Summary of Significant Accounti

Summary of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies A) Basis of Presentation The condensed consolidated financial statements have been prepared by The Middleby Corporation (the "company" or “Middleby”), pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The financial statements are unaudited and certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations, although the company believes that the disclosures are adequate to make the information not misleading. These financial statements should be read in conjunction with the financial statements and related notes contained in the company's 2017 Form 10-K. The company’s interim results are not necessarily indicative of future full year results for the fiscal year 2018 . In the opinion of management, the financial statements contain all adjustments, which are normal and recurring in nature, necessary to present fairly the financial position of the company as of March 31, 2018 and December 30, 2017 , the results of operations for the three months ended March 31, 2018 and April 1, 2017 and cash flows for the three months ended March 31, 2018 and April 1, 2017 . Certain prior year amounts have been reclassified to be consistent with current year presentation, including the non-operating components of pension benefit previously reporting Selling, general and administrative expenses to Net periodic pension benefit (other than service cost). Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses. Significant estimates and assumptions are used for, but are not limited to, allowances for doubtful accounts, reserves for excess and obsolete inventories, long-lived and intangible assets, warranty reserves, insurance reserves, income tax reserves, non-cash share-based compensation and post-retirement obligations. Actual results could differ from the company's estimates. B) Non-Cash Share-Based Compensation The company estimates the fair value of market-based stock awards and stock options at the time of grant and recognizes compensation cost over the vesting period of the awards and options. Non-cash share-based compensation expense was $0.1 million and $3.5 million for the first quarter periods ended March 31, 2018 and April 1, 2017 , respectively. C) Income Taxes A tax provision of $21.3 million , at an effective rate of 24.5% , was recorded during the three months period ended March 31, 2018 , as compared to a $22.7 million tax provision at a 24.3% in the prior year quarter. In comparison to the prior year quarter, the tax provision reflects a lower federal tax rate of 21.0% , as opposed to 35.0% in 2017, partially offset by additional taxes due under the Tax Cuts and Jobs Act of 2017. The 2017 tax provision was lower than the statutory rate of 35.0% primarily due to a discrete tax benefit recognized as a result of the adoption of ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting". In 2017 the company recorded a provisional transition tax charge and a change in deferred tax accounts associated with the Tax Cuts and Jobs Act of 2017. These provisional amounts will be finalized in 2018. D) Fair Value Measures Accounting Standards Codification ("ASC") 820 "Fair Value Measurements and Disclosures" defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair value into the following levels: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3 – Unobservable inputs based on our own assumptions. The company’s financial liabilities that are measured at fair value and are categorized using the fair value hierarchy are as follows (in thousands): Fair Value Level 1 Fair Value Level 2 Fair Value Level 3 Total As of March 31, 2018 Financial Assets: Interest rate swaps $ — $ 16,946 $ — $ 16,946 Financial Liabilities: Contingent consideration $ — $ — $ 803 $ 803 As of December 30, 2017 Financial Assets: Interest rate swaps $ — $ 10,266 $ — $ 10,266 Financial Liabilities: Contingent consideration $ — $ — $ 1,780 $ 1,780 The contingent consideration as of March 31, 2018 relates to the earnout provision recorded in conjunction with the acquisition of Scanico A/S ("Scanico"). The contingent consideration as of December 30, 2017 relates to the earnout provisions recorded in conjunction with the acquisitions of Desmon Food Service Equipment Company ("Desmon") and Scanico. The earnout provisions associated with these acquisitions are based upon performance measurements related to sales and earnings, as defined in the respective purchase agreements. On a quarterly basis, the company assesses the projected results for each of the acquired businesses in comparison to the earnout targets and adjusts the liability accordingly. E) Consolidated Statements of Cash Flows Cash paid for interest was $7.2 million and $5.8 million for the three months ended March 31, 2018 and April 1, 2017 , respectively. Cash payments totaling $5.7 million and $6.2 million were made for income taxes for the three months ended March 31, 2018 and April 1, 2017 , respectively.

