Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations and Basis of Presentation	1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION Nature of Operations Duluth Holdings Inc. (“Duluth Trading” or the “Company”), a Wisconsin corporation, is a lifestyle brand of men’s and women’s casual wear, workwear and accessories sold exclusively through the Company’s own direct and retail channels. The direct segment, consisting of the Company’s website and catalogs, offers products nationwide. In 2010, the Company added retail to its omnichannel platform with the opening of its first store. Since then, Duluth Trading has expanded its retail presence, and as of January 28, 2018, the Company operated 28 retail stores and three outlet stores. The Company’s products are marketed under the Duluth Trading Company brand, with the majority of products being exclusively developed and sold as Duluth Trading branded merchandise. The Company has two classes of authorized common stock: Class A common stock and Class B common stock. The rights of holders of Class A common stock and Class B common stock are identical, except for voting and conversion rights. Each share of Class A common stock is entitled to ten votes per share and is convertible at any time into one share of Class B common stock. Each share of Class B common stock is entitled to one vote per share. The Company’s Class B common stock trades on the NASDAQ Global Select Market under the symbol “DLTH.” On November 25, 2015, the Company converted from an “S” corporation to a “C” corporation for federal income tax purposes under Section 1362 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Company completed its initial public offering (“IPO”). The Company issued and sold 7,666,667 shares of its Class B common stock, which includes 1,000,000 shares of Class B common stock issued pursuant to the underwriters’ option to purchase additional shares, at a price of $ 12.00 per share, less the underwriting discount. The Company received net proceeds of approximately $ 83.9 million after deducting the underwriting discount of $ 6.4 million and related fees and expenses of approximately $ 1.7 million. The Company used $ 46.6 million of the net proceeds from the IPO to pay the total final distribution of 100% of the cumulative undistributed taxable earnings to its then existing shareholders from the date of its formation through the date of termination of its “S” corporation status. Basis of Presentation The consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). All intercompany balances and transactions have been eliminated. The Company’s fiscal year ends on the Sunday nearest to January 31 of the following year. Fiscal 2017, 2016 and 2015 ended on January 28, 2018, January 29, 2017, and January 31, 2016, respectively, and were all 52-week periods. Seasonality of Business The Company’s business is affected by the pattern of seasonality common to most retail apparel businesses. Historically, the Company has recognized a significant portion of its revenue and operating profit in the fourth fiscal quarter of each year as a result of increased sales during the holiday season. Unaudited Pro Forma Net Income Information For the year ended January 31, 2016, the unaudited pro forma net income information gives effect to the conversion of the Company to a “C” corporation on November 25, 2015. Prior to such conversion, the Company was an “S” corporation and generally not subject to income taxes. The pro forma net income, therefore, includes an adjustment for income tax expense on the income attributable to controlling interest as if the Company had been a “C” corporation as of February 4, 2013 at an assumed combined federal, state and local effective tax rate of 40% , which approximates the calculated statutory rate for each period. No pro forma income tax expense was calculated on the income attributable to noncontrolling interest because this entity did not convert to a “C” corporation. For the year ended January 31, 2016, the unaudited pro forma basic and diluted net income per share of Class A and Class B common stock is computed using the unaudited pro forma net income, as discussed above.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The accompanying consolidated financial statements include the accounts of the parent, Duluth Holdings Inc., and its wholly-owned subsidiary, Duluth Trading Company, LLC. Effective October 3, 2016, Duluth Trading Company, LLC was dissolved and no longer consolidated, which did not impact the Company’s consolidated financial statements. The Company also consolidates Schlecht Retail Ventures LLC (“SRV”) as a variable interest entity (see Note 5 “Variable Interest Entities”). Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition The Company recognizes revenue when the following four criteria are met: · persuasive evidence of an arrangement exists; · title has passed to the customer; · the sales price is fixed and determinable and no further obligation exists; and · collectability is reasonably assured. These criteria are met upon customer receipt of the product (for direct sales) or at the point of sale (for retail store transactions). At the time of revenue recognition, the Company provides for estimated costs that may be incurred for product warranties and sales returns. A liability is recognized at the time a gift card is sold, and revenue is recognized at the time the gift card is redeemed for merchandise. Cost of Goods Sold and Selling, General and Administrative Expenses The following table illustrates the primary costs classified in cost of goods sold and selling, general and administrative expenses:     Cost of Goods Sold Selling, General and Administrative Expenses   Direct cost of purchased merchandise  Payroll and payroll-related expenses   Inventory shrinkage and inventory adjustments due to obsolescence  Third party logistics ("3PL")   Inbound freight  Occupancy expenses related to stores and operations at the Company's headquarters, including utilities   Freight from the Company's distribution centers to its stores  Depreciation and amortization   Advertising expenses, including television advertising, catalog production and mailing and print advertising costs   Freight associated with shipping product to customers   Consulting and professional fees Deferred Catalog and Advertising Expenses The Company’s direct-response advertising consists of producing, printing and mailing catalogs, which are capitalized as deferred catalog costs and amortized over the expected term of the related revenue stream (generally three to five months from the date catalogs are mailed). The Company’s non-direct response advertising costs are expensed as they are incurred. Non-direct response advertising costs primarily consist of billboards, web marketing programs, and radio and television advertisements. Catalog and advertising expenses were $ 88.6 million, $78.5 million and $65.2 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively. Shipping and Processing Shipping and processing revenue generated from customer orders has been classified as a component of net sales. Shipping and processing expense, including handling expense, has been classified as a component of selling, general and administrative expenses. The Company incurred shipping and processing expenses of $ 28.1 million, $24.3 million and $20.4 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively. Income Taxes Prior to November 25, 2015, the Company was taxed as an “S” corporation for income tax purposes under section 1362 of the Code, and therefore was not subject to federal and state income taxes. On November 25, 2015, the Company’s “S” corporation status terminated and the Company became subject to corporate-level federal and state income taxes at prevailing corporate rates. As a result of the conversion, effective November 25, 2015, the Company accounts for income taxes and related accounts using the liability method in accordance with ASC Topic 740, Income Taxes (“ASC 740”). Under ASC 740, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between U.S. GAAP and tax bases of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted tax rates in effect for the years in which the differences are expected to reverse, and recognizes the effect of a change in enacted rates in the period of enactment. A valuation allowance is established if it is more likely than not that some portion or all of the deferred income tax asset will not be realized. The Company establishes assets and liabilities for uncertain tax positions taken or expected to be taken in income tax returns, using a more-likely-than-not recognition threshold. The Company recognizes penalties and interest related to uncertain tax positions as income tax expense. See Note 8 “Income Taxes,” of these Notes to Consolidated Financial Statements for further discussion. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. At various times during the year, the Company has certain cash balances deposited in financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes it is not exposed to any significant credit risk. Restricted Cash The Company’s restricted cash is held in an escrow account and is used to pay some portion of the construction loans entered into by the third party landlords (the “Landlords”) in connection with some of the Company’s retail store leases. The restricted cash is disbursed based on the escrow agreement entered into by and among the Landlords, the Company and the escrow agent. Significant Suppliers The Company’s principal supplier of inventory accounted for 50% , 51% and 54% of total inventory expenditures in fiscal 2017, fiscal 2016 and fiscal 2015, respectively. The Company also had a second supplier that accounted for 18% , 21% and 17% of total inventory expenditures in fiscal 2017, fiscal 2016 and fiscal 2015, respectively. Inventory Valuation Inventory, consisting of purchased product, is valued at the lower of cost and net realizable value, under the first-in, first-out method. Property and Equipment Property and equipment consist of the following:      January 28, 2018 January 29, 2017  (in thousands)  Land and land improvements $ 3,055 $ 2,986  Leasehold improvements 20,985 12,752  Buildings 33,906 16,178  Vehicles 177 177  Warehouse equipment 5,850 3,939  Office equipment and furniture 22,161 11,125  Computer equipment 3,573 2,509  Software 7,540 6,659  97,247 56,325  Accumulated depreciation and amortization (22,739) (15,529)  74,508 40,796  Construction in progress 35,197 11,636  Property and equipment, net $ 109,705 $ 52,432  The Company recorded depreciation expense of $ 7.3 million, $ 4.6 million and $ 2.8 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively. The Company expenses all routine repair and maintenance costs that do not extend the estimated useful life of the asset. Property and equipment are carried at cost and are generally depreciated using the straight-line method over the estimated useful lives. Leasehold improvements are depreciated over the shorter of the lease term or estimated useful life. Depreciable lives by major classification are as follows:      Years  Land improvements 15 - 40  Leasehold improvements 3 - 15  Buildings 39  Vehicles 5 - 10  Warehouse equipment 5 - 15  Office equipment and furniture 3 - 10  Computer equipment 3 - 5  Software 3 - 5  Build-to-Suit Lease The Company may at times be involved in the construction of stores to be leased by the Company and, depending on the extent to which the Company is involved, the Company may be deemed the owner of the leased premises for accounting purposes during the store construction period. For leases that the Company is deemed the owner of the property during the construction period, upon commencement of the construction project, the Company is required to capitalize the cash and non-cash assets contributed by the landlord for construction as property and equipment on the Company’s Consolidated Balance Sheets. Upon the completion of the construction project, the Company performs an analysis on the lease to determine if the Company qualifies for sale-leaseback treatment. For those qualifying leases, the finance lease obligation and the associated property and equipment are removed and the difference is reclassified to either prepaid or deferred rent and amortized over the lease term as an increase or decrease to rent expense. If the lease does not qualify for sale-leaseback treatment, the finance lease obligation is amortized over the lease term based on the rent payments in the lease agreement and the associated property and equipment are depreciated over the estimated useful life. As of January 28, 2018, and January 29, 2017, the Company capitalized $36.5 million and $6.6 million in property and equipment, respectively, and $0.3 million and $0.01 million in accumulated depreciation, respectively, and recorded a $26.6 million and a $3.3 million non-current liability, respectively, related to build-to-suit lease transactions in which the Company is considered the owner for accounting purposes. Goodwill Goodwill represents the excess of purchase price over the fair value of net assets acquired. ASC Topic 350, Intangibles-Goodwill and Other , requires that goodwill be tested for impairment annually, or more often if an event or circumstance indicates that an impairment loss may have been incurred. The Company’s management uses its judgment in assessing whether goodwill may have become impaired between annual impairment tests. Indicators such as unexpected adverse business conditions, economic factors, competitive activities, loss of key personnel and acts by governments may signal that an asset has become impaired. Total goodwill is reported in the Company’s direct segment. Management performed a qualitative assessment of goodwill as of December 31, 2017, 2016 and 2015, and determined that it was more likely than not that the fair value of the Company was greater than its carrying amount; as such, no further evaluation of goodwill was deemed necessary. No impairment was recognized for the years ended January 28, 2018, January 29, 2017, or January 31, 2016. Other Assets Other assets include loan origination fees, trade names and other non-current assets which are amortized over their estimated useful lives ranging from three to fifteen years. Other assets also include security deposits required by certain of the Company’s lease agreements and prepaid expenses which are not expected to be amortized within the next 12 months. Amortization expense was $0.1 million for each fiscal 2017, fiscal 2016 and fiscal 2015. Accumulated amortization was $0.3 million and $0.2 million as of January 28, 2018 and January 29, 2017, respectively. Scheduled future amortization of amortizable other assets are as follows as of January 28, 2018:      Fiscal year  (in thousands)  2018 $ 29  2019 26  2020 22  2021 21  2022 20  Thereafter 80  $ 198  Impairment of Long-Lived Assets The Company’s long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and the carrying value of the asset or group of assets. Such analyses necessarily involve judgment. For fiscal 2017, fiscal 2016 and fiscal 2015, management did not identify any events or changes in circumstances that indicated the potential impairment of long-lived assets. Deferred Rent Obligation Certain of the Company’s operating lease agreements contain provisions for future rent increases, a rent free period, and/or a period in