Accounting Policies [Abstract]
Basis of Presentation	BASIS OF 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 5, Revenue and Segment Information , for 2022 financial results by segment and a recast of financial results by segment for the three-month fiscal period ended April 2, 2021. In the opinion of management, the condensed consolidated financial information reflects all adjustments necessary for a fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented, but do not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The Company has a calendar year-end; however, its first three fiscal quarters follow a 13-week convention, with each quarter ending on a Friday. The first quarters for 2022 and 2021 ended on April 1, 2022, and April 2, 2021, respectively.

Recent Accounting Standards [Abstract]
Recent Accounting Standards	RECENT ACCOUNTING STANDARDS Recent Accounting Standards Adopted In May 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("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 was permitted, including adoption in an interim period. The Company adopted this standard on January 1, 2022. The adoption of this standard update did not have a material impact on the Company's 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. Entities that previously required separate accounting for conversion features will report less interest expense as those conversion features were recorded as debt discounts which were amortized over the term of the debt. In addition, this ASU 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 requires the application of the if-converted method when calculating diluted 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 was 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. On January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective basis which resulted in a cumulative effect adjustment to the opening balance sheet. The prior period condensed consolidated financial statements have not been retroactively adjusted and continue to be reported under the accounting standard in effect for the period. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Adopted - continued The cumulative effect of the adjustments recorded to the opening balance sheet on January 1, 2022 for the adoption of ASU 2020-06 was as follows: in thousands Balance at December 31, 2021 Adjustments due to ASU 2020-06 Balance at January 1, 2022 Assets Deferred income taxes $ 15,717 $ 1,770 $ 17,487 Liabilities Long-term debt, excluding current portion, net of debt issuance costs $ 189,421 $ 7,624 $ 197,045 Equity Additional paid-in capital $ 248,153 $ (12,489) $ 235,664 Retained earnings 750,445 6,635 757,080 Beginning in 2022, the Company will calculate diluted EPS using the if-converted method for its convertible debt instruments, which is not expected to have a material impact on the consolidated results. Historically, the Company used the treasury stock method to calculate diluted EPS for its convertible debt instruments. In the first quarter of 2022, there was no impact as diluted EPS calculated to $0.14 using both the if-converted method and treasury stock method. Refer to Note 13, Debt, for further information on the Company's convertible notes. Recent Accounting Standards Yet to be Adopted In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method". The amendments in this standard update expand the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. This standard update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of this update for any entity that has adopted the amendments in ASU 2017-12 for the corresponding period. If an entity adopts the amendments in an interim period, the effect of adopting the amendments related to basis adjustments should be reflected as of the beginning of the fiscal year of adoption. 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 hedging activity. 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. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) 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.

Discontinued Operations [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	. DISPOSALS UK Composites Business In the fourth quarter of 2020, the Company received approval from its Board of Directors to sell its United Kingdom ("UK") Composites division. The sale of the UK Composites business did not meet the criteria set forth in ASC 205-20 for discontinued operations as it did not reflect a significant shift in the Company's strategy. As a result of the approved plan, the UK Composites division met the criteria set forth in ASC 205-20 for held for sale presentation at December 31, 2020. 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 such, the assets of the UK Composites business were written off and the related liabilities of the UK division to be sold were reclassified to liabilities held for sale, as of December 31, 2020 on the Company's Consolidated Balance Sheets. The Company recorded an impairment loss of $36.3 million in the year ended December 31, 2020. The Company sold its UK Composites division in a transaction that closed on February 2, 2021. In the three-month fiscal period ended April 2, 2021, when the sale was finalized, the Company recorded an additional loss of $0.2 million, resulting in a total loss on the sale of the UK Composites business of $36.5 million. Cash and cash equivalents and restricted cash at the beginning of the period on the Company's Condensed Consolidated Statement of Cash Flows for the three-month fiscal period ended April 2, 2021 included $6.6 million of cash that was included in the UK Composites business disposal group. Given the assets of the disposal group were recognized net of the impairment recorded in the year ended December 31, 2020, such amounts were not reflected on the Company's Condensed Consolidated Balance Sheet at December 31, 2020. 3. DISPOSALS (CONTINUED) Distribution Business On August 26, 2019, the Company completed the sale of its Distribution business. Upon closing, the Company entered into a transition services agreement ("TSA") with the buyer, pursuant to which the Company agreed to support the information technology ("IT"), human resources and benefits, tax and treasury functions of the Distribution business for six to twelve months. The buyer exercised an option to extend the support period for up to one additional year for certain services. During the third quarter of 2021, the TSA expired and all services were completed as of the end of the period. As such, there was no activity associated with the TSA in 2022. Through the term of the TSA, the Company incurred $18.9 million in costs and earned $13.0 million in income associated with the TSA. Of these amounts, $0.7 million in costs were incurred and $0.5 million in income was earned in three-month fiscal period ended April 2, 2021. These amounts were included in costs from transition services agreement and income from transition services agreement on the Company's Condensed Consolidated Statements of Operations, respectively. Since the sale of the Distribution business, cash outflows from the Company to its former Distribution business totaled $8.7 million through April 1, 2022, which primarily related to Distribution employee and employee-related costs incurred prior to the sale. There were no cash flows from the Company to its former Distribution business in the three-month fiscal periods ended April 1, 2022 and April 2, 2021. Since the sale of the Distribution business, cash inflows from the Company's former Distribution business to the Company totaled $18.9 million through April 1, 2022, which primarily related to cash received for services performed under the TSA and the $5.2 million working capital adjustment settled in the first quarter of 2020. Cash inflows from the Company's former Distribution business received in the three-month fiscal period ended April 2, 2021 totaled $0.5 million. Cash inflows from the former Distribution business were not material in 2022.

