Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Hubbell Incorporated (“Hubbell”, the “Company”, “registrant”, “we”, “our” or “us”, which references include its divisions and subsidiaries) have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by United States of America (“U.S.”) GAAP for audited financial statements. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2022. The balance sheet at December 31, 2021 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Hubbell Incorporated Annual Report on Form 10-K for the year ended December 31, 2021. Discontinued Operations On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business (the "C&I Lighting business") to GE Current, a Daintree Company, for total cash consideration of $350 million , subject to customary adjustments with respect to working capital. The disposal of the Commercial and Industrial Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The Commercial and Industrial Lighting businesses' results of operations and the related cash flows have been reclassified to income from discontinued operations in the Condensed Consolidated Statements of Income and cash flows from discontinued operations in the Condensed Consolidated Statement of Cash Flows, respectively, for all periods presented. For additional information regarding this transaction and its effect on our financial reporting, see Note 2 – Discontinued Operations, in the accompanying Condensed Consolidated Financial Statements, which note is incorporated herein by reference. Impact of the COVID-19 Pandemic During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of a novel strain of coronavirus (COVID-19). The pandemic has had, and may continue to have, a significant effect on global economic conditions. U.S. Federal, state, local, and foreign governments have reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. and global economies. The extent to which the coronavirus pandemic will continue to affect our business, operations, supply chains, and our financial results will depend on numerous evolving factors that we may not be able to accurately predict and which may cause the actual results to differ from the estimates and assumptions we are required to make in the preparation of financial statements according to GAAP. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are effective for all entities beginning on March 12, 2020 through December 31, 2022. The Company may elect to apply the amendments prospectively through December 31, 2022. The Company has not adopted this ASU as of March 31, 2022. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption. In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." ASU 2021-08 requires an acquirer to recognize and measure contract assets and contract liabilities, including deferred revenue, acquired in a business combination in accordance with Revenue from Contracts with Customers (Topic 606) as if the acquirer had originated the contracts at the date of the business combination. The provisions of ASU 2021-08 are effective for interim periods and fiscal years beginning after December 15, 2022, with early adoption permitted. If early adopted, the provisions of ASU 2021-08 apply retrospectively to all business combinations that occurred on or after the first day of the fiscal year in which the standard is adopted. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On February 1, 2022, the Company completed the sale of the Commercial and Industrial Lighting business to GE Current, a Daintree Company, for total cash consideration of $350 million, subject to customary adjustments with respect to working capital. The sale of this business represents a strategic shift that will have a major effect on our operations and financial results, and as a result, is reported as a discontinued operation in our Condensed Consolidated Financial Statements for all periods presented. The assets and liabilities of this business are also presented as held for sale in the Condensed Consolidated Balance Sheets, in the periods prior to the sale. The Commercial and Industrial Lighting business was previously included in the Electrical Solutions segment. Under the terms of the transaction, Hubbell and the buyer entered into a transition services agreement ("TSA"), pursuant to which the Company agreed to provide certain administrative and operational services for a period of 12 months or less. Furthermore, we entered into a short-term supply agreement whereby the Company will act as a supplier of finished goods and component parts to the Commercial and industrial Lighting business after the completion of the sale. Income from the TSA and supply agreement was $2.8 million for the quarter ended March 31, 2022 and was recorded in Other Income in the Condensed Consolidated Financial Statements. The following table presents the summarized components of income from discontinued operations, net of income taxes, for the Commercial and Industrial Lighting business: Three Months Ended March 31, (in millions) 2022 2021 Net sales $ 29.1 $ 122.2 Cost of goods sold 27.7 96.0 Gross profit 1.4 26.2 Selling & administrative expenses 10.7 19.9 Operating (loss) income (9.3) 6.3 Gain on disposal of business 88.5 — Other income (expense) 0.2 (0.6) Income from discontinued operations before income taxes 79.4 5.7 Provision for income taxes 1.7 1.3 Income from discontinued operations, net of taxes $ 77.7 $ 4.4 Income from discontinued operations, net of taxes for the quarter ended March 31, 2022 includes transaction and separation costs of $2.1 million and a pre-tax gain on the disposal of $88.5 million.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company recognizes revenue when performance obligations identified under the terms of contracts with its customers are satisfied, which generally occurs, for products, upon the transfer of control in accordance with the contractual terms and conditions of the sale. The majority of the Company’s revenue associated with products is recognized at a point in time when the product is shipped to the customer, with a relatively small amount of transactions primarily in the Utility Solutions segment recognized upon delivery of the product at the destination. Revenue from service contracts and post-shipment performance obligations are approximately two percent of total annual consolidated net revenue and those service contracts and post-shipment obligations are primarily within the Utility Solutions segment. Revenue from service contracts and post-shipment performance obligations is recognized when or as those obligations are satisfied. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations and on occasion will separately offer and price extended warranties that are separate performance obligations for which the associated revenue is recognized over-time based on the extended warranty period. The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. Within the Electrical Solutions segment, certain businesses require a portion of the transaction price to be paid in advance of transfer of control. Advance payments are not considered a significant financing component as they are received less than one year before the related performance obligations are satisfied. In addition, in the Utility Solutions segment, certain businesses offer annual maintenance service contracts that require payment at the beginning of the contract period. These payments are treated as a contract liability and are classified in Other accrued liabilities in the Condensed Consolidated Balance Sheets. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Condensed Consolidated Statements of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Condensed Consolidated Statements of Income on a straight-line basis over the expected term of the contract. The following table presents disaggregated revenue by business group. On January 1, 2022, we internally reorganized certain businesses within our Electrical Solutions segment to simplify the organization structure and align the organization to better serve our customers. This change had no impact to our reportable segments. In conjunction with this change, prior period amounts have been reclassified to conform to the organizational changes within the Electrical Solutions segment. Three Months Ended March 31, in millions 2022 2021 Net sales Electrical Products $ 227.7 $ 181.6 Connection and Bonding 143.9 116.1 Industrial Controls 73.0 58.5 Retail and Builder 59.7 67.9 Total Electrical Solutions $ 504.3 $ 424.1 Utility T&D Components 491.5 374.9 Utility Communications and Controls 160.3 157.3 Total Utility Solutions $ 651.8 $ 532.2 TOTAL $ 1,156.1 $ 956.3 The following table presents disaggregated revenue by geographic location (on a geographic basis, the Company defines "international" as operations based outside of the United States and its possessions): Three Months Ended March 31, in millions 2022 2021 Net sales United States $ 440.4 $ 366.8 International 63.9 57.3 Total Electrical Solutions $ 504.3 $ 424.1 United States 618.5 501.4 International 33.3 30.8 Total Utility Solutions $ 651.8 $ 532.2 TOTAL $ 1,156.1 $ 956.3 Contract Balances Our contract liabilities consist of advance payments for products as well as deferred revenue on service obligations and extended warranties. The current portion of deferred revenue is included in Other accrued liabilities and the non-current portion of deferred revenue is included in Other non-current liabilities in the Condensed Consolidated Balance Sheets. Contract liabilities were $23.0 million as of March 31, 2022 compared to $16.7 million as of December 31, 2021. The $6.3 million increase in our contract liabilities balance was primarily due to a $14.0 million net increase in current year deferrals primarily due to timing of advance payments on certain orders partially offset by the recognition of $7.7 million in revenue related to amounts that were recorded in contract liabilities at January 1, 2022. The Company has an immaterial amount of contract assets relating to performance obligations satisfied prior to payment that is recorded in Other long-term assets in the Condensed Consolidated Balance Sheets. Impairment losses recognized on our receivables and contract assets were immaterial for the three months ended March 31, 2022. Unsatisfied Performance Obligations As of March 31, 2022, the Company had approximately $420 million of unsatisfied performance obligations for contracts with an original expected length of greater than one year, primarily relating to long-term contracts of the Utility Solutions segment to deliver and install meters, metering communications and grid monitoring sensor technology. The Company expects that a majority of the unsatisfied performance obligations will be completed and recognized over the next two years.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company's reporting segments consist of the Electrical Solutions segment and the Utility Solutions segment. The Electrical Solutions segment comprises businesses that sell stock and custom products including standard and special application wiring device products, rough-in electrical products, connector and grounding products, lighting fixtures, components and other electrical equipment. The products are typically used in and around industrial, commercial and institutional facilities by electrical contractors, maintenance personnel, electricians, utilities, and telecommunications companies. In addition, certain of our businesses design and manufacture industrial controls and communication systems used in the non-residential and industrial markets. Many of these products are designed such that they can also be used in harsh and hazardous locations where a potential for fire and explosion exists due to the presence of flammable gasses and vapors. Harsh and hazardous products are primarily used in the oil and gas (onshore and offshore) and mining industries. There are also a variety of wiring devices, lighting fixtures and electrical products that have residential and utility applications, including residential products with Internet-of-Things ("IoT") enabled technologies. These products are primarily sold through electrical and industrial distributors, home centers, retail and hardware outlets, lighting showrooms and residential product oriented internet sites. Special application products are primarily sold through wholesale distributors to contractors, industrial customers and OEMs. The Utility Solutions segment consists of businesses that design, manufacture, and sell a wide variety of electrical distribution, transmission, substation, and telecommunications products. This includes utility transmission & distribution (T&D) components such as arresters, insulators, connectors, anchors, bushings, and enclosures. The Utility Solutions segment also offers solutions that serve the utility infrastructure, including smart meters, communications systems, and protection and control devices. Hubbell Utility Solutions supports the electrical distribution, electrical transmission, water, gas distribution, telecommunications, and solar and wind markets. Products are sold to distributors and directly to users such as utilities, telecommunication companies, industrial firms, construction and engineering firms.

