Accounting Policies [Abstract]
Business Overview and Significant Accounting Policies	Business Overview and Significant Accounting Policies Unless we state otherwise or the context otherwise requires, references to "Masonite," "we," "our," "us" and the "Company" in these notes to the condensed consolidated financial statements refer to Masonite International Corporation and its subsidiaries. Description of Business Masonite International Corporation is one of the largest manufacturers of doors in the world, with significant market share in both interior and exterior door products. Masonite operates 65 manufacturing locations in 8 countries and sells doors to customers throughout the world, including the United States, Canada and the United Kingdom. Basis of Presentation We prepare these unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") and applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments consisting of normal and recurring entries considered necessary for a fair presentation of the results for the interim periods presented have been included. All significant intercompany balances and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts in the financial statements and accompanying notes. These estimates are based on information available as of the date of the unaudited condensed consolidated financial statements; therefore, actual results could differ from those estimates. Interim results are not necessarily indicative of the results for a full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended January 1, 2017, as filed with the SEC. There have been no changes in the significant accounting policies from those that were disclosed in the fiscal year 2016 audited consolidated financial statements, other than as noted below. Our fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31. In a 52-week year, each fiscal quarter consists of 13 weeks. For ease of disclosure, the 13-week periods are referred to as three-month periods. Changes in Accounting Standards and Policies Adoption of Recent Accounting Pronouncements In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-11, "Simplifying the Measurement of Inventory," which amended ASC 330, "Inventory." This ASU requires the measurement of inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years; early adoption is permitted. The adoption of this standard did not have a material impact on the presentation of our financial statements. Other Recent Accounting Pronouncements not yet Adopted In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which amends ASC 715, “Retirement Benefits”. This ASU requires disaggregation of the service cost component from the other components of net benefit cost. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years; early adoption is permitted and retrospective application is required. We are in the process of evaluating this guidance to determine the impact it may have on our financial statements. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment", which amends ASC 350 "Intangibles - Goodwill and Other". This ASU simplifies the accounting for goodwill impairments and allows a goodwill impairment charge to be based upon the amount of a reporting unit's carrying value in excess of its fair value; thus, eliminating what is currently known as "Step 2" under the current guidance. This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods; early adoption is permitted and prospective application is required. We are in the process of evaluating this guidance to determine the impact it may have on our financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers - Deferral of the Effective Date," and the guidance will now be effective for annual and interim periods beginning on or after December 15, 2017; early application is permitted only as of annual and interim reporting periods beginning after December 15, 2016. While we are still in the process of evaluating the effect of adoption on our consolidated financial statements and are currently assessing our contracts with customers, we do not currently expect the adoption of the new standard to have a material impact on consolidated net income (loss) attributable to Masonite, cash flows or our consolidated balance sheets. We plan to adopt this standard using the retrospective method and adoption will be effective as of January 1, 2018.

Our ten largest customers accounted for 54.7% and 57.3% of total accounts receivable as of April 2, 2017 , and January 1, 2017 , respectively. Our two largest customers, The Home Depot, Inc. and Lowe's Companies, Inc., each accounted for more than 10% of the consolidated gross accounts receivable balance as of April 2, 2017 , and January 1, 2017 . No other individual customers accounted for greater than 10% of consolidated gross accounts receivable balance at either April 2, 2017 , or January 1, 2017 . The allowance for doubtful accounts balance was $1.1 million and $1.0 million as of April 2, 2017 , and January 1, 2017 , respectively. We maintain accounts receivable sales programs with third parties (the "AR Sales Programs"). Under the AR Sales Programs, we can transfer ownership of eligible trade accounts receivable of certain customers. Receivables are sold outright to third parties who assume the full risk of collection, without recourse to us in the event of a loss. Transfers of receivables under these programs are accounted for as sales. Proceeds from the transfers reflect the face value of the accounts receivable less a discount. Receivables sold under the AR Sales Programs are excluded from trade accounts receivable in the condensed consolidated balance sheets and are included in cash flows from operating activities in the condensed consolidated statements of cash flows. The discounts on the sales of trade accounts receivable sold under the AR Sales Programs were not material for any of the periods presented and were recorded in selling, general and administration expense within the condensed consolidated statements of comprehensive income (loss).