REVENUE AND SEGMENT INFORMATION (CONTINUED) Disaggregation of Revenue - continued COVID-19 The impact of the novel coronavirus (“COVID-19”) and the precautionary measures instituted by governments and businesses to mitigate the spread, including limiting non-essential travel, have contributed to a general slowdown in the global economy. The Company has implemented strategies to limit the risk to its operations with a continued focus on the health of its employees and the satisfaction of its customers’ requirements. Despite all of these efforts to mitigate the risks associated with COVID-19, the effects of the pandemic have adversely impacted our commercial end markets, more specifically Commercial, Business and General Aviation customers. Management is encouraged by the recoveries for these products and the strong order intake seen in the first three months of 2022. The extent and duration of time to which COVID-19 may adversely impact the Company depends on future developments, which continue to be uncertain and unpredictable. The following table disaggregates total revenue by product types. For the Three Months Ended April 1, 2022 Engineered Products Precision Products Structures Total Original Equipment Manufacturer 41 % 2 % 18 % 61 % Aftermarket 11 % 4 % — % 15 % Safe and Arm Devices — % 24 % — % 24 % Total revenue 52 % 30 % 18 % 100 % For the Three Months Ended April 2, 2021 Engineered Products Precision Products Structures Total Original Equipment Manufacturer 32 % 8 % 23 % 63 % Aftermarket 10 % 3 % — % 13 % Safe and Arm Devices — % 24 % — % 24 % Total revenue 42 % 35 % 23 % 100 % Disaggregation of Research and Development Costs The following table presents research and development costs by segment: For the Three Months Ended April 1, April 2, In thousands Engineered Products $ 2,243 $ 2,822 Precision Products 2,803 1,402 Structures 67 2 Total research and development costs $ 5,113 $ 4,226 5. REVENUE AND SEGMENT INFORMATION (CONTINUED) Other For contracts in which revenue is recognized 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. Net changes in revenue associated with cost growth on the Company's over time contracts were as follows: For the Three Months Ended April 1, April 2, In thousands Net change in revenue due to change in profit estimates $ 905 $ 2,865 In the three-month fiscal periods ended April 1, 2022 and April 2, 2021, the net increases in revenue were primarily related to favorable cost performance on the joint programmable fuze ("JPF") contract with the U.S. Government ("USG"), partially offset by cost growth on certain structures programs and legacy fuzing contracts. 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. Backlog at April 1, 2022 and December 31, 2021, and the portion of backlog the Company expects to recognize revenue on over the next twelve months is as follows: April 1, 2022 (1) December 31, In thousands Backlog $ 705,023 $ 700,923 (1) The Company expects to recognize revenue on approximately 62% of backlog as of April 1, 2022 over the next twelve months.