which rental payments are reduced (abated). For each such agreement, the total amount of rental payments due over the lease term is being charged to rent expense on the straight-line method over the term of the lease. The difference between rent expense recorded and the amount paid is charged to deferred rent obligations, the current portion of which is included in accrued other expenses in the consolidated balance sheets. Store Pre-opening Costs Store pre-opening costs are expensed as incurred and are included in selling, general and administrative expenses. Stock-Based Compensation In connection with the IPO, the Company adopted the 2015 Equity Incentive Plan of Duluth Holdings Inc. (“2015 Plan”), which provides compensation alternatives such as stock options, shares, restricted stock, restricted stock units, deferred stock and performance share units, using or based on the Company’s Class B common stock. At the time of adoption, the Company reserved 1,614,631 shares of Class B common stock for the issuance of awards under the 2015 Plan. On the first day of the first four fiscal years following the IPO, the number of shares reserved for future issuance under the 2015 Plan will increase by 1.25% of the number of Class A and Class B common stock outstanding on the last day of the immediately preceding fiscal year. On January 29, 2018, the number of Class B common stock available for future issuance under the 2015 Plan was 2,653,439 shares. The Company accounts for its stock-based compensation plan in accordance with ASC Topic 718, Stock Compensation , which requires the Company to measure all share-based payments at grant date fair value and recognize the cost over the requisite service period of the award. Restricted stock issued to board members generally vests over a period of one year. Restricted stock issued to key employees and executives typically vests over a period of two to five years based on the terms for each individual award. The fair value of the restricted stock is determined based on the market value of the Company’s Class B common stock on the grant date. Restricted stock forfeitures are recognized as incurred. For restricted stock awards granted prior to the Company’s IPO, the fair value of the Company’s Class B common stock was calculated by an independent third party and was estimated by taking the average of the results of applying discounted cash flow and market comparable analyses. This value was then discounted due to the lack of marketability and liquidity of the restricted stock. Total stock compensation expense associated with restricted stock recognized by the Company was $ 1.6 million, $1.2 million and $0.7 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively, and is included in selling, general and administrative expenses on the Consolidated Statements of Operations. The following is a summary of the activity in the Company’s non-vested restricted stock during the years ended January 28, 2018, January, 29, 2017, and January 31, 2016:      Weighted average  grant date  fair value  Shares per share  Outstanding at February 1, 2015 246,708 $ 1.67  Granted 587,769 3.78  Vested (38,124) 3.35  Outstanding at January 31, 2016 796,353 3.15  Granted 59,814 23.41  Vested (61,455) 7.52  Outstanding at January 29, 2017 794,712 4.34  Granted 110,878 19.54  Vested (347,825) 3.04  Forfeited (21,294) 22.31  Outstanding at January 28, 2018 536,471 $ 7.60  At January 28, 2018, the Company had unrecognized compensation expense of $ 2.1 million related to the restricted stock awards, which is expected to be recognized over a weighted average period of 1.8 years. Taxes Collected from Customers The Company presents all non-income government-assessed taxes (sales, use and value-added taxes) collected from its customers and remitted to governmental agencies on a net basis (excluded from revenue) in its consolidated financial statements. Other Comprehensive Income or Loss Other comprehensive income or loss represents the change in equity from non-shareholder or non-member transactions, which is not included in the statements of earnings but is reported as a separate component of shareholders’ equity. For fiscal 2016 and fiscal 2015, other comprehensive income or loss consists of changes in the fair value of the Company’s interest rate swap agreements. Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) , defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date (i.e., an exit price). The exit price is based on the amount that the holder of the asset or liability would receive or need to pay in an actual transaction (or in a hypothetical transaction if an actual transaction does not exist) at the measurement date. ASC 820 describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable, as follows: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying values of cash, accounts receivable, accounts payable and long-term obligations approximate fair value. The carrying value of goodwill and intangible assets are tested annually, or more frequently if an event occurs that indicates an impairment loss may have been incurred, using fair value measurements with unobservable inputs (Level 3). The carrying value of the Company's available-for-sale security was valued based on a discounted cash flow method (Level 3).

Variable Interest Entities [Abstract]
Variable Interest Entities	5. VARIABLE INTEREST ENTITIES Based upon the criteria set forth in ASC 810, Consolidation , the Company has determined that it was the primary beneficiary of one variable interest entity (“VIE”) as of January 28, 2018 and January 29, 2017, as the Company absorbs significant economics of the entity and has the power to direct the activities that are considered most significant to the entity. The Company leases certain retail store facilities and office buildings from SRV, a VIE whose primary purpose and activity is to own this real property. SRV is a Wisconsin limited liability company that is owned by the majority shareholder of the Company. The Company considers itself the primary beneficiary for SRV as the Company is expected to receive a majority of SRV’s expected residual returns based on the activity of SRV. As the Company is the primary beneficiary, it consolidates SRV and the leases are eliminated in consolidation. The consolidated balance sheets include the following amounts as a result of the consolidation of SRV:      January 28, 2018 January 29, 2017  (in thousands)  Cash $ 655 $ 139  Other receivables 10 9  Property and equipment, net 4,114 3,248  Other assets, net 53 5  Total assets $ 4,832 $ 3,401   Other current liabilities $ 160 $ 792  Long-term debt 1,393 —  Noncontrolling interest in VIE 3,279 2,609  Total liabilities and shareholders' equity $ 4,832 $ 3,401  The real property owned by SRV is collateral for SRV’s 2017 Notes (see Note 3 “Debt and Lines of Credit”).  On August 18, 2017, the Company entered into a lease agreement with TRI Holdings, LLC (“TRI”), the developer of the Company’s future headquarters in Mt. Horeb, Wisconsin. The Company expects to take occupancy of the future headquarters on November 1, 2018. The Company determined it had a variable interest in TRI, however, the Company does not consolidate TRI, as the Company is not the primary beneficiary. In conjunction with the lease, the Company invested $6.3 million in a trust (see Note 2 Summary of Significant Accounting Policies under the header Fair Value Measurements ) that loaned funds to TRI for the construction of the Company’s future headquarters. The Company does not consolidate the trust as the Company is not the primary beneficiary.  T he Company does not consolidate Schlech t Port Washington LLC (“SPW”) because the Company is not the primary beneficiary.

