Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Hubbell Incorporated (“Hubbell”, the “Company”, “registrant”, “we”, “our” or “us”, which references shall include its divisions and subsidiaries) have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S.”) for complete financial statements. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. Operating results for the nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 . The balance sheet at December 31, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. During the fourth quarter of 2015, the Company identified a misclassification of costs between Cost of goods sold and Selling & administrative expenses that occurred during the first, second and third quarters of 2015, which has resulted in management revising its previously reported financial results to correct for such misclassification. The impact of the misclassification was to overstate Selling & administrative expenses and understate Cost of goods sold by $1.1 million for the three months ended September 30, 2015 . Accordingly, the originally reported Cost of goods sold of $585.9 million , the originally reported Gross profit of $291.1 million and the originally reported Selling & administrative expenses of $160.1 million for the three months ended September 30, 2015 were revised by $1.1 million in the accompanying Condensed Consolidated Statement of Income. In addition, the impact of the misclassification was to overstate Selling & administrative expenses and understate Cost of goods sold by $3.0 million for the nine months ended September 30, 2015 . Accordingly, the originally reported Cost of goods sold of $1,732.8 million , the originally reported Gross profit of $827.9 million , and the originally reported Selling & administrative expenses of $465.2 million for the nine months ended September 30, 2015 were revised by $3.0 million in the accompanying Condensed Consolidated Statement of Income. Management has concluded that the misclassifications are immaterial to the previously issued quarterly financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Hubbell Incorporated Annual Report on Form 10-K for the year ended December 31, 2015 . Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update (ASU 2016-09) relating to the accounting for share-based payments. Upon adoption, from a statement of income viewpoint, the new guidance will require all income tax effects of share-based awards to be recognized in the income statement when the awards vest or are settled, and allows companies an additional election in the methods to estimate forfeitures of share-based payments. It also increases the amount an employer can withhold to satisfy the employer's statutory income tax withholding obligation while still qualifying for the exception to liability classification of the share-based awards. From a statement of cash flows viewpoint, the new guidance requires that excess tax benefits be classified as an operating activity and cash paid to a tax authority when shares are withheld to satisfy the employer's statutory income tax withholdings be classified as a financing activity. This update is effective for fiscal years beginning after December 15, 2016 with early adoption permitted. The Company is currently assessing the impact of this standard on its financial statements. In February 2016, the FASB issued an Accounting Standards Update (ASU 2016-02) related to the accounting for leases. This guidance will require a lessee to recognize a right-to-use asset and a lease liability for both financing and operating leases, with the option of a policy election permitting an exception to this guidance for leases whose term is twelve months or less. For finance leases, the lessee will recognize interest expense and amortization of the right-of-use asset, and for operating leases the lessee will recognize a straight-line lease expense. This guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The new standard must be adopted using a modified retrospective transition at the beginning of the earliest comparative period presented. The Company is currently assessing the impact of adopting this standard on its financial statements. In May 2014, the FASB issued an Accounting Standards Update (ASU 2014-09) related to new revenue recognition guidance that supersedes the existing revenue recognition guidance and most industry-specific guidance applicable to revenue recognition. According to the new guidance an entity will apply a principles-based five step model to recognize revenue upon the transfer of promised goods or services to customers and in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for fiscal years beginning after December 15, 2017 with earlier application permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. This standard can be applied on either a retrospective or modified retrospective approach. Through the course of 2016 a number of ASU's have been issued which further refine the original guidance issued under ASU 2014-09 and are effective in conjunction with this original standard. The Company is currently assessing the impact of adopting these standards on its financial statements.

