairment: Management performs impairment tests of long-lived assets, including property and equipment, whenever an event occurs or circumstances change that indicate that the carrying value may not be recoverable or the useful life of the asset has changed. Upon indications of impairment, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The asset group would be considered impaired when the estimated future undiscounted cash flows generated by the asset group are less than its carrying value.  If such undiscounted cash flows indicate that the carrying value of the asset group is not recoverable, impairment losses are measured by comparing the estimated fair value of the asset group to its carrying amount.
Derivatives:  The Company recognizes all derivatives 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, a component of shareholders’ equity, until the hedged item is recognized in earnings. If the derivative is designated as a fair value hedge, changes in fair value are offset against the change in the fair value of the hedged asset, liability, or commitment through earnings. The ineffective portion of a derivative’s change in fair value, if any, is recognized in earnings immediately. If a derivative is not a hedge, changes in its fair value are adjusted through the income statement.
Asset Retirement Obligation:  The Company records a liability to recognize the legal obligation to remove an asset at the time the asset is acquired or when the legal liability arises. The liability is recorded for the present value of the ultimate obligation by discounting the estimated future cash flows using a credit-adjusted risk-free interest rate. The liability is accreted over time, with the accretion charged to expense. An asset equal to the fair value of the liability is recorded concurrent with the liability and depreciated over the life of the underlying asset.
Unearned Income:  Expenditures for capital equipment to be reimbursed under government contracts are recorded in property, plant, and equipment, while the reimbursements for those expenditures are recorded in unearned income, a liability on the balance sheet. When the assets subject to reimbursement are placed in service, the total cost is depreciated over the useful lives, and the unearned income liability is reduced and credited to cost of sales on the Consolidated Statements of Income ratably with the annual depreciation expense.
Also included in Unearned Income as of December 31, 2021 and 2020, are $72.6 million and $58.8 million, respectively, of customer prepayments. See Note L for additional discussion.
Advertising Costs: The Company expenses all advertising costs as incurred. Advertising costs were $0.3 million in 2021, $0.3 million in 2020, and $0.7 million in 2019.
Stock-based Compensation:  The Company recognizes stock-based compensation expense based on the grant date fair value of the award over the period during which an employee is required to provide service in exchange for the award. Stock-based awards include performance-based restricted stock units (PRSUs), restricted stock units (RSUs), and stock appreciation rights (SARs). The fair value of PRSUs and RSUs is primarily based on the closing market price of a share of the Company's common stock on the date of grant, modified as appropriate to take into account the features of such grants. SARs are granted with an exercise price equal to the closing price of the Company's common shares on the date of grant. The fair value of SARs is determined using a Black-Scholes option-pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate, and the expected dividend yield. The portion of the PRSU awards that are valued based on the Company's total shareholder return as compared to peers is valued using Monte Carlo simulations, which incorporates assumptions regarding the expected volatility, the expected correlation, and the risk-free interest rate. See Note R for additional information about stock-based compensation.
Capitalized Interest: Interest expense associated with active capital asset construction and mine development projects is capitalized and amortized over the future useful lives of the related assets.
Income Taxes:  The Company uses the liability method in measuring the provision for income taxes and recognizing deferred tax assets and liabilities on the balance sheet. The Company will record a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized, as warranted by current facts and circumstances. The Company applies a more-likely-than-not recognition threshold for all tax uncertainties and will record a liability for those tax benefits that have a less than 50% likelihood of being sustained upon examination by the taxing authorities.
Net Income Per Share:  Basic earnings per share (EPS) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the assumed conversion of all dilutive common stock equivalents as appropriate using the treasury stock method.
New Pronouncements Adopted:  In November 2020, the Securities Exchange Commission (SEC) issued the SEC Final Rule Release No. 33-10890, Management’s Discussion and Analysis, Selected Financial Data, and Supplementary Financial Information, which simplifies Management’s Discussion and Analysis (MD&A) and certain financial disclosure requirements in SEC regulation S-K. The final rule eliminates Regulation S-K, Item 301, “Selected Financial Data”, simplifies Regulation S-
K, Item 302, “Supplementary Financial Information”, and amends certain aspects of Regulation S-K, Item 303, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. The Company adopted the standard on December 31, 2021. The adoption did not materially impact the Company's financial statements or disclosures.
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires companies to apply ASC 606 on the acquisition date to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. This is an exception to the recognition and measurement principle in ASC 805 which generally requires an acquirer to recognize and measure the assets it acquires and the liabilities it assumes at fair value on the acquisition date. For public entities, the guidance is effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. The Company has early adopted this guidance and has applied it to the accounting for contract assets and contract liabilities acquired as part of the HCS-Electronic Materials (as defined in Note B) acquisition.
New Accounting Guidance Issued and Not Yet Adopted: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. The Company does not expect the transition away from LIBOR to have a material impact on interest expense or on the 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.

Business Combination Acquisition
On November 1, 2021, the Company acquired the industry-leading electronic materials business of H.C. Starck Group GmbH (HCS-Electronic Materials) for a cash purchase price of approximately $395.9 million, on a cash-free, debt-free basis, subject to a customary purchase price adjustment mechanism. Acquisition-related transaction and integration costs totaled $11.8 million in 2021. These costs are included in selling, general, and administrative expenses in the Consolidated Statements of Income. Acquisition-related inventory step-up expense during the fourth quarter of 2021 was $5.0M and are recorded in cost of sales in the Consolidated Statements of Income. The Company financed the purchase price for the HCS-Electronic Materials acquisition with a new $300 million five-year term loan pursuant to a delayed draw term loan facility entered during October 2021 and $103 million of borrowings under its amended revolving credit facility, which was also extended to expire five years in October 2026. The interest rate for the term loan is based on LIBOR plus a tiered rate determined by the Company's quarterly leverage ratio. This acquired business operates within the Performance Alloys and Composites and Advanced Materials segments, and the results of operations are included as of the date of acquisition. The combination of Materion and HCS-Electronic Materials enhances the Company's position as the leading supplier to the high growth semiconductor industry.

The preliminary purchase price allocation for the acquisition is as follows:
(Thousands)November 1, 2021

Cash and cash equivalents$3,685 
Accounts receivable28,352 
Inventories70,681

Other long-term liabilities5,543 
Operating lease liabilities6,042 
Deferred income taxes20,300 
Total liabilities assumed$48,751 
Net assets acquired$395,937 

Assets acquired and liabilities assumed are recognized at their respective fair values as of the acquisition date. The Company engaged specialists to assist in the valuation of inventories, property, plant, and equipment, and intangible assets. The estimates in the purchase price allocation are based on available information and will be revised during the measurement period, not to exceed 12 months, as additional information becomes available on tax-related items, and as additional analyses are performed. The purchase price allocation is preliminary as a result of the proximity of the acquisition date to December 31, 2021, and as a result, no elements of the purchase price allocation have been finalized. During the measurement period for each acquisition, we will adjust assets and liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities as of that date. The effect of measurement period adjustments to the estimated fair values will be reflected as if the adjustments had been completed on the acquisition date.

