Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies General: The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Consolidation: The accompanying consolidated financial statements include the accounts of the Company and all of its subsidiaries. Intercompany transactions and account balances have been eliminated. Revenue recognition: The Company accounts for revenue in accordance with Accounting Standard Codification 606, Revenue from Contracts with Customers. Revenue is recognized by the Company when control of the product or solution is transferred to the customer. Control is generally transferred when products are shipped or delivered to customers, title is transferred, the significant risks and rewards of ownership have transferred, the Company has rights to payment and rewards of ownership pass to the customer. Customer acceptance may also be a factor in determining whether control of the product or solution has transferred. Although revenue is generally transferred at a point in time, a certain portion of businesses with customized products or contracts in which the Company performs work on customer-owned assets requires the use of an over time recognition model as certain contracts meet one or more of the established criteria pursuant to the accounting standards governing revenue recognition. Also, service revenue is recognized as control transfers, which is concurrent with the services being performed. See Note 3. Management fees related to the Aerospace Aftermarket Revenue Sharing Programs ("RSPs") are satisfied through an agreed upon reduction from the sales price of each of the related spare parts. These fees recognize our customer's necessary performance of engine program support activities, such as spare parts administration, warehousing and inventory management, and customer support, and are not separable from our sale of products, and accordingly, they are reflected as a reduction to sales, rather than as costs incurred, when revenues are recognized. Cash and cash equivalents: Cash in excess of operating requirements is generally invested in short-term, highly liquid, income-producing investments. All highly liquid investments purchased with an original maturity of three months or less are considered cash equivalents. Cash equivalents are carried at cost which approximates fair value. Accounts receivable: The Company records accounts receivable based on the net amount expected to be collected. Balances are reviewed regularly and reserves are adjusted when events or circumstances indicate carrying values may not be collectable. Inventories: Inventories are valued at the lower of cost, determined on a first-in, first-out basis, or net realizable value. The primary components of cost included in inventories are raw material, labor and overhead. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable value. The process for evaluating the value of excess and obsolete inventory often requires the Company to make judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be sold in the normal course of business and estimated costs. Accelerating the disposal process or changes in estimates based on future sales potential or estimated costs may necessitate future adjustments to these provisions. Property, plant and equipment: Property, plant and equipment is recorded at cost. Depreciation is recorded using a straight-line method of depreciation over estimated useful lives, generally ranging from 20 to 50 years for buildings and four to 12 years for machinery and equipment. The Company assesses the impairment of property, plant and equipment whenever events or changes in circumstances indicate the carrying value may not be recoverable. Business Combinations: In accordance with the Business Combinations guidance, acquisitions are recorded using the acquisition method of accounting. The Company includes the operating results of acquired entities from their respective dates of acquisition. The Company allocates the purchase consideration to the assets acquired and liabilities assumed in the acquired entity generally based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired and liabilities assumed in the acquired entity is recorded as goodwill. The primary items that generate goodwill include the increase in global market access and the acquired assembled workforce, neither of which qualify for recognition as an intangible asset. Costs incurred as a result of a business combination other than costs related to the issuance of debt or equity securities are recorded in the period the costs are incurred. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill. See Note 2. Goodwill: Goodwill represents the excess purchase price over the fair value of net assets of companies acquired in business combinations. Goodwill is considered an indefinite-lived asset. Goodwill is subject to impairment testing in accordance with accounting standards governing such on an annual basis, in the second quarter, or more frequently if an event or change in circumstances indicates that the fair value of a reporting unit has been reduced below its carrying value. The Company utilizes the option to first assess qualitative factors to determine whether it is necessary to perform the Step 1 quantitative goodwill impairment test in accordance with the applicable accounting standards. Under the qualitative assessment, management considers relevant events and circumstances including but not limited to macroeconomic conditions, industry and market considerations, overall reporting unit performance and events directly affecting a reporting unit. If the Company determines that the Step 1 quantitative impairment test is required, management estimates the fair value of the reporting unit using the income approach. Inherent in management’s development of cash flow projections are assumptions and estimates, including those related to forecasted revenue growth rates, forecasted operating margins, and the weighted average cost of capital. The Company compares the fair value of the reporting unit with the carrying value of the reporting unit. If the fair values were to fall below the carrying values, the Company would recognize a non-cash impairment charge to income from operations for the amount by which the carrying amount of any reporting unit exceeds the reporting unit’s fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. Based on our assessment as of April 1, 2023, the estimated fair value of the Automation reporting unit, which represents the 2018 acquisition of Gimatic, exceeded its carrying value, while the estimated fair value of each of the remaining reporting units significantly exceeded their carrying values. See disclosure related to Other Intangible Assets below and within Note 6. The Company also performed an annual assessment as of April 1, 2022, during the prior year period. The Company evaluated deteriorating macro-economic conditions subsequent to the date of the assessment, including inflationary pressures, rising interest rates, worsening global supply chain constraints and demand outlook, which materialized during the second quarter of 2022, impacting performance and outlook at Automation and resulted in a triggering event. Management revised its cash flow projections and weighted average cost of capital, resulting in a non-cash goodwill impairment charge of $68,194 related to the Automation reporting unit as the estimated fair value of the reporting unit declined below its carrying value. Management evaluated the significant increase in interest rates and further deteriorating macro-economic conditions that materialized during the fourth quarter of 2022, again resulting in a triggering event at Automation. Management performed a Step 1 quantitative assessment as of December 31, 2022 and concluded that there was no additional goodwill impairment at the business. The goodwill impairment charge was recorded in the three month period ended June 30, 2022. Leases: Contracts are evaluated at inception to determine whether they contain a lease. Operating lease right-of use assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the lease commencement date for operating leases with an initial term greater than 12 months. The Company recognizes lease expense for minimum lease payments on a straight line basis over the term of the lease. Certain leases provide the option to purchase the leased property and are therefore evaluated for finance lease consideration. The depreciable life of leased assets are limited by the expected term of the lease, unless there is a transfer of title or purchase option and the Company believes it is reasonably certain of exercise. The Company utilizes its incremental borrowing rate by lease term to calculate the present value of our future lease payments if an implicit rate is not specified. See Note 19. Aerospace Aftermarket Programs: The Company participates in aftermarket RSPs under which the Company receives an exclusive right to manufacture and supply designated aftermarket parts over the life of the related aircraft engine program. As consideration, the Company has paid participation fees, which are recorded as long-lived intangible assets. The Company records amortization of the related intangible asset as sales dollars are being earned based on a proportional sales dollar method. Specifically, this method amortizes each asset as a reduction to revenue based on the proportion of sales under a program in a given period to the estimated aggregate sales dollars over the life of that program. This method reflects the pattern in which the economic benefits of the RSPs are realized. The Company also entered into Component Repair Programs ("CRPs") that provide for, among other items, the right to sell certain aftermarket component repair services for CFM56, CF6, CF34 and LM engines directly to other customers as one of a few GE licensed suppliers. In addition, the CRPs extended certain existing contracts under which the Company currently provides these services directly to GE. The Company recorded the consideration paid for these rights as an intangible asset that is amortized as a reduction to sales over the remaining life of these engine programs based on the estimated sales over the life of such programs. This method reflects the pattern in which the economic benefits of the CRPs are realized. The recoverability of each asset is subject to significant estimates about future revenues related to the program’s aftermarket parts and services. The Company evaluates these intangible assets for recoverability and updates amortization rates on an agreement by agreement basis for the RSPs and on an individual asset program basis for the CRPs. The assets are reviewed for recoverability periodically including whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. At least annually, the Company evaluates the remaining useful life of these assets to determine whether events and circumstances warrant a revision to the remaining periods of amortization. Management updates revenue projections, which includes comparing actual experience against projected revenue and industry projections. The potential exists that actual revenues will not meet expectations due to a change in market conditions including, for example, the replacement of older engines with new, more fuel-efficient engines or the Company's ability to maintain market share within the Aerospace Aftermarket Products and Services ("Aftermarket") business, which includes maintenance repair and overhaul (“MRO”) services and the manufacture and delivery of aerospace aftermarket spare parts. A shortfall in future revenues may indicate a triggering event requiring a write down or further evaluation of the recoverability of the assets or require the Company to accelerate amortization expense prospectively dependent on the level of the shortfall. The Company has not identified any impairment of these assets, although changes in projected RSP and CRP revenue has impacted amortization rates that will be applied in remaining periods. Other Intangible Assets: Other intangible assets consist primarily of the Aerospace Aftermarket programs, as discussed above, customer relationships, tradenames, patents and proprietary technology. These intangible assets, with the exception of certain tradenames, have finite lives and are amortized over the periods in which they provide benefit. The Company assesses the impairment of long-lived assets, including identifiable intangible assets subject to amortization, whenever significant events or significant changes in circumstances indicate the carrying value may not be recoverable. Tradenames with indefinite lives are subject to impairment testing in accordance with accounting standards governing such on an annual basis, in the second quarter, or more frequently if an event or change in circumstances indicates that the fair value of the asset has been reduced below its carrying value. Based on the assessments performed during 2023, there were no impairments of other intangible assets. See Note 6. Derivatives: Accounting standards related to the accounting for derivative instruments and hedging activities require that all derivative instruments be recorded on the balance sheet at fair value. Foreign currency contracts may qualify as fair value hedges of unrecognized firm commitments, cash flow hedges of recognized assets and liabilities or anticipated transactions, or a hedge of a net investment. Changes in the fair market value of derivatives that qualify as fair value hedges or cash flow hedges are recorded directly to earnings or accumulated other non-owner changes to equity, depending on the designation. Amounts recorded to accumulated other non-owner changes to equity are reclassified to earnings in a manner that matches the earnings impact of the hedged transaction. Any ineffective portion, or amounts related to contracts that are not designated as hedges, are recorded directly to earnings. The Company’s policy for classifying cash flows from derivatives is to report the cash flows consistent with the underlying hedged item. See Note 10. Foreign currency: Assets and liabilities are translated at year-end rates of exchange; revenues and expenses are translated at average rates of exchange. The resulting translation gains or losses are reflected in accumulated other non-owner changes to equity within stockholders’ equity. Net foreign currency transaction losses of $5,321, $540 and $572 in 2023, 2022 and 2021, respectively, were recorded within other expense (income), net in the Consolidated Statements of Income. Research and Development: Costs are incurred in connection with efforts aimed at discovering and implementing new knowledge that is critical to developing new products, processes or services, significantly improving existing products or services, and developing new applications for existing products and services. Research and development expenses for the creation of new and improved products, processes and services were $13,920, $15,774 and $22,928, for the years 2023, 2022 and 2021, respectively, and are included in selling and administrative expense. Pension and Other Postretirement Benefits: The Company accounts for its defined benefit pension plans and other postretirement plans by recognizing the overfunded or underfunded status of the plans, calculated as the difference between plan assets and the projected benefit obligation related to each plan, as an asset or liability on the Consolidated Balance Sheets. Benefit costs associated with the plans primarily include current service costs, interest costs and the amortization of actuarial losses, partially offset by expected returns on plan assets, which are determined based upon actuarial valuations. Settlement and curtailment losses (gains) may also impact benefit costs. The Company regularly reviews actuarial assumptions, including discount rates and the expected return on plan assets, which are updated at the measurement date, December 31st. The impact of differences between actual results and the assumptions are generally accumulated within Other Comprehensive Income and amortized