Segment Reporting [Abstract]
Segment Reporting	7. SEGMENT REPORTING The Company has two operating segments, which are also its reportable segments: direct and retail. The direct segment includes revenues from the Company’s website and catalogs. The retail segment includes revenues from the Company’s retail and outlet stores. These two operating segments are components of the Company for which separate financial information is available and for which operating results are evaluated on a regular basis by the chief operating decision maker in deciding how to allocate resources and in assessing performance of the segments. Income tax expense, and corporate expenses, which include but are not limited to: human resources, legal, finance, information technology, design and other corporate related expenses, are included in the Company’s direct segment. Interest expense, depreciation and amortization, and property and equipment expenditures, are recognized in each respective segment. Advertising expenses are generally included in the Company’s direct segment, except for specific store advertising, which is included in the Company’s retail segment. Net sales by product is not presented because providing the information is impracticable. Net sales outside of the United States were insignificant. Variable allocations of assets are not made for segment reporting. The Company does not have any assets outside of the United States.

Income Taxes [Abstract]
Income Taxes	8. INCOME TAXES On November 25, 2015, the Company’s “S” corporation status terminated and the Company became subject to corporate-level federal and state income taxes at prevailing corporate rates. On December 22, 2017, the United States enacted significant changes to the U.S. tax law following the passage and signing of H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Tax Act”) (previously known as “The Tax Cuts and Jobs Act”). The Tax Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the corporate tax rate from 35% to 21% . The permanent reduction to the U.S. federal corporate income tax rate from 35% to 21% is effective January 1, 2018 (the “Effective Date”). When a U.S. federal tax rate change occurs during a fiscal year, taxpayers are required to compute a weighted daily average rate for the fiscal year of enactment. As a result of the Tax Act, the Company has calculated a U.S. federal statutory corporate income tax rate of 33.9% for the fiscal year 2017. The U.S. federal statutory corporate income tax rate of 33.9% is the weighted daily average rate between the pre-enactment U.S. federal statutory tax rate of 35% applicable to the Company’s current fiscal year prior to the Effective Date and the post-enactment U.S. federal statutory tax rate of 21% applicable from January 1 to January 28 of 2018. The Company expects the U.S. federal statutory rate to be 21% for fiscal years beginning after January 28, 2018. On December 22, 2017, the SEC issued Staff Accounting Bulletin 118 (“SAB 118”). SAB 118 expresses views of the staff of the SEC regarding ASC Topic 740, Income Taxes (“ASC 740”) in the reporting period that includes the enactment date of the Tax Act. The SEC staff issuing SAB 118 (the “Staff”) recognized that a registrant’s review of certain income tax effects of the Tax Act may be incomplete at the time financial statements are issued for the reporting period that includes the enactment date, including interim periods therein. The Staff’s view of the enactment of the Tax Act has been developed considering the principles of ASC Topic 805, Business Combinations, which addresses the accounting for certain items in a business combination for which the accounting is incomplete upon issuance of the financial statements that include the reporting period in which the business combination occurs. Specifically, the Staff provides that the accounting guidance in ASC Topic 805 may be analogized to the accounting for impacts of the Tax Act. If a company does not have the necessary information available, prepared or analyzed for certain income tax effects of the Tax Act, SAB 118 allows a company to report provisional numbers and adjust those amounts during the measurement period not to extend beyond one year. For the year ended January 28, 2018, the Company has recorded all known and estimable impacts of the Tax Act that are effective for fiscal year 2017. Future adjust ments will be recorded as discrete adjustments to income tax expense in the period in which those adjustments become estimable and/or are finalized. Accordingly, the Company’s income tax provision as of January 28, 2018 reflects (i) the current year impacts of the Tax Act on the estimated annual effective tax rate and (ii) the following discrete items resulting directly from the enactment of the Tax Act based on the information available, prepared, or analyzed (including computations) in reasonable detail. The net benefit on U.S. deferred tax assets and liabilities for the year ended January 28, 2018 was $1.5 million. The components of income tax expense were as follows:     Fiscal Year Ended    January 28, 2018 January 29, 2017 January 31, 2016  (in thousands)  Current:  Federal $ 9,118 $ 10,009 $ 1,114  State 2,227 1,980 194  11,345 11,989 1,308  Deferred:  Federal 658 1,496 100  State (125) 40 (69)  533 1,536 31  Total income tax expense $ 11,878 $ 13,525 $ 1,339  The reconciliation of income tax expense to the amount computed at the federal statutory rate was as follows:     Fiscal Year Ended   January 28, 2018 January 29, 2017 January 31, 2016  (in thousands)  Federal taxes at statutory rate $ 11,939 33.9 % $ 12,194 35.0 % $ 10,073 35.0 %  Tax effect of earnings not subject to federal income tax due to "S" corporation status — — % — — % (8,952) (31.1) %  Statutory rate change (1,510) (4.3) % — — % — — %  State and local income taxes, net of federal benefit 1,410 4.0 % 1,315 3.8 % 124 0.4 %  Impact of change in tax status — — % — — % 94 0.3 %  Other 39 0.1 % 16 0.1 % — — %  Total income tax expense $ 11,878 33.7 % $ 13,525 38.9 % $ 1,339 4.6 %   As a result of the conversion to a “C” corporation, the Company recorded an increase in net deferred tax liabilities of $ 0.1 million and a one-time deferred tax expense of $ 0.1 million during the fourth quarter of fiscal 2015. Deferred income taxes reflect the net tax effects of temporary differences between U.S. GAAP and tax bases of assets and liabilities. Significant components of deferred tax assets and liabilities were as follows:      January 28, 2018 January 29, 2017  (in thousands)  Deferred tax assets:  Returns allowance $ 281 $ 424  Uniform capitalization 723 754  Inventory 485 484  Deferred rent 935 902  Accruals 7,902 2,128  Stock-based compensation 158 —  Advance payments 386 267  Total deferred tax assets 10,870 4,959   Deferred tax liabilities:  Property and equipment 12,174 5,130  Stock-based compensation — 227  Prepaid expenses 734 1,069  Goodwill and intangibles 62 100  Total deferred tax liabilities 12,970 6,526  Net deferred tax liabilities $ 2,100 $ 1,567  Uncertain Tax Positions As of January 28, 2018 and January 29, 2017, there were no material unrecognized tax benefits. The Company does not anticipate that there will be a material change in the balance of the unrecognized tax benefits in the next 12 months. Any interest and penalties related to uncertain tax positions are recorded in income tax expense. There were no amounts recorded as tax expense for interest or penalties for the years ended January 28, 2018, January 29, 2017, and January 31, 2016. The Company files income tax returns in the United States federal jurisdiction and in various state jurisdictions. Federal tax returns for tax years beginning January 1, 201 4 , and state tax returns for tax years beginning January 1, 201 3 , are open for examination.

