Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Use of Estimates Cash and Cash Equivalents Accounts Receivable The following table details the activity and balances for the Company’s customer allowances for the years ended December 26, 2015 and December 27, 2014 (in thousands): Balance at Year Additions Deductions Balance at End of Period Ended December 26, 2015 $ 1,883.2 $ 2,751.9 $ (3,738.4 ) $ 896.7 Period Ended December 27, 2014 $ — $ 3,194.2 $ (1,311.0 ) $ 1,883.2 Inventories Balance at Beginning of Fiscal Year Amounts Cost of Goods Sold Write-Offs Against Reserves Balance at End of Fiscal Year Fiscal Year Ended December 26, 2015 $ 3,121.0 $ 9,809.2 $ (7,991.1 ) $ 4,939.1 Fiscal Year Ended December 27, 2014 2,640.3 5,866.6 (5,385.9 ) 3,121.0 Fiscal Year Ended December 28, 2013 1,841.2 4,637.9 (3,838.8 ) 2,640.3 Property and Equipment, Net Impairment of Long-Lived Assets Goodwill and Other Intangibles In Fiscal 2015, the Company performed a quantitative analysis of its retail, direct and manufacturing reporting units and determined that the fair value of these reporting units and indefinite-lived tradenames were substantially greater than their respective carrying values, with the exception of the manufacturing reporting unit. Since the acquisition, Nutri-Force has experienced disruption in its ability to optimize production capacity and correspondingly has experienced lower service levels to customers. As of the annual testing date, the fair value of the manufacturing reporting unit exceeded the carrying value by approximately 5%. Goodwill for the manufacturing reporting unit is $32.6 million. The assumptions which impact the estimated fair value include management projections, the weighted average cost of capital percentage including the company specific risk premium and the selection of comparable companies. The uncertainty associated with the key assumptions relates primarily to the performance of Nutri-Force in comparison to management projections, which includes improvements in operating efficiencies, the ability to transition additional Vitamin Shoppe branded products, and increase sales to third party customers. The Company has taken steps to improve the operations at Nutri-Force, including the hiring of new leadership and the engagement of third-party manufacturing consultants to implement and improve manufacturing processes. The Company believes the disruption noted above should not impact the long-term opportunity from the Nutri-Force acquisition. Although the Company believes it has used reasonable estimates and assumptions to calculate the fair value of the manufacturing reporting unit, these estimates and assumptions could be materially different from actual results. If actual market conditions are less favorable than those projected, or if events occur or circumstances change that would reduce the fair value of this reporting unit below its carrying value, the Company may be required to conduct an interim test and possibly recognize impairment charges, which may be material, in future periods. There have been no impairment charges related to other intangibles during Fiscal 2015, Fiscal 2014 and Fiscal 2013. Rent Expenses, Deferred Rent and Landlord Construction Allowances Revenue Recognition Cost of Goods Sold Vendor Allowances Frequent Buyer Program Store Pre-opening Costs Advertising Costs Online Marketing Arrangements Income Taxes The Company accounts for tax positions based on the provisions of the accounting literature related to accounting for uncertainty in income tax positions. Such literature provides guidance for the recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For tax positions that are not more likely than not sustainable upon audit, the Company recognizes the largest amount of the benefit that is more likely than not to be sustained. The Company makes estimates of the potential liability based on our assessment of all potential tax exposures. In addition, the Company uses factors such as applicable tax laws and regulations, current information and past experience with similar issues to make these assessments. The tax positions are analyzed regularly and adjustments are made as events occur that warrant adjustments for those positions. The Company records interest expense and penalties payable to relevant tax authorities as income tax expense. Concentrations of Credit Risk The Company had two suppliers from whom we purchased at least 5% of our merchandise during Fiscal 2015 and one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2014 and Fiscal 2013. We purchased approximately 17% of our total