Business Acquisitions	Sep. 30, 2016
Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions In the first quarter of 2016, the Company acquired all of the outstanding shares of R.W. Lyall & Company, Inc. ("Lyall"), a leader in the design and application of components and assemblies for the natural gas distribution market. Lyall was purchased for $129.1 million , net of cash received, and has been added to the Electrical segment, resulting in the recognition of intangible assets of $68.9 million and goodwill of $48.4 million . The $68.9 million of intangible assets consists primarily of customer relationships and trade names and will be amortized over a weighted average period of approximately 21 years. All of the goodwill is expected to be deductible for tax purposes. In the first quarter of 2016, the Company acquired all of the issued and outstanding shares of Electric Motion Company, Inc. and all of the membership interests in Elmot Realty Associates, LLC, Elmot Realty Associates II, LLC, and DelRi LLC, collectively referred to as "EMC". EMC is a leading manufacturer of grounding and connector products for the communications, power, and transportation industries and was purchased for $42.5 million , net of cash received, and has been added to the Power segment, resulting in the recognition of intangible assets of $16.9 million and goodwill of $16.4 million . The $16.9 million of intangible assets consists primarily of customer relationships and trade names and will be amortized over a weighted average period of approximately 19 years. None of the goodwill associated with the EMC acquisition is expected to be deductible for tax purposes. In the third quarter of 2016, the Company acquired all of the equity interests of Jiangsu Xiang Yuan Electric Equipment Co., Ltd. ("Longbow"). Longbow is a leading manufacturer of high voltage polymer insulators for the electric utility and railway industry. Longbow was purchased for approximately $14.2 million , net of $2.0 million cash received, of which $2.9 million was paid at closing, and the remaining approximately $13.3 million is to be paid in future installments. The purchase price is subject to customary post-closing adjustments. Longbow has been added to the Power segment. We have recognized intangible assets of $6.8 million and goodwill of $2.0 million as a result of this acquisition. The $6.8 million of intangible assets consists primarily of customer relationships and trade names and will be amortized over a weighted average period of approximately 11 years. None of the goodwill associated with the Longbow 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 built into the purchase price, including the future earnings and cash flow potential of the businesses as well as the complementary strategic fit and resulting synergies they bring to the Company’s existing operations. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of acquisition related to these transactions (in millions): Tangible assets acquired $ 66.2 Intangible assets 92.6 Goodwill 66.9 Net deferred taxes (8.7 ) Other liabilities assumed (31.2 ) TOTAL CONSIDERATION, NET OF CASH RECEIVED $ 185.8 The allocation of purchase price is based on preliminary estimates and assumptions, and is subject to revision based on final information received and other analysis that support the underlying estimates. We expect to complete our purchase accounting within the measurement period for each acquisition. The Condensed Consolidated Financial Statements include the results of operations of the acquired entities from the date of acquisition. Net sales and earnings related to these acquisitions for the three and nine months ended September 30, 2016 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.

Earnings Per Share	Sep. 30, 2016
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company computes earnings per share using the two-class method, which is an earnings allocation formula that determines earnings per share for common stock and participating securities. Service-based and performance-based restricted stock awards granted by the Company are considered participating securities as these awards contain a non-forfeitable right to dividends. The following table sets forth the computation of earnings per share for the three and nine months ended September 30, 2016 and 2015 (in millions, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Numerator: Net income attributable to Hubbell $ 86.7 $ 73.3 $ 228.6 $ 215.8 Less: Earnings allocated to participating securities (0.3 ) (0.2 ) (0.7 ) (0.6 ) Net income available to common shareholders $ 86.4 $ 73.1 $ 227.9 $ 215.2 Denominator: Average number of common shares outstanding 55.3 57.7 55.6 57.8 Potential dilutive common shares 0.2 0.2 0.2 0.3 Average number of diluted shares outstanding 55.5 57.9 55.8 58.1 Earnings per share: Basic $ 1.56 $ 1.27 $ 4.10 $ 3.73 Diluted $ 1.56 $ 1.27 $ 4.08 $ 3.71 The Company did not have any significant anti-dilutive securities during the three and nine months ended September 30, 2016 and 2015 . The calculation of diluted earnings per share for the three and nine months ended September 30, 2016 excludes 55,561 and 56,147 , respectively, of performance shares that are subject to a performance condition. The calculation of diluted earnings per share for the three and nine months ended September 30, 2015 excludes 27,508 and 28,105 , respectively, of performance shares that are subject to a performance condition. These shares are excluded from the calculation of diluted earnings per share because all necessary performance conditions were not satisfied at the end of those reporting periods.