The 2023 Notes were issued in a private placement for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and to buyers outside the United States pursuant to Regulation S under the Securities Act. The 2023 Notes were issued without registration rights and are not listed on any securities exchange. The 2023 Notes were issued at par and bear interest at 5.625% per annum, payable in cash semiannually in arrears on March 15 and September 15 of each year and are due March 15, 2023. We received net proceeds of $467.9 million after deducting $7.1 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the 2023 Notes using the effective interest method. The net proceeds from the 2023 Notes, together with available cash balances, were used to redeem $500.0 million aggregate principal of prior 8.25% senior unsecured notes due 2021 and to pay related premiums, fees and expenses. We may redeem the 2023 Notes, in whole or in part, at any time prior to March 15, 2018, at a price equal to 100% of the principal amount plus the applicable premium, plus accrued and unpaid interest, if any, to the date of redemption. The applicable premium means, with respect to a note at any date of redemption, the greater of (i) 1.00% of the then-outstanding principal amount of such note and (ii) the excess of (a) the present value at such date of redemption of (1) the redemption price of such note at March 15, 2018, plus (2) all remaining required interest payments due on such note through such date (excluding accrued but unpaid interest to the date of redemption), computed using a discount rate equal to the Treasury Rate, as described in the indenture, plus 50 basis points, over (b) the principal amount of such note on such redemption date. We may also redeem the 2023 Notes, in whole or in part, at any time on or after March 15, 2018, at the applicable redemption prices specified under the indenture governing the 2023 Notes, plus accrued and unpaid interest, if any, to the date of redemption. If we experience certain changes of control or consummate certain asset sales and do not reinvest the net proceeds, we must offer to repurchase all of the 2023 Notes at a purchase price of 101.00% of their principal amount, plus accrued and unpaid interest, if any, to the repurchase date. Obligations under the 2023 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by certain of our directly or indirectly wholly-owned subsidiaries. The indenture governing the 2023 Notes contains restrictive covenants that, among other things, limit our ability and the ability of our subsidiaries to: (i) incur additional debt and issue disqualified or preferred stock, (ii) make restricted payments, (iii) sell assets, (iv) create or permit restrictions on the ability of our restricted subsidiaries to pay dividends or make other distributions to the parent company, (v) create or incur certain liens, (vi) enter into sale and leaseback transactions, (vii) merge or consolidate with other entities and (viii) enter into transactions with affiliates. The foregoing limitations are subject to exceptions as set forth in the indenture governing the 2023 Notes. In addition, if in the future the 2023 Notes have an investment grade rating from at least two nationally recognized statistical rating organizations, certain of these covenants will be replaced with a less restrictive covenant. The indenture governing the 2023 Notes contains customary events of default (subject in certain cases to customary grace and cure periods). As of April 2, 2017 , and January 1, 2017 , we were in compliance with all covenants under the indenture governing the 2023 Notes. ABL Facility On April 9, 2015, we and certain of our subsidiaries entered into a $150.0 million asset-based revolving credit facility (the "ABL Facility") maturing on April 9, 2020. The borrowing base is calculated based on a percentage of the value of selected U.S. and Canadian accounts receivable and inventory, less certain ineligible amounts. Obligations under the ABL Facility are secured by a first priority security interest in substantially all of the current assets of Masonite and our subsidiaries. In addition, obligations under the ABL Facility are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis, by certain of our directly or indirectly wholly-owned subsidiaries. Borrowings under the ABL Facility bear interest at a rate equal to, at our option, (i) the Base Rate, Canadian Prime Rate or Canadian Base Rate (each as defined in the Amended and Restated Credit Agreement) plus a margin ranging from 0.25% to 0.75% per annum, or (ii) the Eurodollar Base Rate or BA Rate (each as defined in the Amended and Restated Credit Agreement), plus a margin ranging from 1.25% to 1.75% per annum. In addition to paying interest on any outstanding principal under the ABL Facility a commitment fee is payable on the undrawn portion of the ABL Facility in an amount equal to 0.25% per annum of the average daily balance of unused commitments during each calendar quarter. The ABL Facility contains various customary representations, warranties and covenants by us that, among other things, and subject to certain exceptions, restrict Masonite's ability and the ability of our subsidiaries to: (i) pay dividends on our common shares and make other restricted payments, (ii) make investments and acquisitions, (iii) engage in transactions with our affiliates, (iv) sell assets, (v) merge and (vi) create liens. The Amended and Restated Credit Agreement amended the ABL Facility to, among other things, (i) permit us to incur unlimited unsecured debt as long as such debt does not contain covenants or default provisions that are more restrictive than those contained in the ABL Facility, (ii) permit us to incur debt as long as the pro forma secured leverage ratio is less than 4.5 to 1.0 , and (iii) add certain additional exceptions and exemptions under the restricted payment, investment and indebtedness covenants (including increasing the amount of certain debt permitted to be incurred under an existing exception). As of April 2, 2017 , and January 1, 2017 , we were in compliance with all covenants under the credit agreement governing the ABL Facility and there were no amounts outstanding under the ABL Facility.