merchandise from these suppliers during Fiscal 2015 and approximately 12% during Fiscal 2014 and 10% during Fiscal 2013. The Company is subject to concentrations of credit risk associated with cash and cash equivalents, and at times holds cash balances in excess of Federal Deposit Insurance Corporation limits. Stock-Based Compensation Expense related to shares purchased under the Company’s Employee Stock Purchase Plan (“ESPP”) is accounted for based on fair value recognition requirements similar to stock options. ESPP participation occurs each calendar quarter (the “Participation Period”) and the expense of which is subject to employee participation in the plan. Under the ESPP, participating employees are allowed to purchase shares at 85% of the lower of the market price of the Company’s common stock at either the first or last trading day of the Participation Period. Compensation expense related to the ESPP is based on the estimated fair value of the discount and purchase price offered on the estimated shares to be purchased under the ESPP. Expense is calculated quarterly, based on the employee contributions made over the applicable three-month Participation Period, using volatility and risk free rates applicable to that three-month period. Net Income Per Share Diluted net income per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Stock options, unvested restricted shares, warrants and unvested restricted share units are included as potential dilutive securities for the periods applicable, using the treasury stock method to the extent dilutive. The components of the calculation of basic net income per common share and diluted net income per common share are as follows (in thousands except share and per share data): Fiscal Year Ended December 26, 2015 December 27, 2014 December 28, 2013 Numerator: Net income available to common stockholders $ 53,171 $ 61,241 $ 66,546 Denominator: Basic weighted average common shares outstanding 28,954,804 30,239,183 29,992,620 Effect of dilutive securities: Stock options 97,114 235,057 402,814 Restricted shares 150,353 184,995 141,573 Restricted share units 1,158 4,870 4,050 Diluted weighted average common shares outstanding 29,203,429 30,664,105 30,541,057 Basic net income per common share $ 1.84 $ 2.03 $ 2.22 Diluted net income per common share $ 1.82 $ 2.00 $ 2.18 Stock options and restricted shares for the fiscal years ended December 26, 2015, December 27, 2014 and December 28, 2013 for 48,538, 18,089 and 23,319 shares, respectively, have been excluded from the above calculation as they were anti-dilutive. The Company has the intent and ability to settle the principal portion of its Convertible Notes in cash, and as such, has applied the treasury stock method, which has resulted in the underlying convertible shares being anti-dilutive in Fiscal 2015 as the Company’s average stock price from the issuance of the Convertible Notes through December 26, 2015 is less than the conversion price. Refer to Note 8. Credit Arrangements for additional information on the Convertible Notes. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize 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 July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. As a result of this deferral, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company is evaluating ASU 2014-09 to determine if this guidance will have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-03 (“ASU 2015-03”), Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. This standard does not affect the recognition and measurement guidance for debt issuance costs. Amortization of such costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted and the Company has elected to early adopt this standard, concurrent with the issuance of the Convertible Notes. As a result, issuance costs attributable to the liability portion of the Convertible Notes have been recorded as a direct deduction from the carrying amount of the Convertible Notes liability. The adoption of ASU 2015-03 has no impact on any prior period financial statements presented, as debt issuance costs previously incurred relate to the Company’s revolving credit facility and will continue to be recorded in other long-term assets. In July 2015, the FASB issued Accounting Standards Update No. 2015-11 (“ASU 2015-11”), Simplifying the Measurement of Inventory (Topic 330). ASU 2015-11 simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2015-11 is permitted. The Company is evaluating ASU 2015-11 to determine if this guidance will have a material impact on the Company’s consolidated financial statements.