In determining the fair value of the amounts above, inventory is fair valued based on the comparative sales method for work in process and finished goods at the selling price less cost to dispose and remaining manufacturing effort. The remaining working capital accounts' carrying values approximate fair value. For property, plant and equipment and intangible asset values, the Company utilized various forms of the income, cost and market approaches depending on the asset being valued. The Company used a relief from royalty method under the income approach to value its trade names and developed technology and the multi-period excess earnings method under the income approach to value customer relationships. The significant assumptions used to estimate the fair value of these intangible assets included the discount rate and certain assumptions that form the basis of future cash flows (including revenue growth rates, royalty rates for trade names and developed technology, and attrition rates for customer relationships). Inputs were generally determined by taking into account independent appraisals and historical data, supplemented by current and anticipated market conditions and are considered Level 3 assets as the assumptions are unobservable inputs developed by the Company.

The Company's consolidated financial statements include the results of operations of HCS-Electronic Materials from the acquisition date through December 31, 2021.

As part of the acquisition, the Company recorded approximately $178.2 million of goodwill allocated between its Advance Materials and Performance Alloys and Composites segments based on the relative fair values. Goodwill was calculated as the excess of the purchase price over the estimated fair values of the tangible net assets and intangible assets acquired and primarily attributable to the synergies expected to arise after the acquisition dates. The goodwill is not expected to be deductible for U.S. tax purposes.
The following table reports the intangible assets by asset category as of the closing date:
(Thousands)Value at AcquisitionUseful Life
Customer relationships$50,200 13 years
Technology35,300 13 years
Trade name22,300 15 years
Total$107,800 

The amounts of revenue and income (loss) before taxes of HCS-Electronic Materials since the acquisition date in the consolidated statements are $26.7 million and ($2.8) million, respectively and include two months of the purchase accounting inventory step-up expense. Had the HCS-Electronic Materials acquisition occurred as of the beginning of fiscal 2020, the Company's sales and income (loss) before taxes would have been as follows:
(Unaudited)
Year Ended December 31,
20212020
Net Sales$1,659,620 $1,308,300 
Profit income (loss) before taxes$91,551 $(17,761)

The unaudited pro forma financial information has been calculated after applying our accounting policies and adjusting the historical results with pro forma adjustments that assume the acquisition occurred on January 1, 2020. These unaudited pro forma results do not represent financial results realized, nor are they intended to be a projection of future results. The transaction accounting adjustments and other adjustments are based on available information and assumptions that the Company’s management believes are reasonable. Such adjustments are estimates and actual experience may differ from expectations. The amortization of inventory step-up from the preliminary purchase price allocation of approximately $15 million of expense is reflected in the 2020 unaudited pro forma income (loss) before taxes above. Additionally, the 2020 pro forma income (loss) before taxes includes approximately $10 million of additional interest expense related to committed financing to fund the acquisition, annual acquisition-related intangible asset amortization expense of $8.2 million, and transaction expenses of $5.5 million as if it occurred on January 1, 2020.

On July 17, 2020, the Company completed the acquisition of Optics Balzers AG (Optics Balzers), an industry leader in thin film optical coatings. The purchase price for Optics Balzers was $136.1 million, including the assumption of $22.5 million of debt. The transaction was funded with cash on hand. Based on the fair value of assets acquired and liabilities assumed, goodwill of $70.6 million and identifiable intangible assets of $49.3 million were recorded. Goodwill associated with this acquisition is not tax deductible. This acquisition is being reported in the Company's Precision Optics segment and the results of Optics Balzers are not material to the Company's Consolidated Financial Statements. No material measurement period adjustments have been recorded during 2021, and as of October 1, 2021, the purchase price allocation is complete.

Revenue Recognition
12 Months Ended
Dec. 31, 2021
Revenue from Contract with Customer [Abstract]  
Revenue from Contract with Customer Revenue RecognitionNet 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 its promise to transfer the associated products. Accordingly, customer payments for 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 December 31, 2021. Remaining performance obligations include non-cancelable 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 December 31, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $81.9 million.
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:

Unbilled receivables
7,961 8,832 (871)(10)%
Unearned revenue
7,770 7,713 57 %
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 2021.
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. The Company recognized approximately $6.8 million of the December 31, 2020 unearned amounts as revenue during 2021. The Company recognized approximately $3.2 million of the December 31, 2019 unearned amounts as revenue during 2020.

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.

Restructuring and Related Activities [Abstract]  
Restructuring Restructuring
During 2020, the Company committed to a plan to sell its Large Area Coatings (LAC) business (a reporting unit within the Precision Optics segment) and determined that it met the criteria to be classified as held for sale. The Company recorded a goodwill impairment charge of $9.1 million in the first quarter of 2020 to write-off the remaining balance of goodwill for the LAC reporting unit. In addition, the Company estimated the fair value of the disposal group as a whole, less costs to sell, and compared the fair value to the remaining carrying value. Based on this review, the Company recorded an additional $1.4 million asset impairment loss. During the third quarter of 2020, the Company concluded that it intended to close its LAC business and, as a result, only a portion of the fixed assets of the LAC business are classified as held for sale. At December 31, 2020, fixed assets totaling $0.2 million were classified as held for sale and reflected within Prepaid and other current assets in the Consolidated Balance Sheet, and these assets were disposed of in early 2021.
In 2021, the Company resolved the remaining restructuring items that held over from 2020 and as a result reversed $0.4 million of accruals that were on the balance sheet at the end of 2020.
Costs associated with the closure of the LAC business totaled $1.7 million in 2020 and included $0.7 million of severance associated with approximately 20 employees and $1.0 million of facility and other related costs.
Remaining severance payments of $0.6 million and facility costs of $1.0 million related to these initiatives are reflected within Salaries and wages and Other liabilities and accrued items, respectively, in the Consolidated Balance Sheet. All remaining severance payments were paid in 2021.
In addition, in 2020, the Company completed additional cost reduction actions in order to align costs with commensurate business levels in its Precision Optics segment. These actions were accomplished through elimination of vacant positions, consolidation of roles, and staff reductions. Costs associated with these actions totaled $0.4 million and included severance associated with approximately 28 employees and other related costs, all of which was paid during 2020.
Also, in 2020, the Company initiated a restructuring plan in its Performance Alloys and Composites segment to close its Warren, Michigan and Fremont, California locations. Costs associated with the plan totaled $8.8 million in 2020 and included $2.1 million of severance associated with approximately 63 employees, and $5.3 million of facility and other related costs. Remaining severance payments of $0.5 million and facility costs of $0.5 million related to these initiatives are reflected within Salaries and wages and Other liabilities and accrued items in the Consolidated Balance Sheet as of December 31, 2020. The Company does not expect to incur any additional costs associated with these initiatives. Remaining severance payments as of December 31, 2021 were immaterial.
In 2019, the Company initiated a restructuring plan in its LAC business to reduce headcount, idle certain machinery and equipment, and exit a facility in Windsor, Connecticut. Costs associated with this plan also included severance and related costs for 19 employees, all of which was paid out by the end of 2020.
In addition, in 2019, the Company completed cost reduction actions in order to align costs with commensurate business levels. These actions were accomplished through elimination of vacant positions, consolidation of roles, and staff reduction. Costs associated with these actions were in the Other segment and included severance associated with seven employees and other related costs. All severance payments were paid by the end of 2020.
Costs associated with cost reduction actions in 2018 were in the Advanced Materials segment and included severance associated with approximately forty employees and other related costs. Remaining severance payments as of December 31, 2021 are immaterial.