Future amortization expense associated with these intangible assets is estimated to be $52.3 million for the remainder of 2022, $65.4 million in 2023, $61.4 million in 2024, $57.3 million in 2025, $53.7 million in 2026, and $48.7 million in 2027. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets useful life, or using a straight line method. Approximately 80% of the gross value of definite-lived intangible assets follow an accelerated amortization method. The organizational changes describe d in Note 3 - Revenue r esulted in a change in the Company's reporting units effective January 1, 2022 within the Electrical Solutions segment. As a result of the change in reporting units, the Company performed an interim goodwill impairment assessment prior to the change, for the reporting units within the Electrical Solutions segment. Because the changes did not affect the Utility Solutions segment, no interim goodwill impairment assessment was required for that segment. For the three reporting units within the Electrical Solutions segment, the Company elected to utilize the quantitative goodwill impairment testing process, as permitted in the accounting guidance, by comparing the estimated fair value of the reporting units to their carrying values. If the estimated fair value of a reporting unit exceeds its carrying value, no impairment exists. Goodwill impairment testing requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units and determining the fair value of each reporting unit. Significant judgment is required to estimate the fair value of reporting units including estimating future cash flows, determining appropriate discount rates and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. The Company uses internal discounted cash flow models to estimate fair value. These cash flow estimates are derived from historical experience, third party end market data, and future long-term business plans and include assumptions of future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. Significant changes in these estimates and assumptions could affect the determination of fair value and/or goodwill impairment for each reporting unit. The Company believes that its estimated aggregate fair value of its reporting units is reasonable when compared to the Company's market capitalization on the valuation date.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. Service-based and performance-based restricted stock awards granted by the Company are considered participating securities as these awards contain a non-forfeitable right to dividends. The following table sets forth the computation of earnings per share for the three months ended March 31, 2022 and 2021 (in millions, except per share amounts): Three Months Ended March 31, 2022 2021 Numerator: Net income from continuing operations attributable to Hubbell Incorporated $ 102.5 $ 73.3 Less: Earnings allocated to participating securities (0.3) (0.2) Net income from continuing operations available to common shareholders $ 102.2 $ 73.1 Net income from discontinued operations attributable to Hubbell Incorporated $ 77.7 $ 4.4 Less: Earnings allocated to participating securities (0.2) (0.1) Net income from discontinued operations available to common shareholders $ 77.5 $ 4.3 Net income attributable to Hubbell Incorporated $ 180.2 $ 77.7 Less: Earnings allocated to participating securities (0.5) (0.3) Net income available to common shareholders $ 179.7 $ 77.4 Denominator: Average number of common shares outstanding 54.1 54.2 Potential dilutive common shares 0.3 0.5 Average number of diluted shares outstanding 54.4 54.7 Basic earnings per share: Basic earnings per share from continuing operations $ 1.89 $ 1.34 Basic earnings per share from discontinued operations $ 1.43 $ 0.09 Basic earnings per share $ 3.32 $ 1.43 Diluted earnings per share: Diluted earnings per share from continuing operations $ 1.88 $ 1.33 Diluted earnings per share from discontinued operations $ 1.43 $ 0.09 Diluted earnings per share $ 3.31 $ 1.42 The Company did not have any significant anti-dilutive securities outstanding during the three months ended March 31, 2022 and 2021.