Credit Arrangements	8. Credit Arrangements Convertible Senior Notes due 2020 On December 9, 2015, the Company completed an offering of $143.8 million of its 2.25% Convertible Senior Notes due 2020 (the “Convertible Notes”). The Convertible Notes are senior unsecured obligations of the Company. Interest on the Convertible Notes is payable on June 1 and December 1 of each year, commencing on June 1, 2016 until their maturity date of December 1, 2020. The Company may not redeem the Convertible Notes prior to the maturity date. Prior to July 1, 2020, the Convertible Notes will be convertible only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2016, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after July 1, 2020 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. The Convertible Notes will be convertible at an initial conversion rate of 25.1625 shares of the Company’s common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $39.74. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company is required to increase, in certain circumstances, the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event including customary conversion rate adjustments in connection with a “make-whole fundamental change” as defined. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company allocated the principal amount of the Convertible Notes between its liability and equity components (see table below). The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the conversion feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Convertible Notes as a whole. The equity component was recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Convertible Notes over the carrying amount of the liability component was recorded as a debt discount, and is being amortized to interest expense using an effective interest rate of 3.8% over the term of the Convertible Notes. The Company allocated the total amount of transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the liability component of the Convertible Notes, and are being amortized to interest expense using the effective interest method through the maturity date. Transaction costs attributable to the equity component were netted with the equity component of the Convertible Notes in additional paid-in capital. The Convertible Notes consist of the following components as of December 26, 2015 (in thousands): Liability component: Principal $ 143,750 Conversion feature (24,800 ) Liability portion of debt issuance costs (3,800 ) Amortization 260 Net carrying amount $ 115,410 Equity component: Conversion feature $ 24,800 Equity portion of debt issuance costs (793 ) Deferred taxes 941 Net carrying amount $ 24,948 In connection with the issuance of the Convertible Notes, the Company entered into convertible note hedge transactions for which it paid an aggregate $26.4 million. In addition, the Company sold warrants for which it received aggregate proceeds of $13.0 million. The convertible note hedge transactions are expected generally to reduce potential dilution of the Company’s common stock upon any conversion of notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes. However, the warrant transaction could separately have a dilutive effect to the extent that the market value per share of the Company’s common stock exceeds the applicable strike price of the warrant transactions, which is approximately $52.99 at inception. As these transactions meet certain accounting criteria, the convertible note hedge and warrant transactions are recorded in stockholders’ equity, are not accounted for as derivatives and are not remeasured each reporting period. The net proceeds from the Convertible Notes and related transactions of $125.7 million, net of commissions and offering costs of $4.6 million, are being used to repurchase shares of the Company’s common stock under the Company’s share repurchase programs. Refer to Note 11. Share Repurchase Programs for additional information. Revolving Credit Facility As of December 26, 2015 and December 27, 2014, the Company had $8.0 million of borrowings outstanding on its Revolving Credit Facility. Subject to the terms of the Revolving Credit Facility, which has a maturity date of October 11, 2018, the Company may borrow up to $90.0 million, with a Company option to increase the facility up to a total of $150.0 million. The availability under the Revolving Credit Facility is subject to a borrowing base calculated on the value of certain accounts receivable as well as certain inventory of the Company. The obligations thereunder are secured by a security interest in substantially all of the assets of the Company. Under the Revolving Credit Facility, VSI has guaranteed the Company’s obligations, and Industries and its wholly-owned subsidiaries have each guaranteed the obligations of the other respective entities. The Revolving Credit Facility provides for affirmative and negative covenants affecting the Company. The Revolving Credit Facility restricts, among other things, the Company’s ability to incur indebtedness, create or permit liens on the Company’s assets, declare or pay dividends and make certain other restricted payments, consolidate, merge or recapitalize, sell assets, make certain investments, loans or other advances, enter into transactions with affiliates, change our line of business, and restricts the types of hedging activities the Company can enter into. The