| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. In 2021, the Company reclassified its research and development costs and intangible asset amortization expense out of selling, general and administrative expenses to distinct line items on the income statement. The Company updated the presentation of the earliest years presented on the Consolidated Statement of Operations to conform to this presentation. Following the sale of the Company's Distribution business in 2019, the Company operated as one segment. In the fourth quarter of 2021, our Chief Operating Decision Maker ("CODM") established a new structure for the Company to better align the Company's businesses to support capital allocation plans, portfolio management and growth. This new structure resulted in the introduction of three reportable segments: Engineered Products, Precision Products and Structures. See Note 4, Segment and Geographic Information , for 2021 financial results by segment and a recast of financial results by segment for fiscal years 2020 and 2019. During the fourth quarter of 2020, the Company committed to a plan and received approval from its Board of Directors to sell its United Kingdom ("UK") Composites division. As a result of the approved plan, the UK Composites division met the criteria set forth in ASC 205-20, Presentation of Financial Statements - Discontinued Operations ("ASC 205-20"). for held for sale. At December 31, 2020, the assets of the UK Composites business were considered impaired as the estimated fair value of the disposal group was lower than the estimated carrying value of the UK Composites business. As a result, $24.3 million in assets were written off and the remaining loss related to the anticipated sale of the disposal group of $12.0 million was accrued for in liabilities held for sale, current portion on the Company's Consolidated Balance Sheets, resulting in a total loss of $36.3 million recorded to impairment on assets held for sale on the Company's Consolidated Statement of Operations in the year ended December 31, 2020. The related liabilities of the UK division to be sold were reclassified to liabilities held for sale, respectively, as of December 31, 2020 on the Company's Consolidated Balance Sheets. The Company sold its UK Composites division in a transaction that closed on February 2, 2021. An additional loss of $0.2 million was recorded to loss (gain) on sale of business in the year ended December 31, 2021. See Note 2, Disposals , to the Consolidated Financial Statements for further information. During the third quarter of 2019, the Company completed the sale of its Distribution business for total cash consideration of $700.0 million, excluding certain working capital adjustments and transaction costs. The Distribution business' results of operations and the related cash flows have been reclassified to earnings from discontinued operations in the Consolidated Statements of Operations and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented. See Note 2, Disposals , to the Consolidated Financial Statements for further information. |
| Use of Estimates | Use of Estimates The preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include the carrying amount of property, plant and equipment, goodwill and other intangible assets; valuation allowances for receivables, inventories and income taxes; valuation of share-based compensation; assets and obligations related to employee benefits; and accounting for long-term contracts including claims. Actual results could differ from those estimates. |
| Foreign Currency Translations | Foreign Currency Translation The Company has certain operations outside the United States that prepare financial statements in currencies other than the U.S. dollar. For these operations, results of operations and cash flows are translated using the average exchange rate throughout the period. Assets and liabilities are generally translated at end of period rates. The gains and losses associated with these translation adjustments are included as a component of accumulated other comprehensive income (loss) in shareholders’ equity. |
| Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of trade accounts receivable. The carrying amounts of these items, as well as trade accounts payable and notes payable, approximate fair value due to the short-term maturity of these instruments. At December 31, 2021, no individual customer accounted for more than 10% of consolidated accounts receivable. At December 31, 2020, one individual customer accounted for more than 10% of consolidated accounts receivable. In the year ended December 31, 2021, two individual customers, the U.S. Government ("USG") and a Joint Programmable Fuze ("JPF") direct commercial sales ("DCS") customer, accounted for more than 10% of consolidated net sales. In the year December 31, 2020, three individual customers, the USG, The Boeing Company and a JPF DCS customer, accounted for more than 10% of consolidated net sales. In both 2021 and 2020, sales to the USG were primarily made by the Engineered Products and Precision Products segment, while sales to a JPF DCS customer were made by the Precision Products segment. In 2020, sales to The Boeing Company were made by all three segments. Foreign sales were approximately 41.6%, 50.0% and 44.4% of the Company’s net sales in 2021, 2020 and 2019, respectively, and are concentrated in the Middle East, Germany, Canada, United Kingdom, New Zealand, Switzerland and France. |