Standard Product Warranty Disclosure [Abstract]
Guarantees	Guarantees The Company records a liability equal to the fair value of guarantees in accordance with the accounting guidance for guarantees. When it is probable that a liability has been incurred and the amount can be reasonably estimated, the Company accrues for costs associated with guarantees. The most likely costs to be incurred are accrued based on an evaluation of currently available facts and, where no amount within a range of estimates is more likely, the minimum is accrued. As of March 31, 2022 and December 31, 2021, the fair value and maximum potential payment related to the Company’s guarantees were not material. The Company offers product warranties that cover defects on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known, or as historical experience indicates. Changes in the accrual for product warranties during the three months ended March 31, 2022 and 2021 are set forth below (in millions): 2022 2021 BALANCE AT JANUARY 1, (a) $ 66.1 $ 72.7 Provision 3.7 1.5 Expenditures/payments/other (3.5) (2.6) BALANCE AT MARCH 31, (a) $ 66.3 $ 71.6 (a) Refer to Note 7 – Other Accrued Liabilities and Note 8 – Other Non-Current Liabilities for a breakout of short-term and long-term warranties.

Fair Value Measurement

Fair Value Measurement	3 Months Ended
	Mar. 31, 2022
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Financial Instruments Financial instruments which potentially subject the Company to significant concentrations of credit loss risk consist of trade receivables, cash equivalents and investments. The Company grants credit terms in the normal course of business to its customers. Due to the diversity of its product lines, the Company has an extensive customer base including electrical distributors and wholesalers, electric utilities, equipment manufacturers, electrical contractors, telecommunication companies and retail and hardware outlets. As part of its ongoing procedures, the Company monitors the credit worthiness of its customers. Bad debt write-offs have historically been minimal. The Company places its cash and cash equivalents with financial institutions and limits the amount of exposure in any one institution. At March 31, 2022 our accounts receivable balance was $777.9 million, net of allowances of $11.5 million. During the three months ended March 31, 2022 our allowances increased approximately $0.9 million. Investments At March 31, 2022 and December 31, 2021, the Company had $63.5 million and $54.0 million, respectively, of available-for-sale municipal debt securities. These investments had an amortized cost of $64.4 million and $53.3 million, respectively. No allowance for credit losses related to our available-for-sale debt securities was recorded for the three months ended March 31, 2022. As of March 31, 2022 and December 31, 2021 the unrealized losses attributable to our available-for-sale debt securities was $1.1 million and $0.1 million, respectively. The fair value of available-for-sale debt securities with unrealized losses was $48.5 million at March 31, 2022 and $12.2 million at December 31, 2021. The Company also had trading securities of $21.8 million at March 31, 2022 and $24.5 million at December 31, 2021 that are carried on the balance sheet at fair value. Unrealized gains and losses associated with available-for-sale debt securities are reflected in Accumulated other comprehensive loss, net of tax, while unrealized gains and losses associated with trading securities are reflected in the results of operations. Fair value measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. The three broad levels of the fair value hierarchy are as follows: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions. The following table shows, by level within the fair value hierarchy, our financial assets and liabilities that are accounted for at fair value on a recurring basis at March 31, 2022 and December 31, 2021 (in millions): Asset (Liability) Quoted Prices in Active Markets for Identical Assets (Level 1) Quoted Prices in Unobservable inputs Total March 31, 2022 Money market funds (a) $ 100.4 $ — $ — $ 100.4 Available for sale investments — 63.5 — 63.5 Trading securities 21.8 — — 21.8 Deferred compensation plan liabilities (21.8) — — (21.8) Derivatives: Forward exchange contracts-Assets (b) — 0.1 — 0.1 Forward exchange contracts-(Liabilities) (c) — (0.3) — (0.3) TOTAL $ 100.4 $ 63.3 $ — $ 163.7 Asset (Liability) Quoted Prices in Quoted Prices in Unobservable inputs Total December 31, 2021 Money market funds (a) $ 58.5 $ — $ — $ 58.5 Available for sale investments — 54.0 — 54.0 Trading securities 24.5 — — 24.5 Deferred compensation plan liabilities (24.5) — — (24.5) Derivatives: Forward exchange contracts-Assets (b) — 0.5 — 0.5 TOTAL $ 58.5 $ 54.5 $ — $ 113.0 (a) Money market funds are reflected in Cash and cash equivalents in the Condensed Consolidated Balance Sheets. (b) Forward exchange contracts-Assets are reflected in Other current assets in the Condensed Consolidated Balance Sheets. (c) Forward exchange contracts-(Liabilities) are reflected in Other accrued liabilities in the Condensed Consolidated Balance Sheets. The methods and assumptions used to estimate the Level 2 fair values were as follows: Forward exchange contracts – The fair value of forward exchange contracts was based on quoted forward foreign exchange prices at the reporting date. Available-for-sale municipal