largest amount borrowed at any given point during Fiscal 2015 was $28.0 million. The unused available line of credit under the Revolving Credit Facility at December 26, 2015 was $79.1 million. Borrowings under the Revolving Credit Facility accrue interest, at the Company’s option, at the rate per annum based on an “alternative base rate” plus 0.25% or 0.50% or the adjusted Eurodollar rate plus 1.25% or 1.50%, in each case with the higher spread applicable in the event that the aggregate amount of the borrowings under the Revolving Credit Facility exceeds 50% of the borrowing base availability under the Revolving Credit Facility. The weighted average interest rate for the Revolving Credit facility for Fiscal 2015 was 1.47%. The commitment fee on the undrawn portion of the $90.0 million Revolving Credit Facility was 0.25% as of December 26, 2015 and December 27, 2014. Interest expense, net for Fiscal 2015, 2014 and 2013 consists of the following (in thousands): Fiscal Year Ended December 26, December 27, December 28, Interest / fees on the revolving credit facility and other interest $ 487 $ 344 $ 419 Amortization of deferred financing fees 237 164 96 Interest on convertible notes 159 — — Amortization of debt discount on convertible notes 223 — — Interest income (1 ) (13 ) (20 ) Interest expense, net $ 1,105 $ 495 $ 495

The temporary differences and carryforwards that give rise to deferred tax assets and liabilities at December 26, 2015 and December 27, 2014 are as follows (in thousands): December 26, December 27, Deferred tax assets: Net operating loss carryforward $ 1,806 $ 1,142 Deferred rent 11,389 11,861 Tenant allowance 4,215 3,667 Deferred sales 4,011 4,386 General accrued liabilities 6,790 6,165 Deferred wages and compensation 569 711 Inventory 7,205 4,339 Equity compensation expense 3,400 6,304 Debt 1,002 — Other 3,299 2,062 43,686 40,637 Valuation allowance (1,806 ) (1,142 ) Deferred tax assets 41,880 39,495 Deferred tax liabilities: Trade name and goodwill (29,777 ) (29,368 ) Accumulated depreciation (9,488 ) (9,612 ) Prepaid expenses (2,012 ) (2,217 ) Deferred tax liabilities (41,277 ) (41,197 ) Net deferred tax asset (liability) $ 603 $ (1,702 ) In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (“ASU 2015-17”), Balance Sheet Classification of Deferred Taxes (Topic 740) to simplify the presentation of deferred taxes by requiring the classification of all deferred tax assets and liabilities as noncurrent in a classified statement of financial position. The Company is electing a prospective early application of ASU 2015-17 for Fiscal 2015. Prior periods were not retrospectively adjusted. Management periodically assesses whether the Company is more likely than not to realize some or all of its deferred tax assets. As of December 26, 2015, with the exception of $1.8 million of deferred tax assets arising from a foreign and state net operating loss carryforward against which there is a valuation allowance (see above table), management determined that the Company is more likely than not to realize the deferred tax assets detailed above. Realization of deferred tax assets associated with the state net operating loss carryforwards is dependent upon generating sufficient taxable income prior to their expiration by tax jurisdiction. The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate was approximately $0.4 million at December 26, 2015, $0.4 million at December 27, 2014 and $0.3 million at December 28, 2013. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Balance at December 29, 2012 $ 5,630 Additions based on tax positions related to the current year 13 Additions for tax positions of prior years — Decreases for tax positions of prior years due to revaluation of positions (4,627 ) Decreases for tax positions of prior years due to lapse of statutes (612 ) Balance at December 28, 2013 $ 404 Additions based on tax positions related to the current year 148 Additions for tax positions of prior years — Decreases for tax positions of prior years due to revaluation of positions — Decreases for tax positions of prior years due to lapse of statutes (93 ) Balance at December 27, 2014 $ 459 Additions based on tax positions related to the current year 107 Additions for tax positions of prior years — Decreases for tax positions of prior years due to revaluation of positions — Decreases for tax positions of prior years due to lapse of statutes (97 ) Balance at December 26, 2015 $ 469 The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state jurisdictions, Puerto Rico and Canada. The Company recognizes interest related to uncertain tax positions in income tax expense. The Company is no longer subject to U.S. federal examinations by tax authorities for years before 2012 and for state examinations before 2009. However, the tax authorities still have the ability to review the relevance of net operating loss carryforwards created in closed years if such tax attributes are utilized in open years (subsequent to 2009). The Company has domestic (U.S. state) and foreign net operating losses of approximately $1.4 million and $6.3 million at December 26, 2015, against which a full valuation allowance is recorded. Domestic net operating losses generated in the state of New Jersey will continue to expire annually through Fiscal 2032. The Company’s foreign net operating loss is generated through operations in Canada, and will expire in Fiscal 2034.