over future periods, which will affect benefit costs recognized in such periods. The Company bifurcates the components of net periodic benefit cost for pension and other postretirement plans. The service cost component of expense requires presentation within other employee compensation costs in operating income, whereas the other components of expense are reported separately outside of operating income. See Note 12. Stock-Based Compensation: Stock-based employee compensation awards are accounted for based on their fair value on the grant date and the related cost is recognized in the Consolidated Statements of Income in accordance with accounting standards related to share-based payments. The fair values of stock options are estimated using the Black-Scholes option-pricing model based on certain assumptions. The fair values of service and performance based share awards are estimated based on the fair market value of the Company’s stock price on the grant date. The fair values of market based performance share awards and performance-vested stock options are estimated using the Monte Carlo valuation method. See Note 13. Income Taxes: Deferred tax assets and liabilities are recognized for future tax effects attributable to temporary differences, operating loss carryforwards and tax credits. The measurement of deferred tax assets and liabilities is determined using tax rates from enacted tax law of the period in which the temporary differences, operating loss carryforwards and tax credits are expected to be realized. The effect of a change in income tax rates is recognized in the period of the enactment date. The guidance related to accounting for income taxes requires that deferred tax assets be reduced by a valuation allowance if, based on all available evidence, it is more likely than not that the deferred tax asset will not be realized. The Company is exposed to certain tax contingencies in the ordinary course of business and records those tax liabilities in accordance with the guidance for accounting for uncertain tax positions. The Company has elected to account for tax on Global Intangible Low- Taxed Income (“GILTI”) as a period cost, when incurred. See Note 14. Recent Accounting Standards The Financial Accounting Standards Board ("FASB") establishes changes to accounting principles under U.S. GAAP through the use of Accounting Standards Updates ("ASUs") to the FASB's Accounting Standards Codification. The Company evaluates the applicability and potential impacts of recent ASUs on its Consolidated Financial Statements and related disclosures. Recently Adopted Accounting Standards In December 2019, the FASB amended its guidance related to income taxes. The amended guidance simplifies the accounting for income taxes, eliminating certain exceptions to the general income tax principles, in an effort to reduce the cost and complexity of application. The amended guidance was effective for annual periods beginning after December 15, 2020, and interim periods within those reporting periods. The guidance requires application on either a prospective, retrospective or modified retrospective basis, contingent on the income tax exception being applied. The Company has adopted this guidance, on a prospective basis, on January 1, 2021 and it did not have a material impact on the Company's Consolidated Financial Statements. In October 2021, the FASB amended its guidance related to business combinations. The amended guidance requires entities to recognize and measure contract assets and contract liabilities acquired in business combinations on the acquisition date in accordance with Accounting Standards Codification 606, Revenue from Contracts with Customers. The new guidance was effective on a prospective basis for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company adopted this guidance, on a prospective basis, on January 1, 2023 and applied the guidance as it relates to the acquisition of MB Aerospace Holdings, Inc. See Note 2. In September 2022, the FASB amended its guidance related to supplier finance programs. The amended guidance requires additional disclosures surrounding the use of supplier finance programs to purchase goods or services including disclosing the key terms of the programs, the amount of obligations outstanding at the end of the reporting period, and a roll-forward of those obligations. The new guidance, except the amendment on roll-forward information, was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The amendment on roll-forward information is effective for fiscal years beginning after December 15, 2023. The Company adopted this guidance within the Consolidated Financial Statements filed as of March 31, 2023 and it did not have a material impact on the Company's Consolidated Financial Statements, however it did result in additional disclosures pursuant to the new guidance. See Note 22. Recently Issued Accounting Standards The United Kingdom's Financial Conduct Authority, which regulates the London Interbank Offered Rate (“LIBOR”), announced its intent to phase out the use of LIBOR by December 31, 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, identified the Secured Overnight Financing Rate (“SOFR”) as its preferred benchmark alternative to U.S. dollar LIBOR. Published by the Federal Reserve Bank of New York, SOFR represents a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is calculated based on directly observable U.S. Treasury-backed repurchase transactions. In March 2020, in response to this transition, the FASB issued guidance related to this rate reform, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued by reference rate reform, and addresses operational issues likely to arise in modifying contracts to replace discontinued reference rates with new rates. In January 2021, the FASB issued further clarifying guidance regarding derivatives, as it relates to this transition. In December 2022, the FASB extended the expiration of the guidance through December 31, 2024. The Company’s Unsecured Credit Agreement (see Note 8) and corresponding USD interest rate Swaps (see Note 10) each mature in February 2026. In March 2021, the Intercontinental Exchange Benchmark Association announced that it will extend the publication of overnight, 1, 3, 6 and 12 month LIBOR rates until June 30, 2023, while ceasing publication of all other LIBOR rates including 1 week and 2 month rates. The Company's Unsecured Credit Agreement was further amended in October 2021 and in April 2022 to address the replacement of LIBOR via the LIBOR Transition Agreement and Amendment No. 1, respectively (see Note 8), with SOFR. The Company's corresponding interest rate Swaps were amended in May 2022 to address the replacement of LIBOR. In June 2023, the Company entered into Amendment No. 2 ("Amendment No. 2") to the Unsecured Credit Agreement, which also addressed the option for the Company to borrow under the terms of SOFR (see Note 8). As a result of the Company's contract amendments to address the replacement of LIBOR, the Company does not anticipate a material impact on our business, financial condition, results of operations or cash flow as a result of this change. In November 2023, the FASB amended its guidance related to segment reporting requirements. The amended guidance serves to improve segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amended guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The guidance requires application on a retrospective basis to all periods presented. The Company is currently evaluating the impact that the guidance may have on the disclosures within its Consolidated Financial Statements. In December 2023, the FASB amended its guidance related to income tax disclosure requirements. The amended guidance requires establishes new income tax disclosure requirements including providing greater disaggregation in the rate reconciliation and information on taxes paid. The amended guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact that the guidance may have on the disclosures within its Consolidated Financial Statements.