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share Based Compensation Plans	Share Based Compensation Plans Share based compensation expense was $2.4 million and $3.7 million for the three months ended April 2, 2017 , and April 3, 2016 , respectively. As of April 2, 2017 , the total remaining unrecognized compensation expense related to share based compensation amounted to $23.2 million , which will be amortized over the weighted average remaining requisite service period of 2.1 years. Share based compensation expense is recognized using a graded-method approach, or to a lesser extent a cliff-vesting approach, depending on the terms of the individual award and is classified within selling, general and administration expenses in the condensed consolidated statements of comprehensive income (loss). All share based awards are settled through issuance of new shares of our common stock. The share based award agreements contain restrictions on sale or transfer other than in limited circumstances. All other transfers would cause the share based awards to become null and void. Equity Incentive Plans Prior to July 9, 2012 , we had a management equity incentive plan (the "2009 Plan"). The 2009 Plan required granting by June 9, 2012, equity instruments which upon exercise would result in management (excluding directors) owning 9.55% of our common equity ( 3,554,811 shares) on a fully diluted basis, after giving consideration to the potential exercise of warrants and the equity instruments granted to directors. Under the 2009 Plan, we were required to issue equity instruments to directors that represented 0.90% ( 335,004 shares) of the common equity on a fully diluted basis. The requirement for issuance to employees was satisfied in June 2012, and the requirement for issuance to directors was satisfied in July 2009. No awards have been granted under the 2009 Plan since May 30, 2012, and no future awards will be granted under the 2009 Plan; however, all outstanding awards under the 2009 Plan will continue to be governed by their existing terms. Aside from shares issuable for outstanding awards, there are no further shares of common stock available for future issuance under the 2009 Plan. On July 12, 2012 , the Board of Directors adopted the Masonite International Corporation 2012 Equity Incentive Plan, which was amended on June 21, 2013, by our Board of Directors, further amended and restated by our Board of Directors on February 23, 2015, and approved by our shareholders on May 12, 2015 (as amended and restated, the "2012 Plan"). The 2012 Plan was adopted because the Board believes awards granted will help to attract, motivate and retain employees and non-employee directors, align employee and stockholder interests and encourage a performance-based culture built on employee stock ownership. The 2012 Plan permits us to offer eligible directors, employees and consultants cash and share-based incentives, including stock options, stock appreciation rights, restricted stock, other share-based awards (including restricted stock units) and cash-based awards. The 2012 Plan is effective for ten years from the date of its adoption. Awards granted under the 2012 Plan are at the discretion of the Human Resources and Compensation Committee of the Board of Directors. The Human Resources and Compensation Committee may grant any award under the 2012 Plan in the form of a performance award. The 2012 Plan may be amended, suspended or terminated by the Board at any time; provided, that any amendment, suspension or termination which impairs the rights of a participant is subject to such participant's consent and; provided further, that certain material amendments are subject to shareholder approval. The aggregate number of common shares that can be issued with respect to equity awards under the 2012 Plan cannot exceed 2,000,000 shares plus the number of shares subject to existing grants under the 2009 Plan that may expire or be forfeited or cancelled. As of April 2, 2017 , there were 1,459,106 shares of common stock available for future issuance under the 2012 Plan. Deferred Compensation Plan We offer to certain of our employees and directors a Deferred Compensation Plan ("DCP"). The DCP is an unfunded non-qualified deferred compensation plan that permits those certain employees and directors to defer a portion of their compensation to a future time. Eligible employees may elect to defer a portion of their base salary, bonus and/or restricted stock units and eligible directors may defer a portion of their director fees or restricted stock units. All contributions to the DCP on behalf of the participant are fully vested (other than restricted stock unit deferrals which remain subject to the vesting terms of the applicable equity incentive plan) and placed into a grantor trust, commonly referred to as a "rabbi trust." Although we are permitted to make matching contributions under the terms of the DCP, we have not elected to do so. The DCP invests the contributions in diversified securities from a selection of investments and the participants choose their investments and may periodically reallocate the assets in their respective accounts. Participants are entitled to receive the benefits in their accounts upon separation of service or upon a specified date, with benefits payable as a single lump sum or in annual installments. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework. Assets of the rabbi trust, other than Company stock, are recorded at fair value and included in other assets in the condensed consolidated balance sheets. These assets in the rabbi trust are classified as trading securities and changes in their fair values are recorded in other income (loss) in the condensed consolidated statements of comprehensive income (loss). The liability relating to deferred compensation represents our obligation to distribute funds to the participants in the future and is included in other liabilities in the condensed consolidated balance sheets. As of April 2, 2017 , the liability and asset relating to deferred compensation had a fair value of $4.6 million and $4.5 million , respectively. Any unfunded gain or loss relating to changes in the fair value of the deferred compensation liability is recognized in selling, general and administration expense in the condensed consolidated statements of comprehensive income (loss). As of April 2, 2017 , participation in the deferred compensation plan is limited and no restricted stock awards have been deferred into the deferred compensation plan. Stock Appreciation Rights We have granted Stock Appreciation Rights ("SARs") to certain employees under both the 2009 Plan and the 2012 Plan, which entitle the recipient to the appreciation in value of a number of common shares over the exercise price over a period of time, each as specified in the applicable award agreement. The exercise price of any SAR granted may not be less than the fair market value of our common shares on the date of grant. The compensation expense for the SARs is measured based on the fair value of the SARs at the date of grant and is recognized over the requisite service period. The SARs vest over a maximum of three years, have a life of ten years and settle in common shares. We recognize forfeitures of SARs in the period in which they occur. The total fair value of SARs vested was $0.4 million during the three months ended April 2, 2017 . No SARs vested during the three months ended and April 3, 2016 . Three Months Ended April 2, 2017 Stock Appreciation Rights Aggregate Intrinsic Value (in thousands) Weighted Average Exercise Price Average Remaining Contractual Life (Years) Outstanding, beginning of period 790,290 $ 32,659 $ 24.47 4.6 Granted 59,265 77.00 Exercised (181,965 ) 10,846 19.04 Forfeited (9,019 ) 65.21 Outstanding, end of period 658,571 $ 32,339 $ 30.15 5.0 Exercisable, end of period 556,388 $ 31,248 $ 23.09 4.2 Three Months Ended April 3, 2016 Stock Appreciation Rights Aggregate Intrinsic Value (in thousands) Weighted Average Exercise Price Average Remaining Contractual Life (Years) Outstanding, beginning of period 891,147 $ 36,681 $ 20.07 4.9 Granted 121,805 58.37 Exercised (24,443 ) 1,122 15.35 Forfeited (2,400 ) 32.68 Outstanding, end of period 986,109 $ 40,908 $ 24.89 5.4 Exercisable, end of period 679,384 $ 33,765 $ 16.67 4.0 The value of SARs granted in the three months ended April 2, 2017 , as determined using the Black-Scholes Merton valuation model, was $1.3 million and is expected to be recognized over the average requisite service period of 2.0 years. Expected volatility is based upon the historical volatility of our public industry peers’ common shares amongst other considerations. The expected term is calculated using the simplified method, due to insufficient exercise activity during recent years as a basis from which to estimate future exercise patterns. The weighted average grant date assumptions used for the SARs granted were as follows for the periods indicated: 2017 Grants 2016 Grants SAR value (model conclusion) $ 22.65 $ 16.78 Risk-free rate 2.0 % 1.6 % Expected dividend yield 0.0 % 0.0 % Expected volatility 25.8 % 26.2 % Expected term (years) 6.0 6.0 Restricted Stock Units We have granted Restricted Stock Units ("RSUs") to directors and certain employees under both the 2009 Plan and the 2012 Plan. The RSUs confer the right to receive shares of our common stock at a specified future date or when certain conditions are met. The compensation expense for the RSUs awarded is based on the fair value of the RSUs at the date of grant and is recognized over the requisite service period. The RSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted. We recognize forfeitures of RSUs in the period in which they occur. Three Months Ended April 2, 2017 April 3, 2016 Total Restricted Stock Units Outstanding Weighted Average Grant Date Fair Value Total Restricted Stock Units Outstanding Weighted Average Grant Date Fair Value Outstanding, beginning of period 501,926 $ 58.51 526,930 $ 49.31 Granted 226,808 70.60 172,251 57.51 Delivered (176,077 ) (31,120 ) Withheld to cover (1) (54,614 ) (4,745 ) Forfeited (30,664 ) (3,440 ) Outstanding, end of period 467,379 $ 65.72 659,876 $ 50.94 ____________ (1) A portion of the vested RSUs delivered were net share settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting. Approximately one-third of the RSUs granted during the three months ended April 2, 2017 , vest at