The increase in interest expense in 2020 compared to 2019 was driven by increased borrowings under our revolving credit facility during 2020 primarily to finance the acquisition of Optics Balzers. Amortization of deferred financing costs within interest expense was $1.0 million in 2021, $0.8 million in 2020, and $1.0 million in 2019.

On March 11, 2021, President Biden signed the American Rescue Plan (the Rescue Plan) into law. The Rescue Plan, among other things, extended and enhanced a number of current-law tax incentives for businesses. The Company has examined the impact of the Rescue Plan on its business and has determined it does not have a material impact to its consolidated financial statements.

The Company had deferred income tax assets offset with a valuation allowance for certain foreign and state net operating losses, a domestic capital loss carryforward, state investment and research and development tax credit carryforwards, and deferred tax assets that are not likely to be realized for certain of the Company's controlled foreign corporations. The Company intends to maintain a valuation allowance on these deferred tax assets until a realization event occurs to support reversal of all or a portion of the allowance.

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. As of December 31, 2021, the Company came out of a three year cumulative loss in Germany in the fourth quarter due to improving profitability. Management determined that there is sufficient positive evidence to conclude that it is more likely than not that additional deferred taxes are realizable and released the related $6.9 million valuation allowance on deferred tax assets in Germany, resulting in an income tax benefit for this amount.

At December 31, 2021, for income tax purposes, the Company had foreign net operating loss carryforwards of $20.8 million that do not expire, and $6.7 million that expire in calendar years 2022 through 2027. The Company had state net operating loss carryforwards of $24.5 million that expire in calendar years 2022 through 2040 and state tax credits of $4.2 million that expire in calendar years 2022 through 2036. The Company also had a capital loss carryforward of $8.4 million that expires in 2026. A valuation allowance of $5.0 million has been provided against certain foreign and state net operating loss carryforwards, a U.S. capital loss carryforward, and state tax credits due to uncertainty of their realization.

The Company files income tax returns in the U.S. federal jurisdiction, and in various state, local, and foreign jurisdictions. With limited exceptions, the Company is no longer subject to U.S. federal examinations for years before 2018, state and local examinations for years before 2017, and foreign examinations for tax years before 2015.

We operate under a tax holiday in Malaysia, which is effective through July 31, 2022 and may be extended if certain additional requirements are satisfied. The tax holiday is conditional upon our meeting certain employment, sales, and investment thresholds. The impact of this tax holiday decreased foreign taxes by $0.4 million and $0.5 million in 2021 and 2020, respectively. The benefit of the tax holiday on net income per share (diluted) was $0.02 and $0.03 in 2021 and 2020, respectively.

A reconciliation of the Company’s unrecognized tax benefits for the year-to-date periods ended December 31, 2021 and 2020 is as follows:

Included in the balance of unrecognized tax benefits, including interest and penalties, as of December 31, 2021 and December 31, 2020 are $1.2 million and $2.7 million, respectively, of tax benefits that would affect the Company’s effective tax rate if recognized. It is reasonably possible that the amount of unrecognized tax benefits will change in the next twelve months; however, we do not expect the change to have a material impact on the Consolidated Statements of Income or the Consolidated Balance Sheets.

The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying Consolidated Statements of Income. Accrued interest and penalties are included on the related tax liability line in the Consolidated Balance Sheets. The amount of interest and penalties, net of the related tax benefit, recognized in earnings was immaterial during 2021, 2020, and 2019. As of December 31, 2021 and 2020, accrued interest and penalties, net of the related tax benefit, were immaterial.
Income taxes paid during 2021, 2020, and 2019, were approximately $21.8 million, $3.9 million, and $9.3 million, respectively.
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 as of December 31, 2021. The amount of such unrepatriated earnings totaled $102.3 million as of
December 31, 2021. It is not practicable to estimate the additional income taxes and applicable withholding taxes that would be payable on the remittance of such undistributed earnings.

The Company takes and records the results of a physical inventory count of its precious metals on a quarterly basis. The Company's precious metal operations include a refinery that processes precious metal-containing scrap and other materials from its customers, as well as its own internally generated scrap. The Company also outsources portions of its refining requirements to other vendors, particularly those materials with longer processing times. The precious metal content within these various refine streams may be in solutions, sludges, and other non-homogeneous forms and can vary over time based upon the input materials, yield rates, and other process parameters. The determination of the weight of the precious metal content within the refine streams as part of a physical inventory count requires the use of estimates and calculations based upon assays, assumed recovery percentages developed from actual historical data and other analyses, the total estimated volumes of solutions and other materials within the refinery, data from the Company's refine vendors, and other factors. The resulting calculated weight of the precious metals in the Company's refine operations may differ, in either direction, from what its records indicate that the Company should have on hand, which would then result in an adjustment to its pre-tax income in the period when the physical inventory was taken, and the related estimates were made.
The Company maintains the majority of the precious metals and copper used in production on a consignment basis in order to reduce our exposure to metal price movements and to reduce our working capital investment. The notional value of off-balance sheet precious metals and copper was $480.2 million as of December 31, 2021 versus $400.0 million as of December 31, 2020.
Amounts for the year ended December 31, 2020 have been revised to reflect a $44.6 million reclassification out of work in process and into finished goods inventory.