Litigation Matters

Notes To Financial Statements [Abstract]
Litigation Matters	Litigation Matters From time to time, the company is subject to proceedings, lawsuits and other claims related to products, suppliers, employees, customers and competitors. The company maintains insurance to partially cover product liability, workers compensation, property and casualty, and general liability matters. The company is required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of accrual required, if any, for these contingencies is made after assessment of each matter and the related insurance coverage. The required accrual may change in the future due to new developments or changes in approach such as a change in settlement strategy in dealing with these matters. The company does not believe that any pending litigation will have a material effect on its financial condition, results of operations or cash flows.

Revenue Recognition (Notes)

Revenue Recognition (Notes)	3 Months Ended

Revenue Recognition [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Recognition Accounting Policy On December 31, 2017, we adopted the new accounting standard ASU No. 2014-09, “Revenue from Contracts with Customers" (ASC 606) using the modified retrospective method to contracts that were not completed as of December 30, 2017 . We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The adoption of ASC 606 represents a change in accounting principle that will also provide readers with enhanced revenue recognition disclosures. Revenue is recognized when the control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and represents the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The company’s contracts can have multiple performance obligations or just a single performance obligation. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each performance obligation using the company’s best estimate of the standalone selling price of each distinct good or service in the contract. Within the Commercial Foodservice Equipment and Residential Foodservice Equipment Groups, the estimated standalone selling price of equipment is based on observable prices. Within the Food Processing Equipment Group, the company estimates the standalone selling price based on expected cost to manufacture the good or complete the service plus an appropriate profit margin. Control may pass to the customer over time or at a point in time. In general, the Commercial Foodservice Equipment and Residential Foodservice Equipment Groups recognize revenue at the point in time control transfers to their customers based on contractual shipping terms. Revenue from equipment sold under our long-term contracts within the Food Processing Equipment group is recognized over time as the equipment is manufactured and assembled. Installation services provided in connection with the delivery of the equipment are also generally recognized as those services are rendered. Over time transfer of control is measured using an appropriate input measure (e.g., costs incurred or direct labor hours incurred in relation to total estimate). These measures include forecasts based on the best information available and therefore reflect the company's judgment to faithfully depict the transfer of the goods. Contract Estimates Accounting for long-term contracts within the Food Processing Equipment group involves the use of various techniques to estimate total contract revenue and costs. For the company’s long-term contracts, estimated profit for the equipment performance obligations is recognized as the equipment is manufactured and assembled. Profit on the equipment performance obligations is estimated as the difference between the total estimated revenue and expected costs to complete a contract. Contract cost estimates are based on labor productivity and availability, the complexity of the work to be performed; the cost and availability of materials and labor, and the performance of subcontractors. Contracts within the Commercial Foodservice and Residential Foodservice Equipment groups may contain variable consideration in the form of volume rebate programs. The company’s estimate of variable consideration is based on its experience with similarly situated customers using the portfolio approach. Practical Expedients and Policy