specified future dates with only service requirements, while the remaining portion of the RSUs vest based on both performance and service requirements. The value of RSUs granted in the three months ended April 2, 2017 , was $16.0 million and is being recognized over the weighted average requisite service period of 2.8 years. During the three months ended April 2, 2017 , there were 230,691 RSUs vested at a fair value of $12.8 million . Warrants On June 9, 2009, we issued 5,833,335 warrants, representing the right to purchase our common shares for $55.31 per share, subsequently adjusted to $50.77 per share for the $4.54 per share return of capital in 2011. Of these, 3,333,334 had an expiration date of June 9, 2014 (the "2014 Warrants"), and 2,500,001 had an expiration date of June 9, 2016 (the "2016 Warrants"). During the six months prior to their respective expiration dates, the warrants provided the holders with a cashless exercise option. There was no activity related to warrants during the three months ended April 2, 2017, and there were no warrants outstanding as of either April 2, 2017, or January 1, 2017. During the three months ended April 3, 2016, holders of the 2016 Warrants exercised 1,076,387 warrants via the cashless option and we issued 108,274 new common shares to the holders. We have accounted for these warrants as equity instruments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases For lease agreements that provide for escalating rent payments or rent-free occupancy periods, we recognize rent expense on a straight line basis over the non-cancelable lease term and any option renewal period where failure to exercise such option would result in an economic penalty in such amount that renewal appears, at the inception of the lease, to be reasonably assured. The lease term commences on the date when all conditions precedent to our obligation to pay rent are satisfied. The leases contain provisions for renewal ranging from zero to three options of generally five years each. Minimum payments, for the following future periods, under non-cancelable operating leases and service agreements with initial or remaining terms of one year or more consist of the following: (In thousands) Fiscal year: 2017 (remaining nine months) $ 16,227 2018 20,404 2019 19,061 2020 16,361 2021 12,453 Thereafter 72,254 Total future minimum lease payments $ 156,760 Total rent expense, including non-cancelable operating leases and month-to-month leases, was $7.1 million and $6.4 million for the three months ended April 2, 2017 , and April 3, 2016 , respectively. We have provided customary indemnifications to our landlords under certain property lease agreements for claims by third parties in connection with their use of the premises. We also have provided routine indemnifications against adverse effects related to changes in tax laws and patent infringements by third parties. The maximum amount of these indemnifications cannot be reasonably estimated due to their nature. In some cases, we have recourse against other parties to mitigate the risk of loss from these indemnifications. Historically, we have not made any significant payments relating to such indemnifications. Legal Proceedings In November 2015, Derrick Byrd, a former hourly employee in California, filed a putative class action lawsuit against us in California Superior Court alleging violations of California wage and hour laws with respect to meal periods and rest breaks and other technical wage and hour issues. In January 2016, we removed the lawsuit to the United States District Court for the Central District of California and on February 25, 2016, the court dismissed the complaint in its entirety. On March 18, 2016, the plaintiff filed an amended complaint, which we moved to dismiss, and we moved to strike several of the plaintiff’s causes of action. On July 7, 2016, the court dismissed several of the plaintiff’s causes of action and gave the plaintiff leave to amend. On July 29, 2016, the plaintiff filed a second amended complaint containing a narrower version of nine of the eleven original claims. We answered this amended complaint on August 12, 2016, and amended our answer on September 14, 2016. On November 28, 2016, the plaintiff filed a third amended complaint to add an additional individual as a plaintiff. On December 19, 2016, we answered this amended complaint. The plaintiffs continue to allege violations with respect to overtime pay, meal periods, rest breaks, minimum wage, timely pay, wage statement detail and reimbursement of business expenses. The lawsuit seeks damages, penalties, attorney’s fees and an award under the California Private Attorney General Act. Discovery is underway. The court has set the deadline for the plaintiff to file his motion for class certification for August 21, 2017, and the trial date has been set for November 28, 2017, although those dates may be extended. The parties have engaged in preliminary settlement negotiations and a mediation session is scheduled to be held in May 2017. While we intend to defend the lawsuit vigorously, there can be no assurance that the ultimate resolution of this lawsuit will not have a material, adverse effect on our consolidated financial condition or results of operations. In addition, from time to time, we are involved in various claims, legal actions and government audits. In the opinion of management, the ultimate disposition of these matters, individually and in the aggregate, will not have a material effect on our financial condition, results of operations or cash flows.