| Additional Cash Flow Information | Additional Cash Flow Information Non-cash investing activities in 2021 include an accrual of $2.0 million for purchases of property and equipment. Non-cash financing activities in 2021 include an adjustment to other comprehensive income related to the underfunding of the pension and SERP plans. The total net adjustment was $9.9 million, net of tax of $2.9 million. Additionally, non-cash financing activities in 2021 include $5.6 million of dividends declared but not yet paid. Non-cash financing activities in 2020 include an adjustment to other comprehensive income related to the underfunding of the pension and SERP plans. The total net adjustment was $4.4 million, net of tax of $1.3 million. Additionally, non-cash financing activities in 2020 include $5.5 million of dividends declared but not yet paid. Non-cash investing activities in 2019 include an accrual of $0.8 million for purchases of property and equipment (including finance lease obligations), $4.0 million in working capital adjustments associated with the sale of the Distribution business and the write-off of the $4.0 million note receivable associated with the sales of the UK Tooling business as it was deemed not likely to be collected. Additionally, in 2019, the Company repurchased a K-MAX® aircraft from a customer who was simultaneously purchasing a new aircraft to support the development of the Company's unmanned aircraft system. The repurchased aircraft was used to settle a portion ($3.1 million) of the purchase price on the customer's new K-MAX® aircraft. Non-cash financing activities in 2019 include an adjustment to other comprehensive income related to the underfunding of the pension and SERP plans. The total net adjustment was $8.9 million, net of tax of $2.6 million. Additionally, non-cash financing activities in 2019 include $5.6 million of dividends declared but not yet paid and an accrual of $1.7 million for purchases of treasury shares. The Company describes its pension obligations in more detail in Note 17, Pension Plans . |
| Revenue Recognition | Revenue Recognition Under Accounting Standard Codification ("ASC") 606, the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies the following five step approach: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to performance obligations in the contract; and (5) recognize revenue when or as a performance obligation is satisfied. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Revenue Recognition - continued A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation when they are a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the most likely amount method. Determining the transaction price requires significant judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company's contracts with customers generally do not include significant financing components or non-cash consideration. In certain instances, the Company has accounted for contracts using the portfolio approach, a practical expedient permissible under the standard. The determination of when the use of the portfolio approach is appropriate requires judgment from management based on consideration of all the facts and circumstances. The Company uses the portfolio approach when the effect of accounting for a group of contracts or a group of performance obligations would not differ materially from considering each contract or performance obligation separately. This determination requires the use of estimates and assumptions that reflect the size and composition of the portfolio. The Company primarily uses the portfolio approach for its commercial and defense bearings and structures businesses. The Company's primary criteria considered when using the portfolio approach is the commonality of economic factors, which generally follow the product type based on consistent production costs and standard pricing for the products. To determine the appropriate revenue recognition model for long-term contracts, the Company evaluates whether a contract exists, considering whether multiple contracts should be combined as one single contract and then whether the contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment, as these decisions could change the amount of revenue and profit recorded in a given period. For certain programs, the Company may promise to provide distinct goods or services within a contract, in which case these are separated into more than one performance obligation. For certain programs, the Company recognizes revenue over time because of continuous transfer of control to the customer. For USG contracts, this continuous transfer of control to the customer is supported by clauses in the contract that provide lien rights to the customer over the work in progress, thereby control transfers as costs are incurred. For non-USG contracts, the customer typically controls the work in progress because the Company is producing products that do not have an alternative use to the Company and where contractual termination clauses provide the Company rights to payment for work performed to date plus a reasonable profit. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Revenue Recognition - continued Revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the cost-to-cost measure of progress for its contracts because it best depicts the transfer of assets to the customer which occurs as cost is incurred under the contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Total estimated contract costs generally include labor, materials and subcontractors’ costs, other direct costs and related overhead costs. These estimates also include the estimated cost of satisfying offset obligations, as required under certain contracts. The complexity of certain programs as well as technical risks and uncertainty as to the future availability of materials and labor resources could affect the Company’s ability to accurately estimate future contract costs. For contracts that recognize revenue over time, the Company performs detailed quarterly reviews of the progress and execution of its performance obligations under these contracts. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the schedule (e.g. the number and type of milestone events), technical requirements (e.g., a newly-developed product versus a mature product) and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation (e.g. to estimate increases in wages and prices for materials and related support cost allocations), execution by subcontractors, the availability and timing of funding from customers and overhead cost rates, among other variables. Based upon these reviews, the Company will record the effects of adjustments in profit estimates each period. If at any time management determines that in the case of a particular contract total costs will exceed total contract revenue, a provision for the entire anticipated contract loss is recorded at that time. The Company recognized reductions in revenue of $2.6 million and $7.0 million in the years ended December 31, 2021 and 2020, respectively, due to changes in profit estimates. These decreases were primarily related to cost growth on certain legacy fuzing contracts and certain structures contracts, partially offset by favorable cost performance on the JPF contract with the USG. The Company recognized as reduction in revenue in the year ended December 31, 2019 of $4.6 million due to a change in profit estimates. This decrease was primarily related to cost growth on the SH-G program with Peru, a certain legacy fuzing contract and certain structures contracts, partially offset by favorable cost performance on the JPF contract with the USG. Due to the nature of the work required to be performed on many of the Company's performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. From time-to-time the Company enters into long-term contracts with the USG and other customers that contain award fees, incentive fees or other provisions that can either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. The Company estimates variable consideration at the most likely amount to which it expects to be entitled. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company does not include financing components as variable consideration if less than one year. At December 31, 2021, the Company did not have any significant financing components. Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new or makes changes to the existing enforceable rights and obligations. Contract modifications for goods or services that are not distinct from the existing contract are accounted for as if they were part of that existing contract. In these cases, the effect of the contract modification on the transaction price and the measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis, except when such modifications relate to a performance obligation that is a series of substantially the same distinct goods or services. If the modification relates to a performance obligation for a series of substantially the same distinct goods or services, the modification is treated prospectively. Contract modifications for goods or services that are considered distinct from the existing contract are accounted for as separate contracts. The Company applied the practical expedient for any contracts that were modified prior to January 1, 2018; therefore, the contracts were not restated retrospectively for those modifications. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Revenue Recognition - continued For other contracts, excluding the long-term contracts discussed above, the method of revenue recognition remained substantially the same under ASC 606. For these contracts, revenue is primarily recognized at the point in time when the title transfers to the customer, as this is when the performance obligation is controlled by the customer. Additionally, a small percentage of revenue related to certain contracts for repairs and overhauls is accounted for over time under ASC 606. Under these contracts, revenue is generally recognized as work is performed in proportion to the actual costs incurred as compared to total estimated contract costs. |
| Cost of Sales and Selling, General and Administrative Expenses | Cost of Sales and Selling, General and Administrative Expenses Cost of sales includes costs of products and services sold (i.e., purchased product, raw material, direct labor, engineering labor, outbound freight charges, depreciation and amortization, indirect costs and overhead charges). Selling expenses primarily consist of advertising, promotion, bid and proposal, employee payroll and corresponding benefits and commissions paid to sales and marketing personnel. General and administrative expenses primarily consist of employee payroll including executive, administrative and financial personnel and corresponding benefits, incentive compensation, consulting expenses, warehousing costs, and depreciation. Legal costs are expensed as incurred and are generally included in general and administrative expenses. In 2021, the Company reclassified its research and development costs and intangible asset amortization expense out of selling, general and administrative expenses to distinct line items on the income statement. The Company updated the presentation of the earliest years presented on the Consolidated Statement of Operations to conform to this presentation. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term cash investments. These investments are liquid in nature and have original maturities of three months or less. The Company's cash and cash equivalents at December 31, 2021 and 2020 included $65.5 million and $51.5 million of Level 1 (quoted prices in active markets for identical assets or liabilities) money market funds. On January 3, 2020, the Company acquired all of the equity interests of Bal Seal. Upon closing, the Company funded $24.7 million associated with Bal Seal's employee retention plans into escrow accounts. This amount and related interest was included in restricted cash on the Company's Consolidated Balance Sheets as of December 31, 2020. Eligible participants received an allocation of the escrow balance one year following the acquisition date. Bank overdraft positions, which occur when total outstanding issued checks exceed available cash balances at a single financial institution at the end of a reporting period, are reclassified to other current liabilities within the consolidated balance sheets. At December 31, 2021 and 2020, the Company had bank overdrafts of $1.4 million and $1.6 million, respectively, included in other current liabilities. |
| Accounts Receivable | Accounts Receivable The Company has three types of accounts receivable: (a) Trade receivables, which consist of amounts billed and currently due from customers; (b) USG contracts, which consist of (1) amounts billed, and (2) costs and accrued profit – not billed; and (c) Commercial and other government contracts, which consist of (1) amounts billed, and (2) costs and accrued profit – not billed. The Company's receivables, net, consist of amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. |
| Contract with Customer, Asset | Contract Assets The Company's contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is applied and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts do not exceed their net realizable value. Contract assets are generally classified as current as such amounts are billable and collectible within twelve months. |
| Capitalized Contract Cost | Contract Costs Contract costs consist of costs to obtain and fulfill a contract. Costs to fulfill a contract primarily consist of nonrecurring engineering costs incurred at the start of a new program for which such costs are expected to be recovered under existing and future contracts. Such costs are amortized over the estimated revenue amount of the contract. Costs to obtain a contract consist of commissions and agent fees paid in connection with the award of a contract. If these costs are determined to have an amortization period of less than one year, the Company applies the practical expedient and the related costs are expensed as incurred. If the amortization period is determined to be greater than a year and the incremental costs to obtaining the contract qualify as an asset, then the contract costs are recorded and amortized over the estimated contract revenue. |
| Inventories | Inventories The Company has the following types of inventory: (a) raw materials, (b) contracts in process and other work in process, and (c) finished goods. Raw material includes certain general stock materials but primarily relates to purchases that were made in anticipation of specific programs for which production has not been started as of the balance sheet date. Raw materials are stated at the lower of the cost of the inventory or its fair market value. Contracts in process and other work in process and finished goods are valued at production cost represented by raw material, labor and overhead. Contracts in process and other work in process and finished goods are not reported at amounts in excess of net realizable values. |
| Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment is recorded at cost. Depreciation is computed primarily on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives for buildings generally range from 15 to 40 years and for leasehold improvements range from 1 to 20 years, whereas machinery, office furniture and equipment generally have useful lives ranging from 3 to 15 years. At the time of retirement or disposal, the acquisition cost of the asset and related accumulated depreciation are eliminated and any gain or loss is credited to or charged against income. Long-lived assets, such as property, plant and equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of the asset. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Maintenance and repair items are charged against income as incurred, whereas renewals and betterments are capitalized and depreciated. Leasing The Company accounts for leases in accordance with ASC 842, Leases. Under ASC 842, the Company determines if a contract contains a lease at the inception date of the contract. To determine if the contract contains a lease, the Company evaluates if there is an identified asset in the contract and if the Company has control over the use of the identified asset. The Company has elected not to apply the recognition requirements of ASC 842 to short-term leases (leases that, at the commencement date, have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise) as permissible under the standard. For short-term leases, the Company recognizes lease payments on a straight-line basis and variable payments in the period in which the obligation for those payments is incurred. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Leasing - continued The Company must classify each lease as a finance lease or an operating lease. The Company's finance leases are included in machinery, office furniture and equipment and construction in process. Amortization of these assets is included in depreciation and amortization expense. The Company's operating leases consist of rent commitments under various leases for office space, warehouses, land and buildings. At the commencement date, the right-of-use asset and lease liability are recorded to the Company's Consolidated Balance Sheets when the Company obtains control of the use of the asset. Lease liabilities are recognized at commencement based on the present value of the unpaid lease payments over the lease term. The initial measurement of the right-of-use asset is equal to the total of the initial measurement of the lease liability, incremental costs to obtain the lease and prepaid lease payments, less any lease incentives received. Some of the Company's leases have fixed amount rent escalations or contingent rent that are recognized on a straight-line basis over the entire lease term. Material leasehold improvements and other landlord incentives are amortized over the shorter of their economic lives or the lease term, including renewal periods, if reasonably assured. Substantially all real estate taxes, insurance and maintenance expenses associated with leased facilities are obligations of the Company. The Company elected the practical expedient allowing the Company to combine lease and non-lease components by class as a single lease component for its real estate leases. Nonlease components for the Company's vehicles and other equipment leases are not material. The Company uses the discount rate implicit in a lease contract, if available. As most of the Company's leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Certain leases are renewable for varying periods and certain leases including options to terminate the leases. For renewal options, the Company performs an assessment at commencement if it is reasonably likely to exercise the option. The assessment is based on the Company's intentions, past practices, estimates and factors that create an economic incentive for the Company. Generally, the Company is not reasonably certain to exercise the renewal option in a lease contract as it performs an assessment for most real estate leases within six months prior to termination comparing the renewal rents under the option with the fair market returns for equivalent property under similar terms and conditions. Although the Company does not historically change locations often, it is not reasonably certain the Company will exercise the renewal option; therefore, the periods covered by the renewal option are not typically included in the lease term at commencement. While some of the Company's leases include options allowing early termination of the lease, the Company historically has not terminated its lease agreements early unless there is an economic, financial or business reason to do so; therefore, the Company does not typically consider the termination option in its lease term at commencement. |
| Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill represents the excess of the aggregate purchase price over the fair value of the net identifiable assets acquired in a purchase business combination and is reviewed for impairment at least annually. ASC Topic 350, "Intangibles - Goodwill and Other," ("ASC 350") permits the assessment of qualitative factors to determine whether events and circumstances lead to the conclusion that it is necessary to perform the quantitative goodwill impairment test required under ASC 350. The qualitative assessment management performs takes into consideration the following factors: general economic conditions, industry specific performance, changes in carrying values of the reporting units or asset groups, the assessment of assumptions used in the previous fair value calculation and changes in transaction multiples. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Goodwill and Other Intangible Assets - continued In the quantitative goodwill impairment test, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. Fair value of the reporting unit is determined using an income methodology based on management’s estimates of forecasted cash flows for each reporting unit, with those cash flows discounted to present value using rates commensurate with the risks associated with those cash flows. In addition, management uses a market-based valuation method involving analysis of market multiples of revenues and earnings before interest, taxes, depreciation and amortization ("EBITDA") for (i) a group of comparable public companies and (ii) recent transactions, if any, involving comparable companies. Goodwill and intangible assets with indefinite lives are evaluated annually for impairment in the fourth quarter, based on annual forecast information. Intangible assets with finite lives are amortized over their estimated period of benefit. Goodwill and other intangible assets are reviewed for possible impairment whenever changes in conditions indicate that the fair value of a reporting unit is more likely than not below its carrying value. During the third quarter of 2020, the Company identified a triggering event for possible impairment for the Aerosystems reporting unit based on a decline in earnings compared to forecasts used in prior periods and updated forecasts, which indicated the forecasted cash flows for this reporting unit were lower than amounts previously forecasted. Management performed a quantitative analysis on the Aerosystems reporting unit using an income methodology based on estimates of forecasted cash flows, with those cash flows