Elections The company has taken advantage of the following practical expedients: • The company does not disclose information about remaining performance obligations that have original expected durations of one year or less. • The company generally expenses sales commissions when incurred because the amortization period would have been less than one year. These costs are recorded within selling, general and administrative expenses. • As the company’s standard payment terms are less than one year, the company does not assess whether a contract has a significant financing component. The company has made the following accounting policy elections permitted by ASC 606: • The company treats shipping and handling activities performed after the customer obtains control of the good as a contract fulfillment activity. • Sales, use and value added taxes assessed by governmental authorities are excluded from the measurement of the transaction price within the company’s contracts with its customers. Adoption of ASC 606 As a result of the adoption of ASC 606, the company has changed its accounting policy for revenue recognition as detailed below. Equipment Under the company’s historical accounting policies, revenue under long-term sales contracts within the Food Processing Equipment Group was recognized using the percentage of completion method. Upon adoption, a number of contracts that were not completed as of December 31, 2017 did not meet the requirements for recognition of revenue over time under ASC 606. As such the revenue is deferred and recognized at a point in time. Installation Services Under the company’s historical accounting policies, the company used the completed contract method for installation services associated with equipment sold within the Food Processing Equipment Group. Under ASC 606, the Company recognizes revenue from installation services over the period the services are rendered. The cumulative effect of the changes made to our December 30, 2017 Condensed Consolidated Balance Sheet for the adoption of ASC 606 using the modified retrospective method to contracts that were not completed as of December 30, 2017 were as follows: Balance at December 30, 2017 (as reported) Adjustments due to ASC 606 Balance at December 30, 2017 (as adjusted) (in thousands) Balance Sheet Assets Accounts receivable $ 328,421 $ (122 ) $ 328,299 Inventories, net 424,639 14,993 439,632 Prepaid expenses and other 55,427 (4,018 ) 51,409 Long-term deferred tax assets 44,565 1,319 45,884 Liabilities & Stockholders' Equity Accrued expenses 322,171 16,557 338,728 Retained earnings $ 1,697,618 $ (4,405 ) $ 1,693,213 In accordance with the requirements of ASC 606, the adoption of ASC 606 had no impact on cash provided by operating activities within the company's Condensed Consolidated Statement of Cash Flows. The impact of adoption on our Condensed Consolidated Statement of Comprehensive Income and Condensed Consolidated Balance Sheet are as follows: Three Months Ended March 31, 2018 As Reported Balances without ASC 606 Effect of Change (in thousands) Net sales $ 584,800 $ 570,658 $ 14,142 Cost of sales 373,167 362,686 10,481 Provision for income taxes 21,281 20,310 971 Net earnings $ 65,420 $ 62,731 $ 2,689 Basic earnings per share $ 1.18 $ 1.13 Diluted earnings per share $ 1.18 $ 1.13 Balance as of March 31, 2018 As Reported Balances without ASC 606 Effect of Change (in thousands) Assets Inventories, net $ 459,151 $ 453,710 $ 5,441 Prepaid expenses and other 48,464 51,630 (3,166 ) Liabilities Accrued expenses 305,132 310,104 4,180 Long-term deferred tax liability 91,433 90,816 (456 ) Equity Retained earnings $ 1,757,500 $ 1,756,051 $ (1,449 ) Disaggregation of Revenue We disaggregate our net sales by reportable operation segment and geographical location as we believe it best depicts how the nature, timing and uncertainty of our net sales and cash flows are affected by economic factors. In general, the Commercial Foodservice Equipment and Residential Foodservice Equipment Groups recognize revenue at the point in time control transfers to their customers based on contractual shipping terms. Revenue from equipment sold under our long-term contracts within the Food Processing Equipment group is recognized over time as the equipment is manufactured and assembled.