Revenue recognition: The Company accounts for revenue in accordance with Accounting Standard Codification 606, Revenue from Contracts with Customers. Revenue is recognized by the Company when control of the product or solution is transferred to the customer. Control is generally transferred when products are shipped or delivered to customers, title is transferred, the significant risks and rewards of ownership have transferred, the Company has rights to payment and rewards of ownership pass to the customer. Customer acceptance may also be a factor in determining whether control of the product or solution has transferred. Although revenue is generally transferred at a point in time, a certain portion of businesses with customized products or contracts in which the Company performs work on customer-owned assets requires the use of an over time recognition model as certain contracts meet one or more of the established criteria pursuant to the accounting standards governing revenue recognition. Also, service revenue is recognized as control transfers, which is concurrent with the services being performed. See Note 3. Management fees related to the Aerospace Aftermarket Revenue Sharing Programs ("RSPs") are satisfied through an agreed upon reduction from the sales price of each of the related spare parts. These fees recognize our customer's necessary performance of engine program support activities, such as spare parts administration, warehousing and inventory management, and customer support, and are not separable from our sale of products, and accordingly, they are reflected as a reduction to sales, rather than as costs incurred, when revenues are recognized.

Inventories: Inventories are valued at the lower of cost, determined on a first-in, first-out basis, or net realizable value. The primary components of cost included in inventories are raw material, labor and overhead. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable value. The process for evaluating the value of excess and obsolete inventory often requires the Company to make judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be sold in the normal course of business and estimated costs. Accelerating the disposal process or changes in estimates based on future sales potential or estimated costs may necessitate future adjustments to these provisions.