As of December 26, 2015, the remaining unrecognized stock based compensation expense for non-vested stock options, restricted shares and restricted share units to be expensed in future periods is $6.1 million, and the related weighted average period over which it is expected to be recognized is 1.6 years. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical forfeiture rate since the inception of granting stock based awards. The estimated value of future forfeitures for stock options, restricted shares and restricted share units as of December 26, 2015 is approximately $0.6 million. The weighted average grant date fair value of stock options was $18.99 and $23.76 for Fiscal 2014 and Fiscal 2013, respectively. These valuations represent the fair value of subsequent annual tranches of performance based stock option grants, and there were no such valuations during Fiscal 2015. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: December 27, 2014 December 28, 2013 Expected dividend yield 0.0 % 0.0 % Weighted average expected volatility 35.3 % 39.0 % Weighted average risk-free interest rate 1.4 % 0.6 % Expected holding period(s) 4.00 - 4.43 years 4.00 - 4.93 years Treasury Stock

Share Repurchase Programs	11. Share Repurchase Programs On August 5, 2014, May 6, 2015 and November 23, 2015, the Company’s board of directors approved share repurchase programs that enable the Company to purchase up to an aggregate of $300 million of its shares of common stock from time to time over three year periods ending on August 4, 2017, May 5, 2018 and November 22, 2018, respectively. As of December 26, 2015, 5,511,769 shares have been repurchased for a total of $203.9 million. The repurchase program does not obligate the Company to acquire any specific number of shares of its common stock and may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing such shares, the availability of alternative investment opportunities, liquidity, and other factors deemed appropriate. These factors may also affect the timing and amount of share repurchases. During Fiscal 2015 and Fiscal 2014, the Company repurchased 1,182,990 and 201,000 shares, respectively, of its common stock in the open market. The shares were retired upon repurchase. Open market share repurchases were $44.2 million in Fiscal 2015 and $7.8 million in Fiscal 2014 with average repurchase prices per share of $37.38 and $38.88, respectively. Additionally, the Company has entered into accelerated share repurchase (“ASR”) arrangements with financial institutions. In exchange for an up-front payment, the financial institutions initially deliver shares of the Company’s common stock. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, is determined at the end of the purchase period of each ASR based on the volume weighted-average price of the Company’s common stock during that period. The shares are retired in the periods they are delivered, and each up-front payment is accounted for as a reduction to stockholders’ equity in the Company’s Consolidated Balance Sheet in the period the payment was made. The Company reflects each ASR as a repurchase of common stock in the period delivered for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The ASRs met all of the applicable criteria for equity classification, and therefore, were not accounted for as derivative instruments. The following table summarizes the Company’s ASR arrangements: Beginning of ASR Period Up-front Initial Share End of ASR Period Final Average November, 2014 $ 50.0 982,714 January, 2015 88,325 $ 46.68 December, 2015 $ 50.0 1,391,940 * * * * To be determined at the end of the purchase period of the ASR. In December 2015, the Company also repurchased 1,664,800 shares of its common stock for $51.9 million, or $31.17 per share, from purchasers of the Convertible Notes in privately negotiated transactions.

Benefit Plans	12. Benefit Plans The Company sponsors the Vitamin Shoppe Industries, Inc. 401(k) Plan (“401k Plan”). Employees who have completed one month of service are eligible to participate in the 401k Plan. The 401k Plan provides for participant contributions of 1% to 100% of participant compensation into deferred savings, subject to IRS limitations. The 401k Plan provides for Company contributions upon the participant meeting the eligibility requirements. Participants are 100% vested in the Company matching contribution upon receipt. The Company matching contribution is 100% of the first 3% of participant compensation contributed to the 401k Plan and 50% of the next 2% of participant compensation contributed to the 401k Plan. The Company may make discretionary contributions for each 401k Plan year. The Company recognized expenses for the 401k Plan of $1.9 million in Fiscal 2015, $1.6 million in Fiscal 2014, and $1.5 million in Fiscal 2013. The Company had a Non-qualified Deferred Compensation Plan (“DC Plan”) which was terminated in January 2015 and did not have a material effect on the Company’s financial statements. The DC Plan allowed participants the opportunity to defer pretax amounts up to 75% of base salary and up to 100% of other eligible compensation. The DC Plan was primarily funded by elective contributions made by the participants. The assets of the DC Plan were $2.7 million at December 27, 2014. Accordingly, gains and losses on the underlying investments, which are held in a Rabbi Trust, were recognized in the consolidated statements of income. The liabilities for the DC Plan were $2.3 million at December 27, 2014.

