Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 net cash consideration of $332.8 million. The C&I Lighting business had sales of $509.4 million in 2021 as part of the Electrical Solutions segment and designs, manufactures, and sells LED lighting and control solutions for commercial and industrial customers. As a result of the agreement, the C&I Lighting business met the criteria set forth in ASC 205-20 to be presented as a discontinued operation. The C&I Lighting business' results of operations and the related cash flows have been presented as income from discontinued operations in the Consolidated Statements of Income and cash flows from discontinued operations in the Consolidated Statements of Cash Flows, respectively, for all periods presented. See Note 2, Discontinued Operations, to the Consolidated Financial Statements for further information. Principles of Consolidation The Consolidated Financial Statements include all wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The Company participates in two joint ventures that have been consolidated in accordance with the consolidation accounting guidance. An analysis is performed to determine which reporting entity, if any, has a controlling financial interest in a variable interest entity (“VIE”) with a primarily qualitative analysis. The qualitative analysis is based on identifying the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance (the “power criterion”) and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE (the “losses/benefit criterion”). The party that meets both these criteria is deemed to have a controlling financial interest. The party with the controlling financial interest is considered to be the primary beneficiary and as a result is required to consolidate the VIE. The Company has a 50% interest in a joint venture in Hong Kong, established as Hubbell Asia Limited (“HAL”). The principal objective of HAL is to manage the operations of its wholly-owned manufacturing company in China. Under the accounting guidance, the Company is the primary beneficiary of HAL and as a result consolidates HAL. This determination is based on the fact that HAL’s sole business purpose is to manufacture product exclusively for the Company (the power criterion) and the Company is financially responsible for ensuring HAL maintains a fixed operating margin (the losses/benefit criterion). The consolidation of HAL is not material to the Company’s consolidated financial statements. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could differ from the estimates that are used. 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. Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the consolidated statements of financial position. Refer to Note 2, "Discontinued Operations," of the notes to Consolidated Financial Statements for further information. In conjunction with the C&I Lighting Business being classified as held for sale, depreciation and amortization ceased. Revenue Recognition 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 in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is 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 Consolidated Balance Sheet. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statement of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statement of Income on a straight line basis over the expected term of the contract. The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately 1% of gross sales. Shipping and Handling Costs The Company records shipping and handling costs as part of Cost of goods sold in the Consolidated Statement of Income. Foreign Currency Translation The assets and liabilities of international subsidiaries are translated to U.S. dollars at exchange rates in effect at the end of the year, and income and expense items are translated at average exchange rates in effect during the year. The effects of exchange rate fluctuations on the translated amounts of foreign currency assets and liabilities are included as translation adjustments in Accumulated other comprehensive loss within Hubbell shareholders’ equity. Gains and losses from foreign currency transactions are included in results of operations. Cash and Cash Equivalents The carrying value of cash equivalents approximates fair value. Cash equivalents consist of highly liquid investments with original maturities to the Company of three months or less. Investments Investments in debt and equity securities are classified by individual security as available-for-sale, held-to-maturity or trading securities. Our available-for-sale securities, consisting of municipal bonds, are carried on the balance sheet at fair value with current period adjustments to carrying value recorded in Accumulated other comprehensive loss within Hubbell shareholders’ equity, net of tax. Realized gains and losses are recorded in income in the period of sale. The Company’s trading securities are carried on the balance sheet at fair value and consist primarily of debt and equity mutual funds. Gains and losses associated with these trading securities are reflected in the results of operations. The Company did not have any investments classified as held-to-maturity as of December 31, 2022 and 2021. Accounts Receivable and Allowances Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is based on an estimated amount of probable credit losses in existing accounts receivable. The allowance is calculated based upon a combination of historical write-off experience, fixed percentages applied to aging categories and specific identification based upon a review of past due balances and problem accounts. Account balances are charged off against the allowance when it is determined that internal collection efforts should no longer be pursued. The Company also maintains a reserve for credit memos and cash discounts which are principally calculated based upon historical experience, specific customer agreements, as well as anticipated future trends. Inventories Inventories are stated at the lower of cost or market value. Approximately 60% of total net inventory value is determined utilizing the last-in, first-out (LIFO) method of inventory accounting. The cost of foreign inventories and certain domestic inventories is determined utilizing average cost or first-in, first-out (FIFO) methods of inventory accounting. Reserves for excess and obsolete inventory are provided based on current assessments about future demand compared to on-hand quantities. Property, Plant, and Equipment Property, plant, and equipment values are stated at cost less accumulated depreciation. Maintenance and repair expenditures that do not significantly increase the life of an asset are charged to expense when incurred. Property, plant, and equipment placed in service prior to January 1, 1999 are depreciated over their estimated useful lives, principally, using accelerated methods. Assets placed in service subsequent to January 1, 1999 are depreciated over their estimated useful lives, using straight-line methods. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Gains and losses arising on the disposal of property, plant and equipment are included in Operating income in the Consolidated Statement of Income. Capitalized Computer Software Costs Capitalized computer software costs, net of amortization, were $7.0 million and $10.8 million at December 31, 2022 and 2021, respectively. This balance is reflected in Other long-term assets in the Consolidated Balance Sheet. Capitalized computer software is for internal use and costs primarily consist of purchased materials, external services and salary costs for personnel dedicated to the projects. Software is amortized on a straight-line basis over appropriate periods, generally between three Goodwill and Other Intangible Assets Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Indefinite-lived intangible assets and goodwill are subject to annual impairment testing using the specific guidance and criteria described in the accounting guidance. The Company performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. The accounting guidance provides entities an option of performing a qualitative assessment (a "step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to quantitative goodwill impairment testing process as prescribed in the guidance. The Company applied the "step-zero" test to one of its four reporting units. Based on that qualitative assessment, the Company concluded it was more-likely-than-not that the fair value of this reporting unit exceeded its carrying value and therefore, further quantitative analysis was not required. For the other three reporting units the Company has elected to utilize the quantitative goodwill impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values. If the fair value of the 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 judgments required to estimate the fair value of reporting units include estimating future discounted 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, impacts to the supply chain and higher inflation. We use 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 on future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. 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. 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. 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. As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit's carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. Additionally, the Company did not have any reporting units with zero or negative carrying amounts. The Company has not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002. The Company’s intangible assets consist primarily of customer relationships, tradenames, developed technology and patents. Intangible assets with definite lives are amortized over periods generally ranging from 5-30 years. 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. These definite lived intangibles are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The Company did not record any material impairments related to its definite lived intangible assets in 2022, 2021 or 2020. The Company also has some tradenames that are considered to be indefinite-lived intangible assets. These indefinite-lived intangible assets are not amortized and are tested for impairment annually, unless circumstances dictate the need for more frequent assessment. The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues, discount rates, royalty rates, and other assumptions, including assumptions about secular economic and market conditions, such as the potential continuing effects of the COVID-19 pandemic. Significant changes in these estimates and assumptions could affect the determination of fair value and/or impairment for each indefinite-lived intangible asset. As of April 1, 2022, the impairment testing resulted in fair values for each indefinite-lived intangible asset that significantly exceeded the carrying values and there were no indefinite-lived intangible assets at risk of failing the quantitative impairment test. The Company did not record any impairments related to indefinite-lived intangible assets in 2022, 2021 and 2020. Other Long-Lived Assets The Company reviews depreciable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If such a change in circumstances occurs, the related estimated future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition is compared to the carrying amount. If the sum of the expected cash flows is less than the carrying amount, an impairment charge is recorded. The impairment charge is measured as the amount by which the carrying amount exceeds the fair value of the asset. The fair value of impaired assets is determined using expected cash flow estimates, quoted market prices when available and appraisals as appropriate. The Company did not record any material impairment charges in 2022, 2021 or 2020. Leases We determine if an arrangement is a lease at inception. Operating leases are included as ROU assets within other long-term assets, other accrued liabilities, and other non-current liabilities in our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use an implicit rate when readily determinable. For leases existing as of January 1, 2019, we have elected to use the remaining lease term as of the adoption date in determining the incremental borrowing rate. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Additionally, for our vehicle leases, we apply a portfolio approach regarding the assumed lease term. Accrued Insurance The Company retains a significant portion of the risks associated with workers’ compensation, medical, automobile and general liability insurance. The Company estimates self-insurance liabilities using a number of factors, including historical claims experience, demographic factors, and other actuarial assumptions. The accrued liabilities associated with these programs are based on the Company’s estimate of the ultimate costs to settle known claims as well as claims incurred but not reported as of the balance sheet date. The Company periodically reviews the assumptions with a third party actuary to determine the adequacy of these self-insurance reserves. Accrued Warranty The Company offers product warranties which 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. Income Taxes The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely examine the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. The Company makes adequate provisions for best estimates of exposures on previously filed tax returns. Deferred income taxes are recognized for the tax consequence of differences between financial statement carrying amounts and the tax basis of assets and liabilities by applying the currently enacted statutory tax rates in accordance with the accounting guidance for income taxes. The effect of a change in statutory tax rates is recognized in the period that includes the enactment date. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that a portion or all of the deferred tax asset will not be realized. The Company uses factors to assess the likelihood of realization of deferred tax assets such as the forecast of future taxable income and available tax planning that could be implemented to realize the deferred tax assets. In addition, the accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of the tax position taken or expected to be taken in a tax return. For any amount of benefit to be recognized, it must be determined that it is more-likely-than-not that a tax position will be sustained upon examination by taxing authorities based on the technical merits of the position. The amount of benefit to be recognized is based on the Company’s assertion of the most likely outcome resulting from an examination, including resolution of any related appeals or litigation processes. Companies are required to reflect only those tax positions that are more-likely-than-not to be sustained. See Note 14 — Income Taxes for additional information. Research and Development Research and development expenditures represent costs to discover and/or apply new knowledge in developing a new product, process, or in bringing about a significant improvement to an existing product or process. Research and development expenses are recorded as a component of Cost of goods sold. Expenses for research and development were approximatel y 2% o f Net Sales in each of 2022 and 2021 and 3% in 2020. Government Assistance We have adopted Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance, which requires footnote disclosure of assistance received from government entities. We record amounts received from government entities as a reduction of the associated expense. Amounts received related to depreciable assets are recognized as a reduction to depreciation expense. The total impact of government assistance was not material to the Company in 2022, and prior periods presented. Retirement Benefits The Company maintains various defined benefit pension plans for some of its U.S. and foreign employees. The accounting guidance for retirement benefits requires the Company to recognize the funded status of its defined benefit pension and postretirement plans as an asset or liability in the Consolidated Balance Sheet. Gains or losses, prior service costs or credits, and transition assets or obligations that have not yet been included in net periodic benefit cost as of the end of the year are recognized as components of Accumulated other comprehensive loss, net of tax, within Hubbell shareholders’ equity. The Company’s policy is to fund pension costs within the ranges prescribed by applicable regulations. In addition to providing defined benefit pension benefits, the Company provides health care and life insurance benefits for some of its active and retired employees. The Company’s policy is to fund these benefits through insurance premiums or as actual expenditures are made. See also Note 12 — Retirement Benefits. Earnings Per Share Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends. As a result, the earnings per share accounting guidance requires the Company to use the two-class method for calculating earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities. Basic earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares of common stock outstanding. Earnings per diluted share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding of common stock plus the incremental shares outstanding assuming the exercise of dilutive stock options, stock appreciation rights and performance shares. See also Note 19 — Earnings Per Share. Stock-Based Compensation The Company recognizes the grant-date fair value of all stock-based awards on a straight-line basis over their respective requisite service periods (generally equal to an award’s vesting period). A stock-based award is considered vested for expense attribution purposes when the retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company generally recognizes compensation cost immediately for awards granted to 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 expense is recorded in Cost of goods sold and S&A expense in the Consolidated Statement of Income based on the recipients’ respective functions within the organization. The Company records deferred tax assets for awards that will result in deductions on its tax returns, based upon the amount of compensation cost recognized and the statutory tax rate in the jurisdiction in which it will receive a deduction. See also Note 18 — Stock-Based Compensation. 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. In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the temporary accounting rules under Topic 848 to December 31, 2024. 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 C&I Lighting business to GE Current, a Daintree Company, for total net cash consideration of $332.8 million. We have concluded the divestiture 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 Consolidated Financial Statements for all periods presented. The assets and liabilities of this business are also presented as held for sale in the Consolidated Balance Sheets for the year ended December 31, 2021. The C&I 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 provides 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 acts as a supplier of finished goods and component parts to the C&I Lighting business after the completion of the sale. Income from the TSA and supply agreement was $13.3 million for the year ended December 31, 2022 and was recorded in Other Income in the 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: Year Ended December 31, (in millions) 2022 2021 2020 Net sales $ 29.1 $ 509.4 $ 503.5 Cost of goods sold 27.8 403.4 385.6 Gross profit 1.3 106.0 117.9 Selling & administrative expenses 17.3 88.5 85.1 Operating (Loss) income (16.0) 17.5 32.8 Gain on disposal of business 73.9 — — Other expense (1.5) (4.1) (4.0) Income from discontinued operations before income taxes 56.4 13.4 28.8 Provision (benefit) for income taxes 21.8 (21.1) 7.6 Income from discontinued operations, net of taxes $ 34.6 $ 34.5 $ 21.2 Income from discontinued operations, net of taxes for the year ended December 31, 2022 and December 31, 2021 includes pre-tax transaction and separation costs of $8.8 million and $7.0 million, respectively. The provision for income taxes on discontinued operations in 2022 includes a correction of $19 million of income tax expense recognized in the fourth quarter of 2022 that should have been recognized in the first quarter of 2022. The Company evaluated the materiality of the adjustment to prior-period financial statements and concluded the effect of the adjustment was immaterial. In addition, a one-time tax benefit of $25.1 million related to book-to-tax basis differences of the business was recorded in the year ended December 31, 2021. The following table presents balance sheet information for assets and liabilities held for sale: At December 31, (in millions) 2021 Cash and cash equivalents $ 0.7 Accounts receivable 83.1 Inventories, net 89.8 Other current assets 5.9 Assets held for sale - current $ 179.5 Property, Plant, and Equipment, net 77.7 Goodwill 50.2 Other Intangible assets, net 37.3 Other long-term assets 11.9 Assets held for sale - non-current $ 177.1 Accounts payable 50.2 Accrued salaries, wages and employee benefits 8.5 Accrued insurance 3.9 Other accrued liabilities 28.7 Liabilities held for sale - current $ 91.3 Other Non-Current Liabilities 18.8 Liabilities held for sale - non-current $ 18.8

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. Approximately three-fourths of the Company's Net sales are to distributors who then sell directly into our end markets. Within the Utility Solutions segment, our businesses sell to distributors, with the majority of sales to the utility end markets and also directly into transmission and distribution utility markets. 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 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 Consolidated Balance Sheets. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statements of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the 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.

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 Consolidated Balance Sheet. Contract liabilities were $45.8 million as of December 31, 2022 compared to $16.7 million as of December 31, 2021. The $29.1 million increase in our contract liabilities balance was primarily due to a $21.8 million net increase in current year deferrals primarily due to timing of advance payments on certain orders and a $20.1 million increase due to acquisitions, partially offset by the recognition of $12.8 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 in the twelve months ended December 31, 2022. See Note 1 – Significant Accounting Policies in the Notes to Consolidated Financial Statements for additional information. Unsatisfied Performance Obligations The Company has elected the practical expedient to disclose only the value of unsatisfied performance obligations for contracts with an original expected length greater than one year. As of December 31, 2022, the Company had approximately $320 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 Aclara business (within 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 2 years.