There were no significant impairment losses related to the Company's contract assets during the three-month fiscal periods ended April 1, 2022 and April 2, 2021. Contract assets includes amounts for matters such as contract changes, negotiated settlements and claims for unanticipated contract costs. These amounts were as follows: April 1, December 31, In thousands Contract changes, negotiated settlements and claims for unanticipated contract costs $ 695 $ 682 Contract Costs At April 1, 2022 and December 31, 2021, costs to fulfill a contract were $11.0 million and $11.1 million, respectively. These amounts were included in contract costs, current portion and contract costs, noncurrent portion on the Company's Condensed Consolidated Balance Sheets at April 1, 2022 and December 31, 2021. There were no costs to obtain a contract at April 1, 2022 and December 31, 2021. Contract costs, current portion at April 1, 2022 remained relatively flat compared to the balance at December 31, 2021. This was primarily attributable to the amortization of contract costs, mostly offset by the reclassification of a portion of costs to fulfill certain structures programs from contract costs, noncurrent portion. For the three-month fiscal periods ended April 1, 2022 and April 2, 2021, amortization of contract costs was $0.1 million and $1.9 million, respectively. The decrease in contract costs, noncurrent portion was attributable to the reclassification of costs on certain structures programs to contract costs, current portion. Contract Liabilities The decrease in contract liabilities, current portion was primarily due to revenue recognized on our seals, springs and contacts, partially offset by advances received for the SH-2G program for New Zealand. Revenue recognized related to contract liabilities, current portion was $0.5 million and $9.4 million in the three-month fiscal periods ended April 1, 2022 and April 2, 2021, respectively. 8. CONTRACT ASSETS, CONTRACT COSTS AND CONTRACT LIABILITIES (CONTINUED) Contract Liabilities - continued Contract liabilities, noncurrent portion at April 1, 2022 remained flat compared to the balance at December 31, 2021. For the three-month fiscal periods ended April 1, 2022 and April 2, 2021, the Company did not recognize revenue against contract liabilities, noncurrent portion.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The following table presents the carrying value and fair value of financial instruments that are not carried at fair value: April 1, 2022 December 31, 2021 Carrying Value Fair Value Carrying Value Fair Value In thousands Debt (1) $ 199,500 $ 203,470 $ 191,876 $ 213,222 (1) These amounts are classified within Level 2. The above fair values were computed based on quoted market prices and discounted future cash flows (observable inputs), as applicable. Differences from carrying values are attributable to interest rate changes subsequent to when the transactions occurred. The fair values of cash and cash equivalents, accounts receivable, net and accounts payable - trade approximate their carrying amounts due to the short-term maturities of these instruments. The Company's cash and cash equivalents at April 1, 2022 and December 31, 2021 included $65.5 million of Level 1 money market funds in both periods. Recurring Fair Value Measurements The Company holds derivative instruments for foreign exchange contracts that are measured at fair value using observable market inputs such as forward rates and its counterparties’ credit risks. Based on these inputs, the derivative instruments are classified within Level 2 of the valuation hierarchy. At April 1, 2022 and December 31, 2021, the derivative instruments were included in other current assets and other current liabilities on the Company's Condensed Consolidated Balance Sheets. Based on the Company's continued ability to trade and enter into forward contracts and interest rate swaps, the Company considers the markets for its fair value instruments to be active. The Company evaluated the credit risk associated with the counterparties to these derivative instruments and determined that as of April 1, 2022, such credit risks had not had an adverse impact on the fair value of these instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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 Condensed 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 (loss) are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not use derivative instruments for speculative purposes. Forward Exchange Contracts The Company holds forward exchange contracts designed to hedge forecasted transactions denominated in foreign currencies and to minimize the impact of foreign currency fluctuations on the Company’s earnings and cash flows. Some of these contracts are designated as cash flow hedges. The Company will include in earnings amounts currently included in accumulated other comprehensive income (loss) upon recognition of cost of sales related to the underlying transaction. These contracts were not material to the Company's Condensed Consolidated Balance Sheets as of April 1, 2022 and December 31, 2021. The activity related to these contracts was not material to the Company's Condensed Consolidated Financial Statements for the three-month fiscal periods ended April 1, 2022 and April 2, 2021.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Pension Freeze Effective December 31, 2015, the Company's qualified pension plan was frozen with respect to future benefit accruals. Under USG Cost Accounting Standard (“CAS”) 413, the Company must determine the USG’s share of any pension curtailment adjustment calculated in accordance with CAS. Such adjustments can result in an amount due to the USG for pension plans that are in a surplus position or an amount due to the contractor for plans that are in a deficit position. During the fourth quarter of 2016, the Company accrued a $0.3 million liability representing its estimate of the amount due to the USG based on the Company's pension curtailment adjustment calculation, which was submitted to the USG for review in December 2016. The Company maintained its accrual at $0.3 million as of April 1, 2022. There can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on the Company's results of operations, financial position and cash flows. 