No contributions were required in the prior year, but the Company made a voluntary contribution to its qualified domestic defined benefit pension plan of $20.0 million in January 2015. The Company anticipates making required contributions of approximately $1.9 million to its foreign pension plans during 2016 , of which $ 1.4 million has been contributed through September 30, 2016 .

Standard Product Warranty Disclosure [Abstract]
Guarantees	Guarantees The Company records a liability equal to the fair value of guarantees in the Condensed 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 September 30, 2016 and December 31, 2015 , the fair value and maximum potential payment related to the Company’s guarantees were not material. The Company offers product defect warranties on most of its products. These warranties primarily apply to products that are properly installed, maintained and used for their intended purpose. The Company accrues estimated warranty costs at the time of sale. Estimated warranty expenses, recorded in cost of goods sold, are based upon historical information such as past experience, product failure rates, or the estimated number of units to be repaired or replaced. Adjustments are made to the product warranty accrual as claims are incurred, additional information becomes known or as historical experience indicates. Changes in the accrual for product warranties during the nine months ended September 30, 2016 and 2015 are set forth below (in millions): 2016 2015 BALANCE AT JANUARY 1, $ 13.2 $ 13.7 Provision 7.0 8.1 Expenditures/other (6.7 ) (8.1 ) BALANCE AT SEPTEMBER 30, $ 13.5 $ 13.7

Fair Value Measurement	Sep. 30, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Investments At September 30, 2016 and December 31, 2015 , the Company had $55.7 million and $52.0 million , respectively, of available-for-sale securities. At September 30, 2016 our available-for-sale securities consisted of $50.8 million of municipal bonds classified in Level 2 of the fair value hierarchy, as well as $4.9 million of redeemable preferred stock classified in Level 3 of the fair value hierarchy. At December 31, 2015 our available-for-sale securities consisted of $47.4 million of municipal bonds classified in Level 2 of the fair value hierarchy, as well as $4.6 million of redeemable preferred stock classified in Level 3 of the fair value hierarchy. The Company also had $10.4 million of trading securities at September 30, 2016 and $9.7 million at December 31, 2015 that are carried on the balance sheet at fair value. Unrealized gains and losses associated with available-for-sale securities are reflected in Accumulated other comprehensive loss, net of tax, while unrealized gains and losses associated with trading securities are reflected in the results of operations. Fair value measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. The three broad levels of the fair value hierarchy are as follows: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions. The following table shows, by level within the fair value hierarchy, our financial assets and liabilities that are accounted for at fair value on a recurring basis at September 30, 2016 and December 31, 2015 (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 September 30, 2016 Money market funds (a) $ 184.4 $ — $ — $ 184.4 Available for sale investments — 50.8 4.9 55.7 Trading securities 10.4 — — 10.4 Deferred compensation plan liabilities (10.4 ) — — (10.4 ) Derivatives: Forward exchange contracts-Assets (b) — 0.2 — 0.2 Forward exchange contracts-(Liabilities) (c) — (0.4 ) — (0.4 ) TOTAL $ 184.4 $ 50.6 $ 4.9 $ 239.9 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 December 31, 2015 Money market funds (a) $ 210.9 $ — $ — $ 210.9 Available for sale investments — 47.4 4.6 52.0 Trading securities 9.7 — — 9.7 Deferred compensation plan liabilities (9.7 ) — — (9.7 ) Derivatives: Forward exchange contracts-Assets (b) — 2.5 — 2.5 Forward exchange contracts-(Liabilities) (c) — (0.1 ) — (0.1 ) TOTAL $ 210.9 $ 49.8 $ 4.6 $ 265.3 (a) Money market funds are reflected in Cash and cash equivalents in the Condensed Consolidated Balance Sheet. (b) Forward exchange contracts-Assets are reflected in Other current assets