Leases [Abstract]
Leases	9. LEASES The Company is party to non-cancellable operating leases. Store leases generally have initial lease terms ranging from five to fifteen years with renewal options on substantially the same terms and conditions as the original leases. The Company leases retail space in Port Washington, Wisconsin, from SPW, which is owned by the majority shareholder of the Company. The lease expires in December 2023 and is accounted for as an operating lease. The Company has the option to renew the lease for one additional five -year period under substantially the same terms. The lease provides for base monthly payments of $ 10,600 beginning in October 2013 and effective January 2015, monthly payments increase by 2 % annually. As of January 28, 2017, the base monthly payment was $ 11,500 . Rental expense was $ 0.1 million for fiscal 2017, fiscal 2016 and fiscal 2015.

Commitments And Contingencies	12. COMMITMENTS AND CONTINGENCIES From time to time, the Company becomes involved in lawsuits and other claims arising from its ordinary course of business. Because of the uncertainties related to the incurrence, amount and range of loss on any pending litigation or claim, management is currently unable to predict the ultimate outcome of any litigation or claim, determine whether a liability has been incurred or make an estimate of the reasonably possible liability that could result from an unfavorable outcome. Management believes, after considering a number of factors and the nature of any outstanding litigation or claims, that the outcome will not have a material effect upon the Company’s results of operations, financial condition or cash flows. However, because of the unpredictable nature of these matters, the Company cannot provide any assurances regarding the outcome of any litigation or claim to which it is a party or the impact on it of an adverse ruling in such matters.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	14. RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements Simplifying the Measurement of Inventory In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (Topic 330) (“ASU 2015-11”), which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. Net realizable value is defined as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.” ASU 2015-11 eliminates the guidance that entities consider replacement cost or net realizable value less an approximately normal profit margin in the subsequent measurement of inventory when cost is determined on a first-in, first-out or average cost basis. The provisions of ASU 2015-11 are effective for public entities with fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2015-11 as of January 30, 2017, the first day of the Company’s fiscal year 2017, and there was no significant impact to the Company’s consolidated financial statements.        Recently Issued Accounting Pronouncements Not Yet Adopted Revenue from Contracts with Customers In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition . ASU 2014-09 requires revenue recognition to depict the transfer of 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. The new revenue recognition model requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of the performance obligations. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and change s in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 can be applied either on a retrospective basis to each prior reporting period presented or a modified retrospective basis with th e cumulative effect of initial adoption reflected as an adjustment to open retained earnings. On July 9, 2015, the FASB deferred the effective date of ASU 2014-09 for one year. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017. Accordingly, the Company adopted ASU 2014-09 on January 29, 2018, the first day of the Company’s first quarter for the fiscal year ending February 3, 2019, the Company’s fiscal year 2018 . The Company adopted ASU 2014-09 on a modified retrospective basis . Based on the Company’s analysis to date, the Company expects a change in revenue recognition for its direct sales , such that, revenues on direct sales will be recognized upon shipment as opposed to current recognition upon delivery. Revenue recognition relative to retail sales is not expected to vary from current recognition. The Company expects to expense the cost of catalogs upon mailing as opposed to deferring the cost and amortizing the expense over a three to five month period. Finally, the Company expects its balance sheet will be grossed up to present an asset for recovery, separately from inventory and a refund liability related to sales returns. The Company continues to evaluate the new disclosure requirements of ASU 2014-09 on its consolidated financial statements. Financial Instruments In January 2016, the FASB issued Accounting Standards Update No. 2016-01 , Financial Instruments (Subtopic 825-10) ( “ ASU 2016-01 ”), which amends various aspects of the recognition, measurement, presentation, and disclosure for financial instr uments. T he most significant impact relates to the accounting for equity investments. ASU 2016-01 will impact the disclosure and presentation of financial assets and liabilities. ASU 2016-01 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017, accordingly, the Company adopted ASU 2016-01 on January 29, 2018. The Company is currently in the process of evaluating the impact of the adoption of this standard on our consolidated financial statements. Leases In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to recognize most leases on the balance sheets (right-of-use asset and lease liability), but recognize expenses on the income statements in a manner which is similar to the current lease standard. The provisions of ASU 2016-02 are effective for public entities with fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. The Company expects to adopt ASU 2016-02 on February 4, 2019, the first day of the Company’s first quarter for the fiscal year ending February 2, 2020, the Company’s fiscal year 2019. The Company conducts its retail operations through leased stores and therefore, the Company expects the adoption of ASU 2016-02 to have an increase in assets and liabilities on the Company’s Consolidated Balance Sheets, due to recording of right-to-use assets and the corresponding lease liabilities, which is expected to be material. Statement of Cash Flows In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230 ): Restricted Cash (“ASU 2016-18”), which requires companies to include cash and cash equivalents that have restrictions on withdrawal or use in total cash and cash equivalents on the statement of cash flows. ASU 2016-18 is effective for public entities with fiscal years beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company expects to adopt ASU 2016-18 on January 29, 2018, the first day of the Company’s first quarter for the fiscal year ending February 3, 2019, the Company’s fiscal year 2018. Upon adoption, the Company expects to include restricted cash in total cash and cash equivalents on the Company’s statement of cash flows.