15. COMMITMENTS AND CONTINGENCIES (CONTINUED) New Hartford Property In connection with the sale of the Company’s Music segment in 2007, the Company assumed responsibility for meeting certain requirements of the Connecticut Transfer Act (the “Transfer Act”) that applied to the transfer of the New Hartford, Connecticut, facility leased by that segment for guitar manufacturing purposes (“Ovation”). Under the Transfer Act, those responsibilities essentially consist of assessing the site's environmental conditions and remediating environmental impairments, if any, caused by Ovation's operations prior to the sale. The site is a multi-tenant industrial park, in which Ovation and other unrelated entities lease space. The environmental assessment process, which began in 2008, has been completed and site remediation is in process. The Company's estimate of its portion of the cost to assess the environmental conditions and remediate this site is $2.3 million, all of which has been accrued. The remediation has been nearly completed and the Company continues to monitor the results of the remediation. The total amount paid to date in connection with these environmental remediation activities is $1.7 million. At April 1, 2022, the Company had $0.6 million accrued for these environmental remediation activities. A portion ($0.1 million) of the accrual related to this property is included in other current liabilities and the balance is included in other long-term liabilities. The remaining balance of the accrual reflects the total anticipated cost of completing these environmental remediation activities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Bloomfield Property In connection with the Company’s 2008 purchase of the portion of the Bloomfield campus that Kaman Aerospace Corporation had leased from NAVAIR, the Company assumed responsibility for environmental remediation at the facility as may be required under the Transfer Act and is currently remediating the property under the guidance of the Connecticut Department of Environmental Protection. The assumed environmental liability of $10.3 million was determined by taking the undiscounted estimated remediation liability of $20.8 million and discounting it at a rate of 8%. This remediation process will take many years to complete. The total amount paid to date in connection with these environmental remediation activities is $14.9 million. At April 1, 2022, the Company had $2.3 million accrued for these environmental remediation activities. A portion ($0.2 million) of the accrual related to this property is included in other current liabilities, and the balance is included in other long-term liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Offset Agreement During January 2018, the Company entered into an offset agreement as a condition to obtaining orders from a foreign customer for the Company's JPF product. This agreement is designed to return economic value to the foreign country by requiring the Company to engage in activities supporting local defense or commercial industries, promoting a balance of trade, developing in-country technology capabilities or addressing other local development priorities. The offset agreement may be satisfied through activities that do not require a direct cash payment, including transferring technology, providing manufacturing, training and other consulting support to in-country projects and the purchase by third parties of supplies from in-country vendors. This agreement may also be satisfied through the Company's use of cash for activities, such as subcontracting with local partners, purchasing supplies from in-country vendors, providing financial support for in-country projects and making investments in local ventures. At April 1, 2022, the offset agreement had an outstanding notional value of approximately $194.0 million, which is equal to sixty percent of the contract value of $324.0 million as defined by the agreement between the customer and the Company. The amount ultimately applied against the offset agreement is based on negotiations with the customer and may require cash outlays that represent only a fraction of the notional value in the offset agreement. 15. COMMITMENTS AND CONTINGENCIES (CONTINUED) Offset Agreement - continued The Company continues to work with the customer to further define the requirements to satisfy the offset agreement. The satisfaction of the offset requirements will be determined by the customer and is expected to occur over a seven-year period. Deliveries under the contract were completed prior to satisfaction of the offset requirements. In the event the offset requirements of the contract are not met, the Company could be liable for potential penalties up to $16.5 million payable to the customer. Failure to satisfy the offset requirement could also negatively impact the Company's ability to attract future orders from this customer. The Company began recognizing revenue associated with this contract in the third quarter of 2019 and has considered the potential penalties of $16.5 million as a reduction to the transaction price in its determination of the value of the performance obligations within this contract. At April 1, 2022, $16.5 million in contract liabilities associated with the potential penalties of the offset requirements were included on the Company's Condensed Consolidated Balance Sheets. Guarantee During 2020, the Company and the USG entered into a Guaranty Agreement, pursuant to which the Company agreed to guarantee the full, complete and satisfactory performance of its subsidiary, Kaman Precision Products, Inc. ("KPPI") under all current and future contracts with the USG. As of the date of this filing, the only contract in place between KPPI and the USG relates to the production and sale of the JPF. KPPI is currently fulfilling the requirements of Option 15 and Option 16. The guarantee was provided in lieu of a periodic financial capability review by the Financial Capacity Team ("FCT") of the Defense Contract Management Agency ("DCMA"). The Company is unable to estimate the maximum potential amount of future payments under the guarantee as it is dependent on costs incurred by the USG in the event of default. Although the Company believes the risk of default is low given the maturity and operational performance of the JPF program, there can be no assurance that the guarantee will not have a material adverse effect on the Company's results of operations, financial position and cash flows.