The Company received $63.5 million from the U.S. Department of Defense (DoD), in previous periods, for reimbursement of the DoD's share of the cost of equipment. This amount was recorded in property, plant, and equipment and the reimbursements are reflected in Unearned income on the Consolidated Balance Sheets. The equipment was placed in service during 2012, and its full cost is being depreciated in accordance with Company policy. The unearned income liability is being reduced ratably with the depreciation expense recorded over the life of the equipment. Unearned income was reduced by $4.3 million in both 2021 and 2020 and $4.4 million in 2019 and credited to cost of sales in the Consolidated Statements of Income, offsetting the impact of the depreciation expense on the associated equipment on the Company's cost of sales and gross margin.
We recorded depreciation and depletion expense of $31.4 million in 2021, $30.9 million in 2020, and $30.3 million in 2019. Depreciation, depletion, and amortization as shown on the Consolidated Statement of Cash Flows is net of the reduction in the unearned income liability in 2021, 2020, and 2019. The net carrying value of capitalized software was $5.4 million and $5.0 million at December 31, 2021 and December 31, 2020, respectively. Depreciation expense related to software was $1.8 million, $1.8 million, and $2.4 million in 2021, 2020, and 2019, respectively.

Customer Prepayments Customer PrepaymentsThe Company entered into investment and master supply agreements with a customer to procure equipment to manufacture product for the customer. The customer provided prepayments to the Company to enable the Company to purchase and install certain equipment and make necessary infrastructure improvements to supply product to the customer. The Company will own the equipment and be responsible for operating and maintenance costs. The prepayment from the customer will be applied when the product is sold and delivered to the customer in connection with a master supply agreement. Accordingly, as of December 31, 2021 and 2020, $72.6 million and $58.8 million, respectively, of prepayments are classified as Unearned income in the Consolidated Balance Sheet and the liabilities are expected to be settled as commercial shipments are made.

Leases [Abstract]  
Leasing Arrangements Leasing Arrangements
The Company leases warehouse and manufacturing real estate, and manufacturing and computer equipment under operating leases with lease terms ranging up to 25 years. Several operating lease agreements contain options to extend the lease term and/or options for early termination. The lease term consists of the non-cancelable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option. As of December 31, 2021, we had no material leases that had yet to commence.
The discount rate implicit within the leases is generally not determinable, and, therefore, the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for leases is determined based on the lease term over which lease payments are made, adjusted for the impact of collateral.

In 2020, the Company recorded a $9.1 million goodwill impairment charge to write-off the remaining balance of goodwill for the LAC reporting unit which was closed as of December 31, 2020. The results of the Company's 2021, 2020, and 2019 annual goodwill impairment assessments indicated that no other goodwill impairment existed.
There were no accumulated impairment losses in 2021, compared to $20.6 million at December 31, 2020, all of which related to the LAC reporting unit.

In 2021, the Company amended and restated our $375.0 million revolving credit facility (Credit Agreement) in connection with the HCS-Electronic Materials acquisition. A $300 million delayed draw term loan facility was added to the Credit Agreement and the maturity date of the Credit Agreement was extended from 2024 to 2026. Moreover, the Credit Agreement also provides for an uncommitted incremental facility whereby, under certain conditions, the Company may be able to borrow additional term loans in an aggregate amount not to exceed $150.0 million. On November 1, 2021, Materion borrowed the full $300 million available under the delayed draw term loan facility and used the proceeds to pay a portion of the purchase price of the HCS-Electronic Materials acquisition.

The Credit Agreement provides the Company and its subsidiaries with additional capacity to enter into facilities for the consignment, borrowing, or leasing of precious metals and copper, and provides enhanced flexibility to finance acquisitions and other strategic initiatives. Borrowings under the Credit Agreement are secured by substantially all of the assets of the Company and its direct subsidiaries, with the exception of non-mining real property, precious metals, copper and certain other assets.
The Credit Agreement allows the Company to borrow money at a premium over LIBOR or prime rate and at varying maturities. The premium resets quarterly according to the terms and conditions available under the agreement. The Credit Agreement includes restrictive covenants relating to restrictions on additional indebtedness, acquisitions, dividends, and stock repurchases. In addition, the Credit Agreement includes covenants subject to a maximum leverage ratio and a minimum interest coverage ratio. We were in compliance with all of our debt covenants as of December 31, 2021 and December 31, 2020. Cash on hand up to $25 million can benefit the covenants and may benefit the borrowing capacity under the Credit Agreement. At December 31, 2021 and 2020, there was $452.3 million and $34.0 million outstanding under the Credit Agreement, respectively.

At December 31, 2021 and 2020 there was $46.3 million and $48.1 million letters of credit outstanding against the credit sub-facility, respectively. The Company pays a variable commitment fee that may reset quarterly (0.35% as of December 31, 2021) on the available and unborrowed amounts under the revolving credit line.
The available borrowings under the individual existing credit lines totaled $176.4 million as of December 31, 2021.

The benefit obligation decreased in 2021 due to actuarial gains that were driven by increases in the discount rate as well as participant census data updates.
In 2019, the Company's Board of Directors approved changes to the U.S. defined benefit pension plan. The Company froze the pay and service amounts used to calculate the pension benefits for active participants as of January 1, 2020. The Company recognized a non-cash pretax pension curtailment charge of $3.3 million associated with the plan amendment in 2019.

In determining the projected benefit obligation and the net benefit cost, as of a December 31 measurement date, the Company used the following weighted-average assumptions:

Rate of compensation increase2.87 %2.87 %2.99 %3.00 %3.00 %4.00 %
Discount Rate. The discount rate used to determine the present value of the projected and accumulated benefit obligation at the end of each year is established based upon the available market rates for high quality, fixed income investments whose maturities match the plan’s projected cash flows.
The Company uses a spot-rate approach to estimate the service and interest cost components of net periodic benefit cost for its defined benefit pension plans. The spot-rate approach applies separate discount rates for each projected benefit payment in the calculation.
Expected Long-Term Return on Plan Assets. Management establishes the domestic expected long-term rate of return assumption by reviewing historical trends and analyzing the current and projected market conditions in relation to the plan’s asset allocation and risk management objectives. Consideration is given to both recent plan asset performance as well as plan asset performance over various long-term periods of time, with an emphasis on the assumption being a prospective, long-term rate of return. Management consults with and considers the opinions of its outside investment advisers and actuaries when establishing the rate and reviews assumptions with the Audit Committee of the Board of Directors.
Rate of Compensation Increase. The rate of compensation increase assumption is no longer applicable for the domestic defined benefit due to the Company freezing the plan effective January 1, 2020. The rate of compensation assumption for the domestic retiree medical plan was 3.0% in both 2021 and 2020.
Assumptions for the defined benefit pension plans in Germany, Liechtenstein, and England are determined separately from the U.S. plan assumptions, based on historical trends and current and projected market conditions in each respective country. One plan in Germany is unfunded.