Business Combination and Asset Acquisition [Abstract]
Business Acquisitions and Dispositions	Business Acquisitions and Dispositions 2022 Acquisitions In the third quarter of 2022, the Company acquired all of the issued and outstanding membership interests of PCX Holdings LLC ("PCX") for a cash purchase price of approximately $112.8 million, net of cash acquired. PCX is a leading designer and manufacturer of factory built modular power solutions for applications in the data center market. This business is reported in the Electrical Solutions segment. We have recognized intangible assets of $49.1 million and goodwill of $77.4 million as a result of this acquisition. The intangible assets of $49.1 million consist primarily of customer relationships, backlog and a tradename and will be amortized over a weighted average period of approximately 11 years. All of the goodwill is expected to be deductible for tax purposes. In the third quarter of 2022, the Company also acquired all of the issued and outstanding membership interests of Ripley Tools, LLC and Nooks Hill Road, LLC, collectively referred to as Ripley Tools, for a cash purchase price of approximately $50.1 million, net of cash acquired. Ripley Tools is a leading manufacturer of cable and fiber prep tools and test equipment that services both the utility and communications markets. This business is reported in the Utility Solutions segment. We have recognized intangible assets of $18.2 million and goodwill of $23.8 million as a result of this acquisition. The intangible assets of $18.2 million consist primarily of customer relationships and a tradename, and will be amortized over a weighted average period of approximately 17 years. Substantially all of the goodwill is expected to be deductible for tax purposes. In the fourth quarter of 2022, the Company also acquired all of the issued and outstanding equity interests of REF Automation Limited and REF Alabama Inc. (collectively "REF") for a cash purchase price of $14.1 million, net of cash acquired, subject to customary purchase price adjustments. REF designs and manufactures electrical power components utilizing high-volume precision machining, as well as custom fabricated structural products and assemblies for the OEM, industrial and renewables markets. This business is reported in the Electrical Solutions segments. We have recognized goodwill of $10.2 million as a result of the acquisition. None of the goodwill associated with this acquisition is expected to be deductible for tax purposes. These business acquisitions have been accounted for as business combinations and have resulted in the recognition of goodwill. The goodwill relates to a number of factors implied in the purchase prices, including the future earnings and cash flow potential of the businesses as well as the complementary strategic fit and resulting synergies that such business acquisitions bring to the Company’s existing operations. Allocation of Consideration Transferred to Net Assets Acquired The following table presents the determination of the fair value of identifiable assets acquired and liabilities assumed from the Company's 2022 acquisitions. Fair value est imates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations. The following table summarizes the fair values of the assets acquired and liabilities assumed as of the respective date of acquisition for all transactions (in millions): Tangible assets acquired $ 41.4 Intangible assets 67.3 Goodwill 111.4 Other liabilities assumed (43.0) Total Estimate of Consideration Transferred, Net of Cash Acquired 177.1 The Consolidated Financial Statements include the results of operations of the acquired businesses from their respective dates of acquisition. Net sales and earnings related to these acquisitions for the year ended December 31, 2022 were not significant to the consolidated results. Pro forma information related to these acquisitions has not been included because the impact to the Company's consolidated results of operations was not material. Dispositions In June of 2021, the Company completed the sale of the Consumer Analytics Solutions business for $9.8 million. The Consumer Analytics Solutions business was part of Aclara and was previously included in the Utility Solutions segment. Upon disposition, the Consumer Analytics Solutions business had assets of $15.9 million, including definite-lived intangibles of $8.7 million (primarily customer relationships and developed technology), goodwill of $1.9 million and total liabilities of $1.5 million (primarily composed of deferred revenue). As a result of the sale of the Consumer Analytics Solutions business, we recognized a pre-tax loss of $6.9 million that is included in Total other expense in the Consolidated Statement of Income.

Pension and Other Postretirement Benefits Cost (Reversal of Cost) [Abstract]
Retirement Benefits	Retirement Benefits The Company has funded and unfunded non-contributory U.S. and foreign defined benefit pension plans. Benefits under these plans are generally provided based on either years of service and final average pay or a specified dollar amount per year of service. The U.S. defined benefit pension plan has been closed to new participants since 2004, while the Canadian and UK defined benefit pension plans have been closed to new entrants since 2006 and 2007, respectively. These U.S., Canadian and UK employees are eligible instead for defined contribution plans. The Company also has a number of health care and life insurance benefit plans covering eligible employees who reached retirement age while working for the Company. These benefits have been discontinued for substantially all future retirees. The Company anticipates future cost-sharing charges for its discontinued plans that are consistent with past practices. The Company uses a December 31 measurement date for all of its plans. In 2020 and 2022, the Company recognized a settlement loss in continuing operations relating to retirees that elected to receive lump-sum distributions from the Company's defined benefit pension plans of $7.6 million and $7.0 million, respectively. This charge was the result of lump-sum payments which exceeded the threshold for settlement accounting under U.S. GAAP in each year . In 2019, the Company approved amendments to one of its domestic qualified defined benefit pension plans, which froze service accruals for nearly all active participants within the plan effective January 1, 2020. As a result of the amendment, the Company recognized a $0.3 million curtailment charge, net of tax. Effective January 1, 2020, the amortization of unrecognized gains and losses of all of the Company's qualified defined benefit pension plans is recognized over the remaining life expectancy of participants, as nearly all participants are considered inactive as a result of plan amendments. The Company's U.S. defined benefit pension plans were approximately 90% of the $670.8 million total pension benefit obligations at December 31, 2022. The following table sets forth the reconciliation of beginning and ending balances of the benefit obligations and the plan assets for the Company’s defined benefit pension and other benefit plans at December 31, (in millions): Pension Benefits Other Benefits 2022 2021 2022 2021 Change in benefit obligation Benefit obligation at beginning of year $ 937.7 $ 994.2 $ 18.9 $ 23.2 Service cost 0.9 1.0 — — Interest cost 28.0 23.8 0.5 0.6 Plan participants’ contributions — — — — Amendments — 3.6 — — Actuarial loss/(gain) (214.2) (22.0) (2.2) (4.2) Curtailment gain — — — — Settlements (22.5) (0.1) — — Currency impact (10.5) (0.9) — — Other (0.5) (0.3) — — Benefits paid (48.1) (61.6) (1.3) (0.7) Benefit obligation at end of year $ 670.8 $ 937.7 $ 15.9 $ 18.9 Change in plan assets Fair value of plan assets at beginning of year $ 765.6 $ 805.1 $ — $ — Actual return on plan assets (186.6) 15.6 — — Employer contributions 19.8 7.9 1.3 0.7 Plan participants’ contributions — — — — Settlements (22.5) (0.1) — — Currency impact (12.8) (1.3) — — Benefits paid (48.1) (61.6) (1.3) (0.7) Fair value of plan assets at end of year $ 515.4 $ 765.6 $ — $ — FUNDED STATUS $ (155.4) $ (172.1) $ (15.9) $ (18.9) Amounts recognized in the consolidated balance sheet consist of: Prepaid pensions (included in Other long-term assets) $ 6.8 $ 24.8 $ — $ — Accrued benefit liability (short-term and long-term) (162.2) (196.9) (15.9) (18.9) NET AMOUNT RECOGNIZED IN THE CONSOLIDATED BALANCE SHEET $ (155.4) $ (172.1) $ (15.9) $ (18.9) Amounts recognized in Accumulated other comprehensive loss (income) consist of: Net actuarial loss (gain) $ 244.4 $ 263.1 $ (5.5) $ (3.4) Prior service cost (credit) 6.3 6.9 — — NET AMOUNT RECOGNIZED IN ACCUMULATED OTHER COMPREHENSIVE LOSS $ 250.7 $ 270.0 $ (5.5) $ (3.4) The accumulated benefit obligation for all defined benefit pension plans was $670.8 million and $937.7 million at December 31, 2022 and 2021, respectively. Information with respect to plans with accumulated benefit obligations in excess of plan assets is as follows, (in millions): 2022 2021 Projected benefit obligation $ 468.0 $ 817.7 Accumulated benefit obligation $ 468.0 $ 817.7 Fair value of plan assets $ 305.8 $ 620.7 The following table sets