in the Condensed Consolidated Balance Sheet. (c) Forward exchange contracts-(Liabilities) are reflected in Other accrued liabilities in the Condensed Consolidated Balance Sheet. The methods and assumptions used to estimate the Level 2 and Level 3 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. Available-for-sale redeemable preferred stock classified in Level 3 – The fair value of the available-for-sale investment in redeemable preferred stock is valued based on a discounted cash flow model, using significant unobservable inputs, including expected cash flows and the discount rate. During the three and nine months ended September 30, 2016 there were no transfers of financial assets or liabilities in or out of Level 1 or Level 2 of the fair value hierarchy. There were also no transfers in or out of Level 3 during that period. Deferred compensation plans The Company offers certain employees the opportunity to participate in non-qualified deferred compensation plans. A participant’s deferrals are invested in a variety of participant-directed debt and equity mutual funds that are classified as trading securities. During the nine months ended September 30, 2016 and 2015 , the Company purchased $1.3 million and $1.0 million , respectively, of trading securities related to these deferred compensation plans. As a result of participant distributions, the Company sold $1.2 million of these trading securities during the nine months ended September 30, 2016 and $0.3 million during the nine months ended September 30, 2015 . 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. Derivatives In order to limit financial risk in the management of its assets, liabilities and debt, the Company may use derivative financial instruments such as foreign currency hedges, commodity hedges, interest rate hedges and interest rate swaps. All derivative financial instruments are matched with an existing Company asset, liability or forecasted transaction. Market value gains or losses on the derivative financial instrument are recognized in income when the effects of the related price changes of the underlying asset, liability or forecasted transaction are recognized in income. Derivative assets and derivative liabilities are not offset in the Condensed Consolidated Balance Sheet. Forward exchange contracts In 2016 and 2015 , the Company entered into a series of forward exchange contracts to purchase U.S. dollars in order to hedge exposure to fluctuating rates of exchange for both anticipated inventory purchases and forecasted sales by its subsidiaries that transact business in Canada. As of September 30, 2016 , the Company had 33 individual forward exchange contracts for an aggregate notional amount of $ 28.7 million , having various expiration dates through August 2017. These contracts have been designated as cash flow hedges in accordance with the accounting guidance for derivatives. The following table summarizes the results of cash flow hedging relationships for the three months ended September 30, 2016 and 2015 (in millions): Derivative Gain/(Loss) Recognized in Accumulated Other Comprehensive Loss (net of tax) Location of Gain/(Loss) Reclassified into Income Gain/(Loss) Reclassified into Earnings Effective Portion (net of tax) Derivative Instrument 2016 2015 (Effective Portion) 2016 2015 Forward exchange contract $ (0.3 ) $ 0.6 Net sales $ — $ — Cost of goods sold $ 0.3 $ 0.2 The following table summarizes the results of cash flow hedging relationships for the nine months ended September 30, 2016 and 2015 (in millions): Derivative Gain/(Loss) Recognized in Accumulated Other Comprehensive Loss (net of tax) Location of Gain/(Loss) Reclassified into Income Gain/(Loss) Reclassified into Earnings Effective Portion (net of tax) Derivative Instrument 2016 2015 (Effective Portion) 2016 2015 Forward exchange contract $ (1.8 ) $ 1.6 Net sales $ (0.2 ) $ — Cost of goods sold $ 0.3 $ 1.0 Hedge ineffectiveness was immaterial with respect to the forward exchange cash flow hedges during the three and nine months ended September 30, 2016 and 2015 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies 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 consideration of outside legal counsel