Business Combinations: In accordance with the Business Combinations guidance, acquisitions are recorded using the acquisition method of accounting. The Company includes the operating results of acquired entities from their respective dates of acquisition. The Company allocates the purchase consideration to the assets acquired and liabilities assumed in the acquired entity generally based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired and liabilities assumed in the acquired entity is recorded as goodwill. The primary items that generate goodwill include the increase in global market access and the acquired assembled workforce, neither of which qualify for recognition as an intangible asset. Costs incurred as a result of a business combination other than costs related to the

Goodwill: Goodwill represents the excess purchase price over the fair value of net assets of companies acquired in business combinations. Goodwill is considered an indefinite-lived asset. Goodwill is subject to impairment testing in accordance with accounting standards governing such on an annual basis, in the second quarter, or more frequently if an event or change in circumstances indicates that the fair value of a reporting unit has been reduced below its carrying value. The Company utilizes the option to first assess qualitative factors to determine whether it is necessary to perform the Step 1 quantitative goodwill impairment test in accordance with the applicable accounting standards. Under the qualitative assessment, management considers relevant events and circumstances including but not limited to macroeconomic conditions, industry and market considerations, overall reporting unit performance and events directly affecting a reporting unit. If the Company determines that the Step 1 quantitative impairment test is required, management estimates the fair value of the reporting unit using the income approach. Inherent in management’s development of cash flow projections are assumptions and estimates, including those related to forecasted revenue growth rates, forecasted operating margins, and the weighted average cost of capital. The Company compares the fair value of the reporting unit with the carrying value of the reporting unit. If the fair values were to fall below the carrying values, the Company would recognize a non-cash impairment charge to income from operations for the amount by which the carrying amount of any reporting unit exceeds the reporting unit’s fair value, assuming the loss recognized does not exceed the total amount of goodwill for the reporting unit. Based on our assessment as of April 1, 2023, the estimated fair value of the Automation reporting unit, which represents the 2018 acquisition of Gimatic, exceeded its carrying value, while the estimated fair value of each of the remaining reporting units significantly exceeded their carrying values. See disclosure related to Other Intangible Assets below and within Note 6.