The 2016 Plan is expected to improve our cost structure and enhance operational efficiencies, and is expected to be completed by the end of the third quarter of 2017. Costs associated with the 2016 Plan include closure costs and severance. As of April 2, 2017 , we expect to incur approximately $2.2 million of additional charges related to the 2016 Plan. Our restructuring plans initiated in 2015 and prior years are described in detail in our Annual Report on Form 10-K for the year ended January 1, 2017. Costs associated with the 2015, 2014, 2013 and 2012 and Prior Plans include severance and closure charges and are substantially completed. The 2013 Plan also included impairment of certain property, plant and equipment. The 2012 and Prior Plans are substantially completed, although cash payments are expected to continue through 2019, primarily related to lease payments at closed facilities. As of April 2, 2017 , we do not expect to incur any material future charges relating to the 2015 Plan, the 2013 Plan or the 2012 and Prior Plans and, pending the ultimate resolution of the Stay of Proceedings, we do not anticipate any material future charges related to the 2014 Plan.

Segment Reporting [Abstract]
Segment Information	Segment Information Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The North American Residential reportable segment is the aggregation of the Wholesale and Retail operating segments. The Europe reportable segment is the aggregation of the United Kingdom and Central Eastern Europe operating segments. The Architectural reportable segment consists solely of the Architectural operating segment. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments which were not aggregated into any reportable segment. Operating segments are aggregated into reportable segments only if they exhibit similar economic characteristics. In addition to similar economic characteristics we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors. Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or operating cash flows determined in accordance with GAAP. Adjusted EBITDA is defined as net income (loss) attributable to Masonite adjusted to exclude the following items: • depreciation; • amortization; • share based compensation expense; • loss (gain) on disposal of property, plant and equipment; • registration and listing fees; • restructuring costs; • asset impairment; • loss (gain) on disposal of subsidiaries; • interest expense (income), net; • loss on extinguishment of debt; • other expense (income), net; • income tax expense (benefit); • loss (income) from discontinued operations, net of tax; and • net income (loss) attributable to non-controlling interest. This definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indenture governing the 2023 Notes and the credit agreement governing the ABL Facility. Adjusted EBITDA is used to evaluate and compare the performance of the segments and it is one of the primary measures used to determine employee incentive compensation. Intersegment transfers are negotiated on an arm’s length basis, using market prices. Certain information with respect to segments is as follows for the periods indicated: (In thousands) Three Months Ended April 2, 2017 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 339,129 $ 70,827 $ 75,919 $ 7,341 $ 493,216 Intersegment sales (1,087 ) (856 ) (4,092 ) — (6,035 ) Net sales to external customers $ 338,042 $ 69,971 $ 71,827 $ 7,341 $ 487,181 Adjusted EBITDA $ 44,937 $ 7,674 $ 5,214 $ (4,966 ) $ 52,859 (In thousands) Three Months Ended April 3, 2016 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 330,616 $ 80,607 $ 76,309 $ 6,473 $ 494,005 Intersegment sales (1,887 ) (16 ) (2,797 ) — (4,700 ) Net sales to external customers $ 328,729 $ 80,591 $ 73,512 $ 6,473 $ 489,305 Adjusted EBITDA $ 51,375 $ 10,118 $ 4,431 $ (7,683 ) $ 58,241 A reconciliation of our consolidated Adjusted EBITDA to net income (loss) attributable to Masonite is set forth as follows for the periods indicated: Three Months Ended (In thousands) April 2, 2017 April 3, 2016 Adjusted EBITDA $ 52,859 $ 58,241 Less (plus): Depreciation 14,024 14,570 Amortization 5,970 6,464 Share based compensation expense 2,427 3,728 Loss (gain) on disposal of property, plant and equipment (274 ) 132 Restructuring costs 293 19 Interest expense (income), net 7,024 7,232 Other expense (income), net (249 ) 786 Income tax expense (benefit) (1,679 ) 6,210 Loss (income) from discontinued operations, net of tax 245 188 Net income (loss) attributable to non-controlling interest 1,513 1,084 Net income (loss) attributable to Masonite $ 23,565 $ 17,828

Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, income taxes receivable, accounts payable, accrued expenses and income taxes payable approximate fair value because of the short-term maturity of those instruments. The estimated fair value of the 2023 Notes as of April 2, 2017 , and January 1, 2017 , was $478.1 million and $485.4 million , respectively, compared to a carrying value of $469.8 million and $469.6 million , respectively. This estimate is based on market quotes and calculations based on current market rates available to us and is categorized as having Level 2 valuation inputs as established by the FASB’s Fair Value Framework. Market quotes used in these calculations are based on bid prices for our debt instruments and are obtained from and corroborated with multiple independent sources. The market quotes obtained from independent sources are within the range of management’s expectations.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share ("EPS") is calculated by dividing earnings attributable to Masonite by the weighted-average number of our common shares outstanding during the period. Diluted EPS is calculated by dividing earnings attributable to Masonite by the weighted-average number of common shares plus the incremental number of shares issuable from non-vested and vested RSUs, SARs and warrants outstanding during the period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entity	Variable Interest Entity As of April 2, 2017 , and January 1, 2017 , we held an interest in one variable interest entity ("VIE"), Magna Foremost Sdn Bhd, which is located in Bintulu, Malaysia. The VIE is integrated into our supply chain and manufactures door facings. We are the primary beneficiary of the VIE via the terms of the existing operating principles with the VIE. As primary beneficiary via the operating principles, we receive a disproportionate amount of earnings on sales to third parties in relation to our voting interest, and as a result, receive a majority of the VIE’s residual returns. Sales to third parties did not have a material impact on our condensed consolidated financial statements. We also have the power to direct activities of the VIE that most significantly impact the entity’s economic performance. As its primary beneficiary, we have consolidated the results of the VIE. Our net cumulative investment in the VIE was comprised of the following as of the dates indicated: (In thousands) April 2, January 1, Current assets $ 9,041 $ 6,633 Property, plant and equipment, net 13,228 13,673 Long-term deferred income taxes 6,550 6,505 Other assets, net 1,932 1,789 Current liabilities (2,275 ) (2,044 ) Other long-term liabilities (2,143 ) (2,115 ) Non-controlling interest (5,260 ) (4,664 ) Net assets of the VIE consolidated by Masonite $ 21,073 $ 19,777 Current assets include $4.9 million and $2.6 million of cash and cash equivalents as of April 2, 2017 , and January 1, 2017 , respectively. Assets recognized as a result of consolidating this VIE do not represent additional assets that could be used to satisfy claims against our general assets. Furthermore, liabilities recognized as a result of consolidating these entities do not represent additional claims on our general assets; rather, they represent claims against the specific assets of the consolidated VIE.

Accounting Policies [Abstract]
New Accounting Pronouncements	Adoption of Recent Accounting Pronouncements In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-11, "Simplifying the Measurement of Inventory," which amended ASC 330, "Inventory." This ASU requires the measurement of inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years; early adoption is permitted. The adoption of this standard did not have a material impact on the presentation of our financial statements. Other Recent Accounting Pronouncements not yet Adopted In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which amends ASC 715, “Retirement Benefits”. This ASU requires disaggregation of the service cost component from the other components of net benefit cost. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years; early adoption is permitted and retrospective application is required. We are in the process of evaluating this guidance to determine the impact it may have on our financial statements. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment", which amends ASC 350 "Intangibles - Goodwill and Other". This ASU simplifies the accounting for goodwill impairments and allows a goodwill impairment charge to be based upon the amount of a reporting unit's carrying value in excess of its fair value; thus, eliminating what is currently known as "Step 2" under the current guidance. This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods; early adoption is permitted and prospective application is required. We are in the process of evaluating this guidance to determine the impact it may have on our financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers - Deferral of the Effective Date," and the guidance will now be effective for annual and interim periods beginning on or after December 15, 2017; early application is permitted only as of annual and interim reporting periods beginning after December 15, 2016. While we are still in the process of evaluating the effect of adoption on our consolidated financial statements and are currently assessing our contracts with customers, we do not currently expect the adoption of the new standard to have a material impact on consolidated net income (loss) attributable to Masonite, cash flows or our consolidated balance sheets. We plan to adopt this standard using the retrospective method and adoption will be effective as of January 1, 2018.