Nature of Operations and Basis of Presentation (Policy)	12 Months Ended

Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations	Nature of Operations Duluth Holdings Inc. (“Duluth Trading” or the “Company”), a Wisconsin corporation, is a lifestyle brand of men’s and women’s casual wear, workwear and accessories sold exclusively through the Company’s own direct and retail channels. The direct segment, consisting of the Company’s website and catalogs, offers products nationwide. In 2010, the Company added retail to its omnichannel platform with the opening of its first store. Since then, Duluth Trading has expanded its retail presence, and as of January 28, 2018, the Company operated 28 retail stores and three outlet stores. The Company’s products are marketed under the Duluth Trading Company brand, with the majority of products being exclusively developed and sold as Duluth Trading branded merchandise. The Company has two classes of authorized common stock: Class A common stock and Class B common stock. The rights of holders of Class A common stock and Class B common stock are identical, except for voting and conversion rights. Each share of Class A common stock is entitled to ten votes per share and is convertible at any time into one share of Class B common stock. Each share of Class B common stock is entitled to one vote per share. The Company’s Class B common stock trades on the NASDAQ Global Select Market under the symbol “DLTH.”
Basis of Presentation	Basis of Presentation The consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). All intercompany balances and transactions have been eliminated. The Company’s fiscal year ends on the Sunday nearest to January 31 of the following year. Fiscal 2017, 2016 and 2015 ended on January 28, 2018, January 29, 2017, and January 31, 2016, respectively, and were all 52-week periods.
Seasonality of Business	Seasonality of Business The Company’s business is affected by the pattern of seasonality common to most retail apparel businesses. Historically, the Company has recognized a significant portion of its revenue and operating profit in the fourth fiscal quarter of each year as a result of increased sales during the holiday season.
Unaudited Pro Forma Net Income Information	Unaudited Pro Forma Net Income Information For the year ended January 31, 2016, the unaudited pro forma net income information gives effect to the conversion of the Company to a “C” corporation on November 25, 2015. Prior to such conversion, the Company was an “S” corporation and generally not subject to income taxes. The pro forma net income, therefore, includes an adjustment for income tax expense on the income attributable to controlling interest as if the Company had been a “C” corporation as of February 4, 2013 at an assumed combined federal, state and local effective tax rate of 40% , which approximates the calculated statutory rate for each period. No pro forma income tax expense was calculated on the income attributable to noncontrolling interest because this entity did not convert to a “C” corporation. For the year ended January 31, 2016, the unaudited pro forma basic and diluted net income per share of Class A and Class B common stock is computed using the unaudited pro forma net income, as discussed above.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policy)	12 Months Ended

Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the parent, Duluth Holdings Inc., and its wholly-owned subsidiary, Duluth Trading Company, LLC. Effective October 3, 2016, Duluth Trading Company, LLC was dissolved and no longer consolidated, which did not impact the Company’s consolidated financial statements. The Company also consolidates Schlecht Retail Ventures LLC (“SRV”) as a variable interest entity (see Note 5 “Variable Interest Entities”).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when the following four criteria are met: · persuasive evidence of an arrangement exists; · title has passed to the customer; · the sales price is fixed and determinable and no further obligation exists; and · collectability is reasonably assured. These criteria are met upon customer receipt of the product (for direct sales) or at the point of sale (for retail store transactions). At the time of revenue recognition, the Company provides for estimated costs that may be incurred for product warranties and sales returns. A liability is recognized at the time a gift card is sold, and revenue is recognized at the time the gift card is redeemed for merchandise.
Cost of Goods Sold and Selling, General and Administrative Expenses	Cost of Goods Sold and Selling, General and Administrative Expenses The following table illustrates the primary costs classified in cost of goods sold and selling, general and administrative expenses:     Cost of Goods Sold Selling, General and Administrative Expenses   Direct cost of purchased merchandise  Payroll and payroll-related expenses   Inventory shrinkage and inventory adjustments due to obsolescence  Third party logistics ("3PL")   Inbound freight  Occupancy expenses related to stores and operations at the Company's headquarters, including utilities   Freight from the Company's distribution centers to its stores  Depreciation and amortization   Advertising expenses, including television advertising, catalog production and mailing and print advertising costs   Freight associated with shipping product to customers   Consulting and professional fees 
Deferred Catalog and Advertising Expenses	Deferred Catalog and Advertising Expenses The Company’s direct-response advertising consists of producing, printing and mailing catalogs, which are capitalized as deferred catalog costs and amortized over the expected term of the related revenue stream (generally three to five months from the date catalogs are mailed). The Company’s non-direct response advertising costs are expensed as they are incurred. Non-direct response advertising costs primarily consist of billboards, web marketing programs, and radio and television advertisements. Catalog and advertising expenses were $ 88.6 million, $78.5 million and $65.2 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively.