Contract assets are transferred to receivables when the right to consideration becomes unconditional. Accounts receivable are not considered contract assets under the new revenue standard as contract assets are conditioned upon the company's future satisfaction of a performance obligation. Accounts receivable, in contracts, are unconditional rights to consideration. Contract liabilities relate to advance consideration received from customers for which revenue has not been recognized. Current contract liabilities are recorded in accrued expenses in the Condensed Consolidated Balance Sheet. Contract liabilities are reduced when the associated revenue from the contract is recognized. The following table provides information about contract assets and contract liabilities from contracts with customers: Mar 31, 2018 At Adoption (in thousands) Contract assets $ 11,315 $ 16,753 Contract liabilities 51,276 47,647 During the three months period ended March 31, 2018 , the company reclassified $7.9 million to receivable of which was included in the contract asset balance at the beginning of the period.

Warranty Costs	Warranty Costs In the normal course of business the company issues product warranties for specific product lines and provides for the estimated future warranty cost in the period in which the sale is recorded. The estimate of warranty cost is based on contract terms and historical warranty loss experience that is periodically adjusted for recent actual experience. Because warranty estimates are forecasts that are based on the best available information, actual claims costs may differ from amounts provided. Adjustments to initial obligations for warranties are made as changes in the obligations become reasonably estimable. A rollforward of the warranty reserve is as follows: Three Months Ended Mar 31, 2018 (in thousands) Balance as of December 30, 2017 $ 52,834 Warranty reserve related to acquisitions 69 Warranty expense 14,488 Warranty claims (13,322 ) Balance as of March 31, 2018 $ 54,069

As of March 31, 2018 , the company had $1,043.1 million of borrowings outstanding under the Credit Facility, including $1,001.0 million of borrowings in U.S. Dollars and $42.1 million of borrowings denominated in British Pounds. The company also had $8.3 million in outstanding letters of credit as of March 31, 2018 , which reduces the borrowing availability under the Credit Facility. Remaining borrowing availability under this facility was $1.4 billion at March 31, 2018 . At March 31, 2018 , borrowings under the Credit Facility accrued interest at a rate of 1.25% above LIBOR per annum or 0.25% above the highest of the prime rate, the federal funds rate plus 0.50% and one month LIBOR plus 1.00% . The average interest rate per annum on the debt under the Credit Facility was equal to 2.94% for the period. The interest rates on borrowings under the Credit Facility may be adjusted quarterly based on the company’s Funded Debt less Unrestricted Cash to Pro Forma EBITDA (the “Leverage Ratio”) on a rolling four-quarter basis. Additionally, a commitment fee based upon the Leverage Ratio is charged on the unused portion of the commitments under the Credit Facility. This variable commitment fee was equal to 0.20% per annum as of March 31, 2018 . In addition, the company has other international credit facilities to fund working capital needs outside the United States and the United Kingdom. At March 31, 2018 , these foreign credit facilities amounted to $5.7 million in U.S. Dollars with a weighted average per annum interest rate of approximately 5.85% . The company’s debt is reflected on the balance sheet at cost. The company believes its interest rate margins on its existing debt are consistent with current market conditions and therefore the carrying value of debt reflects the fair value. The interest rate margin is based on the company's Leverage Ratio. The company estimated the fair value of its loans by calculating the upfront cash payment a market participant would require to assume the company’s obligations. The upfront cash payment is the amount that a market participant would be able to lend to achieve sufficient cash inflows to cover the cash outflows under the company’s senior secured revolving credit facility assuming the facility was outstanding in its entirety until maturity. Since the company maintains its borrowings under a revolving credit facility and there is no predetermined borrowing or repayment schedule, for purposes of this calculation the company calculated the fair value of its obligations assuming the current amount of debt at the end of the period was outstanding until the maturity of the company’s Credit Facility in July 2021. Although borrowings could be materially greater or less than the current amount of borrowings outstanding at the end of the period, it is not practical to estimate the amounts that may be outstanding during future periods. The carrying value and estimated aggregate fair value, a level 2 measurement, based primarily on market prices, of debt is as follows (in thousands): Mar 31, 2018 Dec 30, 2017 Carrying Value Fair Value Carrying Value Fair Value Total debt $ 1,048,998 $ 1,048,998 $ 1,028,881 $ 1,028,881 The company uses floating-to-fixed interest rate swap agreements to hedge variable interest rate risk associated with the Credit Facility. At March 31, 2018 , the company had outstanding floating-to-fixed interest rate swaps totaling $499.0 million notional amount carrying an average interest rate of 1.66% that mature in more than 12 months but less than 84 months. The company believes that its current capital resources, including cash and cash equivalents, cash expected to be generated from operations, funds available from its current lenders and access to the credit and capital markets will be sufficient to finance its operations, debt service obligations, capital expenditures, product development and expenditures for the foreseeable future. The terms of the Credit Facility limit the ability of the company and its subsidiaries to, with certain exceptions: incur indebtedness; grant liens; engage in certain mergers, consolidations, acquisitions and dispositions; make restricted payments; enter into certain transactions with affiliates; and requires, among other things, the company to satisfy certain financial covenants: (i) a minimum Interest Coverage Ratio (as defined in the Credit Facility) of 3.00 to 1.00 and (ii) a maximum Leverage Ratio of Funded Debt less Unrestricted Cash to Pro Forma EBIDTA (each as defined in the Credit Facility) of 3.50 to 1.00 , which may be adjusted to 4.00 to 1.00 for a four consecutive fiscal quarter period in connection with certain qualified acquisitions, subject to the terms and conditions contained in the Credit Facility. The Credit Facility is secured by substantially all of the assets of Middleby Marshall, the company and the company's domestic subsidiaries and is unconditionally guaranteed by, subject to certain exceptions, the company and certain of the company's direct and indirect material foreign and domestic subsidiaries. The Credit Facility contains certain customary events of default, including, but not limited to, the failure to make required payments; bankruptcy and other insolvency events; the failure to perform certain covenants; the material breach of a representation or warranty; non-payment of certain other indebtedness; the entry of undischarged judgments against the company or any subsidiary for the payment of material uninsured amounts; the invalidity of the company guarantee or any subsidiary guaranty; and a change of control of the company. At March 31, 2018 , the company was in compliance with all covenants pursuant to its borrowing agreements.