forth the components of pension and other benefit costs for the years ended December 31, (in millions): Pension Benefits Other Benefits 2022 2021 2020 2022 2021 2020 Components of net periodic benefit cost: Service cost $ 0.9 $ 1.0 $ 1.2 $ — $ — $ — Interest cost 28.0 23.8 28.0 0.5 0.6 0.7 Expected return on plan assets (30.8) (36.5) (33.9) — — — Amortization of prior service cost (credit) 0.4 0.2 0.2 — — (0.4) Amortization of actuarial losses (gains) 10.8 10.8 9.8 (0.2) (0.1) (0.1) Curtailment and settlement losses 8.8 — 7.5 — — — Net periodic benefit cost $ 18.1 $ (0.7) $ 12.8 $ 0.3 $ 0.5 $ 0.2 Changes recognized in other comprehensive loss (income), before tax: Current year net actuarial loss (gain) $ 2.6 $ (1.4) $ 28.6 $ (2.2) $ (4.1) $ 0.1 Current year prior service credit — 3.6 — — — — Amortization of prior service (cost) credit (0.4) (0.2) (0.2) — — 0.4 Amortization of net actuarial (losses) gains (10.8) (10.8) (9.8) 0.2 0.1 0.1 Currency impact (2.0) (0.2) 0.1 — — — Settlement adjustment (8.8) — (7.6) — — — Curtailment adjustments — — 0.1 — — — Total recognized in other comprehensive loss (19.4) (9.0) 11.2 (2.0) (4.0) 0.6 TOTAL RECOGNIZED IN NET PERIODIC PENSION COST AND OTHER COMPREHENSIVE LOSS $ (1.3) $ (9.7) $ 24.0 $ (1.7) $ (3.5) $ 0.8 During 2022, the Company recognized $7.0 million of settlement losses in continuing operations and $1.8 million of settlement losses in discontinued operations. Those settlement losses are the result of lump-sum distributions from the Company's defined benefit pension plans which exceeded the threshold for settlement accounting under U.S. GAAP for the year. The Company also maintains four primary defined contribution pension plans. The total cost of the Company's defined contribution plans was $25.8 million in 2022, $23.3 million in 2021 and $21.0 million in 2020, excluding the employer match for the 401(k) plan. This cost is not included in the above net periodic benefit cost for the defined benefit pension plans. In 2020, 2021 and 2022 the Company participated in one multi-employer defined benefit pension plan. The Company’s total contributions while participating in this plan was $0.2 million in each of these years. The risks of participating in multi-employer plans are different from single-employer plans in that assets contributed are pooled and may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may have to be assumed by the remaining participant employers. If we choose to stop participating in a multi-employer plan we may be required to pay those plans a withdrawal liability based on the unfunded status of the plan. Assumptions The following assumptions were used to determine the projected benefit obligations at the measurement date and the net periodic benefit cost for the year: Pension Benefits Other Benefits 2022 2021 2020 2022 2021 2020 Weighted-average assumptions used to determine benefit obligations at December 31, Discount rate 5.46 % 2.79 % 2.47 % 5.50 % 2.90 % 2.50 % Rate of compensation increase 0.08 % 0.08 % 0.24 % 3.93 % 3.87 % 3.99 % Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31, Discount rate 2.79 % 2.47 % 3.17 % 2.90 % 2.50 % 3.30 % Expected return on plan assets 4.59 % 4.66 % 4.69 % N/A N/A N/A Rate of compensation increase 0.08 % 0.24 % 2.94 % 3.87 % 3.99 % 4.00 % At the end of each year, the Company determines the appropriate expected return on assets for each plan based upon its strategic asset allocation (see discussion below). In making this determination, the Company utilizes expected returns for each asset class based upon current market conditions and expected risk premiums for each asset class. The Company also determines the discount rate to be used to calculate the present value of pension plan liabilities at the end of each year. The discount rate for the Company’s U.S. and Canadian pension plans is determined by matching the expected cash flows associated with its benefit obligations to the expected cash flows of a hypothetical portfolio of high quality, fixed income debt instruments with maturities that closely match the expected funding period of its pension liabilities. As of December 31, 2022, the Company used a discount rate of 5.50% for its U.S. pension plans compared to a discount rate of 2.90% used in 2021. For its Canadian pension plan, the Company used a discount rate of 5.01% as of December 31, 2022 compared to a 2.98% discount rate used in 2021. For its UK pension plan the discount rate was derived using a full yield curve and uses plan specific cash flows. The derived discount rate is the single discount rate equivalent to discounting these liability cash flows at the term-dependent spot rate of AA corporate bonds. This methodology resulted in a December 31, 2022 discount rate for the UK pension plan of 5.00% as compared to a discount rate of 1.80% used in 2021. In 2020 we used the Pri-2012 mortality table to calculate the present value of our pension plan liabilities and adopted the MP-2020 projection scale, and in 2021 and 2022 we used the Pri-2012 mortality table and adopted the MP-2021 projection scale The Pri-2012 mortality table with adjustment for collar as appropriate and generational projection from 2012 using Scale MP-2021 was chosen as the best estimate based on the observed and anticipated experience of the plans after considering alternative tables. These changes did not have a material impact to the projected benefit obligation of our U.S. plans upon remeasurement. The rate of compensation increase assumption reflects the Company’s actual experience and best estimate of future increases. The assumed health care cost trend rates used to determine the projected postretirement benefit obligation are as follows: Other Benefits 2022 2021 2020 Assumed health care cost trend rates at December 31, Health care cost trend assumed for next year 7.0 % 6.2 % 6.4 % Rate to which the cost trend is assumed to decline 5.0 % 5.0 % 5.0 % Year that the rate reaches the ultimate trend rate 2031 2028 2028 Plan Assets The Company’s combined targeted 2023 weighted average asset allocation for domestic and foreign pension plans and the actual weighted average asset allocation for domestic and foreign pension plans at December 31, 2022 and 2021 by asset category are as follows: Percentage of Plan Assets Target Actual Asset Category 2023 2022 2021 Equity securities 32 % 23 % 22 % Debt securities & Cash 68 % 77 % 77 % Alternative Investments — % — % 1 % TOTAL 100 % 100 % 100 % At the end of each year, the Company estimates the expected long-term rate of return on pension plan assets based on the strategic asset allocation for its plans. In making this determination, the Company utilizes expected rates of return for each asset class based upon current market conditions and expected risk premiums for each asset class. The Company has written investment policies and asset allocation guidelines for its domestic and foreign pension plans. In establishing these policies, the Company has considered that its various pension plans are a major retirement vehicle for most plan participants and has acted to discharge its fiduciary responsibilities with regard to the plans solely in the interest of such participants and their beneficiaries. The goal underlying the establishment of the investment policies is to provide that pension assets shall be invested in a prudent manner and so that, together with the expected contributions to the plans, the funds will be sufficient to meet the obligations of the plans as they become due. To achieve this result, the Company conducts a periodic strategic asset allocation study to form a basis for the allocation of pension assets between various asset categories. Specific policy benchmark percentages are assigned to each asset category with minimum and maximum ranges established for each. The assets are then tactically managed within these ranges. Derivative investments include futures contracts used by the plan to adjust the level of its investments within an asset allocation category. The actual and target percentages reported in the preceding table reflect the economic exposure to each asset category, including the impact of derivative positions. All futures contracts are 100% supported by cash or cash equivalent investments. At no time may derivatives be utilized to leverage the asset portfolio. At December 31, 2022 and 2021, there were no holdings of Company stock in pension plan assets. The Company’s other post-employment benefits are unfunded; therefore, no asset information is reported.

The objective of these funds is to achieve the desired capital appreciation or fixed income as applicable with lower volatility than either traditional equity or fixed income securities. Contributions In 2021, there were no contributions to the Company's U.S. qualified plans required by the Pension Protection Act of 2006. The Company contributed $10.0 million and $2.5 million to its U.S. and foreign qualified plans, respectively, in 2022. The Company entered into a settlement agreement with a multi-employer pension plan in December of 2019 and, pursuant to that agreement, made a $6.0 million cash payment in 2020, and $5.0 million cash payment in 2021, according to the terms of that settlement agreement.