Shipping and Processing	Shipping and Processing Shipping and processing revenue generated from customer orders has been classified as a component of net sales. Shipping and processing expense, including handling expense, has been classified as a component of selling, general and administrative expenses. The Company incurred shipping and processing expenses of $ 28.1 million, $24.3 million and $20.4 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively.
Income Taxes	Income Taxes Prior to November 25, 2015, the Company was taxed as an “S” corporation for income tax purposes under section 1362 of the Code, and therefore was not subject to federal and state income taxes. On November 25, 2015, the Company’s “S” corporation status terminated and the Company became subject to corporate-level federal and state income taxes at prevailing corporate rates. As a result of the conversion, effective November 25, 2015, the Company accounts for income taxes and related accounts using the liability method in accordance with ASC Topic 740, Income Taxes (“ASC 740”). Under ASC 740, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between U.S. GAAP and tax bases of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted tax rates in effect for the years in which the differences are expected to reverse, and recognizes the effect of a change in enacted rates in the period of enactment. A valuation allowance is established if it is more likely than not that some portion or all of the deferred income tax asset will not be realized. The Company establishes assets and liabilities for uncertain tax positions taken or expected to be taken in income tax returns, using a more-likely-than-not recognition threshold. The Company recognizes penalties and interest related to uncertain tax positions as income tax expense.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. At various times during the year, the Company has certain cash balances deposited in financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes it is not exposed to any significant credit risk.
Restricted Cash	Restricted Cash The Company’s restricted cash is held in an escrow account and is used to pay some portion of the construction loans entered into by the third party landlords (the “Landlords”) in connection with some of the Company’s retail store leases. The restricted cash is disbursed based on the escrow agreement entered into by and among the Landlords, the Company and the escrow agent.
Significant Suppliers	Significant Suppliers The Company’s principal supplier of inventory accounted for 50% , 51% and 54% of total inventory expenditures in fiscal 2017, fiscal 2016 and fiscal 2015, respectively. The Company also had a second supplier that accounted for 18% , 21% and 17% of total inventory expenditures in fiscal 2017, fiscal 2016 and fiscal 2015, respectively.
Inventory Valuation	Inventory Valuation Inventory, consisting of purchased product, is valued at the lower of cost and net realizable value, under the first-in, first-out method.
Property and Equipment	Property and Equipment Property and equipment consist of the following:      January 28, 2018 January 29, 2017  (in thousands)  Land and land improvements $ 3,055 $ 2,986  Leasehold improvements 20,985 12,752  Buildings 33,906 16,178  Vehicles 177 177  Warehouse equipment 5,850 3,939  Office equipment and furniture 22,161 11,125  Computer equipment 3,573 2,509  Software 7,540 6,659  97,247 56,325  Accumulated depreciation and amortization (22,739) (15,529)  74,508 40,796  Construction in progress 35,197 11,636  Property and equipment, net $ 109,705 $ 52,432  The Company recorded depreciation expense of $ 7.3 million, $ 4.6 million and $ 2.8 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively. The Company expenses all routine repair and maintenance costs that do not extend the estimated useful life of the asset. Property and equipment are carried at cost and are generally depreciated using the straight-line method over the estimated useful lives. Leasehold improvements are depreciated over the shorter of the lease term or estimated useful life. Depreciable lives by major classification are as follows:      Years  Land improvements 15 - 40  Leasehold improvements 3 - 15  Buildings 39  Vehicles 5 - 10  Warehouse equipment 5 - 15  Office equipment and furniture 3 - 10  Computer equipment 3 - 5  Software 3 - 5 
Build-to-Suit Lease	Build-to-Suit Lease The Company may at times be involved in the construction of stores to be leased by the Company and, depending on the extent to which the Company is involved, the Company may be deemed the owner of the leased premises for accounting purposes during the store construction period. For leases that the Company is deemed the owner of the property during the construction period, upon commencement of the construction project, the Company is required to capitalize the cash and non-cash assets contributed by the landlord for construction as property and equipment on the Company’s Consolidated Balance Sheets. Upon the completion of the construction project, the Company performs an analysis on the lease to determine if the Company qualifies for sale-leaseback treatment. For those qualifying leases, the finance lease obligation and the associated property and equipment are removed and the difference is reclassified to either prepaid or deferred rent and amortized over the lease term as an increase or decrease to rent expense. If the lease does not qualify for sale-leaseback treatment, the finance lease obligation is amortized over the lease term based on the rent payments in the lease agreement and the associated property and equipment are depreciated over the estimated useful life. As of January 28, 2018, and January 29, 2017, the Company capitalized $36.5 million and $6.6 million in property and equipment, respectively, and $0.3 million and $0.01 million in accumulated depreciation, respectively, and recorded a $26.6 million and a $3.3 million non-current liability, respectively, related to build-to-suit lease transactions in which the Company is considered the owner for accounting purposes.
Goodwill	Goodwill Goodwill represents the excess of purchase price over the fair value of net assets acquired. ASC Topic 350, Intangibles-Goodwill and Other , requires that goodwill be tested for impairment annually, or more often if an event or circumstance indicates that an impairment loss may have been incurred. The Company’s management uses its judgment in assessing whether goodwill may have become impaired between annual impairment tests. Indicators such as unexpected adverse business conditions, economic factors, competitive activities, loss of key personnel and acts by governments may signal that an asset has become impaired. Total goodwill is reported in the Company’s direct segment. Management performed a qualitative assessment of goodwill as of December 31, 2017, 2016 and 2015, and determined that it was more likely than not that the fair value of the Company was greater than its carrying amount; as such, no further evaluation of goodwill was deemed necessary. No impairment was recognized for the years ended January 28, 2018, January 29, 2017, or January 31, 2016.