Financial Instruments

Notes To Financial Statements [Abstract]
Financial Instruments	Financial Instruments ASC 815 “Derivatives and Hedging” requires an entity to recognize all derivatives as either assets or liabilities and measure those instruments at fair value. Derivatives that do not qualify as a hedge must be adjusted to fair value in earnings. If a derivative does qualify as a hedge under ASC 815, changes in the fair value will either be offset against the change in the fair value of the hedged assets, liabilities or firm commitments or recognized in other accumulated comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a hedge's change in fair value will be immediately recognized in earnings. Foreign Exchange : The company uses foreign currency forward, foreign exchange swaps and option purchase and sales contracts to hedge its exposure to changes in foreign currency exchange rates. The company’s primary hedging activities are to mitigate its exposure to changes in exchange rates on intercompany and third party trade receivables and payables. The company does not currently enter into derivative financial instruments for speculative purposes. In managing its foreign currency exposures, the company identifies and aggregates naturally occurring offsetting positions and then hedges residual balance sheet exposures. The fair value of the forward and option contracts was a gain of $0.1 million at the end of the first quarter of 2018 . Interest Rate: The company has entered into interest rate swaps to fix the interest rate applicable to certain of its variable-rate debt. The agreements swap one-month LIBOR for fixed rates. The company has designated these swaps as cash flow hedges and all changes in fair value of the swaps are recognized in accumulated other comprehensive income. As of March 31, 2018 , the fair value of these instruments was an asset of $16.9 million . The change in fair value of these swap agreements in the first three months of 2018 was a gain of $6.7 million , net of taxes. The following table summarizes the company’s fair value of interest rate swaps (in thousands): Condensed Consolidated Balance Sheet Presentation Mar 31, 2018 Dec 30, 2017 Fair value Other assets $ 16,946 $ 10,266 The impact on earnings from interest rate swaps was as follows (in thousands): Three Months Ended Presentation of Gain/(loss) Mar 31, 2018 Apr 1, 2017 Gain/(loss) recognized in accumulated other comprehensive income Other comprehensive income $ 6,620 $ 312 Gain/(loss) reclassified from accumulated other comprehensive income (effective portion) Interest expense $ (12 ) $ (522 ) Gain/(loss) recognized in income (ineffective portion) Other expense $ 48 $ (7 ) Interest rate swaps are subject to default risk to the extent the counterparties are unable to satisfy their settlement obligations under the interest rate swap agreements. The company reviews the credit profile of the financial institutions that are counterparties to such swap agreements and assesses their creditworthiness prior to entering into the interest rate swap agreements and throughout the term. The interest rate swap agreements typically contain provisions that allow the counterparty to require early settlement in the event that the company becomes insolvent or is unable to maintain compliance with its covenants under its existing debt agreements.