bonds classified in Level 2 – The fair value of available-for-sale investments in municipal bonds is based on observable market-based inputs, other than quoted prices in active markets for identical assets. Deferred compensation plans The Company offers certain employees the opportunity to participate in non-qualified deferred compensation plans. A participant’s deferrals are invested in a variety of participant-directed debt and equity mutual funds that are classified as trading securities. The Company purchased $1.0 million and $1.2 million of trading securities related to these deferred compensation plans during the three months ended March 31, 2022 and 2021, respectively. As a result of participant distributions, the Company sold $2.4 million of these trading securities during the three months ended March 31, 2022 and $1.2 million during the three months ended March 31, 2021. The unrealized gains and losses associated with these trading securities are directly offset by the changes in the fair value of the underlying deferred compensation plan obligation. Long Term Debt As of March 31, 2022 and December 31, 2021, the carrying value of long-term debt, net of unamortized discount and debt issuance costs, was $1,436.1 million and $1,435.5 million, respectively. The estimated fair value of the long-term debt as of March 31, 2022 and December 31, 2021 was $1,422.1 million and $1,524.5 million, respectively, using quoted market prices in active markets for similar liabilities (Level 2).

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended
	Mar. 31, 2022
Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation As of March 31, 2022, the Company had various stock-based awards outstanding which were issued to executives and other key employees. The Company recognizes the grant-date fair value of all stock-based awards to employees over their respective requisite service periods (generally equal to an award’s vesting period), net of estimated forfeitures. A stock-based award is considered vested for expense attribution purposes when the employee’s retention of the award is no longer contingent on providing subsequent service. For those awards that vest immediately upon retirement eligibility, the Company recognizes compensation cost immediately for retirement-eligible individuals or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period. The Company’s long-term incentive program for awarding stock-based compensation includes a combination of restricted stock, stock appreciation rights (“SARs”), and performance shares of the Company’s common stock pursuant to the Hubbell Incorporated 2005 Incentive Award Plan as amended and restated (the "Award Plan"). Under the Award Plan, the Company may authorize up to 9.7 million shares of common stock to settle awards of restricted stock, performance shares, or SARs. The Company issues new shares to settle stock-based awards. During the three months ended March 31, 2022, the Company's grant of stock-based awards included restricted stock, SARs and performance shares. Each of the compensation arrangements is discussed below. Restricted Stock The Company issues various types of restricted stock awards, all of which are considered outstanding at the time of grant, as the award holders are entitled to dividends and voting rights. Unvested restricted stock awards are considered participating securities when computing earnings per share. Restricted stock grants are not transferable and are subject to forfeiture in the event of the recipient’s termination of employment prior to vesting. Restricted Stock Issued to Employees - Service Condition Restricted stock awards that vest based upon a service condition are expensed on a straight-line basis over the requisite service period. These awards generally vest either in three equal installments on each of the first three anniversaries of the grant date or on the third-year anniversary of the grant date. The f air value of these awards is measured by the average of the high and low trading prices of the Company’s common stock on the most recent trading day immediately preceding the grant date (“measurement date”). In February 2022, the Company granted 55,457 restricted stock awards with a fair value per share of $185.87. Stock Appreciation Rights SARs grant the holder the right to receive, once vested, the value in shares of the Company's common stock equal to the positive difference between the grant price, as determined using the mean of the high and low trading prices of the Company’s common stock on the measurement date, and the fair market value of the Company’s common stock on the date of exercise. This amount is payable in shares of the Company’s common stock. SARs vest and become exercisable in three equal installments during the first three years following the grant date and expire ten years from the grant date. In February 2022, the Company granted 137,099 SAR awards. The fair value of each SAR award was measured using the Black-Scholes option pricing model. The following table summarizes the weighted-average assumptions used in estimating the fair value of the SARs granted during the first three months of 2022: Grant Date Expected Dividend Yield Expected Volatility Risk Free Interest Rate Expected Term Weighted Avg. Grant Date Fair Value of 1 SAR February 2022 2.1% 27.4% 1.8% 4.9 years $39.25 The expected dividend yield was calculated by dividing the Company’s expected annual dividend by the average stock price for the past three months. Expected volatilities are based on historical volatilities of the Company’s stock for a period consistent with the expected term. The expected term of SARs granted was based upon historical exercise behavior of SARs. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the award. Performance Shares Performance shares represent the right to receive a share of the Company’s common stock subject to the achievement of certain market or performance conditions established by the Company’s Compensation Committee and measured over a three-year period. Partial vesting in these awards may occur after separation from the Company for retirement eligible employees. Shares are not vested until approved by the Company’s Compensation Committee. Performance Shares - Market Condition In February 2022, the Company granted 14,076 p erformance shares that will vest subject to a market condition and service condition through the performance period. The market condition associated with the awards is the Company's total shareholder return ("TSR") compared to the TSR generated by the companies that comprise the S&P Capital Goods 900 index over a three year performance per iod. Performance at target will result in vesting and issuance of the number of performance shares granted, equal to 100% payout. Performance below or above target can result in issuance in the range of 0%-200% of the number of shares granted. Exp ense is recognized irrespective of the market condition being achieved. The fair value of the performance share awards with a market condition for the 2022 grant was determined based upon a lattice model. The following table summarizes the related assumptions used to determine the fair values of the performance share awards with a market condition granted during February 2022: Grant Date Stock Price on Measurement Date Dividend Yield Expected Volatility Risk Free Interest Rate Expected Term Weighted Avg. Grant Date Fair Value February 2022 $185.87 2.3% 39.7% 1.6% 2.9 years $221.94 Expected volatilities are based on historical volatilities of the Company’s and members of the peer group's stock over the expected term of the award. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the expected term of the award. Performance Shares - Performance Condition In February 2022, the Company granted 28,628 performance shares that will vest subject to an internal Company-based performance condition and service requirement. Fifty percent of these performance shares granted will vest based on Hubbell’s compounded annual growth rate of Net sales as compared to that of the companies that comprise the S&P Capital Goods 900 index. Fifty percent of these performance shares granted will vest based on achieved operating profit margin performance as compared to internal targets. Each of these performance conditions is measured over the same three-year performance period. The cumulative result of these performance conditions can result in a number of shares earned in the range of 0% - 200% of the target number of shares granted. The fair value of the award is measured based upon the average of the high and low trading prices of the Company's common stock on the measurement date reduced by the present value of dividends expected to be paid during the requisite service period. The Company expenses these awards on a straight-line basis over the requisite service period and including an assessment of the performance achieved to date. The weighted average fair value per share was $174.48 for the awards granted in the first quarter of 2022. Grant Date Fair Value Performance Period Payout Range February 2022 $174.48 Jan 2022 - Dec 2024 0-200%

The pandemic has had, and may continue to have, a significant effect on global economic conditions. U.S. Federal, state, local, and foreign governments have reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. and global economies. The extent to which the coronavirus pandemic will continue to affect our business, operations, supply chains, and our financial results will depend on numerous evolving factors that we may not be able to accurately predict and which may cause the actual results to differ from the estimates and assumptions we are required to make in the preparation of financial statements according to GAAP.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are effective for all entities beginning on March 12, 2020 through December 31, 2022. The Company may elect to apply the amendments prospectively through December 31, 2022. The Company has not adopted this ASU as of March 31, 2022. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption. In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." ASU 2021-08 requires an acquirer to recognize and measure contract assets and contract liabilities, including deferred revenue, acquired in a business combination in accordance with Revenue from Contracts with Customers (Topic 606) as if the acquirer had originated the contracts at the date of the business combination. The provisions of ASU 2021-08 are effective for interim periods and fiscal years beginning after December 15, 2022, with early adoption permitted. If early adopted, the provisions of ASU 2021-08 apply retrospectively to all business combinations that occurred on or after the first day of the fiscal year in which the standard is adopted. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.