discounted to present value using rates commensurate with the risks associated with those cash flows. In addition, management used a market-based valuation method involving analysis of market multiples of revenues and earnings before interest, taxes, depreciation and amortization ("EBITDA") for (i) a group of comparable companies and (ii) recent transactions, if any, involving comparable companies. The quantitative analysis resulted in a conclusion that the fair value of the Aerosystems reporting unit was $56.1 million below its carrying value. In the year ended December 31, 2020, the Company recorded a goodwill impairment charge of $50.3 million for the Aerosystems reporting unit, which represented the entire goodwill balance for the reporting unit. No such charges were recorded in 2021 or 2019. In the fourth quarter of 2020, the Company committed to a plan and received approval from its Board of Directors to sell its UK Composites division. At December 31, 2020, the assets of the UK Composites business were considered impaired as the estimated fair value of the disposal group was lower than the estimated carrying value of the UK Composites business. As a result, $24.3 million in assets were written off and the remaining loss related to the anticipated sale of the disposal group of $12.0 million was accrued for in liabilities held for sale, current portion on the Company's Consolidated Balance Sheets, resulting in a total loss of $36.3 million recorded to impairment on assets held for sale on the Company's Consolidated Statements of Operations in the year ended December 31, 2020. Of this amount, $22.9 million related to the cumulative translation adjustment balance for the UK Composites division. The Company sold its UK Composites business in a transaction that closed on February 2, 2021. An additional loss of $0.2 million was recorded to loss (gain) on sale of business in the year ended December 31, 2021. |
| Debt, Policy | Debt The Company relies on bank financing as an important source of liquidity for its business activities. Outstanding debt is classified as current or long-term based on the maturity of the Company's financing arrangements. Current and long-term debt balances are reported net of debt issuance costs. See Note 14, Debt , for further information on the Company's financing arrangements. |
| Contract with Customer, Liability | Contract Liabilities The Company's contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. Advance payments and billings in excess of revenue recognized are classified as current or noncurrent based on the timing of when recognition of revenue is expected. |
| Unfulfilled Performance Obligations | Unfulfilled Performance Obligations Unfulfilled performance obligations ("backlog") represents the transaction price of firm orders for which work has not been performed and excludes unexercised contract options and potential orders under ordering-type contracts. As of December 31, 2021, the aggregate amount of the transaction price allocated to backlog was $700.9 million. The Company expects to recognize revenue on approximately $409.3 million of this amount over the next 12 months, with the remaining amount to be recognized thereafter. At December 31, 2020, the aggregate amount of the transaction price allocated to backlog was $631.2 million. |
| Self-Insured Retentions | Self-Insured Retentions To limit exposure to losses related to group health, workers’ compensation, auto and product general liability claims, the Company obtains third-party insurance coverage. The Company has varying levels of deductibles for these claims. The total liability/deductible for group health is limited to $0.3 million per claim, workers’ compensation is limited to $0.4 million per claim and for product/general liability the limit is $0.3 million per claim. The Company pays a fixed premium for its auto liability policy; therefore, there is no deductible on claims. The cost of such benefits is recognized as expense based on claims filed in each reporting period and an estimate of claims incurred but not reported (“IBNR”) during such period. The estimates for the IBNR are based upon historical trends and information provided to us by the claims administrators, and are periodically revised to reflect changes in loss trends. These amounts are included in other current liabilities on the Consolidated Balance Sheets. Liabilities associated with these claims are estimated in part by considering historical claims experience, severity factors and other actuarial assumptions. Projections of future losses are inherently uncertain because of the random nature of insurance claim occurrences and the potential for differences between actual developments and actuarial assumptions. Such self-insurance accruals will likely include claims for which the ultimate losses will be settled over a period of years. |
| Research and Development | Research and DevelopmentResearch and development expenses include laboratory research; concept development; design, testing and modification of possible products or processes; design of tools for new technology and engineering activity required to advance development. Costs not specifically covered by contracts are recognized as expense as incurred and included in research and development costs on the Company's Consolidated Statements of Operations. In 2021, the Company reclassified its research and development costs out of selling, general and administrative expenses to a distinct line item on the income statement. The Company updated the presentation of the earliest years presented on the Consolidated Statement of Operations to conform to this presentation. Customer funded research expenditures (which are included in cost of sales) were $0.4 million in 2021, $0.1 million in 2020 and $0.6 million in 2019. |