and, if applicable, other experts. On October 16, 2015, Norfolk County Retirement System, a purported former holder of the Company’s Class B common stock, filed a complaint in the United States District Court for the District of Connecticut challenging the Reclassification of the Company’s dual-class common stock into a single class of common stock (the "Reclassification"). The complaint was captioned Norfolk County Retirement System v. Cardoso, et al., No. 3:15-cv-01507-AWT. The plaintiff asserted claims against the Company’s Board of Directors, Bessemer Trust Co., N.A. (“Bessemer”), as Trustee for the Trusts, and the Company (collectively, "Defendants"). The plaintiff claimed, among other things, that the Company and its Board of Directors had violated the Company’s certificate of incorporation by agreeing to make a payment to the holders of Class A common stock in connection with the Reclassification, and that the Board of Directors had violated its fiduciary duties by structuring the Reclassification in a supposedly coercive way and by allegedly making materially misleading disclosures to shareholders. The plaintiff also claimed, among other things, that Bessemer had aided and abetted the Board of Directors' purported violation of the certificate of incorporation and breach of fiduciary duties. As relief, the plaintiff demanded an injunction against the shareholder vote on the Reclassification, damages, an award of costs and attorneys’ fees, and other relief. At the same time as filing its complaint, the plaintiff sent a derivative demand letter to the Board of Directors, making similar allegations of wrongdoing, and demanding, among other things, that the Company file suit against the Board and Bessemer to recover damages supposedly sustained by the Company. On October 20, 2015, the plaintiff moved for expedited discovery in support of a forthcoming motion for an injunction. On October 21, 2015 and November 16, 2015, the Company amended its Registration Statement on Form S-4, making clear that the repurchase of an additional $250 million of the Company’s common stock was not contingent on the transaction, and providing more information about the Company’s certificate of incorporation and the Board’s evaluation of the Reclassification. The plaintiff then withdrew its motion for expedited discovery. On February 1, 2016, the plaintiff filed an amended direct and derivative complaint. The amended complaint contains allegations and claims for relief that are generally similar to the plaintiff’s previous complaint, but also asserts that the plaintiff has the right to sue derivatively on behalf of the Company to recoup damages supposedly sustained by the Company in connection with the Reclassification and includes derivative claims. Thereafter, the plaintiff and Defendants engaged in arm's-length settlement discussions. On June 21, 2016, the plaintiff and Defendants entered into a Stipulation of Settlement (the "Stipulation"), which provides for the complete settlement, release and dismissal of all claims alleged. The settlement is subject to, among other things, court approval. Under the Stipulation, among other things, if the Stipulation is approved and the settlement becomes final, (a) for a period of 150 days from and after the date upon which the settlement becomes final, Bessemer has agreed it will refrain from engaging in any sales of the Company's common stock unless it determines, in its sole discretion, that the failure to sell the Company's common stock will constitute a breach of its fiduciary duties to the Trusts and their beneficiaries and (b) for a period of 365 days from and after the date upon which the Stipulation was executed, the Company has agreed that it will refrain from knowingly repurchasing any shares of common stock of the Company from Bessemer in a block trade, in a privately negotiated transaction between the Company and Bessemer or through a stock repurchase program similar in structure to the Company's previous stock repurchase program authorized by the Company's Board of Directors. On August 24, 2016, the Court preliminarily approved the settlement and scheduled a hearing on final approval of the settlement for November 22, 2016.