Segment Reporting [Abstract]
Segment and Product Data	15. Segment and Product Data The Company currently operates three business segments, retail, direct and manufacturing. The operating segments are segments of the Company for which separate financial information is available and for which operating results are evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. The Company’s management evaluates segment operating results based on several indicators. The primary key performance indicators are sales and operating income for each segment. The table below represents key financial information for each of the Company’s business segments as well as corporate costs. The retail segment primarily includes the Company’s retail stores. The retail segment generates revenue primarily through the sale of VMS products through Vitamin Shoppe, Super Supplements and Vitapath retail stores in the United States, Puerto Rico and in Canada. The direct segment generates revenue through the sale of VMS products primarily through the Company’s websites. The Company’s websites offer customers online access to a full assortment of approximately 19,400 SKUs. The manufacturing segment supplies the retail and direct segments, along with various thirds parties, with finished products for sale. Corporate costs represent all other expenses not allocated to the retail, direct or manufacturing segments which include, but are not limited to: human resources, legal, retail management, direct management, finance, information technology, depreciation (primarily related to assets utilized by the retail and direct business segments as well as corporate assets) and amortization, and various other corporate level activity related expenses. Intercompany sales transactions are eliminated in consolidation. The Company’s segments are designed to allocate resources internally and provide a framework to determine management responsibility. The Company has allocated $165.3 million, $45.3 million and $32.6 million of its recorded goodwill to the retail, direct and manufacturing segments, respectively. The Company does not have identifiable assets separated by segment, with the exception of the identifiable assets of the manufacturing segment, which were $88.4 million and $96.2 million as of December 26, 2015 and December 27, 2014, respectively. Capital expenditures for the manufacturing segment during Fiscal 2015 were $3.5 million and from the acquisition date of June 6, 2014 through December 27, 2014 were approximately $0.5 million. At December 26, 2015 and December 27, 2014, long lived assets of the manufacturing segment were $60.4 million and $59.9 million, respectively. Depreciation and amortization expense, included in selling, general and administrative expenses, for the manufacturing segment during Fiscal 2015 was $1.5 million and from the acquisition date of June 6, 2014 through December 27, 2014 was $0.9 million.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	16. Fair Value of Financial Instruments The fair value hierarchy requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are defined as follows: • Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities. • Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. The Company’s financial instruments include cash, accounts receivable, accounts payable and its revolving credit facility. The Company believes that the recorded values of these financial instruments approximate their fair values due to their nature and respective durations. The fair value and carrying value of the Convertible Notes as of December 26, 2015 was $119.8 million and $115.4 million, respectively. The fair value of the Convertible Notes was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of the Company’s Convertible Notes, when available, the Company’s stock price and interest rates based on similar debt issued by parties with credit ratings similar to the Company (Level 2). Certain assets are measured at fair value on a non-recurring basis, that is, the assets are subject to fair value adjustments in certain circumstances such as when there is evidence of impairment. These measures of fair value, and related inputs, are considered level 2 or 3 measures under the fair value hierarchy.

Goodwill and Other Intangibles	Goodwill and Other Intangibles In Fiscal 2015, the Company performed a quantitative analysis of its retail, direct and manufacturing reporting units and determined that the fair value of these reporting units and indefinite-lived tradenames were substantially greater than their respective carrying values, with the exception of the manufacturing reporting unit. Since the acquisition, Nutri-Force has experienced disruption in its ability to optimize production capacity and correspondingly has experienced lower service levels to customers. As of the annual testing date, the fair value of the manufacturing reporting unit exceeded the carrying value by approximately 5%. Goodwill for the manufacturing reporting unit is $32.6 million. The assumptions which impact the estimated fair value include management projections, the weighted average cost of capital percentage including the company specific risk premium and the selection of comparable companies. The uncertainty associated with the key assumptions relates primarily to the performance of Nutri-Force in comparison to management projections, which includes improvements in operating efficiencies, the ability to transition additional Vitamin Shoppe branded products, and increase sales to third party customers. The Company has taken steps to improve the operations at Nutri-Force, including the hiring of new leadership and the engagement of third-party manufacturing consultants to implement and improve manufacturing processes. The Company believes the disruption noted above should not impact the long-term opportunity from the Nutri-Force acquisition. Although the Company believes it has used reasonable estimates and assumptions to calculate the fair value of the manufacturing reporting unit, these estimates and assumptions could be materially different from actual results. If actual market conditions are less favorable than those projected, or if events occur or circumstances change that would reduce the fair value of this reporting unit below its carrying value, the Company may be required to conduct an interim test and possibly recognize impairment charges, which may be material, in future periods. There have been no impairment charges related to other intangibles during Fiscal 2015, Fiscal 2014 and Fiscal 2013.