| Income Taxes | Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates was recognized in income in the period that includes the enactment date. The deferred income taxes were significantly impacted by the enactment of the Tax Cuts and Jobs Act of 2017 ("Tax Reform"). The adjustments to deferred income taxes resulted in stranded tax effects of items within accumulated other comprehensive income. In 2019, the Company elected to reclassify the stranded tax effects to retained earnings from accumulated other comprehensive income using the item-by-item approach. The Company records a benefit for uncertain tax positions in the financial statements only when it determines it is more likely than not that such a position will be sustained upon examination by taxing authorities based on the technical merits of the position. Unrecognized tax benefits represent the difference between the position taken in the tax return and the benefit reflected in the financial statements. |
| Share-Based Payment Arrangements | Share-Based Payment Arrangements The Company records compensation expense for share-based awards based upon an assessment of the grant date fair value of the awards. The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model. A number of assumptions are used to determine the fair value of options granted. These include expected term, dividend yield, volatility of the options and the risk free interest rate. In 2021, the Company modified its long-term incentive program to increase the emphasis on equity. Beginning in the first quarter of 2021, the long-term incentive awards granted consist of a combination of service-based restricted stock awards ("RSAs") and performance stock units ("PSUs") which are intended to be settled in shares, as opposed to cash-based awards that had been utilized in the past. The number of PSUs that will vest will be determined based on total shareholder return ("TSR") and return on total invested capital ("ROIC") over a three-year performance period, each of which will remain equally weighted in determining payouts. The fair value of the PSUs based on TSR is estimated on the date of grant using a Monte-Carlo simulation model. A number of assumptions are used to determine the fair value of the PSUs granted, including expected term, volatility, the risk-free interest rate and dividend yield. See Note 22, Share-Based Arrangements, for further information. |
| Environmental Costs, Policy | Environmental Remediation The Company is subject to environmental regulation by federal, state and local authorities in the United States and regulatory authorities with jurisdiction over its foreign operations. When the Company becomes aware of environmental risk, it performs a site study to ascertain the potential magnitude of contamination and the estimated cost of remediation. Environmental costs are accrued when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site. Conditions of the site must be monitored throughout the remediation process as numerous factors could affect the estimated liability. The Company evaluates the identified environmental issues to ensure the time to complete the remediation and the total cost of remediation are consistent with the initial estimate. If there is any change in the cost and/or timing of remediation, the accrual is adjusted accordingly. See Note 13, Environmental Costs , and Note 19, Commitments and Contingencies , for further information. |
| Derivative Financial Instruments | Derivative Financial Instruments The Company is exposed to certain risks relating to its ongoing business operations, including market risks relating to fluctuations in foreign currency exchange rates and interest rates. Derivative financial instruments are recognized on the Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in the fair values of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedged transaction. Gains and losses on derivative instruments reported in accumulated other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not offset fair value amounts of derivative instruments. The Company does not use derivative instruments for speculative purposes. See Note 9, Derivative Financial Instruments , for further information. |
| Pension Accounting | Pension Accounting The Company accounts for its defined benefit pension plan by recognizing the overfunded or underfunded status of the plan, calculated as the difference between the plan assets and the projected benefit obligation, as an asset or liability on the balance sheet, with changes in the funded status recognized in comprehensive income in the year in which they occur. Expenses and liabilities associated with the plan are determined based upon actuarial valuations. Integral to the actuarial valuations are a variety of assumptions including expected return on plan assets and discount rate. The Company regularly reviews the assumptions, which are updated at the measurement date, December 31 st . The impact of differences between actual results and the assumptions are accumulated and generally amortized over future periods, which will affect expense recognized in future periods. The service cost component of net benefit cost is recorded in cost of sales and selling, general and administrative expenses separately from the other components of net benefit cost, which are recorded to non-service pension and postretirement benefit income. See Note 17, Pension Plans , for further information. |