Earnings Per Share Reconciliation [Abstract]
Computation of Earnings Per Share	COMPUTATION OF EARNINGS PER SHARE The computation of basic earnings per share is based on net earnings divided by the weighted average number of shares of common stock outstanding for each period. The computation of diluted earnings per share reflects the common stock equivalency of dilutive options granted to employees under the Company's stock incentive plan, shares issuable on redemption of its convertible notes and shares issuable upon redemption of outstanding warrants. For the Three Months Ended April 1, April 2, In thousands, except per share amounts Net earnings $ 4,028 $ 7,984 Basic: Weighted average number of shares outstanding 27,950 27,815 Basic earnings per share $ 0.14 $ 0.29 Diluted (1) : Weighted average number of shares outstanding 27,950 27,815 Weighted average shares issuable on exercise of dilutive stock options 132 52 Total 28,082 27,867 Diluted earnings per share $ 0.14 $ 0.29 (1) As a result of the adoption of ASU 2020-06, the Company began calculating diluted earnings per share using the if-converted method for its convertible debt instruments in 2022. Prior to the adoption, the Company calculated diluted earnings per share for its convertible debt instruments using the treasury stock method. The Company adopted ASU 2020-06 using the modified retrospective approach; therefore, prior period results have not been retroactively adjusted. Refer to Note 2, Recent Accounting Standards , for further information on the adoption of ASU 2020-06. Equity awards For the three-month fiscal periods ended April 1, 2022 and April 2, 2021, respectively, 645,403 and 440,959 shares issuable under equity awards granted to employees were excluded from the calculation of diluted earnings per share as they were anti-dilutive based on the average stock price during the periods. 2024 Convertible Notes For the three-month fiscal period ended April 1, 2022, 3,056,879 shares issuable under Convertible Notes due 2024 were excluded from the diluted earnings per share calculation because their effect was antidilutive. For the three-month fiscal period ended April 2, 2021, shares issuable under the Convertible Notes due 2024 were excluded from the diluted earnings per share calculation because the conversion price was more than the average market price of the Company's stock during the periods.

Share-based Payment Arrangement, Noncash Expense [Abstract]
Share-based Payment Arrangement	17. SHARE-BASED ARRANGEMENTS The Company accounts for stock options, restricted stock awards ("RSAs"), restricted stock units and performance stock units ("PSUs") as equity awards and measures the cost of all share-based payments, including stock options, at fair value on the grant date and recognizes this cost in the statement of operations. The Company also has an employee stock purchase plan, which is accounted for as a liability award. Compensation expense for stock options, RSAs, restricted stock units and PSUs is recognized on a straight-line basis over the vesting period of the awards. Throughout the course of the vesting period, the Company monitors the achievement level for the ROIC metric of the PSUs compared to the ROIC target and adjusts the number of shares expected to be earned, and the related compensation expense recorded thereafter, to reflect the most probable outcome. Share-based compensation expense recorded for the three-month fiscal periods ended April 1, 2022 and April 2, 2021 was $2.1 million and $1.7 million, respectively. These amounts were recorded to selling, general and administrative expenses on the Company's Condensed Consolidated Statements of Operations. 17.

Debt Disclosure [Abstract]
Debt Disclosure	13. DEBT Convertible Notes During May 2017, the Company issued $200.0 million aggregate principal amount of convertible senior unsecured notes due May 2024 (the "2024 Notes") pursuant to an indenture (the "Indenture"), dated May 12, 2017, between the Company and U.S. Bank National Association, as trustee. In connection therewith, the Company entered into certain capped call transactions that cover, collectively, the number of shares of the Company's common stock underlying the 2024 Notes. On May 12, 2017, the Company issued $175.0 million in principal amount of 2024 Notes, in a private placement offering. On May 24, 2017, the Company issued an additional $25.0 million in principal amount of 2024 Notes pursuant to the initial purchasers' exercise of their overallotment option, resulting in the issuance of an aggregate $200.0 million principal amount of 2024 Notes. The 2024 Notes bear 3.25% interest per annum on the principal amount, payable semiannually in arrears on May 1 and November 1 of each year, beginning on November 1, 2017. The 2024 Notes will mature on May 1, 2024, unless earlier repurchased by the Company or converted. The Company will settle any conversions of the 2024 Notes in cash, shares of the Company's common stock or a combination of cash and shares of common stock, at the Company's election. 13. DEBT (CONTINUED) Convertible Notes - continued The sale of the Distribution business in the third quarter of 2019 was deemed to be a "Fundamental Change" and a "Make-Whole Fundamental Change" pursuant to the terms and conditions of the indenture governing the 2024 Notes. As a result, the sale triggered the right of the holders of our 2024 Notes to require us to repurchase all of the 2024 Notes, or any portion thereof that is a multiple of $1,000 principal amount on September 27, 2019. The aggregate principal amount of the 2024 Notes validly tendered and not validly withdrawn was $0.5 million, representing 0.25% of all outstanding notes. Holders of such notes receive the purchase price equal to 100% of the principal amount of the 2024 Notes being purchased, plus accrued and unpaid interest. The following table illustrates the conversion rate at the date of issuance of the 2024 Notes: 2024 Notes Conversion Rate per $1,000 principal amount (1) 15.3227 Conversion Price (2) 65.2626 Contingent Conversion Price (3) 84.8413 Aggregate shares to be issued upon conversion (4) 3,056,879 (1) Represents the number of shares of Common Stock hypothetically issuable per each $1,000 principal amount of 2024 Notes, subject to adjustments upon the occurrence of certain specified events in accordance with the terms of the Indenture. (2) Represents $1,000 divided by the conversion rate as of such date. The