Income Taxes	Income Taxes The Company accounts for tax positions based on the provisions of the accounting literature related to accounting for uncertainty in income tax positions. Such literature provides guidance for the recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For tax positions that are not more likely than not sustainable upon audit, the Company recognizes the largest amount of the benefit that is more likely than not to be sustained. The Company makes estimates of the potential liability based on our assessment of all potential tax exposures. In addition, the Company uses factors such as applicable tax laws and regulations, current information and past experience with similar issues to make these assessments. The tax positions are analyzed regularly and adjustments are made as events occur that warrant adjustments for those positions. The Company records interest expense and penalties payable to relevant tax authorities as income tax expense.
Concentrations of Credit Risk	Concentrations of Credit Risk The Company had two suppliers from whom we purchased at least 5% of our merchandise during Fiscal 2015 and one supplier from whom we purchased at least 5% of our merchandise during Fiscal 2014 and Fiscal 2013. We purchased approximately 17% of our total merchandise from these suppliers during Fiscal 2015 and approximately 12% during Fiscal 2014 and 10% during Fiscal 2013. The Company is subject to concentrations of credit risk associated with cash and cash equivalents, and at times holds cash balances in excess of Federal Deposit Insurance Corporation limits.
Stock-Based Compensation	Stock-Based Compensation Expense related to shares purchased under the Company’s Employee Stock Purchase Plan (“ESPP”) is accounted for based on fair value recognition requirements similar to stock options. ESPP participation occurs each calendar quarter (the “Participation Period”) and the expense of which is subject to employee participation in the plan. Under the ESPP, participating employees are allowed to purchase shares at 85% of the lower of the market price of the Company’s common stock at either the first or last trading day of the Participation Period. Compensation expense related to the ESPP is based on the estimated fair value of the discount and purchase price offered on the estimated shares to be purchased under the ESPP. Expense is calculated quarterly, based on the employee contributions made over the applicable three-month Participation Period, using volatility and risk free rates applicable to that three-month period.
Net Income Per Share	Net Income Per Share Diluted net income per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Stock options, unvested restricted shares, warrants and unvested restricted share units are included as potential dilutive securities for the periods applicable, using the treasury stock method to the extent dilutive. The components of the calculation of basic net income per common share and diluted net income per common share are as follows (in thousands except share and per share data): Fiscal Year Ended December 26, 2015 December 27, 2014 December 28, 2013 Numerator: Net income available to common stockholders $ 53,171 $ 61,241 $ 66,546 Denominator: Basic weighted average common shares outstanding 28,954,804 30,239,183 29,992,620 Effect of dilutive securities: Stock options 97,114 235,057 402,814 Restricted shares 150,353 184,995 141,573 Restricted share units 1,158 4,870 4,050 Diluted weighted average common shares outstanding 29,203,429 30,664,105 30,541,057 Basic net income per common share $ 1.84 $ 2.03 $ 2.22 Diluted net income per common share $ 1.82 $ 2.00 $ 2.18 Stock options and restricted shares for the fiscal years ended December 26, 2015, December 27, 2014 and December 28, 2013 for 48,538, 18,089 and 23,319 shares, respectively, have been excluded from the above calculation as they were anti-dilutive. The Company has the intent and ability to settle the principal portion of its Convertible Notes in cash, and as such, has applied the treasury stock method, which has resulted in the underlying convertible shares being anti-dilutive in Fiscal 2015 as the Company’s average stock price from the issuance of the Convertible Notes through December 26, 2015 is less than the conversion price. Refer to Note 8. Credit Arrangements for additional information on the Convertible Notes.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize 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 July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. As a result of this deferral, ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company is evaluating ASU 2014-09 to determine if this guidance will have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-03 (“ASU 2015-03”), Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. This standard does not affect the recognition and measurement guidance for debt issuance costs. Amortization of such costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted and the Company has elected to early adopt this standard, concurrent with the issuance of the Convertible Notes. As a result, issuance costs attributable to the liability portion of the Convertible Notes have been recorded as a direct deduction from the carrying amount of the Convertible Notes liability. The adoption of ASU 2015-03 has no impact on any prior period financial statements presented, as debt issuance costs previously incurred relate to the Company’s revolving credit facility and will continue to be recorded in other long-term assets. In July 2015, the FASB issued Accounting Standards Update No. 2015-11 (“ASU 2015-11”), Simplifying the Measurement of Inventory (Topic 330). ASU 2015-11 simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2015-11 is permitted. The Company is evaluating ASU 2015-11 to determine if this guidance will have a material impact on the Company’s consolidated financial statements.