Notes To Financial Statements [Abstract]
Employee Retirement Plans	Employee Retirement Plans (a) Pension Plans U.S. Plans: The company maintains a non-contributory defined benefit plan for its union employees at the Elgin, Illinois facility. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 30, 2002, and no further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 30, 2002 upon reaching retirement age. The company maintains a non-contributory defined benefit plan for its employees at the Smithville, Tennessee facility, which was acquired as part of the Star acquisition. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 1, 2008, and no further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 1, 2008 upon reaching retirement age. The company also maintains a retirement benefit agreement with its Chairman ("Chairman Plan"). The retirement benefits are based upon a percentage of the Chairman’s final base salary. Non-U.S. Plans: The company maintains a defined benefit plan for its employees at the Wrexham, the United Kingdom facility, which was acquired as part of the Lincat acquisition. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 30, 2010 prior to Middleby’s acquisition of the company. No further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 30, 2010 upon reaching retirement age. The company maintains several pension plans related to AGA and its subsidiaries (collectively, the "AGA Group"), the most significant being the Aga Rangemaster Group Pension Scheme, which covers the majority of employees in the United Kingdom. Membership in the plan on a defined benefit basis of pension provision was closed to new entrants in 2001. The plan became open to new entrants on a defined contribution basis of pension provision in 2002, but was generally closed to new entrants on this basis during 2014. The other, much smaller, defined benefit pension plans operating within the AGA Group cover employees in France, Ireland and the United Kingdom. All pension plan assets are held in separate trust funds although the net defined benefit pension obligations are included in the company's consolidated balance sheet. The following table summarizes the company's net periodic pension benefit related to the AGA Group pension plans (in thousands): Three Months Ended March 31, 2018 April 1, 2017 Net Periodic Pension Benefit: Service cost $ 977 $ 964 Interest cost 8,278 7,764 Expected return on assets (19,278 ) (16,774 ) Amortization of net (gain) loss 1,032 720 Curtailment loss (gain) 287 — Pension settlement gain (24 ) (48 ) $ (8,728 ) $ (7,374 ) The pension costs for all other plans of the company were not material during the period. On December 31, 2017, the company adopted ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". The service cost component is recognized within Selling, general and administrative expenses and the non-operating components of pension benefit are included within Net periodic pension benefit (other than service cost) in the Condensed Consolidated Statements of Comprehensive Income. The adoption of this standard resulted in a reclassification for the three months ended April 1, 2017, in which previously reported Selling, general and administrative expenses was increased by $8.3 million . Net income did not change as a result of the adoption of this standard. (b) Defined Contribution Plans The company maintains two separate defined contribution 401K savings plans covering all employees in the United States. These two plans separately cover the union employees at the Elgin, Illinois facility and all other remaining union and non-union employees in the United States. The company also maintains defined contribution plans for its U.K. based employees.