conversion price reflects the strike price of the embedded option within the 2024 Notes. If the Company's share price exceeds the conversion price at conversion, the noteholders would be entitled to receive additional consideration either in cash, shares or a combination thereof, the form of which is at the sole discretion of the Company. (3) Prior to November 1, 2023, the notes are convertible only in the following circumstances: (1) during any fiscal quarter commencing after July 1, 2017, and only during any such fiscal quarter, if the last reported sale price of the Company's common stock was greater than or equal to 130% of the applicable conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter, (2) during the five consecutive business day period following any ten consecutive trading day period (the "measurement period") in which the trading price per $1,000 principal amount of 2024 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day or (3) upon the occurrence of specified corporate events. On or after November 1, 2023, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. If the Company undergoes a fundamental change (as defined in the Indenture), holders of the notes may require the Company to repurchase all or a portion of their notes for cash at a repurchase price equal to 100% of the principal amount to be repurchased, plus any accrued and unpaid interest. As of April 1, 2022, none of the conditions permitting the holders of the 2024 Notes to convert had been met. Therefore, the 2024 Notes are classified as long-term debt. (4) This represents the number of shares hypothetically issuable upon conversion of 100% of the outstanding aggregate principal amount of the 2024 Notes at each date; however, the terms of the 2024 Notes state that the Company may pay or deliver, as the case may be, cash, shares of the Company's common stock or a combination of cash and shares of common stock, at the Company's election. The Company currently intends to settle the aggregate principal amount in cash. Amounts due in excess of the principal, if any, also may be settled in cash, shares of the Company's common stock or a combination of cash and shares of common stock, at the Company's election. In connection with the 2024 Notes offering, the Company entered into capped call transactions with certain of the initial purchasers or their respective affiliates. These transactions are intended to reduce the potential dilution to the Company's shareholders and/or offset the cash payments the Company is required to make in excess of the principal amount upon any future conversion of the notes in the event that the market price per share of the Company's common stock is greater than the strike price of the capped call transactions, with such reduction and/or offset subject to a cap based on the cap price of the capped call transactions. Under the terms of the capped call transactions, the strike price ($65.2626) and the cap price ($88.7570) are each subject to adjustment in certain circumstances. In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates entered into various derivative transactions with respect to the Company’s common stock concurrently with or shortly after the pricing of the notes. The capped call transactions, which cost an aggregate $20.5 million, were recorded as a reduction of additional paid-in capital. 13. DEBT (CONTINUED) Convertible Notes - continued ASC Topic 815 - Derivatives and Hedging ("ASC 815") provides that contracts are initially classified as equity if (1) the contract requires physical settlement or net-share settlement, or (2) the contract gives the company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The settlement terms of our capped call transactions require net-share settlement. Based on the guidance in ASC 815, the capped call transactions were recorded as a reduction of equity as of the trade date. ASC 815 states that a reporting entity shall not consider contracts to be derivative instruments if the contract issued or held by the reporting entity is both indexed to its own stock and classified in shareholders' equity in its balance sheet. The Company concluded the capped call transactions should be accounted for in shareholders' equity and are, therefore, not to be considered a derivative instrument. At issuance, ASC 470-20 "Debt with Conversion and Other Options " (“ASC 470-20”) clarified the accounting for convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement. ASC 470-20 specified that an issuer of such instruments should separately account for the liability and equity components of the instruments in a manner that reflects the issuer's non-convertible debt borrowing rate which interest costs are to be recognized in subsequent periods. The note payable principal balance for the 2024 Notes at the date of issuance of $200.0 million was bifurcated into the debt component of $179.5 million and the equity component of $20.5 million. The difference between the note payable principal balance and the fair value of the debt component representing the debt discount was being accreted to interest expense over the term of the 2024 Notes. The fair value of the debt component was recognized using a 5.0% discount rate, representing the Company's borrowing rate at the date of issuance for a similar debt instrument without a conversion feature with an expected life of seven years. At January 1, 2022, the Company adopted ASU 2020-06, which removed certain separation models between a debt component and equity component for certain convertible instruments. As a result, the convertible notes balance consists solely of a debt component as of the adoption. Refer to Note 2, Recent Accounting Standards , for further information on the cumulative effect adjustment recorded at adoption. The Company incurred $7.4 million of debt issuance costs in connection with the sale of the 2024 Notes, which was allocated between the debt and equity components of the instrument at issuance. Of the total amount, $0.7 million was recorded as an offset to additional paid-in capital. The balance, $6.7 million, was recorded as a contra-debt balance and was being amortized over the term of the 2024 Notes. As a result of the adoption of ASU 2020-06, the amount recorded to additional paid-in capital was reclassified to retained earnings in the cumulative effect adjustment. The remaining balance of debt issuance costs is being amortized over the term of the convertible