On March 12, 2021, the Company, as borrower, and its subsidiaries Hubbell Power Holdings S.à r.l. and Harvey Hubbell Holdings S.à r.l., each as a subsidiary borrower (collectively, the “Subsidiary Borrowers”), entered into a new five-year credit agreement with a syndicate of lenders and JPMorgan Chase, N.A., as administrative agent, that provides a $750 million committed revolving credit facility (the "2021 Credit Facility"). Commitments under the 2021 Credit Facility may be increased to an aggregate amount not to exceed $1.25 billion. The 2021 Credit Facility includes a $50 million sub-limit for the issuance of letters of credit. The sum of the dollar amount of loans and letters of credits to the Subsidiary Borrowers under the 2021 Credit Facility may not exceed $75 million. The interest rate applicable to borrowings under the 2021 Credit Facility is either (i) the alternate base rate (as defined in the Revolving Credit Agreement) or (ii) the adjusted LIBOR rate (as defined in the 2021 Credit Facility) plus, in the case of this clause (ii), an applicable margin based on the Company’s credit ratings. All revolving loans outstanding under the 2021 Credit Facility will be due and payable on March 12, 2026. The 2021 Credit Facility contains a financial covenant requiring that, as of the last day of each fiscal quarter, the ratio of total indebtedness to total capitalization shall not be greater than 65%. The Company was in compliance with this covenant as of December 31, 2022. As of December 31, 2022 and December 31, 2021, the 2021 Credit Facility was undrawn. In connection with entry into the 2021 Credit Facility, the Company terminated all commitments under the existing credit facility dated as of January 31, 2018. On March 12, 2021, the Company completed a public offering of $300 million aggregate principal amount of its 2.300% Senior Notes due 2031 (the “2031 Notes”). The net proceeds from the offering were approximately $295.5 million after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company used the net proceeds from the offering of the 2031 Notes, together with cash on hand, to redeem in full all of the Company’s outstanding 3.625% Senior Notes due 2022 in an aggregate principal amount of $300 million, which had a stated maturity date of November 15, 2022 (the “2022 Notes”), and to pay any premium and accrued interest in respect thereof, which redemption was completed on April 2, 2021. The redemption resulted in a $16.8 million loss on extinguishment of indebtedness that was recognized in the second quarter of 2021. The loss on extinguishment includes a cash premium of $16.0 million paid upon redemption in accordance with the terms of the 2022 Notes. The 2031 Notes bear interest at a rate of 2.300% per annum from March 12, 2021. Interest on the 2031 Notes is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2031 Notes will mature on March 15, 2031. The 2031 Notes are callable at any time with a make whole premium and are only subject to accelerated payment prior to maturity in the event of a default (including as a result of the Company's failure to meet certain non-financial covenants) under the indenture governing the notes or upon a change in control triggering event as defined in such indenture. The Company was in compliance with all non-financial covenants as of December 31, 2022.

As of December 31, 2022, $1.9 million of the tax credits may be carried forward indefinitely while the remaining $20.9 million will begin to expire at various times in 2023 through 2051. As of December 31, 2022, the Company had recorded tax benefits totaling $14.0 million for U.S. federal, state and foreign net operating loss carryforwards (“NOLs”). As of December 31, 2022, $5.5 million of NOLs may be carried forward indefinitely while the remaining $8.5 million will begin to expire at various times in 2023 through 2052. The tax benefit related to a portion of these NOLs has been adjusted to reflect an “ownership change” pursuant to Internal Revenue Code Section 382, which imposes an annual limitation on the utilization of pre-acquisition operating losses. The Company has recorded a net valuation allowance of $32.2 million on certain deferred tax assets including a portion of foreign and state tax credit carryforwards, capital loss carryforwards and NOLs that the Company anticipates will expire prior to utilization. During 2022, the Company repatriated certain of its foreign earnings. As of December 31, 2022, the Company also anticipates repatriating certain of its foreign earnings in the future. The accompanying financial statements reflect the income tax expense associated with actual and anticipated remittances related to certain of our outside basis differences. The Company has not provided for the income tax effects of distributing the remaining approximately $400 million of undistributed foreign earnings as those amounts are either permanently reinvested or intended to be reinvested in our international operations. It is not practicable to estimate the tax cost associated with a remittance of such earnings. Cash payments of income taxes were $168.0 million, $84.0 million and $96.2 million in 2022, 2021, and 2020, respectively. The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely audit the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. In January 2023 the Company completed its 2018 U.S. federal tax examination with no material adjustments. With few exceptions, the Company is no longer subject to state, local, or income tax examinations by tax authorities for years prior to 2018. The following tax years, by major jurisdiction, are still subject to examination by taxing authorities: Jurisdiction Open Years United States 2019-2022 UK 2021-2022 Puerto Rico 2018-2022 Canada 2018-2022 A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions): 2022 2021 2020 Unrecognized tax benefits at beginning of year $ 41.2 $ 47.6 $ 41.9 Additions based on tax positions relating to the current year 12.1 6.1 7.4 Reductions based on expiration of statute of limitations (4.8) (10.3) (6.2) Additions/(Subtractions) to tax positions relating to previous years (6.2) (2.2) 4.5 Settlements (0.2) — — TOTAL UNRECOGNIZED TAX BENEFITS $ 42.1 $ 41.2 $ 47.6 Included in the balance at December 31, 2022 are approximately $33.9 million of tax positions which, if in the future are determined to be recognizable, would affect the annual effective income tax rate. Additionally, there are $4.3 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty as to the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate but would accelerate the payment of cash to the applicable taxing authority to an earlier period. It is reasonably possible that in the next twelve months, because of changes in facts and circumstances, the unrecognized tax benefits may increase or decrease. The Company estimates a possible decrease of approximately $5 million to $11 million within the next twelve months due to the expiration of the statute of limitations and audit resolutions. The Company’s policy is to record interest and penalties associated with the underpayment of income taxes within Provision for income taxes in the Consolidated Statement of Income. The Company recognized (benefit) expense, before federal tax impact, related to interest and penalties of $(1.0) million in 2022, $0.3 million in 2021 and $0.2 million in 2020. The Company had $6.7 million and $7.6 million accrued for the payment of interest and penalties as of December 31, 2022 and December 31, 2021, respectively. The consolidated effective income tax rate varied from the United States federal statutory income tax rate of continuing operations for the years ended December 31, as follows: 2022 2021 2020 Federal statutory income tax rate 21.0 % 21.0 % 21.0 % State income taxes, net of federal benefit 2.4 2.5 2.9 Foreign income taxes (0.2) (0.5) (0.2) Federal R&D Credit (0.8) (1.4) (1.3) Other, net (1.1) (2.4) (1.2) CONSOLIDATED EFFECTIVE INCOME TAX RATE 21.3 % 19.2 % 21.2 %

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurement	Financial Instruments and Fair Value Measurement Financial Instruments Concentrations of Credit Risk: Financial instruments which potentially subject the Company to significant concentrations of credit 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. We are not dependent on a single customer, however, the Company’s top ten customers account for approximately 43% of its Net sales. 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 December 31, 2022 our accounts receivable balance was $741.6 million, net of allowances of $14.3 million. The allowance for doubtful accounts has not materially changed since December 31, 2021. Fair Value: The carrying amounts reported in the Consolidated Balance Sheet for cash and cash equivalents, short-term investments, receivables, bank borrowings, accounts payable and accruals approximate their fair values given the immediate or short-term nature of these items. See also Note 8 — Investments. Fair value measurements At December 31, 2022 and 2021 the Company had $80.2 million and $78.5 million respectively, of investments carried on the balance sheet at fair value. 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. Refer to Note 8 — Investments for more information about these investments. 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 tables show, by level within the fair value hierarchy, the Company’s financial assets and liabilities that are accounted for at fair value on a recurring basis at December 31, 2022 and 2021 (in millions): Asset (Liability) Quoted Prices in Active Markets for Identical Assets (Level 1) Quoted Prices in Active Markets for Similar Assets (Level 2) Unobservable inputs for which little or no market data exists (Level 3) Total Money market funds (a) $ 147.9 $ — $ — $ 147.9 Time Deposits (a) — 4.8 — 4.8 Available for sale investments — 61.4 — 61.4 Trading securities 18.8 — — 18.8 Deferred compensation plan liabilities (18.8) — — (18.8) Derivatives: Forward exchange contracts-Assets (b) — 1.1 — 1.1 BALANCE AT DECEMBER 31, 2022 $ 147.9 $ 67.3 $ — $ 215.2 Asset (Liability) Quoted Prices in Active Markets for Identical Assets (Level 1) Quoted Prices in Active Markets for Similar Assets (Level 2) Unobservable inputs for which little or no market data exists (Level 3) Total 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 BALANCE AT DECEMBER 31, 2021 $ 58.5 $ 54.5 $ — $ 113.0 (a) Money market funds and time deposits are included in Cash and cash equivalents in the Consolidated Balance Sheet. (b) Forward exchange contracts-Assets are reflected in Other current assets in the Consolidated Balance Sheet. 