Restructuring

Subsequent Events [Abstract]
Acquisition Integration Initiatives	16) Restructuring Commercial Foodservice Equipment Group: During the fiscal years 2018 and 2017, the company undertook cost reduction initiatives related to the entire Commercial Foodservice Equipment Group. These actions, which are not material to the company's operations, resulted in a charge of $1.0 million in the three months ended March 31, 2018 primarily for severance related to headcount reductions and consolidation of manufacturing operations. These expenses are reflected in restructuring expenses in the Condensed Consolidated Statements of Comprehensive Income. The company estimates that these restructuring initiatives will result in future cost savings of approximately $10.0 million annually. The realization of the savings began in 2017 and will continue into the first six months of fiscal year 2018 and the restructuring costs in the future are not expected to be significant related to these actions. Residential Kitchen Equipment Group: During fiscal years 2017, 2016 and 2015, the company undertook acquisition integration initiatives related to the AGA Group within the Residential Kitchen Equipment Group. These initiatives included organizational restructuring, headcount reductions and consolidation and disposition of certain facilities and business operations, including the impairment of equipment. The company recorded additional expense of $0.7 million in the three months ended March 31, 2018 , related to the AGA Group. The expense primarily related to additional headcount reductions in conjunction with disposition of certain facilities and business operations. This expense is reflected in restructuring expenses in the Condensed Consolidated Statements of Comprehensive Income. The cumulative expenses incurred to date for these initiatives is approximately $41.3 million . The company estimated that the main restructuring initiatives in 2017 would result in future cost savings of approximately $20.0 million annually. The realization of the savings began in 2017 and will continue into the first six months of fiscal year 2018, primarily related to the compensation and facility costs. The company anticipates that all severance obligations for the Residential Kitchen Equipment Group will be paid by the end of fiscal year 2018. The lease obligations extend through December 2019. The costs and corresponding reserve balances for the Residential Kitchen Equipment Group are summarized as follows (in thousands): Severance/Benefits Facilities/Operations Other Total Balance as of December 30, 2017 $ 3,698 $ 1,467 $ 157 $ 5,322 Expenses 777 (183 ) 146 740 Exchange 126 26 3 155 Payments/Utilization (2,307 ) (123 ) (67 ) (2,497 ) Balance as of March 31, 2018 $ 2,294 $ 1,187 $ 239 $ 3,720

Summary of Significant Accoun19

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	A) Basis of Presentation The condensed consolidated financial statements have been prepared by The Middleby Corporation (the "company" or “Middleby”), pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The financial statements are unaudited and certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations, although the company believes that the disclosures are adequate to make the information not misleading. These financial statements should be read in conjunction with the financial statements and related notes contained in the company's 2017 Form 10-K. The company’s interim results are not necessarily indicative of future full year results for the fiscal year 2018 . In the opinion of management, the financial statements contain all adjustments, which are normal and recurring in nature, necessary to present fairly the financial position of the company as of March 31, 2018 and December 30, 2017 , the results of operations for the three months ended March 31, 2018 and April 1, 2017 and cash flows for the three months ended March 31, 2018 and April 1, 2017 .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses. Significant estimates and assumptions are used for, but are not limited to, allowances for doubtful accounts, reserves for excess and obsolete inventories, long-lived and intangible assets, warranty reserves, insurance reserves, income tax reserves, non-cash share-based compensation and post-retirement obligations. Actual results could differ from the company's estimates.
Non-Cash Share-Based Compensation	B) Non-Cash Share-Based Compensation The company estimates the fair value of market-based stock awards and stock options at the time of grant and recognizes compensation cost over the vesting period of the awards and options. Non-cash share-based compensation expense was $0.1 million and $3.5 million for the first quarter periods ended March 31, 2018 and April 1, 2017 , respectively.
Income Tax Contingencies	C) Income Taxes A tax provision of $21.3 million , at an effective rate of 24.5% , was recorded during the three months period ended March 31, 2018 , as compared to a $22.7 million tax provision at a 24.3% in the prior year quarter. In comparison to the prior year quarter, the tax provision reflects a lower federal tax rate of 21.0% , as opposed to 35.0% in 2017, partially offset by additional taxes due under the Tax Cuts and Jobs Act of 2017. The 2017 tax provision was lower than the statutory rate of 35.0% primarily due to a discrete tax benefit recognized as a result of the adoption of ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Accounting".
Fair Value Measures	D) Fair Value Measures Accounting Standards Codification ("ASC") 820 "Fair Value Measurements and Disclosures" defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair value into the following levels: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3 – Unobservable inputs based on our own assumptions. The company’s financial liabilities that are measured at fair value and are categorized using the fair value hierarchy are as follows (in thousands): Fair Value Level 1 Fair Value Level 2 Fair Value Level 3 Total As of March 31, 2018 Financial Assets: Interest rate swaps $ — $ 16,946 $ — $ 16,946 Financial Liabilities: Contingent consideration $ — $ — $ 803 $ 803 As of December 30, 2017 Financial Assets: Interest rate swaps $ — $ 10,266 $ — $ 10,266 Financial Liabilities: Contingent consideration $ — $ — $ 1,780 $ 1,780

