| 2 | Summary of Significant Accounting Policies | ||||||||||||||||
| Use of Estimates—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates. | |||||||||||||||||
| Advertising Costs—The costs of advertising for online marketing arrangements, magazines, television and radio are expensed the first time the advertising takes place. Costs associated with the production and distribution of the Company’s catalogs are expensed as incurred. Advertising expense was $3.5 million and $3.6 million for the three months ended September 28, 2013 and September 29, 2012, respectively, and $12.9 million and $11.5 million for the nine months ended September 28, 2013 and September 29, 2012, respectively. | |||||||||||||||||
| Net Income Per Share—The Company’s basic net income per share excludes the dilutive effect of stock options, unvested restricted shares and unvested restricted share units. It is based upon the weighted average number of common shares outstanding during the period divided into net income. | |||||||||||||||||
| 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 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 total purchase price was approximately $50 million in cash and the assumption of certain liabilities, subject to certain conditions including a net working capital adjustment. The acquisition was financed by existing cash on the Company’s balance sheet. The results of operations of the acquired business are included in the Company’s results from the acquisition date. | |||||
| The acquisition resulted in goodwill primarily related to growth opportunities. The Company expensed acquisition and integration costs of $0.9 million and $3.9 million during the three and nine months ended September 28, 2013, respectively, which are included in the condensed consolidated statement of income within selling, general and administrative expenses. | |||||
| The purchase price of the acquisition has been allocated to the net tangible and intangible assets acquired, with the remainder recorded as goodwill on the basis of estimated fair values. The goodwill was allocated to the Company’s retail segment. The allocation is as follows (in thousands): | |||||

| Goodwill | $ | 33,385 | |||
| In the second fiscal quarter of 2013, the Company recorded $0.9 million as a reduction to working capital and an increase to goodwill to reflect the fair value of inventory. In the third quarter of 2013, the Company paid $0.2 million of additional consideration for this acquisition as a result of a net working capital adjustment. | |||||
| Intangible assets consist of a tradename of $2.4 million which is being amortized over the estimated useful life of 3 years. Long-term liabilities include unfavorable leases for certain retail locations of $0.8 million. The unfavorable lease liabilities are being amortized to rent expense over their respective lease terms, ranging from 2 to 9 years. Amortization expense for the unfavorable leases over the next five years is approximately $0.2 million per year for the first through third years and approximately $0.1 million per year for the fourth and fifth year. The goodwill of $33.4 million is expected to be amortized for tax purposes. | |||||
| From February 15, 2013 through September 28, 2013 the acquired business generated net sales of $48.0 million and net income of $1.7 million, excluding acquisition and integration costs. Pro forma results are not presented as the acquisition was not significant to the operating results for the three and nine months ended September 28, 2013 and Fiscal 2012. | |||||

| Revolving Credit Facility | |||||||||||||||||
| On September 25, 2009, the Company entered into a revolving credit facility (the “Revolving Credit Facility”). As of September 28, 2013, the terms of the Revolving Credit Facility, as amended, extend through September, 2015, and allow the Company to borrow up to $70.0 million subject to the terms of the facility. On December 20, 2012, Mariner was added as a borrower to the Revolving Credit Facility. The availability under the Revolving Credit Facility is subject to a borrowing base calculated on the value of certain accounts receivable from credit card companies as well as the inventory of Industries, Direct and Mariner. The obligations thereunder are secured by a security interest in substantially all of the assets of VSI, Industries, Direct and Mariner. Under the Revolving Credit Facility, VSI has guaranteed the Company’s obligations, and Industries, Direct and Mariner have each guaranteed the obligations of the other two respective entities. The Revolving Credit Facility provides for affirmative and negative covenants affecting VSI, Industries, Direct and Mariner. 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 the line of business, and restricts the types of hedging activities the Company can enter into. During the nine months ended September 28, 2013 there have been no borrowings under the Revolving Credit Facility. The unused available line of credit under the Revolving Credit Facility at September 28, 2013 was $69.4 million. | |||||||||||||||||
| Borrowings under the Revolving Credit Facility would accrue interest, at the Company’s option, at the rate per annum announced from time to time by the agent as its “prime rate,” or at a per annum rate equal to 2.50% above the adjusted Eurodollar rate. | |||||||||||||||||
| On October 11, 2013, the terms of the Revolving Credit Facility were amended in order to increase the borrowing capacity, as well as to reduce borrowing costs. Refer to Note 10. Subsequent Event for additional information. | |||||||||||||||||

| Equity Incentive Plans- The Company has two equity incentive plans that provide stock based compensation to certain directors, officers, consultants and employees of the Company; the 2006 Stock Option Plan (the “2006 Plan”) and the Vitamin Shoppe 2009 Equity Incentive Plan (the “2009 Plan”), under which the Company has granted stock options (includes non-qualified as well as performance based stock options), restricted shares (includes time based as well as performance based restricted shares) and restricted share units. The issuance of up to 7,453,678 shares of common stock is authorized under these plans. As of September 28, 2013, there were 2,641,907 shares available to grant under both plans. The stock options are exercisable at no less than the fair market value of the underlying shares on the date of grant, and restricted shares and restricted share units are issued at a value not less than the fair market value of the common shares on the date of the grant. Generally, stock options awarded shall become vested in four equal increments on each of the first, second, third and fourth anniversaries of the date on which such equity grants were awarded. Equity awards of restricted shares generally shall become vested between two and four years subsequent to the date on which such equity grants were awarded. However, regarding performance based stock options and performance based restricted shares, vesting is dependent not only on the passage of time, but also on the attainment of certain internal performance metrics. The vesting requirements for performance based stock options and performance based restricted shares permit a catch-up of vesting at the end of the vesting period. Restricted share units generally shall become vested one year subsequent to the date on which such equity grants were awarded. The stock options generally have a maximum term of 10 years.