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 were 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 plan 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. During 2022 and 2021, the Company purchased $2.2 million and $2.7 million, respectively, of trading securities related to these deferred compensation plans. As a result of participant distributions, the Company sold $4.2 million and $3.6 million of these trading securities in 2022 and 2021 respectively. 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 December 31, 2022 and December 31, 2021, the carrying value of long-term debt, net of unamortized discount and debt issuance costs, was $1,437.9 million and $1,435.5 million, respectively. The estimated fair value of the long-term debt as of December 31, 2022 and December 31, 2021 was $1,306.5 million and $1,524.5 million, respectively, using quoted market prices in active markets for similar liabilities (Level 2) .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal and Environmental The Company is subject to various legal proceedings arising in the normal course of its business. These proceedings include claims for damages arising out of use of the Company’s products, intellectual property, workers’ compensation and environmental matters. The Company is self-insured up to specified limits for certain types of claims, including product liability and workers’ compensation, and is fully self-insured for certain other types of claims, including environmental and intellectual property matters. The Company recognizes a liability for any contingency that in management’s judgment is probable of occurrence and can be reasonably estimated. We continually reassess the likelihood of adverse judgments and outcomes in these matters, as well as estimated ranges of possible losses based upon an analysis of each matter which includes advice of outside legal counsel and, if applicable, other experts. The Company is subject to environmental laws and regulations which may require that it investigate and remediate the effects of potential contamination associated with past and present operations as well as those acquired through business combinations. Environmental liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. The Company continues to monitor these environmental matters and revalues its liabilities as necessary. Total environmental liabilities The Company accounts for conditional asset retirement and environmental obligations in accordance with the applicable accounting guidance. The accounting guidance defines “conditional asset retirement obligation” as a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. Asset retirement obligations were not material as of December 31, 2022 and 2021.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation As of December 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 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. In 2022, the Company's grant of stock-based awards included restricted stock, SARs and performance shares. Stock-based compensation expense recognized by the Company was $24.5 million in 2022, $17.5 million in 2021 and $21.9 million in 2020. The total income tax benefit recognized was $3.9 million in 2022, $3.2 million in 2021, and $3.2 million in 2020. The net tax windfall recorded as a result of exercise or vesting (depending on the type of award) was $3.2 million, $6.8 million, and $3.4 million in 2022, 2021 and 2020, respectively. As of December 31, 2022, there was $18.1 million, pretax, of total unrecognized compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be primarily recognized through 2025. Stock-based compensation expense is recorded in S&A expense as well as Cost of goods sold. Of the total 2022 expense, $23.2 million was recorded to S&A expense and $1.3 million was recorded to Cost of goods sold. In 2021 and 2020, $15.8 million and $20.4 million, respectively, was recorded to S&A expense and $1.7 million and $1.5 million, respectively, was recorded to Cost of goods sold. Stock-based compensation costs capitalized to inventory was $0.4 million in each of 2022, 2021 and 2020. 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”). Restricted Stock Issued to Non-employee Directors In 2022, 2021 and 2020, each non-employee director received a restricted stock grant. These grants are made on the date of the annual meeting of shareholders and vest at the following year’s annual meeting of shareholders, or upon certain other events. The grant is subject to forfeiture if the director’s service terminates prior to the date of the next regularly scheduled annual meeting of shareholders. During 2022, 2021 and 2020, the Company granted 5,952 shares, 6,741 shares, and 7,413 shares, respectively, to non-employee directors. Restricted Stock Issued to Employees and Non-employee Directors Activity related to both employee and non-employee restricted stock for the year ended December 31, 2022 is as follows (in thousands, except per share amounts): Shares Weighted Average Grant Date Fair Value/Share RESTRICTED STOCK AT DECEMBER 31, 2021 184 $ 141.99 Shares granted 64 187.07 Shares vested (56) 148.93 Shares forfeited (13) 163.54 RESTRICTED STOCK AT DECEMBER 31, 2022 179 $ 154.09 The weighted average fair value per share of restricted stock granted in 2022, 2021 and 2020 was $187.07, $166.46 and $145.48, respectively. The total fair value of restricted stock vested in 2022, 2021 and 2020 was $8.4 million, $12.6 million and $7.8 million, respectively. 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. Activity related to SARs for the year ended December 31, 2022 is as follows (in thousands, except per share amounts): Number of Rights Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value OUTSTANDING AT DECEMBER 31, 2021 907 $ 132.78 Granted 143 186.62 Exercised (245) 122.49 Forfeited (26) 170.12 Canceled — — OUTSTANDING AT DECEMBER 31, 2022 779 $ 144.66 6.8 years $ 70,146 EXERCISABLE AT DECEMBER 31, 2022 452 $ 127.44 5.7 years $ 48,506 The aggregated intrinsic value of SARs exercised during 2022, 2021 and 2020 was $21.0 million, $46.8 million and $20.2 million, respectively. 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 years 2022, 2021 and 2020: Grant Date Expected Dividend Yield Expected Volatility Risk Free Interest Rate Expected Term Weighted Avg. Grant Date Fair Value of 1 SAR 2022 2.1 % 27.4 % 1.9 % 4.9 years $ 39.68 2021 2.4 % 26.5 % 0.6 % 5.5 years $ 29.58 2020 2.5 % 23.5 % 1.3 % 5.5 years $ 24.52 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 - Performance and Market Conditions In February 2020 and December 2018, the Company granted performance share awards with a target payout of 63,868 and 60,008 shares, respectively, that will vest subject to a performance condition and service requirement. The number of shares vested is then modified by a market condition as described below. Thirty-four percent of the award 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. Thirty-three percent of the award granted will vest based on achieved operating margin performance as compared to internal targets, and thirty-three percent of the award granted will vest based on achieved trade working capital as a percent of Net sales 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 subject to the award. That cumulative performance achieved is then further modified based on the Company's three year TSR relative to the companies that constitute the S&P Capital Goods 900 index, to potentially increase or reduce the shares earned by a multiple of up to 1.5 or 1.2, depending on the award year. The fair value of the award was determined based upon a lattice model. The Company expenses these awards on a straight-line basis over the requisite service period which includes an assessment of the performance achieved to date. The weighted average fair value per share was $151.78 for the awards granted in 2020 and $98.80 for the awards granted in 2018. Grant Date Shares Outstanding at 12/31/2022 Fair Value Performance Period Payout Range 2020 43,949 $ 151.78 Jan 2020-Dec 2022 0-200% + up to a multiple of 150x 2018 — $ 98.80 Jan 2019-Dec 2021 0-200% + up to a multiple of 120x During 2022, approximately 38,000 shares from the 2018 awards vested as a result of the cumulative achievement of the performance metrics, and the fair value of the awards at vesting was approximately $7.3 million. Performance Shares - Market Condition In February 2022 and 2021, the Company granted performance share awards with a target payout of 14,076 and 15,741 shares, respectively, 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 period. Performance at target will result in vesting and issuance of the number of performance shares subject to the award, equal to 100% payout. Performance below or above target can result in issuance in the range of 0%-200% of the number of shares subject to the award. Expense is recognized irrespective of the market condition being achieved. The fair value of the performance share awards with a market condition for these grants 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 and 2021: 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 February 2021 $163.26 2.4% 40.6% 0.2% 3 years $198.89 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 and 2021, the Company granted performance share awards with a target payout of 28,628 and 31,543 shares, respectively, that will vest subject to an internal Company-based performance condition and service requirement. Fifty percent of these performance shares subject to the award 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 subject to the award 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 subject to the award. 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 and $151.92 for the awards granted in 2022 and 2021, respectively. Grant Date Fair Value Performance Period Payout Range February 2022 $174.48 Jan 2022 - Dec 2024 0-200% February 2021 $151.92 Jan 2021 - Dec 2023 0-200%

Standard Product Warranty Disclosure [Abstract]
Guarantees	Guarantees The Company records a liability equal to the fair value of guarantees in the Consolidated Balance Sheet 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 December 31, 2022, the fair value and maximum potential payment related to the Company’s guarantees were not material. The Company offers product warranties which 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 in 2022 are set forth below (in millions): BALANCE AT DECEMBER 31, 2020 $ 72.7 Provision 8.8 Expenditures/other (15.4) BALANCE AT DECEMBER 31, 2021 $ 66.1 Provision 12.7 Expenditures/other (32.6) BALANCE AT DECEMBER 31, 2022 (a) $ 46.2 (a) Refer to Note 10 – Other Accrued Liabilities and Note 11 – Other Non-Current Liabilities for a breakout of short-term and long-term warranties.

Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs During 2022, we incurred costs for restructuring actions initiated in 2022 as well as costs relating to restructuring actions initiated in the prior year. Our restructuring actions are associated with cost reduction efforts that include the consolidation of manufacturing and distribution facilities, as well as, workforce reductions and the sale or exit of business units we determine to be non-strategic. Restructuring costs are primarily severance and employee benefits, asset impairments, as well as facility closure, contract termination and certain pension costs that are directly related to restructuring actions. These costs are predominantly settled in cash from our operating activities and are generally settled within one year, with the exception of asset impairments, which are non-cash. Pre-tax restructuring costs incurred in each of our segments and the location of the costs in the Consolidated Statement of Income for the years ended December 31, 2022, 2021 and 2020 are as follows (in millions): Twelve Months Ended December 31, 2022 Twelve Months Ended December 31, 2021 Twelve Months Ended December 31, 2020 Utility Solutions Electrical Solutions Total Utility Solutions Electrical Solutions Total Utility Solutions Electrical Solutions Total Restructuring costs Cost of goods sold $ 4.5 $ 5.4 $ 9.9 $ 1.3 $ 1.1 $ 2.4 $ 9.2 $ 7.1 $ 16.3 S&A expense (0.5) 0.9 0.4 1.1 0.4 1.5 1.2 2.9 4.1 Total restructuring costs $ 4.0 $ 6.3 $ 10.3 $ 2.4 $ 1.5 $ 3.9 $ 10.4 $ 10.0 $ 20.4 The following table summarizes the accrued liabilities for our restructuring actions (in millions): Beginning Accrued Pre-tax Restructuring Costs Utilization and Ending Accrued 2022 Restructuring Actions Severance $ — $ 6.9 $ (1.3) $ 5.6 Asset write-downs — 0.8 (0.8) — Facility closure and other costs — 3.5 (3.2) 0.3 Total 2022 Restructuring Actions $ — $ 11.2 $ (5.3) $ 5.9 2021 and Prior Restructuring Actions Severance $ 4.1 $ (0.4) $ (1.8) $ 1.9 Asset write-downs — — — — Facility closure and other costs 0.1 (0.5) 0.5 0.1 Total 2021 and Prior Restructuring Actions $ 4.2 $ (0.9) $ (1.3) $ 2.0 Total Restructuring Actions $ 4.2 $ 10.3 $ (6.6) $ 7.9 The actual and expected pre-tax costs for our restructuring actions are as follows (in millions): Expected Costs Costs incurred in 2020 Costs incurred in 2021 Costs incurred in 2022 Remaining costs at 12/31/22 2022 Restructuring Actions Utility Solutions $ 5.0 $ — $ — $ 4.7 $ 0.3 Electrical Solutions 10.2 — — 6.5 3.7 Total 2022 Restructuring Actions $ 15.2 $ — $ — $ 11.2 $ 4.0 2021 Restructuring Actions Utility Solutions $ 3.7 $ — $ 1.8 $ (0.7) $ 2.6 Electrical Solutions 0.4 — 0.6 (0.2) — Total 2021 Restructuring Actions $ 4.1 $ — $ 2.4 $ (0.9) $ 2.6 2020 and Prior Restructuring Actions Utility Solutions $ 11.0 $ 10.4 $ 0.6 $ — $ — Electrical Solutions 10.9 10.0 0.9 — — Total 2020 and Prior Restructuring Actions $ 21.9 $ 20.4 $ 1.5 $ — $ — Total Restructuring Actions $ 41.2 $ 20.4 $ 3.9 $ 10.3 $ 6.6

The qualitative analysis is based on identifying the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance (the “power criterion”) and the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE (the “losses/benefit criterion”). The party that meets both these criteria is deemed to have a controlling financial interest. The party with the controlling financial interest is considered to be the primary beneficiary and as a result is required to consolidate the VIE. The Company has a 50% interest in a joint venture in Hong Kong, established as Hubbell Asia Limited (“HAL”). The principal objective of HAL is to manage the operations of its wholly-owned manufacturing company in China. Under the accounting guidance, the Company is the primary beneficiary of HAL and as a result consolidates HAL.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could differ from the estimates that are used.
Impact of the COVID-19 Pandemic	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.
Assets and Liabilities Held for Sale	Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
Revenue Recognition	Revenue Recognition 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 in the Utility Solutions segment recognized upon delivery of the product at the contractually specified destination. Revenue from service contracts and post-shipment performance obligations is 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 Consolidated Balance Sheet. Once control transfers to the customer and the Company meets the revenue recognition criteria, the deferred revenue is recognized in the Consolidated Statement of Income. The deferred revenue relating to the annual maintenance service contracts is recognized in the Consolidated Statement of Income on a straight line basis over the expected term of the contract. The Company has certain arrangements that require us to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of the product to be returned. The Company principally relies on historical experience, specific customer agreements and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include sales discounts and allowances based on sales volumes, specific programs and special pricing allowances, and returned goods, as are customary in the electrical products industry. Customer returns have historically been approximately 1% of gross sales. Shipping and Handling Costs
Foreign Currency Translation	Foreign Currency Translation The assets and liabilities of international subsidiaries are translated to U.S. dollars at exchange rates in effect at the end of the year, and income and expense items are translated at average exchange rates in effect during the year. The effects of exchange rate fluctuations on the translated amounts of foreign currency assets and liabilities are included as translation adjustments in Accumulated other comprehensive loss within Hubbell shareholders’ equity. Gains and losses from foreign currency transactions are included in results of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents The carrying value of cash equivalents approximates fair value. Cash equivalents consist of highly liquid investments with original maturities to the Company of three months or less.
Investments	Investments
Accounts Receivable and Allowances	Accounts Receivable and Allowances Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is based on an estimated amount of probable credit losses in existing accounts receivable. The allowance is calculated based upon a combination of historical write-off experience, fixed percentages applied to aging categories and specific identification based upon a review of past due balances and problem accounts. Account balances are charged off against the allowance when it is determined that internal collection efforts should no longer be pursued. The Company also maintains a reserve for credit memos and cash discounts which are principally calculated based upon historical experience, specific customer agreements, as well as anticipated future trends.
Inventories	Inventories Inventories are stated at the lower of cost or market value. Approximately 60% of total net inventory value is determined utilizing the last-in, first-out (LIFO) method of inventory accounting. The cost of foreign inventories and certain domestic inventories is determined utilizing average cost or first-in, first-out (FIFO) methods of inventory accounting. Reserves for excess and obsolete inventory are provided based on current assessments about future demand compared to on-hand quantities.
Property, Plant and Equipment	Property, Plant, and Equipment Property, plant, and equipment values are stated at cost less accumulated depreciation. Maintenance and repair expenditures that do not significantly increase the life of an asset are charged to expense when incurred. Property, plant, and equipment placed in service prior to January 1, 1999 are depreciated over their estimated useful lives, principally, using accelerated methods. Assets placed in service subsequent to January 1, 1999 are depreciated over their estimated useful lives, using straight-line methods. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Gains and losses arising on the disposal of property, plant and equipment are included in Operating income in the Consolidated Statement of Income.