The Company also performed an annual assessment as of April 1, 2022, during the prior year period. The Company evaluated deteriorating macro-economic conditions subsequent to the date of the assessment, including inflationary pressures, rising interest rates, worsening global supply chain constraints and demand outlook, which materialized during the second quarter of 2022, impacting performance and outlook at Automation and resulted in a triggering event. Management revised its cash flow projections and weighted average cost of capital, resulting in a non-cash goodwill impairment charge of $68,194 related to the Automation reporting unit as the estimated fair value of the reporting unit declined below its carrying value. Management evaluated the significant increase in interest rates and further deteriorating macro-economic conditions that materialized during the fourth quarter of 2022, again resulting in a triggering event at Automation. Management performed a Step 1 quantitative assessment as of December 31, 2022 and concluded that there was no additional goodwill impairment at the business. The goodwill impairment charge was recorded in the three month period ended June 30, 2022.

Leases: Contracts are evaluated at inception to determine whether they contain a lease. Operating lease right-of use assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the lease commencement date for operating leases with an initial term greater than 12 months. The Company recognizes lease expense for minimum lease payments on a straight line basis over the term of the lease. Certain leases provide the option to purchase the leased property and are therefore evaluated for finance lease consideration. The depreciable life of leased assets are limited by the expected term of the lease, unless there is a transfer of title or purchase option and the Company believes it is reasonably certain of exercise. The Company utilizes its incremental borrowing rate by lease term to calculate the present value of our future lease payments if an implicit rate is not specified. See Note 19.

Aerospace Aftermarket Programs: The Company participates in aftermarket RSPs under which the Company receives an exclusive right to manufacture and supply designated aftermarket parts over the life of the related aircraft engine program. As consideration, the Company has paid participation fees, which are recorded as long-lived intangible assets. The Company records amortization of the related intangible asset as sales dollars are being earned based on a proportional sales dollar method. Specifically, this method amortizes each asset as a reduction to revenue based on the proportion of sales under a program in a given period to the estimated aggregate sales dollars over the life of that program. This method reflects the pattern in which the economic benefits of the RSPs are realized.