Governmental and corporate bonds are valued using both market observable inputs for similar assets that are traded on an active market and the closing price on the active market on which the individual securities are traded.
(c)Includes a mutual fund that typically invests at least 80% of its assets in equity and debt securities of companies in the real estate industry or related industries or in companies which own significant real estate assets at the time of investment.
(d)Certain assets that are measured at fair value using the NAV practical expedient have not been classified in the fair value hierarchy.
(e)Pooled investment fund consists of various investment types including equity investments covering a range of geographies and including investment managers that hold long and short positions, property investments, and other
multi-strategy funds which combine a range of different credit, equity, and macro-orientated ideas and dynamically allocate funds across asset classes.
(f)Includes a fund that invests in a broad portfolio of hedge funds.
The Company’s domestic defined benefit pension plan investment strategy, as approved by the Governance and Organization Committee of the Board of Directors, is to employ an allocation of investments that will generate returns equal to or better than the projected long-term growth of pension liabilities so that the plan will be self-funding. The return objective is to maximize investment return to achieve and maintain a 100% funded status over time, taking into consideration required cash contributions. The allocation of investments is designed to maximize the advantages of diversification while mitigating the risk and overall portfolio volatility to achieve the return objective. Risk is defined as the annual variability in value and is measured in terms of the standard deviation of investment return. Under the Company’s investment policies, allowable investments include domestic equities, international equities, fixed income securities, cash equivalents, and alternative securities (which include real estate, private venture capital investments, hedge funds, and tactical asset allocation). Ranges, in terms of a percentage of the total assets, are established for each allowable class of security. Derivatives may be used to hedge an existing security or as a risk reduction strategy. Current asset allocation guidelines are to invest 10% to 40% in equity securities, 60% to 90% in fixed income securities and cash, and up to 20% in alternative securities. Management reviews the asset allocation on a quarterly or more frequent basis and makes revisions as deemed necessary.
None of the plan assets noted above are invested in the Company’s common stock.

Cash Flows

Stock-based Compensation

Share-based Payment Arrangement [Abstract]  
Stock-based Compensation Stock-based Compensation
The Company maintains two stock incentive plans (the 2006 Stock Incentive Plan and the 2006 Non-employee Director Equity Plan) that have been approved by its shareholders. These plans authorize the granting of option rights, stock appreciation rights (SARs), performance-restricted shares, performance shares, performance units, restricted shares, and restricted stock units (RSUs).
Stock-based compensation expense, which includes awards settled in shares and in cash and is recognized as a component of selling, general, and administrative (SG&A) expenses, was $7.3 million, $5.7 million, and $11.1 million in 2021, 2020, and 2019, respectively. The Company derives a tax deduction measured by the excess of the market value over the grant price at the date stock-based awards vest or are exercised. The Company recognized $0.9 million, $0.5 million, and $2.1 million of tax benefits in 2021, 2020, and 2019, respectively, relating to the issuance of common stock for the exercise/vesting of equity awards.
The following sections provide information on awards settled in shares.
SARs. The Company grants SARs to certain employees. Upon exercise of vested SARs, the participant will receive a number of shares of common stock equal to the spread (the difference between the market price of the Company’s common shares at the time of exercise and the strike price established on the grant date) divided by the common share price. The strike price of the SARs is equal to the market value of the Company’s common shares on the day of the grant. The number of SARs available to be issued is established by plans approved by the shareholders. The vesting period and the life of the SARs are established at the time of grant. The exercise of the SARs is generally satisfied by the issuance of treasury shares. SARs vest in equal installments annually over three years. SARs expire in seven years.

As of December 31, 2021, $1.1 million of expense with respect to non-vested SARs has yet to be recognized as expense over a weighted-average period of approximately 20 months. The total fair value of shares vested during 2021, 2020, and 2019 was $0.8 million, $1.5 million, and $1.9 million, respectively.
The weighted-average grant date fair value for 2021, 2020, and 2019 was $20.66, $13.67, and $17.76, respectively. The fair value will be amortized to compensation cost on a straight-line basis over the vesting period of three years, or earlier if the employee is retirement eligible and continued vesting is approved by the Board of Directors as defined in the Plan. Stock-based compensation expense relating to SARs was $0.9 million in each of the last three years.
The fair value of the SARs was estimated on the grant date using the Black-Scholes pricing model with the following assumptions:

The risk-free rate of return was based on U.S. Treasury yields with a maturity equal to the expected life of the award. The dividend yield was based on the Company's historical dividend rate and stock price. The expected volatility of stock was derived by referring to changes in the Company's historical common stock prices over a time-frame similar to the expected life of the award. In addition to considering the vesting period and contractual term of the award for the expected life assumption, the Company analyzes actual historical exercise experience for previously granted awards.
Restricted Stock Units (RSUs) - Employees. The Company may grant RSUs to employees of the Company. These units constitute an agreement to deliver shares of common stock to the participant at the end of the vesting period, which is defined at the date of the grant, and are forfeited should the holder’s employment terminate during the restriction period. The fair market value of the RSUs is determined on the date of the grant and is amortized over the vesting period. The vesting period is typically three years unless the recipient is retirement eligible and continued vesting is approved by the Board of Directors.
The fair value of RSUs settled in stock is based on the closing stock price on the date of grant. The weighted-average grant date fair value for 2021, 2020, and 2019 was $68.62, $51.55, and $58.33, respectively. Cash-settled RSUs are accounted for as liability-based compensation awards and adjusted based on the closing price of Materion’s common stock over the vesting period of three years.
Stock-based compensation expense relating to stock-settled RSUs was $3.5 million in 2021, $2.7 million in 2020, and $2.2 million in 2019. The unamortized compensation cost on the outstanding RSUs was $4.6 million as of December 31, 2021 and is expected to be recognized over a weighted-average period of 23 months. The total fair value of shares that vested during 2021 was $2.0 million, compared to $1.2 million in both 2020 and 2019.

RSUs - Non-Employee Directors. In 2021, 2020, and 2019, 9,904, 15,976, and 11,048 RSUs, with a one year vesting period, were granted to certain non-employee members of the Board of Directors. The weighted-average grant date fair value of these RSUs was $75.77, $48.42, and $68.79 in 2021, 2020, and 2019, respectively. The Company recognized $0.8 million of expense related to these awards in 2021, compared to $0.7 million of expense in both 2020, and 2019. At December 31, 2021, $0.3 million of expense with respect to non-vested RSU awards granted to the Board of Directors has yet to be recognized and will be amortized into expense over a weighted-average period of approximately four months.
Long-term Incentive Plans. Under the long-term incentive compensation plans, executive officers and selected other employees receive restricted stock unit awards based upon the Company’s performance over the defined period, typically three years. Total units earned for grants made in 2021, 2020, and 2019, may vary between 0% and 200% of the units granted based on the attainment of performance targets during the related three-year period. All grants will be settled in Materion common shares and are equity classified. Vesting of performance-based awards is contingent upon the attainment of threshold performance objectives.