Capitalized Computer Software Costs	Capitalized Computer Software Costs Capitalized computer software costs, net of amortization, were $7.0 million and $10.8 million at December 31, 2022 and 2021, respectively. This balance is reflected in Other long-term assets in the Consolidated Balance Sheet. Capitalized computer software is for internal use and costs primarily consist of purchased materials, external services and salary costs for personnel dedicated to the projects. Software is amortized on a straight-line basis over appropriate periods, generally between three
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents purchase price in excess of fair values of the underlying net assets of acquired companies. Indefinite-lived intangible assets and goodwill are subject to annual impairment testing using the specific guidance and criteria described in the accounting guidance. The Company performs its goodwill impairment testing as of April 1st of each year, unless circumstances dictate the need for more frequent assessments. The accounting guidance provides entities an option of performing a qualitative assessment (a "step-zero" test) before performing a quantitative analysis. If the entity determines, on the basis of certain qualitative factors, that it is more-likely-than-not that the goodwill is not impaired, the entity would not need to proceed to quantitative goodwill impairment testing process as prescribed in the guidance. The Company applied the "step-zero" test to one of its four reporting units. Based on that qualitative assessment, the Company concluded it was more-likely-than-not that the fair value of this reporting unit exceeded its carrying value and therefore, further quantitative analysis was not required. For the other three reporting units the Company has elected to utilize the quantitative goodwill impairment testing process as permitted in the accounting guidance, by comparing the estimated fair value of the Company's reporting units to their carrying values. If the fair value of the 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 judgments required to estimate the fair value of reporting units include estimating future discounted 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, impacts to the supply chain and higher inflation. We use 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 on future sales growth, gross margin, operating margin, terminal growth rate, and the application of an appropriate discount rate. 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. 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. 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. As of April 1, 2022, the impairment testing resulted in implied fair values of our reporting units that exceeded the reporting unit's carrying value, including goodwill. The range of fair value in excess of carrying value, including goodwill, of the reporting units was 57% to 308%. Additionally, the Company did not have any reporting units with zero or negative carrying amounts. The Company has not recorded any goodwill impairments since the initial adoption of the accounting guidance in 2002. The Company’s intangible assets consist primarily of customer relationships, tradenames, developed technology and patents. Intangible assets with definite lives are amortized over periods generally ranging from 5-30 years. 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. These definite lived intangibles are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The Company did not record any material impairments related to its definite lived intangible assets in 2022, 2021 or 2020. The Company also has some tradenames that are considered to be indefinite-lived intangible assets. These indefinite-lived intangible assets are not amortized and are tested for impairment annually, unless circumstances dictate the need for more frequent assessment. The identification and measurement of impairment of indefinite-lived intangible assets involves either an assessment of qualitative factors to determine whether events or circumstances indicate that it is more-likely-than-not that an indefinite-lived intangible asset is impaired or a quantitative assessment whereby the estimated fair value of each indefinite-lived intangible asset is compared to its carrying value. If it is more-likely-than-not that the asset is impaired, the fair value of the indefinite lived intangibles will be determined using discounted cash flow estimates. If the carrying value of these assets exceeds the estimated fair value, the carrying value will be reduced to the estimated fair value. For the Company’s annual impairment test as of April 1, 2022, the Company elected to utilize the quantitative impairment testing process as permitted in the accounting guidance. The fair value was determined utilizing an income approach (relief from royalty method). Significant judgment is required to estimate the fair value of the indefinite-lived intangible assets including assumptions for future revenues,
Other Long-Lived Assets	Other Long-Lived Assets The Company reviews depreciable long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If such a change in circumstances occurs, the related estimated future undiscounted cash flows expected to result from the use of the asset group and its eventual disposition is compared to the carrying amount. If the sum of the expected cash flows is less than the carrying amount, an impairment charge is recorded. The impairment charge is measured as the amount by which the carrying amount exceeds the fair value of the asset. The fair value of impaired assets is determined using expected cash flow estimates, quoted market prices when available and appraisals as appropriate. The Company did not record any material impairment charges in 2022, 2021 or 2020.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included as ROU assets within other long-term assets, other accrued liabilities, and other non-current liabilities in our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other accrued liabilities, and other non-current liabilities. The Company's finance leases are immaterial. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use an implicit rate when readily determinable. For leases existing as of January 1, 2019, we have elected to use the remaining lease term as of the adoption date in determining the incremental borrowing rate. Our determination of the lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Additionally, for our vehicle leases, we apply a portfolio approach regarding the assumed lease term.
Accrued Insurance	Accrued Insurance The Company retains a significant portion of the risks associated with workers’ compensation, medical, automobile and general liability insurance. The Company estimates self-insurance liabilities using a number of factors, including historical claims experience, demographic factors, and other actuarial assumptions. The accrued liabilities associated with these programs are based on the Company’s estimate of the ultimate costs to settle known claims as well as claims incurred but not reported as of the balance sheet date. The Company periodically reviews the assumptions with a third party actuary to determine the adequacy of these self-insurance reserves.
Accrued Warranty	Accrued Warranty The Company offers product warranties which 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.
Income Taxes	Income Taxes The Company operates within multiple taxing jurisdictions and is subject to audit in these jurisdictions. The IRS and other tax authorities routinely examine the Company’s tax returns. These audits can involve complex issues which may require an extended period of time to resolve. The Company makes adequate provisions for best estimates of exposures on previously filed tax returns. Deferred income taxes are recognized for the tax consequence of differences between financial statement carrying amounts and the tax basis of assets and liabilities by applying the currently enacted statutory tax rates in accordance with the accounting guidance for income taxes. The effect of a change in statutory tax rates is recognized in the period that includes the enactment date. Additionally, deferred tax assets are required to be reduced by a valuation allowance if it is more-likely-than-not that a portion or all of the deferred tax asset will not be realized. The Company uses factors to assess the likelihood of realization of deferred tax assets such as the forecast of future taxable income and available tax planning that could be implemented to realize the deferred tax assets.
Research and Development	Research and Development
Government Assistance	Government Assistance We have adopted Accounting Standards Update ("ASU") 2021-10, Government Assistance (Topic 832) Disclosures by Business Entities about Government Assistance, which requires footnote disclosure of assistance received from government entities. We record amounts received from government entities as a reduction of the associated expense. Amounts received related to depreciable assets are recognized as a reduction to depreciation expense. The total impact of government assistance was not material to the Company in 2022, and prior periods presented.
Retirement Benefits	Retirement Benefits The Company maintains various defined benefit pension plans for some of its U.S. and foreign employees. The accounting guidance for retirement benefits requires the Company to recognize the funded status of its defined benefit pension and postretirement plans as an asset or liability in the Consolidated Balance Sheet. Gains or losses, prior service costs or credits, and transition assets or obligations that have not yet been included in net periodic benefit cost as of the end of the year are recognized as components of Accumulated other comprehensive loss, net of tax, within Hubbell shareholders’ equity. The Company’s policy is to fund pension costs within the ranges prescribed by applicable regulations. In addition to providing defined benefit pension benefits, the Company provides health care and life insurance benefits for some of its active and retired employees. The Company’s policy is to fund these benefits through insurance premiums or as actual expenditures are made. See also Note 12 — Retirement Benefits.
Earnings Per Share	Earnings Per Share Restricted stock granted by the Company is considered a participating security since it contains a non-forfeitable right to dividends. As a result, the earnings per share accounting guidance requires the Company to use the two-class method for calculating earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for common stock and participating securities. Basic earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares of common stock outstanding. Earnings per diluted share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding of common stock plus the incremental shares outstanding assuming the exercise of dilutive stock options, stock appreciation rights and performance shares. See also Note 19 — Earnings Per Share.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes the grant-date fair value of all stock-based awards on a straight-line basis over their respective requisite service periods (generally equal to an award’s vesting period). A stock-based award is considered vested for expense attribution purposes when the retention of the award is no longer contingent on providing subsequent service. Accordingly, the Company generally recognizes compensation cost immediately for awards granted to 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 expense is recorded in Cost of goods sold and S&A expense in the Consolidated Statement of Income based on the recipients’ respective functions within the organization. The Company records deferred tax assets for awards that will result in deductions on its tax returns, based upon the amount of compensation cost recognized and the statutory tax rate in the jurisdiction in which it will receive a deduction. See also Note 18 — Stock-Based Compensation.
Recent 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. In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the temporary accounting rules under Topic 848 to December 31, 2024. The Company is currently assessing the impact of adopting this standard on its financial statements and the timing of adoption.