Other Assets	Other Assets Other assets include loan origination fees, trade names and other non-current assets which are amortized over their estimated useful lives ranging from three to fifteen years. Other assets also include security deposits required by certain of the Company’s lease agreements and prepaid expenses which are not expected to be amortized within the next 12 months. Amortization expense was $0.1 million for each fiscal 2017, fiscal 2016 and fiscal 2015. Accumulated amortization was $0.3 million and $0.2 million as of January 28, 2018 and January 29, 2017, respectively. Scheduled future amortization of amortizable other assets are as follows as of January 28, 2018:      Fiscal year  (in thousands)  2018 $ 29  2019 26  2020 22  2021 21  2022 20  Thereafter 80  $ 198 
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company’s long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and the carrying value of the asset or group of assets. Such analyses necessarily involve judgment. For fiscal 2017, fiscal 2016 and fiscal 2015, management did not identify any events or changes in circumstances that indicated the potential impairment of long-lived assets.
Deferred Rent Obligation	Deferred Rent Obligation Certain of the Company’s operating lease agreements contain provisions for future rent increases, a rent free period, and/or a period in which rental payments are reduced (abated). For each such agreement, the total amount of rental payments due over the lease term is being charged to rent expense on the straight-line method over the term of the lease. The difference between rent expense recorded and the amount paid is charged to deferred rent obligations, the current portion of which is included in accrued other expenses in the consolidated balance sheets.
Store Pre-opening Costs	Store Pre-opening Costs Store pre-opening costs are expensed as incurred and are included in selling, general and administrative expenses.
Stock-Based Compensation	Stock-Based Compensation In connection with the IPO, the Company adopted the 2015 Equity Incentive Plan of Duluth Holdings Inc. (“2015 Plan”), which provides compensation alternatives such as stock options, shares, restricted stock, restricted stock units, deferred stock and performance share units, using or based on the Company’s Class B common stock. At the time of adoption, the Company reserved 1,614,631 shares of Class B common stock for the issuance of awards under the 2015 Plan. On the first day of the first four fiscal years following the IPO, the number of shares reserved for future issuance under the 2015 Plan will increase by 1.25% of the number of Class A and Class B common stock outstanding on the last day of the immediately preceding fiscal year. On January 29, 2018, the number of Class B common stock available for future issuance under the 2015 Plan was 2,653,439 shares. The Company accounts for its stock-based compensation plan in accordance with ASC Topic 718, Stock Compensation , which requires the Company to measure all share-based payments at grant date fair value and recognize the cost over the requisite service period of the award. Restricted stock issued to board members generally vests over a period of one year. Restricted stock issued to key employees and executives typically vests over a period of two to five years based on the terms for each individual award. The fair value of the restricted stock is determined based on the market value of the Company’s Class B common stock on the grant date. Restricted stock forfeitures are recognized as incurred. For restricted stock awards granted prior to the Company’s IPO, the fair value of the Company’s Class B common stock was calculated by an independent third party and was estimated by taking the average of the results of applying discounted cash flow and market comparable analyses. This value was then discounted due to the lack of marketability and liquidity of the restricted stock. Total stock compensation expense associated with restricted stock recognized by the Company was $ 1.6 million, $1.2 million and $0.7 million for fiscal 2017, fiscal 2016 and fiscal 2015, respectively, and is included in selling, general and administrative expenses on the Consolidated Statements of Operations. The following is a summary of the activity in the Company’s non-vested restricted stock during the years ended January 28, 2018, January, 29, 2017, and January 31, 2016:      Weighted average  grant date  fair value  Shares per share  Outstanding at February 1, 2015 246,708 $ 1.67  Granted 587,769 3.78  Vested (38,124) 3.35  Outstanding at January 31, 2016 796,353 3.15  Granted 59,814 23.41  Vested (61,455) 7.52  Outstanding at January 29, 2017 794,712 4.34  Granted 110,878 19.54  Vested (347,825) 3.04  Forfeited (21,294) 22.31  Outstanding at January 28, 2018 536,471 $ 7.60  At January 28, 2018, the Company had unrecognized compensation expense of $ 2.1 million related to the restricted stock awards, which is expected to be recognized over a weighted average period of 1.8 years.
Taxes Collected from Customers	Taxes Collected from Customers The Company presents all non-income government-assessed taxes (sales, use and value-added taxes) collected from its customers and remitted to governmental agencies on a net basis (excluded from revenue) in its consolidated financial statements.
Other Comprehensive Income or Loss	Other Comprehensive Income or Loss Other comprehensive income or loss represents the change in equity from non-shareholder or non-member transactions, which is not included in the statements of earnings but is reported as a separate component of shareholders’ equity. For fiscal 2016 and fiscal 2015, other comprehensive income or loss consists of changes in the fair value of the Company’s interest rate swap agreements.
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) , defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date (i.e., an exit price). The exit price is based on the amount that the holder of the asset or liability would receive or need to pay in an actual transaction (or in a hypothetical transaction if an actual transaction does not exist) at the measurement date. ASC 820 describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable, as follows: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying values of cash, accounts receivable, accounts payable and long-term obligations approximate fair value. The carrying value of goodwill and intangible assets are tested annually, or more frequently if an event occurs that indicates an impairment loss may have been incurred, using fair value measurements with unobservable inputs (Level 3). The carrying value of the Company's available-for-sale security was valued based on a discounted cash flow method (Level 3).