| Recent Accounting Standards | Recent Accounting Standards Recent Accounting Standards Adopted In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, "Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes". The objective of the standard is to simplify the accounting for income taxes by removing certain exceptions and to improve consistent application of Topic 740 by clarifying and amending existing guidance. The standard update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the standard was permitted, including adoption in any interim period for which financial statements have not yet been issued. If early adopted in an interim period, the adjustments should be reflected as of the beginning of the annual period that includes that interim period. All amendments under the standard must be adopted in the same period. In 2021, the Company adopted ASU 2019-12 using the modified retrospective basis which resulted in a cumulative effect increase to retained earnings of $0.3 million. Recent Accounting Standards Yet to be Adopted In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers". The amendments in this standard update address diversity and inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination and require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. This standard update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the standard is permitted, including adoption in an interim period. The adoption of this standard update is not expected to have a material impact on the Company's consolidated financial statements; however, the impact will be dependent on future business combinations. In May 2021, the FASB issued ASU 2021-04, "Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Issuer's Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force)". The objective of this standard update is to clarify and reduce diversity in an issuer's accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The guidance clarifies whether an issuer should account for a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange as either an adjustment to equity and, if so, the related earnings per share ("EPS") effects, if any, or as an expense and, if so, the manner and pattern of recognition. The standard update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently assessing the potential impact this standard update could have on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity". The objective of this standard update is to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The update removes certain separation models between a debt component and equity or derivative component for certain convertible instruments, adds new disclosure requirements for convertible instruments to improve the decision usefulness and relevance of the information being provided to users of financial statements, clarifies the guidance for determining whether a contract qualifies for a scope exception from derivative accounting, and amends EPS guidance to improve consistency. The standard update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption of the standard is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. An entity should adopt the guidance as of the beginning of its annual fiscal year and can do so using a modified retrospective method or fully retrospective method of transition. The Company is currently assessing the potential impact this standard update could have on its consolidated financial statements. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Recent Accounting Standards Recent Accounting Standards Yet to be Adopted - continued 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". The objective of the standard is to address operational challenges likely to arise in accounting for contract modifications and hedge accounting due to reference rate reform. The amendments in this ASU provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The standard update is effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. Once elected for a topic or industry subtopic, the amendments in this standard update must be applied prospectively for all eligible contract modifications for that topic or industry subtopic. An entity may elect to apply the amendments for eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. If an entity elects to apply any of the amendments for an eligible hedging relationship existing as of the beginning of the interim period that includes March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of that interim period. If an entity elects to apply any of the amendments for a new hedging relationship entered into between the beginning of the interim period that includes March 12, 2020 and March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of the hedging relationship. In December 2021, the Company amended its credit agreement to move its LIBOR benchmark for non-USD borrowings to other non-USD benchmark rates. Future USD borrowings under this current Credit Agreement will continue be based on LIBOR. The impact of the adoption of this standard update is dependent on the Company's contracts modifications as a result of reference rate reform; however, the Company does not expect the adoption of the amendments associated with hedging relationships to have a material impact on the Company's consolidated financial statements. Subsequent to the issuance of ASU 2020-04, the FASB issued the following update: ASU 2021-01, "Reference Rate Reform (Topic 848) - Scope". The amendments in this update affect the guidance within ASU 2020-04 and are being assessed with ASU 2020-04. |