| Stock-based compensation cost is measured at the grant date based on the fair value of awards and is recognized as expense over the vesting period, net of anticipated forfeitures. With the exception of restricted shares and restricted share units, determining the fair value of stock-based awards at the grant date requires considerable judgment, including estimating expected volatility, expected term and risk-free rate. The expected volatility is derived from the average volatility of similar actively traded companies over our expected holdings periods, as well as the Company’s own volatility, which is weighted to adjust for the shorter trading history. Generally, the expected holding period of non performance based options is calculated using the simplified method using the vesting term of 4 years and the contractual term of 10 years, resulting in a holding period of 6.25 years. Certain limited grants have contractual terms of 7.5 years, and/or shorter vesting periods and as such have calculated holding periods of 4 to 5 years. The Company’s performance based stock option grants vest annually over four years depending on a particular year’s attainment of certain internal financial performance metrics. For accounting purposes, performance based stock option grants are measured, and expense is calculated and recorded, subsequent to the determination that the achievement of the pre-established performance targets are probable, over the relevant service period. The target metrics underlying the vesting of performance based stock option grants are established each year. Accordingly, the holding period for performance based stock option grants is calculated using the vesting term of 1 year and the remainder of the contractual term of 10 years, depending on which year of the four year grant is currently vesting; e.g. 25% of the grant vesting in year two of the grant would have a holding period calculated using 1 year and the remaining 9 years of the contractual term. The simplified method was chosen as a means to determine the Company’s holding period as prior to November 2009 there was no historical option exercise experience due to the Company being privately held. As of September 28, 2013, there continues to be insufficient information for purposes of determining a Company specific holding period. The risk-free interest rate is derived from the average yields of zero-coupon U.S. Treasury Strips for the expected holding period of each of the Company’s stock option grants. Compensation expense resulting from the granting of restricted shares and restricted share units is based on the grant date fair value of those common shares and is recognized generally over the two to four year vesting period for restricted shares and over the one year vesting period for restricted share units. | |||||||||||||||||
| The weighted-average fair value of previously granted performance based stock options during the three and nine months ended September 28, 2013, was $12.44 and $23.76, respectively. The weighted-average fair value of previously granted performance based stock options during the three and nine months ended September 29, 2012, was $23.71 and $23.20, respectively. These valuations represent the fair value of subsequent annual tranches of performance based stock option grants. 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: | |||||||||||||||||

| Treasury Stock- As part of the Company’s stock plans, the Company makes required tax payments on behalf of employees as their restricted shares vest. Beginning in the second quarter of fiscal 2013, the Company withholds the number of vested shares having a value on the date of vesting equal to the tax obligation. The shares withheld are recorded as treasury shares. During the nine months ended September 28, 2013, the Company purchased 6,316 shares in settlement of employees’ tax obligations for a total of $0.3 million. The Company accounts for treasury stock using the cost method. | |||||||||||||||||
| Employee Stock Purchase Plan- Pursuant to the Vitamin Shoppe 2010 Employee Stock Purchase Plan (the “ESPP”), shares of common stock are issued at the end of each calendar quarter (the “Participation Period”) 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. During the nine months ended September 28, 2013 and September 29, 2012, 15,184 shares and 18,897 shares, respectively, of the Company’s common stock were purchased under the ESPP. As of September 28, 2013, there was approximately $0.2 million of employee payroll deductions available under the ESPP for purchasing common shares on the September 30, 2013 purchase date. | |||||||||||||||||
| Compensation expense attributable to stock-based compensation for the three and nine months ended September 28, 2013 was approximately $2.5 million and $6.8 million, respectively, and for the three and nine months ended September 29, 2012 was approximately $1.8 million and $4.7 million, respectively. As of September 28, 2013, 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 $12.3 million, and the related weighted-average period over which it is expected to be recognized is 1.7 years. There were 871,780 and 175,799 vested and non-vested outstanding options, respectively, at September 28, 2013. There were 390,709 unvested restricted shares and 6,675 unvested restricted share units at September 28, 2013. 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 stock option granting. The estimated value of future forfeitures for stock options, restricted shares and restricted share units as of September 28, 2013 is approximately $0.7 million. | |||||||||||||||||

| The Company currently operates two business segments, retail and direct. 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, retail and direct, as well as corporate costs. The retail segment includes the Company’s retail stores. The retail segment generates revenue primarily through the sale of third-party branded and proprietary branded vitamins, minerals, herbs, supplements, sports nutrition and other health and wellness products through Vitamin Shoppe, Super Supplements and Vitapath retail stores throughout the United States and in Canada.