notes. Total amortization expense for the three-month fiscal periods ended April 1, 2022 and April 2, 2021 was $0.2 million in both periods. The carrying amount of the equity component and the principal amount of the liability component, the unamortized discount and the net carrying value of the liability are as follows: 2024 Notes April 1, December 31, In thousands Principal amount of liability $ 199,500 $ 199,500 Unamortized discount (1) — 7,624 Carrying value of liability $ 199,500 $ 191,876 Equity component (1) $ — $ 20,408 (1) At January 1, 2022, the Company adopted ASU 2020-06, which removed certain separation models between a debt component and equity component for certain convertible instruments. Refer to Note 2, Recent Accounting Standards , for further information on the cumulative effect adjustment recorded at adoption. Because the embedded conversion option is indexed to the Company’s own stock and would be classified in shareholders’ equity, it does not meet the criterion under ASC 815 that would require separate accounting as a derivative instrument. 13. DEBT (CONTINUED) Convertible Notes - continued Interest expense associated with the 2024 Notes consisted of the following: For the Three Months Ended April 1, April 2, In thousands Contractual coupon rate of interest $ 1,621 $ 1,621 Accretion of convertible notes discount (1) — 737 Interest expense - convertible notes $ 1,621 $ 2,358 (1) In accordance with ASU 2020-06, entities that previously required separate accounting for conversion features will report less interest expense as those conversion features were recorded as debt discounts which were amortized over the term of the debt. Refer to Note 2, Recent Accounting Standards , for further information on the adoption of ASU 2020-06. The weighted average interest rate on long-term borrowings outstanding as of April 1, 2022 and December 31, 2021 was 3.25% in both periods.

Basis of Presentation [Abstract]
Consolidation, Policy [Policy Text Block]	BASIS OF 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 5, Revenue and Segment Information , for 2022 financial results by segment and a recast of financial results by segment for the three-month fiscal period ended April 2, 2021. In the opinion of management, the condensed consolidated financial information reflects all adjustments necessary for a fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented, but do not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). All such adjustments are of a normal recurring nature, unless otherwise disclosed in this report. Certain amounts in prior year financial statements and notes thereto have been reclassified to conform to current year presentation. The statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The Company has a calendar year-end; however, its first three fiscal quarters follow a 13-week convention, with each quarter ending on a Friday. The first quarters for 2022 and 2021 ended on April 1, 2022, and April 2, 2021, respectively.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	RECENT ACCOUNTING STANDARDS Recent Accounting Standards Adopted In May 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("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 was permitted, including adoption in an interim period. The Company adopted this standard on January 1, 2022. The adoption of this standard update did not have a material impact on the Company's 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. Entities that previously required separate accounting for conversion features will report less interest expense as those conversion features were recorded as debt discounts which were amortized over the term of the debt. In addition, this ASU 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 requires the application of the if-converted method when calculating diluted 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 was 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. On January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective basis which resulted in a cumulative effect adjustment to the opening balance sheet. The prior period condensed consolidated financial statements have not been retroactively adjusted and continue to be reported under the accounting standard in effect for the period. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Adopted - continued The cumulative effect of the adjustments recorded to the opening balance sheet on January 1, 2022 for the adoption of ASU 2020-06 was as follows: in thousands Balance at December 31, 2021 Adjustments due to ASU 2020-06 Balance at January 1, 2022 Assets Deferred income taxes $ 15,717 $ 1,770 $ 17,487 Liabilities Long-term debt, excluding current portion, net of debt issuance costs $ 189,421 $ 7,624 $ 197,045 Equity Additional paid-in capital $ 248,153 $ (12,489) $ 235,664 Retained earnings 750,445 6,635 757,080 Beginning in 2022, the Company will calculate diluted EPS using the if-converted method for its convertible debt instruments, which is not expected to have a material impact on the consolidated results. Historically, the Company used the treasury stock method to calculate diluted EPS for its convertible debt instruments. In the first quarter of 2022, there was no impact as diluted EPS calculated to $0.14 using both the if-converted method and treasury stock method. Refer to Note 13, Debt, for further information on the Company's convertible notes. Recent Accounting Standards Yet to be Adopted In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method". The amendments in this standard update expand the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. This standard update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of this update for any entity that has adopted the amendments in ASU 2017-12 for the corresponding period. If an entity adopts the amendments in an interim period, the effect of adopting the amendments related to basis adjustments should be reflected as of the beginning of the fiscal year of adoption. 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 hedging activity. 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. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) 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.
Recent Accounting Standards	RECENT ACCOUNTING STANDARDS Recent Accounting Standards Adopted In May 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("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)".