Compensation expense is based upon the performance projections for the plan period of three years, the percentage of requisite service rendered, and the fair market value of the Company’s common shares on the date of grant. The offset to the compensation expense for the portion of the award to be settled in shares is recorded within shareholders’ equity and was $2.2 million for 2021, $2.0 million for 2020, and $3.3 million for 2019.
Directors' Deferred Compensation. Non-employee directors may defer all or part of their compensation into the Company’s common stock. The fair value of the deferred shares is determined at the share acquisition date and is recorded within shareholders’ equity. At December 31, 2021, shareholders’ equity included 0.1 million shares related to this plan.

Fair Value Information and Derivative Financial Instruments Fair Value Information and Derivative Financial Instruments
The Company measures and records financial instruments at fair value. A hierarchy is used for those instruments measured at fair value that distinguishes between assumptions based upon 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 following table summarizes the financial instruments measured at fair value on the Consolidated Balance Sheets at December 31, 2021 and 2020:

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 Company's deferred compensation investments and liabilities are based on the fair value of the investments corresponding to the employees’ investment selections, primarily in mutual funds, based on quoted prices in active markets for identical assets. Deferred compensation investments are primarily presented in Other assets. Deferred compensation liabilities are primarily presented in Other long-term liabilities.
The carrying values of the other working capital items and debt in the Consolidated Balance Sheets approximate fair values at December 31, 2021 and 2020.
The Company uses derivative contracts to hedge portions of its foreign currency exposures and may also use 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 in 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, the 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.
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 that changes in prices could have on the Company's margins and operating profit. The consigned metal is owned by financial institutions who 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. The Company may also enter into hedges to mitigate the risk relating to the prices of the metals which we process or refine.
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.
Copper. The Company also uses copper in its production processes. When possible, fluctuations in the purchase price of copper are passed on to customers in the form of price adders or reductions. While over time the Company's price exposure to copper is generally in balance, there can be a lag between the change in the Company's cost and the pass-through to its customers, resulting in higher or lower margins in a given period. To mitigate this impact, the Company hedges a portion of this pricing risk.
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 exposures. 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. Foreign currency contracts are typically layered in at different times for a specified exposure period in order to minimize the impact of market rate movements.
The use of derivatives is governed by policies adopted by the Audit and Risk Committee of the Board of Directors. The Company will only enter into a derivative contract if there is an underlying identified exposure. Contracts are typically held to maturity. The Company does not engage in derivative trading activities and does not use derivatives for speculative purposes. The Company only uses hedge contracts that are denominated in the same currency or 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 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.

Commitments and Contingencies Disclosure [Abstract]  
Contingencies and Commitments Contingencies and Commitments
Beryllium Cases
The Company is a defendant from time to time in proceedings in various state and federal courts brought by plaintiffs alleging that they have contracted, or have been placed at risk of contracting, beryllium sensitization or Chronic Beryllium Disease (CBD) or related ailments as a result of exposure to beryllium. Plaintiffs in beryllium cases seek recovery under theories of negligence and various other legal theories and seek compensatory and punitive damages, in many cases of an unspecified sum. Spouses, if any, often claim loss of consortium.
Employee cases, in which plaintiffs have a high burden of proof, have historically involved relatively small losses to the Company. Third-party plaintiffs (typically employees of customers) face a lower burden of proof than do the Company’s employees, but these cases have generally been covered by varying levels of insurance. Management has vigorously contested the beryllium cases brought against the Company.
Non-employee beryllium cases are covered by insurance, subject to certain limitations. The insurance covers defense costs and indemnity payments (resulting from settlements or court verdicts) and is subject to various levels of deductibles. Defense and indemnity costs were less than or equal to the deductible in both 2021 and 2020.
As of December 31, 2021, the Company was a defendant in two beryllium litigation cases, both of which were outstanding as of December 31, 2020. The Company does not expect the resolution of these matters to have a material impact on its consolidated financial statements.
Although it is not possible to predict the outcome of any pending litigation, the Company provides for costs related to litigation matters when a loss is probable, and the amount is reasonably estimable. Litigation is subject to many uncertainties, and it is possible that some of the actions could be decided unfavorably in amounts exceeding the Company’s reserves. An unfavorable outcome or settlement of a beryllium case or adverse media coverage could encourage the commencement of additional similar litigation. The Company is unable to estimate its potential exposure to unasserted claims.

Based upon currently known facts and assuming collectability of insurance, the Company does not believe that resolution of the current or any potential future beryllium proceedings will have a material adverse effect on the financial condition or cash flow of the Company. However, the Company’s results of operations could be materially affected by unfavorable results in one or more cases.
Environmental Proceedings
The Company has an active program for environmental compliance that includes the identification of environmental projects and estimating the impact on the Company’s financial performance and available resources. Environmental expenditures that relate to current operations, such as wastewater treatment and control of airborne emissions, are either expensed or capitalized as appropriate. The Company records reserves for the probable costs for identified environmental remediation projects. The Company’s environmental engineers perform routine ongoing analyses of the remediation sites and will use outside consultants to assist in their analyses from time to time. Reserve accruals are based upon their analyses and are established based on the reasonably estimable loss or range of loss. The accruals are revised for the results of ongoing studies, changes in strategies, inflation, and for differences between actual and projected costs. The accruals may also be affected by rulings and negotiations with regulatory agencies. The timing of payments often lags the accrual, as environmental projects typically require a number of years to complete.
The environmental reserves recorded represent the Company's best estimate of what is reasonably possible and cover existing or currently foreseen projects based upon current facts and circumstances. For sites where the investigative work and work plan development are substantially complete, the Company does not believe that it is reasonably possible that the cost to resolve environmental matters will be materially different than what has been accrued. For sites that are in the preliminary stages of investigation, the ultimate loss contingencies cannot be reasonably determined at the present time. As facts and circumstances change, the ultimate cost may be revised, and the recording of additional costs may be material in the period in which the additional costs are accrued. The Company does not believe that the ultimate liability for environmental matters will have a material impact on its financial condition or liquidity due to the nature of known environmental matters and the extended period of time over which environmental remediation normally takes place.
The undiscounted reserve balance at the beginning of the year, the amounts expensed and paid, and the balance at December 31, 2021 and 2020 are as follows:

The majority of expenses in both 2021 and 2020 was for various remediation projects at the Elmore, Ohio plant site.
Asset Retirement Obligations
The Company has asset retirement obligations related to its mine in Utah, as well as for certain leased facilities where the Company is contractually obligated to restore the facility back to its original condition at the end of the lease. The following represents a roll forward of the Company's asset retirement obligation liabilities for the years ended December 31, 2021 and 2020:

These obligations are reflected in Other long-term liabilities on the Consolidated Balance Sheet.
Other
The Company is subject to various legal or other proceedings that relate to the ordinary course of its business. The Company believes that the resolution of these proceedings, individually or in the aggregate, will not have a material adverse impact upon the Company’s consolidated financial statements.
On October 14, 2020, Garett Lucyk, et al. v. Materion Brush Inc., et. al., case number 20CV0234, a wage and hour purported collective and class action, was filed in the Northern District of Ohio against the Company and its subsidiary, Materion Brush Inc. (collectively, the Company). Plaintiff, a former hourly production employee at the Company's Elmore, Ohio facility, alleges that he and other similarly situated employees are not paid for all time they spend donning and doffing personal protective equipment in violation of the Fair Labor Standards Act and Ohio law. The case remains in the preliminary stages while the parties explore a negotiated resolution. The Company believes that it has substantive defenses and intends to vigorously defend this suit absent a negotiated resolution.
At December 31, 2021, the Company had outstanding letters of credit totaling $46.3 million related to workers’ compensation, consigned precious metal guarantees, environmental remediation issues, and other matters. The majority of the Company's outstanding letters of credit expire in 2022 and are expected to be renewed.