The Company also entered into Component Repair Programs ("CRPs") that provide for, among other items, the right to sell certain aftermarket component repair services for CFM56, CF6, CF34 and LM engines directly to other customers as one of a few GE licensed suppliers. In addition, the CRPs extended certain existing contracts under which the Company currently provides these services directly to GE. The Company recorded the consideration paid for these rights as an intangible asset that is amortized as a reduction to sales over the remaining life of these engine programs based on the estimated sales over the life of such programs. This method reflects the pattern in which the economic benefits of the CRPs are realized.

The recoverability of each asset is subject to significant estimates about future revenues related to the program’s aftermarket parts and services. The Company evaluates these intangible assets for recoverability and updates amortization rates on an agreement by agreement basis for the RSPs and on an individual asset program basis for the CRPs. The assets are reviewed for recoverability periodically including whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. At least annually, the Company evaluates the remaining useful life of these assets to determine whether events and circumstances warrant a revision to the remaining periods of amortization. Management updates revenue projections, which includes comparing actual experience against projected revenue and industry projections. The potential exists that actual revenues will not meet expectations due to a change in market conditions including, for example, the replacement of older engines with new, more fuel-efficient engines or the Company's ability to maintain market share within the Aerospace Aftermarket Products and Services ("Aftermarket") business, which includes maintenance repair and overhaul (“MRO”) services and the manufacture and delivery of aerospace aftermarket spare parts. A shortfall in future revenues may indicate a triggering event requiring a write down or further evaluation of the recoverability of the assets or require the Company to accelerate amortization expense prospectively dependent on the level of the shortfall. The Company has not identified any impairment of these assets, although changes in projected RSP and CRP revenue has impacted amortization rates that will be applied in remaining periods.

Other Intangible Assets: Other intangible assets consist primarily of the Aerospace Aftermarket programs, as discussed above, customer relationships, tradenames, patents and proprietary technology. These intangible assets, with the exception of certain tradenames, have finite lives and are amortized over the periods in which they provide benefit. The Company assesses the impairment of long-lived assets, including identifiable intangible assets subject to amortization, whenever significant events or significant changes in circumstances indicate the carrying value may not be recoverable. Tradenames with indefinite lives are subject to impairment testing in accordance with accounting standards governing such on an annual basis, in the second quarter, or more frequently if an event or change in circumstances indicates that the fair value of the asset has been reduced below its carrying value. Based on the assessments performed during 2023, there were no impairments of other intangible assets. See Note 6.

Derivatives: Accounting standards related to the accounting for derivative instruments and hedging activities require that all derivative instruments be recorded on the balance sheet at fair value. Foreign currency contracts may qualify as fair value hedges of unrecognized firm commitments, cash flow hedges of recognized assets and liabilities or anticipated transactions, or a hedge of a net investment. Changes in the fair market value of derivatives that qualify as fair value hedges or cash flow hedges are recorded directly to earnings or accumulated other non-owner changes to equity, depending on the designation. Amounts recorded to accumulated other non-owner changes to equity are reclassified to earnings in a manner that matches the earnings impact of the hedged transaction. Any ineffective portion, or amounts related to contracts that are not designated as hedges, are recorded directly to earnings. The Company’s policy for classifying cash flows from derivatives is to report the cash flows consistent with the underlying hedged item. See Note 10.

Research and Development: Costs are incurred in connection with efforts aimed at discovering and implementing new knowledge that is critical to developing new products, processes or services, significantly improving existing products or services, and developing new applications for existing products and services. Research and development expenses for the creation of new and improved products, processes and services were $13,920, $15,774 and $22,928, for the years 2023, 2022 and 2021, respectively, and are included in selling and administrative expense.