On January 1, 2022, the Company adopted ASU 2020-06 using the modified retrospective basis which resulted in a cumulative effect adjustment to the opening balance sheet. The prior period condensed consolidated financial statements have not been retroactively adjusted and continue to be reported under the accounting standard in effect for the period. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) Recent Accounting Standards Adopted - continued The cumulative effect of the adjustments recorded to the opening balance sheet on January 1, 2022 for the adoption of ASU 2020-06 was as follows: in thousands Balance at December 31, 2021 Adjustments due to ASU 2020-06 Balance at January 1, 2022 Assets Deferred income taxes $ 15,717 $ 1,770 $ 17,487 Liabilities Long-term debt, excluding current portion, net of debt issuance costs $ 189,421 $ 7,624 $ 197,045 Equity Additional paid-in capital $ 248,153 $ (12,489) $ 235,664 Retained earnings 750,445 6,635 757,080 Beginning in 2022, the Company will calculate diluted EPS using the if-converted method for its convertible debt instruments, which is not expected to have a material impact on the consolidated results. Historically, the Company used the treasury stock method to calculate diluted EPS for its convertible debt instruments. In the first quarter of 2022, there was no impact as diluted EPS calculated to $0.14 using both the if-converted method and treasury stock method. Refer to Note 13, Debt, for further information on the Company's convertible notes. Recent Accounting Standards Yet to be Adopted In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method". The amendments in this standard update expand the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. This standard update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of this update for any entity that has adopted the amendments in ASU 2017-12 for the corresponding period. If an entity adopts the amendments in an interim period, the effect of adopting the amendments related to basis adjustments should be reflected as of the beginning of the fiscal year of adoption. 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 hedging activity. 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. 2. RECENT ACCOUNTING STANDARDS (CONTINUED) 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.

REVENUE AND SEGMENT INFORMATION (CONTINUED) Disaggregation of Revenue - continued COVID-19 The impact of the novel coronavirus (“COVID-19”) and the precautionary measures instituted by governments and businesses to mitigate the spread, including limiting non-essential travel, have contributed to a general slowdown in the global economy. The Company has implemented strategies to limit the risk to its operations with a continued focus on the health of its employees and the satisfaction of its customers’ requirements. Despite all of these efforts to mitigate the risks associated with COVID-19, the effects of the pandemic have adversely impacted our commercial end markets, more specifically Commercial, Business and General Aviation customers. Management is encouraged by the recoveries for these products and the strong order intake seen in the first three months of 2022. The extent and duration of time to which COVID-19 may adversely impact the Company depends on future developments, which continue to be uncertain and unpredictable.

Schedule of Changes in Conversion Rate for Convertible Notes	The following table illustrates the conversion rate at the date of issuance of the 2024 Notes: 2024 Notes Conversion Rate per $1,000 principal amount (1) 15.3227 Conversion Price (2) 65.2626 Contingent Conversion Price (3) 84.8413 Aggregate shares to be issued upon conversion (4) 3,056,879 (1) Represents the number of shares of Common Stock hypothetically issuable per each $1,000 principal amount of 2024 Notes, subject to adjustments upon the occurrence of certain specified events in accordance with the terms of the Indenture. (2) Represents $1,000 divided by the conversion rate as of such date. The conversion price reflects the strike price of the embedded option within the 2024 Notes. If the Company's share price exceeds the conversion price at conversion, the noteholders would be entitled to receive additional consideration either in cash, shares or a combination thereof, the form of which is at the sole discretion of the Company. (3) Prior to November 1, 2023, the notes are convertible only in the following circumstances: (1) during any fiscal quarter commencing after July 1, 2017, and only during any such fiscal quarter, if the last reported sale price of the Company's common stock was greater than or equal to 130% of the applicable conversion price for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter, (2) during the five consecutive business day period following any ten consecutive trading day period (the "measurement period") in which the trading price per $1,000 principal amount of 2024 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day or (3) upon the occurrence of specified corporate events. On or after November 1, 2023, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. If the Company undergoes a fundamental change (as defined in the Indenture), holders of the notes may require the Company to repurchase all or a portion of their notes for cash at a repurchase price equal to 100% of the principal amount to be repurchased, plus any accrued and unpaid interest. As of April 1, 2022, none of the conditions permitting the holders of the 2024 Notes to convert had been met. Therefore, the 2024 Notes are classified as long-term debt. (4) This represents the number of shares hypothetically issuable upon conversion of 100% of the outstanding aggregate principal amount of the 2024 Notes at each date; however, the terms of the 2024 Notes state that the Company may pay or deliver, as the case may be, cash, shares of the Company's common stock or a combination of cash and shares of common stock, at the Company's election. The Company currently intends to settle the aggregate principal amount in cash. Amounts due in excess of the principal, if any, also may be settled in cash, shares of the Company's common stock or a combination of cash and shares of common stock, at the Company's election.

Refer to Note 2, Recent Accounting Standards , for further information on the adoption of ASU 2020-06. The weighted average interest rate on long-term borrowings outstanding as of April 1, 2022 and December 31, 2021 was 3.25% in both periods.