Accounting Policies [Abstract]  
Organization
Organization:  Materion Corporation (the Company) is a holding company with subsidiaries that have operations in the United States, Europe, and Asia. These operations manufacture advanced engineered materials used in a variety of end markets, including semiconductor, industrial, aerospace and defense, automotive, energy, consumer electronics, and telecom and data center. The Company has four reportable segments: Performance Alloys and Composites, Advanced Materials, Precision Optics, and Other. Other includes unallocated corporate costs.
Refer to Note C for additional segment details. The Company distributes its products through a combination of company-owned facilities and independent distributors and agents.
Business Combinations
Business Combinations: The Company records assets acquired and liabilities assumed at the date of acquisition at their respective fair values. Intangible assets acquired in a business combination are recognized and reported apart from goodwill. Goodwill represents the excess purchase price over the fair value of the tangible net assets and intangible assets acquired in a business combination. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
The amounts reflected in Note B are the results of the preliminary purchase price allocation for the HCS-Electronic Materials acquisition and will be updated upon completion of the final valuation. The Company is required to complete the purchase price allocation within 12 months of the acquisition date. If such completion of the allocation results in a change in the preliminary values, the measurement period adjustment will be recognized in the period in which the adjustment amount is determined.
Use of Estimates Use of Estimates:  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.
Consolidation Consolidation:  The Consolidated Financial Statements include the accounts of Materion Corporation and its subsidiaries. All of the Company’s subsidiaries were wholly owned as of December 31, 2021. Intercompany accounts and transactions are eliminated in consolidation.
Cash Equivalents Cash Equivalents:  All highly liquid investments with a maturity of three months or less when purchased are considered to be cash equivalents.
Accounts Receivable Accounts Receivable:  An allowance for doubtful accounts is maintained for the expected losses resulting from the inability of customers to pay amounts due. The Company considers the current market conditions and credit losses related to the Company's trade receivables based on the macroeconomic environment, geographic considerations, and other expected market trends. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns, and other analyses of historical data and trends. Accounts receivable were net of an allowance for credit losses of $0.5 million at both December 31, 2021 and 2020. The change in the allowance for credit losses includes expense and net write-offs, neither of which were material. The Company extends credit to customers based upon their financial condition, and collateral is not generally required.
Inventories Inventories: Inventories are stated at lower of cost or net realizable value. All of the Company's inventories, except for its bertrandite ore mine which values inventory using a weighted average cost method, including raw materials, manufacturing supplies inventory as well as international (outside the U.S.) inventories, have been valued using the first-in, first-out (FIFO) method as of December 31, 2021 and 2020.
Property, Plant and Equipment
Property, Plant, and Equipment:  Property, plant, and equipment is stated on the basis of cost. Depreciation is computed principally by the straight-line method, except certain assets for which depreciation may be computed by the units-of-production method. The depreciable lives that are used in computing the annual provision for depreciation by class of asset are primarily as follows:
 Years
Land improvements
10 to 20
Buildings
20 to 40
Leasehold improvementsLife of lease
Machinery and equipment
3 to 15
Furniture and fixtures
4 to 10
Automobiles and trucks
3 to 8
Research equipment
3 to 10
Computer hardware
3 to 10
Computer software
3 to 10
An asset acquired under a finance lease will be recorded at the lesser of the present value of the projected lease payments or the fair value of the asset and will be depreciated in accordance with the above schedule. Leasehold improvements will be depreciated over the life of the improvement if it is shorter than the life of the lease. Repair and maintenance costs are expensed as incurred.
Mineral Resources and Mine Development
Mineral Resources and Mine Development: Property acquisition costs are capitalized as mineral resources on the balance sheet and are depleted using the units-of-production method based upon total estimated recoverable proven reserves of the beryllium-bearing bertrandite ore body. The Company uses beryllium pounds as the unit of accounting measure, and depletion expense is recorded on a pro-rata basis based upon the amount of beryllium pounds extracted as a percentage of total estimated beryllium pounds contained in the ore body.
Mine development costs at our open pit surface mines include drilling, infrastructure, other related costs to delineate an ore body and the removal of overburden to initially expose an ore body. Costs incurred before mineralization is classified as proven and probable reserves are expensed and classified as exploration expense. Capitalization of mine development project costs, that meet the definition of an asset, begins once mineralization is classified as proven and probable reserves.
In 2020, the Company expanded a mine to further develop an ore body. Since the pre-production phase ended when ore was first extracted from this mine, the Company recognized approximately $12.9 million of mine development costs in 2020 as a component of cost of sales. This expansion is expected to benefit future periods.
The cost of removing overburden and waste materials to access the ore body at an open-pit mine prior to the production phase is capitalized during the development of an open-pit mine and are capitalized at each pit. These costs are amortized as the ore is extracted using the units-of-production method based upon total estimated recoverable proven reserves for the individual pit. The Company uses beryllium pounds as the unit of accounting measure for recording amortization.
To the extent that the aforementioned costs benefit an entire ore body, the costs are amortized over the estimated useful life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block area.
Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of costs applicable to sales. All other drilling and related costs are expensed as incurred.
Goodwill and Other Intangible Assets Goodwill and Other Intangible Assets:  Goodwill is reviewed annually for impairment or more frequently if impairment indicators arise. The Company conducts its annual goodwill and indefinite-lived intangible asset impairment assessment as of the first day of the fourth quarter, or more frequently under certain circumstances. For the purpose of the goodwill impairment assessment, the Company has the option to perform a qualitative assessment (commonly referred to as "step zero") to determine whether further quantitative analysis of impairment of goodwill or indefinite-lived intangible assets is necessary or a quantitative assessment ("step one") where the Company estimates the fair value of each reporting unit using a discounted cash flow method (income approach). Goodwill is assigned to the reporting unit, which is the operating segment level or one level below the operating segment. Intangible assets with finite lives are amortized using the straight-line method or effective interest method, as applicable, over the periods estimated to be benefited, which is generally 20 years or less. Finite-lived intangible assets are also reviewed for impairment if facts and circumstances warrant.
Long-Lived Asset Impairment Long-Lived Asset Impairment: Management performs impairment tests of long-lived assets, including property and equipment, whenever an event occurs or circumstances change that indicate that the carrying value may not be recoverable or the useful life of the asset has changed. Upon indications of impairment, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The asset group would be considered impaired when the estimated future undiscounted cash flows generated by the asset group are less than its carrying value.  If such undiscounted cash flows indicate that the carrying value of the asset group is not recoverable, impairment losses are measured by comparing the estimated fair value of the asset group to its carrying amount.
Derivatives Derivatives:  The Company recognizes all derivatives 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, a component of shareholders’ equity, until the hedged item is recognized in earnings. If the derivative is designated as a fair value hedge, changes in fair value are offset against the change in the fair value of the hedged asset, liability, or commitment through earnings. The ineffective portion of a derivative’s change in fair value, if any, is recognized in earnings immediately. If a derivative is not a hedge, changes in its fair value are adjusted through the income statement.
Asset Retirement Obligation Asset Retirement Obligation:  The Company records a liability to recognize the legal obligation to remove an asset at the time the asset is acquired or when the legal liability arises. The liability is recorded for the present value of the ultimate obligation by discounting the estimated future cash flows using a credit-adjusted risk-free interest rate. The liability is accreted over time, with the accretion charged to expense. An asset equal to the fair value of the liability is recorded concurrent with the liability and depreciated over the life of the underlying asset.
Unearned Income
Unearned Income:  Expenditures for capital equipment to be reimbursed under government contracts are recorded in property, plant, and equipment, while the reimbursements for those expenditures are recorded in unearned income, a liability on the balance sheet. When the assets subject to reimbursement are placed in service, the total cost is depreciated over the useful lives, and the unearned income liability is reduced and credited to cost of sales on the Consolidated Statements of Income ratably with the annual depreciation expense.
Also included in Unearned Income as of December 31, 2021 and 2020, are $72.6 million and $58.8 million, respectively, of customer prepayments. See Note L for additional discussion.
Advertising Costs Advertising Costs: The Company expenses all advertising costs as incurred. Advertising costs were $0.3 million in 2021, $0.3 million in 2020, and $0.7 million in 2019.
Stock-based Compensation Stock-based Compensation:  The Company recognizes stock-based compensation expense based on the grant date fair value of the award over the period during which an employee is required to provide service in exchange for the award. Stock-based awards include performance-based restricted stock units (PRSUs), restricted stock units (RSUs), and stock appreciation rights (SARs). The fair value of PRSUs and RSUs is primarily based on the closing market price of a share of the Company's common stock on the date of grant, modified as appropriate to take into account the features of such grants. SARs are granted with an exercise price equal to the closing price of the Company's common shares on the date of grant. The fair value of SARs is determined using a Black-Scholes option-pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate, and the expected dividend yield. The portion of the PRSU awards that are valued based on the Company's total shareholder return as compared to peers is valued using Monte Carlo simulations, which incorporates assumptions regarding the expected volatility, the expected correlation, and the risk-free interest rate. See Note R for additional information about stock-based compensation.
Capitalized Interest Capitalized Interest: Interest expense associated with active capital asset construction and mine development projects is capitalized and amortized over the future useful lives of the related assets.
Income Taxes Income Taxes:  The Company uses the liability method in measuring the provision for income taxes and recognizing deferred tax assets and liabilities on the balance sheet. The Company will record a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized, as warranted by current facts and circumstances. The Company applies a more-likely-than-not recognition threshold for all tax uncertainties and will record a liability for those tax benefits that have a less than 50% likelihood of being sustained upon examination by the taxing authorities.
Net Income Per Share Net Income Per Share:  Basic earnings per share (EPS) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the assumed conversion of all dilutive common stock equivalents as appropriate using the treasury stock method.
New Pronouncements Adopted New Pronouncements Adopted:  In November 2020, the Securities Exchange Commission (SEC) issued the SEC Final Rule Release No. 33-10890, Management’s Discussion and Analysis, Selected Financial Data, and Supplementary Financial Information, which simplifies Management’s Discussion and Analysis (MD&A) and certain financial disclosure requirements in SEC regulation S-K. The final rule eliminates Regulation S-K, Item 301, “Selected Financial Data”, simplifies Regulation S-
K, Item 302, “Supplementary Financial Information”, and amends certain aspects of Regulation S-K, Item 303, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. The Company adopted the standard on December 31, 2021. The adoption did not materially impact the Company's financial statements or disclosures.
In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires companies to apply ASC 606 on the acquisition date to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. This is an exception to the recognition and measurement principle in ASC 805 which generally requires an acquirer to recognize and measure the assets it acquires and the liabilities it assumes at fair value on the acquisition date. For public entities, the guidance is effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. The Company has early adopted this guidance and has applied it to the accounting for contract assets and contract liabilities acquired as part of the HCS-Electronic Materials (as defined in Note B) acquisition.
New Accounting Guidance Issued and Not Yet Adopted: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. The Company does not expect the transition away from LIBOR to have a material impact on interest expense or on the 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, Policy 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 its promise to transfer the associated products. Accordingly, customer payments for 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 December 31, 2021. Remaining performance obligations include non-cancelable 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 December 31, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $81.9 million.
Contract Costs: The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs primarily relate to sales commissions, which are included in selling, general, and administrative expenses.
Contract Balances: The timing of revenue recognition, billings, and cash collections resulted in the following contract assets and contract liabilities:
(Thousands)December 31, 2021December 31, 2020$ change% change
Accounts receivable, trade
$213,584 $156,821 $56,763 36 %
Unbilled receivables
7,961 8,832 (871)(10)%
Unearned revenue
7,770 7,713 57 %
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 2021.
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. The Company recognized approximately $6.8 million of the December 31, 2020 unearned amounts as revenue during 2021. The Company recognized approximately $3.2 million of the December 31, 2019 unearned amounts as revenue during 2020.

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.