In March 2016, the Company completed a public debt offering of $400 million of long-term unsecured, unsubordinated notes maturing in March 2026 and bearing interest at a fixed rate of 3.35% (the "2026 Notes"). Net proceeds from the issuance were $ 393.4 million after deducting the discount on the notes and offering expenses paid by the Company. The 2026 Notes are fixed rate indebtedness, 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 2026 Notes, as modified by the supplemental indenture creating such notes, or upon a change in control event as defined in such indenture. The Company was in compliance with all non-financial covenants under all Senior notes as of September 30, 2016 . As of September 30, 2016 and December 31, 2015 , the estimated fair value of the long-term debt was $1,058.8 million and $630.5 million , respectively, using quoted market prices in active markets for similar liabilities (Level 2). At December 31, 2015 , the Company had $ 48.2 million of short-term debt outstanding which consisted primarily of commercial paper. The Company had $ 5.8 million of short-term debt outstanding at September 30, 2016 . On December 16, 2015, the Company entered into a five -year revolving credit agreement (the "Credit Agreement") with a syndicate of lenders that provides a $750 million committed revolving credit facility. The revolving credit facility serves as a backup to the Company's commercial paper program. The single financial covenant in the Credit Agreement, which the Company was in compliance with at September 30, 2016 , requires that total debt not exceed 55% of total capitalization as of the last day of each fiscal quarter of the Company. At September 30, 2016 and December 31, 2015 the revolving credit facility had not been drawn against.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Hubbell Incorporated (“Hubbell”, the “Company”, “registrant”, “we”, “our” or “us”, which references shall include its divisions and subsidiaries) have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S.”) for complete financial statements. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. Operating results for the nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 . The balance sheet at December 31, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. During the fourth quarter of 2015, the Company identified a misclassification of costs between Cost of goods sold and Selling & administrative expenses that occurred during the first, second and third quarters of 2015, which has resulted in management revising its previously reported financial results to correct for such misclassification. The impact of the misclassification was to overstate Selling & administrative expenses and understate Cost of goods sold by $1.1 million for the three months ended September 30, 2015 . Accordingly, the originally reported Cost of goods sold of $585.9 million , the originally reported Gross profit of $291.1 million and the originally reported Selling & administrative expenses of $160.1 million for the three months ended September 30, 2015 were revised by $1.1 million in the accompanying Condensed Consolidated Statement of Income. In addition, the impact of the misclassification was to overstate Selling & administrative expenses and understate Cost of goods sold by $3.0 million for the nine months ended September 30, 2015 . Accordingly, the originally reported Cost of goods sold of $1,732.8 million , the originally reported Gross profit of $827.9 million , and the originally reported Selling & administrative expenses of $465.2 million for the nine months ended September 30, 2015 were revised by $3.0 million in the accompanying Condensed Consolidated Statement of Income. Management has concluded that the misclassifications are immaterial to the previously issued quarterly financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Hubbell Incorporated Annual Report on Form 10-K for the year ended December 31, 2015 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update (ASU 2016-09) relating to the accounting for share-based payments. Upon adoption, from a statement of income viewpoint, the new guidance will require all income tax effects of share-based awards to be recognized in the income statement when the awards vest or are settled, and allows companies an additional election in the methods to estimate forfeitures of share-based payments. It also increases the amount an employer can withhold to satisfy the employer's statutory income tax withholding obligation while still qualifying for the exception to liability classification of the share-based awards. From a statement of cash flows viewpoint, the new guidance requires that excess tax benefits be classified as an operating activity and cash paid to a tax authority when shares are withheld to satisfy the employer's statutory income tax withholdings be classified as a financing activity. This update is effective for fiscal years beginning after December 15, 2016 with early adoption permitted. The Company is currently assessing the impact of this standard on its financial statements. In February 2016, the FASB issued an Accounting Standards Update (ASU 2016-02) related to the accounting for leases. This guidance will require a lessee to recognize a right-to-use asset and a lease liability for both financing and operating leases, with the option of a policy election permitting an exception to this guidance for leases whose term is twelve months or less. For finance leases, the lessee will recognize interest expense and amortization of the right-of-use asset, and for operating leases the lessee will recognize a straight-line lease expense. This guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The new standard must be adopted using a modified retrospective transition at the beginning of the earliest comparative period presented. The Company is currently assessing the impact of adopting this standard on its financial statements. In May 2014, the FASB issued an Accounting Standards Update (ASU 2014-09) related to new revenue recognition guidance that supersedes the existing revenue recognition guidance and most industry-specific guidance applicable to revenue recognition. According to the new guidance an entity will apply a principles-based five step model to recognize revenue upon the transfer of promised goods or services to customers and in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for fiscal years beginning after December 15, 2017 with earlier application permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. This standard can be applied on either a retrospective or modified retrospective approach. Through the course of 2016 a number of ASU's have been issued which further refine the original guidance issued under ASU 2014-09 and are effective in conjunction with this original standard. The Company is currently assessing the impact of adopting these standards on its financial statements.