Revenue Recognition [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Accounting Policy On December 31, 2017, we adopted the new accounting standard ASU No. 2014-09, “Revenue from Contracts with Customers" (ASC 606) using the modified retrospective method to contracts that were not completed as of December 30, 2017 . We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The adoption of ASC 606 represents a change in accounting principle that will also provide readers with enhanced revenue recognition disclosures. Revenue is recognized when the control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and represents the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The company’s contracts can have multiple performance obligations or just a single performance obligation. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each performance obligation using the company’s best estimate of the standalone selling price of each distinct good or service in the contract. Within the Commercial Foodservice Equipment and Residential Foodservice Equipment Groups, the estimated standalone selling price of equipment is based on observable prices. Within the Food Processing Equipment Group, the company estimates the standalone selling price based on expected cost to manufacture the good or complete the service plus an appropriate profit margin. Control may pass to the customer over time or at a point in time. In general, the Commercial Foodservice Equipment and Residential Foodservice Equipment Groups recognize revenue at the point in time control transfers to their customers based on contractual shipping terms. Revenue from equipment sold under our long-term contracts within the Food Processing Equipment group is recognized over time as the equipment is manufactured and assembled. Installation services provided in connection with the delivery of the equipment are also generally recognized as those services are rendered. Over time transfer of control is measured using an appropriate input measure (e.g., costs incurred or direct labor hours incurred in relation to total estimate). These measures include forecasts based on the best information available and therefore reflect the company's judgment to faithfully depict the transfer of the goods. Contract Estimates Accounting for long-term contracts within the Food Processing Equipment group involves the use of various techniques to estimate total contract revenue and costs. For the company’s long-term contracts, estimated profit for the equipment performance obligations is recognized as the equipment is manufactured and assembled. Profit on the equipment performance obligations is estimated as the difference between the total estimated revenue and expected costs to complete a contract. Contract cost estimates are based on labor productivity and availability, the complexity of the work to be performed; the cost and availability of materials and labor, and the performance of subcontractors. Contracts within the Commercial Foodservice and Residential Foodservice Equipment groups may contain variable consideration in the form of volume rebate programs. The company’s estimate of variable consideration is based on its experience with similarly situated customers using the portfolio approach. Practical Expedients and Policy Elections The company has taken advantage of the following practical expedients: • The company does not disclose information about remaining performance obligations that have original expected durations of one year or less. • The company generally expenses sales commissions when incurred because the amortization period would have been less than one year. These costs are recorded within selling, general and administrative expenses. • As the company’s standard payment terms are less than one year, the company does not assess whether a contract has a significant financing component. The company has made the following accounting policy elections permitted by ASC 606: • The company treats shipping and handling activities performed after the customer obtains control of the good as a contract fulfillment activity. • Sales, use and value added taxes assessed by governmental authorities are excluded from the measurement of the transaction price within the company’s contracts with its customers. Adoption of ASC 606 As a result of the adoption of ASC 606, the company has changed its accounting policy for revenue recognition as detailed below. Equipment Under the company’s historical accounting policies, revenue under long-term sales contracts within the Food Processing Equipment Group was recognized using the percentage of completion method. Upon adoption, a number of contracts that were not completed as of December 31, 2017 did not meet the requirements for recognition of revenue over time under ASC 606. As such the revenue is deferred and recognized at a point in time. Installation Services Under the company’s historical accounting policies, the company used the completed contract method for installation services associated with equipment sold within the Food Processing Equipment Group. Under ASC 606, the Company recognizes revenue from installation services over the period the services are rendered.