Pension and Other Postretirement Benefits: The Company accounts for its defined benefit pension plans and other postretirement plans by recognizing the overfunded or underfunded status of the plans, calculated as the difference between plan assets and the projected benefit obligation related to each plan, as an asset or liability on the Consolidated Balance Sheets. Benefit costs associated with the plans primarily include current service costs, interest costs and the amortization of actuarial losses, partially offset by expected returns on plan assets, which are determined based upon actuarial valuations. Settlement and curtailment losses (gains) may also impact benefit costs. The Company regularly reviews actuarial assumptions, including discount rates and the expected return on plan assets, which are updated at the measurement date, December 31st. The impact of differences between actual results and the assumptions are generally accumulated within Other Comprehensive Income and amortized over future periods, which will affect benefit costs recognized in such periods. The Company bifurcates the

Stock-Based Compensation: Stock-based employee compensation awards are accounted for based on their fair value on the grant date and the related cost is recognized in the Consolidated Statements of Income in accordance with accounting standards related to share-based payments. The fair values of stock options are estimated using the Black-Scholes option-pricing model based on certain assumptions. The fair values of service and performance based share awards are estimated based on the fair market value of the Company’s stock price on the grant date. The fair values of market based performance share awards and performance-vested stock options are estimated using the Monte Carlo valuation method. See Note 13.

Income Taxes: Deferred tax assets and liabilities are recognized for future tax effects attributable to temporary differences, operating loss carryforwards and tax credits. The measurement of deferred tax assets and liabilities is determined using tax rates from enacted tax law of the period in which the temporary differences, operating loss carryforwards and tax credits are expected to be realized. The effect of a change in income tax rates is recognized in the period of the enactment date. The guidance related to accounting for income taxes requires that deferred tax assets be reduced by a valuation allowance if, based on all available evidence, it is more likely than not that the deferred tax asset will not be realized. The Company is exposed to certain tax contingencies in the ordinary course of business and records those tax liabilities in accordance with the guidance for accounting for uncertain tax positions. The Company has elected to account for tax on Global Intangible Low- Taxed Income (“GILTI”) as a period cost, when incurred. See Note 14.

In December 2019, the FASB amended its guidance related to income taxes.

The United Kingdom's Financial Conduct Authority, which regulates the London Interbank Offered Rate (“LIBOR”), announced its intent to phase out the use of LIBOR by December 31, 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, identified the Secured Overnight Financing Rate (“SOFR”) as its preferred benchmark alternative to U.S. dollar LIBOR. Published by the Federal Reserve Bank of New York, SOFR represents a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is calculated based on directly observable U.S. Treasury-backed repurchase transactions. In March 2020, in response to this transition, the FASB issued guidance related to this rate reform, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued by reference rate reform, and addresses operational issues likely to arise in modifying contracts to replace discontinued reference rates with new rates. In January 2021, the FASB issued further clarifying guidance regarding derivatives, as it relates to this transition. In December 2022, the FASB extended the expiration of the guidance through December 31, 2024. The Company’s Unsecured Credit Agreement (see Note 8) and corresponding USD interest rate Swaps (see Note 10) each mature in February 2026. In March 2021, the Intercontinental Exchange Benchmark Association announced that it will extend the publication of overnight, 1, 3, 6 and 12 month LIBOR rates until June 30, 2023, while ceasing publication of all other LIBOR rates including 1 week and 2 month rates. The Company's Unsecured Credit Agreement was further amended in October 2021 and in April 2022 to address the replacement of LIBOR via the LIBOR Transition Agreement and Amendment No. 1, respectively (see Note 8), with SOFR. The Company's corresponding interest rate Swaps were amended in May 2022 to address the replacement of LIBOR. In June 2023, the Company entered into Amendment No. 2 ("Amendment No. 2") to the Unsecured Credit Agreement, which also addressed the option for the Company to borrow under the terms of SOFR (see Note 8). As a result of the Company's contract amendments to address the replacement of LIBOR, the Company does not anticipate a material impact on our business, financial condition, results of operations or cash flow as a result of this change.
